Evolution and long‑term respiratory sequelae after severe COVID-19 pneumonia: nitric oxide diffusion measurement value.

Introduction: There are no published studies assessing the evolution of combined determination of the lung diffusing capacity for both nitric oxide and carbon monoxide (DL and DL) 12 months after the discharge of patients with COVID-19 pneumonia.

Methods: Prospective cohort study which included patients who were assessed both 3 and 12 months after an episode of SARS-CoV-2 pneumonia. Their clinical status, health condition, lung function testings (LFTs) results (spirometry, DL-DL analysis, and six-minute walk test), and chest X-ray/computed tomography scan images were compared.

Alterations in Respiratory Function Test Three Months after Hospitalisation for COVID-19 Pneumonia: Value of Determining Nitric Oxide Diffusion.

Unlabelled: Three to four months after hospitalisation for COVID-19 pneumonia, the most frequently described alteration in respiratory function tests (RFTs) is decreased carbon monoxide transfer capacity (DL).

Methods: This is a prospective cohort study that included patients hospitalised because of SARS-CoV-2 pneumonia, three months after their discharge. A clinical evaluation, analytical parameters, chest X-ray, six-minute walk test, spirometry and DL-DL analysis were performed.

Influence of the type of emphysema in the relationship between COPD and lung cancer.

Introduction: There are no studies analyzing the relationship between emphysema and lung cancer (LC). With this aim and in order to make some comparisons between different clinical variables, we carried out the present study.

Methods: This is a case-control study, patients with COPD and LC being the cases and subjects with stable COPD being the controls.

Thoracic ultrasound-assisted selection for pleural biopsy with Abrams needle.

Background: Closed pleural biopsy (CPB) in patients with malignant pleural effusion is less sensitive than cytology. Ultrasound-assisted CPB allows biopsies to be performed in the lower thoracic parietal pleura, where secondary spread from pleural metastases is initially more likely to be found. We analyzed whether choosing the point of entry for CPB with thoracic ultrasound assistance influences the diagnostic yield in malignant pleural effusion.

Thoracic amyloidosis: high-resolution computed tomographic findings in 3 cases.

We report 3 cases of 3 types of thoracic amyloidosis (tracheobronchial amyloidosis, nodular parenchymal amyloidosis, and lymph node amyloidosis) with an emphasis on computed tomographic features. Thoracic amyloidosis is a rare disease, but we think it is important to know its different types and understand how it manifests itself to be able to recognize it.
