Relationship between functional status and fatigue after COVID-19 infection: a multicenter study from Türkiye.

Background/aim: Symptoms of COVID-19 may persist for months. One of the persistent symptoms of COVID-19 is fatigue, which reduces functional status. The relationship between fatigue, functional status, and various other factors has received little attention, which this study aims to address.

Comparison of BAP65, DECAF, PEARL, and MEWS Scores in Predicting Respiratory Support Need in Hospitalized Exacerbation of Chronic Obstructive Lung Disease Patients.

Objective: Prognostic models aid clinical practice with decision-making on treatment and hospitalization in exacerbation of chronic obstructive lung disease (ECOPD). Although there are many studies with prognostic models, diagnostic accuracy is variable within and between models.

Subjects And Methods: We compared the prognostic performance of the BAP65 score, DECAF score, PEARL score, and modified early warning score (MEWS) in hospitalized patients with ECOPD, to estimate ventilatory support need.

Smoking Cessation Success and Affecting Factors in Geriatric Patients.

Background: There are difficulties in the treatment of smoking cessation in elderly patients. However, elderly smokers who gave up smoking had lower rates of death from heart attack, stroke, and cancer, as well as improved cognitive function. This study aimed to investigate the affecting factors and the success of smoking cessation rate in patients aged 60 and over in Turkey.

Development and validation of a simple risk scoring system for a COVID-19 diagnostic prediction mode.

Materials: Patients who applied to the emergency pandemic clinic between April 2020 and March 2021 were enrolled in this retrospective study.

Impact of posaconazole prophylaxis and antifungal treatment on BAL GM performance in hematology malignancy patients with febrile neutropenia: a real life experience.

Background: Diagnostic accuracy of galactomannan measurements is highly variable depending on the study population, diagnostic procedures, and treatment procedures. We aimed to evaluate the effect of posaconazole prophylaxis and empiric antifungal treatment upon diagnostic accuracy of GM measurements in bronchoalveolar lavage (BAL), bronchial lavage (BL), and serum in hematological malignancy population.

Methods: Patients hospitalized in a single tertiary care center with hematologic malignancies undergoing fiberoptic bronchoscopy (FOB) with a preliminary diagnosis of IPA were retrospectively included.

Lung cancer from suspicion to treatment: An indicator of healthcare access in Turkey.

Background: Lung cancer is the leading cause of cancer-related deaths worldwide. Before beginning lung cancer treatment, it is necessary to complete procedures such as suspecting lung cancer, obtaining a pathologic diagnosis, and staging. This study aimed to investigate the processes from suspicion of lung cancer to diagnosis, staging, and treatment initiation.

Understanding the Impact of Pulmonary Rehabilitation on Airway Resistance in Patients with Severe COPD: A Single-Center Retrospective Study.

Purpose: We investigated the effect of pulmonary rehabilitation (PR) on airway resistance in chronic obstructive pulmonary disease (COPD) patients with severe airway obstruction and hyperinflation.

Patients And Methods: This retrospective cohort study was conducted with data from severe COPD cases with those who underwent an 8-week PR program. Main inclusion criteria were having severe airflow obstruction (defined as a forced expiratory volume in one second (FEV) <50%) and plethysmographic evaluation findings being compatible with hyperinflation supporting the diagnosis of emphysema (presence of hyperinflation defined as functional residual capacity ratio of residual volume to total lung capacity (RV/TLC) >120%).

AVAPS-NIV treatment in hypercapnic respiratory failure with insufficient response to fixed-level PS-NIV.

Introduction: Noninvasive ventilation (NIV) for acute hypercapnic respiratory failure (AHRF) is an established treatment modality. Current evidence does not conclude any superiority between fixed pressure support (PS) and average volume-assured pressure support (AVAPS) modes. However, given the ability of rapid PaCO2 decline in AVAPS mode, we hypothesized that COPD patients with AHRF who did not show the desired reduction in PaCO2 with fixed-level PS-NIV might benefit from the AVAPS mode.

Serum Krebs von den Lungen-6: promising biomarker to differentiate CPFE from IPF.

Background   Combined pulmonary fibrosis and emphysema (CPFE) has been recognised as a phenotype of pulmonary fibrosis. We aimed to compare serum surfactant protein-A (SP-A), surfactant protein-D (SP-D) and Krebs von den Lungen-6 (KL-6) levels, functional parameters, in CPFE and  IPF (idiopathic pulmonary fibrosis) patients. Methods Patients diagnosed with 'CPFE' and 'IPF' were consecutively included in 6 months as two groups.

The Knowledge and Attitude about New Generation Tobacco Products among Physicians.

Objective: Health hazards of e-cigarettes including "e-cigarette or vaping product use-associated lung injury" are better understood today. Just as e-cigarettes, heated tobacco products release toxic emissions. We aimed to determine the knowledge and attitude about new generation tobacco products among physicians who were the members of an organization for health care professionals, the majority of whom are pulmonologists.

Tocilizumab treatment in COVID-19: A prognostic study using propensity score matching.

Background: The potential role of interleukin-6 (IL-6) in coronavirus disease 2019 (COVID-19) pneumonia provides the rationale for investigating IL-6 signaling inhibitors.

Objectives: To evaluate and report treatment responses to tocilizumab (TCZ) in COVID-19 patients and compare mortality outcomes with those of standard care.

Material And Methods: Patients hospitalized with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, diagnosed with reverse transcription polymerase chain reaction (RT-PCR) between March 2020 and April 2021, were enrolled in this single-center retrospective cohort study.

Turkish Thoracic Society's Statement Report on Electronic Cigarettes and Heated Tobacco Products.

Tobacco addiction, which causes the death of more than 8.5 million people in the world every year, is a preventable global public health problem. There are 1.

Association of SARS-CoV-2 cycle threshold (Ct) values with clinical course and serum biomarkers in COVID-19 patients.

Introduction: Our knowledge has gaps regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication levels and its association to severity of Coronavirus disease 2019 (COVID-19). The aim of this study was to investigate the association of SARS-CoV-2 viral load with disease severity and serum biomarkers in COVID-19 patients.

Methodology: Viral load was determined via cycle threshold (Ct) values of SARS-CoV-2 real-time reverse transcriptase-polymerase chain reaction (RT-PCR) in 214 adult patients.

Methodology: Patients who had been diagnosed with COVID-19 microbiologically and/or radiologically between March and October 2020 in a tertiary-care university hospital were enrolled retrospectively.

The Age-Dependent Role of Th22, Tc22, and Tc17 Cells in the Severity of Pneumonia in COVID-19 Immunopathogenesis.

Coronavirus disease 2019 (COVID-19) has clinical manifestations ranging from mild symptoms to respiratory failure, septic shock, and multi-organ failure. Lymphocytes are divided into different subtypes based on their cytokine production pattern. In this study, we investigated the role of cytokine expressions of CD4 T (T helper [Th]1, Th2, Th17, Th22) and CD8 T cell subtypes (T cytotoxic [Tc]1, Tc2, Tc17, Tc22) in the pathogenesis of COVID-19.
