This study aimed to investigate the risk of self-harm following diagnosis of different psychiatric disorders in an Asian population, through a review of inpatient records retrieved from the Hong Kong Clinical Data Analysis and Reporting System (CDARS).MethodsFor this nested case-control study, the inpatient data of people admitted for any reason to Hong Kong public hospitals, between Jan 1, 2000, and Dec 31, 2010, were extracted from CDARS. Cases were people aged 10 years or older who had been admitted to inpatient care with a first-listed record of psychiatric disorder during the study period. The seven psychiatric disord...

Authors: Jahołkowski P, Niewiadomska J, Wciórka J, Kowalski M, Świtaj P Abstract Clozapine, atypical antipsychotic drug, is widely used in patients with schizophrenia, for whom previous therapy was inadequate or not tolerated. Clozapine-induced myocarditis (CIM) is a relatively rare but potentially life-threatening complication of clozapine therapy; however, the underlying mechanism has not been so far well elucidated. Factors predisposing to CIM include a rapid dose titration, advanced age and co-administration of sodium valproate. In this paper, we present a case of a 22-year-old male patient with refrac...

Psychiatric disorders impose a huge burden on individuals, families, and society. The Alu repeat sequence is a member of the short interspersed nuclear element (SINE) family of mammalian genomes, however, its expression pattern and role in psychiatric disorders is unclear. The current paper aimed at determining the concentrations of Alu in patients with schizophrenia (SZ), major depressive disorder (MDD), and alcohol-induced psychotic disorder (AIPD), and to further define the role and value of Alu as a potential biomarker in psychiatric disorders. In this work, we found that the concentration of Alu was considerably incre...

Authors: Barton BB, Segger F, Fischer K, Obermeier M, Musil R Abstract Introduction: Antipsychotic-induced weight-gain (AIWG) is a very important, yet often neglected side-effect in the treatment with first and second generation antipsychotics. AIWG can increase the risk of developing metabolic syndrome, diabetes and cardiovascular disease. Meta-analyses mostly concentrate on AIWG in schizophrenic and bipolar patients, even though antipsychotics are prescribed off-label across many other diagnostic groups (e.g. anxiety disorders, depression, autistic disorder).Areas covered: Pub Med and Web of Science were systemat...

Myelin is the sheathing of nerves, essential to their function. Excessive loss produces disabling and ultimately fatal conditions such as multiple sclerosis, but we all lose myelin integrity to some degree as a consequence of the damage and dysfunction of degenerative aging. This most likely contributes to cognitive decline and other age-related issues. A number of different approaches have been identified to boost the operation of the normal maintainance processes that remyelinate nerves, such as FGF21 upregulation, or increasing the size of remyelinating cell populations. Here, researchers discover another possible trigg...

In conclusion, despite contrasting neurochemical profiles, partial glycine site agonists and glycine reuptake inhibitors exhibit comparable pro-cognitive effects in rats of poten tial relevance to treatment of schizophrenia and other brain disorders where cognitive performance is impaired.

CONCLUSIONS: This study is the first to describe the structural hemispheric lateralization and organization of the visuospatial attentional network in persons with schizophrenia. The main findings indicate loss of integrity in the SLF II, associated with loss of asymmetry in participants with schizophrenia, compared with healthy individuals, suggesting a potential substrate of attentional deficits.
