Abstract
Comorbid Type 2 diabetes (T2D), a metabolic complication of obesity, associates with worse cancer outcomes for prostate, breast, head and neck, colorectal and several other solid tumors. However, the molecular mechanisms remain poorly understood. Emerging evidence shows that exosomes carry miRNAs in blood that encode the metabolic status of originating tissues and deliver their cargo to target tissues to modulate expression of critical genes. Exosomal communication potentially connects abnormal metabolism to cancer progression. Here, we hypothesized that T2D plasma exosomes induce epithelial-mesenchymal transition (EMT) and immune checkpoints in prostate cancer cells. We demonstrate that plasma exosomes from subjects with T2D induce EMT features in prostate cancer cells and upregulate the checkpoint genes CD274 and CD155. We demonstrate that specific exosomal miRNAs that are differentially abundant in plasma of T2D adults compared to nondiabetic controls (miR374a-5p, miR-93-5p and let-7b-3p) are delivered to cancer cells, thereby regulating critical target genes. We build on our previous reports showing BRD4 controls migration and dissemination of castration-resistant prostate cancer, and transcription of key EMT genes, to show that T2D exosomes require BRD4 to drive EMT and immune ligand expression. We validate our findings with gene set enrichment analysis of human prostate tumor tissue in TGCA genomic data. These results suggest novel, non-invasive approaches to evaluate and potentially block progression of prostate and other cancers in patients with comorbid T2D.

Kibe LW, Bazargan M. Fruit and Vegetable Intake Among Older African American and Hispanic Adults With Cardiovascular Risk Factors. Gerontol Geriatr Med 2022; 8:23337214211057730. [PMID: 35340364 PMCID: PMC8943447 DOI: 10.1177/23337214211057730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/08/2021] [Accepted: 10/14/2021] [Indexed: 11/18/2022] Open
Abstract
African Americans and Hispanics are disproportionately burdened by cardiovascular risk
factors including hypertension, diabetes mellitus, and obesity. There is evidence that
fruits and vegetables have protective benefits for cardiovascular health. Factors
associated with fruit and vegetable intake among older minority adults are not well
established. A cross-sectional analysis of African American and Hispanic adults
>55 years with diagnosis of hypertension and/or diabetes was conducted. Daily intake of
fruits and vegetables was analyzed by socio-demographic, health status, health behaviors,
and access to fruits and vegetables. 77% of participants did not meet the United States
Department of Agriculture ≥5 a day serving guidelines. Fruit and vegetable consumption was
not associated with having hypertension or diabetes. Body mass index >25 and regular
exercise were significantly associated with more vegetable intake, but not fruit. African
Americans consumed significantly less fruits and vegetables than Hispanics. Among those
with access to fruits and vegetables, 78% did not meet the guidelines. Many older African
American and Hispanic adults with cardiovascular disease risk factors do not meet the
fruit and vegetable intake guidelines. Inadequate intake is worse among African Americans,
sedentary, and non-overweight/obese adults. Studies are needed to understand the barriers
associated with fruit and vegetable intake in this population.

Abstract
BACKGROUND Adequate self-care is crucial for blood pressure control. A number of hypertension (HBP) self-care instruments are available, but existing tools do not capture all the critical domains of HBP self-care and have limited evidence of reliability and validity. OBJECTIVE The purpose of this study was to develop and validate a new tool--the HBP Self-Care Profile (HBP SCP)--in a sample of inner-city residents. METHODS The HBP SCP encompasses comprehensive domains of HBP self-care behaviors. Guided by 2 validated theoretical approaches--Orem's self-care model and Motivational Interviewing--the HBP SCP includes 3 scales that can be used together or independently: Behavior, Motivation, and Self-efficacy. The sample included 213 English-speaking inner-city residents with HBP (mean age, 68.6 years; 76.1% women; 81.7% African American). RESULTS Item-total correlations ranged from 0.20 to 0.63 for Behavior, 0.46 to 0.70 for Motivation, and 0.40 to 0.74 for Self-efficacy, meeting the cutoff set a priori at 0.15. Internal consistency reliability coefficients ranged from 0.83 to 0.93. Concurrent and construct validities of the HBP SCP were achieved by significant correlations between HBP SCP scales and theoretically selected instruments (P < .05 for all correlation coefficients). The HBP SCP-Behavior scale also successfully discriminated between those with or without blood pressure control (P < .05). CONCLUSIONS The reliability and validity of the HBP SCP were supported in this sample of inner-city residents with HBP. The high reliability estimates and strong evidence of validity should allow researchers to use the HBP SCP to assess and identify gaps in HBP self-care behavior, motivation, and self-efficacy. Future research is warranted to evaluate the HBP SCP in diverse ethnic and age samples of hypertensive patient populations.

Abstract
BACKGROUND High blood pressure (HBP) self-care is critical for the control of HBP. Adequate measurement of HBP self-care is a necessary first step toward ameliorating the global pandemic of HBP. OBJECTIVE The aims of this study were to identify, describe, and critique existing HBP self-care instruments. The degree of adequacy of these instruments was evaluated against well-established behavioral guidelines for HBP care. METHODS This review was limited to articles published in English before October 2012. In addition, the following criteria were used: (1) the study described the validity and/or the reliability of a self-care/self-management instrument and (2) the study targeted patients with hypertension. Electronic database searches identified 1701 potentially relevant articles. Two authors reviewed the titles and the abstracts of all the retrieved articles independently. On the basis of the inclusion and the exclusion criteria, as well as cross-referencing, 29 articles were included in this review. RESULTS From the 29 articles, 19 unique HBP self-care instruments were identified (some were modified or translated versions of an original measure). Medication taking, a key domain of HBP self-care, was the main focus of 12 of the 19 instruments. Other key domains of HBP self-care were often missing or omitted. Seven instruments measured multiple dimensions of self-care; however, these either failed to capture all the main HBP self-care domains or had poor psychometric profiles. Nineteen of the 29 articles reported both validity and reliability, with varying degrees of rigor. CONCLUSIONS The current assessment tools do not capture all the critical elements of HBP self-care. The few instruments that attempted to measure the multiple behavioral dimensions of HBP self-care failed to report adequate levels of psychometric properties of those domains because of their incompleteness. Challenges remain in translating the HBP self-care guidelines into effective intervention and relevant assessment tools. Developing a valid and reliable instrument that captures the multidimensional nature of HBP self-care is urgently needed.

Abstract
BACKGROUND Lifestyle and socioeconomic status have been implicated in the prevalence of hypertension; thus, we evaluated factors associated with hypertension in a cohort of blacks and whites with similar socioeconomic status characteristics. METHODS AND RESULTS We evaluated the prevalence and factors associated with self-reported hypertension (SR-HTN) and ascertained hypertension (A-HTN) among 69,211 participants in the Southern Community Cohort Study. Multivariable logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for factors associated with hypertension. The prevalence of SR-HTN was 57% overall. Body mass index was associated with SR-HTN in all race-sex groups, with the OR rising to 4.03 (95% CI, 3.74-4.33) for morbidly obese participants (body mass index, >40 kg/m(2)). Blacks were more likely to have SR-HTN than whites (OR, 1.84; 95% CI, 1.75-1.93), and the association with black race was more pronounced among women (OR, 2.08; 95% CI, 1.95-2.21) than men (OR, 1.47; 95% CI, 1.36-1.60). Similar findings were noted in the analysis of A-HTN. Among those with SR-HTN and A-HTN who reported use of an antihypertensive agent, 94% were on at least one of the major classes of antihypertensive agents, but only 44% were on ≥2 classes and only 29% were on a diuretic. The odds of both uncontrolled hypertension (SR-HTN and A-HTN) and unreported hypertension (no SR-HTN and A-HTN) were twice as high among blacks as whites (OR, 2.13; 95% CI, 1.68-2.69; and OR, 1.99; 95% CI, 1.59-2.48, respectively). CONCLUSIONS Despite socioeconomic status similarities, we observed suboptimal use of antihypertensives in this cohort and racial differences in the prevalence of uncontrolled and unreported hypertension, which merit further investigation.

Abstract
OBJECTIVE Micronutrient deficiencies are hypothesized to play a role in spontaneous preterm birth (PTB; <37 weeks of gestation) and possibly the racial disparity in rates of PTB between black and white women. Yet relatively few studies have addressed the role of micronutrient deficiencies in spontaneous PTB among black and white women in the United States. The purpose of this study was to investigate whether 25-hydroxy vitamin D (25-OH-D), folate, and omega-6/omega-3 fatty acid status are associated with spontaneous PTB among black and white women in the United States. METHODS Biospecimens and medical record data for this study were derived from a subsample of the 1547 women enrolled into the Nashville Birth Cohort during 2003-2006. We randomly selected 80 nulliparous and primiparous women for whom stored plasma samples from the delivery admission were available and analyzed the stored plasma for 25-OH-D, folate, and total omega-6/omega-3 fatty acids. We used multivariate logistic regression to assess the odds of spontaneous PTB among women with 25-OH-D <20 ng/mL, folate <5 ug/L, and omega-6/omega-3 >15. RESULTS An omega-6/omega-3 ratio >15 was significantly associated with spontaneous PTB for white (adjusted odds ratio [aOR] 4.25, 95% confidence interval [CI] 1.25-14.49) but not black women (aOR 1.90, 95% CI: 0.69-5.40), whereas no significant relationships were observed for folate and 25-OH-D status and PTB for black or white women. CONCLUSION Maternal plasma total omega-6/omega-3 fatty acid ratio >15 at delivery was significantly associated with spontaneous PTB for white, but not black, women.

Abstract
OBJECTIVE To give an overview of the literature for evidence of nutrient deficiencies as contributors to the disparity in preterm birth (PTB) between African-American and Caucasian women. DESIGN Structured literature survey. METHODS We searched MEDLINE to identify observational and experimental studies that evaluated the relation between nutrient intake and/or supplementation and PTB. For nutrients for which studies supported an association, we searched MEDLINE for studies of the prevalence of deficiency in the USA by race. MAIN OUTCOME MEASURES Summarized findings on nutrients for which there is both evidence of a role in PTB and variability in the prevalence of deficiency by race. RESULTS Nutrient deficiencies for which there are varying levels of evidence for an association with PTB and a greater burden among African-American compared with Caucasian women include deficiencies of iron, folic acid, zinc, vitamin D, calcium and magnesium, and imbalance of ω-3 and ω-6 polyunsaturated fatty acids. There are inadequate high-quality studies that investigate the role of nutrient deficiencies in PTB, their potential interaction with other risks, the proportion of excess risk for which they account, and whether supplementation can reduce the risk of, and racial disparities in, PTB in US populations. CONCLUSION Deficiencies of several nutrients have varying levels of evidence of association with PTB and are of greater burden among African-American compared with Caucasian women. Although further research is needed, strategies that improve the nutritional status of African-American women may be a means of addressing a portion of the racial disparity in PTB.

Abstract
In the Institute of Medicine (IOM) macronutrient report the Committee recommended a maximal intake of < or = 25% of energy from added sugars. The primary objectives of this study were to utilize National Health and Nutrition Examination Survey (NHANES) to update the reference table data on intake of added sugars from the IOM report and compute food sources of added sugars. We combined data from NHANES with the United States Department of Agriculture (USDA) MyPyramid Equivalents Database (MPED) and calculated individual added sugars intake as percent of total energy then classified individuals into 8 added sugars percent energy categories, calculated usual intake with the National Cancer Institute (NCI) method, and compared intakes to the Dietary Reference Intakes (DRIs). Nutrients at most risk for inadequacy based on the Estimated Average Requirements (EARs) were vitamins E, A, C, and magnesium. Nutrient intake was less with each 5% increase in added sugars intake above 5-10%. Thirteen percent of the population had added sugars intake > 25%. The mean g-eq added sugars intake of 83.1 g-eq/day and added sugars food sources were comparable to the mid-1990s. Higher added sugars intakes were associated with higher proportions of individuals with nutrient intakes below the EAR, but the overall high calorie and the low quality of the U.S. diet remained the predominant issue. With over 80% of the population at risk for select nutrient inadequacy, guidance may need to focus on targeted healthful diet communication to reach the highest risk demographic groups for specific life stage nutrient inadequacies.

Abstract
This study explores African American adults' understanding of metabolic syndrome (MetS) and their motivations for making lifestyle changes. African Americans have a greater risk for components of MetS, such as hypertension. Three focus groups were conducted with African American adults (n = 11) with MetS. Content analysis revealed five themes: Threat of Poor Health, Building Trust With Providers, Gaining Social Support, Seeking Culturally Acceptable Alternatives, and Getting on Track and Staying on Track. Lifestyle interventions for African Americans with MetS need to focus on building trust, developing self-monitoring skills, social support, and identifying low-cost/convenient opportunities for physical activity.

Abstract
To identify promoters of and barriers to fruit, vegetable, and fast-food consumption, we interviewed low-income African Americans in Philadelphia. Salient promoters and barriers were distinct from each other and differed by food type: taste was a promoter and cost a barrier to all foods; convenience, cravings, and preferences promoted consumption of fast foods; health concerns promoted consumption of fruits and vegetables and avoidance of fast foods. Promoters and barriers differed by gender and age. Strategies for dietary change should consider food type, gender, and age.

Abstract
The theory of planned behavior (TPB) was integrated within the theory of self-care (SCT) to explore the predictive value of extending TPB to measure attitudes and beliefs regarding a behavioral goal, and determine the ability of goal beliefs to predict engagement in the combined, multiple behaviors necessary to control BP. The hypothesized model was evaluated in a sample of 306 community-dwelling African Americans between 21 and 65 years of age. Scales developed for the study achieved acceptable reliability (alpha = .68-.95). Structural equation modeling analysis resulted in a second-order factor structure with attitude, subjective norm, perceived behavioral control, and intention modeled as indicators of a construct representing goal beliefs related to keeping BP within normal limits. This latent construct was conceptualized within the theory of self-care as "self-care motivation," and predicted 18% of the variance in self-care behaviors necessary for BP control. The model achieved acceptable fit (CMIN/df = 2.32; CFI = .95; RMSEA = .066). Final assessment of fit was done using multi-group SEM and bootstrapping techniques. In this extension of the TPB attitudes and beliefs regarding the goal of keeping BP within normal limits were found to determine one's motivation to engage in the multiple behaviors necessary for BP control.

AbstractObjectiveAlthough diet is a modifiable lifestyle factor to reduce abdominal obesity risk, the relationship between the Health Eating Index (HEI) and waist circumference (WC) has not been studied. The present study aimed to describe relationships between the HEI and abdominal obesity among adults.DesignSecondary data analysis of a cross-sectional national survey, the Third National Health and Nutrition Examination Survey (NHANES III). The HEI data, including the total HEI score and HEI component scores, were collected with a 24 h recall. WC measures were taken during a physical examination. Abdominal obesity was defined as WC ≥ 102 cm for men and WC ≥ 88 cm for women. Other covariates were collected during an interview.SubjectsIn total 15 658 US adults, men (n 7470) and non-pregnant women (n 8188).ResultsThe odds of abdominal obesity was 8·3 % (95 % CI 1·8, 14·9 %, P = 0·014) lower for women and 14·5 % (95 % CI 6·8, 21·9 %, P ≤ 0·001) lower for men with each 10-unit increase in total HEI score (HEI scale, 0–100). For each point increase for the fruit score, abdominal obesity risk decreased by 2·6 % (95 % CI 0·8, 4·4 %, P = 0·007) for women. Abdominal obesity risk decreased for men with each point increase in saturated fat and variety scores, by 3·1 % (95 % CI 0·1, 6·0 %, P = 0·042) and 4·0 % (95 % CI 0·1, 7·7 %, P = 0·043) respectively.ConclusionsDietary consumption that follows the HEI is associated with a lower risk for abdominal obesity.

Abstract
Hypertension is a major cause of disease burden in all racial, ethnic, and socioeconomic groups in developing and developed regions and countries. Differences in blood pressure likely begin early in life and reflect a complex relationship of biologic, genetic, social, and environmental interactions. The relationship between socioeconomic status and hypertension is complex and difficult to measure. Instituting lifestyle changes for the primary prevention and treatment of hypertension among the general population would decrease prevalence, improve blood pressure control, and be effective in eliminating many socioeconomic differences in risk factors for cardiovascular disease. Health care providers can potentially impact blood pressure control by incorporating knowledge of socioeconomic factors and mechanisms in care delivery. This review highlights socioeconomic status in the prevalence and incidence of hypertension and identifies contributing factors associated with blood pressure control.

Abstract
The purpose of this study was to develop and conduct preliminary psychometric assessment of instruments measuring knowledge and self-care practices regarding behaviors needed for blood pressure (BP) control among African Americans. Items were empirically derived and scored on a 7-point, bipolar scale. The instruments were evaluated in a sample of 306 community-dwelling African Americans. Results revealed acceptable reliability and validity of the BP Knowledge Scale. Results for the BP Self-Care Scale were mixed. A structural equation model of these scales, recorded BP, and covariates fit well. There was an unexpected positive correlation between self-care and BP suggesting a potential bi-directional relationship. The scales demonstrated acceptable psychometric properties and, with minor revisions, may have clinical utility as measures of BP knowledge and self-care.

Abstract
PURPOSE OF REVIEW The impact of socioeconomic status on hypertension is complicated and unclear. In this article, we review the findings of recently published studies pertaining to the association between socioeconomic status and hypertension. Specifically, we focus on several potentially modifiable modes of pathogenesis involved in this association, including education, occupation, and social environment. We also review several mechanisms through which the effects of socioeconomic status on hypertension may be mediated. RECENT FINDINGS Several modifiable socioeconomic determinants, such as education and occupation, are associated with hypertension. Additional socioeconomic status markers such as urban or rural dwelling and individual, local or national economic conditions are also associated with hypertension, although these associations are complicated and at times somewhat contradictory. Possible explanations for this impact include awareness of hypertension prevention and control and better accessibility and adherence to medical treatment among higher socioeconomic status groups, as well as low birth weight and higher job strain among lower socioeconomic status groups. SUMMARY Low socioeconomic status is associated with higher blood pressure. There is a need to develop and test culturally appropriate interventions to reduce the prevalence of hypertension among these populations to minimize the resultant cardiovascular morbidity and mortality.
