Full Text Available The purpose of this study was to compare selective attention deficit in elderly Alzheimer patients and healthy elderly individuals using the dual task. Therefore, 23 subjects (11 females and 12 males age 62 to 81 years; 13 patients with Alzheimer's disease (AD and 10 healthy elderly subjects (EHI with normal cognitive function participated in this study. people with Alzheimer's disease. healthy people was selected through some neurologist identified Short Portable Mental Status Questionnaire (SPMSQ. After obtaining the average number of correct counting of months of the year in both simple and difficult cognitive task the overall error (E or Root Mean Squared Error (RMSE, and variable error (VE were calculated for the tracking task. Then each person performed 10 tasks simultaneously (under Dual-task in both simple and difficult mode. Analysis of variance in cognitive tasks showed that there was a significant interaction between task difficulty and risk of AD (p0.05. In other words, at dual conditions of tracking task, accuracy and consistency of both groups was equally reduced, which was most prominent in difficult conditions. This decrease indicates increased interference at response level due to defects in the mechanisms of selective attention in dual cognitive and tracking tasks and both groups.

Full Text Available Abstract Background/Aims Neurological abnormalities have been reported in normal aging population. However, most of them were limited to extrapyramidal signs and soft signs such as motor coordination and sensory integration have received much less attention. Very little is known about the relationship between neurological soft signs and neurocognitive function in healthy elder people. The current study aimed to examine the underlying relationships between neurological soft signs and neurocognition in a group of healthy elderly. Methods One hundred and eighty healthy elderly participated in the current study. Neurological soft signs were evaluated with the subscales of Cambridge Neurological Inventory. A set of neurocognitive tests was also administered to all the participants. Structural equation modeling was adopted to examine the underlying relationship between neurological soft signs and neurocognition. Results No significant differences were found between the male and female elder people in neurocognitive function performances and neurological soft signs. The model fitted well in the elderly and indicated the moderate associations between neurological soft signs and neurocognition, specifically verbal memory, visual memory and working memory. Conclusions The neurological soft signs are more or less statistically equivalent to capture the similar information done by conventional neurocognitive function tests in the elderly. The implication of these findings may serve as a potential neurological marker for the early detection of pathological aging diseases or related mental status such as mild cognitive impairment and Alzheimer's disease.

The prevalence of non-alcoholic fatty liver disease (NAFLD) is rising, an increase that may be associated with changes in lifestyle such as unhealthy dietary patterns. Although advanced age is a risk factor for NAFLD, no studies reporting this association in the elderly population were found. In the present study, the association between dietary patterns and NAFLD in the elderly was assessed. A study including 229 older adults was conducted. NAFLD diagnosis was defined as individuals whose ultrasound examination disclosed hepatic steatosis at any stage, in the absence of excess intake of alcoholic beverages. Dietary patterns were obtained by principal components analysis. Mean scores and standard errors of each dietary pattern were calculated for the groups with and without NAFLD, and mean scores of the two groups were compared using the Mann-Whitney U test. The prevalence ratios and 95 % CI were estimated for each tertile of the dietary pattern adherence scores using Poisson multiple regression models with robust variance. A total of 103 (45 %) elderly with NAFLD and four dietary patterns were identified: traditional, regional snacks, energy dense and healthy. Mean scores for adherence to the healthy pattern in the groups with and without NAFLD differed. NAFLD was inversely associated with greater adherence to the healthy pattern and directly associated with the regional snacks, after adjustment for confounders. In conclusion, healthy dietary pattern is inversely associated with NAFLD in elderly.

Full Text Available Abstract Background Hemispherical asymmetry, sex differences and age-related changes have been reported for the human brain. Meanwhile it was still unclear the presence of the asymmetry or sex differences in the human brain occurred whether as a normal development or as consequences of any pathological changes. The aim of this study was to investigate hemispherical asymmetry, sex differences and age-related changes by using a tract-based analysis in the nerve bundles. Methods 40 healthy elderly subjects underwent magnetic resonance diffusion tensor imaging, and we calculated fractional anisotropy (FA and apparent diffusion coefficient (ADC values along the major white matter bundles. Results We identified hemispherical asymmetry in the ADC values for the cingulate fasciculus in the total subject set and in males, and a sex difference in the FA values for the right uncinate fasciculus. For age-related changes, we demonstrated a significant increase in ADC values with advancing age in the right cingulum, left temporal white matter, and a significant decrease in FA values in the right superior longitudinal fasciculus. Conclusion In this study, we found hemispherical asymmetry, sex differences and age-related changes in particular regions of the white matter in the healthy elderly. Our results suggest considering these differences can be important in imaging studies.

Creativity, which presumably involves various connections within and across different neural networks, reportedly underpins the mental well-being of older adults. Multiscale entropy (MSE) can characterize the complexity inherent in EEG dynamics with multiple temporal scales. It can therefore provide useful insight into neural networks. Given that background, we sought to clarify the neurophysiological bases of creativity in healthy elderly subjects by assessing EEG complexity with MSE, with emphasis on assessment of neural networks. We recorded resting state EEG of 20 healthy elderly subjects. MSE was calculated for each subject for continuous 20-s epochs. Their relevance to individual creativity was examined concurrently with intellectual function. Higher individual creativity was linked closely to increased EEG complexity across higher temporal scales, but no significant relation was found with intellectual function (IQ score). Considering the general "loss of complexity" theory of aging, our finding of increased EEG complexity in elderly people with heightened creativity supports the idea that creativity is associated with activated neural networks. Results reported here underscore the potential usefulness of MSE analysis for characterizing the neurophysiological bases of elderly people with heightened creativity.

To describe the prevalence of guidance on healthy habits received from health professionals by elderly and its relation to socioeconomic demographic, behavioral and health indicators, and the type of services. Cross sectional population based study including individuals aged 60 years or more in the urban area of Pelotas, Rio Grande do Sul, Brazil. Seven guidance on healthy habits were evaluated: weight control, reduction in salt, sugar and fat intake, physical activity practice, not smoking and not drinking alcohol. Among the 1,451 elderly interviewed, 1,281 (88.3%) consulted in the last year. The orientations more refereed were to fat (61.7%) and salt (61.5%) intake reduction and physical activity (58.2%). Elderly who consulted three times or more and in services financed by the Unified Health System received more guidance. Those elderly from the socioeconomic classes A/B were more likely to receive guidance for weight control (RP = 1.27; 95%CI 1.06 - 1.70) and physical activity (RP = 1.34; 95%CI 1.06 - 1.69). The orientation from health professionals were uncommon and, in some cases, unfocused.

The purpose of this study was to evaluate the prevalence of sarcopenia in a cohort of healthy community-dwelling elderly in an urban area in Barcelona (Spain) for native benchmarks and compare them with those published in other geographical areas. We prospectively evaluated a series of 200 healthy elderly in the community with preserved functional capacity and absence of cognitive impairment. We performed a comprehensive geriatric assessment and determined anthropometric data, muscle mass (MM) and the muscle mass index (MMI). Assessment of muscle mass was performed by bioelectrical impedance analysis (BIA). The cut-off point for defining sarcopenia MMI was established as less than 2 SD of the mean of a reference group comprising 220 healthy volunteers (20-42 years) in the same area. Results were compared with studies undertaken in the USA, France and Taiwan. The cut-off points obtained were 8.31 Kg/m(2) for men and 6.68 Kg/m2 for women, being similar to those observed in France and Taiwan but different from the USA. The prevalence of sarcopenia observed was 33% for elderly women and 10% for males. On comparison of the prevalence of sarcopenia in the four populations, we observed some differences, particularly in males. We have defined reference values for sarcopenia, determined by BIA, in our setting. We also observed a remarkable prevalence of sarcopenia in the healthy elderly community, especially in females, showing some differences from those in other geographical regions.

Stress and Cognitive Reserve as independent factors of neuropsychological performance in healthy elderly

João Carlos Centurion Cabral

Full Text Available Abstract Exposure to high levels of cortisol and self-reported stress, as well as cognitive reserve, have been linked to Alzheimer’s disease pathology. However, there are no studies on the interaction of these variables. The present study aims to assess the associations of measures of cortisol, self-reported stress, and cognitive reserve with neuropsychological performance in healthy elderly people; besides, to test the interactions between these variables. Cross-sectional analyzes were conducted using data on stress, cognitive reserve and clinical conditions in 145 healthy elderly adults. A neuropsychological battery was used to assess executive functions, verbal memory and processing speed. Measurement of salivary cortisol at the circadian nadir was taken. A negative association between different stress measures and performance on tasks of memory, executive functions and processing speed was observed. Elderly people with higher cognitive reserve showed superior performance on all neuropsychological measures. No significant interaction between stress and cognitive reserve to neuropsychological performance was observed. These results indicate that older adults with high levels of stress and reduced cognitive reserve may be more susceptible to cognitive impairment.

DFT:B3LYP/3-21G theoretical insights on the confocal Raman experimental observations in skin dermis of healthy young, healthy elderly, and diabetic elderly women

In the confocal Raman spectra of skin dermis, the band area in the spectral region of proline and hydroxyproline varies according to the age and health condition of the volunteers, classified as healthy young women, healthy elderly women, and diabetic elderly women. Another observation refers to the intensity variation and negative Raman shift of the amide I band. To understand these effects, we adopted a model system using the DFT/B3LYP:3-21G procedure, considering the amino acid chain formed by glycine, hydroxyproline, proline, and alanine, which interacts with two and six water molecules. Through these systems, polarizability variations were analyzed to correlate its values with the observed Raman intensities of the three groups of volunteers and to assign the vibrational spectra of the skin dermis. As a way to correlate other experimental trends, we propose a model of chemical reaction of water interchange between the bonding amino acids, in which water molecules are attached with glucose by hydrogen bonds. The theoretical results are in accordance with the observed experimental trends.

A consensus on the diagnostic criteria for sarcopenia, a common syndrome in the elderly, has not been reached yet. Prevalence rates vary between studies due to the use of different criteria encompassing different measures, correction factors and cutoff points. This study compared prevalence rates of sarcopenia using nine sets of diagnostic criteria applied in two different elderly populations. The study population encompassed 308 healthy elderly participants (152 males, 156 females; mean age 74 years) and 123 geriatric outpatients (54 males, 69 females; mean age 81 years). Diagnostic criteria included relative muscle mass, absolute muscle mass, muscle strength and physical performance. Prevalence rates of sarcopenia varied between 0 and 15% in healthy elderly participants and between 2 and 34% in geriatric outpatients. This study clearly demonstrates the dependency of sarcopenia prevalence rates on the applied diagnostic criteria. © 2015 S. Karger AG, Basel.

Elderly people are subject to higher levels of oxidative stress than are young people. Vitamin E, as a powerful antioxidant residing mainly in biomembranes, may provide effective protection against oxidative membrane damage and resultant age-related deterioration, especially in the elderly. We hypothesized that appropriate levels of vitamin E supplementation would protect erythrocyte membranes from oxidative stress and thus improve membrane fluidity in healthy middle-aged and elderly people. To test this, we conducted a 4-month double-blind, randomized trial in which 180 healthy subjects (55-70 years old) were randomly divided into 4 groups: group C (control), and 3 treatment groups in which daily doses of 100 mg (VE1), 200 mg (VE2), and 300 mg (VE3) dl-α-tocopheryl acetate were administered. We measured plasma α-tocopherol concentration, malondialdehyde, and superoxide dismutase levels, erythrocyte hemolysis, and erythrocyte membrane fluidity at the beginning and end of the trial. After 4 months supplementation, plasma α-tocopherol concentrations in the 3 treatment groups had increased by 71%, 78%, and 95%, respectively (all P stress in healthy middle-aged to elderly people, at least in part by improving erythrocyte membrane fluidity and reducing erythrocyte hemolysis.

Comprehensive research for factors related to healthy lifestyles of the elderly is limited. The present study aimed to elucidate the factors associated with adherence to a healthy lifestyle by age groups. The present study was based on data from the 2005 Korea National Health and Nutrition Examination Survey. We calculated crude proportions and adjusted proportions of cigarette smokers, problem alcohol drinkers, and physically inactive people in two age groups (40-59 years and ≥60 years). We carried out multilevel analysis to elucidate factors associated with healthy lifestyles. Of 3194 respondents included in the analysis, 1154 (36.13%) were aged 60 years or older. Older participants smoked less (23.0% vs 17.4%) and exercised less frequently (52.4% vs 66.9%; all P elderly (OR 1.037, 95% CI 1.005-1.070). Different factors were associated with healthy lifestyles of elderly people when compared with middle-aged people. In addition, local tax per capita, an area level variable, was more likely to be associated with smoking in the elderly than the middle-aged group. © 2014 Japan Geriatrics Society.

Full Text Available Abstract Background Calprotectin is a calcium and zinc binding protein, abundant in neutrophils and is extremely stable in faeces. Faecal calprotectin is used as a non-specific marker for gastrointestinal inflammation. It has a good diagnostic precision to distinguish between irritable bowel syndrome and inflammatory bowel disease. Studies have established normal concentrations in healthy children; all these studies have been performed in high-income countries. The objective of this study was to determine the concentration of faecal calprotectin in apparently healthy children aged 0-12 years in urban Kampala, Uganda. Method We tested 302 apparently healthy children aged, age 0-12 years (162 female, 140 male in urban Kampala, Uganda. The children were recruited consecutively by door-to-door visits. Faecal calprotectin was analyzed using a quantitative enzyme-linked immunosorbent assay. Faeces were also tested for Helicobacter pylori (H. pylori antigen, for growth of enteropathogens and microscopy was performed to assess protozoa and helminths. A short standardized interview with socio-demographic information and medical history was obtained to assess health status of the children. Results In the different age groups the median faecal calprotectin concentrations were 249 mg/kg in 0 H. pylori or having other pathogens in the stool. Conclusion Concentrations of faecal calprotectin among healthy children, living in urban Ugandan, a low-income country, are comparable to those in healthy children living in high-income countries. In children older than 4 years, the faecal calprotectin concentration is low. In healthy infants faecal calprotectin is high. The suggested cut-off concentrations in the literature can be used in apparently healthy Ugandan children. This finding also shows that healthy children living under poor circumstances do not have a constant inflammation in the gut. We see an opportunity to use this relatively inexpensive test for

Determining the cause of pruritus relies on establishing the pattern of abnormal pruritus. The presence of gastrointestinal (GI) disease has also been helpful in determining the cause of pruritus. No study has systematically evaluated typical GI signs and pruritic behaviours in apparently healthy dogs. To evaluate owners' perceptions of pruritus and GI signs in apparently healthy dogs, and determine if age, breed, activity, diet or supplements affected these signs. Three hundred and fourteen apparently healthy dogs ≥ 12 months old with an unremarkable physical examination and no history of pruritus, otitis, skin/hair disease, metabolic or GI disease were enrolled. Thirty one veterinarians enrolled dogs after establishing their pruritus visual analog scale (PVAS) score and faecal consistency score (FCS); owners completed a comprehensive online survey regarding GI signs, possible pruritic behaviours, ear cleaning and sneezing. A PVAS score of ≤ 1.9 was recorded in 87.6% of dogs and the FCS was 2-3 in 94.9% of dogs. PVAS was positively correlated with paw licking/chewing, facial/muzzle rubbing, head shaking and sneezing. Scooting was positively correlated with sneezing. Over 96% of dogs had 1-3 bowel movements (BM) per day. Age was positively correlated with facial/muzzle rubbing, sneezing, coprophagia and borborygmi. The number of walks/day was positively correlated with paw licking/chewing, head shaking, sneezing, number of BM/day, coprophagia, belching, flatulence and borborygmi. A standard method of asking relevant questions was developed and the frequency of GI signs and many behaviours that may indicate pruritus in apparently healthy dogs was established. © 2015 ESVD and ACVD.

Full Text Available OBJECTIVE: We aimed to investigate how lean body mass is related to circulating Interleukin 18 (IL-18 and its association with metabolic syndrome (MetS among apparently healthy Chinese. METHODS: A population-based sample of 1059 Chinese men and women aged 35-54 years was used to measure plasma IL-18, glucose, insulin, lipid profile, inflammatory markers and high-molecular-weight (HMW-adiponectin. Fat mass index (FMI and lean mass index (LMI were measured by dual-energy X-ray absorptiometry. MetS was defined by the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian-Americans. RESULTS: Circulating IL-18 was positively correlated with LMI after adjustment for FMI (correlation coefficient = 0.11, P<0.001. The association with the MetS (odds ratio 3.43, 95% confidence interval 2.01-5.85 was substantially higher in the highest than the lowest quartile of IL-18 after multiple adjustments including body mass index. In the stratified multivariable regression analyses, the positive association between IL-18 and MetS was independent of tertiles of FMI, inflammatory markers and HMW-adiponectin, but significantly interacted with tertile of LMI (P for interaction = 0.010. CONCLUSION: Elevated plasma IL-18 was associated with higher MetS prevalence in apparently healthy Chinese, independent of traditional risk factors, FMI, inflammatory markers and HMW-adiponectin. More studies are needed to clarify the role of lean mass in IL-18 secretion and its associated cardio-metabolic disorders.

The aging of the population is a universal phenomenon with direct consequences upon the public health system. One of the main repercussions of the growth in this sector of the population is the increased prevalence of disorders such as dementia and depression which are very frequent among the elderly. The relationship between cardiovascular risk factors, dementia and depression have been addressed in many recent investigations. Objectives To evaluate the relationship of cognitive performance and depressive symptoms with cardiovascular risk in the elderly. Methods 94 high cardiovascular risk elderly patients and 160 healthy community elderly were evaluated cross-sectionally. The Mini Mental State Examination (MMSE) and the Geriatric Depression Scale (GDS-15) were used as the main measures. The cutoff for presence of depression was 6 on the GDS. Results The high cardiovascular risk elderly group showed significantly lower scores on the MMSE (p<0.001) and was significantly associated to depression (p<0.001), independently of education. The logistic regression analysis for depression as the dependent variable, age and group (healthy community or high cardiovascular risk elderly) were kept in the final equation. Higher age (Odds Ratio=0.92; 95% CI 0.86–0.98) and high cardiovascular risk elderly (OR=2.99; 95% CI 1.36–6.59) were associated to depression. Conclusions The present findings corroborate the different cognitive performance of elderly with high cardiovascular risk factors and the association of depressive symptoms with this group.

Full Text Available Goats are important in the livestock economy by their adaptability to adverse environmental conditions as they are good sources of protein and income for the rural poor. Studies conducted on the bacterial flora of the respiratory tract in goats focused on the pneumonic lungs, with fewer studies on the apparently normal nasal passage and antibiogram of isolated organisms. This study was carried out on 60 apparently healthy West African Dwarf goats. The nasal swab from each goat was analyzed using standard methods. The disc diffusion technique was used for the antibiotic sensitivity test. Three hundred and twenty-eight isolates were obtained. The most frequently isolated species was Streptococcus spp., while Escherichia coli and Staphylococcus aureus were the second dominant bacteria. Other species were isolated at relatively lower rates. The isolation of Mannheimia haemolytica and Pasteurella multocida from the nasal cavity of apparently healthy goats in this study reflects their possible role in most common respiratory diseases encountered in small ruminants. Most of the bacteria were found to be susceptible to streptomycin, quinolones (perfloxacin, ciprofloxacin and ofloxacin and gentamicin, while they were resistant to tetracycline, augmentin and erythromycin. This study shows the relationship between misuse or unrestricted use of antibiotics and drug resistance. Therefore, there is a need for practitioners and researchers to be informed of the appropriate antibiotics to be used in respiratory infections and during control programs.

To identify resources of the municipality of Sopó-Cundinamarca, Colombia, that are also opportunities to strengthen the development of an educational strategy that promotes healthy habits (healthy diet and exercise) as part of the comprehensive management of hypertension in the elderly. A qualitative study of a participatory-action research initiative in the Community Day Center of Sopó in the second semester of 2015. It was developed in three stages: first, a community diagnosis showed the need to integrate the culture, traditions and resources of the municipality as inputs that allow the adherence of healthy styles by the elderly for the control of hypertension; in the second stage, a work plan was established based on actions provided by the community; and in the third stage, we reflected on the results. An effective and sustainable intervention for the elderly can be achieved through the following activities: appropriation of the agricultural resources, the strengthening of dance as a form of exercise, use of motivational strategies, support of institutions that work with the welfare of the elderly, and the empowerment of facilitators. Interventions aimed at supporting the adherence of healthy lifestyles to the elderly should include and preserve the context of the community of which they are part, where community resources are the inputs that allow health promotion.

Total serum alpha 1-acid glycoprotein (AGP) concentration and concanavalin A-dependent microheterogeneity were studied in 31 healthy elderly subjects (18 men, 13 women, 71 to 76 yr old). Crossed affino-immunoelectrophoresis (CAIE) revealed three microheterogeneity variants of AGP: non-reactive, weakly reactive and strongly reactive with ConA. Two patterns were found in both elderly men and women, i.e. a normal pattern and one with an increase in the non-reactive form. Mean serum AGP levels in the elderly subjects with slightly higher than in a reference group of younger subjects. The Con A non-reactive form of AGP was increased in 42% of the elderly population. An increase in the non-reactive form of AGP in CAIE should be considered as general expression of chronic inflammation which is of no clinical relevance.

The effects of 24 wk of resistance training combined with a healthy diet on lower limb explosive strength capacity were investigated in a population of healthy elderly women. Participants ( n = 63; 67.5 ± 0.4 yr) were randomized into three groups; resistance training (RT), resistance training and healthy diet (RT-HD), and control (CON). Progressive resistance training was performed at a load of 75-85% one-repetition maximum. A major adjustment in the healthy dietary approach was an n-6/n-3 polyunsaturated fatty acid (PUFA) ratio below 2. Lower limb maximal strength, explosive force capacity during dynamic and isometric movements, whole body lean mass, and physical function were assessed. Whole body lean mass significantly increased by 1.5 ± 0.5% in RT-HD only. Isometric strength performance during knee extension as well as the performance in the five sit-to-stand and single-leg-stance tests increased similarly in RT and RT-HD. Improvements in dynamic peak power and time to reach peak power (i.e shorter time) during knee extension occurred in both RT (+15.7 ± 2.6 and -11.0 ± 3.8%, respectively) and RT-HD (+24.6 ± 2.6 and -20.3 ± 2.7%, respectively); however, changes were significantly larger in RT-HD. Similarly, changes in peak force and rate of force development during squat jump were higher in RT-HD (+58.5 ± 8.4 and +185.4 ± 32.9%, respectively) compared with RT (+35.7 ± 6.9 and +105.4 ± 22.4%, respectively). In conclusion, a healthy diet rich in n-3 PUFA can optimize the effects of resistance training on dynamic explosive strength capacity during isolated lower limb movements and multijoint exercises in healthy elderly women. NEW & NOTEWORTHY Age-related decline in lower limb explosive strength leads to impaired ability to perform daily living tasks. The present randomized controlled trial demonstrates that a healthy diet rich in n-3 polyunsaturated fatty acid (n-3 PUFA) enhances resistance training-induced gains in dynamic explosive strength

Full Text Available OBJECTIVE: Chronic low-grade inflammation and adipokines dysregulation are linked to mechanisms underscoring the pathogenesis of obesity-related metabolic disorders. Little is known about roles of these cytokines on the association between snoring and metabolic syndrome (MetS. We aimed to investigate whether a cluster of cytokines are related to snoring frequency and its association with MetS in apparently healthy Chinese. METHODS: Current analyses used a population-based sample including 1059 Shanghai residents aged 35-54 years. Self-reported snoring frequency was classified as never, occasionally and regularly. Fasting plasma glucose, lipid profile, insulin, C-reactive protein, interleukin-6, interleukin-18, lipopolysaccharide binding protein, high-molecular-weight adiponectin and leptin were measured. MetS was defined by the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian-Americans. RESULTS: Overweight/obese subjects had significantly higher prevalence of regular snorers than their normal-weight counterparts (34.8% vs. 11.5%, P<0.001. Regular snoring was associated with unfavorable profile of inflammatory markers and adipokines. However, those associations were abolished after adjustment for body mass index (BMI or waist circumference. The MetS risk (multivariate-adjusted odds ratio 5.41, 95% confidence interval 3.72-7.88 was substantially higher in regular snorers compared with non-snorers. Controlling for BMI remarkably attenuated the association (2.03, 1.26-3.26, while adjusting for inflammatory markers and adipokines showed little effects. CONCLUSION: Frequent snoring was associated with an elevated MetS risk independent of lifestyle factors, adiposity, inflammatory markers and adipokines in apparently healthy Chinese. Whether snoring pattern is an economic and no-invasive indicator for screening high-risk persons needs to be addressed prospectively.

The purpose of this study was to identify a method for assessing physical fitness age that is easy to use with both frail and healthy elderly women and to examine its validity. Principal component analysis was used to develop a formula of physical fitness age from four motor function variables. The subjects comprised 688 (75.7±6.0 years) elderly women, in order to develop a physical fitness scale. The formula for calculating physical fitness age was expressed as physical fitness age =-0.419× grip strength -0.096× balancing on one leg with eyes open -0.737×30 s chair stand +0.503× figure-of-8 walking test +0.47× chronological age +52.68. Measures obtained from subjects in the frail elderly (n=11, 73.0±2.3 years) and exercise (n=10, 70.8±3.1 years) groups were used to examine the validity of the assessment. The mean physical fitness age of the frail elderly group (79.0±3.7 years) was significantly higher than its mean chronological age (73.0±2.3 years, p fitness age of the exercise group (65.6±3.1 years) was significantly lower than the chronological age (70.8±3.1 years, p fitness age scores are applicable to frail and healthy elderly women. Physical fitness age is a valid measure of motor function in elderly women.

To determine how aging affects the impact of sleep deprivation on blood pressure at rest and under orthostatic challenge. Subjects underwent a night of sleep and 24.5 h of sleep deprivation in a crossover counterbalanced design. Sleep laboratory. Sixteen healthy normotensive men and women: 8 young adults (mean 24 years [SD 3.1], range 20-28 years) and 8 elderly adults (mean 64.1 years [SD 3.4], range 60-69 years). Sleep deprivation. Brachial cuff arterial blood pressure and heart rate were measured in semi-recumbent and upright positions. These measurements were compared across homeostatic sleep pressure conditions and age groups. Sleep deprivation induced a significant increase in systolic and diastolic blood pressure in elderly but not young adults. Moreover, sleep deprivation attenuated the systolic blood pressure orthostatic response in both age groups. Our results suggest that sleep deprivation alters the regulatory mechanisms of blood pressure and might increase the risk of hypertension in healthy normotensive elderly.

Performance on tasks that require saccadic inhibition declines with age and altered inhibitory functioning has also been reported in patients with Alzheimer's disease. Although mild cognitive impairment (MCI) is assumed to be a high-risk factor for conversion to AD, little is known about changes in saccadic inhibition and its neural correlates in this condition. Our study determined whether the neural activation associated with saccadic inhibition is altered in persons with amnestic mild cognitive impairment (aMCI). Functional magnetic resonance imaging (fMRI) revealed decreased activation in parietal lobe in healthy elderly persons compared to young persons and decreased activation in frontal eye fields in aMCI patients compared to healthy elderly persons during the execution of anti-saccades. These results illustrate that the decline in inhibitory functions is associated with impaired frontal activation in aMCI. This alteration in function might reflect early manifestations of AD and provide new insights in the neural activation changes that occur in pathological ageing. PMID:23898312

Aging is generally accompanied by changes in body composition, muscle mass and strength, leading to a decline in motor and functional performance. Physical activity and eating habits could be involved in modulating this paraphysiological deterioration. Aim of our study was to investigate changes in body composition, diet and physical performance in healthy, elderly females over a 3-year follow-up. 92 healthy elderly females (70.9±4.0 years) attending a twice-weekly mild fitness program were eligible for the study. They were assessed at baseline and again after 3 years in terms of clinical history, diet, body composition by DEXA, resting energy expenditure, handgrip strength, knee extensor isometric/isotonic strength, and functional performance measured using the Short Physical Performance Battery (SPPB). After 3 years, women had a significant decline in muscle strength (∆ isotonic: -1.4±4.3 kg, ∆ isokinetic: -2.0±6.3 kg, ∆ handgrip: -3.2±5.0 kg; pmeter walking time (r: 0.34; p<0.01). With advancing age, physical performance declines even in healthy, fit females despite a spare of weight and body composition. This decline in physical activity could lead to a lower calorie intake, which would explain why there is no variation in body weight. Copyright © 2012 Elsevier Inc. All rights reserved.

Full Text Available Global population is aging, particularly in developed countries and cities. Through the “Friendly Elderly Cities” and “Aging in Place” initiatives, various countries are making great efforts to improve the welfare and quality of life of the elderly, with the aim of catering to the physical and spiritual health as well as social welfare of the elderly. In this regard, the improvement of the housing environment of the elderly is one of the key factors in their quality of life and health. This study aims to effectively assess and improve the housing environment of the elderly in order to enhance their quality of life; it also aims to contribute the knowledge about improving elderly housing by applying an assessment framework using expert interviews and data collected from relevant literature. Using a mixed Multi-Criteria Decision Analysis model, a combination of the DEMATEL (Decision Making Trial and Evaluation Laboratory-based ANP (Analytic Network Process (DANP and the modified VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR methods, and the investigations and assessments in the case study, this study proposes strategies and directions for improving elderly housing. The study results indicate that, as distinct from using traditional methodologies where the hypothesis criteria are mutually independent, the proposed hybrid model (examining real-life problems by considering the mutual influences of factors identifies a priority sequence wherein emphasis is placed on improving ventilation and air quality rather than adjustment of temperature. The systemic way of thinking shifts the focus from the most apparent problems to the root cause of the problems. Doing so avoids any mismatch of resource allocation in decision-making and thus maximizes the efficiency and sustainability of the improvement.

Force plate is considered gold standard tool to assess body balance. However the Wii Balance Board (WBB) platform is a trustworthy equipment to assess stabilometric components in young people. Thus, we aim to examine the reliability of measures of center of pressure with WBB in healthy elderly women. Twenty one healthy and physically active women were enrolled in the study (age: 64 ± 7 years; body mass index: 29 ± 5 kg/m2. The WBB was used to assess the center of pressure measures in the individuals. Pressure was linearly applied to different points to test the platform precision. Three assessments were performed, with two of them being held on the same day at a 5- to 10-minute interval, and the third one was performed 48 h later. A linear regression analysis was used to find out linearity, while the intraclass correlation coefficient was used to assess reliability. The platform precision was adequate (R2 = 0.997, P = 0.01). Center of pressure measures showed an excellent reliability (all intraclass correlation coefficient values were > 0.90; p < 0.01). The WBB is a precise and reliable tool of body stability quantitative measure in healthy active elderly women and its use should be encouraged in clinical settings.

Full Text Available Background: Vitamin D which is involved in the maintenance of bone mineral homeostasis has been found to portray various pleiotropic effects. Although it has been widely accepted that serum 25-hydroxy Vitamin D level above 30 ng/ml is considered optimal for the biological actions of Vitamin D, there is a need to explore the levels of Vitamin D reported among Indians from various regions of the country. Hence, this systematic review aims to appraise the status of Vitamin D levels reported from apparently healthy Indians across various parts of India. Methodology: A comprehensive literature search was carried out to identify the range of Vitamin D levels among apparently healthy individuals from various parts of India, with the search term “Vitamin D and India” in the search portals of PubMed, Google Scholar, Indmed, and ScienceDirect. A total of 2998 articles were retrieved by the above search strategy, of which only forty studies fulfilled the criteria to be included in the systematic review. Studies done in various states were compiled under the respective zones based on the classification of Indian zones as specified in Zonal maps of India. Results: The level of Vitamin D from all the forty included studies ranged from 3.15 ± 1.4 to 52.9 ± 33.7 ng/ml. The effect size of Vitamin D level was higher in the South Zone compared to other zones. Conclusion: The present study shows that Vitamin D deficiency is prevalent among apparently healthy Indians living in different regions of India, irrespective of their exposure to sunlight.

The purpose of the present study was to examine the ability of the Contextual Memory Test (CMT) to differentiate between elderly people suffering from Alzheimer's disease (AD) in comparison to healthy elderly people. Specifically, the objectives were to compare for differences between and within the groups on components of memory, including immediate and delayed recall as well as recognition. In addition, parameters of metamemory skills, such as general awareness, self-prediction of memory capacity, self-estimation, strategy use and use of contextual information, as well as the correlation between self-awareness and actual performance in both groups, were investigated. The sample consisted of 60 elderly participants, including 30 people diagnosed with AD who were assigned to the research group and 30 people matched for age, gender and educational level who were assigned to the control group. The results provide support for the hypothesis positing differences in memory performance between healthy elderly participants and those suffering from AD, particularly in immediate and delayed recall as well as in recognition. Moreover, findings indicate an improvement in memory performance under the cued condition (contextual), whereas improvement in the AD group proved to be significant only for immediate recall. The findings point to a distinct overestimation of memory ability predicted by both the AD and control groups. Following the memory task, however, the participants accurately estimated the number of items they remembered. In addition, significant correlations between the use of contextual and association strategies and the number of items remembered by both groups were obtained, in immediate as well as in delayed recall. Therefore, these findings support the CMT as a valuable memory and metamemory assessment tool for use with the AD population.

The biggest challenge regarding cognitive prospective evaluations in the elderly is the identification of subjects that go on to develop cognitive impairment. In this study, we compared the Italian telephone version of the MMSE (Itel-MMSE) with both the MMSE and a battery of neuropsychological tests in a group of 107 healthy elderly subjects. The aim of the study was to identify a subset of subjects who, despite having an overall score within the normal range, performed poorly in the cognitive neuropsychological evaluation. The Itel-MMSE score showed a good internal consistency as well as a significant correlation with the MMSE score, age and education. A score of < or = 21 on the Itel-MMSE was the score which reflected the highest degree of sensitivity in the neuropsychological tests. There was a statistically significant difference between subjects with an Itel-MMSE score of < or = 21 and those with a score of 22 in age, education, Attentional Matrices and Copying Drawings. Despite some potential limitations, our results strongly suggest that the Itel-MMSE may be used as a screening test to identify healthy elderly subjects whose cognitive performance is poor.

To assess the BMI, life-style, and healthy status, and explore relationships between these parameters, among Menorca's free living elderly people. A cross-sectional survey carried out in Menorca Island in 2009. A random sample (n=450) of the elderly population (≥65 years) was interviewed. Anthropometric measurements and a general questionnaire incorporating questions related to socio-demographic and life-style factors and health status were used. Approximately five per cent of elders were underweight and 60% overweight or obese. Underweight were positively and overweight and obesity negatively affected by age. The prevalence of central obesity, according to the WC cut-off points, was 66.8% in men and 85.1% in women. Low education, socioeconomic status and physical activity were risk factors for malnutrition and overweight/obesity. A possible cognitive impairment was found among elderly persons with BMIrelation between BMI and diabetes mellitus, arthritis, and chronic bronchitis, and an inverted J-shape between BMI and gastric ulcer, osteoporosis and bone fractures, cancer, and prostatitis (in men) were found. Both low and high BMI are associated with a wide range of prevalent conditions and diseases in Menorca elderly men and women.

Full Text Available Abstract Memory loss is a major complaint among the elderly population. However, the clinical significance of this symptom is variable and also controversial in the scientific literature. Objective: To compare the cognitive performance of two groups of healthy elderly, one group with and the other without, subjective memory complaints (SMC. Methods: Sixty cognitively intact elderly individuals (39 females and 21 males, aged 69.9±6.3 years and with educational level of 8.5±5.5 years, were included in the study. Participants were submitted to the Mini-Mental State Examination and to the Cornell depression scale in order to rule out global cognitive impairment and depression, respectively. Moreover, they answered the MAC-Q, a questionnaire devised to evaluate subjective impression of memory function. Subsequently, they were submitted to the digit span forward and backward, the Brief Cognitive Screening Battery, and to the Frontal Assessment Battery. Results: Twenty-seven individuals had MAC-Q scores <25 and thus were classified as not having SMC, while 33 had MAC-Q scores ³25 and were considered to have SMC. No differences for age, gender, education and MMSE scores were found between the two groups. The comparison between the performance of the groups of complainers and non-complainers on the different cognitive tests yielded no significant difference, although there was a trend toward non-complainers performing better on incidental memory. Conclusions: The presence of SMC was not associated to objective memory impairment or to other cognitive deficits in this group of elderly individuals.

Gastrointestinal tract and the elderly: functional foods, gut microflora and healthy ageing.

Saunier, K; Doré, J

Advances in science and medicine as well as improved living standards have led to a steady increase in life expectancy. Yet ageing is associated with increased susceptibility to degenerative or infectious diseases, which may be exacerbated by a poor nutritional status. The intestinal microflora will mediate crucial events towards the protection or degradation of health. It is hence essential and timely that strategies of preventive nutrition aimed at maintaining or improving the quality of life of the ageing population be developed. "CROWNALIFE" is a newly funded EuropeanUnion project, so called because of its emphasis on the preservation of the period of independence of the elderly, recognised as the "crown of life". The project aims at assessing age-related alterations and exploring strategies to restore and maintain a balanced healthy intestinal environment. Current knowledge on the composition and function of the human intestinal microflora is still improving with the use of better methodologies and yet their evolution with ageing has not been investigated in detail. There have been a few reports that putatively protective lactic acid bacteria, in general, and bifidobacteria, in particular, seem less represented in the elderly faecal flora. We have also observed an increase in species diversity of the dominant faecal microflora with ageing. This certainly warrants confirmation and is being addressed by the investigation of age-related changes in the structure and function of the intestinal flora of the elderly in countries across Europe. Ensuing results will constitute a baseline for functional-food based strategies aimed at providing health benefits for the elderly.

Methods A total of 115 healthy subjects without known cardiovascular risk factors or overt heart disease who underwent both transthoracic echocardiography and brachial-ankle pulse wave velocity (baPWV measurement at the same day during their routine check-ups were analyzed. Results The mean age of study subjects was 52.8 ± 8.4 years, and 78 (67.8% were men. The mean baPWV value was 1,325 ± 185 cm/s. Study subjects were divided into 3 groups according to E/E’ value: subjects with E/E’ p β = 0.371, p after controlling confounders including age, sex and body mass index. In receiver-operating characteristic (ROC curve analysis, the sensitivity and specificity for detection of E/E’ ≥ 10 were 78.6% and 59.8%, respectively with mean baPWV of 1,282 cm/s as the cut off value. The discriminatory capacity for predicting E/E’ ≥ 10 was improved from an area under the ROC curve of 0.646 with age alone to 0.734 when baPWV was added (p Conclusions There is a significant association between baPWV and E/E’ in an apparently healthy Korean population. BaPWV is useful as a simple and non-invasive method for early detection of increased LV filling pressure among these people.

To identify dietary, environmental and socio-economic factors associated with mild zinc deficiency, three zinc status indices; erythrocyte membrane zinc (RBCMZn), plasma zinc and super oxide dismutase (SOD) were assessed in free living and apparently healthy Indian population. Dietary patterns of 232 men and 223 women (20-65 yr) from rural, industrial and urban regions of Western India were evaluated by food frequency questionnaire. RBCMZn was estimated using atomic absorption spectrometry, hemoglobin and serum ceruloplasmin by spectrophotometer. On a sub sample (48 men and 51 women) plasma zinc and SOD were also assessed. Mean RBCMZn was 0.5 +/- 0.1 micromols/g protein with 46% individuals showing zinc deficiency. Mean plasma zinc was 0.98 +/- 0.12 microg/mL with 25% men and 2.5% women having values below normal range. Mean SOD was 0.97 +/- 0.1 (u/mL cells). A significant positive correlation was observed between intakes of green leafy vegetables, other vegetables and milk products with RBCMZn status (p plasma zinc (p > 0.2). Cereal and legume intakes were negatively correlated with RBCMZn (p plasma zinc (p 0.2). Fruit and other vegetable intake were positively correlated with SOD (p Plasma zinc indicated positive association with zinc, thiamin and riboflavin intakes (p plasma zinc and SOD. Prominent determinants of zinc status were intakes of beta-carotene and zinc along with environmental conditions and family size.

Full Text Available Objectives: The present study aimed to assess elderly “healthy eating diet” -2005 (HED-2005 quality and its relationship to their socio-demographic variables in healthy subjects aged 60 years and over who live in the urban areas of Iran`s Markazi province. Methods & Materials: This study was a descriptive-analytic survey that included 165 elderly in the urban areas of Iran`s Markazi province. Data were obtained via a general questionnaire and three 24-hours recalls. Results: The mean of overall HEI-2005 was 54.08. Ninty-three point three percent (93.3% of subjects consumed grains, 70.9% fruits, 84.2% whole fruit, 47.9% vegetables, 12.7% dark-orange vegetables and legumes, 37% dairy products, 40% meats, 18.8% oils, 40% saturated fats, 1.8% sodium and 1.2% discretionary calories (from solid fat and added sugar in optimal levels. Besides, none of the elderly people had a sufficient intake of whole grains. The HEI-2005 total score enhanced along with the increases in education level (P<0.05, income (P<0.01 and TV watching time (P<0.05. But, age and the HEI-2005 total score had an inverse relationship (P<0.001. Conclusion: Because the diet quality of elderly people in the urban areas of Iran`s Markazi province is low, they will benefit from the improvement of their diet quality. Also, they need to increase intakes of whole grains, dark-orange vegetables and legumes and plant oils, and reduce intakes of sodium and their energy levels from saturated fat and simple sugar. It should be pointed out that the government can help with the achievement of these objectives through some plans such as promoting their literacy level, income and nutritional knowledge.

2015-01-01

Full Text Available Background: Psychomotor retardation (PR is one of the core features in depression according to 17 DSM V1, but also aging in itself causes cognitive and psychomotor slowing. This is the first study 18 investigating psychomotor retardation in relation to cognitive functioning and to the concomitant 19 effect of depression and aging in a geriatric population ruling out contending effects of psychotropic 20 medication. Methods: A group of 28 non-demented depressed elderly is compared to a matched 21 control group of 20 healthy elderly. All participants underwent a test battery containing clinical 22 depression measures, cognitive measures of processing speed, executive function and memory, 23 clinical ratings of psychomotor retardation and objective computerized fine motor skill-tests. 24 Statistical analysis consisted of a General Linear Method (GLM multivariate analysis of variance to 25 compare the clinical, cognitive and psychomotor outcomes of the two groups. Results: Patients 26 performed worse on all clinical, cognitive and psychomotor retardation measures. Both groups 27 showed an effect of cognitive load on fine motor function but the influence was significantly larger 28 for patients than for healthy elderly except for the initiation time. Limitations: due to the restrictive 29 inclusion criteria, only a relatively limited sample size could be obtained. Conclusion: With a 30 medication free sample, an additive effect of depression and aging on cognition and PR in geriatric 31 patients was found,. As this effect was independent of demand of effort (by varying the cognitive 32 load, it was apparently not a motivational slowing effect of depression.

SUVN-502, a selective 5-HT6 receptor antagonist, was found to be active in preclinical models of cognitive deterioration suggesting a potential role in the treatment of dementia related to Alzheimer's disease. The objective of this study was to characterize the safety, tolerability and pharmacokinetics of SUVN-502 in healthy young adults and elderly subjects following single and multiple oral doses. Single doses (5, 15, 50, 100 and 200 mg SUVN-502) and multiple doses (50, 100 and 130 mg SUVN-502 once daily for 7 days) were evaluated in healthy young adults and multiple doses (50 and 100 mg SUVN-502 once daily for 14 days) were evaluated in elderly subjects using randomized, double-blind, placebo-controlled, dose-escalating study designs. The effect of food, gender and age on SUVN-502 pharmacokinetics (100 mg single dose) was evaluated using an open-label, two-period, randomized, fed and fasted in a crossover design. SUVN-502 and M1 (major metabolite of SUVN-502) were monitored using validated analytical methods. SUVN-502 is safe and well tolerated up to the highest tested single dose of 200 mg in healthy young adults and multiple doses up to 130 mg for 7 days and 100 mg for 14 days in healthy young adults and elderly subjects, respectively. Exposures of SUVN-502 and M1 were more than dose-proportional over the evaluated dose range. Food and gender did not have a clinically meaningful effect on SUVN-502 exposure. The mean SUVN-502 total (AUC 0-∞ , and AUC 0-last ) and peak exposures (C max ) were 2.9- and 2.2-fold higher, respectively, in elderly subjects compared to young subjects. Steady-state was achieved for SUVN-502 and M1 within 7 days after once-daily dosing of SUVN-502. SUVN-502 exhibited an acceptable safety, tolerability and pharmacokinetic profile in healthy young adults and elderly subjects. Based on the above results, 50 and 100 mg once-daily doses of SUVN-502 were advanced to Phase 2 evaluation in patients with moderate AD.

The proportion of European elderly is expected to increase to 30% in 2060. Combining dietary components may modulate many processes involved in ageing. So, it is likely that a healthful diet approach might have greater favourable impact on age-related decline than individual dietary components. This paper describes the design of a healthful diet intervention on inflammageing and its consequences in the elderly. The NU-AGE study is a parallel randomized one-year trial in 1250 apparently healthy, independently living European participants aged 65-80 years. Participants are randomised into either the diet group or control group. Participants in the diet group received dietary advice aimed at meeting the nutritional requirements of the ageing population. Special attention was paid to nutrients that may be inadequate or limiting in diets of elderly, such as vitamin D, vitamin B12, and calcium. C-reactive protein is measured as primary outcome. The NU-AGE study is the first dietary intervention investigating the effect of a healthful diet providing targeted nutritional recommendations for optimal health and quality of life in apparently healthy European elderly. Results of this intervention will provide evidence on the effect of a healthful diet on the prevention of age related decline. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Objective: Early detection of Chronic Obstructive Pulmonary Disease in apparently healthy attendants of tertiary care hospital and assessment of its severity. Study Design: Cross-sectional, observational study. Place and Duration of Study: Study was conducted from January 2015 to July 2015 at Dow University Hospital, Ojha campus. Methodology: A screening method was designed for apparently healthy individuals including attendants of patients, hospital staff, faculty and students, belonging to age group 18-60 years after excluding severe obesity and already diagnosed respiratory and cardiovascular diseases by means of history. Each participant performed pulmonary function tests via spirometer after filling a questionnaire based on various risk factors and symptoms of chronic obstructive pulmonary disease (COPD). Data was entered and analysed by SPSS-20. Results: Out of the 517 participants, 122 (23.6%) were found to have COPD diagnosed by means of spirometry. Out of these, 23 (4.4%) had COPD stage I, 42 (8.1%) had COPD II, 34 (6.6%) had COPD III, and 23 (4.4%) had COPD IV. Exposure to smoking, wooden stoves, pesticides, biomass fuel, aerosol sprays, gas grill and vehicle exhaust were found to be statistically significant factors in relation to development of COPD. Conclusion: Apparently healthy individuals may have underlying COPD and active screening by means of spirometry plays vital role in early detection of COPD. Smoking and exposure to certain hazardous environmental pollutants are responsible for the development and progression of COPD. (author)

Many countries encounter a demographic change where the number of elderly people will increase. As a result, the number of very old people needing care, services and medical assistance will increase. Care in the private home is often described as providing the best alternative for many elderly people. The aim of this study was to describe elderly people's perceptions of how they wanted to be cared for, from a perspective of becoming in need of assistance with personal care, in the future. Twelve couples of healthy elderly people living in a couple hood participated in an interview study. They were all 70 years and older and received no kind of professional care or social support. Open individual semi-structured interviews were conducted with the support of written vignettes. The vignettes were formed as scenarios that described three levels of caring needs where the elderly people would become ill. A qualitative content analysis was used to analyse the interviews. The findings were interpreted in one main theme: maintaining the self and being cared for with dignity to the end. The theme was built from three categories: at home as long as possible, professional care at nursing home when advanced care is needed and fear of being abandoned. The categories reflect the perception that when minimum help was needed, care and support by the partner and nursing staff were preferred. As the scenarios changed to being totally dependent on care, they preferred care in a nursing home. There was a pervading concern of the risk of not being seen as an individual person and becoming a nobody with no meaningful relations. Thus, there must be a singular goal to support old people, in all stages of their lives, through the recognition and affirmation of self, and providing care with dignity to the end.

We conducted a prospective study with a subjective assessment form for high-speed digital imaging (HSDI) to elucidate the features of vocal fold vibrations in vocally healthy subjects and to clarify gender- and age-related differences. Healthy adult volunteers participated in this study. They were divided into young (aged 35 and younger) and elderly (aged 65 and older) groups, and the scores of an assessment form for HSDI characteristics elaborated at our institution were statistically analyzed. Twenty-six young subjects (males: 9, females: 17; mean age: 27 years) and 20 elderly subjects (males: 8, females: 12; mean age: 72 years) were assigned to our study. Posterior gap and posterior-to-anterior longitudinal phase difference were characteristic to young females, whereas in young males, mucosal wave, anterior-to-posterior longitudinal phase difference, and supraglottic hyperactivity were frequent. In elderly males, axis shift, asymmetry, supraglottic hyperactivity, increased mucosal wave, lateral phase difference, and anterior-to-posterior longitudinal phase difference were frequent; and in elderly females, high incidence of lateral phase difference, atrophic change, anterior gap, and asymmetry were observed. The results show that the behaviors of vocal fold vibrations were diverse even in healthy subjects with no vocal complaints or history of laryngeal diseases, and hence, the diversity of vocal fold vibrations in normal subjects must be taken into account in evaluating vocal fold vibrations.

Pedersen, Maria; Bruunsgaard, Helle; Weis, Nina

2003-01-01

The purpose of the current study was to test the hypothesis that an altered fat distribution in elderly healthy subjects and in patients with type-2 diabetes contributes to high circulating levels of interleukin (IL)-6 and tumor necrotic factor (TNF)-alpha, which secondly is related to lower muscle...... mass. Twenty young controls, (20-35 yr), 20 healthy elderly subjects (65-80 yr) and 16 elderly patients with type 2 diabetes (65-80 yr) were included in a cross sectional study. Plasma levels of TNF-alpha and IL-6 were measured after an overnight fast. Dual-energy X-ray absorptiometry and total body...... potassium counting measured truncal fat, appendicular skeletal muscle mass (ASM) and body cell mass (BCM), respectively. TNF-alpha, IL-6 and the relative truncal fat mass were higher in elderly compared with young controls. ASM was lower in diabetic men than in young controls and BCM was lower in elderly...

2014-01-01

The health of older people is a priority in many countries as the world's population ages. Attitudes towards help seeking behaviours in older people remain a largely unexplored field of research. This is particularly true for older minority groups where the place that they have migrated to presents both cultural and structural challenges. The UK, like other countries, has an increasingly aging Chinese population about who relatively little is known. This study used a qualitative grounded theory design following the approach of Glaser (1978). Qualitative data were collected using semi-structured interviews with 33 Chinese elders who were aged between 60 and 84, using purposive and theoretical sampling approaches. Data were analysed using the constant comparative method until data saturation occurred and a substantive theory was generated. "Being healthy" (the core category) with four interrelated categories: self-management, normalizing/minimizing, access to health services, and being cured form the theory. The theory was generated around the core explanations provided by participants and Chinese elders' concerns about health issues they face in their daily life. We also present data about how they direct their health-related activities towards meeting their physical and psychological goals of being healthy. Their differential understanding of diseases and a lack of information about health services were potent predictors of non-help seeking and "self" rather than medical management of their illnesses. This study highlights the need for intervention and health support for Chinese elders.

Full Text Available BackgroundWe investigated the association of coronary artery calcium score (CACS with body composition and insulin resistance in apparently healthy Korean adults.MethodsNine hundred forty-five participants (mean age, 48.9 years; 628 men in a medical check-up program were selected for analysis. Body composition was assessed by bioelectrical impedance analysis (BIA. Insulin resistance was evaluated using the homeostasis model assessment of insulin resistance (HOMA-IR. The CACS was assessed by multidetector computed tomography.ResultsOne hundred forty-six subjects (15.4% showed coronary artery calcification and 148 subjects (15.7% had metabolic syndrome. CACS showed a significant positive correlation with age, fasting glucose level, waist circumference (WC, blood pressure, hemoglobin A1c, HOMA-IR, and waist-hip ratio (WHR assessed by BIA. CACS had a negative correlation with high density lipoprotein cholesterol (HDL-C. Subjects with high CACS showed significantly higher mean WHRs and lower mean values for lean body mass compared with subjects without coronary artery calcification. In logistic regression analyses with coronary artery calcification as the dependent variable, the highest quartile of WHR showed a 3.125-fold increased odds ratio for coronary artery calcification compared with the lowest quartile after adjustment for confounding variables. When receiver operating characteristics analyses were performed with coronary artery calcification as the result variable, WHR showed the largest area under the curve (AUC value among other variables except for age and WC in women (AUC=0.696 for WHR, 0.790 for age, and 0.719 for WC in women.ConclusionIn our study population of apparently healthy Korean adults, WHR was the most significant predictor for coronary artery calcification among other confounding factors, suggesting that it may have implication as a marker for early atherosclerosis.

Previous studies have demonstrated a positive association between obesity and decreased lung function. However, the effect of muscle and fat has not been fully assessed, especially in a healthy elderly population. In this study, we evaluated the impact of low muscle mass (LMM) and LMM with obesity on pulmonary impairment in healthy elderly subjects. Our study used data from the Korea National Health and Nutrition Examination Survey from 2008 to 2011. Men and women aged 65 yr or older were included. Muscle mass was measured by dual-energy X-ray absorptiometry. LMM was defined as two standard deviations below the sex-specific mean for young healthy adults. Obesity was defined as body mass index ≥ 25 kg/m(2). The prevalence of LMM in individuals aged over 65 was 11.9%. LMM and pulmonary function (forced vital capacity and forced expiratory volume in 1 second) were independently associated after adjusting for age, sex, body mass index, smoking status, alcohol consumption, and frequency of exercise. LMM with obesity was also related to a decrease in pulmonary function. This study revealed that LMM is an independent risk factor of decreased pulmonary function in healthy Korean men and women over 65 yr of age.

Full Text Available Nursing care for the elderly should aim to promote elderly health and reduction of foreseeable risk factors, as well as value and institute measures to the greatest possible degree of autonomy and independence in the elderly in relation to his life and especially about his Cheers. With this view, we carried out a study with 16 members aged from Linkages Strengthening Group of a Social Assistance Reference Center (CRAS, the municipality of Sinop - MT, to enhance understanding of the elderly as the promotion of health through education about risk and protective factors of the most common diseases and health problems among the elderly. We used the action research as a methodological reasons, because this means turning the subject both at the level of thought and in action. The results of this research showed a female predominance in the participation of older age groups, increased participation of older widows with education of 01 years to 04 years. The perception of the elderly as the educational activity performed was satisfactory, reporting that the dynamics of the talks were good, important and promoted new information. It was also found through most of the elderly respondents reported the need for health education activities for this audience. It is concluded that the elderly incorporated into their daily health promotion measures learned in the educational activity, with improvements in quality of life. As well, the need to implement more health education programs for the elderly aimed at promoting healthy aging.

Full Text Available Abstract Background There is strong evidence that an individual's genetic background is an important predisposing factor to longevity. In the present study we analysed the frequency of HLA class I, class II, as well as the TNF-α -308 polymorphism that may be related to an increased life span in Mexican Mestizo healthy elders. Results HLA typing was performed by polymerase chain reaction sequence specific oligonucleotide (PCR SSO reverse dot blot. The TNF-α -308 polymorphism was assessed by PCR restriction fragment length polymorphism. A significant increased frequency of HLA-DRB1*11 was found in elderly women whereas this allele was not present in elderly males. The TNF2 allele was also increased in the elder group when compared to young controls. The frequencies of the remaining alleles tested were not statistically different among groups. Conclusion These data suggest an ethnicity independent tendency of HLA-DRB1*11 in elder females to increase life span and a possible role of the TNF2 allele with the successful remodelling of senescent immune system.

To analyze the effect of education on sentence listening comprehension on cognitively healthy elderly. A total of 111 healthy elderly, aged 60-80 years of both genders were divided into two groups according to educational level: low education (0-8 years of formal education) and high education (≥9 years of formal education). The participants were assessed using the Revised Token Test, an instrument that supports the evaluation of auditory comprehension of orders with different working memory and syntactic complexity demands. The indicators used for performance analysis were the number of correct responses (accuracy analysis) and task execution time (temporal analysis) in the different blocks. The low educated group had a lower number of correct responses than the high educated group on all blocks of the test. In the temporal analysis, participants with low education had longer execution time for commands on the first four blocks related to working memory. However, the two groups had similar execution time for blocks more related to syntactic comprehension. Education influenced sentence listening comprehension on elderly. Temporal analysis allowed to infer over the relationship between comprehension and other cognitive abilities, and to observe that the low educated elderly did not use effective compensation strategies to improve their performances on the task. Therefore, low educational level, associated with aging, may potentialize the risks for language decline.

Cognitive decline in aging is a pressing issue associated with significant healthcare costs and deterioration in quality of life. Previously, we reported the successful use of a novel brain-computer interface (BCI) training system in improving symptoms of attention deficit hyperactivity disorder. Here, we examine the feasibility of the BCI system with a new game that incorporates memory training in improving memory and attention in a pilot sample of healthy elderly. This study investigates the safety, usability and acceptability of our BCI system to elderly, and obtains an efficacy estimate to warrant a phase III trial. Thirty-one healthy elderly were randomized into intervention (n = 15) and waitlist control arms (n = 16). Intervention consisted of an 8-week training comprising 24 half-hour sessions. A usability and acceptability questionnaire was administered at the end of training. Safety was investigated by querying users about adverse events after every session. Efficacy of the system was measured by the change of total score from the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) before and after training. Feedback on the usability and acceptability questionnaire was positive. No adverse events were reported for all participants across all sessions. Though the median difference in the RBANS change scores between arms was not statistically significant, an effect size of 0.6SD was obtained, which reflects potential clinical utility according to Simon's randomized phase II trial design. Pooled data from both arms also showed that the median change in total scores pre and post-training was statistically significant (Mdn = 4.0; pattention (p = 0.039), and delayed memory (pattention in healthy elderly, and appears to be safe, user-friendly and acceptable to senior users. Given the efficacy signal, a phase III trial is warranted. ClinicalTrials.gov NCT01661894.

To determine the effect of age on cardiovascular performance, 39 healthy elderly men and women, 70 to 83 years old, underwent treadmill thallium-201 exercise perfusion imaging and radionuclide equilibrium angiography at rest and during supine bicycle exercise. Five volunteers who had a positive exercise thallium test response were excluded from the study. Radionuclide left ventricular ejection fraction, regional wall abnormalities, relative cardiac output, stroke volume, end-diastolic volume and end-systolic volume were measured. Seventy-four percent of the subjects maintained or increased their ejection fraction with exercise. With peak exercise, mean end-diastolic volume did not change, end-systolic volume decreased and cardiac output and stroke volume increased. Moreover, in 35% of the subjects, minor regional wall motion abnormalities developed during exercise. There was no significant difference in the response of men and women with regard to these variables. However, more women than men had difficulty performing bicycle ergometry because they had never bicycled before. Subjects who walked daily performed the exercise tests with less anxiety and with a smaller increase in heart rate and systolic blood pressure

Escitalopram is the (S)-enantiomer of citalopram that has a potential QT prolonging effect. In this study, 12 healthy elderly individuals received a single oral dose of escitalopram (20 mg), and their pharmacokinetics and QT effect data were compared with data from 33 younger adults obtained in a previous study. Serial blood samples for pharmacokinetic analysis were collected and ECG was performed up to 48 h postdose. The elderly and younger adults showed similar pharmacokinetic profiles. The geometric mean ratios (90% confidence interval) of the elderly compared with the younger adults were 1.02 (0.89-1.17) and 1.01 (0.86-1.17) for the maximum plasma concentration and area under the concentration-time curve, respectively. The mean baseline-adjusted QT (dQT) time profiles were similar and the mean values of maximum dQT were not significantly different between the elderly and the younger adults. The linear mixed-effect model indicated a weak but positive relationship between the escitalopram concentration and dQT, with an estimated coefficient of concentration of 0.43-0.54. In conclusion, the pharmacokinetics and QT effect of a single dose of escitalopram observed in the elderly without comorbidities and younger adults were generally similar.

Aging is associated with dramatic reductions in sleep continuity and sleep intensity. Since gaboxadol, a selective GABA(A) receptor agonist, has been demonstrated to improve sleep consolidation and promote deep sleep, it may be an effective hypnotic, particularly for elderly patients with insomnia. In the present study, we investigated the effects of subchronic gaboxadol administration on nocturnal sleep and its residual effects during the next days in elderly subjects. This was a randomized, double-blind, placebo-controlled, balanced crossover study in 10 healthy elderly subjects without sleep complaints. The subjects were administered either placebo or 15 mg gaboxadol hydrochloride at bedtime on three consecutive nights. Sleep was recorded during each night from 2300 to 0700 h and tests assessing attention (target detection, stroop test) and memory function (visual form recognition, immediate word recall, digit span) were applied at 0900, 1400, and 1700 h during the following days. Compared with placebo, gaboxadol significantly shortened subjective sleep onset latency and increased self-rated sleep intensity and quality. Polysomnographic recordings showed that it significantly decreased the number of awakenings, the amount of intermittent wakefulness, and stage 1, and increased slow wave sleep and stage 2. These effects were stable over the three nights. None of the subjects reported side effects. Next-day cognitive performance was not affected by gaboxadol. Gaboxadol persistently improved subjective and objective sleep quality and was devoid of residual effects. Thus, at the employed dose, it seems an effective hypnotic in elderly subjects.

Backward descent of stairs is associated with improved muscle strength and reduced joint stress, but the effect of backward ascent of stairs on lower limb muscle strength has not been reported. This study compared the effects of forward and backward stair climbing on lower limb muscle strength in apparently healthy young adults. Methods. The total of 31 young volunteers were allocated to either forward or backward stair climbing group (n = 16 and 15, respectively. Dynamic quadriceps and hamstring muscle strength was assessed in addition to thigh girth at baseline and at weeks 4 and 8 with the use of the repetitive maximum method and tape measure, respectively. Results. Between baseline and week 8, muscular strength in both groups (quadriceps: 14.4 ± 3.6 to 16.4 ± 3.4 kg; 14.0 ± 2.9 to 15.3 ± 2.7 kg; hamstring: 12.2 ± 3.2 to 13.4 ± 3.2; 11.7 ± 2.5 to 12.9 ± 2.7 kg increased significantly (p 0.05. The groups were comparable in all three measures post intervention. Conclusions. Forward and backward stair climbing protocols are effective for improving the dynamic strength of the hamstring and quadriceps muscles of apparently healthy young adults. Thus, either protocol could be used for the improvement of lower limbs dynamic muscle strength.

Full Text Available Cognitive reserve (CR helps explain the mismatch between expected cognitive decline and observed maintenance of cognitive functioning in older age. Factors such as education, literacy, lifestyle, and social networking are usually considered to be proxies of CR and its variability between individuals. A more direct approach to examine CR is through the assessment of capacity to gain from practice in a standardized challenging cognitive task that demands activation of cognitive resources. In this study, we applied a testing-the-limits paradigm to a group of 136 healthy elderly subjects (60–75 years and additionally examined the possible contribution of complex mental activities and quality of sleep to cognitive performance gain. We found a significant but variable gain and identified verbal memory, cognitive flexibility, and problem-solving as significant factors. This outcome is in line with our earlier study on CR in healthy mental aging. Interestingly and contrary to expectations, our analysis revealed that complex mental activities and sleep quality do not significantly influence CR. Contrasting “high” and “low” cognitive performers revealed significant differences in verbal memory and cognitive flexibility; again, complex mental activities and sleep quality did not contribute to this measure of CR. In conclusion, the results of this study support and extend previous findings on CR in older age; further, they underline the need for improvements in existing protocols for assessing CR in a dynamic manner.

Full Text Available The purpose of this systematic review is to assess the evidence behind the dietary requirement of protein and to assess the health effects of varying protein intake in healthy elderly persons in order to evaluate the evidence for an optimal protein intake. The literature search covered year 2000–2011. Prospective cohort, case–control, and intervention studies of a general healthy population in settings similar to the Nordic countries with protein intake from food-based sources were included. Out of a total of 301 abstracts, 152 full papers were identified as potentially relevant. After careful scrutiny, 23 papers were quality graded as A (highest, n=1, B (n=18, or C (n=4. The grade of evidence was classified as convincing, probable, suggestive, or inconclusive. The evidence is assessed as: probable for an estimated average requirement (EAR of 0.66 g good-quality protein/kg body weight (BW/day based on nitrogen balance (N-balance studies and the subsequent recommended dietary allowance (RDA of 0.83 g good-quality protein/kg BW/day representing the minimum dietary protein needs of virtually all healthy elderly persons. Regarding the optimal level of protein related to functional outcomes like maintenance of bone mass, muscle mass, and strength, as well as for morbidity and mortality, the evidence is ranging from suggestive to inconclusive. Results from particularly prospective cohort studies suggest a safe intake of up to at least 1.2–1.5 g protein/kg BW/day or approximately 15–20 E%. Overall, many of the included prospective cohort studies were difficult to fully evaluate since results mainly were obtained by food frequency questionnaires that were flawed by underreported intakes, although some studies were ‘calibrated’ to correct for under- or over-reporting. In conclusion, the evidence is assessed as probable regarding the EAR based on N-balance studies and suggestive to inconclusive regarding an optimal protein intake higher than

Full Text Available Cognitive decline in aging is a pressing issue associated with significant healthcare costs and deterioration in quality of life. Previously, we reported the successful use of a novel brain-computer interface (BCI training system in improving symptoms of attention deficit hyperactivity disorder. Here, we examine the feasibility of the BCI system with a new game that incorporates memory training in improving memory and attention in a pilot sample of healthy elderly. This study investigates the safety, usability and acceptability of our BCI system to elderly, and obtains an efficacy estimate to warrant a phase III trial. Thirty-one healthy elderly were randomized into intervention (n = 15 and waitlist control arms (n = 16. Intervention consisted of an 8-week training comprising 24 half-hour sessions. A usability and acceptability questionnaire was administered at the end of training. Safety was investigated by querying users about adverse events after every session. Efficacy of the system was measured by the change of total score from the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS before and after training. Feedback on the usability and acceptability questionnaire was positive. No adverse events were reported for all participants across all sessions. Though the median difference in the RBANS change scores between arms was not statistically significant, an effect size of 0.6SD was obtained, which reflects potential clinical utility according to Simon's randomized phase II trial design. Pooled data from both arms also showed that the median change in total scores pre and post-training was statistically significant (Mdn = 4.0; p<0.001. Specifically, there were significant improvements in immediate memory (p = 0.038, visuospatial/constructional (p = 0.014, attention (p = 0.039, and delayed memory (p<0.001 scores. Our BCI-based system shows promise in improving memory and attention in healthy

This study explores the applicability of a cognitive stimulation method based on abacus arithmetic in elderly people with and without cognitive impairment. This observational and prospective pilot study was performed in 2 hospitals. The study assessed the applicability of a programme of arithmetic training developed for use in the elderly population. The primary endpoint was an evaluation of the stimulation programme, in terms of usability, satisfaction, and participation, in healthy elderly controls and elderly patients with mild cognitive impairment or Alzheimer disease. Secondary endpoints were family satisfaction, caregiver burden, and the behaviour and cognition of patients. Usability, satisfaction, and degree of participation were high. The Mini-Mental State Examination showed significant changes (23.1±4.8 before the intervention vs 24.9±4.2 afterwards, P=.002); there were no changes on the Trail Making Test parts A and B, Yesavage Geriatric Depression scale, and Zarit caregiver burden scale. The study suggests that cognitive stimulation with abacus arithmetic may be used in elderly people with and without cognitive impairment. Further studies will be needed to evaluate the efficacy of this kind of programmes. Copyright © 2014 Sociedad Española de Neurología. Published by Elsevier España, S.L.U. All rights reserved.

There is growing evidence that cognitive training (CT) can improve the cognitive functioning of the elderly. CT may be influenced by cultural and linguistic factors, but research examining CT programs has mostly been conducted on Western populations. We have developed an innovative electroencephalography (EEG)-based brain-computer interface (BCI) CT program that has shown preliminary efficacy in improving cognition in 32 healthy English-speaking elderly adults in Singapore. In this second pilot trial, we examine the acceptability, safety, and preliminary efficacy of our BCI CT program in healthy Chinese-speaking Singaporean elderly. Thirty-nine elderly participants were randomized into intervention (n=21) and wait-list control (n=18) arms. Intervention consisted of 24 half-hour sessions with our BCI-based CT training system to be completed in 8 weeks; the control arm received the same intervention after an initial 8-week waiting period. At the end of the training, a usability and acceptability questionnaire was administered. Efficacy was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), which was translated and culturally adapted for the Chinese-speaking local population. Users were asked about any adverse events experienced after each session as a safety measure. The training was deemed easily usable and acceptable by senior users. The median difference in the change scores pre- and post-training of the modified RBANS total score was 8.0 (95% confidence interval [CI]: 0.0-16.0, P=0.042) higher in the intervention arm than waitlist control, while the mean difference was 9.0 (95% CI: 1.7-16.2, P=0.017). Ten (30.3%) participants reported a total of 16 adverse events - all of which were graded "mild" except for one graded "moderate". Our BCI training system shows potential in improving cognition in both English- and Chinese-speaking elderly, and deserves further evaluation in a Phase III trial. Overall, participants

Owing to excessive worries regarding adverse cardiac events, hyperthermal balneotherapy for patients with coronary artery disease is underprescribed. However, very few cardiac events occur in similar heat stress during Finnish sauna bathing. Exercise testing has proven to be a safe diagnostic procedure even in survivors of myocardial infarction. We compared the effects of hyperthermal immersion and exercise testing on cardiac hemodynamics in 21 apparently healthy women aged 50-60 years. The maximal symptom-limited bicycle exercise test was performed according to the modified protocol of Wasserman. Hyperthermal immersion was carried out in 40 degrees C water and was completed by increasing the core temperature by about 2 degrees C. The left ventricular function was evaluated using continuous measurement of thoracic electric bioimpedance during both tests. The blood pressure, index of contractility and heart rate were measured directly, whereas the cardiac index, left cardiac work index and systemic vascular resistance index were calculated. The hemodynamic response, as assessed at continuous non-invasive monitoring, showed substantial differences between hyperthermal immersion and exercise testing. Overall, we found a significantly lower hemodynamic load during hyperthermal immersion in comparison with exercise testing. Entering the bath, there was a significant decrease in the left cardiac work, contractility and blood pressure. We recorded a slight increase in the heart rate towards peak hyperthermal immersion. However, other modulators such as the mean arterial pressure, index of contractility, cardiac index and left cardiac work index decreased even below resting values. Excessive hyperthermal immersion induced a lower hemodynamic load in apparently healthy women than standard maximal exercise testing.

Full Text Available The purpose of this study was to demonstrate the potential alterations in structural network properties related to physical activity (PA in healthy elderly. We recruited 76 elderly individuals with normal cognition from Samsung Medical Center in Seoul, Korea. All participants underwent the Cambridge Neuropsychological Test Automated Battery and 3.0T brain magnetic resonance imaging (MRI. Participants were subdivided into quartiles according to the International Physical Activity Questionnaire scores, which represents the amount of PA. Through graph theory based analyses, we compared global and local network topologies according to PA quartile. The higher PA group demonstrated better performance in speed processing compared to the lower PA group. Regional nodal strength also significantly increased in the higher PA group, which involved the bilateral middle frontal, bilateral inferior parietal, right medial orbitofrontal, right superior and middle temporal gyri. These results were further replicated when the highest and the lowest quartile groups were compared in terms of regional nodal strengths and local efficiency. Our findings that the regional nodal strengths associated with the attentional network were increased in the higher PA group suggest the preventive effects of PA on age-related cognitive decline, especially in attention.

The present study investigated the association between postural tasks and center of pressure spatial patterns of three-dimensional statokinesigrams. Young (n=35; 27.0±7.7years) and elderly (n=38; 67.3±8.7years) healthy volunteers maintained an undisturbed standing position during postural tasks characterized by combined sensory (vision/no vision) and biomechanical challenges (feet apart/together). A method for the analysis of three-dimensional statokinesigrams based on nonparametric statistics and image-processing analysis was employed. Four patterns of spatial distribution were derived from ankle and hip strategies according to the quantity (single; double; multi) and location (anteroposterior; mediolateral) of high-density regions on three-dimensional statokinesigrams. Significant associations between postural task and spatial pattern were observed (young: gamma=0.548, p<.001; elderly: gamma=0.582, p<.001). Robustness analysis revealed small changes related to parameter choices for histogram processing. MANOVA revealed multivariate main effects for postural task [Wilks' Lambda=0.245, p<.001] and age [Wilks' Lambda=0.308, p<.001], with interaction [Wilks' Lambda=0.732, p<.001]. The quantity of high-density regions was positively correlated to stabilogram and statokinesigram variables (p<.05 or lower). In conclusion, postural tasks are associated with center of pressure spatial patterns and are similar in young and elderly healthy volunteers. Single-centered patterns reflected more stable postural conditions and were more frequent with complete visual input and a wide base of support. Copyright © 2013 Elsevier B.V. All rights reserved.

The maximum isometric force production capacity of the fingers decreases with age. However, little information is available on age-related changes in dynamic motor capacity of individual fingers. The purpose of this study was to compare the dynamic motor function of individual fingers between elderly and young adults using rapid single-finger and double-finger tapping. Fourteen elderly and 14 young adults performed maximum frequency tapping by the index, middle, ring, or little finger (single-finger tapping) and with alternate movements of the index-middle, middle-ring, or ring-little finger-pair (double-finger tapping). The maximum pinch force between the thumb and each finger, tactile sensitivity of each fingertip, and time taken to complete a pegboard test were also measured. Compared with young subjects, the older subjects had significantly slower tapping rates in all fingers and finger-pairs in the tapping tasks. The age-related decline was also observed in the tactile sensitivities of all fingers and in the pegboard test. However, there was no group difference in the pinch force of any finger. The tapping rate of each finger did not correlate with the pinch force or tactile sensitivity for the corresponding finger in the elderly subjects. Maximum rate of finger tapping was lower in the elderly adults compared with the young adults. The decline of finger tapping ability in elderly adults seems to be less affected by their maximum force production capacities of the fingers as well as tactile sensitivities at the tips of the fingers.

[Purpose] Balance is an integral part of human ability. The smart balance master system (SBM) is a balance test instrument with good reliability and validity, but it is expensive. Therefore, we modified a Wii Fit balance board, which is a convenient balance assessment tool, and analyzed its reliability and validity. [Subjects and Methods] We recruited 20 healthy young adults and 20 elderly people, and administered 3 balance tests. The correlation coefficient and intraclass correlation of both instruments were analyzed. [Results] There were no statistically significant differences in the 3 tests between the Wii Fit balance board and the SBM. The Wii Fit balance board had a good intraclass correlation (0.86-0.99) for the elderly people and positive correlations (r = 0.58-0.86) with the SBM. [Conclusions] The Wii Fit balance board is a balance assessment tool with good reliability and high validity for elderly people, and we recommend it as an alternative tool for assessing balance ability.

Self-regulation refers to the successful use of executive functions and initiation of top-down processes to control one's thoughts, behavior, and emotions, and it is crucial to perform self-control. Self-control is needed to overcome impulses and can be assessed by delay of gratification (DoG) and delay discounting (DD) paradigms. In children/adolescents, good DoG/DD ability depends on the maturity of frontostriatal connectivity, and its decline in strength with advancing age might adversely affect self-control because prefrontal brain regions are more prone to normal age-related atrophy than other regions. Here, we aimed at highlighting the relationship between frontostriatal connectivity strength and DoG performance in advanced age. We recruited 40 healthy elderly individuals (mean age 74.0 ± 7.7 years) and assessed the DoG ability using the German version of the DoG test for adults in addition to the delay discounting (DD) paradigm. Based on diffusion-weighted and resting-state functional magnetic resonance imaging data, respectively, the structural and functional whole-brain connectome were reconstructed based on 90 different brain regions of interest in addition to a 12-node frontostriatal DoG-specific network and the resulting connectivity matrices were subjected to network-based statistics. The 90-nodes whole-brain connectome analyses revealed subnetworks significantly associated with DoG and DD with a preponderance of frontostriatal nodes involved suggesting a high specificity of the findings. Structural and functional connectivity strengths between the putamen, caudate nucleus, and nucleus accumbens on the one hand and orbitofrontal, dorsal, and ventral lateral prefrontal cortices on the other hand showed strong positive correlations with DoG and negative correlations with DD corrected for age, sex, intracranial volume, and head motion parameters. These associations cannot be explained by differences in impulsivity and executive functioning. This pattern

Cardiovascular diseases are the leading cause of death and disability in the elderly. In this study, healthy eating habits and associated factors in the prevention of cardiovascular disease in elderly hypertensive individuals were identified. It involved a cross-sectional study gathering primary data in a family health unit in a city in the interior of the state of Rio Grande do Sul and 212 elderly hypertensive individuals participated in the study. A higher prevalence among the lower age bracket of elderly individuals, female, with little schooling and low income was revealed. Healthy eating habits among the elderly hypertensive individuals assessed are below those recommended in the prevention of cardiovascular disease. Social and economic factors, health characteristics and the use of health services influenced the adoption of healthy eating habits. The results of this study suggest that elderly hypertensive individuals find it difficult to adopt healthy eating habits. This contributes further to the definition of strategies for routine prevention and control of cardiovascular diseases in the elderly.

The aim of this study was to assess the immunomodulatory effect of KC-1317 (a symbiotic mixture containing Saccharomyces boulardii lysate in a cranberry, colostrum-derived lactoferrin, fragaria, and lactose mixture) supplementation in immune-compromised but otherwise healthy elderly subjects. A liquid formulation of KC-1317 was administered in a randomized controlled trial (RCT) fashion to healthy volunteers (65-79 years) previously selected for low natural killer (NK) cell activity, and this parameter was checked at the completion of the study. A significant improvement in NK cell activity of KC-1317 consumers was observed as compared to placebo at the end of 2 months. Although preliminary, these beneficial immune-modulatory effects of KC-1317 in aged individuals might indicate its employment within a wider age-management strategy.

Personality traits are generally known to be stable, although the brain changes with aging. Especially women experience striking alterations in the neuroendocrinergic system at menopause, which may cause considerable changes in personality traits and alter their underlying neural substrates. To investigate changes in the neural substrates underlying personality traits, we investigated metabolic correlates of personality traits in women before and after menopause. We obtained FDG PET images from 13 young (24.0±3.1 y) and 11 elderly females (66.8±3.3 y). Three factors of personality traits (novelty seeking (NS), harm avoidance (HA), reward dependence (RD)) were assessed using Cloninger's 240-item Temperament and Characteristic Inventory. Three ANCOVA maps were created in SPM2 (P < 0.01 uncorrected, k = 100), each constructed to assess the metabolic correlates of each temperament factor. In young females NS scores were negatively correlated with glucose metabolism in the right insula and right cingulate; in elderly females, the right cuneus. In young females HA scores were positively correlated with glucose metabolism in the right lingual gyrus; in elderly females, the left anterior cingulate and bilateral hippocampus. Only in elderly females, HA scores were negatively correlated with glucose metabolism in the right orbital gyrus and bilateral frontal gyri. In young females, RD scores were positively correlated with glucose metabolism in the bilateral frontal gyri and bilateral cingulate; in elderly females, the right middle frontal gyrus. In young females, RD scores were negatively correlated with glucose metabolism in the right precuneus; in elderly females, the left insula. We found that neural substrates underlying personality traits in females were dissociable across young and elderly women. These results may provide better understanding of differential prevalence and susceptibility to psychiatric illnesses in young and elderly females

In young females, RD scores were negatively correlated with glucose metabolism in the right precuneus; in elderly females, the left insula. We found that neural substrates underlying personality traits in females were dissociable across young and elderly women. These results may provide better understanding of differential prevalence and susceptibility to psychiatric illnesses in young and elderly females.

The serotonin 2A (5-HT{sub 2A}) receptor is of interest in several psychiatric and neurological diseases. In the present study we investigated the longitudinal stability of 5-HT{sub 2A} receptors and the stability of the quantification procedure in the elderly in order to be able to study elderly patients with neuropsychiatric diseases on a longitudinal basis. [{sup 18}F]-Altanserin PET was used to quantify 5-HT{sub 2A} receptors in 12 healthy elderly individuals at baseline and at 2 years in six volumes of interest. A bolus/infusion protocol was used to achieve the binding potential, BP{sub P}. The reproducibility as assessed in terms of variability and the reliability as assessed in terms of intraclass correlation coefficient (ICC) were used to compare inter- and intraobserver stability and to evaluate the effects of increasing complexity of partial volume (PV) corrections. We also compared the stability of our measurements over 2 years with the stability of data from an earlier study with 2-week test-retest measurements. BP{sub P} was unaltered at follow-up without the use of PV correction and when applying two-tissue PV correction, test-retest reproducibility was 12-15% and reliability 0.45-0.67 in the large bilateral regions such as the parietal, temporal, occipital and frontal cortices, while orbitofrontal and anterior cingulate cortical regions were less stable. The use of PV correction decreased the variability but also decreased the between-subject variation, thereby worsening the reliability. In healthy elderly individuals, brain 5-HT{sub 2A} receptor binding remains stable over 2 years, and acceptable reproducibility and reliability in larger regions and high intra- and interobserver stability allow the use of [{sup 18}F]-altanserin in longitudinal studies of patients with neuropsychiatric disorders.

Obesity and non-insulin dependent diabetes mellitus (NIDDM) are common in the Third Age and increasing in Cuba. Among the life-style changes associated with increased prevalence of obesity and its related disorders, diet and activity patterns are prime candidates. The transition to this life-style model may induce a decrease in the energy needs. There is an urgent need for tools which have been validated for measuring diet and physical activity in nutritional studies in the developing world, but also a more urgent need for reference values for the total energy requirements of healthy elderly people. Regular physical activity reduces the likelihood to develop diseases that characterise the metabolic cardiovascular syndrome. Previous studies done in Havana showed values of physical activity level (PAL) which are lower than the reported for elderly subjects. Elderly people living in rural areas use to have physical activity levels which differ from the observed in urban areas. With the purpose of estimating the energy requirements, a group of 40 apparently healthy people older than 60 years of age living in a rural mountain community will be submitted to a medical, epidemiological, dietary, anthropometric and insulin resistance study. Physical activity will be determined by questionnaire and by the calculation of the PAL from the basal metabolic rate (BMR) and total energy expenditure (TEE) measured with the doubly-labelled water method (DLW). Associations with the prevalence of insulin resistance and obesity will be assessed. (author)

Aging is associated with decreased growth hormone (GH) secretion and plasma insulin-like growth factor-I (IGF-I) levels, increased total and abdominal fat, total and low-density lipoprotein (LDL) cholesterol, and triglycerides, and reduced high-density lipoprotein (HDL) cholesterol. Similar changes in lipids and body composition occur in nonelderly GH-deficient adults and are reversed with GH administration. To examine whether GH/IGF-I axis function in the elderly is related to the lipid profile independently of body fat, we evaluated GH secretion, serum IGF-I and IGF binding protein-3 (IGFBP-3) levels, adiposity via the body mass index (BMI), waist to hip ratio (WHR), dual-energy x-ray absorptiometry (DEXA), and magnetic resonance imaging (MRI), and circulating lipids in 101 healthy subjects older than 65 years. Integrated nocturnal GH secretion (log IAUPGH) was inversely related (P HDL cholesterol (P HDL cholesterol was inversely related to the WHR (P body fat, to be an independent determinant of total (P HDL cholesterol (P HDL in women (P body fat or lipid measures, except for a positive correlation of IGF-I with triglycerides in men. Thus, endogenous nocturnal GH secretion predicts total, LDL, and HDL cholesterol levels independently of total or abdominal fat, suggesting that it is an independent cardiometabolic risk factor in healthy elderly people.

Disuse atrophy of swallowing-related organs due to an excessive decrease in swallowing frequency is suspected to occur in patients with poor oral intake, especially elderly people. However, swallowing frequency in daily life has not previously been examined in the elderly. This study examined swallowing frequency in elderly people and compared these findings to those in a younger population and differences in the degree of activity in daily life. (i) We compared swallowing frequency in 20 elderly people (82·0 ± 8·3 year) and 15 healthy young people (26·5 ± 3·5 year). (ii) 20 elderly people were divided into two groups according to the degree of activity in daily life: a semi-bedridden group and bedridden group; the swallowing frequency was compared between these groups. (i) The swallowing frequency in the elderly people was 2-19 times per hour and the mean was 9·4 ± 4·9, and that in the healthy young people was 16-76 times per hour and the mean was 40·7 ± 19·5. Swallowing frequency in elderly people was significantly lower than that in young healthy people (P bedridden group was 2-11 times per hour and the mean was 6·8 ± 3·3, and that in semi-bedridden group was 3-19 times per hour and the mean was 11·9 ± 5·1. Swallowing frequency in bedridden group was significantly lower than that in semi-bedridden group (P elderly people tend to swallow less frequently than young people. In addition, swallowing frequency was lower in elderly subjects with a low degree of activity in daily life. © 2013 John Wiley & Sons Ltd.

Resting state brain activity incorporates different components, including the Default Mode Network and the Dorsal Attention Network, also known as task-negative network and task-positive network respectively. These two networks typically show an anticorrelated activity during both spontaneous oscillations and task execution. However modifications of this anticorrelated activity pattern with age and pathology are still unclear. The present study aimed to investigate differences in resting state Default Mode Network-Dorsal Attention Network functional anticorrelation among young adults, healthy elders and Mild Cognitive Impairment patients. We retrospectively enrolled in this study 27 healthy young adults (age range: 25-35 y.o.; mean age: 28,5), 26 healthy elders (age range: 61-72 y.o.; mean age: 65,1) and 17 MCI patients (age range 64-87 y.o.; mean age: 73,6). Mild Cognitive Impairment patients were selected following Petersen criteria. All participants underwent neuropsychological evaluation and resting state functional Magnetic Resonance Imaging. Spontaneous anticorrelated activity between Default Mode Network and Dorsal Attention Network was observed in each group. This anticorrelation was significantly decreased with age in most Default Mode Network-Dorsal Attention Network connections (p Default Mode Network and the right inferior parietal sulcus node of the Dorsal Attention Network was significantly decreased when comparing Mild Cognitive Impairment with normal elders (p Default Mode Network and Dorsal Attention Network is part of the normal aging process and that Mild Cognitive Impairment status is associated with more evident inter-networks functional connectivity changes.

Advanced age is associated with changes in body composition such as muscular mass loss, which is defined as sarcopenia. The former term plays a key role in the frailty model, although its source is unknown. Myriad strategies have been used to improve and increase muscular mass and function in older persons. The muscle is a versatile system that owes its great capacity to adaption to regular exercise programs. Aerobic exercise and resistance training improve muscular function and can minimize and even reverse sarcopenia in the elderly (healthy, very elderly or frail). The main difference in prescribing exercise for healthy adults and elderly individuals is that intensity of training program is lower for the latter. This review is aimed toward the physiopathologic aspects and clinical implications regarding muscular mass loss and to programs directed toward increasing strength and/or endurance in the elderly.

Passive heat induces beneficial perfusion profiles, provides substantive cardiovascular strain, and reduces blood pressure, thereby holding potential for healthy and cardiovascular disease populations. The aim of this study was to assess acute responses to passive heat via lower-limb, hot-water immersion in patients with peripheral arterial disease (PAD) and healthy, elderly controls. Eleven patients with PAD (age 71 ± 6 yr, 7 male, 4 female) and 10 controls (age 72 ± 7 yr, 8 male, 2 female) underwent hot-water immersion (30-min waist-level immersion in 42.1 ± 0.6°C water). Before, during, and following immersion, brachial and popliteal artery diameter, blood flow, and shear stress were assessed using duplex ultrasound. Lower-limb perfusion was measured also using venous occlusion plethysmography and near-infrared spectroscopy. During immersion, shear rate increased ( P Lower-limb blood flow increased significantly in both groups, as measured from duplex ultrasound (>200%), plethysmography (>100%), and spectroscopy, while central and peripheral pulse-wave velocity decreased in both groups. Mean arterial blood pressure was reduced by 22 ± 9 mmHg (main effect P lower 3 h afterward. In PAD, popliteal shear profiles and claudication both compared favorably with those measured immediately following symptom-limited walking. A 30-min hot-water immersion is a practical means of delivering heat therapy to PAD patients and healthy, elderly individuals to induce appreciable systemic (chronotropic and blood pressure lowering) and hemodynamic (upper and lower-limb perfusion and shear rate increases) responses.

Full Text Available BackgroundCognitive decline is characteristic for Alzheimer’s disease (AD and also for healthy ageing. As a proof-of-concept study, we examined whether this decline can be counteracted using real-time fMRI neurofeedback training. Visuospatial memory and the parahippocampal gyrus (PHG were targeted.MethodsSixteen healthy elderly subjects (mean age 63.5 years, SD = 6.663 and 10 patients with prodromal AD (mean age 66.2 years, SD = 8.930 completed the experiment. Four additional healthy subjects formed a sham-feedback condition to validate the paradigm. The protocol spanned five examination days (T1–T5. T1 contained a neuropsychological pre-test, the encoding of a real-world footpath, and an anatomical MRI scan of the brain. T2–T4 included the fMRI neurofeedback training paradigm, in which subjects learned to enhance activation of the left PHG while recalling the path encoded on T1. At T5, the neuropsychological post-test and another anatomical MRI brain scan were performed. The neuropsychological battery included the Montreal Cognitive Assessment (MoCA; the Visual and Verbal Memory Test (VVM; subtests of the Wechsler Memory Scale (WMS; the Visual Patterns Test; and Trail Making Tests (TMT A and B.ResultsHealthy elderly and patients with prodromal AD showed improved visuospatial memory performance after neurofeedback training. Healthy subjects also performed better in a working-memory task (WMS backward digit-span and in the MoCA.

However, Granger-causality-analysis revealed changes in cerebral connectivity over the course of the training, involving the parahippocampus and identifying the precuneus as main driver of activation in both groups. Voxel-based morphometry showed increases in grey matter volumes in the precuneus and frontal cortex. Neither cognitive

Full Text Available The aim of this study was to determine the correlation between subclinical deficiency of Vit A, Vit C and zinc and ovine pneumonia. This study was conducted on 400 sheep affected by pneumonia and 100 apparently healthy sheep. All animals were from the Ghezel breed with the age of 0.5-2 years and body weight of 35-60 kg. Sampling was done during the summer and autumn in Miandoab province. Patients showing signs of rapid and shallow breathing, dyspnea, coughing, nasal discharge and abnormal lung sound were selected as having pneumonia. Animals without any sign of particular disease were selected as apparently healthy after general examination. Blood samples were collected from the jugular vein. The results indicated that serum levels of vitamin A, vitamin C and zinc were 46.94±0.26 (μg/dl, 1.83±0.05 (mg/dl and 183.25±1.86 (μg/dl in healthy sheep respectively and serum levels of vitamin A, vitamin C and zinc were 42.45±0.19 (μg/dl, 1.47±0.02 (mg/dl and 134.59±1.77 (μg/dl in pneumonic sheep (p=0.000 respectively.

Maximal and rapid torque characteristics of the hip extensor muscles play an important role in fall prevention and other balance-related performances; however, few studies have investigated the ability of these variables at identifying fall-history status in healthy, recreationally active elderly adults. This study aimed to examine the effectiveness of maximal and rapid isometric torque characteristics of the hip extensor muscles to differentiate between healthy, recreationally active elderly females with (fallers) and without (non-fallers) a history a falls. Six elderly female fallers (mean ± SD: age = 73 ± 7 year; mass = 68 ± 16 kg; height = 160 ± 5 cm) and nine elderly female non-fallers (age = 71 ± 7 year; mass = 66 ± 16 kg; height = 157 ± 6 cm) performed two isometric maximal voluntary contractions (MVCs) of the hip extensor muscles. Peak torque (PT) and absolute and relative rate of torque development (RTD) at the early (0-50 ms) and late (100-200 ms) phases of muscle contraction were examined during each MVC. Absolute and relative RTD at 0-50 ms were greater (P = 0.039 and 0.011, respectively) in the non-fallers compared to the fallers. However, no group-related differences (P = 0.160-0.573) were observed for PT nor absolute and relative RTD at 100-200 ms. Early rapid strength production of the hip extensor muscles may be a sensitive and effective measure for discriminating between elderly females of different fall histories. These findings may provide important insight regarding implications for the assessment of fall risk and in the development of proper training programs aimed at minimizing the occurrence of falls and other balance-related injuries in the elderly.

Bacterial pneumonia is a major cause of morbidity and mortality in elderly. We hypothesize that dysbiosis between regular residents of the upper respiratory tract (URT) microbiome, that is balance between commensals and potential pathogens, is involved in pathogen overgrowth and consequently disease. We compared oropharyngeal microbiota of elderly pneumonia patients (n=100) with healthy elderly (n=91) by 16S-rRNA-based sequencing and verified our findings in young adult pneumonia patients (n=27) and young healthy adults (n=187). Microbiota profiles differed significantly between elderly pneumonia patients and healthy elderly (PERMANOVA, P<0.0005). Highly similar differences were observed between microbiota profiles of young adult pneumonia patients and their healthy controls. Clustering resulted in 11 (sub)clusters including 95% (386/405) of samples. We observed three microbiota profiles strongly associated with pneumonia (P<0.05) and either dominated by lactobacilli (n=11), Rothia (n=51) or Streptococcus (pseudo)pneumoniae (n=42). In contrast, three other microbiota clusters (in total n=183) were correlated with health (P<0.05) and were all characterized by more diverse profiles containing higher abundances of especially Prevotella melaninogenica, Veillonella and Leptotrichia. For the remaining clusters (n=99), the association with health or disease was less clear. A decision tree model based on the relative abundance of five bacterial community members in URT microbiota showed high specificity of 95% and sensitivity of 84% (89% and 73%, respectively, after cross-validation) for differentiating pneumonia patients from healthy individuals. These results suggest that pneumonia in elderly and young adults is associated with dysbiosis of the URT microbiome with bacterial overgrowth of single species and absence of distinct anaerobic bacteria. Whether the observed microbiome changes are a cause or a consequence of the development of pneumonia or merely coincide with

Fifty-one elderly women (66.1±4.4 years, apparently healthy, insufficiently active, and without prior experience in RT were randomly assigned into two groups: Training Group (TG = 24 and Control Group (CG = 27. The TG was submitted to a standardized RT program composed of eight exercises, performed in two sets of 10 to 15 repetitions, three times a week, and the CG was submitted to a 12 week stretching exercise program composed by two sessions per week of 30 minutes each. Their physical and functional fitness level was analyzed before and after the intervention period by motor testing to assess Right and Left Upper Limb Endurance (RULE, LULE, Lower Limb Endurance (LLE, Flexibility (FLEX, Manual Skills (MS, Ability to Put on Socks (APS, and Coordination (COORD. The TG had improved performance in LLE (+13.8%, RULE (+24.3%, LULE (+22.9%, and MS (- 0.9 s, whereas the CG improved performance in RULE (+13.9% and LULE (+14.1%, but had increased time in COORD by (+1.5 s, and these were the only tests showing significant interactions of group vs. time (p<0.05. The results suggest that 12 weeks of RT seem to be sufficient to induce positive changes on physical and functional fitness of healthy and previously untrained elderly women.

Full Text Available BackgroundSeveral studies have suggested that elevated levels of hemoglobin A1c (HbA1c are associated with cardiovascular disease (CVD in nondiabetic individuals. However, it is unclear whether HbA1c levels can serve as a simple screening marker for increased CVD risk in nondiabetic individuals. Our objective was to evaluate the relationship between HbA1c levels and CVD risk using the Framingham risk score (FRS in older, apparently healthy nondiabetic Korean adults.MethodsWe retrospectively studied 2,879 Korean adults between the ages of 40 and 79 who underwent voluntary health check-ups at the Health Promotion Center of our hospital from July 2009 to June 2011. Subjects were subdivided based on their HbA1c levels into four groups: tertiles within the HbA1c normal tolerance range and a group for subjects with an increased risk for diabetes (IRD.ResultsThe mean FRS for the upper tertile (9.6±3.8 group was significantly higher than that of the middle tertile (8.4±4.0 and lower tertile (7.6±3.8 groups. In addition, FRS was highest in the IRD group (10.5±3.7. Multiple linear regression analysis demonstrated that HbA1c levels exhibited a significant positive correlation with FRS when adjusted for confounding variables in all subjects (β±standard error [SE], 0.018±0.002; R2, 0.131, women (β±SE, 0.023±0.003; R2, 0.170, and men (β±SE, 0.016±0.004; R2, 0.109.ConclusionHbA1c levels were positively correlated with FRS in older, apparently healthy nondiabetic Korean adults. We propose that HbA1c levels may reflect CVD risk in nondiabetic individuals.

Increased thoracic kyphosis is one of the most disfiguring consequences of osteoporotic spine fractures in the elderly. However, mechanisms involved in the increasing of the kyphosis degree among osteoporotic women are not completely understood. Then, the aims of this cross-sectional preliminary study were comparing thoracic kyphosis degree, trunk muscle peak torque and joint position sense among healthy and osteoporotic elderly women and investigating possible factors affecting the kyphosis degree. Twenty women were selected for 2 groups: healthy (n=10) and osteoporotic (n=10) elderly women. Bone mineral density (BMD), thoracic kyphosis degree, trunk muscles peak torque and joint position sense were measured. Differences among groups were analyzed by Student's Test T for unpaired data. Correlations between variables were performed by Pearson's coefficient correlation. The level of significance used for all comparisons was 5% (p≤0.05). We observed that the osteoporotic women demonstrated a significantly higher degree of kyphosis and lower trunk extensor muscle peak torque. Moreover, it was found that the BMD had a negative correlation with the thoracic kyphosis degree. Kyphosis degree showed a negative correlation between extensor muscle strength and joint position sense index. This study suggests that lower BMD may be associated to higher degree of kyphosis degree, lower trunk extensors muscle strength and an impaired joint position sense. It is also suggested that lower extensor muscle strength may be a factor that contributes to the increasing in kyphosis thoracic degree. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Deficits in cognition have been reported in Parkinson's disease (PD) already in the early and even in the pre-motor stages. Whilst substantia nigra hyperechogenicity measured by transcranial B-mode sonography (TCS) represents a strong PD marker and is associated with an increased risk for PD in still healthy individuals, its association with cognitive performance in prodromal PD stages is not well established. Two different cohorts of healthy elderly individuals were assessed by TCS and two different neuropsychological test batteries covering executive functions, verbal memory, language, visuo-constructional function and attention. Cognitive performance was compared between individuals with hyperechogenicity (SN+) and without hyperechogenicity (SN-). In both cohorts, SN+ individuals performed significantly worse than the SN- group in tests assessing verbal memory (word list delayed recall P = 0.05, logical memory II P Color-Word Reading, P = 0.004) could only be shown in one of the two cohorts. No between-group effects were found in other cognitive tests and domains. These results indicate that individuals with the PD risk marker SN+ perform worse in verbal memory compared to SN- independent of the assessment battery. Memory performance should be assessed in detail in individuals at risk for PD. © 2016 EAN.

The purpose of this study was to determine the pathogens responsible for asymptomatic bacteriuria in elderly and middle-aged individuals in Alajue-Ede, South-Western Nigeria, and to identify any associated factors. Mid-stream urine samples were collected from apparently healthy elderly and middle-aged volunteers who were participating in community health screening. Samples were processed and bacterial isolates were identified following standard procedures. In total, 128 volunteers (48 men, 76 women participated in the study. Twenty-eight (22.6% urinary pathogens were isolated, comprising Klebsiella species in five (17.9%, Pseudomonas aeruginosa in one (3.6%, Escherichia coli in 19 (67.9%, and Proteus species in three (10.7% cases. Women were identified as being at higher risk of asymptomatic bacteriuria, and the prevalence also increased with increasing age in men. The elderly in this community have a high prevalence of asymptomatic bacteriuria, and screening for comorbid medical conditions may be of benefit.

Obesity and overweight are strongly associated with cardiovascular morbidity and mortality. However, there are limited data on the association between excess weight and the risk of ectopic ventricular activity. We investigated the association between body mass index (BMI) and the risk for ectopic ventricular activity (defined as multiple ventricular premature beats (≥3), ventricular bigeminy, nonsustained ventricular tachycardia or sustained ventricular tachycardia) during exercise stress testing among 22,516 apparently healthy men and women who attended periodic health screening examinations between the years 2000 and 2014. All subjects had completed maximal exercise stress testing annually according to the Bruce protocol. Subjects were divided at baseline into three groups: normal weight (BMI ≥ 18.5 kg/m(2) andexercise-induced ectopic ventricular activity arrhythmias was highest among obese subjects, intermediate among overweight subjects and lowest among subjects with normal weight (3.4%, 2.7% and 2.2% respectively; p exercise compared with subjects with normal weight (p = 0.005), and that each 1 kg/m(2) increase in BMI was associated with a significant 4% (p = 0.002) increased adjusted risk for exercise-induced ventricular arrhythmias. Obesity is independently associated with increased likelihood of ectopic ventricular arrhythmia during exercise. © The European Society of Cardiology 2015.

Programs focused on active aging do not always have actions to guide the elderly about healthy eating. Therefore, the concordance between the feeding habits and the morphological characteristics of this population group is little known. To correlate the anthropometric health indexes with the frequency of food consumption in physically active elderly (PAE). The sample consisted of 307 physically active Chilean elders of both sexes (8.4% males), with a mean age of 70.2 years. The studied variables corresponded to nutritional status, abdominal adiposity, cardiovascular risk and frequency of food consumption. A logistic regression model was applied, considering alpha active Chilean elderly who exhibit less healthy eating behavior.

Ageing in western society has become a key issue in political and academic debate: politicians, sociologists, doctors, demographers, psychologists, economists are trying to understand how ageing will impact our future society. In this frame, media and communication technologies seem to be more and more relevant for the elderly, thanks to those services and devices helping people to grow old actively. Technologies, the Internet and ICTs could help the elderly to improve their quality of life, to be healthy and independent and to get better assistance. Our ongoing research investigates the relationship between the elderly and use of technologies, and explores the role played by media and ICTs in building a friendly and positive environment for the elderly, and in constructing and maintaining social relations and promoting healthy ageing. Specifically, the research will investigate the use of ICTs by the elderly by taking into account two different perspectives: a) Exchanges between generations: lengthening of life corresponds to a longer period of cohabitation between at least three generations (grandparents, children, grandchildren), and also of co-use of digital media. The research wants to investigate relations between two age groups (grandparents and grandchildren; young people and older people) to understand the dynamics of intergenerational mutuality in the use of technologies and ICTs. b) Media, ICTs, Health: the Western world is increasingly populated by elderly population. Technologies and ICTs can help elderly people to improve their quality of life, to be healthy and independent and to get better assistance. ICTs should encourage active ageing and, in the case of health technologies, new models of care. The project, lasting 1 year, is based on (1) a survey on young elderly (65-74 yrs) population in Italy, and (2) a field-work which consists of family interviews and ethnographical sections in natural contexts.

Reliability of System Identification Techniques to Assess Standing Balance in Healthy Elderly.

Full Text Available System identification techniques have the potential to assess the contribution of the underlying systems involved in standing balance by applying well-known disturbances. We investigated the reliability of standing balance parameters obtained with multivariate closed loop system identification techniques.In twelve healthy elderly balance tests were performed twice a day during three days. Body sway was measured during two minutes of standing with eyes closed and the Balance test Room (BalRoom was used to apply four disturbances simultaneously: two sensory disturbances, to the proprioceptive and the visual system, and two mechanical disturbances applied at the leg and trunk segment. Using system identification techniques, sensitivity functions of the sensory disturbances and the neuromuscular controller were estimated. Based on the generalizability theory (G theory, systematic errors and sources of variability were assessed using linear mixed models and reliability was assessed by computing indexes of dependability (ID, standard error of measurement (SEM and minimal detectable change (MDC.A systematic error was found between the first and second trial in the sensitivity functions. No systematic error was found in the neuromuscular controller and body sway. The reliability of 15 of 25 parameters and body sway were moderate to excellent when the results of two trials on three days were averaged. To reach an excellent reliability on one day in 7 out of 25 parameters, it was predicted that at least seven trials must be averaged.This study shows that system identification techniques are a promising method to assess the underlying systems involved in standing balance in elderly. However, most of the parameters do not appear to be reliable unless a large number of trials are collected across multiple days. To reach an excellent reliability in one third of the parameters, a training session for participants is needed and at least seven trials of two

Apparently healthy preschool children (46 boys, 52 girls) aged 27-50 mo from low socioeconomic conditions who attended daycare centers in Santiago participated in a 14-mo long double-blind zinc supplementation trial. Unlike most previous studies, no additional inclusion criteria such as short stature or slow growth rate were considered. Subjects were pair matched according to sex and age and randomly assigned to two experimental groups: the supplemented group, which received 10 mg Zn/d, and the placebo group. Selected anthropometric, clinical, dietary, biochemical, and functional indexes were determined at the beginning of the study and after 6 and 14 mo of intervention. Actual dietary zinc intake was 66% of the recommended dietary allowance. Height gain after 14 mo was on average 0.5 cm higher in the supplemented group (P = 0.10). The response, however, was different between sexes. Boys from the supplemented group gained 0.9 cm more than those in the placebo group (P = 0.045). No effect was seen in girls. Although no significant differences were observed in the rest of the variables studied, trends (0.05 < P < 0.10) in the supplemented group compared with the placebo group for increased midarm muscle area in boys, improved response to tuberculin, and reduced rates of parasite reinfestation were noted. We conclude that in preschool children of low socioeconomic status, zinc is a limiting factor in the expression of growth potential.

Standing balance requires multijoint coordination between the ankles and hips. We investigated how humans adapt their multijoint coordination to adjust to various conditions and whether the adaptation differed between healthy young participants and healthy elderly. Balance was disturbed by push/pull rods, applying two continuous and independent force disturbances at the level of the hip and between the shoulder blades. In addition, external force fields were applied, represented by an external stiffness at the hip, either stabilizing or destabilizing the participants' balance. Multivariate closed-loop system-identification techniques were used to describe the neuromuscular control mechanisms by quantifying the corrective joint torques as a response to body sway, represented by frequency response functions (FRFs). Model fits on the FRFs resulted in an estimation of time delays, intrinsic stiffness, reflexive stiffness, and reflexive damping of both the ankle and hip joint. The elderly generated similar corrective joint torques but had reduced body sway compared with the young participants, corresponding to the increased FRF magnitude with age. When a stabilizing or destabilizing external force field was applied at the hip, both young and elderly participants adapted their multijoint coordination by lowering or respectively increasing their neuromuscular control actions around the ankles, expressed in a change of FRF magnitude. However, the elderly adapted less compared with the young participants. Model fits on the FRFs showed that elderly had higher intrinsic and reflexive stiffness of the ankle, together with higher time delays of the hip. Furthermore, the elderly adapted their reflexive stiffness around the ankle joint less compared with young participants. These results imply that elderly were stiffer and were less able to adapt to external force fields. PMID:26719084

Pathologic states are associated with a loss of dynamical complexity. Therefore, therapeutic interventions that increase physiologic complexity may enhance health status. Using multiscale entropy analysis, we show that the postural sway dynamics of healthy young and healthy elderly subjects are more complex than that of elderly subjects with a history of falls. Application of subsensory noise to the feet has been demonstrated to improve postural stability in the elderly. We next show that this therapy significantly increases the multiscale complexity of sway fluctuations in healthy elderly subjects. Quantification of changes in dynamical complexity of biologic variability may be the basis of a new approach to assessing risk and to predicting the efficacy of clinical interventions, including noise-based therapies.

We aimed to examine the effect of 2-year cognitive⁻motor dual-task (DT) training on cognitive functions and motor ability of healthy elderly people without marked cognitive impairment. From the 25 participants of our 12-week DT trial conducted in 2014, we recruited 8 subjects who voluntarily participated in a new DT training program once a week for 2 years (exercise (EX) group). Their cognitive functions were evaluated by the Modified Mini-Mental State (3MS) examination and the Trail Making Test, and results were compared with those of the 11 subjects who discontinued the training and did not perform any types of exercise for 2 years (non-exercise (NO) group). Subjects in the NO group showed deterioration in the 3MS examination results, especially in the cognitive domain of attention. Meanwhile, participation in DT training maintained the scores in almost all domains of cognitive function, as well as the total 3MS scores. However, both groups had impaired quadriceps muscle strength and motor ability after the 2-year observation period. These results suggest that participating in exercise program comprising DT training for 2 years may be beneficial for maintaining the broad domains of cognitive function in healthy elderly people, although further verification is needed.

Full Text Available Hantavirus disease in America has been recognizable because of its rapid progression in clinical cases, occurrence in previously healthy young adults, and high case fatality rate. Hantavirus disease has been proposed now to define the diversity of clinical manifestations. Since 1995, a total of 902 cases of hantavirus pulmonary syndrome have been reported in Chile, caused by Andes virus (ANDV, with overall fatality of 32%. This report describes the sero-epidemiology of hantavirus in apparently healthy people in rural and urban slum communities from southern Chile. Ten of 934 samples yielded a positive result resulting in a seroprevalence of 1.07% (95% confidence intervals: 0.05%–2.0%. A higher proportion of positive samples was found among individuals from rural villages (1.3% and slums (1.5% compared with farms (0.5%. Seropositivity was associated with age (p = 0.011, low education level (p = 0.006 and occupations linked to the household (homemaker, retired, or student (p = 0.016. No evidence of infection was found in 38 sigmodontinae rodents trapped in the peri-domestic environment. Our findings highlight that exposure risk was associated with less documented risk factors, such as women in slum and rural villages, and the occurrence of infection that may have presented as flu-like illness that did not require medical attention or was misdiagnosed.

Brain connectivity is highly dynamic, but functional connectivity (FC) studies using resting-state functional magnetic resonance imaging (rs-fMRI) assume it to be static. This study assessed differences in dynamic FC between young healthy adults (YH) and elderly healthy adults (EH) compared to static FC. Using rs-fMRI data from 12 YH and 31 EH, FC was assessed in six functional regions (subcortical, auditory [AUD], sensorimotor [SM], visuospatial [VS], cognitive control [CC], and default mode network [DMN]). Static FC was calculated as Fisher's z-transformed correlation coefficient. The sliding time window correlation (window size 30 s, step size 3 s) was applied for dynamic FC, and the standard deviation across sliding windows was calculated. Differences in static and dynamic FC between EH and YH were calculated and compared by region. EH showed decreased static FC in the subcortical, CC, and DMN regions (FDR corrected p = 0.0013; 74 regions), with no regions showing static FC higher than that in YH. EH showed increased dynamic FC in the subcortical, CC, and DMN regions, whereas decreased dynamic FC in CC and DMN regions (p < 0.01). However, the regions showing differences between EH and YH did not overlap between static and dynamic FC. Dynamic FC exhibited differences from static FC in EH and YH, mainly in regions involved in cognitive control and the DMN. Altered dynamic FC demonstrated both qualitatively and quantitatively distinct patterns of transient brain activity and needs to be studied as an imaging biomarker in the aging process. (orig.)

Liver diseases in the elderly have aroused less interest than diseases of other organs, since the liver plays a limited role in aging. There are no specific liver diseases of old age, but age-related anatomical and functional modifications of the liver cause changes in the frequency and clinical behavior of some liver diseases compared with those in younger patients. This review discusses the most important features of liver function in the healthy elderly population, as well as the features of the most prevalent liver diseases in this age group, especially the diagnostic approach to the most common liver problems in the elderly: asymptomatic elevation of serum transaminases and jaundice.

CT may be influenced by cultural and linguistic factors, but research examining CT programs has mostly been conducted on Western populations. We have developed an innovative electroencephalography (EEG-based brain–computer interface (BCI CT program that has shown preliminary efficacy in improving cognition in 32 healthy English-speaking elderly adults in Singapore. In this second pilot trial, we examine the acceptability, safety, and preliminary efficacy of our BCI CT program in healthy Chinese-speaking Singaporean elderly.Methods: Thirty-nine elderly participants were randomized into intervention (n=21 and waitlist control (n=18 arms. Intervention consisted of 24 half-hour sessions with our BCI-based CT training system to be completed in 8 weeks; the control arm received the same intervention after an initial 8-week waiting period. At the end of the training, a usability and acceptability questionnaire was administered. Efficacy was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS, which was translated and culturally adapted for the Chinese-speaking local population.

Dietary and life style practices differ in postpartum (PP) and nonpregnant Indian women. Effect of these practices on postpartum weight retention (PPWR) and development of cardio-metabolic risk (CMR) has been scarcely studied in urban women. Aims of this study were to (i) compare anthropometry, biochemical parameters and body composition up to 3 years PP (ii) effect of PPWR, dietary fat intake and physical activity on CMR factors. Cross-sectional, 300-fullterm, apparently healthy primi-parous women (28.6 ± 3.4 years) randomly selected. 128 women within 7-day of delivery (Group-A), 88 with 1-2 years (Group-B) and 84 with 3-4-year-old-children (Group-C) were studied. Anthropometry, sociodemographic status, physical activity, diet, clinical examination, biochemical tests, body composition, at total body (TB), by dual energy X-ray absorptiometry (GE-Lunar DPX) were collected. Women at 3-year PP showed higher weight retention (6.5[10] kg) than at 1-year (3.0[7] kg) (median [IQR]). Android fat % (central obesity) increased (P 0.1). Postdelivery, low physical activity and higher PPWR may increase CMR in Indian women.

Boirie, Yves; Morio, Béatrice; Caumon, Elodie; Cano, Noël J

2014-01-01

Protein-energy homeostasis is a major determinant of healthy aging. Inadequate nutritional intakes and physical activity, together with endocrine disturbances are associated with of sarcopenia and frailty. Guidelines from scientific societies mainly address the quantitative aspects of protein and energy nutrition in elderly. Besides these quantitative aspects of protein load, perspective strategies to promote muscle protein synthesis and prevent sarcopenia include pulse feeding, the use of fast proteins and the addition of leucine or citrulline to dietary protein. An integrated management of sarcopenia, taking into account the determinants of muscle wasting, i.e. nutrition, physical activity, anabolic factors such as androgens, vitamin D and n-3 polyunsaturated fatty acids status, needs to be tested in the prevention and treatment of sarcopenia. The importance of physical activity, specifically resistance training, is emphasized, not only in order to facilitate muscle protein anabolism but also to increase appetite and food intake in elderly people at risk of malnutrition. According to present data, healthy nutrition in elderly should respect the guidelines for protein and energy requirement, privilege a Mediterranean way of alimentation, and be associated with a regular physical activity. Further issues relate to the identification of the genetics determinants of protein energy wasting in elderly. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Objective: To evaluate the ability of volumetric bone mineral density (BMD) parameters of lumbar vertebrae in differentiating osteoporotic fractured from nonfractured elderly women with vQCT technique, and to compare the bony structural conditions of osteoporotic elderly women with healthy elderly women. Methods: Multi-slice CT spinal scans of L1 and L2 were acquired in 26 osteoporotic vertebral fractured elderly women (group one) and 30 nonfractured osteoporotic subjects (group two). All the retro-reconstructed images of L1 and L2 were sent to the workstation and processed by volume rendering (VR) technique to measure volumetric BMD (3D-INTGL, 3D-CORT, 3D-TRAB) and trabecular and integral BMD (2D-TRAB, 2D-INTGL) by conventional QCT technique. BMD indexes in DXA were AP-SPINE and bone mineral apparent density (BMAD) in anteroposterior position. The seven parameters between the two group s were compared. Ten healthy elderly women were selected as normal group to reformate 3D-VR images from MSCT images to analyze the bony structure and calculate the ratio of bone volume to total volume (BV/TV) in the center of L1 vertebrae, and to compare the index between the normal group and tenpatients randomly selected from the 56 osteoporotic women. Results: DXA measurements in group one: AP-SPINE and BMAD were (0.796±0.170)g/cm 2 and (272.7±27.7) mg/cm 3 , respectively, showing no statistically significant differences comparing with (0.817±0.140) g/cm 2 and (249.5 ± 26.5) mg/cm 3 in group two. Volumetric BMD in group one included 2D-TRAB (70.4 ± 22.2) mg/cm 3 , 2D-INTGL (138.3±35.1) mg/cm 3 , 3D-INTGL (139.4±34.9 ) mg/cm 3 , 3D-CORT (133.8±26.9) mg/cm 3 , and 3D-TRAB (69.9 ±18.6) mg/cm 3 , respectively, showing statistically differences with (89.1±21.8) mg/cm 3 , (170.6±34.5) mg/cm 3 , (180.5±28.2) mg/cm 3 , (163.2±27.5) mg/cm 3 , and (83.8 ± 17.1) mg/cm 3 in group two (the decrements 18%-23%). The mean value of BV/TV of L1 vertebrae was (8.12 ± 1.96)% in

Between 2007 and 2012, a double-blind randomized controlled trial was conducted in a rural area of North China. In all, 390 healthy participants aged 60-74 were randomly allocated to receive daily vitamin C (50 mg; control group) or vitamin C plus B vitamins (400 µg folic acid, 2 mg B6, and 10 µg B12; treatment group) for 12 months. FRSs were calculated for all 390 subjects. Folate and vitamin B12 plasma concentrations in the treatment group increased by 253 and 80%, respectively, after 6 months, stopped increasing with continued supplementation after 12 months and returned to baseline levels 6 months after supplementation cessation. Compared with the control group, there was no significant effect of B vitamin supplementation on FRSs after 6 months (mean difference -0.38; 95% CI -1.06, 0.31; p = 0.279), whereas a significant effect of supplementation was evident after 12 months (reduced magnitude 7.6%; -0.77; 95% CI -1.47, -0.06; p = 0.033). However, this reduction disappeared 6 months after supplementation stopped (-0.07; 95% CI -0.80, 0.66; p = 0.855). The reduction in FRS 12 months after supplementation was more pronounced in individuals with a folate deficiency (10.4%; -1.30; 95% CI -2.54, -0.07; p = 0.039) than in those without (4.1%; -0.38; 95% CI -1.12, 0.36; p = 0.313). B vitamins increased high-density lipoprotein cholesterol by 3.4% after 6 months (0.04; 95% CI -0.02, 0.10; p = 0.155) and by 9.2% after 12 months (0.11; 95 % CI 0.04, 0.18; p = 0.003). Compared with the control group, this change in magnitude decreased to 3.3% (0.04; 95 % CI -0.02, 0.10; p = 0.194) 6 months after supplementation cessation. Daily supplementation with a low-dose of B vitamins for 12 months reduced FRS, particularly in healthy elderly subjects with a folate deficiency. These reduced

Full Text Available Corals are rapidly declining globally due to coral diseases. Skeletal growth anomalies (SGA or coral tumors are a group of coral diseases that affect coral reefs worldwide, including Hong Kong waters in the Indo-Pacific region. To better understand how bacterial communities may vary in corals with SGA, for the first time, we examined the bacterial composition associated with the apparently healthy and the diseased tissues of SGA-affected Platgyra carnosus using 16S ribosomal rRNA gene pyrosequencing. Taxonomic analysis revealed Proteobacteria, Bacteroidetes, Cyanobacteria, and Actinobacteria as the main phyla in both the apparently healthy and the diseased tissues. A significant difference in the bacterial community composition was observed between the two conditions at the OTU level. Diseased tissues were associated with higher abundances of Acidobacteria and Gemmatimonadetes, and a lower abundance of Spirochaetes. Several OTUs belonging to Rhodobacteraceae, Rhizobiales, Gammaproteobacteria, and Cytophaga-Flavobacterium-Bacteroidetes (CFB were strongly associated with the diseased tissues. These groups of bacteria may contain potential pathogens involved with the development of SGA or opportunistic secondary or tertiary colonizers that proliferated upon the health-compromised coral host. We suggest that these bacterial groups to be further studied based on inoculation experiments and testing of Koch’s postulates in efforts to understand the etiology and progression of SGA.

This study investigated whether a 7-week yoga intervention could improve physical function, perceived stress, and mental/emotional wellness in elderly participants. 8 participants (66.5 ± 0.3 years) attended 2 60-min Hatha yoga sessions/week for 7 weeks, and performed pre- and post-intervention assessments. Balance was assessed using a 5-test battery. Flexibility was measured by sit-and-reach and shoulder flexibility tests. Functional mobility tests included 8-ft up-and-go, 5 chair stands, and 4-m walk. Participants completed SF-12, exhaustion level, and Perceived Stress Scale (PSS) questionnaires. SF-12 Mental Component Summary scores, exhaustion levels, and PSS scores improved post-intervention. No differences were found for physical function measures. Yoga participation can improve mental/emotional wellness, exhaustion levels, and stress levels in elderly individuals, even without measurable improvements in physical function. Clinicians and health practitioners who work with the elderly should consider yoga as a potential therapeutic modality for improving important aspects of quality of life in this population.

Future treatments of Alzheimer's disease need the identification of cases at high risk at the preclinical stage of the disease before the development of irreversible structural damage. We investigated here whether subtle cognitive deterioration in a population of healthy elderly individuals could be predicted by EEG signals at baseline under cognitive activation. Continuous EEG was recorded in 97 elderly control subjects and 45 age-matched mild cognitive impairment (MCI) cases during a simple attentional and a 2-back working memory task. Upon 18-month neuropsychological follow-up, the final sample included 55 stable (sCON) and 42 deteriorated (dCON) controls. We examined the P1, N1, P3, and PNwm event-related components as well as the oscillatory activities in the theta (4-7 Hz), alpha (8-13 Hz), and beta (14-25 Hz) frequency ranges (ERD/ERS: event-related desynchronization/synchronization, and ITC: inter-trial coherence). Behavioral performance, P1, and N1 components were comparable in all groups. The P3, PNwm, and all oscillatory activity indices were altered in MCI cases compared to controls. Only three EEG indices distinguished the two control groups: alpha and beta ERD (dCON >  sCON) and beta ITC (dCON memory processes but mostly affects attention, resulting in an enhanced recruitment of attentional resources. In addition, cognitive decline alters neural firing synchronization at high frequencies (14-25 Hz) at early stages, and possibly affects lower frequencies (4-13 Hz) only at more severe stages.

In addition to the well-documented loss of muscle mass and strength associated with aging, there is evidence for the attenuating effects of aging on the number of satellite cells in human skeletal muscle. The aim of this study was to investigate the response of satellite cells in elderly men...... and women to 12 weeks of resistance training. Biopsies were collected from the m. vastus lateralis of 13 healthy elderly men and 16 healthy elderly women (mean age 76+/-SD 3 years) before and after the training period. Satellite cells were visualized by immunohistochemical staining of muscle cross.......15+/-0.06; mean+/-SD) and females (from 0.11+/-0.04 to 0.13+/-0.05). These results suggest that 12 weeks of resistance training is effective in enhancing the satellite cell pool in skeletal muscle in the elderly....

Dysfunctional prediction in sensory processing has been suggested as a possible causal mechanism in the development of delusions in patients with schizophrenia. Previous studies in healthy subjects have shown that while the perception of apparent motion can mask visual events along the illusory motion trace, such motion masking is reduced when events are spatio-temporally compatible with the illusion, and, therefore, predictable. Here we tested the hypothesis that this specific detection advantage for predictable target stimuli on the apparent motion trace is reduced in patients with paranoid schizophrenia. Our data show that, although target detection along the illusory motion trace is generally impaired, both patients and healthy control participants detect predictable targets more often than unpredictable targets. Patients had a stronger motion masking effect when compared to controls. However, patients showed the same advantage in the detection of predictable targets as healthy control subjects. Our findings reveal stronger motion masking but intact prediction of visual events along the apparent motion trace in patients with paranoid schizophrenia and suggest that the sensory prediction mechanism underlying apparent motion is not impaired in paranoid schizophrenia.

Full Text Available We hypothesize that improvements in the gut microbiota are capable of ameliorating gut permeability and, consequently, reducing systemic inflammation and the risk of frailty. This study aims to evaluate some effects of synbiotic supplementation on inflammatory markers and the body composition of the elderly at risk of frailty. In a double-blind study that lasted three months, 17 elderly individuals fulfilling one frailty criteria (grip strength were randomly distributed into two groups: SYN (n = 9, daily intake of synbiotic (6 g Frutooligossacarides, 108 to 109 CFU Lactobacillus paracasei, 108 to 109 CFU Lactobacillus rhamnosus, 108 to 109 CFU Lactobacillus acidophilus and 108 to 109 CFU Bifidobacterium lactis, or placebo (maltodextrin; PLA; n = 8. Subjects were analyzed for anthropometric measurements, bioelectric impedance with vectorial analysis (BIVA, IL-6 and TNF-α. A comparison between groups did not show any difference for the variables investigated. In turn, individual analysis of electrical impedance (BIVA demonstrated that the majority of SYN individuals maintained or improved their tissue hydration, when compared to the PLA group after supplementation. In conclusion, three months of synbiotic supplementation did not promote any significant changes in inflammatory cytokines or body composition, but demonstrated a trend towards a preservation of hydration status in apparently healthy elderly individuals.

Full Text Available Given the rapid increase in the number and share of the elderly in the total population, good healthand healthy ageing are an important factor in the socio-economic development of ageing societies. Selfperceivedhealth is one of the most important health and well-being indicators. The article presents theresults of research on self-perceived elderly health based on data from "Household Budget Survey" for2006-2015 (NBS. The study reveals a slow increase in life expectancy and healthy life expectancy, as wellas time spent in good health. The life expectancy without chronic illness is lower than healthy lifeexpectancy. There is a positive rise in the self-assessment of the elderly for both sexes and at different agesafter 60 years. The regression analysis of factors influencing self-perceived health (age, sex, education level,welfare level, degree of disability and civil status, demonstrates that among the most important factors withwhich self-responding health is associated, as bad and very bad were highlighted the low level of educationand material welfare, as well as the presence of behavioural vices (smoking.

Today, AIAN Elders are more actively engaged in their families and communities, encouraging the development of intergenerational programs, language and cultural revitalization, being stewards in research conducted in their communities, as well passing on their knowledge and experiences on how to live as healthy Native people. Elders have traditionally been quiet and observant of their environment, but the current and future cohorts of Elders are advocates, leaders, and culture bearers for their families and communities and they are now in positions of leadership. Western society acknowledges the value of traditional knowledge and AIAN Elders are viewed as exemplars of healthy aging and their lessons and experiences can be attributed to our own lives. This commentary highlights the paradigm shift in how society views older adults, specifically AIAN Elders and their role in health and wellbeing.

Full Text Available Abstract Although the main initial deficit is considered to be in the memory domain, an early impairment of executive functions is also found in AD where these deficits are correlated to functional impairment. Ecological tests are more indicated to evaluate executive impairment, and are better able to assist in treating AD patients than more commonly used tests. Objectives: The aim of this preliminary study is to verify the performance in executive functions using the Behavioural Assessment of the Dysexecutive Syndrome (BADS in elder controls and mild AD patients, and to analyze its applicability in our environment. Methods: The BADS was performed by 17 healthy elders and 17 early AD patients matched for age, schooling and gender. Results: There were significant differences among controls and AD patients on MMSE scores, and in measures of executive functions, memory, and motor speed. Some sub items of BADS (rule shift cards, modified six elements, total score, standard, standard by age and overall classification by age were also different between groups. Differences were also significant on the Dysexecutive Questionnaire (DEX of BADS self-ratings and other-ratings. Conclusion: BADS was efficacious in detecting executive deficits in this sample, as confirmed by other executive functions tests applied.

Despite significant success of the Global Polio Eradication Initiative (GPEI) in Nigeria, Afghanistan, India, Pakistan, wild poliovirus still occurs due to persistently high proportions of under and unimmunized children. The study aimed at determining the type of poliovirus often excreted into the environment. Four hundred nine fecal samples collected from apparently healthy school children aged 5-16 years in Borno and Adamawa States, northeastern Nigeria, were tested for poliovirus by tissue culture technique. The isolates were characterized further by intratypic differentiation testing and genetic sequencing. Three wild poliovirus type, 11 Sabin type, combination of Sabin-types 1 + 2 and 2 + 3 poliovirus, and 22 non-polio enteroviruses were obtained. The continued excretion of wild-type poliovirus among children above 5 years old vaccinated with oral polio vaccine contributes to the persistent circulation of these viruses in the environment and may limit the population immunity. However, the excreted Sabin poliovirus is capable of immunizing the unvaccinated children and promotes herd immunity. Similarly, the excretion of combination of two polio serotypes indicates the child susceptibility to the missing serotype (s) and therefore indicates an immunity gap. The common unhygienic practices in the environment could aid the spread of these viruses through oral-fecal route. Asymptomatic transmission of wild poliovirus among older oral polio vaccine-vaccinated children poses a serious threat to polio eradication program in Nigeria and therefore, environmental and serological surveillance with larger sample size are important for monitoring poliovirus circulation in Nigeria.

The study was carried out in eight dogs slaughtering outlets within four Local Government Areas of the State for the determination of rabies antigen in the saliva and brain of apparently healthy dogs slaughtered for human consumption. A total of one hundred (100) samples each of saliva and brain were collected before and after slaughter, respectively, between April to June, 2013, in the selected areas. The saliva was subjected to rapid immune-chromatographic test (RICT) while direct fluorescent antibody test (DFAT) was carried out on the brain samples. Structured questionnaire was administered to nineteen (19) dog meat processors comprising 18 males and 1 female in the selected areas. Sixty four percent of the samples tested were from female dogs while 36% were from males, 5% tested positive for rabies antigen with the use of both tests; there was no statistical association between sex and rabies status of the dogs sampled (P > 0.05). Butchers bitten during the course of slaughtering were 94.7% out of which 72.8% utilized traditional method of treatment and only 27.8% reported to the hospital for proper medical attention. This study has established the presence of rabies antigen in apparently healthy dogs in the study area.

Full Text Available Objectives: The aim of this study was to investigate the response of plasma Myostatin and insulin growth factor like-1 (IGF-1, as two most important proteins that involved in Cachexia syndrome, to acute resistance exercise in healthy elderly people. Methods & Materials: Twelve healthy older men (Age=67±1.3 years, BMI=25±1.4 kg/m2 volunteered for participation in this study. 72 hours after the determination of muscular maximal strength (by 1-RM test, subjects participated in acute resistance exercises via 75% 1-RM. In this research, two blood samples were collected at before and immediately after the exercise from Antecubital vein. Plasma Myostatin and serum levels of IGF-1 were measured by ELISA methods. Paired T-Test used for statical analyses of research data. Significant level was set at P≤0.05. Results: The results of this study showed that plasma Myostatin significantly decreased in response to resistance exercise (P=0.0001. Also the serum levels of IGF-1 increased significantly in response to resistance exercise (P=0.0001. In turn, the results reveled that the IGF-1 to Myostatin ratio increased significantly in response to resistance exercise (P=0.001. Conclusion: The results of this study showed that resistance exercise through increases of IGF-1 and decreases of Myostatin causes increment of IGF-1 to Myostatin ratio. According to the results of this study it seems prescription of resistance exercise could positive changes in proteins that involved in Cachexia syndrome in elderly people. Presumably, through this way we can prevent from Cachexia and its many physiological and physical related dysfunctions in theses people. Although more study is needed to clear its mechanisms.

Full Text Available INTRODUCTION: Studies document a change in memory during the process of aging. However, studies report the possibility of improvement after training. OBJECTIVE: To replicate international findings regarding the effects of memory training with a sample of Brazilian elders and to investigate mechanisms, such as the use of strategies, that can explain its benefits. METHODS: 69 healthy Brazilian elders were randomly divided into an experimental group (EG and a control group (CG, and received four sessions of training (CG received training after pos-test. Training included information on memory and the process of aging, instruction and practice in organizing grocery lists and the underlining of main ideas in short texts. RESULTS: There was superior improvement for prose recall and greater use of strategies (organizing lists and underlining texts for the EG at post-test. Both groups reported fewer memory complaints (assessed with the MAC-Q and faster information processing (WAIS-R Digit Symbols sub-test. CONCLUSIONS: After training, elders intensify the use of strategies, however, this fact does not guarantee a better performance (there was no significant improvement in list recalls. List recall results suggest the presence of the utilization deficiency: elders used the strategy but failed to benefit from it.

Designing a system for the elderly is crucial, as aging is associated with physiological changes that may impair perception, cognition and other social aspects; therefore, many aspects need consideration, especially in interface design. This study was conducted to develop a digital nutritional education package (WE Sihat) by following appropriate guidelines for elderly people to achieve better design interface and interaction. Touch-screen technology was used as a platform for user interaction. The nutritional content was based on previous nutrition studies and a lifestyle education package on healthy aging, which contains four modules. The questionnaires were distributed to 31 Malay subjects aged 60-76 years old, containing an evaluation about the overall content, graphics, design layout, colour, font size, audio/video, user-perceived satisfaction and acceptance levels. The findings showed positive feedback and acceptance. Most subjects agreed that the digital nutritional education package can increase their nutritional knowledge for a healthy lifestyle and is easy to use. The touch-screen technology was also well accepted by elderly people and can be used as a kiosk for disseminating nutrition education for healthy aging.

OBJECTIVE: To test the hypothesis that quantitative measures of gait unsteadiness are increased in community-dwelling elderly fallers. STUDY DESIGN: Retrospective, case-control study. SETTING: General community. PARTICIPANTS: Thirty-five community-dwelling elderly subjects older than 70 years of age who were capable of ambulating independently for 6 minutes were categorized as fallers (age, 82.2 +/- 4.9 yrs [mean +/- SD]; n = 18) and nonfallers (age, 76.5 +/- 4.0 yrs; n = 17) based on history; 22 young (age, 24.6 +/- 1.9 yrs), healthy subjects also participated as a second reference group. MAIN OUTCOME MEASURES: Stride-to-stride variability (standard deviation and coefficient of variation) of stride time, stance time, swing time, and percent stance time measured during a 6-minute walk. RESULTS: All measures of gait variability were significantly greater in the elderly fallers compared with both the elderly nonfallers and the young subjects (p elderly fallers was similar to that of the nonfallers. There were little or no differences in the variability measures of the elderly nonfallers compared with the young subjects. CONCLUSIONS: Stride-to-stride temporal variations of gait are relatively unchanged in community-dwelling elderly nonfallers, but are significantly increased in elderly fallers. Quantitative measurement of gait unsteadiness may be useful in assessing fall risk in the elderly.

Symptoms and other abnormalities associated with serum sodium imbalance were studied in bedridden elderly and healthy elderly subjects. 1. A significantly higher number of the bedridden elderly suffered from chronic wasting disease. 2. The average serum sodium concentration in bedridden elderly subjects was significantly lower than in healthy subjects, as was the sodium intake and the sodium content in urine, which indicate that the bedridden elderly subjects suffered from chronic sodium deficiency. 3. The bedridden elderly subjects had high levels of plasma PRA and antidiuretic hormone, and their aldosterone levels were low, which indicate that their condition was associated with a decrease in available circulating plasma, hypersecretion of antidiuretic hormone, and a decline in the ability to retain sodium. 4. Measurement of 24-hr creatinine clearance, albumin, and beta 2-microglobulin in urine revealed that bedridden elderly subjects had high levels of renal dysfunction, the result of which may a disturbance in water excretion. Abnormalities in serum sodium levels in the bedridden elderly subjects were related to a chronic deficiency in sodium intake, which reduced their ability to maintain sodium levels and impaired their renal function. Iatrogenic factors are likely to play an important role in the genesis of this condition, and should be taken into account in during management.

Recent studies have demonstrated that transcranial direct current stimulation (tDCS) is potentially useful to improve working memory. In the present study, young and elderly subjects performed a working memory task ( n -back task) during an electroencephalogram recording before and after receiving anodal, cathodal, and sham tDCS over the left dorsolateral prefrontal cortex (DLPFC). We investigated modulations of behavioral performance and electrophysiological correlates of working memory processes (frontal and parietal P300 event-related potentials). A strong tendency to modulated working memory performance was observed after the application of tDCS. In detail, young, but not elderly, subjects benefited from additional practice in the absence of real tDCS, as indicated by their more accurate responses after sham tDCS. The cathodal tDCS had no effect in any group of participants. Importantly, anodal tDCS improved accuracy in elderly. Moreover, increased accuracy after anodal tDCS was correlated with a larger frontal P300 amplitude. These findings suggest that, in elderly subjects, improved working memory after anodal tDCS applied over the left DLPFC may be related to the promotion of frontal compensatory mechanisms, which are related to attentional processes.

Full Text Available This paper reports on a rare case of fetal papyraceous mummification after asymptomatic uterine rupture in an elderly female dog with pyometra. The patient had a history of mating six months before the examination but no apparent signs of gestation or parturition. Exploratory laparotomy was used to identify a rupture of the left uterine horn and the presence of cystic endometrial hyperplasia and pyometra. Two mummified papyraceous fetuses were observed in the abdominal cavity and had adhered to the spleen, pancreas, intestine and omentum. Ovariehysterectomy and corrective surgery were performed. The patient had remained healthy after uterine rupture until a new estrous cycle and the development of pyometra. Bitches that are 10 years old or more are predisposed to implantation failure, pregnancy or parturition problems and they should not be breed to avoid complications.

A positive discourse about ‘healthy aging’ and ‘active aging’ shapes many health policies targeting the elderly. Rather than portraying old age as a life stage of passivity and decline, this discourse transforms late life into a period of physical activity and fulfilling social involvement...... – especially in terms of engagement with one’s family, friends, and ‘community’. Based on ethnographic fieldwork conducted in a Danish municipality, the chapter examines how health-promotion activities targeted at the elderly function in practice, and discusses the various forms of ‘community...... that may constitute different collectives within the politically delineated geographic borders of the municipality, the chapter describes some of the social, cultural, and political practices that connect various forms of ‘community’, and how these practices may affect (and be affected by) elderly citizens...

The purpose of the current study was to define the impact of regular practice of Nordic walking on the gait of the elderly. Thereby, we aimed to determine whether the gait characteristics of active elderly persons practicing Nordic walking are more similar to healthy adults than that of the sedentary elderly. Comparison was made based on parameters computed from three inertial sensors during walking at a freely chosen velocity. Results showed differences in gait pattern in terms of the amplitude computed from acceleration and angular velocity at the lumbar region (root mean square), the distribution (Skewness) quantified from the vertical and Euclidean norm of the lumbar acceleration, the complexity (Sample Entropy) of the mediolateral component of lumbar angular velocity and the Euclidean norm of the shank acceleration and angular velocity, the regularity of the lower limbs, the spatiotemporal parameters and the variability (standard deviation) of stance and stride durations. These findings reveal that the pattern of active elderly differs significantly from sedentary elderly of the same age while similarity was observed between the active elderly and healthy adults. These results advance that regular physical activity such as Nordic walking may counteract the deterioration of gait quality that occurs with aging.

The objectives of this study were to examine the relationship between APOE epsilon4 and subjective effects of trihexyphenidyl on measures reflecting sedation and confusion and to investigate the relationship between trihexyphenidyl-induced subjective effects and objective memory performance. This study comprised 24 cognitively intact, health elderly adults (12 APOE epsilon4 carriers) at an outpatient geriatric psychiatry research clinic. This was a randomized, double blind, placebo-controlled, three-way, crossover experimental design. All participants received 1.0 mg or 2.0 mg trihexyphenidyl or placebo administered in counterbalanced sequences over a period of three consecutive weeks. Bond and Lader's visual analog scales and alternate versions of the Buschke Selective Reminding Test were administered in a repeated measures design at baseline, 1, 2.5, and 5 hours postdrug administration. A 2.0-mg oral dose of trihexyphenidyl resulted in increased subjective ratings of mental slowness in carriers of the APOE epsilon4 allele only. Drug effects as determined by difference scores between 2.0 mg trihexyphenidyl and placebo on ratings of mental slowness significantly correlated with total and delayed recall on the Buschke Selective Reminding Test in carriers of the APOE epsilon4 allele only. However, no significant effects were found with other visual analog scales reflecting subjective sedation and clear-headedness. The epsilon4 allele in healthy elderly was associated with increased subjective mental slowing after trihexyphenidyl anticholinergic challenge.

A blood sample and muscle biopsies were obtained from 54 elderly subjects. Twenty-seven subjects aged 77+/-3 years, had experienced a change in fat free mass (FFM) of +194+/-282g/year (lean body mass maintainers) and 27 subjects aged 78+/-3 years, had a change in FFM of -487+/-209g/year (lean body mass losers). Muscle biopsies were also obtained from 10 healthy subjects aged 34+/-4 years. In muscle, the ratio of mitochondrial DNA (mtDNA) to nuclear DNA (nDNA) and telomere length were assessed and deposition of 4-hydroxy-2-nonenal adducts (4HNE) was visualized by electron microscopy. In FFM maintainers, losers and young controls, the ratio of mtDNA to nDNA was 2.1 (95% confidence intervals (CI), 0.1-31.7), 1.5 (95% CI, 0.2-15.7) and 18.6 (95% CI, 2.8-46.2), respectively. 4HNE deposition was 5.9 (95% CI, 1.5-28), 4.9 (95% CI, 0.9-13) and 3.4 (95% CI, 1.1-4.6) gold particles/microm(2), respectively. Telomere length, expressed as T/S ratio, was 0.06 (95% CI, 0.01-0.16), 0.06 (95% CI, 0.03-0.27) and 0.34 (95% CI, 0.1-1.34), respectively (p<0.02 or less for all comparisons between elderly and young subjects).

Type 2 diabetes mellitus (DM) is known to be closely associated with lifestyle and obesity and has a prevalence that increases with age. This study aimed to assess the short-term composite effect of diet, physical activity, psychosocial health, and waist circumference (WC) on the incidence of DM in the elderly and to provide a lifestyle-based predictive index.We used baseline measurements (2009-2013) of 5349 community-dwelling participants (aged 55 years and older, 52% female) of the Healthy Aging Longitudinal Study in Taiwan (HALST) for fasting plasma glucose, HbA1C, serum cholesterol, triglycerides, blood pressures, WC, and outcomes of home-visit questionnaire. Principal component analysis (PCA) was used to identify participants with a healthy lifestyle (HLF: higher diet, physical activity, and psychosocial scores) and a lower WC, with cutoffs determined by the receiver-operating characteristics. A Cox regression model was applied to 3424 participants without DM at baseline by linking to their National Health Insurance records (median follow-up of 3.1 years).In total, 247 new DM cases (7.2%) were identified. The HLF and lower WC group had a relative risk (RR) of DM of 0.54 (95% CI 0.35-0.82) compared to the non-HLF and higher WC group. When stratified by the presence of impaired glucose tolerance (IGT) or metabolic syndrome (MS), only participants with IGT/MS showed significant risks (RR 0.55; 95% CI 0.33-0.92). However, except for WC, the individual lifestyle factors were nonsignificant in the overall model without PCA.A composite protective effect of HLF and normal WC on DM within 5 years was observed, especially in those with IGT or MS. Psychosocial health constituted an important lifestyle factor in the elderly. The cutoffs identified could be used as a lifestyle-based risk index for DM. Maintaining an HLF to prevent DM is especially important for the elderly.

To establish standard apparent diffusion coefficient (ADC) and the fat content as a function of age, gender and body mass index (BMI) in healthy parotid glands, and to address the influences of fat suppression on ADC measurements. A total of 100 healthy adults (gender and age evenly distributed) were prospectively recruited, with parotid fat content measured from gradient-echo images with fat-water separated using iterative decomposition with echo asymmetry and least squares (IDEAL). The ADCs were estimated using both fat-saturated and non-fat-saturated diffusion-weighted imaging via a periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) technique. Parotid fat content was larger in men than in women by about 10 percentage points (P < 0.005), and positively associated with BMI and age for both genders (mostly with P < 0.001). ADCs estimated with non-fat-saturated PROPELLER were significantly lower in men than in women (P < 0.005), but showed no gender difference if measured using fat-saturated PROPELLER (P = 0.840). The negative association between parotid ADC and age/BMI/fat (P < 0.001) showed greater regression slopes in non-fat-saturated PROPELLER than in fat-saturated data. Parotid fat content in healthy adults correlates positively with both age and BMI; the correlation with age is gender-dependent. Parotid ADC measurements are strongly influenced by fat saturation.

The purpose of this study was to investigate whether vaginal administration of probiotic Lactobacillus results in their colonization and persistence in the vagina and whether it promotes normalization and maintenance of pH and Nugent score. A single-arm, open-label controlled towards the baseline (pre-post) study including 35 apparently healthy women was conducted. Each woman was examined three times during the study. Women were instructed to receive daily for 7 days, the probiotic suppositories SYNBIO(®) gin (Lactobacillus rhamnosus IMC 501(®) and Lactobacillus paracasei IMC 502(®)). Vaginal swabs were collected during visit 1, 2, and 3 to determine the total lactobacilli count, the presence of the two administered bacteria, the measure of the pH, and the estimation of Nugent score. Evaluation of treatment tolerability was based on analysis of the type and occurrence of adverse events. The probiotic vaginal suppository was well tolerated and no side effects were reported. Intermediate Nugent score was registered in 40 % of women at visit 1 and these intermediate scores reverted to normal at day 7 (end of treatment) in 20 % of subjects. Administration of SYNBIO(®) gin contributed to a significant increase in the lactobacilli level at visit 2. Molecular typing revealed the presence of the two strains originating from SYNBIO(®) gin in 100 % of women at visit 2 and 34 % at visit 3. No significant changes were registered for pH between visits. The SYNBIO(®) gin product is safe for daily use in healthy women and it could be useful to restore and maintain a normal vaginal microbiota.

While aging is unavoidable, the aging mechanism is still unclear because of its complexity. Smoking causes premature death and is considered as an environmental aging accelerator. In the present study, we focused on the influence of smoking to the serum concentration of anti-aging protein α-klotho (αKl) and the β-klotho-associated protein fibroblast growth factor (FGF)-21 in men. Subjects consisted of apparently healthy men over 40 years of age who underwent health examination. Physical and biochemical parameters, including the levels of several cytokines and growth factors, were obtained from the subjects. Among middle-aged men (46.1 ± 5.1 years), serum levels of FGF-21, soluble αKl (sαKl), and inflammation-related cytokine interleukin (IL)-6 were significantly higher in smokers than in never-smokers. Serum levels of FGF-21 increased and correlated with alanine transaminase, γ guanosine-5'-triphosphate, and total cholesterol only in smokers, suggesting FGF-21 as a metabolic disorder-related factor in smokers. In aged men (60.3 ± 1.7 years), although the serum levels of sαKl in never-smokers were low, smokers showed highly increased serum levels of sαKl. Serum levels of sαKl was correlated with IL-6 in middle-aged never-smokers, suggesting sαKl regulates IL-6. However, this correlation was disrupted in smokers and aged men.

Management of chronic constipation in the elderly.

LENUS (Irish Health Repository)

Gallagher, Paul F

2012-02-03

Constipation is a significant healthcare problem in the elderly. However, while undoubtedly common in the elderly, data on the prevalence of constipation in general and of its subtypes vary considerably, depending on the nature of the study population and their location. Furthermore, the complexity of the pathophysiology of constipation in this age group is little appreciated. Assumptions regarding \\'age-related changes in colorectal physiology\\' are, for the most part, not supported by scientific evidence and may serve to distract the clinician from uncovering the contributions of co-morbid diseases and the impact of iatrogenic factors. The evidence base from which one can develop recommendations on the management of constipation in the elderly is, for the most part, slim. This becomes most starkly apparent when one attempts to critically assess specific approaches to management. There is insufficient evidence to support the use of many commonly used laxatives both in the general population and in the elderly. Lifestyle interventions have value for some patients but data are lacking on the benefits of these interventions for patients with chronic constipation. Data in the elderly do not exist for most new pharmacological approaches to constipation. Pending the availability of good data, management of constipation in the elderly should be tailored to each individual\\'s needs and expectations, regardless of age or place of residence. In certain situations, constipation may be complicated by the development of impaction; preventive strategies are important in this context. We urge enrolment of many more elderly individuals with chronic constipation in clinical trials designed to address their particular needs.

Andropausal and depressive symptoms are common in aging males and may be associated with hormone deficiency. We investigated the severity of andropausal and depressive symptoms, as well as their hormonal determinants, in 196 middle-aged and elderly men (age range: 40-80 years) with prediabetes (PD) and in 184 healthy peers. PD was diagnosed according to the definition of the American Diabetes Association. The severity of andropausal and depressive symptoms was assessed using the Aging Males' Symptoms Rating Scale and the Self-Rating Depression Scale. Total testosterone (TT), calculated free testosterone (cFT), dehydroepiandrosterone sulfate (DHEAS), and insulin-like growth factor 1 (IGF-1) were measured. The prevalence of andropausal syndrome in men with PD was significantly higher than that in healthy men (35% vs 11%, respectively). In men with PD aged 40-59 years, the severity of sexual, psychological, and all andropausal symptoms was greater than in healthy peers, while in elderly men (60-80 years), only the severity of psychological symptoms was greater than in healthy peers. The severity of depressive symptoms in the middle-aged men with PD was greater than in healthy peers, while the severity of depressive symptoms in elderly men with PD and healthy peers was similar. The higher prevalence of andropausal symptoms was independently associated with cFT and IGF-1 in middle-aged men and with TT and DHEAS in elderly men with PD. The more severe depression symptoms were associated with low TT and DHEAS in middle-aged men and with low cFT and DHEAS in elderly men with PD. In conclusion, the prevalence of andropausal symptoms, especially psychological, was higher in prediabetic patients as compared to healthy men, while the severity of depressive symptoms was higher only in middle-aged men with PD. Hormonal determinants of andropausal and depressive symptoms are different in middle-aged and elderly patients, but endocrine tests are necessary in all men with PD.

Cortisol homeostasis is important for healthy brain and cognitive aging. The aim of the current study is to investigate the role of serum cortisol levels in the relationship between regional brain volumes and cognitive processing speed in a group of cognitively normal elderly subjects. Forty-one healthy elderly participants were from a parallel longitudinal study. The reported data in this study reflects baseline measurements. Whole-brain anatomical scanning was performed using a 3.0 Tesla Philips Medical Systems Achieva scanner. Cognitive processing speed was assessed by the digit-symbol and symbol search tests, from the Chinese version of the Wechsler Adult Intelligence Scale—third edition (WAIS-III). Serum cortisol levels (sampled in the late morning) were measured by ELISA kits. Whole-brain regression analysis revealed that serum cortisol levels positively predicted the white matter volumes (WMV) of the right thalamus, the gray matter volumes (GMV) of the left thalamus and right cerebellar tonsil, and negatively predicted the WMV and GMV of the left middle temporal gyrus (MTG) in 41 healthy elderly participants. Furthermore, serum cortisol significantly moderated the relationship between the GMV of the left MTG and processing speed, as well as the GMV of the left thalamus and processing speed. This study provided the first piece of evidence supporting serum cortisol levels in moderating the relationship between regional brain volumes and processing speed in healthy elderly subjects. This observation enriches our understanding of the role of cortisol in brain morphology and cognitive functioning. PMID:28596732

The World Health Organization (WHO) has formulated guidelines for a healthy diet to prevent chronic diseases and postpone death worldwide. Our objective was to investigate the association between the WHO guidelines, measured using the Healthy Diet Indicator (HDI), and all-cause mortality in elderly men and women from Europe and the United States. We analyzed data from 396,391 participants (42% women) in 11 prospective cohort studies who were 60 years of age or older at enrollment (in 1988-2005). HDI scores were based on 6 nutrients and 1 food group and ranged from 0 (least healthy diet) to 70 (healthiest diet). Adjusted cohort-specific hazard ratios were derived by using Cox proportional hazards regression and subsequently pooled using random-effects meta-analysis. During 4,497,957 person-years of follow-up, 84,978 deaths occurred. Median HDI scores ranged from 40 to 54 points across cohorts. For a 10-point increase in HDI score (representing adherence to an additional WHO guideline), the pooled adjusted hazard ratios were 0.90 (95% confidence interval (CI): 0.87, 0.93) for men and women combined, 0.89 (95% CI: 0.85, 0.92) for men, and 0.90 (95% CI: 0.85, 0.95) for women. These estimates translate to an increased life expectancy of 2 years at the age of 60 years. Greater adherence to the WHO guidelines is associated with greater longevity in elderly men and women in Europe and the United States. © The Author 2014.

Associations of amylin with inflammatory markers and metabolic syndrome in apparently healthy Chinese.

Directory of Open Access Journals (Sweden)

Xinwei Hou

Full Text Available BACKGROUND: Cellular and animal studies implicate multiple roles of amylin in regulating insulin action, glucose and lipid metabolisms. However, the role of amylin in obesity related metabolic disorders has not been thoroughly investigated in humans. Therefore, we aimed to evaluate the distribution of circulating amylin and its association with metabolic syndrome (MetS and explore if this association is influenced by obesity, inflammatory markers or insulin resistance in apparently healthy Chinese. METHODS: A population-based sample of 1,011 Chinese men and women aged 35-54 years was employed to measure plasma amylin, inflammatory markers (C-reactive protein [CRP] and interleukin-6 [IL-6], insulin, glucose and lipid profiles. MetS was defined according to the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian-Americans. RESULTS: Plasma amylin concentrations were higher in overweight/obese participants than normal-weight counterparts (P<0.001 without sex difference. Circulating amylin was positively associated with CRP, IL-6, BMI, waist circumference, blood pressure, fasting glucose, insulin, amylin/insulin ratio, HOMA-IR, LDL cholesterol and triglycerides, while negatively associated with HDL cholesterol (all P<0.001. After multiple adjustments, the risk of MetS was significantly higher (odds ratio 3.71; 95% confidence interval: 2.53 to 5.46 comparing the highest with the lowest amylin quartile. The association remained significant even further controlling for BMI, inflammatory markers, insulin or HOMA-IR. CONCLUSIONS: Our study suggests that amylin is strongly associated with inflammatory markers and MetS. The amylin-MetS association is independent of established risk factors of MetS, including obesity, inflammatory markers and insulin resistance. The causal role of hyperamylinemia in the development of MetS needs to be confirmed prospectively.

A clear association has been demonstrated between gait stability and falls in the elderly. Integration of wearable computing and human dynamic stability measures into home automation systems may help differentiate fall-prone individuals in a residential environment. The objective of the current study was to evaluate the capability of a pair of electronic textile (e-textile) pants system to assess local dynamic stability and to differentiate motion-impaired elderly from their healthy counterparts. A pair of e-textile pants comprised of numerous e-TAGs at locations corresponding to lower extremity joints was developed to collect acceleration, angular velocity and piezoelectric data. Four motion-impaired elderly together with nine healthy individuals (both young and old) participated in treadmill walking with a motion capture system simultaneously collecting kinematic data. Local dynamic stability, characterized by maximum Lyapunov exponent, was computed based on vertical acceleration and angular velocity at lower extremity joints for the measurements from both e-textile and motion capture systems. Results indicated that the motion-impaired elderly had significantly higher maximum Lyapunov exponents (computed from vertical acceleration data) than healthy individuals at the right ankle and hip joints. In addition, maximum Lyapunov exponents assessed by the motion capture system were found to be significantly higher than those assessed by the e-textile system. Despite the difference between these measurement techniques, attaching accelerometers at the ankle and hip joints was shown to be an effective sensor configuration. It was concluded that the e-textile pants system, via dynamic stability assessment, has the potential to identify motion-impaired elderly.

Aging causes physiological and functional changes that impair pulmonary function. Incentive spirometry is widely used for lung expansion, but the effects of volume-oriented incentive spirometry (VIS) versus flow-oriented incentive spirometry (FIS) on chest wall volumes, inspiratory muscle activity, and thoracoabdominal synchrony in the elderly are poorly understood. We compared VIS and FIS in elderly subjects and healthy adult subjects. Sixteen elderly subjects (9 women, mean ± SD age 70.6 ± 3.9 y, mean ± SD body mass index 23.8 ± 2.5 kg/m(2)) and 16 healthy adults (8 women, mean ± age 25.9 ± 4.3 y, mean ± body mass index 23.6 ± 2.4 kg/m(2)) performed quiet breathing, VIS, and FIS in randomized sequence. Chest wall kinematics (via optoelectronic plethysmography) and inspiratory muscle activity (via surface electromyography) were assessed simultaneously. Synchrony between the superior thorax and abdominal motion was calculated (phase angle). In the elderly subjects both types of incentive spirometry increased chest wall volumes similarly, whereas in the healthy adult subjects VIS increased the chest wall volume more than did FIS. FIS and VIS triggered similar lower thoracoabdominal synchrony in the elderly subjects, whereas in the healthy adults FIS induced lower synchrony than did VIS. FIS required more muscle activity in the elderly subjects to create an increase in chest wall volume. Incentive spirometry performance is influenced by age, and the differences between elderly and healthy adults response should be considered in clinical practice.

Healthy elderly citizens living in their own homes may benefit from having replaced their existing indoor lighting with a lighting being superior in stimulating their circadian rhythm to improve sleep and general wellbeing. This was hypothesised in the presented study. We replaced the existing...... indoor lighting in the main living room of elderly citizens in 20 uniform private houses in a suburb of Copenhagen. In a randomized cross-over design 29 healthy participants over 65 years were exposed over 3 weeks to blue-enriched and 3 weeks to blue-deprived light with similar corneal photopic...... illuminances from 8 am to 13 pm. The two light epochs were separated by one week neutral indoor light. Daylight factors were measured for each of the houses. The pre-experimental lighting conditions were documented by pictures and the experimental light was measured on location using portable photometers...

The mechanisms of skin breakdown induced by incontinence have been proposed from a variety of experimental studies. However, studies on the influence of skin properties caused by incontinence of bedridden subjects are very limited. This work was conducted to reveal how incontinence influences skin properties by comparing bedridden incontinent elderly subjects with age-matched healthy continent elderly and middle-aged subjects. Bedridden incontinent elderly subjects (n = 35, 83.5 ± 9.7 years, mean age ± SD), healthy continent elderly (n = 41, 75.9 ± 5.6 years), and middle-aged (n = 20, 41.3 ± 2.8 years) were recruited for this study. Skin surface pH, capacitance/hydration, transepidermal water loss, and bacteria on forearm and buttock skin were measured. Hydration and transepidermal water loss values between healthy elderly subjects and incontinent elderly subjects were significantly different on buttock skin. Significant differences between those two groups were also observed regarding pH and total bacteria levels on buttock skin. The forearm skin showed no significant difference in these parameters. No significant influence was observed between with and without urination at the measurement time except for the pH of buttock skin. No significant correlation was observed except between pH and bacteria levels on buttock skin of incontinent elderly subjects. In this study, we clarified the characteristic features of skin induced by incontinence. Our results indicate that these parameters are adequate not only to evaluate the characteristic skin features of bedridden incontinent subjects but also to develop new diapers to avoid the diaper dermatitis caused by incontinence. © 2015 The International Society of Dermatology.

Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns. Nutrition is a fundamental determinant of both health and disease and its role in extending a healthy lifespan is the object of considerable research. Notably, malnutrition is one of the main threats to health and quality of life among the elderly. Therefore, knowledge about nutritional status among the elderly is essential for the promotion and maintenance of healthy ageing and to support the development of health protection policies and equity in elderly health care. This is a nationwide nutrition survey of the Portuguese population over 65 years old, with data collection through face-to-face interviews. A representative and random sample of community dwelling elderly and nursing homes residents will be obtained by multistage sampling stratified per main Portuguese regions, sex and age groups. Minimum sample size was estimated to be 2077 elderly (979 in the community and 1098 in nursing homes). Data will be collected on food habits and eating patterns, nutritional status, food insecurity, lifestyle, self-rated general health status and self-reported diseases, functionality, loneliness, cognitive function, emotional status and demographic and socio-economic characterization. This is the first national survey to evaluate the prevalence of nutritional risk and malnutrition of the Portuguese population above 65 years old, including those living in nursing homes. It will allow the identification of population subgroups of elderly with increased odds of malnutrition and nutritional risk. In addition, this survey will contribute to the identification of psychosocial and clinical predictors of malnutrition among elderly, which is an important risk factor for other

Men and women are known to react differently to stress. Thus, stress cardiomyopathy almost solely strikes women. Stress cardiomyopathy is suggested to relate to sex differences in catecholamine reaction. Left heart function during dobutamine stress is well described, but sex-specific inotropic...... and lusitropic response to abrupt termination of dobutamine stress is not. We aimed to investigate sex differences in left ventricular (LV) and atrial (LA) function during and after dobutamine stress. We enrolled 20 healthy elderly subjects (60-70 yr, 10 females) and measured their LV and LA volumes throughout......, and conduit volumes. Sex differences were not observed at rest or during dobutamine stress. Compared with prestress values, at T15 a rebound decrease in LV peak filling rate was observed in women (-22 ± 3%, P...

Full Text Available Objectives: Postural control in elderly people is impaired by degradations of sensory, motor, and higher-level adaptive mechanisms. Here, we characterize the effects of a progressive balance training program on these postural control impairments using a brain network model based on system identification techniques.Methods and Material: We analyzed postural control of 35 healthy elderly subjects and compared findings to data from 35 healthy young volunteers. Eighteen elderly subjects performed a 10 week balance training conducted twice per week. Balance training was carried out in static and dynamic movement states, on support surfaces with different elastic compliances, under different visual conditions and motor tasks. Postural control was characterized by spontaneous sway and postural reactions to pseudorandom anterior-posterior tilts of the support surface. Data were interpreted using a parameter identification procedure based on a brain network model.Results: With balance training, the elderly subjects significantly reduced their overly large postural reactions and approximated those of younger subjects. Less significant differences between elderly and young subjects' postural control, namely larger spontaneous sway amplitudes, velocities, and frequencies, larger overall time delays and a weaker motor feedback compared to young subjects were not significantly affected by the balance training.Conclusion: Balance training reduced overactive proprioceptive feedback and restored vestibular orientation in elderly. Based on the assumption of a linear deterioration of postural control across the life span, the training effect can be extrapolated as a juvenescence of 10 years. This study points to a considerable benefit of a continuous balance training in elderly, even without any sensorimotor deficits.

The purposes of this study were to determine anaerobic threshold (AT) during discontinuous dynamic and resistive exercise protocols by analysing of heart rate variability (HRV) and blood lactate (BL) in healthy elderly subjects and compare the cardiovascular, metabolic and autonomic variables obtained from these two forms of exercise. Fourteen elderly (70 ± 4 years) apparently healthy males underwent the following tests: (i) incremental ramp test on cycle ergometer, (ii) one repetition maximum (1RM) leg press at 45°, (iii) a discontinuous exercise test on a cycle ergometer (DET-C) protocol and (iv) a resistance exercise leg press (DET-L) protocol. Heart rate, blood pressure and BL were obtained during each increment of exercise intensity. No significant differences (P>0·05) were found between methods of AT determination (BL and HRV) nor the relative intensity corresponding to AT (30% of maximum intensity) between the types of exercise (DET-C and DET-L). Furthermore, no significant differences (P>0·05) were found between the DET-C and DET-L in relation to HRV, however, the DET-L provided higher values of systolic blood pressure and BL (Presistive exercise protocols were similar when compared at the same relative intensity. However, DET-L resulted in higher values of blood pressure and BL at workloads beyond AT. © 2013 Scandinavian Society of Clinical Physiology and Nuclear Medicine. Published by John Wiley & Sons Ltd.

Full Text Available BACKGROUND: This study aimed to compare Iranian elderly with the youth and middle aged population in terms of the prevalence of metabolic syndrome and its components in Iranian elderly METHODS: This cross-sectional study was conducted using the information from the third phase of Isfahan Healthy Heart Program. Male and female residents of Isfahan who aged over 19 years were selected by multistage cluster random sampling. A questionnaire including demographic characteristics, health status, medical history, medications used, as well as waist circumference, weight, height and systolic and diastolic blood pressures was completed for all participants. Fasting blood samples were obtained from all subjects and examined for fasting blood sugar and lipid profile. RESULTS: The prevalence of metabolic syndrome in individuals aged over 60 years was significantly higher than those under 60 (49.5% vs. 17.5%, respectively; P < 0.001. It was also more prevalent among elderly females than in males (59.2% vs. 39.8%, respectively; P < 0.005. Some anthropometric measures such as height, body mass index, abdominal circumference, waist-hip ratio, and waist to height ratio were significantly different in men and women below 60 years in comparison with those over 60 years (P < 0.05. Moreover, there were significant differences in most studied parameters between the elderly and non-elderly women (P < 0.001. Based on the findings of this study, the risk factors for cardiovascular diseases were significantly more prevalent in men and women over 60 years. T-test and Mann-Whitney were used for quantitative data and the square-chi test is performed for qualitative data.    CONCLUSION: This study showed that metabolic syndrome has a relatively high prevalence in Iranian elderly people (especially in women. Therefore, early diagnosis and management of the complication are recommended among this high-risk group. Keywords: Metabolic Syndrome, Elderly, Iran

To ensure the well-being of a rapidly growing elderly population, it is fundamental to find strategies to foster healthy brain aging. With this intention, we designed a program of scientific-based lectures aimed at dissemination by established neuroscientists about brain function, brain plasticity and how lifestyle influences the brain. We also carried out a pilot study on the impact of the lectures on attendees. The objective was to provide information to elderly people in order to encourage them to identify unhealthy and healthy daily habits, and more importantly, to promote behavioral changes towards healthy brain aging. Here we report on our experience. In order to determine the impact of the lectures in the daily routine of the attendees, we asked them to fill out questionnaires. Preliminary results indicate that neuroscientific information-based strategies can be a useful method to have a positive impact on the lives of elderly, increase their awareness on how to improve brain function and promote positive lifestyle modifications. Furthermore, based on self-reported data, we also found that through this strategy it is possible to promote behavioral changes related to nutrition, sleep, and realization of physical and cognitively stimulating activities. Finally, based on the results obtained, the importance of promoting self-efficacy and the empowerment of the older populations is highlighted.

Rey's Auditory Verbal Learning Test (RAVLT) is a widely used neuropsychological test to assess episodic memory. In the present study we sought to establish normative and discriminative validity data for the RAVLT in the elderly population using previously adapted learning lists for the Greek adult population. We administered the test to 258 cognitively healthy elderly participants, aged 60-89 years, and two patient groups (192 with amnestic mild cognitive impairment, aMCI, and 65 with Alzheimer's disease, AD). From the statistical analyses, we found that age and education contributed significantly to most trials of the RAVLT, whereas the influence of gender was not significant. Younger elderly participants with higher education outperformed the older elderly with lower education levels. Moreover, both clinical groups performed significantly worse on most RAVLT trials and composite measures than matched cognitively healthy controls. Furthermore, the AD group performed more poorly than the aMCI group on most RAVLT variables. Receiver operating characteristic (ROC) analysis was used to examine the utility of the RAVLT trials to discriminate cognitively healthy controls from aMCI and AD patients. Area under the curve (AUC), an index of effect size, showed that most of the RAVLT measures (individual and composite) included in this study adequately differentiated between the performance of healthy elders and aMCI/AD patients. We also provide cutoff scores in discriminating cognitively healthy controls from aMCI and AD patients, based on the sensitivity and specificity of the prescribed scores. Moreover, we present age- and education-specific normative data for individual and composite scores for the Greek adapted RAVLT in elderly subjects aged between 60 and 89 years for use in clinical and research settings.

Apathy is defined as a syndrome of primary loss of motivation not attributable to emotional distress, intellectual impairment or consciousness disturbance. The aim of our study was to investigate the effects of vascular risk factors and silent ischemic brain lesions on apathetic behavior of community-dwelling elderly subjects. Brain MRI and other medical examinations were performed on 222 non-demented community-dwelling elderly subjects (96 men and 126 women, average age 70.1 years). The apathy group was defined as the most apathetic quintile determined by Starkstein's apathy scale. Silent infarction, deep white matter lesions (DWMLs) and periventricular hyperintensities were detected in 12.2, 39.2 and 22.5%, respectively. Linear regression analysis (Pearson) revealed that the scores on the apathy scale correlated slightly but significantly with logarithmically transformed scores of the Modified Stroop Test (r=0.135, P=0.045), but not with the Mini-Mental State Examination. The apathy group tended to have more high blood pressure (141.6/82.6 vs. 136.1/79.6 mmHg), less prevalent hyperlipidemia (18 vs. 35%) and lower serum albumin. Multivariate analysis (the forward stepwise method of logistic analysis) revealed an independent correlation between the apathy and grade of DWMLs (odds ratio 1.826, 95% confidence interval (CI) 1.129-2.953 per grade) or diastolic blood pressure (DBP) (odds ratio 1.055, 95% CI 1.0 14-1.098 per mmHg) after adjusting for possible confounders. The mean apathy scale score in the DBP≥90 mmHg group was significantly lower (more apathetic) than that in the DBP<80 group (P=0.011, analysis of covariance). This study showed that hypertension and DWMLs are independently associated with apathy in healthy elderly subjects. (author)

The objective of this work was to characterize the safety, tolerability and pharmacokinetics of ABT-288, a highly selective histamine H3 receptor antagonist, in healthy young adults and elderly subjects following single and multiple dosing in a phase 1 setting. Single doses (0.1, 0.3, 1, 3, 10, 20 and 40 mg ABT-288) and multiple doses (0.5, 1.5, 3 and 6 mg ABT-288 once-daily for 14 days) were evaluated in young adults and multiple doses (0.5, 1.5, 3 and 5 mg ABT-288 once-daily for 12 days) were evaluated in elderly subjects using randomized, double-blind, placebo-controlled, dose-escalating study designs. The effect of food on ABT-288 pharmacokinetics (5 mg single dose) was evaluated using an open label, randomized, crossover design. ABT-288 safety, tolerability and pharmacokinetics were comparable in young and elderly subjects. Single doses up to 40 mg and multiple doses up to 3 mg once-daily were generally safe and well tolerated. The most frequently reported adverse events were hot flush, headache, abnormal dreams, insomnia, nausea and dizziness. ABT-288 exposure (AUC) was dose-proportional over the evaluated dose ranges. The mean elimination half-life ranged from 40 to 61 h across dose groups. Steady state was achieved by day 10 of once-daily dosing with 3.4- to 4.2-fold accumulation. Food did not have a clinically meaningful effect on ABT-288 exposure. Based on the above results, 1 and 3 mg once-daily doses of ABT-288 were advanced to phase 2 evaluation in Alzheimer's patients. © 2012 Abbott Laboratories.

Researchers speculate that depression tends to be more prevalent among immigrant elders due to their lack of resources, acculturation stress, language problems, and social isolation. However, other characteristics of elderly immigrants, such as the healthy immigrant effect, may counteract these potential risk factors. This study examined whether depressive symptoms differed between Chinese immigrant elders and their counterparts in China and whether health conditions were similarly associated with depressive symptoms in these two samples. Depression and health information was collected from 177 Chinese immigrant elders in Boston, the US in 2000 and from 428 education and gender-matched elders in Shanghai, China in 2003. Chinese immigrants had a significantly lower score on the modified Center for Epidemiologic Studies Depression Scale (CES-D) and its subscales: somatic symptoms and depressive affect. The association remained for the subscale depressive affect in multivariate analyses. Arthritis and back or neck problems were associated with a higher level of depressive symptoms among Chinese immigrants, while problems in walking were associated with depression among their counterparts in China. Pain was an underlying contributor to the association between depression and these health problems in both the groups. This study suggests that Chinese immigrant elders might be more resilient than their counterparts despite many challenges they face after moving abroad. With the growing number of older Chinese immigrants in the US, a better understanding of depressive symptoms is essential to provide culturally competent services to better serve this population.

The prevalence of monoclonal gammopathy of undetermined significance (MGUS), a premalignant plasma-cell disorder has not been determined in our geographic area Nigeria. A cross sectional survey was carried on apparently healthy Nigerians selected by multistage sampling technique from the cosmopolitan city of Lagos, Nigeria. Subjects enrolled into the study had 2-step screening for the presence, type and concentration of monoclonal band. Agarose-gel electrophoresis was performed on all serum samples, and any serum sample with a discrete band of monoclonal protein or thought to have a localized band was subjected to Immunofixation. Subjects were also evaluated for Bence jones proteinuria, haematological and biochemical parameters. Four hundred and ten subjects with a mean age of 45.68 ± 10.3 years, a median of 45.00 years and a range of 20 to 80 years were enrolled into the study. MGUS was identified in only one (0.24 percent) of the 410 study subject. This subject was demonstrated to have a double monoclonal gammopathy; IgGλ at 16.9 g/L and IgAκ at 8.5 g/L. None of them including the sole subject with MGUS had a monoclonal urinary light chain. Among residents of Lagos, Nigeria, MGUS was found in only 0.24% percent of apparently normal persons with a median age of 45 years. This suggests that MGUS which represents the earliest stage of monoclonal plasma/lymphoid cell proliferation is not a common finding in the relatively young population of Nigeria. Future epidemiologic studies dealing with plasma cell disorders in older people are required to carefully examine the relationship between environmental factors and prevalence of MGUS and its ultimate progression to MM.

Singapore's elderly population has been growing rapidly and is expected to constitute more than 25 percent of the total population by the year 2030. The ageing process brings with it a host of health problems. Here the question arises--Are the increasing years of life going to create a high proportion of sick and disabled elderly people, or a rich human resource of healthy senior citizens? Since more women are living longer than men, who would face a higher risk of disability and handicap? These questions are yet to be answered in Singapore. This paper seeks answers to these questions. The study is based on a sample survey of 1209 elderly Singaporeans living in Kampong Glam, Kreta Ayer and Bukit Merah parliamentary constituencies which have some of the highest proportions of the aged population. The results revealed that more than half of the aged had a disability and the rate of disability was significantly higher among the women as compared to the men. More than one-third of the elderly had a handicap and the rate of handicap among the women was twice as much as that among the men. Severity of handicap was directly correlated with age.

Scope: Theobromine is a major active compound in cocoa with allegedly beneficial effect on high-density-lipoprotein-cholesterol (HDL-CH). We have investigated the effect of theobromine (TB) consumption on the concentrations of triglyceride (TG) and cholesterol (CH) in various lipoprotein (LP) subclasses. Methods: In a randomized, double-blind, placebo-controlled, cross-over study, 44 apparently healthy women and men (age: 60 ± 6 years, BMI: 29 ± 3 kg/m 2 ) with low baseline HDL-CH concentrations consumed a drink supplemented with 500 mg/d theobromine for 4 weeks. TG and CH concentrations in 15 LP subclasses were predicted from diffusion-edited 1 H NMR spectra of fasting serum. Results: The LP phenotype of the subjects was characterized by low CH concentrations in the large HDL particles and high TG concentrations in large VLDL and chylomicron (CM) particles, which clearly differed from a LP phenotype of subjects with normal HDL-CH. TB only reduced CH concentrations in the LDL particles by 3.64 and 6.79%, but had no effect on TG and CH in any of the HDL, VLDL and CM subclasses. Conclusion: TB was not effective on HDL-CH in subjects with a LP phenotype characterized by low HDL-CH and high TG in VLDL.

Full Text Available Oral care is important to decrease oral bacteria, especially in the dependent elders. There have been some reports on oral microflora in the dependent elders. However, investigations involving healthy independent elders are limited. The purpose of this study was to obtain more information on the microflora in Japanese independent elders. One hundred Japanese independent elders aged 65 years or older participated in this study. Eighty-one independent elders (male: 44, female: 37, mean age: 72.7 ± 5.8 participated in this study. Their mean Barthel Index was 99.1 ± 3.1, and mean score of MMSE was 28.0 ± 2.3. The tongue bacterial flora was examinved to identify microorganisms by the culture method. The predominant aerobic organisms were Streptococcus spp. (detection rate: 100%, Neisseria spp. (96%, and Corynebacterium spp. (56%. Candida spp. was also isolated (32%. In this study, the oral microflora of the tongue in Japanese independent elders was clarified. The results of this investigation may contribute to research on oral bacteria in elder persons in the future.

As centenarians well represent the model of healthy aging, there are many important implications in revealing the underlying molecular mechanisms behind such successful aging. By combining NMR metabonomics and shot-gun lipidomics in serum we analyzed metabolome and lipidome composition of a group of centenarians with respect to elderly individuals. Specifically, NMR metabonomics profiling of serum revealed that centenarians are characterized by a metabolic phenotype distinct from that of elderly subjects, in particular regarding amino acids and lipid species. Shot- gun lipidomics approach displays unique changes in lipids biosynthesis in centenarians, with 41 differently abundant lipid species with respect to elderly subjects. These findings reveal phospho/sphingolipids as putative markers and biological modulators of healthy aging, in humans. Considering the particular actions of these metabolites, these data are suggestive of a better counteractive antioxidant capacity and a well-developed membrane lipid remodelling process in the healthy aging phenotype.

2014-12-01

The increasing average life expectancy is simultaneously increasing the incidence of chronic diseases and the number of healthy elderly people, consequently leading to an increased demand for healthcare management methods that do not involve hospital visits. The development of health management services involving mobile phones will change the focus of medical services from hospital visits and treatments to managing the health decisions made by individuals in their daily lives. However, the elderly may experience specific difficulties in adapting to constantly evolving services. This study reviews various health-related devices such as mobile phones that are available for providing healthcare to the elderly, and the different ways of using them. As the use of mobile phone increases, it is expected that elderly mobile phone users will also be able to regularly check their health status at any time and place. The issues of an ageing population pertain to the entire society rather than only to the elderly, which make mobile-phone-based medical informatics as a health management service a worthy goal.

Vector-borne pathogens (VBPs) are a group of globally extended and quickly spreading pathogens that are transmitted by various arthropod vectors. The aim of the present study was to investigate the seroprevalence against Babesia canis, Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, Leishmania infantum, Dirofilaria immitis, and Ehrlichia canis in dogs in Croatia. We investigated 435 randomly selected apparently healthy dogs in 13 different locations of Croatia for antibodies to B. canis by indirect immunofluorescence using a commercial IFA IgG Antibody Kit. All samples were also tested for qualitative detection of D. immitis antigen and for antibodies to A. phagocytophilum, B. burgdorferi sensu lato, L. infantum, and E. canis with two point-of-care assays. Overall, 112 dogs (25.74%, 95% confidence interval [CI] 21.70-30.12) were serologically positive for one or more of the pathogens. B. canis was the most prevalent pathogen (20.00%, 95% CI 16.34-24.07), followed by A. phagocytophilum (6.21%, 95% CI 4.12-8.90), L. infantum, (1.38%, 95% CI 0.51-2.97), and B. burgdorferi sensu lato (0.69%, 95% CI 0.01-2.00). The lowest seroprevalence was for D. immitis and E. canis (0.46%, 95% CI 0.01-1.65). Coinfection was determined in 12 dogs (2.76%, 95% CI 1.43-4.77), of which 10 were positive to two pathogens (7 with B. canis and A. phagocytophilum and 1 B. canis with B. burgdorferi sensu lato or L. infantum or E. canis). One dog was positive to three pathogens and another dog to four pathogens. Seroprevalence for babesia was age, breed, and lifestyle/use dependent. Purebred dogs had almost half the chance of developing disease than crossbred (OR = 0.58, p Croatia. Some of these VBPs are zoonotic and represent a potential risk to public health.

The aim of our investigation was to compare the BAEP results of this group with those of healthy controls with presbycusis and to look for possible correlations between alteration of the auditory brainstem function and the aging of elderly diabetic patients. Absolute and interpeak latencies of all waves were prolonged significantly in the study group of diabetic patients. The amplitudes of all waves I through V were diminished in the study group as compared to those in the control group, with statistical significance present for all waves. Analysis of the latencies (waves I, II, I, and V), interpeak latencies (I-V), and amplitudes (I, II, III, and V) of BAEP revealed a significant difference between those of diabetics and those of healthy elderly controls with presbycusis. These data support a hypothesis that there is a brainstem neuropathy in diabetes mellitus that can be assessed with auditory brainstem response testing even in the group of elderly patients with sensorineural hearing loss.

Full Text Available OBJECTIVES: The objective of the study was to mesaure the 12-months prevalence of elder abuse and neglect in private huousehold and to examine the relationship and community level risk factors for elder abuse and neglect. METHOD: Total of 960 respondents aged 65 years and above in private households, from all eight statistical regions participated in the study.  Nationally stratified quota sampling procedure was applied, through four stages. Information was collected in face-to face interview on socio-demographic, healthy life style, physical and mental health, and abuse and neglect types characteristics of elder population. Data were examined using descriptive statistics, binary logistic regression, and odd ratios (OR. Statistical significance was set up at p < 0.05. RESULTS: The respondents reported prevalence of psychological abuse 25.7%, followed by financial abuse 12 %, neglect 6.6%, physical abuse 5.7%, physical injury 3.1%, and sexual abuse 1.3% (reported only in female respondents in the previous 12-months. Living with close relatives, dissatisfaction with the household income, less equipped households, lacking property of house/flat are associated risk factors for elder maltreatment on relationship level. Living in the northeast, southeast, and Polog region are associated risk for elder maltreatment. CONCLUSION: Study findings emphasised the previous data obtained with regards to the community and relationships risk factors for elder maltreatment.

Full Text Available Abstract Background The prevalence of monoclonal gammopathy of undetermined significance (MGUS, a premalignant plasma-cell disorder has not been determined in our geographic area Nigeria. Methods A cross sectional survey was carried on apparently healthy Nigerians selected by multistage sampling technique from the cosmopolitan city of Lagos, Nigeria. Subjects enrolled into the study had 2-step screening for the presence, type and concentration of monoclonal band. Agarose-gel electrophoresis was performed on all serum samples, and any serum sample with a discrete band of monoclonal protein or thought to have a localized band was subjected to Immunofixation. Subjects were also evaluated for Bence jones proteinuria, haematological and biochemical parameters. Results Four hundred and ten subjects with a mean age of 45.68 ± 10.3 years, a median of 45.00 years and a range of 20 to 80 years were enrolled into the study. MGUS was identified in only one (0.24 percent of the 410 study subject. This subject was demonstrated to have a double monoclonal gammopathy; IgGλ at 16.9 g/L and IgAκ at 8.5 g/L. None of them including the sole subject with MGUS had a monoclonal urinary light chain. Conclusion Among residents of Lagos, Nigeria, MGUS was found in only 0.24% percent of apparently normal persons with a median age of 45 years. This suggests that MGUS which represents the earliest stage of monoclonal plasma/lymphoid cell proliferation is not a common finding in the relatively young population of Nigeria. Future epidemiologic studies dealing with plasma cell disorders in older people are required to carefully examine the relationship between environmental factors and prevalence of MGUS and its ultimate progression to MM.

Memory is impaired in schizophrenia patients but it is not clear whether this is specific to the illness and whether different types of memory (verbal and nonverbal) or memories in different cognitive domains (executive, object recognition) are similarly affected. To study relationships between memory impairments and schizophrenia we compared memory functions in 77 schizophrenia patients, 58 elderly healthy individuals and 41 young healthy individuals. Tests included verbal associative and logical memory and memory in executive and object recognition domains. We compared relationships of memory functions to each other and to other cognitive functions including psychomotor speed and verbal and spatial working memory. Compared to the young healthy group, schizophrenia patients and elderly healthy individuals showed similar severe impairment in logical memory and in the ability to learn new associations (NAL), and similar but less severe impairment in spatial working memory and executive and object memory. Verbal working memory was significantly more impaired in schizophrenia patients than in the healthy elderly. Verbal episodic memory impairment in schizophrenia may share common mechanisms with similar impairment in healthy aging. Impairment in verbal working memory in contrast may reflect mechanisms specific to schizophrenia. Study of verbal explicit memory impairment tapped by the NAL index may advance understanding of abnormal hippocampus dependent mechanisms common to schizophrenia and aging.

We investigated the severity of andropausal and depressive symptoms, as well as their hormonal determinants, in 196 middle-aged and elderly men (age range: 40–80 years with prediabetes (PD and in 184 healthy peers. PD was diagnosed according to the definition of the American Diabetes Association. The severity of andropausal and depressive symptoms was assessed using the Aging Males’ Symptoms Rating Scale and the Self-Rating Depression Scale. Total testosterone (TT, calculated free testosterone (cFT, dehydroepiandrosterone sulfate (DHEAS, and insulin-like growth factor 1 (IGF-1 were measured. The prevalence of andropausal syndrome in men with PD was significantly higher than that in healthy men (35% vs 11%, respectively. In men with PD aged 40–59 years, the severity of sexual, psychological, and all andropausal symptoms was greater than in healthy peers, while in elderly men (60–80 years, only the severity of psychological symptoms was greater than in healthy peers. The severity of depressive symptoms in the middle-aged men with PD was greater than in healthy peers, while the severity of depressive symptoms in elderly men with PD and healthy peers was similar. The higher prevalence of andropausal symptoms was independently associated with cFT and IGF-1 in middle-aged men and with TT and DHEAS in elderly men with PD. The more severe depression symptoms were associated with low TT and DHEAS in middle-aged men and with low cFT and DHEAS in elderly men with PD. In conclusion, the prevalence of andropausal symptoms, especially psychological, was higher in prediabetic

Full Text Available XinQi Dong Rush Institute for Healthy Aging, Rush University Medical Center, Chicago, IL, USA Abstract: Elder self-neglect is a global public health and human rights issue that threatens older people’s health and safety. It commonly refers to refusal or failure to provide oneself with care and protection in areas of food, water, clothing, hygiene, medication, living environments, and safety precautions. While prevalent, the status of self-neglecting individuals remains largely unclear, in particular within community-dwelling populations. By reviewing the epidemiology of elder self-neglect (definition, prevalence, risk factors, and consequences to date, the present paper identifies key research gaps such as methodological inconsistency in case identification and measurement, and study designs that are inadequate to determine risk factors of self-neglect. More importantly, in light of the rapidly growing older population, relevant stakeholders (researchers, healthcare providers, social service providers, legal professionals, community organizations, and policymakers must be prepared for an expected increasing number of self-neglect cases and enlarging scope of the problem. Hence, in this article, I present an overview regarding the management issues of elderly self-neglect related to the detection, assessment, reporting and referral, and decision-making capacity. Based on the current literature, the paper is aimed to explore the present knowledge and challenges, and how they can pave the way for solutions to self-neglect research, practice, and policy.

Socially assistive robotics for elderly care is a growing field. However, although robotics has the potential to support elderly in daily tasks by offering specific services, the development of usable interfaces is still a challenge. Since several factors such as age or disease-related changes in perceptual or cognitive abilities and familiarity with computer technologies influence technology use they must be considered when designing interfaces for these users. This paper presents findings from usability testing of two different services provided by a social assistive robot intended for elderly with cognitive impairment: a grocery shopping list and an agenda application. The main goal of this study is to identify the usability problems of the robot interface for target end-users as well as to isolate the human factors that affect the use of the technology by elderly. Socio-demographic characteristics and computer experience were examined as factors that could have an influence on task performance. A group of 11 elderly persons with Mild Cognitive Impairment and a group of 11 cognitively healthy elderly individuals took part in this study. Performance measures (task completion time and number of errors) were collected. Cognitive profile, age and computer experience were found to impact task performance. Participants with cognitive impairment achieved the tasks committing more errors than cognitively healthy elderly. Instead younger participants and those with previous computer experience were faster at completing the tasks confirming previous findings in the literature. The overall results suggested that interfaces and contents of the services assessed were usable by older adults with cognitive impairment. However, some usability problems were identified and should be addressed to better meet the needs and capacities of target end-users.

Hypertriglyceridemic waist phenotype is a simple screening parameter to identify people at increased risk for cardiovascular disease. We evaluated whether hypertriglyceridemic waist (HTGW) phenotype increases the risk for coronary artery calcification (CAC) in apparently healthy Korean adults. A total of 32,186 participants (mean age 41.3, 80.2% men) in a health screening program, in whom the coronary artery calcium score (CACS) was measured, were analyzed. Subjects were divided into four groups: 1) normal waist circumference (WC)-normal triglyceride (TG) (NWNT), 2) normal WC-high TG (NWHT), 3) enlarged WC-normal TG (EWNT), and 4) enlarged WC-high TG (EWHT). Enlarged WC was defined as WC ≥ 90 cm for men and ≥ 85 cm for women; high serum TG was defined as TG ≥ 150 mg/dL. The presence of CAC was defined by CACS >0, and CACS was analyzed in a logarithmized form of CACS plus 1 {ln(CACS+1)}. A total of 14.9% of the participants had CAC. The EWHT group showed the highest mean value for ln(CACS+1) among the four groups. The EWHT group showed the highest odds ratio for CAC, with NWHT group the second, and with EWNT group the third compared with the NWNT group after adjusting for confounding variables (1.579, 1.302, and 1.266 vs. NWNT). The EWHT group showed the highest association for CAC, suggesting this HTGW phenotype as a useful marker for the detection of subjects with high cardiometabolic risk in healthy Korean adults.

Recent evidence suggests that the sleep-dependent consolidation of declarative memory relies on the nonrapid eye movement rather than the rapid eye movement phase of sleep. In addition, it is known that aging is accompanied by changes in sleep and memory processes. Hence, the purpose of this study was to investigate the overnight consolidation of declarative memory in healthy elderly women. Sleep laboratory of University. Nineteen healthy elderly women (age range: 61-74 years). We used laboratory-based measures of sleep. To test declarative memory, the Rey-Osterrieth Complex Figure Test was performed. Declarative memory performance in elderly women was associated with Stage 2 sleep spindle density. Women characterized by high memory performance exhibited significantly higher numbers of sleep spindles and higher spindle density compared with women with generally low memory performance. The data strongly support theories suggesting a link between sleep spindle activity and declarative memory consolidation.

Erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) are common in diabetic men. The aim of this study was to investigate hormonal determinants, the prevalence and severity of ED and LUTS in middle-aged and elderly men with prediabetes (PD). We investigated 176 men with PD and 184 healthy peers. PD was defined according American Diabetes Association. ED according IIEF scale and LUTS according IPSS scale were assessed. Total testosterone (TT), calculated free testosterone (cFT), dehydroepiandrosterone sulfate (DHEAS) and insulin-like growth factor 1 (IGF-1) were measured. The prevalence of ED in patients with PD was higher than in control group (30 versus 24%) as well as the prevalence and severity of ED and LUTS in elderly (60-80 years) and middle-aged (40-59 years) men with PD was higher than in healthy peers. In middle-aged pre-diabetic men, the more severe LUTS symptoms were associated with low TT and DHEAS, while in elderly men with low cFT and DHEAS. The higher prevalence of ED in middle-aged men with PD was associated with cFT and DHEAS, while in elderly pre-diabetic men with TT and IGF-1. The prevalence and severity of LUTS and ED symptoms were higher in pre-diabetic men than in healthy peers. Hormonal determinants of these symptoms are different in middle-aged and elderly patients with PD.

The Old-Age Healthy Dependency Ratio in Europe.

Muszyńska, Magdalena M; Rau, Roland

2012-09-01

The aim of this study is to answer the question of whether improvements in the health of the elderly in European countries could compensate for population ageing on the supply side of the labour market. We propose a state-of-health-specific (additive) decomposition of the old-age dependency ratio into an old-age healthy dependency ratio and an old-age unhealthy dependency ratio in order to participate in a discussion of the significance of changes in population health to compensate for the ageing of the labour force. Applying the proposed indicators to the Eurostat's population projection for the years 2010-2050, and assuming there will be equal improvements in life expectancy and healthy life expectancy at birth, we discuss various scenarios concerning future of the European labour force. While improvements in population health are anticipated during the years 2010-2050, the growth in the number of elderly people in Europe may be expected to lead to a rise in both healthy and unhealthy dependency ratios. The healthy dependency ratio is, however, projected to make up the greater part of the old-age dependency ratio. In the European countries in 2006, the value of the old-age dependency ratio was 25. But in the year 2050, with a positive migration balance over the years 2010-2050, there would be 18 elderly people in poor health plus 34 in good health per 100 people in the current working age range of 15-64. In the scenarios developed in this study, we demonstrate that improvements in health and progress in preventing disability will not, by themselves, compensate for the ageing of the workforce. However, coupled with a positive migration balance, at the level and with the age structure assumed in the Eurostat's population projections, these developments could ease the effect of population ageing on the supply side of the European labour market.

Full Text Available Background: Arterial stiffness reflects the ageing processes in the vascular system, and studies have shown an association between reduced cognitive function and cerebral small vessel disease. Small vessel disease can be visualized as white matter hyperintensities (WMH and lacunar infarcts but also as cerebral microbleeds on brain magnetic resonance imaging (MRI. We aimed to investigate if arterial stiffness influences the presence of microbleeds, WMH and cognitive function in a population of cognitively healthy elderly. Methods: The study population is part of the Swedish BioFinder study and consisted of 208 individuals without any symptoms of cognitive impairment, who scored >27 points on the Mini-Mental State Examination. The participants (mean age, 72 years; 59% women underwent MRI of the brain with visual rating of microbleeds and WMH. Arterial stiffness was measured with carotid-femoral pulse wave velocity (cfPWV. Eight cognitive tests covering different cognitive domains were performed. Results: Microbleeds were detected in 12% and WMH in 31% of the participants. Mean (±standard deviation, SD cfPWV was 10.0 (±2.0 m/s. There was no association between the presence of microbleeds and arterial stiffness. There was a positive association between arterial stiffness and WMH independent of age or sex (odds ratio, 1.58; 95% confidence interval, 1.04-2.40, p 0.05. Cognitive performance was not associated with microbleeds, but individuals with WMH performed slightly worse than those without WMH on the Symbol Digit Modalities Test (mean ± SD, 35 ± 7.8 vs. 39 ± 8.1, p Conclusions: Arterial stiffness was not associated with the presence of cerebral microbleeds or cognitive function in cognitively healthy elderly. However, arterial stiffness was related to the presence of WMH, but the association was attenuated when multiple adjustments were made. There was a weak negative association between WMH and performance in one specific test of attention

BACKGROUND AND OBJECTIVES: The combination of cromolyn and ibuprofen is being investigated as a treatment for early Alzheimer's disease (AD). This study investigated the pharmacokinetics, safety, and tolerability of cromolyn and ibuprofen co-administration in healthy elderly adult volunteers. In this open-labeled study, 26 subjects, aged 55-75 years, received co-administration of inhaled cromolyn (single dose 17.1 mg; double dose 34.2 mg total) and oral ibuprofen (single dose 10 mg; double dose 20 mg total). Blood sampling was performed for 6 h after co-administration in all subjects; cerebrospinal fluid (CSF) was collected in three to four subjects per cohort for 4 h following co-administration. Safety parameters, including adverse events (AEs), were monitored throughout the study. For cromolyn, the mean (±SD) maximum observed concentration (C max ) in plasma was 46.69 ± 32.97 and 96.75 ± 46.22 ng/ml after single- and double-dose inhalation, respectively [time to C max (t max ) ~22 min for each; terminal elimination half-life (t ½ ) ~1.8 h for each]. For ibuprofen, the plasma C max was 1090.98 ± 474.64 ng/ml and 2062.96 ± 655.13 ng/ml after single- and double-dose oral administration, respectively (t max ~1.6-1.8 h; t ½ ~1.9 h for each). For cromolyn, the CSF C max was 0.24 ± 0.08 ng/ml at 3.72 ± 0.70 h after single-dose administration and 0.34 ± 0.17 ng/ml at 3.45 ± 0.95 h after double-dose administration, and for ibuprofen, the CSF C max was 3.94 ± 1.29 ng/ml at 2.55 ± 0.96 h after single-dose administration and 8.93 ± 3.29 ng/ml at 3.15 ± 1.05 h after double-dose administration. Three (12%) subjects reported mild or moderate AEs which were unlikely to be related to study drug. The combination of cromolyn and ibuprofen was safe and well tolerated. The concentrations of cromolyn and ibuprofen observed in the CSF are considered sufficient to titrate the estimated daily amyloid production and the associated inflammatory response

Zinc (Zn) plays an essential role in many biological processes including immune response. Impaired Zn status promotes immune dysfunction, and it has been associated with enhanced chronic inflammation during aging. It has been suggested that the measurement of circulating Zn by itself could not reflect the real Zn status of an individual. It is therefore necessary to identify other determinants associated with plasma Zn to better understanding how physiopathological conditions during aging may affect the concentration of this metal. We have investigated the association between Zn levels and some biomarkers in 1090 healthy elderly from five European countries to increase the accuracy in the assessment of the Zn status. Stepwise multivariate linear regression models were used to analyze the influence of factors such as age, dietary intake, inflammatory mediators, laboratory parameters and polymorphisms previously associated with Zn homeostasis. Plasma Zn decrement was most strongly predicted by age, while positive correlations were found with albumin, RANTES and Zn intake after adjustment for multiple confounders. HSP70 +1267 AA genotype was an independent factor associated with Zn plasma concentrations. Cu/Zn ratio was positively associated with markers of systemic inflammation and age and negatively associated with albumin serum levels. Our findings show the most important independent determinants of plasma Zn concentration and Cu/Zn ratio variability in elderly population and suggest that the decline with age of Zn circulating levels is more dependent on physiopathological changes occurring with aging rather than to its nutritional intake.

Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

Promoting protein consumption in the elderly population may contribute to improving the quality of their later years in life. Our study aimed to explore knowledge, perceptions and preferences of elderly consumers regarding protein-enriched food. We conducted three focus groups with independently living (ID) elderly (N = 24, Mage = 67 years) and three with elderly living in a residential home (RH) (N = 18, Mage = 83 years). Both the ID and RH elderly were predominantly sceptical about functional food in general. Confusion, distrust and a perceived lack of personal relevance were main perceived barriers to purchasing and consuming these products, although a majority of the participants did report occasionally consuming at least one type of functional food. For the ID elderly, medical advice was an important facilitator that could overcome barriers to purchasing and consuming protein-enriched food, indicating the importance of personal relevance for this group. For the RH elderly, in contrast, sensory appeal of protein-enriched foods was a facilitator. Carrier preferences were similar for the two groups; the elderly preferred protein-enriched foods based on healthy products that they consumed frequently. Future studies should explore ways to deal with the confusion and distrust regarding functional food within the heterogeneous population of elderly. Copyright © 2014 Elsevier Ltd.

Cardiac and renal damage in the elderly hypertensive

2002-03-01

Full Text Available In the elderly patient with essential hypertension of long duration or de novo systolic hypertension, the prevalence of co-morbid conditions, be they apparent or not, the burden of associated diseases and the alteration in nutritional status and lifestyle, result in specific problems with regards to hypertension-related target organ damage. Accumulating data suggest that left ventricular (LV remodelling is a common finding in the nor-motensive elderly, and that LV hypertrophy (LVH will herald the development of heart failure in a fraction of patients with either systolic/diastolic or isolated systolic hypertension. Increased arterial stiffness, as well as impaired myocardial relaxation, reduced early diastolic filling and decreased ?-adrenergic responsiveness, contribute to the large prevalence of abnormalities in LV function in the elderly hypertensive. The response to exercise is clearly attenuated, and coronary heart disease, although highly prevalent, may be misdiagnosed because symptoms are altered. The elderly hypertensive is exquisitely sensitive to both volume depletion and excessive sodium intake, due to a marked sodium sensitivity of blood pressure (BP. A decline in renal blood flow and glomerular filtration rate (GFR is a common finding in the elderly. Although structural alterations attributed to age and hypertension may differ, hypertension is often looked upon as an accelerated form of ageing with regards to the heart and the kidney. Lifestyle modifications and initial monotherapy with a low-dose diuretic are warranted in the elderly hypertensive with no co-morbidity; a variety of specific approaches are considered when associated clinical conditions are present. Blockers of the renin-angiotensin system (RAS may be the preferred first-line agents in many patients with cardiac or renal damage.

Large-scale longitudinal neuroimaging studies with diffusion imaging techniques are necessary to test and validate models of white matter neurophysiological processes that change in time, both in healthy and diseased brains. The predictive power of such longitudinal models will always be limited by the reproducibility of repeated measures acquired during different sessions. At present, there is limited quantitative knowledge about the across-session reproducibility of standard diffusion metrics in 3T multi-centric studies on subjects in stable conditions, in particular when using tract based spatial statistics and with elderly people. In this study we implemented a multi-site brain diffusion protocol in 10 clinical 3T MRI sites distributed across 4 countries in Europe (Italy, Germany, France and Greece) using vendor provided sequences from Siemens (Allegra, Trio Tim, Verio, Skyra, Biograph mMR), Philips (Achieva) and GE (HDxt) scanners. We acquired DTI data (2 × 2 × 2 mm(3), b = 700 s/mm(2), 5 b0 and 30 diffusion weighted volumes) of a group of healthy stable elderly subjects (5 subjects per site) in two separate sessions at least a week apart. For each subject and session four scalar diffusion metrics were considered: fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD) and axial (AD) diffusivity. The diffusion metrics from multiple subjects and sessions at each site were aligned to their common white matter skeleton using tract-based spatial statistics. The reproducibility at each MRI site was examined by looking at group averages of absolute changes relative to the mean (%) on various parameters: i) reproducibility of the signal-to-noise ratio (SNR) of the b0 images in centrum semiovale, ii) full brain test-retest differences of the diffusion metric maps on the white matter skeleton, iii) reproducibility of the diffusion metrics on atlas-based white matter ROIs on the white matter skeleton. Despite the differences of MRI scanner

Elevated plasma homocyst(e)ine is a risk factor for cardiovascular disease (CVD) in many populations, but the relationship between homocyst(e)ine and CVD in Japanese subjects has been unclear. It has been hypothesized that the link between homocyst(e)ine and CVD may be mediated in part by activation of coagulation and endothelial cell injury in the elderly Japanese subjects. To further evaluate this hypothesis, the present cross-sectional study was designed to assess the relationships among plasma homocyst(e)ine concentrations, risk of CVD, and markers of coagulation (fibrinogen, FVII, F1+2, FVIIa and FXIIa) and endothelial cell damage (vWF and thrombomodulin) in 146 elderly Japanese subjects (79 healthy controls and 67 patients with CVD). The geometric mean (range) of plasma homocyst(e)ine concentrations was 10.2 (3.2--33) micromol/l in 79 Japanese healthy elderly subjects. As expected, healthy female and male elderly subjects had homocyst(e)ine levels that were 2.5 and 5.3 micromol/; higher, respectively, compared to healthy young control subjects (n=62). Healthy young and elderly men had homocyst(e)ine levels that were 1.7 and 4.5 micromol/l higher, respectively, compared to values in women. This higher plasma homocyst(e)ine levels in the elderly subjects were negatively correlated with levels of folic acid, albumin and total cholesterol, but were not significantly related to markers of coagulation or endothelial cell-damage. The results of multiple logistic regression analyses suggested that high homocyst(e)ine levels were independently related to CVD risk. In addition, levels of FVIIa, and F1+2 were significantly higher in elderly Japanese patients with CVD compared to elderly subjects without CVD, but were unrelated to plasma homocyst(e)ine concentrations. In summary, elevated plasma concentrations of homocyst(e)ine, FVIIa, and F1+2 were associated with increased risk of CVD in elderly male and female Japanese subjects, but the association between homocyst

Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength. It imposes significant costs on health care systems. Socioeconomic status is also the root cause of healthy challenges among the elderly. Therefore, investigating the association between sarcopenia and socioeconomic status is very important to improve healthy ageing of the elderly. The aim of this study was to investigate the prevalence of sarcopenia and its association with socioeconomic status among the elderly in Tehran. Cross-sectional and case-control studies were conducted from August 2014-July 2015 among 310 men and 334 women elderly (60 and over years old) in Tehran health centers. Randomization, restriction and matching were setting during study design to minimize selection bias. Then study participants were recruited via phone call. Participants' phone numbers were already recorded in a telephone book electronically. When there were two elderly people in the same house, only one person was invited randomly. Association between sarcopenia and socio-economic status was analyzed by SPSS version 22. The overall prevalence of sarcopenia in the elderly was 16.5%. Prevalenceamong the low-income elderly was relatively higher than (20.5%) that among those with middle income status (18.2%) while in the higher income, the proportion of sarcopenia was very low (12.8%). The findings indicated that 339(52.6%) were in low-income status, 304(47.1%) were in middle-income status and 1(.2%) in high-income class. There was a significant association between socioeconomic status and sarcopenia (P-value sarcopenia was 0.97 times more likely higher in low socioeconomic class than those who were in middle and high income classes.

Full Text Available Hepatitis C is a global health issue. Pakistan is among the prevalent countries for hepatitis C virus (HCV. Due to poverty, unemployment, low literacy rate, unawareness and poor health facilities, Pakistani population are susceptible to HCV transmission. As blood transfusion is a potential source of HCV; therefore, this study was designed to determine the recent seroprevalence of HCV among the healthy blood donors of Karachi, Pakistan. For this purpose, 536 blood donors were screened for anti- HCV antibodies by 3rd generation ELISA. The seroprevalence of HCV observed is 2.99% among healthy blood donors. Male predominance is noticed with seropositivity of 2.62%; however, only 0.37% female blood donors were reactive for anti-HCV antibodies. This study concludes that HCV frequency has been increased in the natives of Karachi, Pakistan when compared to the past studies. Therefore, it is recommended that the healthcare authorities should play a vital role in enforcing preventive measures for HCV transmission.

The feasibility of the SON-R 5 1/2-17, a non-verbal intelligence test for deaf children, was investigated in a group of older adults, with a view to the future use of the test in older neurological patients. In a group of 58 healthy elderly persons intelligence was measured with the SON, the Raven Progressive Matrices and a Dutch reading test. The subjects were also asked for their subjective judgements of the tests. The SON-R 5 1/2-17 appears to be a user-friendly test. The high correlations between the subtests, and between the SON and other measures of intelligence suggest that the SON is a valid test for measuring fluid intelligence in elderly persons. The existing norms are not suitable when the SON is used in elderly people, new norms for adults should therefore be developed.

Chronic pain in vulnerable elderly people is still poorly recognized and treated, both at home and in hospitals and care and nursing homes. Vulnerable elderly people experience and express pain differently to relatively healthy adults, especially when they suffer from cognitive impairment or specific conditions. Determining the nature and severity of the pain requires the use of pain assessment instruments that have been validated for use in vulnerable elderly people. Effective treatment of pain demands careful diagnosis and pharmacological and non-pharmacological interventions that have proven effectiveness in vulnerable elderly people. The combination of multiple morbidity and poly-pharmacy increases the chance of side-effects and complications. In addition, the pharmacokinetic and pharmacodynamic characteristics of many drugs are different in vulnerable elderly people. The advice is to start with a lower dose of pain medication and gradually build up a level on the basis of pain relief and side-effects ('start low, go slow!').

Sit-to-walk (STW) is a commonly performed activity of daily living that requires a precise coordination between momentum generation and balance control. However, there is a lack of biomechanical data demonstrating how the center of mass (COM) momentum and balance control interact. This study examines COM kinetic energy distribution in three movement directions and COM-Ankle inclination angles during STW among 15 healthy young adults, 15 elderly non-fallers, and 15 elderly fallers. We found that elderly adults, especially elderly fallers, chose a COM control strategy that provided more stability than mobility to perform STW. A smaller forward COM velocity, a more upward COM momentum distribution, and a smaller anterior-posterior COM-Ankle angle characterize this strategy. Healthy elderly adults modified their STW movement around seat-off so that they achieved a more upright position before walking. Elderly fallers not only altered COM control around seat-off but also showed limitation in COM control during gait initiation. Furthermore, their COM control in the medial-lateral direction might be perturbed at swing-off due to an increased distribution of kinetic energy. Examining COM momentum distribution in different movement directions and the relationship between positions of the COM and supporting foot during STW could enhance our ability to identify elderly adults who are at risk of falling.

The close bond between pet animals and family members poses risk of infection with zoonotic bacterial pathogens such as Salmonella. No data is available on occurrence of Salmonella in dogs in Ethiopia. The aim of this study was therefore to determine the prevalence, serotype distribution and antimicrobial resistance of Salmonella from feces of apparently healthy dogs in Addis Ababa, Ethiopia. Of the total 360 dogs examined, 42 (11.7%; 95% Confidence limit of 8.5%-15.4%) were positive for Salmonella. Fourteen serotypes were detected and the predominant ones were S. Bronx (n = 7; 16.7%), S. Newport (n = 6; 14.3%), followed by S. Typhimurium, S. Indiana, S. Kentucky, S. Saintpaul and S. Virchow (n = 4; 9.5%) each. Salmonella infection status was significantly associated with history of symptom of diarrhea during the past 60 days (OR = 3.78; CI = 1.76-8.13; p = 0). Highest resistance rates were found for oxytetracycline (59.5%), neomycin (50%), streptomycin (38.1%), cephalothin (33.3%), doxycycline (30.9%), ampicillin (30.9%) and amoxicillin + clavulanic acid (26.2%). Thirty eight (90.5%) of the isolates were resistant or intermediately resistant to at least one of the 16 antimicrobials tested. Resistance to two or more antimicrobials was detected in 30 (71.4%) of the isolates. Resistance to three or more antimicrobials was detected in 19 (45.2%) of the isolates. This study demonstrated high carriage rate of Salmonella serotypes known for causing human salmonellosis and large proportion of them were resistant to antimicrobials used in public and veterinary medicine for management of various bacterial infections, suggesting the possible risk of infection of human population in close contact with these dogs by drug resistant pathogens. Therefore, it is vital to work on raising public awareness on zoonotic canine diseases prevention measures and good hygienic practices.

Full Text Available Objective: To determine the prevalence and antimicrobial resistance profiles of Salmonella isolates in the mesenteric lymph nodes of apparently healthy slaughtered food animals at Maiduguri central abattoir, Nigeria. Methods: A total of 154 lymph nodes (cattle-54, camel-22, sheep-12, goats-66 were collected from slaughtered animals and analysed using standard microbiological and biochemical methods. Results: An overall prevalence of 39.0% [95% confidence interval (CI: 31.3–46.7] was obtained. The prevalence rate across studied species ranged from 24.2% (95% CI: 13.9–34.5 in goats to 61.1% (95% CI: 48.1–74.1 in cattle. There was statistically significant association between Salmonella infection and species of food animals (P 0.05. Younger animals had slightly higher prevalence (44.0%; 95% CI: 24.5–63.5 compared with adults (38.0%; 95% CI: 29.6–46.4 (P > 0.05. All isolates showed marked susceptibility to ciprofloxacin, cotrimoxazole and chloramphenicol. Whereas, high resistance patterns to ampicillin, kanamycin and streptomycin, and moderate resistance patterns to kanamycin and tetracycline were observed from camels. Conclusions: Salmonella is high in the mesenteric lymph nodes of apparently healthy slaughtered food animals in Maiduguri. Therefore, it is recommended that further studies should be carried out to identify the serotypes and phage typing of the isolates, and hazard analysis and critical control point should be applied in handling of meat and meat products to avoid the risk of foodborne salmonellosis as well as appropriate use of antibiotics like ciprofloxacin in food animals.

Full Text Available Introduction: Subjective memory complaints in the elderly have been suggested as an early sign of dementia. This study aims at investigating whether specific cognitive complaints are more useful than others to discriminate Mild Cognitive Impairment (MCI by examining the dimensional structure of the Everyday Memory Questionnaire (EMQ.Material and Methods: A sample of community-dwelling elderly individuals was recruited (766 controls and 78 MCI. The Everyday Memory Questionnaire (EMQ was administered to measure self-perception of cognitive complaints. All participants also underwent a comprehensive clinical and neuropsychological battery. Combined exploratory factor analysis and item response theory were performed to identify the underlying structure of the EMQ. Furthermore, logistic regression analyses were conducted to study whether single cognitive complaints were able to predict MCI.Results: A suitable five-factor solution was found. Each factor focused on a different cognitive domain. Interestingly, just three of them, namely forgetfulness of immediate information, executive functions and prospective memory proved to be effective in distinguishing between cognitively healthy individuals and MCI. Based on these results we propose a shortened EMQ version comprising 10 items (EMQ-10.Discussion: Not all cognitive complaints have the same clinical relevance. Only subjective complaints on specific cognitive domains are able to discriminate MCI. We encourage clinicians to the EMQ-10 as a useful tool to quantify and monitor the progression of individuals who report cognitive complaints.

n-3PUFA consumption has been widely accepted as a nutritional strategy for the secondary prevention of cardiovascular events in patients at high risk of cardiovascular disease (CVD), but little is known about the dose-response relationship between dietary n-3PUFA and serum biomarkers associated with cardiovascular health in the general population. The present study involved a 12-week double-blind, randomized controlled trial to explore the effects of fish oil with different doses (0.31, 0.62 and 1.24 g d-1 of EPA and DHA) on serum fatty acids and cardio-metabolic biomarkers including adiponectin, inflammatory markers, lipid profiles and fasting glucose in healthy middle-aged and elderly Chinese people. 240 volunteers met our inclusion criteria. A total of 39 subjects dropped out and 201 finally completed the intervention. No significant differences in baseline characteristics and daily intakes of dietary nutrients were detected among all groups. After a 12-week intervention, fish oil dose-dependently enhanced serum EPA, DHA, n-3PUFA and adiponectin (except for 0.31 g d-1), but decreased serum n-6/n-3PUFA, TG and fasting glucose. Changes in the above indicators from the baseline to week 12 in fish oil groups significantly differed from those in the control. Meanwhile, all the doses of EPA and DHA led to decreases in serum CRP; only 1.24 g d-1 led to an increase in HDL-C with a concurrent decrease in TC/HDL-C even though these changes were not significantly different among all groups. All the findings suggested that fish oil dose-dependently regulated serum PUFA and cardio-metabolic biomarkers including adiponectin, CRP, lipid profiles and fasting glucose in healthy middle-aged and elderly Chinese people who consumed insufficient dietary n-3PUFA, and the most desirable changes were observed for 1.24 g d-1.

Renal function of erderly persons was evaluated by the radionuclide renal function test based on the renal uptake rate and the renal volume determined by Tc-99m-DMSA transectional tomographic images using single photon emission computed tomography (SPECT). Forty-three erderly cases (13 healthy persons and 30 patients with various types of renal disorders) aged between 60 and 87 on an average of 70 were studied and compared with results obtained from 20 healthy adults (18 - 45 years old). Renal volume was calculated from the summation of voxels in the region districted by equi-count threshold level (percentage to maximum count) on each section of the SPECT image. Attenuation correction was made by GE-STAR protocol utilizing Sorrenson's precorrection method. The renal uptake rate was expressed as a percentage of the total radioactivity detected within the renal volume, against an amount of dose injected. In the 26 kidneys of 13 healthy elderly persons, Tc-99m-DMSA renal uptake was 23 ± 5 %, which was significantly lower (p < 0.01) than that of healthy adults being 27 ± 2 %. A correlation coefficient between renal volume and uptake of 79 kidneys of 43 elderly persons was 0.5081 (p < 0.01). Creatinine clearance (Ccr) was better correlated with the total renal uptake (r = 0.6471, p < 0.01) than with the total renal volume (r = 0.3592, p < 0.01). This method is considered to be useful for clinical purpose as a test of renal function for elderly persons since it requires neither blood nor urine samples. (author)

Demographic changes will lead to a growing demand for healthy, motivated healthcare workers (HCW) in the years ahead. Along with well-targeted prevention, knowledge of occupational health and safety and infection precaution is essential for a healthy working life. In this context back-friendly working methods and protection from infectious diseases are necessary in elderly care. In 2012, a survey was conducted in nine residential and two semi-residential nursing homes, as well as in one home care service in the Schwerin area of northeast Germany. Four hundred and seventy three HCWs were asked to fill in a questionnaire on what they knew about aspects of occupational health and safety such as vaccinations and preventative measures administered by occupational physicians, hygiene, back-friendly working methods and infection prevention. The statistical evaluation was descriptive, with a comparison between job title. Differences were examined with chi square or Fisher's exact test. The response rate was 28 % (n = 132). The largest group of respondents (36 %) were qualified geriatric HCWs. More than 74 % of employees felt well informed about opportunities for precautionary checks and vaccination by occupational physician, and 93 % utilized these opportunities. When it came to assigning modes of transmission to specific infectious diseases, only 23 % of participants were well informed, and one in three (31 %) care assistants was inadequately informed. Fewer than half of participants could correctly name the indications for hand disinfection. Only 66 % of the HCWs said they were aware of training offers for the management of multidrug-resistant organisms in their institution. They did know about possible aids to back-friendly working, although gaps in knowledge were apparent. Only 59 % of respondents knew that care utensils should preferably be stored at working height so as to reduce awkward body postures. Employees in elderly care are well informed about the

Ubiquitous system of regulatory, calcium-dependent, cytoplasmic proteases - calpains - and their endogenous inhibitor - calpastatin - is implicated in the proteolytic regulation of activation, proliferation, and apoptosis of many cell types. However, it has not been thoroughly studied in resting and activated human lymphocytes yet, especially in relation to the subjects' ageing process. The CALPACENT project is an international (Polish-Italian) project aiming at verifying the hypothesis of the role of calpains in the function of peripheral blood immune cells of Polish (Pomeranian) and Italian (Sicilian) centenarians, apparently relatively preserved in comparison to the general elderly population. In this preliminary report we aimed at establishing and comparing the baseline levels of expression of μ- and m-calpain and calpastatin in various, phenotypically defined, populations of human peripheral blood lymphocytes for healthy elderly Sicilians and Poles, as compared to these values observed in young cohort. We have found significant differences in the expression of both μ- and m-calpain as well as calpastatin between various populations of peripheral blood lymphocytes (CD4+, CD8+ and CD19+), both between the age groups compared and within them. Interestingly, significantly higher amounts of μ- and m-calpains but not of calpastatin could be demonstrated in the CD4+CD28- and CD8+CD28- lymphocytes of old subjects (but not in the cells of young individuals), as compared to their CD28+ counterparts. Finally, decreased expression of both calpains in the elderly T cells is not related to the accumulation of effector/memory (CD45RO+) cells in the latter, as the expression of both calpains does not differ significantly between the naïve and memory T cells, while is significantly lower for elderly lymphocytes if both populations are taken separately. Observed differences in the amounts of CCS member proteins between various populations of lymphocytes of young and elderly

This study aimed to uncover the fundamental nature of living alone in female elderly. The phenomenological research approach developed by van Manen was adopted. The theme was 'taking a firm stand alone on the edges of life'. The composition elements of living alone experienced by elderly women were as follows: 1) Corporeality: participants perceived their bodies by their health status. Unhealthy participants were suffering with diseases and dependant on other persons, while healthy participants were free from family responsibility and kept on moving. 2) Spatiality: participants felt both freedom and loneliness while they stayed home. 3) Relationality: participants felt pity and yearning for their bereaved husband and sometimes talked to his picture. According to their children's filial piety, participants were pleased or displeased. However, they incessantly devoted themselves to their children. 4) Temporality: participants considered the rest of their life as extra-time which was proceeding to death, and tried to keep themselves busy before they died. A nurse should understand the multifarious aspects of elderly women's life, and then intervene to consolidate their strengths for self-supporting the final years of life.

Demographic changes in the 21st century, increased population of the elderly and high prevalence of related diseases call for new healthcare strategies that can change the behavior and lifestyle of elderly individuals. Innovative information and communication technology, such as mobile health (mHealth), can play a significant role. The present study was conducted aiming to assess the effectiveness of mHealth in improving health behaviors among an elderly population. This paper presents a systematic review involving a search of PubMed, Web of Science (ISI), Scopus, Science Direct and Embase databases from [2012-2016]. Our search resulted after initial evaluations 12 articles. Inclusion criteria mostly revolved around interventional studies, other studies were excluded because of their methodology, non-elderly target groups and irrelevant to the subject. Findings showed that mHealth can improve care, self-management, self-efficacy, behavior promotion (quality of sleep, diet, physical activity mental health) and medication adherence. The mHealth technology has proven effective for disease prevention, lifestyle changes, management of cardiovascular disease and diabetes, and is a suitable tool for elderly people. In conclusion, it seems that mHealth can facilitate behavioral changes; although, further research is necessary in this regard.

Full Text Available Introduction: Physical activity and a healthy diet are significant predictors of healthy ageing—they help the elderly maintain their physical and mental health, and prevent chronic diseases. Methods: The data for the empirical quantitative survey were collected on the sample of 218 elderly community-dwelling participants (aged 65 years or more, using a structured questionnaire for self-reporting. Data analyses were proceed with the bivariate statistics, and multivariate hierarchical cluster analysis. Results: Most respondents reported good dietary habits (83.1% and a satisfactory physical activity level (60.5%. On average, the elderly eat 3-4 meals per day (59.8% and engage in physical activity at least three times a week (58.6%, with interventions lasting 15 minutes or more (84.4 % and non-organized activity prevailing (96.2%. Ward’s method yielded three clusters with homogenous dietary and physical activity patterns: ‘Health Conscious’ (30.8%, ‘At Risk’ (42.7% and ‘Special Requirements’ (26.5%. Significant differences were identified between clusters and educational level (p = 0.001. Discussion and conclusions: In the future, special attention should be placed on the elderly group with a lower educational level and special dietary and physical activity requirements. Additional studies on representative samples are required for a comprehensive investigation into the lifestyle behaviours of elderly individuals.

2012-11-01

Salivary chromogranin A (CgA) levels and salivary flow rates were measured to evaluate the stress relief effect of laughter on the young and the elderly. Thirty healthy volunteers (15 aged 20-25 years; 15 aged 62-83 years) performed a serial arithmetic task for 15 min and then watched a comedy video for 30 min. On a different day, as a control, they watched a non-humorous video after performing a task similar to the first one. Saliva samples were collected immediately before and after the arithmetic task, 30 min after completing the task (immediately after watching the film), and 30 min after watching the film (60 min after completing mental task). Salivary CgA levels were determined by enzyme-linked immunosorbent assay. In the elderly group, salivary flow rates, which had declined by the end of the arithmetic task, were statistically significantly higher after watching the comedy video. In the young group, salivary CgA levels, which had increased by the end of the task, had statistically significantly declined after watching the comedy video. No such post-task changes were apparent in control results; in the young group, there was a statistically significant interprotocol difference in salivary CgA levels. These findings suggest that laughter may relieve stress, particularly in the young people.

The Acute Risks of Exercise in Apparently Healthy Adults and Relevance for Prevention of Cardiovascular Events.

Goodman, Jack M; Burr, Jamie F; Banks, Laura; Thomas, Scott G

Increased physical activity (PA) is associated with improved quality of life and reductions in cardiovascular (CV) morbidity and all-cause mortality in the general population in a dose-response manner. However, PA acutely increases the risk of adverse CV event or sudden cardiac death (SCD) above levels expected at rest. We review the likelihood of adverse CV events related to exercise in apparently healthy adults and strategies for prevention, and contextualize our understanding of the long-term risk reduction conferred from PA. A systematic review of the literature was performed using electronic databases; additional hand-picked relevant articles from reference lists and additional sources were included after the search. The incidence of adverse CV events in adults is extremely low during and immediately after PA of varying types and intensities and is significantly lower in those with long-standing PA experience. The risk of SCD and nonfatal events during and immediately after PA remains extremely low (well below 0.01 per 10,000 participant hours); increasing age and PA intensity are associated with greater risk. In most cases of exercise-related SCD, occult CV disease is present and SCD is typically the first clinical event. Exercise acutely increases the risk of adverse CV events, with greater risk associated with vigorous intensity. The risks of an adverse CV event during and immediately after exercise are outweighed by the health benefits of vigorous exercise performed regularly. A key challenge remains the identification of occult structural heart disease and inheritable conditions that increase the chances of lethal arrhythmias during exercise.

The aim of the study was to examine the correlation between KCNJ11 gene polymorphism and metabolic syndrome in elderly patients. From January 2014 to January 2015, 54 elderly patients with metabolic syndrome were enrolled in this study as the observation group. During the same period, 46 healthy elderly individuals were enrolled in this study as the control group. KCNJ11 gene polymorphism (rs28502) was analyzed using polymerase chain reaction-restriction fragment length polymorphism. The expression levels of mRNA in different genotypes were detected using FQ-PCR. ELISA was used to evaluate the KCNJ11 protein expression in different genotypes. KCNJ11 gene polymorphism and metabolic syndrome was studied by measuring the blood pressure levels in patients with different genotypes. Three genotypes of KCNJ11 gene in rs28502 were CC, CT and TT. The CC, CT and TT genotype frequencies in healthy population were 8.5, 9.2 and 82.2%, respectively, while the genotype frequencies in patients with metabolic syndrome were 42.4, 49.8 and 7.8%, respectively. There were significant differences between groups (P≤0.05). However, the genotype frequencies of C/T in healthy individuals and metabolic syndrome patients were 35.3 and 38.3%, respectively. There were no significant differences between groups (P>0.05). FQ-PCR results showed that the KCNJ11 mRNA expression levels in the control and observation groups had no significant differences (P>0.05). However, the results obtained from ELISA analysis revealed that KCNJ11 protein expression level in the observation group was significantly higher than that in the control group (Pmetabolic syndrome in the elderly. Elderly patients with the CC and TT genotypes are more likely to develop metabolic syndrome.

Full Text Available Abstract Background The aim of our study was to compare the presence of the intI1 gene and its associations with the antibiotic resistance of commensal Escherichia coli strains in children with/without previous antibiotic treatments and elderly hospitalized/healthy individuals. Methods One-hundred-and-fifteen intestinal E. coli strains were analyzed: 30 strains from 10 antibiotic-naive infants; 27 from 9 antibiotic-treated outpatient infants; 30 from 9 healthy elderly volunteers; and 28 from 9 hospitalized elderly patients. The MIC values of ampicillin, cefuroxime, cefotaxime, gentamicin, ciprofloxacin, and sulfamethoxazole were measured by E-test and IntI1 was detected by PCR. Results Out of the 115 strains, 56 (49% carried class 1 integron genes. Comparing persons without medical interventions, we found in antibiotic-naive children a significantly higher frequency of integron-bearing strains and MIC values than in healthy elderly persons (53% versus 17%; p Conclusion The prevalence of integrons in commensal E. coli strains in persons without previous medical intervention depended on age. The resistance of integron-carrying and non-carrying strains is more dependent on influencing factors (hospitalization and antibiotic administration in particular groups than merely the presence or absence of integrons.

In healthy humans, lymphocyte populations are maintained at a relatively constant size throughout life, reflecting a balance between lymphocyte production and loss. Given the profound immunological changes that occur during healthy aging, including a significant decline in T-cell production by the thymus, lymphocyte maintenance in the elderly is generally thought to require homeostatic alterations in lymphocyte dynamics. Surprisingly, using in vivo (2) H2 O labeling, we find similar dynamics of most lymphocyte subsets between young adult and elderly healthy individuals. As the contribution of thymic output to T-cell production is only minor from young adulthood onward, compensatory increases in peripheral T-cell division rates are not required to maintain the T-cell pool, despite a tenfold decline in thymic output. These fundamental insights will aid the interpretation of further research into aging and clinical conditions related to disturbed lymphocyte dynamics. © 2015 The Authors.

Provision of a valid and reliable safety climate dimension brings enormous benefits to the elderly home sector. The aim of the present study was to make use of the safety climate instrument developed by OSHC to measure the safety perceptions of employees in elderly homes such that the factor structure of the safety climate dimensions of elderly homes could be explored. In 2010, surveys by mustering on site method were administered in 27 elderly homes that had participated in the "Hong Kong Safe and Healthy Residential Care Home Accreditation Scheme" organized by the Occupational Safety and Health Council. Six hundred and fifty-one surveys were returned with a response rate of 54.3%. To examine the factor structure of safety climate dimensions in our study, an exploratory factor analysis (EFA) using principal components analysis method was conducted to identify the underlying factors. The results of the modified seven-factor's safety climate structure extracted from 35 items better reflected the safety climate dimensions of elderly homes. The Cronbach alpha range for this study (0.655 to 0.851) indicated good internal consistency among the seven-factor structure. Responses from managerial level, supervisory and professional level, and front-line staff were analyzed to come up with the suggestion on effective ways of improving the safety culture of elderly homes. The overall results showed that managers generally gave positive responses in the factors evaluated, such as "management commitment and concern to safety," "perception of work risks and some contributory influences," "safety communication and awareness," and "safe working attitude and participation." Supervisors / professionals, and frontline level staff on the other hand, have less positive responses. The result of the lowest score in the factors - "perception of safety rules and procedures" underlined the importance of the relevance and practicability of safety rules and procedures. The modified OSHC

Focusing on relevant information while suppressing the irrelevant one are critical abilities for different cognitive processes. However, their functioning has been scarcely investigated in the working memory (WM) domain, in both healthy and pathological conditions. The present research aimed to study these abilities in aging and Parkinson's disease (PD), testing three groups of healthy participants (young, older and elderly) and one of PD patients, employing a new experimental paradigm. Results showed that the transient storing of irrelevant information in WM causes substantial interference effects, which were remarkable in elderly individuals on both response latency and accuracy. Interestingly, PD patients responded faster and were equally accurate compared to a matched control group. Taken together, findings confirm the existence of similar mechanisms for orienting attention inwards to WM contents or outwards to perceptual stimuli, and suggest the suitability of our task to assess WM functioning in both healthy aging and PD.

There is increasing evidence that physical activity (PA) positively affects cognitive function (CF). Existing research has focussed on this association in children and the elderly, with less research available in young to middle-aged adults who constitute a substantial proportion of the population. A systematic review investigating the relationship between habitual PA (≥12 months) and CF in young to middle-aged adults (18-50 years). A search was conducted using AMED, CINAHL, MEDLINE, PsychINFO, AUSPORT MED and SPORTDiscus databases. Eligible studies had to report descriptive statistics for CF and PA levels in healthy participants 18-50 years. Effect sizes (ES) (Hedges g) were calculated where possible. The initial search netted 26,988 potentially relevant manuscripts, with four more identified through hand searching. Fourteen were included for review. A range of validated platforms assessed CF across three domains: executive function (12 studies), memory (four studies) and processing speed (seven studies). Habitual PA was assessed via questionnaire/self-report methods (n=13, 8 validated) or accelerometers (n=1). In studies of executive function, five found a significant ES in favour of higher PA, ranging from small to large. Although three of four studies in the memory domain reported a significant benefit of higher PA, there was only one significant ES, which favoured low PA. Only one study examining processing speed had a significant ES, favouring higher PA. A limited body of evidence supports a positive effect of PA on CF in young to middle-aged adults. Further research into this relationship at this age stage is warranted. Copyright © 2015 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

Aim: To investigate the effects of age and gender on apparent diffusion coefficient (ADC) measurements of bilateral kidneys at 3 T MRI, and compare the ADC values of left and right kidneys. Materials and methods: In all, 137 healthy participants (mean age 42.8 ± 14.7 years; age range 16–75 years) comprising 68 male and 69 female participants were enrolled. Three Tesla echo-planar diffusion-weighted imaging (DWI) of bilateral kidneys was performed and ADC values were measured in the cortex, medulla, and whole parenchyma. Pearson correlation analysis and linear regression were performed to determine the associations between the ADC values in each region and age. Effects of age and gender on ADC values were analysed using two-factor analysis of variance (ANOVA). The paired-samples t-test was established to compare the ADC values between left and right kidneys. Results: ADC values were significantly higher in the young group (≤50 years) than in the old group (>50 years), and correlated inversely with the age in all regions. Male participants had higher ADC values than female participants in all regions except left medulla. Two-factor ANOVA of age × gender showed no significant interactions between the variables age and gender were found. No significant differences in ADC values between left and right kidneys were observed. Conclusion: Renal ADC values are age- and gender-dependent, and show no significant difference between left and right kidneys. Age- and gender-related effects should be taken into consideration in future renal DWI studies when using normal ADC values from health controls. - Highlights: • Renal apparent diffusion coefficient (ADC) values decrease with ageing. • Men tend to have higher renal ADC values than women. • Bilateral kidneys seem to have no significantly different ADC values

Natália GASPARETO

Full Text Available ABSTRACT Objective We evaluated factors associated with protein consumption by the elderly. Methods We performed a cross-sectional study in a sample of 295 elderly consumers of health facilities in São Caetano do Sul, São Paulo, Brazil. Protein consumption data (g and g/kg were obtained through 24-hour dietary recalls, which was reapplied in a 30% sub-sample to estimate habitual consumption, with an interval of two weeks. The association between protein consumption and sociodemographic, economic, health, and dietary variables was tested using multiple linear regression. Results There was a positive association between protein consumption (g and g/kg and better Brazilian Healthy Eating Index-Revised, between protein consumption (g and male sex, and a negative association between protein consumption (g/kg and greater calf circumference. Higher average protein consumption (g or g/kg was observed among married elderly, individuals with higher income and schooling, who were economically active, eutrophic, without dyslipidemia and symptoms of dysphagia, who consumed three main meals and an intermediate snack. Conclusion The results showed that protein consumption was associated with diet quality, sex, and calf circumference. The identification of elderly groups prone to protein inadequacy may direct individual and collective interventions to prevent muscle mass reduction and its implications, such as sarcopenia and other adverse outcomes.

Palliative care and elderly health in Brazil

2011-09-01

Full Text Available In recent years elderly population is increasing substantially, about 650,000 per year, as well as the concept of unifamílies, ie, families consisting of a single person. In this paper, is proposed a reflection about health of elderly in Brazil, and the conditions of a chronic disease and its acute state - terminal. In the actual society, capitalist and capitalized, the individual is valued by his production, losing his value when acquires a disabling illnesses. There is a growing need for work, and each time there is less time and resources to manage the permanence of an elderly patient at home, or pay for a caregiver. This situation leads families to resort to hospitalization, which in turn makes the hospitals overcrowded with patients in this state, affecting both emergency care as the treatment of chronic patients. This fact occurs due to lack of hospital infrastructure, as well by the lack of units of the healthy system capable of providing palliative care. The questioning about the elderly who need palliative care, and reflection about the type of care dispended for this kind of patient, should be the focal point of professional's reflections, capable to lead him to a new way of thinking and, consequently, to inspire him to act in a new way.

We conducted a clinical cross-sectional study to examine the relationship between jaw-opening force and the cross-sectional area of the suprahyoid muscles and whole skeletal muscle mass. Subjects were healthy 39 males and 51 females without dysphagia and sarcopenia, aged 65 years and older. Jaw-opening force was measured three times using a jaw-opening sthenometer; the maximum of these three was taken as the measurement value. The cross-sectional area of the geniohyoid and anterior belly of the digastric muscles were evaluated using ultrasonography. The skeletal muscle mass index, gait speed and grip strength were evaluated according to the diagnostic criteria of the Asian Working Group for Sarcopenia. For each sex, a multiple regression analysis determined the factors that affect jaw-opening force. Jaw-opening force was associated with the cross-sectional area of the geniohyoid muscle in males (regression coefficient [β] = 0.441, 95% confidence interval [CI] = 14.28-56.09) and females (β = 0.28, 95% CI = 3.10-54.57). Furthermore, in females only, jaw-opening force was associated with the skeletal muscle mass index (β = 0.40, 95% CI = 3.67-17.81). In contrast, jaw-opening force was not associated with the cross-sectional area of the anterior belly of the digastric muscle in either sex. In healthy elderly males and females, jaw-opening force was positively associated with the cross-sectional area of the geniohyoid muscle. However, the jaw-opening force was positively associated with the skeletal muscle mass index only in females. © 2017 John Wiley & Sons Ltd.

Toosizadeh, Nima; Mohler, Jane

2018-01-01

In our study we examined postural performance of young healthy persons (HY), elderly healthy persons (HE), and elderly persons at high risk of falling (FR). Anterio-posterior (AP) and medio-lateral (ML) ankle and hip angular deviations, as well as linear displacements of the center of mass (COM) were assessed in persons standing with eyes either open or closed, while none, and 40 and 30 Hz vibrations were applied bilaterally to the ankle muscle gastrocnemius. During quiet standing with eyes open, balance parameters in FR group differed from those in healthy groups. ML ankle and hip angular deviations, as well as COM linear displacements were noticeably larger in FR group. During quiet standing with eyes closed, all balance parameters in participants of all groups had a clear trend to increase. During standing with eyes open, 40 Hz vibration increased all but one balance parameter within HY group, ankle angular deviations in HE group, but none in FR group. In response to 30 Hz vibration, only ankle angular deviations and COM linear displacements increased in HY group. There were no changes in both elderly groups. During standing with eyes closed, 40 and 30 Hz vibrations did not produce consistent changes in balance parameters in HY and HE groups. In FR persons, 40 Hz vibration did not change balance parameters. However, in FR groups, 30 Hz vibration decreased ankle and hip angular deviations, and COM linear displacements. The major result of the study is a finding that low intensity vibration of ankle muscles makes balance better in elderly persons at high risk of falling. This result is clinically relevant because it suggests that applying mild vibration to ankle muscles while standing and walking might benefit elderly persons, improving their postural performance and reducing a risk of unexpected falls.

Balance can be quantified by clinical tests and through instrumental studies. The objective of this paper is to determine the correlation between static posturography and 4 clinical tests of balance in elderly people with vestibular disorders and to identify its capability to discriminate the groups studied. 60 patients with vestibular disorders and 60 healthy subjects performed 4 clinical tests (one leg standing with opened eyes, Timed Up and Go, Tinetti and Berg tests) and a static posturography analysis (NedSVE/IBV system) under 4 conditions: Romberg Test, Eyes Open (REO), Romberg Test, Eyes Closed (REC), Romberg Test on Foam with Eyes Open (RFEO), and Romberg Test on Foam with Eyes Closed (RFEC). RFEO correlated best with the clinical tests and RFEC was the worst. RFEO distinguished between healthy individuals and decompensated patients. RFEO gave the best information about postural balance in the elderly. RFEC was not useful. Static posturography can be useful to distinguish vestibular compensation status.

Apolipoprotein E (ApoE) ε4 genotype is a strong risk factor for developing Alzheimer's disease (AD). Conversely, the presence of the ε2 allele has been shown to mitigate cognitive decline. Tensor-based morphometry (TBM), a novel computational approach for visualizing longitudinal progression of brain atrophy, was used to determine whether cognitively intact elderly participants with the ε4 allele demonstrate greater volume reduction than those with the ε2 allele. Healthy "younger elderly" volunteers, aged 55-75, were recruited from the community and hospital staff. They were evaluated with a baseline and follow-up MRI scan (mean scan interval = 4.72 years, s.d. = 0.55) and completed ApoE genotyping. Twenty-seven participants were included in the study of which 16 had the ε4 allele (all heterozygous ε3ε4 genotype) and 11 had the ε2ε3 genotype. The two groups did not differ significantly on any demographic characteristics and all subjects were cognitively "normal" at both baseline and follow-up time points. TBM was used to create 3D maps of local brain tissue atrophy rates for individual participants; these spatially detailed 3D maps were compared between the two ApoE groups. Regional analyses were performed and the ε4 group demonstrated significantly greater annual atrophy rates in the temporal lobes (p = 0.048) and hippocampus (p = 0.016); greater volume loss was observed in the right hippocampus than the left. TBM appears to be useful in tracking longitudinal progression of brain atrophy in cognitively asymptomatic adults. Possession of the ε4 allele is associated with greater temporal and hippocampal volume reduction well before the onset of cognitive deficits.

Elderly people at risk of developing cognitive decline; e.g., following surgery, may benefit from structured, challenging, and repetitive cognitive video training. This study assessed usability and acute effects of a newly developed bedside console (COPHYCON). Fifteen healthy elderly individuals performed a one-time 80-min intervention, including cognitive video games aimed at improving awareness and selective attention. Perceived usefulness and perceived ease of use (Technology Acceptance Model) were assessed together with measures of the achieved game level, reaction times, (in-) correct responses during ALERT and SELECT game play. Further, prefrontal cortical involvement of the regional cerebral hemoglobin saturation (rS02%) assessed with functional near infrared spectroscopy (fNIRS) ( n = 5) and EEG power ( n = 10) was analyzed. All participants completed the study without any adverse events. Perceived usefulness and perceived ease of use (TAM scores range 1-7) of the system varied between 3.9 and 6.3. The game levels reached for awareness varied between 9 and 11 (initial score 8-10), for reaction speed between 439 and 469 ms, and for correct responses between 74.1 and 78.8%. The highest level for the selective attention games was 2 (initial score 1), where reaction speed varied between 439 and 469 ms, correct responses between 96.2 and 98.5%, respectively. The decrease of rS02% in the right prefrontal cortex during gameplay was significantly ( p games ( p games. EEG recordings of theta power significantly decreased in the averaged ~0.25-0.75 time interval for the left prefrontal cortex sensor across the cognitive game levels between the ALERT 1 and SELECT 1, as well as between SELECT 1 and 2 games. Participants rated the usability of the COPHYCON training positively. Further results indicate that video gaming may be an effective measure to affect prefrontal cortical functioning in elderly. The results warrant a clinical explorative study investigating the

Full Text Available BackgroundDepressed populations demonstrate a greater tendency to have negative interpretations on ambiguous situations. Cognitive theories concerning depression proposed that such a negative bias plays an important role in developing and maintaining depression. There is now fairly consistent evidence arising from different stimuli and assessment methods that depression is featured by such a bias. The current study aimed to explore the neural signatures associated with the interpretation bias in the elderly with depressive symptoms confronted with different facial expressions using event-related brain potentials (ERPs.MethodsParticipants were 14 community-dwelling older adults with depressive symptoms assessed by the Center for Epidemiologic Studies Depression scale scores. We collected event-related potentials of their brain compared to that of 14 healthy aged-matched adults. The late positive potential (LPP was used to examine cognitive-affective processes associated with judgment of emotional facial expressions between the two groups.ResultsOld adults with depressive symptoms have much smaller amplitude than healthy older adults irrespective of the prime types. When processing the targets, the two groups showed different patterns regarding the LPP. The healthy control group revealed no differences between ambiguous and happy primes, irrespective of whether the targets were sad or happy facial expressions. However, significant differences were found between happy and sad and between ambiguous and sad primes. Such a pattern indicates a positive bias in healthy elderly adults. Regarding the elderly with depressive symptoms, there were no significant differences between ambiguous versus happy, ambiguous versus sad primes, and happy versus sad primes. Concerning reaction times, there was no group difference. Thus, the findings provide some support for cognitive theories of depression.ConclusionThe current study shows that there is an association

Full Text Available There is growing recognition that the complications associated with type-2 diabetes may translate into functional impairments in older people.This cross sectional study was conducted between January and June 2008 to determine the influence of diabetes on physical functions in an elderly (³55 years population. Fifty-five elderly diabetics attending the out-patient department of a diabetic centre were selected by convenient sampling and compared with fifty-five non-diabetic elderly persons of the near-by community. Their physical functions were assessed by Barthel Index, SF-36 Health Survey and Modified Physical Performance test. Diabetic elderly persons, on average, obtained lower scores in all these three tests. After removing the effect of socio-demographic variables, influence of diabetes on level of independence measured by Barthel Index did not persist. However, the difference in SF-36 health survey and Modified Physical Performance test scores between diabetics and non-diabetics remained significant after controlling for socio-demographic variables. The current study showed influence of diabetes on physical functions in the elderly. People should be motivated and guided properly to practice a healthy lifestyle in order to prevent and control diabetes and thus avoid complications of diabetes mellitus and disabilities in later life.

Age-related changes of body composition affect health status. This study aims at clarifying body composition changes in healthy elderly subjects, and evaluating the impact of physical activity on these changes. In 1999, 213 subjects ≥ 65 years recruited through advertisements underwent assessment of health state, energy expenditure by physical activity, body composition by bioimpedance analysis and body cell mass by total body potassium. In 2008, 112 of them repeated these assessments with additional determination of Barthel index, Mini Mental State Examination and Geriatric Depression Score. Lean tissues decreased in both genders (p men: -3.7 ± 5.4 vs. 0.4 ± 5.4 kg, women: -3.6 ± 5.5 vs. 0.3 ± 5.2 kg, both p men: -3.6 ± 3.3 vs. -0.4 ± 2.7 kg, women: -1.8 ± 2.3 vs. -0.1 ± 2.5 kg, both p physical activity limited lean tissue loss in men but not in women. Loss of lean tissues occurs exponentially with aging. Further research should confirm these changes in subjects over 80 years. Increasing physical activity limits fat-free mass loss in men but not women. Copyright © 2011 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.

OBJECTIVES: To determine the effects of congestive heart failure on a person's ability to walk at a steady pace while ambulating at a self-determined rate. SETTING: Beth Israel Hospital, Boston, a primary and tertiary teaching hospital, and a social activity center for elderly adults living in the community. PARTICIPANTS: Eleven elderly subjects (aged 70-93 years) with well compensated congestive heart failure (NY Heart Association class I or II), seven elderly subjects (aged 70-79 years) without congestive heart failure, and 10 healthy young adult subjects (aged 20-30 years). MEASUREMENTS: Subjects walked for 8 minutes on level ground at their own selected walking rate. Footswitches were used to measure the time between steps. Step rate (steps/minute) and step rate variability were calculated for the entire walking period, for 30 seconds during the first minute of the walk, for 30 seconds during the last minute of the walk, and for the 30-second period when each subject's step rate variability was minimal. Group means and 5% and 95% confidence intervals were computed. MAIN RESULTS: All measures of walking variability were significantly increased in the elderly subjects with congestive heart failure, intermediate in the elderly controls, and lowest in the young subjects. There was no overlap between the three groups using the minimal 30-second variability (elderly CHF vs elderly controls: P young: P < 0.001), and no overlap between elderly subjects with and without congestive heart failure when using the overall variability. For all four measures, there was no overlap in any of the confidence intervals, and all group means were significantly different (P < 0.05).

Full Text Available Objectives: The purpose of this study was to design and determine the psychometric properties of a checklist for assessing domestic elder neglect. Methods & Materials: This study was conducted in four phases. In the first phase, the meaning of domestic elder neglect explored using the qualitative method of phenomenology. In the second phase, a checklist was created, based on the results obtained in the first phase, in conjunction with the inductions from the expert panel. In the third and fourth phases, the psychometric properties including face validity, content validity, construct validity, convergent validity, internal consistency, and Inter- rater reliability were measured. 110 elderly people participated in the this study. Results: The initial 26 item checklist designed using the results of first and second phases of study, reduced to 11 items and 2 factors including the health and care needs neglect, and neglect in providing healthy environment in the process of determining the face and content validity. Acceptable convergent validity was identified in the elder neglect checklist and care neglect scale of the domestic elder abuse questionnaire (r=0.862. The results of known groups' comparisons showed that this checklist could successfully discriminate between subgroups of elderly people in the index of re-hospitalization. The internal consistency (Kuder-Richardson Formula 20 was 0.824. Inter- rater reliability of the checklist was 0.850. Conclusion: The elder neglect checklist with 11 items appears to be a promising tool, providing reliable and valid data helping to detect neglect among elders in different settings such as clinical settings, homes and research environments by health care providers and researchers.

Summary Obesity is associated with the metabolic syndrome. The aims were, first, to study the postprandial triglyceride clearance in young, healthy obese subjects and, second, to investigate if fasting triglycerides can predict delayed postprandial triglyceride clearance. Eighteen apparently healthy, obese subjects with no clinical signs of metabolic disturbances participated. Controls were age‐ and sex‐matched, healthy, normal weight subjects. Subclinical markers of metabolic disturbances were assessed by measuring postprandial triglycerides in serum and in chylomicrons by oral fat tolerance test. Postprandial triglyceride clearance for 8 h was assessed indirectly as removal of the lipid from serum during the oral fat tolerance test. Insulin resistance was measured by the homeostasis model assessment of insulin resistance (HOMA‐IR). Twelve (66%) of the apparently healthy obese individuals had insulin resistance measured by HOMA‐IR. There was a delayed clearance of serum triglycerides and chylomicron triglycerides at 6 h when compared with the control group, while, at 8 h, the differences were only detected for the chylomicron triglyceride clearance. Triglyceride response was significantly greater in the obese subjects. Fasting triglycerides in upper normal level predicted a delayed postprandial triglyceride clearance and insulin resistance. In young, apparently healthy obese subjects early metabolic disturbances including insulin resistance and delayed postprandial triglyceride clearance can be detected. Fasting serum triglyceride in upper normal level predicted delayed postprandial triglyceride clearance and insulin resistance. PMID:26469529

Elderly are confronted with reduced physical capabilities and increased metabolic energy cost of walking. Exoskeletons that assist walking have the potential to restore walking capacity by reducing the metabolic cost of walking. However, it is unclear if current exoskeletons can reduce energy cost in elderly. Our goal was to study the effect of an exoskeleton that assists plantarflexion during push-off on the metabolic energy cost of walking in physically active and healthy elderly. Seven elderly (age 69.3±3.5y) walked on treadmill (1.11ms 2 ) with normal shoes and with the exoskeleton both powered (with assistance) and powered-off (without assistance). After 20min of habituation on a prior day and 5min on the test day, subjects were able to walk with the exoskeleton and assistance of the exoskeleton resulted in a reduction in metabolic cost of 12% versus walking with the exoskeleton powered-off. Walking with the exoskeleton was perceived less fatiguing for the muscles compared to normal walking. Assistance resulted in a statistically nonsignificant reduction in metabolic cost of 4% versus walking with normal shoes, likely due to the penalty of wearing the exoskeleton powered-off. Also, exoskeleton mechanical power was relatively low compared to previously identified optimal assistance magnitude in young adults. Future exoskeleton research should focus on further optimizing exoskeleton assistance for specific populations and on considerate integration of exoskeletons in rehabilitation or in daily life. As such, exoskeletons should allow people to walk longer or faster than without assistance and could result in an increase in physical activity and resulting health benefits.

We searched for the protective effect of a natural extract from stem bark of Mangifera indica L. extract (Vimang) on age-related oxidative stress. Healthy subjects were classified in two groups, elderly (>65 years) and young group (Vimang tablets, 300 mg each, before meals) for 60 days. Serum concentration of lipid peroxides, serum peroxidation potential, extracellular superoxide dismutase activity (EC-SOD), glutathione status (GSH, GSSG, GSSG/GSH ratio)) and total antioxidant status (TAS) were determined before (both experimental groups) and 15, 30, and 60 days after treatment (only elderly group). We confirmed the existence of an age-associated oxidative stress in human serum as documented by an age-related increase in serum lipoperoxides and GSSG and a decrease in serum antioxidant capacity and EC-SOD activity. Vimang tablet supplementation increased EC-SOD activity (p Vimang tablets prevent age-associated oxidative stress in elderly humans, which could retard the onset of age-associated disease, improving the quality of life for elderly persons.

Newly arrived elderly immigrants: a concept analysis of "aging out of place".

Science.gov (United States)

Sadarangani, Tina R; Jun, Jin

2015-03-01

Newcomer elderly immigrants, defined as adults older than the age of 65 who have arrived in the United States in the last 10 years, represent a growing sector of the American population. Newcomers who experience limited English proficiency, financial strain, and acculturative stress are at considerable risk of developing poor health outcomes. Nursing's focus on healthy aging and aging in place has largely ignored the experiences of these older adults, who are said to be "aging out of place." This concept analysis uses Rodgers's evolutionary method to define "aging out of place" and illustrates why existing theories of elderly migration do not necessarily apply to this population. The challenge for nurses is incorporating the family, with whom conflict may arise, into the care of these elders. Community-based strategies that enable social integration and create a greater division of labor in the care of newcomer elders are called for. © The Author(s) 2014.

To evaluate increased bone uptake of radionuclides at lumbar vertebra in elderly subjects, comparative study of bone scintigram with CT findings and autopsy finding of bone were performed. Incidence of abnormal increased bone uptake were 59 % in neoplastic disease group, while 50 % in benign disease group, respectively. Bone uptake of radionuclides to thoracic and lumbar vertebrae revealed marked high incidence even in both group. 13 out of 25 cases which revealed bone uptake at lumbar vertebrae in malignant disease group showed metastatic bone lesions and the rest of these cases did not show no apparent macroscopic metastatic bone lesions. In comparative study with CT findings of 18 cases most cases revealed osteosclerotic and osteoperotic changes of bone and fracture on CT imaging at the sites where bone uptake of radionuclides were observed. Thus, these evidence support that ageing process of bone must be considered as important factors to evaluate bone scintigram imaging in elderly subjects. (author)

Full Text Available INTRODUCTION : Exercise-induced ventricular arrhythmia (EIVA and autonomic imbalance are considered as early markers of heart disease in Chagas disease (ChD patients. The objective of the present study was to verify the differences in the occurrence of EIVA and autonomic maneuver indexes between healthy individuals and ChD patients with no apparent cardiac involvement. METHODS : A total of 75 ChD patients with no apparent cardiac involvement, aged 44.7 (8.5 years, and 38 healthy individuals, aged 44.0 (9.2 years, were evaluated using echocardiography, symptom-limited treadmill exercise testing and autonomic function tests. RESULTS : The occurrence of EIVA was higher in the chagasic group (48% than in the control group (23.7% during both the effort and the recovery phases. Frequent ventricular contractions occurred only in the patient group. Additionally, the respiratory sinus arrhythmia index was significantly lower in the chagasic individuals compared with the control group. CONCLUSIONS : ChD patients with no apparent cardiac involvement had a higher frequency of EIVA as well as more vagal dysfunction by respiratory sinus arrhythmia. These results suggest that even when asymptomatic, ChD patients possess important arrhythmogenic substrates and subclinical disease.

Age-specific incidence of hip fracture in the elderly: a healthy decline.

LENUS (Irish Health Repository)

Green, C

2012-02-01

Hip fractures in the elderly are an important source of morbidity and mortality. The predicted increase in the number of hip fractures due to the increasing elderly population has not been universally observed. The purpose of this study was to examine the incidence of hip fractures over a twenty year period to determine if this rise is occurring in our region. All hip fractures from the unit over 20 years were identified. Population data for those over 65 in the catchment area of our hospital was acquired. The rate of fractures occurring each year relative to the population was determined. The results were split into age groups. There was a strong correlation between the population rise and number of fractures (p = 0.77). But there was no significant difference in the rate of fracture over time (p = 0.41). However, the average age at which fracture occurred increased by two years. In addition we show the overall trend in the rate of fractures decreases in the younger age groups and increases in the older age groups. Therefore, the predicted rapid increase in rate is not occurring. This probably reflects the strengthening of the economy in Ireland from the 1930\\'s onwards, leading to a healthier population.

Full Text Available This study examined the relationships between the cognitive functions and mood of elders in an institution. Nine elders received the POMS (Profile of Mood Scale: Tense-Anxiety, Depression, Angry, Vigor, Fatigue, Confusion to measure their mood and the Stroop test and the reverse-Stroop test to measure their cognitive functions. The Stroop interference shows that elders' responses are influenced by word when they name the ink-color of an interfered color-word combination. The reverse-Stroop interference shows that they are interfered by color when they name the word of an incongruent color-word combination. POMS scores were under the cut-off points, and the total correct response score related with Vigor (r=0.62, p=0.04. The Stroop interference score was at the standard level, but the reverse-Stroop interference score was lower than that. The Stroop interference score related with Vigor (r=−0.65, p=0.03; the inverse-Stroop interference score related with Tense-Anxiety (r=−0.70, p=0.02 and Confusion (r=−0.61, p=0.04. These results show that 1 the mood of elders in the institution were at a healthy level and elders with high vigor responded correctly, 2 they could read word with high level, 3elders with high vigor treated color correctly without interference by word, and 4 elders with high tension and confusion treated with word without inference by color.

. The article illustrates how working consciously with the researcher's subjectivity makes it possible to understand apparently irrational patterns. The insights thus gained may be used to prevent withdrawals in care work as an argument for care workers' need for emotional supervision....... relations, independently of whether we are in the role of care providers or care receivers. Through collusion theory, the interpretation accepts both the anxiety which the helpless elderly people arouse in the care workers and their motivation for care work as two sides of a subjectively important theme...

PHARMACOTHERAPY IN ELDERLY NEUROPATHIC PAIN

2013-10-01

Full Text Available Normal 0 false false false IN X-NONE X-NONE MicrosoftInternetExplorer4 The incidence of pain increases with age. Neuropathic pain are common in elderly patients and pose challenges in both their diagnosis and treatment. The most common neuropathic pain in elderly are radiculopathy due to foraminal or spinal stenosis, diabetic neuropathy, and postherpetic neuralgia. Pain in the elderly is often unrecognized and undertreated. The main problem with pain in older adults relates to impaired quality of life secondary to pain which may be expressed by depression (including increased suicide risk, anxiety, sleep disruption, appetite disturbance, and weight loss, cognitive impairment, and limitations in the performance of daily activities. Pain management in elderly patients requires a different perspective from that of younger patients. Causes, comorbidities, and responses to both pain and its treatment differ between young healthy and older patients. Effective pain management in elderly patients should include both pharmacologic and nonpharmacologic strategies. Pharmacological approaches are the first line of pain management in older person for neuropathic pain. Pharmacologic strategies call for administration of nonopioid analgesics, opioid analgesics, and adjuvant medication. Polypharmacy, drug-drug and drug-disease interactions, age-associated changes in drug metabolism, and the high frequency of adverse drug reactions need to be carefully considered in using medications in this population /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso

2014-01-01

A healthy and active life is a key issue for elderly citizens, above all when psychological complications such as depression and anxiety disorders, late delusion or loneliness can be observed. Moreover, medical pathologies in elderly patients often have a multi-factorial etiology and many psychopathological dimensions and psychosocial risk factors are underestimated. From the perspective of clinical health psychology, psychogeriatrics could play an important role in promoting active ageing and a healthy lifestyle in elderly persons through tailored clinical approaches based on specific research and advanced professional training in this area. More research is needed in order to study which determinants affect the process of an active and functional ageing. Possible research ageing areas are: 1) evaluation of psychosocial risk-protective factors related to the individual's biography and personality. 2) Evaluation of enrichment programs and clinical protocols focused on the management of different topics such as health system areas, behavioral areas, social and physical environment areas, psychological factors and economic determinants. The goal of Psychogeriatrics endeavors to develop and evaluate interventions designed to stimulate improvement in friendship, self-esteem and subjective well-being, as well as to reduce loneliness among older citizens. 3) Evaluation of self-management programs in chronic disease conditions (such as obesity, diabetes, hypertension, poor nutrition, physical inactivity, alcohol abuse and tobacco smoking), that could enhance risk factors for health in elderly citizens. Typical key elements of self-management, such as decision making, problem solving, motivation, self-efficacy, resource utilization, and citizen's empowerment have to be studied.

Jonsson, P V; Lipsitz, L A; Kelley, M; Koestner, J

1990-07-01

Transient hypotension may be one of many factors contributing to the high prevalence of falls among elderly people. To determine the frequency and magnitude of hypotensive responses to common daily activities, and their potential relationship to falls in the elderly, we examined blood pressure (BP) and heart rate during a standardized series of activities in 38 institutionalized recurrent fallers (age, 87 +/- 6 years), 20 institutionalized nonfallers (age, 85 +/- 5 years), and 10 healthy young control subjects (age, 24 +/- 3 years). The coefficient of variation for systolic BP during all activities was higher in elderly subjects (fallers, 14% +/- 5%; nonfallers, 12% +/- 3%) than in young control subjects (8% +/- 1%). In contrast, the coefficient of variation for heart rate during all activities was higher in young subjects than in the elderly subjects. Elderly subjects had marked BP reduction following meals and nitroglycerin, which was significantly greater in fallers than in nonfallers, independent of the cause of the fall. Thus, institutionalized elderly have marked BP variability and hypotensive responses to meals and nitroglycerin. A decline in BP during common preload-reducing stresses may predispose some elderly people to falls.

Full Text Available Abstract Background Older heart failure (HF patients exhibit exercise intolerance during activities of daily living. We hypothesized that reduced lower extremity blood flow (LBF due to reduced forward cardiac output would contribute to submaximal exercise intolerance in older HF patients. Methods and Results Twelve HF patients both with preserved and reduced left ventricular ejection fraction (LVEF (aged 68 ± 10 years without large (aorta or medium sized (iliac or femoral artery vessel atherosclerosis, and 13 age and gender matched healthy volunteers underwent a sophisticated battery of assessments including a peak exercise oxygen consumption (peak VO2, b physical function, c cardiovascular magnetic resonance (CMR submaximal exercise measures of aortic and femoral arterial blood flow, and d determination of thigh muscle area. Peak VO2 was reduced in HF subjects (14 ± 3 ml/kg/min compared to healthy elderly subjects (20 ± 6 ml/kg/min (p = 0.01. Four-meter walk speed was 1.35 ± 0.24 m/sec in healthy elderly verses 0.98 ± 0.15 m/sec in HF subjects (p p ≤ 0.03. Conclusion During CMR submaximal bike exercise in the elderly with heart failure, mechanisms other than low cardiac output are responsible for reduced lower extremity blood flow.

Observational studies suggest healthy dietary patterns are associated with risk reduction and better control of various chronic diseases. However, few Brazilian studies have focused on evaluating the quality of the elderly diet and its relationship with diseases. This study aimed to estimate the association between diet quality and socioeconomic factors, health and nutrition of the elderly. This is a cross-sectional population-based study whose target population were non-institutionalized elderly residents in the city of Viçosa, Brazil. Anthropometric, socioeconomic, health conditions, lifestyle and food consumption variables were obtained from a semi-structured questionnaire. The quality of the diet was assessed by the revised Healthy Eating Index classified into tertiles, considering the first tertile as "Poor diet quality," the second as 'Intermediate diet quality' and the third as "Better diet quality." To identify factors independently associated with diet quality model, the works used multinomial logistic regression. In the results of the multivariate analysis, the factors independently associated with "better diet quality" included female gender, higher education, history of one to five medical visits in the past year, history of diabetes mellitus, dyslipidemia and the use of polypharmacy. Our results show that most seniors need to improve the quality of their diet and those of male gender with no or little education, and those who do not seek medical services constitute the group that needs attention concerning the measures to improve the quality of their diet.

The elderly as a market--challenges to evidence.

Ellwood, Roger P

To review the role of the oral care industry in the oral health of elders and opportunities for partnership with other key stakeholders. The elder population is growing at a faster rate than any other segment of the population. This is coupled with a greater probability of maintaining the dentition into later life and an increase in complex restorative work. If an elder's situation changes, they are highly vulnerable to a rapid onset of oral disease that can be devastating and extremely difficult to address. This manuscript reviews the role of the oral care industry in understanding this population as a market and the different approaches that might be used in promoting health. Two key market segments were identified, the vulnerable elders with high levels of chronic oral disease, systemic complications, medications and often inability to maintain good standards of oral hygiene and a wealthier, health and beauty conscious group with a keen interest in maintaining a healthy, aesthetically pleasing and functional dentition throughout their lives. It is likely that within current healthcare models, the oral care of elders will be unsustainable, with a smaller working population funding ever-increasing health care needs. 'Home care' combined with effective professional preventive and effective therapeutic options are essential.

Our previous findings have demonstrated that acupuncture at the Taixi (KI3) acupoint in healthy youths can activate neurons in cognitive-related cerebral cortex. Here, we investigated whether acupuncture at this acupoint in elderly patients with mild cognitive impairment can also activate neurons in these regions. Resting state and task-related functional magnetic resonance imaging showed that the pinprick senstation of acupuncture at the Taixi acupoint differed significantly between elderly ...

Cognitive abilities decline over the time course of our life, a process, which may be mediated by brain atrophy and enhanced inflammatory processes. Lifestyle factors, such as regular physical activities have been shown to counteract those noxious processes and are assumed to delay or possibly even prevent pathological states, such as dementing disorders. Whereas the impact of lifestyle and immunological factors and their interactions on cognitive aging have been frequently studied, their effects on neural parameters as brain activation and functional connectivity are less well studied. Therefore, we investigated 32 healthy elderly individuals (60.4 ± 5.0 SD; range 52–71 years) with low or high level of self-reported aerobic physical activity at the time of testing. A higher compared to a lower level in aerobic physical activity was associated with an increased encoding related functional connectivity in an episodic memory network comprising mPFC, thalamus, hippocampus precuneus, and insula. Moreover, encoding related functional connectivity of this network was associated with decreased systemic inflammation, as measured by systemic levels of interleukin 6. PMID:28082894

The clinical significance of imitation behaviour (IB) is unclear. The aim of this study was to investigate the prevalence of subtle naïve and obstinate IB in convenience samples of normal elderly, demented, and depressed subjects. Subtle IB was assessed using a protocol constructed ad hoc in 146 patients, consecutively referred to a memory clinic having received an ICD-10 diagnosis of either dementia or depression, and in 241 healthy subjects. The prevalence of IB in the three groups was determined and the association with possible demographic, cognitive, and non-cognitive variables analysed. Subtle naïve IB was frequent in the elderly with dementia, intermediate in the depressed, and rare in the normal elderly except that the latter frequently stretched out their arms. Obstinate IB never occurred in the normal elderly. IB was predicted by none of the variables used. The groups included were convenience samples with the depressed being a small group precluding further distinction of depressive subtypes. Although naïve IB is a frequent clinical feature in the demented, it also accompanies depressive disorders in the elderly. It can be observed as context-specific IB in the normal elderly. Obstinate IB does not occur in the normal elderly. Copyright 2006 John Wiley & Sons, Ltd.

Several evidences report that a vegetarian diet is protector against cardiovascular diseases. Few studies have demonstrated the circulating profile of cardiovascular biomarkers in vegetarians. Therefore, the aims of the current study were compared the plasma concentrations of myeloperoxidase (MPO), metalloproteinase (MMP)-9, MMP-2, tissue inhibitor of MMP (TIMP)-1 and TIMP-2 between healthy vegetarian (Veg) and healthy omnivorous (Omn). Using ELISA and multiplexed bead immunoassay, we measured in plasma from 43 Veg and 41 Omn the cardiovascular biomarkers concentrations cited above. We found significant lower concentrations of MPO, MMP-9, MMP-2 and MMP-9/TIMP-1 ratio in Veg compared to Omn (all Pvegetarian diet is associated with a healthier profile of cardiovascular biomarkers compared to omnivorous.

2018-01-01

Background This report provides data on the use of social media advertising as a clinical trial recruitment strategy targeting healthy volunteers aged 60 years and older. The social media advertising campaign focused on enrollment for a Phase 1 clinical trial. Traditional means of recruiting—billboards, newspaper advertising, word of mouth, personal referrals, and direct mail—were not producing enough qualified participants. Objective To demonstrate the effectiveness of using targeted advertising on the social networking site Facebook to recruit people aged 60 years and older for volunteer clinical trial participation. Methods The trial sponsor used a proactive approach to recruit participants using advertising on social media. The sponsor placed and monitored an Institutional Review Board-approved advertising campaign on Facebook to recruit potential candidates for a Phase 1 clinical trial. The clinical trial required a 10-day residential (overnight) stay at a clinic in Michigan, with one follow-up visit. The sponsor of the clinical trial placed the advertising, which directed interested respondents to a trial-specific landing page controlled by the Contract Research Organization (CRO). The CRO provided all follow-up consenting, prescreening, screening, and enrollment procedures. The campaign was waged over an 8-week period to supplement recruiting by the CRO. Results A total of 621 people responded to a Facebook advertising campaign by completing an online form or telephoning the CRO, and the clinical trial was fully enrolled at 45 subjects following an 8-week Facebook advertising campaign. Conclusions An 8-week Facebook advertising campaign contributed to 868 inquiries made regarding a Phase 1 clinical trial seeking to enroll healthy elderly subjects. Over the initial 11 weeks of recruitment, 178 inquiries were received using traditional methods of outreach.

Full Text Available Objectives: Here we determined the prevalence of Salmonella in cloacal swabs and pharyngeal swabs of apparently healthy pigeons sold in the live bird markets and villages in and around Bangladesh Agricultural University Campus, Mymensingh, Bangladesh. Materials and methods: A total of 50 samples, comprised of cloacal swabs (n=24 and pharyngeal swabs (n=26 were collected. The samples were processed, and Salmonella was isolated through a series of conventional bacteriological techniques and biochemical tests followed by polymerase chain reaction (PCR. Results: The prevalence rate of Salmonella was found to be 37.5% (n=9/24 in cloacal swabs and 30.77% (n=8/26 in pharyngeal swabs with an overall prevalence rate of 34% (n=17/50. The prevalence rate of Salmonella pigeon varied slightly among locations; 34.62% (n=9/26 in live bird markets, and 33.33% (n=8/24 in villages. Molecular detection of 17 Salmonella isolates obtained from biochemical test was performed by genus specific PCR, where all of them amplified a region of 496-bp segment of the histidine transport operon gene. Antibiogram study revealed multi-drug resistant traits in most of the isolates tested. The highest resistance was found against Ampicillin (88.23% followed by Cephalexin (82.35%. The rate of sensitivity of the isolates to Ciprofloxacin was 100% followed by Azithromycin (82.35%, Gentamicin (76.47% and Nalidixic acid (76.47%. Conclusion: Our findings suggest that pigeons carry multi-drug resistant Salmonella that may transfer to the humans and animals. [J Adv Vet Anim Res 2016; 3(1.000: 51-55

Achalasia in the elderly patient: a comparative study

2011-03-01

Full Text Available CONTEXT: Achalasia is a primary esophageal motor disorder secondary to the degeneration of ganglion cells of the inhibitory intramural myenteric plexus. It affects both sexes similarly and has two peaks of incidence, one in the 3rd to 4th decades of life and the other after 60 years of age. The effect of age on esophageal motility of patients with achalasia is not well known. Studies have shown that healthy older people, when compared to the young, have: a a lower number of ganglion cells in the intramural myenteric plexus; b a reduced normal relaxation of the lower esophageal sphincter; and c a reduced esophageal peristalsis. Thus, as both age and achalasia can produce comparable degenerative changes in the intramural myenteric plexus, it is possible that advanced age could be an important factor in enhancing the clinical and manometric abnormalities commonly found in patients with achalasia. OBJECTIVES: To compare the clinical, radiological and manometric findings in young as compared to elderly (>60 years old achalasia patients. METHODS: A retrospective study of a group of patients with untreated achalasia separated into young and elderly patients. Demographic, clinical, serology for Chagas' disease, radiological and manometric data were compared between these groups. The level of significance was P<0.05. RESULTS: The study included 105 patients, 52 young (25 M/27 F, mean age 40 years old and 53 elderly (21 M/32 F, mean age 70 years old. The elderly group had a higher prevalence of Chagas' disease (P = 0.004 and a lower pressure of the lower esophageal sphincter [26.4 mm Hg vs 31.9 mm Hg] P = 0.001, a difference that persisted when analyzed only elderly and young patients with idiopathic achalasia. Younger patients had a higher prevalence of heartburn (P = 0.001 and chest pain (P = 0.012 than the elderly. CONCLUSION: Elderly patients with achalasia had a lower esophageal sphincter pressure than the young, even when we excluded patients with

Full Text Available ABSTRACT Studies show that aging is accompanied by decline in cognitive functions but also indicate that interventions, such as training on electronic games, can enhance performance and promote maintenance of cognitive abilities in healthy older adults. Objective: To investigate the effects of an electronic game program, called Actively Station, on the performance of global cognition of adults aged over 50 years. Methods: 124 mature and elderly adults enrolled in the "Actively Station" cognitive stimulation program of São Caetano do Sul City, in the State of São Paulo, participated in training for learning of electronic games. Participants were divided into two groups: training group (TG n=102 and control group (CG n=22. Protocol: a sociodemographic questionnaire, the Mini-Mental State Examination (MMSE, the Addenbrooke's Cognitive Examination Revised (ACE-R, the Memory Complaint Questionnaire (MAC-Q, the scale of frequency of forgetfulness, the Geriatric Depression Scale (GDS-15, the Geriatric Anxiety Inventory (GAI, the Global Satisfaction with Life Scale, and two scales on learning in the training. Results: The cognitive performance of the TG improved significantly after the program, particularly in the domains of language and memory, and there was a decrease on the anxiety index and frequency of memory complaints, when compared to the CG. Conclusion: These findings suggest that the acquisition of new knowledge and the use of new stimuli, such as electronic games, can promote improvements in cognition and mood and reduce the frequency of memory complaints.

This study assessed usability and acute effects of a newly developed bedside console (COPHYCON. Fifteen healthy elderly individuals performed a one-time 80-min intervention, including cognitive video games aimed at improving awareness and selective attention. Perceived usefulness and perceived ease of use (Technology Acceptance Model were assessed together with measures of the achieved game level, reaction times, (in- correct responses during ALERT and SELECT game play. Further, prefrontal cortical involvement of the regional cerebral hemoglobin saturation (rS02% assessed with functional near infrared spectroscopy (fNIRS (n = 5 and EEG power (n = 10 was analyzed. All participants completed the study without any adverse events. Perceived usefulness and perceived ease of use (TAM scores range 1–7 of the system varied between 3.9 and 6.3. The game levels reached for awareness varied between 9 and 11 (initial score 8–10, for reaction speed between 439 and 469 ms, and for correct responses between 74.1 and 78.8%. The highest level for the selective attention games was 2 (initial score 1, where reaction speed varied between 439 and 469 ms, correct responses between 96.2 and 98.5%, respectively. The decrease of rS02% in the right prefrontal cortex during gameplay was significantly (p < 0.001 lower, compared to the left prefrontal cortex. Four participants yielded significant lower rS02% measures after exergaming with the ALERT games (p < 0.000, but not with the SELECT games.

Background: Processing speed training using a 1-year intervention period improves cognitive functions and emotional states of elderly people. Nevertheless, it remains unclear whether short-term processing speed training such as 4 weeks can benefit elderly people. This study was designed to investigate effects of 4 weeks of processing speed training on cognitive functions and emotional states of elderly people. Methods: We used a single-blinded randomized control trial (RCT). Seventy-two older adults were assigned randomly to two groups: a processing speed training game (PSTG) group and knowledge quiz training game (KQTG) group, an active control group. In PSTG, participants were asked to play PSTG (12 processing speed games) for 15 min, during five sessions per week, for 4 weeks. In the KQTG group, participants were asked to play KQTG (four knowledge quizzes) for 15 min, during five sessions per week, for 4 weeks. We measured several cognitive functions and emotional states before and after the 4 week intervention period. Results: Our results revealed that PSTG improved performances in processing speed and inhibition compared to KQTG, but did not improve performance in reasoning, shifting, short term/working memory, and episodic memory. Moreover, PSTG reduced the depressive mood score as measured by the Profile of Mood State compared to KQTG during the 4 week intervention period, but did not change other emotional measures. Discussion: This RCT first provided scientific evidence related to small acute benefits of 4 week PSTG on processing speed, inhibition, and depressive mood in healthy elderly people. We discuss possible mechanisms for improvements in processing speed and inhibition and reduction of the depressive mood. Trial registration: This trial was registered in The University Hospital Medical Information Network Clinical Trials Registry (UMIN000022250).

2015-12-01

Locomotor adaptability is based on the implementation of error-feedback information from previous perturbations to predictively adapt to expected perturbations (feedforward) and to facilitate reactive responses in recurring unexpected perturbations ('savings'). The effect of aging on predictive and reactive adaptability is yet unclear. However, such understanding is fundamental for the design and application of effective interventions targeting fall prevention. We systematically searched the Web of Science, MEDLINE, Embase and Science Direct databases as well as the reference lists of the eligible articles. A study was included if it addressed an investigation of the locomotor adaptability in response to repeated mechanical movement perturbations of healthy older adults (≥60 years). The weighted average effect size (WAES) of the general adaptability (adaptive motor responses to repeated perturbations) as well as predictive (after-effects) and reactive adaptation (feedback responses to a recurring unexpected perturbation) was calculated and tested for an overall effect. A subgroup analysis was performed regarding the factor age group [i.e., young (≤35 years) vs. older adults]. Furthermore, the methodological study quality was assessed. The review process yielded 18 studies [1009 participants, 613 older adults (70 ± 4 years)], which used various kinds of locomotor tasks and perturbations. The WAES for the general locomotor adaptability was 1.21 [95% confidence interval (CI) 0.68-1.74, n = 11] for the older and 1.39 (95% CI 0.90-1.89, n = 10) for the young adults with a significant (p locomotor adaptability in general and predictive and reactive adaptation in particular remain highly effective in the elderly, showing only minor, not statistically significant age-related deficits. Consequently, interventions which use adaptation and learning paradigms including the application of the mechanisms responsible for an effective predictive and reactive dynamic stability

2012-03-01

Full Text Available Abstract Background Canine vector-borne diseases (CVBDs are caused by a wide range of pathogens transmitted to dogs by arthropods including ticks and insects. Many CVBD-agents are of zoonotic concern, with dogs potentially serving as reservoirs and sentinels for human infections. The present study aimed at assessing the seroprevalence of infection with or exposure to Dirofilaria immitis, Ehrlichia canis, Borrelia burgdorferi sensu lato, Anaplasma spp. and Leishmania infantum in dogs in Portugal. Methods Based on 120 veterinary medical centres from all the regions of mainland and insular Portugal, 557 apparently healthy and 628 CVBD-suspect dogs were sampled. Serum, plasma or whole blood was tested for qualitative detection of D. immitis antigen and antibodies to E. canis, B. burgdorferi s. l., Anaplasma spp. and L. infantum with two commercial in-clinic enzyme-linked immunosorbent assay kits. Odds ratios (OR were calculated by logistic regression analysis to identify independent risk factors of exposure to the vector-borne agents. Results Total positivity levels to D. immitis, E. canis, B. burgdorferi, Anaplasma spp., L. infantum, one or more agents and mixed agents were 3.6%, 4.1%, 0.2%, 4.5%, 4.3%, 14.0% and 2.0% in the healthy group, and 8.9%, 16.4%, 0.5%, 9.2%, 25.2%, 46.3% and 11.6% in the clinically suspect group, respectively. Non-use of ectoparasiticides was a risk factor for positivity to one or more agents both in the apparently healthy (OR = 2.1 and CVBD-suspect (OR = 1.5 dogs. Seropositivity to L. infantum (OR = 7.6, E. canis (OR = 4.1 and D. immitis (OR = 2.4 were identified as risk factors for the presence of clinical signs compatible with CVBDs. Positivity to mixed agents was not found to be a risk factor for disease. Conclusions Dogs in Portugal are at risk of becoming infected with vector-borne pathogens, some of which are of zoonotic concern. CVBDs should be considered by practitioners and prophylactic measures must be put in

Elderly people are less able to manipulate objects skilfully than young adults. Although previous studies have examined age-related deterioration of hand movements with a focus on the phase after grasping objects, the changes in the reaching phase have not been studied thus far. We aimed to examine whether changes in hand shape patterns during the reaching phase of grasping movements differ between young adults and the elderly. Ten healthy elderly adults and 10 healthy young adults were examined using the Simple Test for Evaluating Hand Functions and kinetic analysis of hand pre-shaping reach-to-grasp tasks. The results were then compared between the two groups. For kinetic analysis, we measured the time of peak tangential velocity of the wrist and the inter-fingertip distance (the distance between the tips of the thumb and index finger) at different time points. The results showed that the elderly group's performance on the Simple Test for Evaluating Hand Functions was significantly lower than that of the young adult group, irrespective of whether the dominant or non-dominant hand was used, indicating deterioration of hand movement in the elderly. The peak tangential velocity of the wrist in either hand appeared significantly earlier in the elderly group than in the young adult group. The elderly group also showed larger inter-fingertip distances with arch-like fingertip trajectories compared to the young adult group for all object sizes. To perform accurate prehension, elderly people have an earlier peak tangential velocity point than young adults. This allows for a longer adjustment time for reaching and grasping movements and for reducing errors in object prehension by opening the hand and fingers wider. Elderly individuals gradually modify their strategy based on previous successes and failures during daily living to compensate for their decline in dexterity and operational capabilities. © 2017 Japanese Psychogeriatric Society.

An increase in the exposure and predisposition of civilian populations to disasters has been recorded in the last decades. In major disasters, as demonstrated recently in Nepal (2015) and previously in Haiti (2010), external aid is vital, yet in the first hours after a disaster, communities must usually cope alone with the challenge of providing emergent lifesaving care. Communities therefore need to be prepared to handle emergency situations. Mapping the needs of the populations within their purview is a trying task for decision makers and community leaders. In this context, the elderly are traditionally treated as a susceptible population with special needs. The current study aimed to explore variations in the level of community resilience along the lifespan. The study was conducted in nine small to mid-size towns in Israel between August and November 2011 (N = 885). The Conjoint Community Resiliency Assessment Measure (CCRAM), a validated instrument for community resilience assessment, was used to examine the association between age and community resilience score. Statistical analysis included spline and logistic regression models that explored community resiliency over the lifespan in a way that allowed flexible modeling of the curve without prior constraints.

Full Text Available An increase in the exposure and predisposition of civilian populations to disasters has been recorded in the last decades. In major disasters, as demonstrated recently in Nepal (2015 and previously in Haiti (2010, external aid is vital, yet in the first hours after a disaster, communities must usually cope alone with the challenge of providing emergent lifesaving care. Communities therefore need to be prepared to handle emergency situations. Mapping the needs of the populations within their purview is a trying task for decision makers and community leaders. In this context, the elderly are traditionally treated as a susceptible population with special needs. The current study aimed to explore variations in the level of community resilience along the lifespan. The study was conducted in nine small to mid-size towns in Israel between August and November 2011 (N = 885. The Conjoint Community Resiliency Assessment Measure (CCRAM, a validated instrument for community resilience assessment, was used to examine the association between age and community resilience score. Statistical analysis included spline and logistic regression models that explored community resiliency over the lifespan in a way that allowed flexible modeling of the curve without prior constraints. This innovative statistical approach facilitated identification of the ages at which trend changes occurred. The study found a significant rise in community resiliency scores in the age groups of 61-75 years as compared with younger age bands, suggesting that older people in good health may contribute positively to building community resiliency for crisis. Rather than focusing on the growing medical needs and years of dependency associated with increased life expectancy and the resulting climb in the proportion of elders in the population, this paper proposes that active "young at heart" older people can be a valuable resource for their community.

Community-dwelling older adults are at risk for declines in physical health, cognition, and psychosocial well-being. However, their enactment of active and health-promoting lifestyles can reduce such declines. The purpose of this article is to describe the USC Well Elderly II study, a randomized clinical trial designed to test the effectiveness of a healthy lifestyle program for elders, and document how various methodological challenges were addressed during the course of the trial. In the study, 460 ethnically diverse elders recruited from a variety of sites in the urban Los Angeles area were enrolled in a randomized experiment involving a crossover design component. Within either the first or second 6-month phase of their study involvement, each elder received a lifestyle intervention designed to improve a variety of aging outcomes. At 4-5 time points over an 18-24 month interval, the research participants were assessed on measures of healthy activity, coping, social support, perceived control, stress-related biomarkers, perceived physical health, psychosocial well-being, and cognitive functioning to test the effectiveness of the intervention and document the process mechanisms responsible for its effects. The study protocol was successfully implemented, including the enrollment of study sites, the recruitment of 460 older adults, administration of the intervention, adherence to the plan for assessment, and establishment of a large computerized data base. Methodological challenges were encountered in the areas of site recruitment, participant recruitment, testing, and intervention delivery. The completion of clinical trials involving elders from numerous local sites requires careful oversight and anticipation of threats to the study design that stem from: (a) social situations that are particular to specific study sites; and (b) physical, functional, and social challenges pertaining to the elder population.

BACKGROUND. Although postprandial hypotension is a common cause of falls and syncope in elderly persons and in patients with autonomic insufficiency, the pathophysiology of this disorder remains unknown. METHODS AND RESULTS. We examined the hemodynamic, splanchnic blood pool, plasma norepinephrine (NE), and heart rate (HR) power spectra responses to a standardized 400-kcal mixed meal in 11 healthy young (age, 26 +/- 5 years) and nine healthy elderly (age, 80 +/- 5 years) subjects and 10 dysautonomic patients with symptomatic postprandial hypotension (age, 65 +/- 16 years). Cardiac and splanchnic blood pools were determined noninvasively by radionuclide scans, and forearm vascular resistance was determined using venous occlusion plethysmography. In healthy young and old subjects, splanchnic blood volume increased, but supine blood pressure remained unchanged after the meal. In both groups, HR increased and systemic vascular resistance remained stable. Forearm vascular resistance and cardiac index increased after the meal in elderly subjects, whereas these responses were highly variable and of smaller magnitude in the young. Young subjects demonstrated postprandial increases in low-frequency HR spectral power, representing cardiac sympatho-excitation, but plasma NE remained unchanged. In elderly subjects, plasma NE increased after the meal but without changes in the HR power spectrum. Patients with dysautonomia had a large postprandial decline in blood pressure associated with no change in forearm vascular resistance, a fall in systemic vascular resistance, and reduction in left ventricular end diastolic volume index. HR increased in these patients but without changes in plasma NE or the HR power spectrum. CONCLUSIONS. 1) In healthy elderly subjects, the maintenance of blood pressure homeostasis after food ingestion is associated with an increase in HR, forearm vascular resistance, cardiac index, and plasma NE. In both young and old, systemic vascular resistance is

Normal ageing is often accompanied by loss of appetite and decrease in food intake. Weight loss of senescence is called anorexia of ageing. As an outstanding scientist and physician of Traditional Persian Medicine, Avicenna has introduced an unconventional approach to seniors. He also believed that the elderly should consider special schemes in order to maintain their health. These schemes include consideration of nutrition, mental states, sleep, bathing, and physical activities, and even choosing some appropriate hobbies. The elderly should consume foods and fruits with laxative and stool-softening properties to prevent constipation. They would also do better to decrease the amount of food eaten at meals, but at the same time increasing the number of meals to compensate for low food intake. Moreover, they should maintain their vital force and avoid any activities that tax the body. Furthermore, considering the principles of hifz-al-sehah can help secure long and healthy lives for the elderly.

Aging is a degenerative process marked by recognized functional, physiological, and metabolic impairments, such as dynapenia and diminished cognitive capacity. Therefore, the search for innovative strategies to prevent/delay these physiological and cognitive disorders is essential to guarantee the independence and life quality of an elderly population. The aim of this work is to verify the effect of a 12-week resistance exercise program on the general physical aptitude and cognitive capacities of elderly and sedentary women. Twenty-nine women (65.87±5.69 years) were divided into two groups. The control group was composed of eight elderly women who met the same inclusion criteria of the study and the strength training group was composed of 29 elderly women who were subjected to a resistance exercise program defined by 12 upper and lower limb exercises combined in 3×10 repetitions with 1-minute interval between repetitions and two resting minutes between exercises (three times/week). Weight loads were fixed between 60% and 75% of the apparent 1 repetition maximum, which was estimated by the test of 10 maximum repetitions. The direct curl was performed for upper body strength evaluation with 2.3 kg dumbbells for 30 seconds, whereas the chair test was used for lower body evaluation (total sit-stand movements in 30 seconds). The cognitive capacities of subjects were evaluated by "The Montreal Cognitive Assessment" questionnaire. After 12 weeks, the elderly group showed significant increases in the average upper body strength (58%), lower body strength (68%), and cognitive capacity (19%). The present study demonstrated that regular resistance exercises could provide significant gains on the upper and lower body strength concomitant to positive improvements on cognitive capacities of elderly women, bringing enhanced life quality.

Full Text Available The aim of the study was to determine the effect of a resistance training program in hemodynamic responses and adaptations in 60 yr. old elderly. Volunteers were 60 healthy-elderly who underwent a training program 3 times/wk. for 12 wk. Participants were randomly assigned to either a control group, an exercise group who trained at 30% intensity of 5 maximal repetitions (5RM (30% of 5RM or an exercise group at an intensity of 70% (70% of 5RM. Hemodynamic variables measured were mean arterial pressure (MAP, calculated before and immediately after the training session, and rate pressure product (RPP, estimated once a month and before and after finishing the program. Results indicated that resistance exercise training at 30% and 70% of 5RM, with a total exercise work of 872.7 and 890.9 kg did not elicited cardiovascular risks for the elderly. A 12-wk resistance exercise training reduced the cardiovascular strain as shown by the RPP (~16% and the MAP (~9%, with no adverse effects throughout the program. Unfortunately, all the hemodynamic benefits were reverted 6 days following completion of the program. In conclusion, a healthy elderly population must perform resistance training exercises to significantly reduce the cardiovascular stress. We suggest to conduct further research that looks into different exercise intensities in longer program duration and to determine the mechanisms responsible for the deleterious effects of the detraining by using physiological, biochemical and biomechanical variables.

The field of space medicine is responsible for maintaining astronauts’ health and optimizing their performance. A prolonged stay in space with little gravity results in weakening of the bones and muscles that otherwise support body weight, which is precisely the problem faced by elderly people on Earth. Space medicine provides the means of alleviating such problems. Bone loss, muscle atrophy, and disturbed circadian rhythms are common issues for both astronauts and the elderly alike and can be prevented, if the risks are addressed correctly. To have a healthy long-life, it is important to practice effective health improvement techniques and take preventive measures. The space medicine technologies a for astronauts will provide helpful information to people living in a super aging society. and Japanese medical societies for health promotion. With the aids of the Japanese Society of Physical Fitness and Sports Medicine, the Japanese Orthopaedic Association, and the Japanese Association of Rehabilitation Medicine, JAXA has made a leaflet titled for general citizen to show the tips for a healthy long-life learned from space medicine from the viewpoints of their respective expertise.

Health status of Hispanic elders.

Bassford, T L

Hispanic elders living in the United States compose a rapidly increasing population. They are underinsured and more likely to be living in poverty. Health care is hindered in this population by lower access to health services and less use of preventive services. Barriers to access are primarily socioeconomic. Acculturation exerts an effect, primarily through its association with language skills, employment, and education. Cardiovascular disease is the leading cause of mortality for Hispanics, who have a higher prevalence of risk factors for cardiovascular disease, such as diabetes mellitus, obesity, and hyperlipidemia. Although neoplasia is the second most frequent cause of death among Hispanics, as it is in whites who are not Hispanic, Hispanics have an overall lower cancer rate. Cancer rates are increasing, however. Non-insulin-dependent diabetes mellitus is a significant cause of morbidity and mortality in the Hispanic population, affecting nearly a quarter of adult Puerto Ricans and Mexican Americans. Although higher prevalence of obesity in the Hispanic population accounts for some of this difference, some data suggest the possibility of a genetic component as well. Assessment of psychological health in Hispanic elders is impeded by the lack of instruments designed for this population. Distress is often expressed as somatic symptoms. Values traditional to Hispanic culture, such as respeto, allocentrism, and familialism, are important to US Hispanic elders, many of whom were born in rural Mexico. Our knowledge of determinants of healthy aging in this population is still preliminary, but rapidly expanding, in part, because of increased attention to ethnicity in health reporting.

The delivery of efficient nonpharmacological treatment to prevent the loss of muscle mass in older adults is a major challenge, and information on the combined effects of training and diet is particularly important. Here we aimed to evaluate the effects of 24 wk of resistance training combined with a healthy dietary approach (n-6/n-3 ratio healthy and physically active older women (65-70 years). The three-armed randomized controlled trial included a resistance training + healthy diet group (RT-HD), a resistance training group (RT), and controls (CON). All subjects included in the study were physically active and had low levels of serum inflammatory markers. In accordance with the dietary goals, the n-6/n-3 ratio dietary intake significantly decreased only in RT-HD by 42%. An increase in 1 repetition maximum in leg extension occurred in RT (+20.4%) and RT-HD (+20.8%), but not in CON. Interestingly, leg lean mass significantly increased only in RT-HD (+1.8%). While there were no changes in serum C-reactive protein and IL-6 levels, a significant decrease in serum level of the pro-inflammatory precursor arachidonic acid (-5.3 ± 9.4%) together with an increase in serum n-3 docosahexaenoic acid (+8.3%) occurred only in RT-HD. Altogether, this study demonstrates that the effects of resistance training on muscle mass in healthy older adults can be optimized by the adoption of a healthy diet.

As humans age or are influenced by pathology of the neuromuscular system, gait patterns are known to adjust, accommodating for reduced function in the balance control system. The aim of this study was to investigate the effectiveness of a wavelet based multiscale analysis of a gait variable [minimum toe clearance (MTC)] in deriving indexes for understanding age-related declines in gait performance and screening of balance impairments in the elderly. MTC during walking on a treadmill for 30 healthy young, 27 healthy elderly and 10 falls risk elderly subjects with a history of tripping falls were analyzed. The MTC signal from each subject was decomposed to eight detailed signals at different wavelet scales by using the discrete wavelet transform. The variances of detailed signals at scales 8 to 1 were calculated. The multiscale exponent (beta) was then estimated from the slope of the variance progression at successive scales. The variance at scale 5 was significantly (ppathological conditions. Early detection of gait pattern changes due to ageing and balance impairments using wavelet-based multiscale analysis might provide the opportunity to initiate preemptive measures to be undertaken to avoid injurious falls.

Exercise training and physical activity (PA) have substantial vascular and cardiac health benefits. Ikaria Island has been recognised as having one of the highest longevity rates worldwide and a high percentage of healthy ageing. We examined the relationship between endothelial function and levels of habitual PA to evaluate the factors related to healthy ageing in this population. The study was conducted on a subgroup population of the IKARIA study consisting of 185 middle-aged (40-65 years) and 142 elderly subjects (66-91 years). Endothelial function was evaluated by ultrasound measurement of flow-mediated dilatation (FMD). PA was evaluated using the shortened version of the self-reported International Physical Activity Questionnaire (IPAQ). Subjects in the low PA group (physically inactive and the rest as active. In the overall study population FMD was inversely associated with age (r=-0.24, pphysically active had higher FMD compared with the physically inactive. Physically active subjects in the middle-aged group showed higher FMD compared with the physically active elderly (p=0.008). However, there was no difference in FMD values between middle-aged inactive subjects and the elderly physically active (p=NS). The present study revealed that increased PA was associated with improved endothelial function in middle-aged subjects and that PA in elderly subjects can ameliorate the devastating effects of ageing on arterial wall properties.

Despite the apparent age-related decline in perceptual-motor performance, recent studies suggest that the elderly people can improve their reaction time when relevant sensory information are available. However, little is known about which sensory information may improve motor behaviour itself. Using a synchronization task, the present study investigates how visual and/or auditory stimulations could increase accuracy and stability of three bimanual coordination modes produced by elderly and young adults. Neurophysiological activations are recorded with ElectroEncephaloGraphy (EEG) to explore neural mechanisms underlying behavioural effects. Results reveal that the elderly stabilize all coordination modes when auditory or audio-visual stimulations are available, compared to visual stimulation alone. This suggests that auditory stimulations are sufficient to improve temporal stability of rhythmic coordination, even more in the elderly. This behavioural effect is primarily associated with increased attentional and sensorimotor-related neural activations in the elderly but similar perceptual-related activations in elderly and young adults. This suggests that, despite a degradation of attentional and sensorimotor neural processes, perceptual integration of auditory stimulations is preserved in the elderly. These results suggest that perceptual-related brain plasticity is, at least partially, conserved in normal aging. Copyright © 2014 Elsevier B.V. All rights reserved.

To estimate the prevalence of unknown impaired glucose metabolism, also referred to as prediabetes (PreD), and unknown type 2 diabetes mellitus (T2DM) among subjectively healthy Swiss senior citizens. The fasting plasma glucose (FPG) and glycated haemoglobin A(1c) (HbA(1c)) levels were used for screening. A total of 1 362 subjects were included (613 men and 749 women; age range 60-99 years). Subjects with known T2DM were excluded. The FPG was processed immediately for analysis under standardised preanalytical conditions in a cross-sectional cohort study; plasma glucose levels were measured by means of the hexokinase procedure, and HbA(1c) was measured chromatographically and classified using the current American Diabetes Association (ADA) criteria. The crude prevalence of individuals unaware of having prediabetic FPG or HbA(1c) levels, was 64.5% (n = 878). Analogously, unknown T2DM was found in 8.4% (n = 114) On the basis of HbA(1c) criteria alone, significantly more subjects with unknown fasting glucose impairment and laboratory T2DM could be identified than with the FPG. The prevalence of PreD as well as of T2DM increased with age. The mean HOMA indices (homeostasis model assessment) for the different age groups, between 2.12 and 2.59, are consistent with clinically hidden disease and are in agreement with the largely orderly Body Mass Indices found in the normal range. Laboratory evidence of impaired glucose metabolism and, to a lesser extent, unknown T2DM, has a high prevalence among subjectively healthy older Swiss individuals. Laboratory identification of people with unknown out-of-range glucose values and overt diabetic hyperglycaemia might improve the prognosis by delaying the emergence of overt disease.

We studied the population of noninstitutionalized elderly persons in Iowa County, Iowa, who had not used a well-elderly clinic offering free home or clinic assessments by a nurse. Questionnaires were administered by trained interviewers to a sample of the nonuser population, 60 years of age and over (n = 360). Fifty-five percent did not know that there was a well-elderly clinic in the county in spite of widespread advertising. Nonusers who had heard of the clinic were more highly educated and had more transportation problems than nonusers who were aware of the clinic. Sixty percent of those who saw no point in going to a doctor if they were feeling well were unaware of the clinic. Nonusers tended to be older, living on farms, mobile, long-time residents, and 54 percent had less than a high school education. The cost of health care was not a problem. The major reason given for not using the clinic was that the person was "under a doctor's care." Those who had no regular doctor did not plan to use the clinic because they felt healthy.

Full Text Available Although Lactobacillus rhamnosus GG ATCC 53103 (LGG has been consumed by 2 to 5 million people daily since the mid 1990s, there are few clinical trials describing potential harms of LGG, particularly in the elderly.The primary objective of this open label clinical trial is to assess the safety and tolerability of 1×1010 colony forming units (CFU of LGG administered orally twice daily to elderly volunteers for 28 days. The secondary objectives were to evaluate the effects of LGG on the gastrointestinal microbiome, host immune response and plasma cytokines.Fifteen elderly volunteers, aged 66-80 years received LGG capsules containing 1×1010 CFU, twice daily for 28 days and were followed through day 56. Volunteers completed a daily diary, a telephone call on study days 3, 7 and 14 and study visits in the Clinical Research Center at baseline, day 28 and day 56 to determine whether adverse events had occurred. Assessments included prompted and open-ended questions.There were no serious adverse events. The 15 volunteers had a total of 47 events (range 1-7 per volunteer, 39 (83% of which were rated as mild and 40% of which were considered related to consuming LGG. Thirty-one (70% of the events were expected, prompted symptoms while 16 were unexpected events. The most common adverse events were gastrointestinal (bloating, gas, and nausea, 27 rated as mild and 3 rated as moderate. In the exploratory analysis, the pro-inflammatory cytokine interleukin 8 decreased during LGG consumption, returning towards baseline one month after discontinuing LGG (p = 0.038 while there was no difference in other pro- or anti-inflammatory plasma cytokines.Lactobacillus rhamnosus GG ATCC 53103 is safe and well tolerated in healthy adults aged 65 years and older.ClinicalTrials.gov NCT 01274598.

Full Text Available Type II diabetes (TIIDM is characterized by high levels of blood glucose followed by excessive insulin release so that the target cells become less sensitive, developing insulin resistance and maintaining hyperglycemic levels. Physical activity is the strongest element to prevent and to manage the TIIDM, and the majority of patients do not remain in regularly active levels, because the premature fatigue in these patients decreases the adherence to the training. Contrastingly, the whole body vibration (WBV training may improve the glucose metabolism in diabetic patients, reducing the peripheral blood sugar, decreasing the physical discomfort and perceived exertion. Therefore, the purpose of the study was to determine the effect of an acute WBV session as therapy to promote fasting decreases in insulin levels in peripheral blood in TIIDM when compared to healthy elderly. For this, fifteen healthy elderly women and fourteen diabetic elderly women, all sedentary, were allocated in diabetic or control groups, and we made an acute whole body session composed of 10 bouts lasting 2 minutes each one, separated by a 30-second rest period. The WBV was executed in a triaxial platform MY3 Power Plate® at 35 hertz and has been chosen a peak-to-peak displacement of 4 millimeters. After the protocol, both groups decreased the glycemic levels and increased lactate production in relation to the basal levels and when compared diabetic and control, where the most important results have been shown in diabetic women. This study revealed that WBV training in TIIDM has had significant beneficial effects on the control of glucose levels, still in an acute session. So that, the complete training probably will show better results about glycemic control and this finding could be especially important when prescribing exercise for elderly who are unable or unwilling to use traditional loads or who show poor exercise compliance.

Extraversion and neuroticism are two important and frequently studied dimensions of human personality. They describe individual differences in emotional responding that are quite stable across the adult lifespan. Neuroimaging research has begun to provide evidence that neuroticism and extraversion have specific neuroanatomical correlates within the cerebral cortex and amygdala of young adults. However, these brain areas undergo alterations in size with aging, which may influence the nature of these personality factor-brain structure associations in the elderly. One study in the elderly demonstrated associations between perisylvian cortex structure and measures of self transcendence [Kaasinen, V., Maguire, R.P., Kurki, T., Bruck, A., Rinne, J.O., 2005. Mapping brain structure and personality in late adulthood. NeuroImage 24, 315-322], but the neuroanatomical correlates of extraversion and neuroticism, or other measures of the Five Factor Model of personality have not been explored. The purpose of the present study was to investigate the structural correlates of neuroticism and extraversion in healthy elderly subjects (n=29) using neuroanatomic measures of the cerebral cortex and amygdala. We observed that the thickness of specific lateral prefrontal cortex (PFC) regions, but not amygdala volume, correlates with measures of extraversion and neuroticism. The results suggest differences in the regional neuroanatomic correlates of specific personality traits with aging. We speculate that this relates to the influences of age-related structural changes in the PFC.

In order to compare the physiological and the subjective responses to low relative humidity of elderly and young men, we measured saccharin clearance time (SCT), frequency of blinking, hydration state of the skin, transepidermal water loss (TEWL), sebum level recovery and skin temperatures as physiological responses. We asked subjects to evaluate thermal, dryness and comfort sensations as subjective responses using a rating scale. Eight non-smoking healthy male students (21.7+/-0.8 yr) and eight non-smoking healthy elderly men (71.1+/-4.1 yr) were selected. The pre-room conditions were maintained at an air temperature (Ta) of 25 degrees C and a relative humidity (RH) of 50%. The test-room conditions were adjusted to provide 25 degrees C Ta and RH levels of 10%, 30% and 50%. RH had no effect on the activity of the sebaceous gland or change of mean skin temperature. SCT of the elderly group under 10% RH was significantly longer than that of the young group. In particular, considering the SCT change, the nasal mucous membrane seems to be affected more in the elderly than in the young in low RH. Under 30% RH, the eyes and skin become dry, and under 10% RH the nasal mucous membrane becomes dry as well as the eyes and skin. These findings suggested that to avoid dryness of the eyes and skin, it is necessary to maintain greater than 30% RH, and to avoid dryness of the nasal mucous membrane, it is necessary to maintain greater than 10% RH. On the thermal sensation of the legs, at the lower humidity level, the elderly group felt cooler than the young group. On the dry sensation of the eyes and throat, the young group felt drier than the elderly group at the lower humidity levels. From the above results, the elderly group had difficulty in feeling dryness in the nasal mucous membrane despite being easily affected by low humidity. On the other hand, the young group felt the change of humidity sensitively despite not being severely affected by low humidity. Ocular mucosa and

Full Text Available Severe aortic stenosis (AS is associated with the reduction of muscle mass and may be associated with deterioration of nutritional status. Furthermore, malnourished cardiac patients are characterized by a higher risk of postoperative complications and mortality. The aim of this study was the evaluation and comparison of nutritional status, appetite and body composition in older people with severe aortic stenosis before aortic valve replacement and healthy elderly volunteers. One hundred and one patients, aged >65 years old with severe AS were included in the study. Nutritional status was assessed. Body composition was estimated using bioelectrical impedance analysis. Concentrations of albumin, prealbumin, triglycerides, total cholesterol and C-reactive protein were measured, and a complete blood count was done. About 40% of AS patients were at risk of malnutrition. They had decreased hand grip strength and they lost more body mass than the control group. Malnourished AS patients were older, had lower body mass indexes (BMIs and lower aortic valve areas in comparison to well-nourished patients. Older AS patients, like their peers, show excessive body mass and, at the same time, the features of malnutrition. They have additional factors such as unintentional weight lost and decreased muscle strength which may be associated with worse outcomes.

Introduction The purpose of this study was to elucidate the impact of specific cognitive functions on self-restricted driving habits in healthy elderly drivers and patients suffering from mild cognitive impairment (MCI) and Alzheimer's dementia (AD). Method Our study population included 35 cognitively healthy controls, 10 MCI patients, and 16 patients with AD. All participants completed a neuropsychological examination and a self-reported questionnaire assessing driving habits and patterns. Results In challenging driving conditions, patients with MCI or AD showed significantly more driving self-restriction than healthy subjects (effect size d=1.06, p=0.007). Ordinal regression analysis across the entire group revealed that deficits in executive functions and reaction had a higher impact on driving restriction (p=0.002) than deficits in memory functions (p=0.570). Additionally, our data showed that 40% of patients with mild to moderate AD still drive in challenging conditions. Discussion Our results illustrate that elderly individuals use self-imposed driving restrictions as compensatory strategies. These restrictions increase with cognitive decline mainly in the field of executive functions, but they do not change once patients convert from MCI to AD. © Georg Thieme Verlag KG Stuttgart · New York.

Ageing impairs balance, which increases the risk of falls. Fall-related injuries are a serious health problem associated with dependency and disability in the elderly and results in high costs to public health systems. This study aims to determine the effects of a training program to develop balance using a new device called the T-Bow. A total of 28 women > 65 years were randomly assigned to an experimental group (EG) (n = 18; 69.50 [0.99] years), or a control group (CG) (n = 10; 70.70 [2.18] years). A program for lower limbs was applied for 8 weeks using 5 exercises on the T-Bow: squat, lateral and frontal swings, lunges, and plantarflexions. The intensity of the exercises was controlled by time of exposure, support base, and ratings of perceived exertion. Clinical tests were used to evaluate variables of balance. Static balance was measured by a 1-leg balance test (unipedal stance test), dynamic balance was measured by the 8-foot-up-and-go test, and overall balance was measured using the Tinetti test. Results for the EG showed an increase of 35.2% in static balance (P 0.05). Results for the CG showed a decline of 5.79% in static balance (P > 0.05) but no change in the other balance variables. Thus the data suggest that implementing a training program using the T-Bow could improve balance in healthy older women.

Full Text Available This study uses means-end chain (MEC techniques to examine the awareness, decision-making procedure, and personal values of the elderly with regard to virtual reality leisure activities. The results of the study show that elderly respondents value virtual reality leisure activities that are fun, safe, and easy. In terms of outcome benefits, elderly respondents value feeling physically and mentally healthy, firsthand experience, and satisfied curiosity. In value terms, elderly respondents hope that their chosen virtual reality leisure activities improve not only their relationships with others, but also their enjoyment, quality of life, and sense of belonging. The results show that, while consumers with different awarenesses of virtual reality leisure activities have different decision-making processes, they share creating “good memories” as the terminal value with the most significant effect. This presents a potential opportunity to promote virtual reality leisure activities. Relevant bodies or enterprises can seek to create good memories in consumers by developing activities that are safe and fun, promote good health, and provide good service, thereby attracting the interest of elderly consumers.

Full Text Available Background: In line with health promotion plans, early intervention and fall prevention in geriatric population, it is important to study healthy individuals balance mechanisms. The aim of this research was to investigate the effect of adding and removing visual input and dual task on elderly balance. Methods: Twenty healthy elderly recruited from four different senior citizen health club centers and from the University of Social Welfare and Rehabilitation Sciences (USWR participated in this analytic cross-sectional study. At USWR’s Motor Control Laboratory, the participants’ postural sway were assessed using force plate in 4 distinct double leg standing conditions with and without presence of visual input and Stroop dual task. Postural and Stroop variables were compared. Results: Findings indicated that when the elderly encountered with either dual task or absence of visual input, they can still manage the situation in a way that changes in sway parameter would not become significant. But, when these two conditions occurred simultaneously, the participant’s balance strategy fluctuated. Therefore, the mean velocity showed a significant difference between the "single quiet standing" condition and the condition of standing with eyes closed while the participants were answering Stroop dual task (Mean difference = -0.007, 95% CI = -0.012, -0.002. Conclusion: It appears that velocity parameter is sensitive to small changes, so it is recommended that researchers include this parameter in their future analyses. Balance in elderly can be manipulated by dual task and visual input deprivation.

Elder abuse is a prevalent phenomenon resulting in physical, emotional, and social costs to individuals, families, and society. Timely and effective intervention is crucial because victims are often involved in relationships where re-victimization is common. Most elder abuse victims, however, are reluctant to seek help from outside their families. The aim of the present study is to explore factors associated with help-seeking behaviors among mistreated elders in Hong Kong. In-depth interviews were conducted with 40 elder abuse survivors. Although almost all of the participants could provide some examples of elder abuse, most denied that their own experience was abusive. Personal and professional social networks were important determinants of help seeking. Social isolation, cultural barriers, self-blame, and lack of knowledge were major barriers to help seeking. © The Author(s) 2014.

Few epidemiological studies have assessed the relationship between the traditional Japanese dietary pattern and longitudinal changes in cardiovascular disease risk factors among Japanese people. We designed a 3-year longitudinal study of 980 subjects living in Japan to evaluate how the Japanese dietary pattern is related to longitudinal changes in well-recognized risk factors for cardiovascular disease among apparently healthy Japanese adults. Dietary consumption was assessed via a validated food frequency questionnaire. Principal component analysis was used to derive three major dietary patterns-"Japanese," "sweets-fruits-cooked wheaten food," and "Izakaya (Japanese Pub)" from 39 food groups. After adjustment for potential confounders, the mean (95% confidence interval) for the change per year in diastolic blood pressure for men, systolic blood pressure, and diastolic blood pressure for women related to the "Japanese" dietary pattern factor score tertiles were 0.89 (0.10, 1.68), 2.25 (0.19, 4.31), and 0.75 (-1.00, 2.50) for the lowest tertile, 0.77 (-0.02, 1.56), 1.01 (-1.13, 3.15), and 0.44 (-1.38, 2.26) for the middle tertile and - 0.04 (-0.81, 0.72), -0.48 (-2.52, 1.56), and -0.77 (-2.51, 0.96) for the highest tertile (trend P value = 0.03, pattern factor score tertiles and the longitudinal change in serum triglyceride concentration only in men (trend P value = 0.02). Greater adherence to a traditional Japanese diet was independently related to a decreased change every year in diastolic blood pressure in men and women and in systolic blood pressure in women over a 3-year follow-up period. The findings suggest that the "Japanese" dietary pattern appeared to be related to a fall in blood pressure, which might have a beneficial effect on cardiovascular disease. A randomized trial is required to clarify the underlying mechanism.

The influence of cognitive factors on financial capacity across the dementia spectrum of cognitive aging, Alzheimer's disease (AD), and mild cognitive impairment (MCI) has been little investigated, while it has not been investigated at all in other types of dementia as well as in extended samples of elders in Greece. The aim of this study is to investigate financial capacity, to develop a tool, test its psychometric properties, validate, and then test the tool in groups of healthy controls compared to elders with dementia, while examining other facets of their cognitive performance. 719 elders from Greece including healthy participants and patients with different types of dementia were examined with Legal Capacity for Property Law Transactions Assessment Scale (LCPLTAS) and a battery of neuropsychological tests concerning various cognitive functions. Significantly different profiles in the scores and subscores of LCPLTAS for all the groups of dementia patients were found, with a general incapacity finding for all the dementia groups including the MCI patients. Logistic regression showed that Mini-Mental State Examination (MMSE), Geriatric Depression Scale, and Trail Making Part B predicted competence on LCPLTAS for the dementia patients. Persons with MCI and dementia had lower financial knowledge scores than those without cognitive impairment, with MMSE scores below 27 suggestive as an indication of financial incapacity. The LCPLTAS provides information for a strong positive correlation with MMSE, while the use both of MMSE and LCPLTAS as adequate measures of financial (in)capacity is discussed for the Greek legal procedures regarding elder guardianship cases.

Full Text Available Aims. This study was to evaluate the association of serum vaspin concentrations with body mass index (BMI among elderly patients (>60 years old. Methods. A total of 227 elderly individuals included 76 healthy with normal glucose tolerance, which divided into normal weight control (BMI BMI ≥ 25, n=52, and obese diabetes (BMI ≥ 30, n=43 subgroups. Relevant parameters were matched for age and gender ratio. Serum vaspin concentrations were measured by enzyme-linked immunosorbent assay. Results. Serum vaspin concentration was significantly higher in the T2DM than the healthy (451.9±32.6 versus 284.2±21.7, P<0.01. In the diabetic patients, the vaspin concentration was significantly higher in the obese group than the normal weight group (498.2±17.1 versus 382.1±21.3, P<0.05. In addition, the concentration of vaspin in normal weight T2DM was higher than in healthy control group with normal weight (382.1±21.3 versus 192.5±45.2, P<0.05. Multiple regression analysis revealed that BMI was independent factors influencing the serum vaspin concentration in all participants. Conclusion. Vaspin may play an important compensatory role in obesity and insulin resistance in elderly people. The clinical trial registration number is ChiCTR-OPC-14005698.

Full Text Available This paper presents an autobiographical and biographical historical account of the genesis, evolution and resolution of the Elder Problem. It begins with John W. Elder and his autobiographical story leading to his groundbreaking work on natural convection at Cambridge in the 1960’s. His seminal work published in the Journal of Fluid Mechanics in 1967 became the basis for the modern benchmark of variable density flow simulators that we know today as “The Elder Problem”. There have been well known and major challenges with the Elder Problem model benchmark—notably the multiple solutions that were ultimately uncovered using different numerical models. Most recently, it has been shown that the multiple solutions are indeed physically realistic bifurcation solutions to the Elder Problem and not numerically spurious artefacts. The quandary of the Elder Problem has now been solved—a major scientific breakthrough for fluid mechanics and for numerical modelling. This paper—records, reflections, reminiscences, stories and anecdotes—is an historical autobiographical and biographical memoir. It is the personal story of the Elder Problem told by some of the key scientists who established and solved the Elder Problem. 2017 marks the 50 year anniversary of the classical work by John W. Elder published in Journal of Fluid Mechanics in 1967. This set the stage for this scientific story over some five decades. This paper is a celebration and commemoration of the life and times of John W. Elder, the problem named in his honour, and some of the key scientists who worked on, and ultimately solved, it.

2015-01-01

The role of hydration in the maintenance of health is increasingly recognized. Hydration requirements vary for each person, depending on physical activity, environmental conditions, dietary patterns, alcohol intake, health problems, and age. Elderly individuals have higher risk of developing dehydration than adults. Diminution of liquid intake and increase in liquid losses are both involved in causing dehydration in the elderly. The water used for drinking is provided through regular public water supply and the official sanitary controls ensure their quality and hygiene, granting a range of variation for most of its physical and chemical characteristics, being sometimes these differences, though apparently small, responsible for some disorders in sensitive individuals. Hence, the advantages of using bottled water, either natural mineral water or spring water, are required by law to specify their composition, their major components, and other specific parameters. It is essential to take this into account to understand the diversity of indications and favorable effects on health that certain waters can offer.

The influence of schooling on working memory performance in elderly individuals without cognitive decline

Juliana Nery de Souza-Talarico

Full Text Available Abstract Over recent decades, research on cognition has been developed rapidly toward better understanding the cognitive changes that usually occur during normal aging. There is evidence that elderly individuals have worse working memory performance than young adults. However, the effect of education on this cognitive function remains unclear. Objectives: To analyze the performance of healthy elderly subjects on working memory tasks and to verify the influence of educational level on this performance. Methods: Forty elderly individuals without cognitive impairment and fully independent, were randomly chosen from a group of subjects participating in cultural activities at the university campus. The Digit Span Forward (DSF test was used to evaluate attention performance. The working memory performance was assessed by the Digit Span Backward (DSB and the difference between DSF and DSB. The data were statistically analyzed using the Spearman's correlation coefficient to verify the correlation between the Digit Span (DS scores and the variables age and schooling, while the Multiple Linear Regression Model was used to verify the effect of these variables on the DS scores. Results: A significant positive correlation (r=0.41, p<0.01 as well as a significant association (b=0.506; p=0.001; CI 95%= 0.064/0.237 were found between years of schooling and DSB scores. It was not observed statistical correlation (r= -0.08, p=0.64 or association (b=0.41; p=0.775; CI 95%= -0.049/0.065 between age and DSB scores. Conclusion: In this study, higher levels of schooling were associated with better working memory performance in cognitively healthy elders.

Balance performance in the elderly is related to psychological factors such as attentional focus. We investigated the effects of internal vs. external focus of attention and fall history on walking stability in healthy older adults. Walking stability of twenty-eight healthy older adults was assessed by applying random unilateral decelerations on a split-belt treadmill and analysing the resulting balance recovery movements. The internal focus instruction was: concentrate on the movement of your legs, whereas the external focus instruction was: concentrate on the movement of the treadmill. In both conditions participants were asked to look ahead at a screen. Outcome measures were coefficient of variation of step length and step width, and characteristics of the centre of mass velocity time-series as analysed using statistical parametric mapping. Fall history was assessed using a questionnaire. After each perturbation participants required two to three strides to regain a normal gait pattern, as determined by the centre of mass velocity response. No effects were found of internal and external focus of attention instructions and fall history on any of the outcome measures. We conclude that, compared to an internal focus of attention instruction, external focus to the walking surface does not lead to improved balance recovery responses to gait perturbations in the elderly.

Twenty-three elderly patients with normal renal function were studied during digitalisation for cardiac failure or atrial fibrillation. Mean serum digoxin concentrations were in the therapeutic range from the fourth day in seven patients given digoxin 0.25 mg daily, from the second day in seven patients given 0.5 mg followed by 0.25 mg daily, and from the first day in nine patients given 0.75 mg followed by 0.25 mg daily. Toxic effects were not encountered in any patient. Serial measurement of serum digoxin concentrations in six patients recovering from digitalis intoxication, all of whom had severe renal impairment, allowed calculation of serum half-times (62 to 189 hours), and elimination constants (9 to 27% per day). The apparent volumes of distribution of digoxin were around 300 litres, and the apparent body contents of the drugs around 20-25 mug/kg body weight. Differences between these figures and those determined by others for younger patients seem mainly to reflect the consequences of renal impairment. If reasonable assumptions are made for fractional absorption, volume of distribution, and elimination constant, serum digoxin levels during digitalisation can be predicted, and are found to agree well with those observed.

Full Text Available Elderly people often suffer from sarcopenia in their lower extremities, which gives rise to the increased susceptibility of fall. Comparing the mechanical properties of the knee extensor/flexors on elderly and young subjects is helpful in understanding the underlying mechanisms of the muscle aging process. However, although the stiffness of skeletal muscle has been proved to be positively correlated to its non-fatiguing contraction intensity by some existing methods, this conclusion has not been verified above 50% maximum voluntary contraction (MVC due to the limitation of their measurement range. In this study, a vibro-ultrasound system was set up to achieve a considerably larger measurement range on muscle stiffness estimation. Its feasibility was verified on self-made silicone phantoms by comparing with the mechanical indentation method. The system was then used to assess the stiffness of vastus intermedius (VI, one of the knee extensors, on 10 healthy elderly female subjects (56.7 ± 4.9 yr and 10 healthy young female subjects (27.6 ± 5.0 yr. The VI stiffness in its action direction was confirmed to be positively correlated to the % MVC level (R2 = 0.999 over the entire range of isometric contraction, i.e. from 0% MVC (relaxed state to 100% MVC. Furthermore, it was shown that there was no significant difference between the mean VI shear modulus of the elderly and young subjects in a relaxed state (p > 0.1. However, when performing step isometric contraction, the VI stiffness of young female subjects was found to be larger than that of elderly participants (p < 0.001, especially at the relatively higher contraction levels. The results expanded our knowledge on the mechanical property of the elderly's skeletal muscle and its relationship with intensity of active contraction. Furthermore, the vibro-ultrasound system has a potential to become a powerful tool for investigating the elderly's muscle diseases.

This study undertakes a survival analysis of elderly persons in China using Chinese Longitudinal Healthy Longevity Survey 2002–2008. Employing discrete-time multilevel models, we explored the effect of social support on the survival of elderly people in China. This study focuses on objective (living arrangements and received support) and subjective activities (perceived support) of social support, finding that the effect of different activities of social support on the survival of elderly people varies according to the availability of different support resources. Specifically, living with a spouse, financial independence, perceiving care support from any resource is associated with higher survival rates for elderly people. Separate analysis focusing on urban elderly and rural elderly revealed broadly similar results. There is a larger difference between those perceiving care support from family or social service and not perceiving care support in urban areas comparing to those in rural areas. Those who cannot pay medical expenses are the least likely to survive. The higher level of economic development in province has no significant effect on the survival of elderly people for the whole sample model and the elderly people in urban areas; however, there is a negative influence on the survival of the rural elderly people.

Full Text Available BackgroundPrevious reports have described that simple cognitive training using reading aloud and solving simple arithmetic calculations, so-called learning therapy, can improve executive functions and processing speed in the older adults. Nevertheless, it is not well-known whether learning therapy improve a wide range of cognitive functions or not. We investigated the beneficial effects of learning therapy on various cognitive functions in healthy older adults.MethodsWe used a single-blinded intervention with two groups (learning therapy group: LT and waiting list control group: WL. Sixty-four elderly were randomly assigned to LT or WL. In LT, participants performed reading Japanese aloud and solving simple calculations training tasks for 6 months. WL did not participate in the intervention. We measured several cognitive functions before and after 6 months intervention periods.ResultsCompared to WL, results revealed that LT improved inhibition performance in executive functions (Stroop: LT (Mean = 3.88 vs. WL (Mean = 1.22, adjusted p =.013 and reverse Stroop LT (Mean = 3.22 vs. WL (Mean = 1.59, adjusted p =.015, verbal episodic memory (logical memory: LT (Mean = 4.59 vs. WL (Mean = 2.47, adjusted p =.015, focus attention(D-CAT: LT (Mean = 2.09 vs. WL (Mean = -0.59, adjusted p =.010 and processing speed compared to the waiting list control group (digit symbol coding: LT (Mean = 5.00 vs. WL (Mean = 1.13, adjusted p =.015 and symbol search: LT (Mean = 3.47 vs. WL (Mean = 1.81, adjusted p =.014.DiscussionThis RCT can showed the benefit of learning therapy on inhibition of executive functions, verbal episodic memory, focus attention, and processing speed in healthy elderly people.

Brain amyloid β (Aβ) deposition and neurodegeneration have been documented in about 50-60% of cognitively healthy elderly individuals (aged 60 years or older). The long-term cognitive consequences of the presence of Alzheimer's disease pathology and neurodegeneration, and whether they have an independent or synergistic effect on cognition, are unclear. We aimed to characterise the long-term clinical and cognitive trajectories of healthy elderly individuals using a two-marker (Alzheimer's disease pathology and neurodegeneration) imaging construct. Between Nov 3, 2006, and Nov 25, 2014, 573 cognitively healthy individuals in Melbourne and Perth, Australia, (mean age 73·1 years [SD 6·2]; 58% women) were enrolled in the Australian Imaging, Biomarker and Lifestyle (AIBL) study. Alzheimer's disease pathology (A) was determined by measuring Aβ deposition by PET, and neurodegeneration (N) was established by measuring hippocampal volume using MRI. Individuals were categorised as A(-)N(-), A(+)N(-), A(+)N(+), or suspected non-Alzheimer's disease pathophysiology (A(-)N(+), SNAP). Clinical progression, hippocampal volume, standard neuropsychological tests, and domain-specific and global cognitive composite scores were assessed over 6 years of follow-up. Linear mixed effect models and a Cox proportional hazards model of survival were used to evaluate, compare, and contrast the clinical, cognitive, and volumetric trajectories of patients in the four AN categories. 50 (9%) healthy individuals were classified as A(+)N(+), 87 (15%) as A(+)N(-), 310 (54%) as A(-)N(-), and 126 (22%) as SNAP. APOE ε4 was more frequent in participants in the A(+)N(+) (27; 54%) and A(+)N(-) (42; 48%) groups than in the A(-)N(-) (66; 21%) and SNAP groups (23; 18%). The A(+)N(-) and A(+)N(+) groups had significantly faster cognitive decline than the A(-)N(-) group (0·08 SD per year for AIBL-Preclinical AD Cognitive Composite [PACC]; p<0·0001; and 0·25; p<0·0001; respectively).

Elderly people are becoming more prevalent in our country, which studies in this group are relevant. Moreover, the health impact of breakfast consumption is demonstrated in school groups. To determine whether breakfast consumption is associated with better quality of life in self-sufficient Chilean elderly. We interviewed 1,285 elderly (> 60 years) of both sexes. We applied two surveys (food and healthy lifestyles surveys), then an anthropometric evaluation was conducted. 5.6% of older adults does not consume breakfast. Those who consume breakfast had a better quality of life (p = 0.004), specifically in men breakfast intake is associated with lower body mass index (BMI) (p=0.002). Moreover, the results indicate that the proportion of elderly who smokes and does not take breakfast is higher, as well as, greater responsibility in health, nutrition, stress management are greater in those that take breakfast. Finally there was an association between breakfast consumption and better nutrition (p = 0.01) and self-realization (p = 0.005). Consumption of breakfast in older adults is associated with better quality of life. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

Mechanics of apparent horizons

International Nuclear Information System (INIS)

Collins, W.

1992-01-01

An equation for the variation in the surface area of an apparent horizon is derived which has the same form as the thermodynamic relation TdS=dQ. For a stationary vacuum black hole, the expression corresponding to a temperature equals the temperature of the event horizon. Also, if the black hole is perturbed infinitesimally by weak matter and gravitational fields, the area variation of the apparent horizon asymptotically approaches the Hartle-Hawking result for the event horizon. These results support the idea that a local version of black-hole thermodynamics in nonstationary systems can be constructed for apparent horizons

Self-estimation of performance implies the ability to understand one's own performance with relatively objective terms. Up to date, few studies have addressed this topic in mild cognitive impairment (MCI) patients. The aim of the present study was to compare objective measures of performance with subjective perception of specific performance on cognitive tests and investigate differences in assessment between MCI patients and healthy elderly. Thirty-five participants diagnosed with MCI (women = 16, men = 19, mean age = 65.09 years ±SD = 7.81, mean education = 12.83 years ±SD = 4.32) and 35 control subjects similar in terms of age and education (women = 20, men = 15, mean age = 62.46 years ± SD = 9.35, mean education = 14.26 ± SD = 2.84) were examined with an extended battery of neuropsychological tests. After every test they were asked to self-evaluate their performance by comparing it to what they considered as average for people of their age and educational level. This self-evaluation was reported on a scale ranging from -100 to +100. Significant differences were found in the self-assessment patterns of the two groups in memory measures of verbal and visual delayed recall, visuospatial perception, and tests of attention. MCI patients overestimated their performance on every cognitive domain while control participants underestimated their performance on measures of verbal memory. The present results indicate that accuracy of self-report is not uniform across groups and functional areas. The discrepancies in the MCI patients indicate unawareness of their memory deficits, which is contradictory to subjective memory complaints as being an important component for clinical diagnosis.

Full Text Available Yoga, a mind-body activity that requires attentional engagement, has been associated with positive changes in brain structure and function, especially in areas related to awareness, attention, executive functions and memory. Normal aging, on the other hand, has also been associated with structural and functional brain changes, but these generally involve decreased cognitive functions. The aim of this cross-sectional study was to compare brain cortical thickness (CT in elderly yoga practitioners and a group of age-matched healthy non-practitioners. We tested 21 older women who had practiced hatha yoga for at least 8 years and 21 women naive to yoga, meditation or any mind-body interventions who were matched to the first group in age, years of formal education and physical activity level. A T1-weighted MPRAGE sequence was acquired for each participant. Yoga practitioners showed significantly greater CT in a left prefrontal lobe cluster, which included portions of the lateral middle frontal gyrus, anterior superior frontal gyrus and dorsal superior frontal gyrus. We found greater CT in the left prefrontal cortex of healthy elderly women who trained yoga for a minimum of 8 years compared with women in the control group.

Positive affect contributes to the healthy life style, which, in turn, explains life satisfaction and psychological well-being among the elderly. Existent literature has reinforced that physical activity participation influences development of positive affect for the elderly. Because of the increased life constraints and physical problems, however, maintenance of positive affect might be challenging for elderly people. Data were drawn from a sample of the Survey of Health, Ageing and Retirement in Europe. A total sample of 3845 males and 3912 females aged between 65 and 103 years from 16 European countries was analyzed. Perception of life constraints, health problems, physical activity engagement and positive affect were measured by a structured questionnaire. Confirmatory factor analysis and a technique of structural equation modelling were employed using Amos 18 to examine the hypothesized relationships between study variables. Perceived life constraints and physical problems significantly affected the acquisition of positive affect among the elderly. Physical activity was found to have a significant path coefficient towards the measure of positive attitude and emotion. Physical activity was also a significant mediator between physical problems and positive affect. This study extended our understanding of how the perception of life constraints and health problems influence the elderly's daily experience. Study finding reinforced the goodness of physical activity participation to enhance positive affect among the elderly. We should administer sustainable and evidence-based physical activity including interventions and infrastructure to improve positive affect and psychological well-bing among the elderly. © The Author 2015.

spouses, and improved labor market opportunities for blacks and women. In recent years, defined contribution pension plans have become more prevalent than defined benefit plans, but the full effect of this change on pension income may not yet be apparent. After decades of decline, labor force participation rates of older men leveled out in the mid-1980s and then increased. For older women, the trend before the mid-1980s was flat, but since then rates have risen substantially. The increased use of part-time jobs or self-employment to ease the transition into retirement, the economic expansion of the 1990s, and the liberalization of the Social Security earnings test may all have contributed to those trends. Although the percentage of elderly people with earnings has increased only modestly in the past few years, the share of income from earnings has grown substantially--from 16 percent of income in 1984 to 23 percent in 2000. Finally, Supplemental Security Income (SSI) benefits are indexed for inflation but not for growth in real wages. As real incomes of the elderly rose, therefore, fewer elderly persons were eligible to receive SSI or, for those receiving SSI, were eligible for smaller benefits. The proportion of elderly persons receiving public assistance, primarily SSI, declined from 11 percent in 1976 to 5 percent in 2000.

Full Text Available Objective: Mental practice refers to "The symbolic rehearsal of a physical activity in the absence of any gross muscular movements." It has been shown in a remarkable number of studies that the use of mental practice like physical practice can produces significant improvements in motor skills. Thus this therapeutic technique can be used in elderly rehabilitation. The purpose of this study was to investigate the effects of mental practice on balance in the elderly. Materials & Methods: Thirty healthy old subject over the age of 60 years took part in this study. Subjects solicited from two senior-citizen centers in Tehran and randomly assigned to experimental and control groups. Balance of subjects was assessed in four stage include baseline, pre-treatment, post-treatment and follow-up. Subjects in experimental group performed mental practice of a motor and balance skill for 3 weeks and control group did not perform any practice in that period. Results: The results of this study indicate significant improvement in the motor skill that mentally performed and also in balance of subjects. Conclusion: Mental Practice that performed on the mental skill not only was mentaly effective but also meaningly cause the improvement of balance in elderly.

Assessment of the degree of air-flow obstruction is important for determining the treatment strategy in COPD patients. However, in some elderly COPD patients, measuring FVC is impossible because of cognitive dysfunction or severe dyspnea. In such patients a simple test of airways obstruction requiring only a short run of tidal breathing would be useful. We studied whether the spontaneous expiratory flow-volume (SEFV) curve pattern reflects the degree of air-flow obstruction in elderly COPD patients. In 34 elderly subjects (mean ± SD age 80 ± 7 y) with stable COPD (percent-of-predicted FEV(1) 39.0 ± 18.5%), and 12 age-matched healthy subjects, we measured FVC and recorded flow-volume curves during quiet breathing. We studied the SEFV curve patterns (concavity/convexity), spirometry results, breathing patterns, and demographics. The SEFV curve concavity/convexity prediction accuracy was examined by calculating the receiver operating characteristic curves, cutoff values, area under the curve, sensitivity, and specificity. Fourteen subjects with COPD had a concave SEFV curve. All the healthy subjects had convex SEFV curves. The COPD subjects who had concave SEFV curves often had very severe airway obstruction. The percent-of-predicted FEV(1)% (32.4%) was the most powerful SEFV curve concavity predictor (area under the curve 0.92, 95% CI 0.83-1.00), and had the highest sensitivity (0.93) and specificity (0.88). Concavity of the SEFV curve obtained during tidal breathing may be a useful test for determining the presence of very severe obstruction in elderly patients unable to perform a satisfactory FVC maneuver.

Full Text Available ABSTRACT: Qualitative study which aims was to describe the emotions in elderly life and to debate the relation between emotions and elderly health. The study was developed in a third age group at Sao Gonçalo city – RJ by participant observation and semi-structured interviews with ten elderly people. After the information analysis it was possible to identify the category "The Pendulum of Emotions" and two complementary subjects: rising and descending movement of emotions on living. The elderly evidenced that their emotions represents a continuous movement which reflects straightly to the feeling of being or not healthy and living well the third age is having autonomy of daily activities and freedom to participate of leisure and physical activities. Thus, the human being needs to valorize all the stages of his life, because the process of becoming old starts from the moment we were born and the quality of life is a daily conquest in this way.

The current study evaluated the effectiveness of a community-based elder abuse intervention program that assists suspected victims of elder abuse and self-neglect through a partnership with local law enforcement. This program, Eliciting Change in At-Risk Elders, involves building alliances with the elder and family members, connecting the elder to supportive services that reduce risk of further abuse, and utilizing motivational interviewing-type skills to help elders overcome ambivalence regarding making difficult life changes. Risk factors of elder abuse decreased over the course of the intervention and nearly three-quarters of participants made progress on their treatment goal, advancing at least one of Prochaska and DiClemente's (1983) stages of change (precontemplation, contemplation, preparation, action, and maintenance). Forty-three percent of elders moved into the stages of action and maintenance regarding their goal. The usefulness of eliciting change via longer-term relationships with vulnerable elders in entrenched elder abuse situations is discussed.

To identify the relationship among cognitive status, psychological conditions, anthropometric measurements and life-style in a sample of elderly Italian men and women. Three hundred and six volunteers for ZINCAGE Project recruited. The sample was made up of healthy older adults living in the Marche Region aged 65 and over. All elderly were given a complete medical, anthropometric assessment, and psycho-social evaluation. Overall, the participants perceived themselves to be in very good or good (22%) or fair (69%) health; only 9% reported a poor health status. The 46% of the sample fell within the normal body mass index (BMI) range, though 38% were overweight, 12% were obese, and only 4% were underweight. In both sexes, BMI significantly decreased with age (psedentary activities (r=0.188; psedentary (r=0.221; psedentary (r=0.258; p<0.001) leisure activities were positively associated with education level (p<0.05). It was found that lower scores of physical activity were associated to higher scores of Geriatric Depression Scale (r=-0.425; p<0.01), lower scores of Mini Mental State Examination (r=0.266; p<0.001) and higher score of Perceived Stress Scale (r=-0.131; p<0.05). Men and women lead different lifestyles and have a different psychological status, with advancing age consequently stressing the need for healthy lifestyle programmes particularly in the case of overweight and obese elderly people.

The complexities of elder abuse.

Elder abuse is a growing societal concern, affecting at least 1 in 10 older Americans. Researchers and practitioners alike consistently assert that a dramatic discrepancy exists between the prevalence rates of elder abuse and the number of elder abuse cases reported. As a field of study, recognition and understanding of elder abuse is still emerging. Comparing findings of a small, but growing, body of literature on perceived and substantiated cases of elder abuse is challenging because there is no uniform term or agreed-upon definition used among state governments, researchers, health care and service providers, and advocates. This article summarizes current understanding of elder abuse, including what constitutes elder abuse, risk factors for elder abuse, perpetrators of elder abuse, and outcomes of elder abuse. Issues associated with the detection of elder abuse and intervention strategies for victims of abuse are addressed. In the final section, potential roles and contributions of psychologists for advancing elder abuse research, professional practice, and policy development are highlighted.

Research has shown that the Nintendo Wii Balance Board (WBB) can reliably detect the quantitative kinematics of the center of pressure in stance. Previous studies used relatively coarse manipulations (1- vs. 2-leg stance, and eyes open vs. closed). We sought to determine whether the WBB could reliably detect postural changes associated with subtle variations in visual tasks. Healthy elderly adults stood on a WBB while performing one of two visual tasks. In the Inspection task, they maintained their gaze within the boundaries of a featureless target. In the Search task, they counted the occurrence of designated target letters within a block of text. Consistent with previous studies using traditional force plates, the positional variability of the center of pressure was reduced during performance of the Search task, relative to movement during performance of the Inspection task. Using detrended fluctuation analysis, a measure of movement dynamics, we found that COP trajectories were more predictable during performance of the Search task than during performance of the Inspection task. The results indicate that the WBB is sensitive to subtle variations in both the magnitude and dynamics of body sway that are related to variations in visual tasks engaged in during stance. The WBB is an inexpensive, reliable technology that can be used to evaluate subtle characteristics of body sway in large or widely dispersed samples. Copyright © 2012 Elsevier B.V.

To compare the nutritional factors and oral status of elders living alone and elders living with their families in Korea. Numerous studies have found that the presence of fewer remaining teeth is associated with decreased nutrient intake; however, there is no study comparing the nutritional status and oral status of elders living alone with that of elders living with family based on a nationally representative sample. A sample of 2904 individuals who participated in the sixth Korean National Health and Nutrition Examination Survey was reviewed (65-84 years of age). Living status was defined according to the participants' self-reported questionnaire, and a nutrient intake questionnaire was designed as an open questionnaire and used during the face-to-face interviews. The number of existing teeth was used to determine oral status. A complex-sample general linear analysis and multivariate logistic regression analysis were used to evaluate the association between the number of teeth and nutrient intake among elders living with family and elders living alone after adjusting for confounders. Elders living alone were significantly older and tended to have the following characteristics: women, lower household income, lower educational level, poor perceived health status, non-smokers, non-drinkers and lack of physical activity. Elders living alone had a poorer perceived oral health status, had not received an oral examination in the past year, had chewing problems and had fewer existing teeth (P oral health and nutrient intake status. Participants who had many existing teeth had higher nutrient intake than the participants who had fewer existing teeth. For healthy lives at old age, family support or additional social support for elders living alone should be considered. © 2018 John Wiley & Sons A/S and The Gerodontology Association.

The net interconversion of inactive cortisone to active cortisol by 11beta-hydroxysteroid dehydrogenase type 1 (11betaHSD1) may determine hepatic and adipose tissue exposure to glucocorticoid action. Cortisol metabolism exhibits a sexual dimorphism with an apparently lower activity of 11betaHSD1 in females that, in an animal model, has been attributed to the effects of oestrogen. The aim of this study is to determine whether the sexual dimorphism of cortisol metabolism persists between post-menopausal, oestrogen-deficient women and elderly men. Fifteen healthy men, aged 60.8-82.0 years, and 7 healthy women, aged 62.4-87.5 years, were studied. None of the subjects was receiving steroid medication at the time of the study. All the women were post-menopausal and none was receiving sex steroid replacement therapy. 24-h urine collections were taken from each patient and assayed for steroid metabolites by gas chromatography. Body composition was determined by dual energy X-ray absorptiometry. Blood was drawn, after an overnight fast, for the determination of serum IGF-I and IGFBP1 levels. The ratio of 11-hydroxy cortisol metabolites to 11-oxo cortisol metabolites (Fm/Em) was significantly higher in men than in women, 0.80 (0.55-1.86) vs. 0.67 (0.46-0.98) (P cortisol and cortisone metabolite (Fm/Em) and total fat mass approached significance, r = - 0.39 (P = 0.07). These relationships were not apparent in the women when considered alone. Among the men there were negative relationships between Fm/Em and total fat mass, r = - 0.48, and Fm/Em and trunk fat mass, r = - 0.48 which approached significance (both P = 0.07). Serum IGFBP-1 levels were not significantly different between the two sexes. There was a significant correlation between IGFBP-1 and Fm/Em in the men, r = 0. 84 (P sexual dimorphism in cortisol metabolism is not dependent on oestrogen, although the possibility that oestrogen exerts a permanent modifying effect on 11beta-HSD1 gene expression during the pre

Population ageing is a worldwide phenomenon experienced by developed and developing countries. It occurs when the median age of a country rises and shifts the distribution of that country's population towards older ages. Malaysia is experiencing a dramatic increase in the number of elderly people. Recent medical advances and improvements in hygiene and food supply have led to the people of Malaysia having a longer life expectancy. This paper comprehensively reviews articles and journals to discover the concepts, definitions and issues regarding the ageing population globally and in Malaysia, particularly looking at how elderly people can age in place. The concern over ageing is not just about the size of the old age population but, more importantly, about their health, welfare, care and living arrangements as well as the implications for infrastructure, housing, income and economic growth. The built environment plays a role in defining the conditions for people to live healthy lives, and older people require high-quality built environments that suit their needs across the whole life course - a building stock and infrastructure that supports independent living and enhances quality of life for the ageing population. Lifetime houses which fulfil the desires and vital requirement of most households whilst considering the changing essentials of households with elderly and aged people require careful consideration. This paper will review the key areas of housing for elderly people to support the concept of ageing in place as an independent living lifestyle.

Methods: Between 2000 and 2002, 83 elderly participants of GAMIA were assessed by the World Health Organization Quality of Life scale (WHOQOL-bref at the beginning and the end of the program. Functionality was assessed by Katz and Lawton scales and sociodemographic data were obtained from medical charts. Results: Females predominated (79.5% and overall mean age was 69.30 years. Data analysis showed a reduction in the physical domain of WHOQOL-bref (p = 0.014 and increased psychological health and environment domains (p = 0.029 and p = 0.007, respectively, detecting a trend of increase in social relationships and in general domains (p = 0.062 and p = 0.052, respectively. Conclusions: The clinical evaluation of the elderly detected previously unknown diseases and determination of the use of new drugs, which might have been the predominant factor for the deterioration of their perception in the physical domain. Improvement in psychological health and the environment can be related to psychological and social support that the elderly received from peers and professionals and the benefits of group activities, as well as the upward trend observed in social relationships and general domains. Participation in a program to promote healthy aging was effective in improving the quality of life of the elderly.

To compare the risk factors on the functional dependence between the oldest-old and elderly veterans. A cross-sectional survey was conducted among veterans ( ≥ 60 years of age) lived in 44 veterans' communities in Beijing. The socio-demographic information and history of non-communicable chronic diseases were collected via face-to-face interviews, and the functional status was assessed by the 20-item version of the Activities of Daily Living Scale. The risk factors associated with increased hazard of the functional dependence in the oldest-old ( ≥ 80 years old) were cognitive impairment, extrapyramidal diseases, cerebral infarction, transient ischemic attack, sleep disorders, hypnotics, osteoarthrosis, hypertension and fall with the odds ratio (OR) of 1.241-2.962 (all P fall, cardiovascular diseases, osteoarthrosis and hearing loss were the risk factors for that in the elderly subjects (aged 60-79 years). The OR was 1.232-5.790 (all P risk of functional dependence in both the oldest-old and elderly people. Neuropsychiatric disorders are the leading causes contributed to the functional dependence among oldest-old and elderly population. Neurodegenerative diseases in the oldest-old, stroke and depression in elderly people should be the priorities in ameliorating disability. Healthy lifestyle and avocational activities could improve the functional status of the oldest-old and elderly population.

BACKGROUND: Based on circulating C-reactive protein (CRP) levels, some individuals develop slightly increased inflammation as they age. In elderly inflamed rats, the muscle response to protein feeding is impaired, whereas it can be maintained by treatment with non-steroidal anti-inflammatory drugs...... (NSAIDs). It is unknown whether this applies to elderly humans with increased inflammation. Thus, the muscle response to whey protein bolus ingestion with and without acute resistance exercise was compared between healthy elderly individuals and elderly individuals with slightly increased inflammation......protein synthetic response was measured as the fractional synthetic rate (FSR) and p70S6K phosphorylation-to-total protein ratio. RESULTS: The basal myofibrillar FSR and the myofibrillar FSR responses to whey protein bolus ingestion with and without acute resistance exercise were...

Abstract: Background: A positive correlation between elderly dependency ratios and elderly suicide rates has been observed using one-year cross-sectional data on elderly suicide rates. Methods: A cross-national study designed to replicate this positive correlation between elderly dependency ratios and elderly suicide rates was undertaken by: (i) using one-year average of five years data on suicide rates; and (ii) using more recent data on both elderly suicide rates and elderly dependency ratios. Data on elderly suicide rates, and the total number of elderly and young people was ascertained from the World Health Organization website. Results: The main findings were of significant positive correlations between elderly dependency ratios and suicide rates in both sexes in both the elderly age-bands (65-74 years and 75+ years). Conclusions: The replication of the positive correlations between elderly dependency ratios and elderly suicide rates by using one-year average of five years data on suicide rates suggests that this relationship is robust and accurate.

2016-11-01

Full Text Available Introduction: Elder neglect remains as unreported case that involved old women in Ampenan West Nusa Tenggara. Despite the paucity of evidence to report the significance, an earlier pilot study showed that elders who lived with their family in Ampenan were found dirty, skin dry, and malnourished. The purpose of this study was to explore the correlating factors to the unreported cases of neglect among these elders. Method: This study was a cross sectional conducted using analytic descriptive approach. Thirty-four extended families lived with female elders in the working area of Puskesmas Ampenan were purposively involved as participants to this study. Family’s awareness of abuse was collected using a questionnaire developed based on Elder Abuse Instrument component checklist and the suspicion to neglect among the elders were collected using the 13-item checklist from Elder Abuse Instrument. The data were then analyzed using Spearman’s rho (α ≤ 0,05. Result:  The results show that family’s lack of knowledge has a strong correlation with elder neglect (p= 0,000 with r= 0,643. Discussion: The analysis to this finding suggests that not only were the families lack of knowledge, but they were also being burden by the poor economic situation that trigger the unnecessary neglect to their female elders. These results abridge the paucity of evidence to explain the correlating factors with the incidence of elder abuse in eastern Indonesia. Further research is necessary to explain the size and the impact of neglect toward the elders. It is suggested that local department of health, Puskesmas and health professionals to educate the community as the first step to improve the elders’ quality of life and promote healthy ageing.

Age differences in implicit memory: more apparent than real.

Russo, R; Parkin, A J

1993-01-01

Elderly subjects and a group of young subjects identified fragmented picture sequences under conditions of focused attention. Two other groups of young subjects carried out this task under divided-attention conditions. Implicit memory, as measured by item-specific savings, was found in all groups, but this effect was smaller in the elderly group. The young subjects, but not elderly subjects, performed better on new items. The divided-attention conditions equated recall and recognition by the young and the elderly, but only the young subjects showed greater savings for recalled items. The elderly subjects' reduced implicit memory therefore stemmed from their inability to facilitate implicit memory with explicit memory. A second experiment, involving only young subjects tested after delay, produced findings similar to those for the young divided-attention subjects. Implicit memory, as measured by savings in picture completion, does not show an age-related change when the role of explicit memory is considered. Age does, however, reduce skill learning.

Can an active aging index (AAI) provide insight into reducing elder abuse? A case study in Rajshahi District, Bangladesh.

2014-01-01

We use data from respondents aged 60 years and above, collected during April 2009 in the Rajshahi district of Bangladesh, to examine whether high activeness, as captured by an AAI or in sub-domains, can help reduce the risk of elder abuse. The findings suggest that more than half of rural elderly and 14 percent of urban elderly were at some point abused. High activeness in health and security dimensions lowers the risk of being abused while those who are low active in community participation have the lowest risk of being abused in both rural and urban areas. Being literate (elderly with primary/secondary education) is revealed to be a significant factor that lowers the risk of abuse in both rural and urban areas. These results imply a need for educational programs that bolster positive and proper community interaction, in turn promoting a secure later life for elders, and reducing burden for families and society. High activeness in health and security dimensions should also be promoted to keep the elderly healthy and protect from abusive behavior. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Scientific evidence indicates that adherence to the Mediterranean diet protects against the deterioration of cognitive status and depressive symptoms during aging. However, few studies have been conducted in elderly non-institutionalized subjects. This study evaluated the relation between the adherence to the Mediterranean dietary pattern and cognitive status and depressive symptoms in an elderly population over 75 years. A cross-sectional study was conducted in a Mediterranean city (Garrucha, Spain) in 79 elderly people over 75 (36 men and 41 women). Adherence to the Mediterranean dietary pattern was determined using the Mediterranean Diet Adherence Screener (MEDAS). Cognitive function was determined by the Mini Mental State Examination (MMSE), and depressive symptoms were assessed by the Geriatric Depression Scale (GDS). Most of population showed a very high adherence to the Mediterranean diet pattern and optimal cognitive and affective status. They consumed olive oil as their main source of fat, high levels of fish and fruit, low levels of foods with added sugars, and a low consumption of red meat. A significant relation between the MEDAS and MMSE scores was found. However, no relationship was observed between the MEDAS and GDS. The Mediterranean diet pattern was positively related with the cognitive function, although the infl uence of a healthy dietary pattern on the symptomatology of depression was unclear. However, an effective strategy against cognitive function and depression would be to improve physical activity rates, establish lifelong healthy eating habits, and consume a nutritionally-rich diet in order to enhance quality of life of the elderly.

Aging-related physical changes do not necessarily lead to a decline in sexual functioning: good physical and mental health, a positive attitude toward sex in later life, and access to a healthy partner are associated with continued sexual activity, and regular sexual expression is associated with good physical and mental health. However, it is usually assumed that older adults do not have sexual desires, and elderly people often find it difficult to discuss this topic with their doctor. There are many potential barriers concerning sexuality in older age: the lack of a healthy sexual partner, depression, the monotony of a repetitive sexual relationship, a spouse's physical unattractiveness, hormone variability, and illness and/or iatrogenic factors. Adaptive coping strategies can considerably mitigate the impact of such factors, however, and one way of contributing to breaking down barriers and taboos is undoubtedly to ensure that physicians are willing to discuss their patients' sexual history. The aim of this review was to explore the barriers and taboos to sexual expression in seniors, to propose strategies to foster this aspect of their lives, and to help physicians investigate the sexual history of their elderly patients.

[Purpose] To examine the ability of young and elderly individuals to control the timing and force of periodic sequential foot tapping. [Subjects and Methods] Participants were 10 young (age, 22.1 ± 4.3 years) and 10 elderly individuals (74.8 ± 6.7 years) who were healthy and active. The foot tapping task consisted of practice (stimulus-synchronized tapping with visual feedback) and recall trials (self-paced tapping without visual feedback), periodically performed in this order, at 500-, 1,000-, and 2,000-ms target interstimulus-onset intervals, with a target force of 20% maximum voluntary contraction of the ankle plantar-flexor muscle. [Results] The coefficients of variation of force and intertap interval, used for quantifying the steadiness of the trials, were significantly greater in the elderly than in the young individuals. At the 500-ms interstimulus-onset interval, age-related effects were observed on the normalized mean absolute error of force, which was used to quantify the accuracy of the trials. The coefficients of variation of intertap interval for elderly individuals were significantly greater in the practice than in the recall trials at the 500- and 1,000-ms interstimulus-onset intervals. [Conclusion] The elderly individuals exhibited greater force and timing variability than the young individuals and showed impaired visuomotor processing during foot tapping sequences.

To evaluate the inter-device agreement among the Goldmann applanation tonometer (GAT), iCare and Icare PRO rebound tonometers, non-contact tonometer (NCT), and Tonopen XL tonometer. Sixty healthy elderly subjects were enrolled. The intraocular pressure (IOP) in each subject's right eye was measured thrice using each of the five tonometers. Intra-device agreement was evaluated by calculating intraclass correlation coefficients (ICCs). Inter-device agreement was evaluated by ICC and Bland-Altman analyses. ICCs for intra-device agreement for each tonometer were >0.8. IOP as measured by iCare (mean ± SD, 11.6 ± 2.5 mmHg) was significantly lower (p tonometers (all ICCs tonometers ranged from 14.94 to 16.47 mmHg. Among the other tonometers, however, the widths of 95% limits of agreement ranged from 7.91 to 9.24 mmHg. There was good inter-device agreement among GAT, rebound tonometers, and NCT. Tonopen XL shows the worst agreement with the other tonometers; therefore, we should pay attention to its' respective IOP. Japan Clinical Trials Register; number: UMIN000011544.

Diffusion-tensor imaging and single voxel diffusion-weighted magnetic resonance spectroscopy were used at 7T to explore in vivo age-related microstructural changes in the corpus callosum. Sixteen healthy elderly (age range 60-71 years) and 13 healthy younger controls (age range 23-32 years) were included in the study. In healthy elderly, we found lower water fractional anisotropy and higher water mean diffusivity and radial diffusivity in the corpus callosum, indicating the onset of demyelination processes with healthy aging. These changes were not associated with a concomitant significant difference in the cytosolic diffusivity of the intra-axonal metabolite N-acetylaspartate (p = 0.12), the latter representing a pure measure of intra-axonal integrity. It was concluded that the possible intra-axonal changes associated with normal aging processes are below the detection level of diffusion-weighted magnetic resonance spectroscopy in our experiment (e.g., smaller than 10%) in the age range investigated. Lower axial diffusivity of total creatine was observed in the elderly group (p = 0.058), possibly linked to a dysfunction in the energy metabolism associated with a deficit in myelin synthesis.

To examine factors that may have impact on the Mini-Mental State Examination (MMSE) screening validity, which could lead to further establishing the general model of the MMSE score in Chinese health elderly and to improve the screening accuracy of the existing MMSE reference. Based on the data of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), the MMSE scores of 19,117 normal elderly and 137 dementia patients who met the inclusion criteria were used for the analysis. The area under the curve (AUC) and validity indexes were used to compare the screening accuracy of various criteria. Multiple linear regression was used to identify factors that had impact on the MMSE score for both the normal and dementia elderly. Descriptive analysis was performed for differences in the MMSE scores by age trends and gender between the normal and dementia elderly. The AUC of MMSE was ≥0.75(Pvalidity of MMSE in CLHLS is not affected by educational level. The analysis of factors that may impact on the MMSE screening validity are gender, age, vision and residence which with validity identification. These four factors can be used as assist tool of MMSE in the screening of dementia to improve the screening accuracy.

Total blood homocysteine (Hcys) and folate levels have been investigated in association with cognitive dysfunction in healthy but not in multimorbid elderly patients. We hypothesized that total serum Hcys is an adequate marker to identify multimorbid elderly patients with cognitive dysfunction assessed by the Short Cognitive Performance Test (SKT) and Mini-Mental State Examination (MMSE). Cross-sectional study. The study center was an acute geriatric hospital. A total of 189 multimorbid elderly patients were recruited. Cognitive dysfunction was determined according to the SKT and MMSE. Biochemical parameters (Hcys, folate, vitamin B12, hemoglobin), nutritional status (BMI, Mini Nutritional Assessment, nutritional intake), and activities of daily living were assessed. According to the SKT, 25.4% of patients showed no cerebral cognitive dysfunction, 21.2% had suspected incipient cognitive dysfunction, 12.7% showed mild cognitive dysfunction, 9.0% had moderate cognitive dysfunction, and 31.7% of patients were demented. The median plasma Hcys value was elevated by approximately 20% in multimorbid elderly patients, independent of cognitive dysfunction. Serum folate and vitamin B12 concentrations were within normal ranges. We did not find significant differences in nutritional status, activities of daily living, numbers of diseases or medications, or selected biochemical parameters between the SKT groups. Elevated serum Hcys levels with normal plasma folate and vitamin B12 concentrations were observed in multimorbid elderly patients. The plasma Hcys level did not appear to be an important biological risk factor for cognitive dysfunction in multimorbid geriatric patients.

Family Spirituality and Family Health Among Korean-American Elderly Couples.

Kim, Suk-Sun; Kim-Godwin, Yeoun Soo; Koenig, Harold G

2016-04-01

Spirituality has been regarded as an individual and private matter; consequently, research on spirituality as a family phenomenon has been largely neglected. In addition, most published research has been focused on Western cultures. The purpose of this study was to explore the experience of family spirituality and how it influences health among Korean-American elderly couples who are the first generation to reside in the Southeastern USA. A thematic and interpretive data analysis method was used. Thirteen elderly couples (N = 26) participated in in-depth individual interviews in Korean with the primary author. Interviews were audio-taped, transcribed, and then translated by two bilingual researchers with a background in Korean and American culture. Three main themes of family spirituality were identified: (1) family togetherness, (2) family interdependence, and (3) family coping. Also, participants reported that family spirituality strengthened family health by fostering family commitment, improving emotional well-being, developing new healthy behaviors, and providing healing experiences. This finding implies that healthcare providers need to assess family spiritual issues of elderly couples to maximize their strengths for coping with health problems. As our society becomes more culturally diverse, healthcare providers should seek to understand family spirituality from different cultural perspectives to develop a more holistic approach to care.

A positive correlation between elderly dependency ratios and elderly suicide rates has been observed using one-year cross-sectional data on elderly suicide rates. A cross-national study designed to replicate this positive correlation between elderly dependency ratios and elderly suicide rates was undertaken by: (i) using one-year average of five years data on suicide rates; and (ii) using more recent data on both elderly suicide rates and elderly dependency ratios. Data on elderly suicide rates, and the total number of elderly and young people was ascertained from the World Health Organization website. The main findings were of significant positive correlations between elderly dependency ratios and suicide rates in both sexes in both the elderly age-bands (65-74 years and 75+ years). The replication of the positive correlations between elderly dependency ratios and elderly suicide rates by using one-year average of five years data on suicide rates suggests that this relationship is robust and accurate. ‎

An exploration of antecedents of positive affect among the elderly: a cross-sectional study

2016-01-01

Abstract Background: Positive affect contributes to the healthy life style, which, in turn, explains life satisfaction and psychological well-being among the elderly. Existent literature has reinforced that physical activity participation influences development of positive affect for the elderly. Because of the increased life constraints and physical problems, however, maintenance of positive affect might be challenging for elderly people. Methods : Data were drawn from a sample of the Survey of Health, Ageing and Retirement in Europe. A total sample of 3845 males and 3912 females aged between 65 and 103 years from 16 European countries was analyzed. Perception of life constraints, health problems, physical activity engagement and positive affect were measured by a structured questionnaire. Confirmatory factor analysis and a technique of structural equation modelling were employed using Amos 18 to examine the hypothesized relationships between study variables. Results: Perceived life constraints and physical problems significantly affected the acquisition of positive affect among the elderly. Physical activity was found to have a significant path coefficient towards the measure of positive attitude and emotion. Physical activity was also a significant mediator between physical problems and positive affect. Conclusions: This study extended our understanding of how the perception of life constraints and health problems influence the elderly’s daily experience. Study finding reinforced the goodness of physical activity participation to enhance positive affect among the elderly. We should administer sustainable and evidence-based physical activity including interventions and infrastructure to improve positive affect and psychological well-bing among the elderly.

Full Text Available The impact of the world-wide ageing population has commenced with respect to society in developed countries. Several researchers focused on exploring new methods to improve the quality of life of elderly individuals by allowing them to remain independent and healthy to the maximum possible extent. For example, new walking aids are designed to allow elderly individuals to remain mobile in a safe manner because the importance of walking is well-known. The aim of the present study involves designing a humanoid robot guide as a walking trainer for elderly individuals. It is hypothesized that the same service robot provides an assistive and social contribution with respect to interaction between elderly users by motivating them to walk more and simultaneously provides assistance, such as physical assistance and gait monitoring, while walking. This study includes a detailed statement of the research problem as well as a literature review of existing studies related to walking companion robots. A user-centred design approach is adopted to report the results of the current first feasibility study by using a commercially available humanoid robot known as Pepper developed by Softbank-Aldebaran. A quantitative questionnaire was used to investigate all elements that assess intrinsic motivation in users while performing a given activity. Conversely, basic gait data were acquired through a video analysis to test the capability of the robot to modify the gait of human users. The results in terms of the feedback received from elderly subjects and the literature review improve the design of the walking trainer for elderly individuals.

What is the mean Berg Balance Scale score of healthy elderly people living in the community and how does it vary with age? How much variability in Berg Balance Scale scores is present in groups of healthy elderly people and how does this vary with age? Systematic review with meta-analysis. Any group of healthy community-dwelling people with a mean age of 70 years or greater that has undergone assessment using the Berg Balance Scale. Mean and standard deviations of Berg Balance Scale scores within cohorts of elderly people of known mean age. The search yielded 17 relevant studies contributing data from a total of 1363 participants. The mean Berg Balance Scale scores ranged from 37 to 55 out of a possible maximum score of 56. The standard deviation of Berg Balance Scale scores varied from 1.0 to 9.2. Although participants aged around 70 years had very close to normal Berg Balance Scale scores, there was a significant decline in balance with age at a rate of 0.7 points on the 56-point Berg Balance Scale per year. There was also a strong association between increasing age and increasing variability in balance (R(2) = 0.56, p balance deficits, as measured by the Berg Balance Scale, although balance scores deteriorate and become more variable with age.

Battison, Andrea L; Després, Béatrice M; Greenwood, Spencer J

2008-10-01

An intermoult male American lobster, Homarus americanus, with severe intestinal lesions was encountered while collecting samples of aerobic intestinal bacteria from lobsters held in an artificial sea-water recirculation aquarium system. Grossly, the intestine was firm, thickened, and white. Histologic examination revealed a severe, diffuse, ulcerative enteritis which spared the chitin-lined colon, somewhat similar to hemocytic enteritis of shrimp. The bacterial isolates from this lobster were compared to 11 other lobsters lacking gross intestinal lesions. Two organisms, one identified as Vibrio sp. and another most similar to an uncultured proteobacterium (98.9%), clustering with Rhanella and Serratia species using 16S rDNA PCR, were isolated from the intestines of the 11, grossly normal, lobsters and the affected lobster. An additional two intestinal isolates were cultured only from the lobster with ulcerative enteritis. One, a Flavobacterium, similar to Lutibacter litoralis (99.3%), possibly represented a previously described commensal of the distal intestine. The second, a Vibrio sp., was unique to the affected animal. While the etiology of the ulcerative enteritis remains undetermined, this report represents the first description of gross and histologic findings in H. americanus of a condition which has morphologic similarities to hemocytic enteritis of shrimp. An additional observation was a decrease in the number of intestinal isolates recovered from the 11 apparently healthy lobsters compared to that previously reported for recently harvested lobster. More comprehensive studies of the relationship between the health of lobsters, gut microbial flora and the husbandry and environment maintained within holding units are warranted.

Full Text Available Objectives. To analyze the effect of aging on sentence auditory comprehension and to study the relationship between this language skill and cognitive functions (attention, working memory, and executive functions. Methods. A total of 90 healthy subjects were divided into three groups: adults (50–59 years, young-old (60–69 years, and old-old (70–80 years. Subjects were assessed using the Revised Token Test. The measures used for performance analysis were number of correct answers (accuracy and execution time of commands on the different subtests. Results. Regarding accuracy, groups showed similar performance on the first blocks, but the young-old and old-old performed worse than adults on blocks 9 and 10. With respect to execution time, groups differed from block 2 (i.e., the groups differed for all blocks, except for block 1, with the worst performance observed in the old-old group, followed by that of the young-old group. Therefore, the elderly required more time to attain performance similar to that of adults, showing that time measurements are more sensitive for detecting the effects of age. Sentence comprehension ability is correlated with cognitive test performance, especially for global cognition and working memory tests. Conclusions. Healthy aging is characterized by the ability to compensate for difficulties in linguistic processing, which allows the elderly to maintain functional communication.

Older adults are more vulnerable to health risks than younger people and may get exposed to various dangers, including elder abuse. This study aimed to design and implement an empowerment educational intervention to prevent elder abuse. This parallel randomized controlled trial was conducted in 2014-2016 for 18 months on 464 older adults aged above 60 years who visited health houses of 22 municipalities in Tehran. Data were collected using standard questionnaires, including the Elder Abuse-Knowledge Questionnaire, Health-Promoting Behavior Questionnaire, Health-Promoting Lifestyle Profile II, Barriers to Healthy Lifestyle, Perceived Social Support, Perceived Self-Efficacy, Loneliness Scale, Geriatric Depression Scale, Multidimensional Health Locus of Control Scale, and the SCARED (stress, coping, argument, resources, events, and dependence) tool. The intervention was done in twenty 45- to 60-minute training sessions over 6 months. Data analysis were performed using χ 2 tests, multiple linear and logistic regression, and structural equation modeling (SEM). The frequency of knowledge of elder abuse, self-efficacy, social support and health promoting lifestyle before the intervention was similar in the two groups. However, the frequency of high knowledge of elder abuse (94.8% in the intervention group and 46.6% in the control group), high self-efficacy (82.8% and 7.8%, respectively), high social support (97.0% and 10.3%, respectively) and high health promoting lifestyle (97.0% and 10.3%, respectively) was significantly higher ( P elder abuse risk (28.0% and 49.6%, respectively) was significantly less in the intervention group after the intervention. SEM standardized beta (Sβ) showed that the intervention had the highest impact on increase social support (Sβ=0.80, β=48.64, SE=1.70, P elder abuse risk was indirect and significant (Sβ=-0.406, β=-0.340, SE=0.03, P elder abuse.

Menezes, Tânia Maria de Oliva; Lopes, Regina Lúcia Mendonça

2014-08-01

This is a study using the Heideggerian theoretical-phenomenological approach, which sought to understand the significances of the life experience for the long-lived elderly person in the process of death/dying and mourning. It was conducted in 2009 with 16 long-lived senior citizens of both genders who were aged between 80 and 90, members of a community center for the elderly located in a suburban neighborhood of the city of Salvador in the state of Bahia, Brazil. The results showed that the long-lived elderly person experiences the mourning status process when relatives and friends become ill and die. Furthermore, they gave ambiguous reports with respect to the fear of death. With the attributed significances, it was possible to arrive at the unit of significance, namely the authenticity and lack of authenticity of the individual regarding imminent death. The conclusion reached is that long-lived elderly individuals faced with the process of death/dying and mourning is apparent or concealed in accordance with the moment they are experiencing and the opportunities that present themselves, in other words, it is greatly influenced by their past.

Full Text Available Although many obese individuals are normoglycemic and asymptomatic of cardiometabolic complications, this apparent healthy state may be a misnomer. Since heart failure is a major cause of mortality in obesity, we investigated the effects of heme-oxygenase (HO on heart failure and cardiometabolic complications in obese normoglycemic Zucker-fatty rats (ZFs. Treatment with the HO-inducer, hemin, reduced markers of heart failure, such as osteopontin and osteoprotegerin, abated left-ventricular (LV hypertrophy/fibrosis, extracellular matrix/profibrotic proteins including collagen IV, fibronectin, TGF-β1, and reduced cardiac lesions. Furthermore, hemin suppressed inflammation by abating macrophage chemoattractant protein-1, macrophage-inflammatory protein-1 alpha, TNF-α, IL-6, and IL-1β but enhanced adiponectin, atrial-natriuretic peptide (ANP, HO activity, insulin sensitivity, and glucose metabolism. Correspondingly, hemin improved several hemodynamic/echocardiographic parameters including LV-diastolic wall thickness, LV-systolic wall thickness, mean-arterial pressure, arterial-systolic pressure, arterial-diastolic pressure, LV-developed pressure, +dP/dt, and cardiac output. Contrarily, the HO-inhibitor, stannous mesoporphyrin nullified the hemin effect, exacerbating inflammatory/oxidative insults and aggravated insulin resistance (HOMA-index. We conclude that perturbations in insulin signaling and cardiac function may be forerunners to overt hyperglycemia and heart failure in obesity. Importantly, hemin improves cardiac function by suppressing markers of heart failure, LV hypertrophy, cardiac lesions, extracellular matrix/profibrotic proteins, and inflammatory/oxidative mediators, while concomitantly enhancing the HO-adiponectin-ANP axis.

FreeSurfer is a tool to quantify cortical and subcortical brain anatomy automatically and noninvasively. Previous studies have reported reliability and statistical power analyses in relatively small samples or only selected one aspect of brain anatomy. Here, we investigated reliability and statistical power of cortical thickness, surface area, volume, and the volume of subcortical structures in a large sample (N=189) of healthy elderly subjects (64+ years). Reliability (intraclass correlation coefficient) of cortical and subcortical parameters is generally high (cortical: ICCs>0.87, subcortical: ICCs>0.95). Surface-based smoothing increases reliability of cortical thickness maps, while it decreases reliability of cortical surface area and volume. Nevertheless, statistical power of all measures benefits from smoothing. When aiming to detect a 10% difference between groups, the number of subjects required to test effects with sufficient power over the entire cortex varies between cortical measures (cortical thickness: N=39, surface area: N=21, volume: N=81; 10mm smoothing, power=0.8, α=0.05). For subcortical regions this number is between 16 and 76 subjects, depending on the region. We also demonstrate the advantage of within-subject designs over between-subject designs. Furthermore, we publicly provide a tool that allows researchers to perform a priori power analysis and sensitivity analysis to help evaluate previously published studies and to design future studies with sufficient statistical power.

Participating in a community with other retired individuals to increase life quality can be possible for the older persons. Cultural and ethnical background is important for their social identity. To identify what the informants think is important in their surroundings in order to extend their healthy life period. A structured questionnaire developed by the OCIN network. Nineteen elderly women aged 75 years or more were interviewed. This regional survey is a pilot study in Norway. The data were collected during 2 periods, in 2009 and 2010. The data are analyzed using a result scheme prepared by the network OCIN. Our findings show that this is a group of elderly women that are concerned with promoting their own health. The participants wish to take care of themselves, so they do not become a burden for society and the local authorities. The findings of this study suggest that participation in the local context is important for promoting health and well-being among elderly in all ethnicities. For the Sami elderly, this is particularly important because meeting equal-minded people helps them maintain their Sami identity. In the Sami culture and among the Sami elderly, it is important to be "strong" and "healthy". Due to these norms, the elderly Sami women try to live with their illnesses and are less eager to go to the doctor when they are seriously ill.

The 'Healthy Habits Program' is a 6-month community-based program, which offers exercise facilities, training and weekly health education group to underserved elderly Chinese Americans with chronic medical diseases in their native languages. This pilot study evaluates the acceptability and the health effects of the 'Healthy Habits Program'. Ninety-nine subjects participated in the 'Healthy Habits Program' in 2011. Before and after the program, the participants were assessed in their physical and mental health using various fitness tests as well as measures of disability and psychological functioning. Participants provided overwhelmingly positive feedback on the program, which was associated with significant improvements in physical and mental health including a significant decrease in body mass index (BMI), blood pressure and increase in stamina. The participants reported lower mean scores on the Patient Health Questionnaire-9 item Scale (PHQ-9), indicating improved psychological well-being. These promising pilot study results from this lifestyle intervention program for elderly Chinese American immigrants with chronic diseases inform the design of a more definitive trial using a randomized design and larger sample size.

Full Text Available Aim In an anthropometric assessment, elderly are frequently unable to measure their height due to mobility and skeletal deformities. An alternative is to use a surrogate value of stature from arm span, knee height, and sitting height. The equations developed for predicting height in Indonesian elderly using these three predictors. The equations put in the nutritional assessment card (NSA of older people. Before the card which is the first new technology in Indonesia will be applied in the community, it should be tested. The study aimed was to conduct diagnostic test of predicted height model in the card compared to actual height.Methods Model validation towards 400 healthy elderly conducted in Jakarta City with cross-sectional design. The study was the second validation test of the model besides Depok City representing semi urban area which was undertaken as the first study.Result Male elderly had higher mean age, height, weight, arm span, knee height, and sitting height as compared to female elderly. The highest correlation between knee height and standing height was similar in women (r = 0.80; P < 0.001 and men (r = 0.78; P < 0.001, and followed by arm span and sitting height. Knee height had the lowest difference with standing height in men (3.13 cm and women (2.79 cm. Knee height had the biggest sensitivity (92.2%, and the highest specificity on sitting height (91.2%.Conclusion Stature prediction equation based on knee-height, arm span, and sitting height are applicable for nutritional status assessment in Indonesian elderly.

Type 2 diabetes (T2DM) is a risk factor for Alzheimer's disease and mild cognitive impairment. The etiology of cognitive impairment in people with T2DM is uncertain but, chronic hyperglycemia, cerebral micro vascular disease, severe hypoglycemia, and increased prevalence of macro vascular disease are implicated. to determine the serum levels of soluble vascular adhesion molecule (sVCAM-1) and highly sensitive C-reactive protein (hs-CRP) in elderly type 2 diabetics with mild cognitive impairment (MCI). Our study was conducted on 90 elderly subjects (aged 60 years old or more). They were divided into Group І, 30 patients with T2DM and mild cognitive impairment, group ІІ, 30 patients with T2DM without cognitive impairment and group III, 30 healthy subjects as a control group. They were subjected to history taking, full clinical examination, anthropometric measurement, the Addenbrooke's Cognitive Examination III (ACE---III 2012), Fasting plasma glucose, 2 hours plasma glucose, HbA1c, lipid profile, protein/creatinine ratio, serum sVCAM-1 and hs-CRP. Serum levels of sVCAM-1 in diabetic elderly patients with MCI were significantly higher (946.7 ± 162.01 ng/ml) than diabetic elderly patients without cognitive impairment (479.06 ± 65.27 ng/ml) and control (263.7 ± 72.05 ng/ml) with (P=0.002). Serum levels of Hs-CRP in diabetic elderly patients with MCI were significantly higher than as diabetic elderly patients without cognitive impairment and control with (P=0.005). Elderly diabetic patients with mild cognitive impairment, have higher levels of soluble adhesion molecules and markers of low-grade systemic inflammation than other groups.

Amenamevir (ASP2151) is a nonnucleoside antiherpesvirus compound available for the treatment of varicella-zoster virus infections. In this article we summarize the findings of four phase 1 studies in healthy participants. Four randomized phase 1 studies investigated the safety and pharmacokinetics of single and multiple doses of amenamevir, including the assessment of age group effect (nonelderly vs elderly), food effect, and the relative bioavailability of two formulations. Amenamevir was administered orally at various doses as a single dose (5-2400 mg) or daily (300 or 600 mg/day) for 7 days. Following single and multiple oral doses, amenamevir demonstrated a less than dose proportional increase in the pharmacokinetic parameters area under the plasma drug concentration versus time curve from time zero to infinity (AUC inf ) and C max . After single and multiple oral 300-mg doses of amenamevir, no apparent differences in pharmacokinetics were observed between nonelderly and elderly participants. In contrast, with the amenamevir 600-mg dose both the area under the plasma drug concentration versus time curve from time zero to 24 h and C max were slightly increased and renal clearance was decreased in elderly participants. The pharmacokinetics of amenamevir was affected by food, with AUC inf increased by about 90%. In the bioavailability study, AUC inf and C max were slightly lower following tablet versus capsule administration (decreased by 14 and 12%, respectively), with relative bioavailability of 86%. The different amenamevir doses and formulations were safe and well tolerated; no deaths or serious adverse events were reported. Amenamevir had less than dose proportional pharmacokinetic characteristics. Age may have an influence on amenamevir pharmacokinetics; however, the effect was considered minimal. The pharmacokinetics of amenamevir were affected by food, with AUC inf almost doubling when amenamevir was administered with food. The concentration versus

The alarming progression of the aging trend in China attracts much attention in the country and abroad. In 2003, the Chinese central government launched the New Cooperative Medical Scheme (NCMS) to resolve the inequity problem of health in regions with inadequate infrastructure and relative poverty. The rural elderly are the main beneficiaries of this policy; the improvement of their health through the medical insurance policy require exploration. This study used data obtained from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) conducted in 2005 and 2008. Elderly people living in rural areas and aged 60 and above were screened for the investigation. A total of 8658 and 9904 elderly people were selected from 2005 and 2008, respectively. By establishing models and employing multi-logistic analysis, stereotype logistic analysis, we examined the effect of NCMS organized by Chinese government on three domains of the health of the rural elderly. A total of 948 and 6361 elderly people participated in NCMS in 2005 (n = 8658) and 2008 (n = 9904), respectively. With regard to the independent variables, the number of participants in NCMS increased, whereas province distribution, gender, and years of education only slightly changed. As for the dependent variables, the rural elderly in 2005 had poor general health but good psychological health. Differences were found between different moods. Old people who engage in much outdoor activity can take care of themselves. After three-year promotion of NCMS, the differences between 2005 and 2008 indicate that the physical function of the rural elderly worsen, whereas the general health and psychological health improves. (1) In the 2005 data and 2008 data, result shows that NCMS participation can promote the self-rated quality and health change of the elderly. (2) After three years, the alleviation effect on anxiety and loneliness changed from insignificant to significant. Participants in NCMS have a stronger sense of
