Affective predictors of social support in individuals with schizophrenia.

Background: Social Support has been found to contribute to lower mental illness burden, higher treatment adherence, enhanced social functioning, and better quality of life. Individuals with schizophrenia report lower social support compared to non-clinical populations, yet the factors contributing to this discrepancy are not fully clear. Specifically, the person-related variables that may enhance or hinder SS in people with schizophrenia are unknown.

Impact of Overall and Specific Dimensions of Schizotypy on Theory of Mind.

Background: Impairments in theory of mind (ToM) are highly prevalent among individuals with schizophrenia, resulting in substantial functional deficits. However, research on impairments in individuals with schizotypy has yielded inconsistent findings, with some studies finding ToM deficits in overall schizotypy, other studies finding ToM deficits in only specific schizotypy dimensions, and yet other studies finding no ToM deficits at all. One potential key factor that may account for this discrepancy is the use of schizotypy measures that do not adequately measure specific schizotypy dimensions.

Clinical, neurocognitive, neurobiological and functional correlates of sleep difficulties in individuals at-risk for psychosis and mania: A scoping review.

Sleep difficulties are highly prevalent among individuals with schizophrenia and bipolar disorder (BD), playing key roles in the onset, clinical presentation, and course of psychotic and manic episodes. However, less is known about sleep difficulties and their sequelae among individuals at-risk for psychosis and mania. Therefore, we conducted a scoping review of sleep disturbances among individuals at-risk for psychosis or mania.

Engagement of individuals with serious mental illness in outpatient mental health services and telehealth use during the COVID-19 pandemic.

Questions remain regarding whether the transition and continued use of telehealth was associated with changes in treatment engagement among patients with serious mental illness (SMI). Using NYS Medicaid claims, we identified 116,497 individuals with SMI receiving outpatient mental health services from September 1, 2019-February 28, 2021 and a comparison cohort of 101,995 from September 1, 2017-February 28, 2019 to account for unmeasured and seasonal variation. We characterized engagement in three 6-month increments (T-T-T) using clinically meaningful measures of high, partial, low, and none.

Psychiatric and affective predictors of negative racial attitudes.

Negative Racial Attitudes (NRA) have been identified as major contributors to discrimination and inequalities. Previous studies of predictors of NRA have focused largely on socioeconomic, socialization, social attitudes, and personality characteristics. Yet, the potential links of psychiatric and affective indicators to NRA have received little scientific inquiry.

Inflammation and emotion regulation: Findings from the MIDUS II study.

Emotion regulation (ER) strategies are thought to contribute to mental as well as physical health outcomes. Two common ER strategies include expressive suppression, or inhibition of emotional expression, and cognitive reappraisal, which involves changing how to think about an emotion-eliciting event in order to change its emotional impact. Recent reports have hypothesized that one potential way in which ER may be linked to health outcomes is via the immune system.

Exercise Intervention in Individuals at Clinical High Risk for Psychosis: Benefits to Fitness, Symptoms, Hippocampal Volumes, and Functional Connectivity.

Background And Hypothesis: Individuals at clinical high risk for psychosis (CHR-p) are less fit than nonclinical peers and show hippocampal abnormalities that relate to clinical symptoms. Exercise generates hippocampal neurogenesis that may ameliorate these hippocampal abnormalities and related cognitive/clinical symptoms. This study examines the impact of exercise on deficits in fitness, cognitive deficits, attenuated psychotic symptoms, hippocampal volumes, and hippocampal connectivity in individuals at CHR-p.

The Impact of Sleep on Neurocognition and Functioning in Schizophrenia-Is It Time to Wake-Up?

People with schizophrenia (SZ) display substantial neurocognitive deficits that have been implicated as major contributors to poor daily functioning and disability. Previous reports have identified a number of predictors of poor neurocognition in SZ including demographics, symptoms, and treatment adherence, as well as body mass index, aerobic fitness, and exercise activity. However, the putative impact of sleep has received relatively limited consideration, despite sleep disturbances, which are pervasive in this population, resulting in symptoms that are strikingly similar to the neurocognitive deficits commonly observed in SZ.

An integrative study of the microbiome gut-brain-axis and hippocampal inflammation in psychosis: Persistent effects from mode of birth.

Unlabelled: The mechanism producing psychosis appears to include hippocampal inflammation, which could be associated with the microbiome-gut-brain-axis (MGBS). To test this hypothesis we are conducting a multidisciplinary study, herein described. The procedures are illustrated with testing of a single subject and group level information on the impact of C-section birth are presented.

Psychosis risk individuals show poor fitness and discrepancies with objective and subjective measures.

Exercise is a promising intervention for individuals at clinical high-risk for psychosis (CHR). However, these youth may not be reliable reporters on fitness. There have been no investigations that utilized objective fitness assessment in this population.

Alexithymia, Affective Lability, Impulsivity, and Childhood Adversity in Borderline Personality Disorder.

Long-standing theories of borderline personality disorder (BPD) suggest that symptoms develop at least in part from childhood adversity. Emotion dysregulation may meaningfully mediate these effects. The current study examined three factors related to emotion dysregulation-alexithymia, affective lability, and impulsivity-as potential mediators of the relation between childhood adversity and BPD diagnosis in 101 individuals with BPD and 95 healthy controls.

Enhancement of aerobic fitness improves social functioning in individuals with schizophrenia.

Individuals with schizophrenia display substantial deficits in social functioning (SF), characterized by chronic, lifelong presentations. Yet, at present there are few effective interventions to enhance SF in this population. Emerging evidence from studies of clinical populations that display similar SF deficits suggests that aerobic exercise (AE) may improve social skills.

Combating the Dangers of Sedentary Activity on Child and Adolescent Mental Health During the Time of COVID-19.

Although the impact of the coronavirus disease 2019 (COVID-19) pandemic, subsequent quarantine, and social distancing on physical activity has been covered extensively, there has been limited focus on the resulting sedentary behavior on existing and emerging psychopathology. This is particularly disconcerting regarding children and adolescents, who rely on the ability to play to meet developmental milestones and who require more exercise than adults. Youth populations have been significantly disrupted by school closures and home confinement and are in developmental periods that overlap with the emergence of serious mental illness.

Considering the Microbiome in Stress-Related and Neurodevelopmental Trajectories to Schizophrenia.

Early life adversity and prenatal stress are consistently associated with an increased risk for schizophrenia, although the exact pathogenic mechanisms linking the exposures with the disease remain elusive. Our previous view of the HPA stress axis as an elegant but simple negative feedback loop, orchestrating adaptation to stressors among the hypothalamus, pituitary, and adrenal glands, needs to be updated. Research in the last two decades shows that important bidirectional signaling between the HPA axis and intestinal mucosa modulates brain function and neurochemistry, including effects on glucocorticoid hormones and brain-derived neurotrophic factor (BDNF).

The impact of emotion awareness and regulation on psychotic symptoms during daily functioning.

Emotion regulation (ER) difficulties are ubiquitous among individuals with schizophrenia and have been hypothesized to contribute to stress sensitivity and exacerbation of psychotic symptoms in this population. However, the evidence supporting this link is equivocal, potentially due to previous studies' reliance on retrospective assessments of ER and psychosis, as well as lack of consideration of putative moderators such as emotion awareness. To address these limitations, we employed experience sampling method using mobile electronic devices to investigate the links between momentary in vivo use of ER strategies (ER), emotion awareness, and psychotic symptoms during daily functioning.

Improving Cognition via Exercise (ICE): Study Protocol for a Multi-Site, Parallel-Group, Single-Blind, Randomized Clinical Trial Examining the Efficacy of Aerobic Exercise to Improve Neurocognition, Daily Functioning, and Biomarkers of Cognitive Change in Individuals with Schizophrenia.

Individuals with schizophrenia (SZ) display cognitive deficits that have been identified as major determinants of poor functioning and disability, representing a serious public health concern and an important target for interventions. At present, available treatments offer only minimal to moderate benefits to ameliorate cognitive deficits. Thus, there remains an urgent need to identify novel interventions to improve cognition in people with SZ.

Lexical analysis of emotional responses to "real-world" experiences in individuals with schizophrenia.

Abnormalities in emotion perception, expression, and experience are considered a core component of schizophrenia. Previous laboratory studies have demonstrated that while individuals with schizophrenia report levels of positive emotions comparable to healthy individuals in response to positive stimuli, they also report co-occurring negative emotions in response to such stimuli. However, it is unknown whether this response pattern extends to "real world" naturalistic environments.

The characteristics of cognitive neuroscience tests in a schizophrenia cognition clinical trial: Psychometric properties and correlations with standard measures.

In comparison to batteries of standard neuropsychological tests, cognitive neuroscience tests may offer a more specific assessment of discrete neurobiological processes that may be aberrant in schizophrenia. However, more information regarding psychometric properties and correlations with standard neuropsychological tests and functional measures is warranted to establish their validity as treatment outcome measures. The N-back and AX-Continuous Performance Task (AX-CPT) are two promising cognitive neuroscience tests designed to measure specific components of working memory and contextual processing respectively.
