Supported Housing for People with Severe Mental Disorders

Background There has been a significant reduction in the number of people with severe mental illness who spend extended periods in long-stay hospitals. District health authorities, local authorities, housing associations and voluntary organisations are jointly expected to provide support for people with severe mental disorder/s. This 'support' may well involve some kind of special housing. Objectives To determine the effects of supported housing schemes compared with outreach support schemes or 'standard care' for people with severe mental disorder/s living in the community. Search methods For the 2006 update we searched the Cochrane Schizophrenia Group Trials Register (April 2006) and the Cochrane Central Register of Controlled Trials (CENTRAL, 2006 Issue 2). Selection criteria We included all relevant randomised, or quasi-randomised, trials dealing with people with 'severe mental disorder/s' allocated to supported housing, compared with outreach support schemes or standard care. We focused on outcomes of service utilisation, mental state, satisfaction with care, social functioning, quality of life and economic data. Data collection and analysis We reliably selected studies, quality rated them and undertook data extraction. For dichotomous data, we would have estimated relative risks (RR), with the 95% confidence intervals (CI). Where possible, we would have calculated the number needed to treat statistic (NNT). We would have carried out analysis by intention-to-treat and would have summated normal continuous data using the weighted mean difference (WMD). We would have presented scale data for only those tools that had attained pre-specified levels of quality and undertaken tests for heterogeneity and publication bias. Main results Although 139 citations were acquired from the searches, no study met the inclusion criteria. Authors' conclusions Dedicated schemes whereby people with severe mental illness are located within one site or building with assistance from professional workers have potential for great benefit as they provide a 'safe haven' for people in need of stability and support. This, however, may be at the risk of increasing dependence on professionals and prolonging exclusion from the community. Whether or not the benefits outweigh the risks can only be a matter of opinion in the absence of reliable evidence. There is an urgent need to investigate the effects of supported housing on people with severe mental illness within a randomised trial.

Protein kinases C: potential targets for intervention in diabetic nephropathy

Protein kinases C are a family of serine threonine protein kinases that play key roles in extracellular signal transduction. Inappropriate activation of protein kinase C has been implicated in the pathophysiology of many diseases, including diabetes mellitus. Indeed, protein kinase C activation may contribute not only to the pathogenesis of diabetic complications such as nephropathy and retinopathy, but also to insulin resistance. Growing awareness that protein kinase C isoforms subserve specific subcellular functions has led to the development of isoform-specific inhibitors, which may be useful investigational tools and therapeutic agents for attenuating the effects of inappropriate protein kinase C activity. Here we review the role played by protein kinases C in diabetic nephropathy and the recent progress that has been made to modulate its activity using specific inhibitors.

Non-genetic mechanisms communicating antibiotic resistance:rethinking strategies for antimicrobial drug design

Introduction: Infections by multidrug-resistant bacteria are of great concern worldwide. In many cases, resistance is not due to the presence of specific antibiotic-modifying enzymes, but rather associated with a general impermeability of the bacterial cell envelope. The molecular bases of this intrinsic resistance are not completely understood. Moreover, horizontal gene transfers cannot solely explain the spread of intrinsic resistance among bacterial strains. Areas covered: This review focuses on the increased intrinsic antibiotic resistance mediated by small molecules. These small molecules can either be secreted from bacterial cells of the same or different species (e.g., indole, polyamines, ammonia, and the Pseudomonas quinolone signal) or be present in the bacterial cell milieu, whether in the environment, such as indole acetic acid and other plant hormones, or in human tissues and body fluids, such as polyamines. These molecules are metabolic byproducts that act as infochemicals and modulate bacterial responses toward antibiotics leading to increasing or decreasing resistance levels. Expert opinion: The non-genetic mechanisms of antibiotic response modulation and communication discussed in this review should reorient our thinking of the mechanisms of intrinsic resistance to antibiotics and its spread across bacterial cell populations. The identification of chemical signals mediating increased intrinsic antibiotic resistance will expose novel critical targets for the development of new antimicrobial strategies.

Survival and persistence of opportunistic Burkholderia species in host cells

Burkholderia are microorganisms that have a unique ability to adapt and survive in many different environments. They can also serve as biopesticides and be used for the biodegradation of organic compounds. Usually harmless while living in the soil, these bacteria are opportunistic pathogens of plants and immunocompromised patients, and occasionally infect healthy individuals. Some of the species in this genus can also be utilised as biological weapons. They all possess very large genomes and have two or more circular chromosomes. Their survival and persistence, not only in the environment but also in host cells, offers a remarkable example of bacterial adaptation.

Article 260(2) TFEU: An Effective Judicial Procedure for the Enforcement of Judgments?

Article 260(2) TFEU (ex 228(2) EC) enables the European Court of Justice to enforce compliance with its judgements. This article analyses its use in doing so and questions whether it could be applied more effectively. It commences by highlighting the principally economic and environmental context of the case-law, and by examining the initiatives taken to tackle delays in bringing these cases before the Court. The article then critically evaluates the effectiveness of the financial sanctions available to the Court. In doing so, it aims to fill a gap in present research by looking beyond the procedural measures through which the Court and the Commission operate to examine the practical impact of Article 260(2) itself.

Microneedle-mediated vaccine delivery:harnessing cutaneous immunobiology to improve efficacy

INTRODUCTION: Breaching the skin's stratum corneum barrier raises the possibility of the administration of vaccines, gene vectors, antibodies and even nanoparticles, all of which have at least their initial effect on populations of skin cells. AREAS COVERED: Intradermal vaccine delivery holds enormous potential for improved therapeutic outcomes for patients, particularly those in the developing world. Various vaccine-delivery strategies have been employed, which are discussed in this review. The importance of cutaneous immunobiology on the effect produced by microneedle-mediated intradermal vaccination is also discussed. EXPERT OPINION: Microneedle-mediated vaccines hold enormous potential for patient benefit. However, in order for microneedle vaccine strategies to fulfill their potential, the proportion of an immune response that is due to the local action of delivered vaccines on skin antigen-presenting cells, and what is due to a systemic effect from vaccines reaching the systemic circulation, must be determined. Moreover, industry will need to invest significantly in new equipment and instrumentation in order to mass-produce microneedle vaccines consistently. Finally, microneedles will need to demonstrate consistent dose delivery across patient groups and match this to reliable immune responses before they will replace tried-and-tested needle-and-syringe-based approaches.

Analgesics:a comparison of therapeutic knowledge and inter-professional liaison between general practitioners and community pharmacists

The aim of this study was to ascertain general practitioners' (GPs') and pharmacists' knowledge of analgesics, to establish professional opinion on their use, and to assess the extent of pharmacist input into the prescribing of analgesics. Pharmacists displayed a better knowledge of analgesics than their colleagues in general practice, but had little input into the prescribing decisions made by GPs. Pharmacists' knowledge is not being put to best use in contributing to the preparation of practice formularies, and links between these two health professional groups need to be developed further.
