CONTEXT/BACKGROUND:Accelerating evidence of endocrine-related morbidity has raised alarm about the ubiquitous use of phthalates in the human environment, but studies have not directly evaluated mortality in relation to these exposures. OBJECTIVES/OBJECTIVE:To evaluate associations of phthalate exposure with mortality, and quantify attributable mortality and lost economic productivity in 2013-4 among 55-64 year olds. DESIGN/METHODS:This nationally representative cohort study included 5303 adults aged 20 years or older who participated in the US National Health and Nutrition Examination Survey 2001-2010 and provided urine samples for phthalate metabolite measurements. Participants were linked to mortality data from survey date through December 31, 2015. Data analyses were conducted in July 2020. MAIN OUTCOME MEASURES/METHODS:Mortality from all causes, cardiovascular disease, and cancer. RESULTS:Multivariable models identified increased mortality in relation to high-molecular weight (HMW) phthalate metabolites, especially those of di-2-ethylhexylphthalate (DEHP). Hazard ratios (HR) for continuous HMW and DEHP metabolites were 1.14 (95% CI 1.06-1.23) and 1.10 (95% CI 1.03-1.19), respectively, with consistently higher mortality in the third tertile (1.48, 95% CI 1.19-1.86; and 1.42, 95% CI 1.13-1.78). Cardiovascular mortality was significantly increased in relation to a prominent DEHP metabolite, mono-(2-ethyl-5-oxohexyl)phthalate. Extrapolating to the population of 55-64 year old Americans, we identified 90,761-107,283 attributable deaths and $39.9-47.1 billion in lost economic productivity. CONCLUSIONS:In a nationally representative sample, phthalate exposures were associated with all-cause and cardiovascular mortality, with societal costs approximating $39 billion/year or more. While further studies are needed to corroborate observations and identify mechanisms, regulatory action is urgently needed.

Fetal exposure to phthalates and bisphenols could be associated with kidney function. We aim to assess the association between maternal urine concentrations of phthalates and bisphenols during pregnancy and kidney function and size during childhood. In 1366 pregnant women from a prospective population-based cohort, we measured urine concentrations of phthalates, more specifically phthalic acid and metabolites of low molecular weight phthalates (LMWP) and high molecular weight phthalates (HMWP), with its subgroups of di-2-ethylhexylphthalate (DEHP) and di-n-octylphthalate (DNOP) metabolites, and bisphenol A, S and F during first, second and third trimester. We explored three methods of adjustment for maternal hydration status: creatinine standardization, covariate adjustment for creatinine and covariate-adjusted creatinine standardization plus covariate adjustment. We measured kidney size, calculated estimated glomerular filtration rate (eGFR) and the albumin/creatinine ratio in urine and assessed microalbuminuria at 6 years old. When applying creatinine standardization, we found some associations of higher maternal second trimester urine phthalic acid and overall mean phthalic acid and LMWP concentrations with higher eGFR. These associations were lessened when applying other methods of creatinine adjustment. The associations found when we applied the covariate adjustment for creatinine method were also lessened when applying other methods of creatinine adjustment. Only the association of higher second trimester phthalic acid maternal urine concentrations with higher eGFR at 6 years old remained significant irrespective of the method of creatinine adjustment. There were no consistent associations of maternal bisphenol A, S and F urine concentrations with childhood kidney function. There were no associations of maternal phthalate or bisphenol urine concentrations with kidney volume in children at 6 years old. Concluding, no consistent associations of maternal phthalate or bisphenol urine concentrations with childhood kidney function or volume could be found. Furthermore, the method of adjusting maternal urine phthalate and bisphenol concentrations for urinary dilution had a substantial effect on the associations with childhood kidney function, as it changed the conclusions about the directionality of the associations. Future studies including maternal kidney function are needed to further elucidate these association in humans.

A growing body of literature indicates that Latinx immigrant families are adversely affected by restrictive immigration policies and anti-immigrant rhetoric. Little is known about how educators working with Latinx immigrant communities in restrictive immigration climates fare. Using mixed-methods, this study sought to better understand how the work and well-being of educators working with Latinx immigrant communities can be affected by a charged immigration climate. Using survey data from 88 educators in New York City and interview data from 17 educators in New York, California, Arizona, and Texas, we find that efficacy to help distressed children varies among educators. School-based resources such as clear, proactive organizational communication, supportive leadership that is attune to the needs and strengths of the immigrant community and communal coping are associated with educator efficacy to address student distress. Qualitative findings triangulate quantitative data; absent structural supports, educators working in Latinx immigrant communities can be adversely impacted by a charged immigration climate due to increases in work complexity, their own immigration-related worry, and experiences of vicarious racism. Recommendations for supports for educators working with Latinx immigrant communities are discussed.

INTRODUCTION/BACKGROUND:The COVID-19 Healthcare Personnel Study (CHPS) was designed to assess adverse short-term and long-term physical and mental health impacts of the coronavirus disease-2019 (COVID-19) pandemic on New York's physicians, nurse practitioners, and physician assistants. METHODS:Online population-based survey. Survey-weighted descriptive results, frequencies, proportions, and means, with 95% confidence intervals (95% CI). Odds ratios (ORs) for association. RESULTS:Over half (51.5%; 95% CI: 49.1, 54.0) of respondents worked directly with COVID-19 patients; 27.3% (95% CI: 22.5, 32.2) tested positive. The majority (57.6%; 95% CI: 55.2, 60.0) reported a negative impact on their mental health. Negative mental health was associated with COVID-19 symptoms (OR=1.7, 95% CI: 1.3, 2.1) and redeployment to unfamiliar functions (OR=1.3, 95% CI: 1.1, 1.6). CONCLUSIONS:A majority of New York health care providers treated COVID-19 patients and reported a negative impact on their mental health.

RATIONALE/BACKGROUND:Asthma and obesity often co-occur. It has been hypothesized that asthma may contribute to childhood obesity onset. OBJECTIVES/OBJECTIVE:To determine if childhood asthma is associated with incident obesity and examine the role of asthma medication in this association. METHODS:We studied 8,716 children between ages 6 and 18.5 years who were nonobese at study entry participating in 18 US cohorts of the Environmental influences on Child Health Outcomes program (among 7,299 children with complete covariate data mean [SD] study entry age = 7.2 [1.6] years and follow up = 5.3 [3.1] years). MEASUREMENTS AND MAIN RESULTS/RESULTS:We defined asthma based on caregiver report of provider diagnosis. Incident obesity was defined as the first documented body mass index ≥95th percentile for age and sex following asthma status ascertainment. Over the study period, 26% of children had an asthma diagnosis and 11% developed obesity. Cox proportional hazards models with sex-specific baseline hazards were fitted to assess the association of asthma diagnosis with obesity incidence. Children with asthma had a 23% (95% confidence intervals [CI] = 4, 44) higher risk for subsequently developing obesity compared with those without asthma. A novel mediation analysis was also conducted to decompose the total asthma effect on obesity into pathways mediated and not mediated by asthma medication use. Use of asthma medication attenuated the total estimated effect of asthma on obesity by 64% (excess hazard ratios = 0.64; 95% CI = -1.05, -0.23). CONCLUSIONS:This nationwide study supports the hypothesis that childhood asthma is associated with later risk of obesity. Asthma medication may reduce this association and merits further investigation as a potential strategy for obesity prevention among children with asthma.

OBJECTIVE:To estimate difference in population-level glycemic control and the emergence of diabetes complications given a theoretical scenario in which non-White youth and young adults (YYA) with type 1 diabetes (T1D) receive and follow an equivalent distribution of diabetes treatment regimens as non-Hispanic White YYA. RESEARCH DESIGN AND METHODS/METHODS:) and the prevalence of diabetes complications for non-White YYA. RESULTS:< 0.05), although the low proportion of YYA who developed complications limited statistical power for risk estimations. CONCLUSIONS:Mathematically modeling an equalized distribution of T1D self-management tools and technology accounted for part of but not all disparities in glycemic control between non-White and White YYA, underscoring the complexity of race and ethnicity-based health inequity.

Colombia has experienced a significant increase in the incidence of HIV in the past decade attributed to the alarming rise of heroin injection. However, there is limited information about the level of HIV knowledge and the perception of risk among people who inject drugs (PWIDs) in Latin America. Further data is needed to optimally inform HIV prevention efforts in the region. The present study explores the level of HIV knowledge and risk perception, and their potential association with risk practices among PWIDs in Colombia. The survey instrument included the 18-item HIV Knowledge Questionnaire and the Risk Assessment Battery. Among the 190 respondents who completed the survey, approximately half demonstrated a limited knowledge of HIV (51.1%, n = 97). Misconceptions regarding the mechanisms of HIV transmission and the usefulness of female condoms were common. Homelessness was associated with limited HIV knowledge (p =.006, OR 2.62 IC 95% 1.31"“5.25). Lastly, HIV knowledge was associated with safer injection behaviors, but was not related to safe sexual practices. Perceived risk of HIV exposure was not related to the level of HIV knowledge, drug-related, or sexual risk behaviors. Overall, our results indicate that misconceptions about the mechanisms of HIV transmission persist among PWIDs in Colombia, particularly among unstably housed respondents. Further efforts are needed to address social determinants of health, including housing access, among this vulnerable population to reduce the risks of HIV exposure.

INTRODUCTION: The pulmonary embolism severity index (PESI) score is a well-known and validated clinical tool, utilized to predict 30-day mortality in patients with pulmonary embolism (PE). It is used to identify low-risk individuals (PESI < =85) who can be safely started on novel oral anticoagulation agents (NOAC) and discharged from the Emergency Department (ED). After calculating the PESI score in all patients admitted for PE within a 3-year period at a community hospital, this study first estimated the fraction of low-risk patients who ended up getting admitted. Additionally, this study compared the prevalence of right heart strain (RHS), incidence of bleeding events, and mortality rates between the low-risk and high-risk (PESI >85) cohorts.
METHOD(S): This study is a retrospective chart review of patients admitted with a primary diagnosis of PE to Mercy Fitzgerald Hospital from January 2018 to March 2021. The Fisher test was used to compare odds ratios (OR) of RHS on initial CT angiogram of the chest, bleeding events after initiation of the anticoagulation (drop in hemoglobin > 2 g/dL, positive hemoccult status, episodes of overt bleeding), and death rates between low-risk and high-risk groups. PRISM statistical software was used for statistical analysis.
RESULT(S): 211 patients were included in this study. 102 (48.3%) patients were categorized as low-risk and 109 (51.7%) as high-risk. RHS was present in 16 patients of the low-risk group (2 of which had saddle PE) versus 41 in the high-risk group (OR 0.39, CI [0.2-0.76], p 0.005). Bleeding after initiation of anticoagulation was observed in 2 patients in the low-risk versus 5 patients in the high-risk group (OR 0.42, CI [0.08-2], p 0.45). None of the patients in the low-risk group died during the admission compared to 6 patients from the high-risk group (OR non reported, CI [0-0.74], p 0.03).
CONCLUSION(S): When factoring in patients with RHS on initial imaging, 40.7% of the patients hospitalized for PE potentially could have been discharged safely for outpatient management based on this study. The patients who were identified as high risk had a higher occurrence of RHS and had significantly higher mortality compared to the low-risk group. The rate of bleeding events after initiation of anticoagulation among both groups was not statistically different
