Pediatric inflammatory multisystemic syndrome in Brazil: sociodemographic characteristics and risk factors to death

Abstract Objective: To determine the incidence of MIS-C in Brazil, describe the clinical and sociodemographic characteristics of the pediatric population affected by MIS-C and compare mortality and lethality outcomes with isolated Covid-19 and MIS-C cases. Methods: Observational and retrospective cohort study of cases of MIS-C associated with Covid-19 in the Brazilian population between 04/01/2020 and 04/17/2021. Data from the Ministry of Health's epidemiological bulletin up to the 15th epidemiological week of 2021, were used. The analyzes were descriptive through absolute and relative frequencies. The significance level is 5% in Stata 16.0 package. Results: Between 04/01/2020 and 04/07/2021, 903 cases of MIS-C associated with Covid-19 were notified in Brazil, of which, the largest part (55.26%) were male, between 0 and 4 years old (45.29%), from the Southeast region (38.76%). The deaths (61; 6.7%) were higher in the female gender, between 0 and 4 years old (47.54%) and in the Southeast region (34.43%). It was identified that the risk of death by MIS-C related to Covid-19 is 5.29 (CI = 2.83; 9.87 and P-value = <0.001) times higher in adolescents from 15-19 years old than in other age groups when compared to 0-4 years old children. Also, the residency in North region was as risk factor to death (RR = 3.72, IC = 1.29; 10.74 e P-value = 0.008). Conclusion: In this study, despite the numbers showing more deaths from zero to 4 years old, the risk for teenagers is notably higher. In addition, Brazil's Northern region is a risk factor that reaffirms social inequality and poor access to health.

Orange peel silage in lamb feeding improves meat fatty acid profile / Silagem de bagaço de laranja na alimentação de cordeiros melhora o perfil de ácidos graxos da carne

Considering its nutritional quality and low cost compared to traditional foods, the orange peel has been used to replace grains in ruminant diets. This research was developed to evaluate the fatty acid profile of meat from lambs finished with diets containing orange peel silage (OPS) in replacement of corn (0, 33, 66 and 100%). Twenty Santa Inês lambs (five replicates per treatment), approximately five months old and body weight of 25.37 ± 1.94 kg, were distributed in a completely randomized design and the data obtained compared by the Tukey test at 0.05 of significance. There was a linear increase in the concentration of fatty acid capric (P = 0.026) and a quadratic increase for palmitic, palmitoleic, stearic, oleic, linoleic, conjugated linoleic (CLA) and α-linolenic acid, saturated, unsaturated, monounsaturated, polyunsaturated, Σn-6, Σn-3 fatty acids and desirable fatty acids in the meat of lambs fed with OPS (P<0.05). The replacement of corn by OPS in 66% in the diet of finishing lambs improves the fatty acid profile of the meat.

Considerando sua qualidade nutricional e baixo custo em relação aos alimentos tradicionais, a casca de laranja vem sendo utilizada em substituição aos grãos na dieta de ruminantes. Esta pesquisa foi desenvolvida para avaliar o perfil de ácidos graxos da carne de cordeiros terminados com dietas contendo silagem de bagaço de laranja (SBL) em substituição ao milho (0, 33, 66 e 100%). Vinte cordeiros Santa Inês (cinco repetições por tratamento), com aproximadamente cinco meses de idade e peso corporal de 25,37 ± 1,94 kg, foram distribuídos em um delineamento experimental inteiramente casualizado e os dados obtidos comparados pelo teste Tukey a 0,05 de significância. Houve aumento linear na concentração do ácido graxo cáprico (P = 0,026) e de forma quadrática (P<0,05) para o palmítico, palmitoleico, esteárico, oleico, linoleico, linoleico conjugado (CLA) e α-linolênico; dos ácidos graxos saturados, insaturados, monoinsaturados, poliinsaturados, Σn-6, Σn-3 e dos ácidos graxos desejáveis na carne de cordeiros alimentados com SBL. A substituição do milho pela SBL em 66% na dieta de cordeiros em terminação melhora o perfil de ácidos graxos da carne.

Treatment of experimentally induced partial-thickness burns in rats with different silver-impregnated dressings.

PURPOSE: To evaluate the morphometric, macroscopic and microscopic aspects of experimentally induced partial-thickness burns in rats treated with different silver-based dressings. METHODS: Wistar rats were used, divided into six treatments: saline (NaCl 0.9%); silver sulfadiazine 1%; Silvercel; Mepilex Ag; Aquacel Ag and Acticoat. The animals were monitored daily and euthanized at 7, 14 and 30 days after injury induction (DAI). RESULTS: At 7 DAI, necrosis/crust was greater in control, silver sulfadiazine and Mepilex Ag treatments, granulation tissue was induced by Aquacel Ag, polymorphonuclear infiltrate (PMN) infiltration was intensified by Mepilex Ag; mononuclear infiltrate (MN) infiltration and angiogenesis were increased by Silvercel. At 14 DAI, hemorrhage was decreased by Silvercel and Mepilex Ag, PMN infiltration increased by Acticoat. At 30 DAI, angiogenesis was greater in the Acticoat treatment and fibroblasts were increased by Acticoat and Mepilex Ag. Collagen was induced at 14 DAI by silver sulfadiazine and Aquacel Ag and, at 30 DAI, by silver sulfadiazine and Silvercel treatments. CONCLUSIONS: Silvercel and Acticoat presented better results than the other products. However, all the dressings were better than the control at some point during the process, and may contribute to the healing of partial thickness burns. Silvercel and Aquacel Ag treatments induced better cosmetic outcomes regarding wound closure and scarring.

Trends in bariatric surgeries in the Brazilian Federative Units, 2009-2019: a descriptive study.

OBJECTIVE: our objective is to describe the epidemiological distribution of hospitalizations and postoperative deaths, as well as the trends of bariatric surgeries performed by SUS in all Brazilian federative units (FUs) from an analysis of the period from 2009 to 2019. METHODS: This is an observational, descriptive ecological time-series study with quantitative and descriptive analysis, based on secondary data. The period analyzed was from 2009 to 2019. We collected, from DATASUS, data from obese men and women who were hospitalized after undergoing bariatric surgery. Prais-Winsten regression was performed to identify the trends. RESULTS: In the period, 83,829 bariatric surgeries were performed, of which 161 resulted in death, representing 0.19% of the procedures. We found an increasing trend in the number of surgeries for Brazil (ß=0.04; p<0.001), but 11 FUs showed a stationary trend and three, decreasing ones (six UFs did not have enough data to enter the analysis). In the North and Northeast regions, stationary trends prevailed, while in the Center-West, the decreasing trends, and in the South and Southeast, the increasing ones. CONCLUSIONS: we found an evident disparity between regions, suggesting deficiencies in access to health. By demonstrating which FUs and demographic characteristics have the lowest rates of surgeries, our study is able to direct public policies towards a more egalitarian Brazilian public health.

RESUMO Objetivo: nosso objetivo é descrever a distribuição epidemiológica das internações e óbitos pós-operatórios, bem como as tendências das cirurgias bariátricas realizadas pelo SUS em todas as unidades federativas (UFs) brasileiras a partir de uma análise do período de 2009 a 2019. Métodos: trata-se de um estudo observacional descritivo ecológico de série temporal com análise quantitativa e descritiva, com base em dados secundários. O período analisado foi de 2009 a 2019. Coletamos, no DATASUS, dados de homens e mulheres que possuem obesidade e foram internados após terem sido submetidos à cirurgia bariátrica. A regressão de Prais-Winsten foi utilizada para identificar as tendências. Resultados: no período, 83.829 cirurgias bariátricas foram realizadas, tendo 161 evoluído para óbitos, o que representa 0,19% dos procedimentos. Encontramos uma tendência crescente no número de cirurgias para o Brasil (β=0,04; p<0,001), mas 11 UFs apresentaram tendência estacionária e três, decrescente (seis UFs não tinham dados suficientes para entrar na análise). Nas regiões Norte e Nordeste prevaleceram tendências estacionárias, enquanto no Centro-Oeste, as decrescentes, e no Sul e Sudeste, as crescentes. Conclusões: encontramos uma evidente disparidade entre as regiões, sugerindo deficiências de acesso à saúde. Ao demonstrar quais UFs e características demográficas apresentam menores índices de cirurgias, nosso estudo é capaz de direcionar políticas públicas para uma saúde pública brasileira mais igualitária.

Mathematical models to adjust the parameters of in vitro cumulative gas production of diets containing preserved Gliricidia / Modelos matemáticos para ajuste dos parâmetros de produção cumulativa de gás in vitro de dietas contendo Gliricídia conservada

This study examined the use of the Gompertz, Groot, monomolecular, Richards and two-compartment-logistic mathematical models to investigate the kinetics of in vitro gas production of diets composed of combinations of Gliricidia hay or silage. In addition, the effects of Gliricidia hay or silage inclusion on the in vitro cumulative gas production of these diets were evaluated. Rumen fermentation kinetics were analyzed by the in vitro cumulative gas production methodology. The model parameters were estimated using the Gauss Newton method, with the exception of the Richards model, which was used by Marquardts algorithm. Model fit was assessed using the determination coefficient, F test for parameters identity, concordance correlation coefficient, root mean square error of prediction, and decomposition of mean square error of prediction into mean error, systematic bias and random error. The models were compared for accuracy (pairwise mean square error of prediction) and precision (delta Akaikes information criterion). All model evaluation and comparison statistics were calculated using Model Evaluation System software version 3.2.2. The Groot and Richards models did not differ from each other (P>0.05) and were the most precise and accurate (P<0.05). Therefore, the Groot model was selected due to its better accuracy and precision and easier access to the parameters. The inclusion of Gliricidia silage in the diet resulted in an increase in the time to obtain the maximum rate of degradation and in the time after incubation when half of the asymptotic level was reached. The Groot model is recommended to estimate the average curve. Dietary inclusion of Gliricidia silage alters the gas production curve due to the longer time required for the diet to reach the maximum rate of degradation, this can increase the time the diet remains in rumen and promote a reduction in the consumption.(AU)

[High-risk clusters and temporal trends in congenital syphilis infection in Brazil]. / Aglomerados de alto risco e tendência temporal da sífilis congênita no Brasil.

OBJECTIVE: To determine the occurrence of high-risk clusters for congenital syphilis (CS) in Brazil and describe the temporal trends in the CS infection in the country, comparing children whose mothers received vs. those whose mothers did not receive prenatal care. METHOD: This ecological study used data from the National Disease Notification System (Sistema de Informação de Agravos de Notificação, SINAN) and the Live Birth Information System (Sistema de Informações sobre Nascidos Vivos, SINASC). For cluster analysis, the Kulldorff scan statistic was applied to the population at risk. Statistical significance was determined by the log-likelihood ratio based on Poisson discrete distribution. To analyze the temporal trends of disease detection rates, Prais-Winsten regression was used. The analysis was performed with SatScan 9.4 and Stata 14.0 software. RESULTS: Clusters with detection rates of 41.3, 44.4 and 188.1 CS cases/10 000 live births were identified in 2001, 2009 and 2017 respectively. In 2001, the rates were 8 times higher in the clusters than in the remaining country; in 2009, the rates were 3.3 times higher; and in 2017, 2.5 times higher. An increasing trend in CS infection was detected in all regions and federation units. The rates were 8.53 times higher in the children of mothers without prenatal care (243.3 cases/1 000 live births vs. 28.3 cases/1 000 live births in the children of mothers with prenatal care). CONCLUSIONS: The identification of municipality clusters at high risk for CS and of increasing trends in CS infection across the country, even in the presence of prenatal care, suggests the need for improvement of public health actions to fight this disease.

Aglomerados de alto risco e tendência temporal da sífilis congênita no Brasil

[RESUMO]. Objetivo. Determinar a existência de aglomerados de municípios (clusters) com alto risco para sífilis congênita (SC) no Brasil e descrever a tendência temporal da doença no país, comparando a população de crianças cujas mães realizaram o pré-natal com aquelas cujas mães não realizaram esse controle. Métodos. Este estudo ecológico utilizou dados do Sistema de Informação de Agravos de Notificação (SINAN) e do Sistema de Informações sobre Nascidos Vivos (SINASC). Para a análise de aglomerados, a estatística de varredura Kulldorff foi aplicada à população de risco. A significância estatística foi determinada pelo logaritmo da razão de verossimilhança utilizando a distribuição discreta de Poisson. Para a análise das tendências das taxas de detecção do agravo, utilizou-se a regressão de Prais-Winsten. A análise foi realizada com os programas SatScan 9.4 e Stata 14.0. Resultados. Clusters com taxas de detecção de 41,3, 44,4 e 188,1 casos/10 000 nascidos vivos foram identificados em 2001, 2009 e 2017, respectivamente. Em 2001, as taxas foram 8 vezes maiores nos clusters do que no restante do país; em 2009, foram 3,3 vezes maiores; e, em 2017, 2,5. Detectou-se uma tendência crescente na infecção por SC em todas as regiões e unidades da federação. As taxas foram 8,53 vezes maiores nos neonatos cujas mães não realizaram pré-natal (243,3 casos/1 000 nascidos vivos vs. 28,4 casos/1 000 nascidos vivos em mães com pré-natal). Conclusões. A identificação de aglomerados de municípios com alto risco para SC e de tendências crescentes de infecção por SC em todo o país, mesmo na presença de pré-natal, indicam a necessidade de melhoria nas ações de saúde pública para o combate dessa doença.

Internações e custos hospitalares por quedas em idosos brasileiros / Hospitalizations and hospital costs due to falls in Brazilian elderly

Objetivos: verificar o número e as causas de hospitalizações por quedas em idosos brasileiros, além dos gastos federais do Sistema Único de Saúde (SUS), no período de 2000 a 2018. Métodos: trata-se de um estudo ecológico, utilizando informações disponíveis na base de dados do Departamento de Informática do SUS. Foram coletados dados de idosos (≥60 anos) que internaram no SUS devido às quedas no período de 2000 a 2018 no Brasil. Extraíram-se o número de hospitalizações no País e nas regiões (Norte, Nordeste, Sul, Sudeste e Centro-Oeste), as causas das quedas (Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde ­ 10) e o valor de gastos federais. Para fins estatísticos, utilizou-se análise descritiva. Resultados: totalizaram-se 1,48 milhões de hospitalizações por quedas em idosos no Brasil, com uma taxa de 38,6 a cada 10 mil. As principais causas desses registros no DATASUS foram as "quedas sem especificações", as "outras quedas no mesmo nível" e as "quedas no mesmo nível por escorregão, tropeção ou passos em falsos". Em relação às localidades, os idosos pertencentes às regiões Sudeste (47,1), Sul (44,1) e Centro-Oeste (40,4) foram aqueles que apresentaram maiores medianas das taxas de hospitalizações por quedas no período analisado. Entretanto, o Nordeste (variação%=0,4), o Sul (variação%=0,2) e o Centro-Oeste (variação%=0,2) demonstraram maiores elevações desse indicador ao longo dos 18 anos, enquanto apenas a região Norte apresentou redução (variação%=-0,5). A mediana de gastos hospitalares federais (milhões) foi de R$135,58, variando de R$112,89 até R$194,98. Conclusões: houve aumento das taxas de hospitalizações por quedas em idosos no SUS em quase todas as unidades federativas. As causas mais frequentes foram as "quedas sem especificações", as "outras quedas no mesmo nível" e as "quedas no mesmo nível por escorregão, tropeção ou passos em falsos". Além disso, ocorreu elevação dos gastos hospitalares federais ao longo do período no País.

Aims: to verify the number and causes of hospitalizations for falls in Brazilian elderly, in addition to the federal expenses of the Unified Health System (SUS), in the period from 2000 to 2018. Methods: this is an ecological study, using information available in the database of the SUS Department of Informatics. Data were collected from elderly (≥60 years) who were admitted to SUS due to falls in the period from 2000 to 2018 in Brazil. The number of hospitalizations in the country and in the regions (North, Northeast, South, Southeast and Midwest), the causes of falls (International Statistical Classification of Diseases and Related Health Problems ­ 10) and the amount of federal spending were extracted. For statistical purposes, descriptive analysis was used. Results: there were 1.48 million hospitalizations for falls in the elderly in Brazil, with a rate of 38.6 per 10,000. The main causes of these records in DATASUS were "falls without specifications", "other falls on the same level" and "falls on the same level due to slips, trips or false steps". Regarding the locations, the elderly belonging to the Southeast (47.1), South (44.1) and Midwest (40.4) regions were those who had the highest median hospitalization rates for falls in the analysed period. However, the Northeast (variation%=0.4), the South (variation%=0.2) and the Midwest (variation%=0.2) showed greater increases in this indicator over the age of 18, while only the North region showed a reduction (variation%=-0.5). The median federal hospital expenses (million) was R$135.58, ranging from R$112.89 to R$194.98. Conclusions: there was an increase in hospitalization rates due to falls in the elderly in SUS, in almost all federative units. The most frequent causes were "falls without specifications", "other falls on the same level" and "falls on the same level due to slips, trips or false steps". In addition, there was an increase in federal hospital spending over the period in the country.

CONCLUSION: rates of hospitalization for ACSCC and heart failure decreased, however rates for hypertension, angina and cerebrovascular diseases remained constant.

Desenvolvimento e fisiologia do trato digestivo de ruminantes / Development and physiology of the digestive tract of ruminants

Os animais ruminantes possuem algumas modificações em seu trato digestório decorrentes da evolução, tais modificações surgiram principalmente devido ao tipo de dieta desses animais, que é baseada em alimentos com alto teor de fibra. O estômago dos ruminantes é dividido em quatro compartimentos, sendo estes o rúmen, retículo, omaso e abomaso. Os três primeiros compartimentos (rúmen, retículo e omaso) abrigam os microrganismos e, portanto, possuem atividade fermentativa. O abomaso assemelha-se o estômago dos não ruminantes, possuindo epitélio revestido por mucosa com glândulas secretoras de ácido, muco e hormônios. A ingestão de forragem auxilia no desenvolvimento do tamanho e volume do rúmen, retículo e omaso, já a ingestão de alimento concentrado desenvolve as estruturas (papilas ruminais) do rúmen. Para que haja uma digestão dos alimentos de forma eficiente através dos microrganismos quês estão presentes no rúmen, as condições deste devem ser: pH ideal entre 5,5 e 6,8, substrato constante para fermentação, temperatura ideal entre 38 e 42 °C, anaerobiose, potencial redutor e taxa de passagem constante da digesta, além da remoção dos produtos da fermentação (AGCC, CH4, CO2, entre outros gases). Além dessas condições, existem funções motoras, de secreção e absorção do trato digestivo dos ruminantes que são reguladas pela interação dos mecanismos de controle do sistema nervoso central e pelo sistema endócrino, de maneira semelhante aos demais órgãos e sistemas do organismo. A complexa participação dos hormônios a garantir a degradação e absorção dos alimentos, dos quais são fundamentais para o desenvolvimento e produção dos animais ruminantes.(AU)

Ruminant animals have some modifications in their digestive tract, due to the evolution, such modifications arose mainly due to the type of diet of these animals, which is based on foods with high fiber content. The stomach of ruminants is divided into four compartments, being the rumen, reticulum, omasum and abomasum. The first three compartments (rumen, reticulum and omasum) harbor the microorganisms and, therefore, have fermentative activity. The abomasum resembles the stomach of non-ruminants, having mucosa-lined epithelium with acid-secreting glands, mucus, and hormones. The ingestion of forage aids in the development of the size and volume of the rumen, reticulum and omasum, while the ingestion of concentrated food develops the structures (ruminal papillae) of the rumen. In order to efficiently digest food through the microorganisms that are present in the rumen the conditions of this should be: ideal pH between 5.5 and 6.8, constant substrate for fermentation, ideal temperature between 38 and 42 °C, anaerobiosis , reducing potential and constant passage rate of the digesta, besides the removal of the products of the fermentation (AGCC, CH4, CO2, among other gases). In addition to these conditions, there are motor functions, secretion and absorption of the digestive tract of ruminants that are regulated by the interaction of central nervous system control mechanisms and the endocrine system, similar to other organs and systems of the body. The complex involvement of hormones will ensure the degradation and absorption of food, which are key to the development and production of ruminant animals. (AU)

Equações utilizadas para a predição de frequência cardíaca máxima na população pediátrica não atlética: uma revisão sistemática / Equations used to predict maximum heart rate in the non-athletic pediatric population: a systematic review

OBJETIVOS: Revisar a aplicabilidade das equações preditivas de frequência cardíaca máxima durante os testes de exercício em crianças e adolescentes não atletas. MÉTODOS: Trata-se de uma revisão sistemática, realizada no Pubmed, Lilacs, Scielo e PEDro. Foram incluídos estudos que compararam a frequência cardíaca máxima medida e a estimada por equações preditivas durante testes de esforço em crianças e adolescentes não atletas. Utilizou-se a seguinte estratégia de pesquisa: Exercise test OR Exercise testing OR Cardiopulmonary exercise test OR Cardiopulmonary exercise testing OR Peak oxygen uptake OR Maximal oxygen consumption OR Exercise tolerance OR Exercise capacity AND Heart rate OR Heart rates OR Pulse rate OR Pulse rates OR Heart rate control OR Cardiac chronotropic OR Predictive value test AND Predictive equations. A qualidade metodológica foi avaliada pela escala da Agency for Health Care Research and Quality. RESULTADOS: De um total de 858 artigos localizados, apenas quatro foram incluídos. Os artigos totalizaram 325 participantes (sete a 18 anos). Todos os estudos mensuraram a frequência cardíaca máxima por meio do teste de esforço cardiopulmonar. Enquanto nenhum estudo (04/04=100%; 01/01=100%) recomendou as fórmulas "220 - idade" e a "207 ­ 0,7 x idade", as equações "208 ­ (0,7 x idade)" e a "200 ­ 0,48 x idade" foram adequadas em 02/03 (66,6%) artigos e 01/01 (100%) documentos, respectivamente. A qualidade metodológica foi considerada alta em todos os artigos avaliados, oscilando entre 76 e 97 pontos. CONCLUSÕES: Os achados parecem sugerir que a fórmula "208 ­ (0,7 x idade)" foi a equação mais testada e adequada em grande parte para estimar os valores de frequência cardíaca máxima em crianças e adolescentes não atletas. No entanto, ainda são necessários mais estudos para confirmar esses resultados.

AIMS: To evaluate the applicability of the predictive equations of maximum heart rate during exercise tests in non-athlete children and adolescents. METHODS: It is a systematic review, carried out through Pubmed, Lilacs, Scielo and PEDro. We included studies comparing the maximum heart rate measured and estimated by predictive equations during stress tests in non-athlete children and adolescents. The following search strategy was used: Exercise test OR Exercise testing OR Cardiopulmonary exercise test OR Cardiopulmonary exercise testing OR Peak oxygen uptake OR Maximal oxygen consumption OR Exercise tolerance OR Exercise capacity AND Heart rate OR Heart rates OR Pulse rate OR Pulse rates OR Heart rate control OR Cardiac chronotropic OR Predictive value test AND Predictive equations. The methodological quality was assessed by the Agency for Health Care Research and Quality scale. RESULTS: Of a total of 858 articles located, only four were included. The articles totaled 325 participants (seven to 18 years). All studies measured the maximum heart rate by cardiopulmonary stress test. While no study recommended (04/04=100%; 01/01=100%) the formulas "220 - age" and "207 - 0.7 x age", the equations "208 - (0.7 x age)" and "200 - 0.48 x age" were adequate in 02/03 (66.6%) articles and 01/01 (100%) document, respectively. The methodological quality was considered high in all articles evaluated, ranging from 76 to 97 points. CONCLUSIONS: The findings seem to suggest that the formula "208 - (0.7 x age)" was the most tested and adequate equation to a large extent for estimating maximum heart rate in non-athlete children and adolescents. However, further studies are still needed to confirm these results.

Fatty acid, physicochemical composition and sensory attributes of meat from lambs fed diets containing licuri cake.

The aim of this study was to determine the effect of feeding licuri cake to lambs on the sensory characteristics, physicochemical characteristics and fatty acid (FA) profile of meat from lambs. Forty-four crossbred Santa Ines lambs (21.2 ± 2.70 kg body weight; 6 months old) were housed in individual pens and fed 4 experimental diets, containing 0, 8, 16 or 24% licuri cake (DM basis). The averages concentrations of ash (11.4), pH (5.82), lightness (38.1), cooking loss (26.8) or shear-force resistance (2.48) of lamb meat were not affected by the licuri cake diets. However, there was a linear decrease (P < 0.01) of redness and chroma indexes, lipid and protein contents, whereas the moisture content of the meat (P < 0.001) increased linearly due to the inclusion of licuri cake in lambs' diets. The licuri cake inclusion in the lambs feed linearly increased (P < 0.05) the fatty acids concentrations of C12:0, C17:0, C20:0, C20:1, C18:3, C20:3, C20:4 and ΣPUFA/ΣMUFA ratio, Σω-3 and atherogenicity index (AI). However, C18:1 cis, C20:2, C20:5, ΣMUFA, ΣMUFA/ΣSFA and Σω-6:Σω-3 ratios in the longissimus lumborum of lambs linearly decreased by licuri cake inclusion. There was a quadratic increase (P < 0.05) on C14:0 (maximum point 4.94 g/100 g FAME to 14.5% licuri inclusion), C16:1 (maximum point 8.59 g/100 g FAME to 10.7% licuri inclusion) and enzymatic activities of Δ9-desaturase C16 (maximum point 27.5 g/100 g FAME to 10.6% licuri inclusion) in the longissimus lumborum of lambs fed due to increased concentrations of licuri cake. However, there was a quadratic decrease (P = 0.04) in ΣPUFA/ΣSFA ratio with minimum concentration of 0.63 g/100 g FAME to 11.1% inclusion. The inclusion of licuri cake in the lambs diet did not change (P > 0.05) the concentrations of SFA C10:0, C15:0, C16:0, C18:0, C14:1, MUFA C18:1 trans, PUFA C18:2 cis, CLA, total sum of ΣSFA and ΣPUFA, desirable fatty acids (DFA), hypocholesterolemic:hypercholesterolemic index, and elongase and Δ9-desaturase C18 enzymes. Licuri cake in the lamb diet improved (P < 0.05) meat aroma, flavor and overall acceptance by consumers. Licuri cake inclusion in the diet of lambs improves sensory attributes of meat and the meat fatty acid profile becomes nutritionally healthier for the human diet because do not affect major FA of meat; however, the growth performance of finishing lambs is reduced.

Feeding sunflower cake from biodiesel production to Santa Ines lambs: Physicochemical composition, fatty acid profile and sensory attributes of meat.

The aim of this study was to determine the effect of the inclusion of sunflower cake in the diets of lambs on meat quality. Forty male, uncastrated Santa Ines lambs with an initial average body weight of 20.9 ± 0.41 kg were used in a completely randomized design with four treatments. The lambs were fed 500 g/kg hay and 500 g/kg concentrate (corn, soybean meal, urea, ammonium sulfate and sunflower cake) in their diet, and the experimental treatments were 0, 10, 20, and 30% sunflower cake inclusion (DM basis). The inclusion of sunflower cake in the diet did not affect (P > 0.05) the content of ash and protein, overall acceptance, or sensory aroma of the lamb meat. Total lipids and moisture content of the longissimus lumborum muscle increased linearly (P ≤ 0.05) with sunflower cake inclusion. The C16:0, ΣSFA, ΣMUFA:ΣSFA ratio, Δ-9 desaturase enzyme and atherogenicity index in the longissimus lumborum muscle decreased linearly (P ≤ 0.05) with sunflower cake inclusion in lamb diets, whereas a linear increase occurred (P ≤ 0.05) in C12:0, C18:0, ΣMUFA, ΣPUFA, ΣPUFA:ΣSFA and ΣPUFA:ΣMUFA ratios, Σn-6, Σn-3, desirable fatty acids, h:H index, elongase activity, and flavor, tenderness and juiciness sensory qualities in lamb meat. Among the panelists, the highest preference (35.9%) was for meat with 30% sunflower cake inclusion in the diet. Sunflower cake up to 30% of total DM can be included in the diet of Santa Ines lambs, because lipid nutritional quality and the sensory qualities of the lamb meat increase, in addition to improvement in nutraceutical compounds, such as the CLA content, and in the AI, PUFA:SFA and PUFA:MUFA ratios, desirable fatty acids content and h:H ratio, which are beneficial to the health of consumers.
