Filter by:Pregnant women at risk of giving birth before 28 weeks' gestational age will be enrolled. Fetal circulation will be studied and blood for inflammatory parameters will be collected. If birth occurs before 28 weeks, detailed information on clinical course of the newborn until discharge from the neonatal intensive care unit will be recorded,and specimens of amniotic fluid, placenta, blood and urine will be collection for inflammatory parameters. After discharge the children will be followed according to a specific protocol until 5 years of age.
In girls with elevated androgens the precise source of androgen excess throughout puberty and early adolescence has not been carefully examined. The investigators propose to examine whether the adrenal gland produces the majority of androgens during puberty by studying the differences in androgen responses to adrenocorticotropin hormone (ACTH) administration in normal weight (NW) and obese (OB) girls ages 7-18. The investigators' analyses will compare steroid changes before and 60 min after ACTH administration in NW and OB girls.
This study intends to observe the epidemiology of pregnancy and growth of adolescent mothers and their child in their first year on the development and growth ambulatory at Brasilia University Hospital (HUB). The study hypothesis is that adolescent growth is disturbed by a pregnancy in this age. Another hypothesis is that their child's growth and development could be obstructed.
Immediately following birth, preterm infants face a period of stressful environmental inputs, which may have negative consequences on early brain development and subsequent neurobehavioral outcomes. This study aimed to assess the effectiveness of training parents in reducing stressful experiences early in life. The investigators hypothesized that this intervention would insulate preterm infants from the harmful effects of acute and chronic stress, which in turn would result in enhanced brain development. The primary aim of the current study was to investigate if this intervention was associated with improved brain development measured by magnetic resonance imaging (MRI) at term-equivalent age. A secondary aim was to assess some possible short-term medical benefits.
Briefly our study is looking at the effects of 4 weeks of assisted exercise on the body composition and neurological/behavioral development of healthy growing premature infants enrolled between the ages of 30-33 weeks. It is a blinded study where the active group gets the exercise intervention and the control group is cuddled for the same amount of time -approximately 20 minutes. We get baseline data using muscle ultrasound, bone speed of sound and DEXA. We also get baseline blood samples to look at inflammatory mediators and growth hormone. Video of each subject is recorded an hour at two time points during the study to assess the babies for spontaneous activity. Nutritional intake information is collected daily and in the 4th week of the study assessments made for total energy expenditure using doubly labeled water. At this point in the study we repeat the ultrasounds and DEXA for comparison. Finally in the period just before discharge we do a complex neurological exam using the Brazelton NBAS assessment.
A molecular epidemiologic study of African American and Hispanic mothers and newborns to investigate the role of common urban pollutants on procarcinogenic and developmental damage.
