Introduction: Adolescence is characterized as a transition period between childhood and adult
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.
Intestinal mucositis is a frequent complication in the treatment of cancer with the chemotherapeutic agent 5‐fluorouracil (5‐FU). So far there is still no effective treatment of this condition. Cashew gum (CG) has been reported as a potent anti‐inflammatory. The present study aimed to evaluate the effect of Cashew gum (Anacardium occidentale L.) on 5‐fluorouracil‐induced intestinal mucositis in Swiss mice. The mice (25–30g) were secreted into 5 groups (n = 6): Saline group (NaCl 0.9%), 5‐FU group, CG group (90mg/kg CG, vo), CLX group (Celecoxib ip), CLX + CG group (Celecoxib ip, 90mg/kg GC). All animals except Saline group received 5‐FU at the concentration of 450mg/kg in the first experimental protocol. Duodenal portions were removed for evaluation of mucositis by histopathological and immunohistochemical analysis for cyclooxygenase‐2 (COX‐2). The results of the histopathological analysis demonstrated that 5‐FU promoted structural alterations of the intestinal mucosa, evidenced by the reduction of villi height, deepening of the crypts, and intense inflammatory infiltrate, in comparison to the Salina group, characterized by the integrity of the villi and crypts and absence of inflammatory infiltrate. CG animals showed a significant reversal of the effects promoted by antineoplastic in the villi, crypts and inflammatory cells infiltration in comparison to the 5‐FU group. CLX group, as well as CLX + GC, were able to significantly prevent (p <0.05) destruction of crypts, shortening of villi with cellular vacuolization, and inflammatory infiltrate. Regarding the immunoblotting for expression of COX‐2, it can be observed that the saline group showed subtle immunostaining when compared to the 5‐FU group (p <0.05), in which intense and generalized immunostaining was observed. In the CG, CLX and CLX + CG groups, there was a decrease in the immunostaining when compared to the 5‐FU lesion group. In addition, the amount of COX‐2‐immunolabelled cells in the CLX + CG group was lower than the CG treated group. It is concluded that CG prevented the intestinal mucosa promoted by the 5‐FU antineoplastic, in addition to decreasing the expression of the COX‐2 enzyme, an important element in the onset and exacerbation of inflammation.Support or Funding InformationThis study received funding of CNPQ and CAPESThis abstract is from the Experimental Biology 2019 Meeting.

Biochar is a product of the pyrolysis of organic waste with potential use in agriculture. Its use depends on its physico-chemical properties, which vary according to the biomass and the pyrolysis process. Agroindustry that processing oranges and bananas generate a large amount of residues. We produced biochars from banana peels and orange bagasse with pyrolysis at 400 and 600°C. The results showed a variation of properties as a function of the biomass and the pyrolysis temperature. All biochars showed alkaline pH. The banana peels biochars present high ash values and electrical conductivity. The carbon contents varies between 50-60%. The Cu contents limited the agricultural use, as well as the naphthalene content in the bagasse orange biochar at 600°C. Further studies on agronomic advantages and risks of the use of these biochars in tropical soils are needed. O biocarvão é um produto da pirólise de resíduos orgânicos com potencial uso na agricultura. A utilização depende de suas propriedades físico-químicas, que variam de acordo com a biomassa e o processo de pirólise utilizado. As agroindústrias de processamento de laranjas e bananas geram uma grande quantidade de resíduos. Foi produzido em reator biocarvão de cascas de banana e bagaços de laranja com nas temperaturas de 400°C e 600°C. Os resultados mostraram variação das características em função da biomassa e da temperatura de pirólise. Todos os biocarvões mostraram pH alcalino. Os biocarvões de casca de banana apresentam elevados valores de cinzas e condutividade elétrica. Os teores de carbono variaram 50-60%. Os teores de Cu limitam o uso agrícola, assim como o teor de naftaleno no biocarvão de bagaço de laranja carbonizado a 600°C. São necessários estudos complementares sobre vantagens agronômicas e riscos da utilização deste biocarvões nos solos tropicais.
