Brief summary: This paper describes 18 patients with bi-allelic leptin deficiency (LEP, n=11) or leptin receptor deficiency (LEPR, n=7), including 10 new cases and two novel variants. In addition, in a review of the literature (until July 2022), the authors identified n=75 patients living with LEP deficiency and n=90 with LEPR deficiency (n=152 included for comparison between groups).<p class=...

To read the full abstract: Lancet Diabetes and Endocrinology 2018; 6: 114–121Cystic fibrosis (CF)-related diabetes (CFRD) impacts significantly on mortality and quality of life. Impaired glucose metabolism and CFRD are associated with poor weight and height gain and impaired lung function in children and adolescents (1). In that study, height and weight were lower in CF patients wit...

To read the full abstract: Pediatr Diabetes. 2018;19:749–755.Disordered eating behaviors (DEBs) may lead to full blown eating disorders and these might impair patients’ adherence to chronic disease management. Both type 1 diabetes mellitus (T1DM) and celiac disease (CD) are associated with DEBs. Adolescents with T1D and eating disorders have worse metabolic control and a higher...

Brief summary: In recent years, generation of human organoids of different tissues from human embryonic stem cells have been realized, e.g. intestine, liver, and lung among others. In contrast, so far all attempts to generate fully mature and functional human thyroid follicular cells from stem cells was not successful. Romitti et al. present for the first time successful generation of transplantable and functional human thyroid organoids derived from human embryonic s...
