High Resource Utilization Does Not Affect Mortality in Acute Respiratory Failure Patients Managed with Tracheostomy.
Tracheostomy practice in patients with acute respiratory failure (ARF) varies greatly among institutions. This variability has the potential to be reflected in the resources expended providing care. In various healthcare environments, increased resource expenditure has been associated with a favorable effect on outcome. ⋯ We were unable to demonstrate a positive relationship between resource expenditure and outcome in ARF patients managed with tracheostomy.

GAS6 IN ARDS PATIENTS: DETERMINATION OF PLASMA LEVELS AND INFLUENCE OF PEEP SETTING.
Growth-arrest-specific protein 6 (GAS6) is a vitamin K-dependent protein expressed by endothelial cells and leukocytes participating in cell survival, migration and proliferation and involved in many pathological situations. The aim of our study was to assess its implication in ARDS and its variation according to PEEP setting, considering that different cyclic stresses could alter GAS6 plasma levels. ⋯ GAS6 plasma level is elevated in ARDS patients. The high-PEEP strategy is associated with a decrease in GAS6 and IL-8 plasma levels at day 3, without significant differences in day 28 mortality between the 2 groups. (Clinicaltrials.gov NCT00188058).

Sampler filling time begins with the initial flash of blood in the needle hub until the preset sampler volume is obtained. Previous studies have shown statistically significant differences between arterial and venous sampler filling times, but included only a few subjects with abnormal blood pressures. ⋯ There is a significant difference between arterial and venous filling rates. There was no relationship between filling time and abnormal mean arterial pressure. Regardless of the arterial pressure, the arterial sampler filling time can be used as an indicator of a successful arterial puncture at the bedside.

To investigate the effects of moderate-intensity exercise on the sympathetic nervous system in male smokers. ⋯ Increased sympathetic nervous system activity, including thermoregulatory activity, might contribute to cachexia in smokers.
