News Round-Up: August 2009 2nd Edition

Research in Psychosis

In a study in which two psychiatrists assessed 100 inpatients, the diagnosis of schizophrenia was found to occur more frequently when using ICD-10 criteria compared DSM-IV and the researchers suggest that this might be due to the absence of an exclusion of an affective syndrome in ICD-10 (although there are references to affective symptomatology in ICD-10)(Cheniaux et al, 2009). In a longitudinal structural MRI study, people with schizophrenia were divided into good and poor outcome groups and in the latter group there was found to be a significant assocation with reduction in the volume of the putamen (Mitelman et al, 2009). In an 18-week double-blind flexible dosing study (n=147) of Clozapine and Ziprasidone in people with treatment-resistant schizophrenia the researchers concluded that both medications showed similar efficacy with reduction in PANSS scores being the primary outcome measure (Sacchetti et al, 2009).

Miscellaneous Research

In a study of residents in long-term care who were referred for psychiatric assessment (n=868) there was found to be elevated Thyroid Stimulating Hormone (TSH) in 10.8% of people and a significant association of elevated TSH with female gender (Sabeen et al, 2009).

News in Brief

In a recent poll by the Royal Pharmaceutical Society of  457 people over the age of 65, just under half of respondents reported that they were taking 5 or more medications and 60% thought that they were experiencing adverse side-effects. There has been a suggestion of closer monitoring of antipsychotic initiation in older adults with diabetes following the results of a longitudinal study of 13,817 older adults (>65 years) who had commenced antipsychotics and finding that compared to a group who had stopped antipsychotic medication 180 days previously there was an elevated prevalence of hyperglycaemia. In a recent poll of 2000 people over the age of 16, there were found to be gaps in knowledge in the respondents in areas of potential importance – for instance 26% of respondents did not think there were approaches to reducing their risk of developing dementia.
