Abstract

During an apnea, hemodynamic complications such as hypoxemia, a rise in systemic and pulmonary arterial pressure, and changes in heart rate occur in patients with obstructive sleep apnea (OSA). Potential mechanisms of OSA-associated renal dysfunction include renal hypoxia, hypertension, endothelial dysfunction. Hypertension is common in patients with OSA. This study aims to assess OSA patients' renal functions and investigate the creatinine clearance (CC) values across OSA patients with and without hypertension. The study included 530 individuals with OSA and 60 individuals with an apnea-hypopnea index (AHI) of 0.05). A statistically significant difference was detected in urea and creatinine levels between the OSA and control groups (p=0.005; p=0.012). Creatinine clearance decreases in patients with OSA in the presence of HT. Patients with OSA often experience cardiovascular disorders, and glomerular endothelial dysfunction occurs in OSA patients.

Abstract

Numerous studies determined that the neutrophil/lymphocyte (NLR) and platelet/lymphocyte ratios (PLR) had prognostic value in several cancer types. This study aimed to evaluate the relationship between NLR and PLR values with the survival time of lung cancer patients. Patients diagnosed with lung cancer between January 2014 and December 2016, were retrospectively evaluated. Demographic characteristics, disease stages, laboratory parameters recorded, and the relationship of NLR and PLR values with the survival time and the disease stage evaluated. NLR and PLR were categorized into two groups. SPSS 17.0 software package was used for the statistical analysis. ROC analysis, Student T-test, Chi-square, and Mann-Whitney U test were used. Mean age of 62±8 years were included in the study. In the NSCLC group, the average NLR and PLR values were 4±3.35 and 194.6±144.4 respectively. Regarding the NSCLC group, the overall survival time was shorter in the subgroup with an NLR >3.43 (13.1 months) compared to the subgroup with an NLR ≤3.43 (24.3 months). The mean survival time was shorter in the group with a PLR > 136.9 compared to the group with a PLR ≤136.9 (15.9 and 24.6 months respectively). Subgroups consisting of survivors and non-survivors in the NSCLC group showed a statistically significant difference considering neutrophil and lymphocyte count, CRP, NLR, and PLR values (p
