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.

Revisão sistemática das escalas utilizadas para avaliação funcional na doença de Pompe

OBJETIVO: Identificar as escalas utilizadas para avaliação funcional na doença de Pompe (DP) e descrever seu nível de evidência e recomendação. FONTES DE DADOS: Revisão sistemática sobre as escalas de avaliação funcional na DP. Pesquisa realizada nos bancos de dados Medline, Lilacs, Registro Cochrane de Ensaios Controlados Central (CCTR) e SciELO com artigos (exceto artigos de revisão) publicados entre 2000 e 2010. As palavras-chave utilizadas nos idiomas português e inglês foram: doença de depósito de glicogênio tipo II, atividades cotidianas, avaliação. Os artigos foram classificados em nível de evidência e recomendação. SÍNTESE DOS DADOS: Foram incluídos 14 estudos que avaliaram desde recém-nascidos a adultos (amostra total=449). Foram encontradas as seguintes escalas na literatura: Pediatric Evaluation of Disability Inventory (PEDI) e sua forma adaptada para DP (Pompe-PEDI), Alberta Infant Motor Scale (AIMS), Rotterdam Handiscap Scale (RHS), Functional Independence Measure (FIM), Gross Motor Function Measure (GMFM) e Peabody Developmental Motor Scales (PDMS-II). A maioria dos estudos apresentou nível de evidência III, por serem não randomizados. Grau de recomendação das escalas: C para AIMS e Pompe-PEDI; D para GMFM e PDMS-II; E para RHS e FIM. CONCLUSÕES: A maioria das escalas utilizadas para avaliação funcional na DP apresenta baixo nível de evidência e recomendação. As que apresentam melhor grau de recomendação (C) são as escalas AIMS e Pompe-PEDI aplicadas em Pediatria.

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.

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.

Exploring Assistance in Sweden and the United States

Few international comparisons of health services are performed using microlevel data. Using such data, this paper compares the need for and receipt of assistance with activities of daily living (ADLs) in comparable samples in the United States and Sweden, a country with a universal system of community-based services.Design and Methods: Data from national surveys of community residents completed at approximately the same time in each nation are used to create comparable measures of need and assistance. Descriptive and logistic regression analyses compare need and assistance patterns across the nations and identify individual factors that explain receipt of assistance and unmet needs.Results:Our results indicate that a simple story of greater use of paid formal services in Sweden and more unpaid informal use in the United States masks a more complex relationship. Assistance with ADLs seems to be more targeted in Sweden; narrow differences in assistance widen considerably when the analysis is limited to those reporting need. Implications:Although these two different health systems result in similar levels of overall ADL assistance, a detailed microlevel comparison reveals key distinctions. Further microlevel comparisons of access, cost, and quality in cross-national data can further aid our understanding of the consequences of health policy.

Long-term pallidal deep brain stimulation in patients with advanced Parkinson disease: 1-year follow-up study

OBJECT: The goal of this study was to investigate the efficacy of long-term deep brain stimulation (DBS) of the posteroventral lateral globus pallidus internus (GPi) accomplished using a single-contact monopolar electrode in patients with advanced Parkinson disease (PD). METHODS: Sixteen patients suffering from severe PD and levodopa-induced side effects such as dyskinesias and on-off fluctuations were enrolled in a prospective study protocol. There were six women and 10 men and their mean age at surgery was 65 years. All patients underwent implantation of a monopolar electrode in the posteroventral lateral GPi. Initially, nine patients received unilateral stimulation. Three of these patients underwent contralateral surgery at a later time. Ten patients received bilateral stimulation (contemporaneous bilateral surgery was performed in seven patients and staged bilateral surgery in the three patients who had received unilateral stimulation initially). Formal assessments were performed during both off-medication and on-medication (levodopa) periods preoperatively, and at 3 and 12 months postoperatively. There were no serious complications related to surgery or to DBS. Two transient adverse events occurred: in one patient a small pallidal hematoma developed, resulting in a prolonged micropallidotomy effect, and in another patient a subcutaneous hemorrhage occurred at the site of the pacemaker. In patients who received unilateral DBS, the Unified Parkinson's Disease Rating Scale activities of daily living (ADL) score during the off-levodopa period decreased from 30.8 at baseline to 20.4 at 3 months (34% improvement) and 20.6 at 12 months (33% improvement) postoperatively. The motor score during the off period improved from 57.2 at baseline to 35.2 at 3 months (38% improvement) and 35.3 at 12 months (38% improvement) postoperatively. Bilateral DBS resulted in a reduction in the ADL score during the off period from 34.9 at baseline to 22.3 at 3 months (36% improvement) and 22.9 at 12 months (34% improvement). The motor score for the off period changed from 63.4 at baseline to 40.3 at 3 months (36% improvement) and 37.5 at 12 months (41% improvement). In addition, there were significant improvements in patients' symptoms during the on period and in on-off motor fluctuations. CONCLUSIONS: Pallidal DBS accomplished using a monopolar electrode is a safe and effective procedure for treatment of advanced PD. Compared with pallidotomy, the advantages of pallidal DBS lie in its reversibility and the option to perform bilateral surgery in one session. Comparative studies in which DBS is applied to other targets are needed.

Personal mastery is associated with reduced sympathetic arousal in stressed Alzheimer caregivers

OBJECTIVES: Spousal caregivers of Alzheimer's disease patients are at increased risk for cardiovascular disease, possibly via sympathetic response to stressors and subsequent catecholamine surge. Personal mastery (i.e., belief that one can manage life's obstacles) may decrease psychological and physiological response to stressors. This study examines the relationship between mastery and sympathetic arousal in elderly caregivers, as measured by norepinephrine (NE) reactivity to an acute psychological stressor. DESIGN: Cross-sectional. SETTING: Data were collected by a research nurse in each caregiver's home. PARTICIPANTS: Sixty-nine elderly spousal Alzheimer caregivers (mean age: 72.8 years) who were not taking beta-blocking medication. INTERVENTION: After assessment for mastery and objective caregiving stressors, caregivers underwent an experimental speech task designed to induce sympathetic arousal. MEASUREMENTS: Mastery was assessed using Pearlin's Personal Mastery scale and Alzheimer patient functioning was assessed using the Clinical Dementia Rating Scale, Problem Behaviors Scale, and Activities of Daily Living Scale. Plasma NE assays were conducted using pre- and postspeech blood draws. RESULTS: Multiple regression analyses revealed that mastery was significantly and negatively associated with NE reactivity (B = -9.86, t (61) = -2.03, p = 0.046) independent of factors theoretically and empirically linked to NE reactivity. CONCLUSIONS: Caregivers with higher mastery had less NE reactivity to the stressor task. Mastery may exert a protective influence that mitigates the physiological effects of acute stress, and may be an important target for psychosocial interventions in order to reduce sympathetic arousal and cardiovascular stress among dementia caregivers.

The relationship between pain intensity and severity and depression in older people: exploratory study

BACKGROUND: Pain and depression are known to be associated in later life, and both have a negative effect on physical performance both separately and in combination. The nature of the relationships between pain intensity and depression in elderly persons experiencing pain is less clear. The objectives of this study were to explore which factors are associated with depressed mood in older people experiencing pain, and to test the hypothesis that older people experiencing pain are at risk of depressed mood according to the severity or frequency of their pain. In addition we explored whether other potentially modifiable factors might increase the risk of depressed mood in these persons. METHODS: The study is a secondary analysis of baseline data for four hundred and six community-dwelling non-disabled people aged 65 and over registered with three group practices in suburban London who had experienced pain in the past 4 weeks. Intensity and frequency of pain was measured using 24 item Geriatric Pain Measure (GPM) and the presence of depressive symptoms using the 5 item Mental Health Inventory. Risk for social isolation was measured using the 6 item Lubben Social Network scale and instrumental activities of daily living (IADL) were also measured. RESULTS: Overall 76 (19%) had depressed mood. Pain frequency and severity were not statistically significantly associated with depressed mood in this population. In multivariate analyses, significant predictors of the presence of depressive symptoms were difficulties with basic ADLs (OR 2.8, 95% CI 1.1.7.8), risk for social isolation (OR 4.1, 95% CI 1.8-9.3), and basic education only (OR 2.2, 95% CI 1.1-4.4). CONCLUSION: Older people experiencing pain are also likely to experience depression. Among those experiencing pain, social network and functional status seem to be more important predictors of depressive symptoms than the severity of pain. Further studies should evaluate whether improvement of social network and functional status might reduce depressive symptoms in older patients.

Subclinical thyroid dysfunction and functional capacity among elderly

Background: Subclinical thyroid dysfunction is common among older people and has been associated with decreased functional capacity but with conflicting data. The aim of this study was to assess the association between subclinical thyroid dysfunction and functional capacity in an elderly population. Methods: We included 5182 participants with a mean age of 75.2 years from the Prospective Study of Pravastatin in the Elderly at Risk (PROSPER). Self-reported functional capacity was assessed using the Barthel Index (BI) and the Instrumental Activities of Daily Living (IADL) scores at baseline and during follow-up. Participants with subclinical hyperthyroidism (n=65) and subclinical hypothyroidism (n=173) were compared to euthyroid participants (n=4944). The association between persistent subclinical thyroid dysfunction and functional capacity and decline was also investigated. Results: At baseline, compared to euthyroid participants (BI 19.73±SE 0.06; IADL 13.52±0.02), there was no difference in functional capacity for participants with subclinical hyperthyroidism (BI 19.60±0.09; IADL 13.51±0.12, p>0.05) or subclinical hypothyroidism (BI 19.82±0.06; IADL 13.55±0.08, p>0.05). Over a mean 3.2-year follow-up period, there was no association between thyroid function and annual decline of either BI or IADL (p>0.05). No association was found between persistent subclinical thyroid dysfunction and functional capacity at baseline or during follow-up (p>0.05). Results were similar after excluding participants with a maximum BI and/or IADL score at baseline. Conclusion: Among well-functioning community-dwelling elderly, we found no evidence that subclinical thyroid dysfunction contributes to decreased functional capacity.

More severe functional impairment in dementia with Lewy bodies than Alzheimer disease is related to extrapyramidal motor dysfunction.

OBJECTIVE The objective of this study was to compare functional impairments in dementia with Lewy bodies (DLB) and Alzheimer disease (AD) and their relationship with motor and neuropsychiatric symptoms. METHODS The authors conducted a cross-sectional study of 84 patients with DLB or AD in a secondary care setting. Patients were diagnosed according to published criteria for DLB and AD. The Bristol Activities of Daily Living Scale (BADLS) was used to assess functional impairments. Participants were also assessed using the Unified Parkinson's Disease Rating Scale (motor section), the Neuropsychiatric Inventory, and the Mini-Mental Status Examination. RESULTS Patients with DLB were more functionally impaired and had more motor and neuropsychiatric difficulties than patients with AD with similar cognitive scores. In both AD and DLB, there were correlations between total BADLS scores and motor and neuropsychiatric deficits. There was more impairment in the mobility and self-care components of the BADLS in DLB than in AD, and in DLB, these were highly correlated with UPDRS score. In AD, orientation and instrumental BADLS components were most affected. CONCLUSION The nature of functional disability differs between AD and DLB with additional impairments in mobility and self-care in DLB being mainly attributable to extrapyramidal motor symptoms. Consideration of these is important in assessment and management. Activities of daily living scales for use in this population should attribute the extent to which functional disabilities are related to cognitive, psychiatric, or motor dysfunction.

Neurostimulation for Parkinson's disease with early motor complications.

BACKGROUND Subthalamic stimulation reduces motor disability and improves quality of life in patients with advanced Parkinson's disease who have severe levodopa-induced motor complications. We hypothesized that neurostimulation would be beneficial at an earlier stage of Parkinson's disease. METHODS In this 2-year trial, we randomly assigned 251 patients with Parkinson's disease and early motor complications (mean age, 52 years; mean duration of disease, 7.5 years) to undergo neurostimulation plus medical therapy or medical therapy alone. The primary end point was quality of life, as assessed with the use of the Parkinson's Disease Questionnaire (PDQ-39) summary index (with scores ranging from 0 to 100 and higher scores indicating worse function). Major secondary outcomes included parkinsonian motor disability, activities of daily living, levodopa-induced motor complications (as assessed with the use of the Unified Parkinson's Disease Rating Scale, parts III, II, and IV, respectively), and time with good mobility and no dyskinesia. RESULTS For the primary outcome of quality of life, the mean score for the neurostimulation group improved by 7.8 points, and that for the medical-therapy group worsened by 0.2 points (between-group difference in mean change from baseline to 2 years, 8.0 points; P=0.002). Neurostimulation was superior to medical therapy with respect to motor disability (P<0.001), activities of daily living (P<0.001), levodopa-induced motor complications (P<0.001), and time with good mobility and no dyskinesia (P=0.01). Serious adverse events occurred in 54.8% of the patients in the neurostimulation group and in 44.1% of those in the medical-therapy group. Serious adverse events related to surgical implantation or the neurostimulation device occurred in 17.7% of patients. An expert panel confirmed that medical therapy was consistent with practice guidelines for 96.8% of the patients in the neurostimulation group and for 94.5% of those in the medical-therapy group. CONCLUSIONS Subthalamic stimulation was superior to medical therapy in patients with Parkinson's disease and early motor complications.

Sleepwalking, REM sleep behaviour disorder and overlap parasomnia in patients with Parkinson's disease

BACKGROUND/AIMS In a questionnaire survey, we identified 36 (9%) of 417 Parkinson's disease (PD) patients with sleepwalking (SW); 72% of them also had a history of REM sleep behaviour disorder (RBD). We aimed to assess the clinical and polysomnographic characteristics of SW in PD and to compare them to patients with PD with and without a history of RBD. METHODS We performed video-polysomnography and detailed clinical examination in 30 PD patients from the above-mentioned survey: 10 patients with a history of SW, 10 patients with a history of RBD, and 10 patients with no history of either SW or RBD. RESULTS PD patients with SW had higher depression, anxiety and Hoehn & Yahr scores and lower activities of daily living scores than patients without a history of RBD but did not differ from patients with RBD. Patients with SW and RBD also had more often dyskinesia and hallucinations. By polysomnography, RBD was observed in 8 patients with SW and in all patients with a history of RBD. A total of 5 patients without a history of either SW or RBD had REM sleep without atonia without behavioural peculiarities. CONCLUSION SW in PD is associated with depression, higher disease severity and functional disability. The simultaneous occurrence of SW and RBD (overlap parasomnia) in most patients suggests a common underlying disturbance of motor control during sleep in PD, with variable manifestations in different sleep stages.
