Article Synopsis
  • Simulation is the preferred method for teaching trauma management, with current exploration into virtual and augmented reality as alternative techniques.
  • A systematic search yielded 3815 studies, with 13 ultimately included, showing that while VR is positively received by users, objective assessment is needed.
  • VR is beneficial for training in trauma scenarios, but it won't replace traditional simulation soon; further research with larger groups is required for effective integration into medical education.

Introduction: Hospital-acquired thrombosis (HAT) is defined as any venous thromboembolism (VTE)-related event during a hospital admission or occurring up to 90 days post discharge, and is associated with significant morbidity, mortality and healthcare-associated costs. Although surgery is an established risk factor for VTE, operations with a short hospital stay (<48 hours) and that permit early ambulation are associated with a low risk of VTE. Many patients undergoing short-stay surgical procedures and who are at low risk of VTE are treated with graduated compression stockings (GCS).

Background: Medical therapy for stroke prevention has improved significantly over the past 30 years. Recent analyses of medically treated cohorts have suggested that early rates of stroke may have reduced, and reports of the safety of carotid surgery have also shown improvements. Since the effectiveness of carotid surgery versus medical therapy was established in the 1990s, there is an urgent need to evaluate whether surgery remains cost-effective in the UK.

Chronic lower limb wounds can be described as having the inability to progress through stages of wound healing. Although 80% of lower limb wounds develop as a result of venous insufficiency, other causes include arterial disease and diabetes. In addition to the sustained impact on quality of life, the chronicity of lower limb wounds presents a significant financial burden to healthcare systems.

Diabetic neuropathy (DN) is a common complication of diabetes that is becoming an increasing concern as the prevalence of diabetes rapidly rises. There are several types of DN, but the most prevalent and studied type is distal symmetrical polyneuropathy, which is the focus of this review and is simply referred to as DN. It can lead to a wide range of sensorimotor and psychosocial symptoms and is a major risk factor for diabetic foot ulceration and Charcot neuropathic osteoarthropathy, which are associated with high rates of lower limb amputation and mortality.

Distal symmetrical polyneuropathy (DSPN) is a serious complication of diabetes associated with significant disability and mortality. Although more than 50% of people with diabetes develop DSPN, its pathogenesis is still relatively unknown. This lack of understanding has limited the development of novel disease-modifying therapies and left the reasons for failed therapies uncertain, which is critical given that current management strategies often fail to achieve long-term efficacy.

Carotid artery stenosis causes significant morbidity and mortality accounting for approximately 8% of all ischaemic strokes. Carotid artery stenting (CAS) offers an endovascular alternative to carotid endarterectomy (CEA), suggested as a viable option in those deemed high-risk for open CEA due to comorbidities or operative technical considerations. A number of large randomised-controlled trials (RCTs) and meta-analysis comparing CAS CEA in unselected patient populations support the conclusion that CAS is associated with a higher risk of stroke and CEA is associated with a higher risk of myocardial infraction.

Venous leg ulceration (VLU) is predominantly managed in primary care by district nurses, however much of the research takes place in secondary care. This study aimed to identify to what extent nurses are involved in publishing VLU research and to ascertain how much VLU research is conducted in primary care. Three searches of literature published between 2015 and 2020 were undertaken, reviewing VLU publications on interventions, quality of life and qualitative research.

Background: Chronic exertional compartment syndrome (CECS) is an overuse injury typically seen in young and athletic patients. The five cardinal symptoms are pain, tightness, cramping, weakness, and paresthesia. These classically occur during exertion and disappear with cessation of the activity, with no permanent damage to tissues within the compartment; nonetheless, CECS presents a significant functional impairment to those affected.

New oral anticoagulants (NOACs) are likely to have a major impact in the next few years, changing clinical practice of anticoagulation therapy. Evidence on its efficacy and superiority to vitamin K antagonists (VKAs) in treating non-cancer patients have been reported in a few clinical trials. However, patients with cancer are complicated by the prothrombotic nature of the disease, need for potentially invasive surgery and interventions, and altered drug handling.
