"Personalized Medicine in Human Space Flight" Listed Among Most Influential Papers of 2013 and 2014

Posted on by

"Personalized Medicine in Human Space Flight"byMichael A. Schmidt, Ph.D. andThomas J. Goodwin, Ph.D. was recently featured by Springer Science Media,highlighting the most influential articles of the past two years.

Specifically, "Personalized Medicine in Human Space Flight" was among the three most downloaded scientific papers published in 2013 and 2014 from Springer in the journalMetabolomics. In their paper, theauthors lay out a sophisticated case for how personalized medicine may transform the way humans explore the space environment.

According to Dr. Schmidt, "The ability to analyze the genome, epigenome, transcriptome, proteome, and metabolome has deepened our understanding of the uniqueness of individuals and of how individual vulnerabilities may be further revealed under the extreme conditions of space. We and our colleagues are working to translate this complexity into personalized countermeasure solutions that enhance astronaut safety and performance on specific missions, like the ISS, Moon, and Mars."

Dr. Goodwin states, "There is sufficient evidence to deploy certain personalized countermeasures for astronautstoday. Beyond this, we suggest a path where the space medicine community craft a scientific roadmap aimed at broadening development of personalized countermeasures for the near and far term."

Source: "Personalized Medicine in Human Space Flight: Using Omics Based Analyses to Develop Individualized Countermeasures that Enhance Astronaut Safety and Performance," (Schmidt, MA, Goodwin, TJ. Metabolomics 2013;9(6):1134-1156).

Michael A. Schmidt, Ph.D.is the founder of Sovaris Aerospace, LLC. He has developed Omics training programs atGeorge Washington UniversitySchool Health Sciences and is on the Omics Applications Expert Panel for the European Society for Translational Medicine. Dr. Schmidt has ongoing human performance collaborations at NASA Johnson Space Center and NASA Ames Research Center.His work is focused on human performance in extreme conditions and, also, on translating that work to athletic performance and clinical medicine.

Thomas J. Goodwin, Ph.D.is Manager of the Disease Modeling & Tissue Analogues Laboratory, Biomedical Research and Environmental Sciences Division, and is the Lead Scientist for Oxidative Stress and Damage at NASA Johnson Space Center. He is also the Chair of the Omics Applications Expert Panel for the European Society for Translational Medicine (EUSTM).

How Mayo's "Dr. Google" Deal Disrupts Medicine

Posted on by

Dr. Google Google has joined the Mayo Clinic, quietly signaling a powerful disruption for all of medicine.

Back in 1997 I wrote: The information age is to medicine as the Protestant Reformation was to the Catholic Church. The Church didnt disappear when information once held tightly by the priesthood became widely available, but religion changed forever.

My search engine, the doctor

In that context, Mayos agreement to produceclinical summaries under itsnamefor common Google medical searchesis like a medieval pope happily handing out Bible translations. The mission of the most-used search engine on the planet is to make the worlds information universally accessible and useful. Mayo, in contrast, has for decades been a global symbol of doctor-knows-best. Recommending a Google search as the first stop for those needing health information, in the words of a Mayo physician executive, represents a true paradigm change.

But theres much more going on here than search. From the Fitbit to medicines front lines, information technology is forcing a new doctor-patient relationship with new rules for new roles.

If information is power, digitized information is distributed power. While patient-centered care has been directed by professionals towards patients, collaborative health what some call participatory medicine or person-centric care shifts the perspective from the patient outwards.

Collaboration means sharing. At places like Mayo and Houstons MD Anderson Cancer Center, the doctors detailed notes, long seen only by other clinicians, are available through a mobile app for patients to see when they choose and share how they wish. mHealth makes the process mundane, while the content makes it an utterly radical act.

About 5 million patients nationwide currently have electronic access to open notes. Bostons Beth Israel Deaconess Medical Center and a few other institutions are planning to allow patients to make additions and corrections to what they call OurNotes. Not surprisingly, many doctors remain mortified by this medical sacrilege. Even more threatening is an imminent deluge of patient-generated health data churned out by a growing list of products from major consumer companies. Sensors are being incorporated into wearables, watches, smartphones and (in a Ford prototype) even a car that cares with biometric sensors in the seat and steering wheel. Sitting in your suddenly becomes telemedicine.

To be sure, traditional information channels remain. For example, a doctor-prescribed, Food and Drug Administration-approved app uses sensors and personalized analytics to prevent severe asthma attacks. Increasingly common, though, is digitized data that doesnt need a doctor at all. For example, a Microsoft fitness band not only provides constant heart rate monitoring, according to a New York Times review, but is part of a health platform employing algorithms to deliver actionable information and contextual analysis. By comparison, Dr. Google belongs in a Norman Rockwell painting.

These participative technologies have helped supercharge online patient communities, which by one estimate include about one in five Americans with a common chronic condition. Peer-to-Peer health care, as Pew calls it, has helped turn self-reported symptoms and therapeutic responses into crowd-sourced data points. Peers can also point the way to tools such as a consumer version of a sophisticated symptom checker or a medical-grade calculator of surgical risk. The aging of digital natives will only accelerate this trend.

Penn Medicine: Brain activity can predict increased fat intake following sleep deprivation

Posted on by

PHILADELPHIA - Experts have warned for years that insufficient sleep can lead to weight gain. A new Penn Medicine study found that not only do we consume more food following a night of total sleep deprivation, but we also we consume more fat and less carbohydrates and a region of the brain known as the salience network is what may lead us to eat more fat. The new findings are published in Scientific Reports.

Most research in this arena has focused on changes in metabolic hormones that lead to weight gain, while only a few have begun to examine how changes in brain activity may play a role. "We wanted to uncover whether changes in regional brain function had an impact on our eating behavior following sleep deprivation," says the study's senior author, Hengyi Rao, PhD, a research assistant professor of Cognitive Neuroimaging in Neurology and Psychiatry. "This work has implications for the approximately 15 million Americans who work the evening shift, night shift, rotating shifts, or other employer arranged irregular schedules."

The study took a unique approach and sequestered 34 sleep-deprived subjects and 12 controls in a sleep lab for five days and four nights for round-the-clock monitoring. All study subjects received one night of regular sleep and were then randomized to either total sleep deprivation or control for the remaining three nights. Baseline functional MRI (fMRI) to examine brain connectivity changes associated with macronutrient intake was conducted on all subjects the morning following the first night of sleep. Sleep-deprived subjects were matched to control subjects in age, body mass index (BMI), ethnicity or gender.

On the second night, sleep deprivation subjects were kept awake while the control subjects slept for eight hours. fMRI testing of both groups continued on days, two, three and four at the same time each day. All subjects had access to a variety of foods that they could consume as desired.

Sleep deprived subjects consumed close to 1,000 calories during overnight wakefulness. Despite this, they consumed a similar amount of calories the day following sleep deprivation as they did the day following baseline sleep. However, when comparing the macronutrient intake between the two days, researchers found that healthy adults consumed a greater percentage of calories from fat and a lower percentage of calories from carbohydrates during the day following total sleep deprivation.

The Penn researchers also found that sleep deprived subjects displayed increased connectivity within the "salience network," which is thought to play a role in determining contextually dependent behavioral responses to stimuli that can be either internal or external, and is one of several key brain networks that carry out various aspects of brain function. Moreover, increased connectivity in the salience network correlated positively with the percentage of calories consumed from fat and negatively correlated with the percentage of carbohydrates after sleep deprivation. The salience network is located toward the front of the brain and consists of three sections, the dorsal anterior cingulate cortex, bilateral putamen, and bilateral anterior insula. Activity in these structures is linked to both emotion and bodily sensations, such as the heart racing, stomach churning, pain, thirst, embarrassment, and attempting mental challenges. Changes in caloric intake and content after sleep deprivation may therefore relate to changes in the "salience" of food, and in particular fatty food, in individuals who are sleep deprived.

"We believe this is the first study to examine the connection between brain network connectivity and actual macronutrient intake after baseline sleep and after total sleep deprivation," says Rao. Most similar studies rely on self-reported hunger levels of food cravings, or on brain responses to pictures of different types of foods. "Although this study examined the effects of acute total sleep deprivation, similar changes may occur in response to the chronic partial sleep restriction that is so prevalent in today's society."
