COVID-related psychological distress fully mediates the association from social impact to sleep disturbance among patients with chronic schizophrenia.

The aims of the current study were to identify factors associated with sleep disturbance and Coronavirus disease-19 related psychological distress (CPD), and to develop a conceptual model to verify the mediating effect of CPD on the association between social impact and sleep disturbance. This study recruited patients with schizophrenia. Factors associated with the level of sleep disturbance and CPD were identified using univariate linear regression, and further selected into a stepwise multivariate linear regression model. Using structural equation modeling, a mediation model was developed to test the mediating effect of CPD on the association between social impact and sleep disturbance. After estimating with the stepwise and bootstrap regression, higher levels of CPD were associated with higher levels of social anxiety and subjects without a regular diet. Sleep disturbance was associated with a higher level of social anxiety, a history of psychological trauma, chronic disease, and those who did not smoke. The final model confirmed the mediating effects of CPD; whereas, the direct effect from social impact to sleep disturbance did not reach statistical significance. The current study manifests the crucial role of CPD on the association between social impact and sleep disturbance, and timely intervention for CPD is warranted.

The impact of the COVID-19 pandemic on negative symptoms in individuals at clinical high-risk for psychosis and outpatients with chronic schizophrenia.

Negative symptoms are core features of schizophrenia-spectrum disorders that are frequently observed across all phases of illness. By their nature, COVID-19 social isolation, physical distancing, and health precautions induce behavioural aspects of negative symptoms. However, it is unclear whether these prevention measures also lead to increases in experiential negative symptoms, whether such effects are equivalent across individual negative symptom domains, and if exacerbations occur equivalently across phases of illness. The current study compared negative symptom severity scores obtained during the pandemic to pre-pandemic assessments in two samples: (1) outpatients with chronic schizophrenia (SZ: n = 32) and matched healthy controls (CN: n = 31) and (2) individuals at clinical high risk for psychosis (CHR: n = 25) and matched CN (n = 30). Pre-pandemic ratings of negative symptoms were clinically elevated in SZ and CHR groups, which did not differ from each other in severity. In SZ, ratings obtained during the pandemic were significantly higher than pre-pandemic ratings for all 5 domains (alogia, blunted affect, anhedonia, avolition, and asociality) and item-level analyses indicated that exacerbations occurred on both experiential and behavioral symptoms of anhedonia, avolition, and asociality. In contrast, CHR only exhibited increases in anhedonia and avolition items during the pandemic compared to pre-ratings. Findings suggest that negative symptoms should be a critical treatment target during and after the pandemic in the schizophrenia spectrum given that they are worsening and critically related to risk for conversion, functional outcome, and recovery.

Peripandemic psychiatric emergencies: impact of the COVID-19 pandemic on patients according to diagnostic subgroup.

On March 11th, 2020, the outbreak of coronavirus disease 2019 (COVID-19) was declared a pandemic. Governments took drastic measures in an effort to reduce transmission rates and virus-associated morbidity. This study aims to present the immediate effects of the pandemic on patients presenting in the psychiatric emergency department (PED) of Hannover Medical School. Patients presenting during the same timeframe in 2019 served as a control group. A decrease in PED visits was observed during the COVID-19 pandemic with an increase in repeat visits within 1 month (30.2 vs. 20.4%, pBA = 0.001). Fewer patients with affective disorders utilized the PED (15.2 vs. 22.2%, pBA = 0.010). Suicidal ideation was stated more frequently among patients suffering from substance use disorders (47.4 vs. 26.8%, pBA = 0.004), while patients with schizophrenia more commonly had persecutory delusions (68.7 vs. 43.5%, pBA = 0.023) and visual hallucinations (18.6 vs. 3.3%, pBA = 0.011). Presentation rate of patients with neurotic, stress-related, and somatoform disorders increased. These patients were more likely to be male (48.6 vs. 28.9%, pBA = 0.060) and without previous psychiatric treatment (55.7 vs. 36.8%, pBA = 0.089). Patients with personality/behavioral disorders were more often inhabitants of psychiatric residencies (43.5 vs. 10.8%, pBA = 0.008). 20.1% of patients stated an association between psychological well-being and COVID-19. Most often patients suffered from the consequences pertaining to social measures or changes within the medical care system. By understanding how patients react to such a crisis situation, we can consider how to improve care for patients in the future and which measures need to be taken to protect these particularly vulnerable patients.

Influence of social isolation caused by coronavirus disease 2019 (COVID-19) on the psychological characteristics of hospitalized schizophrenia patients: a case-control study.

Coronavirus disease 2019 (COVID-19) has been classified as a pandemic, and mental hospitals located in epidemic centers have been affected. Social isolation is an important and irreplaceable measure to control the spread of the epidemic. In this study, schizophrenic patients who were subjected to social isolation after close contact with COVID-19 patients were used as participants to explore the impact of social isolation on common inflammatory indicators and psychological characteristics. A total of 30 patients with schizophrenia were recruited from Wuhan Mental Health Center. In addition, 30 ordinary schizophrenic patients were matched with the isolation group and were recruited from another branch of Wuhan Mental Health Center as controls. We compared the differences in common inflammatory indicators and psychological characteristics between the isolated group and the control group, and longitudinal comparison of the differences in the above indicators before and after isolation among the isolation group. The Chinese Perceived Stress Scale (CPSS) score, Hamilton Depression Scale (HAMD) score and Hamilton Anxiety Scale (HAMA) score of the isolation group were significantly higher than those of the control group (p = 0.00, 0.00, 0.00, respectively). The C-reactive protein (CRP) level, CPSS score, HAMA score and Pittsburgh sleep quality index (PSQI) score of the isolation group were significantly higher after isolation (p = 0.01, 0.00, 0.00, 0.00, 0.00, respectively). Inpatients of schizophrenia suffered from social isolation due to COVID-19 have a severe psychological burden. Social isolation caused patients to develop a weak inflammatory state and led to worse anxiety and sleep quality.

A Longitudinal Investigation of the Effects of the COVID-19 Pandemic on the Mental Health of Individuals with Pre-existing Severe Mental Illnesses.

OBJECTIVE: Individuals with severe mental illnesses (SMI), including schizophrenia spectrum illnesses and affective disorders, may be at increased risk for negative mental health outcomes related to the COVID-19 pandemic. This study compared the severity of pre-pandemic symptoms and affective experiences to current symptoms to evaluate this possibility. METHODS: 148 individuals with SMI (92 with schizophrenia spectrum illnesses and 56 with affective disorders) were recruited from ongoing ecological momentary assessment studies that sampled day-to-day experiences and symptom severity prior to the pandemic. Participants completed a one-time phone survey that queried these same experiences/symptoms between April and June of 2020. RESULTS: Severity of affective experiences and psychotic symptoms remained stable across time, as did sleep duration. Well-being and the number of substances used increased during the early months of the pandemic. Increases in well-being were associated with being female and spending less time alone pre-pandemic. Patterns of stability/change did not differ according to diagnostic category. CONCLUSIONS: At this relatively early stage, individuals with SMI are not reporting a worsening of symptoms or affective experiences and instead appear to be resilient in the face of the pandemic. Continued assessment is needed to determine whether this resilience will persist as the pandemic progresses.

End-of-life decision-making capacity in an elderly patient with schizophrenia and terminal cancer.

Medical practitioners are confronted daily with decisions about patients' capacity to consent to interventions. To address some of the pertinent issues with these assessments, the end-of-life decision-making capacity of a 72-year-old female with treatment-resistant schizophrenia and terminal cancer is discussed, as are the role of the treating clinician and the importance of health-related values. There is a recommendation that the focus of these assessments can rather be on practical outcomes, especially when capacity issues arise. This implies that the decision-making capacity of the patient is only practically important when the treatment team is willing to proceed against the patient's wishes. This shifts the focus from a potentially difficult assessment to the simpler question of whether the patient's capacity will change the treatment approach. Clinicians should attend to any possible underlying issues, instead of focusing strictly on capacity. Compared to the general populations people with serious mental illness (SMI) have higher rates of physical illness and die at a younger age, but they do not commonly access palliative care services. Conversations about end-of-life care can occur without fear that a person's psychiatric symptoms or related vulnerabilities will undermine the process. More research about palliative care and advance care planning for people with SMI is needed. This is even more urgent in light of the coronavirus disease-2019 (COVID-19) pandemic, and South African health services should consider recommendations that advanced care planning should be routinely implemented. These recommendations should not only focus on the general population and should include patients with SMI.

The effect of childhood trauma on age of onset in patients with schizophrenia.

PURPOSE: Childhood trauma (CT) has been shown to affect the etiology and clinical features of schizophrenia. In this study, it was aimed to investigate the effects of CT on the age of onset (AoO) and clinical features of the disease by considering factors such as family history, head trauma, birth trauma, alcohol and substance abuse that may affect AoO of the disease. METHODS: The sample comprising 200 patients admitted to the outpatient and inpatient care at the Izmir Katip Çelebi University, Atatürk Education and Research Hospital psychiatry clinic, were included in the study. Socio-demographic information form, Positive and Negative Syndrome Scale (PANSS), Childhood Trauma Questionnaire-Short Form (CTQ-SF) and subscale of Mini-International Neuropsychiatric Interview (MINI) were applied. RESULTS: All types of trauma, except physical abuse, were found related to the disease onset age earlier. It was also detected that the factors of head trauma, birth complication, presence of an individual diagnosed with schizophrenia in the family and migration history were not related to AoO of the disease. On the other hand, it was found that physical, emotional and sexual abuses lead to more positive psychotic symptoms, and all types of CT increase the severity of disease and the risk of suicide. CONCLUSION: This study draws attention to the etiological importance of CT in schizophrenia as an environmental factor by showing that it affects AoO of the disease along with symptomatology. Future studies should focus on the pathogenesis of CT in schizophrenia and the interaction between CT and biological and genetic predisposition.

The COVID-19 Global Pandemic: Implications for People With Schizophrenia and Related Disorders.

The coronavirus disease-19 (COVID-19) global pandemic has already had an unprecedented impact on populations around the world, and is anticipated to have a disproportionate burden on people with schizophrenia and related disorders. We discuss the implications of the COVID-19 global pandemic with respect to: (1) increased risk of infection and poor outcomes among people with schizophrenia, (2) anticipated adverse mental health consequences for people with schizophrenia, (3) considerations for mental health service delivery in inpatient and outpatient settings, and (4) potential impact on clinical research in schizophrenia. Recommendations emphasize rapid implementation of measures to both decrease the risk of COVID-19 transmission and maintain continuity of clinical care and research to preserve safety of both people with schizophrenia and the public.
