We welcomed back Dr. Michael Schmidt for updates and more information regarding Personal Spaceflight Medicine. Note that the abstract referenced in the second segment has been uploaded to the blog for this show.  During the first segment of our 92 minute program, Dr. Schmidt defined personal spaceflight medicine for us & talked about targeting individuals for specific countermeasures to human factors risks for longer duration spaceflight safety.  We talked about artificial gravity and radiation with our listeners asking questions about both fields.  Our guest cited several examples to make his point.  At one point he talked about the current twin study underway on the year long plus ISS experiment with a Russian cosmonaut as well.  Questions were asked about using pharmaceuticals in space, how they might react with different people, and the distribution methods so far which are not great.  At one point, Dr. Doug emailed in asking about the use of omics for space travel issues and if in fact the use of omics would reveal even more questions that cannot be answered, ultimately delaying long duration HSF missions even longer than they are delayed now.  Don’t miss the guest response to Doug’s question.  Kris emailed in asking about the use of deliberate hypothermia to store Mars bound astronauts, and then another Doug question came in about selecting the best people based on omics for a mission.  Near the end of the segment, I asked our guest if he had done work for Mars One. He explained their limited capacity relationship which I assume ended.

In the second segment, BJohn asked about the possibility of astronauts sleeping in a small vertical centrifuge.  Dr. Rowe called to talk about the issue relating to pharmaceutical use in space.  he talked about delivery methods, malabsorption, etc.  Later, Dr. Schmidt brought up the damage done from sleep deprivation and showed how this is a potential problem for space missions.  Doug emailed in a question about GCRs and radiation, then Dr. Schmidt talked about his new paper on BDNF with his associate Dr. thomas Goodwin, “Protecting Neural Structures and Cognitive Function During Prolonged Space Flight by Targeting The Brain Derived Neurotrophic Factor Molecular Network.”  We talked about BDNF and spaceflight, exercises, mitigation measures, and more. He referenced Mars simulation, behavioral issues and more. You don’t want to miss this discussion.  Dr. Schmidt provided us with excellent closing remarks.

Personalized Medicine for Human Space Flight

Guests:  Dr. Michael Schmidt, Dr. Thomas Goodwin.  Topics:  We discuss the recent published reviewed paper by our guess, “Personalized medicine in human space flight: using Omics based analysis to develop individualized countermeasures that enhance astronaut safety and performance.”  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm.  We welcomed both Dr. Michael Schmidt and Dr. Thomas Goodwin to this 1 hour 28 minute program to discuss their findings represented in their recent published & reviewed paper, “Personalized medicine in human space flight: using Omics based analysis to develop individualized countermeasures that enhance astronaut safety and performance.” I’ve posted this paper on The Space Show blog and I urge you to read it as I believe it will the way of the future for human spaceflight astronaut safety and enhancement.

We started our discussion with Dr. Schmidt stating the problem(s) with astronauts in the extreme space environment, longer mission duration stress, plus other factors.  Dr. Schmidt followed by Dr. Goodwin then explained and discussed personalized medicine in human space flight and the use of Omics analysis.  Their work was also applied to the emerging space tourism industry as well as for suborbital missions.  Regarding the suborbital flights, the interest seems to be more with the pilots who will be making many trips to space rather than the participant who will likely be doing it only once.  Our guests put forth the reasoning for personalized space flight medicine, we talked about the capabilities to do this screening and the studies today, what will be near term and what we can expect over the longer term as technologies develop.  Listeners asked about conventional mitigation strategies such as shielding, exercise, etc.  Our guests pointed out that they were not talking about eliminating the usual mitigation strategies but tailoring needs to an individual’s DNA and genetic makeup since  individual astronauts may have genetic and DNA differences that will respond better to a customized mitigation.  We talked about varying degrees of DNA stability & unstable DNA.  Much was said about the effects of RX medications and drug profiles.

In our second segment, we talked more about the suborbital flights and the interest in the pilots due to their repeat flights.  We talked about targeted RX medications for an individual, how medications are metabolized & how that might actually differ in the astronauts leading to customization.  Doug asked about a type of primate ISS experiment regarding fractionalized gravity.  Listeners also wanted to know about adding mass and cost to a mission due to personalized space flight medicine which as you will hear, was not the case.  In the concluding comments, our guests pointed out that personalized space flight medicine was going to be the future of human space flight.  Personalized and target DNA and genetic medicine is already starting to happen here on Earth so its extension to space is only natural.
