Long-Term Effects of a Ketogenic vs a Hypocaloric Diet in Children and Adolescents with Obesity

Partsalaki Ioanna , Karvela Alexia , Spiliotis Bessie E

Background: The prevalence of childhood obesity is high worldwide and predisposes to adult obesity and metabolic disorders. Many dietary approaches have been proposed to reduce this prevalence, but no single diet has proven to be superior to others in terms of long-term weight loss maintenance in children.Objective and hypotheses: To evaluate and compare long-term body weight changes among obese children and adolescents who had lost at least 10% of their...

Children with Type 1 Diabetes and Obesity show biochemical changes associated with insulin resistance

Hayes Eadaoin , Cody Declan , E Hogan Andrew

Children with Type 1 diabetes are experiencing higher levels of overweight and obesity as a consequence of intensive insulin therapy as well as background socioeconomic and environmental factors that are contributing to excess adiposity in the general population. The consequences of obesity in people with type 1 diabetes are of particular concern, as obesity in adults increases the risk of both diabetes-related and obesity-related complications, including cardiovascular diseas...

Pubertal timing and characterization in children with congenital hypothyroidism: How important is preschool age anthropometry?

Güven Ayla , Nurcan Cebeci Ayşe

Introduction: The main purpose of the study was to determine whether anthropometric measurements at preschool (PS)-age, in which physiological adiposity rebound is detected, and LT4 dose have an effect on the age of onset of puberty in children with hypothyroidism.Methods: This is an observational and retrospective study.Results: Puberty had begun in 44 girls and 25 boys out of 115...

Paediatric Patients with Type 1 Diabetes Mellitus Exhibit Reduced Brown Adipose Tissue Heat Signature Following Cold Stimulation

Law James , Morris David E. , Robinson Lindsay , Randell Tabitha , Denvir Louise , Symonds Michael E. , Budge Helen

Brown adipose tissue (BAT) is a key component of the body's defence against cold challenge and possesses the ability to convert large amounts of chemical energy to heat, conferred by a unique protein, uncoupling protein (UCP)-1, diverting mitochondrial respiration from the production of adenosine triphosphate. In humans, the largest BAT depot is in the supraclavicular region. Sympathetic nervous system stimulation induces glucose uptake into brown adipose tissue, as does i...

GH Unmasked Laryngomalacia and worsened Obstructive Sleep Apnea in Infants with Prader-Willi Syndrome

Salehi Parisa , Wrede Joanna E , Johnson Kaalan E , Chen Maida L

Background: Prader-Willi Syndrome (PWS), due to loss of paternal gene expression on chromosome 15q11.2-13, is characterized by hypotonia, hypothalamic-pituitary dysregulation, abnormal respiratory drive, and hyperphagia. GH, often started in infancy, improves tone, body composition, and height. Concerns about sudden death in children with PWS started on GH, hypothesized secondary to worsening obstructive sleep apnea (OSA) from adenotonsillar hypertrophy, resulted in guidelines...

Butyrate Stimulates GH Secretion From Rat Anterior Pituitary Cells Via the G-Protein-Coupled Receptors GPR41 and 43

Miletta Maria Consolata , Petkovic Vibor , Eble Andree , Ammann Roland , Fluck Christa E , Mullis Primus E

Background: Butyrate is a short-chain fatty acid closely related to the ketone body β-hydroxybutyrate (BHB) considered as the major source of energy during prolonged exercise. During fasting, when the liver switches to fatty acid oxidation, a rise in serum GH occurs concomitantly with the accumulation of BHB and short chain fatty acids (SCFA) acetate, propionate and butyrate. Interactions between GH, ketone body and SCFA during the metabolic adaptation to fasting are poor...

Pediatric transgender care from an endocrine perspective: experience over the past decade in a tertiary Swiss center

Mazzi Sara , Nussbaum Marie-Lou , Christa Flück E.

Gender dysphoria indicates a psychological distress due to any incongruence between biological sex and gender identity, while transgender identity refers to an individual, whose gender identity is the opposite of the biological sex. The number of gender dysphoric youth seeking hormonal care seems to rise worldwide. Therefore, numerous bioethical and medical controversies are raising about possible side effects of hormonal therapies, including interference with brain developmen...

Metformin Treatment Affects ACTH Receptor Activation and Downstream Signaling: A Potential Treatment for ACTH Excess Disorders and Management of Hyperandrogenic States

Parween Shaheena , Pandey Amit V. , Flueck Christa E.

Background: The peptide hormone adrenocorticotropin (ACTH or Corticotropin) is a major component of the stress response system in the Hypothalamus-Pituitary-Adrenal (HPA) axis. Under stress, it is secreted from the anterior pituitary and stimulates cortisol production from the adrenal cortex. Changes in ACTH production or action are associated with multiple disease conditions. In clinical situations like Cushing's disease, ectopic ACTH syndrome and congeni...

Virilization of a Girl at Puberty Due to a Unique Translocation of an Abnormal Duplicated Y-Chromosome to a Deleted Chromosome 9 Including the DMRT1 Gene

Graf Stefanie , Aliu Nijas , Zeino Mazen , Flueck Christa E.

Background: Virilization at puberty in girls remains a challenge. Several differential diagnoses must be considered including disorders of sex development (DSD) and tumors.Case Report: We report an 11.5-year-old girl who was referred to our center for progressive cliteromegaly since 6 months. Past medical history was remarkable for prematurity of 36 weeks gestation and for mild ongoing psychomotor delay. At presentation ...

Contraceptives in Female Adolescents with 21-hydroxylase Deficiency (CAH) - a way to Optimize Treatment with Respect to Androgen Excess? A Pilot Study

Boettcher Claudia , Graf Stefanie , Flück Christa E

Background: At present, treatment of „classic" congenital adrenal hyperplasia (21-hydroxylase-deficiency, 21OHD) consists of glucocorticoid and mineralocorticoid replacement. However, often androgen excess and its negative metabolic impact are difficult to control without accepting glucocorticoid overtreatment, especially in adolescence. In healthy subjects oral contraceptives (containing ethinylestradiol) increase cortisol binding capacity and free c...
