Background: Prenatal growth restraint associates with risk for later diabetes particularly if such restraint is followed by postnatal formula-feeding (FOF) rather than breast-feeding (BRF). Circulating incretins can influence the neonatal programming of hypothalamic setpoints for appetite and energy expenditure, and are thus candidate mediators of the long-term effects exerted by early nutrition.Objective, hypotheses and method: We have tested this conce...

Background: Infants born small-for-gestational age (SGA) who develop postnatal weight catch-up are at risk for insulin resistance, central adiposity and cardiovascular disease in later life, even in the absence of overweight.Objective and hypotheses: In young (age 3–6 years) non-obese SGA children, we assessed arterial health by intima-media thickness (IMT) and abdominal fat distribution (subcutaneous, visceral, pre-peritoneal and hepatic components...

Background: Hyperinsulinemic androgen excess is the most common cause of hirsutism, acne, seborrhea and menstrual irregularity in adolescent girls. The ovarian androgen excess originates most often from an absolute or relative excess of fat (in adipose tissue and in organs such as the liver) and from the ensuing elevations in insulinaemia and gonadotropin secretion. There is no approved therapy for androgen excess in adolescent girls. The prime recommendation is to reduce body...

Background: It is reported that children with congenital hypothyroidism (CH) are at increased risk of developing childhood obesity. Moreover, it is known that the timing of adiposity rebound (AR) in childhood is strongly linked with future obesity. Aims of our study were to explore the timing of AR and to identify factors affecting AR in a cohort of children with CH diagnosed by newborn screening and treated with levothyroxine. Design: one-center, retrospectiv...

Background: minipuberty (MP) consists in a postnatal activation of hypothalamic-pituitary-gonadal (HPG) axis, which occurs physiologically in both sexes during the first months of life. FSH and LH peak between 1 and 3 months, stimulating sex hormones secretion. In preterm infants, MP might lead to a stronger and more protracted hormonal stimulation, even if specific literature data are limited and not univocal. Immaturity of the hypothalamic feedback has been ...

Background: Heterozygous loss-of-function variants of fibroblast growth factor receptor 1 (FGFR1) are genetic causes of Combined Pituitary Hormone Deficiency (CPHD), Kallmann syndrome (KS) with anosmia/iposmia, Congenital Hypogonadotropic Hypogonadism (CHH) with normosmia and Septo-Optic Dysplasia. It is well-known that these variants are the main genetic factor underlying the development of CHH and KS; however, they have only occasionally been identified in C...

The accumulation of adipose tissue, especially visceral fat, represents a risk factor for reduced bone mineral density and spontaneous fractures. Several mechanisms have been proposed to explain the complex relationship between adipose tissue and bone. Obesity is associated with the production of inflammatory cytokines both by adipocytes and immune cells which may stimulate bone resorption and reduce bone strength. Studies in vitro and in vivo have reported t...

Introduction: Pubertal growth is hormone dependent. The anthropometric (height, weight) and sexual (Tanner stage (TS)) changes are accompanied by growth in foot length. However, the relationship between changes in foot length and other anthropometry remains unclear. Our aim was to determine how changes in foot length relate to growth parameters (height and weight), self-rated TS and serum sex steroids.Methods: We used data from the Adolescent Rural Cohor...

Background: An adrenal crisis (AC) is a life-threatening complication of congenital adrenal hyperplasia (CAH). Despite modern therapies, children with CAH still present with symptomatic adrenal insufficiency (AI) and AC.Objective and hypotheses: The aim of the study was to determine the spectrum of symptoms and signs of AI in children with diagnosed CAH who were admitted to hospital for an acute illness, as well as to evaluate the use of stress dosing an...

Background: Asprosin is an adipokine involved in glucose homeostasis and its plasma levels physiologically increases in fasting conditions and decreases with refeeding. In non-diabetic children and adolescents with obesity, insulin resistance (IR) and impaired fasting glucose (IFG) seem to influence the physiological variation in meal-related asprosin levels 120 minutes after an oral glucose load (Corica et al. doi:10.3389/fendo.2021.805700). No data ...
