These thresholds may be derived from the literature, observational data, or clinical experience. The aim of this study was to determine empirical estimates for feasibility outcomes to inform future HIV pilot randomized trials.

A step towards reinvigorating the COVID-19 response: an intra-action review of the WHO Regional Office for Africa Incident Management Support Team.

The WHO Regional Office for Africa (AFRO) COVID-19 Incident Management Support Team (IMST) was first established on 21 January 2020 to coordinate the response to the pandemic in line with the Emergency Response Framework and has undergone three modifications based on intra-action reviews (IAR). An IAR of the WHO AFRO COVID-19 IMST was conducted to document best practices, challenges, lessons learnt and areas for improvement from the start of 2021 to the end of the third wave in November 2021. In addition, it was designed to contribute to improving the response to COVID-19 in the Region.

Development and validation of an international preoperative risk assessment model for postoperative delirium.

Background: Postoperative delirium (POD) is a frequent complication in older adults, characterised by disturbances in attention, awareness and cognition, and associated with prolonged hospitalisation, poor functional recovery, cognitive decline, long-term dementia and increased mortality. Early identification of patients at risk of POD can considerably aid prevention.

Methods: We have developed a preoperative POD risk prediction algorithm using data from eight studies identified during a systematic review and providing individual-level data.

Describing Engagement in the HIV Care Cascade: A Methodological Study.

Introduction: Engagement in the HIV care cascade is required for people living with HIV (PLWH) to achieve an undetectable viral load. However, varying definitions of engagement exist, contributing to heterogeneity in research regarding how many individuals are actively participating and benefitting from care. A standardized definition is needed to enhance comparability and pooling of data from engagement studies.

Key issues for stakeholder engagement in the development of health and healthcare guidelines.

Established in 2015, the Multi-Stakeholder Engagement (MuSE) Consortium is an international network of over 120 individuals interested in stakeholder engagement in research and guidelines. The MuSE group is developing guidance for stakeholder engagement in the development of health and healthcare guideline development. The development of this guidance has included multiple meetings with stakeholders, including patients, payers/purchasers of health services, peer review editors, policymakers, program managers, providers, principal investigators, product makers, the public, and purchasers of health services and has identified a number of key issues.

Measures of Retention in HIV Care: A Study Within a Review.

People living with HIV (PLHIV) need lifelong medical care. However, retention in HIV care is not measured uniformly, making it challenging to compare or pool data. The objective of this study within a review (SWAR) is to describe the assortment of definitions used for retention in HIV care in randomized controlled trials (RCTs).

Obesity and weight change during the COVID-19 pandemic in children and adults: A systematic review and meta-analysis.

Many obesity risk factors have increased during the COVID-19 pandemic, including physical inactivity, poor diet, stress, and poverty. The aim of this systematic review was to evaluate the impact of the COVID-19 pandemic, as well as associated lockdowns or restrictions, on weight change in children and adults. We searched five databases from January 2020 to November 2021.

Knowledge mobilization activities to support decision-making by youth, parents, and adults using a systematic and living map of evidence and recommendations on COVID-19: protocol for three randomized controlled trials and qualitative user-experience studies.

Introduction: The COVID-19 pandemic underlined that guidelines and recommendations must be made more accessible and more understandable to the general public to improve health outcomes. The objective of this study is to evaluate, quantify, and compare the public's understanding, usability, satisfaction, intention to implement, and preference for different ways of presenting COVID-19 health recommendations derived from the COVID-19 Living Map of Recommendations and Gateway to Contextualization (RecMap).

Methods And Analysis: This is a protocol for a multi-method study.

Risk factors for colonization and infection with multidrug-resistant Pseudomonas aeruginosa in intensive care unit: protocol for a systematic review and meta-analysis.

Background: Infection with resistant Pseudomonas aeruginosa (RPA) in the intensive care unit (ICU) is known to be either endogenous or exogenous or both, but the roles of each of these contamination routes are yet to be clarified. Data regarding prevalence, risk factors, and environmental factors associated with RPA in ICU are very scanty and even when they exist, they seem to be contradictory. So, there is a strong interest in understanding both individual and environmental factors associated with RPA infection.

Mobile Health-Supported Virtual Reality and Group Problem Management Plus: Protocol for a Cluster Randomized Trial Among Urban Refugee and Displaced Youth in Kampala, Uganda (Tushirikiane4MH, Supporting Each Other for Mental Health).

Background: Although mental health challenges disproportionately affect people in humanitarian contexts, most refugee youth do not receive the mental health support needed. Uganda is the largest refugee-hosting nation in Africa, hosting over 1.58 million refugees in 2022, with more than 111,000 living in the city of Kampala.

Design: Test-negative design.

Black Canadians' Exposure to Everyday Racism: Implications for Health System Access and Health Promotion among Urban Black Communities.

This study explores the social determinants of Black Canadians' exposure to everyday racism, its relationship to health system access, and implications for health promotion. We used data from the A/C Study survey on HIV transmission and prevention among Black Canadians. We implemented the survey (N = 1360) in 2018-2019 in Toronto and Ottawa-two large cities that together account for 42% of Canada's Black population-among self-identified Black residents aged 15-64 years, who were born in sub-Sahara Africa or the Caribbean or had a parent who was born in those regions.

Effects of inulin-type fructans supplementation on cardiovascular disease risk factors: a protocol for a systematic review and meta-analysis of controlled trials.

Introduction: This review aims to assess the effects of dietary supplementation with inulin-type fructans (ITF) compared with no supplementation on cardiovascular disease risk factors in adults and assess the quality of trial reporting using the Consolidated Standards of Reporting Trials (CONSORT) and CONSORT for abstract (CONSORT-A) checklists.

Methods And Analysis: We will search randomised controlled trials (RCTs) in MEDLINE, EMBASE, CINAHL, Emcare, AMED and the Cochrane Database of Systematic Reviews from inception to 31 March 2022, without any language restrictions. The RCTs need to administer ITF in adults for at least 2 weeks and assess effects on at least one cardiovascular risk factor.

High-Dose Thiamine Supplementation in Older Patients With Heart Failure: A Pilot Randomized Controlled Crossover Trial (THIAMINE-HF).

Background: Thiamine supplementation may improve cardiac function in older adults with heart failure (HF). Our objectives were to determine the following: (i) the feasibility of conducting a large trial of thiamine supplementation in HF; and (ii) the effects of thiamine on clinical outcomes.

Association of chiropractic integration in an Ontario community health centre with prescription opioid use for chronic non-cancer pain: a mixed methods study protocol.

Introduction: Emerging evidence from a number of primary care centres suggests that integration of chiropractic services into chronic pain management is associated with improved clinical outcomes and high patient satisfaction as well as with reductions in physician visits, specialist referrals use of advanced imaging and prescribing of analgesics. However, formal assessments of the integration of chiropractic services into primary care settings are sparse, and the impact of such integration on prescription opioid use in chronic pain management remains uncertain. To help address this knowledge gap, we will conduct a mixed methods health service evaluation of an integrated chiropractic back pain programme in an urban community health centre in Ontario, Canada.

Meta-analysis of Pragmatic and Explanatory Trials.

Pooling studies with different clinical and methodological features may lead to statistical heterogeneity, particularly if heterogeneity remains unexplained. One potential source of heterogeneity may be how much the included trials tend toward a pragmatic or explanatory design. Many tools have been developed to aid researchers in quantifying pragmatism in clinical trials, at both the design and appraisal stages.

Comparing and combining evidence of treatment effects in randomized and nonrandomized studies on the use of misoprostol to prevent postpartum hemorrhage.

Objective: Postpartum hemorrhage (PPH) is a preventable condition and the main cause of maternal death worldwide. Evidence on the effectiveness of misoprostol in the prevention of PPH has been generated from both randomized controlled trials (RCTs) and nonrandomized studies (NRS). This study aimed to compare the results of RCTs and NRS, and to compare Classical and Bayesian approaches of combining the results of RCTs and NRS on the use of misoprostol versus placebo in the prevention of PPH.

Guidelines are needed for studies of pre-treatment HIV drug resistance: a methodological study.

Background: The expansion of access to antiretroviral therapy (ART) has been accompanied by an increase in pre-treatment drug resistance (PDR). While it is critical to monitor the increasing prevalence of PDR across countries and populations to inform optimal regimen selection, the completeness of reporting is often suboptimal, limiting the interpretation and generalizability of the results. Indeed, there is no formal guidance on how studies investigating the prevalence of drug resistance should be reported.
