Background and Aim Fibromyalgia syndrome is a chronic disease that causes widespread musculoskeletal pain. It primarily affects women and negatively impacts many aspects of a person’s psychological and social life. This study aimed to compare the effectiveness of cognitive therapy based on mindfulness and compassion therapy on automatic negative thoughts, psychological symptoms, pain intensity, and quality of life in patients with fibromyalgia syndrome. Methods & Materials This research is a quasi-experimental study with a pre-test-post-test design with two experimental and one control group. The statistical study population consisted of all individuals with fibromyalgia syndrome referred to Mehregan Pain Clinic in Mirdamad (District 3), Seyed Khandan Clinic (District 4), and Taleghani Hospital Pain Clinic (District 1) in Tehran City, Iran. Of them, 30 patients were randomly selected and divided into three groups of experimental 1, experimental 2, and control; each group will include 10 people. The instruments used in this study included the World Health Organization quality of life questionnaire (WHOQOL BREF), pain intensity questionnaire (PIS), psychological symptoms questionnaire (Anxiety, Stress and Depression [DASS]), and automatic negative thoughts (QNS). Ethical Considerations This study was approved by the Research Ethics Committee of Arak Branch, Islamic Azad University (Code: IR.IAU.ARAK.REC.1400.005). Results The analysis of covariance showed the effectiveness of both cognitive therapies based on mindfulness and compassion therapy on four variables of pain intensity, psychological symptoms, automatic negative thoughts, and quality of life (P<0.05). Comparing the two intervention methods showed that both therapies had almost the same effect on pain intensity, psychological symptoms, and automatic negative thoughts (P<0.05) but the effectiveness of mindfulness intervention on the quality of life was significantly higher than compassion intervention (P<0.05). Conclusion The results indicate that cognitive therapy based on mindfulness and compassion therapy are suitable for people with fibromyalgia under appropriate treatment. [ABSTRACT FROM AUTHOR]

Using an intelligent method to automatically detect epileptic seizures in medical applications is one of the most important challenges in recent years to reduce the workload of doctors in the analysis of epilepsy data through visual inspection. One of the problems of automatic detection of various epileptic seizures is the extraction of desirable characteristics, in such a way that these characteristics can make the most distinction between different phases of epilepsy. The process of finding the right features is usually a matter of time. This research presents a new approach for the automatic identification of epileptic episodes. In this paper, a deep convolutional network with eight convolutional layers and two fully-connected layers is provided to learn the characteristics hierarchically and automatically identify epileptic episodes using the EEG signal. The results show that the use of deep learning in applications such as learning characteristics hierarchically and identification of different stages of epilepsy has a higher success rate than other previous methods. The proposed model presented in this paper provides an average of 100% accuracy, sensitivity and specificity for the classification of three different epileptic seizures. [ABSTRACT FROM AUTHOR]

Background It is necessary to provide safe care for patients with acute and life-threatening conditions by nurses working in the emergency departments (EDs). These nurses need higher levels of independent performance. Therefore, the competency to provide safe care and having professional nursing autonomy in novice nurses working in the EDs are very important. Objective The purpose of this study was to determine the relationship between professional nursing autonomy and safe nursing care in newly graduated nurses working in the EDs. Methods In this analytical cross-sectional study, the study population consists of all newly graduated nurses working in EDs of hospitals in Guilan, Iran. They all were included in the study using a census sampling method. The tools for collecting information were a demographic form, the assessment of safe nursing care questionnaire, and the professional nursing autonomy scale. Descriptive and inferential statistics (independent t-test, Spearman or Pearson correlation test, and linear regression analysis) were used to analyze the collected data. Results There was a significant relationship between professional nursing autonomy and safe nursing care; for every one unit increase in professional autonomy, the chance of providing safe nursing care increases by 0.133 (P=0.009). Conclusion The significant relationship of professional nursing autonomy with safe nursing care among the EDS nurses shows that if nurses have a greater control over their performance, decision-making ability, and autonomy to act based on patient safety, they can provide better quality care to patients. Therefore, empowering nurses by providing conditions to perform based on professional autonomy, can ultimately lead to better results for the patients and cause overall safety in the EDs.

Background and Aims: Hydroxyapatite coating has allocated a special place in dentistry due to its biocompatibility and bioactivity. The purpose of this study was to evaluate the relation between the hydroxyapatite thickness and stress distribution by using finite element method. Materials and Methods: In this paper, the effect of hydroxyapatite coating thickness on dental implants was studied using finite element method in the range between 0 to 200 microns. A 3D model including one section of mandible bone was modeled by a thick layer of cortical surrounding dense cancellous and a Nobel Biocare commercial brand dental implant was simulated and analyzed under static load in the Abaqus software. Results The diagram of maximum von Mises stress versus coating thickness was plotted for the cancellous and cortical bones in the range between 0 to 200 microns. The obtained results showed that the magnitude of maximum von Mises stress of bone decreased as the hydroxyapatite coating thickness increased. Also, the thickness of coating exhibited smoother stress distribution and milder variations of maximum von Mises stress in a range between 60 to 120 microns. Conclusion: In present study, the stress was decreased in the mandible bone where hydroxyapatite coating was used. This stress reduction leads to a faster stabilization and fixation of implant in the mandible bone. Using hydroxyapatite coating as a biocompatible and bioactive material could play an important role in bone formation of implant-bone interface. [ABSTRACT FROM AUTHOR]

Background and Aim Sciatica is one of the most common diseases of the peripheral nervous system and may be caused by pressure on the sciatic nerve. Due to the fact that piriformis muscle located near the sciatic nerve, piriformis muscle spasm may put pressure on the nerve and cause sciatica and consequently piriformis syndrome. The present study aims to investigate the effect of core stability exercises on pain and inflammation of patients with piriformis syndrome. Methods & Materials This is a randomized clinical trial. The study population consists of all patients with piriformis syndrome referred to medical centers in Arak, Iran from. Of these, 20 were purposefully selected and randomly divided into two groups of control (n=10) and exercise (n=10). The exercise group performed core stability exercises for 6 weeks, while the control group continued their normal life during this period. To examine the differences between the study groups, t-test, Chi-Square test, and McNemar’s test were used. The significance level was set at 0.05. Ethical Considerations This study was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1400.157) and was registered by Iranian Registry of Clinical Trials (ID: IRCT20211003052662N1). Informed consent was obtained from all participants. Results The Mean pain score in the control group decreased from 95.2 to 90.7 after the exercise, which was not statistically significant (P=0.562). In the exercise group, the mean pain score decreased from 91.7 to 33.4, and this decrease was statistically significant (P=0.0); Therefore, at 95% confidence interval, we can say that core stability exercises had a significant effect on the pain of patients with piriformis syndrome (P<0.05). The number of patients with inflamed nerve in the control group decreased from 10 in the pre-test phase to 8 in the post-test phase, but this decrease was not statistically significant (P=0.5). In the exercise group, it was reduced from 10 to 2, and this decrease was statistically significant (P=0.008); Therefore, we can say that core stability exercises had a significant effect on the inflammation of patients with piriformis syndrome (P<0.05). Conclusion Core stability exercises can reduce pain and inflammation in patients with piriformis syndrome. These exercises can be used in the treatment of these patients. [ABSTRACT FROM AUTHOR]

Introduction: Oxidative stress plays a key role in the onset and development of diabetes-related complications. Due to the antioxidant effect of exercise and Urtica dioica (UD), this study aimed to evaluate the effect of one period of endurance exercise and hydroalcoholic extract of Urtica dioica on oxidative stress indices of heart tissue in STZ-Induced diabetic rats. Material & Methods: In this study, 50 Wistar rats (mean±SD weight: 232.12±7.42 g) were randomly divided into five groups: Healthy-sedentary, Diabetes-sedentary, Diabetes-Exercise, Diabetes-Urtica dioica, and Diabetes-Exercise-Urtica dioica. Diabetes was induced by intraperitoneal injection of streptozotocin (45 mg/kg) and 48 hours after injection, blood glucose levels above 300 mg/dl were the criteria for the confirmation of diabetes. Endurance exercise with moderate intensity (5 days/week) and daily gavage of hydroalcoholic extract of UD was performed at 50 mg/kg for six weeks. Data were analyzed in SPSS software (version 20) through Shapiro-Wilk, two-way ANOVA, and Tukey post hoc test. Findings: Two weeks after STZ injection, body weight in the Diabetes-Urtica dioica (P=0.001), Diabetes-Exercise (P=0.034), and Diabetes-Exercise-Urtica dioica (P=0.025) groups decreased, compared to the Healthy-sedentary group, and this reduction continued until the end of the sixth week. In addition, six weeks of endurance exercise and UD extract significantly reduced blood glucose concentration in the Diabetes-Exercise (P=0.001), Diabetes-Urtica dioica (P=0.001), and Diabetes-Exercise-Urtica dioica (P=0.001) groups, compared to the Diabetes-sedentary group. Furthermore, endurance training and UD extract caused a significant increase in catalase (P=0.019) and glutathione peroxidase (P=0.028) values and a significant decrease in heart tissue malondialdehyde (P=0.001). Discussion & Conclusion: Six weeks of endurance training combined with UD extract can increase the antioxidant index and decrease lipid peroxidation in the heart tissue of diabetic rats with streptozotocin.

This research with a pathological investigation and by paying attention to the views of users, seeks to identify the gap of expectations in financial reporting to know the areas of failure in providing useful information for users to make decisions. The research was conducted with a qualitative approach and the method of semi-structured interviews and examining qualitative data through the Data Analysis Spiral. That's why, a total of 21 specialized interviews were conducted with the main users of information. The results showed that the content of financial reporting did not provide all the information necessary for economic decisions and it is not enough to evaluate the management stewardship duties. Financial information due to features such as incompleteness, being retrospective and outdated, complexity, change of format and content, inaccurate judgments and estimates, and opaque relations of its components has little usefulness. The suggested solution to reduce the expectations gap and improve usefulness is the compilation of principles as a general guide for the disclosure of information in financial statements which can be in the form of a revision in accounting standard number one in its structure and content section or explanatory notes or be considered as a non-binding practice guide.

Introduction: Many factors affect memory and learning. One of the most important ones is magnesium, which is essential for the proper functioning of our memory. Magnesium is the fourth most important cation and the second most important intracellular cation after potassium in the body. Magnesium plays an important role in neurotransmission. This study aimed to examine magnesium oxide nanoparticles' effect on the parameters of oxidative stress to treat memory deficit in the rat model of Alzheimer's disease with the help of Amyloid-β. Material & Methods: In this experimental study, 54 adult male rats were divided randomly into nine groups, such as 1. Healthy control group, 2. Alzheimer's control group (rats that underwent stereotactic surgery and received 2nmol/µl of Amyloid-β by intracerebroventricular injection [ICVI]), 3. Sham group (rats that underwent stereotactic surgery and received saline as an Amyloid-β’s solvent), 4, 5, and 6. The healthy experimental groups (healthy rats receiving 2.5, 5, and 10 mg/kg body-weight doses of magnesium oxide nanoparticles by intraperitoneal injection), 7, 8, and 9. Alzheimer's experimental group (Alzheimer's rats receiving 2.5, 5, and 10 mg/kg bodyweight doses of magnesium oxide nanoparticles by intraperitoneal injection). The duration of oral treatment of nanoparticles was 30 days. At the end of the treatment period (30 days), oxidative stress parameters, including superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT), and malondialdehyde (MDA) were measured in neural (brain tissue), and all data were analyzed by one-Factor ANOVA and Tukey post hoc test in SPSS software (version 21) considering a significance level of P<0.05. (Ethic code: IR.IAU.SRB.REC.1398.126) Findings: The results showed that magnesium oxide nanoparticles at 2.5, 5, and 10 mg/kg body-weight doses caused a significant reduction in malondialdehyde levels in Alzheimer's rats. Moreover, the number of antioxidant enzymes including GPX, SOD, and CAT in rats that received 2.5, 5, and 10 mg/kg body-weight doses of magnesium oxide nanoparticles increased significantly. Discussion & Conclusion: The effect of oxidative stress on the progression of Alzheimer's disease and the antioxidant and inhibitor role of magnesium nano oxide in reducing the progression of this disease and on the neurophysiological brain functioning were confirmed. Furthermore, pathways involved in memory mechanisms are improved by mechanisms associated with Amyloid-β disorders. [ABSTRACT FROM AUTHOR]

Introduction: Oxidative stress-induced cell death is activated by free radicals. Exercise and nutrition appear to have the potential to modulate cell proliferation and death. This study aimed to evaluate the combined effect of aerobic exercise and crocin consumption on the prevention of myocardial tissue cell death in male Wistar rats. Material & Methods: In this experimental study, 36 male Wistar rats with a mean weight of 180-200g were randomly divided into six groups (oxygenated water, oxygenated water+crocin, oxygenated water+ exercise, oxygenated water+crocin+exercise, sham, and control). After two weeks of familiarity with the environment and learning the exercises, the training groups were given aerobic exercises for six weeks. All groups, except for the sham and control, were given 1 mM H2O2 and subcutaneously injected with 12.5 mg crocin. 48 hours after the last training session, the rats were anesthetized with CO2 after 10-12 hours of fasting, and their myocardial tissue was isolated. To measure the proapoptotic genes, Real-Time PCR was used; moreover, one-way analysis of variance and Scheffe post-Hoc test were employed for data analysis. A P-value of ≥0.05 was considered statistically significant. (Ethic code: IR.SSRI.REC.1397.254) Findings: The findings showed that six weeks of aerobic training in water, consumption of crocin supplementation, as well as the combination of aerobic exercise and crocin supplementation, reduced the expression of the genes of the internal apoptotic pathway at a significant level of ≥ 0.05. Discussion & Conclusion: According to the results of the present study, it seems that the interaction and combination of aerobic exercise in water and crocin antioxidant supplement should be used to reduce the apoptosis of the myocardial tissue, less cell damage, and ultimately the health of the myocardial tissue.

To this end, a researcher-made questionnaire was designed and randomly distributed among 523 Persian speakers in 4 different age groups (15-25, 26-35, 36-45, and 45 years and older). As far as it is concerned to the methodology, it is questionnaire-based survey benefiting from the qualitative components and quantitative analysis. The theoretical framework was based on Hyland’s (1996) and Varttala’s (2001) classifications of hedges. The statistical tests including T-test, ANOVA, and Tukey were used for data analysis. The findings showed that women used “evidential verbs” more than men to show their uncertainty, while the opposite was true for “judgmental verbs”. Furthermore, the statistical analysis revealed that there was a significant difference in the use of “judgmental, modal, and evidential verbs” among participants in different age groups. Finally, the results indicated that Persian speakers used only five groups of Hyland’s and Varttala’s hedging classifications in their everyday speech. [ABSTRACT FROM AUTHOR]

Based on the co-occurrence analysis method, the scientific fields can be extracted and the relationships between them can be detected directly from their subject content. With this view in mind, the aim of this study is to determine the subfields of informetrics and the relationships between these subfields, and thus to investigate the efficiency of this method and its application in mapping of the structure of scientific fields. This is an applied study using scientometrics, coword analysis and network analysis methods. In order to determine the main concepts in the field of informetrics, all scientific papers of international scholars in this field were extracted from WOS (included 7375 records from 1991 to 2012). Then after refining and standardizing the keywords of these articles, a selected list of these keywords was prepared. Using the results of the data analysis, the trend in publication growth in the field of informetrics and each of its subfields was identified. Then the thematic maps were drawn using Vosviewer and Nodexl software. The resulting data of the maps and the structure of the formed clusters and their inter-relationships have been analysed. Based on the resulted maps the concepts such as information science, library, bibliometric analysis, innovation and text mining are the most widely used topics in the field of informetrics. The co-word occurrence maps drawn at different time periods show the changes and stabilities in the concepts and terms related to the field of informetrics. Some words like "bibliometric analysis" are present in all the studied years, while others disappear over time. In interacting with developments and new technologies, the new concepts can be created.

Background: Considering the emergence of electronic health records and their related technologies, an increasing attention is paid to data driven approaches like machine learning, data mining, and process mining. The aim of this paper was to identify and classify these approaches to enhance the quality of clinical processes. Methods: In order to determine the knowledge related to the research question, a systematic literature review was conducted. To this end, the related studies were searched in the web of science documentation database, as a comprehensive and authoritative database covering 1536 scientific publications from 2000 to 2019. The studies found from the initial search were investigated and the relevance of their title with the inclusion and exclusion criteria was determined. As a result, 184 articles were selected. Further investigations resulted in 84 studies that remained after reviewing the abstracts and full texts of these articles. These studies were also evaluated with regard to their field of study and the quality of presented evidence. Consequently, the final synthesis was performed on the evidence extracted from these articles. Results: Examination of the identified evidences resulted in 4 general categories of "event-based approaches", "process intelligence", "clinical knowledge systems", and "data-driven control and monitoring" as data-driven approaches that can be used to manage the quality of clinical processes. Conclusion: The findings demonstrated that event-bases approaches had more applications as data driven approaches in the context of health care. Furthermore, process mining is a novel approach that can be used by future studies. The results of this study can be used to complement clinical governance procedures regarding emerging data driven opportunities.

Introduction: One of the most common childhood disorders considered by psychologists and psychiatrists is Attention Deficit/Hyperactivity Disorder, which leads to attention deficit, hyperactivity and impulsivity in affected people.

Background and Aim Several microRNAs are involved in regulating muscle mass, which plays an essential role in hypertrophy and atrophy of skeletal muscle, The present study examined the expression of some genes as regulators of muscular atrophy following a period of inertia in rats. Methods & Materials For this purpose, 18 male Sprague-Dawley rats were divided into three groups (Control, Exercise+inactivity, and Inactivity). The exercise+inactivity group run on the treadmill for 18 weeks and five times per week. The hindlimb of the animal was immobilized for seven days with the casting method. Soleus muscle was extracted and the expression of the genes was measured by the RT-PCR method. Univariate ANOVA and Tukey post hoc test was used to determine the differences (α=0.05). Ethical Considerations The Ethics Committee of the Tehran University of Medical Sciences Research approved this study (Code: IR.SUMS.REC.1396.S 463). Results Results showed that immobilization in both Exercise+ inactivity and inactivity groups, compare to the control group, increased expression of miR-1 genes (P<0.10), FOXO3a (P<0.001) and decreased expression of miR-206 (P<0.007) and IGF-1 (P<0.001). This difference was statistically significant. Conclusion According to the results of this study, it can be said that changes in the expression of RNAs by chromatography cause changes in the expression of muscle regulating genes, and although endurance exercises have protective effects, they cannot prevent these changes.

Background and Aim Alzheimer's Disease (AD) is a neurodegenerative brain disease that gradually destroys memory and cognitive skills. The disease is caused by the formation of beta-amyloid plaques, oxidative stress, dysfunctions in the cholinergic system, neuronal killing inflammation, and ultimately brain atrophy. Donepezil and hyoscyamoside have inhibitory effects on these pathogens; therefore, their impact on the learning process of Alzheimer’s rats in the Morris Water Maze was investigated. Methods & Materials In the present experimental study, 60 male rats of Wistar breed with approximately 7 weeks age within the control group (rats that received normal water and food), the PBS group (underwent surgery), PBS group (received solvent Aβ), the first Alzheimer›s group (animals that received betaamyloid by Alzheimer’s surgery, second Alzheimer’s group (after Alzheimer’s surgery, they received 1 cc of normal saline daily, and treatment groups that treated the rats with beta-amyloid after Alzheimer. In the hyoscyamoside group, they received 10 mg/kg daily of hyoscyamoside for 28 days. The donepezil group received it 4 mg/kg daily for 28 days by gavage. The Morris Water Maze test was used to evaluate learning and memory. Data were analyzed by ANOVA statistical analysis and Post Hoc test. Ethical Considerations The Ethics Committee in Biomedical Research, Islamic Azad University, Science and Research Branch approved the research (Code: IR.IAU.SRB.REC 1397.057) Results Beta-amyloid injection caused extensive damage to memory. The treatment groups with hyoscyamoside and donepezil spent less time and distance with a significant level (P<0.001) than the group of Alzheimer’s patients to find the hidden platform. In the reminder phase, where the previously hidden platform was located, they spent more time, with a significant level (P<0.001) in the local quarter. Conclusion Treatment of rats with hyoscyamoside and donepezil improved spatial memory in Alzheimer’s rats. They appear to play a significant role in the prevention and treatment of Alzheimer’s disease. [ABSTRACT FROM AUTHOR]

Background and Aim The present study aimed to investigate the effect of a 10-week resistance training on the serum levels of insulin resistance index (HOMA-IR), the serum levels of liver enzymes, chemerin, and resistin in healthy and type 2 diabetic rats. Methods & Materials In this experimental study, 40 Wistar rats with the mean±SD weight of 200±48 gr were randomly divided into 4 groups (normal control, diabetic control, diabetic resistance training, and resistance training). The training groups performed regular resistance exercises for 10 weeks by ladders. Twenty-four hours after the last training session, the blood sample of rats was collected for resistin, chemerin, insulin, and liver enzymes. The obtained data were analyzed using one-way Analysis of Variance (ANOVA), Tukey posthoc test, Analysis of Covariance (ANCOVA), and Bonferroni posthoc test at a significance level of 0.05. Ethical Considerations This study was approved by the Research Ethics Committee of Arak University of Medical Sciences, Iran (Code: IR.ARAKMU.REC.1394.329). Results Diabetes induction significantly HOMA-IR, the serum levels of liver enzymes, resistin, and chemerin in the diabetic control group, compared to the healthy control group (P< 0.05). Resistance training also significantly decreased insulin HOMA-IR, the serum levels of liver enzymes, resistin, and chemerin in the diabetic resistance training group, compared to the diabetic control group (P<0.05). Conclusion The obtained data suggested that resistance training improved liver enzymes in type 2 diabetic rats by decreasing the insulin HOMA-IR, the serum levels of chamirin, and resistin.

Background and Aims: Periodontitis is one of the most common oral diseases with the various incidence rates in different populations. A number of bacteria are considered as the major etiologic agents of periodontitis. The aim of the present study was to determine the prevalence of periodontopathogen bacteria in patients using both PCR and culture techniques. Materials and Methods: In this study, one-hundred patients (including 62 females and 38 males with an average age of 49±11.5 years) with adult periodontitis referred to periodontics department of School of Dentistry/Tehran University of Medical Sciences were investigated. The samples were taken and sent immediately to the laboratory for culture and molecular evaluation. The PCR was performed using specific primers and the statistical analysis of data was performed using SPSS statistic software andMcNemar test. Results: The results demonstrated that the total detection rate in culture method was 64%. The rate of Aggregatibacter actinomycetemcomitans (Aa) was 28% which was significantly higher than that of Porphyromonas gingivalis (Pg) (6%) and Prevotella intermedia (Pi) (3%). 27% of cases showed mixed bacterial growth. 65% of patients were positive using molecular method. The rate of Aa (30%) was significantly higher than that of Pg (7%) and Pi (5%). The mixed PCR positive rate containing of Aa, Pg and Pi was (23%). Conclusion: In this study, it was found that most of the bacteria isolated using culture and molecular methods were Aa, Pg and Pi, respectively. Although the detection frequencies of both techniques were similar, the specificity, sensitivity and bacterial detection speed of the PCR technique is obviously higher. Therefore, the use of molecular techniques is strongly recommended. However, both techniques seem to be suitable for microbiological diagnostics [ABSTRACT FROM AUTHOR]

Background: Breast cancer is the most common cancer in women. It jeopardizes different aspects of individual health including mental health. The aim of the study was to evaluate mental health among women who had survived breast cancer and also among the general population Methods: In a case-control design, we recruited 60 participants in two groups. The first group had survived breast cancer and had undergone mastectomy while the other group was selected from the general population. Mental health status of participants was measured by general health questionnaire (GHQ-28). For analyzing the data, Student t-test and logistic regression were used. Findings: Data analyses did not reveal any significant differences in mental health scores between the two groups. Although the risk of psychological distress increased 44% in breast cancer patients, there were not any statistically significant differences between the two groups. Conclusion: Iranian women survived from breast cancer are not significantly different with the general population in terms of mental health. [ABSTRACT FROM AUTHOR]
