Poor sleep quality has been repeatedly linked to the entire psychosis continuum, including psychotic-like experiences (PLEs); however, sleep dysfunction is a component of several other psychopathologies that have also been linked to increased risk for PLEs, including depression, anxiety, and post-traumatic stress disorder (PTSD). It has yet to be examined if PLEs are a significant risk factor for poor sleep quality or if this sleep dysfunction is better accounted for by comorbid psychopathology. In 2687 undergraduates, PLEs were evaluated using the positive items of the Prodromal Questionnaire...

BACKGROUND: The 22q11.2 deletion syndrome (22q11DS) is the most common genetic syndrome associated with schizophrenia. The goal of this study was to evaluate longitudinally the interaction between neurocognitive functioning, the presence of subthreshold psychotic symptoms (SPS) and conversion to psychosis in individuals with 22q11DS. In addition, we attempted to identify the specific neurocognitive domains that predict the longitudinal evolution of positive and negative SPS, as well as the effect of psychiatric medications on 22q11DS psychiatric and cognitive developmental trajectories...

Activated microglia express the translocator protein (TSPO) on the outer mitochondrial membrane. 18F-PBR111 is a second-generation positron emission tomography (PET) ligand that specifically binds the TSPO, allowing in-vivo visualization and quantification of neuroinflammation. The aim of this study is to evaluate if the test-retest variability of 18F-PBR111 in healthy controls is acceptable to detect a psychosis-associated neuroinflammatory signal in schizophrenia. Methods: Dynamic 90-min 18F-PBR111 scans were obtained in 17 healthy male controls (HC) and 11 male schizophrenia patients during a psychotic episode (SP)...

BACKGROUND: The stigma of psychosis, with the accompanying symptoms of auditory and visual hallucinations, can affect a nurse's ability to provide safe, effective care. Increasing knowledge of the patient's perspective during auditory hallucinations can increase the nurse's ability to be empathetic and engage in a therapeutic alliance. OBJECTIVE: To evaluate the efficacy of a six-second auditory hallucination simulation to increase empathy in preclinical undergraduate nursing students...

AIMS: Improving diagnostic batteries to identify individuals at-risk for developing psychotic disorders as early as possible is an ongoing challenge in schizophrenia research. Here, we sought to explore whether metacognition in at-risk of developing psychosis would differ from that of first episode psychosis and unaffected controls and whether dysfunctional metacognitive beliefs would be associated with psychosocial functioning in the clinical groups. METHODS: Twenty-three subjects at-risk of psychosis were compared with a group of 15 first psychotic episode patients and 21 healthy controls with regard to their metacognitive beliefs and psychosocial functioning...

BACKGROUND: Although it has been shown that anxiety and depression are associated with increased complications after total joint arthroplasty (TJA), the outcomes of TJA in patients with a history of psychosis are unknown. This study evaluated the influence of bipolar and schizophrenic disorders on complications after TJA, particularly aseptic and septic revisions. METHODS: A retrospective review of 156 TJAs (125 primaries and 31 revisions) was performed at a single institution from 2000 to 2015...

Several studies have indicated infectious and immune-related abnormalities in schizophrenia (Scz), including elevated serum C-reactive protein (CRP) - a well-known proxy for infections/immune abnormalities. A portion of the genetic risk for Scz can be estimated using the polygenic risk score (PGRS). It is not known whether there is an interaction in the risks traceable to CRP and PGRS. Patients with Scz and individuals without psychosis were evaluated systematically using DSM IV criteria (N=794, N=446, respectively)...

Parkinson's disease (PD) is a neurodegenerative disorder characterized by progressive loss of dopaminergic neurons in the substantia nigra of the human brain, leading to depletion of dopamine production. Dopamine replacement therapy remains the mainstay for attenuation of PD symptoms. Nonetheless, the potential benefit of current pharmacotherapies is mostly limited by adverse side effects, such as drug-induced dyskinesia, motor fluctuations and psychosis. Non-dopaminergic receptors, such as human A2A adenosine receptors, have emerged as important therapeutic targets in potentiating therapeutic effects and reducing the unwanted side effects...

Impairments in social cognition are key determinants of poor functioning in psychosis and an important new target for treatment development. Initial studies support the feasibility and efficacy of training interventions for social cognition, but have been small and have had substantial methodological limitations. This report describes the largest rigorously controlled study of a social cognitive treatment to date. We evaluated the efficacy of a refined version of the 24-session Social Cognitive Skills Training (SCST) program, and whether adding in vivo training sessions in community settings would enhance generalization to functional improvements...

Objective Numerous studies on the effects of seclusion and/or restraint in acute psychiatric treatment have reported both positive and negative effects. However, no studies to date have evaluated the effects of seclusion and/or restraint on schizophrenia patients using a rating scale. Thus, to examine the effects of seclusion and/or restraint on schizophrenia patients, we used the Brief Psychiatric Rating Scale and assessed the psychological condition of patients. Methods Factor analysis was conducted to create subscales of Brief Psychiatric Rating Scale, and psychiatric changes were assessed with respect to each subscale using multiple logistic regression analyses...

BACKGROUND: There is mounting evidence that people with severe mental illness have unhealthy lifestyles, high rates of cardiovascular and metabolic diseases, and greater risk of early mortality. This study aimed to assess the cost-effectiveness of a health promotion intervention seeking to improve physical health and reduce substance use in people with psychosis. METHODS: Participants with a psychotic disorder, aged 18-65 years old and registered on an enhanced care approach programme or equivalent were recruited from community mental health teams in six mental health trusts in England...

OBJECTIVE: Smoking rates in adolescents at risk of psychosis are significantly greater than those who are not at risk. Recent research suggests that cigarette smoking in adolescence may be a potential marker of transition to psychosis, although the exact relationship between the two remains unclear. Our aim was to examine whether tobacco smoking is a potential marker of transition to psychosis or subsequent episodes of psychosis, independently of other substance use, or alternatively, if smoking is essentially a general marker of later mental illness episodes...

Postpartum psychosis (PP) is the most severe psychiatric disorder associated with childbirth. The risk of PP is very high in women with a history of bipolar affective disorder or schizoaffective disorder. However, the neurobiological basis of PP remains poorly understood and no study has evaluated brain structure in women at risk of, or with, PP. We performed a cross-sectional study of 256 women at risk of PP and 21 healthy controls (HC) in the same postpartum period. Among women at risk, 11 who developed a recent episode of PP (PPE) (n = 2 with lifetime bipolar disorder; n = 9 psychotic disorder not otherwise specified) and 15 at risk women who did not develop an episode of PP (NPPE) (n = 10 with lifetime bipolar disorder; n = 1 with schizoaffective disorder; n = 1 with a history of PP in first-degree family member; n = 3 with previous PP)...

OBJECTIVE: Despite a theoretical consensus that interictal psychosis (IIP) is related to various epilepsy-related factors, the impact of seizure activity on development of IIP remains inconclusive. This is the first controlled study using quantitative seizure-activity measures at the onset of IIP. METHODS: One hundred and eighty-one patients with epilepsy who exhibited first-episode IIP (IIP group) and 427 patients with epilepsy without psychotic episodes (control group) were enrolled...

BACKGROUND: Previous studies have suggested that, despite marked functional impairments, remitted first episode patients with schizophrenia report levels of well-being that are comparable to healthy controls. The aim of the current study was to specifically evaluate self-reported happiness, life satisfaction and success in individuals with schizophrenia beyond their first-episode of psychosis, and to investigate the impact of symptoms and functioning on these subjective experiences. METHODS: Fifty-one schizophrenia patients and 56 matched healthy controls participated in the study...

BACKGROUND: Depression that does not respond to antidepressants is treatment-resistant depression (TRD). TRD definitions include assessments of treatment response, dose and duration, and implementing these definitions in claims databases can be challenging. We built a data-driven TRD definition and evaluated its performance. METHODS: We included adults with depression, ≥1 antidepressant, and no diagnosis of mania, dementia, or psychosis. Subjects were stratified into those with and without proxy for TRD...

OBJECTIVE: Cognition is a complex trait representing a set of all mental abilities and processes related to knowledge. Although diverse brain regions are involved, most cognitive processes appear to engage cortical regions. The activity of dopaminergic neurons in prefrontal cortex represents a biological substrate underlying cognitive functions. Alzheimer's disease (AD) is the most frequent dementia associated with cognitive impairments. Cognitive impairment in AD starts slow with discrete deterioration in memory, language, thinking and reasoning, but it progresses into more severe and debilitating cognitive dysfunction...

AIM: We sought to examine attenuated first-rank symptoms (FRS) and subcomponents of the Unusual Thought Content (P.1.) section of the Structured Interview for Psychosis-Risk Syndromes (SIPS) to investigate the robust relationship between total P.1. and conversion. We hypothesized that attenuated FRS would drive the association and, additionally, be most predictive of a schizophrenia diagnosis. METHOD: We assessed 189 clinical high-risk participants. Two independent raters separately scored attenuated FRS and each subcomponent of P...
