Background: Despite the abundance of data documenting the consequences of poor sleep quality on blood pressure (BP), no previous study to our knowledge has addressed the impact of sleep improvement on resistant hypertension among patients with chronic kidney disease (CKD). Methods: The aim of this pilot study was to determine whether improved sleep quality and duration will improve BP control in patients with resistant hypertension and CKD. It was a prospective single-center cohort study that involved 30 hypertensive subjects with CKD presenting with primary resistant hypertension and poor sleep quality or duration <6 h/night. Sleep quality and duration were modified using either sleep hygiene education alone or adding sleep medication. The cohort’s BP was followed every 3 months for 6-month duration. The average home and clinic BPs were collected at each follow-up visit. The primary outcome baseline change in systolic BP (SBP) and diastolic BP (DBP; home and clinic) at 3 and 6 months after documented sleep improvement. Secondary outcomes included change from baseline in mean arterial pressure, and delta SBP after sleep improvement. Results: African American patients represented 50% of the cohort. All patients had evidence of CKD with GFR ≤60 mL/min and were obese with 40% having type 2 diabetes mellitus. The primary endpoint of change in clinic SBP and DBP was significantly reduced at 3 months, baseline 156 ± 15/88 ± 8 vs. 3 months 125 ± 14/73 ± 7 (p < 0.0001). This difference persisted at 6 months. However, there was no further reduction in-home or clinic BPs between the 3- and 6-month periods. Home and clinic average delta SBP change at 3 months from baseline was –34.4 ± 15 and –30.8 ± 19 mm Hg respectively. Delta SBP change was associated with sleep improvement of >6 h/night, that is, gaining an extra 3–4 h’ sleep duration, home; R2 = 0.66, p < 0.0001 and clinic; R2 = 0.49, p < 0.0001. Conclusion: Optimizing sleep quality and duration to >6 h/night improved BP control and was associated with a significant delta change in SBP within 3 months of follow-up. Physicians should obtain a sleep history in patients with CKD who present with resistant hypertension.

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.

This paper describes an instrument developed and used with an experimental methodology in a pilot study of stacking in football and baseball. The instrument was a positional profile purporting to represent an evaluation of young athletes on a number of position-relevant traits. Respondents were asked to assign each player to a position solely on the basis of this written evaluation. The race of the profiled player was systematically varied in order to measure the impact of race on positional assignment. Preliminary results showed that coaches achieve a high degree of consensus when making assignments on the basis of the written evaluations alone, and players who have been identified as white are significantly more likely to be assigned to the quarterback position than are players identified as black. No other evidence of racial differences in positional assignment was indicated.

AbstractOutbreak of global pandemic Coronavirus disease 2019 (COVID-19) has so far caused countless morbidity and mortality. However, a detailed report on the impact of COVID-19 on hypertension (HTN) and ensuing cardiac injury is unknown. Herein, we have evaluated the association between HTN and cardiac injury in 388 COVID-19 (47.5 ± 15.2 years) including 75 HTN and 313 normotension. Demographic data, cardiac injury markers, other laboratory findings, and comorbidity details were collected and analyzed. Compared to patients without HTN, hypertensive-COVID-19 patients were older, exhibited higher C-reactive protein (CRP), erythrocyte sedimentation rate, and comorbidities such as diabetes, coronary heart disease, cerebrovascular disease and chronic kidney disease. Further, these hypertensive-COVID-19 patients presented more severe disease with longer hospitalization time, and a concomitant higher rate of bilateral pneumonia, electrolyte disorder, hypoproteinemia and acute respiratory distress syndrome. In addition, cardiac injury markers such as creatine kinase (CK), myoglobin, lactic dehydrogenase (LDH), and N-terminal pro brain natriuretic peptide were significantly increased in these patients. Correlation analysis revealed that systolic blood pressure correlated significantly with the levels of CK, and LDH. Further, HTN was associated with increased LDH and CK-MB in COVID- 19 after adjusting essential variables. We also noticed that patients with elevated either high sensitivity-CRP or CRP demonstrated a significant high level of LDH along with a moderate increase in CK (p = 0.07) and CK-MB (p = 0.09). Our investigation suggested that hypertensive patients presented higher risk of cardiac injury and severe disease phenotype in COVID-19, effectively control blood pressure in HTN patients might improve the prognosis of COVID-19 patients.

Objective. To examine the feasibility of a prototype Teaching Kitchen (TK) self-care intervention that offers the combination of culinary, nutrition, exercise, and mindfulness instruction with health coaching; and to describe research methods whereby the impact of TK models can be scientifically assessed. Design. Feasibility pilot study. Subjects were recruited, screened, and consented to participate in 14- or 16-week programs. Feasibility was assessed through ease of recruitment and attendance. One-sample t tests and generalized estimating equation models were used to compare differences in groups. Setting. Workplace. Subjects. Two cohorts of 20 employees and their partners. Results. All 40 participants completed the program with high attendance (89%) and response rates on repeated assessments. Multiple changes were observed in biomarkers and self-reported behaviors from baseline to postprogram including significant (  P < .05) decreases from baseline to postprogram in body weight (−2.8 kg), waist circumference (−2.2 in.), systolic and diastolic blood pressure (−7.7 and −6.3 mm Hg, respectively), and total cholesterol (−7.5 mg/dL). While changes in all of the aforementioned biomarkers persisted over the 12-month follow-up (n = 32), only changes in waist circumference and diastolic blood pressure remained statistically different at 12 months. Conclusions. These study findings suggest that a TK curriculum is feasible within a workplace setting and that its impact on relevant behavioral and clinical outcomes can be scientifically assessed.
