RESUMO Objetivos: Verificar se há concordância entre fonoaudiólogos e nutricionistas na classificação de consistências alimentares utilizadas em hospitais e as opiniões sobre as possíveis consequências das divergências nessa classificação. Métodos: Estudo descritivo transversal com 30 fonoaudiólogos e 30 nutricionistas que trabalhavam em 14 hospitais da rede pública e/ou privada de Belo Horizonte. Os profissionais responderam um questionário elaborado pelas pesquisadoras e classificaram cinco alimentos, com e sem direcionamento teórico. Empregaram-se os testes estatísticos Exato de Fisher e Z para comparação de proporções, com nível de significância de 5%. Resultados: Tanto fonoaudiólogos (100%) quanto nutricionistas (90%) percebem divergência nas classificações, sendo que, respectivamente, 86,2% e 100% acreditam que essa divergência pode prejudicar a recuperação dos pacientes. O risco de aspiração de alimento foi o prejuízo mais citado. Para a classificação geral das consistências alimentares, a maior parte dos profissionais (88,5%) sugeriu de quatro a seis termos. Quanto à terminologia utilizada na classificação dos alimentos apresentados sem direcionamento teórico, os profissionais citaram 49 termos e concordaram apenas na classificação do sólido e do líquido. Com o direcionamento teórico, os profissionais concordaram também na classificação do pastoso grosso e do pastoso fino. Conclusão: Tanto fonoaudiólogos quanto nutricionistas reconhecem divergências na classificação das consistências alimentares e o consequente risco de prejuízos à recuperação do paciente. A utilização do direcionamento teórico aumentou a concordância entre os profissionais.

ABSTRACT Purpose To verify if there is an agreement between speech-language pathologists and nutritionists about the classification of food textures used in hospitals and their opinions about the possible consequences of differences in this classification. Methods This is a descriptive, cross-sectional study with 30 speech-language pathologists and 30 nutritionists who worked in 14 hospitals of public and/or private network in Belo Horizonte, Brazil. The professionals answered a questionnaire, prepared by the researchers, and classified five different foods, with and without theoretical direction. The data were analyzed using Fisher's exact and Z -tests to compare ratios with a 5% significance level. Results Both speech-language therapists (100%) and nutritionists (90%) perceive divergence in the classification and, 86.2% and 100% of them, respectively, believe that this difference may affect the patients' recovery. Aspiration risk was the most mentioned problem. For the general classification of food textures, most of the professionals (88.5%) suggested four to six terms. As to the terminology used in the classification of food presented without theoretical direction, the professionals cited 49 terms and agreed only in the solid and liquid classifications. With theoretical direction, the professionals also agreed in the classification of thick and thin paste. Conclusion Both the professionals recognized divergences in the classification of food textures and the consequent risk of damage to patient's recovery. The use of theoretical direction increased the agreement between these professionals.

Simaba guianensis subesp. ecaudata (Simaroubaceae) is a tree found in the Brazilian Amazon. This work describes for the first time the fractionation of stems of this species that resulted in the isolation of the cytotoxic triterpene piscidinol A, the alkaloid 9-methoxycanthin-6-one, caryophyllene oxide, also isolated for the first time from this species and a new alkaloid (6-methoxy-(9H-β-carbolin-1-il)-(Z)-2-propenoic acid). Quantification of 9-methoxycanthin-6-one in different extracts and fractions of stems of S. guianensis by high performance liquid chromatography was also performed. The concentration of 9-methoxycanthin-6-one in methanolic and aqueous extracts were inferior to the known cytotoxic concentration of this compound.

The phytochemical investigation of the stem bark and leaves of G. elliptica provided a mixture of the norisoprenoids blumenol B and 6-epiblumenol B along with the triterpenes friedelin, as the major constituent, friedelanol, ursa-9(11),12-dien-3-ol, a-amyrin, β-amyrin, morentenol, epifriedelanol, as well as the sesquiterpenes trans-caryophyllene, α-humulene, ethyl hydnocarpate and other fatty acid esters. The identification of the compounds was performed on basis of spectrometric methods such as GC-MS, IR, MS and 1D and 2D NMR. Stem bark extracts showed significant leishmanicidal activity against promastigote forms of Leishmania braziliensis, with the best results for the chloroform extract.

bicyclogermacrene (35.12%), (E)-caryophyllene (14.19%) and α-copaene (8.19%). The antimicrobial and antileishmanial activities were investigated. The oil showed potent antimicrobial activity against Candida albicans and Rhodococcus equi. The oil also showed significant antileishmanial activity, giving the best results against Leishmania guyanensis. A preliminary cytotoxicity assay for this oil was carried out on hamster and mice (Balb/c) peritoneal macrophages. The results obtained were similar to pentamidine and considered not to be cytotoxic to macrophages.
