ABSTRACT Introduction: HIV/AIDS is considered one of the great cases of public health, but it is seen that patients who use antiretroviral therapy (ART) and practice strength training promote a promotion of their health. Objectives: Assess the impact of strength and resistance training on cytokines and body composition in people living with HIV/AIDS. Methods: Randomized clinical trial, the sample consisted of 12 patients, 7 from the Strength Group (GF) and 5 from Group 2, Muscular Resistance (MGR). We compared the levels of IL-2, IL-4, IL-6, IL-10 and TNF-α cytokines and body composition in the first and last sessions. The patients completed 36 strength and resistance training sessions over 12 weeks. Results: After 36 sessions of GRM resistance training, there was a significant increase from 4,734 pg/mL to 5,050 pg/mL of IL-10 (p=0.002). Regarding the GFR, no significant results were found. For body composition, there were significant differences in GFR due to the increase in lean mass of the arms from 6,441g to 7,014g (p=0.04), legs from 16,379g to 17,281g (p=0.02) and whole body of 45,640g to 47,343g (p=0.01). In G2 there was a significant decrease in the percentage of fat in the arms from 23,160% to 20,750% (p = 0.04). To assess quality of life, the WHOQOL-HIV-Bref questionnaire was used, where significant improvement was found in all domains, except for the level of independence domain. Conclusion: We conclude that muscular resistance training is effective in increasing IL-10 and decreasing the percentage of fat in the arms, whereas strength training increases lean mass in arms, legs, and the whole body. Level of Evidence I; Randomized Clinical Trial.

RESUMEN Introducción: El VIH/SIDA es considerado uno de los grandes casos de salud pública, sin embargo, está comprobado que pacientes que hacen uso de la terapia antirretroviral (TARV) y practican entrenamiento de fuerza provoca una promoción de su salud. Objetivos: Evaluar el impacto del entrenamiento de fuerza en la resistencia a las citoquinas y en la composición corporal de las personas que viven con VIH/SIDA. Métodos: Ensayo clínico aleatorizado, la muestra estuvo compuesta por 12 pacientes, siete del Grupo de Fuerza (TFG) y cinco del Grupo de Resistencia Muscular (GRM). Se compararon los niveles de las citocinas IL-2, IL-4, IL-6, IL-10 y TNF-α y la composición corporal en la primera y la última sesión. Los pacientes completaron 36 sesiones de entrenamiento de fuerza y resistencia durante 12 semanas. Resultados: Tras 36 sesiones de entrenamiento de resistencia GRM, se produjo un aumento significativo de 4.734 pg/mL a 5.050 pg/mL de IL-10 (p=0,002). En cuanto a la TFG, no se encontraron resultados significativos. En cuanto a la composición corporal, hubo diferencias significativas en la TFG debido al aumento de la masa magra en brazos de 6.441g a 7.014g (p=0,04), piernas de 16.379g a 17.281g (p=0,02) y cuerpo entero de 45.640g a 47.343g (p=0,01). En el GRM hubo una disminución significativa del porcentaje de grasa en los brazos de 23.160% a 20.750% (p = 0,04). Para la evaluación de la calidad de vida se utilizó el cuestionario WHOQOL-HIV-Bref, donde se encontró una mejoría significativa en todos los dominios, excepto en el dominio nivel de independencia. Conclusión: Concluimos que el entrenamiento de resistencia muscular es eficaz para aumentar la IL-10 y disminuir el porcentaje de grasa en los brazos, mientras que el entrenamiento de fuerza aumenta la masa magra total. Nivel de Evidencia I; Ensayo clínico aleatorizado.

RESUMO Introdução: O HIV/AIDS é considerado um dos grandes casos de saúde pública, porém verifica-se que pacientes que fazem uso de terapia antirretroviral (TARV) e praticam treinamento de força provocam uma promoção de sua saúde. Objetivos: Avaliar o impacto do treinamento de força sobre a resistência nas citocinas e a composição corporal de pessoas vivendo com HIV/AIDS. Métodos: Ensaio clínico randomizado, a amostra foi composta por 12 pacientes, sendo sete do Grupo Força (TFG) e cinco do Grupo Resistência Muscular (GRM). Comparou-se os níveis das citocinas IL-2, IL-4, IL-6, IL-10 e TNF-α e a composição corporal na primeira e na última sessão. Os pacientes completaram 36 sessões de treinamento de força e resistência ao longo de 12 semanas. Resultados: Após 36 sessões de treinamento resistido GRM, houve um aumento significativo de 4.734 pg/mL para 5.050 pg/mL de IL-10 (p=0,002). Em relação à TFG, não foram encontrados resultados significativos. Para composição corporal, houve diferenças significativas na TFG devido ao aumento da massa magra dos braços de 6.441g para 7.014g (p=0,04), pernas de 16.379g para 17.281g (p=0,02) e corpo inteiro de 45.640g para 47.343g (p=0,01). No GRM houve diminuição significativa do percentual de gordura nos braços de 23.160% para 20.750% (p = 0,04). Para avaliação da qualidade de vida foi utilizado o questionário WHOQOL-HIV-Bref, onde foi encontrada uma melhora significativa em todos os domínios, exceto no domínio nível de independência. Conclusão: Conclui-se que o treinamento de resistência muscular é eficaz em aumentar a IL-10 e diminuir o percentual de gordura nos braços, enquanto o treinamento de força aumenta a massa magra geral.

ABSTRACT Sweet potato is among the most important food crops in the world. Due to its high genetic diversity, this species has cultivars that can respond in different ways depending on mineral fertilization. Among the nutrients, phosphorus is related to physiological and biochemical processes that can influence the final quality of the product. This study aimed to assess the influence of P doses on the quality and bioactive compounds of sweet potato cultivars - Paraná, BRS Amélia, and BRS Cuia. The pH, soluble solids (SS), titratable acidity (TA), SS/TA ratio, soluble sugars, and the bioactive compounds - flavonoids, anthocyanins, and carotenoids - were evaluated. The P doses influenced sweet potato cultivars. The dose of 120 kg ha-1 promoted increments in the parameters pH, SS, TA, and SS/TA ratio for the cultivar BRS Cuia. The same dose promoted an increase in total soluble sugars for the cultivar BRS Amélia. P dose of 240 kg ha-1 promoted higher levels of flavonoids and anthocyanins in the cultivar Paraná, and there was an increase in carotenoid content at the dose of 60 kg ha-1.

RESUMO A batata-doce está entre as culturas alimentícias mais importantes do mundo. Por apresentar alta diversidade genética, essa espécie possui cultivares que podem responder de maneiras diferentes em função da adubação mineral. Dentre os nutrientes, o fósforo está relacionado com processos fisiológicos e bioquímicos que podem influenciar na qualidade final do produto. Este estudo teve como objetivo avaliar a influência de doses de P na qualidade e compostos bioativos de cultivares de batata-doce - Paraná, BRS Amélia e BRS Cuia. Foram avaliados o pH, sólidos solúveis (SS), acidez titulável (AT), relação SS/AT, açúcares solúveis e os compostos bioativos - flavonoides, antocianinas e carotenoides. As doses de P influenciaram as cultivares de batata-doce. A dose de 120 kg ha-1 promoveu incrementos nos parâmetros pH, SS, AT e relação SS/AT para a cultivar BRS Cuia. A mesma dose promoveu incrementos nos açúcares solúveis totais para a cultivar BRS Amélia. A dose de 240 kg ha-1 promoveu maiores teores de flavonoides e antocianinas na cultivar Paraná, e houve aumento no teor de carotenoides na dose de 60 kg ha-1.

Abstract The iAtlantic Project has established an international collaborative strategy to improve mapping and characterization of deep and open ocean ecosystems in understudied regions of the Atlantic and evaluate their health. In December 2022, the first iAtlantic expedition in the South Atlantic set off to map and explore seafloor ecosystems in the Santos Basin slope (200-1,000 m depths) in collaboration with the Petrobras ‘Santos Basin - Regional Characterization Project.’ The 17-day ‘iAtlantic_BR10-Petrobras’ cruise was conducted on board the research vessel NPqHOc Vital de Oliveira (Brazilian Navy) and performed (a) water column structure characterization, (b) seafloor morphology mapping, (c) description of benthic habitats and communities by seafloor imagery and biological/ geological sampling, and (d) ex-situ experiments to assess the functioning of sedimentary ecosystems and their responses to climate-related environmental changes. This study describes the rationale behind the iAtlantic_BR10-Petrobras cruise science plan, reports its sampling strategy and methods, and summarizes its collected data and preliminary results.

ABSTRACT The Atlantic Forest is made up of different vegetation types over extensive latitude. Most of its remnants are in mountain ranges, which are responsible for the maintenance of most endemic and threatened species in this domain. Here we present the floristic composition of the Área de Proteção Ambiental Mestre Álvaro (APAMA), a coastal massif at Espírito Santo State with expressive altitudinal amplitude (100-800 a.s.l.) containing remnants never floristically studied. Knowing the composition of this protected area is important because it includes an altitudinal range not yet evaluated in floristic comparisons involving highland and lowland forests between the latitudes 18-21° S. We found 493 species (in 292 genera and 91 families): ten are regional endemic species, nine are new records of occurrence for the state, and 52 are under some degree of threat of extinction. Our results indicate the presence of flora elements' typical of both highland and lowland forests, which makes the APAMA essential in a scenario extremely fragmented. Finally, our data provide an unprecedented floristic list for regional forest restoration projects, as well as an invaluable source of data for biogeographic studies that seek to understand the effect caused by neighboring vegetation types on the composition of lowland forests.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Resumo A Mata Atlântica brasileira guarda importante porção da riqueza de anfíbios e altas taxas de endemismos. Neste estudo, nós realizamos pesquisas usando o Método de Avaliação Rápida (RA) com o objetivo de inventariar a fauna de anfíbios de um remanescente da Mata Atlântica no sudeste do Brasil, o Monumento Natural Serra das Torres (MONAST). Amostramos ativamente com uma equipe de 6 a 10 pessoas para coletar amostras padronizadas entre 09:00 e 12:00 horas durante o peíodo diurno e entre 18:00 e 22:00 duranto período crepuscular/noturno, totalizando aproximadamente 1320 horas de esforço amostral. Complementamos estes dados com 720 horas de amostragem passiva usando armadilhas de queda com cercas-guia (30 dias de balde). Registramos 54 espécies de anfíbios (dois gimnofionos e 52 anuros) e a riqueza de espécies estimada pelo Bootstrap indicou um número relativamente maior de espécies (n = 60). A família mais especiosa foi Hylidae (n = 21), seguida por Brachycephalidae (n = 8). No geral, 25% das espécies (n = 13) foram registradas apenas uma vez - singletons e 15% (n = 8) apenas duas vezes (doubletons). A maioria dos anfíbios registrados neste estudo (71%, n = 37 espécies) esteve restrita ao bioma Mata Atlântica, duas espécies (Euparkerella robusta e Luetkenotyphlus fredi) são endêmicas do estado do Espírito Santo, sendo uma delas, a espécie de serapilheira E. robusta, endêmica do MONAST. Euparkerella robusta está atualmente listada como Vulnerável pela IUCN e classificada como Criticamente Ameaçada na lista vermelha do estado do Espírito Santo, enquanto L. fredi ainda não foi avaliada devido a sua descrição ser muito recente. Thoropa lutzi está atualmente listada como Ameaçada (EN) pela IUCN e na lista estadual. Nove espécies estão listadas como Deficiente de Dados (DD) e as populações de 13 espécies são consideradas em declínio pela IUCN. Estendemos a distribuição geográfica de duas espécies de anuros (Hylodes babax e Phasmahyla lisbella) e preenchemos uma importante lacuna na distribuição de Siphonops hardyi. Os anfíbios associados ao chão da floresta representaram 42% das espécies do MONAST e 43% destas espécies habitavam exclusivamente a serapilheira. Nosso estudo revelou que a Serra das Torres preserva diversidade considerável de anfíbios da Mata Atlântica, o que reforça a necessidade de conservação desse remanescente florestal.

Abstract The Brazilian Atlantic Forest holds a major part of the country’s amphibian species richness and high rates of endemism. In this study, we conducted surveys using the Rapid Assessment (RA) method to sample the amphibian fauna of the Serra das Torres Natural Monument (MONAST), an Atlantic Forest remnant in southeastern Brazil. We sampled actively with a 6-10-person team to collect standard samples from 09:00 to 12:00 hours for the daytime period, and from 18:00 to 22:00 hours for the crepuscular/nighttime period, with a total of approximately 1,320 hours of sampling effort. We supplemented these data with 720 hours of passive sampling, using pitfall traps with drift fences (30 bucket-days). We recorded 54 amphibian species (two gymnophionans and 52 anurans), and the species richness estimated by the Bootstrap method indicates that a slightly larger number of species (n = 60) may occur in the study area. The most speciose family was Hylidae (n = 21), followed by Brachycephalidae (n = 8). Overall, 25% of the species (n = 13) were recorded only once (singletons) and 15% (n = 8) only twice (doubletons). Most amphibians recorded in this study (71%, n = 37 species) were restricted to the Atlantic Forest biome, two species (Euparkerella robusta and Luetkenotyphlus fredi) are endemic to the Espírito Santo state, and one of them, the leaf litter species E. robusta, is endemic to the MONAST. Euparkerella robusta is currently listed as Vulnerable by the IUCN and is classified as Critically Endangered in the Espírito Santo State red list, while L. fredi has yet to be evaluated due to its recent description. Thoropa lutzi is currently listed as Endangered (EN) by both the IUCN and in the State list. Nine species are listed as Data Deficient (DD) and populations of 13 species are considered to be declining by the IUCN. We extend the geographical distribution of two anuran species (Hylodes babax and Phasmahyla lisbella) and fill an important gap in the distribution of Siphonops hardyi. Amphibians associated with the forest floor represented 42% of the species richness from MONAST, and 43% of these species inhabit the leaf litter exclusively. Our study revealed that Serra das Torres preserves a considerable diversity of Atlantic Forest amphibians, which reinforces the need for the conservation of this forest remnant.

Abstract: Currently, the research of new natural compounds with biological potential demonstrates great ethnopharmacological importance. In this study, we evaluated the biological properties promoted by saline extract from Malpighia emarginata DC leaves, whose objective is to evaluate the antioxidant, antimicrobial and cytotoxicity potential. Phytochemical characterization was performed by UPLC-MS chromatography to identify the chemical compounds. For the antioxidant potential, DPPH, ATT and FRAP methods were used. The antibacterial and antifungal tests were performed evaluating the MIC50, MIC90, CMB and CMF parameters. Moreover, antibiofilm action was evaluated. Cytotoxicity and proliferation were performed using splenocytes from Balb/c mice and were evaluated by cytometry. We found a list of phenolic compounds among other bioactive compounds in the M. emarginata saline extract. In addition, higher antioxidant profile and antifungal activity against different strains of Candida spp. was promoted by the saline extract. Splenocytes showed greater cell viability (more than 90%) and showed higher proliferate index in 24 and 48 hours of incubation with the extract. Saline extract from Malpighia emarginata DC has potential action like antioxidant and antifungal agent without promote animal cell damage.

Abstract The response of plants to grazing includes the production of chemical defense compounds such as proteases inhibitors and secondary metabolites as flavonoids, which makes them less palatable to feeding and negatively affecting the physiology of insects. The aim of this study was to evaluate the phytochemical response of soybean cultivars (Glycine max (L.) Merrill) resistant (IAC-17, IAC-24) and susceptible (IAC-P1) to insects after mechanical damage. These cultivars were mechanically injured, and after 24 hours samples of these plants were analyzed by HPLC to identify and quantify flavonoids. The flavonoids daidzein, quercetin, and rutin were quantified, with the highest concentration of daidzin in soybean cultivars after mechanical damage. Rutin was biosynthesized by IAC-24. The cultivars IAC-PL1, IAC-17, and IAC-24 did not show a flavonoid response to mechanical damage. The soybean cultivars are not dependent on mechanical damage to produce flavonoids.

Resumo Objetivo: Avaliar as manifestações clínicas da hiperexpressão de hormônios do córtex da adrenal e câncer familiar como marcadores para a detecção precoce de tumores adrenocorticais em crianças do Sul e Sudeste do Brasil. Pacientes e métodos: Foram analisadas as manifestações clínicas e antropométricas de 103 crianças diagnosticadas com tumores adrenocorticais. Resultados: Entre 1982 e 2011, 69 meninas e 34 meninos diagnosticados com tumores adrenocorticais foram acompanhados por um tempo mediano de nove anos (0-34). Ao diagnóstico, sinais de virilização isolada (n = 75) ou associada ao cortisol (n = 18) estavam presentes em 90,3% dos pacientes; a mutação do gene TP53 p.R337H foi identificada em 90,5% dos pacientes. Os pacientes foram classificados em estádio I (45,6%), II (27,2%), III (19,4%) e IV (7,8%). Ao diagnóstico, não houve diferença significativa para as medidas de altura (p = 0,92) e de peso (p = 0,22) entre as crianças com tumores adrenocorticais, mas crianças com virilização tiveram escore-Z mais elevado para a idade (0,92 ± 1,4) do que aquelas com hipercortisolismo isolado ou combinado (−0,32 ± 1,8; p = 0,03). A sobrevida global de cinco anos foi de 76,7% (DP ± 4,2). Pacientes com estádios avançados tiveram pior prognóstico (p < 0,001). Durante o seguimento, 10 dos 55 genitores portadores da p.R337H desenvolveram câncer, enquanto que nenhum caso ocorreu entre os 55 não portadores. Conclusões: Os sinais de hiperprodução de hormônios adrenocorticais aparecem precocemente no desenvolvimento do tumor e podem ser identificados pelo exame físico e pelas medidas antropométricas na consulta pediátrica de rotina. O tumor adrenocortical pediátrico é sentinela para a detecção de câncer em famílias que segregam a mutação germinativa p.R337H do gene TP53.

Abstract Objective: To evaluate the clinical features associated with adrenocortical hormone overexpression and familial cancer profiling as potential markers for early detection of adrenocortical tumors in children from South and Southeast Brazil. Methods: The clinical manifestations and anthropometric measurements of 103 children diagnosed with adrenocortical tumors were analyzed. Results: Between 1982 and 2011, 69 girls and 34 boys diagnosed with adrenocortical tumors were followed-up for a median time of 9.0 years (0-34 years). Signs of androgen overproduction alone (n = 75) or associated with cortisol (n = 18) were present in 90.3%. TP53 p.R337H mutation was found in 90.5% of patients. Stages I, II, III, and IV were observed in 45.6%, 27.2%, 19.4%, and 7.8% of patients, respectively. At diagnosis, there were no significant differences in height (p = 0.92) and weight (p = 0.22) among children with adrenocortical tumors, but children with virilization alone had significantly higher height-for-age Z-scores (0.92 ± 1.4) than children with hypercortisolism alone or combined (−0.32 ± 1,8; p = 0.03). The five-year overall survival was 76.7% (SD ± 4.2). Patients with advanced-stage disease had a significantly worse prognosis than those with limited disease (p < 0.001). During follow-up, ten of 55 p.R337H carrier parents developed cancer, whereas none of the 55 non-carriers did. Conclusions: Signs of adrenocortical hormone overproduction appear early, even in cases with early-stage. These signs can be identified at the physical examination and anthropometric measurements. In southern Brazil, pediatric adrenocortical tumor is a sentinel cancer for detecting families with germline p.R337H mutation in TP53 gene.

RESUMO Objetivou-se neste estudo avaliar a sorção do sulfametoxazol, onde a cinética e as isotermas de sorção foram determinadas em duas camadas de solo Neossolo Regolítico Eutrófico típico (camadas 0-20 e 20-60 cm) da reserva particular da fazenda Riacho do Papagaio, São João, PE. Os ensaios foram realizados em laboratório a 24 ºC, pelo método “batch”, e a concentração de sulfametoxazol determinada por cromatografia líquida de alta eficiência. Nos ensaios de cinética de sorção foi utilizada solução de sulfametoxazol na concentração de 10-4 mol L-1, enquanto para as isotermas de sorção foram utilizadas soluções nas concentrações de 10-3, 5.10-4, 10-4, 5.10-5, 10-5 e 5.10-6 mol L-1. Para esse solo, as cinéticas de sorção do sulfametoxazol foram melhor descritas com um modelo de segunda ordem e as isotermas de sorção foram lineares. Para este tipo de solo, a interação do sulfametoxazol é predominantemente com a matéria orgânica, apresentando baixa adsorção, evidenciando um maior risco de contaminação das águas subterrâneas existentes nessa região em pH ≈ 7.

ABSTRACT This study aimed to evaluate sulfamethoxazole sorption kinetics and isotherms using batch method. The experiment was carried out in typic eutrophic Regolithic Neosol (0-20 and 20-60 cm layers) located in the private reserve of the Riacho do Papagaio farm, in São João, PE, Brazil. The tests were carried out under laboratory conditions at 24 ºC and sulfamethoxazole concentration was determined by high-performance liquid chromatography. The sorption experiment through the batch method used sulfamethoxazole solutions with concentrations of 10-3, 5.10-4, 10-4, 5.10-5, 10-5 and 5.10-6 mol L-1 to obtain the analytical curve. For this soil, sulfamethoxazole sorption kinetics was best described by a second-order model and the sorption isotherms were linear. Sulfamethoxazole predominantly interacts with organic matter in this type of soil. The results obtained in this study show that the antibiotic sulfamethoxazole exhibits low adsorption, posing a higher risk of contamination to the groundwaters in this region at pH ≈ 7.

RESUMO O trabalho objetivou avaliar a produtividade de híbridos de milho-verde sob irrigação cultivados em diferentes populações de plantas na semeadura. Foi conduzido na área experimental localizada no município de Arapiraca, AL, no período de novembro de 2015 a janeiro de 2016. O delineamento experimental utilizado foi em blocos casualizados, em esquema fatorial 2 x 5, com quatro repetições. Foram analisados dois híbridos, duplo e simples, indicados para milho verde (AG 1051 e BM 3061) e cinco espaçamentos entre plantas na semeadura (15,0; 17,5; 20,0; 22,5 e 25 cm). Foram avaliadas as características: taxa fotossintética (TF), comprimento de espigas com palha (CECP) e sem palha (CESP), peso de espigas com palhas (PECP) e sem palhas (PESP), porcentagem de espigar comerciais (%EC) e peso da palha (PP). Os híbridos duplo e simples, 1051 e BM 3061, apresentam espigas verdes com padrão comercial. A cultivar BM 3061 possui melhor desempenho para a maioria das características relacionadas ao desempenho da cultura (TF, CECP, CESP, PP, PECP, PESP, %EC). O espaçamento de 17,5 cm entre plantas na semeadura mostrou-se mais indicado para o cultivo do milho-verde irrigado.

ABSTRACT This study aimed to evaluate the yield of green corn hybrids grown under irrigation in different plant populations at sowing. The assay was carried out in the experimental area located in the city of Arapiraca, Alagoas State, Brazil, from November 2015 to January 2016. A randomized complete block design (RCBD) was used, in a 2 x 5 factorial scheme with four replicates. A double- and a single-cross hybrid (AG 1051 and BM 3061), which are suitable for green corn production, were cultivated in five spacings between plants at sowing (15.0, 17.5, 20.0, 22.5 and 25.0 cm). The characteristics photosynthetic rate (PR), ear length with rusk (HEL) and without husk (UEL), husked ear weight (HEW), unhusked ear weight (UEW), percentage of marketable ears (%ME) and weight of husk (HW) were evaluated. The double- and single-cross hybrids AG 1051 and BM 3061 showed green ears with commercial standard. The cultivar BM 3061 showed the best results for most of the characteristics related to the performance of green corn (PR, HEL, UEL, UEW, HEW, %ME). The spacing of 17.5 cm between plants at sowing was the most indicated for irrigated green corn cultivation.

Resumo Objetivo: Analisar as variáveis demográficas e clínicas associadas à diminuição da qualidade de vida em uma grande coorte brasileira de pacientes com espondiloartrite (EpA). Métodos: Foi aplicado um protocolo de pesquisa único a 1.465 pacientes brasileiros classificados como tendo EpA de acordo com os critérios do European Spondyloarthropaties Study Group (ESSG), atendidos em 29 centros de referência em reumatologia do Brasil. Foram registradas as variáveis clínicas e demográficas. A qualidade de vida foi analisada por meio do questionário Ankylosing Spondylitis Quality of Life (ASQoL). Resultados: A pontuação média do ASQoL foi de 7,74 (+ 5,39). Ao analisar doenças específicas no grupo de EpA, as pontuações do ASQoL não apresentaram diferença estatisticamente significativa. Os dados demográficos mostraram piores escores de ASQoL associados ao gênero feminino (p = 0,014) e etnia negra (p < 0,001). Quanto aos sintomas clínicos, a dor na região glútea (p = 0,032), a dor cervical (p < 0,001) e a dor no quadril (p = 0,001), estiveram estatisticamente associadas a piores escores no ASQoL. O uso contínuo de fármacos anti-inflamatórios não esteroides (p < 0,001) e agentes biológicos (p = 0,044) esteve associado a escores mais elevados de ASQoL, enquanto outros medicamentos não interferiram nos escores do ASQoL. Conclusão: Nesta grande série de pacientes com EpA, o sexo feminino e a etnia negra, bem como sintomas predominantemente axiais, estiveram associados a uma qualidade de vida reduzida.

Abstract Objective: To analyze quality of life and demographic and clinical variables associated to its impairment in a large Brazilian cohort of patients with spondyloarthritis (SpA). Methods: A common protocol of investigation was applied to 1465 Brazilian patients classified as SpA according to the European Spondyloarthropaties Study Group (ESSG) criteria, attended at 29 reference centers for Rheumatology in Brazil. Clinical and demographic variables were recorded. Quality of life was analyzed through the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. Results: The mean ASQoL score was 7.74 (± 5.39). When analyzing the specific diseases in the SpA group, the ASQoL scores did not present statistical significance. Demographic data showed worse scores of ASQoL associated with female gender (p = 0.014) and African-Brazilian ethnicity (p < 0.001). Regarding clinical symptoms, buttock pain (p = 0.032), cervical pain (p < 0.001) and hip pain (p = 0.001), were statistically associated with worse scores of ASQoL. Continuous use of nonsteroidal anti-inflammatory drugs (p < 0.001) and biologic agents (p = 0.044) were associated with higher scores of ASQoL, while the other medications did not interfere with the ASQoL scores. Conclusion: In this large series of patients with SpA, female gender and African-Brazilian ethnicity, as well as predominant axial symptoms, were associated with impaired quality of life.

Objetivo Avaliar os resultados da aplicação do Índice de Atividade de Doença da Espondilite Anquilosante de Bath (BASDAI) numa série de pacientes brasileiros com EpA e estabelecer suas correlações com as variáveis específicas do grupo. Métodos Um protocolo comum de investigação foi prospectivamente aplicado em 1.492 pacientes brasileiros classificados como EpA pelos critérios do Grupo Europeu de Estudo das Espondiloartropatias (ESSG), acompanhados em 29 centros de referência em reumatologia no Brasil. Variáveis clínicas, demográficas e índices de doença foram colhidos. Os valores totais do BASDAI foram comparados com a presença das diferentes variáveis. Resultados O valor médio do BASDAI foi de 4,20 ± 2,38. Os escores médios do BASDAI foram mais elevados nos pacientes com forma clínica combinada, comparado às formas axiais e periféricas isoladas, nos pacientes do sexo feminino e nos sedentários. Com relação ao componente axial, valores mais altos do BASDAI estiveram significativamente associados à lombalgia inflamatória, à dor alternante em nádegas, à dor cervical e ao acometimento de coxofemorais. Houve associação estatística entre os valores do BASDAI e o comprometimento periférico, relacionado ao número de articulações inflamadas, tanto dos membros inferiores quanto dos membros superiores, e às entesites. A positividade do HLA-B27 e a presença de manifestações extra-articulares não estiveram correlacionadas com os valores médios do BASDAI. Valores mais baixos do BASDAI estiveram associados ao uso de agentes biológicos (p < 0,001). Conclusão Nesta série heterogênea de pacientes brasileiros com EpA, o BASDAI conseguiu demonstrar “atividade de doença” tanto nos pacientes com acometimento axial quanto naqueles com envolvimento periférico.

Objective To analyze the results of the application of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in a large series of Brazilian patients with the diagnosis of SpA and establish its correlations with specific variables into the group. Methods A common protocol of investigation was prospectively applied to 1492 Brazilian patients classified as SpA according to the European Spondyoarthropathies Study Group (ESSG), attended at 29 referral centers of Rheumatology in Brazil. Clinical and demographic variables, and disease indices (BASDAI, Basfi, Basri, Mases, ASQol) were applied. The total values of BASDAI were compared to the presence of the different variables. Results The mean score of BASDAI was 4.20 ± 2.38. The mean scores of BASDAI were higher in patients with the combined (axial + peripheral + entheseal) (4.54 ± 2.38) clinical presentation, compared to the pure axial (3.78 ± 2.27) or pure peripheral (4.00 ± 2.38) clinical presentations (P < 0.001). BASDAI also presented higher scores associated with the female gender (P < 0.001) and patients who did not practice exercises (P < 0.001). Regarding the axial component, higher values of BASDAI were significantly associated with inflammatory low back pain (P < 0.049), alternating buttock pain (P < 0.001), cervical pain (P < 0.001) and hip involvement (P < 0.001). There was also statistical association between BASDAI scores and the peripheral involvement, related to the lower (P = 0.004) and upper limbs (P = 0.025). The presence of enthesitis was also associated to higher scores of BASDAI (P = 0.040). Positive HLA-B27 and the presence of cutaneous psoriasis, inflammatory bowel disease, uveitis and urethritis were not correlated with the mean scores of BASDAI. Lower scores of BASDAI were associated with the use of biologic agents (P < 0.001). Conclusion In this heterogeneous Brazilian series of SpA patients, BASDAI was able to demonstrate “disease activity” in patients with axial as well as peripheral disease.

A espectrometria de absorção atômica em forno de grafite de alta resolução com fonte contínua (HR-CS GF AAS) é proposta para determinar Pb em sombra de olho e blush empregando a análise direta de sólidos. O emprego da mistura de modificadores químicos Pd(NO3)2 + Mg(NO3)2 possibilitou a calibração aquosa de 0,25 a 2,5 ng Pb (r = 0,998). O desempenho do método proposto foi avaliado por meio da análise de digeridos de sombra e de blush por espectrometria de absorção atômica em forno de grafite com fonte de linhas (LS GF AAS) como técnica comparativa. Os resultados obtidos por HR-CS GF AAS e LS GF AAS foram concordantes entre si a um nível de confiança de 95% (teste t pareado). O limite de quantificação (massa seca) foi de 0,020 ng mg–1. A concentração de Pb nas amostras de sombra de olho e de blush variou de 1,222 a 9,632 ng mg–1 e 0,362 a 28,091 ng mg–1, respectivamente.

Direct solid sampling is proposed for Pb determination in eye shadow and blush samples by high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS). A mixture of Pd(NO3)2 + Mg(NO3)2 was employed as chemical modifier, and aqueous calibration (0.25-2.5 ng Pb, r = 0.998) was obtained. Accuracy of the determination of Pb in eye shadow and blush samples by the proposed method was verified by line source graphite furnace AAS as a comparative technique employing digested samples. The results obtained by the two methods were in agreement at a 95% confidence level (paired t-test). The limit of quantification (dry mass) was 0.020 ng mg–1. The Pb content in the eye shadow and blush samples varied between 1.222 and 9.632 ng mg–1 and 0.362 and 28.091 ng mg–1, respectively.
