Background: Transgender individuals increasingly present at gender services in childhood. Consequently, to suppress pubertal development, more adolescents are long-term exposed to gonadotropin-releasing hormone analogues (GnRHa), from onset of puberty until start of gender-affirming hormones (GAH), around 16 years. Prolonged GnRHa may compromise bone health more than shorter-term treatment. If earlier start of GAH, when psychologically indicated, may partially...

Introduction: Bone fragility or predisposition to fractures with low-impact energy is a rare but potentially limiting condition. Variations in PLS3 gene are a cause of monogenic osteoporosis due to the alteration of osteoclast and osteocyte function and bone mineralization. It is characterized by early-onset osteoporosis, peripheral fractures, vertebral compression fractures and thoracic kyphosis. Due to its X-linked inheritance, the phenotype is more severe i...

Background: Low bone mineral density (BMD) has been found in up to 50% of adolescents and adults with Prader-Willi syndrome (PWS). High fracture risk has been described in adult PWS patients. However, the mechanism/s of low BMD in PWS have not been clarified. These patients also display high BMI-SDS that prompted us to evaluate the levels of LIGHTTNFSF14, a cytokine involved in pathological bone remodeling and obesity.Objecti...

Introduction: BIPSS before and after desmopressin stimulation has been shown to be a useful tool for diagnosis of ACTH-dependent CD and negative magnetic resonance imaging (MRI)or positive MRI but inconsistent biochemical data, in adult patients. However, little is known about its usefulness in pediatric population.Objective: To evaluate the prevalence of negative MRI, the sensitivity of BIPSS before and after desmopress...

Introduction: Maternal caloric restriction during gestation leads to offspring’s metabolic programming through epigenetic changes, which increase the risk of developing cardiovascular diseases in adulthood.Objectives: To study in a swine animal model: i) DNA methylation changes associated with caloric restriction during gestation in the adipose tissue of the offspring; and ii) the reversibility of these changes by metformin treatment.<p class="a...

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...

Background: Early catch-up growth, between birth and age two years, in infants born small-for-gestational-age (SGA) is a risk factor for the development of cardiometabolic diseases in adulthood. The basis and mechanisms underpinning catch-up growth in SGA newborns are unknown.Objectives: We aimed to investigate the catch-up predictive ability of cord blood miRNAs in SGA infants.Methods: MicroRNA PCR Human Panels were used to study ...

Background: The placenta plays a key role in regulating fatty acid (FA) transport from maternal to fetal circulation. An unfavourable FA profile in the placenta, reflecting an inadequate nutritional status during pregnancy, may cause changes in placental DNA methylation and negatively affect fetal growth and metabolic health of the offspring.Objectives: We aimed to study the association of an unfavourable placental FA profile with placental DNA methylati...

Introduction: Quality of life (QoL) is a multidimensional indicator including several functions and represents an important evaluator of patient’s health, especially in chronic diseases. Treatment with aGnRH in Central Precocious Puberty (CPP) is source of stress for patients and families. The aim of our study is to evaluate QoL and levels of therapy-related stress in patients with CPP and in their families during and after treatment.Material and me...

Background: Type 1 diabetes (T1DM) is associated with low bone mineral density (BMD) and bone alterations, probably due to lack of insulin and chronic hyperglycemia. Sclerostin and Dickkopfs-1 (DKK-1) are Wnt signaling inhibitors involved in bone remodelling.Objective and hypotheses: To assess serum levels of DKK-1 and sclerostin in T1DM children and adolescents on continuous subcutaneous insulin infusion (CSII) or multiple daily therapy (MDI). We hypoth...
