Optimizing care in the ICU is an important goal. The heightened severity of illness in patients who are critically ill combined with the tremendous costs of critical care make the ICU an ideal target for improvement in outcomes and efficiency. Incorporation of evidence-based medicine into everyday practice is one method to optimize care; however, intensivists have struggled to define optimal practices because clinical trials in the ICU have yielded conflicting results. This article reviews examples where such conflicts have occurred and explores possible causes of these discrepant data as well as strategies to better use critical care clinical trials in the future.

CASP7 plays a crucial role in cancer development and chemotherapy efficacy. We, therefore, explored whether single nucleotide polymorphisms (SNPs) of the CASP7 gene can modulate outcomes of patients with advanced non-small cell lung cancer (NSCLC) treated with first-line platinum-based chemotherapy. ⋯ This study provides evidence that genetic variations of CASP7 may modulate OS and PFS of patients with advanced NSCLC treated with platinum-based chemotherapy.

Case Reports
IgG4-related systemic disease presenting with lung entrapment and constrictive pericarditis.
We describe a 29-year-old woman who presented with chronic pleuropericarditis complicated by lung entrapment and constrictive pericarditis. Pleural biopsy performed during the decortication procedure revealed fibrinous pleuritis with lymphoplasmacytic inflammation including IgG4-positive plasma cells. The patient responded favorably to corticosteroid therapy with resolution of pleural effusion and constrictive physiology. To our knowledge, this is the first reported case of IgG4-related systemic disease manifesting as lung entrapment and constrictive pericarditis.

Mycobacterial spindle cell pseudotumor (MSP) is a rare benign lesion characterized by local proliferation of spindle-shaped histiocytes containing acid-fast mycobacteria. Most reported cases of MSP occur in the lymph nodes, skin, spleen, and brain in patients who are immunocompromised, particularly following solid organ transplant and in those with AIDS. This is a case report of a patient with AIDS who presented with cough, generalized weakness, and fatigue, who was found to have multilobar lung masses that were MSP, which to our knowledge has not yet been reported in the literature.
