The Gaze of Schizophrenia Patients Captured by Bottom-up Saliency.

Schizophrenia (SCHZ) notably impacts various human perceptual modalities, including vision. Prior research has identified marked abnormalities in perceptual organization in SCHZ, predominantly attributed to deficits in bottom-up processing. Our study introduces a novel paradigm to differentiate the roles of top-down and bottom-up processes in visual perception in SCHZ. We analysed eye-tracking fixation ground truth maps from 28 SCHZ patients and 25 healthy controls (HC), comparing these with two mathematical models of visual saliency: one bottom-up, based on the physical attributes of images, and the other top-down, incorporating machine learning. While the bottom-up (GBVS) model revealed no significant overall differences between groups (beta = 0.01, p = 0.281, with a marginal increase in SCHZ patients), it did show enhanced performance by SCHZ patients with highly salient images. Conversely, the top-down (EML-Net) model indicated no general group difference (beta = -0.03, p = 0.206, lower in SCHZ patients) but highlighted significantly reduced performance in SCHZ patients for images depicting social interactions (beta = -0.06, p < 0.001). Over time, the disparity between the groups diminished for both models. The previously reported bottom-up bias in SCHZ patients was apparent only during the initial stages of visual exploration and corresponded with progressively shorter fixation durations in this group. Our research proposes an innovative approach to understanding early visual information processing in SCHZ patients, shedding light on the interplay between bottom-up perception and top-down cognition.

Pretreatment Cancer-Related Cognitive Impairment in Hodgkin Lymphoma Patients.

BACKGROUND: Cancer-related cognitive impairment (CRCI) is one of the most serious side effects of cancer that negatively impacts the quality of life of cancer patients and survivors. There is evidence of CRCI in Hodgkin lymphoma patients (HL); however, there is a lack of studies examining the presence of cognitive deficits before starting any treatment in HL patients. METHODS: Forty adult patients (N = 40) newly diagnosed with HL (with no previous cancer diagnoses) and 40 healthy controls (N = 40) matched for age, sex, education, and premorbid intellect completed the neuropsychological battery and subjective and objective measures of affective distress and quality of life. RESULTS: The results showed impairment in three out of six cognitive domains: verbal memory and learning, speed of processing/psychomotor speed, and abstraction/executive functions in the HL patients before the initiation of any treatment. The speed of processing/psychomotor speed domain is negatively correlated with depression. CONCLUSION: Cognitive deterioration in verbal memory and learning and abstraction/executive functions domains in HL patients seems to occur before the initiation of treatment independently of anxiety, depression, or physical symptoms. This suggests that HL itself may cause cognitive deficits in these cognitive domains. However, the underlying causes of CRCI still remain unclear.

An evaluation of the effect of equine-facilitated psychotherapy on patients with substance use disorders.

Equine Facilitated Psychiatry and Psychology (EFPP) is a supportive non-pharmacological treatment program used in the treatment of patients with substance use disorder. The aim of this study was to evaluate a possible change in patient's health and health-related quality of life between the first and fourth session of the EFPP program using the Assessment of Quality of Life (AQoL) and the Health of the Nation Outcome Scales (HoNOS). The Human-Animal Interaction Scale (HAIS) and a 5-point Likert-type scale was used for an assessment of patient's mood in the experimental group. The study sample included 57 patients (39 in experimental group with EFPP and 18 without EFPP program) with substance use disorders hospitalized in the psychiatric hospital. Comparing the initial and final patients scores in the experimental group, there was a significant positive shift in three of the four domains of the HoNOS scale and in seven of the eight dimensions of the AQoL scale. HAIS significantly increased (p <0.001) in time as well as patient´s mood after every session and in long time perspective. Based on these results, we can assume that the EFPP might be one of the successful programs which may improve patient´s mood and social interactions in substance use disorders.

Cognitive impairment associated with Hodgkin's lymphoma and chemotherapy.

Chemotherapy-related cognitive impairment (CRCI) is a well-documented side effect of cancer treatment in various types of tumors including Hodgkin's lymphoma (HL). However, a longitudinal study evaluating the cognitive performance of HL patients has been completely lacking. The aim of the study was to determine the presence of CRCI in HL patients before, promptly after, and 6 months after treatment. Thirty-six patients newly diagnosed with HL and 45 healthy controls (HC) completed the neuropsychological battery and psychological measures of affective distress and quality of life. The results indicate that HL patients have impaired performance compared to HC which cannot be explained by emotional factors. Cognitive impairments prior to treatment were found in 3 of 6 cognitive domains, i.e., verbal memory and learning, speed of processing/psychomotor speed, and abstraction/executive function. Promptly after the chemotherapy, deficits were found in the domains of memory and learning, verbal memory, speed of processing/psychomotor speed, and abstraction/executive function. Weaker cognitive performance persist even 6 months after the end of chemotherapy, specifically in domains of verbal memory and learning, and abstraction/executive function. Our results indicate the presence of cognitive impairment in HL patients already prior to treatment and increased damages caused by chemotherapy, while some of them may last for up to 6 months after the treatment.

Impact of a Long Lockdown on Mental Health and the Role of Media Use: Web-Based Survey Study.

BACKGROUND: Due to the COVID-19 pandemic, the Czech population experienced a second lockdown lasting for about half a year, restricting free movement and imposing social isolation. However, it is not known whether the impact of this long lockdown resulted in habituation to the adverse situation or in the traumatization of the Czech population, and whether the media and specific media use contributed to these effects. OBJECTIVE: The aim of this study was to elucidate the effect of the long lockdown on the mental health of the Czech population, and the role of exposure to COVID-19 news reports and specific forms of media news use in mental health. METHODS: We conducted two consecutive surveys in the early (November 2020) and late (March/April 2021) phases of the nationwide lockdown on the same nationally representative group of Czech adults (N=1777) participating in a longitudinal panel study. RESULTS: Our findings showed that the self-reported symptoms of anxiety and depression increased in the second observation period, confirming the negative effect of the pandemic lockdown as it unfolded, suggesting that restrictive measures and continuous exposure to a collective stressor did not result in the strengthening of resilience but rather in ongoing traumatization. The results also suggest a negative role of the media's coverage of the COVID-19 pandemic in mental health during the early, and particularly late, phases of the lockdown. Furthermore, we found several risk and protective factors of specific media news use. The media practice in news consumption connected to social media use was the strongest predictor of exacerbated mental health symptoms, particularly in the late phase of the lockdown. Moreover, news media use characterized by internalization of information learned from the news, as well as negative attitudes toward media news, were associated with higher levels of anxiety and depression. Conversely, the use of infotainment, together with an in-depth and contextual style of reading news articles, were related to improvement of mental health. CONCLUSIONS: Our study showed that the long lockdown resulted in traumatization rather than habituation, and in more pronounced effects (both negative and positive) of media use in mental health.

Posttraumatic Stress and Posttraumatic Growth in Three Generations of Czech and Slovak Holocaust Survivors.

The psychological consequences of trauma related to the Holocaust have been primarily studied in samples derived from Israel, North America, and Western Europe. Few studies have examined postcommunist countries in Central and Eastern Europe. The present study focused on three generations living in the Czech Republic and Slovakia after World War II (WWII): Holocaust survivors (71-95 years of age), their children (30-73 years of age), and their grandchildren (15-48 years of age). We compared scores on measures of posttraumatic stress symptoms (PTSS; the Posttraumatic Stress Disorder Checklist-Civilian Version) and posttraumatic growth (PTG; the Posttraumatic Growth Inventory) derived from three focal samples with scores from age-matched comparison participants. Higher PTSS scores emerged for Holocaust survivors in all generations, η2 P=.087 but only participants in the first generation reported higher PTG scores relative to the comparison group, with small effect sizes for the overall group differences, η2 P=.029 . These results are discussed in the historical and political context of postwar Czechoslovakia.

Validation of the Human-Animal Interaction Scale (HAIS) in Czech Language.

Human-Animal interaction (HAI) refers to any contact between humans and animals. Despite the lack of standardized measures of evaluation, one possible tool is the Human Animal Interaction Scale (HAIS). This study aimed to evaluate it in Czech language and to verify its use in clinical settings. One group of participants included 85 non-clinical volunteers; the second included 22 clinical participants, who were hospitalized in a long-term inpatient department All participants filled out the HAIS, the Companion Animal Bonding Scale (CABS) and the Companion Animal Semantic Differential (CASD). The Czech HAIS achieved similarly good psychometric properties as the original scale. The Cronbach's alpha showed strong internal consistency (α = 0.920) in the sample of volunteers, but low internal consistency (α = 0.656) in the group of clinical participants. In non-clinical volunteers, all scales and subscales correlated mutually at the p < 0.01 level. In the group of clinical participants, the CABS did not show significant correlations with other scales and subscales, nor was there a correlation of total HAIS score with the perceived rapport with animals. The findings of this study suggest that the Czech HAIS may be an effective tool for evaluating HAI with non-clinical contingents, however careful modification is suggested before clinical use. One reason for this is the difficulty in conducting some activities assessed by the scale in a clinical practice or hospital setting.

Deconstructing violence in acutely exacerbating psychotic patients.

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.
