Chronic obstructive pulmonary disease (COPD) is a common chronic inflammatory disease of the lung with a high mortality and morbidity rate. Some of the inflammatory markers such as C-reactive protein (CRP), leukocyte count are associated with COPD. In this study, we aimed to evaluate the role of neutrophil-to-lymphocyte ratio (NLR) in COPD patients comparing with the other well-known inflammatory markers. We retrospectively enrolled the laboratory results of 269 COPD patients of which 178 patients at stable period and 91 patients during acute exacerbation and 50 sex- and age- matched healthy controls. We found that NLR values of the stable COPD patients were significantly higher than those of the controls (P < 0.001). During acute exacerbation of the disease there was a further increase compared to stable period (P < 0.001). NLR values were also positively correlated with serum CRP levels and red cell distribution width (RDW) and negatively correlated with mean platelet volume (MPV) in both COPD groups. In conclusion, NLR could be considered as a new inflammatory marker for assessment of inflammation in COPD patients with its quick, cheap, easily measurable property with routine complete blood count analysis.

This study indicates that pulmonary rehabilitation can prevent loss of muscle strength in ICU. Nevertheless, we consider that further studies with larger populations are needed to examine the impact of NMES and/or active and passive muscle training in bedridden ICU patients who are mechanically ventilated.

BACKGROUND:Invasive procedures such as bronchoscopic biopsy, bronchial washing, and bronchial brushing are widely used in diagnosis of lung cancers. The mean diagnostic rate with bronchoscopic forceps biopsy is 74% in central tumors. This study was designed to evaluate the efficacy of cryobiopsies in histopathological diagnosis.METHODS:Forty-one patients who had interventional bronchoscopy were included in this study. Three forceps biopsies and one cryobiopsy with cryorecanalization probe were obtained from each subject. Biopsies interpretations were done by one expert pathologist.RESULTS:Hemorrhage was the only complication in both procedures. There was no significant difference between these two procedures in the incidence of hemorrhage (P > 0.05). Mean diameters of samples taken with forceps biopsy and cryoprobe biopsy were 0.2 and 0.8 cm, respectively (P < 0.001). Thirty-two patients (78%) were diagnosed with forceps biopsies, and 38 patients (92.7%) were diagnosed with cryoprobe biopsies (P = 0.031).CONCLUSIONS:We concluded that cryoprobe biopsies were more successful than forceps biopsies in diagnosis. Nevertheless, further investigations are warranted to determine an efficacy of cryoprobe biopsy procedures and a rationale to use as a part of routine flexible bronchoscopy.

The BQ is a poor predictor of obstructive sleep apnea (OSA) in subjects admitted to our sleep clinic. BQ and ESS together may be used to detect patients with low risk for OSA.

Platelet indices, MPV and PDW, can be used for the determination of disease severity, and lead to therapeutic strategies for PE patients.
