A mental health diagnosis can be stigmatising, so privacy and access to hospital-based patient cohorts is carefully controlled. Our team describe a pragmatic portal recruitment process for facilitating timely recruitment into multiple research studies focusing o...

We examined the concentrations of chemokines and related substances in the brain tissue from these two groups using the Bio-Plex Pro™ Human Chemokine Panel 40-Plex. We performed multiple regression analysis with covariates. The levels of CCL1, CCL8, CCL13, CCL15, CCL17, CCL19, CCL20, CXCL11, and IL-10 were significantly decreased, whereas the IL-16 levels were significantly increased in the suicide completers after adjustment with the Benjamini-Hochberg method to control for type Ⅰ errors (Q

ConclusionWe confirm the emerging evidence of a decreasing long-term diagnostic stability of schizophrenia, and a protective role of female sex. The association between premorbid intelligence and symptomatic remission underscores the pertinence of including cognitive deficits in the diagnostic category of schizophrenia. The association between younger age at diagnosis and symptomatic remission may reflect positive effects of early detection or a drift in the interpretation of the diagnostic classification system.

Most of the world's population now lives in cities. While living in cities have both health risks and benefits, mental health has been usually considered to be negatively affected by urbanicity. While mental health disorders have complex etiology and multiple causes, it has been shown in multiple observational studies that mood and anxiety disorders are more prevalent in urban centers and incidence has been increasing. In addition, the incidence of schizophrenia is strongly increased in people born and raised in cities.

Howlett Cannabinoid receptor interacting protein 1a (CRIP1a) is an important CB1 cannabinoid receptor-associated protein, first identified from a yeast two-hybrid screen to modulate CB1-mediated N-type Ca2+ currents. In this paper we review studies of CRIP1a function and structure based upon in vitro experiments and computational chemistry, which elucidate the specific mechanisms for the interaction of CRIP1a with CB1 receptors. N18TG2 neuronal cells overexpressing or silencing CRIP1a highlighted the ability of CRIP1 to regulate cyclic adenosine 3′,5′monophosphate (cAMP) production and extracellular...

This study determines the relationship between cognition and vascular burden in patients with SMD. Methods: Sixty SMD patients (61% men, mean age: 46) attending a psychosocial rehabilitation centre were included. We evaluated sociodemographic, clinical, laboratory, quality of life and functionality characteristics. And we analysed the association between cognitive performance and vascular burden. Results: SMD diagnoses were: 41.7% schizophrenia, 20.0% bipolar, 5.0% schizoaffective, 21.7% depressive and 11.7% other. Cognitive impairment was present in 55% of the cases. The average vascular burden was 3.2. Patients with cogn...

ConclusionThis case highlights the importance of maintaining a high index of suspicion when encountering psychiatric patients with nonspecific lower abdominal or anorectal pain with inconsistent presentations. Controversy exists regarding the type of surgical treatment in case of anorectal perforation. More research is needed to provide surgeons with evidence-based standardized methods for dealing with these rare pathologies.

ConclusionThis study supports the self ‐medication hypothesis. Nonetheless, considering the serious health hazard associated with tobacco use, we should encourage patients to stop smoking. Further investigations are warranted to determine the tobacco constituents that are beneficial or harmful to schizophrenia.

An increasing number of antipsychotic medications have demonstrated efficacy in randomized placebo-controlled trials in the treatment of children and adolescents with schizophrenia. This review summarizes and synthesizes relevant antipsychotic medication studies, with particular emphasis on second-generation agents, and discusses other clinical considerations that may influence medication selection. With the exception of clozapine demonstrating superior efficacy in the improvement of psychotic symptoms in treatment-resistant patients, many antipsychotic agents have been shown to be similarly efficacious, including first-ge...
