Internet-based indicated prevention for panic disorder: An effectiveness trial in primary care

Previous studies have shown that an internet delivered indicated prevention program for panic disorder can be effective. However, those studies were done with select populations. Most individuals who are at risk for panic disorder present to hospital emergency rooms and primary care settings. This paper reports on a study currently being undertaken in Scotland where the program is being trialed in primary care. The intervention and experimental design will be described. However the key research question is whether General Practitioners will make use of the internet-based intervention system. Preliminary results will be reported. The results of the study will have implications for the way that primary care is recruited into the prevention of mental health problems.

The prediction of disease risk in genomic medicine

In recent years, the phrase 'genomic medicine' has increasingly been used to describe a new development in medicine that holds great promise for human health. This new approach to health care uses the knowledge of an individual's genetic make-up to identify those that are at a higher risk of developing certain diseases and to intervene at an earlier stage to prevent these diseases. Identifying genes that are involved in disease aetiology will provide researchers with tools to develop better treatments and cures. A major role within this field is attributed to 'predictive genomic medicine', which proposes screening healthy individuals to identify those who carry alleles that increase their susceptibility to common diseases, such as cancers and heart disease. Physicians could then intervene even before the disease manifests and advise individuals with a higher genetic risk to change their behaviour - for instance, to exercise or to eat a healthier diet - or offer drugs or other medical treatment to reduce their chances of developing these diseases. These promises have fallen on fertile ground among politicians, health-care providers and the general public, particularly in light of the increasing costs of health care in developed societies. Various countries have established databases on the DNA and health information of whole populations as a first step towards genomic medicine. Biomedical research has also identified a large number of genes that could be used to predict someone's risk of developing a certain disorder. But it would be premature to assume that genomic medicine will soon become reality, as many problems remain to be solved. Our knowledge about most disease genes and their roles is far from sufficient to make reliable predictions about a patient’s risk of actually developing a disease. In addition, genomic medicine will create new political, social, ethical and economic challenges that will have to be addressed in the near future.

The prospects for immunotherapy in smoking cessation

Context Smoking is a major preventable cause of death and disability that is maintained by dependence on nicotine. Smoking cessation reduces mortality and morbidity. Although existing pharmacological aids to smoking cessation and relapse prevention (nicotine replacement therapy and bupropion) improve on unassisted quitting and behavioural methods, they are only modestly effective. More effective pharmacological methods are required that improve compliance, reduce side-effects, and can be used in combination with existing cessation methods. Starting point A nicotine vaccine is a promising immunotherapeutic approach to smoking cessation and relapse prevention. Such a vaccine would induce the immune system to form specific antibodies to nicotine to prevent it from crossing the blood-brain barrier to act on receptor sites in the central nervous system. Recent studies in rats provide proof of principle by showing that nicotine-specific antibodies can prevent the reinstatement of nicotine self-administration (N Lindblom et al, Respiration 2002; 69: 254–60) and block dopamine release in the shell of the nucleus accumbens (Sde Villiers et al, Respiration 2002; 69: 247–53). A phase 1 trial of a human cocaine vaccine has also recently been successfully completed (T Kosten et al, Vaccine 2002; 20: 1196–204). A safe and effective human nicotine vaccine would potentially have fewer side-effects and better compliance than existing smoking-cessation pharmacotherapies. It could also be used in combination with some of them (eg, bupropion). Where next? The most promising clinical application of a human nicotine vaccine is likely to be in relapse prevention in abstinent smokers. A vaccine may also have a role in preparing smokers to quit. Clinical trials of safety and efficacy in human smokers and ex-smokers are warranted. If a nicotine vaccine proves to be safe and effective, the health-care system will need to ensure that it is registered for clinical use and that the poorer members of the community (among whom smoking prevalence is now highest in developed countries) have access to the vaccine. The community will need to be appropriately informed about the role of a nicotine vaccine to ensure that it is not prematurely used for preventive purposes in children and adolescents.

Health and safety issues in contemporary dental practice

Under current workplace health and safety legislation, the owners and managers of a dental practice have a legal responsibility to provide staff with a safe working environment. In this article, the emphasis will be on four common areas of risk: posture when seated, handling scalpel blades, flooring and lighting.

Family orientated delivery of routine nursing care in hospital

Hospital nursing may be better deployed to acute clinical patient care. The recruitment of family assistance will facilitate this process in patients in hospital awaiting placement and without acute care issues.

Reducing problem behavior during care-giving in families of preschool-aged children with developmental disabilities

This study evaluated two variants of a behavioral parent training program known as Stepping Stones Triple P (SSTP) using 74 preschool-aged children with developmental disabilities. Families were randomly allocated to an enhanced parent training intervention that combined parenting skills and care-giving coping skills (SSTP-E), standard parent training intervention alone (SSTP-S) or waitlist control (WL) condition. At post-intervention, both programs were associated with lower levels of observed negative child behavior, reductions in the number of care-giving settings where children displayed problem behavior, and improved parental competence and satisfaction in the parenting role as compared with the waitlist condition. Gains attained at post-intervention were maintained at 1-year follow-up. Both interventions produced significant reductions in child problem behavior, with 67% of children in the SSTP-E and 77% of children in the SSTPS showing clinically reliable change from pre-intervention to follow-up. Parents reported a high level of satisfaction with both interventions.
