Risk-Factor Based Lead Screening and Correlation with Blood Lead Levels in Pregnancy.

OBJECTIVES: Lead exposure has devastating neurologic consequences for children and may begin in utero. The American College of Obstetricians and Gynecologists recommends prenatal lead screening using a risk factor-based approach rather than universal blood testing. The clinical utility of this approach has not been studied. We evaluated a risk-factor based questionnaire to detect elevated blood lead levels in pregnancy. METHODS: We performed a secondary analysis of a cohort of parturients enrolled to evaluate the association of lead with hypertensive disorders of pregnancy. We included participants in this analysis if they had a singleton pregnancy ≥ 34 weeks' gestation with blood lead levels recorded. Participants completed a lead risk factor survey modified for pregnancy. We defined elevated blood lead as ≥ 2 µg/dL, as this was the clinically reportable level. RESULTS: Of 102 participants enrolled in the cohort, 92 had blood lead measured as part of the study. The vast majority (78%) had 1 or more risk factor for elevated lead using the questionnaire yet none had clinical blood lead testing during routine visits. Only two participants (2.2%) had elevated blood lead levels. The questionnaire had high sensitivity but poor specificity for predicting detectable lead levels (sensitivity 100%, specificity 22%). CONCLUSIONS FOR PRACTICE: Prenatal risk-factor based lead screening appears underutilized in practice and does not adequately discriminate between those with and without elevated blood levels. Given the complexity of the risk factor-based approach and underutilization, the benefit and cost-effectiveness of universal lead testing should be further explored.

Strategies to improve postpartum glucose screening rates are needed.

AIMS: Women with gestational diabetes mellitus (GDM) require postpartum glucose screening, as they have a 70% lifetime risk of developing Type 2 diabetes mellitus. However, less than half complete postpartum screening. METHODS: We conducted a retrospective chart review of patients who delivered at our institution from 2001 to 2019. Inclusion criteria were patients with gestational diabetes who were at least 18 years old and had delivered an infant at >24 weeks of gestation. Our primary outcome was completion of postpartum gestational diabetes screening. RESULTS: The majority of patients (62%) did not complete screening. After adjusted risk ratio analyses, the only variables that remained significantly associated with an increased likelihood of completing screening were Asian race and having prenatal care at one particular community health center, which served a predominantly Asian population. CONCLUSIONS: This community health center protocol for scheduling patients with GDM that complied with recommendations for postpartum care, indicating that evidence-based methods can improve maternal health.

Lead exposure and association with angiogenic factors and hypertensive disorders of pregnancy.

OBJECTIVES: Lead exposure has been associated with hypertensive disorders of pregnancy. Angiogenic factors, including soluble fms-like tyrosine kinase 1 (sFlt1) and placental growth factor (PlGF), are aberrant in preeclampsia, but have not been correlated with lead levels. We evaluated the association of lead exposure with angiogenic factors. STUDY DESIGN: This cross sectional study utilized a convenience sample of singleton pregnancies ≥34 weeks' gestation. Blood lead and angiogenic factors were measured before delivery; bone lead was measured postpartum. We dichotomized bone and blood lead into the top tertile versus the bottom tertiles and used log-binomial regression to assess the association between lead and a high angiogenic ratio. MAIN OUTCOME MEASURES: The outcomes were high sFlt1 to PlGF ratio and development of a hypertensive disorder of pregnancy. RESULTS: We enrolled 102 participants, of whom 98 had at least one lead measurement and an angiogenic factor result. Median bone lead was 3.8 ug/g (2.0 - 6.6) and median blood lead was 0.2 ug/dL (0.2 - 0.4). Incidence of hypertensive disorders of pregnancy was 31%. When comparing the highest tertile of bone lead to the bottom two tertiles, there was no association with a high sFlt1/PlGF ratio or hypertensive disorders of pregnancy. Similar results were observed for the exposure of blood lead. CONCLUSIONS: Lead exposure was not an important contributor to an elevated angiogenic factor ratio or hypertensive disorders of pregnancy in our U.S. POPULATION: However, lead exposure was modest in our population and we cannot exclude a relationship with hypertensive disorders of pregnancy.

Optimizing Perioperative Pain Control After Ambulatory Urogynecologic Surgery.

OBJECTIVES: The objective of this study was to determine the impact of a multimodal protocol on opiate use and postoperative pain after ambulatory urogynecologic surgery. METHODS: This was a retrospective cohort study comparing ambulatory urogynecologic surgery patients treated under a standard perioperative pain protocol with those treated under a multimodal perioperative pain protocol. The multimodal protocol consisted of preoperative gabapentin and acetaminophen and postoperative scheduled doses of acetaminophen and nonsteroidal anti-inflammatory drugs. Pain scores were obtained from nursing records and assessed on the Numeric Rating Scale 11 per hospital protocol. All opioid dosages were converted into morphine milligram equivalents using standardized conversion tables. RESULTS: We treated 109 patients under the standard protocol and 112 under the multimodal protocol. Patients had similar baseline characteristics. Overall, a minority of patients (39%) used postoperative opioids; this was similar in the 2 groups (P=0.45). The 2 groups also were similar with regard to the total postoperative morphine milligram equivalents (P=0.35). Postoperatively, patients treated under the standard protocol had higher mean pain scores (2.2 vs 1.4, P=0.002). Patients treated under the standard protocol were also significantly more likely to report postoperative pain (69%) than those treated under the multimodal protocol (52%; P=0.01), and the multimodal protocol was associated with a 25% lower risk of postoperative pain (risk ratio, 0.75; 95% confidence interval, 0.60-0.94) than the standard protocol. CONCLUSIONS: Patients infrequently use opiates after ambulatory urogynecologic surgery. The use of a multimodal pain protocol was associated with lower pain scores, and patients in a multimodal pain protocol were more likely to report no pain.

Survey of Postoperative Activity Guidelines After Minimally Invasive Gynecologic and Pelvic Reconstructive Surgery.

OBJECTIVES: Most surgeons recommend restriction of activities after minimally invasive gynecologic and pelvic reconstructive surgery. The goal of this study was to identify and assess the postoperative guidelines gynecologists and urogynecologists provide their patients. METHODS: This was a cross-sectional study of physicians at a national gynecology conference in March 2018. Respondents were asked to answer questions about the typical postoperative recommendations they provide patients after gynecologic surgery as well as their postoperative prescribing habits. RESULTS: There were 418 attendees, and 135 (32%) eligible physicians completed the survey. Of respondents, 87% were specialists in female pelvic medicine and reconstructive surgery. Most respondents (61%) were in academic practice. Most respondents (82%-86%) recommended specific postoperative lifting restrictions, and 49% to 52% recommended limiting lifting to a maximum of 10 lb after surgery with some variation depending on the surgical procedure performed. Many respondents (42%-56% depending on the surgical procedure) recommended that patients wait at least 2 weeks before returning to sedentary work. Male respondents and those who were in practice for more than 10 years recommended that patients return to work sooner compared with those who were in practice less than 10 years. Male respondents prescribed fewer opioids to patients after vaginal hysterectomy (P = 0.04) and vaginal prolapse repair (P = 0.03) compared with female respondents. CONCLUSIONS: After minimally invasive gynecologic or pelvic reconstructive surgery, providers recommend a wide range of postoperative restrictions and prescribe significantly different quantities of opioids during the postoperative period. This study highlights some of the recommendations with the greatest variability.

Local recurrence after breast-conserving therapy for phyllodes tumors: A 15-year retrospective review.

There are few data on the long-term outcomes of patients with phyllodes tumors following breast-conserving surgery with or without radiation therapy (RT). We reviewed 69 patients diagnosed from 2000 to 2015 with surgical specimens available for central pathology assessment for outcome in relation to histopathologic subtype, margin width, and utilization of RT. Median follow-up was 63 months (interquartile range, 35-131 months). Forty-eight patients had benign, 13 borderline, and eight malignant phyllodes tumors, with local recurrence rates of 4%, 0%, and 38%, respectively (P ≤ .04 comparing malignant lesions to both benign and borderline lesions). None of the eight patients who received RT suffered a local recurrence. Two of the 26 (8%) patients with benign phyllodes tumors who did not receive RT with margins that were positive or <1 mm had local recurrence, compared to none of 18 patients with margins 1 mm or wider who did not receive RT. The one patient with a malignant phyllodes tumor who did not receive RT with margins that were positive or <1 mm did not locally recur, while both patients with margins 10 mm or wider who did not receive RT had local recurrence. One patient with a malignant phyllodes tumor developed distant recurrence following local recurrence. Phyllodes histologic type and margin width were both associated with the risk of local recurrence following breast-conserving surgery without RT, though the number of events and patients was too small to show these trends were statistically significant.

Community Health Center Engagement and Training During Obstetrics and Gynecology Residency.

BACKGROUND: Community health centers (CHCs) and federally qualified health centers (FQHCs) are critical health care access points for medically underserved areas in the United States. They also provide opportunities for residents to learn about health system challenges, including workforce shortages, social determinants of health, and health equity. OBJECTIVE: We sought to describe current obstetrics and gynecology (OB-GYN) resident engagement and training in community health settings. METHODS: We conducted a website review and survey to identify the prevalence and types of OB-GYN resident exposure to CHCs, including FQHCs. We reviewed 241 program websites to identify community health electives or rotations. We then surveyed program administrators regarding departmental affiliations with CHCs, types of resident involvement, and barriers to resident rotations at CHCs. RESULTS: The website review revealed that 18% (44 of 241) of programs offered a community health rotation. Of the 241 programs surveyed, 78 program administrators responded (32%). Forty-three programs (55%) had at least 1 affiliated CHC, and 34 programs (44%) allowed residents to rotate at a CHC. The most common barrier to resident rotations at a CHC was inadequate resident coverage of hospital-based clinical responsibilities. Respondents reported that among 782 graduating residents in the 2016-2017 and 2017-2018 academic years, 76 (10%) planned to pursue a position at a CHC. CONCLUSIONS: According to their websites, a small percentage of US OB-GYN residency programs offered a CHC rotation. Of programs responding to a survey on the topic, less than half offered CHC rotations and less than 1 in 10 residents planned to work in CHCs after graduation.

Applying the E Value to Assess the Robustness of Epidemiologic Fields of Inquiry to Unmeasured Confounding.

We explored the use of the E value to gauge the robustness of fields of epidemiologic inquiry to unmeasured confounding. We surveyed nutritional and air pollution studies that found statistically significant associations between exposures and incident outcomes. For 100 studies in each field, we extracted adjusted relative effect estimates and associated confidence intervals. We inverted estimates where necessary so that all effects were greater than 1. We calculated E values for both the effect estimate and the lower limit of the 95% confidence interval. Nutritional studies were smaller than air pollution studies (median participants per study, 40,652 vs. 72,460). More than 90% of nutritional studies categorized the exposure, whereas 89% of air pollution studies analyzed the exposure as a continuous variable. The median relative effect was 1.33 in nutrition and 1.16 in air pollution. The corresponding median E values for the estimates were 2.00 and 1.59, respectively. E values for the 95% confidence intervals had median values of 1.39 and 1.26, respectively. Little to moderate unmeasured confounding could explain away most observed associations. The E value is necessarily larger for smaller studies that reach statistical significance, making cross-field comparison difficult. The E value for the 95% confidence interval might be a more useful measure in reports of epidemiologic observational studies.
