We aimed to assess neurodegenerative changes in the rhinencephalon via magnetic resonance imaging (MRI) and relate it to olfactory function and diabetic peripheral neuropathy (DPN) in adults with type 1 diabetes (T1D). Individuals aged 18-65 with T1D duration over 10 years and control healthy subjects underwent olfactory assessment using Sniffin'Sticks and brain MRI to assess volumetric measurements of the olfactory bulbs and piriform cortex thickness. 32 T1D (24 males) aged 43.

Background: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) is key for policy making. Low back pain is the leading cause of disability in terms of years lived with disability (YLDs). Due to sparse data, a current limitation of GDB is that a uniform severity distribution is presumed based on 12-Item Short Form Health Survey scores derived from US Medical Expenditure Panel Surveys (MEPS).

Background: Vascular anomalies often result in aesthetic flaws, pain, and impair the quality of life. They require challenging treatments that frequently do not provide the desired results. The mammalian target of rapamycin (mTOR) is directly involved in the development of these malformations.

Article Synopsis
  • - The study aimed to analyze how exposure to immunosuppressive and immunomodulatory agents (IIAs) affects severe outcomes of COVID-19, using a large cohort from British Columbia, Canada, with participants aged 18 and older who tested positive for the virus.
  • - It examined various types of IIAs, including traditional disease-modifying drugs, immunosuppressants, TNF inhibitor biologics, and glucocorticoids, looking for their impact on COVID-19 hospitalizations, ICU admissions, and deaths within 60 days of diagnosis.
  • - Findings indicated that certain IIAs, notably mycophenolate mofetil (MMF), showed a significantly higher risk for COVID-19 hospitalizations and severe

It has been estimated that in the next decade, IHD prevalence, DALYs and deaths will increase more significantly in EMR than in any other region of the world. This study aims to provide a comprehensive description of the trends in the burden of ischemic heart disease (IHD) across the countries of the Eastern Mediterranean Region (EMR) from 1990 to 2019. Data on IHD prevalence, disability-adjusted life years (DALYs), mortality, DALYs attributable to risk factors, healthcare access and quality index (HAQ), and universal health coverage (UHC) were extracted from the Global Burden of Disease (GBD) database for EMR countries.

Purpose: This article describes the development of the Vancouver airways health literacy tool (VAHLT), a novel measure of skill-based health literacy specific to chronic airway diseases (CADs). Across several phases, psychometric characteristics of the VAHLT were examined and used to guide its development.

Methods: An initial pool of 46 items was developed using input from patients, clinicians, researchers, and policy-makers.

Background: Hypertensive heart disease (HHD), one of the end-organ damage consequences of hypertension, is an important public health issue worldwide. Data on the HHD burden in the Eastern Mediterranean region (EMR) are scarce. We aimed to investigate the burden of HHD in the EMR, its member countries, and globally from 1990 to 2019.

Purpose: Mental health and well-being trajectories are not expected to be homogeneous in diverse clinical populations. This exploratory study aims to identify subgroups of patients with cancer receiving radiation therapy who have different mental health and well-being trajectories, and examine which socio-demographic, physical symptoms, and clinical variables are associated with such trajectories.

Methods: Retrospective analysis of radiation therapy patients diagnosed with cancer in 2017 was conducted using data from the Ontario Cancer Registry (Canada) and linked with administrative health data.

Objectives: To determine the impact of the introduction of biologic DMARDs (bDMARDs) on severe infections among people newly diagnosed with RA compared with non-RA individuals.

Methods: In this population-based retrospective cohort study using administrative data (from 1990-2015) for British Columbia, Canada, all incident RA patients diagnosed between 1995 and 2007 were identified. General population controls with no inflammatory arthritis were matched to RA patients based on age and gender, and were assigned the diagnosis date (i.

Article Synopsis
  • The lifespan of people living with HIV (PLWH) has significantly improved due to modern antiretroviral therapy, leading to increased concerns about chronic comorbidities among this population.
  • A study in British Columbia compared disability-adjusted life years (DALYs) related to chronic conditions between PLWH and HIV-negative individuals from 2001-2012, revealing that PLWH experienced double the DALYs associated with chronic comorbidities.
  • Non-AIDS-defining cancers and cardiovascular diseases were the primary contributors to DALYs in both groups, highlighting a concerning disparity in health between PLWH and their HIV-negative counterparts due to factors like health behaviors and treatment effects.

Background: The burden of heart failure (HF) is high globally, but information on its burden in the Eastern Mediterranean Region (EMR) is limited. This study provides a systematic analysis of the burden and underlying causes of HF in the EMR, including at the country level, between 1990 and 2019.

Methods: We used the 2019 Global Burden of Disease (GBD) data for estimates of prevalence, years lived with disability (YLDs), and underlying causes of HF in the EMR.

Article Synopsis
  • HIV/AIDS remains a significant public health issue in sub-Saharan Africa, with current efforts falling short of global targets for eradication set by UNAIDS and the SDGs.
  • The study utilized extensive data from various HIV prevalence surveys to estimate localized HIV infection rates across 43 African countries, focusing on specific age and sex groups from 2000 to 2018.
  • Findings revealed wide disparities in HIV prevalence within countries and districts, indicating that age and sex stratification provides more nuanced insights into the epidemic, which can help tailor prevention and treatment efforts more effectively.

The aims of this study were (1) to develop a comprehensive risk-of-death and life expectancy (LE) model and (2) to provide data on the effects of multiple risk factors on LE. We used data for Canada from the Global Burden of Disease (GBD) Study. To create period life tables for males and females, we obtained age/sex-specific deaths rates for 270 diseases, population distributions for 51 risk factors, and relative risk functions for all disease-exposure pairs.

Cystathionine beta-synthase (CBS) is a pivotal enzyme of the transsulfuration pathway responsible for diverting homocysteine to the biosynthesis of cysteine and production of hydrogen sulfide (HS). Aberrant upregulation of CBS and overproduction of HS contribute to pathophysiology of several diseases including cancer and Down syndrome. Therefore, pharmacological CBS inhibition has emerged as a prospective therapeutic approach.

Purpose: Disease prevalence estimates from population-based administrative databases are often biased due to measurement (misclassification) errors. The purpose of this article is to review the methodology for estimating disease prevalence in administrative data, with a focus on bias correction.

Source: Several approaches to bias correction in administrative data were reviewed and application of these methods was demonstrated using an example from the literature: physician claims and hospitalization data were employed to estimate diabetes prevalence in Ontario, Canada.
