Spontaneous Subcapsular Renal Hematoma as Cause of Hypovolemic Shock in a Chronic Hemodialysis Patient.

Subcapsular renal hematomas may appear spontaneously in patients in chronic hemodialysis, though other causes as neoplasms, vasculitis, and infections should be excluded. Patients may present with abdominal pain and hemorrhagic shock; hence, early diagnosis is vital. Nephrectomy or renal artery embolization are suitable treatment options.

Physiological Network Is Disrupted in Severe COVID-19.

The human body is a complex system maintained in homeostasis thanks to the interactions between multiple physiological regulation systems. When faced with physical or biological perturbations, this system must react by keeping a balance between adaptability and robustness. The SARS-COV-2 virus infection poses an immune system challenge that tests the organism's homeostatic response.

Serum Vitamin D Levels Are Associated With Increased COVID-19 Severity and Mortality Independent of Whole-Body and Visceral Adiposity.

Introduction: Coronavirus disease (COVID-19) is a global pandemic. Vitamin D deficiency has been associated with susceptibility to infectious disease. In this study, the association between COVID-19 outcomes and vitamin D levels in patients attending a COVID-19 reference center in Mexico City are examined.

Epicardial adipose tissue thickness is associated with increased COVID-19 severity and mortality.

Background: Increased adiposity and visceral obesity have been linked to adverse COVID-19 outcomes. The amount of epicardial adipose tissue (EAT) may have relevant implications given its proximity to the heart and lungs. Here, we explored the role of EAT in increasing the risk for COVID-19 adverse outcomes.

Familial hypercholesterolemia in Mexico: Initial insights from the national registry.

Background: Familial hypercholesterolemia (FH) remains underdiagnosed and undertreated.

Objective: Report the results of the first years (2017-2019) of the Mexican FH registry.

Methods: There are 60 investigators, representing 28 federal states, participating in the registry.
