A produção do cuidado a usuários com hipertensão arterial e as tecnologias em saúde

Objetivou-se com este trabalho analisar a utilização da tecnologia das relações na produção do cuidado a usuários com hipertensão arterial. Trata-se de estudo qualitativo, realizado em oito Unidades de Saúde da Família de Jequié-BA. Os sujeitos do estudo foram formuladores da política, profissionais de saúde e usuários, totalizando dezesseis informantes. Em 2010, realizou-se entrevista semiestruturada, observação sistemática e análise documental. Para apreciação dos dados utilizou-se análise de conteúdo temática. Os resultados evidenciaram que os profissionais, sobretudo enfermeiros e agentes comunitários de saúde, utilizam tecnologias leves na busca da integralidade. Por outro lado, alguns profissionais demonstraram prática biologicista, com ênfase em normas e procedimentos. Conclui-se que há necessidade de mudança na interação entre trabalhador e usuário, considerando-se a singularidade e a autonomia do usuário e família na construção de novas formas de cuidado.

Enfermeiros de Unidade de Terapia Intensiva adulto: avaliação sobre medida direta e indireta da pressão arterial

Estudo descritivo e de corte transversal que teve como objetivo avaliar e autoavaliar o conhecimento de enfermeiros de Unidades de Terapia Intensiva adulto sobre medida direta e indireta da pressão arterial. Foram abordados 54 enfermeiros de três Unidades de Terapia Intensiva. Foi aplicado um questionário auto respondido com 65 questões (40 relacionadas à pressão arterial). Os enfermeiros apresentaram desempenho insuficiente no teste que avaliou conhecimento (nota média 4,6). Metade da amostra sentiu-se pouco satisfeita com relação ao que sabe sobre pressão arterial. Após responder o questionário os sujeitos autoavaliaram seu conhecimento como regular (48,2%), ruim (27,8%) e péssimo (9,3%), manifestando estarem conscientes em relação à importância do assunto para a prática. Os resultados do estudo mostram a necessidade de realização urgente de atividades de educação continuada para esta amostra, visto que são profissionais que atuam diretamente com um sinal vital prioritário no cuidado ao paciente crítico.

Volume of Traffic on the Primary Road System, 2002

The Office of Transportation Data, in cooperation with the Federal Highway Administration, prepares this biennial traffic report. This report is used by federal, state, and local governmental agencies in determining highway needs, construction priorities, route location and environmental impact studies, and the application of appropriate design standards. The general public uses this information in determining the amount of traffic that passes a given area as they make their development plans and propose land use changes. The above reflects only a few of the many technical uses for this data.

Content validation of the dimensions constituting non-adherence to treatment of arterial hypertension

The objective of the study was to validate the content of the dimensions that constituted nonadherence to treatment of arterial systemic hypertension. It was a methodological study of content validation. Initially an integrative review was conducted that demonstrated four dimensions of nonadherence: person, disease/treatment, health service, and environment. Definitions of these dimensions were evaluated by 17 professionals, who were specialists in the area, including: nurses, pharmacists and physicians. The Content Validity Index was calculated for each dimension (IVCi) and the set of the dimensions (IVCt), and the binomial test was conducted. The results permitted the validation of the dimensions with an IVCt of 0.88, demonstrating reasonable systematic comprehension of the phenomena of nonadherence.

Partial gene deletion of endothelial nitric oxide synthase predisposes to exaggerated high-fat diet-induced insulin resistance and arterial hypertension.

Nitric oxide (NO) plays a major role in the regulation of cardiovascular and metabolic homeostasis, as evidenced by insulin resistance and arterial hypertension in endothelial NO synthase (eNOS) null mice. Extrapolation of these findings to humans is difficult, however, because eNOS gene deficiency has not been reported. eNOS gene polymorphism and impaired NO synthesis, however, have been reported in several cardiovascular disease states and could predispose to insulin resistance. High-fat diet induces insulin resistance and arterial hypertension in normal mice. To test whether partial eNOS deficiency facilitates the development of insulin resistance and arterial hypertension during metabolic stress, we examined effects of an 8-week high-fat diet on insulin sensitivity (euglycemic clamp) and arterial pressure in eNOS(+/-) mice. When fed a normal diet, these mice had normal insulin sensitivity and were normotensive. When fed a high-fat diet, however, eNOS(+/-) mice developed exaggerated arterial hypertension and had fasting hyperinsulinemia and a 35% lower insulin-stimulated glucose utilization than control mice. The partial deletion of the eNOS gene does not alter insulin sensitivity or blood pressure in mice. When challenged with nutritional stress, however, partial eNOS deficiency facilitates the development of insulin resistance and arterial hypertension, providing further evidence for the importance of this gene in linking metabolic and cardiovascular disease.

The effects of arterial flow on platelet activation, thrombus growth, and stabilization.

Injury of an arterial vessel wall acutely triggers a multifaceted process of thrombus formation, which is dictated by the high-shear flow conditions in the artery. In this overview, we describe how the classical concept of arterial thrombus formation and vascular occlusion, driven by platelet activation and fibrin formation, can be extended and fine-tuned. This has become possible because of recent insight into the mechanisms of: (i) platelet-vessel wall and platelet-platelet communication, (ii) autocrine platelet activation, and (iii) platelet-coagulation interactions, in relation to blood flow dynamics. We list over 40 studies with genetically modified mice showing a role of platelet and plasma proteins in the control of thrombus stability after vascular injury. These include multiple platelet adhesive receptors and other junctional molecules, components of the ADP receptor signalling cascade to integrin activation, proteins controlling platelet shape, and autocrine activation processes, as well as multiple plasma proteins binding to platelets and proteins of the intrinsic coagulation cascade. Regulatory roles herein of the endothelium and other blood cells are recapitulated as well. Patient studies support the contribution of platelet- and coagulation activation in the regulation of thrombus stability. Analysis of the factors determining flow-dependent thrombus stabilization and embolus formation in mice will help to understand the regulation of this process in human arterial disease.

Une cause exceptionnelle d'hypertension artérielle de l'enfant : l'artérite de Takayasu [An exceptional cause of arterial hypertension in children: Takayasu arteritis].

Takayasu arteritis, a nonspecific inflammatory arteritis, is particularly rare in children. We report the case of a 6-year-old girl presenting with severe arterial hypertension in the upper segment associated with an inflammatory syndrome. Investigations showed coarctation of the abdominal aorta at different levels, due to Takayasu arteritis. The patient was treated with percutaneous dilatation and stent implantation as well as prolonged anti-inflammatory therapy. Arterial hypertension in children needs to be investigated until its cause, which may be rare such as Takaysu arteritis, is determined.

Arterial hypertension and associated factors in patients submitted to myocardial revascularization

OBJECTIVE To identify the prevalence of arterial hypertension and associated factors in patients submitted to myocardial revascularization. METHOD Cross-sectional study using the database of a hospital in São Paulo (SP, Brazil) containing 3010 patients with coronary artery disease submitted to myocardial revascularization. A multiple logistic regression was performed to identify variables independently associated with hypertension (statistical significance: p<0.05). RESULTS Prevalence of hypertension was 82.8%. After the variables were adjusted, the associated factors were as follows: age, odds ratio (OR): OR=1.01; 95% confidence interval (CI): CI:1.00-1.02; female gender: (OR=1.77;CI:1.39-2.25); brown-skin race: (OR=1.53;CI:1.07-2.19); obesity: (OR=1.53;CI:1.13-2.06); diabetes: (OR=1.90;CI:1.52-2.39); dyslipidemia: (OR=1.51;CI:1.23-1.85); and creatinine>1.3: (OR=1.37;CI:1.09-1.72). CONCLUSION A high prevalence of arterial hypertension and association with both non-modifiable and modifiable factors was observed.
