RESUMO
OBJECTIVE: Nationwide, obstetric clinics modified prenatal care to include telehealth visits in response to the coronavirus disease 2019 (COVID-19) pandemic, enabling the opportunity to investigate its impact on patient outcomes. We hypothesized that use of prenatal telehealth visits would increase the number of prenatal visits, decrease the frequency of urgent triage/emergency department (ED) visits, and improve perinatal outcomes. This study aimed to determine the impact of telehealth on number of obstetric prenatal visits and urgent triage/ED visits amidst the COVID-19 pandemic. STUDY DESIGN: This is a retrospective cohort of patients from a federally qualified health center in central Texas. Patients with a singleton gestation who delivered after 32 weeks were included. Comparison groups were made between those patients who delivered between May 2020 and December 2020 (presumed modified prenatal visit schedule with in-person and telehealth) and those patients delivering between June 2019 and February 2020 (the traditional care model with in-person visits only). Multivariable linear and logistic regression models were used to estimate differences in the number of prenatal visits and unscheduled triage/ED visits. RESULTS: A total of 1,654 patients were identified with 801 (48.4%) patients undergoing modified prenatal care and 853 (51.6%) patients receiving traditional care during the study period. No significant differences were seen in overall prenatal attendance or triage/ED presentations. However, when stratified by parity, multiparous patients undergoing modified prenatal care were less likely to experience an urgent triage/ED presentation (8.7 vs. 12.7%; odds ratio, 1.69; 95% confidence interval, 1.10-2.61). CONCLUSION: When compared with a traditional prenatal visitation cohort prepandemic, patients who received modified telehealth prenatal care during the COVID-19 pandemic had similar prenatal attendance and unscheduled emergency presentations. However, multiparous patients experienced a decreased rate of unscheduled emergency presentations. Supplementing prenatal care with telehealth may provide overall comparable prenatal care delivery. KEY POINTS: · Use of telehealth has the potential to improve prenatal care.. · The COVID-19 pandemic allowed for comparison to traditional prenatal care.. · Multiparous patients had a decreased frequency of ED visits.. · Similar prenatal attendance was seen between both prenatal models..
RESUMO
OBJECTIVE: Periviable premature rupture of membranes (PROM) counseling should describe maternal and neonatal outcomes associated with both immediate delivery and expectant management. Unfortunately, most published data focuses on neonatal outcomes and maternal risk estimates vary widely. We performed a meta-analysis to describe outcomes associated with expectant management compared with immediate delivery of periviable PROM. STUDY DESIGN: We performed a search on PubMed, MEDLINE, Web of Science, PROSPERO, Cochrane library, and ClinicalTrials.gov utilizing a combination of key terms. Published clinical trials and observational cohorts were included if published after 2000. Publications were selected if they included maternal and/or neonatal outcomes for both expectant management and immediate delivery. Gestational age range was limited from 14 to 25 weeks. The primary outcome was maternal sepsis. Secondary outcomes included chorioamnionitis, hemorrhage, laparotomy, and neonatal survival. Pooled risk differences (RDs) were calculated for each outcome using a random-effects model. Publication bias was assessed using funnel plots and Harbord test. RESULTS: A total of 2,550 studies were screened. After removal of duplicates and filtering by abstract, 44 manuscripts were reviewed. A total of five publications met inclusion for analysis: four retrospective and one prospective. Overall, 364 (68.0%) women underwent expectant management and 171 (32.0%) underwent immediate delivery. Maternal sepsis was significantly more frequent in the expectant group (RD, 4%; 95% confidence interval, 2-7%) as was chorioamnionitis (RD: 30%; p < 0.01) and any laparotomy (RD: 28%; p < 0.01). Neonatal survival in the expectant group was 39% compared with 0% in the immediate group (p < 0.01). CONCLUSION: Women who undergo expectant management following periviable rupture of membranes experience significantly increased risks of sepsis, chorioamnionitis, and laparotomy. Overall, 39% of neonates survive to discharge. Knowledge of these risks is critical to counseling patients with this diagnosis. KEY POINTS: · Expectant management associated with 4% increased risk of sepsis.. · Expectant management associated with 30% increased risk of chorioamnionitis.. · A total of 39% of neonates survived to discharge with expectant management..

OBJECTIVE: Following the release of A Randomized Trial of Induction versus Expectant Management (ARRIVE) trial, the induction of labor at 39 weeks has increased in the United States. The risk of uterine rupture and optimal timing of elective induction in those patients with a prior cesarean delivery is not well-described, and they were not included in the original trial. We aimed to determine the risk of uterine rupture in those patients undergoing elective induction of labor with prior cesarean delivery. STUDY DESIGN: This was a retrospective cohort of participants with prior cesarean delivery from 1996 to 2000. Participants were included if they had two or more prior cesareans. Participants were excluded if they had a history of an unknown prior incision, a classical incision, gestational age <39 weeks, any diabetes, chronic hypertension, twin gestation, collagen or vascular disease, or HIV. Those undergoing expectant management were compared with those undergoing elective induction with no medical or obstetrical indications for delivery. Analysis was performed at three gestational age groups: 39 weeks, 40 weeks, and 41 weeks. The primary outcomes were uterine rupture, rates of successful vaginal delivery, and a composite major morbidity risk. Multivariable logistic regression was performed. RESULTS: At 39 weeks, 618 (10.3%) elective inductions were compared with 5,365 (89.7%) undergoing expectant management; uterine rupture occurred more frequently (13 patients [2.1%] vs. 49 patients [0.9%]; adjusted odds ratio [aOR], 2.5; 95% confidence interval, 1.3-4.6) with fewer successful vaginal birth after cesarean [VBAC; 66.8 vs. 75%; aOR, 0.6; 95% confidence interval, 0.5-0.7]. The risk of uterine rupture was similar between groups at 40 weeks (5 patients [0.8%] vs. 21 patients [1.2%]; p = 0.387) and 41 weeks (7 patients [1.4%] vs. 2 patients (0.8%); p = 0.448). CONCLUSION: Patients undergoing elective induction of labor with a prior cesarean scar had an increased risk of uterine rupture when compared with expectant management at 39 weeks, with fewer successful VBAC. KEY POINTS: · TOLAC elective induction at 39 weeks has an increased risk of uterine rupture.. · TOLAC elective induction at 39 weeks has a less successful chance of vaginal delivery.. · Awaiting spontaneous labor in this cohort does not increase the risk of uterine rupture..
RESUMO
OBJECTIVES: To assess physiologic blood pressure (BP) changes throughout pregnancy in patients with mild chronic hypertension (CHTN) who do and do not develop preeclampsia (PEC), compared to patients with normal BP. STUDY DESIGN: Retrospective cohort of singleton gestations with CHTN at a single tertiary center from 2000 to 2014 and a randomly selected cohort of patients without CHTN and normal pregnancy outcomes (NML) in the same time period with BP measurements available <12 weeks gestational age. MAIN OUTCOME MEASURES: The primary outcome was gestational age (GA) at nadir of systolic and diastolic BP. Secondary outcomes included perinatal death, umbilical cord pH, maternal and neonatal length of stay, GA at delivery, and mode of delivery. Quadratic mixed models were used to estimate SBP and DBP throughout gestation. RESULTS: Of 367 pregnancies with CHTN, 268 (73%) had CHTN without PEC and 99 (27%) had CHTN with PEC; 198 NML pregnancies were used as a comparison group. The median GA nadir for patients in the NML, CHTN without PEC, and CHTN with PEC for SBP were 20, 24, and 21, respectively. For DBP, the median GA nadir were 22, 24, and 21 for patients in the NML, CHTN without PEC, and CHTN with PEC cohorts, respectively. Adverse secondary outcomes were more frequent in patients with CHTN who developed PEC. CONCLUSIONS: BP trajectories in pregnancy are different between patients with CHTN with PEC, CHTN without PEC, and patients with normal BP. These findings may be useful in assessing patients' risks for developing preeclampsia during pregnancy.

BACKGROUND: Patients with obesity experience an increased duration of labor with an increased risk for perinatal morbidity. When compared with parturients without obesity, they also experience fewer uterine contractions after administration of misoprostol. It is unclear if the same dose of misoprostol should be used for induction of labor in patients with obesity compared to non-obese patients. Therefore, we sought to investigate if a higher dose of misoprostol for patients with obesity is more effective. OBJECTIVE: This study aimed to determine if 50 µg compared with 25 µg of vaginal misoprostol reduced the time from induction start to delivery among patients with obesity. STUDY DESIGN: We performed a double-blinded, pragmatic randomized controlled trial, between June 1, 2022, and July 17, 2023. Patients with a body mass index ≥30 kg/m2 who underwent labor induction at ≥ 36 weeks' gestation, had a singleton gestation, and a cervical dilation ≤3 cm at admission were included. Patients were excluded if they had a contraindication to vaginal delivery or misoprostol administration. Patients were randomized to 25 or 50 µg of vaginal misoprostol, stratified by parity, body mass index <40 kg/m2 or ≥40 kg/m2, and provider intent to use mechanical dilation at the onset of labor induction. Usual labor management was followed at the discretion of the provider. The primary outcome was time from induction to delivery. A priori, we estimated that 90 subjects per group (N=180) were needed for an 85% power to detect a 3-hour difference between groups with a type I error of 5%. Analysis was by intention-to-treat. A 2-sample t test was used for the primary outcome, Cohen's d was used as a measure of effect, and P values were reported. RESULTS: Of the 180 patients randomized, 88 were assigned to the 25 µg group and 92 were assigned to the 50 µg group. Of those, 96.1% of patients received the designated intervention. The baseline characteristics were similar between groups. No difference was found in the primary outcome of time to delivery (21.6 hours vs 18.6 hours; d=.28; 95% confidence interval, -0.02 to 0.57). In a planned subgroup analysis, multiparous patients delivered faster in the 50 µg group (15.2 hours vs 12.0 hours; d=.51; 95% confidence interval, 0.04-0.97). The risk for tachysystole associated with fetal heart tracing changes was rare overall (2.2%) and not significantly different between groups. No differences in maternal or neonatal adverse effects were observed. CONCLUSION: Patients with obesity who underwent cervical ripening with 50 µg of vaginal misoprostol experienced a similar time to delivery when compared with those who received 25 µg of misoprostol. However, multiparous patients had a significantly reduced time to delivery when 50 µg was used. A higher dose of misoprostol may be a promising intervention for reducing time in labor, which warrants further study.

OBJECTIVE: To develop a predictive model for peripartum infection among high risk laboring patients in Cameroon, Africa. STUDY DESIGN: We conducted a secondary analysis of the Cameroon Antibiotic Prophylaxis Trial (NCT03248297), a multicenter 3-arm double-blind randomized controlled trial of oral azithromycin ± amoxicillin among term pregnancies with prolonged labor or rupture of membranes in Cameroon 1/2018-5/2020. Patients with chorioamnionitis prior to randomization, study drug contraindications, or planned cesarean were excluded. The outcome of interest was a composite of maternal peripartum infection (chorioamnionitis, endometritis, sepsis by World Health Organization criteria, wound infection/abscess) diagnosed up to 6 weeks postpartum. Potential predictors were compared between patients with and without the composite outcome, and evaluated at a 0.05 alpha level. Statistically significant exposures were analyzed using multivariable regression (to generate adjusted odds ratios and 95 % confidence intervals) with backwards selection to generate a parsimonious model. Receiver operating characteristic curves with associated area under the curve assessed the model's predictive ability. A nomogram based on the final best fit multivariable model was constructed. RESULTS: Of 756 patients in the parent trial, 652 were analyzed: 45 (7 %) had peripartum infection. Those with infection were more likely to be nulliparous, lower education level, higher gestational age, receive antibiotics per hospital protocols, and undergo cesarean. In our best-fit multivariable model, none/primary education (vs university), cesarean birth, and antibiotic receipt per physician discretion (vs for cesarean prophylaxis) were significantly associated with increased infection risk. This model was moderately predictive (AUC = 0.75, 95 % CI 0.67-0.82). When using this 3 factor model, for a patient with a cesarean birth, receipt of antibiotics per physician discretion, and university education, the probability of peripartum infection was 35 % (95 % CI 0.11-0.73). CONCLUSIONS: While several variables such as parity are associated with infectious morbidity within 6 weeks among high risk laboring patients in Cameroon, only education level, antibiotic indication, and cesarean birth were independently associated, and a model including these 3 factors was moderately predictive. Validation of our findings in a larger population is warranted.

BACKGROUND: Leptin resistance occurs with obesity, but it is unknown if individuals at risk for obesity develop leptin resistance prior to obesity. OBJECTIVE: Investigate whether leptin resistance is independent of weight status in children at risk for obesity due to intrauterine exposure to maternal obesity or gestational diabetes mellitus (GDM). METHODS: Mother-child dyads (N = 179) were grouped by maternal pregnancy weight and GDM status: (1) normal weight, no GDM; (2) overweight/obesity, no GDM; (3) overweight/obesity with GDM. Children (4-10 years) were further stratified by current body mass index (BMI) <85th or ≥85th percentile. Leptin resistance of children and mothers was calculated as fasting leptin/fat mass index. Two-way ANOVA was used to assess whether leptin concentrations and leptin resistance differed by current weight status or in utero exposure group, after adjusting for race, sex and Tanner stage. RESULTS: Children with a BMI ≥85th percentile had more leptin resistance than those with a BMI <85th percentile (p < 0.001), but leptin resistance did not differ by in utero exposure. Similarly, leptin resistance in women was associated with weight status and not prior GDM. CONCLUSIONS: Results suggest that leptin concentrations are associated with obesity but not risk for obesity based on in utero exposure to maternal obesity or GDM.

BACKGROUND: Increased duration of breastfeeding improves maternal cardiovascular health and may be especially beneficial in high-risk populations, such as those with chronic hypertension. Others have shown that individuals with hypertension are less likely to breastfeed, and there has been limited research aimed at supporting breastfeeding goals in this population. The impact of perinatal blood pressure control on breastfeeding outcomes among people with chronic hypertension is unknown. OBJECTIVE: This study aimed to evaluate whether breastfeeding initiation and short-term duration assessed at the postpartum clinic visit differed according to perinatal blood pressure treatment strategy (targeting blood pressure <140/90 mm Hg vs reserving antihypertensive treatment for blood pressure ≥160/105 mm Hg). STUDY DESIGN: We performed a secondary analysis of the Chronic Hypertension and Pregnancy trial. This was an open-label, multicenter, randomized trial where pregnant participants with mild chronic hypertension were randomized to receive antihypertensive medications with goal blood pressure <140/90 mm Hg (active treatment) or deferred treatment until blood pressure ≥160/105 mm Hg (control). The primary outcome was initiation and duration of breastfeeding, assessed at the postpartum clinic visit. We performed bivariate analyses and log-binomial and cumulative logit regression models, adjusting models for variables that were unbalanced in bivariate analyses. We performed additional analyses to explore the relationship between breastfeeding duration and blood pressure measurements at the postpartum visit. RESULTS: Of the 2408 participants from the Chronic Hypertension and Pregnancy trial, 1444 (60%) attended the postpartum study visit and provided breastfeeding information. Participants in the active treatment group had different body mass index class distribution and earlier gestational age at enrollment, and (by design) were more often discharged on antihypertensives. Breastfeeding outcomes did not differ significantly by treatment group. In the active and control treatment groups, 563 (77.5%) and 561 (78.1%) initiated breastfeeding, and mean durations of breastfeeding were 6.5±2.3 and 6.3±2.1 weeks, respectively. The probability of ever breastfeeding (adjusted relative risk, 0.99; 95% confidence interval, 0.93-1.05), current breastfeeding at postpartum visit (adjusted relative risk, 1.01; 95% confidence interval, 0.94-1.10), and weeks of breastfeeding (adjusted odds ratio, 0.87; 95% confidence interval, 0.68-1.12) did not differ by treatment group. Increased duration (≥2 vs <2 weeks) of breastfeeding was associated with slightly lower blood pressure measurements at the postpartum visit, but these differences were not significant in adjusted models. CONCLUSION: In a secondary analysis of the cohort of Chronic Hypertension and Pregnancy trial participants who attended the postpartum study visit and provided breastfeeding information (60% of original trial participants), breastfeeding outcomes did not differ significantly by treatment group. This suggests that maintaining goal blood pressure <140/90 mm Hg throughout the perinatal period is associated with neither harm nor benefit for short-term breastfeeding goals. Further study is needed to understand long-term breastfeeding outcomes among individuals with chronic hypertension and how to support this population in achieving their breastfeeding goals.

BACKGROUND: Despite the known benefits of breastfeeding to infants and mothers, previous studies have demonstrated that underserved women are less likely to exclusively breastfeed. Existing studies on the impact of Special Supplemental Nutritional Program for Women, Infants, and Children enrollment on feeding decisions for infants have conflicting results with low-quality data and metrics. OBJECTIVE: This study aimed to examine infant feeding trends nationally in the first week postpartum over a 10-year period, comparing breastfeeding rates for primiparous women with low income who used Special Supplemental Nutritional Program for Women, Infants, and Children resources with those women who did not enroll. We hypothesized that although the Special Supplemental Nutritional Program for Women, Infants, and Children is an important resource for new mothers, free formula associated with enrollment in the Special Supplemental Nutritional Program for Women, Infants, and Children may disincentivize women to exclusively breastfeed. STUDY DESIGN: This was a retrospective cohort study of primiparous women with singleton gestations who gave birth at term and who responded to the Centers for Disease Control and Prevention Pregnancy Risk Assessment Monitoring System between 2009 and 2018. Data were extracted from phases 6, 7, and 8 of the survey. Women with low income were defined as those with a reported annual household income of $35,000 or less. The primary outcome was exclusive breastfeeding after 1 week postpartum. Secondary outcomes included ever breastfeeding, any breastfeeding after 1 week postpartum, and introduction of other liquids within 1 week postpartum. Multivariable logistic regression was used to refine risk estimates with adjustment for mode of delivery, household size, education level, insurance status, diabetes, hypertension, race, age, and BMI. RESULTS: Among the 42,778 women with low income who were identified, 29,289 (68%) of these women reported receiving Special Supplemental Nutritional Program for Women, Infants, and Children resources. There was no significant difference in the rates of exclusive breastfeeding after 1 week postpartum between those enrolled in the Special Supplemental Nutritional Program for Women, Infants, and Children and those not enrolled (adjusted risk ratio, 1.04; 95% confidence interval, 1.00-1.07; P=.10). However, those enrolled were less likely to ever breastfeed (adjusted risk ratio, 0.95; 95% confidence interval, 0.94-0.95; P<.01) and were more likely to introduce other liquids within 1 week postpartum (adjusted risk ratio, 1.16; 95% confidence interval, 1.11-1.21; P<.01). CONCLUSION: Although exclusive breastfeeding rates after 1 week postpartum were similar, women enrolled in the Special Supplemental Nutritional Program for Women, Infants, and Children were significantly less likely to ever breastfeed and more likely to introduce formula within the first week postpartum. This suggests that Special Supplemental Nutritional Program for Women, Infants, and Children enrollment may impact the decision to initiate breastfeeding and may represent an important window to test future interventions.

OBJECTIVE: This study aimed to compare the risks of adverse perinatal outcomes by body mass index (BMI) categories in healthy pregnant individuals delivered by term elective repeat cesarean (ERCD) to describe an optimal timing of delivery in otherwise healthy patients at the highest-risk BMI threshold. STUDY DESIGN: A secondary analysis of a prospective cohort of pregnant individuals undergoing ERCD at 19 centers in the Maternal-Fetal Medicine Units Network from 1999 to 2002. Nonanomalous singletons undergoing prelabor ERCD at term were included. The primary outcome was composite neonatal morbidity; secondary outcomes included composite maternal morbidity and individual components of the composites. Patients were stratified by BMI classes and to identify a BMI threshold for which morbidity was the highest. Outcomes were then examined by completed week's gestation, between BMI classes. Multivariable logistic regression was used to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI). RESULTS: A total of 12,755 patients were included in analysis. Patient's with BMI ≥ 40 had the highest rates of newborn sepsis, neonatal intensive care unit admissions, and wound complications. While a weight-related response was observed between BMI class and neonatal composite morbidity (p < 0.001), only those with BMI ≥ 40 had significantly higher odds of composite neonatal morbidity (aOR: 1.4, 95% CI: 1.0-1.8). In analyses of patients with BMI ≥ 40 (n = 1,848), there was no difference in the incidence of composite neonatal or maternal morbidity across weeks' gestation at delivery; however, as gestational age approached 39 to 40 weeks, rates of adverse neonatal outcomes decreased, only to increase again at 41 weeks' gestation. Of note, the odds of the primary neonatal composite were the highest at 38 weeks compared with 39 weeks (aOR: 1.5, 95% CI: 1.1-2.0). CONCLUSION: Neonatal morbidity is significantly higher in pregnant individuals with BMI ≥40 delivering by ERCD. Despite this increased perinatal morbidity, delivery prior to 39 and after 41 weeks in these patients is associated with increased neonatal risks. KEY POINTS: · Obese patients without additional comorbidities have higher rates of neonatal morbidity.. · Patients with BMI ≥ 40 carry the highest odds of poor perinatal outcomes.. · Earlier timing of delivery does not appear to reduce this risk..
RESUMO
As the worldwide prevalence of overweight and obesity continues to rise, so too does the urgency to fully understand mediating mechanisms, to discover new targets for safe and effective therapeutic intervention, and to identify biomarkers to track obesity and the success of weight loss interventions. In 2016, the American Heart Association sought applications for a Strategically Focused Research Network (SFRN) on Obesity. In 2017, 4 centers were named, including Johns Hopkins University School of Medicine, New York University Grossman School of Medicine, University of Alabama at Birmingham, and Vanderbilt University Medical Center. These 4 centers were convened to study mechanisms and therapeutic targets in obesity, to train a talented cadre of American Heart Association SFRN-designated fellows, and to initiate and sustain effective and enduring collaborations within the individual centers and throughout the SFRN networks. This review summarizes the central themes, major findings, successful training of highly motivated and productive fellows, and the innovative collaborations and studies forged through this SFRN on Obesity. Leveraging expertise in in vitro and cellular model assays, animal models, and humans, the work of these 4 centers has made a significant impact in the field of obesity, opening doors to important discoveries, and the identification of a future generation of obesity-focused investigators and next-step clinical trials. The creation of the SFRN on Obesity for these 4 centers is but the beginning of innovative science and, importantly, the birth of new collaborations and research partnerships to propel the field forward.

OBJECTIVE: In the OFFSITE II randomized controlled trial, outpatient cervical ripening with a Foley catheter (CF) in nulliparous patients undergoing elective induction of labor (eIOL) shortened the time from admission to delivery. Given that patients with obesity have protracted labor and higher rates of failed IOL, we sought to determine if outpatient ripening with a CF may be even more beneficial for this high-risk group. STUDY DESIGN: We performed a secondary analysis of the OFFSITE II randomized controlled trial. For this analysis, all patients from the primary trial were classified by their intervention assignment (inpatient vs. outpatient) and also by their admission body mass index (BMI) class (BMI ≥ 30 and BMI < 30 kg/m2). The primary outcome was time from labor and delivery (L&D) admission to delivery. Secondary outcomes included cesarean delivery, time from admission to hospital discharge, and rates of clinically diagnosed chorioamnionitis and endometritis. RESULTS: In patients with BMI ≥ 30, the primary outcome, time from admission to delivery, (18.0 [13.5-20.9] vs. 20.4 [16.6-31.3] hours, p = 0.01), as well as total hospitalization length (3.2 [2.5-3.3] vs. 3.4 [3.1-4.3] days, p = 0.02) were shorter in the outpatient group. There were no differences in rates of chorioamnionitis or endometritis in outpatient compared with inpatient CF. Furthermore, in those with a BMI ≥ 30, the cesarean rate was significantly lower with outpatient CF (19.4% vs. 44.7%, p = 0.03); it was not statistically different in patients with BMI < 30. CONCLUSION: In this exploratory retrospective secondary analysis of the OFFSITE II randomized control trial, we found that in patients with BMI ≥ 30 undergoing eIOL, outpatient CF was associated with a lower time from L&D admission until delivery. This was also associated with a shorter time of total hospital duration and decreased the rate of cesarean, a benefit not detected in the overall analysis presented in the primary study. In nulliparas undergoing induction of labor, ripening with outpatient cervical Foley may even more significantly reduce labor duration, total hospital duration, and the rate of cesarean in patients with obesity. KEY POINTS: · Outpatient CF was associated with a lower time from L&D admission until delivery in obese nulliparas.. · Outpatient CF was associated with a shorter time of total hospital duration in obese nulliparas.. · Outpatient CF was associated with a decreased rate of cesarean birth in obese nulliparas..

OBJECTIVE: To estimate the association between state-level abortion legislation and all-cause mortality among all females of reproductive age and maternal, fetal, and infant mortality. METHODS: We conducted a retrospective cohort study using the Centers for Disease Control and Prevention's WONDER (Wide-ranging ONline Data for Epidemiologic Research) database. Generalized estimating equations were used to estimate the association between supportive, moderate, and restrictive state abortion regulations and all-cause mortality in reproductive-aged females. Secondary outcomes included maternal, fetal, and infant mortality. The association of the number and type of laws on mortality were estimated. RESULTS: Moderate and supportive states were not associated with a significant decrease in all-cause mortality compared with restrictive states. Maternal mortality (per 100,000 live births) was significantly lower in moderate (-5.79, 95% CI -9.88 to -1.70) compared with restrictive states, but not supportive states (-2.51, 95% CI -6.75 to 1.72). Infant mortality (per 1,000 live births) was significantly lower in both moderate (-0.56, 95% CI -1.09 to -0.04) and supportive (-1.10, 95% CI -1.56 to -0.64) states. Fetal mortality was lower in moderate states (-0.69, 95% CI -1.18 to -0.20) but not in supportive states (-0.64, 95% CI -1.14 to 0.13). Each additional abortion regulation was associated with an increase in maternal mortality (1.09/100,000 live births, 95% CI 0.36-1.82) and infant mortality (0.20/1,000 live births, 95% CI 0.12-0.26). CONCLUSION: Moderate state abortion legislation was associated with lower rates of maternal, fetal, and infant mortality but not lower all-cause mortality in reproductive-aged females compared with restrictive laws. An increasing number of laws restricting abortion was associated with increased maternal and infant mortality.

OBJECTIVE: To examine the relationship between baseline renal function (serum creatinine, urine protein to creatinine ratio) in women with diabetes and adverse pregnancy outcomes. STUDY DESIGN: This was a retrospective cohort study of singleton pregnancies with pregestational diabetes and baseline renal function tests <20 weeks gestational age (wga) from the years 2007 to 2013. Those with baseline creatinine ≥1.2 mg/dL were excluded due to the association of renal disease with adverse outcomes. The primary outcome was the development of preeclampsia with severe features at <34 wga. Secondary outcomes were preeclampsia at any gestational age, preterm birth, indicated preterm birth, small for gestational age, and a neonatal adverse outcomes composite. The relationship between baseline renal function and the primary outcome was assessed with ROC curves. Objective cutoffs were determined by the Liu method. Outcomes were compared using univariable and multivariable analyses. RESULTS: Baseline renal function was assessed in 321 women with pregestational diabetes. With baseline serum creatinine <1.2 mg/dL serum creatinine was not associated with preeclampsia <34 weeks (AUC 0.47, 95% CI = 0.32-0.63). Urine protein to creatinine (UPC) ratio was moderately associated with preeclampsia <34 weeks with area under curve (AUC) 0.56 (0.39-0.74). Baseline creatinine above the Liu cutoff (0.65 mg/dL) was not significantly associated with primary or secondary outcomes (Table 1). UPC above the Liu cutoff (0.21) was significantly associated with severe preeclampsia <34 wga (24% vs 3.7%, aOR = 6.6, 95% CI = 2.1-20.8), with development of preeclampsia at any gestational age (56% vs 23.4%, aOR = 3.3, 95% CI = 1.4-7.9), and preterm birth (80% vs 36.2%, aOR 6.5 95% CI = 2.3-18.1). CONCLUSION: Creatinine was not associated with adverse pregnancy outcomes at thresholds <1.2 mg/dL in women with pregestational diabetes. Those with a baseline UPC ≥ 0.21 have an increased risk of preeclampsia and preterm delivery. Baseline 24 hr urine protein should be obtained in these patients to aid in counseling and future diagnosis of preeclampsia.Key PointsBaseline renal function tests are recommended in patients with pregestational diabetes, but values associated with pregnancy risk are poorly defined.This study evaluated the relationship between baseline renal function tests in patients with pregestational diabetes and adverse pregnancy outcomes.We found urine protein to creatinine ratio ≥0.21 to be associated with the development of severe preeclampsia <34 weeks gestational age as well as preeclampsia at any gestational age.

Objective: Obesity in pregnancy and gestational diabetes (GDM) increase cardiometabolic disease risk but are difficult to disentangle. This study aimed to test the hypothesis that 4-10 years after a pregnancy complicated by overweight/obesity and GDM (OB-GDM), women and children would have greater adiposity and poorer cardiometabolic health than those with overweight/obesity (OB) or normal weight (NW) and no GDM during the index pregnancy. Methods: In this cross-sectional study, mother-child dyads were stratified into three groups based on maternal health status during pregnancy (OB-GDM = 67; OB = 76; NW = 76). Weight, height, waist and hip circumferences, and blood pressure were measured, along with fasting glucose, insulin, HbA1c, lipids, adipokines, and cytokines. Results: Women in the OB and OB-GDM groups had greater current adiposity and poorer cardiometabolic health outcomes than those in the NW group (p < 0.05). After adjusting for current adiposity, women in the OB-GDM group had higher HbA1c, glucose, HOMA-IR and triglycerides than NW and OB groups (p < 0.05). Among children, adiposity was greater in the OB-GDM versus NW group (p < 0.05), but other indices of cardiometabolic health did not differ. Conclusions: Poor cardiometabolic health in women with prior GDM is independent of current adiposity. Although greater adiposity among children exposed to GDM is evident at 4-10 years, differences in cardiometabolic health may not emerge until later.
RESUMO
OBJECTIVE: A recent randomized controlled trial suggested that early gestational diabetes mellitus (GDM) screening in patients with obesity (body mass index [BMI] ≥30 kg/m2) does not improve perinatal outcomes. The American College of Obstetrics and Gynecology currently recommends early screening for gestational diabetes in patients who are overweight with one or more additional risk factors. We evaluated the effect of screening based on the number of additional risk factors for development of gestational diabetes. STUDY DESIGN: This was a secondary analysis of a multicenter randomized controlled trial of obese patients with singleton nonanomalous fetuses comparing early (14-20 weeks' gestation) with routine (24-28 weeks' gestation) GDM screening. Exclusion criteria were pregestational diabetes, major medical illnesses, bariatric surgery, chronic steroid use, and prior cesarean. Early versus routine GDM screening groups were compared and stratified by the number of additional risk factors for GDM (0, 1, 2, and ≥3). The primary outcome was an adverse perinatal composite outcome composed of: macrosomia, primary cesarean delivery, hypertensive disorders of pregnancy, shoulder dystocia, neonatal hyperbilirubinemia, and neonatal hypoglycemia. Analyses examined effects of early versus routine screening by the number of additional risk factors and their possible interaction on the incidences of the primary outcome and GDM. RESULTS: Of 913 patients, 5% had 0, 52% had 1, 33% had 2, and 10% had ≥3 additional risk factors. Baseline characteristics, including the number and type of risk factors, were similar between early and routine screening groups. Breslow-Day test for interaction between early versus routine screening and the number of additional risk factors was not significant for either the primary outcome (p = 0.37) or the diagnosis of GDM (p = 0.28). The incidence of GDM and the adverse perinatal composite outcome increased as the number of risk factors increased (p < 0.001). CONCLUSION: In patients with BMI ≥30 kg/m2 and additional risk factors, early GDM screening does not prevent adverse outcomes. KEY POINTS: · The ACOG currently recommends early screening for gestational diabetes if patients have risk factors.. · Even in patients with multiple risk factors, early screening for GDM does not improve outcomes.. · Patients with three or more risk factors may have worse outcomes if they undergo early screening..
RESUMO
OBJECTIVE: The random urine protein-to-creatinine ratio (UPCR) is a screening test used for predicting clinically significant proteinuria (urine protein ≥ 300 mg) during pregnancy. No consensus exists on the optimal random UPCR cutoff for performing follow-up 24 hour urine (24H) total protein collection. We aim to evaluate the test performance of random UPCR in predicting proteinuria in a contemporary cohort. STUDY DESIGN: This was a retrospective cohort study of pregnant patients at our institution from 2014 to 2018 with a random UPCR and follow-up 24H protein collection. The primary analysis estimated the test characteristics (sensitivity, specificity, positive and negative predictive values) of using random UPCR for the detection of proteinuria defined as urine protein ≥300 mg on 24H protein collection. UPCR cutoffs from 0.10 to 0.30 mg/dL were evaluated, receiver operator characteristic (ROC) curve was constructed, and area under the curve (AUC) was determined. A secondary analysis examined the correlation between UPCR and 24H protein using least squares regression and Pearson correlation. RESULTS: Paired UPCR and 24H collection results were available for 1,120 patients. Mean gestational age at time of UPCR was 31.1 ± 5.1 weeks and 687 (61.3%) of patients had a 24H ≥300 mg. UPCR <0.10 mg/dL effectively excluded proteinuria ≥300 mg on 24H collection, while UPCR ≥0.18 mg/dL correctly classifies proteinuria with 91% sensitivity, 57% specificity, 77% positive predictive value, and 79% negative predictive value. UPCR ≥1.07 mg/dL had 100% specificity for 24 hour proteinuria. The area under ROC curve was 0.86. UPCR and 24H collection were highly correlated with a Pearson correlation coefficient of 0.85. After our institution lowered the threshold to obtain a 24H from UPCR ≥0.20 mg/dL to ≥0.10 mg/dL in May 2017, the percentage of patients meeting criteria for 24H collection increased from 57.8 to 84.4%. CONCLUSION: The AUC and Pearson correlation suggest random UPCR is a high performance test for the prediction of proteinuria on 24H. Optimal test performance is dependent upon clinical consideration and upon the implications of the disease or condition. A random UPCR screen positive threshold of 0.18 mg/dL maximizes sensitivity to identify clinically significant proteinuria. KEY POINTS: · Random urine protein to creatinine ratio is a high performance test for proteinuria.. · A random UPCR threshold of 0.18 mg/dL maximizes sensitivity to identify proteinuria.. · Optimal test performance is dependent on the disease or clinical condition..
RESUMO
BACKGROUND: Patients with gestational diabetes mellitus are at increased risk for type 2 diabetes mellitus or glucose intolerance postpartum compared with those without diabetes mellitus. OBJECTIVE: We aimed to evaluate the association between early gestational diabetes mellitus and postpartum dysglycemia compared with gestational diabetes mellitus diagnosed by routine screening in a cohort of patients with obesity. STUDY DESIGN: This was a secondary analysis of a randomized controlled trial of patients with obesity and singleton, nonanomalous gestations that compared early gestational diabetes mellitus screening at 14 to 20 weeks of gestation with routine screening at 24 to 28 weeks of gestation. Patients were included in this analysis if they were diagnosed with gestational diabetes mellitus at the primary study site. The primary outcome was postpartum dysglycemia, defined as any abnormality on 2-hour oral glucose tolerance test 6 weeks postpartum or clinical diagnosis based on hyperglycemia requiring pharmacotherapy after delivery with deferred glucose tolerance test. Maternal characteristics and outcomes were compared in bivariable analysis, and logistic regression estimated the association between early gestational diabetes mellitus and postpartum dysglycemia. RESULTS: Of 119 patients included in this analysis, 30 were diagnosed by screening at <20 weeks of gestation and 89 at 24 to 28 weeks of gestation. Patients were overall similar in baseline characteristics. Patients with early gestational diabetes mellitus were more likely to have postpartum dysglycemia than those with gestational diabetes mellitus diagnosed with routine screening (36.7% vs 14.6%; odds ratio, 3.38; 95% confidence interval, 1.31-8.73). Most patients with early gestational diabetes mellitus who had postpartum dysglycemia were diagnosed clinically (n=7/11), whereas none of the patients with gestational diabetes mellitus established by routine testing were diagnosed with postpartum dysglycemia clinically. All (100%) patients with early gestational diabetes mellitus who completed a postpartum glucose tolerance test had dysglycemia compared with only 45% of patients with gestational diabetes mellitus diagnosed on routine screening. The proportion of patients who followed up for postpartum visits and the timing of follow-up were similar between groups. Postpartum glucose tolerance test completion was low but also similar between groups. CONCLUSION: Although postpartum glucose tolerance test completion is low, patients with gestational diabetes mellitus before 20 weeks of gestation, seem to be at higher risk for postpartum dysglycemia than those with gestational diabetes mellitus diagnosed at routine screening in a cohort of patients with obesity. Larger studies are needed to confirm these findings, but postpartum follow-up and diabetes mellitus testing may be even more important to improve long-term health in patients with early gestational diabetes mellitus.
