Predictive equation derived from 6,497 doubly labelled water measurements enables the detection of erroneous self-reported energy intake.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

Comparison between ruptured anterior choroidal artery aneurysms and ruptured intracranial aneurysms in other locations in relation to aneurysm dimensions at rupture.

Purpose: It was noticed that anterior choroidal artery (AChoA) aneurysms appear to rupture at relatively smaller sizes compared with aneurysms in other intracranial locations, based on anecdotal clinical experience. We therefore aimed to compare ruptured AChoA aneurysms with other ruptured aneurysms in other intracranial locations, pertaining to aneurysm dimensions. This may help in finding out if the rupture risk stratification, based on the amalgamation of aneurysms of multiple locations in one group, precisely estimates aneurysm rupture risk.

Negative Staining Electron Microscopy of a Highly Flexible Sec1/Munc18 Protein Complex Stabilized by Glutaraldehyde Crosslinking.

Negative staining electron microscopy is one of the easiest ways to determine the shape and dimensions of multimeric protein complexes over 100 kDa molecular weight. This method requires small volumes (< 10 μL) of dilute protein (0.01-0.

Development and Implementation of a Structured and Innovative Faculty-Wide Mentorship Program for a Large Department of Psychiatry.

Objectives: Mentorship supports faculty to succeed in their careers with confidence, resilience, and satisfaction. To address inequities evident with an informal approach, a formal mentorship program was designed and implemented.

Methods: The Quality Implementation Framework (QIF) was applied.

Glycogen synthase GYS1 overactivation contributes to glycogen insolubility and malto-oligoglucan-associated neurodegenerative disease.

Polyglucosans are glycogen molecules with overlong chains, which are hyperphosphorylated in the neurodegenerative Lafora disease (LD). Brain polyglucosan bodies (PBs) cause fatal neurodegenerative diseases including Lafora disease and adult polyglucosan body disease (ABPD), for which treatments, biomarkers, and good understanding of their pathogenesis are currently missing. Mutations in the genes for the phosphatase laforin or the E3 ubiquitin ligase malin can cause LD.

Implementation and evaluation of a novel community-based urban mobile health clinic in Toronto, Ontario.

Setting: Despite Canada's single-payer health system, marginalized populations often experience poor health outcomes and barriers to healthcare access. In response, mobile health clinics (MHCs) have been deployed in several cities across Canada. MHCs are well established in the United States; however, little is known about their role and impact in a country with universal healthcare.

The birth of the virtual clinic: welcome to the Mediverse.

The COVID-19 pandemic triggered a global pivot to virtual care (VC) technologies. While there has been considerable academic work exploring the "how" of VC, few studies have explored the impact of this pivot, its unintended consequences, and its governing rationales. This study addresses this gap in relation to care, professional identity and the evolving requirements for health professions education.

Pre-T cell receptor-α immunodeficiency detected exclusively using whole genome sequencing.

Maturation of αβ lineage T cells in the thymus relies on the formation and cell surface expression of a pre-T cell receptor (TCR) complex, composed of TCRβ chain and pre-TCRα (pTCRα) chain heterodimers, giving rise to a diverse T cell repertoire. Genetic aberrations in key molecules involved in T cell development lead to profound T cell immunodeficiency. Definitive genetic diagnosis guides treatment choices and counseling.

Validity of the Diabetic Wound Assessment Learning Tool.

Purpose: The development of the Diabetic Wound Assessment Learning Tool (DiWALT) has previously been described. However, an examination of its application to a larger, more heterogeneous group of participants is lacking. In order to allow for a more robust assessment of the psychometric properties of the DiWALT, we applied it to a broader group of participants.

Mepolizumab real-world effectiveness in severe asthma with an eosinophilic phenotype and overlapping severe allergic asthma.

Background: Some patients with severe asthma have overlapping allergic and eosinophilic phenotypes and may be eligible for anti-eosinophilic or anti-IgE biologics.

Objective: This post hoc sub-analysis assessed real-world mepolizumab effectiveness in patients with overlapping allergic and eosinophilic phenotypes, using 1-year data from the international, prospective REALITI-A study.

Methods: The clinically significant asthma exacerbation (CSE) rate was assessed 1 year prior to (pre-treatment) and following (follow-up) mepolizumab treatment, stratified by baseline total IgE levels (tIgE; <60, 60-<190, 190-<550, and ≥550 kU/L), atopic status (yes/no/unknown), prior omalizumab use (yes/no), geographic baseline omalizumab eligibility (eligible/non-eligible), and baseline tIgE level and blood eosinophil count (BEC) threshold combinations (<81 or ≥81 kU/L and <300 or ≥300 cells/µL).

Gender identity and activity limitations: A national study on transgender and non-binary Canadians.

Introduction: Activity limitations among transgender and non-binary individuals remain largely unexplored using population-based samples. This study examines the risk of activity limitations across different gender identities in Canada.

Method: Using data from the 2021 Canadian long-form Census, logistic regressions estimated the adjusted odds of reporting activity limitations (seeing, hearing, mobility/dexterity, mental, cognitive, and other) across gender identities.

Chimeric Antigen Receptor-T Cells in Colorectal Cancer: Pioneering New Avenues in Solid Tumor Immunotherapy.

Colorectal cancer (CRC) remains a major global health burden, being one of the most prevalent cancers with high mortality rates. Despite advances in conventional treatment modalities, patients with metastatic CRC often face limited options and poor outcomes. Chimeric antigen receptor-T (CAR-T) cell therapy, initially successful in hematologic malignancies, presents a promising avenue for treating solid tumors, including CRC.

Comparison of a non-invasive point-of-care measurement of anemia to conventionally used HemoCue devices in Gambella refugee camp, Ethiopia, 2022.

Annual surveys of refugees in Gambella, Ethiopia suggest that anemia is a persistent public health problem among non-pregnant women of reproductive age (NP-WRA, 15-49 years). Measurement of anemia in most refugee camp settings is conducted using an invasive HemoCue 301. We assessed the accuracy and precision of a non-invasive, pulse CO-oximeter in measuring anemia among NP-WRA in four Gambella refugee camps.

Pharmacophore modeling and QSAR analysis of anti-HBV flavonols.

Due to its global burden, Targeting Hepatitis B virus (HBV) infection in humans is crucial. Herbal medicine has long been significant, with flavonoids demonstrating promising results. Hence, the present study aimed to establish a way of identifying flavonoids with anti-HBV activities.
