Growth DisordersOBJECTIVES: I. Evaluate the effect of bromocriptine on luteinizing hormone (LH) secretion by suppression of prolactin and stimulation of dopaminergic receptors in early pubertal boys and girls. II. Evaluate the effect of baclofen on LH secretion by stimulation of gamma-aminobutyric acid receptors in early pubertal boys and girls.
A New Measure of Egg Consumption and the Effect of Social Marketing Eggs
Nutritional StuntingAbout 1600 children 6 to 24 months old will be enrolled from 8 egg hubs. 4 hubs will be receive social marketing campaign to raise awareness about the benefits of eggs while the other 4 will not receive social marketing campaign. Children will provide a urine sample for analysis of metabolites to correlate with egg consumption.
The Sugira Muryango Longitudinal & Spillover Study
Cognitive ChangeGrowth; Stunting6 moreThe Early Childhood version of Sugira Muryango is a family-based, home-visiting intervention targeted at early childhood development and implemented with families living in extreme poverty in three districts of Rwanda. This version of Sugira Muryango was first tested in two small pilot studies and a large cluster randomized trial (CRT) was implemented between February 2018 and September 2019 . Pre- to post-intervention findings demonstrated that Sugira Muryango led to improvements in caregiver behaviors linked to child development and health as well as reductions in violence, which were sustained 12 months after the intervention, at which time improvements in child development were observed. The Research Program on Children and Adversity in the Boston College School of Social Work is led by Dr. Theresa S. Betancourt and will, in partnership with the University of Rwanda, FXB-Rwanda and Laterite, conduct a longitudinal follow-up study to investigate the longer-term outcomes of the Sugira Muryango intervention in families who participated in the CRT. The four-year follow-up will examine the long-term and sustained outcomes of the intervention. In particular, the investigators will look at key indicators of long-term positive outcomes for children such as school readiness and transition to formal schooling. Given the lack of longitudinal research on intervention programs supporting ECD in sub-Saharan Africa, this study will contribute greatly to the body of knowledge on the costs and benefits of investments in ECD and guide policy makers and government leaders on making impactful investments in children, leading to long-term benefits for the population at large. The follow-up study involves two activities: Activity A: Pilot to assess measures performance of newly added measures and field test study protocols. Activity B: Four-year follow-up of families who participated in the CRT of the Sugira Muryango intervention.
Bone Age Assessment in Children Using Ultrasound Compared to Wrist X-ray
Short StatureGrowth DisordersBone age assessment in children is based on the interpretation of hand x-ray scans according to Greulich and Pyle (GP) standard atlas and frequently used for evaluating growth and puberty in children and adolescents. To address the disadvantage of repeated irradiation, the need for specialized radiation centers, heavy equipment and subjective reading a new device, SonicBone was developed. SonicBone utilizes a quantitative ultrasonographic technology of ultrasonic (US) waves, propagating along a measured bone distance. The aim of the study is to evaluate an ultrasound based device, SonicBone, compared to the current method in children. The investigators will be compared the US assessment to available bone age X-ray that exists in the medical files of the patients. The investigators will not do bone age X-ray scans especially for the current study.
Early Versus Late Initiation of Feeding in Premature Growth Restricted Newborns With Absent or Reversed...
Prematurity of FetusPostnatal Growth DisorderThe purpose of the study is to compare early versus late initiation of enteral feeding in premature growth restricted babies below the gestational age of 35 weeks born to mothers with prenatal absent or reversal of end diastolic flow in the umbilical artery. Normally the blood flow from the mother to the baby brings all the nutrients required for growth and the very vital oxygen required for survival. These deprived babies with poor blood flow adapt to the not so conducive uterine environment by certain adjustments in blood supply to internal organs. This permits the best possible blood flow to brain heart etc., which are the vital organs and whose adequate functioning is required for survival. As a consequence, the gut (intestines) gets poor blood supply and hence its appropriate functioning may be jeopardized. Such 'premature growth restricted' babies are at increased risk of further growth faltering if not fed adequately as also to a condition called 'Necrotising enterocolitis' if fed liberally like other healthy neonates, characterized by abdominal distension, blood in stools and inability to feed for longer durations thereby further affecting growth. In the past such babies (after birth) were not fed for days together which compromised their growth even further. It is not clear whether continuing to withhold feeds for prolonged duration will prevent NEC but lead to growth faltering and initiating feeds early will potentiate NEC with further compromised growth and increased morbidity. There are no randomized trials on feeding strategies in this group of neonates and hence the investigators planned to carry out this study on comparison of early versus delayed initiation of feeding in preterm SGA infants with AREDF.
Safety and Efficacy of Long-term Somatropin Treatment in Children
Growth Hormone DisorderGrowth Hormone Deficiency in Children6 moreThis study is conducted in Europe. The aim of this study is to evaluate safety during the long-term use of somatropin (Norditropin®) in children as well as efficacy on change in height. A subgroup of children small for their gestational age is included.

Growth DisordersThe purpose of this study is to evaluate the effect of growth hormone treatment on phosphorus levels in the body. Phosphorus is an important mineral for bone growth. It is well known that growth hormone treatment improves bone density and bone mineral content. The amount of phosphorus is maintained by the kidneys. Fibroblast Growth Factor 23 has recently been recognized to help kidneys control phosphate levels.
