Importance of Insulin Resistance in the COVID-19 Era: A Retrospective Analysis of a Single Center in Mexico.

Introduction and objectives Type 2 diabetes mellitus (T2DM) has been one of the main risk factors associated with mortality from the coronavirus disease 2019 (COVID-19). Insulin resistance (IR) is a preceding and underlying condition of T2DM, which has been thought that it could increase mortality from COVID-19 since it favors the entry of severe acute respiratory syndrome coronavirus type 2 in the host cell. This article reports a biochemical study that estimated the prevalence of IR in COVID-19 patients and non-diabetic patients without COVID-19 history.

A survivor woman after three years of a cardiac tamponade.

Primary pericardial mesothelioma is an extremely rare tumor, of unclear etiology, nonspecific presentation, with a delay in diagnosis, and a poor prognosis. We present the case of a woman with pericardial mesothelioma, whose main manifestation was cardiac tamponade, currently alive three years after diagnosis and undergoing chemotherapy treatment. < Cardiac tamponade can be the first clinical manifestation of a neoplastic disease, including pericardial mesothelioma, so an adequate diagnostic approach should always be carried out in patients with this clinical picture.
