Blue Light and Digital Screens Revisited: A New Look at Blue Light from the Vision Quality, Circadian Rhythm and Cognitive Functions Perspective.

Research conducted over the years has established that artificial light at night (ALAN), particularly short wavelengths in the blue region (~400-500 nm), can disrupt the circadian rhythm, cause sleep disturbances, and lead to metabolic dysregulation. With the increasing number of people spending considerable amounts of time at home or work staring at digital screens such as smartphones, tablets, and laptops, the negative impacts of blue light are becoming more apparent. While blue wavelengths during the day can enhance attention and reaction times, they are disruptive at night and are associated with a wide range of health problems such as poor sleep quality, mental health problems, and increased risk of some cancers. The growing global concern over the detrimental effects of ALAN on human health is supported by epidemiological and experimental studies, which suggest that exposure to ALAN is associated with disorders like type 2 diabetes, obesity, and increased risk of breast and prostate cancer. Moreover, several studies have reported a connection between ALAN, night-shift work, reduced cognitive performance, and a higher likelihood of human errors. The purpose of this paper is to review the biological impacts of blue light exposure on human cognitive functions and vision quality. Additionally, studies indicating a potential link between exposure to blue light from digital screens and increased risk of breast cancer are also reviewed. However, more research is needed to fully comprehend the relationship between blue light exposure and adverse health effects, such as the risk of breast cancer.

Designing a model of emergency medical services preparedness in response to mass casualty incidents: a mixed-method study.

BACKGROUND: Emergency medical services preparedness in mass casualty incidents is one of the most important concerns in emergency systems. A mass casualty incident is a sudden event with several injured individuals that overwhelms the local health care system. This study aimed to identify and validate the components of emergency medical services readiness in mass casualty incidents which ultimately led to designing a conceptual model. METHODS: This research was an explanatory mixed-method study conducted in five consecutive stages in Iran between November 2021 and September 2023. First, a systematic review was carried out to extract the components of emergency medical services preparedness in mass casualty incidents based on the PRISMA guideline. Second, a qualitative study was designed to explore the preparedness components through in-depth semi-structured interviews and analyzed using the content analysis approach. Third, the integration of the components extracted from the two stages of the systematic review and qualitative study was done by an expert panel. Fourth, the obtained components were validated using the Delphi technique. Two rounds were done in the Delphi phase. Finally, the conceptual model of emergency medical services preparedness in mass casualty incidents was designed by a panel of experts. RESULTS: 10 articles were included in the systematic review stage and sixteen main components were extracted and classified into four categories. In the second stage, thirteen components were extracted from the qualitative study and classified into five categories. Then, the components of the previous two phases were integrated into the panel of experts and 23 components were identified. After validation with the Delphi technique, 22 components were extracted. Lastly, the final components were examined by the panel of experts, and the conceptual schematic of the model was drawn. CONCLUSIONS: It is necessary to have an integrated framework and model of emergency medical service readiness in the planning and management of mass casualty incidents. The components and the final model of this research were obtained after the systematic scientific steps, which can be used as a scheme to improve emergency medical service preparedness in response to mass casualty incidents.

Identification of Factors Influencing Professional Identity Development in Medical Students at Basic Sciences Stage.

Introduction: Medical education is beyond gaining a certain level of knowledge and mastering a specific set of skill. Medical students should try to improve the self and system, which necessitates personal growth and professional identity development. In this study, we aimed to investigate the factors which contribute to the formation of professional identity of medical students in basic sciences stage and finding out the significance of each factor. Methods: In this cross-sectional practical survey, semi-structured interviews were done with 10 medical students. The interview results yielded several items, which were used to make a 14-item questionnaire, the validity and reliability of which were verified. The contribution of the items to the factors was verified through factor analysis, the prerequisites of which were KMO and Bartlett test, which were done and approved. The significance of the factors obtained was evaluated and ranked through one sample t-test and Friedman test, respectively. Results: The result showed that professional identity development in the stage of basic sciences was influenced by several factors, including educational, socioeconomic, personal, and familial ones. Also, the personal factor ranked first, followed by socioeconomic, educational, and familial factors, respectively. Conclusion: In this study, it was concluded that the participants were more influenced by their own personal attitudes as compared to their familial, socioeconomic, or educational factors. Moreover, the factors which contributed to the professional identity of medical students were not at the same level of significance. To train physicians with high professional identity, medical education authorities are recommended to consider the above-mentioned factors.

A new practical approach using TeamSTEPPS strategies and tools: - an educational design.

BACKGROUND: Teamwork has played a critical role in ensuring patients' safety and preventing human errors in surgery. With advancements in educational technologies, including virtual reality, it is necessary to develop new teaching methods for interpersonal teamwork based on local needs assessments in countries with indigenous cultures. This study aimed to design and develop a new method of teaching teamwork in cesarean section surgery using virtual reality; we further evaluated the effects of this method on healthcare professionals' knowledge and attitudes about teamwork. METHODS: This study was designed using the ADDIE instructional design model. The TeamSTEPPS Learning Benchmarks questionnaire was used to assess the educational needs of 85 participants who were members of the cesarean section surgery team. A specialized panel analyzed the extracted needs, and the scenario was compiled during the design stage. Finally, four virtual reality contents were created using 360-video H.265 format, which were prepared from specified scenarios in the development of the educational program. The TeamSTEPPS Learning Benchmarks questionnaire was used to measure knowledge, and the T-TAQ was used to measure the participants' attitudes. RESULTS: Six micro- skills were identified as training needs, including briefing, debriefing, cross-monitoring, I'M SAFE checklist, call-out and check-back, and two-challenge rule. Intervention results showed that the virtual reality content improved teamwork competencies in an interprofessional team performing cesarean section surgery. A significant increase was observed in the mean score of knowledge and attitude after the intervention. CONCLUSION: Through addressing the need for teamwork training, utilizing the TeamSTEPPS strategy, and incorporating new educational technologies like virtual reality, the collaboration among surgical team members can be enhanced.

Preparedness of Iranian nurses against COVID-19: An analytical study.

Background and Aims: The reasons for the unfavorable performance of hospitals in providing care to Coronavirus Disease 2019 (COVID-19) patients include the lack of preparation, knowledge, and relevant skills, making it necessary to evaluate the preparedness of nurses to respond to COVID-19. Therefore, the present study aimed to investigate the preparedness of hospitals affiliated with Shahrekord University of Medical Sciences during the COVID-19 pandemic in 2022. Methods: In this analytical study, data were collected from 350 randomly selected nurses who worked in three hospitals affiliated with Shahrekord University of Medical Sciences; demographic information tools and the preparation of nurses for COVID-19 patients were used to collect the data. We analyzed the data using SPSS software version 26. Results: The mean and standard deviation of the total preparation score was 118.85 ± 0.98. The lowest (6.80 ± 0.18) and highest (23.35 ± 0.19) average values belonged to risk assessment and management and COVID-19, respectively. The score of nurses' preparedness to deal with COVID-19 was not statistically correlated with age, work experience, and so on. The average preparation score was significantly different in different treatment departments (operating room and COVID-19). Conclusion: The preparation of nurses was low in dealing with COVID-19. Thus, managers of nursing services should design and implement educational programs to strengthen the nurses' weaknesses and ultimately increase their awareness and skills in dealing with disasters.

The effect of Crocus sativus L. (saffron) herbal tea on happiness in postmenopausal women: a randomized controlled trial.

BACKGROUND: Evidence suggests that menopause can be associated with a variety of negative psychological changes such as depression and anxiety, and improving the mental health status of women during menopause is one of the important priorities and challenges of the health system. The aim of this study was to determine the effect of saffron (Crocus sativus L., Iridaceae) herbal tea on happiness in postmenopausal women. METHODS: In this randomized clinical trial which was conducted in 2021, 72 postmenopausal women were enrolled and divided into intervention and control groups. The randomization blocks method was used for random allocation, and the Oxford Happiness Questionnaire was utilized to measure the scores. The intervention included the use of 30 mg of dried stigmas of the saffron plant, which was boiled once (in the morning, in 300 ml of boiling water for 10-15 min) and consumed with white rock candy as one cup of saffron tea daily. To compare the trend of changes and after removing the effect of other variables, generalized estimating equation (GEE) was used. RESULTS: There was no significant difference between the intervention and control groups in any of the quantitative and qualitative characteristics (p > 0.05). The results of paired samples t-test showed that the happiness mean score in the intervention group increased significantly (p < 0.001) from 42.93 ± 8.54 to 61.58 ± 8.24, while in the control group, there was no significant difference between the happiness mean score at the beginning and end of the study (p = 0.861). Also, after applying the treatment program in the intervention group, there was a significant difference between the two groups in terms of the happiness mean scores (p < 0.001). CONCLUSION: Saffron herbal tea had a positive effect on reducing depression and increasing the happiness score; thus, it is recommended that it should be used as a complementary treatment in consultation with the treating physician. TRIAL REGISTRATION: The present study was registered with the code of IRCT20210403050818N1 (Registration date: 09/04/2021) in the Iranian Registry of Clinical Trials.

The first theme was to explain competencies based on role and task with two sub-themes: Tasks and capabilities and development and excellence of personal qualities. The second theme was the best strategies for empowering the teachers with four sub-themes, including problem-based learning, integration of methods, evaluation-based education, and scholarship in education (PIES), which explains the strategies that can support the development of teachers in medical sciences universities, and all the concepts were interrelated to each other. CONCLUSION: From the experiences of faculty members, the importance of some strategies in education and empowering the teachers' professional competence dimensions should be emphasized. PIES could explain the practical strategies that can support the development of teachers in medical sciences universities.

An evaluation of the risk factors associated with implementing projects of health information technology by fuzzy combined ANP-DEMATEL.

BACKGROUND: Application of a Clinical Information System (CIS) like Electronic Patient Record (EPR), PACS system and CPOE has turned into one of the most important criteria of priorities of health care systems. The aims of the clinical information system include improving the physicians' efficiency level, integrating the caring process, and expanding the fuzzy quality of the services offered to patients. Achievement of these benefits in reality is not an easy task, and there are lots of plans in this field which are doomed to failure. About 50% of the implementation plans of clinical information systems in health care organizations have failed, and this trend is significantly affecting industrial countries. Proper implementation of hospital information systems lies in identifying and assessing the relationships among the most important risk factors of fuzzy. The present study aimed to provide an applicable model for identifying, ranking and evaluating the risk factors associated with projects of clinical information technology in hospitals of Shiraz University of Medical Sciences. METHOD: This is an applied study which evaluates the risk factors associated with implementation of clinical information technology projects in hospitals of Shiraz Medical Sciences University. The participants consisted of professionals and senior experts of clinical information technology. Fuzzy logic was used in this study. We also applied ANP-DEMATEL combined model with fuzzy procedure to provide the analytic model of the study. RESULTS: According to the study findings, lack of top-executive supports, and unstable organizational environment were the two most important risk factors, while the main organizational factors and technology were also highly important. In addition, the factors associated with technology had the highest influence on the other studied risk factors. CONCLUSION: Hospital authorities can benefit from this proposed model to reduce the risk of implementing the projects of clinical information technology and improve the success coefficient of the risk of such projects.

Descriptive and inferential statistics were used for data analysis, through SPSS. Results: The results showed that self-regulatory learning strategies in subjects with good reflectivity were significantly higher than those with poor reflectivity; also, the scores of cognitive strategies and motivational beliefs were significantly higher in the participants with good reflectivity. There was no significant relationship between reflectivity and subscales of self-regulated learning strategies and also between reflectivity and self-regulated learning strategies in the full time and virtual courses. Conclusion: It was found that there was a positive and meaningful relationship between reflectivity and self-regulated learning. Therefore, it is recommended that the managers and professors in medical universities should provide training programs in this field in order for the students to benefit from the advantages of reflectivity and self-regulated learning.

The role of continuing medical education programs in promoting iranian nurses, competency toward non-communicable diseases, a qualitative content analysis study.

BACKGROUND: Continuing medical education is essential for nurses to provide quality patient care and upgrade their professional skills and competence. The need for continuing medical education (CME) has become more apparent in the face of advances in medical science, the ever-changing healthcare system, and nurses' vital role in improving health care. It is, therefore, imperative to explore the nurses' experience of CME courses and the extent to which such programs are effective. OBJECTIVE: The present qualitative study aimed to explore and describe nurses' experiences of the effect of CE programs in promoting their competencies toward non-communicable diseases. METHODS: This qualitative content analysis study was conducted from December 2019 to April 2020 at various hospitals affiliated to Shiraz University of Medical Sciences (Shiraz, Iran) and based on the principles of conventional content analysis. The target population was nurses who actively worked in the chronic wards of these hospitals. The participants were selected using maximum variation sampling, including nine nursing managers, education and clinical supervisors, and staff nurses. Data were collected through individual, face-to-face, semi-structured interviews guided by an interview guide, and data collection continued until data saturation was achieved. Each interview took about 30-45 min. Follow up questions were used for clarification when needed. Data trustworthiness was assessed according to the criteria proposed by Guba and Lincoln. RESULTS: Analysis of the interview data resulted in 230 primary codes, based on 8 categories, and three themes were identified. The extracted themes were gaps in the planning of the CME program, problematic context, and training to improve professional skills and competency. The associated categories were gaps in the planning of the CME program, problematic context, and training to improve professional skills and competency. CONCLUSION: Professional competence and performance of nurses can be improved through intrinsic motivation stimulation, planning, and implementation of training programs based on professional needs and effective assessment of the teaching/learning process.

Healthy lifestyle during pregnancy: Uncovering the role of online health information seeking experience.

In the new era, many people seek their health-related information through the Internet due to the increasing access to this technology. Searching online health information can affect the health behavior. This study aimed to investigate the correlation between online health information-seeking behavior and a healthy lifestyle during pregnancy in a sample of Iranian pregnant women. This cross-sectional study was conducted among pregnant women admitted to health centers of Eghlid city, Fars province, Iran in 2019. A total of 193 women participated in the study. The required data were gathered using two validated questionnaires to measure the online health information-seeking behavior and the healthy lifestyle practices of the participants. The collected data were analyzed through descriptive statistics and Pearson correlation coefficient using SPSS version 22. Online health information experience and its subscales showed no statistical correlation with a healthy lifestyle. Age and education did not correlate with online health information-seeking behavior. Age had a statistical correlation with a healthy lifestyle, but education had the same correlation only with some subscales of a healthy lifestyle. The findings were surprising, suggesting that online health information-seeking behavior does not affect the lifestyle of pregnant women. These finding and probable explanations are discussed, but due to the limited literature on the subject, further studies are recommended to be conducted.

Effect of positive thinking training on stress, anxiety, depression, and quality of life among hemodialysis patients: A randomized controlled clinical trial.

BACKGROUND: Given the relationship between positivity interventions and psychological problems, this study aimed to investigate the effect of positive thinking training on stress, anxiety, depression, and quality of life of hemodialysis patients. MATERIALS AND METHODS: This is a quasi-experimental and interventional study conducted on 70 hemodialysis patients referred to Fasa hemodialysis centers, Iran, between April 2019 and October 2019. Patients were selected using a simple sampling method and randomly divided into control (n = 35) and intervention (n = 35) groups. The intervention group was trained on positive thinking skills in eight sessions of a workshop. Before and after the intervention, stress, anxiety, depression, and quality of life in both the groups were measured using the Depression, Anxiety, and Stress Scale-21 and Short Form-36 Questionnaire. Data were analyzed using paired t-test, independent t-test, Kolmogorov-Smirnov, and Chi-square tests. RESULTS: There was no significant difference in the mean scores of stress, anxiety, depression, and quality of life in the two groups before the intervention.(P > 0.05), and in the control group, there was no statistically significant difference before and after the intervention (P = 0.092, P = 0.228, 0.280, respectively). In the intervention group, the mean score of stress and anxiety decreased from 23.65 ± 4.12 to 16.68 ± 4.41 (P < 0.001) and from 17.77 ± 5.15 to 14.57 ± 4.18 (P = 0.002), respectively, and that of the patients' quality of life also increased from 35.19 ± 10.07 to 55.98 ± 11.71 (P < 0.001). However, the mean score of depression did not change significantly after the intervention (P = 0.689). CONCLUSION: According to the results of this study, the use of positive thinking intervention programs with other methods for hemodialysis patients' care and treatment is recommended as a nonpharmacological, cost-effective, and uncomplicated method.

The relationship between empowerment and job burnout in auxiliary health workers in 2019.

INTRODUCTION: Health-care workers in community service professions are the formerly candidate for occupation burnout. This study aimed to investigate the relationship between empowerment and job burnout among auxiliary health workers (behvarzan) at Fasa University of Medical Sciences. MATERIALS AND METHODS: In this descriptive-analytical study, 120 auxiliary health workers were enrolled using the census. Spritzer's psychological empowerment and Maslach burnout inventory questionnaires were used to collect the data. Then, they were analyzed through the SPSS software, using descriptive analytical tests. RESULTS: The findings of this study revealed that the auxiliary health workers' empowerment was in the range of 22-75 with a mean ± standard deviation [SD] of 48.5 ± 9.71, which is in a fairly high level considering the highest score (75) in this scale. Moreover, with respect to burnout (mean ± SD of 58.03 ± 18.64), 36 participants (30%) had low level of burnout, 69 subjects (57.5%) were at the intermediate level, and 15 (12.5%) suffered high levels of job burnout. According to the results of this study, there were a high correlation and negative relationship (r = 0.406, P > 0.001) between psychological empowerment and job burnout among the auxiliary health workers. On the other hand, all empowerment components (competence, autonomy or independence, effectiveness, and trust) had a reverse and significant association with burnout. CONCLUSION: Based on the results of this study, the auxiliary health workers (behvarzan) were in a good range of empowerment; also, the dimensions of empowerment were correlated with job burnout in Fasa university-affiliated hospitals' health workers. On the other hand, demographic features had no association with these two factors. It is suggested that health authorities should take measures to empower the workers and identify and remove the effects of the various dimensions of job burnout among the health workers in these hospitals.
