Background: High volume upper gastrointestinal cancer hospitals demonstrate improved postoperative mortality rates, but the impact on survival is unclear. This population-based cohort study explores the effect of hospital volume on survival following upper gastrointestinal cancer surgery.
Patients And Methods: This study used a population-based cohort of 3866 patients who underwent surgery for oesophageal or gastric cancer between 1998 and 2008 with follow-up until December 2008.
Results: Hospital volume ranged from 1 to 68 cases/year. Overall, 5-year survival was 27%. Increasing age and advanced stage of disease were independently correlated with shorter survival. High hospital volume was significantly and independently correlated with improved 30-day mortality postoperatively (P<0.001), but not with survival beyond 30 days.
Conclusion: The correlation between hospital volume and improved 30-day mortality following oesophageal and gastric cancer surgery supports the centralisation of upper gastrointestinal cancer surgery services. The low survival in both high and low volume hospitals beyond 30 days highlights the need for increasing earlier diagnosis and optimising approaches to radical treatment.

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.

Background: Coronary computed tomography angiography (CCTA) is emerging as a valuable tool for noninvasive surveillance of cardiac allograft vasculopathy (CAV) in patients with heart transplant (HTx). We assessed the diagnostic performance of a comprehensive CCTA-based approach compared with the invasive reference, which includes invasive coronary angiography, intravascular ultrasound, and fractional flow reserve, for detecting CAV.
Methods: This was a multicenter prospective study including 37 patients with HTx who underwent CCTA, invasive coronary angiography, intravascular ultrasound, and fractional flow reserve.

Introduction: The diagnostic accuracy of gastric ultrasound in children has not been assessed thoroughly. We aimed to determine the sensitivity and specificity in children of a qualitative ultrasound examination of the gastric antrum in the supine 45° semi-recumbent position and a clinical algorithm for detecting a gastric fluid volume > 1.25 ml.

Introduction Acute appendicitis is a common surgical emergency that requires a timely and accurate diagnosis to prevent complications. Several laboratory markers have been assessed to improve the diagnostic accuracy of acute appendicitis, including C-reactive protein (CRP), white blood cell (WBC) count, and cytokines like interleukins and tumor necrosis factor-alpha. One less commonly used but potentially valuable marker is the mean platelet volume (MPV), which indicates the size of circulating platelets and has the potential to serve as a biomarker for inflammatory conditions.
