Effectiveness of Fan Therapy for the Management of Dyspnea.

Context: In addition to pharmacological approaches, clinicians use nonpharmacological approaches in the management of dyspnea, one of which is fan therapy. It's a simple, cost-effective intervention that patients can easily use independently, without requiring professional support. The field needs further research on the outcomes of fan use.

An Important Clinical Condition in Differential Diagnosis of Coronavirus Disease 2019: Crack Lung.

Crack cocaine has been associated with a variety of pulmonary manifestations. We report a 44-year-old man been diagnosed with severe acute respiratory syndrome coronavirus 2 infection, presenting shortness of breath, non-productive cough, chest pain, headache, dizziness, and fever lasting for 2 days. At first, all findings of our patient called for an impression of coronavirus disease 2019.

Management of Polydrug-Resistant Tuberculosis.

: There is a lack of information regarding the effective duration of treatment necessary to prevent the development of acquired resistance when fluoroquinolones (FQ), and/or pyrazinamide (Z) resistance has occurred in patients with polydrug-resistant tuberculosis and isoniazid resistance. The management of these kinds of patients should be carried out in experienced centers according to drug susceptibility test results, clinical status of the patient and the extensity of the disease. : We evaluated treatment regimens, treatment outcomes, and drug adverse effects in seven patients with polydrug-resistant tuberculosis, including those with Z and/or FQ resistance in a retrospective analysis : Regarding the patients with polydrug-resistant tuberculosis in addition to isoniazid (H) resistance, three had Z, two had FQ, and the remaining two had both Z and FQ resistance.

Comparison of Pneumonia Severity Indices, qCSI, 4C-Mortality Score and qSOFA in Predicting Mortality in Hospitalized Patients with COVID-19 Pneumonia.

This is a retrospective and observational study on 1511 patients with SARS-CoV-2, who were diagnosed with COVID-19 by real-time PCR testing and hospitalized due to COVID-19 pneumonia. 1511 patients, 879 male (58.17%) and 632 female (41.

Changing characteristics of cancer patients during the COVID-19 pandemic.

Introduction: Cancer patients are more sensitive to infections, and, compared to other patients, may have more serious outcomes. Thus, cancer patients are a high-risk group in the COVID-19 pandemic. The aim of this study was to evaluate how cancer patients are affected by COVID-19 infection; the prevalence, and factors affecting mortality.

Comparison of chest computed tomography findings of RT-PCR negative and RT-PCR positive cases in COVID-19 patients.

Objective: The purpose was to compare the results of the RT-PCR test, with the findings of Chest CT and to determine the features of CT for the diagnosis of COVID-19 and how to approach RT-PCR negative patients.

Material Method: Chest CT findings of 569 COVID-19 diagnosed patients, followed up at the pandemic wards between March and June 2020 were retrospectively examined. Patients were grouped according to RT-PCR results, gender, and age.

Comparison of systemic immune-inflammation index (SII), early warning score (ANDC) and prognostic nutritional index (PNI) in hospitalized patients with malignancy, and their influence on mortality from COVID-19.

Introduction: We evaluated several biological indicators based on inflammation and/or nutritional status, such as systemic immune-inflammation index (SII), early warning score (ANDC) and prognostic nutritional index (PNI) in hospitalized COVID-19 patients with and without malignancies for a prognostic significance.

Methodology: This is a retrospective and observational study on 186 patients with SARS-CoV-2, who were diagnosed with COVID-19 by real-time PCR testing and hospitalized due to COVID-19 pneumonia. 75 patients had various malignancies, and the rest (111), having a similar age and comorbidity profile based on propensity score matching, had no malignancy.
