OBJECTIVE:Vitamin D is thought to be deficient in patients with bipolar disorder. The purpose of this study is to use latent profile analysis to identify the patterns of vitamin D levels in patients with episodes of bipolar depression, and to examine the relationship among these latent profiles and demographic and clinical characteristics. METHODS:A total of 149 patients diagnosed with bipolar depression were selected in Guangzhou, China. Depression was evaluated by Zung Self-Rating Depression Scale. Serum 25-hydroxyvitamin D levels tested at baseline and after two weeks of psychiatric treatment were included in the latent profile analysis to identify subgroups. P-trend analysis was used to assess the association between subgroups and depression improvement. Multinomial logistic regression analysis was used to assess the influencing factors of subgroups. RESULTS:A three-profiles solution was found to demonstrate the best fit [low-level profile (32.9%), medium-level profile (51.0%), and high-level profile (16.1%)]. There was a significant nonlinear relationship between depression improvement and vitamin D high-level profile, compared to medium-level profile (P for trend <0.05). In multinomial logistic regression analysis, baseline and post-treatment SDS scores, admission season, age, and body mass index significantly affect the profile membership. CONCLUSIONS:This study found that individuals with high levels of vitamin D showed a significant improvement in depression severity. However, those with low levels of vitamin D remained deficient, indicating a need for targeted vitamin D supplementation. Our findings may provide valuable insights for designing tailored vitamin D supplement interventions to address vitamin D deficiency in bipolar depression.

Objective. This study focused on mood regulations and their association with sociodemographic status, exercise pattern, and physical conditions of adults and older adults in China who did not undergo interventions. Method. Data were based on the 2016 to 2018 Guangdong National Physique Monitoring data, in which 5242 participants aged 20-69 years were recruited. Multiple statistical analysis methods, such as descriptive and logistic regression analyses, were used to study each exercise motivation and its association with influencing factors, including sociodemographic characteristics, exercise measurements, and physical conditions. An exercise index for mental health was also used to investigate the number and types of people who were more likely to meet the index. Results. We observed that 44.9% (2355/5242) of participants did not engage in physical exercise in this study. Only older participants (40 to 69 years old) and those with an average level of education (high school/technical secondary school) showed a significant association with exercising for mood regulation. Few people met the index that is good for mental health (16.64% [872/5242] met index 1, and 2.84% (149/5242) met index 2), and higher education showed a significant association with a reduction in the mental health burden and the prevention of depression. Conclusion. This study found that motivating people to be more active and educating them on the potential mental health benefits of exercise could help them to exercise more.

Objectives To survey anxiety and depression symptoms to COVID-19 outbreak in the public, medical staff and patients during the initial phase of the pandemic. Design Cross-sectional online survey administered through WeChat Mini Program using Chinese versions of Zung Self-rating Depression Scale and Zung Self-rating Anxiety Scale. Setting Guangzhou, China. Participants 47 378 public, 1512 medical staff and 125 patients with COVID-19. Results Higher rates of depression (47.8%) and anxiety symptoms (48.7%) were shown by patients who were screened positive compared with those of the public (35.6%, 25.7%) or medical staff (15.4%, 13.3%). The professional identity of a nurse, conditions of ‘with an infected family member’ and ‘working at the frontline’ were risk factors to depression or anxiety symptoms for the medical staff. Younger age, lower educational level, female and not having adequate masks were the risk factors for the public. Conclusion The COVID-19 outbreak increased people’s depression or anxiety emotion responses, which varied extensively among the patients, public and medical staff.

Objectives: The long-term outcome of childhood-onset schizophrenia (COS) and its influencing factors remain unclear. The current study aimed to assess the long-term outcomes of COS and identify possible outcome predictors. Methods: We retrospectively investigated 276 patients with COS. Diagnosis made according to the ICD-10 criteria for schizophrenia, and the age of the first onset was ≤ 14 years. Follow-up was completed for 170 patients, with a median follow-up period of 5.6 years. Outcome variables included occupational/education status and readmission. Spearman correlation was performed to assess the relationship between predictors and outcome variables. Binary logistic regression was conducted to detect possible predictor variables for outcome variables. Results: At the end of the follow-up, 89 patients (52.3%) were at school, 70 patients (41.2%) were employed, and only 11 patients (6.5%) were dropped out of school or unemployed. The duration to the first admission and depressive symptoms were identified as predictors of occupational/educational status. The length of follow-up and obsessive-compulsive symptoms (OCS) were distinguished as predictors of readmission. Duration to the first admission and length of follow-up were risk factors, and depressive symptoms and OCS were protective factors for the outcomes of COS. Conclusion: We found a favorable long-term outcome on occupational/education status in COS, and depressive symptoms and OCS may be associated with more positive long-term outcomes in COS. Our findings suggest that COS patients may benefit from early intervention and require appropriate treatment.

@# Emergencies refer to those events that cause serious social harm, including natural disasters and public health events, and require emergency response. Medical rescue team is the main emergency rescue team. While carrying out the rescue mission, they are under great pressure both physically and mentally due to the unadaptability of the rescue environment, the lack of protective materials, overwork and other reasons, often resulting in fear, tension, anxiety, pessimism, self-blame and even acute stress disorder. Without timely and effective psychological support, long-term psychological problems such as post-traumatic stress disorder will remain after the event. Comprehensive psychological support includes psychological measurement of the whole rescue process, team formation before rescue and detailed psychological support intervention training, self-relaxation during rescue, basic life and safety guarantee, drug treatment, online psychological assistance, withdrawal of stressors after rescue and lifestyle reconstruction.

Background: This study focused on different exercise motivations, especially mood regulation and their relation to the sociodemographic status, exercise pattern and physical conditions of adults and older adults in China who did not undergo interventions.Methods: A total of 5242 participants aged 20-69 years from 2016 to 2018 were recruited in this cross-sectional study to finish the questionnaire of Guangdong National Physique Monitoring organized by the Guangzhou Institute of Sports Science. Multiple statistical analyses methods were used to study each exercise motivation and its sociodemographic characteristics (gender, age, education and job), exercise measurements (frequency, duration and intensity) and physical conditions (BMI, abdominal obesity and basic diseases). An exercise index that is good for mental health (index 1: 45 min per session and 3-5 times per week; index 2: exercise motivation of mood regulation and exercise 60-120 min per week) was also used to investigate the number and type of people who were more likely to meet the index. Results: In our study, 44.9% (2355/5242) of participants showed exercise inactivity. No gender difference was observed among those who exercised for mood regulation. Only older participants and those with an average level of education showed a significant association with mood regulation. Few people met the index that is good for mental health (16.64% (872/5242) met index 1 and 2.84% (149/5242) met index 2), and higher education showed a significant association with a reduction in the mental health burden and the prevention of depression. Conclusion: This investigation suggests motivating people to be more active, educating people on the mental health benefits of exercise.
