Objectives: The objective of this study was to model the clinical and economic impact of adapting current clinical practice in the management of patients with chronic obstructive pulmonary disease (COPD) to treatment according to national and international guideline recommendations.

Design: Treatment mapping was undertaken to hypothetically redistribute patients from current clinical practice, representing actual prescribing patterns in the UK, to an alternative recommendation-based treatment scenario, representing prescribing in accordance with either National Institute for Health and Care Excellence (NICE) guidance [NG115] or Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2020 strategy.

Setting: Primary care practices in the UK (1-year time horizon).

Introduction: International guidelines recommend treatment with a sodium-glucose cotransporter-2 (SGLT-2) inhibitor or glucagon-like peptide-1 (GLP-1) receptor agonist for treatment intensification in type 2 diabetes mellitus (T2DM) patients with progression on metformin. In the randomised, controlled, Peptide Innovation for Early Diabetes Treatment (PIONEER) 2 trial, the SGLT-2 inhibitor empagliflozin was compared with the GLP-1 receptor agonist oral semaglutide, in addition to metformin. The aim of the current study was to assess the long-term cost-effectiveness of empagliflozin 25 mg versus oral semaglutide 14 mg, in addition to metformin, for T2DM patients in the UK.

Introduction: Management of phenylketonuria (PKU) is mainly achieved through strict dietary control that aims to limit the intake of phenylalanine (Phe). Adherence to this diet is burdensome due to the need for specially prepared low-Phe meals and regular monitoring of Phe concentrations. A UK cross-sectional study was conducted to identify the personal time and monetary burden associated with aspects of the PKU lifestyle for caregivers of children (aged < 18 years) living with PKU.

This study assessed the cost-effectiveness of Octaplas™ versus fresh frozen plasma (FFP) in patients receiving plasma transfusions in the United States (US). Acute and long-term complications of plasma transfusions were modelled in a decision tree followed by a Markov model, using a healthcare payer perspective. Over a lifetime time horizon, patients receiving Octaplas™ accumulate slightly more life years (0.

Vaccines against viruses need to target dendritic cells (DC) and stimulate mucosal immunity. Most vaccine studies have focussed on monocyte-derived or dermal DC (dDC) but recent evidence suggests that Langerhans cells (LC) may stimulate mucosal immunity more effectively. New chimeric adenovirus vectors expressing fibre protein from group B adenoviruses (rAd5/11), which utilise CD46 rather than the Coxsackie adenovirus receptor (CAR), have been developed as vaccines to improve transduction and overcome problems of pre-existing vector immunity.
