Randomized Controlled Trial Multicenter Study
Endothelial Permeability and Hemostasis in Septic Shock: Results from the ProCESS Trial.
We studied patients from the Protocolized Care in Early Septic Shock (ProCESS) trial to determine the effects of alternative resuscitation strategies on circulating markers of endothelial cell permeability and hemostasis and the association between biomarkers and mortality. ⋯ We found no relationship between different resuscitation strategies and biomarker profiles in sepsis, but we did find that elevated levels of endothelial cell biomarkers of permeability and hemostasis were associated with increased mortality.

Lung transplantation has evolved into a life-saving treatment with improved quality of life for patients with end-stage respiratory failure unresponsive to other medical or surgical interventions. With improving survival rates, the number of lung transplant recipients with preexisting and posttransplant comorbidities that require attention continues to increase. ⋯ The goals of this partnership include timely referral and assistance with transplant evaluation, optimization of comorbidities and preparation for transplantation, management of common posttransplant medical comorbidities, immunization, screening for malignancy, and counseling for a healthy lifestyle to maximize the likelihood of a good outcome. We aim to provide an outline of the main aspects of the care of candidates for and recipients of lung transplants for nontransplant physicians and other care providers.

The interaction between obesity and OSA is complex. Although it is often assumed that obesity is the major cause of OSA, and that treatment of the OSA might mitigate further weight gain, new evidence is emerging that suggests this may not be the case. Obesity explains about 60% of the variance of the apnea-hypopnea index (AHI) definition of OSA, mainly in those < 50 years and less so in the elderly. ⋯ The slight fall in the overall AHI with weight loss, however, may be associated with a larger drop in the nonsupine AHI, thus converting some patients from nonpositional to positional (ie, supine only) OSA. Importantly, patients undergoing surgical weight loss need close monitoring to prevent complications. Finally, in patients with moderate to severe obesity-related OSA, the combination of weight loss with CPAP appears more beneficial than either treatment in isolation.
