Background: While differences in gut microbiota between obese and lean subjects have been described, few studies have examined how adiposity across childhood relates to intestinal microbiota composition and diversity in late adolescence.Objective: To explore the correlations between measures of adiposity from childhood and adolescence with intestinal microbiota composition and diversity at 15–17 years.Methods: Data stem from t...

Background: Dietary intake has been shown to influence the composition and diversity of the gut microbiota in adults, however its impact in childhood and adolescence remains uncertain. Moreover, the impact of other lifestyle behaviors such as physical activity, sedentary behaviors, sleep and fitness on the gut microbiota has rarely been investigated.Objective: To explore the correlations between intestinal microbiota composition and meas...

Background: Emerging evidence suggests a link between the intestinal microbiota and cardiometabolic outcomes in both children and adults. The oral microbiota is less studied, and the association between the oral microbiota and cardiometabolic health in childhood remains largely unknown.Objective: To explore the associations between oral microbiota diversity measured at 8-10 yr and cardiometabolic health in childhood and ...

Background: Oral microbiota composition and diversity differ between obese and non-obese individuals. However, the associations between lifestyle habits (implicated in the pathogenesis of obesity) and the oral microbiota remain uncertain, particularly among children.Objective: To explore the associations between oral microbiota diversity and lifestyle habits among 8-10 year-old children.Met...

Background: Published case reports and anecdotal experience suggest a positive effect of dexamphetamine on impetus and weight in patients with hypothalamic obesity.Objective and hypotheses: We aimed to observe these effects in our patients who are offered off-label treatment with dexamphetamine.Method: Between 2010 and 2013, patients starting dexamphetamine treatment were enrolled in a prospective observation study. BMI–SDS wa...

Background: Published case reports and anecdotal experience suggest a positive effect of dexamphetamine, a CNS stimulant on impetus and weight in patients with hypothalamic obesity. Based on these observations, patients presenting to our obesity clinic with hypothalamic obesity are offered off-label treatment with dexamphetamine.Method: Between 2010 and 2015, patients starting dexamphetamine treatment were enrolled in a prospective observation study. A r...

Increasing evidence suggests that the aetiology of disorders of sex development cannot be solely explained by genetic alterations. It is highly likely that environmental factors hitting susceptible genetic backgrounds are partly causative. Zebrafish sex is highly plastic during development, making this species an ideal model for investigation of endocrine disruption and gonadal development and function. However, the hormonal regulation of these processes in zebrafish is poorly...

Background: Leptin, primarily secreted by adipocytes, is a pivotal signal of the body's energy status and exhibits pleiotropic effects. Homozygous mutations in the leptin gene which result in defective synthesis, release or bioactivity, cause intense hyperphagia and early-onset severe obesity, along with multiple metabolic, hormonal, and immunological abnormalities. In vitro and animal model studies suggest that leptin plays a role in linear growth. So far...

Objective: Merge and standardize the scarce data on molecular and phenotypic findings of mutations in the human leptin receptor (LEPR) gene causing a rare form of severe early-onset obesity.Methods: We summarized functional and phenotypic traits of LEPR mutations reported in the literature in a structured and comprehensive manner. Additional data was obtained from 6 subjects of our outpatient clinic not reported so far. Functionality of mutations was ass...

Background: Disorders of carbohydrate metabolism in children and adolescents with cystic fibrosis occur from 5 to 12.6%, significantly increasing during the teenage period and reaching 24–50% in adults.Method: An analysis of 499 medical records was conducted. All the patients were treated in the Russian Children’s Clinical Hospital in 2012. The survey was carried out on carbohydrate metabolism and indications according to children after 12 year...
