| 23193214 | This study evaluated the use of fasting plasma glucose (FPG) during the first prenatal visit to diagnose gestational diabetes mellitus (GDM). It found that higher FPG levels at the first visit were strongly correlated with GDM diagnosis later in pregnancy. Women with FPG between 6.10 and 6.99 mmol/L should be treated as GDM, while those with FPG between 5.10 and 6.09 mmol/L should receive nutrition and exercise advice, with a glucose tolerance test (OGTT) performed later to confirm GDM. The study suggests that an FPG value ≥5.10 mmol/L should not be used as the sole criterion for diagnosing GDM. |

| 20175116 | Excessive reactive oxygen species (ROS) production plays a crucial role in the pathogenesis of diabetes and its associated vascular complications. This study investigates whether IH636 grape seed proanthocyanidins (GSPs) can mitigate high glucose (HG)-induced hyperproliferation of vascular smooth muscle cells (VSMCs) and elucidates the underlying molecular mechanisms. The findings demonstrate that GSPs significantly inhibit HG-induced VSMC proliferation, ROS generation, and NADPH oxidase activity. Mechanistically, HG treatment promotes phosphorylation and membrane translocation of Rac1, p47phox, and p67phox subunits, leading to NADPH oxidase activation, a process effectively disrupted by GSPs. Furthermore, GSPs suppress key HG-induced signaling pathways, including ERK1/2, JNK1/2, PI3K/AKT/GSK3β, and NF-κB, which are dependent on ROS generation and Rac1 activation. Notably, PI3K subunit p110α activation is identified as a critical mediator of HG-induced VSMC proliferation and ROS overproduction. Collectively, these findings suggest that GSPs exert vascular protective effects by inhibiting PI3K-dependent pathways, highlighting their potential therapeutic role in preventing intimal hyperplasia and restenosis in diabetic vascular disease. |

| 30877716 | This study assessed biochemical predictors of gestational diabetes mellitus (GDM) and the need for glucose-lowering medication. In 574 pregnant women, those who developed GDM had higher early fasting plasma glucose (FPG), fasting insulin (FI), fasting C-peptide (FCP), and HbA1c levels compared to women with normal glucose tolerance (NGT). Higher FPG and FCP levels were strongly associated with GDM risk. Indices of glucose disposal based on C-peptide, particularly the modified QUICKIc index, showed better predictive accuracy for GDM (ROC-AUC 72.1%) and the need for pharmacotherapy (ROC-AUC 83.7%). Fasting glucose, C-peptide, and glycemic indices can effectively stratify GDM risk early in pregnancy. | Risk factor | GDM |
