Perceived stress in elderly stroke survivors after hospital discharge to home

AbstractOBJECTIVETo evaluate the relationship between perceived stress and comorbidities, neurological deficit, functional independence and depressive symptoms of stroke survivors after hospital discharge.METHODCross-sectional study with 90 elderly stroke survivors. The National Institutes of Health Stroke Scale instrument, the Functional Independence Measure instrument, the Geriatric Depression Scale and the Perceived Stress Scale were used. Bivariate Pearson correlation, independent t test and multiple regression analysis were used to evaluate the relationship between perceived stress and other variables.RESULTSThe final regression model showed that higher perceived stress was related to less functional independence (p= 0.022) and more depressive symptoms (p <0.001).CONCLUSIONAt hospital discharge, interventions should be planned for the treatment of depressive symptoms and to create adaptation strategies to the reduction of functional independence, in order to reduce the stress of the survivors.

Pain intensity among institutionalized elderly: a comparison between numerical scales and verbal descriptors

AbstractOBJECTIVECorrelating two unidimensional scales for measurement of self-reported pain intensity for elderly and identifying a preference for one of the scales.METHODA study conducted with 101 elderly people living in Nursing Home who reported any pain and reached ( 13 the scores on the Mini-Mental State Examination. A Numeric Rating Scale - (NRS) of 11 points and a Verbal Descriptor Scale (VDS) of five points were compared in three evaluations: overall, at rest and during movement.RESULTSWomen were more representative (61.4%) and the average age was 77.0±9.1 years. NRS was completed by 94.8% of the elderly while VDS by 100%. The association between the mean scores of NRS with the categories of VDS was significant, indicating convergent validity and a similar metric between the scales.CONCLUSIONPain measurements among institutionalized elderly can be made by NRS and VDS; however, the preferred scale for the elderly was the VDS, regardless of gender.

Physical activity modulates heat shock protein-72 expression and limits oxidative damage accumulation in a healthy elderly population aged 60 90 years

BACKGROUND: Reactive oxygen species production increases during aging, whereas protective mechanisms such as heat shock proteins (HSPs) or antioxidant capacity are depressed. Physical activity has been hypothesized to provide protection against oxidative damage during aging, but results remain controversial. This study aimed to investigate the effect of different levels of physical activity during aging on Hsp72 expression and systemic oxidative stress at rest and in response to maximal exercise. METHODS: Plasma antioxidant capacity (Trolox equivalent antioxidant capacity, TEAC), thiobarbituric acid-reactive species (TBARS), advanced oxidized proteins products (AOPP), and Hsp72 expression in leukocytes were measured before and after maximal exercise testing in 32 elderly persons (aged 73.2 years), who were assigned to two different groups depending on their level of physical activity during the past 12 months (OLow = moderate to low level; OHigh = higher level). RESULTS: The OHigh group showed higher aerobic fitness and TEAC (both representing 120% of OLow values) as well as lower oxidative damage (50% of OLow values) and Hsp72 expression. Exercise led to a lower increase in oxidative damage in the OHigh group. Aerobic fitness was positively correlated with TEAC and negatively with lipid peroxidation (TBARS). Hsp72 expression was negatively correlated with TEAC but positively correlated with TBARS levels. CONCLUSIONS: The key finding of this study is that, in people aged 60 to 90 years, long-term high level of physical activity preserved antioxidant capacity and limited oxidative damage accumulation. It also downregulated Hsp72 expression, an adaptation potentially resulting from lower levels of oxidative damage.

Handgrip strength and physical activity in frail elderly

Abstract OBJECTIVE To investigate the association between handgrip strength (HS) and physical activity in physical frailty elderly. METHOD Cross-sectional quantitative study with a sample of 203 elderly calculated based on the population estimated proportion. Tests were applied to detect cognitive impairment and assessment of physical frailty. Descriptive statistics and multivariate analysis by binary logistic regression were used, and also Student's t-test and Fisher's exact test. RESULTS A total of 99 (64.3%) elderly showed decreased handgrip strength and 90 (58.4%) elderly presented decrease in physical activity levels. There was a statistically significant difference between these two components (p=0.019), in which elderly who have decreased HS have lower levels of physical activity. For low levels of physical activity and decreased HS, there was no evidence of significant difference in the probability of the classification as frail elderly (p<0.001). CONCLUSION The components handgrip strength and physical activity are associated with the frail elderly. The joint presence of low levels of physical activity and decreased handgrip strength leads to a significantly higher probability of the elderly to be categorized as frailty.

An integrative review of drug utilization by the elderly in primary health care

ABSTRACT OBJECTIVE To identify knowledge produced about drug utilization by the elderly in the primary health care context from 2006 to 2014. METHOD An integrative review of the PubMed, LILACS, BDENF, and SCOPUS databases, including qualitative research papers in Portuguese, English, and Spanish. It excluded papers with insufficient information regarding the methodological description. RESULTS Search found 633 papers that, after being subjected to the inclusion and exclusion criteria, made up a corpusof 76 publications, mostly in English and produced in the United States, England, and Brazil. Results were pooled in eight thematic categories showing the current trend of drug use in the elderly, notably the use of psychotropics, polypharmacy, the prevention of adverse events, and adoption of technologies to facilitate drug management by the elderly. Studies point out the risks posed to the elderly as a consequence of changes in metabolism and simultaneous use of several drugs. CONCLUSION There is strong concern about improving communications between professionals and the elderly in order to promote an exchange of information about therapy, and in this way prevent major health complications in this population.

The drift of public spending towards the elderly: A generational analysis of the trend of public policies in Spain

The tendency for public welfare spending to be increasingly aimed at the elderly has been pointed out for the US and other developed countries. While population ageing is a common trend, it is not obvious why the shift in spending exceeds the trend in ageing, or why per capita spending on the elderly increases.We show that this is the case in Spain, identify the losers from this development, discuss the policies that underlie this trend, and propose adjustments based on Musgrave s fixed proportions rule as an inter-generationally fair distribution.

Biomechanical characterization and in vitro mechanical injury of elderly human femoral head cartilage: comparison to adult bovine humeral head cartilage.

OBJECTIVES: In vitro mechanical injury of articular cartilage is useful to identify events associated with development of post-traumatic osteoarthritis (OA). To date, many in vitro injury models have used animal cartilage despite the greater clinical relevance of human cartilage. We aimed to characterize a new in vitro injury model using elderly human femoral head cartilage and compare its behavior to that of an existing model with adult bovine humeral head cartilage. DESIGN: Mechanical properties of human and bovine cartilage disks were characterized by elastic modulus and hydraulic permeability in radially confined axial compression, and by Young's modulus, Poisson's ratio, and direction-dependent radial strain in unconfined compression. Biochemical composition was assessed in terms of tissue water, solid, and glycosaminoglycan (GAG) contents. Responses to mechanical injury were assessed by observation of macroscopic superficial tissue cracks and histological measurements of cell viability following single injurious ramp loads at 7 or 70%/s strain rate to 3 or 14 MPa peak stress. RESULTS: Confined compression moduli and Young's moduli were greater in elderly human femoral cartilage vs adult bovine humeral cartilage whereas hydraulic permeability was less. Radial deformations of axially compressed explant disks were more anisotropic (direction-dependent) for the human cartilage. In both cartilage sources, tissue cracking and associated cell death during injurious loading was common for 14 MPa peak stress at both strain rates. CONCLUSION: Despite differences in mechanical properties, acute damage induced by injurious loading was similar in both elderly human femoral cartilage and adult bovine humeral cartilage, supporting the clinical relevance of animal-based cartilage injury models. However, inherent structural differences such as cell density may influence subsequent cell-mediated responses to injurious loading and affect the development of OA.

Différences régionales de l'incidence des fractures de la hanche dues à l'ostéoporose chez les femmes âgées : influence de la condition physique et de la nutrition

Résumé L'ostéoporose est une maladie systémique du squelette caractérisée par une fragilité osseuse augmentée avec pour conséquence une augmentation de la susceptibilité aux fractures. C'est actuellement un important problème de santé publique avec des conséquences majeures pour les systèmes de soins tant d'un point de vue médical que financier. Les projections mondiales prévoient une augmentation significative du nombre de fractures de la hanche d'ici 2050. Cette étude vise à analyser l'influence des apports nutritionnels par rapport à celle de la condition physique sur le risque de fracture ostéoporotique en reprenant les données évaluant la consommation de produits laitiers au sein du collectif de l'étude SEMOF («Evaluation suisse de méthodes de mesure du risque de fracture ostéoporotique»). Nous avons d'abord montré que les apports moyens en calcium des 7788 femmes âgées de 70 ans et plus ayant participé à l'étude sont inférieurs aux recommandations suisses et internationales. Des trois régions étudiées, la Suisse romande est celle où les apports quotidiens moyens en calcium et en protéines provenant des produits laitiers sont les plus faibles et où l'incidence des fractures de la hanche secondaires à l'ostéoporose est la plus élevée. Les apports en calcium et en protéines sont également plus élevés à la campagne par rapport à la ville alors que l'incidence des fractures de la hanche n'est pas significativement différente entre ville et campagne. De plus, nous avons montré que les apports quotidiens moyens en calcium et en protéines provenant des produits laitiers ne diffèrent pas significativement entre les femmes avec ou sans fracture de la hanche pendant le suivi. En revanche, la condition physique des femmes qui ont présenté une fracture de la hanche est significativement moins bonne. Sur la base de données anamnestiques concernant les facteurs de risque de chute et la mobilité, nous avons développé un score permettant d'identifier les femmes les plus à risque de chute. La condition physique de ces femmes, attestée par le test de la chaise et la mesure de la force de préhension est la moins bonne. Toutefois, leurs apports quotidiens moyens en calcium et en protéines provenant des produits laitiers ne diffèrent pas significativement par rapport aux femmes à faible risque de chute. En conclusion, le risque de fracture de la hanche liée à l'ostéoporose est plus élevé chez les femmes de plus de 70 ans vivant en Suisse romande que dans les deux autres régions linguistiques. Il est déterminé avant tout par le risque de chute et par la condition physique. Les apports en calcium et en protéines provenant des produits laitiers, tels que nous les avons évalués ne semblent pas déterminants.

Assessing the wish to die in elderly people.

Background: The wish to die has mainly been studied in terminally- ill young adults. In elderly persons, factors associated with the wish to die are likely to differ from those observed in younger people. Since the most frequently used scale -"The Schedule ofAttitudes Toward Hastened Death" (SAHD, Rosenfeld et al., 2000)- was previously used in terminally ill cancer or AIDS patients, its use in elderly people suffering from multiple comorbidities is problematic. The objectives of this study were 1) to adapt the SAHD for use in elderly people, 2) to develop a new instrument to assess patients' attitudes towards death 3) to test the relevance/acceptability of these instruments. Methods:An adapted version of the SAHD to the elderly population (SAHD-OLD) was obtained by analyzing all items of the instrument instrument in an interdisciplinary group of experts in geriatric care. Items were modified according to their relevance in elderly population. An instrument to assess patients' attitudes towards death was built on previous qualitative work performed by Schroepfer. These 2 instruments were subjected to cognitive testing in a convenience sample of 11 community-dwelling people (median age = 82 years; range 76-91). Results: The SAHD-OLD was obtained by modifying those items addressing palliative care issues (eg. irreversible consequences of stopping treatment) and systematically replacing "illness/disease" by "health problems". We expressed in statements the 6 categories identified by Schroepfer, and created instructions asking respondents to describe their current attitude towards death (Adapted Schroepfer). During cognitive testing, our sample assessed the SAHD-OLD and the Adapted Schroepfer as relevant for elderly people. Respondents judged these 2 instruments acceptable and appreciated the direct manner in which they addressed end of life issues. The opportunity to speak openly on this topic was welcomed. Conclusions: The SAHD-OLD and the Adapted Schroepfer seem promising instruments to assess the wish to die in elderly people suffering from multiple comorbidities. Preliminary results show good comprehension, high relevance and acceptability. Psychometric properties of the SAHD-OLD are currently being tested in a large sample of patients.

Les troubles psychiatriques des patients âgés avec une maladie de Parkinson et leurs traitements [Psychiatric disorders in elderly patients with Parkinson's disease and their treatments].

Parkinson's disease (PD) is a neuropsychiatric disorder. During the course of PD, most patients develop at least one psychiatric syndrome. Depression is the most frequent disorder and affects nearly half of all patients. The use of an increasing number of new drugs, in particular the dopaminergic agents, puts these patients at risk of developing both delirium and psychosis. This article summarizes the different psychiatric syndromes seen in PD and gives an account of the various treatment possibilities.

Vitamin C requirements in parenteral nutrition.

Some biochemical functions of vitamin C make it an essential component of parenteral nutrition (PN) and an important therapeutic supplement in other acute conditions. Ascorbic acid is a strong aqueous antioxidant and is a cofactor for several enzymes. The average body pool of vitamin C is 1.5 g, of which 3%-4% (40-60 mg) is used daily. Steady state is maintained with 60 mg/d in nonsmokers and 140 mg/d in smokers. Shocked surgical, trauma, and septic patients have a drastic reduction of circulating plasma ascorbate concentrations. These low concentrations require 3-g doses/d to restore normal plasma ascorbate concentrations, questioning the recommended PN dose of 100 mg/d. Determination of intravenous requirements is usually based on plasma concentrations, which are altered during the inflammatory response. There is no clear indicator of deficiency: serum or plasma ascorbate concentrations <0.3 mg/dL (20 micromol/L) indicates inadequate vitamin C status. On the basis of available pharmacokinetic data the 100 mg/d dose for patients receiving home PN and 200 mg/d for stable adult patients receiving PN are adequate, but requirements have been shown to be higher in perioperative, trauma, burn, and critically ill patients, paralleling oxidative stress. One recommendation cannot fit all categories of patients. Large vitamin C supplements may be considered in severe critical illness, major trauma, and burns because of increased requirements resulting from oxidative stress and wound healing. Future research should distinguish therapeutic use of high-dose ascorbic acid antioxidant therapy from nutritional PN requirements.

The spiritual distress assessment tool: an instrument to assess spiritual distress in hospitalised elderly persons.

BACKGROUND: Although spirituality is usually considered a positive resource for coping with illness, spiritual distress may have a negative influence on health outcomes. Tools are needed to identify spiritual distress in clinical practice and subsequently address identified needs. This study describes the first steps in the development of a clinically acceptable instrument to assess spiritual distress in hospitalized elderly patients. METHODS: A three-step process was used to develop the Spiritual Distress Assessment Tool (SDAT): 1) Conceptualisation by a multidisciplinary group of a model (Spiritual Needs Model) to define the different dimensions characterizing a patient's spirituality and their corresponding needs; 2) Operationalisation of the Spiritual Needs Model within geriatric hospital care leading to a set of questions (SDAT) investigating needs related to each of the defined dimensions; 3) Qualitative assessment of the instrument's acceptability and face validity in hospital chaplains. RESULTS: Four dimensions of spirituality (Meaning, Transcendence, Values, and Psychosocial Identity) and their corresponding needs were defined. A formalised assessment procedure to both identify and subsequently score unmet spiritual needs and spiritual distress was developed. Face validity and acceptability in clinical practice were confirmed by chaplains involved in the focus groups. CONCLUSIONS: The SDAT appears to be a clinically acceptable instrument to assess spiritual distress in elderly hospitalised persons. Studies are ongoing to investigate the psychometric properties of the instrument and to assess its potential to serve as a basis for integrating the spiritual dimension in the patient's plan of care.
