Clinical Profile and Course of Patients with Acute Respiratory Distress Syndrome due to COVID-19 in a Middle-Income Region in Mexico.

Introduction: COVID-19 leads to severe clinical complications that culminate in respiratory failure and acute respiratory distress syndrome (ARDS). Despite reports of some comorbidities that contribute to the development of COVID-19-mediated ARDS, there is great variation in mortality rates among critical COVID-19 patients in the world. To date, no studies have described the incidence and comorbidities associated with ARDS due to COVID-19 in the northeastern region of Mexico.

Sepsis, mitochondrial failure and multiple organ dysfunction.

Purpose: The purpose of this review is to consider the state of oxidative stress, failure of the antioxidant systems and mitochondrial failure as the main physiopathological mechanisms leading to multiple organ dysfunction during sepsis.

Principal Findings: Sepsis is a clinical syndrome caused by a severe infection that triggers an exaggerated inflammatory response. Involved in the pathogenesis of sepsis are the activation of inflammatory, immune, hormonal, metabolic and bioenergetic responses.
