Stunting

This is an independent evaluation of World VIsion's 7-year quasi-experimental intervention to improve nutrition, nutrition-related rights and gender equality for women, adolescent girls, and children under five years of age in rural Bangladesh, Kenya, and Tanzania. The evaluation will collect baseline, midline, and end-line data from intervention communities, schools, and health facilities. Only baseline and endline will be collected on the comparison communities. The evaluation objectives are to test if the intervention improved indicators for (i) child anthropometry, (ii) maternal and child dietary practices, (iii) women's empowerment, and (iv) equitable health service access for nutrition and sexual and reproductive needs. The evaluation analysis will take into account gender differences in the indicators.

The association between nutrition in early life and its long-term health consequences has long been known. However, there is a scarcity of scientific evidence on how nutritional status affects child growth and development in remote, rural agro-pastoral communities with distinct dietary intake habits, geographical location, socio-economic status, and cultures.

Burden: Environmental Enteric Dysfunction (EED) is an enteropathic condition characterised by altered gut permeability, infiltration of immune cells, and changes in villous architecture and cell differentiation. EED is a major reason of malnourishment, poor neurological development, stunting, oral vaccine failure, and infection. It is believed that EED is responsible for 40% of all childhood stunting. Relevance: This trial aims to investigate the concept that a probiotic or live biotherapeutic product, capable of improving gut microbiota composition, can also displace enteropathogens and reduce biomarkers of intestinal inflammation, thereby promoting gut health. This will restore healthy microbial signalling to the host epithelium, ameliorate barrier function through secretion of mucus and antimicrobial factors, and improve nutrient availability. Objectives: The primary objective is to assess if administration of oral vancomycin followed by VE818 to pregnant women colonised with at least 2 out of 11 selected bacterial enteropathogens results in a significant change in the mean count of these organisms between the baseline and 2 weeks after completion of the intervention (Study Day 35d +2), compared to oral vancomycin followed by placebo. Methods: Pregnant women will be recruited from the community of Matiari in Pakistan. The study population will be women aged 18 years or older in the first trimester or early second trimester of pregnancy. Study procedures will be explained in detail, and written consent will be taken before enrollment. Those women who give consent to participation will undergo a screening process, which will check if any exclusion criteria are fulfilled. After consent and screening, they will be randomised into one of the three arms: intervention arm (oral vancomycin followed by VE818), placebo-control arm (oral vancomycin followed by placebo), or observation-only arm. The allocation sequence will be generated by the trial statistician using a code with block permutation. The participant will remain free to withdraw at any time from the trial without giving reasons and without prejudicing her further treatment. Biological samples, including blood, saliva, urine, stool, vaginal swab, and intestinal luminal contents through CapScan. CapScan is a non-invasive device (capsule) that collects gastrointestinal samples along the gastrointestinal tract following ingestion and passes into the stool. Outcome measures/variables: The primary endpoint is the change in the mean count in the number of 11 selected fecal bacterial pathogen groups present between baseline and 2 weeks after completion of the 14-day course with Placebo or VE818 (Study arms 2 and 3), which corresponds to the 35th day, +2 from the first dose of oral vancomycin. The 11 enteropathogen targets will be detected by customized real-time quantitative PCR-based TaqMan Array Cards (TAC-qPCR) and include the following organisms: Aeromonas, Campylobacter coli, Campylobacter jejuni, Campylobacter Pan, Enteroaggregative Escherichia coli (E. coli), Enteropathogenic E. coli, Enterotoxigenic E. coli, Plesiomonas, Shigella\_Enteroinvasive E. coli (EIEC), Salmonella, and Klebsiella pneumoniae

The aim of the study is to evaluate the impact of Benazir Nashonuma Program (BNP) on prevalence of stunting among under-five children in low income setting of Pakistan. The research question that the study aims to answer is: Is there any change in the prevalence of stunting among under-five children in districts where Benazir Nashonuma Program (BNP) is established compared to districts where BNP is not established? Districts where BNP is functional, and women and children are receiving the intervention will be compared at baseline and end line with control districts where conventional reproductive care services are given. Prevalence of stunting among under-five children will be compared along with other nutritional and growth status indicators over a period of 4 years.

The purpose of this study is to evaluate the impact of Benazir Nashonuma Program (BNP) which includes specialized nutritious food (SNF) augmented with specific reproductive health interventions during pregnancy on proportion of low birthweight babies and stunting among children, in low income setting of Pakistan. The study aims to answer if: 1. Utilization of Benazir Nashonuma Program (BNP) among pregnant women is effective in reducing the proportion of low birthweight babies, compared to pregnant women who are not utilizing the program, among low income setting population. 2. Utilization of Benazir Nashonuma Program (BNP) is effective in reducing the proportion of stunting among children, compared to those not utilizing the program, among low income setting population. Participants who are enrolled in the Benazir Nashonuma Program (receiving intervention) and those who are not enrolled (not receiving intervention) will be followed throughout pregnancy till delivery. After delivery mother-baby dyad will be followed for a period of 12 months. Compliance of supplementation will be measured, and outcomes (low birthweight and stunting) observed throughout the follow up.
