The individual’s perception of health, when health is understood to include many dimensions of life, is considered the basis for any improvement in health status. Therefore, the present study aimed to assess the reliability and validity of the Persian version of the Perceived Wellness Scale (PWS) by applying it to employees of the Shiraz University of Medical Sciences. This cross-sectional study was conducted with 180 staff members of the university selected by convenience sampling. The study instrument was a Persian version of the PWS prepared through a translation and back-translation process. The reliability and validity of the instrument were assessed by using confirmatory factor analysis (CFA) and Cronbach’s alpha coefficient. A total of 180 employees participated in the study. The mean age of the participants was 32.29 years (SD = 7.39) and 78.1% of the participants were women. The results showed that the Persian version of the PWS is acceptable. Cronbach’s alpha coefficient was 0.87 for the whole scale, ranging from 0.68 to 0.85 on different dimensions of the scale. The results of split-half reliability and CFA indicated that the reliability and validity of the PWS are acceptable. The PWS is therefore an effective tool for evaluating the different dimensions of perceived wellness in the Iranian population.

OBJECTIVES: This study was performed to evaluate the effect of blood contamination on the compressive strength (CS) of Root MTA (RMTA) modified with Calcium chloride (CaCl2) and Disodium hydrogen phosphate (Na2HPO4) as setting accelerators over time. MATERIALS AND METHODS: A total of 110 cylindrical specimens of RMTA were divided into 6 experimental groups as follows: Group1, RMTA; Group 2, RMTA modified with CaCl2 (RMTA-C); Group 3, RMTA modified with Na2HPO4 (RMTA-N); Group 4, RMTA contaminated with blood; Group 5, RMTA-C contaminated with blood; Group 6, RMTA-N contaminated with blood. The CS of specimens in all groups was evaluated after 3 hr, 24 hr, and 1 wk. In the modified groups (groups 2, 3, 5, and 6) the CS of five specimens per group was also evaluated after 1 hr. RESULTS: Blood contamination significantly reduced the CS of all materials at all time intervals (p < 0.05). After 3 hr, the CS of specimens in the RMTA groups (with and without blood contamination) was significantly lower than those in the RMTA-C and RMTA-N groups (p < 0.05). The CS values were not significantly different at the other time intervals. In all groups, the CS of specimens significantly increased over time (p < 0.05). CONCLUSIONS: Blood contamination decreased the CS of both original and accelerated RMTA.

Introduction: Sleep disorder is one of the most common problems in elderly people. The present study is focused on the effectiveness of educational intervention on sleep quality and psychological well-being in the elderly people. Method: This is a Randomized educational field-controlled trial which was conducted on 90 elderlies with the sleep disorder, who have been selected using systematic random sampling from the clients of comprehensive health centers in Borazjan, Iran, 2019. The educational intervention was presented for 5 weeks by lecture, group discussions and virtual learning methods. Data were collected by the Pittsburgh Sleep Quality Index and the Ryff’s Psychological well-being scale before and 2 months after the intervention. The data were analyzed using SPSS-25 software using independent t-test, and Chi-square test. Results: The results showed significant statistical differences in sleep quality, subscales of sleep efficiency, sleeping time, and taking sleeping pills in experimental and control groups after the intervention (p≤0.005). Moreover, significant statistical difference was observed in terms of the mean scale of psychological well-being between experimental and control groups (p=0.036). Conclusion: Behavioral interventions can make various advantages for elderly people. Therefore, this study suggests providing such interventions in a wide range in comprehensive health centers, and boarding centers for the elderly.

Introduction: Balance disorder is one of the huge risk factors for falling in elderly population. Falling leads to loss of independence of their functioning and activities of daily living. Preventing falls still exists as a challenge in public health. The aim of this study was to investigate the effect of balance exercise training on balance status, and quality of life in elderly women. Methods: In the study, 60 elderly women with dizziness and history of falling over the past 6-12 months were randomized allocated into experimental and control group. Berg Balance Scale (BBS) and Romberg tests, Dizziness Handicap Inventory (DHI), Fall Efficacy Scale-International (FES-I), and Leiden-Padua (LEIPAD) questionnaires were performed before and after training period in experimental group and compared to control group. Experimental group attended Cawthorne-cooksey (CC) and strengthening the sensory-motor system training in two-hour sessions twice in a week for 8 weeks. The repeated measure (one way and two way) ANOVA, independent-samples t-test, Bayesian Model, and ROC curve were applied to analysis the data using SPSS v.25. Results: Compared with the control group, BBS test result in 97% percent of the experimental group obtained normal. Experimental group improved significantly in the mean scores (ps<0.001) of BBS, Romberg, DHI, FES-I and some dimensions of life quality in LEIPAD. Conclusion: Balance exercises training (CC & strengthening the sensory-motor system) may induce significant improvements in balance and can be used for prevention or treatment in elderly people; further research is required to assess the long-term consequences of such interventions in elderly

Introduction: Hand hygiene plays a huge role in removing hospital infections. The aim of this study was to explore the nurses’ viewpoints about the factors affecting hand hygiene compliance. Methods: In this qualitative content analysis study, the data were collected through purposive sampling and semi-structured interviews with 15 nurses. Interviews were audio-recorded and transcribed verbatim. Thematic analyses were conducted using Lundman and Graneheim’s method. Results: Six themes were identified, including the facilitator and barriers to compliance with hand hygiene on personal, interpersonal, and organizational levels. One theme was personal facilitator, with categories of facilitating the cognition and adherence to values. Personal barriers included cognitive obstacles, attitudinal barriers, and physical barriers. The interpersonal facilitators included supportive social climate and appropriate culture building. The interpersonal barriers involved inappropriate culture building and being under pressure. The organizational facilitators were strong leadership style, good managerial support, and competent staff evaluation; the last theme was organizational barriers with categories of poor leadership style, ineffective staff development, inconsistency in organizational policy, and incompetent staff evaluation. Conclusion: This study adopted an integrated approach to examining the factors affecting the nurses’ hand hygiene compliance. It is recommended that future interventions should consider the differences at individual, interpersonal, and organizational levels and developed a tailoring approach.
