RESUMEN

The benefits of data sharing are well-established and an increasing number of policies require that data be shared upon publication of the main study findings. As data sharing becomes the new norm, there is a heightened need for additional resources to drive efficient data reuse. This article describes the development and implementation of the Data and Specimen Hub (DASH) by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) to promote data sharing from NICHD-funded studies and enable researchers to comply with NIH data sharing policies. DASH's flexible architecture is designed to archive diverse data types and formats from NICHD's broad scientific portfolio in a manner that promotes FAIR data sharing principles. Performance of DASH over two years since launch is promising: the number of available studies and data requests are growing; three manuscripts have been published from data reanalysis, all within two years of access. Critical success factors included NICHD leadership commitment, stakeholder engagement and close coordination between the governance body and technical team.

RESUMEN

OBJECTIVES: To determine the age of significant divergence in body mass index (BMI) and waist circumference in adults with and without the metabolic syndrome, and to provide age- and sex-specific childhood values that predict adult metabolic syndrome. STUDY DESIGN: Part 1 of this study is a retrospective cohort study of 92 men and 59 women (mean age, 51 years) who had metabolic syndrome and 154 randomly selected adults matched for age and sex who did not have the syndrome. Part 2 is a study of predictive accuracy in a validation sample of 743 participants. RESULTS: The first appearance of differences between adults with and without metabolic syndrome occurred at ages 8 and 13 for BMI and 6 and 13 for waist circumference in boys and girls, respectively. Odds ratios (ORs) for the metabolic syndrome at 30 years and older ranged from 1.4 to 1.9 across age groups in boys and from 0.8 to 2.8 across age groups in girls if BMI exceeded criterion values in childhood. The corresponding ORs for waist circumference ranged from 2.5 to 31.4 in boys and 1.7 to 2.5 in girls. These ORs increased with the number of examinations. CONCLUSIONS: Children with BMI and waist circumference values exceeding the established criterion values are at increased risk for the adult metabolic syndrome.

RESUMEN

The National Institute of Child Health and Human Development and the Digestive Diseases Interagency Coordinating Committee held a workshop, chaired by Dr. W. Allan Walker, on July 10-11, 2006, to identify promising leads in necrotizing enterocolitis (NEC) research. The goals of the workshop were to identify new approaches to the prevention and treatment of NEC, to define basic and translational mechanisms of potential approaches to NEC, and to develop recommendations for clinical studies to reduce the incidence of NEC. Workshop participants implicated prematurity, introduction of enteral feedings, gastrointestinal bacterial colonization, gut motility, proinflammatory cytokines, impaired gut blood flow, and various neonatal complications in the pathogenesis of NEC. They concluded that a unifying hypothesis encompassing these pathogenetic factors is the uncontrolled exuberant inflammatory response to bacterial colonization that characterizes the intestine of premature infants. The inflammatory cascade appears to offer multiple targets for interventions with a variety of anti-inflammatory agents, including human milk and probiotics. Because of the rapidity with which the inflammatory response gets out of control in infants with NEC, workshop participants agreed that searching for ways to prevent NEC will be more rewarding than trying to identify ways to treat the condition once it has become established.

RESUMEN

OBJECTIVE: The goal was to link hypertension and the metabolic syndrome in adulthood directly to blood pressures measured decades earlier for the same individuals as children and to establish criterion values for blood pressure that predict hypertension and the metabolic syndrome later in life. METHODS: We analyzed serial data for 240 men and 253 women in the Fels Longitudinal Study. We derived age- and gender-specific childhood blood pressures that predict hypertension and the metabolic syndrome in adulthood, and we validated these criterion values in a larger sample. RESULTS: Blood pressure diverged between adults with and without the metabolic syndrome beginning at age 5 for boys and age 8 for girls. The odds ratios for developing hypertension at > or = 30 years of age ranged from 1.1 for 14- to 18-year-old boys to 3.8 for 5- to 7-year-old boys and from 2.7 for 8- to 13-year-old girls to 4.5 for 5- to 7-year-old girls, if their blood pressure exceeded criterion values at a single examination in childhood. The corresponding odds ratios for the metabolic syndrome, with or without hypertension, ranged from 1.2 for 14- to 18-year-old boys to 2.6 for 8- to 13-year-old boys and from 1.5 for 14- to 18-year-old girls to 3.1 for 5- to 7-year-old girls. The relative risk of adult hypertension ranged from 1.5 to 3.8 for boys and from 1.5 to 4.7 for girls, and that of the metabolic syndrome ranged from 1.1 to 1.8 for boys and from 1.2 to 5.6 for girls. These relative risks varied directly with the number of examinations at which systolic blood pressure exceeded criterion values. CONCLUSION: Children with systolic blood pressures above the criterion values established in this longitudinal study are at increased risk of hypertension and the metabolic syndrome later in life.
