Fatores de risco em indivíduos com hipertensão arterial

Este trabalho teve o objetivo de verificar os hábitos relacionados aos fatores de risco em uma população de portadores de hipertensão arterial. A amostra foi composta por 70 indivíduos, constatando-se que a maioria não faz exercício, não tem atividade de lazer, havendo necessidade de programas educativos para aquisição destes hábitos .Há lacunas de informação, pois os clientes têm como ponto de referência, em sua maioria, a própria experiência, ao invés das orientações que recebem de vários profissionais.

Abundant brachiopods on a tropical, upwelling-influenced shelf (Southeast Brazilian Bight, South Atlantic)

Rhynchonelliform brachiopods were diverse and often dominant benthos of tropical seas in the Paleozoic. In contrast, they are believed to be rare in open habitats of modern oceans, especially at low latitudes. This study documents numerous occurrences of rhynchonelliform brachiopods on a modern tropical shelf, particularly in areas influenced by upwelling. Extensive sampling of the outer shelf and coastal bays of the Southeast Brazilian Bight revealed dense populations of terebratulid brachiopods (>10(3) individuals /m(2) of seafloor) between 24 and 26 S. on the outer shelf, brachiopods are more abundant than bivalves and gastropods combined. However, brachiopod diversity is low: only four species belonging to the genera Bouchardia, Terebratulina, Argyrotheca, and Platidia were identified among over 16000 examined specimens. Brachiopods occur preferentially on carbonate bottoms and include two substrate-related associations: Bouchardia (40-70% CaCO3, weight content) and Terebratulina-Argyrotheca (70-95% CaCO3). All four species display a broad bathymetric range that contrasts with a narrow depth tolerance postulated for many Paleozoic rhynchonelliforms. The most abundant populations occur in the depth range between 100 and 200 m, and coincide with zones of shelf-break upwelling, where relatively colder and nutrient-rich water masses of the South Atlantic Central Water are brought upward by cyclonic meanders of the South Brazil Current (a western boundary current that flows poleward along the coast of Brazil). This is consistent with previous biological and paleontological studies that suggest upwelling may play a role in sustaining brachiopod-dominated benthic associations. The presence of abundant brachiopods in the open habitats of the tropical shelf of the western South Atlantic contrasts with current understanding of their latitudinal distribution and points to major gaps in our knowledge of their present-day biogeography. The ecological importance of rhynchonelliform brachiopods in modern oceans and their role as producers of biogenic sedimentary particles may be underestimated.

Revendo os códigos hamming e CRC para tratar com erros na transmissão de dados

This article has the purpose to review the main codes used to detect and correct errors in data communication specifically in the computer's network. The Hamming's code and the Ciclic Redundancy Code (CRC) are presented as the focus of this article as well as CRC hardware implementation. Each code is reviewed in details in order to fill the gaps in the literature and to make it accessible to the computer science and engineering students as well as to anyone who may be interested in learning the technique to treat error in data communication.

Caracterização de programas de intervenção com crianças e/ou adolescentes

The objective was to present a descriptive analysis of interventions to prevent and/or reduce children's and/or adolescents' problem behaviors. The study reviewed 192 abstracts from journal articles published between the 1986 and June 2006, available on the following databases: Index-Psi/Periódicos, Lilacs, PsycInfo, Scielo and Medline. Categories of analysis focused on bibliography, method, and studies' results. Data-analysis showed that most of the studies focused on groups and families, and samples with more than 30 participants. Study designs were experimental and quasi-experimental, combining observation and self report or just self report for data collection. Result analysis suggests that the intervention programs contributed specially for reducing behavior problems, and improving parental practices. Discussion evaluates contributions of the study and gaps in knowledge.

Atitudes distintas de profssionais de diferentes especialidades médicas relacionadas à autonomia e aspectos jurídicos no cuidado de pacientes com demência

The evaluation of competence of Alzheimer's disease (AD) patients to assume personal or collective responsibilities and the resulting legal implications is a relevant issue. Objectives: The aim of this study was to evaluate the attitudes of different medical specialists towards the disability of patients with Alzheimer's disease and practitioners' competence to interfere with decision-making autonomy. Methods: Professionals from different areas (Neurology, Psychiatry, Geriatrics, and General Practice) were interviewed by one of the authors, after being presented a fictitious clinical case which raised several topics, namely: [1] Critical judgment and capacity of the patient to take decisions related to daily activities; [2] The role of family physicians in nominating trustees and caregivers. Results: Answers to the first question did not differ regarding degree of preservation of awareness but at least 25% stressed that the patient must be carefully listened to, independent of caregiver or legal representative opinion. There were significant knowledge gaps in responses to the second question. Half of the physicians interviewed did not have adequate information about the legal aspects of caring for patients with Alzheimer's disease. Conclusions: Legal aspects is a topic that must be incorporated into professional training in order to improve attitudes toward the long-term management of patients with dementia.
