Abstract
BACKGROUND Premature rupture of membranes (PROM) is a complication affecting 7-12% of pregnancies in which fetal chorioamniotic membranes rupture before labour begins. Preterm PROM (PPROM) (ie <37 weeks gestation) precedes one-third of preterm births, exposing the fetus to increased morbidity from placental abruption, respiratory distress syndrome and sepsis. AIM To analyse trends in the incidence and mode of birth in preterm and term PROM in Victoria, Australia between 2009 and 2017. MATERIALS AND METHODS This retrospective population-based cohort study included all singleton pregnancies from 2009 to 2017. We examined women with PROM (both <37 weeks (PPROM) and at term). Management was assessed in three categories: (a) expectant management; (b) induction of labour (IOL); and (c) elective caesarean section (elCS). A multinomial logistic regression model was used to adjust for confounders influencing the choice of management. RESULTS Of 636 590 singleton pregnancies, 52 669 (8.3%) births with PROM at term (42 439; 6.7%) or PPROM (10 230; 1.6%) were identified. Of these, the majority were managed expectantly (n = 22 726; 43.1%), or with IOL (25 931; 49.2%). While elCS represented only 7.6% of these cases (n = 4012), its use rose consistently from 2009 to 2017 for PROM at term and PPROM alike. For women with PPROM at 34-36 weeks the odds of elCS increased by 5% annually (adjusted odds ratio (aOR) 1.05; 95% CI 1.02-1.08) and 2% for IOL (aOR 1.02; 95% CI 1.00-1.05) vs expectant management. CONCLUSIONS The use of elCS and IOL in PPROM is rising in Victoria, particularly between 34 and 36 completed weeks of pregnancy. Research is needed to determine the drivers for this increase.

Abstract
OBJECTIVE Risk factors of early- and late-onset preeclampsia among pregnant individuals with chronic hypertension are not well described in the literature. We hypothesized that early- and late-onset superimposed preeclampsia (SIPE) have different risk factors. Therefore, we aimed to examine the risk factors of early- and late-onset SIPE among individuals with chronic hypertension. STUDY DESIGN This was a retrospective case-control study of pregnant individuals with chronic hypertension who delivered at 22 weeks' gestation or greater at an academic institution. Early-onset SIPE was defined as SIPE diagnosed before 34 weeks' gestation. To identify risk factors, we compared individuals' characteristics between individuals who developed early- and late-onset SIPE and those who did not. We then compared characteristics between individuals who developed early-onset SIPE and late-onset SIPE. Characteristics with p-values of less than 0.05 by bivariable variables were analyzed by simple and multivariable logistic regression models to calculate crude and adjusted odds ratios (aOR) and 95% confidence intervals (95% CI). Missing values were imputed with multiple imputation. RESULTS Of 839 individuals, 156 (18.6%) had early-onset, 154 (18.4%) had late-onset SIPE and 529 (63.1%) did not have SIPE. The multivariate logistic regression model showed that serum creatinine ≥ 0.7 mg/dL compared to less than 0.7 mg/dL (aOR: 2.89 [95% CI: 1.63-5.13]), increase of creatinine (1.33 [1.16-1.53]), nulliparity compared to multiparity (1.77 [1.21-2.60]), and pregestational diabetes (1.70 [1.11-2.62]) were risk factors for early-onset SIPE. The multivariate logistic regression model showed that nulliparity compared to multiparity (1.53 [1.05-2.22]) and pregestational diabetes (1.74 [1.14-2.64]) was a risk factor for late-onset SIPE. Serum creatinine ≥ 0.7 mg/dL (2.90 [1.36-6.15]) and increase of creatinine (1.33 [1.10-1.60]) were significantly associated with early-onset SIPE compared to late-onset SIPE. CONCLUSION Kidney dysfunction seemed to be associated with the pathophysiology of early-onset SIPE. Nulliparity and pregestational diabetes were common risk factors for both early- and late-onset SIPE. KEY POINTS · Serum creatinine level was positively associated with early-onset superimposed preeclampsia (SIPE).. · Pregestational diabetes and nulliparity were associated with both early- and late-onset SIPE.. · The identification of risk factors may provide an opportunity to decrease the rates of SIPE..

Abstract
OBJECTIVE Superimposed preeclampsia (SIPE), defined as preeclampsia in individuals with chronic hypertension, is one of the most common complications, accounting for 13 to 40% of pregnancies with chronic hypertension. However, there are limited data regarding maternal outcomes of early- and late-onset SIPE in individuals with chronic hypertension. We hypothesized that early-onset SIPE was associated with increased odds of adverse maternal outcomes compared with late-onset SIPE. Therefore, we aimed to compare adverse maternal outcomes between individuals with early-onset SIPE and those with late-onset SIPE. STUDY DESIGN This was a retrospective cohort study of pregnant individuals with SIPE who delivered at 22 weeks' gestation or greater at an academic institution. Early-onset SIPE was defined as the onset of SIPE before 34 weeks' gestation. Late-onset SIPE was defined as the onset of SIPE at or after 34 weeks' gestation. Our primary outcome was a composite of eclampsia, hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome, maternal death, placental abruption, pulmonary edema, SIPE with severe features, and thromboembolic disease. Maternal outcomes were compared between early- and late-onset SIPE. We used simple and multivariate logistic regression models to calculate crude and adjusted odds ratios (aOR) with 95% confidence intervals (95% CI). RESULTS Of 311 individuals, 157 (50.5%) had early-onset SIPE, 154 (49.5%) had late-onset SIPE. There were significant differences in the proportions of obstetric complications, including the primary outcome, HELLP syndrome, SIPE with severe features, fetal growth restriction (FGR), and cesarean delivery between early- and late-onset SIPE. Compared with individuals with late-onset SIPE, those with early-onset SIPE had increased odds of the primary outcome (aOR: 3.28; 95% CI: 1.42-7.59), SIPE with severe features (aOR: 2.72; 95% CI: 1.25-5.90), FGR (aOR: 6.07; 95% CI: 3.25-11.36), and cesarean delivery (aOR 3.42; 95% CI: 2.03-5.75). CONCLUSION Individuals with early-onset SIPE had higher odds of adverse maternal outcomes compared with those with late-onset SIPE. KEY POINTS · We revealed the incidence of maternal outcomes in early- and late-onset SIPE.. · Severe features were common in individuals with SIPE.. · Early-onset SIPE was associated with increased adverse maternal outcomes compared with late-onset SIPE..

Abstract
OBJECTIVES To analyze the hypertensive disorders of pregnancy (HDP) trends in the 2000-2020 period and its association with social determinants of health (SDH) in Mexican municipalities. STUDY DESIGN This was a retrospective longitudinal study analyzing data from routine information systems on 21,493,076 hospital discharges due to maternal causes and SDH data of 2,439-2,450 municipalities between 2000 and 2020. MAIN OUTCOMES MEASURES We used joinpoint regression models to analyze HDP trends and hybrid negative binomial regression models to examine the association between SDH and HDP rates at intra- and inter-municipality levels. RESULTS HDP rate increased from 0.54 in 2000 to 2.42 cases per 100 live births in 2020 (annual average percent change of 7.7 %, 95 % CI 6.6-8.9). Municipalities with higher marginalization index had higher HDP rates (IRR 1.12, 95 % CI 1.01-1.24; 1.36, 95 % CI 1.25-1.47; 1.30, 95 % CI 1.23-1.37, and 1.06, 95 % CI 1.00-1.12, in 2000-2004, 2005-2009, 2010-2014, 2015-2020, respectively). Municipal increases in the percentage of population with high schooling were associated with decreases in HDP rates in 2000-2009. Meanwhile, the role of socioeconomic status at the state level was less consistent, yet the HDP rates were lower in most socially advantaged regions. CONCLUSION During 21 years, HDP rates increased overall in Mexican municipalities, suggesting an increased maternal morbidity burden due to HDP. The association of municipal marginalization and socioeconomic level with HDP trends indicates a need to ensure equitable interventions to improve maternal health in Mexican municipalities.

Abstract
OBJECTIVES To evaluate the prevalence and perinatal repercussions of preeclampsia (PE) after the implementation of a prophylaxis protocol with aspirin in singleton pregnancy at Maternity School of Federal University of Rio de Janeiro, Rio de Janeiro, Brazil (2015-2106). METHODOLOGY PE prevalence according to gestational age (GA) and the prevalence ratio (PR) between PE and prematurity, small for gestational age (SGA), and fetal death were calculated in patients assisted during 2015 and 2016. RESULTS PE occurred in 373(10.75%) of 3468 investigated cases, where PE < 37 weeks was of 2.79% and PE greater than 37 weeks was of 7.95%. A total of 413 (11.9%) prematurity cases, 320 SGA (9.22%), and 50 fetal deaths (1.44%) occurred. In the PE group, 97 premature newborns (PR 0.90) and 51 SGA (PR 1.16) were born, and two fetal deaths occurred (PR 7.46). Concerning PE < 37 weeks, 27 SGA cases (PR 1.42) and two fetal deaths (PR 2.62) were observed. Regarding PE greater than 37 weeks, 24 SGA (PR 1.09) were born, and no fetal deaths were observed. Our findings were compared to previously published results. CONCLUSIONS PE was significantly associated with SGA newborns, especially premature PE. Prescribing aspirin for PE prophylaxis based only on clinical risk factors in a real-life scenario does not appear to be effective but resulted in a PE screening and prophylaxis protocol review and update at ME/UFRJ.

Abstract
OBJECTIVE The objective of this study was to determine adverse maternal and perinatal outcomes in pregnant women with hypertensive disorders of pregnancy. METHODS An analytical cross-sectional study was conducted on women admitted with hypertensive disorders of pregnancies to a university maternity hospital from August 2020 to August 2022. Data were collected using a pretested structured questionnaire. Variables associated with adverse maternal and perinatal outcomes were compared using multivariable binomial regression. RESULTS Of 501 women with pregnancies, 2, 35, 14, and 49% had eclampsia, preeclampsia, chronic hypertension, and gestational hypertension, respectively. Women with preeclampsia/eclampsia had significantly higher risks of cesarean section (79.4 vs. 65%; adjusted RR, 2,139; 95%CI, 1,386-3,302; p=0.001) and preterm delivery at <34 weeks' gestation (20.5 vs. 6%; adjusted RR, 2.5; 95%CI, 1.19-5.25; p=0.01) than those of women with chronic/gestational hypertension. Risks of prolonged maternal hospitalization (43.9 vs. 27.1%), neonatal intensive care unit admission (30.7 vs. 19.8%), and perinatal mortality (23.5 vs. 11.2%) were higher among women with preeclampsia/eclampsia. CONCLUSIONS Women with preeclampsia/eclampsia had a higher risk of adverse maternal and neonatal outcomes than those with chronic or gestational hypertension. This major maternity care center requires strategies for preventing and managing preeclampsia/eclampsia to improve pregnancy outcomes.

Abstract
Pre-eclampsia is a life-threatening disease of pregnancy unique to humans and a leading cause of maternal and neonatal morbidity and mortality. Women who survive pre-eclampsia have reduced life expectancy, with increased risks of stroke, cardiovascular disease and diabetes, while babies from a pre-eclamptic pregnancy have increased risks of preterm birth, perinatal death and neurodevelopmental disability and cardiovascular and metabolic disease later in life. Pre-eclampsia is a complex multisystem disease, diagnosed by sudden-onset hypertension (>20 weeks of gestation) and at least one other associated complication, including proteinuria, maternal organ dysfunction or uteroplacental dysfunction. Pre-eclampsia is found only when a placenta is or was recently present and is classified as preterm (delivery <37 weeks of gestation), term (delivery ≥37 weeks of gestation) and postpartum pre-eclampsia. The maternal syndrome of pre-eclampsia is driven by a dysfunctional placenta, which releases factors into maternal blood causing systemic inflammation and widespread maternal endothelial dysfunction. Available treatments target maternal hypertension and seizures, but the only 'cure' for pre-eclampsia is delivery of the dysfunctional placenta and baby, often prematurely. Despite decades of research, the aetiology of pre-eclampsia, particularly of term and postpartum pre-eclampsia, remains poorly defined. Significant advances have been made in the prediction and prevention of preterm pre-eclampsia, which is predicted in early pregnancy through combined screening and is prevented with daily low-dose aspirin, starting before 16 weeks of gestation. By contrast, the prediction of term and postpartum pre-eclampsia is limited and there are no preventive treatments. Future research must investigate the pathogenesis of pre-eclampsia, in particular of term and postpartum pre-eclampsia, and evaluate new prognostic tests and treatments in adequately powered clinical trials.
