Abstract
Background and Aim: Air pollution has been widely established as an important risk factor for heart and respiratory diseases and mortality. The aim of this study was to compare the relationships between short-term exposure to air pollutants and hospital admissions, cardiovascular and respiratory deaths and total deaths in Ahvaz and Shahrekord, Iran.
Materials and Methods: In this ecological and time-series study data were collected on hospital admissions, cardiovascular and respiratory deaths and total deaths between 2012 and 2018. For data analysis Quasi-Poisson regression combined with linear distributed lag models were used and adjusted for trend, seasonality, temperature, relative humidity, weekdays and holidays.
Results: Data analysis showed that in Ahvaz there were statistically significant direct correlations between PM10 exposure and respiratory admissions, PM2.5 exposure and total deaths and cardiovascular admissions, O3 exposure and total deaths, and CO exposure and cardiovascular admissions. As regards Shahrekord, there were statistically significant direct correlations between PM10 exposure and respiratory deaths, PM10 exposure and cardiovascular deaths, PM2.5 exposure and cardiovascular and respiratory admissions and respiratory deaths, O3 exposure and total deaths, and CO exposure and respiratory deaths.
Conclusion: It seems there are statistically significant relationships between air pollution and hospital admissions and deaths in Ahvaz and, to a lesser extent, in Shahrekord.

Abstract
Background and Aim: Stomach cancer is of great importance in Iran due to its high incidence and mortality rates. This study aimed to evaluate the status of behavioral risk factors for stomach cancer among adults visiting healthcare centers in Kerman city in the year 2023.
Materials and Methods: This cross-sectional study was conducted on 410 adults visiting comprehensive health centers in Kerman city using a quota sampling method. A questionnaire containing demographic information and a Gastric Cancer Behavioural Risk Assessment Inventory (GC-BRAI) was provided to the participants. Independent t-tests, one-way ANOVA, and Pearson correlation tests were used for analysis. A significance level of less than 0.05 was considered.
Results: The total score for behavioral risk factors for stomach cancer was 49.54. The mean total score decreased with increasing age (p=0.007) and increased with a higher body mass index (p=0.006). Men had a significantly higher mean score than women (p<0.001). The mean total score significantly differed based on occupation (p<0.001).
Conclusion: These findings emphasize the importance of addressing modifiable risk factors for stomach cancer, particularly in individuals identified as being at higher risk according to this study.

Abstract
Background and Aim: Excessive use of antibiotics increases bacterial drug resistance in patients with diabetic foot ulcers. Therefore, the use of natural compounds as supplements may be effective in managing diabetic wound infections alongside conventional drugs. This study aimed to evaluate the effectiveness of Sarizh ointment (containing natural ingredients) on the healing of infected diabetic foot ulcers.
Materials and Methods: This single-center randomized clinical trial was conducted on patients with diabetic foot ulcers hospitalized in the infectious disease department of Imam Reza Hospital, Kermanshah. Microbial cultures were obtained from the foot ulcers of all patients using the punch method. Patients were randomly assigned to two groups: control and intervention. The control group received systemic antibiotics and a placebo dressing, while the intervention group received systemic antibiotics in addition to Sarizh herbal compounds as a supplement.
Results: A total of 30 patients with a mean age of 58.93 ± 6.15 years were included. The duration of hospitalization was 17.40 ± 3.06 days in the control group and 16.87 ± 3.52 days in the intervention group. The healing time was 17.34 ± 2.87 days in the control group and 12.06 ± 2.40 days in the intervention group. Sarizh ointment significantly reduced the healing time of diabetic foot ulcers (p = 0.001). Post-discharge bacterial cultures were negative, and complications such as redness, discharge, and pain at the wound site were similar between the two groups.
Conclusion: Sarizh ointment can be used as a complementary treatment alongside standard therapy to reduce healing time and promote wound recovery in patients with diabetic foot ulcers.

Abstract
Background and Aim: Bullying in schools remains one of the major challenges of educational systems.This study aimed to investigate the prediction of school bullying based on family atmosphere, with the mediating role of students’ sense of belonging to school.
Materials and Methods: This study employed a descriptive–correlational design using a structural equation modeling approach. The statistical population consisted of all male students enrolled in public second-level high schools in Ardabil during the 2023–2024 academic year. A sample of 200 students was selected through convenience sampling. Participants completed standardized questionnaires, including the School Bullying Questionnaire developed by Patchin et al. (2011; Cronbach’s alpha = 0.94), the Family Emotional Climate Questionnaire by Heilbrun (1964; Cronbach’s alpha = 0.86), and the School Belongingness Questionnaire by Mouton et al. (1993; Cronbach’s alpha = 0.89). Data were analyzed using descriptive statistics and structural equation modeling in SPSS version 25 and SmartPLS version 4.
Results: The results of structural equation modeling indicated that family emotional climate (β = −0.61, p < 0.001) and sense of school belonging (β = −0.57, p < 0.001) had direct and negative effects on school bullying. Additionally, family emotional climate (β = −0.17, p < 0.05) had an indirect effect on school bullying through the mediating role of sense of school belonging. The model fit indices (NFI = 0.93, SRMR = 0.07) demonstrated a satisfactory fit of the model to the data.
Conclusion: From a practical perspective and in line with the obtained results, it is recommended that psychologists and school counselors implement educational workshops focused on strengthening family relationships and teaching positive social behaviors to enhance family atmosphere and students’ sense of belonging to school.
