Magnetic resonance spectroscopy (MRS) is an imaging technique that provides spectroscopic information about the changes of biological markers. Studies suggest that MRS can be helpful in the prognosis of patients with diffuse axonal injury (DAI)Methods: PubMed and Scopus as two major database were systematically searched in June 2015 by using following search strategy ((((Magnetic resonance spectroscopy OR MRS OR MR spectroscopy)) AND (Diffuse axonal injury OR DAI)) AND Prognosis) to find relevant articles in which the prognostic value of MRS had been investigated in patients with traumatic DAI. All necessary information were extracted and used for data synthesis based on the main purpose of this study. Of total 19 articles found in PubMed and 151 found in Scopus, 8 documents were selected for data extraction in several steps of article selection according to inclusion/exclusion criteria. Total number of patients participated in the selected documents was 197. All of the selected documents showed that MRS can be used for quantitative analysis of metabolite changes in patients with DAI.Discussion: The results of studies show that MRS imaging as a sensitive method can quantitatively determine even small variation of metabolites. Since any changes in metabolite level of the brain after traumatic injury may be useful in the prediction of patient’s outcome; therefore, if such sensitivity of MRS is proven, this method can have prognostic value in patients with DAI. Based on the concluded results of included articles, MRS as a sensitive tools is helpful in the prognosis of patients with DAI.

Introduction: Magnetic resonance spectroscopy (MRS) is an imaging technique that provides spectroscopic information about changes in biological markers. Studies suggest that MRS can be helpful in determining the prognosis of patients with diffuse axonal injury (DAI).Methods: The PubMed and Scopus databases were systematically searched in June 2015 using following search strategy: (“Magnetic resonance spectroscopy” OR MRS OR “MR spectroscopy”) AND [(“Diffuse axonal injury” OR DAI] AND Prognosis) to find relevant articles in which the prognostic value of MRS had been investigated in patients with traumatic DAI. All relevant information was extracted from the identified articles and used to synthesize the data for the purpose of this study.Result: In total, 19 articles were found in PubMed and 151 in Scopus. Of these, eight documents were selected for further data extraction following the application of the inclusion/exclusion criteria. The total number of patients who participated in the research studies described in the selected documents was 197. All of the selected documents showed that MRS can be used to quantitatively assess metabolite changes in patients with DAI.Discussion: The results of the studies indicate that MRS imaging as a sensitive method can quantitatively determine even small variations in metabolites. Any changes in the metabolite level of the brain after traumatic injury may be a useful predictor of a patient’s outcome; therefore, if the sensitivity of MRS is proven, this method can have prognostic value when employed with patients with DAI.Conclusion: Based on the results of this systematic review, MRS is a sensitive tool that is helpful in determining the prognosis of patients with DAI.

Introduction: Previous studies have indicated that administering erythropoietin (EPO) can have a beneficial impact on the clinical outcomes of patients with severe traumatic brain injury (TBI). This review examines the possible therapeutic effects EPO can have neuronal functions, neurological performance, and neurological recovery. Methods: The PubMed and Scopus databases were systematically searched on the 5th June, 2015, using the following search strategy: (“traumatic brain injury” OR “brain trauma”) AND (erythropoietin OR EPO) to identify relevant articles in which the effect of erythropoietin on patients with TBI was assessed. No time limitation was defined as the inclusion criteria. All available studies were extracted and categorized based on the purpose of this study.Result: Of the 908 articles in total that were identified during the initial database search, 901 documents were excluded from further examination because they did not meet the predefined inclusion/exclusion criteria. The total number of patients enrolled in the selected literature was 798. Of these, the use of EPO failed to show significant improvement in 113 patients.Discussion: Previous studies have shown that EPO may represent a valuable neuroprotectant that is useful in the treatment of neonatal brain injury, neurodegeneration, and TBI. Studies on animal TBI models have also found that recombinant human erythropoietin (rhEPO) reduces the development of post-traumatic brain edema.Conclusion: EPO may represent a potential therapeutic approach for the treatment of TBI. In addition, it can improve the patients› recovery prospects and reduce in-hospital mortality and morbidity.
