The Iodine Status in Pregnancy and Offspring Health Cohort (ISPOHC) was initiated in Shanghai to address the need for a comprehensive and longitudinal study on iodine nutrition and its effects on maternal and offspring health. The findings based on the Shanghai population can serve as a reference for other megacities experiencing significant dietary changes simultaneously. ISPOHC utilized a stratified cluster random sampling design, enrolling 5,099 pregnant women from all 16 districts of Shanghai. The survey has been conducted in three phases. Data collected at different time points include health status, living habits, dietary intake, birth, feeding, early development, anthropometric measurements, and biomarkers, allowing for an in-depth evaluation of iodine nutrition's impact on offspring development. Data were collected through a combination of questionnaires, home visits, anthropometric measurements, and biological sample collection. The integration of detailed food investigation and on-site weighing of household seasonings provides a more precise assessment of dietary iodine intake, particularly iodized salt consumption, distinguishing this study. The study has provided significant insights into the relationship between iodine nutrition during pregnancy and various health outcomes.

Non-obstructive azoospermia (NOA), characterized by impaired spermatogenesis and the complete absence of sperm in the ejaculate, represents one of the most severe forms of male infertility. Current diagnostic strategies rely on invasive procedures such as testicular sperm extraction, underscoring the urgent need for reliable, non-invasive alternatives. In the present study, we performed untargeted metabolomic profiling of human seminal plasma to identify biomarker panels capable of stratifying azoospermia subtypes through a stepwise approach.

Purpose: To determine if melatonin-enriched culture media could offset loss of imprinting in mouse concepti.
Methods: Zygotes were cultured to blastocyst stage under optimized conditions in melatonin-supplemented media at either 10 M (MT 10) or 10 M (MT 10), or without supplementation (Culture + embryo transfer, or ET, positive control). Blastocysts were also developed in vivo (ET negative control).

Microplastic particulates (MPs) accumulate widely in ecosystems and pose health risks to both pregnant women and their offspring. Studies have detected MPs in the kidneys and fetal tissues, but it remains unclear whether maternal MP exposure worsens postnatal MP-induced hypertension and kidney disease. This study examined male rat offspring (n = 8/group) divided into four exposure groups: control, indirect (maternal exposure to 1 mg/L MPs during gestation and lactation), direct (offspring exposure to 1 mg/L MPs from 3 to 16 weeks), and combined exposure.

Background: The detrimental health effects of adverse childhood experiences (ACEs) are well documented, yet their impact on metabolic multimorbidity remains unclear. This study aimed to examine the associations of ACEs with adult metabolic disease and multimorbidity, and to assess whether adopting a healthy lifestyle in adulthood could mitigate these risks.
Methods: We analyzed 70,438 participants without any metabolic disease at enrolment in the UK Biobank.
