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.

Mutations in glioblastoma proteins do not disrupt epitope presentation and recognition, maintaining a specific CD8 T cell immune response potential.

Antigen-specific cytotoxic CD8 T cells are extremely effective in controlling tumor growth and have been the focus of immunotherapy approaches. We leverage in silico tools to investigate whether the occurrence of mutations in proteins previously described as immunogenic and highly expressed by glioblastoma multiforme (GBM), such as Epidermal Growth Factor Receptor (EGFR), Isocitrate Dehydrogenase 1 (IDH1), Phosphatase and Tensin homolog (PTEN) and Tumor Protein 53 (TP53), may be contributing to the differential presentation of immunogenic epitopes. We recovered Class I MHC binding information from wild-type and mutated proteins using the Immune Epitope Database (IEDB). After that, we built peptide-MHC (pMHC-I) models in HLA-arena, followed by hierarchical clustering analysis based on electrostatic surface features from each complex. We identified point mutations that are determinants for the presentation of a set of peptides from TP53 protein. We point to structural features in the pMHC-I complexes of wild-type and mutated peptides, which may play a role in the recognition of CD8 T cells. To further explore these features, we performed 100 ns molecular dynamics simulations for the peptide pairs (wt/mut) selected. In pursuit of novel therapeutic targets for GBM treatment, we selected peptides where our predictive results indicated that mutations would not disrupt epitope presentation, thereby maintaining a specific CD8 T cell immune response. These peptides hold potential for future GBM interventions, including peptide-based or mRNA vaccine development applications.

Nutritive tissue rich in reserves in the cell wall and protoplast: the case of Manihot esculenta (Euphorbiaceae) galls induced by Iatrophobia brasiliensis (Diptera, Cecidomyiidae).

The galls can offer shelter, protection, and an adequate diet for the gall-inducing organisms. Herein, we evaluated the structure of Manihot esculenta leaves and galls induced by Iatrophobia brasiliensis in order to identify metabolic and cell wall composition changes. We expected to find a complex gall with high primary metabolism in a typical nutritive tissue. Non-galled leaves and galls were subjected to anatomical, histochemical, and immunocytochemical analyses to evaluate the structural features, primary and secondary metabolites, and glycoproteins, pectins, and hemicelluloses in the cell wall. The gall is cylindric, with a uniseriate epidermis, a larval chamber, and a parenchymatic cortex divided into outer and inner compartments. The outer compartment has large cells with intercellular spaces and stocks starch and is designated as storage tissue. Reducing sugars, proteins, phenolic compounds, and alkaloids were detected in the protoplast of inner tissue cells of galls, named nutritive tissue, which presents five layers of compact small cells. Cell walls with esterified homogalacturonans (HGs) occurred in some cells of the galls indicating the continuous biosynthesis of HGs. For both non-galled leaves and galls, galactans and xyloglucans were broadly labeled on the cell walls, indicating a cell growth capacity and cell wall stiffness, respectively. The cell wall of the nutritive tissue had wide labeling for glycoproteins, HGs, heteroxylans, and xyloglucans, which can be used as source for the diet of the galling insect. Manihot esculenta galls have compartments specialized in the protection and feeding of the galling insect, structured by nutritive tissue rich in resource compounds, in the cell walls and protoplast.

Repercussões da Covid-19 na percepção de mudanças de peso e satisfação corporal: comparação entre mulheres com e sem transtornos alimentares / Impacts of Covid-19 on weight change perception and body satisfaction: a comparison between women with and without eating disorders

Introdução: A pandemia da Covid-19 trouxe consequências diversas para a saúde mental e física das pessoas. O contexto de isolamento social potencializou problemas relacionados à imagem corporal, principalmente em pessoas com transtornos alimentares. Objetivo: Analisar as repercussões da Covid-19 em variáveis antropométricas em relação a percepção de peso e satisfação corporal, comparando mulheres com transtornos alimentares e aquelas sem essa condição. Métodos: Estudo observacional, descritivo, comparativo e transversal. Mulheres com transtornos alimentares em tratamento (GTA) foram recrutadas de cinco serviços nas regiões Sul e Sudeste. A contrapartida, o grupo controle (GCO) foi composto por mulheres sem TA, recrutadas on-line e com o escore negativo no teste EAT-26. Questionários on-line foram aplicados entre junho de 2020 e janeiro de 2021. Análises estatísticas incluíram Qui-quadrado de Pearson ou Exato de Fisher e regressões logísticas pelo SPSS 23.0. Resultados: Participaram 174 mulheres jovens (31,94±9,35 anos), com formação superior (71,3%) e companheiro (61,5%), que estavam em isolamento social. O GTA foi composto por 58 mulheres e GCO, 116. A maioria (55,2%) do GTA notou aumento do peso corporal, enquanto se mostrou pouco satisfeita com a imagem corporal (81%), resultado diferente estatisticamente do GCO. A associação entre mulheres com TA e pouca satisfação corporal foi significativa (p=0,0010). Aquelas em isolamento social e com sobrepeso ou obesidade tiveram maior probabilidade de percepção de aumento de peso. Conclusão: A pandemia da Covid-19 intensificou a insatisfação corporal, principalmente entre mulheres com transtornos alimentares. Aquelas em isolamento com sobrepeso ou obesidade perceberam mais aumento de peso, apontando a necessidade de estratégias de intervenção para esses grupos.

Introduction: The Covid-19 pandemic led to various consequences for people's mental and physical health. The context of social isolation exacerbated problems related to body image, especially in individuals with eating disorders. Objective: To analyze the repercussions of Covid-19 on anthropometric variables regarding weight perception and body satisfaction, comparing women with eating disorders to those without this condition. Methods: Observational, descriptive, comparative, and cross-sectional study. Women with eating disorders in treatment (EDG) were recruited from five services in the South and Southeast regions of Brazil. The counterpart, the control group (CG), consisted of women without eating disorders recruited online and with a negative score on the EAT-26 test. Online questionnaires were applied between June 2020 and January 2021. Statistical analyses included Pearson's Chi-square or Fisher's Exact test and logistic regressions, performed using the SPSS 23.0 program. Results: Participants were 174 young women (31.94±9.35 years of age), with higher education (71.3%) and with a partner (61.5%), who were in social isolation. The EDG consisted of 58 women, with116 in the CG. The majority (55.2%) of the EDG noticed an increase in body weight while being dissatisfied with body image (81.0%), a statistically different result from the CG. The association between women with eating disorders and low body satisfaction was significant (p=.0010). Those in social isolation and overweight or obese were more likely to perceive weight gain. Conclusion: The Covid-19 pandemic intensified body dissatisfaction, especially among women with eating disorders. Those in isolation who were overweight or obese perceived more weight gain, indicating the need for intervention strategies for these groups.

O lugar de enunciação de bebês em sofrimento psíquico e com desfechos distintos de linguagem aos dois anos / El lugar de la enunciación de bebés con angustia psicológica y con diferentes resultados del lenguaje a los dos años / The enunciation place of babies in psychological distress and with different language outcomes at two years old / La place de l'énonciation des bébés en détresse psychologique et aux issues langagières différentes à deux ans

Este artigo analisa a singularidade linguística e psíquica de dois bebês com desfecho de linguagem distintos aos dois anos. Para análise utilizou-se a entrevista inicial e continuada, os Indicadores Clínicos de Referência/Risco ao Desenvolvimento Infantil (IRDI), os Sinais Enunciativos de Aquisição da Linguagem (SEAL), além de filmagens da interação entre mãe e bebê. Os resultados indicaram que apenas um dos casos houve superação do sofrimento psíquico e atraso na linguagem a partir do segundo ano de vida.

Epidemiological Profile of Ophir Loyola Cancer Hospital: A Snapshot of the Incidence of Solid Neoplasms in the Eastern Amazon.

BACKGROUND: Solid neoplasms have a heterogeneous incidence worldwide and in Brazil. Thus, the region delimited by the Legal Amazon has a distinct epidemiological profile. In Pará, Ophir Loyola Cancer Hospital(OLCH) accounts for 71.11% of hospital visits in the state. METHODS: This was an ecological, exploratory, and mixed descriptive studythat investigated the epidemiological profile of patients with cancer treated at OLCH from January to December 2020. Sociodemographic data at admission were the primary variables, which were analyzed according to spatial distribution. RESULTS: In this study, the data of 2952 patients were analyzed, with the majority being between the ages of 50 and 79 years (62.47%), female (59.49%), and diagnosed but without previous treatment (87.30%). The most common cancers were breast (16.50%), cervical (13.40%), stomach (8.98%), and prostate (7.72%). Of the 12 integration regions, Guajará had the highest number of referrals (49.86%), followed by Guamá (12.94%) and Caeté River (8.98%). CONCLUSION: The profile of care at OLCH showed a high incidence of solid malignancies compared to that in other regions of Brazil, indicating environmental and sociocultural influences on the carcinogenic profile present in the eastern Amazon.

Outstanding adsorption capacity of iron oxide synthesized with extract of açaí berry residue: kinetic, isotherm, and thermodynamic study for dye removal.

Contamination of water by toxic dyes is a serious environmental problem. Adsorbents prepared by an environmentally safe route have stood out for application in pollutant removal. Herein, iron oxide-based nanomaterial composed of Fe(III)-OOH and Fe(II/III) bound to proanthocyanidins, with particles in the order of 20 nm, was prepared by green synthesis assisted by extract of açaí (Euterpe oleracea Mart.) berry seeds from an agro-industrial residue. The nanomaterial was applied in the adsorption of cationic dyes. Screening tests were carried out for methylene blue (MB), resulting in an outstanding maximum adsorption capacity of 531.8 mg g-1 at 343 K, pH 10, 180 min. The kinetics followed a pseudo-second-order model and the isotherm of Fritz-Schülnder provided the best fit. Thermodynamic data show an endothermic process with entropy increase, typical of chemisorption. The proposed mechanism is based on the multilayer formation over a heterogeneous adsorbent surface, with chemical and electrostatic interactions of MB with the iron oxide nanoparticles and with the proanthocyanidins. The high adsorption efficiency was attributed to the network formed by the polymeric proanthocyanidins that entangled and protected the iron oxide nanoparticles, which allowed the reuse of the nanomaterial for seven cycles without loss of adsorption efficiency.

Constituição psíquica e linguística de um sujeito com transtorno do espectro do autismo imerso em uma família vulnerável pela imigração no pós-guerra / Psychic and linguistic constitution of a subject with autism spectrum disorder immersed in a family vulnerable by post-war immigration / Constitución psíquica y lingüística de un sujeto con trastorno del espectro autismo inmerso en una familia vulnerable por inmigración de posguerra

Introdução: este artigo apresenta a constituição psíquica e linguística de um jovem autista, proveniente de uma família de imigrantes em situação de pós-guerra, em que entram em questão temas como o luto, a constituição psíquica transgeracional, e a presença de angústias no processo de desenvolvimento da criança em uma situação singular que é a presença do autismo. Objetivo: analisar os efeitos singulares da imigração e multiculturalismo em um caso de autismo e sua evolução terapêutica. Método: estudo de caso longitudinal, que utilizou diário clínico e filmagens de sessões com observações do desenvolvimento de Rafael, desde os dezoito meses até a idade adulta. Como abordagem terapêutica e análise dos resultados, foram utilizados aportes da constituição psíquica da teoria psicanalítica, e sobre o desenvolvimento linguístico em uma perspectiva enunciativa. Resultados: O multiculturalismo acarretava um desafio maior ao processo de aquisição da linguagem por parte da criança com autismo, enquanto o silêncio consequente da dor do luto, presente nos adultos, dificultava a troca verbal e atrasava sua constituição psíquica. O autismo, por sua vez, apresentou-se como transtornos qualitativos na comunicação, necessitando maior investimento por parte de seus cuidadores para que a aquisição da linguagem se desse, pois o paciente precisou ser fisgado para a nossa cultura. Conclusão: Diante de todo esse quadro, o caso clínico demonstra a importância do suporte terapêutico à família e do investimento contínuo na subjetivação, considerando e valorizando os diferentes códigos culturais que compõem o núcleo familiar.

Introduction: this article presents the psychic and linguistic constitution of an autistic young man, from a post-war immigrant family, in which themes such as mourning, the transgenerational psychic constitution, and the presence of anxieties in the process come into question of the child development in a unique situation that is the presence of autism. Objective: to analyze the unique effects of immigration and multiculturalism in a case of autism and its therapeutic evolution. Method: longitudinal case study, which used a clinical diary and footage of sessions with observations of the development of R. from eighteen months to adulthood. As a therapeutic approach and analysis of results, contributions from the psychic constitution of psychoanalytic theory, and on linguistic development in an enunciative perspective, were used. Results: Multiculturalism posed a greater challenge to the process of language acquisition by the child with autism, while the consequent silence of the pain of grief, present in adults, hindered verbal exchange and delayed their psychic constitution. Autism, in turn, presented itself as qualitative disorders in communication, requiring greater investment on the part of its caregivers for the acquisition of language to take place, as it needed to be hooked for our culture. Conclusion: Given this situation, this clinical case demonstrates the importance of therapeutic support to the family and the continuous investment in subjectivity, considering and valuing the different cultural codes that make up the family nucleus.

Airway-delivered short-chain fatty acid acetate boosts antiviral immunity during rhinovirus infection.

BACKGROUND: Microbiota are recognized to play a major role in regulation of immunity through release of immunomodulatory metabolites such as short-chain fatty acids (SCFAs). Rhinoviruses (RVs) induce upper respiratory tract illnesses and precipitate exacerbations of asthma and chronic obstructive pulmonary disease through poorly understood mechanisms. Local interactions between SCFAs and antiviral immune responses in the respiratory tract have not been previously investigated. OBJECTIVE: We sought to investigate whether pulmonary metabolite manipulation through lung-delivered administration of SCFAs can modulate antiviral immunity to RV infection. METHODS: We studied the effects of intranasal administration of the SCFAs acetate, butyrate, and propionate on basal expression of antiviral signatures, and of acetate in a mouse model of RV infection and in RV-infected lung epithelial cell lines. We additionally assessed the effects of acetate, butyrate, and propionate on RV infection in differentiated human primary bronchial epithelial cells. RESULTS: Intranasal acetate administration induced basal upregulation of IFN-ß, an effect not observed with other SCFAs. Butyrate induced RIG-I expression. Intranasal acetate treatment of mice increased interferon-stimulated gene and IFN-λ expression during RV infection and reduced lung virus loads at 8 hours postinfection. Acetate ameliorated virus-induced proinflammatory responses with attenuated pulmonary mucin and IL-6 expression observed at day 4 and 6 postinfection. This interferon-enhancing effect of acetate was confirmed in human bronchial and alveolar epithelial cell lines. In differentiated primary bronchial epithelial cells, butyrate treatment better modulated IFN-ß and IFN-λ gene expression during RV infection. CONCLUSIONS: SCFAs augment antiviral immunity and reduce virus load and proinflammatory responses during RV infection.

Modulatory effect of myricitrin against chromosome instability and cytostasis induced by bleomycin and oxaliplatin in CHO-K1 cells.

Myricitrin (MYR), a flavonol consumed in the leaves and fruits of plants of the Myrtaceae family, presents anti-proliferative, anti-inflammatory, anti-diabetic, and antioxidant properties in humans. However, there are few studies regarding the cyto-genotoxicity and the chemopreventive potential of MYR. Using the in vitro Micronucleus test, the cytostasis, mutagenicity, and modulatory effect of MYR in CHO-K1 cells were assessed. The concentrations of 39 and 78 µg/mL (p < 0.001.) of MYR decrease the cytokinesis-block proliferation index (CBPI) in the short exposure treatment (4 h), while in the extended treatment (24 h), concentrations of 4.8, 9.7, 19.5, 39 and 78 µg/mL (p < 0.001.) decreased the CBPI. MYR associated with oxaliplatin decreased CBPI at all tested concentrations in the pre-(p < 0.001) and post-treatments (p < 0.001), but there was no decrease when associated with bleomycin. As for chromosome instability, MYR did not increase the frequency of micronuclei (MNi), nucleoplasmic bridges (NPBs), or nuclear buds (NBUDs) in the 4 h exposure time, however, in the 24 h treatment, MYR increased the frequency of MNi and NPBs at concentration 19.5 µg/mL (p < 0.001). As for the modulatory effect, MYR associated with bleomycin decreased the frequency of MNi, NPBs, and NBUDs at all concentrations in the pretreatment (MNi and NPBs p < 0.001, NBUDs p < 0.05) and simultaneously (MNi, NPBs and NBUDs p < 0.001). When associated with oxaliplatin, the simultaneous treatment decreased the frequency of MNi (p < 0.001) and NBUDs (p < 0.01) at all concentrations, however, in the post-treatment, MYR increased MNi (p < 0.001) and NPBs p < 0.05) in CHO-K1 cells, when compared to oxaliplatin alone. The results demonstrated that MYR could modulate the mutagenic and cytostatic actions of bleomycin and oxaliplatin, demonstrating distinct behaviors, depending on the mechanism of action of the chemotherapeutic agent.

Análise da relação entre eixos estruturantes na constituição do psiquismo e emergência de um lugar de enunciação de bebês com e sem atraso na aquisição da linguagem / Analysis of the relationship between structural pillars in the constitution of the psychism and the emergence of a place of enunciation in babies with and without delays in language acquisition

RESUMO Objetivo Analisar a correlação entre os eixos estruturantes do psiquismo no roteiro IRDI (Indicadores de Referência ao Desenvolvimento Infantil) e na aquisição da linguagem por meio dos Sinais Enunciativos de Aquisição da Linguagem (SEAL) quanto ao papel do bebê e da mãe nas protoconversações iniciais. Método A amostra contou com 77 bebês, que concluíram todas as avaliações no IRDI e no SEAL. Os resultados obtidos por meio desses dois instrumentos foram analisados por meio do coeficiente de Spearman e do teste de U de Mann-Whitney, considerando valor de p<= 0,05. Resultados Identificou-se correlação significativa entre as alterações nos indicadores relacionados à função materna (suposição de sujeito, estabelecimento da demanda e alternância presença/ausência) e as alterações nos sinais enunciativos dos bebês e das mães. Não houve correlação significativa na relação isolada do eixo função paterna e a presença de atraso na aquisição da linguagem. Conclusão Houve correlação significativa entre os eixos de função materna do roteiro IRDI e risco à linguagem pelo SEAL.

ABSTRACT Purpose To analyze the correlation between the psychism structuring pillar in the RIID (Reference Indicators of Infant Development) script and language acquisition through Enunciative Signs of Language Acquisition (ESLA) as to the role of the baby and the mother in early protoconversations. Methods The sample included 77 infants, who completed all the RIID and ESLA assessments. The results obtained from these two instruments were analyzed using Spearman's coefficient and the Mann-Whitney U test, considering a p-value < 0.05. Results A significant correlation was identified between changes in the indicators related to the maternal function (assumption of subject, establishment of demand and presence/absence alternation) and changes in the enunciative signals of babies and mothers. There was no significant correlation in the isolated relation of the paternal function pillar and the presence of delayed language acquisition. Conclusion There was a significant correlation between the pillars of maternal function of the RIID script and language risk by ESLA.

Tant l'exercice des fonctions parentales que les conditions des bébés sont des facteurs importants dans leur constitution psychique et linguistique, cequi amène d'importantes réflexions interdisciplinaires sur le caractère unique de la relation entre ces deux aspects du développement de l'enfant

Tratamento dos transtornos alimentares: perfil sociodemográfico, desfechos e fatores associados / Eating disorders treatment: sociodemographic profile, outcomes and associated factors

RESUMO Objetivo: Avaliar o perfil dos pacientes com transtornos alimentares (TAs) atendidos por um serviço especializado e investigar os fatores associados ao desfecho do tratamento. Métodos: Estudo retrospectivo, realizado com dados de pacientes com TAs que fizeram seguimento em um serviço especializado, desde a sua criação, em 1982, até 2019. Foram coletadas informações, nos prontuários médicos, referentes ao primeiro atendimento, de natureza sociodemográfica, clínica e antropométrica, e ao desfecho do tratamento. Resultados: Foram incluídos 271 pacientes. A amostra foi predominantemente do sexo feminino (89,7%), com idade média de 21,5 ± 9 anos, sem companheiro (86,9%) e diagnóstico de anorexia nervosa (AN) (65,7%), e o índice de massa corporal mais frequente foi de magreza (53,9%). A metade dos indivíduos tinha comorbidades psiquiátricas (50,6%), e 88,5% dos pacientes (n = 100) dos 113 prontuários com essa informação realizaram tratamento anterior. O tempo médio de tratamento foi de 2,16 ± 3,25 anos (1 mês a 40 anos). O abandono foi o desfecho terapêutico mais prevalente na amostra (68,3%). O maior tempo de tratamento e a realização de tratamento anterior reduziram a taxa de abandono, de forma significativa (p = 0,0001 e p = 0,0101, respectivamente). Para os pacientes com diagnóstico de transtorno de personalidade, a média de encaminhamento/inassistência foi 4,47 vezes maior (p = 0,0003). Conclusões: O perfil dos pacientes foi composto por mulheres adultas jovens, estudantes, sem companheiro, com AN, magreza e comorbidades psiquiátricas. A taxa de abandono foi elevada, e os fatores associados foram o tempo de tratamento e a realização de tratamento anterior. Além disso, transtornos de personalidade foram associados a encaminhamento para outro serviço e alta por inassistência.

ABSTRACT Objective: To evaluate the profile of patients with eating disorders (ED) treated by a specialized service and to investigate the factors associated with the treatment outcome. Methods: Retrospective study, with data from patients with ED who were followed up at a specialized service, since its creation, in 1982, until 2019. Information of a sociodemographic, clinical, anthropometric nature and the outcome of the treatment were collected from the medical records regarding the first consultation. Results: Two hundred and seventy one patients were included. The sample was predominantly female (89.7%), with a mean age of 21.5 ± 9 years, without a partner (86.9%), diagnosis of anorexia nervosa (AN) (65.7%) and the most frequent body mass index was thinness (53.9%). Half of the individuals had psychiatric comorbidities (50.6%) and 88.5% (n = 100) of the 113 medical records with this information had undergone previous treatment. The mean treatment time was 2.16 ± 3.25 years (1 month to 40 years). Dropout was the most prevalent therapeutic outcome in the sample (68.3%). Longer treatment time and having undergone previous treatment significantly reduced the dropout rate (p = 0.0001 and p = 0.0101, respectively). For patients diagnosed with a personality disorder, the mean referral/lack of assistance was 4.47 times higher (p = 0.0003). Conclusions: The patients' profile consisted of young adult women, students, single, with AN, thinness and psychiatric comorbidities. The dropout rate was high, and the predictors associated with this outcome were treatment time and previous treatment for ED. In addition, personality disorders were associated with referral to another service and discharge due to lack of assistance.

Relação entre sinais enunciativos de aquisição da linguagem e a avaliação de linguagem pela escala Bayley III aos 24 meses / Relationship between enunciative signs of language acquisition and language assessment through the Bayley III scale at 24 months

RESUMO Objetivo Analisar a correlação entre resultados obtidos no Sinais Enunciativos de Aquisição da Linguagem (SEAL) e na Escala Bayley III e comparar bebês com e sem atraso na aquisição da linguagem aos 24 meses no desempenho obtido por ele e sua mãe no SEAL dos 3 aos 24 meses. Método A coleta do SEAL constou de filmagens de 45 bebês, realizadas nas faixas etárias de 3 a 24 meses em interação com suas mães, com duração de 15 minutos, que foram avaliados por duas fonoaudiólogas treinadas no uso do SEAL. Aos 24 meses, os 45 bebês foram avaliados pela Escala Bayley III e selecionado o item linguagem para classificá-los com e sem atraso. Sobre tais resultados realizaram-se as análises estatísticas com o teste de correlação de Pearson e o teste exato de Fisher. Resultados Obtiveram-se as médias de sinais no desenvolvimento típico que foi 18 sinais e, em casos de atraso, a média foi de 12 sinais. Na comparação da relação de presença e ausência dos sinais entre os grupos com e sem atraso na aquisição da linguagem, oito sinais do bebê e um da mãe diferiram estatisticamente na amostra. O fator materno apresentou-se tão importante quanto o infantil na compreensão do funcionamento de linguagem dos bebês na análise realizada com o SEAL nos casos de atraso. Conclusão Houve correlação significativa entre o desempenho no SEAL entre 3 e 24 meses e o desfecho de linguagem aos 24 meses avaliado pela Escala Bayley III nesta amostra.

ABSTRACT Purpose To analyze the correlation between the results obtained on the SEAL and the Bayley III Scale and compare babies with and without delay in language acquisition at 24 months concerning the performance obtained by them and their mothers on the SEAL from 3 to 24 months. Methods The SEAL collection consists of 15-minute footages of 45 babies aged from 3 to 24 months old in interaction with their mothers, who were assessed by two trained speech therapists for the use of the SEAL. At 24 months, the 45 babies were assessed using the Bayley III Scale and the item language was selected to classify them with and without delay. These results were statistically analyzed through a Pearson's correlation test and a Fisher's exact test. Results In average, eighteen signs of typical development as we obtained, while a mean of 12 delay signs were found. By comparing the presence and absence of signs between the groups with and without delay in language acquisition, eight signs from the baby and one from the mother differed statistically in the sample. The analysis using the SEAL for cases of delay showed that the maternal factor was as important as the infant factor to understand the babies' language functioning. Conclusion There was a significant correlation between the SEAL performance from 3 to 24 months and the language outcome at 24 months assessed by the Bayley III Scale in this sample.

Evidence-based pharmacological prophylaxis recommendations for venous thromboembolism in hospitalized acutely ill medical patients: a systematic review of clinical practice guidelines / Recomendações baseadas em evidências científicas de profilaxia farmacológica para tromboembolismo venoso em pacientes hospitalizados com doenças agudas: uma revisão sistemática de diretrizes clínicas

Abstract Venous thromboembolism is a complex multifactorial disease considered the most common cause of preventable deaths in hospitalized patients. Recommendations about pharmacological venous thromboembolism prophylaxis in adult hospitalized patients are available in clinical practice guidelines for optimization of healthcare delivery and improvement of patient outcomes. We conducted a systematic review of clinical practice guidelines using ADAPTE to synthesize recommendations for pharmacological prophylaxis of venous thromboembolism in hospitalized medical patients at a medium complexity university hospital. Recommendations for pharmacological prophylaxis were extracted from seven clinical practice guidelines considered of high quality after assessment with the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. These recommendations will support discussion with specialists and implementation of practices in the setting of the hospital studied.

Resumo O tromboembolismo venoso é uma doença multifatorial complexa, considerada uma causa comum de óbitos evitáveis em pacientes hospitalizados. Recomendações sobre profilaxia farmacológica de tromboembolismo venoso em pacientes adultos hospitalizados estão disponíveis em diretrizes clínicas para otimizar os cuidados à saúde e contribuir com a melhora do desfecho do paciente. Dessa forma, foi conduzida uma revisão sistemática de diretrizes clínicas utilizando a metodologia ADAPTE para sintetizar as recomendações para profilaxia farmacológica de tromboembolismo venoso em pacientes clínicos adultos hospitalizados em um hospital universitário de média complexidade. As recomendações para profilaxia farmacológica foram extraídas de sete diretrizes clínicas consideradas de alta qualidade após avaliação pelo Appraisal of Guidelines for Research and Evaluation (AGREE II). Essas recomendações servirão de apoio para discussão com especialistas e implementação de práticas dentro do contexto do hospital estudado.

Immunomodulatory activity of trifluoromethyl arylamides derived from the SRPK inhibitor SRPIN340 and their potential use as vaccine adjuvant.

The serine/arginine-rich protein kinases (SRPK) specifically phosphorylate their substrates at RS-rich dipeptides, which are abundantly found in SR splicing factors. SRPK are classically known for their ability to affect the splicing and expression of gene isoforms commonly implicated in cancer and diseases associated with infectious processes. Non-splicing functions have also been attributed to SRPK, which highlight their functional plasticity and relevance as therapeutic targets for pharmacological intervention. In this sense, different SRPK inhibitors have been developed, such as the well-known SRPIN340 and its derivatives, with anticancer and antiviral activities. Here we evaluated the potential immunomodulatory activity of SRPIN340 and three trifluoromethyl arylamide derivatives. In in vitro analysis with RAW 264.7 macrophages and primary splenocytes, all the compounds modulated the expression of immune response mediators and antigen-presentation molecules related to a tendency for M2 macrophage polarization. Immunization experiments were carried out in mice to evaluate their potential as vaccine immunostimulants. When administrated alone, the compounds altered the expression of immune factors at the injection site and did not produce macroscopic or microscopic local reactions. In addition, when prepared as an adjuvant with inactivated EHV-1 antigens, all the compounds increased the anti-EHV-1 neutralizing antibody titers, a change that is consistent with an increased Th2 response. These findings demonstrate that SRPIN340 and its derivatives exhibit a noticeable capacity to modulate innate and adaptative immune cells, disclosing their potential to be used as vaccine adjuvants or in immunotherapies.

The SRPK inhibitor N-(2-(piperidin-1-yl)-5-(trifluoromethyl)phenyl) isonicotinamide (SRPIN340) increases the immune response against metastatic melanoma in mice.

Cancers have a strong relationship with immune cells in their microenvironment, which significantly influences tumor proliferation and progression. Thus, pharmacological strategies that stimulate the immune system to combat tumor cells are promising for better therapeutic efficacy. Deregulated expression of the splicing regulatory serine arginine protein kinases (mostly SRPK1 and SRPK2) has been found in different cancer types, leading to the expression of isoforms related to tumor growth and metastasis. The microenvironment of melanoma exhibits a strong presence of immune cells, which significantly influences tumor progression, and around 50% of cutaneous melanoma patients benefit from targeted immunotherapy. Here, we analyzed human malignant melanoma single-cell gene expression data and observed that SRPK1/2 overexpression correlates with immune system pathway alterations. In further analysis, we observed an increased presence of immune cells in biopsies from mice bearing metastatic melanoma treated with SRPIN340, a well-known SRPK1/2 pharmacological inhibitor. Local treatments increased the expression of proinflammatory cytokines at the tumor lesions and the activity of the spleen, accompanied by reduced pulmonary metastasis foci, edema formation, and alveolar congestion. In in vitro assays, SRPIN340 also potentiated immunological susceptibility, by increasing the expression of the antigen presenting MHCI and MHCII molecules and by increasing the ability of B16F10 cells to attract splenic cells in transwell assays. Taken together, these results reveal that the antimetastatic effect of SRPIN340 can also involve an increased immune response, which suggests additional functional clues for SRPKs in tumor biology.

Simultaneidade de comportamentos de risco para saúde e fatores associados na população brasileira: dados da Pesquisa Nacional de Saúde - 2013 / Simultaneity of health risk behaviors and associated factors in the Brazilian population: data from the National Health Survey - 2013

Resumo Introdução As doenças crônicas não transmissíveis (DCNT) apresentam origem multifatorial e entre os fatores de risco predisponentes a elas estão os comportamentos relacionados ao estilo de vida. Esses comportamentos poucas vezes ocorrem de maneira isolada, sendo a simultaneidade um fator agravante para o desenvolvimento de DCNT. Objetivo Estimar a ocorrência simultânea de comportamentos de risco para saúde e fatores associados na população brasileira. Método Utilizaram-se dados da Pesquisa Nacional de Saúde realizada em 2013. Os comportamentos de risco foram: tabagismo, consumo abusivo de bebidas alcoólicas, consumo irregular de frutas, legumes e verduras, tempo excessivo de TV e inatividade física. A presença de cada comportamento foi somada para obter a simultaneidade. As variáveis independentes analisadas foram: sexo, faixa etária e nível de escolaridade. Utilizou-se o teste do qui-quadrado para avaliar os fatores associados à ocorrência simultânea e a regressão logística para a associação entre os comportamentos de risco à saúde avaliados. Resultados Os comportamentos de risco mais frequentes foram: inatividade física (68,5%), consumo irregular de frutas, legumes e verduras (32,9%) e tempo excessivo de TV (28,9%). Quatro em cada dez indivíduos estavam expostos a dois comportamentos de risco simultaneamente. A ocorrência de três ou mais comportamentos de risco foi mais frequente entre os homens adolescentes e adultos quando comparados aos idosos, e houve redução gradual da frequência com o aumento da escolaridade. Conclusão Foi elevada a frequência de ocorrência simultânea de comportamentos de risco para saúde, a qual pode comprometer as condições de saúde da população brasileira.

Abstract Background Chronic non-communicable diseases (NCDs) have a multifactorial origin and lifestyle-related behaviors are among the predisposing risk factors. These behaviors seldom occur in isolation, and the simultaneity is an aggravating factor for the development of NCDs. Objective To estimate the simultaneous occurrence of health risk behaviors and associated factors in the Brazilian population. Method Data from the National Health Survey conducted in 2013 were used. The risk behaviors evaluated were smoking, abusive alcoholic beverage consumption, irregular consumption of fruits and vegetables, excessive screen time, and physical inactivity. The presence of each behavior was added to obtain simultaneity. The independent variables analyzed were gender, age group, and education level. The chi-square test was used to assess factors associated with simultaneous occurrence and logistic regression for the association between the health risk behaviors assessed. Results The most frequent risk behaviors were physical inactivity (68.5%), irregular consumption of fruits and vegetables (32.9%), and excessive screen time (28.9%). Four out of ten individuals were exposed to two risk behaviors simultaneously. The occurrence of three or more risk behaviors was more frequent among males, adolescents, and adults, compared to the elderly, and there was a gradual reduction with the increase in the education level. Conclusion The frequency of simultaneous occurrence of health risk behaviors was elevated, which may compromise the health conditions of the Brazilian population.

Combined therapy with cisplatin and 5-AZA-2CdR modifies methylation and expression of DNA repair genes in oral squamous cell carcinoma.

The methylation and expression of DNA repair system genes has been studied in several tumor types. These genes have been associated with resistance to chemotherapy treatments by epigenetic regulation. Studies have yet to show the effects of combined therapy using an epigenetic drug (5-aza-2CdR) and cisplatin (CDDP) on DNA repair genes in oral squamous cell carcinoma (OSCC). This study proposed to investigate the effects of CDDP in combination with 5-aza-2CdR on the methylation of MGMT and MLH1 genes in oral cancer cells. Oral squamous cell carcinoma cell lineages (SCC-9, SCC-15, and SCC-25) were submitted to 72 hours of treatment: 0.1 µM CDDP (or 4.44 µM SCC-9), 0.1 µM and 0.3 µM 5-aza-2CdR (or 1 µM and 3 µM SCC-9), and the drugs in combination. Cell viability was assessed by MTT, DNA methylation of MGMT and MLH1 genes by Methylation Sensitivity High-Resolution Melting (MS-HRM), and the relative expression of the genes by RT-qPCR. The results show that all treatments reduced cell viability; however, in SCC-15 and SCC-9 (IC50 value), 5-aza-2CdR promotes cell sensitization to cytotoxic effect of cisplatin. The MGMT promoter region was 100% demethylated in the SCC-15 and SCC-25 cells but partially (50%) methylated in SCC-9 before drug treatment. Treatment with IC50 CDDP value kept the methylation status and decreased MGMT expression in SCC-9; MGMT gene in SCC-15 and SCC-25 cells became downregulated after treatment with 5-aza-2CdR. MLH1 was demethylated, but the treatments with low-doses and combined drugs decreased the expression in SCC-9 and SCC-25; however high doses of 5-aza-2CdR and drug combination with IC50 value CDDP increased expression of MLH1 in SCC-9. The data presented suggest that epigenetic drugs associated with chemotherapy have clinical translational potential as a therapy strategy to avoid or reverse cancer resistance, requiring further investigation.
