Background: Prader–Willi Syndrome (PWS) is a complex genetic disease; one hallmark of the disease is failure to regulate hunger and metabolism. Hyperphagia and severe obesity contribute significantly to the morbidity and mortality of this disease. Methionine aminopeptidase 2 (MetAP2) inhibition reduces fat biosynthesis and stimulates fat oxidation and lipolysis. Beloranib is a selective and potent MetAP2 inhibitor. In a 4-week phase 2, placebo-controlled, proof-of-concept...

Background: Kisspeptin (encoded by the KISS1 gene in humans), originally described as a puberty onset regulating neuropeptide, is involved in many homeostatic systems, including nutrition status, glucose homeostasis, locomotor activity, etc. Thus, in today’s obesity epidemic, kisspeptin is gaining increasing interest as a research target.Aim: To construct an updated interactome of genetic determinants of obesity, including the kisspeptin si...

Background: Translational research has provided evidence of autonomic nervous system (ANS) interactions with cytokines and gut hormones. In the gastrointestinal track, the crosstalk of the stimulated vagus nerve with immune cells enhances the cholinergic tone. In obesity, on the other hand, hyperinsulinemia and hyperleptinemia induce ANS activation.Aim: To synthesize literature results exploring links among the autonomic nervous system, gut hormones, imm...

Aim: This study aims to screen the genes/gene products associated with the polycystic ovary syndrome (PCOS) and to predict any possible interactions among them with high confidence. These interactions networks could contribute to the better understanding of PCOS pathophysiology and help generate new hypothesesMethods: Systems medicine approach using STRING v10.5 database and confidence level 0.7, interactions networking.Results: We...

Background: OPKO Biologics is developing MOD-4023, a long-acting growth hormone (GH), intended for weekly dosing for the treatment of idiopathic GH deficiency in children. At ESPE2015, we presented pharmacokinetic (PK) and pharmacodynamic (PD, based on IGF-1) models for weekly MOD-4023 administration in children aged 3–11 years. These models confirm that IGF-1 (and IGF-1 SDS) varies during the dosing interval. One critical clinical and research issue is when to optimally ...

Background: The hypothalamic–pituitary–adrenal (HPA) axis responds to several acute or chronic environmental stessors, including those of social stress.Objective and hypotheses: To assess the HPA axis acute response during mental stress and mobile phone call exposure in healthy adolescents through salivary cortisol measurements and to investigate the modulatory effect of baseline biochemical or low-inflammation markers during this response....

Background: OPKO Biologics is developing MOD-4023, a long-acting growth hormone (GH), intended for weekly dosing for the treatment of idiopathic GH deficiency in children. At ESPE2015, we presented pharmacokinetic (PK) and pharmacodynamic (PD, based on IGF-1) models for weekly MOD-4023 administration in children aged 3–11 years. Those models were based on data collected during the ‘PKPD period’ (the second steady state dose of MOD-4023) and monthly values during...

Background, objective, and hypotheses: OPKO Biologics has produced a long-acting human GH (hGH), MOD-4023, containing copies of a naturally-occurring C-terminal peptide (CTP) to markedly increase GH’s in vivo residence. We describe the construction and validation of a pharmacokinetic (PK)/pharmacodynamics (PD) model to characterise the relationship between MOD-4023 dose, MOD-4023 serum concentrations (Cserum), and IGF1 responses in healthy adults, GH-deficient (G...

In this case-control study 19 Greek adolescents with Polycystic Ovary Syndrome (PCOS) and 21 non-PCOS controls were assessed for their hormonal, somatometric and autonomic nervous system profile in supine position. The study adhered to the Helsinki Guidelines of Good Clinical Practice. Significant differences were found only in very low frequencies (VLF) (P = 0.008) and Power spectral density RR (PSD) (P < 0.001) between adolescents with PCOS and controls...

Background: The prevalence of childhood type 1 diabetes mellitus (T1DM) is increasing and the age at presentation is falling. Late presentation with diabetic ketoacidosis (DKA) is more common in younger children who are at increased risk of cerebral oedema.Objective and hypotheses: To describe the clinical presentation of new onset T1DM to our centre and report time to diagnosis, incidence of DKA, requirement for intensive care and complications.<p c...
