During the first segment, Dr. Rowe focused on a possible astronaut magnesium deficiency that would cause cardiovascular problems, especially with a space walk. Dr. Rowe explained why, talked about the adrenalin levels being 2 times those on Earth plus decreased plasma levels. He spent some time explaining these issues, their relationships to one another and why he believes them to be risk factors. In his discussion, he referenced health conditions for some of the Apollo era astronauts, plus he talked about microgravity issues and a possible mitigation strategy of using I.V. saline with the astronauts in space. At times the discussion was medically and technically complex but Bill broke it down for those of us not in the medical profession. He also talked about his experience over decades of practicing medicine and being a diagnostician, referencing many of his relevant patient studies along the way, including for example his work with Sy Mah. Dr. Doug sent in an email regarding dehydration and a headward fluid shift. Toward the end of the first segment, Dr. Doug called in to suggest that if an astronaut did an EVA in a pressurized rover vehicle rather than an Apollo era spacesuit, adrenalin levels and other risks would be mitigated. This was an interesting discussion with Dr. Rowe who did not agree with Doug's premise. Listen and let us know what you think by posting on TSS blog. In the second segment, Dr. Rowe started off saying more about the use of I.V. saline with astronauts, a topic he discussed in the first segment. . BJohn had several email questions asking about spacesuit gloves and exoskeleton gloves given what Dr. Rowe was saying about finger tips and related items. Other topics discussed in this segment included the ISS, the one year Twins Study, Vitamin D usage in space, iron risks for spaceflight, plus the implication for some of these space risks to the problem of terrestrial urban pollution. As he has done before, Bill advocated for the need to have subcutaneous pharmaceutical administration for astronauts, then he addressed issues relating to the calcium-magnesium ratio. Bill provided us with a good set of concluding comments, plus he suggested healthy guidelines for our lives right here on Earth. Please post your comments/questions on TSS blog above.
