RESUMO

Malignant cells remodel their metabolism to meet the demands of uncontrolled cell proliferation. These demands lead to differential requirements in energy, biosynthetic precursors, and signaling intermediates. Both genetic programs arising from oncogenic events and transcriptional programs and epigenomic events are important in providing the necessary metabolic network activity. Accumulating evidence has established that environmental factors play a major role in shaping cancer cell metabolism. For metabolism, diet and nutrition are the major environmental aspects and have emerged as key components in determining cancer cell metabolism. In this review, we discuss these emerging concepts in cancer metabolism and how diet and nutrition influence cancer cell metabolism.

RESUMO

The evolution of dietary guidelines from isolated nutrients to broader dietary pattern recommendations results from growing knowledge of the synergy between nutrients and their food sources as they influence health. Macronutrient and micronutrient needs can be met by consuming various dietary patterns, but guidance is often required to facilitate population-wide adherence to wise food choices to achieve a healthy dietary pattern. This is particularly true in this era with the proliferation of nutrition misinformation and misplaced emphasis. In 2021, the American Heart Association issued a scientific statement outlining key principles of a heart-healthy dietary pattern that could be operationalized in various ways. The objective of this scientific statement is to assess alignment of commonly practiced US dietary patterns with the recently published American Heart Association criteria, to determine clinical and cultural factors that affect long-term adherence, and to propose approaches for adoption of healthy dietary patterns. This scientific statement is intended to serve as a tool for clinicians and consumers to evaluate whether these popular dietary pattern(s) promote cardiometabolic health and suggests factors to consider when adopting any pattern to improve alignment with the 2021 American Heart Association Dietary Guidance. Numerous patterns strongly aligned with 2021 American Heart Association Dietary Guidance (ie, Mediterranean, DASH [Dietary Approaches to Stop Hypertension], pescetarian, vegetarian) can be adapted to reflect personal and cultural preferences and budgetary constraints. Thus, optimal cardiovascular health would be best supported by developing a food environment that supports adherence to these patterns wherever food is prepared or consumed.

RESUMO

Phenylketonuria is characterized by intellectual disability and behavioral, psychiatric, and movement disorders resulting from phenylalanine (Phe) accumulation. Standard-of-care treatment involves a Phe-restricted diet plus medical nutrition therapy (MNT), with or without sapropterin dihydrochloride, to reduce blood Phe levels. Pegvaliase is an injectable enzyme substitution treatment approved for adult patients with blood Phe >600 µmol/L despite ongoing management. A previous comparative effectiveness analysis using data from the Phase 3 PRISM trials of pegvaliase (NCT01819727 and NCT01889862) and the Phenylketonuria Demographics, Outcomes and Safety Registry (PKUDOS; NCT00778206) suggested that pegvaliase was more effective at lowering mean blood Phe levels than sapropterin + MNT or MNT alone at 1 and 2 years of treatment. The current work augments and complements the previous analysis by including additional follow-up from the completed studies, robust methods reflecting careful consideration of issues with the distribution of Phe, and alternative methods for adjustment that are important for control of potential confounding in comparative effectiveness. Median blood Phe levels were lower, and median intact protein intakes were higher, in the pegvaliase group (n = 183) than in the sapropterin + MNT (n = 82) and MNT (n = 67) groups at Years 1, 2, and 3. In the pegvaliase group, median blood Phe levels decreased from baseline (1244 µmol/L) to Year 1 (535 µmol/L), Year 2 (142 µmol/L), and Year 3 (167 µmol/L). In the sapropterin + MNT group, median blood Phe levels decreased from baseline (900 µmol/L) to Year 1 (588 µmol/L) and Year 2 (592 µmol/L), and increased at Year 3 (660 µmol/L). In the MNT group, median blood Phe levels decreased slightly from baseline (984 µmol/L) to Year 1 (939 µmol/L) and Year 2 (941 µmol/L), and exceeded baseline levels at Year 3 (1157 µmol/L). The model-estimated proportions of participants achieving blood Phe ≤600 µmol/L were 41%, 100%, and 100% in the pegvaliase group at Years 1, 2, and 3, respectively, compared with 55%, 58%, and 38% in the sapropterin + MNT group and 5%, 16%, and 0% in the MNT group. The estimated proportions of participants achieving more stringent blood Phe targets of ≤360 µmol/L and ≤120 µmol/L were also higher in the pegvaliase group than in the other groups at Years 2 and 3. Overall, our results indicate that, compared with standard therapy, pegvaliase induces a substantial, progressive, and sustained decrease in blood Phe levels - to a much greater extent than sapropterin + MNT or MNT alone - which is expected to improve long-term outcomes in patients with phenylketonuria.

RESUMO

BACKGROUND: Diabetes complicates ≤7% of pregnancies in the United States. Although medical nutrition therapy is the mainstay of diabetes treatment, many barriers exist to the successful implementation of dietary modifications. Home-delivered medically tailored meals (MTMs) are promising to overcome such barriers. OBJECTIVE: The objective of this study was to evaluate the feasibility and acceptability of home-delivered MTM in pregnant patients with diabetes. METHODS: We performed a prospective cohort study of home-delivered MTM for pregnant patients with diabetes using a mixed-methods approach. Participants <35 wk of gestation at the time of enrollment received weekly home delivery of diabetes-specific meals. Qualitative semistructured interviews were conducted to gain insight into participants' experience. Diabetes self-efficacy was assessed pre- and postintervention using the Diabetes Self-Efficacy Scale and 2-Item Diabetes Distress Screening Scale. The difference in mean scores was compared using t-tests with P value of <0.05 considered significant. Feasibility and acceptability were evaluated through participants' attitude toward MTM in qualitative interviews and indirectly evaluated through diabetes self-efficacy surveys. RESULTS: Twenty pregnant people with diabetes who received home-delivered MTM during pregnancy were interviewed postpartum. Participants found this program convenient for various reasons, including reduced time for grocery shopping and preparing meals. Participants were satisfied with meals, citing a positive impact on diabetes management, accessibility of healthy foods, reduced stress with meal planning, and greater perceived control of blood glucose. Most participants shared meals with their families or received specific meals for their dependents, which was positively received. Reduced financial and mental stress was also widely reported. Diabetes self-efficacy was significantly improved postintervention with MTM. CONCLUSION: Home-delivered MTM is feasible and acceptable in pregnant patients with diabetes and may improve diabetes self-efficacy. Individual experiences offered insight into various barriers overcome by using this service. Home-delivered MTM may help ensure an accessible, healthy diet for pregnant patients with diabetes.

RESUMO

Obesity is a complex chronic disease with increasing prevalence across the globe. Medical nutrition therapy (MNT) is an important component of obesity treatment, and low-calorie diets (LCDs) and very-low-calorie diets (VLCDs) are part of the MNT toolbox. This narrative review focuses on the latest evidence and clinical guidelines regarding the use and impact of meal replacements (MRs) as part of LCDs/VLCDs for the treatment of obesity and some associated complications. MRs can be used in conjunction with food as partial diet replacement (PDR) or can be used exclusively to serve as the sole source of dietary energy (total diet replacement [TDR]). Use of MR may be associated with better control of cravings and hunger typically observed during reduced calorie intake through effects of ketosis or stimuli narrowing, although the exact mechanisms for these effects remain unclear. Several clinical guidelines have endorsed the use of MRs as a part of MNT for obesity, primarily based on evidence that shows an average weight reduction of ~10 kg or more with TDR over at least 12 months in large, randomized controlled trials. When compared to usual care controls, these effects are 6-8 kg greater, and when compared to food-based diets, the effects are nearly twice the effect of a food-based diet. MR-based diets have been found to be safe and associated with improvements in quality of life. These diets are also effective for improving key cardiometabolic health outcomes, including dysglycaemia, blood pressure, lipids, and metabolic associated fatty liver. The effectiveness, safety, and associated health improvement makes MRs use a valuable strategy for several higher risk clinical scenarios where weight reduction is indicated.

RESUMO

Nutrition knowledge (NK) impacts food choices and may be improved through educational programmes. Identifying knowledge gaps related to NK among adolescent athletes may guide future nutrition education programmes. This review aimed to systematically review the level of NK in adolescent athletes based on the currently available published literature. The protocol for this review was registered with PROSPERO (CRD42022321765). A literature search was conducted in April 2022 using MEDLINE, CINAHL, SPORTDiscus, Web of Science and SCOPUS databases. The study design was not restricted, provided that a quantitative NK score was reported for adolescent athletes. Studies were limited to the English language and published between 2010 and April 2022. Studies were assessed for quality and risk of bias using the Academy of Nutrition and Dietetics Quality Appraisal Checklist. Data extracted included demographics, questionnaire name, number of items, validation status and mean total and subsection NK scores. Meta-analyses were inappropriate due to the heterogeneity of NK assessment tools; therefore, results were presented narratively. Thirty-two studies that assessed NK of 4553 adolescent athletes and 574 comparison participants were included. Critical appraisal of studies resulted in neutral rating 'moderate quality' for most (n 30) studies. Studies lacked justification for sample size and often used inadequately validated questionnaires. NK scores ranged from poor (33·3 %) to excellent (90·6 %). The level of NK across studies is difficult to determine due to heterogenous questionnaires often lacking appropriate validation. NK should be assessed using tools validated in the relevant population or revalidated tools previously used for other populations.

RESUMO

This Position Paper from the Academy of Nutrition Sciences is the third in a series which describe the nature of the scientific evidence and frameworks that underpin nutrition recommendations for health. This paper focuses on evidence which guides the application of dietary recommendations for individuals. In some situations, modified nutrient intake becomes essential to prevent deficiency, optimise development and health, or manage symptoms and disease progression. Disease and its treatment can also affect taste, appetite and ability to access and prepare foods, with associated financial impacts. Therefore, the practice of nutrition and dietetics must integrate and apply the sciences of food, nutrition, biology, physiology, behaviour, management, communication and society to achieve and maintain human health. Thus, there is huge complexity in delivering evidence-based nutrition interventions to individuals. This paper examines available frameworks for appraising the quality and certainty of nutrition research evidence, the development nutrition practice guidelines to support evidence implementation in practice and the influence of other sources of nutrition information and misinformation. The paper also considers major challenges in applying research evidence to an individual and suggests consensus recommendations to begin to address these challenges in the future. Our recommendations target three groups; those who deliver nutrition interventions to individuals, those funding, commissioning or undertaking research aimed at delivering evidence-based nutrition practice, and those disseminating nutritional information to individuals.

RESUMO

Most randomized controlled studies on nutrition in intensive care patients did not yield conclusive results or were neutral or negative concerning the primary endpoints but also in most secondary endpoints. However, there is a consistent observation that in several of these studies there was a negative effect of the nutrition intervention on the kidneys in one of the study arms. During the early phase and in unstable periods during further course of disease an inadequate clinical nutrition can damage the kidneys, can elicit or aggravate acute kidney injury and/ or increase requirements of renal replacement therapy (RRT). This relates to total energy intake, glucose intake/hyperglycemia and protein/ amino acid intake at various stages of renal dysfunction. The kidney could present a critical organ system for guiding nutrition therapy, a close monitoring of kidney function should be observed and nutrition therapy may need to be adapted accordingly. The long-held dogma of performing full nutrition and accept an otherwise not necessary RRT is definitely to be refuted.

RESUMO

AIM: Colorectal cancer (CRC) patients need CRC-specific dietary guidance, but often lack access to adequate nutritional information and support. This scoping review identified study interventions, online resources, which have been produced to support nutritional care self-management for CRC patients from diagnosis, through treatment and into survivorship and guidelines to underpin these. METHODS: The review was carried out in accordance with the JBI method for Scoping Reviews. Study interventions, online resources that support the self-management of nutrition and diet in CRC patients were eligible for inclusion, along with CRC-specific guidelines. Searches up to February 2023, were carried out via MEDLINE, CINAHL, PsycInfo, Embase, and Web of Science for published literature and ProQuest Dissertations, Theses Global, TRIP Medical Database, and Google search engines for grey literature. Two reviewers independently screened titles and abstracts, and relevant full texts for inclusion. Data were analysed descriptively. RESULTS: Eight study interventions, 74 online resources and three guidelines specifically aimed at CRC patients were included in the review. Study interventions were heterogenous with respect to duration, whether it was personalized, who supported delivery and which guidelines underpinned the intervention. Three study interventions resulted in improved quality of life and one lengthened survival. A total of 36 (48.6%) online resources were produced by UK charity organizations. Most of the included information was for patients after completing treatment. Specific advice for patients with a stoma was lacking. Some of the online resources provided conflicting advice. The three guidelines explained how dietary adjustments can help address symptoms related to cancer or treatment and two provided more specific guidance on making dietary changes, with specific examples of how to tailor dietary advice to patient needs. CONCLUSION: This scoping review of study interventions, online resources, and guidelines highlighted the need for reliable, detailed, and personalized information to help CRC patients to self-manage their nutritional care.

RESUMO

BACKGROUND: Stroke patients often face disabilities that significantly interfere with their daily lives. Poor nutritional status is a common issue amongst these patients, and malnutrition can severely impact their functional recovery post-stroke. Therefore, nutritional therapy is crucial in managing stroke outcomes. However, its effects on disability, activities of daily living (ADL), and other critical outcomes have not been fully explored. OBJECTIVES: To evaluate the effects of nutritional therapy on reducing disability and improving ADL in patients after stroke. SEARCH METHODS: We searched the trial registers of the Cochrane Stroke Group, CENTRAL, MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1982), and AMED (from 1985) to 19 February 2024. We also searched trials and research registries (ClinicalTrials.gov, World Health Organization International Clinical Trials Registry Platform) and reference lists of articles. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that compared nutritional therapy with placebo, usual care, or one type of nutritional therapy in people after stroke. Nutritional therapy was defined as the administration of supplemental nutrients, including energy, protein, amino acids, fatty acids, vitamins, and minerals, through oral, enteral, or parenteral methods. As a comparator, one type of nutritional therapy refers to all forms of nutritional therapies, excluding the specific nutritional therapy defined for use in the intervention group. DATA COLLECTION AND ANALYSIS: We used Cochrane's Screen4Me workflow to assess the initial search results. Two review authors independently screened references that met the inclusion criteria, extracted data, and assessed the risk of bias and the certainty of the evidence using the GRADE approach. We calculated the mean difference (MD) or standardised mean difference (SMD) for continuous data and the odds ratio (OR) for dichotomous data, with 95% confidence intervals (CIs). We assessed heterogeneity using the I2 statistic. The primary outcomes were disability and ADL. We also assessed gait, nutritional status, all-cause mortality, quality of life, hand and leg muscle strength, cognitive function, physical performance, stroke recurrence, swallowing function, neurological impairment, and the development of complications (adverse events) as secondary outcomes. MAIN RESULTS: We identified 52 eligible RCTs involving 11,926 participants. Thirty-six studies were conducted in the acute phase, 10 in the subacute phase, three in the acute and subacute phases, and three in the chronic phase. Twenty-three studies included patients with ischaemic stroke, three included patients with haemorrhagic stroke, three included patients with subarachnoid haemorrhage (SAH), and 23 included patients with ischaemic or haemorrhagic stroke including SAH. There were 25 types of nutritional supplements used as an intervention. The number of studies that assessed disability and ADL as outcomes were nine and 17, respectively. For the intervention using oral energy and protein supplements, which was a primary intervention in this review, six studies were included. The results for the seven outcomes focused on (disability, ADL, body weight change, all-cause mortality, gait speed, quality of life, and incidence of complications (adverse events)) were as follows: There was no evidence of a difference in reducing disability when 'good status' was defined as an mRS score of 0 to 2 (for 'good status': OR 0.97, 95% CI 0.86 to 1.10; 1 RCT, 4023 participants; low-certainty evidence). Oral energy and protein supplements may improve ADL as indicated by an increase in the FIM motor score, but the evidence is very uncertain (MD 8.74, 95% CI 5.93 to 11.54; 2 RCTs, 165 participants; very low-certainty evidence). Oral energy and protein supplements may increase body weight, but the evidence is very uncertain (MD 0.90, 95% CI 0.23 to 1.58; 3 RCTs, 205 participants; very low-certainty evidence). There was no evidence of a difference in reducing all-cause mortality (OR 0.57, 95% CI 0.14 to 2.28; 2 RCTs, 4065 participants; low-certainty evidence). For gait speed and quality of life, no study was identified. With regard to incidence of complications (adverse events), there was no evidence of a difference in the incidence of infections, including pneumonia, urinary tract infections, and septicaemia (OR 0.68, 95% CI 0.20 to 2.30; 1 RCT, 42 participants; very low-certainty evidence). The intervention was associated with an increased incidence of diarrhoea compared to usual care (OR 4.29, 95% CI 1.98 to 9.28; 1 RCT, 4023 participants; low-certainty evidence) and the occurrence of hyperglycaemia or hypoglycaemia (OR 15.6, 95% CI 4.84 to 50.23; 1 RCT, 4023 participants; low-certainty evidence). AUTHORS' CONCLUSIONS: We are uncertain about the effect of nutritional therapy, including oral energy and protein supplements and other supplements identified in this review, on reducing disability and improving ADL in people after stroke. Various nutritional interventions were assessed for the outcomes in the included studies, and almost all studies had small sample sizes. This led to challenges in conducting meta-analyses and reduced the precision of the evidence. Moreover, most of the studies had issues with the risk of bias, especially in terms of the absence of blinding and unclear information. Regarding adverse events, the intervention with oral energy and protein supplements was associated with a higher number of adverse events, such as diarrhoea, hyperglycaemia, and hypoglycaemia, compared to usual care. However, the quality of the evidence was low. Given the low certainty of most of the evidence in our review, further research is needed. Future research should focus on targeted nutritional interventions to reduce disability and improve ADL based on a theoretical rationale in people after stroke and there is a need for improved methodology and reporting.

RESUMO

INTRODUCTION: Although nutritional therapy may be able to enable intensive care unit (ICU) survivors to return home instead of being discharged to a rehabilitation facility, post-ICU discharge nutritional therapy lacks investigation. This study evaluated the impact of nutritional therapy after ICU on discharge destination in critically ill patients. METHODS: We enrolled consecutive adult patients who spent >72 h in the ICU from December 2020 to March 2023. The primary outcome was discharge destination. Energy and protein intake during the ICU stay and on days 7 and 14 after ICU discharge were evaluated. The target protein intake during the intensive treatment and general ward phases were 0.8 and 1.0 g/kg/day, respectively. Patients were categorized into home discharge (group A) and rehabilitation transfer (group B) groups. Factors affecting the discharge destination were evaluated using logistic regression analysis. RESULTS: Of the 183 patients included, 134 belonged to group A and 49 to group B. In group A, more patients reached the protein intake target than in group B. Logistic regression analysis identified achieving the protein intake target as an independent predictor of home discharge. CONCLUSION: Further studies are required to confirm the relationship between nutritional therapy during general ward and patient outcomes.

RESUMO

BACKGROUND: The primary objective of this cross-sectional retrospective study was to describe the implementation of dietitian prescribed nutrition recommendations in malnourished paediatric patients in the hospital and ambulatory settings. We also aimed to investigate other characteristics that could be associated with differences in implementation. METHODS: Data were collected from 186 hospitalised and 565 ambulatory patients between February 2020 and January 2021. Data included age, hospital or ambulatory specialty departments, primary diagnosis, malnutrition status, hospital length of stay (LOS), and medical nutrition therapy recommendations. Implementation by the medical team in the hospital setting and adherence by the family in the outpatient setting were categorised as "Full", "Partial" or "None". "Partial" and "None" were combined for analysis. RESULTS: Dietitian prescribed recommendations were implemented in 79.6% of hospitalised patients. In the ambulatory population, 46.4% of patients were adherent with nutrition recommendations. Within the hospital, there was a significant difference in implementation of nutrition recommendations based on age (p = 0.047), hospital department (p = 0.002) and LOS (p = 0.04), whereas, in the ambulatory population, there were no significant differences in the rate of adherence among any of the studied characteristics. CONCLUSIONS: Dietitian recommendations are frequently implemented in the hospital, whereas adherence to such recommendations is poor in the outpatient population. Interventions to improve adherence to nutrition recommendations in the ambulatory setting are needed.

RESUMO

BACKGROUND: Nutritional prehabilitation may improve haematopoietic cell transplantation (HCT) outcomes, although little evidence exists. The present study aimed to understand healthcare professional (HCP) perceptions of prehabilitation and nutritional care pre-HCT in UK centres. METHODS: An anonymous online survey (developed and refined via content experts and piloting) was administered via email to multidisciplinary HCPs in 39 UK adult centres, between July 2021 and June 2022. Data are presented as proportions of responses. Routine provision denotes that care was provided >70% of time. RESULTS: Seventy-seven percent (n = 66) of HCPs, representing 61.5% (n = 24) of UK adult HCT centres, responded. All HCPs supported prehabilitation, proposing feasible implementation between induction chemotherapy (60.4%; n = 40) and first HCT clinic (83.3%; n = 55). Only 12.5% (n = 3) of centres had a dedicated prehabilitation service. Nutrition (87.9%; n = 58), emotional wellbeing (92.4%; n = 61) and exercise (81.8%; n = 54) were considered very important constituents. HCPs within half of the HCT centres (n = 12 centres) reported routine use of nutrition screening pre-HCT with a validated tool; 66.7% of HCPs (n = 36) reported using the malnutrition universal screening tool (MUST). Sixty-two percent (n = 41) of HCPs reported those at risk, received nutritional assessments, predominantly by dietitians (91.6%; n = 22) using the dietetic care process (58.3%; n = 14). Body mass index (BMI) was the most frequently reported body composition measure used by HCPs (70.2%, n = 33). Of 59 respondents, non-dietitians most routinely provided dietary advice pre-HCT (82.4%; n = 28 vs. 68%; n = 17, p = 0.2); including high-energy/protein/fat and neutropenic diet advice. Prophylactic enteral feeding pre-HCT was rare, indicated by low BMI and significant unintentional weight loss. Just under half (n = 25 of 59, 42.4%) HCPs reported exercise advice was given routinely pre-HCT. CONCLUSIONS: Nutrition and prehabilitation pre-HCT are considered important and deliverable by HCPs, but current provision in UK centres is limited and inconsistent.

RESUMO

Nutrition has played a central role in the management and outcomes of people with cystic fibrosis (pwCF) since the 1970s. Advances in therapies and practices in recent decades have led to a significant change in the patient landscape with dramatic improvements in life expectancy, as well as quality of life, bringing with it new issues. Historically, cystic fibrosis was a condition associated with childhood and malnutrition; however, changes in patient demographics, nutritional assessment and fundamental nutritional management have evolved, and it has become an increasingly prevalent adult disease with new nutritional challenges, including obesity. This paper aims to describe these changes and the impact and challenges they bring for those working in this field. Nutritional professionals will need to evolve, adapt and remain agile to the wider range of situations and support required for a new generation of pwCF. Specialised nutrition support will continue to be required, and it will be additionally important to improve and optimise quality of life and long-term health.

RESUMO

OBJECTIVE: Internet search engines and social media websites are prominent and growing sources of dietary information for people with chronic kidney disease (CKD) and their healthcare providers. However, nutrition therapy for CKD is undergoing a paradigm shift, which may lead to inconsistent advice for managing hyperphosphatemia. The aim of this study was to summarize and evaluate online resources for phosphorus-specific nutrition therapy. DESIGN AND METHODS: Patient-facing resources were collected from Google, Yahoo, and Facebook in June-July 2021. Using nine independent search terms, the first 100 hits were reviewed. Dietary advice for food types, food groups, food subgroups, and individual food items was categorized as "restricted," "recommended," "mixed," and "not mentioned." Information on publication date, source, and author(s), phosphorus bioavailability, and demineralization were also collected. RESULTS: After removing duplicates, 199 resources from Google and Yahoo and 33 from Facebook were reviewed. Resources ranged from 2005 to 2021 and were primarily authored by registered dietitians and medical doctors (65% and 31%, respectively). Dietary advice mostly focuses on restricting high-phosphorus foods and phosphorus additive-based processed foods. Dietary restrictions were generally consistent with the traditional low-phosphorus diet, which targets whole grains, dairy, and plant-based protein foods, although major inconsistencies were noted. Phosphorus bioavailability and demineralization were rarely mentioned (16% and 8%, respectively). Similar findings were found on Facebook, but the limited number of resources limited meaningful comparisons. CONCLUSION: Results showed that online resources for phosphorus-specific nutrition therapy are highly restrictive of heart-healthy food items and contain significant inconsistencies. Given the widespread and increasing use of online resources by people with CKD and health care professionals to inform dietary choices, efforts are urgently needed to establish consensus for phosphorus-specific nutrition therapy. Until then, the findings of this study provide a basis for increasing awareness of the potential for confusion arising from online resources.

RESUMO

Medical nutrition therapy (MNT) is the foundation of the comprehensive treatment of patients with diabetes. In 2010, the Chinese Clinical Nutritionist Center of the Chinese Medical Doctor Association developed the first Chinese guideline on MNT for patients with diabetes, and it was updated in 2015. Since then, new evidence has emerged in the field of MNT and metabolic therapy in patients with diabetes. The Nutrition and Metabolic Management Branch of the China International Exchange and Promotive Association for Medical and Health Care organized a team of experts from related institutions, including the Clinical Nutrition Branch of the Chinese Nutrition Society, Chinese Diabetes Society, Chinese Society for Parenteral and Enteral Nutri-tion, and Chinese Clinical Nutritionist Center of the Chinese Medical Doctor Association. Their task was to develop the Chinese Guidelines of Medical Nutrition Therapy in Diabetes (2022 Edition) in accordance with the requirements of the Guidelines for the Formulation/Revision of Clinical Guidelines in China (2022 Edition) by combining the questions raised and evidence gathered in clinical practices in China, to guide and standardize the clinical MNT.

RESUMO

BACKGROUND AND OBJECTIVES: A comprehensive nutritional management is necessary for favourable outcomes in patients with chronic kidney disease (CKD). We aimed to assess the changes in nutritional status and disease progression with nutritional management where renal replacement therapy (RRT) was not in place. METHODS AND STUDY DESIGN: A quasi-experiment intervention was conducted on 70 CKD patients at stages 3-5 from July to December 2022. Participants were excluded if they underwent RRT, including dialy-sis (hemodialysis or peritoneal dialysis), or kidney transplantation. The nutritional regimen covered nutrition-al counseling, samples of the dietary menu, and supplement products. We evaluated nutritional status using Subjective Global Assessment (SGA) scale and sub-clinical blood test at T0 (hospital admission) and T1 (two weeks after the admission or 24 hours before the discharge). RESULTS: After the intervention, the number of patients classified as malnutrition or at risk of malnourished reduced significantly (65.7% to 54.3% and 25.7% and 5.7%, respectively). The serum concentration of urea, creatinine and parathyroid hormone decreased remarkably, especially in patients receiving nutritional management. In the intervention group, the dietary pattern provided increased intakes of calcium and iron at T1, while phosphorus, sodium and potassium decreased after follow-up. Nausea/vomiting, loss of appetite, tiredness and sleep disorders were improved in the intervention compared to the control group. CONCLUSIONS: Nutritional therapy enhanced the nutritional sta-tus, and quality of dietary and renal function in CKD patients without RRT. Applying nutrition education and treatment at an early stage can slow CKD progression, which should be applicable elsewhere in Vietnam.

RESUMO

BACKGROUND AND OBJECTIVES: Study aim was to determine the levels and barriers of the Nutrition Care Process (NCP), a practical method of individualized nutrition support. METHODS AND STUDY DESIGN: Delegate of registered dietitians (RDs) from acute-care hospitals answered our nationwide web-based questionnaire (April-June, 2023) to determine the implementation status of screening, assessment, intervention (including planning), and monitoring (components of the NCP). RESULTS: Of 5,378 institutions contacted, 905 (16.8%) responded. For Screening, 80.0% screened all inpatients: primary personnel in charge were RDs (57.6%); the most used screening tool was Subjective Global Assessment (SGA) (49.2%). For Assessment, 66.1% assessed all inpatients: food intake (93.3%) was most evaluated whereas muscle mass and strength (13.0%, 8.8%) were least evaluated. For Intervention, 43.9% did so within 48h of hospital admission: oral nutritional supplement (92.9%) was the most common RDs intervention and parenteral nutrition (29.9%) was used less. For Monitoring, 18.5% of institutions had monitoring frequency of ≥ 3 times/week whilst 23.0% had monitoring less than once a week for severely malnourished patients. Energy and protein intake (93.7%, 84.3%) were most monitored and lipid intake (30.1%) was less monitored. CONCLUSIONS: Barriers of NCP included inefficient staffing systems and unsuitable tools in Screening, inaccurate patient targeting and lack of important evaluation items in Assessment, delayed timing and incomplete contents in Intervention, and inadequate fre-quency and lack of important evaluation items in Monitoring. An increase in RDs staffing in acute-care general wards, widespread NCP instruction manuals, and education about the tools and evaluation items utilized in nutritional management are possible solutions.

RESUMO

AIMS: This scoping review aimed to identify and map the available information on the nutrition care process in older adults with delirium to analyse and summarise key concepts, and gaps, including the barriers and enablers to providing nutrition care for this group. DESIGN: Scoping review. METHODS: This review was conducted in accordance with the JBI methodology for scoping reviews. Published and grey sources in English were considered. DATA SOURCES: Databases searched were CINAHL, Medline, Embase, JBI Evidence-based Practice, Scopus, ProQuest and Google. The initial search was conducted from October 2021 to March 2022 and repeated in October 2023. RESULTS: The database search identified 1561 articles, 186 underwent full-text review and 17 articles were included. The grey literature search identified eight articles. Malnutrition and delirium were identified as mutually reinforcing, and nutrition strategies were included as part of multicomponent interventions for delirium management. There was no mention of barriers or enablers to nutrition care and minimal descriptive or empirical data available to guide nutrition care processes in this group. CONCLUSION: This scoping review revealed a need for further research into nutrition care processes in older patients with delirium, in particular the barriers and enablers, to inform appropriate management strategies in this vulnerable group. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Providing nutrition care for older patients with delirium is important and further practical guidance could help patients, healthcare staff and families. IMPACT: This scoping review yielded instructive data suggesting that delirium is an important risk factor for malnutrition and vice versa, which leads to poor patient and health service outcomes. REPORTING METHOD: This scoping review adhered to relevant EQUATOR guidelines and used the Preferred Reporting Items For Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). PATIENT OF PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMO

BACKGROUND: Disease-related malnutrition is prevalent among hospitalised patients, but not all patients achieve the needed nutritional care. At a Danish University Hospital, focus has been on implementing nutritional practices based on clinical guidelines, but there is continuously variation between the wards regarding the quality of nutritional care. AIM: The aim of this study was to identify the potential barriers and facilitators for implementation of the clinical guidelines for nutritional practices and to recommend suggestions for development of nutritional practices, using a theoretical implementation strategy. METHOD: The design was a qualitative interview study of employees at a Danish University Hospital, using a semi-structured interview guide. The participants were nurses, nurse's assistant, nurse nutrition expert, head nurse and dieticians. We recruited 11 employees, representing eight different wards. FINDINGS: The analysis identified six themes: (1) clear allocation of responsibilities and committed management enhances nutrition practices, (2) leadership support is essential, (3) physical settings and tools affect possibilities for action, (4) selection of equivalent staff is core, (5) teaching promotes the knowledge and skills and (6) a dietitian in the ward facilitates implementation of nutritional care. Barriers and facilitators among the themes were identified and has led to suggestions to strengthen nutritional care, based on implementation theory. CONCLUSION: Various factors were identified as having impact on the implementation of nutrition practices and different suggestions have emerged to accommodate those factors, as well as to apply an implementation strategy to facilitate change in practice.
