https://doctoremi.com/wp-content/uploads/2020/05/Video-Capture-2.png The following video is from a Facebook Live presentation I did on Saturday, May 23, 2020, co-sponosored by DoctorEmi.com and the Vibrant Wellness Clinic, entitled: COVID-19: Facts, Fiction, and Myths. Here, we've posted the video (in which I fielded live questions during the second half), followed by the Outline and Bibliography.

Outline

1 - COVID-19: how serious is it?

1. The R naught

2. The Complications

3. Comparison with the H1N1 Pandemic

2 - Incubation period and time of asymptomatic patients

3 - Testing

4 - Droplet size

1. Aerosol- size is <= 5 microns- can remain in the air for up to 3 hours.

2. Droplet- >5 microns- generally fall down after 6 feet- sometimes up to 13 feet.

3. Virus size is 90-100 nanometers and the sugical mask has holes of 300 nm- but the theory is the droplet gets stuck in the mask.

4. N95 masks can filter out particles down to 0.3 microns 95 percent of the time.

5 - Masking

1. Respirator versus mask

2. Royal Society DELVE Initiative Graph

3. Surgical mask versus homemade mask

    1. Surgical mask 96%
    2. Vacuum cleaner bag 94%
    3. Dish towel or tea towel 83%- single layer but 97% efficient with double layer but trouble breathing with leak.
    4. Blended tee-shirt 74%
    5. 100% cotton- 69%-70% efficient but less leaking and less trouble breathing; also antimicrobial pillowcases.
    6. Homemade masks are 50 times less efficient in stopping reception than N95 masks and 25% times less than surgical masks.

7 - Nutrition

1. Vitamin D- The evidence is called “circumstantial” because it is not in randomized controlled trial form despite the fact that longitudinal studies looking at hundreds of thousands of people point to reduced mortality from respiratory viruses.

Two-fold role:

1. Production of antimicrobial peptides in the respiratory epithelium, thus making infection with the virus and development of COVID-19 symptoms less likely.

2. Vitamin D might help to reduce the inflammatory response to infection with SARS-CoV-2. Deregulation of this response, especially of the renin–angiotensin system, is characteristic of COVID-19 and degree of overactivation is associated with poorer prognosis. Vitamin D is known to interact with a protein in this pathway—angiotensin-converting enzyme 2 (ACE2)—which is also exploited by SARS-CoV-2 as an entry receptor. While SARS-CoV-2 downregulates expression of ACE2, vitamin D promotes expression of this gene.

2. Intervention trials of Vitamin D have not always shown benefit except one glaring exception:

One important exception to this general trend is for upper respiratory tract infections: a 2017 meta-analysis of individual patient data from 11 321 participants in 25 randomised controlled trials showed that vitamin D supplementation protected against acute respiratory tract infections and that patients with very low (<25 nmol/L) serum 25-hydroxyvitamin D concentrations (a marker of vitamin D status) gained the most benefit.

3. Zinc

4. Vitamin C

1. Meta analysis in 2019 showed IV Vitamin C could shorten the length of stay in the ICU.

2. Dr. Paul Marik

5. NAC- theoretical for COVID- some evidence in influenza

8 - Treatments

1. Hydroxychloroquine plus or minus macrolide- the concern is for a cardiac arrythmia called Torsades – prolonged QT

1. Helps to get zinc inside cells and zinc then stops replication of the virus.

2. Mandeep R Mehra, Sapan S Desai, Frank Ruschitzka, Amit N Patel The Lancet.com, May 22, 2020, “Hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19: a multinational registry analysis."

This trial had no zinc:

3. Initial study done in France was small and poorly designed and only showed that people had nasal swabs go negative faster – no changes in morbidity or mortality- this trial has no zinc.

4. Hydroxychloroquine and Azithromycin plus and minus zinc- Retrospective trial from May 8th showed shorter hospital stays and less likelihood of intubation and ICU admission but did not help late in disease.

5. The Indian government is prophylactically dosing healthcare workers at 400 mg twice daily for 7 days and then 400 mg once a week for the next 7 weeks, and for family members of ill patients the same in the first week and then 400 mg for 3 weeks.

2. Remdesivir

3. Convalescent Plasma

9 - Clinical Trials

1. High Dose IV Zinc

2. Quercetin

10 - Examples of Success

1. Mongolia- it pays to be smart rather than rich

2. Taiwan- Learning from SARS

11 - Vaccines
