- BackgroundHIV remains a major public health issue, especially in Eastern and Southern Africa. Pre-exposure prophylaxis is highly effective when adhered to, but its effectiveness is limited by cost, user acceptability and uptake. The cost of a non-inferiority phase III trial is likely to be prohibitive, and thus, it is essential to select the best possible drug, dose and schedule in advance. The aim of this study, the Combined HIV Adolescent PrEP and Prevention Study (CHAPS), is to investigate the drug, dose and schedule of pre-exposure prophylaxis (PrEP) required for the protection against HIV and the acceptability of PrEP amongst young people in sub-Saharan Africa, and hence to inform the choice of intervention for future phase III PrEP studies and to improve strategies for PrEP implementation.MethodsWe propose a mixed-methods study amongst young people aged 13–24 years. The first component consists of qualitative research to identify the barriers and motivators towards the uptake of PrEP amongst young people in South Africa, Uganda and Zimbabwe. The second component is a randomised clinical trial (ClinicalTrials.gov NCT03986970, June 2019) using a novel ex vivo HIV challenge method to investigate the optimal PrEP treatment (FTC-TDF vs FTC-TAF), dose and schedule. We will recruit 144 amongst HIV-negative uncircumcised men aged 13–24 years from voluntary male medical circumcision clinics in two sites (South Africa and Uganda) and randomise them into one of nine arms. One group will receive no PrEP prior to surgery; the other arms will receive either FTC-TDF or FTC-TAF, over 1 or 2 days, and with the final dose given either 6 or 20 h prior to surgery. We will conduct an ex vivo HIV challenge on their resected foreskin tissue.DiscussionThis study will provide both qualitative and quantitative results to help decide the optimum drug, dose and schedule for a future phase III trial of PrEP. The study will also provide crucial information on successful strategies for providing PrEP to young people in sub-Saharan Africa.Trial registrationClinicalTrials.govNCT03986970.

- Objective The ability of occupational health and safety (OHS) legislation and regulatory enforcement to prevent workplace injuries and illnesses is contingent on political, economic, and organizational conditions. This systematic review of qualitative research articles considers how OHS legislation and regulatory enforcement are planned and implemented. Methods A comprehensive search of peer-reviewed, English-language articles published between 1990 and 2013 yielded 11 947 articles. We identified 34 qualitative articles as relevant, 18 of which passed our quality assessment and proceeded to meta-ethnographic synthesis. Results The synthesis yielded four main themes: OHS regulation formation, regulation challenges, inspector organization, and worker representation in OHS. It illuminates how OHS legislation can be based on normative suppositions about worker and employer behavior and shaped by economic and political resources of parties. It also shows how implementation of OHS legislation is affected by "general duty" law, agency coordination, resourcing of inspectorates, and ability of workers to participate in the system. Conclusions The review identifies methodological gaps and promising areas for further research in "grey" zones of legislation implementation.
