13. Envolvimento das pequenas vias aéreas na Síndrome do Desconforto Respiratório Agudo: papel da inflamação, das alterações do surfactante e da apoptose de células epiteliais / Expression of acute phase cytokines, surfactant proteins, and epithelial apoptosis in small airways of human ARDS
Alguns estudos sugerem que as pequenas vias aéreas têm um papel importante na fisiopatologia da lesão pulmonar aguda/ síndrome do desconforto respiratório agudo (LPA/SDRA). O epitélio respiratório que reveste as vias aéreas é capaz de liberar mediadores inflamatórios e está relacionado ainda com a produção de surfactante nas vias aéreas. Até o

14. A scanographic assessment of alveolar recruitment and overinflation during high frequence ventilation : preliminary results in three patients
BACKGROUND AND OBJECTIVES: High-frequency ventilation (HFV) may offer an attractive alternative to conventional strategies in the ventilation of the acute respiratory distress syndrome (ARDS) or acute lung injury (ALI) because it can minimize lung injury. Maintaining ventilation between lower and upper inflection points, it can warrant alveolar recruitment w

15. Análise das capacidades citoadesivas de Plasmodium vivax de pacientes da Amazônia brasileira / Evaluation of cytoadhesive capacities of Plasmodium vivax from Brazilian Amazon patients
Malária vivax foi por muito tempo considerada uma infecção benigna, porém, complicações frequentes nas infecções por P. falciparum, como a malária cerebral, síndrome respiratória aguda (ARDS), disfunção hepática, trombocitopenia grave e baixo peso ao nascer devido à infecção placentária, também têm sido observadas em pacientes infectados

16. Neutrophil apoptosis : a marker of disease severity in sepsis and sepsis-induced acute respiratory distress syndrome
Introduction Apoptosis of neutrophils (polymorphonuclear neutrophils [PMNs]) may limit inflammatory injury in sepsis and acute respiratory distress syndrome (ARDS), but the relationship between the severity of sepsis and extent of PMN apoptosis and the effect of superimposed ARDS is unknown. The objective of this study was to correlate neutrophil apoptosis w

17. Pathological and ultrastructural analysis of surgical lung biopsies in patients with swine-origin influenza type A/H1N1 and acute respiratory failure
BACKGROUND: Cases of H1N1 and other pulmonary infections evolve to acute respiratory failure and death when co-infections or lung injury predominate over the immune response, thus requiring early diagnosis to improve treatment. OBJECTIVE: To perform a detailed histopathological analysis of the open lung biopsy specimens from five patients with ARDS with conf

18. Perfil temporal da inflamação pulmonar induzida pela isquemia/reperfusão intestinal em ratos. Estudo do papel do sistema linfático. / Time profile of lung inflammation induced by intestinal ischemia/reperfusion in rats. Role of the lymphatic system.
A isquemia/reperfusão intestinal (I/R-i) se associa ao desenvolvimento de inflamação pulmonar aguda, que pode ser modulada por mediadores inflamatórios presentes na linfa. Avaliamos os efeitos da I/R-i sob a inflamação pulmonar e a participação do sistema linfático. Wistar machos foram submetidos a 45 min de isquemia intestinal e 24, 72 ou 120 h de

19. Variable positive end-expiratory pressure can maintain oxygenation in experimental acute respiratory distress syndrome induced by oleic acid in dogs
The use of positive end-expiratory pressure (PEEP) or lung recruitment maneuvers (RM) to improve oxygenation in acute respiratory distress syndrome (ARDS) is used but it may reduce cardiac output (CO). Intermittent PEEP may avoid these complications. Our objective was to determine if variable PEEP compared with constant PEEP is capable of maintaining arteria

20. Estudo tomográfico de pressões de colapso alveolar e níveis isogravitacionais em pulmões de pacientes com SDRA e LPA / Tomographic study of alveolar collapsing pressures and isogravitational levels and in the lungs of patients with ARDS and/or ALI
A prospective clinical study performed on 11 patients with ARDS or ALI with the intention of studying the regional behavior of lung tissue density and alveolar collapse along the three spatial axes. An initial recruitment maneuver was followed by multiple semi-complete CT scans at descending levels of PEEP. Multiple linear regression (R2=0.83) showed a gravi

21. Estudo da expressão dos genes regulatórios de hipóxia durante a inflamação pulmonar produzida pela isquemia e reperfusão intestinal em camundongos AIRmax e AIRmin / Study of hypoxia regulatory genes expression during lung inflammation produced by intestinal ischemia-reperfusion in AIRmax and AIRmin mice
Oxygen homeostasis is essential for survival and physiologic development of organisms. Lack of O2 in tissues is a common underlying factor in morbidity and mortality for numerous serious medical conditions such as the Acute Respiratory Distress Syndrome (ARDS). For homeostasis recovery the myeloid cells exert their functions in specialized areas of hypoxia.

22. Effects of pressure controlled ventilation and volume controlled ventilation on pulmonary function in cardiac surgery patients with cardiopulmonary bypass / Efeitos do suporte ventilatorio com pressão controlada e volume controlado na função pulmonar dos pacientes submetidos a cirurgia cardiaca com circulação extra-corporea
Postoperative lung injury after cardiac surgery with cardiopulmonary bypass (CPB) is usually related to the systemic inflammatory response syndrome (SIRS). Many patients undergoing this procedure develop acute lung injury (ALI), and some of them acute respiratory distress syndrome (ARDS). Many factors can be directly or indirectly related to the postoperativ

23. Effects of open lung concept following ARDSNet ventilatory strategy in patients with early acute lung injury (ALI) / acute respiratory distress syndrome (ARDS) / Avaliação de estratégia ventilatória seqüencial em pacientes com lesão pulmonar aguda (LPA) / síndrome do desconforto respiratório agudo (SDRA)
Low tidal volumes are associated with a reduction in mortality in ALI / ARDS. Nevertheless, the application of recruitment maneuvers and high levels of PEEP are still controversial. The aim of this study was to compare the ARDSnet protocol with a strategy based on Open Lung Concept (OLC), applied in a sequential way, in terms of pulmonary function, computed

24. Effects of recruitment maneuver during expiration and inspiration analyzed by thoracic CT scan in patients with acute lung injury and acute respiratory distress syndrome / Efeitos da manobra de recrutamento alveolar nas fases inspiratória e expiratória na tomografia computadorizada de tórax em pacientes com lesão pulmonar aguda ou síndrome do desconforto respiratório agudo
The goal of Maximal Recruitment Strategy (MRS) guided by thoracic CT scan is to minimize alveolar collapse and the mechanisms of ventilator induced lung injury (VILI). The objectives of this study were to compare by quantitative analyzes of CT scan image of the lungs obtained during MRS of patients with ARDS, the following parameters: collapse, overdistensio
