The landscape of work engagement in brain injury rehabilitation /

This study examined work engagement among brain injury rehabilitation professionals with specific attention to how they engage with their work (the extent to which they experience vigor, dedication, and absorption while working) and how they engage with people (the degree to which they are welcoming towards others and demonstrate integrity, responsibility, transparency). This study also tested a theoretical model of work engagement that predicted a relationship between engagement and personal, interpersonal, and organizational capacity. Eighty-one staff employed in a hospital-based brain injury program participated in the study. A quantitative self-report survey was used to measure participants' levels of capacity and engagement and a qualitative question was included to identify initiatives that could be introduced to enhance job performance. As predicted by the model, there were statistically significant positive correlations among all three capacity variables and engagement with work and statistically significant positive correlations between ethical engagement and personal and interpersonal capacity. The results of the qualitative data analysis revealed three broad categories of recommendations for improving job performance (more learning opportunities, more resources to support professional development, and the need to build greater team cohesion). These findings provide initial support for a theoretical model that emphasizes the link between capacity and engagement, which could be used to guide theory-driven interventions aimed at improving the work environment.

Health-related quality of life among patients attending cardiovascular rehabilitation

Purpose: f i rst , an investigation of baseline differences in Health-Related Quality of l i fe (HRQOl) among adhere and non-adhere patients of Phase III cardiac rehabilitation (CR) was examined. Second, among patients who adhered to the program, effectiveness of t reatment based on HRQOl was evaluated. Methods: Data was collected by the Brock University Heart Institute. Participants completed a questionnaire battery at baseline and again at six months i f they were still a client. Results: The physical dimension of HRQOl differed at baseline between the adhere and non-adhere groups. for everyone point increase in physical HRQOl scores there was an associated 1.06 times greater likelihood that an individual would adhere to the program. Second, in those who adhered to the program for six months, physical HRQOl scores improved 3.18 points. Conclusions: Phase III CR significant improves HRQOl in patients suffering f rom cardiovascular disease.

THE PREVALENCE AND PREDICTION OF PULMONARY FIBROSIS IN AN

This thesis describes an ancillary project to the Early Diagnosis of Mesothelioma and Lung Cancer in Prior Asbestos Workers study and was conducted to determine the effects of asbestos exposure, pulmonary function and cigarette smoking in the prediction of pulmonary fibrosis. 613 workers who were occupationally exposed to asbestos for an average of 25.9 (SD=14.69) years were sampled from Sarnia, Ontario. A structured questionnaire was administered during a face-to-face interview along with a low-dose computed tomography (LDCT) of the thorax. Of them, 65 workers (10.7%, 95%CI 8.12—12.24) had LDCT-detected pulmonary fibrosis. The model predicting fibrosis included the variables age, smoking (dichotomized), post FVC % splines and post- FEV1% splines. This model had a receiver operator characteristic area under the curve of 0.738. The calibration of the model was evaluated with R statistical program and the bootstrap optimism-corrected calibration slope was 0.692. Thus, our model demonstrated moderate predictive performance.

Self-Esteem and Mastery in Maintenance Cardiac Rehabilitation

Background: CVD is the second leading cause of death in Canada. Mastery and self-esteem are psychosocial factors, suggested to be emerging risk factors for CVD. Purpose: The purpose of the study was two-fold; first to establish whether mastery and self-esteem predicted adherence to maintenance CR; and second, whether mastery and self-esteem improved after a 6-month maintenance CR program. Methods: Data were collected at the Brock University Heart Institute. The study involved a sample of 98 participants. At intake to the program and 6-month follow-up, participants completed a questionnaire battery which included the Rosenberg Self-Esteem Scale and the Pearlin-Schooler Mastery Scale. Results: Mastery and self-esteem scores did not alter the likelihood of adherence to the CR program. Mastery and self-esteem did significantly improve after 6-months of CR amongst participants with the lowest exercise capacity. Conclusion: Maintenance CR does improve mastery and self-esteem amongst those with diminished exercise capacity.

Socio-demographic factors, smoking, symptoms, morbidities and pulmonary function and quality of life in individuals with a heavy smoking history

Objective: To determine which socio-demographic, exposure, morbidity and symptom variables are associated with health-related quality of life among former and current heavy smokers. Methods: Cross sectional data from 2537 participants were studied. All participants were at ≥2% risk of developing lung cancer within 6 years. Linear and logistic regression models utilizing a multivariable fractional polynomial selection process identified variables associated with health-related quality of life, measured by the EQ-5D. Results: Upstream and downstream associations between smoking cessation and higher health-related quality of life were evident. Significant upstream associations, such as education level and current working status and were explained by the addition of morbidities and symptoms to regression models. Having arthritis, decreased forced expiratory volume in one second, fatigue, poor appetite or dyspnea were most highly and commonly associated with decreased HRQoL. Discussion: Upstream factors such as educational attainment, employment status and smoking cessation should be targeted to prevent decreased health-related quality of life. Practitioners should focus treatment on downstream factors, especially symptoms, to improve health-related quality of life.

Effect of respiratory muscle training on pulmonary function in preoperative preparation of tobacco smokers

OBJETIVO: Avaliar o efeito da utilização de um programa de treinamento específico dos músculos respiratórios sobre a função pulmonar em indivíduos tabagistas. MÉTODOS: Foram estudados 50 indivíduos tabagistas assintomáticos com idade superior a 30 anos, nos seguintes momentos: A0 - avaliação inicial seguida do protocolo de exercícios respiratórios; A1 - reavaliação após 10 minutos da aplicação do protocolo; e A2 -reavaliação final após duas semanas de treinamento utilizando o mesmo protocolo três vezes por semana. A avaliação foi realizada através das medidas de pressões respiratórias máximas (PImax. e PEmax.), picos de fluxo respiratórios (PFI e PFE), ventilação voluntária máxima (VVM), capacidade vital Forçada (CVF) e Volume expiratório forçado no primeiro segundo (VEF1). RESULTADOS: Não houve melhora na CVF e VEF1 da avaliação inicial para a final. Houve aumento significativo das variáveis PFI, PFE, VVM e PImax nas avaliações A1 e A2. A variável PEmax. aumentou somente na avaliação A2. CONCLUSÃO: A aplicação de protocolo de exercícios respiratórios com e sem carga adicional em indivíduos tabagistas produziu melhora imediata na performance dos músculos respiratórios, mas esta melhora foi mais acentuada após duas semanas de exercício.

Fatores associados à diferença clinicamente significativa da qualidade de vida relacionada à saúde após condicionamento físico em pacientes com DPOC

OBJETIVO: Investigar os fatores associados à diferença clinicamente significativa da qualidade de vida (DCSQV) após condicionamento físico em pacientes com DPOC. MÉTODOS: Trinta e cinco pacientes foram submetidos a 12 semanas de condicionamento físico, envolvendo treinamento de força e exercício aeróbio leve. Composição corporal, teste incremental e de endurance em esteira, teste de caminhada de seis minutos, força muscular periférica, PImáx, baseline dyspnea index (BDI) e Saint George's Respiratory Questionnaire (SGRQ) foram avaliados antes e após o treinamento, e suas alterações (Δ) foram calculadas. A DCSQV foi definida como a redução > 4% no escore total do SGRQ. Os pacientes que responderam ao treinamento, apresentando DCSQV, foram alocados no grupo respondedores (R; n = 24), e os demais pacientes foram alocados no grupo não-respondedores (NR; n = 11). RESULTADOS: Os seguintes resultados foram significativamente maiores no grupo R que no grupo NR (p < 0,05): VEF1 (1,48 ± 0,54 L vs. 1,04 ± 0,34 L), VEF1/CVF (47,9 ± 11,7% vs. 35,5 ± 10,7%), PaO2 (74,1 ± 9,7 mmHg vs. 65,0 ± 8,9mmHg) e ΔBDI [mediana (interquartil); 2,0 (0,0-3,5) vs. 0,0 (0,0-1,0)]. Houve correlação significativa (p < 0,01) de ΔSGRQ-sintomas (r = 0,44), ΔSGRQ-atividade (r = 0,62) e ΔSGRQ-total (r = 0,60) com ΔBDI. Após regressão logística, apenas ΔBDI foi selecionado como determinante da DCSQV. CONCLUSÕES: A DCSQV após o condicionamento físico está associada principalmente à redução da dispneia nos pacientes com DPOC. Portanto, são necessárias estratégias de tratamento visando interromper o ciclo dispneia-sedentarismo-dispneia nesses pacientes.

L-carnitine as an ergogenic aid for patients with chronic obstructive pulmonary disease submitted to whole-body and respiratory muscle training programs

The effects of adding L-carnitine to a whole-body and respiratory training program were determined in moderate-to-severe chronic obstructive pulmonary disease (COPD) patients. Sixteen COPD patients (66 ± 7 years) were randomly assigned to L-carnitine (CG) or placebo group (PG) that received either L-carnitine or saline solution (2 g/day, orally) for 6 weeks (forced expiratory volume on first second was 38 ± 16 and 36 ± 12%, respectively). Both groups participated in three weekly 30-min treadmill and threshold inspiratory muscle training sessions, with 3 sets of 10 loaded inspirations (40%) at maximal inspiratory pressure. Nutritional status, exercise tolerance on a treadmill and six-minute walking test, blood lactate, heart rate, blood pressure, and respiratory muscle strength were determined as baseline and on day 42. Maximal capacity in the incremental exercise test was significantly improved in both groups (P < 0.05). Blood lactate, blood pressure, oxygen saturation, and heart rate at identical exercise levels were lower in CG after training (P < 0.05). Inspiratory muscle strength and walking test tolerance were significantly improved in both groups, but the gains of CG were significantly higher than those of PG (40 ± 14 vs 14 ± 5 cmH2O, and 87 ± 30 vs 34 ± 29 m, respectively; P < 0.05). Blood lactate concentration was significantly lower in CG than in PG (1.6 ± 0.7 vs 2.3 ± 0.7 mM, P < 0.05). The present data suggest that carnitine can improve exercise tolerance and inspiratory muscle strength in COPD patients, as well as reduce lactate production.

The flower workshop in psychosocial rehabilitation: A pilot study

We report a pilot study with the Flower Workshop, a new modality of psychosocial rehabilitation group activity. Cognitive performance in schizophrenia and other mental conditions can be impaired depending on the tasks to be executed and their respective social context. The vulnerability of these individuals can be reduced by means of cognitive and socio-affective facilitation. We conducted a pilot study to introduce the Flower Workshop in a public Mental Health Service in the city of Ribeirao Preto (Sao Paulo-Brasil) with 12 participants during 18 months (2002-2003). With cognitive and socio-affective facilitation, participants were able to construct vases and make flower arrangements successfully.

Use of algorithms for semi-automatic quantification of pulmonary fibrosis and emphysema

Obtaining a semi-automatic quantification of pathologies found in the lung, through images of high resolution computed tomography (HRCT), is of great importance to aid in medical diagnosis. Paraccocidioidomycosis (PCM) is a systemic disease that affects the lung and even after effective treatment leaves sequels such as pulmonary fibrosis and emphysema. It is very important to the area of tropical diseases that the lung injury be quantified more accurately. In this stud, we propose the development of algorithms in computational environment Matlab® able to objectively quantify lung diseases such as fibrosis and emphysema. The program consists in selecting the region of interest (ROI), and through the use of density masks and filters, obtaining the lesion area quantification in relation to the healthy area of the lung. The proposed method was tested on 15 exams of HRCT of patients with confirmed PCM. To prove the validity and effectiveness of the method, we used a virtual phantom, also developed in this research. © 2013 Springer-Verlag.

Effect of a multimodal exercise program on sleep disturbances and instrumental activities of daily living performance on Parkinson's and Alzheimer's disease patients

Aim: To assess the contribution of a multimodal exercise program on the sleep disturbances (SD) and on the performance of instrumental activities daily living (IADL) in patients with clinical diagnosis of Alzheimer's disease (AD) and Parkinson's disease patients (PD). Methods: A total of 42 consecutive patients (23 training group, 19 control group) with PD and 35 demented patients with AD (19 trained group, 16 control group) were recruited. Participants in both training groups carried out three 1-h sessions per week of a multimodal exercise program for 6 months. The Pfeffer Questionnaire for Instrumental Activities and the Mini-Sleep Questionnaire were used to assess the effects of the program on IADL and SD respectively. Results: Two-way ancova showed interactions in IADL and SD. Significant improvements were observed for these variables in both intervention groups, and maintenance or worsening was observed in control groups. The analysis of effect size showed these improvements. Conclusion: The present study results show that a mild to moderate intensity of multimodal physical exercises carried out on a regular basis over 6 months can contribute to reducing IADL deficits and attenuating SD. © 2013 Japan Geriatrics Society.
