Background: Spinal cord injury (SCI) is a severe neurological disease leading to poor quality of life. Objectives: The regenerative effect of adipose-derived mesenchymal stem cells (AD-MSCs) encapsulated into fibrin, and collagen hydrogel scaffolds on a rat model of SCI was investigated using clinical and histopathological examinations. Methods: A total of 18 adult male Wistar rats (250 - 300 g) were prepared and randomly divided into three equal groups, each with six rats, including the control or SCI group (SCI contusion model without treatment), SCI contusion model treated with AD-MSCs encapsulated in fibrin hydrogel, and SCI contusion model treated with AD-MSCs encapsulated in collagen hydrogel groups. Clinically, functional recovery or hindlimb locomotor activity was assessed using Basso, Beattie, and Bresnahan's (BBB) scoring system four weeks post-treatment. The rats were sacrificed at week four post-treatment, and their spinal cords were examined histopathologically. Results: Faster functional recovery indicated with hindlimb locomotor activity was seen in both treatment groups compared to the control group. Severe polio and leuko-myelomalacia associated with disruption of spinal cord structure were identified in the control group. Mild polio and leuko-myelomalacia associated with mild to moderate disruption of spinal cord structure were seen in the collagen hydrogel + AD-MSCs and fibrin hydrogel + AD-MSCs groups. Conclusions: AD-MSCs encapsulated into fibrin and collagen hydrogels, as two of the most promising ECM-based or natural scaffolds have the potential to be developed in neural tissue engineering (NTE), such as for the treatment of SCI.

Background: Despite extensive research, the exact molecular mechanisms underlying migraine development and especially its progression and transformation from episodic into chronic is still unknown. Objectives: This study aimed to assess the role of somatosensory cortex and hippocampal transient receptor potential vanilloid 1 (TRPV1) in migraine in a rat model. Methods: This study was an intervention study. Adult male Wistar rats were divided into three groups, including sham, episodic migraine (EM), and chronic migraine (CM). The sham group received normal intraperitoneal (IP) saline injections every two days for 11 days, and the EM group received a single dose of trinitroglycerin (TNG) injection (IP; 10 mg/kg). For the CM group, TNG was administrated every two days (on days 3, 5, 7, 9, and 11; IP; 10 mg/kg). TRPV1 levels in plasma, somatosensory cortex, and hippocampus were detected with an enzyme-linked immunosorbent assay (ELISA) kit. Results: The findings showed that in both CM and EM groups the TRPV1 levels in plasma (P < 0.001 in both groups), somatosensory cortex (P < 0.05 and P < 0.001, respectively), and hippocampus (P < 0.01 in both groups) increased after migraine induction. Interestingly, in the somatosensory cortex, this TRPV1 elevation in the CM group was much greater than the EM group, and a significant difference was observed between the two groups (P < 0.05). Conclusions: Our results suggested that headache severity and frequency may enhance concomitant with the upregulation of somatosensory cortex TRPV1. This new achievement can help to develop new drug approaches to prevent CM.

Background: Cerebral ischemia can cause irreversible structural and functional damages to the brain, especially to the hippocampus. Preconditioning with endurance training and endogenous adenosine infusion may reduce ischemia-associated damages. Objectives: This study aimed to evaluate the effect of preconditioning with endurance training and endogenous adenosine infusion on cell death in the hippocampal CA1 region following ischemia/reperfusion injuries in a rat model. Methods: Male Wistar rats were divided into five groups: (1) control (n = 8); (2) ischemia (n = 12); (3) endurance training + ischemia (n = 12); (4) adenosine infusion + ischemia (n = 12); and (5) endurance training + adenosine infusion + ischemia (n = 12). The rats in the training groups ran on a treadmill five days per week for eight weeks. In the adenosine infusion groups, the rats were injected 0.1 mg/mL/kg of adenosine intraperitoneally. Also, in the ischemic groups, both common carotid arteries were clamped for 45 minutes. Cresyl violet staining and real-time polymerase chain reaction (PCR) assay were used to evaluate cell death and cytokine gene expression, respectively. Results: Based on the present results, treatments, including endurance training + ischemia, adenosine infusion + ischemia, and endurance training + adenosine infusion + ischemia reduced the level of interleukin-6 (IL-6) and glutamate gene expression, respectively, compared to the group of ischemia only. In contrast, the expression of nerve growth factor (NGF) and adenosine receptor (A2A) genes increased by seven, four, and two folds in the endurance training + ischemia, adenosine infusion + ischemia, and endurance training + adenosine infusion + ischemia groups, respectively, compared to the group of ischemia only. Conclusions: Endurance training on a treadmill and exogenous adenosine infusion synergistically diminished cell death and reduced the expression of pro-inflammatory cytokines, while promoting the neurotrophic factor expression. When endurance training and adenosine infusion were used as stimulants before the induction of cerebral ischemia, they significantly reduced cell death.

Background: Myofascial pain syndrome (MPS) is a non-inflammatory disorder with muscle stiffness and pain that occurs with the appearance of palpable and irritating nodules in the muscular system. Stroke is one of the most common neurological diseases that in many cases leads to disability and reduction of quality of life (QOL). Objectives: This study aimed to evaluate the relationship between MPS and physical and mental health (MH) status in patients with stroke. Methods: Using available sampling method, this case-control study included 260 patients with stroke. To collect data, demographic characteristics, Visual Analogue Scale (VAS), 36-item Short Form Survey (SF-36), and Depression, Anxiety and Stress Scale (DASS-21) were used. Data analysis was performed using SPSS 16. Mean and standard deviation were used for descriptive statistics and independent t-test, paired t-test, and analysis of variance (ANOVA) were used for inferential tests. Results: While the pain score was 6.35 (1.39), QOL score was 38.86 (11.69), and MH score was 16.26 (2.75) in the intervention group, these scores were 2.15 (0.96), 63.96 (17.52), and 9.02 (4.63), respectively, in the control group. The results showed no statistically significant relationship between MPS and QOL. But there was a statistically significant relationship between MPS and MH, so that the MH status of patients with MPS was lower than the MH status of other patients. Conclusions: Necessary interventions have been done to improve the health status of patients with MPS, which will lead to an increase in the health status of these patients.

Background: Animal spinal cord injury (SCI) models have provided a better perception of the mechanisms related to traumatic SCI and evaluation of the effectiveness of experimental therapeutic interventions. Objectives: The aim of this study is to develop a cost-effective modified Allen's device to induce contusive spinal cord injury. Methods: Adult male Wistar rats were subjected to contusive spinal cord injury using a customized weight drop model through 10-g weights delivered from a 25-mm height onto an exposed spinal cord. Locomotor and sensory function during 28 days were assessed. Moreover, histopathological changes were assessed at one week and 28 days post SCI. Results: All the SCI rats showed hind limb paralysis up to 48 h post SCI and neuropathic pain after injury. Histological changes similar to the previous reports for contusion model were observed. Conclusions: According to our findings, little variability was observed in the BBB score of individual rats at 28 days after injury. Our customized device to induce spinal cord injury is a simple and inexpensive alternative method to the highly sophisticated contusion device commonly used to induce SCI.

Background: Elderly is one of the most important and critical periods of life, and paying attention to the issues and problems of this period is very important. Objectives: The present study was performed to investigate the relationship between pain and disability in the elderly with dementia in 2021. Methods: In the present cross-sectional descriptive study, 120 elderly people with dementia were included. The instruments used in the four sections were the demographic profile form, the P-APS pain observation tool, and Stanford Disability Questionnaire questions. the researcher identified the elderly with dementia by available sampling method and if the elderly with dementia were eligible and written informed consent was obtained from the elderly and their primary caregivers, the questionnaires were completed. Conditions of pain and disability were described by descriptive tests, and then the relationship between pain and the degree of disability in patients was analyzed by statistical analysis using SPSS16 software. Results: The results showed mean (SD) pain score was 14.45 (4.23), disability score was 12.75 (3.09), and fall score was 37 (30.8%). According to pain score status classification, 4 (3.3%) of the elderly had no pain, 8 (6.7%) had mild pain, 27 (22.5%) had moderate pain, and 81 (67.5%) had severe pain. There is a significant relationship between pain status and disability in the elderly with dementia. By increase in pain, the patients had more disability (P = 0.000, F = 79.971). Conclusions: As the pain increased, the disability of the elderly with dementia decreased. For this reason, preventive interventions are explained in this field.

Background: Brain penetrating blast injury is a leading cause of early death due to excessively elevated intracranial pressure (ICP), culminating in trans-tentorial herniation. The role of craniectomy to decrease ICP and secondary injuries has been controversial particularly in pediatric patients. Three cases of pediatric penetrating blast injuries undergoing decompressive craniectomy are reported in Methods: The current study was a prospective series, including fifteen cases of pediatric blast-related brain injury referred to the emergency ward during a period of two years. Three survived patients had a Glasgow Coma Scale (GCS) of four along with anisocoric pupillary light reflex (PLR). Decompressive craniectomy and ventriculostomy (EVD) were performed. The patients underwent ICP monitoring for two weeks. Results: Early postoperative GCS (5 days) was 7/15 in all three patients. Two weeks and one month’s GCS were 9 and 14, respectively. After three months, cranioplasty was performed. Long-term follow-up detected no major motor deficits after one year and was associated with excellent school performance. Neuroplasticity resulted in contralateral dominancy and handedness in one case. Conclusions: Survivors of pediatric blast brain injury had a favorable outcome after decompressive craniectomy in the current paper. However, there was a limited number of patients, and the results could not be generalized. Further research in this regard with larger sample size is recommended.

Background: Carpal tunnel syndrome (CTS) is the most common focal mononeuropathy. It causes characteristic symptoms, including numbness and paresthesia in hand due to median nerve compression at the wrist. Objectives: We aimed to investigate CTS prevalence and personal, psychosocial, biomedical, and occupational factors related to it comprehensively, according to scattered publications, without the simultaneous evaluation of all CTS risk factors. Methods: A total of 345 patients referred to a hand clinic with a complaint of paresthesia in upper extremities and suspected CTS. The patients underwent neurological assessment and electrodiagnostic (EDX) tests to confirm the diagnosis. The demographic information, past medical history, past trauma history, and occupational history of all the patients were recorded and finally analyzed with SPSS software. Results: Of the patients, 213 (67.1%) met the criteria for CTS, of whom 160 (75%) were female. Females were significantly more affected by CTS than males (P < 0.05). The mean age was higher in the CTS patients (53.80 ± 11.57 years) than in non-patients (42.39 ± 12.31 years, P < 0.001). No statistical relevance was found between CTS prevalence with occupational history, underlying medical conditions, positive Tinel’s and Phalen's tests, and muscle atrophy. Conclusions: We recognized age and gender as main determinants in developing CTS. We also found that older age was related to higher CTS intensity.
