RESUMO

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has had an impact on patients with substance use disorder (SUD). We aimed to investigate factors associated with confidence and adherence to governmental policies against COVID-19 (social desirability) among patients with SUD. Methods: This cross-sectional study was conducted during 2020 to 2021. Patients with SUD and healthy controls were recruited. The severity of sleep disturbance, social desirability, drug dependence, vaccine worries, other psychological burdens and demographic variables were collected through self-administrated questionnaires. Differences between the SUD and control groups were estimated. Hierarchical regression analysis was used to identify significant relationships between social desirability and other factors. Results: In total, 58 of patients with SUD and 47 healthy controls were recruited. The patients with SUD had a lower level of social desirability and more severe sleep disturbance than the control group. Older age, more severe sleep disturbance, lower level of drug dependence, and lower level of vaccine worries were significantly associated with a higher level of social desirability among the patients with SUD. Conclusion: Our results show the importance of timely interventions for drug dependence and to address vaccine worries in patients with SUD.

RESUMO

Biological disasters pose a growing challenge in the 21st century, significantly impacting global society. Taiwan has experienced such disasters, resulting in long-term consequences like loss of life, trauma, economic decline, and societal disruptions. Post-disaster, mental health issues such as fear, anxiety, depression, post-traumatic stress disorder (PTSD), and stress surge, accompanied by increased suicide rates. The Coronavirus disease 2019 (COVID-19) (also called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) pandemic, recognized as a biological disaster, triggered lockdowns and quarantines in Taiwan, causing lifestyle changes, economic recession, and so on. These shifts may elevate uncertainty about the future, intensifying mental stress and leading to a rise in various mental illnesses. This article reviews mental health studies conducted in Taiwan during the pandemic, emphasizing the need to integrate this research for future preparedness and interventions regarding the mental health impacts of biological disasters, including COVID-19. Further research is essential to explore long-term effects, interventions, and generalizability.

RESUMO

INTRODUCTION: The intention of chemsex-practicing gay and bisexual men and other men who have sex with men (GBMSM) to reduce their drug use is an important factor for the utilization of harm reduction services. This study aimed to examine data from an integrated sexual health services center to understand the relationship between the intention to reduce chemsex behavior and chemsex-related utilization of mental health services among GBMSM who engage in chemsex. METHOD: We used data collected from Healing, Empowerment, Recovery of Chemsex (HERO), an integrated health center in Taiwan, between November 2017 and December 2021. As the baseline, clients were asked to rate the current and ideal proportions of their sexual activities that involved the use of MDMA, ketamine, methamphetamine, GHB/GBL, or mephedrone. Having the intention to reduce chemsex was defined as having a lower proportion of ideal engagement compared to actual engagement. The data on the use of the services provided at HERO were linked to the survey responses and compared to information gathered during regular follow-up visits. Univariable and multivariable logistic regression analyses and a Poisson regression analysis were performed on the data. RESULTS: A total of 152 GBMSM reported engaging in chemsex, of whom 105 (69.1%) expressed the intention to reduce their chemsex behavior. Service utilization ranged from 23.0% for participating in meetings of a chemsex recovery group, 17.1% for visiting a mental health clinic, and 10.5% for using both of these services. The intention to reduce chemsex behavior significantly associated with visiting a mental health clinic (aOR = 4.68, p < 0.05), but its association with attending meetings of a chemsex recovery group was only marginally significant (aOR = 2.96, p < 0.1). Other factors that remained significantly associated with service use were a high frequency of substance use and living with HIV. CONCLUSION: Comprehensive harm reduction strategies, which touch on mental health, drug use management and recovery, are needed for those who want to reduce their chemsex behavior. Public health practitioners should endeavor to raise awareness of resources that are available for people who engage in chemsex and to minimize the barriers blocking their access to the appropriate services.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has caused a heavily burden on healthcare workers (HCWs) worldwide. The aim of this study was to compare differences in psychological and social impact between two waves of the pandemic among first- and second-line HCWs in Taiwan. The current study derived data from two cross-sectional surveys conducted in 2020 and 2021. Levels of depression, sleep disturbance, psychological distress, social impact, and demographic variables were collected through self-reported questionnaires. The independent t test was used to compare differences in scores between the first and second wave of the pandemic. Differences between first- and second-line HCWs were also analyzed. A total of 711 HCWs in the first wave and 560 HCWs in the second wave were recruited. For the first- and second-line HCWs, the social impact during the second wave was higher than during the first wave, and they expressed a higher intention to maintain social distancing and were more aware of the pandemic overseas in the second wave. The first-line HCWs had a trend of worse sleep quality during the second wave. In addition, sleep quality was worse in the first-line HCWs than in the second-line HCWs during both waves. The second-line HCWs expressed a greater desire to seek COVID-19-related information than the first-line HCWs during the first wave, and more intended to maintain social distancing during the second wave. Our results show the importance of evaluating the social and mental health burden of HCWs, and especially first-line workers.

RESUMO

Substance and alcohol use in the workplace have become a global health burden; however, the etiologies have seldom been explored. The aims of this study were to develop a Workplace Substance Reuse Questionnaire (WSRQ) to measure the multidimensional factors associated with the reuse of alcohol or illegal substances in the workplace. The predictors of reuse were also investigated. The WSRQs for alcohol (WSRQ-Alc) and illegal substances (WSRQ-Sub) were composed of 15 and 13 items, respectively. Factors associated with workplace substance reuse included workplace environment, workload, social interaction in the workplace and other cues. Construct validity and reliability were performed to verify the questionnaires. Multivariate linear regression was conducted to estimate the associations between the factors and WSRQ score. A total of 90 patients with substance or alcohol use disorder were recruited. The results demonstrated that the WSRQ-Alc and WSRQ-Sub had acceptable reliability, with variance of 76.4% and 75.4%, respectively. The confirmatory factor analysis fit indices also indicated the adequacy of the model. A longer duration of alcohol use (ß = 0.44; p = 0.002) and higher frequencies of changing job (ß = 0.32; p = 0.027) and working part time (ß = 0.32; p = 0.028) were significantly associated with higher WSRQ-Alc score. Our results highlight the importance of abstinence treatment and job referral for individuals with alcohol or substance use. Further studies are warranted to help extend the applicability and generalizability of the WSRQ.

RESUMO

Vaccine hesitancy has become a major public health problem among healthcare workers (HCWs) in this coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to examine the relationship between societal adaptation and vaccine worries and the mediating effects of posttraumatic stress disorder (PTSD) indicators in HCWs. A total of 435 HCWs (327 women and 108 men) were recruited. Their levels of societal adaptation were evaluated using the Societal Influences Survey Questionnaire (SISQ). Their severity and frequency of PTSD symptoms were examined using the Disaster-Related Psychological Screening Test (DRPST). The severity of vaccine worries was assessed using the Vaccination Attitudes Examination (VAX) Scale. The relationships among societal adaptation, PTSD, and vaccine worries were examined using structural equation modeling. The severity of societal adaptation was positively associated with both the severity of PTSD and the severity of vaccine worries. In addition, the severity of PTSD indicators was positively associated with the severity of vaccine worries. These results demonstrated that the severity of societal adaptation was related to the severity of vaccine worries, either directly or indirectly. The indirect relationship was mediated by the severity of PTSD. Societal adaptation and PTSD should be taken into consideration by the community of professionals working on vaccine hesitancy. Early detection and intervention of PTSD should be the objectives for programs aiming to lower vaccine hesitancy among HCWs.

RESUMO

OBJECTIVES: Schizophrenia is a serious mental illness. The serum protein biomarkers of schizophrenia were explored using isobaric tags for relative and absolute quantitation (iTRAQ) technology. The underlying function of the identified protein biomarker was also investigated. METHODS: We first collected serum samples from 12 schizophrenia patients and 12 healthy control (HC) subjects, followed by global screening with iTRAQ and tandem mass spectrometry (LC-MS/MS). In total, 691 serum proteins were detected and eight proteins, including ZYX, OSCAR, TPM4, SDPR, BST1, ARGHDB, ITIH5 and SH3BGRL3, were selected for further specific validation with enzyme-linked immunosorbent assay (ELISA) on the serum samples from 52 schizophrenia patients and 50 HC subjects. RESULTS: Schizophrenia patients had significantly lower serum level of BST1 and higher ITIH5 level than the HC subjects did. Using the levels of BST1, ITIH5 and OSCAR combined with machine learning algorithm, we developed a prediction model of schizophrenia with an auROC value 0.78. Moreover, in vitro cell assay confirmed that BST1 significantly repressed neutrophil infiltration through endothelial layer, highlighted the anti-inflammation nature of BST1. CONCLUSIONS: Four novel protein markers (BST1, ITIH5, SDPR, and OSCAR) of schizophrenia were identified, and BST-1 could serve as a serum protein biomarker involved in neutrophil infiltration in schizophrenia.

RESUMO

Background: The coronavirus infection disease 2019 (COVID-19) pandemic is likely to put healthcare professionals across the world in an unprecedented situation. Methods: A total of 683 healthcare workers were recruited in this study. Short form-12 items (SF-12), Societal Influences Survey Questionnaire (SISQ), and Disaster-Related Psychological Screening Test (DRPST) were used to survey participants. Multiple linear regression and structural equation model (SEM) were used to explore the possible factors to the societal influences and quality of life. Results: After multiple linear regression analysis, female, older, more education years, married, regular intake, and posttraumatic stress disorder (PTSD) frequency had positive association with SISQ. To physical component summary (PCS) of SF-12, chronic illness, sleep score, PTSD frequency, and social distance had negative association, and exercise habits had positive association. A mental component summary (MCS) value of SF-12, age, participate in social activities, and social information had positive association, and PTSD frequency, sleep score, social anxiety, and depression had negative association. Under SEM analysis, PTSD had positive influence on SISQ. Sleep score and MCS value had negative influences on SISQ. PTSD severity, older age, sleep score, smoking, and nursing staff had negative influences on PCS value. Young age, PTSD frequency, sleep score, and depression had negative influences on MCS value. Conclusion: Healthcare team members with severe PTSD symptoms suffered more societal influences. Relative to PTSD severity, PTSD frequency was more important to the quality of life. Members of older age who frequently participate in clubs, volunteers, or charity activities had better mental life quality.

RESUMO

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.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic can have a negative impact on patients with mood disorders. The aim of this study is to explore the societal influence of COVID-19 and associated impacts on levels of depression, sleep disturbance, and subjective pain among patients with mood disorders. This cross-sectional study recruited inpatients with depression and bipolar disorder. Levels of depression, sleep disturbance, subjective pain, and related demographic variables were collected through self-reported questionnaires. Potential factors associated with levels of depression, sleep disturbance, and subjective pain were identified using univariate linear regression and further entered into a stepwise multivariate linear regression model to identify the independent predictors. A total of 119 participants were included in the analysis, of whom 50.42% had bipolar disorder and 49.58% had unipolar depression. Multivariate analysis showed that a higher level of depression was associated with female subjects, subjects with partners, present history of psychological trauma, and drinking alcohol. Sleep disturbance was associated with subjects with partners and drinking alcohol. A higher level of subjective pain was associated with a higher level of social anxiety and a history of psychological trauma. The current study identified several predictors of psychological burden and subjective pain among inpatients with depression during the COVID-19 pandemic. Further investigations are warranted to extend the application and generalizability of our results.

RESUMO

BACKGROUND: The experiences of professionals in well-established recovery-oriented programs are valuable for professionals in similar practice settings. This study explored professionals' experiences with providing recovery-oriented services in community psychiatric rehabilitation organizations. METHODS: Semi-structured interviews were conducted with 14 professionals from five recovery-oriented psychiatric rehabilitation organizations in Taiwan. The interviews were recorded and transcribed verbatim. Thematic analysis was used for the qualitative data analysis. RESULTS: The analyses documented three main themes with 13 subthemes. Recovery-oriented service implementation included seven subthemes: Enabling clients to set their own goals and make decisions, using a strengths-based approach, establishing partnerships with clients, improving individuals' self-acceptance, encouraging community participation, seeking family, peer, and organizational support, and building team collaboration. Problems with implementing recovery-oriented services included limited policy and organizational support, a lack of understanding of recovery among professionals, stigma, clients' lack of motivation or self-confidence in their own ability to achieve recovery, and passive or overprotective family members. Strategies to resolve implementation problems included policy changes and organizational support, improving the recovery competence and confidence of professionals, and family and public education. CONCLUSIONS: To date, this is the first known study examining the perspectives of mental health professionals who have experience implementing recovery-oriented services in Asia. The participants identified family collaboration, anti-stigma efforts, and changes in policy and attitudes as critical to successful implementation and delivery of recovery-oriented services.

RESUMO

Cognitive deficits, which are core manifestations in schizophrenia and exhibit a limited response to antipsychotic treatment, contribute to poor treatment outcomes and functional disability. Evidence on the effect of aerobic walking (AW) and exercise intensity on cognitive function in patients with schizophrenia is lacking. In total, 79 patients with schizophrenia were recruited for a 12-week randomized control trial and allocated to the treatment-as-usual (TAU, n = 38) and treatment-as-usual plus AW (TAW, n = 39) groups. The TAW participants joined a supervised 12-week AW program consisting of 30-min sessions five times per week while wearing a Fitbit Charge 2 device. Cognitive function was evaluated using the Brief Assessment of Cognition in Schizophrenia. After randomization, 67 (34 TAU and 33 TAW) participants joined the 12-week trial and were included in the intention-to-treat analysis. Multivariate general linear model repeated measures analysis revealed no significant time × group interaction effect on cognitive function changes between the TAU and TAW groups and a marginally significant group effect on verbal fluency (p = 0.09). The interaction effect of time and treatment group on verbal fluency (p = 0.05) was marginally significant between the high and low AW intensity groups, whereas a significant group effect on attention and processing speed (p = 0.04) was observed. Supervised 12-week AW of moderate intensity may have potential cognitive benefits for patients with schizophrenia.

RESUMO

BACKGROUND: The outbreak of coronavirus disease 2019 (COVID-19), like severe acute respiratory syndrome (SARS), provokes fear, anxiety and depression in the public, which further affects mental health issues. Taiwan has used their experience of the SARS epidemic for the management of foreseeable problems in COVID-19 endemic. AIM/OBJECTIVE: This review summarizes issues concerning mental health problems related to infectious diseases from current literatures. RESULTS: In suspected cases under quarantine, confirmed cases in isolation and their families, health care professionals, and the general population and related effective strategies to reduce these mental health issues, such as helping to identify stressors and normalizing their impact at all levels of response as well as public information and communication messages by electronic devices. The importance of community resilience was also addressed. Psychological first aid, psychological debriefing, mental health intervention and psychoeducation were also discussed. Issues concerning cultures and religions are also emphasized in the management plans. CONCLUSION: Biological disaster like SARS and COVID-19 not only has strong impact on mental health in those being infected and their family, friends, and coworkers, but also affect wellbeing in general public. There are evidenced that clear and timely psychoeducation, psychological first aid and psychological debriefing could amileorate negative impact of disaster, thus might also be helpful amid COVID-19 pandemic.

RESUMO

Psychiatric hospitals play an important role in supporting patients with mental illness to relieve symptoms and improve functioning in a physically and psychologically safe environment. However, these hospitals are also vulnerable to emerging infectious diseases. In early 2020, a psychiatric hospital and a psychiatric unit were reported to have nosocomial coronavirus disease 2019 (COVID-19) infection. A large number of patients and staff were severely impacted. This type of nosocomial infection threatens patient safety and quality of care. By learning from previous experiences of severe acute respiratory syndrome (SARS) and previous studies, psychiatric hospitals can provide safeguards to prevent nosocomial infection among patients and staff during an epidemic or biological disaster. These strategies include a series of actions such as following national guidelines for infection control, reserving adequate support for disinfection equipment, providing relevant and sufficient pro-service and in-service education and training, establishing regular surveillance of hand hygiene habits, proper communication and health education, and providing opportunities for vaccination if possible. Based on the harm reduction concept, staff division of office breaks and ward classification and shunting are recommended and should be further implemented.

RESUMO

Pre-exposure prophylaxis (PrEP) has proven to be effective in reducing the risk of HIV transmission in uninfected individuals who engaged in sexual activity with HIV-infected partners. Serodiscordant couples are the key targets of PrEP implementation. The study aimed to compare awareness of and willingness to use PrEP and anticipated condom use among 112 HIV-serodiscordant couples: 32 heterosexuals couples, 70 men who have sex with men (MSM) couples, and 10 people who inject drugs (PWID) couples. A cross-sectional study was conducted in an AIDS designated hospital in Taiwan. The PrEP survey for discordant couples included questions on awareness of non-occupational post-exposure prophylaxis (nPEP) and PrEP, attitudes toward PrEP, anticipated condom use if using PrEP, and sexual behaviors. Overall, 46.2% were aware of PrEP, only 33% were willing to take PrEP, and 44.6% would continue condom use if they were taking PrEP. Among the three key populations, MSM couples had the highest awareness of and willingness to use PrEP. Awareness of and willingness to use PrEP did not differ by HIV status, with moderate agreement (Cohen's Kappa coefficient: 0.56) between HIV-serodiscordant partners. Both HIV-serodiscordant partners' willingness to use PrEP was significantly associated with being MSM (adjusted odds ratio (AOR), 4.28 [1.28-14.30], p = 0.018), previous receipt of nPEP (AOR, 6.98 [1.23-39.65], p = 0.028), anticipated condom use (AOR, 0.14 [0.05-0.41], p < 0.001), and income ≥ NT$30,000 per month (AOR, 2.25 (0.99-5.04), p = 0.05). Policy makers need to consider the differences among key populations to scale up PrEP implementation. More efforts should be focused on improving awareness of and willingness to use PrEP among heterosexual and PWID serodiscordant couples to scale up PrEP implementation in Taiwan.

RESUMO

BACKGROUND: ß-hydroxybutyrate (ß-HB) and pyruvate have been associated with the brain energy utilization, which may play a role in the pathophysiology of schizophrenia. In this prospective study, we aim to investigate the trends of ß-HB and pyruvate levels, metabolic changes, and cognitive function in schizophrenia patients receiving antipsychotic treatment. OBJECTIVE: We recruited 38 schizophrenia patients who had been treated with antipsychotics for 12 weeks, as well as 38 healthy age- and gender-matched subjects. Blood samples were taken from the patients at baseline and week 12 to determine the serum levels of ß-HB, pyruvate, and metabolic parameters, while blood samples of the healthy controls were taken at baseline. We evaluated the psychopathology using the Positive and Negative Syndrome Scale and cognitive function using the Brief Assessment of Cognition in Schizophrenia. RESULTS: During the 12-week follow-up period, the ß-HB levels in patients with schizophrenia showed a decreasing trend, particularly in those undergoing treatment with aripiprazole or ziprasidone. The serum levels of ß-HB in patients at baseline and week 12 were both higher than the levels in the healthy controls. Among the schizophrenia patients, changes in ß-HB were positively correlated with changes in executive function. On the other hand, serum pyruvate levels remained steady during the 12-week follow-up period, and we found no significant correlation between pyruvate changes and changes in cognitive function or clinical symptoms. CONCLUSION: Our findings indicate that ß-HB may possess a potential indicator of energy utilization and have a protective role in executive function in patients with schizophrenia. Additional longitudinal studies with a larger sample size and longer follow-up periods are necessary to identify the relationship of metabolite regulation and cognitive function during schizophrenia patients' exposure to antipsychotics.

RESUMO

BACKGROUND: Oxidative stress has been implicated in the psychopathology of schizophrenia. Cysteine, a semi-essential amino acid, is the precursor of the antioxidant glutathione. The aim of this study was to investigate the differences in serum levels of cysteine between patients with schizophrenia and healthy controls. The relationships between levels of cysteine, psychopathology and cognitive function were also explored. METHODS: We recruited 65 patients with schizophrenia and 65 age- and gender-matched healthy controls. Blood samples were collected to determine the serum levels of cysteine and plasma levels of metabolic parameters. The cognitive function of participants was assessed using the Brief Assessment of Cognition in Schizophrenia (BACS). The psychopathology of schizophrenic patients was evaluated using the Positive and Negative Syndrome Scale. RESULTS: Serum cysteine levels were significantly higher in schizophrenic patients than in controls (P<0.001). In patients with schizophrenia, serum levels of cysteine were positively correlated with cognitive function in terms of verbal memory (P=0.013), working memory (P=0.004), verbal fluency (P=0.027), attention and processing speed (P=0.025), executive function (P=0.024) and the composite score on the BACS (P=0.013). In healthy controls, no significant correlation was observed between cysteine level and cognitive function. CONCLUSIONS: These findings suggest that oxidative stress may be involved in the pathogenesis of schizophrenia, and compensatory elevated levels of cysteine may serve as an indicator of cognition preservation. Further prospective studies are warranted to investigate the dynamic alterations in cysteine and the underlying pathophysiology of schizophrenia.
