Previous studies that evaluated mortality in elderly subjects who received mechanical ventilation had conflicting results. The aim of this systematic review was to evaluate the effects of age on mortality. ⋯ Although low-quality evidence was available, we conclude that age is associated with a greater mortality in critical subjects who were receiving mechanical ventilation.

Effectiveness of Hammock Positioning in Reducing Pain and Improving Sleep-Wakefulness State in Preterm Infants.
Hammock positioning is now frequently used with preterm infants admitted to ICUs. However, few studies have investigated the extent to which hammock positioning reduces pain and improves the sleep-wakefulness state compared with traditional positioning. ⋯ Hammock positioning was an effective treatment option to reduce pain and improve sleep-wakefulness state. It also helped to reduce heart rate and breathing frequency, and to increase peripheral SpO2 , which made it a treatment option for preterm infants.

In patients with COPD, limited data have been reported concerning the association between dyspnea perception and exercise tests. Moreover, the perception of dyspnea has not been analyzed in patients with the same severity of air-flow obstruction. The aim of our study was to evaluate the relationship between the degree of dyspnea and exercise capacity in subjects with COPD who had the same severity of air-flow obstruction. ⋯ In subjects with COPD and with the same severity of air-flow obstruction, a high score in dyspnea was related to a poor maximum exercise capacity. Our results support the view that, in COPD, the severity of air-flow obstruction was less informative than symptoms in the combined assessment of the disease.
