OBJECTIVES/OBJECTIVE:The number of older adults on methadone maintenance treatment (MMT) for opioid use disorder is increasing, but little is known about the characteristics and healthcare needs of this aging treatment population. This population may experience accelerated aging due to comorbidities and health behaviors. The aim of this study was to compare the prevalence of geriatric conditions among adults age ≥50 on MMT to a nationally representative sample of community-dwelling older adults. METHODS:We performed a geriatric assessment on 47 adults age ≥50 currently on MMT enrolled in 2 opioid treatment programs, in New York City and in East Providence, Rhode Island. We collected data on self-reported geriatric conditions, healthcare utilization, chronic medical conditions, physical function, and substance use. The results were compared to 470 age, sex, and race/ethnicity-matched adults in the national Health and Retirement Study. RESULTS:The mean age of the study sample was 58.8 years and 23.4% were female. The most common chronic diseases were hypertension (59.6%) and arthritis (55.3%) with 66% reporting ≥2 diseases. For geriatric conditions, adults on MMT had a significantly higher prevalence of mobility, hearing, and visual impairments as well as falls, urinary incontinence, chronic pain, and insomnia than the Health and Retirement Study sample. CONCLUSIONS:Older adults on MMT in 2 large opioid treatment programs have a high prevalence of geriatric conditions. An interdisciplinary, geriatric-based approach to care that focuses on function and addresses geriatric conditions is needed to improve the health of this growing population.

BACKGROUND/UNASSIGNED:Fibroblast growth factor 23 (FGF-23) regulates phosphorus and is associated with cardiovascular disease (CVD), particularly in patients with chronic kidney disease. However, data are limited regarding its contribution to different CVD subtypes across wide age ranges in the general population. METHODS/UNASSIGNED:Using data from ARIC, we evaluated the associations of FGF-23 with heart failure (HF), coronary heart disease (CHD), stroke, and composite CVD (any CVD event) in 12,039 participants at mid-life (visit 3 [1993-1995], mean age 60.0 [SD 5.7] years) and 5608 of the same participants at late-life (visit 5 [2011-2013], 75.5 [5.1] years). RESULTS/UNASSIGNED:-for-difference < 0.001). We observed similar patterns in key demographic and clinical subgroups without interactions. Among CVD subtypes, HF was the only subtype robustly associated with higher FGF-23 at both visits. CONCLUSION/UNASSIGNED:Higher FGF-23 concentrations at late-life but not necessarily at mid-life were independently associated with the risk of CVD. Among CVD subtypes tested, only HF showed robust associations with FGF-23 at both mid-life and late-life.

PURPOSE/OBJECTIVE:Population-based surveys are possible sources from which to draw representative control data for case-control studies. However, these surveys involve complex sampling that could lead to biased estimates of measures of association if not properly accounted for in analyses. Approaches to incorporating complex-sampled controls in density-sampled case-control designs have not been examined. METHODS:We used a simulation study to evaluate the performance of different approaches to estimating incidence density ratios (IDR) from case-control studies with controls drawn from complex survey data using risk-set sampling. In simulated population data, we applied four survey sampling approaches, with varying survey sizes, and assessed the performance of four analysis methods for incorporating survey-based controls. RESULTS:Estimates of the IDR were unbiased for methods that conducted risk-set sampling with probability of selection proportional to survey weights. Estimates of the IDR were biased when sampling weights were not incorporated, or only included in regression modeling. The unbiased analysis methods performed comparably and produced estimates with variance comparable to biased methods. Variance increased and confidence interval coverage decreased as survey size decreased. CONCLUSIONS:Unbiased estimates are obtainable in risk-set sampled case-control studies using controls drawn from complex survey data when weights are properly incorporated.

INTRODUCTION/BACKGROUND:Smoking is independently associated with erectile dysfunction and cardiovascular disease. Given existing similarities in the constituents of e-cigarettes or ENDS and cigarettes, this study examines the association between ENDS use and erectile dysfunction. METHODS:Data from Wave 4 (2016-2018) of the Population Assessment of Tobacco and Health study were analyzed in 2020. Male participants aged ≥20 years who responded to the erectile dysfunction question were included. Multivariable logistic regression models examined the association of ENDS use with erectile dysfunction within the full sample and in a restricted sample (adults aged 20-65 years with no previous cardiovascular disease diagnosis) while adjusting for multiple risk factors. RESULTS:The proportion of erectile dysfunction varied from 20.7% (full sample) to 10.2% (restricted sample). The prevalence of current ENDS use within the full and restricted samples was 4.8% and 5.6%, respectively, with 2.1% and 2.5%, respectively, reporting daily use. Current daily ENDS users were more likely to report erectile dysfunction than never users in both the full (AOR=2.24, 95% CI=1.50, 3.34) and restricted (AOR=2.41, 95% CI=1.55, 3.74) samples. In the full sample, cardiovascular disease history (versus not present) and age ≥65 years (versus age 20-24 years) were associated with erectile dysfunction (AOR=1.39, 95% CI=1.10, 1.77; AOR= 17.4, 95% CI=12.15, 24.91), whereas physical activity was associated with lower odds of erectile dysfunction in both samples (AOR range=0.44-0.58). CONCLUSIONS:The use of ENDS seems to be associated with erectile dysfunction independent of age, cardiovascular disease, and other risk factors. While ENDS remain under evaluation for harm reduction and smoking-cessation potential, ENDS users should be informed about the possible association between ENDS use and erectile dysfunction.

Introduction:Vitamin D deficiency and insufficiency are highly prevalent among several populations across the globe. Numerous studies have shown a significant correlation between body-mass-index (BMI) and Vitamin D status, however, some results differed according to ethnicity. Despite the abundance of sunshine throughout the year, vitamin D deficiency is prominent in the United Arab Emirates (UAE). In this study, we analyzed the UAE Healthy Future Study (UAEHFS) pilot data to investigate the association between serum 25-hydroxyvitamin D (25(OH)D) and % body fat (BF) composition as well as BMI. Material and methods:Data from a total of 399 Emirati men and women aged ≥ 18 years were analyzed. Serum 25(OH)D and standard measures of weight and height were included in the analyses. Vitamin D deficiency was defined as serum 25(OH)D concentration<20 ng/ml. Multivariate quantile regression models were performed to explore the relationship between serum 25(OH)D levels and % BF composition and BMI correspondingly. Results:There were 281 (70.4%) males and 118 (29.6%) females included in this study. More than half of the study participants had vitamin D insufficiency (52.4%), and nearly a third had vitamin D deficiency (30.3%); while only 17.3% had optimal levels. A statistically significant negative association between serum 25(OH) D levels and % BF composition was observed at intermediate percentiles while a statistically significant negative association between serum 25(OH)D and BMI was only observed at the median (50th percentile). Conclusion:The study findings support the association between low serum 25(OH) D levels (low vitamin D status) and high % BF composition and high BMI among adult Emiratis. Further longitudinal data from the prospective UAEHFS could better elucidate the relationship between serum 25(OH) D levels, % BF composition, and BMI in the context of various health outcomes among this population.

Background: Electronic cigarettes (EC) have been proposed as a harm-reducing alternative in smokers with COPD. Racial and ethnic differences can affect the extent to which smokers in the general population switch from combustible cigarettes (CC) to EC. To help design a targeted intervention for smokers with COPD, we conducted a mixed methods study assessing the relationship between race/ethnicity and switching from CC to EC; and evaluated whether it is mediated by social norms, risk perception, and overall opinions of CC and EC.
Method(s): We recruited patients with COPD, aged 21 to 75, listed as current smokers in the NYU Langone Health electronic health record by phone, mail, and My Chart. Smokers who had moderate COPD (based on the COPD Assessment Test score (CAT)), who smoked >=5 CC a day at least 4 days a week and were interested in quitting were eligible. We randomized participants to EC or nicotine replacement therapy (NRT) for switching from CC. Over 12 weeks, participants received 5 counseling sessions and were asked about their COPD symptoms, CC use, NRT/EC use, and nicotine withdrawal symptoms. We used Ecological Momentary Assessment (four text messages/day) to assess current EC/NRT and CC use. We analyzed the influence of race and ethnicity on switching, considering social norms, risk perception, media influence and overall opinions of tobacco and EC as possible mediators. We conducted in-depth interviews to gain descriptive explanations of study experience and reasons for switching or lack thereof. We used chi squared tests to compare categorical variables and analysis of variance for continuous ones.
Result(s): Among the 48 participants, the average age was 60 (STD 8.2) years and 54% were female. Races/ethnicities were 8% Black; 8% Hispanic/Latino; 81% White; and 3% Other/Not Reported. There was a trend towards decreased dyspnea and COPD symptoms, as well as decreased CC use, in the EC arm compared to the NRT arm. We are still collecting the qualitative data on switching perceptions.
Conclusion(s): Understanding the extent to which racial and ethnic differences in switching from CC to EC can be attributed to social norms, risk perception, media influence, and overall opinions of tobacco and EC; may allow us to design a more effective, more engaging smoking cessation intervention

INTRODUCTION:CareMOBI (Mhealth for Organizations to Bolster Interconnectedness) is a mobile application designed to facilitate information exchange between primary care providers (PCPs) and adult day centers (ADCs). A key function of CareMOBI is to synthesize information collected outside of the provider's office (ie,: in the ADC or at home) and distill the most relevant data points into an exportable clinical summary that can help inform clinical decision making by the PCP with information from outside providers who are not formally embedded within health systems. In this study, we used a qualitative approach to understand the acceptability and utility of the clinical summary template within CareMOBI. METHODS:Purposive sampling, followed by snowball sampling, was used to recruit PCPs from a variety of primary care practice settings (i.e. home-based, academic). Semi-structured interviews were conducted virtually to elicit feedback on the user-experience after interaction with a prototype template. Interviews were recorded, transcribed, and analyzed using content analysis. RESULTS:Our sample (n = 10) consisted of physicians and nurse practitioners in a variety of settings. Feedback suggested that the summary template facilitates interdisciplinary, bidirectional, succinct, and relevant information exchange across care teams. The summary template effectively integrates observations and assessments from team members, centralizes them, and allows PCPs to hone in on the most salient components to inform clinical decision making for the geriatric patient. The summary gave PCPs "live texture" about what was happening outside the office and represented a significant improvement over other methodologies of information exchange. Prior to implementation into clinical practice, several refinements are necessary based on feedback including integration into the PCP's workflow. CONCLUSIONS:The template was viewed by PCPs as a concise and actionable record, in contrast to current communication which is characterized as "bloated"-containing too many pages on nonessential information. The summary could potentially save PCP's time in locating and analyzing historical data to enable rapid patient assessment and prompt more ready and informed action.
