Impact of COVID-19 on pre-existing liver disease.

Patients with chronic liver disease of any etiology who become infected with SARS-CoV-2 have been found to have a higher risk of mortality compared to those patients who do not have chronic liver disease. A literature review was conducted in the relationship between COVID 19 and preexistence of liver disease.

Fenotipos de la enfermedad por reflujo gastroesofágico: una visión basada en su fisiopatología.

The advancement of knowledge in pathophysiology and underlying etiologies of gastroesophageal reflux disease (GERD) has allowed the development of the concept of disease beyond the acidity of reflux. The variability in the symptom presentation and the response to treatment cannot be attributed only to reflux composition, since esophageal factors, such as structural, mechanical, biochemical, and physiological aspects, play an important role. The proposed personalized approach to GERD uses a stepwise approach that optimizes performance and phenotypic outcome while minimizing invasiveness, risk, and cost.
