A comparative analysis of errors in inhaler technique among COPD versus asthma patients.

Purpose: This study was designed to evaluate errors in inhaler technique in COPD vs asthma patients and to investigate the association of poor inhaler technique with patient demographics and clinical variables.

Patients And Methods: A total of 509 adult patients with COPD (n=328) or asthma (n=181) who were currently using an inhaler device were included in this study. Data on patient demographics, duration of disease, type and duration of inhaler therapy, and assessment of inhaler technique were recorded.

Neutrophil to lymphocyte ratio is a better indicator of COPD exacerbation severity in neutrophilic endotypes than eosinophilic endotypes.

Background: Complete blood count parameters provide novel inflammatory markers, namely neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR). We aimed to assess any differences in these novel inflammatory markers according to exacerbation severity in patients with COPD in both eosinophilic and neutrophilic endotypes.

Method: This retrospective cross-sectional study was conducted at a tertiary education hospital.

Severity of acidosis affects long-term survival in COPD patients with hypoxemia after intensive care unit discharge.

Background: Patients admitted to the intensive care unit (ICU) with acute respiratory failure (ARF) due to COPD have high mortality and morbidity. Acidosis has several harmful effects on hemodynamics and metabolism, and the current knowledge regarding the relationship between respiratory acidosis severity on the short- and long-term survival of COPD patients is limited. We hypothesized that COPD patients with severe acidosis would have a poorer short- and long-term prognosis compared with COPD patients with mild-to-moderate acidosis.

The impact of exposure to biomass smoke versus cigarette smoke on inflammatory markers and pulmonary function parameters in patients with chronic respiratory failure.

Purpose: The aim of this study was to evaluate the impact of exposure to biomass smoke vs cigarette smoke on serum inflammatory markers and pulmonary function parameters in patients with chronic respiratory failure (CRF).

Patients And Methods: A total of 106 patients with CRF divided into age and gender-matched groups of cigarette-smoke exposure (n=55, mean [SD] age: 71.0 [12.

Does eosinophilia and neutrophil to lymphocyte ratio affect hospital re-admission in cases of COPD exacerbation?

Introduction: We aimed to assess the relationship between peripheral eosinophilia and neutrophil/lymphocyte ratio with hospital admissions and re-admissions with chronic obstructive pulmonary disease (COPD) exacerbations.

Materials And Methods: An observational cohort study was carried out in a tertiary teaching hospital. Subjects with previously diagnosed COPD and who were admitted as outpatients with acute exacerbations were included.

Eosinophilic and non-eosinophilic COPD patients with chronic respiratory failure: neutrophil-to-lymphocyte ratio as an exacerbation marker.

Aim: Increased dyspnea, sputum volume, and purulence are subjective symptoms in COPD patients. To diagnose COPD exacerbations with chronic respiratory failure (CRF) and to assess the requirement for antibiotic treatment, physicians require more objective criteria. We aimed to investigate whether neutrophil-to-lymphocyte ratio (NLR) can be used as an infectious exacerbation marker in COPD patients with CRF.

Analysis of Age Distribution and Disease Presentation of 1269 Patients with Sarcoidosis.

Objective: While the incidence of sarcoidosis peaks between 20 and 39 years, it is comparatively low in elderly subjects. We sought to determine whether there are age-dependent differences in the demographic and laboratory characteristics of patients with sarcoidosis.

Materials And Methods: We retrospectively collected information from our database using the International Classification of Disease (ICD) diagnostic code D86 between 2008 and 2014.

[Lung carcinoma patients aged eighty years over and prognostic factors affecting survival].

Introduction: Almost 50% of all cancers and 70% of cancer deaths occur in cases aged 65 years and more. Thus diagnosis, treatment and follow up in old cases gain importance. Since there a limited number of study that show age-mortality relation in lung cancer cases aged 80 years and over, issues may arise in diagnosis and treatment process of these cases.

Serum Uric Acid Levels and Uric Acid/Creatinine Ratios in Stable Chronic Obstructive Pulmonary Disease (COPD) Patients: Are These Parameters Efficient Predictors of Patients at Risk for Exacerbation and/or Severity of Disease?

BACKGROUND Serum uric acid (sUA) levels were previously found to be correlated with hypoxic states. We aimed to determine the levels of sUA and sUA/creatinine ratios in stable COPD patients and to evaluate whether sUA level and sUA/creatinine ratio can be used as predictors of exacerbation risk and disease severity. MATERIAL AND METHODS This cross-sectional study included stable COPD patients and healthy controls.

Can patients with moderate to severe acute respiratory failure from COPD be treated safely with noninvasive mechanical ventilation on the ward?

Purpose: Noninvasive mechanical ventilation (NIMV) usage outside of intensive care unit is not recommended in patients with COPD for severe acute respiratory failure (ARF). We assessed the factors associated with failure of NIMV in patients with ARF and severe acidosis admitted to the emergency department and followed on respiratory ward.

Patients And Methods: This is a retrospective observational cohort study conducted in a tertiary teaching hospital specialized in chest diseases and thoracic surgery between June 1, 2013 and May 31, 2014.

Patient Outcome after Chronic Obstructive Pulmonary Disease Exacerbations Requiring Non-invasive Ventilation during Hospitalization.

Introduction: Noninvasive ventilation (NIV) during hospitalization for acute hypercapnic exacerbations of chronic obstructive pulmonary disease (COPD) has been shown to be effective, but data on the prognosis of such patients is limited. The aim of this study was to investigate in-hospital and long-term outcome in patients with COPD exacerbations requiring NIV treatment during hospitalization.

Methods: Between 2011 and 2013, hospitalized subjects with hypercapnic COPD exacerbations were included in this retrospective single-center cohort study.

The utility of inflammatory markers to predict readmissions and mortality in COPD cases with or without eosinophilia.

Background: COPD exacerbations requiring hospitalization increase morbidity and mortality. Although most COPD exacerbations are neutrophilic, approximately 10%-25% of exacerbations are eosinophilic.

Aim: We aimed to evaluate mortality and outcomes of eosinophilic and non-eosinophilic COPD exacerbations and identify new biomarkers that predict survival.
