Abstract
INTRODUCTION After excluding anaesthetic gases, around one-third of carbon emissions from surgical procedures are from consumables. This sustainable quality improvement project revised the laparoscopic appendicectomy surgical set at a large teaching hospital, with the aim of reducing unnecessary usage of disposable laparoscopic ports and surgical instruments. METHODS A prospective audit of 25 consecutive laparoscopic appendicectomies (5% of annual appendicectomies performed at the Trust) was conducted to assess use of disposable instruments. The financial and environmental costs of the five most commonly used disposable instruments were calculated and annual cost of current practice determined. A revised surgical set was created to include additional reusable instruments and new reusable ports. A reaudit of disposable surgical instrument usage was conducted and the financial and environmental impact of the new set compared with the results from the initial audit. RESULTS A total of 109 disposable instruments were opened in 25 appendicectomies, costing an estimated £49,656 and 692kg CO2 equivalent (CO2e) annually. Following rollout of the revised appendicectomy set, there was a significant reduction in disposable instrument usage (median four versus one instruments per case, p<0.00001). The revised set is predicted to reduce annual disposable instrument usage from 2,180 to 705 instruments (68% reduction), saving £219,452 and 3.02 tonnes CO2e over the estimated seven-year lifecycle of the reusable instruments. CONCLUSIONS Updating a laparoscopic appendicectomy set to include additional/new reusable instruments can lead to a marked reduction in disposable surgical instrument usage. This results in significant projected financial and CO2e savings.

Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
BACKGROUND Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting. METHODS Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.). RESULTS Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter 'no major postoperative complication' had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome. CONCLUSION Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract
BACKGROUND Data on the long-term symptom burden in patients surviving oesophageal cancer surgery are scarce. The aim of this study was to identify the most prevalent symptoms and their interactions with health-related quality of life. METHODS This was a cross-sectional cohort study of patients who underwent oesophageal cancer surgery in 20 European centres between 2010 and 2016. Patients had to be disease-free for at least 1 year. They were asked to complete a 28-symptom questionnaire at a single time point, at least 1 year after surgery. Principal component analysis was used to assess for clustering and association of symptoms. Risk factors associated with the development of severe symptoms were identified by multivariable logistic regression models. RESULTS Of 1081 invited patients, 876 (81.0 per cent) responded. Symptoms in the preceding 6 months associated with previous surgery were experienced by 586 patients (66.9 per cent). The most common severe symptoms included reduced energy or activity tolerance (30.7 per cent), feeling of early fullness after eating (30.0 per cent), tiredness (28.7 per cent), and heartburn/acid or bile regurgitation (19.6 per cent). Clustering analysis showed that symptoms clustered into six domains: lethargy, musculoskeletal pain, dumping, lower gastrointestinal symptoms, regurgitation/reflux, and swallowing/conduit problems; the latter two were the most closely associated. Surgical approach, neoadjuvant therapy, patient age, and sex were factors associated with severe symptoms. CONCLUSION A long-term symptom burden is common after oesophageal cancer surgery.

Abstract
BACKGROUND The Esophagectomy Complications Consensus Group (ECCG) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA) have set standards in reporting outcomes after oesophagectomy. Reporting outcomes from selected high-volume centres or centralized national cancer programmes may not, however, be reflective of the true global prevalence of complications. This study aimed to compare complication rates after oesophagectomy from these existing sources with those of an unselected international cohort from the Oesophago-Gastric Anastomosis Audit (OGAA). METHODS The OGAA was a prospective multicentre cohort study coordinated by the West Midlands Research Collaborative, and included patients undergoing oesophagectomy for oesophageal cancer between April and December 2018, with 90 days of follow-up. RESULTS The OGAA study included 2247 oesophagectomies across 137 hospitals in 41 countries. Comparisons with the ECCG and DUCA found differences in baseline demographics between the three cohorts, including age, ASA grade, and rates of chronic pulmonary disease. The OGAA had the lowest rates of neoadjuvant treatment (OGAA 75.1 per cent, ECCG 78.9 per cent, DUCA 93.5 per cent; P < 0.001). DUCA exhibited the highest rates of minimally invasive surgery (OGAA 57.2 per cent, ECCG 47.9 per cent, DUCA 85.8 per cent; P < 0.001). Overall complication rates were similar in the three cohorts (OGAA 63.6 per cent, ECCG 59.0 per cent, DUCA 62.2 per cent), with no statistically significant difference in Clavien-Dindo grades (P = 0.752). However, a significant difference in 30-day mortality was observed, with DUCA reporting the lowest rate (OGAA 3.2 per cent, ECCG 2.4 per cent, DUCA 1.7 per cent; P = 0.013). CONCLUSION Despite differences in rates of co-morbidities, oncological treatment strategies, and access to minimal-access surgery, overall complication rates were similar in the three cohorts.

Abstract
INTRODUCTION Elective surgery in the UK came to a halt during the early part of the COVID-19 pandemic. As COVID-19-related infection and mortality rates in Devon and Cornwall were relatively low, however, urgent elective surgery continued in Plymouth, with the necessary precautions in place. This study aimed to assess outcomes following Ivor Lewis oesophagectomy (ILO) during the pandemic. METHODS We prospectively analysed details of 20 consecutive patients who underwent ILO for cancer over a 3-month period between 17 March and 12 June 2020. All patients underwent COVID-19 swab testing 24-48 hours before surgery and during admission when clinically indicated. The primary outcome measure was COVID-19-related morbidity. Secondary outcome measures were non-COVID-19-related morbidity, mortality and length of hospital stay. RESULTS Twenty patients underwent ILO during the study period. All patients identified as white British. No patients tested positive for COVID-19 pre- or postoperatively. There was no COVID-19-related morbidity. There was no in-hospital mortality. Seven patients developed pneumonia, which settled with antibiotics. One patient developed an anastomotic leak, which was treated conservatively. One patient returned to theatre for a para-conduit hernia repair. The median length of hospital stay was nine days. One patient required admission to the high dependency unit for inotropic support for two days. CONCLUSIONS ILO can be performed safely during the COVID-19 pandemic with the necessary precautions in place.

Abstract
Nutrition and post-operative feeding in oesophageal cancer resections for enhanced recovery remain a controversial subject. Feeding jejunostomy tubes (FJT) have been used post-operatively to address the subject but evidence to support its routine use is contentious. There is currently no data on FJT use in England for oesophageal cancer resections. Knowledge regarding current FJT usage, and rationale for its use may provide a snapshot of the trend and current standing on FJT use by resectional units in England. A standardised survey was sent electronically to all oesophageal resectional units in the United Kingdom (UK) between October 2016 and January 2018. In summary, the questionnaire probes into current FJT use, rationale for its usage, consideration of cessation of its use, and rationale of cessation of its use for units not using FJT. The resectional units were identified using the National Oesophago-Gastric Cancer Audit (NOGCA) progress report 2016 and 1 selected resectional unit from Northern Ireland, Scotland, and Wales, respectively. Performance data of those units were collected from the 2017 NOGCA report. Out of 40 units that were eligible, 32 (80.0%) centres responded. The responses show a heterogeneity of FJT use across the resectional centres. Most centres (56.3%) still place FJT routinely with 2 of 18 (11.1%) were considering stopping its routine use. FJT was considered a mandatory adjunct to chemotherapy in 3 (9.4%) centres. FJT was not routinely used in 9 (28.1%) of centres with 5 of 9 (55.6%) reported previous complications and 4 of 9 (44.4%) cited using other forms of nutrition supplementation as factors for discontinuing FJT use. There were 5 (15.6%) centres with divided practice among its consultants. Of those 2 of 5 (40.0%) were considering stopping FJT use, and hence, a total of 4 of 23 (17.4%) of units are now considering stopping routine FJT use. In conclusion, the wider practice of FJT use in the UK remains heterogenous. More research regarding the optimal post-operative feeding regimen needs to be undertaken.

Abstract
INTRODUCTION In the present study the ante partum ruminating behavior and the later birth course were examined. Between May 2016 and April 2017 all cows, on a North German farm with 430 Holstein Friesian cows, were equipped with a transponder recording the ruminating behavior at least one week before the calculated date of birth. In total, 28 births could be monitored. Regardless of the course of birth, a decrease in ruminal activity was observed in all animals in the days before birth. The most significant decrease was on the last day before the birth. A significant difference occurred only at certain times. The present study confirmed an association between the early decline in ruminal activity and any imminent -dystocia. Further and in-depth studies are needed to create an appropriate algorithm.

Abstract
Two releases from steam assisted gravity drainage (SAGD) wellheads occurred 3 yr apart. To track recovery of the affected areas, red-backed voles were studied 1 and 4 yr later, using population estimates, hepatic detoxification effort, body condition, and tissue metal levels as bioindicators of site recovery. From years 1 to 4, higher ethoxyresorufin-O-deethylase induction was no longer evident, capture rate was lower, and body lead residues were no longer (inversely) correlated with body condition.

Abstract
Delayed gastric emptying (DGE) is a common morbidity that affects 10%-50% of Ivor-Lewis gastroesophagectomy (ILGO) patients. DGE management is variable with no gold standard prevention or treatment. We conducted a study to assess the effectiveness of intraoperative pyloric botulinum toxin injection in preventing DGE. All patients undergoing an ILGO for curative intent, semi-mechanical anastomosis, and enhanced recovery between 1st December 2011 and 30th June 2017 were included. Patients with pyloroplasties were excluded and botulinum toxin was routinely given from the 2nd April 2016. We compared botulinum toxin injection (BOTOX) against no intervention (NONE) for patient demographics, adjuvant therapy, surgical approach, DGE incidence, length of stay (LOS), and complications. Additionally, we compared pneumonia risk, anastomotic leak rate, and LOS in DGE versus non-DGE patients. DGE was defined using nasogastric tube input/output differences and chest X-ray appearance according to an algorithm adopted in our unit, which were retrospectively applied. There were 228 patients: 65 (28.5%) received botulinum toxin and 163 (71.5%) received no intervention. One hundred twenty-four (54.4%) operations were performed laparoscopically, of which 11 (4.8%) were converted to open procedures, and 104 (45.6%) were open operations. DGE incidence was 11 (16.9%) in BOTOX and 29 (17.8%) in NONE, P = 0.13. Medical management was required in 14 of 228 (6.1%) cases: 3 (4.6%) in BOTOX and 11 (4.8%) in NONE. Pyloric dilatation was required in 26 of 228 (11.4%): 8 of 65 (12.3%) in the BOTOX and 18 of 163 (11.0%) in NONE. There were no significant differences between groups and requirement for intervention, P = 0.881. Overall median LOS was 10 (6.0-75.0) days: 9 (7.0-75.0) in BOTOX and 10 (6.0-70.0) in NONE, P = 0.516. In non-DGE versus DGE patients, median LOS was 9 (6-57) versus 14 (7-75) days (P < 0.0001), pneumonia incidence of 27.7% versus 30.0% (P = 0.478), and anastomotic leak rate of 2.1% versus 10.0% (P = 0.014). Overall leak rate was 3.5%. Overall complication rate was 67.1%, including minor/mild complications. There were 43 of 65 (66.2%) in BOTOX and 110 of 163 (67.5%) in NONE, P = 0.482. In-hospital mortality was 1 (0.44%), 30-day mortality was 2 (0.88%), 90-day mortality was 5 (2.2%), and there were no 30-day readmissions. Intraoperative pyloric botulinum toxin injections were ineffective in preventing DGE (BOTOX vs. NONE: 16.9% vs. 17.8%) or reducing postoperative complications. DGE was relatively common (17.5%) with 11.4% of patients requiring postoperative balloon dilatation. DGE also resulted in prolonged LOS (increase from 9 to 14 days) and significant increase in leak rate from 2.1% to 10.0%. A better understanding of DGE will guide assessment, investigation, and management of the condition.

Abstract
To assess the ecological impacts of two independent accidental bitumen releases from two steam assisted gravity drainage (SAGD) wells in the Athabasca oil sands region, a multiple lines of evidence (LOE) approach was developed. Following the release in 2010, action was taken to minimize environmental impact, including the selective removal of the most highly impacted vegetation and the use of oil socks to minimize possible runoff. An ecological risk assessment (ERA) was then conducted based on reported concentrations of bitumen related contaminants in soil, vegetation, and water. Results of biological assessments conducted at the site were also included in the risk characterization. Overall, the conclusion of the ERA was that the likelihood of long-term adverse health effects to ecological receptors in the area was negligible. To provide evidence for this conclusion, a small mammal sampling plan targeting Southern red-back voles (Myodes gapperi) was carried out at two sites and two relevant reference areas. Voles were readily collected at all locations and no statistically significant differences in morphometric measurements (i.e., body mass, length, foot length, and adjusted liver weight) were found between animals collected from impact zones of varying levels of coverage. Additionally, no trends corresponding with bitumen coverage were observed with respect to metal body burden in voles for metals that were previously identified in the source bitumen. Hepatic ethoxyresorufin-O-deethylase (EROD) activity was statistically significantly elevated in voles collected from the high impact zones of sites compared to those collected from the reference areas, a finding that is indicative of continued exposure to contaminants. However, this increase in EROD was not correlated with any observable adverse population-wide biological outcomes. Therefore the biological sampling program supported the conclusion of the initial ERA and supported the hypothesis of no significant long-term population-wide ecological impact of the accidental bitumen releases.

Abstract
On April 17, 2012, two adult females presented to the hospital with symptoms of botulism. Patient A displayed shortness of breath, increasing lethargy, ptosis, and fixed and dilated pupils, and was intubated after admission. Patient B presented with shortness of breath, vomiting, and stridor. Both patients consumed a meal consisting of a traditionally prepared salted fish, fesikh, on the evening of April 16 during a gathering to celebrate Sham el-Nessim, an Egyptian holiday marking the beginning of spring. Foodborne botulism was suspected based on symptoms and consumption of potentially hazardous food. Antitoxin was administered to both patients on April 18. Another attendee of the Sham el-Nessim gathering (patient C), who also consumed the implicated food, developed symptoms consistent with botulism on April 18. Clinical specimens from all three symptomatic attendees tested positive for either Clostridium botulinum or type E botulinum neurotoxin. Fesikh remaining from the shared meal contained both type E botulinum neurotoxin and C. botulinum type E organisms. Unsold fesikh shad and fesikh sardines tested positive for C. botulinum type E, while unsold fesikh mullet pieces in oil tested positive for both C. botulinum type E and type E botulinum neurotoxin. After consultation with public health investigators, all fesikh products were voluntarily withheld from sale by the manufacturer prior to laboratory confirmation of contamination. Additional illnesses were likely prevented by these precautionary holds, which underscores the importance of timely public health action based on epidemiological evidence available in advance of laboratory results. This is the first documented outbreak of foodborne botulism associated with fesikh to occur in Canada.

Abstract
BACKGROUND Oesophageal resection is notoriously complicated and produces a cohort of patients prone to postoperative complications. Maintaining quality care demands a systematic approach to patient management yet postoperative recovery after oesophagectomy is often needlessly inefficient, heterogeneous and governed by the idiosyncrasies of the operating surgeon. Enhanced recovery after surgery (ERAS) programmes are now well established in colorectal surgery and here we describe the implementation and effectiveness of an ERAS programme for the postoperative management of Ivor Lewis oesophago-gastrectomy (ILOG). METHODS An ERAS programme was devised and implemented with the support of a dedicated in-hospital task-force. Three consultant surgeons allocated consecutive patients to the programme (ERAS) and outcomes were compared to consecutive patients not on the ERAS programme (non-ERAS) and a pre-ERAS cohort (pre-ERAS). Principal outcome measures were total length of stay (TLOS), Accordion postoperative complication grade and 30-day readmission rate. RESULTS 75 patients were enrolled on the ERAS programme, 41 continued as a non-ERAS cohort and 80 consecutive pre-ERAS patients were identified. A significant improvement in median TLOS was observed in the ERAS group (10 days r.7-58) compared to pre-ERAS (13 days r. 8-57) (p = <0.001) and non-ERAS patients (13 days r.8-42) (p = <0.001). No significant difference in Accordion scores for postoperative complications or 30-day readmission rates were observed. DISCUSSION The introduction of an ERAS programme after ILOG can significantly reduce TLOS without jeopardising patient safety or clinical outcomes. The successful introduction of an ERAS programme requires full motivation and support from all team members including the patient.

Abstract
BACKGROUND Isolated limb infusion with melphalan (ILI-M) corrected for ideal body weight (IBW) is a well-tolerated treatment for patients with in-transit extremity melanoma with an approximate 29 % complete response (CR) rate. Sorafenib, a multi-kinase inhibitor, has been shown to augment tumor response to chemotherapy in preclinical studies. METHODS A multi-institutional, dose-escalation, phase I study was performed to evaluate the safety and antitumor activity of sorafenib in combination with ILI-M. Patients with AJCC stage IIIB/IIIC/IV melanoma were treated with sorafenib starting at 400 mg daily for 7 days before and 7 days after ILI-M corrected for IBW. Toxicity, drug pharmacokinetics, and tumor protein expression changes were measured and correlated with clinical response at 3 months. RESULTS A total of 20 patients were enrolled at two institutions. The maximum tolerated dose (MTD) of sorafenib in combination with ILI-M was 400 mg. Four dose-limiting toxicities occurred, including soft tissue ulcerations and compartment syndrome. There were three CRs (15 %) and four partial responses (20 %). Of patients with the Braf mutation, 83 % (n = 6) progressed compared with only 33 % without (n = 12). Short-term sorafenib treatment did alter protein expression as measured with reverse phase protein array (RPPA) analysis, but did not inhibit protein expression in the MAP kinase pathway. Sorafenib did not alter melphalan pharmacokinetics. CONCLUSION This trial defined the MTD of systemically administered sorafenib in combination with ILI-M. Although some responses were seen, the addition of sorafenib to ILI-M did not appear to augment the effects of melphalan but did increase regional toxicity.

Abstract
Rainbow trout, Oncorhynchus mykiss, were infected with Ichthyophonus sp. and held at 10 degrees C, 15 degrees C and 20 degrees C for 28 days to monitor mortality and disease progression. Infected fish demonstrated more rapid onset of disease, higher parasite load, more severe host tissue reaction and reduced mean-day-to-death at higher temperature. In a second experiment, Ichthyophonus-infected fish were reared at 15 degrees C for 16 weeks then subjected to forced swimming at 10 degrees C, 15 degrees C and 20 degrees C. Stamina improved significantly with increased temperature in uninfected fish; however, this was not observed for infected fish. The difference in performance between infected and uninfected fish became significant at 15 degrees C (P = 0.02) and highly significant at 20 degrees C (P = 0.005). These results have implications for changes in the ecology of fish diseases in the face of global warming and demonstrate the effects of higher temperature on the progression and severity of ichthyophoniasis as well as on swimming stamina, a critical fitness trait of salmonids. This study helps explain field observations showing the recent emergence of clinical ichthyophoniasis in Yukon River Chinook salmon later in their spawning migration when water temperatures were high, as well as the apparent failure of a substantial percentage of infected fish to successfully reach their natal spawning areas.

Abstract
9025^ Background: ILI with melphalan dosing corrected for ideal body weight (IBW) is a well tolerated treatment for patients with in-transit extremity melanoma with an approximate 30% CR and 44% overall response rate. ADH-1 is a cyclic pentapeptide that disrupts N-cadherin adhesion complexes. ADH-1 when given systemically in a preclinical model with regional melphalan demonstrated synergistic antitumor activity and had minimal toxicity in a Phase I trial with M-ILI. Methods:AJCC stage IIIB or IIIC extremity melanoma patients were treated with 4000mg of ADH-1 administered systemically on Day 1 and 8 in addition to standard dose M-ILI corrected for IBW on Day 1. Drug pK, and N-cadherin IHC staining were performed on pretreatment tumor from all patients. The primary endpoint was response at 12 weeks determined by modified RECIST. Results: 46 patients were enrolled over 15 months at 4 institutions. Thirty-four patients are presently evaluable for 12 week response. In field responses include 14 CRs (41.2%%), 9 PRs (26.5%), 5 SDs (14.7%), and 6 PDs (17.6%). The OR rate was 67.7% and at a median follow-up of 30 weeks, 8 patients have sustained CRs over 6 months. Of 34 patients, 9 have developed disease outside the region of infusion (median time to progression 12 weeks) at median follow-up 36 weeks. N-cadherin was detected in 20 of 25 (80%) pretreatment tumor samples. Grade IV toxicities included CPK elevation (4), neutropenia (1), acute respiratory distress syndrome (1), pneumonitis (1), and pulmonary infiltrate (1). There were no limb losses or compartment syndromes. Conclusions:This study is not only the first prospective multi-center ILI trial but also the first ILI study to incorporate a targeted agent in an attempt to augment anti-tumor responses. The treatment was well tolerated with CR and OR rates that appear to be significantly improved from standard M-ILI alone. Targeting N-cadherin may represent a novel strategy for improving melanoma sensitivity to chemotherapeutic agents and warrants further investigation in a large randomized multi-center trial.

Abstract
9065 Background: Sorafenib is a multi-kinase inhibitor that may also enhance the cytotoxicity of concurrently administered chemotherapy. In a preclinical model of regionally advanced melanoma, the combination of systemic Sorafenib and regional melphalan led to augmented tumor responses. Methods: A Phase I multicenter study was performed to evaluate the safety and pharmacokinetics (PK) of systemic Sorafenib in combination with ILI-M in patients with measurable in-transit melanoma of the extremity. Sorafenib dose escalation cohorts consisted of 200mg, 300mg, and 400mg administered systemically twice daily for one week prior and one week after a standard dose ILI-M corrected for ideal body weight. Tumor biopsies pre-therapy and pre-ILI were obtained to assess molecular changes associated with Sorafenib pretreatment. Response was defined at 3 months using RECIST. Results: Nine pts with high disease burden, including 7 previous ILI-M alone failures, have been treated; 3 in the first cohort and 6 in the second cohort. There were no grade 5 toxicities. Four patients had CTCAE Grade 4 toxicities including neutropenia (2), CPK elevation (1), and skin ulceration (1). In the remaining 5 patients, there were no >grade 3 toxicities. The maximally tolerated dose (MTD) has not yet been defined. Initial in field response determination in 6 of the 9 patients out at least 3 months includes 2 partial responses and 4 disease progressions. Conclusions: Systemic Sorafenib administered pre and post ILI-M is a well tolerated, novel targeted therapy approach to regionally advanced melanoma. An additional 10 patients will be enrolled to define the MTD. Correlation of response with drug PK, Sorafenib downregulation of pErk and Mcl1, and a melphalan resistance signature is in progress. No significant financial relationships to disclose.

Abstract
BACKGROUND This study aims to determine what effect correcting melphalan dosing for ideal body weight (IBW) has on toxicity and response in isolated limb infusion (ILI) in patients with advanced extremity melanoma. METHODS This was an open observational study examining whether correcting the melphalan dose for IBW will influence response and toxicity in patients undergoing ILI for advanced extremity melanoma in 41 patients undergoing 42 procedures (13 without correction for IBW; and 29 with correction for IBW). Melphalan pharmacokinetics, limb toxicity, serologic toxicity, and response at 3 months were compared. RESULTS The corrected group had a lower estimated limb volume (V (esti)) to melphalan volume at steady state (V (ss)) (P < .0001) ratio as well as lower incidence of grade > or =3 regional toxicity, serologic toxicity, and compartment syndrome (P = .0249, P = .027, P = .02). There was a positive correlation of V (esti)/V (ss) to toxicity (P = .0127, r = .382). No significant difference in response (P = .3609) between the groups was found, although there was a trend of association between V (esti)/V (ss) and response (P = .051, r = .3383). CONCLUSIONS Correcting for IBW in ILI lowers toxicity without significantly altering response rates.

Abstract
INTRODUCTION We have previously shown that Picolax bowel preparation causes a significant dehydrating effect, which can be minimised by administering a calculated volume of intravenous fluid. The aim of this prospective study was to assess whether peri-operative outcome is affected by administering a calculated volume of intravenous fluid during bowel preparation. PATIENTS AND METHODS Patients having bowel preparation (Picolax: Ferring Pharmaceuticals Ltd, Middlesex, UK) prior to colonic surgery were prospectively randomised to receive no intravenous fluid (group 1) or calculated intravenous crystalloid based on their body weight (group 2), during preparation. In both groups, transfusion was protocol-driven. Outcome variables measured included intra-operative and postoperative intravenous fluid requirement, hourly recorded urine output for 24 h, number of patients transfused, number of units of blood transfused, time to the passage of flatus, time to having their bowels open, time until tolerating a full diet, complications and length of stay in hospital. RESULTS Thirty-three patients were recruited - group 1 (n = 18) and group 2 (n = 15). There were 24 men and 9 women, median age 69 years (range, 29-86 years). There was no significant difference between the groups with respect to age, sex, weight, ASA grade, pre-operative haemoglobin concentration, duration or type of operation. The total number of patients receiving a transfusion (P = 0.026) and the number of units of blood transfused (P = 0.017) was significantly greater in group 1. The number of units of blood transfused intra-operatively was significantly greater in group 1 (P = 0.029). Significantly fewer patients had a urine output < 30 ml/h in the first 24-h after operation (P = 0.046) in group 2. There was no difference between groups in other outcomes measures. CONCLUSIONS This study indicates that a calculated volume of intravenous fluid administered during bowel preparation improves patient outcomes with respect to blood transfusion and postoperative oliguria. We advocate calculated intravenous fluid administration in all patients undergoing bowel preparation prior to colonic surgery.

Abstract
INTRODUCTION Allogeneic blood transfusion confers a risk to the recipient. Recent trials in colorectal surgery have shown that the most significant factors predicting blood transfusion are pre-operative haemoglobin, operative blood loss and presence of a transfusion protocol. We report a randomised, controlled trial of oral ferrous sulphate 200 mg TDS for 2 weeks' pre-operatively versus no iron therapy. PATIENTS AND METHODS Patients diagnosed with colorectal cancer were recruited from out-patient clinic and haematological parameters assessed. Randomisation was co-ordinated via a telephone randomisation centre. RESULTS Of the 49 patients recruited, 45 underwent colorectal resection. There were no differences between those patients not receiving iron (n = 23) and the iron-supplemented group (n = 22) for haemoglobin at recruitment, operative blood loss, operation duration or length of hospital stay. At admission to hospital, the iron-supplemented group had a higher haemoglobin than the non-iron treated group (mean haemoglobin concentration 13.1 g/dl [range, 9.6-17 g/dl] versus 11.8 g/dl [range, 7.8-14.7 g/dl]; P = 0.040; 95% CI 0.26-0.97) and were less likely to require operative blood transfusion (mean 0 U [range, 0-4 U] versus 2 U [range, 0-11 U] transfused; P = 0.031; 95% CI 0.13-2.59). This represented a cost reduction of 66% (47 U of blood = pound4700 versus oral FeSO(4) at pound30 + 15 U blood at pound1500). At admission, ferritin in the iron-treated group had risen significantly from 40 microg/l (range, 15-222 microg/l) to 73 microg/l (range, 27-386 microg/l; P = 0.0036; 95% CI 46.53-10.57). CONCLUSIONS Oral ferrous sulphate given pre-operatively in patients undergoing colorectal surgery offers a simple, inexpensive method of reducing blood transfusions.

Abstract
BACKGROUND Nowadays, laparoscopic adrenalectomy is the "gold standard" procedure for the treatment of benign lesions. However, the situation is not so clearcut when the issue is laparoscopic excision of malignant adrenal tumors. We present our results of laparoscopic adrenalectomy for treating malignant tumors over the past decade. METHODS Between October 1995 and June 2004, 131 consecutive laparoscopic adrenalectomies were performed on 120 patients (11 synchronous bilateral procedures). All patients underwent a standardized investigation protocol during their workup for surgery. RESULTS There were only two conversions to laparotomy (1.6%). Complications that occurred during the procedure were limited to six patients (5%). Postoperative 30-days mortality was nil. Postoperative complications occurred in five patients (4.7%) during the first 30 days of recovery. The median hospital stay for all patients was 2.5 days (range = 2-10 days). Twelve patients (9%) had a malignant tumor: nine corticoadrenalomas, one pleomorphic sarcoma, one metastatic deposit from a previously excised colonic cancer, and one malignant pheochromocytoma. At mean followup of 34 months, mean survival time was 42.3 months for corticoadrenalomas that had undergone laparoscopy versus 29.7 months for those who had had a laparotomy. Five of the nine patients are alive and well at a mean of 37 months following surgery. One patient developed pulmonary metastases one year postsurgery; they were responsive to mitotane. Five years later, the same patient had a reoperation for an intra-abdominal retrogastric recurrence of her tumor and continues to do well. Another patient developed pulmonary metastases 22 months following adrenalectomy. Two patients died of metastatic intra-abdominal disease 20 and 7 months postsurgery. CONCLUSION When laparoscopic surgery is to used for cancer treatment, caution is the rule to maintain the primary objective of securing a survival rate at least as high as that for open surgery, without increased risk of recurrence. Considering the results presented within this study, it seems that the laparoscopic removal of a corticoadrenaloma should not worsen the prognosis, provided the surgeon respects the primary rules of oncologic resectional surgery. Any surgical conditions that would preclude the strict application of these criteria are contraindications to a laparoscopic procedure.

Abstract
Campylobacter jejuni remains the leading cause of bacterial gastroenteritis in developed countries, and yet little is known concerning the mechanisms by which this fastidious organism survives within its environment. We have demonstrated that C. jejuni 11168 can form biofilms on a variety of surfaces. Proteomic analyses of planktonic and biofilm-grown cells demonstrated differences in protein expression profiles between the two growth modes. Proteins involved in the motility complex, including the flagellins (FlaA, FlaB), the filament cap (FliD), the basal body (FlgG, FlgG2), and the chemotactic protein (CheA), all exhibited higher levels of expression in biofilms than found in stationary-phase planktonic cells. Additional proteins with enhanced expression included those involved in the general (GroEL, GroES) and oxidative (Tpx, Ahp) stress responses, two known adhesins (Peb1, FlaC), and proteins involved in biosynthesis, energy generation, and catabolic functions. An aflagellate flhA mutant not only lost the ability to attach to a solid matrix and form a biofilm but could no longer form a pellicle at the air-liquid interface of a liquid culture. Insertional inactivation of genes that affect the flagellar filament (fliA, flaA, flaB, flaG) or the expression of the cell adhesin (flaC) also resulted in a delay in pellicle formation. These findings demonstrate that the flagellar motility complex plays a crucial role in the initial attachment of C. jejuni 11168 to solid surfaces during biofilm formation as well as in the cell-to-cell interactions required for pellicle formation. Continued expression of the motility complex in mature biofilms is unusual and suggests a role for the flagellar apparatus in the biofilm phenotype.

Abstract
Biofilm formation may be important in the colonization of the food-processing environment by the food-borne pathogen Listeria monocytogenes. Listeria monocytogenes 568 formed adherent multicellular layers on a variety of test surfaces following growth at 37 degrees C with multiple transfers of the test surface into fresh medium. Microscopic examination of these adherent layers suggest that the cells were surrounded by extracellular material. The presence of a carbohydrate containing extracellular polymeric matrix was confirmed by labelling hydrated adherent layers with fluorescein-conjugated concanavalin A, indicating that these adherent layers are biofilms. To gain insight into the physiological state of cells in these biofilms, the proteomes from biofilm- and planktonic-grown cells from the same cultures were compared using 2-dimensional polyacrylamide gel electrophoresis. Nineteen proteins, which exhibited higher levels of expression in biofilm-grown cells, were successfully identified from the 2-D gels using a combination of MALDI-TOF and MS/MS. Proteins that were found to be more highly expressed in biofilm-grown cells were involved in stress response, envelope and protein synthesis, biosynthesis, energy generation, and regulatory functions. In biofilm-grown cells, many proteins in the pH range 4-6 ran as multiple spots arranged horizontally across the 2-D gels.

Abstract
BACKGROUND The efficacy of acute normovolaemic haemodilution (ANH) remains uncertain because of a lack of well-designed prospective randomized controlled trials. The aim of this study was to assess the effects of ANH on allogeneic transfusion, postoperative complications, and duration of stay. METHODS Consecutive patients undergoing major gastrointestinal surgery were randomized to a planned 3-unit ANH, or no ANH. Both groups underwent identical management including adherence to a transfusion protocol after surgery. Outcome measures included the number of patients receiving allogeneic blood, complications, and duration of stay. RESULTS 380 patients were screened of which 160 were included in the study, median age was 62 yr (range 23-90), 'ANH' n=78, 'no ANH' n=82. There was no significant difference between groups in the number of patients receiving allogeneic blood 22/78 (28%) vs 25/82 (30%), the total number of allogeneic units transfused (90 vs 93), complication rate, or duration of stay. Haemodilution significantly increased anaesthetic time, median 55 (range 15-90) vs 40 min (range 17-80) (P<0.001). Significantly fewer patients in the ANH group experienced oliguria in the immediate postoperative period 37/78 (47%) vs 55/82 (67%) (P=0.012). The most significant factors affecting transfusion were blood loss, starting haemoglobin, and age. When compared with ASA-matched historical controls, the introduction of a transfusion protocol reduced the transfusion rate in colorectal patients from 136/333 (41%) to 37/138 (27%), P=0.004. CONCLUSIONS In this large pragmatic study, ANH did not affect allogeneic transfusion rate in major gastrointestinal surgery. Preoperative haemoglobin, blood loss, and transfusion protocol are the key factors influencing allogeneic transfusion.

Abstract
Studies were done to determine the effect of mastic resin and its essential oil, alone and in conjunction with ethanol, on the growth of proteolytic strains of Clostridium botulinum in media, and on neurotoxin production in challenge studies with English-style crumpets. Preliminary studies, using a spot-on-the-lawn method, indicated that high levels of mastic resin in ethanol ( approximately 8% w/w) were required for complete inhibition of all strains of C. botulinum tested, but mastic resin in ethanol had a greater anti-botulinal effect than ethanol alone. However, only low levels of mastic oil ( approximately 0.3% v/v) were required for inhibition of proteolytic strains of C. botulinum. Both studies showed a strain specific inhibition, with C. botulinum type A strains being more sensitive to mastic resin and its essential oil than type B strains. However, mastic resin in ethanol proved to be more effective when used as a vapor phase inhibitor applied to cotton pads and placed inside inoculated plates than when added directly to media. While both mastic resin and its essential oil inhibited the growth of proteolytic strains of C. botulinum in vitro, they failed to inhibit neurotoxin production in challenge studies with C. botulinum in English-style crumpets.

Abstract
Air pollution particles are thought to kill > 500,000 people worldwide each year. The population most at risk appears to be elderly people with respiratory and cardiovascular disease. As yet, no commonly accepted mechanism has been proposed which can explain the cause of these deaths. Heart rate variability (HRV) was assessed in healthy elderly adults between the ages of 60 and 80 who were exposed twice for 2 h: once to clean air and once to concentrated ambient air pollution particles (CAPS). Changes in HRV were measured immediately before, immediately following, and 24 h after exposure. Elderly subjects experienced significant decreases in HRV in both time and frequency domains immediately following exposure. Some of these changes persisted for at least 24 h. These data were compared with HRV data collected from young healthy volunteers exposed to CAPS in a previous study, in which no CAPS-induced changes in HRV were found. These concentrated ambient air pollution particle-induced changes in heart rate variability in a controlled human exposure study extend similar findings reported in recent panel studies and suggest potential mechanisms by which particulate matter may induce adverse cardiovascular events.

Abstract
Model broth studies were carried out to investigate the effect of ethanol on the growth of proteolytic (group I) strains of Clostridium botulinum. Ethanol extended the pathogen's lag phase, decreased its exponential growth rate, and decreased its final level of growth in the stationary phase. In all cases, botulinum neurotoxin production was associated with growth. Micrographs of C. botulinum cultures grown at 37 degrees C in trypticase peptone glucose yeast extract (TPGY) broths containing 2 and 4% ethanol showed elongation of vegetative cells and interference with cell division. The inhibition of growth and toxin production at the ethanol level predicted (5.5%, wt/wt) was confirmed by microscopy and by the mouse bioassay. A subsequent study was carried out to determine the combined effect of ethanol (0 to 8% [wt/wt]), water activity (aw; 0.953 to 0.997), and pH (6.2 to 8.2) on the probability of the growth of and neurotoxin production by proteolytic strains of C. botulinum (10(3) spores per ml). Growth and neurotoxin production occurred in 1 to 3 days in TPGY broths without ethanol (0%) and in 2 to 4 days in broths containing 2% ethanol regardless of the aw or pH levels (P < 0.005). Growth and neurotoxin production were delayed by an ethanol concentration of 4% ethanol and completely inhibited by a concentration of 6%. At an ethanol concentration of 4%, the probability of growth and toxin production over 365 days (Pt) was influenced by aw and pH. After 365 days, the maximum probability of growth and toxin production (Pmax) was 1 for all but one combination. However, tau, the time it took for 50% of all eventually positive replicates for any given combination of barriers to show growth and/or turbidity, ranged from <3 to 229 days. All tubes of TPGY broths that showed no growth after 365 days were subcultured in fresh TPGY broths. In all cases, growth and toxin production occurred within 24 h at 37 degrees C, indicating the reversible (sporostatic and/or bacteriostatic) effect of ethanol on C. botulinum.

Abstract
AIMS Blood transfusions are often given to surgical patients. This study was designed to assess whether acute normovolaemic haemodilution (ANH) reduces exposure to allogeneic blood, affects clinical outcome and hospital stay, and is feasible in colorectal surgery. METHODS All ASA 1 and 11 patients undergoing colectomies performed between 1997 and 1999 were identified retrospectively from our colorectal cancer database to ascertain our current peri and postoperative transfusion practice. Twenty-six selected patients subsequently underwent ANH during colectomy surgery. The number of patients and units transfused were identified. RESULTS One hundred and twenty-three of 317 (39%) patients identified from our colorectal cancer database were transfused a total of 328 units (median 2, range 1-7). Of the 26 patients undergoing ANH, 4 (15%) were transfused a total of 13 units (median 3, range 2-5). The reduction in number of patients transfused was statistically significant (P=0.017). ANH increased anaesthetic time by a median of 19 min. There were no complications associated with ANH and the median hospital stay was 9 days (range 6-13). CONCLUSIONS In this pilot study of selected patients, ANH is a feasible and effective method of reducing allogeneic blood exposure in major colorectal surgery. A prospective randomised controlled trial is now urgently required.

Abstract
BACKGROUND Bowel preparation using purgatives has previously been shown significantly to increase haemoglobin concentration and decrease weight. This prospective randomized study assessed the effects of administering intravenous fluid during bowel preparation. METHODS Patients having bowel preparation with Picolax for colonic procedures were randomized prospectively to receive no intravenous fluid (group 1) or calculated intravenous crystalloid based on body-weight (group 2) during preparation. Physiological, haematological and biochemical variables were measured before and after bowel preparation. RESULTS Forty-one patients were recruited with a median age of 69 (range 29-86) years, 22 in group 1 and 19 in group 2. There was no difference between groups in any of the variables measured before bowel preparation. On completion, there was a significant difference between groups in mean weight loss (P = 0.01), postural change in systolic pressure (P = 0.015) and serum creatinine concentration (P = 0.008). In addition there was a significant fall in erect blood pressure after bowel preparation in group 1 (P = 0.02). The mean urine output in group 1 was 982 ml and in group 2 was 1808 ml (P = 0.004). The faeces weight between groups was not significantly different. CONCLUSION Picolax bowel preparation has a significant dehydrating effect, which can be minimized by administering a simultaneous volume of intravenous fluid (mean 2 litres in this study).

Abstract
AIMS To determine whether isolates of Listeria monocytogenes differ in their ability to adsorb and form biofilms on a food-grade stainless steel surface. METHODS AND RESULTS Strains were assessed for their ability to adsorb to a test surface over a short time period. Although some differences in numbers of bound cells were found among the strains, there were no correlations between the degree of adsorption and either the serotype or source of the strain. The ability of each strain to form a biofilm when grown with the test surface was also assessed. With the exception of a single strain, all strains adhered as single cells and did not form biofilms. Significant differences in adherence levels were found among strains. Strains demonstrating enhanced attachment produced extracellular fibrils, whereas those which adhered poorly did not. A single strain formed a biofilm consisting of adhered single cells and aggregates of cells. CONCLUSIONS Significant differences were found in the ability of various L. monocytogenes strains to attach to a test surface. In monoculture, the majority of strains did not form biofilms. SIGNIFICANCE AND IMPACT OF THE STUDY Differences in attachment and biofilm formation among strains provide a basis to study these characteristics in L. monocytogenes.
