Translation of PET radiotracers for cancer imaging: recommendations from the National Cancer Imaging Translational Accelerator (NCITA) consensus meeting.
BMC Med
January 2025
Department of Oncology, University of Oxford, Oxford, UK.
Background: The clinical translation of positron emission tomography (PET) radiotracers for cancer management presents complex challenges. We have developed consensus-based recommendations for preclinical and clinical assessment of novel and established radiotracers, applied to image different cancer types, to improve the standardisation of translational methodologies and accelerate clinical implementation.
Methods: A consensus process was developed using the RAND/UCLA Appropriateness Method (RAM) to gather insights from a multidisciplinary panel of 38 key stakeholders on the appropriateness of preclinical and clinical methodologies and stakeholder engagement for PET radiotracer translation.
Large simple randomized controlled trials-from drugs to medical devices: lessons from recent experience.
Trials
January 2025
Department of Cardiology, University Hospital of Wales, Cardiff, UK.
Randomized controlled trials (RCTs) are the cornerstone of modern evidence-based medicine. They are considered essential to establish definitive evidence of efficacy and safety for new drugs, and whenever possible they should also be the preferred method for investigating new high-risk medical devices. Well-designed studies robustly inform clinical practice guidelines and decision-making, but administrative obstacles have made it increasingly difficult to conduct informative RCTs.

Phys Med Biol
January 2025
Joint Department of Physics, The Institute of Cancer Research and The Royal Marsden NHS Foundation Trust, Downs Road, Sutton, London, Surrey, SM2 5PT, UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND.
This study aims to develop and evaluate a fast and robust deep learningbased auto-segmentation approach for organs at risk in MRI-guided radiotherapy of pancreatic cancer to overcome the problems of time-intensive manual contouring in online adaptive workflows. The research focuses on implementing novel data augmentation techniques to address the challenges posed by limited datasets. Approach: This study was conducted in two phases.

Obes Surg
January 2025
Department of Surgery and Transplantation, University Hospital of Zurich, University of Zurich, Zurich, Switzerland.
Background: Roux-en-Y gastric bypass may present long-term complications that require revisional surgery or even reversal to normal anatomy. Data on the indications, surgical technique, and outcomes of RYGB reversal remain scarce.
Methods: We identified 48 cases of RYGB reversals with complete 90-day follow-up within a multi-centric international retrospective database of elective secondary bariatric surgery.
PLA2R autoantibodies, a multifaceted biomarker in nephrotic syndrome and membranous nephropathy.
Nephrol Dial Transplant
January 2025
Manchester Institute of Nephrology and Transplantation, Manchester University NHS Foundation Trust, Manchester, UK.
Background And Hypothesis: The PLA2R antibody test is a valuable first-line diagnostic tool for primary membranous nephropathy (MN), helping to identify PLA2R-related MN and potentially eliminating the need for a kidney biopsy in some individuals. By reducing the reliance on biopsies, the test streamlines diagnosis and improves patient care. However, determining the optimal PLA2R measurement method and cut-off is critical to maximising the benefits of the test and minimising any harms.
