Comparative Study
Very prolonged stay in the intensive care unit after cardiac operations: early results and late survival.
Prolonged intensive care unit (ICU) stay is a surrogate for advanced morbidity or perioperative complications, and resource utilization may become an issue. It is our policy to continue full life support in the ICU, even for patients with a seemingly grim outlook. We examined the effect of duration of ICU stay on early outcomes and late survival. ⋯ Current technology enables keeping sick patients alive for extended periods of time. Nearly two thirds of patients requiring prolonged ICU leave hospital, and of these, 50% attain 5-year survival. These data support offering full and continued support even for patients requiring very prolonged ICU stay.

Comparative Study
Association of gender and lowest hematocrit on cardiopulmonary bypass with acute kidney injury and operative mortality in patients undergoing cardiac surgery.
Nadir hematocrit on cardiopulmonary bypass (CPB) is a known risk factor for worse outcomes after cardiac surgery. Whether women, because of lower nadir hematocrit on CPB, are more prone to worse outcomes than men after cardiac surgery remains unknown. ⋯ Both men and women undergoing cardiac surgery on CPB were prone to the deleterious effects of hemodilution on renal function and death. Yet, despite greater hemodilution, women had a lower relative risk of AKI and death than men at lower nadir hematocrit values on CPB suggesting better tolerance to hemodilution in women.

Comparative Study
A propensity-matched comparison of pleurodesis or tunneled pleural catheter in patients undergoing diagnostic thoracoscopy for malignancy.
Patients with a suspected malignant pleural effusion occasionally require thoracoscopy to achieve a diagnosis. It is unclear whether chemical pleurodesis or the placement of a tunneled pleural catheter (TPC) that can be used for intermittent pleural drainage produces superior palliation, a shorter hospital stay, and less morbidity. This investigation compares these 2 treatment groups. ⋯ This investigation found that a TPC provided palliation of patients' malignant pleural effusions and freedom from reintervention equal to that of talc pleurodesis after thoracoscopy while resulting in a shorter mean length of hospital stay and interval to the initiation of systemic therapy. Lower rates of operative morbidity were also seen in the TPC treatment group. This method of palliation of a malignant pleural effusion should be considered when diagnostic thoracoscopy reveals a malignant pleural effusion.

According to the 2007 American Thoracic Society/Infectious Diseases Society of America statement on nontuberculous mycobacterial diseases, more evidence for the benefits of adjuvant nontuberculous mycobacterial lung disease surgical intervention is needed before its wide application can be recommended. ⋯ Pulmonary resection combined with chemotherapy is safe, with favorable treatment outcomes, for patients with localized nontuberculous mycobacterial lung disease. Our results support the liberal use of operations for nontuberculous mycobacterial lung disease whenever indicated.

Comparative Study
Dilatation of the remaining aorta after aortic valve or aortic root replacement in patients with bicuspid aortic valve: a 5-year follow-up.
The natural history and management of ascending aorta (AA) and arch dilatation in patients with bicuspid aortic valve (BAV) after aortic valve replacement (AVR) or aortic root replacement (ARR) remains controversial. Our aim is to identify dilatation of the remaining aorta after AVR or ARR in patients with BAV compared with patients with tricuspid aortic valve (TAV). ⋯ No significant dilatation of the AA or arch was observed after AVR or ARR, respectively, in patients when a cut-off diameter of 4.5 cm or greater was considered for replacement in patients with BAV compared with patients with TAV up to 5 years after operation. The need for aortic replacement at smaller diameters was not found.
