Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive fibrotic disease limited to the lung, with high variability in the course of disease from one patient to another. Patients with IPF may experience acute respiratory deteriorations; many of these acute declines are idiopathic and are termed acute exacerbations (AE) of IPF. In these cases, the exclusion of alternative causes of rapid deterioration, including heart failure, bilateral pneumonia or pulmonary embolism, is a challenging goal. ⋯ In conclusion, although significant progress in assessing disease severity in IPF has been made, AEs remain unpredictable and are associated with a high risk of death. Improvements in our understanding of the etiology, risk factors, clinical predictors and epidemiology are needed. It is the goal of clinical researchers in the field to provide respiratory physicians with evidence-based guidance to identify patients who may benefit from therapy for preventing or treating AE-IPF.

Body mass index (BMI) is an easily calculated indicator of a patient's body mass including muscle mass and body fat percentage and is used to classify patients as underweight or obese. This study is to determine if BMI extremes are associated with increased 28-day mortality and hospital length of stay (LOS) in emergency department (ED) patients presenting with severe sepsis. We performed a retrospective chart review at an urban, level I trauma center of adults admitted with severe sepsis between 1/2005 and 10/2007, and collected socio-demographic variables, comorbidities, initial and most severe vital signs, laboratory values, and infection sources. ⋯ Neither LOS nor adjusted 28-day mortality was significantly increased or decreased in underweight or obese patients with severe sepsis. Morbidly obese patients may have decreased 28-day mortality, partially due to differences in initial presentation and source of infection. Larger, prospective studies are needed to validate these findings related to BMI extremes in patients with severe sepsis.

Hemostatic abnormalities frequently occur in critically ill patients and may vary from prolonged global clotting tests or isolated thrombocytopenia, to composite defects, such as consumption coagulopathies. There are many reasons for a disturbed coagulation in intensive care patients, and each of these underlying syndromes may require specific therapeutic intervention. Hence, an adequate differential diagnosis and initiation of proper (supportive) therapeutic strategies are critical to decrease morbidity and mortality in critically ill patients with hemostatic abnormalities.
