Qualidade subjetiva do sono e queixa de insônia em pacientes com Acidente Vascular Cerebral

Brain injury can be associated with changes in the sleep-wake cycle. However, studies about sleep disturbances and their relationship with quality of sleep are scarce. Besides, it remains to be known how stroke affects the mechanisms of sleep. The aim of this study was to investigate quality of sleep, complaints of sleep disturbances and associated factors in stroke patients from the Physical Therapy services in Natal -RN. This was a cross-sectional descriptive study involving 70 individuals (aged 45-65 years), 40 patients (57 ± 7 years), 11 ± 9 months after injury, and 30 healthy individua ls (52 ± 6 years), evaluated with the Pittsburgh Sleep Quality Index (PSQI) and Sleep Habits Questionnaire. The data were analyzed by Chi-square test, t Student test and logistic regression. Poor quality sleep was found in 57,5% of the patients (6,3 ± 3,5) and was significantly higher than in the control population (3,9 ± 2,2) (t Student test, p=0,002). The patients showed significantly higher value of PSQI than controls: sleep latency (p=0,019), length of sleep (p=0,039) and dysfunction during the day (p=0,001). Regarding complaints of sleep disturbances (dyssomnias and parasomnias) analyzed by Chi-square test, the complaint of insomnia was the most prevalent (patients: 37,5%; healthy subjects: 6,7%; p=0,007). Regression analysis showed that sl eep latency (p=0,036) and complaint of insomnia (p=0,036) were associated with quality sleep. In addition, female gender (p=0,036) and complaint of broken sleep (p=0,003) were considered risk factors for the presence of insomnia. Our results show that stroke affects the homeostatic process of sleep. Shorter sleep latency and the absence of insomnia are considered protective factors for good sleep quality and this should be taken into consideration in the diagnostic and therapeutic strategies

Proposta de Intervenção para Auxiliar a Reabilitação Motora e Cognitiva de Pacientes com Acidente Vascular Cerebral

Stroke is the leading cause of combined motor and cognitive disability worldwide. The rehabilitation of stroke patients is mostly directed towards motor recovery through the training of the affected member under supervision of a Physical Therapist. In the present study we introduce a new approach for both cognitive and motor therapy, which relies on motor imagery of the upper limbs and working memory training. This therapy should be utilized as an adjuvant to physical therapy. Ten individuals (5 men and 5 women) were selected for the pilot study, all of them in the acute phase of the first ischemic stroke episode. The control group had 5 individuals who were submitted to physical therapy only, whilst the other 5 patients in the experimental group also performed the cognitive and motor training with a video game specially built for this study. Two patients left the experimental group before the end. Total training lasted for 9 weeks, 2 times a week, for half an hour. Patients reported they enjoyed playing the game, even though it required a lot of mental effort, according to them. Plus, they considered it had a beneficial influence in their activities of daily living. No side effects were reported. Preliminary results suggest there is a difference between groups in cognitive and upper limb motor evaluation following the intervention. It is important to notice that our conclusions are limited due the small sample number. Overall, this work is supported by other studies in literature focused in rehabilitation with motor imagery and working memory and indicate a continuity of the research, increasing total training hours

Saúde do trabalhador: entre os dispositivos legais e as práticas efetivas

The health worker is seized in this research beyond the mere applicability of legal devices concerning the legislation of Labor, in order to be established correlations with activities alluding to the public power in the ambit of State of Rio Grande do Norte (RN). This dissertation is an cutting of analysis circumscribed in the research, "Accidents at work: law, citizenship and justice," of the Grupo de Estudos Seguridade Social e Trabalho (GESTO) of Universidade Federal do Rio Grande do Norte (UFRN). The overall goal turned to apprehend and relate contradictory elements inherent compliance of Occupational Health and Safety (OHS) in the supermarket which showed the highest occurrence of legal violations recognized by the Labor Justice of RN in the period between 2006 and 2008 . The specific objectives turned to identify, from the condemnatory sentences, violations inherent in the protective direction of the OH & S legislation; analyze the relationship of health damages to workers at the supposed recognition of rights claimed in condemnatory sentences and correlate violations inherent in the legislation OSH impacts on the health of workers, from data contained in expert reports. The justification for perform the research backed up, among other factors, in the fact that class of activity has been presented as the most recurrent in condemnatory sentences, since it chose to focus the analysis on documentary evidence from the supermarket which showed greater expression in relation to violations of the OSH legislation. From a qualitative perspective, the methodological approach was based on content analysis of thirteen condemnatory sentences, handed down by the potiguar labor justice, and three expert reports from a large supermarket in the city of Natal/RN. Aftermaths are evidenced relating to the cyclical processes of reorganization of capital, demanding requirements for labor organizations whose strategies for survival include identifying mechanisms to extract as much of the work force. Structural determination and ideological context that puts into question the historical achievements of workers, for example the legal devices aimed at preventing workplace accidents, expressed in this research as relativized, showing limitations of reach, as was inferred the indemnities, by material and moral damages, arising from Work-Related Musculoskeletal Diseases (MSDs'S), recognized by the laborite judiciary

Paralelização em GPU da segmentação vascular com extração de Centerlines por Height Ridges

The vascular segmentation is important in diagnosing vascular diseases like stroke and is hampered by noise in the image and very thin vessels that can pass unnoticed. One way to accomplish the segmentation is extracting the centerline of the vessel with height ridges, which uses the intensity as features for segmentation. This process can take from seconds to minutes, depending on the current technology employed. In order to accelerate the segmentation method proposed by Aylward [Aylward & Bullitt 2002] we have adapted it to run in parallel using CUDA architecture. The performance of the segmentation method running on GPU is compared to both the same method running on CPU and the original Aylward s method running also in CPU. The improvemente of the new method over the original one is twofold: the starting point for the segmentation process is not a single point in the blood vessel but a volume, thereby making it easier for the user to segment a region of interest, and; the overall gain method was 873 times faster running on GPU and 150 times more fast running on the CPU than the original CPU in Aylward

BMMobile: uma linha de produtos para dimensionamento de bombeio mecânico em dispositivos móveis

With the increase of processing ability, storage and several kinds of communication existing such as Bluetooth, infrared, wireless networks, etc.., mobile devices are no longer only devices with specific function and have become tools with various functionalities. In the business field, the benefits that these kinds of devices can offer are considerable, because the portability allows tasks that previously could only be performed within the work environment, can be performed anywhere. In the context of oil exploration companies, mobile applications allow quick actions could be taken by petroleum engineers and technicians, using their mobile devices to avoid potential catastrophes like an unexpected stop or break of important equipment. In general, the configuration of equipment for oil extraction is performed on the work environment using computer systems in desktop platforms. After the obtained configuration, an employee goes to equipment to be configured and perform the modifications obtained on the use desktop system. This management process equipment for oil extraction takes long time and does not guarantee the maintenance in time to avoid problems. With the use of mobile devices, management and maintenance of equipment for oil extraction can be performed in a more agile time once it enables the engineer or technician oil can perform this configuration at the time and place where the request comes for example, near in the oil well where the equipment is located. The wide variety of mobile devices creates a big difficulty in developing mobile applications, since for one application can function in several types of devices, the application must be changed for each specific type of device, which makes the development quite costly. This paper defines and implements a software product line for designing sucker-rod pumping systems on mobile devices. This product line of software, called BMMobile, aims to produce products that are capable of performing calculations to determine the possible configurations for the equipment in the design suckerrod pumping, and managing the variabilities of the various products that can be generated. Besides, this work performs two evaluations. The first evaluation will verify the consistency of the products produced by the software product line. The second evaluation will verify the reuse of some products generated by SPL developed

Desenvolvimento, implementação e testes de um sistema de comunicação sem fio heterogêneo para acesso à serviços: aplicações na telemedicina e domótica

Nos últimos de 20 anos, economia e tecnologia evoluíram em muitas direções e em novas áreas. Muitas dessas evoluções criaram oportunidades que estão sendo consideradas na concepção de futuras redes de comunicação. Estas novas possibilidades estão relacionadas à, sobretudo, utilização da internet para o acesso à serviços e englobam: mobilidade; tecnologias de baixo custo; crescimento e empregos (pela Internet participa-se de cada processo de negócios e produção); serviços; educação (oportunidade para as pessoas crescerem e se desenvolverem); entretenimento (mundos virtuais para o lazer, compras e jogos); volume de tráfego maior (texto, voz, imagens, vídeo). Como uma consequência, a Internet se tornou, semelhante a eletricidade ou água, um bem público. Com quase 2 bilhões de usuários (aproximadamente 28% da população mundial), a Internet está se tornando, cada vez mais, uma infraestrutura difusivo oferecendo em qualquer lugar, a qualquer momento conectividade e serviços. Este mundo da Internet atual é o resultado de sucessivas alterações que aconteceram desde o seu surgimento e que tornaram a infraestrutura de comunicação de importância crítica. Em termos de tecnologias de comunicação, os sistemas móveis sem fio têm um lugar especial devido a sua difusão excepcional na última década e que, junto com a Internet, tem permitido o aparecimento de dispositivos inteligentes, a introdução de novos serviços inovadores e exigindo, para tanto, um ambiente que suporte a inovação e criatividade. Porém, os vários padrões de redes para suporte, principalmente, ao acesso de última milha são desvantagens na perspectiva do usuário, pois este tem de se habilitar nessas redes (contratar os serviços) e, não raro, ter terminais específicos para o acesso. A idéia de um padrão único para estas redes não obteve resultados satisfatórios e uma solução aponta para a integração dessas redes para prover acesso único e transparente ao usuário. Esse trabalho, portanto, apresenta uma solução embarcada para integrar padrões de comunicações sem fio heterogênea do tipo IEEE 802.15.4 ZigBee, IEEE 802.20 GSM/GPRS e IEEE 802.2 Wi-Fi. Essa heterogeneidade de tecnologias sem fio permite a um usuário em movimento, através de seu terminal local ou remoto, acessar aplicativos e serviços de forma transparente. A avaliação de desempenho da solução foi realizada utilizando-se dois tipos de serviços: domótica e telemedicina. Os resultados indicaram que a solução proposta consegue integrar e prover os serviços com segurança e confiabilidade.

Efeitos da exposição à sílica sobre a responsividade vascular e de vias aéreas de ratos

Silicosis, a common type of pneumoconiosis, is an occupational lung disease caused by inhalation of silica dust often with mining activity and thus reaches the miners. The fine and ultrafine silica particles deposited in the alveolar epithelium may lead to the development of progressive massive fibrosis. An increased reactive oxygen species (ROS) production has been proposed to explain the mechanism for induction of pulmonary fibrosis in silicosis. In this situation, alveolar macrophages are activated to phagocytes silica particles deposited in the alveoli. The activated macrophages secrete large amounts of ROS that in turn induce synthesis of fibrotic factors. In addition, the activity of antioxidant enzymes is impaired, which results in increased lipid peroxidation, as well as generating a local inflammatory process. Diffuse pulmonary fibrosis progresses with interstitial collagen deposition. Interstitial collagen overlies small pulmonary arteries and arterioles and thus it is associated with pulmonary hypertension in pulmonary fibrotic diseases. In addition, cytokines and silica particles passing through the respiratory membrane can reach the bloodstream. In this context, the increase in the generation of ROS in the circulation may lead to a reduction in the bioavailability of nitric oxide, an important endothelium-derived relaxing factor. A deficiency in the nitric oxide bioavailability can result in vascular endothelial dysfunction. Moreover, pro-inflammatory cytokines could contribute to the impairment of endothelial function. In the airways, pro-inflammatory cytokines can reduce the smooth muscle responsiveness to β- adrenergic agonists as isoproterenol. Thus, the aim of this study was to evaluate the effect of silica dust instillation in the function of the pulmonary artery, aorta and trachea of rats with acute silicosis. For this purpose, male Wistar rats were anesthetized... (Complete abstract click electronic access below)
