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...

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...

Quality of care in a differentiated HIV service delivery intervention in Tanzania: A mixed methods study

Nwanneka Okere, Judith Meta, Werner Maokola, Giulia Martelli, Eric Van Praag, Denise Naniche, Gabriela Gomez, Anton Pozniak, Tobias Rinke De Wit, Josien De Klerk & Sabine Hermans
Background: Differentiated service delivery (DSD) offers benefits to people living with HIV (improved access, peer support), and the health system (clinic decongestion, efficient service delivery). ART clubs, 15-30 clients who usually meet within the community, are one of the most common DSD options. However, evidence about the quality of care (QoC) delivered in DSD is still limited. Materials and Methods: We conducted a concurrent triangulation mixed methods study as part of the Test & Treat...

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...

Data from: Weekend admission as an independent predictor of mortality: an analysis of Scottish hospital admissions

Adam E. Handel, Sunil V. Patel, Andrew Skingsley, Katrina Bramley, Roma Sobieski & Sreeram V. Ramagopalan
OBJECTIVES: Weekend admissions have been shown to be associated with an increased risk of mortality compared with weekday admissions for many diagnoses. We analysed emergency department admissions within the Scottish National Health Service to investigate whether mortality is increased in case of weekend emergency department admissions. DESIGN: A cohort study. SETTING: Scotland National Health Service (NHS) emergency departments. PARTICIPANTS: 5 271 327 emergency department admissions between 1999 and 2009. We included all patients admitted via...

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...

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: Clarifying life lost due to cold and heat: a new approach using annual time series.

Design: Time series regression analysis of annual deaths in relation to annual summaries of cold and heat. Setting: London, UK. Participants: 3 530 280 deaths from all natural causes among London residents between October 1949 and September 2006. Main outcome measures: Change in annual risk of death (all...

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...

Data from: Safety and immunogenicity of H1/IC31®, an adjuvanted TB subunit vaccine, in HIV-infected adults with CD4+ Lymphocyte counts greater than 350 cells/mm3: a phase II, multi-centre, double-blind, randomized, placebo-controlled trial

Kagina, Elisabeth J. Hughes, Thomas J. Scriba, Willem A. Hanekom, Søren T. Hoff, Peter Bang, Ingrid Kromann, Claudia Daubenberger, Peter Andersen & Gavin J. Churchyard
Background: Novel tuberculosis vaccines should be safe, immunogenic, and effective in various population groups, including HIV-infected individuals. In this phase II multi-centre, double-blind, placebo-controlled trial, the safety and immunogenicity of the novel H1/IC31 vaccine, a fusion protein of Ag85B-ESAT-6 (H1) formulated with the adjuvant IC31, was evaluated in HIV-infected adults. Methods: HIV-infected adults with CD4+ T cell counts >350/mm3 and without evidence of active tuberculosis were enrolled and followed until day 182. H1/IC31 vaccine or...

Background: Selection for resistance to azithromycin (AZM) and other antibiotics such as tetracyclines and lincosamides remains a concern with long-term AZM use for treatment of chronic lung diseases (CLD). We investigated the impact of 48 weeks of AZM on the carriage and antibiotic resistance of common respiratory bacteria among children with HIV-associated CLD. Methods: Nasopharyngeal (NP) swabs and sputa were collected at baseline, 48 and 72 weeks from participants with HIV-associated CLD randomised to receive...

De Jong, Amanda Fabra-García, John Bradley, Will Roeffen, Edwin Lasonder, Giuliana Gremo, Evelin Schwarzer … & Matthijs M. Jore
Infection with Plasmodium can elicit antibodies that inhibit parasite survival in the mosquito, when they are ingested in an infectious blood meal. Here, we determine the transmission-reducing activity (TRA) of naturally acquired antibodies from 648 malaria-exposed individuals using lab-based mosquito-feeding assays. Transmission inhibition is significantly associated with antibody responses to Pfs48/45, Pfs230, and to 43 novel gametocyte proteins assessed by protein microarray. In field-based mosquito-feeding assays the likelihood and rate of mosquito infection are significantly...
