Effect of Oral Nutritional Supplementation on Health-Related Outcomes and Nutritional Biomarkers in Children and Adolescents with Undernutrition: A Systematic Review and Meta-Analysis.

This systematic review aims to synthesize scientific evidence on the effects of oral nutritional supplementation (ONS) on health-related outcomes and nutritional biomarkers among children and adolescents with undernutrition. The review protocol was reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. A comprehensive keyword and reference search was conducted in seven electronic bibliographic databases: PubMed, Academic Search Complete, Academic Search Premier, CINAHL, Global Health, Web of Science, and Scopus. We identified 14 peer-reviewed articles reporting results from 13 unique studies (eight randomized controlled trials, four pre-post studies, and one observational study). Study participants were recruited from 14 countries/regions, with ages ranging from 1 to 14 years. Outcomes of interest include health-related outcomes (acute diseases and infections) and nutritional biomarkers (e.g., serum iron and zinc). Six of the eight studies examining acute diseases/infections and five of the seven examining nutritional biomarkers reported statistically significant improvement in some, but not all, outcomes. A meta-analysis of three studies found that ONS interventions reduce the incidence of upper respiratory tract infection (URTI) by 39% (95% CI, 0.42-0.91) in children at nutritional risk when compared to dietary counseling (DC) alone. This systematic review suggests that ONS interventions can improve certain health-related outcomes and nutritional biomarkers in undernourished children and adolescents. Specifically, the use of ONS significantly reduces the risk of URTI, highlighting its potential to enhance immune function and break the cycle of undernutrition and infection.

Nutritional therapy for reducing disability and improving activities of daily living in people after stroke.

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.

[The challenge of nutrition in palliative care: Eating and drinking - beneficial even at the end of life?] / Herausforderung Ernährung in palliativen Situationen.

INTRODUCTION: Food and nutrition play a major role in our lives. They include physical, psychological as well as cultural and social aspects. Illnesses increase the risk of altered food intake/absorption - of malnutrition. This applies in particular to palliative situations. The causes of malnutrition can be diverse. Malnutrition often leads to reduced performance and can therefore have a major impact on the quality of life and independency of patients. The aim of nutritional therapy interventions is therefore to maintain or improve the quality of life of patients with a life-threatening illness. The initially defined goals can change as the disease progresses. At the beginning of a life-threatening illness, adequate nutritional interventions are usually very effective. However, the benefits of nutritional therapy often change as the disease progresses and they often lose importance. For this reason, decision-making is an important process: Depending on the phase of illness, the prognosis and the patient's preferences, the nutritional therapy interventions needs to be reconsidered in regard of indication, individual benefit and the desired treatment goal on a regular base. As every medical intervention, nutritional therapy must regularly be adapted to the treatment goal if necessary.

Effect of Diet Counseling on Nutritional Status of Chronic Respiratory Diseases Patients Enrolled in the Pulmonary Rehabilitation Program in a Teaching Hospital: A Pre-Post Intervention Study.

We conducted the study to assess the effect of patient-tailored diet counseling on the nutritional status of chronic respiratory disease (CRD) patients under the pulmonary rehabilitation program from June 2021-May 2022. These patients completed 2 months of patient-tailored diet counseling sessions under the pulmonary rehabilitation program, which consisted of 4-5 interactive diet counseling sessions fortnightly. The pre- and postassessment was done using standardized outcomes: Malnutrition Universal Screening Tool (MUST), body mass index (BMI), and ideal body weight. The study enrolled 110 CRD patients. There was a statistically significant improvement in pre- and postassessment in MUST score, appetite, and unintentional weight loss (P < 0.001). Most of the patient's BMI normalized. In prenutritional assessment, most of the patients were malnourished and in postassessment, the number of malnourished and anemic patients was reduced. This study concludes that nutritional counseling effectively improves nutritional status and anemia.

Inadequate Dietary Education and Poor Adherence to a High Protein, Low Sodium Diet in Cirrhosis: Mixed Methods Approach.

BACKGROUND: Malnutrition in cirrhosis is associated with poor outcomes, leading to guidelines for a high protein, low sodium diet; however, there is no guidance regarding the implementation of diet education in clinical practice. METHODS: A mixed methods study enrolled 21 patients with cirrhosis and their caregivers. Semi-structured interviews on barriers and facilitators of dietary education and adherence were conducted. Demographic and clinical data were obtained, along with quantitative measures of dietary adherence, including 24-h food recall and spot urine sodium. Combined deductive and inductive coding was used to identify qualitative themes, along with a quantitative assessment of interviews. Quantitative data was reported using descriptive statistics with frequencies, mean and confidence intervals. RESULTS: Participants were mostly male (16/21) with a mean age 57.8 years (SE 2.8) and MELD-Na 9 (SE 1.2). 4 themes emerged: 1. More than 50% of participants and caregivers endorsed no or inadequate diet education 2. They reported mostly negative experiences with dietary adherence with largest impact on social life 3. Facilitators of adherence included the presence of household support and fear of complications of cirrhosis 4. Overwhelmingly desired non-generic handouts and information. Dietary adherence was poor with only one participant meeting protein and sodium requirements based on food recall. Four participants who adhered to < 2000 mg sodium had inadequate daily caloric intake. CONCLUSIONS: Dietary education is inadequate, and adherence to dietary recommendations is poor in patients with cirrhosis. Future studies should use these barriers and facilitators for intervention development.

Enhancing physical function and activity level in malnourished older adults through oral nutrition supplements: a randomized controlled trial.

BACKGROUND: Malnutrition of older individuals, leads to significant functional decline, reducing their quality of life. Lifestyle interventions; dietary improvements and supplementation are explored to enhance the physical function of older adults. The current study aimed to assess the impact of oral nutritional supplements (ONS) on the functional and activity levels of Sri Lankan older adults. METHODS: This randomized controlled trial included; an intervention group (IG) receiving 200 mL of ONS providing 247 kcal per serving, for 12 weeks and a control group (CG) receiving an equivalent volume of water. Changes in handgrip strength, knee extension strength, gait speed, functional and activity levels were assessed. RESULTS: The IG showed significant improvements in handgrip strength (43.96 ± 18.61 kg vs. 32.81 ± 17.92 kg; p < 0.001) and knee extension strength (23.45 ± 2.29 kg vs. 16.41 ± 2.09 kg; p < 0.001) following 12 weeks compared to the CG. The IG also exhibited significant improvements in gait speed (1.31 ± 0.52 m/s vs. 0.87 ± 0.26 m/s), Barthel index score, (0.30 ± 0.47 vs. -0.18 ± 0.66), PASE score (0.52 ± 17.79 vs. -1.60 ± 21.77) and IPAQ categories. CONCLUSIONS: ONS was found to be effective in improving the functional and physical activity levels of malnourished older adults. TRIAL REGISTRATION: Sri Lanka Clinical Trial Registry SLCTR/2022/021.

Legume-supplemented feed for children hospitalised with severe malnutrition: a phase II trial.

Children hospitalised with severe malnutrition have high mortality and readmission rates post-discharge. Current milk-based formulations target restoring ponderal growth but not the modification of gut barrier integrity or microbiome which increases the risk of gram-negative sepsis and poor outcomes. We propose that legume-based feeds rich in fermentable carbohydrates will promote better gut health and improve overall outcomes. We conducted an open-label phase II trial at Mbale and Soroti Regional Referral Hospitals, Uganda, involving 160 children aged 6 months to 5 years with severe malnutrition (mid-upper arm circumference (MUAC) < 11·5 cm and/or nutritional oedema). Children were randomised to a lactose-free, chickpea-enriched legume paste feed (LF) (n 80) v. WHO standard F75/F100 feeds (n 80). Co-primary outcomes were change in MUAC and mortality to day 90. Secondary outcomes included weight gain (> 5 g/kg/d), de novo development of diarrhoea, time to diarrhoea and oedema resolution. Day 90 MUAC increase was marginally lower in LF v. WHO arm (1·1 cm (interquartile range (IQR) 1·1) v. 1·4 cm (IQR 1·40), P = 0·09); day 90 mortality was similar (11/80 (13·8 %) v. 12/80 (15 %), respectively, OR 0·91 (95 % CI 0·40, 2·07), P = 0·83). There were no differences in any of the other secondary outcomes. Owing to initial poor palatability of the LF, ten children switched to WHO feeds. Per-protocol analysis indicated a trend to lower day 90 mortality and readmission rates in the LF (6/60 (10 %) and 2/60(3 %)) v. WHO feeds (12/71(17·5 %) and 4/71(6 %)). Further refinement of LF and clinical trials are warranted, given the poor outcomes in children with severe malnutrition.

Nutritional Support in Malnourished Outpatients with Chronic Obstructive Pulmonary Disease (COPD): A Randomized Controlled Pilot Study.

(1) Background: The evidence for nutritional support in COPD is almost entirely based on ready-to-drink oral nutritional supplements (ONSs). This study aimed to explore the effectiveness of powdered ONSs alongside individualized dietary counseling in the management of malnutrition. (2) Methods: Malnourished outpatients with COPD were randomized to receive either routine care (Group A: counseling + recommended to purchase powdered ONSs) or an enhanced intervention (Group B: counseling + provision of powdered ONSs at no cost to the patient) for 12 weeks. Outcomes of interest were nutritional intake, weight status, and quality of life. (3) Results: A total of 33 outpatients were included, categorized as follows: Group A (n = 21); Group B (n = 12); severely malnourished (n = 9), moderately malnourished (n = 24), mean BMI 18.0 SD 2.5 kg/m2. No differences were observed between groups at baseline or at week 12; however, analysis of the whole cohort (Group A + B) revealed nutrition intervention resulted in significant improvements in protein intake (+25.4 SD 53.4 g/d; p = 0.040), weight (+1.1 SD 2.6 kg; p = 0.032) and quality of life (-4.4 SD 10.0; p = 0.040). Only 41.2% of Group A and 58.3% of Group B reported consuming ONSs at week 12. Adherence to ONSs was associated with weight gain (+1.9 SD 2.5 kg vs. +0.4 SD 2.5 kg; p = 0.098). (4) Conclusions: Nutritional support results in significant improvements in nutrition status and quality of life in malnourished outpatients with COPD. However, improvements are associated with adherence to ONSs, suggesting the type of ONSs and how they are provided are important considerations in clinical practice and future studies.

A practical approach to nutritional intervention for people with chronic kidney disease in Vietnam.

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.

Low-Protein Diet in Elderly Patients with Chronic Kidney Disease Stage 4 and 5 in Conservative Management: Focus on Sarcopenia Development.

INTRODUCTION: Chronic kidney disease is a degenerative and increasingly prevalent condition that includes metabolic abnormalities and is associated with a higher risk of sarcopenia. The conservative approach points primarily to controlling metabolic issues and reducing the risk of malnutrition and sarcopenia, slowing the progression of kidney disease. The present study aims to evaluate the effect of a low-protein diet on malnutrition and sarcopenia. METHODS: A total of 45 patients (33 male and 12 female) aged over 70 with chronic kidney disease stage 4-5 in conservative management were considered. All patients had a dietary assessment and prescription of personalized low-protein dietary plans (≤0.6 g protein/kg) and a follow-up control between 4 and 6 months. In preliminary and follow-up evaluations, anthropometric data, blood examinations, body composition results, muscle strength, physical performance, and a 3-day food diary were collected. RESULTS: In the follow-up period, a significant weight loss (p = 0.001) and a decrease in body mass index (p = 0.002) were recorded. Food diaries revealed a significant reduction in protein, sodium, potassium, and phosphorus intake (p < 0.001), with a significant reduction in urea (p < 0.001) and proteinuria (p = 0.01) without any impact on lean mass (p = 0.66). Considerable variations in adherence between food diaries and the prescribed diet were also noted. CONCLUSIONS: Providing a personalized low-protein diet led to significant benefits in a short period without worsening the patient's nutritional status.

Effect of Fish-Based Diet on Malnourished Children: A Systematic Review.

Background: Malnutrition in children is mainly caused by the lack of protein and fat intake which harms their ability to grow and survive. Accurate data on the benefits of fish-based foods on the nutritional status of children is limited. The present systematic review aimed to provide an overview of published articles on the nutritional value of fish-based foods for children. Methods: A systematic review was performed during 2000-2021 by searching Science Direct, Cochrane Library, PubMed, ProQuest, and Wiley Online Library databases. The full text of selected articles in English was screened based on the inclusion and exclusion criteria. Included articles were all experimental studies (randomized control trial, quasi-randomized trial) or mixed methods studies involving malnourished children. The study was reported under the preferred reporting items for systematic reviews and meta-analyses guidelines. The risk of bias was assessed using the Cochrane tool. Results: A total of 330,859 articles were screened, out of which eight articles were included in the systematic review. Interventions included fish-based foods and beverages such as wafer bars, Jemawut-tuna cookies, Amizate in chocolate drink, dried fish powder, flaxseed oil supplemented with fish oil capsules, and porridge fortified with fish powder. Primary or secondary outcomes were the determination of zinc level, height growth, erythrocyte n-3 polyunsaturated fatty acid content, safety and acceptability, intestinal integrity, and cognitive development. The results showed that dried fish powder produced the most significant effect on body weight. Conclusion: The consumption of dried fish powder had positive effects on the recovery of malnourished children.

Nutrition interventions for body composition, physical function, cognition in hospitalized older adults: A systematic review of individuals 75 years and older.

BACKGROUND: Globally, the oldest old population is expected to triple by 2050. Hospitalization and malnutrition can result in progressive functional decline in older adults. Minimizing the impact of hospitalization on functional status in older adults has the potential to maintain independence, reduce health and social care costs, and maximize years in a healthy state. This study aimed to systematically review the literature to identify nutritional interventions that target physical function, body composition, and cognition in the older population (≥ 75 years). METHODS: A systematic review was conducted to evaluate the efficacy of nutritional interventions on physical function, body composition, and cognition in adults aged ≥ 75 years or mean age ≥80 years. Searches of PubMed (National Institutes of Health, National Library of Medicine), Scopus (Elsevier), EMBASE (Elsevier), Cumulative Index to Nursing and Allied Health Literature (CINAHL) with Full Text (EBSCOhost), and PsycInfo (EBSCOhost) were conducted. Screening, data extraction, and quality assessment were performed in duplicate and independently (CRD42022355984; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=355984). RESULTS: Of 8311 citations identified, 2939 duplicates were excluded. From 5372 citations, 189 articles underwent full-text review leaving a total of 12 studies for inclusion. Interventions were food-based, protein-based, carbohydrate-based, personalized, or used parenteral nutrition. Ten studies monitored anthropometric or body composition changes with three showing maintenance or improvements in lean mass, body mass index, triceps skinfold, and mid-upper arm circumference compared with the control group. Six studies monitored physical function but only the largest study found a beneficial effect on activities of daily living. Two of three studies showed the beneficial effects of nutritional intervention on cognition. CONCLUSION: There are few, high-quality, nutrition-based interventions in older adults ≥75 years. Despite heterogeneity, our findings suggest that large, longer-term (>2 weeks) nutritional interventions have the potential to maintain body composition, physical function, and cognition in adults aged 75 years and older during hospitalization.

Are dietitian recommendations followed? A descriptive study of paediatric hospitalised and ambulatory patients.

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.

Molecular characterization of stable QTL and putative candidate genes for grain zinc and iron concentrations in two related wheat populations.

KEY MESSAGE: Major QTL for grain zinc and iron concentrations were identified on the long arm of chromosomes 2D and 6D. Gene-based KASP markers were developed for putative candidate genes TaIPK1-2D and TaNAS10-6D. Micronutrient malnutrition is one of the most common public health problems in the world. Biofortification, the most attractive and sustainable solution to surmount malnutrition requires the development of micronutrient enriched new crop cultivars. In this study, two recombinant inbred line (RIL) populations, ZM175/XY60 and ZM175/LX987, were used to identify QTL for grain zinc concentration (GZnC), grain iron concentration (GFeC) and thousand grain weight (TGW). Eight QTL for GZnC, six QTL for GFeC and five QTL for TGW were detected. Three QTL on chromosomes 2DL and 4BS and chromosome 6A showed pleiotropic effects on all three traits. The 4BS and 6A QTL also increased plant height and might be Rht-B1a and Rht25a, respectively. The 2DL locus within a suppressed recombination region was identified in both RIL populations and the favorable allele simultaneously increasing GZnC, GFeC and TGW was contributed by XY60 and LX987. A QTL on chromosome 6DL associated only with GZnC was detected in ZM175/XY60 and was validated in JD8/AK58 RILs using kompetitive allele-specific PCR (KASP) marker K_AX-110119937. Both the 2DL and 6DL QTL were new loci for GZnC. Based on gene annotations, sequence variations and expression profiles, the phytic acid biosynthesis gene TaIPK1-2D and nicotianamine synthase gene TaNAS10-6D were predicted as candidate genes. Their gene-based KASP markers were developed and validated in a cultivar panel of 343 wheat accessions. This study investigated the genetic basis of GZnC and GFeC and provided valuable candidate genes and markers for breeding Zn- and Fe-enriched wheat.

Short-Term Acceptability of Ready-to-Use Therapeutic Foods in Two Provinces of Lao People's Democratic Republic.

BACKGROUND: In Lao PDR, acute malnutrition remains a public health problem, with around 9% of children under 5 being affected. Outpatient treatment of severe acute malnutrition requires ready-to-use therapeutic foods (RUTFs), but concerns have been raised about the acceptability of globally available products. Culturally acceptable RUTFs could be locally developed, but data are lacking on RUTF preferences in Lao PDR. METHODS: In a crossover-designed study, four different RUTFs were tested for short-term acceptability and organoleptic qualities (two globally available: peanut-based, which is the current standard, and wheat-milk-based RUTFs; two regionally produced: a mung-bean-based and a fish-rice-based RUTF). Organoleptic properties were evaluated by 83 caretaker-child pair participants through a taste test and a 30 min consumption test. Short-term acceptability was assessed through a 3-day intake test. The study sites were in Phongsaly (North Laos) and Attapeu (South Laos). Focus group discussions were conducted at the beginning and the end of the study. RESULTS: The mung bean RUTF was the favorite among caretakers, with an acceptability percentage of 96.2%, and scored better (p-value < 0.05) for all organoleptic variables than the other three RUTFs. Overall, 3 days after receiving take-home rations, the mean percentage of consumption was above 80% for all the RUTFs, with the mung bean product being the most consumed. CONCLUSIONS: The regionally produced mung bean RUTF was the most accepted, whereas the other regionally produced fish-based RUTF was the least accepted, showing the complexity of finding culturally acceptable solutions to fight malnutrition. For Lao PDR, a mung-bean-based RUTF seems the way forward, even if the current standard peanut-based RUTF appeared to be acceptable, albeit not the most preferred.

[Organoleptic evaluation of a diabetes-specific oral nutritional supplement with extra virgin olive oil in patients at nutritional risk and type 2 diabetes mellitus: Double-blind, randomized, crossover and multicenter clinical trial (DIACARE)]. / Evaluación sensorial de un suplemento nutricional oral específico para diabetes con aceite de oliva virgen extra en pacientes en riesgo nutricional y diabetes mellitus tipo 2: ensayo clínico doble ciego, aleatorizado, cruzado y multicéntrico (DIACARE.

Introduction: Introduction: oral nutritional supplements specific for diabetes (DSF) usually have a composition that favors their palatability and simultaneous glycemic and metabolic control. Objetive: to compare the sensory acceptability of a DSF with respect to a standard oral nutritional supplement (STF) in patients at risk of malnutrition with type 2 diabetes mellitus. Method: randomized, double-blind, crossover, multicenter, controlled, double-blind clinical trial. Odor, taste and perceived texture of a DSF and a STD were evaluated using a scale of 1 to 4. Results: twenty-nine patients were recruited and 58 organoleptic evaluations of the supplements were registered. A better evaluation of DSF was observed with respect to STD, although no statistically significant differences were reached: odor, 0.04 (CI 95 %) -0.49 to 0.56 (p = 0.092); taste, 0.14 (CI 95 %), -0.35 to 0.63 (p = 0.561); texture, 0.14 (CI 95 %), -0.43 to 0.72 (p = 0.619). No differences were found when analyzed by order of randomization, sex, degree of malnutrition, greater or lesser degree of complexity, greater or lesser time of evolution of diabetes, or by being older or younger. Conclusions: the specific nutritional supplement for diabetic patients formulated with extra virgin olive oil, EPA and DHA, a specific mixture of carbohydrates, and fiber, presented an adequate sensory acceptance by malnourished patients with type 2 diabetes mellitus.

Introducción: Introducción: las fórmulas nutricionales específicas para diabetes (FED) suelen presentar una composición que favorece simultáneamente su palatabilidad y el control glucémico y metabólico. Objetivo: comparar la aceptación sensorial de un FED respecto a un suplemento nutricional oral estándar (FE) en pacientes en riesgo de desnutrición con diabetes mellitus tipo 2. Método: ensayo clínico, aleatorizado, doble ciego, cruzado, multicéntrico y controlado. Se evaluó, a través de una escala del 1 al 4, el olor, el sabor y la textura percibida de un FED y de un FE. Resultados: se reclutaron a 29 pacientes y 58 evaluaciones sensoriales de los suplementos. Se observó una mejor valoración de la FED respecto a la FE, aunque no se alcanzaron diferencias estadísticamente significativas: olor, 0,04 (IC 95 %), de -0,49 a 0,56 (p = 0,092); sabor, 0,14 (IC 95 %), de -0,35 a 0,63 (p = 0,561); textura, 0,14, (IC 95 %), de -0,43 a 0,72 (p = 0,619). No se encontraron diferencias cuando se analizaron por orden de aleatorización, sexo, grado de desnutrición, mayor o menor grado de complejidad, mayor o menor tiempo de evolución de la diabetes, ni por ser más o menos mayores. Conclusiones: el suplemento nutricional específico para paciente con diabetes, formulado con aceite de oliva virgen extra, EPA y DHA, una mezcla específica en hidratos de carbono, fibra soluble e insoluble, presentó una adecuada aceptación sensorial del paciente desnutrido con diabetes mellitus tipo 2.

Clinical nutrition as part of the treatment pathway of pancreatic cancer patients: an expert consensus.

PURPOSE: Malnutrition is a common problem among pancreatic cancer (PC) patients that negatively impacts on their quality of life (QoL) and clinical outcomes. The main objective of this consensus is to address the role of Medical Nutrition Therapy (MNT) into the comprehensive therapeutic management of PC patients. METHODS: A Spanish multidisciplinary group of specialists from the areas of Medical Oncology; Radiation Oncology; Endocrinology and Nutrition; and General Surgery agreed to assess the role of MNT as part of the best therapeutic management of PC patients. RESULTS: The panel established different recommendations focused on nutritional screening and nutritional screening tools, MNT strategies according to PC status, and MNT in palliative treatment. CONCLUSIONS: There is an unmet need to integrate nutritional therapy as a crucial part of the multimodal care process in PC patients. Health authorities, health care professionals, cancer patients, and their families should be aware of the relevance of nutritional status and MNT on clinical outcomes and QoL of PC patients.

Nutrition Support Therapy.

Nutrition support therapy is the delivery of formulated enteral or parenteral nutrients to restore nutritional status. Family physicians can provide nutrition support therapy to patients at risk of malnutrition when it would improve quality of life. The evidence for when to use nutrition support therapy is inconsistent and based mostly on low-quality studies. Family physicians should work with registered dietitian nutritionists to complete a comprehensive nutritional assessment for patients with acute or chronic conditions that put them at risk of malnutrition. When nutrition support therapy is required, enteral nutrition is preferred for a patient with a functioning gastrointestinal tract, even in patients who are critically ill. Parenteral nutrition has an increased risk of complications and should be administered only when enteral nutrition is contraindicated. Family physicians can use the Mifflin-St Jeor equation to calculate the resting metabolic rate, and they should consult with a registered dietitian nutritionist to determine total energy needs and select a nutritional formula. Patients receiving nutrition support therapy should be monitored for complications, including refeeding syndrome. Nutrition support therapy does not improve quality of life in patients with dementia. Clinicians should engage in shared decision-making with patients and caregivers about nutrition support in palliative and end-of-life care.

Effect on an Oral Nutritional Supplement with ß-Hydroxy-ß-methylbutyrate and Vitamin D on Morphofunctional Aspects, Body Composition, and Phase Angle in Malnourished Patients.

This is a retrospective study of data from clinical practice to observe the effect of a high-calorie, high-protein oral nutritional supplement (ONS) with ß-hydroxy-ß-methylbutyrate (HMB) on nutritional status, body weight, and muscle-related parameters in 283 adult patients with or at risk of malnutrition under standard of care, 63% being cancer patients. They were recommended to increase physical activity and energy and protein intake from regular diet plus two servings per day of a specialized ONS enriched with HMB or standard ONS for up to 6 months. Dietary records, adherence and tolerance to ONS, nutritional status, body composition, handgrip strength, and blood analysis at the beginning and the end of the intervention were recorded. This program improved nutritional status from 100% malnourished or at risk of malnutrition at baseline to 80% well-nourished at final visit. It also increased body weight by 3.6-3.8 kg, fat-free mass by 0.9 to 1.3 kg, and handgrip strength by 4.7 to 6.2 kg. In a subgroup of patients (n = 43), phase angle (PhA), and body cell mass (BCM) increased only in the patients receiving the ONS enriched with HMB (0.95 (0.13) vs. -0.36 (0.4), and 2.98 (0.5) vs. -0.6 (1.5) kg, mean difference (SE) from baseline for PhA and BCM, respectively), suggesting the potential efficacy of this supplement on muscle health.

Phenotype assessment in neurologically impaired paediatric patients: Impact of a nutrition intervention protocol.

BACKGROUND: Deficits in nutritional status and functional feeding disorders are common in Neurologically Impaired Paediatric Patients (NIPP). Interventions addressing these problems could offer better overall health status and quality of life in this group of patients, but the extent of their effectiveness is yet to be determined. Recent guidelines concerning the nutritional care of NIPP have been published from ESPGHAN but compliance to them has not been assessed. AIM: The study aimed to assess the phenotypic profile of a group of NIPP attending the outpatient clinic of a pediatric department, and to implement, for the first time to our knowledge, an individualized nutritional intervention protocol following ESPGHAN guidelines 2017 as well as to assess the impact on phenotypic parameters and nutritional status. PATIENTS AND METHODS: 68NIPP and their caregivers aged 1m-17 years (83.8% suffering from cerebral palsy (CP) were invited to assess their phenotypic parameters and to implement in a nutrition intervention protocol in order to improve their dietary intake and nutritional status. Anthropometry (weight, height, triceps skinfold thickness, mid upper arm circumference) was expressed as z-scores for age and sex using WHO Anthro software and classified following the WHO criteria. Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), Dysphagia Disorder Survey (DDS), Saliva Severity Scale (SSS), gastrointestinal complications, energy and nutrient intake were assessed at the beginning (zero point), after 6 (point 1) and 12 (point 2) months period. Intake to Requirement ratio (I/R) was derived. At zero point, following the baseline evaluation, caregivers were advised and educated on nutrition protocol and customized nutrition plans were handed out. The impact of the nutritional intervention on the phenotypic parameters was recorded on follow up visits (points 1, 2).The primary outcomes analyzed were anthropometric parameters (Waz), as indicators of nutritional status. GMFCS, MACS, DDS, SSS, FA were evaluated as possible predictors of this outcome. Secondary outcomes included the impact of the intervention protocol on the phenotypic parameters during the study period. RESULTS: Based on weight for age z-score (Waz ≤ -2) (WHO) 17 patients (32.1%) were undernourished, 5/68 (10, 4%) were with triceps skinfold thickness z-score (TSTz) <-2 and 3/68 (7%) with mid upper arm circumference z-score (MUACz) <-2. Z-scores (WHO) for weight (p1 = 0, 036) (p2 = 0, 003), body mass index (BMI) (p2 = 0,000), MUAC (p1 = 0, 029) and TST (p1 = 0, 021) (p3 = 0, 044) were significantly improved in follow-up evaluations compared to the baseline. Less NIPP were found to be underweight according to Waz from point 1 to point 2 (p3 = 0, 006), as well as stunding according to height for age z-score (Haz) from point 1 to point 2 (p ≤ 0,001). Patients with higher levels of GMFCS (p1 = 0,040), MACS (p1 = 0,028) DDS (p1 = 0,001) and SSS (p1 = 0,005) had significantly lower Haz. Patients with higher levels of SSS (p1 = 0,002) had significantly lower TSTz scores. There were no significant changes in the classification of NIPP according to DDS or the patients' feeding ability. The energy (kcals) intake/kg of body weight (bw) was significantly higher at point 2 compared to point zero (p3 = 0,028), protein intake/kg of body weight was significantly higher at points 1 and 2 compared to point zero (p1 = 0,026, p3 = 0,003), and fat intake/kg of body weight (bw) was significantly higher at point 2 compared to point zero (p3 = 0,012). Intake of energy (kcals)/bw (p1 = 0,026), (p2 = 0,046), (p3 = 0,048) carbs/bw (p1 = 0,014) (p2 = 0,042), I/R of pro (p1 = 0,032), (p3 = 0,013), and fat/kg (p2 = 0, 033) (p3 = 0,037) were found to be significantly lower in higher GMFCS levels. DQI did not improve during the study period nor correlated to any of the anthropometric parameters. Gastrointestinal complications correlated with Waz (r = -, 285 p1 = 0, 011). Feeding Ability (FA) was found to be the only strong predictor for Waz at baseline evaluation (p = 0,012) when a multiple regression was run along with DDS. CONCLUSION: Underweight was detected in one third of the patients, some degree of dysphagia in 69% and gastrointestinal complications in 58.8% of the sample. Height for age z-score (Haz) was the anthropometric parameter most sensitive to the changes in ranking on motor and functional feeding scores. The implementation of a customized nutrition intervention protocol in line with ESPGHAN's guidelines had a beneficial effect on improving dietary intake and nutritional status of NIPP after a 12 months period. Better results could be expected if dysphagia and feeding ability were also addressed by appropriate intervention protocols. Patients' feeding ability is of importance for predicting Waz.
