Background Cesarean sections (CS) are believed to be associated with greater risks of postpartum VTE. Our objective was to systematically review the evidence on this association and on the absolute ...risk of VTE following CS. Methods We searched PubMed, Embase, and conference proceedings from 1980 to November 2015 for reports on the associations of delivery methods with postpartum VTE and on the incidence of VTE following CS. Studies on thrombophilia or recurrent VTE were excluded, and the search was restricted to prospective studies when assessing the incidence of VTE. Pooled relative and absolute risks were estimated with random effects models. Results The search retrieved 28 mostly retrospective observational studies comparing risks of VTE following CS and following vaginal deliveries (VD) (> 53,000 VTE events) and 32 prospective studies reporting risks of VTE following CS (218 VTE events). Compared with VD, the relative risk of VTE following CS ranged from 1 to 22, with a meta-analytic OR of 3.7 (95% CI, 3.0-4.6). Adjustment for age and BMI had a marginal influence on the estimated pooled OR. Associations were observed for both elective and emergency CS, with stronger estimates of associations for emergency CS. The pooled incidence was 2.6 VTE per 1,000 CS (95% CI, 1.7-3.5) and was greater in studies with a longer and better follow-up in the postpartum period (4.3 per 1,000 CS). Conclusions The risk of VTE was fourfold greater following CS than following VD; seemed independent of other VTE risk factors; and was greater following emergency CS than following elective CS. On average, three in 1,000 women will develop a VTE following CS.
To evaluate the effect of aspirin dose on the incidence of all gestational age preeclampsia and preterm preeclampsia.
Electronic databases (Cochrane, PubMed, Scopus, ClinicalTrials.gov and the Web of ...Science) were searched for articles published between January 1985 and March 2019 with no language restrictions.
We followed the PRIMSA guidelines and utilized Covidence software. Articles were screened by 2 independent reviewers, with discrepancies settled by an independent 3rd party. Study selection criteria were randomized trials comparing aspirin for prevention of all gestational age and preterm preeclampsia to placebo or no antiplatelet treatment in women aged 15-55 years with moderate or high-risk factors according to the list of risk factors from American College of Obstetricians and Gynecologists and United States Preventive Services Task Force guidelines. The quality of trials was assessed using the Cochrane risk of bias tool. The data were pooled using a random-effects meta-analysis comparing aspirin at doses of <81, 81, 100, and 150 mg. Pre-specified outcomes were all gestational age and preterm preeclampsia.
Of 1,609 articles screened, 23 randomized trials, which included 32,370 women, fulfilled the inclusion criteria. In preterm preeclampsia, women assigned at random to 150 mg experienced a significant 62% reduction in risk of preterm preeclampsia (RR = 0.38; 95% CI: 0.20-0.72; P = 0.011). Aspirin doses <150 mg produced no significant reductions. The number needed to treat with 150 mg of aspirin was 39 (95% CI: 23-100). There was a maximum 30% reduction in risk of all gestational age preeclampsia at all aspirin doses.
In this meta-analysis, based on indirect comparisons, aspirin at a dose greater than the current, recommended 81 mg was associated with the highest reduction in preterm preeclampsia. Our meta-analysis is limited due to the deficiency of homogeneous high evidence data available in the literature to date; however, it may be prudent for clinicians to consider that the optimal aspirin dose may be higher than the current guidelines advise. Future research to compare the efficacy aspirin doses greater than 81 mg is recommended.

Pregnant women with mild chronic hypertension were randomly assigned to receive medication targeting a normal blood pressure (<140/90 mm Hg) or to receive no treatment unless severe hypertension ...(>160/105 mm Hg) developed. The incidence of adverse maternal and neonatal outcomes was significantly lower in the active-treatment group, without an increase in low birth weight.
Our aim was to conduct a post participation survey of respondent experiences with in-home remote patient monitoring via telehealth for blood pressure monitoring of women with postpartum hypertension. ...We hypothesized that the in-home remote patient monitoring application will be implemented with strong fidelity and have positive patient acceptability.
This analysis was a planned secondary analysis of a non-randomized controlled trial of telehealth with remote blood pressure patient monitoring for postpartum hypertension compared to standard outpatient monitoring in women with a hypertension-related diagnosis during pregnancy. In collaboration with survey experts, we developed a 41-item web-based survey to assess 1) perception of quality of care received, 2) ease of use/ease to learn the telehealth program, 3) effective orientation of equipment, 4) level of perceived security/privacy utilizing telehealth and 5) problems encountered. The survey included multiple question formats including Likert scale responses, dichotomous Yes/No responses, and free text. We performed a descriptive analysis on all responses and then performed regression analysis on a subset of questions most relevant to the domains of interest. The qualitative data collected through open ended responses was analyzed to determine relevant categories. Intervention participants who completed the study received the survey at the 6-week study endpoint.
Sixty six percent of respondents completed the survey. The majority of women found the technology fit easily into their lifestyle. Privacy concerns were minimal and factors that influenced this included age, BMI, marital status, and readmissions. 95% of women preferred remote care for postpartum follow-up, in which hypertensive type, medication use and ethnicity were found to be significant factors in influencing location of follow-up. Most women were satisfied with the devices, but rates varied by hypertensive type, infant discharge rates and BMI.
Postpartum women perceived the telehealth remote intervention was a safe, easy to use method that represented an acceptable burden of care and an overall satisfying method for postpartum blood pressure monitoring.

Introduction/Objective: Indomethacin is an effective tocolytic to prevent extremely preterm birth. Prior studies have associated antenatal indomethacin exposure with adverse preterm neonatal ...intestinal and neurological outcomes. Indomethacin is a nephrotoxic medication that may also affect preterm neonatal kidneys. We sought to evaluate the effect of antenatal indomethacin on extremely preterm neonatal kidney function and acute kidney injury (AKI) in the first week of age.
Methods: A retrospective cohort study was conducted on neonates born < 29 weeks at a level III neonatal intensive care unit (NICU) from January 2018-April 2019. Serum creatinine (sCr) values and urine output (UOP) in the first seven days of age and the neonate's peak serum creatinine within the first 30 days were evaluated. Neonatal AKI was defined by the modified neonatal Kidney Disease Improving Global Outcomes (KDIGO) definition including urine output.
Results: 17 of the 55 neonates meeting criteria for this study were exposed to indomethacin. The average gestational age at birth was similar between study groups. Maternal preeclampsia was more common among women who did not receive indomethacin (p = 0.021). Indomethacin exposed neonates received more gentamicin (p = 0.024). Overall, staging of the neonatal AKI did not differ significantly between the study groups, regardless of how it was quantified (sCr or UOP) or the duration of time in which the injury developed (7 days or 30 days). Separate analysis of sCr and UOP in the first seven days also failed to show any statistically significant differences between the two groups.
Conclusion: In this small cohort study of extremely preterm neonates, those born to mothers treated with indomethacin did not have an increased incidence of AKI compared to neonates born to unexposed mothers. Although no statistically significant differences in UOP or sCr were found, they deserve further evaluation in adequately powered prospective clinical trials. Future prospective studies with long-term follow-up utilizing advanced biomarkers are needed to determine how antenatal indomethacin affects extremely preterm neonatal kidney function in the NICU, during childhood, and as adults.
Many patients do not engage in health behaviors that can control common, chronic illnesses. Clinicians have opportunities to promote health behaviors yet may lack skills for coaching effectively ...about health behaviors. Our aims are to: present definitions of coaching, propose concepts for coaching about behavior change from two theories, share theory-guided research on behavior change relevant to ambulatory care settings, and delineate how concepts from these theories can guide coaching.
In our discussion, we explain how two behavioral theories are complementary and applicable to coaching, present empirical support for these theories, and describe applications of these concepts for practice.
Self-determination theory can guide clinicians in how to interact with patients to meet patients’ psychological needs, to promote health behaviors, and subsequent health status. Self-regulation theory can guide coaches in what concepts to address for behavior change. These complementary theories have been supported in rigorous research with adult populations in ambulatory care settings.

To investigate the longitudinal blood pressure (BP) pattern of women with hypertensive disorders of pregnancy (HDP) preconception through the postpartum day (PPD) 42.
A retrospective study of women ...(≥15 years old) diagnosed with an HDP antenatally or postpartum, who were enrolled prospectively in a postpartum remote BP monitoring program between 3/2017 and 5/2020. BPs were collected from 47-time points: preconception, each trimester, delivery day, and 42 days postpartum. Analysis was conducted utilizing a mixed-effects longitudinal model.
Primary outcome was the longitudinal BP patterns. Secondary outcomes were the timing of BP stabilization (BPs < 140/90 mmHg for ≥48 h) and resolution (stabilized without antihypertensive medication use).
Our final analysis included 897 of the 964 eligible women. The peak systolic and diastolic BPs were on PPDs 3, 4, 5, and 5, 6, 7, respectively. Systolic BP fell below the preconception level after PPD15; diastolic BP reached its plateau after PPD17 and remained above the preconception level till PPD42 (p < .001). Postpartum BP peaked with the highest percentage of BP spikes on PPDs 4-7. The median survival times to BP stabilization and resolution were PPDs 11 (95% CI: 10-12) and 23 (95% CI: 21-25), respectively. By PPD42, 91.0% and 74.1% of women achieved BP stabilization and resolution, respectively.
This study data could be used to develop evidence-based recommendations for women with an HDP. Diastolic BPs remaining significantly higher than the preconception level indicates the long-term risk of cardiovascular disease. In our cohort, 26% of women had unresolved hypertension by PPD42, which reinforces the necessity to ensure long-term follow-up.
Given rapid advancements in medical science, it is often challenging for the busy clinician to remain up-to-date on the fundamental and multifaceted aspects of preventive cardiology and maintain ...awareness of the latest guidelines applicable to cardiovascular disease (CVD) risk factors. The “American Society for Preventive Cardiology (ASPC) Top Ten CVD Risk Factors 2021 Update” is a summary document (updated yearly) regarding CVD risk factors. This “ASPC Top Ten CVD Risk Factors 2021 Update” summary document reflects the perspective of the section authors regarding ten things to know about ten sentinel CVD risk factors. It also includes quick access to sentinel references (applicable guidelines and select reviews) for each CVD risk factor section. The ten CVD risk factors include unhealthful nutrition, physical inactivity, dyslipidemia, hyperglycemia, high blood pressure, obesity, considerations of select populations (older age, race/ethnicity, and sex differences), thrombosis/smoking, kidney dysfunction and genetics/familial hypercholesterolemia. For the individual patient, other CVD risk factors may be relevant, beyond the CVD risk factors discussed here. However, it is the intent of the “ASPC Top Ten CVD Risk Factors 2021 Update” to provide a succinct overview of things to know about ten common CVD risk factors applicable to preventive cardiology.

Severe infection with COVID-19 virus in pregnancy offers unique management challenges for the obstetrician and critical care specialist. We report the case of a woman at 26 weeks of gestation with ...acute respiratory distress syndrome secondary to COVID-19 infection treated with dexamethasone, remdesivir, convalescent plasma and mechanical ventilation. Cesarean delivery was performed at 29 weeks due to worsening maternal status. This case offers insight into the assessment and successful use of treatment strategies, including dexamethasone, remdesivir, convalescent plasma, early prone positioning, conservative fluid management, permissive hypoxia and low tidal volume parameters with ventilator support for pregnancies affected by severe COVID-19 infection.
•Dexamethasone offers maternal and fetal benefits in severe COVID-19 infection.•Lung protective ventilator settings can be used in pregnancy in COVID-related acute respiratory distress syndrome.•Use of prone positioning for improved ventilation is well tolerated in pregnancy.•Fetal heart rate tracing is a clinical indicator of maternal oxygenation status.•Permissive hypoxia can be used to prevent barotrauma and advance fetal maturity.

Hypertensive disorders of pregnancy are one of the leading causes of maternal morbidity and mortality worldwide. Management of these conditions can pose many clinical dilemmas and can be particularly ...challenging during the immediate postpartum period. Models for predicting and managing postpartum hypertension are necessary to help address this clinical challenge.
This study aimed to evaluate predictive models of blood pressure spikes in the postpartum period and to investigate clinical management strategies to optimize care.
This was a retrospective cohort study of postpartum women who participated in remote blood pressure monitoring. A postpartum blood pressure spike was defined as a blood pressure measurement of ≥140/90 mm Hg while on an antihypertensive medication and a blood pressure measurement of ≥150/100 mm Hg if not on an antihypertensive medication. We identified 3 risk level patient clusters (low, medium, and high) when predicting patient risk for a blood pressure spike on postpartum days 3 to 7. The variables used in defining these clusters were peak systolic blood pressure before discharge, body mass index, patient systolic blood pressure per trimester, heart rate, gestational age, maternal age, chronic hypertension, and gestational hypertension. For each risk cluster, we focused on 2 treatments, namely (1) postpartum length of stay (<3 days or ≥3 days) and (2) discharge with or without blood pressure medications. We evaluated the effectiveness of the treatments in different subgroups of patients by estimating the conditional average treatment effect values in each cluster using a causal forest. Moreover, for all patients, we considered discharge with medication policies depending on different discharge blood pressure thresholds. We used a doubly robust policy evaluation method to compare the effectiveness of the policies.
A total of 413 patients were included, and among those, 267 (64.6%) had a postpartum blood pressure spike. The treatments for patients at medium and high risk were considered beneficial. The 95% confidence intervals for constant marginal average treatment effect for antihypertensive use at discharge were −3.482 to 4.840 and − 5.539 to 4.315, respectively; and for a longer stay they were −5.544 to 3.866 and −7.200 to 4.302, respectively. For patients at low risk, the treatments were not critical in preventing a blood pressure spike with 95% confidence intervals for constant marginal average treatment effect of 1.074 to 15.784 and −2.913 to 9.021 for the different treatments. We considered the option to discharge patients with antihypertensive use at different blood pressure thresholds, namely (1) ≥130 mm Hg and/or ≥80 mm Hg, (2) ≥140 mm Hg and/or ≥90 mm Hg, (3) ≥150 mm Hg and/or ≥ 100 mm Hg, or (4) ≥160 mm Hg and/or ≥ 110 mm Hg. We found that policy (2) was the best option with P<.05.
We identified 3 possible strategies to prevent outpatient blood pressure spikes during the postpartum period, namely (1) medium- and high-risk patients should be considered for a longer postpartum hospital stay or should participate in daily home monitoring, (2) medium- and high-risk patients should be prescribed antihypertensives at discharge, and (3) antihypertensive treatment should be prescribed if patients are discharged with a blood pressure of ≥140/90 mm Hg.
