Background: Suicidal behavior including suicidal ideation (SI) and suicide attempts (SA) is a common clinical feature of adolescent patients with major depressive disorders (MDD). We hypothesized that differences in functional connectivity density (FCD) exist between adolescent patients with SA and SI, and aimed to investigate the different suicidal behaviors in adolescents patients with MDD17. Methods: 37 MDD adolescents with SA, 34 MDD adolescents with SI, 20 MDD adolescents without SA and SI (non-suicidal group), and 20 adolescents healthy controls (HC) were enrolled in this study. All participants were scanned using functional magnetic resonance imaging (fMRI) to evaluated the FCD. Between-group differences of all variables were analyzed. The relationships between FCD values and clinical scale scores were also analyzed. Results: The FCD of the left inferior occipital gyrus in the SI group was higher than those in the other groups. The FCD in the SA group was higher than that in the control group. The FCD of the right dorsolateral superior frontal gyrus in the SI group was lower than that in the other three groups. The FCD values of the left precentral gyrus in the SI group were higher than those in the other three groups. The left inferior occipital gyrus FCD positively correlated with the suicide factor score of Hamilton Depression Scale (HAMD), and the right dorsolateral superior frontal gyrus negatively correlated with the HAMD suicide factor score but not with the HAMD total score. Conclusion: Changes in FCD in adolescent patients with depression and SI can reflect changes in functional connections in the brain. [ABSTRACT FROM AUTHOR]

Background: Mental health symptoms such as anxiety, depression, stress, and burnout are common among healthcare workers. However, the interconnections among them remain under-explored. This study aimed to address the interrelationships among these symptoms in psychiatric nurses. Methods: We conducted a nationwide survey in the early stage of the COVID-19 pandemic (January to March 2021) to investigate the interconnectedness of depression, anxiety, stress, and burnout among psychiatric nurses. Using network analysis, we identified central symptoms, important bridge symptoms, and the correlations among these central symptoms. Results: Of the 9,224 psychiatric nurses (79.2% female) included in the statistical analyses, 27.6% reported clinically significant depression, 31.2% anxiety, 14.5% stress, and 23.8% burnout. Network analysis revealed that stress had the highest expected influence (EI) value (0.920) and the highest strength among all nodes. The node for depression scored the highest in both closeness and betweenness. Emotional exhaustion (EE) had the highest bridge expected influence (BEI) of 0.340, with the strongest intergroup association between EE and depression. No significant differences were found in gender or frontline work experience (all p > 0.05). Conclusions: Burnout, depression, anxiety, and stress are relatively common among psychiatric nurses in the context of the COVID-19 pandemic. While anxiety was the most prevalent, stress emerged as the core symptom, and depression as an important bridging node. Interventions targeting the core symptoms and bridging nodes may improve the mental health of psychiatric nurses. [ABSTRACT FROM AUTHOR]

To investigate the association between mental health symptoms, alcohol use, and alcohol misuse among psychiatrists in China during the early stage of the COVID-19 pandemic. We conducted an online survey to collect data regarding mental health symptoms and alcohol use among psychiatrists in early 2020. The Depression Anxiety Stress Scale-Chinese Version (DASS-21) was used to assess depression, anxiety, and stress symptoms, and the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) was used to assess alcohol use. In total, 3774 psychiatrists completed the survey. AUDIT-C scores were positively correlated with DASS total and depression, anxiety, and stress subscales (total: r = 0.015, depression: r = 0.121, anxiety: r = 0.103, and stress: r = 0.096, all p < 0.05). Alcohol misuse was associated with male sex (OR = 4.754), cigarette smoking (OR = 2.441), administrative position (OR = 1.811), depression (OR = 1.489), and stress (OR = 1.504). Those who reported increased alcohol use during the pandemic were more likely to be male (OR = 2.174), endorse anxiety symptoms (OR = 2.386), or increased stress (OR = 2.402). Mental health symptoms were common among psychiatrists during the COVID-19 pandemic. Depression and stress symptoms were significantly associated with alcohol misuse. Anxiety and stress symptoms were associated with reported increases in alcohol use. Though a causal relationship cannot be inferred, our findings suggest that strategies promoting healthcare professionals' mental well-being should include alcohol use. • Depression and stress symptoms were significantly associated with alcohol misuse. • Anxiety and stress symptoms were associated with reported increases in alcohol use. • Though a causal relationship cannot be inferred, our findings suggest that strategies promoting healthcare professionals' mental well-being should include alcohol use.
