Medical Management of Ovarian Endometriomas: A Systematic Review and Meta-analysis.

OBJECTIVE: To estimate the effect of medical management on the size of ovarian endometriomas. DATA SOURCE: Online databases were searched from inception to October 2022, including Ovid MEDLINE, Ovid EMBASE, PubMed, EBM Reviews-Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov , and Web of Science. METHODS OF STUDY SELECTION: Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we included all English-language, full-text articles that reported on change in endometrioma size (either diameter or volume) after medical interventions. Studies evaluating surgical interventions or postoperative recurrence were excluded. All screening and data extraction were performed independently by two authors. Risk of bias assessment was performed with either the Cochrane Risk of Bias Tool for randomized controlled trials or a modified Newcastle-Ottawa Scale for observational studies. TABULATION, INTEGRATION, AND RESULTS: After removal of duplicates, 9,332 studies were screened, with 33 full-text articles deemed eligible for inclusion. In the meta-analysis, dienogest showed significant reduction in cyst diameter (reduction 1.32 cm, 95% CI, 0.91-1.73, eight studies, n=418 cysts) and volume (mean difference of log-transformed volume 1.35, 95% CI, 0.87-1.83, seven studies, n=282 cysts). Similarly, significant reductions were seen with the oral contraceptive pill (OCP) (1.06 cm, 95% CI, 0.59-1.53, nine studies, n=455), gonadotropin-releasing hormone (GnRH) agonists (1.17 cm, 95% CI, 0.42-1.92, four studies, n=128 cysts), norethindrone acetate (0.6 cm, 95% CI, 0.27-0.94, two studies, n=88 cysts), and danazol (1.95 cm, 95% CI, 1.18-2.73, two studies, n=34 cysts). Norethindrone acetate with aromatase inhibitor was also effective in reducing endometrioma volume (mean difference of log-transformed volume 1.47, 95% CI, 0.16-2.78, two studies, n=34 cysts). CONCLUSION: Medical management with dienogest, OCPs, GnRH agonists, norethindrone acetate, norethindrone acetate with aromatase inhibitor, or danazol can reduce the size of ovarian endometriomas.

Evaluation of a clinical protocol for the management of fever in labor among pregnant women at term: A quality-improvement study.

OBJECTIVE: To assess the impact of a quality-improvement initiative designed to increase diagnostic accuracy and adequate management of clinical chorioamnionitis (CC) at a tertiary center. Chorioamnionitis occurs in 1%-13% of term pregnancies and increases maternal and neonatal peripartum complications; often over-diagnosed, it leads to unnecessary investigations and treatments. METHODS: This was an interrupted time-series study. In September 2017 two interventions were implemented: (1) staff training and (2) standardized clinical protocol for the management of fever in labor. All singleton term pregnancies were included. CC cases were reviewed in the pre-intervention (2015-2016, n = 179) and post-intervention (2017-2018, n = 142) groups. CC criteria based on the American College of Obstetricians and Gynecologists guidelines, antibiotics, maternal and neonatal outcomes, and pathology were compared. A cost-consequence analysis was performed. RESULTS: Incidence of CC decreased from 8.2 to 5.6 per 10 person-year (P < 0.001). This was associated with a significant increase in diagnostic accuracy from 15.7% to 73.2% (P < 0.001). Weight-adjusted tobramycin dosage improved from 8.8% to 69.1% (P < 0.001). Maternal length of hospitalization and readmissions decreased significantly, without affecting neonatal sepsis rate. Interventions decreased yearly hospital costs associated with CC by 23.4%. CONCLUSION: Standardizing the management of fever in labor significantly increased the diagnostic accuracy of CC and decreased the misuse of antibiotics in term pregnancies. CC costs decreased by 23.4%.

Timing of delivery in obese women and risk of stillbirth.

PURPOSE: Increased body mass index (BMI) is an independent risk factor for stillbirth. The purpose of this study was to determine an optimal time of delivery at term in obese women in order to decrease the risk of stillbirth in this population. METHODS: We conducted a retrospective population-based cohort study using the CDC's Period Linked Birth-Infant Death and Fetal Death data. The study population included all singleton, term births with a recorded pre-pregnancy BMI that occurred between 2014 and 2017. Unconditional logistic regression analyses were used to estimate the risk of stillbirth in each BMI class at each gestational week from 37 weeks and onwards comparing with births to normal-weight women at 41 weeks. RESULTS: Of 12,742,980 births in our cohort, 46.8% were to women with a normal BMI, 26.9% were to women who were classified as overweight, 14.5% were to women in obesity class I, 7.3% in obesity class II, and 4.8% in obesity class III. Within each BMI class, the risk of stillbirth increased with gestational age, with the most pronounced rises in risk occurring at later gestational ages. In a dose-response relationship, the risk of stillbirth exceeded that of a normal BMI pregnancy at 41 weeks at the following gestational age and BMI category: obese class 1 at 39 weeks (OR 1.15 95% CI 1.00-1.31), obese class II at 38 weeks (OR 1.21 95% CI 1.04-1.41) and obese class III at 37 weeks (OR 1.30 95% CI 1.11-1.52). CONCLUSION: Compared to women with a normal BMI at 41 weeks, there was a higher risk of stillbirth at term in women with each increase in BMI class. Consideration should be given to early induction among these women to reduce the risk of stillbirth.

Induction of labor at 39 weeks and risk of cesarean delivery among obese women: a retrospective propensity score matched study.

OBJECTIVES: To evaluate if induction of labor (IOL) in obese women at 39 weeks of gestation decreases the risk of cesarean delivery (CD). METHODS: We conducted a retrospective propensity score matched study using the Center for Disease Control's (CDC's) Period Linked Birth-Infant Death data. The study population consisted of cephalic singleton births to women with BMI greater or equal to 30.0 kg/m2 who delivered at or beyond 39 weeks between 2013 and 2017. Women with prior CD were excluded. Women who underwent IOL at 39 weeks were propensity score matched 1:5 on the basis of CD risk factors to women who did not undergo IOL at 39 weeks but may have had an IOL at a later gestational age. Conditional logistic regression compared CD rates and maternal outcomes between obese women induced at 39 weeks with those not induced at 39 weeks. RESULTS: Our cohort consisted of 197,343 obese women induced at 39 weeks and 986,715 obese women not induced at 39 weeks. Overall, the risk of CD among women who had an IOL at 39 weeks was lower than those without an IOL at 39 weeks, 0.59 (0.58-0.60). The decrease in CD risk was more pronounced in multiparas, 0.47 (0.46-0.49) than nulliparas, 0.81 (0.79-0.83). When stratified by BMI, the effect of IOL on lowering CD risk was similar across all obesity classes. Aside from an increased risk of instrumental deliveries, morbidities were comparable in both groups. CONCLUSIONS: IOL at 39 weeks among obese women appears to lower the risk of CD, without compromising maternal outcomes.
