Synthetic vs nonsynthetic slings for female stress and mixed urinary incontinence: a systematic review and meta-analysis.

OBJECTIVE: This study aimed to systematically review objective and subjective success and surgical outcomes of suburethral sling surgery for female patients with stress or mixed urinary incontinence using synthetic vs nonsynthetic material with corresponding surgical approaches (retropubic or transobturator). DATA SOURCES: We systematically searched Medline, Embase, EBM Reviews, ClinicalTrials.gov, and Web of Science Core Collection using standardized Medical Subject Headings (MeSH) without date restrictions (PROSPERO-registered). We double-screened studies and used backward citation chaining. STUDY ELIGIBILITY CRITERIA: We included peer-reviewed randomized controlled trials and prospective or retrospective comparative studies examining outcomes of retropubic or transobturator synthetic vs nonsynthetic (autologous, allograft, or xenograft) slings for female stress or mixed urinary incontinence, with available English or French full texts. We excluded minislings (single insertion point). We allowed slings for recurrent stress or mixed urinary incontinence, and slings concomitant with prolapse surgery, with at least 6 weeks of postoperative follow-up. We excluded systematic reviews, meta-analyses, review studies, case-control studies, case reports, studies that did not describe surgical approach or material, and studies of combination slings. METHODS: We evaluated study quality using RoB, the Cochrane risk-of-bias tool for randomized controlled trials, and the Newcastle-Ottawa scale for observational studies. We used pooled relative risk with 95% confidence intervals to estimate the effect of sling material type on each outcome through meta-analysis and meta-regression, as appropriate. RESULTS: We screened 4341 abstracts, assessed 104 full texts, and retained 35 articles (30 separate studies). For retropubic synthetic vs nonsynthetic slings, there was no difference in the number of objectively or subjectively continent patients. The rates of reoperation for stress urinary incontinence and overall were higher with nonautologous retropubic slings than with synthetic slings. Compared with autologous slings, retropubic synthetic slings were associated with higher subjective continence in populations with ≥25% recurrent stress urinary incontinence (relative risk, 1.27; 95% confidence interval, 1.12-1.43). There were no differences in continence between transobturator synthetic and nonsynthetic slings. Subjective satisfaction was better in the transobturator synthetic group than in the autologous sling group (relative risk, 1.42; 95% confidence interval, 1.03-1.94). CONCLUSION: Synthetic and nonsynthetic slings have comparable objective and subjective success, with synthetic materials generally showing better operative outcomes and fewer complications.

Task shifting cesarean sections in low- and middle-income countries: A systematic review and meta-analysis.

BACKGROUND: Safe and timely access to cesarean section (CS) in low- and middle-income countries (LMIC) remains a significant challenge. OBJECTIVES: To compare maternal and perinatal outcomes of CS by non-physician clinicians (NPCs) versus physicians in LMIC. SEARCH STRATEGY AND SELECTION CRITERIA: A systematic search of Ovid MEDLINE, EMBASE, Cochrane Library (including CENTRAL), Web of Science, and LILACS was performed from inception to January 2022. DATA COLLECTION AND ANALYSIS: Data were extracted by two independent reviewers and meta-analysis was performed when possible. MAIN RESULTS: Ten studies from seven African countries were included. There was no significant difference in maternal mortality for CS performed by NPCs versus physicians (odds ratio [OR] 1.09, 95% confidence interval [CI] 0.56-2.14, P = 0.8, I2  = 70%, P < 0.05, eight studies, n = 20 711) or in perinatal mortality (OR 1.18, 95% CI 0.86-1.61, P = 0.3, I2  = 88%, n = 19 716). Despite heterogeneous clinical settings between providers, there was no difference in the rates of wound infection or re-operation, although there was a higher rate of wound complications (such as dehiscence) in the NPC group (OR 1.89, 95% CI 1.21-2.95, P = 0.005, n = 6507). CONCLUSIONS: NPCs have comparable maternal and neonatal outcomes for CS compared with standard providers, albeit with increased odds of wound complication. PROSPERO REGISTRATION: CRD42020217966.

Maternal anxiety, depression and vascular function during pregnancy.

OBJECTIVE: We aim to clarify whether type and timing of mental health symptoms in early pregnancy distinctly contribute to maternal-fetal vascular function, independent from the psychotropic medications given to treat these conditions. METHODS: Data from a prospective cohort study (n = 1678) were used to test whether self-reported fears about giving birth and depressive symptoms prior to 16 weeks of gestation were associated with vascular outcomes predictive of hypertensive disorders of pregnancy (HDP) i.e., systolic and diastolic blood pressure (BP); uterine artery pulsatility index (UAPI); umbilical artery resistance index (UmbARI); and urine protein creatinine ratio. Multiple linear regressions models and mediation models were used to test for associations between predictors and outcomes, controlling for previously identified risk factors for vascular dysfunction such as maternal age and history of infertility. RESULTS: Fears about giving birth in early pregnancy were inversely associated with UmbARI (ß = -0.33, p = 0.03, df = 51) mid- to late-pregnancy (≥20 weeks). Depressive symptoms in early pregnancy were also inversely associated with maternal systolic BP (ß = -0.13, p = 0.01, df = 387) and diastolic BP (ß = -0.10, p = 0.04, df = 387) during the first trimester. CONCLUSIONS: While fears about giving birth in early pregnancy were associated with lower vascular resistance in the fetal-placental unit, early depressive symptoms were associated with lower maternal vascular tone. At the very least, our results support the notion that early maternal psychological distress is unlikely to account for the development of HDP later during pregnancy and provide preliminary evidence to support distinct roles of pregnancy-related anxiety and depressive symptoms in maternal-fetal vascular function.

Effect of double embryo transfer derived from autologous frozen oocytes on multiple pregnancy rates and presentation of success rates stratified by age at retrieval

Objective: To compare outcomes transferring one or two embryos in autologous frozen oocyte cycles. Material and Methods: A retrospective cohort study conducted at an academic fertility center between January 2012 and December 2018. One-hundred and fourteen patients underwent frozen oocyte transfers; 67 single embryo transfer (SET) and 47 double embryo transfer (DET). No subjects had more than two embryos transferred. Data were analyzed using t-test and chi-squared testing. Multivariate logistic regression was used to control for confounding effects. Power analysis suggested an 82% power with alpha of 5% and effect size of 27%. Results: Regarding the embryo stage, 72% were cleavage embryos and 28% were blastocyst embryos. Among those who had cleavage stage embryos, 48.8% underwent SET and 51.2% underwent DET. In the blastocyst embryos group these proportions were 84.4% and 15.6%, respectively. There were no difference in pregnancy rate for SET (40.3%) vs DET (36.2%) (p=0.78). Additionally, the live birth rate did not differ between SET and DET (28.4 vs 19.1%, respectively, p=0.26). The multivariate multilevel analysis provided adjusted odds ratios (95% confidence interval) of: 1.85 (0.46-7.44) for pregnancy; 0.497 (0.05-4.86) for clinical pregnancy; and 0.82 (0.11-6.29) for live birth when comparing SET and DET. Multiple pregnancy rates were significantly lower in the SET (0%), compared with DET group (44.4%) (p<0.002). Conclusion: SET results in excellent live birth outcomes in autologous frozen oocyte cycles. However DET results in significantly increased rates of multiple pregnancies. This suggests that SET is a viable option in autologous frozen oocyte cycles.

Advanced parental age: Is it contributing to an increased incidence of non-syndromic craniosynostosis? A review of case-control studies.

BACKGROUND: Craniosynostosis (CS) is a congenital birth defect characterized by the premature fusion of one or several calvarial suture(s). CS could lead to serious complications, such as intracranial hypertension and neurodevelopmental impairment. There is an increasing trend in the prevalence of CS - 75% of which are of non-syndromic type (NSCS). In parallel, there is a steady rise in the average maternal age. The goal of this paper was to review the literature to clearly identify any associations between parental age and NSCS. This review was performed and reported in compliance with PRISMA guidelines. METHODS: The PUBMED and EMBASE databases were systematically searched, and all studies that observed the relationship between maternal and/or paternal age on NSCS were included. The articles were then assessed for methodological quality using the Newcastle-Ottawa Scale (NOS). The effect of advanced maternal and/or paternal age on the incidence of NSCS was identified by the prevalence ratios reported at a confidence interval of 95%. RESULTS: Six retrospective case-control studies, reporting on a total of 3267 cases of NSCS were included in this review. While there were some inconsistencies in the findings of the different studies, the majority reported a positive correlation between advanced maternal and/or paternal age and an increased incidence of NSCS. CONCLUSION: This review identified an association between advanced parental age and an increased incidence of NSCS.

BRCA testing in women with high-grade serous ovarian cancer: gynecologic oncologist-initiated testing compared with genetics referral.

OBJECTIVE: Up to 15% of patients with high-grade serous ovarian, tubal, or peritoneal carcinoma harbor a mutation in BRCA genes. Early notion of mutation status may facilitate counseling, predict prognosis, and increase access to Parp-inhibitors. The aim of this study was to examine the rate of germline genetic testing in a retrospective cohort of women with high-grade serous ovarian, tubal, or peritoneal carcinoma to determine if a new pilot project of gynecologic oncologist-initiated genetic testing improved the rate of testing, after 1 year of implementation. METHODS: Gynecologic oncology-initiated genetic testing was implemented at a single university hospital center with input and collaboration from gynecological oncologists, nurses, and genetic counselors. All patients diagnosed with high-grade serous ovarian, tubal, or peritoneal carcinoma after August 2017 were offered gynecologic oncologist- initiated genetic testing for a panel of 13 hereditary breast and ovarian cancer susceptibility genes. Data from this group was then compared with a historic cohort of patients who received traditional genetic counseling between January 2014 and August 2017 (control group). Patients that had genetic testing through a clinical trial were excluded. The primary outcome was the uptake of genetic testing in both groups. Secondary outcomes included difference in time from diagnosis to genetic result between both cohorts. Data was analyzed using SPSS 25.0 and medians (ranges) were reported. RESULTS: A total of 152 women with high-grade serous ovarian, tubal, or peritoneal carcinoma were included in this study. Between January 2014 to July 2017 there were 108 patients with high-grade serous ovarian, tubal, or peritoneal carcinoma, among which 50.9% (n=54) underwent genetic testing following referral to genetics. The prevalence of BRCA pathogenic variants was 25.9% (14/54): 9.2% (5/54) in BRCA1 and 16.7% (9/54) in BRCA2. The median time from diagnosis to genetics referral was 53 days (range; 3-751), and median time from diagnosis to test result disclosure was 186 days (range; 15-938). After 1 year of implementation of the gynecologic oncologist-initiated genetic testing model, among 44 women diagnosed with high-grade serous ovarian, tubal, or peritoneal carcinoma, 86.2% underwent genetic testing. The median time from diagnosis to result disclosure decreased to 58 days, representing a reduction of 128 days, or 4.27 months (P<0.001). Reasons for non-testing included refusal, death, and follow-up at another hospital. The prevalence of germline BRCA1/2 pathogenic variants was 21% (8/38). CONCLUSION: Gynecologic oncologist-initiated genetic testing at the time of high-grade serous ovarian, tubal, or peritoneal carcinoma diagnosis leads to increased uptake and decreased delays in testing compared with referral for traditional genetic counseling.

Supplements to Conventional Treatment After Hysteroscopic Lysis of Intrauterine Adhesions: A Systematic Review.

Intrauterine adhesions (IUAs) are a result of trauma to the basalis layer of the endometrium and may lead to clinical sequelae such as miscarriage, infertility, and menstrual irregularities. Hysteroscopy is recognized as the gold standard in diagnosis and management, although the optimal treatment after surgical intervention remains unclear. This review aimed to provide an update on the treatment options available after hysteroscopic adhesiolysis and to facilitate clinical management of patients with IUAs. To avoid duplicating previous work, the review focused on studies that compared various adjunctive postoperative treatments in patients receiving hormone therapy. Of 548 studies, 15 papers fit our criteria that compared post-resection treatment options in women with IUAs. Meta-analysis of the use of Foley catheter or amnion graft as an adjunctive therapy after adhesiolysis failed to show a statistical difference (odds ratio 1.55; 95% confidence interval 0.60-3.99). Meta-analysis could not be done for the 13 remaining studies as a result of extensive heterogeneity, bias, or non-comparable end points. The lack of a universal classification system for IUAs and the use of variable outcomes to measure the success of adjunctive treatment pose challenges in generating standard treatment recommendations. This review calls for the development of a universal classification system and studies with consistent parameters and end points to allow for the generation of standard treatment guidelines. On the basis of the available evidence, recommendation of specific adjunctive treatments after hysteroscopic adhesiolysis is unjustified.
