However, insulin delivery systems with rapid in vivo glucose-respon...

Here, the authors showed that eliminating ERα in kisspeptin arcuate nucleus neurons resulted in high bone mass phenotype in female mice only.<p clas...

To read the full abstract: JAMA Pediatr. 2017;171:1176-1183Adolescence is certainly the most difficult age for reaching T1DM treatment and HbA1c goals. In this age group, most patients have deteriorated metabolic control, and higher risk for acute complications, such as severe hypoglycemia and DKA. Getting into therapeutic contact is very hard in this period of life for diabetes teams ...

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%, ...

In Brief: The study established a novel rat model with a clinically relevant PLS3 mutation, which replicates the osteoporotic phenotype of early-onset PLS3-related osteoporosis. The findings suggest that treatment with alendronate or teriparatide improves bone mass and microarchitecture, suggesting their potential as effective treatments for early-onset osteoporosis caused by PLS3 mutations.Commentary: This study is an essentia...

Brief summary: This ex vivo/ in vitro study describes a novel regulatory mechanism of androgen receptor (AR) gene transcription by intranuclear actin assembly in droplets upon dihydrotestosterone (DHT) stimulation mediated by DAAM2 (Dishevelled-associated activator of morphogenesis 2) gene.Androgen insensitivity syndrome (AIS) is a common etiology in individuals with 46, XY disorder/differences of sex development, AIS has diverse genita...

Brief summary: This study evaluated the ability of genetic risk scores to predict severe obesity in adult survivors of childhood cancer. Data from 2548 survivors of European ancestry from the St. Jude Lifetime Cohort Study was analyzed and findings were validated in 6064 survivors from the Childhood Cancer Survivor Study. Survivors with higher genetic risk scores had significantly higher odds of severe obesity. Adding genetic risk scores to prediction models that included canc...

Brief summary: Two unrelated patients with a disorder of sex development (DSD) phenotype of partial androgen insensitivity (PAIS) showed heterozygous variants in the DAAM2 gene. Their genital skin fibroblasts showed reduced dihydrotestosterone-stimulated androgen receptor (AR) activity. Extensive basic studies revealed the underlying mechanism of the DSD in which DAAM2-regulated actin polymerization at the ligand-inducible androgen receptor is required for androgen-st...

Brief Summary: These authors developed a fully autonomous robotic ultrasound (US) system for thyroid scanning (FARUS). The system consists of a six-degree-of-freedom UR3 manipulator that carries a linear US probe, a US probe fixture, a six-axis force/torque sensor and a Kinect camera. Using reinforcement learning, Bayesian optimization, and deep learning, the system dynamically adjusts the probe position and performs real-time segmentation of thyroid tissue and potential nodul...

Brief Summary:This study tested the discriminatory role of 11-oxygenated androgens to diagnose PCOS in women with obesity, and with ( n =132) or without ( n =83) PCOS. No discriminatory role was found. Instead, insulin resistance, blood pressure, obesity and androgens were the principal components characterizing obese PCOS, while no major characteristic finding defined obese non-PCOS women.Numerous studies have addressed the mechanism o...
