BACKGROUND: An institutional standardized, nurse-initiated protocol was implemented to improve the recognition of and response to perinatal hypertensive emergency.
OBJECTIVE: The primary aim was to evaluate if the rate of guideline-based treatment of perinatal hypertensive emergency improved with implementation of the protocol.
METHODS: This quality improvement initiative was developed by a multidisciplinary team and consisted of clinician and nursing education and the implementation of a standardized, nurse-initiated severe hypertension protocol. The project took place in three phases: pre-implementation (July 2020-October 2020), implementation (November 2020-June 2021), and sustainment (July 2021-May 2022). The primary aim was to increase guideline-based treatment of hypertensive emergency among pregnant and postpartum persons. Guideline-based treatment was defined as repeat blood pressure within 30 minutes of severe hypertension to diagnose hypertensive emergency, antihypertensive medication administration within 30 minutes of diagnosis, and appropriately timed repeat blood pressure following treatment. Process measures included time to confirm the diagnosis, initiate the protocol, antihypertensive medication administration, repeat blood pressure after antihypertensive medication administration, and administration of a secondary dose as appropriate. Balancing measures included maternal intensive care unit admission, clinically significant maternal hypotension, fetal demise, neonatal birthweight, and Apgar <7 at 5 minutes. Data were evaluated using between-subjects statistics and a run chart was developed to assess relationship between the protocol and changes in guideline-based treatment over time.
RESULTS: Overall, 503 hypertensive emergency encounters were identified during the project period (98 [20%] pre-implementation, 172 [34%] implementation, 233 [46%] sustainment). There were higher rates of persons with chronic hypertension and who self-identified as non-Hispanic Black race in the sustainment phase compared to the other phases. Guideline-based treatment increased from 18.4% pre-implementation to 75.1% in sustainment (p<0.001). Each component of guideline-based treatment also improved significantly from pre-implementation to sustainment (p<0.001). No episodes of clinically significant maternal hypotension occurred in any phase. There were four maternal intensive care unit admissions and three fetal demises during the initiative; none were related to hypertensive emergency.
CONCLUSIONS: The nurse-initiated protocol for treatment of hypertensive emergency significantly increased guideline-based treatment of perinatal hypertensive emergency, reduced time to diagnose and treat hypertensive emergency, and increased the number of patients receiving treatment when indicated. This protocol was pragmatic, utilizing resources already available on obstetric units. Use of similar protocols may be considered at institutions providing obstetric care to improve recognition of and response to hypertensive emergency which may decrease maternal and neonatal morbidity and mortality related to hypertensive emergency.

BACKGROUND: Sexual minority (SM) individuals (e.g., those with same-sex attractions/partners or who identify as lesbian/gay/bisexual) experience a host of physical and mental health disparities. However, little is known about sexual orientation-related disparities in gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP; gestational hypertension [gHTN] and preeclampsia).
OBJECTIVE: To estimate disparities in GDM, gHTN and preeclampsia by sexual orientation.
METHODS: We used data from the Nurses\' Health Study II-a cohort of nurses across the US enrolled in 1989 at 25-42 years of age-restricted to those with pregnancies ≥20 weeks gestation and non-missing sexual orientation data (63,518 participants; 146,079 pregnancies). Our primary outcomes were GDM, gHTN and preeclampsia, which participants reported for each of their pregnancies. Participants also reported their sexual orientation identity and same-sex attractions/partners. We compared the risk of each outcome in pregnancies among heterosexual participants with no same-sex experience (reference) to those among SM participants overall and within subgroups: (1) heterosexual with same-sex experience, (2) mostly heterosexual, (3) bisexual and (4) lesbian/gay participants. We used modified Poisson models to estimate risk ratios (RR) and 95% confidence intervals (CI), fit via weighted generalised estimating equations, to account for multiple pregnancies per person over time and informative cluster sizes.
RESULTS: The overall prevalence of each outcome was ≤5%. Mostly heterosexual participants had a 31% higher risk of gHTN (RR 1.31, 95% CI 1.03, 1.66), and heterosexual participants with same-sex experience had a 31% higher risk of GDM (RR 1.31, 95% CI 1.13, 1.50), compared to heterosexual participants with no same-sex experience. The magnitudes of the risk ratios were high among bisexual participants for gHTN and preeclampsia and among lesbian/gay participants for gHTN.
CONCLUSIONS: Some SM groups may be disparately burdened by GDM and HDP. Elucidating modifiable mechanisms (e.g., structural barriers, discrimination) for reducing adverse pregnancy outcomes among SM populations is critical.

This review seeks to evaluate the levels of health-related quality of life (HRQoL) among pregnant women experiencing pregnancy-induced hypertension (PIH). It also aims to identify the specific aspects of HRQoL most impacted by PIH during pregnancy and determine the existence of effective interventions to enhance the HRQoL of these pregnant women. A systematic literature search was conducted in the following databases: PUBMED, SCOPUS, Google Scholar, and EMBASE using the following keywords: Health-related quality of life; pregnancy; pregnancy-induced hypertension; quality of life; gestational hypertension. Among the 32 studies assessed, only eight met the criteria for inclusion, exhibiting a good quality based on assessment with both AXIS (Appraisal Tool for Cross-Sectional Studies) and CASP (Critical Appraisal Skills Programme) checklists. The findings indicate a decline in HRQoL among pregnant women with gestational hypertension, notably affecting both physical and mental dimensions. Furthermore, some studies provided recommendations for interventions that healthcare professionals could employ to improve poor HRQoL levels. Limited research has focused on the HRQoL in pregnant women with PIH. Compared to their healthy counterparts, pregnant women experiencing PIH exhibit a decrease in their HRQoL. It\'s crucial for healthcare practitioners to proactively address the HRQoL of these pregnant women using effective strategies to mitigate this decline. This approach aims to safeguard both pregnant women and their fetuses from potential complications associated with lower HRQoL levels.

Pheochromocytoma, a rare but potentially serious condition, poses challenges in timely identification, especially during pregnancy due to misconceptions about pregnancy-related hypertension causes. However, paroxysmal symptoms heighten diagnostic suspicion. The diagnosis relies on biochemical confirmation of catecholamine hypersecretion followed by imaging for tumor localization. When diagnosed at or after 24 weeks, alpha-adrenoceptor blockers are recommended during pregnancy to manage catecholamine excess, delaying tumor removal until viability or post-delivery. The rarity of this condition during pregnancy, coupled with diagnostic and management challenges, underscores its importance for obstetric professionals in addressing hypertensive control, delivery timing, and surgical intervention.

BACKGROUND: Endometriosis is a chronic and debilitating disease that can affect the entire reproductive life course of women, with potential adverse effects on pregnancy. The aim of the present study is to investigate the association between hypertensive disorders in pregnancy and endometriosis.
METHODS: Relevant articles were searched from the Cochrane Library, PubMed, Scopus and Web of Science from inception up to December 2023. The full-text observational studies published in English that had a confirmed diagnosis of endometriosis were included. The case group included pregnant women diagnosed with endometriosis at any stage, while the control group consisted of pregnant women who had not been previously diagnosed with endometriosis. Two authors extracted and analyzed the data independently. Disagreements were reconciled by reviewing the full text by a third author. Endnote X9 was used for screening and data extraction. We used fixed and random effects models in Review Manager 5.3 to analyze the pooled data. The quality of the included studies was assessed using the Downs and Black checklist.
RESULTS: Out of the 9863 articles reviewed, 23 were selected for meta-analysis. According to the results of this study, there was an association between endometriosis and gestational hypertension (OR = 1.11, 95% CI: 1.06, 1.16; I2 = 45%, P < 0.00001; N = 8), pre-eclampsia (OR = 1.26, 95% CI: 1.18, 1.36; I2 = 37%, P < 0.00001; N = 12), and hypertensive disorders in pregnancy (OR = 1.13, 95% CI: 1.06, 1.21; I2 = 8%, P = 0.0001; N = 8).
CONCLUSIONS: This study confirmed that endometriosis may elevate the risk of developing gestational hypertensive disorders. Raising awareness of this issue will help to identify effective strategies for screening and early diagnosis of hypertensive disorders in pregnancy.

BACKGROUND: Gestational hypertension (GHTN) and preeclampsia are established risk indicators for chronic hypertension. While recurrence is associated with a greater risk, it is unclear whether there are differences in risk when these gestational complications occur for the first time in an earlier pregnancy versus first occurrence in a subsequent one. We hypothesized that the absence of recurrence reflects a transition toward a lower hypertension risk trajectory, whereas a new occurrence in a later pregnancy indicates a transition toward elevated risk.
RESULTS: We analyzed linked data in Quebec, Canada, from public health care insurance administrative databases and birth, stillbirth, and death registries. Our retrospective cohort study included mothers with 2 singleton deliveries between April 1990 and December 2012. The primary exposure was patterns of GHTN or preeclampsia across 2 pregnancies (GHTN/preeclampsia in neither, first only, second only, or both). The outcome was incident chronic hypertension. We performed an adjusted multivariable Cox regression analysis. Among 431 980 women with 2 singleton pregnancies, 27 755 developed hypertension during the follow-up period. Compared with those without GHTN/preeclampsia, those with GHTN/preeclampsia only in the first pregnancy had a 2.7-fold increase in hazards (95% CI, 2.6-2.8), those with GHTN/preeclampsia only in the second had a 4.9-fold increase (95% CI, 4.6-5.1), and those with GHTN/preeclampsia in both pregnancies experienced a 7.3-fold increase (95% CI, 6.9-7.6). Patterns and estimates were similar when we considered GHTN and preeclampsia separately.
CONCLUSIONS: The magnitude of hypertension risk is associated with the number and sequence of GHTN/preeclampsia-affected pregnancies. Considering both allows more personalized risk estimates.

UNASSIGNED: To the best of our knowledge, numerous observational studies have linked pregnancy complications to increased risks of diabetes and cardiovascular disease (CVD), causal evidence remains lacking. Our aim was to estimate the association of adverse pregnancy outcomes with diabetes and cardiovascular diseases.
UNASSIGNED: A two-sample Mendelian randomization (MR) analysis was employed, which is not subject to potential reverse causality. Data for pregnancy complications were obtained from the FinnGen consortium. For primary analysis, outcome data on diabetes, related traits, stroke, and coronary heart disease (CHD) were extracted from the GWAS Catalog, MAGIC, MEGASTROKE, and CARDIoGRAMplusC4D consortium. The MAGIC and UKB consortium datasets were used for replication and meta-analysis. Causal effects were appraised using inverse variance weighted (IVW), weighted median (WM), and MR-Egger. Sensitivity analyses were implemented with Cochran\'s Q test, MR-Egger intercept test, MR-PRESSO, leave-one-out (LOO) analysis and the funnel plot.
UNASSIGNED: Genetically predicted gestational diabetes mellitus (GDM) was causally associated with an increased diabetes risk (OR=1.01, 95% CI=1-1.01, P<0.0001), yet correlated with lower 2-hour post-challenge glucose levels (OR=0.89, 95% CI=0.82-0.97, P=0.006). Genetic liability for pregnancy with abortive outcomes indicated decreased fasting insulin levels (OR=0.97, 95% CI=0.95-0.99, P=0.02), but potentially elevated glycated hemoglobin levels (OR=1.02, 95% CI=1.01-1.04, P=0.01). Additionally, hypertensive disorders in pregnancy was tentatively linked to increased risks of stroke (OR=1.11, 95% CI=1.04-1.18, P=0.002) and CHD (OR=1.3, 95% CI=1.2-1.4, P=3.11E-11). Gestational hypertension might have a potential causal association with CHD (OR=1.11, 95% CI=1.01-1.22, P=0.04). No causal associations were observed between preterm birth and diabetes, stroke, or CHD.
UNASSIGNED: The findings of this study provide genetic evidence that gestational diabetes, pregnancy with abortive outcomes, and hypertensive disorders in pregnancy may serve as early indicators for metabolic and cardiovascular risks. These insights are pivotal for the development of targeted screening and preventive strategies.

BACKGROUND: It is unknown whether women with pregnancy-onset asthma are predisposed to worse pregnancy outcomes compared with women with pre-pregnancy asthma.
OBJECTIVE: To explore whether pregnancy-onset asthma leads to worse perinatal outcomes compared with pre-pregnancy asthma.
METHODS: Women who were discharged with a diagnosis of asthma and gave birth to a live singleton were included in this retrospective cohort analysis. Women were separated into groups based on whether the asthma was diagnosed during or before pregnancy. We compared clinical characteristics, perinatal outcomes, and asthma exacerbations (AEs) between groups.
RESULTS: A total of 335 women were included in this study, 39 of whom (11.6%) had pregnancy-onset asthma and 296 had pre-pregnancy asthma. All pregnant women in the pregnancy-onset group experienced AEs during pregnancy. The proportion of chronic hypertension, chronic hypertension with superimposed preeclampsia, and spontaneous preterm births in the pregnancy-onset group was significantly higher than that in the pre-pregnancy asthma group. After adjusting for age, body mass index, onset of asthma during pregnancy, and severity of AEs through multivariate analysis, pregnancy-onset asthma was an independent risk factor for spontaneous preterm birth (adjusted odds ratio = 7.71; 95% CI, 1.30-46.12) and severe AE was an independent risk factor for gestational hypertension and preeclampsia (adjusted odds ratio = 3.58; 95% CI, 1.30-9.87).
CONCLUSIONS: During pregnancy, pregnancy-onset asthma in women is associated with an exacerbation of the condition. Obstetricians should be vigilant for signs of asthma onset during pregnancy. Other health care providers should watch for symptoms of gestational hypertension and preeclampsia in pregnant women with preexisting or new-onset asthma.

BACKGROUND: . The long-term impact of gestational complications on cardiovascular outcomes in women remains a subject of debate.
OBJECTIVE: To assess the 5-year risk of cardiovascular events and all-cause mortality in women with gestational diabetes and hypertension.
METHODS: Retrospective study utilising an health research network(TriNetX). The primary outcome was the composite risk of a cardiovascular event within 5 years with secondary outcomes being its components (all-cause death, acute heart failure, myocardial infarction, ischaemic stroke). Women were categorised into 8 different groups based on the ICD-codes for pregnancy related complications recorded 9 months before the delivery:1) gestational diabetes,2) gestational hypertension,3) gestational diabetes with gestational hypertension,4) gestational diabetes with gestational hypertension without pre-eclampsia or eclampsia,5) gestational diabetes with pre-eclampsia or eclampsia,6) gestational hypertension without pre-eclampsia or eclampsia,7) pre-eclampsia or eclampsia,and 8) no gestational complications. Cox-regression analyses were used to produce hazard ratios (HRs) and 95 % confidence intervals (CI) before and after propensity score matching (PSM).
RESULTS: We identified, 24,402 women with gestational diabetes and gestational hypertension and 920,478 without gestational complications. After PSM, compared to women without pregnancy complications, women with gestational diabetes and gestational hypertension had a higher 5-year risk of composite outcome(HR 2.25,95 %CI 2.02-2.51), all-cause death(HR 1.64,95 %CI 1.31-2.06), acute heart failure(HR 2.06,95 %CI 1.69-2.52), myocardial infarction(HR 2.46,95 %CI 1.93-3.14), and ischemic stroke(HR 2.37,95 %CI 2.06-2.74). Women who experienced pre-eclampsia or eclampsia showed the highest risk of primary and secondary outcomes.
CONCLUSIONS: Gestational complications are associated with worse long-term cardiovascular outcomes. There is a clear call to action required to improve the longitudinal management of gestational complications to improve women\'s long-term health.
