Relationship between stressful life events, coping styles, and schizophrenia relapse

Risk factors and strategies for relapse prevention among individuals living with serious mental illness in South Africa: Qualitative inquiry from patients' and caregivers' perspectives

INTRODUCTION

Relapse among individuals with serious mental illnesses in resource-limited contexts, including South Africa, is a significant concern. To date, the risks for relapse among this population is well documented, but little is known about prevention strategies to reduce its occurrence in these resource-limited settings. Therefore, this qualitative study explores the risk factors and strategies for relapse prevention from the patients' and caregivers' perspectives.

METHODS

We conducted audio-recorded face-to-face in-depth interviews to capture the lived experience of relapse of inpatient study participants with serious mental illness (N = 24) at a public specialized psychiatry hospital in South Africa and their caregivers (N = 6). We conducted an inductive thematic analysis with two pre-specified themes (risk factors for relapse and strategies for prevention), with the codes devised from the data.

RESULTS

Six sub-themes were identified from the analysis within the two pre-specified themes(Risk factors and strategies for relapse prevention): personal-related, family-related, and health system-related risk factors and strategies for preventing relapse, respectively. To highlight some essential findings, the importance of motivation for drug adherence, family involvement, and availability of anti-psychotic drugs in public health care were noted. More importantly, this study identified important cultural complexities where traditional healers play a significant role in some cultural understanding and treatment of mental illness, affecting medication adherence.

CONCLUSION

This study calls for people-centered mental health care delivery in a public health system that listens to the voice of concern, including cultural challenges, and implements meaningful support that matters most to the patient and their family/caregivers.

Associations of schizophrenia with the activities of the HPA and HPG axes and their interactions characterized by hair-based biomarkers

BACKGROUND

Past studies on schizophrenia (SCZ) and the stress-sensitive neuroendocrine systems have mostly focused on a single system and traditionally utilized acute biomarkers (e.g., biomarkers from blood, urine and saliva) that poorly match the chronic course of schizophrenia in time span. Using eight biomarkers in hair, this study aimed to explore the functional characteristics of SCZ patients in the hypothalamic-pituitary-adrenocortical (HPA) and hypothalamic-pituitary-gonadal (HPG) axes and the interaction between the two axes.

METHODS

Hair samples were taken from 137 SCZ patients and 73 controls. The SCZ patients were diagnosed by their attending physician according to the Diagnostic and Statistical Manual of Mental Disorders IV and were clinically stable after treatment. Gender, age, BMI, frequency of hair washing, marital status, education level, family history of mental illness and clozapine dosage were concurrently collected as covariates. The 10-item perceived stress scale (PSS-10) and the social readjustment rating scale were used to assess chronic stress status in SCZ patients. Eight hair biomarkers, cortisol, cortisone, dehydroepiandrosterone (DHEA), testosterone, progesterone, cortisol/cortisone, cortisol/DHEA and cortisol/testosterone, were measured by high performance liquid chromatography tandem mass spectrometer. Among them, cortisol, cortisone, DHEA and cortisol/DHEA reflected the functional activity of the HPA axis, and testosterone and progesterone reflected the functional activity of the HPG axis, and cortisol/cortisone reflected the activity of 11β-hydroxysteroid dehydrogenase types 2 (11β-HSD 2), and cortisol/testosterone reflected the HPA-HPG interaction.

RESULTS

SCZ patients showed significantly higher cortisone and cortisol/testosterone than controls (p<0.001, η²p=0.180 and p=0.015, η²p=0.031), lower testosterone (p=0.009, η²p=0.034), progesterone (p<0.001, η²p=0.069) and cortisol/cortisone (p=0.001, η²p=0.054). There were significant intergroup differences in male and female progesterone (p=0.003, η²p=0.088 and p=0.030, η²p=0.049) and female testosterone (p=0.028, η²p=0.051). In SCZ patients, cortisol, cortisol/cortisone, cortisol/DHEA and cortisol/testosterone were positively associated with PSS-10 score (ps<0.05, 0.212

CONCLUSION

The function of the HPA and HPG axes, the activity of 11β-HSD 2 and the HPA-HPG interaction were abnormal in SCZ patients. The abnormality of neuroendocrine systems was associated with chronic stress status in SCZ patients. This study provided evidence for abnormalities in the neuroendocrine systems in SCZ patients.

Current Findings and Potential Mechanisms of KarXT (Xanomeline-Trospium) in Schizophrenia Treatment

Standard schizophrenia treatment involves antipsychotic medications that target D2 dopamine receptors. However, these drugs have limitations in addressing all symptoms and can lead to adverse effects such as motor impairments, metabolic effects, sedation, sexual dysfunction, cognitive impairment, and tardive dyskinesia. Recently, KarXT has emerged as a novel drug for schizophrenia. KarXT combines xanomeline, a muscarinic receptor M1 and M4 agonist, with trospium, a nonselective antimuscarinic agent. Of note, xanomeline can readily cross blood-brain barrier (BBB) and, thus, enter into the brain, thereby stimulating muscarinic receptors (M1 and M4). By doing so, xanomeline has been shown to target negative symptoms and potentially improve positive symptoms. Trospium, on the other hand, is not able to cross BBB, thereby not affecting M1 and M4 receptors; instead, it acts as an antimuscarinic agent and, hence, diminishes peripheral activity of muscarinic receptors to minimize side effects probably stemming from xanomeline in other organs. Accordingly, ongoing clinical trials investigating KarXT's efficacy in schizophrenia have demonstrated positive outcomes, including significant improvements in the Positive and Negative Syndrome Scale (PANSS) total score and cognitive function compared with placebo. These findings emphasize the potential of KarXT as a promising treatment for schizophrenia, providing symptom relief while minimizing side effects associated with xanomeline monotherapy. Despite such promising evidence, further research is needed to confirm the efficacy, safety, and tolerability of KarXT in managing schizophrenia. This review article explores the current findings and potential mechanisms of KarXT in the treatment of schizophrenia.

COVID-19 coping experiences of individuals with schizophrenia: A grounded theory approach in Korea

Humankind has responded to the profound medical, economic, social, and cultural consequences of coronavirus disease 2019 (COVID-19) by employing various strategies. However, although individuals with mental disorders, including schizophrenia, have suffered more challenges from the infectious disease spread, they have received inadequate attention and care. Hence, this study aimed to explore the experiences of individuals with schizophrenia coping with COVID-19; one-to-one interviews were conducted with 17 individuals diagnosed with schizophrenia in Korea. The data were analysed using grounded theory methodology. The results showed that individuals with schizophrenia became distanced from the routine care they received before COVID-19, faced a dual threat from their mental illness and the emerging infectious disease, and experienced inequity and paradoxical situations. Nevertheless, they strived to live their daily lives by utilizing non-face-to-face access, seeking support from mental health professionals, and devising self-help measures. Moreover, reflecting on their lives throughout the pandemic after returning to their regular daily lives provided an opportunity for healing and growth. This study's results can provide evidence for treating individuals with schizophrenia and other mental disorders during subsequent infectious disease spread. Practical policies and interventions tailored to their vulnerabilities are required.

The Relationship Between Depression, Anxiety and Stress Levels on Suicidal Behavior in Patients with Schizophrenia

Background

Suicide is a major public health problem, and most people, who attempt suicide, have a psychiatric disorder. The preventable nature of suicide has further warranted the conduct of studies on suicide.

Methods

This cross-sectional and descriptive study aimed to investigate the effects of depression, anxiety, and stress levels on suicidal behavior in patients with schizophrenia. The study included 222 patients with schizophrenia. Data were collected by using the Descriptive Information Form, the Suicide Behaviors Questionnaire, and the Depression Anxiety Stress Scales-Short Form.

Results

It was found that 47.7% of the participants had suicidal ideation and 33.8% of them had attempted suicide by taking pills, self-cutting, jumping from a height, and hanging. While the participants had moderate levels of depression and anxiety, their stress levels were normal. The study has shown that the variables of stress, a good income level, and employment affect suicidal behavior, with a 1-unit increase in stress scores leading to an increase by 0.942, a 1-unit decrease in the good income level leading to an increase by 1.132, and a 1-unit increase in employment leading to an increase by 1.316 in suicidal behavior. Stress, income status, and employment accounted for 42.3% of the change in suicidal behavior.

Conclusion

This study has shown that suicidal ideation and suicide attempts are common in patients with schizophrenia compared to the normal population, and increased stress levels, poor income, and working in a job increased the risk of suicide among these patients. It can be suggested that efforts for improving stress management in patients during the post-pandemic period may be effective in reducing the risk of suicide.

Chronic corticosterone improves perseverative behavior in mice during sequential reversal learning

BACKGROUND

Stressful life events can both trigger development of psychiatric disorders and promote positive behavioral changes in response to adversities. The relationship between stress and cognitive flexibility is complex, and conflicting effects of stress manifest in both humans and laboratory animals.

OBJECTIVE

To mirror the clinical situation where stressful life events impair mental health or promote behavioral change, we examined the post-exposure effects of stress on cognitive flexibility in mice.

METHODS

We tested female C57BL/6JOlaHsd mice in the touchscreen-based sequential reversal learning test. Corticosterone (CORT) was used as a model of stress and was administered in the drinking water for two weeks before reversal learning. Control animals received drinking water without CORT. Behaviors in supplementary tests were included to exclude non-specific confounding effects of CORT and improve interpretation of the results.

RESULTS

CORT-treated mice were similar to controls on all touchscreen parameters before reversal. During the low accuracy phase of reversal learning, CORT reduced perseveration index, a measure of perseverative responding, but did not affect acquisition of the new reward contingency. This effect was not related to non-specific deficits in chamber activity. CORT increased anxiety-like behavior in the elevated zero maze test and repetitive digging in the marble burying test, reduced locomotor activity, but did not affect spontaneous alternation behavior.

CONCLUSION

CORT improved cognitive flexibility in the reversal learning test by extinguishing prepotent responses that were no longer rewarded, an effect possibly related to a stress-mediated increase in sensitivity to negative feedback that should be confirmed in a larger study.

Challenges faced when living with schizophrenia in the community: A narrative inquiry

BACKGROUND

Schizophrenia is a chronic and severe mental disorder. People with schizophrenia have transferred from hospital-based care to community-based care with the support of mental health legal policies. Challenges faced in the community should be emphasized. Limited qualitative studies have explored the challenges of living with schizophrenia.

AIMS

To explore the challenges of people living with schizophrenia in the community.

METHODS

A narrative method was used, including semi-structured, face-to-face interviews. Thematic analysis approach was used to analyze data.

RESULTS

Ten clients and their family members participated in the study. Analysis revealed three main themes related to their challenges in the community: deficits in self-management of illness; insufficient community mental health care; and the influence of policy. These challenges prevent those with schizophrenia from effectively managing their illness, returning to a productive role in society, and improving their quality of life.

CONCLUSIONS

There are challenges in mental health rehabilitation and social reintegration of individuals with schizophrenia. There is a need for continuous community mental rehabilitation services, appropriate policy support, and the need to educate the public to reduce social bias and discrimination which allows individuals with schizophrenia to assume a productive role in the community.

Levels of psychological capital among nurses: A systematic review and meta-analysis

AIM

To systematically evaluate the available literature about overall levels of psychological capital among nurses.

BACKGROUND

Psychological capital is described as a positive mental state associated with nurses' mental health, quality of care and patient outcomes.

METHODS

A search was carried out using PubMed, Web of Science, EMBASE, CINAHL, PsycINFO, Cochrane Library and Chinese Database, including China National Knowledge Infrastructure (CNKI), Chinese Biological Medical (CBM), WanFang and Weipu Database from the inception of the databases until October 2021. Subsequently, two researchers identified and reviewed the literature and assessed the risk of bias. A random-effects model was conducted to achieve pooled estimates of psychological capital scales.

RESULTS

The pooled mean score of the psychological capital scale was 4.21 (95% CI, 4.07-4.35). For subdimensions such as hope, optimism, self-efficacy and resilience, the score was 4.12 (95% CI, 4.11-4.12), 4.34 (95% CI, 4.34-4.34), 4.50 (95% CI, 4.50-4.51) and 4.34 (95% CI, 4.33-4.34), respectively. Subgroup analyses indicated that nurses practising in Asia and intensive care units might have experienced lower psychological capital levels. In addition, significant differences were noted in studies with sample size and publication year. Studies with a large sample size reported a higher psychological capital than those with a small sample size. The pooled mean scores of psychological capital were higher in 2014-2018 than in 2019-2021. Meta-regression further revealed that geographic regions of participants might be a source of heterogeneity, and the Asian region had 32.23% of the heterogeneity between studies, and the African region had 18.71%.

CONCLUSION

This review is the first to synthesize published research and calculate a pooled score of psychological capital in nurses. These findings indicated that nurses reported a medium-high level of psychological capital, and there was significant heterogeneity.

IMPLICATIONS FOR NURSING POLICY

Administrators and policymakers should concentrate on nurses' psychological capital and tactically integrate psychological capital into nursing vocational training programs.

Psychological Resilience May Be Related to Students' Responses to Victims of School Bullying: A Cross-Sectional Study of Chinese Grade 3-5 Primary School Students

BACKGROUND

School bullying is a major public health problem with a large impact on children's health. There is an increasing number of cases of school bullying reported in China. Studies have shown that the health consequences of different ways of responding to school bullying may be quite different and that psychological resilience is also closely related to aggressive behaviors. However, there has been little research on whether individuals with different psychological resilience levels respond differently.

OBJECTIVE

To explore the relationship between responses to school bullying and psychological resilience, which may provide new ideas and strategies to better prevent and intervene in school bullying.

METHODS

A random sample of 5425 primary school students aged 7-14 years were recruited in Luzhou, China. All students completed a questionnaire anonymously. The statistical significance of differences between groups was tested using the χ² test or t test. Binary logistic regression was conducted to explore the relationship between responses and psychological resilience.

RESULTS

Over two-thirds of primary school students in this study reported experiencing bullying in the past year. The rate of positive responses among victims was 69.10% (2596/3757, 95% CI: 67.62~70.58%). There was a positive relationship between psychological resilience and positive responses. This relationship was observed for all victims (OR = 1.605, 95% CI: 1.254~2.055), especially male victims (OR = 2.300, 95% CI: 1.624~3.259).

CONCLUSIONS

There was a positive relationship between primary school bullying responses and psychological resilience among victims, with differences by sex. Therefore, increasing students' level of psychological resilience, possibly by improving their responses, is important for preventing school bullying. Meanwhile, effective interventions for school bullying should be developed from multiple perspectives, particularly sex, bullying roles, and psychological resilience.

Relationship between job stress, thinking style and symptoms of post-traumatic stress disorder in mental health nurses

Introduction

Mental health nurses are often exposed to stressful events which may lead to feeling of stress in their daily work, and this feeling has a profound impact on nurses' mental health.

Aim

This study aimed to evaluate the relationship between job stress, thinking style and symptoms of post-traumatic stress disorder (PTSD) of mental health nurses, and to explore the mechanism of job stress and thinking style on symptoms of PTSD.

Method

This cross-sectional study collected related data of 351 mental health nurses in China, and the data was analyzed by PROCESS macro for SPSS.

Results

The results showed that 18.2% of mental health nurses had the symptoms of PTSD. Thinking style (monarchic thinking style, anarchic thinking style and external thinking style) played a moderating role in the predictive effects of job stress on the symptoms of PTSD.

Discussion

The research pointed out the relationship between job stress and symptom of PTSD, and clarified the critical role of thinking style among mental health nurses.

Implications for practice

It is recommended that organizations should enact effective policy and intervention programs to reduce job stress and PTSD symptoms of mental health nurses which may improve their mental health level.
