Assessing patient perceptions of cytomegalovirus infection in pregnancy.

Pregnant women impacted by cytomegalovirus (CMV) make clinical decisions despite uncertain outcomes. Intolerance of uncertainty score (IUS) is a validated measure of tendency for individuals to find unacceptable that a negative event might occur. We investigated patient perceptions of CMV infection during pregnancy and correlated IUS and knowledge with decision-making. Electronic questionnaire was sent to women from July to August 2017. The questionnaire evaluated knowledge of CMV, IUS, and responses regarding management to three clinical scenarios with escalating risk of CMV including choices for no further testing, ultrasound, amniocentesis, or abortion. For each scenario, logistic regression was used to model IUS on responses. A total of 815 women were included. The majority of participants was white (63.1%) and 42% had a postgraduate degree. Over 70% reported that they had not previously heard of CMV. In the scenario with only CMV exposure, participants with increasing IUS were more likely to choose abortion (odds ratio [OR] = 1.04; 95% confidence interval [CI]: 1.01, 1.06) and no further testing (OR = 0.97; 95% CI: 0.95, 0.99). In the scenario with mild ultrasound findings in setting of CMV exposure, increasing IUS was associated with higher odds of choosing no further testing (OR = 0.97; 95% CI, 0.94, 0.99). No significant association was observed between IUS and responses in the scenario with severe ultrasound abnormalities in setting of CMV exposure. The majority of patients had no knowledge of CMV. Higher IUS was associated more intervention in low severity scenarios, but in severe scenarios, IUS was not associated with participants' choices.

Postpartum Weight Loss in Women with Class-III Obesity: Do They Lose What They Gain?

OBJECTIVE: Excessive gestational weight gain (GWG) increases risk of postpartum weight retention in normal and overweight women but little is known about weight retention in morbidly obese women. We evaluated the impact of GWG on postpartum weight retention in women with class-III obesity. STUDY DESIGN: This is a retrospective cohort of pregnancies at a single institution from July 2013 to December 2017 complicated by body mass index (BMI) ≥ 40 at entry to care. Women were classified as GWG within (WITHIN), less than (LESS), or greater than (MORE) Institute of Medicine's (IOM) recommendations. Women were excluded for multiples, late prenatal care, preterm birth, fetal anomalies, intrauterine demise, weight loss, and missing data. Primary outcome was achievement of intake weight at the postpartum visit. Logistic regression was used to adjust for confounding factors. RESULTS: Among 338 women, 93 (28%) gained WITHIN, 129 (38%) LESS, and 144 (43%) MORE. Women in the MORE group were less likely to achieve their intake weight at the postpartum visit (adjusted odds ratio [AOR] = 0.09 95% confidence interval [CI]: 0.05-0.17, p < 0.01). Women gaining MORE were the only group who did not lose weight from intake to postpartum (Median weight change [LESS: -14 lbs (IQR: -20 to -7)] vs. [WITHIN: -7 lbs (IQR: -13 to -1)] vs. [MORE: 5 lbs (IQR: 0-15)]; p < 0.01). CONCLUSION: Excessive GWG in women with class-III obesity is associated with postpartum weight retention.

Gestational Weight Gain and Postpartum Depression in Women with Class III Obesity.

OBJECTIVE: We investigated the association between gestational weight gain (GWG) and postpartum depression (PPD) in women with class III obesity. STUDY DESIGN: This is a retrospective cohort of women with body mass index (BMI) ≥ 40 kg/m2 at entry to care, first prenatal visit ≤14 weeks gestation, with singleton, nonanomalous pregnancies who delivered at term from July 2013 to December 2017. Women missing data regarding PPD were excluded. Primary outcome was PPD; classified as Edinburgh Postnatal Depression Scale (EPDS) score >13/30 or provider's report of depression. Participants were classified, according to Institute of Medicine GWG guidelines (11-20 pounds), as either less than 11 pounds (LT11) or at/more than 11 pounds (GT11). Bivariate statistics compared demographics and pregnancy characteristics. Logistic regression used to estimate odds of primary outcome. RESULTS: Of 275 women, 96 (34.9%) gained LT11 and 179 (65.1%) gained GT11 during pregnancy. The rate of PPD was 8.7% (n = 24), 9 (9.4%) in the LT11 group and 15 (8.4%) in the GT11 group (p = 0.82, odds ratio: 1.13, 95% confidence interval [CI]: 0.48, 2.69). When controlling for entry BMI and multiparity, adjusted odds of PPD was 1.07 (95% CI: 0.44, 2.63). No correlation was found between GWG and EPDS. CONCLUSION: A relationship between GWG and PPD in class III obese women was not found in this cohort.

Pregnancy Outcomes of Exacerbated Chronic Hypertension Compared with Superimposed Preeclampsia.

OBJECTIVE: Compare outcomes in women with chronic hypertension who remain normotensive, experience exacerbation, or meet laboratory criteria for superimposed preeclampsia. STUDY DESIGN: This is a retrospective cohort study of singleton pregnancies with chronic hypertension from 2000 to 2014. Delivery admission records were used to categorize women into three groups: stable chronic hypertension, exacerbated hypertension, and superimposed preeclampsia. The primary outcomes were a neonatal composite of death, respiratory support, umbilical arterial pH < 7, 5-minute Apgar ≤3, and seizures, in addition to maternal severe hypertension requiring intravenous (IV) antihypertensives. RESULTS: In total, 270 women (31.3%) had stable hypertension, 429 (49.8%) had exacerbated hypertension, and 163 (18.9%) had superimposed preeclampsia. Neonatal composite (10.7 vs. 11.2 vs. 21.5%; p < 0.01) and preterm birth <35 weeks (8.8 vs. 18.3 vs. 35.7%; p < 0.01) were highest in the superimposed preeclampsia group. Severe hypertension requiring the use of IV antihypertensives increased across groups (0 vs. 15.6 vs. 23.3% p < 0.01). With the exception of severe hypertension requiring IV antihypertensive use, outcomes in women with exacerbations were unchanged compared with those with stable hypertension. CONCLUSION: Superimposed preeclampsia is associated with an increased risk of adverse neonatal outcomes compared with stable chronic hypertension, whereas exacerbation of chronic hypertension is not.

Impact of Interval between Screening and Diagnosis of Gestational Diabetes on Pregnancy Outcomes.

Objective Current standard of care in the United States uses a two-step screening and diagnosis approach for gestational diabetes mellitus (GDM). We aimed to assess the impact of the interval between screening and diagnosis on maternal and perinatal outcomes. Materials and Methods This is a retrospective cohort study of singleton pregnancies complicated by GDM at a single tertiary center from 2007 to 2013. Women were divided into three groups based on the interval between their screening and diagnostic tests: ≤ 7, 8 to 14, and > 14 days. Maternal outcomes were mode of delivery, White class A2GDM, and preeclampsia. Perinatal outcomes included preterm birth, birth weight, macrosomia, hypoglycemia, and birth injury. Results Chart review revealed 1,212 women with diagnosis of GDM and 565 were included in the analysis with 310 (55%) women ≤ 7 days, 149 (26%) women within 8 to 14 days, and 106 (19%) women > 14 days group. All maternal and perinatal outcomes were similar between groups including risk of cesarean delivery, A2GDM, preeclampsia, macrosomia, preterm birth, hypoglycemia, and birth injury. Conclusion Increasing time interval between screening and diagnosis may not negatively affect maternal or perinatal outcomes in pregnancies complicated by GDM.

Evaluating gestational weight gain recommendations in pregestational diabetes.

OBJECTIVE: The Institute of Medicine (IOM) does not provide recommendations for gestational weight gain (GWG) specific to women with pregestational diabetes. We aimed to assess the impact of GWG outside the IOM recommendations on perinatal outcomes. STUDY DESIGN: We performed a retrospective cohort study of all singletons with pregestational diabetes from 2008 through 2013. Women were classified as GWG within, less than, or greater than IOM recommendations for body mass index per week of pregnancy. Maternal outcomes examined were cesarean delivery, preeclampsia, and percentage of visits with glycemic control (>50% blood sugars at goal). Neonatal outcomes were birthweight, small for gestational age (<10th percentile), large for gestational age (LGA) (>90th percentile), macrosomia (>4000 g), preterm delivery (<37 weeks), and birth injury (shoulder dystocia, fracture, brachial plexus injury, cephalohematoma). Groups were compared using analysis of variance and χ(2) test, as appropriate. Backwards stepwise logistic regression was used to adjust for confounding factors. RESULTS: Of 340 subjects, 37 (10.9%) were within, 64 (18.8%) less than, and 239 (70.3%) greater than IOM recommendations. The incidence of cesarean delivery, preeclampsia, glycemic control, preterm delivery, and birth injury were not significantly different between GWG groups. The incidence of LGA and macrosomia increased as GWG category increased (adjusted odds ratio [AOR], 3.08; 95% confidence interval [CI], 1.13-8.39 and AOR, 4.02; 95% CI, 1.16-13.9, respectively) without decreasing the incidence of small for gestational age (AOR, 0.34; 95% CI, 0.10-1.19). Increases in the risk in LGA and macrosomia were not explained by differences in glycemic control by GWG groups. CONCLUSION: Women with pregestational diabetes mellitus should be counseled to gain within the IOM recommendations to avoid LGA and macrosomic newborns.

The impact of excessive gestational weight gain timing on neonatal outcomes in women with class III obesity.

OBJECTIVE: This study evaluated the influence of early gestational weight gain (GWG) on neonatal outcomes among women with class III obesity. STUDY DESIGN: Retrospective cohort of women with class III obesity who gained more than the Institute of Medicine (IOM) guidelines (>20lbs). Women gaining ≥75% of total gestational weight prior to 28 weeks (EWG) were compared to women gaining <75% of their total weight prior to 28 weeks (SWG). The primary outcome was a neonatal composite morbidity and mortality. Secondary outcomes included individual components of composite and LGA. RESULTS: Of 144 women identified, 42 (29.2%) had EWG and 102 (70.8%) had SWG. Though 11% of the total population had composite neonatal morbidity, this did not differ between groups (p = .4). LGA was nearly twice as common in the SWG group (41% vs 26%, p = .13). EWG was associated with decreased risk of LGA (AOR 0.25 95% CI 0.08, 0.78) and lower median birth weight (AOR -312 g 95% CI -534.7, -90.2). CONCLUSION: Though adverse neonatal outcomes were common in this population, timing of gestational weight gain was not correlated. Increased rates of LGA and higher median birth weight in the SWG group suggests excessive GWG continuing in the third trimester of pregnancy may be of import for neonatal size.

The Effect of Non-penicillin Antibiotic Regimens on Neonatal Outcomes in Preterm Premature Rupture of Membranes.

Objective A 7-day course of a penicillin (PCN) and macrolide is standard of care (SAR) in preterm premature rupture of membranes (PPROM). Data regarding alternative antibiotic regimens are limited. We sought to assess the impact of non-PCN regimens on neonatal outcomes. Study Design Secondary analysis of randomized controlled trial of antenatal magnesium sulfate. Singleton, nonanomalous pregnancies complicated by PPROM at > 24 weeks of gestation receiving the SAR were compared with women receiving a non- ß -lactam regimen and a macrolide (NPCR). Primary outcome was a neonatal composite. Secondary outcomes included pregnancy latency, endometritis, and chorioamnionitis. Results A total of 949 women met inclusion criteria; 821(56%) received the SAR and 128(8.8%) received NPCR. Adjusted models did not demonstrate worse outcomes (AOR [adjusted odds ratio] = 0.50; 95% CI [confidence interval]: 0.22-1.11). Neonates receiving SAR were less likely to have bronchopulmonary dysplasia (BPD; p = 0.03) but more likely to have severe necrotizing enterocolitis (sNEC; p = 0.04). Risk for chorioamnionitis and median latency did not differ between groups but women receiving the SAR were less likely to get endometritis (AOR = 0.35; 95% CI: 0.14-0.91). Conclusions In this cohort, receiving NPCR in the setting of PPROM did not impact the overall risk of adverse neonatal outcomes or latency, but did increase the risk of endometritis. Alterations in individual neonatal morbidities suggest follow-up studies are needed.

Evaluation of Institute of Medicine Guidelines for Gestational Weight Gain in Women with Chronic Hypertension.

Objective To assess the impact of gestational weight gain (GWG) outside the Institute of Medicine (IOM) recommendations on perinatal outcomes in pregnancies complicated by chronic hypertension (HTN). Methods The study consisted of a retrospective cohort of all singletons with HTN from 2000 to 2014. Maternal outcomes examined were superimposed preeclampsia and cesarean delivery. Neonatal outcomes were small for gestational age (SGA), large for gestational age (LGA), and preterm birth (PTB). Groups were compared using analysis of variance and chi-squared test for trend. Backward stepwise logistic regression was adjusted for confounding factors. Results Of 702 subjects, 106 (15.1%) gained within, 176 (25.0%) gained less, and 420 (59.8%) gained more weight than the IOM recommendations. After adjusting for confounders, GWG above IOM recommendations remained associated with LGA (adjusted odds ratio [AOR]: 2.53, confidence interval [CI] 95%:1.29-4.95). Weight gain less than recommended was associated with a decreased risk of superimposed preeclampsia (AOR: 0.49, CI 95%: 0.26-0.93) without increasing the risk of SGA (AOR: 1.03, CI 95%: 0.57-1.86). Conclusion Women with pregnancies complicated by chronic HTN should be counseled regarding the association of LGA with excessive GWG. Additionally, they should be counseled that weight gain below recommendations may be associated with a decreased risk of superimposed preeclampsia; however, this association deserves further investigation.
