Background: This meta-analysis was performed to examine the association between maternal hypertension during pregnancy (HDP) and neonatal bronchopulmonary dysplasia (BPD).
Methods: We systematically searched PubMed, EMBASE, the Cochrane Library, and the KoreaMed database for relevant studies. We used the Newcastle-Ottawa Scale for quality assessment of all included studies. The meta-analysis was performed using Comprehensive Meta-Analysis software (version 3.3).
Results: We included 35 studies that fulfilled the inclusion criteria; the total number of infants evaluated came to 97,399 through review process. Maternal HDP was not significantly associated with any definition of BPD, i.e., oxygen dependency at 36 weeks of gestation (odds ratio [OR], 1.162; 95% confidence interval [CI], 0.991-1.362; = 0.064) in pooled analysis of 29 studies or oxygen dependency at 28 days of age (OR, 1.084; 95% CI, 0.660-1.780; = 0.751) in pooled analysis of 8 studies. Maternal HDP was significantly associated only with severe BPD (OR, 2.341; 95% CI, 1.726-3.174; < 0.001). BPD was not associated with HDP in the overall analysis (OR, 1.131; 95% CI, 0.977-1.309; = 0.100) or subgroup analysis according to the definition of HDP.
Conclusion: Maternal HDP was not associated with neonatal BPD defined by the duration of oxygen dependency (at either 36 weeks of gestation or 28 days of life) but was associated with severe BPD.

Aims: Studies evaluating the relationship between adverse pregnancy outcomes (APOs), namely hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM), with the estimated risk of atherosclerotic cardiovascular disease (ASCVD) remains limited and could inform patient-centred decision-making in the postpartum period. We examined whether HDP or GDM were associated with a higher 10- and 30-year predicted risk of ASCVD measured 10-14 years after delivery.
Methods: A secondary analysis from the international prospective Hyperglycemia and Adverse Pregnancy Outcome Follow-up Study (2013-2016) cohort.

Background: sFLT-1 has been implicated in the pathogenesis of HDP. We aimed to examine the role of maternal and fetal polymorphisms in risk of HDP and severe-spectrum disease.
Methods: Cases of HDP (143) and controls (169) from mother-baby dyads were recruited at the Los Angeles County Women's and Children's Hospital (WCH).

Background: Maternal obesity is associated with maternal complications, including hypertensive disorders of pregnancy (HDP), and related fetal complications, such as fetal growth restriction. During pregnancy, the placenta is one of the key regulators of embryonic and fetal growth. Previous studies mainly investigated placental growth by measuring postpartum placental weight.

Background: Maternal hypertensive disorders of pregnancy (HDP) was associated with increased risk of congenital hypothyroidism in preterm infants, but its underlying mechanisms remain unclear.
Objective: To investigate the possible mechanisms by which intrauterine exposure to HDP affects thyroid hormone synthesis in preterm infant rats.
Methods: preterm infant rats were obtained by Caesarean section delivery from the L-NAME group and Control groups which was induced by L-NAME and saline, respectively.

Background: Aspirin has proved its efficacy in reducing the rate of preeclampsia in singleton pregnancy, however, there is discrepancy about the efficient dosage that should be used. While some societies recommend daily 75-81mg, others recommend higher dosage (160mg). This discrepancy is due to the lack of randomized controlled studies that compare these two dosages.
