ABSTRACT

Background and Objective: The unprecedented spread of infectious diseases, such as the COVID-19 pandemic, in psychiatric units has affected the self-efficacy, burnout, and job performances of psychiatric nurses. We conducted a survey to investigate the moderating effect of burnout on the relationship between the self-efficacy and job performances of psychiatric nurses. Materials and Methods: Validated and structured questionnaires were used to collect data from 186 nurses in psychiatric units for COVID-19. The data were analyzed using descriptive statistics, Pearson's correlation coefficient, and a series of multiple linear regression analyses based on Baron and Kenny's method using the SPSS 26.0 program. Results: Job performance was positively correlated with self-efficacy (r = 0.75, p < 0.001) but had no significant correlation with burnout (r = -0.11, p = 0.150). Self-efficacy was negatively correlated with burnout (r = -0.22, p = 0.002). Burnout among psychiatric nurses had significant moderating effects on self-efficacy and job performance (ß = -0.11, p = 0.024). Conclusions: These findings indicate a need to prevent burnout and to enhance self-efficacy in psychiatric nurses to increase their job performances and serve as a basis for establishing strategies to deploy medical staff in the future.

ABSTRACT

BACKGROUND: The effect of antipsychotics adherence on the risk of cardiovascular disease (CVD) among schizophrenia patients has not been studied. While antipsychotic adherence is favorable for all-cause mortality, its association with CVD incidence is unclear due to the potential risk of CVD caused by antipsychotics. METHODS: Using the Korean National Health Insurance Service Database, we constructed a case-cohort of 80,581 newly-diagnosed schizophrenia patients between 2004 and 2013 from a cohort of all Koreans 20-40 years old. Patients were divided into quartiles by adherence determined by their two-year medication possession ratio. Patients were followed from two years following the diagnosis of schizophrenia until Dec. 31st, 2017 for the primary outcome of incident CVD and secondary outcomes of stroke, myocardial infarction, and all-cause mortality. Cox proportional hazards analysis was performed adjusting for conventional risk factors. OUTCOMES: Newly diagnosed schizophrenia patients were followed for a median of 7.0 years resulting in 1396 incident CVD cases over 5.73 × 105 person-years. When adjusted for potential confounders, the best adherence quartile group had significantly lower risk of CVD (HR, 95%CI; 0.78, 0.66-0.92; p-trend, 0.003), stroke (HR, 95%CI; 0.79, 0.66-0.94; p-trend, 0.015), and all-cause mortality (HR, 95%CI; 0.86, 0.78-0.95; p-trend, 0.003) compared to the worst adherent quartile group. Subgroup analysis by antipsychotics generation, concurrent medication, and comorbidities did not significantly alter results. INTERPRETATION: Among newly diagnosed schizophrenia patients, better adherence to antipsychotics lowered the risk CVD incidence despite previously suggested antipsychotic-associated CVD risk. Thus, efforts to improve antipsychotics adherence may improve CVD outcomes in schizophrenia patients.

ABSTRACT

OBJECTIVE: Although comorbid panic disorder is associated with more severe symptoms and poorer therapeutic response in depressive patients, the relationship between panic disorder and risk of suicide attempt has not been confirmed. This study aimed to examine the relationship between comorbid panic disorder and clinical characteristics associated with suicidal risk as well as the likelihood of suicide attempt. METHOD: A total of 223 outpatients with current major depressive disorder participated in the study. Both subjects with panic disorder (33%) and those without panic disorder (67%) were compared based on history of suicide attempts, current psychopathologies, and traits of impulsivity and anger. RESULTS: Subjects with panic disorder had higher levels of impulsivity, depression, and hopelessness and were more likely to report a history of suicide attempts. Subjects with panic disorder were younger at the time of first suicide attempt than those without panic disorder. Logistic regression analyses indicated that comorbid panic disorder was significantly associated with a history of suicide attempts after adjusting for other clinical correlates (odds ratio = 2.8; p < 0.01). CONCLUSIONS: These findings suggest that comorbid panic disorder in patients with major depressive disorder may be associated with a more severe burden of illness and may independently increase the likelihood of suicide attempt.

ABSTRACT

BACKGROUND: The influence of childhood adversity on depression is modulated by genetic vulnerability. The apolipoprotein E ε4 (APOE-ε4) allele is a strong genetic risk factor for Alzheimer's disease (AD). Because late-life depressive symptoms could be a part of the preclinical course of AD, the APOE-ε4 allele may contribute to depression in old age. OBJECTIVE: The aim of this study was to evaluate whether an APOE-ε4 carrier status was associated with depressive symptoms in older adults and to detect the gene-environment interaction between APOE-ε4 status and childhood adversity in relation to depressive symptoms in old age. METHOD: The participants consisted of 137 older adults (age range 50-70) without any psychiatric history or clinically significant cognitive impairment. APOE genotypes and measures of childhood adversity and depressive symptoms were obtained. RESULTS: There was a significant positive association between adverse childhood experiences (ACE) scores and depressive symptoms (B=0.60; 95% CI=0.26, 0.93 for a 1 score increase in ACE scores; p=0.001). Although APOE-ε4 status per se was not associated with depressive symptoms, there was a significant interaction of the ACE scores with the APOE genotype in relation to depressive symptoms (B=0.78; 95% CI=0.02, 1.55; p=0.044). There was a significantly higher effect of childhood adversity on depressive symptoms in APOE-ε4 carriers than non-carriers (t=2.13, p=0.035). CONCLUSIONS: Our results suggest that the APOE-ε4 may modulate the association between childhood adversity and depressive symptoms in older adults. However, more research in a larger sample is needed to gain a better understanding of the relationship between the APOE-ε4, childhood adversity, and depression.

ABSTRACT

BACKGROUND: Suicide attempters treated in emergency rooms were studied in order to understand the motives behind this behavior. Disparities between the etiological contributions to suicidal ideation, intention, and action were examined in order to characterize motives in these categories. METHODS: Suicide attempters who visited the emergency departments of seven university hospitals were analyzed. Attempts leading to mortality were excluded from the analysis. Participants were assessed using semi-structured questionnaires, the results of which were noted on their medical records. These were analyzed retrospectively. RESULTS: Attempter self-report assessment revealed that participants chose external sources of stress (75.4%) and psychiatric symptoms (19.1%) as their main reasons for attempting suicide. However, assessments by interviewers indicated that stressors contributed to suicide attempts to a lesser degree (52.8%) while psychiatric symptoms were more etiologically relevant (36.6%). Compared to those with stressors that was identified as causal in both self-report and clinician assessed evaluation, the participants-regardless of their self-report evaluation-who identified with causal psychiatric symptoms by psychiatrist had more severe and intense suicidal ideation and more determined suicidal intention. LIMITATIONS: We collected samples from only university hospitals, resulting in selection bias. In addition, we did not use psychiatric scales to evaluate the participants׳ symptoms. CONCLUSIONS: Stress was the greatest motive for attempting suicide, affirmed in both self-report and clinician assessed evaluation. A fair proportion of people were objectively identified as being motivated by psychiatric symptoms, yet were unaware of what they suffered from. Furthermore, suicide severity, intensity, and suicidal intention were stronger in psychiatrically driven cases.
