In conclusion the number of tumours tumour size BCG

In conclusion, the number of tumours, tumour size, BCG instillation, and intravesical instillation of chemotherapy were found to be independent predictors for time to recurrence after TUR-Bt in Japanese patients with NMIBC. Our novel, simple, and prognostic classification may not only predict the recurrence risk but greatly help to identify indicators for adjuvant intravesical therapy. Given the fact that comparing with advanced LDN 209929 dihydrochloride cancer, NMIBC has only a small breakthrough drug (Brower, 2015), further studies with a more patients in a more diversified cohort are required to validate this risk classification and to enhance the effectiveness of existing treatment for Asian patients with bladder cancer.

Introduction Traumatic brain injury (TBI) is a major cause of death and disability worldwide (Maas et al., 2008), especially in children and young adults. Classical approaches to grading TBI rely on the Glasgow coma score (GCS) (Saatman et al., 2008) and neuroimaging, but this classification takes no account of mechanistic heterogeneity or addresses emerging approaches to precision medicine (Maas et al., 2015). TBI is associated with a complex metabolic disruption that results in energy crisis and energy failure, which is the consequence of multiple mechanisms, including classical ischaemia (Coles et al., 2004), diffusion hypoxia (Menon et al., 2004), mitochondrial dysfunction (Lakshmanan et al., 2010) and increased energy needs (from excitotoxicity, seizure activity and spreading depolarization) (Timofeev et al., 2011). Thus far, the only approaches to examine this metabolic dysregulation have involved the use of cerebrospinal fluid (CSF), brain microdialysis, arteriojugular venous differences, or advanced metabolic imaging with positron emission tomography (PET) or magnetic resonance imaging and spectroscopy (MRIS), none of which are universally available, and are particularly problematic in less severe TBI. Since metabolic dysregulation is such a fundamental facet of TBI pathophysiology, these metabolic changes may contain prognostic information, and early changes may provide a useful summary of the pre-hospital and early hospital physiological insults experienced by the brain. The broad assumption has been that these metabolic changes are the consequence of metabolic failure – but there is the possibility that some may be causes as well as consequences of the pathophysiology observed. In addition, release of brain specific metabolites (i.e. small molecules with molecular mass under 500Da) into the systemic circulation may provide information on blood brain barrier (BBB) dysfunction, a fundamental process in TBI (Saw et al., 2014). Several peptide or protein based biomarkers for TBI have been proposed. These include S100 calcium binding protein B (S100B), neuron-specific enolase, myelin basic protein, creatine kinase brain isoenzyme, glial fibrilary acidic protein, plasma DNA, brain-derived neurotrophic factor, and ubiquitin carboxy-terminal hydrolase-L1 (Berger et al., 2006; Ingebrigtsen and Romner, 2002; Mondello et al., 2011; Papa et al., 2010; Pelinka et al., 2004; Vos et al., 2004). However, most of these biomarkers lack the disease specificity. For example, protein S100B, the most extensively studied biomarker of TBI, has been reported to be released into the serum also after experimental ischemic injury to the liver, kidney, and the gut (Pelinka et al., 2004). Moreover, its levels have been found to have increased also after exercise (Koh and Lee, 2014), extracranial trauma (Savola et al., 2004) and burns (Anderson et al., 2001) and it has also been suggested as a biomarker of melanoma (Torabian and Kashani-Sabet, 2005).

Discussion We found that two medium-chain fatty acids (OA and DA) are elevated in TBI as well as associated with poor outcomes in TBI patients. Medium-chain fatty acids readily penetrate the BBB (Oldendorf, 1973) and there is evidence that FAs can be transported in both directions through the BBB (Spector, 1988). A recent study of free fatty acids in plasma and brain, following intravenous human mesenchymal stem cells transplantation into rats that had undergone transient middle cerebral artery occlusion, showed upregulation of several FAs in both blood and brain, including OA, whereas the levels of long-chain FAs were significantly reduced (Paik et al., 2009). Mitochondria play a crucial role in the pathophysiology and energy crisis associated with the brain injury. OA and DA provoke mitochondrial dysfunction by acting as uncouplers and metabolic inhibitors of the oxidative phosphorylation (Schuck et al., 2009b). Several studies have also shown that DA and OA play a role in brain energy metabolism (Ebert et al., 2003) and elicit lipid and protein oxidative damage (Green and Reed, 1998; Reis de Assis et al., 2004; Schuck et al., 2009a).
