Abstract
Instant and strong adhesion to underwater adherends is a big challenge due to the continuous interference of water. Mussel foot protein-bioinspired catechol-based adhesives have garnered great interest in addressing this issue. Herein, a novel self-made catecholic compound with a long aliphatic chain was utilized to prepare thin (∼0.07 mm) and optically transparent (>80%) wet/underwater adhesive tapes by UV-initiated polymerization. Its adhesion activity was water-triggered, fast (<1 min), and strong (adhesion strength to porcine skin: ∼1.99 MPa; interfacial toughness: ∼610 J/m2, burst pressure: ∼1950 mmHg). The effect of the catechol/phenol group and positively charged moiety on the wet/underwater adhesion to abiotic/biotic substrates was investigated. On the wet/underwater adherends, the tape with catechol groups presented much higher interfacial toughness, adhesion strength, and burst pressure than the analogous tape with phenol groups. The tape with both the catechol group and cationic polyelectrolyte chitosan had a more impressive improvement in its adhesion to wet/underwater biological tissues than to abiotic substrates. Therefore, catechol and a positive moiety in the tape would synergistically enhance its wet/underwater adhesion to various substrates, especially to biological tissues. The instant, strong, and noncytotoxic tape may provide applications in underwater adhesion for sealing and wound closure.

Abstract
PURPOSE With arterial hypertension as a global risk factor for cerebrovascular and cardiovascular diseases, we examined whether retinal blood vessel caliber and tortuosity assessed by a vessel-constraint network model can predict the incidence of hypertension. METHODS The community-based prospective study included 9230 individuals who were followed for 5 years. Ocular fundus photographs taken at baseline were analyzed by a vessel-constraint network model. RESULTS Within the 5-year follow-up, 1279 (18.8%) and 474 (7.0%) participants out of 6813 individuals free of hypertension at baseline developed hypertension and severe hypertension, respectively. In multivariable analysis, a higher incidence of hypertension was related to a narrower retinal arteriolar diameter ( P < 0.001), wider venular diameter ( P = 0.005), and a smaller arteriole-to-venule diameter ratio ( P < 0.001) at baseline. Individuals with the 5% narrowest arteriole or the 5% widest venule diameter had a 17.1-fold [95% confidence interval (CI):7.9, 37.2] or 2.3-fold (95% CI: 1.4, 3.7) increased risk for developing hypertension, as compared with those with the 5% widest arteriole or the 5% narrowest venule. The area under the receiver operator characteristic curve for predicting the 5-year incidence of hypertension and severe hypertension was 0.791 (95% CI: 0.778, 0.804) and 0.839 (95% CI: 0.821, 0.856), respectively. Although the venular tortuosity was positively associated with the presence of hypertension at baseline ( P = 0.01), neither arteriolar tortuosity nor venular tortuosity was associated with incident hypertension (both P ≥ 0.10). CONCLUSION AND RELEVANCE Narrower retinal arterioles and wider venules indicate an increased risk for incident hypertension within 5 years, while tortuous retinal venules are associated with the presence rather than the incidence of hypertension. The automatic assessment of retinal vessel features performed well in identifying individuals at risk of developing hypertension.

Abstract
Hypertension is a risk factor for cardiovascular disease. Black women have high
rates of hypertension compared to women of other racial or ethnic groups and are
disproportionately affected by psychosocial stressors such as racial
discrimination, gender discrimination, and caregiving stress. Evidence suggests
that stress is associated with incident hypertension and hypertension risk.
Stress management is associated with improvements improved blood pressure
outcomes. The purpose of this review is to synthesize evidence on effects of
stress management interventions on blood pressure in Black women. A
comprehensive search of scientific databases was conducted. Inclusion criteria
included studies that were: (1) primary research that tested an intervention;
(2) in the English language; (3) included African-American women; (4)
incorporated stress in the intervention; (5) included blood pressure as an
outcome; and (6) were US based. Eighteen studies met inclusion criteria. Ten
(56%) studies tested meditation-based interventions, two (11%) tested coping and
affirmation interventions, and six (33%) tested lifestyle modification
interventions that included stress management content. Thirteen of the studies
were randomized controlled trials. Reductions in blood pressure were observed in
all of the meditation-based interventions, although the magnitude and
statistical significance varied. Comprehensive lifestyle interventions were also
efficacious for reducing blood pressure, although the relative contribution of
stress management versus behavior modification could not be evaluated. Coping
and affirmation interventions did not affect blood pressure. Most of the
reviewed studies included small numbers of Black women and did not stratify
results by race and gender, so effects remain unclear. This review highlights
the urgent need for studies specifically focusing on Black women. Given the
extensive disparities in cardiovascular disease morbidity and mortality, whether
stress management can lower blood pressure and improve primary and secondary
cardiovascular disease prevention among Black women is an important question for
future research.

Abstract
New recommendations for hypertension (HTN) diagnosis and treatment highlight the role of self-care activities in managing blood pressure (BP). This cross-sectional study investigated the predictive validity of the Hypertension Self-Care Activity Level Effects (H-SCALE) measure and examined the relative and cumulative effects of HTN self-care adherence on BP. We pooled baseline data from three studies ( N = 79), resulting in a gender and racially balanced sample. Partial correlations determined the relative effects of individual self-care behaviors on BP. We modeled the relationship between adherence to self-care behaviors and BP control using logistic regression. Physical activity had the greatest correlation with systolic BP. Adherence to each additional self-care behavior increased the odds of systolic BP control by 88% (95% confidence interval (CI) = [1.20, 2.96]) and diastolic BP control by 74% (95% CI = [1.10, 2.75]). Results provide further evidence that the H-SCALE is a valid assessment tool and should be adopted by clinicians to aid in improving BP management.

Abstract
We have developed, tested, and successfully implemented an affordable, evidence-based, technology-enabled, data-driven, outcomes-oriented, comprehensive lifestyle health coaching (LHC) program. The LHC program has been used primarily to provide services to employees of larger employers (ie, with at least 3000 employees) but has also been implemented in a variety of other settings, including hospitals, cardiac rehabilitation centers, physician practices, and as part of multicenter clinical trials. The program is delivered mainly using the telephone and Internet. Health coaches are guided by a Web-based participant management and tracking system. Lifestyle management interventions are based on several behavior change models and strategies, especially adult learning theory, social learning theory, the stages of change model, single concept learning theory, and motivational interviewing. The program is administered by nonphysician health professionals whose services are integrated with the care provided by participants' physicians. Outcomes data from published studies, including randomized clinical trials and independent third-party conducted research, have documented the clinical effectiveness of this evidence-based approach in terms of modification of multiple risk factors in healthy persons as well as those with certain common chronic diseases.

Abstract
Although cell phone use and Internet access via cell phone is not marked by racial disparities, little is known about how cell phone use relates to blood pressure and health information seeking behaviors. The purposes of this study were to (a) describe Internet activities, cell phone use, and information seeking; (b) determine differences in blood pressure and information seeking between cell phone information seekers and nonseekers; and (c) examine cell phone information seeking as a predictor of blood pressure in African American women. Participants ( N = 147) completed a survey and had their blood pressure measured. Independent-sample t tests showed a significant difference in systolic blood pressure in cell phone information seekers and nonseekers. Linear regression revealed cell phone information seeking as an independent predictor of systolic blood pressure, despite confounders. It is possible that cell phone information seekers were using health information to make decisions about self-management of blood pressure.

Abstract
BACKGROUND AND OBJECTIVE Evidence suggests that dance therapy may have positive effects in areas such as cardiovascular parameters and sleep. The aim of the present study is to explore whether a dance therapy programme improves sleep and blood pressure in a population of middle-aged pre-hypertensive and hypertensive women. METHODS A randomised controlled trial was conducted, in which participants were assigned to one of 2 groups: standard care (with usual activities and medication) or dance therapy (in which the participants followed a dance therapy programme, in addition to their medication). The intervention was an 8-week, 3-times-per-week, progressive and specific group dance-training programme. The dance steps were specifically designed to improve balance by shifting the body and relocating the centre of gravity. The main measures obtained were blood pressure, sleep quality and quality of life, measured by the Pittsburgh Sleep Quality Index and the European Quality of Life Questionnaire. RESULTS Sixty-seven pre-hypertensive and hypertensive middle-aged women were randomised to either an intervention group (n=35) or a control group (n=32) after baseline testing. The intervention group reported a significant improvement in blood pressure values (P<.01), as well as in sleep quality (P<.05) and quality of life (P<.001), compared to the control group. CONCLUSION The dance therapy programme improved blood pressure, sleep and quality of life in pre-hypertensive and hypertensive middle-aged women, and constitutes an interesting basis for larger-scale research.

Abstract
BACKGROUND Lifestyle modification is recommended for management of prehypertension, yet finding effective interventions to reach rural women is a public health challenge. This community-based clinical trial compared the effectiveness of standard advice to two multi-component theory-based tailored interventions, using web-based or print-mailed delivery, in reducing blood pressure among rural women, ages 40-69, with prehypertension. METHODS 289 women with prehypertension enrolled in the Wellness for Women: DASHing towards Health trial, a 12-month intervention with 12-month follow-up. Women were randomly assigned to groups using a 1:2:2 ratio, comparing standard advice (30-minute counseling session) to two interventions (two 2-hour counseling sessions, 5 phone goal-setting sessions, strength-training video, and 16 tailored newsletters, web-based or print-mailed). Linear mixed model methods were used to test planned pairwise comparisons of marginal mean change in blood pressure, healthy eating and activity, adjusted for age and baseline level. General estimating equations were used to examine the proportion of women achieving normotensive status and meeting health outcome criteria for eating and activity. RESULTS Mean blood pressure reduction ranged from 3.8 (SD = 9.8) mm Hg to 8.1 (SD = 10.4) mm Hg. The 24-month estimated marginal proportions of women achieving normotensive status were 47% for web-based, and 39% for both print-mailed and standard advice groups, with no group differences (p = .11 and p = .09, respectively). Web-based and print-mailed groups improved more than standard advice group for waist circumference (p = .017 and p = .016, respectively); % daily calories from fat (p = .018 and p = .030) and saturated fat (p = .049 and p = .013); daily servings of fruit and vegetables (p = .008 and p < .005); and low fat dairy (p < .001 and p = .002). Greater improvements were observed in web-based versus standard advice groups in systolic blood pressure (p = .048) and estimated VO2max (p = .037). Dropout rates were 6% by 6-months, 11.4% by 24 months, with no differences across groups. CONCLUSIONS Rural women with prehypertension receiving distance-delivery theory-based lifestyle modifications can achieve a reduction of blood pressure and attainment of normotensive status.

Abstract
The aim of this investigation was to determine and compare current and projected expenditure associated with chronic kidney disease (CKD), renal replacement therapy (RRT), and cardiovascular disease (CVD) in Australia. Data published by Australia and New Zealand Dialysis and Transplant Registry, Australian Institute of Health and Welfare, and World Bank were used to compare CKD-, RRT-, and CVD-related expenditure and prevalence rates. Prevalence and expenditure predictions were made using a linear regression model. Direct statistical comparisons of rates of annual increase utilised indicator variables in combined regressions. Statistical significance was set at P < 0.05. Dollar amounts were adjusted for inflation prior to analysis. Between 2012 and 2020, prevalence, per-patient expenditure, and total disease expenditure associated with CKD and RRT are estimated to increase significantly more rapidly than CVD. RRT prevalence is estimated to increase by 29%, compared to 7% in CVD. Average annual RRT per-patient expenditure is estimated to increase by 16%, compared to 8% in CVD. Total CKD- and RRT-related expenditure had been estimated to increase by 37%, compared to 14% in CVD. Per-patient, CKD produces a considerably greater financial impact on Australia's healthcare system, compared to CVD. Research focusing on novel preventative/therapeutic interventions is warranted.

Abstract
This study describes the relative influence of facial skin color, lifetime exposure to racial discrimination, chronic stress, and traditional prehypertension risk factors (family history of hypertension and age) on resting blood pressure and body mass index (BMI) among 196 southern African American (AA) female undergraduate students. Stepwise regression analyses indicated that skin color was the strongest predictor of systolic blood pressure (SBP), diastolic blood pressure (DBP), and BMI. Skin color, chronic stress, and family history of hypertension predicted 53% of the SBP variance. Skin color, chronic stress, and family history of hypertension predicted 30.2% of the DBP variance. Racism and age were not significant predictors of SBP or DBP. Of the variance in BMI, 33% was predicted by skin color, chronic stress, and racism. Age and family history of hypertension were not predictors of BMI. The current study provides evidence of the relationship of skin color and chronic stress to blood pressure among young southern AA women. The study identifies an important relationship between increased racial stress exposure and heavier BMIs, a predictor of prehypertensive risk.

Abstract
This study establishes preliminary validation of a measure that assesses hypertension self-care activities with clinical blood pressure (BP). The Hypertension Self-Care Activity Level Effects (H-SCALE) was administered to patients with hypertension to assess levels of self-care. Patients (n=154) were predominantly female (68.6%) and black (79.2%). Greater adherence to self-care was associated with lower systolic and diastolic BP for 5 of the 6 self-care behaviors. Medication adherence was correlated with systolic BP (r=-0.19, P<.05) and weight management adherence was correlated with diastolic BP (r=-0.22, P<.05) after controlling for other covariates. Increased adherence to recommended dietary practices was strongly correlated with higher systolic (r=0.29, P<.05) and diastolic BP (r=0.32, P<.05). The H-SCALE was acceptable for use in clinical settings, and adherence to self-care was generally aligned with lower BP. Assessment of hypertension self-care is important when working with individuals to control their BP.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a worldwide public health problem. In the National Kidney Foundation Disease Outcomes Quality Initiative guidelines it is stressed that lifestyle issues such as physical activity should be seen as cornerstones of the therapy. The physical fitness in adults with CKD is so reduced that it impinges on ability and capacity to perform activities in everyday life and occupational tasks. An increasing number of studies have been published regarding health effects of various regular exercise programmes in adults with CKD and in renal transplant patients. OBJECTIVES We aimed to: 1) assess the effects of regular exercise in adults with CKD and kidney transplant patients; and 2) determine how the exercise programme should be designed (e.g. type, duration, intensity, frequency of exercise) to be able to affect physical fitness and functioning, level of physical activity, cardiovascular dimensions, nutrition, lipids, glucose metabolism, systemic inflammation, muscle morphology and morphometrics, dropout rates, compliance, adverse events and mortality. SEARCH STRATEGY We searched the Cochrane Renal Group's specialised register, CENTRAL, MEDLINE, EMBASE, CINAHL, Web of Science, Biosis, Pedro, Amed, AgeLine, PsycINFO and KoreaMed. We also handsearched reference lists of review articles and included studies, conference proceeding's abstracts. There were no language restrictions.Date of last search: May 2010. SELECTION CRITERIA We included any randomised controlled trial (RCT) enrolling adults with CKD or kidney transplant recipients undergoing any type of physical exercise intervention undertaken for eight weeks or more. Studies using less than eight weeks exercise, those only recommending an increase in physical activity, and studies in which co-interventions are not applied or given to both groups were excluded. DATA COLLECTION AND ANALYSIS Data extraction and assessment of study and data quality were performed independently by the two authors. Continuous outcome data are presented as standardised mean difference (SMD) or mean difference (MD) with 95% confidence intervals (CI). MAIN RESULTS Forty-five studies, randomising 1863 participants were included in this review. Thirty two studies presented data that could be meta-analysed. Types of exercise training included cardiovascular training, mixed cardiovascular and resistance training, resistance-only training and yoga. Some studies used supervised exercise interventions and others used unsupervised interventions. Exercise intensity was classed as 'high' or 'low', duration of individual exercise sessions ranged from 20 minutes/session to 110 minutes/session, and study duration was from two to 18 months. Seventeen per cent of studies were classed as having an overall low risk of bias, 33% as moderate, and 49% as having a high risk of bias.The results shows that regular exercise significantly improved: 1) physical fitness (aerobic capacity, 24 studies, 847 participants: SMD -0.56, 95% CI -0.70 to -0.42; walking capacity, 7 studies, 191 participants: SMD -0.36, 95% CI-0.65 to -0.06); 2) cardiovascular dimensions (resting diastolic blood pressure, 11 studies, 419 participants: MD 2.32 mm Hg, 95% CI 0.59 to 4.05; resting systolic blood pressure, 9 studies, 347 participants: MD 6.08 mm Hg, 95% CI 2.15 to 10.12; heart rate, 11 studies, 229 participants: MD 6 bpm, 95% CI 10 to 2); 3) some nutritional parameters (albumin, 3 studies, 111 participants: MD -2.28 g/L, 95% CI -4.25 to -0.32; pre-albumin, 3 studies, 111 participants: MD - 44.02 mg/L, 95% CI -71.52 to -16.53; energy intake, 4 studies, 97 participants: SMD -0.47, 95% CI -0.88 to -0.05); and 4) health-related quality of life. Results also showed how exercise should be designed in order to optimise the effect. Other outcomes had insufficient evidence. AUTHORS' CONCLUSIONS There is evidence for significant beneficial effects of regular exercise on physical fitness, walking capacity, cardiovascular dimensions (e.g. blood pressure and heart rate), health-related quality of life and some nutritional parameters in adults with CKD. Other outcomes had insufficient evidence due to the lack of data from RCTs. The design of the exercise intervention causes difference in effect size and should be considered when prescribing exercise with the aim of affecting a certain outcome. Future RCTs should focus more on the effects of resistance training interventions or mixed cardiovascular- and resistance training as these exercise types have not been studied as much as cardiovascular exercise.

Abstract
Hypertension (HTN) is a highly prevalent risk factor for cardiovascular (CV), cerebrovascular, and renal diseases and disproportionately affects African Americans (AAs). It has been shown that promoting the adoption of healthy lifestyles, ones that involve best practices of diet and exercise and abundant expert support, can, in a healthcare setting, reduce the incidence of hypertension in those who are at high risk. In this paper, we will examine whether similar programs are effective in the AA church-community-based participatory research settings, outside of the healthcare arena. If successful, these church-based approaches may be applied successfully to reduce the incidence and consequences of hypertension in large communities with potentially huge impact on public health.

Abstract
Hypertension (HTN) is a leading cause of cardiovascular and cerebrovascular diseases. Lifestyle modification may be the preferential approach to prevent and control HTN. The purpose of this study was to evaluate the effects of a community intervention program, which focused on improving the HTN knowledge, diets and lifestyles in a rural Chinese area. The study was carried out in a rural area of the Hubei Province from May 2003 to April 2006. A total of 1632 participants were recruited. Of the participants, 826 from the town of Xiaoxita and 806 from the town of Fenxiang were assigned to the intervention group (group I) and to the control group (group C), respectively. Group I participants underwent an intervention that included HTN education and dietary and lifestyle guidance. Group C participants were not subjected to an intervention. The outcome measures included HTN knowledge, dietary and lifestyle behaviors, and prevalence, awareness, treatment and control rates of HTN. Along with the changes in HTN education (P<0.05), the participants in group I exhibited a significantly greater improvement in dietary habits and lifestyle behaviors, including reducing salty food intake (13.6%), fat intake (22.9%) and alcohol consumption (9.6%), after 3 years in comparison with those in group C (21.7, 31.9 and 18%, respectively). The prevalence of HTN was significantly lower in group I (22.5%) than in group C (36%) after the intervention strategies. The study showed that the implementation of a community intervention program involving HTN education and lifestyle modifications for rural residents is a powerful approach to reduce HTN prevalence and improve long-term health outcomes.

Abstract
The morbidity and mortality benefits of lowering blood pressure (BP) in hypertensive patients are well established, with most individuals requiring multiple agents to achieve BP control. Considering the important role of the renin-angiotensin-aldosterone system (RAAS) in the pathophysiology of hypertension, a key component of combination therapy should include a RAAS inhibitor. Angiotensin receptor blockers (ARBs) lower BP, reduce cardiovascular risk, provide organ protection, and are among the best tolerated class of antihypertensive therapy. In this article, we discuss two ARB combinations (valsartan/hydrochlorothiazide [HCTZ] and amlodipine/valsartan), both of which are indicated for the treatment of hypertension in patients not adequately controlled on monotherapy and as initial therapy in patients likely to need multiple drugs to achieve BP goals. Randomized, double-blind studies that have assessed the antihypertensive efficacy and safety of these combinations in the first-line treatment of hypertensive patients are reviewed. Both valsartan/HCTZ and amlodipine/valsartan effectively lower BP and are well tolerated in a broad range of patients with hypertension, including difficult-to-treat populations such as those with severe BP elevations, prediabetes and diabetes, patients with the cardiometabolic syndrome, and individuals who are obese, elderly, or black. Also discussed herein are patient-focused perspectives related to the use of valsartan/HCTZ and amlodipine/valsartan, and the rationale for use of single-pill combinations as one approach to enhance patient compliance with antihypertensive therapy.
