'Do More, Smoke Less!' Harm Reduction In Action For Smokers With Mental Health/Substance Use Problems Who Cannot Or Will Not Quit, Amanda Baker, Robin Callister, Peter Kelly, Kypros Kypri
Peter Kelly
Although smoking rates among mental health/substance abusing populations are very high, the focus of treatment and research has tended to be on substances other than tobacco.A range of harm-reduction strategies is needed, including long-term nicotine maintenance, smokeless tobacco and ‘clean’ nicotine products. For those who cannot or will not quit, assistance in reducing smoking should be given. Interventions for smoking among people with mental health/substance use problems may best be delivered by addressing multiple health-risk behaviours, especially physical activity, around the same time.

The Mna, But Not The Determine, Screening Tool Is A Valid Indicator Of Nutritional Status In Elderly Africans, Karen Charlton, Tracy Kolbe-Alexander, Johanna Nel
The Mna, But Not The Determine, Screening Tool Is A Valid Indicator Of Nutritional Status In Elderly Africans, Karen Charlton, Tracy Kolbe-Alexander, Johanna Nel
Karen E. Charlton
Objectives: To compare the validity of existing nutrition screening tools for use in older South Africans. Design: A cross-sectional study in 283 free-living and institutionalized black South Africans aged 60+ years.Methods: Trained fieldworkers administered a 24-hour recall, the DETERMINE and Mini Nutritional Assessment (MNA) screening tools and performed anthropometrical measurements and physical function tests. Biochemical indicators assessed included serum albumin; haemoglobin, ferritin, vitamin B12, RBC folate, cholesterol and vitamin C. The 6-item Cognitive Impairment Test was used to assess cognitive function.Results: MNA score was positively and significantly associated with anthropometrical measurements, cognitive function, IADL and, in women only, % body …

Background: Numerous studies report dysfunctional dopaminergic and noradrenergic neurotransmission in the pathogenesis of schizophrenia. Dopamine beta-hydroxylase (DBH) is an intracellular enzyme catalyzing the conversion of dopamine to noradrenaline. Functional polymorphisms have been reported in the promoter region of DBH gene, including a 19 bp insertion/deletion polymorphism. The purpose of this study was to investigate whether there was an association between the functional polymorphism (DBH50-Ins/Del) and schizophrenia in a Han Chinese population. Methods: This polymorphism was genotyped in 221 first-episode schizophrenics, 360 chronic schizophrenics and 318 healthy controls using a case-control design. We assessed their psychopathology using the Positive and Negative …
Equilibrium Constraints But Not Joint Constraints Determine Hand Trajectory Planning, C Paizis, C Papaxanthis, P Stapley, T Pozzo
Equilibrium Constraints But Not Joint Constraints Determine Hand Trajectory Planning, C Paizis, C Papaxanthis, P Stapley, T Pozzo
Dr Paul J Stapley
Introduction: Equilibrium constraints play a major role in finger trajectory formation and curved hand paths seem to be the result of a strong coupling between postural and focal task components. However, such curvatures might also result from joint constraints. To test this hyputhesis we investigated the elrect of imposed joint strategies and support conditions on hand trajectory formation during a pointing task beyond arm's length.
