Development and psychometric properties of appraisals of post traumatic spinal cord injury health scale in Iran.

STUDY DESIGN: Development and psychometrics study OBJECTIVE: To evaluate the reliability and validity of a new version of Appraisals of Post-Traumatic Spinal Cord Injury Health Scale (APTSCIHS) in the Persian language for persons with spinal cord injury (SCI). SETTING: The persons were selected from National Spinal Cord Injury Registry of Iran (NSCIR-IR) and Brain and Spinal Cord Injury Research center (BASIR). METHOD: This was a mixed sequential exploratory study that performed in two phases. In the qualitative phase, a systematic scoping review and 12 interviews with the participants were done. Finally, items were generated. In the quantitative phase, face, content, construct and convergent validity were assessed to evaluate validity. To evaluate construct validity, a cross-sectional study was conducted on 305 persons with TSCI along with internal consistency and stability assessments. All quantitative data analyses were conducted using SPSS 22 software. RESULTS: The content validity and reliability were indicated by Scale's Content Validity Ratio (S-CVR) = 0.73 and Scale's Content Validity Index (S-CVI) = 0.86, Cronbach's α = 0.9 and the Test re-test reliability using intra-class correlations were (ICC) = 0.97 to 0.98. Exploratory factor analysis determined eight factors which showed more than 52% of the variance. APTSCIHS had a significant and strong correlation with Appraisals of DisAbility Primary and Secondary Scale (ADAPSS) (r = 0.475, P < 0.001). CONCLUSION: Results showed the 36 items APTSCIHS tool had an acceptable validity and reliability in Iran, and it can help health care providers or even administrators improve the quality of the rehabilitation services and quality of life.

Predictors of Outcome After Surgical Decompression for mild degenerative Cervical Myelopathy -A Systematic Review.

STUDY DESIGN: Systematic Reviews. OBJECTIVES: To investigate predictors of surgical outcomes for mild Degenerative Cervical Myelopathy (DCM) by reviewing all related studies conducted at this point. METHODS: An electronic search was carried out in PubMed, EMBASE, Scopus, and Web of Science until June 23, 2021. Full-text articles reporting surgical outcome predictors of mild DCM cases were eligible. We included studies with mild DCM which was defined as a modified Japanese Orthopaedic Association score of 15 to 17 or a Japanese Orthopaedic Association score of 13 to 16. Independent reviewers screened all the records, and discrepancies between the reviewers were solved in a session with the senior author. For risk of bias assessment, RoB 2 tool was used for randomized clinical trials and ROBINS-I for non-randomized studies. RESULTS: After screening 6 087 manuscripts, only 8 studies met the inclusion criteria. Lower pre-operative mJOA scores and quality-of-life measurement scores were reported by multiple studies to predict better surgical outcomes compared to other groups. High-intensity pre-operative T2 magnetic resonance imaging (MRI) was also reported to predict poor outcomes. Neck pain before intervention resulted in improved patient-reported outcomes. Two studies also reported motor symptoms prior to surgery as outcome predictors. CONCLUSION: Lower quality of life before surgery, neck pain, lower pre-operative mJOA scores, motor symptoms before surgery, female gender, gastrointestinal comorbidities, surgical procedure and surgeon's experience with specific techniques, and high signal intensity of cord in T2 MRI were the surgical outcome predictors reported in the literature. Lower Quality of Life (QoL) score and neck prior to surgery were reported as predictors of the more improved outcome, but high cord signal intensity in T2 MRI was reported as an unfavorable outcome predictor.

A systematic review and meta-analysis of the global epidemiology of pediatric traumatic spinal cord injuries.

Despite being relatively rare, pediatric traumatic spinal cord injury (TSCI) is a debilitating event with high morbidity and long-term damage and dependency. This study aims to provide insight on the epidemiological characteristics of pediatric TSCI worldwide. The studies were included if they provided data for the pediatric population with the diagnosis of TSCI. Information sources included PubMed, Embase, Web of Science, and Scopus. All databases were searched from 1990 to April 2023. The quality of included studies was evaluated by Joanna Briggs Institute Critical Appraisal Tools. The results of the meta-analysis were presented as forest plots. PROSPERO Registration code: CRD42020189757. We identified 87 studies from 18 developed and 11 developing countries. Of the 87 studies evaluated, 52 studies were considered medium quality, 27 studies were considered high quality, and 8 studies were considered low quality. In developed countries, the proportion of TSCIs occurring in patients aged 0-15 years was 3% (95% CI: 2.2%; 3.9%), while in developing countries, it was 4.5% (95% CI: 2.8%; 6.4%). In developed countries, the pooled incidence of pediatric TSCI was 4.3/millions of children aged 0-15/year (95% CI: 3.1; 6.0/millions children aged 0-15/year) and boys comprised 67% (95% CI: 63%; 70%) of cases. The most prevalent level of injury was cervical (50% [95% CI: 41%; 58%]). The frequency of SCI Without Obvious Radiological Abnormality (SCIWORA) was 35% (95% CI: 18%; 54%) among children 0-17 years. The most common etiology in developed countries was transport injuries (50% [95% CI: 42%; 57%]), while in developing countries falls were the leading cause (31% [95% CI: 20%; 42%]). The most important limitation of our study was the heterogeneity of studies in reporting age subgroups that hindered us from age-specific analyses.   Conclusion: Our study provided accurate estimates for the epidemiology of pediatric TSCI. We observed a higher proportion of pediatric TSCI cases in developing countries compared to developed countries. Furthermore, we identified distinct epidemiological characteristics of pediatric TSCI when compared to adult cases and variations between developing and developed countries. Recognizing these unique features allows for the implementation of cost-effective preventive strategies aimed at reducing the incidence and burden of TSCI in children. What is Known: • Pediatric Traumatic Spinal Cord Injury (TSCI) can have profound physical and social consequences for affected children, their families, and society as a whole. • Epidemiological insights are vital for they provide the data and understanding needed to the identification of vulnerable populations, aiding in the development of targeted prevention strategies and effective resource allocation. What is New: • The estimated incidence of pediatric TSCI in developed countries is 4.3 cases per million children aged 0-15. The proportion of pediatric TSCI cases in relation to all-age TSCI cases is 3% in developed countries and 4.5% in developing countries. • The etiology of TSCI in pediatric cases differs between developing and developed countries. In developed countries, transport injuries are the most prevalent cause of pediatric TSCI, while falls are the least common cause. Conversely, in developing countries, falls are the leading cause of pediatric TSCI.

Development of a comprehensive assessment tool to measure the quality of care for individuals with traumatic spinal cord injuries.

OBJECTIVE: To develop a comprehensive assessment tool to evaluate the Quality of Care (QoC) in managing individuals with traumatic spinal cord injuries (TSCI). METHOD: At first, the concepts of QoC for TSCI were identified by conducting a qualitative interview along with re-evaluation of the results of a published scoping review (conceptualization). After operationalization of indicators, they were valued by using the expert panel method. Afterward, the content validity index (CVI) and content validity ratio (CVR) were calculated and served as cut-offs for indicator selection. Then specific questions were developed for each indicator and classified into three categories: pre-hospital, in-hospital, and post-hospital. Data availability of the National Spinal Cord Injury Registry of Iran (NSCIR-IR) was subsequently used to design questions that represent indicators in an assessment tool format. The comprehensiveness of the tool was evaluated using a 4-item Likert scale by the expert panel. RESULT: Twelve experts participated in conceptualization and 11 experts participated in operationalization phase. Overall, 94 concepts for QoC were identified from published scoping review (87 items) and qualitative interviews (7 items). The process of operationalization and indicator selection led to the development of 27 indicators with acceptable content validity. Finally, the assessment tool contained three pre-hospital, twelve in-hospital, nine post-hospital, and three mixed indicators. Ninety-one percent of experts evaluated the entire tool as comprehensive. CONCLUSION: Our study presents a health-related QoC tool that contains a comprehensive set of indicators to assess the QoC for individuals with TSCI. However, this tool should be used in various situations to establish construct validity further.

Cognitive appraisals of disability in persons with traumatic spinal cord injury: a scoping review.

STUDY DESIGN: Scoping review. OBJECTIVES: To describe the meaning of cognitive appraisals, their relation with outcome. measures, and adapted appraisal scales after Spinal Cord Injury (SCI) in the existing literature. METHODS: This review was performed according to the Arksey and O'Malley (2005) framework that consisted of five steps: setting the review question, searching the literature, selecting and classifying the studies, charting the data, and summarizing the results. Published articles from 1990 to 16 May 2020 related to cognitive appraisal, persons with traumatic SCI (TSCI), and persons older than 18 years were identified by searching by key terms in four databases (PubMed, Web of Science, Scopus, and Embase). RESULTS: The included studies (n = 26) were categorized into three categories. Categories focused on the meanings of cognitive appraisals following TSCI (i.e., appraisals being complex and context-related, or in general definition how persons with TSCI interpret their disability and how they evaluate the resources available to respond to it), the relationship between cognitive appraisals and physical/psychological/social/ outcomes, and appraisals of disability (including the use of appraisals as a predictor of subsequent positive or negative consequences). CONCLUSIONS: The results demonstrated that a cognitive appraisal of TSCI is critical to longer-term rehabilitation outcomes. A combination of physical and psychological-based interventions can help to modify negative or dysfunctional appraisals. Cognitive appraisal in TSCI seems to vary from person to person. To predict it and develop a rehabilitation plan, future research needs to focus on the relationship between cognitive appraisal and person-related factors, including demographic characteristics.

Epidemiology of Traumatic Spinal Cord Injury in Developing Countries from 2009 to 2020: A Systematic Review and Meta-Analysis.

INTRODUCTION: Traumatic spinal cord injury (TSCI) is a catastrophic event with a considerable health and economic burden on individuals and countries. This study was performed to update an earlier systematic review and meta-analysis of epidemiological properties of TSCI in developing countries published in 2013. METHODS: Various search methods including online searching in database of EMBASE and PubMed, and hand searching were performed (2012 to May 2020). The keywords "Spinal cord injury," "epidemiology," "incidence," and "prevalence" were used. Based on the definition of developing countries by the International Monetary Fund, studies related to developing countries were included. Data selection was according to PRISMA guidelines. The quality of included studies was evaluated by Joanna Briggs Institute Critical Appraisal Tools. Results of meta-analysis were presented as pooled frequency, and forest, funnel, and drapery plots. RESULTS: We identified 47 studies from 23 developing countries. The pooled incidence of TSCI in developing countries was 22.55/million/year (95% CI: 13.52; 37.62/million/year). Males comprised 80.09% (95% CI: 78.29%; 81.83%) of TSCIs, and under 30 years patients were the most affected age group. Two leading etiologies of TSCIs were motor vehicle crashes (43.18% [95% CI: 37.80%; 48.63%]) and falls (34.24% [95% CI: 29.08%; 39.59%], respectively). The difference among the frequency of complete injury (49.47% [95% CI: 43.11%; 55.84%]) and incomplete injury (50.53% [95% CI: 44.16%; 56.89%]) was insignificant. The difference among frequency of tetraplegia (46.25% [95% CI: 37.78%; 54.83%]) and paraplegia (53.75% [95% CI: 45.17%; 62.22%]) was not statistically significant. The most prevalent level of TSCI was cervical injury (43.42% [95% CI: 37.38%; 49.55%]). CONCLUSION: In developing countries, TSCIs are more common in young adults and males. Motor vehicle crashes and falls are the main etiologies. Understanding epidemiological characteristics of TSCIs could lead to implant-appropriate cost-effective preventive strategies to decrease TSCI incidence and burden.

Prevalence and viral load determination of BK polyomavirus among Iranian patients with brain tumors.

BACKGROUND: Due to persistent infections of human central nervous system (CNS), polyomaviruses have been identified as one of the risk factors for brain tumor development. Human BK virus is of significant interest due to its experimental neuro-oncogenic potential and the possible association with CNS neoplasms. However, the results of different studies are discrepant. In the present study, we aimed to investigate the prevalence of BK virus genome and quantify BK viral load in Iranian patients with primary and metastatic brain malignancies. METHODS: To assess the prevalence of BK virus sequences, a total of 58 fresh brain tumors were examined by quantitative real-time PCR. The BK viral load was determined as viral copy number per cell. RESULTS: Of the 58 brain tumor samples BK tumor antigen (TAg) sequences were detected in 26 (44.8%) of cases. In primary brain tumors, BK virus sequences were recognized more frequently in schwannomas (15.5%) and meningiomas (12.1%). The mean BK virus TAg copy number in positive cases was 0.20×10-3±0.27×10-3 (range 0.01×10-3- 0.8×10-3) copies per cell. CONCLUSION: Taken together, in the present study low copy numbers of BK virus TAg gene was detected in brain tumor cells, which can indicate that BK virus may contribute to tumor induction by indirect mechanisms or neuro-persistence of this virus without any pathological consequences.

Artificial Neural Network for Predicting the Safe Temporary Artery Occlusion Time in Intracranial Aneurysmal Surgery.

BACKGROUND: Temporary artery clipping facilitates safe cerebral aneurysm management, besides a risk for cerebral ischemia. We developed an artificial neural network (ANN) to predict the safe clipping time of temporary artery occlusion (TAO) during intracranial aneurysm surgery. METHOD: We devised a three-layer model to predict the safe clipping time for TAO. We considered age, the diameter of the right and left middle cerebral arteries (MCAs), the diameter of the right and left A1 segment of anterior cerebral arteries (ACAs), the diameter of the anterior communicating artery, mean velocity of flow at the right and left MCAs, and the mean velocity of flow at the right and left ACAs, as well as the Fisher grading scale of brain CT scans as the input values for the model. RESULTS: This study included 125 patients: 105 patients from a retrospective cohort for training the model and 20 patients from a prospective cohort for validating the model. The output of the neural network yielded up to 960 s overall safe clipping time for TAO. The input values with the greatest impact on safe TAO were mean velocity of blood at left MCA and left ACA, and Fisher grading scale of brain CT scan. CONCLUSION: This study presents an axillary framework to improve the accuracy of the estimated safe clipping time interval of temporary artery occlusion in intracranial aneurysm surgery.

Bizhan Aarabi and Knowledge Development in Neurotrauma.

Neurotrauma (NT) is one of the common causes of mortality and morbidity. Investigating the role of people who had an impact on the development of knowledge of NT is reasonable. Our aim is to investigate the role of Bizhan Aarabi, professor of Neurosurgery, on the knowledge development in NT. Accordingly, we searched the Scopus database for Bizhan Aarabi on August 8, 2020 and selected papers with at least 10 citations, investigating his impact on NT and details of his publications. He has published 168 papers including original articles, reviews, conference papers, letters, and editorials according to the Scopus databases. There are 112 papers with 10 or more citations. Thirty-eight out of 112 papers (33.9%) were in the first and the highest rank journal: 29 in Neurosurgery and 9 in the Journal of Neurotrauma. Twenty-four papers have the level of evidence (LOE) of "1". Bizhan Arabi developed knowledge in NT especially in the cervical spine/spinal cord trauma and brain injury and his publications are references for spine/neurosurgeons.

Ethical Considerations for Living in Temporary Shelters (i.e., camps) Following a Natural Disaster.

BACKGROUND: Some disasters, such as earthquake and flood make the majority of affected people homeless. The accommodation of these people in temporary shelters and camps requires some specific ethical issues. The aim of the present study was to discuss ethical issues regarding living in camps following natural disasters. METHODS: This study is conducted utilizinga qualitative content analysis approach. The required data were collected from four Focus Group Discussions (FGDs). Subsequently, 11 in-depth interviews were completed using the individuals who had the experience of receiving care following natural disasters and continued until data saturation. Data were analyzed using Graham content analysis method. RESULTS: According to the results obtained from affected people's views, the most important ethical issues that are not considered important in temporary shelters and camps include:1) the violation of privacy,2) the shortage of basic needs (e.g., food, water, and sanitation) and type and quality of services rendered,3) lack of attention to cultural and religious views of the affected people, 4) cause of evacuation, 5)lack of co-operation among disaster managers, 6)respecting the properties of the affected people, 7)conditions and geographic location of camps, 8)property care, and 9)community-based care. CONCLUSION: Without paying attention to ethical issues, living in temporary shelters (i.e., camps) violates the dignity of affected people and then the affected people will not have appropriate cooperation with the managers. All these issues expose them to more harm than before.

Different Pain States of Trigeminal Neuralgia Make Significant Changes in the Plasma Proteome and Some Biochemical Parameters: a Preliminary Cohort Study.

Trigeminal neuralgia (TN) with chronic and severe neuropathic pain leads to remarkable interference in daily living activities of patients. Unknown molecular mechanisms involved in TN pathophysiology are a challenge for complete treatment of the disease. The present study was conducted to investigate changes in the plasma proteome beside biochemical parameters, including calcitonin gene-related peptide (CGRP), nitric oxide (NO), amino acids, and vitamin D (Vit D) in different pain states in TN patients. Plasma samples were obtained from the control group (#13) and patients with purely paroxysmal type of classical TN (#13) before and after microvascular decompression (MVD). We analyzed plasma proteome using two-dimensional gel electrophoresis (2-DE) and identified altered proteins by applying MALDI-TOF/TOF mass spectrometry. The plasma levels of neurotransmitters (CGRP, NO, and amino acids) and Vit D were investigated by ELISA and liquid chromatography-tandem mass spectrometry (LC-MS/MS). The pain-rating index (PRI) was specified using a McGill pain questionnaire, which indicated a significant pain reduction after MVD. Plasma proteome analysis showed upregulated expression of transthyretin (TTR), retinol-binding protein 4 (RBP4), and alpha-1-acid glycoprotein 2 (AGP2) in TN patients compared to control group; whereas, TTR and RBP expression was downregulated after surgery. Moreover, the elevated NO and CGRP and decreased Vit D concentrations were observed in patients. After surgery, NO, Arg, Cit, and Gly levels were decreased along with pain relief. Our findings support the role of altered proteins in TN pathophysiology and suggest involvement of the evaluated neurotransmitters and Vit D in pain pathway sensitization during the disease.

Ethical Issues in Technological Disaster: A Systematic Review of Literature.

BACKGROUND: Industrialization could bring risk of Technological Disaster (TD) such as happened in Chernobyl, Bhopal and Fukushima crisis. Little has been discussed about its related ethical issues. In this study, we aimed to investigate ethical issues have been stated for technological disasters. METHODS: A systematic search was conducted on the main international literature databases including Pubmed, Embase, Scopus and ISI (Jan 1, 2000 to Jan 1, 2018). From 64articles were eligible for investigation of ethical issues in Natural disaster, 6 was related to Technological Disaster. The articles were in English language. RESULTS: Our result show that there are seven articles discussing ethical issues during Technological disaster. All of them are related to nuclear crisis in Fukushima resulting from Japan tsunami 2011. These articles discussed mainly three ethical issues in providing medical care to victims of Technological Disasters as follow: 1- Duty of care 2- Mandatory evacuationand3- Resource Allocation. CONCLUSION: Victim health is the main factor for making decision and implementation of any programs during response to disasters. Mandatory Evacuation for reasons other than providing health to people (such as: maintain public order) and if bring health risk to people will be unjustified. Duty of health workers for providing care is based on General beneficence meanwhile it is necessary to provide facilities to protect them from dangers that treat them in the field. For act ethically, Health workers must have adequate preparedness for response to T-D meanwhile it is necessary to provide guidelines for individuals that participation in relief operation. It is necessary to discuss more about Technological Disaster Ethics especially in industrial countries and where there is especial industrial with potential of huge crises.

Two times of trigeminal neuralgia resolution following hydrocephalus treatment in a patient with a high-voltage electric shock to his head: a case report and a review of the literature.

Hydrocephalus has rarely been reported to be associated with trigeminal neuralgia. Here we report for the first time a case of trigeminal neuralgia associated with hydrocephalus, whose symptoms completely resolved twice after ventriculoperitoneal shunting. The patient had a high-voltage electric shock to his head, which has not been reported in a patient with ventriculoperitoneal shunt to the best of our knowledge. The possible underlying mechanism of this situation is discussed in addition to a brief review of the literature.

Is the pattern of dietary amino acids intake associated with serum lipid profile and blood pressure among individuals with spinal cord injury?

OBJECTIVE: The probable effect of dietary amino acids intake pattern on serum lipid profile and blood pressure (BP) have not yet been described among individuals with spinal cord injury (SCI). DESIGN: Cross-sectional. SETTING: Tertiary rehabilitation center. PARTICIPANTS: People with SCI referred to Brain and Spinal Cord Injury Research Center between 2011 and 2014. OUTCOME MEASURES: Dietary intakes were assessed by recording consumed foods by 24-hour dietary recall interviews using Nutritionist IV 3.5.3 modified for Iranian foods. Partial correlation test with adjustment for age, weight, body mass index, total energy intake, total fat, cholesterol and carbohydrate intake, and injury-related variables was used. RESULTS: Dietary intake of lysine was positively related to levels of fasting plasma glucose (FPG), triglyceride (TG), systolic blood pressure (SBP) and diastolic blood pressure (DBP) (P < 0.0001, 0.046, 0.002 and 0.009, respectively). There was a positive significant relationship between the intake of cysteine and levels of TG and SBP as well (P : 0.027 and 0.048, respectively). Higher intakes of threonine and leucine had a negative relationship with TG level (P : 0.001 and 0.026, respectively). Furthermore, tyrosine, threonine and leucine were inversely correlated to blood pressure. Total cholesterol level was only related to intake of threonine and leucine (P : 0.004 and 0.012, respectively). FPG was positively associated with intake of all amino acids except for cysteine, glutamic acid, threonine, leucine and histidine. CONCLUSION: In the present study, the pattern of relationships between dietary intake of amino acids and serum lipid profile and BP has been described among people with SCI.

Psychological defense mechanisms among individuals with SCI with adjustment disorder.

OBJECTIVES: The used psychological defense styles among individuals with spinal cord injury (SCI) with adjustment disorders (AJD) have not yet been described. In the present investigation, the prevalence of AJD among people with SCI has been estimated and the pattern of used defense styles has been identified. DESIGN: Cross-sectional investigation. SETTING: A tertiary rehabilitation center in Iran. PARTICIPANTS: Individuals referred to Brain and Spinal Cord Injury Research Center were invited to participate in a screening interview. AJD was diagnosed based on DSM-V criteria. Those with AJD diagnosis were scheduled for another interview to assess defense mechanisms. OUTCOME MEASURES: Demographic and injury-related variables were recorded. Defense mechanisms were assessed by the 40-item version of the Defense-Style Questionnaire (DSQ-40). RESULTS: Among 114 participants, 32 (28%) were diagnosed with AJD among whom 23 subjects attended the second interview. Mean age and time since injury were 29.57 ± 9.29 years and 11.70 ± 6.34 months, respectively. The majority of patients were using idealization defense mechanism (91.3%). In the second and third place, passive aggression (87.0%) and somatization (82.6%) defense mechanisms were observed, respectively. Neurotic style was dominantly used (11.52 ± 2.26). Sex, marital status, educational level, cause of the injury and injury level were not related to defense style (P: 0.38, 0.69, 0.88, 0.73, and P: 0.32, respectively). CONCLUSION: Prevalence of AJD is estimated to be 28% among individuals with SCI. The most prevalent defense style was neurotic and the dominant used defense mechanism was "idealization." The role of demographic and injury-related variables in determining the used defense mechanisms was insignificant.

C-reactive protein as an available biomarker determining mental component of health-related quality of life among individuals with spinal cord injury.

OBJECTIVES: C-reactive protein (CRP) has been shown to correlate with health-related quality of life (HRQL) in some chronic medical conditions. However, these associations have not yet described in spinal cord injury (SCI). In this study, we tried to identify biomarkers associated with HRQL in SCI. DESIGN: Cross-sectional. SETTING: Tertiary rehabilitation center. PARTICIPANTS: Referred patients to Brain and Spinal Cord Injury Research Center between November 2010 and April 2013. OUTCOME MEASURE: Blood samples were taken to measure circulatory CRP, leptin, adiponectin, ferritin, parathyroid hormone, calcitonin, thyroid hormones, fasting plasma glucose and lipid profile. All the analyses were performed with adjustment for injury-related confounders (level of injury, injury completeness and time since injury) and demographic characteristics. HRQL was measured with Short Form health survey (SF-36). RESULTS: The initial inverse association between CRP and total score of SF-36 (P: 0.006, r = -0.28) was lost after adjustment for confounders. However, the negative correlation between CRP and Mental Component Summary (MCS) remained significant (P: 0.0005, r = -0.38). Leptin level was inversely correlated with Physical Component Summary (PCS) (P: 0.02, r = -0.30). CONCLUSION: Although CRP and leptin levels were not related with total scores of SF-36 questionnaire, CRP can be more useful in determining mental component of HRQL whereas leptin can be a determinant of physical component. The combined consideration of these two biomarkers may help to predict HRQL in individuals with SCI.

The correlation between dietary fat intake and blood pressure among people with spinal cord injury.

BACKGROUND: Studies have demonstrated the effect of different dietary fats on blood pressure (BP) in general population. However, these associations have not yet been described in people with spinal cord injury (SCI). METHODS: Referred patients to Brain and SCI Research Center between 2011 and 2014 have been invited to participate. Only paraplegic individuals were recruited and patients with injury at cervical or higher thoracic sections were excluded to omit the bias effect of autonomic dysreflexia. Dietary intakes were assessed by recording consumed foods by 24-hour dietary recall interviews using Nutritionist IV 3.5.3 modified for Iranian foods. Systolic BP (SBP) and diastolic BP (DBP) were measured 3 times and the mean values entered analysis. RESULTS: Higher intakes of cholesterol were related to higher BP (P = 0.010 and 0.011 for SBP and DBP, respectively). Similarly, intake of saturated fat was positively correlated to both SBP (P = 0.016, r = 0.21) and DBP (P = 0.011, r = 0.22). The effect of eicosapentaenoic acid (EPA) on BP was insignificant (P = 0.760 and 0.720 for SBP and DBP, respectively). However, intake of docosahexaenoic acid (DHA) was related to lower BP among people with SCI. CONCLUSION: This study has demonstrated that higher intakes of cholesterol and saturated fat are associated with increased BP, whereas DHA is an antihypertensive agent. Dietary modifications with reduction of cholesterol and saturated fat along with intake of additional DHA supplements may help to reduce BP in spinal cord injured-individuals with hypertension.

Adaptation of Traumatic Brain Injury Guidelines in Iran.

CONTEXT: The National institute for health and care excellence (NICE) and scottish intercollegiate guidelines network (SIGN) are two well-known sources of clinical guideline development. In the past years, they have developed clinical guidelines for the management of head injury. In this report, we will highlight our modifications to these guidelines according to the domestic situation in a developing country. EVIDENCE ACQUISITION: The guidelines were appraised using the appraisal of guidelines for research and evaluation (AGREE) instrument. All key recommendations were reviewed by 14 prominent Iranian neurosurgeons; levels of evidence were evaluated and items with limited evidence were determined. Available evidence for selected items were reviewed and discussed. RESULTS: The following items were the most challenging when accounting for the domestic situation in Iran: age as a risk factor for referral, computed tomography scan, the impact of medical comorbidities, pregnancy, consultation, referral to a neurosurgical unit, and teleconsulting and observation before discharge. CONCLUSIONS: The evidence in the discussed topics was limited and controversial. This report is important because it exposes the current knowledge gap in head trauma studies in Iran.
