Effectiveness of a peer-led adolescent mental health intervention on HIV virological suppression and mental health in Zimbabwe: Baseline and Endline questionnaires

Vicky Simms & Silindweyinkosi Chinoda
Adolescents living with HIV have poor virological suppression and high levels of common mental disorders. In Zimbabwe the Zvandiri adolescent peer support programme is effective at improving ART adherence and virological suppression. We assessed the effect of training peer supporters in problem-solving therapy (PST) using a cluster-randomised controlled trial. Sixty clinics stratified by district were randomised 1:1 to either normal Zvandiri peer support or a peer supporter trained in PST by Friendship Bench. We enrolled...

Reuling, Lisanne A Van De Schans, Luc E Coffeng, Kjerstin Lanke, Lisette Meerstein-Kessel, Wouter Graumans, Geert-Jan Van Gemert, Karina Teelen, Rianne Siebelink-Stoter, Marga Van De Vegte-Bolmer, Quirijn De Mast, André J Van Der Ven, Karen Ivinson, Cornelus C Hermsen, Sake De Vlas, John Bradley, Katharine A Collins, Christian F Ockenhouse, James McCarthy, Robert W. Sauerwein & Teun Bousema
Background: Malaria elimination strategies require a thorough understanding of parasite transmission from human to mosquito. A clinical model to induce gametocytes to understand their dynamics and evaluate transmission-blocking interventions (TBI) is currently unavailable. Here, we explore the use of the well-established Controlled Human Malaria Infection model (CHMI) to induce gametocyte carriage with different antimalarial drug regimens. Methods: In a single centre, open-label randomised trial, healthy malaria-naive participants (aged 18–35 years) were infected with Plasmodium falciparum...

Data from: Understanding willingness to use oral pre-exposure prophylaxis for HIV prevention among men who have sex with men in China

Xia Wang, Adam Bourne, Pulin Liu, Jiangli Sun, Thomas Cai, Gitau Mburu, Matteo Cassolato, Bangyuan Wang & Wang Zhou
Background: Oral pre-exposure prophylaxis (PrEP) is recommended as an additional prevention choice for men who have sex with men (MSM) at substantial risk of HIV. The aim of this study was to evaluate the extent, and reasons, for MSM’s willingness to use oral PrEP in Wuhan and Shanghai, China. Methods: Between May and December 2015, a cross-sectional survey was conducted among 487 MSM recruited through snowball sampling in physical locations frequented by MSM and through...

MAISHA Cluster Randomised Trial - Couples Survey Data

Tanya Abramsky & Sheila Harvey
The MAISHA study (component A) is a mixed-methods evaluation, including a cluster randomised trial (CRT), of a small group based social empowerment intervention to prevent intimate partner violence (IPV) against women in Mwanza city, Tanzania. The trial was conducted among women already participating in a group-based microfinance scheme, with the microfinance group being the unit of randomisation and (in the intervention arm) the unit of intervention delivery. The CRT involved two surveys of trial participants...

Effectiveness of a peer-led adolescent mental health intervention on HIV virological suppression and mental health in Zimbabwe: data collection documents

Victoria Simms
In Zimbabwe, the Zvandiri adolescent peer-support programme is effective at improving virological suppression. We assessed the effect of training Zvandiri peer-counsellors known as Community Adolescent Treatment Supporters (CATS) in problem-solving therapy (PST) on virological suppression and mental health outcomes. Sixty clinics were randomised 1:1 to either normal Zvandiri peer-counselling or a peer-counsellor trained in problem solving therapy. We enrolled on average 14 adolescents per clinic (N=842) aged 10-19 years, living with HIV who screened positive...

Data from: Temperature and population density determine reservoir regions of spatial persistence in highland malaria

Amir S. Siraj, Menno J. Bouma, Mauricio Santos-Vega, Asnakew K. Yeshiwondim, Dale S. Rothman, Damtew Yadeta, Paul C. Sutton & Mercedes Pascual
A better understanding of malaria persistence in highly seasonal environments such as highlands and desert fringes requires identifying the factors behind the spatial reservoir of the pathogen in the low season. In these ‘unstable’ malaria regions, such reservoirs play a critical role by allowing persistence during the low transmission season and therefore, between seasonal outbreaks. In the highlands of East Africa, the most populated epidemic regions in Africa, temperature is expected to be intimately connected...

Data from: Substantial contribution of submicroscopical Plasmodium falciparum gametocyte carriage to the infectious reservoir in an area of seasonal transmission.

André Lin Ouédraogo, Teun Bousema, Petra Schneider, Sake J. De Vlas, Edith Ilboudo-Sanogo, Nadine Cuzin-Ouattara, Issa Nébié, Will Roeffen, Jan Peter Verhave, Adrian J.F. Luty & Robert Sauerwein
Background: Man to mosquito transmission of malaria depends on the presence of the sexual stage parasites, gametocytes, that often circulate at low densities. Gametocyte densities below the microscopical threshold of detection may be sufficient to infect mosquitoes but the importance of submicroscopical gametocyte carriage in different transmission settings is unknown. Methodology/Principal Findings: Membrane feeding experiments were carried out on 80 children below 14 years of age at the end of the wet season in an...

Data from: Population need for primary eye care in Rwanda: a national survey

Tess Bright, Hannah Kuper, David Macleod, David Musendo, Peter Irunga & Jennifer L.Y. Yip
Background: Universal access to Primary Eye Care (PEC) is a key global initiative to reduce and prevent avoidable causes of visual impairment (VI). PEC can address minor eye conditions, simple forms of uncorrected refractive error (URE) and create a referral pathway for specialist eye care, thus offering a potential solution to a lack of eye health specialists in low-income countries. However, there is little information on the population need for PEC, including prevalence of URE...
