Explaining trends in alcohol-related harms in Scotland 1991-2011 (II): policy, social norms, the alcohol market, clinical changes and a synthesis.

OBJECTIVE: To provide a basis for evaluating post-2007 alcohol policy in Scotland, this paper tests the extent to which pre-2007 policy, the alcohol market, culture or clinical changes might explain differences in the magnitude and trends in alcohol-related mortality outcomes in Scotland compared to England & Wales (E&W). STUDY DESIGN: Rapid literature reviews, descriptive analysis of routine data and narrative synthesis. METHODS: We assessed the impact of pre-2007 Scottish policy and policy in the comparison areas in relation to the literature on effective alcohol policy. Rapid literature reviews were conducted to assess cultural changes and the potential role of substitution effects between alcohol and illicit drugs. The availability of alcohol was assessed by examining the trends in the number of alcohol outlets over time. The impact of clinical changes was assessed in consultation with key informants. The impact of all the identified factors were then summarised and synthesised narratively. RESULTS: The companion paper showed that part of the rise and fall in alcohol-related mortality in Scotland, and part of the differing trend to E&W, were predicted by a model linking income trends and alcohol-related mortality. Lagged effects from historical deindustrialisation and socio-economic changes exposures also remain plausible from the available data. This paper shows that policy differences or changes prior to 2007 are unlikely to have been important in explaining the trends. There is some evidence that aspects of alcohol culture in Scotland may be different (more concentrated and home drinking) but it seems unlikely that this has been an important driver of the trends or the differences with E&W other than through interaction with changing incomes and lagged socio-economic effects. Substitution effects with illicit drugs and clinical changes are unlikely to have substantially changed alcohol-related harms: however, the increase in alcohol availability across the UK is likely to partly explain the rise in alcohol-related mortality during the 1990s. CONCLUSIONS: Future policy should ensure that alcohol affordability and availability, as well as socio-economic inequality, are reduced, in order to maintain downward trends in alcohol-related mortality in Scotland.

Alternative biofuel production in non-natural hosts.

Global energy and environmental concerns have stimulated increased efforts in synthesizing petroleum-derived products from renewable resources. Biological production of metabolites for fuel is increasingly becoming a feasible, renewable, environmentally sound alternative. However, many of these chemicals are not highly produced in any known native organism. Here we review the current progress of modifying microorganisms with heterogeneous elements for the production of biofuels. This strategy has been extensively employed in a variety of hosts for the development of production of various alcohols, fatty acids, alkenes and alkanes.

Queimaduras com álcool em crianças: realidade brasileira e vulnerabilidades / Alcohol burns in children: Brazilian reality and vulnerabilities

Grande número de casos de queimaduras com álcool entre adultos e crianças é frequentemente apontado nas casuísticas nacionais. A Resolução da ANVISA (Agência Nacional de Vigilância Sanitária) de 2002, que restringia a comercialização de álcool em grandes concentrações para uso doméstico, foi o reconhecimento oficial da existência deste tipo de queimadura como um problema social e de saúde pública. Dias antes de findar o prazo de adequação à medida, os maiores fabricantes do produto foram liberados de a acatarem. Passados alguns anos, buscou-se, na presente tese de doutorado, apreciar quesitos surgidos no debate de então, os quais ainda permanecem, dada sua relevância. Para melhor evidenciar os contornos e as implicações da questão abordada pela iniciativa governamental, este trabalho teve como objetivos: caracterizar a magnitude do problema das queimaduras no Brasil através da análise crítica das informações disponíveis e reconhecer os tipos mais frequentes da lesão; descrever a casuística de um centro brasileiro de referência no tratamento de queimaduras e situá-la em relação ao contexto nacional e internacional; caracterizar cenários e circunstâncias em que crianças foram vítimas de queimaduras com álcool, dentro de uma população delimitada; interpretar, instruídos pelo conceito de vulnerabilidade, as relações dinâmicas e as combinações existentes entre as condições individuais e sociais presentes nos contextos em que crianças sofrem queimaduras com álcool. A investigação empírica aliou ao método epidemiológico descritivo o enfoque qualitativo, apoiado em entrevistas em profundidade a partir de roteiro temático. Os dados permitiram sustentar que o Brasil exibe em seu perfil epidemiológico características que não são encontradas na literatura produzida em outras partes do mundo: alta proporção de queimaduras com álcool entre pacientes hospitalizados, sejam adultos ou crianças.

Amount of alcohol-based hand rub used and incidence of hospital-acquired bloodstream infection in a danish hospital.

We investigated the association between the amount of alcohol-based hand rub (hereafter, "hand rub") used and the incidence of healthcare-acquired bloodstream infection (HCR-BSI) from 2004 through early 2008. The amount of hand rub used increased significantly, and the incidence of HCR-BSI remained stable. There was no significant association between the amount of hand rub used and the incidence of HCR-BSI.

A systematic review on the effectiveness of alcohol-based solutions for hand hygiene.

The use of alcohol has been proposed as an option for hand hygiene. A systematic review was conducted to evaluate the clinical evidence supporting the use of alcohol-based solutions in hospitals as an option for hand hygiene. Studies published between January 1992 and April 2002 in English and Thai, related to the effectiveness of alcohol-based solutions, were reviewed. The databases searched included Medline, DARE, CINAHL and Dissertation Abstracts International. All studies were assessed as having adequate methodological quality. Results of this systematic review supported that alcohol-based hand rubbing removes microorganisms effectively, requires less time and irritates hands less often than does handwashing with soap or other antiseptic agents and water. Furthermore, the availability of bedside alcohol-based solutions increases compliance with hand hygiene among health care workers.
