RESUMEN

BACKGROUND: Hypertension affects one-third of adults in the United States and is the leading risk factor for death. Underserved populations are seen disproportionately in the emergency department (ED) and tend to have worse blood pressure (BP) control. For adults, a lack of hypertension knowledge is a common barrier to hypertension control, while social support is a strong facilitator, and providing information that is culturally sensitive and relevant is especially important in this context. The youth experience increased confidence when given the responsibility to provide health education and care navigation to others. As such, we planned a randomized controlled trial (RCT) for the effectiveness of a digital youth-led hypertension education intervention for adult patients in the ED with hypertension, focusing on change in BP and hypertension knowledge. OBJECTIVE: In preparation for an RCT, we conducted a formative study to determine acceptable and easily comprehensible ways to present hypertension information to adults with hypertension and optimal ways to engage youth to support adults on how to achieve better hypertension control. METHODS: After creating an intervention prototype with 6 weekly self-guided hypertension online modules, we recruited 12 youth (adolescents, aged 15-18 years) for 3 focus groups and 10 adult ED patients with hypertension for individual online interviews to garner feedback on the prototype. After completing a brief questionnaire, participants were asked about experiences with hypertension, preferences for a hypertension education intervention, and acceptability, feasibility, obstacles, and solutions for intervention implementation with youth and adults. The moderator described and showed participants the prototyped intervention process and materials and asked for feedback. Questionnaire data were descriptively summarized, and qualitative data were analyzed using the template organizing style of analysis by 3 study team members. RESULTS: Participants showed great interest in the intervention prototype, thought their peers would find it acceptable, and appreciated its involvement of youth. Youth with family members with hypertension reported that their family members need more support for their hypertension. Youth suggested adding more nutrition education activities to the intervention, such as a sodium tracker and examples of high-sodium foods. Adults discussed the need for a hypertension support intervention for themselves and the expected benefits to youth. They mentioned the overwhelming amount of hypertension information available and appreciated the intervention's concise content presentation. They suggested adding more mental health and smoking cessation resources, information about specific hypertension medications, and adding active links for health care information. CONCLUSIONS: Based on focus groups and interviews with participants, a youth-led digital hypertension intervention is an acceptable strategy to engage both adults with hypertension and youth. Incorporating participant suggestions into the intervention may improve its clarity, engagement, and impact when used in a subsequent RCT.

RESUMEN

BACKGROUND: Among cancer survivors, diabetes is associated with greater morbidity and mortality. The objective of this study is to describe racial/ethnic disparities in diabetes care quality (DCQ) among cancer survivors compared to non-cancer controls. METHODS: We used Medical Expenditure Panel Survey Household Component data (2010-2018). Black, non-Hispanic White (NHW), and Hispanic respondents diagnosed with diabetes and cancer were frequency matched 1:5 to non-cancer controls. Multivariable logistic regression estimated associations for specific indices and overall DCQ by race/ethnicity stratified by cancer site/status in partially adjusted (not controlling for socioeconomic indicators) and fully adjusted models. RESULTS: The final sample of 4775 included cancer survivors (n = 907 all cancers; n = 401 breast; n = 167 colon; n = 339 prostate) and non-cancer controls (n = 3868) matched by age, race/ethnicity, and year. In partially adjusted models, Black (adjusted odds ratio, AOR) 0.67 [95% CI 0.54-0.83]) and Hispanic (AOR 0.68 [95% CI 0.54-0.87]) non-cancer controls had significant disparities for overall DCQ compared to NHWs. Among cancer survivors, DCQ disparities for Black (AOR 0.62, [95% CI 0.4-0.96]) and Hispanics (AOR 0.60, [95% CI 0.38-0.97]) were identified. Among prostate cancer survivors, DCQ disparities were identified for Blacks (AOR 0.38; [95% CI 0.20-0.72]) and Hispanics (AOR 0.39; [95% CI 0.17-0.89]) compared to NHWs. Racial disparities among Black controls and Black prostate cancer survivors remained significant in fully adjusted models. CONCLUSION: Diabetes care disparities are evident among cancer survivors and salient among non-cancer controls. Strategies to promote health equity should target specific care indices among survivors and emphasize equitable DCQ strategies among Black and Hispanic communities.

RESUMEN

BACKGROUND: Young adults with cancer diagnosed between the ages of 18 to 39 are recognized as a vulnerable group with unique emotional, social, and practical needs that put them at risk of poor psychosocial outcomes and impaired health-related quality of life (HRQOL). This study describes the protocol of a randomized controlled trial to evaluate the efficacy of Bright IDEAS-Young Adults (Bright IDEAS-YA), a problem-solving skills training intervention, on psychosocial outcomes of young adults newly diagnosed with cancer. METHODS: Bright IDEAS-YA is a two-arm, parallel, randomized controlled trial. Young adults are eligible if they are 18-39 years of age, within four months of a first cancer diagnosis, and receiving systemic therapy with life expectancy of at least six months. Participants are randomized 1:1 to Bright IDEAS-YA or enhanced usual care. Survey measures are completed at enrollment and 3, 6, 12, and 24 months. The primary endpoint will be the estimated change from baseline to 6 months in symptoms of depression, anxiety, and psychosocial HRQOL. The other time points are secondary endpoints. Mediators and moderators will be examined. CONCLUSIONS: This randomized trial will determine the efficacy of Bright IDEAS-YA on psychosocial outcomes for young adults newly diagnosed with cancer. Analyses will also examine mechanisms of action and potentially identify subgroups for whom the intervention is particularly useful. TRIAL REGISTRATION: clinicaltrials.gov #NCT04585269.

RESUMEN

BACKGROUND: Persons with diabetes have 27% elevated risk of developing colorectal cancer (CRC) and are disproportionately from priority health disparities populations. Federally qualified health centers (FQHCs) struggle to implement CRC screening programs for average risk patients. Strategies to effectively prioritize and optimize CRC screening for patients with diabetes in the primary care safety-net are needed. METHODS: Guided by the Exploration, Preparation, Implementation and Sustainment Framework, we conducted a stakeholder-engaged process to identify multi-level change objectives for implementing optimized CRC screening for patients with diabetes in FQHCs. To identify change objectives, an implementation planning group of stakeholders from FQHCs, safety-net screening programs, and policy implementers were assembled and met over a 7-month period. Depth interviews (n = 18-20) with key implementation actors were conducted to identify and refine the materials, methods and strategies needed to support an implementation plan across different FQHC contexts. The planning group endorsed the following multi-component implementation strategies: identifying clinic champions, development/distribution of patient educational materials, developing and implementing quality monitoring systems, and convening clinical meetings. To support clinic champions during the initial implementation phase, two learning collaboratives and bi-weekly virtual facilitation will be provided. In single group, hybrid type 2 effectiveness-implementation trial, we will implement and evaluate these strategies in a in six safety net clinics (n = 30 patients with diabetes per site). The primary clinical outcomes are: (1) clinic-level colonoscopy uptake and (2) overall CRC screening rates for patients with diabetes assessed at baseline and 12-months post-implementation. Implementation outcomes include provider and staff fidelity to the implementation plan, patient acceptability, and feasibility will be assessed at baseline and 12-months post-implementation. DISCUSSION: Study findings are poised to inform development of evidence-based implementation strategies to be tested for scalability and sustainability in a future hybrid 2 effectiveness-implementation clinical trial. The research protocol can be adapted as a model to investigate the development of targeted cancer prevention strategies in additional chronically ill priority populations. TRIAL REGISTRATION: This study was registered in ClinicalTrials.gov (NCT05785780) on March 27, 2023 (last updated October 21, 2023).

RESUMEN

Chronic disruption of circadian rhythms by night shift work is associated with an increased breast cancer risk. However, little is known about the impact of night shift on peripheral circadian genes (CGs) and circadian-controlled genes (CCGs) associated with breast cancer. Hence, we assessed central clock markers (melatonin and cortisol) in plasma, and peripheral CGs (PER1, PER2, PER3, and BMAL1) and CCGs (ESR1 and ESR2) in peripheral blood mononuclear cells (PBMCs). In day shift nurses (n = 12), 24-h rhythms of cortisol and melatonin were aligned with day shift-oriented light/dark schedules. The mRNA expression of PER2, PER3, BMAL1, and ESR2 showed 24-h rhythms with peak values in the morning. In contrast, night shift nurses (n = 10) lost 24-h rhythmicity of cortisol with a suppressed morning surge but retained normal rhythmic patterns of melatonin, leading to misalignment between cortisol and melatonin. Moreover, night shift nurses showed disruption of rhythmic expressions of PER2, PER3, BMAL1, and ESR2 genes, resulting in an impaired inverse correlation between PER2 and BMAL1 compared to day shift nurses. The observed trends of disrupted circadian markers were recapitulated in additional day (n = 20) and night (n = 19) shift nurses by measurement at early night and midnight time points. Taken together, this study demonstrated the misalignment of cortisol and melatonin, associated disruption of PER2 and ESR2 circadian expressions, and internal misalignment in peripheral circadian network in night shift nurses. Morning plasma cortisol and PER2, BMAL1, and ESR2 expressions in PBMCs may therefore be useful biomarkers of circadian disruption in shift workers.

RESUMEN

Portable air cleaners (PACs) equipped with HEPA filters are gaining attention as cost-effective means of decreasing indoor particulate matter (PM) air pollutants and airborne viruses. However, the performance of PACs in naturalistic settings and spaces beyond the room containing the PAC is not well characterized. We conducted a single-blinded randomized cross-over interventional study between November 2020 and May 2021 in the homes of adults who tested positive for COVID-19. The intervention was air filtration with PAC operated with the HEPA filter set installed ("filter" condition) versus removed ("sham" condition, i.e., control). Sampling was performed in 29 homes for two consecutive 24-hour periods in the primary room (containing the PAC) and a secondary room. PAC effectiveness, calculated as reductions in overall mean PM2.5 and PM10 concentrations during the filter condition, were for the primary rooms 78.8% and 63.9% (n = 23), respectively, and for the secondary rooms 57.9% and 60.4% (n = 22), respectively. When a central air handler (CAH) was reported to be in use, filter-associated reductions of PM were statistically significant during the day (06:00-22:00) and night (22:01-05:59) in the primary rooms but only during the day in the secondary rooms. Our study adds to the literature evaluating the real-world effects of PACs on a secondary room and considering the impact of central air systems on PAC performance.

RESUMEN

Executive function (EF) is a critical skill for academic achievement. Research on the psychosocial and environmental predictors of EF, particularly among Southeast Asian, agricultural, and low income/rural populations, is limited. Our longitudinal study explored the influence of agricultural environmental, psychosocial, and temperamental factors on children's emerging EF. Three-hundred and nine farm worker women were recruited during the first trimester of pregnancy. We evaluated the effects of prenatal insecticide exposure and psychosocial factors on "cool" (i.e., cognitive: A-not-B task, looking version) and "hot" EF (i.e., affective, response inhibition) measures of emerging EF. Maternal urine samples were collected monthly during pregnancy, composited, and analyzed for dialkylphosphate (DAP) metabolites of organophosphate insecticides. Psychosocial factors included socioeconomic status, maternal psychological factors, and quality of mother-child behavioral interactions. Backward stepwise regressions evaluated predictors of children's EF at 12 (N = 288), 18 (N = 277) and 24 (N = 280) months of age. We observed different predictive models for cool EF, as measured by A-not-B task, vs. hot EF, as measured by response inhibition tasks. Report of housing quality as a surrogate for income was a significant predictor of emerging EF. However, these variables had opposite effects for cool vs. hot EF. More financial resources predicted better cool EF performance but poorer hot EF performance. Qualitative findings indicate that homes with fewer resources were in tribal areas where children must remain close to an adult for safety reasons. This finding suggests that challenging physical environments (e.g., an elevated bamboo home with no electricity or running water), may contribute to development of higher levels of response inhibition through parental socialization methods that emphasize compliance. Children who tended to show more arousal and excitability, and joy reactivity as young infants in the laboratory setting had better cognitive performance. In contrast, maternal emotional availability was a significant predictor of hot EF. As expected, increased maternal exposure to pesticides during pregnancy was associated with worse cognitive performance but was not associated with inhibitory control. Identifying risk factors contributing to the differential developmental pathways of cool and hot EF will inform prevention strategies to promote healthy development in this and other unstudied rural, low income Southeast Asian farming communities.

RESUMEN

OBJECTIVE: The COVID-19 pandemic disproportionately harmed Latino families; however, its effects on their stress and media routines remain understudied. We examined economic and parenting stress patterns during the COVID-19 pandemic and estimated associations between these forms of stress and nonadherence to American Academy of Pediatrics (AAP) infant media exposure recommendations among Latino families. We also explored how nonadherence with AAP recommendations varied with COVID-19 cases. METHODS: We analyzed baseline data from an ongoing clinical trial recruiting low-income Latino parent-infant dyads. Nonadherence with AAP media exposure recommendations (ScreenQ) and economic and parent stress were measured using parent reports. Additional variables included epidemiological data on COVID-19 cases. Linear models examined associations between the pandemic and both stress variables as well as between stress and ScreenQ. Using locally weighted scatterplot smoothing curve fitting, the rise and fall of NJ COVID-19 cases were overlayed with ScreenQ scores over time to visualize and explore trends. RESULTS: All parents identified as Latino (62.6% unemployed, 91.5% limited English proficiency). Mean infant age was 8.2 months. Parent stress increased over time during the COVID-19 pandemic (r = 0.13, p = 0.0369). After covariate adjustment, economic and parent stress were associated with increased nonadherence with AAP recommendations (standardized beta = 0.16, 95% confidence interval [CI], 0.03-0.29; standardized beta = 0.18, 95% CI, 0.04-0.31, respectively). Nonadherence to media exposure recommendations seemed to track with rises in the number of COVID-19 cases with a lag of 7 days. CONCLUSION: Parent and economic stress were associated with nonadherence to infant media exposure recommendations among Latino families. These findings highlight the need for practitioners to support families from under-resourced communities and to promote healthy media routines.

RESUMEN

BACKGROUND: Reach Out and Read (ROR) is a multi-component pediatric literacy promotion intervention. However, few studies link ROR components to outcomes. We examine associations between receipt of (1) multiple ROR components and (2) clinician modeling, a potential best practice, with enhanced home literacy environments (EHLEs) among Latino families. METHODS: We conducted secondary analyses of cross-sectional enrollment data from a randomized clinical trial at three urban community health centers between November 2020 and June 2023. Latino parents with infants 6-<9 months old were surveyed about ROR component receipt (children's book, anticipatory guidance, modeling) and EHLE (StimQ2- Infant Read Scale). We used mixed models with clinician as a random effect, adjusting for covariates. RESULTS: 440 Latino parent-infant dyads were included. With no components as the reference category, receipt of 1 component was not associated with EHLE. Receipt of 2 components (standardized beta = 0.27; 95%CI: 0.12-0.42) and 3 components (standardized beta = 0.33; 95% CI: 0.19-0.47) were associated with EHLE. In separate analyses, modeling was associated with EHLE (standardized beta = 0.16; 95%CI: 0.06-0.26). CONCLUSION: Findings support modeling as a core ROR component. Programs seeking to enhance equity by promoting EHLE should utilize such strategies as anticipatory guidance and clinician modeling in addition to book distribution. IMPACT: Reach Out and Read, a multi-component literacy promotion intervention, leverages primary care to promote equity in children's early language experiences. However, few studies link Reach Out and Read components to outcomes. Among Latino parent-infant dyads, we found that implementation of two and three components, compared to none, was associated with enhanced home literacy environments, following a dose response pattern. Parent report of clinician modeling was associated with enhanced home literacy environments. Literacy promotion programs seeking to enhance equity by promoting enhanced home literacy environments should utilize strategies in addition to book distribution, including anticipatory guidance and modeling, to maximize impact.

RESUMEN

BACKGROUND: Advances in detection and treatment for breast cancer have led to an increase in the number of individuals managing significant late and long-term treatment effects. Primary care has a role in caring for patients with a history of cancer, yet there is little guidance on how to effectively implement survivorship care evidence into primary care delivery. METHODS: This protocol describes a multi-phase, mixed methods, stakeholder-driven research process that prioritizes actionable, evidence-based primary care improvements to enhance breast cancer survivorship care by integrating implementation and primary care transformation frameworks: the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework and the Practice Change Model (PCM). Informed by depth interviews and a four round Delphi panel with diverse stakeholders from primary care and oncology, we will implement and evaluate an iterative clinical intervention in a hybrid type 1 effectiveness-implementation cluster randomized design in twenty-six primary care practices. Multi-component implementation strategies will include facilitation, audit and feedback, and learning collaboratives. Ongoing data collection and analysis will be performed to optimize adoption of the intervention. The primary clinical outcome to test effectiveness is comprehensive breast cancer follow-up care. Implementation will be assessed using mixed methods to explore how organizational and contextual variables affect adoption, implementation, and early sustainability for provision of follow-up care, symptom, and risk management activities at six- and 12-months post implementation. DISCUSSION: Study findings are poised to inform development of scalable, high impact intervention processes to enhance long-term follow-up care for patients with a history of breast cancer in primary care. If successful, next steps would include working with a national primary care practice-based research network to implement a national dissemination study. Actionable activities and processes identified could also be applied to development of organizational and care delivery interventions for follow-up care for other cancer sites. TRIAL REGISTRATION: Registered with ClinicalTrials.gov on June 2, 2022: NCT05400941.

RESUMEN

INTRODUCTION: While previous research has examined misperceptions related to Natural American Spirit (NAS), a premium cigarette brand using 'natural'-themed marketing, the longitudinal relationship between NAS-related harm beliefs and switching to NAS has not been established. METHODS: Using data from the PATH study, we modelled the longitudinal relationship between (1) brand switching and subsequent belief that one's own brand might be less harmful than other brands (Waves 1-5); (2) belief that organic and/or additive-free tobacco products are less harmful and subsequent brand switching (Waves 3-5); and (3) belief that some types of cigarettes are less harmful and subsequent brand switching (Waves 3-5) for NAS and two leading comparator brands (Camel and Marlboro). RESULTS: Among people who did not think their prior brand might be less harmful, switching to NAS or maintaining NAS preference increased the odds of believing one's own brand might be less harmful (aOR 19.4; 95% CI: 15.19, 24.8; aOR 6.1; 95% CI: 4.23, 8.67, respectively). Prior belief that organic and additive-free tobacco products were less harmful increased the odds of switching to (aOR 2.5; 95% CI: 1.68, 3.74) and decreased the odds of switching away (0.57; 955 CI: 0.36, 0.92) from NAS in the subsequent wave. Parallel analyses for Marlboro/Camel were largely null or in the opposite direction. CONCLUSIONS: NAS use may maintain or shape new beliefs that the brand may be less harmful than other brands; holding pre-existing beliefs about the relative harm of some tobacco products may increase risk for NAS use.

RESUMEN

Cadmium exposure has been associated with adverse perinatal outcomes. One possible mechanism is endocrine disruption. Studies of non-pregnant adults suggest that cadmium impacts androgen production; here, we examined these associations during pregnancy. Participants in the Understanding Pregnancy Signals and Infant Development (UPSIDE) cohort provided biospecimens and questionnaire data in each trimester (n = 272). We quantified urinary cadmium, serum total testosterone (TT), estrone, estradiol, and estriol and serum free testosterone (fT). In adjusted longitudinal models, we examined sex steroid concentrations across pregnancy in relation to specific gravity-adjusted, ln-transformed cadmium concentrations. Additionally, we examined trimester-specific associations and stratified models by fetal sex. Results are presented as percent change (%∆) in hormone concentrations. In longitudinal models, higher cadmium concentrations were associated with lower fT across pregnancy (%∆ = -5.19, 95%CI: -8.33, -1.93), with no differences in other hormones observed. In trimester-specific models, higher cadmium concentrations were associated with lower TT in trimester 2 (%∆ = -15.26, 95%CI: -25.15, -4.06) and lower fT in trimester 3 (%∆ = -14.35, 95%CI: -19.75, -8.59). Associations with TT were stronger in pregnancies carrying female fetuses. Maternal cadmium exposure may be associated with reduced testosterone in pregnancy. Additional work is necessary to understand how alterations in gestational testosterone activity may impact pregnancy and child health.

RESUMEN

BACKGROUND AND AIM: Placental efflux transporter proteins, such as BCRP, reduce the placental and fetal toxicity of environmental contaminants but have received little attention in perinatal environmental epidemiology. Here, we evaluate the potential protective role of BCRP following prenatal exposure to cadmium, a metal that preferentially accumulates in the placenta and adversely impacts fetal growth. We hypothesized that individuals with a reduced function polymorphism in ABCG2, the gene encoding BCRP, would be most vulnerable to the adverse impacts of prenatal cadmium exposure, notably, smaller placental and fetal size. METHODS: We measured cadmium in maternal urine samples at each trimester and in term placentas from UPSIDE-ECHO study participants (NY, USA; n = 269). We fit adjusted multivariable linear regression and generalized estimating equation models to examine log-transformed urinary and placental cadmium concentrations in relation to birthweight, birth length, placental weight, and fetoplacental weight ratio (FPR) and stratified models by ABCG2 Q141K (C421A) genotype. RESULTS: Overall 17% of participants expressed the reduced-function ABCG2 C421A variant (AA or AC). Placental cadmium concentrations were inversely associated with placental weight (ß = -19.55; 95%CI: -37.06, -2.04) and trended towards higher FPR (ß = 0.25; 95%CI: -0.01, 0.52) with stronger associations in 421A variant infants. Notably, higher placental cadmium concentrations in 421A variant infants were associated with reduced placental weight (ß = -49.42; 95%CI: 98.87, 0.03), and higher FPR (ß = 0.85, 95%CI: 0.18, 1.52), while higher urinary cadmium concentration was associated with longer birth length (ß = 0.98; 95%CI: 0.37, 1.59), lower ponderal index (ß = -0.09; 95%CI: 0.15, -0.03), and higher FPR (ß = 0.42; 95%CI: 0.14, 0.71). CONCLUSIONS: Infants with reduced function ABCG2 polymorphisms may be particularly vulnerable to the developmental toxicity of cadmium as well as other xenobiotics that are BCRP substrates. Additional work examining the influence of placental transporters in environmental epidemiology cohorts is warranted.

RESUMEN

INTRODUCTION: People believe that cigarettes using 'organic,' 'additive-free' or similar descriptors are less harmful than other cigarettes. Natural American Spirit (NAS) is the most popular US cigarette brand using these descriptors. This cohort study describes changes in US smokers' odds of preferring NAS and changes in NAS smokers' odds of believing their brand might be less harmful than other brands. METHODS: Data come from four waves (2013-2018) of the Population Assessment of Tobacco and Health (PATH) Study. Generalised estimating equations produced population-averaged estimates of relationships between (1) NAS brand preference and wave and (2) belief that one's own brand might be less harmful than other brands, wave and NAS brand preference. Models tested interactions by age group and sexual minority status. RESULTS: The odds that smokers preferred NAS increased by 60% in W4 relative to W1. Disproportionate preference by younger adult and sexual minority smokers was observed. The odds that NAS smokers believed their own brand might be less harmful decreased by 50% between W1 and W4, but this perception was still 16 times higher for NAS compared with non-NAS smokers. Given the increasing preference for NAS, there was no significant change in the absolute number of NAS smokers who believed their own brand might be less harmful (W1: 562 122 (95% CI 435 190 to 689 055) vs W4: 580 378 (95% CI 441 069 to 719 689)). CONCLUSIONS: Both brand popularity and concentration of brand-related harm perceptions are important for understanding population impact of changes in cigarette marketing.

RESUMEN

Adolescents and young adults (AYAs) recently diagnosed with cancer are medically vulnerable but little is known about vaccine uptake/intent in this group. AYAs reported on their COVID-19 vaccine uptake/intent. Logistic regression models examined factors associated with vaccine uptake. Higher education (adjusted odds ratio [aOR] = 1.9, 95% confidence interval [CI]: 1.0-3.5) and knowing someone diagnosed with COVID-19 (aOR = 7.2, 95% CI: 1.6-33.5) were associated with increased vaccine uptake. Prior personal diagnosis of COVID-19 (aOR = 0.1, 95% CI: 0.1-0.7) was associated with lower odds of uptake. Targeted interventions may be needed to improve uptake among this group.

INTRODUCTION: Monoclonal antibody (MAB) infusion is the first treatment to manage coronavirus 2019 (COVID-19) in an outpatient setting. Yet increased risk of severe COVID-19 illness may occur from inequities in social determinants of health including access to quality healthcare. Given the safety-net nature of emergency departments (ED), a model that puts them at the center of MAB infusion may better reach underserved patients than models that require physician referral and distribute MAB at outpatient infusion centers. We examined characteristics of two groups of patients who received MAB infusion in the Robert Wood Johnson University Hospital (RWJUH) ED in New Brunswick, New Jersey: 1) patients who tested positive for COVID-19 in the ED and received ED infusion; and 2) patients who tested positive elsewhere and were referred to the ED for infusion. The process for the latter group was similar to the more common national model of patients testing COVID-19 positive in the community and then being referred to an infusion center for MAB therapy. METHODS: We performed a cross-sectional retrospective health record review of all adult patients presenting to the ED from November 20, 2020-March 15, 2021 who received MAB infusion at RWJUH ED (N = 486). Patients were identified through the electronic health record system by an administrative query, with manual chart review for any additional characteristics not available through the query. We compared the two groups using chi-squared tests for categorical variables and t-tests for continuous variables. RESULTS: We found higher proportions of Black (18% vs 6% P < 0.001, statistically significant), Hispanic (19% vs 11% P = 0.02), Medicaid (12% vs 9% P = 0.01), and uninsured (17% vs 8% P = 0.01) patients who tested positive for COVID-19 in their ED visit and then received MAB therapy during their visit than patients tested elsewhere in the community and referred to the ED for MAB therapy. CONCLUSION: These findings suggest that providing MAB infusion in the ED allows increased access for patients traditionally marginalized from the healthcare system, who may be at risk of longer disease duration and complications from COVID-19.

RESUMEN

Individuals with COVID-19 who do not require hospitalization are instructed to self-isolate in their residences. Due to high secondary infection rates in household members, there is a need to understand airborne transmission of SARS-CoV-2 within residences. We report the first naturalistic intervention study suggesting a reduction of such transmission risk using portable air cleaners (PACs) with HEPA filters. Seventeen individuals with newly diagnosed COVID-19 infection completed this single-blind, crossover, randomized study. Total and size-fractionated aerosol samples were collected simultaneously in the self-isolation room with the PAC (primary) and another room (secondary) for two consecutive 24-h periods, one period with HEPA filtration and the other with the filter removed (sham). Seven out of sixteen (44%) air samples in primary rooms were positive for SARS-CoV-2 RNA during the sham period. With the PAC operated at its lowest setting (clean air delivery rate [CADR] = 263 cfm) to minimize noise, positive aerosol samples decreased to four out of sixteen residences (25%; p = 0.229). A slight decrease in positive aerosol samples was also observed in the secondary room. As the world confronts both new variants and limited vaccination rates, our study supports this practical intervention to reduce the presence of viral aerosols in a real-world setting.

RESUMEN

Introduction: Organophosphate (OP) insecticides are among the most abundantly used insecticides worldwide. Thailand ranked third among 15 Asian countries in its use of pesticides per unit hectare and fourth in annual pesticide use. More than 40% of Thai women of childbearing age work on farms where pesticides are applied. Thus, the potential for pregnant women and their fetuses to be exposed to pesticides is significant. This study investigated the relationship between early, mid, and late pregnancy maternal urine concentrations of OP metabolites and infant neural integrity at 5 weeks of age. Method: We enrolled women employed on farms from two antenatal clinics in the Chiang Mai province of northern Thailand. We collected urine samples monthly during pregnancy, composited them by early, mid and late pregnancy and analyzed the composited samples for dialkylphosphate (DAP) metabolites of OP insecticides. At 5 weeks after birth, nurses certified in use of the NICU Network Neurobehavioral Scale (NNNS) completed the evaluation of 320 healthy infants. We employed generalized linear regression, logistic and Poisson models to determine the association between NNNS outcomes and DAP concentrations. All analyses were adjusted for confounders and included creatinine as an independent variable. Results: We did not observe trimester specific associations between DAP concentrations and NNNS outcomes. Instead, we observed statistically significant inverse associations between NNNS arousal (ß = -0.10; CI: -0.17, -0.002; p = 0.0091) and excitability [0.79 (0.68, 0.92; p = 0.0026)] among participants with higher average prenatal DAP concentrations across pregnancy. We identified 3 NNNS profiles by latent profile analysis. Higher prenatal maternal DAP concentrations were associated with higher odds of being classified in a profile indicative of greater self-regulation and attention, but arousal and excitability scores below the 50th percentile relative to US normative samples [OR = 1.47 (CI: 1.05, 2.06; p = 0.03)]. Similar findings are also observed among infants with prenatal exposure to substances of abuse (e.g., methamphetamine). Discussion: Overall, the associations between prenatal DAP concentrations and NNNS summary scores were not significant. Further evaluations are warranted to determine the implications of low arousal and excitability for neurodevelopmental outcomes of attention and memory and whether these results are transitory or imply inadequate responsivity to stimulation among children as they develop.
