Background: Postpartum depression (PPD) affects approximately 17% of the women worldwide with nearly half of all cases going undetected. More research on maternal mental health, particularly among healthcare professionals and pregnant mothers, could help identify PPD risks and reduce its prevalence. Objective: Given that awareness of PPD is a cr...

Background: Approximately 15 million children are born each year prematurely, representing more than 10 percent of all child-births worldwide. Prematurity is an acute event and the leading cause of death among newborns and children under five. Sixty percent of these premature deaths occur in Sub-Saharan Africa and Southeast Asia. Objective: The cur...

Objectives: Previous studies of a Cambodian birth cohort showed significant differences in birth weight, ponderal index and head circumference between newborns from two rural communities. The differences were associated with maternal anthropometrics and socioeconomic background, and the smallest babies were born to the mothers from the poorest comm...

The relationship between pesticide exposures and metabolomics biomarkers is not well understood. We examined the changes in the serum metabolome (early biomarkers) and the metabolic pathways associated with various pesticide exposure scenarios (OPE: overall exposure, PEM: exposure in months, PEY: exposure in years, and PEU: reported specific pestic...

Objectives Chronic lung disease is a recognized complication in children with HIV. Acute respiratory exacerbations (ARE) are common among this group and cause significant morbidity. Exhaled nitric oxide (eNO) is a known marker of local airway inflammation. We investigated the association between eNO and ARE, biomarkers of systemic inflammation, and...

Introduction: Chronic lung disease is a major cause of morbidity in African children with HIV infection; however, the microbial determinants of HIV-associated chronic lung disease (HCLD) remain poorly understood.

Plain language summary One of the major causes of maternal mortality is complications after abortion and miscarriages. The importance of post-abortion care in preventing such deaths justifies the necessity of making treatment accessible and available to every woman in need. Misoprostol is one of the approved treatments for incomplete abortion but i...

Background In Malawi, abortion is only legal to save a pregnant woman’s life. Treatment for complications after unsafe abortions has a massive impact on the already impoverished health care system. Even though manual vacuum aspiration (MVA) and misoprostol are the recommended treatment options for incomplete abortion in the first trimester, surgica...

Complications after abortion are a major cause of maternal death. Incomplete abortions are common and require treatment with surgical or medical uterine evacuation. Even though misoprostol is a cheaper and safer option, it is rarely used in Malawi. To improve services, an intervention was performed to increase the use of misoprostol in post-abortio...

Background Household contact tracing provides TB screening and TB preventive therapy (TPT) to contacts at high risk of TB disease. However, it is resource intensive, inconvenient, and often poorly implemented. We investigated a novel model aiming to improve uptake. Methods Between May and December 2014, we randomised patient with TB who consented...
