Chronic endometritis: screening, treatment, and pregnancy outcomes in an academic fertility center.

PURPOSE: To identify the prevalence of chronic endometritis (CE), compare the efficacy of antibiotic regimens for CE, and examine pregnancy outcomes after treatment for CE among patients in an academic fertility clinic. METHODS: In this retrospective cohort study, data from patients who underwent endometrial sampling (ES) for CE evaluation at a single academic institution from 2014 to 2020 were collected and analyzed. Rates of CE were compared by indication for ES including recurrent pregnancy loss (RPL), implantation failure (IF), and recent first-trimester pregnancy loss. Treatment and pregnancy outcomes were also evaluated. RESULTS: Six hundred fifty-three individuals underwent ES to evaluate for CE. The overall prevalence of CE was 28.5%; when stratified by indication, the prevalence of CE was 66.2% for recent first-trimester loss, 27.9% for RPL, and 13.1% for IF (p < .001). Of those with CE, 91.9% received antibiotics, most commonly doxycycline (76.0%). CE clearance was not significantly different when doxycycline was compared to all other regimens (71.3% vs. 58.8%, p = .17), and 68.5% of patients cleared CE after one course of antibiotics. Following two antibiotic courses, CE was cleared in 88.3% of patients. Live birth rates (LBRs) were higher for those with cleared CE compared to patients with untreated CE (34.1% vs. 5.6%, p = .014) and similar for those with cleared CE versus those without CE (34.1% vs. 29.3%, p = .297). CONCLUSION: CE is common among patients with infertility, particularly those with a recent first-trimester loss. Treatment and clearance of CE were associated with higher LBRs; however, persistent CE was common despite treatment with antibiotics.

Anxiety, attitudes, and education about fertility among medical students in the United States.

BACKGROUND: As delayed family building is common among physicians, the goal of this study was to evaluate childbearing plans, anxiety related to future fertility, and interest in fertility education among medical students. METHODS: Using convenience and snowball sampling methods, an electronic REDCap survey was distributed via social media and group messaging applications to medical students enrolled in medical schools across the United States. Answers were collected, and analysis of the descriptive statistics was performed. RESULTS: The survey was completed by 175 participants, 72% of which were female (assigned at birth). The mean (± SD) age of participants was 24.9 ± 1.9 years. Of all participants, 78.3% desire to have children and 65.1% of these individuals plan to delay childbearing. On average, the planned age of first pregnancy is 31.0 ± 2.3 years. "Lack of time" was the greatest influence on decision regarding timing of childbearing. Of all respondents, 58.9% reported at least some anxiety related to future fertility. When females and males were compared, significantly more females (73.8%) versus males (20.4%) reported worrying about future fertility (p < 0.001). Participants reported that greater knowledge about infertility and potential treatments would help ease fertility related anxiety, and 66.9% of respondents showed interest in learning about how things such as age and lifestyle can impact fertility, preferably through medical curricula, videos, and podcasts. CONCLUSION: A majority of the medical students in this cohort intend to have children and most plan to delay childbearing. A large percentage of female medical students reported anxiety related to future fertility, but many students showed interest in receiving fertility education. This study highlights an opportunity for medical school educators to incorporate targeted fertility education into their curriculum with the intention of decreasing anxiety and improving future reproductive success.

Atrial fibrillation with rapid ventricular response as a maternal presentation of mirror syndrome: a case report.

Mirror syndrome is the phenomenon of fetal hydrops causing maternal edema and weight gain. Here, we report a case of arrhythmia as the primary maternal symptom. A 36-year-old woman, G2P1001, at 34.5 weeks of gestation presented with new-onset fetal hydrops combined with maternal weight gain and edema. She developed atrial fibrillation with rapid ventricular response; cardiac workup was unremarkable. Rate control was achieved with diltiazem. She underwent delivery and reverted to normal sinus rhythm on post-operative day 1. Volume overload causes atrial wall stress and neurohormonal changes that may trigger atrial fibrillation. Optimization with rate control facilitated good maternal and fetal outcomes in this case.

A Retrospective Test-Negative Case-Control Study to Evaluate Influenza Vaccine Effectiveness in Preventing Hospitalizations in Children.

BACKGROUND: Vaccination is the primary strategy to reduce influenza burden. Influenza vaccine effectiveness (VE) can vary annually depending on circulating strains. METHODS: We used a test-negative case-control study design to estimate influenza VE against laboratory-confirmed influenza-related hospitalizations among children (aged 6 months-17 years) across 5 influenza seasons in Atlanta, Georgia, from 2012-2013 to 2016-2017. Influenza-positive cases were randomly matched to test-negative controls based on age and influenza season in a 1:1 ratio. We used logistic regression models to compare odds ratios (ORs) of vaccination in cases to controls. We calculated VE as [100% × (1 - adjusted OR)] and computed 95% confidence intervals (CIs) around the estimates. RESULTS: We identified 14 596 hospitalizations of children who were tested for influenza using the multiplex respiratory molecular panel; influenza infection was detected in 1017 (7.0%). After exclusions, we included 512 influenza-positive cases and 512 influenza-negative controls. The median age was 5.9 years (interquartile range, 2.7-10.3), 497 (48.5%) were female, 567 (55.4%) were non-Hispanic Black, and 654 (63.9%) children were unvaccinated. Influenza A accounted for 370 (72.3%) of 512 cases and predominated during all 5 seasons. The adjusted VE against influenza-related hospitalizations during 2012-2013 to 2016-2017 was 51.3% (95% CI, 34.8% to 63.6%) and varied by season. Influenza VE was 54.7% (95% CI, 37.4% to 67.3%) for influenza A and 37.1% (95% CI, 2.3% to 59.5%) for influenza B. CONCLUSIONS: Influenza vaccination decreased the risk of influenza-related pediatric hospitalizations by >50% across 5 influenza seasons.

Differences in maternal group B Streptococcus screening rates in Latin American countries.

OBJECTIVE: To determine rates and results of maternal Group B streptococcus (GBS) screening during pregnancy and identify sociodemographic characteristics associated with GBS screening in Latin American countries. BACKGROUND: GBS is a primary cause of morbidity and mortality in neonates and is prevented by screening pregnant women for GBS before delivery and intrapartum antibiotic treatment. Yet, data regarding national GBS screening practices and the epidemiology of maternal GBS colonization in Latin America are limited. METHODS: We conducted a retrospective observational study using de-identified records of pregnant women in six Latin American countries from a regional database. 460,328 collected from January 1, 2009 through December 31, 2012 met study criteria and were included. Maternal screening rates for GBS were determined, association of demographic variables (ethnicity, age, education level, and civil status) with maternal GBS screening was determined using logistic regression, odds ratios were calculated comparing incidence of adverse neonatal outcomes (sepsis, pneumonia, and meningitis) between countries with high and low rates of GBS screening, maternal GBS colonization prevalence was determined by year and association of demographic variables with maternal GBS colonization was determined using logistic regression. RESULTS: Maternal GBS screening was less than 15% in each country, except Uruguay which screened greater than 65% of women. The final regression model examining maternal screening rates and demographic variables included the covariates ethnicity, maternal age group, education level and civil status. Countries with lower rates of maternal GBS screening had increased odds of neonatal sepsis [OR 23.3; 95% CI (15.2-35.9)] and pneumonia [OR 19.9; 95% CI (12.1-32.6)]. In Uruguay, GBS prevalence over the study period was 18.5%. Black women, older women and women without a primary education had higher rates of GBS colonization (21.3%, 20.4% and 21.9% respectively). CONCLUSIONS: Our study highlights the need for national policy and investments to increase maternal GBS screening and better understand the prevalence of maternal GBS colonization in Latin America. Further research on the burden of neonatal GBS disease within Latin America is needed to inform the introduction of a maternal GBS vaccine, when available.

Trichomonas vaginalis in Pregnancy: Patterns and Predictors of Testing, Infection, and Treatment.

OBJECTIVE: To identify factors associated with testing for and diagnosis of trichomoniasis in pregnancy and to describe patterns of treatment and tests of reinfection or persistence. METHODS: We conducted a retrospective cohort study of women who delivered from July 2016 to June 2018 at one institution. Testing for Trichomonas vaginalis infection was done by wet mount microscopy or by nucleic acid amplification testing for routine prenatal testing or symptomatic visits. Poisson regression was used to identify factors associated with testing for trichomoniasis and testing positive in pregnancy. Treatment and re-testing patterns also were assessed. RESULTS: Among 3,265 pregnant women, 2,489 (76%) were tested for T vaginalis infection. Of the total sample, 1,808 (55%) were tested by wet mount microscopy, 1,661 (51%) by nucleic acid amplification testing, and 980 (30%) by both modalities. The sensitivity for microscopy compared with nucleic acid amplification testing was 26%, with a specificity of 99%. Factors associated with increased likelihood of being tested included younger age (adjusted risk ratio [aRR] 0.99, 95% CI 0.99-1.00) and bacterial vaginosis (aRR 1.17, 95% CI 1.01-1.37). Prevalence of trichomoniasis was 15% among those tested by any modality (wet mount or nucleic acid amplification testing). Risk factors for trichomoniasis included younger age (aRR 0.97, P<.01), being of black race (aRR 2.62, P<.01), abnormal vaginal discharge (aRR 1.45, P<.01), and chlamydia during the current pregnancy (aRR 1.70, P<.01). Women diagnosed by microscopy had a shorter time to treatment compared with those diagnosed by nucleic acid amplification testing. Most (75%) women with positive infections had a test of reinfection; 29% of these were positive. Bacterial vaginosis was associated with decreased risk of a positive test of reinfection. CONCLUSION: Although testing for and treatment of trichomoniasis during pregnancy is not routinely recommended, the high burden of infection among some pregnant women demonstrates a need to further understand patterns of T vaginalis testing and infection. Opportunities exist for improving timely treatment of trichomoniasis and test of reinfection.
