Abstract
Background: The Electronic Health Record contains personalized health care information. Several factors affect the quality of SEPAS (Iranian electronic health record) data, disregarding the types of hospital information system set-up in hospitals. The purpose of this study was to investigate users' views on the factors affecting the data quality of Iranian Electronic Health Record (SEPAS) in hospitals affiliated to Mashhad University of Medical Sciences.
Methods: This descriptive cross-sectional study was conducted in 2018. In this study, the views of supervisors of the SEPAS system, HIS chief officers, and head of health information technology departments of hospitals were evaluated through a valid and reliable researcher-made questionnaire. Content validity ratio and content validity index of the questionnaire were validated as 0.82 and 0.94, respectively. Furthermore, the internal questionnaire reliability was affirmed by Cronbach's alpha of 0.96. Data analysis was conducted using descriptive statistics in the SPSS v.16 software.
|
Results: The most important individual factor of affecting SEPAS data quality was staff training (4.19±0.94 of 5). Moreover, the factor “Personnel awareness of goal, mission, and vision of SEPAS system" had the lowest score (3.86±1.16). Also, the most critical organizational factor was the integration and relation of the HIS with the Civil Status Registration System (4.43±0.72). In examining technical factors, the quality of its support team responsiveness to user demands had the highest score (4.56±0.58). Also, the utilization of new data collection instruments and technologies (barcode, RFID, etc.) had the lowest score (4.22±0.98).
Conclusion: The most efficient solutions to improve quality of SEPAS data seems to be continuous training of staff, enhancing HIS connection with the Civil Status Registration System and improving the responsiveness of SEPAS support team.

Abstract
Background: The endocannabinoid system interacts with the vanilloid and opioid systems. The current study aims to investigate the effects of the extract obtained from the heated
Cannabis Sativa female flower base either with capsaicin at the spinal cord level or naloxone at the systemic level on the intensity of chemical and thermal pain sensation.
Methods: This experimental study was performed in the Department of Biology at Ferdowsi University of Mashhad from April 2014 to March 2015 using adult male Wistar rats (200-250 g) categorized into groups of 7 animals. In addition to the control and sham (solvent of chemicals) groups, groups with intraperitoneal administration of 50 mg/kg of the hydroalcoholic extract, 2 mg/kg of naloxone alone and naloxone together with extract were investigated. Moreover, intrathecal administration groups including the concentration of 0.01 mg/ 10 μl of extract, the concentration of 0.002 mg/10 μl of capsaicin alone and the extract together with capsaicin were evaluated. To measure the thermal pain threshold, a tail-flick test was used and to measure the chemical pain intensity, the formalin test was utilized. The obtained data were analyzed statically.
Results: Intrathecal administration of the extract together with capsaicin led to a significant reduction of thermal hyperalgesia (P<0.001) and chemical hyperalgesia (P<0.001) induced by intrathecal administration of capsaicin. On the other hand, intraperitoneal administration of naloxone together with the extract did not effect on the thermal pain threshold. While the administration of naloxone increased the severity of chemical pain during the acute phase compared to the group treated with the extract alone (P<0.01).
Conclusion: The phytocannabinoids of the flower extract may have inhibited capsaicin-induced hyperalgesia via cannabinoid receptors activation and the TRPV1 receptor desensitization. Naloxone administration has also been able to attenuate the analgesic effect of hydroalcoholic flower extract during the acute phase of chemical pain. Probably the extract is thought to exert part of its effect on pain through opioid receptors. |

Abstract
Life expectancy has increased throughout the world and, as a result, the population of the elderly is also rising. From the age of 30 years old, the human body mass loses about 0.1 to 0.5% of its skeletal muscle mass annually, which is accelerated after the age of 65 years old. Aging is characterized by a decrease in the progression of musculoskeletal and physical activity known as sarcopenia. Sarcopenia has a complex molecular pathogenesis that includes age-related changes in muscles’ neuromuscular activity, muscle protein replacement, the hormone levels and the related sensitivity of human body to these mentioned factors. The pathogenic conditions and other disorders in sarcopenia are the chronic inflammatory states that include oxidative stress and changes in behavioral factors, especially in nutritional status and physical activity. By definition of the European Working Group on Sarcopenia in Older People (EWGSOP), the diagnosis of sarcopenia is determined by the presence of two main factors which are low muscle mass and low muscle function. Besides, specific sarcopenia-related biomarkers have been identified for early diagnosis and accurate identification of the main pathophysiology mechanisms involved in the development of the disease. Since sarcopenia has adverse outcomes on public health in terms of behavioral factors, frailty, hospitalization and mortality of people, it is an important necessity for the social health system to plan some therapeutic approaches to prevention. The main and more important of these therapeutic approaches have known as exercises, nutritional supplements and hormonal therapies. Also, other new therapeutic strategies are under investigation to be introduced in the future. However, currently, it has been shown that only physical exercise has a positive effect on the controlling and prevention of sarcopenia and its adverse effects on human and public health. However, the role of appropriate nutrition is also effective. Therefore, carefully designed studies in terms of better utilization of physical activity are needed to achieve useful therapeutic results for sarcopenia management. Thus, this survey aims to review the other considerable studies on the pathogenesis, appropriate evaluation of the disease and treatment options for sarcopenia.

Abstract
Background: One of the most empirical subjects particularly in substantial operations for example in surgeries involving the vertebral column, are the implication of sedatives in a manner which would create the least complications such as changes in the hemodynamic parameters. Two such drugs that are widely used in this capacity in clinical settings are midazolam and dexmedetomidine. Hemodynamic stability is particularly important in surgical operations, especially during spinal surgery. One of the ways to prevent hemodynamic changes during surgery is the use of drugs such as midazolam and dexmedetomidine.
Methods: This double-blind randomized clinical trial recruited 105 patients undergoing laminectomy spinal surgery under spinal anesthesia at Al-Zahra Hospital, Isfahan between 21 April 2019 till 1 September 2019. Patients were randomly divided into 3 groups: First was the midazolam group, second the dexmedetomidine group and the third was the control group. Data were presented as mean±standard deviation and percentages. In order for the evaluation of differences to be performed between all groups, an evaluation using the one-way analysis of variance was utilized. Statistical analysis was done by means of the SPSS software version 23 (IBM Corporation, Armonk, New York, USA). The P-value which was accepted as significant was P less than 0.05. (P<0.05)
|
Results: There differences in age and gender were not statistically significant among the studied groups (p>0.05). Results from the ANOVA test showed that the effects when taking into consideration time (P<0.001) and group (P<0.001) were statistically significant on Mean of Arterial Pressure, Systole Blood Pressure and Diastole Blood Pressure. However, Heart Rate and oxygen saturation (SPO2) were not significantly different inter-group as well as intra-group over time (before, during, and after the operation) (P=0.12). Furthermore, the mean of the hemorrhage amount and duration of recovery stay had significant differences over time between all three groups (P<0.05).
Conclusion: The incidence of complications during surgery in the dexmedetomidine group was less than the midazolam group. Additionally, the frequency of complications in the subjects given midazolam was higher than the dexmedetomidine group during recovery.

Abstract
Background: Prostate cancer is the most common malignancy in men and the second leading cause of death in all countries of the world. The exact mechanism of prostate cancer is not known. On the other hand, early detection of prostate cancer can lead to a complete cure. Several clinical experiments including Digital Rectum Examination (DRE), biochemistry such as Prostate Specific Antigen (PSA), and pathology such as Trans Rectal Ultra Sonography (TRUS) are used to assess the size and spread of prostate cancer. In this study, the relationship between mean serum PSA and Gleason score as a standard method in patients with prostate cancer was compared using the parameters extracted from DCE MRI.
|
Methods: This applied-fundamental study was performed on 90 patients with prostate cancer, according to McDonald's criteria who were referred to Shafa Imaging Center in Isfahan, from March 2020 to October 2020. Quantitative analysis is based on modeling the change of concentration of the contrast agent using pharmacokinetic modeling techniques. The pathologist then determined the Gleason score using anatomical landmarks (such as prostate urethra) in the same areas suspected of being cancerous. Existing commercial software captures DCE-MRI data and creates parametric maps such as Ktrans and Kep maps that can be used for diagnostic purposes.
Results: Kep and Ktrans maps showed a significant difference between healthy and cancerous tissue. Kep and Ktrans in prostate cancer were significantly higher than in healthy tissue (P<0.05). Pearson correlation coefficient was used to investigate the relationship between DCE-MRI parameters and histopathological findings. No significant relationship was observed between Gleason score and DCE MRI parameters.
Conclusion: DCE MRI parameters significantly improve the accurate diagnosis of prostate cancer and are useful and effective for diagnosis, management, and evaluation of men with prostate cancer, but should not be considered as a substitute for tissue biopsy.

Abstract
Background: Asthma is the most prevalent chronic disease in childhood and has been growing globally over the last three decades. Studies in this regard indicate different and irrelevant results in Iran. Different prevalence of asthma has been reported in industrialized countries, prevalence of 25.9% in the United Kingdom, 12.8% in Spain and 31% in Australia. This study aimed to evaluate asthma in Iranian children through systematic review and meta-analysis.
Methods: This study was performed as a systematic review and meta-analysis from January 2001 to December 2018. Related articles to the reviewed subject were obtained through searches of Scopus, ScienceDirect, Magiran, SID, Medline (PubMed), and Google Scholar databases. Cross-sectional studies were selected for inclusion in the study and observational studies as well as review studies were excluded from the study. Searches on Google search engine and the inspection of sites related to the topic were also incorporated to examine the grays literature. Duplicate articles and articles that were similar and obtained from the same source were removed through the EndNote software. The total number of articles was 896. Subsequently, the number of articles and studies that met the requirements of the first stage was 274. Ultimately after the elimination of 236 irrelevant articles and the elimination of 5 articles in the secondary examination, eventually 33 articles were added to the final stage. By the I2 index, the heterogeneity of the studies was investigated and reported.
|
Results: In a survey of 33 studies and 97205 participants in the age range of (3-18) years, the general prevalence of asthma in this study based on meta-analysis was 5.1% (CI95%: 4-6.5%). The highest prevalence of asthma was among children from Babol which was 19% (CI95%: 17.8% -20.3%) in 2014 and the lowest prevalence of asthma was among children from Isfahan with 0.7% of prevalence (CI95%: 0.5-1.1) in 2001. Also, with the increase of research years and overall sample size in each study, asthma in children shows increasing and decreasing levels, respectively; and the differences were statistically significant.
Conclusion: Based on what was reported in this study, the prevalence of asthma among Iranian children is lower compared to children of developed countries.

Abstract
Background: Examining the course of changes in predictive indicators of future diabetes, such as blood sugar in high-risk individuals including pre-diabetic patients, can provide valuable information about the incidence of diabetes in these individuals. This study aimed to classify people at risk (pre-diabetes) based on the course of changes in their blood sugar and blood lipid and to investigate the incidence of diabetes in these classes on a sample of patients who were referred to the Endocrine and Metabolism Research Center of Isfahan.
Methods: This cohort study was performed based on the information of the Isfahan Diabetes Prevention Plan (IDPs). This project was implemented from April 2004 to March 2018 in the clinics of the Endocrine and Metabolism Research Center of Isfahan. The subjects in this study include 1228 pre-diabetic patients who participated in this project. Demographic and clinical variables of patients including blood sugar and lipid-blood variables were obtained using a questionnaire and laboratory measurements. Also in this study, the number of clinical variables was recorded 3 times. Data analysis was performed using the latent class growth trees model in R software version v4. (R v4.1.0)
Results: The mean (standard deviation) age of participants was 44 (6.86) years. Subjects were classified into two classes of low-risk impaired blood sugar (n=1165) and high-risk impaired blood sugar (n=63) based on the trend of changes in blood sugar levels. Blood sugar levels were reported in the first class (104.28) and the second class (132.41).
Conclusion: In the present study, it was concluded that there is a significant relationship between the incidence of diabetes and the different classes formed based on the course of changes in blood sugar of at-risk individuals. Therefore, by classifying people at risk, the incidence of this disease can be predicted and thus prevented. Also,measures such as managing the blood sugar and lifestyle variables of pre-diabetic patients through nutrition counseling classes and regular periodic tests can be used to reduce the incidence of diabetes in the future is used in people with pre-diabetes who are at high risk for the disease. |

Abstract
Background: The clinical field has vast sick data that has not been analyzed. Discovering a way to analyze this raw data and turn it into an information treasure can save many lives. Using data mining methods is an efficient way to analyze this large amount of raw data. It can predict the future with accurate knowledge of the past, providing new insights into disease diagnosis and prevention. Several data mining methods exist but finding a suitable one is very important. Today, coronavirus disease (COVID-19) has become one of the causing deadly diseases in the world. The early diagnosis of pandemic coronavirus disease has a significant impact in preventing death. This study aims to extract the key indications of the disease and find the best data mining methods that enhance the accuracy of coronavirus disease diagnosis.
Methods: In this study, to obtain high accuracy in diagnosing COVID-19 disease, a complete and effective workflow over data mining methods was proposed, which includes these steps: data pre-analyzing, indication selection, model creation, the measure of performance, and display of results. Data and related indications of patients with COVID-19 were collected from Kerman Afzalipour Hospital and Rafsanjan, Ali Ebn Abi Taleb Hospital. Prediction structures were made and tested via different combinations of the disease indications and seven data mining methods. To discover the best key indications, three criteria including accuracy, validation and F-value were applied and to discover the best data mining methods, accuracy and validation criteria were considered. For each data mining method, the criteria were measured independently and all results were reported for analysis. Finally, the best key indications and data mining methods that can diagnose COVID-19 disease with high accuracy were extracted.
|
Results: 9 key indications and 3 data mining methods were obtained. Experimental results show that the discovered key indications and the best-operating data mining method (i.e. SVM) attain an accuracy of 83.19% for the diagnosis of coronavirus disease.
Conclusion: Due to key indications and data mining methods obtained from this study, it is possible to use this method to diagnose coronavirus disease in different people of different clinical indications with high accuracy.

Background: Parkinson's disease is one of the chronic neurological diseases. It is the second most common neurodegenerative disease after Alzheimer's, affecting 7.5 million people worldwide and its rate is expected to increase by 20% by 2020. three symptoms of tremor, muscle stiffness and movement disorders are among the main diagnostic symptoms of the disease. The prevalence of Parkinson's worldwide varies between 18 and 418 cases per 100,000 people per year. It is generally estimated that the prevalence of this disease in the general population is 0.3%. A systematic review study was performed to determine the factors associated with Parkinson's disease.
Methods: This study was a systematic review that was conducted by searching national and international databases until February 2020. Initially, all articles which had mentioned Parkinson-related factors were collected and accepted by researchers based on studies. Entry and exit criteria were met. Exclusion criteria included irrelevant items, duplication of studies, unclear procedure, and lack of access to the full text of the study. To reduce bias, articles were evaluated independently by two researchers, and the quality of articles was assessed using the STROBE checklist. All final articles submitted to the systematic review process were prepared by a template checklist. Checklists included article title, first author’s name, year of publication, place of study, risk factors, protective factors, and ineffective factors or the ones which their effects have not yet been determined, and the average age.
Results: In these studies, the following risk factors were reported: family history, agricultural occupation, literacy, stress, well water consumption, aging, environmental factors, genetic factors, pesticide exposure, and alcohol abuse. On the other hand, factors such as smoking and oilseeds, high levels of B-complex vitamins, female estrogen hormones, and selenium have been reported to protect against Parkinson's disease.
Conclusion: Considering the results of the present study and although there is no definitive treatment for this disease, protective factors and risk factors should be seriously considered by health policymakers for preventive measures.

Abstract
Background: Trauma is one of the most common causes of death in all ages. Considering the prevalence of trauma in the general population, and its costs and complications, it is important to use aiding tools to accelerate the diagnosis in order to act in time. The aim of this study was to evaluate the efficacy of ultrasound in diagnosing nerve and tendon injuries in the upper extremities.
Methods: This study is a cross-sectional study, which was carried out at the emergency department of the Besat Hospital, Tehran from march 2018 to march 2019. The statistical population was all patients who had been referred with deep lacerations in upper extremities and had injuries in the superficial or deep compartments (nerves/ tendons). For all the patients who met the inclusion criteria, bedside sonography with 11 Mhz Linear probe was performed by the researcher and under the supervision of the radiologist. The results were compared with the results from local exploration of the wounds. Local exploration of the wounds was also done under the surgeon's supervision. After completing the sample size and data collection, SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) was used for statistical analysis
|
Results: In this study, from 144 patients with penetrating trauma in the upper extremities, 56 patients were suspected with nerve injuries and 50 patients were suspected with tendon injuries. After evaluation with an ultrasound probe, 21 out of 23 cases suspected of nerve injuries were confirmed by local exploration. Local exploration confirmed that 27 out of 28 cases were suspected of tendon injuries. The accuracy of ultrasound in the assessment of nerve damage was estimated at 99.64% and in tendon damage at 92%, and the sensitivity of ultrasound in the diagnosis of nerve damage was 91.30% and in the diagnosis of tendon damage was 96.42%.
Conclusion: By the results of this research it can be concluded, that ultrasound leads to a faster diagnosis. It provides a wider field of view, can reduce possible secondary injuries and increases the accuracy of the diagnosis.

Abstract
Background: In addition to heart disease, ECG also changes in non-heart disease, which due to its similarity, can lead to misdiagnosis of heart disease in patients. ECG changes in brain lesions such as ischemic and hemorrhagic strokes, brain traumas, etc. and have been studied in many articles, but the effects of brain midline shift on ECG changes have not been studied. In this study, we want to examine these changes.
Methods: This is a prospective cross-sectional descriptive study. Patients with brain tumors who were referred to Al-Zahra and Kashani hospitals in Isfahan from April 2019 to March 2021 were selected. Patients with a history of heart disease, patients receiving medications that cause ECG changes, patients with ECG changes due to non-cardiac and cerebral causes, and individuals under 15 years of age were not included in the study. Patients whose ECG changes were due to electrolyte disturbances or acute heart problems were also excluded from the study. After obtaining informed consent from patients, a CT scan or brain MRI was taken and patients were divided into two groups with and without midline shift. Then the ECG was taken and ECG changes (T wave, ST segment, QTc Interval, QRS prolongation) were compared in two groups of brain tumors with and without midline shift.
Results: 136 patients were included in the study. Of these, 69 patients were in the without midline shift group and 67 patients were in the midline shift group. In the midline shift group, 3% of patients had ST segment changes and 23.9% had T wave changes, which were 1.4% and 10.1% in the without midline shift group, respectively. The mean QTc Interval in the two groups without and with midline shift was 338.26 (4 28.438) and 388.66 (37.855), respectively, and the mean QRS in the without midline shift group was 86.09 (88.9.88) ms and in the midline shift group was 94.63 (±12.83) ms.
Conclusion: Brain midline shifts can cause QRS widening, QTc interval prolongation, and T-wave changes in patients' ECGs.

Abstract
Background: Chronic low back pain (CLBP) is one of the most common spine disorders, which is seen in 65-80% of people. Knowing the normal patterns of spine and pelvic parameters is very helpful in determining the susceptible subjects for CLBP.
Methods: This study was conducted in healthy people during April 2017 until April 2018 in Golestan hospital of Ahvaz. Inclusion criteria include; Age group 20-65 years, no history of surgery, spine disorders, and having normal radiographs were performed. People who have complained of back pain in the last three months, neuromuscular disease, lumbosacral anomalies, kyphosis and obvious scoliosis, history of spine surgery and vertebral fracture, were excluded. A 36-inch radiology stereotype was prepared in the standing position. Pelvic and spine parameters that were investigated in this research included the following, Pelvic incidence, Pelvic tilt, Sagittal Vertical Axis, T9 Sagittal Angle, Thoracic Kyphosis, Lumbar Lordosis, and Sacral Slope. All data were analyzed with SPSS software, version 24 (SPSS Inc., Chicago, IL, USA).
|
Results: 50 participants including 27(54%) men and 23(46%) women with an average age of 33±12.5 years and BMI of 25±5.5 kg/m2 were examined. After examining the vertebral and pelvic parameters, it was found that PI is significantly higher in women than in men (P=0.02). It was also found that with increasing age, the amount of Pelvic incidence also increases (P=0.043), so that in people over 60 years of age, the amount of pelvic incidence is significantly higher than other people (P<0.05). Further analyzes showed that BMI has a direct effect on the amount of Thoracic Kyphosis (P=0.03) and Lumbar Lordosis (P=0.04). Thus, the highest amount of Lumbar Lordosis and Thoracic Kyphosis was seen in people with BMI 30-34.9 Kg/m2.
Conclusion: The findings of the present study showed that spine and pelvis indices have an important effect on the occurrence of CLBP. Hence, it is highly recommended to check these parameters in asymptomatic people, especially in older people.

Abstract
Background: According to numerous research related to learning styles and also the difference of these styles in students, this study was designed in order to determine the status of learning styles in medical students in Iran.
Methods: This study was conducted as a systematic review and meta-analysis. Searching for articles in this study was done from September 24 to October 15, 2022 in databases: Proquest, PubMed, Iran medex, Scopus, Sid, Magiran, Google Scholar, Eric and medical education journals. The research environment of Iran has been Mashhad. Using the PICOTS model, the keywords: learning styles, clubs, medical students were used to search the mentioned databases. OR, AND operators and possible combinations of keywords were used when searching for articles in databases. The extracted articles were first evaluated in terms of the research title, then the abstract of the article, and finally the text of the article using the "PRISMA Checklist". In each stage, repetitive articles and articles that did not mention the percentage of learning styles were excluded from the study, and the articles that met the inclusion criteria were stored in the (EndNote software, version 20, Clarivate, USA), and at the end, 53 articles were analyzed.
|
Results: The results of the study showed that the most used learning styles among students of medical sciences in Iran was convergent learning style (32% with 95% confidence interval). In the investigation of the adaptive learning style in the fields of basic sciences during the years 2006 to 2021, the percentage of using this style increased and this trend was statistically significant (P=0.0078).
Conclusion: According to the findings of the study, the most used learning style in medical sciences in Iran is convergent learning style, and considering the characteristics of convergent people, it is necessary to provide effective and efficient training in medical sciences to Students' learning styles should be given special attention so that training can be guided based on their learning styles.
