Abstract The aim was to associate living, health and oral health conditions with the quality of life (QL) of children and adolescents (CA) with sickle cell disease (SCD). Of the 120 eligible users of a public hematological service, 106 CA with SCD from 6 to 18 years of age, and their caregivers, answered semi-structured questions about socio-demographic, health and oral health conditions. For QL, we used the validated instrument PedsQLSCD™. The oral clinical examination occurred according to the guidelines of WHO and SB Brazil 2010. The majority of CA were non-white people (88%), mean age of 10.4 (±2.9) years, family income of up to two monthly minimum wages, for 03 to 05 members, with diagnosis of sickle cell anemia by neonatal screening, hospitalizations were due allergic crises, polypharmacy and dental caries (51%) were present. “About the Impact of My Pain” was the best-fit model for the QLSCD (adjusted R²=56%; AIC=28.67; p=0.04). Dental caries in permanent dentition worsened the QLSCD (OR=0.53; IC95%=0.35-0.78; p<0.05) and was associated with the type of school, car ownership, number of family members, of complications and of the medications. To overcome this scenario, programmatic actions are required, and implementation of public policies specifically directed towards these groups.

Resumo Objetivou-se associar condições de vida, de saúde e de saúde bucal à qualidade de vida (QLV) de crianças e adolescentes (CA) com Doença Falciforme (DF). Dos 120 usuários elegíveis de um serviço público hematológico, 106 CA entre 6 e 18 anos de idade, e seus cuidadores, responderam questões semiestruturadas sobre condições sociodemográficas, de saúde e saúde bucal. Para a QLV, o instrumento validado PedsQL DF® foi aplicado. Na sequência, realizou-se o exame clínico bucal nas CA segundo diretrizes da OMS e do SB Brasil 2010. A maioria das CA era negra (88%), idade média de 10,4 (±2.9) anos, renda familiar de até dois salários mínimos, para 03 a 05 membros, diagnosticadas na triagem neonatal com anemia falciforme, internadas por crises álgicas, em uso de polifarmácia e com cárie dental (51%). O domínio “Sobre o Impacto da Minha Dor” foi preditivo da QLVDF (R² ajustado =56%; AIC=28.67; p=0,04). Nele, a cárie dental na dentição permanente piorou a QLVDF das CA (OR=0.53; IC95%=0.35-0.78; p<0,05), associando-se ao tipo de escola, posse de carro e do número de membros na família, de complicações da DF e de medicamentos. Os achados ratificam a dor como marca da DF e mostram a importância da saúde bucal na QLDF das CA. A implementação de políticas públicas específicas pode superar esse cenário.

Resumo A marula (Sclerocarya birrea) pertencente à família Anacardiaceae, é originária do bioma das savanas da África do Sul e da região da África oriental. É uma das árvores nativas mais valorizadas do sul da África por possuir propriedades medicinais e nutricionais de grande valor, entretanto existe um entrave na sua produção que é a dormência das sementes. Assim, objetivou-se com este trabalho avaliar a influência do tempo de armazenamento na superação da dormência e na qualidade fisiológica de sementes de marula. O delineamento experimental utilizado foi o inteiramente casualizado, utilizando-se 400 sementes distribuídas aleatoriamente em 4 repetições de 100 sementes para analise biométrica. Para avaliação da qualidade fisiológica e superação da dormência das sementes os tratamentos consistiram em cinco períodos de armazenamento: 10 dias (testemunha); e 184; 244; 306; 367 e 428 dias após o colheita, com quatro repetições de 25 sementes por tratamento. Recomenda-se, o armazenamento das sementes de marula durante 367 dias após a colheita em condições ambientais (26±2 °C), por apresentarem melhor qualidade fisiológica.

Abstract Marula (Sclerocarya birrea) is a species of the family Anacardiaceae, native to the savanna biome in South and East Africa. It is among the most valued native trees of southern Africa due to its medicinal and nutritional properties; however, the dormancy of its seeds makes the production of marula difficult. Thus, the objective of this work was to evaluate the effect of storage times on dormancy breaking and physiological quality of marula seeds. A completely randomized experimental design was used, with four 100-seed replications for evaluating seed biometry. Physiological quality and dormancy breaking were evaluated through treatments consisted of five storage periods: 10 (control), 184, 244, 306, 367, and 428 days after harvest, with four 25-seed replications per treatment. Storing marula seeds under room conditions (26±2 °C) for 367 days after harvest is recommended for a better physiological quality of the seeds.

Objective: To associate abandonment of tuberculosis treatment with the variables of access to health services in the state of São Paulo was estimated. Methods: was an epidemiological observational study with data to individuals diagnosed with tuberculosis, residing in the state of São Paulo in the period 2012 to 2017. Generalized Estimating Equations models were used to analyze the relationships between independent variables and noncompliance with tuberculosis treatment over time. Results: A prevalence of over 12% of noncompliance with tuberculosis treatment was identified. Individuals residing in medium and large-sized municipalities had, 2.64 (95% CI: 2.15-3;24) and 4.48 (CI 95%: 4.62-5.55) times more risk, respectively, of abandoning TB treatment when compared with those living in small cities (p&lt;0.05). Moreover, presence of Psychosocial Care Centers did not contribute to the reduction of treatment abandonment [1.20 (1.03-1.40) p&lt;0.05]. Conclusions: Was an association between municipal size and abandonment of tuberculosis treatment.

Introdução: Estimou-se a associação entre o abandono do tratamento da tuberculose com variáveis de acesso ao serviço de saúde no estado de São Paulo. Métodos: Trata-se de um estudo epidemiológico ecológico com fonte de dados secundários de indivíduos diagnosticados com tuberculose, no período de janeiro/2012 a dezembro/2017 residentes no estado de São Paulo. A variável desfecho é o abandono do tratamento da tuberculose. Foram efetuadas análises e considerada a distribuição de Poisson, estimados os riscos relativos brutos e ajustados, dispostas em dois blocos de variáveis considerando nível de significância de 5%. Resultados: Identificou-se uma prevalência superior a 12% no abandono do tratamento da TB no estado de São Paulo no período estudado. Indivíduos residentes em municípios de médio e grande porte têm, respectivamente, 2,64 (IC95%: 2,15-3,24) e 4,48 (IC95%: 4,62-5,55) vezes mais risco de abandonar o tratamento da TB quando comparados ao que vivem em municípios pequeno porte (p&lt;0,05), bem como, municípios com a presença do CAPS não contribuíram para a diminuição do abandono [1,20 (1,03-1,40) p&lt;0,05]. Conclusão: houve associação entre o porte municipal e o abandono do tratamento de Tuberculose.

Abstract Ascorbate peroxidases (APXs) are heme peroxidases involved in the control of hydrogen peroxide levels and signal transduction pathways related to development and stress responses. Here, a total of 238 APX, 30 APX-related (APX-R), and 34 APX-like (APX-L) genes were identified from 24 species from the Poaceae family. Phylogenetic analysis of APX indicated five distinct clades, equivalent to cytosolic (cAPX), peroxisomal (pAPX), mitochondrial (mitAPX), stromal (sAPX), and thylakoidal (tAPX) isoforms. Duplication events contributed to the expansion of this family and the divergence times. Different from other APX isoforms, the emergence of Poaceae mitAPXs occurred independently after eudicot and monocot divergence. Our results showed that the constitutive silencing of mitAPX genes is not viable in rice plants, suggesting that these isoforms are essential for rice regeneration or development. We also obtained rice plants silenced individually to sAPX isoforms, demonstrating that, different to plants double silenced to both sAPX and tAPX or single silenced to tAPX previously obtained, these plants do not show changes in the total APX activity and hydrogen peroxide content in the shoot. Among rice plants silenced to different isoforms, plants silenced to cAPX showed a higher decrease in total APX activity and an increase in hydrogen peroxide levels. These results suggest that the cAPXs are the main isoforms responsible for regulating hydrogen peroxide levels in the cell, whereas in the chloroplast, this role is provided mainly by the tAPX isoform. In addition to broadening our understanding of the core components of the antioxidant defense in Poaceae species, the present study also provides a platform for their functional characterization.

Resumo A dupla mãe-filho está inserida em um sistema social que gera diversas influências nas práticas alimentares, inclusive nos primeiros seis meses de vida, período em que é preconizado o aleitamento materno exclusivo pela Organização Mundial da Saúde. Objetivo: Compreender o conjunto de influências sociais que incidem nas práticas alimentares adotadas pela nutriz e para o seu filho nos primeiros seis meses de vida. Método: Estudo qualitativo, com abordagem metodológica de análise descrito por Minayo e alicerçado na fenomenologia social de Alfred Schütz. Participaram oito duplas mãe-filho recrutados de dois hospitais públicos de Salvador-BA com a Iniciativa Hospital Amigo da Criança. Realizou-se entrevista semiestruturada no domicílio das mães aos seis meses de vida da criança no período de junho a agosto de 2019. Resultados: Emergiram três tipificações: o fazer “correto” nos primeiros seis meses de vida da criança; as ações de cuidados com as práticas alimentares da mulher-mãe que amamenta; e o mundo social da dupla mãe-filho. Conclusão: para a tomada de decisão sobre as práticas alimentares da nutriz, a mãe exerceu mais influência; já para a criança, a nutriz considerou as orientações recebidas pelos profissionais de saúde.

Abstract The mother-child pair is inserted in a social system that generates different influences on eating practices, including in the first six months of life, a period in which exclusive breastfeeding is recommended by the World Health Organization. Objective: To understand the set of social influences that affect the eating habits adopted by the nursing mother and her child in the first six months of life. Method: Qualitative study, with a methodological analysis approach described by Minayo and based on the social phenomenology of Alfred Schütz. Eight mother-child pairs recruited from two public hospitals in Salvador-BA with the Amigo da Criança Hospital Initiative participated. A semi-structured interview was carried out at the mothers' homes when the child was six months old, from June to August 2019. Results: Three typifications emerged: doing “correctly” in the first six months of the child's life; care actions with the feeding practices of the woman-mother who breastfeeds; and the social world of the mother-son duo. Conclusion: For decision-making about the nursing mother's eating practices, the mother exerted more influence; for the child, the nursing mother considered the guidelines received by health professionals.

Abstract This study aimed to estimate the cost of implementing a center for assisted human reproduction in a public reference hospital in Rio de Janeiro. The cost analysis was carried out from the perspective of the SUS provider of assistance. The eligible population was men and women diagnosed with the most frequent causes of infertility. The cost items included in primary care and medium complexity were consultations and examinations and in high complexity were equipment, human resources and supplies. Costs were identified and quantified through consultation with assisted reproduction clinics, specialists and literature. They have been valued through public databases. Data analysis was performed using an analytical decision model that included costs of assisted reproduction and effectiveness procedures. The cost per procedure in high complexity was R$ 18,829 for in vitro fertilization with intracytoplasmic sperm injection and R$ 5,649 for artificial insemination. The initial investment required to operate the high complexity center for 480 cycles was R$ 15,903,361 in the first year, which included structuring the physical environment. Estimating the investment required for the incorporation and maintenance of services in SUS is essential for the management of available financial resources.

Resumen: El objetivo fue identificar los relatos de síntomas de depresión, ansiedad y estrés entre cuidadores de niños sin discapacidad visual, con baja visión y con ceguera y su relación con el grado de apoyo social, emocional, material y afectivo. Estudio transversal y multicéntrico realizado en la ciudad de Río de Janeiro, Brasil, entre el 2019 y el 2020. Se aplicó un cuestionario para obtener datos sociodemográficos y económicos del cuidador. Se utilizaron la Escala de Apoyo Social (The Medical Outcomes Study Social Support Scale - MOS-SSS) y Escala de Depresión, Ansiedad y Estrés (The Depression, Anxiety, and Stress Scale - DASS-21). Al comparar las escalas, se utilizaron pruebas para comparaciones múltiples. Se estimó la razón de prevalencia de síntomas de depresión, ansiedad y estrés. Del total de cuidadores (N = 355), más del 90% eran mujeres madres y la mayor proporción de cuidadores sin escolaridad o con primaria incompleta y con menor ingreso mensual promedio fueron los de niños con discapacidad visual. La mayoría de los cuidadores de niños con ceguera reportó síntomas de depresión, ansiedad y estrés, respectivamente, 66,7%, 73,3% y 80%, mismo comportamiento observado en el grupo de cuidadores de niños con baja visión. Al evaluar la relación entre los resultados de las escalas MOS-SSS y DASS-21, entre los cuidadores de niños sin discapacidad o con menor compromiso visual, se observó mayor apoyo y menores puntajes de relatos de depresión, ansiedad y estrés. Entre los cuidadores de niños ciegos, la mayor prevalencia de tales relatos no dependió del apoyo recibido. Los resultados indican la necesidad de una Política de Cuidado con mecanismos para proteger la salud mental de los cuidadores de niños con discapacidad visual.

Abstract: We aimed to identify the reports of symptoms of depression, anxiety, and stress among caregivers of children without visual impairment, with low vision, and with blindness and their relationship with the degree of social, emotional, material, and affective support. This cross-sectional and multicenter study was conducted in the municipality of Rio de Janeiro, Brazil, from 2019 to 2020. A questionnaire was applied to obtain caregivers’ sociodemographic and economic data. The Medical Outcomes Study Social Support Scale (MOS-SSS) and The Depression, Anxiety, and Stress Scale (DASS-21) were used. Tests were used for multiple comparisons of these scales. The prevalence ratio of symptoms of depression, anxiety, and stress was estimated. Of all caregivers (N = 355), more than 90% were women-mothers. Caregivers of children with visual impairment show the highest proportion of no schooling, incomplete elementary education, or lower average monthly income. Most caregivers of children with blindness reported symptoms of depression, anxiety, and stress (66.7%, 73.3%, and 80%, respectively) as did those of children with low vision. The evaluation of the relationship between MOS-SSS and DASS-21 results shows greater support and lower scores of reports of depression, anxiety, and stress for caregivers of children without disabilities or with less visual impairment. For caregivers of blind children, the highest prevalence of such reports was independent of the received support. Results indicate the need for a care policy with mechanisms to protect the mental health of caregivers of visually impaired children.

Entre os cuidadores de crianças cegas, as maiores prevalências não dependeram dos apoios recebidos. Os resultados indicam a necessidade de uma política de cuidado com mecanismos de proteção à saúde mental dos cuidadores de crianças com deficiência visual.

Abstract Monteverdia ilicifolia (Mart. ex Reissek) Biral (basionym: Maytenus ilicifolia Mart. ex Reissek) (Celastraceae) is popularly known as holy thorn or “espinheira-santa” in Brazil. This herb is traditionally used for gastric and digestive problems. However, similar species are often used as adulterants. Considering the pharmacological interest and the existence of adulterants, this study was devoted to characterizing M. ilicifolia samples by Fourier-transform infrared (FTIR) spectroscopy coupled with principal component analysis (PCA) and photoacoustic spectroscopy (PAS) by using Citronella gongonha (Mart.) R. A. Howard as adulterant sample. Six commercial samples were purchased, and seven collected samples were obtained in the Campos Gerais region. The leaves were then dehydrated and converted to powder. The FTIR spectroscopic assay was carried out and consisted of ten different measurements for each sample with a time interval of seven days between them. The PCA was performed from these spectra. The characterization by FTIR demonstrated the presence of tannins and flavonoids in the studied samples. FTIR spectroscopy coupled with PCA was able to discriminate the commercial and the collected samples of M. ilicifolia using three principal components. The photoacoustic spectroscopy resulted in absorption bands centered at ~280, ~380, ~480, and ~630 nm. These bands presented a higher spectral resolution for the collected samples. The commercial samples showed broadening bands, which allowed the differentiation between these two sets of samples. FTIR spectroscopy coupled with PCA, and photoacoustic spectroscopy are alternative tools for the differentiation of M. ilicifolia samples.

Abstract Eugenol is a phenolic compound with numerous biological activities. It is widely used in dentistry to treat toothache and pulpitis. In particular, eugenol may be used for tooth whitening procedures to minimize dental sensitivity in patients. However, eugenol has some disadvantages such as its volatility, its photosensitivity, and immediate effect, which can be avoided by using pharmaceutical nanotechnology. The aim of the present study was to obtain, characterize, quantify, and evaluate the physicochemical stability of eugenol-loaded Eudragit RS100 nanocapsules. The nanocapsules (NCs) were prepared by interfacial deposition of the preformed polymer method. The NCs were characterized through morphological and spectroscopic studies. The encapsulation efficiency was achieved by quantifying the non-encapsulated eugenol using a previously developed and validated analytical method. The physicochemical stability of NCs was assessed at predetermined time intervals for 90 days after preparation. The nanocapsules were successfully prepared by the chosen method and had a predominantly spherical shape with a smooth surface. The mean size, the polydispersion index, and the zeta potential were in agreement to literature data. Infrared spectra ensured that the nanoencapsulation process did not result in chemical reactions between the drug and the polymer. The formulations showed encapsulation efficiency higher than 90% and remained stable after 60 days of preparation. Thus, eugenol-loaded Eudragit RS100 nanocapsules may be further considered as an alternative formulation for dental sensitivity in order to provide a controlled release, a decreased toxicity, and a better dental sensitivity relief.

Abstract The establishment of epigenetic marks during the reprogramming window is susceptible to environmental influences, and stimuli during this critical stage can cause altered DNA methylation in offspring. In a previous study, we found that low levels of sulphur and cobalt (low S/Co) in the diet offered to oocyte donors altered the DNA methylome of bovine embryos. However, due to the extensive epigenetic reprogramming that occurs during embryogenesis, we hypothesized that the different methylation regions (DMRs) identified in the blastocysts may not maintain in adulthood. Here, we aimed to characterize DMRs previously identified in embryos, in the blood and sperm of adult progenies of two groups of heifers (low S/Co and control). We used six bulls and characterized the DNA methylation levels of KDM2A, KDM5A, KMT2D, and DOT1L genes. Our results showed that all DMRs analysed in both groups and tissues were hypermethylated unlike that noticed in the embryonic methylome profiles. These results suggest that embryo DMRs were reprogrammed during the final stages of de novo methylation during embryogenesis or later in development. Therefore, due to the highly dynamic epigenetic state during early embryonic development, we suggest that is essential to validate the DMRs found in embryos in adult individuals.

BACKGROUND Dendritic cells (DCs) specific intercellular adhesion molecule (ICAM)-3-grabbing non integrin receptor (DC-SIGN) binds to subgenera Leishmania promastigotes mediating its interaction with DC and neutrophils, potentially influencing the infection outcome. OBJECTIVES In this work, we investigated whether DC-SIGN receptor is expressed in cells from cutaneous leishmaniasis (CL) lesions as well as the in vitro binding pattern of Leishmania (Viannia) braziliensis (Lb) and L. (L.) amazonensis (La) promastigotes. METHODS DC-SIGN receptor was labeled by immunohistochemistry in cryopreserved CL tissue fragments. In vitro binding assay with CFSE-labeled Lb or La promastigotes and RAJI-transfecting cells expressing DC-SIGN (DC-SIGNPOS) or mock-transfected (DC-SIGNNEG) were monitored by flow cytometry at 2 h, 24 h and 48 h in co-culture. RESULTS In CL lesion infiltrate, DC-SIGNPOS cells were present in the dermis and near the epidermis. Both Lb and La bind to DC-SIGNPOS cells, while binding to DC-SIGNNEG was low. La showed precocious and higher affinity to DC-SIGNhi population than to DC-SIGNlow, while Lb binding was similar in these populations. CONCLUSION Our results demonstrate that DC-SIGN receptor is present in L. braziliensis CL lesions and interact with Lb promastigotes. Moreover, the differences in the binding pattern to Lb and La suggest DC-SIGN can influence in a difference way the intake of the parasites at the first hours after Leishmania infection. These results raise the hypothesis that DC-SIGN receptor could participate in the immunopathogenesis of American tegumentary leishmaniasis accounting for the differences in the outcome of the Leishmania spp. infection.

ABSTRACT Aedes (Stegomyia) albopictus (Skuse, 1854) was reported in Brazil for the first time in 1986 and has shown marked expansion throughout the Brazilian territory. During a routine activity to control dengue fever conducted by the Division of Entomology of the Municipal Health Department in Rio Branco city, adults and immatures of Culicidae were collected in a peri-urban area. The identified Culicidae forms indicated that they belonged to the species Ae. albopictus. This is the first official record of the presence of Ae. albopictus in the Acre State, confirming its current presence in all Brazilian states.

ABSTRACT Objective To evaluate the consumption of free sugars and associated factors in the diet of university students entering full-time courses at a public university in Mato Grosso. Methods Cross-sectional study with students aged 16 to 26 years in the first semester of 2016, 2017, and 2018. Average sugar consumption was estimated using a 24-hour diet recall, evaluating the percentage of free sugars in total energy intake and the prevalence of consumption greater than 10.0% of total energy intake, according to socioeconomic and lifestyle variables, stratified by sex, and the foods that most contributed to its consumption. Results A total of 1,063 students were evaluated, the percentage of free sugars in the students’ diet was on average 14.3% among men and 15.4% among women, with the prevalence of consumption above 10.0% also being higher among women (72.6 vs. 66.6%). There was a direct relationship between the participation of free sugars in the highest tertiles of energy intake, and the main food groups sources of sugar were desserts, juices, soft drinks, and coffee. There was a significant association between courses outside the health sciences, tobacco use, and unsatisfactory meal consumption profile with higher consumption of free sugars among women. Among men, sugar consumption was higher among those who were not overweight compared to those who were overweight.

RESUMO Objetivo Avaliar o consumo de açúcar livre e os fatores associados na alimentação de universitários ingressantes em cursos de período integral em uma universidade pública de Mato Grosso. Métodos Estudo transversal com estudantes de 16 a 26 anos de idade no primeiro semestre de 2016, 2017 e 2018 (n=1.063). O consumo médio de açúcar foi estimado por meio de recordatório de 24 horas, sendo avaliada a participação do açúcar livre na ingestão energética total e a prevalência de participação do consumo superior a 10,0% da ingestão energética, segundo variáveis socioeconômicas, de estilo de vida e fatores dietéticos, , estratificadas por sexo. Resultados A participação do açúcar livre na dieta foi, em média, de 14,3% entre os homens e 15,4% entre as mulheres, sendo a prevalência de consumo acima de 10,0% também maior entre as mulheres (72,6 vs. 66,6%). Foi maior a participação do açúcar livre nos tercis mais elevados de ingestão energética, sendo verificado que os principais grupos de alimentos fontes foram sobremesas, sucos, refrigerantes e café. Entre as mulheres, verificou-se maior consumo de açúcar livre entre aquelas que faziam uso de tabaco e que apresentavam perfil de consumo de refeições insatisfatório. Por outro lado, menor consumo de açúcar livre foi observado entre as estudantes da área da saúde. Entre os homens, o consumo de açúcar livre foi maior entre aqueles sem excesso de peso, comparados aos com excesso. Conclusão O consumo de açúcar livre foi elevado entre estudantes universitários, sendo maior entre os estudantes com maior consumo energético. Verificou-se que as bebidas adoçadas estiveram entre as principais fontes.
