To determine granulocyte colony-stimulating factor (G-CSF), epithelial neutrophil-activating peptide (ENA)-78, and interleukin (IL)-8 in BAL fluid (BALF), epithelial lining fluid (ELF), and serum for establishing the concentration gradient of G-CSF, ENA-78, and IL-8 between the blood and the alveolar space in ARDS and acute lung injury (ALI); and to evaluate the relationship of G-CSF, IL-8, and ENA-78 to pulmonary neutrophilia and severity of lung injury. ⋯ G-CSF may be pathophysiologically important for accumulation and activation of neutrophils in ARDS. Local G-CSF production is the likely driving force for neutrophils rather than elevation of circulating levels. In comparison to ENA-78, IL-8 seems to be the predominant neutrophil chemoattractant in the early phase of ARDS.

To determine the effects of hyperchloremic acidosis, induced by dilute HCl infusion, on BP and circulating inflammatory mediators in an experimental model of severe sepsis in the rat. ⋯ Moderate acidosis (SBE of 5 to 10 mEq/L), induced by HCl infusion, worsened BP and increased plasma nitrate/nitrite levels but had no effect on circulating cytokines in septic rats. However, severe acidosis (SBE of 10 to 15 mEq/L), while still causing hypotension, did not affect plasma nitrate/nitrite levels.

Randomized Controlled Trial Clinical Trial
The efficacy of premixed nitrous oxide and oxygen for fiberoptic bronchoscopy in pediatric patients: a randomized, double-blind, controlled study.
s: The aim of the study was to evaluate the efficacy and safety of premixed 50% nitrous oxide and oxygen on the quality of sedation and pain control during fiberoptic bronchoscopy (FB) in children. ⋯ This study demonstrates the improved efficacy of sedation, pain control, and safety of premixed 50% nitrous oxide and oxygen for FB in children.

Randomized Controlled Trial Clinical Trial
A phase I trial of intranasal Moli1901 for cystic fibrosis.
The peptide drug Moli1901 activates an alternative chloride channel that is present in cystic fibrosis (CF) nasal and airway epithelia. Doing so bypasses the dysfunctional CF transmembrane regulator. ⋯ Moli1901 stimulates chloride transport in normal and CF nasal epithelia in vivo, but may have a shorter duration of action in CF participants.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of three wound dressings on infection, healing comfort, and cost in patients with sternotomy wounds: a randomized trial.
To compare three dressing types in terms of their ability to protect against infection and promote healing, patient comfort, and cost-effectiveness. ⋯ In the context of no additional benefit for the prevention of wound infection or the rate of wound healing for any of the three dressing products examined, dry absorbent dressings are the most comfortable and cost-effective products for sternotomy wounds following cardiac surgery.
