Randomised, placebo-controlled, phase 3 trial of the effect of the omega-3 polyunsaturated fatty acid eicosapentaenoic acid (EPA) on colorectal cancer recurrence and survival after surgery for resectable liver metastases: EPA for Metastasis Trial 2 (EMT2) study protocol.

Introduction: There remains an unmet need for safe and cost-effective adjunctive treatment of advanced colorectal cancer (CRC). The omega-3 polyunsaturated fatty acid eicosapentaenoic acid (EPA) is safe, well-tolerated and has anti-inflammatory as well as antineoplastic properties. A phase 2 randomised trial of preoperative EPA free fatty acid 2 g daily in patients undergoing surgery for CRC liver metastasis showed no difference in the primary endpoint (histological tumour proliferation index) compared with placebo.

Omega-3 polyunsaturated fatty acids: moving towards precision use for prevention and treatment of colorectal cancer.

Data from experimental studies have demonstrated that marine omega-3 polyunsaturated fatty acids (O3FAs) have anti-inflammatory and anticancer properties. In the last decade, large-scale randomised controlled trials of pharmacological delivery of O3FAs and prospective cohort studies of dietary O3FA intake have continued to investigate the relationship between O3FA intake and colorectal cancer (CRC) risk and mortality. Clinical data suggest that O3FAs have differential anti-CRC activity depending on several host factors (including pretreatment blood O3FA level, ethnicity and systemic inflammatory response) and tumour characteristics (including location in the colorectum, histological phenotype (eg, conventional adenoma or serrated polyp) and molecular features (eg, microsatellite instability, cyclooxygenase expression)).

Surveillance Is Important After Surgical Excision of Giant Fibrovascular Polyps of the Esophagus.

Giant fibrovascular polyps of the esophagus are rare benign tumors arising from the cervical esophagus or hypopharynx. Radiologic and endoscopic investigation may struggle to identify a stalk or to delineate the tumor as luminal or submucosal in origin. Excision is advised, although the diagnosis, and therefore the optimal operative approach, may not be apparent until the time of operation.

A liquid chromatography-tandem mass spectrometry method to measure fatty acids in biological samples.

As pre-clinical and clinical research interest in ω-3 polyunsaturated fatty acids (PUFA) increases, so does the need for a fast, accurate and reproducible analytical method to measure fatty acids (FA) in biological samples in order to validate potential prognostic and predictive biomarkers, as well as establishing compliance in ω-3 PUFA intervention trials. We developed a LC-ESI-MS/MS method suitable for high throughput development to measure FAs and validated it in the context of treatment with the ω-3 PUFA eicosapentaenoic acid (EPA). Uniquely we directly compared the LC-ESI-MS/MS method to a GC-MS protocol.

Measurement of red blood cell eicosapentaenoic acid (EPA) levels in a randomised trial of EPA in patients with colorectal cancer liver metastases.

We investigated red blood cell (RBC) PUFA profiles, and the predictive value of RBC EPA content for tumour EPA exposure and clinical outcomes, in the EMT study, a randomised trial of EPA in patients awaiting colorectal cancer (CRC) liver metastasis surgery (Cockbain et al., 2014) [8]. There was a significant increase in RBC EPA in the EPA group (n=43; median intervention 30 days; mean absolute 1.

Changes in plasma chemokine C-C motif ligand 2 levels during treatment with eicosapentaenoic acid predict outcome in patients undergoing surgery for colorectal cancer liver metastasis.

The mechanism of the anti-colorectal cancer (CRC) activity of the omega-3 fatty acid eicosapentaenoic acid (EPA) is not understood. We tested the hypothesis that EPA reduces expression of chemokine C-C motif ligand 2 (CCL2), a pro-inflammatory chemokine with known roles in metastasis.We measured CCL2 in clinical samples from a randomized trial of EPA in patients undergoing liver surgery for CRC liver metastasis (LM) and preclinical models.

Anticolorectal cancer activity of the omega-3 polyunsaturated fatty acid eicosapentaenoic acid.

Background: Oral administration of the omega-3 fatty acid eicosapentaenoic acid (EPA), as the free fatty acid (FFA), leads to EPA incorporation into, and reduced growth of, experimental colorectal cancer liver metastases (CRCLM).

Design: We performed a Phase II double-blind, randomised, placebo-controlled trial of EPA-FFA 2 g daily in patients undergoing liver resection surgery for CRCLM. The patients took EPA-FFA (n=43) or placebo (n=45) prior to surgery.

Increased morbidity in overweight and obese liver transplant recipients: a single-center experience of 1325 patients from the United Kingdom.

Obesity levels in the United Kingdom have risen over the years. Studies from the United States and elsewhere have reported variable outcomes for obese liver transplant recipients in terms of post-liver transplant morbidity, mortality, and graft survival. This study was designed to analyze the impact of the body mass index (BMI) on outcomes following adult liver transplantation.

Transplantation of solid organs procured from influenza A H1N1 infected donors.

Following the influenza A H1N1 (swine flu) pandemic, there remains little evidence informing the safety of transplanting organs from donors suspected or diagnosed with H1N1. Limited guidelines from the major transplant societies leave the use of such organs at the discretion of individual transplant centres, and practice varies considerably both nationally and internationally. We present the largest published series of outcome following transplantation of organs from H1N1 positive donors and demonstrate that these organs can be transplanted safely and with good short-term outcome.

Spontaneous resolution of pulmonary nodules in autoimmune pancreatitis.

Context: Autoimmune pancreatitis is a rare benign disorder that can be confused with pancreatic cancer and the treatment pathway differs dramatically.

Case Report: We present a unique case of pulmonary nodules associated with autoimmune pancreatitis, that was initially confused for pancreatic cancer which resolved spontaneously. Herein we describe the case and subsequent management and discuss the ever increasing incidence of autoimmune pancreatitis.

Index admission laparoscopic cholecystectomy for patients with acute biliary symptoms: results from a specialist centre.

Background: Index admission laparoscopic cholecystectomy (ALC) is the treatment of choice for patients admitted with biliary symptoms but is performed in less than 15% of these admissions. We analysed our results for ALC within a tertiary hepatobiliary centre.

Methods: Data from all cholecystectomies carried out under the care of the two senior authors from 1998 to 2008 were prospectively collected and interrogated.

Predictors of blood transfusion requirement in elective liver resection.

Background: Liver resection remains major surgery frequently requiring intra-operative blood transfusion. Patients are typically over cross-matched, and with blood donor numbers falling, cross-matching and transfusion policies need rationalizing.

Aim: To identify predictors of peri-operative blood transfusion.

The effect of anticoagulant pharmacotherapy on fracture healing.

Background: There is in vitro and in vivo evidence that anticoagulants impair normal bone metabolism, and it is widely believed that this may impair fracture healing. However, there are only a few heterogeneous in vivo animal studies confirming this and the mechanisms are not fully understood.

Objective: To review the literature concerning the effects of anticoagulants on fracture healing, and to present current understanding of the mechanisms involved by reviewing in vivo studies of bone biology and in vitro studies of bone cells.

Obesity in Tonga: A cross-sectional comparative study of perceptions of body size and beliefs about obesity in lay people and nurses.

Background: Obesity is a major public health issue in Tonga, where prevalence is significantly higher than in Europe and North America. Obesity and its health-related complications are likely to increase as a result of western influences on diet and lifestyle. The aim of this study was to investigate perceptions of body size in Tongan lay people and nurses, and their beliefs about the causes of obesity and its consequences for health.
