Abstract
Post-traumatic stress disorder (PTSD) is one of the most widespread and disabling psychiatric disorders among combat veterans. Substantial interindividual variability in susceptibility to PTSD suggests the presence of different risk factors for this disorder. Twin and family studies confirm genetic factors as important risk factors for PTSD. In addition to genetic factors, epigenetic factors, especially DNA methylation, can be considered as a potential mechanism in changing the risk of PTSD. So far, many genetic and epigenetic association studies have been conducted in relation to PTSD. In genetic studies, many single nucleotide polymorphisms have been identified as PTSD risk factors. Meanwhile, the variations in catecholamines-related genes, serotonin transporter and receptors, brain-derived neurotrophic factor, inflammatory factors, and apolipoprotein E are the most prominent candidates. CpG methylation in the upstream regions of many genes is also considered a PTSD risk factor. Accurate identification of genetic and epigenetic changes associated with PTSD can lead to the presentation of suitable biomarkers for susceptible individuals to this disorder. This study aimed to delineate prominent genetic variations and epigenetic changes associated with post-traumatic stress disorder in military veterans who have experienced combat, focusing on genetic and epigenetic association studies.

Abstract
BACKGROUND Calcaneal Lengthening Osteotomy is a surgical technique to correct flexible flat foot deformities in patients who did not show any change in their symptoms after conservative treatment. In this study, the effects of CLO on the kinematic and kinetic changes of gait was analyzed and the clinical and quality of life improvements in children treated by CLO for moderate to severe symptomatic flexible flat foot deformities were assessed. METHODS Participants were seven adolescents (13 feet) with symptomatic FFF who underwent during 2019-2022 and seven (10 feet) healthy children as control group. Three items were evaluated in each foot before and after surgery including: 1. Clinical examination 2.quality of life (using Pediatric Quality of Life Inventory version 4 questionnaire) 3. Gait analysis (Vicon motion systems, Oxford metrics Inc., UK). Also, the kinetic and kinematic analysis between patients and healthy groups were compared. RESULTS Kinematic results of control was significantly better than FFF group. Ankle range of motion(32.94 ± 13.39 compared to 32.94 ± 13.39,P-Value:0.01),foot progression angle (-9.26 ± 7.67 compared to -16.07 ± 9.00,P-Value:0.01),and internal rotation of ankle was higher in control group compared to FFF. FFF patients demonstrated improvement in kinematic results after CLO surgery. Foot progression angle was improved after surgery (-11.31 ± 6.07 compared to -16.19 ± 7.06, P-value:0.00), maximum plantar flexion decreased after CLO surgery due to achil tendon procedure during CLO surgery. Kinetic results of FFF patients showed significant increase in ankle Power in coronal and transverse plane, Also knee and hip power showed similar results.Quality of life parameters showed significant improve in all parameters (Physical,Social, emotional and school function), Also ADKE and ADKF improved after surgery. CONCLUSION CLO surgery significantly improved patients' quality of life of patients with symptomatic FFF. Also, kinetic results showed improvement in some parameters of gait results after CLO surgery. Thus, our study suggested CLO surgery as an excellent surgical option for symptomatic FFF.

Abstract
BACKGROUND Defining standards is the first step toward quality assurance and improvement of educational programs. This study aimed at developing and validating a set of national standards for the Undergraduate Medical Education (UME) program through an accreditation system in Iran using the World Federation for Medical Education (WFME) framework. METHODS The first draft of standards was prepared through consultative workshops with the participation of different UME program stakeholders. Subsequently, standards were sent to medical schools and UME directors were asked to complete a web-based survey. The content validity index at the item level (I-CVI) was computed using criteria including clarity, relevance, optimization and evaluability for each standard. Afterward, a full-day consultative workshop was held and a wide range of UME stakeholders across the country (n = 150) discussed the survey results and made corrections to standards. RESULTS Analysis of survey results showed that relevance criteria had the best CVI as only 15 (13%) standards demonstrated CVI < 0.78. More than two-thirds (71%) and a half (55%) of standards showed CVI < 0.78 for optimization and evaluability criteria. The final set of UME national standards was structured in 9 areas, 24 sub-areas, 82 basic and 40 quality development standards, and 84 annotations. CONCLUSIONS We developed and validated national standards as a framework to ensure the quality of UME training with input from UME stakeholders. We used WFME standards as a benchmark while addressing local requirements. The standards and participatory approach to developing standards may guide relevant institutions.

Abstract
Background Occupational burnout is a mental health problem that among nurses may lead not only to physical and psychological complications, but also to a decrease in the quality of patient care. Considering the stressful nature of surgery, operating room nurses may be at a greater risk. Therefore, the present study aimed to identifying factors associated with the occupational burnout from the perspective of operating room nurses. Materials and methods This qualitative study was conducted in Iran in 2021 using conventional content analysis. Sampling was performed using purposeful sampling method with maximum variation. In order to collect data, individual, semi-structured interviews were performed with 18 operating room nurses. Interviews continued until data saturation. Data were recorded, transcribed and analyzed using steps proposed by Graneheim and Lundman. Data management was performed using MAXQDA-2020 software. Four criteria provided by Guba and Lincoln were used to improve the study’s trustworthiness and rigor. Results A main theme, 4 categories and 15 subcategories were extracted from the data. The main theme is “gradual burnout due to job tension” and categories and subcategories include organizational factors (manager incompetence, organizational indifference, ambiguity in organizational role, organizational inconsistency), interpersonal factors (surgeon aggression, surgeon authoritarianism, surgeon failure to manage stress, unprofessional behavior of nurses), Occupational nature factors (psychological factors and occupational hazards) as well as individual factors (occupational attitude, unprofessional behavior, emotional involvement, demographic factors, physical factors). Conclusion Numerous factors associated with burnout in operating room nurses, which may put the personnel under more pressure. According to these factors, nursing managers and operating room nurses can consider effective strategies to prevent or coping with burnout.

Abstract
Although the chemotherapeutic drug, doxorubicin, is commonly used to treat various malignant tumors, its clinical use is restricted because of its toxicity especially cardiotoxicity. The use of curcumin may alleviate some of the doxorubicin-induced cardiotoxic effects. Especially, using the nano-formulation of curcumin can overcome the poor bioavailability of curcumin and enhance its physicochemical properties regarding its efficacy. In this study, we systematically reviewed the potential cardioprotective effects of nano-curcumin against the doxorubicin-induced cardiotoxicity. A systematic search was accomplished based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for the identification of all relevant articles on "the role of nano-curcumin on doxorubicin-induced cardiotoxicity" in the electronic databases of Scopus, PubMed, and Web of Science up to July 2021. One hundred and sixty-nine articles were screened following a predefined set of inclusion and exclusion criteria. Ten eligible scientific papers were finally included in the present systematic review. The administration of doxorubicin reduced the body and heart weights of mice/rats compared to the control groups. In contrast, the combined treatment of doxorubicin and nano-curcumin increased the body and heart weights of animals compared with the doxorubicin-treated groups alone. Furthermore, doxorubicin could significantly induce the biochemical and histological changes in the cardiac tissue; however, coadministration of nano-curcumin formulation demonstrated a pattern opposite to the doxorubicin-induced changes. The coadministration of nano-curcumin alleviates the doxorubicin-induced cardiotoxicity through various mechanisms including antioxidant, anti-inflammatory, and antiapoptotic effects. Also, the cardioprotective effect of nano-curcumin formulation against doxorubicin-induced cardiotoxicity was higher than free curcumin.

Abstract
BACKGROUND Nano-selenium oxide (NSeO) particles are highly noticeable due to their tissue-protective and antioxidant properties. For this purpose, the effect of NSeO was evaluated on skin flap survival and flap oxidative stress markers in rats. Also, another effect of NSeO was investigated on the expression of mTOR and p-mTOR. MATERIALS AND METHODS Fifty rats were divided into five groups of ten. Skin flap size was 3×8 cm in all groups. Groups were: (1) Sham, (2) Flap Surgery group, (3) Flap Surgery + NSeO, (4) Flap Surgery + Rapamycin (mTOR inhibitor), (5) Flap Surgery + Rapamycin + NSeO. The flap necrosis rate was computed using the paper pattern method on day seven after surgery. After day seven, flap tissues were collected for histological evaluations. Then, malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were measured. Furthermore, the expression levels of mTOR and p-mTOR were measured using the Western blot method. RESULTS Treatment with NSeO significantly reduced necrosis (P<0.05). It also resulted in a decrease in MDA level (P<0.05). Histologically, NSeO reduced inflammation and increased positive signs of tissue healing (epithelialization, neovascularization, fibroblast migration, and granulation tissue). NSeO increased SOD activity significantly (P<0.05), whereas, using rapamycin reversed these effects. Also, in all groups, mTOR changes were not significant. Additionally, p-mTOR expression was significantly reduced in groups that rapamycin was injected. CONCLUSION NSeO can reduce flap necrosis and enhance tissue healing in rats. So, it can potentially be used clinically to promote tissue repair significantly, and its effects are independent of the mTOR pathway.

Abstract
INTRODUCTION Recent investigations have indicated the potential therapeutic role of cannabinoid type 2 (CB2) receptors in various inflammatory-related disorders. However, the role of these receptors has not been studied in skin flap models to date. In this study, we aimed to evaluate the possible involvement of CB2 receptors in the anti-inflammatory effects of sumatriptan, improving the random-pattern skin flap survival in rats. METHODS In a controlled experimental study, 36 male Wistar rats were randomly divided into 6 study groups (n = 6 per group). Two doses of sumatriptan (0.1 and 0.3 mg/kg) were administered intraperitoneally 30 min before harvesting the flap tissue. In a separate group, SR144528 (a selective CB2 receptor inverse agonist) was injected before the most effective dose of sumatriptan to determine the possible involvement of CB2 receptors in its action. Histopathological examinations, the expression level of CB2 receptors (Western blot analysis), and IL-1β and TNF-α concentrations (ELISA) were explored in the skin flap sampled tissues. RESULTS Sumatriptan 0.3 mg/kg remarkably enhanced the skin flap survival in all macroscopic and microscopic investigations compared to the control group (p < 0.001). IL-1β and TNF-α levels were significantly attenuated (p < 0.001), and the expression of CB2 receptors in skin cells was amplified in rats treated with sumatriptan 0.3 mg/kg (p < 0.05) compared to the control group. However, the administration of SR144528 (2 mg/kg) nullified all the protective effects of sumatriptan 0.3 mg/kg. CONCLUSION We discovered that CB2 receptors play a crucial role in the favorable effects of sumatriptan on skin flap survival as a novel mechanism of action. So, targeting these receptors seems to be a dependable method in skin flap surgeries to ensure its survival and prevent tissue necrosis. Further experimental and clinical investigations are needed to ensure the safe clinical application of this method.

Abstract
BACKGROUND Sniffer dogs are able to detect certain chemical particles and are suggest to be capable of helping diagnose some medical conditions and complications, such as colorectal cancer, melanoma, bladder cancer, and even critical states such as hypoglycemia in diabetic patients. With the global spread of COVID-19 throughout the world and the need to have a real-time screening of the population, especially in crowded places, this study aimed to investigate the applicability of sniffer dogs to carry out such a task. METHODS Firstly, three male and female dogs from German shepherd (Saray), German black (Kuzhi) and Labrador (Marco) breeds had been intensively trained throughout the classical conditioning method for 7 weeks. They were introduced to human specimens obtained from the throat and pharyngeal secretions of participants who were already reported positive or negative for SARS-COV-2 infection be RT-PCR. Each dog underwent the conditioning process for almost 1000 times. In the meantime another similar condition process was conducted on clothes and masks of COVID-19 patient using another three male and female dogs from Labrador (Lexi), Border gypsy (Sami), and Golden retriever (Zhico) breeds. In verification test for the first three dogs, 80 pharyngeal secretion samples consisting of 26 positive and 54 negative samples from different medical centers who underwent RT-PCR test were in a single-blind method. In the second verification test for the other three dogs, masks and clothes of 50 RT-PCR positive and 70 RT-PCR negative cases from different medical center were used. RESULTS In verification test using pharyngeal secretion, the sniffer dogs' detection capability was associated with a 65% of sensitivity and 89% of specificity and they amanged to identify 17 out of the 26 positive and 48 out of the 54 true negative samples. In the next verification test using patients' face masks and clothes, 43 out of the 50 positive samples were correctly identified by the dogs. Moreover, out of the 70 negative samples, 65 samples were correctly found to be negative. The sensitivity of this test was as high as 86% and its specificity was 92.9%. In addition, the positive and negative predictive values were 89.6 and 90.3%, respectively. CONCLUSION Dogs are capable of being trained to identify COVID-19 cases by sniffing their odour, so they can be used as a reliable tool in limited screening.

Abstract
BACKGROUND The newly emerged coronavirus disease 2019 (COVID-19) seems to involve different organs, including the cardiovascular system. We systematically reviewed COVID-19 cardiac complications and calculated their pooled incidences. Secondarily, we compared the cardiac troponin I (cTnI) level between the surviving and expired patients. METHODS A systematic search was conducted for manuscripts published from December 1, 2019 to April 16, 2020. Cardiovascular complications, along with the levels of cTnI, creatine kinase (CK), and creatine kinase MB (CK-MB) in hospitalized PCR-confirmed COVID-19 patients were extracted. The pooled incidences of the extracted data were calculated, and the unadjusted cTnI level was compared between the surviving and expired patients. RESULTS Out of 1094 obtained records, 22 studies on a total of 4,157 patients were included. The pooled incidence rate of arrhythmia was 10.11%. Furthermore, myocardial injury had a pooled incidence of 17.85%, and finally, the pooled incidence for heart failure was 22.34%. The pooled incidence rates of cTnI, CK-MB, and CK elevations were also reported at 15.16%, 10.92%, and 12.99%, respectively. Moreover, the pooled level of unadjusted cTnI was significantly higher in expired cases compared with the surviving (mean difference = 31.818, 95% CI = 17.923-45.713, P value <0.001). CONCLUSION COVID-19 can affect different parts of the heart; however, the myocardium is more involved.

Abstract
Introduction: With the continuing growth of aged populations, it is imperative to find ways to maintain and improve the quality of life in old age. It has been documented that grandparents-grandchildren relationship is significantly contributed to quality of life of older adults. This study was conducted to identify the status and associated factors of grandparents-grandchildren relationship in a sample of Iran. Methods: This cross-sectional study was conducted on 377 community dwelling older adults 60 years and over living in Kashan, Iran. A multistage proportional random sampling technique was applied to obtain the sample. The grandparent -grandchildren relationship was measured by a researcher-developed 16-item scale. The data were analyzed using SPSS version 23 and AMOS 23. Results: The mean age of the respondents was 70.42(SD = 8.20) years. About 62% of the respondents were female and 60.7% were married. The average score of grandparents-grandchild relationship was 67.60(SD = 12.47). The multiple linear regression analysis revealed a significant model (F (11, 365) = 19.05, P < 0.001), where information communication technology of grandparents, geographical distance between grandparents and grandchildren, and the quality of relationship between grandparents and parents of grandchildren were the most important predictors of the grandparents-grandchildren relationship. Conclusion: The findings from the current study showed that status of grandparents-grandchildren relationship is moderate to high and influenced by some factors. It is, therefore, suggested that policymakers pay more attention to strengthening grandparent-grandchild relationship by providing educational programs for families and encouraging the elderly to learn and use information communication technology.
