Longitudinal association of statin treatment with insulin sensitivity and beta-cell function in the PROMISE cohort.

Context: Statin treatment lowers low-density lipoprotein (LDL) cholesterol thereby reducing cardiovascular risk. Meta-analyses of clinical trials report a higher risk of new-onset type 2 diabetes with statins. Current clinical evidence regarding effects of statins on insulin sensitivity and beta-cell function is limited.

The FBXO45-GEF-H1 axis controls germinal center formation and B-cell lymphomagenesis.

The role of ubiquitin-mediated degradation mechanisms in the pathogenesis of diffuse large B cell (DLBCL) and follicular lymphoma (FL) is not completely understood. We show that conditional deletion of the E3 ubiquitin ligase Fbxo45 in germinal center B-cells results in B-cell lymphomagenesis in homozygous (100%) and heterozygous (48%) mice. Mechanistically, FBXO45 targets the RHO guanine exchange factor ARHGEF2/GEF-H1 for ubiquitin-mediated degradation.

PHARAOH: A collaborative crowdsourcing platform for phenotyping and regional analysis of histology.

Deep learning has proven capable of automating key aspects of histopathologic analysis.

Here, we present an online collaborative platform that streamlines tissue image annotation to promote the development and sharing of custom computer vision models for PHenotyping And Regional Analysis Of Histology (PHARAOH; https://www.

Decreasing Hospital-acquired Pressure Injuries During the COVID-19 Pandemic: A 5-step Quality Improvement Approach.

Background: Hospital-acquired pressure injuries (HAPIs) are common adverse events with large burdens on patients and health systems. In 2020, during the initial waves of the COVID-19 pandemic, the incidence of admitted patients with HAPIs of stage II and above in our health system rose from 2.92% to 3.

Focus on the Forgotten Organelle: Regulation of Lysosomes in Skeletal Muscle.

Research on the role of the lysosome as the terminal organelle in autophagy and in communicating with other organelles in skeletal muscle is in its infancy. We hypothesize that the lysosome can adapt positively to exercise to improve the clearance of cargo, like dysfunctional mitochondria, within muscle, representing an important therapy for protein homeostasis in aging and muscle disuse.

Sleep disturbance and menopause.

Purpose Of Review: Sleep problems are among the most prevalent and bothersome symptoms of menopause. This review characterizes menopausal sleep disturbances, describes biopsychosocial predictors, and summarizes the evidence supporting pharmacological and nonpharmacological treatment options.

Recent Findings: Recent studies found that sleep changes are early indicators of perimenopause and sought to disentangle the respective impacts of menopausal status, hot flashes (HFs), and changes in reproductive hormones on peri-/postmenopausal sleep problems.

Altered brain dynamics of facial emotion processing in schizophrenia: a combined EEG/fMRI study.

Facial stimuli are relevant social cues for humans and essential signals for adequate social interaction. Impairments in face processing are well-documented in schizophrenia and linked to symptomatology, yet the underlying neural dynamics remain unclear. Here, we investigated the processing and underlying neural temporal dynamics of task-irrelevant emotional face stimuli using combined EEG/fMRI in 14 individuals with schizophrenia and 14 matched healthy controls.

Building knowledge to improve access to inclusive and equitable care for trans and gender-diverse survivors of sexual assault and intimate partner violence: a qualitative research protocol.

Introduction: Intimate partner violence (IPV) and sexual assault are pervasive public health and human rights concerns that disproportionately impact trans and gender-diverse (TGD) individuals. Experiences of cisgenderism and transphobia, compounded by racism and other forms of discrimination and structural violence, can hinder access to appropriate supports in a safe and non-stigmatising environment across a variety of sectors, including but not limited to healthcare, social services, criminal justice, and legal. TGD individuals may also have unique health and social needs requiring support that is not yet in place.

Patient preferences for drug therapy in inflammatory arthritis: protocol for a living systematic review and evidence map to inform clinical practice guidelines.

Introduction: The pharmacological management of inflammatory arthritis often requires choices that involve trade-offs between benefits, risks and other attributes such as administration route, frequency and cost. This living systematic review aims to inform international clinical guidelines on inflammatory arthritis by creating an evidence map of patient preference studies concerning the trade-offs in pharmacological management of inflammatory arthritis.

Methods And Analysis: We will include published and peer-reviewed full-text studies in any language that quantitatively assess preferences of patients for the pharmacological management of inflammatory arthritis (rheumatoid arthritis, spondyloarthritis and juvenile idiopathic arthritis).

Strategies to Improve Health Care Provider Prescription of and Patient Adherence to Guideline-Recommended Cardiovascular Medications for Atherosclerotic Occlusive Disease: Protocol for Two Systematic Reviews and Meta-Analyses of Randomized Controlled Trials.

Background: In patients with atherosclerotic occlusive diseases, systematic reviews and meta-analyses of randomized controlled trials (RCTs) report that antiplatelets, statins, and antihypertensives reduce the risk of major adverse cardiac events, need for revascularization procedures, mortality, and health care resource use. However, evidence suggests that these patients are not prescribed these medications adequately or do not adhere to them once prescribed.

Objective: We aim to systematically review and meta-analyze RCTs examining the effectiveness of implementation or adherence-supporting strategies for improving health care provider prescription of, or patient adherence to, guideline-recommended cardiovascular medications in patients with atherosclerotic occlusive disease.

Distribution of airway pressure opening in the lungs measured with electrical impedance tomography (POET): a prospective physiological study.

Background: In patients with acute hypoxemic respiratory failure (AHRF) under mechanical ventilation, the change in pressure slope during a low-flow insufflation indicates a global airway opening pressure (AOP) needed to reopen closed airways and may be used for titration of positive end-expiratory pressure.

Objectives: To understand 1) if airways open homogeneously inside the lungs or significant regional AOP variations exist; 2) whether the pattern of the pressure slope change during low-flow insufflation can indicate the presence of regional AOP variations.

Methods: Using electrical impedance tomography, we recorded low-flow insufflation maneuvers (< 10 L/min) starting from end-expiratory positive pressure 0-5 cmHO.

The association between physician sex and patient outcomes: a systematic review and meta-analysis.

Background: Some prior studies have found that patients treated by female physicians may experience better outcomes, as well as lower healthcare costs than those treated by male physicians. Physician-patient sex concordance may also contribute to better patient outcomes. However, other studies have not identified a significant difference.

Development of water safety risk matrices to improve water safety in Arctic drinking water systems in Nunavut, Canada.

Safe drinking water is key to individual and community health. Water safety is often evaluated based on whether or not a community's drinking water meets the quality standards specified by a governing authority. These water quality standards address many microbial and chemical water safety risks but may not capture risks that are difficult to quantify or community-specific needs and preferences.

Olutasidenib in combination with azacitidine induces durable complete remissions in patients with relapsed or refractory mIDH1 acute myeloid leukemia: a multicohort open-label phase 1/2 trial.

Background: Olutasidenib is a potent, selective, oral, small molecule inhibitor of mutant IDH1 (mIDH1) which induced durable remissions in high-risk, relapsed/refractory (R/R) mIDH1 AML patients in a phase 1/2 trial. We present a pooled analysis from multiple cohorts of the phase 1/2 trial of patients with R/R AML who received combination olutasidenib and azacitidine therapy.

Methods: Adult patients with mIDH1 AML received 150 mg olutasidenib twice daily plus standard-of-care azacitidine (OLU + AZA) and were evaluated for response and safety.

What does cancer screening have to do with tomato growing?

Cancer screening is considered to be a major strategy for combatting cancer. The United States Preventive Services Task Force (USPSTF) recommends screening for five cancers, but the strength of evidence about the effectiveness of screening is limited. To gain insights into the efficacy of early detection requires prospective, blinded, placebo-controlled clinical trials with decades of follow-up and inclusion of millions of participants.

Theory of mind in trichotillomania: A cross-sectional comparison with healthy controls.

Background: Theory of mind (ToM) is the ability to make correct inferences from one's own or another person's mental states, such as thoughts, beliefs, desires, and intentions. Although there are a limited number of studies in the literature examining the social cognitive functions of patients with trichotillomania (TTM), no studies have evaluated ToM. This study aimed to compare the ToM skills of patients with TTM and healthy controls.

Frequency and Impact of Constitutional Mismatch Repair Deficiency in Patients With High-Grade Glioma, a Retrospective Analysis of 7 Years in Pakistan: an IRRDC Study.

Purpose: Constitutional mismatch repair deficiency (CMMRD) is a genetic cancer predisposition syndrome among children and young adults. This study aimed to evaluate the frequency of CMMRD among patients with pediatric high-grade glioma (pHGG) in a single tertiary care center in Pakistan, a country with high consanguinity rates.

Patients And Methods: We reviewed the data of patients age <18 years with pHGG, anaplastic astrocytoma, and diffuse midline glioma (DMG) with CMMRD testing between 2016 and 2023.

Exploring the Social Determinants of Health in Nutrition Care for South Asian Communities: A Narrative Review.

The South Asian (SA) diasporic communities in Canada experience a greater burden of diabetes and cardiovascular disease (CVD) compared to white populations. Nutrition interventions often focus on individual behaviours and fail to consider that the social determinants of health (SDH) have a greater impact on chronic disease risk. A narrative review was conducted to identify the SDH in nutrition care interventions for the SA diaspora in Canada.

Structural brain correlates of externalizing traits and symptoms in the IMAGEN sample.

The evidence supporting the presence of individual brain structure correlates of the externalizing spectrum (EXT) is sparse and mixed. To date, large-sample studies of brain-EXT relations have mainly found null to very small effects by focusing exclusively on either EXT-related personality traits (e.g.

Mapping TcdB interactions with host cell-surface and intracellular factors using proximity-dependent biotinylation labeling.

Many bacterial toxins exert their cytotoxic effects by enzymatically inactivating one or more cytosolic targets in host cells. To reach their intracellular targets, these toxins possess functional domains or subdomains that interact with and exploit various host factors and biological processes. Despite great progress in identifying many of the key host factors involved in the uptake of toxins, significant knowledge gaps remain as to how partially characterized and newly discovered microbial toxins exploit host factors or processes to intoxicate target cells.

The Accuracy of Cardiac Surface Conduction Velocity Measurements.

Background: Conduction velocity (CV) is a measure of the health of myocardial tissue. It can be measured by taking differences in local activation times from intracardiac electrodes. Several factors introduce error into the measurement, among which ignoring the 3-dimensional aspect is a major detriment.

A conceptual framework for identifying and managing system vulnerabilities for diversion of controlled substances in healthcare.

Purpose: Diversion or theft of controlled substances is a recognized problem affecting healthcare systems globally. The purpose of this study was to develop a framework for identifying and characterizing system factors leading to vulnerabilities for diversion within hospitals.

Methods: We applied a qualitative framework method, which involved 1) compiling a list of critical diversion vulnerabilities through observations and proactive risk analyses in the inpatient pharmacy, emergency department and intensive care unit of two Canadian hospitals; 2) coding the vulnerabilities into deductively and inductively derived themes and subthemes; and 3) building a conceptual framework.
