Background: Puberty onset results from the interplay between genetic and environmental factors. During COVID-19 pandemic, children experienced epidemic-related changes, such as stress, sedentary lifestyle, excessive use of electronic devices, all leading to weight gain.Objective: The aim of our study is to retrospectively evaluate the incidence of premature activation of the hypothalamic-pituitary-gonadal axis, as eviden...

Background/Aims: Since the introduction of Assisted Reproduction Technologies (ART), including classic In Vitro Fertilization (IVF) and Intacytoplasmic Sperm Injection (ICSI), in clinical practice, several studies have addressed concerns regarding the long-term health of the offspring, revealing indications of an adverse cardiometabolic outcome. Proprotein convertase subtilisin/kexin type 9 (PCSK9) circulating level is significantly associated with an increased risk of cardiov...

Background: Obesity in childhood and adolescence represents a major health problem of our century, and accounts for a significant increase in morbidity and mortality in adulthood.Objective and hypotheses: To investigate the effectiveness of a comprehensive and personalized plan of action in the prevention and management of overweight and obesity in childhood and adolescence.Method: 470 children and adolescents (mean age±SEM: 9...

Background: Adenosine deaminase (ADA) deficiency is a systemic metabolic disease that primarily affects the immune system and lymphocyte development, causing a severe combined immunodeficiency (ADA-SCID). However, the accumulation of toxic metabolites occurs in other organs and systems. Since most ADA-SCID patients undergo definitive treatment with Gene Therapy (GT) or allogeneic haematopoietic stem cell transplantation (HSCT), preceded by conditioning (either...

Background: Neonatal hyperparathyrodisim can be caused by homozygous and heterozygous inactivating mutation in the calcium-sensing receptor can cause familial hypocalciuric hypercalcaemia (FHH) or neonatal sever hyperparathyroidism (NSHPTT). NSHPT represents the most sever expression of FHH and courses as life threatening condition.Objective and hypotheses: Neonatal hyperparathyrodisim can be caused by homozygous and heterozygous inactivating mutation in...

Background: The circadian rhythm-generating peripheral Clock/Bmal1 heterodimer complex regulates the circadian activities of many biological systems, including the hypothalamic-pituitary-adrenal (HPA) axis, by trans-activating or trans-repressing downstream target genes.Objective and Hypotheses: To investigate the potential role of elevated cortisol in Clock/Bmal1 heterodimer complex-generated circadian biorhythms, both ...

Background: Neonatal severe hyperparathyroidism (NSHPT) has been associated with inactivating mutations of the calcium-sensing receptor (CASR) gene. Impaired inhibition of PTH secretion by extracellular ionized calcium and decreased urinary excretion of calcium leads to severe hypercalcemia in the first days of life. Calcium responsiveness of the CaSR is amplified by type 2 calcimimetic agents like cinacalcet, which has been able to normalize PTH and calcium levels in cases of...

This prospective population study focuses on metabolic differences between adolescent patients with polycystic ovary syndrome (PCOS) and age/BMI matched non-PCOS controls recruited by the Centre for Adolescent Medicine and UNESCO Chair on Adolescent Health Care of the First Department of Paediatrics, at the ‘Aghia Sophia’ Children’s Hospital, in Athens, Greece. Bioimpendance is an established non-interventional method for the determination of the body compositio...

Background: Signaling through the phosphoinositid-3-kinase (PI3K) pathway modulates bone development and remodeling. We aimed to dissect the role of phosphatase and tensin homolog (Pten), a negative regulator of PI3K signaling, in osteoprogenitor cells.Methods: Femura, tibiae and bone marrow stromal cells (BMSCs) from mice with Cre-inducible Pten knockdown in cells expressing the transcription factor Osterix (Pten cKO) a...

Ulnar-mammary syndrome (UMS) is caused by TBX3 mutation and is a disorder characterized by altered limb, breast, tooth, hair, apocrine gland, and genital development. The detailed genotype-phenotype correlation of TBX3 -related diseases was analysed by the 5.5th UMS case analysis, and all reported cases of UMS were summarized and discussed.Methods: The clinical and genetic data of a boy with UMS were carefully analysed....
