ABSTRACT Objective: To describe the first known case of human Bertiellosis in Paraná (Brazil). Case description: A 6-year-old male residing in the Brazilian state of Paraná was suffering from intermittent nonspecific abdominal pain and abdominal distension, associated with expulsion of live tapeworms in his feces for 7 months. He had a history of interaction with monkeys on an island. His first feces analysis was inconclusive, with an initial hypothesis of an atypical Taenia. However, after additional research, the parasitologist identified pregnant proglottids of Bertiella sp. The patient was initially treated with an unknown dosage of albendazole and nitazoxanide, as it was believed he had been infected with Taenia sp. Since the symptoms persisted, praziquantel 10 mg/kg was prescribed without further proglottids elimination. Comments: Human Bertiellosis is a rare zoonosis, with less than one hundred cases reported. However, it is a cause of chronic abdominal pain and should be kept as a differential diagnosis, especially in cases reporting recurrent tapeworm expulsion in feces and refractory treatment with albendazole.

RESUMO Objetivo: Descrever o primeiro caso conhecido de bertielose humana no Paraná, Brasil. Descrição do caso: Criança de seis anos do sexo masculino, residente no Paraná, Brasil, apresentava dor abdominal inespecífica intermitente e distensão abdominal, associadas à expulsão de helmintos vivos em suas fezes havia sete meses. Tinha um histórico de interação com macacos em uma ilha. Sua primeira análise de fezes foi inconclusiva, com hipótese inicial de uma Taenia atípica. No entanto, após pesquisas adicionais, o parasitologista identificou proglótides gravídicas de Bertiella sp. O paciente foi inicialmente tratado com uma dosagem desconhecida de albendazol e nitazoxanida, pois se acreditava que havia sido infectado por Taenia sp. Diante da persistência dos sintomas, foi prescrito praziquantel 10 mg/kg, sem mais eliminação de proglótides. Comentários: A bertielose humana é uma zoonose rara, com menos de cem casos relatados. No entanto, é uma causa de dor abdominal crônica e deve ser mantida como diagnóstico diferencial, principalmente nos casos que relatam expulsão recorrente de helmintos nas fezes e que são refratários ao tratamento com albendazol.

ABSTRACT Sweet syndrome is a rare type of neutrophilic dermatosis, characterized by an acute febrile picture with the appearance of painful erythematous papules and plaques on the skin, with accompanying peripheral neutrophilia, which improves with the use of corticosteroids. The case of a 22-year-old patient, with vitiligo as the underlying disease, is presented. She attended for a 1-week history of ungraded feverish sensation and insidious appearance of lesions on photo-exposed skin. Laboratory and histopathological studies were carried out, leading to the diagnosis of Sweet syndrome. With the results of the paraclinical studies, treatment with systemic and topical corticosteroids was started with an excellent response.

RESUMEN El síndrome de Sweet es un tipo de dermatosis neutrofílica infrecuente, caracterizado por un cuadro febril agudo con aparición de lesiones en piel tipo pápulas y placas eritematosas y dolorosas, con neutrofilia periférica acompañante, que mejora con el uso de corticoides. Se presenta el caso de una paciente de 22 años, con vitíligo como enfermedad de base, que acude por un cuadro de 1 semana de evolución de sensación febril no graduada y aparición insidiosa de lesiones en piel foto expuesta. Se realizó estudios laboratoriales e histopatológicos llegando al diagnóstico de síndrome de Sweet. Con los resultados de los estudios paraclínicos se inició tratamiento con corticoides sistémicos y tópicos con excelente respuesta.

ABSTRACT Acne conglobata is a severe form of acne that produces many inflammatory lesions and scars, marking the patient's life in a negative way. We present the case of two brothers with acne conglobata, both with 2-year-old skin lesions with the appearance of nodules, cysts, and fistulas in extensive body territory. The first with a recent diagnosis of acute promyelocytic leukemia with plans to start chemotherapy and the second with no underlying pathologies. The first case received systemic antibiotic treatment due to infectious complications typical of immunosuppression, he also received dexamethasone and transretinoic acid as chemotherapy, and was discharged with the mentioned drugs and prophylactic antibiotic. The second case received treatment with systemic antibiotic and dapsone. Both cases returned for control at 2 months and significant improvement in skin lesions was observed. The first patient died due to complications inherent to his underlying pathology and the second patient abandoned treatment.

RESUMEN El acné conglobata es una forma severa de acné que produce muchas lesiones inflamatorias y cicatrices, marcando la vida del paciente de manera negativa. Presentamos el caso de 2 hermanos con acné conglobata, ambos con lesiones en piel de 2 años de evolución con aparición de nódulos, quistes y fístulas en territorio corporal extenso. El primero con diagnóstico reciente de leucemia promielocítica aguda en planes de iniciar quimioterapia y, el segundo, sin patologías de base. El primer caso recibió tratamiento antibiótico sistémico por complicaciones infecciosas propias de la inmunodepresión, además recibió dexametasona y ácido transretinoico como quimioterapia, y es dado de alta con dichos medicamentos y antibiótico profiláctico. El segundo caso recibió tratamiento con antibiótico sistémico y dapsona. Ambos acuden a control a los 2 meses y se observó mejoría importante de las lesiones en piel.

ABSTRACT Introduction: Chikungunya fever is characterized by fever, joint pain and skin rash. Paraguay in recent months has suffered an epidemic with significant morbidity and mortality. Many not only systemic but also cutaneous manifestations were very striking and are considered atypical of the disease. Objective: to communicate the various mucocutaneous manifestations in probable and confirmed cases of chikungunya fever. Metodology: prospective, descriptive and observational study of the mucocutaneous manifestations of chikungunya fever registered in the Servicio de Dermatología of the Hospital Nacional in the period February to April 2023. Patients of all ages and both sexes with the diagnosis confirmed by laboratory studies or probable by epidemiological link. Results: In this series of 58 patients, the maculopapular erythematous rash was the most frequent finding (41.3 %) followed by edema of the extremities (24.1 %). Vesico-bullous lesions were observed in 8 cases, all pediatric. Aphthoid lesions in the mouth and genitals, urticarial and purpuric lesions, acral and facial cyanosis, and acneiform eruption were other findings of interest, as well as exacerbation of previous dermatoses such as psoriasis and seborrheic dermatitis. Patterns of hyperpigmentation were observed in a small number of patients. A combination of lesions was observed in 28 patients. The diagnosis was confirmed in 44.8 % by means of the study of RT-PCR molecular techniques, 1 by ELISA with Positive Igm and the rest by epidemiological link. Conclusion: in our study, a wide variety of mucocutaneous manifestations was observed, with maculopapular rash being the most frequent manifestation, as well as manifestations considered atypical of the disease.

ABSTRACT Over the last decade, Zoltán Dörnyei’s L2 Motivational Self-System (L2MSS) theoretical framework has been used to explore the relationship between successful second language learning and learner motivation in a myriad of language learning contexts. However, not many studies have been carried out in developing countries. Through the lens of L2MSS’s three main components: Ideal L2 self, Ought to L2 self, and Learning experience, this study explores Language Learning Motivated Behavior (LLMB) in an Ecuadorian EFL setting. The article is part of a university research project. One hundred twenty-eight senior high school students completed a questionnaire drawn from previous research studies on the L2MSS. The results confirm that the Ideal L2 Self is a strong predictor of language learning motivation in Ecuador, validating this component as one of the highest-order motivational forces across different populations of L2 learners. Concerning its counterpart, the Ought to L2 self, it was not found a significant correlation between this variable and the criterion measure (LLMB), determining that the external force of the L2MSS presents socio-cultural variances. The Learning experience component also has a noticeable impact on motivated behavior in the context of the study.

RESUMEN Durante la última década, la teoría: ‘L2 Motivational Self-system’ (L2MSS ) de Zoltán Dörnyei se ha utilizado para explorar la relación entre el aprendizaje exitoso de un segundo idioma y la motivación del alumno en diversos contextos de aprendizaje de idiomas. Sin embargo, hay pocos estudios en países en desarrollo. Analizando los tres componentes principales del L2MSS: Ideal L2 self, Ought to L2 self y Learning experience, este estudio explora el comportamiento motivacional en el aprendizaje de idiomas en un contexto de inglés como lengua extranjera en Ecuador. Este artículo es parte de un proyecto de investigación universitario. 128 estudiantes de secundaria completaron un cuestionario extraído de estudios de investigaciones anteriores sobre el L2MSS. Los resultados confirman que el Ideal L2 self es un fuerte predictor de la motivación para el aprendizaje de idiomas en Ecuador, lo que valida este componente como una de las fuerzas motivacionales de más alto orden en diferentes poblaciones de estudiantes de lengua extranjera. En el Ought to L2 self no se encontró una correlación significativa entre esta variable y la variable dependiente, determinando que la fuerza externa de la L2MSS presenta variaciones socioculturales. El componente Learning experience también presenta un impacto notable en el comportamiento motivacional en el contexto de estudio.

Abstract Vegetable dietary protein sources are cheaper alternatives to fishmeal in shrimp diets. This study assessed the impact of fermented and non-fermented soybean and canola meals on growth performance, in vivo and in vitro digestibility, digestive enzyme activities and meat quality of Litopenaeus van-namei. A total of 513 shrimps were randomly assigned to treatments (control and two experimental diets). Animals on the control diet (CD) were fed a commercial feed concentrate. For the other treatments, the fishmeal protein source was totally replaced by a mixture of soybean and canola meal (50:50), either unfermented (SC) or fermented (FSC). Results showed that fermentation significantly increased (P < 0.05) the hydrolysis degree (HD) of SC meals by 12 % compared to that of their unfermented counterparts. Also, it was found that canola meal had higher HD compared to soybean meal, both before and after fermentation. The use of SC diet decreased protein digestibility in shrimps (P < 0.05), although there was no significant variation in the activity of total proteases and chymotrypsin. Production performance traits of shrimps fed diets with FSC were comparable to those of shrimps on the control diet. The increase in shear force of shrimps fed FSC was accompanied by an increase in the water holding capacity (WHC) by 8-9 % (P < 0.05). Sensory attributes were similar across diets. In summary, this study showed it is possible to fully replace fish meal with FSC in shrimp diets without impairing production performance traits, dietary protein digestibility, and shrimp meat quality.

Resumo Este artigo é fruto de resultados preliminares de uma pesquisa em andamento com motoristas por aplicativo e tem por objetivo discutir sobre como tem se dado o jogo de forças nas relações que se estabelecem entre as empresas, os trabalhadores, os órgãos reguladores e a sociedade. O estudo exploratório, com abordagem qualitativa, utilizou análise documental, questionário e entrevistas semiestruturadas com motoristas ligados a associações do Rio de Janeiro/RJ. Tendo como base o referencial teórico-metodológico da Ergologia, e a partir dos espaços micro e macroscópico da vida social, a análise se deu em uma perspectiva tripolar, abarcando os polos referentes à atividade humana, ao mercado e à política. Os resultados apresentam normas antecedentes que vêm sendo construídas sobre este trabalho na relação com as empresas, com os passageiros e entre os próprios motoristas, além de questões trazidas a partir da pandemia de COVID-19. Conclui-se ser necessário não contrapor a evolução tecnológica à conquista de direitos e da saúde dos trabalhadores, sendo imperativo lembrar que nenhuma ação que vise garantir a conciliação entre saúde, trabalho e direitos conseguirá avançar sem contar com uma dinâmica frutífera, e tendencialmente equilibrada, entre os três polos mencionados.

Abstract This paper is the product of an ongoing research’s preliminary results with app drivers and aims to discuss how the game of forces has occurred in the relationships established between companies, workers, regulatory bodies, and society. This exploratory qualitative study employed document analysis, a questionnaire, and semi-structured interviews with drivers linked to associations in Rio de Janeiro (RJ), Brazil. The analysis was conducted from a tripolar perspective based on the theoretical-methodological framework of Ergology and social life’s micro and macroscopic spaces, encompassing the poles referring to human activity, the market, and politics. The results show a background of norms built on this work about the relationship with companies, passengers, and the drivers themselves, besides issues raised from the COVID-19 pandemic. We can conclude that it is necessary not to counteract technological evolution to achieve workers’ rights and health. We should recall that no action aimed at ensuring the reconciliation of health, work, and rights will advance without relying on a fruitful and balanced trend between the three poles mentioned.

Resumen Este artículo analiza, en una perspectiva situada, las normas antecedentes que afectan el trabajo de los conductores y repartidores que trabajan a través de aplicaciones, con el fin de discutir las implicaciones de estas formas actuales de control y gestión algorítmica del trabajo. También busca identificar elementos de acción colectiva que se refieren a la movilización y construcción de reservas de alternativas. Desde la perspectiva ergológica, el método de investigación se basó en Encuentros del Trabajo, precedido de análisis documental, cuestionarios y entrevistas. Los resultados apuntan a las demandas y desafíos que impone este modo de gestión, así como a las renormatizaciones realizadas en la construcción de reservas de alternativas, entre ellas, el establecimiento de redes de sociabilidad. También se discute cómo la ausencia de regulación estatal y la sofisticada y compleja tecnología incorporada por las empresas de plataforma puede contribuir a profundizar el proceso de inseguridad social y la explotación de los trabajadores.

Resumo Este artigo analisa, em uma perspectiva situada, as normas antecedentes que incidem no trabalho de motoristas e entregadores que atuam por aplicativos, a fim de discutir as implicações dessas formas atuais de controle e gerenciamento algorítmico do trabalho. Busca também identificar elementos do fazer coletivo que remetam à mobilização e à construção de reservas de alternativas. A partir da perspectiva ergológica, o método de pesquisa baseou-se em Encontros sobre o Trabalho, precedidos de análise documental, questionários e entrevistas. Os resultados apontam para exigências e desafios impostos por esse modo de gerenciamento, assim como, para as renormatizações efetuadas na construção de reservas de alternativas, dentre elas, o estabelecimento de redes de sociabilidade. Discute-se ainda sobre como a ausência de regulação estatal e a sofisticada e complexa tecnologia incorporada pelas empresas-plataforma podem contribuir para o aprofundamento do processo de precarização social e exploração dos trabalhadores.

Résumé Cet article analyse, dans une perspective située, les normes antécédentes qui affectent le travail des chauffeurs et des livreurs opérant à travers des applications mobiles, afin de mettre en débat les conséquences de ces formes actuelles de contrôle et de gestion algorithmique du travail. Il cherche également à identifier des éléments d'action collective qui se réfèrent à la mobilisation et à la construction de réserves d'alternatives. Ancrée dans l’approche ergologique, la méthode de recherche est celle des Groupes de Rencontres du Travail, tout en ayant été précédée d'analyses de documents, de questionnaires et d'entretiens. Les résultats mettent en évidence les exigences et les défis imposés par ce mode de gestion, ainsi que les renormatisations effectuées dans la construction de réserves d'alternatives, parmi lesquelles la mise en place de réseaux de sociabilité. Il examine également comment l'absence de régulation au niveau de l’Etat et la technologie sophistiquée et complexe incorporée par les entreprises-plateforme contribuent à l'aggravation du processus de précarité sociale et d'exploitation des travailleurs.

Abstract This article analyzes, in a situated perspective, the antecedent norms that affect the work of platform drivers and food delivery couriers who work using on-demand apps, in order to discuss the implications of these current forms of control and algorithmic management of work. It also seeks to identify elements of collective action that refer to the mobilization and construction of reserves of alternatives. From the ergological perspective, the research method was based on Meetings about the Work, preceded by documentary analysis, questionnaires, and interviews. The results point to demands and challenges imposed by this management method, as well as to the renormatizations carried out in the construction of reserves of alternatives, and, among them, the establishment of sociability networks. It also discusses how the absence of state regulation, as well as the sophisticated and complex technology incorporated by the platform companies can contribute to deepening the process of social insecurity and exploitation of workers.

Resumen Los efectos de las sustancias químicas cuando se consideran contaminantes son de gran interés ya que se traducen como alteraciones de la funcionalidad de los órganos o sistemas en los seres vivos, los organismos son muy sensibles a la presencia de elementos exógenos provenientes de la contaminación ambiental. En esta investigación abordamos el estudio de la eliminación de cromo V1 por medio de la bacteria Rhodopseudomonas palustris cuando se aplica a aguas contaminadas. Los tratamientos de cromo VI (5 mg/L y 3 mg/L) se aplicaron en soluciones bacterianas (400 ml y 300 ml) durante períodos de 19 y 23 días en biorreactores. Se evaluó la eliminación del cromo VI por bacterias. Sobre la base de los resultados obtenidos, concluimos que el nivel de concentración de cromo VI se redujo por debajo de los límites máximos permisibles de 0,5 mg/L. Esta investigación demostró que los inóculos con bacterias tolerantes se pueden usar de manera eficiente para la eliminación de cromo con concentraciones características de efluentes industriales y mineros.

Abstract The effects of chemical substances when considered as pollutants are of major interest since they are translated as alterations of the functionality of organs or systems in living beings, organisms are very sensitive to the presence of exogenous elements coming from environmental pollution. In this Ínvestigation we boarded the study of the removal of chromium VI by means of the bacterium Rhodopseudomonas palustris when applied to contaminated waters. Chromium treatments (5 mg/L and 3 mg/L) were applied into bacterial solutions (400 mL and 300 mL) for times of 19 and 23 days periods in bioreactors. The elimination of chromium VI by bacteria was evaluated. On the basis of the results obtained we concluded that the level of concentration of chromium VI was reduced to below the máximum permissible limits of 0.5 mg/L. This research showed that inocula with tolerant bacteria can be used efficiently for the removal of chromium with characteristic concentrations of industrial and rnining effluents.

Abstract Ecological restoration through conventional plantation techniques can create forests with low biodiversity. As such, one way to overcome possible shortcomings of the restoration process is to use nucleation techniques, such as artificial perches. These structures attract the avifauna and increase the deposition of seeds associated with feces or bird regurgitation. Seed rain and seedlings regeneration were monitored under artificial perches and control areas in a degraded area of Rio de Janeiro, RJ, Brazil. In this study, 46 morphospecies of seeds were identified. Under the perches, greater abundance and richness of seeds were found with certain ecological and functional traits that support the role of artificial perches as a biological diversity core. Seedling establishment was low under the perches and control areas. This suggests that integrated actions to improve soil conditions should be applied to enhance seedling establishment.
