BACKGROUND: Decreased binding capacity of SERT in the prefrontal cortex has been observed in both suicide victims and suicide attempters. Moreover, some studies have shown that SERT has a seasonal variation with lower binding capacity in the spring and summer, which coincides with a seasonal peak of suicides. Our aim was to explore whether the season of treatment initiation with antidepressants is associated with suicide or suicide attempt and compare it with the underlying suicide seasonality in the general population...

We describe a relatively simple stochastic model of Ebola transmission that was used to produce forecasts with the lowest mean absolute error among Ebola Forecasting Challenge participants. The model enabled prediction of peak incidence, the timing of this peak, and final size of the outbreak. The underlying discrete-time compartmental model used a time-varying reproductive rate modeled as a multiplicative random walk driven by the number of infectious individuals. This structure generalizes traditional Susceptible-Infected-Recovered (SIR) disease modeling approaches and allows for the flexible consideration of outbreaks with complex trajectories of disease dynamics...

BACKGROUND: The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) Task Force recently introduced a new clinical score termed quick Sequential (Sepsis-related) Organ Failure Assessment (qSOFA) for identification of patients at risk of sepsis outside the intensive care unit (ICU). We attempted to compare the discriminatory capacity of the qSOFA versus the Systemic Inflammatory Response Syndrome (SIRS) score for predicting mortality, ICU-free days, and organ dysfunction-free days in patients with suspicion of infection outside the ICU...

It is difficult to differentiate Pneumocystis pneumonia (PCP) from rituximab-induced interstitial lung disease (RILD) in lymphoma patients with diffuse pulmonary infiltrates who are receiving rituximab-containing chemotherapy. Using a clinical scoring system, we aim to differentiate PCP from RILD who are receiving rituximab-containing chemotherapy. We reviewed the medical records of lymphoma patients who had received rituximab-containing chemotherapy between 2012 and 2015 in a tertiary hospital. Among 613 lymphoma patients receiving rituximab-containing chemotherapy, 97 (16%) had diffuse pulmonary infiltrates...

BACKGROUND: Thyroid cancer (TC) is the most common endocrine malignancy. TC patients have a good prognosis and a low disease-related mortality rate. Since the patients are often young, they may be at a higher risk for a second primary malignancy (SPM). We sought to determine the incidence, risk and types of SPM between 1980-2011, and to assess SPM trends over time among Israeli TC patients. METHODS: Data were derived from the Israel National Cancer Registry. Primary TC patients diagnosed during 1980-2009 were followed-up for SPM incidence until December 31, 2011...

Ultraviolet light (UV) causes DNA damage that is removed by nucleotide excision repair (NER). UV-induced DNA lesions must be recognized and repaired in nucleosomal DNA, higher order structures of chromatin and within different nuclear sub-compartments. Telomeric DNA is made of short tandem repeats located at the ends of chromosomes and their maintenance is critical to prevent genome instability. In Saccharomyces cerevisiae the chromatin structure of natural telomeres is distinctive and contingent to telomeric DNA sequences...

INTRODUCTION: Acute pancreatitis (AP) is an emerging problem in pediatrics, with most cases resolving spontaneously. However, approximately 10-30% are believed to develop "severe acute pancreatitis" (SAP). METHODS: This consensus statement on the classification of AP in pediatrics was developed through a working group that performed an evidence-based search for classification of AP in adult pancreatitis, definitions and criteria of Systemic Inflammatory Response Syndrome (SIRS), and organ failure in pediatrics...

Background and Aims: The association between inflammatory bowel disease (IBD) and cancer remains poorly defined in Asian populations. Therefore, we conducted a nationwide population-based study to determine the cancer risk in Korean patients with IBD. Methods: Using the National Health Insurance claims data, we collected data on patients diagnosed with IBD (5,595 Crohn's disease [CD] and 10,049 ulcerative colitis [UC]) from 2011 to 2014. Standardized incidence ratios (SIRs) of overall and site-specific cancers in IBD patients in comparison with the general population were calculated...

This study aimed to compare the clinical outcomes and hospitalization cost between early enteral nutrition (EEN) and parenteral nutrition (PN) after resection of esophageal cancer. A total of 79 patients with esophageal cancer who underwent surgical treatment in our hospital from July 2010 to July 2013 were enrolled in this study. They were divided into EEN group (n = 39) and PN group (n = 40) based on the nutrition support modes. The clinical factors such as time to first fecal passage, postoperative albumin infusion, differences of serum albumin value, hospital stay, systematic inflammatory response syndrome (SIRS) duration, complications, initial hospitalization cost, and mortality were retrospectively compared...

BACKGROUND The National Healthcare Safety Network (NHSN) catheter-associated urinary tract infection (CAUTI) definition was revised as of January 2015 to exclude funguria and lower bacteriuria levels. We evaluated the effect of the CAUTI definition change on NHSN-defined central-line-associated bloodstream infection (CLABSI) outcomes. METHODS We compared CAUTI and CLABSI NHSN-defined outcomes for calendar years 2014 and 2015 in the adult intensive care units (ICUs) of a single large health system. Changes in the event rates, the associated organisms, and the standardized infection ratio (SIR) were evaluated...

BACKGROUND: Cancer is a growing problem in persons living with HIV infection (PLWH) and hepatitis C virus (HCV) coinfection could play an additional role in carcinogenesis. Herein, all cancers in an HIV-mono and HIV/HCV-coinfected cohort were evaluated and compared to identify any differences between these two populations. METHODS: A retrospective cohort study was conducted including all cancers in PLWH between 1993 and 2014. Cancers were classified in two groups, AIDS-defining cancer (ADC) and non AIDS-defining cancer (NADC)...

We prove almost sure exponential stability for the disease-free equilibrium of a stochastic differential equations model of an SIR epidemic with vaccination. The model allows for vertical transmission. The stochastic perturbation is associated with the force of infection and is such that the total population size remains constant in time. We prove almost sure positivity of solutions. The main result concerns especially the smaller values of the diffusion parameter, and describes the stability in terms of an analogue [Formula: see text] of the basic reproduction number [Formula: see text] of the underlying deterministic model, with [Formula: see text]...

BACKGROUND: The best predictors of short- and medium-term mortality of cirrhotic patients receiving intensive care support are unknown. METHODS: We conducted meta-analyses from 13 studies (2523 cirrhotics) after selection of original articles and response to a standardized questionnaire by the corresponding authors. End-points were in-ICU, in-hospital, and 6-month mortality in ICU survivors. A total of 301 pooled analyses, including 95 analyses restricted to 6-month mortality among ICU survivors, were conducted considering 249 variables (including reason for admission, organ replacement therapy, and composite prognostic scores)...

BACKGROUND: Kidney transplant recipients (KTR) are known to have a higher risk of cancer than the general population, especially of malignancies related to oncogenic viral infections. This study assessed the incidence of de novo malignancies (DNMs) in patients receiving kidney transplantation and in dialysis patients (DP) on the waiting list for transplantation at the same centre. The aim was to quantify the contribution of post-transplant immunosuppression to the underlying risk of developing a DNM in dialysis patients on the waiting list for kidney transplant...

Runkuan Yang, Jyrki Tenhunen, Tor Inge Tonnessen
Severe acute pancreatitis (SAP) starts as a local inflammation of pancreatic tissue that induces the development of multiple extrapancreatic organs dysfunction; however, the underlying mechanisms are still not clear. Ischemia-reperfusion, circulating inflammatory cytokines, and possible bile cytokines significantly contribute to gut mucosal injury and intestinal bacterial translocation (BT) during SAP. Circulating HMGB1 level is significantly increased in SAP patients and HMGB1 is an important factor that mediates (at least partly) gut BT during SAP...

The influence of routine guarana (Paullinia cupana) consumption on apparent tolerance to mercury intoxication has been proposed. The present study investigated this hypothesis in Caenorhabditis elegans, a suitable experimental model for studies in toxicology. Wild type (WT) and skn-1 (ok2315) worm strains were pretreated with guarana ethanolic extract (GEE) from larvae 1 (L1) to L4 stage and then exposed for 6 hours to methylmercury (MeHg). The analyses included evaluation of GEE's effects on lethality, developmental delay, feeding, locomotion, gene expression (sod-3, gst-4, sir-2...
