Synthesis and characterization of immobilized PAMAM dendrons.

This communication describes the synthesis and characterization of immobilized PAMAM dendrons onto a surface modified silicon wafer substrate (functionalized using plasma polymerized PAA) using a "growing from" strategy.

Substance misuse, anxiety and depression and urgency of presentation to a public emergency department in Australia.

Objectives: To establish the prevalence and comorbidity of substance-related problems and anxiety and depression, among ED presentations, and to compare the prevalence of these conditions among more and less urgent presentations.

Design And Setting: Cross-sectional survey of ED presentations over a 14 day period (24 h/day) at the Gold Coast Hospital Emergency Department in south-east Queensland, Australia, in October 2002.

Measures: Usual level of alcohol consumption (Alcohol Use Disorders Identification Test), acute alcohol and illicit drug use (during 24 h prior to interview), symptoms of anxiety and depression (Hospital Anxiety and Depression Scale) and triage category (Australasian Triage Scale).

Gender differences in the relationships between alcohol, tobacco and mental health in patients attending an emergency department.

Aims: There is evidence of a non-linear relationship between alcohol consumption and mental health status, and of an association between tobacco use and poor mental health. This paper examines the nature of the association between usual alcohol consumption, tobacco use and symptoms of anxiety and depression in Emergency Department patients in Queensland, Australia.

Methods: A cross sectional survey of patients aged 16-84 presenting for treatment over a 14 day period to Gold Coast Hospital Emergency Department using socio-demographic items, the Alcohol Use Disorders Identification Test (AUDIT) to measure moderate, hazardous and harmful alcohol consumption, and the Hospital Anxiety and Depression Scale (HADS) to measure state anxiety and depression.
