RESUMO

The aim of this study was to evaluate the accuracy of nutrient intake assessment with the food group-based algorithm "Calculator of Inadequate Micronutrient Intake" (CIMI) in comparison to the established nutrition software NutriSurvey. Using Food Frequency Questionnaires and 24-h dietary recalls of 1010 women from two rural districts in Tanzania, 23 relevant typical Tanzanian food groups were identified and subsequently the dietary protocols assessed via CIMI algorithm were compared by bivariate correlations and Bland-Altman analysis with the results of the NutriSurvey software (reference) and were set in relation to blood biomarkers of 666 participants. CIMI and NutriSurvey calculations regarding macro- and micronutrient intakes were similar. The Bland-Altman analyses and correlation coefficients of energy (0.931), protein (0.898), iron (0.775) and zinc (0.838) confirm the agreement of both calculations. The food group based CIMI algorithm is a practical tool to identify the inadequacy of macro- and micronutrient intake at population level.

RESUMO

Sex differences are an important consideration when researching and establishing policies for nutrition and optimal health. For women's health, there are important physiologic, neurologic, and hormonal distinctions throughout the lifecycle that impact nutritional needs. Distinct from those for men, these nutritional needs must be translated into appropriate nutrition policy that aims to not only avoid overt nutritional deficiency, but also to promote health and minimize risk for chronic disease. Through a series of webinars, scientific experts discussed the advances in the understanding of the unique nutritional needs, challenges and opportunities of the various life stages for women across the life course and identified emerging nutritional interventions that may be beneficial for women. Nevertheless, there is concern that existing nutrition policy intended for women's health is falling short with examples of programs that are focused more on delivering calories than achieving optimal nutrition. To be locally effective, targeted nutrition needs to offer different proposals for different cultural, socio-economic, and geographic communities, and needs to be applicable at all stages of growth and development. There must be adequate access to nutritious foods, and the information to understand and implement proven nutritional opportunities. Experts provided recommendations for improvement of current entitlement programs that will address accessibility and other social and environmental issues to support women properly throughout the lifecycle.

RESUMO

BACKGROUND: Depression during pregnancy has far-reaching adverse consequences on mothers, children and the whole family. The magnitude and determinants of prenatal depressive symptoms in low-resource countries are not well established. This study aims to describe the prevalence of prenatal depressive symptoms and whether it is associated with maternal nutrition, intimate partner violence and social support among pregnant women in rural Ethiopia. METHODS: This study is based on the baseline data from a large prospective, community-based, birth cohort study conducted in the South Western part of Ethiopia from March 2014 to March 2016. A total of 4680 pregnant women were recruited between 12 and 32 weeks of gestation. Depressed mood was assessed using the Patient Health Questionnaire (PHQ-9) scale and a cut off of ≥8 was taken to define prenatal depressive symptoms. Data collection was conducted electronically on handheld tablets and submitted to a secured server via an internet connection. Bivariate and multivariate logistic regression analyses were computed using IBM SPSS version 20 software. RESULT: The community based prevalence of depressive symptoms during pregnancy was 10.8% (95%Confidence Interval (CI): 9.92-11.70). Adjusting for confounding variables, moderate household food insecurity (OR 1.74; 95% CI: 1.31-2.32), severe household food insecurity (OR 7.90; 95% CI: 5.87-10.62), anaemia (OR = 1.30; 95% CI: 1.04-1.61) and intimate partner violence (OR 3.08; 95% CI: 2.23-4.25) were significantly associated with prenatal depressive symptoms. On the other hand, good social support from friends, families and husband reduced the risk of prenatal depressive symptoms by 39% (OR 0.61; 95% CI: 0.50-0.76). CONCLUSION: Prenatal depressive symptomatology is rather common during pregnancy in rural Ethiopia. In this community based study, household food insecurity, anaemia and intimate partner violence were significantly associated with prenatal depressive symptoms. Good maternal social support from friends, families and spouse was rather protective. The study highlights the need for targeted screening for depression and intimate partner violence during pregnancy. Policies aimed at reducing household food insecurity, maternal anaemia and intimate partner violence during pregnancy may possibly reduce depression.

RESUMO

BACKGROUND: Trace elements and vitamins, named together micronutrients (MNs), are essential for human metabolism. The importance of MNs in common pathologies is recognized by recent research, with deficiencies significantly impacting the outcome. OBJECTIVE: This short version of the guideline aims to provide practical recommendations for clinical practice. METHODS: An extensive search of the literature was conducted in the databases Medline, PubMed, Cochrane, Google Scholar, and CINAHL for the initial guideline. The search focused on physiological data, historical evidence (for papers published before PubMed release in 1996), and observational and/or randomized trials. For each MN, the main functions, optimal analytical methods, impact of inflammation, potential toxicity, and provision during enteral or parenteral nutrition were addressed. The SOP wording was applied for strength of recommendations. RESULTS: The limited number of interventional trials prevented meta-analysis and led to a low level of evidence for most recommendations. The recommendations underwent a consensus process, which resulted in a percentage of agreement (%): strong consensus required of >90 % of votes. Altogether the guideline proposes 3 general recommendations and specific recommendations for the 26 MNs. Monitoring and management strategies are proposed. CONCLUSION: This short version of the MN guideline should facilitate handling of the MNs in at-risk diseases, whilst offering practical advice on MN provision and monitoring during nutritional support.

RESUMO

BACKGROUND: Vitamin A plays a key role in lung development, but there is no consensus regarding the optimal vitamin A dose and administration route in extremely low birthweight (ELBW) infants. We aimed to assess whether early postnatal additional high-dose fat-soluble enteral vitamin A supplementation versus placebo would lower the rate of moderate or severe bronchopulmonary dysplasia or death in ELBW infants receiving recommended basic enteral vitamin A supplementation. METHODS: This prospective, multicentre, randomised, parallel-group, double-blind, placebo-controlled, investigator-initiated phase 3 trial conducted at 29 neonatal intensive care units in Austria and Germany assessed early high-dose enteral vitamin A supplementation (5000 international units [IU]/kg per day) or placebo (peanut oil) for 28 days in ELBW infants. Eligible infants had a birthweight of more than 400 g and less than 1000 g; gestational age at birth of 32+0 weeks postmenstrual age or younger; and the need for mechanical ventilation, non-invasive respiratory support, or supplemental oxygen within the first 72 h of postnatal age after admission to the neonatal intensive care unit. Participants were randomly assigned by block randomisation with variable block sizes (two and four). All participants received basic vitamin A supplementation (1000 IU/kg per day). The composite primary endpoint was moderate or severe bronchopulmonary dysplasia or death at 36 weeks postmenstrual age, analysed in the intention-to-treat population. This trial was registered with EudraCT, 2013-001998-24. FINDINGS: Between March 2, 2015, and Feb 27, 2022, 3066 infants were screened for eligibility at the participating centres. 915 infants were included and randomly assigned to the high-dose vitamin A group (n=449) or the control group (n=466). Mean gestational age was 26·5 weeks (SD 2·0) and mean birthweight was 765 g (162). Moderate or severe bronchopulmonary dysplasia or death occurred in 171 (38%) of 449 infants in the high-dose vitamin A group versus 178 (38%) of 466 infants in the control group (adjusted odds ratio 0·99, 95% CI 0·73-1·55). The number of participants with at least one adverse event was similar between groups (256 [57%] of 449 in the high-dose vitamin A group and 281 [60%] of 466 in the control group). Serum retinol concentrations at baseline, at the end of intervention, and at 36 weeks postmenstrual age were similar in the two groups. INTERPRETATION: Early postnatal high-dose fat-soluble enteral vitamin A supplementation in ELBW infants was safe, but did not change the rate of moderate or severe bronchopulmonary dysplasia or death and did not substantially increase serum retinol concentrations.

RESUMO

Beside many risk factors in patients considered for alloHCT, only body mass index (BMI) as a broad marker of nutritional status has prognostic value in these patients. This is the first prospective study to investigate the validity of further nutritional markers: adjusted BMI, normalized for gender and age; Subjective Global Assessment questionnaire and standardized phase angle, normalized for gender, age and BMI in 105 patients as independent risk factors for outcomes [overall survival (OS), non-relapse mortality (NRM), relapse mortality (RM), progression-free survival (PFS)] until 2 years after alloHCT. In Cox proportional-hazards regression models, we included a variety of accepted risk factors. The two most influential pre-transplant risk factors identified and associated with similarly increased hazard ratios (HR) for OS, RM, and PFS were a low-standardized phase angle (HR = 1.97, P = 0.043; HR = 3.18, P = 0.017, and HR = 1.91, P = 0.039) and advanced disease. Under- and overweight according BMI percentiles (≤10th; ≥90th) revealed associations with increased risk of NRM (HR = 2.90, P = 0.018; HR = 3.02, P = 0.062), although only low BMI was weakly associated with OS (HR = 1.82, P = 0.09). In conclusion, our results demonstrate that pre-transplant phase angle is an independent predictor for 2-year outcomes in these patients. Further investigation is necessary to demonstrate whether the theoretically modifiable phase angle can be increased by physical training combined with nutritional support, and if this improves outcome after alloHCT.

RESUMO

Nutrients can be classified as either "essential" or "non-essential," the latter are also termed bioactive substances. Whereas the absence of essential nutrients from the diet results in overt deficiency often times with moderate to severe physiological decrements, the absence of bioactive substances from the diet results in suboptimal health. Nutrient reference values are set by Codex Alimentarius and regulatory bodies in many countries, mostly for essential nutrients with recommended daily intakes. The IOM in the United States has defined a set of four DRIs that, when data are appropriate, include an EAR, a RDA that is derived from the EAR, an AI for nutrients without appropriate data to identify an EAR, and an UL. From the RDA, the United States derives a labeling value called the DV, which applies to older children and most adults. In Codex, the equivalents of the DVs are the NRVs to be used in calculating percentage values on food labels. Nothing in the IOM documents specifies that labeling values can be set only for what have been defined to date as essential nutrients. Indeed, the US Food and Drug Administration sets a labeling value for dietary fiber based on the IOM AI for this ingredient. This conference explores the definitions, concepts, and data on two of the best examples of bioactive substances that, perhaps, should have NRVs: lutein and zeaxanthin, and n-3 long-chain polyunsaturated fatty acids.

RESUMO

Hypovitaminosis D (<30 ng/ml) is highly prevalent in allogeneic hematopoietic cell transplantation (alloHCT), but the relevance of influencing factors for serum 25-hydroxyvitamin D(3) [25(OH)D(3)] status in adult patients remains unknown. We are the first to have prospectively assessed 25(OH)D(3) status and its influencing factors in 102 patients before and at days +30 and +100 after alloHCT. Among others, we evaluated age, gender, weight, fat mass, season, sun exposure habits, and dietary and supplemental vitamin D intake as factors potentially influencing baseline vitamin D status in uni- and multivariate linear regression analysis. Furthermore, we investigated the impact of changes in fat mass, duration of parenteral nutrition, and acute graft-versus-host disease (aGVHD) on the course of serum 25(OH)D(3). Baseline 25(OH)D(3) concentrations were 16.4 ± 8.9 ng/ml, revealing that the majority (89%) had concentrations beneath the normal range. In multivariate linear regression model, only higher body fat mass remained an independent risk factor for reduced baseline 25(OH)D(3) concentrations (P = 0.007). In the early post-transplant period, 25(OH)D(3) status remained low, revealing a tendency to further deterioration, especially in patients with corticosteroid-treated aGVHD (≥II). Reduced vitamin D status was very common in these patients before and after alloHCT, whereby the most important influencing factors, namely season and dietary factors seem to have little impact. Our findings suggest that monitoring and if necessary, correcting vitamin D status may be indicated at regular intervals before alloHCT and during long-term follow-up. Further investigations of these patients' vitamin D requirements are needed, especially if they are on long-term corticosteroids.

RESUMO

BACKGROUND: Deficiency of micronutrients is common in refugee populations. OBJECTIVES: Identify deficiencies and whether provided supplements and wheat flour fortified with 10 micronutrients impacts upon status among breast-feeding women from Maela refugee camp. METHODS: Two sequential cross-sectional studies were conducted in different groups of lactating mothers at 12 weeks postpartum. The first survey was before and the second 4-5 months after micronutrient fortified flour (MFF) had been provided to the camp (in addition to the regular food basket). Iron status and micronutrients were measured in serum, whole blood, and in breast milk samples. RESULTS: Iron and zinc deficiency and anemia were highly prevalent while low serum retinol and thiamine deficiency were rarely detected. Iron and zinc deficiency were associated with anemia, and their proportions were significantly lower after the introduction of MFF (21 vs. 35% with soluble transferrin receptor (sTfR) >8.5 mg/L, P = 0.042, and 50 vs. 73% with serum zinc <0.66 mg/L, P = 0.001). Serum sTfR, whole-blood thiamine diphosphate (TDP) and serum ß-carotene were significant predictors (P < 0.001) of milk iron, thiamine and ß-carotene, respectively. Lower prevalence of iron deficiency in the MFF group was associated with significantly higher iron and thiamine in breast milk. CONCLUSIONS: High whole-blood TDP and breast milk thiamine reflected good compliance to provided thiamine; high prevalence of iron deficiency suggested insufficient dietary iron and low acceptance to ferrous sulfate supplements. MFF as an additional food ration in Maela refugee camp seemed to have an effect in reducing both iron and zinc deficiency postpartum.

RESUMO

PURPOSE: Oral mucositis (OM) is known to be a significant complication of chemotherapy preceding haematopoietic cell transplantation (HCT). Antioxidants (AOX) scavenge free radicals, which play a major role in the initiation of OM and may reduce the OM risk. STUDY DESIGN: The primary objective of this prospective study was to investigate the association between the incidence and severity of OM (WHO oral toxicity scale) and the AOX status in buccal mucosa cells (BMC) and plasma. The α-tocopherol, ascorbic acid and ß-carotene concentrations in BMC and plasma were assessed at admission in 70 patients with a median age of 58 years before undergoing allogeneic HCT. RESULTS: Severe OM (III-IV), ulcerative OM (II-IV) and no or mild OM (0-I) were documented in 14 (20.0%), 32 (45.7%) and 38 (54.3%) patients, respectively. We observed no significant differences in baseline AOX concentrations in plasma or BMC among the OM groups. However, between patients with at least one plasma AOX beneath the normal range (39/70) and those with all plasma AOX in the normal range (31/70), we noted a trend towards longer duration of parenteral nutrition (PN) during the study period (10 vs. 8 days; p = 0.066). CONCLUSIONS: No single AOX, either in plasma or BMC (α-tocopherol, ascorbic acid and ß-carotene), revealed predictive value for the incidence or severity of OM. However, patients with an overall good plasma AOX status tended to require less PN, a common clinical marker for OM, which may be more relevant than any one AOX at reducing the risk of OM.

RESUMO

OBJECTIVE: The present research aimed to analyse the nutrient density (ND), nutrient adequacy score (NAS) and energy density (ED) of Indonesian foods and to formulate a balanced diet using linear programming. DESIGN: Data on typical Indonesian diets were obtained from the Indonesian Socio-Economic Survey 2008. ND was investigated for 122 Indonesian foods. NAS was calculated for single nutrients such as Fe, Zn and vitamin A. Correlation analysis was performed between ND and ED, as well as between monthly expenditure class and food consumption pattern in Indonesia. Linear programming calculations were performed using the software POM-QM for Windows version 3. SETTING: Republic of Indonesia, 2008. SUBJECTS: Public households (n 68 800). RESULTS: Vegetables had the highest ND of the food groups, followed by animal-based foods, fruits and staple foods. Based on NAS, the top ten food items for each food group were identified. Most of the staple foods had high ED and contributed towards daily energy fulfillment, followed by animal-based foods, vegetables and fruits. Commodities with high ND tended to have low ED. Linear programming could be used to formulate a balanced diet. In contrast to staple foods, purchases of fruit, vegetables and animal-based foods increased with the rise of monthly expenditure. CONCLUSIONS: People should select food items based on ND and NAS to alleviate micronutrient deficiencies in Indonesia. Dietary formulation calculated using linear programming to achieve RDA levels for micronutrients could be recommended for different age groups of the Indonesian population.

RESUMO

BACKGROUND: Food-based approaches have been advocated as the best strategies to curb hunger and malnutrition in developing countries. The use of low-cost, locally available, nutritious foods in the development of supplementary foods has been recommended. OBJECTIVE: To develop low-cost food supplements using different traditionally processed local foods, consisting of cereals, legumes, nuts, fish, and vegetables, to meet the nutrient requirements for vulnerable groups in Kenya. METHODS: Four food supplements were developed and evaluated by taste panel procedures. The product containing amaranth grain, pigeon pea, sweet potato, groundnuts, and brown sugar was found to be the most acceptable supplement. Evaluation of nutritional composition, shelf-life, and cost analysis of the acceptable supplement was carried out to assess if it could satisfactorily provide more than 50% of the Recommended Dietary Allowances (RDAs) of the basic nutrients for vulnerable groups. RESULTS: The acceptable supplement contained 453.2 kcal energy, 12.7 g crude protein, 54.3 g soluble carbohydrates, 20.8 g crude fat, and 10.1 g crude fiber per 110 g. The micronutrient contents were 93.0 mg calcium, 172.4 mg magnesium, 2.7 mg zinc, 5.7 mg iron, 0.8 mg vitamin B1, 0.2 mg vitamin B2, 7.9 mg niacin, 100 microg folic acid, and 140 microg retinol equivalent per 110 g. The supplement also contained 21% total essential amino acid in addition to appreciable levels of palmitic, stearic, oleic, linoleic, and alpha-linolenic fatty acids. The shelf-life study showed that it could be stored in different packaging materials (polythene bags, gunny bags, and kraft paper) at 26°C without deleterious effects on its chemical composition for up to 4 months. Cost analysis of the supplement indicated that the product could be competitively sold at US$0.812/kg (KES 65.50/kg). CONCLUSIONS: Locally available indigenous foods can be used in the formulation of acceptable, low-cost, shelf-stable, nutritious supplementary foods for vulnerable groups.

RESUMO

BACKGROUND: Ready-to-use food in the form of biscuits (RUF-Nias biscuit) was locally produced for rehabilitation of moderately and mildly wasted (weight-for-height z-score > or = -3 to < -1.5 SD) children on Nias Island, Indonesia. Daily programs were performed in semiurban settings, and weekly programs took place in rural areas. OBJECTIVE: To analyze the cost of daily and weekly distribution and supervision of RUF-Nias biscuit programs. METHODS: The costs of the daily and weekly programs were derived from the financial report and interviews with program implementers and participating households. Costs were calculated on the basis of total rehabilitation costs per child per day required to achieve a target weight-for-height z-score > or = -1.5 SD in daily and weekly programs. RESULTS: Institutional costs to the implementing organization were similar for both programs (approximately US $4 per child per day). The daily programs resulted in a significantly higher proportion of recovered children (78.6% vs. 65.4%) and higher weight gain (3.7 vs. 2.2 g/kg/day) than the weekly programs. About 6% to 7% of the total cost of the programs was accounted for by locally produced RUF-Nias biscuits. The social cost borne by the community for the weekly programs was about half that for the daily programs. CONCLUSIONS: The daily programs achieved better results for the implementing organization than the weekly programs; however, the weekly programs were preferred by the community because of the lower time constraints and the lower opportunity cost of time. The willingness of community and household members to invest their time in more intensive activities in the daily programs led to better program outcomes.

RESUMO

BACKGROUND: Inappropriate nutrition knowledge and feeding practices of caregivers are among several important causes of persistent malnutrition problems in young children. Thus, it is essential to provide caregivers with the necessary knowledge to help them modify their feeding practices. OBJECTIVE: To examine the effectiveness of two different nutrition education methods, weekly intensive nutrition education (INE) and monthly nonintensive nutrition education (NNE), designed for caregivers of mildly wasted children (weight-for-height z-score ≥ -1.5 to < -1) aged ≥ 6 to < 60 months on Nias Island, Indonesia. METHODS: To assess the impact of the two different nutrition education approaches on nutrition knowledge and practice of caregivers with their children, respondents were assigned to receive either weekly INE (n=114) or monthly NNE (n=96). The knowledge and practice levels of the mothers in each group were assessed and compared using a pretested validated questionnaire at admission and after the intervention period. RESULTS: At admission, the knowledge and practice levels of caregivers in both groups were not statistically significantly different. After participating in the nutrition education program, the percentage of correct answers on nutrition knowledge and practice in the INE group was significantly higher than that in the NNE group. Significant improvement in knowledge and practice scores was observed in the INE group after the intervention (p < 0.001), whereas only a significant improvement in knowledge was found in the NNE group (p < .05). CONCLUSIONS: In comparison with NNE, the INE approach was significantly better in bringing about a positive change in knowledge and practice of caregivers of mildly wasted children in the study area.

RESUMO

Interleukin 1ß (IL-1ß) and tumor necrosis factor α (TNF-α) are key cytokines that drive the production of inflammatory mediators and matrix-degrading enzymes in osteoarthritis (OA). These proinflammatory cytokines bind to their respective cell surface receptors and activate inflammatory signaling pathways culminating with the activation of nuclear factor κB (NF-κB), a transcription factor that can be triggered by a host of stress-related stimuli including, excessive mechanical stress and ECM degradation products. Once activated, NF-κB regulates the expression of many cytokines, chemokines, adhesion molecules, inflammatory mediators, and several matrix-degrading enzymes. Therefore, proinflammatory cytokines, their cell surface receptors, NF-κB and downstream signaling pathways are therapeutic targets in OA. This paper critically reviews the recent literature and outlines the potential prophylactic properties of plant-derived phytochemicals such as curcumin and resveratrol for targeting NF-κB signaling and inflammation in OA to determine whether these phytochemicals can be used as functional foods.

RESUMO

Early identification of inadequate intake of nutrients from a person's diet is usually crucial to prevent the development of micronutrient malnutrition. However, there is no single dietary assessment tool for Ethiopia that can assess the nutrient intake of a person from the type of food she or he consumed with a given amount. Therefore, the Calculator for Inadequate Micronutrient Intake (CIMI) application was adapted in consideration of food and nutrition contexts in Ethiopia and validated for its suitability to compute nutrient intake and identify nutrient intake inadequacy. For this, a 24-h recall quantitative dietary data of children aged 12-23 months (n = 781) and lactating mothers (n = 1086) were collected between February 15 and 30, 2017, from rural Genta Afeshum district, Tigray region, Ethiopia. An individual nutrient intake was estimated by calculating using CIMI-Ethiopia and also by NutriSurvey (NS) software for comparison. The average (mean and median) intake of energy and most nutrients and the prevalence of inadequacy calculated by the two software for the children aged 12-23 months and lactating mothers were comparable, except that of the vitamin A. The correlation coefficients for the intake results calculated by CIMI-Ethiopia and NS were between 0.85 and 0.97 for the children and between 0.5 and 0.96 for the lactating mothers' group. Most of the mean intake differences calculated by the two methods were within the acceptable limits, except for the vitamins A, D, and B12 in the Bland-Altman plots. CIMI-Ethiopia is very sensitive to identifying energy, protein, and selected micronutrients inadequacy included in this study, both for the lactating mothers (84.1%-100%) and 12-23-month-old children (77.6%-100%) group. Our results showed that CIMI-Ethiopia estimates the energy and nutrient intake, and can be also used as a screening tool to identify energy, protein, and selected micronutrients inadequacy from an individual woman's and child's diet in rural Tigray, Ethiopia.

RESUMO

Motivation: Countries facing challenges of nutrition security confront a trade-off when dealing with pandemics such as COVID-19. Implementing lockdown measures, widely used worldwide, can help "flatten the curve" (of disease), but such measures may worsen nutrition security. Purpose: We aim to identify and justify nutrition-sensitive lockdown measures to reduce trade-offs with nutrition security. Methods and approach: We propose a conceptual framework which distinguishes eight lockdown measures and six pathways to nutrition security. To demonstrate the relevance of the pathways, we reviewed emerging literature on COVID-19 and nutrition security. We analysed the content of 1,188 newspaper articles on lockdown effects in five African countries - Benin, Ghana, Kenya, Uganda and Zambia. Findings: Some lockdown measures, such as closing workplaces and restricting movement, potentially worsen nutrition far more than others - banning events and public gatherings have far lesser impacts on nutrition. This can be seen from the framework, literature, and is supported by the analysis of newspaper reports in the five countries. Policy implications: It is better when possible to test and trace disease than to lockdown. But when lockdowns are needed, then first recourse should be to measures that have few nutritional consequences, such as banning public events. When more drastic measures are necessary, look to mitigate nutritional harm by, for example, exempting farm labour from restrictions on movement, by replacing school meals with take-home rations, and, above all, providing income support to households most affected and most vulnerable.

RESUMO

BACKGROUND: Trace elements and vitamins, named together micronutrients (MNs), are essential for human metabolism. Recent research has shown the importance of MNs in common pathologies, with significant deficiencies impacting the outcome. OBJECTIVE: This guideline aims to provide information for daily clinical nutrition practice regarding assessment of MN status, monitoring, and prescription. It proposes a consensus terminology, since many words are used imprecisely, resulting in confusion. This is particularly true for the words "deficiency", "repletion", "complement", and "supplement". METHODS: The expert group attempted to apply the 2015 standard operating procedures (SOP) for ESPEN which focuses on disease. However, this approach could not be applied due to the multiple diseases requiring clinical nutrition resulting in one text for each MN, rather than for diseases. An extensive search of the literature was conducted in the databases Medline, PubMed, Cochrane, Google Scholar, and CINAHL. The search focused on physiological data, historical evidence (published before PubMed release in 1996), and observational and/or randomized trials. For each MN, the main functions, optimal analytical methods, impact of inflammation, potential toxicity, and provision during enteral or parenteral nutrition were addressed. The SOP wording was applied for strength of recommendations. RESULTS: There was a limited number of interventional trials, preventing meta-analysis and leading to a low level of evidence. The recommendations underwent a consensus process, which resulted in a percentage of agreement (%): strong consensus required of >90% of votes. Altogether the guideline proposes sets of recommendations for 26 MNs, resulting in 170 single recommendations. Critical MNs were identified with deficiencies being present in numerous acute and chronic diseases. Monitoring and management strategies are proposed. CONCLUSION: This guideline should enable addressing suboptimal and deficient status of a bundle of MNs in at-risk diseases. In particular, it offers practical advice on MN provision and monitoring during nutritional support.

RESUMO

The Codex Alimentarius provides the food standards and guidelines recognized by the World Trade Organization as the primary authority for use in settlement of related trade disputes. Codex bases its decisions primarily on scientific principles and evidence, although other legitimate factors such as economic and societal values may be considered. Codex has two primary aims: to protect consumers' health and assure fair practices in food trade. Codex documents may provide templates for individual nations but are not binding for domestic policies. Despite many advances over the last couple of decades, misunderstandings and controversies have interfered with important aspects of progress which Codex needs to accomplish, especially in the areas of claims of benefits related to food or nutrient consumption and the establishment of the safety of these items. Claims for health benefits should be based on the totality of available scientific evidence, including observational data collected from large populations as well as the results from randomized clinical trials. Safety should be evaluated by risk assessment on high quality experimental data, with anecdotal information having a lesser role. Regulatory policy would be improved if "history of safe use" were to be better defined and described.

RESUMO

The methanolic extract of Cassia hirsuta L. seed materials, an underutilized food legume collected from India, was analyzed for antioxidant activity and health relevant functionality. The methanolic extract of raw seeds contained a total free phenolic content of 15.82 ± 1.69 g catechin equivalent/100 g extract DM. Encouraging levels of ferric reducing/antioxidant power (FRAP, 1,446 mmol Fe[II]/mg extract), inhibition of ß-carotene degradation (48.81%) and scavenging activity against DPPH (64.40%) and superoxide (43.78%) radicals were exhibited by the raw samples. Further, 83.11% of α-amylase and 62.79% of α-glucosidase enzyme inhibition characteristics under in vitro starch digestion bioassay were also recorded. Sprouting + oil-frying caused an apparent increase on the total free phenolic content and a significant improvement in the antioxidant and free radical scavenging capacity of methanolic extract of C. hirsuta seeds, while soaking + cooking as well as open-pan roasting treatments showed diminishing effects. The analysis of the phenolic profile revealed the presence of gallic acid, p-coumaric acid and (+)-catechin in the methanolic extract of these seeds.
