Is plasma matrix metalloproteinase-9 level better than serum matrix metalloproteinase-9 level to predict gastric cancer evolution?
Our results suggest plasma MMP-9 level is a better marker than serum MMP-9 level for predicting gastric cancer development and progression.
The studied population had a high incidence of obstructive sleep apnea. OSA was more severe in patients offered vertical laryngectomy than in the individuals submitted to horizontal laryngectomy. Spirometry seems to be useful in the detection of cases of suspected OSA, as it suggests the presence of extrathoracic upper airway obstruction.
