The nature of associations between recent cannabis use and negative symptoms, positive symptoms, and neurocognitive deficits remains unclear. In a relatively large sample of well-characterized patients with first-episode psychosis, we hypothesized that, compared to first-episode patients without cannabis use in the three months prior to first hospitalization, those having used cannabis would have lesser negative symptoms, greater positive symptoms, and no differences in cognitive functioning. Dose-response relationships were also examined.

Between 2008 and 2013, 247 first-episode psychosis patients were assessed during their hospitalization at one of six participating inpatient psychiatric units. Measures included the Longitudinal Substance Use Recall for 12Weeks instrument, the Scale for the Assessment of Negative Symptoms, the Scale for the Assessment of Positive Symptoms, and the MATRICS Consensus Cognitive Battery (MCCB).

Anhedonia-asociality was significantly lower among those using cannabis in thesubgroups of individuals with first-episode psychosis, as well as risk factors for cannabis use in the early course of these disorders.
Suicide is a leading cause of death in persons with schizophrenia and other serious mental illnesses (SMI), however, little is known about the characteristics and circumstances of suicide decedents with SMI in the US compared to those with other or no known mental illness.

This study was a retrospective analysis of suicide deaths in individuals aged ≥18years from the National Violent Death Reporting System, 2003-2017. Odds ratios compared sociodemographic and clinical characteristics, cause of death, precipitating circumstances, and post-mortem toxicology results. All analyses were stratified by gender.

Of the 174,001 suicide decedents, 8.7% had a known SMI, 33.0% had other mental disorders, and 58.2% had no known mental illness. Relative to persons with other mental disorders, SMI decedents were younger and more likely to have previous suicide attempts and co-occurring drug use. Problems with intimate partners, poor physical health, and recent institutional release were the most common precipitating circumstances for SMI decedents. Firearms were the most common suicide method for males with SMI. Although 67.0% male and 76.0% of female SMI decedents were currently in treatment, toxicology results suggest many were not taking antipsychotic or antidepressant medications at the time of death.

Persons with SMI are over-represented in suicide deaths. Efforts to improve treatment of co-occurring substance use disorders, continuity of care following hospitalization, medication adherence, and to reduce access to firearms are important suicide prevention strategies.

Several brain regions implicated in schizophrenia exhibit decreased levels of dysbindin-1, which may affect copper homeostasis therein. Our recent study showed decreased levels of dysbindin-1, the copper transporter-1 (CTR1) and copper in the substantia nigra in schizophrenia, providing the first evidence of disrupted copper transport in schizophrenia. In the present study, we hypothesized that there would be lower levels of dysbindin-1 and CTR1 in the hippocampus in schizophrenia versus a comparison group. Using semi-quantitative immunohistochemistry for dysbindin1 and CTR1, we measured the optical density in a layer specific fashion in the hippocampus and entorhinal cortex in ten subjects with schizophrenia and ten comparison subjects. Both regions were richly immunolabeled for CTR1 and dysbindin1 in both groups. In the superficial layers of the entorhinal cortex, CTR1 immunolabeled neuropil and cells showed lower optical density values in patients versus the comparison group. In the molecular layer of the dentate gyrus, patients had higher optical density values of CTR1 versus the comparison group. The density and distribution of dysbindin-1 immunolabeling was similar between groups. These laminar specific alterations of CTR1 in schizophrenia suggest abnormal copper transport in those locations.Social exclusion and rejection have deleterious effects on psychological well-being. Research documents the negative effects of social exclusion and rejection on psychiatric problems like depression, social anxiety disorder, and non-suicidal self-injury. Additionally, prior research suggests that individuals with and at-risk for psychosis spectrum disorders may also be negatively affected by exclusion and rejection. Moreover, those on the psychosis spectrum may be at an even greater risk to experience social exclusion due to poor social functioning and the stigma surrounding the disorder. This systematic review aimed to investigate how individuals across the psychosis spectrum respond to social exclusion and rejection. We systematically searched PubMed and PsycINFO databases to identify studies that met the following eligibility criteria 1) investigated social exclusion or rejection, 2) targeted a psychosis-related sample or symptoms, and 3) was an empirical study. 13 studies satisfied our eligibility criteria and were subsequently reviewed. Despite methodological variation and samples spanning the psychosis spectrum, the majority of the literature supports the conclusion that those with psychosis spectrum disorders report similar levels of exclusion-induced distress compared to healthy controls, but process and cope with exclusion differently, both behaviorally and neurobiologically.Abnormalities in resting-state electroencephalogram (rs-EEG) activity have been previously reported in schizophrenia. While most rs-EEG recordings were performed in patients with chronic schizophrenia during eyes closed (EC), only a handful of studies have investigated rs-EEG activity during both EC and eyes open (EO) conditions. It is also unknown whether EC and EO rs-EEG alterations are present at illness onset, and whether they change during the day. Here, we performed EC and EO rs-EEG recordings in the morning (AM) and evening (PM) in twenty-six first-episode psychosis (FEP) patients and seventeen matched healthy controls (HC). In AM/EC rs-EEG, a widespread reduction was found in low alpha power in FEP relative to HC. In PM/EC, the FEP group demonstrated a trend toward decreased theta power in parietal regions, while decreased high alpha power in frontal and left parietal regions was present during PM/EO. AG120 Moreover, reduced low alpha power during AM/EC was associated with worse positive symptoms. Altogether, those findings indicate that rs-EEG alterations are present in FEP patients at illness onset, that they are linked to the severity of their psychosis, and that distinct RS abnormalities can be detected in different conditions of visual alertness and time of the day.
