Abstract
Managing overweight and obesity is associated with lower risks of chronic diseases like diabetes. Digital health, particularly smartphones or m-health, effectively manages body weight. Technologies such as telemedicine services, mobile health (mHealth) or the use of mobile phones or portable digital devices in healthcare services and wearable devices can be used in this field. Therefore, this study was conducted to understand the impact of digital health technologies on weight management in diabetic patients.
Methods: The present study is a systematic review study that was initially searched using a systematic review of published studies in the field of digital health for weight management in diabetic patients from October 1401 to October 1402. Our study was conducted in two rigorous steps. Firstly, we performed a systematic review by searching for publications on Digital Health Solutions for Body Weight Management in Diabetic Patients until 12 October 2022. We meticulously combed through two comprehensive databases, PubMed and Web of Science, using a set of specific and relevant keywords. After a thorough screening and full-text assessment, we handpicked eight documents for this study. We cross-referenced with the companies' websites producing the identified applications to enrich our findings further.
Results: In the initial search, 223 documents were identified and after screening and qualitative evaluation, eight documents were selected for this study. Our research uncovered a range of mHealth apps that have shown promise in weight management for diabetic patients. These apps have demonstrated potential efficacy, high acceptability, and favorable user experiences. Importantly, they have also improved diabetes management and quality of life for the users.
Conclusion: Our review of digital health solutions has not only illuminated their potential in weight management for diabetic patients but also opened up new avenues for a more personalized, engaging, and practical approach to this issue. As technology continues to advance, these interventions hold the potential to revolutionize diabetes self-management, significantly enhance the quality of life, and contribute to better health outcomes for individuals living with diabetes.

Abstract
Background: The increasing prevalence of non-alcoholic fatty liver disease (NAFLD) in recent years has raised concerns about its significant risks for public health. According to previous studies, a diet with low phytochemicals and high inflammatory index is related to non-alcoholic fatty liver disease. In this study, we intend to investigate the relationship between inflammatory diet and phytochemical diet with NAFLD.
Methods: In this case control study, 112 newly diagnosed patients with NAFLD referred to the Shahid Rahimi Hospital clinic in Khorramabad between January 1400 and April 1401 and 112 healthy individuals without NAFLD and any other chronic diseases as the control group, with the range 23-59 years old were selected. General information, demographics, physical activity level and food intake were collected using general information questionnaire, physical activity questionnaire and valid semi-quantitative food frequency questionnaire (FFQ). The energy received between the people of the two groups was adjusted. People's diet was divided into two anti-inflammatory and pro-inflammatory groups based on the DII index based on the score quartiles.
Results: The results showed a significant relationship between DII score and NAFLD in the crude model (OR: 2.22, 95% CI: 1.04 -4.73), model I (adjusted for energy and age classification) (OR: 2.4, 95% CI:1.07-5.58), model II (adjusted for model I+physical activity, sex, education) (OR:2.77, 95% CI:1.14-6.77) and model III (model II+BMI) (OR: 2.16, 95% CI: 0.81-5.71) and DPI score and NAFLD the crude model (OR: 0.69, 95% CI: 0.32-1.47), model I (adjusted for energy and age classification) (OR: 0.56, 95% CI: 1.29-5.58), model II (adjusted for model I+physical activity, sex, education) (OR:0.58, 95% CI: 0.23-1.44) and model III (model II+BMI) (OR: 0.65, 95% CI: 0.24-1.75).
Conclusion: The results obtained from this study showed an inverse relationship between following an anti-inflammatory diet and the risk of NAFLD. However, there was no correlation between receiving a diet with a high phytochemical index and NAFLD.

Abstract
Background: Prolonged stay in intensive care unit (ICU) can worsen the patient's prognosis and represents a significant economic burden. Previous studies have reported the effectiveness of early mobilization in reducing length of stay in ICUs for adult patients; However, conflicting results have been reported regarding its effects on pediatric patients. Therefore, this research aimed to investigate the impact of early mobilization on the length of stay in the pediatric intensive care unit (PICU) in ventilated children.
Methods: This pilot quasi-experimental study was conducted on 60 children admitted to the Children's Medical Center hospital from March 2020 to June 2021. For the control group, routine care (standard physiotherapy) was started on the second day of intubation and continued until discharge from the intensive care unit. In this study, we used an early mobilization protocol including active and passive exercises. The intervention was implemented by Pediatric intensive care unit nurses under supervision of a pediatric critical care fellowship physician. In the intervention group, passive exercises were started on the second day of intubation. At each shift, the nurses check the level of sedation and presence of delirium in the patients using the Richmond Agitation-Sedation Scale and the Cornell Assessment of Pediatric Delirium questionnaire. If the results showed that the sedation was not deep and delirium was not present, then active exercises were initiated. If the child did not achieve an adequate score indicating the absence of deep sedation and delirium, the patient remained in the passive exercise phase. The length of stay was recorded based on the patients' records. Descriptive and inferential statistics were used for data analysis using SPSS version 23.
Results: The results showed that there was no significant difference in the length of stay in the pediatric intensive care unit (PICU) between the control (23.20±6.34 days) and intervention (22.60±6.18 days) groups (P=0.77).
Conclusion: The implementation of early mobilization did not significantly reduce the length of PICU stay for pediatric. The researchers are advised to identify and evaluate evidence-based guidelines for implementing early mobilization in children with different diagnoses.

Abstract
Background: Given the significance of patient care in obstetrics and gynecology, we aimed to assess the satisfaction of Tehran University of Medical Sciences residents with their training program in this field.
Methods: In this cross-sectional descriptive study, 77 obstetrics and gynecology residents from the first to fourth year at Tehran University of Medical Sciences participated with informed consent, adhering to ethical principles, from April to October 2023 across four teaching hospitals: Imam Khomeini, Shariati, Mohib Yas, and Arash.The researcher developed a questionnaire consisting of 62 online questions, including 15 demographic questions and 47 related to satisfaction. Most of the questions are statements with five response options: strongly agree, agree no opinion, disagree, and strongly disagree. Each criterion was assessed and classified on a scale from one to five. The assistants' satisfaction levels were assessed in various areas, yielding an overall score of 47-235. Scores above 70% indicate high satisfaction, 50-69% reflects average satisfaction, and below 50% signifies dissatisfaction. It's important to clarify that the areas include clinics, with specific focus on rotation shifts for assistants in gynecology, oncology, prenatal care, and infertility. Data analysis was conducted using SPSS software, Version 22. Descriptive statistics included the median and range for continuous variables (number of surgeries and satisfaction scores) and frequency and percentage for nominal variables (quality of satisfaction) across three defined levels of desirability: appropriate, relatively appropriate, and unfavorable.
Results: Satisfaction with the number of surgeries and educational quality at Imam Khomeini Hospital was higher than at other hospitals (P=0.07). Significant differences were noted in the gynecology and pelvic surgery departments, with residents at both Imam Khomeini and Arash hospitals reporting greater satisfaction in gynecology (P=0.018) and pelvic surgery (P=0.036). Additionally, regarding the conference program and educational mornings, Shariati Hospital reported a higher level of satisfaction in this area (P=0.47).
Conclusion: The satisfaction scores in various areas indicate that 64.5% of assistants at Imam Khomeini Hospital rated their educational status as appropriate, while 60% at Arash Hospital rated it as relatively good, and 25% at Yas Hospital found it unfavorable.

Abstract
Background: Increasing the prevalence of non-contagious and chronic disorders such as Non-alcoholic fatty liver disease (NAFLD) takes the attention of researchers. NAFLD recognized by abnormal accumulation in the liver tissue. The aim of present study is investigating the association between liver size liver enzymes and degree of fatty liver in patients with NAFLD.
Methods: Based on the inclusion criteria, 100 Patients were selected from those referred to the radiology and ultrasonography clinic in Golestan Hospital, Ahvaz, for fatty liver evaluation. The study was carried out during May 2022 to April 2023. Liver enzymes, including alanine aminotransaminase (ALT) and Aspartate aminotransferase (AST), were measured. Based on the ultrasonography results, patients were divided into four groups: healthy, mild fatty liver, moderate fatty liver, and severe fatty liver. Ultrasonography was carried out by an experienced expert. All demographic information of patients was collected. Data were analyzed by SPSS (V25).
Results: According to ultrasonography results, the mean of span was 148.4 ± 14.7 cm, which was significantly higher in patients with grade II of NAFLD (P<0.001). Further analysis revealed the highest difference between grades I and II (P<0.001). Also, a significant difference between grades II and III and grades III and I were found (P<0.001). Our data showed a significant relationship between body mass index (BMI) and NAFLD grades (P<0.001). The mean of BMI in grade I was significantly lower than in grades II and III (P<0.05). Our findings demonstrated that the mean of ALT in grade I was significantly lower than in grades II and III (P<0.05). In this line, the highest AST level was seen in grade III (P<0.001).
Conclusion: Our study showed that as NAFLD progresses, the enzymes and size of the liver increase. Based on ultrasound findings, the increasing liver size suggests NAFLD grade II, while the rise in AST and BMI suggests NAFLD grade II -III and progression of cirrhosis.

Abstract
Background: Medical errors are one of the biggest problems of the health system in countries. Identifying the factors responsible for these errors is crucial to designing optimal strategies to reduce such occurrences. The aim of this study was to investigate the type and nature of medical errors.
Methods: In this cross-sectional descriptive study, all documented medical errors that occurred between March 2021 and February 2022 at Firoozgar Educational and Medical Center were thoroughly examined. The data collection involved reviewing records from various departments within the center to ensure a comprehensive analysis of error types. The extracted data were processed and analyzed using SPSS v.22 software, allowing for statistical evaluation and identification of potential patterns or trends in medical errors over the specified period.
Results: A total of 214 cases were reviewed. 45.3% of the recorded medical errors occurred in the morning shift, 20.6% in the evening shift and 34.1% in the night shift. The highest number of medical errors was reported by nurses (40.7%), followed by physicians (16.8%) and paramedics (11.7%). The etiology of most medical errors was systemic errors (63.6%) followed by pharmacological errors (15.4%) and technical errors (13.1%) and the most reported systemic errors were of insufficient supervision. Most of the patients who had medical errors were admitted to the inpatient wards (40.7%) and later to the surgical wards (17.3%) and ICU (12.6%). 62.1% of medical errors did not cause any specific complication and in 33.2% of cases, mild complication, 10.7% moderate complication and 3.3% severe complication occurred for patients. 62.1% of medical errors had no consequences for anyone, and in 36.9% of cases, the consequences of errors were to the patient and 1% of the consequences of errors were to the organization and employees.
Conclusion: Most of the reported medical errors were performed by nurses and were uncomplicated errors. Establishing transparent and accurate self-reporting systems is essential to identify medical errors of all employees.

Abstract
Background: The type of delivery significantly affects a woman's life and her newborn's health. Various factors, including medical conditions, personal preferences, and cultural influences, shape this decision. Increasing cesarean delivery rates have raised concerns about associated risks. This study examines the health impacts of different delivery types on mothers and newborns in Yazd hospitals, with a focus on maternal and neonatal outcomes.
Methods: This cross-sectional analytical study involved a substantial cohort of 69,321 mothers who delivered in Yazd between March 21, 2018 to March 20, 2022. Comprehensive data were collected from Iman Hospital and relevant online patient records. To analyze the relationship between delivery type and health outcomes, independent samples t test and chi-square test were utilized. Additionally, odds ratios were calculated to assess relative risks concerning various maternal and neonatal outcomes. SPSS 26 software was employed for all analyses, with a significance level set at 5% to ensure robustness in the findings.
Results: The average age of participants in the study was 34.45±6.44 years, highlighting a mature population of mothers. Neonatal outcomes indicated that babies delivered naturally were more likely to have unfavorable Apgar scores (ranging from four to six) when compared to infants delivered via cesarean section (CI=0.99-1.55, P=0.05, OR=1.24). Furthermore, naturally delivered infants showed a significantly higher likelihood of having Apgar scores below six (CI=0.90-1.03, P=0.001). Alarmingly, the odds of neonatal death were found to be 1.22 times higher for cesarean births (CI=1.19-1.25, P<0.001). Additionally, mothers who underwent cesarean deliveries exhibited nearly a 4.9 times higher likelihood of requiring intensive care after delivery (CI=4.71-5.12, P<0.001, OR=4.9) and were 14.3 times more likely to be hospitalized postoperatively compared to those who had natural deliveries (CI=3.53-1.31, P<0.001, OR=14.33).
Conclusion: This study indicates that cesarean delivery is associated with higher complications for both mothers and newborns, highlighting the need to promote natural childbirth for better health outcomes.

Abstract
Background: A range of diseases can result in end-stage renal disease (ESRD), characterized by a gradual decline in kidney function and associated with significant morbidity and mortality. Currently, renal transplantation as the most effective treatment for managing ESRD. Tissue engineering presents a considerable opportunity to expand the available supply of donor organs for kidney transplants. The aim of this research was to develop a suitable technique for preparing decellularized kidney scaffolds from human tissues.
Methods: The present study was carried out from April 2019 to August 2019 in Mashhad University of Medical Sciences. In this study, two decellularization protocols were compared using sections of human kidney tissue. Therefore, two human kidneys which collected from Ghaem and Imam Reza hospitals were used. In the first protocol, detergents such as 1% Triton X-100 (1A) and 1% SDS (Sodium Dodecyl Sulfate) (1B) were employed, followed by the application of DNase I. The second protocol utilized 0.5% SDS (2A) and 1% SDS (2B). The effectiveness of these techniques was evaluated using hematoxylin and eosin (H&E) staining, 4',6-diamidino-2-phenylindole (DAPI), DNA quantification, and immunohistochemistry (IHC).
Results: Based on H&E staining results, comparison of the decellularized and native human kidney tissues showed a successful elimination of cell nuclei and the ameliorate extracellular matrix preservation in triton-treated scaffolds (1A) in comparison with the SDS-treated scaffolds (1B) at all times protocols. Furthermore, DNA quantification illustrated triton X-100 in removing DNA was more effective in eliminating DNA from kidney tissues compared to other protocols in renal tissues. In addition, IHC staining demonstrated that the expression of collagen IV and laminin was preserved throughout the decellularization process with Triton X-100 on day fifth. Also, IHC staining indicated human leukocyte antigen (HLA) was completely eliminated in the cortex-medulla of human scaffolds treated with Triton X-100 within day fifth.
Conclusion: Our results demonstrated that triton X-100 outperformed SDS as a detergent for decellularizing human kidneys. Meanwhile these results indicate suitable method for decellularization of human kidneys to produce functional kidneys.

Abstract
Background: COVID-19 is one of the most recent known human infections that has resulted in a global pandemic, causing high rates of morbidity and mortality worldwide. This study evaluated the clinical and epidemiological characteristics of the waves of the corona epidemic within a university surveillance system in southern Iran.
Methods: This cross-sectional study analyzed data from 24,132 individuals with Covid-19 in the registered waves from the beginning of the Corona epidemic from March 2020 to March 2021 in one of the southern universities of Iran. Information on age, gender, number of infections, severity, hospitalization, recovery rate, dominant strain, and compliance with protocols separately for each wave from 2020 to 2021 was collected from the University's databases. After calculating the cumulative incidence rate, mean and standard deviation and drawing graphs, chi-square, Mann-Whitney and one-way ANOVA were used in SPSS26 at a significance level of 5%.
Results: The cumulative incidence of the disease was 11.36%, with a relative frequency of hospitalization at 11.7% and an average hospital stay of Seven days. The highest percentage of protocol compliance was applied in the initial waves. The highest frequency of infection was in the third wave, where men were more infected than women in all waves except the 4th and 5th waves. High blood pressure was the most common underlying disease in patients and the most lung involvement was observed in the fifth wave. Most of the patients have recovered, and the highest rate of recovery was observed in the sixth wave. Significant associations were found between hospitalization duration, underlying conditions, and clinical symptoms across different waves (P<0.001). Systemic symptoms were the most common, and there was a notable difference in radiological findings between waves (P<0.001).
Conclusion: The findings of this study emphasize the significant impact of underlying diseases and the severity of clinical symptoms on hospitalization outcomes. They also highlight the need for appropriate evidence-based management strategies and consideration of clinical changes and radiological patterns when evaluating diseases in different groups.

Abstract
Background: Communication and cooperation among health care organizations have become nowadays crucial for improving the quality and equity in providing health services, and integration has been expressed as a solution by the World Health Organization. The purpose of this review was to identify the challenges and solutions of integration in health services.
Methods: This research was carried out from September 2023 to April 2024. All articles on the challenges and solutions of integration in health, using scoping review, were identified and used in the PubMed, Scopus, Web of Science and Google Scholar search engines in the period from 2000 to 2024. The total number of English articles found was 4996, of which 662 were removed due to repetition. Among the remaining 4334 articles, 4249 articles whose titles and abstracts were not related to the research topic were removed, left a total of 85 articles, and after reviewing the full text of the articles, 27 articles entered the data extraction phase, which were finally analyzed using the framework analysis method.
Results: Finally, 27 articles were selected from which, 46 challenges and 26 solutions were extracted as to the integration in health services and categorized based on the framework of WHO six building blocks in five areas of governance and leadership, financing, human resources, information system and service delivery. The most important challenges of integration include; weakness in planning, imbalance of power between organizations, differences in geographical and spatial boundaries of organizations, weakness in maintaining data security, workforce resistance and the lack of laws and regulations, needs assessment from patients, related knowledge, financial resources, suitable payment models, integrated communication and information systems and interoperability between technologies.
Conclusion: Integration of health service endures a series of challenges such mainly as the lack of rules and regulations for collaborative processes and resistance from providers and employees requiring innovative solutions. Addressing issues such as stakeholder power-benefit analysis, interoperability and data sharing among the providers could be essential for successful integration.

Abstract
Background: Preterm premature rupture of membranes (PPROM) significantly impacts perinatal mortality and maternal-fetal outcomes. The purpose of this study is to investigate the frequency of maternal risk factors, maternal and fetal outcomes and the role of care in the occurrence of outcomes.
Methods: This retrospective cross-sectional study involved 317 pregnant women with premature rupture of membranes (PPROM) at Shahid Beheshti Hospital in Isfahan, between April 2020 and April 2022. Data were collected from medical records, including demographic information, risk factors, and maternal and neonatal outcomes. Patients were categorized into two groups: those receiving care (24-34 weeks of gestation) and those undergoing pregnancy termination (less than 24 weeks or more than 34 weeks). The chi-square test was used for qualitative variables, while the T-student test was applied for quantitative variables.
Results: In this study, the average age of patients was 29.42±6.56 years. The most common risk factors for PPROM were 20.2% for abortion records, 20.2% for urinary infections, 18% for cervical insufficiency, and 13.6% for gestational diabetes. Comparing maternal outcomes between the two groups revealed that chorioamnionitis occurred more frequently in the care group (18% vs. 2%, P=0.0001), as did emergency cesarean sections (37% vs. 4.5%, P=0.0001) and NICU hospitalization (71% vs. 17%, P=0.001). In the next stage, a regression test identified the independent effects of variables on maternal and newborn outcomes without intervention or confounding factors. The analysis indicated that mothers in the care group experienced significantly more complications than those in the pregnancy termination group, and their babies also faced significantly more complications.
Conclusion: The study results indicate that a history of abortion, urinary infections, cervical insufficiency, and gestational diabetes are significant risk factors for PPROM. Expectant management of PPROM is associated with more neonatal and maternal complications than pregnancy termination. Thus, timely identification of these risk factors allows healthcare providers to educate mothers and potentially prevent and manage them, significantly reducing the incidence of PPROM and its complications.

Abstract
Background: Spinal cord injury (SCI) is a significant medical and social issue, leading to varying degrees of sensory and motor impairments. Most men experience sexual dysfunction and fertility problems. These issues can be partially attributed to pathophysiological mechanisms, including damage caused by reactive oxygen species (ROS). Targeted antioxidant therapy can significantly reduce oxidative stress and neuro inflammation. This study sought to examine the impact of selenium and astaxanthin on sperm parameters and the recovery of sensory-motor function in rats with spinal cord injury (SCI).
Methods: This experimental study utilized the rat animal model and was carried out at the Neuroscience Research Center Laboratory of Tabriz University of Medical Sciences from December 30, 2022, to November 27, 2023. Fifty adults male Wistar rats were randomly allocated into five groups of ten: control, sham, SCI, selenium-supplemented, and astaxanthin-supplemented. Except for the control and sham groups, spinal cord injury was induced in all other groups. Six weeks after the injury and upon completion of the treatment, the effects of selenium and astaxanthin supplementation on sperm parameters and spinal cord repair were assessed. The Basso, Beattie, and Brenham (BBB) scale was employed to evaluate motor function, while the Von Frey test was utilized to assess sensory status.
Results: A considerable rise in sperm concentration was noted in both the selenium-fed group and the astaxanthin-fed group when compared to the spinal cord injury group (P=0.001). Supplementation with selenium and astaxanthin improved sperm concentration, progressive motility, and viability, bringing these parameters close to control levels (P<0.001). However, neither of these substances had an effect on abnormal sperm morphology (P>0.05). Both selenium and astaxanthin supplementation enhanced the motor and sensory functions of the injured rats (P<0.001), with selenium showing a greater role in promoting repair compared to astaxanthin (P<0.001).
Conclusion: Selenium and astaxanthin supplements improved sperm parameters, except for sperm morphology, and were effective in enhancing motor and sensory functions after spinal cord injury. Selenium was found to be more effective than astaxanthin in promoting spinal cord repair.

Abstract
Background: Considering the emergence of new diseases, increased prevalence of nosocomial infections, and microbial resistance in recent years, it is necessary to disinfect the hands with a suitable hand sanitizer, as instructed by the Center for Disease Control (CDC). This is because hand hygiene is the most important way to control infections. Surgical hand antisepsis protocols emphasize the importance of both mechanical cleaning and antimicrobial action to effectively eliminate microbial contamination. Recommendations from organizations such as the Association of Perioperative Registered Nurses (AORN), the World Health Organization (WHO), and the Association for Professionals in Infection Control and Epidemiology (APIC) underscore this principle. While routine handwashing removes visible debris and transient microbes, surgical hand antisepsis requires additional steps and the use of antimicrobial agents. This may involve a surgical scrub with an antimicrobial soap or the application of an alcohol-based hand rub (ABHR). The latter approach has demonstrated greater efficacy in reducing microbial contamination compared to soap and water alone. Since a few compressive studies in Iran have dealt with global standards for disinfectants, this study investigated the effects of surgical scrub based on the European standards with TGSept AL Plus, produced by the research team of Tajhiz Gostar Sharif , on normal flora of hands in a group of the operating room medical staff in Hazrat Fatemeh Plastic Surgery and Repair Hospital of Tehran, in 2023.
Methods: This study evaluated the short-term durability and effectiveness of this solution according to the EN12791 standard on microorganisms and microbial contamination reduction. To this end, 30 members of the surgical team were randomly selected. The bacterial sampling was performed three times: after washing the hands with common detergents, after hand scrubbing with the studied disinfectant (about 90 seconds), and three hours after surgery. The samples were immediately transferred to a laboratory for swap culture and pour plate test.
Results: Then bacterial colonies were counted, contamination reduction was measured, and the shelf life of the solution was determined according to the standards. Results showed that a 60-to-90-second scrub with an alcohol-based disinfectant is the best way to reduce hand contamination and, thereby, nosocomial infections.
Conclusion: Based on the study findings, alcohol-based solutions can be recommended for surgical scrubs, according to WHO guidelines.

Abstract
Background: Choosing a specialty in medicine is an important decision for the individual. It is also important decision for the health system. This study aimed to investigate the factors affecting the interest of specialized assistants to continue studying in subspecialized fields.
Methods: This descriptive cross-sectional study investigated the factors affecting the interest of 261 specialized assistants to continue their studies in subspecialized fields from March 2021 to March 2022. All the specialized assistants of Kerman University of Medical Sciences (KMU), whose assistantship continued until the end of March 2022, were included in the study by census method. The data collection tool was a 4-part questionnaire. 1) demographic information including 13 questions (age, gender, marital status, city where the family lives, place of residence to complete the residency course, specialized field, level of education, grade point average, parents' education, parents' occupation and having first-degree relatives with subspecialized degrees), 2) the willingness or unwillingness to continue studying in subspecialized fields and the field of interest, 3) the reasons for the assistants' interest in continuing their education, included 14 questions, and 4) the reasons for the assistants' lack of interest in continuing their education, included 14 questions.
Results: The average age of the assistants was 31.53±3.90 years old. Most of the assistants were women (57.9%). 57.5 percent of the assistants were interested in continuing their studies in subspecialized fields. The most important reason for residents' interest in continuing their studies was "increasing practical-clinical knowledge" (80.1%). The most interest in continuing education was observed in internal assistants (17.33%). The assistant's age, specialist field and having first-degree relatives with a subspecialist degree had a significant relationship with the interest of the assistants to continue studying in subspecialist fields.
Conclusion: The results showed that a significant percentage of assistants were interested in continuing their studies in subspecialized fields. Age, the assistant's specialty and having first-degree relatives with a subspecialist degree had a significant effect on this interest.

Abstract
Background: Breast cancer ranks as one of the most prevalent cancers among women worldwide and remains a major cause of mortality. The axillary lymph node (ALN) status, especially in the absence of distant metastasis, is a significant prognostic indicator in breast cancer management. Non-invasive methods, such as ultrasound, have gained prominence in the diagnostic landscape, particularly for evaluating dense breast tissue where traditional imaging may have limitations. This study was conducted to assess the diagnostic accuracy of ultrasound in detecting malignant ALNs among breast cancer patients.
Methods: This descriptive-analytical study was conducted on 150 women diagnosed with breast cancer who visited Golestan Hospital in Ahvaz, Iran, between 2021 and 2022. Patients were initially examined clinically, and subsequently, ALN evaluations were performed using a GE S6 logic ultrasound machine. Key radiologic parameters including lymph node size, morphology, cortical thickness, and vascular distribution were assessed. Stata software was used for data analysis, and pathology results were considered the gold standard to determine ultrasound’s sensitivity and specificity in detecting malignancy.
Results: We found 77.7% of the 150 patients had metastatic ALNs, indicating a high rate of lymphatic spread in this population. Ultrasound showed a sensitivity of 86.09% and a specificity of 51.52% in detecting malignant nodes. Radiological signs of cancer, like abnormal morphology and increased cortical thickness, were strongly linked to positive pathological findings. This shows that ultrasound is a useful tool for diagnosis.
Conclusion: The results indicate that ultrasound, as a non-invasive and accessible modality, can serve as a valuable diagnostic tool for identifying malignant ALNs in breast cancer patients. Integrating ultrasound with physical examination could enhance diagnostic precision, potentially reducing the need for invasive procedures such as biopsies. However, more research is necessary to establish the role of ultrasound in clinical protocols and investigate its potential to guide customized treatment strategies. Such advancements could optimize patient outcomes, enhance resource allocation, and ultimately contribute to more effective breast cancer management.

Abstract
Background: Considering the significant increase in suicidal tendencies and attempts during puberty, this study aims to investigate the effectiveness of compassion-focused therapy compared to emotion-focused therapy in increasing the resilience of female students who attempted suicide in the past has been was evaluated.
Methods: semi-experimental research was used with a pre-test and post-test design. The target population was female students of the first and second grade of high school who attempted suicide and referred to the counseling center of the General Directorate of Education, and the research was conducted from the time of data collection to the time of implementation from May 2022 to June 2023 was conducted in the counseling center under the supervision of the science and research department of Islamic Azad University, Tehran branch, was conducted and the available sampling method was selected and randomly and a total of 30 people were divided into two experimental groups (15 people) and control groups (15 people). First, Connor and Davidson's resilience questionnaire (2003) was taken from all three groups. The experimental group underwent eight 90-minute sessions of emotion-focused compassion therapy, while the control group received no intervention. After the end of the treatment sessions, the resilience questionnaire of Connor and Davidson (2003) was administered again and repeated after one month of follow-up. The collected data were analyzed using statistical tests (multivariate analysis of covariance and analysis of variance).
Results: The results obtained from the data analysis showed a significant difference in the pre-test, post-test and follow-up resilience averages in the three groups. Resilience scores for the experimental groups were significant at P < 0.05, which indicates a significant difference. Additionally, the compassion-focused therapy group showed greater improvements in resilience compared to the emotion-focused group.

Abstract
Background: Athletes are seeking ways to enhance sports performance and protect themselves from the long-term effects of exercise. One potentially effective solution is the administration of colostrum supplements. Evidence suggests that it can support immune system function by maintaining the integrity of the intestinal barrier. The aim of this study is to evaluate the impact of colostrum supplementation on athletes' immune system performance.
Methods: This systematic review searched English and Farsi databases including Medline, Scopus, Embase, ScienceDirect, Scientific Information Database, Islamic World Science Citation, Cochrane, and Google Scholar website without a time limit until November 2023. Eighteen randomized clinical trials, following the Cochrane protocol, were analyzed to assess the effects of colostrum supplementation on athletes' immune systems. The studies measured various factors, such as the amount of cytokines, concentration of serum immunoglobulins, salivary immunoglobulin, white blood cell count, neutrophil oxidative reactions, and the rate of respiratory system-related diseases in athletes during the consumption of colostrum supplements or its derivatives. The potential risks of bias in the studies were evaluated using the Cochrane Risk of Bias 2.0 tool for randomized controlled trials.
Results: The findings of these studies indicate that daily consumption of 3.2 grams of colostrum for 24 weeks can decrease the production of inflammatory cytokines caused by exercise and increase anti-inflammatory cytokines. Additionally, a daily intake of 20 grams of colostrum supplement can protect against the reduction of neutrophil function and immune responses resulting from long-term exercise. The group receiving colostrum experienced fewer upper respiratory tract diseases compared to the placebo group in studies that investigated this indicator. No significant effects on leukocyte count were observed with any dosage of supplementation, and the results of studies on other immune indicators were inconsistent.
Conclusion: Bovine colostrum can improve athletes' immune system performance by regulating immune parameters and mitigating the negative effects of intense exercise. However, the contradictory results of existing studies call for further research that examines different doses of colostrum in various sports.

Abstract
Tendon ruptures may occur as a result of acute injuries or degenerative changes in the tendons caused by aging, excessive and long-term use of the shoulders, and sudden wear and tear. This tear may be partial or completely separate the tendon from its attachment to the bone. Rotator cuff tendinopathy of the shoulder is one of the common causes in patients that affect the daily performance and quality of life. Tendinopathy problems are one of the most common problems of people who refer to medical centers, and in some people, improvement is very important because of their job position. Platelet-rich plasma has received attention due to having growth factors involved in tissue repair in tendinopathy patients. This review study examined the clinical effect of platelet-rich plasma injection in rotator cuff tendinopathy, as well as other studies comparing it with corticosteroids. A literature search was conducted in various scientific databases to obtain articles up to 2022 examining the clinical effects of PRP injection on tendinopathy. Platelet-rich plasma (PRP) is one of the products derived from blood that contains a greater number of physiological platelets. PRP contains a large amount of growth factors such as TGF-β, platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF), which play an important role in cell proliferation, cell differentiation, chemotaxis and angiogenesis. These growth factors are significantly upregulated following tendon injury and are active at different stages of the healing process. Platelet-rich plasma is an autologous source of growth factors and has been shown to be beneficial in the treatment of tendinopathy and osteoarthritis. PRP injection can be recommended as a suitable and desirable method in tendinopathy and rotator cuff tear patients, especially in adults, and can be substituted for corticosteroids. PRP is a minimally invasive treatment method that is used to treat muscle diseases and tendon injuries. In this method, blood is taken from the person, and after that, the components of the blood are separated during a process, and the platelet-enriched plasma is re-injected into the muscles and tendons of the shoulder.

Abstract
Background: Liver fibrosis is a major concern associated with long-term side effects among patients with rheumatoid arthritis (RA) treated with methotrexate. The aim of the present study was to compare the fibrosis-4 (FIB-4) index and the results of liver fibrosis severity derived from FibroScan device in rheumatoid arthritis patients who were treated with methotrexate.
Methods: The present cross-sectional study was conducted in 70 RA patients referred to rheumatology clinic of Hazrat Rasool Akram Hospital, Tehran, from July 2022 to July 2023. First, FIB-4 was calculated and the data from transient elastography, which was performed using a FibroScan device to diagnose liver fibrosis for each patient, will be compared with the results of the FIB-4 of each patient. Furthermore, the correlation between FIB-4 index and FibroScan grade with demographic characteristic, methotrexate dose and disease duration was also evaluated.
Results: The average age of patients was 59.59±11.75 and most of them (74.3%) were women. Most patients (75.71%) with a normal to mild FIB-4 index stage had a normal to mild elastography stage. of patients had normal to mild liver fibrosis. FibroScan grade were not related to the age, gender, body mass index, methotrexate dose and duration of the disease (P>0.05). The average FIB-4 was 1.25±0.6, which was not significantly related to gender, body mass index, disease duration and methotrexate dose but directly related to the age of patients (P<0.001, (CL95%, 0.51-0.53)).The correlation between FIB-4 and FibroScan grade of the patients showed a positive association, which was not statistically significant (P=0.594, r=0.06, CL95%, -0.24-0.4). The FIB-4 in normal to mild grade was 85% rejecting the moderate to severe grade in FibroScan but none of them were statistically significant (P=0.146).
Conclusion: Overall, the FIB-4 was incapable of predicting the FibroScan result. On the contrary, this case was also inconclusive and the results of FibroScan did not justify FIB-4 results of the patients. The FIB-4 cannot replace in RA patients. It is recommended to conduct future studies with a larger sample size in RA patients. |
