Promoção de intervenções não-farmacológicas para tratar hipertensão arterial
In the first part of this review, definition, prevalence, historical evolution and general principles of nonpharmacologic treatment of hypertesion are discussed. Then, rational basis and behavioural strategies to relieve reduction of obesity, ingestion of salt or alcohol, sedentarism, emotional stress and smoking are presented. Finally, the role of other dietary factors and combined therapy is considered, specially the integration of these therapies in a multidisciplinary approache to the patient with high blood pressure.Na primeira parte desta revisão, discutem-se a definição, prevalência, evolução histórica e os princípios gerais do tratamento não-farmacológico da hipertensão arterial. Em seguida, apresenta-se a base principal e as estratégias comportamentais para redução da obesidade, da ingestão de sal e de bebidas alcoólicas, do sedentarismo, do estresse emocional, e do uso do fumo. Na parte final, discute-se o papel de outros fatores dietéticos, (das terapias combinadas e, particularmente, como elas podem ser integradas em uma abordagem multidisciplinar do paciente hipertenso
Selecting information in electronic health records for knowledge acquisition
AbstractKnowledge acquisition of relations between biomedical entities is critical for many automated biomedical applications, including pharmacovigilance and decision support. Automated acquisition of statistical associations from biomedical and clinical documents has shown some promise. However, acquisition of clinically meaningful relations (i.e. specific associations) remains challenging because textual information is noisy and co-occurrence does not typically determine specific relations. In this work, we focus on acquisition of two types of relations from clinical reports: disease-manifestation related symptom (MRS) and drug-adverse drug event (ADE), and explore the use of filtering by sections of the reports to improve performance. Evaluation indicated that applying the filters improved recall (disease-MRS: from 0.85 to 0.90; drug-ADE: from 0.43 to 0.75) and precision (disease-MRS: from 0.82 to 0.92; drug-ADE: from 0.16 to 0.31). This preliminary study demonstrates that selecting information in narrative electronic reports based on the sections improves the detection of disease-MRS and drug-ADE types of relations. Further investigation of complementary methods, such as more sophisticated statistical methods, more complex temporal models and use of information from other knowledge sources, is needed
High energy from space
The following subject areas are covered: (1) important scientific problems for high energy astrophysics (stellar activity, the interstellar medium in galaxies, supernovae and endpoints of stellar evolution, nucleosynthesis, relativistic plasmas and matter under extreme conditions, nature of gamma-bursts, identification of black holes, active nuclei, accretion physics, large-scale structures, intracluster medium, nature of dark matter, and the X- and gamma-ray background); (2) the existing experimental programs (Advanced X-Ray Astrophysics Facility (AXAF), Gamma Ray Observatory (GRO), X-Ray Timing Explorer (XTE), High Energy Transient Experiment (HETE), U.S. participation in foreign missions, and attached Shuttle and Space Station Freedom payloads); (3) major missions for the 1990's; (4) a new program of moderate missions; (5) new opportunities for small missions; (6) technology development issues; and (7) policy issues
