Our results showed that the discriminative value of Ret-Hb and sTfR for the detection of iron depletion is limited. Our findings suggest that ferritin is the most useful biomarker in the screening of iron depletion in healthy children in high-income countries. However, ideally, reference ranges of iron status biomarkers should be based on studies showing that children with concentrations outside reference ranges have poor neurodevelopmental outcomes.
Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare congenital disorder characterized by a dilated, non-obstructive urinary bladder and hypoperistalsis of the gastrointestinal tract, which is considered lethal. About 90 patients have been reported, predominantly female. We present the case of a female newborn with MMIHS in whom antenatal ultrasound was suggestive for the diagnosis, which was confirmed after delivery. Diagnostic features by antenatal ultrasound are described.
SummaryObjectiveThe objective of this research is to study effects of a 4‐week high‐protein (HP) diet on energy intake, resting energy expenditure (REE), protein turnover and body composition in children with obesity.MethodsIn this randomized placebo‐controlled single‐blind crossover study, children with obesity (n = 14; mean age: 10.1 years ± 1.2 standard deviation; body mass index–standard deviation score [BMI‐SDS]: 2.8 ± 0.5) received an ad libitum HP (+50 g protein per day) or normal‐protein (NP) diet for 4 weeks with a washout period of ≥2 weeks. Energy intake, REE, protein turnover, weight, BMI‐SDS and body composition were measured.ResultsNo differences were found in energy intake or REE between HP and NP. There was an increased urea production and phenylalanine hydroxylation after HP compared with NP (p < 0.05). There was an increased rise in fat‐free mass after HP compared with NP (∆HP: 0.8 ± 0.8 kg vs. ∆NP: 0.1 ± 0.6 kg, p < 0.05). BMI and BMI‐SDS increased during the study (BMI‐SDS start: 2.8 ± 0.5, end: 2.9 ± 0.5, p < 0.05) without a difference between groups.ConclusionsA 4‐week HP diet with ad libitum food intake did not affect energy intake and energy expenditure in children with obesity. BMI increased, although that could be partly explained by an increase in fat‐free mass.
Conclusions Female newborn infants have higher total and subcutaneous AT, but similar internal abdominal AT compared to males. Longitudinal study is required to assess gender specific alterations in AT distribution during infancy and childhood, and may identify possible influences of internal abdominal AT development in males.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
