Os médicos brasileiros seguem as diretrizes brasileiras de hipertensão?

OBJETIVO: Avaliar os procedimentos adotados pelos médicos brasileiros para o diagnóstico e tratamento da hipertensão em relação aos preconizados pelas IV Diretrizes Brasileiras de Hipertensão. MÉTODOS: Questionário aplicado por entrevista telefônica a médicos brasileiros, buscando levantar recebimento e adesão às diretrizes, bem como avaliar vários aspectos relacionados ao manejo do paciente hipertenso. RESULTADOS: 68,3% dos médicos receberam às diretrizes e responderam completamente o questionário, perfazendo uma amostra de 483 médicos, sendo 47% cardiologistas, 31,7% clínicos e 21,3% nefrologistas. A adesão a certos pontos das diretrizes é alta, tais como à utilização de mais de uma medida em ocasiões diferentes para o diagnóstico de hipertensão (94,0%) e orientação quanto a mudanças no estilo de vida como estratégia terapêutica. Quanto aos valores utilizados para diagnóstico e alvo-terapêutico, o seguimento as recomendações não é uniforme, com uma nítida preferência por valores inferiores aos preconizados, particularmente para pacientes com co-morbidades. A procura por fatores de risco cardiovascular também se mostrou baixa, com apenas 64,7% e 56,4% dos médicos referindo pesquisar, respectivamente, a presença de diabetes e dislipidemia. Os diuréticos são a classe de droga preferencialmente citada (59,3%) como tratamento medicamentoso inicial da hipertensão. CONCLUSÃO: O seguimento as diretrizes é apenas parcial. Questões como uma melhor distribuição do documento, normatização de valores para diagnóstico e alvo-terapêutico e formas de abordar o paciente hipertenso dentro de seu risco cardiovascular global deverão ser mais bem abordadas quando da confecção de futuras diretrizes.

Energy from waste (EfW): a feasibility study on the economic and the environmental co-benefits of biogas production within rural communities

Energy from waste (E/W) technologies in the form o f biogas plants, CHP plants and other municipal solid waste (MSW) conversion technologies, have been gaining steady ground in the provision o f energy throughout Europe and the UK. Urban Waste Water Treatment Plants (UWWTP) are utilising much o f the same biochemical processes common to these E/W plants. Previous studies on Centralised Anaerobic Digestion (CAD) within Ireland found that the legislative and economic conditions were not conducive to such an operation on the grounds o f low energy price for electric and heat energy, and due to the restrictive nature o f the allowable feedstocks. Recent changes to the Irish REFIT tariff on energy produced from Anaerobic digestion; alterations to the regulation o f the allowable use o f animal by products(ABP); the recent enactment o f the Renewable Energy D irective (09/28/EC) and a subsequent review o f the draft Biowaste Directive (2001) required that the issue o f decentralised energy production in Ireland be reassessed. In this instance the feasibility study is based on a extant rural community, centred around the village o f Woodford Co Galway. The review found that the prevailing conditions were now such that it was technically and economically feasible for this biochemical process to provide energy and waste treatment facilities at the above location. The review also outlines the last item which is preventing this process from becoming achievable, specifically the lack o f a digestate regulation on land spreading which deals specifically with biowaste. The study finds that the implementation o f the draft EU biowaste regulations, with amendments for Cr and Hg levels to match the proposed Irish regulation for compost, would ensure that Ireland has some o f the most restrictive regulations in Europe for this application. The delay in completing this piece o f legislation is preventing national energy and waste issues from being resolved in a planned and stepwise fashion. A proposed lay out for the new Integrated Waste from Energy Plant (IW/EP) is presented. Budget economic projections and alternative revenue streams are outlined. Finally a review o f the national policies regarding the Rural Development Plan (RDP), the Rural Planning Guidelines (RPG) and the National Renewable Energy Action Plan (NREAP) are examined against the relevant EU directives.

Co-administration of Apelin and T4 Protects Inotropic and Chronotropic Changes Occurring in Hypothyroid Rats

AbstractBackground:One of the most important thyroid hormone targets is the cardiovascular system. Hemodynamic changes, such as decreased resting heart rate (HR), myocardial contractility, and cardiac output, and increased diastolic pressure and systemic vascular resistance, have been observed in hypothyroid patients. Moreover, in these patients, ECG changes include sinus bradycardia and low voltage complexes (P waves or QRS complexes).Objective:This study aimed at evaluating the prophylactic effect of apelin on HR changes and QRS voltage that occur in propylthiouracil (PTU)-induced hypothyroid rats.Method:In this study, 48 adult male Wistar rats weighing 170-235g were randomly divided into 6 groups: Control group (normal saline ip injection + tap water gavage); P group (PTU 0.05%, in drinking water); A group (apelin 200 µg.kg-1.day-1, ip); PA group [co-administration of PTU and apelin]; PT group [co-administration of PTU + T4 (0.2 mg/g per day, gavage)]; and PAT group (co-administration of PTU, apelin and T4). All experiments were performed for 28 consecutive days, and then the animals were anesthetized with an ip injection of ketamine (80 mg/kg) and xylazine (12 mg/kg). Lead II electrocardiogram was recorded to calculate HR and QRS voltage.Results:Heart rate and QRS voltage increased more significantly in the hypothyroid group that consumed both apelin and T4 (201 ± 4 beat/min, 0.71 ± 0.02 mv vs. hypothyroid 145 ± 9 beat/min, 0.563 ± 0.015 mv; respectively).Conclusion:The co-administration of apelin and T4 showed a protective effect on QRS voltage and HR in PTU‑induced hypothyroid rats.

Influência do cloro, sôbre a composição do caldo da cana de açúcar Co 290, aplicado no solo, na forma de cloreto de sódio

Considering the economic importance of the sugar industry among ourselves, the authors carried out a field experiment (Latin square) with Co 290 sugar cane, on a white sandy soil of Piracicaba, State of São Paulo, Brazil, applying NaCl in increasing rates (from 6.8 to 54.5 grams per plant), in order to study the effects of chlorides, on productivity and on the composition of juice. No toxic or stimulating effect was found, and there was no change in yield, in degree of purity of the juice, in general aspect of plants or in colour of leaves and culms. No difference was observed between potassium sulphate or chloride, as source of potash for sugar cane culture. Data collected and the literature cited suggest: (a) that the use of the variety Co 290 is indicated for soils rich in chlorine, such as the saline soils of the North-east and Atlantic Coast of Brazil; (b) that it is necessary to extend studies in Research Institutes and Agricultural Experiment Stations of the country to verify the behaviour of other varieties of sugar cane in the types of soils mentioned, especially with respect their yielding capacity. The authors are already planning such investigations.
