The Dietary Approaches to Stop Hypertension (DASH) diet reduces serum urate (SU); however, the impact of the DASH diet has not been previously evaluated among patients with gout. We conducted a randomized, controlled, crossover pilot study to test the effects of ~$105/week ($15/day) of dietitian-directed groceries (DDG), patterned after the DASH diet, on SU, compared with self-directed grocery shopping (SDG). Participants had gout and were not taking urate lowering therapy. Each intervention period lasted 4 weeks; crossover occurred without a washout period. The primary endpoint was SU. Compliance was assessed by end-of-period fasting spot urine potassium and sodium measurements and self-reported consumption of daily servings of fruit and vegetables. We randomized 43 participants (19% women, 49% black, mean age 59 years) with 100% follow-up. Mean baseline SU was 8.1 mg/dL (SD, 0.8). During Period 1, DDG lowered SU by 0.55 mg/dL (95% CI: 0.07, 1.04) compared to SDG by 0.0 mg/dL (95% CI: −0.44, 0.44). However, after crossover (Period 2), the SU difference between groups was the opposite: SDG reduced SU by −0.48 mg/dL (95% CI: −0.98, 0.01) compared to DDG by −0.05 mg/dL (95% CI: −0.48, 0.38; P for interaction by period = 0.11). Nevertheless, DDG improved self-reported intake of fruit and vegetables (3.1 servings/day; 95% CI: 1.5, 4.8) and significantly reduced total spot urine sodium excretion by 22 percentage points (95% CI: −34.0, −8.6). Though relatively small in scale, this pilot study suggests that dietitian-directed, DASH-patterned groceries may lower SU among gout patients not on urate-lowering drugs. However, behavior intervention crossover trials without a washout period are likely vulnerable to strong carryover effects. Definitive evaluation of the DASH diet as a treatment for gout will require a controlled feeding trial, ideally with a parallel-design.

OBJECTIVES/SPECIFIC AIMS: The Rockefeller University Center for Clinical and Translational Science (RU-CCTS), Clinical Directors Network (CDN), and Carter Burden Network (CBN), a multi-site senior services organization serving East Harlem, NY, formed a community-academic research partnership to characterize the health of the CBN seniors (many who are racial/ethnic minorities, low-income, and suffering from multiple chronic conditions) and to explore the use and associations of a measure of overall health status and frailty in this population. A simple validated measure of health status could standardize and streamline community-based translational research to study the impact of CBN’s services on health outcomes. The CCTS-funded Pilot Project aims to: 1) Engage CBN seniors and stakeholders in priority-setting, joint protocol development, research conduct, analysis and dissemination; 2) Characterize the health status of the CBN seniors using validated measures; 3) Establish an electronic database infrastructure for current and future research; 4) Understand how health and senior activities information can be used to implement programs to improve senior health and well-being. METHODS/STUDY POPULATION: 1) We used Community Engaged Research Navigation (CEnR-Nav) methods to facilitate partnership development, and to engage CBN seniors and stakeholders in each step of the research; 2) Research staff conducted recruitment, informed consent, and physical assessments (e.g., pulse, blood pressure, BMI); and administered validated surveys to collect health status information. 3) Data were captured on a REDCap-based platform. The primary outcome, frailty, was measured by the validated Short Physical Performance Battery (SPPB). 4) Secondary outcomes include the association of use of services/activities with the primary outcome. Research participants consented to sharing of their health, demographic and services utilization data compiled by CBN staff and the NYC Department for the Aging (DFTA). DFTA provided comparison datasets of de-identified health and demographic data for clients attending other NYC DFTA-funded senior centers. RESULTS/ANTICIPATED RESULTS: 1) 43 residents and stakeholders engaged in partnership-building, study design and implementation. 2) 218 participants from two senior centers were enrolled. Mean age, 68 ± 11 years; 58% Hispanic; 33% African American, 23% White, 1% Asian, 18% Unknown, 17% Other; 69% reported <$20000 annual income; 40% had not completed high school; 30% scored as moderately or severely frail; 83% were overweight or obese; and 33% reported a history of diabetes. 84% had uncontrolled high blood pressure; many participants were previously aware of their hypertension diagnosis. 3) A REDcap database was developed to store historical and prospective data. 4) Across frailty categories, there was a significant difference in utilization of non-meal (p = 0.0237) and meal services (p = 0.0127) and there was an inverse proportional relationship between the number of meal and non-meal visits, and frailty. Additional associations among health status measures (e.g., SPPB, demographics, biological measures: pulse, blood pressure, BMI; psychosocial and nutritional scales) and CBN service utilization (i.e., meals vs. non-meals activities) will be presented. DISCUSSION/SIGNIFICANCE OF IMPACT: We developed a community-academic research partnership, infrastructure and capacity, built through our Community-Engaged (CEnR-Nav) model, to conduct a pilot study characterizing the health status and services utilization of low-income minority seniors. Our pilot study identified an urgent health priority, uncontrolled hypertension in 84% of CBN’s seniors. We then leveraged the team’s expertise and CBN’s meal services program to develop a research proposal for external funding to conduct a community-based multi-component intervention study. Replacement of a typical Western diet with the Dietary Approaches to Stop Hypertension (DASH) diet has been proven to reduce blood pressure in hypertensive and normotensive individuals in as little as 14 days, yet effective implementation has been lacking, and it is relatively untested in community-living seniors who receive their meals in settings such as CBN. We are also exploring mechanistic questions that relate to blood pressure control, such as the impact of the DASH diet on inflammation, which may lead to a better understanding of the underlying mechanism of action of the DASH diet. Our community partner, CBN, was awarded the DHHS-ACL nutrition innovation grant to conduct this 2-year study with CDN and RU-CCTS. The resulting study developed out of the community engaged pilot study represents a unique combination of community-centered care, within an implementation science framework (with embedded mechanistic measures under development). This is an example of the novel, full-spectrum approach to translational research that the RU-CCTS/CDN Community Engaged Research Core has been developing over the last decade. The research to characterize CBN clients’ health status is now being extended to address cardiovascular health by way of intervening on diet quality and food insecurity, a key component of the social determinants of health, in partnership with agencies outside of the healthcare delivery system. The outcomes of the DASH Diet implementation study will also serve to inform the broader aging service provider network and the healthcare community about the impact of senior center congregate meal composition and services on health outcomes.

Bovine leukemia virus (BLV) is a retroviral infection that disrupts the immune function of infected animals. It is widespread among U.S. dairy cattle. In this pilot study, the average total IgA and IgM concentrations in milk, saliva, and serum samples from BLV ELISA-positive (ELISA+) dairy cows were compared against samples from BLV ELISA-negative (ELISA−) cows using the Kruskal–Wallis test (with ties). The results from ELISA+ cows were also stratified by lymphocyte count (LC) and proviral load (PVL). In milk and saliva from ELISA+ cows, the average total IgA and IgM concentrations were decreased compared to ELISA− cows, although this was only statistically significant for saliva IgM in cows with low PVL (p = 0.0424). Numerically, the average total IgA concentrations were 33.6% lower in milk and 23.7% lower in saliva, and the average total IgM concentrations were 42.4% lower in milk and 15.5% lower in saliva. No significant differences were observed in the total serum IgA concentrations, regardless of PVL and LC. The total serum IgM from ELISA+ cows was significantly decreased (p = 0.0223), with the largest decreases occurring in the highest PVL and LC subgroups. This pilot study is a first step in investigating the impact of BLV on mucosal immunity and will require further exploration in each of the various stages of disease progression.
