Public involvement in health research: a case study of one NHS project over 5 years
Background: Public involvement, both in the National Health Service (NHS) and in clinical research, is promoted as an important democratic principle. The declared aims are to reduce professional autocracy and allow a broader ownership of the research agenda; also to improve the design of, and recruitment and retention of patients to, clinical studies. There have been a number of national initiatives in the UK to improve public input to clinical research activities, but very few reports of effective and sustainable partnerships over time. This study reports the evaluation of one example, which is embedded in the NHS and university partnerships in the Norfolk area of England. Objectives Evaluate: • Putting principles into practice of public involvement in research over a 5 year period for one specific project (Patient and Public Involvement in Research). • How the model contributes to, and impacts upon, all stages of the research process. • Attitudes of the research community and lay volunteers to their mutual experiences of public involvement. • Key factors and strengths of this project, and areas for improvement. Methods: A mixed methods approach related to the 5 years from start of 2003 to end of 2007. This used descriptive statistics of volunteer activity, interviews with key stakeholders (13), questionnaires (53% response rate), and focus group with 10 volunteers to explore emergent themes. We analysed findings using a policy framework approach. Results: About 47 of the original 55 volunteers remained on the panel after 5 years. All have undertaken training, 38% have been involved in the full range of research activities offered, and 75% have attended at least one research project meeting. Some are active in governance, ethics, and advisory committees. Both the research community and the volunteers are very positive about the project. The researchers find it provides well prepared personnel, and gives a speedy and efficient way of fulfilling the expectations of funders for lay input. The volunteers find it gives them important opportunities to influence the quality of research and thus support improvements in patient care. Areas for improvement include increasing social diversity among the volunteers, and improving feedback on input from volunteers, without which volunteers tend to lose confidence and motivation. Conclusion: Long-term sustainable and valuable public input to research is possible. Key factors are committing resources, embedding the service in the infrastructure of a research consortium, and ongoing responsiveness by NHS staff and researchers. Additional activity to recruit and support access may be needed to attract people from a broad range of sociodemographic backgrounds. Some volunteers want more involvement than this model currently offers

Staphylococcus aureus MnhF mediates cholate efflux and facilitates survival under human colonic conditions
Resistance to the innate defences of the intestine is crucial for the survival and carriage of Staphylococcus aureus, a common coloniser of the human gut. Bile salts produced by the liver and secreted into the intestines are one such group of molecules with potent anti-microbial activity. The mechanisms by which S. aureus is able to resist such defences in order to colonize and survive in the human gut are unknown. Here we show that mnhF confers resistance to bile salts, which can be abrogated by efflux pump inhibitors. MnhF mediates efflux of radiolabelled cholic acid in both S. aureus and when heterologously expressed in Escherichia coli, rendering them resistant. Deletion of mnhF attenuated survival of S. aureus in an anaerobic three stage continuous culture model of the human colon (gut model), which represent different anatomical areas of the large intestine

Supervision by videoconference with rural probationary psychologists
Videoconference networks afford access to education and supervision for health professionals in rural areas. Yet the assumed equivalence between videoconferencing and face-to-face communication remains largely untested. Evidence for the unique aspects of videoconferenced communication (Jerome and Zaylor 2000) does suggest consequences for traditional supervision methods, particularly the core components of teaching and a working alliance. This study explored the experience of videoconferenced supervision with a supervision model (Bernard 1979, 1997) together with power and involvement. Semi-structured interviews were conducted with 26 psychologists. Qualitative content analysis confirmed the roles and content areas defined by Bernard’s supervision model but with some interesting addition and modification. Formal communication increased as did a power discrepancy between trainee and supervisor. Influences upon involvement were more complex; social presence was degraded yet some trainees felt freer to divulge emotional content. The findings affirm some unique features to videoconferenced supervision and validate a framework for its further exploration

Prebiotic supplementation of In Vitro fecal fermentations inhibits proteolysis by gut bacteria, and host diet shapes gut bacterial metabolism and response to intervention
Metabolism of protein by gut bacteria is potentially detrimental due to the production of toxic metabolites, such as ammonia, amines, p-cresol, and indole. The consumption of prebiotic carbohydrates results in specific changes in the composition and/or activity of the microbiota that may confer benefits to host well-being and health. Here, we have studied the impact of prebiotics on proteolysis within the gut in vitro. Anaerobic stirred batch cultures were inoculated with feces from omnivores (n = 3) and vegetarians (n = 3) and four protein sources (casein, meat, mycoprotein, and soy protein) with and without supplementation by an oligofructose-enriched inulin. Bacterial counts and concentrations of short-chain fatty acids (SCFA), ammonia, phenol, indole, and p-cresol were monitored during fermentation. Addition of the fructan prebiotic Synergy1 increased levels of bifidobacteria (P = 0.000019 and 0.000013 for omnivores and vegetarians, respectively). Branched-chain fatty acids (BCFA) were significantly lower in fermenters with vegetarians’ feces (P = 0.004), reduced further by prebiotic treatment. Ammonia production was lower with Synergy1. Bacterial adaptation to different dietary protein sources was observed through different patterns of ammonia production between vegetarians and omnivores. In volunteer samples with high baseline levels of phenol, indole, p-cresol, and skatole, Synergy1 fermentation led to a reduction of these compounds
