Monitoring metabolic side effects of atypical antipsychotics in people with an intellectual disability.

This audit was undertaken prospectively to examine the compliance of a group of psychiatrists against guidelines they developed for monitoring the onset of metabolic syndrome, a potential side effect of antipsychotic medication, especially second generation or atypical ones. Phase 1 of the audit was to set standards by a questionnaire survey of participating psychiatrists against Consensus Guidelines on monitoring (American Diabetic Association, 2004), which they favoured. The results led to modifying these guidelines to develop minimum acceptable standards against which their practice was audited in Phase 2.

Reactive sulphur species: an in vitro investigation of the oxidation properties of disulphide S-oxides.

We have recently proposed that disulphide S-monoxides (thiosulphinates) and disulphide S-dioxides (thiosulphonates) are formed from their parent disulphides and 'reactive oxygen species' during oxidative stress. These 'reactive sulphur species' are themselves strong oxidizing agents that preferably attack the thiol functionality. We now show that under conditions where disulphides show little effect, disulphide S-oxides rapidly modify metallothionein, alcohol and glyceraldehyde 3-phosphate dehydrogenases and a zinc finger-protein fragment in vitro.
