Achatina fulica infected by Angiostrongylus cantonensis on beaches, in the west zone of Rio de Janeiro, Brazil

Angiostrongylus cantonensis is considered the main etiological agent of eosinophilic meningitis in humans. At present, this zoonosis is considered an emerging disease mainly in the Americas. The aim of this study was to determine the prevalence of Achatina fulica infected by Angiostrongylus cantonensis in restinga areas along beaches in the west zone of Rio de Janeiro city, Brazil. The study areas included the following beaches: Barra da Tijuca, Recreio dos Bandeirantes, Reserva, Prainha and Grumari. Ninety specimens of Achatina fulica were collected. Positive molluscs were found only in Barra da Tijuca. Infection prevalence was 5.5%. The presence of this parasite in the beachfront areas, in the west zone of Rio de Janeiro city demonstrates the potential risk of infection for visitors and the expansion of this helminth in the State of Rio de Janeiro

Prevalência de Calodium hepaticum (sin. Capillaria hepatica) em Rattus norvegicus em área urbana do Rio de Janeiro, Brasil

O nematóide Calodium hepaticum (sin. Capillaria hepatica) é um helminto zoonótico encontrado infectando principalmente ratos. A prevalência da infecção de C. hepaticum em Rattus norvegicus foi investigada em área urbana do Rio de Janeiro (Brasil) com baixo planejamento e saneamento. A presença de C. hepaticum foi identificada através da presença de lesões macroscópicas caracterizadas por manchas extensas de coloração branco-amarelada difusa por toda superfície do tecido do fígado e através de análise histológica. A prevalência total da infecção foi de 45% sem diferença significativa entre o sexo e idade. A presença de roedores infectados próximos do peridomicílio representa um risco substancial para a saúde humana.The nematode Calodium hepaticum (syn. Capillaria hepatica) is a zoonotic helminth found mainly infecting rats. It was studied the prevalence of C. hepaticum infection in Rattus norvegicus in an urban area of Rio de Janeiro (Brazil), with low urban planning and sanitation. The presence of C. hepaticum was identified through visible yellowish-white lesions in liver tissue and histological analyses. The total prevalence of infection was 45%, with no significant differences between sex and age. The presence of infected rodents near the peridomestic area poses substantial risk to human health

Language and intercultural communication

This study intends to highlight the role that Foreign Language Education (FLE), particularly in the Higher Education context, can play so as to contribute to the rapprochement of two distant and still mutually unknown countries such as Portugal and Turkey. In this sense, it ultimately aims at supporting the training of intercultural speakers, capable of promoting an effective Intercultural Dialogue between the two countries. A diagnosis is presented of the reciprocal images of Portuguese and Turkish students learning each other’s language and culture. Conclusions are drawn on how their self- and hetero-images may pertain on the construction of their identities, on their awareness about and attitudes towards each other, on their motivation to learn each other’s language, and on intercultural communication itself. Allying the study of Images of Languages and Cultures and the concept of Intercultural Competence in the study of students’ representations within the FLE research tradition, a content analysis was carried out of the responses given to an inquiry by questionnaire. Conative implications of the students’ images as revealed in the results were pointed out. Some important distinctions are highlighted in the reciprocal images of both groups. On this basis, recommendations for FLE are made focusing on the positive reconstruction of students’ reciprocal images.Este estudo pretende destacar o papel do Ensino de Línguas Estrangeiras (ELE), no contexto do Ensino Superior, na aproximação de dois países distantes e ainda mutuamente desconhecidos como são Portugal e a Turquia. Visa-se, em última instância, fomentar a formação de falantes interculturais capazes de promover um efetivo Diálogo Intercultural entre os dois países. É feito um diagnóstico das imagens recíprocas de dois grupos de estudantes portugueses e turcos a estudarem a língua e a cultura um do outro. São tiradas conclusões sobre as implicações das respetivas auto- e hetero-imagens na sua construção identitária, conscientização e atitudes relativamente ao Outro, na sua motivação para o estudo da língua da sua contraparte e na própria comunicação intercultural. Com base na conjugação do conceito de Imagens de Línguas e Culturas com o conceito de Competência Intercultural no estudo das representações dos alunos na tradição investigativa em ELE, realizou-se uma análise de conteúdo das respostas a um inquérito por questionário, sendo apontadas as implicações conativas das imagens recíprocas dos participantes tal como as revelam os resultados. Com base nas diferenças observadas nas imagens recíprocas de ambos os grupos, são feitas recomendações relativamente à ELE com enfoque na reconstrução positiva destas imagens

Familial hypercholesterolaemia in children and adolescents from 48 countries: a cross-sectional study

Background: Approximately 450 000 children are born with familial hypercholesterolaemia worldwide every year, yet only 2·1% of adults with familial hypercholesterolaemia were diagnosed before age 18 years via current diagnostic approaches, which are derived from observations in adults. We aimed to characterise children and adolescents with heterozygous familial hypercholesterolaemia (HeFH) and understand current approaches to the identification and management of familial hypercholesterolaemia to inform future public health strategies. Methods: For this cross-sectional study, we assessed children and adolescents younger than 18 years with a clinical or genetic diagnosis of HeFH at the time of entry into the Familial Hypercholesterolaemia Studies Collaboration (FHSC) registry between Oct 1, 2015, and Jan 31, 2021. Data in the registry were collected from 55 regional or national registries in 48 countries. Diagnoses relying on self-reported history of familial hypercholesterolaemia and suspected secondary hypercholesterolaemia were excluded from the registry; people with untreated LDL cholesterol (LDL-C) of at least 13·0 mmol/L were excluded from this study. Data were assessed overall and by WHO region, World Bank country income status, age, diagnostic criteria, and index-case status. The main outcome of this study was to assess current identification and management of children and adolescents with familial hypercholesterolaemia. Findings: Of 63 093 individuals in the FHSC registry, 11 848 (18·8%) were children or adolescents younger than 18 years with HeFH and were included in this study; 5756 (50·2%) of 11 476 included individuals were female and 5720 (49·8%) were male. Sex data were missing for 372 (3·1%) of 11 848 individuals. Median age at registry entry was 9·6 years (IQR 5·8-13·2). 10 099 (89·9%) of 11 235 included individuals had a final genetically confirmed diagnosis of familial hypercholesterolaemia and 1136 (10·1%) had a clinical diagnosis. Genetically confirmed diagnosis data or clinical diagnosis data were missing for 613 (5·2%) of 11 848 individuals. Genetic diagnosis was more common in children and adolescents from high-income countries (9427 [92·4%] of 10 202) than in children and adolescents from non-high-income countries (199 [48·0%] of 415). 3414 (31·6%) of 10 804 children or adolescents were index cases. Familial-hypercholesterolaemia-related physical signs, cardiovascular risk factors, and cardiovascular disease were uncommon, but were more common in non-high-income countries. 7557 (72·4%) of 10 428 included children or adolescents were not taking lipid-lowering medication (LLM) and had a median LDL-C of 5·00 mmol/L (IQR 4·05-6·08). Compared with genetic diagnosis, the use of unadapted clinical criteria intended for use in adults and reliant on more extreme phenotypes could result in 50-75% of children and adolescents with familial hypercholesterolaemia not being identified. Interpretation: Clinical characteristics observed in adults with familial hypercholesterolaemia are uncommon in children and adolescents with familial hypercholesterolaemia, hence detection in this age group relies on measurement of LDL-C and genetic confirmation. Where genetic testing is unavailable, increased availability and use of LDL-C measurements in the first few years of life could help reduce the current gap between prevalence and detection, enabling increased use of combination LLM to reach recommended LDL-C targets early in life
