Filter by:BCG vaccination may have non-specific effects (NSE) i.e., additional benefits on childhood morbidity and mortality that are separate the vaccine's effect on the incidence of disseminated tuberculosis. Though the available literature is mostly from observational study designs, and is fraught with controversy, BCG vaccination at birth, in a high risk population of HIV exposed children, may protect infants against serious infections other than TB. Yet, other studies indicate that giving BCG later in infancy, when the immune system is more mature, may offer even greater protection. The appropriate timing of BCG vaccination could therefore be up for revision. This study will therefore compare BCG vaccination at birth with BCG vaccination at 14 weeks of age in HIV exposed (HE) babies. Methods: This is an individually randomized clinical trial in 4,500 HIV exposed infants. The intervention is an intra-dermal administration of 0.05 ml of BCG vaccine within 24 hours of birth while the comparator will be an intra-dermal administration of 0.05ml of BCG vaccine at 14 weeks of age. The main study outcomes include: 1. Severe illness in the first 14 weeks of life, 2. Innate and adaptive immune responses to mycobacterial, non-mycobacterial antigens and TLR-agonists 3. Severe illness in the first 14-52 weeks and 0-52 weeks of life. The study will be carried in two health centers and one district hospital in Uganda. Implications: A well-timed BCG vaccination could have important additional benefits in HE infants. This trial could inform the development of programmatically appropriate timing of BCG vaccination for HE infants.
This is a matched-cohort study designed to assess the health impact of a rural demand-driven water and sanitation intervention that provides piped treated water and household level pour-flush latrines and bathing rooms, as implemented by Gram Vikas.
Malnutrition is considered one of the most prevalent risk factors for morbidity and mortality in children under five. An estimated 20% of children in the developing world are malnourished [1] and poor nutrition is linked to more than half of all child deaths worldwide [2]. Malnutrition in early childhood may lead to cognitive and physical deficits and may cause similar deficits in future generations as malnourished mothers give birth to low birth weight children [3]. In addition, malnutrition increases susceptibility and incidence of infections and is associated with diminished response to vaccines. The MAL-ED Project is designed to determine the impact of enteric infections/diarrhea that alter gut function and impair children's nutrition, growth and development to help develop new intervention strategies that can break the vicious enteric infection-malnutrition cycle and reduce its global burden. The overall objective of the MAL-ED Project is to quantify the associations of specific enteric pathogens, measures of physical and mental development, micronutrient malnutrition, gut function biomarkers, the gut microbiome, and immune responses in very young children in resource-limited settings across eight sites that vary by culture, economics, geography, and climate. The central hypothesis of the MAL-ED Project is that infection (and co-infection) with specific enteropathogens leads to impaired growth and development and to diminished immune response to orally administered vaccines by causing intestinal inflammation and/or by altering intestinal barrier and absorptive function. Data analyses will test for associations between enteropathogen infections and growth/development to help illuminate: - which micro-organisms or mixed infections are most frequently associated with growth faltering and poor development; and - at what age specific infections cause the most disruption to growth and development and impair immune response.
Children hospitalized with severe illness in sub-Saharan Africa are at high risk of morbidity and mortality following discharge from hospital. These children represent an accessible high-risk population in which targeted interventions to prevent morbidity and mortality could have dramatic impact. A large cluster randomized trial of azithromycin delivered in a mass drug administration program within trachoma endemic areas in sub-Saharan Africa demonstrated an almost 50% mortality benefit in children 1-9 years of age in treated communities. However, mass drug administration of azithromycin leads to the rapid emergence of macrolide resistance within treated communities and is expensive. The targeted delivery of azithromycin to children at hospital discharge may be a novel and practical intervention to maximize benefit while minimizing risk of antibiotic resistance. This is a randomized, double-blind, placebo-controlled trial to determine the efficacy of azithromycin provided at discharge, compared to placebo, in reducing mortality and re-hospitalization rates in children age 1-59 months in Kenya. The study will also investigate potential mechanisms by which azithromycin may reduce morbidity and mortality in this population and will assess the emergence of antibiotic resistance among treated individuals and their primary caregivers. A cost-effectiveness analysis of the intervention will also be conducted.
RATIONALE: Polymerized (cross-linked) sucralfate malate paste (ProThelial) may be an effective single therapy approach for the management of chemoradiation mucositis, treating and preventing its occurrence in the oral cavity, esophagus, stomach, small and large intestine. PURPOSE: This observational multi-phase trial is studying how well polymerized (cross-linked) sucralfate malate paste (ProThelial) works to prevent and treat mucositis in adult patients who are to receive or have received chemo/radiation therapy that have caused or is anticipated to cause mucositis in the oral cavity, esophagus, stomach, small or large intestine. The Phase IV study addresses prevention and treatment in the oral cavity. The Phase I study addresses prevention and treatment in the esophagus, stomach, small and large intestine.
This is a pilot study to assess the safety and immunogenicity of pentavalent rotavirus vaccine (RV5) when administered according to an alternate dosing schedule (2-5 weeks, 2 months and 4 months). In this interventional, open-label study, infants 2 through 5 weeks of age (14 to 41 days) will be enrolled and vaccinated with RV5 according to a 2-5 week, 2 and 4 month schedule and infants 2 months of age (56 to 83 days) will be vaccinated according to the standard recommended schedule (2, 4, and 6 months of age). Sera will be obtained from subjects one month following the final dose of vaccine and will be assayed for anti-rotavirus IgA and rotavirus neutralizing antibody responses against the G1, G2, G3, G4 and P[8] serotypes. Post dose 3 G1 serum-neutralizing antibody (SNA) geometric mean titers (GMTs) will be compared between children receiving pentavalent rotavirus vaccine (RV5) according to the alternate dosing schedule versus the standard recommended schedule. Likewise, post dose 3 G2, G3, G4 and P[8] SNA and serum rotavirus IgA GMTs will be compared between children receiving RV5 according to the alternate dosing schedule and the standard recommended schedule. The safety and tolerability of RV5 in children receiving vaccine according to the alternate dosing schedule will be described.
The incidence risk of colorectal cancer （CRC） is increasing at 4.2% year by year in China. Most effective way to reduce the death rate of CRC patients is to diagnose in quite an early stage. QiaoKou District is a chemical industry Zone of Wuhan with a long history, which has few data of CRC epidemiology. The investigators design the primary CRC screening for this district by healthy questionnaire, Fecal Occult Blood Test(FOBT) and colonoscopy. HanYang Areo has been chosen as Control for its non-industry environment.The crowd would be screen biennially. The high risk group would be intervened, such as resection of polyps or other specific treatment. A follow-up registration database has been built for analysis the relationship between incidence or death rate to high risk factors, such as age, life environment, lifestyles, base diseases and family history of cancer. This study will provide some epidemiology dates of CRC to the local Government, and assist the governor to built a more effective screening system of CRC.
Brief Summary: The purpose of this study is to measure the independent and combined effects of interventions that improve water quality, sanitation, hand washing, and nutrition on child growth and development in the first years of life.
