Abstract This study aimed to compare the lists of medicines offered by the England (National Health Service -NHS) and Brazilian (Sistema Único de Saúde - SUS) health systems. The analysis was performed using the chemical subgroup (4th level) of the Anatomical Therapeutic Chemical classification (ATC), focusing on the main causes of disability-adjusted life years (DALYs) found in the 2019 Global Disease Burden study for both countries: cardiovascular, musculoskeletal and mental disorders. The comparison between the Drug Tariff of March 2020 (England) and the Relação Nacional de Medicamentos Essenciais (Rename) 2020 (Brazil) showed that the former contains 3,620 pharmaceutical presentations and Rename, 921, with 3,158 and 796 being monodrugs, respectively. Drug Tariff has 3.9 times more pharmaceutical presentations than Rename and 2 times more active substances in monodrugs than Rename. Rename and Drug Tariff have 281 active chemicals in common, considering the 5th level of the ATC. The list of medicines financed by the NHS is broader than that of Brazil, both for diseases in general and for diseases prevalent in both countries, which may constitute a possibility of improvement for Rename, keeping the need for more studies in-depth on the topic.

Resumo Objetivou-se comparar as listas de medicamentos oferecidos pelos sistemas públicos de saúde inglês e brasileiro, averiguando a amplitude das possibilidades terapêuticas em ambos os países. Na análise utilizou-se o subgrupo químico (4º nível) da classificação anatômica, terapêutica e química (Anatomic Therapeutic Chemical classification – ATC), com foco nas três principais causas de anos de vida perdidos ajustados pela incapacidade (Disability-Adjusted Life Years - DALYs) encontrados no estudo de Carga Global de Doenças de 2019, comuns a ambos os países: doenças cardiovasculares, músculo-esqueléticas e mentais. Da comparação entre a Drug Tariff de março de 2020 (Inglaterra) e a Relação Nacional de Medicamentos Essenciais (Rename) 2020 (Brasil) emergiu que a Drug Tariff contém 3.620 apresentações farmacêuticas e a Rename, 921, sendo que 3.158 e 796 são monofármacos, respectivamente; um número 3,9 vezes maior de apresentações farmacêuticas que a Rename e duas vezes maior de substâncias ativas. A Rename e a Drug Tariff possuem 281 substâncias químicas ativas em comum, considerando o 5º nível da ATC. A lista de medicamentos financiados pelo NHS apresenta-se mais ampla que a do Brasil, tanto para doenças em geral, quanto para as doenças prevalentes nos dois países, podendo-se constituir uma possibilidade de aprimoramento para a Rename.

Resumen En la región semiárida de Paraíba, el caupí es el principal producto de la agricultura familiar. El cultivo tiene baja productividad debido a lluvias irregulares y condiciones climá ticas desfavorables. Además, la productividad también se ve afectada por el uso deficiente de las tecnologías de producción. Con el objetivo de superar estas limitaciones y aumentar la eficiencia de la selección de cultivares superiores, se llevó a cabo un extenso estudio utili zando modelos biométricos en caupí. Este primer trabajo tuvo los siguientes objetivos: i. Cuantificar los efectos directos e indirectos de los componentes primarios y secundarios en la producción de granos; ii. Identificar variables con mayor potencial para la selección de cultivares de caupí en la región semiárida de Paraíba y iii. Determinar las estrategias de selección más adecuadas para el conjunto de variables evaluadas. El experimento se llevó a cabo en un campo experimental en el Centro de Ciencia y Tecnología Agroalimentaria de la Universidad Federal de Campina Grande. Se evaluó la influencia de 6 componentes primarios y 6 componentes secundarios de la producción sobre la variable rendimiento de grano. Los datos se sometieron a ANAVA y se estimaron parámetros genéticos. También se realizaron correlaciones y análisis de ruta. Se identificaron variables con mayor potencial para la selección de cultivares superiores de caupí en la región semiárida de Paraíba. Se encontró que la variable rendimiento de vaina es la más prometedora para la selección de cultivares con mayor rendimiento de grano debido a la magnitud de los efectos fenotípico y genotípico. La selección directa y la selección simultánea son las estrategias más adecuadas para el conjunto de variables evaluadas. Sin embargo, para maximizar las ganancias gené ticas, se continuó el estudio a través de índices de selección.

Abstract In the semi-arid region of Paraíba, cowpea has low productivity due to irregular rainfall and poor use of production technologies. An extensive study aimed at selecting more productive cultivars was conducted using biometric models. This first work had the following objectives: i. Quantify direct and indirect effects of primary and secondary compo nents on grain production; ii. Identify variables with greater potential for cultivar selection in the semiarid region of Paraíba and iii. Determine the most appropriate selection strat egies for the evaluated variables. The experiment was conducted in an experimental field. The influence of 6 primary and 6 secondary production components was evaluated on grain yield. Data were subjected to ANOVA. Genetic parameters, correlations and path analysis were estimated. Given the strong direct phenotypic and genotypic effects, pod yield results the most promising variable for higher grain yield selection. Direct and simultaneous selec tions are the most suitable strategies for the set of evaluated variables. However, further studies on selection indices are necessary to maximize genetic gains.

Resumen En la región semiárida de Paraíba, el caupí (Vigna unguiculata (L.) Walp) es el prin cipal producto de la agricultura familiar. El cultivo tiene baja productividad debido a lluvias irregulares y al uso de cultivares de baja productividad. Con el objetivo de superar estas limitaciones y aumentar la eficiencia de la selección de cultivares superiores, se llevó a cabo un extenso estudio utilizando modelos biométricos en caupí, con los siguientes obje tivos: i. Estimar las ganancias genéticas de los componentes de la producción; ii. Identi ficar el modelo de índice de selección que proporciona las mayores ganancias mediante la selección simultánea de un conjunto de variables y iii. Seleccionar cultivares con mayor productividad. El experimento se llevó a cabo en el campo experimental del Centro de Ciencia y Tecnología Agroalimentaria de la Universidad Federal de Campina Grande. Se evaluaron 13 variables relacionadas con la productividad. Los datos se sometieron a ANOVA y las medias se agruparon según la prueba de Scott y Knott p≤ 0,05. También se estimó el coeficiente de heredabilidad de cada variable. Las ganancias genéticas se estimaron utili zando las siguientes metodologías: respuesta correlacionada, índice de selección clásico, suma de rango e índice basado en las ganancias deseadas. Se encontró que la selección directa del componente de rendimiento de la vaina secundaria proporciona ganancias genéticas significativas en rendimiento de grano. Entre las metodologías utilizadas, el índice de selección clásico proporcionó una mayor distribución de las ganancias genéticas para rendimiento de grano y para los componentes primarios de producción. Estos resultados permiten concluir que los cultivares Costela de vaca, BRS Marataoã y Paulistinha pueden seleccionarse para cultivo y explotación en la región semiárida de Paraíba.

Abstract Low cowpea productivity (Vigna unguiculata (L.) Walp) in the semi-arid region of Paraíba is due, among other factors, to poor-quality cultivars. This research tested biometric models intending to increase productivity of superior cultivars with the following objectives: i. Estimate genetic gains in production components; ii. Identify the selection index model providing the greatest gains through simultaneously selecting a set of variables, and iii. Select cultivars with higher productivity. The experiment was carried out in the experimental field of the Agrifood Science and Technology Center of the Federal University of Campina Grande. Eight cultivars and 13 variables were evaluated. Data were subjected to ANOVA and means were grouped using the Scott and Knott test. Genetic gains were estimated by correlated response, classic selection index, rank sum and index based on desired gains. Direct selection of the secondary pod yield component provides significant genetic gains in main grain yield. Among the methodologies used, the classic selection index provided greater distribution of genetic gains for main grain yield and primary production components. These results allow concluding that Costela de vaca, BRS Marataoã and Paulistinha cultivars should be selected for cultivation and commercial exploitation in the semiarid region of Paraíba.

Resumo Coxiella burnetii é um agente zoonótico transmitido principalmente por pequenos ruminantes. No Brasil, a doença foi classificada como de notificação compulsória desde 2013, quando casos humanos foram relatados. O objetivo deste estudo foi identificar os fatores de risco associados à presença de anticorpos anti-Coxiella burnetii em caprinos e ovinos em uma região semiárida do Nordeste do Brasil. Este estudo envolveu um inquérito sorológico de 412 caprinos e 403 ovinos em fazendas do município de Petrolina, no estado de Pernambuco. Os soros foram examinados pela Reação de Imunofluorescência Indireta (RIFI) contra antígenos de C. burnetii . Informações sobre variáveis de manejo (variáveis independentes) que poderiam estar associadas à presença do microrganismo (variáveis dependentes) foram obtidas do proprietário de cada fazenda. Foi determinado que 2,2% (9/412) dos caprinos e 2,1% (9/403) dos ovinos tinham anticorpos reativos a C. burnetii. A presença de anticorpos anti-C. burnetii foram associados com a área seca do Sequeiro (região no norte do município de Petrolina) (P = 0,025), ovinos machos (P = 0,020) e criação intensiva de caprinos (P = 0,005). Este estudo, portanto, observou a presença de anticorpos anti-C. burnetii em pequenos ruminantes, confirmando pela primeira vez que este agente pode estar circulando em rebanhos caprinos no bioma Caatinga, semiárido do Brasil.

Abstract Coxiella burnetii is a zoonotic agent transmitted mainly by small ruminants. In Brazil the disease has been classified as a notifiable disease since 2013, when human cases were reported. This study aimed to identify risk factors associated with the presence of anti- Coxiella burnetii antibodies in goats and sheep in a semiarid region of Northeastern Brazil. Sera of 412 goats and 403 sheep from municipality of Petrolina, Pernambuco, were examined by the Indirect Fluorescent Antibody Test (IFAT) against antigens of C. burnetii. Information about management variables (independent variables) that could be associated with the presence of the microorganism (dependent variables) were obtained from the supervisor of each farm. It was determined that 2.2% (9/412) of the goats and 2.1% (9/403) of the sheep had antibodies reactive to C. burnetii. The presence of anti-C. burnetii antibodies was associated with the dry area of the Sequeiro (a region in the northern part of the municipality of Petrolina) (P = 0.025), male sheep (P = 0.020), and intensive goat breeding (P = 0.005). This study therefore showed the presence of anti-C. burnetii antibodies in goat and sheep, confirming for the first time that this agent is likely circulating among goat herds in the Caatinga Biome, semi-arid of Brazil.

Abstract: En | Text: En | PDF: En

Oral care is frequently suboptimal in children from developing countries, especially those suffering from severe systemic diseases. The aim of the present study was to analyze the oral epidemiological profile of 3-to-5-year-old children with congenital heart disease. Dental and medical records of children evaluated at the Dental Service of the National Institute of Cardiology, Rio de Janeiro, Brazil, were reviewed. Caries experience was reported using the dmft index. Negative behavior towards dental management was recorded. The sample consisted of 144 children aged 4.41 ± 0.95 years. The mean dmft value was 5.4 ± 4.9, and 80.5% had at least one caries lesion. Dmft index was greater in the presence of cyanotic cardiac disease and in children with negative behavior. An increase in the “missing” component of the dmft index was also found in children using medicine on a daily basis. A higher caries experience was associated with children whose fathers had only an elementary education. In conclusion, children with congenital heart disease had high levels of caries experience at a young age. Cyanosis, negative behavior, daily use of medicine, one-parent family and the educational level of fathers seem to influence caries experience in children with congenital cardiac disease.

O objetivo do presente trabalho foi avaliar criticamente o processo de adaptação transcultural dos principais instrumentos de qualidade de vida relacionados à saúde bucal. Foram realizadas buscas nas bases de dados bibliográficos LILACS e MEDLINE, com o intuito de encontrar estudos que se propuseram a adaptar instrumentos para mensuração de qualidade de vida relacionada à saúde bucal para culturas diferentes daquela em que o instrumento original foi desenvolvido. Vinte e nove artigos foram avaliados. Foi verificada grande disparidade nos métodos empregados para adaptar instrumentos de mensuração de qualidade de vida relacionada à saúde bucal, o que limita a futura utilização dos indicadores não adaptados corretamente, uma vez que eles podem não representar uma medida correta da saúde dessa população.

The aim of this study was to evaluate the cross-cultural adaptation of the main quality of life instruments related to oral health. Studies on cross-cultural adaptation of oral health-related quality of life measures were searched for in LILACS and MEDLINE. Twenty-nine articles were analyzed, identifying distinct methods for cross-cultural adaptation of oral health-related quality of life measures. Such differences could jeopardize the future use of these instruments, since the instruments may not adequately represent the health status of the respective target populations.

O objetivo do estudo foi investigar as características morfológicas do esmalte decíduo desmineralizado submetido à escovação com dentifrício fluoretado ou não fluoretado. Para isto, 32 blocos de esmalte foram separados em 4 grupos diferentes, contendo 8 elementos cada que foram imersos em saliva artificial por 15 dias: C = controle; E = atacado com gel de ácido fosfórico a 37% por 30 segundos; EB = atacado e escovado 3 vezes ao dia com dentifrício não fluoretado; EBF = atacado e escovado 3 vezes ao dia com dentifrício fluoretado. A escovação foi padronizada em 0,2 kgf e 15 movimentos de vai-e-vem foram executados em cada bloco. Após o período experimental, as amostras foram preparadas e examinadas no MEV. O grupo controle (C) apresentou lisura superficial e riscos causados pela escovação habitual; as amostras atacadas (E) apresentaram diferentes graus de desintegração superficial, porém o padrão de ataque ácido foi predominantemente a dissolução do tipo II. As superfícies escovadas apresentaram-se alisadas, com exposição das elevações correspondentes aos processos de Tomes e as depressões de esmalte interprismático. Partículas semelhantes a carbonato de cálcio foram encontradas nas partes mais protegidas das depressões. Não houve diferença quando os grupos foram escovados com dentifrício fluoretado (EBF) e dentifrício sem fluoreto (EB). Os resultados sugerem que a abrasão mecânica da escovação com dentifrício sobre o esmalte desmineralizado alisa a superfície rugosa causada pelo condicionamento ácido e que a presença do fluoreto não altera morfologicamente este padrão.

The aim of this study was to investigate, in vitro, the morphological characteristics of demineralized primary enamel subjected to brushing with a dentifrice with or without fluoride. In order to do so, 32 enamel blocks were divided in 4 different groups containing 8 blocks each. They were separately immersed in artificial saliva for 15 days. The experimental groups were: C - control; E - submitted to etching with 37% phosphoric acid gel (30 s); EB - submitted to etching and brushing 3 times a day with a non-fluoridated dentifrice; EBF = submitted to etching and brushing 3 times a day with a fluoridated dentifrice. The toothbrushing force was standardized at 0.2 kgf and 15 double strokes were performed on each block. After the experimental period, the samples were prepared and examined under SEM. The control group (C) showed a smooth surface, presenting scratches caused by habitual toothbrushing. The etched samples (E) exhibited different degrees of surface disintegration, but the pattern of acid etching was predominantly the type II dissolution. The brushed surfaces were smooth, with elevations which corresponded to the exposure of Tomes’ process pits and depressions which corresponded to interrod enamel. Particles resembling calcium carbonate were found in the most protected parts of the grooves. No morphological differences were observed between brushing with fluoridated (EBF) and non-fluoridated (EB) dentifrice. The results suggest that the mechanical abrasion caused by brushing demineralized enamel with dentifrice smoothes the rough etched surface, and the presence of fluoride does not cause morphological modifications in this pattern.
