Survivors SPEAK OUT! . . . . . David Figurski . . . . . . . . . . . . . . . 20-Year Post-Injury Anniversary

On April 8, 2014, Donna published my Survivor SPEAK OUT! interview to begin her series of interviews about the experiences and thoughts of survivors and caregivers. Since then, Donna has published over 130 written interviews in which people answer Donna’s twenty survivor- or caregiver-specific questions to let the readers know their stories, tell of their lives, and give first-hand, and often hard-earned, advice for other survivors and caregivers.

In my original interview, I kept my answers short so others wouldn’t be intimidated. I didn’t need to. Other interviewees were not reluctant at all to discuss at length many of the aspects of their brain injuries. In this interview on the 20th anniversary of my TBI (traumatic brain injury), I hope to give you a more detailed look at my past and present life.

1. What is your name? (last name optional)

David Figurski

2. Where do you live? (city and/or state and/or country) Email (optional)

Surprise, Arizona, USA                  dhfdmf@aol.com

3. On what date did you have your brain injury? At what age?

January 13, 2005          At age 57

4. How did your brain injury occur?

Each morning before showering, I would do Tai Chi warmup exercises and calisthenics. One day, my brain hemorrhaged on my 13th chin-up. 

5. When did you (or someone) first realize you had a problem?

I felt something happen in my head, but I didn’t have any pain, so I wasn’t concerned. I stopped exercising because I was seeing double. When my double-vision didn’t clear after a minute or so, I walked down the hall to where my wife (Donna) was getting ready for her job of teaching first-graders. I was exceptionally lucky that day – luck that gave me twenty years more (so far) of life. Normally, I got up at 4:00 am and left for my lab at Columbia University in New York City by 5:30 am. But I was planning to work at home that day to prepare a talk, so I got up later and overlapped Donna’s morning schedule. It turned out to be crucial because Donna saved my life. By the time I got to her, I was in crisis. She immediately saw that my right eye was filled with blood. Not long after, I felt something else happening in my head, and I began experiencing extreme pain. Donna dialed 9-1-1 to get emergency help. I became unintelligible because I was slurring my words. When the paramedics put an oxygen mask on me, the pain subsided, but I slipped into a coma, which lasted nearly three weeks.

6. What kind of emergency treatment, if any, did you have?

The paramedics took me to the Emergency Room of a nearby hospital where Donna made her first life-or-death decision – that I have immediate surgery instead of a CAT (computerized tomography) scan to see if the pressure from the brain-bleed had decreased. It’s clear now that the time that would been taken to do a CAT scan would have decreased my chance of survival by several hundred-fold.

But Donna’s nightmare was only beginning. Over the next two weeks, she had to give permission for two more surgeries on my brain. My chance of survival continued to be low.

After the first surgery, I was carefully transferred by ambulance to Columbia-Presbyterian Hospital in New York City. There, the neurosurgeon discovered an aneurysm that had to be removed. That was the second surgery. I survived … but the neurosurgeon had more bad news for Donna. She had to give permission for another dangerous surgery – to remove an AVM (arteriovenous malformation), a tangle of arteries and veins that can be a “time-bomb.” Miraculously, I survived that surgery too.

(The neurosurgeon at the local hospital for the first surgery was highly skilled, but he gets an F-grade for his manner. His first words after introducing himself to Donna were that I “would make a great organ-donor”!)

7. Were you in a coma? If so, how long?

Yes. I was in a coma for nearly three weeks.

8. Did you do rehab? What kind of rehab (i.e., inpatient or outpatient and occupational and/or physical and/or speech and/or other)? How long were you in rehab?

Yes. A couple of weeks after my surgeries at Columbia-Presbyterian, I was transferred to Radburn Rehabilitation Hospital, which specializes in helping patients with brain injuries. There I had inpatient therapies (physical, occupational, and speech) three days a week for three hours per day. I was discharged from Radburn after about two months, but I continued with outpatient therapies – first at Radburn for three months, and then for two of months at Dominican Hospital in Santa Cruz, California, where our son lives, and then back at Radburn for about a year. 

A year after my brain-hemorrhage, I went back to my lab at Columbia University as a volunteer to direct my research group. After I stopped going to Radburn for outpatient therapies (about eighteen months after my brain-hemorrhage), I returned to Columbia University as full-time faculty member. I had a standing appointment for two hours each week with a physical therapist, who worked with me in my office until I retired at the end of August 2013.

9. What problems or disabilities, if any, resulted from your brain injury
(e.g., balance, perception, personality, etc.)?

Fortunately, my hemorrhage was at the back of the brain, so no cognitive, memory, or major personality changes resulted from my TBI. I gave lectures, wrote and was awarded a multi-year research grant from the National Institutes of Health, mentored Ph.D. students and postdoctoral scientists, and wrote and published scientific papers. In short, I had my scientific life back – which was really important to me.

But because my cerebellum and brain-stem were primarily affected, I do have several physical disabilities.

I have double-vision from a defective nerve-muscle connection in my right eye. The right side of my face droops from being paralyzed. (The loss of my ability to smile caused me to lose an important part of my self.) My swallow has been affected. It is difficult to eat some foods, and I am always in danger of aspirating. Because the right side of my tongue is paralyzed, it’s difficult to make some sounds and pronounce certain words. (For that reason, I talk less and use fewer words. I have to be careful not to sound curt or rude.) I talk more slowly, and my voice has changed because my vocal cords were affected. (My slower speech allows me to substitute a word mid-sentence to one I can more easily pronounce.) My right arm is ataxic. I can use my left arm and hand for most things, but they are not as good as they once were. (For example, it’s difficult to use my left arm to raise a glass to my mouth, and it’s impossible to do so without shaking.) My right leg is weaker than it was, and my right ankle does not automatically flex the way it should. (I have to consciously focus on my ankle for it to bend properly.) At night, I get up to go to the bathroom about every 90 minutes because I have frequent urinary urges. (Thankfully, this is not a problem during the day.) The cerebellum, which is located at the back of the brain and controls balance, was severely damaged by my hemorrhage. Consequently, my balance is really poor. Donna and I hold each other whenever I walk outside or in a strange environment, like a restaurant. In the house, where the floors are even, I can walk short distances. I use a rollator (4-wheeled walker) for longer walks in the house and an electric scooter for airports and long distances outside.

I feel extremely fortunate that all my disabilities are physical. Of course, my life is now very limited, but I can still read, write, and communicate by using my computer – with my left hand.

10. How has your life changed? Is it better? Is it worse?

Early on, I stopped thinking about what I could no longer do. Instead, I emphasized what I could still do. I then became totally comfortable with my life, and, as a result, my life now is better than it was in many ways. Of course, I would say it’s worse if I continued to grieve what I lost, but I consider that part of my life as gone, like my youth. So I don’t think about what I lost, except to be thankful that I had the chances to do what I did.

11. What do you miss the most from your pre-brain-injury life?

I do miss a couple of things from my pre-TBI life. I miss leaving the house on my own. I miss just doing what I wanted to do without having to carefully plan. I miss Donna’s and my dinner conversations. (Because my damaged cerebellum caused a loss of coordination between my tongue and my teeth, I have to pay close attention to chewing. So Donna and I don’t speak when I’m eating.) I was racing cars, so I desperately miss driving. While I have a device that scans a page and reads it to me, I miss having normal vision and reading books.

12. What do you enjoy most in your post-brain-injury life?

It’s hard to imagine, but my TBI caused me to improve in some areas. Things are much slower (because of my disabilities), so I can’t do as much as I once did. Because I’m slower, I’ve learned to be more efficient and more organized with the time I am able to work. Because I spend nearly all of my time at home, I have more time to be a part of Donna’s life. I have also bonded more closely with and have enjoyed more our dog, a Maltese-Poodle. Koda is a 2-year-old male rescue.

13. What do you like least about your brain injury?

I intensely dislike my loss of balance. It’s an issue that’s a burden not only for me, but also for Donna, who helps me walk whenever we go anywhere.

14. Has anything helped you to accept your brain injury?

I’ve been greatly helped by the positivity of most doctors; the nurses; the therapists; the staff; the Columbia faculty, students, and postdoctoral scientists; and many of the people I’ve come in contact with. But, by far, the greatest help has come from my wife, Donna – the most positive person I know. She cheers every gain – no matter how small. She constantly looks out for me, for example, choosing the easiest path in a restaurant, finding and researching an electric scooter, and bringing home several samples of items so I can choose.

15. Has your injury affected your home life and relationships and, if so, how?

My home life has indeed been affected. I no longer do repairs, so Donna does them. I can’t lift heavy objects, so Donna does what she can and gets help if she needs to. Donna and I do collaborate on some projects. We once had to assemble a piece of furniture. The assembly was complicated, so I laid everything out and understood the directions. I would tell Donna what tool to use and what to do. She was great – she did everything perfectly! Now we have a useful and beautiful cabinet. I used to do everything financial. Now Donna does. She pays the bills, gets everything ready for the tax preparer, and successfully negotiated the deal for our car. I am home a lot more, so we have more time to talk. Among our many conversations are talks about what she and I are feeling in our new life that resulted from my brain injury.

16. Has your social life been altered or changed and, if so, how?

Donna and I weren’t overly social. We continue to socialize in small groups of family and close friends. In the past, our focus was on our two children – and on each other at our weekly “date nights.” Now, we not only focus on our children, but also on their spouses and our grandchildren. Nothing much changed after my TBI, except that I’m always at home and we don’t go out to eat as much anymore.

17. Who is your main caregiver? Do you understand what it takes to be a caregiver?

My wife, Donna, has always been my main caregiver. She was with me from the very beginning of my brain injury. Her first acts of caregiving for me were to call 9-1-1 before I slipped into a coma and to advocate for me in the hospitals. Survivors need to realize how heroic their caregivers usually are, how devoted caregivers are to caring for their survivors, how caregivers’ lives have also been severely disrupted – in these cases by brain injury, and how caregivers are often frightened by their survivors’ brain injuries and shocked by the changes to their survivors’ lives. Donna is always using her experiences and knowledge to help other caregivers with what is often an overwhelming responsibility. Donna has published an award-winning memoir (Prisoners Without Bars: A Caregiver’s Tale), which began as daily updates for family and friends around the country. In her updates, she discussed my progress or lack of progress for the day. Later, Donna wrote down what happened in a series of essays to have a record for me. About a year after my hospitalization, she began to read her essays to me. I was shocked by her horrific experience and convinced her to write a book. She did, and a publisher (WriteLife) was interested in her caregiver’s perspective on brain injury. (You can listen to the book trailer below.)

18. What are your plans? What do you expect/hope to be doing ten years from now

In ten years, I expect to continue to focus on the lives of family and friends, continue to learn about and explain science to the public, continue to discuss brain injury with other survivors and with caregivers, continue to help the public understand brain injury, and continue to make Donna’s life as easy as possible.

19. Are you able to provide a helpful hint that may have taken you a long time to learn, but which you wished you had known earlier? If so, please state what it is to potentially help other survivors with your specific kind of brain injury.

Years after my TBI, I gained a perspective that helped me. It’s typical to blame your disability when it takes far longer to accomplish something than you think it should or when you can’t do something you think you should. What helps me is to realize the body is doing the best it can. This minor change of attitude has ended much of my frustration of feeling inadequate. So go easy on yourself.

20. What advice would you offer to other brain-injury survivors? Do you have any other comments that you would like to add?

I can’t emphasize enough the importance of surrounding yourself with positive people. Such people have had a crucial and beneficial effect on my self-esteem. For example, Donna has not only been my caregiver, but she is also my cheerleader. I had an excellent neurologist for years, but then we moved across the country. I found a new neurologist, but Donna and I didn’t feel any positivity from him, so we never returned. Likewise, if a doctor or therapist tells you you can’t do something, and it’s only his or her opinion and is not based experience or data, you may want to find someone else. It’s important for you too to have a positive attitude. At the very least, consider that you survived! Your positive attitude will affect others, especially your caregiver, who is often overwhelmed and who will not be further burdened by your feeling sorry for yourself.

Long COVID . . . . . . . . . . . . . . Serious Long-term Effect of Some COVID-19 Infections

Long COVID – a Serious Long-term Effect of Some COVID-19 Infections


by


Columbia University Professor Emeritus, Dr. David Figurski

presented by

Donna O’Donnell Figurski

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 <severe acute respiratory syndrome coronavirus #2> and the disease it causes as COVID-19 <coronavirus infectious disease of 2019>.  Because the majority of people, including most of the press, commonly refer to the virus as “COVID-19” or “COVID,” to avoid confusion, I use “COVID-19” as the name of the virus.)

Finally – the news I’ve been waiting for!

Bottom line: The news is good … if you’re vaccinated.

Dr. Daniel Griffin, a Columbia University infectious disease physician, has said that long COVID is a public health crisis.  Several million people worldwide are living with the mysterious, often disabling, ailments of long COVID.

What is long COVID?

Everybody knows about the acute phase of COVID-19 infection. Some infections are serious and require hospitalization – and maybe intensive care. However, infected people and even the survivors of hospitalization seem to fully recover. They feel fine and test negative for the virus.coronavirus_PNG38

But weeks or months later, people who appear to have recovered from a COVID-19 infection may experience any one or several symptoms, which include fatigue, severe headaches, brain fog, anxiety, depression, muscle pain, cough, fever, cognitive impairment, joint pain, chest pain, shortness of breath, vertigo or loss of balance, memory issues, rash, heart palpitations, and sleep issues.

What’s worse – the symptoms can persist. No one knows when the symptoms will end. Some long COVID patients worry that their symptoms will be lifelong. Society needs to be ready for many more disabled people.

Scientists and doctors don’t know the cause.

Particularly worrisome is the fact that even asymptomatic and mild infections can lead to long COVID. Since vaccination still permits asymptomatic and mild infections but prevents the severe infections that require hospitalization, I have been concerned that long COVID can still occur with vaccination. Now it’s clear that vaccination prevents long COVID too.

Because long COVID occurs weeks or months after a COVID-19 infection, it took a while for the data on vaccination and long COVID to come out.

apps.31154.13510798883188545.eeff598f-9fb6-4eae-b36b-53296e4adb2eA recent paper submitted by an Israeli group showed there is a significant reduction (an appropriately conservative conclusion for data that showed 0 cases of long COVID) if a person was vaccinated before getting infected.  In contrast, with no vaccination, about half of hospitalized COVID-19 patients will get long COVID. Vaccination after getting COVID-19 helps: Vaccination within 30 days of COVID-19 infection helps reduce the incidence of long COVID significantly. Getting vaccinated 30-60 days after COVID-19 infection helped, but not as much as within 30 days. Getting vaccinated after 90 days post COVID-19 infection does not help.

You can listen to Dr. Griffin talk about long COVID in two short segments – minutes 38:25-41:30 and 47:25-50:15 – of his clinical update in the video podcast (TWiV #856 – This Week in Virology by Columbia virologist Dr. Racaniello.

COVID-19: Long COVID and Children

Long COVID and Children
by
Columbia University Professor Emeritus, Dr. David Figurski
presented by
Donna O’Donnell Figurski

 

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19.  Because the majority of people, including much of the press, commonly refer to the virus as “COVID-19,” to avoid confusion, I use COVID-19 as the name of the virus.)

David H. Figurski, Ph.D & Survivor of Brain Injury

It has been accepted that the infection of teens and children with COVID-19 rarely results in significant symptoms, but it’s worrisome that they may be as susceptible as anyone else to a recently identified effect of COVID-19 – a syndrome called “long COVID.”

Children with the virus often show no signs of infection, and sometimes they (and their parents) are not even aware that they have been infected.  Contrast that with the experiences of the very old.  Infection of the elderly often leads to severe disease and can result in death.  Nobody has yet been able to explain how age results in the radical difference in sensitivity to the effects of the virus.

Doctors and scientists are also unable to explain the onset of the delayed symptoms of long COVID.  In one study, 10-13% of children who knew they were infected thought they had recovered.  They tested negative for the virus, and most of their symptoms were gone. In some cases, there were several weeks of good health. But weeks or months later, they showed new symptoms. (Adult symptoms include fatigue; fever; cough; sore throat; chest pain; shortness of breath; neurocognitive problems with memory, concentration, processing, or finding words; diarrhea; headaches; insomnia; dizziness; heart palpitations; abdominal cramps, rashes; tinnitus; joint pain; depression; and anxiety.) The symptoms may last weeks or months, and some people still have symptoms after several months.

Particularly worrisome is the fact that mild or asymptomatic acute infections can still lead to long COVID.  This means that children, who were thought to be unbothered by infection, are, in fact, sensitive to long COVID.

I haven’t seen the data, but I suspect that the 10-13% number came from people who either had an obvious symptom or tested positive.  If we include the number of asymptomatic infections, the percentage of infected children who get long COVID will likely go down significantly.  If you and your children are using masks and social-distancing, then you’re already at a low risk of even getting infected.

The bottom line is that this virus still shows surprises. It’s definitely too early to relax.

COVID-19: The President’s Infection (Part 4 of 4)

COVID-19: The President’s Infection (Part 4 of 4)

by

Columbia University Professor Emeritus, Dr. David Figurski

presented by

Donna O’Donnell Figurski

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19. Because the majority of people, including much of the press, commonly refer to the virus as “COVID-19,” to avoid confusion I use COVID-19 as the name of the virus in this post.)

David H. Figurski, Ph.D & Survivor of Brain Injury

The President returned to the White House Monday evening. Was that too soon? Was the President at risk? Was he contagious?

The President’s doctors at Walter Reed were comfortable with his leaving the hospital because the White House has its own doctors and medical facility. Remdesivir is given IV for five days. Putting in an IV line would not be a problem at the White House. If the President needed supplemental oxygen, a chest X-ray, antibiotics, etc., they are readily available. The doctors at the White House can also do the daily blood tests needed to monitor the state of the President’s immune system and his propensity for clotting. Dexamethasone is usually prescribed for ten days, but an oral form is available.

Two important questions loomed. Is the President immune? And, is the President contagious?

The conferral of immunity by COVID-19 infection is a major question yet to be answered. If there is protective immunity and, if so, how long it lasts are major concerns of vaccine producers. There are now reports of people being infected with COVID-19 a second time. Immunity may depend on the severity of the initial infection and the robustness of the consequent immune response. There has been a report of mild or asymptomatic infections that do not elicit an antibody response. Are these people more vulnerable to a second infection? Alternatively, was their response so effective without antibodies that the virus could not become established and cause symptoms?

Is the President contagious? We can’t say without knowing his test results. Dr. Griffin considers a patient virus-free if that person has two negative tests on two consecutive days. Otherwise, a person is considered to be potentially contagious for 20 days. Since the doctors are permitting the President to hold rallies, I assume he is not thought to be contagious.

Dr. Griffin’s extensive experience with COVID-19 patients has allowed us to surmise what was happening with the President’s infection. The President appears to have completely recovered from his COVID-19 infection. But, several questions remain.

COVID-19: The President’s Infection (Part 1 of 4)

by

Columbia University Professor Emeritus, Dr. David Figurski

presented by

Donna O’Donnell Figurski

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19. Because the majority of people, including much of the press, commonly refer to the virus as “COVID-19,” to avoid confusion I use COVID-19 as the name of the virus in this post.)

This is an unusually long post, so I’ve divided it into four parts. It is easy to read, even though it’s filled with much information.

David H. Figurski, Ph.D & Survivor of Brain Injury

The complete story of the President’s COVID-19 infection and treatment is not known by the public. Virologist, Dr. Vincent Racaniello, interviewed Dr. Daniel Griffin, a New York City physician who has been treating hospitalized COVID-19 patients since the beginning of the pandemic. Vincent has been releasing podcasts about COVID-19 every couple of days. His TWiV podcast (This Week in Virology) of October 5, 2020, is a special podcast in which he and Dr. Griffin have a conversation about COVID-19 infection and treatments, as they relate to the President’s infection.

Vincent Racaniello is a professor and virologist and my former colleague in the Department of Microbiology & Immunology at Columbia University. His guest, Daniel Griffin, is a physician in the Infectious Disease Department of Columbia. Because Dr. Griffin has both an M.D. and a Ph.D., he is a physician-scientist and so has an additional appointment as Professor of Biochemistry & Molecular Biophysics. Dr. Griffin is also the Chief of the Division of Infectious Disease for ProHEALTH Care Associates. ProHEALTH Care is the largest physician-owned multi-specialty practice in the nation. He is also on the COVID-19 response team for the tri-state area.

Dr. Griffin has applied his clinical and molecular knowledge of COVID-19 to the few details we know about President Trump’s infection. In doing so, we now have a better idea of the President’s case. I urge you to listen to the complete 34-minute TWiV podcast of October 5th. I have defined some terms and explained some concepts that may be unfamiliar to you.

President Trump announced at 1:00 am on Friday, October 2, 2020, that he and the First Lady tested positive for COVID-19. Later that day, the President was admitted to Walter Reed National Military Medical Center. He returned to the White House at 6:30 pm the next Monday. Many of the details of the infection and the President’s condition have remained unknown.

When the President’s COVID-19 infection began is unclear. The President first reported a positive test in the early morning of October 2nd. The President said he is not tested for COVID-19 every day, and the White House will not say when the President’s last negative test occurred. In his Town Hall on October 15th, the President said he didn’t know for sure that he had taken a test before the debate three days before he was admitted.

COVID-19 — It’s Everywhere . . . Breakthrough in Basic Research May Defeat COVID-19

Breakthrough in Basic Research May Defeat COVID-19

by

Columbia University Professor Emeritus, Dr. David Figurski

presented by

Donna O’Donnell Figurski

 

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19. Because the majority of people, including much of the press, commonly refers to the virus as “COVID-19,” to avoid confusion I use COVID-19 as the name of the virus in these posts.)

David H. Figurski, Ph.D & Survivor of Brain Injury

 

Exciting results indicate that a novel idea might bring COVID-19 under control.  The new technology has been shown to work at the lab bench.  Now scientists are doing animal studies and, later, human studies.

Scientists at Boston University (BU) and the University of California at San Diego (UCSD) have made coated nanoparticles that are covered with pieces of lung cell membrane. (About 1000 tiny particles, or “nanoparticles,” can line up in the space equal to the width of a human hair.) The coated nanoparticles mimic the lung cells that normally bind the virus and allow an infection to start.  But, when the virus tries to infect a coated nanoparticle, the virus dies.  Essentially, the coated nanoparticle is a lethal decoy.

Research in the lab indicates that the new technology might be able to end the COVID-19 pandemic. Also, if the technology works in humans, coated nanoparticles will likely be important for inactivating other viruses and for dealing with future pandemics.

Specific nanoparticles can be made to mimic any cell that any virus infects.  So, coated nanoparticles can be made that are specific for any virus (for example, for influenza virus or for Ebola virus).  Also, once the cell normally infected by a previously unknown virus to start an infection has been identified (as it was for COVID-19), the relevant coated nanoparticles can be made. So, a novel virus can be inactivated even though little is known about the molecular details of its biology.

Scientists were surprised to learn that the coated nanoparticles for COVID-19 bind the SARS-2 coronavirus even better than the lung cells normally infected by the virus.  So, this approach for COVID-19 is likely be very efficient.

In COVID-19 infections, sometimes the immune response is too active and causes severe disease or death.  The dexamethasone breakthrough I wrote about earlier works by dampening the immune response.  The scientists surprisingly found that coating another batch of nanoparticles with membrane pieces from cells of the immune system also dampened the immune response.

The scientists envision a protective coated nanoparticle mixture for COVID-19 that has two types of coated nanoparticles (one that mimics the lung cells that are infected and another that dampens the immune response). The mixture would be simply administered as a nasal spray.

COVID-19 — It’s Everywhere . . . Drug Breakthrough Significantly Prevents COVID-19 Deaths

Drug Breakthrough Significantly Prevents COVID-19 Deaths

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19. Because the majority of people, including much of the press, commonly refer to the virus as “COVID-19,” to avoid confusion I use COVID-19 as the name of the virus in these posts.)

COVID-19

David H. Figurski, Ph.D & Survivor of Brain Injury

Research at the University of Oxford in England showed for the first time that a drug prevented a major fraction of deaths in severely sick patients with COVID-19.

Dexamethasone was found in a large clinical trial to cause a significant reduction in deaths. It can be prescribed as pills, and it is a common, readily available, and relatively inexpensive drug

A major problem after infection by COVID-19 is that the immune response of some individuals is too aggressive (often causing what’s called a “cytokine storm”) and can lead to death. Because dexamethasone is a steroid that dampens the immune response, the prediction was that it might help to prevent deaths by COVID-19.

The research showed that it does.

There are about 3 deaths for every 8 patients on ventilators.  Dexamethasone treatment reduced those deaths by one-third.  So, 1 death would be prevented for every 8 patients on ventilators.  About 5 deaths occur in every 25 patients on oxygen only. Dexamethasone treatment reduced those deaths by one-fifth, or about 1 less death for every 25 patients on oxygen only. Dexamethasone treatment had no effect on patients not on ventilators or receiving oxygen only.

Given that a major fraction of the over 118,000 deaths in the US so far (at 6:00 pm ET on June 18, 2020) were on ventilators or oxygen only, dexamethasone treatment is predicted to prevent many deaths.

The UK’s Chief Scientific Adviser, Sir Patrick Vallance, said: “This is a ground-breaking development in our fight against the disease, and the speed at which researchers have progressed finding an effective treatment is truly remarkable.”

COVID-19 — It’s Everywhere . . . Progress in Controlling COVID-19

Progress in Controlling COVID-19

COVID-19

I want to tell you about an amazing podcast, TWiV (This Week in Virology), created and hosted by Dr. Vincent Racaniello, a colleague of mine at Columbia University.

Vincent’s a virologist who has done cutting edge research on the molecular biology of influenza virus, poliovirus, and rhinoviruses (which cause the common cold). His podcasts feature several PhDs in microbiology (virologists, an immunologist, a parasitologist, and a science reporter who earned his PhD with Vincent) discussing the latest research and advances in viruses.

Vincent has been self-quarantining at home. Consequently, since March 13th, he has made more than 30 podcasts, nearly all concerning COVID-19, potential therapies and vaccines, and pandemics. His guests have been infectious disease scientists doing research or physicians in the trenches learning about the clinical manifestations of the virus and how to treat their patients.

Dr. Vincent Racaniello – Columbia University Virologist

Vincent’s podcasts are made for non-scientists to understand, but they are 1-2 hours long. Probably none of you has the time to listen that long. Therefore, I’m trying to listen to them so I can point you to episodes and minutes you may want to hear.

Podcast #622, released June 2, featured Dr. Emmie de Wit of the Rocky Mountain Labs in Montana. She’s a virologist doing drug and vaccine research in monkeys. Because Rocky Mountain Labs is one of the few places in the country with a high-safety-level facility, Dr. de Wit has worked with several dangerous viruses: SARS-1, MERS, pandemic influenza strains, and Ebola. Now she’s working with SARS-2.

I’ve boiled down Episode #622 to four segments totaling ~16 minutes.

  1. 26:05-26:35 – The spike protein of the virus coat initiates infection of a cell by attaching to the ACE2 protein (angiotensin converting enzyme 2) on the cell’s surface. Here Emmie tells how it took only days to identify ACE2 and confirm viral binding. Rich Condit, a virologist, was astonished by the speed. ACE2-binding by spike is a potential drug target.

 

  1. 37:15-39:44 – The PCR test (polymerase chain reaction), simple enough to be done on a large scale, detects the 30,000-nucleotide (or base) RNA chromosome of the virus. But, PCR is so sensitive that it can detect degradation fragments of the RNA, even though the person is no longer contagious. The only way to tell for sure is to detect viable virus in cell culture. This is hard to do and is only done in virology research labs. As a result, a person is considered infected and contagious if the PCR test is positive.

  1. 43:35-54:05 Remdesivir, an antiviral drug, is a nucleotide-analog that blocks the copying of the RNA chromosome to make more virus. Emmie showed that giving remdesivir to monkeys early (at 12-hours post infection) was very effective. But, humans don’t show symptoms for days, and, because remdesivir must be administered intravenously, patients are only given remdesivir if they are hospitalized. This is very late, and still there is a modest effect. Rich Condit talks about the possibility of producing an oral form of the drug. Then remdesivir could be taken earlier – maybe even at home – and might be very effective in humans.

 

  1. 58:25-60:40 This segment concerns a vaccine. (I’ll write more on this topic later, but you should know that there are three types of promising technologies: the viral protein-based, the viral gene-based, and the virus vector-based, in which a harmless virus carries a gene from a disease-producing virus for a protein that’s needed to infect cells.)2ff087415a5009984739aa8fde5d5d4a

Emmie tested a harmless chimpanzee adenovirus that was engineered to carry the COVID-19 spike gene. This adenovirus produces the coronavirus spike protein, needed for COVID-19 to infect cells. So, this harmless adenovirus should cause us to make antibodies that will block infection by COVID-19.

In Emmie’s experiment in monkeys, the vaccine worked so well that it allowed clinical trials to proceed in humans.

COVID-19 — It’s Everywhere . . . Vaccine is Possible

COVID-19 . . . Evidence that a Vaccine is Possible

by

Columbia University Professor Emeritus, Dr. David Figurski

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19.  Because the majority of people, including much of the press, commonly refer to the virus as “COVID-19,” to avoid confusion, I use COVID-19 as the name of the virus in these posts.)

COVID-19

The 100+ labs trying to develop a vaccine for COVID-19 were delighted with a study showing that COVID-19 stimulates a strong antibody response in humans. Scientists from the University of California at San Diego (UCSD) demonstrated that a vaccine for COVID-19 is definitely possible.

The scientists studied blood from mildly sick individuals who recovered. They found a high level of antibodies to the spike protein, used by COVID-19 to infect.

The strong antibody response suggests that immunity will occur in humans and will last a while, but no one knows for how long – weeks? months? years?

The scientists were surprised by another result. For you also to understand it, I have to give you some background. (Sorry!)

There are seven coronaviruses that infect humans.

Four are common and cause mild, cold-like symptoms.  We’ve all probably had one or more of these.

Three coronaviruses (SARS-CoV, SARS-CoV-2 <which causes COVID-19>, and MERS- CoV) cause serious human disease and some fatalities.

Blood taken before COVID-19 even existed in humans nevertheless showed the presence of antibodies that reacted with COVID-19.  Infection with one of the mild coronaviruses may have stimulated the body’s production of some antibodies that cross-react with COVID-19.

Some seemingly healthy individuals have died from COVID-19. In contrast, some people not predicted to do well had mild disease or were asymptomatic. Doctors are perplexed by their inability to predict who will recover.

David H. Figurski, Ph.D & Survivor of Brain Injury

One possibility is that the amount of cross-reactive antibodies arising from previous infection with one or more of the mild coronaviruses may determine how well a COVID-19-infected person will do.

David Figurski, PhD – a few months before brain injury

… The waiting room was huge. There were couches in clusters—some small, some large, each with a table in the middle. The groupings reminded me of The Clan of the Cave Bear by Jean Auel that I read many years ago. Auel wrote about prehistoric man, the Clan people. She told how each family gathered around its hearth at night. The hearth was a private place. It was illustration-of-a-caveman-family-dancing-around-a-bonfire_158190224-1considered impolite to peer into someone else’s hearth. That’s the way it felt in the waiting room too …
