Objective This study aimed to systematically review the relative effectiveness of preincision cefazolin with or without adjunctive prophylaxis (macrolides or metronidazole) vs cefazolin alone in decreasing the incidence of postcesarean delivery surgical site infections. Data Sources We performed a systematic search on PubMed, Ovid EMBASE, Google Scholar, ClinicalTrials.gov , and the Cochrane Central Register of Controlled Trials from October 25, 2020, to November 25, 2020, to identify studies comparing cefazolin with adjunctive macrolides or metronidazole with cefazolin alone. The reference lists were reviewed, and a manual search of articles published after the last database search was performed. Study Eligibility Criteria Overall, 3 randomized controlled trials and 1 prospective observational study of reproductive-age women undergoing cesarean deliveries were included in the study. We excluded studies of women who were immunocompromised (eg, patients who were HIV positive) or women with a diagnosis of chorioamnionitis before cesarean delivery. All patients received first-line cefazolin (either cefazolin 1 g or 2 g). We compared preincision cefazolin alone with preincision cefazolin plus adjunctive therapy (500 mg, oral or intravenous formulations of azithromycin, metronidazole, or clarithromycin). Methods A total of 6 review authors independently assessed the risk of bias for each study, using the Cochrane Risk of Bias criteria. Synthesis and further appraisal were done using the Grading of Recommendations, Assessment, Development, and Evaluation levels and the American College of Obstetricians and Gynecologists appraisal guidelines. Disagreements were resolved by discussion. Treatment effects were evaluated using meta-analysis, and pooled relative risks and 95% confidence intervals were generated using random-effects models using the Review Manager 5 software (version 5.4.1). Results Overall, 3 randomized controlled trials and 1 prospective observational study representing 2613 women met the criteria for inclusion. Significant reductions in surgical site infections (relative risk, 0.46; 95% confidence interval, 0.34–0.63; 3 randomized controlled trials) and the duration of hospital stay (weighted mean difference, −1.46; 95% confidence interval, −2.21 to −0.71; 2 randomized controlled trials) were observed with preincision cefazolin and adjunctive prophylaxis compared with cefazolin alone. No significant difference was observed in maternal febrile morbidity (relative risk, 0.38; 95% confidence interval, 0.11–1.25; 2 randomized controlled trials). Conclusion Our findings have provided evidence for the use of preincision adjunctive extended-spectrum prophylaxis with cefazolin over cefazolin alone. However, future investigations are required to establish the relative efficacies of different adjunctive antibiotic options.

Objective To compare the success rate, complications, and hospital length-of-stay of 3 modalities of minimally invasive management of tubo-ovarian abscesses (TOAs): laparoscopy, ultrasound-guided drainage, and computed tomography–guided drainage. Data Sources Electronic-based search in PubMed, EMBASE, Ovid MEDLINE, Google Scholar, and Cochrane Central Register of Controlled Trials, using the following Medical Subject Heading terms: “minimally invasive surgical procedures,” “drainage,” “abscess,” “tubo-ovarian,” “ovarian diseases,” and “fallopian tube diseases.” Methods of Study Selection Of the 831 articles in the initial results, 10 studies were eligible for inclusion in our systematic review. Tabulation, Integration, and Results A total of 975 patients were included in our study; 107 (11%) had laparoscopic drainage procedures, and 406 (42%) had image-guided (ultrasound or computed tomography) drainage of TOAs. Image-guided TOA drainage had higher success rates (90%–100%) than laparoscopic drainage (89%–96%) and the use of antibiotic treatment alone (65%–83%). Patients treated with image-guided drainage had no complications (for up to 6 months of follow-up) and shorter lengths of hospital stay (0–3 days on average) compared with laparoscopic drainage (5–12 days) or conservative management with antibiotics alone (7–9 days). Conclusion Although conservative management of TOAs with antibiotics alone remains first-line, our review indicates that better outcomes in the management of TOA were achieved by minimally invasive approach compared with conservative treatment with antibiotics only. Of the minimally invasive techniques, image-guided drainage of TOAs provided the highest success rates, the fewest complications, and the shortest hospital stays compared with laparoscopy. The low magnitude of evidence in the included studies calls for further randomized trials. This systematic review was registered in the International Prospective Register of Systematic Review (register, http://www.crd.york.ac.uk/PROSPERO;CRD 42020170345).

The purpose of this study is to build and validate a statistical model to predict infection after caesarean delivery (CD).Patient and surgical variables within 30 d of CD were collected on 2419 women. Postpartum infection included surgical site infection, urinary tract infection, endomyometritis and pneumonia. The data were split into model development and internal validation (1 January-31 August; N = 1641) and temporal validation subsets (1 September-31 December; N = 778). Logistic regression models were fit to the data with concordance index and calibration curves used to assess accuracy. Internal validation was performed with bootstrapping correcting for bias.Postoperative infection occurred in 8% (95% CI 7.3-9.9), with 5% meeting CDC criteria for surgical site infections (SSI) (95% CI 4.1-5.8). Eight variables were predictive for infection: increasing BMI, higher number of prior Caesarean deliveries, emergent Caesarean delivery, Caesarean for failure to progress, skin closure using stainless steel staples, chorioamnionitis, maternal asthma and lower gestational age. The model discriminated between women with and without infection on internal validation (concordance index = 0.71 95% CI 0.67-0.76) and temporal validation (concordance index = 0.70, 95% CI 0.62, 0.78).Our model accurately predicts risk of infection after CD. Identification of patients at risk for postoperative infection allows for individualized patient care and counseling.

The purpose of this study is to identify the rate of catheter-associated urinary tract infection (CAUTI) after Cesarean delivery (CD) and to determine if any factors increase risk of infection.A retrospective cohort study was performed at a multi-center institution for patients who underwent CD in 2013. All patients had urinary catheters inserted before surgery. Diagnosis followed IDSA guidelines with culture growing greater than 10Of 2419 patients, 36 patients developed CAUTI (1.5%). In the 24 (66.7%) cases diagnosed by IDSA guidelines, Escherichia coli was the most common causative organism (54.1%); followed by Enterococcus faecalis (16.7%), Streptococccus agalactiae (8.3%), and Group A Streptococcus (8.3%). Longer operative time (OR 1.013; 95% 1.002-1.023; p = .02) and pregnancies complicated by STI (OR 4.15; 95% CI 1.11-15.0; p .05) were associated with higher rates of CAUTI.The overall rate of CAUTI after CD was low at 1.5%. Escherichia coli was the most common causative pathogen. Identification of the patients at high risk for CAUTI allows for risk reduction measures.

The primary objective of the study was to determine the risk of postpartum urinary tract infection (UTI) in women exposed to intermittent versus indwelling catheterization in labor. The secondary objective was to identify risk factors for development of postpartum UTI. A case-control study was conducted between 1 January 2013 and 31 December 2016. Cases were defined as patients who were diagnosed with UTI and controls were not diagnosed with UTI. Obstetrical, infectious, and catheterization variables were collected. Univariate and multivariate analyses were performed. A total of 26,517 full-term vaginal deliveries occurred during the study period with a rate of postpartum UTI of 0.7%. There were 166 cases and 695 controls included in the analysis. There was no significant difference in the rate of UTI between patients who underwent indwelling versus intermittent (reference) catheterization (OR 1.05, 95% CI: 0.67–1.64, p = .826). On multivariate analysis, significant risk factors for UTI included the relationship between use of catheterization and duration of labor (p = .026) and history of UTI during the pregnancy (p In this study, there was no difference in the rate of postpartum UTI based on catheterization method. Further studies are needed to determine the optimal method of catheterization during labor and to enable providers to implement quality improvement strategies aimed at decreasing the risk of infection.

Molecular tests to diagnose conditions involving the disruption of normal microbiota are difficult to optimize. Using Nugent-scored Gram stain (NS) as the reference standard, we evaluated the performance of 3 molecular assays for the diagnosis of bacterial vaginosis (BV) and examined the impact of an incremental increase in bacterial targets. The BD Affirm assay includes a DNA probe for Gardnerella vaginalis, the Hologic transcription-mediated amplification (TMA) analyte-specific reagent (ASR) assay adds a second Lactobacillus sp. target, and the recently cleared in vitro diagnostic use (IVD) Aptima BV assay includes a third target (Atopobium vaginae). The diagnosis of vulvovaginal candidiasis (VVC) by the Affirm and Candida vaginitis Hologic TMA ASR assays was assessed using microscopy for yeast as the reference standard. From May to December 2018, 111 women with vaginitis symptoms prompting the clinician to order an Affirm test were enrolled with informed consent for the collection of additional specimens. Clinicians accurately predicted BV as the most likely diagnosis for 71% of the 45 patients with BV. Coinfection occurred in 13.5% of patients. For BV, the specificity of the Aptima IVD assay (86.3%) was higher than the Affirm assay (60.6%, P = 0.0002), but sensitivities were not significantly different. For VVC, the sensitivity of the ASR assay (100%) was higher than Affirm (75.9%; P = 0.023) and the specificity of the Affirm assay (98.8%) was higher than the ASR assay (86.6%; P = 0.004).

Background:The 2019 coronavirus disease pandemic poses unique challenges to healthcare delivery. To limit the exposure of providers and patients to severe acute respiratory syndrome coronavirus 2, the Centers for Disease Control and Prevention encourages providers to use telehealth platforms whenever possible. Given the maternal mortality crisis in the United States and the compounding 2019 coronavirus disease public health emergency, continued access to quality preconception, prenatal, intrapartum, and postpartum care are essential to the health and well-being of mother and baby.Objective:This commentary explores unique opportunities to optimize virtual obstetric care for low-risk and high-risk mothers at each stage of pregnancy.Methods:In this review paper, we present evidence-based literature and tools from first-hand experience implementing telemedicine in obstetric care clinics during the pandemic.Results:Using the best evidence-based practices with telemedicine, health care providers can deliver care in the safest, most respectful, and appropriate way possible while providing the critical support necessary in pregnancy. In reviewing the literature, several studies endorse the implementation of specific tools outlined in this article, to facilitate the implementation of telemedicine. From a quality improvement standpoint, evidence-based telemedicine provides a solution for overburdened healthcare systems, greater confidentiality for obstetric services, and a personalized avenue for health care providers to meet maternal health needs in the pandemic.Conclusion:During the COVID-19 pandemic, continued access to quality prenatal, intrapartum, and postpartum care are essential to the health and well-being of mother and baby.

To identify the rate of surgical site infection (SSI) after Cesarean delivery (CD) and determine risk factors predictive for infection at a large academic institution.This was a retrospective cohort study in women undergoing CD during 2013. SSIs were defined by Centers for Disease Control (CDC) criteria. Chi square and t-tests were used for bivariate analysis and multivariate logistic regression was used to identify SSI risk factors.In 2419 patients, the rate of SSI was 5.5% (n = 133) with cellulitis in 4.9% (n = 118), deep incisional infection in 0.6% (n = 15) and intra-abdominal infection in 0.3% (n = 7). On multivariate analysis, SSI was higher among CD for labor arrest (OR 2.4; 95%CI 1.6-3.5; p .001). Preterm labor (OR 2.8; 95%CI 1.3-6.0; p = .01) and general anesthesia (OR 4.4; 95%CI 2.0-9.8; p = .003) were predictive for SSI. Increasing BMI (OR 1.1; 95%CI 1.05-1.09; p = .02), asthma (OR 1.9; 95%CI 1.1-3.2; p = .02) and smoking (OR 1.9; 95%CI 1.1-3.2; p = .02) were associated with increased SSI.Several patient and surgical variables are associated with increased rate of SSI after CD. Identification of risk factors for SSI after CD is important for targeted implementation of quality improvement measures and infection control interventions.

To identify the rate of postpartum endomyometritis (PPE) after cesarean delivery (CD) in the era of antibiotic prophylaxis and determine risk factors.A single institution retrospective study was performed in women undergoing CD. Data regarding obstetrical and surgical variables were collected. Diagnosis of PPE was made clinically.Among 2419 patients, the rate of PPE was 1.6% (n = 38) and was associated with lower age (27.0 versus 31.0; p .001). 65.7% of patients having chorioamnionitits developed PPE, but only 5.4% of patients without PPE had chorioamnionitis (p .001). On multivariate analysis, PPE was higher in emergent versus scheduled CD (OR: 5.89; p = .0081). There was no difference in PPE for cefazolin 2 g versus 1 g (OR: 1.91; p = .17) or 3 g versus 1 g (OR: 3.69; p = .29), gentamicin/clindamycin versus cefazolin (OR: 5.60; p .001) had higher PPE. Women with PPE were more likely to have labor arrest (OR: 4.336; p = .001), sexually transmitted infection during the pregnancy (OR: 4.197; p = .02) or blood transfusion (OR: 9.50; p .0001).While the overall rate of PPE was low, several risk factors were identified. Preoperative diagnosis of chorioamnionitits is associated with a higher rate of PPE. Further studies are needed to identify optimal regimens for antimicrobial prophylaxis in women undergoing CD.

Vulvar and vaginal disorders are among the most common problems seen in ambulatory care. The cause is usually infectious, but noninfectious causes should also be considered, and differentiating them can be challenging. Accurate diagnosis based on patient history, physical examination, and laboratory testing is necessary so that effective therapy can be chosen.

Objective: Mycoplasma genitalium has been recognized as a cause of male urethritis, and there is now evidence suggesting it causes cervicitis and pelvic inflammatory disease (PID) in women. Methods: Prevalence, risk factors and co-infections with other sexually transmitted pathogens were collected in a cross-sectional study looking at 400 women at the gynecologic clinics of a university medical center in the United States. Bacterial vaginosis and trichomoniasis were diagnosed using Amsel’s criteria, gram stain and trichomonas culture respectively. Cervicitis and PID were clinically diagnosed. After testing for Chlamydia trachomatis and Neisseria gonorrhoeae, the residual cervical swab transport medium (Gen-Probe/Hologic®) was stored at -70°C. Stored samples were later analyzed for M. genitalium by a research use only transcription-mediated amplification assay using procedures similar to those established for APTIMA Combo2 assay for C. trachomatis and N. gonorrhoeae (Gen-Probe/Hologic®). Results: The overall prevalence of infection with C. trachomatis, N. gonorrhoeae, T. vaginalis and M. genitalium was found to be 7.8%, 1.8%, 10.43% and 8.9%, respectively. Prevalence of M. genitalium was comparable to that of C. trachomatis and greater than the prevalence of N. gonorrhoeae. Univariate analysis of M. genitalium status showed that participants with lower condom use had an increased probability of M. genitalium (p=0.037). Conclusion: Prevalence of M. genitalium was comparable to C. trachomatis in our study, but more research is needed to clarify pathogenicity.
