RESUMO
BACKGROUND & AIMS: Short bowel syndrome leading to intestinal failure (SBS-IF) is a condition characterised by the inability of the gut to absorb the amount of water, nutrients and micronutrients needed to survive and requires long term home parenteral nutrition (HPN) to sustain life. Health care professionals (HCPs) working with patients with SBS-IF are aware of the daily challenges patients face. However, few have experienced the condition first-hand and put themselves 'in the shoes' of their patients. In Their Shoes (ITS) is an immersive simulation delivered through a smartphone application (app), in which participants experience the typical real-life challenges that somebody with SBS-IF will experience over a 24-h period, including social and psychological challenges. This study evaluated the impact of ITS simulation on HCPs working with adults with SBS-IF. METHODS: A representative sample of 27 multi-disciplinary team (MDT) members working on an Intestinal Failure Unit completed the ITS simulation over a 24-h period. A mixed methods design was used, which included participants completing a survey pre- and post-ITS experience, followed by focus groups and in-depth qualitative interviews. Pre- and post-intervention questions were analysed quantitively via paired t-tests and qualitative data arising from the focus groups and interviews were analysed using inductive thematic analysis. RESULTS: 25 participants (93%) completed 80% of the ITS challenges whilst 27 (100%) completed more than 50% challenges. Participants reported a 16% increase in knowledge, 18% increase in being able to talk to others about SBS and a 2% increase in empathy between pre- and post-simulation. Nineteen team members participated in focus groups and 10 in-depth interviews; qualitative analysis of digital recordings comprised four overarching themes: empathy; admiration and respect; empathy fatigue; learning experience. Despite the small and insignificant increase in empathy scores quantitatively, analysis of open-ended questions and qualitative data found that 74% of participants reported an increase in empathy levels whereas 26% felt it stayed the same. CONCLUSIONS: As a simulation-based learning method, ITS can have a positive impact on HCPs working into the SBS-IF setting. Positive benefits in clinical practice include increased levels of empathy, admiration and respect for patients amongst HCPs. Immersing into the ITS experience also allows HCPs to recognise the function and benefits to MDT working, both in terms of ensuring holistic patient centred care and managing HCP empathy fatigue.

Short bowel syndrome (SBS) and enterocutaneous or enteroatmospheric fistulas are common indications for home parenteral nutrition (HPN). However, there are few data describing factors influencing surgical decision-making or outcomes particularly following fistula development. We aimed to compare outcomes between patients with SBS and fistulas and explore surgical decision-making. HPN-dependent adults from 2001−2018 at a national reference centre were included in this study. HPN cessation was analysed using death as competing risk. In total, 465 patients (SBS (62%), fistula (38%)) were included, with median HPN dependency of 2.6 years. In total, 203 patients underwent reconstructive surgery; while frailty was the commonest reason for not undergoing surgery (49.2%), 22.7% declined surgery. Overall, 170 ceased HPN, with a probability of 13.8%, 34.1% and 38.3% at 1, 5 and 10 years, respectively. Patients undergoing surgery had higher nutritional autonomy rates (109.8 incidences/1000 patient years) compared to those not undergoing surgery (18.1 incidences/1000 patient years; p < 0.001). A total of 295 patients (63.4%) were predicted to cease HPN based on gastrointestinal anatomy but only 162/295 (54.9%) achieved this; those unable to do so were older with a higher comorbidity index. There were no differences in long-term nutritional and survival outcomes or surgical decisions between patients with SBS and fistulas, or between enterocutaneous and enteroatmospheric fistulas. This study represents one of the largest datasets describing the ability of HPN-dependent patients with SBS or fistulas to achieve nutritional autonomy. While reconstructive surgery facilitates HPN cessation, approximately one-fifth of patients declined surgery despite HPN dependency. These data will better inform patient expectation and help plan alternative therapies.

Intestinal failure (IF) is the inability of the gut to absorb necessary water, macronutrients, micronutrients, and electrolytes sufficient to sustain life and requiring intravenous supplementation or replacement. IF Types 1 and 2 are the initial phase of this condition and usually last for weeks to a few months. Type 3 IF (also known as chronic IF [CIF]) is a chronic and stable condition, usually irreversible, whose main treatment is home parenteral nutrition. CIF is a relatively rare condition, and its prevalence and different causes vary throughout the world. Due to its complexity, CIF requires a multidisciplinary team with experience in this field to achieve successful outcomes. This editorial aims to provide an overview of CIF in adults, emphasizing the challenges faced by clinicians when managing this rare entity, as well as outlining the role of the gastroenterologist.

PURPOSE: As the practice of nutritional support in patients with head and neck cancer (HNC) during curative radio(chemo)therapy is quite heterogeneous, we carried out a survey among European specialists. METHODS: A 19-item questionnaire was drawn up and disseminated via the web by European scientific societies involved in HNC and nutrition. RESULTS: Among 220 responses, the first choice was always for the enteral route; naso-enteral tube feeding was preferred to gastrostomy in the short term, while the opposite for period longer than 1 month. Indications were not solely related to the patient's nutritional status, but also to the potential burden of the therapy. CONCLUSION: European HNC specialists contextualize the use of the nutritional support in a comprehensive plan of therapy. There is still uncertainty relating to the role of naso-enteral feeding versus gastrostomy feeding in patients requiring < 1 month nutritional support, an issue that should be further investigated.

BACKGROUND: This practical guideline is based on the ESPEN Guidelines on Chronic Intestinal Failure in Adults. METHODOLOGY: ESPEN guidelines have been shortened and transformed into flow charts for easier use in clinical practice. The practical guideline is dedicated to all professionals including physicians, dieticians, nutritionists, and nurses working with patients with chronic intestinal failure. RESULTS: This practical guideline consists of 112 recommendations with short commentaries for the management and treatment of benign chronic intestinal failure, including home parenteral nutrition and its complications, intestinal rehabilitation, and intestinal transplantation. CONCLUSION: This practical guideline gives guidance to health care providers involved in the management of patients with chronic intestinal failure.

PURPOSE OF REVIEW: To provide an update on the recent evidence underpinning the approach to nutritional care in patients with severe primary chronic small bowel dysmotility. RECENT FINDINGS: Patients with severe chronic small intestinal dysmotility suffer nutritional and nonnutritional morbidity, both as a result of their underlying polysymptomatic, poorly understood condition and the interventions required. A proportion require artificial nutrition support; however, this is associated with impaired quality of life and associated complications. The approach to nutritional support must therefore engage a multidisciplinary team (MDT) to ensure that decisions to escalate beyond oral nutrition reflect individualised risk-benefit discussions while adopting a holistic approach to symptom management. Since nutritional outcomes are worse in those with the chronic intestinal pseudo-obstruction (CIPO) phenotype, differentiation into CIPO and non-CIPO subgroups, using a pragmatic diagnostic approach rather than invasive/poorly tolerated investigations, can be an important step in achieving nutritional care tailored to the individual. SUMMARY: Malnutrition in patients with severe chronic small intestinal dysmotility is multifactorial. Early engagement of a broad team that includes dietitians, psychologists and pain management experts is crucial to achieving the most beneficial and least harmful patient-centred nutritional care outcomes.

BACKGROUND: Catheter-related bloodstream infection (CRBSI) is a life-threatening complication of parenteral nutrition. Therefore, optimal management, ideally with catheter salvage, is required to maintain long-term venous access. OBJECTIVES: We aimed to evaluate successful catheter salvage rates in patients on home parenteral nutrition (HPN). METHODS: Studies were retrieved from medical databases, conference proceedings, and article reference lists. Data were collected relating to clinical outcomes of 3 treatments: systemic antibiotics, antimicrobial lock therapy (ALT), and catheter exchange. ORs and 95% CIs were calculated from a mixed logistic effects model. RESULTS: From 10,036 identified publications, 28 met the inclusion criteria (22 cohort studies, 5 case-control studies, and 1 randomized clinical trial), resulting in a total of 4911 CRBSIs. To achieve successful catheter salvage, the addition of an antimicrobial lock solution was superior to systemic antibiotics alone (OR: 1.75; 95% CI: 1.21, 2.53; P = 0.003). Recurrence of infection was less common in studies that used ALT than in those that used systemic antibiotics alone (OR: 0.26; 95% CI: 0.11, 0.61; P = 0.002). The catheter exchange group was excluded from multilevel regression analysis because only 1 included study applied this treatment. Successful salvage rates were highest for coagulase-negative staphylococci, followed by Gram-negative rods and Staphylococcus aureus . CONCLUSIONS: The addition of an antimicrobial lock solution seems beneficial for successful catheter salvage in HPN-dependent patients with a CRBSI. Future prospective randomized studies should identify the most effective and pathogen-specific strategy.This review was registered at www.crd.york.ac.uk/PROSPERO as CRD42018102959.

BACKGROUND: Patients with intestinal failure (IF) are prone to hypophosphatemia and shifts in magnesium and potassium levels. Although these shifts are often attributed to refeeding syndrome (RFS), the incidence of electrolyte shifts among patients with IF is unknown. We evaluated the occurrence of hypophosphatemia and other electrolyte shifts according to the functional and pathophysiological IF classifications. METHODS: We consecutively included all patients' first admission to an IF unit from 2013 to 2017. Electrolyte shifts were defined as severe hypophosphatemia <0.6 mmol/L (mM) or any 2 other shifts below reference range, comprising hypomagnesemia <0.75 mM, hypophosphatemia <0.8 mM, or hypokalemia <3.5 mM. Outcomes included length of stay, central line-associated bloodstream infection, and other infections. Mortality was evaluated 6 months after discharge. RESULTS: Of 236 patients with IF, electrolyte shifts occurred in 99 (42%), and 127 (54%) of these patients received intravenous supplementation with either phosphate, magnesium, or potassium. In patients who started parenteral nutrition, up to 62% of early-onset shifts (<5 days) related to refeeding, and up to 63% of late-onset shifts (≥5 days) could be ascribed to infections. Derangements occurred in 7 (18%) with type 1 IF, 53 (43%) with type 2 IF, and 39 (53%) readmitted patients with type 3 IF. Of 133 patients with IF secondary to short-bowel syndrome, 65 (49%) developed shifts. CONCLUSION: In patients with IF, electrolyte shifts are frequent but not always due to RFS. Electrolyte shifts are common in patients with type 2 and those readmitted with type 3 IF.

BACKGROUND: International dietary recommendations include guidance on healthy eating and weight management for people who have survived cancer; however dietary interventions are not provided routinely for people living beyond cancer. OBJECTIVES: To assess the effects of dietary interventions for adult cancer survivors on morbidity and mortality, changes in dietary behaviour, body composition, health-related quality of life, and clinical measurements. SEARCH METHODS: We ran searches on 18 September 2019 and searched the Cochrane Central Register of Controlled trials (CENTRAL), in the Cochrane Library; MEDLINE via Ovid; Embase via Ovid; the Allied and Complementary Medicine Database (AMED); the Cumulative Index to Nursing and Allied Health Literature (CINAHL); and the Database of Abstracts of Reviews of Effects (DARE). We searched other resources including reference lists of retrieved articles, other reviews on the topic, the International Trials Registry for ongoing trials, metaRegister, Physicians Data Query, and appropriate websites for ongoing trials. We searched conference abstracts and WorldCat for dissertations. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that recruited people following a cancer diagnosis. The intervention was any dietary advice provided by any method including group sessions, telephone instruction, written materials, or a web-based approach. We included comparisons that could be usual care or written information, and outcomes measured included overall survival, morbidities, secondary malignancies, dietary changes, anthropometry, quality of life (QoL), and biochemistry. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures. Two people independently assessed titles and full-text articles, extracted data, and assessed risk of bias. For analysis, we used a random-effects statistical model for all meta-analyses, and the GRADE approach to rate the certainty of evidence, considering limitations, indirectness, inconsistencies, imprecision, and bias. MAIN RESULTS: We included 25 RCTs involving 7259 participants including 977 (13.5%) men and 6282 (86.5%) women. Mean age reported ranged from 52.6 to 71 years, and range of age of included participants was 23 to 85 years. The trials reported 27 comparisons and included participants who had survived breast cancer (17 trials), colorectal cancer (2 trials), gynaecological cancer (1 trial), and cancer at mixed sites (5 trials). For overall survival, dietary intervention and control groups showed little or no difference in risk of mortality (hazard ratio (HR) 0.98, 95% confidence interval (CI) 0.77 to 1.23; 1 study; 3107 participants; low-certainty evidence). For secondary malignancies, dietary interventions versus control trials reported little or no difference (risk ratio (RR) 0.99, 95% CI 0.84 to 1.15; 1 study; 3107 participants; low-certainty evidence). Co-morbidities were not measured in any included trials. Subsequent outcomes reported after 12 months found that dietary interventions versus control probably make little or no difference in energy intake at 12 months (mean difference (MD) -59.13 kcal, 95% CI -159.05 to 37.79; 5 studies; 3283 participants; moderate-certainty evidence). Dietary interventions versus control probably led to slight increases in fruit and vegetable servings (MD 0.41 servings, 95% CI 0.10 to 0.71; 5 studies; 834 participants; moderate-certainty evidence); mixed results for fibre intake overall (MD 5.12 g, 95% CI 0.66 to 10.9; 2 studies; 3127 participants; very low-certainty evidence); and likely improvement in Diet Quality Index (MD 3.46, 95% CI 1.54 to 5.38; 747 participants; moderate-certainty evidence). For anthropometry, dietary intervention versus control probably led to a slightly decreased body mass index (BMI) (MD -0.79 kg/m², 95% CI -1.50 to -0.07; 4 studies; 777 participants; moderate-certainty evidence). Dietary interventions versus control probably had little or no effect on waist-to-hip ratio (MD -0.01, 95% CI -0.04 to 0.02; 2 studies; 106 participants; low-certainty evidence). For QoL, there were mixed results; several different quality assessment tools were used and evidence was of low to very low-certainty. No adverse events were reported in any of the included studies. AUTHORS' CONCLUSIONS: Evidence demonstrated little effects of dietary interventions on overall mortality and secondary cancers. For comorbidities, no evidence was identified. For nutritional outcomes, there was probably little or no effect on energy intake, although probably a slight increase in fruit and vegetable intake and Diet Quality Index. Results were mixed for fibre. For anthropometry, there was probably a slight decrease in body mass index (BMI) but probably little or no effect on waist-to-hip ratio. For QoL, results were highly varied. Additional high-quality research is needed to examine the effects of dietary interventions for different cancer sites, and to evaluate important outcomes including comorbidities and body composition. Evidence on new technologies used to deliver dietary interventions was limited.

BACKGROUND: Radical cystectomy (RC) is the primary surgical treatment for muscle-invasive urothelial carcinoma of the bladder. This major operation is typically associated with an extended hospital stay, a prolonged recovery period and potentially major complications. Nutritional interventions are beneficial in some people with other types of cancer and may be of value in this setting too. OBJECTIVES: To assess the effects of perioperative nutrition in people undergoing radical cystectomy for the treatment of bladder cancer. SEARCH METHODS: We performed a comprehensive search using multiple databases (Evidence Based Medicine Reviews, MEDLINE, Embase, AMED, CINAHL), trials registries, other sources of grey literature, and conference proceedings published up to 22 February 2019, with no restrictions on the language or status of publication. SELECTION CRITERIA: We included parallel-group randomised controlled trials (RCTs) of adults undergoing RC for bladder cancer. The intervention was any perioperative nutrition support. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion, extracted data, and assessed risk of bias and the quality of evidence using GRADE. Primary outcomes were postoperative complications at 90 days and length of hospital stay. The secondary outcome was mortality up to 90 days after surgery. When 90-day outcome data were not available, we reported 30-day data. MAIN RESULTS: The search identified eight trials including 500 participants. Six trials were conducted in the USA and two in Europe.1. Parenteral nutrition (PN) versus oral nutrition: based on one study with 157 participants, PN may increase postoperative complications within 30 days (risk ratio (RR) 1.40, 95% confidence interval (CI) 1.07 to 1.82; low-quality evidence). We downgraded the quality of evidence for serious study limitations (unclear risk of selection, performance and selective reporting bias) and serious imprecision. This corresponds to 198 more complications per 1000 participants (95% CI 35 more to 405 more). Length of hospital stay may be similar (mean difference (MD) 0.5 days higher, CI not reported; low-quality evidence).2. Immuno-enhancing nutrition versus standard nutrition: based on one study including 29 participants, immuno-enhancing nutrition may reduce 90-day postoperative complications (RR 0.31, 95% CI 0.08 to 1.23; low-quality evidence). These findings correspond to 322 fewer complications per 1000 participants (95% CI 429 fewer to 107 more). Length of hospital stay may be similar (MD 0.20 days, 95% CI 1.69 lower to 2.09 higher; low-quality evidence). We downgraded the quality of evidence of both outcomes for very serious imprecision.3. Preoperative oral nutritional support versus normal diet: based on one study including 28 participants, we are very uncertain if preoperative oral supplements reduces postoperative complications. We downgraded quality for serious study limitations (unclear risk of selection, performance, attrition and selective reporting bias) and very serious imprecision. The study did not report on length of hospital stay.4. Early postoperative feeding versus standard postoperative management: based on one study with 102 participants, early postoperative feeding may increase postoperative complications (very low-quality evidence) but we are very uncertain of this finding. We downgraded the quality of evidence for serious study limitations (unclear risk of selection and performance bias) and very serious imprecision. Length of hospital stay may be similar (MD 0.95 days less, CI not reported; low-quality evidence). We downgraded the quality of evidence for serious study limitations (unclear risk of selection and performance bias) and serious imprecision.5. Amino acid with dextrose versus dextrose: based on two studies with 104 participants, we are very uncertain whether amino acids reduce postoperative complications (very low-quality evidence). We are also very uncertain whether length of hospital stay is similar (very low-quality evidence). We downgraded the quality of evidence for both outcomes for serious study limitations (unclear and high risk of selection bias; unclear risk of performance, detection and selective reporting bias), serious indirectness related to the patient population and very serious imprecision.6. Branch chain amino acids versus dextrose only: based on one study including 19 participants, we are very uncertain whether complication rates are similar (very low-quality evidence). We downgraded the quality of evidence for serious study limitations (unclear risk of selection, performance, detection, attrition and selective reporting bias), serious indirectness related to the patient population and very serious imprecision. The study did not report on length of hospital stay.7. Perioperative oral nutritional supplements versus oral multivitamin and mineral supplement: based on one study with 61 participants, oral supplements compared to a multivitamin and mineral supplement may slightly decrease postoperative complications (low-quality evidence). These findings correspond to 135 fewer occurrences per 1000 participants (95% CI 256 fewer to 65 more). Length of hospital stay may be similar (low-quality evidence). We downgraded the quality of evidence of both outcomes for study limitations and imprecision. AUTHORS' CONCLUSIONS: Based on few, small and dated studies, with serious methodological limitations, we found limited evidence for a benefit of perioperative nutrition interventions. We rated the quality of evidence as low or very low, which underscores the urgent need for high-quality research studies to better inform nutritional support interventions for people undergoing surgery for bladder cancer.

BACKGROUND & AIMS: Intestinal failure (IF) is defined as "the reduction of gut function below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that intravenous supplementation is required to maintain health and/or growth". Functionally, it may be classified as type I acute intestinal failure (AIF), type II prolonged AIF and type III chronic intestinal failure (CIF) The ESPEN Workshop on IF was held in Bologna, Italy, on 15-16 October 2017 and the aims of this document were to highlight the current state of the art and future directions for research in IF. METHODS: This paper represents the opinion of experts in the field, based on current evidence. It is not a formal review, but encompasses the current evidence, with emphasis on epidemiology, classification, diagnosis and management. RESULTS: IF is the rarest form of organ failure and can result from a variety of conditions that affect gastrointestinal anatomy and function adversely. Assessment, diagnosis, and short and long-term management involves a multidisciplinary team with diverse expertise in the field that aims to reduce complications, increase life expectancy and improve quality of life in patients. CONCLUSIONS: Both AIF and CIF are relatively rare conditions and most of the published work presents evidence from small, single-centre studies. Much remains to be investigated to improve the diagnosis and management of IF and future studies should rely on multidisciplinary, multicentre and multinational collaborations that gather data from large cohorts of patients. Emphasis should also be placed on partnership with patients, carers and government agencies in order to improve the quality of research that focuses on patient-centred outcomes that will help to improve both outcomes and quality of life in patients with this devastating condition.

We recommend that intestinal failure associated liver disease (IFALD) should be diagnosed by the presence of abnormal liver function tests and/or evidence of radiological and/or histological liver abnormalities occurring in an individual with IF, in the absence of another primary parenchymal liver pathology (e.g. viral or autoimmune hepatitis), other hepatotoxic factors (e.g. alcohol/medication) or biliary obstruction. The presence or absence of sepsis should be noted, along with the duration of PN administration. Abnormal liver histology is not mandatory for a diagnosis of IFALD and the decision to perform a liver biopsy should be made on a case-by-case basis, but should be particularly considered in those with a persistent abnormal conjugated bilirubin in the absence of intra or extra-hepatic cholestasis on radiological imaging and/or persistent or worsening hyperbilirubinaemia despite resolution of any underlying sepsis and/or any clinical or radiological features of chronic liver disease. Nutritional approaches aimed at minimising PN overfeeding and optimising oral/enteral nutrition should be instituted to prevent and/or manage IFALD. We further recommend that the lipid administered is limited to less than 1 g/kg/day, and the prescribed omega-6/omega-3 PUFA ratio is reduced wherever possible. For patients with any evidence of progressive hepatic fibrosis or overt liver failure, combined intestinal and liver transplantation should be considered.

Intestinal failure (IF) is the inability of the gut to absorb necessary water, macronutrients (carbohydrate, protein, and fat), micronutrients, and electrolytes sufficient to sustain life and requiring intravenous supplementation or replacement. Acute IF (types 1 and 2) is the initial phase of the illness and may last for weeks to a few months, and chronic IF (type 3) from months to years. The challenge of caring for patients with IF is not merely the management of the underlying condition leading to IF or the correct provision of appropriate nutrition or both but also the prevention of complications, whether thromboembolic phenomenon (for example, venous occlusion), central venous catheter-related bloodstream infection, IF-associated liver disease, or metabolic bone disease. This review looks at recent questions regarding chronic IF (type 3), its diagnosis and management, the role of the multidisciplinary team, and novel therapies, including hormonal treatment for short bowel syndrome but also surgical options for intestinal lengthening and intestinal transplant.
RESUMO
BACKGROUND: An increasing number of people survive cancer but a significant proportion have gastrointestinal side effects as a result of radiotherapy (RT), which impairs their quality of life (QoL). OBJECTIVES: To determine which prophylactic interventions reduce the incidence, severity or both of adverse gastrointestinal effects among adults receiving radiotherapy to treat primary pelvic cancers. SEARCH METHODS: We conducted searches of CENTRAL, MEDLINE, and Embase in September 2016 and updated them on 2 November 2017. We also searched clinical trial registries. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of interventions to prevent adverse gastrointestinal effects of pelvic radiotherapy among adults receiving radiotherapy to treat primary pelvic cancers, including radiotherapy techniques, other aspects of radiotherapy delivery, pharmacological interventions and non-pharmacological interventions. Studies needed a sample size of 20 or more participants and needed to evaluate gastrointestinal toxicity outcomes. We excluded studies that evaluated dosimetric parameters only. We also excluded trials of interventions to treat acute gastrointestinal symptoms, trials of altered fractionation and dose escalation schedules, and trials of pre- versus postoperative radiotherapy regimens, to restrict the vast scope of the review. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodology. We used the random-effects statistical model for all meta-analyses, and the GRADE system to rate the certainty of the evidence. MAIN RESULTS: We included 92 RCTs involving more than 10,000 men and women undergoing pelvic radiotherapy. Trials involved 44 different interventions, including radiotherapy techniques (11 trials, 4 interventions/comparisons), other aspects of radiotherapy delivery (14 trials, 10 interventions), pharmacological interventions (38 trials, 16 interventions), and non-pharmacological interventions (29 trials, 13 interventions). Most studies (79/92) had design limitations. Thirteen studies had a low risk of bias, 50 studies had an unclear risk of bias and 29 studies had a high risk of bias. Main findings include the following:Radiotherapy techniques: Intensity-modulated radiotherapy (IMRT) versus 3D conformal RT (3DCRT) may reduce acute (risk ratio (RR) 0.48, 95% confidence interval (CI) 0.26 to 0.88; participants = 444; studies = 4; I2 = 77%; low-certainty evidence) and late gastrointestinal (GI) toxicity grade 2+ (RR 0.37, 95% CI 0.21 to 0.65; participants = 332; studies = 2; I2 = 0%; low-certainty evidence). Conformal RT (3DCRT or IMRT) versus conventional RT reduces acute GI toxicity grade 2+ (RR 0.57, 95% CI 0.40 to 0.82; participants = 307; studies = 2; I2 = 0%; high-certainty evidence) and probably leads to less late GI toxicity grade 2+ (RR 0.49, 95% CI 0.22 to 1.09; participants = 517; studies = 3; I2 = 44%; moderate-certainty evidence). When brachytherapy (BT) is used instead of external beam radiotherapy (EBRT) in early endometrial cancer, evidence indicates that it reduces acute GI toxicity (grade 2+) (RR 0.02, 95% CI 0.00 to 0.18; participants = 423; studies = 1; high-certainty evidence).Other aspects of radiotherapy delivery: There is probably little or no difference in acute GI toxicity grade 2+ with reduced radiation dose volume (RR 1.21, 95% CI 0.81 to 1.81; participants = 211; studies = 1; moderate-certainty evidence) and maybe no difference in late GI toxicity grade 2+ (RR 1.02, 95% CI 0.15 to 6.97; participants = 107; studies = 1; low-certainty evidence). Evening delivery of RT may reduce acute GI toxicity (diarrhoea) grade 2+ during RT compared with morning delivery of RT (RR 0.51, 95% CI 0.34 to 0.76; participants = 294; studies = 2; I2 = 0%; low-certainty evidence). There may be no difference in acute (RR 2.22, 95% CI 0.62 to 7.93, participants = 110; studies = 1) and late GI toxicity grade 2+ (RR 0.44, 95% CI 0.12 to 1.65; participants = 81; studies = 1) between a bladder volume preparation of 1080 mls and that of 540 mls (low-certainty evidence). Low-certainty evidence on balloon and hydrogel spacers suggests that these interventions for prostate cancer RT may make little or no difference to GI outcomes.Pharmacological interventions: Evidence for any beneficial effects of aminosalicylates, sucralfate, amifostine, corticosteroid enemas, bile acid sequestrants, famotidine and selenium is of a low or very low certainty. However, evidence on certain aminosalicylates (mesalazine, olsalazine), misoprostol suppositories, oral magnesium oxide and octreotide injections suggests that these agents may worsen GI symptoms, such as diarrhoea or rectal bleeding.Non-pharmacological interventions: Low-certainty evidence suggests that protein supplements (RR 0.23, 95% CI 0.07 to 0.74; participants = 74; studies = 1), dietary counselling (RR 0.04, 95% CI 0.00 to 0.60; participants = 74; studies = 1) and probiotics (RR 0.43, 95% CI 0.22 to 0.82; participants = 923; studies = 5; I2 = 91%) may reduce acute RT-related diarrhoea (grade 2+). Dietary counselling may also reduce diarrhoeal symptoms in the long term (at five years, RR 0.05, 95% CI 0.00 to 0.78; participants = 61; studies = 1). Low-certainty evidence from one study (108 participants) suggests that a high-fibre diet may have a beneficial effect on GI symptoms (mean difference (MD) 6.10, 95% CI 1.71 to 10.49) and quality of life (MD 20.50, 95% CI 9.97 to 31.03) at one year. High-certainty evidence indicates that glutamine supplements do not prevent RT-induced diarrhoea. Evidence on various other non-pharmacological interventions, such as green tea tablets, is lacking.Quality of life was rarely and inconsistently reported across included studies, and the available data were seldom adequate for meta-analysis. AUTHORS' CONCLUSIONS: Conformal radiotherapy techniques are an improvement on older radiotherapy techniques. IMRT may be better than 3DCRT in terms of GI toxicity, but the evidence to support this is uncertain. There is no high-quality evidence to support the use of any other prophylactic intervention evaluated. However, evidence on some potential interventions shows that they probably have no role to play in reducing RT-related GI toxicity. More RCTs are needed for interventions with limited evidence suggesting potential benefits.

BACKGROUND: Pre-operative weight loss has been consistently associated with increased post-operative morbidity. The study aims to determine if pre-operative oral nutritional supplements (ONSs) with dietary advice reduce post-operative complications. METHODS: Single-blinded randomized controlled trial. People with colorectal cancer scheduled for surgery with pre-operative weight loss >1 kg/3-6 months were randomized by using stratified blocks (1:1 ratio) in six hospitals (1 November 2013-28 February 2015). Intervention group was given 250 mL/day ONS (10.1 KJ and 0.096 g protein per mL) and dietary advice. Control group received dietary advice alone. Oral nutritional supplements were administered from diagnosis to the day preceding surgery. Research team was masked to group allocation. Primary outcome was patients with one or more surgical site infection (SSI) or chest infection; secondary outcomes included percentage weight loss, total complications, and body composition measurements. Intention-to-treat analysis was performed with both unadjusted and adjusted analyses. A sample size of 88 was required. RESULTS: Of 101 participants, (55 ONS, 46 controls) 97 had surgery. In intention-to-treat analysis, there were 21/45 (47%) patients with an infection-either an SSI or chest infection in the control group vs. 17/55 (30%) in the ONS group. The odds ratio of a patient incurring either an SSI or chest infection was 0.532 (P = 0.135 confidence interval 0.232 to 1.218) in the unadjusted analysis and when adjusted for random differences at baseline (age, gender, percentage weight loss, and cancer staging) was 0.341 (P = 0.031, confidence interval 0.128 to 0.909). Pre-operative percentage weight loss at the first time point after randomization was 4.1% [interquartile range (IQR) 1.7-7.0] in ONS group vs. 6.7% (IQR 2.6-10.8) in controls (Mann-Whitney U P = 0.021) and post-operatively was 7.4% (IQR 4.3-10.0) in ONS group vs. 10.2% (IQR 5.1-18.5) in controls (P = 0.016). CONCLUSIONS: Compared with dietary advice alone, ONS resulted in patients having fewer infections and less weight loss following surgery for colorectal cancer. We have demonstrated that pre-operative oral nutritional supplementation can improve clinical outcome in weight losing patients with colorectal cancer.

BACKGROUND: Catheter-related bloodstream infections (CRBSIs) are a serious complication in the provision of home parenteral nutrition (HPN). Antibiotic salvage of central venous catheters (CVCs) in CRBSI is recommended; however, this is based on limited reports. We assessed the efficacy of antibiotic salvage of CRBSIs in HPN patients. MATERIALS AND METHODS: All confirmed CRBSIs occurring in patients receiving HPN in a national intestinal failure unit (IFU), between 1993 and 2011, were analyzed. A standardized protocol involving antibiotic and urokinase CVC locks and systemic antibiotics was used. RESULTS: In total, 588 patients were identified with a total of 2134 HPN years, and 297 CRBSIs occurred in 137 patients (65 single and 72 multiple CRBSIs). The overall rate of CRBSI in all patients was 0.38 per 1000 catheter days. Most (87.9%) infections were attributable to a single microorganism. In total, 72.5% (180/248) of CRBSIs were salvaged when attempted (coagulase-negative staphylococcus, 79.8% [103/129], Staphylococcus aureus, 56.7% [17/30]; polymicrobial infections, 67.7% [21/30]; and miscellaneous, 66.1% [39/59]). CVC salvage was not attempted in 49 episodes because of life-threatening sepsis (n = 18), fungal infection (n = 7), catheter problems (n = 20), and CVC tunnel infection (n = 4). Overall, the CVC was removed in 33.7% (100/297) of cases. There were 5 deaths in patients admitted to the IFU for management of the CRBSI (2 severe sepsis at presentation, 3 metastatic infection). CONCLUSIONS: This is the largest reported series of catheter salvage in CRBSIs and demonstrates successful catheter salvage in most cases when using a standardized protocol.

Inflammatory bowel disease and Crohn's disease in particular, is a common cause of intestinal failure. Current therapeutic options include home parenteral nutrition and intestinal transplantation. For most patients, home intravenous therapy including parenteral nutrition, with a good probability of long-term survival, is the favoured choice. However, in selected patients, with specific features that may shorten survival or complicate home parenteral nutrition, intestinal transplantation presents a viable alternative. We present survival, complications, quality of life and economic considerations that currently influence individualised decision-making between home parenteral nutrition and intestinal transplantation.

BACKGROUND: Experimental evidence suggests the endogenous cannabinoid system may protect against colonic inflammation, leading to the possibility that activation of this system may have a therapeutic role in inflammatory bowel disease (IBD). Medicinal use of cannabis for chronic pain and other symptoms has been reported in a number of medical conditions. We aimed to evaluate cannabis use in patients with IBD. METHODS: One hundred patients with ulcerative colitis (UC) and 191 patients with Crohn's disease (CD) attending a tertiary-care outpatient clinic completed a questionnaire regarding current and previous cannabis use, socioeconomic factors, disease history and medication use, including complimentary alternative medicines. Quality of life was assessed using the short-inflammatory bowel disease questionnaire. RESULTS: A comparable proportion of UC and CD patients reported lifetime [48/95 (51%) UC vs. 91/189 (48%) CD] or current [11/95 (12%) UC vs. 30/189 (16%) CD] cannabis use. Of lifetime users, 14/43 (33%) UC and 40/80 (50%) CD patients have used it to relieve IBD-related symptoms, including abdominal pain, diarrhoea and reduced appetite. Patients were more likely to use cannabis for symptom relief if they had a history of abdominal surgery [29/48 (60%) vs. 24/74 (32%); P=0.002], chronic analgesic use [29/41 (71%) vs. 25/81 (31%); P<0.001], complimentary alternative medicine use [36/66 (55%) vs. 18/56 (32%); P=0.01] and a lower short inflammatory bowel disease questionnaire score (45.1±2.1 vs. 50.3±1.5; P=0.03). Patients who had used cannabis [60/139 (43%)] were more likely than nonusers [13/133 (10%); P<0.001 vs. users] to express an interest in participating in a hypothetical therapeutic trial of cannabis for IBD. CONCLUSION: Cannabis use is common amongst patients with IBD for symptom relief, particularly amongst those with a history of abdominal surgery, chronic abdominal pain and/or a low quality of life index. The therapeutic benefits of cannabinoid derivatives in IBD may warrant further exploration.

Colorectal cancer screening can be performed by fecal occult blood testing, sigmoidoscopy, double contrast barium enema or colonoscopy. Colonoscopy has the significant advantage that polyps can be removed during the same procedure. Occasionally, colonoscopy can also reveal unexpected findings, including parasitic infections, even in asymptomatic patients. Tapeworms or cestodes are hermaphroditic parasites, which can live for considerable periods of time in the human gastrointestinal tract. Fish tapeworm (Diphyllobothrium species) are endemic in various parts of the world, the commonest species being Diphyllobothrium latum. Humans are the main definitive host for D. Latum and the majority of individuals harbouring the parasite are asymptomatic, while 40% of infected individuals may have low vitamin B12 levels. We describe a case of D. latum infection found on routine colonoscopic screening for colorectal cancer in an asymptomatic patient, which was successfully treated with praziquantel. The infection likely arose following raw fish (sushi) consumption.
