Abstract: pulmonary hypertension occurs when the pressure of the pulmonary artery is disproportionally high for a certain level of pulmonary blood flow. values of mean pulmonary artery pressure of more than 25 mm hg at rest or 30 mm hg during exercise allow the diagnosis of pulmonary hypertension. sustained or chronic pulmonary hypertension may be secondary to known diseases, mainly to those of cardiac or pulmonary nature, or may be a primary abnormality of the pulmonary circulation, with or without identification of associated conditions. advances in the knowledge of the mechanisms of vasoconstriction and vascular remodeling have brought better prospects for the treatment of the disease. the correct use of vasodilators and anticoagulants, the new vasodilators, as epoprostenol and its analogs, and surgical techniques have increased the survival of many patients. pneumologists can view cases of pulmonary hypertension as complications of pulmonary diseases or as a result of dyspnea investigation. despite its etiology, pulmonary hypertension represents a clear abnormality that affects the right ventricle and can be potentially fatal to patients. image methods have made the diagnosis of pulmonary hypertension more accessible and non-invasive. six cases of patients with pulmonary hypertension of different causes are presented and discussed. in conclusion, according to new concepts, idiopathic pulmonary hypertension is no longer an irreversible condition, and the identification of associated conditions with potential treatments can be favorable in the management of the patients with pulmonary hypertension.

Abstract: the goal of this work was to present the three theories that defend the monopoly and oligopoly deregulation: demsetz critic, theory of contestable markets and theory of capture. this was achieved using bibliographic and internet research. we support the debate concerning this economical aspect, in brazil and other countries, alerting about problems, costs and difficulties related to the regulation and also studying some industrial cases where the deregulation has already taken place. we concluded that much reflection is necessary when dealing with industrial regulation since there are less damaging options from the point of view of competition - and therefore more pro-consumers. the regulation, defended as a protection against abusive (monopolist) prices, among other problems may become a way of monopoly perpetuation; it could set prices and taxes in high levels, by collusion between regulated and regulators; it is expensive, difficult to execute and to monitor. the deregulation, despite its importance, is relatively not much debated, even though it could be a politic to be implemented in several situations.

Abstract: OBJETIVO: Este estudo objetivou avaliar o desfecho de pacientes com cancer de pulm o admitidos na unidade de terapia intensiva e verificar o perfil clínico e demográfico deles. MéTODOS: Estudo analítico observacional, retrospectivo, em que foi avaliado o desfecho de pacientes com diagnóstico de cancer de pulm o que internaram na unidade de terapia intensiva de um hospital universitário de janeiro de 2010 até fevereiro de 2011. RESULTADOS: Foram incluídos 34 prontuários de pacientes. Vinte e seis (76,5%) receberam algum tipo de suporte ventilatório, 21 (61,8%) utilizaram ventila o mecanica invasiva e 11 (32,4%) utilizaram ventila o n o invasiva em algum momento durante a estadia na unidade de terapia intensiva. Considerando a letalidade, 12 (35,3%) foram a óbito durante o período de interna o na unidade de terapia intensiva, totalizando 15 (44,1%) óbitos durante todo o período de hospitaliza o; 19 (55,9%) pacientes obtiveram alta do hospital para casa. A análise das variáveis mostrou que os pacientes que foram a óbito permaneceram um período maior em ventila o mecanica invasiva 5,0 (0,25-15,0) dias do que os sobreviventes (1,0 (0-1,0) dias) (p=0,033) e realizaram diálise durante a estadia na unidade de terapia intensiva (p=0,014). CONCLUS ES: A mortalidade dos pacientes com cancer de pulm o admitidos em unidade de terapia intensiva está associada com o tempo de permanência na ventila o mecanica invasiva e a necessidade de diálise. OBJECTIVE: This study aimed to evaluate the outcomes for patients with lung cancer admitted to intensive care units and assess their clinical and demographic profiles. METHODS: Retrospective, analytical, observational study, wherein the outcomes for patients diagnosed with lung cancer admitted to the intensive care unit of university hospital from January 2010 until February 2011 were evaluated. RESULTS: Thirty-four patients' medical records were included. Twenty-six (76.5%) patients received some type of ventilatory support, of whom 21 (61.8%) used invasive mechanical ventilation and 11 (32.4%) used noninvasive ventilation at some point during their stay at the intensive care unit. Regarding mortality, 12 (35.3%) patients died during hospitalization at the intensive care unit, totaling 15 (44.1%) deaths during the entire hospitalization period; 19 (55.9%) patients were discharged from the hospital. The analysis of the variables showed that the patients who died had remained on invasive mechanical ventilation for a longer period 5.0 (0.25 to 15.0) days than the survivors (1.0 (0 to 1.0) days) (p=0.033) and underwent dialy

Abstract: The consumer’s demand for healthier products along with issues such as salinization, soil affections and successive planting and cropping foment the pursuit for more sustainable production systems that the ones in practice currently. To such an extent, the present study aimed to evaluate the nutrition of plants due to electrical conductivity of nutrient using different substrates. The experiment was conducted at the Agrarian Sciences Center at UEL. For the cultivation was used UEL-2 bean pod type, which has determined growth, average height of 40 cm, straight pods with flat section and harvest around 55 days after planting. The experiment outline was randomized blocks with subdivided plots. The plots were composed by treatments holding nutrient solutions with electrical conductivity of: 0.5, 1.0, 1.5 and 2.0 mS cm-1 and subdivisions composed by substrates consisting of: carbonized rice hulls, Pinus bark and a combination of 50% carbonized rice hulls + 50% pine bark. A total of 60 pots of 5 liters each were used, each one holding two plants that were watered twice a day, with the aid of manual watering, containing 150 ml of variable nutrient solution, depending on each of the treatments electrical conductivity. The levels of fresh and dry matter of roots, stems, leaves and pods, pod length and diameter, electrical conductivity and pH’s of eluviated ones were analyzed throughout the whole cycle. The obtained results were submitted to analysis of variance and the substrates averages compared by the Tukey test at 5% probability, and the quantities of electrical conductivity by means of regression. The use of nutrient solution with electrical conductivity of 1.5 mS cm-1 and the substrate containing 50% pine bark over 50% carbonized rice hulls resulted in increased productivity, with 182 g pot-1, corresponding to 1.09kg m2. At the same time, the use of carbonized rice hulls substrate with the electrical conductivity of 0.5 mS cm-1 showed the worst results, with production of 47.6 g pot-1, and extrapolated to 0.286 kg m2. The substrate composed by the combination of carbonized rice hulls over pine bark was proved to be more suitable in substrate applications in such cases. Among the treatments tested, the best results were obtained using higher electrical conductivities between 1.5 and 2.0 mS cm-1. A exigência dos consumidores por produtos mais saudáveis, aliada a problemas como saliniza o, doen as de solo e cultivos sucessivos, promovem a busca por sistemas produtivos mais sustentáveis que os atuais. Assim o presente trabalho teve como objetivo a avalia o nu

Abstract: Hipertens o arterial pulmonar (HP) ocorre quando os níveis de press o da artéria pulmonar s o desproporcionalmente elevados para um dado nível de fluxo sanguíneo pulmonar. Valores de press o arterial pulmonar média superiores a 25mmHg em repouso ou 30mmHg em exercício permitem o diagnóstico de HP. A HP sustentada ou cr nica pode ser secundária a doen as conhecidas, principalmente de natureza cardíaca ou pulmonar, ou ser uma anormalidade primária da circula o pulmonar, com ou sem identifica o de condi es associadas. Pneumologistas podem enfrentar casos de HP como conseqüência de pneumopatias ou como achados de investiga es de dispnéia. Independente de sua etiologia, a HP representa uma anormalidade definida que afeta o ventrículo direito e tem conseqüências potencialmente fatais para os pacientes acometidos. Métodos de imagens têm tornado o diagnóstico de HP mais acessível e n o invasivo. Avan os no entendimento dos mecanismos de vasoconstri o e remodelamento vascular têm aberto melhores perspectivas para o tratamento. O uso criterioso de vasodilatadores tradicionais e de anticoagulantes, o surgimento de novos vasodilatadores, como o epoprostenol e seus análogos, e as técnicas cirúrgicas têm melhorado a sobrevida de parcela significativa de pacientes. Seis casos de pacientes com HP, de etiologias variadas, s o apresentados e suas abordagens discutidas. Conclui-se pelo conceito emergente de que a HP idiopática nem sempre é uma condi o irreversível e que a identifica o de condi es associadas potencialmente tratáveis exerce efeito favorável no manejo de pacientes com HP.

Abstract: tuberculosis is a curable disease that can evolve to severe forms, requiring the treatment of the patients in an icu, especially if there is a delay in the diagnosis or if it affects elderly patients, those on dialysis, or those with hiv infection or other states of immunosuppression, as well as in cases of multidrug resistant disease. knowledge of the radiological presentation of the cases can help diagnose these severe forms, as can the introduction of new tests, such as the early detection of the etiological agent by pcr and chest ct, which favors the early initiation of treatment. in addition, the use of regimens without isoniazid and rifampin, as well as uncertain enteral absorption and low serum concentrations of antituberculosis drugs, can reduce the efficacy of treatment. for such patients, the prognosis is generally poor and mortality rates are high.
