AI Article Synopsis
- The study aimed to evaluate trends in exposure to harmful drugs among pregnant women in France from 2013 to 2019.
- It involved analyzing data from over 5 million pregnancies to determine the prevalence of exposure to teratogenic and fetotoxic drugs during critical pregnancy periods.
- Results indicated that while there was a notable decrease in overall harmful drug exposure during this time, specific drugs such as retinoids and NSAIDs were the most commonly used.
Article Abstract
Objective: Describe the trends of exposure to harmful drugs during pregnancy over recent years in France.
Design: Nationwide cohort study.
Setting: The French National administrative health Data System (SNDS).
Population: Pregnancies starting between 2013 and 2019 and outcomes corresponding to live births, medical terminations of pregnancy, and stillbirths.
Methods: Each pregnancy was divided into a preconceptional period of 90 days before conception and three trimesters from conception to birth. Harmful drugs were defined according to their risks to the fetus: teratogenicity or fetotoxicity. Exposure was defined using the critical period during pregnancy for each type of harmful drug: preconceptional period or first trimester for teratogenic drugs and second or third trimesters for fetotoxic drugs.
Main Outcome Measures: Prevalence of pregnancies exposed to at least one harmful drug.
Results: Among 5,253,284 pregnancies, 204,402 (389 per 10,000) pregnancies were exposed to at least one harmful drug during the critical periods: 48,326 (92 per 10,000) pregnancies were exposed to teratogenic drugs during the preconceptional period or the first trimester, and 155,514 (299 per 10,000) pregnancies were exposed to fetotoxic drugs during the second or third trimesters. Teratogenic drugs were mainly retinoids for topical use (44 per 10,000 pregnancies), antiepileptics (13 per 10,000 pregnancies) and statins (13 per 10,000 pregnancies). Fetotoxic drugs were mainly non-steroidal anti-inflammatory drugs (NSAIDs), for systemic (128 per 10,000 pregnancies) and topical use (122 per 10,000 pregnancies). Exposure to teratogenic drugs decreased from the preconceptional period to the first trimester. Exposure to fetotoxic drugs decreased from the second to the third trimester. Between 2013 and 2019, we found a decrease in harmful drug exposure overall, mainly for topical and systemic NSAIDs and for topical retinoids.
Conclusions: In this nationwide study, about one in 25 pregnancies was exposed to at least one harmful drug, mainly NSAIDs and topical retinoids. Although the prevalence of harmful drug exposure decreased over the study period, NSAID exposure in the second and third trimester remains of concern.

Uterine physiology encompasses the intricate processes governing the structure, function, and regulation of the uterus, a pivotal organ within the female reproductive system. The escalating prevalence of obesity has emerged as a significant global health issue, profoundly impacting various facets of well-being, including female reproductive health. These effects extend to uterine structure and function, influencing reproductive health outcomes in women.

Background: Chromosomal numerical and structural alterations are significant causes of various developmental disorders in foetuses. Non-invasive prenatal testing (NIPT) has emerged as an effective screening tool for detecting common aneuploidies, aiding in the identification of individuals who may require further diagnostic work-up.
Methods: This retrospective, monocentric observational study evaluates the usage patterns, test choices, turnaround times (TAT), and outcomes of NIPT between 2013 and 2023 on a sample of 2431 pregnant women at a special hospital offering outpatient services and comprehensive gynaecological/obstetric inpatient care.

Article Synopsis
- Transient osteoporosis (TO) is a temporary bone condition that commonly occurs in the third trimester of pregnancy, characterized by knee pain in some cases.
- A case study of a 38-year-old pregnant woman showed significant knee pain for 8 weeks, diagnosed as TO, which resolved completely within a few months.
- Healthcare providers should consider TO as a possible diagnosis for knee pain in pregnant women.
Influence of subclinical hypothyroidism and brain-derived neurotropic factor on telomere length dynamics in type 1 diabetic pregnancies and their newborns.

Thyroid dysfunctions are common in type 1 diabetes mellitus (T1DM) pregnancies, impacting embryogenesis and fetal neurodevelopment. This study investigates the effects of subclinical hypothyroidism and BDNF (Brain-derived neurotrophic factor) telomere length in T1DM mothers and their newborns. In a recent study, researchers found an inverse relationship between TSH (thyroid-stimulating hormone) levels and telomere length in the cord blood of newborns.

Background: Gestational diabetes mellitus (GDM) and peripartum depression (PPD) are increasing global health issues with potentially long-lasting adverse outcomes. While limited studies suggest a bidirectional relationship between GDM and PPD, most research has been cross-sectional and focused on one direction of the relationship, primarily if GDM predicts postpartum depression. The interplay between antenatal depression and GDM is less explored, with a critical lack of prospective bidirectional studies.
