Brief summary: Steroid analysis using LC-MS/MS in association with clinical parameters may be used to develop a diagnostic score that could successfully differentiate premature pubarche (PP) from non-classic congenital adrenal hyperplasia (NCCAH), thereby obviating the need for ACTH stimulation testing.Late onset, non-classic congenital adrenal hyperplasia (NCCAH) due to 21-hydroxylase deficiency (21-OHD) should be ruled out in children with premature pu...

Brief summary: This single-centre retrospective study analysed gonadal function in 62 patients (41 males) with medulloblastoma, treated between 1987 and 2021. The aim of the study was to characterize gonadal function and identify risk factors for gonadal failure.Survival rates of patients with medulloblastoma have significantly improved with the combination of many therapeutic approaches, such as adjuvant chemotherapy, craniospinal irradiation (CSI), sur...

Brief summary: The authors used data from the Global Burden of Disease 2019 to examine the incidence, disability adjusted life years and mortality of early onset type 2 diabetes T2D) in those 15–39 years of age. This showed that early onset T2D is a growing global health problem in adolescents and young adults, particularly in low-middle- and middle-income countries.Early onset of type 2 diabetes (T2D) is associated with longer lifetime exposure hyp...

Circulation, 2022: Jun 21;145(25):1853-1866 PMID: 35616058Brief Summary: This translational study evaluated cardiac health and lifespan in two cardiomyocyte-specific transgenic mice with either enhanced or reduced IGF-1 signaling and in human cardiac biopsies from failing and nonfailing hearts. Increased IGF1R expression was related to better cardiac performance in young mice but faster decline of cardiac function with aging. Conversely reduced ...
