Donna O’Donnell Figurski – author

Donna & David with ARC of Prisoners without Bars: A Caregiver’s Tale

 

My memoir, Prisoners without Bars: A Caregiver’s Tale, is not only a story of David’s and my struggles after his traumatic brain injury, but it is also a love story. Though my memoir addresses a dire topic, it is peppered with comedic situations. They say laughter is the best medicine, and again, they are right.

Prisoners without Bars is a heart-wrenching memoir that will make you laugh, cry, and G-A-S-P. I promise!

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

Drug Breakthrough Significantly Prevents COVID-19 Deaths

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 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

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

 

 

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

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 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.

COVID-19

David Columbia Award May 2017Because the COVID-19 pandemic has affected everyone, including the brain injury community, I have added a new category called “COVID-19” to this blog. This category is for posting much-needed information and facts on the new coronavirus and the global pandemic it has caused.

The major reason I added the COVID-19 category is that I have unique access to a survivor of brain injury who is knowledgeable about this pandemic.

For 35 years, my husband, David, was a professor and did research in the Department of Microbiology & Immunology at Columbia University. He retired on September 1, 2013. In January 2005, David had a cerebellar hemorrhage. He survived a three-week

coronavirus-covid-19-design-vector

coma and three brain surgeries in the first two weeks of his coma. Unfortunately, he was left with many physical disabilities, but his cognitive brain was untouched, allowing him to return full-time to the faculty after 19 months. (Those 19 months are described in detail in my book Prisoners without Bars: A Caregiver’s Tale.) For 45 years, David did research on the molecular genetics of various microorganisms, including viruses.

02 Fork Yield Banner copyTo allow you to be introduced to David, I am reposting the link to my radio show of April 19, 2020, on the Brain Injury Radio Network called,  “Another Fork in the Road: BI Survivor/Columbia Prof Dr. David Figurski & Covid19.” (The link first appeared in my post on May 4, 2020.) David was my guest, and I interviewed him about his brain injury and about COVID-19. (Our discussion of COVID-19 begins at 49:50.)

New NEWS: Dr. David Figurski Speaks Out About Coronavirus

Dr. David Figurski Speaks Out About Coronavirus

David Columbia Award May 2017

Professor David Figurski        Columbia University College of Physicians &Surgeons

 

“In graduate school, I worked with a virus that infects bacterial cells (bacteriophage T1). One T1 virus particle takes about 10-12 minutes to break open the E. coli cell and release over 100 new virus particles. Each new particle can infect a cell and produce over a hundred new virus particles. So, 10-12 minutes later, there are 10,000 viruses. I could do some experiments in the morning and have the results that afternoon.

Random Petri Plate

To make stocks of the virus, we would infect a late culture of bacteria. A couple of hours later, all the bacterial cells were broken open, leaving only virus.

Coronavirus

 

 

 

Animal viruses, like coronavirus, probably take hours to reproduce, but each infected cell produces at least a thousand new virus particles.

Consequently, I have a healthy respect for viruses.”

David Figurski 2004 Pre-Brain Injury

David Figurski – pre-brain injury

My husband, David, bought a Catrike 700 in April 2015.  He rides three days each week, 15 miles each day. David loves his trike. Despite not being able to walk outside unassisted because of a balance problem, he feels “normal” when he rides. He has found that people have a lot of curiosity about the trike. People have stopped him to ask questions. One woman talked to him from her car when they were at a Stop sign.

David is excited because he just broke 2,500 miles. But he still has a ways to go before he equals the 5,390 miles ridden by Dan Zimmerman and Catherine Brubaker on their cross-country trek.

David’s cumulative mileage as of 10/13/16               2,580 mi

Miles to reach 5,390* miles                                          2,810 mi

UPDATE:

David’s cumulative mileage as of 09/04/117               3,727 mi
