ABSTRACT
INTRODUCTION: Variation in access to parenteral nutrition (PN) in patients with intestinal failure secondary to malignant bowel obstruction (MBO) exists due to differing practice, beliefs and resource access. We aimed to examine differences in nutritional care pathways and outcomes, by referral to nutrition team for PN in patients with MBO. METHODS: This is a retrospective cohort study of MBO adults admitted to eight UK hospitals within a year and 1 year follow-up. Demographic, nutritional and medical data were analysed by comparing patients referred (R) or not referred (NR) for PN. Differences between groups were tested by Kruskal-Wallis, Chi-Squared tests and multi-level regression and survival using Cox regression. RESULTS: 232 patients with 347 MBO admissions [median 66yr, (IQR: 55-74yrs), 67 % female], 79/232 patients were referred for PN (R group). Underlying primary malignancies of gynaecological and gastrointestinal origin predominated (71 %) and 78 % with metastases. Those in the NR group were found to be older, weigh more on admission, and more likely to be treated conservatively compared to those in the R group. For 123 (35 %) admissions, patients were referred to a nutrition team, and for 204 (59 %) admissions, patients were reviewed by a dietician. Multi-disciplinary team discussion and dietetic contact were more likely to occur in the R group-123/347 admissions (R vs NR group: 27 % vs. 7 %, P = 0.001; 95 % vs 39 %, P < 0.0001). Median admission weight loss was 8 % (IQR: 0 to 14). 43/123 R group admissions received inpatient PN only, with 32 patients discharged or already established on home parenteral nutrition. Overall survival was 150 days (126-232) with no difference between R/NR groups. CONCLUSION: In this multi-centre study evaluating nutritional care management of patients with malignant bowel obstruction, only 1 in 3 admissions resulted in a referral to the nutrition team for PN, and just over half were reviewed by a dietician. Further prospective research is required to evaluate possible consequences of these differential care pathways on clinical outcomes and quality of life.

INTRODUCTION: Maintaining adequate nutritional status can be a challenge for patients with small bowel neuroendocrine tumours (NETs). Surgical resection could result in short bowel syndrome (SBS), whilst without surgical resection there is a considerable risk of ischemia or developing an inoperable malignant bowel obstruction (IMBO). SBS or IMBO are forms of intestinal failure (IF) which might require treatment with home parenteral nutrition (HPN). Limited data exist regarding the use of HPN in patients with small bowel neuroendocrine tumours, and it is not frequently considered as a possible treatment. METHODS: A systematic review was performed regarding patients with small bowel NETs and IF to report on overall survival and HPN-related complications and create awareness for this treatment. RESULTS: Five articles regarding patients with small bowel NETs or a subgroup of patients with NETs could be identified, mainly case series with major concerns regarding bias. The studies included 60 patients (range 1-41). The overall survival time varied between 0.5 and 154 months on HPN. However, 58% of patients were alive 1 year after commencing HPN. The reported catheter-related bloodstream infection rate was 0.64-2 per 1000 catheter days. CONCLUSION: This systematic review demonstrates the feasibility of the use of HPN in patients with NETs and IF in expert centres with a reasonable 1-year survival rate and low complication rate. Further research is necessary to compare patients with NETs and IF with and without HPN and the effect of HPN on their quality of life.

BACKGROUND AND AIMS: Only limited information is available on the use of home parenteral nutrition (HPN) in patients with advanced neuroendocrine tumours (NETs) causing intestinal failure (IF). This study aims to report the outcomes of the explore the use of HPN in this patient cohort, in the largest case series to date. METHODS: A retrospective study in the United Kingdom and the Netherlands was performed, using the UK National British Artificial Nutrition Survey (BANS) and local databases in the Netherlands. Data regarding age, sex, NET grading, staging, treatment, HPN characteristics and survival outcomes were collected. RESULTS: Data were collected on 41 patients (n = 18 males, 44%) with a median age of 65. Most primary tumours were in the small bowel (n = 35, 85%). The NETs were Grade 1 (n = 16, 39%), Grade 2 (n = 7, 17%), Grade 3 (n = 1, 2%). In 28 patients (n = 68%) there was stage IV disease with metastases located in the peritoneum, mesentery and or liver. There were two indications for HPN; short bowel syndrome (n = 27, 66%) and inoperable malignant bowel obstruction (n = 14, 34%). The median period on HPN was 11 months (interquartile range 4-25 months). 11 patients were still alive and receiving HPN treatment after 2 years, and 6 patients after 3 years. Six patients (22%) with short bowel syndrome (SBS) could be weaned from HPN. There was a statistically significant improved survival for patients with short bowel syndrome (median 24 months) compared to inoperable malignant bowel obstruction (median 7 months). The catheter-related bloodstream infection rate was comparable to other HPN patient cohorts at 1.0 per 1000 catheter days. CONCLUSION: This study shows that HPN can be used safely in patients with NET and IF to increase survival beyond that reasonably expected in the context of either short bowel syndrome or inoperable malignant bowel obstruction. Patients with short bowel syndrome are most likely to benefit. Further prospective studies are necessary to validate survival benefits and to demonstrate the effect of HPN on quality of life.

BACKGROUND: The United Kingdom nutrition database monitors the changing landscape of adult home parenteral nutrition support (HPS) to inform clinicians and policy makers of the need for this life-saving treatment. METHODS: The UK database is administered by the British Association for Parenteral and Enteral Nutrition. Data for home parenteral nutrition (HPN) has been collected since 2005 and home intravenous fluids (HIVFs) since 2011. During this study the reporting of data to the database by healthcare workers has been voluntary. Data were analyzed using linear regression. RESULTS: A threefold increase of new registrations for patients receiving HPS was noted on this 10-year period, with a notable increase in the number of patients with advanced malignancy supported with HPS. Crohn's disease and short bowel syndrome were the leading causes for both HPN and HIVF use in the UK. A statistically significant increase in older (P < 0.001) and less independent patients using HPS was noted. CONCLUSION: The prevalence of HPS is steadily increasing in size with the broadening of its acceptable performance status. The launch of the Intestinal Failure Registry and mandatory registration will increase accuracy in data reporting.

BACKGROUND: Despite multimodal therapy 5-15% of patients who undergo resection for advanced rectal cancer (LARC) will develop local recurrence. Management of locally recurrent rectal cancer (LRRC) presents a significant therapeutic challenge and even with modern exenterative surgery, 5-year survival rates are poor at 25-50%. High rates of local and systemic recurrence in this cohort are reflective of the likely biological aggressiveness of these tumour types. This review aims to appraise the current literature identifying pathological factors associated with survival and tumour recurrence in patients undergoing exenterative surgery. METHODS: A systematic review was carried out searching MEDLINE, EMBASE and COCHRANE Trials database for all studies assessing pathological factors influencing survival following pelvic exenteration for LARC or LRRC from 2010 to July 2021 following PRISMA guidelines. Risk of bias was assessed using QUIPS tool. RESULTS: Nine cohort studies met inclusion criteria, reporting outcomes for 2864 patients. Meta-analysis was not possible due to significant heterogeneity of reported outcomes. Resection margin status and nodal disease were the most commonly reported factors. A positive resection margin was demonstrated to be a negative prognostic marker in six studies. Involved lymph nodes and lymphovascular invasion also appear to be negative prognostic markers with tumour stage to be of lesser importance. No studies assessed other adverse tumour features that would not otherwise be included in a standard histopathology report. CONCLUSION: Pathological resection margin status is widely demonstrated to influence disease free and overall survival following pelvic exenteration for rectal cancer. With increasing R0 rates, other adverse tumour features must be explored to help elucidate differences in survival and potentially guide tailored oncological treatment.

BACKGROUND AND AIMS: Patients with intestinal failure often need long-term home parenteral support (PS). We aimed to determine how the underlying diagnosis, complications and survival had changed over the last 36 years in the UK's largest IF centre. METHODS: 978 adult home PS patient records were analysed from January 1979 until October 2016. The age, sex, underlying aetiology, complications and survival was compared over 5-year periods. RESULTS: Pre-1990 to 2011-2016, numbers increased from 29 to 451, the mean age of patients increased from 31 ± 16.5 to 52 ± 17.6 years. The percentage of patients with IF due to surgical complications increased (3.4%-28.8%, p < 0.001)), while those with inflammatory bowel disease decreased (37.9%-22.6%, p < 0.001). Complication of home PS reduced: catheter related blood stream infections (CRBSI) 71.4% to 42,2%, CVC thrombosis 34.5%-5.3%. Intestinal failure associated liver disease (IFLAD) 10.3%-1.8%. Patients with dysmotility, scleroderma and a congenital aetiology had the highest incidence of CRBSI and CVC Thrombosis. Overall survival was greater pre-1995 [HR 0.2-0.4 (p = 0.02)] most likely associated with an increase in mean age. Survival for patients without malignancy was 90%, 66%, 55%, 45%, 33% and 25% at 1,5, 10, 15, 20 and 30 years respectively. Multivariate analysis demonstrated a relationship between survival and age of starting home PS; type of home PS; presence or absence of the colon in continuity; and underlying aetiology. CONCLUSION: Demand for home PS is increasing in particular for advanced malignancy, post-surgical complications and older more co-morbid patients. Complications of home PS are reducing over the last 30 years and 10-year survival for non-malignant aetiologies improving. Survival and changes in aetiology in intestinal failure.

BACKGROUND: Colorectal cancer is associated with secondary sarcopenia (muscle loss) and myosteatosis (fatty infiltration of muscle) and patients who exhibit these host characteristics have poorer outcomes following surgery. Furthermore, patients, who undergo curative advanced rectal cancer surgery such as pelvic exenteration, are at risk of skeletal muscle loss due to immobility, malnutrition and a post-surgical catabolic state. Neuromuscular electrical stimulation (NMES) may be a feasible adjunctive treatment to help ameliorate these adverse side-effects. Hence, the purpose of this study is to investigate NMES as an adjunctive pre- and post-operative treatment for rectal cancer patients in the radical pelvic surgery setting and to provide early indicative evidence of efficacy in relation to key health outcomes. METHOD: In a phase II, double-blind, randomised controlled study, 58 patients will be recruited and randomised (1:1) to either a treatment (NMES plus standard care) or placebo (sham-NMES plus standard care) group. The intervention will begin 2 weeks pre-operatively and continue for 8 weeks after exenterative surgery. The primary outcome will be change in mean skeletal muscle attenuation, a surrogate marker of myosteatosis. Sarcopenia, quality of life, inflammatory status and cancer specific outcomes will also be assessed. DISCUSSION: This phase II randomised controlled trial will provide important preliminary evidence of the potential for this adjunctive treatment. It will provide guidance on subsequent development of phase 3 studies on the clinical benefit of NMES for rectal cancer patients in the radical pelvic surgery setting.

BACKGROUND/AIMS: Refeeding syndrome can result following excessive feeding of malnourished patients. The syndrome remains poorly defined but encompasses a range of adverse effects including electrolyte shifts, hyperglycaemia and other less well-defined phenomena. There are additional risks of underfeeding malnourished individuals. Studies of refeeding syndrome have generally focussed on critical care environments or patients with anorexia nervosa. Here we have conducted a two-centre, prospective, double-blind, randomised controlled trial amongst all patients referred to hospital nutrition support teams for intravenous nutrition support. We sought to determine whether electrolyte and other abnormalities suggestive of refeeding syndrome risk varied depending on initial rate of intravenous feeding. METHODS: Patients at moderate or high risk of refeeding syndrome, as defined by United Kingdom National Institute of Health and Care Excellence guidelines, were screened for inclusion. Patients were randomised to receive either high (30 kcal/kg/day, 0.25 gN/kg/day) or low (15 kcal/day, 0.125 gN/kg/day) rate feeding for the first 48 h prior to escalation to standard parenteral nutrition regimens. The primary outcome was rates of potential refeeding risks within the first 7 days as defined by electrolyte imbalance or hyperglycaemia requiring insulin. Secondary outcomes included effects on QTc interval, infections and length of hospital stay. Statistical analysis was performed with χ2 or Wilcoxon rank sum tests and all analysis was intention-to-treat. Problems with study recruitment led to premature termination of the trial. Registered on the EU Clinical Trials Register (EudraCT number 2007-005547-17). RESULTS: 534 patients were screened and 104 randomised to either high or low rate feeding based on risk of refeeding syndrome. Seven patients were withdrawn prior to collection of baseline demographics and were excluded from analysis. 48 patients were analysed for the primary outcome with potential refeeding risks identified in 46%. No differences in risks were seen between high and low rate feeding (p > 0.99) or high and moderate risk feeding (p = 0.68). There were no differences in QTc abnormalities, infection rates, or hospital length of stay between groups. CONCLUSIONS: In this randomised trial of rates of refeeding risk, in patients pre-stratified as being at high or moderate risk, we found no evidence of increased refeeding related disturbances in those commenced on high rate feeding compared to low rate. No differences were seen in secondary endpoints including cardiac rhythm analysis, infections or length of stay. Our study reflects real world experience of patients referred for nutrition support and highlights challenges encountered when conducting clinical nutrition research.

This case report highlights an unusual presentation of acute adrenal infarction in a Covid-19 patient who presented with abdominal symptoms and hyponatraemia. We discuss the recent literature reviewing how Covid-19 creates a hypercoaguable state, with acute adrenal infarction as a possible prothrombotic complication.
ABSTRACT
We present the case of a 16 year old girl who developed an aggressive colitis in the context of a prior biopsy proven autoimmune pancreatitis, which presented with obstructive jaundice at the age of 13 year. This history prompted prospective investigation and the discovery of compelling evidence to make a diagnosis of IgG4-related sclerosing disease with extra-pancreatic colonic involvement on the basis of raised serum IgG4 levels and a florid colonic IgG4 plasma cell infiltrate with over 20 IgG4 positive plasma cells/hpf. The colitis was resistant to conventional therapy but responded dramatically to treatment with the anti-TNFα monoclonal antibody, adalimumab. This is the first case to report both the effectiveness of adalimumab in treating IgG4 positive colitis in a patient with IgG4-related sclerosing disease, and to prospectively record resolution of an IgG4 positive colonic infiltrate with immunosuppression.

Extrahepatic arterioportal fistulas are a rare cause of portal hypertension in infants and adults. Most cases of arterioportal fistulas in adults are due to trauma, liver biopsy, surgery or tumours. The authors present a case of arterioportal fistula diagnosed in adult life without any of the above aetiologies. The patient became acutely symptomatic with diarrhoea and ascites at the age of 66 years and was successfully treated with a single endovascular embolisation procedure after failed medical therapy.
