Background: High prevalence of smartphone addiction among medical students may contribute to adverse physical and mental health outcomes. Aim: To estimate the prevalence of smartphone addiction, and explore the influencing factors and related mental health symptoms of smartphone addiction among Asian medical students. Design: Systematic review and meta-analysis. Methods: PubMed (MEDLINE), the Cochrane Central Register of Controlled Trials, and EMBASE were searched for relevant literature from the inception to September 10, 2021. Using Stata software 11.0, the meta-analysis of prevalence and the influencing factors of smartphone addiction were determined with 95% confidence intervals. Results: Nineteen articles, published between 2014 and 2019, were included, producing medical student studies from seven different Asian countries. The included studies were conducted in India ( n = 11) and Malaysia ( n = 3), with China, Saudi Arabia, Turkey, Nepal, and Iran each contributing one study. Among a total of 5,497 medical students, the participants included 3,214 females, of whom 2,181 were medical students with smartphone addiction. The prevalence of smartphone addiction among Asian medical students was 41.93% (95% CI [36.24%, 47.72%]). The influencing factors of smartphone addiction among medical students included gender, duration of smartphone use, smartphone function, and marital status. Ten studies (52.63%) explored related mental health symptoms of smartphone addiction among Asian medical students. Smartphone addiction was positively correlated with poor sleep quality ( r = .17–.31), stress ( r = .30–.40), anxiety, depression, neuroticism, and general health among Asian medical students. Conclusion: Smartphone addiction is highly prevalent among Asian medical students. Smartphone addiction may adversely affect mental health, resulting in sleep disturbance, stress, anxiety, depression, and neuroticism. It is necessary to take appropriate precautionary actions and interventions to prevent smartphone overuse among medical students.

ObjectivesEmergency department physicians and nurses are at high risk of compassion fatigue, burnout and depression. The purpose of this study was to examine the inter-relationship between compassion fatigue, burnout, compassion satisfaction and depression in emergency department physicians and nurses.DesignA cross-sectional study.SettingThis study was conducted in five tertiary hospitals in five different cities across the province of Sichuan, China, in 2021.ParticipantsA total of 342 emergency department physicians and nurses participated in the study.Main outcome measuresCompassion fatigue, burnout, compassion satisfaction and depression scores.ResultsAmong the study participants, 100% were found to have depressive symptoms, 27.8% had low compassion satisfaction, 2.3% had high burnout and 3.8% had compassion fatigue. In the final multiple linear regression model, marital status (p=0.008; 95% CI –5.205 to –0.789), history of chronic disease (p=0.003; 95% CI –6.461 to –1.386), compassion satisfaction (p<0.001; 95% CI 0.593 to 1.274), burnout (p=0.019; 95% CI 0.084 to 0.930) and compassion fatigue (p<0.001; 95% CI –1.527 to –1.053) among emergency department physicians and nurses were considered to be significant predictors of depression.ConclusionsThe prevalence of depression among emergency department physicians and nurses is high in the province of Sichuan, China. Compassion fatigue, burnout and compassion satisfaction were significantly associated with depression in emergency department physicians and nurses. Hospital administrations should consider these findings to develop appropriate psychological interventions and strategies, to prevent, alleviate or treat severe depression among emergency department physicians and nurses in the province of Sichuan.

Aim To explore the levels of mobile phone addiction and burnout and their relationships among novice nurses. Design A cross‐sectional investigation design. Methods Questionnaires were distributed to 400 novice nurses in five public hospitals in China. A total of 366 participants completed the survey. Data collected in 2020 were analysed by using descriptive statistics, an independent t test and Pearson's correlation analysis. Results The results showed that the frequency of nursing adverse events was associated with higher level of mobile phone addiction in novice nurses, and 52.46% of the participants ( N = 366) presented a high level of occupational burnout. Moreover, the results indicated that there was a positive correlation between the novice nurses’ mobile phone addiction level and burnout ( r = .33, p < .01). Conclusion The level of mobile phone addiction may affect nursing adverse events and nurses’ burnout. Education on novice nurses’ mobile phone use seems necessary to ensure patient safety and burnout prevention. Impact Findings of this study expanded important knowledge about mobile phone addiction and its potential influence on nursing safety and nurse burnout and may place significant implications to staff nurse management and in‐service education.

Previous findings suggest that the Papez Circuit may have a role in major depressive disorders. We used atlas-based tract-specific quantification analysis and voxel-based analysis to examine the integrity of white matter tracts involved in mood regulation (including tracts in the Papez Circuit). Diffusion tensor imaging acquired from 35 first-episode, treatment-naive adults with major depressive disorders and 34 healthy adult controls were compared. Our statistical approach compared structural integrity of 11 major white matter tracts between the major depressive disorder and adult controls, as well as illness duration influence in patients. Fractional anisotropy was decreased in the hippocampal cingulum and in the anterior thalamic radiation according to both analytical approaches, all of which were important tracts included in the Papez Circuit. Our results support the role of the Papez Circuit in major depressive disorders with the minimal probability of false positive due to similar findings in both analyses that have complementary advantages. Dysfunction of the Papez Circuit may be a potential marker for studying the pathogenesis of major depressive disorders.
