Background Per- and poly-fluoroalkyl substances (PFAS) can influence gestational diabetes mellitus (GDM); however, current studies on their association are limited and have yielded inconsistent findings. Objective To investigate the association between maternal exposure to PFAS, as measured by urinary concentrations in early pregnancy, and the risk of developing GDM. Methods Based on the Wuhu Birth Cohort in Anhui Province conducted between 2020 and 2023, this study included 1910 pregnant women. Urine samples were collected during the first trimester, and a 75 g oral glucose tolerance test (OGTT) was completed at 24–28 gestational weeks. The concentrations of six PFAS in urine were measured using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Participants were categorized into low, medium, and high exposure groups according to tertiles of individual PFAS concentrations. Logistic regression analysis was employed to assess the potential impact of early-pregnancy PFAS exposure levels on the risk of GDM, with stratified analyses by maternal age and fetal sex. A generalized weighted quantile sum regression (gWQS) model was applied to evaluate the relative weight distribution of the six PFAS in their mixture effect. Results The logistic regression results revealed that both medium exposure to perfluorohexane sulfonate (PFHxS) (OR=1.475, 95%CI: 1.040, 2.093) and high exposure to perfluorononanoic acid (PFNA) (OR=1.430, 95%CI: 1.013, 2.018) were positively associated with diagnosed GDM. This association was more pronounced among women older than 28 years. Among pregnant women carrying male fetuses, high-level exposures to per fluorohexanoic acid (PFHxA) (OR=1.708, 95%CI: 1.006, 2.899) and PFHxS (OR=2.116, 95%CI: 1.247, 3.584) showed positive associations with diagnosed GDM. In contrast, among those carrying female fetuses, moderate perfluorooctanesulfonic acid (PFOS) exposure was associated with a lower risk of GDM (OR=0.542, 95%CI: 0.311, 0.946). The gWQS results demonstrated that PFOS (0.48) and perfluorobutane sulfonate (PFBS) (0.34) contributed the most to the mixture effect. Conclusion Early-pregnancy exposure to PFAS (particularly PFHxS and PFNA) may be an etiological factor for GDM, with maternal age and fetal sex potentially acting as effect modifiers in this association.

With the integration of 5G communication technology and robotic surgical systems, remote robot-assisted thoracic surgery is overcoming geographical barriers, offering an innovative approach to addressing the uneven distribution of medical resources. This study conducted a systematic literature review—using databases such as PubMed and CNKI, with the search period extending up to 2025—incorporating clinical studies, case reports, and review articles to comprehensively evaluate the clinical efficacy and safety of 5G-enabled remote robot-assisted thoracic surgery (5G-RRATS). The analysis also examined current technological limitations and potential future development trajectories. Existing evidence indicates that, given adequate technical support, 5G-RRATS can achieve perioperative outcomes comparable to those of conventional local robotic surgeries across procedures including pulmonary wedge resection, lobectomy, and esophagectomy. Furthermore, it demonstrates potential advantages in minimizing surgical incisions and reducing intraoperative blood loss. Nevertheless, challenges related to network stability, latency control, interdisciplinary collaboration between medical and engineering teams, and legal, regulatory, and ethical considerations continue to hinder widespread clinical adoption. Looking ahead, the emergence of a "one-to-many" remote surgical model, combined with the integration of artificial intelligence and augmented reality technologies, as well as advancements in low-orbit satellite communications, may enable 5G-RRATS to further advance precision and efficiency in thoracic surgery, thereby facilitating equitable access to high-quality care for a broader patient population.

Objective:Investigate the clinical characteristics of patients with coronary artery disease (CAD) and moderate-to-severe coronary calcification lesions confirmed by intravascular ultrasound (IVUS), and to compare the prevalence of moderate-to-severe calcification lesions among different clusters of patients with CAD.Methods:This cross-sectional study enrolled patients with coronary artery disease who underwent coronary angiography and IVUS at the General Hospital of Northern Theater Command from June 2016 to June 2023. Patients with mild calcification were excluded, and the remaining cohort was divided into moderate-to-severe calcification and non-calcification groups. The least absolute and selective operator logistic regression was used to identify baseline variables associated with mederate-to-severe calcification. Hierarchical cluster analysis was used to identify similarities in clinical baseline data among patients, and the prevalence of moderate-to-severe coronary calcification was compared across different clusters of patients with CAD.Results:A total of 1 406 patients with CAD were enrolled (age (60.7±10.0) years; 963 males (68.5%)). A total of 563 patients were assigned in the moderate-to-severe calcification group and 843 patients were assigned in the non-calcification group. The least absolute and selective operator logistic regression identified 23 baseline variables associated with moderate-to-severe coronary artery calcification. Hierarchical cluster analysis based on these 23 variables divided all patients into Cluster 1 (500 cases) and Cluster 2 (906 cases). Patients in Cluster 1 were characterized by high age, high body mass index, high diastolic blood pressure, elevated mean arterial pressure, history of hypertension, history of diabetes, low endogenous creatinine clearance, high fasting blood glucose, low high-density lipoprotein cholesterol (HDL-C), high lipoprotein(a), high alkaline phosphatase, high glycated hemoglobin, low serum albumin, high triglycerides/HDL-C ratio, high HbA1c/HDL-C ratio, and high triglyceride glucose index. Cluster 1 (49.6%, 248/500) exhibited a significantly higher prevalence of moderate-to-severe coronary artery calcification compared to Cluster 2 (34.8%, 315/906, P=0.002). Conclusions:Patients with moderate-to-severe coronary artery calcification exhibited clinical heterogeneity compared to those without calcification. A subgroup characterized by high age, elevated body mass index, high diastolic blood pressure, elevated mean arterial pressure, history of hypertension, history of diabetes, low endogenous creatinine clearance, and high fasting blood glucose levels demonstrated a higher prevalence of moderate-to-severe coronary artery calcification.
