[Leuko-glycemic index in patients with ST elevation myocardial infarction].

Background: The myocardial infarction-associated (MI) mortality is not only due cardiovascular complications, but intrahospital non-cardiovascular complications (IHnCVCs). The leuko-glycemic index (LGI) has been used as a prognostic marker for the development of cardiovascular complications in MI. We focused this study on identifying the cut-off point of LGI for the IHnCVCs development in patients with ST-segment elevation myocardial infarction (STEMI).

Risk Factors and Outcomes for COVID-19 in Autoimmune Inflammatory Diseases during the SARS-CoV-2 Pandemic: A Comparative Study.

Background: Patients with autoimmune disease (AID) and coronavirus disease 2019 (COVID-19) could have higher mortality due to the co-morbidity and the use of immunosuppressive therapy.

Objectives: To analyze the risk factors and outcomes of patients with AID and COVID-19 versus a control group.

Methods: A prospective cohort study included patients with and without AID and COVID-19.

[Pulmonary alveolar proteinosis. Report of a case].

Background: The pulmonary alveolar proteinosis (PAP) is characterized by the accumulation of lipoprotein material in the alveoli. It is classified as primary, secondary and congenital. The primary form, of autoimmune origin, is characterized by antibodies against granulocyte-macrophage colony stimulating factor (GM-CSF).
