Multi-Organ Histopathological Changes in a Mouse Hepatitis Virus Model of COVID-19.

Infection with SARS-CoV-2, the virus responsible for the global COVID-19 pandemic, causes a respiratory illness that can severely impact other organ systems and is possibly precipitated by cytokine storm, septic shock, thrombosis, and oxidative stress. SARS-CoV-2 infected individuals may be asymptomatic or may experience mild, moderate, or severe symptoms with or without pneumonia. The mechanisms by which SARS-CoV-2 infects humans are largely unknown.

Longitudinal Observations on the Mineral Metabolism of Dialysis Patients at the University Hospital.

A retrospective review was performed from November 2011 through June 2012 in 49 stable patients receiving ambulatory hemodialysis at the dialysis unit of the University Hospital in San Juan. Measurements of serum phosphate, serum calcium (corrected to albumin levels), intact parathyroid hormone (PTH), and pulse pressure were obtained at 3-month intervals over the course of a 9-month observation period. These longitudinal observations assessed the efficiency of treatment, with the objective being to determine the nature of and then implement such changes as would improve the patients' outcomes.
