In this Ethics Rounds we present a conflict regarding discharge planning for a febrile infant in the emergency department. The physician believes discharge would be unsafe and would constitute a discharge against medical advice. The child's mother believes her son has been through an already extensive and painful evaluation and would prefer to monitor her well-appearing son closely at home with a safety plan and a next-day outpatient visit. Commentators assess this case from the perspective of best interest, harm-benefit, conflict management, and nondiscriminatory care principles and prioritize a high-quality informed consent process. They characterize the formalization of discharge against medical advice as problematic. Pediatricians, a pediatric resident, ethicists, an attorney, and mediator provide a range of perspectives to inform ethically justifiable options and conflict resolution practices.

Background: Community pharmacies offer a population-wide approach to scale opioid overdose prevention programs (OOPP). This qualitative study identified factors influencing implementation of New York State"™s OOPP to inform the uptake of naloxone dispensation in rural and small metro area pharmacies. Methods: In-person interviews were conducted among licensed retail, independent, or supermarket pharmacists (n = 60) in the mid-Hudson valley area of New York in high- and medium-overdose regions. The semi-structured 29-item survey captured attitudes and experiences related to pharmacy participation in naloxone dispensation. Results: Data revealed pharmacist support for naloxone dispensation. Barriers to OOPP success included: (1) Insufficient retail pharmacy leadership support for administrative and clinical tasks for OOPP tasks; (2) excessive opioid analgesic prescribing by physicians; (3) limited uptake of naloxone by prescribers and patients; (4) out-of-pocket costs for patients to obtain naloxone; (5) lack of time, staffing, and space to provide opioid overdose prevention counseling; (6) concern for increased overdose fatalities and injection drug use in the pharmacy premises if pharmacists dispensed sterile syringes, naloxone, and/or Buprenorphine-naloxone; and (7) stigmatizing attitudes toward persons who use opioids. Conclusion: Multi-level intervention efforts that include pharmacist-prescriber communication and training, and stigma-reducing efforts in rural and small metro area regions are needed.

For any given city, on any calendar day, there will be record high and low temperatures. Which record occurred earlier? If there is a trend towards warming then, intuitively, there should be a preponderance of record highs occurring more recently than the record lows for each of the 365 calendar days. We are interested in modeling the joint distribution of appearances of the extremes but not these values themselves. We develop a bivariate discrete distribution modeling the joint indices of maximum and minimum in a sequence of independent random variables sampled from different distributions. We assume these distributions share a proportional hazard rate and develop regression methods for these paired values. This approach has reasonable power to detect a small mean change over a decade. Using readily available public data, we examine the daily calendar extreme values of five US cities for the decade 2011"“2020. We develop linear regression models for these data, describe models to account for calendar-date dependence, and use diagnostic measures to detect remarkable observations.

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.

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.

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.

Air quality management is increasingly focused not only on across-the-board reductions in ambient pollution concentrations but also on identifying and remediating elevated exposures that often occur in traditionally disadvantaged communities. Remote sensing of ambient air pollution using data derived from satellites has the potential to better inform management decisions that address environmental disparities by providing increased spatial coverage, at high-spatial resolutions, compared to air pollution exposure estimates based on ground-based monitors alone. Daily PM2.5 estimates for 2015"“2018 were estimated at a 1 km2 resolution, derived from NASA"™s Moderate Resolution Imaging Spectroradiometer (MODIS) satellite instrument and the Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm in order to assess the utility of highly refined spatiotemporal air pollution data in 92 California cities and in the 13 communities included in the California Community Air Protection Program. The identification of pollution hot-spots within a city is typically not possible relying solely on the regulatory monitoring networks; however, day-to-day temporal variability was shown to be generally well represented by nearby ground-based monitoring data even in communities with strong spatial gradients in pollutant concentrations. An assessment of within-ZIP Code variability in pollution estimates indicates that high-resolution pollution estimates (i.e., 1 km2) are not always needed to identify spatial differences in exposure but become increasingly important for larger geographic areas (approximately 50 km2). Taken together, these findings can help inform strategies for use of remote sensing data for air quality management including the screening of locations with air pollution exposures that are not well represented by existing ground-based air pollution monitors.

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.
