Impact of exposure to extreme heat events during pregnancy on the incidence of congenital heart disease in offspring: a meta-analysis.

Background: The aetiology of congenital heart disease (CHD) is multifactorial. Environmental risk factors have emerged as an important modifiable determinant of several congenital cardiac conditions. Previous studies have shown a strong relationship between CHD and air pollution.

Loss of function in protein Z (PROZ) is associated with increased risk of ischemic stroke in the UK Biobank.

Background: The vitamin K-dependent coagulation factor protein Z (PZ), encoded by the PROZ gene, is canonically considered to have anticoagulant effects through negative regulation of factor Xa. Paradoxically, higher circulating PZ concentrations have repeatedly been associated with an elevated risk of acute ischemic stroke.

Objectives: We performed a large-scale genetic association study to examine the relationship between germline genetic variants in PROZ and the risk of ischemic stroke.

AI in ECG: Validating an ambulatory semiology labeller and predictor.

Objectives: Early prediction of epileptic seizures can help reduce morbidity and mortality. In this work, we explore using electrocardiographic (ECG) signal as input to a seizure prediction system and note that the performance can be improved by using selected signal processing techniques.

Methods: We used frequency domain analysis with a deep neural network backend for all our experiments in this work.

Open-heart surgery in preterm infants: A single-center experience.

Background: Open-heart surgery is challenging in preterm neonates and infants, and its feasibility in low-resource settings has not been defined. We describe our institutional experience with open-heart surgeries performed on consecutive preterm infants.

Materials Methods And Results: This was a single-center retrospective cohort from a tertiary hospital in Southern India and included consecutive preterm neonates (<37 weeks) admitted for open-heart surgery.
