RESUMO
BACKGROUND: Intrapartum glucose management is critical to reducing neonatal hypoglycemia shortly after birth. Although it is known that insulin is required for all pregnant individuals with type 1 diabetes mellitus, the optimal mode of intrapartum glycemic control is not known. OBJECTIVE: This study aimed to compare the effect of intrapartum use of continuous subcutaneous insulin infusion with that of intravenous insulin infusion for glucose management among pregnant individuals with type 1 diabetes mellitus on neonatal blood glucose levels. STUDY DESIGN: This was a randomized controlled trial of pregnant participants with type 1 diabetes mellitus. After written informed consent, participants were randomly allocated to 1 of 2 intrapartum insulin administration strategies: continuation of their continuous subcutaneous insulin infusion or intravenous insulin infusion. The primary outcome was the first neonatal blood glucose level. RESULTS: Between March 2021 and April 2023, 76 participants were approached, and 70 participants were randomized (35 participants in the intravenous insulin infusion group and 35 participants in the continuous subcutaneous insulin infusion group). The groups were similar in terms of age, race/ethnicity, pregravid body mass index, nulliparity, and gestational age at delivery. There was no statistically significant difference in the first neonatal glucose measurement between the 2 groups (50.1±23.4 vs 49.2±22.6; P=.86). In addition, there were no statistically significant differences in any secondary neonatal outcomes. Approximately 57.1% of neonates in the continuous subcutaneous insulin infusion group required either oral, intravenous, or both treatments for hypoglycemia, whereas 51.4% of neonates in the intravenous infusion group required treatment. In both groups, 28.6% of neonates required intravenous treatment for hypoglycemia. CONCLUSION: Pregnant individuals with type 1 diabetes mellitus using either intravenous insulin infusion or continuation of their continuous subcutaneous insulin infusion for intrapartum insulin administration had no difference in the primary outcome of neonatal hypoglycemia. Patients should be given the option of both glycemic management strategies intrapartum.

As intrapartum fevers are not always infectious in origin, determining whether antibiotics are indicated is challenging. We previously sought to create a point-of-care calculator using clinical data available at the time of an intrapartum fever to identify the subset of women who require antibiotic treatment to avoid maternal and neonatal morbidity. Despite the use of a comprehensive dataset from our institutions, we were unable to propose a valid and highly predictive model. In this commentary, we discuss why our model failed, as well as future research directions to identify and treat true intraamniotic infection. Developing a risk-stratification model is paramount to minimizing maternal and neonatal exposure to unnecessary antibiotics while allowing for early identification of women and babies at risk for infectious morbidity. KEY POINTS: · Determining whether antibiotics are indicated in intrapartum fever is challenging.. · Developing a risk-stratification model for febrile laboring women is critical to decreasing harm.. · A point-of-care calculator based on clinical and biomarker data is the necessary approach..

This study sought to compare test characteristics of hemoglobin A1c, oral glucose tolerance test and fasting plasma glucose for the development of gestational diabetes among women with prediabetes. Diabetes outcomes were compared by screening test used for prediabetes diagnosis among a retrospective cohort of pregnant patients between 2017-2021. During the study, 8132 patients received diabetes screening and 14.0% met criteria for prediabetes. By screening test, 75.1% were screened with hemoglobin A1c, 10.0% with fasting plasma glucose and 14.9% with a 75-g oral glucose tolerance test. Hemoglobin A1c had the highest positive predictive value (67.2%). Use of hemoglobin A1c was significantly more likely to identify women with GDM than oral glucose tolerance test (aOR 3.94, 95% CI 2.30-6.73). In this study cohort, hemoglobin A1c was able to identify patients that were more likely to develop GDM in an at-risk population.IMPACT STATEMENTWhat is already known on this subject? Prediabetes is becoming more common in the general population; however little is known about prediabetes in pregnancy. Women with prediabetes in pregnancy appear to be at increased risk of developing gestational diabetes mellitus, however there is minimal information about various screening tests performance in pregnancy for detection of prediabetes and subsequent gestational diabetes.What do the results of this study add? The results of this study compare three commonly used screening tests for screening for diabetes. When identifying women with prediabetes, they are at increased risk for developing gestational diabetes mellitus if identified by hemoglobin A1c.What are the implications of these findings for clinical practice and/or further research? The clinical implication of this study is that women can be screened with hemoglobin A1c in early pregnancy for both overt diabetes, but also may be identified as high risk with prediabetes. Among women with prediabetes by hemoglobin A1c, they remain at high risk for developing gestational diabetes mellitus.

OBJECTIVE: The objective of this study was to identify clinical characteristics of patients with hypertensive disorders of pregnancy associated with requiring multiple anti-hypertensive medications to optimize blood pressure in the postpartum setting. STUDY DESIGN: We performed a retrospective cohort study of all women who had a diagnosis of hypertensive disorders of pregnancy who delivered at a single institution between October 1, 2017 and May 1, 2021. Demographics and clinical characteristics including category of anti-hypertensive medication and number of medications were collected. Models were adjusted for race. RESULTS: A total of 1,708 women were identified for inclusion. Of this cohort, 64.9 % did not require any anti-hypertensive medications, while 24.8 % used one medication and 10.2 % required two or more medications. When comparing women by the number of medications that were required, their demographics were similar except for race (p < 0.001). Women taking two or more medications were most prescribed a beta blocker (94.9 %) followed by a calcium channel blocker (88.6 %). Women with a history of chronic hypertension had the highest risk of requiring two or more medications for blood pressure control (adjusted RR 11.19, 95 % CI 2.63-47.60). Chronic kidney disease also significantly increased the risk of requiring two or more medications (adjusted RR 3.09, 95 % CI 1.24-7.69). CONCLUSION: Women with chronic hypertension and chronic kidney disease are at increased risk for requiring multiple anti-hypertensive medications in the postpartum setting. We recommend frequent postpartum visits, either in person or implementing telemedicine platforms to optimize blood pressure control for this high-risk cohort.

BACKGROUND: Cardiac disease is a leading cause of maternal morbidity and mortality in the United States, and an increasing number of patients with known cardiac disease are reaching childbearing age. Although guidelines indicate that cesarean deliveries should be reserved for obstetrical indications, rates of cesarean delivery among obstetrical patients with cardiovascular disease are higher than those of the general population. OBJECTIVE: This study aimed to evaluate mode of delivery and perinatal outcomes among patients with low-risk and moderate to high-risk cardiac disease as defined by the modified World Health Organization classification of maternal cardiovascular risk. STUDY DESIGN: We performed a retrospective cohort study of obstetrical patients with known cardiac disease, as defined by the modified World Health Organization cardiovascular classification categories in pregnancy, who underwent a perinatal transthoracic echocardiogram at a single academic medical center between October 1, 2017 and May 1, 2022. Demographics, clinical characteristics, and perinatal outcomes were collected. Comparisons were made between patients with low- (modified World Health Organization Class I) and moderate to high-risk (modified World Health Organization Class II-IV) cardiac disease using chi-square, Fisher exact, or Student t-tests. Cohen d tests were used to estimate the effect size between group means. Logistic regression models were used to evaluate the odds of vaginal and cesarean delivery in low- and moderate to high-risk groups. RESULTS: A total of 108 participants were eligible for inclusion, with 41 participants in the low-risk cardiac group and 67 in the moderate to high-risk group. Participants had a mean age of 32.1 (±5.5) years at the time of delivery and a mean pregravid body mass index of 29.9 (±7.8) kg/m2. Chronic hypertension (13.9%) and a history of hypertensive disorder of pregnancy (14.9%) were the most common comorbid medical conditions. In total, 17.1% of the sample had a history of a cardiac event (eg, arrhythmia, heart failure, myocardial infarction). Rates of vaginal and cesarean deliveries were similar between the low- and moderate to high-risk cardiac groups. Patients in the moderate to high-risk cardiac group were more likely to be admitted to the intensive care unit during pregnancy (odds ratio, 7.8; P<.05) and experience severe maternal morbidity compared with patients in the low-risk cardiac group (P<.01). Mode of delivery was not associated with severe maternal morbidity in the higher-risk cardiac group (odds ratio, 3.2; P=.12). In addition, infants of mothers with higher-risk disease were more likely to be admitted to the neonatal intensive care unit (odds ratio, 3.6; P=.06) and have longer neonatal intensive care unit stays (P=.005). CONCLUSION: There was no difference in mode of delivery by modified World Health Organization cardiac classification, and mode of delivery was not associated with risk of severe maternal morbidity. Despite the overall increased risk of morbidity in the higher-risk group, vaginal delivery should be considered as an option for certain patients with well-compensated cardiac disease. However, larger studies are needed to confirm these findings.

BACKGROUND: Stillbirth impacts 1% of all pregnancies in the USA with the underlying cause often remaining unknown. The objective of this study was to identify if prenatal aneuploidy screening impacted patient agreement to stillbirth evaluation. METHODS: We performed a retrospective cohort study of patients with a singleton stillbirth after 20 weeks of gestation between October 2017 and December 2021. Demographics and stillbirth evaluation were collected for all patients. Multivariable logistic regression was performed adjusting for variables that were significant in univariate analysis. RESULTS: A total of 81 persons experienced stillbirth during the study period. Approximately 59.3% of patients had prenatal aneuploidy screening: 39.5% integrated screening, 37.5% non-invasive prenatal testing (NIPT), and 22.9% quad screen. Prenatal genetic screening did not significantly impact patient agreement to placental pathology, serum laboratory evaluation, or fetal autopsy. Patients with NIPT were less likely to have genetic testing sent at the time of stillbirth compared to those with another aneuploidy screening (aOR 0.27, 95% CI 0.07-0.99). CONCLUSIONS: Prenatal aneuploidy screening was not associated with patient acceptance of stillbirth evaluation. However, patients with NIPT were less likely to pursue further genetic testing during stillbirth evaluation, so further education regarding the benefit of karyotype and microarray should be included in patient counseling.
RESUMO
Objective: The aim of this study was to characterize current diabetes screening practices in the first trimester of pregnancy in the United States, evaluate patient characteristics and risk factors associated with early diabetes screening, and compare perinatal outcomes by early diabetes screening. Methods: This was a retrospective cohort study of US medical claims data of persons diagnosed with a viable intrauterine pregnancy and who presented for care with private insurance before 14 weeks of gestation, without pre-existing pregestational diabetes, from the IBM MarketScan® database for the period January 1, 2016, to December 31, 2018. Univariate and multivariate analyses were used to evaluate perinatal outcomes. Results: A total of 400,588 pregnancies were identified as eligible for inclusion, with 18.0% of persons receiving early screening for diabetes. Of those with laboratory order claims, 53.1% underwent hemoglobin A1c testing, 30.0% underwent fasting glucose testing, and 16.9% underwent oral glucose tolerance testing. Compared with those who did not undergo early diabetes screening, those who did were more likely to be older; obese; having a history of gestational diabetes, chronic hypertension, polycystic ovarian syndrome, or hyperlipidemia; and having a family history of diabetes. In adjusted logistic regression, history of gestational diabetes (adjusted odds ratio 3.99; 95% confidence interval 3.73-4.26) had the strongest association with early diabetes screening. Adverse perinatal outcomes, including a higher rate of cesarean delivery, preterm delivery, preeclampsia, and gestational diabetes, occurred more frequently among women who underwent early diabetes screening. Conclusions: First-trimester early diabetes screening was mostly commonly performed by hemoglobin A1c evaluation, and persons who underwent early diabetes screening were more likely to experience adverse perinatal outcomes.

Background: Heart-healthy diets are important in the prevention and treatment of hypertension (HTN), including among pregnant women. Yet, the barriers, facilitators, and beliefs/preferences regarding healthy eating are not well described in this population. Objective: To identify barriers and facilitators to healthy diet, examine the prevalence of food insecurity, and determine interest in specific healthy diet interventions. Methods: Pregnant women, aged 18-50 years (N = 38), diagnosed with HTN, hypertensive disorders in pregnancy (HDP), or risk factors for HDP, were recruited from a large academic medical center in central Massachusetts between June 2020 and June 2022. Participants completed an electronic survey using a 5-point Likert scale (strongly disagree to strongly agree). Results: The mean age of participants was 31.6 years (SD 5.5) and 35.1% identified as Hispanic. Finances and time were major barriers to a healthy diet, reported by 42.1% and 28.9% of participants, respectively. Participants reported that their partners and families were supportive of healthy eating and preparing meals at home, though 30.0% of those with children considered their children's diet a barrier to preparing healthy meals. Additionally, 40.5% of the sample were considered food insecure. Everyone agreed that healthy diet was important for maternal and fetal health, and the most popular interventions were healthy ingredient grocery deliveries (89.4%) and meal deliveries (84.2%). Conclusion: Time and cost emerged as major challenges to healthy eating in these pregnant women. Such barriers, facilitators, and preferences can aid in intervention development and policy-level changes to mitigate obstacles to healthy eating in this vulnerable patient population.
RESUMO
Mitral valve prolapse (MVP) is the most common valvular heart disease in women of reproductive age. Whether MVP increases the likelihood of adverse outcomes in pregnancy is unknown. The study objective was to examine the cardiac and obstetric outcomes associated with MVP in pregnant women. This retrospective cohort study, using the Healthcare Cost and Utilization Project National Readmission Sample database between 2010 and 2017, identified all pregnant women with MVP using the International Classification of Disease, Ninth and Tenth Revisions codes. The maternal cardiac and obstetric outcomes in pregnant women diagnosed with MVP were compared with women without MVP using multivariable logistic and Cox proportional hazard regression models adjusted for baseline demographic characteristics. There were 23,000 pregnancy admissions with MVP with an overall incidence of 16.9 cases per 10,000 pregnancy admissions. Pregnant women with MVP were more likely to die during pregnancy (adjusted hazard ratio 5.13, 95% confidence interval [CI] 1.09 to 24.16), develop cardiac arrest (adjusted odds ratio [aOR] 4.44, 95% CI 1.04 to 18.89), arrhythmia (aOR 10.96, 95% CI 9.17 to 13.12), stroke (aOR 6.90, 95% CI 1.26 to 37.58), heart failure (aOR 5.81, 95% CI 3.84 to 8.79), or suffer a coronary artery dissection (aOR 25.22, 95% CI 3.42 to 186.07) compared with women without MVP. Pregnancies with MVP were also associated with increased risks of preterm delivery (aOR 1.21, 95% CI 1.02 to 1.44) and preeclampsia/hemolysis, elevated liver enzymes, and low platelets syndrome (aOR 1.22, 95% CI 1.05 to 1.41). In conclusion, MVP in pregnancy is associated with adverse maternal cardiac outcomes and higher obstetric risks.

OBJECTIVE: To examine the microbiology and associated antibiotic resistance patterns among febrile peripartum women with positive blood cultures. METHODS: We conducted a retrospective cohort study in which we reviewed all bacteremia cases between 2009 and 2016 that occurred between 7 days before and 30 days after delivery. Institutional guidelines include obtaining blood cultures and promptly initiating intravenous antibiotics for all obstetric patients with fever of 100.4°F or higher. We describe antibiotic resistance patterns for the most frequently isolated organisms and perform univariate analyses regarding maternal and neonatal outcomes based on type of bacteremia. RESULTS: Among 56,835 deliveries, 3,797 (6.7%) obstetric patients had blood cultures drawn and 120 (3.2%) had documented bacteremia. The most commonly cultured organisms were Escherichia coli (17.5%, n=21), Bacteroides species (10.8%, n=13), Enterococcus species (10.8%, n=13), group B streptococci (10.8%, n=13), and group A streptococci (5.0%, n=6). E coli had high rates of resistance to ampicillin (n=17, 81.0%) and extended spectrum beta lactams (n=10, 47.6%). Gram-positive bacteremia was noted in 65/120 patients (54.2%), gram-negative bacteremia in 39/120 (32.5%), and anaerobic bacteremia in 16/120 (13.3%) (P=.02). Neonatal bacteremia was identified in 8/120 cases (6.7%), of which 7/8 (87.5%) were attributable to gram-negative bacteria and 1/8 (12.5%) were attributable to gram-positive bacteremia (P=.004). There were no differences in neonatal death or maternal intensive care unit admission. CONCLUSION: Peripartum bacteremia is uncommon, with the most frequently isolated organism being E coli. The evolution of antibiotic resistance patterns in E coli at our institution may be of clinical significance in determining antibiotic choice for peripartum fever.

BACKGROUND: Menorrhagia is a common gynecologic complaint among adolescents, which rarely is secondary to malignancy. Burkitt lymphoma can mimic gynecologic malignancy, however it is rarely seen in adolescents. Burkitt lymphoma of the gynecologic tract requires early diagnosis and intervention for optimal outcomes. CASE: We report a case of a 15-year-old adolescent who had multiple admissions for menorrhagia that was thought to be secondary to anovulatory bleeding until pelvic ultrasound revealed a large 8-cm vaginal/cervical mass. Histologic examination of the biopsy specimen revealed Burkitt lymphoma, which was treated with chemotherapy leading to resolution of her menorrhagia. SUMMARY AND CONCLUSION: Burkitt lymphoma presenting as a vaginal/cervical mass is exceedingly rare, especially in the adolescent patient. Burkitt lymphoma is generally highly responsive to chemotherapy, and symptoms rapidly improve after initiation of treatment.

OBJECTIVE: Identify risk factors for poor perineal outcome after operative vaginal delivery. STUDY DESIGN: A retrospective cohort study was performed including operative vaginal deliveries during 2015 through 2016. RESULTS: Of 529 operative vaginal deliveries, 79 (14.9%) had higher order perineal lacerations and 14 (2.7%) had a wound breakdown. The only significant risk factor for higher order lacerations was chorioamnionitis (aOR 2.2; 95% CI 1.09-4.44). Risk factors for perineal wound breakdown included episiotomy (5.2 vs. 1.2%; p < 0.01), type of operative delivery (5.5% after forceps vs. 1.4% after vacuum; p < 0.01) and postpartum narcotic use. Overall, 9.3% of those using narcotics subsequently had a perineal breakdown as compared to 0.7% (p < 0.01). Narcotic use postpartum remained strongly associated in multivariable logistic regression (aOR 21.29; 95% CI 5.43-83.47). Patients with forceps deliveries, episiotomy, and narcotic use had a 38% risk of breakdown. CONCLUSION: Women at highest risk of perineal wound breakdown benefit from close follow-up.

STUDY OBJECTIVE: To determine whether complications during pregnancy or at delivery influence postpartum contraception choices and rapid repeat pregnancy rates in adolescent women. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This retrospective cohort study included 321 adolescents delivering at UMASS Memorial Healthcare. Complications during pregnancy and delivery along with subsequent contraception use were investigated. Postpartum contraception choice (long-acting reversible contraception [LARC] vs non-LARC) at either delivery, hospitalization discharge, or at postpartum outpatient appointment, and rapid repeat pregnancy rate (pregnancy confirmed within 12 months of index delivery), were analyzed according to pregnancy complications. Comparisons were made with χ2 and Fisher exact tests for categorical variables, and with Wilcoxon rank sum test for continuous variables. RESULTS: Of the study population, 27.7% (n = 89/321) used LARC in the postpartum period. The LARC and non-LARC patient populations differed significantly regarding history of abortion (P = .029), with no differences in obstetric complications between the groups. Of the population, 16.6% (n = 53/320) became pregnant again within 1 year of their index delivery. Those with a rapid repeat pregnancy had significantly increased gravidity (P = .002), parity (P = .003), number of previous spontaneous or therapeutic abortions (P = .026); they were also more like to have nonlive birth as a complication (P = .028), compared with those without repeat pregnancy. No other obstetrical complications were statistically significantly different between the compared groups. CONCLUSION: Obstetrical complications seem to have little effect on postpartum contraception choice or repeat pregnancy rate with the notable exception of nonlive birth being associated with rapid repeat pregnancy.
