Background & aim: Lifestyle diseases kill 41 million people yearly, equivalent to 71% of all deaths globally. Studies have shown that increasing level of inappropriate nutrition, substance abuse, physical inactivity and stress in lifestyles underlies these diseases; This study aimed to identify the effective factors on increasing level of risk factors and unhealthily of Iranian lifestyles and then to provide a strategic model to prevent their occurrence and prevalence.
Methods: The research method was qualitative grounded theory which conducted with participation of 14 experts from different disciplines who were purposefully selected. The data were collected based on theoretical sampling by in-depth interview and were analyzed by continuous comparison method and theoretical coding in strauss and corbin's systematic paradigm (1998). Its validity and reliability were obtained by referring the findings to data and the results to specialists.
Results: Socio-pathology of Iranian lifestyles from the experts' point of view provided 216 concepts and 37 sub-categories, and finally the following 10 main categories, explaining the weaknesses of society in establishing healthy lifestyles were obtained: Education, Upbringing, Propagation, Financing, Facilitation, Prescription, Gathering, Obedience, and Assurance dimensions. The "unhealthily of lifestyles" was selected as the central phenomenon and ten categories were related to it in two groups of contextual and interferer conditions, and finally decuple strategic model was presented.
Conclusion: Prevention of lifestyle diseases requires attention to structural and individual aspects of lifestyle. The first seven strategies focused in the macrolevel on social structures, the eighth strategy in the Intermediate level on family, and the ninth strategy in the microlevel on human factors. The tenth strategy represents a research proposal to establish an organization between structure and agency to measure and monitor the health status of Iranian lifestyles toward healthy lifestyle.

Background & aim: The first step in improving patient safety in hospitals is to evaluate the safety culture in medical units. Nurses can help promote a patient safety culture through a sense of responsibility and professional commitment. The purpose of this study was to determine the relationship between nurses' professional commitment and patient safety culture in teaching hospitals of Shahrekord University of Medical Sciences.
Methods: This descriptive correlational study was performed in three hospitals of Shahrekord and Borujen. The sample consisted of 359 nurses who were selected based on multistage sampling. Data collection tools were demographic information form and hospital survey questionnaires about patient safety culture and professional commitment of nurses. Data were analyzed by SPSS-20 software using descriptive statistics (mean and standard deviation) and liner regression.
Results: The mean scores of patient safety culture and professional commitment of nurses were 123.23 ± 16.15 and 85.65 ± 15.04, respectively. The results of regression test showed that there was a significant relationship between different dimensions of professional commitment and patient safety culture (p<0.001).
Conclusion: Based on the findings of the study, nurses with a high level of professional commitment have a higher safety culture. Therefore, an effort to improve the level of professional commitment of nurses can promote a patient safety culture. Authorities can also improve the quality of service and patient safety through dedicated empowerment.

Background & aim: Nowadays, the prevalence of chronic low back pain is increasing in the world and vitamin D deficiency is associated with impaired neuromuscular function and chronic musculoskeletal pain. In addition, exercise therapy and selection of core stabilization exercise interventions have main roles in rehabilitation of these patients. The aim of this study was to investigate the effect of 8 weeks of core stabilization exercises and vitamin D intake on the pain and functional disability levels in women with chronic non-specific low back pain.
Methods: This clinical trial study was performed by pre-test and post-test design. Initially, 48 women with chronic non-specific low back pain were selected by available sampling method and then randomly divided into control, exercise, vitamin D and exercise+vitamin D (combined) groups (12 subjects in each group). The exercise and combined groups performed 8 weeks of core stabilizing exercises. The vitamin D and combined groups received 50,000 IU vitamin D/week for 8 weeks. The severity of the pain and functional disability, before and after the interventions, were determined by visual analog scale of pain and Oswestry questionnaire, respectively. Data analysis was performed using Paired T-Test and ANOVA with the significance level of less than 0.05.
Results: Eight weeks of core stabilizing exercises, vitamin D intake and the combined intervention were associated with a significant reduction (p<0.001) in pain (20.15%, 18.60% and 34.20%, respectively) and functional disability (48.35%, 44.26% and 51.81%, respectively) in women with chronic non-specific low back pain. In addition, combined intervention induced more reduction in the pain compared with two other interventions (p<0.001)
Conclusion: It seems that core stabilizing exercises, vitamin D intake, and the combination intervention can reduce the pain and improve the physical function in patients with chronic low back who have low levels of vitamin D. But combined intervention is associated with greater effectiveness in reducing the pain.

Background & aim: Concerns about career prospects are a topic that has recently increased in various disciplines. The aim of this study was to determine the attitude of operating room students of Hamadan university of medical sciences toward their discipline and future career during the corona virus epidemic
Methods: In this descriptive-analytical study, 170 operating room students of Hamadan university were selected by stratified sampling method. The research tool was students' attitudes toward the field of study and career prospects questionnaire which were completed as electronically and in writing. Data were analyzed using SPSS software and one-way ANOVA and independent t-test.
Results: The mean scores of student attitudes toward the field of study and career future were 29.00±5.63 and 19.62±3.30, respectively. 67.1% of students had a favorable view of their field of study and 67.6% had a favorable view of their future career. Also, there were statistically significant relationships between the year of entering the university with their attitude towards the field of study (p=0.001) and career future (p=0.003), and the accommodation of students with attitude towards career future (p=0.010).
Conclusion: The attitude of the majority of operating room students of Hamadan university of medical sciences towards their field of study and future career was favorable at the time of the corona virus epidemic. A more complete acquaintance of people with the field of study before choosing a field, increasing the job capacity of working in the operating room and adjusting the admission capacity of students can play a significant role in strengthening these types of attitudes.
