Visualising London

This research investigates how photographs can be analysed to extract meaning. Two methodologies, visual anthropology and social semiotics, are used to analyse a collection of images and accompanying texts generated by a group of first year tourism students in London. Photographs are categorised into subject areas including iconic buildings, street scenes, people and analysed according to how they relate to the photographers’ characteristics, such as age and nationality. A group of images of Big Ben are then analysed using a social semiotics approach, considering both compositional and contextual information to extract meanings. Results and techniques are then contrasted and compared, noting how the complexity of the image makers’ experience of the city they are documenting lead to their images having multi-layered meanings, and that combining analytic methods can fruitfully reveal a range of these meanings.

Telaprevir or boceprevir based therapy for chronic hepatitis C infection: Development of resistance-associated variants in treatment failure

The use of triple-therapy, pegylated-interferon, ribavirin and either of the first generation hepatitis C virus (HCV) protease inhibitors telaprevir or boceprevir, is the new standard of care for treating genotype 1 chronic HCV. Clinical trials have shown response rates of around 70–80%, but there is limited data from the use of this combination outside this setting. Through an expanded access programme, we treated 59 patients, treatment naïve and experienced, with triple therapy. Baseline factors predicting treatment response or failure during triple therapy phase were identified in 58 patients. Thirty seven (63.8%) of 58 patients had undetectable HCV RNA 12 weeks after the end of treatment. Genotype 1a (p = 0.053), null-response to previous treatment (p = 0.034), the rate of viral load decline after 12 weeks of previous interferon-based treatment (p = 0.033) were all associated with triple-therapy failure. The most common cause of on-treatment failure for telaprevir-based regimens was the development of resistance-associated variants (RAVs) at amino acids 36 and/or 155 of HCV protease (p = 0.027) whereas in boceprevir-based regimens mutations at amino acid 54 were significant (p = 0.015). SVR12 rates approaching 64% were achieved using triple therapy outside the clinical trial setting, in a patient cohort that included cirrhotics.

Foundation degrees in biomedical science: the student experience

The first cohort of students on a University of Westminster foundation degree completed the course recently. Here, Chrystalla Ferrier, Kelly Brookwell and Paul Quinn employ some reflective practice.
