Acute gastroenteritis remains a common illness among infants and children throughout the world. Among children in the United States, acute diarrhea accounts for >1.5 million outpatient visits, 200,000 hospitalizations, and approximately 300 deaths/year. In developing countries, diarrhea is a common cause of mortality among children aged <5 years, with an(More)
HIV infection can contribute to disturbances in both linear growth and weight gain in early childhood, with disturbances often apparent as early as 3 months of age. There is little evidence for a difference in the early growth of HIV-exposed but uninfected children compared to healthy controls. Owing to the close association of growth with immune function(More)
BACKGROUND The International Serial Transverse Enteroplasty (STEP) Data Registry is a voluntary online database created in 2004 to collect information on patients undergoing the STEP procedure. The aim of this study was to identify preoperative factors that are significantly associated with transplantation or death or attainment of enteral autonomy after(More)

AIM To evaluate the vitamin B(12) status of South Indian women in early pregnancy and its relationship with sociodemographic, anthropometry and dietary intake. METHODS Cross-sectional study among 366 pregnant urban South Indian women ≤14 weeks of gestation with outcome variables defined as low vitamin B(12) blood concentration (<150 pmol/l) and impaired(More)
Changes in small bowel function early in infancy in developing countries are increasingly being demonstrated, probably accompanied by altered mucosal architecture in most individuals, including reduced enterocyte mass and evidence of immune activation and inflammation in the mucosa. These alterations appear to be the result of factors of uncertain nature in(More)
OBJECTIVE The objective was to determine the safety and efficacy of a fish oil-based intravenous lipid emulsion (ILE) in the treatment of parenteral nutrition-associated liver disease (PNALD). SUMMARY AND BACKGROUND DATA PNALD can be a lethal complication in children with short bowel syndrome (SBS). ILE based on soybean oil administered with parenteral(More)
BACKGROUND Protein-energy malnutrition is common among infants with congenital heart disease. We hypothesized that infants with hypoplastic left heart syndrome (HLHS) are at risk for malnutrition. OBJECTIVE To determine the prevalence of and risk factors for malnutrition in infants undergoing palliative surgery for HLHS. METHODS Retrospective chart(More)
Epithelial and other cells of the gastrointestinal mucosa rely on both luminal and bloodstream sources for their nutrition. The term functional food is used to describe nutrients that have an effect on physiologic processes that is separate from their established nutritional function, and some of these nutrients are proposed to promote gastrointestinal(More)
PURPOSE Pediatric short bowel syndrome (SBS) remains a management challenge with significant mortality. In 1999, we initiated a multidisciplinary pediatric intestinal rehabilitation program. The purpose of this study was to determine if the multidisciplinary approach was associated with improved survival in this patient population. METHODS The Center for(More)
Stunting is common in young children in developing countries, and is associated with increased morbidity, developmental delays, and mortality. Its complex pathogenesis likely involves poor intrauterine and postnatal nutrition, exposure to microbes, and the metabolic consequences of repeated infections. Acquired enteropathy affecting both gut structure and(More)
