RESUMO
Restrictions related to COVID-19 changed the daily behavior of people, including the expression of violence. Although an increased incidence of violent behavior, especially domestic violence, was expected during the pandemic, retrospective analyses have yielded mixed results. Records of ambulance departures to address injuries caused by assaults in the Pilsen region, Czech Republic, during the restrictive measures during the national state of emergency were compared to data from 3 previous years using general linear models. The number and severity of assaults were analyzed for the whole sample and separately for patients of either sex, for residential or nonresidential locations, and for domestic violence. Controlling for the seasonal effects, the number of assaults decreased by 39% during the pandemic restrictions compared to the 3 previous years. No difference was found between the effects of restrictions on assaults resulting in an injury of a male or female patient. The decrease was specifically pronounced in the sample of assaults in nonresidential locations, while no effect of restrictions was observed in assaults in residential locations and domestic assaults. Pandemic restrictions were associated with a decreased incidence of violent assaults that required ambulance services. Although the incidence decreased especially in those assaulted outside of their homes, we found no support for an increase in domestic violence or violence against women. Pandemic restrictions may have served as a protective rather than a risk factor for assaults severe enough to warrant a call for ambulance services.

OBJECTIVES: The primary aim was to test the hypothesis that physical interpersonal violence is decreased during the lockdown period in comparison with comparable control periods. The secondary aims were to explore the effects of gender and alcohol consumption on the violence during the lockdown. METHODS: Nationwide records of hospitalizations secondary to an assault were analyzed using quasipoisson regression. Assault rates in two lockdown periods, defined as a national emergency state, were compared to baseline data between 2017 and 2020, controlling for seasonal fluctuations and pandemic-related effects other than lockdown. To validate the findings on independent data, differences between lockdown and baseline in Police records of violent criminality between 2017 and 2021 were examined using one-way ANOVA. RESULTS: The rates of hospitalizations secondary to an assault decreased substantially during lockdowns (IRR = .43; P < .001) and the duration of lockdown did not affect assault rates (P = .07). The decrease in assault rates was more pronounced in males than females (IRR = .77; P < .05) and was weakened in patients with history of alcohol abuse (IRR = 1.83; P < .001). Violent crime rate decreased by 19% during the lockdowns compared to prepandemic baseline (P < .001). CONCLUSION: We found that physical interpersonal violence decreased during the COVID-19 lockdown periods. The reduction is significantly greater in males. Emerging evidence suggests an increased risk of alcohol use and intoxication during the lockdowns. Violent crime rate decreased during the lockdown.
RESUMO
Understanding the predictors of the willingness to get vaccinated against COVID-19 may aid in the resolution of current and future pandemics. We investigate how the readiness to believe conspiracy theories and the three dimensions of health locus of control (HLOC) affect the attitude toward vaccination. A cross-sectional study was conducted based on the data from an online survey of a sample of Czech university students (n = 866) collected in January 2021, using the multivariate linear regression models and moderation analysis. The results found that 60% of Czech students wanted to get vaccinated against COVID-19. In addition, 40% of the variance of willingness to get vaccinated was explained by the belief in the COVID-19-related conspiracy theories and the powerful others dimension of HLOC. One-sixth of the variance of the willingness to get vaccinated was explained by HLOC, cognitive reflection, and digital health literacy [eHealth Literacy Scale (EHEALS)]. HLOC and conspiracy mentality (CM) and its predictors are valid predictors of a hesitancy to get vaccinated against COVID-19. The campaigns promoting vaccination should target the groups specifically vulnerable to the conspiracy theories and lacking HLOC related to powerful others.
RESUMO
Negative symptoms in schizophrenia and schizoaffective disorder are present both in behavior and in the subjective experience of the patients, however the relationships between these two components have not been sufficiently studied. Standardized assessment methods were utilized in a study of 96 acutely exacerbated inpatients and 26 stabilized outpatients with the diagnosis of schizophrenia and schizoaffective disorder for the measurement of nega tive symptoms, subjective experiences, depression, general psychopathology and neurological side effects. Halo - peridol blood levels were controlled in the inpatient group. Results of this study suggest that the behavioral symptoms and the subjective experiences of the negative syndrome are not correlated with each other. The subjective experiences of negative symptoms were highly correlated with depression in the acutely exacerbated inpatients, but not in the outpatients. Medication levels and neurological side effects were not related either to the behavioral or the experiential aspects of the negative syndrome.

BACKGROUND: Victimization is associated with worse social and clinical outcomes of individuals with severe mental illness (SMI). A relapse of SMI may be one of the clinical consequences of assaultive trauma. As far as we know, there is no published study that analyzes nationwide health registers to assess the risk of SMI rehospitalization following assault. AIM: We aimed to assess whether exposure to assault is associated with an increased risk of psychiatric hospitalization in those with SMI. METHODS: We utilized data from the Czech nationwide registers of all-cause hospitalizations and all-cause deaths. We defined exposed individuals as those discharged from a hospitalization for SMI between 2002 and 2007, and hospitalized for serious injuries sustained in an assault in the subsequent 7 years. For each assaulted individual, we randomly selected five counterparts, matched on SMI diagnosis, age and sex, who were not assaulted in the examined time period. We used mixed effect logistic regression to assess the effect of assault on the risk of SMI rehospitalization within the following 6 months. We fitted unadjusted models and models adjusted for the number of previous SMI hospitalizations and drug use disorders. RESULTS: The sample consisted of 248 exposed and 1 240 unexposed individuals. In the unadjusted model, assaulted individuals were almost four times more likely to be rehospitalized than their non-assaulted counterparts (odds ratio (OR) = 3.96; 95% CI 2.75; 5.71). After adjusting for all covariates, the OR remained threefold higher (OR = 3.07; 95% CI 2.10; 4.49). CONCLUSION: People with a history of SMI hospitalization were approximately three times more likely to be rehospitalized for SMI within 6 months after an assault than their non-assaulted SMI counterparts. Soon after a person with SMI is physically assaulted, there should be a psychiatric evaluation and a close follow-up.
RESUMO
Understanding the predictors of belief in COVID-related conspiracy theories and willingness to get vaccinated against COVID-19 may aid the resolution of current and future pandemics. We investigate how psychological and cognitive characteristics influence general conspiracy mentality and COVID-related conspiracy theories. A cross-sectional study was conducted based on data from an online survey of a sample of Czech university students (n = 866) collected in January 2021, using multivariate linear regression and mediation analysis. Sixteen percent of respondents believed that COVID-19 is a hoax, and 17% believed that COVID-19 was intentionally created by humans. Seven percent of the variance of the hoax theory and 10% of the variance of the creation theory was explained by (in descending order of relevance) low cognitive reflection, low digital health literacy, high experience with dissociation and, to some extent, high bullshit receptivity. Belief in COVID-related conspiracy theories depended less on psychological and cognitive variables compared to conspiracy mentality (16% of the variance explained). The effect of digital health literacy on belief in COVID-related theories was moderated by cognitive reflection. Belief in conspiracy theories related to COVID-19 was influenced by experience with dissociation, cognitive reflection, digital health literacy and bullshit receptivity.

LEARNING OBJECTIVE: After participating in this activity, learners should be better able to:⢠Evaluate the anti-hostility effects of available atypical antipsychotic agents. ABSTRACT: In addition to hallucinations and delusions, persons with schizophrenia may exhibit hostility. In clinical trials of antipsychotics, hostility is routinely measured as part of rating scales such as the Brief Psychiatric Rating Scale or Positive and Negative Syndrome Scale. The availability of the atypical antipsychotic clozapine in 1989 led to the observation that it is possible to have a treatment effect on hostility that is independent of the treatment effect on hallucinations or delusions, and independent of general sedative effects. The data supporting this notion of a specific anti-hostility effect are the most robust for clozapine as the data include specifically designed randomized, controlled clinical trials. A specific anti-hostility effect is also observable to various degrees with most of the other atypical antipsychotics, as evidenced in post hoc analyses of clinical trials originally conducted for regulatory purposes, supplemented by post hoc analyses of large effectiveness trials. The generalizability of these studies, however, may be limited. Participants in these trials were not selected for aggressive and hostile behavior. Some of the studies also excluded patients with substance use disorders. The latter is particularly important because alcohol and substance use are well known to increase risk for hostility and aggression. Nevertheless, the repeated demonstrations of the specificity of an anti-hostility effect (in terms of statistical independence of effects on other positive symptoms and of sedation) are of potential clinical importance.

BACKGROUND: This study examined the proximate causes of psychotic patients' aggression upon the admission to the psychiatric wards of a university and two state hospitals. METHODS: The authors used a semistructured interview to elicit proximate causes of assaults from the assailants and victims. The treating psychiatrists and nurses provided additional information. Based on this interview, aggressive episodes were categorized as psychotic, impulsive and planned. RESULTS: A total of 820 assaults committed by 289 newly admitted violent psychotic inpatients were evaluated. The interview ratings indicated that 76.71% of the assaults were directly driven by psychotic symptoms and 22.32% of all attacks were labeled as impulsive. Only 0.98% of assaults were categorized as planned. CONCLUSIONS: These findings indicate that assaultive behavior among recently admitted acute psychiatric inpatients with untreated or undertreated psychosis is primarily driven by psychotic symptoms and disordered impulse control. Because each type of assault requires a different management, identifying the type of assault is crucial in determining treatment interventions.
RESUMO
PURPOSE: The principal aim is to review recent data concerning the very long-term outcome of schizophrenia and schizophrenia spectrum disorders. We examine factors that influence outcome, including therapeutic interventions. METHOD: PubMed and Scopus databases were searched for papers published between 2008 and 2017 reporting on prospective studies of schizophrenia or schizophrenia spectrum with a follow-up period ≥5 years with adequate outcome information. Additional publications were found in reference lists and authors' reference libraries. RESULTS: The average proportion of patients with symptomatic remission at follow-up ranged between 16.4% in never-treated patients to 37.5% in patients who were systematically treated with antipsychotics. Good outcomes at follow-up were observed in schizophrenia and schizophrenia spectrum patients on low doses of antipsychotics and in patients with no pharmacological treatment at that time. Early detection and intensive treatment of the first episode as well as the availability of continued psychosocial treatment and support over subsequent years appeared associated with better outcomes. CONCLUSION: The long-term outcome of schizophrenia is highly variable, depending on access to mental healthcare, early detection of psychosis and pharmacological treatment. Recent data support the effectiveness of low-dose antipsychotic treatment for long-term maintenance in some patients. A proportion of first-episode schizophrenia patients, perhaps 20%, do not need long-term maintenance antipsychotic treatment. That proportion may be higher in schizophrenia spectrum patients. The reasons why these patients do not need the long-term treatment are not well understood. Methods to predict the membership in this subgroup are not yet good enough for clinical use in individual patients.

Agitation and aggression in adult psychiatric patients with psychoses and in persons with dementia increase the burden of disease and frequently cause hospitalization. The implementation of currently available management strategies and the development of new ones is hindered by inconsistent terminology that confuses agitation with aggression. This confusion is maintained by many rating scales that fail to distinguish between these two syndromes. We review the frequently used rating scales with a particular focus on their ability to separate agitation from aggression. Agitation and aggression are two different syndromes. For example, reactive aggression is often precipitated by rejection of care and may not be associated with agitation per se. We propose, in treatment studies of behavioral symptoms of dementia and challenging behaviors in psychoses, that outcomes should be evaluated separately for agitation and aggression. This is important for investigation of drug effectiveness since the medication may be effective against one syndrome but not the other. Separate assessments of agitation and aggression should be a general principle of trial design with particular salience for registration studies of medications proposed for approval by the U.S. Food and Drug Administration and other regulatory bodies.

The Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) obtained a sample of 1493 chronic schizophrenia patients. The European First Episode Schizophrenia Trial (EUFEST) studied a sample of 498 patients. We have combined these two samples to study the predictors and correlates of adherence to treatment. Here we report on adherence to pharmacological treatment at the six and twelve month assessments of these trials with a combined subsample of 1154 schizophrenia patients. Individual patients׳ data were used for analyses. We used logistic regression to examine the effects of substance use, akathisia, parkinsonism, dyskinesia, hostility, and insight on pharmacological adherence. The results showed that reduced adherence to pharmacological treatment was associated with substance use (p=0.0003), higher levels of hostility (p=0.0002), and impaired insight (p<0.0001). Furthermore, poor adherence to study medication was associated with earlier discontinuation in the combined data. The clinical implications of the results point to the importance of routine assessments and interventions to address patients׳ insight and comorbid substance use and the establishment of therapeutic alliance.

Violent behavior associated with mental disorders is a common reason for admission to a psychiatric inpatient unit. Once hospitalized, patients may continue to be intermittently agitated and have persistent aggressive behaviors, preventing their discharge back into the community. Managing agitation quickly with effective pharmacological agents can avoid further escalation to aggression and violence. In the acute setting, this usually involves the parenteral use of antipsychotics, with or without benzodiazepines. Within the past decade, short-acting intramuscular formulations of second-generation antipsychotics have become available and provide a means to induce calm with a substantially lower risk of acute dystonia or akathisia compared with haloperidol. New alternative formulations that avoid injections include inhalation and sublingual administration. Longer-term management of persistent aggressive behavior by reducing the frequency and intensity of future episodes of agitation is more complex. In contrast to agitation associated with schizophrenia or bipolar mania, no agents have yet been approved by regulatory agencies for the treatment of persistent aggressive behavior. The strongest evidence supports the use of clozapine as an antihostility agent, followed by olanzapine. Adjunctive strategies with anticonvulsants and beta-adrenergic agents may also be worthwhile to consider.

Schizophrenia without any comorbidity confers a modest, but statistically significant elevation of the risk for violence. That risk is considerably increased by comorbid antisocial personality disorder or psychopathy as well as by comorbid substance use disorders. These comorbidities are frequent. Conduct disorder and conduct disorder symptoms elevate the risk for aggressive behavior in patients with schizophrenia. Violence among adults with schizophrenia may follow at least two distinct pathways-one associated with premorbid conditions, including antisocial conduct, and another associated with the acute psychopathology of schizophrenia. Aggressive behavior in bipolar disorder occurs mainly during manic episodes, but it remains elevated in euthymic patients in comparison with controls. The risk of violent behavior is increased by comorbidity with borderline personality disorder, antisocial personality disorder, and substance use disorders. These comorbidities are frequent. Borderline personality disorder and bipolar disorder are related in their phenomenology and response to medication. These two disorders share a tendency to impulsiveness, and impulsive behavior, including impulsive aggression, is particularly expressed when they co-occur.

INTRODUCTION: Aggressive behavior can be a dangerous complication of schizophrenia. Hostility is related to aggression. This study aimed to compare the effects of olanzapine, perphenazine, risperidone, quetiapine, and ziprasidone on hostility in schizophrenia. METHODS: We used the data that were acquired in the 18-month Phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study. We analyzed the scores of the Positive and Negative Syndrome Scale (PANSS) hostility item in a subset of 614 patients who showed at least minimal hostility (a score ≥ 2) at baseline. RESULTS: The primary analysis of hostility indicated an effect of difference between treatments (F(4,1487) = 7.78, P < 0.0001). Olanzapine was significantly superior to perphenazine and quetiapine at months 1, 3, 6, and 9. It was also significantly superior to ziprasidone at months 1, 3, and 6, and to risperidone at months 3 and 6. DISCUSSION: Our results are consistent with those of a similar post-hoc analysis of hostility in first-episode subjects with schizophrenia enrolled in the European First-Episode Schizophrenia Trial (EUFEST) trial, where olanzapine demonstrated advantages compared with haloperidol, quetiapine, and amisulpride. CONCLUSION: Olanzapine demonstrated advantages in terms of a specific antihostility effect over the other antipsychotics tested in Phase 1 of the CATIE trial.

BACKGROUND: Although most psychiatric patients are not violent, serious mental illness is associated with increased risk of violent behavior. Most of the evidence available pertains to schizophrenia and bipolar disorder. METHODS: MEDLINE data base was searched for articles published between 1966 and November 2012 using the combination of key words 'schizophrenia' or 'bipolar disorder' with 'aggression' or 'violence'. For the treatment searches, generic names were used in combination with key words 'schizophrenia' or 'bipolar disorder' and 'aggression' No language constraint was applied. Only articles dealing with adults were included. The lists of references were searched manually to find additional articles. RESULTS: There were statistically significant increases of risk of violence in schizophrenia and in bipolar disorder in comparison with general population. The evidence suggests that the risk of violence is greater in bipolar disorder than in schizophrenia. Most of the violence in bipolar disorder occurs during the manic phase. The risk of violence in schizophrenia and bipolar disorder is increased by comorbid substance use disorder. Violence among adults with schizophrenia may follow at least two distinct pathways-one associated with antisocial conduct, and another associated with the acute psychopathology of schizophrenia. Clozapine is the most effective treatment of aggressive behavior in schizophrenia. Emerging evidence suggests that olanzapine may be the second line of treatment. Treatment adherence is of key importance. Non-pharmacological methods of treatment of aggression in schizophrenia and bipolar disorder are increasingly important. Cognitive behavioral approaches appear to be effective in cases where pharmacotherapy alone does not suffice. CONCLUSIONS: Violent behavior of patients with schizophrenia and bipolar disorder is a public health problem. Pharmacological and non-pharmacological approaches should be used to treat not only violent behavior, but also contributing comorbidities such as substance abuse and personality disorders. Treatment adherence is very important for successful management of violent behavior.
