    OBJETIVO: Caracterizar o perfil de utilização de medicamentos pelos usuários da Atenção Primária do Sistema Único de Saúde no Brasil. MÉTODOS: Estudo transversal, exploratório, de natureza descritiva, integrante da Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015. Foram realizadas entrevistas com usuários presentes nos serviços por meio de questionários semiestruturados. Foram avaliadas as variáveis sociodemográficas, clínicas e relacionadas ao uso de medicamentos e verificado o uso de medicamentos nos 30 dias anteriores à entrevista. A população foi estratificada em três faixas etárias: 18 a 44, 45 a 64 e 65 anos ou mais. As diferenças entre as faixas etárias foram verificadas por meio do teste t de Student para variáveis contínuas e teste qui-quadrado para categóricas. Utilizou-se o plano de análises de amostras complexas. Os medicamentos foram classificados conforme Anatomical Therapeutical Chemical Classification System. RESULTADOS: De 8.803 usuários entrevistados, 6.511 (76,2%) relataram uso de medicamentos nos 30 dias anteriores à entrevista. Em média, cada usuário utilizou 2,32 medicamentos, sem diferença entre os sexos. Dentre os usuários de medicamentos, 18,2% tinham 65 anos de idade ou mais. Em comparação com as demais faixas etárias os idosos apresentaram mais comorbidades, usaram mais medicamentos e autorrelataram pior condição de saúde; eram menos escolarizados, relataram pior situação econômica e viviam sozinhos. Os medicamentos mais utilizados foram “outros analgésicos e antipiréticos” (3º nível ATC) e losartana (5º nível ATC). CONCLUSÕES: A maioria dos usuários de medicamentos possuía baixa escolaridade e comorbidades. Os medicamentos mais utilizados foram os anti-hipertensivos. A automedicação foi maior entre os jovens. A maioria dos usuários relatou utilização de medicamentos genéricos. O número médio de medicamentos e a prevalência de uso aumentaram com a idade. Devido às características observadas e as dificuldades no uso de medicamentos, os idosos estão em situação de maior vulnerabilidadeOBJECTIVE: To characterize the use of medicines by patients of the primary health care of the Brazilian Unified Health System (SUS). METHODS: This is a cross-sectional, exploratory, and descriptive study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). Interviews were carried out with patients present in the services by semi-structured questionnaires. Sociodemographic, clinical, and use of medicines variables were assessed and the use of medicines in the 30 days prior to the interview was also verified. The population was stratified into three age groups: 18 to 44, 45 to 64, and 65 years or more. The differences between the age groups were verified using the Student’s t-test for continuous variables and chi-square test for the categorical ones. The complex samples analysis plan was employed. The medicines were classified according to the Anatomical Therapeutic Chemical Classification System. RESULTS: Of the 8,803 patients interviewed, 6,511 (76.2%) reported to have used medicines in the 30 days prior to the interview. On average, each patient used 2.32 medicines, without difference between the sexes. Among medicine users, 18.2% were aged 65 years or more. Compared to the other age groups, older adults presented more comorbidities, used more medicines, and self-reported worse health conditions. They were also less educated, reported worse economic situation, and lived alone. The medicines that were mostly used were “other analgesics and antipyretics” (3rd ATC level) and Losartan (5th ATC level). CONCLUSIONS: Most medicine users had lower education level and presented comorbidities. The most used medicines were the antihypertensive ones. Self-medication was higher among young people. Most patients reported to use generic medicines. The average number of medicines and the prevalence of use increased with age. Due to the characteristics observed and the difficulties in the use of medicines, older adults are in a situation of greater vulnerabilit

    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

    ABSTRACT. Paula M.A.M., Oliveira F.C.R., Melo Jr O.A. & Frazão-Teixeira E. [Prevalence of Babesia spp. and Anaplasma marginale in cattle in the municipality of Palma, MG.] Prevalência de Babesia spp. e Anaplasma marginale em bovinos no município de Palma, MG. Revista Brasileira de Medicina Veterinária, 37(4): 359-365, 2015. Laboratório de Biologia Estrutural, Instituto Oswaldo Cruz/ Fiocruz, Avenida Brasil, 4365, Manguinhos, Rio de Janeiro, RJ 21040-361, Brasil. E-mail: [email protected] We verified the prevalence of hemoparasites in 40 cattle with ages varying from one month to 12 years old, in two farms of the Municipality of Palma, Minas Gerais state, Brazil. Two blood smear samples were collected from each animal: one from the tail tip and another from the ear tip. The smears were fixed, stained and observed under 100X lighted microscope magnifying glass. Twenty- -seven out of 40 animals studied (67.5%) had at least one species of hemoparasite. Among these, 21 (52.5%) were infected with Babesia spp., 10 (25%) with Anaplasma marginale and four (10%) parasitized with both hemoparasites. The studied region is potentially enzootic for the detected parasites and there is high risk for clinical cases of tick-borne disease. Both anatomic points, tail and ear tips, are good spots for blood collection and smear confection for hemoparasite investigation

    O mogno-brasileiro possui alto valor madeireiro, mas seu cultivo comercial é inviabilizado pelo ataque da broca Hypsipyla grandella. Objetivou-se avaliar o efeito de doses de cálcio e boro nas variáveis de crescimento do mogno e na resistência ao ataque da broca H. grandella . O delineamento utilizado foi o fatorial 4² em blocos ao acaso com quatro doses de cálcio (0, 100, 200 e 400 mg L-1) e quatro de boro (0; 0,5; 2; e 4 mg L-1) e três repetições com três plantas por repetição. Avaliaram-se: altura, diâmetro, massa seca aérea e de raiz, relação parte aérea:raiz, taxa de infestação e comprimento da galeria construída pela broca. Os dados foram submetidos ao teste de Tukey a 5% e à análise de correlação e regressão. Não houve interação estatística entre os nutrientes, nem significância de altura e diâmetro do coleto. A massa de raízes e da parte aérea apresentou os maiores resultados na omissão dos elementos, verificando as menores relações parte aérea:raiz nas doses de 100 mg L-1 em função do cálcio e 0,5 mg L-1 em função do boro. A dose de 100 mg Ca L-1 proporcionou a menor taxa de infestação de H. grandella. Para a resistência do mogno ao desenvolvimento da galeria, tanto o cálcio quanto o boro apresentaram significância, sendo os menores comprimentos verificados nas doses de 100 mg L-1 Ca e 0,5 mg L-1 B, respectivamente. Esses nutrientes influenciam a resistência do mogno ao ataque da broca e evidenciam a necessidade de estudos em condições de campo

    Verificaram-se os efeitos da variação mensal, propriedade e estado fisiológico sobre o Famacha©, volume globular, contagem de ovos por grama de fezes, condição corporal e peso vivo em ovelhas Santa Inês do norte do estado do Rio de Janeiro. O trabalho foi realizado em três propriedades, de janeiro a dezembro de 2006. A cada 14 dias, 20 ovelhas de cada propriedade foram pesadas, avaliadas quanto a condição corporal, Famacha©, e foram coletadas amostras de fezes para realização de contagem de ovos por grama de fezes (OPG) e coprocultura, e amostras de sangue para avaliar o volume globular. Haemonchus foi o gênero predominante, seguido de Trichostrongylus. Observaram-se diferenças (P<0,01) para Famacha©, volume globular, OPG, condi ção corporal e peso vivo devido aos efeitos da variação mensal, propriedade e estado fisiológico. Conclui-se que as variações climáticas, com interferência no desenvolvimento larval e na qualidade e quantidade de forragem e, principalmente, o estado fisiológico das ovelhas ocasionam variações mensais na infecção por nematódeos gastrintestinais
