Uma reflexão sobre as conexões entrea fonoaudiologia e Saúde Única / A reflection on the connections betweenspeech therapy and One Health

A Saúde Única é uma crescente abordagem sistêmica para aumentar indissociavelmente os níveis de saúde das pessoas, dos animais e do ambiente no planeta. Por sua característica interdisciplinar e multidisciplinar, a Saúde Única tem arregimentado cada vez mais novos agentes na área de saúde, ampliando novas fronteiras de prática profissional. Objetivo: tendo em vista de que a abordagem sistêmica da Saúde Única (One Health) é holística, objetivou-se descrever e refletir sobre o papel da fonoaudiologia nesse contexto. Métodos: fez-se uma revisão de escopo sobre as ligações da fonoaudiologia com as desordens de saúde que são o foco em Saúde Única. Realizou-se uma procura de artigos nas plataformas PubMed e SciELO, com a combinação booleana dos indexadores "fonoaudiologia" e "Saúde Única", em idioma português; e as palavras "speech-language therapy" e "One Health" em idioma inglês. O operador booleano foi "E" e "AND". Adicionalmente, procurou-se teses e dissertações com esses mesmos operadores e combinações no Catálogo de Teses e Dissertações da CAPES. Analisou-se os dados por uma abordagem qualitativa, por isso os métodos estatísticos não foram aplicados. A partir dessa abordagem, complementou-se a argumentação com uma reflexão crítica sobre a inclusão da fonoaudiologia na estratégia de Saúde Única. Resultados: apenas na plataforma SciELO encontrou-se cinco obras com os descritores e a combinação "Saúde Única AND fonoaudiologia"; esse resultado é fortemente sugestivo de que o profissional em fonoaudiologia não tem sido incluído como um agente na abordagem Saúde Única. Contrariando esse cenário, argumenta--se que a fonoaudiologia pode preencher um nicho de trabalho e atuação acadêmica na abordagem de Saúde Única, cujo foco são desordens de saúde que podem resultar em distúrbios da comunicação nas pessoas. Considerações finais: há um nicho para a fonoaudiologia na abordagem da Saúde Única para a prevenção, o tratamento e a investigação científica das desordens da comunicação humana.

One Health is a growing systemic approach aimed at increasing the health levels of people, animals and the environment on the planet. Due to its inter- and multidisciplinary characteristics, One Health has been recruiting an increasing number of new agents in the health area, expanding new frontiers of professional practice. Objective: considering that the systemic approach of One Health is holistic, the objective is to describe and reflect on the role of speech therapy in this context. Methods: a scoping review was conducted to explore the connections between speech therapy and the health disorders that are the focus of One Health. A search for articles was carried out on the PubMed and SciELO platforms, using the Boolean combination of the terms "fonoaudiologia" (speech therapy) and "Saúde Única" (One Health), in Portuguese; and the words "speech-language therapy" and "One Health" in English using the Boolean operator "E" and "AND". Additionally, we searched for theses and dissertations with these same operators and combinations, in the CAPES Catalog of Theses and Dissertations. The data was analyzed using a qualitative approach, therefore statistical methods were not applied. Based on this approach, the argument was complemented with a critical reflection on the inclusion of speech therapy in the One Health strategy. Results: five works were found on the SciELO platform using the descriptors and combination "Saúde Única AND fonoaudiologia". This result suggests that the speech therapy professional has not been included as an agent in the One Health approach. Contrary to this scenario, it is argued that speech therapy can play a significant professional and academic role in One Health, which focuses on health disorders that may result in communication disorders. Final considerations: there is a niche for speech therapy in the One Health approach to the prevention, treatment and scientific investigation of human communication disorders.

Pelage variation and morphometrics of closely related Callithrix marmoset species and their hybrids.

BACKGROUND: Hybrids are expected to show greater phenotypic variation than their parental species, yet how hybrid phenotype expression varies with genetic distances in closely-related parental species remains surprisingly understudied. Here, we investigate pelage and morphometric trait variation in anthropogenic hybrids between four species of Brazilian Callithrix marmosets, a relatively recent primate radiation. Marmoset species are distinguishable by pelage phenotype and morphological specializations for eating tree exudates. In this work, we (1) describe qualitative phenotypic pelage differences between parental species and hybrids; (2) test whether significant quantitative differences exist between parental and hybrid morphometric phenotypes; and (3) determine which hybrid morphometic traits show heterosis, dysgenesis, trangression, or intermediacy relative to the parental trait. We investigated cranial and post-cranial morphometric traits, as most hybrid morphological studies focus on the former instead of the latter. Finally, we estimate mitogenomic distances between marmoset species from previously published data. RESULTS: Marmoset hybrid facial and overall body pelage variation reflected novel combinations of coloration and patterns present in parental species. In morphometric traits, C. jacchus and C. penicillata were the most similar, while C. aurita was the most distinct, and C. geoffroyi trait measures fell between these species. Only three traits in C. jacchus x C. penicillata hybrids showed heterosis. We observed heterosis and dysgenesis in several traits of C. penicillata x C. geoffroyi hybrids. Transgressive segregation was observed in hybrids of C. aurita and the other species. These hybrids were also C. aurita-like for a number of traits, including body length. Genetic distance was closest between C. jacchus and C. penicillata and farthest between C. aurita and the other species. CONCLUSION: We attributed significant morphometric differences between marmoset species to variable levels of morphological specialization for exudivory in these species. Our results suggest that intermediate or parental species-like hybrid traits relative to the parental trait values are more likely in crosses between species with relatively lesser genetic distance. More extreme phenotypic variation is more likely in parental species with greater genetic distance, with transgressive traits appearing in hybrids of the most genetically distant parental species. We further suggest that fewer developmental disturbances can be expected in hybrids of more recently diverged parental species, and that future studies of hybrid phenotypic variation should investigate selective pressures on Callithrix cranial and post-cranial morphological traits.

Olfactory Enrichment in Hoary Foxes (Lycalopex vetulus LUND 1842): A Case Study.

We have tested a method of olfactory environmental enrichment in hoary foxes used in other wild canids in captivity. The individuals were exposed to four olfactory stimuli (meat, mouse urine, cheese, and egg) that were wrapped in cotton bags outside the enclosures at the zoo for five minutes. Behavioral observations were performed using the focal animal method, and all occurrences were recorded. The pre-exposure phase (Basal), exposure phase (Exp), and post-exposure phase and Basal phase (Pos) were analyzed for a period of five minutes. Behavioral responses were categorized as positive, negative, or other. Positive behavior tended to increase (p = 0.07) from the Basal phase to the Exp phase, but there was no statistical difference (p = 0.31) between the phases. Negative and other behavior did not differ statistically from the Basal phase to the Exp phase (N-, p = 0.32; Ot, p = 0.35) or Basal to the Pos phase (N-, p = 0.18; Ot, p = 0.92). The odors used seemed to elicit positive behavior weakly. Negative behavior was stable for the hoary foxes. The method failed to improve the hoary foxes' welfare. Because their natural diet is based on insects and fruits, it is suggested that the stimuli used in this study have no appetitive value for hoary foxes. The method used with the same olfactory stimuli that were successful in other canid species is unsuitable for hoary foxes.

Olfactory stimulus as environmental enrichment for shelter dogs: a pilot study / Estímulo olfativo como enriquecimento ambiental para cães de abrigo: um estudo piloto

Environmental enrichment techniques include olfactory stimuli for improving animal welfare. This study aimed to analyze the reactions of 41 shelter dogs exposed to odorous stimuli, such as the method used in another study on wild canids. The focal animal method analyzed the dogs' reactions, with all behaviors recorded. Behavioral responses were classified as positive (P+), negative (N-), or other (Ot). Independent variables were all dogs and the size of the packs. The behavior between the basal (without stimulus), exposure, and after-stimulus withdrawal was analyzed. For all dogs, olfactory stimuli significantly increased P+ (P=0.001) and N- (P=0.004), contrasting with the decrement of Ot behaviors (P=0.001) from the basal to the exposure phase. After the withdrawal of the stimuli, P+, N-, and Ot behaviors returned to basal levels (P>0.05). There were no significant differences (P>0.05) in the conduct of small or large packs exposed to stimuli. Dogs are sensitive to olfactory stimuli, but arousal is generalized to P+ and N-. It is undesirable to an N- increase for improvement of animal welfare. Contrary to what was observed in a study with wild canids, the method failed in shelter dogs because N- was increased. The introduction of sudden novelty (olfactory stimulus) in an impoverished shelter environment may have caused excitement in the dogs. It is suggested that changes in the method, such as stimuli exposition to each dog in an isolated room, are necessary to increase sheltered dog well-being.(AU)

As técnicas de enriquecimento ambiental incluem estímulos olfativos para aumentar o bem-estar animal. O objetivo deste estudo foi analisar as reações de 41 cães de abrigo expostos a estímulos odoríferos, como o método utilizado em outro estudo com canídeos selvagens. As reações dos cães foram analisadas pelo método animal focal, com todos os comportamentos registrados. As respostas comportamentais foram classificadas como positivas (P+), negativas (N-) ou outras (Ot). As variáveis independentes foram todos os cães e o tamanho das matilhas. Foi analisado o comportamento entre o basal (sem estímulo), exposição e após a retirada do estímulo. Para todos os cães, os estímulos olfativos aumentaram significativamente P+ (P=0,001) e N- (P=0,004), contrastando com a diminuição dos comportamentos Ot (P=0,001) da fase basal para a de exposição. Após a retirada dos estímulos, os comportamentos P+, N- e Ot retornaram aos níveis basais (P>0,05). Não houve diferenças significativas (P>0,05) no comportamento de matilhas pequenas ou grandes expostas a estímulos. Os cães são sensíveis a estímulos olfativos, mas a excitação parece ser generalizada para ambos, P+ e N-. É indesejável um aumento de N- para melhoria do bem-estar animal. Ao contrário do que foi observado em um estudo com canídeos selvagens, o método falhou em abrigar cães porque o N- foi aumentado. A introdução de uma novidade repentina (estímulo olfativo) em um ambiente de abrigo empobrecido, pode ter causado excitação exagerada nos cães. Sugere-se alterações no método, como a exposição de estímulos a cada cão em uma sala isolada necessária para aumentar o bem-estar do cão abrigado.(AU)

No Evidence of Rabies Exposure in Wild Marmosets (Callithrix jacchus) of Northeast Brazil.

Rabies transmitted by wildlife is the main source of human rabies mortality in Latin America and considered an emerging disease. The common marmoset Callithrix jacchus of Brazil is the only known primate reservoir of rabies worldwide. We tested whether alive free-ranging C. jacchus were exposed to rabies in four northeast states that have previously reported rabies-positive dead C. jacchus (Pernambuco and Bahia) or not (Paraíba and Rio Grande do Norte). Our results show no evidence of rabies antibodies or infection in the sampled C. jacchus, suggesting that apparently healthy marmosets are not widely exposed to rabies over their natural range.

Tree Species and Morphology of Holes Caused by Black-Tufted Marmosets to Obtain Exudates: Some Implications for the Exudativory.

Knowledge of the pattern of exploitation of trees can help us understand the relationship between marmosets and plants, especially in declining forests, such as those in the Brazilian Cerrado. Black-tufted marmosets (Callithrix penicillata) regularly exploit exudates by gouging the bark of trees with their specialized teeth. Determining preferred tree species to exploit exudates is important for forest management aimed at maintaining an essential food source for urban marmosets. We characterized the tree species, dendrometry, and the characteristics of the holes made by marmosets to obtain exudates. Based on these data, we proposed a gouging effort index (Chiseling Suitability Index for Marmosets, ChiSI). We identified 16 species belonging to 10 families of trees with gouging marks made by marmosets. Eleven new tree species used by black-tufted marmosets for exudates were identified in urban forests in the Cerrado. Exudate exploration was predominantly of medium intensity, with round holes concentrated in the canopy. The species Tapirira guianensis and Croton urucarana were preferred. The ChiSI was characterized by a narrow range for both T. guianensis and C. urucarana. Despite the flexibility of obtaining exudates, the black-tufted marmosets concentrate their exploitation to only a few tree species. The T. guianensis and C. urucarana tree species should be considered the most important species for management plans and the preservation of black-tufted marmosets that live in urban forests in the Cerrado.

Spatio-temporal dynamics of rabies and habitat suitability of the common marmoset Callithrix jacchus in Brazil.

Rabies transmitted by wildlife is now the main source of human rabies in the Americas. The common marmoset, Callithrix jacchus, is considered a reservoir of rabies causing sporadic and unpredictable human deaths in Brazil, but the extent of the spillover risk to humans remains unknown. In this study, we described the spatiotemporal dynamics of rabies affecting C. jacchus reported to Brazil's Ministry of Health passive surveillance system between 2008 and 2020, and combined ecological niche modelling with C. jacchus occurrence data to predict its suitable habitat. Our results show that 67 outbreaks (91 cases) of rabies affecting C. jacchus were reported by 41 municipalities between January 2008 and October 2020, with a mean of 5 outbreaks/year [range: 1-14]. The maximum number of outbreaks and municipalities reporting cases occurred in 2018, coinciding with higher surveillance of primate deaths due to Yellow Fever. A mean of 3 [1-9] new municipalities reported outbreaks yearly, suggesting potential spatial expansions of the C. jacchus variant in northeastern Brazil and emerging rabies spillover from vampire bat Desmodus rotundus to C. jacchus in the north and south. Outbreaks were concentrated in the states of Ceará (72%) and Pernambuco (16%) up to 2012, but are now reported in Piauí since 2013, in Bahia since 2017 (D. rotundus' antigenic variant, AgV3) and in Rio de Janeiro since 2019 (AgV3). Besides confirming suitable habitat for this primate in the northeast and the east coast of Brazil, our Maximum Entropy model also predicted suitable habitat on the north and the west states of the country but predicted low habitat suitability among inland municipalities of the Caatinga biome reporting rabies. Our findings revealed new areas reporting rabies infecting C. jacchus, highlighting the need to implement strategies limiting spillover to humans and to better understand the drivers of C. jacchus rabies dynamics.

Potentially harmful materials in the feces of wild ring-tailed coatis (Nasua nasua) and health implications / Materiais potencialmente nocivos encontrados nas fezes de quatis (Nasua nasua) selvagens e implicações para a saúde

In ecological parks, the proximity to tourist activities facilitates the exploration of garbage by coatis, with possible serious consequences for the animals health . We described the contents of wild coatis feces from three ecological parks. After analyzing 62 samples, fragments of plants and animals were identified in all feces. In the feces of two parks, seeds were present between 36.4% and 48.6% of the samples. Arthropod fragments were identified in 100% of the samples from two parks, but only 87.3% in a third park. Scales, bones or bird feathers were present in some samples. Undigested material of industrial origin was detected in 34.3% to 54.5% of the samples, such as fragments of paper, string, plastic, aluminum, latex and glass. Results are in line with other studies on the diet of wild coatis, but the intake of foreign bodies, potentially harmful to health, is described for the first time. Clinical problems resulting from ingesting waste can be dental fractures, mucosal erosions, intestinal perforation, peritonitis, impaction, diarrhea, weight loss, intoxication and infections. Coatis in the three parks are at risk of health, and actions are needed to avoid clinical and potentially fatal problems. Four actions are recommended to avoid ingesting foreign bodies: increasing the environmental education of visitors; improving the storage of waste generated in parks; periodically monitor the health of coatis, in order to make interventions when possible; make a permanent program to study the ecology of species in the three parks.

Em parques ecológicos, a proximidade com atividades turísticas facilita a exploração do lixo por quatis (Nasua nasua), com possíveis consequências graves para saúde dos animais. Descrevemos o conteúdo de fezes de quatis selvagens de três parques ecológicos. Após análise de 62 amostras, fragmentos de plantas e animais foram identificados em todas as fezes. Nas fezes de dois parques, as sementes estiveram presentes entre 36,4% e 48,6% das amostras. Foram identificados fragmentos de artrópodes em 100% das amostras de dois parques, mas apenas 87,3% em um terceiro parque. Escamas, ossos ou penas de pássaros estavam presentes em algumas amostras. Detectou-se material não digerido de origem industrial em 34,3% a 54,5% das amostras, como fragmentos de papel, barbante, plástico, alumínio, látex e vidro. Os resultados estão de acordo com outros estudos sobre a dieta de quatis selvagens, mas a ingestão de corpos estranhos, potencialmente prejudicial à saúde, é descrito pela primeira vez. Os problemas clínicos decorrentes da ingestão de lixo podem ser fraturas dentais, erosões de mucosas, perfuração intestinal, peritonite, impactação, diarreia, emagrecimento, intoxicação e infecções. Os quatis nos três parques estão com a saúde em risco, sendo necessárias ações para evitar problemas clínicos e potencialmente fatais. Quatro ações são recomendadas para evitar a ingestão de corpos estranhos: aumentar a educação ambiental dos visitantes; melhorar o armazenamento dos resíduos gerados nos parques; monitorar periodicamente a saúde dos quatis, de forma a fazer intervenções quando possível; fazer um programa permanente de estudo da ecologia das espécies nos três parques.

Feeding Ecology of Wild Brown-Nosed Coatis and Garbage Exploration: A Study in Two Ecological Parks.

Wild animals that feed on garbage waste are a problem in ecological parks as it can substantially alter their food ecology. Wild coatis that occupy human recreation areas in parks are often observed feeding on garbage, but the ecological consequences are scarcely known. Forty-four fecal samples from females and 12 from males of wild coatis living in two ecological parks (Parque Municipal das Mangabeiras (PMM) and Parque Nacional do Caparaó (PNC)) were analyzed. Multivariate statistics were applied to evaluate the interaction between four variables (fecal volume, composition, place and sex of coatis). A significant interaction between the parks and sexes with regard to volume and food category was not found. Ungrouped analysis allowed for the identification of a decreasing gradient in volume from PNC males, followed by PNC females, PMM males, and PMM females. We did not find differences between categories of food between males and females from PNC and PMM, except for invertebrates. Females from PNC consumed more invertebrates than males and females of PMM, but we did not find differences from PNC males. The coatis of both parks primarily consume invertebrates and vegetables, but garbage residues were found in their feces. Garbage fragments, such as paper, glass, metal, plastic and rope, cause a risk to the health, compromising the conservation efforts of wild coatis. Actions are needed to prevent the access of coatis to dumps in both parks.
