RESUMEN
BACKGROUND: Considering the challenges of the referral system in the family physician program and the impact of COVID-19 pandemic on the performance of the relevant ministry's programs, it is necessary to assess the performance of the referral system. This study was conducted with the aim of investigating the performance of the family physician referral system before and during COVID-19 in Golestan province. METHODS: The present repeated cross-sectional study was conducted on secondary data Recorded of 786,603 cases referred and cared by family physicians (including information on physicians' and midwives' visits, percentage of prescriptions and other information) in Golestan province from 2017 to 2022 in a census and retrospective manner. Data were collected using the reference ratio checklist and analyzed with SPSS 23 software at a significance level of less than 0.05. RESULTS: Referral to 10 types of medical specialties and 10 indicators of family physicians referral before and during COVID-19 were investigated. The highest and lowest percentages of referrals by family physicians were belonged to the surgical (17.6%) and infectious (2%) specialists before COVID-19, and internal medicine (15.07%) and urology (3%) specialists during COVID-19, respectively. Referral due to physician's diagnosis increased by 19.3% compared to before Covid-19, target group increased by 0.86%, care decreased by 2.69% and reverse referral decreased by 36.1%. The amount of population covered by rural insurance, the amount of visits to midwives, the percentage of electronic appointments in the post-Covid-19 years have changed significantly compared to before.it (P-Value < 0.05). CONCLUSION: The present study showed that the COVID-19 pandemic had a significant impact on family physician referral indicators, such as the process of referral to specialists, drug prescriptions, insurance coverage, one-time service population, and patient care, which can be used to eliminate the weaknesses and Strengthening the strengths of the programs being implemented in the face of possible pandemics is very useful and effective and can be used in the country. Finally, the results obtained from this research provide evidence to discuss the importance of the family physicians care and referral system in the face of special conditions for quality control in health policies.

BACKGROUND: Short-term exposure to PM2.5 has been associated with human health risks. However, evidence on the association between short-term exposure to PM2.5 and the risk of chronic obstructive pulmonary disease (COPD) remains limited and controversial. This study aimed to specifically assess the relationship between exposure to PM2.5 and the risk of hospitalization due to COPD. METHODS: A systematic search was conducted in PubMed, Web of Science, and Google Scholar databases from January 1, 2010 to May 1, 2022. The odds ratio (OR) statistic was calculated as a common measure of effect size. Publication bias was also examined in all eligible studies on COPD hospitalization using funnel plots and Egger's test, as well as trim-and-fill method for missing studies on COPD hospitalization. RESULTS: A total of 19 studies were included in this meta-analysis. Random-effects models were plotted to calculate the pooled effect size by measuring OR (χ2 = 349.95; df = 18; I2 = 94.86%; P = 0.007; Z = 2.68; P < 0.001). A 10-mg/m3 daily increase in PM2.5 concentration was associated with a 1.6% (95% CI: 0.4-2.9%) increase in COPD hospitalization. There was no publication bias regarding the association between COPD hospitalization and PM2.5 (bias = 1.508; 95% CI: -1.475, 4.491; t = 1.066; P = 0.301). The subgroups of age ≥ 65 years and Asian countries were associated with an increased risk of COPD hospitalization. Besides, higher risks were estimated in the subgroups of studies performed in the warm season, case-crossover studies, studies with three lag days, and studies without adjustments for humidity and temperature confounders, with very small heterogeneity. CONCLUSION: Evidence suggests that short-term exposure to PM2.5 increases COPD hospitalization. Further studies are needed to understand the mechanism of the association between PM2.5 and COPD for reducing air pollution, which can be beneficial for COPD patients.

BACKGROUND: Medical universities are responsible for educating and training healthcare workers. One of the fields significantly impacted by the pandemic is medical education. The aim of this study is to identify strategies for enhancing e-learning for active learning and finding solutions for improving its quality. METHODS: This mixed-method (quantitative-qualitative) research was conducted in 2023 at three selected universities in Mazandaran Province. In the quantitative phase, 507 students participated via stratified random sampling using a standard questionnaire. In the qualitative phase, data were collected through semi-structured interviews with 16 experts until data saturation was achieved. SPSS 21 and MAXQDA 10 software were used for data analysis. RESULTS: In the multivariate regression analysis, an increase of one point in the dimensions of student-teacher interaction, active time, immediate feedback, and active learning corresponded to an average increase in learning scores of 0.11, 0.17, 0.16, and 1.42 respectively (p≤0.001). After the final analysis in the qualitative phase, four main domains (infrastructure, resources, quantity of education, and quality of education) and 16 sub-domains with 84 items were identified. CONCLUSIONS: The greatest challenge in e-learning is the interaction and cooperation between students and teachers. The implementation of the identified strategies in this research could provide useful evidence for policymakers and educational administrators to implement interventions aimed at addressing deficiencies and enhancing e-learning.

BACKGROUND: Preparation and financing of treatments, control of disease by limited resources, are known as the most important challenges encountered by the policy-makers involved in an epidemic outbreak. Therefore, the present study was conducted to analyze the policy responses of Babol University of Medical Sciences (BUMS) to Coronavirus (COVID-19). METHODS: A qualitative study was performed to investigate the policy responses of BUMS to COVID-19 in Babol of January to March, 2021. The statistical population included the experts, pundits, policy-makers and planners involved in four areas of management, treatment, healthcare, and health donation. Data collection was done according to interviews and policy documents, and the obtained data were analyzed based on the Walt and Gilson's policy triangle. RESULTS: There are five main themes to names: policy context, policy analysis, policy-making process, actors and stakeholders and 16 sub-themes. After several rounds of revision, the text of the interviews and policy documents were tagged and finally, various issues related to sub-themes were extracted. Also, two sub-themes entitled (improving the policy framework, People's participation) were obtained from the strategies to reduce the incidence of Covid-19 theme. CONCLUSIONS: (BUMS) was able to use the capacities and skills of experienced physicians, specialists and nurses to respond to patients awaiting treatment. Therefore, most of the policies were aimed at patient care and treatment. The lack of financial resources was compensated by health donors. But the (BUMS) could not use the power of the city government to control traffic and comply with health protocols and prevent infections. It was mainly the formulation and implementation of irregular and unstable policies.
RESUMEN
BACKGROUND: The gap between knowledge and practice, along with postponing or not implementing research findings in practice and policy-making, is one of the reasons for low-quality services. Hence, this study aimed at presenting a model of knowledge implementation in health system management in Iran. METHODS: The present two-phase study was first performed qualitatively using a directive content analysis approach based on the Promoting Action on Research Implementation in Health Services (PARIHS) model. The researchers extracted the barriers and facilitators by conducting semi-structured individual interviews. Then, in a three-stage Delphi study, 25 health experts determined the barrier removal strategies. Data were analysed using MAXQDA10 software. RESULTS: The content analysis of the interviews led to the emergence of 1212 codes under three categories of evidence, context and facilitation. The findings indicate that health managers make fewer decisions based on research findings. Instead, they make decisions regarding the experiences of service providers and organization data. In addition to the subcategories in the PARIHS model, the researchers extracted political, social and administrative factors under the context category. The relationships between the features of evidence, context, facilitation, barriers and strategies were presented in the final model. CONCLUSION: The presented model comprehensively emphasizes the evidence resources, context preparation, and facilitation of the knowledge implementation process.

BACKGROUND: Inappropriate ways of health services purchasing for cancer patients can be challengeable and costly and seriously affect the access to health services and outcomes. This study aimed at Factors affecting health services strategic purchasing for breast cancer patients. METHODS: As a mixed study, this research was conducted in Iran in 2020. In the qualitative phase, 21 specialists and professionals in the field of health services purchasing were purposefully selected and interviewed. After data saturation, interviews were analyzed with the framework analysis and a structured questionnaire was made based on these analyses. 400 breast cancer patients were selected by randomized sampling and completed the questionnaire. Data were analyzed with SPSS23 in p < .05. RESULTS: The highest mean rate of the three main categories belonged to "insurance trusteeship" (4.71 ± .35), followed by "supply management" (4.48 ± .27) and "financial performance" (4.48 ± .37). There were significantly differences between the mean rates of the main categories and the cut-off point (p < .001). In addition, "insurance trusteeship" ranked first (2.58), followed by financial performance (1.77) and supply management (1.65). CONCLUSION: Of main components in health services strategic purchasing for breast cancer patients, insurance trusteeship, supply management, and financial performance ranked first to third, respectively. Therefore, healthcare policy-makers should consider the placement of insurance trusteeship and coordinate between purchasers and providers for making reform in the health system.
RESUMEN
BACKGROUND: The global burden of road injuries is known to follow complex geographical, temporal and demographic patterns. While health loss from road injuries is a major topic of global importance, there has been no recent comprehensive assessment that includes estimates for every age group, sex and country over recent years. METHODS: We used results from the Global Burden of Disease (GBD) 2017 study to report incidence, prevalence, years lived with disability, deaths, years of life lost and disability-adjusted life years for all locations in the GBD 2017 hierarchy from 1990 to 2017 for road injuries. Second, we measured mortality-to-incidence ratios by location. Third, we assessed the distribution of the natures of injury (eg, traumatic brain injury) that result from each road injury. RESULTS: Globally, 1 243 068 (95% uncertainty interval 1 191 889 to 1 276 940) people died from road injuries in 2017 out of 54 192 330 (47 381 583 to 61 645 891) new cases of road injuries. Age-standardised incidence rates of road injuries increased between 1990 and 2017, while mortality rates decreased. Regionally, age-standardised mortality rates decreased in all but two regions, South Asia and Southern Latin America, where rates did not change significantly. Nine of 21 GBD regions experienced significant increases in age-standardised incidence rates, while 10 experienced significant decreases and two experienced no significant change. CONCLUSIONS: While road injury mortality has improved in recent decades, there are worsening rates of incidence and significant geographical heterogeneity. These findings indicate that more research is needed to better understand how road injuries can be prevented.

The aims of this study are to determine the replacement rate of damaged hepatocytes by donor-derived cells in sex-mismatched recipient patients with thalassemia major and to determine whether co-transplantation of mesenchymal stem cells and hematopoietic stem cells (HSCs) can alleviate liver fibrosis. Ten sex-mismatched donor-recipient pairs who received co-transplantation of HSCs with mesenchymal stem cells were included in our study. Liver biopsy was performed before transplantation. Two other liver biopsies were performed between 2 and 5 years after transplantation. The specimens were studied for the presence of donor-derived epithelial cells or hepatocytes using fluorescence in situ hybridization by X- and Y-centromeric probes and immunohistochemical staining for pancytokeratin, CD45, and a hepatocyte-specific antigen. All sex-mismatched tissue samples demonstrated donor-derived hepatocyte independent of donor gender. XY-positive epithelial cells or hepatocytes accounted for 11 to 25% of the cells in histologic sections of female recipients in the first follow-up. It rose to 47-95% in the second follow-up. Although not statistically significant, four out of ten patients showed signs of improvement in liver fibrosis. Our results showed that co-transplantation of HSC with mesenchymal stem cells increases the rate of replacement of recipient hepatocytes by donor-derived cells and may improve liver fibrosis.

For finding better method of acute myeloid leukaemia (AML) induction, we designed a prospective clinical trial to find a more effective regimen with least toxicity for induction therapy of AML. Hence, we examined different accepted doses of daunorubicin and their outcomes. Total of 114 patients were included in the study. Fifty-five patients received 60 mg/m2 of daunorubicin (arm 1) 1 h IV infusion for 3 days, and the remaining 59 received 80 mg/m2 (arm 2) 1 h IV infusion for 3 days. Continuous infusion of 100 mg/m2 /day of cytosine arabinozide IV for 24 h for 7 days was given in both groups. Complete remission rate was 77.78% in group 1 and 76.92% in group 2 (p = 0.92). One-year overall survival was 55.85% [standard error (SE) = 8.05%] in arm 1 and 57.94% (SE = 7.32%) in arm 2. Median follow-up time was 11.1 (SE = 1.43) and 10.28 (SE = 1.29) months, respectively. One-year disease-free survival was 64.41% (SE = 7.39%) in arm 1 and 54.86% (SE = 7.53%) in arm 2. Complete remission, overall survival and disease-free survival were statistically the same in both groups (p = 0.92, 0.697, 0.31). Toxicity and safety profile were similar in two groups but need to transfusion was higher in arm 2. Febrile neutropenia, days of antibiotics consumption and invasive fungal infection prevalence did not show any difference. Mean transfused packed cells and platelets rate were higher in the group that received higher dose of daunorubicin. Considering these results, we found that 60 mg/m2 of daunorubicin would be more rational and as effective with lower toxicity to 80 mg/m2 in induction therapy of AML patients at least as scheduled in our trial.

The present work is aimed at finding variants associated with Type 1 and Type 2 diabetes mellitus (DM) that reside in functionally validated miRNAs binding sites and that can have a functional role in determining diabetes and related pathologies. Using bioinformatics analyses we obtained a database of validated polymorphic miRNA binding sites which has been intersected with genes related to DM or to variants associated and/or in linkage disequilibrium (LD) with it and is reported in genome-wide association studies (GWAS). The workflow we followed allowed us to find variants associated with DM that also reside in functional miRNA binding sites. These data have been demonstrated to have a functional role by impairing the functions of genes implicated in biological processes linked to DM. In conclusion, our work emphasized the importance of SNPs located in miRNA binding sites. The results discussed in this work may constitute the basis of further works aimed at finding functional candidates and variants affecting protein structure and function, transcription factor binding sites, and non-coding epigenetic variants, contributing to widen the knowledge about the pathogenesis of this important disease.

RESUMEN
Background: Breast cancer commonly occurs in women, and male breast cancer makes up less than 1% of all cases of breast cancer. The limited prevalence of male breast cancer has led to decreased attention being paid to this condition, resulting in its diagnosis occurring at later ages and at more severe disease stages. Objectives: This study evaluates the demographic and clinicopathological characteristics of male patients diagnosed with breast cancer who visited the northern region of Iran from 1992 to 2023. Methods: This descriptive study reviewed data from 58 cases of male breast cancer between 1992 and 2023. The study aimed to examine and describe the information connected to these patients. The data were analyzed with SPSS.22 set at P value less than 0.05. Results: The mean age of the patients examined was 62.10±13.40 years, while their mean BMI was 27.08±4.95. The study found no statistically significant correlation between BMI with stage and kinds of recurrence, including metastasis and local recurrence (P>0.05). The right and left breast involvement rates were equal (48.28%) in 28 cases, and 2 cases (3.40%) had bilateral involvement. The bone was the predominant site of metastasis, accounting for 69.23% of cases. The analysis revealed no significant correlation between stage and metastasis (P=1.000) or local recurrence (P=0.543). Most metastasis and all the local recurrence were observed in stages 3 and 4. Conclusion: Male breast cancer mainly occurs in older age and is diagnosed in the advanced stages of the disease. Therefore, it is recommended to inform men and develop suitable screening programs, especially in high-risk families.
RESUMEN
Background: Examining the raw and standardized mortality rates is the primary strategy for improving life expectancy and human health in society through identifying risk factors and dealing with the factors that cause them. Objectives: This study examined the trend of mortalities due to traffic and nontraffic accidents. Methods: This cross-sectional study examines the registered mortalities during the years 2016-2022 in the form of a census in the health department's death registration and classification system. Mortality was analyzed as raw and standardized mortality in each 100 000 population. Results: Out of 18 265 deaths during 2016-2022, 1305 (7.15%) were related to accidents and incidents. The age-standardized total mortality rate in the first year was 32.9, and in the final year of the study, it was 33.3 per 100 000 people; although there are fluctuations, this trend is upward (P.trend=0.021). Also, the age-standardized traffic death rate in the first year is 19, and in the final year is 12 per 100 000 people; this decreasing trend was not statistically significant (P.trend=0.061). The incidence of age-standardized intentional nontraffic deaths was 1.7 in the first year of the study interval and 9.8 in the last year in 100 000 people, which showed an upward trend (P.trend<0.001). Conclusion: In light of the generally increasing trend of accidents, especially nontraffic accidents, universal and well-rounded measures are necessary for safety matters and reducing mortality.
RESUMEN
The aim of this study was to determine the challenges and opportunities of virtual education during the COVID-19 pandemic. This study was conducted in 2022-2023 with a mixed method. During the quantitative phase, we chose 507 students from Mazandaran Province medical universities (both governmental and non-governmental) by stratified random sampling and during the qualitative phase 16 experts were collected by purposive sampling until we reached data saturation. Data collecting tools consisted of questionnaires during the quantitative phase and semi-structured interview during the qualitative phase. Data was analyzed using SPSS21 and MAXQDA10. Mean scores of the total score was 122.28±23.96. We found a significant association between interaction dimension and background variables (P < 0.001). The most important privilege of virtual education is uploading the teaching material in the system so that students can access the material constantly and the most important challenge regarding virtual education is lack of proper network connection and limited bandwidth. Virtual education proved to be a suitable alternate to traditional methods of medical education during the COVID-19 pandemic in theoretical topics, we recommend that educational policymakers would take the necessary actions to provide the requirements and facilities needed to improve the quality of virtual education.

Background: Breast cancer is one of the most important causes of cancer deaths in women. The present study was conducted to determine the relationship between demographic factors and known risk factors with breast cancer in women aged 30-69. Method: This case-control study was conducted with two matched and unmatched control groups. Three hundred fifty women aged 30-69 with breast cancer, 350 age-matched women without cancer, and 350 not age-matched women were included in the study. Controls were selected from the records of women whose breast cancer screening results were normal. Study subjects were evaluated regarding the risk factors for breast cancer. The data collection tool was a checklist including the risk factors investigated in the integrated health system. The collected data were analyzed utilizing SPSS22 software at a significance level of less than 0.05. Results: The average age in the case group was 46.63±11.77 years and 49.61±8.39 in the unmatched control group. The average age of marriage in the case group was 21.54±4.31, and the average age of women at first pregnancy in the case group was 24.06±3.39 years. In the case group, 163 people (46.57%) lived in the city, 221 people (63.14%) were over 40 years old, and 337 people (96.28%) were married. In multivariate analysis, the variable 'age of marriage' 0.821 (0.691-0.976) and 'age of first pregnancy' 1.213 (1.020-1.443) showed a significant relationship with breast cancer which were observed as predictors of breast cancer in comparison to the unmatched control group (P-value <0.05). Conclusion: The age of the first pregnancy and the type of delivery were observed as predictors of breast cancer. Therefore, by performing breast cancer screening in women who are exposed to these risk factors, early diagnosis of the disease and increasing the speed of their treatment can be significantly helped.
RESUMEN
Background: Early and minimally invasive detection of epidermal growth factor receptor (EGFR) mutations in non-small cell lung cancer (NSCLC) patients is a promising tool to select patients for targeted therapy in order to improve their prognosis. This study aimed to identify a sensitive, cost-effective, and easily accessible noninvasive method for detecting the EGFR-targetable mutations in the plasma exosomal DNA (exoDNA)+ of patients with NSCLC. Methods: This retrospective observational study was conducted over 10 months, from December 2022 to October 2023, at Masih Daneshvari Hospital in Tehran, Iran. A total of 30 patients with stage II-IV NSCLC and targetable mutation in the EGFR gene were included in the study. Nested PCR and Sanger sequencing were used to evaluate EGFR mutations in the DNA extracted from circulating exosomes. Results: The study found a sensitivity of 76.6% for EGFR mutation detection on exoDNA compared to tissue results. No significant impact was observed based on tumor staging, histology, mutation type, smoking status, gender, or age. Conclusion: Therapeutically targetable driver mutations in the EGFR gene can be accurately detected using nested PCR followed by direct sequencing of plasma exoDNA from patients with NSCLC. This approach facilitates timely and more personalized treatment for NSCLC patients, ultimately improving patient prognosis. Additionally, this method reduces the reliance on invasive tissue biopsies and their associated complications.

BACKGROUND: Cancers, especially Upper Gastrointestinal Cancers (UGCs), pose a substantial burden on society, particularly in developing nations. Golestan province, Iran, is known for its high UGC rates globally. AIMS: This study delves into the disease burden of UGCs in the eastern part of Golestan province. METHODS AND RESULTS: This study was conducted using the results of the Golestan cohort study. 2711 patients participating in this cohort, who visited Atrak Clinic during 2001-2020, participated in this study. After excluding patients with incomplete records, 2481 patients were included in the study. To compute the metrics of years of life lost (YLL), years of life lived with disability (YLD), and disability-adjusted life years (DALY), we utilized the World Health Organization's standard life table, stratified by age and gender. The majority of UGC patients in our study were married (81.8%), had limited formal education (82.6%), and were predominantly male (61.1%). A substantial proportion resided in suburban areas (85.8%), and over half of the patients (52%) reported a history of drug addiction. The mean age at diagnosis for men was 65.76 years with a standard deviation of 11.34, while for women, it was 64.38 years with a standard deviation of 11.66. Regarding disease impact, YLL, YLD, and DALY for men were 21 240, 1956, and 23 196 (307.8 per 100 000), respectively. For women, these figures were 15 609 for YLL, 1367 for YLD, and 16 976 (223.1 per 100 000) for DALY. CONCLUSION: After the increasing trend of the burden of UGCs in Golestan province in the early years of the study, this rate has been decreasing in recent years. Effective strategies necessitate collaborative efforts across various sectors to alleviate this burden, focusing on preventive measures, timely diagnosis, and well-coordinated therapeutic interventions.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) has been established as a promising treatment in acute myeloid leukaemia (AML). Several studies have been performed to minimize the toxicity of HSCT in children without impairing the efficacy. We report our long-term results of HSCT in pediatric AML patients using non-total body irradiation conditioning regimen. PROCEDURE: From May 1991 to June 2010, 133 pediatric patients with AML (age<15 y) who were referred to our institute underwent autologous (auto-) or allogeneic (allo-) HSCT. The conditioning regimen consisted of oral busulfan plus etoposide in auto-HSCT patients and oral busulfan plus cyclophosphamide in allo-HSCT patients. RESULTS: Overall survival (OS), leukemia-free survival (LFS), probability of relapse, and transplantation-related mortality at 3 years were 67.6%, 62.2.5%, 27.3%, and 10.1%, respectively. There was no significant difference between allo-HSCT and auto-HSCT groups. In multivariable analysis using Cox proportional hazards regression model, male sex was associated with significantly improved OS (P<0.001) and LFS (P=0.022). An age ≤3 years was associated with higher relapse (P=0.034) and worse OS (P=0.001) and LFS (P=0.014). CONCLUSIONS: The role of allo-HSCT in pediatric AML patients in first complete remission is uncertain. Further randomized studies are recommended to clarify the optimal postremission therapy in these patients.

BACKGROUND: The cancer registry system is an important part of the cancer control program. Improper coding of cancers leads to misclassification and incorrect statistical information about cancer. Therefore, in this study, the main objective of the qualitative analysis was the accuracy in assigning the codes to the pathological reports in the centers responsible for cancer registry. METHODS: This study was descriptive, retrospective and applied. The data source in this study included 15,659 pathology reports received during the years 2017-2019 in the population-based cancer registry centers of Mazandaran province. Out of 1800 reports, 1765 samples of reports were selected and analysis was done on them by stratified random sampling method. A researcher-made checklist was used to collect data, and the Kappa agreement coefficient and Cohen's agreement percentage were presented to check the accuracy of the reports. STATA13 was used for data analysis. RESULTS: 1150 of 1765 pathology reports (65.0%), did not have a topographic, morphological and behavioral codes and 410 (23.2%) had grade codes. The Kappa coefficient in reports with a topography code was 0.916 and with a morphology code it was 0.929, respectively. In behavior coding, the highest agreement is in the category of benign cancers at 65.2% and in grade coding in the category without grade is 100%. CONCLUSION: The most reports were on carcinoma morphology, and the Kappa coefficient in morphology codes has almost complete reliability. In terms of behavior coding, there was the most agreement in the category of benign cancers. The Kappa coefficient in given behavior codes has low reliability.
