Caregiver-assisted testing with HIV self-test kits for children 18 months and older
Caregiver-assisted testing using HIV self-test (CG-HIVST) kits has been proposed to enhance paediatric HIV case finding and contribute toward ending paediatric HIV/AIDS by 2030. We conducted a systematic review to assess the risks and benefits of CG-HIVST. We searched nine electronic databases and consulted experts to identify relevant articles through 5 February, 2022. Studies comparing CG-HIVST to other testing services among children over 18-m…
Use of indirect evidence from HIV self-testing to inform the WHO hepatitis C self-testing recommendation
Sars-CoV-2 transmission in schools
Factors associated with current substance use among a sample of homeless individuals in Cape Town, South Africa
Homelessness is a global issue that is often associated with substance use. Research on this relationship in low- to middle-income countries (LMIC) is limited. We aimed to explore which factors are associated with substance use through secondary data analysis of a sample of 472 adults who attended services for homeless individuals in Cape Town, South Africa. Logistic regression was utilized to investigate if length of homelessness was associated …
Prioritising gender, equity, and human rights in a GRADE-based framework to inform future research on self care for sexual and reproductive health and rights
Introduction: In January 2019, the WHO reviewed evidence to develop global recommendations on self-care interventions for sexual and reproductive health and rights (SRHR). Identification of research gaps is part of the WHO guidelines development process, but reliable methods to do so are currently lacking with gender, equity and human rights (GER) infrequently prioritised. Methods: We expanded a prior framework based on Grading of Evidence, Asses…
What is the evidence for transmission of Covid-19 by children in schools? A living systematic review
Examining the effects of HIV self‐testing compared to standard HIV testing services
Introduction : HIV self‐testing (HIVST) is a discreet and convenient way to reach people with HIV who do not know their status, including many who may not otherwise test. To inform World Health Organization (WHO) guidance, we assessed the effect of HIVST on uptake and frequency of testing, as well as identification of HIV‐positive persons, linkage to care, social harm, and risk behaviour. Methods : We systematically searched for studies comparing…
Using GRADE as a framework to guide research on the sexual and reproductive health and rights (SRHR) of women living with HIV – methodological opportunities and challenges
In March 2016, WHO reviewed evidence to develop global recommendations on the sexual and reproductive health and rights (SRHR) of women living with HIV. Systematic reviews and a global survey of women living with HIV informed the guideline development decision-making process. New recommendations covered abortion, Caesarean section, safe disclosure, and empowerment and self-efficacy interventions. Identification of key research gaps is part of the…
