Ingestive behavior of calves fed diets based on corn grain and supplementary hay / Comportamento ingestivo de bezerros alimentados com dietas a base de milho grão inteiro e feno suplementar

In this work, the influence of the addition of Tifton-85 hay supplement to the corn grain mix and commercial pellet was assessed in terms of the digestive behavior exhibited by the dairy calves. The Latin square 4 x 4 duplicate and simultaneous design was adopted in this experiment, in which the treatments included four levels of the hay supplement Tifton-85 (0, 0.2, 0.4, and 0.8 %) with respect to body weight, in the corn grain mix and commercial pellet, over four experimental periods, with two repetitions (eight animals). The effect of the hay levels (P < 0.05) was evident in the time taken by the animals for feeding (TFE), rumination (TRU), and total chewing time (TCT), however, the time spent in leisure (TO) remained unaffected (P > 0.05). The variables, chew time per bolus (CT/bolus), and number of chews per bolus (NC/bolus) showed no differences among the treatments (P > 0.05), however, the number of chews per day (NC/day), and number of ruminal boluses (NRB) revealed significant variations (P < 0.05). Among the treatments, the effects on feed efficiency (EFDM) and rumination (ERUDM) of dry matter (P < 0.05) were evident, but the rumination efficiency of the neutral detergent fiber (ERUNDF), and rumination rate (RR) were not affected (P > 0.05). The supplementary levels of hay added to the diet increased the rumination and chewing times. 

Acompanhamento nutricional de adolescentes no Programa Saúde na Escola

Introduction: Overweight and obesity in childhood and adolescence are important public health problems. In this context, the school has been identified as a favorable environment for carrying out health education programs. The Health at School Program and its important performance stand out. Thus, considering these discussions, they ask: How are the actions developed by the Health at School Program, focused on nutrition, being implemented? Objective: Analyze the teenager monitoring in the School Health Program (PSE in Brazil) opposite actions to the nutritional aspects of adolescents. Methods: This is a descriptive, qualitative study in Juazeiro municipality North-Ce, with the subject 18 nurses of the Family Health Strategy (FHS) inserted in the PES that municipality. Results: Nurses have limited assistance in the face of food practices, which implies in its operations; report having difficulty performing their actions outside the conventional health units and focus on strategies for a food menu. Conclusion: The monitoring of adolescents in the School Health Program ahead nutritional value is still limited to preventive practices involving specific actions, limited to a Sfood education focused on the health problem and not the needs of adolescents.Introdução: O sobrepeso e a obesidade na infância e na adolescência constituem importantes problemas de saúde pública. Nesse contexto, a escola vem sendo apontada como um ambiente favorável para realização de programas de educação em saúde. Destaca-se o Programa Saúde na Escola e sua importante atuação. Assim, considerando essas discussões, questionam-se: Como estão sendo implementadas as ações desenvolvidas pelo Programa Saúde na Escola, voltadas para nutrição? Objetivo: Analisar o acompanhamento do adolescente no Programa Saúde na Escola (PSE) frente a ações voltadas para os aspectos nutricionais dos adolescentes.   Método: Trata-se de um estudo descritivo, qualitativo, realizado no município de Juazeiro do Norte-Ce, tendo como sujeitos 18 enfermeiros da Estratégia Saúde da Família (ESF) inseridos no PSE do referido município. Utilizou-se como técnica para coleta do material a entrevista semiestruturada e organizados seguindo a proposta da análise de conteúdo. Resultados: Evidenciou-se que os enfermeiros tem uma assistência limitada frente às praticas alimentares, o que implica na sua atuação; compreendem a educação em saúde na escola como intervenções pontuais e preventivista, assim como, relatam ter dificuldades em executar suas ações fora das unidades convencionais de saúde e focam em estratégias voltadas para um cardápio alimentar não na perspectiva de promover a saúde, atuando quando o problema é detectado. Conclusão: O acompanhamento dos adolescentes no Programa Saúde na Escola frente aos aspectos nutricionais ainda está limitada a práticas preventivistas, envolvendo ações pontuais, limitadas a uma educação alimentar focada no problema de saúde e não nas necessidades dos adolescentes

Can Resveratrol Treatment Control the Progression of Induced Periodontal Disease? A Systematic Review and Meta-Analysis of Preclinical Studies

Resveratrol is an anti-inflammatory compound found in several foods. Periodontal disease (PD) is associated to other systemic diseases, and inflammation may be responsible for the association. Consequently, controlling inflammation not only may benefit oral health but also may assist with the management of other chronic inflammatory conditions. We aimed to investigate the effects of resveratrol administration on PD control in preclinical studies. A systematic search was performed for scientific articles using both electronic databases and a manual search using combinations of the following keywords: “resveratrol” OR “3,5,4′-trihydroxystilbene” AND “periodontal disease” OR “periodontitis” OR “gingivitis”. Only in vivo original studies investigating resveratrol treatment on experimental animal models of PD were selected. A quality assessment of the studies was performed using the Animal Research Reporting In Vivo Experiment (ARRIVE) guidelines, and the risk of bias was assessed using the Syrcle tool. The search returned 570 articles, and 11 matched the inclusion criteria. A meta-analysis showed that resveratrol treatment attenuated alveolar bone loss (τ2 = 0.0041; 95% CI: −0.14; −0.04). The ARRIVE criteria reported a good quality of studies in general (mean score 28.5 ± 2.5). However, five Syrcle domains indicated a high risk of bias or did not present information clearly. We concluded that, in preclinical studies, resveratrol treatment prevented PD progression
