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.

[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.

Management of disease-related malnutrition for patients being treated in hospital.

Disease-related malnutrition in adult patients who have been admitted to hospital is a syndrome associated with substantially increased morbidity, disability, short-term and long-term mortality, impaired recovery from illness, and cost of care. There is uncertainty regarding optimal diagnostic criteria, definitions for malnutrition, and how to identify patients who would benefit from nutritional intervention. Malnutrition has become the focus of research aimed at translating current knowledge of its pathophysiology into improved diagnosis and treatment. Researchers are particularly interested in developing nutritional interventions that reverse the negative effects of disease-related malnutrition in the hospital setting. High-quality randomised trials have provided evidence that nutritional therapy can reduce morbidity and other complications associated with malnutrition in some patients. Screening of patients for risk of malnutrition at hospital admission, followed by nutritional assessment and individualised nutritional interventions for malnourished patients, should become part of routine clinical care and multimodal treatment in hospitals worldwide.

Endoscopic gastrostomy for nutritional support in post-stroke dysphagia.

INTRODUCTION: Introduction: persistent dysphagia affects 15 % of stroke patients and contributes to malnutrition, aspiration, and death. This study aimed to characterize patients with post-stroke dysphagia who underwent percutaneous endoscopic gastrostomy (PEG), and to assess the impact of PEG feeding on nutritional status and outcome. Methods: an observational and retrospective study using records from patients with post-stroke dysphagia who underwent PEG. Body mass index (BMI), serum albumin, transferrin, and cholesterol were recorded at the time of PEG insertion (T0) and 3 months later (T3). The evolution of these parameters was analyzed and compared to survival. Results: we obtained data from 158 patients (53.2 % males) with a median age of 75 years. Most strokes were ischemic (n = 135, 85.4 %). Median time between stroke and PEG was 2 months. Median survival after gastrostomy was 16 months. At admission, 41.6 % of patients had low BMI, 62.3 % low albumin, 68.6 % low transferrin, and 59.6 % low cholesterol levels. The prevalence of low albumin and low transferrin was higher in the patients who underwent PEG more than 2 months after stroke. A significant increase in albumin and transferrin, and a normalization of cholesterol levels was observed after 3 months of PEG feeding. Mortality was 12.9 %, 27.7 %, and 40 % at 1, 3, and 12 months, respectively. Survival was lower in patients with low albumin, transferrin or total cholesterol at admission. Conclusions: the prevalence of malnutrition is high among patients with post-stroke dysphagia. PEG feeding improves albumin, transferrin, and cholesterol levels. Early post-PEG mortality is high and must be considered on an individual basis.

INTRODUCCIÓN: Introducción: la disfagia persistente afecta al 15 % de los pacientes con accidente cerebrovascular (AVC) y contribuye a producir desnutrición, aspiración y muerte. Este estudio tuvo como objetivo caracterizar a los pacientes con disfagia post-AVC sometidos a gastrostomía endoscópica percutánea (PEG) y evaluar el impacto de la alimentación con PEG sobre el estado nutricional. Métodos: estudio observacional y retrospectivo que utiliza registros de pacientes con disfagia post-AVC sometidos a PEG. El índice de masa corporal (IMC) y los niveles de albúmina, transferrina y colesterol séricos se registraron en el momento de la inserción de la PEG (T0) y 3 meses después (T3). La evolución de estos parámetros se analizó y comparó con la supervivencia. Resultados: se obtuvieron datos de 158 pacientes (53,2 % hombres) con una edad media de 75 años. La mayoría de los AVC fueron isquémicos (n = 135, 85,4 %). El tiempo medio entre el AVC y la PEG fue de 2 meses. La supervivencia media después de la gastrostomía fue de 16 meses. Al ingreso, el 41,6 % de los pacientes presentaba un IMC bajo, el 62,3 % un nivel bajo de albúmina, el 68,6 % un nivel bajo de transferrina y el 59,6 % un nivel bajo de colesterol. La prevalencia de los niveles bajos de albúmina y de transferrina fue mayor en los pacientes que se sometieron a la PEG más de 2 meses después del AVC. Se observó un aumento significativo de la albúmina y la transferrina, y una normalización de los niveles de colesterol, después de 3 meses de alimentación con PEG. La mortalidad fue del 12,9 %, 27,7 % y 40 % a 1, 3 y 12 meses, respectivamente. La supervivencia fue menor en los pacientes con nivel bajo de albúmina, transferrina o colesterol total al ingreso. Conclusiones: la prevalencia de la malnutrición es alta entre los pacientes con disfagia post-AVC. La alimentación con PEG mejora los niveles de albúmina, transferrina y colesterol. La mortalidad temprana post-PEG es alta y debe considerarse de forma individual.

A local-ingredients-based supplement is an alternative to corn-soy blends plus for treating moderate acute malnutrition among children aged 6 to 59 months: A randomized controlled non-inferiority trial in Wolaita, Southern Ethiopia.

BACKGROUND: Globally, moderate acute malnutrition (MAM) affects approximately 5% of children below five years of age. MAM is a persistent public health problem in Ethiopia. The current approach in Ethiopia for managing MAM is a supplementary feeding program; however, this is only provided to chronically food-insecure areas. The objective of the study was to compare a local-ingredients-based supplement (LIBS) with the standard corn-soy blend plus (CSB+) in treating MAM among children aged 6 to 59 months to test the hypothesis that the recovery rate achieved with LIBS will not be more than 7% worse than that achieved with CSB+. METHODS AND FINDINGS: We used an individual randomized controlled non-inferiority trial design with two arms, involving 324 children with MAM aged 6 to 59 months in Wolaita, Southern Ethiopia. One hundred and sixty-two children were randomly assigned to each of the two arms. In the first arm, 125.2 g of LIBS with 8 ml of refined deodorized and cholesterol-free sunflower oil/day was provided. In the second arm, 150 g of CSB+ with 16 ml of refined deodorized and cholesterol-free sunflower oil/day was provided. Each child was provided with a daily ration of either LIBS or CSB+ for 12 weeks. Both intention-to-treat (ITT) and per-protocol (PP) analyses were done. ITT and PP analyses showed non-inferiority of LIBS compared with CSB+ for recovery rate [ITT risk difference = 4.9% (95% CI: -4.70, 14.50); PP risk difference = 3.7% (95% CI: -5.91, 13.31)]; average weight gain [ITT risk difference = 0.10 g (95% CI: -0.33 g, 0.53 g); PP risk difference = 0.04 g (95% CI: -0.38 g, 0.47 g)]; and recovery time [ITT risk difference = -2.64 days (95% CI: -8.40 days, 3.13 days); PP difference -2.17 days (95% CI: -7.97 days, 3.64 days]. Non-inferiority in MUAC gain and length/height gain was also observed in the LIBS group compared with the CSB+ group. CONCLUSIONS: LIBS can be used as an alternative to the standard CSB+ for the treatment of MAM. Thus, the potential of scaling up the use of LIBS should be promoted.

Nutrition and Frailty: Opportunities for Prevention and Treatment.

Frailty is a syndrome of growing importance given the global ageing population. While frailty is a multifactorial process, poor nutritional status is considered a key contributor to its pathophysiology. As nutrition is a modifiable risk factor for frailty, strategies to prevent and treat frailty should consider dietary change. Observational evidence linking nutrition with frailty appears most robust for dietary quality: for example, dietary patterns such as the Mediterranean diet appear to be protective. In addition, research on specific foods, such as a higher consumption of fruit and vegetables and lower consumption of ultra-processed foods are consistent, with healthier profiles linked to lower frailty risk. Few dietary intervention studies have been conducted to date, although a growing number of trials that combine supplementation with exercise training suggest a multi-domain approach may be more effective. This review is based on an interdisciplinary workshop, held in November 2020, and synthesises current understanding of dietary influences on frailty, focusing on opportunities for prevention and treatment. Longer term prospective studies and well-designed trials are needed to determine the causal effects of nutrition on frailty risk and progression and how dietary change can be used to prevent and/or treat frailty in the future.

Nutritional Approach to Prevention and Treatment of Cardiovascular Disease in Childhood.

Coronary Heart Disease (CHD) is a major mortality and morbidity cause in adulthood worldwide. The atherosclerotic process starts even before birth, progresses through childhood and, if not stopped, eventually leads to CHD. Therefore, it is important to start prevention from the earliest stages of life. CHD prevention can be performed at different interventional stages: primordial prevention is aimed at preventing risk factors, primary prevention is aimed at early identification and treatment of risk factors, secondary prevention is aimed at reducing the risk of further events in those patients who have already experienced a CHD event. In this context, CHD risk stratification is of utmost importance, in order to tailor the preventive and therapeutic approach. Nutritional intervention is the milestone treatment in pediatric patients at increased CHD risk. According to the Developmental Origin of Health and Disease theory, the origins of lifestyle-related disease is formed in the so called "first thousand days" from conception, when an insult, either positive or negative, can cause life-lasting consequences. Nutrition is a positive epigenetic factor: an adequate nutritional intervention in a developmental critical period can change the outcome from childhood into adulthood.

Zinc Biofortification in Food Crops Could Alleviate the Zinc Malnutrition in Human Health.

Micronutrient malnutrition is a global health issue and needs immediate attention. Over two billion people across the globe suffer from micronutrient malnutrition. The widespread zinc (Zn) deficiency in soils, poor zinc intake by humans in their diet, low bioavailability, and health consequences has led the research community to think of an economic as well as sustainable strategy for the alleviation of zinc deficiency. Strategies like fortification and diet supplements, though effective, are not economical and most people in low-income countries cannot afford them, and they are the most vulnerable to Zn deficiency. In this regard, the biofortification of staple food crops with Zn has been considered a useful strategy. An agronomic biofortification approach that uses crop fertilization with Zn-based fertilizers at the appropriate time to ensure grain Zn enrichment has been found to be cost-effective, easy to practice, and efficient. Genetic biofortification, though time-consuming, is also highly effective. Moreover, a Zn-rich genotype once developed can also be used for many years without any recurring cost. Hence, both agronomic and genetic biofortification can be a very useful tool in alleviating Zn deficiency.

Identifying Low Value Malnutrition Care Activities for De-Implementation and Systematised, Interdisciplinary Alternatives-A Multi-Site, Nominal Group Technique Approach.

Malnutrition risk is identified in over one-third of inpatients; reliance on dietetics-delivered nutrition care for all "at-risk" patients is unsustainable, inefficient, and ineffective. This study aimed to identify and prioritise low-value malnutrition care activities for de-implementation and articulate systematised interdisciplinary opportunities. Nine workshops, at eight purposively sampled hospitals, were undertaken using the nominal group technique. Participants were asked "What highly individualised malnutrition care activities do you think we could replace with systematised, interdisciplinary malnutrition care?" and "What systematised, interdisciplinary opportunities do you think we should do to provide more effective and efficient nutrition care in our ward/hospital?" Sixty-three participants were provided five votes per question. The most voted de-implementation activities were low-value nutrition reviews (32); education by dietitian (28); assessments by dietitian for patients with malnutrition screening tool score of two (22); assistants duplicating malnutrition screening (19); and comprehensive, individualised nutrition assessments where unlikely to add value (15). The top voted alternative opportunities were delegated/skill shared interventions (55), delegated/skill shared education (24), abbreviated malnutrition care processes where clinically appropriate (23), delegated/skill shared supportive food/fluids (14), and mealtime assistance (13). Findings highlight opportunities to de-implement perceived low-value malnutrition care activities and replace them with systems and skill shared alternatives across hospital settings.

Vitamin D supplementation prior to or during COVID-19 associated with better 3-month survival in geriatric patients: Extension phase of the GERIA-COVID study.

BACKGROUND: The objective of this extension phase of the quasi-experimental GERIA-COVID study was to determine whether vitamin D3 supplementation taken prior to or during COVID-19 was associated with better 3-month survival in geriatric patients hospitalized for COVID-19. METHODS: Intervention group was defined as all participants supplemented with vitamin D3 prior to or during COVID-19 (n = 67). Supplements were either bolus vitamin D3 (ie, 50,000 IU per month, or 80,000 IU or 100,000 IU or 200,000 IU every 2-3 months), or daily supplementation with 800 IU. Comparator group involved those without vitamin D supplements (n = 28). Outcome was 3-month mortality. Covariables were age, sex, functional abilities, history of malignancies, cardiomyopathy, undernutrition, number of acute health issues, antibiotics use, systemic corticosteroids use, and 25(OH)D concentration. RESULTS: 76.1 % (n = 51) of participants survived at 3 months in Intervention group, compared to only 53.6 % (n = 15) in Comparator group (P = 0.03). The fully-adjusted hazard ratio for 3-month mortality was HR = 0.23 [95 %CI: 0.09;0.58](P = 0.002) in Intervention group compared to Comparator group. Intervention group had also longer survival time (log-rank P = 0.008). CONCLUSIONS: Vitamin D3 supplementation was associated with better 3-month survival in older COVID-19 patients.

The effect of oral omega-3 polyunsaturated fatty acid supplementation on muscle maintenance and quality of life in patients with cancer: A systematic review and meta-analysis.

BACKGROUND & AIMS: Omega-3 polyunsaturated fatty acid (PUFA) supplementation has been proposed as a potential therapy for cancer-related malnutrition, which affects up to 70% of patients with cancer. The aim of this systematic review and meta-analysis was to examine the effects of oral omega-3 PUFA supplementation on muscle maintenance, quality of life, body weight and treatment-related toxicities in patients with cancer. METHODS: Randomised controlled trials in patients with cancer aged ≥18 years were retrieved from 5 electronic databases: MEDLINE (via PubMed), EMBASE, CENTRAL, CINAHL (via EBSCOhost), and Web of Science, from database inception until 31st of December 2019. The quality of included studies was assessed using the Cochrane risk of bias tool. Trials supplementing ≥600 mg/d omega-3 PUFA (oral capsules, pure fish oil or oral nutritional supplements) compared with a control intervention for ≥3 weeks were included. Meta-analyses were performed in RevMan to determine the mean differences (MD) in muscle mass, quality of life and body weight, and odds ratio (OR) for the incidence of treatment-related toxicities between omega-3 PUFA and control groups with 95% confidence intervals (CI) and I2 for heterogeneity. RESULTS: We included 31 publications in patients with various types of cancers and degrees of malnutrition. The Cochrane risk of bias tool graded most trials as 'unclear' or 'high' risk of bias. Meta-analyses showed no significant difference between omega-3 PUFA supplements and control intervention on muscle mass, quality of life and body weight. Oral omega-3 PUFA supplements reduced the likelihood of developing chemotherapy-induced peripheral neuropathy (OR: 0.20; 95% CI: 0.10-0.40; p < 0.001; I2 = 0%). CONCLUSION: This systematic review and meta-analysis indicates that oral omega-3 PUFA supplementation does not improve muscle maintenance, quality of life or body weight in patients with cancer, but may reduce the incidence of chemotherapy-induced peripheral neuropathy. Well-designed large-scale randomised controlled trials in homogenous patient cohorts are required to confirm these findings.

Diet and Exercise Interventions in Patients With Pancreatic Cancer: A Scoping Review.

ABSTRACT: Diet and exercise interventions may help reverse malnutrition and muscle wasting common in pancreatic cancer. We performed a scoping review to identify the knowledge gaps surrounding diet and exercise interventions. We searched PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature, Embase, ProQuest Theses and Dissertations, and Google Scholar using the umbrella terms of "pancreatic cancer," "diet/nutrition," and "exercise." Included were articles reporting on ambulatory adults with diagnosed pancreatic cancer. Excluded were studies examining prevention and/or risk, animal, or cell lines. Of the 15,708 articles identified, only 62 met the final inclusion criteria. Almost half of the articles were randomized controlled studies (n = 27). Most studies were from the United States (n = 20). The majority examined dietary interventions (n = 41), with 20 assessing the use of omega-3 fatty acids. Exercise interventions were reported in 13 studies, with 8 examining a diet and exercise intervention. Most studies were small and varied greatly in terms of study design, intervention, and outcomes. We identified 7 research gaps that should be addressed in future studies. This scoping review highlights the limited research examining the effect of diet and exercise interventions in ambulatory patients with pancreatic cancer.

GLOBAL ENDOCRINOLOGY: Global perspectives in endocrinology: coverage of iodized salt programs and iodine status in 2020.

Iodine deficiency has multiple adverse effects on growth and development. Diets in many countries cannot provide adequate iodine without iodine fortification of salt. In 2020, 124 countries have legislation for mandatory salt iodization and 21 have legislation allowing voluntary iodization. As a result, 88% of the global population uses iodized salt. For population surveys, the urinary iodine concentration (UIC) should be measured and expressed as the median, in µg/L. The quality of available survey data is high: UIC surveys have been done in 152 out of 194 countries in the past 15 years; in 132 countries, the studies were nationally representative. The number of countries with adequate iodine intake has nearly doubled from 67 in 2003 to 118 in 2020. However, 21 countries remain deficient, while 13 countries have excessive intakes, either due to excess groundwater iodine, or over-iodized salt. Iodine programs are reaching the poorest of the poor: of the 15 poorest countries in the world, 10 are iodine sufficient and only 3 (Burundi, Mozambique and Madagascar) remain mild-to-moderately deficient. Nigeria and India have unstable food systems and millions of malnourished children, but both are iodine-sufficient and population coverage with iodized salt is a remarkable 93% in both. Once entrenched, iodine programs are often surprisingly durable even during national crises, for example, war-torn Afghanistan and Yemen are iodine-sufficient. However, the equity of iodized salt programs within countries remains an important issue. In summary, continued support of iodine programs is needed to sustain these remarkable global achievements, and to reach the remaining iodine-deficient countries.

A Microbiota-Directed Food Intervention for Undernourished Children.

BACKGROUND: More than 30 million children worldwide have moderate acute malnutrition. Current treatments have limited effectiveness, and much remains unknown about the pathogenesis of this condition. Children with moderate acute malnutrition have perturbed development of their gut microbiota. METHODS: In this study, we provided a microbiota-directed complementary food prototype (MDCF-2) or a ready-to-use supplementary food (RUSF) to 123 slum-dwelling Bangladeshi children with moderate acute malnutrition between the ages of 12 months and 18 months. The supplementation was given twice daily for 3 months, followed by 1 month of monitoring. We obtained weight-for-length, weight-for-age, and length-for-age z scores and mid-upper-arm circumference values at baseline and every 2 weeks during the intervention period and at 4 months. We compared the rate of change of these related phenotypes between baseline and 3 months and between baseline and 4 months. We also measured levels of 4977 proteins in plasma and 209 bacterial taxa in fecal samples. RESULTS: A total of 118 children (59 in each study group) completed the intervention. The rates of change in the weight-for-length and weight-for-age z scores are consistent with a benefit of MDCF-2 on growth over the course of the study, including the 1-month follow-up. Receipt of MDCF-2 was linked to the magnitude of change in levels of 70 plasma proteins and of 21 associated bacterial taxa that were positively correlated with the weight-for-length z score (P<0.001 for comparisons of both protein and bacterial taxa). These proteins included mediators of bone growth and neurodevelopment. CONCLUSIONS: These findings provide support for MDCF-2 as a dietary supplement for young children with moderate acute malnutrition and provide insight into mechanisms by which this targeted manipulation of microbiota components may be linked to growth.

[Analysis of nutritional interventions in the care process of oncological patients in Andalusia - The NOA project]. / Análisis de las intervenciones nutricionales en el proceso asistencial del paciente oncológico en Andalucía: el proyecto NOA.

INTRODUCTION: Introduction: malnutrition in cancer patients can lead to a reduction in patient quality of life, increased morbidity and mortality, and associated healthcare costs. Objective: to analyze nutritional interventions in the different phases of the oncological process, integrating the needs of patients and those of healthcare professionals. Material and methods: "Design Thinking" techniques were used to address the analysis of the current situation and identify key aspects. Thirteen professionals from 8 public health centers (endocrinology and nutrition, medical and radiotherapy oncology, primary care (PC), nursing and dietetics) participated in the study. Results: nutritional screening is not carried out in a systematic way in the different phases of the oncological process, and there is no universal consensus on the protocols for action and nutritional intervention. A wide compliance with the pathways and referral times of the selected processes has been observed. In the therapeutic phase, there is the possibility of consulting the Clinical Nutrition and Dietetics Unit (UNCYD) and 75 % have specific referral protocols. The nurse case manager is present in all hospitals and in PC. Patient access to the center psychologist was possible in 87 % of the hospitals. Participation of the UNCYD in Tumor Committees was low (only in 25 % of the centers). In all centers there is some kind of collaboration and support by patient associations and the School of Patients, especially in the therapeutic and the control and follow-up phases. Conclusions: variations are observed between the different hospitals and areas in Andalusia, both in terms of means and structures and in activities and procedures. Key points have been selected and prioritized to improve nutritional care in oncology.

INTRODUCCIÓN: Introducción: la desnutrición en los pacientes oncológicos puede conllevar una reducción de la calidad de vida del paciente y un aumento de la morbimortalidad y de los costes sanitarios asociados. Objetivos: analizar las intervenciones nutricionales en las diferentes fases del proceso oncológico, integrando las necesidades de los pacientes y las de los profesionales sanitarios. Material y métodos: se utilizaron técnicas de Design Thinking para abordar el análisis de la situación actual e identificar los aspectos clave. Participaron 13 profesionales de 8 centros sanitarios (endocrinología y nutrición, oncología médica y radioterápica, atención primaria (AP), enfermería y dietética) públicos de Andalucía. Resultados: no se realiza cribado nutricional de forma sistemática en las diferentes fases del proceso oncológico, y no existe consenso universal en los protocolos de actuación e intervención nutricional. Existe un cumplimiento generalizado de los circuitos y tiempos de derivación de los procesos seleccionados. En la fase terapéutica se dispone de la posibilidad de consultar a la Unidad de Nutrición Clínica y Dietética (UNCYD) y el 75 % disponen de protocolos específicos de derivación. La enfermera gestora de casos está presente en todos los hospitales y en AP. El acceso del paciente al psicólogo del centro era posible en el 87 % de los hospitales. Escasa participación de la UNCYD en los Comités de Tumores (solo en el 25 % de los centros). En todos los centros existe algún tipo de colaboración y apoyo de las asociaciones de pacientes y de la Escuela de Pacientes, especialmente en las fases terapéuticas y de control y seguimiento. Conclusiones: se observan variaciones entre los diferentes hospitales y territorios de Andalucía, tanto en la disposición de medios y estructuras como en las actividades y procedimientos. Se han seleccionado y priorizado puntos clave para mejorar la atención nutricional en oncología.
