Mentally disordered offenders and the European Court of Human Rights

This article presents the findings from a study of cases taken to the European Court of Human Rights by mentally disordered offenders. The issues raised include the problems raised by indeterminate sentences, the use of detention for preventive purposes, and debates about treatment. The countries represented are Belgium, Norway, Poland, the Netherlands, Russia and the United Kingdom.

Factor structure and validity of the Alcohol Use Disorders Identification Test (AUDIT) in a sample of mentally disordered offenders

Investigations of the factor structure of the Alcohol Use Disorders Identification Test (AUDIT) have produced conflicting results. The current study assessed the factor structure of the AUDIT for a group of Mentally Disordered Offenders (MDOs) and examined the pattern of scoring in specific subgroups. The sample comprised 2005 MDOs who completed a battery of tests including the AUDIT. Confirmatory factor analyses revealed that a two-factor solution – alcohol consumption and alcohol-related consequences – provided the best data fit for AUDIT scores. A three-factor solution provided an equally good fit, but the second and third factors were highly correlated and a measure of parsimony also favoured the two-factor solution. This study provides useful information on the factor structure of the AUDIT amongst a large MDO population, while also highlighting the difficulties associated with the presence of people with mental health problems in the criminal justice system.

Community Care Services for the Mentally Ill

In this study a broadly representative sample of clients in the City of Westminster, receiving Care in the Community for reasons of mental ill-health, were interviewed regarding their experiences of, and levels of satisfaction with, services provided. The results reveal the vulnerability of services users, the benefits of community care, the high regard the majority have for their helpers, the limitations imposed by scarce resources, and the negative effects of only loose co-ordination between health and social services. Respondents also provide a rich source of data on how services might be improved.

Degradation of the polycyclic aromatic hydrocarbon (PAH) fluorene is retarded in a Scots pine ectomycorrhizosphere

Polycyclic aromatic hydrocarbons (PAHs) are an important class of persistent organic pollutants (POPs) in the environment and accumulate in forest soils. These soils are often dominated by ectomycorrhizal (EcM) roots, but little is known about how EcM fungi degrade PAHs, or the overall effect of field colonized EcM roots on the fate of PAHs. The ability of eight EcM fungi to degrade PAHs in liquid culture spiked with ¹⁴C labelled PAHs was investigated. Microcosms were used to determine the impact of naturally colonized mycorrhizal pine seedlings on PAH mineralization and volatilization. Only two EcM fungi (Thelephora terrestris and Laccaria laccata) degraded at least one PAH and none were able to mineralize the PAHs in pure culture. Where degradation occurred, the compounds were only mono-oxygenated. EcM pine seedlings did not alter naphthalene mineralization or volatilization but retarded fluorene mineralization by 35% compared with unplanted, ectomycorrhizosphere soil inoculated, microcosms. The EcM fungi possessed limited PAH degrading abilities, which may explain why EcM dominated microcosms retarded fluorene mineralization. This observation is considered in relation to the 'Gadgil-effect', where retarded litter decomposition has been observed in the presence of EcM roots. © New Phytologist (2004).

Paracetamol-Loaded Poly(ε-caprolactone) Layered Silicate Nanocomposites

The work described in this paper demonstrates a combined novel approach to the preparation of drug loaded poly(e-caprolactone) layered silicate nanocomposites using hot melt extrusion, a continuous process in contrast to the normal batch type processing used to prepare polymeric drug delivery systems, and most significantly the use of high surface area, large aspect ratio inorganic nanoplatelets to retard drug release. The methodology and results described in this article are significant and could equally be applied to the controlled/retarded release of any bio-active molecule (pharmaceutical, nutraceutical, protein, DNA/iRNA, anti-microbial, anti-coagulant, etc.) from biopolymers and the production of medical devices from such composite materials.

A Census-based longitudinal study of variations in survival amongst residents of nursing and residential homes in Northern Ireland

Background: despite the intensive services provided to residents of care homes, information on death rates is not routinely available for this population in the UK. Objective: to quantify mortality rates across the care home population of Northern Ireland, and assess variation by type of care home and resident characteristics. Design: a prospective, Census-based cohort study, with 5-year follow-up. Participants: all 9,072 residents of care homes for people aged 65 and over at the time of the 2001 census with a special emphasis on the 2,112 residents admitted during the year preceding census day. Measurements: age, sex, self-reported health, marital status, residence (not in care home, residential home, dual registered home, nursing home), elderly mentally infirm care provision. Results: the median survival among nursing home residents was 2.33 years (95% CI 2.25–2.59), for dual registered homes 2.75 (95% CI 2.42–3.17) and for residential homes 4.51 (95% CI 3.92–4.92) years. Age, sex and self-reported health showed weaker associations in the sicker populations in nursing homes compared to those in residential care or among the non-institutionalised. Conclusions: the high mortality in care homes indicates that places in care homes are reserved for the most severely ill and dependent. Death rates may not be an appropriate care quality measure for this population, but may serve as a useful adjunct for clinical staff and the planning of care home provision.
