When Death Is NOT Theoretical: The Readiness of the Music Group ‘Queen’ for Living with Freddie Mercury’s Dying [2nd edition, 2018]
Most considerations of Queen and its musical catalogue have been by journalists, but Dr. Powell approaches these questions as an historian and clinician, analyzing fifty-some songs and mobilizing extensive amounts of data to support his conclusions. — excerpt from description of When Death is NOT Theoretical, Amazon

Pentoxifylline: A Versatile Off-Patent Medication Best Not Overlooked
Some Published Medical Thoughts (as of February 19th, 2022) about
COVID-19 & Pentoxifylline
(a phosphodiesterase 4 inhibitor ) (a production inhibitor of TNF-alpha, IL-6, & IL-2R -- all of which are higher in COVID-19 infection)

Previous studies have shown that PTX has anti-inflammatory effects and, therefore, may be beneficial in countering the cytokine storm caused by COVID-19. This drug has also been shown to reduce lung fibrosis in patients with COVID-19, as well as to prevent thromboembolic events. Therefore, PTX may exert potential benefits in treating the symptoms of SARS-CoV-2 as well as its complications.” [bolding added]
[in early 2022, the role of fibrin clots in COVID-19 deaths became more appreciated.

The cohorts were similar in age, gender, body mass index, comorbidities, Sequential Organ Failure Assessment (SOFA) score, and mortality. More patients with COVID-19 (100% vs 70% ...) required anticoagulation. Ex vivo fibrin clots formed from patients with COVID-19 appeared to be denser and to have smaller pores than those from patients with sepsis but without COVID-19 …. We found aberrant fibrin clot structure and function in critically ill patients with COVID-19. These findings may contribute to the poor outcomes observed in COVID-19 patients with widespread fibrin deposition.” bolding added]
