Dietetics After Spinal Cord Injury: Current Evidence and Future Perspectives.
Farkas, GJ, Sneij, A, Gater, DR
Topics in spinal cord injury rehabilitation. 2021;(1):100-108
Abstract
Following spinal cord injury (SCI), individuals are at high risk for obesity and several chronic cardiometabolic disorders due to a deterioration in body composition, hypometabolic rate, and endometabolic dysregulation. Countermeasures to the consequences of an SCI include adopting a healthy diet that provides adequate nutrition to maintain good body habitus and cardiometabolic health. A proper diet for individuals with SCI should distribute carbohydrates, protein, and fat to optimize a lower energy intake requirement and should stress foods with low caloric yet high nutrient density. The purpose of this article is to present available evidence on how nutritional status after SCI should advance future research to further develop SCI-specific guidelines for total energy intake, as it relates to percent carbohydrates, protein, fat, and all vitamins and minerals, that take into consideration the adaptations after SCI.

Craig, WJ, Mangels, AR, Fresán, U, Marsh, K, Miles, FL, Saunders, AV, Haddad, EH, Heskey, CE, Johnston, P, Larson-Meyer, E, et al
Nutrients. 2021;(11)
Abstract
Plant-based diets, defined here as including both vegan and lacto-ovo-vegetarian diets, are growing in popularity throughout the Western world for various reasons, including concerns for human health and the health of the planet. Plant-based diets are more environmentally sustainable than meat-based diets and have a reduced environmental impact, including producing lower levels of greenhouse gas emissions. Dietary guidelines are normally formulated to enhance the health of society, reduce the risk of chronic diseases, and prevent nutritional deficiencies. We reviewed the scientific data on plant-based diets to summarize their preventative and therapeutic role in cardiovascular disease, cancer, diabetes, obesity, and osteoporosis. Consuming plant-based diets is safe and effective for all stages of the life cycle, from pregnancy and lactation, to childhood, to old age. Plant-based diets, which are high in fiber and polyphenolics, are also associated with a diverse gut microbiota, producing metabolites that have anti-inflammatory functions that may help manage disease processes. Concerns about the adequate intake of a number of nutrients, including vitamin B12, calcium, vitamin D, iron, zinc, and omega-3 fats, are discussed. The use of fortified foods and/or supplements as well as appropriate food choices are outlined for each nutrient. Finally, guidelines are suggested for health professionals working with clients consuming plant-based diets.

Weight Management Interventions for Adults With Overweight or Obesity: An Evidence Analysis Center Scoping Review.
Cheng, FW, Garay, JL, Handu, D
Journal of the Academy of Nutrition and Dietetics. 2021;(9):1855-1865
Abstract
The objectives of this evidence scoping review were to identify and characterize studies investigating weight management interventions provided by a registered dietitian nutritionist or international equivalent (RDN) among adults with overweight or obesity. A medical librarian conducted an electronic literature search in 6 databases-MEDLINE (Ovid), Embase (Ovid), PyscINFO (Ovid), Cochrane CENTRAL (Ovid), Cochrane Database of Systematic Reviews (Ovid), and CINAHL (Ebsco). Except for narrative review, gray literature, and case study or report, all types of peer-reviewed articles published between January 2008 and April 26, 2019 were eligible. Two content advisors, who are experts in adult weight management, guided the process and reviewed the search plan and findings. The literature search resulted in 30,551 records with 16 additional records identified through other sources. A total of 29,756 records were excluded during the first round of screening due to duplication or irrelevancy. Of the 811 full-text articles that were screened, 139 met the criteria and were included. Approximately 51% and 43% of the studies were conducted in the community setting and in the United States or Canada, respectively. Over 97% of the studies were clinical or quasi-experimental trials. A total of 6 different intervention delivery modes were reported, which resulted in 22 combinations of the modes of delivery. RDNs delivered the weight management intervention (especially the nutrition component) in all studies, but some (61%) also involved an interdisciplinary team to deliver other components of the intervention. The average length of the intervention was about 10 months with a follow-up that ranged from 0 to 9 years. The commonly reported outcomes were anthropometrics, endocrine, and cardiovascular measures; dietary intake; and physical activity. Based on the scoping review, there were systematic reviews and evidence-based practice guidelines on weight management interventions but none of them met the a priori inclusion or exclusion criteria. Therefore, it would be beneficial to conduct a systematic review and develop an evidence-based practice guideline on adult weight management interventions provided by an RDN to guide practitioners and to evaluate their effects on health and nutrition-related outcomes.

Bakaloudi, DR, Chrysoula, L, Poulia, KA, Dounousi, E, Liakopoulos, V, Chourdakis, M
Nutrients. 2021;(2)
Abstract
Chronic kidney disease (CKD) is an important public health issue with increasing prevalence worldwide. Several clinical practice guidelines have been recently published regarding the nutritional management of CKD patients. The purpose of the present study is to evaluate the quality of the published guidelines and provide recommendation for future updates. PubMed, Scopus and Google Scholar were searched for relevant guidelines and 11 clinical practice guidelines were finally included. Guidelines developed by the American Society for Parenteral and Enteral nutrition (ASPEN), the Dietitians Association of Australia (DAA), the German Society for Nutritional Medicine (DGEM), the European Best Practice Guidelines (EBPG), the European Dialysis and Transplantation Nurses Association-European Renal Care Association (EDTNA-ERCA), the European Society for Clinical Nutrition and Metabolism (ESPEN), the Andalusian Group for Nutrition Reflection and Investigation (GARIN) group, the National Kidney foundation-Kidney Disease Outcomes Quality Initiative (KDOQI), the Italian Society of Nephrology-Association of Dieticians-Italian Association of Hemodialysis, Dialysis and Transplant (SIN-ANDID-ANED), and the Renal Association were assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool. Guidelines by KDOQI, ESPEN, and DAA were of moderate quality and the rest of them were low-quality guidelines. Our study demonstrates gaps related to the development of guidelines and therefore greater emphasis on methodological approaches is recommended. AGREE II tool can be useful to improve quality of guidelines.

Siopis, G, Wang, L, Colagiuri, S, Allman-Farinelli, M
Journal of human nutrition and dietetics : the official journal of the British Dietetic Association. 2021;(1):81-93
Abstract
BACKGROUND The management of diabetes costs in excess of $1.3 trillion per annum worldwide. Diet is central to the management of type 2 diabetes. It is not known whether dietetic intervention is cost effective. This scoping review aimed to map the existing literature concerning the cost effectiveness of medical nutrition therapy provided by dietitians for people with type 2 diabetes. METHODS Thirteen scientific databases, including MEDLINE, EMBASE and CINAHL, as well as multiple official websites, were searched to source peer-reviewed articles, reports, guidelines, dissertations and other grey literature published from 2008 to present. Eligible articles had to have assessed and reported the cost effectiveness of dietetic intervention for adults with type 2 diabetes in developed countries. Experimental, quasi-experimental, observational and qualitative studies were considered. RESULTS Of 2387 abstracts assessed for eligibility, four studies combining 22 765 adults with type 2 diabetes were included. Dietetic intervention was shown to be cost-effective in terms of diabetes-related healthcare costs and hospital charges, at the same time as also reducing the risk of cumulative days at work lost to less than half and the risk of disability 'sick' days at work to less than one-seventh. CONCLUSIONS The findings highlight the importance of advocacy for medical nutrition therapy for people with type 2 diabetes, with respect to alleviating the great global economic burden from this condition. Further studies are warranted to elucidate the factors that mediate and moderate cost effectiveness and to allow for the generalisation of the findings.

Clinical Implications of Malnutrition in the Management of Patients with Pancreatic Cancer: Introducing the Concept of the Nutritional Oncology Board.
Rovesti, G, Valoriani, F, Rimini, M, Bardasi, C, Ballarin, R, Di Benedetto, F, Menozzi, R, Dominici, M, Spallanzani, A
Nutrients. 2021;(10)
Abstract
Pancreatic cancer represents a very challenging disease, with an increasing incidence and an extremely poor prognosis. Peculiar features of this tumor entity are represented by pancreatic exocrine insufficiency and an early and intense nutritional imbalance, leading to the highly prevalent and multifactorial syndrome known as cancer cachexia. Recently, also the concept of sarcopenic obesity has emerged, making the concept of pancreatic cancer malnutrition even more multifaceted and complex. Overall, these nutritional derangements play a pivotal role in contributing to the dismal course of this malignancy. However, their relevance is often underrated and their assessment is rarely applied in clinical daily practice with relevant negative impact for patients' outcome in neoadjuvant, surgical, and metastatic settings. The proper detection and management of pancreatic cancer-related malnutrition syndromes are of primary importance and deserve a specific and multidisciplinary (clinical nutrition, oncology, etc.) approach to improve survival, but also the quality of life. In this context, the introduction of a "Nutritional Oncology Board" in routine daily practice, aimed at assessing an early systematic screening of patients and at implementing nutritional support from the time of disease diagnosis onward seems to be the right path to take.

Economic benefit of dietetic-nutritional treatment in the multidisciplinary primary care team.
Casas-Agustench, P, Megías-Rangil, I, Babio, N
Nutricion hospitalaria. 2020;(4):863-874
Abstract
Chronic diseases and aging are placing an ever increasing burden on healthcare services worldwide. Nutritional counselling is a priority for primary care because it has shown substantial cost savings. This review aims to evaluate the evidence of the cost-effectiveness of nutritional care in primary care provided by health professionals. A literature search was conducted using PubMed/MEDLINE between January 2000 and February 2019. The review included thirty-six randomized controlled trials (RCTs) and systematic reviews conducted in healthy people and people with obesity, type-2 diabetes mellitus, cardiovascular risk or malnutrition. All the RCTs and reviews showed that nutritional intervention led by dietitians-nutritionists in people with obesity or cardiovascular risk factors was cost-effective. Dietary interventions led by nurses were cost-effective in people who needed to lose weight but not in people at high cardiovascular risk. Some dietary changes led by a primary care team in people with diabetes were cost-effective. Incorporating dietitians-nutritionists into primary care settings, or increasing their presence, would give people access to the healthcare professionals who are best qualified to carry out nutritional treatment, and may be the most cost-effective intervention in terms of health expenditure. Notwithstanding the limitations described, this review suggests that incorporating dietitians-nutritionists into primary health care as part of the multidisciplinary team could be regarded as an investment in health. Even so, more research is required to confirm the conclusions.

Abstract
Decision making in nutrition is based on current available scientific evidence. However, we are currently living in a time of highly accessible information, and with the increase in accessibility has come a concomitant increase in misinformation and pseudoscience relating to nutrition. This presents a challenge to the nutrition research community, practitioners, and consumers, and highlights a need to critically examine the current evidence-based framework in nutrition, and identify strategies for future improvements. This narrative review outlines the current evidence-based framework and approaches to evidence-based practice in the nutrition field, focusing on policy and guideline development. Within the framework, systematic reviews are an important tool for evidence-based practice, underpinning translation guidelines and other implementation documents. Recommendations for consumption of nutrients, foods, and whole diets are required to guide consumers and practitioners; however, these resources must be updated regularly to remain timely and accurate. In turn, clinical practice guidelines guide practitioners in how to implement the evidence base for patients and clients, supporting practitioners to be positioned as a key conduit between scientific evidence and the public. In contrast, health claims may support marketing of food products, but require consideration of the strength and quality of the evidence to support health claims, with external oversight required to ensure claims are appropriate. Collecting, synthesizing, and translating the evidence base in nutrition remains an ongoing challenge, particularly in the current context of increased information availability. To address growing challenges in combating pseudoscience, nutrition researchers, policy makers, and practitioners must work together, and the role of practitioners in translating the evidence base and personalizing it to individual patients must be emphasized. Continuing to address current challenges, including increasing the timeliness and consistency of the approach to the evidence base, is required to ensure informed and robust nutrition policy, research, and practice into the future.

Users, Uses, and Effects of Social Media in Dietetic Practice: Scoping Review of the Quantitative and Qualitative Evidence.
Dumas, AA, Lapointe, A, Desroches, S
Journal of medical Internet research. 2018;(2):e55
Abstract
BACKGROUND Social media platforms are increasingly used by registered dietitians (RDs) to improve knowledge translation and exchange in nutrition. However, a thorough understanding of social media in dietetic practice is lacking. OBJECTIVE The objective of this study was to map and summarize the evidence about the users, uses, and effects of social media in dietetic practice to identify gaps in the literature and inform future research by using a scoping review methodology. METHODS Stages for conducting the scoping review included the following: (1) identifying the research question; (2) identifying relevant studies through a comprehensive multidatabase and gray literature search strategy; (3) selecting eligible studies; (4) charting the data; and (5) collating, summarizing, and reporting results for dissemination. Finally, knowledge users (RDs working for dietetic professional associations and public health organizations) were involved in each review stage to generate practical findings. RESULTS Of the 47 included studies, 34 were intervention studies, 4 were descriptive studies, 2 were content analysis studies, and 7 were expert opinion papers in dietetic practice. Discussion forums were the most frequent social media platform evaluated (n=19), followed by blogs (n=13) and social networking sites (n=10). Most studies targeted overweight and obese or healthy users, with adult populations being most studied. Social media platforms were used to deliver content as part of larger multiple component interventions for weight management. Among intervention studies using a control group with no exposition to social media, we identified positive, neutral, and mixed effects of social media for outcomes related to users' health behaviors and status (eg, dietary intakes and body weight), participation rates, and professional knowledge. Factors associated with the characteristics of the specific social media, such as ease of use, a design for quick access to desired information, and concurrent reminders of use, were perceived as the main facilitators to the use of social media in dietetic practice, followed to a lesser extent by interactions with an RD and social support from fellow users. Barriers to social media use were mostly related to complicated access to the site and time issues. CONCLUSIONS Research on social media in dietetic practice is at its infancy, but it is growing fast. So far, this field of research has targeted few social media platforms, most of which were assessed in multiple-component interventions for weight management among overweight or obese adults. Trials isolating the effects and mechanisms of action of specific social media platforms are needed to draw conclusions regarding the effectiveness of those tools to support dietetic practice. Future studies should address barriers and facilitators related to the use of social media written by RDs and should explore how to make these tools useful for RDs to reach health consumers to improve health through diet.

Twelve key nutritional issues in bariatric surgery.
Thibault, R, Huber, O, Azagury, DE, Pichard, C
Clinical nutrition (Edinburgh, Scotland). 2016;(1):12-17
Abstract
In morbidly obese patients, i.e. body mass index ≥35, bariatric surgery is considered the only effective durable weight-loss therapy. Laparoscopic Roux-en-Y gastric bypass (LRYGBP), laparoscopic sleeve gastrectomy (LSG), and biliopancreatic diversion with duodenal switch (BPD-DS) are associated with risks of nutritional deficiencies and malnutrition. Therefore, preoperative nutritional assessment and correction of vitamin and micronutrient deficiencies, as well as long-term postoperative nutritional follow-up, are advised. Dietetic counseling is mandatory during the first year, optional later. Planned and structured physical exercise should be systematically promoted to maintain muscle mass and bone health. In this review, twelve key perioperative nutritional issues are raised with focus on LRYGBP and LSG procedures, the most common current bariatric procedures.
