Proportional weight loss in six months as a risk factor for mortality in stage IV non-small cell lung cancer.

Objective: To evaluate different weight loss (WL) cut-off points as prognostic markers of 3-month survival after diagnosis of stage IV non-small cell lung cancer (NSCLC).

Methods: This was a prospective study involving 104 patients with metastatic (stage IV) NSCLC who were admitted to a cancer treatment center in southern Brazil between January of 2014 and November of 2016. We evaluated total WL and WL per month, as well as WL and WL per month in the 6 months preceding the diagnosis.

Predictors of noncompliance to pulmonary tuberculosis treatment: An insight from South America.

Purpose: To investigate the factors associated with a higher risk of noncompliance to tuberculosis (TB) treatment in Porto Alegre, Brazil.

Methods: We identified 478 adult patients for this case-control study undergoing treatment for confirmed pulmonary TB. Cases (noncompliance) were defined as patients who stopped treatment for more than 30 consecutive days (n = 118).

What is expected in lung function after lung transplantation due to end-stage pulmonary silicosis?

In this study, we aimed to determine the impact of lung transplantation (LTx) on pulmonary function tests (PFTs) and survival among patients with end-stage silicosis. We included patients with end-stage silicosis on the wait list for LTx, between January 1989 and July 2015 (N = 26). Sixteen of these patients received LTx; 10 were eligible, but did not undergo LTx (non-LTx) during the study period.

Twelve-year survival of the first living-donor pediatric lung transplantation in Brazil.

Objective: To report the long-term follow-up of the first living-donor lobar lung transplantation performed in Latin America.

Description: The patient was a 12-year-old boy with post-infectious obliterative bronchiolitis with end-stage pulmonary disease. He was on continuous oxygen support, presenting with dyspnea even during minimal activity.
