Abstract
BACKGROUND If survival could be reliably predicted many patients could be safely managed outside of hospital in an ambulatory care setting. AIM Comparison of common laboratory findings, co-morbidities, mobility and vital signs as predictors of mortality of acutely ill emergency department (ED) attendees. DESIGN Prospective observational study. METHODS Secondary analysis of 1334 consenting acutely ill patients attending a Danish ED. RESULTS 67 (5%) out of 1334 patients died within 100 days. After logistic regression seven predictors of 100 days mortality remained significant: an albumin level ≤34 gm/l, D-dimer level >0.51 mg/l, an Asadollahi score (based on admission laboratory data and age) ≥12, a platelet count <159 X 1000/ml, impaired mobility on presentation, a respiratory rate ≥30 bpm and a Charlson co-morbidity index ≥3. Only 5 of the 442 without any of these variables died within 365 days. Only one of the 517 patients with a stable independent gait and normal d-dimer and albumin levels died within 100 days, none died within 30 days of assessment and 12 died within 365 days. Of the remaining 817 patients 66 (8%) died within 100 days. CONCLUSION These findings suggest that normal gait, albumin and d-dimer levels are the most parsimonious way of identifying low risk ED patients.

Abstract
Marek's Disease (MD) is a neoplastic disease of chickens and remains as a chronic infectious disease that threatens the poultry industry. Improving genetic resistance to MD in poultry is an important long-term goal, which would significantly augment the current control measures against MD and eventually reduce the annual economic loss. In this study, survival patterns of F2 birds from 2 reciprocal crosses were compared to examine possible difference in survival between the reciprocal crosses in response to MD virus (MDV) challenge. A total of 246 and 224 F2 chicks derived from reciprocal crosses of lines 63 × 72 and lines 72 × 63, respectively, were sampled from an MDV challenge trial and survival days were recorded from the MDV-inoculation date to the end of experiment. Statistical analyses, including Principal Component Analysis (PCA) followed by a cox-regression model, showed there was no significant difference in survival days between reciprocal crosses (P > 0.05). To the best of our knowledge, this is the first MD survival study on reciprocal crosses of 2 genetically diversified lines of chickens differing in MD resistance. This report documented the experimental evidence that the genetic lineage of grandparental (maternal or paternal) effect on survival days was minimal, if present at all.

Abstract
Background The ROCKET AF (Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation) evaluated rivaroxaban (20/15 mg/d) versus warfarin in patients with atrial fibrillation. A separate trial, J‐ROCKET AF (Japanese ROCKET AF), compared rivaroxaban (15/10 mg/d) and warfarin in Japanese patients with atrial fibrillation. Data about rivaroxaban following J‐ROCKET AF criteria compared with warfarin and ROCKET AF dosage were limited. Methods and Results This retrospective study used medical data from a multicenter healthcare provider in Taiwan that included 3162 patients taking rivaroxaban. Among 2320 patients with an estimated glomerular filtration rate (eGFR) ≥50 mL/min per 1.73 m2, 384 and 1936 patients followed the ROCKET AF (20 mg/d) and J‐ROCKET AF (15 mg/d) recommendation, respectively. Among 842 patients with an eGFR <50 mL/min per 1.73 m2, 422 and 420 patients followed the ROCKET AF (15 mg/d) and J‐ROCKET AF (10 mg/d) recommendation, respectively. A total of 2053 patients with atrial fibrillation receiving warfarin were identified. Rivaroxaban following either ROCKET AF or J‐ROCKET AF dosage criteria was associated with a comparable risk of thromboembolism but a lower risk of bleeding than warfarin. For patients with an eGFR ≥50 mL/min per 1.73 m2, risks of clinical events did not differ significantly between the 2 dosage criteria of rivaroxaban. For patients with an eGFR <50 mL/min per 1.73 m2, the ROCKET AF dosage was associated with a higher risk of major bleeding compared with the J‐ROCKET AF dosage (hazard ratio, 2.70; P=0.0445) without significant differences regarding the risk of ischemic events. Conclusions In Asian patients with atrial fibrillation, the J‐ROCKET AF dosage was as effective as the ROCKET AF dosage irrespective of renal function. The risk of major bleeding was lower with the J‐ROCKET AF dosage in patients with an eGFR <50 mL/min per 1.73 m2. Compared with warfarin, rivaroxaban following either dosage criteria was effective and even safer.

Abstract
Abstract
Background
Recurrent pericarditis (RP) is managed with nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids (CS), and colchicine; up to 15% of pericarditis patients experience multiple recurrences. Interleukin 1 (IL-1) is an important cytokine in the pathophysiology of RP. Rilonacept (KPL-914) is a recombinant fusion protein which binds IL-1α and IL-1β. An ongoing Phase 2 study of rilonacept demonstrated improvements in RP symptoms and inflammation.
Purpose
To evaluate the efficacy and safety of subcutaneous (SC) rilonacept in patients with RP in a Phase 3, randomized, placebo-controlled trial.
Methods
RHAPSODY is a double-blind, placebo-controlled, randomized-withdrawal trial; ∼50 patients will be enrolled (Figure). Patients (≥12 y) must present with at least a third pericarditis episode (all etiologies except infectious and malignant) characterized by a pain score ≥4 on the 11-point Numeric Rating Scale (NRS) and C-reactive protein (CRP) ≥1 mg/dL at screening. Patients may be receiving stable doses of analgesics, NSAIDs, colchicine, and/or CS. After a loading dose (320 mg SC in adults and 4.4 mg/kg SC in children), all patients will receive weekly rilonacept (160 mg SC in adults and 2.2 mg/kg SC in children) during the run-in period. Patients able to taper and discontinue concomitant pericarditis medications and achieve clinical response (mean daily NRS score ≤2.0 during the 7 days before randomization and CRP level ≤0.5 mg/dL) will be randomized 1:1 in a blinded fashion to continued rilonacept or matching placebo weekly SC injections. Investigators may choose different treatments for pericarditis recurrences based on patient clinical status, including bailout rilonacept, while maintaining the blind to prior treatment assignment. The primary efficacy endpoint is time to pericarditis recurrence (adjudicated by an independent committee) in the randomized-withdrawal portion of the study. Secondary efficacy endpoints are the proportion of patients maintaining a clinical response, percentage of days with NRS pain score ≤1, and percentage of patients with no-to-minimal pericarditis symptoms based on patient global assessment. Safety evaluations include adverse events monitoring, physical examinations, and laboratory tests.
Figure 1
Conclusions
RHAPSODY is a pivotal Phase 3 trial evaluating the efficacy and safety of rilonacept in patients with RP using a double-blind, placebo-controlled, randomized-withdrawal design. The results of this study may inform the management of RP.

Abstract
OBJECTIVE To determine the ability of a normal D-dimer level (<0.5 mg/l) to identify emergency department (ED) patients at low risk of 30-day all-cause mortality. DESIGN In this prospective observational study, D-dimer levels of adult medical patients were assessed at arrival to the ED. Data on 30-day survival status were extracted from the Danish Civil Registration System with complete follow-up. SETTING The Hospital of South West Jutland. PATIENTS All patients aged 18 years or older who required any blood sample on a clinical indication on arrival to the ED. Participants were required to give written informed consent before enrollment. MAIN RESULTS The study population of 1 518 patients with median age 66 years of which 49.4% were female. Of the 791 (52.1%) patients with normal D-dimer levels, 3 (0.4%) died within 30 days; one death resulted from an unrelated traumatic accident. Of the 727 (47.9%) patients with abnormal D-dimer levels (≥0.50 mg/l), 32 (4.4%) died within 30 days. Patients with normal D-dimer levels had a significantly lower 30-day mortality compared to patients with abnormal D-dimer levels (odds ratio 0.08, 95% CI 0.02-0.28): of the 35 patients who died within 30 days, 19 (54.3%) had normal or near normal vital signs when first assessed. CONCLUSION Normal D-dimer levels identified patients at low risk of 30-day mortality. Since most patients who died within 30 days presented with normal or near normal vital signs, D-dimer levels appear to provide additional prognostic information.

Abstract
Inclusion body hepatitis-hydropericardium syndrome (IBH-HPS) caused by fowl adenovirus type 4 (FAdV-4) has caused huge economic losses for China in the past five years. At present, this disease is controlled in many flocks with the inactivated FAdV vaccine, but the offspring chicks of a layer breeding flock that were vaccinated with this vaccine still became infected and developed IBH-HPS with a 20% mortality rate. Analysis revealed that the NDV-attenuated vaccine in use from the above-mentioned poultry farm was simultaneously contaminated with FAdV-4 and chicken infectious anemia virus (CIAV). The FAdV and CIAV isolated from the vaccine were purified for the artificial preparation of an NDV-attenuated vaccine singly contaminated with FAdV or CIAV, or simultaneously contaminated with both of them. Seven-day-old layers with maternal FAdV antibody were inoculated with the artificially prepared, contaminated vaccines and assessed for corresponding indices. The experiments showed that no obvious symptoms occurred after using the NDV-attenuated vaccine singly contaminated with FAdV or CIAV; however, common IBH and occasional HPS-related death was found in birds after administering the NDV-attenuated vaccine co-contaminated with FAdV and CIAV. In conclusion, this study illustrated that CIAV could assist FAdV in breaking maternal FAdV antibody protection, which then caused the IBH-HPS after vaccination with the co-contaminated NDV vaccine.

Abstract
Abstract
Cell-free DNA (cfDNA), as a non-invasive strategy, provides substantial benefit to overcome tumor heterogeneity. Surveillance of recurrence after standard treatment in early breast cancer (BC) using cfDNA, enables to detect minimal residual disease (MRD), also to identify genomic alterations driving recurrences. We aimed to assess the role of cfDNA in detecting MRD by investigating genomic alterations of 1)primary, recurred tumor and 2)cfDNA at time of recurrence using deep targeted sequencing. Fifty-four early BC patients were enrolled prospectively between 2014 and 2017 at time of recurrence. Median disease free interval was 28.5 months (rage 6.2-49.8). 62.7% (32/51) were hormone receptor (HR) positive (28 HRpos/HER2neg, 4 HRpos/HER2pos), 11.8% (6/51) were HRneg/HER2pos and 25.5% (13/51) were triple negative BCs. 59.3% (32/54) patients developed loco-regional recurrence (15 local recurrence only, 13 regional only, 4 with both) and distant metastasis was observed among 40.7% (22/54) patients. Cell-free DNA was extracted from 5cc blood at time of recurrence. Deep targeted sequencing was performed using customized NGS panel –encompassing 426 cancer-related target coding region, 242 fusion and amplification-related region- of cfDNA and FFPE(formalin fixed paraffin embedded) tumor samples archived from surgical resection or biopsy. Deep targeted sequencing data was successfully performed in 72.1% (31/43) plasma samples and sequencing yield was significantly lower when stored for more than 2yrs (46.2% vs 83.3%).
Mutations of cfDNA and tumor (primary, recurred) were analyzed. Mean sequencing depth of cfDNA and FFPE were x425.7 and x777.6 respectively. Median number of pathogenic mutations found in primary tumor, cfDNA and recurred tumor were 27(range 12-99), 25(range 8-85) and 9(range 0-23). Among mutations found in primary tumor, 27.4% were shared mutations (range 8.1%-72.7%) with recurred tumor and 26.1% were shared mutations (range 4.7%-69.2%) observed in cfDNA sample. Among mutations found in recurred tumor, 40.9% were observed in cfDNA (range 17.7-87.5%). In primary tumor, median number of mutations with allelic fraction (MAF)>10% were 12 (range 4-21) and at least one mutation was found in cfDNA at time of recurrence. Among mutations with MAF>10%, 59.4% and 69.1% were found in cfDNA and recurred tumor. Known oncogenic mutations of PIK3CA, TP53, GATA3, AKT1, ESR1, RELN, ERBB2, ERBB3, BRCA1 mutation were found. PIK3CA gene (p.H1047R) was found in two cases both in primary tumor and cfDNA at recurrence (MAF 11.4% vs 5.3% and 12.3% vs 15.4%) suggesting de novo driver mutation. One patient developed regional recurrence during adjuvant aromatase inhibitor with ESR1 V392I mutation in both cfDNA and recurred tumor (MAF 48.1 and 54.5%), while another patient's recurred tumor during aromatase inhibitor harbored ESR1 D538G mutation exclusively in recurred tumor with MAF <1%. Both patients had no ESR1 hotpot mutation in primary tumor.
Our data showed sequencing yield of 83.3% in plasma samples within 2yr. Pathogenic mutations in primary tumor, especially when MAF>10%, half of them was observed in cfDNA at time of recurrence. ESR1 mutation should be included in cfDNA surveillance for patients undergoing endocrine therapy even absent in primary tumor.

Abstract
Abstract
Introduction: Involvement of peripheral nerves in the experimental model of multiple sclerosis (MS) is rarely observed. The objective of this study was to investigate the changes in the locomotion in a mouse model of experimental autoimmune encephalomyelitis (EAE) and correlate with histological changes, if any, in the sections of sciatic nerve and lumbar part of spinal cord. Material and Methods: C57BL/6 mice (10 weeks, n = 8) were immunized with single subcutaneous injection of 300 μg of MOG35-55 and 200 μL of complete Freund's adjuvant (CFA) to produce EAE models. Limp tail with weakness of hindlimb was observed on day 10 and improvement in the weakness was observed on day 20 onwards. Footprint analysis was done to evaluate the impairment in the locomotion on day 0, 5, 10, 15 and 20 of the experiment. Results: One way repeated measure ANOVA found significant reduction in the mean hindlimb stride length on day 10 and 15 (left) and on day 15 and day 20 (right) when compared to mean stride length in day 0 (p<0.05). Histological analysis showed evidence of macrophage infiltration around the dilated blood vessels in the epineurium of sciatic nerve and evidence of damage in the myelinated white matter of lateral funiculus of the lumbar sections of the spinal cord in EAE mice. Conclusion: It is concluded that in mouse model of EAE, the impairment oflocomotion due to damage in the lumbar part of spinal cord can be associated with inflammatory changes in the sciatic nerve.

Abstract
The breakdown of the polymeric component of contemporary composite dental restorative materials compromises their longevity, while leachable compounds from these materials have cellular consequences. Thus, a new generation of composite materials needed to be designed to have a longer service life and ensure that any leachable compounds are not harmful to appropriate cell lines. To accomplish this, we have developed concurrent thiol-ene-based polymerization and allyl sulfide-based addition-fragmentation chain transfer chemistries to afford cross-linked polymeric resins that demonstrate low shrinkage and low shrinkage stress. In the past, the filler used in dental composites mainly consisted of glass, which is biologically inert. In several of our prototype composites, we introduced fluorapatite (FA) crystals, which resemble enamel crystals and are bioactive. These novel prototype composites were benchmarked against similarly filled methacrylate-based bisphenol A diglycidyl ether dimethacrylate / triethylene glycol dimethacrylate (bisGMA/TEGDMA) composite for their cytotoxicity, mechanical properties, biofilm formation, and fluoride release. The leachables at pH 7 from all the composites were nontoxic to dental pulp stem cells. There was a trend toward an increase in total toughness of the glass-only-filled prototype composites as compared with the similarly filled bisGMA/TEGDMA composite. Other mechanical properties of the glass-only-filled prototype composites were comparable to the similarly filled bisGMA/TEGDMA composite. Incorporation of the FA reduced the mechanical properties of the prototype and bisGMA/TEGDMA composite. Biofilm mass and colony-forming units per milliliter were reduced on the glass-only-filled prototype composites as compared with the glass-only-filled bisGMA/TEGDMA composite and were significantly reduced by the addition of FA to all composites. Fluoride release at pH 7 was greatest after 24 h for the bisGMA/TEGDMA glass + FA composite as compared with the similarly filled prototypes, but overall the F- release was marginal and not at a concentration to affect bacterial metabolism.

Abstract
Background Patients with impaired liver function ( ILF ) were excluded from clinical trials that investigated non-vitamin K antagonist oral anticoagulants ( NOAC s) for stroke prevention in patients with atrial fibrillation. The aim of this study was to evaluate the efficacy and safety of NOAC s in atrial fibrillation patients with ILF . Methods and Results A cohort study based on electronic medical records was conducted from 2009 to 2016 at a multicenter healthcare provider in Taiwan and included 6451 anticoagulated atrial fibrillation patients (aged 76.7±7.0 years, 52.5% male). Patients were classified into 2 subgroups: patients with normal liver function (n=5818) and patients with ILF (n=633, 9.8%). Cox regression analysis was performed to investigate the risks of thromboembolism, bleeding, and death associated with use of NOAC s and warfarin in patients with normal liver function and ILF , respectively. In patients with normal liver function, compared with warfarin therapy (n=2928), NOAC therapy (n=4048) was associated with significantly lower risks of stroke or systemic embolism (adjusted hazard ratio: 0.75; 95% confidence interval, 0.65-0.88; P<0.001) and death (adjusted hazard ratio: 0.69; 95% confidence interval, 0.60-0.80; P<0.001) with no difference in major bleeding or gastrointestinal bleeding. In patients with ILF , compared with warfarin therapy (n=394), NOAC therapy (n=342) was associated with significantly lower risk of death (adjusted hazard ratio: 0.64; 95% confidence interval, 0.49-0.83; P<0.001), but no difference in stroke or systemic embolism, major bleeding, or gastrointestinal bleeding. Conclusions In atrial fibrillation patients with ILF , NOAC therapy and warfarin therapy were associated with similar risks of stroke or systemic embolism, major bleeding, and gastrointestinal bleeding.

Abstract
Mithun (Bos frontalis) is a unique domestic free range bovine species of North Eastern hilly regions of India. The present study was designed to assess the seasonal effect of slow release exogenous melatonin (MT) implant on semen quality parameters (SQP) and in vitro zona binding ability (IVZ) of spermatozoa. The experimental animals were divided into Gr I: Control (n = 5) and Gr II: Treatment (n = 5; melatonin implant @ 18mg/50 kg bwt). A total of 20 semen samples/group in winter, spring, autumn and summer seasons (n = 160), twice per week were collected. Following cryopreservation, samples were evaluated for motility parameters (forward progressive, mobility & velocity by computer assisted sperm analyser (CASA), viability, acrosome integrity, plasma membrane and nuclear abnormality, functional status of mitochondria, enzymatic, antioxidant and oxidative profiles, and IVZ. The study revealed significant (p < 0.05) improvement in total motility, viability, acrosome-, plasma membrane-, and nuclear-integrity, and antioxidant profiles; with highest values in spring and lowest in summer season in the fresh semen in Gr II than the Control. A significant (p < 0.05) improvement in motility parameters, membrane potential of mitochondria, antioxidant profiles and reduction in sperm and nuclear abnormalities, leakage of intracellular enzymes and oxidative stress and IVZ index & binding percentage in post-thaw semen samples in melatonin supplemented than in un-supplemented control group was observed. It can be concluded from the study that slow-release melatonin supplementation can be effectively utilized to improve the antioxidant profiles and reduction of oxidative stress, with cascading beneficial effects on semen quality parameters and fertility status of the mithun bull.

Abstract
Objective: To investigate the association between alcohol consumption and lung cancer risk in Chinese males. Methods: Information on alcohol consumption and outcomes were collected on a biennial basis among males in Kailuan Cohort (2006-2015). In addition, electronic databases of hospitals affiliated to Kailuan Community, Insurance Systems of Kailuan Community and Tangshan were also used for supplementary information retrieval. Cox proportional hazards regression models were used to evaluate the hazard ratio (HR) and 95%CI of baseline frequency and type of alcohol consumption associated with lung cancer risk in males. Non-drinkers were used as control group. Results: A total of 101 751 males were included and 913 new lung cancer cases were identified in the Kailuan male cohort study, with a total follow-up time of 808 146.56 person-years and a median follow-up time of 8.88 years by 31 December 2015. After adjusting for potential confounding factors, the HR of former drinkers, occasional drinkers (<1/day) and drinkers (≥1/day) were 1.30 (95%CI: 0.90-1.88), 0.80 (95%CI: 0.64-1.01) and 1.04 (95%CI: 0.85-1.27), respectively, compared with non-drinkers. In addition, drinking beer/red wine (HR=0.91, 95%CI: 0.69-1.20) and white wine (HR=0.99, 95%CI: 0.83-1.19) showed no significant association with lung cancer. The results were similar when stratified analysis were conducted. Conclusion: Our study results don't support the hypothesis that alcohol consumption is significantly associated with the risk of lung cancer in males.
