COVID-19 Video Updates 61-65


It’s been a busy week at MedCram, as we participated in our first live stream lecture — called COVID-19 Clinical Updates & Lessons Learned So Far with Dr. Seheult — last Thursday. In this free webcast, Dr. Seheult presented key COVID-19 updates, prevention strategies, treatments, and some lessons learned so far, as well as answered thoughtful questions from our viewers. In addition, we partnered with Continuing Education Company to offer 1.5 CME credits for medical professionals who tuned in. 


Blood Clots & Strokes in COVID-19; ACE-2 Receptor; Oxidative Stress

In our 61st COVID-19 update video, Dr. Seheult looks at the numbers of daily new cases and deaths around the globe, before addressing this alarming Washington Post article, describing the occurrence of young and middle aged people with COVID-19 who are getting strokes. 

Related to this, a case study looked at a 72-year-old, otherwise healthy male diagnosed with COVID-19 and found that his blood clots may have been mediated by very high levels of Von Willebrand factor (VWF) and factor VIII in the coagulation cascade. Then, Dr. Seheult dives into the molecular biology of the effects of the SARS-CoV-2 virus on angiotensin-II, leading to vasoconstriction, increased blood pressure, vascular permeability, pulmonary edema, and ARDS.


Treatment with Famotidine (Pepcid)?

In our 62nd coronavirus video update, Dr. Seheult talks about research on famotidine (Pepcid). This research consists of an epidemiological review and separate study looking at the protein structures of SARS-CoV-2 and various medications, which led to a discreet clinical trial looking at treatments of famotidine with hydroxychloroquine versus just hydroxychloroquine versus historical controls. 

Moreover, Dr. Seheult picks up on the idea of oxidative stress and COVID-19’s impact and damage on the endothelium, which he continues in-depth in the next update video. 


Is COVID-19 a Disease of the Endothelium (Blood Vessels and Clots)?

In the 63rd COVID-19 update, Dr. Seheult dives right in by explaining the possibility of COVID-19 as a disease of the endothelium (the thin layer of cells lining the inside of arteries). First, he reviews the basics of oxidative stress, starting with mitochondria, leading to biochemical explanations of the electron transport chain, ATP, and the role of superoxide molecules in oxidative stress and disease.

Dr. Seheult then applies this knowledge and information to this article, which examines the role of angiotensin converting enzyme-2 (ACE2) — the target of SARS-CoV-2 — in endothelial dysfunction and atherosclerosis.


Remdesivir COVID-19 Treatment Update

Our 64th coronavirus pandemic update focuses on Remdesivir, citing this article from the Lancet describing a study from ten hospitals in China. The study compared Remdesivir versus placebo, and did show a statistical significance between the groups. Interestingly, the NIH released a separate article on the same day, referencing a U.S. study looking at Remdesivir, which showed a statistically significant decreased recovery time for the Remdesivir group compared to the placebo group and a nearly statistically significant lower mortality rate for the Remdesivir group compared to the placebo patients. 


COVID-19 and Oxidative Stress (Prevention & Risk Factors)

Finally, in our 65th COVID-19 update video, Dr. Seheult revisits oxidative stress, discussing angiotensin-II’s role in the production of reactive oxygen species (ROS). He also explains the function of polymorphonuclear leukocytes (PMNs) secreting superoxide in COVID-19. Overall, this video presents a schematic suggesting that the SARS-CoV-2 virus creates an environment within the body that tips the scale toward oxidative stress. This provides a reasonable explanation as to why patients with comorbidities like obesity and hypertension are at higher risk for thrombosis related to COVID-19, as reported in previously discussed articles on COVID-19 patients dying of strokes.

    I have been watching your COVID-19 videos mainly on YouTube. Clear and wonderful explantations! I wonder if Dr Seheult has heard of Dr Judy Mikovitz. (She wrote Plague of Corruption) She explains that the COVID-19 pandemic is caused by not just coronavirus but the gamma retroviruses that many patients carry and many of the confounding signs and symptoms are due to these additional dormant viruses in the patients system.

    I have done some research into possible Superoxide inhibitors and found that there are good evidence that “Ursolic Acid” can
    help inhibit Superoxide. It is an OTC
    supplement well known to the
    fitness community.
    articles/PMC4216084/ (among other references.)
    Coupled with vitamin A,C,E,
    Melatonin and NAC, for their antioxidant properties may help preserve endothelial integrity. In some cases, a daily “baby Aspirin” (100 mg) for it’s antiplatlet activity may also prove beneficial in reducing risks related to clotting.
    Ofcourse we should not forget the value of Zinc, QUERCETIN and vitamin D, as has already been suggested by Dr Seheult in previous videos.

    Grateful to know what the Medcram community think of the above.

    Many thanks to the Medcram team for accompanying us through this pandemic with up to date valuable information. I raise my hat to that!

    Keep up the good work and above all, do keep safe.

    Dear Med Cram

    Thank you for the helpful corona virus updates.

    I wanted to have a more nuanced discussion about the idea of race and impact on corona virus outcomes.

    Since race is a social construct, those studies purporting to describe biochemical differences between races should be carefully considered to make sure that comparisons are apples to Apple. If two arbitrary (social) populations (black and white or say short and tall) are compared, one may find biochemical, genetic or epigenetic differences but it may remain unclear if these are caused by environmental factors (I.e stress) or are linked to „skin color“ I.e race.

    Genetic differences purported to be caused by genes are difficult to prove (see:
    And race / genetic studies on blacks from America rarely control for admixture of African and European genes, (up to 75% via the one drop rule) making it unclear exactly what is being measured.
    The question remains often if there is any significance to a gene that segregates with one of the 7 genes that control skin color, which is currently how we unscientifically tend to classify people into racial groups.

    When genetic differences are found in black/white „races“ the question of if the environment (I.e. diet, stress, gene phosphorylation) has a role in the observed difference or if a real genetic trait is being observed.

    There is the tendency to want see race as a real category with somehow more significance than any other observed trait (height, eye color) and black / white publications that do not clearly define these categories as social and arbitrary contribute to incorrect understanding of race.

    See: There’s No Scientific Basis for Race—It’s a Made-Up Label

    Thank you

    Kind regards

    Sonya Faber
