BackgroundThe Framework Method is becoming an increasingly popular approach to the management and analysis of qualitative data in health research. However, there is confusion about its potential application and limitations.DiscussionThe article discusses when it is appropriate to adopt the Framework Method and explains the procedure for using it in multi-disciplinary health research teams, or those that involve clinicians, patients and lay people. The stages of the method are illustrated using examples from a published study.SummaryUsed effectively, with the leadership of an experienced qualitative researcher, the Framework Method is a systematic and flexible approach to analysing qualitative data and is appropriate for use in research teams even where not all members have previous experience of conducting qualitative research.

DrugBank (www.drugbank.ca) is a web-enabled database containing comprehensive molecular information about drugs, their mechanisms, their interactions and their targets. First described in 2006, DrugBank has continued to evolve over the past 12 years in response to marked improvements to web standards and changing needs for drug research and development. This year’s update, DrugBank 5.0, represents the most significant upgrade to the database in more than 10 years. In many cases, existing data content has grown by 100% or more over the last update. For instance, the total number of investigational drugs in the database has grown by almost 300%, the number of drug-drug interactions has grown by nearly 600% and the number of SNP-associated drug effects has grown more than 3000%. Significant improvements have been made to the quantity, quality and consistency of drug indications, drug binding data as well as drug-drug and drug-food interactions. A great deal of brand new data have also been added to DrugBank 5.0. This includes information on the influence of hundreds of drugs on metabolite levels (pharmacometabolomics), gene expression levels (pharmacotranscriptomics) and protein expression levels (pharmacoprotoemics). New data have also been added on the status of hundreds of new drug clinical trials and existing drug repurposing trials. Many other important improvements in the content, interface and performance of the DrugBank website have been made and these should greatly enhance its ease of use, utility and potential applications in many areas of pharmacological research, pharmaceutical science and drug education.

Introduction: Poor access of lesbian, gay, bisexual and transgender (LGBT) people to healthcare providers with clinical and cultural competency contributes to health inequalities between heterosexual/cisgender and LGBT people. This systematic review assesses the effect of educational curricula and training for healthcare students and professionals on LGBT healthcare issues.Methods: Systematic review; the search terms, strategy and process as well as eligibility criteria were predefined and registered prospectively on PROSPERO. A systematic search of electronic databases was undertaken. Screening for eligible studies and data extraction were done in duplicate. All the eligible studies were assessed for risk of bias. The outcome of interest was a change in participants’ knowledge, attitude and or practice.Results: Out of 1171 papers identified, 16 publications reporting 15 studies were included in the review. Three were non-randomized controlled studies and 12 had a pre/post-design; two had qualitative components. Bias was reported in the selection of participants and confounding. Risk reported was moderate/mild. Most studies were from the USA, the topics revolved around key terms and terminology, stigma and discrimination, sexuality and sexual dysfunction, sexual history taking, LGBT-specific health and health disparities. Time allotted for training ranged from 1 to 42 hours, the involvement of LGBT people was minimal. The only intervention in sub-Saharan Africa focused exclusively on men who have sex with men. All the studies reported statistically significant improvement in knowledge, attitude and/or practice post-training. Two main themes were identified from the qualitative studies: the process of changing values and attitudes to be more LGBT inclusive, and the constraints to the application of new values in practice.Conclusions: Training of healthcare providers will provide information and improve skills of healthcare providers which may lead to improved quality of healthcare for LGBT people. This review reports short-term improvement in knowledge, attitudes and practice of healthcare students and professionals with regards to sexual and LGBT-specific healthcare. However, a unified conceptual model for training in-terms of duration, content and training methodology was lacking.

Complementary and alternative medicine (CAM) and traditional medicine (TM) are important social phenomena. This article reviews the sociological literature on the topic. First, it addresses the question of terminology, arguing that the naming process is a glimpse into the complexities of power and history that characterize the field. Second, focusing on the last 15 years of scholarship, it considers how sociological research on users and practitioners of TM/CAM has developed in that time. Third, it addresses two newer strands of work termed here the ‘big picture’ and the ‘big question’. The big picture includes concepts that offer interpretation of what is happening at a societal level to constrain and enable observed patterns of social practice (pluralism, integration, hybridity and activism). The big question, ‘Does it work?’, is one of epistemology and focuses on two developing fields of critical enquiry – first, social critiques of medical science knowledge production and, second, attempts to explain the nature of interventions, i.e. how they work. Finally, the article examines the role of sociology moving forward.

BackgroundThere are now effective drugs to prevent cardiovascular disease and guidelines recommend their use. Patients do not always choose to accept preventive medication at levels of risk reduction recommended in guidelines. The purpose of the study was to identify and explore the attitudes of patients and general practitioners towards preventative medication for cardiovascular disease (CVD) after they have received information about it; to identify implications for practice and prescribing.MethodsQualitative interviews with GPs and patients following presentation of in depth information about CVD risks and the absolute effects of medication. Setting: GP practices in Birmingham, United Kingdom.ResultsIn both populations: wide variation on attitudes to preventative medication; concerns about unnecessary drug taking & side effects; preferring to consider lifestyle changes first. In patient population: whatever their attitudes to medication were, the vast majority explained that they would ultimately do what their GP recommended; there was some misunderstanding of the distinction between curative and preventative medication. A common theme was the degree of trust in their doctors' judgement and recommendations, which contrasted with scepticism of the role of pharmaceutical companies and academics. Scepticism in guidelines was also common among doctors although many nevertheless recommended treatment for their patientsConclusionsA guideline approach to prescribing preventative medication could be against the interests and preferences of the patient. GPs must take extra care to explain what preventative medication is and why it is recommended, attempt to discern preferences and make recommendations balancing these potentially conflicting concerns.

Proteolysis within the lipid bilayer is poorly understood, in particular the regulation of substrate cleavage. Rhomboids are a family of ubiquitous intramembrane serine proteases that harbour a buried active site and are known to cleave transmembrane substrates with broad specificity. In vitro gel and Förster resonance energy transfer (FRET)-based kinetic assays were developed to analyse cleavage of the transmembrane substrate psTatA (TatA from Providencia stuartii). We demonstrate significant differences in catalytic efficiency (kcat/K0.5) values for transmembrane substrate psTatA (TatA from Providencia stuartii) cleavage for three rhomboids: AarA from P. stuartii, ecGlpG from Escherichia coli and hiGlpG from Haemophilus influenzae demonstrating that rhomboids specifically recognize this substrate. Furthermore, binding of psTatA occurs with positive cooperativity. Competitive binding studies reveal an exosite-mediated mode of substrate binding, indicating allostery plays a role in substrate catalysis. We reveal that exosite formation is dependent on the oligomeric state of rhomboids, and when dimers are dissociated, allosteric substrate activation is not observed. We present a novel mechanism for specific substrate cleavage involving several dynamic processes including positive cooperativity and homotropic allostery for this interesting class of intramembrane proteases.

Background. Heart failure is a common long term condition affecting around 900 000 people in the UK and patients commonly present to primary care. The prognosis of patients with a code of heart failure in their primary care record is unknown.Objective. The study sought to determine the overall survival rates for patients with heart failure in a primary care population from the time of diagnosis.Methods. Survival analysis was carried out using UK primary care records from The Health Improvement Network (THIN) between 1 January 1998 and 31 December 2012. Patients age 45 or over with a first diagnostic label of heart failure were matched by age, sex and practice to people without heart failure. Outcome was death in the heart failure and no heart failure cohorts. Kaplan-Meier curves were used to compare survival. Age-specific survival rates at 1, 5 and 10 years were determined for men and women with heart failure. Survival rates by year of diagnosis and case definition were also calculated.Results. During the study period, 54313 patients had a first diagnostic code of heart failure. Overall survival rates for the heart failure group were 81.3% (95%CI 80.9–81.6), 51.5% (95%CI 51.0–52.0) and 29.5% (95%CI 28.9–30.2) at 1, 5 and 10 years respectively and did not change over time.Conclusions. In a primary care population, the survival of patients diagnosed with heart failure did not improved over time. Further research is needed to explain these trends and to find strategies to improve outlook.

A theoretical understanding of why some people with chronic obstructive pulmonary disorder (COPD) experienced 'peace of mind' when a new telehealth service was introduced into a community respiratory service (CRS) is presented in this article. This is based on analysis of in-depth, qualitative, situated interviews with COPD patients who were receiving the service. Telehealth brought peace of mind through two mechanisms: legitimising contact with health professionals and increased patient confidence in the management of their condition. When the home is the primary health space, the introduction of telehealth can modify emotional and bodily experiences to an extent that is significant for people with COPD. The process by which technology can provide 'peace of mind' to people with long term conditions should be taken into account when designing or commissioning a service.
