ABSTRACT

Background: Potato peel extract has demonstrated the ability to reduce platelet aggregation in vitro, suggesting its potential as a dietary intervention for preventing atherothrombotic disorders. Objective: This study aims to evaluate the impact of a potato peel-rich diet on platelet aggregation. Methods: A randomized, crossover-controlled, open two-period study was carried out with the participation of 12 healthy volunteers. Platelet aggregation was assessed before and after a seven-day dietary intervention. Participants consumed either a diet rich in potato peel (2 g/kg/d) or acetylsalicylic acid (ASA) as a reference (100 mg/d). Platelet aggregation percentages were measured following stimulation with arachidonic acid (AA, 150 µg/mL), adenosine diphosphate (ADP, 10 µM), and collagen (COL, 10 µg/mL). Results: The potato peel-rich diet resulted in a slight but significant reduction in platelet aggregation when stimulated with arachidonic acid compared to baseline values (85.0±2.0% vs. 91.3±1.7%, p<0.05). This effect was less pronounced than the reduction achieved with ASA (16±1.9%, p<0.001). Conclusion: The administration of a diet rich in potato peel reduces platelet aggregation induced by arachidonic acid, suggesting its potential role in the prevention of atherothrombotic disorders.


Introducción: El extracto de cáscara de patata ha demostrado su capacidad para reducir la agregación plaquetaria in vitro, lo que sugiere su potencial como intervención dietética para prevenir trastornos aterotrombóticos. Objetivo: Evaluar el impacto de una dieta rica en cáscara de patata en la agregación plaquetaria. Materiales y métodos: Se llevó a cabo un estudio aleatorizado, controlado, cruzado y abierto con la participación de 12 voluntarios sanos. Se evaluó la agregación plaquetaria antes y después de una intervención dietética de siete días. Los participantes consumieron una dieta rica en cáscara de patata (2 g/kg/d) o ácido acetilsalicílico (ASA) como referente (100 mg/d). Se midieron los porcentajes de agregación plaquetaria después de la estimulación con ácido araquidónico (AA, 150 µg/mL), difosfato de adenosina (ADP, 10 µM) y colágeno (COL, 10 µg/mL). Resultados: La dieta rica en cáscara de patata resultó en una ligera pero significativa reducción en la agregación plaquetaria cuando se estimuló con ácido araquidónico en comparación con los valores iniciales (85,0 ± 2,0% vs. 91,3 ± 1,7%, p <0,05). Este efecto fue menos pronunciado que la reducción lograda con ASA (16 ± 1,9%, p <0,001). Conclusión: La administración de una dieta rica en cáscara de patata reduce la agregación plaquetaria inducida por ácido araquidónico, lo que sugiere su papel potencial en la prevención de trastornos aterotrombóticos.

ABSTRACT

Abstract The present study aimed to determine the effect of different levels of protein on the growth, body composition, amino acid profile and serology of Channa marulius fingerlings. The experiment was conducted in ten happas installed in earthen ponds, each stocked with 10 fishes for 90 days. Four commercial fish feeds having 25%, 30%, 32% and 40% crude protein (CP) levels were fed to fish at 3% of their wet body weight three times a day. The results of the study revealed that highest weight gain, feed conversion ratio and survival rate were observed in 30% protein feed. Meanwhile, moisture content was higher in fish fed with 30% CP feed while highest crude protein was recorded in 40% CP fed fish. Lowest fat content was observed in 32% CP feed. Amino acid profile of fish revealed better results in 30% CP feed. Total protein, glucose and globulin were also highest in fish feeding 30% CP feed, while albumin was highest in 40% CP feed. It is concluded that 30% CP feed showed better results in terms of growth, amino acid profile and serological parameters without effecting fish body composition.


Resumo O presente estudo teve como objetivo determinar o efeito de diferentes níveis de proteína sobre o crescimento, composição corporal, perfil de aminoácidos e sorologia de alevinos de Channa marulius. O experimento foi conduzido em dez happas instalados em tanques de terra, cada um abastecido com 10 peixes, por 90 dias. Quatro alimentos para peixes comerciais com níveis de 25%, 30%, 32% e 40% de proteína bruta (PB) foram dados aos peixes com 3% de seu peso corporal úmido três vezes ao dia. Os resultados do estudo revelaram que maior ganho de peso, taxa de conversão alimentar e taxa de sobrevivência foram observados em 30% de proteína alimentar. Enquanto isso, o conteúdo de umidade foi maior em peixes alimentados com 30% de PB, enquanto a proteína bruta mais alta foi registrada em peixes alimentados com 40% de PB. O menor conteúdo de gordura foi observado em rações com 32% de PB. O perfil de aminoácidos dos peixes revelou melhores resultados na ração com 30% de PB. Proteína total, glicose e globulina também foram maiores em peixes alimentados com ração com 30% de PB, enquanto a albumina foi mais alta com 40% de PB. Conclui-se que a ração com 30% de PB apresentou melhores resultados em termos de crescimento, perfil de aminoácidos e parâmetros sorológicos sem afetar a composição corporal dos peixes.

ABSTRACT

Abstract Soybean meal is an inexpensive plant origin protein which has been used in practical diets as a replacement of animal protein such as fish meal or chicken meal, due to the uneconomical price of animal protein diets. Consequently, a research study was conducted on some commercial species of Indian major carps i.e. Catla (Cattla cattla), Rohu (Labeo rohita) and Mrigala (Cirhinus mrigala) (Hamilton, 1822) to estimate optimum dietary protein requirement of soy bean meal in diet in an intensive polyculture. Three different diets (SBM I, SBM II and SBM III) were formulated by 80%, 50% and 20% replacement of fish meal with soybean meal from a 45% fish meal diet (control).Highest monthly mean weight gain was obtained by SBM II (with 35% CP and about 50% substitution of fish meal), while SBM III (45% Crude Protein and about 20% substitution of fish meal) was stood second. All tested diets respond enormously by producing high yield as compare to control diet, though SBM II generated highest yield among all. On the bases of the following research, it was revealed that the SBM can surrogate even50% fish meal without any augmentation of other amino acids in the diet of Indian major carps.


Resumo O farelo de soja é uma proteína de origem vegetal de baixo custo que tem sido usada em dietas práticas como um substituto da proteína animal, como farinha de peixe ou farinha de frango, devido ao preço não econômico das dietas com proteína animal. Consequentemente, um estudo/pesquisa foi realizado com algumas espécies comerciais de carpas principais indianas, ou seja, Catla (Cattla cattla), Rohu (Labeo rohita) e Mrigala (Cirhinus mrigala) (Hamilton, 1822), para estimar a necessidade ideal de proteína dietética de farelo de soja na dieta em uma policultura intensiva. Três dietas diferentes (SBM I, SBM II e SBM III) foram formuladas por 80%, 50% e 20% de substituição de farinha de peixe por farelo de soja de uma dieta de 45% de farinha de peixe (controle). O maior ganho de peso médio mensal foi obtido por SBM II (com 35% PB e cerca de 50% de substituição de farinha de peixe), enquanto SBM III (45% de proteína bruta e cerca de 20% de substituição de farinha de peixe) ficou em segundo lugar. Todas as dietas testadas respondem enormemente produzindo alto rendimento em comparação com a dieta controle, embora SBM II tenha gerado o maior rendimento entre todas. Com base na pesquisa a seguir, foi revelado que o SBM pode substituir até 50% da farinha de peixe sem qualquer aumento de outros aminoácidos na dieta das carpas principais indianas.

ABSTRACT

Abstract The study was conducted to evaluate the effect of Moringa olifera on the growth and gut health of Tilapia (Oreochromis niloticus). The feed having 30% crude protein was prepared as an experimental diet with 4%, 8% and 10% M. olifera leaf supplementation, respectively. The control diet was devoid of M. olifera leaves. The 10 weeks feeding trial was carried out on 60 fish in aquaria. Fish was fed @ 3% of body weight twice a day. Diet with the high level of inclusion of M. olifera leaves significantly increased the growth rate, Survival Rate (SR), Specific Growth Rate (SGR) and Feed Conversion Efficiency (FCE) in all treatment groups compared to the control group. Similarly, Feed Conversion Ratio (FCR) gradually decreased and found highly-significant. To check the gut health of the Tilapia, random samples were selected and dissected. Nutrient agar was used as culture media to check the growth of bacteria. Pour Plate Method was used for viable colonies count by colony counter. Through staining method, the different bacteria such as Escherichia coli, Salmonella, Shigella and Pseudomonas aeruginosa were identify abundantly in the intestine of control diet fish but less number present in treatment diets groups. These results showed that M. olifera leaves up to 10% of dietary protein can be used for Nile tilapia for significant growth and healthy gut microbiota of fish.


Resumo O estudo foi conduzido para avaliar o efeito da Moringa olifera no crescimento e saúde intestinal da tilápia (Oreochromis niloticus). A ração com 30% de proteína bruta foi preparada como dieta experimental com 4%, 8% e 10% de suplementação de folhas de M. olifera, respectivamente. A dieta controle foi desprovida de folhas de M. olifera. O ensaio de alimentação de 10 semanas foi realizado em 60 peixes em aquários. O peixe pesava 3% do peso corporal duas vezes ao dia. A dieta com alto nível de inclusão de folhas de M. olifera aumentou significativamente a taxa de crescimento, taxa de sobrevivência (SR), taxa de crescimento de sobrevivência (SGR) e eficiência de conversão alimentar (FCE) em todos os grupos de tratamento em comparação com o grupo de controle. Da mesma forma, a taxa de conversão de alimentação (FCR) diminuiu gradualmente e foi considerada altamente significativa. Para verificar a saúde intestinal da tilápia, amostras aleatórias foram selecionadas e dissecadas. O ágar nutriente foi usado como meio de cultura para verificar o crescimento das bactérias. O método da placa de Verter foi usado para a contagem de colônias viáveis ​​por contador de colônias. Através do método de coloração, diferentes como Escherichia coli, Salmonella, Shigella e Pseudomonas aeruginosa foram identificados abundantemente no intestino de peixes da dieta controle, mas em menor número nos grupos de dieta de tratamento. Esses resultados mostraram que M. olifera deixa até 10% da proteína dietética e pode ser usado para tilápia do Nilo para um crescimento significativo e microbiota intestinal saudável de peixes.

ABSTRACT

Abstract The present study aimed to evaluate the diet of the free-living crab-eating fox by identifying the stomach contents of the 17 crab-eating foxes (Cerdocyon thous) roadkilled in two conservation units, both located in the Amazon rainforest. The food items were quantified by frequency of occurrence (FO) and percentage of occurrence (PO). The stomach contents were analysed for dry matter (DM), crude protein (CP), crude fibre (CF), ether extract (EE), and mineral matter (MM). Nitrogen-free extractives (NFE), metabolisable energy (ME) values, as well as the energy need for maintenance were estimated. The composition of the diet for the crab-eating fox presented 29 food items from the different taxonomic groups, with a greater diversity of items of animal origin (n=22), although the highest frequency of occurrence was gramineae (Poaceae) (41.18%). Among the items of animal origin, 21% were mammals, 18% reptiles, 10% amphibians, 9% invertebrates and 3% birds. A high content of CF (62.76%) were determined. Nitrogen-free extractive and dry matter averages were 5.91% and 141.82 kcal/100g, respectively. The average maintenance energy was 447.01 kcal/day. These findings suggesting that the crab-eating foxes have a generalist diet with an omnivorous diet in the Amazon basin, feeding on gramineae, fruits, insects, snakes, amphibians, birds and small mammals and have the same feeding habit that present in other Brazilian biomes.


Resumo Este estudo objetivou analisar a dieta do cachorro-do-mato, de vida livre, por meio da identificação do conteúdo estomacal de 17 Cerdocyon thous atropelados em duas unidades de conservação da Floresta Amazônica. O conteúdo estomacal foi analisado e os itens alimentares foram quantificados pela frequência de ocorrência (FO) e percentagem de ocorrência (PO). Também foram avaliados os teores de matéria seca (MS), proteína bruta (PB), fibra bruta (FB), extrato etéreo (EE) e, matéria mineral (MM). Foram estimados o extrativo não-nitrogenado (ENN), a energia metabolizável (EM) e a necessidade energética de manutenção. A composição da dieta do cachorro-do-mato apresentou 29 itens alimentares dos diferentes grupos taxonômicos, tendo uma maior diversidade de itens de origem animal (n=22), ainda que a maior FO tenha sido de gramíneas (Poaceae) (41.18%). Dentre os itens de origem animal, 21% eram mamíferos, 18% répteis, 10% anfíbios, 9% invertebrados e 3% aves. Determinou-se um alto teor de FB (62.76%). A média do ENN e da MS foi 5.91% e 141.82 kcal/100g, respectivamente. A média da energia de manutenção foi 447.01 kcal/dia. Estes achados sugerem que o cachorro-do-mato encontrado na Bacia Amazônica é um animal generalista com uma dieta onívora, se alimentando de gramíneas, frutos, insetos, serpentes, anfíbios, aves e pequenos mamíferos, portanto com o mesmo hábito alimentar relatado a esta espécie quando encontrada em outros biomas brasileiros.

ABSTRACT

Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC's 7.97 ×103mm-3, RBC's 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.


Resumo O objetivo do presente estudo é avaliar os efeitos das nanopartículas de selênio no crescimento, hematologia e digestibilidade dos nutrientes de alevinos de Labeo rohita. Os alevinos foram alimentados com sete dietas isocalóricas à base de farinha de girassol suplementada com diferentes concentrações de nanopartículas, nomeando T1 a T7 (0, 0,5, 1, 1,5, 2, 2,5 e 3 mg / kg), com 5% do peso corporal úmido enquanto o óxido crômico foi usado como um marcador indigesto. Após a experimentação por 90 dias, o grupo tratado com T3 (nível 1mg / kg -1Se-nano) mostrou o melhor resultado em parâmetros hematológicos (WBC's 7,97 × 103mm-3, RBC's 2,98 × 106mm-3 e contagem de plaquetas 67), digestibilidade dos nutrientes (proteína bruta: 74%, extrato de éter: 76%, energia bruta: 70%) e desempenho de crescimento (ganho de peso 13,24 g, ganho de peso % 198, taxa de conversão alimentar 1,5, taxa de sobrevivência 100%) em comparação com os outros grupos de tratamento. As taxas de crescimento específicas foram encontradas significativamente mais altas em T5 do que em outros grupos. O presente estudo indicou efeito positivo de 1 mg / kg de nanopartículas de Se no avanço do crescimento, parâmetros hematológicos e digestibilidade de nutrientes de alevinos de L. rohita.

ABSTRACT

Abstract This study assessed the anthelminthic feed additive albendazole effect on the main indicators of the quality of sheep meat obtained from infected and deworming animals. A total of 20 heads of Akzhaik meat and wool sheep (i.e. 2 years of age, of different sex) were used in a 20-day experiment and 2 groups of 10 heads were formed (n = 4). The sheep were fed with the basic diet (i.e. control, group CON), without adding anything, and the second group was fed the basic diet orally with the addition of a dose of 1.2 g / head (an experimental group). At the end of the experiment, a control slaughter was carried out from each group in order to study the biochemical composition of meat and its quality. The anthelmintic feed additive albendazole did not have a significant effect on the indicators (organoleptic and physicochemical) of meat quality (P> 0.04). However, the ratio of fat and ash in the meat of the control group has differences in indicators and is reduced by 24.81% and 0.03%, respectively. The drug had a significant effect on the biological value of meat in the experimental group, where there is a higher content of essential amino acids (P = 0.06), nonessential (P = 0.05) concentrations in comparison with the CON groups. The results obtained show that the meat of the experimental groups of sheep, when using the anthelminthic feed additive albendazole, did not have a significant effect on organoleptic parameters, but significantly positively influenced the metabolism, live weight gain and biological value of meat.


Resumo Este estudo avaliou o efeito do aditivo anti-helmíntico albendazol sobre os principais indicadores de qualidade da carne ovina obtida de animais infectados e desparasitados. Um total de 20 cabeças de carne Akzhaik e ovelhas de lã (ou seja, 2 anos de idade, de sexo diferente) foi usado em um experimento de 20 dias e dois grupos de 10 cabeças foram formados (n = 4). As ovelhas foram alimentadas com dieta básica (ou seja, controle, grupo CON), sem adicionar nada, e o segundo grupo foi alimentado com dieta básica por via oral com a adição de uma dose de 1,2 g / cabeça (um grupo experimental). Ao final do experimento, foi realizado um abate controle de cada grupo para estudar a composição bioquímica da carne e sua qualidade. O aditivo anti-helmíntico albendazol não teve efeito significativo sobre os indicadores (organolépticos e físico-químicos) de qualidade da carne (P > 0,04). No entanto, a proporção de gordura e cinzas na carne do grupo de controle tem diferenças nos indicadores e é reduzida em 24,81% e 0,03%, respectivamente. A droga teve efeito significativo sobre o valor biológico da carne no grupo experimental, onde há maior teor de aminoácidos essenciais (P = 0,06), concentrações não essenciais (P = 0,05) em comparação com os grupos CON. Os resultados obtidos mostram que a carne dos grupos experimentais de ovinos, ao utilizar o aditivo anti-helmíntico albendazol, não teve efeito significativo nos parâmetros organolépticos, mas influenciou positivamente de forma significativa no metabolismo, ganho de peso vivo e valor biológico da carne.

ABSTRACT

The use of alternative nutritional sources is an important topic for animal production such as poultry. This study examined the effect of replacing soybean meal with sunflower leaf meal in the diet of laying shaver brown pullets. A total of 30 laying birds were assigned to three treatments of 0% (as control group), 10% and 15% MSFLM inclusion. Four eggs per replicate were randomly taken for three consecutive days at two weeks interval for five times, and 18 weeks individuals were selected after 40 days of experimental time. External parameters of the eggs (egg weight, egg length, egg breadth and egg shape index, shell thickness), and body parameters (Final body weight, weight gain), feed intake and hen day production were measured. For egg length, egg breadth and shell thickness showed significant difference (p< 0.05) in from the control birds. Final body weight, weight gain, feed intake and hen day production showed comparable results with values from eggs of birds on control diet. The study revealed the ability of birds to easily utilize the nutrients in the protein sources. MSFLM utilization up to 15% in pullets' diet revealed no detrimental effect on the performance of the laying birds and the external qualities of eggs produced.


O uso de fontes nutricionais alternativas é um tópico importante para a produção animal, como a avicultura. Este estudo examinou o efeito da substituição do farelo de soja por farelo de folha de girassol na dieta de frangas marrons barbeadoras poedeiras. Um total de 30 aves poedeiras foram designadas a três tratamentos de 0% (como grupo controle), 10% e 15% de inclusão MSFLM. Quatro ovos por repetição foram retirados aleatoriamente por três dias consecutivos em intervalos de duas semanas por cinco vezes, e indivíduos de 18 semanas foram selecionados após 40 dias do tempo experimental. Parâmetros externos dos ovos (peso do ovo, comprimento do ovo, largura do ovo e índice de forma do ovo, espessura da casca) e parâmetros corporais (peso corporal final, ganho de peso), consumo de ração e produção diária da galinha foram medidos. Para comprimento do ovo, largura do ovo e espessura da casca apresentaram diferença significativa (p <0,05) nas aves controle. Peso corporal final, ganho de peso, consumo de ração e produção de dia de galinha mostraram resultados comparáveis ​​com valores de ovos de aves em dieta controle. O estudo revelou a capacidade das aves de utilizar facilmente os nutrientes das fontes de proteína. A utilização de MSFLM até 15% na dieta das frangas não revelou nenhum efeito prejudicial no desempenho das aves poedeiras e nas qualidades externas dos ovos produzidos.

ABSTRACT

The demand for products to replace high-cost raw materials, such oil and fish meal, in the manufacture of feed for use in aquaculture, while also guaranteeing the nutritional quality of the diets, is increasing. Silage produced with fish and vegetables residues is a low-cost and efficient protein source. The objective of the present study was to evaluate the physiological and biochemical responses of tambaqui fingerlings fed four different levels of silage included in commercial feed with 28% crude protein, over two periods: 45 and 90 days. Each treatment was carried out over three replications, with 10 tambaqui in each 100 L experimental tank. At the end of each established period, blood samples were collected from five animals from each repetition to determine the hematological and biochemical variables. Body weight and total length, hepatosomatic and liposomal indices and hematocrit of specimens fed with diets supplemented with silage did not exhibit significant changes in both assessment period. After 45 days of feeding, the hemoglobin concentration increased when tambaqui were fed a diet including 20% silage. The red blood cell count, mean corpuscular volume and mean corpuscular hemoglobin did not change between treatments in either period. The total protein concentrations increased significantly in the plasma of tambaqui fed with diets with the inclusion of 5 and 10% of silage, evaluated after feeding for 45 days. It was found that the groups which had silage included in their diet did not exhibit significant alterations in the evaluated parameters, and the diet was therefore not consider harmful to the health of tambaqui. Therefore, the use of silage as a feed supplement during tambaqui farming is a sustainable alternative for producers, as it leads to a reduction of impacts of fish and vegetables waste disposal.


A procura por insumos que substituam produtos de alto custo, como óleo e farinha de peixe, na fabricação de rações para uso na aquicultura é crescente, sendo necessário garantir a qualidade nutricional das dietas. A silagem produzida a partir de resíduos de pescado e de vegetais apresenta-se como uma alternativa de baixo custo e eficiente fonte proteica. O objetivo do presente estudo foi avaliar as respostas fisiológicas e bioquímicas de alevinos de tambaqui alimentados com quatro níveis de inclusão de silagem em ração comercial com 28% de proteína bruta, em dois períodos: 45 e 90 dias. Cada tratamento foi realizado em três repetições, com 10 tambaquis em cada caixa experimental de 100 L. Ao término de cada período estabelecido, amostras sanguíneas foram coletadas de cinco animais de cada repetição para determinação das variáveis hematológicas e bioquímicas. Peso, comprimento total e índices hepatossomático e lipossomático de espécimes alimentados com silagem não mostraram alterações significativas em ambos os períodos de avaliação, bem como os valores de hematócrito. A concentração de hemoglobina de tambaqui após 45 dias de alimentação aumentou quando foi fornecida dieta com inclusão de 20% de silagem. A contagem de eritrócitos, volume corpuscular médio e hemoglobina corpuscular média não apresentaram alterações entre os tratamentos, em ambos os períodos. As proteínas totais aumentaram significativamente no plasma de tambaquis que receberam dietas com inclusão de 5 e 10% de silagem, avaliados após 45 dias de alimentação. Evidenciou-se que os grupos com inclusão de silagem na dieta não apresentaram alterações significativas nos parâmetros avaliados, assim não sendo prejudiciais à higidez do tambaqui. Portanto, o uso da silagem como suplemento alimentar durante o cultivo do tambaqui é uma alternativa sustentável para produtores, por promover a redução do descarte de resíduos de pescado e da agricultura.

ABSTRACT

Introdução:A menopausa é uma fase transitória entre o período reprodutivo para o período não fértil na vida da mulher, sendo dividido em três períodos: pré-menopausa, perimenopausa e pós-menopausa, podendo durar de 12 meses a 03 anos. Anutrição e a alimentação possuem um importante papel durante esse período, visando evitar ou minimizar problemas como: osteoporose, constipação, desidratação, hipertensão, ansiedade, diminuição da libido, depressão, alterações no sono, dores nas articulações e ganho de peso. Objetivo:Descrever os possíveis benefícios relacionados à nutrição durante o climatérioMetodologia:Revisão da literatura que utilizou as bases de dados Biblioteca Virtual em Saúde (BVS), National Library of Medicine (PubMed) e Scientific Electronic Library Online (Scielo), por meio dos Descritores em Ciência da Saúde (DeCS) "Diet", "Climacteric" combinados com o operador booleano AND. Nossa pesquisa considerou estudos originais publicados nos últimos cinco anos, tanto de acesso livre quanto restrito, sem restrição de idioma. Excluímos revisões, duplicatas e artigos não relacionados ao tema. Encontramos um total de 122 artigos com os descritores utilizados e selecionamos 19 para a amostra desta revisão. Resultados:Observou-se uma perda de peso significativa entreas mulheres no climatério, assim como ondas de calor em decorrência dos sintomas da menopausa. A compulsão alimentar dos grupos randomizados mostrou-se baixa bem como a pressão arterial. Pode-se constatar, ainda, que o IMC dessas mulheres apresentou declínio e os sintomas relacionados à depressão igualmente registraram uma redução. Conclusões:A intervenção nutricional no climatério resultou em benefícios significativos, incluindo perda de peso, redução dos sintomas da menopausa, melhora da saúde cardiovascular, diminuição do IMC e alívio dos sintomas relacionados à depressão. Esses resultados destacam a importância da nutrição como uma abordagem eficaz para melhorar a qualidade de vida das mulheres nessa fase de transição (AU).


Introduction:Menopause is a transitional phase between the reproductive and the non-fertile periods of women, divided into pre-menopause, perimenopause and post-menopause, lasting from 12 months to 3 years. Nutritionand diet play a relevant role, aiming to avoid or minimize problems such as osteoporosis, constipation, dehydration, hypertension, anxiety, decreased libido, depression, changes in the sleep cycle, joint pain, and weight gain. Objective:Describing the possible benefits related to nutrition during menopause. Methodology:AThis paper presents a literature review that used the Virtual Health Library (VHL), National Library of Medicine (PubMed) and Scientific Electronic Library Online (Scielo) databases, through the Health Science Descriptors (DeCS) "Diet", "Climacteric" combined with the Boolean operator AND. The research considered original studies published in the last five years, both of open and restricted access, without restrictions for languages. Reviews, duplicates and articles unrelated to the topic were excluded. A total of 122 articles were found using these descriptors, and 19 were selected for the sample of this review. Results:Significant weight loss was observed among climacteric women, as well as hot flashes due to menopausal vasomotor symptoms. Binge eating in the randomized groups was low, as was blood pressure. It was also observed that the BMI of these women showed a decline and symptoms related to depression were also reduced. Conclusions:A nutritional intervention during menopause resulted in significant benefits, including weight loss, reduced symptoms, improved cardiovascular health, decreased BMI, and relief of symptoms related to depression. The importance of nutrition is highlighted as an effective approach to improve the quality of life of women in this transition phase (AU).

ABSTRACT

Introducción. A nivel mundial los niños, niñas y adolescentes lideran el consumo de productos ultraprocesados. El objetivo de este trabajo fue caracterizar la ingesta de energía según el grado de procesamiento de los alimentos por grupo etario, en la población urbana mayor de 2 años de la Argentina. Población y métodos. Estudio transversal, con datos de la 2da Encuesta Nacional de Nutrición y Salud 2018-19, en una muestra probabilística polietápica de localidades urbanas de Argentina. A partir de la información recopilada con el recordatorio de 24 horas, se analizó la ingesta diaria de energía, para cada grupo etario, de 1) alimentos sin procesar o mínimamente procesados; 2) ingredientes culinarios procesados; 3) alimentos procesados, y 4) productos ultraprocesados. Se realizó análisis estadístico descriptivo. Resultados. En 15 444 individuos mayores de 2 años, los alimentos mínimamente procesados representaron el 34,5 % de la energía diaria; los productos ultraprocesados, el 26,0 %; los alimentos procesados, el 23,0 %, y los ingredientes culinarios, el 16,6 %. El porcentaje de energía aportada por ultraprocesados es mayor en niños, niñas y adolescentes que en los adultos (p <0,01), mientras que para alimentos procesados e ingredientes culinarios la tendencia es opuesta (p <0,01). Las galletitas, los amasados de pastelería, las bebidas azucaradas y las golosinas representaron dos tercios de la energía aportada por ultraprocesados. Conclusión. Los niños, niñas y adolescentes de entornos urbanos de la Argentina presentan la mayor ingesta de energía a partir de productos ultraprocesados. Las políticas alimentarias deben contemplar la situación de cada grupo etario para promover una alimentación más saludable.


Introduction. Worldwide, children and adolescents lead the consumption of ultra-processed foods. The objective of this study was to describe the energy intake by the degree of food processing by age group in the urban population over 2 years of age in Argentina. Population and methods. Cross-sectional study based on data from the 2nd National Survey on Nutrition and Health of 2018­2019 conducted using a multistage probability sample from urban areas of Argentina. Data were collected from a 24-hour recall and were analized, for each age group, the daily energy intake from 1) unprocessed or minimally processed foods; 2) processed culinary ingredients; 3) processed foods; and 4) ultra-processed foods. A descriptive, statistical analysis was performed. Results. In 15 444 individuals older than 2 years, minimally processed foods accounted for 34.5% of daily energy; ultra-processed foods, 26.0%; processed foods, 23.0%; and culinary ingredients, 16.6%. The percentage of energy from ultra-processed foods is higher in children and adolescents than in adults (p < 0.01), while the trend is the opposite from processed foods and culinary ingredients (p < 0.01). Cookies, pastries, sweetened beverage and confectionery accounted for two-thirds of the energy contributed by ultra-processed foods. Conclusion. Children and adolescents in urban areas in Argentina showed the highest energy intake from ultra-processed. Food policies should consider the characteristics of each age group to promote a healthier diet.

ABSTRACT

Introducción. El confinamiento debido a COVID-19 influenció el estilo de vida de la población mundial. En México, se ha reportado que esta influencia fue mayoritariamente negativa. Sin embargo, existen muy pocos estudios que reporten el impacto en poblaciones de alta marginación como el estado de Oaxaca, donde ya antes de la pandemia presentaban altas tasas de malnutrición. Objetivo. Analizar los efectos del aislamiento por COVID-19 sobre el consumo alimentario de la población del sur de México. Materiales y métodos. Estudio longitudinal, con una muestra (autoseleccionada) de adultos reclutados mediante un link a una página en LimeSurvey. El primer requisito fue el consentimiento informado. Se preguntaron datos sociodemográficos y se aplicó un cuestionario cuantitativo de frecuencia de consumo de alimentos (raciones/día) recomendables (carnes, cereales, leguminosas, verduras, frutas) y no recomendables (gaseosas, superfluos, azúcares y bebidas alcohólicas). Los participantes respondieron la encuesta al comienzo de la reclusión (marzo'2019) y en enero de 2021. Los datos se analizaron con SPSS'23. Resultados. Se observó un descenso significativo en el consumo de raciones/día (p<0.001) de carnes, cereales, leguminosas y verduras y por otro lado, el consumo de todos los alimentos no recomendables analizados (gaseosas, superfluos, azúcares y bebidas alcohólicas) aumentó significativamente (p<0.001). Conclusiones. Durante el aislamiento por COVID-19 la población oaxaqueña aumentó el consumo de alimentos no saludables y disminuyó el de saludables. Considerando que la situación de salud previa a la pandemia ya no era la esperada, estos resultados aportan un panorama alarmante que requiere intervención(AU)


Introduction. The isolation due to COVID-19 influenced the lifestyle of the world population. In Mexico, it was reported that this influence was mostly negative. However, there are few studies that report this impact in highly marginalized populations such as Oaxaca, which before the pandemic already had high malnutrition figures. Objective. To analyze the effects of isolation by COVID-19 on the food consumption of the population of southern Mexico. Materials and methods. Longitudinal study, with a (self-selected) sample of adults recruited through a link to a page in LimeSurvey. The first requirement was informed consent. Sociodemographic data were recolected and a quantitative questionnaire was applied on the frequency of consumption of recommended (meat, cereals, legumes, vegetables, fruits) and non-recommended (soda, miscellaneous group, sugar, and alcoholic beverages) foods (servings/ day). The participants answered the survey at the beginning of the isolation (March'2019) and in January 2021. The data was analyzed with SPSS'23. Results. A significant decrease was observed in the consumption of servings/day (p<0.001) of meat, cereals, legumes and vegetables and on the other hand, the consumption of all non-recommended foods analyzed (soda, miscellaneous group, sugar and alcoholic beverages) increased exponentially (p<0.001). Conclusions. During the isolation due to COVID-19, the Oaxacan population increased the consumption of unhealthy foods and decreased that of healthy ones. Considering that the health situation prior to the pandemic was no longer as expected, these results provide an alarming panorama that requires intervention(AU)

ABSTRACT

Introducción. La producción de alimentos es una de las principales causas de Emisiones de Gases de Efecto Invernadero (GEI). Estimar las emisiones GEI de la dieta es el punto de partida para definir dietas saludables y sostenibles con el ambiente. Objetivo. Estimar el total GEI de la dieta de mujeres adolescentes del oriente de Guatemala, así como la contribución de grupos de alimentos a este valor. Materiales y métodos. En el contexto de un estudio de agricultura y nutrición en el oriente de Guatemala, se realizó un análisis secundario de los datos dietéticos (Recordatorio de 24 horas) de 2082 mujeres adolescentes. Los alimentos reportados fueron enlazados con la base de datos SHARP, que contiene estimaciones de GEI para 944 alimentos. La variable de enlace fue un código único armonizado con el sistema de clasificación FoodEx2. Resultados. La dieta es poco diversa, principalmente a base de grupos de alimentos de origen vegetal, con poca presencia de alimentos de origen animal. El GEI de la dieta fue de 2,3 Kg CO2 eq/ per cápita/día, con la mayor contribución de comidas preparadas (26,7%) y panes, tortillas y similares (12,8%). Conclusiones. La dieta de las mujeres adolescentes de áreas rurales de Guatemala tiene un GEI inferior al reportado en otros países de la región para estratos socioeconómicos con mayor consumo de alimentos de origen animal. Este estudio es el punto de partida para sistematizar la metodología para continuar con las estimaciones de GEI en Guatemala(AU)


Introduction. Food production is one of the main causes of Greenhouse Gas Emissions (GHGE). Estimating GHG emissions from the diet is the starting point for defining healthy and environmentally sustainable diets. Objective. Estimate the total GHGE in the diet of adolescent women from eastern Guatemala, as well as the contribution of food groups to this value. Materials and methods. In the context of an agriculture and nutrition study in eastern Guatemala, a secondary analysis of dietary data (24-hour recall) of 2082 adolescent women was performed. The reported foods were linked to the SHARP database, which contains GHGE estimates for 944 foods. The linking variable was a unique code harmonized with the FoodEx2 classification system. Results. The diet is not diverse, mainly based on food groups of plant origin, with little presence of foods of animal origin. The GHG of the diet was 2.3 Kg CO2 eq/per capita/day, with the greatest contribution from prepared foods (26.7%) and breads, tortillas and similar products (12.8%). Conclusions. The diet of adolescent women in rural areas of Guatemala has a lower GHG than that reported in other countries in the region for socioeconomic strata with greater consumption of foods of animal origin. This study is the starting point to systematize the methodology to continue with GHG estimates in Guatemala(AU)

ABSTRACT

Introduction. The COVID-19 pandemic has impacted diet quality in differentways. In this context, community, organizational and consumer nutrition environments can influence the eating pattern. Objective. The purpose of this study was to identify how quarantine during the COVID-19 pandemic changed the diet in Brazil. Materials and methods. A natural experiment organized into experimental (social-isolated group - SIG) and control groups (non-isolated group - CG) was conducted with data collection from an online survey at the beginning of the pandemic (T0) and in the less restrictive period of 2020 (T1). Pre-post improvements in diet quality (IDQ) were determined for the SIG and CG. Intro-intergroup changes were tested using the Mann­Whitney and Wilcoxon signed rank tests. The intervention effect was estimated using crude and adjusted difference- indifference in multilevel regression analysis accounting for repeated measures. Results. A sample of 565 Brazilian adults answered the questionnaire at T0 and T1. IDQ was favored twice or more by attitudes such as buying food directly from farmers/street markets, reducing requests for food delivery, and increasing time spent on eating activities and the frequency of cooking. The isolated group had no IDQ at T1, whereas the no isolated group, who worsened diet quality (6.1%) at T0, improved it at T1 (4.8%). Conclusions. The restrictive quarantine forced the non-isolated population to have an experience comparable to a food desert, negatively affecting their diet(AU)


COVID-19 ha impactado la calidad de la dieta de diferentes maneras. Los entornos comunitarios, organizacionales y nutricionales de los consumidores pueden influir en los patrones dietéticos. Objetivo. el objetivo de este estudio fue identificar cómo la cuarentena durante la pandemia de COVID-19 cambió la dieta en Brasil. Materiales y métodos. Se realizó un experimento natural organizado en grupos experimental (grupo socialmente aislado - SIG) y control (grupo no aislado - GC) con datos recolectados en una encuesta en línea al inicio de la pandemia (T0) y en el momento menos restrictivo de 2020 (T1). Se determinaron mejoras pre-post en la calidad de la dieta (IDQ) para SIG y GC. Los cambios intra-intergrupo se probaron utilizando las pruebas de rangos con signos de Mann-Whitney y Wilcoxon. El efecto de la intervención se estimó utilizando diferencias crudas y ajustadas en el análisis de regresión multinivel, teniendo en cuenta medidas repetidas. Resultados. Una muestra de 565 adultos brasileños respondió el cuestionario en T0 y T1. IDQ se vio favorecido dos o más veces por actitudes como comprar alimentos directamente de los agricultores/mercados callejeros, reducir los pedidos de entrega de alimentos y aumentar el tiempo dedicado a las actividades alimentarias y la frecuencia de cocinar. El grupo aislado no mostró IDQ en T1, mientras que el grupo no aislado, que tenía peor calidad de la dieta (6,1%) en T0, mejoró en T1 (4,8%). Conclusiones. La cuarentena restrictiva obligó a la población no aislada a tener una experiencia comparable a un desierto alimentario, afectando negativamente su dieta(AU)

ABSTRACT

Introducción: Hoy en día las enfermedades no transmisibles constituyen un grave problema que afecta el estado de salud de la población, con una tendencia ascendente preocupante. Objetivo: Identificar los factores predisponentes a las enfermedades no transmisibles en pacientes de un área de salud. Métodos: Se realizó un estudio observacional, descriptivo y transversal de 286 individuos, escogidos a través de un muestreo aleatorio bietápico en el área de salud Josué País García del municipio de Santiago de Cuba, durante el 2021. Las variables analizadas fueron antecedentes patológicos personales, consumo de productos del tabaco y alcohol, hábitos dietéticos y evaluación nutricional. Se utilizaron como medidas de resumen las frecuencias absolutas, el porcentaje y la tasa de prevalencia para variables cualitativas; la media aritmética y el mínimo e intervalo de confianza para variables cuantitativas. Resultados: El mayor riesgo de presentar hipertensión arterial figuró en las féminas (35,6 %) y existió alta prevalencia de fumadores en hombres (30,5 %) y mujeres (27,7 %). Asimismo, predominaron la exposición al humo de tabaco (fumadores pasivos) y el consumo de alcohol en edades tempranas (25-34 años). De los encuestados, 33,3 % resultó estar sobrepeso u obeso. Conclusiones: Los factores predisponentes a las enfermedades no transmisibles pudieran estar asociados con estilos de vida no saludables como el consumo de productos del tabaco y el alcohol, los hábitos dietéticos inadecuados y el sobrepeso.


Introduction: Nowadays non-communicable diseases are a serious problem that affects the health of the population, with a worrying upward tendency. Objective: To identify the predisposing factors to non-communicable diseases in patients from a health area. Methods: An observational, descriptive and cross-sectional study of 286 individuals, chosen by a two-stage random sampling in Josué País García health area from Santiago de Cuba municipality, was carried out during 2021. The analyzed variables were personal pathological history, consumption of tobacco and alcohol products, dietary habits and nutritional evaluation. The absolute frequencies, percentage and prevalence rate were used as summary measures for qualitative variables; the arithmetic mean and the minimum and interval of confidence were used for quantitative variables. Results: The highest risk of presenting hypertension was in females (35.6%) and there was a high prevalence of smokers in men (30.5%) and women (27.7%). Also, the exposure to tobacco smoke (passive smokers) and alcohol consumption at an early age (25-34 years) prevailed. Of those interviewed, 33.3% was overweight and obese. Conclusions: The predisposing factors to non-communicable diseases could be associated with the non healthy lifestyle as the consumption of tobacco and alcohol products, inadequate dietary habits and overweight.

ABSTRACT

Introduction:Metabolic syndrome (MetS) predicts cardiovascular disease, and patients with this condition and type 2 diabetes have increased albuminuria, significantly impacting cardiovascular mortality and kidney disease progression. A considerable number of interventions to control MetS exist and are considered efficient, including the use of medication and changes in lifestyle. However, which approaches are effective in controlling albuminuria remains unclear. This systematic review protocol aims to map in the available literature whether lifestyle, medication, and surgical intervention for MetS have an impact on reducing albuminuria in adult patients. Methods: The Joanna Briggs Institute methodology for systematic reviews will be followed. Cochrane Database of Systematic Reviews, Scopus, Embase, and MEDLINE/PubMed databases will be used. For the Gray Literature, the DART-Europe E-theses Portal. There will be no language restriction. Studies written after 2009 will be included due to the consensus and definition of metabolic syndrome. This review will include studies considering pharmacological and non-pharmacological treatments for controlling albuminuria in patients with MetS. Studies where MetS is described in children and adolescents, animals, pregnant women, and patients with type 1 diabetes will be excluded. First, the selection will be based on reading the title and summary of the texts retrieved in the search strategy, followed by reading the relevant texts in full by two reviewers. After the selection of the studies, the extraction of the data, analysis, and synthesis will be conducted according to the JBI methodology

ABSTRACT

SUMMARY: The aim of this cross-sectional study was to compare dietary intake to published recommendations and to analyze the potential relationship between body composition and dietary intake in collegiate athletes. Eighteen healthy male middle- and long- distance runners (age 20.11 ± 2.72 y; height, 174.7 ± 6.1 cm; body mass, 64.0 ± 7.7 kg), were recruited from a Mexican university track and field team at the beginning of the general preparation phase for national competitions. Participants completed three 24-hour dietary recalls, which were used to estimate dietary intake. Body composition was measured by Dual-energy X-ray absorptiometry (DXA). Athletes displayed high body fat values. Protein intake was significantly higher than published recommendations. Iron, zinc, sodium, and vitamin C intake were significantly higher than recommended values, while potassium and calcium intake were below established recommendations. No significant correlations between body composition variables (i.e body fat, lean body mass, bone mineral content) and dietary intake (i.e energy, macronutrients and selected vitamins and minerals) could be found. These findings suggest that coaches and practitioners should pay close attention to dietary intake and body composition of endurance athletes starting general preparation for competition. Future studies on changes of dietary intake and body composition during off-season and competitive phase, which also track physical activity, are warranted.


El objetivo de este estudio transversal fue comparar la ingesta dietética con las recomendaciones publicadas y analizar la relación potencial entre la composición corporal y la ingesta dietética en corredores universitarios. Dieciocho atletas masculinos sanos de media y larga distancia (edad 20,11 ± 2,72 años; altura, 174,7 ± 6,1 cm; masa corporal, 64,0 ± 7,7 kg), fueron reclutados de un equipo de atletismo de una universidad mexicana al comienzo de la fase de preparación general de competiciones nacionales. Los participantes completaron tres recordatorios dietéticos de 24 horas, que se utilizaron para estimar la ingesta dietética. La composición corporal se midió mediante absorciometría de rayos X de energía dual (DXA). Los atletas mostraron altos valores de grasa corporal. La ingesta de proteínas fue significativamente mayor que las recomendaciones publicadas. La ingesta de hierro, zinc, sodio y vitamina C fue significativamente superior a los valores recomendados, mientras que la ingesta de potasio y calcio estuvo por debajo de las recomendaciones establecidas. No se encontraron correlaciones significativas entre las variables de composición corporal (es decir, grasa corporal, masa corporal magra, contenido mineral óseo) y la ingesta dietética (es decir, energía, macronutrientes y vitaminas y minerales seleccionados). Estos hallazgos sugieren que los entrenadores y los practicantes deberían prestar mucha atención a la ingesta dietética y la composición corporal de los atletas de resistencia que comienzan la preparación general para la competencia. Se justifican estudios futuros sobre los cambios en la ingesta dietética y la composición corporal durante la fase fuera de temporada y competitiva, como también un seguimiento de la actividad física.

ABSTRACT

Non-Alcoholic Fatty Liver disease (NAFLD) can lead to Non Alcoholic steatohepatitis (NASH), cirrhosis, and liver cancer. The treatment for NAFLD involves modification of caloric intake and physical activity. NAFLD has a pro-oxidant nature; therefore, it is logical to suppose that the antioxidant methionine can be used as a treatment for this disease. Aim. This study aimed to evaluate the effect of high-methionine dietary therapy on patients with NAFLD. Materials and methods. A randomized clinical study was conducted over three months. In this study, 121 NAFLD patients participated, and the age of the participants was ≥ 20 years (experimental group included 56 and control group 65), all of whom were randomized and matched by sex, recluted from the ISSSTE hospital in Xalapa, Mexico. The patients were instructed to consume food to cover the recommended methionine daily doses, and the daily amount consumed was calculated. Methionine effect was measured as NAFLD regression and quality of life improvement. Results. Nutritional therapy induced NAFLD regression and diminished central fat accumulation, blood pressure, and the fatty liver index. Some parameters, such as liver enzymes, did not changed. The quality of life of patients improved after treatment. Conclusions. In this study, we show a hepatoprotective effect induced only in three months of chances in the diet, thus, a longer diet may generate more relevant benefits in the resistant parameters of our study(AU)


La enfermedad del hígado graso no alcohólico (NAFLD) puede conducir a la esteatohepatitis no alcohólica (NASH), la cirrosis y el cáncer de hígado. El tratamiento para NAFLD es la modificación de la ingesta calórica y la actividad física. Debido a que NAFLD tiene una naturaleza pro-oxidante; es lógico suponer que el antioxidante metionina puede utilizarse en el tratamiento de esta enfermedad. Objetivo. el presente trabajo evaluó el papel de la terapia nutricional con alimentos ricos en metioninaen pacientes con NAFLD. Materiales y Métodos. Se realizó un ensayo clínico aleatorizado durante tres meses. Participaron en el estudio 121 pacientes con NAFLD con edad ≥ 20 años (56 en el grupo experimental y 65 en el control), todos aleatorizados y pareados por sexo, reclutados de la Clínica Hospital ISSTE en la ciudad de Xalapa, México, en el año 2015. Se instruyó a los pacientes en consumir los alimentos hasta completar la dosis diaria recomendada de metioninay se calculó la cantidad diaria consumida. Su efecto se midió como la regresión de NAFLD y la mejora de la calidad de vida. Resultados. La terapia nutricional retrocedió NAFLD; disminuyó la acumulación de grasa central, la presión arterial y el índice de hígado graso. Algunos parámetros, como las enzimas de la función hepática, no se modificaron con el tratamiento. Otro parámetro fue la mejora de la calidad de vida de los pacientes tratados. Conclusiones. En este trabajo mostramos un impacto hepatoprotector producido con tan solo tres meses de cambios en la dieta, por lo que una dieta más prolongada podría generar beneficios aún más significativos en los parámetros resistentes en nuestro protocolo(AU)
