The mental health needs of people with a learning disability detained in police custody

Few research studies examine the prevalence or mental health needs of people with a Learning Disability (LD) detained in police custody. This paper describes the population of detainees with an LD who presented to an inner city inter-agency police liaison service during a three-year period. Two forensically trained Community Mental Health Nurses (CMHNs) screened all custody record forms (n=9014) for evidence of a mental health problem or LD. The CMHNs interviewed positively screened detainees (n=1089) using a battery of measures designed to assess mental health status, risk-related behaviour and alcohol or drug abuse. Almost one-in-ten of those interviewed (95/1089) were judged to have a possible or definite LD. Fifty-two per cent were cases on the General Health Questionnaire (GHQ) whilst 61% attained 'above threshold' Brief Psychiatric Rating Scale (BPRS) scores. The majority (63%) had a history of causing harm to others while 56 per cent had a history of self-harm. More than half (56%) regularly consumed harmful levels of alcohol while one-in-four (27%) reported abusing drugs. Higher than expected numbers of detainees have a learning disability and most have complex mental health needs. A police liaison service offers a way of identifying people with LD and connecting them with appropriate health and social care agencies.

UK Food Standards Agency Workshop Report: Diet and Immune Function

The UK Food Standards Agency convened a workshop on 13 May 2009 to discuss recently completed research on diet and immune function. The objective of the workshop was to review this research and to establish priorities for future research. Several of the trials presented at the workshop showed some effect of nutritional interventions (e.g. vitamin D, Zn, Se) on immune parameters. One trial found that increased fruit and vegetable intake may improve the antibody response to pneumococcal vaccination in older people. The workshop highlighted the need to further clarify the potential public health relevance of observed nutrition-related changes in immune function, e.g. susceptibility to infections and infectious morbidity.

UK Food Standards Agency Workshop Report: carbohydrate and cardiovascular risk

This report summarises a workshop convened by the UK Food Standards Agency (FSA) on 14 October 2008 to discuss current FSA-funded research on carbohydrates and cardiovascular health. The objective of this workshop was to discuss the results of recent research and to identify any areas which could inform future FSA research calls. This workshop highlighted that the FSA is currently funding some of the largest, well-powered intervention trials investigating the type of fat and carbohydrate, whole grains and fruit and vegetables, on various CVD risk factors. Results of these trials will make a substantive contribution to the evidence on diet and cardiovascular risk.

Quantifying Alcohol-Related Mortality: Should Alcohol-Related Contributory Causes of Death be Included?

Aims: The aim of the study was to assess whether alcohol-related mortality data in the UK should be extended to include contributory as well as underlying cause of death. Methods: A total of 101,320 deaths registered in Northern Ireland between 2001 and 2007 were analysed to determine the quantity and characteristics of those with an underlying or contributory alcohol-related cause of death. Results: Alcohol was found to be an underlying cause of death in 1690 cases (1.7% of deaths) and a contributory cause in a further 1105 cases. Analyses show that the addition of alcohol-related contributory causes of deaths would increase the male-female ratio, result in steeper socio-economic gradients and amplify the apparent rate of increase of alcohol-related deaths. The significant contribution of alcohol to external causes of death, such as accidents and suicide, is also more evident. Conclusions: Using only underlying cause of death undoubtedly underestimates the burden of alcohol-related harm and may provide an inaccurate picture of those most likely to suffer from an alcohol-related death, especially among younger men.

Quantification of nanoparticle uptake by cells using microscopical and analytical techniques

Quantification of nanoparticles in biological systems (i.e., cells, tissues and organs) is becoming a vital part of nanotoxicological and nanomedical fields. Dose is a key parameter when assessing behavior and any potential risk of nanomaterials. Various techniques for nanoparticle quantification in cells and tissues already exist but will need further development in order to make measurements reliable, reproducible and intercomparable between different techniques. Microscopy allows detection and location of nanoparticles in cells and has been used extensively in recent years to characterize nanoparticles and their pathways in living systems. Besides microscopical techniques (light microscopy and electron microscopy mainly), analytical techniques such as mass spectrometry, an established technique in trace element analysis, have been used in nanoparticle research. Other techniques require 'labeled particles, fluorescently, radioactively or magnetically. However, these techniques lack spatial resolution and subcellular localization is not possible. To date, only electron microscopy offers the resolving power to determine accumulation of nanoparticles in cells due to its ability to image particles individually. So-called super-resolution light microscopy techniques are emerging to provide sufficient resolution on the light microscopy level to image or 'see particles as individual particles. Nevertheless, all microscopy techniques require statistically sound sampling strategies in order to provide quantitative results. Stereology is a well-known sampling technique in various areas and, in combination with electron microscopy, proves highly successful with regard to quantification of nanoparticle uptake by cells. © 2010 Future Medicine Ltd.

Experiences with mephedrone pre- and post-legislative controls: Perceptions of safety and sources of supply

Background: Drug scenes within several countries have changed in recent years to incorporate a range of licit psychoactive products, collectively known as “legal highs.” Hundreds of different legal high products have been described in the literature. Many of these products contain synthetic stimulants that allegedly
“mirror” the effects of some illicit drugs. In 2009–2010, growing concern by the UK and Irish governments focused on mephedrone, a synthetic stimulant that had become embedded within several drug scenes in Britain and Ireland. In April 2010, mephedrone and related cathinone derivatives were banned under
the UK’s Misuse of Drugs Act 1971. Setting aside “worse case scenarios” that have been portrayed by UK and Irish media, little is known about mephedrone use from the consumer’s perspective. The purpose of this paper was to (1) explore respondents’ experiences with mephedrone, (2) examine users’ perceptions
about the safety of mephedrone, and primarily to (3) examine sources of mephedrone supply during the pre- and post-ban periods.
Methods: Semi-structured interviews were conducted with 23 adults who had used mephedrone during 2009–2010. Data collection occurred in May and June 2010, following the ban on mephedrone. A total of 20/23 respondents had used mephedrone during the post-ban period, and the vast majority had prior
experience with ecstasy or cocaine. Respondents’ ages ranged from 19 to 51, approximately half of the sample were female and the majority (19 of 23) were employed in full- or part-time work.
Results: Most respondents reported positive experiences with mephedrone, and for some, the substance emerged as a drug of choice. None of the respondents reported that the once-legal status of mephedrone implied that it was safe to use. Very few respondents reported purchasing mephedrone from street-based
or on-line headshops during the pre-ban period, and these decisions were guided in part by respondents’ attempts to avoid “drug user” identities. Most respondents purchased or obtained mephedrone from friends or dealers, and mephedrone was widely available during the 10-week period following the ban. Respondents reported a greater reliance on dealers and a change in mephedrone packaging following the criminalisation of mephedrone.
Conclusion: The findings are discussed in the context of what appears to be a rapidly changing mephedrone market. We discuss the possible implications of criminalising mephedrone, including the potential displacement effects and the development of an illicit market.
