Self-care guidelines for patients in the post-hematopoietic stem cell transplantation period: a scoping review.

OBJECTIVE: To map the evidence on self-care guidelines for patients in the post-hematopoietic stem cell transplantation (HSCT) period. METHOD: Scoping review supported by Joanna Briggs Institute recommendations, with searches conducted between March and April 2022 in national and international databases and repositories of theses and dissertations. RESULTS: Of the 11 studies that composed the final sample, the guidelines had a social and personal aspect, as post-transplant patients need to follow numerous essential recommendations for the prevention of infections and complications for successful treatment and improved quality of life. CONCLUSION: Knowing the self-care guidelines that must be performed by post-HSCT patients is fundamental for the nursing team to provide the necessary information for care outside the controlled environment of the hospital, in addition to minimizing episodes of infection, death, and increasing the survival and quality of life of transplant recipients.

A scoping review on hyposalivation associated with systemic conditions: the role of physical stimulation in the treatment approaches.

BACKGROUND: Several systemic conditions can result in distinct degrees of salivary gland damage and consequent hypofunction. The development of successful management schemes is highly challenging due to the complexity of saliva. This study aimed to systematically map the literature on the physical stimulation of salivary glands for hyposalivation management and the response of individuals according to different systemic conditions causing salivary impairment. METHODS: A systematic search in the literature was performed. Two reviewers independently selected clinical trials, randomized or not, that used physical stimulation to treat hyposalivation caused by systemic conditions. Studies evaluating healthy subjects without hyposalivation were included as controls. Single-arm clinical studies or case series were also included for protocol mapping (PRISMA extension for scoping reviews). RESULTS: Out of 24 included studies, 10 evaluated healthy subjects, from which 9 tested transcutaneous electrical nerve stimulation (TENS) and 1 tested acupuncture and electroacupuncture. Fourteen studies evaluated individuals with hyposalivation: 6 applied TENS, 6 applied low-level laser therapy (LLLT), and 2 applied acupuncture, carried out in post-chemotherapy, medication use, postmenopausal women, hemodialysis patients, smokers, diabetics, Sjögren's syndrome (SS). All showed increased salivation after treatment, except for two LLLT studies in individuals with SS. CONCLUSIONS: Among the different patient groups, individuals with Sjögren's syndrome (SS) exhibited the poorest responses, while those with medication-induced hyposalivation demonstrated the most favorable treatment outcomes, independently of the management strategy for saliva stimulation. It means that physical stimulation of salivary glands holds promise as an alternative for managing hyposalivation in cases of reversible gland damage. However, to make informed decisions in current practice, it is necessary to conduct new well-designed randomized clinical trials with appropriate methodologies.

Clinical management of salivary gland hypofunction in patients with head and neck cancer: a scoping review of physical salivary stimulation methods.

OBJECTIVE(S): This scoping review aims to map the scientific literature on the therapies currently available for physical salivary stimulation in individuals with hyposalivation caused by radiotherapy. STUDY DESIGN: Studies were included when they comprised the target population of adult individuals receiving radiotherapy of the head and neck region and who developed or were at risk of developing hyposalivation. Two reviewers selected the studies and extracted data on the type of physical salivary stimulation therapy used, the degree of glandular tissue involvement, and the percentage of salivary flow alteration. Therapies were classified according to either prophylactic application (before/during radiotherapy) or therapeutic application (post-radiotherapy). RESULTS: Sixteen articles were included: 4 tested transcutaneous electrical nerve stimulation (TENS), 3 studied low-level lasers, 7 researched acupunctures, and 2 investigated acupuncture-like TENS. The outcomes of the prophylactic studies indicated beneficial effects (similar salivary flow or reduced salivary flow loss), although most studies did not include a comparable control group. Therapeutic studies presented conflicting results. CONCLUSION(S): Prophylactic therapies of physical salivary stimulation may produce better effects than therapeutic applications. However, the protocols best indicated could not be defined. Well-designed, controlled clinical trials should be researched in the future to support the clinical recommendation of any of these treatments.

In situ H2O2 treatment of blue-green algae contaminated reservoirs causes significant improvement in drinking water treatability.

The evaluation of water quality improvement brought about by in situ treatment of eutrophic water bodies, especially those used for human supply is a challenging task since each water system responds differently. To overcome this challenge, we applied exploratory factor analysis (EFA) to understand the effects of using hydrogen peroxide (H2O2) on eutrophic water used as a drinking water supply. This analysis was used to identify the main factors that described the water treatability after exposing blue-green algae (cyanobacteria) contaminated raw water to H2O2 at both 5 and 10 mg L-1. Cyanobacterial chlorophyll-a was undetectable following the application of both concentrations of H2O2 after four days, while not causing relevant changes to green algae and diatoms chlorophyll-a concentrations. EFA demonstrated that the main factors affected by both H2O2 concentrations were turbidity, pH, and cyanobacterial chlorophyll-a concentration, which are important variables for a drinking water treatment plant. The H2O2 caused significant improvement in water treatability by decreasing those three variables. Finally, the use of EFA was demonstrated to be a promising tool in identifying which limnological variables are most relevant concerning the efficacy of water treatment, which in turn can make water quality monitoring more efficient and less costly.

HIV and syphilis co-infection in northeast Brazil: a gender assessment / Coinfecção HIV e sífilis no Nordeste do Brasil: uma avaliação de gênero

Objective: this study aimed to determine the frequency and the clinical-epidemiological profile of the human immunodeficiency virus (HIV) and syphilis co-infection between genders in specialized care services in Northeast Brazil. Methods: an analytical cross-sectional study was conducted with secondary data from 171 individuals with HIV and syphilis co-infection. Data were collected in a reference center for acquired immunodeficiency syndrome (AIDS) in Northeast Brazil from 2015 to 2020. Welch's test compared the means of independent samples; the chi-square and Fisher's exact test assessed the association between categoric variables. The significance level was set at 5%. This study has ethical approval. Results: the HIV and syphilis co-infection frequency was 15.4%. Individuals with co-infection had a mean age of 34.2 (± 11.0) years and were predominantly men. The women sample started their sex life earlier, had a lower education level and per capita family income, used more illicit drugs, and were mostly heterosexual, married or in a stable union, and unemployed. Men had more anal sex. Moreover, most individuals had syphilis in the asymptomatic phase and HIV with undetectable viral load; CD4 T cells were greater than 350 cells/mm³. Conclusion: the high prevalence of HIV and syphilis co-infection in specialized care services, especially in men who have sex with men (MSM), highlights the need to improve counseling to reduce sexual risk behavior and improve prevention and care strategies to control these diseases.

Objetivo: este estudo teve como objetivo determinar a frequência e o perfil clínico-epidemiológico da coinfecção pelo vírus da imunodeficiência humana (HIV) e sífilis em ambos os gêneros num serviço de atenção especializada no Nordeste do Brasil. Métodos: trata-se de um estudo transversal, analítico, com dados secundários de 171 pacientes com coinfecção por HIV e sífilis de um centro de referência para síndrome da imunodeficiência adquirida (SIDA) de 2015 a 2020. O teste de Welch foi utilizado para comparar as médias de amostras independentes; os testes qui-quadrado e exato de Fisher avaliaram a associação entre variáveis categóricas. O nível de significância adotado foi de 5%. Este estudo obteve aprovação ética. Resultados: a frequência da coinfecção por HIV e sífilis foi de 15,4%. Os indivíduos tinham idade média de 34,2 (± 11,0) anos e eram predominantemente homens. As mulheres iniciaram a vida sexual mais cedo, tinham menor escolaridade e renda familiar per capita, usavam mais drogas ilícitas e eram, em sua maioria, heterossexuais, casadas ou em união estável, e desempregadas. Os homens praticavam mais sexo anal. A maioria dos indivíduos apresentava sífilis na fase assintomática e HIV com carga viral indetectável, além de células T CD4 superiores a 350 células/mm³. Conclusão: a alta prevalência de coinfecção por HIV e sífilis em serviços de atenção especializada, principalmente em homens que fazem sexo com homens (HSH), evidencia a necessidade de aprimorar o aconselhamento a fim de reduzir comportamentos sexuais de risco e melhorar as estratégias de prevenção e cuidado para o controle dessas doenças.

Preschoolers' cognitive-linguistic performance in different educational contexts / Desempenho cognitivo-linguístico de pré-escolares em diferentes contextos educacionais

ABSTRACT Purpose: to investigate preschoolers' cognitive-linguistic performance in different educational settings. Methods: thirty-nine children aged 4:0 to 5:11 years, enrolled in two private preschools from different Brazilian regions, were assessed with the Protocol for the Early Identification of Reading Problems, in the version adapted to preschool - which includes the following tests: alphabet knowledge; metaphonological skills; phonological working memory; rapid automatized naming; silent word reading; and hearing sentence comprehension based on figures. The groups were compared with the Mann-Whitney statistical test, and significant differences were set at p < 0.05. Results: as expected, data revealed different performances between preschoolers from the two schools. The worse results in both were related to rhyme production and rhyme identification, which reveals that phonological awareness is probably not being stimulated in these groups. Participants performed as expected or "under attention" in the other skills. Conclusion: the performances of preschoolers from both schools were identified and classified, revealing differences in cognitive-linguistic performances between the different educational settings. These results ratify the importance of a teaching approach that helps develop cognitive-linguistic skills, early in preschool.

RESUMO Objetivo: investigar o desempenho cognitivo-linguístico de pré-escolares em diferentes contextos educacionais. Métodos: participaram do estudo 39 crianças, com idades entre 4:0 e 5:11 anos, matriculadas na pré-escola de duas escolas particulares, localizadas em diferentes regiões brasileiras. Os pré-escolares foram avaliados por meio do Protocolo de Identificação Precoce de Problemas de Leitura - IPPL, na versão adaptada para a Educação Infantil, que inclui provas de: conhecimento do alfabeto; habilidades metafonológicas; memória operacional fonológica; nomeação automática rápida; leitura silenciosa de palavras e compreensão auditiva de sentenças a partir de figuras. Os grupos foram comparados por meio do teste estatístico Mann-Whitney, considerando-se significativas diferenças com p<0,05. Resultados: como esperado, os dados revelaram diferenças de desempenho entre os pré-escolares das duas escolas. Verificou-se que os piores resultados, em ambas as escolas, foram relacionados às habilidades de produção de rima e identificação de rima, o que revela que a consciência fonológica não deve estar sendo estimulada nesses grupos. Nas demais habilidades os participantes apresentaram desempenhos dentro do esperado ou sob atenção. Conclusão: foi possível identificar e classificar o desempenho dos pré-escolares de ambas as escolas, havendo diferenças no desempenho cognitivo-linguístico em diferentes contextos educacionais. Tais resultados ratificam a importância de uma abordagem de ensino que promova o desenvolvimento de habilidades cognitivo-linguísticas desde a Educação Infantil.

Percepção de professores sobre intervenção educativa de base fônica / Teachers' perception of phonic-based educational intervention

Além do domínio nas habilidades de consciência fonológica, o aprendizado da leitura e escrita exige o desenvolvimento de outras competências, como, por exemplo, o processamento visual, auditivo e fonológico. Tais habilidades devem ser conhecidas pelo professor alfabetizador, pois ele precisa reconhecer as crianças com dificuldades e buscar estratégias cognitivo-linguísticas para que elas avancem. OBJETIVO: Desvelar a percepção de professores sobre intervenção educativa de base fônica voltada à facilitação da aprendizagem inicial da leitura e escrita MÉTODO: Trata-se de estudo longitudinal, de intervenção, realizado com duas professoras do 2º ano do Ensino Fundamental I de uma escola pública da cidade do Recife, PE. Ambas participaram de uma intervenção educativa realizada com sua turma, em 12 encontros. Ao final de cada encontro, as professoras responderam três perguntas norteadoras sobre as atividades realizadas RESULTADOS: A análise de conteúdo possibilitou a identificação de quatro categorias temáticas: 1- Desafios da alfabetização; 2- Estratégias facilitadoras da aprendizagem da leitura e escrita; 3- Contribuições da intervenção para o processo de alfabetização; 4- Contribuições da intervenção para a identificação de crianças em risco para os transtornos de aprendizagem CONCLUSÃO: De acordo com as professoras, a intervenção foi positiva, contribuiu para o processo de facilitação da aprendizagem e possibilitou a identificação precoce de escolares em risco para transtornos de aprendizagem, sendo importante o desenvolvimento de estudos de intervenção de base fônica para auxiliar a prática docente no ciclo de alfabetização

In addition to mastering phonological awareness skills, learning to read and write requires the development of other skills, such as visual, auditory and phonological processing. Such skills must be known by the literacy teacher, as he needs to recognize children with difficulties in the literacy process, and seek cognitive-linguistic strategies for them to advance. PURPOSE: To unveil the perception of teachers about phonics-based educational intervention aimed at facilitating the initial learning of reading and writing METHODS: This is a longitudinal intervention study carried out with two teachers from the 2nd year of elementary school I of a public school in the city of Recife, Pernambuco state. Both participated in an educational intervention carried out with their class, in 12 meetings. At the end of each meeting, the teachers answered three guiding questions about the activities carried out RESULTS: Content analysis allowed the identification of four thematic categories: 1- Literacy challenges; 2- Facilitating strategies for learning to read and write; 3- Contributions of the intervention to the literacy process; 4- Contributions of the intervention to identify children at risk for learning disabilities CONCLUSION: According to the teachers, the intervention was positive, contributed to the process of facilitating learning and enabled the early identification of students at risk for learning disorders, being important the development of phonics-based intervention studies to help practice teacher in the literacy cycle

Evaluation of lipase access tunnels and analysis of substance transport in comparison with experimental data.

Lipases (E.C. 3.1.1.3) have buried active sites and used access tunnels in the transport of substrates and products for biotransformation processes. Computational methods are used to predict the trajectory and energy profile of ligands through these tunnels, and they complement the experimental methodologies because they filter data, optimizing laboratory time and experimental costs. Access tunnels of Burkholderia cepacia lipase (BCL), Candida rugosa lipase (CRL), and porcine pancreas lipase (PPL) and the transport of fatty acids, alcohols and esters through the tunnels were evaluated using the online server CaverWeb V1.0, and server calculation results were compared with experimental data (productivity). BCL showed higher productivity with palmitic acid-C16:0 (4029.95 µmol/h mg); CRL obtained productivity for oleic acid-C18:1 (380.80 µmol/h mg), and PPL achieved productivity for lauric acid-C12:0 (71.27 µmol/h mg). The highest probability of transport for BCL is through the tunnels 1 and 2, for CRL through the tunnel 1, and for PPL through the tunnels 1, 2, 3 and 4. Thus, the best in silico result was the transport of the substrates palmitic acid and ethanol and product ethyl palmitate in tunnel 1 of BCL. This result corroborates with the best result for the productivity data (higher productivity for BCL with palmitic acid-4029.95 µmol/h mg). The combination of in silico evaluation and experimental data gave similar results, demonstrating that in silico approaches are a promising alternative for reducing screening tests and minimizing laboratory time in the bio-catalysis area by identifying the lipases with the greatest reaction potential, as in the case of this proposal.

Sociodemographic, clinical, epidemiological and care aspects of children and adolescents treated for retinoblastoma in Brazil: a cross-sectional study / Aspectos sociodemográficos, clínicos, epidemiológicos e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil: estudo transversal

Introduction: Retinoblastoma greatly impacts the affected children and adolescents and their families. Epidemiological approaches to this form of cancer in Brazil are scarce, and this gap motivated this study. Objectives:This study aimed to describe the sociodemographic, clinical, epidemiological, and care characteristics of children and adolescents treated for retinoblastoma in Brazil and analyze whether there is any association between them. Methods: It is a cross-sectional, descriptive-analytical study, carried out with accompanying family members of children and adolescents treated for retinoblastoma in Brazil, sampled by snowball sampling, via a web survey, based on a semi-structured questionnaire elaborated by the authors, shared on social media. Results: The children and adolescents were represented by 129 accompanying family members from the five largest regions of Brazil. Low education level, housewifery, and low family income were associated with exclusive care provided by the Unified Health System, while low family income was associated with the use of ocular prosthesis post retinoblastoma. Conclusion: The identified odds ratio indicated the importance of family members' sociodemographic aspects for the clinical, epidemiological and care outcomes of the children and adolescents treated. Public healthcare services were the most used for oncology care, which endorses the relevance of the Unified Health System for children, adolescents, and their family members who have been impacted by retinoblastoma in the country (AU)

Introdução: O retinoblastoma impacta sobremaneira as crianças, adolescentes e familiares acometidos. Abordagens epidemiológicas sobre tal câncer no Brasil são escassas, lacuna esta que motivou este trabalho. Objetivos: Os objetivos desse estudo foram descrever as características sociodemográficas, clínicas, epidemiológicas e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil e analisar se existe associação entre tais características. Métodos: Tratou-se de um estudo transversal, descritivo-analítico, realizado com acompanhantes familiares de crianças e adolescentes atendidos por retinoblastoma no Brasil, amostrados por snowball sampling, via web survey, a partir de um roteiro autoral semiestruturado, compartilhado em mídias sociais. Os dados foram analisados por meio de estatística descritiva e inferencial, com o auxílio do software Statistical Package for the Social Sciences. Resultados: As crianças e os adolescentes foram retratados por 129 acompanhantes familiares das cinco grandes regiões brasileiras. A escolaridade baixa, a ocupação do lar e a baixa renda familiar dos respondentes associaram-se ao atendimento exclusivo pelo Sistema Único de Saúde, sendo que a baixa renda familiar também associou-se ao uso de prótese ocular pós retinoblastoma. Conclusões: As razões de chances identificadas sinalizaram para a importância dos aspectos sociodemográficos dos familiares para os desfechos clínicos-epidemiológicos-assistenciais das crianças e dos adolescentes atendidos. Os serviços públicos foram os mais utilizados para a assistência oncológica, o que endossa a relevância do Sistema Único de Saúde para as crianças, adolescentes e familiares impactados pelo retinoblastoma no país (AU)

Simultaneous occurrence of inflammatory bowel disease and trichomonosis in a Maine coon cat.

A 2-year-old, 4.2 kg, spayed female, Maine coon cat was referred to the veterinary hospital for evaluation of hyporexia, slow growth, and chronic, intermittent, mucoid, bloody, voluminous, and fetid diarrhea. The diarrhea had been observed since the cat was acquired from a cattery at 4 months of age; with acute worsening in the 5 d before presentation. Abdominal palpation revealed moderate pain. Ultrasonographic examination showed thickening of the jejunal wall and ileal loops, increased echogenicity of the jejunal mucosa, and enlargement of the jejunal and ileocolic lymph nodes. Histopathology of full-thickness intestinal biopsies showed moderate, diffuse, lymphoplasmacytic, erosive enteritis with hemorrhage and edema. Diffuse, lymphoplasmacytic, erosive colitis with mild, interstitial fibrosis and hemorrhage was also noted. The ileocecal lymph node biopsy showed eosinophilic lymphadenitis. Based on the immunohistochemical evaluation of intestinal samples with CD3 and CD79a antibodies, a diagnosis of lymphoma was ruled out. Fecal polymerase chain reaction testing was positive for Tritrichomonas foetus. Based on these results, inflammatory bowel disease and trichomonosis were diagnosed. Treatment for the cat included a hypoallergenic diet and an oral omega-3 fatty acid supplement, in conjunction with prednisolone, to manage the inflammatory bowel disease. Ronidazole was administered to target the Tritrichomonas foetus. The cat was clinically normal during a follow-up examination after 6 months of treatment.

Apparition simultanée d'une maladie inflammatoire de l'intestin et d'une trichomonose chez un chat Maine coon. Une chatte Maine coon de 2 ans, pesant 4,2 kg, stérilisée, a été référée à l'hôpital vétérinaire pour une évaluation d'hyporexie, de croissance lente et de diarrhée chronique, intermittente, mucoïde, sanglante, volumineuse et fétide. La diarrhée avait été observée depuis que le chat avait été acquis en chatterie à l'âge de 4 mois; avec une aggravation aiguë dans les 5 jours avant la présentation. La palpation abdominale a révélé une douleur modérée. L'examen échographique a montré un épaississement de la paroi jéjunale et des anses iléales, une augmentation de l'échogénicité de la muqueuse jéjunale et une hypertrophie des ganglions lymphatiques jéjunaux et iléocoliques. L'histopathologie des biopsies intestinales de pleine épaisseur a montré une entérite modérée, diffuse, lymphoplasmocytaire, érosive avec hémorragie et oedème. Une colite érosive diffuse, lymphoplasmocytaire avec fibrose interstitielle légère et hémorragie a également été notée. La biopsie ganglionnaire iléo-caecale montrait une lymphadénite à éosinophiles. Sur la base de l'évaluation immunohistochimique d'échantillons intestinaux avec des anticorps CD3 et CD79a, un diagnostic de lymphome a été écarté. Le test de réaction en chaîne par la polymérase sur les matières fécales était positif pour Tritrichomonas foetus. Sur la base de ces résultats, une maladie inflammatoire de l'intestin et une trichomonose ont été diagnostiquées. Le traitement du chat comprenait un régime hypoallergénique et un supplément oral d'acides gras oméga-3, en association avec de la prednisolone, pour gérer la maladie inflammatoire de l'intestin. Le ronidazole a été administré pour cibler Tritrichomonas foetus. Le chat était cliniquement normal lors d'un examen de suivi après 6 mois de traitement.(Traduit par Dr Serge Messier).

Aging-related episodic-like memory decline in dogs.

Episodic memory, in humans, is the memory most affected by age-related deterioration or the constitution of neurodegenerative pathologies, such as Alzheimer's disease. However, it is unknown whether this relationship is also present in nonhuman animals. Since studies in birds, rats, primates, and dogs have been shown to have episodic-like memory, more studies aiming to improve the present understanding of this relationship in nonhuman animals are important to aid the development of new translational models for neurodegenerative disorders. Knowing that dogs (Canis familiaris) represent a promising experimental model for neurodegenerative disorders, a memory retrieval test was conducted with 90 clinically healthy domestic dogs of different ages, both sexes, and distinct breeds, for the purpose of evaluating episodic-like memory. The present study adapted a test that corroborates episodic memory requirements through incidental codification of experienced events. We performed a test with two exposure phases, with different characteristics between them, so that in the third phase it was necessary to integrate previous experiences in order to achieve success in the test. In our study, it was possible to verify the decline of episodic memory in elderly dogs, even clinically healthy, regardless of the dogs' sex and size. This episodic-like memory decline observed in elderly dogs may be related to the physiological process of aging or preclinical pathological manifestation of cognitive impairment, similar as reported in humans. More studies should be carried out evaluating episodic-like memory in dogs with suspected of canine cognitive dysfunction syndrome in order to better understand the physiological and pathological behavior of this type of memory in canine species.

Sociodemographic, clinical, epidemiological and care aspects of children and adolescents treated for retinoblastoma in Brazil: a cross-sectional study / Aspectos sociodemográficos, clínicos, epidemiológicos e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil: estudo transversal

ABSTRACT: Introduction: Retinoblastoma greatly impacts the affected children and adolescents and their families. Epidemiological approaches to this form of cancer in Brazil are scarce, and this gap motivated this study. Objectives:This study aimed to describe the sociodemographic, clinical, epidemiological, and care characteristics of children and adolescents treated for retinoblastoma in Brazil and analyze whether there is any association between them. Methods: It is a cross-sectional, descriptive-analytical study, carried out with accompanying family members of children and adolescents treated for retinoblastoma in Brazil, sampled by snowball sampling, via a web survey, based on a semi-structured questionnaire elaborated by the authors, shared on social media. Results: The children and adolescents were represented by 129 accompanying family members from the five largest regions of Brazil. Low education level, housewifery, and low family income were associated with exclusive care provided by the Unified Health System, while low family income was associated with the use of ocular prosthesis post retinoblastoma. Conclusion: The identified odds ratio indicated the importance of family members' sociodemographic aspects for the clinical, epidemiological and care outcomes of the children and adolescents treated. Public healthcare services were the most used for oncology care, which endorses the relevance of the Unified Health System for children, adolescents, and their family members who have been impacted by retinoblastoma in the country.

RESUMO: Introdução: O retinoblastoma impacta sobremaneira as crianças, adolescentes e familiares acometidos. Abordagens epidemiológicas sobre tal câncer no Brasil são escassas, lacuna esta que motivou este trabalho. Objetivos: Os objetivos desse estudo foram descrever as características sociodemográficas, clínicas, epidemiológicas e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil e analisar se existe associação entre tais características. Métodos: Tratou-se de um estudo transversal, descritivo-analítico, realizado com acompanhantes familiares de crianças e adolescentes atendidos por retinoblastoma no Brasil, amostrados por snowball sampling, via web survey, a partir de um roteiro autoral semiestruturado, compartilhado em mídias sociais. Os dados foram analisados por meio de estatística descritiva e inferencial, com o auxílio do software Statistical Package for the Social Sciences. Resultados: As crianças e os adolescentes foram retratados por 129 acompanhantes familiares das cinco grandes regiões brasileiras. A escolaridade baixa, a ocupação do lar e a baixa renda familiar dos respondentes associaram-se ao atendimento exclusivo pelo Sistema Único de Saúde, sendo que a baixa renda familiar também associou-se ao uso de prótese ocular pós retinoblastoma. Conclusões: As razões de chances identificadas sinalizaram para a importância dos aspectos sociodemográficos dos familiares para os desfechos clínicos-epidemiológicos-assistenciais das crianças e dos adolescentes atendidos. Os serviços públicos foram os mais utilizados para a assistência oncológica, o que endossa a relevância do Sistema Único de Saúde para as crianças, adolescentes e familiares impactados pelo retinoblastoma no país.

Microalgae cultivation in wastewater from agricultural industries to benefit next generation of bioremediation: a bibliometric analysis.

The aim of this study was to provide a bibliometric analysis and mapping of existing scientific papers, focusing on microalgae cultivation coupled with biomass production and bioremediation of wastewater from agricultural industries, including cassava, dairy, and coffee. Using the Web of Science (WoS) database for the period 1996-2021, a search was performed using a keyword strategy, aiming at segregating the papers in groups. For the first search step, the keywords "wastewater treatment", AND "microalgae", AND "cassava" OR "dairy" OR "coffee" were used, resulting in 59 papers. For the second step, the keywords "wastewater treatment" AND "biomass productivity" AND "microalgae" AND "economic viability" OR "environmental impacts" were used, which resulted in 34 articles. In these papers, keywords such as "carbon dioxide biofixation" and "removal of nutrients by the production of biomass by microalgae" followed by "environmental and economic impacts" were highlighted. Some of these papers presented an analysis of the economic feasibility of the process, which reveal the state-of-the-art setup required to make the cultivation of microalgae economically viable. Researches focusing on the efficiency of microalgae biomass harvesting are needed to improve the integration of microalgae production in industrial eco-parks using wastewater to achieve the global goal of bioremediation and clean alternatives for renewable energy generation.

Three Hundred is a teaching and learning method that seeks to awaken the eyes of the student towards the colleague with learning difficulties, promoting collaboration between students. The objective of this work is to report the application of the Three Hundred method in the discipline of physiology and to compare the performance of students before and after the method. Thirteen students participated in the study and were divided, by lot, into 3 groups. The groups were composed of one student who had above-average grades in a previous assessment and 3 or 4 students who had below-average grades. These groups met in extra classes twice a week for three weeks. In these meetings, students with higher averages helped others in activities that were directed by the discipline's teacher. At the end of the meetings, a new evaluation was carried out. The data were tabulated and analyzed using SPSS version 16. It was found that all students were able to increase their averages compared to the grades of the first assessment. Thus, it is concluded that the method can have benefits in the performance of students, as well as stimulate collaborative learning (AU).

The biosonar of the boto: evidence of differences among species of river dolphins (Inia spp.) from the Amazon.

Echolocation clicks can reflect the anatomy of the vocalizing animal, enabling the distinction of species. River dolphins from the family Iniidae are formally represented by one species and two subspecies (Inia geoffrensis geoffrensis and I. g. humboldtiana). Additionally, two other species have been proposed (I. boliviensis and I. araguaiaensis) regarding its level of restricted distribution and morph-genetics differences. For the Committee on Taxonomy of the Society for Marine Mammalogy, the specific status of the proposed species relies on further knowledge on morphology, ecology, and genetics. Given that species-specific status is required for conservation efforts, we described and compared the echolocation clicks of Inia spp., searching for specific differences on their vocalizations. The sounds were captured with a Cetacean Research ™ C54XRS (+3/-20 dB, -185 dB re: 1V/µPa) in Guaviare River (Orinoco basin), Madeira River (Madeira basin), Xingu River (Amazon Basin), and Araguaia River (Tocantins-Araguaia basin). We found significant differences in all analyzed parameters (peak frequency, 3 dB bandwidth, 10 dB bandwidth and inter-click interval) for all species and subspecies. Differences in acoustical parameters of clicks are mainly related to the animal's internal morphology, thus this study may potentially support with information for the species-level classification mostly of I. araguaiaensis (the Araguaian boto). Classifying the Araguaian boto separately from I. geoffrensis has important implications for the species in terms of conservation status, since it is restricted to a highly impacted river system.
