This study aimed to review the literature addressing motor physical therapy for intensive care unit adult patients. A literature search was conducted in the databases, PubMed, MedLine (International Literature and Health), LILACS (Latin American and Caribbean Health Sciences) and Cochrane between 1995 and December 2008 using the keywords: physical therapy, mobilization and intensive care unit. For comparison purposes we selected randomized controlled trials and prospective studies, addressing the subject motor physical therapy for intensive care unit adult patients. ⋯ Early mobilization is a new area, with little evidence so far. However, recent studies have confirmed that mechanically ventilated patients mobilization is safe and feasible, reducing both the intensive care unit and hospital stay. However, more studies are warranted to identify the exercise type, duration, intensity and impact for of early motor therapy in specific groups of patients.

To predict readmission in intensive care unit analyzing the first 24 hours data after intensive care unit admission. ⋯ Age, comorbidities and respiratory- and/or sepsis-related admission are associated with increased readmission risk in the studied sample.

Genetic susceptibility in acute lung injury and acute respiratory distress syndrome.
Acute lung injury and its most severe presentation, acute respiratory distress syndrome, are a common denominator for several diseases which can lead to exaggerated lung inflammation. In the last years this variability has been ascribed, at least partially, to genetic issues. This study aims to review the role of the main genes involved in acute lung injury and acute respiratory distress syndrome susceptibility, morbidity and mortality. ⋯ Genetic polymorphisms are gene variations in at least 1% population. These gene variations may influence the inflammatory response mediators' expression, directly affecting the susceptibility to acute lung injury, the intensity of lung parenchyma inflammation, the development clinical course and outcome. Association studies reproducible in large populations will definitely allow genomics to be included into the diagnostic and therapeutic armamentarium for acute lung injury/acute respiratory distress syndrome patients.

Understanding the PIRO concept: from theory to clinical practice - Part 1.
Despite recent advances in diagnosis and care of critically ill patients sepsis related mortality rate remains unacceptably high. Therefore, new methods of evaluation are necessary to provide an earlier and more accurate characterization of septic patients. Based on the (oncologic) TNM system, the PIRO concept was introduced as a new staging system for sepsis in order to assess risk and predict prognosis, with potential to assist in inclusion of patients in clinical studies and estimate the probability of response of patients to specific therapeutic interventions.

Controversies involving hypercapnic acidosis in acute respiratory distress syndrome.
Acute respiratory distress syndrome is characterized by a diffuse inflammatory reaction of lung parenchyma induced by a direct insult to the alveolar epithelium (pulmonary acute respiratory distress syndrome) or an indirect lesion through the vascular endothelium (extrapulmonary acute respiratory distress syndrome). The main therapeutic strategy for acute respiratory distress syndrome is the ventilatory support. However, mechanical ventilation can worsen lung injury. ⋯ Hypercapnic acidosis has been considered by some authors as a modulator of the inflammatory process of acute respiratory distress syndrome. However, clinical and experimental studies on the effects of hypercapnic acidosis have shown controversial results. Therefore it is important to better elucidate the role of hypercapnic acidosis in acute respiratory distress syndrome.
