Abstract
With advances in target therapy, molecular analysis of tumors is routinely required for treatment decisions in patients with advanced non-small cell lung cancer (NSCLC). Liquid biopsy refers to the sampling and analysis of circulating cell-free tumor DNA (ctDNA) in various body fluids, primarily blood. Because the technique is minimally invasive, liquid biopsies are the future in cancer management. Epidermal growth factor receptor (EGFR) ctDNA tests have been performed in routine clinical practice in advanced NSCLC patients to guide tyrosine kinase inhibitor treatment. In the near future, liquid biopsy will be a crucial prognostic, predictive, and diagnostic method in NSCLC. Here we present the current status and future perspectives of liquid biopsy in NSCLC.

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 Assessment of programmed cell death-ligand 1 (PD-L1) immunohistochemical staining is used for treatment decisions in non-small cell lung cancer (NSCLC) regarding use of PD-L1/programmed cell death protein 1 (PD-1) immunotherapy. The reliability of the PD-L1 22C3 pharmDx assay is critical in guiding clinical practice. The Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists investigated the interobserver reproducibility of PD-L1 staining with 22C3 pharmDx in NSCLC samples. Methods Twenty-seven pathologists individually assessed the tumor proportion score (TPS) for 107 NSCLC samples. Each case was divided into three levels based on TPS: <1%, 1%–49%, and ≥50%. Results The intraclass correlation coefficient for TPS was 0.902±0.058. Weighted κ coefficient for 3-step assessment was 0.748±0.093. The κ coefficients for 1% and 50% cut-offs were 0.633 and 0.834, respectively. There was a significant association between interobserver reproducibility and experience (formal PD-L1 training, more experience for PD-L1 assessment, and longer practice duration on surgical pathology), histologic subtype, and specimen type. Conclusions Our results indicate that PD-L1 immunohistochemical staining provides a reproducible basis for decisions on anti–PD-1 therapy in NSCLC.

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.

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.
