RESUMEN
Importance: Diabetes mellitus is one of the most common complications in pregnancy with adverse maternal and neonatal risks proportional to the degree of suboptimal glycemic control, which is not well defined. Literature guiding providers in identifying and managing patients at highest risk of complications from diabetes is lacking. Objective: This article reviews the definition, epidemiology, and pathophysiology of suboptimal control of diabetes in pregnancy, including "diabetic fetopathy"; explores proposed methods of risk stratification for patients with diabetes; outlines existing antepartum management and delivery timing guidelines; and guides direction for future research. Evidence Acquisition: Original research articles, review articles, and professional society guidelines on diabetes management in pregnancy were reviewed. Results: The reviewed available studies demonstrate worsening maternal and neonatal outcomes associated with suboptimal control; however, the definition of suboptimal based on parameters followed in pregnancy such as blood glucose, hemoglobin A1c, and fetal growth varied from study to study. Studies demonstrating specific associations of adverse outcomes with defined suboptimal control were reviewed and synthesized. Professional society recommendations were also reviewed to summarize current guidelines on antepartum management and delivery planning with respect to diabetes in pregnancy. Conclusions: The literature heterogeneously characterizes suboptimal glucose control and complications related to this during pregnancy in individuals with diabetes. Further research into antepartum management and delivery timing for patients with varying levels of glycemic control and at highest risk for diabetic complications is still needed.

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.

OBJECTIVE: The COVID pandemic has been associated with varied effects on preterm birth (PTB). We sought to compare rates of PTB during the pre- and post vaccination COVID periods with pre-pandemic PTB rates, stratified by race and ethnicity. STUDY DESIGN: Retrospective cohort comparing all deliveries over 20 weeks at a single tertiary center during "early" (March 2020-June 2020) versus "late" COVID (March 2021-June 2021), and "late" COVID versus pre-COVID (March to June 2014-2019). PTBs <37, <34, and <28 weeks were compared and stratified by race/ethnicity. RESULTS: A total of 16,483 deliveries occurred including 2,068 "early" COVID, 2,115 "late" COVID, and 12,300 pre-COVID. The PTB rate during "late" COVID was lower compared to "early" COVID (12.1 vs. 14.6%, p = 0.02). Rate of PTB <34 was also lower during "late" COVID (4.4 vs. 5.7%, p = 0.05). PTB <28 did not differ. When controlling for prior PTB, "late" COVID remained associated with a decreased risk of PTB compared to "early" COVID, adjusted odds ratio (aOR) of 0.82 (95% confidence interval [CI]: 0.68, 0.98). Although there was no difference in PTB among Hispanic individuals when comparing "late" COVID versus pre-COVID, when further subdivided, a small number of Hispanic Puerto Rican individuals had higher odds of PTB < 37 during "late" COVID versus pre-COVID (aOR = 4.29 [95% CI: 1.12, 16.4]). Additionally, White individuals had reduced odds of PTB <37 (aOR = 0.80 [95% CI: 0.65, 0.98]) during "late" COVID versus pre-COVID while the PTB rate was unchanged when comparing "late" COVID versus pre-COVID in all other racial and ethnic groups. CONCLUSION: During 2021, PTB rates decreased from rates observed in 2020 at the height of COVID restrictions. Among White birthing individuals, PTB decreased in 2021 compared to pre-COVID rates. This decrease was not observed in Black and Hispanic birthing individuals. These data highlight the continued racially disparate impact of the COVID-19 pandemic on PTB rates. KEY POINTS: · The COVID-19 pandemic has been associated with varied effects on the preterm birth (PTB) rate.. · PTB rates decreased in "late" COVID compared to "early" COVID.. · When stratified, PTB decreased among white individuals, but not in Black or Hispanic individuals..
RESUMEN
As many as 1 in 3 patients with gestational diabetes mellitus have impaired glucose metabolism when screened postpartum. These patients have a 40% to 70% lifetime risk of progression to type 2 diabetes mellitus, but progression can be delayed or prevented by lifestyle interventions or medication. The American College of Obstetricians and Gynecologists and the American Diabetes Association recommend a glucose tolerance test at 4 to 12 weeks postpartum for all patients with gestational diabetes mellitus. Despite these recommendations, postpartum screening rates are typically <50%, representing a major healthcare "quality gap." The Society for Maternal-Fetal Medicine proposes a uniform metric that identifies the percentage of persons with gestational diabetes mellitus who completed a 75-g, 2-hour glucose tolerance test within 12 weeks after delivery. The metric is designed to be measured using diagnosis and procedure codes in payor claims data. Barriers to screening are discussed. Possible uses of the metric for quality improvement projects are outlined. Increasing the rate of postpartum diabetes screening should facilitate timely referral to implement lifestyle modifications, medication, and long-term follow-up. Use of the metric in financial incentive programs is discouraged at this time.

OBJECTIVE: Penicillin allergy is the most commonly reported drug allergy in the United States; however, less than 10% of individuals labeled with a penicillin allergy are truly allergic. A reported penicillin allergy in pregnancy is associated with adverse maternal and perinatal outcomes. Despite recommendations for penicillin allergy testing in pregnancy, limited literature regarding obstetric providers' comfort and knowledge in addressing penicillin allergy and referral patterns exists. The objective of this study is to survey obstetric providers to assess their clinical practice patterns and baseline penicillin allergy knowledge, identify potential knowledge gaps in the management of pregnant patients with reported penicillin allergy, and measure the impact of an educational intervention on provider knowledge and practice patterns. STUDY DESIGN: An anonymous, electronic 23-question survey administered to all obstetric providers at a single academic medical center assessed obstetric provider characteristics, self-reported antibiotic practice patterns, and antibiotic allergy knowledge before (June 19, 2020) and after (September 16, 2020) a penicillin allergy educational intervention, which consisted of multiple small-group educational sessions and a culminating departmental educational session. Discrete knowledge comparison by provider type and experience level of pre- and postintervention was performed using chi-square tests. RESULTS: Of 277 obstetric providers invited, 124 (45%) responded preintervention and 62 (22%) postintervention. In total, 27% correctly identified the percentage of patients labeled penicillin allergic who would tolerate penicillins, 45% identified cephalosporin cross-reactivity, 59% understood penicillin allergies can wane, and 54% identified penicillin skin testing (PST) as a valid allergy verification tool. Among 48 respondents who attended educational sessions and responded postintervention, their knowledge of penicillin allergy waning (79% preeducation vs. 98% posteducation, p < 0.01) and PST as a valid tool for penicillin allergy verification (50% preeducation vs. 83% posteducation, p < 0.01) improved. CONCLUSION: Knowledge gaps related to penicillin allergy exist among obstetric providers. Educational initiatives may improve provider knowledge, help in the identification of patients requiring penicillin allergy evaluation, and reduce referral barriers. KEY POINTS: · Obstetric providers lack adequate knowledge of penicillin allergy.. · Educational interventions can improve discrete knowledge.. · Limited knowledge is a barrier to allergy referral for penicillin allergy delabeling..
