RESUMEN
Increasing rates of thromboembolic complications have required increasing use of anticoagulant and antiplatelet agents during and after pregnancy. Furthermore, thromboembolism is both a cause and a complication of severe maternal morbidity requiring intensive care. As a consequence, almost all patients admitted to intensive care units receive an anticoagulant or an antiplatelet agent (or both) for either treatment or prevention of thromboembolism. In this review, we summarize commonly used anticoagulants and antiplatelet agents and outline the potential role of newly developed (novel) antithrombotic agents for pregnant and postpartum patients.

OBJECTIVE: The use of extracorporeal membrane oxygenation (ECMO) therapy has increased in the adult population. Studies from the H1N1 influenza pandemic suggest that ECMO deployment in pregnancy is associated with favorable outcomes. With increasing numbers of pregnant women affected by COVID-19 (coronavirus disease 2019) and potentially requiring this life-saving therapy, we sought to compare comorbidities, costs, and outcomes between pregnancy- and nonpregnancy-associated ECMO therapy among reproductive-aged female patients. STUDY DESIGN: We used the 2013 to 2019 National Readmissions Database. Diagnosis and procedural coding were used to identify ECMO deployment, potential indications, comorbid conditions, and pregnancy outcomes. The primary outcome was in-hospital mortality during the patient's initial ECMO stay. Secondary outcomes included length of stay and hospital charges/costs, occurrence of thromboembolic or bleeding complications during ECMO hospitalization, and mortality and readmissions up to 330 days following ECMO stay. Univariate and multivariate regression models were used to model the associations between pregnancy status and outcomes. RESULTS: The sample included 324 pregnancy-associated hospitalizations and 3,805 nonpregnancy-associated hospitalizations, corresponding to national estimates of 665 and 7,653 over the study period, respectively. Pregnancy-associated ECMO had lower incidence of in-hospital death (adjusted odds ratio [aOR]: 0.56, 95% confidence interval [CI]: 0.41-0.75) and bleeding complications (aOR: 0.67, 95% CI: 0.49-0.93). Length of stay was significantly shorter (adjusted rate ratio (aRR): 0.86, 95% CI: 0.77-0.96) and total hospital costs were less (aRR: 0.83, 95% CI: 0.75-0.93). Differences in the incidence of thromboembolic events (aOR: 1.04, 95% CI: 0.78-1.38) were not statistically significant. CONCLUSION: Pregnancy-associated ECMO therapy had lower incidence of in-hospital death, bleeding complications, total inpatient cost, and length of stay when compared with nonpregnancy-associated ECMO therapy without increased thromboembolic complications. Pregnancy-associated ECMO therapy should be offered to eligible patients. KEY POINTS: · Pregnancy-related ECMO use was compared with nonpregnant use.. · Outcomes were equal or favored pregnancy-related deployment.. · These data may be useful when considering ECMO use in pregnancy..
RESUMEN
OBJECTIVE: The Laparoscopic Approach to Cervical Cancer (LACC) trial found that minimally invasive radical hysterectomy compared to open radical hysterectomy compromised oncologic outcomes and was associated with worse progression-free survival (PFS) and overall survival (OS) in early-stage cervical carcinoma. We sought to assess oncologic outcomes at multiple centers between minimally invasive (MIS) radical hysterectomy and OPEN radical hysterectomy. METHODS: This is a multi-institutional, retrospective cohort study of patients with 2009 FIGO stage IA1 (with lymphovascular space invasion) to IB1 cervical carcinoma from 1/2007-12/2016. Patients who underwent preoperative therapy were excluded. Squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinomas were included. Appropriate statistical tests were used. RESULTS: We identified 1093 cases for analysis-715 MIS (558 robotic [78%]) and 378. OPEN procedures. The OPEN cohort had more patients with tumors >2 cm, residual disease in the hysterectomy specimen, and more likely to have had adjuvant therapy. Median follow-up for the MIS and OPEN cohorts were 38.5 months (range, 0.03-149.51) and 54.98 months (range, 0.03-145.20), respectively. Three-year PFS rates were 87.9% (95% CI: 84.9-90.4%) and 89% (95% CI: 84.9-92%), respectively (P = 0.6). On multivariate analysis, the adjusted HR for recurrence/death was 0.70 (95% CI: 0.47-1.03; P = 0.07). Three-year OS rates were 95.8% (95% CI: 93.6-97.2%) and 96.6% (95% CI: 93.8-98.2%), respectively (P = 0.8). On multivariate analysis, the adjusted HR for death was 0.81 (95% CI: 0.43-1.52; P = 0.5). CONCLUSION: This multi-institutional analysis showed that an MIS compared to OPEN radical hysterectomy for cervical cancer did not appear to compromise oncologic outcomes, with similar PFS and OS.

ABSTRACT: Hemolytic disease of fetus and newborn (HDFN) is a life-threatening disease mediated by maternal alloimmunization to red blood cell (RBC) antigens. Studies of maternal alloimmunization prevalence in the United States lack national data. This study describes prevalence and trends in alloimmunization in pregnancy in the United States. RBC antibodies (abs) were identified in a large, nationwide, commercial laboratory database from 2010 through 2021. The cohort comprised pregnancies for which the year of laboratory collection and patient's state of residence were available. Data were normalized based on US Centers for Disease Control and Prevention estimates of live births and weighted by year and US Census Division. Cochrane-Armitage tests assessed temporal trends of alloimmunization. Of 9 876 196 pregnancies, 147 262 (1.5%) screened positive for RBC abs, corresponding to an estimated prevalence of 1518 of 100 000 pregnancies. Of identified RBC abs, anti-D comprised 64.1% pregnancies (586/100 000). Prevalence of other high-risk RBC abs for HDFN included anti-K (68/100 000) and anti-c (29/100 000). Incidence of all 3 high-risk abs increased from 2010 to 2021 (all P < .001). Among almost 10 million pregnancies in the United States, comprising an estimated 14.4% of all pregnancies, 1.5% screened positive for RBC abs. Almost three-quarters (679/100 000 [74.3%]) of RBC abs identified were high risk for HDFN. Although prevalence of anti-D is difficult to interpret without the ability to distinguish alloimmunization from passive immunity, it remains problematic in HDFN, ranking second only to anti-K in critical titers. Given the sequelae of HDFN, new initiatives are required to reduce the incidence of alloimmunization in patients of reproductive potential.

OBJECTIVE: To systematically review and meta-analyze alloimmunization among recipients of red blood cells (RBCs) matched for ABO blood type and Rhesus D (ABO+D) antigen compared with those also matched for c, E, and Kell (cEK). DATA SOURCES: Four online databases (Medline, Scopus, EMBASE, ClinicalTrials.gov) were searched from March 28, 2023, to April 1, 2024. The search protocol was peer reviewed and published on PROSPERO (CRD42023411620). METHODS OF STUDY SELECTION: Studies reporting alloimmunization as the primary outcome among recipients of RBCs matched for ABO+D or additional cEK matching were included. Patients transfused with unmatched RBCs or a mixture of matching regimens were excluded. Risk of bias was assessed with Cochrane Tool to Assess Risk of Bias in Cohort Studies and Tool for Risk of Bias. Random-effects meta-analysis was used to combine effect estimates. TABULATION, INTEGRATION, AND RESULTS: Ten studies met criteria. Risk of bias was low. Overall, 91,221 patients were transfused, of whom 40,220 (44.1%) received additional cEK-matched RBCs. The overall rate of alloimmunization was 6.2% (95% CI, 2.5-14.9%) for ABO+D-only matching and 1.9% (95% CI, 0.7-5.1%) when cEK was added. Time of follow-up antibody testing ranged from 6 to 18 months after transfusion. Additional cEK match was associated with significantly less alloimmunization compared with standard ABO+D match (odds ratio [OR] 0.37, 95% CI, 0.20-0.69). This association remained when chronically transfused patients were excluded (OR 0.65, 95% CI, 0.54-0.79) and for alloimmunization to c, E, or K antigens only (OR 0.29, 95% CI, 0.18-0.47). CONCLUSION: Additional cEK RBC matching protocols were associated with lower odds of recipient alloimmunization. Given severe sequelae of alloimmunization in pregnancy, routine cEK matching for transfusion in people with pregnancy potential younger than age 50 years in the United States merits consideration.

RESUMEN
BACKGROUND: Venous thromboembolism (VTE) risk is increased independently by both cancer and pregnancy. OBJECTIVES: To estimate VTE risk in the postpartum period among patients delivering with a cancer diagnosis, stratified by cancer type and delivery route. METHODS: We performed a retrospective cohort study utilizing the large, all-payer Nationwide Readmissions Database from October 2015 through December 2020. We identified delivery hospitalizations, cancer diagnoses, and VTE using patient demographics and diagnosis codes. The primary outcome was VTE incidence at 42 and 330 days from delivery admission date, comparing patients with and without cancer diagnoses. A secondary analysis included VTE risk stratified by cancer diagnosis and delivery route. Outcomes were compared using inverse probability-weighted survival curves. RESULTS: The study population included 9 793 503 delivery hospitalizations (weighted estimate, 18 207 346), with a weighted estimate of 10 428 (0.06%) pregnant patients with cancer. Individuals with cancer were older, with higher rates of comorbid conditions, than those without cancer. VTE incidence in individuals with cancer at 42 and 330 days was 1.11% and 2.19%, respectively, vs 0.11% and 0.14%, respectively, in those without cancer. At 330 days, this finding was significant in both unadjusted (relative risk, 15.52; 95% CI, 11.54-19.51) and adjusted (relative risk, 9.68; 95% CI, 7.18-12.18) models. Stratification by cancer type and delivery route demonstrated elevated VTE risk across cancer types, with cesarean delivery conferring a greater risk. CONCLUSION: Cancer in pregnancy confers excess thromboembolic risk extending beyond the immediate postpartum period. Further study is needed to identify optimal VTE prophylactic strategies for this population.

INTRODUCTION: GNAS mutations have been reported in both McCune-Albright syndrome (MAS) and juvenile granulosa cell tumors (JGCT) but have never been reported simultaneously in the same patient. CASE PRESENTATION: A 15-year-old girl developed secondary oligomenorrhea. Laboratory studies revealed suppressed gonadotropin levels with markedly elevated estradiol and inhibin B levels. Pelvic ultrasound showed a 12-cm heterogeneous right adnexal mass; pelvic magnetic resonance imaging to further characterize the mass displayed heterogeneous bilateral femoral bone lesions initially concerning for metastatic disease. Positron emission tomography/computed tomography showed minimal 18F-fluorodeoxyglucose (FDG) uptake in the pelvic mass but unexpectedly revealed FDG uptake throughout the skeleton, concerning for polyostotic fibrous dysplasia in the context of MAS. The adnexal mass was excised and pathology confirmed a JGCT. The patient's affected bone and JGCT tissue revealed the same pathogenic GNAS p.R201C mutation, while her peripheral blood contained wild-type arginine at codon 201. CONCLUSION: This mutation has been previously reported in cases of MAS and JGCT but never simultaneously in the same patient. This demonstration of a GNAS mutation underlying both JGCT and MAS in the same patient raises questions about appropriate surveillance for patients with these conditions.
RESUMEN
OBJECTIVE: To evaluate the effects of eliminating the routine use of oral opioids for postcesarean delivery analgesia on postcesarean opioid consumption. METHODS: At a tertiary care center, we implemented a quality improvement intervention among faculty practice patients undergoing cesarean delivery, which consisted of 1) eliminating routine ordering of oral opioids after cesarean delivery, 2) implementing guidelines for ordering a short course of opioids when deemed necessary, and 3) coupling opioid prescribing at discharge to patterns of opioid use in-hospital combined with shared decision-making. All patients, both before and after the intervention, were administered neuraxial opioids and scheduled acetaminophen and nonsteroidal antiinflammatory medications in the absence of contraindications. The primary outcome was the percentage of women who used any opioids postoperatively in-hospital. Secondary outcomes included the percentage of women discharged with a prescription for opioids, the quantity of opioids used in-hospital, pain scores, satisfaction, opioid-related side effects, and opioid prescriptions ordered in the 6 weeks after delivery. The effects of this intervention were assessed based on a chart review of patient data and a survey of patients in the 12 weeks before and 12 weeks after the intervention. RESULTS: We evaluated the records of 191 postcesarean delivery patients before and 181 after the intervention. Less than half of women used oral opioids in-hospital after the intervention, 82 (45%) compared with 130 (68%) before (P<.001). However, there was no change in pain scores or overall satisfaction with pain relief. Postintervention, only 40% of patients were discharged with prescriptions for opioids compared with 91% of patients before the intervention (P<.001). CONCLUSION: Eliminating routine ordering of oral opioids after cesarean delivery is associated with a significant decrease in opioid consumption while maintaining the same levels of pain control and patient satisfaction. Oral opioids are not needed by a large proportion of women after cesarean delivery.

Diabetes is a common chronic condition in women of reproductive age. Preconception care is crucial to reducing the risk of adverse maternal and fetal outcomes, such as hypertensive disorders, abnormal fetal growth, traumatic delivery and stillbirth, associated with poor glycemic control. Insulin is the preferred medication to optimize glucose control in women with pregestational diabetes. Frequent dose adjustments are needed during pregnancy to achieve glycemic goals, and team-based multidisciplinary care may help. Postpartum care should include lactation support, counseling on contraceptive options, and transition to primary care.
