Introduction: Due to the high consumption of dietary supplements and the need to identify the factors affecting consumption to design effective interventions, the aim of the present review is to the factors affecting the consumption of supplements in studies conducted on healthy adults between 1996 and 2020. Materials and Methods: The present study was conducted by reviewing 584 articles from the last 24 years and searching the databases of Scopus, PubMed, Science Direct Springer, Cochrane, Embase, Medlib, Magiran, SID, and the Google Scholar search engine. Based on the PRISMA guide, 54 articles were selected and reviewed. Results: Most cross-sectional and cohort studies have shown the effect of gender, education, and age on dietary supplement consumption. The only trial study showed the effect of gender and only a review study showed the effect of gender, age, education, and income. Women take supplements more than men. With increasing education, age, physical activity, body mass, and income dietary supplements consumption increases. Other factors such as smoking, race and ethnicity, chronic diseases, alcohol consumption, living in a metropolitan, marriage, lifestyle, perceived health, and higher health awareness, drug use, and self-efficacy have also affected consumption. Conclusion: The studies have been limited to examining the relationship between demographic factors and use and less attention has been paid to factors such as awareness and beliefs about supplement use. Therefore, in order to achieve more definitive results and increase the efficiency of interventions designed in the field of consumption of these supplements, it seems necessary to conduct prospective and intervention studies.

Introduction: Recently, the study of the impact of art on human performance has attracted many researchers. Also, art can improve academic performance and personal growth of medical graduates. At the same time, little attention has been paid to the role of art in medical education. The purpose of this study was to investigate the use of art in medical education from the viewpoint of Birjand University of Medical Sciences students and to analyze the students' practical approach to using art and their different attitudes about the successful and effective impact of art on education. Materials and Methods: The descriptive-analytical research was performed on Birjand University of Medical Sciences students in 2018-2019. Valid and reliable questionnaires were made available to students electronically (mobile application). Results: 101 students including 38 male students and 63 female students were included in the study. The results showed that 27% of students were pursuing a particular artistic discipline. Over 80% of students were engaged in an artistic activity while studying, in this issue, music was introduced as the most effective art. The students also agreed to the integration of art in the curriculum and its infrastructure development. Conclusion: taking advantage of the arts to learn is part of the students' daily schedule, yet no formal action has been taken. On the other hand, medical humanities as the basis of the art integration in medical education require a serious introduction and practical attention.

Introduction Bee venom (BV) contains compounds that have biological and biochemical activitis. Therefore, purification of BV and investigation of its biochemical properties can be useful in understanding its therapeutic aspects. In the present study, the biochemical effects of Apis mellifera venom on the blood and liver of laboratory mice were investigated. Materials and Methods Protein concentration of Apis mellifera crude venom was determined. Purification of venom was performed with Sephadex G-50 chromatography. SDS-PAGE was used to determine the protein profile of BV and its fractions. The hemolytic activity of venom was investigated. Biochemical tests were performed in one control group (with a normal diet and without injection of venom) and three experimental groups (with injections of different venom doses). Results Crude venom protein concentration was about 4. 1 mg/ml. The chromatogram showed three large peaks and melittin account for about 50% of the BV. By electrophoresis, it was found that the venom has compounds with a molecular weight of 3 to 90 kD, including melittin, phospholipase, hyaluronidase, acid phosphomonoesterase. The hemolytic test showed HD50 of melittin at a concentration of 0. 5 μ g/ml. Biochemical tests on the control and the three experimental groups showed that when venom dose increased in the three experimental groups; the group with the highest venom dose (0. 1 mg/ml) showed the highest decrease in serum parameters compared to the control group. Conclusion BV, especially melittin, has a significant hemolytic activity and biologically very active, so it can be used to treat some diseases.

Introduction: The National Health Information Network (NHIN) is a network through which all healthcare providers exchange health information. Since the architecture of such a network is one of the most important factors involved in the design of NHIN; this study aimed to explore the experiences of leading countries in the development of NHIN architecture and providing solutions to developing countries. Materials and Methods: In this descriptive-comparative study, the nationwide health information networks of the United States and the United Kingdom were reviewed. A researcher-made checklist was used to collect information. Then, according to the aspects of NHIN architecture, the NHIN documents of the countries under study were analyzed and the findings were presented in comparative tables. Results: The NHIN architecture in the US, which involves connecting regional health information networks, had a bottom-up approach. The network N3 of the National Health Information Technology Program of the UK with a centralized structure had a top-down approach. Conclusion: Each of the approaches used in the NHIN architecture in the studied countries has advantages and disadvantages. Developing countries should use one of these approaches or a combination of them to design the NHIN architecture, given the centralization or decentralization of their health systems.

Introduction: Staphylococcus aureus (S. aureus) has been recognized as a powerful pathogen that causes numerous infections. Today, S. aureus has acquired multiple resistance to a wide range of antibiotics, including beta-lactams. Betalactamases hydrolyze beta-lactam antibiotics and are expressed through activation of the blaZ gene. The aim of this study was to evaluate the frequency of blaZ gene in clinical isolates of S. aureus isolated from Hamadan hospitals. Materials and Methods: In this descriptive cross-sectional study, all S. aureus strains were randomly selected and transferred to the laboratory. In clinical isolates confirmed by biochemical tests of genomic DNA extraction procedures using CinnaGen extraction kit) was performed according to the manufacturer's protocol and 1% agarose gel was used to view the PCR product. Data were analyzed by SPSS software. Results: From 50 hospitalized patients in Fatemieh and Sina hospitals, 32 men (64%), and 18 women (36%), isolates of S. aureus were isolated. The pattern of antibiotic resistance obtained was that penicillin (10 μ g) with 100% resistance and cefazolin (30 μ g) with 5% resistance had the highest and lowest resistance, respectively. Also, 94% of isolates were resistant to cefoxitin (30 μ g) and 90% of isolates were resistant to oxacillin (1 μ g). Of 50 S. aureus isolated from clinical isolates, 44 (88 %) contained the blaZ beta-lactamase gene. Conclusion: Based on the findings of this study, isolates isolated from clinical specimens showed the same pattern of abundance. Therefore, it is likely that more or more drug resistance will be transmitted to hospitals.

The aim of this study was to investigate the effect of combined training on level of immune factors in HIV-infected patients. Materials and Methods: In this semi-experimental study, 30 male patients with AIDS were targeted and accessible selected and randomly divided into two groups; combined training and control. The combined training program was run for 12 weeks and 3 sessions per week. Aerobic training involves walking or jogging on the treadmill with rising intensity and duration of 40% to 65% of maximum heart rate and a duration of 30-60 minutes. Also, Strength training includes 2 to 4 sets and 12 to 20 repetitions per isotonic device in the range of 40% to 60% 1RM. 24 hours before and 72 hours after intervention, blood samples were retested. CD4 lymphocytes and Viral Load levels measured by flow cytometry. Data were analyzed by independent t-test at the P <0. 05. Results: The results showed that 12 weeks of the combined exercise was associated with a nonsignificant increase in CD4 levels in patients with acquired immunodeficiency (AIDS) (p=0. 461). Combined exercise had no significant effect on serum viral load in patients with acquired immunodeficiency (AIDS) (p=0. 926). Conclusion: According to the results of the study, there was a slight increase in CD4 count in the exercise group but this value was not significant. However, it was clinically valuable. Therefore, combined training can be performed safely and effectively in these patients.

Introduction: Several factors are involved in causing the brain death chain. Understanding these factors can help us understand the cause of this chain and prevent it From the perspective of the patients’ families with brain death. Therefore, this study aims to explain the family members' experiences of patients with brain death regarding the cause of brain death chain as a qualitative study. Materials and Methods: This qualitative research was conducted as a content analysis. Fourteen firstdegree family members of patients with brain death were interviewed using in-depth semi-structured interviews to the point of data saturation. Purposive sampling was conducted on the families of patients with brain death admitted to the intensive care unit of Ayatollah Mousavi Hospital in Zanjan. The conventional content analysis method was used to analyze the data. Results: In data analysis, the main theme is “ brain death chain" and " brain death due to head trauma", "poor pre-hospital measures", "heavy bleeding in an accident", "patient to blame in the accidents "and "brain death due to family disputes" were sub-themes. Conclusion: Identifying the main causes of brain death chain is very important from the perspective of patients' families. Because it can create a good mental background for medical staff, especially nurses when coping with such a situation. Understanding the condition of the patient and their families and identifying the factors causing the brain death chain by the health care staff can lead to quick and appropriate care to reduce the damage.
