Background: Despite the advantages of dual peer mentoring, there are a few reports of implementing and evaluating such programs for medical students. This study aimed at exploring the perceptions of mentors and mentees about the dual peer mentoring program for the first year undergraduate medical students of Tehran University of Medical Sciences. Methods: This qualitative study was conducted at the end of the first year of implementing the mentoring program. All mentees and mentors were invited to participate in focus group discussions. Data were analyzed using a qualitative content analysis. Results: All mentors (n= 12) and a group of mentees (n= 21) participated in focus group discussion sessions. We provided a variety of supports for the mentees including academic and psychosocial support and positive relationship; as a result, some developments occurred to the mentors We also explored participants’ views on some unique aspects of the program such as student-authorized, dual mentoring, and role model sessions. Conclusion: Our participants found the mentoring program beneficial in various academic achievements and psychosocial supports for both the mentors and the mentees. Dual peer mentoring program can be an alternative to school administered programs.

This study aimed to evaluate the quality of the educational environment in Tehran University of Medical Sciences across different medical specialties and its correlation with residents' burnout. Materials and methods: This cross-sectional study was conducted at Tehran University of Medical Sciences among residents drawn from three largest teaching hospitals affiliated. The Maslach Burnout Inventory and Postgraduate Hospital Educational Environment Measure (PHEEM) questionnaire were used to collect data through web-based, as well as paper-and pencil questionnaires. The data was analyzed using SPSS. Results: A total of 221 residents completed the survey, with a response rate of 82%. Burnout was reported by 67.4% of medical residents. The total PHEEM score had a negative correlation with emotional exhaustion (r ¼ -0.57, P < 0.001), depersonalization (r ¼ -0.40, P < 0.001), and a positive one with personal accomplishment (r ¼ 0.42, P < 0.001). Perception of social support significantly predicted burnout subscales (P < 0.05). PHEEM subscales also explained a small proportion of variance in emotional exhaustion (R ¼ 0.55, R 2 ¼ 0.308, P < .001). Clinical learning environment independent of personal characteristics was associated with residents' burnout according to multivariate regression analysis [OR ¼ 0.567 (0.170-0.883), P ¼ 0.012]. Conclusion: Clinical learning environment independent of personal characteristics was associated with residents' burnout in Iran. We suggest some initiatives to be introduced ranging from improving the clinical environments, reduce workloads and provide social support to all residents as well as encouraging them to involve in other extracurricular activities like music and physical exercise.

Objective This study aimed to review and summarize the existing evidence on the effectiveness of vibration therapy (VT) in comparison with conventional rehabilitation in anterior cruciate ligament (ACL)-reconstructed patients considering muscle peak torque and postural control. Methods We searched available online databases for relevant studies published up to February 2020. All randomized clinical trials investigating the effect of VT on quadriceps peak torque, hamstring peak torque, and postural control (closed-eye and open-eye) were included. Overall, 13 clinical trials with a total sample size of 407 participants were included for the meta-analysis. We used the pooled mean difference with random effects model for meta-analyses. We assessed the heterogeneity of the studies using the I2 and Cochran’s Q test. Meta-regression analysis was used to assess the source of heterogeneity. Results We found that VT significantly improved hamstring peak torque [weighted mean difference (WMD) 12.67, 95% CI 4.51–20.83] and quadriceps peak torque (WMD 0.11, 95% CI −0.06 to 0.29). However, subgroup analysis showed a significant increase in mentioned muscles’ peak torque in studies employing interventions including both local muscle vibration (LMV) and vibration frequency higher than 100 Hz (WMD 20.84, 95% CI 11.75–29.93). With regard to postural control, we observed a significant improvement only in open-eye mediolateral postural control (WMD 0.26, 95% CI −1.26 to 1.77). Conclusion This study suggests that VT, especially LMV type with vibration frequency higher than 100 Hz, can be effective in rehabilitation of ACL-reconstructed patients. Although improvement in the peak torque of hamstring and quadriceps muscles was seen, there was no significant improvement in postural control, especially closed-eye, in comparison with conventional rehabilitation. Level of evidence 1. Highlights Vibration therapy can increase hamstring peak torque in individuals with ACL reconstruction. Local muscle vibration type in comparison with whole-body vibration is recommended for ACL-reconstructed patients. Vibration frequency higher than 100 Hz is preferred in ACL-reconstructed rehabilitation.
