Traumatic brain injury (TBI) is a major cause of death and disability worldwide, especially in children and young adults. TBI is an example of a medical condition where there are still major lacks in diagnostics and outcome prediction. Here we apply comprehensive metabolic profiling of serum samples from TBI patients and controls in two independent cohorts. The discovery study included 144 TBI patients, with the samples taken at the time of hospitalization. The patients were diagnosed as severe (sTBI; n=22), moderate (moTBI; n=14) or mild TBI (mTBI; n=108) according to Glasgow Coma Scale. The control group (n=28) comprised of acute orthopedic non-brain injuries. The validation study included sTBI (n=23), moTBI (n=7), mTBI (n=37) patients and controls (n=27). We show that two medium-chain fatty acids (decanoic and octanoic acids) and sugar derivatives including 2,3-bisphosphoglyceric acid are strongly associated with severity of TBI, and most of them are also detected at high concentrations in brain microdialysates of TBI patients. Based on metabolite concentrations from TBI patients at the time of hospitalization, an algorithm was developed that accurately predicted the patient outcomes (AUC=0.84 in validation cohort). Addition of the metabolites to the established clinical model (CRASH), comprising clinical and computed tomography data, significantly improved prediction of patient outcomes. The identified 'TBI metabotype' in serum, that may be indicative of disrupted blood-brain barrier, of protective physiological response and altered metabolism due to head trauma, offers a new avenue for the development of diagnostic and prognostic markers of broad spectrum of TBIs.

The RMS is the only truly international microscopical society, drawing distinguished members from all over the world. It also serves the needs of its company members who represent all the major manufacturers and suppliers of microscopes, equipment and services. In addition to this, the Society is pursuing an initiative to encourage young microscope users who may go on to influence microscopy in years to come. The Society is dedicated to advancing science, developing careers and supporting wider understanding of science and microscopy through its Science and Society activities. In support of the above, it publishes The Journal of Microscopy and microscopy handbooks, as well as helping young scientists through bursaries. The Society is incorporated by Royal Charter. Its governing documents are its Charter and By-laws. The most recent AGM minutes, Trustees Report and Accounts are available below - 2007 AGM draft minutes Full 2007 Trustees Report and Accounts - as submitted to the Charity Commission The RMS is a member of: - the Foundation for Science and Technology - the Biosciences Federation - the International Federation of Societies for Microscopy - the European Microscopy Society training opportunities; jobs.
