Micronutrient deficiencies in inflammatory bowel disease: an incidence analysis

BACKGROUND

Micronutrient deficiencies associated with malnutrition in patients with inflammatory bowel disease (IBD) can lead to complications including anemia, coagulopathy, poor wound healing, and colorectal cancer. This study aimed to investigate micronutrient deficiencies (copper, vitamins A, B9, E, and K) in IBD patients and highlight associated symptoms to aid in the recognition of micronutrient deficiencies.

METHODS

A retrospective electronic chart review was performed on adults diagnosed with Crohn's disease or ulcerative colitis hospitalized at a tertiary care center for IBD flare between January 2013 and June 2017. Patients with serum or whole blood micronutrient levels were included. Pregnant and incarcerated patients were excluded.

RESULTS

A total of 611 IBD patients (440 Crohn's disease, 171 ulcerative colitis) met the inclusion criteria. Micronutrients were assessed in a subset of IBD patients (copper: 12.3%, A: 10.1%, B9 : 95.9%, E: 10.3%, and K: 4.6%). Overall, 10.1% of patients had micronutrient deficiencies. The proportion of patients with copper, A, B9, E, and K deficiencies were 25.4, 53.3, 1.9, 23.7, and 29.4% for Crohn's disease and 50, 52.9, 1.2, 43.8, and 18.2% for ulcerative colitis, respectively. The most common symptoms or historical features associated with micronutrient deficiency were anemia (copper, B9), muscle weakness (copper, E) thrombocytopenia, fatigue (copper, B9), diarrhea (B9), dry skin, hyperkeratosis, pruritus, significant weight loss, elevated C-reactive protein (A), bleeding, and osteoporosis (K).

CONCLUSION

Micronutrient deficiencies are common in IBD patients, yet they are not routinely assessed. Copper, vitamins A, E, and K deficiencies are particularly underrecognized. Associated historical features should raise suspicion and prompt assessment and treatment.

Prevention, Assessment, and Management of Malnutrition in Older Adults with Early Stages of Cognitive Disorders

Malnutrition is common in older adults, and its risk is greater in those living with dementia. Relative to cognitively healthy peers, the prevalence of malnutrition is also increased in individuals with early stages of cognitive disorders owing to pathophysiological, cognitive, and psychosocial changes related to cognitive impairment. Malnutrition is associated with adverse health outcomes, including faster cognitive and functional decline. Here, we provide an overview of the prevention, assessment, and management of malnutrition in older adults, with a special focus on the aspects that are important to consider in individuals with early stages of cognitive disorders. Strategies to prevent malnutrition include systematic screening for malnourishment using validated tools to detect those at risk. If the screening reveals an increased risk of malnutrition, a detailed assessment including the individual's nutritional, medical, and functional status as well as dietary intake should be performed. The management of malnutrition in the early stages of cognitive disorders should be based on the findings of a comprehensive assessment and be personalized according to the individual's specific characteristics. In the article, we also provide an overview of the evidence on vitamin supplements and specific dietary patterns to prevent cognitive decline or attenuate its progression.

Survey of dietary beliefs and habits of inflammatory bowel disease patients

BACKGROUND & AIMS

It is presumed that diet plays a role in the prevention and pathogenesis of inflammatory bowel disease (IBD). Patients with Crohn's disease (CD) and ulcerative colitis (UC) often report a link between their disease and diet. However, studies evaluating patient perceptions on diet in IBD are lacking. This study aimed to assess patient beliefs on the role of diet in IBD and the adequacy of dietary advice they received.

METHODS

A self-administered questionnaire was offered to consecutive patients attending two IBD centers in Switzerland. Data were collected regarding patient dietary beliefs and behaviors and whether they received medical advice on their diet.

RESULTS

Of 210 questionnaires distributed, 171 were completed. Participants were mainly female (53%), young (median age 38 years) with either CD (66%) or UC (34%). Most patients believed that diet plays a role in their disease (74%), whereas only 15% believed that diet could be the trigger of their disease. Since their IBD diagnosis, more than half of patients (56%) modified their diet, and 39% did not receive dietary advice from their physicians or a dietician. Most patients (91-95%) ingested gluten, lactose, red and white meat. 20% of patients practiced intermittent fasting and only a minority had previously tried a low-FODMAP (9%) diet or probiotics supplementation (16%).

CONCLUSION

The majority of IBD patients believe that diet plays a role in their disease but have never received dietary advice from their doctor or a dietician. This highlights a need for more information for IBD patients on dietary advice from the medical profession.

Global research trends on diet and nutrition in Crohn’s disease

BACKGROUND

Crohn’s disease represents a challenge for patients concerned with the modified diet regimen as well as practitioners who seek the best nutritional therapy. Crohn’s disease can alter the body’s ability to digest food and to absorb nutrients, resulting in severe vitamin deficiencies, malnutrition and sometimes life-threatening complications. However, a comprehensive bibliometric analysis is lacking to map the current links between nutrition and Crohn’s disease in terms of the number of citations, geographic distribution and growth trends of publications.

AIM

To introduce the current state of research as well as hotspots in the field of nutrition and Crohn’s disease from a bibliometric standpoint.

METHODS

We searched the Scopus database and selected the relevant literature on nutrition and Crohn’s disease that met the inclusion criteria. We analyzed the publication trends and research hotspots by using video object segmentation viewer software.

RESULTS

We included 1237 publications. The number of documents published each year has increased steadily. The United States and the University of Otago, Christchurch, have had the highest productivity, with 208 (16.81%) and 29 (2.34%) documents, respectively. The “role of exclusive enteral nutrition for complicated Crohn’s disease” and “manipulation of the gut microbiota as a key target for Crohn’s disease” were the major research areas in 2016-2021, and they could be extensively investigated in the future. Meanwhile, research on “malnutrition in patients with Crohn’s disease” appeared to be an area that attracted more research attention before 2016.

CONCLUSION

This is the first bibliometric analysis to map the knowledge structure and trends regarding nutrition in Crohn’s disease research over the past two decades. The results provide a comprehensive summary and identification of the frontiers of nutrition and Crohn’s disease-related research, which may be used as a resource by researchers in the field.

ESPEN guideline on Clinical Nutrition in inflammatory bowel disease

The present guideline is an update and extension of the ESPEN scientific guideline on Clinical Nutrition in Inflammatory Bowel Disease published first in 2017. The guideline has been rearranged according to the ESPEN practical guideline on Clinical Nutrition in Inflammatory Bowel Disease published in 2020. All recommendations have been checked and, if needed, revised based on new literature, before they underwent the ESPEN consensus procedure. Moreover, a new chapter on microbiota modulation as a new option in IBD treatment has been added. The number of recommendations has been increased to 71 recommendations in the guideline update. The guideline is aimed at professionals working in clinical practice, either in hospitals or in outpatient medicine, and treating patients with IBD. General aspects of care in patients with IBD, and specific aspects during active disease and in remission are addressed. All recommendations are equipped with evidence grades, consensus rates, short commentaries and links to cited literature.

Präoperatives Ernährungsmanagement in der großen Tumorchirurgie des Bauchraumes an deutschen Kliniken. Eine explorative Strukturanalyse

Bis zu 80% der PatientInnen vor Tumorresektionen des oberen Gastrointestinaltrakts sind mangelernährt. Dabei hat schon der präoperative Ernährungszustand einen signifikanten Einfluss auf den perioperativen Verlauf. Ein adäquater präoperativer Ernährungszustand, der unter anderem die Komplikationsrate und die Krankenhausliegedauer reduzieren kann, ist daher erstrebenswert. Zwar empfehlen einschlägige Leitlinien Maßnahmen zur Erkennung und Behandlung einer Mangelernährung, jedoch fehlt es bislang an Vorschlägen zur Planung eines strukturieren präoperativen Ernährungsmanagements auf die BehandlerInnen zurückgreifen können. Innerhalb dieser Arbeit wurden 40 Krankenhäuser in Deutschland deshalb zu individuell vorhandenen Strukturen und Maßnahmen zum präoperativen Ernährungsmanagement von PatientInnen vor Tumorresektionen des oberen Gastrointestinaltrakts befragt. Die Befragungen zeigen, dass Maßnahmen zur Erkennung und Therapie einer präoperativen Mangelernährung mehrheitlich bekannt und akzeptiert sind. So befürworten 35 der 40 TeilnehmerInnen eine präoperative Ernährungstherapie bei mangelernährten PatientInnen, 26 TeilnehmerInnen erwägen hierfür sogar einen Aufschub der Operation. Eine flächendeckende Umsetzung an den Kliniken scheitere jedoch häufig an Hinderungsgründen, wie fehlender Sichtbarkeit der Ernährung als Therapiebaustein unter BehandlerInnen, labilen Verantwortlichkeiten sowie unzureichenden finanziellen und personellen Ressourcen. Mögliche Lösungsvorschläge zum Abbau der Hindernisse reichen von Refinanzierungsmöglichkeiten der klinischen Ernährungstherapie bis hin zu Forderungen auf gesundheitspolitischer Ebene. Aus den Erkenntnissen aktueller Studien und Leitlinien, sowie den Ergebnissen der Befragung, unterbreitet diese Arbeit einen Vorschlag zur Implementierung eines präoperativen Ernährungsmanagements. Dessen Umsetzbarkeit im klinischen Alltag sollte dabei durch wissenschaftliche Verfahren begleitet werden.

A Nutrition-Related Factor-Based Risk Stratification for Exploring the Clinical Benefits in the Treatment of Patients With Locally Advanced Esophageal Squamous Cell Carcinoma Receiving Definitive Chemoradiotherapy: A Retrospective Cohort Study

Objective

No study has reported the risk stratification of BMI and PNI in patients with locally advanced esophageal squamous cell carcinoma (ESCC) undergoing definitive chemoradiotherapy (dCRT). This study aimed to construct a risk stratification to guide the treatment of ESCC following dCRT.

Methods

A total of 1,068 patients with locally advanced ESCC who received dCRT were retrospectively analyzed. The impacts of clinicopathological factors on overall survival (OS) and progression-free survival (PFS) were analyzed. Besides, the novel prognostic indices of pre-therapeutic nutritional index (PTNI) and prognostic index (PI) were developed.

Results

The median follow-up period of OS and PFS were 22.9 and 17.4 months, respectively. The high body mass index (BMI) group had better 5-year OS and PFS (36.4 and 34.0%) than the low BMI group (18.8 and 17.2%). The high prognostic nutritional index (PNI) group also had better 5-year OS and PFS (33.4 and 30.9%) than the low PNI group (17.5 and 17.2%). Multivariate Cox regression analysis showed that BMI and PNI were independent prognostic factors for OS and PFS. Based on nutritional indices, patients were categorized into the low-risk (PTNI = 1), medium-risk (PTNI = 2), and high-risk (PTNI = 3) groups with 5-year OS rates of 38.5, 18.9, 17.5%, respectively (p < 0.001) and 5-year PFS rates of 35.8, 17.6, 16.8%, respectively (p < 0.001). Besides, we also constructed a prognostic index (PI) for OS and PFS which was calculated based on statistically significant factors for predicting OS and PFS. The results revealed that the high-risk group had worse OS and PFS than the low-risk group (p < 0.001). Finally, RCS analysis demonstrated a non-linear relationship between the PNI, BMI, and survival for patients with ESCC. The death hazard of PNI and BMI sharply decreased to 41.8 and 19.7.

Conclusion

The decreased pre-therapeutic BMI and PNI levels were associated with a worse survival outcome. BMI and PNI are readily available and can be used to stratify risk factors for locally advanced ESCC patients undergoing dCRT. The novel risk stratification may help to evaluate patients’ pre-therapeutic status and guide dCRT for locally advanced ESCC patients.

The Role of the Pharmacist in Selecting the Best Choice of Medication Formulation in Dysphagic Patients

Usually, the administration of drugs by feeding tube in dysphagic patients involves handling of marketing licenses outside their term, due to the lack of suitable formulations. This circumstance has put health professionals in the dilemma of choosing the formulation whose manipulation possibly does not alter the effectiveness of the drug. In this regard, a practical guide providing indications on the prescription, handling, and administration of drugs through enteral feeding tube could be of paramount utility. For this purpose, we have considered the 1047 solid oral pharmaceutical forms included in the formulary of San Paolo Hospital (Savona, Italy). From our analysis, it emerges that 95% of medicinal products are worryingly used off-label and 40% have to be managed by the hospital pharmacists without having suitable indications by either the manufacturers or by literature studies. To fill this gap, we have compiled a detailed table containing missing indications derived from pharmacist expertise and evidence-based practices, with the aim that the sharing of our procedures will contribute to make uniform pharmacological therapies from one hospital to another. This study will allow doctors to have easy access to information on drugs that can be prescribed and nurses to become familiar only with the pharmaceutical forms that can be administered.

Percutaneous endoscopic gastrostomy tube replacement after head and neck surgery: A case report

INTRODUCTION

Percutaneous endoscopic gastrostomy (PEG) has been available since the 1980s. Routine replacement is conducted at bedside with relatively few complications. Two replacement methods have come into practice: the percutaneous method and the endoscopic method. The laparoscopic method has recently become favorable in the pediatric population.

PRESENTATION OF CASE

Herein, we describe a situation in which a gastrostomy tube was replaced at bedside on a patient with previous head and neck surgery for lingual cancer. The percutaneous traction method was used, and gastrostomy tube replacement into the gastric lumen could not be confirmed on subsequent imaging. The patient was ultimately taken to surgery for an open procedure where it was discovered that initial PEG placement had traversed the small bowel mesentery en route to the gastric lumen.

DISCUSSION

The PEG tube is not a permanent device and routine exchange every 6-12 months is recommended. The percutaneous method and endoscopic method for gastrostomy tube replacement have both been used routinely, each with their set of complications. A third technique, laparoscopic placement, is the preferred modality in the pediatric population. Advantages are twofold: direct visualization of the stomach, thus eliminating inadvertent hollow viscus injury, and applicability in infants too small to undergo endoscopy necessary for PEG tube placement.

CONCLUSION

Consideration for laparoscopic placement or replacement in the head and neck cancer patient population, in which interval endoscopy is impossible, is thus advocated.

Secondary Indicators for an Evaluation and Guidance System for Quality of Care in Inflammatory Bowel Disease Centers: A Critical Review of the Inflammatory Bowel Disease Quality of Care Center

The number of patients with inflammatory bowel disease (IBD) has increased remarkably in recent years. However, the level of health care for IBD patients varies greatly among regions of China. Standardization of health care for IBD patients is essential to improve quality of care (QoC). The mission of the IBD Quality Care Evaluation Center (IBDQCC) is to establish indicators for QoC. Since 2017, the IBDQCC has developed structure, process, and outcome indicators with the steering committee of IBD specialists and methodologists; 28 core and 13 secondary IBD QoC indicators were selected using a Delphi method. Applications for certification of IBD quality care units were made voluntarily and preliminarily screened through the IBDQCC committee. Regional units had to meet all core indicators, and units of excellence were required to meet all core indicators together with an additional 50% of secondary indicators. As of 2019 and 2020, 69 IBD units (all from tertiary referral hospitals) have been certified as regional IBD units in China. The certification of excellence of the IBD units is currently undergoing auditing. The awareness of and appreciation for QoC in IBD is increasing in China, especially through the quality control evaluation program initiated by the IBDQCC, with a higher number of IBD units applying for the next round of certification. Although secondary indicators seem to play relatively minor roles in QoC, they suggest additional requirements for high-level centers.

Twelve-week peptide-based formula therapy may be effective in inducing remission of active Crohn disease among women who are pregnant or preparing for pregnancy

BACKGROUND

Conventional treatment for Crohn disease (CD) in pregnancy includes mesalamine, thiopurine, and anti-tumor necrosis factor (TNF)-α agents. However, women may abstain because of complications, nonresponse, or potential adverse outcomes. Peptide-based formula therapy, through oral or nasogastric feeding without other food intake, is an effective and safe therapy for active CD. Herein, We confirmed the effectiveness and safety of peptide-based formula therapy for active CD in pregnant women or those preparing for pregnancy.

METHOD

Outcomes of peptide-based formula therapy to induce CD remission during pregnancy preparation and the conception period were evaluated retrospectively among 14 women. Efficacy was evaluated as the change in serum indices and inflammatory markers after 12-week treatment. Pregnancy outcomes were compared between 14 women treated with nutrition therapy and eight women using conventional CD drugs.

RESULTS

After 12 weeks, 85.7% (12 of 14) of patients treated with peptide-based formula achieved remission with a significant decrease in the CD activity index (P < .001) and high-sensitivity C-reactive protein level (P = .004). There were no effects of peptide-based formula therapy on pregnancy outcomes compared with conventional CD treatment (P > .05). Among the 12 patients who achieved CD remission with exclusive peptide-based formula therapy, 10 selected to continue total or partial peptide-based formula treatment to maintain CD remission throughout pregnancy.

CONCLUSION

Peptide-based formula therapy, without other food intake, may provide a safe and effective alternative to conventional CD drugs to induce disease remission among women during conception and pregnancy.

Post-operative morbidity in Crohn's disease: what is the impact of patient-, disease- and surgery-related factors?

PURPOSE

Over 50% of patients suffering from Crohn's disease (CD) require surgery in their lifetime. Predictors/risk factors of post-operative morbidity and mortality in CD are poorly investigated. We aimed to assess the risk factors of post-operative morbidity/mortality in CD.

METHODS

We performed a retrospective cohort study in which all CD patients operated and followed up at our tertiary Inflammatory Bowel Disease Centre from 2014 to 2019 were enrolled. For each patient, we evaluated patient-dependent, disease-dependent and surgery-dependent variables. All patients underwent small bowel and/or colic resections.

RESULTS

Of the 165 operated patients, forty-two (25.5%) developed post-operative complications (major complication rate = 9.8%) including wound infection (12.1%), respiratory complications (4.8%), prolonged ileum (4.2%), anastomotic leak (3.6%), urinary infections (3%), abdominal abscess (2.4%), anastomotic bleeding (3.6%), abdominal bleeding (1.2%) and obstruction (0.6%). Two subjects (1.2%) required re-operation within 30 days, and one died. A surgery duration < 141 min was predictive of a better post-operative outcome (sensitivity 80.9%, specificity 43.1%, PPV 32.7%, NPV 86.9%). The multivariable analysis showed stricturing/fistulizing behaviour (OR 3.7, 95% CI 1.6-6.4, p = 0.02), need for total parenteral nutrition (OR 4.1, 95% CI 2.4-9.2, p = 0.01), pre-operative bowel cleansing (OR 0.6, 95% CI 0.41-0.83, p = 0.01) and surgery duration < 141 min (OR 0.2, 95% CI 0.08-0.7, p = 0.03) as the only risk factors associated with post-operative morbidities.

CONCLUSIONS

About 25% of CD patients develop post-operative complications. Several patient-related, disease-related and surgery-related factors should be considered risk factors for post-operative morbidity. The recognition of these factors, as well as a multidisciplinary approach to the pre-operative management of CD, could reduce post-operative complications.

Immunity and Nutrition: The Right Balance in Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is an increasingly urgent medical problem that strongly impairs quality of life for patients. A global rise in incidence has been observed over the last few decades, with the highest incidence rates recorded in North America and Europe. Still, an increased incidence has been reported in the last ten years in newly industrialized countries in Asia, including China and India, both with more than one billion inhabitants. These data underline that IBD is an urgent global health problem. In addition, it is estimated that between 20% and 30% of IBD patients will develop colorectal cancer (CRC) within their lifetime and CRC mortality is approximately 50% amongst IBD patients. Although the exact etiology of IBD is still being defined, it is thought to be due to a complex interaction between many factors, including defects in the innate and adaptive immune system; microbial dysbiosis, i.e., abnormal levels of, or abnormal response to, the gastrointestinal microbiome; a genetic predisposition; and several environmental factors. At present, however, it is not fully understood which of these factors are the initiators of inflammation and which are compounders. The purpose of this review is to analyze the complex balance that exists between these elements to maintain intestinal homeostasis and prevent IBD or limit adverse effects on people’s health.

Scheduled percutaneous endoscopic gastrostomy tube replacement did not reduce PEG-related complications

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) tube insertion is used for enteral nutrition. Each manufacturer has its own instructions for planned tube replacement. Accordingly, caregivers have adopted the policy of elective change at a fixed period of time (3-6 months).

AIM

The current study aimed to assess whether retained PEG for more than 6 months was associated with a higher rate of PEG-related complications.

METHODS

A retrospective single-center study included all patients who underwent PEG insertion were included in the study.

RESULTS

Overall, 303 patients were included, 48 patients (16.2%) had PEG tube replacement. Peristomal PEG tube leak was the commonest complication, occurring in 20 patients (41.7%), followed by dislodgement in 18 patients (37.5%) and obstruction in 10 patients (20.8%). Among the patients with a leak, it occurred within and beyond 6 months from PEG insertion in 40 and 60% of patients, respectively (OR 0.68, 95% CI 0.21-2.18, p = .57). Similarly, 50% of patients had PEG tube obstruction within 6 months and 50% had it beyond 6 months from insertion (OR 1.46, 95% CI 0.34-6.26, p = .72). Moreover, there was no difference in PEG dislodgement after PEG insertion within or beyond 6 months (nine patients, 50% vs. nine patients, 50%), respectively, (OR 1.37, 95% CI 0.42-4.47, p = .76).

CONCLUSION

Retained PEG tubes for more than 6-months were not associated with more PEG-tube-related complications.

The effect of enteral stimulation on the immune response of the intestinal mucosa and its application in nutritional support

The intestine plays a fundamental role as a regulator of the mucosal immune response, mostly through the production and secretion of secretory Immunoglobulin A (sIgA) by the gut-associated lymphoid tissue (GALT). Enteral stimulation, a balance between the commensal microbiota and pathogenic microorganisms, in addition to an adequate nutritional status is required for the optimal immune function of the intestine. Fasting subjects or those supported only with parenteral nutrition, show a progressive anatomical and physiological deterioration of the GALT, triggering a series of alterations resulting in a decrease in the intestinal immune response, modification in the type of microbiota, and changes that lead to or aggravate malnutrition. Patients with malnutrition present an increase in the rate of nosocomial infections, hospital length of stay, and mortality. An adequate nutritional assessment at hospital admission and avoiding long periods of fasting are paramount to prevent these unfavorable outcomes. Herein, we present a mini-state of the art review on the role and importance of enteral stimulation by GALT-mediated immune response.

Impact of Branched Chain Amino Acid on Muscle Mass, Muscle Strength, Physical Performance, Combined Survival, and Maintenance of Liver Function Changes in Laboratory and Prognostic Markers on Sarcopenic Patients With Liver Cirrhosis (BCAAS Study): A Randomized Clinical Trial

Background: This study aimed to investigate the long-term effects of branched-chain amino acids (BCAAs) supplementations on the parameters associated with improved prognosis in sarcopenic patients with liver cirrhosis (LC) and evaluate its impact on cirrhotic-related events. Methods: A 24-week, single-center, randomized, open-label, controlled, two cohort parallel-group intervention study was carried out by comparing the efficacy of BCAAs against lactoalbumin (L-ALB) on 106 sarcopenic patients with LC. The BCAA (intervention) group was treated with 7.2 g BCAA per dose, whereas the L-ALB group was treated with 6.3 g of L-ALB. The primary outcome was to assess the effect of BCAA on the parameters of sarcopenia, such as muscle mass, muscle strength, and physical performance. The secondary outcomes were to study the combined survival and maintenance of liver function changes in laboratory and prognostic markers over the duration of 6 months. Results: The treatment with BCAA leads to the significant improvement in sarcopenic parameters, such as muscle strength, muscle function, and muscle mass. The total cirrhotic-related complications and cumulative event-free survival occurred fewer in the BCAA group than in the L-ALB group. In addition, prognostic markers improved significantly in the study. Conclusion: The current study demonstrated that long-term BCAAs supplementation improved sarcopenia and prognostic markers in patients with advanced LC.

"Oral Nutritional Supplements: Sugar Content and Potential Dental Implications"

OBJECTIVES

The objectives of this article are to list the most commonly prescribed Oral Nutritional Supplements in the UK and Ireland and their sugar content; and to raise awareness among the dental profession regarding their uses and potential dental risks involved.

BACKGROUND

Many older patients benefit from Oral Nutritional Supplements. Prescribers may not consider dental implications of these. Patients may not think to disclose these medications to their dentist.

MATERIALS AND METHODS

A list of commonly prescribed Oral Nutritional Supplements in the UK and Ireland was compiled. Nutritional information was obtained from the manufacturers' website and arranged in order of decreasing sugar content. Potential dental implications are discussed and recommendations made for dental practitioners.

RESULTS

Pre-formed Oral Nutritional Supplements can contain between 6.6 and 27.2 g of sugar per serving. Powdered Oral Nutritional Supplements, which are to be mixed with 200 ml whole milk, contain between 16.4 and 35.0 g sugar per serving. The "shot"-type Oral Nutritional Supplements contain less sugar, ranging from 0.0 to 4.0 g per serving.

CONCLUSIONS

The sugar content of frequently prescribed Oral Nutritional Supplements can be high. While they are beneficial in assisting the patient to maintain a healthy BMI, they may increase the risk of dental caries. Dental professionals should enquire specifically about Oral Nutritional Supplements during history taking, particularly in groups who are likely to be prescribed such supplements. Consideration should also be given to increasing caries-preventive measures for patients who take these supplements.

The Risk Factors for Complications After Crohn's Disease Surgery

Background

Crohn's disease needs a multidisciplinary approach, and surgery will ultimately be necessary for most patients. Complications usually occur after surgery.

Objective

This study aims to present complication rates in surgically treated Crohn's disease patients at a single institution and to determine possible risk factors.

Methods

A retrospective analysis of 112 consecutive surgery performed on Crohn's disease patients between 2003 and 2015. The demographic data, patient and disease characteristics, surgery type, and complications were analyzed.

Results

Of 112 patients, 64 (57.1%) were male and 48 (42.9%) were female. The mean age was 34 (range, 18–78) years. The mean follow-up was 114 ± 32.4 (range, 61–197) months. The most common early complications were intra-abdominal abscess formation (n = 10, 8.9%) and wound infection (n = 7, 6.26%). The incisional hernia was the most common late complication (n = 4, 3.6%). Nonmodifiable disease features associated with complications were colonic involvement of the disease (P = 0.001), penetrating disease character (P = 0.037), stoma formation (P = 0.000), fistula (P = 0.008), and concomitant fistula and intra-abdominal abscess existence (P = 0.043). Stoma formation was found to be an independent risk factor for complications (P = 0.001).

Conclusions

Colonic involvement, penetrating disease, fistula, concomitant abscess and fistula, and stoma formation were identified as nonmodifiable risk factors for complications after surgery for Crohn's disease.

Review article: The aetiology of fatigue in inflammatory bowel disease and potential therapeutic management strategies

BACKGROUND

Fatigue is the inability to achieve or maintain an expected work output resulting from central or peripheral mechanisms. The prevalence of inflammatory bowel disease (IBD) fatigue can reach 86% in active disease, persisting in 50%-52% of patients with mild to inactive disease. Fatigue is the commonest reason for work absence in IBD, and patients often report fatigue burden to be greater than that of primary disease symptoms. Relatively few evidence-based treatment options exist, and the aetiology is poorly understood.

AIM

To review the available data and suggest a possible aetiology of IBD fatigue and to consider the efficacy of existing management strategies and highlight potential future interventions.

METHODS

We reviewed fatigue-related literature in IBD using PubMed database.

RESULTS

Disease related factors such as inflammation and pharmacological treatments negatively impact skeletal muscle and brain physiology, likely contributing to fatigue symptoms. Secondary factors such as malnutrition, anaemia, sleep disturbance and psychological comorbidity are potential determinants. Immune profile, faecal microbiota composition and physical fitness differ significantly between fatigued and non-fatigued patients, suggesting these may be aetiological factors. Solution-focused therapy, high-dosage thiamine supplementation and biological therapy may reduce fatigue perception in IBD. The effect of physical activity interventions is inconclusive.

CONCLUSIONS

A multimodal approach is likely required to treat IBD fatigue. Established reversible factors like anaemia, micronutrient deficiencies and active disease should initially be resolved. Psychosocial intervention shows potential efficacy in reducing fatigue perception in quiescent disease. Restoring physical deconditioning by exercise training intervention may further improve fatigue burden.

Gastrointestinal Tolerance and Protein Absorption Markers with a New Peptide Enteral Formula Compared to a Standard Intact Protein Enteral Formula in Critically Ill Patients

The aim of this exploratory study was to investigate gastrointestinal tolerance and protein absorption markers with a new enteral peptide formula (PF) compared to an isocaloric enteral intact protein standard formula (SF) containing the same amount of protein in ICU patients. Patients admitted to a cardio-thoracic intensive care unit expected to receive tube feeding for ≥5 days were randomized to receive either PF (1.5 kcal/mL) or SF in a double-blind manner for ≤14 days. Twenty-six patients were randomized (13 SF and 13 PF) and 23 (12 SF and 11 PF) completed at least 5 days of product administration. There were no statistically significant differences between the feeds during the first 5 days of intervention for diarrhea (SF:3 (23%); PF:5 (39%), p = 0.388), vomiting (SF:1 (8%); PF:2 (15%), p = 0.549), constipation (SF:7 (54%), PF:3 (23%), p = 0.115), and high gastric residual volume (>500 mL: SF:1 (8%); PF: 2 (15%), p = 0.535). There were no differences in plasma amino acids or urinary markers of protein absorption and metabolism. In conclusion, no major differences were found in tolerability and protein absorption markers between the standard intact protein formula and the peptide formula.

Small and Large Intestine (II): Inflammatory Bowel Disease, Short Bowel Syndrome, and Malignant Tumors of the Digestive Tract

The small intestine is key in the digestion and absorption of macro and micronutrients. The large intestine is essential for the absorption of water, to allow adequate defecation, and to harbor intestinal microbiota, for which their nutritional role is as important as it is unknown. This article will describe the causes and consequences of malnutrition in patients with inflammatory bowel diseases, the importance of screening and replacement of micronutrient deficits, and the main indications for enteral and parenteral nutrition in these patients. We will also discuss the causes of short bowel syndrome, a complex entity due to anatomical or functional loss of part of the small bowel, which can cause insufficient absorption of liquid, electrolytes, and nutrients and lead to complex management. Finally, we will review the causes, consequences, and management of malnutrition in patients with malignant and benign digestive tumors, including neuroendocrine tumors (present not only in the intestine but also in the pancreas).

Short bowel syndrome: treatment options

Introduction Short bowel syndrome (SBS) refers to the malabsorptive state that occurs following extensive intestinal resection and is associated with several complications.

Methods The research for this review was conducted in the Pubmed database. Relevant scientific articles dated between 1991 and 2015 and written in Portuguese, Spanish or English were selected.

Results Several therapies, including nutritional support, pharmacological options and surgical procedures have been used in these patients.

Conclusions Over the last decades new surgical and pharmacological approaches emerged, increasing survival and quality of life (QoL) in patients with SBS. All SBS patients ought to have an individualized and multidisciplinary care that promotes intestinal rehabilitation.

Evidence-based clinical practice guidelines for inflammatory bowel disease 2020

Inflammatory bowel disease (IBD) is a general term for chronic or remitting/relapsing inflammatory diseases of the intestinal tract and generally refers to ulcerative colitis (UC) and Crohn's disease (CD). Since 1950, the number of patients with IBD in Japan has been increasing. The etiology of IBD remains unclear; however, recent research data indicate that the pathophysiology of IBD involves abnormalities in disease susceptibility genes, environmental factors and intestinal bacteria. The elucidation of the mechanism of IBD has facilitated therapeutic development. UC and CD display heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management depends on the understanding and tailoring of evidence-based interventions by physicians. In 2020, seventeen IBD experts of the Japanese Society of Gastroenterology revised the previous guidelines for IBD management published in 2016. This English version was produced and modified based on the existing updated guidelines in Japanese. The Clinical Questions (CQs) of the previous guidelines were completely revised and categorized as follows: Background Questions (BQs), CQs, and Future Research Questions (FRQs). The guideline was composed of a total of 69 questions: 39 BQs, 15 CQs, and 15 FRQs. The overall quality of the evidence for each CQ was determined by assessing it with reference to the Grading of Recommendations Assessment, Development and Evaluation approach, and the strength of the recommendation was determined by the Delphi consensus process. Comprehensive up-to-date guidance for on-site physicians is provided regarding indications for proceeding with the diagnosis and treatment.

Effect of an Evidence-Based Nutrition Care Pathway for Cancer Patients Undergoing Gastrointestinal and Pelvic Surgery

Malnutrition in gastrointestinal surgery is associated with poorer post-operative outcomes which may be mitigated by delivery of evidence-based nutrition care. This study reports on the development, implementation and evaluation of an evidence-based nutrition care pathway for lower gastrointestinal and pelvic cancer patients. A retrospective cohort study of 40 surgical lower gastrointestinal and pelvic cancer patients pre- and post-implementation of the pathway was conducted. Outcomes assessed were, care pathway adherence, weight change, time to post-operative commencement of nutrition, and post-operative length of stay. Post-implementation of the pathway there were significant improvements in the proportion of patients who received dietetic assessment and education pre-surgery (0% vs 55%, P < .001) at regular intervals during admission (35% vs. 90%, P < .001) and post-discharge (22.5% vs. 81.8%, P < .001). Mean weight change between admission and discharge reduced post-implementation (-3.5%, SD 4.7 vs, -5.6%, SD 4.7; P = 0.08). Post-operative length of stay remained similar (16 day, IQR 11-34.7 vs. 17.5 day, IQR 11.2-25; P = 0.71). Post-implementation a greater proportion of patients commenced oral or enteral nutrition within 24 h, post-operatively (75% vs. 57.5%, P = 0.1). The nutrition care pathway was an effective method for delivering evidence-based nutrition care, resulting in clinically but not statistically significant improvements in outcomes.

Preoperative enteral nutrition in adults with complicated Crohn's disease: Effect on disease outcomes and gut microbiota

OBJECTIVES

The use of exclusive enteral nutrition (EEN) in patients with Crohn's disease (CD) before surgical resection can reduce disease activity and improve nutritional status. The mechanism of EEN action is unclear, but it might involve modulation of the intestinal microbiota. The aim of this study was to evaluate the effects (namely changes in gut microbiota) of preoperative EEN in adults with complicated CD referred to surgery.

METHODS

This was a prospective study of adult patients with CD referred to surgery. Patients with body mass index <18.5 kg/m², weight loss >10 %, serum albumin <3 g/dL, or a combination of some or all three, received EEN for ≥2 wk. The effects of EEN on clinical (Harvey-Bradshaw Index [HBI]) and laboratory markers (C-reactive protein [CRP], serum albumin, and fecal calprotectin) and fecal microbiota were analyzed after EEN (before surgery) and 6 mo later. We used 16 S rRNA gene sequencing to determine changes in the fecal microbiota.

RESULTS

Fifteen patients were included, of whom 60% were men with a mean age of 45.4 ± 19.1 y. Of those, 10 received EEN. The median duration of preoperative EEN was 41.5 d (15-70 d). During EEN, there was a significant reduction in mean HBI (8.7 ± 1.9 versus 4.1 ± 2.4; P = 0.001) and CRP (11.7 ± 10.3 versus 0.8 ± 0.8 mg/dL; P = 0.008) and an increase in serum albumin (3.1 ± 0.6 versus 4 ± 0.6 g/dL; P = 0.022). Two patients did not require surgery after EEN. The overall microbial composition changed after EEN (Permutational analysis of variance test, P = 0.046) and there was a significant reduction in α diversity (8 ± 2.3 versus 5.2 ± 1.5; P = 0.023). EEN significantly changed the relative abundance of 11 taxonomic operational units (OTUs). At the family level, we found this was mainly due to the decrease in the Enterobacteriaceae family (7 OTUs). Six months after surgery, α diversity was not different from that before or after EEN; at this time point 6 OTUs were significantly different, mainly due to the decrease of Clostridiales order (3 OTUs). The incidence of postoperative complications and hospital length of stay were similar in EEN and immediate surgery groups, as well as clinical and endoscopic recurrence rates 6 mo after surgery.

CONCLUSIONS

Preoperative EEN improved disease activity and nutritional status in patients with CD referred to surgery. Despite being malnourished, patients given EEN did not have increased postoperative complications compared with well-nourished patients. During EEN, overall microbiota composition changed and α diversity decreased. EEN did not influence postoperative recurrence and gut microbiota 6 mo after surgery.

Reduction in Healthcare Utilization With Transition to Peptide-Based Diets in Intolerant Home Enteral Nutrition Patients

BACKGROUND

Since the introduction of percutaneous endoscopic gastrostomy in the 1980s, the prevalence of home enteral nutrition (HEN) support has increased significantly. Despite these increases, many patients are unable to tolerate standard polymeric formulas (SPFs), resulting in significant healthcare resource utilization. Peptide-based diets (PBDs) have emerged as a viable option in SPF-intolerant patients; however, data in the HEN population are lacking.

METHODS

Retrospective review of our prospectively maintained HEN database was conducted to assess tolerance, efficacy, and impact on healthcare utilization in patients on PBDs.

RESULTS

From January 1, 2016, to May 1, 2018, 95 patients were placed on PBDs, with 53 patients being started directly and 42 patients being transitioned from SPFs. In patients transitioned to PBDs, symptoms of nausea and vomiting, diarrhea, abdominal pain, and distention improved significantly. Healthcare utilization also declined significantly, including mean number of phone calls (1.8 ± 1.6 to 1.1 ± 0.9, P = 0.006), mean number of emergency room visits (0.3 ± 0.6 to 0.09 ± 0.3, P = 0.015), and mean number of provider visits (1.3 ± 1.3 to 0.3 ± 0.5, P < 0.0001).

CONCLUSIONS

Overall, PBDs were well tolerated and resulted in significant improvements in symptoms of gastrointestinal distress and healthcare utilization in patients intolerant to SPFs.

Inflammatory bowel disease position statement of the Italian Society of Colorectal Surgery (SICCR): ulcerative colitis

The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a Position Statement of Italian colorectal surgeons to address the surgical aspects of ulcerative colitis management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the surgical treatment of ulcerative colitis. The committee was able to identify some points of major disagreement and suggested strategies to improve the quality of available data and acceptance of guidelines.

Exclusive enteral nutrition for induction of remission in anti-tumor necrosis factor refractory adult Crohn's disease: the Indian experience

Background/Aims

Exclusive enteral nutrition (EEN) is recommended for induction of remission in pediatric Crohn’s disease (CD). However, it is not currently recommended for inducing remission in adults. This report describes the use of 12-week EEN for induction of remission in anti-tumor necrosis factor (anti-TNF) refractory adult CD.

Methods

This is a retrospective analysis of adults with moderate to severe active (Crohn’s Disease Activity Index [CDAI] >220) anti-TNF refractory CD, who received EEN for 12 weeks between April 2018 and March 2019 at Dayanand Medical College and Hospital, Ludhiana, India. Primary outcomes included achievement of clinical remission and fistula healing at 12 weeks. Improvement in inflammatory markers and nutritional status were the secondary end points.

Results

Out of 23 patients who received anti-TNF agents, 7 (30.4%) were refractory and were offered EEN as a salvage therapy. Six patients (66.7% females, mean age 25.6±6.5 years) consented. Four patients (66.6%) achieved clinical remission (CDAI <150). Mean CDAI of patients decreased significantly after 12 weeks of EEN (388.8±74.8 vs. 160.0±25.2, P<0.001). Perianal fistulas showed clinical response (drainage decreased by >50%), though none achieved remission. Entero-enteric fistulae showed complete healing. Mean body mass index improved from 15.6±3.1 to 18.9±1.9 kg/m² at week 12 (P=0.003). Hemoglobin and serum albumin also improved from 8.2±1.1 g/dL and 2.8±0.3 g/dL at baseline to 12.6±0.6 g/dL and 3.6±0.5 g/dL post-EEN respectively (P<0.001 and P=0.006 respectively).

Conclusions

EEN appears to be an effective and well tolerated therapy for induction of remission in anti-TNF refractory adult CD. More data from prospective trials with larger number of patients is required.

ESPEN practical guideline: Clinical Nutrition in inflammatory bowel disease

The present guideline is the first of a new series of "practical guidelines" based on more detailed scientific guidelines produced by ESPEN during the last few years. The guidelines have been shortened and now include flow charts that connect the individual recommendations to logical care pathways and allow rapid navigation through the guideline. The purpose of the present practical guideline is to provide an easy-to-use tool to guide nutritional support and primary nutritional therapy in inflammatory bowel disease (IBD). The guideline is aimed at professionals working in clinical practice, either in hospitals or in outpatient medicine, and treating patients with IBD. In 40 recommendations, general aspects of care in patients with IBD, and specific aspects during active disease and in remission are addressed. All recommendations are equipped with evidence grades, consensus rates, short commentaries and links to cited literature.

Efficacy of enteral nutrition in patients with Crohn's disease on maintenance anti-TNF-alpha antibody therapy: a meta-analysis

Enteral nutrition (EN) is effective in Crohn's disease (CD) patients and has been shown to have an inhibitory effect on loss of response to anti-tumor necrosis factor (TNF)-alpha antibody therapy; however, the current level of evidence is not sufficient. The objective of this meta-analysis was to determine whether EN in combination anti-TNF-alpha antibody therapy is useful in maintaining remission. PubMed was used to identify all relevant studies. A total of nine articles were identified including one randomized control trial, two prospective cohort studies, and six retrospective cohort studies. We performed a meta-analysis on all these articles to assess the remission maintenance effect of EN (n = 857). The remission or response maintenance effect in the EN group was 203/288 (70.5%), which was higher than 306/569 (53.8%) in the non-EN group. The odds ratio for long-term remission or response using fixed effects model and random effects model were 2.23 (95% CI 1.60-3.10) and 2.19 (95% CI 1.49-3.22), respectively. The usefulness of EN was unclear in two prospective studies that were conducted immediately after remission induction with anti-TNF-alpha antibody therapy was detected. Differences in the definition of relapse and the observation period among articles were considered to be limitations. This analysis suggests that EN is effective for maintaining remission in patients already in remission or response as a result of anti-TNF-alpha antibody maintenance therapy.

Malnutrition impairs mitochondrial function and leukocyte activation

BACKGROUND

The aim of this study was to evaluate markers of inflammation, oxidative stress and endothelial function in a disease-related malnutrition (DRM) outpatient population.

METHODS

For this cross-sectional study, a total of 83 subjects were included and clustered in 3 groups: 34 with normonutrition (NN), 21 with DRM without inflammation (DRM-I) and 28 with DRM and inflammation (DRM + I). Nutritional diagnosis was conducted for all subjects according to ASPEN. Biochemical parameters, proinflammatory cytokines, reactive oxygen species production, glutathione, mitochondrial membrane potential, oxygen consumption, adhesion molecules and leukocyte-endothelium interactions were evaluated.

RESULTS

DRM + I patients showed lower albumin, prealbumin, transferrin, and retinol-binding protein levels with respect to the NN group (p < 0.05), differences that were less noticeable in the DRM-I group. DRM + I was associated with a significant increase in hsCRP and IL6 vs the NN and DRM-I groups, and TNFα was increased in both DRM vs NN. DRM was characterised by increased oxidative stress, which was marked by a significant increase in ROS levels and a decrease in mitochondrial membrane potential in the DRM + I group. An evident reduction in mitochondrial oxygen consumption and glutathione concentration was observed in both DRM groups, and was accompanied by increased leukocyte adhesion and adhesion molecules and decreased rolling velocity in the DRM + I group. Furthermore, percentage of weight loss was negatively correlated with albumin, prealbumin, transferrin, O₂ consumption, glutathione and leukocyte rolling velocity, and positively correlated with hsCRP, IL6, TNFα, ROS, leukocyte adhesion, and VCAM-1.

CONCLUSIONS

Our results show that DRM is associated with oxidative stress and an inflammatory state, with a deterioration of endothelial dysfunction in the DRM + I population.

Effect of Oral Nutrition Supplements and TGF-β2 on Nutrition and Inflammatory Patterns in Patients With Active Crohn's Disease

BACKGROUND

Crohn's disease (CD) is often associated with nutrition disorders. Many nutrition therapeutic alternatives have been studied. Nevertheless, the actual role of nutrition therapy is still controversial. The objective of this study was to assess the effects of nutrition supplementation with and without transforming growth factor-beta 2 (TGF-β2) on inflammatory, endoscopic, histopathologic, and nutrition parameters in active CD.

MATERIALS AND METHODS

Thirty-eight patients were allocated into 3 groups: group 1 (patients who received only nutrition orientation), group 2 (nutrition orientation and a normoproteic, normocaloric nutrition supplement), and group 3 (nutrition orientation and the nutritional supplement with TGF-β2). Clinical and nutrition evaluation, C-reactive protein (CRP) levels, and assessment of endoscopic and histologic parameters in the intestinal mucosa were performed before and after nutrition intervention.

RESULTS

The mean follow-up period was 3 months. In the beginning of the study, groups were homogeneous regarding age, gender, CD behavior and localization, and medication in use. In the end of the study, the Clinical Disease Activity Index score was reduced in groups 2 and 3; in group 3, a reduction in CRP levels and an improvement in histologic findings were observed. Among patients who received nutritional supplement, some anthropometric patterns were improved.

CONCLUSION

The results of the study indicate that nutritional supplementation improved nutrition and inflammatory patterns in patients with active CD. However, only patients receiving TGF-β2-enriched formula showed improvement in histologic parameters and significant reduction in CRP levels.

Enteral Nutrition in Adult Crohn's Disease: Toward a Paradigm Shift

Medical and surgical treatments for Crohn's disease are associated with toxic effects. Medical therapy aims for mucosal healing and is achievable with biologics, immunosuppressive therapy, and specialised enteral nutrition, but not with corticosteroids. Sustained remission remains a therapeutic challenge. Enteral nutrition, containing macro- and micro-nutrients, is nutritionally complete, and is provided in powder or liquid form. Enteral nutrition is a low-risk and minimally invasive therapy. It is well-established and recommended as first line induction therapy in paediatric Crohn's disease with remission rates of up to 80%. Other than in Japan, enteral nutrition is not routinely used in the adult population among Western countries, mainly due to unpalatable formulations which lead to poor compliance. This study aims to offer a comprehensive review of available enteral nutrition formulations and the literature supporting the use and mechanisms of action of enteral nutrition in adult Crohn's disease patients, in order to support clinicians in real world decision-making when offering/accepting treatment. The mechanisms of actions of enteral feed, including their impact on the gut microbiome, were explored. Barriers to the use of enteral nutrition, such as compliance and the route of administration, were considered. All available enteral preparations have been comprehensively described as a practical guide for clinical use. Likewise, guidelines are reported and discussed.

The occlusion balloon reduction technique for de novo placement and salvage of malpositioned enteric tubes

PURPOSE

Nasoenteric, gastrojejunostomy, and jejunostomy tubes are methods of enteral nutrition in patients with functioning gastrointestinal tracts who cannot maintain adequate oral intake. Current placements; however, may be complicated by redundant wire and catheter loops within the stomach preventing operators from optimal feeding tube placement and predisposing patients to feeding tube prolapse. This report describes the occlusion balloon reduction technique for salvage of malpositioned tubes and placement of new enteric tubes in the setting of redundant loops.

MATERIALS AND METHODS

Five patients underwent the occlusion balloon reduction technique for jejunostomy (n = 3), gastrojejunostomy (n = 1), or nasojejunal tube placement (n = 1). All patients (n = 5) had redundant wires coiled within the stomach. In all patients (n = 5), a 9-French × 32 mm × 120 cm Coda balloon was inserted over the wire and passed into the small bowel. The balloon was inflated after which reduction of redundancy in the upper gastrointestinal tract was performed. Feeding tubes were then placed with tips in the distal jejunum. Technical success of the occlusion balloon reduction technique, successful placement of enteric tube, complications, and follow-up were recorded.

RESULTS

The occlusion balloon reduction was technically successful in all patients (n = 5). Feeding tube placement was successful in all patients (n = 5). No minor or major complication occurred. Mean follow-up was 56 days.

CONCLUSION

The occlusion balloon reduction technique provides a method for reduction of redundant wire and catheter loops within the stomach during enteric tube placement or repositioning.

A Diet Low in Red and Processed Meat Does Not Reduce Rate of Crohn's Disease Flares

BACKGROUND & AIMS

Diet may be an important factor in the progression of Crohn's disease (CD). We performed a randomized controlled trial to determine whether reduced consumption of red and processed meats decreases the risk of symptomatic relapse of CD, analyzing results from the Food and Crohn's Disease Exacerbation Study (FACES) trial.

METHODS

Adults with CD were recruited into the FACES trial from IBD Partners, an Internet-based cohort of patients with inflammatory bowel disease, from November 2013 through June 2015. Individuals who were in remission (CD activity index [sCDAI] scores of ≤150), had completed a biannual survey, and reported consumption of red meat at least once weekly were randomly assigned to groups that consumed a minimum of 2 servings/week of red or processed meat (high meat, n = 118) or not more than 1 serving per month (low meat, n = 96) for 49 weeks. The primary outcome was relapse of CD, defined as increase in sCDAI score by ≥70 points and to >150 or a need for CD surgery or new CD medication. A secondary outcome, moderate or severe relapse, was based on an increase in sCDAI to >219.

RESULTS

During the trial, the high-meat groups reported consumption of 2 or more servings of red or processed meat during 98.5% of observed weeks compared with 18.8% of weeks for the low-meat group. Any and moderate to severe relapse occurred in 62% of participants in the high-meat group and 42% of participants in the low-meat group. There were no significant differences in time to any (P = .61) or moderate/severe (P = .50) relapse.

CONCLUSIONS

In an analysis of data from the FACES trial, we found that among patients with CD in remission, level of red and processed meat consumption was not associated with time to symptomatic relapse. ClinicalTrials.gov, Number: NCT0192673.

Predicting the Risk of Weight Loss After Esophageal Cancer Surgery

Background

Malnutrition after esophageal cancer surgery is associated with reduced health-related qualify of life. Therefore, a prediction model identifying patients at risk for severe weight loss after surgery was developed.

Methods

Data from a Swedish population-based cohort study, including 616 patients undergoing esophageal cancer surgery in 2001–2005, was used. Candidate predictors included risk factors available before and immediately after surgery. Severe weight loss was defined as ≥ 15% loss of body weight between the time of surgery and 6 months postoperatively. The prediction model was developed using multivariable models. The accuracy of the model was measured by the area under the receiver operating characteristics curve (AUC) with bootstrap validation. The model was externally validated in a hospital-based cohort of 91 surgically treated esophageal cancer patients in the United Kingdom in 2011–2016. Each predictor in the final model was assigned a corresponding risk score. The sum of risk scores was equivalent to an estimated probability for severe weight loss.

Results

Among the 351 patients with 6 months follow-up data, 125 (36%) suffered from severe postoperative weight loss. The final prediction model included body mass index at diagnosis, preoperative weight loss, and neoadjuvant therapy. The AUC for the model was 0.78 (95% CI 0.74–0.83). In the validation cohort, the AUC was 0.76. A clinical risk assessment guide was derived from the prediction model.

Conclusions

This prediction model can preoperatively identify individuals with high risk of severe weight loss after esophageal cancer surgery. Intensive nutritional interventions for these patients are recommended.

ACG Clinical Guideline: Ulcerative Colitis in Adults

Ulcerative colitis (UC) is an idiopathic inflammatory disorder. These guidelines indicate the preferred approach to the management of adults with UC and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) process. In instances where the evidence was not appropriate for GRADE, but there was consensus of significant clinical merit, "key concept" statements were developed using expert consensus. These guidelines are meant to be broadly applicable and should be viewed as the preferred, but not only, approach to clinical scenarios.

Blood concentrations and renal clearance of water-soluble vitamins in outpatients with ulcerative colitis

Few studies have investigated the association between dietary intake and blood concentrations of water-soluble vitamins in patients with ulcerative colitis (UC). In the present study, vitamin concentrations were measured in the blood and urinary excretion of 23 outpatients with UC and compared against a control group of 20 healthy participants. A weighed food record procedure was used to ensure controlled macronutrient and vitamin intakes of the UC cohort. Individuals in the control group were given a semi-purified diet for 8 days prior to assessment. Multiple linear regression analysis was used to identify important differences in vitamin concentrations, independent of sex, age and other confounding variables. The blood concentrations of vitamins B2, C, niacin and folate were markedly lower in the patients with UC than those in the control group, and the renal clearance of vitamins B1, B6, B12 and folate was notably higher in the UC cohort. It was concluded that vitamins B2, C, niacin and folate were at significantly lower concentrations in patients with UC following adjustment for coexisting factors. The lower levels of niacin may be partially due to impaired reabsorption. Chronic inflammation, common in patients with UC, with may contribute to the lower levels of other vitamins by rendering amino acid and carbohydrate metabolism into a hypermetabolic state. As the role of vitamins in metabolic activity is constant and pervasive, nutritional management including the application of water-soluble vitamins appears important for patients suffering from UC.

Enteral Nutrition Support Does Not Improve PNI in Radiotherapy Patients with Locally Advanced Esophageal Cancer

OBJECTIVE

The assessment of prognostic nutritional index (PNI) before and during radiotherapy is an important parameter for the prognosis in patients with cancer. In this study, enteral tube feeding (ETF) was used during radiotherapy in patients with EC. Dynamic changes of various nutritional indicators (including PNI) were monitored.

METHODS

Patients with EC who underwent radiotherapy between June 2016 and July 2017 were enrolled. ETF was performing with the energy of 25 kcal × kg/d. Nutritional status were evaluated. Least significant difference (LSD) was used for multiple comparisons between groups.

RESULTS

A total of 148 patients were admitted, including 51 patients fed via ETF. For patients who were not scheduled to nutritional support, significant difference were observed in albumin (ALB) (P < 0.001), prealbimnin (PA) (P = 0.05) and PNI (P < 0.001) compared to levels before radiotherapy. In the patients fed via enteral tube, no significant difference were found in weight, BMI, ALB, retinol binding protein (RBP) and PA before and after radiotherapy, while PNI significantly decreased (P < 0.001).

CONCLUSION

After preforming ETF with the energy of 25 kcal × kg/d in patients with EC during radiotherapy, PNI, the key nutritional index reflecting prognosis, significantly decreased.
