Brief Summary: This experimental study unveiled a new link between the β-cell unfolded protein response and senescence. Deletion of the genes Atf6α or Ire1α in β-cells of non-obese diabetic (NOD) mice prior to insulitis generated a p21-driven early senescence phenotype, which altered the β-cell secretome and promoted protective M2 macrophages recruitment to pancreatic islets. M2 macrophages induced immune surveillance and removal of t...

Brief Summary: This study tested a new biosensor, named depth-gated mid-infrared optoacoustic sensor (DIROS), which uses intravital mid-infrared optoacoustic signals, for accurate non-invasive measurement of glucose concentrations in blood-rich volumes of the skin. DIROS provided in-blood glucose measurements with better accuracy and sensitivity than methods that measured glucose in the interstitial fluid.Non-invasive glucose monitoring is an attractive ...

Brief Summary: This study compared 2 groups of adults defined by their leptin concentrations relative to fat mass. Adults with ‘relatively high leptin’ (RHL, n=646) or ‘relatively low leptin’ (RLL, n=644) concentrations were compared in insulin concentration, insulin secretion, and insulin sensitivity, at both the whole-body level and within adipose tissue. Individuals with RHL showed a distinct metabolic phenotype, characterized by insulin resistance in bo...

In Brief: The authors investigated intraperson variability in fasting glucose (FG) levels using continuous glucose monitoring (CGM) devices in 8315 nondiabetic adults aged 40–70 years. Day-to-day intraperson standard deviation of FG was 7.52 mg/dl (0.42 mol/l). This high variability has a large estimated impact on the classification of glycemic status (normal FG, prediabetes or diabetes). Of 5328 adults classified as having normal FG based on their Day 1 measurement, 40% ...

Nature 2021; 592: 80–85https://www.nature.com/articles/s41586-021-03345-1These authors performed whole-genome sequencing (WGS) of 86 bulk placental samples and of 106 microdissections of placental tissue in order to reconstruct the development of human placental cells from data on somatic mutations. They found that the placenta comprises of multiple very large, genetically dis...

Diabetologia, 2021; 64, 375–384.https://link.springer.com/article/10.1007/s00125-020-05302-5#Abs1The authors measured plasma anti-Müllerian hormone (AMH) levels over 2x 5-year intervals in a prospective cohort study of 3293 healthy women aged 20–59 years at baseline. Lower baseline age-specific AMH levels were associated with a higher risk of Type 2 di...

Brief Summary: This study from Israel investigated semen samples from 26 transgender girls aged 14-18 years and notes a general reduction in semen quality parameters. Fertility counselling is mandatory in all transgender adolescents prior to considering hormone interventions, but in ...

PMID: 31769495.Septo-optic dysplasia (SOD) involves a combination of midline brain defects, pituitary hormone deficiency, and optical nerve hypoplasia. The etiology of SOD is multifaceted; genetic factors are known to play a role, yet the vast majority of SOD patients remain withou...

To read the full abstract: Clinical Endocrinology 2020;92:434–442.The authors developed and applied questionnaires to capture various aspects of health-related quality of life (HR-QoL) and psychosocial functioning in a large cohort of adult women with Turner syndrome (TS). Women with TS reported a lower HR-QoL, perceived more stress and experienced increased fatigue compared to the general population. They found a relationship between HR-Qo...
