The nutritional composition of bovine liver, particularly in terms of vitamins E, ß-carotene, and cholesterol concentration, is significantly influenced by the cattle-rearing system and diet. This study aimed to elucidate the impact of four predominant cattle-rearing systems in the Eastern Amazon region on the vitamin E, ß-carotene content, and cholesterol levels in bovine liver during the rainy season. Liver-tissue samples were collected from 48 cattle, with twelve specimens representing each rearing system. The systems encompassed two native pastures located in flood-prone areas, cultivated pastures on upland terrain and a confinement-rearing system. Our findings indicate that, when considering all rearing systems collectively, there were no significant differences in the levels of vitamins and cholesterol in the liver tissues (p > 0.05). However, a marked disparity in cholesterol levels emerged when comparing intensive rearing systems to extensive ones, with the former demonstrating notably higher concentrations (p = 0.01). Additionally, the intensive rearing system was associated with elevated levels of ß-carotene (p < 0.01), α-tocopherol (p = 0.01), and ß-tocopherol (p = 0.01) relative to the extensive systems. No significant variations were observed amongst the different extensive systems (p > 0.05). These results suggest that, while all rearing systems yielded liver tissues with typical concentrations of vitamins and cholesterol, the intensive rearing system led to a higher accumulation of certain vitamin compounds. This study highlights the substantial nutritional implications of different cattle-rearing systems in the Eastern Amazon and provides valuable insights for developing dietary strategies to optimize the nutritional quality of bovine liver. Therefore, the generated results are groundbreaking in the Eastern Amazon, Brazil, and inspire the development of new research projects to address other demands in this field and achieve additional outcomes.
Introduction: The quality of meat, with a focus on compounds important for human health, is directly related to the rearing systems in which the animals are produced. The search for a balanced diet, with an emphasis on low cholesterol and adequate levels of vitamins, aligns with society's emphasis on healthy eating, directly correlated with the importance of the offer made by producers for the cattle's diet. Objective and methodology: The objective was to verify the impact of different rearing systems, in the Eastern Amazon, during the rainy season, on the concentrations of vitamins (A, E) and cholesterol in the muscle (Longissimus lumborum) of crossbred Nelore cattle, castrated, aged between 24 and 36 months, and weighing between 410 and 628 kg. Twelve animals, from each of the three pasture rearing systems: native pasture in flooded areas of Monte Alegre; native pasture in a flooded area of Santa Cruz do Arari; and pasture cultivated on dry land in São Miguel do Guamá, all located in Pará, Brazil-were sampled in commercial slaughterhouses. Results: A notable influence was observed in the concentrations of ß-carotene (p < 0.01), α-Tocopherol (p = 0.02), ß-Tocopherol (p < 0.01) and the combined sum of ß-Tocotrienol and γ-Tocopherol (p < 0.01), as well as δ-Tocopherol (p < 0.01) when contrasting extensive with intensive systems (confinement). However, there was a difference in the content of vitamins and cholesterol between the isolated extensive systems, or between the four rearing systems (p > 0.05). Extensive systems, mainly in Monte Alegre, demonstrated greater amounts of α-Tocopherol and δ-Tocopherol. Conclusion: On the other hand, the intensive system exhibited higher levels of other investigated compounds, clarifying the nutritional variations generated by different livestock rearing practices in the region. Therefore, the results obtained are innovative in the Eastern Amazon, Brazil, in addition to inspiring the development of new research to meet other demands in this field, and achieve additional results, such as determining which meat, coming from cattle in production systems in the country, presents the better compositional quality of vitamins and lipids.
Objetivo descrever o perfil clínico epidemiológico de crianças submetidas à cirurgia de gastrostomia. Métodos estudo transversal, documental, retrospectivo desenvolvido em um hospital de referência em saúde da criança. Os dados foram coletados em prontuários e no livro de cirurgias. Resultados entre 39 prontuários analisados a maioria é do sexo feminino, nascidos de parto vaginal, idade gestacional a termo, sem informação sobre o índice de APGAR, com alguma comorbidade, idade entre 0-3 anos. A principal indicação para gastrostomia foi o distúrbio de deglutição de origem muscular ou neurológica com predomínio da técnica cirúrgica, uso de cateter de foley em látex como dispositivo para nutrição enteral, a primeira troca do dispositivo ocorreu entre 21 a 30 dias realizada pelo enfermeiro. Conclusão constatou-se a prevalência de meninas, com idade entre zero a três anos com alguma comorbidade. Os distúrbios de deglutição constituíram a indicação de gastrostomia confeccionada por meio de técnica cirúrgica.
Objective to describe the epidemiological clinical profile of children undergoing gastrostomy surgery. Methods cross-sectional, documentary, retrospective study developed at a referral hospital for child health. Data were collected from records and in the surgery book. Results among 39 medical records analyzed, most were female, born vaginally, gestational age at term, with no information on the Apgar index, with some comorbidity, aged 0-3 years. The main indication for gastrostomy was the swallowing disorder of muscular or neurological origin with predominance of the surgical technique, use of latex Foley catheter as a device for enteral nutrition, the first exchange of the device occurred between 21 to 30 days performed by the nurse. Conclusion the prevalence of girls aged zero to three years with some comorbidity was found. Swallowing disorders were the indication of gastrostomy made by surgical technique.
