Prolonged corticosteroid therapy and lung abnormalities in patients after severe COVID-19 pneumonia.

Background: Some of the hospitalized patients after severe COVID-19 pneumonia experience significant fall in peripheral saturation despite optimal treatment. Because of immune dysregulation in COVID-19 there are indications that prolonged corticosteroids could be considered in treating patients for persistent radiological sequelae and respiratory symptoms.

Objectives: to investigate lung function and lung sequelae on high-resolution CT (HRCT) im COVID-19 patients who were treated with glucocorticoid therapy in two dose regimens with a control group of patients who did not receive additional glucocorticoid therapy.

Longitudinal analysis of chest Q-SPECT/CT in patients with severe COVID-19.

Introduction: Patients with COVID-19 have an increased risk for microvascular lung thrombosis. In order to evaluate the type and prevalence of perfusion defects, we performed a longitudinal analysis of combined perfusion single-photon emission and low-dose computed tomography (Q-SPECT/CT scan) in patients with COVID-19 pneumonia.

Methods: Consecutive patients with severe COVID-19 (B.

Nutritional Assessment of Patients with Primary Progressive Dementia at the Time of Diagnosis.

Background: patients with different types of dementia may experience changes in nutritional status, which are manifested by specific eating habits. The aim of this study was to determine the nutritional status and eating habits of patients at the time of confirmed diagnosis of primary progressive dementia.

Subjects And Methods: The study included 40 outpatients (63% women) diagnosed with either form of dementia.
