One of the most important issues related to sports spaces in schools is the health and safety status of sports places. The purpose of this research was to investigate the safety and health components of schools in Zabol City, Iran.

In this descriptive study, 100 government and non-government primary schools were examined using a random stratified sampling method. To collect data, a questionnaire was developed based on input from the authors of related articles and approved by health and safety experts. The reliability of the questionnaire was established with a Cronbach's alpha coefficient of 0.85. The data were analyzed using independent t-test and descriptive statistical methods with SPSS software.

Regarding the safety conditions of the field, 48 schools (48%), equipment 50 schools (50%), privacy and lines, platforms and coverings 45 schools (45%), and the overall health of the sports fields 52 schools (52%) were in average condition. Notably, the health component of the sports fields was found to be in poor condition. In girls' and boys' schools, no statistically significant differences were observed among the investigated components. However, a disparity was noted between government and non-government schools, with non-government schools exhibiting unfavorable conditions regarding the assessed indicators.

The health and safety situation of sports spaces in schools of Zabol City is worrying, so that in terms of the safety of privacy and lines component, public and girls' schools were at an average level, and most of the private and boys' schools were at a poor condition. Moreover, regarding the compliance with health principles in girls’ and boys’ public and private schools, most of the schools were at a poor condition. Therefore, it is suggested that the education and training system in Zabol City will improve the health and safety level of schools in this city by holding orientation classes for managers, physical education instructors, and teachers in the fields of health and safety.

Patient safety is one of the fundamental principles of health care. The investigation of patient safety culture is a step towards providing safe conditions for patient care. This study aims to explore the Iranian intensive care unit (ICU) nurses’ experiences of patient safety culture in hospitals.

This is a qualitative study using the conventional content analysis method. Participants were 18 ICU nurses from three hospitals affiliated to Tehran University of Medical Sciences in 2021-2022, who were selected using a purposive sampling method. In-depth semi-structured interviews was carried to collect data. Data were analyzed using Graneheim and Lundman’s content analysis method.

Three themes were extracted: Individual (sufficient knowledge and skills, observance of professional values, work experience), interpersonal (inter-departmental communication, intra-departmental communication), and organizational (supportive management versus punitive response to errors, equipment safety, irrational workload, and employee empowerment).

The results revealed that the concept of patient safety culture in Iranian hospitals is multidimensional (individual, interpersonal, and organizational). Integrating effective patient safety culture into all parts of the organization should be the priority of hospital management programs. To promote awareness in the field of patient safety culture while holding regular training courses, hospital managers should encourage non-punitive responses to errors and teamwork to clarify the performance and expectations of the health system about improving patient safety.

Considering the high number of pedestrian accidents in Marand and their subsequent physical, psychological, social, and economic damages on the individual, family, and society, the current study was conducted to investigate the relationship between the socioeconomic status and traffic behavior of pedestrians.

This descriptive-analytical study was conducted in Marand, one of the major cities in East Azerbaijan province of Iran in 2018-2019. The statistical population of the research included all the pedestrians of Marand. The statistical sample consisted of 515 pedestrians who were chosen from individuals who walked to the health centers. Data was collected using the pedestrian behavior questionnaire and the socioeconomic status questionnaire. Data analysis was conducted using SPSS software (version 23), which included descriptive statistics, independent t-test, and one-way analysis of variance (ANOVA).

The mean (standard deviation) of the total score of pedestrian traffic behavior in this study was 82.07 (7.80). The results of the independent t-test showed that the average score of aggressive behavior had a significant relationship with gender. As such, men had better traffic behaviors than women pedestrians. Based on the results of one-way ANOVA, the mean score of positive behaviors was significantly different in various age groups. Married pedestrians had fewer distracted behaviors than single pedestrians. Also, in all dimensions of traffic behavior, with the improvement of the socioeconomic status, the average score of traffic behavior increased. However, this increase was significant only in the subscales of adherence to traffic rules, positive behaviors, and distraction.

According to the results of this study, pedestrians who had a lower socioeconomic status showed more unsafe behaviors while crossing the road. Also, unsafe behaviors were more common among female pedestrians and young age groups. Therefore, measures such as implementing educational and environmental interventions considering pedestrians’ demographic characteristics should be adopted to improve their traffic knowledge and behavior.

Considering the systemic inflammation and disorder in the immune system with increasing age and obesity, as well as the effect of aerobic training and omega-3 in modulating inflammation and immunity, the aim of the present study was to determine the effect of aerobic training and omega-3 on the expression of IL-17 and IL-22 in visceral adipose tissue of elderly rats fed with a high-fat diet.

In this experimental study, 40 male Wistar rats (mean weight : 148.82 ± 18.24 grams) were divided into 5 groups: Normal Diet (ND), High-Fat Diet (HFD), High-Fat Diet-Training (HFDT), High-Fat Diet-Omega3 (HFDω3), and High-Fat Diet-Training-Omega3 (HFDTω3). The supplement groups received 1 g of omega-3 (per kg of body weight) orally during the intervention period. An aerobic training program, including running on a treadmill with an intensity of 50-60% oxygen consumption (VO2max), was performed 5 days a week for eight weeks. Forty-eight hours after the research protocol, gene expression levels in fat tissue were measured by the real-time PCR method.

HFD induction was associated with an increase in the expression of IL-17 and IL-22 (p = 0.0001). A significant decrease was observed in IL-17 and IL-22 in HFDT (p = 0.026 and p = 0.037, respectively), HFDω3 (p = 0.035 and p = 0.044, respectively), and HFDTω3 (p = 0.0001 and p = 0.0001, respectively) compared to HFD; and HFDTω3 compared to both HFDT (p = 0.049 and p = 0.039, respectively) and HFDω3 (p = 0.037 and p = 0.033, respectively).

Aerobic training and omega-3 consumption can reduce visceral adipose tissue IL-17 and IL-22, immune disorders, and inflammation induced by HFD in aged rats. However, the effect of combining exercise and supplementation is better.

Nowadays, medical devices are widely used around the world. In every country, the safety of these devices is inextricably related to public health and security. Despite all these sensitivities and legal oversight, issues such as lack of transparency in the medical device supply chain, lack of real feedback from incidents and clinical reports related to these devices, and consequently the failure to update risk management systems and improve the quality of these devices, resulting in increased safety risks for users/patients. Therefore, the development and implementation of an effective post-market surveillance and management system for medical devices is essential.In this article, in addition to a review of some applications of blockchain technology in the health sector, the requirements and structural framework for an information and management system for post-market surveillance of medical devices based on this technology were also presented. This system was developed with the approach of tracking medical devices to enhance transparency, provide rapid information dissemination, and reduce the rate of adverse incidents, and clinical reports related to these devices throughout their supply chain. A blockchain-based post-market surveillance system for medical devices could provide all stakeholders with valuable and real recommendations and information in the form of smart contracts by ensuring complete informational transparency throughout the supply chain. Blockchain technology could be used by regulatory and oversight organizations to effectively monitor and manage the performance of medical devices, ensuring greater transparency, and thereby guaranteeing enhanced safety and quality for stakeholders.

As the use of botulinum toxin to treat glabellar lines increases, particularly in Iran, where foreign products (e.g. Dysport) are relatively expensive, it becomes important to compare the efficacy, side effects, and duration of action of two locally produced botulinum toxin brands, Masport® and Dyston®. This study seeks to assess and compare the treatment results of these two medications.

In this cross-sectional, descriptive, retrospective study, the medical records of 81 patients who visited Razi Dermatology Hospital for the treatment of moderate to severe glabellar lines were reviewed. Data related to patient satisfaction, duration of action, and side effects of Masport® and Dyston® botulinum toxin were collected and analyzed via a questionnaire.

The mean satisfaction score was 7 for the Dyston® group and 7.7 for the Masport® group, with no statistically significant difference between the two groups (P=0.142). Additionally, the mean duration of action was 3.5 months for Dyston® and 3.8 months for Masport®, with no significant difference observed. Headache was the most common side effect reported, with no other major adverse events noted. Furthermore, there was no statistically significant difference in the incidence of side effects between the two groups.

The findings of this study indicate that both Dyston® and Masport® have similar efficacy and safety profiles. The choice between them can be primarily based on cost and patient or physician preference rather than any significant therapeutic differences. Larger studies are recommended to further validate these findings.

Standard is a license for rules, guidelines or features for activities that is approved for repeated use and its purpose is to achieve a desirable level of order and compliance with laws. Therefore, it should be said that the standard is based on the results of science, techniques and experiences of different people and organizations. Standardization are the important and necessary processes for the sustainable development of various industries and technologies, and their formulation and implementation are vital for the sustainable development of various technologies. The purpose of standardization by the International Standard Organization is to improve quality, safety, efficiency, reliability, interchangeability and compatibility. As a product related to people's health; medical laser equipment must also have standards so that its performance can be trusted. The goal of standardization of medical equipment is to achieve products with minimum requirements for safety and efficiency. This article considers the standards of medical laser equipment, which are essential for users to be familiar with. Standards act as frameworks for the design and production of medical equipment and ensure the safety of patients. They include specific requirements for safe design, safety tests and ease of use. By complying with these standards, manufacturers can produce high quality and efficient products and receive the relevant certificates. Medical laser products are in the range of certain wavelengths and due to optical hazards, they must meet certain safety requirements that are included in the standards introduced in the article. Standards and requirements related to medical electrical equipment have also been addressed, including special requirements for laser and non-laser products. And to ensure the safety of users, protective glasses and their specifications, which must be in accordance with international standards, are described. Compliance and familiarity with these standards are necessary for all operators of the medical equipment industry to ensure product is safe and have good quality.

Casirivimab/imdevimab and bamlanivimab are monoclonal antibodies that are used in the treatment of patients with COVID-19. The aim of the present study was to compare the effectiveness and safety of the casirivimab/imdevimab versus bamlanivimab in COVID-19 patients through a systematic review and meta-analysis.

A systematic search was conducted in PubMed, Scopus, Cochrane Library, and Web of Science databases to identify relevant articles up to March 2024. Moreover, a manual search was performed in the sources of primary review and key studies. There was no restriction on the language of the studies. The risk of bias of the studies was conducted using the ROBINS-I tool. Data analysis was performed using Review Manager Software version 5.4.

A total of 10 observational studies involving 10695 patients were included in the study. The results of the meta-analysis showed that casirivimab/imdevimab significantly reduced the hospitalization rate compared to bamlanivimab (odds ratio [OR]: 0.56, %95, 0.40-0.79, P<0.001). However, there was no significant difference between casirivimab/imdevimab and bamlanivimab groups in terms of mortality rate (OR: 0.53, %95, 0.25-1.13, P=0.10), emergency department visit (OR: 0.91, %95, 0.71-1.17, P=0.48), ICU admission (OR: 0.65, %95, 0.33-1.26, P=0.20), mechanical ventilation (OR: 0.28, %95, 0.05-1.54, P=0.14) and adverse events (OR: 0.44, %95, 0.15-1.34, P=0.15).

The results of this meta-analysis showed that there is no difference between casirivimab/imdevimab and bamlanivimab in terms of clinical effectiveness and safety. However, casirivimab/imdevimab has better effectiveness compared to bamlanivimab in reducing hospitalization rates in the patients with COVID-19.

Cytokines play an essential role in regulating the interaction of immune cells in diabetes and infections such as toxoplasmosis. This study was conducted to investigate the serum levels of Interleukin-6 (IL-6) and Transforming Growth Factor-Beta (TGF-β) in diabetic patients with toxoplasmosis.

This study was conducted in Zabol City on patients with type I and type II diabetes, both with and without toxoplasmosis. The serum levels of target cytokines were measured using the ELISA method. Data analysis was performed using one-way ANOVA, and chi-square test was utilized to examine demographic indices.

A significant increase in TGF-β levels was observed in the group with type II diabetes and toxoplasmosis. Additionally, a slight rise in serum IL-6 levels was noted in the group with type I diabetes. However, the level of TGF-β was decreased in this group.

The present study revealed that an increase in TGF-β and a decrease in IL-6 in patients with type II diabetes and toxoplasmosis may indicate a reduction in inflammation within this specific group.

In radiographic imaging using X-rays, due to the presence of radiation sensitive organs, especially the reproductive organs (risk of cancer and genetic consequences), it is necessary that protection methods for them against ionizing radiations be carefully protected. Therefore, the present study was designed and implemented with the aim of determining protection methods for reproductive organs in radiology centers.

Methods & Materials: 

This study was conducted as a review – narrative type by using key phrases and words with the Persian and English keyword equivalents of "X-ray imaging", "pelvic shields", "ionizing radiation protection", "reproductive organ safety", "silicon rubber-lead composites" in Google Scholar, ScienceDirect databases without any time limitations and in Persian and English languages separately by two researchers. 121 full-text articles were evaluated based on the validated Newcastle-Ottawa and AMSTAR checklists and 24 of them were included in the study.

Contact shields were used more frequently and their size and shape depended on the patient's age and gender. Effective use of shields involves not only their placement but also their regular checks to prevent possible damages. Damaged shields, even if used correctly, do not fulfill their protective role. For pelvic radiography, a bismuth shield can reduce the patient's received dose without affecting image quality.

The research emphasizes the effectiveness of protecting the reproductive organs by using healthy silicon shields in reducing radiation dose without negatively impacting the diagnostic value.

 Textile industries have various types of hazards that cause accidents. One of the ways to prevent workplace accidents is to identify hazards and evaluate them. Therefore, the present study aimed to evaluate the hazards of one of the textile companies using the Failure Mode and Effects Analysis (FMEA) method.

 This was a descriptive-cross-sectional study, and the FMEA method was used to conduct the study. In this study, two dyeing and rolling halls in the textile industry were evaluated. After calculating the Risk Priority Number (RPN), the hazards were ranked, and the necessary corrective actions were proposed. All stages of this research were conducted in accordance with ethical and research standards.

 In this study, 145 root causes of potential hazards were identified, of which 71 were recognized as high-risk hazards. The highest risk score was related to the non-functioning of the emergency stop switch. The lowest risk score was related to the steam leakage from steam pipes. The most hazardous activity was found to be the printing of dyes on the fabric. Events leading to death and amputation had the highest frequency.

 The results showed that after identifying the sources of error, it is possible to prevent the failures and increase the efficiency of the process by preventing damage to materials, operations, and personnel. The present study considers the FMEA method effective in assessing the hazards in the textile company. The results of this method can also be used to reduce the risk level to an acceptable level.

One of the questions that always arises in the minds of researchers, especially young researchers, is what pattern the progress of science follows in their field of expertise and what is the direction of the studies. The purpose of this study is to analyze the content of the studies published from 2011 to 2022 in Persian scientific journals in the field of workplace safety and determine the direction and scientific process of studies in this field.

All the studies published from the years 2011 to 2022 in the Persian scientific research journals ”Iran Occupational Health”, “Occupational Health and Safety”, “Occupational Health Engineering”, ”Iranian Journal of Ergonomics”, “Occupational Medicine” and “Occupational Health and Health Promotion” were gathered using census method from the websites of the journals. In total, 595 published articles were categorized according to the thematic codes determined by the opinion of experts, the theme of “risk analysis, assessment, and risk management” had the highest percentage of frequency (18.66 percent), while the theme of “safety application in other industries or specific workplaces” had the lowest frequency of percentage (0.34 percent). Approximately 50 percent of the variance of the published studies explained the themes of “risk analysis, risk assessment, and management”, “inspection, analysis and modeling of accidents”, “human error and safety”, “social, organizational factors, culture, safety climate, and behavior-based safety”.

The existing trends emphasize the importance of learning lessons from accidents as a reactive approach and risk management, human factors, and behavioral aspects in safety interventions as a preventive approach. The research development of the country’s safety at the workplace should be further improved with new policies in different fields while taking advantage of international scientific advances on the specific functions and challenges of the country and with a problem-oriented approach.

This study aims to explore the application of the Delphi method in ranking health, safety, and environmental (HSE) management indicators at the municipal waste landfill in Mashhad.

Initially, relevant criteria and indicators were identified using the Delphi method and a survey of experts, who assigned scores ranging from 1 to 9. Subsequently, the criteria and indicators were prioritized by employing the Analytic Hierarchy Process (AHP) and based on the opinions of 15 experts through pairwise comparisons. The analysis and synthesis of indicators were facilitated using statistical software, such as Expert Choice. 

The highest scores across all three categories pertained to the safety of the burial process, integrity of burial cells, management and treatment of sanitary sewage, leachate collection systems, soil contamination via leachate, control of traffic noise and operations, and adherence to slope guidelines. Conversely, the lowest scores across all categories were associated with the safety of facilities, training, safety of equipment, warning signs, gas collection, and extraction wells, prohibition of entry and animal presence, daily spraying operations aligned with wind direction, landfill gas management, gas collection systems, effluent management parameters, control of traffic noise, levels of odors, and the impact on the greenhouse effect.

This research indicates that the HSE conditions at the Mashhad landfill are suboptimal. Environmental and safety indicators, in particular, have been largely overlooked in landfill management practices. Establishing a dedicated HSE system within the waste management framework of Mashhad's municipal administration could significantly enhance these indicators. 

Covid-19 is a viral disease of the respiratory system. Considering that the persistence of antibodies against COVID-19 has been different in the reports and since ethnic and racial differences have been effective in this status, the purpose of this study was to examine the status of antibodies and persistence in patients with COVID-19.

This longitudinal study was conducted in 2019 on patients referred to a fever clinic in Miandorod City. The diagnosis of the disease was based on the history and real-time PCR test or lung CT scan. 87 patients were included in the study based on the diagnostic criteria, and the exclusion criteria included cases of non-return in the follow-up. The level of IgM and IgG antibodies was measured by ELISA method and Pishtaz Teb kit at the beginning of the diagnosis, and to check the stability, the IgG level of the same patients was rechecked 6 months later, and according to the instructions of the kit, values higher than 1.1 were considered positive. Data including background information, lung involvement in CT scan, and ELISA results were analyzed after entering the computer with SPSS 21 statistical software and T-test and Fisher's exact tests. P<0.05 was considered a significance level.

The mean age of the patients was 47.7±17 years. 55 people (63%) were women, 20 people (23%) had high blood pressure and 18 people (20.7%) had diabetes. 84 patients had positive real-time PCR tests, and 43 patients (49.4%) had CT lung involvement. Initial IgM was positive in 20 people (23%), initial IgG was positive in 58 people (66.7%), and after six months IgG was positive in 36 cases (41.4%). Antibody was stable in 67.4% of men and 56.4% of women (P=0.41). High blood pressure (P=0.329) diabetes (P=0.21) and lung involvement in CT scan (P=0.586) had no significant relationship with antibody stability. The average age of people with stable antibodies (50 ± 16.2 years) and those whose antibody was negative (42±14.1 years) had no significant difference (P=0.077).

The findings showed that the antibody against the disease was not produced in one-third of the patients and after 6 months, the amount of IgG had decreased in a significant part of the patients. Also, the results showed that antibody stability had no significant relationship with age, gender, lung involvement in CT scans, and underlying diseases such as hypertension and diabetes.

The relationship of safety climate and mental workload with stress, anxiety, and depression is one of the performance indicators of occupational health and safety management in the workplace, which evaluates the attitude of employees towards safety issues. The purpose of this study is to investigate the relationship between safety climate and mental workload with stress, anxiety, and depression in ABFA Company personnel in Isfahan Province, Iran.

This is a descriptive-analytical and cross-sectional study. The statistical population included 254 employees of the water and sewage incidents team in six regions of Isfahan City and the water and sewage crisis team and the relevant supervisors. The data collection tools in this research were the standard Depression, Stress, and Anxiety Scale (DASS-21), the standard NASA Task Load Index (NASA-TLX), and the standard Nordic Occupational Safety Climate Questionnaire (NOSACQ).

The increase in depression, anxiety, and stress was associated with the increase in mental workload in the target group (P < 0.05). Besides, the calculated beta coefficients were negative, which indicates an increase in depression, anxiety, and stress with a decrease in safety atmosphere in the target group personnel (P < 0.05)

The crisis team has a significant mental load in today's work environment because the tasks they perform require extreme caution and attention and must be free of any mistakes. Therefore, efforts should be made to reduce their mental load so that they can perform better. Increased depression may significantly affect people's physical and mental health and reduce their performance, commitment, quality of life, and satisfaction. Hence, the components of mental loads should be controlled and relevant measures should be taken to reduce the workload.

Traffic accidents are one of the leading causes of death in pregnant women. One of the investment areas for maternal and neonatal health is targeted interventions to increase maternal safety to prevent traffic accidents. Therefore, this study was conducted with the aim of identifying and categorizing different types of safety interventions to reduce traffic accidents in pregnant women.

The study was a systematic review. Interventional articles from Persian databases including Magiran, Iran Medex, and SID, and English scientific information databases including PubMed, Cochrane, Sciencedirect, Embase, Science of Web, and Scopus were searched. All identified articles were collected by one person using Endnote software. Then, the full text of the articles was reviewed by two researchers and the articles that met the entry criteria were identified. Other articles were added to the previous collection of articles using forward citation and backward citation reviews. The EPHPP tool was used to assess the quality of the studies.

The initial search resulted in finding 5329 article abstracts. Eventually, two interventional studies were identified for evaluation in this study. The intervention approach used in one study was educational/behavioral and in the other was engineering/technology. Both studies reported that they had made significant changes in the desired outcomes, which was fastening the seat belt in pregnant women. One study was of poor quality in quality assessment and the other was of medium quality.

Safety interventions to reduce traffic accidents in pregnant women have been very little worked on worldwide. It seems that there is still much room for studies in the field of safety interventions to reduce traffic accidents among pregnant women.

Considering the high number of traffic accidents in Iran, it seems necessary to investigate the factors related to the severity of traffic accidents. The purpose of this study was to investigate the relationship between compliance with safety precautions and the severity of injuries caused by traffic accidents in Urmia, Iran.

This was a cross-sectional study. The study was conducted retrospectively on available data of the trauma registration system from 2017 to 2022. The research population included 428 drivers who were admitted to a teaching hospital for trauma caused by the traffic accident in Urmia, Iran. Chi-square and Fisher's statistics were used to investigate the relationship between demographic variables, damaged area, behavioral factors, use of safety equipment (air bag and seat belt) and severity of injury.

From 428 drivers injured in traffic accidents, the most injuries were in the head and neck areas. Non-use of seat belts and absence of airbags were reported in 277 and 340 cases of accidents, respectively. 287 people had a history of alcohol consumption, 284 people had a history substance abuse, and 346 people had a history of drug use. A significant relationship was observed between age, gender, injured area, use of seat belts, having airbags, alcohol and drug consumption with injury severity (P<0.05). While the relationship between substance abuse and injury severity was not significant (P=0.517).

The results showed that age, gender, lack of seat belt use, lack of airbags, drug use, alcohol, and the injured area were the most factors related to the occurrence of higher severity injuries.

Constant control of electrical panels is effective in ensuring the safety of users. This study was conducted during the years 2022-2023 to evaluate their structure in blood transfusion centers by ETBA method.

In this descriptive-analytical study with the ETBA method, the performance and quality of the grounding system, capacitor bank, connections, the location of the panels, the arrangement structure of the components, and their cleanliness and safety in the centers of Kermanshah, Hamadan, Ilam, Sanandaj, Arak, Karaj, Semnan, Bandar Abbas, Sari and Yazd were investigated. The obtained information was analyzed statistically with SPSS 25 software.

The results showed 74.3% electrical panels with unprincipled volume and distribution of connections, 72.4% due to the selection of inappropriate location and distance from tools and devices, deployment in users' traffic area without provision of fence and safety devices, 70.5% not equipped with warning devices, 43.3% non-standard arrangement, 51.4% insufficient cleaning, 66.3% not having an active earth connection, and 60.3% not having a capacitor bank did not have reliable electrical safety.

Based on these results, the regular and continuous establishment and implementation of the medical equipment maintenance management system can be a fundamental and effective factor in identifying risks and the pertinent degree of risks and damages in the process of activity.

Scientific journals and research papers are considered one of the most important tools for the development and advancement of science. They are also among the most significant means of disseminating and expanding knowledge and science in today's world. Scientific and specialized journals serve as a medium for distributing, accumulating, and producing scientific data and information in every scientific field. The Iran Occupational Health Journal is the first specialized journal in the field of occupational health and safety. Therefore, analyzing the performance of this journal through scientometric methods will provide a comprehensive picture of the individuals, institutions, and topics discussed in the journal. Hence, the objective of this study is to examine the performance of this journal in the Scopus database during the years 2011 to 2022.

The present study was conducted using a descriptive-analytical approach with a scientometric perspective. The population of this research included all articles from the Iran Occupational Health Journal in the Scopus database database from the beginning of indexing in this database (2011) until the end of 2022. VOSviewer software (Version 1.6.20) and the scientometric package in R software (version 4.1.0) were used to create scientific maps. Additionally, Excel-2016 software was utilized to measure descriptive aspects of the study.

The results of the study indicate a total of 683 articles from the Iranian Occupational Health Journal that have been indexed in the Scopus citation database from 2011 to 2022. The publication trend of scientific outputs in this journal showed an increasing trend until 2017, followed by a decrease in the years 2018 and 2019. Among the participating organizations, Tehran University of Medical Sciences with a frequency of 329 articles, Iran University of Medical Sciences with a frequency of 251 articles, and Shahid Beheshti University of Medical Sciences with a frequency of 240 articles ranked as the top three active universities in producing articles for this journal respectively. The most frequent keywords were Safety, Job stress, Risk assessment, and Musculoskeletal disorders. Approximately 1.69% (472 articles) of the articles have been cited at least once by other articles, while 9.30% (211 articles) remain uncited. The average citation per article was 86.2, and the average citations per article per year was 4.0. 

In summarizing the results obtained from the performance of the Iran Occupational Health Journal, it is evident that the number of citations received by articles reflects the quality and acceptance of the papers by the scientific community. Therefore, the scientific outputs of this journal require more attention in this regard. It is recommended to take measures that will contribute to the long-term improvement of the journal's quality including sharing articles on social media platforms, involving editorial boards with diverse scientific backgrounds (e.g., utilizing the expertise of information science and knowledge management professors), attracting articles produced through increased collaboration among domestic and international researchers, and publishing more review articles alongside research papers to improve the scientometric indicators, increase visibility, and enhance the likelihood of receiving citations for the journal's articles.

Type 2 diabetes is one of the most common chronic diseases that is associated with insulin resistance and increased blood sugar levels, and affects the morbidity, mortality, and quality of life of the patients. This study was conducted with the aim of investigating the safety and effectiveness of sitagliptin and metformin combined treatment compared to metformin treatment alone in patients with type 2 diabetes.

A systematic search was conducted in PubMed, Cochrane Library, Embase, Scopus, and Web of Science databases until November 2020. The Cochrane tool was used to assess the quality of the studies. Meta-analysis was performed using RevMan software version 5.3.

Nine studies were included with a total number of 5675 patients. The results showed that in except of the comparision of the dose of 1000 mg with 100/1000 mg, there was significant differences between the two treatment groups in respect of HbA1c level. FPG was significant only at a dose of 1000 mg versus 50/1000 mg (P = 0.0001). Significant differences in the outcome of HOMA-B were observed in the studied doses. However, no significant difference was observed between the two treatment groups in the outcomes of HOMA-IR and Fasting proinsulin. Proinsulin/insulin ratio was significant only at a dose of 1000 mg versus 50/1000 mg (P <0000.1). The outcome of one or more side effects was higher at doses of 500 mg versus 50.500 (P = 0.20) and 1000 mg versus 1000/100 in the combination group (P= 0.02).

Sitagliptin and metformin combination therapy showed better efficacy than metformin treatment alone in patients with type 2 diabetes. No significant adverse events were observed for combination therapy.
