Introduction: GRADE and other Evidence to Decision (EtD) frameworks are widely used by guideline development groups (GDG) and other decision-makers. When GDGs judge the magnitude of desirable and undesirable health outcomes on EtDs, they typically categorize them as trivial, small, moderate or large. However, generic judgment or decision thresholds (DTs) that could guide the user about such estimates of effect size or serve as references for interpretation of findings are not yet available.

Background: As researchers and practitioners in the field of global health continue to acknowledge the ongoing impact of colonialism in their work, the call for decolonized research has increased. This has particular relevance in the field of sexual and reproductive health. Despite this recognized need, there is no singularly agreed upon definition of what it means to conduct decolonized research using decolonized methodologies.

We found that rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing and reverse transcriptase (RT)-PCR-confirmed infection were approximately 50% higher in a population-based cohort of people with HIV compared with a matched cohort of people without HIV during the Omicron era (2 January 2022 to 31 March 2023) in Ontario, Canada, after controlling for age, sex, residential census tract, and country of birth. Rates of coronavirus disease 2019 (COVID-19)-related hospitalization and/or death were more than double. Differences persisted independent of vaccination, healthcare access, and COVID-19 diagnosis.

Article Synopsis
  • Enteral nutrition (EN) is the preferred method for providing nutritional support to critically ill patients, but it's uncertain whether continuous or intermittent feeding is better for minimizing gastrointestinal complications like diarrhea and achieving nutritional goals.
  • This systematic review aims to analyze existing studies to compare the effects of continuous vs. intermittent EN on gastrointestinal issues and nutritional outcomes in critically ill patients.
  • The research will follow the PRISMA-P guidelines, assessing various adverse effects, ICU stay duration, and mortality, and will share findings through peer-reviewed journals and conferences, without needing ethical approval since no new data will be collected.

Introduction: The Road to Recovery (R2R) Initiative is an innovative model of substance use care that seeks to increase treatment capacity by creating approximately 100 new addiction treatment beds to provide on-demand addiction care in Vancouver, British Columbia, for patients with substance use disorders. The new model also coordinates the region's existing clinical substance use services to support patients across a care continuum that includes traditional office-based addiction treatment and harm reduction services, early withdrawal management and more intensive abstinence-based treatment programming. To understand the impact of offering on-demand and coordinated substance use care, an observational cohort of individuals who access any R2R clinical service will be created to examine health and social outcomes over time.

Objective: Cluster randomised trials (CRTs) are used for evaluating health-related interventions in low-income and middle-income countries (LMICs) but raise complex ethical issues. To inform the development of future ethics guidance, we aim to characterise CRTs conducted exclusively in LMICs by examining the types of clusters, settings, author affiliations and primary clinical focus and to evaluate adherence to trial registration and ethics reporting requirements over time.

Design: A systematic scoping review using the Preferred Reporting Items for Systematic Review and Meta-Analyses Extension for Scoping Reviews.

Background Stigma towards sexually active young people presents profound barriers to uptake of sexual and reproductive health (SRH) services, including HIV testing and contraception. Yet, few studies have examined adolescent SRH stigma trajectories over time. To address this knowledge gap, we examined associations between social-ecological factors and trajectories of adolescent SRH stigma among urban refugee youth in Kampala, Uganda.

Introduction: The commonly used frequentist paradigm of null hypothesis statistics testing with its reliance on the p-value and the corresponding notion of 'statistical significance' has been under ongoing criticism. Misinterpretation and misuse of the p-value have contributed to publication bias, unreliable studies, frequent false positives, fraud and mistrust in results of scientific studies. While p-values themselves are still useful, part of the problem may be the confusion between statistical and clinical significance.

Background: High-income countries offer social assistance (welfare) programs to help alleviate poverty for people with little or no income. These programs have become increasingly conditional and stringent in recent decades based on the premise that transitioning people from government support to paid work will improve their circumstances. However, many people end up with low-paying and precarious jobs that may cause more poverty because they lose benefits such as housing subsidies and health and dental insurance, while incurring job-related expenses.

People’s values are an important driver in healthcare decision making. The certainty of an intervention’s effect on benefits and harms relies on two factors: the certainty in the measured effect on an outcome in terms of risk difference and the certainty in its value, also known as utility or importance. The GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) working group has proposed a set of questions to assess the risk of bias in a body of evidence from studies investigating how people value outcomes.
