The prognostic effect of concomitant COVID-19 with spontaneous pneumothorax.

Background: The aim of this study was to investigate the prevalence of novel coronavirus disease 2019 (COVID-19) in patients hospitalized with primary spontaneous pneumothorax and to evaluate its possible effects on the clinical course, treatment, and the prognosis.

Methods: Between April 2020 and January 2021, a total of 86 patients (78 males, 8 females; mean age: 27±5 years; range, 16 to 40 years) who had no underlying lung disease and were diagnosed with the first episode of spontaneous pneumothorax were retrospectively analyzed. At the same time of diagnosis, all patients were screened for COVID-19 via polymerase chain reaction test of nasopharyngeal swabs.

Prospective analysis of the physiological changes caused by prolonged use of N95-type masks.

Introduction: The clinical and physiological effects of long-duration use of N95-type masks without ventilation valves, on health-care workers during the coronavirus disease-2019 (COVID-19) pandemic, were evaluated.

Methods: All volunteering personnel working in operating theater or intensive care unit, using nonventilated N95 type respiratory masks, minimum for a 2-h noninterrupted duration were observed. The partial oxygen saturation (SpO) and heart rate (HR) were recorded before wearing the N95 mask and at 1 and 2 h.

Prognostic significance of pathological complete response in non-small cell lung cancer following neoadjuvant treatment.

Background: This study aims to investigate the factors associated with pathological complete response following neoadjuvant treatment and to examine the prognostic value of pathological complete response in patients with non-small cell lung cancer undergoing surgical resection.

Methods: Between February 2009 and January 2016, a total of 112 patients (96 males, 16 females; mean age 60±8 years; range, 37 to 85 years) with the diagnosis of non-small cell lung cancer who underwent anatomical pulmonary resection after neoadjuvant treatment were retrospectively analyzed. Demographic, clinical, radiological, and pathological characteristics of the patients were recorded.

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).
