Estudo etnobotânico na comunidade de Taquara : a luta pelo uso de plantas nativas pelo povo Kaiowá, MS, Brasil
Dissertação (mestrado)—Universidade de Brasília, Instituto de Ciências Biológicas, Departamento de Botânica, 2017.Este estudo foi desenvolvido com indígenas do tronco Guarani, etnia Kaiowá, do Tekoha Taquara, em Juti, Mato Grosso do Sul (MS). Este grupo foi expulso de sua terra ancestral, estando acampados na área que hoje, é uma propriedade particular, denominada Fazenda Brasília do Sul. Embora haja uma Portaria Declaratória que reconhece a terra indígena Taquara, seus efeitos foram suspensos por liminar. Os Kaiowá do Taquara estão sendo massacrados por esta briga de posse. O presente estudo é uma demanda desta comunidade e tem a pretensão de legitimar, mais uma vez, que aquela área é a terra ancestral deste povo. Para tanto, foi feito o levantamento das espécies de uso medicinal e a comparação com dados de literatura e de herbários. Os dados foram coletados através de turnês guiadas. Dois indígenas biólogos auxiliaram como interlocutores, facilitando a interação com sete informantes. As informações coletadas incluem o nome em Guarani, a tradução, o nome popular em português, os usos e partes das plantas usadas. Os informantes do Taquara apontaram 106 espécies de uso medicinal das quais, 90 foram identificadas até espécie. Esta lista apresentada é a maior em número de espécies entre os artigos que envolveram comunidades indígenas e a terceira maior lista para o MS. As famílias mais ricas foram Asteraceae (9 espécies) e Fabaceae (8 espécies). Os usos foram padronizados pela Classificação Internacional de Doenças (ICD) da Organização Mundial de Saúde (OMS). Os usos das plantas de Taquara abrangeram o maior número de categorias, tendo o sistema genito-urinário como a categoria com a maior citação. Há espécies na área do Tekoha Taquara que estão na lista de ameaçadas e outras, que não ocorrem mais na área. Plantas que aparecem na cosmologia deste grupo, foram coletadas, revelando conhecimento antigo da vegetação. Essa informação foi comparado com a de sete estudos e com a de dados armazenados em herbário. Foi gerada uma matriz de similaridade com base no índice de Sorensen. A compilação dos dados de literatura com herbário traz uma lista inédita de 628 espécies de plantas medicinais para o MS. Taquara se destaca com 61,1% de espécies exclusivas. A comparação da homogeneidade dos usos foi feita pelo Fator de Consenso dos Informantes (FIC), tratando-se como informante cada artigo, que ilustrou pouca consistência de usos entre os grupo no estado. Este estudo é o primeiro a relatar a mistura de espécies para o tratamento de doenças. A aglomeração dos resultados demonstra a singularidade, especifidade e antiguidade do conhecimento associado às plantas dos Kaiowá de Taquara. Isso sugere que seu conhecimento é o resultado de anos de co-evolução com a flora local deste território, afirmando que de fato, Taquara é a terra ancestral dos Kaiowá.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES).This study took place with indigenous people of Kaiowá ethnicity of the Guarani linguistic trunk from the Tekoha Taquara, in the municipal Juti, in the state of Mato Grosso do Sul (MS). This group has been expulsed from their ancestral territory. Wishing to remain on their land, the Kaiowá of Taquara camp on what is today considered the private property of Fazenda Brasília do Sul. Though the declaratory decree that recognizes Taquara as an indigenous territory was released in 2010, its effects have been suspended since its release. The Kaiowá of Taquara are being massacred by the omission of land demarcation. This study will demonstrate that this area is the ancestral land of this people, through the lens of traditional knowledge associated with local flora. To this end, species with medicinal uses were surveyed. The data was collected via guided tours. Two indigenous biologists assisted as interlocutors who facilitated interaction with seven indigenous informants. The information collected includes Guarani name of plants, the formal 7 translation, the popular name in Portuguese, and the related use and parts used of each plant. The Taquara informants revealed 106 medicinal species, of which 90 were identified to the specific level. In terms of number of species, this is the largest list of any known study realized with indigenous communities in the state, and the third largest list for the state of MS. The families with most commonly represented species were Asteraceae (9 species) and Fabaceae (8 species). The related uses were standardized according to the International Classification of Disease (ICD) of the World Health Organization (WHO). The uses of Taquara’s plants reached the largest number of categories, with the genito-urinary system having the most citations. Endangered species were found in Taquara, and information about others that no longer occur in the area was communicated by the informants and tracked in the study. Plants that appear in the cosmology of this indigenous group were cited, revealing ancient knowledge of the vegetation. Data collected was compared with seven ethnobotanical articles registered in MS and with other herbarium data within the state, from which a similarity matrix was generated. Compiling literature and herbarium data produced a list of 628 medicinal plants for the state of MS. Taquara stands out, with 61,1% of the species cited in no other study. Informant Consensus Factor (FIC) was used to compare the homogeneity of the plant uses across the state, treating each article as a citation an informant, which illustrated little consistency of plant uses throughout groups. The present study is the first to report the combination of different species in the treatment of illnesses. The amalgamation of results demonstrates the uniqueness, specificity and antiquity of the plant knowledge of the Kaiowá of Taquara. This suggests that their knowledge is the result of years of co-evolution of the local flora of this territory, indeed affirming Taquara as the ancestral land of the Kaiowá
A pilot study of the breath stacking technique associated with respiratory muscle endurance training in patients with amyotrophic lateral sclerosis: videofluoroscopic findings in the upper airway
Introduction: Bulbar impairment represents a hallmark feature of amyotrophic lateral sclerosis (ALS) that significantly impacts survival and quality of life. Respiratory complications arise because of the weakness of the upper airway and respiratory muscles leading to respiratory failure, impaired swallowing, and reduced airway safety. Breath stacking and respiratory muscle endurance training are techniques that have been described to improve respiratory and bulbar function in patients with ALS. Considering the above, a respiratory technique named TR3 was developed. This study aimed to measure the acute effects of this technique on the upper airway through videofluoroscopy and to assess its clinical trial feasibility in patients with ALS.Material and methods: In this cross-sectional study, we enrolled participants diagnosed with ALS to perform a single session of TR3. Epidemiological data and baseline assessments were collected. The assessments included kinematics from videofluoroscopy measuring the retropalatal airspace size, the size of the narrowest airway, and the pharyngeal area during rest and TR3.Results: Eight participants were included. During TR3, an acute increase of 15% was observed in the retropalatal airspace size (t = 5.14, p < 0.01), a 123% increase was observed in the size of the narrowest airway (t = –4.18, p < 0.001), and a 277% increase was observed in the pharyngeal area (t = –5.34, p < 0.001).Conclusions: During the intervention, TR3 showed acute effects in increasing pharyngeal constriction, pharyngeal expansion, retropalatal airspace size, and post-lingual narrowest airway size and is feasible for a larger research program. A clinical trial (NCT04226144) is already being conducted to assess the chronic therapeutic effects of this technique and its impact on the clinical evolution of ALS
