To read the full abstract: Cell Metab. 2019 4;29:1363–1375.Mesenchymal stem and/or stromal cells (MSCs) regulate immune system and have been associated with inflammatory and autoimmune diseases. The IGF system is mainly known for its role in the regulation of growth, development and metabolism. A possible role of IGF-I in inflammation has recently been proposed [1, 2], whereas the e...

To read the full abstract: N Engl J Med. 2019;380(22):2136–2145These authors describe the 5-year follow-up of a multicenter patient cohort of adolescents with severe obesity who underwent gastric bypass surgery to lose weight and improve cardiometabolic risk factors (the Teen-LABS study; n=161, age 13–19 years at time of surgery). They compared these data with a simila...

To read the full abstract: N Engl J Med 2018;378:1987-1998FGF-23 is the primary regulator of phosphate homeostasis and acts by inhibiting phosphate reabsorption in the kidney (1). Loss-of-function mutations in the gene encoding phosphate-regulating endopeptidase homolog X-linked (PHEX) results in excess circulating FGF-23, which impairs renal phosphate reabsorption causing hypophosphatemia...

To read the full abstract: Am J Epidemiol 2017;185:1255-1262Vitamin D and adequate dietary calcium intake are important for skeletal health and therefore it was expected that vitamin D concentration would be associated with increased fracture risk. However, here, the authors did not find any statistically significant association between concurrent 25(OH)D concentration and fracture risk. In addition...

14.1 Estrogen receptor α contributes to T cell–mediated autoimmune inflammation by promoting T cell activation and proliferation

To read the full abstract: Sci. Signal. 2018;11:eaap9415Women are more frequently affected by autoimmune disorders than men. A role for estrogen was suggested by the observation that the development of inflammatory bowel disease was associated with oral contraceptive use. Women also respond to infection and vaccination with higher antibody production and a T helper 2 (TH2) cell&#8211...

1.5. Evaluation of the molecular landscape of pediatric thyroid nodules and use of a multigene genomic classifier in children

Brief summary: In 2021 and 2022, two important publications on pediatric thyroid carcinomas revealed a distinct molecular landscape compared to adult thyroid carcinomas (1,2). Pediatric differentiated thyroid carcinoma was mainly caused by fusion oncogenes, especially in children younger than 10 years (93%), compared to children aged 10–15 years (28%) and 15–20 years old patients (14%). In contrast, PTC due to BRAF mutations showed increasing frequency with age (7%, ...

L Biswas , J Chen , J De Angelis , A Singh , C Owen-Woods , Z Ding , JM Pujol , N Kumar , F Zeng , SK Ramasamy , AP Kusumbe

In Brief: Current dogma is that lymphatic vessels are absent in bone and bone marrow. Using advanced 3D-imaging and mouse genetics, these authors show the presence of lymph vessels in bone. Moreover, they show that genotoxic stress causes lymph vessels expansion and lymphangiogenesis in bone, which in turn promotes bone and hematopoietic regeneration.Commentary: The lymphatic system maintains fluid homeostasis, removes cellular waste products and produce...

Brief summary: This maternal genome-wide meta-analysis of gestational duration (n=195 555) found 22 associated loci and an enrichment in genes expressed during labour. The related meta-analysis of preterm delivery (18 797 cases, 260 246 controls) revealed seven associated loci and large genetic similarities with gestational duration. Maternal alleles that increase gestational duration had a negative effect on birth weight.Preterm delivery is one...

J Clin Endocrinol Metab. 2020 Dec 1;105(12):dgaa633. doi: 10.1210/clinem/dgaa633. PMID: 32898218.In this study, low risk pregnant women had an ‘early’ OGTT at 18-20 weeks of gestation and these results were correlated with the standard OGTT at 24-28 weeks. Pregnant women with Gestational diabetes mellitus (GDM) who had early OGTT still had a higher risk of delivering macrosomic in...
