Background: High estimates of preventable death rates have renewed the impetus for national regionalization of trauma care. Institution of a specialist multidisciplinary trauma service and performance improvement programme was hypothesized to have resulted in improved outcomes for severely injured patients.
Methods: This was a comparative analysis of data from the Royal London Hospital (RLH) trauma registry and Trauma Audit and Research Network (England and Wales), 2000-2005. Preventable mortality was evaluated by prospective analysis of the RLH performance improvement programme.
Results: Mortality from critical injury at the RLH was 48 per cent lower in 2005 than 2000 (17.9 versus 34.2 per cent; P = 0.001). Overall mortality rates were unchanged for acute hospitals (4.3 versus 4.4 per cent) and other multispecialty hospitals (8.7 versus 7.3 per cent). Secondary transfer mortality in critically injured patients was 53 per cent lower in the regional network than the national average (5.2 versus 11.0 per cent; P = 0.001). Preventable death rates fell from 9 to 2 per cent (P = 0.040) and significant gains were made in critical care and ward bed utilization.
Conclusion: Institution of a specialist trauma service and performance improvement programme was associated with significant improvements in outcomes that exceeded national variations.

Background: Colorectal cancer (CRC) is the third most common cancer in the United Kingdom and the second largest cause of cancer death.
Aim: To develop and validate a model using available information at the time of faecal immunochemical testing (FIT) in primary care to improve selection of symptomatic patients for CRC investigations.
Methods: We included all adults (≥ 18 years) referred to Nottingham University Hospitals NHS Trust between 2018 and 2022 with symptoms of suspected CRC who had a FIT.

Annually, thousands of individuals suffer from skin injuries resulting from trauma, surgeries, or diabetes. Inadequate wound treatment can delay healing and increase the risk of severe infections. In this context, a promising synthetic polymer with potent antimicrobial properties, Poly{2-[(methacryloyloxy)ethyl]trimethylammonium chloride} (PMETAC), is synthesized and crosslinked with N,N'-Methylenebis(acrylamide) (BIS) in the presence of Chitosan (CH), a natural, biocompatible polysaccharide that promotes cell regeneration and provides additional beneficial properties.

Surgical treatment of congenital pseudarthrosis of the Tibia in children: CPAM-LRC consensus and guidelines.

Department of Orthopedics, Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China.
Purpose: Congenital pseudarthrosis of the tibia (CPT) is a rare condition typically manifesting within the first decade of life. The primary objectives of surgical intervention for CPT include achieving long-term bony union of the tibia, preventing or minimizing limb length discrepancies (LLD), avoiding mechanical axis deviations of the tibia and adjacent joints, and preventing refracture. This study aims to conduct a systematic review of current treatment methods for CPT to determine the most effective non-surgical and surgical management strategies for pediatric patients with this condition.
