Gamma Glutamyltransferase Reduction Is Associated With Favorable Outcomes in Pediatric Primary Sclerosing Cholangitis.

Adverse clinical events in primary sclerosing cholangitis (PSC) happen too slowly to capture during clinical trials. Surrogate endpoints are needed, but no such validated endpoints exist for children with PSC. We evaluated the association between gamma glutamyltransferase (GGT) reduction and long-term outcomes in pediatric PSC patients.

Frailty and Outcomes After Myocardial Infarction: Insights From the CONCORDANCE Registry.

Background Little is known about the prognostic implications of frailty, a state of susceptibility to stressors and poor recovery to homeostasis in older people, after myocardial infarction ( MI ). Methods and Results We studied 3944 MI patients aged ≥65 years treated at 41 Australian hospitals from 2009 to 2016 in the CONCORDANCE ( Australian Cooperative National Registry of Acute Coronary Care, Guideline Adherence and Clinical Events ) registry. Frailty index ( FI ) was determined using the health deficit accumulation method.

A Survey of Molecular Heterogeneity in Hepatocellular Carcinoma.

Understanding the heterogeneity of dysregulated pathways associated with the development of hepatocellular carcinoma (HCC) may provide prognostic and therapeutic avenues for disease management. As HCC involves a complex process of genetic and epigenetic modifications, we evaluated expression of both polyadenylated transcripts and microRNAs from HCC and liver samples derived from two cohorts of patients undergoing either partial hepatic resection or liver transplantation. Copy number variants were inferred from whole genome low-pass sequencing data, and a set of 56 cancer-related genes were screened using an oncology panel assay.

In-depth molecular profiling of the biphasic components of uterine carcinosarcomas.

Uterine carcinosarcoma is a clinically aggressive malignancy composed of a mix of carcinomatous and sarcomatous elements. We performed targeted next-generation sequencing of 27 uterine cancer and sarcoma genes together with immunohistochemical analyses of selected proteins in 30 uterine carcinosarcomas. This included 13 cases in which the distinct carcinoma and sarcoma components were sequenced separately and 10 cases where the metastatic tumours were analysed in addition to the primary tumours.

Diet composition as a source of variation in experimental animal models of cancer cachexia.

Background: A variety of experimental animal models are used extensively to study mechanisms underlying cancer cachexia, and to identify potential treatments. The important potential confounding effect of dietary composition and intake used in many preclinical studies of cancer cachexia is frequently overlooked. Dietary designs applied in experimental studies should maximize the applicability to human cancer cachexia, meeting the essential requirements of the species used in the study, matched between treatment and control groups as well as also being generally similar to human consumption.

Understanding the dynamics of monomeric, dimeric, and tetrameric α-synuclein structures in water.

Human α-synuclein (αS) is an intrinsically disordered protein associated with Parkinson's disease. Molecular mechanisms of corruptive misfolding and aggregation of αS resulting in the disease, as well as the structure and other properties of the corresponding oligomers are not entirely understood yet, preventing the development of efficient therapies. In this study, we investigate the folding dynamics of initially unfolded hypothetical αS constructs in water using all-atom molecular dynamics simulations.

Patients' blood pressure knowledge, perceptions and monitoring practices in community pharmacies.

Unlabelled: Hypertension is a modifiable risk factor for cardiovascular disease. Despite this, patients often cannot or inaccurately estimate their risk factors.

Objectives: IN ORDER TO IMPROVE PHARMACIST INTERVENTIONS, WE SOUGHT TO: 1) find out patients' knowledge about blood pressure (BP) and their self-monitoring behaviors and 2) identify the relationships between these two elements.

Tonometry to estimate intestinal perfusion in newborn piglets.

Aim: To determine the correlation between gastric intramucosal pH and superior mesenteric artery (SMA) flow in newborn piglets.

Methods: Fourteen newborn piglets were randomly assigned to either a control or to an epinephrine group which received 0,1,2,4,0 microg/kg/min of epinephrine for 60 minutes, each dose. Gastric tonometry was performed, SMA flow was measured, and intramucosal pH and the ratio of tonometer pCO(2) over arterial pCO(2) (rCO(2)) were calculated.
