Does the Charlson comorbidity index help predict the risk of death in COVID-19 patients?

Objective: Comorbidities are diseases that coexist with a disease of interest or an index disease, which can directly affect the prognosis of the disease of interest or indirectly affect the choice of treatment. The Charlson comorbidity index (CCI) is the most widely used comorbidity index. In this study, it was aimed to examine the predictive role of the CCI score on the mortality of patients with COVID-19.

Evaluation of the cardio-ankle vascular index in COVID-19 patients.

Objective: This study aimed to investigate the relationship and prognostic significance of cardio-ankle vascular index, which is a measure of arterial stiffness that can lead to endothelial dysfunction and poor cardiovascular issues in COVID-19 patients, with COVID-19.

Methods: The study included 115 patients, of which 65 patients in the case group with Real time reversetranscription-polymerasechainreaction test positive and diagnosed for COVID-19 and 50 volunteers in the control group. Patients with COVID-19 were classified as moderate/severe or mild COVID-19 in the subgroup analysis based on the severity of the disease.

Association of severity of allergic rhinitis with neutrophil-to-lymphocyte, eosinophil-to-neutrophil, and eosinophil-to-lymphocyte ratios in adults.

Background: Allergic rhinitis (AR) is characterized by chronic inflammation of the nasal mucosa. T-helper 2 lymphocytes, neutrophils, and eosinophils play an active role during the late-phase immune response after exposure to allergen.

Objective: We aimed to investigate the usefulness of inflammatory parameters of neutro-phil-to-lymphocyte ratio (NLR), eosinophil-to-neutrophil ratio (ENR), and eosinophil-to- lymphocyte ratio (ELR) as markers for distinction between intermittent and persistent allergic rhinitis.

The Role of CO-RADS Scoring System in the Diagnosis of COVID-19 Infection and its Correlation with Clinical Signs.

Background: Computed tomography (CT) evaluation systematics has become necessary to eliminate the difference of opinion among radiologists in evaluating COVID-19 CT findings.

Introduction: The objectives of this study were to evaluate the efficiency of CO-RADS scoring system in our patients with COVID-19 as well as to examine its correlation with clinical and laboratory findings.

Methods: The CO-RADS category of all patients included in the study was determined by a radiologist who did not know the rtRT-PCR test result of the patients, according to the Covid-19 reporting and data system of Mathias Prokop et al.

Evaluation of Diarrhea in Patients with COVID-19.

Background/aims: The COVID-19 disease, which was declared epidemic by the WHO, is a global emergency public health problem. Patients with extrapulmonary symptoms are the group of patients who should be considered for person-to-person transmission in the community. In our study, it was aimed to investigate the characteristics of patients with COVID-19-related diarrhea symptoms.

The relationship between diagnostic value of chest computed tomography imaging and symptom duration in COVID infection.

Objectives: Severe acute respiratory syndrome-coronovirus-2 is a global public health problem, in which early diagnosis is required to prevent the spread of infection. In this study, we aimed to reveal the diagnostic value of chest computed tomography (CT) imaging with respect to symptom duration.

Methods: This retrospective study involved patients from five centers, who were admitted with typical COVID-19 symptoms and found to be positive for COVID-19 real-time reverse transcription-polymerase chain reaction (rtRT-PCR) test.

CT-guided transthoracic fine needle aspiration of pulmonary lesions: accuracy and complications in 134 cases.

The aim of this study was to perform a prospective evaluation of the effectiveness of computed tomography (CT)-guided transthoracic fine needle aspiration (TFNA) in the diagnosis of pulmonary lesions and to determine the complication rate of this procedure. A prospective review was conducted of 134 patients who underwent CT-guided TFNA at our center between December 2003 and August 2005. All fine needle aspirations were performed with a 22-gauge single-pass Chiba needle under CT guidance.

Comparison of bronchoscopic washing and gastric lavage in the diagnosis of smear-negative pulmonary tuberculosis.

Objective: To evaluate the diagnostic contribution and utility of bacteriologic surveys using bronchoscopic washing and gastric lavage in cases of radiologically suspected tuberculosis with no detectable acid-fast bacilli (AFB) in the sputum.

Material And Methods: This prospective study performed bronchoscopic lavage following gastric washing in suspected pulmonary tuberculosis patients. The presence of AFB was determined via direct microscopy and materials were cultured in Löwenstein-Jensen medium.
