s: The purpose of this study was to examine the effects of two supportive therapies, conventional mechanical ventilation (CMV) and arteriovenous CO(2) removal (AVCO(2)R), during treatment of severe smoke/burn injury-induced ARDS. ⋯ This in vitro work specifically examines cell death in lung cells as a result of smoke/burn injury and effects of therapeutic interventions. Our in vivo studies temporally correlate the clinical pathology to that studied in these lung cells and show that both in vivo and in vitro cell death is predominantly apoptotic and is significantly reduced by AVCO(2)R.

The clinical practice of lung transplantation (LT) varies widely among transplant centers. The objective of this study was to determine the practice patterns of North American lung transplant programs in specific areas that are considered controversial by most lung transplant practitioners. ⋯ This survey provides a large, time-sensitive database summarizing the clinical practice of LT in North America. In general, the survey responses demonstrated a remarkable degree of consistency around patient selection criteria, but much greater variance in posttransplant management of lung transplant recipients. These findings may reflect the fact that a published selection criteria guideline exists, but no similar documents have been designed for postoperative management. Hopefully, postoperative areas with widely divergent approaches to management will foster future collaborative studies aimed at identifying the most appropriate practices.

Heart rate recovery (HRR) after exercise correlates with decreased vagal tone and mortality. Patients with COPD may have altered autonomic tone. We sought to determine the association of HRR with spirometry measures of pulmonary function. ⋯ Abnormalities found on spirometry are associated with abnormal HRR, which may reflect an altered autonomic tone associated with pulmonary dysfunction, either obstructive or restrictive in nature.

To understand how Medicaid recipients with asthma view their experience with care. ⋯ Asthmatic patients rated the quality of the information that their physicians provide very highly and reported that that they understand how to treat exacerbations. However, they do not take prescribed inhaled steroids on a daily basis. In addition, many asthmatic patients reside in homes where cigarette smoking is present.
