The utility of neutrophil-to-lymphocyte ratio determined at initial diagnosis in predicting disease stage and discriminating between active and stable disease in patients with sarcoidosis: a cross-sectional study.

Objective: To evaluate the utility of neutrophil-lymphocyte ratio (NLR) determined at initial diagnosis in predicting advanced disease stage and discriminating between active and stable disease in sarcoidosis.

Methods: A total of 465 patients with biopsy-proven sarcoidosis (age: 47 years, 70.5% females) were included in this retrospective cross-sectional study.

Can red blood cell distribution width (RDW) level predict the severity of acute exacerbation of chronic obstructive pulmonary disease (AECOPD)?

Background: Elevated red blood cell distribution width (RDW) levels were associated with mortality in patients with stable chronic obstructive lung pulmonary diseases (COPD). There are limited data about RDW levels in acute exacerbation of COPD (AECOPD).

Aim/objective: The association of the RDW levels with the severity of AECOPD was evaluated according to admission location, (outpatient-clinic, ward and intensive care unit (ICU)).

Hyponatremia prolongs hospital stay and hypernatremia better predicts mortality than hyponatremia in hospitalized patients with community-acquired pneumonia.

Introduction: Dysnatremia is reported to have a prognostic effect in various diseases. A limited number of studies have been published on dysnatremiarelated parameters and clinical outcome in patients with pneumonia. The aim of the study is to analyze the factors related to baseline dysnatremia and to evaluate the clinical outcome of dysnatremia on hospital stay, 30-day and 1-year mortality in hospitalized patients with community-acquired pneumonia (CAP).
