Exploring Cytokine Networks in Resistant Hypertension.

BACKGROUND: Controlling high blood pressure (BP) continues to be a major concern because the associated complications can lead to an increased risk of heart, brain, and kidney disease. Those with hypertension, despite lifestyle and diet modifications and pharmacotherapy, defined as resistant hypertension, are at increased risk for further risk for morbidity and mortality. Understanding inflammation in this population may provide novel avenues for treatment. OBJECTIVES: This study aimed to examine a broad range of cytokines in adults with cardiovascular disease and identify specific cytokines associated with resistant hypertension. METHODS: A secondary data analysis was conducted. The parent study included 156 adults with a history of myocardial infarction within the past 3-7 years and with a multiplex plasma analysis yielding a cytokine panel. A network analysis with lasso penalization for sparsity was performed to explore associations between cytokines and BP. Associated network centrality measures by cytokine were produced, and a community graph was extracted. A sensitivity analysis BP was also performed. RESULTS: Cytokines with larger node strength measures were sTNFR2 and CX3. The graphical network highlighted six cytokines strongly associated with resistant hypertension. Cytokines IL-29 and CCL3 were found to be negatively associated with resistant hypertension, whereas CXCL12, MMP3, sCD163, and sIL6Rb were positively associated with resistant hypertension. DISCUSSION: Understanding the network of associations through exploring oxidative stress and vascular inflammation may provide insight into treatment approaches for resistant hypertension.

Self-management program and Black women with hypertension: Randomized controlled trial substudy.

The prevalence of hypertension (HTN) among Black women in the United States has increased over the past 10 years with a decline in levels of HTN awareness, treatment, and control. Higher death rates occur in Black women from HTN-related diseases when compared with women of other racial/ethnic groups. Although interventions aimed at self-care/self-management are vital to adults becoming the cornerstone of their own health and well-being, there is a paucity of research in Black women. This randomized controlled pilot trial substudy examined the influence of a Chronic Disease Self-Management Program (CDSMP) with tailored coaching versus the CDSMP alone on blood pressure (BP), weight, and scores on self-care questionnaires and medication adherence for Black women with HTN over 9 months. Eighty-three women who had completed the CDSMP were randomly assigned to coaching or no coaching. Median age was 54 years and the time since the HTN diagnosis was 9 years. Significant differences were noted in self-care maintenance and management over time with better self-care in the treatment group. Though not significant, both groups denoted a trend toward better medication adherence. Almost 60% of the participants in both groups showed improvements in their systolic and/or diastolic BP. However, there was no significant difference between the study groups' BP and weight variables. The CDSMP was effective in decreasing BP and improving medication adherence. Further research is needed to evaluate effective coaching strategies that motivate Black women with HTN toward self-care management.

Fatigue, Stress, and Blood Pressure Medication Adherence by Race After Myocardial Infarction.

Fatigue and stress may affect medication adherence. This study explored fatigue, stress, and blood pressure (BP) medication adherence in Black and White adults (N= 152) who had experienced a myocardial infarction. Over half of the sample (55%) reported fatigue as moderate to severe. The regression model explained up to 40% of the variance (p < .001) with fatigue and race significantly predicting adherence. Black participants reported fatigue causing distress (r =.40), and White participants reported greater association of fatigue severity-related BP medication adherence (r =.49). Our findings support considering racial differences when evaluating fatigue associated with BP medication adherence.

Factors Associated With Myocardial Infarction Reoccurrence.

BACKGROUND: As recurrent myocardial infarctions (MIRs) constitute almost a third of the annual incidence of myocardial infarction, identifying the traditional and novel variables related to MIR is important. OBJECTIVE: The aim of this study was to examine modifiable cardiac risks, adiposity, symptoms associated with inflammation (fatigue, depression, sleep) and inflammatory cytokines, and MIR by sex and race. METHODS: Using a cross-sectional descriptive design, we recruited a convenience sample of adults (N = 156) discharged with first myocardial infarction or had MIR in the last 3 to 7 years. Surveys measured demographics, cardiac risk factors, depression, sleep, and fatigue. Anthropometric measures and cytokines tumor necrosis factor-α, interleukin-6, and high-sensitivity C-reactive protein (hsCRP) were obtained. A maximum likelihood regression was calculated to predict MIR. RESULTS: The sample included 57% male and 30% Black participants, and the mean (SD) age was 65 (12) years. The hsCRP was the only cytokine related to symptoms: fatigue ( r = 0.309, P < .001) and depression ( r = 0.255, P = .002). An MIR was not associated with race despite White participants reporting better sleep ( t146 = -3.25, P = .002), lower body mass index ( t154 = -3.49, P = .001), and fewer modifiable risk factors ( t152 = -2.05, P = .04). An MIR was associated with being male, higher hsCRP and tumor necrosis factor-α levels ( P < .001), and higher inflammatory symptoms of fatigue ( P = .04), depression ( P = .01), and poor sleep ( P < .001). CONCLUSION: Further examination of biomarkers to understand the mechanisms associated with inflammatory symptoms of fatigue, depression, and poor sleep and MIR is needed.

Influencing Factors of Inflammatory Bowel Disease-Fatigue: A Path Analysis Model.

BACKGROUND: Fatigue is a common symptom in adults with inflammatory bowel disease (IBD) and is influenced by many physiological, psychological, and situational factors. However, the influencing factors of fatigue associated with IBD have not been evaluated. OBJECTIVE: This study aims to examine factors associated with fatigue during IBD and develop a parsimonious model that describes the influencing factors of fatigue. METHODS: The study was a secondary analysis of cross-sectional data obtained from IBD Partners, an online cohort of adults with the disease, including 12,053 eligible participants. Data were collected using the Patient-Reported Outcomes Measurement Information System short-form scales measuring fatigue, sleep disturbances, pain interference, anxiety, depression, and satisfaction with social roles. Physical activity was measured using a single question. Demographic and clinical variables were collected. Path analysis was computed to identify the direct and indirect effects of situational, physiological, and psychological factors on IBD-fatigue based on the middle range theory of unpleasant symptoms' conceptual framework. RESULTS: Most of the participants were White females. The data best fit a model with situational factors (physical activity and satisfaction with social roles as the mediators). The direct effect of IBD activity, age, sleep disturbances, pain interference, anxiety, and depression on IBD-fatigue was significant. Significant indirect effects were noted on IBD-fatigue from sleep disturbances, pain interference, and depression via physical activity and satisfaction with social roles. DISCUSSION: The study identified two important intervening variables from the tested model. In addition, other symptoms such as sleep, pain, anxiety, and depression are essential and also influence IBD-fatigue.

Life-space constriction in aging adults.

BACKGROUND: Early indicators of declining function and frailty, such as life-space constriction (LSC), are important in identifying those at risk for frailty. PURPOSE: Examine factors associated with LSC and the influence on function and frailty. METHODS: A cross-sectional, descriptive study was conducted using a convenience sample of community dwelling persons 55 and older living in the South. RESULTS: Most participants (N = 72) were female (69%; n = 50) and half were White (53.5%; n = 38). Individual factors including challenges (age-related physiological changes, disease burden, mental health limitations) and buoy (assistive devices, and other compensatory strategies) explained 22% variance in self-reported frailty (F = 3.099 (6, 65); p = .01). LSC explained 34% variance in function (F = 3.805 (8, 59); p = .001) when environmental supports (family ties, and social network) and challenges (area deprivation, built environment, and social disorganization) and individual factors were controlled for. Number of assistive devices was the only significant predictor of frailty.

Comparing comorbidity measures and fatigue post myocardial infarction.

PURPOSE/AIMS: The purpose of this study was to examine comorbidity measures that may relate to the symptom of fatigue post MI: self-reported comorbidities, medication-validated comorbidities, weighted comorbidities for fatigue, and number of comorbidities. DESIGN: Using a cross sectional design, we interviewed a convenience sample of 98 adults, 65 and older, who were 6 to 8 months post myocardial infarction. METHODS: Participants self-reported their comorbidities using a list of 23 comorbid conditions. All medications were visually inspected, and medications were reviewed by a geriatric pharmacist for a common side effect of fatigue. The Revised Piper Fatigue Scale was used to measure fatigue. RESULTS: The mean age of the participants was 76 (SD = 6.3), and most of the sample were White (84%). Neither medication-validated comorbidities nor those medications with fatigue as a common side effect explained fatigue. When controlling for age, sex, and marital status, self-reported comorbidities explained 10% of the variance in fatigue (F (4, 93) = 2.65; p = 0.04). Having 5 or more self-reported comorbidities explained 7% of variance in fatigue scores (F (1, 96) = 7.53; p = 0.007). CONCLUSION: Comorbidities are associated with fatigue post MI. Adults post MI with 5 or more comorbidities should be screened for fatigue.

Coping with Intradialytic Events and Stress Associated with Hemodialysis.

Intradialytic events (IDEs), such as cramping, loss of consciousness, bleeding, and allergic reactions, are major stressors for persons on hemodialysis (HD). This study examined the association between coping strategies and stress associated with HD in persons who have experienced an IDE. Using a cross-sectional correlation design, a convenience sample of patients (N=73) completed a Hemodialysis Demographic Form, Ways of Coping Questionnaire, and a Hemodialysis Stress Visual Analog Scale. Most participants were African American (95%), male (52%), with a mean age of 57 (SD=11.98) years, and an average of 41 (SD=31.55) months on HD. Coping strategies explained 34% of the variance in stress associated with HD (F [11, 61] = 2.89; p=0.004); positive reappraisal and planful problem solving were negatively correlated with stress. Emotion-focused coping strategies were used most during an IDE.

Low-salt diet adherence in African Americans with hypertension.

AIMS AND OBJECTIVES: To identify health and physiological measures, depressive symptoms and locus of control (LOC) in adherence to a low salt (1,500 mg sodium), diet in African American (AA) adults with hypertension (HTN). BACKGROUND: Adherence determinants to self-management behaviours among AA adults with HTN is essential in prevention of outcomes such as stroke. A low-salt diet is one key factor in the successful management of HTN. DESIGN: A cross-sectional correlational design. METHODS: Systolic blood pressure, co-morbidities, serum creatinine, potassium, education, depression, LOC and social support were examined in relationship to self-reported adherence to a low-salt diet in a sample of AA adults (N = 77) aged 55-84. Demographic and physiologic data were collected in addition to diet adherence on a 100 mm visual analog scale. Standardised tools included Multidimensional Health LOC scale and the Patient Health Question-9 Depression Instrument. RESULTS: Lower adherence to a low-salt diet was more prevalent in females (n = 27; 73%). A moderate negative correlation (r = -0.294; p < 0.01) was found with low-salt diet adherence in the PHQ-9 (r = -0.294; p < 0.01). Both multiple regression, models significantly influenced adherence to low salt diet, with both models explaining 24% of the variance; internal LOC (F = 2.599 [8, 68]; p = 0.02) and external LOC (F = 2.667 [8, 68]; p = 0.013). CONCLUSION: Increasing awareness of factors affecting adherence to a low-salt diet is important for clinicians for effective management of HTN in AA adults. RELEVANCE TO CLINICAL PRACTICE: Nurses are encouraged to adopt a comprehensive assessment of those with HTN to identify psychosocial needs, in particular depressive symptoms, as a potential secondary prevention measure.

Factors associated with physical activity in African Americans with hypertension.

BACKGROUND: Pharmacological management only controls 58% of those with hypertension. Combining pharmacological therapy with physical activity is important in controlling hypertension. AIM: To examine factors associated with physical activity (PA) adherence in African Americans (AAs) with hypertension and antihypertensive medication adherence. METHODS: A cross-sectional descriptive correlational design was used to examine if systolic BP, co-morbidities, serum creatinine and potassium, education, depression, locus of control, and social support explained PA adherence in a convenience sample of AAs (N = 77) aged 55 to 84. All completed: demographic data, PA visual analog scale (VAS-PA); Multidimensional Health Locus of Control Scale; Patient Health Question-9 Depression Instrument. Physiological data and co-morbidities were also collected. RESULTS: A third (n = 26) had systolic BP over 140 mm/Hg. The model explained 26% variance in adherence to PA (F = 3.378 [8, 68]; p = .003) with creatinine (p < .05), depression (p < .01), and social support (p < .05) as significant. Differences in VAS-PA scores between levels of depression were significant (F = 4.707 [269], p = .012; Eta2 = 0.12). Those with no depression had significantly higher PA adherence (M = 88.26, SD = 18.97) compared to mildly depressed (M = 70.24, SD 27.71) and moderately depressed (M = 66.83, SD = 23.31). CONCLUSIONS: Clinicians should promote PA as an adjunct to medications for effective control of hypertension in AAs. Screening and intervening for depression are important when examining adherence to PA in AAs with hypertension.

Effects of Tactile Desensitization on Postoperative Pain After Amputation Surgery.

PURPOSE: Pain in the acute setting after amputation is complex with multiple types of pain experienced, including somatic and neuropathic. No studies have measured multiple pain control modalities while using self-management techniques for acute amputation pain. Desensitization could provide a means of pain control for somatic and neuropathic pain. The purpose of this study was to test the efficacious use and effects of tactile desensitization in managing acute postoperative pain after lower limb amputation. DESIGN: This was a pre-experimental repeated measure study. METHODS: Pain description, intensity, anxiety, depression, and medication usage were measured during repeated time periods. Pain intensity was measured before and after each intervention along with efficacy. FINDINGS: Of the times the intervention was self-administered (n = 50) there was a statistically significant reduction in the pain level (P < .001) with large effect sizes for all paired comparisons. Participants found the intervention efficacious and feasible to use. CONCLUSIONS: The findings support a reduction in pain intensity scores using pain medication coupled with tactile desensitization.

Predicting Heart Failure Readmissions.

OBJECTIVES: In this study, the effects of sociodemographic and clinical factors on heart failure (HF) readmission risk were examined. BACKGROUND: Hospitals now incur financial penalties for excessive HF readmission rates; therefore, identifying factors associated with risk is essential for designing risk-reduction strategies. METHODS: A retrospective cohort study using chart reviews compared HF inpatients (N = 245) who were readmitted with those who were not readmitted. RESULTS: The sample included mostly white (64%) elderly (mean [SD] age, 69.8 [15.1] years) men (49%) and women (51%). Using Cox regression, the number of comorbidities (3-4 or 5-8) and type of comorbidities, specifically renal insufficiency (readmission ratio [RR], 1.7; P = .003), atrial fibrillation (RR, 1.7; P = .005), cardiomyopathy (RR, 1.5; P = .020), followed by a history of myocardial infarction/coronary artery disease (RR, 1.4; P = .055), were the predictors of HF readmission. CONCLUSIONS: Targeting those with high-risk comorbidities is important in designing measures to prevent or delay readmission of HF patients.

Seasonal Incidence of Emergent Coronary Artery Bypass Grafting Surgery.

BACKGROUND: Emergent coronary artery bypass grafting (CABG) surgery is often required in the case of severe coronary artery disease, which is refractory to traditional management. The objective of our study was to test the hypothesis that there is seasonal variation in the incidence of emergent CABG. METHODS: A sinusoidal logistic regression model was used to analyze operative data at our cardiovascular institute of 270 cases spanning 5939 calendar days. RESULTS: A cyclic peak risk for emergent CABG was observed for late winter (calendar day 66; P = .036). The odds ratios for the 1-, 2- and 3-month window surrounding this peak were 1.8 (95% CI = 0.94-3.5, P = .072), 1.6 (95% CI = 1.06-2.5, P = .024) and 1.4 (95% CI = 0.9-1.8, P = .066), respectively. CONCLUSION: Our results suggest that a seasonal variation may exist in the incidence of patients presenting with severe coronary artery disease requiring emergent CABG. This information is useful in the scheduling of hospital resources and staff. It also provides important etiology clues underlying coronary artery disease that may lead to future interventions or targeted therapies.

Predictors of depression in black women with hypertension.

Black women have the highest prevalence of hypertension in the world, and depression is associated with both hypertension and lack of health promoting behaviors. Thus, it is important to identify factors that may contribute to depression in hypertensive women. This cross-sectional study was conducted with a convenience sample of 80 black women ages 18-60 who were prescribed anti-hypertensive medication. Data were collected using self-report instruments. The study showed that lower income level, greater number of comorbidities, lower active coping scores, and poorer medication adherence were significantly associated with higher depression scores. These findings have important implications for the development of screening protocols and interventions for black women.

Use of coaching and technology to improve blood pressure control in Black women with hypertension: Pilot randomized controlled trial study.

Hypertension is the main cause of cardiovascular disease, especially in women. Black women (58%) are affected by higher rates of hypertension than other racial/ethnic groups contributing to increased cardio-metabolic disorders. To decrease blood pressure (BP) in this population, a pilot randomized controlled trial was conducted to examine the effects of Interactive Technology Enhanced Coaching (ITEC) versus Interactive Technology (IT) alone in achieving BP control, adherence to antihypertensive medication, and adherence to lifestyle modifications among Black women diagnosed with and receiving medication for their hypertension. Participants completed a 6-week Chronic Disease Self-Management Program (CDSMP), and 83 participants were randomly assigned to ITEC versus IT. Participants were trained to use three wireless tools and five apps that were synchronized to smartphones to monitor BP, weight, physical activity (steps), diet (caloric and sodium intake), and medication adherence. Fitbit Plus, a cloud-based collaborative care platform was used to collect, track, and store data. Using a mixed-effects repeated measures model, the main effect of group means indicated no significant difference between the treatment and referent groups on study variables. The main effect of time indicated significant differences between repeated measures for systolic BP (p < .0001), weight (p < .0001), and steps (p = .018). An interaction effect revealed differences over time and was significant for study measures except diastolic BP. An important goal of this preliminary analysis is to help Black women prioritize self-care management in their everyday environment. Future research is warranted in a geographically broader population of hypertensive Black women.

Fatigue, Depression, Cardiovascular Risk, and Self-Rated Health: Comparing a Community Sample of Adults to Those With a History of Myocardial Infarction.

This cross-sectional descriptive study was designed to compare fatigue, depression, cardiovascular risk, and self-rated health in community dwelling adults (CDA) without a history of myocardial infarction (MI) compared to adults who had experienced an MI 3 to 7 years ago. A convenience sample (n = 40) of CDA completed: demographic health form, Revised Piper Fatigue Scale, and CES-D. Age-matched controls (n = 40) were randomly selected from the Recurrence of Myocardial Infarction (ROMI) study. Most (N = 80) were White (66%) with a mean age of 58.3 (SD = 11.5; range 21-83). The ROMI group reported more diabetes, hypercholesterolemia, obesity, and hypertension, and had higher fatigue (t(61) = 4.51, p < .001). No differences were noted in depression scores (p = .952). Higher fatigue and depression scores were correlated with poorer self-rated health: r = .544 (p < .001) and r = .295 (p = .008).

An integrative review of physical activity in adults with inflammatory bowel disease.

Adults with inflammatory bowel disease (IBD) search for self-management strategies to manage their symptoms and improve their quality of life (QOL). Physical activity (PA) is one of the self-management strategies widely adopted by adults with IBD. This integrative review aimed to synthesize the evidence on health outcomes of PA in adults with IBD as well as to identify the barriers to engaging in PA. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), published literature was searched to identify the articles that addressed PA in adults with IBD. Twenty-eight articles met the inclusion criteria. Many of the reviewed studies used the terms of PA and exercise interchangeably. Walking was the most common PA reported in the studies. The findings from the majority of the reviewed studies supported the benefits of moderate-intensity exercise/PA among adults with IBD. The reviewed studies noted the following positive health outcomes of PA: improvement in QOL, mental health, sleep quality, gastrointestinal symptoms, fatigue and cardiorespiratory fitness. More importantly, participation in PA reduced the risk for development of IBD and the risk for future active disease. The findings from the reviewed studies highlighted the following barriers to engage in PA: fatigue, joint pain, abdominal pain, bowel urgency, active disease and depression.

Living with an Insertable Cardiac Monitor: Influences on Self-Care Management.

The insertable cardiac monitor (ICM) is technology for diagnosing cardiac arrhythmias. The perception of those living with the device and how this relates to self-care management is unknown. The aim of this study was to explore the experiences of those with undiagnosed cardiac symptoms living with an ICM. This study used a qualitative descriptive design. Analysis of data was by intraparticipant analysis, interparticipant analysis, and interrelationships. Three global categories emerged: (a) influences on self-care, (b) dealing and (c) monitoring. Self-care management after insertion of the ICM was determined by the participant's perception of health, what symptoms they were experiencing and whether there was a positive or negative experience with the clinician. Many indicated little to no regular communication regarding symptoms and ICM results. Increasing communication relevant to management of health and long-term findings may assist in enhancing physical and psychological health.

Exploring polypharmacy in elderly women after myocardial infarction.

The aims of the study were to: (a) examine the number, absolute volume, and type of daily medications older women were taking 6 to 12 months post-myocardial infarction (MI); (b) describe the financial burden of cardiac medications; and (c) examine the relationship of age, education, and income to the number of medications. An analysis of a cross-sectional descriptive study of women >or= 65 years of age who were post-MI was used. Most (89%; N = 83) were taking at least one cardiac medication, costs per day varied ($0.13-$6.75), and total number of pills taken per day was 1 to 19. Age, education, and income did not explain the number of medications. Consideration of the financial burden of medications is important to increase compliance and foster secondary prevention in older women.
