Burden of care and its impact on health-related quality of life of caregivers of individuals with spinal cord injury

Objective: to analyze the impact and burden of care on the Health-Related Quality of Life (HRQOL) of caregivers of individuals with a spinal cord injury (SCI). Method: cross-sectional observational study carried out by reviewing medical records and applying questionnaires. The scale Short Form 36 (SF-36) was used to assess HRQOL and the Caregiver Burden Scale (CBScale) for care burden. Results were analyzed quantitatively. Most patients with SCIs were male, aged 35.4 years old on average, with a predominance of thoracic injuries followed by cervical injuries. Most caregivers were female aged 44.8 years old on average. Results: tetraplegia and secondary complications stand out among the clinical characteristics that contributed to greater care burden and worse HRQOL. Association between care burden with HRQOL revealed that the greater the burden the worse the HRQOL. Conclusion: Preventing care burden through strategies that prepare patients for hospital discharge, integrating the support network, and enabling access to health care services are interventions that could minimize the effects arising from care burden and contribute to improving HRQOL.

Clinical and sociodemographic factors in a sample of older subjects experiencing depressive symptoms

Objectives This study aims to determine the frequency of clinically significant depressive symptoms (CSDS) in a community sample of older Brazilians and to examine their relationship with sociodemographic factors, cognitive and functional impairment (CFI), and medical illness. Methods A total of 1145 subjects aged 60?years or older living in the City of Ribeirao Preto, State of Sao Paulo, Brazil, were interviewed. The following instruments were used: a 10-item scale for screening of depressive symptoms in older people, the mini mental state examination, the Fuld Object Memory Evaluation, the Informant Questionnaire on Cognitive Decline in the Elderly, the Bayer Activities of Daily Living Scale, and a sociodemographic and clinical questionnaire. Results The frequency of CSDS was 15.7%. Logistic regression analysis indicated that being previously depressed, having CFI, having lower level of education, using psychotropics, and not engaging in physical exercise were related to CSDS. On the other hand, being a woman, older, medically ill, employed, or married was not associated with CSDS. Conclusions Consistent with previous reports, lower education, lack of physical activity, and CFI were significantly associated with higher frequencies of CSDS. Further investigations are necessary to clarify the occurrence of depression and possible modifiable factors in developing countries such as Brazil. Copyright (C) 2011 John Wiley & Sons, Ltd.

Medical adverse events in elderly hospitalized patients: A prospective study

OBJECTIVES: To determine the frequency of medical adverse events in elderly patients admitted to an acute care geriatric unit, the predictive factors of occurrence, and the correlation between adverse events and hospital mortality rates. METHODS: This prospective study included 171 admissions of patients aged 60 years and older in the acute care geriatric unit in a teaching hospital in Brazil between 2007 and 2008. The following variables were assessed at admission: the patient age, gender, number of prescription drugs, geriatric syndromes (e. g., immobility, postural instability, dementia, depression, delirium, and incontinence), comorbidities, functional status (evaluated with the Katz Index of Independence in Activities of Daily Living), and severity of illness (evaluated with the Simplified Acute Physiology Score II). The incidence of delirium, infection, mortality, and the prescription of potentially inappropriate medications (based on the Beers criteria) were assessed during hospitalization. An observer who was uninvolved in patient care reported the adverse events. RESULTS: The mean age of the sample was 78.12 years. A total of 187 medical adverse events occurred in 94 admissions (55%). The predictors of medical adverse events were undetermined. Compared with the patients with no adverse events, the patients with medical adverse events had a significantly longer hospital stay (21.41 +/- 15.08 days versus 10.91 +/- 7.21 days) and a higher mortality rate (39 deaths [41.5%] versus 17 deaths [22.1%]). Mortality was significantly predicted by the Simplified Acute Physiology Score II score (odds ratio [OR] = 1.13, confidence interval [CI] 95%, 1.07 to 1.20), the Katz score (OR = 1.47, CI 95%, 1.18 to 1.83), and medical adverse events (OR = 3.59, CI 95%, 1.55 to 8.30). CONCLUSION: Medical adverse events should be monitored in every elderly hospitalized patient because there is no risk profile for susceptible patients, and the consequences of adverse events are serious, sometimes leading to longer hospital stays or even death.

Mudanças no consumo alimentar e atividade física de escolares de Florianópolis, SC, 2002 - 2007

OBJETIVO: Avaliar a mudança em cinco anos do consumo alimentar e nível de atividade física em escolares. MÉTODOS: Estudo com amostra representativa (n = 4.168) de escolares de sete a dez anos de idade de Florianópolis, SC. Medidas do consumo alimentar e atividade física foram realizadas em dois estudos de base escolar em 2002 (n = 2.936; 51% meninos; idade média = 8,5 anos) e 2007 (n = 1.232; 50,7% meninos; idade média = 8,6 anos), utilizando questionários ilustrados. O teste do qui-quadrado foi utilizado para avaliar a mudança no consumo de oito alimentos/grupos de alimentos, no atendimento às recomendações do Guia Alimentar para a População Brasileira e no nível de atividade física (avaliado segundo os terços de distribuição do escore e o tipo de deslocamento para a escola). As análises foram realizadas segundo a rede de ensino. RESULTADOS: Houve redução da proporção de crianças que relatou o consumo de frutas, verduras e legumes, feijão, carnes, guloseimas, pizza, batata frita e refrigerantes. Maior proporção de escolares da rede privada atendeu às recomendações de restrição de consumo de refrigerantes, pizzas e batata frita, e de maior consumo de frutas, verduras e legumes, em ambos os estudos. Por outro lado, maior proporção de escolares da rede pública atendeu às recomendações para o consumo de carnes em 2007. Os valores medianos do escore de atividade física diminuíram em 2007. Em ambos os anos escolares da rede privada foram mais ativos. A proporção de escolares que se deslocou ativamente para a escola reduziu de 49% para 41% (p < 0,01). CONCLUSÕES: Houve redução no consumo de alimentos marcadores de dieta saudável (feijão, carnes/peixes, frutas, legumes e verduras) e de alimentos de alta densidade energética e baixo valor nutricional (refrigerantes, guloseimas e pizza/batatas fritas). Também houve decréscimo da proporção de escolares que relataram deslocamento ativo para a escola.

Assessment of functional capacity of the elderly associated with the risk for pressure ulcer

OBJECTIVE: To characterize the elderly with physical limitations; to assess functional capacity as it relates to physical mobility, cognitive status and level of functional independence in activities of daily living, and to relate functional capacity to the risk for pressure ulcers. METHODS: A quantitative cross-sectional approach, conducted in households in the city of João Pessoa (PB) with seniors who presented physical limitation. Fifty-one elderly were investigated in a two-stage cluster sampling design. RESULTS: There was evidence of impairments in functional capacity of the elderly aged 80 years or more, with more severe physical limitations, cognitive impairment and a higher level of dependency for activities. Significant differences were observed between the level of functional independence in performing activities of daily living and the risk of pressure ulcers. CONCLUSION: This study allowed for the identification of the elderly in functional decline and at risk for developing pressure ulcers, supporting the implementation of preventive actions at the household level.

Functional independence in patients with chronic kidney disease being treated with haemodialysis¹

PURPOSE: This study has described and analysed the functional independence of the patients served in the haemodialysis services of a countryside town in the State of São Paulo, Brazil, using the Functional Independence Measure (FIM). METHOD: The population considered was that of 214 patients being treated with haemodialysis, assessed in 2011, by means of a social, demographic and clinical report, a Mini-Mental State Examination (MMSE) and also the FIM. RESULTS: The mean age of the population under study was 58.01 years, while the mean FIM point score was 118.38 points, showing a level of complete or modified independence within this population. Even though the level of dependence found has been low, this can be highlighted, within the locomotion domain, in the activity of going up and down stairs (10.28%). Age, complications arising from haemodialysis, and comorbidities show a negative correlation with FIM. CONCLUSION: Awareness of the level of functional independence of the patients being subjected to treatment with haemodialysis is essential in order to back up intervention for the improvement of nursing assistance provided to this population.

Exercício aeróbico ou com pesos melhora o desempenho nas atividades da vida diária de mulheres idosas

Este estudo aleatorizado não controlado teve como objetivo determinar o efeito de um protocolo de exercício com pesos ou aeróbico no desempenho das atividades da vida diária em mulheres idosas. Para tanto, a amostra foi constituída por 41 mulheres idosas aparentemente saudáveis na faixa etária de 60 a 85 anos de idade (x: 65,1 ± 7,9 anos) divididas aleatoriamente em grupo exercício com pesos (n: 22) ou aeróbico (n: 19). O grupo exercício com pesos consistiu na execução de três séries de oito a 12 repetições a 60% de uma repetição máxima no exercício leg press 45º. O grupo exercício aeróbico consistiu em pedalar em cicloergômetro durante 40 minutos a 60% da frequência cardíaca de reserva. Os dois protocolos foram realizados três vezes por semana durante cinco semanas. As atividades da vida diária selecionadas foram velocidade para se levantar de uma posição sentada (VLPS), velocidade para se levantar de uma posição deitada (VLPD), velocidade para subir escada (VSE) e velocidade para calçar e amarrar o tênis (VCAT). O grupo exercício aeróbico melhorou significativamente o desempenho em VCAT (19,1%), enquanto o exercício com pesos incrementou significativamente o desempenho em VSE (4,3%) e VLPS (8,9%). Os resultados deste estudo permitem concluir que tanto o exercício com pesos como o aeróbico induziram efeito positivo nas atividades da vida diária, sugerindo que ambas as modalidades de exercício devem ser associadas a um programa adequado de exercícios para a melhora da capacidade funcional de pessoas idosas.

Dificuldades para atividades básicas e instrumentais de vida diária, referidas por usuários de um centro de saúde escola do município de São Paulo

Idosos que atendem a determinados critérios demográficos, sociais e econômicos estão especialmente vulneráveis a adoecimento, incapacidades e morte. Desenvolveu-se estudo com o objetivo de identificar idosos vulneráveis segundo critérios determinados e comparar idosos vulneráveis e não-vulneráveis em relação à necessidade de ajuda para atividades. O estudo, de corte transversal, compreendeu coleta de dados com 190 idosos usuários de um Centro de Saúde Escola, em seus domicílios, entre 2006 e 2008, por meio de aplicação do Instrumento para Classificação de Idosos quanto à Capacidade para o Autocuidado. Cento e quarenta e cinco idosos (80%) estão submetidos a pelo menos um critério de risco; 99 (52,1%) referem uma ou mais dificuldades para atividades básicas, sendo que 29 (29,3%) requerem ajuda; 92 (48,4%) idosos mencionam dificuldades para atividades instrumentais e destes, 67 (72,8%) requerem ajuda. Somente 16 (8,4%) adotam práticas de autocuidado para minimizar suas dificuldades e 38 (20%) as adotam para compensar parte delas. O grupo de idosos que atende pelo menos a um critério de risco apresenta proporção maior de indivíduos que requer ajuda para atividades básicas e instrumentais de vida diária. Outras análises possibilitarão verificar a influência de cada critério sobre a funcionalidade. A realização de pesquisa sobre práticas de autocuidado com um maior número de indivíduos possibilitará comparação entre grupos que empregam ou não essas práticas e critérios de risco. Apesar das limitações do estudo, ele suscita planejamento de ações aos idosos com dificuldades e que requeiram ou não ajuda para suas atividades.

Development of musculoskeletal models for the design and the pre-clinical validation of hip resurfacing prosthesis

Background. The surgical treatment of dysfunctional hips is a severe condition for the patient and a costly therapy for the public health. Hip resurfacing techniques seem to hold the promise of various advantages over traditional THR, with particular attention to young and active patients. Although the lesson provided in the past by many branches of engineering is that success in designing competitive products can be achieved only by predicting the possible scenario of failure, to date the understanding of the implant quality is poorly pre-clinically addressed. Thus revision is the only delayed and reliable end point for assessment. The aim of the present work was to model the musculoskeletal system so as to develop a protocol for predicting failure of hip resurfacing prosthesis. Methods. Preliminary studies validated the technique for the generation of subject specific finite element (FE) models of long bones from Computed Thomography data. The proposed protocol consisted in the numerical analysis of the prosthesis biomechanics by deterministic and statistic studies so as to assess the risk of biomechanical failure on the different operative conditions the implant might face in a population of interest during various activities of daily living. Physiological conditions were defined including the variability of the anatomy, bone densitometry, surgery uncertainties and published boundary conditions at the hip. The protocol was tested by analysing a successful design on the market and a new prototype of a resurfacing prosthesis. Results. The intrinsic accuracy of models on bone stress predictions (RMSE < 10%) was aligned to the current state of the art in this field. The accuracy of prediction on the bone-prosthesis contact mechanics was also excellent (< 0.001 mm). The sensitivity of models prediction to uncertainties on modelling parameter was found below 8.4%. The analysis of the successful design resulted in a very good agreement with published retrospective studies. The geometry optimisation of the new prototype lead to a final design with a low risk of failure. The statistical analysis confirmed the minimal risk of the optimised design over the entire population of interest. The performances of the optimised design showed a significant improvement with respect to the first prototype (+35%). Limitations. On the authors opinion the major limitation of this study is on boundary conditions. The muscular forces and the hip joint reaction were derived from the few data available in the literature, which can be considered significant but hardly representative of the entire variability of boundary conditions the implant might face over the patients population. This moved the focus of the research on modelling the musculoskeletal system; the ongoing activity is to develop subject-specific musculoskeletal models of the lower limb from medical images. Conclusions. The developed protocol was able to accurately predict known clinical outcomes when applied to a well-established device and, to support the design optimisation phase providing important information on critical characteristics of the patients when applied to a new prosthesis. The presented approach does have a relevant generality that would allow the extension of the protocol to a large set of orthopaedic scenarios with minor changes. Hence, a failure mode analysis criterion can be considered a suitable tool in developing new orthopaedic devices.

Reversed shoulder arthroplasty with modified L'Episcopo for combined loss of active elevation and external rotation

In patients with a rotator cuff-deficient shoulder, a combined loss of active elevation and external rotation (CLEER) can occur when both the infraspinatus and teres minor muscles are absent. A reverse shoulder arthroplasty (RSA) can restore active elevation in these patients but cannot restore active external rotation because there are no other external rotator cuff muscles. We hypothesized that a modified L'Episcopo procedure (latissimus dorsi [LD] and teres major [TM] transfer) with a simultaneous RSA would restore shoulder function and activities of daily living (ADLs).

Delirium upon admission to Swiss nursing homes

QUESTIONS UNDER STUDY: We wished to investigate the prevalence of delirium in patients upon admission to nursing homes and whether or not the previous place of residence predicts delirium. METHODS: The Resident Assessment Instrument Minimum Data Set (RAI-MDS) and the Nursing Home Confusion Assessment Method (NHCAM) were used to determine whether the previous place of residence (community, nursing home, acute care, psychiatric, rehabilitation hospital) predicted the prevalence of sub-syndromal or full delirium in nursing home residents in three Swiss cantons (n = 11745). RESULTS: 39.7% had sub-syndromal and 6.5% had full delirium. Lower cognitive performance and increased depressive symptoms were significant predictors of higher NHCAM values independent of previous residence. Age, civil status, continence, newly introduced drugs, and basic activities of daily living were predictors in some resident groups. The variance of NHCAM scores explained varied between 25.1% and 32.3% depending on previous residence. CONCLUSIONS: Sub-syndromal and full delirium are common upon nursing home admission. Increased dependence and depression are consistently associated with higher NHCAM scores. Patients from psychiatric settings have an increased risk of delirium. Although factors associated with delirium depend on a patient's previous residence, all patients must be carefully screened for sub-syndromal and full delirium.

Apraxia in neurorehabilitation: Classification, assessment and treatment

Apraxia is a higher-order motor disorder impairing the ability to correctly perform skilled, purposive movements as the result of neurological disorders most commonly stroke, dementia and movement disorders. It is increasingly recognised that apraxia negatively influences activities of daily living (ADL). Early diagnosis and treatment should be part of the neurorehabilitation programme. The aim of the present article is to describe the most important subtypes of apraxia such as ideational and ideomotor apraxia as well as their impact on ADL and outcome. Furthermore, the relationship to associated disorders such as aphasia is discussed. Finally, strategies concerning assessment, management and treatment of the disorder are presented.

Domains of physical activity and all-cause mortality: systematic review and dose-response meta-analysis of cohort studies

Background The dose–response relation between physical activity and all-cause mortality is not well defined at present. We conducted a systematic review and meta-analysis to determine the association with all-cause mortality of different domains of physical activity and of defined increases in physical activity and energy expenditure. Methods MEDLINE, Embase and the Cochrane Library were searched up to September 2010 for cohort studies examining all-cause mortality across different domains and levels of physical activity in adult general populations. We estimated combined risk ratios (RRs) associated with defined increments and recommended levels, using random-effects meta-analysis and dose–response meta-regression models. Results Data from 80 studies with 1 338 143 participants (118 121 deaths) were included. Combined RRs comparing highest with lowest activity levels were 0.65 [95% confidence interval (95% CI) 0.60–0.71] for total activity, 0.74 (95% CI 0.70–0.77) for leisure activity, 0.64 (95% CI 0.55–0.75) for activities of daily living and 0.83 (95% CI 0.71–0.97) for occupational activity. RRs per 1-h increment per week were 0.91 (95% CI 0.87–0.94) for vigorous exercise and 0.96 (95% CI 0.93–0.98) for moderate-intensity activities of daily living. RRs corresponding to 150 and 300 min/week of moderate to vigorous activity were 0.86 (95% CI 0.80–0.92) and 0.74 (95% CI 0.65–0.85), respectively. Mortality reductions were more pronounced in women. Conclusion Higher levels of total and domain-specific physical activity were associated with reduced all-cause mortality. Risk reduction per unit of time increase was largest for vigorous exercise. Moderate-intensity activities of daily living were to a lesser extent beneficial in reducing mortality.

Predictors of functional decline in elderly patients undergoing transcatheter aortic valve implantation (TAVI)

Aims This study aimed to assess functional course in elderly patients undergoing transcatheter aortic valve implantation (TAVI) and to find predictors of functional decline. Methods and results In this prospective cohort, functional course was assessed in patients ≥70 years using basic activities of daily living (BADL) before and 6 months after TAVI. Baseline EuroSCORE, STS score, and a frailty index (based on assessment of cognition, mobility, nutrition, instrumental and basic activities of daily living) were evaluated to predict functional decline (deterioration in BADL) using logistic regression models. Functional decline was observed in 22 (20.8%) of 106 surviving patients. EuroSCORE (OR per 10% increase 1.18, 95% CI: 0.83-1.68, P = 0.35) and STS score (OR per 5% increase 1.64, 95% CI: 0.87-3.09, P = 0.13) weakly predicted functional decline. In contrast, the frailty index strongly predicted functional decline in univariable (OR per 1 point increase 1.57, 95% CI: 1.20-2.05, P = 0.001) and bivariable analyses (OR: 1.56, 95% CI: 1.20-2.04, P = 0.001 controlled for EuroSCORE; OR: 1.53, 95% CI: 1.17-2.02, P = 0.002 controlled for STS score). Overall predictive performance was best for the frailty index [Nagelkerke's R(2) (NR(2)) 0.135] and low for the EuroSCORE (NR(2) 0.015) and STS score (NR(2) 0.034). In univariable analyses, all components of the frailty index contributed to the prediction of functional decline. Conclusion Over a 6-month period, functional status worsened only in a minority of patients surviving TAVI. The frailty index, but not established risk scores, was predictive of functional decline. Refinement of this index might help to identify patients who potentially benefit from additional geriatric interventions after TAVI.
