Objective: To identify determinants of use of smoking cessation aids among current and former smokers in the European Union (EU). Methods: Data from n=9921 current and ex-smokers from 27 European countries (Eurobarometer 77.1, February-March 2012) were analysed. Multivariate binary logistic regression was used to assess for correlates of use of any recommended aid with proven efficacy, defined as use of pharmacotherapy or psychosocial counselling (p<. 0.05). The regression analyses assessed for socio-demographic characteristics, EU region, as well as scope of national smoking cessation policies. Results: Among current smokers who had made a quit attempt and ex-smokers, 19.9% had used any recommended aid with proven efficacy. Respondents from Northern (adjusted odds ratio [aOR]=1.90), Western (aOR=3.21) and Eastern Europe (aOR=1.69) were more likely to have used an efficacious smoking cessation aid compared to respondents from Southern Europe (all p<. 0.05). Respondents in countries with comprehensive tobacco cessation programmes that offered cost-covered national quit lines, medication, and other cessation services had increased likelihood of using efficacious cessation aids (OR=1.29; 95% Confidence Interval: 1.07-1.55). Conclusions: These findings underscore the need for enhanced and sustained efforts to ensure increased access to cessation services and aids as part of a comprehensive tobacco control programme. © 2014 Elsevier Inc.

Objective: To investigate whether having multiple risk factors for cardiovascular disease is associated with having had cholesterol and blood pressure measurements in the past year. Methods: Cross-sectional data from the 2009 Eurobarometer survey (wave 72.3), were analysed. Self-reported data on smoking, fruit consumption, alcohol consumption and physical activity were collected from 15,287 individuals aged between 40 and 75. years from 27 European countries. Results: Having had a cholesterol test was inversely associated with smoking (OR = 0.85; 95% CI:0.74-0.96), high alcohol (OR = 0.81; 95% CI: 0.66-0.99) and low fruit consumption (OR = 0.83; 95% CI: 0.73-0.93), but not with sedentary lifestyle. Having had a blood pressure test was also inversely associated with smoking (OR = 0.84; 95% CI: 0.73-0.97), high alcohol (OR = 0.74; 95% CI: 0.60-0.92) and low fruit consumption (OR = 0.73; 95% CI: 0.64-0.84). The more risk factors reported by respondents, the less likely they were to have had a preventive test in the past year. Individuals with all four risk factors were less likely to have had their cholesterol (OR = 0.42; 95% CI: 0.26-0.68) and blood pressure (OR = 0.45; 95% CI: 0.27-0.75) measured compared to individuals with no risk factors. Conclusions: Screening strategies in Europe need to be revised, as Europeans at the highest risk for cardiovascular diseases were the least likely to have received cholesterol or blood pressure tests. © 2014 Elsevier Inc.

Near infrared spectroscopy (NIRS) is a simple, noninvasive method for estimating tissue oxygenation and microcirculation function. NIRS has been utilized in patients with chronic heart failure, peripheral vascular disease, chronic obstructive pulmonary disease, renal failure and other diseases. This brief review highlights the progress of the application of NIRS to evaluate skeletal muscle oxygenation during exercise in these populations. Relevance to industry: Projects in ergonomics research need methods to assess the capability of healthy and diseased people to perform particular tasks and to prevent health and performance-related complications both during routine activities and in the long run. NIRS provides quantitative oxygenation indices for the recognition of significant disabilities. Therefore, it constitutes a valuable tool for direct observations and prospective studies in the workplace. NIRS-derived data concerning occupational health and human-work interactions can contribute to optimal design of work environments and task allocation. © 2009 Elsevier B.V. All rights reserved.

Background: Patients with chronic heart failure (CHF) usually experience poor quality of life (QoL). Psychosocial interventions tend to affect QoL in CHF. The aim of this study was to explore: 1) the effectiveness of psychosocial interventions on patients' QoL; 2) the magnitude of this effect; and 3) factors that appear to moderate the reported effect on QoL. Methods and Results: Meta-analysis of the data of 1,074 intervention patients and 1,106 control patients from 16 randomized controlled trials (RCTs) that reported QoL measures in treatment and control groups before and after a psychosocial intervention. Subgroup analyses were conducted between: 1) face-to-face versus telephone interventions; 2) interventions that included only patients versus those that included patients and their caregivers; and 3) interventions conducted by a physician and a nurse only, versus those conducted by a multidisciplinary team. Psychosocial interventions improved QoL of CHF patients (standardized mean difference 0.46, confidence interval [CI] 0.19-0.72; P < .001). Face-to-face interventions showed greater QoL improvement compared with telephone interventions (χ2 = 5.73; df = 1; P < .02). Interventions that included caregivers did not appear to be significantly more effective (χ2 = 1.12; df = 1; P > .29). A trend was found for multidisciplinary team approaches being more effective compared with nonmultidisciplinary approaches (χ2 = 1.96; df = 1; P = .16). Conclusions: A significant overall QoL improvement emerged after conducting psychosocial interventions with CHF patients. Interventions based on a face-to-face approach showed greater benefit for patients' QoL compared with telephone-based approaches. No significant advantage was found for interventions conducted by a multidisciplinary team compared with a physician and nurse approach, or for psychosocial interventions which included patients' caregivers compared with patient-only approaches. © 2013 Elsevier Inc.

Purpose: The loss of lean muscle mass and muscle strength is a common problem in chronic heart failure (CHF) patients. Endurance training is efficient in improving patient exercise capacity. This study sought to evaluate the additional effects of strength training on muscle strength and body composition in chf patients participating in an interval training program. METHODS:: Twenty consecutive, stable CHF patients participated in a rehabilitation program. Subjects were randomly assigned to aerobic (n = 10) or combined aerobic plus strength training group (n = 10). Aerobic group performed interval training on cycle ergometers. Strength training incorporated exercises for various muscle groups, including quadriceps, hamstrings, biceps brachii, and the deltoids. Both regimes were of the same duration. Body composition was evaluated by whole-body dual energy x-ray absorptiometry and quadriceps strength by the sum of the 2-repitition maximum (2-RM) test for each leg. Peak oxygen uptake ((Equation is included in full-text article.)) and peak work load (Wpeak) as well as oxygen uptake ((Equation is included in full-text article.)) and workload at anaerobic threshold (WAT) were evaluated by a symptom limited cardiopulmonary exercise testing. RESULTS:: Concerning leg lean mass, no significant within-subjects or between-groups changes were observed (P > .05). Both groups improved in 2-RM test (P < .05), while a significant difference was observed between groups (P < .05). (Equation is included in full-text article.)and (Equation is included in full-text article.)and Wpeak and WAT were equally improved between training groups (P < .05). CONCLUSIONS:: Combined aerobic interval and strength training induces a greater benefit than interval training alone on muscle strength in CHF patients. Adaptations other than hypertrophy, such as muscle fiber type alterations and/or neuromuscular adjustments, may account for these results. © 2011 Lippincott Williams & Wilkins, Inc.
