RESUMEN
PURPOSE OF REVIEW: Turner syndrome (TS), neurofibromatosis type 1(NF1), and William Syndrome (WS) are 3 genetic conditions that are all associated with a substantial increase in risk of hypertension. In this review, we focus on factors leading to hypertension and on clinical manifestations and management of hypertension in children and adolescents with these genetic conditions RECENT FINDINGS: In most instances, hypertension is secondary. There is a high prevalence of masked hypertension in TS; however, the extent to which control of the BP helps reduce the risk of aortic dissection/aneurysm in TS is not yet fully elucidated. Vasculopathies are the least emphasized but most important manifestation of NF1. Of note, routine screening for pheochromocytoma in NFI is not recommended as it is not cost-effective. Cardiovascular complications are the major cause of death in patients with WBS. ABPM identifies patients without overt aortic or renovascular narrowing. Antihypertensive agents such as ARBs that have direct vascular wall effects and agents that inhibit oxidative stress (minoxidil) should be considered, even in those who do not exhibit overt hypertension. Elevated blood pressure in children and adolescence manifests early with end-organ changes and when left untreated, increases risk for premature onset of cardiovascular disease. Vigilant monitoring of the blood pressure is recommended. Accurate early diagnosis and management of hypertension will delay or prevent target organ damage and ensure a healthier transition to adulthood among children afflicted with these conditions.

BACKGROUND: California law has standards for physical education (PE) instruction in K-12 public schools; audits found that the Los Angeles Unified School District did not enforce the standards. In 2009, the district adopted a PE policy to comply with these standards. PURPOSE: This study aimed to evaluate the outcomes of the PE policy in district schools. METHODS: PE class observations were conducted using the System for Observing Fitness Instruction Time in the 2010-2011 and 2011-2012 school years in an income-stratified random sample of 34 elementary, middle, and high schools to assess changes in PE class size, class duration, and time students spent in moderate to vigorous physical activity. RESULTS: PE class duration increased in high-income elementary schools. Mean class size decreased in low-income middle schools. CONCLUSIONS: There was limited implementation of the PE policy 2 years after passage. Opportunities exist to continue monitoring and improving PE quantity and quality.

Genetic forms of obesity contribute to â¼7% of severe obesity in children and adolescents. The exact global prevalence of monogenic and syndromic forms of obesity is not well established, most likely due to missed or delayed diagnosis. The challenge in determining the prevalence can be attributed to the lack of consensus on identifying and evaluating symptoms of genetic defects in a timely manner and hence a vastly undertested patient population. Further large-scale and long-term studies are needed to advance the understanding of this unique phenotype of obesity and effective treatment options."

One in five children and adolescents in the United States are diagnosed with obesity and nearly 6% of them are being classified under the severe obesity category. With over 7% of severe obesity being attributed to genetic disorders, in this review we aim to focus on monogenic and syndromic obesity: its etiology, wide spectrum of clinical presentation, criticalness of early identification, and limited management options. Advanced genetic testing methods including microarray and whole genome sequencing are imperative to identify the spectrum of mutations and develop targeted treatment strategies including personalized multidisciplinary care, use of investigational drugs, and explore surgical options in this unique subset of severe pediatric obesity.
RESUMEN
PURPOSE OF REVIEW: Approximately 2.6 million people die each year secondary to obesity related diseases. The risk of developing serious comorbidities depends on the age of onset as well as duration of obesity. In this review, we discuss trends in BMI trajectories from early childhood to adulthood with latest evidence on comorbidities in adulthood stemming from pediatric obesity and benefits of early intervention and treatment in childhood obesity. RECENT FINDINGS: Childhood obesity poses high risk of metabolic and cardiovascular disorders like type 2 diabetes, hypertension, atherosclerosis, coronary artery disease, and some types of cancer in adulthood. Early life obesity also increases risks of developing menstrual irregularities, infertility, and pregnancy complications. Several grave concerns including malignancies, autoimmune disorders, higher asthma morbidity, and psychiatric implications are found to be associated with childhood obesity. Disease outcomes can be transgenerational, causing suboptimal health in children of mothers with obesity. Encouragingly, many risks associated with childhood obesity can be reduced, delayed, or even reversed by early resolution of obesity necessitating close BMI monitoring and treatment early. SUMMARY: Early identification and aggressive management of childhood obesity is critical in prevention of debilitating comorbidities in adult life. VIDEO ABSTRACT: http://links.lww.com/COE/A19.

South Asians constitute one-fourth of the world's population and are distributed significantly in western countries. With exponentially growing numbers, childhood obesity is of global concern. Children of South Asian ancestry have a higher likelihood of developing obesity and associated metabolic risks. The validity of commonly used measures for quantifying adiposity and its impact on metabolic outcomes differ by race and ethnicity. In this review we aim to discuss the validity of body mass index (BMI) and other tools in screening for adiposity in South Asian children. We also discuss the prevalence of overweight and obesity amongst South Asian children in western countries and the differences in body fat percentage, adiposity distribution, and metabolic risks specific to these children compared to Caucasian children. South Asian children have a characteristic phenotype: lower lean mass and higher body fat percentage favoring central fat accumulation. Hence, BMI is a less reliable predictor of metabolic status in these children than it is for Caucasian children. Furthermore, the relatively lower birth weight and rapid growth acceleration in early childhood of South Asian children increase the risk of their developing cardiometabolic disorders at a younger age than that of Caucasians. We emphasize the need to use modified tools for assessment of adiposity, which take into consideration the ethnic differences and provide early and appropriate intervention to prevent obesity and its complications.
RESUMEN
Introduction: Rates of severe obesity in adolescents have increased at an alarming rate. Unfortunately, there are limited successful treatments for severe obesity in adolescents. Metabolic and bariatric surgery (MBS) is the most effective treatment available for adolescents with Class 2 and above severe obesity and has demonstrated variable degrees of sustained long-term weight loss which leads to resolution of multiple associated conditions and an improved quality of life.Areas covered: We discuss the current landscape of MBS in adolescents and evidence to support its long-term safety and efficacy. A literature search through PubMed, ResearchGate and HOLLIS Harvard Library Online Catalog was performed from the date of inception until 3/15/2021. A combination of the following keywords was used: Pediatric metabolic/bariatric surgery; long term outcomes of Pediatric metabolic/bariatric surgery, perioperative assessment, pediatric metabolic/bariatric surgery barriers; attitudes toward metabolic/bariatric surgery.Expert opinion: MBS is emerging as a safe and effective treatment strategy for adolescents with severe obesity, with recent studies demonstrating durable and sustainable weight loss. There remains an urgent need for longitudinal studies to assess durability of weight loss. Obesity stigma and bias, limited access to tertiary care centers, and skepticism around the treatment of obesity poses a major challenge.
