AI Article Synopsis
- The study aimed to assess changes in the incidence of neural tube defects (NTDs) in Shaanxi province from 2003 to 2022, analyze diagnosis timing and outcomes of affected infants, and predict future incidences for 2023-2025 to enhance the birth defects surveillance system.
- During the survey period, 1,106,483 perinatal infants were analyzed, revealing an overall NTD incidence of 7.66 per 10,000, with the highest rate in 2005 (48.02/10,000) and a significant decline to 0.57/10,000 by 2022, largely due to improved prenatal diagnosis.

Article Abstract
Objective To evaluate the changes in the incidence of neural tube defects (NTDs) in Shaanxi province from 2003 to 2022,investigate the diagnosis time and outcomes of defective infants,and predict the incidence of NTDs in Shaanxi province from 2023 to 2025,thereby providing a basis for improving the birth defects surveillance system. Methods Data were collected from all the perinatal infants from 28 weeks of gestation to 7 days after birth in all the hospitals with obstetrical department in Shaanxi province during 2003-2022.The changes in the incidence of NTDs from 2003 to 2022 were analyzed based on the birth defects surveillance system. Results A total of 1 106 483 perinatal infants in Shaanxi province from 2003 to 2022 were surveyed,among which NTDs occurred in 848 perinatal infants,with an incidence of 7.66/10 000.The incidence was the highest (48.02/10 000) in 2005 and the lowest (0.57/10 000) in 2022.The NTDs in Shaanxi province were mainly spina bifida (55.90%),which was followed by anencephaly (25.71%) and encephalocele (18.40%).The incidences of the three declined with fluctuations (<0.001).The results of the Joinpoint analysis showed that the incidence of NTDs decreased slowly with the annual percentage change of -4.04 from 2003 to 2014 and declined rapidly with the annual percentage change of -28.05 from 2014 to 2022.From 2003 to 2022,the average proportion of prenatal diagnosis of NTDs in Shaanxi province was 72.88%.Dead fetus (61.91%) was the main birth outcome,followed by live birth (26.77%),stillbirth (8.73%),and death within seven days after birth (2.59%).The incidence of NTDs in Shaanxi province from 2023 to 2025 were predicted by the GM (1,1) model as 0.49/10 000,0.41/10 000,and 0.35/10 000,respectively. Conclusion The incidence of NTDs in Shaanxi province declined significantly during 2003-2022,especially in a rapid manner after 2014.Dead fetus was the primary outcome of perinatal infants with NTDs,followed by live birth.

Acute liver failure (ALF) is marked by a substantial generation of reactive oxygen species (ROS), which can induce both cellular senescence and a pronounced inflammatory response. Senescent cells secrete factors collectively termed the senescence-associated secretory phenotype (SASP), which exacerbate inflammation, while inflammation can reciprocally promote cellular senescence. Quercetin (Que), recognized for its ROS-scavenging capabilities, holds the potential for anti-inflammatory and anti-senescent effects.

Methylene blue (MB) contamination has become a significant environmental issue due to its widespread presence in industrial effluents, posing serious threats to ecosystems and human health. As a result, there is an urgent need for the development of novel adsorbent materials that can effectively remove these pollutants from water sources. In this context, the present study focuses on the design and synthesis of two coordination polymers (CPs) containing Zn(II) and Mn(II), namely, {[Mn(L)(tib)]·4HO} (1) and [Zn(L)(3,5-bibp)] (2), using a combined-ligand approach under solvothermal conditions.

(AlO)(HfO) films with varying compositions were deposited on silicon substrates via plasma-enhanced atomic layer deposition (PEALD), and metal-oxide-semiconductor (MOS) capacitors were fabricated. The impact of varying induced Al content on the dielectric properties of HfO was examined through electrical measurements. The results showed that increasing Al content raised the flat-band voltage, reduced the interface state density (D), and significantly lowered the leakage current at a given voltage.

Background: Osteoarthritis (OA) is a common degenerative joint disease that significantly impacts the quality of life, especially among older adults. Testosterone, a critical hormone for musculoskeletal health, has been suggested to influence OA pathogenesis. However, the relationship between low testosterone levels and OA risk remains underexplored in large, representative populations.
