Review on the ethnomedicinal and nutritional value of some wild edible plants used by the tribal of Koraput District of Odisha, India
Authors: Jena Sameer , Dash Sudhansu Sekhar , Samal Ipsita Priyadarsini , Mahalik Gyanranjan
Published: July 2024

Due to its abundance of plant genetic resources, Odisha is often called a genetic refuge. However, the south Odisha tribal regions, despite their abundance of natural resources, have received scant ethnobotanical research. Human cultural diversity in Koraput is well-known, and the area is also a biodiversity hotspot for several food crops and forest species. The purpose of this study is to consolidate all available information on the ethnomedical uses of wild plants by indigenous peoples in the Koraput district. The reviewed nutritional analysis studies show that numerous species have high nutrient content, some of which are superior to some domesticated varieties. Wild edible plants are used as indigenous food and remarkably improve the nutritional security of several tribal people of Koraput. However, systematic study on the nutritional potential of these wild edible plants is meager. The present study evaluated the Carbohydrate, Fat, Protein, and Fiber content in selected wild edible plants of Koraput. Research shows that several species of tubers are in danger of extinction and hence included on the IUCN Red List of Threatened and Endangered Species. For this reason, the optimal use of this biodiversity is to meet the inhabitant's present and future food. The medicinal needs depend on extensive phytochemical inquiry, safe conservation, and sustainable use of wild tuber, all require strong community participation, which also fulfills the Sustainable Development Goals (SDG) 2 and 3, i.e., zero hunger and good health and well-being.

AI is not new. What is new, however, is the speed and depth of its expansion in almost every aspect of our lives. This discussion forum is dedicated to exploring new frontiers and agendas for language and intercultural communication research. In this concluding piece, we invite the contributors to share insights on five key questions: their experiences (Question 1), the challenges and opportunities that we face (Question 2), the strengths and skills afforded by intercultural communication and applied linguistics (Question 3), considerations when collaborating with AI developers and user groups (Question 4) and the future landscape of intercultural communication (Question 5). Through these inquiries, we hope to amplify the contributors’ voices and experiences, often difficult to fit in academic writing, but crucial for contextualizing their epistemological stances in their work. We seek to broaden the discussion, drawing out a bigger picture of pressing issues, and exploring future prospects.
Proposal of Cryptonemia floridana comb. nov. (Halymeniaceae, Rhodophyta) based on rbcL gene analysis of collections from type locality and female reproductive morphology
Authors: Soares Luanda Pereira , Guimarães Silvia M.P.B. , Sauvage Thomas , dos Santos Larissa A.H. , Fragoso Helena R. , Fujii Mutue T.
Published: July 2024

The taxonomic position of Halymenia floridana is a long-standing issue that needed to be assessed using DNA sequences of material from the type locality (Florida, USA). Here, we examined the vegetative and reproductive morpho-anatomy, and rbcL sequence data of topotypes and additional specimens from Brazil. Our results resolved the topotypes of ‘H. floridana’ within the genus Cryptonemia, in a clade harboring two closely related sister species, C. bermudensis and C. lacunicola. The rbcL haplotype of ‘H. floridana’ from Florida was also identical to previously and newly sequenced specimens from Brazil. Therefore, the new combination Cryptonemia floridana comb. nov. is herein established. Cryptonemia floridana exhibits entire to lobed foliose blades up to 12 cm high, a short basal midrib, medulla with conspicuous stellate ganglia and mostly periclinal filaments. The auxiliary cell is the first or the second cell of a third-order ampullar filament, and secondary connecting filaments are rare and cut off from the fusion cell. Our study is the first to provide the pre- and postfertilization stages in a Cryptonemia species, with generic status confirmed by DNA sequences. Numerous tropical Cryptonemia species await molecular confirmation and assessment of reproductive structures towards a better circumscription of the genus and its species diversity.
The implementation of a proposed deep-learning algorithm to classify music genres
Authors: Liu Lili
Published: July 2024

To improve the classification effect of music genres in the digital music era, the article employs deep-learning algorithms to improve the performance of the classification of music genres. An auxiliary (estimated) model is constructed to estimate the amount of unmeasured data in the dual-rate system to enhance the recognition effect of music features. Moreover, a dual-rate output error model to identify such impacts is proposed to eliminate the impact of corrupt data caused by the estimation, which eventually leads to the further improvement of the proposed model called dual-rate multi-innovation forgetting gradient algorithm based on the auxiliary model. In addition, the article employs linear time-varying forgetting factors to improve the stability of the system, advances the recognition effect of music features through enhancement processing, and combines a deep-learning algorithm to construct a classification system of music genres. The result shows that the classification of the music genre system based on a deep-learning algorithm has a good music genre classification effect.

Request for confirmation sequences in Korean
Authors: Kim Kyu-hyun
Published: July 2024

As part of a cross-linguistic investigation of request for confirmation (RfC) sequences, this article provides an overview of distributional tendencies associated with Korean RfC sequences based on an examination of 200 tokens of RfC excerpted from audio- and video-recorded face-to-face ordinary conversations. Various grammatical and contextual features associated with RfCs are analyzed, e.g., as interactional resources for grounding RfCs in inferencing, rendering them modulated in action, or connecting them to prior talk/action. They include negative polarity markers, connective particles (e.g., -nuntey ‘circumstantial’), modal markers (e.g., -keyss ‘I suppose’), and sentence-ending suffixes (SESs) such as -na (‘dubitative), -ney (‘noticing’), and ‘pseudo-tags’ -ci/cianha, which are composed of -ci (‘committal’). Features of responses to RfCs are examined in terms of response type (e.g., confirmation, disconfirmation, or neither) with special reference to the form and distribution of response tokens, which include not only unmarked interjections such as ung/yey (‘yes’) and ani(-yo) (‘no’), but also kule-marked indexical forms (e.g., ku(leh)ci ‘certainly it is’). The findings shed light on the role of SESs, modal markers, and discourse particles as stance-marking resources that crucially shape the function of RfCs, and the compositional features of response turns that constitute or frame a responsive action to RfCs.

À l’ère d’une pénurie de main-d’œuvre dans le réseau de l’éducation québécois, l’insertion professionnelle des personnes enseignantes non légalement qualifiées (PENLQ), grandissant en nombre, préoccupe. Dans ce contexte, un projet a vu le jour, ciblant notamment le rehaussement des qualifications de l’effectif enseignant par l’élaboration d’un modèle de reconnaissance des expériences et des acquis destiné aux PENLQ. Cet article présentera les étapes d’une démarche documentaire et conceptuelle menant à l’aboutissement de la proposition générique d’un Cadre de référence réflexif pour élaborer, implanter et évaluer un dispositif de reconnaissance d’acquis et de compétences, phase préliminaire d’une éventuelle modélisation.
Penser les parcours adultes à l’université : La VAE comme révélateur
Authors: Houot Isabelle
Published: July 2024

Les universités françaises mettent en œuvre, depuis 2002, une validation des acquis de l’expérience (VAE) certifiante, c’est-à-dire qui vise à délivrer intégralement un diplôme sur une base de reconnaissance des acquis expérientiels. Dans un contexte où les établissements universitaires sont largement incités à développer des parcours diplômants dits hybrides (combinant validation des acquis expérientiels et de formation), les débats propres à la manière de considérer les savoirs expérientiels au regard des finalités de l’université (produire et transmettre des savoirs, accompagner la professionnalisation des étudiants, etc.) ressurgissent. À partir d’une observation participante réalisée au sein d’un établissement engagé dans une recomposition de ses services dédiés à l’accueil des adultes en formation, cette contribution propose une lecture des différentes configurations dans lesquelles les agents professionnels transigent à la fois sur l’objet et la finalité de leurs activités communes pour produire et modéliser les dispositions propres à la VAE.

Published: July 2024

Cet article brosse un portrait de ce qui se fait en reconnaissance des acquis (RAC) en contexte autochtone au sein de deux universités, soit l’Université du Québec à Chicoutimi et l’Université du Québec en Abitibi-Témiscamingue. Il identifie aussi les potentialités et les obstacles envisagés pour mettre en place un modèle qui permettrait d’optimiser ce processus. En s’appuyant sur la recherche autochtone et la recherche collaborative, des rencontres ont eu lieu avec des professeurs, des professionnels ainsi que des partenaires et étudiants autochtones afin de relever les savoirs d’expérience de ces étudiants autochtones qui pourraient faire l’objet d’une démarche de RAC. La reconnaissance des compétences développées lors d’activités professionnelles extra formations et liées à la formation, la sécurisation culturelle, la valorisation et la reconnaissance des aspects personnels et communautaires d’une enseignante non légalement qualifiée doivent être pris en considération lorsqu’un processus de RAC est envisagé.

Authors: Manubulu Isakh Benyamin , Tahu Maria Filiana , Astariyani Ni Luh Gede , Da Cruz Rosino , Tuasikal Ditha Fomora
Published: July 2024

The exploration of Restorative Justice (RJ) in Indonesia's border areas, particularly within the context of North Central Timor High School, reveals intriguing insights into its implementation and reception among students. This study, employing an empirical legal research approach focused on statutory analysis, factual examination, and thoughtful analysis, sheds light on the evolving landscape of Indonesia's criminal justice system. Notably, the research highlights that while PERMENDIKBUD 46/23 initially adopts a distributive punishment framework, there exists a growing inclination towards adopting RJ principles. A significant proportion of students, constituting 55.50%, express strong support for the incorporation of RJ within the school environment. Moreover, a majority (51%) acknowledge the presence of RJ initiatives within their schools, emphasizing the gradual acceptance of this alternative approach. Furthermore, the findings underscore the importance of transparency in RJ practices, with 40% of students recognizing its significance. Additionally, a notable percentage (35.5%) of students endorse the application of RJ in addressing issues of sexual violence, signaling a potential avenue for addressing such sensitive matters within the school community. Crucially, a substantial proportion (43.33%) of students advocate for the active involvement of schools in facilitating the resolution of sexual violence cases through RJ processes. This underscores the pivotal role educational institutions can play in fostering a culture of accountability and restoration. Overall, the student perspectives elucidated in this research offer valuable insights into the feasibility and efficacy of RJ in addressing not only disciplinary matters but also complex issues like sexual violence within educational settings. As Indonesia continues to explore innovative approaches to justice, the embrace of RJ principles signifies a promising step towards fostering a more inclusive and restorative justice system.
Making Indonesia Sustainable: Shaping the Law to Reduce Digital Carbon Footprint
Authors: Puteri Dina Silvia
Published: July 2024

Indonesia needs to reduce the carbon footprint from the The Paris Agreement result, a legally binding international treaty on climate change, which entered into force on 4 November 2016. One of the outputs from the Paris Agreement is that the country needs to submit their national climate action plans, known as nationally determined contributions (NDCs). To achieve a sustainable future, Indonesia has Enhanced National Determined Contribution (ENDC) and committed to reducing its carbon emissions by 41 percent by 2030. This commitment is included in the Indonesia Emas 2045 (Golden Indonesia 2045) Program. However, the goals are still focusing on the physical carbon footprint. In the Indonesian Net Zero Emission Goals which needs to be achieved in 2060 the five steps mentioned are increasing the utilization of new renewable energy, reduction of fossil energy, the use of electric vehicles in the transportation sector, increasing electricity use in households and industry, and finally the utilization of Carbon Capture and Storage (CCS). Indonesia also needs to focus on reducing the digital carbon footprint as it currently increases with the usage of digital technologies.
The research questions discussed in this paper are how Indonesia currently regulates digital carbon footprint in Indonesia, and what can Indonesia do to reduce digital carbon footprint. This research aims to analyze the current condition and current regulation on digital carbon footprint in Indonesia, and how Indonesian government can learn from other countries to reduce the digital carbon footprint in Indonesia. Methodologies used in this research are normative approach and comparative approach. The output of this research is a regulation to reduce digital carbon footprint in Indonesia, and to regulate the business actors to create ESG reports on a company's sustainability.

Published: July 2024

Indonesian Government confronts a multifaceted challenge in repatriating former ISIS members, necessitating a delicate equilibrium between advocacy, citizenship status, and human rights principles. International conventions uphold the fundamental right to nationality, articulated in Article 15 of the Universal Declaration of Human Rights, yet over 500 former ISIS members from Indonesia remain stranded in Syria, having illegally departed and destroyed their official documentation.  While several countries in Southeast Asia and Europe have undertaken repatriation efforts under rigorous conditions, Indonesia faces a quandary. These individuals do not qualify as People with Social Welfare Problems under domestic law, complicating their reintegration. This classification divergence conflicts with international obligations requiring nations to accept and restore nationality to their citizens, notwithstanding their affiliation with extremist groups not recognized as refugees by the UNHCR. This paper delves into the legal and humanitarian imperatives compelling Indonesia to address this issue. It examines international frameworks and national legislation to argue for the necessity of repatriation, while also exploring the preventive and repressive measures Indonesia employs. Balancing the imperative to safeguard human rights with national security concerns presents a formidable task, demanding a nuanced approach that ensures compliance with international standards while safeguarding domestic stability and security.
Stripped of Rights: The Battle for Justice and Legal Certainty for Stateless Persons in Indonesia
Authors: Muhammad Muhammad
Published: July 2024

This research critically examines the justice system and legal certainty pertaining to stateless persons in Indonesia. Stateless individuals in Indonesia frequently encounter systemic discrimination and endure hardships due to inadequate legal protections. The study employs a normative juridical research approach, combining statutory analysis and conceptual exploration to assess the current regulatory framework. The findings underscore significant gaps in existing regulations that fail to adequately safeguard the rights of stateless persons. These individuals often struggle to access basic human rights such as education, healthcare, and employment, highlighting a critical need for legislative reforms. Legal certainty is a pivotal issue, as the ambiguity and inconsistencies within Indonesian laws contribute to the vulnerability of stateless populations. Furthermore, the research identifies discrepancies between national laws and constitutional mandates, which further complicate the legal landscape for stateless persons. This analysis aims to advocate for policy reforms that align with principles of justice and constitutional integrity, proposing measures to enhance legal protections and ensure equitable treatment for stateless individuals in Indonesia. By illuminating these challenges and proposing potential avenues for legal reform, this research seeks to contribute to broader discussions on human rights, migration, and legal justice within the Indonesian context, ultimately advocating for a more inclusive and just society for stateless persons

Published: July 2024

Indonesian limited liability company (Perseroan Terbatas or "PT") is a preferable entity selected by business actors in conducting activities. In this context, the characteristics of PT grant persona standi in judicio, as a legal subject capable of initiating and defending lawsuits in civil and criminal courts under Law No. 40 of 2007. Therefore, this article aimed to discuss the implementation of corporate accountability in the context of PT, and the potential for restorative justice in resolving disputes, relying on secondary sources such as theories, norms, and legal principles. The results show that 1) the application of restorative justice is consistent with the corporate entity's existence to maintain business continuity while upholding accountability as a legal subject, 2) Restorative Justice, centered on fundamental elements of encounter, repair, and transform, represents an effort towards the well-being and integrity of victims, perpetrators, and society. The method enhances legal certainty and protection for parties in PT-related business activities.

El discurso victimizador hacia los refugiados: estudio asistido por corpus de noticias sobre el movimiento de refugiados sirios
Authors: Soto Almela Jorge , Alcaraz Mármol Gema
Published: July 2024

Los conflictos internacionales de la última década han provocado la huida de miles de personas de sus países de origen a otros lugares, adoptando el estatus de refugiados o solicitantes de asilo. Este fenómeno migratorio ha sido ampliamente documentado en la prensa escrita española. Este artículo analiza un corpus de artículos periodísticos en español publicados entre 2010 y 2016 sobre el fenómeno de los refugiados sirios. Se tomaron como referencia los dos periódicos nacionales más leídos en España, El País y El Mundo, recopilando un corpus de más de 1,8 millones de palabras. A través de un enfoque CADS (estudios de discurso asistidos por corpus), nuestra investigación analiza especialmente cómo se construye la victimización del lema refugiado desde la perspectiva de la preferencia semántica. La victimización se desgrana en diferentes subconjuntos. Los resultados muestran que el lema refugiado coloca con términos victimizantes que expresan humanitarismo, desgracia y trato injusto, siendo el primer subconjunto el más común. El lenguaje humanitarista implica aparentemente una actitud positiva hacia los refugiados. Sin embargo, normalmente comporta un discurso asistencialista que refuerza las relaciones de poder entre los asistidos (refugiados) y los que los asisten (país de acogida).
Hydroxyapatite modified with polyhedral oligomeric silsesquioxane as a filler for dental resin-based composites
Authors: Buchwald Zuzanna , Buchwald Tomasz , Voelkel Adam
Published: July 2024

Hydroxyapatite modified with methacrylate groups-bearing polyhedral oligomeric silsesquioxane was for the first time applied as a filler in the experimental composite for dental applications. As the modifier changed the hydroxyapatite surface from hydrophilic to hydrophobic, it was predicted that the stability of the obtained composites would be improved in comparison with raw hydroxyapatite-filled composites. The stability in the oral imitating environment, basic physicochemical properties, and remineralizing potential understood as the ability to release calcium ions, were examined. The distribution of the fillers in the organic matrix, composites’ degree of conversion, depth of cure, flexural and compressive strengths, sorption, and solubility after 2 and 12 weeks of incubation, and the concentrations of calcium released were examined. The results were subjected to statistical analysis. The filler modification resulted in the improvement of the composites’ mass stability during long-term incubation with simultaneous beneficial more balanced calcium release profiles and comparable physicochemical properties.

This modification improved the haemocompatibility of the polymers through thrombin inhibition and reduced platelet aggregation and adhesion. Additionally, both modified polymers inhibited Staphylococcus aureus adhesion, growth and viability, confirming their acquired antibacterial properties. Antibacterial activity against Escherichia coli was also observed. These results demonstrate that modifying PVC and PU surfaces with copper (II) and AG produced materials with dual antithrombotic and antibacterial functions.

Composite solid electrolytes based on Li7La3Zr2O12 for all-solid-state lithium power sources
Authors: Ilyina Eugenia A. ,   Institute of High Temperature Electrochemistry of the Ural Branch of the Russian Academy of Sciences
Published: July 2024

Currently development of all-solid-state lithium batteries are in great demand all over the world. Li7La3Zr2O12 (LLZ) compounds are considered as perspective solid electrolyte for such power sources. However, these solid electrolytes of garnet family have some disadvantages – high temperatures of ceramic synthesis, poor wettability by Li and low stability to air components. The creation of composite solid electrolytes based on LLZ is one of the ways to solve these problems. It was established that the temperature and/or sintering time of the solid electrolyte could be reduced by the introduction of different additives with maintaining lithium-ion conductivity values (10–5–10–4 S/cm at room temperature). It should be noted that the used sintering additive should meet the following requirements: low softening temperatures, high values of lithium-ion conductivity, stability in contact with lithium metal and absence of chemical interaction between components leading to the formation of low-conductivity impurity phases. Thus, the development of composite solid electrolytes based on LLZ is perspective for all-solid-state power sources.

Published: July 2024

ABSTRACT: This study optimized the rheological parameters of doughs with partial substitution of wheat flour for blends of whole grain flours from germinated Andean pseudocereals such as quinoa (GQF), kiwicha (GKF), and cañihua (GCF) for bread production. The optimization was conducted through a Simplex-Centroid Mixture Design (SCMD) and Desirability Function (DF). Experiments were formulated using 80 to 90% wheat flour and 5 to 15% germinated pseudocereal blends. The rheological evaluation included farinograph, extensograph, and amylography analyses. Results showed that whole flour from germinated pseudocereals increases the water absorption, consistency, and extensibility of the doughs; and decreases its development time, stability, resistance to extensibility, temperature, and peak viscosity. The GQF-GKF blend developed more extensible and stable doughs, while GCF increased its consistency and was recommended for bread production. The data allowed us to obtain response surface models and the optimal substitution percentages to produce bread using GQF-GKF, GQF-GCF, and GKF-GCF blends.

RESUMO O objetivo deste artigo é discutir as crenças e percepções de doutorandos das áreas de Linguística, Literatura e História em relação ao conhecimento de gênero envolvidos na elaboração de projetos de tese submetidos a seleção para ingresso em curso de doutorado. A pesquisa se apoia nos pressupostos teóricos e metodológicos dos Estudos Retóricos de Gêneros (ERG), especialmente na visão de que os gêneros possuem uma realidade sociorretórica (MILLER, 1984; DEVITT, 2004) e sociocognitiva (BERKENKOTTER; HUCHIN, 2016; TSENG, 2012), a qual pode ser percebida através das expectativas genéricas e crenças dos usuários de um gênero específico. Em função de projetos de pesquisa, em geral, incluindo projetos de tese, caracterizarem-se como um gênero ocluso, as crenças e expectativas diferem bastante entre os doutorandos acerca das práticas de leitura e de escrita de projetos, tendo sido observadas formas um tanto inusitadas, não esperadas na literatura que tematiza práticas de leitura e escrita de deste gênero. Por outro lado, também reconhecemos crenças similares, como a percepção de que projetos de tese podem ser vistos como um “trampolim operacional e prospectivo” para o gênero tese de doutorado, de modo que o seu processo de elaboração envolve ações retórico-discursivas prospectivas para o desenvolvimento de ideias e ações esboçadas em termos de planejamento.

RESUMO Em diálogo com algumas perspectivas críticas das ciências humanas – notadamente, teoria econômica, história social, ciência política e sociologia da cultura – esse trabalho se alinha com uma revisão de antigas dicotomias e dualismos, incapazes de acompanhar as relações interculturais contemporâneas. Tendo como referências principais países como Brasil e China, aponta para outras possibilidades de exame do que se convencionou denominar “desigual e combinado” nas paisagens culturais atuais, em meio a crises socioambientais planetárias.

Abstract Producers of fish have been looking for viable alternatives for the management of Colossoma macropomum (tambaqui) in confinement systems in order to avoid the harm and subsequent losses caused by parasitic diseases. One alternative used by farmers is pesticides, such as trichlorfon, which has a genotoxic effect. Thus, this study aimed to evaluate the changes in gene expression due to the side effects of trichlorfon in tambaqui. Two treatments were used based on LC50-96h of 0.870 mg/L using 30% and 50% trichlorfon with exposure periods of 48, 72 and 96 h. For differential expression of the genes in the liver, real-time PCR was performed for the AChE, GST, CYP2J6, CYP2C8, 18S and GAPDH genes. After 96 h of exposure to trichlorfon, an alteration in the gene expression profile of the antioxidant defense system (GST) of the tambaqui was observed. It was also observed that this organophosphate did not affect the expression of genes related to the isoenzymes that are responsible for the biotransformation of xenobiotics in phase I (2J6 and 2C8) and cholinesterase AChE. It was concluded that the reduction in gene expression of GST suggests a decrease in metabolization capacity in phase II.

ABSTRACT Objective: To observe the therapeutic effect of gentiopicroside, as the main component of Gentianaceae, on wounds in pressure injury (PI) model rats and explore its mechanism. Method: Male Sprague Dawley rats were randomly divided into control group, model group and gentiopicroside groups (50, 100 and 200 mg·kg-1·d-1 for 9 consecutive days). The mice’s skeletal muscle fibroblast line NOR-10 cells were collected after being treated with gentiopicroside (0.2~5.0 M) and basic fibroblast growth factor receptor 1 (bFGFR1) inhibitor (5.0 M SU5402) for 7 days. Results: Compared to the model group, the gentiopicroside groups showed significantly increased wound healing rates, reduced inflammatory cells in the wound tissues, and significantly increased expression levels of proliferating cell nuclear antigen (PCNA) and bFGFR1, accompanied by increased proliferation of new myofibroblasts. Gentiopicroside upregulated the mRNA expression of bFGFR1 and PCNA in NOR-10 cells in a dose-dependent manner; however, SU5402 reversed the effect of gentiopicroside. Conclusion: Gentiopicroside may promote myofibroblast proliferation by upregulating the expression of bFGFR1 and PCNA and ultimately accelerating the healing of PI wounds.

Resumo Objetivo identificar, dentro dos três eixos de vulnerabilidades (individuais, sociais e programáticas), os fatores associados aos desfechos desfavoráveis do tratamento de tuberculose (TB) entre os idosos no Brasil entre 2015 e 2019. Método trata-se de um estudo transversal com dados secundários provenientes do Sistema de Informação de Agravos de Notificação dos casos de TB notificados no Brasil, em pessoas com idade igual ou maior que 60 anos. As co-variáveis associadas com o desfecho de interesse (p≤0,20) foram incluídas em um modelo de regressão logística multinomial utilizando a categoria cura como referência. Resultados idosos autodeclarados pretos e pardos, em situação de rua, com transtorno de saúde mental, que vivem com o vírus da imunodeficiência humana (HIV), que utilizam drogas lícitas e ilícitas tiveram maiores chances de perda de seguimento. Enquanto idosos em situação de rua, com transtorno de saúde mental, que utilizam drogas lícitas e ilícitas, e que não realizaram baciloscopia, apresentaram maiores chances para ocorrência de óbito por TB. Para o desfecho óbito por outras causas, pessoas que vivem com diabetes mellitus e com HIV, que utilizam drogas lícitas e ilícitas, tiveram maiores chances para ocorrência desse desfecho. Conclusão os resultados destacam a influência de fatores nos desfechos do tratamento da TB em idosos, abrangendo os eixos individual, social e programático. Aspectos como idade avançada, raça, sexo feminino, comorbidades e situação de rua foram identificados como determinantes relevantes, ressaltando a necessidade de abordagens integradas para melhorar os resultados e promover um desfecho favorável no tratamento da TB em idosos.

RESUMO Introdução: Já se reconhece que o incremento do potencial de aprendizagem dos alunos está diretamente relacionado às qualidades do preceptor. Nesse sentido, a avaliação da prática dos docentes impõe-se como um elemento essencial da garantia de qualidade na formação de novos especialistas. Todavia, no contexto da educação médica no Brasil, existem atualmente poucas pesquisas sobre avaliação de preceptores e escassez de instrumentos para essa finalidade. Um dos instrumentos atualmente disponíveis é o System for Evaluation of Teaching Qualities (SETQ). Objetivo: Este estudo teve como objetivo executar a adaptação transcultural e a validade de conteúdo do SETQ para uso no Brasil. Método: Esse instrumento é composto por duas versões, e neste estudo foi adaptada a versão dos residentes para avaliação do preceptor. A adaptação cultural seguiu cinco etapas: duas traduções iniciais do inglês para o português brasileiro; duas traduções de síntese; duas retrotraduções; uma avaliação do comitê de especialistas em termos de análise conceitual, equivalência semântica, idiomática e cultural; e um pré-teste. Além disso, um painel de juízes especialistas conduziu a validação de conteúdo. Resultado: Quarenta médicos residentes, com idade mediana de 30 anos (IQR = 6,25), participaram do pré-teste. Oitenta por cento dos participantes classificaram os componentes que compõem o SETQ Smart como claros e culturalmente apropriados, exceto pelo enunciado do questionário. O painel de juízes especialistas incluiu dez residentes, 70% do sexo feminino. As taxas de concordância variaram de 80% a 100% em relação à clareza, adequação cultural, representatividade dos itens dentro de seus respectivos domínios e permanência de cada item nas avaliações do instrumento. Conclusão: Este estudo adaptou culturalmente uma das duas versões do SETQ Smart para uso no Brasil e forneceu evidências preliminares de validade dessa versão por meio da validação de conteúdo.

ABSTRACT Objective: To identify and characterize the population of Pediatric patients referred to our hyperbaric oxygen therapy center. Methods: Retrospective and observational study, including pediatric patients treated with hyperbaric oxygen therapy, from 2006 to 2021, at the hyperbaric medicine reference center in the north of Portugal. Variables of interest were extracted from electronic medical records. Results: Our study included 134 patients. The most frequent reasons for referral were carbon monoxide poisoning (n=59) and sudden sensorineural hearing loss (n=41). In 75 cases (56%), treatment was initiated in an urgent context. Symptom presentation at Emergency Department varied among patients, the most frequent being headache and nausea/vomiting. Concerning carbon monoxide poisoning, the most common sources were water heater, fireplace/brazier, and boiler. Regarding adverse effects, it was identified one case of intoxication by oxygen and four cases of middle ear barotrauma. Conclusions: The most frequent cause for referral was carbon monoxide poisoning. All patients evolved favorably, with few side effects being reported, emphasizing the safety of this therapy. While most pediatricians may not be aware of the potential benefits arising with hyperbaric oxygen therapy, it is of upmost importance to promote them, so that this technique is increasingly implemented.

ABSTRACT Objective: This study aimed to compare the influence of four different maxillary removable orthodontic retainers on speech. Material and Methods: Eligibility criteria for sample selection were: 20-40-year subjects with acceptable occlusion, native speakers of Portuguese. The volunteers (n=21) were divided in four groups randomized with a 1:1:1:1 allocation ratio. The four groups used, in random order, the four types of retainers full-time for 21 days each, with a washout period of 7-days. The removable maxillary retainers were: conventional wraparound, wraparound with an anterior hole, U-shaped wraparound, and thermoplastic retainer. Three volunteers were excluded. The final sample comprised 18 subjects (11 male; 7 female) with mean age of 27.08 years (SD=4.65). The speech evaluation was performed in vocal excerpts recordings made before, immediately after, and 21 days after the installation of each retainer, with auditory-perceptual and acoustic analysis of formant frequencies F1 and F2 of the vowels. Repeated measures ANOVA and Friedman with Tukey tests were used for statistical comparison. Results: Speech changes increased immediately after conventional wraparound and thermoplastic retainer installation, and reduced after 21 days, but not to normal levels. However, this increase was statistically significant only for the wraparound with anterior hole and the thermoplastic retainer. Formant frequencies of vowels were altered at initial time, and the changes remained in conventional, U-shaped and thermoplastic appliances after three weeks. Conclusions: The thermoplastic retainer was more harmful to the speech than wraparound appliances. The conventional and U-shaped retainers interfered less in speech. The three-week period was not sufficient for speech adaptation.
