This study uses a cross-sectional survey (n = 557) with a retrospective design to examine relationships between improvement in access to safe water supply (i.e. extension of municipal piped water) and a range of social outcomes including water insecurity, household time savings and allocation, and household water expenditure in Usoma, Kenya. Data were collected in July 2016, about 3 years after the intervention, using a modified version of the Household Water Insecurity Access Scale (HWIAS). Having assessed the validity and reliability of the modified HWIAS, we examine how differences in levels of access to safe water influence reported levels of water insecurity as well as amount of money and time savings, post the water intervention...

BACKGROUND: In vitro, animal, biological and observational clinical studies suggest that some hormonal methods, particularly depot medroxyprogesterone acetate - DMPA, may increase women's risk of HIV acquisition. DMPA is the most common contraceptive used in many countries worst affected by the HIV epidemic. To provide robust evidence for contraceptive decision-making among women, clinicians and planners, we are conducting the Evidence for Contraceptive Options and HIV Outcomes (ECHO) study in four countries with high HIV incidence and DMPA use: Kenya, South Africa, Swaziland, and Zambia (Clinical Trials...

Individuals living in malaria endemic areas become clinically immune after multiple re-infections over time and remain infected without apparent symptoms. However, it is unclear why a long period is required to gain clinical immunity to malaria, and how such immunity is maintained. Although malaria infection is reported to induce inhibition of immune responses, studies on asymptomatic individuals living in endemic regions of malaria are relatively scarce. We conducted a cross-sectional study of immune responses in asymptomatic school children aged 4-16years living in an area where Plasmodium falciparum and Schistosoma mansoni infections are co-endemic in Kenya...

BACKGROUND: Integration of family planning counselling and method provision into safe abortion services is a key component of quality abortion care. Numerous barriers to post-abortion family planning (PAFP) uptake exist. This study aimed to evaluate the effect of a quality management intervention for providers on PAFP uptake. METHODS: We conducted a pre- and post-intervention study between November 2015 and July 2016 in nine private clinics in Western Kenya. We collected baseline and post-intervention data using in-person interviews on the day of procedure, and follow-up telephone interviews to measure contraceptive uptake in the 2 weeks following abortion...

Objectives To establish exclusive breastfeeding (EBF) practice, women are encouraged to initiate breastfeeding of their newborns within one hour of delivery and breastfeed exclusively for the first 6 months of the infant's life. Research in Kenya has shown evidence of a reduced rate of EBF with an increase in socio-economic class (SES). This study explores the experiences of middle-income women so as to understand their attitudes and practices of EBF and to contribute toward the Baby Friendly Hospital (BFHI) and Baby Friendly Community Initiatives (BFCI) programs in Kenya...

Efforts have been made in recent years to improve knowledge about soil greenhouse gas (GHG) fluxes from sub-Saharan Africa. However, data on soil GHG emissions from smallholder coffee-dairy systems have not hitherto been measured experimentally. This study aimed to quantify soil GHG emissions at different spatial and temporal scales in smallholder coffee-dairy farms in Murang'a County, Central Kenya. GHG measurements were carried out for one year, comprising two cropping seasons, using vented static chambers and gas chromatography...

BACKGROUND: Malaria transmission reduction is a goal of many malaria control programmes. Little is known of how much mortality can be reduced by specific reductions in transmission. Verbal autopsy (VA) is widely used for estimating malaria specific mortality rates, but does not reliably distinguish malaria from other febrile illnesses. Overall malaria attributable mortality includes both direct and indirect deaths. It is unclear what proportion of the deaths averted by reducing malaria transmission are classified as malaria in VA...

INTRODUCTION: Current global helminth control guidelines focus on regular deworming of targeted populations for morbidity control. However, water, sanitation, and hygiene (WASH) interventions may also be important for reducing helminth transmission. We evaluated the impact of different potential helminth protective packages on infection prevalence, including repeated treatment with albendazole and praziquantel with and without WASH access. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cohort study nested within a randomized trial of empiric deworming of HIV-infected adults in Kenya...

In the western province of Nyanza in Kenya, girls and women face an issue all too common in the developing world-little or no access to affordable means to effectively managing their menstrual flow. As a result, many stay at home or drop out of school because they are teased and embarrassed. Some approach men for money to buy pads and are forced, in return, to engage in transactional sex. The girls may not be able to return to school at all due to pregnancy. The story literally and figuratively continues to cycle, keeping girls in positions of dependency and poverty...

Studies in urban informal settlements show widespread inappropriate infant and young child feeding (IYCF) practices and high rates of food insecurity. This study assessed the association between household food security and IYCF practices in two urban informal settlements in Nairobi, Kenya. The study adopted a longitudinal design that involved a census sample of 1110 children less than 12 months of age and their mothers aged between 12 and 49 years. A questionnaire was used to collect information on: IYCF practices and household food security...

BACKGROUND: Vector-borne diseases are increasingly becoming a major health problem among communities living along the major rivers of Africa. Although larger water bodies such as lakes and dams have been extensively researched, rivers and their tributaries have largely been ignored. This study sought to establish the spatial distribution of mosquito species during the dry season and further characterize their habitats along the Mara River and its tributaries. METHODS: In this cross-sectional survey, mosquito larvae were sampled along the Mara River, its two perennial tributaries (Amala and Nyangores), drying streams, and adjacent aquatic habitats (e...

BACKGROUND: The correct knowledge of standard case definition is necessary for frontline health workers to diagnose suspected diseases across Africa. However, surveillance evaluations commonly assume this prerequisite. This study assessed the knowledge of case definitions for health workers and their supervisors for disease surveillance activities in rural Kenya. METHODS: A cross-sectional survey including 131 health workers and their 11 supervisors was undertaken in two counties in Kenya...

BACKGROUND: Numerous studies have reported a strong association between temperature and mortality. Additional insights can be gained from investigating the effects of temperature on years of life lost (YLL), considering the life expectancy at the time of death. OBJECTIVES: The goal of this work was to assess the association between temperature and YLL at seven low-, middle-, and high-income sites. METHODS: We obtained meteorological and population data for at least nine years from four Health and Demographic Surveillance Sites in Kenya (western Kenya, Nairobi), Burkina Faso (Nouna), and India (Vadu), as well as data from cities in the United States (Philadelphia, Phoenix) and Sweden (Stockholm)...

BACKGROUND: The World Health Organization now recommends initiating all pregnant women on life-long antiretroviral therapy (ART), yet there is limited information about the characteristics and program outcomes of pregnant women already on ART in Africa. Our hypothesis was that pregnant women comprised an increasing proportion of those starting ART, and that sub-groups of these women were at higher risk for program attrition. METHODS AND FINDINGS: We used the International Epidemiology Databases to Evaluate AIDS- East Africa (IeDEA-EA) to conduct a retrospective cohort study including HIV care and treatment programs in Kenya, Uganda, and Tanzania...

The plant species Elaeodendron buchananii Loes is widely used in folklore medicine to manage microbial infections in Kenya. Previous studies on the plant fruits and root bark revealed the presence of steroids and terpenoids. The present phytochemical analysis of the plant stem bark has led to the isolation of four new triterpenes characterized as methyl 3β-acetoxy-11α, 19α, 28-trihydroxyurs-12-en-23-oic acid (1), 3β, 11α, 19α-trihydroxyurs-12-en-23, 28-dioic acid (2), 3β-acetoxy-19α, 23, 28-trihydroxyurs-12-ene (3) and 3-oxo-19α, 28-dihydroxyurs-12-en-24-oic acid (4), together with ten known ones (5-14), whose structures were elucidated using spectroscopic techniques...

An improved understanding of failure risks for water supplies in rural sub-Saharan Africa will be critical to achieving the global goal of safe water for all by 2030. In the absence of longitudinal biophysical and operational data, investigations into water point failure risk factors have to date been limited to cross-sectional research designs. This retrospective cohort study applies survival analysis to identify factors that predict failure risks for handpumps installed on boreholes along the south coast of Kenya from the 1980s...

This qualitative study examined the "drivers" of intimate partner violence (IPV) against women in displacement to identify protective factors and patterns of risk. Qualitative data were collected in three refugee camps in South Sudan, Kenya, and Iraq ( N = 284). Findings revealed interrelated factors that triggered and perpetuated IPV: gendered social norms and roles, destabilization of gender norms and roles, men's substance use, women's separation from family, and rapid remarriages and forced marriages. These factors paint a picture of individual, family, community and societal processes that exacerbate women's risk of IPV in extreme conditions created by displacement...

BACKGROUND: Sorafenib (SFN) is an anti-angiogenic chemotherapeutic that prolongs survival of patients with hepatocellular carcinoma (HCC); its side effects, including vascular damages such as hand-foot syndrome (HFS), are a major cause of therapy discontinuation. We previously reported that maintenance of peripheral blood flow by intake of dried bonito broth (DBB) significantly prevented HFS and prolonged the administration period. The amino acids contained in DBB probably contribute to its effects, but the mechanism has not been clarified...
