Prenatal exposure to toxic trace elements, including heavy metals, is an important public health concern. Few studies have assessed if individual and multiple elements simultaneously affect cardiac development. The current study evaluated the association between maternal blood lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), selenium (Se) levels congenital heart defects (CHDs) in offspring. This hospital-based case-control included 112 case 107 control infants. Maternal...

Accumulating evidence suggests that environmental pollutants may contribute to the occurrence of congenital heart defects (CHDs). However, no previous studies have evaluated impact perfluoroalkyl substances (PFAS), persistent pollutants, on CHDs. This exploratory study aimed generate testable hypotheses association between gestational PFAS and risk A nested case-control was conducted in a cohort 11,578 newborns. Exposure odds ratios were compared 158 CHD cases non-malformed controls...

Objective: Congenital heart diseases (CHDs) are associated with an extremely heavy global disease burden as the most common category of birth defects. Genetic and environmental factors have been identified risk CHDs previously. However, high volume clinical indicators never considered when predicting CHDs. This study aimed to predict occurrence by considering thousands variables from self-reported questionnaires routinely collected laboratory data using machine learning algorithms. Methods:...

Certain pregnant women suffer from cardiac pathology,and a few of them need operations under cardiopulmonary bypass during pregnancy. Feto-neonatal and maternal outcomes have not been sufficiently described.We conducted retrospective review 22 cases undergoing pregnancy in our hospital Jan.2014 to Mar.2019.All patients were alive after treatment. The types disorders included congenital heart defects, rheumatic disease,infective endocarditis,aortic dissection, obstruction and/or thrombosis...

Importance The association of folate supplementation with congenital heart disease (CHD) prevention is controversial. Objective To examine the maternal serum levels at early to midpregnancy CHD risk in offspring. Design, Setting, and Participants This case-control study recruited participants from one China’s largest cardiac referral centers between 2015 2018. cases non-CHD controls were matched according age a ratio 1:4.

Proximity to greenness has shown protective effects on coronary heart diseases by limiting exposure environmental hazards, encouraging physical activity, and reducing mental stress. However, no studies have previously evaluated the impacts of congenital defects (CHDs). We examined association between maternal residential risks CHDs.We conducted a case-control study (8042 children with major CHDs 6887 controls without malformations) in 21 cities Southern China, 2004 - 2016. cases were...

Abstract Smoke exposure during pregnancy has detrimental effects upon numerous fetal and neonatal outcomes. Nicotine (the main component of tobacco) been suggested to affect placental development. During development, efficient invasion by trophoblasts is required for establishment the fetus–maternal circulation. In this study we explored regulation trophoblast nicotine. An immortalized first trimester extravillous cell line (HTR-8/SVneo cells) was used all experiments, which were treated...
