Pregnancy post-bariatric surgery: Improved outcomes with telephonic nutritional management program.

BACKGROUND: Pregnancies post-bariatric surgery are increasingly common. It is important to understand how to manage prenatal care in this high-risk population to optimize perinatal outcomes. OBJECTIVE: To determine among pregnancies post-bariatric surgery whether participation in a telephonic nutritional management program was associated with improved perinatal outcomes and nutritional adequacy. STUDY DESIGN: Retrospective cohort study of pregnancies post-bariatric surgery from 2012 to 2018. Participation in a telephonic management program with nutritional counseling, monitoring and nutritional supplement adjustment. Modified Poisson Regression estimated the relative risk using propensity score methods to account for baseline differences between the patients who participated in the program and patients who did not. RESULTS: 1575 pregnancies occurred post-bariatric surgery, of which 1142 (72.5 % of pregnancies) participated in the telephonic nutritional management program. Participants in the program were less likely than non-participants to have a preterm birth (aRR 0.48, 95 % CI 0.35-0.67), preeclampsia (aRR 0.43, 95 % CI (0.27-0.69)), gestational hypertension (aRR 0.62, 95 % CI 0.41-0.93), and to have neonates admitted to a Level 2 or 3 (aRR 0.61, 95 % CI0.39-0.94; aRR 0.66, 95 % CI 0.45-0.97, respectively), after adjusting for the propensity score to account for baseline differences. Risk of cesarean delivery, gestational weight gain, glucose intolerance and birthweight did not differ by participation. Among 593 pregnancies with nutritional labs available, participants in the telephonic program were less likely to have nutritional inadequacy in late pregnancy (aRR 0.91, 95 % CI 0.88-0.94). CONCLUSION: Participation in a telephonic nutritional management program post-bariatric surgery was associated with improved perinatal outcomes and nutritional adequacy.

Perinatal Outcomes After Bariatric Surgery Compared With a Matched Control Group.

OBJECTIVE: To evaluate perinatal outcomes associated with pregnancy after bariatric surgery within a large integrated health care system using propensity score matching. METHODS: We conducted a retrospective cohort study that evaluated perinatal outcomes in pregnant patients after bariatric surgery from January 2012 through December 2018. History of bariatric surgery was identified by using International Classification of Diseases codes and a clinical database. Primary outcomes were preterm birth (PTB), gestational hypertension, preeclampsia, impaired glucose tolerance or gestational diabetes, a large-for-gestational-age (LGA) or small-for-gestational-age (SGA) neonates, and cesarean birth. Propensity scores were estimated by using logistic regression that accounted for age at delivery, prepregnancy body mass index, year of delivery, parity, neighborhood deprivation index, race and ethnicity, insurance status, initiation of prenatal visit in the first trimester, smoking during pregnancy, chronic hypertension, and preexisting diabetes. Five patients in the control group were matched to each patient in the case group on linear propensity score, and modified Poisson regression was used to adjust for covariates. Sensitivity analyses by timing and type of surgery were performed. RESULTS: We identified a case cohort of 1,591 pregnancies in patients after bariatric surgery and a matched cohort of 7,955 pregnancies in patients who had not undergone bariatric surgery. Demographic characteristics were similar in both groups. In multivariate models, pregnancy after bariatric surgery was associated with a decreased risk of preeclampsia (7.5% vs 10.2%, adjusted relative risk [aRR] 0.72, 95% CI 0.60-0.86), gestational diabetes or impaired fasting glucose (23.5% vs 35.0%, aRR 0.73, 95% CI 0.66-0.80), and LGA (10.6% vs 19.9%, aRR 0.56, 95% CI 0.48-0.65) and an increased risk of SGA (10.9% vs 6.6%, aRR 1.51, 95% CI 1.28-1.78). No significant differences were observed in PTB, gestational hypertension and cesarean delivery. CONCLUSION: Pregnancy after bariatric surgery in a racially and ethnically diverse cohort of patients is associated with decreased risk of preeclampsia, gestational diabetes or impaired fasting glucose, and LGA neonates; it is also associated with an increased risk of SGA neonates compared with pregnant patients in a matched control group.

Training the Next Generation of Obstetrics and Gynecology Leaders, A Multi-Institutional Needs Assessment.

OBJECTIVE: To assess resident and faculty interest in, as well as content and preferred format for, a leadership curriculum during obstetrics and gynecology residency DESIGN: From June to July 2019, a needs assessment survey on leadership training was distributed to residents and academic faculty at 3 United States obstetrics and gynecology residency programs. Descriptive and bivariate analyses were performed. Open ended questions were analyzed for themes. SETTING: Three ob/gyn residency programs across the United States: Kaiser Permanente East Bay in Oakland, California, Baylor College of Medicine in Houston, Texas, and Weill Cornell Medicine in New York, New York. PARTICIPANTS: Surveys were distributed to all residents (n = 111) and affiliated academic faculty (n = 124) at each of the 3 participating sites. RESULTS: Resident response rate was 71% (79/111) and faculty rate was 63% (78/124). Postgraduate year (PGY) 1 residents were more likely to believe there was sufficient leadership training during residency (17/23, 74%) compared to PGY 2-4s (16/56, 29%) and faculty (20/76, 26%; p < 0.01). Most residents (66/79, 84%) and faculty (74/78, 82%) expressed that residents would benefit from a leadership curriculum. Both deemed small group exercises and leadership case studies taught by physicians were the preferred format for this curriculum. Residents and faculty agreed on 3 of the top 4 topics for a leadership curriculum - effective communication, team management, and time management - while residents chose self-awareness and faculty chose professionalism as the fourth of their top domains. Open-ended survey questions revealed that leadership demands in obstetrics and gynecology are similar to other specialties but differ in emphasis on crisis management, situational awareness, and advocacy training. CONCLUSIONS: Given unique aspects of leadership within the specialty, obstetrics and gynecology residents and faculty see benefit for specialty-specific formalized leadership training.

Fetomaternal hemorrhage: evaluation of recurrence within a large integrated healthcare system.

BACKGROUND: Fetomaternal hemorrhage is associated with severe fetal morbidity and mortality. The recurrence risk of fetomaternal hemorrhage is unknown. OBJECTIVE: We sought to establish the recurrence rate of fetomaternal hemorrhage in a large integrated healthcare system over a 10-year period. STUDY DESIGN: In this retrospective study within the Kaiser Permanente Northern California medical system, cases of fetomaternal hemorrhage were defined by either an elevated fetal hemoglobin level as determined by flow cytometry for a concerning pregnancy outcome (preterm delivery, perinatal demise, neonatal anemia, or transfusion within the first 2 days of life) or by perinatal demise with autopsy findings suggestive of fetomaternal hemorrhage. The outcomes of subsequent pregnancies were reviewed for features of recurrence. RESULTS: Within the 2008 to 2018 birth cohort of 375,864 pregnancies, flow cytometry testing for fetal hemoglobin levels was performed in 20,582 pregnancies. We identified 340 cases of fetomaternal hemorrhage (approximately 1 in 1100 births). Within the cohort of 340 affected pregnancies, perinatal loss was recorded for 80 (23.5%) pregnancies and 50 (14.7%) pregnancies delivered neonates who required transfusion. The affected patients had 225 subsequent pregnancies of which 210 were included in the analysis. Of these, 174 (82.9%) advanced beyond the threshold of viability and were delivered within our healthcare system. There was 1 case of recurrent fetomaternal hemorrhage identified. The recurrent case involved a spontaneous preterm delivery of an infant who was noted to have an elevated reticulocyte count but was clinically well. CONCLUSION: Within our large integrated healthcare system, approximately 1 in 1100 pregnancies was affected by fetomaternal hemorrhage within a 10-year period, which is comparable with previous studies. We identified 1 case of recurrence, yielding a recurrence rate of 0.5%. This infant did not have features of clinically important fetomaternal hemorrhage. This information can inform counseling of patients with affected pregnancies.

Perceptions of Intra-Uterine Device Users in Mirebalais, Haiti: A Mixed Methods Study.

INTRODUCTION: IUDs are safe, effective, and used worldwide to prevent unintended pregnancy. However, uptake in Haiti is low. There are limited data on IUD choice and experience in low resource settings; anecdotal reports from providers in Haiti have suggested that Haitian women are unlikely to choose to use or be satisfied with the IUD. The objective of this study is to explore the perceptions of a cohort of IUD users in Mirebalais, Haiti. METHODS: In June and July 2015, an IRB-approved mixed methods study of women over age eighteen with hormonal or copper IUDs inserted at Hôpital Universitaire de Mirebalais (HUM) was performed in Mirebalais, Haiti. RESULTS: Twenty-one eligible women participated, out of 58 women identified as eligible. Most women (81%) reported using the copper IUD; most (86%) had used the IUD for 6 months or more. Over half were under 30 years old (62%) and most had completed primary school or less (76%). Almost all (91%) reported prior pregnancies; 65% did not desire more children. The majority of participants were satisfied with the IUD, with 70% being very satisfied and 25% somewhat satisfied. Most women (71%) reported no very bothersome side effects, and would recommend the IUD to others (86%). Qualitative data highlighted positive perceptions of the IUD among users, as well as misperceptions and lack of knowledge regarding the IUD among members of their communities. CONCLUSION/IMPLICATIONS: Understanding of culture-specific perceptions is critical in addressing barriers to IUD uptake. Our findings indicate that IUDs can be an acceptable contraceptive method for women in Haiti, and suggest the possibility that increased access to the IUD may lead to increased acceptance of this method.

Visualizing the effect of dynamin inhibition on annular gap vesicle formation and fission.

Although gap junction plaque assembly has been extensively studied, mechanisms involved in plaque disassembly are not well understood. Disassembly involves an internalization process in which annular gap junction vesicles are formed. These vesicles undergo fission, but the molecular machinery needed for these fissions has not been described. The mechanoenzyme dynamin has been previously demonstrated to play a role in gap junction plaque internalization. To investigate the role of dynamin in annular gap junction vesicle fission, immunocytochemical, time-lapse and transmission electron microscopy were used to analyze SW-13 adrenocortical cells in culture. Dynamin was demonstrated to colocalize with gap junction plaques and vesicles. Dynamin inhibition, by siRNA knockdown or treatment with the dynamin GTPase inhibitor dynasore, increased the number and size of gap junction 'buds' suspended from the gap junction plaques. Buds, in control populations, were frequently released to form annular gap junction vesicles. In dynamin-inhibited populations, the buds were larger and infrequently released and thus fewer annular gap junction vesicles were formed. In addition, the number of annular gap junction vesicle fissions per hour was reduced in the dynamin-inhibited populations. We believe this to be the first report addressing the details of annular gap junction vesicle fissions and demonstrating a role of dynamin in this process. This information is crucial for elucidating the relationship between gap junctions, membrane regulation and cell behavior.
