Purpose: Severe hypercalcemia resulting from hyperparathyroidism may result in adverse perinatal outcomes. The objective of this study was to evaluate maternal and neonatal outcomes among pregnant women with hyperparathyroidism using a population database., Methods: A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from 1999-2015. ICD-9 codes were used to identify women diagnosed with hyperparathyroidism during pregnancy. Perinatal outcomes between pregnant women with and without hyperparathyroidism were compared. Multivariate logistic regression, controlling for age, race, income, insurance type, hospital location, and comorbidities, evaluated the effect of hyperparathyroidism on perinatal outcomes., Results: Of 13,792,544 deliveries included over the study period, 368 were to women with hyperparathyroidism. The overall incidence of hyperparathyroidism was 2.7/100,000 births, increasing from 1.6 to 5.2/100,000 births over the study period ( p  < 0.0001). Women with hyperparathyroidism were older and had more comorbidities, such as obesity, and pre-gestational hypertension and diabetes. Relative to the comparison group, women with hyperparathyroidism were more likely to deliver preterm, OR 1.69 (95% CI 1.24-2.29), to develop preeclampsia, 3.14 (2.30-4.28), and to deliver by cesarean, 1.69 (1.36-2.09). Infants born to mothers with hyperparathyroidism were more likely to be growth restricted, 1.83 (1.08-3.07), and to be diagnosed with a congenital anomaly, 4.21 (2.09-8.48)., Conclusion: Hyperparathyroidism during pregnancy is associated with a significant increase in adverse perinatal outcomes, including preeclampsia, preterm delivery, fetal growth restriction, and congenital anomalies. As such, pregnancies among women with hyperparathyroidism should be considered high-risk, and specialized care is recommended in order to minimize maternal and neonatal morbidity.

Objectives: To (1) define quality indicators, (2) describe care gaps, and (3) identify process issues in severe hypertension (sustained systolic blood pressure [BP] ≥160 mm Hg or diastolic BP ≥110 mm Hg) management at our tertiary care centre., Methods: Pregnant and postpartum persons diagnosed with a hypertensive disorder of pregnancy from 2018 to 2019 were identified. A retrospective cohort of patients with severe hypertension was constructed, and data were collected through chart review. Severe hypertension management was assessed according to defined quality indicators. Clinical characteristics were compared between participants with and without time-to-target BP within 60 minutes. Process issues were examined for each severe hypertension occurrence., Results: Of 608 participants with a hypertensive disorder of pregnancy, 90 (15%) experienced severe hypertension. Median time-to-target BP was 76 minutes (interquartile range 47-123 minutes), and target BP (<155/105 mm Hg) was achieved within 60 minutes in 31/90 (34%) participants. Appropriate antihypertensives for severe hypertension were used in 55/90 (61%), and time-to-treatment initiation was within 30 minutes in 42/54 (78%). Chronic hypertension and oral labetalol use were associated with delays in achieving target BP. Process issues related to severe hypertension management included inappropriate treatment (n = 35/90; 39%), failure to recognize severe hypertension as an emergency (n = 21/90; 23%), and delayed treatment initiation (n = 12/54; 22%)., Conclusion: We defined quality indicators for severe hypertension management. Time-to-target BP within 60 minutes was achieved in a minority of patients, and chronic hypertension was associated with delayed severe hypertension resolution. Process issues in severe hypertension management were described., (Copyright © 2023 The Society of Obstetricians and Gynaecologists of Canada/La Société des obstétriciens et gynécologues du Canada.

Background: The rate of cesarean delivery has increased in the United States over the last several decades. However, the rate of cesarean delivery on maternal request remains undetermined, and recent data on cesarean delivery on maternal request are lacking., Objective: This study aimed to describe the prevalence and temporal trends of cesarean delivery on maternal request in the United States and characterize the population of women who elect to undergo a cesarean delivery in the absence of fetal or maternal indications. Maternal outcomes between women who delivered by cesarean delivery on maternal request and those who did not were compared., Study Design: A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from 1999 to 2015. An algorithm based on International Classification of Diseases, Ninth Revision codes was created to identify patients who underwent a primary elective cesarean delivery in the absence of fetal or maternal indications. Maternal characteristics and outcomes between women who delivered by cesarean delivery on maternal request and those who did not were compared using descriptive and logistic regression analyses., Results: Of the 13,698,835 deliveries included throughout the study period, 228,586 were identified as cesarean delivery on maternal request. Rates of cesarean delivery on maternal request among all live births increased throughout the study period, from 1% in 1999 to 1.62% in 2015 (P<.0001). Women who delivered by cesarean delivery on maternal request were more likely to be >35 years of age, were in the highest income quartile, and have private insurance. Cesarean delivery on maternal request was associated with an increased risk of venous thromboembolism (odds ratio, 1.9; 95% confidence interval, 1.8-2.0), myocardial infarction (odds ratio, 6.3; 95% confidence interval, 3.8-10.4), sepsis (odds ratio, 5.6; 95% confidence interval, 4.7-6.6), disseminated intravascular coagulation (odds ratio, 2.9; 95% confidence interval, 2.3-3.7), death (odds ratio, 14.5; 95% confidence interval, 11.4-18.6), and prolonged hospital stay (odds ratio, 4.9; 95% confidence interval, 4.8-5.1) and a lower risk of postpartum hemorrhage (odds ratio, 0.7; 95% confidence interval, 0.7-0.7)., Conclusion: Our findings indicated that cesarean delivery on maternal request accounts for a small but increasing proportion of all cesarean deliveries in the United States. Cesarean delivery on maternal request was more prevalent among women with certain demographic characteristics, indicating that the option of cesarean delivery on maternal request may be more appealing or more frequently offered to a certain population of women. Although the overall risk of adverse events is low for individual births, population effects can result in increased morbidity and mortality. Therefore, the rates of cesarean delivery on maternal request should be monitored on a national level. Study findings were limited by the absence of a specific diagnostic code for cesarean delivery on maternal request., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Excluding pregnant people from Covid-19 clinical trials may lead to unintended harmful consequences. For this study, an online questionnaire was sent to physicians belonging to Canadian professional medical associations in order to evaluate their perspectives on the participation of pregnant women in Covid-19 clinical trials. The majority of respondents expressed support for including pregnant women in Covid-19 trials (119/165; 72%), especially those investigating therapies with a prior safety record in pregnancy (139/164; 85%). The main perceived barriers to inclusion identified were unwillingness of pregnant patients to participate and of treating teams to offer participation, the burden of regulatory approval, and a general "culture of exclusion" of pregnant women from trials. We describe why some physicians may be reluctant to include pregnant individuals in trials, and we identify barriers to the appropriate participation of pregnant people in clinical research., (© 2021 by The Hastings Center.
