Objective: We examined the relation of maternal sociodemographic, medical, and behavioral characteristics with risk of abruptio placentae in Peruvian women.
Study Design: This case-control study included 255 abruptio placentae cases and 258 pregnant controls. Multivariable logistic regression models were fit to calculate odds ratios (OR) and 95% CIs adjusted for putative abruptio placentae risk factors.
Results: History of delivering a stillborn infant (OR 10.0; 95%CI 4.0-25.2), pregnancy complicated by preeclampsia/eclampsia (OR 3.7; 95%CI 2.2-6.3); and a low rate of pregnancy weight gain (<0.15 kg/wk) (OR 2.5; 95%CI 1.3-4.7), were associated with significantly increased risk of abruptio placentae. Advanced maternal age, low educational attainment, male infant gender, cigarette smoking, and grand multiparty were not risk factors of abruptio placentae in this population.
Conclusion: At present, the constellation of abruptio placentae risk factors do not provide clinically meaningful opportunities for identifying high-risk patients.

Background: Disseminated intravascular coagulation (DIC) is a potentially fatal condition which is always secondary to an underlying disorder with abruption being the most common cause in obstetrics.Our study analysed the modified International Society of Thrombosis and Haemostasis DIC score for prediction of DIC in cases of abruptio placentae. Additionally, we correlated the score with severity of abruption to optimize its use in limited resource settings.

Maternal exposure to per- and polyfluoroalkyl substances (PFASs) has been linked to adverse pregnancy outcomes (APOs). Nonetheless, the genetic causality underlying this association remains unknown. This research employed a bidirectional two-sample Mendelian randomization (MR) to investigate the potential causal associations between PFASs exposure and APOs risk.

Twins suffer a disproportionately higher burden of adverse perinatal outcomes than singletons. However, the degree to which preterm delivery shapes the relationship between abruption and perinatal mortality in twins is unknown. Through causal mediation decomposition, we examine how preterm delivery mediates the effect of abruption on perinatal mortality among twins using the US-matched multiple birth data (1995-2000).

Article Synopsis
- The study investigates relationships between placental histopathological abnormalities and adverse obstetric outcomes, focusing on conditions like poor blood flow and inflammation.
- Conducted from January 2017 to January 2020, the study analyzed 191 women who experienced adverse outcomes such as preterm labor (25.1%) and fetal growth restriction (19.4%).
- Findings revealed that 74% of women had abnormal placental results, with specific lesions correlating to conditions like preterm labor and preeclampsia, highlighting the necessity of histopathological exams for better management in future pregnancies.
