RESUMO
Persistent endocrine disrupting chemicals (EDCs) can dysregulate the stress response. We evaluated associations between persistent EDCs and perceived stress among participants from the Study of Environment, Lifestyle and Fibroids (n=1,394), a prospective cohort study of Black women. Participants completed the Perceived Stress Scale (PSS-4) at baseline, and every 20 months through 60 months (range of scores: 0-16); higher scores indicated higher stress. EDCs, including per- and polyfluoroalkyl substances (PFAS), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and organochlorine pesticides, were quantified in plasma samples at baseline. We fit Bayesian Kernel Machine Regression (BKMR) and linear mixed effects models to estimate associations of EDCs (as a mixture and individually) with PSS-4 scores at baseline and at each follow-up visit, respectively. Increasing percentiles of the mixture were not strongly associated with PSS-4 scores at baseline, and no interactions were observed among EDCs. Several individual EDCs (e.g., PFDA, PCB 118, PBDE 99) were associated with higher PSS-4 scores at baseline or follow-up, while other EDCs (e.g., PCB 138/158) were associated with lower PSS-4 scores at baseline or follow-up. The directionality of associations for individual EDCs was inconsistent across follow-up visits. In conclusion, specific EDCs may be associated with perceived stress in Black women.
RESUMO
Chemical hair straighteners ("relaxers") are used by millions of North Americans, particularly women of color. Hair relaxers may contain endocrine-disrupting compounds, which can harm fertility. We evaluated the association between hair relaxer use and fecundability among 11,274 participants from Pregnancy Study Online (PRESTO), a North American preconception cohort study. During 2014-2022, participants completed a baseline questionnaire in which they reported their history of relaxer use and completed follow-up questionnaires every 8 weeks for 12 months or until pregnancy, whichever came first. We used multivariable-adjusted proportional probabilities regression models to estimate fecundability ratios (FRs) and 95% confidence intervals (CIs). Relative to never use, fecundability was lower among current (FR = 0.81, 95% CI: 0.64, 1.03) and former (FR = 0.89, 95% CI: 0.81, 0.98) users of hair relaxers. FRs for first use of hair relaxers at ages <10, 10-19, and ≥20 years were 0.73 (95% CI: 0.55, 0.96), 0.93 (95% CI: 0.83, 1.04), and 0.85 (95% CI: 0.74, 0.98), respectively. Fecundability was lowest among those with longer durations of use (≥10 years vs. never: FR = 0.71, 95% CI: 0.54, 0.91) and more frequent use (≥5 times/year vs. never: FR = 0.82, 95% CI: 0.60, 1.11), but associations were nonmonotonic. In this preconception cohort study, use of chemical hair straighteners was associated with slightly reduced fecundability.

BACKGROUND: Uterine leiomyomata (fibroids) are common, benign neoplasms that contribute substantially to gynecologic morbidity. Some existing epidemiologic studies indicate that cigarette smoking is associated with lower uterine leiomyomata risk. However, no prospective studies have systematically screened an entire study population for uterine leiomyomata using transvaginal ultrasound or evaluated the association between cigarette smoking and uterine leiomyomata growth. OBJECTIVE: This study aimed to examine the association between cigarette smoking and uterine leiomyomata incidence and growth in a prospective ultrasound study. STUDY DESIGN: We enrolled 1693 residents from the Detroit metropolitan area into the Study of Environment, Lifestyle, and Fibroids during 2010 to 2012. Eligible participants were aged 23 to 34 years, had an intact uterus but no previous diagnosis of uterine leiomyomata, and self-identified as Black or African American. We invited participants to complete a baseline visit and 4 follow-up visits over approximately 10 years. At each visit, we used transvaginal ultrasound to assess uterine leiomyomata incidence and growth. Participants provided extensive self-reported data throughout follow-up including exposures to active and passive cigarette smoking in adulthood. We excluded participants who did not return for any follow-up visits (n=76; 4%). We fit Cox proportional hazards regression models to estimate hazard ratios and 95% confidence intervals for the association between time-varying smoking history and incidence rates of uterine leiomyomata. We fit linear mixed models to estimate the percentage difference and 95% confidence intervals for the association between smoking history and uterine leiomyomata growth. We adjusted for sociodemographic, lifestyle, and reproductive factors. We interpreted our results based on magnitude and precision rather than binary significance testing. RESULTS: Among 1252 participants without ultrasound evidence of uterine leiomyomata at baseline, uterine leiomyomata were detected in 394 participants (31%) during follow-up. Current cigarette smoking was associated with a lower uterine leiomyomata incidence rate (hazard ratio, 0.67; 95% confidence interval, 0.49-0.92). Associations were stronger among participants who had smoked for longer durations (≥15 years vs never: hazard ratio, 0.49; 95% confidence interval, 0.25-0.95). The hazard ratio for former smokers was 0.78 (95% confidence interval, 0.50-1.20). Among never smokers, the hazard ratio for current passive smoke exposure was 0.84 (95% confidence interval, 0.65-1.07). Uterine leiomyomata growth was not appreciably associated with current (percent difference, -3%; 95% confidence interval, -13% to 8%) or former (percent difference, -9%; 95% confidence interval, -22% to 6%) smoking. CONCLUSION: We provide evidence from a prospective ultrasound study that cigarette smoking is associated with lower uterine leiomyomata incidence.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals used in commercial and consumer goods. Black women are underrepresented in studies of PFAS exposure. METHODS: We performed a cross-sectional analysis of correlates of plasma PFAS concentrations among 1499 Black women aged 23-35 participating in the Study of Environment, Lifestyle, and Fibroids (SELF), a Detroit-based cohort study. At baseline (2010-2012), participants provided questionnaire data on socio-demographics; behaviors; diet; and menstrual, contraceptive, and reproductive histories. Using mass spectrometry in non-fasting plasma samples collected at enrollment, we quantified several PFAS, including perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), perfluorononanoate (PFNA), perfluorodecanoate (PFDA), perfluoroundecanoate (PFUnDA), and 2-N-methyl-perfluorooctane sulfonamido acetate (MeFOSAA). We used linear regression to calculate percentage differences (%D) and 95 % confidence intervals (CIs) for associations between selected correlates and PFAS concentrations, adjusting for all other correlates. RESULTS: PFHxS, PFOS, PFOA, and PFNA were detected in ≥97 % of women; PFDA in 86 %; MeFOSAA in 70 %; and PFUnDA in 52 %. Age, income, education, and intakes of water, alcohol, and seafood were positively associated with several PFAS. Current smoking was positively associated with MeFOSAA. Body mass index was inversely associated with most PFAS, except PFHxS. Strong inverse associations (%D; 95 % CI) were observed between parity (≥3 vs. 0 births) and PFHxS (-34.7; -43.0, -25.1) and PFOA (-33.1; -39.2, -26.3); breastfeeding duration (≥6 months vs. nulliparous) and PFOA (-31.1; -37.8, -23.7), PFHxS (-24.2; -34.5, -12.3), and PFOS (-18.4; -28.3, -7.1); recent birth (<2 years ago vs. nulliparous) and PFOA (-33.1; -39.6, -25.8), PFHxS (-29.3; -39.0, -18.1), PFNA (-25.2; -32.7, -16.8), and PFOS (-18.3; -28.3, -6.9); and intensity of menstrual bleed (heavy vs. light) and PFHxS (-18.8; -28.3, -8.2), PFOS (-16.4; -24.9, -7.1), PFNA (-10.5; -17.8, -2.6), and PFOA (-10.0; -17.2, -2.1). Current use of depot medroxyprogesterone acetate (DMPA) was positively associated with PFOS (20.2; 1.4, 42.5), PFOA (16.2; 1.5, 33.0), and PFNA (15.3; 0.4, 32.4). CONCLUSIONS: Reproductive factors that influence PFAS elimination showed strong associations with several PFAS (reduced concentrations with parity, recent birth, lactation, heavy menstrual bleeding; increased concentrations with DMPA use).

OBJECTIVE: To determine the likelihood of using formal and informal mental health services among college students according to prior history of depression diagnosis and presence of depression symptoms. PARTICIPANTS: College students from 79 universities in the U.S. and Canada who participated in the Healthy Minds Study, 2018-2019. METHODS: Odds ratios and 95% confidence intervals via logistic regression were estimated for the likelihood of using informal and formal mental health services stratified by depression diagnosis and severity of depression symptoms and further stratified by race/ethnicity. RESULTS: We report increased odds of using formal mental health services with increasing depression severity symptoms and increased odds of using formal mental health services among students without a clinical depression diagnosis. The odds of service utilization varied by race/ethnicity. CONCLUSIONS: The likelihood of seeking mental health services differs depending on the history of formal depression diagnosis, current symptoms, and race/ethnicity among college students.
RESUMO
INTRODUCTION: The impact of COVID-19 on the placenta is poorly described, particularly among minority women. MATERIALS AND METHODS: This is a retrospective case-control study. Micro- and macroscopic placental pathologic findings were compared for 15 COVID-19 positive and 36 negative mothers. Cases and controls were frequency matched on gestational age, race, maternal comorbidities, and delivery type. Data from the electronic medical record were supplemented with independent review of microscopic slides. RESULTS: Placentas from cases and controls were similar except the median distance from the site of the cord insertion to the nearest disk margin was statistically significantly shorter among placentas from COVID-19 positive cases (3.5 versus 6.0 cm, p = 0.006). Case status was not associated with an increased risk of placental pathologies. CONCLUSION: There are few pathologic differences between placentas of COVID-19 positive and negative mothers. Additional studies are needed to investigate the role of timing of infection.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are endocrine-disrupting chemicals with neurotoxic properties. PFAS have been associated with depressive symptoms among women in some studies, but little research has evaluated the effects of PFAS mixtures. Further, no study has investigated interactions of PFAS-depression associations by perceived stress, which has been shown to modify the effects of PFAS on other health outcomes. OBJECTIVE: In a prospective cohort study of reproductive-aged Black women, we investigated associations between PFAS and depressive symptoms and the extent to which perceived stress modified these associations. METHODS: We analyzed data from 1499 participants (23-35 years) in the Study of Environment, Lifestyle, and Fibroids. We quantified concentrations of nine PFAS in baseline plasma samples using online solid-phase extraction-liquid chromatography-isotope dilution tandem mass spectrometry. Participants reported perceived stress via the Perceived Stress Scale (PSS-4; range = 0-16) at baseline and depressive symptoms via the Center for Epidemiologic Studies Depression Scale (CESD; range = 0-44) at the 20-month follow-up visit. We used Bayesian Kernel Machine Regression to estimate associations between PFAS concentrations, individually and as a mixture, and depressive symptoms, and to assess effect modification by PSS-4 scores, adjusting for confounders. RESULTS: Baseline perfluorodecanoic acid concentrations were associated with greater depressive symptoms at the 20-month follow-up, but associations for other PFAS were null. The PFAS were not associated with depressive symptoms when evaluated as a mixture. The association between the 90th percentile (vs. 50th percentile) of the PFAS mixture with CES-D scores was null at the 10th (ß = 0.03; 95 % CrI = 0.20, 0.25), 50th (ß = 0.02; 95 % CrI = -0.16, 0.19), and 90th (ß = 0.01; 95 % CrI = 0.18, 0.20) percentiles of PSS-4 scores, suggesting perceived stress did not modify the PFAS mixture. CONCLUSION: In this prospective cohort study, PFAS concentrations-assessed individually or as a mixture-were not appreciably associated with depressive symptoms, and there was no evidence of effect modification by perceived stress.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are endocrine-disrupting chemicals used in commercial and consumer products. OBJECTIVE: We evaluated PFAS exposure in relation to incidence and growth of uterine leiomyomata (UL), hormone-dependent neoplasms that are associated with severe gynecologic morbidity. METHODS: We studied 1158 participants in the Study of Environment, Lifestyle, and Fibroids, a Detroit-based prospective cohort study of Black females aged 23-35 years at enrollment (2010-2012). At enrollment and four subsequent visits during 10 years of follow-up, participants attended in-person clinic visits, completed questionnaires, provided non-fasting blood samples, and underwent ultrasound for UL detection. We quantified 7 PFAS in baseline plasma samples using mass spectrometry. We used Cox regression and probit Bayesian kernel machine regression to estimate individual and joint effects of PFAS on UL incidence. We fit linear mixed models to estimate effects of individual PFAS on UL growth. We stratified by parity, an important route of PFAS elimination and determinant of UL. RESULTS: In individual PFAS analyses, we observed inverse associations for perfluorodecanoate (PFDA; ≥0.3 vs. <0.2 ng/ml: hazard ratio [HR] = 0.74; 95% confidence interval [CI]: 0.54-1.00) and perfluoroundecanoate (detected vs. non-detected: HR = 0.78; 95% CI: 0.61-1.01) and a weak positive association for perfluorohexane sulfonate (≥1 vs. <0.6 ng/ml: HR = 1.17; 95% CI: 0.85-1.61), while perfluorooctane sulfonate, perfluorooctanoate, perfluorononanoate (PFNA), and 2-N-methyl-perfluorooctane sulfonamido acetate (MeFOSAA) showed little association with UL incidence. The PFAS mixture was inversely associated with UL incidence, a finding driven by MeFOSAA and PFDA; however, PFNA was positively associated with UL incidence. The inverse association for PFDA and positive association for PFNA were stronger among nulliparous participants. Most PFAS showed slight inverse associations with UL growth. IMPACT STATEMENT: In this prospective ultrasound study of 1158 Black females aged 23-35 years at enrollment, we conducted a mixtures analysis to account for co-pollutant confounding and interaction. MeFOSAA and PFDA concentrations were inversely associated with UL incidence, while PFNA concentrations were positively associated with UL incidence. Concentrations of most PFAS were associated with decreased UL growth. This study contributes data to the sparse literature on PFAS exposure and UL development.
RESUMO
OBJECTIVES: Explore associations between eating disorders (EDs) and sleep duration and the impact of depression symptoms (DSs) in American college students. PARTICIPANTS: College students from 2018 to 2019 Healthy Minds Study. METHODS: Multivariate logistic regression evaluated associations between EDs (bulimia, anorexia, binge eating [BED]) and sleep duration. Stratified analyses assessed effect modification by DSs and gender. RESULTS: Students reporting any eating disorder had no greater risk of not recommended sleep duration during weekdays compared to those with no eating disorder history (Adjusted OR = 0.99, 95% CI: 0.89-1.13). However, subjects reporting BED were at greater risk of deficient sleep during weekends compared to those with no EDs (Adjusted OR = 1.26, 95% CI: 1.01-1.58). This association was not impacted by DSs. However, all EDs were associated with not-recommended sleep duration among those who identified as other gender identity in comparison to those with no EDs. CONCLUSION: Health educators should monitor academic performance in students with EDs for adequate sleep duration.
RESUMO
Vulvodynia, impacts up to 8% of women by age 40, and is hypothesized to manifest through an altered immune-inflammatory response. To test this hypothesis, we identified all women born in Sweden between 1973 and 1996 diagnosed with localized provoked vulvodynia (N76.3) and/or vaginismus (N94.2 or F52.5) between 2001 and 2018. We matched each case to two women from the same birth year with no vulvar pain ICD codes. As a proxy for immune dysfunction, we used Swedish Registry data to capture 1) immunodeficiencies, 2) single organ and multiorgan autoimmune conditions, 3) allergy and atopies, and 4) malignancies involving immune cells across the life course. Women with vulvodynia, vaginismus or both were more likely to experience immune deficiencies (OR 1.8, 95% CI, 1.2-2.8), single organ (OR 1.4, 95% CI, 1.2-1.6) and/or multi-organ (OR 1.6, 95% CI, 1.3-1.9) immune disorders, and allergy/atopy conditions (OR 1.7, 95% CI, 1.6-1.8) compared to controls. We observed greater risk with increasing numbers of unique immune related conditions (1 code: OR = 1.6, 95% CI, 1.5-1.7; 2 codes: OR = 2.4, 95% CI, 2.1-2.9; 3 or more codes: OR = 2.9, 1.6-5.4). These findings suggest that women with vulvodynia may have a more compromised immune system either at birth or at points across the life course than women with no vulvar pain history. PERSPECTIVE: Women with vulvodynia are substantially more likely to experience a spectrum of immune related conditions across the life course. These findings lend support to the hypothesis that chronic inflammation initiates the hyperinnervation that causes the debilitating pain in women with vulvodynia.

BACKGROUND: Residential green space can have positive physiological effects on human health through various mechanisms, including reducing stress and/or depression or facilitating physical activity. Although green space has been consistently associated with improved birth outcomes in several studies, there has been limited study of its effect on other reproductive outcomes, including fertility. OBJECTIVE: We examined associations between residential green space and fecundability, the per-cycle probability of conception. METHODS: We analyzed data from 8,563 female participants enrolled between 2013 and 2019 in Pregnancy Study Online (PRESTO), a prospective preconception cohort study of North American couples attempting conception. Participants completed a baseline questionnaire on sociodemographic, behavioral, and reproductive factors, and bimonthly follow-up questionnaires for up to 12 months to ascertain pregnancies. Using geocoded addresses, we calculated residential green space exposure using the Normalized Difference Vegetation Index (NDVI) within 50-, 100-, 250-, and 500-m buffers across multiple temporal scales: annual maximum, seasonal maximum, and seasonal mean. We used proportional probabilities regression models to estimate fecundability ratios (FRs), adjusting for sociodemographic, behavioral, and neighborhood characteristics. We also evaluated the extent to which associations were mediated by reductions in perceived stress or depressive symptoms and increased physical activity. RESULTS: When comparing the highest (≥0.8) with the lowest (<0.2) NDVI exposures within 50m, we observed positive associations in the annual maximum NDVI [FR: 1.33; 95% confidence interval (CI): 1.06, 1.67] and seasonal maximum NDVI (FR: 1.19; 95% CI: 1.00, 1.41) models, but little association in the seasonal mean NDVI models (FR: 0.98; 95% CI: 0.73, 1.30). Restricted cubic splines showed evidence of nonlinearity in this association. Results were similar across buffer distances. Perceived stress, depressive symptoms, and physical activity explained ≤5:0% of mediation across all NDVI metrics. DISCUSSION: In this cohort, greater residential green space was associated with a modest increase in fecundability. https://doi.org/10.1289/EHP10648.

BACKGROUND: Approximately 11% of 18-25 year-olds report thoughts of suicide. Additionally, suicide is the second leading cause of death in college student populations. We sought to evaluate the relationship between diagnosed mental health conditions and current symptoms of depression and/or anxiety and suicidality in the past year. METHODS: Healthy Minds Study (HMS) 2018-2019 data from 38,757 college students were analyzed. The PHQ-9, GAD-7, and prior mental health condition diagnoses were used to create a suicidality severity index and we determined how these associations varied by race/ethnicity, gender, and sexual orientation. We also assessed non-suicidal self-injury (NSSI) outcomes in the past year. RESULTS: Students with both a mental health condition diagnosis and current moderate/severe symptoms of depression and/or anxiety had a higher prevalence of NSSI, 10 times the odds (95% CI 9.4-11.5) of suicide ideation, 28 times the odds (95% CI 23.8-33.1) of suicide ideation, with planning or attempt, and 47 times the odds (95% CI 31.1-71.4) of suicide ideation, with planning and attempt, compared to students with none/minimal depression and/or anxiety symptoms and no mental health condition diagnosis. LIMITATIONS: We could not clinically confirm depression or anxiety diagnoses nor infer causality of associations in this cross-sectional study. Future longitudinal studies are needed to establish temporality. CONCLUSIONS: Mental health condition diagnoses and moderate/severe symptoms of depression and/or anxiety were strongly associated with suicidality among college students. These findings identify potential opportunities to further understand and address the mental health needs of college students.

Background: Hysterectomies can be performed with a minimally invasive surgical (MIS) approach or a laparotomic (abdominal) approach. The objective of this study was to assess any racial differences in the likelihood of having a planned MIS hysterectomy. Materials and Methods: A prospective cohort study of women undergoing hysterectomy at Henry Ford Health System was conducted where laparotomic and MIS approaches are available to all patients. All procedures were performed between October, 2015, and August, 2017. For this study, women were asked to report demographic and insurance information and complete validated questionnaires from 2 weeks before hysterectomy and up to six additional times in the year after hysterectomy. Clinical and operative characteristics were collected from electronic health records. Logistic regression and multinomial logistic regression models were applied to assess the association between race and the surgical approach. Results: Analyses included 235 White women and 196 Black women. Black women were less likely to have any MIS planned for their hysterectomy (odds ratio [OR] = 0.46, 95% confidence interval [CI] 0.3-0.71, p < 0.05), a laparoscopic hysterectomy (relative risk ratio [RRR] = 0.46, 95% CI 0.29-0.73, p < 0.05), or a vaginal hysterectomy (RRR = 0.45, 95% CI 0.25-0.81, p = 0.01) compared with White women. After adjusting for confounders, uterine weight and indication for surgery was fibroids, these racial differences did not remain statistically significant (MIS vs. abdominal [adjusted odds ratio {aOR} = 0.93, 95% CI 0.55-1.57, p = 0.79], laparoscopic vs. abdominal [adjusted relative risk ratio {aRRR} = 0.89, 95% CI 0.52-1.51, p = 0.54], and vaginal vs. abdominal [aRRR = 1.22, 95% CI 0.61-2.45, p = 0.58]). The associations were not confounded by the baseline survey data from standardized questionnaires on depression, financial distress, and satisfaction with their decision. Conclusions: Black women were not less likely than White women to have planned an MIS hysterectomy after controlling for important confounding variables. These results emphasize the importance of considering all important confounders when examining racial differences.

Clinical guidelines recommend statins for patients with atherosclerotic cardiovascular disease (ASCVD), but many remain untreated. The goal of this study was to assess the impact of statin use on recurrent major adverse cardiovascular events (MACE). This study used medical records and insurance claims from 4 health care systems in the United States. Eligible adults who survived an ASCVD hospitalization from September 2013 to September 2014 were followed for 1 year. A multivariable extended Cox model examined the outcome of time-to-first MACE, then a multivariable joint marginal model investigated the association between post-index statin use and nonfatal and fatal MACE. There were 8,168 subjects in this study; 3,866 filled a statin prescription ≤90 days before the index ASCVD event (47.33%) and 4,152 filled a statin prescription after the index ASCVD event (50.83%). These post-index statin users were younger, with more co-morbidities. There were 763 events (315/763, 41.3% terminal) experienced by 686 (8.4%) patients. The adjusted overall MACE risk reduction was 18% (HR 0.82, 95% CI 0.70 to 0.95, p = 0.007) and was more substantial in the first 180 days (HR 0.72, 95% CI 0.60 to 0.86, p <0.001). There was a nonsignificant 19% reduction in the number of nonfatal MACE (rate ratio 0.81, 95% CI 0.49 to 1.32, p = 0.394) and a 65% reduction in the risk of all-cause death (HR 0.35, 95% CI 0.22 to 0.56, p <0.001). In conclusion, we found a modest increase in statin use after an ASCVD event, with nearly half of the patients untreated. The primary benefit of statin use was protection against early death. Statin use had the greatest impact in the first 6 months after an ASCVD event; therefore, it is crucial for patients to quickly adhere to this therapy.

BACKGROUND: Metals may influence reproductive health, but few studies have investigated correlates of metal body burden among reproductive-aged women outside of pregnancy. Furthermore, while there is evidence of racial disparities in exposure to metals among U.S. women, there is limited research about correlates of metal body burden among Black women. OBJECTIVE: To identify correlates of whole blood metal concentrations among reproductive-aged Black women. METHODS: We analyzed cross-sectional data from a cohort of 1664 Black women aged 23-35 years in Detroit, Michigan, 2010-2012. We collected blood samples and questionnaire data. We measured concentrations of 17 metals in whole blood using inductively-coupled plasma-mass spectrometer-triple quadrupole and total mercury using Direct Mercury Analyzer-80. We used multivariable linear regression models to identify sociodemographic, environmental, reproductive, and dietary correlates of individual metal concentrations. RESULTS: In adjusted models, age was positively associated with multiple metals, including arsenic, cadmium, and mercury. Education and income were inversely associated with cadmium and lead. Current smoking was strongly, positively associated with cadmium and lead. Alcohol intake in the past year was positively associated with arsenic, barium, copper, lead, mercury, vanadium, and zinc. Having pumped gasoline in the past 24 h was positively associated with cadmium, chromium, and molybdenum. Having lived in an urban area for the majority of residence in Michigan was positively associated with arsenic, lead, and nickel. Higher water intake in the past year was positively associated with several metals, including lead. Fish intake in the past year was positively associated with arsenic, cesium, and mercury. We also observed associations with body mass index, season, and other environmental, reproductive, and dietary factors. SIGNIFICANCE: We identified potential sources of exposure to metals among reproductive-aged Black women. Our findings improve understanding of exposures to metals among non-pregnant reproductive-aged women, and can inform policies in support of reducing disparities in exposures. IMPACT STATEMENT: There are racial disparities in exposures to metals. We analyzed correlates of blood metal concentrations among reproductive-aged Black women in the Detroit, Michigan metropolitan area. We identified sociodemographic, anthropometric, lifestyle, environmental, reproductive, and dietary correlates of metal body burden. Age was positively associated with several metals. Education and income were inversely associated with cadmium and lead, indicating socioeconomic disparities. We identified potential exposure sources of metals among reproductive-aged Black women, including smoking, environmental tobacco smoke, pumping gasoline, living in an urban area, and intake of alcohol, water, fish, and rice.
RESUMO
PURPOSE: Patient-centered care promotes positive health outcomes in pediatrics. We created a provider-focused intervention and implemented it in a pragmatic clustered randomized controlled trial to improve health-related quality of life (HRQOL) among pediatric patients. METHODS: A one-time (1-1.5-hour) webinar focusing on patient-centered care and motivational interviewing, using obesity screening as an example, was developed. Pediatric providers were recruited and randomized to either intervention (webinar) or control (usual care) arms. All well-child visits to these providers for a period of up to 5 months following webinar completion (or study enrollment for controls) were identified, and these family/patients were invited to complete a survey to assess HRQOL postvisit. Reported outcomes were compared between intervention and control participants using clustered t-tests, chi-squared tests and multiple linear regression models. RESULTS: We recruited 20 providers (10 intervention, 10 control) to the study; 469 parents/guardians and 235 eligible children seeing these providers completed the postvisit survey. Parents/guardians of 8-12-year-old children in the intervention group reported higher school functioning compared to controls (83.5 vs 75.8; P=0.023). There were no other differences in children's HRQOL between intervention and control groups. CONCLUSIONS: A one-time, web-based provider intervention is feasible to implement in pediatrics. Modest evidence, requiring further study, indicates that instructing providers on patient-centered care in the well-child visit may improve aspects of pediatric HRQOL (ie, school functioning) compared to usual care. However, this was a brief intervention, with multiple outcomes tested and no evaluation of pre- and postintervention provider knowledge, thus additional study is needed.
RESUMO
BACKGROUND: The level of asymptomatic infection with SARS-CoV-2 could be substantial and among health care workers (HCWs) a source of continuing transmission of the virus to patients and co-workers. OBJECTIVES: Measure the period prevalence of SARS-CoV-2 PCR positivity and seroprevalence of SARS-CoV-2 IgG antibodies among a random sample of asymptomatic health system hospital-based health care workers (HCWs) 6½ -15½ weeks after 4/5/2020, the peak of the first surge of COVID-19 admissions. RESULTS: Of 524 eligible and consented participants from four metropolitan hospitals, nasopharyngeal swabs were obtained from 439 (83.8 %) and blood from 374 (71.4 %). Using PCR nucleic acid-based amplification (NAAT) methods, the period prevalence of SARS-CoV-2 infection was 0.23 % (95 % confidence interval (CI) 0.01 %-1.28 %; 1/439) from 5/21/20-7/16/20. The seroprevalence of SARS-CoV-2 IgG antibodies from June 17-July 24, 2020 was 2.41 % (95 % CI 1.27 %-4.51 %; 9/374). Those who were reactive were younger (median age 36 versus 44 years; p = 0.050), and those with self-reported Hispanic/Latino ethnicity had a higher seroprevalence (2/12 = 16.7 % versus 7/352 = 2.0 %; p = 0.051). There were no significant differences by sex, race, residence, hospital, unit or job type. The one employee who was found to be PCR test positive in this study was also reactive for IgG antibodies, tested 27 days later. CONCLUSIONS: The period prevalence of PCR positivity to SARS-CoV-2 and IgG seroprevalence was unexpectedly low in asymptomatic HCWs after a peak in COVID-19 admissions and the establishment of state and institutional infection control policies, suggesting that routine screening tests while community prevalence is relatively low would produce a minimal yield.

The burden of diabetes is higher in urban areas and among racial and ethnic minorities. The purpose of this research was to evaluate the effectiveness of extending a diabetes intervention program (DIP) by engaging a team, including a community health worker (CHW), to provide care for patients to meet glycemic control, specifically in a predominantly urban, minority patient population. The DIP enrolled diabetic patients from an internal medicine clinic. A CHW facilitated the collection of glucose meter readings. The CHW coached patients on glycemic control while the CHW's registered nurse partner titrated the patient's recommended insulin dose. Subsequent HbA1c values for participants were compared to those seen at the same clinic who were not enrolled. The DIP was deployed for nine months. One hundred forty-four patients were enrolled in the DIP and 348 patients constituted the comparator group. Ninety-three DIP participants had pre- and post-intervention HbA1c values and were compared to 348 non-DIP participants. Propensity score weighted adjusted analyses suggest that participants were more likely to reduce their HbA1c values by at least 1.0% and have HbA1c values of less than 8.0% (64 mmol/mol) than non-participants (adjusted odds ratio = aOR = 1.47, 95% CI 1.26-1.71, and aOR = 1.23, 95% CI 1.06-1.43, respectively). CHW coaches as part of a team in a clinical setting improved glycemic control in a predominantly urban, minority patient population.
RESUMO
PURPOSE: Previous reports indicate many women may not have a firm grasp on likely outcomes of different hysterectomy procedures. This study aimed to assess women's self-reported expectations of how they think their anatomy will change after hysterectomy. METHODS: Women scheduled for hysterectomy at a tertiary care hospital, for non-oncological reasons, reported their planned procedure type and the organs they understood would be removed 2 weeks prior to surgery. Patient reports and electronic medical records were reviewed, and kappa statistics (κ) were calculated to assess agreement for all women and within subgroups. RESULTS: Most of the 456 study participants (mean age: 48.02 ± 8.29 years) were either white/Caucasian (n=238, 52.2%) or African American (n=196, 43.0%). Among the 145 participants who reported a partial hysterectomy, 130 (89.7%) women indicated that their uterus would be removed and 52 (35.9%) reported that their cervix would be removed. Of those whose response was total hysterectomy (n=228), 208 (91.2%) participants reported their uterus would be removed and 143 (62.7%) reported their cervix would be removed. Among 144 women reporting a planned partial hysterectomy, only 15 (10.4%, κ=0.05) had a partial hysterectomy recorded in the electronic medical record. Among the 228 women who reported a planned total hysterectomy, 6.1% (κ=0.05) had a different procedure. While 125 participants reported planned ovary removal, only 93 (74.4%, κ=0.55) had an oophorectomy. Similarly, 290 participants reported planned fallopian tube removal, with 276 (95.2%, κ=0.06) having a salpingectomy. CONCLUSIONS: A considerable proportion of women undergoing hysterectomy do not accurately report the organs that are planned be removed during their hysterectomy. This work demonstrates the need to improve patient understanding of their clinical care and its implications.
