[Coinfection of COVID-19 and extrapulmonary tuberculosis].

The SARS-CoV-2 coronavirus pandemic continues causing significant global morbidity and mortality. COVID-19 is an acute respiratory infection that can affect other organs. Tuberculosis (TB) is also an endemic infection that typically occurs with pulmonary involvement and very infrequently, with extra-pulmonary involvement.

[Survival in a cohort of patients with chronic obstructive pulmonary disease according to GOLD 2017 classification].

Until now, there is no information on the evolution of patients with chronic obstructive pulmonary disease (COPD) according to the new GOLD classification. The objective of this study was to determine, in a cohort of patients with COPD followed by twenty years, the impact of the change to the new classification: survival by groups and their association with other variables such as comorbidities. COPD patients (GOLD 2017 definition) were evaluated with follow-up since January 1996 to December 2016.
