Coupons for Safe Water Project
DeathDeath6 moreGuaranteeing access to safe drinking water is still a challenge in rural households in developing countries, and unsafe water sources are responsible for millions of deaths each year around the world. Coupons for free dilute chlorine solution are a cost-effective and effective way of ameliorating child health and reducing diarrhea incidence. It is still an empirical challenge, however, to see if the positive health effects will be maintained when the program is implemented at scale. In this study, investigators conduct a randomized controlled trial (RCT) at scale to study the impacts of a chlorine coupon program implemented at health clinics on child health, including self-reported diarrhea, fever, and cough incidence in the previous two weeks. Investigators further investigate the pathway of the impact, such as self-reported and objectively measured use of chlorine and frequency of visits to health clinics.
Trial to Compare BCG-Bulgaria and BCG-Denmark
Death; NeonatalDeath4 moreThe trial will be a two-year outcome assessor-blinded RCT at the maternity ward of Hospital Simão Mendes (HNSM) in urban Bissau, Guinea-Bissau to compare vaccination with Bacillus Calmette-Guérin (BCG) Danish strain (AJ Vaccines, Copenhagen 1331 strain) versus BCG-Bulgaria (BB-NCIPD, BCG-SL 222 Sofia strain) 1:1 in 15,000 infants with respect to mortality, morbidity and case-fatality rate during hospital admission. The trial will also examine the association between BCG strains and BCG skin reaction kinetics and characteristics. As a secondary aim, this large study will be used to further evaluate the role of maternal BCG immune priming for overall health, since there are indications that the maternal BCG scar status influences offspring health outcomes.
Can BCG Vaccination at First Health-facility Contact Reduce Early Infant Mortality?
Infant MortalityBCGBacillus Calmette-Guérin (BCG) vaccination is recommended at birth to protect against tuberculosis (TB) in countries with high TB burden. BCG is supplied in multidose vials with limited durability after reconstitution. In Guinea-Bissau, this has led to a practice of only opening a BCG vial at specific days, and only if sufficient children are present. Therefore, BCG vaccination is frequently delayed. Accumulating evidence indicates that BCG has beneficial effects on survival beyond the specific protection against tuberculosis, so called non-specific effects (NSEs). The hypothesis of this study is that increasing the availability of BCG and vaccinating children at the first health-facility contact can reduce early infant non-accidental mortality by 25%. In a cluster-randomised crossover trial, 23 health facilities (HFs) in three rural regions in Guinea-Bissau will be randomised to either continue with current practice (typically BCG vaccination once a week if a sufficient number of children are present for vaccination); or to offer additional BCG vaccines to make BCG available every day and open a vial of BCG if there is just one eligible child present. All children born in the three regions and registered during the study period, will be eligible for inclusion into the trial 1 day after birth. If consent is given by the mother, the child will be followed until day 42 after birth, when other vaccines are scheduled to be given. The primary outcome will be non-accidental mortality, secondary outcomes are non-accidental hospital admissions, non-accidental neonatal mortality and cost-effectiveness of making BCG available at the first health-facility contact.
Oral Azithromycin to Prevent Stillbirths and Infant Mortality in Mali
Stillbirths and Infant MortalityThe double blind randomized controlled trial will assess the efficacy of oral azithromycin administered to pregnant women and/or infants during routine care in preventing stillbirths and mortality through 6-12 months of age in Mali, West Africa, where rates of infant and under five mortality are among the highest in the world.
Trial to Compare Two Strains of BCG
DeathInfant1 moreThe trial will be a two-year outcome assessor-blinded RCT at the maternity ward of hospital Simão Mendes (HNSM) in urban Bissau, Guinea-Bissau to compare BCG-Japan versus BCG-Russia 1:1 in 15,000 infants with respect to mortality, morbidity and case-fatality rate during hospital admission. The trial will also examine the association between BCG strains and BCG skin reaction characteristics by six weeks (data collected by telephone) and at two and six months (data collected at home-visits to a subgroup of the cohort). As a secondary aim, this large study will be used to further evaluate the role of maternal BCG immune priming for overall health, since there are indications that maternal BCG scarring enhances the non-specific effects of BCG.
Improving Pediatrician Counseling About Infant Safe Sleep Using the Electronic Medical Record
Sudden Infant DeathSudden Unexplained Infant DeathThe study team will evaluate the impact of an Infant Sleep Assessment (ISA) tool with motivational interviewing (MI) communication training on clinician-parent communication during 2-month Well Baby Visits (WBV) and parent reported and observed infant sleep practices. The study team's hypotheses are that 1) clinicians who utilize the ISA with MI training will more effectively communicate safe sleep information to their patients' parents, and 2) these parents will have safer infant sleep practices than parents whose clinicians are in a standard of care control group.
Apparent Life Threatening Events, Sudden Infant Death Syndrome and Muscarinic Receptors
Apparent Life-Threatening Event in Infants Under One Year of AgeApparent Life-Threatening Events (ALTE) in infants often lead to severe neurological complications or to sudden death. In such situations, cardio-pediatricians and intensive care physicians have no specific diagnosis or treatment. In a recent translational research (INSERM-DHOS), our team has reported a myocardiac abnormality in a rabbit model of vagal hyperreactivity which is also present in the human hearts of infants deceased from sudden death, i.e. increased M2 muscarinic receptors (M2R) density associated with compensative increased enzymatic activity and overexpression of acetylcholine esterase (AchE). In a recent PHRC-I study (article in preparation), these abnormalities have also been observed in the blood of patients, infants as well as adults, exhibiting severe vagal syncopes. We observed, even more importantly, similar abnormalities in infants under 1 year of age with very severe idiopathic ALTE (iALTE) compared with normal subjects and with patients who presented ALTE with identified etiologies (JAMA Pediatric, 2016 May). The aim of this present study is to validate the overexpression of M2R as a marker of risk of iALTE in infant under 1 year.
The Effect of Video-Assisted Sudden Infant Death Syndrome Prevention Training Program and Counseling...
Sudden Infant DeathSudden Infant Death Syndrome (SIDS) is one of the leading causes of infant mortality in the postneonatal period, but it can be prevented and its incidence can be reduced by creating a safe sleep environment with modifiable risk factors. It is known that parents, infant care providers and healthcare professionals do not have sufficient knowledge about SIDS and safe sleep, and especially mothers exhibit many risky behaviors in terms of SIDS, such as using the wrong sleeping positions while putting their babies to sleep. Therefore, it is of critical importance to inform and raise awareness of parents on the issues of SIDS and safe sleep, which remain important today, on the premise of promoting public health.
Incorporation of Safe Sleep Education Into m-Health Technology
Sudden Infant DeathSudden Unexplained Infant Death (SUID) is the leading cause of death in infants age 28 days to 1 year. Protective factors, such as supine positioning, firm sleep surface, breastfeeding, pacifier use, elimination of soft objects from the sleep space, and avoidance of tobacco, alcohol, and illicit drugs have been shown to decrease the risk. The American Academy of Pediatrics recommends that healthcare providers model and convey safe sleep practices during patient encounters. Pediatric emergency departments (PED) serve as front-line contact for populations at greatest risk for SUID, however few interventions have been tested in the PED setting. M- Health (mobile health) apps have previously demonstrated the ability to deliver safety education to parents and are well suited for use in the PED given limited clinician time and long wait times. Safety in Seconds (SIS) is a theory based, m-Health injury prevention tool focused on care seat safety and fire safety with previously demonstrated effectiveness in an NIH-funded randomized trial. This study aims to add safe sleep education into the SIS, and subsequently disseminate the app in the PED setting. Integration of safe sleep education into SIS represents an opportunity to increase safe sleep knowledge and practices through a proven effective m-Health intervention. This study addresses this potential by incorporating a previously developed, theory-driven and evidence-based safe sleep education into the SIS app and testing the feasibility of deployment in the PED.
Fetal Electrophysiologic Abnormalities in High-Risk Pregnancies Associated With Fetal Demise
High Risk PregnancyCongenital Heart Disease16 moreEach year world-wide, 2.5 million fetuses die unexpectedly in the last half of pregnancy, 25,000 in the United States, making fetal demise ten-times more common than Sudden Infant Death Syndrome. This study will apply a novel type of non-invasive monitoring, called fetal magnetocardiography (fMCG) used thus far to successfully evaluate fetal arrhythmias, in order to discover potential hidden electrophysiologic abnormalities that could lead to fetal demise in five high-risk pregnancy conditions associated with fetal demise.
