Bellagio II Report: Terrestrial Applications of Space Medicine Research.

AbstractINTRODUCTION: For over 50 yr, investigators have studied the physiological adaptations of the human system during short- and long-duration spaceflight exposures. Much of the knowledge gained in developing health countermeasures for astronauts onboard the International Space Station demonstrate terrestrial applications. To date, a systematic process for translating these space applications to terrestrial human health has yet to be defined.METHODS: In the summer of 2017, a team of 38 international scientists launched the Bellagio ll Summit Initiative. The goals of the Summit were: 1) To identify space medicine findings and countermeasures with highest probability for future terrestrial applications; and 2) To develop a roadmap for translation of these countermeasures to future terrestrial application. The team reviewed public domain literature, NASA databases, and evidence books within the framework of the five-stage National Institutes of Health (NIH) translation science model, and the NASA two-stage translation model. Teams then analyzed and discussed interdisciplinary findings to determine the most significant evidence-based countermeasures sufficiently developed for terrestrial application.RESULTS: Teams identified published human spaceflight research and applied translational science models to define mature products for terrestrial clinical practice.CONCLUSIONS: The Bellagio ll Summit identified a snapshot of space medicine research and mature science with the highest probability of translation and developed a Roadmap of terrestrial application from space medicine-derived countermeasures. These evidence-based findings can provide guidance regarding the terrestrial applications of best practices, countermeasures, and clinical protocols currently used in spaceflight.Sides MB, Johnston SL III, Sirek A, Lee PH, Blue RS, Antonsen EL, Basner M, Douglas GL, Epstein A, Flynn-Evans EE, Gallagher MB, Hayes J, Lee SMC, Lockley SW, Monseur B, Nelson NG, Sargsyan A, Smith SM, Stenger MB, Stepanek J, Zwart SR; Bellagio II Team.

The First Decade of ISS Exercise: Lessons Learned on Expeditions 1-25.

INTRODUCTION: Long-duration spaceflight results in musculoskeletal, cardiorespiratory, and sensorimotor deconditioning. Historically, exercise has been used as a countermeasure to mitigate these deleterious effects that occur as a consequence of microgravity exposures. The International Space Station (ISS) exercise community describes their approaches, biomedical surveillance, and lessons learned in the development of exercise countermeasure modalities and prescriptions for maintaining health and performance among station crews. This report is focused on the first 10 yr of ISS defined as Expeditions 1-25 and includes only crewmembers with missions > 30 d on ISS for all 5 partner agencies (United States, Russia, Europe, Japan, and Canada). All 72 cosmonauts and astronauts participated in the ISS exercise countermeasures program. This Supplement presents a series of papers that provide an overview of the first decade of ISS exercise from a multidisciplinary, multinational perspective to evaluate the initial countermeasure program and record its operational limitations and challenges. In addition, we provide results from standardized medical evaluations before, during, and after each mission. Information presented in this context is intended to describe baseline conditions of the ISS exercise program. This paper offers an introduction to the subsequent series of manuscripts.

Standards for renal biopsies: comparison of inpatient and day care procedures.

There are no national standards for the adequacy and complications of percutaneous renal biopsies. We developed local standards that have been used in a prospective audit of biopsies undertaken in a tertiary pediatric nephrology unit between January 1997 and December 2000. We compared outcomes of biopsies performed on inpatients with day care procedures. A total of 251 biopsies (113 transplant) were undertaken, 114 (46%) as day care procedures. Adequate tissue for diagnosis was obtained in 245 (97.6%), with a standard set at >95%. This was also achieved for a mean number of passes in native (<3 in 80%) and transplanted (<2 in 80%) kidneys. Eleven patients (4%) developed macroscopic hematuria (standard <5%) and none required transfusion. Delay in discharge occurred in 4 patients, and a further 4 returned to the ward post discharge. There was no significant difference in complication rates between inpatient and day care patients. Our local biopsy standards were met in this audit. Such standards could provide useful comparisons between units in national audit programs, as well as permitting the monitoring of individual performance as part of clinical governance. Day care procedures benefit the patient and family, as well as significantly reducing costs.
