Background: The objective of this study was to compare the outcomes of 2 consecutive pregnancies of the same women who conceived after restrictive bariatric surgeries., Methods: A retrospective study comparing consecutive pregnancy outcomes of the same women, who conceived before and twice after a restrictive bariatric surgery, was conducted., Results: This study included 109 women, and therefore, 327 paired pregnancies: 109 pregnancies preceded and 218 followed restrictive bariatric surgery (87% had laparoscopic banding, and 13% had silastic ring vertical gastroplasty). Both prepregnancy and predelivery body mass index were significantly lower after bariatric surgery (36.7±4.4 versus 31. 5±5.5, P<.001; 40.6±5.5 versus 35.3±6.1, P<.001; respectively). This effect was preserved at the subsequent pregnancy (31.5±5.5 versus 31.3±6.3, P = .609, and 35.3±6.1 versus 35.1±5.9, P = .706, respectively). The rates of hypertensive disorders and gestational diabetes mellitus were significantly lower after the bariatric operation, for the first and the second pregnancy (21% versus 7.4% and 4.7%, P = .009, and 19% versus 5.6% and. 6.6%, P = .007, respectively). The rate of macrosomic newborn was significant lower in the second postbariatric pregnancy (11.1% before versus 1.1% after second pregnancy, P = .02). Using multiple logistic regression models controlling for maternal age, prepregnancy body mass index, and the type of surgery, the reduction in hypertensive disorders (adjusted odds ratio (OR) .3, 95% confidence interval (CI) .12-.82; P = .018 for the first postoperative pregnancy and adjusted OR .2, 95% CI .06-.64; P = .007 for the second postoperative pregnancy), and gestational diabetes mellitus (adjusted OR .2, 95% CI .06-.48; P = .001 for the first postoperative pregnancy and adjusted OR .3, 95% CI .05-.51; P = .002 for the second postoperative pregnancy) remained significant., Conclusions: A significant decrease in pregnancy complications, such as hypertensive disorders and gestational diabetes mellitus, is achieved after a restrictive bariatric surgery. This improvement is maintained at the second subsequent pregnancy., (© 2013 American Society for Bariatric Surgery Published by American Society for Metabolic and Bariatric Surgery All rights reserved.)

Background: Overweight and obesity have been shown to be associated with increased adverse pregnancy outcomes. Weight reduction improves maternal health status and reduces the risk of pregnancy complications, as well as long-term consequences. Our objective was to compare the pregnancy outcomes of the same women who delivered before and after bariatric surgery., Methods: A retrospective study comparing pregnancy outcomes, of the same women, delivered before and after a bariatric surgery was conducted. The observed deliveries occurred from 1988 to 2008 at Soroka University Medical Center, the sole tertiary hospital in the southern region of Israel., Results: The present study included 288 paired pregnancies: 144 deliveries before and 144 after bariatric surgery. A significant reduction in the prepregnancy and predelivery maternal body mass index was noted after bariatric surgery (36.37 ± 5.2 versus 30.50 ± 5.4 kg/m(2), P < .001; and 40.15 ± 4.92 versus 34.41 ± 5.42 kg/m(2), P < .001; respectively). Only 8 patients (5.6%) were admitted during their pregnancy for bariatric complications. Pregnancy complications, such as hypertensive disorders (31.9% versus 16.6%; P = .004) and diabetes mellitus (20.8% versus 7.6%; P = .001), were significantly reduced after bariatric surgery. The rate of cesarean deliveries because of labor dystocia was significantly lower after bariatric surgery (5.6% versus 2.1%, P < .05). Using a multiple logistic regression model, controlling for maternal age, the reduction in hypertensive disorders (odds ratio .4, 95% confidence interval .2-.8) and diabetes mellitus (odds ratio .15, 95% confidence interval .1-.4) remained significant., Conclusion: A significant decrease in pregnancy complications, such as hypertensive disorders and diabetes mellitus, is achieved after bariatric surgery., (Copyright © 2012 American Society for Metabolic and Bariatric Surgery.

Objective: We sought to compare pregnancy outcome of patients who conceived during or after the first year postbariatric surgery., Study Design: A retrospective study comparing pregnancy outcome between patients who conceived during or after the first postoperative year was conducted., Results: The study included 104 pregnancies of patients who conceived during and 385 who conceived after the first postoperative year. Prepregnancy and predelivery body mass index were comparable between the groups. No significant differences were noted regarding hypertensive disorders (15.4% in the early vs 11.2% in the late postoperative pregnancy; P = .392); diabetes mellitus (11.5% vs 7.3%; P = .392); perinatal outcomes, such as congenital malformations (1.9% vs 1.3%; P = .485); or bariatric complications (6.7% vs 7.0%; P = .392) between the groups. Using multiple logistic regression models, controlling for confounders, the interval (in months) was not associated with pregnancy complications., Conclusion: Patients who conceived during the first postoperative year had comparable short-term perinatal outcome compared with patients who conceived after the first postoperative year., (Copyright © 2011 Mosby, Inc.

Objective: This study was undertaken to determine fetal heart rate (FHR) tracing patterns associated with congenital hypothyroidism., Study Design: FHR patterns of 59 women whose babies were diagnosed with congenital hypothyroidism were retrospectively compared with tracings of 78 of their siblings. Tracings were interpreted during the first stage of labor. Multivariable analysis was used to control for confounders., Results: Neonates with congenital hypothyroidism had significantly higher rates of reduced variability in FHR tracing patterns as compared with those without congenital hypothyroidism (49.2% vs 3.8%; odds ratio, 24.1; 95% confidence interval, 6.8-85.3; P < .001). No significant differences were noted between the groups regarding decelerations or baseline abnormalities. The significant association between congenital hypothyroidism and reduced variability persisted after controlling for confounders such as treatment with pethidine, MgSO4, and gestational age (odds ratio, 14.1; 95% confidence interval, 1.1-190.7; P = .046)., Conclusion: Congenital hypothyroidism is significantly and independently associated with reduced variability in FHR tracing patterns.
