Personality traits and college students' internet addiction: The mediating roles of general health and self-esteem.

This research aimed to explore the gender-related differences in Internet addiction levels, the associated factors behind Internet addiction, and the mediating roles of general health and self-esteem in the relationship between personality traits and Internet addiction among college students. A total of 318 college students in Iran participating in this study completed sociodemographic information form and self-report measures of Internet addiction, personality traits, general health, and self-esteem. The results showed higher frequencies of low and moderate-severe levels of addiction among female and male students, respectively. Further, younger age, male gender, singleness, high scores on neuroticism, poor general health, and low self-esteem might be linked to Internet addiction. The overall hypothesis that general health and self-esteem mediated the effect of neuroticism on Internet addiction was also supported. Our findings highlighted the necessity of evaluating general health and self-esteem among Internet-addicted students. Further, these variables can be targeted by psychiatrists and psychologists for effective cognitive-behavioral therapy among Internet-addicted students.

Serum level of stem cell factor and its soluble receptor in aspirin-exacerbated respiratory disease.

Aim: Stem cell factor (SCF) may be associated with inflammatory processes leading to aspirin-induced asthma. This study evaluated the relationship between serum level of SCF and its soluble receptor with aspirin-induced asthma. Methods & materials: Twenty-five patients and 25 healthy controls were enrolled in this study. The concentration of SCF and mast/stem cell growth factor receptor (C-kit) was determined in serum samples. Spirometry and rhinometry were performed to determine the severity of the disease. p < 0.05 were considered significant. Results: The serum levels of SCF and C-kit receptor were significantly higher in the case group. The serum SCF and C-kit level had a significant positive correlation with the severity of asthma, disease duration and nasal obstruction. Conclusion: Our findings suggest that SCF and C-kit receptors have a direct effect on the severity of aspirin-induced asthma.
