Few studies have derived data-driven dietary patterns in youth in the USA. This study examined data-driven dietary patterns and their associations with BMI measures in predominantly low-income, racial/ethnic minority US youth. Data were from baseline assessments of the four Childhood Obesity Prevention and Treatment Research (COPTR) Consortium trials: NET-Works (534 2-4-year-olds), GROW (610 3-5-year-olds), GOALS (241 7-11-year-olds) and IMPACT (360 10-13-year-olds). Weight and height were measured. Children/adult proxies completed three 24-h dietary recalls. Dietary patterns were derived for each site from twenty-four food/beverage groups using k-means cluster analysis. Multivariable linear regression models examined associations of dietary patterns with BMI and percentage of the 95th BMI percentile. Healthy (produce and whole grains) and Unhealthy (fried food, savoury snacks and desserts) patterns were found in NET-Works and GROW. GROW additionally had a dairy- and sugar-sweetened beverage-based pattern. GOALS had a similar Healthy pattern and a pattern resembling a traditional Mexican diet. Associations between dietary patterns and BMI were only observed in IMPACT. In IMPACT, youth in the Sandwich (cold cuts, refined grains, cheese and miscellaneous) compared with Mixed (whole grains and desserts) cluster had significantly higher BMI (β = 0·99 (95 % CI 0·01, 1·97)) and percentage of the 95th BMI percentile (β = 4·17 (95 % CI 0·11, 8·24)). Healthy and Unhealthy patterns were the most common dietary patterns in COPTR youth, but diets may differ according to age, race/ethnicity or geographic location. Public health messages focused on healthy dietary substitutions may help youth mimic a dietary pattern associated with lower BMI.

INTRODUCTION/BACKGROUND:Emergency department (ED) patients have higher than average levels of food insecurity. We examined the association between multiple measures of food insecurity and frequent ED use in a random sample of ED patients. METHODS:We completed survey questionnaires with randomly sampled adult patients from an urban public hospital ED (n = 2,312). We assessed food insecurity using four questions from the United States Department of Agriculture Household Food Security Survey. The primary independent variable was any food insecurity, defined as an affirmative response to any of the four items. Frequent ED use was defined as self-report of ≥4 ED visits in the past year. We examined the relationship between patient food insecurity and frequent ED use using bivariate and multivariable analyses and examined possible mediation by anxiety/depression and overall health status. RESULTS:One-third (30.9%) of study participants reported frequent ED use, and half (50.8%) reported any food insecurity. Prevalence of food insecurity was higher among frequent vs. non-frequent ED users, 62.8% vs 45.4% (P <0.001). After controlling for potential confounders, food insecurity remained significantly associated with frequent ED use (adjusted odds ratio 1.48, 95% confidence interval, 1.20-1.83). This observed association was partially attenuated when anxiety/depression and overall health status were added to models. CONCLUSION/CONCLUSIONS:The high observed prevalence of food insecurity suggests that efforts to improve care of ED patients should assess and address this need. Further research is needed to assess whether addressing food insecurity may play an important role in efforts to reduce frequent ED use for some patients.

OBJECTIVE:To update the consensus recommendations for reporting of quantitative optical coherence tomography (OCT) study results, thus revising the previously published Advised Protocol for OCT Study Terminology and Elements (APOSTEL) recommendations. METHODS:To identify studies reporting quantitative OCT results, we performed a PubMed search for the terms "quantitative" and "optical coherence tomography" from 2015 to 2017. Corresponding authors of the identified publications were invited to provide feedback on the initial APOSTEL recommendations via online surveys following the principle of a modified Delphi method. The results were evaluated and discussed by a panel of experts, and changes to the initial recommendations were proposed. A final survey was recirculated among the corresponding authors to obtain a majority vote on the proposed changes. RESULTS:One hundred sixteen authors participated in the surveys, resulting in 15 suggestions, of which 12 were finally accepted and incorporated into an updated 9-point-checklist. We harmonized the nomenclature of the outer retinal layers, added the exact area of measurement to the description of volume scans; we suggested reporting device-specific features. We advised to address potential bias in manual segmentation or manual correction of segmentation errors. References to specific reporting guidelines and room light conditions were removed. The participants' consensus with the recommendations increased from 80% for the previous APOSTEL version to greater than 90%. CONCLUSIONS:The modified Delphi method resulted in an expert-led guideline (evidence class III, GRADE criteria) concerning study protocol, acquisition device, acquisition settings, scanning protocol, fundoscopic imaging, post-acquisition data selection, post-acquisition analysis, nomenclature and abbreviations, and statistical approach. It will still be essential to update these recommendations to new research and practices regularly.

Background Active surveillance (AS) is the recommended treatment option for low-risk prostate cancer (PC). Surveillance varies in MRI, frequency of follow-up, and the Prostate Imaging Reporting and Data System (PI-RADS) score that would repeat biopsy. Purpose To compare the effectiveness and cost-effectiveness of AS strategies for low-risk PC with versus without MRI. Materials and Methods This study developed a mathematical model to evaluate the cost-effectiveness of surveillance strategies in a simulation of men with a diagnosis of low-risk PC. The following strategies were compared: watchful waiting, prostate-specific antigen (PSA) and annual biopsy without MRI, and PSA testing and MRI with varied PI-RADS thresholds for biopsy. MRI strategies differed regarding scheduling and use of PI-RADS score of at least 3, or a PI-RADS score of at least 4 to indicate the need for biopsy. Life-years, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios were calculated by using microsimulation. Sensitivity analysis was used to assess the impact of varying parameter values on results. Results For the base case of 60-year-old men, all strategies incorporating prostate MRI extended QALYs and life-years compared with watchful waiting and non-MRI strategies. Annual MRI strategies yielded 16.19 QALYs, annual biopsy with no MRI yielded 16.14 QALYs, and watchful waiting yielded 15.94 QALYs. Annual MRI with PI-RADS score of at least 3 or of at least 4 as the biopsy threshold and annual MRI with biopsy even after MRI with negative findings offered similar QALYs and the same unadjusted life expectancy: 23.05 life-years. However, a PI-RADS score of at least 4 yielded 42% fewer lifetime biopsies. With a cost-effectiveness threshold of $100 000 per QALY, annual MRI with biopsy for lesions with PI-RADS scores of 4 or greater was most cost-effective (incremental cost-effectiveness ratio, $67 221 per QALY). Age, treatment type, risk of initial grade misclassification, and quality-of-life impact of procedural complications affected results. Conclusion The use of active surveillance (AS) with biopsy decisions guided by findings from annual MRI reduces the number of biopsies while preserving life expectancy and quality of life. Biopsy in lesions with PI-RADS scores of 4 or greater is likely the most cost-effective AS strategy for men with low-risk prostate cancer who are younger than 70 years. © RSNA, 2021 Online supplemental material is available for this article.

BACKGROUND:The Emergency Medicine Palliative Care Access (EMPallA) trial is a large, multicenter, parallel, two-arm randomized controlled trial in emergency department (ED) patients comparing two models of palliative care: nurse-led telephonic case management and specialty, outpatient palliative care. This report aims to: 1) report baseline demographic and quality of life (QOL) data for the EMPallA cohort, 2) identify the association between illness type and baseline QOL while controlling for other factors, and 3) explore baseline relationships between illness type, symptom burden, and loneliness. METHODS: < 50%) are eligible for enrollment. Baseline data includes self-reported demographics, QOL measured by the Functional Assessment of Cancer Therapy-General (FACT-G), loneliness measured by the Three-Item UCLA Loneliness Scale, and symptom burden measured by the Edmonton Revised Symptom Assessment Scale. Descriptive statistics were used to analyze demographic variables, a linear regression model measured the importance of illness type in predicting QOL, and chi-square tests of independence were used to quantify relationships between illness type, symptom burden, and loneliness. RESULTS:Between April 2018 and April 3, 2020, 500 patients were enrolled. On average, end-stage organ failure patients had lower QOL as measured by the FACT-G scale than cancer patients with an estimated difference of 9.6 points (95% CI: 5.9, 13.3), and patients with multiple conditions had a further reduction of 7.4 points (95% CI: 2.4, 12.5), when adjusting for age, education level, race, sex, immigrant status, presence of a caregiver, and hospital setting. Symptom burden and loneliness were greater in end-stage organ failure than in cancer. CONCLUSIONS:The EMPallA trial is enrolling a diverse sample of ED patients. Differences by illness type in QOL, symptom burden, and loneliness demonstrate how distinct disease trajectories manifest in the ED.

We assessed whether videos with medical footage of organ preservation and transplantation plus sad, unresolved, or uplifting stories differentially affect deceased organ donor registration among clients in Latinx-owned barbershops and beauty salons. In a 2 × 3 randomized controlled trial, participants (N = 1,696, mean age 33 years, 67% female) viewed one of six videos. The control portrayed a mother who received a kidney (uplifting), excluding medical footage. Experimental videos included medical footage and/or showed a mother waiting (unresolved) or sisters mourning their brother's death (sad). Regression models assessed relative impact of medical footage and storylines on: (1) registry enrollment, (2) donation willingness stage of change, and (3) emotions. Randomization yielded approximately equal groups relative to age, sex, education, religion, nativity, baseline organ donation willingness, beliefs, and emotions. Overall, 14.8% of participants registered. Neither medical footage, sad, nor unresolved stories differentially affected registration and changes in organ donation willingness. Sad and unresolved stories increased sadness and decreased positive affect by ~0.1 logits compared with the uplifting story. Educational videos about organ donation which excluded or included medical footage and varying emotional valence of stories induced emotions marginally but did not affect viewers' registration decisions differently. Heterogeneity of responses within video groups might explain the attenuated impact of including medical footage and varying emotional content. In future work, we will report qualitative reasons for participants' registration decisions by analyzing the free text responses from the randomized trial and data from semistructured interviews that were conducted with a subset of participants.

BACKGROUND:The New York State (NYS) Level of Care for Alcohol and Drug Treatment Referral (LOCADTR) was launched in 2015 to determine the most appropriate level of care for individuals seeking addiction treatment. However, research has not studied its predictive validity. We examined the predictive validity of the LOCADTR recommendation for outpatient treatment by determining whether those who entered a level of care (LOC) concordant with the LOCADTR recommendation differed in continuous engagement in treatment compared to those who entered a discordant LOC. METHODS:The study combined data from two NYS administrative sources, the LOCADTR database and a treatment registry. The study examined characteristics of the clients who entered concordant and discordant LOCs as well as tested for differences in continuous engagement of clients who entered discordant care compared to a propensity score-matched comparison group of clients who entered the concordant LOC. RESULTS:Among clients for whom the LOCADTR recommended the outpatient LOC, concordant clients who entered the outpatient LOC were more likely to be retained in care than discordant clients who entered the inpatient LOC (aOR = 0.53; 95% CI = 0.36, 0.77). We did not observe statistical differences in continuous engagement among clients who were recommended for outpatient and entered that LOC versus those who entered the outpatient rehabilitation LOC instead (aOR = 1.08; 95% CI = 0.90, 1.30). CONCLUSION/CONCLUSIONS:This study provides support for predictive validity of recommendations stemming from the LOCADTR. Clients, treatment providers, and payers benefited from a tool that provides clear guidance and predictively valid recommendations for treatment placement. The study found that clients were more likely to be retained in treatment for 6 months or longer if admitted to outpatient care, as recommended by the LOCADTR algorithm, rather than to inpatient treatment. One factor accounting for the longer engagement in outpatient care is the low level of continuity of care among patients being discharged from inpatient treatment.

OBJECTIVE:To describe the perceived qualities of successful palliative care (PC) providers in the emergency department (ED), barriers and facilitators to ED-PC, and clinicians' perspectives on the future of ED-PC. METHOD/METHODS:This qualitative study using semi-structured interviews was conducted in June-August 2020. Interviews were analyzed via a two-phase Rapid Analysis. The study's primary outcomes (innovations in ED-PC during COVID) are published elsewhere. In this secondary analysis, we examine interviewee responses to broader questions about ED-PC currently and in the future. RESULTS:PC providers perceived as successful in their work in the ED were described as autonomous, competent, flexible, fast, and fluent in ED language and culture. Barriers to ED-PC integration included the ED environment, lack of access to PC providers at all times, the ED perception of PC, and the lack of a supporting financial model. Facilitators to ED-PC integration included proactive identification of patients who would benefit from PC, ED-focused PC education and tools, PC presence in the ED, and data supporting ED-PC. Increased primary PC education for ED staff, increased automation, and innovative ED-PC models were seen as areas for future growth. SIGNIFICANCE OF RESULTS/CONCLUSIONS:Our findings provide useful information for PC programs considering expanding their ED presence, particularly as this is the first study to our knowledge that examines traits of successful PC providers in the ED environment. Our findings also suggest that, despite growth in the arena of ED-PC, barriers and facilitators remain similar to those identified previously. Future research is needed to evaluate the impact that ED-PC initiatives may have on patient and system outcomes, to identify a financial model to maintain ED-PC integration, and to examine whether perceptions of successful providers align with objective measures of the same.
