RESUMEN

BACKGROUND: Frailty is associated with poor outcomes among older adults with hypertension and complicates its pharmacological management. Here, we assessed whether 12-weeks of instructor-guided, group Tai Chi (TC) practice improved frailty relative to Healthy Aging Practice-centered Education (HAP-E) classes in older adults with hypertension. METHODS: Secondary analysis of a randomized controlled trial in San Diego County, USA, of 167 community-dwelling individuals aged ≥ 60 yrs (70% female; 72.1 ± 7.5 yrs), defined as non-frail (66%) or frail (34%) based on 53-item deficit accumulation frailty index (FI). Linear mixed-effects models were used to assess pre-to-post intervention differences in FI and logistic regression to explore differential odds of clinically meaningful FI change. RESULTS: One hundred thirty-one participants completed post-intervention assessments. Frailty decreased pre-to-post intervention in the TC (ΔFI = - 0.016, d = - 0.39, - 0.75 to - 0.03), but not the HAP-E arm (ΔFI = - 0.009, d = - 0.13, - 0.52-0.27), despite no significant group differences between the TC and HAP-E arms (d = - 0.11, - 0.46-0.23). Furthermore, greater odds of improved FI were observed for frail participants in the TC (OR = 3.84, 1.14-14.9), but not the HAP-E (OR = 1.34, 0.39-4.56) arm. Subgroup analysis indicated treatment effects in TC were attributed to frail participants (frail: ΔFI = - 0.035, d = - 0.68, -1.26 to - 0.08; non-frail: ΔFI = - 0.005, d = - 0.19, - 0.59-0.22), which was not the case in the HAP-E arm (frail: ΔFI = - 0.017, d = - 0.23, - 0.81-0.35; non-frail: ΔFI = - 0.003, d = - 0.07, - 0.47-0.33). Frail participants were no more likely to drop-out of the study than non-frail (71% vs. 69% retained). CONCLUSIONS: Twelve weeks of twice-weekly guided TC practice was well-tolerated, associated with decreases in frailty, and increased odds of clinically meaningful FI improvement at post-intervention.

RESUMEN

OBJECTIVE: To compare the effectiveness of 12 weeks of community-based, in-person, group Tai Chi (TC) and Health Education (HAP-E) in improving health and wellbeing in older adults with hypertension and in promoting psychological resilience during COVID-19. METHODS: A 12-week randomized controlled trial (RCT) in San Diego County, USA. Self-reported depressive symptoms, anxiety, sleep disturbances, gratitude, resilience, mental and physical health were assessed in-person pre- and post-intervention, and by long-term follow-up surveys during COVID-19. Linear mixed-effects models were used to assess study arm differences over time and logistic regression to identify predictors of positive intervention response. RESULTS: Of 182 randomized participants (72.6 ± 7.9 yrs; 72% female), 131 completed the intervention. Modest improvements in health and wellbeing occurred post-intervention in both arms (Cohen's d: TC = 0.38, 95% CI: 0.25-0.51; HAP-E = 0.24, 0.11-0.37), though positive intervention responses were more than twice as likely in TC (OR = 2.29, 1.07-4.57). Younger age, higher anxiety, and poorer mental health at baseline predicted greater odds of response. Small declines in health and wellbeing were reported at the first COVID-19 follow-up, with smaller declines in the TC arm (Cohen's d: TC = -0.15, -0.31-0.00; HAP-E = -0.34, -0.49 to -0.19). Health and wellbeing stabilized at the second COVID-19 follow-up. Most participants (>70%) reported that the interventions benefitted their health and wellbeing during COVID-19. CONCLUSION: TC and HAP-E improved health and wellbeing, though TC conferred greater odds of an improved mental health response. Declines in health and wellbeing were observed at pandemic follow-up, with smaller declines in the TC arm, suggesting increased resilience.

RESUMEN

OBJECTIVE: This study aimed to investigate the role of systemic inflammation in reduced cognitive functioning in patients with early-stage heart failure (HF) while determining associations with other cardiovascular risk factors. METHODS: Patients with stage B HF (n = 270; mean [standard deviation] age = 66.1 [10.1] years) were examined cross-sectionally for relationships among cardiovascular disease (CVD) and psychological risk factors, C-reactive protein (CRP), and Montreal Cognitive Assessment (MoCA) scores. A subsample (n = 83) at high risk for stage C HF (B-type natriuretic peptide levels ≥65 pg/ml) were followed up for 12 months for relationships between CRP levels and cognitive function. RESULTS: Baseline smoking (χ2 = 6.33), unmarried (χ2 = 12.0), hypertension (χ2 = 5.72), greater body mass index (d = 0.45), and physical fatigue (d = 0.25) were related to higher CRP levels (p values < .05). Cross-sectionally, CRP levels were negatively related to MoCA scores, beyond CVD (ΔR2 = 0.022, ß = -0.170, p < .010) and psychological risk factors (ΔR2 = 0.016, ß = 0.145, p < .027), and related to mild cognitive impairment criteria (odds ratio = 1.35, 95% confidence interval [CI] = 1.00-1.81, p = .046). Across 12 months, B-type natriuretic peptide high-risk patients with CRP levels ≥3 mg/L had lower MoCA scores (23.6; 95% CI = 22.4-24.8) than did patients with CRP levels <3 mg/L (25.4; 95% CI = 24.4-26.5; p = .024). CONCLUSIONS: Patients with stage B HF and heightened CRP levels had greater cognitive impairment at baseline and follow-up, independent of CVD and potentially psychological risk factors. Low-grade systemic inflammation may be one mechanism involved in cognitive dysfunction at early stages of HF.

RESUMEN

OBJECTIVES: Given the evidence of multi-parameter risk factors in shaping cognitive outcomes in aging, including sleep, inflammation, cardiometabolism, and mood disorders, multidimensional investigations of their impact on cognition are warranted. We sought to determine the extent to which self-reported sleep disturbances, metabolic syndrome (MetS) factors, cellular inflammation, depressive symptomatology, and diminished physical mobility were associated with cognitive impairment and poorer cognitive performance. DESIGN: This is a cross-sectional study. SETTING: Participants with elevated, well-controlled blood pressure were recruited from the local community for a Tai Chi and healthy-aging intervention study. PARTICIPANTS: One hundred forty-five older adults (72.7 ± 7.9 years old; 66% female), 54 (37%) with evidence of cognitive impairment (CI) based on Montreal Cognitive Assessment (MoCA) score ≤24, underwent medical, psychological, and mood assessments. MEASUREMENTS: CI and cognitive domain performance were assessed using the MoCA. Univariate correlations were computed to determine relationships between risk factors and cognitive outcomes. Bootstrapped logistic regression was used to determine significant predictors of CI risk and linear regression to explore cognitive domains affected by risk factors. RESULTS: The CI group were slower on the mobility task, satisfied more MetS criteria, and reported poorer sleep than normocognitive individuals (all p < 0.05). Multivariate logistic regression indicated that sleep disturbances, but no other risk factors, predicted increased risk of evidence of CI (OR = 2.00, 95% CI: 1.26-4.87, 99% CI: 1.08-7.48). Further examination of MoCA cognitive subdomains revealed that sleep disturbances predicted poorer executive function (ß = -0.26, 95% CI: -0.51 to -0.06, 99% CI: -0.61 to -0.02), with lesser effects on visuospatial performance (ß = -0.20, 95% CI: -0.35 to -0.02, 99% CI: -0.39 to 0.03), and memory (ß = -0.29, 95% CI: -0.66 to -0.01, 99% CI: -0.76 to 0.08). CONCLUSIONS: Our results indicate that the deleterious impact of self-reported sleep disturbances on cognitive performance was prominent over other risk factors and illustrate the importance of clinician evaluation of sleep in patients with or at risk of diminished cognitive performance. Future, longitudinal studies implementing a comprehensive neuropsychological battery and objective sleep measurement are warranted to further explore these associations.

RESUMEN

OBJECTIVE: Cognitive deficits are common in patients with heart failure (HF), and can negatively affect self-care, predict rehospitalizations, and increase mortality rates 5-fold. Inflammation can produce vascular pathology, reducing cerebral blood flow to brain regions necessary for optimal cognitive function. The purpose of the investigation was to identify a pattern of peripheral blood inflammation-related biomarkers associated with cognitive impairment in patients with HF. METHODS: Forty-five outpatients (median age = 67 years, SD = 9.9) were recruited from University of California, San Diego (UCSD) and Veterans Affairs San Diego Healthcare Systems (VASDHS), diagnosed with New York Heart Association Stages I-III HF. Participants were administered the Montreal Cognitive Assessment (MoCA) as a measure of global cognitive impairment, and blood was analyzed for plasma biomarkers, interferon-γ, tumor necrosis factor-α (TNFα), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), brain-derived neurotrophic factor (BDNF), interleukin-8 (IL-8), matrix metallopeptidase-9 (MMP-9), IL-6, C-reactive protein (CRP), and serum amyloid-A (SAA). RESULTS: Almost half the patients scored below the threshold on the MoCA, indicating at least mild cognitive impairment. A factor analysis produced three biomarker factors: vascular inflammatory factor-1: TNFα, sICAM1, sVCAM1; neuroinflammatory factor-2: BDNF, MMP-9, IL-8; peripheral inflammatory factor-3: IL-6, CRP, SAA. Only vascular inflammatory factor-1 was significantly associated with cognitive function (MoCA) (ΔR2 = 0.214, beta = -0.468, p = 0.008). CONCLUSIONS: In this cohort with HF, vascular inflammation appears related to poorer cognitive function. This could indicate targets for treatment to reduce cognitive deficits in HF. However, this is a preliminary study, and further research is needed.

RESUMEN

OBJECTIVE: Stage B, asymptomatic heart failure (HF) presents a therapeutic window for attenuating disease progression and development of HF symptoms, and improving quality of life. Gratitude, the practice of appreciating positive life features, is highly related to quality of life, leading to development of promising clinical interventions. However, few gratitude studies have investigated objective measures of physical health; most relied on self-report measures. We conducted a pilot study in Stage B HF patients to examine whether gratitude journaling improved biomarkers related to HF prognosis. METHODS: Patients (n = 70; mean [standard deviation] age = 66.2 [7.6] years) were randomized to an 8-week gratitude journaling intervention or treatment as usual. Baseline (T1) assessments included the six-item Gratitude Questionnaire, resting heart rate variability (HRV), and an inflammatory biomarker index. At T2 (midintervention), the six-item Gratitude Questionnaire was measured. At T3 (postintervention), T1 measures were repeated but also included a gratitude journaling task. RESULTS: The gratitude intervention was associated with improved trait gratitude scores (F = 6.0, p = .017, η = 0.10), reduced inflammatory biomarker index score over time (F = 9.7, p = .004, η = 0.21), and increased parasympathetic HRV responses during the gratitude journaling task (F = 4.2, p = .036, η = 0.15), compared with treatment as usual. However, there were no resting preintervention to postintervention group differences in HRV (p values > .10). CONCLUSIONS: Gratitude journaling may improve biomarkers related to HF morbidity, such as reduced inflammation; large-scale studies with active control conditions are needed to confirm these findings. TRIAL REGISTRATION: Clinicaltrials.govidentifier:NCT01615094.

RESUMEN

Mindfulness based interventions have been associated with improvements in physical health; however, the mechanisms underlying these changes are unclear. The current study explored relationships between trait mindfulness, blood pressure (BP) and interleukin-6 (IL-6). Relationships between physical health variables and (1) a composite score of mindfulness, (2) individual facets of mindfulness and (3) interactions between theoretically relevant pairs of mindfulness subscales were investigated. One hundred and thirty healthy, young adults [M (SD) age = 21.7(2.7) years] reported trait levels of mindfulness (Five Facet Mindfulness Questionnaire, subscales include: observing, describing, acting with awareness (AWA), nonjudging and nonreactivity), had their resting BP measured and underwent a blood draw to assesses circulating IL-6 levels. Age, gender, body mass index, race/ethnicity, depression and perceived stress were obtained and used as covariates. A composite score of trait mindfulness was associated with lower BP and a trend suggested that it was also associated with lower IL-6. Investigation of individual facets of mindfulness revealed interactions between the subscales AWA and nonjudging, such that higher endorsement of AWA was associated with lower BP only when nonjudging was also high. A second interaction was observed between the subscales observing and nonreactivity, such that higher endorsement of observing was associated with lower IL-6 only when levels of nonreactivity were also high. Trait mindfulness was associated with both BP and IL-6. Examining interactions between facets of mindfulness variables may be important in understanding how mindfulness based interventions influence physiology.

RESUMEN

Depression adversely predicts prognosis in individuals with symptomatic heart failure. In some clinical populations, spiritual wellness is considered to be a protective factor against depressive symptoms. This study examined associations among depressive symptoms, spiritual wellbeing, sleep, fatigue, functional capacity, and inflammatory biomarkers in 132 men and women with asymptomatic stage B heart failure (age 66.5 years ± 10.5). Approximately 32 % of the patients scored ≥10 on the Beck Depression Inventory, indicating potentially clinically relevant depressive symptoms. Multiple regression analysis predicting fewer depressive symptoms included the following significant variables: a lower inflammatory score comprised of disease-relevant biomarkers (p < 0.02), less fatigue (p < 0.001), better sleep (p < 0.04), and more spiritual wellbeing (p < 0.01) (overall model F = 26.6, p < 0.001, adjusted R square = 0.629). Further analyses indicated that the meaning (p < 0.01) and peace (p < 0.01) subscales, but not the faith (p = 0.332) subscale, of spiritual wellbeing were independently associated with fewer depressive symptoms. Interventions aimed at increasing spiritual wellbeing in patients lives, and specifically meaning and peace, may be a potential treatment target for depressive symptoms asymptomatic heart failure.

RESUMEN

COVID-19 pandemic-related traumatic stress (PRTS) symptoms are reported in various populations, but risk factors in older adults with chronic medical conditions, remain understudied. We therefore examined correlates and pre-pandemic predictors of PRTS in older adults with hypertension during COVID-19. Participants in California, aged 61-92 years (n = 95), participated in a pre-pandemic healthy aging trial and later completed a COVID-19 assessment (May to September 2020). Those experiencing ⩾1 PRTS symptom (n = 40), and those without PRTS symptoms (n = 55), were compared. The PRTS+ group had poorer mental and general health and greater impairment in instrumental activities of daily living. Pre-pandemic biomarkers of vascular inflammation did not predict increased odds of PRTS; however, greater pre-pandemic anxiety and female gender did predict PRTS during COVID-19. Our findings highlight PRTS as a threat to healthy aging in older adults with hypertension; targeted approaches are needed to mitigate this burden, particularly for females and those with pre-existing anxiety.

RESUMEN

In the current study, the antioxidant and anti-inflammatory potential of hydroethanolic extract of T. foenum-graecum seeds was evaluated. Phenolic profiling of T. foenum-graecum was conducted through high-performance liquid chromatography-photodiode array (HPLC-PDA) as well as through the mass spectrometry technique to characterize compounds responsible for bioactivity, which confirmed almost 18 compounds, 13 of which were quantified through a chromatographic assay. In vitro antioxidant analysis of the extract exhibited substantial antioxidant activities with the lowest IC50 value of both DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid) inhibition assays. The extract was found to be non-toxic against human RBCs and murine macrophage RAW 264.7 cells. Moreover, the extract significantly (p < 0.001) reduced the lipopolysaccharide (LPS)-induced tumor necrosis factor alpha (TNF-α), intrlukin-6 (IL-6), prostaglandin E2 (PGE2), and nitric oxide (NO) in RAW 264.7 cells in a concentration-dependent manner. The hydroethanolic extract of T. foenum-graecum exhibited considerable anti-inflammatory potential by decreasing the cellular infiltration to the inflammatory site in both carrageenan-induced peritonitis and an air pouch model of inflammation. Pretreatment with T. foenum-graecum extract caused significant improvement in antioxidants such as superoxide dismutase (SOD), CAT (catalase), malondialdehyde (MDA), and myeloperoxidase (MPO) against oxidative stress induced by carrageenan. Based on our results of in vivo and in vitro experimentation, we concluded that hydroethanolic extract of T. foenum-graecum is a potential source of phenolic compounds with antioxidant and anti-inflammatory potential.

RESUMEN

Recently, there has been a growth of interest in factors that play a protective role in sleep. This study is an exploratory analysis investigating relations between daily hassles and uplifts (events appraised as pleasant) and measures of subjective and polysomnography (PSG)-assessed sleep in a group of healthy adults (N = 135). Hassles and uplifts were assessed with the Combined Hassles and Uplifts Scale (CHUS), subjective sleep was assessed with the Pittsburgh Sleep Quality Index (PSQI), and objective sleep was assessed with standard PSG. After controlling for covariates, uplifts intensity was associated with subjective sleep and PSG-assessed sleep. Specifically, increased uplifts intensity was associated with better subjective sleep, decreased time slept in Stage 2 sleep, and increased time slept in slow wave sleep (SWS). One's perception of the magnitude of positive events may play a role in sleep and should be examined in future investigations.

RESUMEN

OBJECTIVES: To test the hypothesis that a nocturnal decrease of secretion of inflammation markers and catecholamines would be associated with mood and stress variables even after controlling for objective sleep variables. METHODS: A total of 130 healthy volunteers participated in this study, spending 2 nights in the Gillin Laboratory of Sleep and Chronobiology at the University of California, San Diego, General Clinical Research Center. Blood samples were obtained before sleep (10:30 PM) and after awakening (6:30 AM) on the first day, and these samples were assayed for inflammatory biomarkers and catecholamines. On the second night, polysomnographic records were scored for objective sleep variables, e.g., total sleep time and wake after sleep onset. Self-rating scales for mood, stress, depression, and daily hassles were administered the second day. RESULTS: The nocturnal decrease in interleukin-6 was smaller in people who reported more negative mood or fatigue and greater in those who reported more uplift events (e.g., with Profile of Mood States fatigue r(p) = -.25 to -.30). People with high stress or high depression levels had smaller nocturnal decreases of epinephrine. That relationship was even stronger when partial correlations were used to control for morning level and sleep variables. The associations between nocturnal changes of C-reactive protein, soluble tumor necrosis factor-receptor I, and norepinephrine with psychological states were nonremarkable. CONCLUSIONS: The analyses of nocturnal change scores (difference scores) add substantial information compared with the traditional analyses of morning levels of immune variables and catecholamines alone. Subjective well-being is significantly associated with a greater nocturnal decrease of interleukin-6 and epinephrine. More research on nocturnal adaptation processes is warranted.

RESUMEN

OBJECTIVE: Almost half of patients with heart failure (HF) have cognitive impairment. While exercise relates to better cognitive health, a hallmark of HF is exercise intolerance. The study objective was to explore whether light-to-moderate exercise improves cognitive function in patients with HF. METHODS: This was an exploratory parallel design study of 69 patients with symptomatic HF (mean age = 65, SD = 10), recruited from VA and University of California, San Diego Healthcare Systems. Participants were randomized to Tai Chi (TC) (n = 24), resistance band (RB) exercise (n = 22) or treatment as usual (TAU) (n = 23). The primary outcome was change in Montreal Cognitive Assessment (MoCA) scores. We further explored if changes in Beck Depression Inventory - IA (BDI-IA) scores or inflammation biomarkers, CRP, TNFα and IL-6 related to altered cognitive function. RESULTS: There was a fixed effect of group for MoCA scores changes (F = 8.07, p = .001). TC and RB groups had greater MoCA score increases versus TAU, but no differences were found between TC and RB. Depression symptom changes predicted altered MoCA scores (ΔR2 = 0.15, Β = -0.413, p = .001). However, group did not interact with depression symptom levels for MoCA alterations (p = .392). Changes in CRP levels predicted MoCA scores (ΔR2 = 0.078, Β = -0.283, p = .01), but group did not interact with CRP levels for MoCA alterations (p = .689). CONCLUSIONS: Light-to-moderate exercises, TC and RB may improve cognitive function. However, the mechanisms remain unclear. ClinicalTrials.gov: NCT01625819.

RESUMEN

In the United States, heart failure (HF) affects approximately 6.5 million adults. While studies show that individuals with HF often suffer from adverse symptoms such as depression and anxiety, studies also show that these symptoms can be at least partially offset by the presence of spiritual wellbeing. In a sample of 327 men and women with AHA/ACC classification Stage B HF, we found that more spirituality in patients was associated with better clinically-related symptoms such as depressed mood and anxiety, emotional variables (affect, anger), well-being (optimism, satisfaction with life), and physical health-related outcomes (fatigue, sleep quality). These patients also showed better self-efficacy to maintain cardiac function. Simply belonging to a religious organization independent of spiritualty, however, was not a reliable predictor of health-related benefits. In fact, we observed instances of belonging to a religious organization unaccompanied by parallel spiritual ratings, which appeared counterproductive.

RESUMEN

Although the impact of medicinal and culinary herbs on health and disease has been studied to varying extents, scarcely little is known about the impact of these herbs on gut microbiota and how such effects might contribute to their health benefits. We applied in vitro anaerobic cultivation of human fecal microbiota followed by 16S rRNA sequencing to study the modulatory effects of 4 culinary spices: Curcuma longa (turmeric), Zingiber officinale (ginger), Piper longum (pipli or long pepper), and Piper nigrum (black pepper). All herbs analyzed possessed substantial power to modulate fecal bacterial communities to include potential prebiotic and beneficial repressive effects. We additionally analyzed the sugar composition of each herb by mass spectrometry and conducted genome reconstruction of 11 relevant sugar utilization pathways, glycosyl hydrolase gene representation, and both butyrate and propionate biosynthesis potential to facilitate our ability to functionally interpret microbiota profiles. Results indicated that sugar composition is not predictive of the taxa responding to each herb; however, glycosyl hydrolase gene representation is strongly modulated by each herb, suggesting that polysaccharide substrates present in herbs provide selective potential on gut communities. Additionally, we conclude that catabolism of herbs by gut communities primarily involves sugar fermentation at the expense of amino acid metabolism. Among the herbs analyzed, only turmeric induced changes in community composition that are predicted to increase butyrate-producing taxa. Our data suggests that substrates present in culinary spices may drive beneficial alterations in gut communities thereby altering their collective metabolism to contribute to the salubrious effects on digestive efficiency and health. These results support the potential value of further investigations in human subjects to delineate whether the metabolism of these herbs contributes to documented and yet to be discovered health benefits.

RESUMEN

PURPOSE: To compare 2 mild-to-moderate group exercises and treatment as usual (TAU) for improvements in physical function and depressive symptoms. METHODS: Patients with heart failure (n = 70, mean age = 66 yr, range = 45-89 yr) were randomized to 16 wk of tai chi (TC), resistance band (RB) exercise, or TAU. RESULTS: Physical function differed by group from baseline to follow-up, measured by distance walked in the 6-min walk test (F = 3.19, P = .03). Tai chi participants demonstrated a nonsignificant decrease of 162 ft (95% confidence interval [CI], 21 to -345, P = .08) while distance walked by RB participants remained stable with a nonsignificant increase of 70 ft (95% CI, 267 to -127, P = .48). Treatment as usual group significantly decreased by 205 ft (95% CI, -35 to -374, P = .02) and no group differences occurred over time in end-systolic volume (P = .43) and left ventricular function (LVEF) (P = .67). However, groups differed over time in the Beck Depression Inventory (F = 9.2, P < .01). Both TC and RB groups improved (decreased) by 3.5 points (95% CI, 2-5, P < .01). Treatment as usual group decreased insignificantly 1 point (95% CI, -1 to 3, P = .27). CONCLUSIONS: Tai chi and RB participants avoided a decrease in physical function decrements as seen with TAU. No groups changed in cardiac function. Both TC and RB groups saw reduced depression symptoms compared with TAU. Thus, both TC and RB groups avoided a decrease in physical function and improved their psychological function when compared with TAU.

RESUMEN

BACKGROUND: According to Ayurveda, the traditional medical system of India, doshas are a combination of characteristics based on a five-element philosophy that drive our mental and physical tendencies. When the doshas, or functional principles, are out of balance in quality or quantity, wellbeing is adversely affected and symptoms manifest. OBJECTIVE: This study examined relationships among imbalances in the doshas (termed Vikruti) reported via questionnaire and Western measures of psychological states. MATERIALS AND METHODS: Study participants were 101 women (n = 81) and men (n = 20), mean age 53.9 years (SD = 11.7; range 32-80). Participants completed questionnaires to categorize their Vikruti type and psychological states, which included depressed mood (CESD), anxiety (PROMIS), rumination & reflection (RRQ), mindfulness (MAAS), stress (PSS), and quality of life (Ryff). RESULTS: Multivariate general linear modeling, controlling for age, gender and body mass index (BMI), showed that Vata imbalance was associated with more anxiety (p ≤ 0.05), more rumination (p ≤ 0.01), less mindfulness (p ≤ 0.05), and lower overall quality of life (p ≤ 0.01). Pitta imbalance was associated with poorer mood (p ≤ 0.01) and less mindfulness (p ≤ 0.05), more anxiety (p ≤ 0.05) and stress (p ≤ 0.05). Kapha imbalance was associated with more stress (p ≤ 0.05), more rumination (p ≤ 0.05) and less reflection (p ≤ 0.05). CONCLUSION: These findings suggest that symptoms of mind-body imbalances in Ayurveda are differentially associated with western assessments of psychological states. Ayurvedic dosha assessment may be an effective way to assess physical as well as emotional wellbeing in research and clinical settings.

RESUMEN

BACKGROUND: The presence of concomitant Type II diabetic mellitus (T2DM) and depressive symptoms adversely affects individuals with symptomatic heart failure (HF). HYPOTHESIS: In presymptomatic stage B HF, this study hypothesized the presence of greater inflammation and depressive symptoms in T2DM as compared to non-T2DM Stage B patients. METHODS: This cross-sectional study examined clinical parameters, inflammatory biomarkers, and depressive symptoms in 349 T2DM and non-T2DM men with asymptomatic stage B HF (mean age 66.4 years ±10.1; range 30-91). RESULTS: Fewer diabetic HF patients had left ventricular (LV) systolic dysfunction (P < .05) although more had LV diastolic dysfunction (P < .001). A higher percentage of T2DM HF patients were taking ACE-inhibitors, beta-blockers, calcium channel blockers, statins, and diuretics (P values < .05). T2DM HF patients had higher circulating levels of interleukin-6 (IL-6) (P < .01), tumor necrosis factor-alpha (P < .01), and soluble ST2 (sST2) (P < .01) and reported more somatic/affective depressive symptoms (Beck Depression Inventory II) (P < .05) but not cognitive/affective depressive symptoms (P = .20). Among all patients, in a multiple regression analysis predicting presence of somatic/affective depressive symptoms, sST2 (P = .026), IL-6 (P = .010), B-type natriuretic peptide (P = .016), and sleep (Pittsburgh Sleep Quality Index [P < .001]) were significant predictors (overall model F = 15.39, P < .001, adjusted R2 = .207). CONCLUSIONS: Somatic/affective but not cognitive/affective depressive symptoms are elevated in asymptomatic HF patients with T2DM patients. Linkages with elevated inflammatory and cardiac relevant biomarkers suggest shared pathophysiological mechanisms among T2DM HF patients with somatic depression, and these conditions are responsive to routine interventions, including behavioral.

RESUMEN

OBJECTIVE: This study examined the effects of a comprehensive mind-body program on sense of nondual awareness and spiritual awakening. DESIGN AND INTERVENTION: The study compared the effects of participation in an intensive 6-day Ayurveda-based mind-body program that addressed physical, emotional, and spiritual domains as compared with a control condition. SETTING: Resort setting. SUBJECTS: Participants were 69 healthy women and men (mean age 53.9 years; range 32-86). OUTCOME MEASURE: The primary outcome was the Nondual Embodiment Thematic Inventory (NETI). RESULTS: A significant group by time interaction (p = 0.029) indicated that after the intervention, participants in the mind-body program showed a significant increase in NETI scores (p < 0.03), which was sustained 1 month later (p < 0.01). CONCLUSION: Findings suggest that an intensive program providing holistic instruction and experience in mind-body practices can lead to a significant and sustained shift in perception of self-awareness, one that is likely favorable to well-being.

RESUMEN

BACKGROUND: Physical fitness may attenuate the increased atherosclerotic risk in patients with systemic hypertension. We investigated the association of screening blood pressure (BP) and cardiorespiratory fitness with baseline levels and exercise-induced changes in levels of soluble atherosclerotic risk markers. METHODS: Twenty-six otherwise healthy and unmedicated subjects with elevated BP (systolic BP and/or diastolic BP > or =130/85 mm Hg) and 40 subjects with normal BP underwent 20-min treadmill exercise at 65% to 70% of predetermined peak oxygen consumption (VO(2peak)). Interleukin (IL)-6, soluble intercellular adhesion molecule (sICAM)-1, von Willebrand factor (VWF) antigen, and plasminogen activator inhibitor (PAI)-1 antigen were measured at baseline (ie, pre-exercise), early postexercise, and late postexercise (ie, 25 min after exercise). RESULTS: At baseline, higher screening mean arterial BP (MAP) independently predicted higher sICAM-1 levels (P = .031), and lower VO(2peak) independently predicted higher IL-6 (P = .016) and PAI-1 (P < .001) levels. Early and late postexercise lower VO(2peak) was associated with higher mean PAI-1 (P < or = .072) and IL-6 (P < or = .026) levels, and higher screening MAP was associated with higher mean sICAM-1 levels (P < or = .035). Higher VO(2peak) was associated with a greater PAI-1 increase from baseline to early postexercise in subjects with elevated BP (P = .045) but not in those with normal BP. CONCLUSIONS: Circulating levels of some atherosclerotic risk markers at baseline and with exercise were higher with elevated BP and lower with better fitness. Greater fitness did not particularly protect subjects with elevated BP from potentially harmful responses of atherosclerotic risk markers to acute physical exercise.
