Incidência de parasitas intestinais em crianças e manipuladoras de alimentos em uma creche no município de Codó-Maranhão / Incidence of intestinal parasites in children and food handlers in a day care center in Codó-Maranhão
Introdução: Em todo o mundo, milhares de pessoas sofrem com infecções intestinais causadas por parasitos e a maior incidência ocorre em crianças em idade escolar devido ao seu sistema imunológico imaturo, maior facilidade de transmissão e maus hábitos de higiene pessoal. Objetivo: Examinar as ocorrências de parasitoses intestinais, por meio de exame coproparasitológico, em crianças e manipuladoras de alimentos numa creche em uma cidade do Maranhão. Métodos: Distribuiu-se coletores fecais para os pais das crianças e manipuladoras de alimentos participantes. Esses efetuaram as coletas dos materiais fecais para posterior realização de exame coproparasitológico. Aplicou-se também um questionário com os pais das crianças da creche. Resultados: Dentre os participantes da pesquisa, 60% estavam parasitados com pelo menos uma espécie de enteroparasita. Os parasitas encontrados foram Endolimax nana, Ascaris lumbricoides e Giardia lamblia e, entre as variáveis abordadas no questionário, houve relação significativa entre o resultado do exame coproparasitológico e o destino da água. Conclusão: Os resultados demonstram a necessidade de implementação de medidas de saneamento básico aplicadas à comunidade estudada e programas contínuos nas creches, visando a educação sanitária
Eruca sativa plants modulate growth and gas exchange when cultivated under salinity stress after leaching fractions
The physiology of rocket plants at different salinity levels through irrigation water and leaching fractions was assessed. Four salinity levels of irrigation water: 0.10, 1.60, 3.10 and 4.60 dS m-1 and three leaching fractions: 0, 10 and 20% were applied. The physiological variables analyzed were photosynthetic rate, stomatal conductance, transpiration rate and photosynthetic pigment contents. The growth and biomass production were analyzed by: plant height, number of leaves, leaf area and partitioned and total plant fresh and dry mass, and root to aerial part ratio. The leaching fraction of 10% combined with irrigation with water salinity levels ranging from 0.10 to 0.88 dS m-1 resulted in greater plant height, leaf area and root, shoot and total dry mass. The leaching fraction of 20% with irrigation water with salinity levels from 0.10 to 2.7 dS m-1 generates higher leaf number, shoot fresh mass, root-to-shoot ratio, stomatal conductance, and photosynthetic rate. Irrigation water with a salinity level of 0.10 dS m-1 provides a higher transpiration rate for rocket plants. Irrigation water with a salinity level of 4.6 dS m-1 generates higher chlorophyll a, b and total (a + b) and carotenoid contents in rocket plants
A MÚSICA COMO INTERVENÇÃO E CUIDADOS EM SAÚDE:: REVISÃO INTEGRATIVA
Este estudo objetivou sintetizar os resultados encontrados em estudos científicos sobre a musicoterapia como intervenção de cuidados em saúde, assim como descrever as áreas de maior utilização dessa terapia. Revisão integrativa utilizando artigos indexados na base de dados da Literatura Latino-Americana em Ciências da Saúde (LILACS), no período de Janeiro de 2006 a Dezembro de 2011. Para realização da busca, utilizou-se a combinação dos descritores música, enfermagem, atenção integral à saúde. Foram selecionados 34 artigos, sendo que destes, somente oito fizeram parte do estudo por atenderem os critérios estabelecidos. Em relação ao método da pesquisa, 75% eram de natureza qualitativa e 25% bibliográfica. Os resultados ressaltam a importância da utilização da música como terapia complementar, como intervenção voltada ao profissional e estudante de enfermagem e como recurso em tratamentos e intervenções hospitalares. Além disso, foi observada a necessidade de associar a música ao cuidado de enfermagem levando em conta o relacionamento interpessoal, a expressividade emocional e afetiva e os aspectos histórico-culturais dos indivíduos, refletindo assim diretamente na qualidade do atendimento. Esta prática pode ser utilizada como intervenção no espaço hospitalar, pois é um recurso de baixo custo, não farmacológico e que ajuda a promover a melhora no quadro dos pacientes
Diagnosis, Prognosis and Treatment of Canine Cutaneous and Subcutaneous Mast Cell Tumors
Mast cell tumors (MCTs) are hematopoietic neoplasms composed of mast cells. It is highly common in dogs and is extremely important in the veterinary oncology field. It represents the third most common tumor subtype, and is the most common malignant skin tumor in dogs, corresponding to 11% of skin cancer cases. The objective of this critical review was to present the report of the 2nd Consensus meeting on the Diagnosis, Prognosis, and Treatment of Canine Cutaneous and Subcutaneous Mast Cell Tumors, which was organized by the Brazilian Association of Veterinary Oncology (ABROVET) in August 2021. The most recent information on cutaneous and subcutaneous mast cell tumors in dogs is presented and discussed
Recruitment, training and supervision of nurses and nurse assistants for a task-shifting depression intervention in two RCTs in Brazil and Peru.
BACKGROUND: Task-shifting and technology in psychological interventions are two solutions to increasing access to mental health intervention and overcoming the treatment gap in low and middle-income countries. The CONEMO intervention combines a smartphone app with support from non-specialized professionals, aiming to treat depression in patients with diabetes and/or hypertension. The aim of this paper is to describe the process of recruitment, training and supervision of the non-specialized professionals who participated in the CONEMO task-shifting intervention in Brazil and Peru. METHODS: We described and analyzed data related to the recruitment, training and supervision of 62 nurse assistants from the health system in Sao Paulo, Brazil, and three hired nurses in Lima, Peru. The data were collected from information provided by nurses and nurse assistants, supervisor records from supervision meetings and the CONEMO platform database. RESULTS: We found that task-shifting was feasible using existing resources in Sao Paulo and additional human resources in Lima. Training and supervision were found to be crucial and well received by the staff; however, time was a limitation when using existing human resources. Ensuring technological competence prior to the start of the intervention was essential. Group supervision meetings allowed non-specialized professionals to learn from each other's experiences. CONCLUSION: Carefully considering recruitment, training and supervision of non-specialized professionals is important for effective task-shifting when delivering an mHealth intervention for depression. Opportunities and challenges of working in different health systems are described, which should be considered in future implementation, either for research or real settings.

A Mobile Health Intervention for Patients With Depressive Symptoms: Protocol for an Economic Evaluation Alongside Two Randomized Trials in Brazil and Peru
BACKGROUND: Mobile health interventions provide significant strategies for improving access to health services, offering a potential solution to reduce the mental health treatment gap. Economic evaluation of this intervention is needed to help inform local mental health policy and program development. OBJECTIVE: This paper presents the protocol for an economic evaluation conducted alongside 2 randomized controlled trials (RCTs) to evaluate the cost-effectiveness of a psychological intervention delivered through a technological platform (CONEMO) to treat depressive symptoms in people with diabetes, hypertension, or both. METHODS: The economic evaluation uses a within-trial analysis to evaluate the incremental costs and health outcomes of CONEMO plus enhanced usual care in comparison with enhanced usual care from public health care system and societal perspectives. Participants are patients of the public health care services for hypertension, diabetes, or both conditions in São Paulo, Brazil (n=880) and Lima, Peru (n=432). Clinical effectiveness will be measured by reduction in depressive symptoms and gains in health-related quality of life. We will conduct cost-effectiveness and cost-utility analyses, providing estimates of the cost per at least 50% reduction in 9-item Patient Health Questionnaire scores, and cost per quality-adjusted life year gained. The measurement of clinical effectiveness and resource use will take place over baseline, 3-month follow-up, and 6-month follow-up in the intervention and control groups. We will use a mixed costing methodology (ie, a combination of top-down and bottom-up approaches) considering 4 cost categories: intervention (CONEMO related) costs, health care costs, patient and family costs, and productivity costs. We will collect unit costs from the RCTs and national administrative databases. The multinational economic evaluations will be fully split analyses with a multicountry costing approach. We will calculate incremental cost-effectiveness ratios and present 95% CIs from nonparametric bootstrapping (1000 replicates). We will perform deterministic and probabilistic sensitivity analyses. Finally, we will present cost-effectiveness acceptability curves to compare a range of possible cost-effectiveness thresholds. RESULTS: The economic evaluation project had its project charter in June 2018 and is expected to be completed in September 2021. The final results will be available in the second half of 2021. CONCLUSIONS: We expect to assess whether CONEMO plus enhanced usual care is a cost-effective strategy to improve depressive symptoms in this population compared with enhanced usual care. This study will contribute to the evidence base for health managers and policy makers in allocating additional resources for mental health initiatives. It also will provide a basis for further research on how this emerging technology and enhanced usual care can improve mental health and well-being in low- and middle-income countries.

Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
Studies of the mass composition of cosmic rays and proton-proton interaction cross-sections at ultra-high energies with the Pierre Auger Observatory
In this work, we present an estimate of the cosmic-ray mass composition from the distributions of the depth of the shower maximum (Xmax) measured by the fluorescence detector of the Pierre Auger Observatory. We discuss the sensitivity of the mass composition measurements to the uncertainties in the properties of the hadronic interactions, particularly in the predictions of the particle interaction cross-sections. For this purpose, we adjust the fractions of cosmic-ray mass groups to fit the data with Xmax distributions from air shower simulations. We modify the proton-proton cross-sections at ultra-high energies, and the corresponding air shower simulations with rescaled nucleus-air cross-sections are obtained via Glauber theory. We compare the energy-dependent composition of ultra-high-energy cosmic rays obtained for the different extrapolations of the proton-proton cross-sections from low-energy accelerator data
