Diabetes. 2022;71:1591-1596. https://pubmed.ncbi.nlm.nih.gov/35499624/Brief Summary: This cross-sectional study compared trends in plasma C-peptide decline in 4,076 young people with type 1 diabetes (T1D), with trends in beta-cell loss in 235 pancreas donors. As expected, C-peptide declined over time, and this was particularly marked in children with T1D younger than 7 years. Of interest, p...

Brief summary: This paper describes consensus expert recommendations for the diagnosis and management of patients with Adrenoleukodystrophy.Adrenoleukodystrophy (ALD), a progressive metabolic disorder with variable and unpredictable clinical course, is caused by pathogenic variants in ABCD1 gene leading to deficient β-oxidation of saturated very-long-chain fatty acids (VLCFAs) (1, 2). Patients are asymptomatic at birth but ...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...

In Brief: Growth plate and articular cartilage have similar structures composed of distinct chondrocyte layers but they differ substantially with respect to their function and fate. This study combines transplantation experiments with cell tracing in rat with in vitrostudies to identify a novel mechanism by which synoviocytes act directly on chondrocytes to suppress endochondral and promote articular cartilage at the joint surface.Commentary: Gr...

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...
