Background Self-care and participation of patients in improving health and increasing awareness about the risk factors that affect the development of disease in patients with urinary tract stones are influential factors in controlling and improving the quality of life in these patients. In this regard, the availability and capability of smartphones increase patients’ self-care ability. The present study aimed to develop and evaluate a self-care application based on smartphones for patients with urinary tract stones. Methods The present study is a developmental and applied study that was conducted in three phases. First, the information needs and functionalities of the self-care application were determined by surveying 101 patients, 32 urologists and nephrologists, 11 nurses, and six other specialists. In the second phase, the initial sample of the smartphone-based application was created, and in the third phase, the designed application was evaluated by 15 experts using the standard Post-Study System Usability Questionnaire (PSSUQ 18.3) and Nielsen’s Attributes of Usability (NAU) questionnaire. Results of the questionnaires were entered into SPSS-23 software for analysis using descriptive statistics. Results In the first phase, 21 information elements and nine critical functionalities for the self-care application were identified, and then this application was designed by Java programming language. The evaluation of experts showed that two aspects of the quality of system user interface from the user's point of view and the overall performance of the application together obtained the highest score (6.43 from 7), which was equal to 91.85%. Then according to the experts, aspects of the degree of convenience and user-friendliness of the application received the highest score (6.10 from 7), which was equal to 87.14%, and also all aspects of the application were evaluated at an acceptable level. In general, results of the evaluation of application's usability by experts showed that the usability of the application for patients with urinary tract stones was at an acceptable level. Conclusion According to the results obtained from evaluating the smartphone-based application for patients with urinary tract stones, this self-care application can be used to prevent and control urinary tract stones and facilitate self-care and active patient participation in care.

BACKGROUND: Self-care is one of the most important principles of life and the successful treatment of patients diagnosed with cancer. Also, the first step and the most effective factor for self-care is health literacy. Thus, the aim of this study is to evaluate the relationship between level of health literacy and self-care ability in patients diagnosed with breast cancer.METHOD: Using an analytical-descriptive approach, the present study was conducted using a random access method among 120 patients diagnosed with breast cancer referring to Imam Reza Hospital of Tabriz University of Medical Sciences, during 2019. The data was gathered using two standard self-care questionnaires in patients diagnosed with breast cancer (SCHFIV6.2) and Health Literacy for Iranian Adults (HELIA). Data analysis was conducted using SPSS v22, through Pearson correlation tests and linear regression analysis.RESULTS: The results indicate a positive and significant relationship among dimensions of health literacy including access, reading, appraisal, decision, and understanding, and dimensions of self-care including self-care maintenance, self-care management, and self-care confidence. Other findings show that reading, access and decisions have a direct and significant effect on self-care ability (P-value ≤0.01).CONCLUSION: With regard to the direct and significant relationship of health literacy and self-care dimensions in patients diagnosed with breast cancer, enhancing their health literacy can result in improved self-care among them. In addition, due to the increasingly high prevalence of this disease among women, improving their health literacy can be effective in the treatment of this disease or in enhancing their quality of life.

Purpose This study aimed to identify and validate the information content and functional capabilities of a smartphone-based application for the self-care of patients with urinary tract stones. Methods and materials First, by reviewing studies and urology-oriented books, studying 214 medical records, and consulting with specialists, the information items and basic capabilities of the application were identified, and in the next stage, a researcher-made questionnaire was designed based on the information obtained from the previous step. Then, experts' opinions were considered to confirm the validity and reliability of the questionnaire; the designed questionnaire was distributed among various participants. Finally, the application's leading information elements, contents, and functional capabilities were explored by analyzing the questionnaire results. Results To conduct the survey, 101 patients with Urinary Stone Diseases (USD), 32 urologists and nephrologists, 11 nurses, and six other specialists were recruited. After analyzing the results of the filled questionnaire, 21 information elements and nine surveyed capabilities that were more important than others were selected to be used in designing the application. Some of the principal information elements that were used in the application design include: the cause of various stones in the body, clinical manifestations, laboratory results, treatments of various stones, the role of environmental factors in the treatment, the role of nutrition in the treatment and formation of stones, and different diagnostic methods. Some of the important features of the application include: medication and fluid intake reminders, laboratory test reminders, radiography and periodic examination reminders, surgical history, and easy access to medical centers for information. The mean score of information elements was 75.07 from the patients' perspective, 65.09 from the physicians' perspective, and 80.09 from the nurses' perspective. Also, the mean score of application capabilities was 31.89 from the patients' perspective, 30.37 from the physicians' perspective, and 35.09 from the nurses' perspective. The difference in the mean scores of the above variables was statistically significant (p < 0.05) in both layers. Conclusion In this study, informational and functional needs and capabilities were presented for designing a mobile-based application that helps in disease management in patients with urinary tract stones.

Background and Aims: Conventional medical training routes of bronchoscopy may decrease patients' comfort and increase procedure-related morbidity. Virtual reality (VR)-based bronchoscopy is a beneficial and safe solution for teaching trainees. The aim of this systematic review was to study the effectiveness of VR-based bronchoscopy simulators on the learning outcomes of medical trainees. Methods: Well-known sources (i.e., Scopus, ISI Web of Science, and Medline via PubMed) were systematically searched using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines on December, 2021. Peer-reviewed English papers that used VR-based simulation for bronchoscopy training were included. The articles that were studying other technologies, or those that were unrelated to the topic, were excluded. The risk of bias was assessed using the Joanna Briggs Institute checklists for quasi-experimental studies and randomized controlled trials (RCTs).Results: Out of 343 studies, 8 of them met our inclusion criteria. An appropriate control group and statistical analysis were the most common and unavoidable sources of bias in included non-RCTs, and lack of blinding in participants was the most common source of bias in RCTs. The included studies evaluated learning outcomes regarding dexterity (N = 5), speed (N = 3), the accuracy of procedures (N = 1), and the need for verbal assistance (N = 1). Based on the results, 100% (5/5) and 66% (2/3) of studies showed that the use of VR-based simulation on the learning outcomes of medical trainees led to improvement in manual ability (i.e., dexterity) and swiftness of execution (i.e., speed in performance), respectively. Additionally, improving the accuracy of subjects' performance, and reducing the need for verbal guidance and physical assistance was reported in studies that evaluated these variables. Conclusion:VR bronchoscopy simulator as a training method for teaching medical trainees, especially for novices has the potential to improve medical trainees' performance and reduce complications. Further studies are needed to evaluate the positive effects of VR-based simulation on the learning outcomes of medical trainees.
