OBJECTIVE: To analyze and compare lung function of obese and healthy, normal-weight children and adolescents, without asthma, through spirometry and volumetric capnography. METHODS: Cross-sectional study including 77 subjects (38 obese) aged 5-17 years. All subjects underwent spirometry and volumetric capnography. The evaluations were repeated in obese subjects after the use of a bronchodilator. RESULTS: At the spirometry assessment, obese individuals, when compared with the control group, showed lower values of forced expiratory volume in the first second by forced vital capacity (FEV1/FVC) and expiratory flows at 75% and between 25 and 75% of the FVC (p<0...

OBJECTIVE: The Anti- Muellerian Hormone (AMH) has been reported as surrogate marker of antral follicles, which are the origins of hyperandrogenism in polycystic ovarian syndrome (PCOS). Therefore, AMH may be useful for the diagnosis of PCOS. The objective was to study the longitudinal changes in AMH concentrations in girls with and without PCOS. DESIGN: This is a longitudinal study of obese girls participating in a 1-year lifestyle intervention. PATIENTS: Forty obese girls aged 13-16 years (50% with PCOS) were included in the study...

While chronic systemic inflammation in obstructive sleep apnea (OSA) has been traditionally considered a consequence of intermittent hypoxia, several treatment studies targeting inflammation suggest that this process may precede the development of the disorder. A recent cross-sectional study in the Penn State Child Cohort (PSCC) revealed that inflammation largely mediates the association between visceral adiposity and OSA in adolescence. The purpose of this study was to examine for the first time whether, longitudinally, inflammation precedes OSA during this developmental period...

PURPOSE: Adolescent cigarette smoking has steadily declined since 1999, whereas adolescent obesity rates have quadrupled since the 1980s. Few studies address the longitudinal relationship of smoking and weight in youth and young adulthood. This study examines the relationship of smoking trajectories beginning in adolescence on weight status in young adulthood in a nationally representative longitudinal sample. METHODS: The study sample was drawn from the National Longitudinal Study of Adolescent to Adult Health Waves I-IV (N = 13,361)...

BACKGROUND: During 2016, approximately 140,000 individuals entered the United States as part of the federal government refugee resettlement program and established themselves in communities in virtually every state. No national database regarding refugee health currently exists; therefore, little is known about existing infectious diseases, conditions, and cultural practices that impact successful acculturation. The objective of this report is to identify what is currently known about refugees and circumstances important to infection prevention and control with respect to their roles as new community members, employees, and consumers of health care...

The oral health of children and adolescents mirrors their general health. Because oral health care is often delivered in isolation from general health care, oral signs and symptoms do not always alert practitioners to their significance beyond the mouth. An important example of this is the association of a higher risk of dental caries and periodontal disease in children and adolescents with overweight, obesity and prediabetic conditions. Oral-health practitioners need to consider the health conditions that their patients may have...

BACKGROUND: Emerging experimental evidence suggests that air pollution may contribute to development of obesity and diabetes, but studies of children are limited. OBJECTIVES: We hypothesized that pollution effects would be magnified after bariatric surgery for treatment of obesity, reducing benefits of surgery. METHODS: In 75 obese adolescents, excess weight loss (EWL), high-density lipoprotein (HDL) cholesterol, triglycerides, alkaline phosphatase (ALP) and hemoglobin A1c (HbA1c ) were measured prospectively at baseline and following laparoscopic adjustable gastric banding (LAGB)...

INTRODUCTION: The onset of obesity at young ages is strongly associated with the early development of type 2diabetes (T2D). The shape of the curves of glucose and insulin curves during an oral glucose tolerance test (OGTT) could predict the risk of developing T2D. OBJECTIVE: To analyse the morphology of the OGTT and determine T2D risk factors in a mainly Caucasian population of children and adolescents. METHODS: Observational retrospective study including 588 patients (309 males, 279 females) with a mean age of 11...

BACKGROUND: Lower levels of physical activity and cardiorespiratory fitness are key risk factors of chronic adult diseases. Physical activity and cardiorespiratory fitness are predicted by birth weight, but the underlying parental and pregnancy-related factors remain largely unknown. We examined how prenatal determinants are associated with physical activity and cardiorespiratory fitness in adolescence. METHODS: Of the 16-year-old members of the population-based Northern Finland Birth Cohort 1986 (NFBC 1986), 6682 singletons with no major physical disability reported their amount of physical activity outside school hours, and 4706 completed a submaximal cycle ergometer test assessing cardiorespiratory fitness...

RATIONALE: Hepatic steatosis develops after liver transplant in 30% of adults, and non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in non-transplanted children. However, post-transplant steatosis has been minimally studied in pediatric liver transplant recipients. We explored the prevalence, persistence, and association with chronic liver damage of hepatic steatosis in these children. RESULTS: In this single-center study of pediatric patients transplanted 1988-2015 (n=318), 31% of those with any post-transplant biopsy (n=271) had ≥1 biopsy with steatosis...

REVIEW
W Allan Walker
The fetus does not reside in a sterile intrauterine environment and is exposed to commensal bacteria from the maternal gut/blood stream which crosses the placenta and enters the amniotic fluid. This intestinal exposure to colonizing bacteria continues at birth and during the first year of life and has a profound influence on lifelong health. Why is this important? Intestinal crosstalk with colonizing bacteria in the developing intestine affects the infant's adaptation to extrauterine life (immune homeostasis) and provides protection against disease expression (allergy, autoimmune disease, obesity, etc...
