Empathic accuracy in individuals with schizotypal personality traits.

Empirical research using the Empathic Accuracy Task (EAT) has suggested that schizophrenia patients and people with schizotypal personality disorder exhibit lower empathic accuracy than healthy people. However, empathic accuracy in a subclinical sample with high levels of schizotypy has seldom been studied. Our study aimed to investigate empathy in a subclinical sample using the Chinese version of the EAT and a self-report empathy measure.

A meta-analysis of the association between mindfulness and motivation.

Introduction: Mindfulness reflects attention to the present moment in a non-judgmental way and has been linked to individual autonomy and motivation, but conclusions are inconsistent. The purpose of this review was to summarize previous studies to explore the relationship between mindfulness and motivation and its intervention effects.

Methods: Literature searches were conducted in five electronic databases.

Relationships between childhood trauma and dimensional schizotypy: A network analysis and replication.

Objectives: Childhood trauma (CT) has been found to increase the risk of developing schizophrenia and other psychiatric disorders. Little is known regarding the complex interplay between CT, subclinical psychotic, and affective symptoms in the general population. This cross-sectional study adopted network analysis to examine such a complex relationship.

Comparisons of facial emotion recognition in different social contexts among patients with schizophrenia, major depressive disorder and bipolar disorder.

Background: Previous studies have found that patients with schizophrenia (SCZ), major depressive disorder (MDD), and bipolar disorder (BD) all have facial emotion recognition deficits, but the differences and similarities of these deficits in the three groups of patients under different social interaction situations are not clear. The present study aims to compare the ability of facial emotion recognition in three different conversation situations from a cross-diagnostic perspective.

Methods: Thirty-three participants with SCZ, 35 participants with MDD, and 30 participants with BD were recruited, along with 31 healthy controls.

The association of glutamate level in pregenual anterior cingulate, anhedonia, and emotion-behavior decoupling in patients with major depressive disorder.

Impairments of translating emotional salience into effortful behavior are core features of anhedonia in cohorts with major depressive disorder. Glutamate metabolism is considered to be involved in this process, but the empirical study is relatively few. Therefore, the present study aimed to examine the correlations between glutamate level in pregenual anterior cingulate, anhedonia, and emotion-behavior decoupling in patients with major depressive disorder.

Novel cellular therapies for hepatobiliary malignancies.

Background: The mortalities of hepatobiliary malignancies are high. With the failure of conventional chemotherapy and unsatisfactory outcome of molecular targeted drugs, immune-based therapy has become a new focus of research in hepatobiliary cancers treatment.

Data Sources: We performed a PubMed search with relevant articles published up to May 2022 and the following keywords: cellular immunotherapy, hepatobiliary cancer, antigen receptor T cell therapy, and receptor-engineered T cell.

Altered empathy correlates with reduced social and non-social reward anticipation in individuals with high social anhedonia.

This study examined the correlations of affective and cognitive components of empathy with reward anticipation toward monetary and social incentives in individuals with social anhedonia (SocAnh). According to the scores on the Revised Social Anhedonia Scale, 109 participants were divided into high (n = 57) and low (n = 52) SocAnh groups. Empathy was assessed with the Questionnaire of Cognitive and Affective Empathy (QCAE) and the Interpersonal Reactivity Index (IRI) Scale.

Impairment of response inhibition to emotional face stimuli in individuals with subclinical depression.

Response inhibition, a crucial component of executive function, is closely related to personal impulse control, social adaption, and mental health. Previous studies have found response inhibition deficit in patients with major depressive disorder, but whether it also exists in individuals with subclinical depression (SD) remains unclear. This study aimed to identify the ability of response inhibition to emotional face stimuli both under explicit and implicit conditions in individuals with SD.

Shared and distinct reward neural mechanisms among patients with schizophrenia, major depressive disorder, and bipolar disorder: an effort-based functional imaging study.

Unwillingness to exert effort for rewards has been found in patients with schizophrenia (SCZ), major depressive disorder (MDD), and bipolar disorder (BD), but the underlying shared and distinct reward neural mechanisms remain unclear. This study aimed to compare the neural correlates of such impairments across different diagnoses. The neural responses in an effort-expenditure for reward task (EEfRT) were assessed in 20 SCZ patients, 23 MDD patients, 17 BD patients, and 30 healthy controls (HC).

Individuals with Autistic Traits Exhibit Heightened Alexithymia But Intact Interoceptive-Exteroceptive Sensory Integration.

Interoceptive accuracy has been widely measured using the Heartbeat Tracking Test (HTT). We devised the novel paradigm of Interoception-Exteroception Synchronicity Judgement (IESJ) task to assess participants' interoceptive accuracy, exteroceptive accuracy, and the balancing score which reflected the ability to allocate attentions between interoceptive and exteroceptive signals. This study administered the behavioural paradigms of the HTT and the IESJ as well as other self-report scales to 119 typically-developing youths.

Validation of the Questionnaire of Cognitive and Affective Empathy in patients with schizophrenia, major depressive disorder and bipolar disorder.

Introduction: Alteration of empathy is common in patients with psychiatric disorders. Reliable and valid assessment tools for measuring empathy of clinical samples is needed. The Questionnaire of Cognitive and Affective Empathy (QCAE) is a newly-developed instrument to capture cognitive and affective components of empathy.

Altered default mode network functional connectivity in individuals with co-occurrence of schizotypy and obsessive-compulsive traits.

In this study, we examined differences in resting-state functional connectivity between sub-regions of the Default Mode Network (DMN) and whole brain voxels in 22 individuals with high schizo-obsessive traits (SOT), 30 with high schizotypal traits (SCT) alone, 20 with high obsessive-compulsive traits (OCT) alone and 30 with low trait scores (LT). We found that the SOT group showed the most reduced functional connectivity within the DMN compared with the other groups. The SOT group also showed increased connectivity between the DMN and the Salience Network, and between the DMN and the Auditory Network compared with the LT group.

Altered brain structural and functional connectivity in schizotypy.

Background: Schizotypy refers to schizophrenia-like traits below the clinical threshold in the general population. The pathological development of schizophrenia has been postulated to evolve from the initial coexistence of 'brain disconnection' and 'brain connectivity compensation' to 'brain connectivity decompensation'.

Methods: In this study, we examined the brain connectivity changes associated with schizotypy by combining brain white matter structural connectivity, static and dynamic functional connectivity analysis of diffusion tensor imaging data and resting-state functional magnetic resonance imaging data.

A transdiagnostic comparison of affective decision-making in patients with schizophrenia, major depressive disorder, or bipolar disorder.

Deficit in decision-making has been found in patients with schizophrenia (SCZ), major depressive disorder (MDD), and bipolar disorder (BD), respectively, while the common and distinct characteristics of this deficit among these patients are still unclear. The present study aimed to make a transdiagnostic comparison of the affective decision-making ability in patients with SCZ, MDD, and BD. In this study, 33 patients with SCZ, 23 patients with MDD, 29 patients with BD, and 34 healthy controls (HCs) were recruited and the Iowa Gambling Task (IGT) was used to assess the affective decision-making ability.

Emotion-behavior decoupling in individuals with schizophrenia, bipolar disorder, and major depressive disorder.

Failure in translating emotional salience into effortful behavior is thought to be a core feature of anhedonia and avolition in individuals with schizophrenia (SCZ), but little is known about emotion-behavior coupling in individuals with bipolar disorder (BD) and major depressive disorder (MDD). In this study, we compared emotion-behavior correspondence in participants with SCZ, BD, and MDD. Forty-two participants with SCZ, 44 participants with MDD, 43 participants with BD, and 43 healthy controls were recruited.
