One of the objective methods of assessing the level of cardiopulmonary capacity in overweight and obese children and adolescents is cardiopulmonary exercise testing (CPET). The purpose of present study is an evaluation of aerobic capacity in high body mass index (BMI) children and adolescents by comparing them with a normal weight control group by CPET. The subjects were recruited from participants of the Program of Treatment for Overweight and Obese Children organized by a local pediatric rehabilitation center in Poland. Based on BMI for age and gender, two validation groups were selected: (1) a group of overweight children ( = 49) and (2) a group of obese children ( = 48). The study included also 53 normal weight participants as a reference group (REF). The study consisted of two parts: anthropometric measurements and CPET. The Godfrey protocol for CPET was applied. In this study, obese children and adolescents showed similar absolute VO values in liters per minute (1.64 L/min) compared to overweight children (1.48 L/min), but significantly higher than children with normal body weight (1.39 L/min). The obese children and adolescents presented lower VO in relation to body weight (25.44 ml/kg/min) compared to their peers with normal body weight (36.5 ml/kg/min), and overweight children (29.18 ml/kg/min). The main finding of our study was recognition of significant differences between cardiopulmonary capacity parameters in obese children in comparison not only to normal weight peers, but to overweight, too.

The association between self-reported total gestational weight gain by pre-pregnancy body mass index and moderate to late preterm birth.
BMC Pregnancy Childbirth

Department of Health Research Methods, Evidence, and Impact, McMaster University, Hamilton, ON, Canada.
Background: Inadequate and excessive gestational weight gain (GWG) defined by the Institute of Medicine (IOM) has been associated with preterm birth. However, studies demonstrate inconsistent associations.
Objectives: We examined the associations between categorical and continuous total GWG and moderate to late preterm birth (32-<37 weeks), and evaluated differences in these associations by pre-pregnancy BMI.

Article Synopsis
- Outdoor play is crucial for children's health and development, and ECECs can help provide this access.
- The PRO-ECO study tested an intervention designed to increase outdoor play in children aged 2.5 to 6 years across eight ECECs in Vancouver.
- Although the initial results showed no significant overall changes in outdoor play participation, there was a slight positive trend in the intervention group 6 months post-implementation, suggesting further research is needed to evaluate the intervention's effectiveness fully.
Parental impact on adherence of young children to 24-h movement behaviour guidelines: the Czech FAMIly Physical Activity, Sedentary behaviour and Sleep study.

Human movement behaviour typically unfolds in 24-h cycles, with children being additionally influenced by their parents. Therefore, the aim of this study was to investigate the adherence of 3-10-year-old children to the World Health Organization's (WHO) 24-h movement behaviour guidelines in relation to the behaviours of their mothers/fathers. Data from the Czech cross-sectional FAMIly Physical Activity, Sedentary behaviour and Sleep study included 381 families (with at least one child aged 3-10 years) from urban and rural areas across all three regions of Czechia.

Background: Bariatric surgery is the most effective intervention for severe pediatric obesity, but a subset of youth experience suboptimal weight loss and/or recurrent weight gain. Early re-initiation of obesity pharmacotherapy postoperatively may improve outcomes, though this has not been evaluated in pediatric populations.
Methods: A retrospective cohort study at a tertiary care children's hospital evaluated the safety and efficacy of reintroducing obesity pharmacotherapy within six weeks after laparoscopic sleeve gastrectomy (LSG).

The Cullin-3 E3 ligase adaptor protein SPOP targets proteins for ubiquitination and proteasomal degradation. We previously established the β-cell transcription factor (TF) and human diabetes gene PDX1 as an SPOP substrate, suggesting a functional role for SPOP in the β cell. Here, we generated a β-cell-specific deletion mouse strain ( ) and found that is necessary to prevent aberrant basal insulin secretion and for maintaining glucose-stimulated insulin secretion through impacts on glycolysis and glucose-stimulated calcium flux.
