Objectives: Innovations to improve public sanitation facilities, especially in healthcare facilities (HCFs) in low-income countries, are limited. SaTo pans represent novel, largely untested, modifications to reduce odour and flies and improve acceptability of HCF sanitation facilities. We conducted a pilot project to evaluate acceptability, cleanliness, flies and odour within latrines in 37 HCFs in Kisumu, Kenya, randomised into intervention (SaTo pan modifications) and control arms by sub-county and HCF level.

To evaluate outbreak response efforts, we conducted a household survey with drinking water testing in the five most affected wards in Dar es Salaam. We interviewed 641 households 6 months after the beginning of the outbreak.

Brain-blood communication is facilitated by intricate networks of brain vasculature, which display striking heterogeneity in structure and function. This vascular cell heterogeneity in the brain is fundamental to mediating diverse brain functions and has long been recognized.

Infected tubers are rendered unmarketable; hence, growers' profitability is adversely affected. Breeding for nematode resistance is a long-term process and phenotyping the segregating populations for nematode resistance is the most time-consuming and laborious part of the process.

Despite having distinct advantages, zebrafish have paralogs of many important genes, making reverse genetics approaches inefficient since generating animals bearing multiple gene mutations requires substantial efforts. Here, we present a simple and robust synthetic CRISPR RNA/Cas9-based mutagenesis approach for generating biallelic F0 zebrafish knockouts.

We compared maternal registry data during baseline and follow-up periods between public intervention and public control HCFs; we added seven private intervention HCFs and five private control HCFs to evaluate an unanticipated pilot insurance program that enabled women to use private intervention HCFs. From baseline to follow-up, ANC4+ visits and HCF deliveries in public intervention HCFs were 1.

Fenestrated, permeable brain vasculature mediates neuroendocrine function, body-fluid regulation, and neural immune responses; however, its vascular formation remains poorly understood. Here, we show that specific combinations of vascular endothelial growth factors (Vegfs) are required to selectively drive fenestrated vessel formation in the zebrafish myelencephalic choroid plexus (mCP).

In a cluster randomized trial in Vihiga district, western Kenya, we compared uptake of household water treatment with chlorine among six villages served by community vendors trained in standard social marketing plus education through listening (ETL), an innovative behavior change method, and six villages served by community vendors trained in standard social marketing only. Water treatment uptake, water quality, and childhood diarrhea were measured over 6 months and compared between the two groups of villages.

ANC and delivery services at health facilities, however, have been underutilized in Kenya. One potential strategy to increase the demand for ANC services is to provide health interventions as incentives for pregnant women.

To address this problem, a novel hollow fiber ultrafilter (HFU) was developed for household water treatment. To test its impact on water quality and infant health, we conducted a cluster-randomized longitudinal evaluation in 10 intervention and 10 comparison villages in Kenya, attempting to enroll all households with infants (< 12 months old).

In the Pacific Northwest, this virus is transmitted by the stubby root nematode (SRN) within the genus . Remediating CRS affected fields is a major challenge that can be mitigated by growing plant varieties that are resistant to TRV infection.

In response to this need, institutions and organizations around the world are developing research data science curricula to teach the programming and computational skills that are needed to build and maintain data infrastructures and maximize the use of available data. To date, however, few of these courses have included an explicit ethics component, and developing such components can be challenging.

In March 2011, the supporting international non-governmental organization transitioned management of the program to the Machinga District Health Office (DHO). We evaluated maternal and HIV service use before and after program transition to the DHO.

In 2011 and again in 2016, we interviewed staff in 26 randomly selected HCFs, observed water sources, water stations, and tested source and stored water for chlorine residual and . Of 26 HCFs, 22 (85%) had improved water supplies, and 22 (85%) had functioning handwashing and drinking water stations, but < 50% provided soap or water treatment.

Integrating water treatment and hygiene products into antenatal clinic care can motivate water treatment and handwashing among pregnant women. Free water hygiene kits (water storage containers, sodium hypochlorite water treatment solution, and soap) and refills of water treatment solution and soap were integrated into antenatal care and delivery services in Machinga District, Malawi, resulting in improved water treatment and hygiene practices in the home and increased maternal health service use.

This guideline aims to improve the care of these patients by standardizing diagnosis and treatment and incorporating up to date evidence-based research into practice. The primary objective of this study is to compare cases before versus after the implementation of the guideline to determine concrete effects the guideline has had in the care of patients with AHO and SA.

To address these problems, handwashing and drinking water stations were installed in 53 HCFs with prevention-of-mother-to-child-transmission of HIV programs in Kenya in 2005, and hygiene education was provided to health workers and clinic clients. To assess this program, we selected a random sample of 30 HCFs, observed the percentage of handwashing and drinking water stations that were functional and in use, and after that interviewed health providers and clients about hygiene and water treatment.

In 2009, in an integrated ANC/Preventing Mother-to-Child Transmission program, we provided free hygiene kits (safe storage containers, water treatment solution, soap, and oral rehydration salts) to women at their first ANC visit and refills at subsequent visits. To increase fathers' participation, we required partners' presence for women to receive hygiene kits.
