• PM-344 Capstone Project

  The aim of this module is to provide a capstone experience to students¿ learning, through participating in their own enquiry-based research project. The project may be laboratory or non-laboratory based, but it will always involve a research question that is drawn from the literature, and focused on a topic relevant to the life sciences. It will ask a novel research question and involve the critical analysis of research findings. Students will refine their oral and written communication skills to a graduate level through creating an introductory presentation on the project background, and a written dissertation and oral presentation on their research conclusions.

• PM-356 The Sweet Sickness: Advances in Diabetes and Related Disorders

  7% of the population suffers from diabetes. This prevalence is set to rise with an ageing population and increasing rates of obesity. The problem is especially acute in Wales, where over half the adult population is obese. According to Diabetes Wales, there are 177,000 people in the country living with diabetes, and estimates suggest a further 70,000 people have diabetes but are either unaware or have no confirmed diagnosis. If current trends continue, by 2025, it is estimated that 300,000 people in Wales will have diabetes. This module will provide an overview of diabetes and the public health challenges it presents. The world-leading research of the Diabetes Research Group, located here at Swansea University Medical School, will be a particular focus with basic, clinical, epidemiological, social care and health services research discussed.

• PMCB01 Clinical Biochemistry for Biomedical Scientists

• PMDM01 Diabetes Basics

  This module aims to introduce the basics of diabetes, a condition where there are an estimated 4.5 million people living with the disease in the UK alone, and a further 1.1 million that are undiagnosed. It will detail prevalence and pathophysiology, nutrition and self-care, and a basic understanding of associated complications. It aims to develop the students¿ knowledge of the many key factors that contribute to this enormous healthcare issue. The module will be delivered online via distance learning, with online assessments.

• PMDM02 Diabetes Management I

  This module is delivered primarily as a 5-day residential that aims to develop the students¿ knowledge of the available pharmaceutical treatments for diabetes. It will explore all aspects of current pharmaceutical regimes from oral medications through injectables to basic pump technologies. This will enable the students to not only have the opportunity to see and handle these pharmaceuticals, but also appreciate the wider context of medication planning and progression of the disease. The module will be delivered primarily on campus (5-day residential) with extra online content, and both in situ and online assessments.

• PMDM03 Diabetes Events

  This module will aim to explore and give a basic underpinning knowledge of events that can result from or affect diabetes care. This will include hypo- and hyperglycemia, illness and pregnancy, demonstrating causes of disruption and the courses of action required to ensure continuous diabetes management throughout. The module will be delivered online via distance learning, with online assessments.

• PMDM04 Diabetes Complications

  This module will detail and further enhance the students¿ knowledge of the micro- and macrovascular complications that can arise as a result of diabetes, including retinopathy, kidney damage, cardiovascular disease and stroke. It will highlight the associated risk, symptoms, progression and possible treatments with regard to these conditions. The module will be delivered online via distance learning, with online assessments.

• PMDM05 Diabetes Management II

  This module is delivered primarily as a 5-day residential that aims to enhance the students¿ knowledge of the advanced treatments for diabetes. It will explore continuous/flash glucose monitoring and all aspects of pump technologies and pregnancy usage. This will enable the students to see and handle these new technologies that are not necessarily common place in clinics, and appreciate the concept of treatment planning and progression using these devices. The module will be delivered primarily on campus (5-day residential) with extra online content, and both in situ and online assessments.

• PMDM06 Diabetes Situations

  This module will investigate the situations in which there are a need for specialised diabetes planning, treatment and care. It will highlight the areas of care that require specific and considered practice such as inpatient care, elderly/infirm patients and care in the community. The module will be delivered online via distance learning, with online assessments.

• PMDM07 Dissertation (Research/Audit)

  This module will comprise of a written dissertation of either a research project or audit. The piece will need to demonstrate independent learning and critical thinking to explore and add to the evidence base for a topic of relevance to their area of interest within the field of diabetes.

• PMDM08 Work Based Portfolio

  This module will allow students to review, appraise and evaluate the application of the knowledge gained throughout the programme within their own professional work environment by providing a portfolio of evidence that is supported by a reflective commentary.
