Laboratory studies suggest that the postischaemic gut serves as a priming bed for circulating neutrophils that provoke multiple organ failure. Platelet-activating factor, generated by phospholipase A2, appears to be active in priming neutrophils in the gut. Interleukin-6 also appears to be elaborated by the postischaemic gut, but may be even more important in distant organs via promoting neutrophil-mediated organ dysfunction.

Cancer incidence and competing mortality risk following 15 presenting symptoms in primary care: a population-based cohort study using electronic healthcare records.
BMJ Oncol
November 2024
Department of Behavioural Science and Health, Institute of Epidemiology and Healthcare, University College London, London, UK.
Objectives: Assessment of age, sex and smoking-specific risk of cancer diagnosis and non-cancer mortality following primary care consultation for 15 new-onset symptoms.
Methods And Analysis: Data on patients aged 30-99 in 2007-2017 were extracted from a UK primary care database (CPRD Gold), comprising a randomly selected reference group and a symptomatic cohort of patients presenting with one of 15 new onset symptoms (abdominal pain, abdominal bloating, rectal bleed, change in bowel habit, dyspepsia, dysphagia, dyspnoea, haemoptysis, haematuria, fatigue, night sweats, weight loss, jaundice, breast lump and post-menopausal bleed).Time-to-event models were used to estimate outcome-specific hazards for site-specific cancer diagnosis and non-cancer mortality and to estimate cumulative incidence up to 12 months following index consultation.

Bone remodeling is a continuous cyclic process that maintains and regulates bone structure and strength. The disturbance of bone remodeling leads to a series of bone metabolic diseases. Recent studies have shown that citrate, an intermediate metabolite of the tricarboxylic acid (TCA) cycle, plays an important role in bone remodeling.

Severe esophageal strictures resulting from chemoradiotherapy pose persistent therapeutic challenges despite the availability of treatments such as endoscopic balloon dilation and medications. Hyperbaric oxygen therapy (HBOT) has emerged as a promising treatment option for refractory radiation-induced injury to several organs. Herein, we present the case of a 79-year-old male patient with refractory radiation-induced ulcerative esophageal strictures after chemoradiotherapy.

Background: Patients with multiple organ metastases from hepatic alveolar echinococcosis have a high mortality rate. However, predictors of multi-organ metastasis have not been identified. We aimed to develop a nomogram that predicts multi-organ metastasis in patients with hepatic alveolar echinococcosis.
