Abstract
Venous thromboembolism (VTE), including both pulmonary embolism (PE) and deep vein thrombosis (DVT), is the leading cause of maternal death in developed countries. Pregnancy is associated with an increased risk of VTE due to physiologic changes during the obstetric period that promote a hypercoagulable state. Appropriate use of prophylactic anticoagulants can decrease the event rate of thrombus formation in at-risk patients. In the United States, there is not a validated risk-assessment tool for VTE in obstetric patients or a clear consensus on initiation and optimal dosing strategy for the prophylactic use of anticoagulants. This article reviews the mechanism of coagulation disturbance that leads to an increased risk of VTE in obstetric patients, as well as the available literature surrounding pharmacologic prophylaxis.

Wu Y, Shan D, Chen Q, Hu Y. Could the YEARS algorithm be applied to evaluate suspected pulmonary embolism in hospitalized women after cesarean section? Int J Gynaecol Obstet 2024; 167:374-382. [PMID: 38747718 DOI: 10.1002/ijgo.15573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 04/14/2024] [Accepted: 04/20/2024] [Indexed: 09/25/2024]
Abstract
OBJECTIVE To evaluate the effectiveness of the YEARS algorithm for excluding pulmonary embolism (PE) in hospitalized women after cesarean section. METHODS This retrospective study included postpartum women who gave birth by cesarean section and received computed tomography pulmonary angiography (CTPA) because of suspected PE in the obstetric department between 2015 and 2021. We used the YEARS algorithm in these women retrospectively and assessed its performance to evaluate whether the algorithm could be reliably applied in such cases. RESULTS In all, 225 women were included in the study, of whom 29 (12.9%) women were positive for PE according to the results of CTPA. Upon retrospective application of the YEARS algorithm, 188 (83.6%) women had no YEARS items, while 37 (16.4%) women had YEARS items. Combining the results with D-dimer levels revealed that only 12 (5.3%) women did not need to undergo CTPA, and none showed PE. CONCLUSION The YEARS algorithm could be applied to exclude PE in hospitalized women in the early post-cesarean period. However, the specificity of the YEARS algorithm was very low, and the D-dimer cut-off for ruling out PE in women after early cesarean section should be further studied and optimized.

Abstract
(1) Background: The three factors within the Virchow triad play the leading role in the development of deep vein thrombosis (DVT) during pregnancy. (2) Methods: This research approaches the various risk factors associated with DVT and its most representative complications, pulmonary thromboembolism and cerebral venous thrombosis, in pregnant and postpartum women across a 15-year period (2007-2021). (3) Results: A total of 201 out of 287 patients with DVT had associated risk factors, while 86 did not present with any. Out of the 201 patients with risk factors, 47 developed pulmonary thromboembolism, while 12 experienced cerebral thrombosis. The statistical analysis of risk factors involved in DVT revealed high significance for obesity (OR 3.676; CI 2.484-5.439), gestational diabetes (OR 3.394; CI 2.101-5.483), hypertension (OR 2.325; CI 1.591-3.397), preeclampsia (OR 4.753; CI 2.342-9.645), thrombophilia (OR 12.138; CI 8.973-16.417), and varicose veins (OR 9.678; CI 7.321-12.793); for pulmonary thromboembolism, there was high significance for obesity (OR 7.867; CI 4.297-14.401), hypertension (OR 2.605; CI 1.246-5.446), preeclampsia (OR 7.483; CI 2.346-23.872), thrombophilia (OR 11.035; CI 5.910-20.602), and varicose veins (OR 6.837; CI 3.665-12.757); and for cerebral thromboembolism (CTE), the risk factors identified were obesity (OR 6.755; CI 1.954-23.347), hypertension (OR 1.167; CI 0.155-8.770), preeclampsia (OR 9.655; CI 1.283-72.672), and thrombophilia (OR 33.275; CI 12.884-85.939). (4) Conclusions: Obesity was the only significant factor found to influence DVT, pulmonary embolism and CTE risks, and hereditary thrombophilia was the main factor influencing the risk for pulmonary thromboembolism and CTE. Systemic lupus erythematosus and gestational diabetes revealed conflicting results that require further investigation.

A More Selective vs a Standard Risk-Stratified, Heparin-Based, Obstetric Thromboprophylaxis Protocol. JAMA 2024; 332:310-317. [PMID: 38935391 PMCID: PMC11211987 DOI: 10.1001/jama.2024.8684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 04/24/2024] [Indexed: 06/28/2024]
Abstract
Importance In 2016, our institution adopted a pregnancy-related venous thromboembolism (VTE) prophylaxis protocol based on American College of Obstetricians and Gynecologists guidelines that recommended postpartum heparin-based chemoprophylaxis (enoxaparin) based on a risk-stratified algorithm. In response to increased wound hematomas without significant reduction in VTE using this protocol, a more selective risk-stratified approach was adopted in 2021. Objective To evaluate outcomes of the more selective risk-stratified approach to heparin-based obstetric thromboprophylaxis (enoxaparin) protocol. Design, Setting, and Participants Retrospective observational study of 17 489 patients who delivered at a single tertiary care center in the southeast US between January 1, 2016, and December 31, 2018 (original protocol), and between December 1, 2021, and May 31, 2023 (more selective protocol). Patients receiving outpatient anticoagulation for active VTE or high VTE risk during pregnancy were excluded. Exposure Standard risk-stratified and more selective postpartum VTE chemoprophylaxis protocols. Main Outcomes and Measures The primary outcome was clinical diagnosis of wound hematoma up to 6 weeks pos tpartum. The secondary outcome was new diagnosis of VTE up to 6 weeks post partum. We compared baseline characteristics and outcomes between groups and estimated adjusted odds ratios with 95% CIs of primary and secondary outcomes using the original protocol group as reference. Results Of 17 489 patients included in the analysis, 12 430 (71%) were in the original protocol group and 5029 (29%) were in the more selective group. Rates of chemoprophylaxis decreased from 16% (original protocol) to 8% (more selective protocol). Patients in the more selective group were more likely to be older, be married, and have obesity or other comorbidities (hypertension, diabetes, cardiac disease). Compared with the original protocol, the more selective protocol was associated with a decrease in any wound hematoma (0.7% vs 0.3%; adjusted odds ratio [aOR], 0.38; 95% CI, 0.21-0.67), specifically due to a lower rate of superficial wound hematomas (0.6% vs 0.3%; aOR, 0.43; 95% CI, 0.24-0.75). There was no significant increase in VTE or individual types of VTE (0.1% vs 0.1%; aOR, 0.40; 95% CI, 0.12-1.36). Conclusions and Relevance A more selective risk-stratified approach to an enoxaparin thromboprophylaxis protocol for VTE was associated with decreased rates of wound hematomas without increased rates of postpartum VTE.

[PMID: 38574855 DOI: 10.1016/j.ajogmf.2024.101362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 03/18/2024] [Accepted: 03/28/2024] [Indexed: 04/06/2024]
Abstract
Preoperative preparation for cesarean delivery is a multistep approach for which protocols should exist at each hospital system. These protocols should be guided by the findings of this review. The interventions reviewed and recommendations made for this review have a common goal of decreasing maternal and neonatal morbidity and mortality related to cesarean delivery. The preoperative period starts before the patient's arrival to the hospital and ends immediately before skin incision. The Centers for Disease Control and Prevention recommends showering with either soap or an antiseptic solution at least the night before a procedure. Skin cleansing in addition to this has not been shown to further decrease rates of infection. Hair removal at the cesarean skin incision site is not necessary, but if preferred by the surgical team then clipping or depilatory creams should be used rather than shaving. Preoperative enema is not recommended. A clear liquid diet may be ingested up to 2 hours before and a light meal up to 6 hours before cesarean delivery. Consider giving a preoperative carbohydrate drink to nondiabetic patients up to 2 hours before planned cesarean delivery. Weight-based intravenous cefazolin is recommended 60 minutes before skin incision: 1-2 g intravenous for patients without obesity and 2 g for patients with obesity or weight ≥80 kg. Adjunctive azithromycin 500 mg intravenous is recommended for patients with labor or rupture of membranes. Preoperative gabapentin can be considered as a way to decrease pain scores with movement in the postoperative period. Tranexamic acid (1 g in 10-20 mL of saline or 10 mg/kg intravenous) is recommended prophylactically for patients at high risk of postpartum hemorrhage and can be considered in all patients. Routine use of mechanical venous thromboembolism prophylaxis is recommended preoperatively and is to be continued until the patient is ambulatory. Music and active warming of the patient, and adequate operating room temperature improves outcomes for the patient and neonate, respectively. Noise levels should allow clear communication between teams; however, a specific decibel level has not been defined in the data. Patient positioning with left lateral tilt decreases hypotensive episodes compared with right lateral tilt, which is not recommended. Manual displacers result in fewer hypotensive episodes than left lateral tilt. Both vaginal and skin preparation should be performed with either chlorhexidine (preferred) or povidone iodine. Placement of an indwelling urinary catheter is not necessary. Nonadhesive drapes are recommended. Cell salvage, although effective for high-risk patients, is not recommended for routine use. Maternal supplemental oxygen does not improve outcomes. A surgical safety checklist (including a timeout) is recommended for all cesarean deliveries.

Is early bilateral compression ultrasonography and D-dimer monitoring appropriately for prophylaxis and diagnosis of deep venous thrombosis after cesarean section women: a single-center observation study of Chinese Han population. BMC Pregnancy Childbirth 2024; 24:181. [PMID: 38454334 PMCID: PMC10918993 DOI: 10.1186/s12884-024-06372-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 02/26/2024] [Indexed: 03/09/2024] Open
Abstract
BACKGROUND Venous thromboembolism (VTE) is most prevalent among parturients following a cesarean section (CS). The objective of this study was to assess the practical utility of bilateral compression ultrasonography (CUS) of the lower limbs, coupled with D-dimer monitoring, in the early diagnosis of VTE within the Han Chinese population. METHODS Our prospective observational study included 742 women who underwent CUS and D-dimer testing on the first day post-CS. Subsequently, telephone or outpatient follow-ups were conducted until 42 days postpartum. States of hypercoagulation and thrombosis, as indicated by CUS, were classified as CUS abnormal. A D-dimer level ≥ 3 mg/l was considered the D-dimer warning value. Early ambulation and mechanical prophylaxis were universally recommended for all parturients post-CS. A sequential diagnostic strategy, based on the 2015 RCOG VTE risk-assessment tool, was employed. Therapeutic doses of low-molecular-weight heparin (LMWH) were administered for the treatment of thromboembolic disease. Prophylactic doses of LMWH were given for VTE prophylaxis in parturients with hypercoagulative status accompanied by D-dimer levels ≥ 3 mg/l. All high-risk women (RCOG score ≥ 4 points) were additionally treated with preventive LMWH. Statistical analyses were conducted using the R statistical software, with a two-sided P value < 0.05 considered statistically significant. RESULTS Fifteen cases of VTE and 727 instances without VTE were observed. The overall VTE rate post-CS was 2.02% (15/742), with 66.7% (10/15) being asymptomatic. Eleven patients received a VTE diagnosis on the first postpartum day. Among the 41 parturients exhibiting hypercoagulation ultrasound findings and D-dimer levels ≥ 3 mg/l, despite receiving pharmacological VTE prophylaxis with LMWH, 4.88% (2/41) in the high-risk group were eventually diagnosed with VTE. A total of 30.86% (229/742) exhibited normal ultrasound findings and D-dimer levels < 3 mg/l on the first day post-CS, with no VTE occurrences in the postpartum follow-up. According to RCOG's recommendation, 78.03% (579/742) of cesarean delivery women should receive prophylactic anticoagulation, while only 20.62% (153/742) met our criterion for prophylactic anticoagulation. CONCLUSION The strategy of timely routine bilateral CUS and D-dimer monitoring is conducive to the early diagnosis and treatment of VTE, significantly reducing the use of LMWH in the Chinese Han population.

Abstract
Background Pharmacological prophylaxis to prevent venous thromboembolism is currently recommended for women assessed as being at high risk of venous thromboembolism during pregnancy or in the 6 weeks after delivery (the puerperium). The decision to provide thromboprophylaxis involves weighing the benefits, harms and costs, which vary according to the individual's venous thromboembolism risk. It is unclear whether the United Kingdom's current risk stratification approach could be improved by further research. Objectives To quantify the current decision uncertainty associated with selecting women who are pregnant or in the puerperium for thromboprophylaxis and to estimate the value of one or more potential future studies that would reduce that uncertainty, while being feasible and acceptable to patients and clinicians. Methods A decision-analytic model was developed which was informed by a systematic review of risk assessment models to predict venous thromboembolism in women who are pregnant or in the puerperium. Expected value of perfect information analysis was used to determine which factors are associated with high decision uncertainty and should be the target of future research. To find out whether future studies would be acceptable and feasible, we held workshops with women who have experienced a blood clot or have been offered blood-thinning drugs and surveyed healthcare professionals. Expected value of sample information analysis was used to estimate the value of potential future research studies. Results The systematic review included 17 studies, comprising 19 unique externally validated risk assessment models and 1 internally validated model. Estimates of sensitivity and specificity were highly variable ranging from 0% to 100% and 5% to 100%, respectively. Most studies had unclear or high risk of bias and applicability concerns. The decision analysis found that there is substantial decision uncertainty regarding the use of risk assessment models to select high-risk women for antepartum prophylaxis and obese postpartum women for postpartum prophylaxis. The main source of decision uncertainty was uncertainty around the effectiveness of thromboprophylaxis for preventing venous thromboembolism in women who are pregnant or in the puerperium. We found that a randomised controlled trial of thromboprophylaxis in obese postpartum women is likely to have substantial value and is more likely to be acceptable and feasible than a trial recruiting women who have had a previous venous thromboembolism. In unselected postpartum women and women following caesarean section, the poor performance of risk assessment models meant that offering prophylaxis based on these models had less favourable cost effectiveness with lower decision uncertainty. Limitations The performance of the risk assessment model for obese postpartum women has not been externally validated. Conclusions Future research should focus on estimating the efficacy of pharmacological thromboprophylaxis in pregnancy and the puerperium, and clinical trials would be more acceptable in women who have not had a previous venous thromboembolism.

Abstract
Over the past three decades, substantial progress has been made in reducing maternal mortality worldwide. However, the historical focus on mortality reduction has been accompanied by comparative neglect of labour and birth complications that can emerge or persist months or years postnatally. This paper addresses these overlooked conditions, arguing that their absence from the global health agenda and national action plans has led to the misconception that they are uncommon or unimportant. The historical limitation of postnatal care services to the 6 weeks after birth is also a contributing factor. We reviewed epidemiological data on medium-term and long-term complications arising from labour and childbirth beyond 6 weeks, along with high-quality clinical guidelines for their prevention, identification, and treatment. We explore the complex interplay of human evolution, maternal physiology, and inherent predispositions that contribute to these complications. We offer actionable recommendations to change the current trajectories of these neglected conditions and help achieve the targets of Sustainable Development Goal 3. This paper is the third in a Series of four papers about maternal health in the perinatal period and beyond.

Abstract
OBJECTIVES We evaluate the rates and limitations of women's adherence to low molecular weight heparin (LMWH) after cesarean section (CS) in the Gaza Strip. METHODS Women who underwent CS were recruited consecutively. Communication offered to women, adherence to Venous thromboembolism (VTE), and its limiting factors were surveyed. RESULTS 281 women participated (mean age 27.9 years). 51.95% fully adhered to VTE prophylaxis. Causes of suboptimal adherence were: 51.1% did not feel VTE prophylaxis was important, 37.8% due to high drug cost, and 11.1% didn't receive a prescription for LMWH at discharge. Poor communication was evident as 48.8% of the sample did not receive any instructions about the technical method of LMWH injection, 45.6% did not receive any information about the clinical significance of heparin, and 74.7% were unaware of LMWH side effects. CONCLUSION There is inadequate adherence to VTE prophylaxis after CS among Gaza women, mostly due to a lack of appropriate communication but also due to drug costs.

Abstract
Introduction We aimed to evaluate the risk factors for the development of deep vein thrombosis (DVT) within one month after delivery in pregnant women of advanced maternal age undergoing cesarean section and explore the predictive value of fasting coagulation indicators in relation to the development of DVT. Methods A total of 176 eligible postpartum women were included in this study. Sixty-seven cases developed DVT within one month after delivery (DVT group), while 109 cases did not experience DVT (NDVT group). Within 24 hours after cesarean section, fasting coagulation indicators are measured. Coagulation system analysis was performed using the STA-R Evolution fully automated coagulation analyzer. Results The women who developed DVT were found to be older, had a higher proportion of women with previous childbirth experiences, and had a higher proportion of women with comorbidities. Our results revealed significant differences in the levels of activated partial thromboplastin time and prothrombin time between the NDVT group and the DVT group. In contrast, the DVT group displayed significantly higher levels of D-dimer, plasma fibrinogen and platelet count when compared to the NDVT group. The AUC for the combined test model was substantially higher compared to individual parameters. Discussion Multiple parameters of the postoperative coagulation state in the combined test model provided a more accurate prediction of DVT occurrence in elderly pregnant women after cesarean section.

Abstract
BACKGROUND There is large variation in recommended for postcesarean delivery venous thromboembolism (VTE) prophylaxis among commonly used guidelines. OBJECTIVES The aim of the study is to estimate implications of adoption of VTE prevention guidelines for rates of receipt of VTE prophylactic therapy and VTE following cesarean delivery (CD). METHODS We used administrative data from the 2015-2019 Nationalwide Readmissions Database to identify cesarean deliveries and rates of VTE stratified by risk factors, leading to different prophylactic strategies based on several national guidelines. We used input parameters from the literature to construct a hybrid decision tree/Markov model to project the implications of guideline adoption on VTE rates for the first 6 weeks following delivery. RESULTS Adoption of either the 2011 American College of Obstetricians and Gynecologists or the 2018 American Society for Hematology guidelines would avert a relatively small proportion (5%) of VTE cases, albeit with little low-molecular-weight heparin (LMWH) use (87-115 doses per 1000 CD patients). The 2012 American College of Chest Physicians guidelines were predicted to be more effective at averting VTE (21.2% reduction) with more LMWH usage (570 doses per 1000 deliveries). The 2015 Royal College of Obstetricians and Gynaecologists guidelines and universal use of 6 weeks of LMWH would avert an even larger proportion of cases (37.4% and 57.6%, respectively), at the cost of much higher rates of LMWH utilization (7233 doses per 1000 patients and 38 648 doses per 1000 patients). CONCLUSIONS Adoption of different guidelines would have notably varying implications for clinical practice and potential for alteration of the national rate of VTE following CD.

Abstract
Anticoagulant therapy is essential for the prevention or treatment of peripartum venous thromboembolism (VTE). Administration of a therapeutic dose of anticoagulant immediately after cesarean section may result in the formation of a rectus sheath hematoma. A 32-year-old Japanese woman delivered twin neonates by cesarean section at 37+5 weeks of gestation. After the removal of the placenta, the patient suddenly complained of left anterior chest pain and dyspnea with hypotension and desaturation, requiring the administration of oxygen and vasopressors. Postoperative contrast-enhanced computed tomography (CT) revealed pulmonary embolism and massive right ovarian vein thrombosis (OVT). An inferior vena cava filter was placed and continuous intravenous heparin was started. A rectus sheath hematoma was noted on postoperative day 2 (POD 2). On POD 5, heparin administration was temporarily discontinued because of an enlarged rectus sheath hematoma. Approximately 24 hours later, the hemoglobin level recovered, and heparin administration was resumed. No further expansion of the hematoma was observed. When a rectus sheath hematoma is formed due to treatment with a therapeutic dose of anticoagulant immediately after cesarean section for peripartum VTE, temporary suspension of anticoagulant administration is reasonable to prevent further expansion of the hematoma without fatal complication.

Abstract
BACKGROUND The use of medications during pregnancy is a common event worldwide. Monitoring medicine prescriptions in clinical practice is a necessary step in assessing the impact of therapeutic choices in pregnant women as well as the adherence to clinical guidelines. The aim of this study was to provide prevalence data on medication use before, during and after pregnancy in the Italian population. METHODS A retrospective prevalence study using administrative healthcare databases was conducted. A cohort of 449,012 pregnant women (15-49 years) residing in eight Italian regions (59% of national population), who delivered in 2016-2018, were enrolled. The prevalence of medication use was estimated as the proportion (%) of pregnant women with any prescription. RESULTS About 73.1% of enrolled women received at least one drug prescription during pregnancy, 57.1% in pre-pregnancy and 59.3% in postpartum period. The prevalence of drug prescriptions increased with maternal age, especially during the 1st trimester of pregnancy. The most prescribed medicine was folic acid (34.6%), followed by progesterone (19%), both concentrated in 1st trimester of pregnancy (29.2% and 14.8%, respectively). Eight of the top 30 most prescribed medications were antibiotics, whose prevalence was higher during 2nd trimester of pregnancy in women ≥ 40 years (21.6%). An increase in prescriptions of anti-hypertensives, antidiabetics, thyroid hormone and heparin preparations was observed during pregnancy; on the contrary, a decrease was found for chronic therapies, such as anti-epileptics or lipid-modifying agents. CONCLUSIONS This study represents the largest and most representative population-based study illustrating the medication prescription patterns before, during and after pregnancy in Italy. The observed prescriptive trends were comparable to those reported in other European countries. Given the limited information on medication use in Italian pregnant women, the performed analyses provide an updated overview of drug prescribing in this population, which can help to identify critical aspects in clinical practice and to improve the medical care of pregnant and childbearing women in Italy.

Abstract
Background and objectives Birth is a critical event in women's lives. Since humans have evolved to give birth in the context of social support, not having it in modern settings might lead to more complications during birth. Our aim was to model how emotional factors and medical interventions related to birth outcomes in hospital settings in Poland, where c-section rates have doubled in the last decade. Methodology We analysed data from 2363 low-risk primiparous women who went into labor with the intention of giving birth vaginally. We used a model comparison approach to examine the relationship between emotional and medical variables and birth outcome (vaginal or c-section), including sociodemographic control variables in all models. Results A model with emotional factors better explained the data than a control model (ΔAIC = 470.8); women with continuous personal support during labor had lower odds of a c-section compared to those attended by hospital staff only (OR = 0.12, 95% CI = 0.09 - 0.16). A model that included medical interventions also better explained the data than a control model (ΔAIC = 133.6); women given epidurals, in particular, had increased odds of a c-section over those who were not (OR = 3.55, 95% CI = 2.95 - 4.27). The best model included variables for both the level of personal support and the use of epidural (ΔAIC = 598.0). Conclusions and implications Continuous personal support during childbirth may be an evolutionarily informed strategy for reducing complications, including one of the most common obstetrical complications in modern hospital settings, the c-section.

BMC Pregnancy Childbirth 2023; 23:248. [PMID: 37055718 PMCID: PMC10099697 DOI: 10.1186/s12884-023-05561-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 03/30/2023] [Indexed: 04/15/2023] Open
Abstract
BACKGROUND Pregnant and puerperal women are high-risk populations for developing venous thromboembolism (VTE). Plasma D-dimer (D-D) is of good value in the diagnosis of exclusion of VTE in the nonpregnant population. Since there is no consensus reference range of plasma D-D applicable to pregnant and puerperal women, the application of plasma D-D is limited. To investigate the change characteristics and the reference range of plasma D-D levels during pregnancy and puerperium and to explore the pregnancy- and childbirth-related factors affecting plasma D-D levels and the diagnostic efficacy of plasma D-D for excluding VTE during early puerperium after caesarean section. METHODS A prospective cohort study was conducted with 514 pregnant and puerperal women (cohort 1), and 29 puerperal women developed VTE 24-48 h after caesarean section (cohort 2). In cohort 1, the effects of the pregnancy- and childbirth-related factors on the plasma D-D levels were analyzed by comparing the differences in plasma D-D levels between different groups and between different subgroups. The 95th percentiles were calculated to establish the unilateral upper limits of the plasma D-D levels. The plasma D-D levels at 24-48 h postpartum were compared between normal singleton pregnant and puerperal women in cohort 2 and women from the cesarean section subgroup in cohort 1, binary logistic analysis was used to analyze the relevance between plasma D-D level and the risk of VTE developing 24-48 h after caesarean section, and a receiver operating characteristic (ROC) curve was used to assess the diagnostic efficacy of plasma D-D for excluding VTE during early puerperium after caesarean section. RESULTS The 95% reference ranges of plasma D-D levels in the normal singleton pregnancy group were ≤ 1.01 mg/L in the first trimester, ≤ 3.17 mg/L in the second trimester, ≤ 5.35 mg/L in the third trimester, ≤ 5.47 mg/L at 24-48 h postpartum, and ≤ 0.66 mg/L at 42 days postpartum. The plasma D-D levels of the normal twin pregnancy group were significantly higher than those of the normal singleton pregnancy group during pregnancy (P < 0.05), the plasma D-D levels of the GDM group in the third trimester were significantly higher than those of the normal singleton pregnancy group (P < 0.05). The plasma D-D levels of the advanced age subgroup at 24-48 h postpartum were significantly higher than those of the nonadvanced age subgroup (P < 0.05), and the plasma D-D levels of the caesarean section subgroup at 24-48 h postpartum were significantly higher than those of the vaginal delivery subgroup (P < 0.05). The plasma D-D level was significantly correlated with the risk of VTE developing at 24-48 h after caesarean section (OR = 2.252, 95% CI: 1.611-3.149). The optimal cut-off value of plasma D-D for the diagnosis of exclusion of VTE during early puerperium after caesarean section was 3.24 mg/L. The negative predictive value for the diagnosis of exclusion of VTE was 96.1%, and the area under the curve (AUC) was 0.816, P < 0.001. CONCLUSIONS The thresholds of plasma D-D levels in normal singleton pregnancy and parturient women were higher than those of nonpregnant women. Plasma D-D had good value in the diagnosis of exclusion of VTE occurring during early puerperium after caesarean section. Further studies are needed to validate these reference ranges and assess the effects of pregnancy- and childbirth-related factors on plasma D-D levels and the diagnostic efficacy of plasma D-D for excluding VTE during pregnancy and puerperium.

Abstract
The pregnancy-related mortality rate in the United States is excessively high. The American Heart Association is dedicated to fighting heart disease and recognizes that cardiovascular disease, preexisting or acquired during pregnancy, is the leading cause of maternal mortality in the United States. Comprehensive scientific statements from cardiology and obstetrics experts guide the treatment of cardio-obstetric patients before, during, and after pregnancy. This scientific statement aims to highlight the role of specialized cardio-obstetric anesthesiology care, presenting a systematic approach to the care of these patients from the anesthesiology perspective. The anesthesiologist is a critical part of the pregnancy heart team as the perioperative physician who is trained to prevent or promptly recognize and treat patients with peripartum cardiovascular decompensation. Maternal morbidity is attenuated with expert anesthesiology peripartum care, which includes the management of neuraxial anesthesia, inotrope and vasopressor support, transthoracic echocardiography, optimization of delivery location, and consideration of advanced critical care and mechanical support when needed. Standardizing the anesthesiology approach to patients with high peripartum cardiovascular risk and ensuring that cardio-obstetrics patients have access to the appropriate care team, facilities, and advanced cardiovascular therapies will contribute to improving peripartum morbidity and mortality.

Abstract
Objectives To identify factors associated with adverse maternal outcomes during the coronavirus disease 2019 (COVID-19) pandemic. Methods This was a single-centre prospective cohort study at a maternity department in a public general hospital in Rio de Janeiro. All pregnant women evaluated for emergency care, labour and delivery, respiratory symptoms, obstetric reasons or medical reasons between May 2020 and March 2022 at the study institution were invited to enrol in this study. The endpoint was maternal mortality or intensive care unit (ICU) admission. Results In total, 1609 pregnant women were enrolled in this study. Of these, 25.5% (n=410) were infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) based on reverse transcription polymerase chain reaction or an antigen test. There were 21 deaths and 67 ICU admissions in 4% of the cohort. The incidence of severe maternal morbidity and mortality was higher during the Gamma wave than during the Delta wave (P=0.003). Vaccination conferred protection against the endpoint [relative risk (RR) 0.4, 95% confidence interval (CI) 0.1-0.9; P=0.0169]. Factors associated with severe morbidity and mortality included caesarean section (RR 3.7, 95% CI 1.7-7.9; P=0.0008), SARS-CoV-2 infection in the third trimester (RR 2.4, 95% CI 1.1-5.6; P=0.0006) and comorbidities (RR 3, 95% CI 1.8-5.2; P<0.0001). Conclusions COVID-19 was significantly associated with the risk of severe maternal morbidity and mortality. Immunization of pregnant women against COVID-19 was highly protective against adverse outcomes, and should be encouraged during pregnancy.

Abstract
Venous thromboembolism (VTE) is one of the leading causes of direct maternal deaths. It has been estimated that approximately 50% of these deaths are potentially preventable. The UK Confidential Enquiries into Maternal Deaths and the National Partnership for Maternal Safety have proposed strategies for the prevention of maternal deaths from VTE based on current guideline recommendations. The main strategies include: - Early recognition and comprehensive assessment of risk factors for VTE at different times from the beginning of pregnancy until patient's discharge from hospital. - Appropriate risk stratification using standardized VTE risk assessment tools (e.g. the Royal College Scoring System). - Risk-based antenatal and postnatal heparin thromboprophylaxis adjusting the heparin dosage and the duration of prophylaxis to the individual patient's risk. - Adequate management of heparin prophylaxis before and after delivery. - Preference of universal rather than selective post-cesarean heparin thromboprophylaxis and application of perioperative mechanical prophylaxis. - Avoidance of gaps in the postpartum prescription of heparin. - Good communication and cooperation between primary and secondary care including community midwifery staff in the postpartum period. - Immediate intravenous administration of (unfractionated) heparin, if pulmonary embolism is suspected. - Critical analysis of all thromboembolic events, particularly in association with maternal death to learn from failures and to realize, if and where improvement is needed. Adequate pharmacological thromboprophylaxis has the potential to reduce the risk of VTE by 60-70% in pregnant women at increased risk.

Abstract
Obesity is a chronic, progressive, relapsing, and treatable multifactorial, neurobehavioral disease. According to the World Health Organization, obesity affects 15% of women and has long-term effects on women's health. The focus of care in patients with obesity should be on optimizing health outcomes rather than on weight loss. Appropriate and common language, considering cultural sensitivity and trauma-informed care, is needed to discuss obesity. Pregnancy is a time of significant physiological change. Pre-, ante-, and postpartum clinical encounters provide opportunities for health optimization for parents with obesity in terms of, but not limited to, fertility and breastfeeding. Pre-existing conditions may also be identified and managed. Beyond pregnancy, women with obesity are at an increased risk for gastrointestinal and liver diseases, impaired kidney function, obstructive sleep apnea, and venous thromboembolism. Gynecological and reproductive health of women living with obesity cannot be dismissed, with accommodations needed for preventive health screenings and consideration of increased risk for gynecologic malignancies. Mental wellness, specifically depression, should be screened and managed appropriately. Obesity is a complex condition and is increasing in prevalence with failure of public health interventions to achieve significant decrease. Future research efforts should focus on interprofessional care and discovering effective interventions for health optimization.

Pregnancy and thrombosis risk for women without a history of thrombotic events: a retrospective study of the real risks. Thromb J 2022; 20:60. [PMID: 36203153 PMCID: PMC9535874 DOI: 10.1186/s12959-022-00419-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Accepted: 09/21/2022] [Indexed: 11/10/2022] Open
Abstract
Background During pregnancy and puerperium women are at high VTE risk. Current guidelines recommend dynamic VTE-risk assessment during pregnancy. Based on related RCOG-guidelines we constructed a digital VTE-risk assessment tool: PATrisks (www.PATrisks.com). Using this tool, we retrospectively evaluated the thrombotic risk in 742 women from our previous work, women who received thromboprophylaxis based on clinical experience for A) pregnancy complications, B) IVF treatment and C) prothrombotic tendency, in order to investigate whether that practice was justified according to the PATrisks scoring system for VTE prevention. Methods Women with pregnancy complications [Group-A: 445], women who had undergone IVF [Group-B:132] and women with a prothrombotic tendency (thrombophilia, family history of VTE, other) [Group-C:165] were assessed using the PATrisks scoring system for thrombotic risk. The women were assigned into one of the following risk categories: low (score ≤ 2), intermediate (score = 3) and high (score ≥ 4). Further analysis per risk factor type (pre-existing or obstetric) and for various combinations of them, was also performed. We evaluated thrombotic risk early in pregnancy, and in the peripartum period. Results The mean risk score antepartum was higher for women in Group B (3.3 in comparison with 1.9 and 2.0 in Group A and Group C respectively). Moreover, the risk score increased significantly postpartum for all Groups. The chi-square test also proved that there was a higher percentage of women at high or intermediate risk in group B compared to C before birth (55.3% vs.26.1% respectively, p < 0.0001, OR: 3.5, 95% CI: 2.2 – 5.7) and similarly after birth (85.6% vs. 56.4%, OR: 4.6, 95%CI: 2.6–8.2, p < 0.0001). In total 12 (1.6%) out of 742 women experienced thrombotic events, whether pre- or post-partum. Conclusions LMWHs are widely prescribed during pregnancy for a number of indications, even when a proven scientific basis for such a practice is lacking. However, a considerable percentage of women were already at VTE-risk according to PATrisks and might have derived an additional benefit from LMWH in the form of VTE prevention. The rational use of these drugs should be optimized by establishing and implementing routine risk assessment for all pregnant women and by providing the necessary education to healthcare professionals.

Abstract
INTRODUCTION Rates of delivery by cesarean section have gradually risen in many parts of the world, and it is regarded as a safe surgical procedure with expanded indications. We assessed maternal complications within 6 weeks postpartum after planned cesarean section and after planned vaginal delivery among patients without medical indication for cesarean section. MATERIAL AND METHODS This was a retrospective cohort study based on Swedish national registers and included 714 326 deliveries from 2008 to 2017. The study group consisted of cephalic, singleton, term pregnancies and excluded those with previous cesarean or pregnancy conditions that would qualify for cesarean section. We compared the risks of short-term complications between planned cesarean section and planned vaginal delivery. We obtained adjusted risk ratios (ARRs) using modified Poisson regression models adjusting for maternal age, parity, body mass index, smoking, country of birth, and county. RESULTS The outcomes studied were infections and thromboembolism. In the planned cesarean section group (n = 22 855), 15% had a postpartum infection compared with 10% in the planned vaginal group (n = 691 471) (ARR 1.6; 95% confidence interval [CI] 1.5-1.6), and 0.08% vs. 0.05% had a postpartum pulmonary embolism (ARR 1.7; 95% CI 1.0-2.6). The obtained risk estimates corresponded to "number needed to harm" estimates of 17 and 3448, respectively. When dividing the infections into subgroups, the risk of endometritis (ARR 1.2; 95% CI 1.1-1.3), wound infection (ARR 2.7; 95% CI 2.4-3.0), urinary tract infection (ARR 1.5; 95% CI 1.3-1.7), and mastitis (ARR 2.0; 1.9-2.2) was higher after planned cesarean section. CONCLUSIONS Among patients without medical indication for planned cesarean section, the risks of short-term maternal complications were higher with planned cesarean section than with planned vaginal delivery.

Abstract
Background Potentially preventable complications are monitored as part of the Maryland Hospital Acquired Conditions Program and are used to adjust hospital reimbursement. Few studies have evaluated racial-ethnic disparities in potentially preventable complications. Our study objective was to explore whether racial-ethnic disparities in potentially preventable complications after Cesarean delivery exist in Maryland. Methods We performed a retrospective observational cohort study using data from the Maryland Health Services Cost Review Commission database. All patients having Cesarean delivery, who had race-ethnicity data between fiscal years 2016 and 2020 were included. Multivariable logistic regression modeling was performed to estimate risk-adjusted odds of having a potentially preventable complication in patients of different race-ethnicity. Results There were 101,608 patients who had Cesarean delivery in 33 hospitals during the study period and met study inclusion criteria. Among them, 1,772 patients (1.7%), experienced at least one potentially preventable complication. Patients who had a potentially preventable complication were older, had higher admission severity of illness, and had more government insurance. They also had more chronic hypertension and pre-eclampsia (both P<0.001). Median length of hospital stay was longer in patients who had a potentially preventable complications (4 days vs. 3 days, P<0.001) and median hospital charges were approximately $4,600 dollars higher, (P<0.001). The odds of having a potential preventable complication differed significantly by race-ethnicity group (P=0.05). Hispanic patients and Non-Hispanic Black patients had higher risk-adjusted odds of having a potentially preventable complication compared to Non-Hispanic White patients, OR=1.26 (95% CI=1.05 to 1.52) and OR=1.17 (95% CI=1.03 to 1.33) respectively. Conclusions In Maryland a small percentage of patients undergoing Cesarean delivery experienced a potentially preventable complication with Hispanic and Non-Hispanic Black patients disproportionately impacted. Continued efforts are needed to reduce potentially preventable complications and obstetric disparities in Maryland.

Abstract
Pregnancy and puerperium increase the relative risk of venous thromboembolism (VTE) and the absolute risk remains low, around 1 per 1,000, with induced mortality of around 1 per 100,000. Analysis of large databases has helped specify the modes of presentation and risk factors (RF) whose impact is greater after than before childbirth, since VTE during pregnancy and post-partum obey different RFs. The evolution of the population concerned (mostly women over 35, obese, of multi-ethnicity undergoing medically assisted reproduction) affects the frequency of these RFs. Pulmonary embolism (PE) is over-represented after childbirth, but 30% of PE in pregnancy occurs without any RFs. Recommendations for prevention, mainly from expert groups, are heterogeneous and often discordant. Low molecular weight heparins (LMWH) are the mainstay of pharmacological thromboprophylaxis, in a field where randomized controlled studies are definitely lacking. VTE risk assessment in pregnancy must be systematic and repetitive. Risk assessment methods and scores are beginning to emerge to guide thromboprophylaxis and should be used more systematically. In the future, analyzing observational data from huge, nationwide registries and prospective cluster clinical trials may bring to light clinically relevant outcomes likely to feed comprehensive guidelines.

Abstract
The postpartum period represents the most critical time for pregnancy-associated venous thromboembolism (VTE), which is responsible for substantial morbidity and an important cause of maternal mortality. The estimated risk of postpartum VTE of about 1/1,000 deliveries can be modulated with the knowledge of maternal and obstetrical risk factors, although a precise estimate remains challenging in individuals. The use of postpartum low-dose low-molecular-weight heparins are tailored at intermediate and high-risk groups to reduce the thrombotic burden, despite the lack of dedicated randomized controlled trials. In this review, we will highlight the contemporary evidence on the risk of postpartum VTE, its stratification and its prevention. We will also discuss our knowledge on the values and preferences of women for postpartum thromboprophylaxis and their adherence to treatment.

Abstract
Background Telemedicine technology is widely used especially after the COVID-19 pandemic. It can be used to give medical advice as well as follow up with the patients at home in the outpatient setting. Low molecular weight heparin, such as enoxaparin, decreases the risk of venous thromboembolism after cesarean delivery. Objective assessing postcesarean women's adherence and experience to enoxaparin thromboprophylaxis regimens in the outpatient setting via telephone calls. Methods prospective cohort study was conducted in the Maternity and Children Hospital (MCH). Postcesarean women were interviewed at the postnatal ward in the MCH. The participants were followed up for 10 days of the delivery to assess their adherence to and experience with enoxaparin thromboprophylaxis. Suboptimal adherence was defined as the missing of one or more doses of enoxaparin. Results 170 women participated in this study. The majority of them (78.8%) were fully adherent to enoxaparin while 21.2% missed at least one dose. The most-reported causes for suboptimal adherence were perceived lack of necessity (44.4%), forget to take the injection (30.6%), feeling of high load going to the primary care unit to take injection (27.8%), and fear of injection (11.1%). Conclusion Telemedicine technology could be used to assess patients' adherence. The study results showed that the majority of participants were fully adherent to postcesarean enoxaparin but more than 20% of the participants were suboptimal adherent. Proper patient education techniques could influence patients' adherence and potentially decrease the risk of DVT in those populations.

Abstract
INTRODUCTION Puerperium is a critical period for patients affected by autoimmune rheumatic diseases for the risk of disease's flares and difficulties in treating lactating mothers. We want to summarize the literature data about psychological and pharmacological management of these patients and possible risk factors of disease's flares. AREAS COVERED We made a narrative review on recent studies about puerperium in rheumatic autoimmune diseases patients. EXPERT OPINION The physicians involved in management of patients during puerperium and in the follow-up of babies need to agree on maternal treatment because they need to reassure mothers about the safety of the prescribed medications. Furthermore, women with rheumatic diseases could present some musculoskeletal limitations and psychological problems, such as postpartum depression, which can lead to a sense of inadequacy to the mother's task. Families and physicians should be aware of these possible complications and support the new mothers providing correct counseling and practical help.

Abstract
Compared with nonpregnant women, pregnancy carries a four- to fivefold higher risk of venous thromboembolism (VTE). Despite increasing use of heparin prophylaxis in identified high-risk patients, pulmonary embolism still is the leading cause of maternal mortality in the western world. However, evidence on optimal use of thromboprophylaxis is scarce. Thrombophilia, the hereditary or acquired tendency to develop VTE, is also thought to be associated with complications in pregnancy, such as recurrent miscarriage and preeclampsia. In this review, the current evidence on optimal thromboprophylaxis in pregnancy is discussed, focusing primarily on VTE prevention strategies but also discussing the potential to prevent recurrent pregnancy complications with heparin in pregnant women with thrombophilia.

Abstract
BACKGROUND Exploratory laparotomy is considered the gold standard treatment for women with suspected uterine rupture. We aimed to investigate the feasibility and safety of laparoscopy as an alternative for laparotomy for the management of hemodynamically stable women with suspected postpartum uterine rupture. STUDY DESIGN We conducted a case series study including all women who were diagnosed with postpartum uterine rupture following vaginal delivery in a university-affiliated tertiary hospital, between November 2012 and July 2021. Until 2016, all women with suspected post-partum uterine rupture underwent laparotomy. Following 2016, a new tailored protocol based on laparoscopy for the management of postpartum uterine rupture in hemodynamically stable women was implemented. A comparison was made between women who underwent emergent laparoscopy to laparotomy. RESULTS During the study period 17 women were diagnosed with postpartum uterine rupture. From January 2012 to January 2016, four cases of uterine rupture were diagnosed, all of whom underwent laparotomy. Since 2016, thirteen cases of uterine rupture were diagnosed, of whom seven women (54%) underwent laparoscopy and 6 (46%) laparotomy. The median time interval from delivery to surgery was 70.5 min IQR (40-179) in the laparotomy group and 202 min IQR (70-485) in the laparoscopy group. The median operative time for laparoscopic surgery was 80 min (IQR 60-114) and 78 min (IQR 58-114) for the laparotomy group. Four women who underwent laparotomy (40%) and one who underwent laparoscopy (14.2%) were admitted to the intensive care unit following surgery. Blood products transfusion was required in six women who had laparotomy (60%) and one who had laparoscopy (14.2%). Median hospitalization period was 5 d IQR (4-5) in the laparotomy group as compared to 3 d IQR (3-4) in the laparoscopy group. There were no conversions to laparotomy in the laparoscopy group. CONCLUSIONS In hemodynamic stable women laparoscopic surgery for suspected postpartum uterine rupture is feasible and safe.

D-dimer level significance for deep vein thrombosis screening in the third trimester: a retrospective study. BMC Pregnancy Childbirth 2022; 22:21. [PMID: 34996371 PMCID: PMC8742329 DOI: 10.1186/s12884-021-04353-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 12/20/2021] [Indexed: 12/01/2022] Open
Abstract
Background Venous thromboembolism often develops after surgery and childbirth, resulting in death in some cases. Although early deep vein thrombosis (DVT) detection can predict pulmonary thromboembolism, there is no early screening method for DVT in pregnant women. Lack of consensus regarding significance or setting and cut-off value interpretation of D-dimer levels further impedes venous thromboembolism screening in pregnant women. This study aimed to examine the utility of third-trimester serum D-dimer levels as a screening test for DVT during pregnancy and to determine the frequency of asymptomatic DVT using lower-limb compression ultrasonography. Methods This single-center retrospective study included 497 pregnant women who underwent elective cesarean section at term in our hospital between January 2013 and December 2019. Serum D-dimer levels were preoperatively measured at 32–37 weeks’ gestation. The presence or absence of DVT in patients with serum D-dimer levels ≥ 3.0 µg/ml, the cut-off value, was examined using compression ultrasonography. In all patients, the presence or absence of clinical venous thrombosis (symptoms such as lower-limb pain, swelling, and heat sensation) was examined within 4 postoperative weeks. The Royal College of Obstetricians and Gynecologists Guideline 2015 was referred to determine risk factors for the onset of venous thrombosis during pregnancy. Among those, we examined the risk factors for DVT that result in high D-dimer levels during pregnancy. Results The median age and body mass index were 35 (20–47) years and 21.2 (16.4–41.1) kg/m2, respectively. Further, the median gestational age and D-dimer levels were 37 weeks and 2.1 (0.2–16.0) µg/ml, respectively. Compression ultrasonography was performed on 135 (26.5%) patients with a D-dimer level ≥ 3.0 µg/ml, with none of the patients showing DVT. All patients were followed up for 4 postoperative weeks, with none presenting with venous thromboembolism. Multivariate analysis showed that hypertensive disorders of pregnancy are an independent risk factor for venous thromboembolism that causes high D-dimer levels (odds ratio: 2.48, 95% confidence interval: 1.05–6.50, P = 0.04). Conclusion There may be low utility in screening for DVT using D-dimer levels in the third trimester. Further, prepartum asymptomatic DVT has a low frequency, indicating the low utility of compression ultrasonography.

Abstract
BACKGROUND The risk of venous thromboembolism after delivery is modified by mode of delivery, with the risk of venous thromboembolism being higher after cesarean delivery than vaginal delivery. The risk of venous thromboembolism after peripartum hysterectomy is largely unknown. OBJECTIVE This study aimed to compare the incidence and risk of venous thromboembolism among women who had and did not have a peripartum hysterectomy. Furthermore, we sought to compare the risk of venous thromboembolism after hysterectomy with other patient, pregnancy, and delivery risk factors known to be associated with venous thromboembolism. STUDY DESIGN This was a cross-sectional study of women with delivery encounters identified in the Nationwide Readmissions Database from October 2015 to December 2017. Delivery encounters and all variables of interest were identified using the International Classification of Diseases, Tenth Revision diagnosis and procedure codes. The incidence of venous thromboembolism during delivery and rehospitalizations within 6 weeks after discharge was compared among women who had and did not have a peripartum hysterectomy. Multivariable logistic regressions were used to estimate associations between venous thromboembolism and hysterectomy, adjusted for the following characteristics: maternal age, payer at time of delivery, obesity, hypertension, diabetes mellitus, tobacco use, multifetal gestation, peripartum infection, and peripartum hemorrhage. Similarly, venous thromboembolism risk was compared by mode of delivery, including hysterectomy. Diagnoses that may have been indications for peripartum hysterectomy were identified among patients who underwent a hysterectomy and compared between those who did and did not have venous thromboembolism. Analyses used survey weights to obtain population estimates. RESULTS Of the 4,419,037 women with deliveries, 5098 (11.5 per 10,000 deliveries) underwent a hysterectomy. Moreover, 110 patients (215.8 per 10,000 deliveries) were diagnosed with venous thromboembolism after hysterectomy. The risk of venous thromboembolism was significantly higher in women who underwent a hysterectomy than in women who did not have a hysterectomy (unadjusted odds ratio, 25.1 [95% confidence interval, 20.0-31.5]; adjusted odds ratio, 11.2 [95% confidence interval, 8.7-14.5]; P<.001). Comparing the risk of venous thromboembolism by mode of delivery, the unadjusted and adjusted incidences of venous thromboembolism were 6.9 (95% confidence interval, 6.5-7.3) and 7.4 (95% confidence interval, 6.9-7.8) per 10,000 deliveries among women after vaginal delivery without peripartum hysterectomy, 12.5 (95% confidence interval, 11.8-13.1) and 11.3 (95% confidence interval, 10.7-12.0) per 10,000 deliveries after cesarean delivery without hysterectomy; and 217.2 (95% confidence interval, 169.1-265.2) and 96.9 (95% confidence interval 76.9-126.5) per 10,000 deliveries after hysterectomy, regardless of mode of delivery. Of the 110 diagnoses of venous thromboembolism with peripartum hysterectomy, 89 (81%) occurred during delivery admission. Of the remaining 21 cases, 50% occurred within the first 10 days after discharge from delivery, and 75% occurred within 25 days after discharge. CONCLUSION These findings have demonstrated that peripartum hysterectomy is associated with a markedly increased risk of venous thromboembolism in the postpartum period, even when controlling for other known risk factors for postpartum thromboembolic events. Here, the incidence of venous thromboembolism after peripartum hysterectomy (2.2%) met some guideline-based risk thresholds for routine thromboprophylaxis, potentially for at least 2 weeks after delivery. Further investigation into the role of routine venous thromboembolism prophylaxis during and after delivery is needed.

Abstract
Sepsis-induced coagulopathy (SIC) scoring and D-dimer can be used to recognize COVID-19-induced coagulopathy, but the utility of these is largely unknown in the peripartum setting and leaves anticoagulation guidance unclear. We present the case of a critically ill postpartum patient with COVID-19 infection. This patient presented with clinical signs of COVID-19 infection and developed acute respiratory failure requiring invasive mechanical ventilation and subsequent cesarean delivery at 34 weeks. She initially improved postoperatively but deteriorated after postoperative day 5. She was found to have a very elevated D-dimer of 58 μg/mL and anticoagulation was escalated to full dosing. She required prolonged mechanical ventilation and deceased after developing gram-positive cocci bacteremia. This case demonstrates that recognition and management of COVID-19-associated coagulopathy can be confusing in the peripartum period and studies are needed to validate D-dimer and SIC scoring in this population of patients.

Abstract
INTRODUCTION The cesarean birth rate of 24.7% in the Military Health System (MHS) is lower than the national rate of 31.7%. However, the MHS rate remains higher than the 15-19% threshold associated with optimal maternal and neonatal outcomes. For active duty servicewomen, increased morbidity associated with cesarean birth is likely to affect the ability to meet the demands of assigned missions. Several decision-points occur during pregnancy and after the onset of labor that can affect the likelihood of cesarean birth including choice of provider, choice of hospital, timing of admission, and type of fetal monitoring. Evidence suggests the overuse of labor interventions may be associated with cesarean birth. Shared decision-making (SDM) is a strategy that can be used to carefully consider the risks, benefits, and alternatives of each labor intervention and is shown to be associated with positive patient outcomes. Most existing evidence explores SDM as an interaction that occurs between women and their providers. Few studies have explored the role of stakeholders such as spouses, family members, friends, labor and delivery nurses, and doulas. Furthermore, little is known about the process of SDM during labor and childbirth in the hospital setting, particularly for active duty women in the U.S. military. The purpose of this study was to propose a framework that explains the process of SDM during labor and childbirth in the hospital setting for active duty women in the U.S. military. MATERIALS AND METHODS A qualitatively driven mixed-methods approach was conducted to propose a framework that explains the process of SDM during labor and childbirth in the hospital setting for active duty women in the U.S. military. Servicewomen were recruited from September 2019 to April 2020. Semi-structured interviews were analyzed using a constructivist grounded theory approach. Participants also completed the SDM Questionnaire (SDM-Q-9). RESULTS Interviews were conducted with 14 participants. The sample included servicewomen from the Air Force (n = 7), Army (n = 4), and Navy (n = 3). Two participants were enlisted and the remainder were officers. Ten births occurred at military treatment facilities (MTFs) and six births took place at civilian facilities. The mean score on the SDM Questionnaire was 86.7 (±11.6), indicating a high level of SDM. Various stakeholders (e.g., providers, labor and delivery nurses, doulas, spouses, family members, and friends) were involved in SDM at different points during labor and birth. The four stages of SDM included gathering information, identifying preferences, discussing options, and making decisions. Events that most often involved SDM were deciding when to travel to the hospital, deciding when to be admitted, and selecting a strategy for pain management. Military factors involved in SDM included sources of information, selecting and working with civilian providers, and delaying labor interventions to allow time for an active duty spouse to travel to the hospital. CONCLUSIONS SDM during labor and birth in the hospital setting is a multi-stage process that involves a variety of stakeholders, including the woman, members of her social and support network, and healthcare professionals. Future research is needed to explore perspectives of other stakeholders involved in SDM.

Abstract
BACKGROUND Cesarean section is an independent risk factor for Venous thromboembolism (VTE). Low molecular weight heparin (LMWH) is extensively used for VTE prophylaxis after cesarean section. In this study, the effects of LMWH on coagulation and fibrinolysis after cesarean section and its clinical value were explored by studying the changes in laboratory indicators. METHODS Antepartum and postpartum peripheral blood of 44 pregnant women who underwent vaginal delivery and 44 pregnant women who underwent cesarean section treated per routine with LMWH thromboprophylaxis on the first day post-operatively were collected for the following tests: D-dimer; thrombotic markers such as thrombomodulin (TM), thrombin-antithrombin complex (TAT), α2-plasmin inhibitor-plasmin complex (PIC), and tissue plasminogen activator inhibitor complex (t-PAIC); thromboelastography. RESULTS Compared to the antepartum levels, PIC increased, TM, TAT, and t-PAIC decreased significantly in the parturients after a spontaneous vaginal delivery. Compared to the antepartum levels, parturients routinely treated with LMWH after cesarean section had higher PIC levels and lower D-dimer, TAT, and t-PAIC levels. Compared with parturients after vaginal delivery, parturients treated with LMWH after cesarean section had higher levels of TM, R, and MA, while there was no significant differences in the levels of D-dimer, TAT, PIC, t-PAIC, K, angle, LY30, and CI. CONCLUSION The coagulation and fibrinolytic systems in gravidas and parturients are in a high level of dynamic equilibrium. The levels of coagulation and fibrinolytic system activation were similar in parturients who were routinely treated with LMWH after cesarean section compared with parturients after a spontaneous vaginal delivery.

Abstract
Maternal morbidity and mortality as a result of cardiac disease is increasing in the United States. Safe management of pregnancy in women with heart disease requires appropriate anesthetic, cardiac, and obstetric care. The anesthesiologist should risk stratify pregnant patients based upon cardiac disease etiology and severity in order to determine the appropriate type of hospital and location within the hospital for delivery and anesthetic management. Increased intrapartum hemodynamic monitoring may be necessary and neuraxial analgesia and anesthesia is typically appropriate. The anesthesiologist should anticipate obstetric and cardiac emergencies such as emergency cesarean delivery, postpartum hemorrhage, and peripartum arrhythmias. This clinical review answers practical questions for the obstetric anesthesiologist and the nonsubspecialist anesthesiologist who regularly practices obstetric anesthesiology.

Abstract
INTRODUCTION Rates of cesarean section are rising in both developed and developing countries and while pregnancy and cesarean section are established as risk factors for thromboembolism and stroke, large population-based investigations focusing on all types of cardiovascular complication after delivery is missing. The aim was to analyze the risk of severe cardiovascular complications in the post-partum period following delivery by cesarean section. We also had a control group of vaginal deliveries and a reference group with nulliparas. MATERIALS AND METHODS This Swedish population-based study used three national registers between 2005 and 2017 and comprised a total of 1 165 684 individuals. Unselected register data was cross-linked and cardiovascular adverse events were identified by ICD diagnosis codes. 140 128 women (209 391 deliveries) were included in the cesarean group and 614 355 women (973 429 deliveries) in the vaginal control group. The reference group comprised 411 201 age-matched nulliparous women. The primary analysis was the risk of severe cardiovascular complications within 42 days of cesarean section or vaginal delivery. The secondary analysis evaluated risk factors for cardiovascular complications. RESULTS In the cesarean section group, 410 (0.20%) had a serious cardiovascular event within 42 days after delivery, and in the vaginal control group the number was 857 (0.09%). The risk of having an adverse cardiovascular event was significantly greater in the cesarean group (OR 2.23, CI 1.98 to 2.51) for all types of cardiovascular events. Risk factors were high BMI, preeclampsia, greater maternal age, tobacco use and acute cesarean delivery. CONCLUSIONS The absolute numbers on severe maternal morbidity after delivery are low. However, since almost half of the world's population are affected and the frequency of elective cesarean section continues to rise, a doubling of the risk for a severe cardiovascular event within 42 days of delivery is important to consider globally.

Abstract
OBJECTIVE The main purpose was to clarify the optimal D-dimer cutoff level during pregnancy to exclude deep vein thrombosis (DVT) prior to Cesarean section. The secondary purpose was to determine whether D-dimer can predict severe postpartum hemorrhage (PPH) in Cesarean section patients. METHODS Two hundred and seventy eight elective Cesarean section cases were enrolled. Clinical factors and blood parameters at 34-37 weeks of gestation were analyzed. To detect DVT, lower extremities veins were examined using color Doppler ultrasonography in cases with D-dimer level ≥ 1.5 μg/mL. In addition, postpartum blood loss amounts during Cesarean section were recorded. RESULTS Five DVT cases occurred in 250 singleton pregnancies, and 2 DVT cases occurred in 28 twin pregnancies. The overall incidence of DVT was 2.5%. The D-dimer level was higher in DVT cases than in non-DVT cases (3.84±1.97 vs. 2.31±1.48 μg/mL, P<0.01). The optimal D-dimer cutoff level was 2.6 μg/mL with a negative predic tive value of 99.5%, and sensitivity of 85.7%. PPH during Cesarean section was positively correlated with D-dimer level in all pregnancies. However, this relationship disappeared after excluding twin pregnancies. CONCLUSION A D-dimer level < 2.6 μg/mL at 34-37 weeks of gestation has the potential to exclude DVT. D-dimer can be an independent predictor for severe PPH for all Cesarean section cases, including twin pregnancies.

Abstract
OBJECTIVE This study aimed to compare neonatal outcomes for delivery at 36 weeks compared with 37 weeks in women with prior classical cesarean delivery (CCD). STUDY DESIGN This was a secondary analysis of the prospective observational cohort of the Eunice Kennedy National Institute for Child and Human Development's Maternal-Fetal Medicine Unit Network Cesarean Registry. Data on cases of repeat cesarean delivery (RCD) in the setting of a prior CCD were abstracted and used for analysis. This study compared outcomes of women who delivered at 360/7 to 366/7 versus 370/7 to 376/7 weeks. The primary outcome was a composite of adverse neonatal outcomes that included neonatal intensive care unit (NICU) admission, respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), hypoglycemia, mechanical ventilation, sepsis, length of stay ≥5 days, and neonatal death. A composite of maternal outcomes that included uterine rupture, blood transfusion, general anesthesia, cesarean hysterectomy, venous thromboembolism, maternal sepsis, intensive care unit admission, and surgical complications was also evaluated. RESULTS There were 436 patients included in the analysis. Women who delivered at 36 weeks (n = 176) were compared those who delivered at 37 weeks (n = 260). There were no differences in baseline characteristics. Delivery at 37 weeks was associated with a reduction in composite neonatal morbidity (24 vs. 34%, adjusted odds ratio [aOR] = 0.61 [0.31-0.94]), including a decrease in NICU admission rates (20 vs. 29%, aOR = 0.63 [0.40-0.99]), hospitalization ≥5 days (13 vs. 24%, aOR = 0.48 [0.29-0.8]), and RDS or TTN (9 vs. 19%, aOR = 0.43 [0.24-0.77]). There was no difference in adverse maternal outcomes (7 vs. 7%, aOR = 0.98 [0.46-2.09]). CONCLUSION Delivery at 37 weeks for women with a history of prior CCD is associated with a decrease in adverse neonatal outcomes, compared with delivery at 36 weeks. KEY POINTS · Classical cesarean section may have increased risk of uterine rupture in future pregnancies.. · This study compares outcomes of delivery at 370/7 to 376/7 versus 360/7 to 366/7 weeks.. · Delivery at 370/7 to 376/7 weeks was associated with decreased neonatal morbidity..

Abstract
BACKGROUND We report a case of afibrinogenemia in a lady, which was detected for the first time during her pregnancy. CASE A 24-year-old G4A3 was referred as a case of vaginal bleeding, after a cervical cerclage at 14 weeks of gestation. Elastometry targeted correction of coagulopathy was done initially, and targeted cryoprecipitate transfusion was done to maintain her gestation. She underwent induced vaginal delivery at 34 weeks of gestation. Fourteen days postpartum, the mother and child were discharged home well. CONCLUSION Coagulation factor deficiency should be considered as a rare cause for RPL. Serum fibrinogen level of 50-100 mg/dl during pregnancy seems to be a safe and adequate target to maintain in pregnant patients with afibrinogenemia.

Abstract
PURPOSE OF REVIEW Hormonal therapy is administered for multiple indications including contraception, alleviation of menopausal symptoms, hypogonadism, and more recently, gender-affirming care. Data suggest varying degrees of increased risk for venous thromboembolism (VTE). RECENT FINDINGS While oral progestin only methods do not appear to increase the risk of VTE, an association was seen with injection progestin contraception. Combined oral contraception with low-dose ethinyl estradiol and most types of progestin increased the risk of VTE compared with levonorgestrel-containing oral therapies. While transdermal hormonal contraception has been previously associated with increased VTE, a recently approved levonorgestrel and ethinyl estradiol transdermal patch reported low rates (<0.2%) in a large single-arm open-label study. Women receiving postmenopausal HRT experienced an increased risk of VTE in a dose-dependent manner when using oral hormonal therapy while nonoral methods, such as topical estrogen, did not appear to increase the risk of VTE. Some studies suggest no increased risk of VTE with testosterone therapy, however, a recent case-crossover study suggested higher VTE risk in men on testosterone, particularly men less than age 65 without hypogonadism. Route of administration had no effect on VTE rates. The estimated incidence rate of VTE risk in transgender women receiving estrogen therapy is 2.3 per 1000 person years, but may be imprecise due to heterogeneity in studies included in published meta-analyses. Surgical risk estimates are primarily indirect data drawn from cisgender patients receiving hormone therapy in the perioperative setting. SUMMARY Hormonal therapy affects VTE risk to varying degrees dependent on specific type of hormone, formulation, and occasionally route of delivery.

Abstract
BACKGROUND COVID-19 appears to be associated with a high risk of venous thromboembolism (VTE). We aimed to systematically review and meta-analyze the risk of clinically relevant VTE in patients hospitalized for COVID-19. METHODS This meta-analysis included original articles in English published from January 1st, 2020 to June 15th, 2020 in Pubmed/MEDLINE, Embase, Web of science, and Cochrane. Outcomes were major VTE, defined as any objectively diagnosed pulmonary embolism (PE) and/or proximal deep vein thrombosis (DVT). Primary analysis estimated the risk of VTE, stratified by acutely and critically ill inpatients. Secondary analyses explored the separate risk of proximal DVT and of PE; the risk of major VTE stratified by screening and by type of anticoagulation. RESULTS In 33 studies (n = 4009 inpatients) with heterogeneous thrombotic risk factors, VTE incidence was 9% (95%CI 5-13%, I2 = 92.5) overall, and 21% (95%CI 14-28%, I2 = 87.6%) for patients hospitalized in the ICU. Proximal lower limb DVT incidence was 3% (95%CI 1-5%, I2 = 87.0%) and 8% (95%CI 3-14%, I2 = 87.6%), respectively. PE incidence was 8% (95%CI 4-13%, I2 = 92.1%) and 17% (95%CI 11-25%, I2 = 89.3%), respectively. Screening and absence of anticoagulation were associated with a higher VTE incidence. When restricting to medically ill inpatients, the VTE incidence was 2% (95%CI 0-6%). CONCLUSIONS The risk of major VTE among COVID-19 inpatients is high but varies greatly with severity of the disease. These findings reinforce the need for the use of thromboprophylaxis in all COVID-19 inpatients and for clinical trials testing different thromboprophylaxis regimens in subgroups of COVID-19 inpatients. TRIAL REGISTRATION The review protocol was registered in PROSPERO International Prospective Register of Systematic Reviews ( CRD42020193369 ).

Abstract
IMPORTANCE A high cesarean delivery rate in US hospitals indicates the potential overuse of this procedure; however, underlying causes of the excessive use of cesarean procedures in the US have not been fully understood. OBJECTIVE To investigate the association between the probability of cesarean delivery at the patient-level and profit per procedure from cesarean deliveries. DESIGN, SETTING, AND PARTICIPANTS This observational, cross-sectional study used a nationally representative sample of hospital discharge data from women at low risk for cesarean birth who delivered newborns between 2010 and 2014 in the US. Data were gathered from the Nationwide Readmissions Database from the Healthcare Cost and Utilization Project, compiled by the Agency for Healthcare Research and Quality. Data cleaning and analyses were conducted between August 2019 and May 2020. EXPOSURES Hospital-level median value of profits from cesarean deliveries, defined as the difference between the charge and the cost for cesarean delivery calculated for each hospital. MAIN OUTCOMES AND MEASURES Our primary outcome was the individual-level probability of undergoing a cesarean delivery. We examined the association with the hospital-level median value of profits per procedure for cesarean delivery (defined as the difference between the charge and the cost for cesarean delivery) using hierarchical regression models adjusted for patient and hospital characteristics and year-fixed effects. RESULTS A total of 13 215 853 deliveries were included in our analyses (mean [SE] age, 27.4 [0] years), of which 2 202 632 (16.7%) were cesarean deliveries. After adjusting for potential confounders, pregnant women were more likely to have a cesarean birth when they delivered at hospitals with higher profits per procedure from cesarean deliveries. Women cared for at hospitals with the highest (adjusted odds ratio, 1.08; 95% CI, 1.02-1.14; P = .005) and second-highest profit quartiles (adjusted odds ratio, 1.07; 95% CI, 1.02-1.13; P = .007) had higher probabilities of a cesarean delivery compared with those cared for at hospitals in the lowest profit quartile. CONCLUSIONS AND RELEVANCE In this cross-sectional study of US nationally representative hospital discharge data, hospitals with higher profits per cesarean procedure were associated with an increased probability of delivering newborns through cesarean birth. These findings highlight the potential influence financial incentives play in determining a high cesarean delivery rate in the US.

Abstract
BACKGROUND Multiple guidelines regarding risk stratification for venous thromboembolism (VTE) incidence following cesarean delivery have been promulgated. OBJECTIVE To estimate the percentage of cesarean delivery patients for which pharmacologic VTE would be recommended and subsequent incidence of VTE, based on several guidelines. PATIENTS/METHODS This retrospective cohort study used data from the Nationwide Readmissions Database from October 2015 through December 2017. Diagnosis and procedure codes were used to identify patients undergoing cesarean delivery, incidence of VTE, and risk factors used to stratify risk in the existing guidelines. Time-to-event analysis was used to analyze data, stratified by risk categorization in 2011 American College of Obstetricians and Gynecologists (ACOG), 2012 American College of Chest Physicians (ACCP), 2015 Royal College of Obstetricians and Gynaecologists (RCOG), and 2018 American Society of Hematology (ASH) guidelines. RESULTS/CONCLUSIONS In a cohort of 1 235 149 cesarean deliveries, VTE incidence was 2.1 per 1000 deliveries at 330 days following delivery (95% confidence interval: 2.0-2.2). Proportions of patients that would be recommended for pharmacologic prophylaxis ranged from 0.2% in 2018 ASH guidelines to 73.4% in 2015 RCOG criteria. Among groups considered at elevated risk for VTE for which pharmacologic prophylaxis would be recommended, VTE incidence varied from 35.2 per 1000 deliveries based on 2018 ASH criteria to 2.5 per 1000 in 2015 RCOG criteria. In a large cohort of cesarean deliveries in the United States, application of different risk stratification guidelines identified widely different proportions at risk of VTE following delivery, with implications for being categorized as having elevated risk.

Abstract
Pregnant women with obesity are at increased risk of a multitude of complications of pregnancy and adverse perinatal outcomes. The risk of some of these complications, such as neural tube defects or preeclampsia, may be mitigated by some medications. Other complications, such as diabetes, venous thromboembolism, and infections, require treatment with medications. Given the changes in pharmacokinetics and pharmacodynamics during pregnancy, which is further enhanced by obesity, the optimal medication and its dose is often researched. This chapter further explores the different complications and common medications that women with obesity are likely to require.

Abstract
Even though venous thromboembolism is a leading cause of maternal mortality in high-income countries, there are limited high-quality data to assist clinicians with the management of pulmonary embolism in this patient population. Diagnosis, prevention, and treatment of pregnancy-associated pulmonary embolism are complicated by the need to consider fetal, as well as maternal, well-being. Recent studies suggest that clinical prediction rules and D-dimer testing can reduce the need for diagnostic imaging in a subset of patients. Low-molecular-weight heparin is the preferred anticoagulant for both prophylaxis and treatment in this setting. Direct oral anticoagulants are contraindicated during pregnancy and in breastfeeding women. Thrombolysis or embolectomy should be considered for pregnant women with pulmonary embolism complicated by hemodynamic instability. Treatment of pregnancy-associated pulmonary embolism should be continued for at least 3 months, including 6 weeks postpartum. Management of anticoagulants at the time of delivery should involve a multidisciplinary individualized approach that uses shared decision making to take patient and caregiver values and preferences into account.

Abstract
BACKGROUND Guidelines for postpartum thromboprophylaxis are mostly expert based. Acceptable postpartum venous thromboembolism (VTE) risk thresholds to justify the use of thromboprophylaxis are ill defined. OBJECTIVE To compare the proportion of postpartum women with recommended thromboprophylaxis according to the Royal College of Obstetricians and Gynecologists (RCOG), American College of Obstetricians and Gynecologists (ACOG), and American College of Chest Physicians (ACCP) guidelines, and to estimate their threshold of risk of VTE. METHODS We collected maternal, obstetrical, and fetal characteristics among all women who delivered at the Geneva University Hospitals in January 2019 through medical chart review. We determined for each woman the recommended strategy of thromboprophylaxis according to each guideline. We indirectly estimated individual absolute VTE risks using a validated risk prediction model (Sultan). RESULTS Among 344 women (mean age 32.2 years), with 23.3% of cesarean deliveries (CD), the RCOG guideline categorized 40.1% of all deliveries, 25.4% of vaginal deliveries (VD), and 88.8% of CD as requiring thromboprophylaxis. The ACOG and ACCP guidelines, which focus on CD, categorized fewer women as high risk (35.0% and 40.0% of CD, respectively). The mean estimated risk of VTE was 0.07% in all participants, 0.12% in those with recommended thromboprophylaxis according to the RCOG, and 0.20% among women after CD with recommended thromboprophylaxis by the ACOG and ACCP guidelines. CONCLUSIONS Our data highlight important variations in the proportion of thromboprophylaxis recommendation between guidelines. Risk thresholds to recommend the use of heparin appear very low, and may correlate with a high, and perhaps undesirable, number needed to treat to prevent VTE events.

Abstract
Antiphospholipid syndrome (APS), which is characterized by the presence of antiphospholipid antibodies (aPL), is associated with increased risk of thrombosis and obstetric complications, including preterm delivery and recurrent pregnancy losses. APS shows diverse clinical manifestations and the risk of complications varies among clinical subtypes. Although these patients are usually treated with aspirin and anticoagulants, the optimal treatment in various clinical settings is unclear, as the risk of complications vary among clinical subtypes and the management strategy depends on whether the patient is pregnant or not. Also, there are unmet needs for the evidence-based, pregnancy-related treatment of asymptomatic women positive for aPL. This review focuses on the management of positive aPL or APS in pregnant and postpartum women, and in women attempting to become pregnant. For asymptomatic aPL positive women, no treatment, low dose aspirin (LDA) or LDA plus anticoagulants can be considered during antepartum and postpartum. In obstetric APS patients, preconceptional LDA is recommended. LDA plus low molecular weight heparin is administered after confirmation of pregnancy. Vascular APS patients should take frequent pregnancy test and receive heparin instead of warfarin after confirmation of pregnancy. During pregnancy, heparin plus LDA is recommended. Warfarin can be restarted 4 to 6 hours after vaginal delivery and 6 to 12 hours after cesarean delivery. Most importantly, a tailored approach and patient-oriented treatment are mandatory.
