525 Maternal morbidity and pregnancy outcomes in teens vs. adults with hypertensive disorders of pregnancy

Abstract Hypertensive disorders of pregnancy (HDP) are a leading cause of severe maternal morbidity (SMM), yet mediation by cesarean delivery is largely unexplored. We investigated the association between HDP and SMM in a cohort of deliveries at a safety-net institution in Atlanta, Georgia, during 2016–2018. Using multivariable generalized linear models, we estimated adjusted risk differences, adjusted risk ratios, and 95% confidence intervals for the association between HDP and SMM. We examined interactions with cesarean delivery and used mediation analysis with 4-way decomposition to estimate excess relative risks. Among 3,723 deliveries, the SMM rate for women with and without HDP was 124.4 per 1,000 and 52.0 per 1,000, respectively. The adjusted risk ratio for the total effect of HDP on SMM was 2.55 (95% confidence interval (CI): 2.15, 3.39). Approximately 55.2% (95% CI: 25.7, 68.5) of excess relative risk was due to neither interaction nor mediation, 24.9% (95% CI: 15.4, 50.0) was due to interaction between HDP and cesarean delivery, 9.6% (95% CI: 3.4, 15.2) was due to mediation, and 10.3% (95% CI: 5.4, 20.3) was due to mediation and interaction. HDP are a potentially modifiable risk factor for SMM; implementing evidence-based interventions for the prevention and treatment of HDP is critical for reducing SMM risk.

Introduction: Maternal mortality and morbidity are important indicators of the quality of health-care services. Obstetric admissions to an intensive care unit may be considered a marker of maternal morbidity. The aim of this study was to determine the incidence, maternal morbidity and mortality of pregnant and postpartum women who required admission to the intensive care unit.Material and Methods: Retrospective analysis of all the obstetric patients admitted to the intensive care unit between 2000 and 2017. Results: Ninety-three women required admission to intensive care (0.7 per 1000 deliveries, 0.8% of all adult admissions). Mean age was 30.3 years, mean gestational age was 33.6 weeks, 51 (54.8%) were primiparous, nine (9.7%) were pregnant of twins and five (5.4%) had not been followed during pregnancy. Eighty-four (90.3%) were admitted after immediate delivery. The most common reasons for admission were hypertensive disorders of pregnancy (35.5%) and obstetric haemorrhage (24.7%). Median length of stay was five days. Transfusion of blood products was needed in 23 (57.0%), artificial ventilation in 50 (53.8%) and use of vasopressors in 21 (22.6%). We observed four maternal deaths (4.3%). Most patients (95.7%) successfully recovered and were transferred to other departments. Sequential Organ Failure Assessment score was significantly associated with maternal mortality.Discussion: Our results are comparable to those obtained in other studies. Maternal mortality was comparable to maternal mortality in developed countries.Conclusion: The incidence of obstetric admissions to the intensive care unit was 0.8% and 0.7 per 1000 deliveries. Hypertensive disorders of pregnancy were the main causes of admission. Maternal mortality was 4.3%. Studies of maternal morbidity are important and can help to improve the quality of health care services.

Background: Hypertensive disorders of pregnancy constitute a major cause of maternal morbidity and mortality. Pre-eclampsia/eclampsia ranks second only to haemorrhage as a specific, direct cause of maternal mortality. A number of markers have been under study for the early detection of this disease. The study aims to evaluate the predictive value of sFlt-1/PlGF ratio for preeclampsia.Methods: This study was conducted in the Department of Gynaecology and Obstetrics of ASCOMS hospital, Jammu for a period of 6 months from Jan 2019 to June 2019. 50 antenatal patients attending the outpatient department with risk factors for developing preeclampsia were enrolled in the study. Their sFlT-1/PIGF ratio was determined at gestational age of 20 weeks to 37 weeks and its predictive value was evaluated.Results: In the present study, 8 patients developed preeclampsia subsequently. The mean sFlt-1/PIGF ratio values were significantly higher in the patients who developed preeclampsia (73.5) than who did not develop the disease (26.07). The positive predictive value at 1 week was 41.66% and negative predictive value was 100%. At 4 weeks, positive predictive value was 66.66% and negative predictive value was 100%.Conclusions: The present study suggests sFlt-1/PIGF ratio values are useful marker was a predictor of preeclampsia and values >38 were associated with preeclampsia. It is more useful in ruling out preeclampsia than ruling in the disease.

ABSTRACT STUDY QUESTION What were the risks with regard to the pregnancy outcomes of patients who conceived by frozen-thawed embryo transfer (FET) during a hormone replacement cycle (HRC-FET)? SUMMARY ANSWER The patients who conceived by HRC-FET had increased risks of hypertensive disorders of pregnancy (HDP) and placenta accreta and a reduced risk of gestational diabetes mellitus (GDM) in comparison to those who conceived by FET during a natural ovulatory cycle (NC-FET). WHAT IS KNOWN ALREADY Previous studies have shown that pregnancy and live-birth rates after HRC-FET and NC-FET are comparable. Little has been clarified regarding the association between endometrium preparation and other pregnancy outcomes. STUDY DESIGN, SIZE, DURATION A retrospective cohort study of patients who conceived after HRC-FET and those who conceived after NC-FET was performed based on the Japanese assisted reproductive technology registry in 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS The pregnancy outcomes were compared between NC-FET (n = 29 760) and HRC-FET (n = 75 474) cycles. Multiple logistic regression analyses were performed to investigate the potential confounding factors. MAIN RESULTS AND THE ROLE OF CHANCE The pregnancy rate (32.1% vs 36.1%) and the live birth rate among pregnancies (67.1% vs 71.9%) in HRC-FET cycles were significantly lower than those in NC-FET cycles. A multiple logistic regression analysis showed that pregnancies after HRC-FET had increased odds of HDPs [adjusted odds ratio, 1.43; 95% confidence interval (CI), 1.14–1.80] and placenta accreta (adjusted odds ratio, 6.91; 95% CI, 2.87–16.66) and decreased odds for GDM (adjusted odds ratio, 0.52; 95% CI, 0.40–0.68) in comparison to pregnancies after NC-FET. LIMITATIONS, REASONS FOR CAUTION Our study was retrospective in nature, and some cases were excluded due to missing data. The implication of bias and residual confounding factors such as body mass index, alcohol consumption, and smoking habits should be considered in other observational studies. WIDER IMPLICATIONS OF THE FINDINGS Pregnancies following HRC-FET are associated with higher risks of HDPs and placenta accreta and a lower risk of GDM. The association between the endometrium preparation method and obstetrical complication merits further attention. STUDY FUNDING/COMPETING INTEREST(S) No funding was obtained for this work.
