Randomized Controlled Trial Comparative Study Observational StudyInfluence of face mask design on bag-valve-mask ventilation performance: a randomized simulation study.
Different face mask designs can influence bag-valve-mask (BVM) ventilation performance during resuscitation. We compared a single-use, air-cushioned face mask (AM) with a reusable silicone face mask (SM) for quality of BVM ventilation on a manikin simulating cardiac arrest. ⋯ The AM seems to be a more efficient face mask than the SM at delivering sufficient ventilation volumes. The performance of the AM did not seem to be associated with the physical characteristics of the rescuers, whereas that of the SM was affected by these factors. The SM may not be an appropriate face mask for performing one-person BVM ventilation during resuscitation for rescuers who are smaller in stature, have a smaller hand size, or have weaker grip power.

Serum markers of collagen synthesis and degradation in acute respiratory failure patients.
Procollagen-derived propeptides reflect the rate of collagen synthesis and type I cross-linked collagen telopeptides (ICTP) collagen I degradation. We studied the collagen metabolism to find out if changes seen in acute respiratory distress syndrome patients are observed in patients with acute respiratory failure (ARF), and whether multiple organ dysfunction (MOD) has impact on it. ⋯ The collagen metabolism was altered in ARF patients. The first week was dominated by degradation of type I collagen and production of type III collagen, but by day 21, the collagen composition returned to more stable form.

Sleep disturbances and changes in urinary 6-sulphatoxymelatonin levels in patients with breast cancer undergoing lumpectomy.
Sleep disturbances and changes in self-reported discomfort and melatonin secretion are common in the post-operative period. We aimed to study the distribution of sleep stages in the perioperative period and evaluate changes in secretion of the melatonin metabolite aMT6s and subjective parameters of sleepiness, pain, general well-being and fatigue in patients undergoing surgery for breast cancer. ⋯ Patients with breast cancer undergoing lumpectomy had significantly disturbed sleep architecture the night after surgery, and these changes were normalised after 2 weeks.
