BACKGROUND: The low incidence of Mycobacterium tuberculosis infection and lack of adequate controls have prevented researchers from estimating tuberculosis (TB) risk in inflammatory bowel disease (IBD) patients. AIM: To evaluate the risk of incident TB among IBD patients. METHODS: Using the 2011-2013 data of the South Korean National Health Insurance (NHI) system, we calculated the incidence rates (IRs), standardised incidence ratio (SIR) and number needed to screen (NNS) for incident TB in IBD patients compared to the general population in terms of subtype, age, gender and IBD medications...

To study epigenetic inheritance, yeast silent heterochromatin provides an excellent model. Previously, we developed an in vitro assembly system to demonstrate the formation of filament structures with requirements that mirror yeast epigenetic gene silencing in vivo However, the properties of these filaments have not been investigated in detail. Here, we show that the assembly system requires Sir2, Sir3, Sir4, nucleosomes and O-acetyl-ADP-ribose. We also demonstrate that all Sir proteins and nucleosomes are components of these filaments to prove they are SIR-nucleosome filaments...

Early diagnosis of bacteremia for patients with suspected sepsis is 1 way to improve prognosis of sepsis. Systemic inflammatory response syndrome (SIRS) has long been utilized as a screening tool to detect bacteremia by front-line healthcare providers. The value of SIRS to predict bacteremia in elderly patients (≥65 years) with suspected sepsis has not yet been examined in emergency departments (EDs).We aimed to evaluate the performance of SIRS components in predicting bacteremia among elderly patients in EDs...

To evaluate the incidence of a subsequent primary thyroid malignancy in patients with an index head and neck squamous cell carcinoma (HNSCC), we analyzed the National Cancer Institute's Surveillance, Epidemiology, and End Results database to identify a cohort of patients who had been diagnosed with a primary HNSCC from 1973 through 2004. The study population was made up of 60,323 patients of all ages, roughly three-quarters of whom were male. A total of 60 patients (0.1%) developed a subsequent thyroid malignancy-not a statistically significant finding...

BACKGROUND: Systemic inflammatory response syndrome (SIRS) is frequent after cardiac surgery, but data on its incidence and perioperative risk factors are scarce for children with congenital heart disease. METHODS: SIRS incidence within 72 hours following cardiac surgery was evaluated in a secondary analysis of children enrolled to a treatment-free control group of a randomized controlled trial. Intraoperative parameters were investigated for their association with SIRS using multivariable fractional polynomial logistic regression models...

Hongzhi Wang, Ming Zhao, Jerome L Ackerman, Yiqiao Song
Spin-lattice relaxation (T1) has always been measured by inversion-recovery (IR), saturation-recovery (SR), or related methods. These existing methods share a common behavior in that the function describing T1 sensitivity is the exponential, e.g., exp(-τ/T1), where τ is the recovery time. In this paper, we describe a saturation-inversion-recovery (SIR) sequence for T1 measurement with considerably sharper T1-dependence than those of the IR and SR sequences, and demonstrate it experimentally. The SIR method could be useful in improving the contrast between regions of differing T1 in T1-weighted MRI...

Sulfobacillus acidophilus TPY, isolated from a hydrothermal vent in the Pacific Ocean, is a moderately thermoacidophilic Gram-positive bacterium that can oxidize ferrous iron or sulfur compounds to obtain energy. In this study, comparative transcriptomic analyses of S. acidophilus TPY were performed under different redox conditions. Based on these results, pathways involved in sulfur metabolism were proposed. Additional evidence was obtained by analyzing mRNA abundance of selected genes involved in the sulfur metabolism of sulfur oxygenase reductase (SOR)-overexpressed S...

Thomas W Carr
In an SIRS compartment model for a disease we consider the effect of different probability distributions for remaining immune. We show that to first approximation the first three moments of the corresponding probability densities are sufficient to well describe oscillatory solutions corresponding to recurrent epidemics. Specifically, increasing the fraction who lose immunity, increasing the mean immunity time, and decreasing the heterogeneity of the population all favor the onset of epidemics and increase their severity...

OBJECTIVE The neurological prognostic score (NPS) was recently proposed as a means for predicting neurological outcomes, such as the preservation of neurological function and the prevention of neurological death, in brain metastasis patients treated with Gamma Knife radiosurgery (GKRS). NPS consists of 2 groups: Group A patients were expected to have better neurological outcomes, and Group B patients were expected to have poorer outcomes. NPS robustness was tested in various situations. METHODS In total, 3040 patients with brain metastases that were treated with GKRS were analyzed...

Genes adjacent to telomeres are subject to transcriptional repression mediated by an integrated set of chromatin modifying and remodeling factors. The telomeres of Saccharomyces cerevisiae have served as a model for dissecting the function of diverse chromatin proteins in gene silencing, and their study has revealed overlapping roles for many chromatin proteins in either promoting or antagonizing gene repression. The H3K4 methyltransferase Set1, which is commonly linked to transcriptional activation, has been implicated in telomere silencing...

OBJECTIVE: Recent studies indicate increased cardiovascular (CV) morbidity and mortality in patients with psoriatic arthritis (PsA), but results are inconsistent. This prompted our investigation of the mortality rate, cause of death, and incidence of acute CV events in patients from northern Sweden with PsA. METHODS: Patients with established PsA (464) were included. To calculate standardized mortality ratio (SMR) and standardized incidence ratio (SIR) for CV events, data were extracted from the National Causes of Death Register and the National Inpatient Care Register in Sweden, and compared with the general population...

Data on sepsis prevalence on the general wards is lacking on the UK and in the developed world. We conducted a multicentre, prospective, observational study of the prevalence of patients with sepsis or severe sepsis on the general wards and Emergency Departments (ED) in Wales. During the 24-hour study period all patients with NEWS≥3 were screened for presence of 2 or more SIRS criteria. To be eligible for inclusion, patients had to have a high clinical suspicion of an infection, together with a systemic inflammatory response (sepsis) and evidence of acute organ dysfunction and/or shock (severe sepsis)...

OBJECTIVES: Patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) treated with cyclophosphamide have an increased malignancy risk compared with the general population. We investigated whether treatment with rituximab instead of cyclophosphamide has decreased the malignancy risk in patients with AAV. METHODS: The study included patients with AAV treated at a tertiary vasculitis referral centre between 2000 and 2014. The malignancy incidence in these patients was compared with the incidence in the general population by calculating standardised incidence ratios (SIRs), adjusted for sex, age and calendar year...

The objective of the present study was to systematically assess the association between dioxin/2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and cancer incidence and mortality. Systematic literature searches were conducted until July 2015 in Pubmed, Embase and Cochrane library to identify relevant studies. A random-effects model was applied to estimate the pooled odds ratio (OR), risk ratio (RR), standard incidence ratio (SIR) or standard mortality ratio (SMR) for cancer incidence or mortality. In addition, dose-response, meta-regression, subgroup, and publication bias analyses were conducted...

As the number of long-term cervical cancer survivors continues to increase because of improvements in treatment, concerns about second primary malignancy have grown. The high-risk area of second primary cancers in cervical cancer survivors is the pelvis. Pelvic inflammatory disease (PID) could be a useful marker for gynecological cancers. Thus, we designed a large-scale, nationwide, controlled cohort study to investigate whether PID or other risk factors increased the risk of second primary cancers in patients with cervical cancer treated by surgery alone...

INTRODUCTION: Percutaneous cholecystostomy (PC) is often performed for patients with acute cholecystitis who are at high risk for operative morbidity and mortality. However, the necessity for routine cholangiography following PC remains unclear. We hypothesized that routine surveillance cholangiography (RSC) following PC would provide no benefit compared to on-demand cholangiography (ODC) triggered by signs or symptoms of biliary pathology. METHODS: We performed a three-year retrospective cohort analysis of patients managed with PC for acute cholecystitis at two tertiary care hospitals...
