External validation of the parsimonious EuroLung risk models: analysis of the Brazilian Lung Cancer Registry.

Objective: The purpose of this study was to assess performance in the Brazilian Lung Cancer Registry Database by using the parsimonious EuroLung risk models for morbidity and mortality.

Methods: The EuroLung1 and EuroLung2 models were tested and evaluated through calibration (calibration plot, Brier score, and the Hosmer-Lemeshow test) and discrimination (ROC AUCs), in a national multicenter registry of 1,031 patients undergoing anatomic lung resection.

Results: The evaluation of performance in Brazilian health care facilities utilizing risk-adjustment models, specifically EuroLung1 and EuroLung2, revealed substantial miscalibration, as evidenced by calibration plots and Hosmer-Lemeshow tests in both models.

Ultrasound evaluation in the postoperative period for surgical treatment of thoracic infectious and inflammatory diseases.

Objective: This study aims to evaluate the role of TUSG in the postoperative period and the detection of early complications after surgical treatment, pulmonary resection, or decortication for infectious and inflammatory thoracic diseases, comparing with the standard method (Chest Radiography ‒ CXR).

Methods: Prospective non-randomized self-controlled study. Twenty-one patients over 16 years of age have undergone surgical treatment of inflammatory and infectious lung diseases.

Resident physician training in bedside pleural procedures: A one-year experience at a teaching hospital.

Background And Objective: This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects.

Materials And Methods: The authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023.

Results: 463 chest tube insertions and 200 thoracenteses were performed during the study period.

The association of visceral pleural invasion with skip N2 metastasis on clinical stage IA NSCLC.

Background: Lung lymphatic drainage occurs mainly through a peribronchial path, but it is hypothesized that visceral pleural invasion could alter this path. This study aims to investigate the association between visceral pleural invasion, node upstaging, and N2 skip metastasis and the impact on survival in a population of patients with non-small cell lung cancer of 3 cm or smaller.

Methods: We retrospectively queried our institutional database of lung cancer resection for all patients with clinical stage IA NSCLC between June 2009 and June 2022.

Prolonged survival after thoracic metastasectomy in patients with nonseminomatous testicular cancer.

Introduction: Almost 20 % of patients with Non-Seminomatous Germinative Cell Tumors (NSGCT) will require intrathoracic metastasectomy after chemotherapy. The authors aim to determine their long-term survival rates.

Methods: Retrospective study including patients with NSGCT and intrathoracic metastasis after systemic therapy from January 2011 to June 2022.

Practice patterns and trends in surgical treatment for chronic lung infections: a survey from the Brazilian Society of Thoracic Surgery.

Background: Chronic lung infections represent a diversity of clinical entities that combined respond to significant public health, particularly in developing countries. However, there is no data regarding the practice patterns, surgeons' preferences, and technological usage, especially among Brazilian surgeons, in the setting of the surgical treatment of chronic lung infections. We, therefore, surveyed Brazilian thoracic surgeons from the Brazilian Society of Thoracic Surgery (SBCT) about practice patterns and trends in surgical treatment for chronic lung infections.

Current morbimortality and one-year survival after pneumonectomy for infectious diseases.

Objective: Identify the one-year survival rate and major complications in patients submitted to pneumonectomy for infectious disease.

Methods: Retrospective data from all cases of infectious disease pneumonectomy over the past 10 years were collected from two reference centers. The authors analyzed: patient demographics, etiology, laterality, bronchial stump treatment, presence of previous pulmonary resection, postoperative complications in the first 30 days, the treatment used in pleural complications, and one-year survival rate.

Quality of life in patients with malignant pleural effusion treated with an indwelling pleural catheter in an emerging country.

Background: The use of Indwelling Pleural Catheter (IPC) in the care of patients with Malignant Pleural Effusion (MPE) is well established, however studies involving public health systems of low and middle-income countries are still lacking. This study aimed to determine the effect of IPC on the respiratory symptoms and Quality of Life (QoL) of patients with MPE in the setting of a Brazilian public health system.

Methods: From August 2015 to November 2019, patients with MPE underwent IPC placement and were prospectively followed.

Pneumomediastinum in COVID-19 disease: Outcomes and relation to the Macklin effect.

Aim: Pneumomediastinum (PM) is associated with several etiologies and mechanisms. Although it has been described more than 100 years ago, the literature is limited to small retrospective studies. This study aimed to follow patients with coronavirus disease (COVID-19) that developed PM during hospitalization and describe their clinical and radiological evolution.
