Introduction: The concept of lifestyle is closely related to the concept of health. Several studies have been conducted on the dimensions of health-related lifestyle in patients living with human immunodeficiency virus/acquired immunodeficiency disease (HIV/AIDS), but none has comprehensively addressed it. This study is carried out for the purposes of defining and clarifying its concept in HIV/AIDS patients. Material and methods: This study used a hybrid model of concept analysis comprising three phases; namely, a theoretical phase, field work phase, and a final analysis phase. To find relevant literature, an electronic search of valid databases was utilised using keywords related to the concept of healthrelated lifestyle. In the field work phase semi-structured interviews were performed with 12 people living with HIV/AIDS. The conventional content analysis was used in two theoretical and field work phases, and the results were combined in the final analysis phase. Results: From the sum of 1362 gained titles in theoretical phase, 71 texts were analysed and five attributes were extracted, including physical health behaviours, social and recreational activities, sexuality and fertility health, health-centred care, and distress and coping. The most important consequence of a healthy lifestyle in literature review is enhanced physical and mental health. Working in the field phase added a social interactions category to the feature of the concept. In the third phase with the combination of the results of two phases, the final definition of the concept was presented. Conclusions: Health-related lifestyle in HIV/AIDS patients is a set of behaviours that have different physio-psycho-social dimensions that people display in their individual and social lives, thereby providing their physical and mental health.

Background: SCT, considered a valid alternative to the classical evaluation method, is a distinctive method to evaluate medical students’ clinical reasoning skills. The present study aimed to determine the correlation between SCT and clinical-based classical multiple-choice questions (MCQs) in the clinical evaluation of the course of oral disease among Guilan dental students. Methods: In this analytical cross-sectional study, 73 final-year students of the dentistry school of Guilan University who had completed oral and dental diseases courses 1 to 5 were investigated. In this study, in addition to the classical MCQ test at the end of the semester, 15 SCT scenarios with three follow-up questions (45 questions in total) were also administered to the students. The difficulty and discrimination coefficients and the correlation coefficient between the SCT and MCQ tests were measured. Results: The results showed that the mean age of the students was 24.1±59.36, and 53% (39 individuals) were males. Their GPA of the previous semester was 15.42 ± 1.23. Based on the obtained results, a direct and significant relationship was found between the SCT and the MCQ scores (P=0.035); as the SCT scores increased, the MCQ scores increased accordingly. Conclusions: SCT scores were correlated with the results obtained in the classical MCQ test. It is recommended that more research on SCT be used in formative evaluations.

Background Despite all the existing guidelines regarding Covid-19, there has been less emphasis on oral care to reduce the amount of virus in the mouth and saliva and thus reduce the risk of transmission of this disease. The purpose of this study is to investigate oral hygiene habits and infection control behaviors and their relationship with the rate of family transmission in patients with covid-19. Methods In this cross-sectional analytical study, 179 patients with covid-19 referred to the Razi Medical Training Center in Rasht were examined in the form of continuous sampling in 1400–1401. The data collection tool is a 3-part questionnaire including 1) personal social and clinical information of a person infected with Covid-19, basic information from family members in contact with the infected person, and transfer to another person in the family 2) oral hygiene habits during quarantine 3) infection control behaviors. To analyze the collected data, independent t-tests, ANOVA, and Spearman's correlation were used for quantitative variables, and the Chi-square test was used for qualitative variables in SPSS software version 28, and the level of significance in all tests was 0.05. Results The findings showed that the rate of family transmission of the disease was 61.5%. There was no significant relationship between oral hygiene habits with the family transmission of Covid-19 (p = 0.108), but the use of a shared toothbrush container and a shared toothpaste tube among family members was significantly related to the rate of family transmission (p = 0.042 and p > 0.001, respectively) Conclusions There was no relationship between oral hygiene habits and the transmission of covid-19 disease in family members, but oral hygiene habits were effective in contracting a more severe form of the disease and the rate of hospitalization. The use of toothbrush containers and toothpaste tubes shared between family members increased the chance of family transmission of covid-19.
