Abstract
Bariatric surgery (BS) may be effective for chronic kidney disease (CKD) patients by reducing microalbuminuria and proteinuria, and by facilitating their meeting inclusion criteria for kidney transplantation. However, nutritional management for this population is complex and specific guidelines are scarce. A literature search was performed to create dietetic practice for these patients based on the most recent evidence. For the purposes of nutritional recommendations, we divided the patients into 2 subgroups: 1) patients with CKD and dialysis, and 2) patients after kidney transplantation. Before surgery, nutritional care includes nutritional status evaluation and adjusting doses of supplements to treat deficiencies and daily nutrient intake according to the dietary restrictions derived from kidney disease, including quantities of fluids, protein, phosphorus, potassium, and vitamins. After BS, these patients are at major risk for lean body mass loss, malnutrition and dehydration because of fluid restriction and diuretics. Postoperative nutritional recommendations should be carefully tailored according to CKD nutritional limitations and include specific considerations regarding protein, fluids, and supplementation, in particular calcium, vitamin A, and vitamin D. Nutritional management of CKD and kidney transplant patients undergoing BS is challenging and future studies are required to establish uniform high-level evidence-based guidelines.

Growth failure in Crohn's disease children: may the first treatment have a role?
Capriati, T, Bizzarri, C, Dilillo, A, Nobili, V, Oliva, S, Diamanti, A
Expert review of clinical immunology. 2019;(1):97-104
Abstract
Introduction: Growth failure in children is a frequent feature of childhood-onset Crohn's disease (CD), and stunting can persist into adulthood. Growth is an important outcome by which to judge the effectiveness of therapies in children; currently available studies in CD children have focused on the short-term impact of treatments on growth, and there are limited data regarding the long-term effects of treatments upon growth. Areas covered: We designed the present article to review whether the first treatment performed in newly diagnosed CD children may have a role on the future growth course. We conducted a systematic literature search to identify relevant studies published on the PubMed database from January 2002 up to now. We found only six surveys that documented mid-term growth course in newly diagnosed CD patients. Expert commentary: In the last years there have been relevant advances in the clinical management of CD children; however, there is a lack of knowledge about the best strategy to reverse growth failure. Children treated with enteral nutrition have appropriate height and weight gain but do not reverse the growth course. Further surveys are required to better explore not only clinical outcomes but also long-term growth course following each therapeutic strategy.

Abstract
PURPOSE Variations of clinical nutrition may affect outcome of critically ill patients. Here we present the short version of the updated consenus-based guideline (S2k classification) "Clinical nutrition in critical care medicine" of the German Society for Nutritional Medicine (DGEM) in cooperation with 7 other national societies. The target population of the guideline was defined as critically ill adult patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g. mechanical ventilation) to maintain organ function. METHODS The former guidelines of the German Society for Nutritional Medicine (DGEM) were updated according to the current instructions of the Association of the Scientific Medical Societies in Germany (AWMF) valid for a S2k-guideline. We considered and commented the evidence from randomized-controlled trials, meta-analyses and observational studies with adequate sample size and high methodological quality (until May 2018) as well as from currently valid guidelines of international societies. The liability of each recommendation was indicated using linguistic terms. Each recommendation was finally validated and consented by a Delphi process. RESULTS The short version presents a summary of all 69 consented recommendations for essential, practice-relevant elements of clinical nutrition in the target population. A specific focus is the adjustment of nutrition according to the phases of critical illness, and to the individual tolerance to exogenous substrates. Among others, recommendations include the assessment of nutritional status, the indication for clinical nutrition, the timing, route, magnitude and composition of nutrition (macro- and micronutrients) as well as distinctive aspects of nutrition therapy in obese critically ill patients and those with extracorporeal support devices. CONCLUSION The current short version of the guideline provides a concise summary of the updated recommendations for enteral and parenteral nutrition of adult critically ill patients who suffer from at least one acute organ dysfunction requiring pharmacological and/or mechanical support. The validity of the guideline is approximately fixed at five years (2018 - 2023).

Management of Exocrine Pancreatic Insufficiency in Children.
Sankararaman, S, Schindler, T, Sferra, TJ
Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition. 2019;:S27-S42
Abstract
The diagnosis of exocrine pancreatic insufficiency (EPI) can be difficult, as symptoms may be nonspecific. A delayed diagnosis of EPI can negatively impact health through poor weight gain, impaired growth, and malabsorption of nutrients. Because of active growth and development, children are more vulnerable to the consequences of untreated EPI. Pancreatic enzyme replacement therapy is the cornerstone of management and offers both symptomatic relief and improvement in clinical outcomes. Additionally, a high-energy diet with unrestricted fat and supplementation with fat-soluble vitamins is often required to optimize growth and prevent nutrition deficiencies. Cystic fibrosis (CF) is the most common condition in children that causes EPI, and improvement in nutrition management is associated with improved pulmonary function and increased survival. Currently, the management of other conditions leading to EPI in children is not well studied, and inferences from the CF literature are often necessary in caring for these patients.

Dietary Patterns and Cardiometabolic Outcomes in Diabetes: A Summary of Systematic Reviews and Meta-Analyses.
Kahleova, H, Salas-Salvadó, J, Rahelić, D, Kendall, CW, Rembert, E, Sievenpiper, JL
Nutrients. 2019;(9)
Abstract
The Diabetes and Nutrition Study Group (DNSG) of the European Association for the Study of Diabetes (EASD) conducted a review of existing systematic reviews and meta-analyses to explain the relationship between different dietary patterns and patient-important cardiometabolic outcomes. To update the clinical practice guidelines for nutrition therapy in the prevention and management of diabetes, we summarize the evidence from these evidence syntheses for the Mediterranean, Dietary Approaches to Stop Hypertension (DASH), Portfolio, Nordic, liquid meal replacement, and vegetarian dietary patterns. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence. We summarized the evidence for disease incidence outcomes and risk factor outcomes using risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs), respectively. The Mediterranean diet showed a cardiovascular disease (CVD) incidence (RR: 0.62; 95%CI, 0.50, 0.78), and non-significant CVD mortality (RR: 0.67; 95%CI, 0.45, 1.00) benefit. The DASH dietary pattern improved cardiometabolic risk factors (P < 0.05) and was associated with the decreased incidence of CVD (RR, 0.80; 95%CI, 0.76, 0.85). Vegetarian dietary patterns were associated with improved cardiometabolic risk factors (P < 0.05) and the reduced incidence (0.72; 95%CI: 0.61, 0.85) and mortality (RR, 0.78; 95%CI, 0.69, 0.88) of coronary heart disease. The Portfolio dietary pattern improved cardiometabolic risk factors and reduced estimated 10-year coronary heart disease (CHD) risk by 13% (-1.34% (95%CI, -2.19 to -0.49)). The Nordic dietary pattern was correlated with decreased CVD (0.93 (95%CI, 0.88, 0.99)) and stroke incidence (0.87 (95%CI, 0.77, 0.97)) and, along with liquid meal replacements, improved cardiometabolic risk factors (P < 0.05). The evidence was assessed as low to moderate certainty for most dietary patterns and outcome pairs. Current evidence suggests that the Mediterranean, DASH, Portfolio, Nordic, liquid meal replacement and vegetarian dietary patterns have cardiometabolic advantages in populations inclusive of diabetes.

Combining optimal nutrition and exercise in a multimodal approach for patients with active cancer and risk for losing weight: Rationale and practical approach.
Solheim, TS, Vagnildhaug, OM, Laird, BJ, Balstad, TR
Nutrition (Burbank, Los Angeles County, Calif.). 2019;:110541
Abstract
Weight loss and functional decline is a common and detrimental consequence of cancer. The interventions that are offered to patients with weight loss and functional decline often seem haphazard and varying from center to center. The lack of stringent management is probably based both on lack of knowledge of existing treatment guidelines and the current weak level of evidence of clinical effects of different nutritional and exercise interventions. Some studies evaluated multimodal interventions with various treatment combinations, including nutrition and exercise, that report clinically significant effects on cachexia outcomes. As of today, however, there is a paucity of large randomized controlled trials that incorporate both a fully structured exercise program and a well-described nutritional intervention. Studies investigating combinations of several interventions in patients with active cancer and risk for losing weight are too few and too heterogeneous to enable firm conclusions about effect, optimal dose, or timing of interventions. However, data presented in this review suggest an overall benefit, especially if interventions are started before weight loss and loss of function become too severe. Thus, the aim of this review was to examine the evidence for combined treatments targeting weight loss in cancer patients.

Performance and altitude: Ways that nutrition can help.
Caris, AV, Santos, RVT
Nutrition (Burbank, Los Angeles County, Calif.). 2019;:35-40
Abstract
High altitudes are a challenge for human physiology and for sports enthusiasts. Several reasons lead to deterioration in performance at high altitudes. Hypoxia owing to high altitude causes a breakdown of homeostasis with imbalance in several physiological systems, including the immune system. The reduction in mucosal immunity and inflammation and the predominance of the humoral immune response causes a condition of immunosuppression and an increased likelihood of infection. In addition, it is known that worsening of the immune response is associated with reduced performance. On the other hand, immunonutrition plays an important role in modulating the effects of physical exercise on the immune system. However, to our knowledge, few studies have evaluated the effect of nutrition on the immune system after exercise in hypoxia. Although the association between exercise and hypoxia has been shown to be more severe for the body owing to the sum of stressful agents, supplementation with carbohydrates and glutamine seems to play a relevant role in mitigating immunosuppressive effects. These findings, although limited by the fact that they are the result of very few studies, shed light on a relevant theme for sports physiology and nutrition and suggest that both supplements may be useful for athletes, visitors, and workers in high-altitude regions. The aim of this review was to discuss the effects of high-altitude hypoxia on the human body from the point of view of exercise immunology because it is known that transient immunosuppression after strenuous exercise and competition should be followed by reduction in training overload and worse performance.

Controversy in Nutrition Recommendations for Short Bowel Syndrome: How Type of SBS Impacts Response.
Austin, K, Bonnes, S, Daniel, H
Current gastroenterology reports. 2019;(12):64
Abstract
PURPOSE OF REVIEW This review examines the current recommendations for dietary management of patients living with short bowel syndrome (SBS) and outlines the need for future research to provide optimal care for this unique group of patients. RECENT FINDINGS Providers caring for patients with SBS lack sufficient data to help guide recommendations regarding diet. The majority of studies are conducted at a single medical institution on a small number of anatomically diverse patients. Multi-center studies would allow for inclusion of a larger number of patients and may lead to more individualized dietary recommendations. Patients with short bowel syndrome should be evaluated on an individual basis by a multidisciplinary team including physicians, dieticians, pharmacists, and nurses specializing in the care of these complex patients. Tailoring both medical and nutritional therapy will help realize the overarching goal for these patients of maintaining adequate nutrition with diet and medications, and achieving independence from parenteral support.

Factors That Worsen Disease Severity in Acute Pancreatitis: Implications for More Innovative Nutrition Therapy.
McClave, SA
Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition. 2019;:S43-S48
Abstract
The pathophysiologic process of severe acute pancreatitis involves a vicious cycle of inflammation and increasing oxidative stress. Secretory defects trap activated pancreatic enzymes within the gland leading to autodigestion while circulatory abnormalities add the insult of ischemia/reperfusion injury. What may have the greatest impact in amplifying the systemic inflammatory response, though, is intestinal failure with breakdown of gut barrier defenses, subversion of submucosal immune responses, and emergence of a virulent pathobiome. Understanding the intricacies of these changes has broad-reaching implications for nutrition therapy, which should no longer be limited to the provision of early enteral feeding alone. Emerging strategies should attempt to maintain commensalism, bind potential pathogens, refaunate the microbiome, actively turn off inflammation, reset cross-talk signaling with epithelial receptors, and deliver nutrients further down the gastrointestinal tract to the level of greatest microbial burden. Innovative nutrition therapy for the patient with severe acute pancreatitis should be designed to address and include all of these strategies in order to shift the course of clinical outcome toward a pattern of recovery and homeostasis.

Abstract
Cancer-related fatigue (CRF) is a debilitating syndrome that persists for many cancer survivors for years after treatment. Symptoms include early and persistent fatigue, functional decline, depression, and cognitive difficulties. Inflammation, assessed using pro-inflammatory biomarkers, is increased in cancer survivors with fatigue and treatments for fatigue are often aimed at reducing inflammation. Additionally, cancer and its treatment lead to nutritional complications, changes in body composition, and nutritional deficiencies that potentially weaken the cancer survivor and impact CRF. We conducted a qualitative review of clinical trials that assessed nutritional interventions for preventing and treating CRF. Further studies were examined that used nutritional interventions to address inflammation and fatigue, due to the dearth of nutrition research directly related to CRF. Dietary intake prior to, during, and after cancer treatment appears to affect fatigue levels. Increased protein intake may help preserve lean mass and body composition. Dietary patterns that reduce inflammation, such as the Mediterranean diet and other plant-based diets, appear tolerable to cancer survivors and may reduce fatigue. Supplementation with ginseng, ginger, or probiotics may improve cancer survivors' energy levels. Nutritional interventions, alone or in combination with other interventions should be considered as therapy for fatigue in cancer survivors.
