The University of Oxford's United Kingdom Prospective Diabetes Study (UKPDS) was a landmark 30-year clinical trial, reported in over 80 academic research papers between 1983 and 2008. It showed beyond doubt that diabetic complications, previously thought to be inevitable consequences of the condition, could be delayed or prevented by improved treatment from the time of diagnosis. These findings have had a profound influence on the management of type 2 diabetes, clinical guidelines, and standards of care, and have reduced diabetes-related complications worldwide, lowering the incidence of blindness, kidney failure, amputation, heart attack and stroke.
An approach was developed that allowed the design of food items to facilitate psychological functioning: the key insight was that food items that slowly and continuously release glucose have a beneficial impact on mood and cognition. The work has impacted on public policy and is used, for example, to justify recommendations made by the European Food Information Council and the US Department of Agriculture and Food. Globally the findings have stimulated significant interest from food and ingredient manufacturers as they can reformulate food items to make claims about mood and cognitive functioning. This is reflected in the funding received from multi-national corporations, based in six different countries, to exploit the key research findings for the development of novel food formulations. In one instance a patent was established.
Research conducted at King's College London into the mechanisms underlying hypoglycaemia unawareness in type 1 diabetes mellitus (T1DM) and novel technology for reducing the risk of hypoglycaemia has led directly to innovative changes in the management of diabetes. These include UK and worldwide development and dissemination of the government-recommended `Dose Adjustment for Normal Eating' (DAFNE) programme and on-going development of continuous subcutaneous insulin infusion (pump) therapy, now used by over 18,500 people with T1DM in the UK.
DAFNE (Dose Adjustment for Normal Eating) is a structured training programme in Type I diabetes self-management whose development was led by researchers at the University of Sheffield. As a direct result of these research findings, and the demonstration of improved outcomes, there has been a change in the approach to management of Type I diabetes from hospital based, doctor/nurse centric care to patient centred self-management. The Department of Health now mandates structured training in England and Wales, with DAFNE courses provided in a third of UK centres.
(1) Enhancing the awareness of (i) women of childbearing age suffering from epilepsy and prescribed new and/or older generation AEDs, and (ii) their healthcare professionals. Empowering both to make informed decisions through evidence-based practice that will reduce/prevent the risk of harm to unborn children potentially exposed to AEDs in early pregnancy.
(2) A change in the process by which GlaxoSmithKline (GSK) practices post-marketing epidemiological surveillance of the new generation AED `lamotrigine' in pregnancy.
(3) Benefit to the methodological practice of other researchers in Europe involved with AEDs and epidemiological surveillance
(4) Contribution to building European system for reproductive safety evaluation
Metformin is now the most prescribed medication for type 2 diabetes worldwide. Pre - 1990 it received trivial use and was on the verge of withdrawal. Research at Aston (1993 - 1996) generated a new appreciation of its mechanisms of action and therapeutic potential. Aston research was reinforced with a concerted education programme for healthcare professionals, including high-profile reviews and treatment guidelines. We claim impact on health & welfare and health practitioners as Aston research has provided a foundation for improved care of type 2 diabetes patients on a global scale.
Around 2.5 million people in the UK have Type 2 diabetes, with many more in a pre-diabetic state, Both conditions are hard to detect and frequently remain undiagnosed and untreated for years. The cost burden to the NHS of eventual treatment is estimated at £10 billion; 80% of which is spent on complications that are, with good care, avoidable. Targeted diabetes prevention programmes could aid in prevalence reduction and associated costs. Leicester's Diabetes Research Centre has developed two risk scores, both suitable for use with an ethnically diverse UK population, to detect these conditions: a self-assessment questionnaire and a general practice database tool. Recommended by NICE, they have been used successfully in varied settings. Since July 2011, around 260,000 people have completed the self-assessment score online and more than 40,000 through other means.
The University of Southampton's lifecourse cohort studies have led to a paradigm shift in the medical approach to obesity and non-communicable diseases. Research linking maternal pre-conception and early years nutrition with health outcomes for later life has directly influenced public healthcare policy at international (United Nations), national (Scientific Advisory Committee on Nutrition) and local (Southampton City) levels. Dissemination through medical practice and Southampton-designed public education programmes such as LifeLab means this research has already led to health benefits for tens of thousands of people, providing them with the information and tools to help prevent themselves and their children from succumbing to a non-communicable disease.
The Boutelle team has developed a biosensor that uses rapid-sampling microdialysis (rsMD) to detect ischaemia (restricted blood supply to tissue) during surgery and intensive care. The rsMD biosensor is implanted into tissue at risk and provides a real-time readout of chemical markers of metabolism. By 2009, technical improvements researched in the Department of Bioengineering had made the system suitable for routine clinical use. The system has reduced morbidity and mortality by alerting the surgical team to otherwise undetected ischaemia. It has been used by an international consortium of clinical centres to help decide treatment in approximately 100 patients with brain injury. More recently it was adopted by a Portsmouth hospital to monitor cancer patients undergoing reconstruction of the face and jaw; the biosensor detected a failure of perfusion in transplanted tissue in two of the first ten patients, prompting the surgical team to remove otherwise undetected blood clots that could have led to death from septicaemia.
Over the past ten years, the prescription of cholesterol-lowering statins has soared and they are now the most prescribed drugs in the UK and the US. However, this has raised concerns about inappropriate prescribing. University of Glasgow research has been pivotal in addressing this issue and has triggered revision of major international guidelines to stratify patients in the general population for statin therapy and guide statin use in the rheumatoid arthritis patient population. The identification of a statin-associated risk for diabetes prompted the European Medicines Agency and the US Food & Drug Administration to revise safety labelling for all classes of statins. This risk is now communicated to the 27 million patients in the UK and US who are prescribed statins.
