RESUMEN

PURPOSE: Several diagnostic algorithms exist to detect sarcopenia in older adults. We compared the prevalence of sarcopenia according to the selected diagnostic algorithms. METHODS: This cross-sectional study compared the European Working Group of Sarcopenia in Older People (EWGSOP) 2010, updated EWGSOP 2019, the Foundation for National Institutes of Health (FNIH) and the International Working Group on Sarcopenia (IWGS) criteria in 778 outpatients of the Geriatric Clinic aged 60 to 89 years. Bioimpedance analysis (BIA) to estimate muscle mass, hand-held hydraulic dynamometer to measure muscle strength, the TUG test and gait speed to assess physical function were used. RESULTS: The prevalence of sarcopenia varied from 0% to 6.43% depending on the algorithm. For the majority of associations between the different definitions of sarcopenia the agreement was null or fair (Cohen's kappa between 0.2 and 0.4). Moderate agreement (Cohen's kappa between 0.4 and 0.6) was found for only three relationships. Nevertheless, for these three relationships, McNemar's test has given different results, indicating that even in the moderately agreeing algorithms, the shared diagnoses of sarcopenia concerned only part of subjects. CONCLUSIONS: According to diagnostic algorithms the prevalence of sarcopenia is low in independent community-dwelling older adults. The agreement between the different definitions is poor.

RESUMEN

A Good Practice is a practice that works well, produces good results, and is recommended as a model. MACVIA-ARIA Sentinel Network (MASK), the new Allergic Rhinitis and its Impact on Asthma (ARIA) initiative, is an example of a Good Practice focusing on the implementation of multi-sectoral care pathways using emerging technologies with real life data in rhinitis and asthma multi-morbidity. The European Union Joint Action on Chronic Diseases and Promoting Healthy Ageing across the Life Cycle (JA-CHRODIS) has developed a checklist of 28 items for the evaluation of Good Practices. SUNFRAIL (Reference Sites Network for Prevention and Care of Frailty and Chronic Conditions in community dwelling persons of EU Countries), a European Union project, assessed whether MASK is in line with the 28 items of JA-CHRODIS. A short summary was proposed for each item and 18 experts, all members of ARIA and SUNFRAIL from 12 countries, assessed the 28 items using a Survey Monkey-based questionnaire. A visual analogue scale (VAS) from 0 (strongly disagree) to 100 (strongly agree) was used. Agreement equal or over 75% was observed for 14 items (50%). MASK is following the JA-CHRODIS recommendations for the evaluation of Good Practices.

RESUMEN

BACKGROUND/OBJECTIVES: To estimate the potential association of three distinct nutritional status measures (body mass index (BMI), calf circumference (CC) and the Mini Nutritional Assessment (MNA)) with health-related quality of life (HRQL) assessed with Euroqol 5D questionnaire in different populations of elderly people in Poland. SUBJECTS/METHODS: The study group was comprised of 1003 community-dwelling subjects from the urban environment, 890 subjects from the rural environment and 879 subjects from an institutional environment (nursing homes). Bivariate and multivariate associations were identified between nutritional status measures and HRQL adjusted for demographic and social variables, health status, physical function and mental status. RESULTS: Nutrition status indices (BMI, CC and MNA) were generally higher in the urban than in the rural environment and clearly worse in institutionalised elderly. In both community-dwelling groups, BMI and CC were negatively related to several Euroqol scores. In institutional residents, of opposite relationships were observed: higher values of these variables were connected with less frequent reporting of problems in Euroqol. In all the three groups, associations between HRQL scores and MNA were very similar: higher values of MNA were significantly connected with less frequent reporting of problems in Euroqol. CONCLUSIONS: BMI and CC, as overweight/obesity measures, are independent predictors of lower HRQL in urban and rural community-dwelling seniors and higher HRQL in institutionalised elderly. Poor nutritional state as measured by MNA is a similar determinant of well-being in all the three environments. This different relationship of popular overweight/obesity measures to HRQL should be taken into account while designing care for older people.

RESUMEN

OBJECTIVE: To assess the usefulness in different populations of elderly people in Poland of both modified versions of Mini Nutritional Assessment Short-Forms (MNA-SFs) with a three-category scoring classification: one using BMI (MNA-SF-BMI) and another using calf circumference (MNA-SF-CC). SETTING AND PARTICIPANTS: A group of 932 community-dwelling subjects from the urban environment, 812 subjects from the rural environment and 859 subjects from an institutional environment (nursing homes). MEASUREMENTS: Agreement between both MNA-SFs and the MNA full form. RESULTS: MNA-SF-BMI correctly classified 84.12%, 82.51% and 81.84% of subjects from urban, rural and institutional environment, respectively. For MNA-SF-CC those values were 82.4%, 71.8% and 76.6%, respectively. The sensitivity and specificity of MNA-SF-BMI and MNA-SF-CC against full MNA in screening for "at risk/malnutrition" and "malnutrition" were generally very high, except for relatively lower sensitivity (74.1%) when screening for "malnutrition" with MNA-SF-CC in nursing homes. CONCLUSION: Both MNA-SFs can be recommended as screening tools in assessing the nutritional state of the community-dwelling and institutionalised elderly in Poland. The full version of the MNA confirmed the results of MNA-SFs in this group. The "classic" MNA-SF using BMI was found to perform better than the MNA-SF-CC. The MNA-SF-CC should be used only when measuring BMI is not possible. While using MNA-SF-CC in nursing homes, a higher MNA-SF-CC cut-point of eleven should be rather used in this population to screen for "at risk/malnutrition".

RESUMEN

We examined simultaneously the influence of age as well as both current and historical habitual physical activity (PA) on aerobic (physical working capacity - PWC) and anaerobic (Pmax) power in 354 men aged 20.2-87.6 yrs. All the participants performed the graded aerobic exercise test and 8-second explosive power tests on a bicycle ergometer. Current leisure time physical activity (LTPA) and lifetime historical LTPA were assessed. The decline in Pmax/kg (10.3% per decade) was higher than in PWC/kg (7.5% per decade). Correlation coefficients for current LTPA and aerobic indices were higher than for current LTPA and anaerobic indices. In a multiple stepwise regression, current LTPA had the main effect on PWC/kg, whereas age had the main effect on Pmax/kg. Aerobic power was related to all measures of historical PA questionnaire, while anaerobic power - only to those historical measures which pertained to adolescence and younger years of adulthood. We conclude that the age-associated decline in anaerobic power is steeper than that of aerobic power. Habitual endurance-type LTPA increases aerobic but not anaerobic fitness throughout the adult lifespan. Anaerobic fitness indices are higher in young active vs sedentary men but this difference is not discernible as early as in the middle age.

RESUMEN

We explored the relationship of current and lifetime physical activity (PA) with upper respiratory tract infections (URTI) symptomatology in 142 male volunteers aged 33 to 90. They participated in baseline and one-year follow-up examinations and fulfilled the log books for daily recording of URTI symptomatology during the whole year. PA was assessed by the Seven Day Recall PA Questionnaire and the Historical Leisure Activity Questionnaire. Number of URTI episodes per year and the number of days with URTI per year were significantly inversely associated with the follow-up 7-Day Recall Hard score (rho = - 0.21; p = 0.013 and rho = - 0.18; p = 0.032, respectively). In logistic regression model, after adjustment for age and anthropometric data, the subjects with high follow-up 7-Day Recall Hard score (dichotomised as high vs. low) had a lower probability of having at least 2 URTI episodes per year (OR = 0.38; CI = 0.18 - 0.78), lower probability of having at least 3 URTI episodes per year (OR = 0.42; CI = 0.20 - 0.87), and lower probability of having at least 15 days with URTI (OR = 0.36; CI = 0.15 - 0.88). URTI symptomatology was not related to cardiorespiratory fitness or any measures of the historical PA questionnaire. We conclude that in middle-aged and older men the symptomatology of URTI over long periods of time is inversely related to current but not to lifetime PA.

RESUMEN

The study examined the association of nutritional status, obesity and physical activity (PA) with health-related quality of life (HRQL) in the elderly, and whether this relationship persists after controlling for confounders attributable to comorbidities, functional status and cognitive function. A total of 300 community-dwelling persons (177 women and 123 men) between 66 and 79 years of age were randomly chosen from all inhabitants of one district of the city of Lodz (Poland). HRQL was assessed with the Euroqol 5D questionnaire. PA was assessed by two questionnaires: the Seven Day Recall PA Questionnaire and the Stanford Usual Activity Questionnaire. Comorbidities, nutritional state (Mini Nutritional Assessment questionnaire - MNA), physical disability, cognitive function and psychological state were also assessed. In bivariate relationships body mass index (BMI), waist-to-hip ratio (WHR) and the percentage of body fat were negatively related to several HRQL scores both in women and men. Similarly, many HRQL scores were positively related to PA indices in both genders. In multivariate relationships, after adjustments for age, gender, smoking status, number of medications taken, comorbidities and geriatric physical and cognitive function, BMI predicted lower mobility while the percentage of body fat independently contributed to more frequent pain/discomfort and anxiety/depression problems. An adequate MNA added to a higher usual activity score, while a higher Stanford Moderate PA Index predicted better overall perceived health state. These results indicate that excess body fatness and sedentary lifestyle have, together with several functional and medical comorbidities, an independent contribution to inferior HRQL in community dwelling older subjects.

RESUMEN

OBJECTIVE: Lower amounts of circulating anabolic hormones are thought to accelerate the age related decline in muscle mass and function. Replacement therapies are promising interventions but there are problems with these therapies. Thus alternative strategies should be developed. The age related changes in hormonal status may be probably influenced by exercise. The purpose of this study was: a) to confirm with other methods, more adapted for elderly people, the results of a previous study that has shown relationship between physical activity (PA) and quadriceps muscle function with dehydroepiandrosterone sulphate (DHEAS), insulin like growth factor-1 (IGF-1). Quadriceps muscle power (Pmax) is measured in this new work with a recently developed leg extensor machine and, b) to complete the results of the first study examining simultaneously the relationship between PA, Pmax and cardiorespiratory fitness (VO2max) with DHEAS, IGF-1 and testosterone in a group of healthy elderly people. METHODS: Fifty independent, community dwelling elderly subjects (25 mens and 25 womens) aged from 66 to 84 volunteered to participate in the study. PA was evaluated by the questionnaire and expressed using two activity indices: mean habitual daily energy expenditure (MHDEE) and the daily energy expenditure corresponding to leisure time sports activities (Sports Activity). Pmax and optimal shortening velocity (vopt) were measured on a Ergopower dynamometer. The Pmax was expressed relative to body mass, Pmax/kg (W kg-1), and relative to the mass of the two quadriceps muscles, Pmax/Quadr (W.kgQuadr-1). VO2max has been measured during a maximal treadmill exercise. RESULTS: In women, IGF-1 correlated significantly with MHDEE (r = 0.54, P = 0.004), Pmax/kg (r = 0.54, P = 0.004) and Pmax/Quadr (r = 0.46, P = 0.02), whereas DHEAS with MHDEE (r = 0.54, P = 0.004), Sports Activity (r = 0.65, P < 0.001), VO2max (r = 0.46, P = 0.02), Pmax/kg (r = 0.46, P = 0.02) and Pmax/Quadr (r = 0.55, P = 0.004). No such correlation was found in men. CONCLUSION: These findings confirm that in healthy elderly women physical activity, cardiorespiratory fitness and quadriceps muscle function are similarly related to levels of circulating DHEAS and IGF-1 suggesting a favourable influence of exercise on anabolic hormonal production in the elderly.

RESUMEN

The choice of an appropriate structure coding scheme is the secret to success in QSAR studies. Depending on the problem at hand, 2D or 3D descriptors have to be chosen; the consideration of electronic effects might be crucial, conformational flexibility has to be of special concern. Artificial neural networks, both with unsupervised and with supervised learning schemes, are powerful tools for establishing relationships between structure and physical, chemical, or biological properties. The EROS system for the simulation of chemical reactions is briefly presented and its application to the degradation of s-triazine herbicides is shown. It is further shown how the simulation of chemical reactions can be combined with the simulation of infrared spectra for the efficient identification of the structure of degradation products.

RESUMEN

BACKGROUND: Malnutrition is a widespread but largely unrecognized problem in aged patients, more so as it is a contributing factor to the increased morbidity and mortality in this age group. Since direct measurements of body composition are not possible in a large number of patients, good anthropometric reference data are fundamental in assessing the nutritional state of elderly people. OBJECTIVE: To examine the efficacy of calf circumference (CC) measurement for assessing the nutritional state of the elderly. METHODS: The nutritional state was assessed by anthropometric and biological measurements in 911 elderly patients consecutively admitted to a geriatric unit. In the first instance, univariate analysis was performed for CC and other nutritional parameters. Linear and multiple stepwise regressions were performed to study the association between anthropometric or biological parameters and CC. At a later stage, the specificity, sensitivity and the optimal cutoff CC were established for 2 groups of patients: malnourished and controls. Finally, patients were classified according to this cutoff in order to verify the efficacy of CC in assessing their nutritional state. RESULTS: The results of univariate analysis showed significant correlations between CC and other nutritional anthropometric markers (r = 0.706, p < 0.0001 with body mass index (BMI) and r = 0.661, p < 0.0001 with fat free mass) and biological markers (r = 0.219, p < 0.0001 with albumin and r = 0.162, p < 0.0001 with transthyretin). Multiple regression confirmed associations between CC and tricipital skinfold thickness (p < 0.0001), fat free mass (p < 0.0001), BMI (p < 0.0001), and serum albumin (p < 0.0001; r(2) = 0.561). The optimal cutoff for CC was found to be 30.5 cm for both men (sensitivity 73.2%, specificity 72.8%) and women (sensitivity 78.8%, specificity 61.1%). The classification of patients according to this discriminating factor was confirmed for the optimal cutoff value. CONCLUSION: Calf circumference is a pertinent marker of nutritional state. The cutoff of 30.5 cm provides a good diagnostic capacity.

RESUMEN

Plasma levels of dehydroepiandrosterone sulphate (DHEAS), insulin-like growth factor-I (IGF-I), and testosterone decline with ageing. These hormones share some biological activities which counteract the aging processes: increase in fat-free mass, decrease of adipose tissue and globally increased fitness and well being. It seems that lower levels of these hormones may reflect partially lower physical activity and fitness of older subjects. If further longitudinal studies confirm this, regular participation in exercise training would become a useful alternative to hormone replacement therapy.

RESUMEN

Substance identification in analytical chemistry is usually performed by comparing an experimental spectrum with a reference spectrum. Especially in environmental chemistry, reference spectra from databases are only available for a limited number of compounds. The combination of the reaction prediction system EROS and of infrared spectra simulation is a powerful tool for computer-assisted substance identification. First, possible degradation products of a chemical are predicted and then the infrared spectra of all these compounds are simulated. Comparison of the simulated infrared spectra with experimental spectra allows one to identify the structure of compounds. The method is demonstrated with the example of s-triazine herbicides.

RESUMEN

BACKGROUND: To examine the influence of long-term modifications in habitual physical activity (PA) on resting total testosterone (TT) concentrations in a group of healthy elderly subjects. EXPERIMENTAL DESIGN: 6-month prospective study. SETTING: University research departments of exercise physiology and geriatric medicine. PARTICIPANTS: thirty-one independent, community dwelling elderly subjects (16 men and 15 women) aged > 65 who volunteered to participate. INTERVENTIONS: correlational study. MEASURES: PA was evaluated by a questionnaire QAPSE (Questionnaire d Activité Physique Saint-Etienne) and expressed by two activity indices: mean habitual daily energy expenditure (MHDEE) and daily energy expenditure corresponding to leisure time sports activities (Sports activity index). RESULTS: Changes in resting TT concentrations were not related to changes in MHDEE (r = -0.28; p = 0.30 and r = -0.001; p=0.99) and Sports activity (r = -0.30; p = 0.26 and r = -0.05; p = 0.85) in men and women, respectively. Similarly, relative (%) changes in TT were not related to relative changes in MHDEE (r = -0.16; p=0.55 and r = 0.17; p=0.55) and Sports activity (r = -0.11; p=0.68 and r = 0.02; p = 0.92). CONCLUSIONS: The levels of habitual PA undertaken by an average senior do not appear to affect TT levels in healthy active elderly men and women.

RESUMEN

OBJECTIVE: The purpose of this study was to simultaneously validate 10 physical activity (PA) questionnaires in a homogenous population of healthy elderly men against the reference method: doubly labeled water (DLW). DESIGN: Cross-sectional study. SETTING: Community-based sample from Lyon, France. PARTICIPANTS: Nineteen healthy old men (age 73.4 +/- 4.1 years), recruited from various associations for elderly people in Lyon, agreed to participate in the study. MEASUREMENTS: The questionnaire-derived measures (scores) were compared with two validation measures: DLW and maximal oxygen uptake (VO2max). With the DLW method three parameters were calculated: (1) total energy expenditure (TEE), (2) physical activity level (PAL), i.e., the ratio of TEE to resting metabolic rate, (3) energy expenditure of PA. RESULTS: Relative validity. Correlation between the questionnaires and TEE ranged from 0.11 for the Yale Physical Activity Survey (YPAS) total index to 0.63 for the Stanford usual activity questionnaire. This questionnaire also gave the best correlation coefficients with PAL (0.75), and with VO2max (0.62). Significant results with TEE measured by the DLW method were also obtained for college alumni sports score, Seven Day Recall moderate activity, and Questionnaire d'Activité Physique Saint-Etienne sports activity (r = 0.54, r = 0.52, and r = 0.54, respectively). Absolute validity. No difference was found between PA measured by the Seven Day Recall or by the YPAS and DLW, on a group basis. The limits of agreement were wide for all the questionnaires. CONCLUSIONS: Only a few questionnaires demonstrated a reasonable degree of reliability and could be used to rank healthy older men according to PA. Correlation coefficients were best when the Stanford Usual Activity Questionnaire was compared with all the validation measures. The two questionnaires reporting recent PA, the Seven Day Recall, and YPAS accurately assessed energy expenditure for the group. The individual variability was high for all the questionnaires, suggesting that their use as a proxy measure of individual energy expenditure may be limited.

RESUMEN

Regular physical activity plays an important role in nonpharmacologic management of hyperlipidemia, in both the primary and secondary prevention of coronary heart disease. Training intensity and duration, health status (especially the presence of cardiovascular disease), and concomitant changes in body mass and dietary habits are the most important factors that can modify the physical activity-blood lipid profile relationship in the elderly. The benefit of regular exercise goes beyond direct influence on blood lipids; it aids in reducing weight, decreasing fat mass, increasing lean body mass, reducing elevated blood pressure, and increasing insulin sensitivity. Regular physical activity has become widely recommended as an important element of healthy and successful aging and should be encouraged in individuals without contraindications. (c)2001 CHF, Inc.

RESUMEN

Red wine has been a subject of much interest of professionals representing different fields of medicine. However, most of scientific studies have been searching for the reason of so called French paradox, which means that in France and other mediterranean countries the morbidity and mortality due to ischaemic heart disease is significantly lower than in other developed countries, in spite of relatively high consumption of fat and saturated fatty acids. The cardio-protective mechanism of red wine, although incompletely understood, is connected on one hand with the presence of ethanol which increases high-density lipoprotein cholesterol (HDL) and inhibits platelet aggregation, and on the other hand with the presence of polyphenols that have desirable biological properties. These include flavonoids, phenolic acids and stilbenes which are reputed to have antioxidant, vasorelaxing and antiplatelet properties. There is a considerable body of evidence indicating that regular consumption of red wine at moderate doses (200-400 ml a day) exerts a protective effect against ischaemic heart disease, other cardiovascular diseases, and perhaps diabetes, osteoporosis or some cancers. But, since alcohol intake involves a potential danger (risk of dependence, alcoholism, many organic diseases, migraine, allergies) medical recommendations of red wine consumption should be formulated very carefully.

RESUMEN

The relationship of quadriceps maximal muscle power (Pmax), corresponding optimal shortening velocity (v(opt)), and relative fatigability (Pmax%D) to maximal oxygen uptake (VO2max) and habitual physical activity (PA) was examined in healthy community-dwelling subjects (29 women and 25 men) aged more than 65 years old. PA was evaluated by a questionnaire and expressed using two activity indices: mean habitual daily energy expenditure (MHDEE) and the daily energy expenditure corresponding to leisure time sports activities (Sports Activity). In women, Pmax correlated positively with VO2max (r = .56) and with Sports Activity (rho = .41). Both Sports Activity and Pmax were significant independent predictors of VO2max and accounted for 62% of variance in VO2max. In men, v(opt) was significantly negatively related to MHDEE (r = -.59) and to Sports Activity (rho = -.40). Neither in women nor in men was Pmax%D correlated with VO2max or PA indices. The different relationship of Pmax and v(opt) with VO2max and PA indices suggests that habitual PA may be sufficient in active older women, but not in men, to positively influence quadriceps muscle function. These gender differences may suggest different approaches in exercise programming for elderly women and men.

RESUMEN

We examined the association between quadriceps muscle function and serum levels of dehydroepiandrosterone sulphate (DHEAS), insulin-like growth factor I (IGF-I) and testosterone in a group of healthy elderly people. Fifty-three independent, community-dwelling elderly subjects (26 men and 27 women) aged from 66 to 84 years volunteered to participate in the study. Physical activity (PA) was evaluated by a questionnaire. Quadriceps maximal muscle power (Wmax) and optimal shortening velocity (v(opt)) were measured on a friction-loaded non-isokinetic cycle ergometer. The Wmax is expressed in relation to body mass (W(max/kg), W x kg(-1)), and in relation to the mass of the two quadriceps muscles (W(max/Quadr), W x kg(Quadr(-1))). In women, when adjusted for age, anthropometric measurements and PA indices, IGF-I correlated significantly with W(max/kg) (partial correlation: r = 0.59; P = 0.001), W(max/Quadr) (r = 0.58; P = 0.002) and v(opt) (r = 0.53; P = 0.004), whereas DHEAS was correlated significantly with W(max/kg) (r = 0.54; P = 0.003) and W(max/Quadr) (r = 0.58; P = 0.002). No such correlation was found in men. These findings indicate that in healthy elderly women lower values for quadriceps muscle Wmax and v(opt) are related, independently of age, anthropometric measurements and PA indices, to lower circulating levels of DHEAS and IGF-I.

RESUMEN

In order to define the amount of physical activity appropriate in primary prevention of coronary heart disease (CHD), we have compared the effects during 5 years of physical activity in four groups of middle-aged men with different but stable approximate metabolic costs of leisure time sports activities (AMCSA): sedentary (n = 40; 0 kcal per week), low activity (n = 31; 1-999 kcal per week), moderate activity (n = 56; 1,000-1,999 kcal per week), and high activity (n = 71; > or = 2,000 kcal per week). Time related increase of body mass and BMI was more pronounced in lower activity groups. Changes in HDL cholesterol were more favourable in the high activity group as compared to sedentary and low activity groups. The increase of diastolic blood pressure (DBP) in the sedentary group was statistically significantly different from the decrease of DBP observed in both moderate and high activity groups. We conclude that favourable long-term stabilization of most coronary risk factors is achievable with physical activity energy expenditure above 1,000 kcal per week. Physical activity-related energy expenditure > or = 2,000 kcal per week is associated with some additional benefits, especially with a favourable modification of HDL cholesterol level.
