Look-Locker T1 relaxometry and high-resolution T2 in the evaluation of lung lesions: a single-center prospective study.

Objective: To explore the feasibility of two magnetic resonance imaging (MRI) sequences-high-resolution T2-weighted (HR T2) and Look-Locker T1 (LL T1) relaxometry-for the investigation focal lung lesions (FLLs). As a secondary objective, we analyzed the diagnostic accuracy of these sequences.

Materials And Methods: This was a prospective observational study involving 39 subjects with FLLs scanned in a 1.

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.

Radiomics-based features for pattern recognition of lung cancer histopathology and metastases.

Background And Objectives: lung cancer is the leading cause of cancer-related deaths in the world, and its poor prognosis varies markedly according to tumor staging. Computed tomography (CT) is the imaging modality of choice for lung cancer evaluation, being used for diagnosis and clinical staging. Besides tumor stage, other features, like histopathological subtype, can also add prognostic information.

Report of a lung carcinoma extended to the left atrium through pulmonary vein.

Lung cancers may extend along or grow through the pulmonary veins to invade or lie within the left atrium (LA). A 62-year-old man, previously healthy, presented with 1-month ventilatory-independent right hemithorax back pain, dry cough and large effort dyspnea. He also referred weight loss of 12 kg in 10 months and denied hemoptysis.

Bronchial fistula closure with negative pressure wound therapy: a feasible and cost-effective treatment.

Treatment of bronchial fistula (BF) after pulmonary lobectomy is a challenge. Often, patients require long hospital stay, have recurrent empyema and pneumonia, are susceptible to sepsis, often need broad-spectrum antibiotics, as well as various surgical approaches. With the advent and growing evidence of the benefits of negative pressure therapy (NPT), its use in some patients with BF has been reported with encouraging results concerning its feasibility and cost-effectiveness.

A survey among Brazilian thoracic surgeons about the use of preoperative 2D and 3D images.

Background: Describe the characteristics of how the thoracic surgeon uses the 2D/3D medical imaging to perform surgical planning, clinical practice and teaching in thoracic surgery and check the initial choice and the final choice of the Brazilian Thoracic surgeon as the 2D and 3D models pictures before and after acquiring theoretical knowledge on the generation, manipulation and interactive 3D views.

Methods: A descriptive research type Survey cross to data provided by the Brazilian Thoracic Surgeons (members of the Brazilian Society of Thoracic Surgery) who responded to the online questionnaire via the internet on their computers or personal devices.

Results: Of the 395 invitations visualized distributed by email, 107 surgeons completed the survey.

Performance in the 6-minute walk test and postoperative pulmonary complications in pulmonary surgery: an observational study.

Objectives: To assess functional capacity in the preoperative phase of pulmonary surgery by comparing predicted and obtained values for the six-minute walk test (6MWT) in patients with and without postoperative pulmonary complication (PPC) METHOD: Twenty-one patients in the preoperative phase of open thoracotomy were evaluated using the 6MWT, followed by monitoring of the postoperative evolution of each participant who underwent the routine treatment. Participants were then divided into two groups: the group with PPC and the group without PPC. The results were also compared with the predicted values using reference equations for the 6MWT RESULTS: Over half (57.

Bilateral Shoulder Dysfunction Related to the Lung Resection Area After Thoracotomy.

This study aimed to investigate the mobility, pain, and disability of the shoulders after different pulmonary surgical procedures.It is a cross-sectional prospective study. A total of 38 patients who underwent lung surgery via thoracotomy (mean age = 57 ± 10 years) were evaluated in the preoperative period, and first and second postoperative days were assessed for range of motion of shoulder; pain intensity; and application of the Shoulder Pain and Disability Index questionnaire.

Pulmonary artery sarcoma and chronic thromboembolism.

Pulmonary artery sarcoma is a rare and highly lethal disease whose clinical findings are often indistinguishable from those of chronic thromboembolic pulmonary hypertension. Partial improvement after thrombolytic therapy has suggested that thromboembolic phenomena may be superimposed on the tumor, but, to date, a well-documented statement of these events has not been provided.
