Brief Summary: This prospective cohort study of 146 mother-neonate pairs determined fetal-maternal exposure to EDCs from October 2021 – October 2022 and examined their associations with fetal growth parameters. Fetal exposure to bisphenol-A (BPA) showed a linear association with asymmetric fetal growth patterns.Their definition of fetal growth restriction (FGR) when assessed by transabdominal ultrasonography at 38.3 weeks gestational age was a fetal...

Brief Summary: This study used single-cell RNA sequencing to analyze mouse and human thyroid tissue. It discovered two distinct subtypes of thyrocytes, termed thyroid follicular cell (TFC) 1 and TFC2. These subtypes were characterized by varying levels of metabolic activity and Notch signaling: TFC1 cells exhibit higher metabolic activity and Notch signaling compared to the more quiescent TFC2 cells.Notch signaling is a crucial pathway involved in cell f...

Brief Summary: This study investigated the genetic determinants of thyroid function in newborns and (pre)school children by analyzing the associations between single nucleotide polymorphisms (SNPs) previously identified in adults, and childhood TSH within the reference interval, and FT4 concentrations. It included three large population-based cohorts with data on genetic variants and thyroid function: Generation R (Netherlands), ALSPAC (UK), and BLTS (Australia), comprising 7,...

Brief Summary: this case-control study shows that the common genetic variants that influence pubertal timing in the general population also contribute to constitutional delay of puberty (CDP) and less significantly to normosmic idiopathic hypogonadotropic hypogonadism (IHH).CDP and IHH are two different conditions that are notoriously difficult to distinguish clinically on initial presentation. Because CDP has clear heritability traits1, and h...

Brief summary: This study validates dexamethasone-suppressed [11C]metomidate positron emission tomography computed tomography (MTO) scanning as a CYP11B2-selective investigation for lateralizing PA.Primary aldosteronism (PA) is the most common single cause of hypertension, accounting for 5–14% of all cases and 20–25% of treatment-resistant hypertension (1, 2). Traditionally, patients with PA are divided equally into ...

To read the full abstract: J Am Soc Nephrol. 2017 Aug;28(8):2529-2539The association of hyperinsulinaemic hypoglycaemia (HH) and polycystic kidneys has not been reported before. Here, the authors studied 17 patients from 11 different families and found that all patients had a combination HH and polycystic kidneys. The HH was mild and some patients required diazoxide therapy. In contrast the poly...
