Skeletal changes during and after spaceflight

Vico, Laurence, Hargens, Alan·2018·Nature Reviews Rheumatology

Abstract

Space sojourns are challenging for life. The ability of the human body to adapt to these extreme conditions has been noted since the beginning of human space travel. Skeletal alterations that occur during spaceflight are now better understood owing to tools such as dual-energy X-ray densitometry and high-resolution peripheral quantitative CT, and murine models help researchers to understand cellular and matrix changes that occur in bone and that are difficult to measure in humans. However, questions remain with regard to bone adaptation and osteocyte fate, as well as to interactions of the skeleton with fluid shifts towards the head and with the vascular system. Further investigations into the relationships between the musculoskeletal system, energy metabolism and sensory motor acclimatisation are needed. In this regard, an integrated intervention is required that will address multiple systems simultaneously. Importantly, radiation and isolation-related stresses are gaining increased attention as the prospect of human exploration into deep space draws nearer. Although space is a unique environment, clear parallels exist between the effects of spaceflight, periods of immobilization and ageing, with possibly irreversible features. Space travel offers an opportunity to establish integrated deconditioning and ageing interventions that combine nutritional, physical and pharmaceutical strategies.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
