Review
BACKGROUND
The management of patients with enterocutaneous fistula (ECF) requires an interdisciplinary approach and poses a significant challenge to physicians, wound/stoma care specialists, dietitians, pharmacists, and other nutrition clinicians. Guidelines for optimizing nutrition status in these patients are often vague, based on limited and dated clinical studies, and typically rely on individual institutional or clinician experience. Specific nutrient requirements, appropriate route of feeding, role of immune-enhancing formulas, and use of somatostatin analogues in the management of patients with ECF are not well defined. The purpose of this clinical guideline is to develop recommendations for the nutrition care of adult patients with ECF.
METHODS
A systematic review of the best available evidence to answer a series of questions regarding clinical management of adults with ECF was undertaken and evaluated using concepts adopted from the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group. An anonymous consensus process was used to develop the clinical guideline recommendations prior to peer review and approval by the ASPEN Board of Directors and by FELANPE.
QUESTIONS
In adult patients with enterocutaneous fistula: (1) What factors best describe nutrition status? (2) What is the preferred route of nutrition therapy (oral diet, enteral nutrition, or parenteral nutrition)? (3) What protein and energy intake provide best clinical outcomes? (4) Is fistuloclysis associated with better outcomes than standard care? (5) Are immune-enhancing formulas associated with better outcomes than standard formulas? (6) Does the use of somatostatin or somatostatin analogue provide better outcomes than standard medical therapy? (7) When is home parenteral nutrition support indicated?

BACKGROUND & AIMS
This position paper summarizes theoretical and practical aspects of the monitoring of artificial nutrition and metabolism in critically ill patients, thereby completing ESPEN guidelines on intensive care unit (ICU) nutrition.
METHODS
Available literature and personal clinical experience on monitoring of nutrition and metabolism was systematically reviewed by the ESPEN group for ICU nutrition guidelines.
RESULTS
We did not identify any studies comparing outcomes with monitoring versus not monitoring nutrition therapy. The potential for abnormal values to be associated with harm was clearly recognized. The necessity to create locally adapted standard operating procedures (SOPs) for follow up of enteral and parenteral nutrition is emphasised. Clinical observations, laboratory parameters (including blood glucose, electrolytes, triglycerides, liver tests), and monitoring of energy expenditure and body composition are addressed, focusing on prevention, and early detection of nutrition-related complications.
CONCLUSION
Understanding and defining risks and developing local SOPs are critical to reduce specific risks.

Clinical Nutrition (Edinburgh, Scotland) Apr 2017The ESPEN guideline presents a multidisciplinary focus on clinical nutrition in inflammatory bowel disease (IBD). (Review)
Review
INTRODUCTION
The ESPEN guideline presents a multidisciplinary focus on clinical nutrition in inflammatory bowel disease (IBD).
METHODOLOGY
The guideline is based on extensive systematic review of the literature, but relies on expert opinion when objective data were lacking or inconclusive. The conclusions and 64 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required.
RESULTS
IBD is increasingly common and potential dietary factors in its aetiology are briefly reviewed. Malnutrition is highly prevalent in IBD - especially in Crohn's disease. Increased energy and protein requirements are observed in some patients. The management of malnutrition in IBD is considered within the general context of support for malnourished patients. Treatment of iron deficiency (parenterally if necessary) is strongly recommended. Routine provision of a special diet in IBD is not however supported. Parenteral nutrition is indicated only when enteral nutrition has failed or is impossible. The recommended perioperative management of patients with IBD undergoing surgery accords with general ESPEN guidance for patients having abdominal surgery. Probiotics may be helpful in UC but not Crohn's disease. Primary therapy using nutrition to treat IBD is not supported in ulcerative colitis, but is moderately well supported in Crohn's disease, especially in children where the adverse consequences of steroid therapy are proportionally greater. However, exclusion diets are generally not recommended and there is little evidence to support any particular formula feed when nutritional regimens are constructed.
CONCLUSIONS
Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 64 recommendations, of which 9 are very strong recommendations (grade A), 22 are strong recommendations (grade B) and 12 are based only on sparse evidence (grade 0); 21 recommendations are good practice points (GPP).

Meta-Analysis Review
BACKGROUND
Enterocutaneous fistula (ECF) is an abnormal communication between the gastrointestinal tract and skin, with a myriad of etiologies and therapeutic options. Management is influenced by etiology and specifics of the ECF, and patient-related factors. The aim of this study was to assess overall success, recurrence, and mortality rates of treatment for ECF.
MATERIALS
A systematic search of PubMed and Google Scholar was performed through October 2021 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Case reports, reviews, animal studies, studies not reporting outcomes, had no available English text, included patients < 16 years old or those assessing other abdominocutaneous/internal fistulas were excluded.
RESULTS
Fifty-three studies, between 1975 and 2020, incorporating 3078 patients were included. Patient age ranged between 16 and 87 years with a male:female ratio of 1.14:1. ECF developed postoperatively in 89.4%. Other common etiologies were inflammatory bowel disease, trauma, malignancy, and radiation. At least 28% of patients had complex fistulae (reported in 18 studies). Most common fistula site was small bowel. In 34 publications, 62.4% (n = 1371) patients received parenteral nutrition. In 45 publications, 72.5% underwent surgery to treat the fistula. Meta-analysis revealed an 89% healing rate; recurrence rate after initial successful treatment was 11.1%, and mortality rate was 8.5%. In a subgroup of patients who underwent combined ECF takedown and abdominal wall reconstructions (n = 315), 78% achieved fascial closure, mesh was used in 72%, hernia, and fistula recurrence rates were 19.7% and 7.6%, respectively.
CONCLUSIONS
Treatment of ECF must be individualized according to specific etiology and location of the fistula and the patient's associated conditions.

Journal of Clinical Oncology : Official... Jul 2020To provide evidence-based guidance on the clinical management of cancer cachexia in adult patients with advanced cancer.
PURPOSE
To provide evidence-based guidance on the clinical management of cancer cachexia in adult patients with advanced cancer.
METHODS
A systematic review of the literature collected evidence regarding nutritional, pharmacologic, and other interventions, such as exercise, for cancer cachexia. PubMed and the Cochrane Library were searched for randomized controlled trials (RCTs) and systematic reviews of RCTs published from 1966 through October 17, 2019. ASCO convened an Expert Panel to review the evidence and formulate recommendations.
RESULTS
The review included 20 systematic reviews and 13 additional RCTs. Dietary counseling, with or without oral nutritional supplements, was reported to increase body weight in some trials, but evidence remains limited. Pharmacologic interventions associated with improvements in appetite and/or body weight include progesterone analogs and corticosteroids. The other evaluated interventions either had no benefit or insufficient evidence of benefit to draw conclusions on efficacy. Limitations of the evidence include high drop-out rates, consistent with advanced cancer, as well as variability across studies in outcomes of interest and methods for outcome assessment.
RECOMMENDATIONS
Dietary counseling may be offered with the goals of providing patients and caregivers with advice for the management of cachexia. Enteral feeding tubes and parenteral nutrition should not be used routinely. In the absence of more robust evidence, no specific pharmacological intervention can be recommended as the standard of care; therefore, clinicians may choose not to prescribe medications specifically for the treatment of cancer cachexia. Nonetheless, when it is decided to trial a drug to improve appetite and/or improve weight gain, currently available pharmacologic interventions that may be used include progesterone analogs and short-term (weeks) corticosteroids.

Meta-Analysis Review
BACKGROUND
In cancer patients, weight loss is an ominous sign suggesting disease progression and shortened survival time. As a result, providing nutrition support for cancer patients has been proposed as a logical approach for improving clinical outcomes. Nutrition support can be given to patients through enteral nutrition (EN) or parenteral nutrition (PN). The purpose of the review was to compare the outcomes of PN and EN in cancer patients.
METHODS
A literature search was conducted in Ovid MEDLINE and OLDMEDLINE, Embase Classic and Embase, and Cochrane Central Register of Controlled Trials. Studies were included if over half of the patient population had cancer and reported on any of the following endpoints: the percentage of patients that experienced no infection, nutrition support complications, major complications or mortality. Risk ratios (RR) and 95% confidence intervals (CIs) using Review Manager Version 5.3 were calculated. Primary endpoints were stratified according to type of EN for subgroup analysis, grouping studies into either tube feeding (TF) or standard care (SC). Additionally, another subgroup analysis was conducted comparing studies with protein-energy malnutrition (PEM) patients and studies without PEM patients.
RESULTS
The literature search yielded 674 articles of which 36 were included for the meta-analysis. There were no difference in the endpoints between the two study interventions except that PN resulted in more infection when compared with EN (RR =1.09, 95% CI: 1.01-1.18; P=0.03).
CONCLUSIONS
Other than increased incidence of infection, PN has not resulted in prolonging the survival, increasing nutrition support complications, or major complications when compared with EN in cancer patients.

Meta-Analysis
INTRODUCTION
The prevalence of catheter-associated bloodstream infections (CLABSI) is high and is a severe health problem associated with an increase in mortality and elevated economic costs. There are discrepancies related to the risk factors of CLABSI since the results published are very heterogeneous and there is no synthesis in the description of all the predisposing factors.
OBJECTIVE
We aimed to perform a systematic review and meta-analysis to synthesize and establish the risk factors predisposing to CLABSI reported in the literature.
METHOD
This is a systematic review of observational studies following the PRISMA recommendations. MEDLINE and CINAHL databases were searched for primary studies from 2007 to 2021. The protocol was registered in PROSPERO CRD42018083564.
RESULTS
A total of 654 studies were identified, 23 of which were included in this systematic review. The meta-analysis included 17 studies and 9 risk factors were analyzed (total parenteral nutrition (TPN), chemotherapy, monolumen and bilumen catheters, days of catheterization, immunosuppression, kidney disease and diabetes mellitus) due to the homogeneity of their definitions and measurements. The risk factors found to increase the probability of developing CLABSI were TPN, multilumen devices, chemotherapy treatment, immunosuppression and the number of days of catheterization. On the other hand, monolumen devices presented a lower likelihood of triggering this infection.

Review
BACKGROUND
Enteral nutrition (EN) is recommended as the preferred route for early nutrition therapy in critically ill adults over parenteral nutrition (PN). A recent large randomized controlled trial (RCT) showed no outcome differences between the two routes. The objective of this systematic review was to evaluate the effect of the route of nutrition (EN versus PN) on clinical outcomes of critically ill patients.
METHODS
An electronic search from 1980 to 2016 was performed identifying relevant RCTs. Individual trial data were abstracted and methodological quality of included trials scored independently by two reviewers. The primary outcome was overall mortality and secondary outcomes included infectious complications, length of stay (LOS) and mechanical ventilation. Subgroup analyses were performed to examine the treatment effect by dissimilar caloric intakes, year of publication and trial methodology. We performed a test of asymmetry to assess for the presence of publication bias.
RESULTS
A total of 18 RCTs studying 3347 patients met inclusion criteria. Median methodological score was 7 (range, 2-12). No effect on overall mortality was found (1.04, 95 % CI 0.82, 1.33, P = 0.75, heterogeneity I(2) = 11 %). EN compared to PN was associated with a significant reduction in infectious complications (RR 0.64, 95 % CI 0.48, 0.87, P = 0.004, I(2) = 47 %). This was more pronounced in the subgroup of RCTs where the PN group received significantly more calories (RR 0.55, 95 % CI 0.37, 0.82, P = 0.003, I(2) = 0 %), while no effect was seen in trials where EN and PN groups had a similar caloric intake (RR 0.94, 95 % CI 0.80, 1.10, P = 0.44, I(2) = 0 %; test for subgroup differences, P = 0.003). Year of publication and methodological quality did not influence these findings; however, a publication bias may be present as the test of asymmetry was significant (P = 0.003). EN was associated with significant reduction in ICU LOS (weighted mean difference [WMD] -0.80, 95 % CI -1.23, -0.37, P = 0.0003, I(2) = 0 %) while no significant differences in hospital LOS and mechanical ventilation were observed.
CONCLUSIONS
In critically ill patients, the use of EN as compared to PN has no effect on overall mortality but decreases infectious complications and ICU LOS. This may be explained by the benefit of reduced macronutrient intake rather than the enteral route itself.

Meta-Analysis
BACKGROUND & AIMS
The refeeding syndrome (RFS) has been recognized as a potentially life-threatening metabolic complication of re-nutrition, but the definition widely varies and, its incidence is unknown. The aim of this systematic review and meta-analyses was to estimate the incidence of RFS in adults by considering the definition used by the authors as well as the recent criteria proposed by the American Society of Parenteral and Enteral Nutrition (ASPEN) consensus. Furthermore, the incidence of refeeding hypophosphatemia (RH) was also assessed.
METHODS
Four databases were systematically searched until September 2020 for retrieving trials and observational studies. The incidences of RFS and RH were expressed as percentage and reported with 95% confidence intervals (CI).
RESULTS
Thirty-five observational studies were included in the analysis. The risk of bias was serious in 16 studies and moderate in the remaining 19. The incidence of RFS varied from 0% to 62% across the studies. No substantial change in the originally reported incidence of RFS was found by applying the ASPEN criteria. Similarly, the incidence of RH ranged between 7% and 62%. In the subgroup analyses, inpatients from Intensive Care Units (ICUs) and those initially fed with >20 kcal/kg/day seemed to have a higher incidence of both RFS (pooled incidence = 44%; 95% CI 36%-52%) and RH (pooled incidence = 27%; 95% CI 21%-34%). However, due to the high heterogeneity of data, summary incidence measures are meaningless.
CONCLUSION
The incidence rate of both RFS and RH greatly varied according to the definition used and the population analyzed, being higher in ICU inpatients and in those with increased initial caloric supply. Therefore, a universally accepted definition for RFS, taking different clinical contexts and groups of patients into account, is still needed to better characterize the syndrome and its approach.

Review
OBJECTIVE
Given the importance of weight restoration for recovery in patients with anorexia nervosa (AN), we examined approaches to refeeding in adolescents and adults across treatment settings.
METHODS
Systematic review of PubMed, PsycINFO, Scopus, and Clinical Trials databases (1960-2015) using terms refeeding, weight restoration, hypophosphatemia, anorexia nervosa, anorexia, and anorexic.
RESULTS
Of 948 screened abstracts, 27 met these inclusion criteria: participants had AN; reproducible refeeding approach; weight gain, hypophosphatemia or cognitive/behavioral outcomes. Twenty-six studies (96%) were observational/prospective or retrospective and performed in hospital. Twelve studies published since 2010 examined approaches starting with higher calories than currently recommended (≥1400 kcal/d). The evidence supports 8 conclusions: 1) In mildly and moderately malnourished patients, lower calorie refeeding is too conservative; 2) Both meal-based approaches or combined nasogastric+meals can administer higher calories; 3) Higher calorie refeeding has not been associated with increased risk for the refeeding syndrome under close medical monitoring with electrolyte correction; 4) In severely malnourished inpatients, there is insufficient evidence to change the current standard of care; 5) Parenteral nutrition is not recommended; 6) Nutrient compositions within recommended ranges are appropriate; 7) More research is needed in non-hospital settings; 8) The long-term impact of different approaches is unknown;
DISCUSSION
Findings support higher calorie approaches to refeeding in mildly and moderately malnourished patients under close medical monitoring, however the safety, long-term outcomes, and feasibility outside of hospital have not been established. Further research is also needed on refeeding approaches in severely malnourished patients, methods of delivery, nutrient compositions and treatment settings.
