The indications for hematopoietic stem cell transplantation (HSCT) continue to expand. However, the risk for pulmonary complications post-HSCT continues to be high. Early recognition and treatment of pulmonary complications may improve outcomes. ⋯ This article will also address pretransplantation evaluation and infectious and noninfectious complications in the patient post-HSCT. While mortality post-HSCT continues to improve, respiratory failure continues to be the leading cause of ICU admissions for patients who have undergone HSCT. Mechanical ventilation is a predictor of poor outcomes in these patients, and further research is needed regarding their critical care management, treatment options for noninfectious pulmonary complications, and mortality prediction models posttransplantation.

Little is known about the comparative validity, reliability, or responsiveness of instruments for assessing cough frequency or impact, where the term impact encompasses both cough severity and the impact of cough on health-related quality of life. ⋯ Electronic recording devices can be valid assessments of cough frequency. The LCQ and CQLQ for adults and the Parent Cough-Specific Quality of Life questionnaire for children are valid instruments for assessing cough impact. There is limited but insufficient evidence to determine the reliability or concurrent validity of the different types of cough diaries or visual analog scale scores. There are also limited data to support the responsiveness of recording devices. There is good responsiveness data for the LCQ and CQLQ, but more evidence is needed.

It is unclear how to appropriately manage discontinuation and resumption of antiplatelet therapy in patients with coronary stents who need noncardiac surgery. We undertook a systematic review of the literature to identify practice guideline statements regarding antiplatelet therapy in patients with coronary stents undergoing noncardiac surgery. ⋯ Most current recommendations are based on expert opinion. This review highlights the need for well-designed prospective studies to identify optimal management strategies in patients with coronary stents who are on antiplatelet therapy and who need noncardiac surgery.

While the canonical function of somatostatin (SST) is to inhibit the secretion of growth hormone, it has a number of other physiologic effects that are less widely appreciated. Octreotide, an analog of SST, is not uncommonly used in the critical care setting, particularly for the treatment of variceal hemorrhage. Herein, we discuss the biology and pharmacology of SST, octreotide, and other SST analogs. We also review the evidence behind their use in esophageal variceal bleeds, hepatorenal syndrome, hypoglycemia due to sulfonylurea poisoning, and chylous pleural effusions.

Randomized Controlled Trial
A randomized controlled trial of balance training during pulmonary rehabilitation for individuals with COPD.
Deficits in balance are increasingly recognized among the important secondary impairments in COPD. The purpose of this study was to investigate the effect of a balance-training program on measures of balance and physical function in patients with COPD enrolled in pulmonary rehabilitation (PR). ⋯ Our results support the feasibility and effectiveness of balance training as part of PR for improving balance performance, muscle strength, and self-reported physical function in patients with moderate to severe COPD.
