Title: Comparing students’ performance in self-directed and directed self-learning in College of Medicine, University of Bisha Authors: Salih, Karimeldin M.; Al-Faifi, Jaber; Alamri, Mohannad M.; dkk. Abstract: Background: Student-centered learning strategy increases the likelihood of graduation of competent, selfdependent, and problem-solving physicians. The University of Bisha, College of Medicine (UBCOM) adopted self-directed learning (SDL) represented by problembased learning (PBL), and directed self-learning (DSL) represented by team-based learning (TBL). Aim: To compare the students’ performance in SDL and DSL among UBCOM students. Methodology: A total of 502 multiple choice questions (MCQs) from the mid-course and final exams were collected by the relevant subject experts from nine courses during the period from September 2020 till June 2023 that adopted PBL and TBL; 247 MCQs related to PBL and 255 related to TBL. Psychometric analysis was used to determine difficult, easy, and optimum questions ( 25%, 90%, and 26e89%, respectively). Point biserial as <0.19, 0.20e0.29, 0.30e0.39, and >0.40 which indicate poor, marginal, good, and excellent point biserial, respectively. Finally, the number of functional distractors was attempted by >5% of the candidates. Results: No significant differences were noted for the students’ performance in MCQs related to PBL (representing self-directed, small group learning tool), and TBL (representing directed-self, large group learning tool) regarding difficulty index (DI), point biserial, and distractors functionality. Conclusion: It has been observed that there is no difference in students’ performance whether PBL or TBL is used for learning Basic Medical Science courses. Small group learning such as PBL needs more resources in comparison to large group learning as in TBL, therefore any institute can decide on the adopted learning strategy depending on its resources and the number of students.

Title: Human gingival mesenchymal stem cells-lyosecretome attenuates adverse effect of hydrogen peroxide-induced oxidative stress on osteoblast cells Authors: Kusumawardani, Banun; Amin, Muhammad Nurul; Rahayu, Yani C.; Sari, Desi S.; Altariq, Morin I.; Putri, Arini H.; Kanya, Amara; Prahasanti, Chiquita; Aljunaid, Mohammed A. Abstract: Objective: To determine total protein content, antioxidant activity, and protective ability of lyophilized human gingival mesenchymal stem cells (hGMSCs)-secretome in hydrogen peroxide (H2O2) induced oxidative stress model. Methods: Human GMSCs were cultured to obtain a conditioned medium (secretome), then lyophilized to produce lyosecretome. Total protein was determined by bicinchoninic acid assay (BCA) and SDS-PAGE to improve protein measurements. Antioxidant concentration was measured by ABTS assay, while the protective ability of lyosecretome against oxidative stress was determined by the metabolic activity of osteoblast cells. The study group was divided into a control group (culture medium) and a lyosecretome treatment group (0.0; 0.157, 0.313, 0.625, 1.25, 2.5, 5, and 10 mg/mL þ H2O2). Results: Lyosecretome had a protein concentration of 2086.00 0.20 mg/ml, with a molecular weight of 174, 74, 61, 55, and 26 kDa, which are thought to facilitate cell migration, as well as bind cytokines and growth factors. Lyosecretome also provided the highest antioxidant activity of 93.51% at a concentration of 4.8 mg/ml, with an IC50 value of 2.08 mg/ml. The highest cell metabolic activity (79.53 2.41%) was shown in the 1.25 mg/ml lyosecretome treatment group. All concentrations of hGMSC-lyosecretome attenuate the adverse effect of H2O2-induced oxidative stress. Conclusion: Lyosecretome obtained from hGMSCs can maintain metabolic activity in osteoblast cells as protection against H2O2 oxidative stress.

Title: Factors influencing telehealth awareness, utilization, and satisfaction in KSA: A national population-based study Authors: Al-Shroby, Walid A.A.; Sohaibani, Imen S.; AlShlash, Nora K.; dkk. Abstract: Background: Telehealth involves delivering healthcare remotely through digital platforms such as telephone and video calls. Use of telehealth surged during the COVID- 19 pandemic because of the need for contactless healthcare. The Saudi Ministry of Health established the “937 telephone medical consultation call center” almost 10 years ago. Objectives: The aim of this study was to examine public awareness of, utilization of, and satisfaction with the 937 call center service, and to assess associated factors. Materials and methods: This national community-based, cross-sectional study was conducted through multistage sampling with proportional allocation from 20 health directorates. Participants were selected from the general population in public places and were interviewed with a validated questionnaire. Results: Of 7951 approached individuals, 7692 agreed to participate (response rate 96.7%). Seventy-eight percent of participants were aware of the 937 service, and 56.4% had previously used the service. Most (86%) users were satisfied with the service. Long waiting times were the most frequent reason (46.6%) for dissatisfaction. In multivariable analysis, service awareness and utilization were both significantly associated with having higher education (aOR 4.03, 95%CI: 3.17e5.12 and aOR 3.42, 95%CI: 2.64e4.42, respectively). Positive impressions of telephone medical consultation services, Saudi nationality, having children, having medical insurance, and having a history of chronic disease were significantly associated with awareness of, utilization of, and satisfaction with the service. Conclusion: The study revealed high awareness of, utilization of, and satisfaction with the 937 telephone medical consultation call center, thus suggesting increased public acceptance of the service. Moreover, the study identified socio-demographic factors influencing public awareness of, utilization of, and satisfaction with telehealth. Further studies are required to increase understanding of the facilitators of, and barriers to, the use of service among various population groups.

Effectiveness of telenursing in improving quality of life in patients with heart failure: A systematic review and meta-analysis

Title: Effectiveness of telenursing in improving quality of life in patients with heart failure: A systematic review and meta-analysis Authors: Ariyanto, Heri; Rosa, Elsye M. Abstract: Introduction: In the field of health services, telenursing is a contemporary information and communication technology system that enables the provision of nursing care and services to remote areas. Telenursing can increase psychological general well-being in patients with chronic conditions. Nevertheless, the effects of telenursing on patients with heart failure have not been examined. Objective: This study was aimed at ascertaining how telenursing treatments affect quality of life in patients with heart failure. Method: The inclusion criteria were articles from 2015 to 2023 in English, reporting quality of life outcomes for participants with heart failure in randomized controlled trials of telenursing interventions. The exclusion criteria were studies of psychiatric disorders, literature reviews, systematic reviews, and umbrella reviews. The systematic review was registered with PROSPERO registration number CRD42023484361. The review was conducted with five databases: PubMed, Scopus, Willey, Proquest, and Emerald Insight. Critical appraisal was conducted with the Joanna Briggs Institute’s Critical Appraisal Checklist. The data were synthesized with Review Manager version 5.4. Results: Eleven randomized controlled trials (2032 patients) met the inclusion criteria. A significant effect on quality of life was observed after telenursing intervention. The heterogeneity was high, at 98% (SMD = 1.05; 95% CI [0.12, 1.98]; r = 0.03). Conclusion: Telenursing interventions can improve quality of life among patients with heart failure and therefore may be applied in hospitals providing nursing care, to remotely provide education and monitor the quality of life of patients with heart failure.
