Assessment of respiratory function and exercise tolerance at 4-6 months after COVID-19 infection in patients with pneumonia of different severity.

Background: The evaluation of COVID-19 systemic consequences is a wide research field in which respiratory function assessment has a pivotal role. However, the available data in the literature are still sparse and need further strengthening.

Aim: To assess respiratory function 4-6 months after hospital discharge based on lung disease severity in patients who overcome COVID-19 pneumonia.

A prospective evaluation of lung function at three and six months in patients with previous SARS-COV-2 pneumonia.

Objective: This study investigated the consequences of Coronavirus Disease 2019 (COVID-19) pneumonia on lung function in the first 6 months after hospital discharge.

Methods: A prospective lung function assessment in SARS-CoV2 patients with COVID-19 pneumonia, hospitalized between March and April 2020, was conducted with spirometry measurements including lung volumes, mainly total lung capacity (TLC), lung diffusion capacity for carbon monoxide (DL) collected at 3 months after hospital discharge. Patients with restrictive ventilatory defect or impaired DL or both were re-evaluated at 6 months with global spirometry and chest HRCT scan.

Spontaneous synchronous bilateral hemothorax as the only finding in primary pleural angiosarcoma: a case report and a literature review.

Angiosarcoma is a rare malignancy of vascular origin, mostly originating from skin, soft tissues, and breast, but rarely also from the pleura. We present the case of a 55-year-old man who referred to our hospital for a spontaneous bilateral hemothorax. The CT angiography did not show any source of active bleeding; plus, no pleural or lung masses were observable.

Dyspnea During Night-Time and at Early Morning in Patients with Stable COPD is Associated with Supine Tidal Expiratory Flow Limitation.

Rationale: Patients with chronic obstructive pulmonary disorder (COPD) complain of various COPD-related symptoms with different daily frequencies. During the night-time and at early morning, dyspnea is often reported and may predict an increased risk of COPD exacerbation and hospitalization and all-cause mortality. The aim of the study was to assess the underlying mechanisms of this symptom, seeking functional biomarkers of its occurrence.
