Item Open Access A health literacy pilot intervention to improve medication adherence using Meducation® technology.(Patient education and counseling, 2014-05) Zullig, Leah L; McCant, Felicia; Melnyk, S Dee; Danus, Susanne; Bosworth, Hayden BObjective
To determine whether antihypertensive medication adherence could improve using a Meducation® technology health literacy intervention.Methods
We conducted a six-month feasibility study among patients with cardiovascular disease (CVD) risk factors receiving care from hospital-based primary care clinics. All patients received a personalized Meducation® calendar listing CVD-related medications. We evaluated changes in medication adherence and clinical outcomes at six months.Results
There was a 42% enrollment rate (n=23). Forty percent had low health literacy, defined as less than 9th grade reading level. At three months, self-reported medication adherence improved. At six months, medication possession ratio improved 3.2%. Also, at six months there were decreases in patients' average systolic blood pressure (0.5 mmHg), diastolic blood pressure (1.5 mmHg), and body weight (3.6 pounds) (p>0.05).Conclusions
A health literacy intervention may be a feasible mechanism to improve cardiovascular-related medication adherence and outcomes.Practice implications
Health literacy interventions may improve adherence while requiring relatively few resources to implement.Item Open Access Accelerated epigenetic age as a biomarker of cardiovascular sensitivity to traffic-related air pollution.(Aging, 2020-12) Ward-Caviness, Cavin K; Russell, Armistead G; Weaver, Anne M; Slawsky, Erik; Dhingra, Radhika; Kwee, Lydia Coulter; Jiang, Rong; Neas, Lucas M; Diaz-Sanchez, David; Devlin, Robert B; Cascio, Wayne E; Olden, Kenneth; Hauser, Elizabeth R; Shah, Svati H; Kraus, William EBackground
Accelerated epigenetic age has been proposed as a biomarker of increased aging, which may indicate disruptions in cellular and organ system homeostasis and thus contribute to sensitivity to environmental exposures.Methods
Using 497 participants from the CATHGEN cohort, we evaluated whether accelerated epigenetic aging increases cardiovascular sensitivity to traffic-related air pollution (TRAP) exposure. We used residential proximity to major roadways and source apportioned air pollution models as measures of TRAP exposure, and chose peripheral arterial disease (PAD) and blood pressure as outcomes based on previous associations with TRAP. We used Horvath epigenetic age acceleration (AAD) and phenotypic age acceleration (PhenoAAD) as measures of age acceleration, and adjusted all models for chronological age, race, sex, smoking, and socioeconomic status.Results
We observed significant interactions between TRAP and both AAD and PhenoAAD. Interactions indicated that increased epigenetic age acceleration elevated associations between proximity to roadways and PAD. Interactions were also observed between AAD and gasoline and diesel source apportioned PM2.5.Conclusion
Epigenetic age acceleration may be a biomarker of sensitivity to air pollution, particularly for TRAP in urban cohorts. This presents a novel means by which to understand sensitivity to air pollution and provides a molecular measure of environmental sensitivity.Item Open Access ACE-inhibition increases podocyte number in experimental glomerular disease independent of proliferation.(Journal of the renin-angiotensin-aldosterone system : JRAAS, 2015-06) Zhang, Jiong; Yanez, David; Floege, Anna; Lichtnekert, Julia; Krofft, Ronald D; Liu, Zhi-Hong; Pippin, Jeffrey W; Shankland, Stuart JObjective
The objective of this article is to test the effects of angiotensin-converting enzyme (ACE)-inhibition on glomerular epithelial cell number in an inducible experimental model of focal segmental glomerulosclerosis (FSGS).Background
Although ACE-inhibition has been shown to limit podocyte loss by enhancing survival, little is known about its effect on podocyte number following an abrupt decline in disease.Methods
Experimental FSGS was induced with cytotoxic antipodocyte antibody. Following induction, groups were randomized to receive the ACE-inhibitor enalapril, the smooth muscle relaxant hydralazine (blood pressure control) or drinking water. Blood pressure, kidney function and histology were measured seven and 14 days following disease induction.Results
Both glomerulosclerosis and urinary albumin-to-creatinine ratio were less in the ACE-inhibition arm at day 14. At day 7 of disease, mean podocyte numbers were 26% and 29% lower in the enalapril and hydralazine arms, respectively, compared to normal mice in which no antibody was injected. At day 14, the mean podocyte number was only 18% lower in the enalapril arm, but was 39% lower in the hydralazine arm compared to normal mice. Podocyte proliferation did not occur at any time in any group. Compared to water- or hydralazine-treated mice with FSGS, the enalapril arm had a higher mean number of glomerular parietal epithelial cells that co-expressed the podocyte proteins WT-1 and synaptopodin, as well as phospho-ERK.Conclusion
The results show following an abrupt decline in podocyte number, the initiation of ACE-inhibition but not hydralazine, was accompanied by higher podocyte number in the absence of proliferation. This was accompanied by a higher number of parietal epithelial cells that co-express podocyte proteins. Increasing podocyte number appears to be accompanied by reduced glomerulosclerosis.Item Open Access Addressing Hypertension Outcomes Using Telehealth and Population Health Managers: Adaptations and Implementation Considerations.(Current hypertension reports, 2022-08) Drake, Connor; Lewinski, Allison A; Rader, Abigail; Schexnayder, Julie; Bosworth, Hayden B; Goldstein, Karen M; Gierisch, Jennifer; White-Clark, Courtney; McCant, Felicia; Zullig, Leah LPurpose of review
There is a growing evidence base describing population health approaches to improve blood pressure control. We reviewed emerging trends in hypertension population health management and present implementation considerations from an intervention called Team-supported, Electronic health record-leveraged, Active Management (TEAM). By doing so, we highlight the role of population health managers, practitioners who use population level data and to proactively engage at-risk patients, in improving blood pressure control.Recent findings
Within a population health paradigm, we discuss telehealth-delivered approaches to equitably improve hypertension care delivery. Additionally, we explore implementation considerations and complementary features of team-based, telehealth-delivered, population health management. By leveraging the unique role and expertise of a population health manager as core member of team-based telehealth, health systems can implement a cost-effective and scalable intervention that addresses multi-level barriers to hypertension care delivery. We describe the literature of telehealth-based population health management for patients with hypertension. Using the TEAM intervention as a case study, we then present implementation considerations and intervention adaptations to integrate a population health manager within the health care team and effectively manage hypertension for a defined patient population. We emphasize practical considerations to inform implementation, scaling, and sustainability. We highlight future research directions to advance the field and support translational efforts in diverse clinical and community contexts.Item Open Access Age trajectories of physiological indices in relation to healthy life course.(Mech Ageing Dev, 2011-03) Arbeev, Konstantin G; Ukraintseva, Svetlana V; Akushevich, Igor; Kulminski, Alexander M; Arbeeva, Liubov S; Akushevich, Lucy; Culminskaya, Irina V; Yashin, Anatoliy IWe analysed relationship between the risk of onset of "unhealthy life" (defined as the onset of cancer, cardiovascular diseases, or diabetes) and longitudinal changes in body mass index, diastolic blood pressure, hematocrit, pulse pressure, pulse rate, and serum cholesterol in the Framingham Heart Study (Original Cohort) using the stochastic process model of human mortality and aging. The analyses demonstrate how decline in resistance to stresses and adaptive capacity accompanying human aging can be evaluated from longitudinal data. We showed how these components of the aging process, as well as deviation of the trajectories of physiological indices from those minimising the risk at respective ages, can lead to an increase in the risk of onset of unhealthy life with age. The results indicate the presence of substantial gender difference in aging related decline in stress resistance and adaptive capacity, which can contribute to differences in the shape of the sex-specific patterns of incidence rates of aging related diseases.Item Open Access Association between depression and hypertension using classic and revised blood pressure thresholds.(Family practice, 2020-10) DeMoss, Dustin S; Teigen, Kari J; Claassen, Cynthia A; Fisk, Mandy J; Blair, Somer E; Bakre, Sulaimon A; Hurd, Cheryl L; Rush, Augustus JBackground
In a primary care population, the relationship between treatment of depression and hypertension (HTN) under the recently revised American College of Cardiology and American Heart Association HTN thresholds for diagnosing HTN is unknown.Objective
To compare the association between changes in severity of co-occurring depression and HTN over time using the newly revised versus previous HTN guidelines.Methods
In this retrospective cohort study, outpatients ≥18 years (n = 3018) with clinically significant depressive symptoms and elevated blood pressure at baseline were divided into a 'revised' guideline group (baseline blood pressure ≥130/80 mmHg), a 'classic' guideline group (≥140/90 mmHg) and a 'revised-minus-classic' group (≥130/80 and <140/90 mmHg). Depressive symptom change was assessed using the Patient Health Questionnaire-9 (PHQ-9). Correlations between changes in PHQ-9 scores and HTN levels by group over a 6- to 18-month observation period were assessed using robust regression analysis.Results
There were demographic and clinical differences between groups. A total of 41% of study subjects (1252/3018) had a visit during the follow-up period where additional PHQ-9 and HTN results were available. Depressive symptom change was unrelated to change in blood pressure in the revised and revised-minus-classic groups. The classic HTN group demonstrated a clinically insignificant change in systolic blood pressure for each unit change in PHQ-9 score (β = 0.23, P-value =0.02).Conclusions
Although a statistically significant association between reduced HTN levels and improvement in depressive symptoms was demonstrated under classic HTN guidelines, there was no clinically meaningful association between treatment of depression and improved HTN levels under either guideline.Item Open Access Baseline Antihypertensive Drug Count and Patient Response to Hypertension Medication Management.(Journal of clinical hypertension (Greenwich, Conn.), 2016-04) Crowley, Matthew J; Olsen, Maren K; Woolson, Sandra L; King, Heather A; Oddone, Eugene Z; Bosworth, Hayden BTelemedicine-based medication management improves hypertension control, but has been evaluated primarily in patients with low antihypertensive drug counts. Its impact on patients taking three or more antihypertensive agents is not well-established. To address this evidence gap, the authors conducted an exploratory analysis of an 18-month, 591-patient trial of telemedicine-based hypertension medication management. Using general linear models, the effect of medication management on blood pressure for patients taking two or fewer antihypertensive agents at study baseline vs those taking three or more was compared. While patients taking two or fewer antihypertensive agents had a significant reduction in systolic blood pressure with medication management, those taking three or more had no such response. The between-subgroup effect difference was statistically significant at 6 months (-6.4 mm Hg [95% confidence interval, -12.2 to -0.6]) and near significant at 18 months (-6.0 mm Hg [95% confidence interval, -12.2 to 0.2]). These findings suggest that baseline antihypertensive drug count may impact how patients respond to hypertension medication management and emphasize the need to study management strategies specifically in patients taking three or more antihypertensive medications.Item Open Access Baseline medication adherence and blood pressure in a 24-month longitudinal hypertension study.(Journal of clinical nursing, 2011-11) Shaw, R; Bosworth, HBAim and objectives. We sought to identify the feasibility and predictive validity of an easy and quick self-reported measure of medication adherence and to identify characteristics of people with hypertension that may warrant increase attentiveness by nurses to address hypertensive self-management needs. Background. Current control rates of hypertension are approximately 50%. Effective blood pressure control can be achieved in most people with hypertension through antihypertensive medication. However, hypertension control can only be achieved if the patient is adherent with their medication regimen. Patients who are non-adherent may be in need of additional intervention. Design. This secondary analysis evaluated the systolic blood pressure of patients who received usual hypertension management across 24 months at six-month intervals. Methods. A longitudinal study of 159 hypertensive patients in two primary care clinics. Results. In a sample of 159 patients receiving care in a primary care facility, baseline medication non-adherence was associated with a 6·3 mmHg increase in systolic blood pressure (pItem Unknown Blood pressure control in a hypertension telemedicine intervention: does distance to primary care matter?(Journal of clinical hypertension (Greenwich, Conn.), 2013-10) Bowen, Michael E; Bosworth, Hayden B; Roumie, Christianne LAlthough telemedicine may help overcome geographic access barriers, it is unknown whether rural patients receive greater benefits. In a secondary analysis of 503 veterans participating in a hypertension telemedicine study, the authors hypothesized that patients with greater travel distances would have greater improvements in 18-month systolic blood pressure (SBP). Patients were categorized by telemedicine exposure and travel distance to primary care, derived from zip codes. Comparisons were (1) usual care (UC), distance <30 miles (reference); (2) UC, distance ≥30 miles; (3) telemedicine, distance <30 miles; (4) telemedicine, distance ≥30 miles. Compared with patients receiving UC, distance <30 miles (intercept=127.7), no difference in 18-month SBP was observed in patients receiving UC, distance ≥30 miles (0.13 mm Hg, 95% confidence interval [-6.6 to 6.8]); telemedicine, distance <30 miles (-1.1 mm Hg [-7.3 to 5.2]); telemedicine, distance ≥30 miles (-0.80 mm Hg [-6.6 to 5.1]). Although telemedicine may help overcome geographic access barriers, additional studies are needed to identify patients most likely to benefit.Item Unknown Blood pressure level impacts risk of death among HIV seropositive adults in Kenya: a retrospective analysis of electronic health records.(BMC Infect Dis, 2014-05-22) Bloomfield, Gerald S; Hogan, Joseph W; Keter, Alfred; Holland, Thomas L; Sang, Edwin; Kimaiyo, Sylvester; Velazquez, Eric JBACKGROUND: Mortality among people with human immunodeficiency virus (HIV) infection is increasingly due to non-communicable causes. This has been observed mostly in developed countries and the routine care of HIV infected individuals has now expanded to include attention to cardiovascular risk factors. Cardiovascular risk factors such as high blood pressure are often overlooked among HIV seropositive (+) individuals in sub-Saharan Africa. We aimed to determine the effect of blood pressure on mortality among HIV+ adults in Kenya. METHODS: We performed a retrospective analysis of electronic medical records of a large HIV treatment program in western Kenya between 2005 and 2010. All included individuals were HIV+. We excluded participants with AIDS, who were <16 or >80 years old, or had data out of acceptable ranges. Missing data for key covariates was addressed by inverse probability weighting. Primary outcome measures were crude mortality rate and mortality hazard ratio (HR) using Cox proportional hazards models adjusted for potential confounders including HIV stage. RESULTS: There were 49,475 (74% women) HIV+ individuals who met inclusion and exclusion criteria. Mortality rates for men and women were 3.8 and 1.8/100 person-years, respectively, and highest among those with the lowest blood pressures. Low blood pressure was associated with the highest mortality incidence rate (IR) (systolic <100 mmHg IR 5.2 [4.8-5.7]; diastolic <60 mmHg IR 9.2 [8.3-10.2]). Mortality rate among men with high systolic blood pressure without advanced HIV (3.0, 95% CI: 1.6-5.5) was higher than men with normal systolic blood pressure (1.1, 95% CI: 0.7-1.7). In weighted proportional hazards regression models, men without advanced HIV disease and systolic blood pressure ≥140 mmHg carried a higher mortality risk than normotensive men (HR: 2.39, 95% CI: 0.94-6.08). CONCLUSIONS: Although there has been little attention paid to high blood pressure among HIV+ Africans, we show that blood pressure level among HIV+ patients in Kenya is related to mortality. Low blood pressure carries the highest mortality risk. High systolic blood pressure is associated with mortality among patients whose disease is not advanced. Further investigation is needed into the cause of death for such patients.Item Open Access Blood Pressure Response during Cardiopulmonary Exercise Testing in Heart Failure.(Medicine and science in sports and exercise, 2018-07) Il'giovine, Zachary J; Solomon, Nicole; Devore, Adam D; Wojdyla, Daniel; Patel, Chetan B; Rogers, Joseph GIntroduction
The prognostic value of peak V˙O2 and V˙E/V˙CO2 slope measured during cardiopulmonary exercise (CPX) testing has been well established in patients with advanced heart failure, but blood pressure response to exercise is less well characterized.Methods
We retrospectively studied 151 outpatients who underwent CPX testing as part of an advanced heart failure evaluation. The outcome of interest was failure of medical management, defined by death, cardiac transplantation, or left ventricular assist device placement. Patients were stratified into tertiles by change in systolic blood pressure (SBP) (<13, 13-26, and ≥27 mm Hg) during exercise.Results
Patients in the lowest tertile had the lowest peak V˙O2 (10.2 vs 10.6 vs 13.6 mL·kg·min, P = <0.001), the highest V˙E/V˙CO2 slope (42.8 vs 42.1 vs 36.3, P = 0.030), the shortest mean exercise time (5.1 vs 6.0 vs 7.0 min, P = <0.001), and the highest probability of failure of medical management at 1.5 yr (0.69 vs 0.41 vs 0.34, P = 0.011). After multivariate adjustment, increased SBP <20 mm Hg during exercise was associated with a lower hazard of medical management failure (hazard ratio = 0.96, 95% confidence interval [CI] = 0.934-0.987), whereas SBP increases >20 mm Hg were associated with an increased hazard (hazard ratio = 1.046, 95% CI = 1.018-1.075).Conclusion
In conclusion, changes in SBP during CPX testing provide additional prognostic information above standard clinical variables. The peculiar increase in risk noted in those with a rise in SBP >20 mm Hg is less clear and needs to be investigated further.Item Open Access Critical role of TNF-α in cerebral aneurysm formation and progression to rupture.(J Neuroinflammation, 2014-04-16) Starke, Robert M; Chalouhi, Nohra; Jabbour, Pascal M; Tjoumakaris, Stavropoula I; Gonzalez, L Fernando; Rosenwasser, Robert H; Wada, Kosuke; Shimada, Kenji; Hasan, David M; Greig, Nigel H; Owens, Gary K; Dumont, Aaron SBACKGROUND: Alterations in TNF-α expression have been associated with cerebral aneurysms, but a direct role in formation, progression, and rupture has not been established. METHODS: Cerebral aneurysms were induced through hypertension and a single stereotactic injection of elastase into the basal cistern in mice. To test the role of TNF-α in aneurysm formation, aneurysms were induced in TNF-α knockout mice and mice pretreated with the synthesized TNF-α inhibitor 3,6'dithiothalidomide (DTH). To assess the role of TNF-α in aneurysm progression and rupture, DTH was started 6 days after aneurysm induction. TNF-α expression was assessed through real-time PCR and immunofluorescence staining. RESULTS: TNF-α knockout mice and those pre-treated with DTH had significantly decreased incidence of aneurysm formation and rupture as compared to sham mice. As compared with sham mice, TNF-α protein and mRNA expression was not significantly different in TNF-α knockout mice or those pre-treated with DTH, but was elevated in unruptured and furthermore in ruptured aneurysms. Subarachnoid hemorrhage (SAH) occurred between 7 and 21 days following aneurysm induction. To ensure aneurysm formation preceded rupture, additional mice underwent induction and sacrifice after 7 days. Seventy-five percent had aneurysm formation without evidence of SAH. Initiation of DTH treatment 6 days after aneurysm induction did not alter the incidence of aneurysm formation, but resulted in aneurysmal stabilization and a significant decrease in rupture. CONCLUSIONS: These data suggest a critical role of TNF-α in the formation and rupture of aneurysms in a model of cerebral aneurysm formation. Inhibitors of TNF-α could be beneficial in preventing aneurysmal progression and rupture.Item Open Access Decongestion strategies and renin-angiotensin-aldosterone system activation in acute heart failure.(JACC Heart Fail, 2015-02) Mentz, Robert J; Stevens, Susanna R; DeVore, Adam D; Lala, Anuradha; Vader, Justin M; AbouEzzeddine, Omar F; Khazanie, Prateeti; Redfield, Margaret M; Stevenson, Lynne W; O'Connor, Christopher M; Goldsmith, Steven R; Bart, Bradley A; Anstrom, Kevin J; Hernandez, Adrian F; Braunwald, Eugene; Felker, G MichaelOBJECTIVES: The purpose of this study was to assess the relationship between biomarkers of renin-angiotensin-aldosterone system (RAAS) activation and decongestion strategies, worsening renal function, and clinical outcomes. BACKGROUND: High-dose diuretic therapy in patients with acute heart failure (AHF) is thought to activate the RAAS; and alternative decongestion strategies, such as ultrafiltration (UF), have been proposed to mitigate this RAAS activation. METHODS: This study analyzed 427 AHF patients enrolled in the DOSE-AHF (Diuretic Optimization Strategies in Acute Heart Failure) and CARRESS-HF (Cardiorenal Rescue Study in Acute Decompensated Heart Failure) trials. We assessed the relationship between 2 markers of RAAS activation (plasma renin activity [PRA] and aldosterone) from baseline to 72 h and 96 h and decongestion strategy: high- versus low-dose and continuous infusion versus bolus furosemide for DOSE-AHF and UF versus stepped pharmacologic care for CARRESS-HF. We determined the relationships between RAAS biomarkers and 60-day outcomes. RESULTS: Patients with greater RAAS activation at baseline had lower blood pressures, lower serum sodium levels, and higher blood urea nitrogen (BUN) concentration. Continuous infusion furosemide and UF were associated with greater PRA increases (median: +1.66 vs. +0.66 ng/ml/h with continuous vs. bolus infusion, respectively, p = 0.021; +4.05 vs. +0.56 ng/ml/h with UF vs. stepped care, respectively, p = 0.014). There were no significant differences in RAAS biomarker changes with high- versus low-dose diuretic therapy (both: p > 0.5). Neither baseline log PRA nor log aldosterone was associated with increased death or HF hospitalization (hazard ratio [HR] for a doubling of 1.05; 95% confidence interval [CI]: 0.98 to 1.13; p = 0.18; and HR: 1.13; 95% CI: 0.99 to 1.28; p = 0.069, respectively). The change in RAAS biomarkers from baseline to 72 and 96 h was not associated with outcomes (both: p > 0.5). CONCLUSIONS: High-dose loop diuretic therapy did not result in RAAS activation greater than that with low-dose diuretic therapy. UF resulted in greater PRA increase than stepped pharmacologic care. Neither PRA nor aldosterone was significantly associated with short-term outcomes in this cohort. (Determining Optimal Dose and Duration of Diuretic Treatment in People With Acute Heart Failure [DOSE-AHF]; NCT00577135; Effectiveness of Ultrafiltration in Treating People With Acute Decompensated Heart Failure and Cardiorenal Syndrome [CARRESS]; NCT00608491).Item Open Access Effects of adult age and blood pressure on executive function and speed of processing.(Experimental aging research, 2010-04) Bucur, Barbara; Madden, David JPrevious research has established that the effects of chronically increased blood pressure (BP) on cognition interact with adult age, but the relevant cognitive processes are not well defined. In this cross-sectional study, using a sample matched for age, years of education, and sex, 134 individuals with either normal BP (n = 71) or chronically high BP (n = 63) were categorized into younger (19-39 years), middle-aged (41-58 years), and older (60-79 years) groups. Using a between-subjects analysis of variance (ANOVA), covarying for race and years of education, composite measures of executive function and perceptual speed both exhibited age-related decline. The executive function measure, however, was associated with a differential decline in high BP older adults. This result held even when the executive function scores were covaried for speed, demonstrating an independent, age-related effect of higher BP on executive function.Item Open Access Evaluation and Management of Pulmonary Hypertension in Noncardiac Surgery: A Scientific Statement From the American Heart Association.(Circulation, 2023-04) Rajagopal, Sudarshan; Ruetzler, Kurt; Ghadimi, Kamrouz; Horn, Evelyn M; Kelava, Marta; Kudelko, Kristina T; Moreno-Duarte, Ingrid; Preston, Ioana; Rose Bovino, Leonie L; Smilowitz, Nathaniel R; Vaidya, Anjali; American Heart Association Council on Cardiopulmonary, Critical Care, Perioperative and Resuscitation, and the Council on Cardiovascular and Stroke NursingPulmonary hypertension, defined as an elevation in blood pressure in the pulmonary arteries, is associated with an increased risk of death. The prevalence of pulmonary hypertension is increasing, with an aging population, a rising prevalence of heart and lung disease, and improved pulmonary hypertension survival with targeted therapies. Patients with pulmonary hypertension frequently require noncardiac surgery, although pulmonary hypertension is associated with excess perioperative morbidity and death. This scientific statement provides guidance on the evaluation and management of pulmonary hypertension in patients undergoing noncardiac surgery. We advocate for a multistep process focused on (1) classification of pulmonary hypertension group to define the underlying pathology; (2) preoperative risk assessment that will guide surgical decision-making; (3) pulmonary hypertension optimization before surgery to reduce perioperative risk; (4) intraoperative management of pulmonary hypertension to avoid right ventricular dysfunction and to maintain cardiac output; and (5) postoperative management of pulmonary hypertension to ensure recovery from surgery. Last, this scientific statement highlights the paucity of evidence to support perioperative pulmonary hypertension management and identifies areas of uncertainty and opportunities for future investigation.Item Open Access Factors associated with non-adherence to three hypertension self-management behaviors: preliminary data for a new instrument.(Journal of general internal medicine, 2013-01) Crowley, Matthew J; Grubber, Janet M; Olsen, Maren K; Bosworth, Hayden BBackground
Clinicians have difficulty in identifying patients that are unlikely to adhere to hypertension self-management. Identifying non-adherence is essential to addressing suboptimal blood pressure control and high costs.Objectives
1) To identify risk factors associated with non-adherence to three key self-management behaviors in patients with hypertension: proper medication use, diet, and exercise; 2) To evaluate the extent to which an instrument designed to identify the number of risk factors present for non-adherence to each of the three hypertension self-management behaviors would be associated with self-management non-adherence and blood pressure.Design
Cross-sectional analysis of randomized trial data.Patients
Six hundred and thirty-six primary care patients with hypertension.Measurements
1) Demographic, socioeconomic, psychosocial, and health belief-related factors; 2) measures of self-reported adherence to recommended medication use, diet recommendations, and exercise recommendations, all collected at baseline assessment; 3) systolic blood pressure (SBP) and diastolic blood pressure (DBP).Results
We identified patient factors associated with measures of non-adherence to medications, diet, and exercise in hypertension. We then combined risk factors associated with ≥1 adherence measure into an instrument that generated three composite variables (medication, diet, and exercise composites), reflecting the number of risk factors present for non-adherence to the corresponding self-management behavior. These composite variables identified subgroups with higher likelihood of medication non-adherence, difficulty following diet recommendations, and difficulty following exercise recommendations. Composite variable levels representing the highest number of self-management non-adherence risk factors were associated with higher SBP and DBP.Conclusions
We identified factors associated with measures of non-adherence to recommended medication use, diet, and exercise in hypertension. We then developed an instrument that was associated with non-adherence to these self-management behaviors, as well as with blood pressure. With further study, this instrument has potential to improve identification of non-adherent patients with hypertension.Item Open Access Hair cortisol as a biomarker of stress in mindfulness training for smokers.(J Altern Complement Med, 2014-08) Goldberg, Simon B; Manley, Alison R; Smith, Stevens S; Greeson, Jeffrey M; Russell, Evan; Van Uum, Stan; Koren, Gideon; Davis, James MOBJECTIVES: Stress is a well-known predictor of smoking relapse, and cortisol is a primary biomarker of stress. The current pilot study examined changes in levels of cortisol in hair within the context of two time-intensity matched behavioral smoking cessation treatments: mindfulness training for smokers and a cognitive-behavioral comparison group. PARTICIPANTS: Eighteen participants were recruited from a larger randomized controlled trial of smoking cessation. OUTCOME MEASURES: Hair samples (3 cm) were obtained 1 month after quit attempt, allowing for a retrospective analysis of hair cortisol at preintervention and post-quit attempt time periods. Self-reported negative affect was also assessed before and after treatment. INTERVENTION: Both groups received a 7-week intensive intervention using mindfulness or cognitive-behavioral strategies. RESULTS: Cortisol significantly decreased from baseline to 1 month after quit attempt in the entire sample (d=-0.35; p=.005). In subsequent repeated-measures analysis of variance models, time by group and time by quit status interaction effects were not significant. However, post hoc paired t tests yielded significant pre-post effects among those randomly assigned to the mindfulness condition (d=-0.48; p=.018) and in those abstinent at post-test (d=-0.41; p=.004). Decreased hair cortisol correlated with reduced negative affect (r=.60; p=.011). CONCLUSIONS: These preliminary findings suggest that smoking cessation intervention is associated with decreased hair cortisol levels and that reduced hair cortisol may be specifically associated with mindfulness training and smoking abstinence. RESULTS support the use of hair cortisol as a novel objective biomarker in future research.Item Open Access Health and function of participants in the Long Life Family Study: A comparison with other cohorts.(Aging (Albany NY), 2011-01) Newman, Anne B; Glynn, Nancy W; Taylor, Christopher A; Sebastiani, Paola; Perls, Thomas T; Mayeux, Richard; Christensen, Kaare; Zmuda, Joseph M; Barral, Sandra; Lee, Joseph H; Simonsick, Eleanor M; Walston, Jeremy D; Yashin, Anatoli I; Hadley, EvanIndividuals from families recruited for the Long Life Family Study (LLFS) (n= 4559) were examined and compared to individuals from other cohorts to determine whether the recruitment targeting longevity resulted in a cohort of individuals with better health and function. Other cohorts with similar data included the Cardiovascular Health Study, the Framingham Heart Study, and the New England Centenarian Study. Diabetes, chronic pulmonary disease and peripheral artery disease tended to be less common in LLFS probands and offspring compared to similar aged persons in the other cohorts. Pulse pressure and triglycerides were lower, high density lipids were higher, and a perceptual speed task and gait speed were better in LLFS. Age-specific comparisons showed differences that would be consistent with a higher peak, later onset of decline or slower rate of change across age in LLFS participants. These findings suggest several priority phenotypes for inclusion in future genetic analysis to identify loci contributing to exceptional survival.Item Open Access Heart matters: Gender and racial differences cardiovascular disease risk factor control among veterans.(Women's health issues : official publication of the Jacobs Institute of Women's Health, 2014-09) Goldstein, Karen M; Melnyk, S Dee; Zullig, Leah L; Stechuchak, Karen M; Oddone, Eugene; Bastian, Lori A; Rakley, Susan; Olsen, Maren K; Bosworth, Hayden BBackground
Cardiovascular disease (CVD) is the leading cause of mortality for U.S. women. Racial minorities are a particularly vulnerable population. The increasing female veteran population has an higher prevalence of certain cardiovascular risk factors compared with non-veteran women; however, little is known about gender and racial differences in cardiovascular risk factor control among veterans.Methods
We used analysis of variance, adjusting for age, to compare gender and racial differences in three risk factors that predispose to CVD (diabetes, hypertension, and hyperlipidemia) in a cohort of high-risk veterans eligible for enrollment in a clinical trial, including 23,955 men and 1,010 women.Findings
Low-density lipoprotein (LDL) values were higher in women veterans than men with age-adjusted estimated mean values of 111.7 versus 97.6 mg/dL (p < .01). Blood pressures (BPs) were higher among African-American than White female veterans with age-adjusted estimated mean systolic BPs of 136.3 versus 133.5 mmHg, respectively (p < .01), and diastolic BPs of 82.4 versus 78.9 mmHg (p < .01). African-American veterans with diabetes had worse BP, LDL values, and hemoglobin A1c levels, although the differences were only significant among men.Conclusions
Female veterans have higher LDL cholesterol levels than male veterans and African-American veterans have higher BP, LDL cholesterol, and A1c levels than Whites after adjusting for age. Further examination of CVD gender and racial disparities in this population may help to develop targeted treatments and strategies applicable to the general population.Item Open Access Home blood pressure management and improved blood pressure control: results from a randomized controlled trial.(Archives of internal medicine, 2011-07) Bosworth, Hayden B; Powers, Benjamin J; Olsen, Maren K; McCant, Felicia; Grubber, Janet; Smith, Valerie; Gentry, Pamela W; Rose, Cynthia; Van Houtven, Courtney; Wang, Virginia; Goldstein, Mary K; Oddone, Eugene ZBackground
To determine which of 3 interventions was most effective in improving blood pressure (BP) control, we performed a 4-arm randomized trial with 18-month follow-up at the primary care clinics at a Veterans Affairs Medical Center.Methods
Eligible patients were randomized to either usual care or 1 of 3 telephone-based intervention groups: (1) nurse-administered behavioral management, (2) nurse- and physician-administered medication management, or (3) a combination of both. Of the 1551 eligible patients, 593 individuals were randomized; 48% were African American. The intervention telephone calls were triggered based on home BP values transmitted via telemonitoring devices. Behavioral management involved promotion of health behaviors. Medication management involved adjustment of medications by a study physician and nurse based on hypertension treatment guidelines.Results
The primary outcome was change in BP control measured at 6-month intervals over 18 months. Both the behavioral management and medication management alone showed significant improvements at 12 months-12.8% (95% confidence interval [CI], 1.6%-24.1%) and 12.5% (95% CI, 1.3%-23.6%), respectively-but not at 18 months. In subgroup analyses, among those with poor baseline BP control, systolic BP decreased in the combined intervention group by 14.8 mm Hg (95% CI, -21.8 to -7.8 mm Hg) at 12 months and 8.0 mm Hg (95% CI, -15.5 to -0.5 mm Hg) at 18 months, relative to usual care.Conclusions
Overall intervention effects were moderate, but among individuals with poor BP control at baseline, the effects were larger. This study indicates the importance of identifying individuals most likely to benefit from potentially resource intensive programs.Trial registration
