ABSTRACT

Objetivo: investigar a percepção do peso corporal e as dificuldades encontradas pelas pessoas com deficiência visual na aquisição, na preparação e no consumo dos alimentos. Metodologia: estudo observacional transversal, com adultos e idosos com deficiência visual em Pelotas/RS, realizado no período de abril a maio de 2023. Foi utilizado um questionário composto de 42 itens. Os dados coletados foram analisados por análise descritiva e analítica, e apresentados como média ± desvio padrão ou percentual. Resultados: a amostra contou com 20 pessoas, predominantemente do sexo feminino e idosas. Em relação ao consumo alimentar, 50% dos participantes consomem feijão, 75% frutas e hortaliças, 50% bebidas adoçadas, biscoitos recheados e doces. Referente à percepção do peso corporal, percebeu-se que a maior parte do grupo sente que está acima do peso adequado e se sentem "insatisfeitos(as)". Sobre as dificuldades encontradas, 85% dos participantes relataram dificuldade extrema para identificar a validade dos alimentos, 70% para comprar alimentos frescos e perecíveis e 40% para usar a faca para cortar e descascar os alimentos. Conclusão: verificou-se que a maior parte do grupo sente que está acima do peso adequado e estão "insatisfeitos(as)" em relação ao peso corporal. Além disso, dependem de outra pessoa para escolher os alimentos a serem comprados, saber o prazo de validade, preparar alimentos que precisam ser porcionados, servir refeições no prato, cortar carnes, descascar vegetais e frutas, utilizar faca, entre outros. Esta dependência pode influenciar diretamente no seu consumo alimentar quando essas pessoas se encontram sozinhas, optando por consumir alimentos industrializados de fácil preparo ou prontos.


Objective: to investigate the perception of body weight and the difficulties encountered by people with visual impairments in acquiring, preparing and consuming food. Methodology: cross-sectional observational study, with adults and elderly people with visual impairment in Pelotas/RS, carried out from April to May 2023. A questionnaire composed of 42 items was used. The collected data were analyzed using descriptive and analytical analysis, and presented as mean ± standard deviation or percentage. Results: the sample included 20 people, predominantly female and elderly. Regarding food consumption, 50% of participants consume beans, 75% fruits and vegetables, 50% sweetened drinks, stuffed cookies and sweets. Regarding the perception of body weight, it was noticed that the majority of the group feels that they are overweight and feel "dissatisfied". Regarding the difficulties encountered, 85% of participants reported extreme difficulty in identifying the expiration date of food, 70% in purchasing fresh and perishable foods and 40% in using a knife to cut and peel food. Conclusion: it was found that the majority of the group feels that they are overweight and are "dissatisfied" with their body weight. Furthermore, they depend on someone else to choose the food to be purchased, know the expiration date, prepare food that needs to be portioned, serve meals on the plate, cut meat, peel vegetables and fruits, use a knife, among others. This dependence can directly influence their food consumption when these people are alone, choosing to consume easily prepared or ready-made processed foods.

ABSTRACT

Introducción. La calidad de la alimentación implica tanto la cantidad y calidad de los alimentos que se ofrecen como la forma en que se ofrecen, el entorno y las respuestas de quien los ofrece. El objetivo de este trabajo fue identificar patrones de comportamiento relacionados a la alimentación perceptiva en niños entre 6 y 23 meses de áreas urbanas de la Argentina en 2018-19. Población y métodos. Análisis secundario de datos de la 2da Encuesta Nacional de Nutrición y Salud 2018-19, de una muestra probabilística polietápica de localidades urbanas de 5000 habitantes y más de Argentina. Se realizó análisis descriptivo y análisis de componentes principales para identificar los patrones de alimentación perceptiva en 4379 niños y niñas de 6 a 23 meses. Resultados. Se identificaron cinco patrones de alimentación perceptiva, las dos primeras dimensiones explicaron el 71,1 % de la inercia (p = 0,013). El patrón donde prevalecía la posibilidad de experimentación, la autonomía, la interacción y la ausencia de pantallas, premios y distracciones se asoció a niños/as mayores de 12 meses, de las regiones del centro y sur (Cuyo, Pampeana, Gran Buenos Aires y Patagonia), mientras que el patrón relacionado con menor autonomía, experimentación y autorregulación correspondió a las regiones Noroeste y Noreste, y a niños/as entre 6 y 11 meses. Conclusión. Se evidencian prácticas de alimentación perceptiva que se corresponden con patrones diferenciados entre sí, asociados a diferentes etapas y a la región donde viven los niños/as.


Introduction. Dietary quality involves both the quantity and quality of food offered, the way and the setting in which it is offered, and the responses of the person offering it. The objective of this study was to identify behavioral patterns related to responsive feeding in children aged 6 to 23 months in urban areas from Argentina in 2018­2019. Population and methods. Secondary analysis based on data from the second National Survey on Nutrition and Health of 2018­2019 conducted in a multistage probability sample from urban areas of 5000 inhabitants or more in Argentina. A descriptive analysis and a principal component analysis were performed to identify responsive feeding patterns in 4379 children aged 6 to 23 months. Results. Five responsive feeding patterns were identified; the first 2 dimensions explained 71.1% of inertia (p = 0.013). The pattern with a prevailing possibility of experimentation, autonomy, interaction, and the absence of screens, rewards and distractions was associated with children older than 12 months from the central and south regions (Cuyo, Pampa, Greater Buenos Aires, and Patagonia), whereas the pattern related to a lower autonomy, experimentation, and self-regulation corresponded to children aged 6 to 11 months from the Northwest and Northeast regions. Conclusion. There is evidence of responsive feeding practices that correspond to distinguishable patterns, associated with different stages of life and with the region where the children live

ABSTRACT

ABSTRACT Introduction: The importance of dietitians in dialysis units is indisputable and mandatory in Brazil, but little is known about the practices adopted by these professionals. Objective: To know practices adopted in routine nutritional care, focusing on nutritional assessment tools and treatment strategies for people at risk or diagnosed with malnutrition. Methodology: Electronic questionnaire disseminated on social media and messaging applications. It included questions that covered dietitians' demographic and occupational profile characteristics and of the dialysis unit, use and frequency of nutritional assessment tools, nutritional intervention strategies in cases of risk or diagnosis of malnutrition, prescription and access to oral supplements. Results: Twenty four percent of the Brazilian dialysis units (n = 207) responded electronically. The most used nutritional assessment tools with or without a pre-established frequency were dietary surveys (96%) and Subjective Global Assessment (83%). The strategies in cases of risk or presence of malnutrition used most frequently (almost always/always) were instructions to increase energy and protein intake from foods (97%), and increasing the frequency of visits (88%). The frequency of prescribing commercial supplements with standard and specialized formulas was quite similar. The availability of dietary supplements by the public healthcare system to patients varied between regions. Conclusion: Most dietitians use various nutritional assessment tools and intervention strategies in cases of risk or malnutrition; however, the frequency of use of such tools and strategies varied substantially.


Resumo Introdução: A importância da atuação do nutricionista em unidades de diálise é indiscutível e obrigatória no Brasil, porém pouco sabemos sobre as práticas adotadas por esses profissionais. Objetivo: Conhecer práticas adotadas na rotina dos atendimentos nutricionais, com foco nas ferramentas de avaliação nutricional e nas estratégias de tratamento das pessoas com risco ou diagnóstico de desnutrição. Metodologia: Questionário eletrônico divulgado em mídias sociais e aplicativos de mensagens. Incluiu questões que abrangiam características do perfil demográfico e ocupacional do profissional e da unidade de diálise, utilização e frequência de ferramentas de avaliação nutricional, estratégias de intervenção nutricional em casos de risco ou diagnóstico de desnutrição e prescrição e acesso a suplementos alimentares orais. Resultados: Foram recebidos eletronicamente o equivalente a 24% das unidades de diálise brasileiras (n = 207). As ferramentas de avaliação nutricional mais utilizadas com ou sem frequência pré-estabelecida foram inquéritos dietéticos (96%) e Avaliação Global Subjetiva (83%). As estratégias em casos de risco ou presença de desnutrição utilizadas com mais frequência (quase sempre/sempre) foram a orientação de incremento energético e proteico por meio de alimentos (97%) e o aumento da periodicidade das visitas (88%). A frequência de prescrição de suplemento industrializado de fórmula padrão e especializada foi bastante semelhante. A disponibilização de suplementos alimentares pelo Sistema Único de Saúde aos pacientes variou entre as regiões. Conclusão: A maior parte dos nutricionistas utiliza diversas ferramentas de avaliação nutricional e estratégias de intervenção em casos de risco ou desnutrição, porém a frequência de utilização de tais ferramentas e estratégias foi bastante variada.

ABSTRACT

Anastrepha fraterculus (Diptera: Tephritidae) is considered an important pest in Neotropical countries. The laboratory rearing of this species should reproduce conditions in nature; thus, special attention is required to the nutritional quality of diets for larval development. Protein components (wheat germ) are costly and account for most production costs in lab insect rearing. In this sense, this work aimed to identify ingredients to replace wheat germ, without compromising diet quality for the lab rearing of A. fraterculus. We tested diets composed of whole rice flour, corn flour, and a mixture of whole wheat flour + soybean flour as substitutes for wheat germ as well as a raw wheat germ diet, considered the control. The protein sources used in the larval diet influenced the biological performance of both the larval and adult stages of A. fraterculus during six generations. The diet containing corn flour and wheat germ showed similar results in the different developmental parameters. The diet with rice flour also provided adequate biological development for A. fraterculus throughout its life cycle and was nutritionally similar to the control. As it is local product, rice flour can replace wheat germ (costly imported product) in artificial diets for A. fraterculus, reducing production costs by roughly 30% without compromising the biological and nutritional parameters of the insects. Faced with this, the rice flour can be considered suitable for the mass rearing of A. fraterculus in the laboratory.

ABSTRACT

BACKGROUND: COVID-19 is a systemic infection with a significant impact on nutrition risk and the hematopoietic system. The neutrophil-lymphocyte ratio (NLR) may have prognostic value in determining severe cases of COVID-19 and the urea-creatinine ratio (UCR) is currently being studied as a potential biomarker of catabolism associated with critical illness. The aim was to assess the association between the NLR, UCR and C-reactive protein (CRP) with nutritional risk in hospitalized patients with COVID-19. METHODS: This is a retrospective cross-sectional study that assessed 589 hospitalized patients with COVID-19, 18 years of age or older, of both sexes. Nutritional risk was assessed by Nutritional Risk Screening (NRS, 2002) and NLR by neutrophils divided by lymphocyte count. The UCR was calculated by the ratio between urea and creatinine and quantified by the calorimetric biochemical method and CRP by the immunoturbidimetric method. Differences between groups were applied by the Mann-Whitney U test and the automated binary regression test. RESULTS: Of the 589 patients, 87.4% were at nutritional risk. When evaluating patients admitted to the ICU, 91.9% were at nutritional risk. Patients with NRS ≥3 are older, with lower body mass and BMI, higher NLR and UCR and lower CRP values. However, 73% of patients admitted to the ward were at nutritional risk, and only age differed between groups, being higher in patients with NRS ≥3. Logistic regression showed a weak association between nutritional risk in NRS and UCR (Model 1) (OR = 0.96, 95%CI: 0.94-0.99, p = 0.003) and NRS with CRP (Model 1) (OR = 1.01, 95%CI: 1.00-1.02, p < 0.001) in patients in the ICU. On the other hand, the logistic regression in ward patients found association only for CRP in both models (Model 1, OR = 1.01, 95%CI: 1.00-1.01, p = 0.041) and (Model 2, OR = 1.01, 95%CI: 1.00-1.01, p = 0.031). CONCLUSION: We found a weak association between nutritional risk and UCR and CRP levels in patients admitted to the ICU, while in the ward patients the nutritional risk also had weak association with CRP.

ABSTRACT

While research on complementary and alternative medicine (CAM) for the general population is expanding, there remains a scarcity of studies investigating the efficacy and utilisation of CAM practices, specifically in the paediatric population. In accordance with the World Health Organization (WHO), the prevalence of the parental utilisation of CAM in their dependents is estimated to reach up to 80%. This literature review identified broad, heterogeneous, and inconclusive evidence regarding CAM's applications and effectiveness, primarily attributed to variance in sociodemographic factors and differences in national healthcare systems. Additionally, the review identified a lack of consensus and polarised positions among mainstream professionals regarding the mechanisms of action, applications, and effectiveness of CAM. This narrative review presents varied results concerning the efficacy of most CAM therapies and their applications; however, some evidence suggests potential benefits for acupuncture, yoga, tai chi, and massage in improving physical and mental health. Moreover, the available evidence indicates that meditation may enhance mental health, while reiki may only influence patients' perceptions of comfort. In light of the intricate and multifaceted nature of herbal medicine, it is imperative to assess its efficacy on a case-by-case basis, taking into account the specific compounds and procedures involved. This comprehensive review serves as a valuable resource for health professionals, offering guidance for personalised healthcare approaches that consider the values and beliefs of patients, thereby facilitating integrated, evidence-based practices aimed at enhancing the quality of healthcare services and patient satisfaction.

ABSTRACT

This study aimed, for the first time, to determine the nutritional composition, beta-glucan and ergosterol contents, phenolic compound composition, and biological and functional activities of a novel mycoprotein produced through a bioconversion process of Durvillaea spp., a brown seaweed. An untargeted metabolomics approach was employed to screen metabolites and annotate molecules with nutraceutical properties. Two products, each representing a distinct consortia of co-cultured fungi, named Myco 1 and Myco 2, were analysed in this study. These consortia demonstrated superior properties compared to those of Durvillaea spp., showing significant increases in total protein (~238%), amino acids (~219%), and ß-D-glucans (~112%). The protein contains all essential amino acids, a low fatty acid content, and exhibits high antioxidant activity (21.5-25.5 µmol TE/g). Additionally, Myco 2 exhibited the highest anti-alpha-glucosidase activity (IC50 = 16.5 mg/mL), and Myco 1 exhibited notable anti-lipase activity (IC50 = 10.5 mg/mL). Among the 69 top differentially abundant metabolites screened, 8 nutraceutical compounds were present in relatively high concentrations among the identified mycoproteins. The proteins and polysaccharides in the mycoprotein may play a crucial role in the formation and stabilization of emulsions, identifying it as a potent bioemulsifier. In conclusion, the bioconversion of Durvillaea spp. results in a mycoprotein with high-quality protein, significant nutritional and functional value, and prebiotic and nutraceutical potential due to the production of unique bioactive compounds.

ABSTRACT

BACKGROUND AND AIMS: Correctly characterizing malnutrition is a challenge. Transthyretin (TTR) rapidly responds to adequate protein intake/infusion, which could be used as a marker to identify malnutrition. Nutritional therapy is used to prevent malnutrition. Parenteral nutrition (PN) requires daily monitoring to determine whether what is being offered is adequate. This article aims to investigate whether the practice of measuring TTR is justified. METHODS: Data from patients admitted to the ward or intensive care unit (ICU) were collected at three different times: within the first 72 h (T1) of PN use, on the 7th day (T2), and the 14th day (T3) after the initial assessment. RESULTS: 302 patients were included; the average age was 48.3 years old; the prevalence of death was 22.2%, and 61.6% of the sample were male. TTR values and the effectiveness of nutritional support in these patients were not associated with the outcome; however, meeting caloric needs was related to the outcome (p = 0.047). No association was found when TTR values were compared to the nutritional status. Thus, TTR was not a good indicator of nutritional risk or nutritional status in hospitalized patients. CONCLUSIONS: Undoubtedly, the TTR measurement was inversely proportional to CRP measurements. It was possible to conclude in this follow-up cohort of hospitalized patients that TTR values were not useful for determining whether the patient was malnourished, predicting death or effectiveness of nutritional support, yet based upon our analyses, a decrease in TTR greater than 0.024 units for every 1 unit increase in CRP might be due to ineffective nutritional supply.

ABSTRACT

The health benefits of nut consumption have been extensively demonstrated in observational studies and intervention trials. Besides the high nutritional value, countless evidences show that incorporating nuts into the diet may contribute to health promotion and prevention of certain diseases. Such benefits have been mostly and certainly attributed not only to their richness in healthy lipids (plentiful in unsaturated fatty acids), but also to the presence of a vast array of phytochemicals, such as polar lipids, squalene, phytosterols, tocochromanols, and polyphenolic compounds. Thus, many nut chemical compounds apply well to the designation "nutraceuticals," a broad umbrella term used to describe any food component that, in addition to the basic nutritional value, can contribute extra health benefits. This contribution analyses the general chemical profile of groundnut and common tree nuts (almond, walnut, cashew, hazelnut, pistachio, macadamia, pecan), focusing on lipid components and phytochemicals, with a view on their bioactive properties. Relevant scientific literature linking consumption of nuts, and/or some of their components, with ameliorative and/or preventive effects on selected diseases - such as cancer, cardiovascular, metabolic, and neurodegenerative pathologies - was also reviewed. In addition, the bioactive properties were analyzed in the light of known mechanistic frameworks.

ABSTRACT

Introducción. La calidad de la alimentación es un derecho vinculado con la supervivencia, el crecimiento saludable, la prevención de enfermedades crónicas y malnutrición en todas sus formas. El objetivo de este trabajo fue analizar las prácticas de lactancia y de alimentación de menores de 2 años de áreas urbanas de la Argentina en 2018-19, según el nivel de ingreso de los hogares. Población y métodos. Estudio secundario con datos de la 2da. Encuesta Nacional de Nutrición y Salud 2018-19. Se analizaron indicadores de lactancia y alimentación complementaria, según metodología de la Organización Mundial de la Salud (OMS) y Unicef. Se estratificó según nivel de ingresos del hogar. Resultados. El análisis incluyó 5763 menores de 24 meses. Aunque el 97 % fue alguna vez amamantado, solo el 47 % de los menores de 6 meses tuvo lactancia exclusiva el día previo y el 48 % mantenía la lactancia luego del año, con mayor prevalencia en los niños/as de menores ingresos. En el día previo, el 23 % de los niños/as de 6 a 23 meses no consumió ninguna verdura o fruta; el 60 % consumió alimentos no saludables y el 50 %, bebidas dulces. Las bebidas dulces y la ausencia de frutas y verduras fueron mayores en aquellos de hogares de menores ingresos. Conclusión. La calidad de la alimentación de los niños/as dista de las recomendaciones y está condicionada por los ingresos. En los sectores empobrecidos, es menor el inicio temprano de la lactancia, la diversidad alimentaria mínima y el consumo de frutas y verduras, y es mayor el consumo de bebidas dulces.


Introduction. Diet quality is a right related to survival, healthy growth, prevention of chronic diseases, and malnutrition in all its forms. The objective of this study was to analyze breastfeeding and feeding practices in children younger than 2 years from urban areas of Argentina in 2018­2019 according to their household income level. Population and methods. Secondary analysis of data of the Second National Survey on Nutrition and Health (ENNyS2) of 2018­2019. Breastfeeding and complementary feeding indicators proposed by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) were analized. Data were stratified by household income level. Results. The analysis included 5763 children younger than 24 months old. Although 97% was ever breastfed, only 47% of infants younger than 6 months were exclusively breastfed the previous day and 48% continued with breastfeeding after 1 year old, with a higher prevalence in low-income children. The previous day, 23% of children aged 6 to 23 months did not eat any fruit or vegetable, 60% consumed unhealthy foods, and 50% consumed sweet beverages. The consumption of sweet beverages and the absence of fruit and vegetables were higher in low-income households. Conclusion. The quality of children's diet is far from the recommendations and is conditioned by income. Early initiation of breastfeeding, minimum dietary diversity, fruit and vegetable consumption are lower and sweet beverage consumption is greater in impoverished sectors.

ABSTRACT

Este estudio partió de una caracterización nutricional en atletas, atendidos desde el punto de vista académico y científico por la Universidad Técnica "Luis Vargas Torres", de Ecuador. Llamó la atención a entrenadores y profesores de este centro pedagógico deportivo que, a pesar de contar con las condiciones básicas adecuadas para la práctica del deporte, se mostraron resultados deportivos desfavorables. Entre los datos recogidos en el estudio exploratorio (encuesta a entrenadores y entrevista a directivos y profesores) se destacó el insuficiente régimen dietético nutricional recibido por los deportistas. Se planteó como objetivo proponer un conjunto de recomendaciones nutricionales que permita perfeccionar las estrategias dietéticas que necesitan los atletas para mantenerse en un estado óptimo en su práctica deportiva y su salud. El diagnóstico, se sustentó en la medición y análisis estadísticos como la correlación de intensidad (Sprints) e ingesta de carbohidratos y la correlación intensidad e ingesta de proteínas. Después de analizar los resultados, se diseñaron y establecieron un grupo de recomendaciones dietéticas enfocadas en mejorar la situación formativa deportiva. Se sugiere que futuras investigaciones profundicen en esta área, para validar y mejorar el marco analítico propuesto.


Este estudo partiu de uma caracterização nutricional em atletas, atendida do ponto de vista acadêmico e científico pela Universidade Técnica "Luis Vargas Torres", do Equador. Chamou a atenção dos treinadores e professores deste centro pedagógico desportivo que, apesar de apresentarem as condições básicas adequadas à prática desportiva, apresentavam resultados desportivos desfavoráveis. Dentre os dados coletados no estudo exploratório (pesquisa com treinadores e entrevistas com dirigentes e professores), destacou-se o insuficiente regime alimentar nutricional recebido pelos atletas. O objetivo foi propor um conjunto de recomendações nutricionais que permitissem aperfeiçoar as estratégias alimentares que os atletas necessitam para se manterem num estado óptimo na sua prática desportiva e saúde. O diagnóstico foi baseado em medidas e análises estatísticas como a correlação de intensidade (Sprints) e ingestão de carboidratos e a correlação de intensidade e ingestão de proteínas. Após a análise dos resultados, foi desenhado e estabelecido um conjunto de recomendações dietéticas focadas na melhoria da situação do treino desportivo. Sugere-se que pesquisas futuras se aprofundem nesta área, para validar e aprimorar o arcabouço analítico proposto.


This study is based on a nutritional characterization of athletes, attended from an academic and scientific point of view by the Luis Vargas Torres Technical University, of Ecuador. It draws the attention of coaches and teachers of this sports pedagogical center that, despite having the appropriate basic conditions for the practice of sports, unfavorable sports results are shown. Among the data collected in the exploratory study (survey of coaches and interviews with managers and teachers), the insufficient nutritional dietary regimen received by athletes was highlighted. The objective was to propose a set of nutritional recommendations that allow perfecting the dietary strategies that athletes need to remain in an optimal state in their sports practice and health. The diagnosis was based on measurement and statistical analysis such as the correlation of intensity (Sprints) and carbohydrate intake and the correlation of intensity and protein intake. After analyzing the results, a group of dietary recommendations focused on improving the sports training situation are designed and established. It is suggested that future research delve into this area, to validate and improve the proposed analytical framework.

ABSTRACT

OBJECTIVE: The objective of this study was to describe feeding practices and weight status in a cohort of children with congenital Zika syndrome (CZS) in northeastern Brazil. METHODS: This longitudinal study of children with CZS (N = 156) included data collection on child feeding practices and weight status at five timepoints between 2018 and 2022. The average age of the children was 32.1 months at enrollment and 76.6 months at the fifth assessment. Multilevel models, with repeated observations nested within children, were used to estimate time-related differences in each outcome. RESULTS: Use of enteral feeding, such as gastrostomy, increased from 19.2% to 33.3% over 4 years (p < .001). Among children who did not exclusively use an enteral feeding method, the percentage experiencing at least one dysphagia-associated behavior, such as coughing or gagging, increased from 73.9% to 85.3% (p = .030) while consuming liquids and from 36.2% to 73.5% (p = .001) while consuming solids. Based on weight-for-age z-scores, the percentage of children who were moderately or severely underweight increased from 42.5% to 46.1% over the 4 years but was not statistically significant. Children exclusively using an enteral feeding method had significantly decreased odds of being underweight at assessments 3, 4, and 5. CONCLUSIONS: These data highlight the ongoing and increasing challenges of feeding young children with CZS. Our findings elucidate the physiological reasons children with CZS may be underweight and point to intervention targets, such as enteral feeding, to improve their feeding practices.

ABSTRACT

OBJECTIVE: This study aimed to verify the dietary adequacy of full enteral feeding in preterm newborns (PTNB) and its relationship with birth weight (BW) during the period of hospitalization in the neonatal intensive care unit (NICU). METHODS: This is a prospective cohort study whose population were babies born at less than 37 gestational weeks and weighing less than 2500 g, admitted to a NICU. PTNB were monitored regarding their dietary evolution, considering parenteral and enteral nutrition and adequacy of diet supply in terms of volume, energy, and protein. For statistical analysis, the Statistical Package for the Social Sciences (SPSS) software was used, considering p < 0.05 as significant. RESULTS: A total of 76 PTNB were included. The mean time of using parenteral nutrition was 14 days. The mean time to reach the full enteral feeding for nutrition (FEF-N) was 29 days. However, half of the PTNB reached nutritional recommendations after this means. The time to achieve FEF-N was influenced by BW. Additionally, BW significantly influenced the length of stay in the NICU (p < 0.001). When reaching the recommended full enteral feeding for hydration (FEF-H), 60% of the sample was unable to reach the recommended energy and protein intake. CONCLUSIONS: BW influenced the time needed to reach the FEF-H and FEF-N. The lower the BW, the longer it took to achieve dietary adequacy. Despite achieving the FEF-H, most premature babies did not reach the necessary energy and protein intake at the appropriate time.

ABSTRACT

Physical activity is essential for healthy aging. This study aimed to identify an association between physical performance, body fat percentage (%BF), and the perception of oral health-related quality of life (OHRQoL) in independent older adults. METHOD: A group of active older adults was selected from a government-sponsored reunion center in Mexico City. OHRQoL was assessed using the General Oral Health Index (GOHAI), and nutritional status was assessed using the Mini Nutritional Assessment (MNA) tool. A short physical performance battery (SPPB) was applied, and, for body composition, DXA (dual X-ray absorptiometry) was conducted. Data were analyzed using logistic regression models, and marginal probabilities were obtained. RESULTS: This study involved 366 participants; their mean age was 73.9 (±6.2) years, and 24.9% had type 2 diabetes mellitus (T2DM). OHRQoL information revealed that pain or discomfort in the oral cavity was perceived by 63.9% of the older adults during the previous three months. The SPPB score was low in 159 (43.44%) participants. The logistic regression model revealed that age (OR = 1.13, p < 0.001), T2DM (OR = 2.10, p = 0.009), the risk of malnutrition/malnutrition (OR = 1.76, p = 0.047), high %BF (OR = 1.09, <0.001), and poor OHRQoL (OR = 1.96, p = 0.009) were associated with deteriorated physical performance. CONCLUSION: OHRQoL self-perception, excess body fat, and nutritional status impacted physical performance. Aging well requires a comprehensive approach.

ABSTRACT

BACKGROUND/OBJECTIVES: Brazil and Mozambique face similar socioeconomic challenges, including common indicators of undernutrition and overnutrition among children. This study evaluated the similarity degree of the anthropometric and body composition variables of Brazilian and Mozambican children by using the Jaccard index. METHODS: A total of 1831 children of both genders aged 7-10 years from three Brazilian cities (Recife, Vitoria de Santo Antao, and Lagoa do Carro) and three Mozambican cities (Maputo, Boane, and Inhambane) participated in this study. Anthropometric (height, body mass, and waist circumference) and body composition (body fat percentage [%BF], lean mass, and fat mass) variables were measured and the Smoothed Jaccard Index Surface (SJIS) was used to evaluate the similarity degree. RESULTS: Brazilian children were taller and heavier and had a higher %BF and fat mass than Mozambican children. Children living in urban areas were taller than those living in rural zones in both countries. Brazilian and Mozambican children showed high similarity only between %BF and lean mass. Children from Recife and Maputo had high similarities among waist circumference, body mass, fat mass, height, and %BF. Finally, a high SJIS degree was observed among height and %BF for schoolchildren from rural and urban zones. CONCLUSION: Brazilian and Mozambican children exhibit differences in growth characteristics but a high degree of similarity when children from rural and urban zones are compared.

ABSTRACT

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has posed unprecedented challenges to global health systems, particularly among vulnerable populations such as the elderly. Understanding the interplay between anthropometric markers, molecular profiles, and disease severity is crucial for effective clinical management and intervention strategies. We conducted a cohort study comprising 43 elderly COVID-19 patients admitted to São Lucas Hospital, PUCRS, Brazil. Anthropometric measurements, including calf circumference (CC) and abdominal circumference (AC), were assessed alongside molecular analyses of peripheral blood samples obtained within 48 h of hospital admission. Sociodemographic data were collected from electronic medical records for comprehensive analysis. Our findings revealed a possible relationship between overweight status, increased abdominal adiposity, and prolonged hospitalization duration, alongside heightened disease severity. We also found no significant correlations between BMI, vitamin D levels, and clinical outcomes. Elevated oxygen requirements were observed in both normal and overweight individuals, with the latter necessitating prolonged oxygen therapy. Molecular analyses revealed changes in the inflammatory profile regarding the outcome of the patients. Our study highlights the critical importance of both anthropometric and molecular markers in predicting disease severity and clinical outcomes in elderly individuals with COVID-19.

ABSTRACT

Food waste is responsible for the loss of 1.3 billion tons of food, some of which are related to by-products with great nutritional and energy potential that are still underexplored, such as safflower cake derived from the oil extraction industry. Therefore, the aim of this study was to evaluate the effects of incorporating safflower cake (Carthamus tinctorius) and the mixing method used to produce composite wheat-based flour in order to develop a new ingredient. The results were analyzed using ANOVA, and the Tukey test was applied at a significance level of 5 %. The composite flours obtained by the conventional mixing method showed, when compared to wheat flour, a higher concentration of proteins (+5g 100 g-1), minerals (+86 mg kg-1 of Fe, +30 mg kg-1 of Zn), phenolic compounds (15 mg GAE g-1), flavonoids (0.3 mg QE g-1), and lower oil absorption (-0.5 g oil g sample-1), making them suitable for hot flour-based sauces, salad dressings, frozen desserts, cookies and fried products. While extruded composite flours presented better homogenization, reduction of moisture (1 g 100 g-1), lipids (3 g 100 g-1), and mycotoxin concentrations, increased antioxidant activity (DPPH -0.07 IC50 mg/L and ORAC +9 µmol Trolox Eq/g), water absorption and solubility indexes, and oil absorption index, making it suitable for bakery products, meat, and dairy sausages. The developed composite flour proved to be a good nutritional ingredient; thus, its consumption can represent an important nutritional strategy with low production costs, as well as a sustainable solution, reducing food waste and, therefore, toward the concepts of the circular economy.

ABSTRACT

With the increasing need to promote healthy and sustainable diets, seaweeds emerge as an environmentally friendly food source, offering a promising alternative for food production. The aim of this study was to characterize the brown seaweed Sargassum filipendula from the coast of São Paulo, Brazil, regarding its nutritional and techno-functional properties using two dehydration methods, oven drying and lyophilized. A commercial dried sample was used as a control. Analyses of proximate composition, mineral determination, amino acid determination, antioxidant capacity, pH, color, scanning electron microscopy, X-ray diffraction, thermal properties, Fourier-transform infrared spectroscopy, and techno-functional properties were performed. Seaweed flours showed significant differences in physicochemical composition, with dietary fiber content of seaweed flours exceeding 70 %. Glutamic and aspartic acids were the most abundant amino acids, with contents of 88.56 and 56.88 mg/g of protein in Sargassum oven drying. Both for antioxidant potential and bioactive compounds, Sargassum lyophilized flours showed the highest levels of compounds. Sargassum lyophilized exhibited lighter color compared to Sargassum oven drying and Sargassum commercial. Emulsion formation, foam formation capacity and stability were higher in Sargassum lyophilized, as well as water and oil absorption. The results suggest that seaweeds can be used to formulate a wide variety of food products, such as sausages, bread, cakes, soups, and sauces.

ABSTRACT

Introduction: Frequent consumption of ultra-processed foods (UPFs) during pregnancy is linked to excess intake of added sugar, fat, and sodium and inadequacy of several micronutrients. Diet quality during pregnancy should be maximized as inadequate levels of key nutrients and excessive intake of energy and added sugar might influence mother-child health. We aimed to estimate the contribution (% of total calories) of ultra-processed products to the total energy intake by pre-gestational body mass index (BMI) categories and Hb status during pregnancy in participants from the MAS-Lactancia Cohort. Methods: Pre-gestational weight, hemoglobin levels, 24-h dietary intake recall interviews, and sociodemographic data were collected during the second and third trimesters of pregnancy. Reported consumed foods were categorized using the NOVA classification, and the contribution of calories from each NOVA category was estimated using the Mexican Food Database. We estimated medians and interquartile ranges (p25 and p75) for dietary intake and energy contributions. The comparison of intake between the second and third trimesters was done using the Wilcoxon test. In addition, a quantile regression model with an interaction between pre-gestational BMI and Hb levels status in tertiles over the percentage of energy from UPFs was adjusted by age and socioeconomic status. Results: The contribution to total energy intake from UPFs was 27.4% in the second trimester and 27% in the third trimester (with no statistical difference). The percentage of energy intake from UPFs was higher in women who started pregnancy with obesity and presented the lowest levels of Hb (1st tertile), 23.1, 35.8, and 44.7% for the 25th, 50th, and 75th percentiles, respectively, compared to those with normal BMI and the highest tertile of Hb levels: 18, 29.0, and 38.6% for the 25th, 50th, and 75th percentiles, respectively. Conclusion: In conclusion, UPF intake in pregnant women is similar to the general population and was higher for those with pre-gestational obesity and the lowest tertile of Hb levels. UPF contributes also to sugar, saturated fat, and sodium, which may adversely affect the health of mothers and their offspring.

ABSTRACT

BACKGROUND: There is a lack of studies analyzing the association between oral mucositis (OM) and nutritional imbalance in children during hematopoietic stem cell transplantation (HSCT). The aim of this study was to compare the risk factors for OM and nutritional imbalance during HSCT in pediatric patients with nonmalignant diseases (NMD) and malignant diseases (MD). METHODS: Data on age, sex, primary disease, transplantation type, conditioning regimen, GVHD prophylaxis, gastrointestinal toxicity, OM, percent body weight loss or gain, nutritional repositioning, and overall survival (OS) were retrospectively collected from the 132 medical records. The data were then compared between patients with NMD (n = 70) and MD (n = 62). RESULTS: OM had a similar severity between the groups. The primary risk factor for OM in the NMD group was the conditioning regimen with busulfan, while in the MD group it was GVHD prophylaxis with cyclosporin and methotrexate. OM did not have an impact on body weight loss or gain in any of the groups. In the NMD, body weight gain due to fluid overload was more pronounced and associated with a lower age range. OS was similar between the groups and was not affected by OM. CONCLUSIONS: OM pattern was similar in pediatric patients with or without MD, but the factors that determined these oral lesions were different. There were disparities in body weight changes between the two groups, and these changes were not associated to OM.
