To read the full abstract: Endocrinology. 2017 Jul 1;158(7):2102-2112Gestational diabetes mellitus (GDM) produces fetal hyperglycemia with increased lifelong risks for the exposed offspring to cardiovascular and other diseases. In-utero exposure to GDM alters metabolic programming in newborns and their placenta, cord tissues, and cord blood. Human umbilical cord mesenchymal stromal cells (hUC-MSCs...

To read the full abstract: New Engl J Med 2017; 377:1733-1745We are still unable to reach treatment goals in all children and adolescents with T1DM. The usually earliest microvascular complication developed in adolescents and young adults is microalbuminuria. Therefore this trial focused on the prevention of microalbuminuria in high risk adolescents with an albumin-to-creatinine ratio in the uppe...

To read the full abstract: Diabetes Care. 2017;40:920-927Breast feeding has been identified as one albeit weak protective factor protecting from the development of for example obesity, autoimmune disease and in particular T1DM. The mechanisms of this preventive effect are not known. One explanation might still be a confounding effect of social status, overall healthy lifestyles in the families in who...

Brief summary: In this experimental study, immunomodulatory microparticles, consisting of encapsulating self-antigens with rapamycin, were injected into mouse lymph nodes to protect against type 1 diabetes (T1D) and islet graft rejection. Antigens and rapamycin were both required for maximal efficacy and they induced durable tolerance, accompanied by expansion of antigen-specific regulatory T cells (Treg) in both treated and untreated lymph nodes.Antigen...

In Brief: The authors conducted genome sequencing on 151 mother–father–offspring trios from 68 vertebrate animal species in order to estimate and compare germline mutation rates (GMRs). They found a 40-fold variation in GMR per generation between the species. Higher GMRs were observed in species that have a longer generation time, older age at puberty and fewer offspring per generation.Comment: Mutations in germline DNA during gametogenesis are...

The largest reductions were associated with inhaled corticosteroid (ICS) treatment, and these were valida...
