Randomized Controlled TrialProtective efficacy of prolonged co-trimoxazole prophylaxis in HIV-exposed children up to age 4 years for the prevention of malaria in Uganda: a randomised controlled open-label trial.
WHO recommends daily co-trimoxazole for children born to HIV-infected mothers from 6 weeks of age until breastfeeding cessation and exclusion of HIV infection. We have previously reported on the effectiveness of continuation of co-trimoxazole prophylaxis up to age 2 years in these children. We assessed the protective efficacy and safety of prolonging co-trimoxazole prophylaxis until age 4 years in HIV-exposed children. ⋯ 203 HIV-exposed infants were enrolled between Aug 10, 2007, and March 28, 2008. After breastfeeding ended, 185 children were not infected with HIV and were randomly assigned to stop (n=87) or continue (n=98) co-trimoxazole up to age 2 years. At age 2 years, 91 HIV-exposed children who had remained on co-trimoxazole prophylaxis were randomly assigned to discontinue (n=46) or continue (n=45) co-trimoxazole from age 2 years to age 4 years. We recorded 243 malaria episodes (2·91 per person-years) in the 45 HIV-exposed children assigned to continue co-trimoxazole until age 4 years compared with 503 episodes (5·60 per person-years) in the 46 children assigned to stop co-trimoxazole at age 2 years (incidence rate ratio 0·53, 95% CI 0·39-0·71; p< 0·0001). There was no evidence of malaria incidence rebound in the year after discontinuation of co-trimoxazole in the HIV-exposed children who stopped co-trimoxazole at age 2 years, but incidence increased significantly in HIV-exposed children who stopped co-trimoxazole at age 4 years (odds ratio 1·78, 95% CI 1·19-2·66; p= 0·005). Incidence of grade 3 or 4 serious adverse events, hospital admissions, or deaths did not significantly differ between HIV-exposed, HIV-unexposed, and HIV-infected children.

Annual rates of decline in child, maternal, HIV, and tuberculosis mortality across 109 countries of low and middle income from 1990 to 2013: an assessment of the feasibility of post-2015 goals.
Measuring a country's health performance has focused mostly on estimating levels of mortality. An alternative is to measure rates of decline in mortality, which are more sensitive to changes in health policy than are mortality levels. Historical rates of decline in mortality can also help test the feasibility of future health goals (eg, post-2015). We aimed to assess the annual rates of decline in under-5, maternal, tuberculosis, and HIV mortality over the past two decades for 109 low-income and middle-income countries. ⋯ From 2005 to 2013, the mean annual rate of decline in under-5 mortality was 4·3% (95% uncertainty interval [UI] 3·9-4·6), for maternal mortality it was 3·3% (2·5-4·1), for tuberculosis mortality 4·1% (2·8-5·4), and for HIV mortality 2·2% (0·1-4·3); aspirational best-performer rates per year were 7·1% (6·8-7·5), 6·3% (5·5-7·1), 12·8% (11·5-14·1), and 15·3% (13·2-17·4), respectively. The top two country performers were Macedonia and South Africa for under-5 mortality, Belarus and Bulgaria for maternal mortality, Uzbekistan and Macedonia for tuberculosis mortality, and Namibia and Rwanda for HIV mortality. At aspirational rates of decline, The Lancet's Commission on Investing in Health target for under-5 mortality would be achieved by 50-64% of countries, 35-41% of countries would achieve the 2030 target for maternal mortality, 74-90% of countries would meet the goal for tuberculosis mortality, and 66-82% of countries would achieve the target for HIV mortality.

Randomized Controlled TrialEffectiveness of a rural sanitation programme on diarrhoea, soil-transmitted helminth infection, and child malnutrition in Odisha, India: a cluster-randomised trial.
A third of the 2·5 billion people worldwide without access to improved sanitation live in India, as do two-thirds of the 1·1 billion practising open defecation and a quarter of the 1·5 million who die annually from diarrhoeal diseases. We aimed to assess the effectiveness of a rural sanitation intervention, within the context of the Government of India's Total Sanitation Campaign, to prevent diarrhoea, soil-transmitted helminth infection, and child malnutrition. ⋯ Bill & Melinda Gates Foundation, International Initiative for Impact Evaluation (3ie), and Department for International Development-backed SHARE Research Consortium at the London School of Hygiene & Tropical Medicine.
