Abstract Objective: To describe the health-related quality of life (QOL) in children with cerebral palsy (CP) associated with congenital Zika infection. Methods: Cross-sectional study of a consecutive series of children, followed in a referral multicentric rehabilitation network in Brazil. We invited the caregivers to respond to the Brazilian version of the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM) questionnaire. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) 26.0™. We used absolute and relative frequencies for categorical variables and mean and standard deviation for continuous variables. Results: The sample consisted of 193 children, at mean age of 50.3±7.6 months. We observed a predominance of children with cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level V (93.7%). Epilepsy (88.4%) was the most common comorbidity. CPCHILDTM mean scores were activities of daily living (ADL)/personal care 43.2±12.6; positioning, transferring and mobility 33.7±16.5; comfort and emotions 84.4±15.2; communication and social interaction (CoSI) 48.2±24.3; health 70.9±17.1; and overall quality of life (OQOL) 72.1±17.1. Total score was 54.8±11.3. Conclusions: Among children with cerebral palsy (CP) related to congenital Zika syndrome, the quality of life (QOL) scores were very similar to other populations with cerebral palsy (CP). The activities of positioning, transferring and mobility had the greatest impact on health-related quality of life (QOL). Rehabilitation strategies and public policies should prioritize aspects related to mobility for this population.

RESUMO Objetivo: Descrever a qualidade de vida relacionada à saúde em crianças com paralisia cerebral associada à infecção congênita pelo zika. Métodos: Estudo transversal de série consecutiva de casos de crianças acompanhadas em uma rede multicêntrica de reabilitação no Brasil. Convidamos o(s) cuidador(es) a responder à versão brasileira do Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM). A análise estatística foi realizada com o pacote estatístico Statistical Package for the Social Sciences (SPSS) 26.0™. Para variáveis categóricas, foram utilizadas frequências absolutas e relativas e, para variáveis contínuas, média e desvio padrão. Resultados: Cento e noventa e três crianças, com idade média de 50,3±7,6 meses, foram incluídas. Observou-se predomínio de crianças com paralisia cerebral Gross Motor Function Classification System (GMFCS) nível V (93,7%). Epilepsia (88,4%) foi a comorbidade mais comum. As pontuações médias do CPCHILDTM foram: atividades de vida diária/cuidados pessoais 43,2±12,6; posicionamento, transferência e mobilidade 33,7±16,5; conforto e emoções 84,4±15,2; comunicação e interação social 48,2±24,3; saúde 70,9±17,1; e qualidade de vida geral 72,1±17,1. A pontuação total foi 54,8±11,3. Conclusões: Entre as crianças com paralisia cerebral relacionada à síndrome do zika congênita, as atividades de posicionamento, transferência e mobilidade tiveram maior impacto na qualidade de vida relacionada à saúde, semelhantemente a outras etiologias de paralisia cerebral. As estratégias de reabilitação e as políticas públicas devem priorizar os aspectos relacionados à mobilidade dessa população.

Abstract Objective: To provide guidelines on the coronavirus disease 2019 (COVID-19) vaccination in patients with immune-mediated rheumatic diseases (IMRD) to rheumatologists considering specific scenarios of the daily practice based on the shared-making decision (SMD) process. Methods: A task force was constituted by 24 rheumatologists (panel members), with clinical and research expertise in immunizations and infectious diseases in immunocompromised patients, endorsed by the Brazilian Society of Rheumatology (BSR), to develop guidelines for COVID-19 vaccination in patients with IMRD. A consensus was built through the Delphi method and involved four rounds of anonymous voting, where five options were used to determine the level of agreement (LOA), based on the Likert Scale: (1) strongly disagree; (2) disagree, (3) neither agree nor disagree (neutral); (4) agree; and (5) strongly agree. Nineteen questions were addressed and discussed via teleconference to formulate the answers. In order to identify the relevant data on COVID-19 vaccines, a search with standardized descriptors and synonyms was performed on September 10th, 2021, of the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and LILACS to identify studies of interest. We used the Newcastle–Ottawa Scale to assess the quality of nonrandomized studies. Results: All the nineteen questions-answers (Q&A) were approved by the BSR Task Force with more than 80% of panelists voting options 4—agree—and 5—strongly agree—, and a consensus was reached. These Guidelines were focused in SMD on the most appropriate timing for IMRD patients to get vaccinated to reach the adequate covid-19 vaccination response. Conclusion: These guidelines were developed by a BSR Task Force with a high LOA among panelists, based on the literature review of published studies and expert opinion for COVID-19 vaccination in IMRD patients. Noteworthy, in the pandemic period, up to the time of the review and the consensus process for this document, high-quality evidence was scarce. Thus, it is not a substitute for clinical judgment.

Resumo Pterodon pubescens e P. emarginatus (Leguminosae) são duas espécies de plantas nativas medicinais do Brasil. As populações têm sido ameaçadas pelo extrativismo para uso de suas propriedades terapêuticas. Estudos de diversidade genética ajudam a racionalizar o uso e a promover a conservação dessas espécies. Nós desenvolvemos marcadores microssatélites para P. pubescens e transferimos para P. emarginatus com intuito de permitir investigações futuras da diversidade genética das espécies. A partir de sequências genômicas de P. pubescens, obtidas via plataforma Illumina MiSeq, foi possível identificar 6.514 regiões microssatélites, desenhar 5.419 pares de primers, e testar a amplificação de 30 marcadores. Nós fornecemos 26 marcadores moleculares, 10 dos quais foram usados para genotipar 48 indivíduos de cada espécie. O número de alelos por locus variou de 3 a 16, com alta diversidade genética média para ambas as espécies ( P. pubescens HE = 0,753; P. emarginatus HE = 0,691). Os dez marcadores apresentaram boa probabilidade de exclusão de falsa paternidade (com valores acima de 0,99) e baixos valores de probabilidade de identidade, indicando que esse conjunto é adequado para discriminar indivíduos em P. pubescens e P. emarginatus. Os marcadores microssatélites desenvolvidos neste trabalho representam uma ferramenta promissora para estudos de genética de populações e conservação das duas espécies e podem, eventualmente, ser aplicados a espécies não-modelos filogeneticamente próximas.

Abstract Pterodon pubescens and P. emarginatus (Leguminosae) are native medicinal plants of Brazil. Extractivism due to its therapeutic properties threatens populations of both species. Studies of genetic diversity is a way to reason the use and promote conservation. We developed microsatellite markers for P. pubescens and transferred them to P. emarginatus to further genetic diversity investigation of these species. From genomic sequences of P. pubescens, obtained via the Illumina MiSeq platform, it was possible to identify 6,514 microsatellite regions, to design 5,419 primer pairs, and to test 30 markers amplification. We provide 26 polymorphic microsatellite markers, 10 of which were genotyped in 48 individuals per species. The number of alleles per locus range from 3 to 16, with high average genetic diversity ( P. pubescens HE = 0.753; P. emarginatus HE = 0.691). The genotyped markers have a high paternity exclusion probability (Q values greater than 0.99) and low probability of identity, indicating that set of loci is capable of individual discriminating in P. pubescens and P. emarginatus. Microsatellite markers provided in this study are a tool for population genetics studies and conservation of the two species and can be applied to closely related non-model species.

Resumo Objetivo Avaliar a evidência disponível acerca da transmissão vertical do coronavírus da síndrome respiratória aguda grave 2 (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2, em inglês). Fontes de Dados Foi realizada uma busca eletrônica em 13 de junho de 2020 nas plataformas Embase, PubMed e “Scopus utilizando os seguintes termos de busca: (Coronavirus OU COVID-19 OU COVID19 OU SARS-CoV-2 OU SARS-CoV2 OU SARSCoV2) E (vertical OU pregnancy OU fetal). Seleção dos Estudos A busca eletrônica resultou em um total de 2.073 registros. Títulos e resumos foram revisados por dois autores (WPM, IDESB), que verificaram a ocorrência de duplicidade e utilizaram critérios preestabelecidos para o rastreamento (estudos publicados em inglês sem limitações quanto à data ou à situação da publicação). Aquisição dos Dados A extração de dados foi realizada de forma padrão, e a eligibilidade final foi definida poir meio da leitura do artigo completo. Foram coletados dados dos partos de casos com potencial transmissão vertical, bem como os principais achados e conclusões de revisões sistemáticas. Síntese dos Dados Foram revisados os 2.073 registros; 1.000 duplicatas e 896 registros claramente não elegíveis foram excluídos. Avaliamos os artigos completos de 177 registros, e identificamos apenas 9 casos de potencial transmissão vertical. O único caso com evidência suficiente de transmissão vertical foi relatado na França. Conclusão O risco de transmissão vertical pelo vírus SARS-CoV-2 é provavelmente muito baixo. Apesar de milhares de gestantes afetadas, identificamos apenas um caso que preencheu critérios suficientes para que fosse confirmado como um caso de transmissão vertical. Estudos observacionais bem desenhados que avaliem grandes amostras ainda são necessários para se determinar o risco de transmissão vertical, a depender da idade gestacional na infecção.

Abstract Objective The evaluation of the available evidence on vertical transmission by severe acute respiratory syndrome coronavirus 2 (SARS-CoV)-2. Data Sources An electronic search was performed on June 13, 2020 on the Embase, PubMed and Scopus databases using the following search terms: (Coronavirus OR COVID-19 OR COVID19 OR SARS-CoV-2 OR SARS-CoV2 OR SARSCoV2) AND (vertical OR pregnancy OR fetal). Selection of Studies The electronic search resulted in a total of 2,073 records. Titles and abstracts were reviewed by two authors (WPM, IDESB), who checked for duplicates using the pre-established criteria for screening (studies published in English without limitation regarding the date or the status of the publication). Data Collection Data extraction was performed in a standardized way, and the final eligibility was assessed by reading the full text of the articles. We retrieved data regarding the delivery of the potential cases of vertical transmission, as well as themain findings and conclusions of systematic reviews. Data Synthesis The 2,073 records were reviewed; 1,000 duplicates and 896 clearly not eligible records were excluded. We evaluated the full text of 177 records, and identified only 9 suspected cases of possible vertical transmission. The only case with sufficient evidence of vertical transmission was reported in France. Conclusion The risk of vertical transmission by SARS-CoV-2 is probably very low. Despite several thousands of affected pregnant women, we have identified only one case that has fulfilled sufficient criteria to be confirmed as a case of vertical transmission. Well-designed observational studies evaluating large samples are still necessary to determine the risk of vertical transmission depending on the gestational age at infection.

ABSTRACT The search for techniques that maximize the use of water is becoming necessary for the sustainability of agriculture in semi-arid areas. In this sense, the present work aimed to evaluate the effects of soil protection against water loss and the use of bovine biofertilizer on fruit production and chlorophyll content in bell pepper plants. The experiment was conducted in the municipal district of Nova Floresta in the semi-arid region of the State of Paraíba during the period of August 2010 to February 2011. The experimental design was a randomized block design with four repetitions in a 2 × 2 × 2 factorial scheme, corresponding to soil without and with bovine biofertilizer, without and with mulch, and without and with side coating of the grooves with polyethylene film, to reduce water loss through evaporation and lateral movement of water. The results showed that the use of side coatings of the grooves led to greater production, generating productivity gains in bell pepper cultivation. The association between side coating of the grooves and mulching of the soil resulted in increased levels of chlorophyll, but the bovine biofertilizer × side coating × mulch interaction inhibited the production of chlorophyll in the plants.

Abstract Background: There is a lack of information on the role of chronic use of hydroxychloroquine during the SARS-CoV-2 outbreak. Our aim was to compare the occurrence of COVID-19 between rheumatic disease patients on hydroxychloroquine with individuals from the same household not taking the drug during the first 8 weeks of community viral transmission in Brazil. Methods: This baseline cross-sectional analysis is part of a 24-week observational multi-center study involving 22 Brazilian academic outpatient centers. All information regarding COVID-19 symptoms, epidemiological, clinical, and demographic data were recorded on a specific web-based platform using telephone calls from physicians and medical students. COVID-19 was defined according to the Brazilian Ministry of Health (BMH) criteria. Mann-Whitney, Chi-square and Exact Fisher tests were used for statistical analysis and two binary Final Logistic Regression Model by Wald test were developed using a backward-stepwise method for the presence of COVID-19. Results: From March 29th to May 17st, 2020, a total of 10,443 participants were enrolled, including 5166 (53.9%) rheumatic disease patients, of whom 82.5% had systemic erythematosus lupus, 7.8% rheumatoid arthritis, 3.7% Sjögren’s syndrome and 0.8% systemic sclerosis. In total, 1822 (19.1%) participants reported flu symptoms within the 30 days prior to enrollment, of which 3.1% fulfilled the BMH criteria, but with no significant difference between rheumatic disease patients (4.03%) and controls (3.25%). After adjustments for multiple confounders, the main risk factor significantly associated with a COVID-19 diagnosis was lung disease (OR 1.63; 95% CI 1.03-2.58); and for rheumatic disease patients were diagnosis of systemic sclerosis (OR 2.8; 95% CI 1.19-6.63) and glucocorticoids above 10 mg/ day (OR 2.05; 95% CI 1.31-3.19). In addition, a recent influenza vaccination had a protective effect (OR 0.674; 95% CI 0.46-0.98). Conclusion: Patients with rheumatic disease on hydroxychloroquine presented a similar occurrence of COVID-19 to household cohabitants, suggesting a lack of any protective role against SARS-CoV-2 infection. Trial registration Brazilian Registry of Clinical Trials (ReBEC; RBR - 9KTWX6).

ABSTRACT The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.

Resumen: En | Texto: En | PDF: En

Abstract Background: In Brazil, we are facing an alarming epidemic scenario of Yellow fever (YF), which is reaching the most populous areas of the country in unvaccinated people. Vaccination is the only effective tool to prevent YF. In special situations, such as patients with chronic immune-mediated inflammatory diseases (CIMID), undergoing immunosuppressive therapy, as a higher risk of severe adverse events may occur, assessment of the risk-benefit ratio of the yellow fever vaccine (YFV) should be performed on an individual level. Main body of the abstract: Faced with the scarcity of specific orientation on YFV for this special group of patients, the Brazilian Rheumatology Society (BRS) endorsed a project aiming the development of individualized YFV recommendations for patients with CIMID, guided by questions addressed by both medical professionals and patients, followed an internationally validated methodology (GIN-McMaster Guideline Development). Firstly, a systematic review was carried out and an expert panel formed to take part of the decision process, comprising BRS clinical practitioners, as well as individuals from the Brazilian Dermatology Society (BDS), Brazilian Inflammatory Bowel Diseases Study Group (GEDIIB), and specialists on infectious diseases and vaccination (from Tropical Medicine, Infectious Diseases and Immunizations National Societies); in addition, two representatives of patient groups were included as members of the panel. When the quality of the evidence was low or there was a lack of evidence to determine the recommendations, the decisions were based on the expert opinion panel and a Delphi approach was performed. A recommendation was accepted upon achieving ≥80% agreement among the panel, including the patient representatives. As a result, eight recommendations were developed regarding the safety of YFV in patients with CIMID, considering the immunosuppression degree conferred by the treatment used. It was not possible to establish recommendations on the effectiveness of YFV in these patients as there is no consistent evidence to support these recommendations. Conclusion: This paper approaches a real need, assessed by clinicians and patient care groups, to address specific questions on the management of YFV in patients with CIMID living or traveling to YF endemic areas, involving specialists from many areas together with patients, and might have global applicability, contributing to and supporting vaccination practices. We recommended a shared decision-making approach on taking or not the YFV.

RESUMO As colunas de percolação, construídas em Laboratório, podem predizer o grau de contaminação nos solos receptores do rejeito da dessalinização da água, podendo ser uma ferramenta de prevenção a impactos ambientais. O presente trabalho objetivou avaliar a mobilização de íons presentes nos rejeitos salinos proveniente do processo de dessalinização das águas salobras. A mobilização dos íons contaminante no rejeito salino foi estudada em colunas de percolação construída de vidro, as quais foram preenchidas com solos de textura contrastante (CAMBISSOLO Eutrófico, LATOSSOLO Vermelho distrófico, NEOSSOLO Quartzarênico), com três repetições cada, sendo analisada as suas concentrações inicial e final dos íons contaminantes. Para a avaliação do potencial de poluição deste resíduo foi determinado o fator de retardamento e o coeficiente de difusão-dispersão dos íons K+, Cl- e Na+ para cada solo estudado. Houve diferença das curvas de deslocamento dos íons presentes no rejeito salino entre os tipos de solos. O Neossolo apresentou maior velocidade de avanço dos íons K+ e Cl-, ou seja, maior poder de contaminação em subsuperfície para estes íons. No Latossolo, os íons deslocam-se com maior facilidade e, portanto, maior facilidade de contaminação do lençol freático. No Cambissolo houve baixos valores de coeficiente de difusão-dispersão em todos os íons avaliados, ou seja, menor mobilidade dos íons, sendo diretamente influenciados pelos respectivos teores trocáveis.

ABSTRACT Percolation columns constructed in the Laboratory can predict the degree of contamination in soil due to reject brine disposal and can be a tool for reducing environmental impacts. This study aim to evaluate the mobilization of ions in reject brine from desalination process by reverse osmosis. The mobilization of the contaminant ions in the saline waste was studied in glass percolation columns, which were filled with soil of contrasting textures (eutrophic CAMBISOL, typic dystrophic Red OXISOL, ENTISOL Quartzipsamment). Experiments ware repeated three times each, and the initial and final concentrations of the ion contaminants were analyzed. The pollution potential of this wastewater was determined by the retardation factor and dispersion-diffusion coefficient of K+, Cl- and Na+ for each studied soil. The differences in the displacement curves of the ions present in the saline waste among various soil types were analyzed. The Entisol Quartzipsamment showed a higher forward speed of the ions K+ and Cl- (greater retardation factor, i.e., greater power of the subsurface contamination for these ions). In typic dystrophic Red OXISOL, the ions move with greater ease and therefore produced greater groundwater contamination. In eutrophic CAMBISOL, the low coefficient of diffusion-dispersion in all ions was evaluated (i.e., reduced ion mobility is directly influenced by their exchangeable levels).

Objetivou-se avaliar o efeito da aplicação de esterco bovino líquido e uréia no crescimento e na alocação de biomassa nos diferentes órgãos do maracujazeiro amarelo. O experimento foi desenvolvido no período de setembro de 2006 a dezembro de 2007, no município de Remígio - PB. O delineamento experimental foi o de blocos ao acaso com três repetições e três plantas por parcela, totalizando 180 plantas para observação, usando esquema fatorial 5 x 2, referente ao esterco bovino líquido (ELB) nas proporções em água (A) de 0% (0ELB + 4A); 25% (1ELB + 3A); 50% (2ELB + 2A); 75% (3ELB + 1A) e 100% (4ELB + 0A), tomando 4 L planta-1 da mistura como volume padrão no solo sem e com nitrogênio, fornecido a cada 30 dias após o plantio até o final do experimento. Aos 420 dias após o plantio foi obtido o diâmetro do caule, contado o número de ramos produtivos e as plantas foram divididas em raízes, caules, ramos laterais, ramos produtivos e folhas para avaliação da matéria seca das partes constituintes do maracujazeiro amarelo. Pelos resultados se constatou que a interação esterco líquido bovino x nitrogênio exerceu efeitos significativos sobre o diâmetro do caule, número de ramos produtivos, biomassa das raízes, do caule, das folhas, dos ramos laterais e dos ramos produtivos, em que os valores na maioria dos casos aumentaram com os percentuais do esterco líquido de bovino, mas com superioridade nos tratamentos com uréia.

This study was carried out in order to evaluate the effect of liquid cattle manure and urea on dry matter production in different parts of yellow passion fruit plants. The experiment was conducted during the period of September 2006 to December 2007, in Remígio county Paraiba State, Brazil. The experimental design was randomized blocks with three replications using the factorial squeme 5 x 2 referring to liquid cattle manure (CLM) diluted with water (W) at levels 0% (0CLM + 4W); 25% (1CLM + 3W); 50% (2CLM + 2W); 75% (3CLM + 1W) and 100% (4CLM + 0W) taking 4 L plant-1 as standard volume of each mixture in soil without and with nitrogen applied monthly from 30 days after the planting to the end of the experiment. At 420 days after planting, were obtained the stem diameter and the number of productive branches of the plants; then, the plants were collected, each plant was divided in root, stem, lateral and productive branches and was obtained the dry matter of each part of the plant. The results showed that the interaction liquid cattle manure x nitrogen exercise significant effect on stem diameter, productive branches and biomass of the root, stem, leaves, lateral and productive branches, but with statistic superiority to plants with cattle liquid manure and urea applied to the soil.

A avaliação da qualidade do solo é uma ferramenta importante para monitorar a sua degradação, bem como planejar a implantação de práticas sustentáveis de manejo. Neste trabalho, objetivou-se avaliar indicadores biológicos de qualidade do solo em um Latossolo Amarelo distrófico, submetido a diferentes sistemas de uso em Areia-PB. Foram utilizadas amostras de solo coletadas na camada arável (0-20 cm) em áreas de mata nativa, fruticultura, cana-de-açúcar, sucessão de cultivos, pastagem e consórcio de culturas. Foram avaliados o carbono orgânico total (COT), carbono da biomassa microbiana (CBM), quociente microbiano (qMic), respiração basal (RB) e quociente metabólico (qCO2). Os resultados obtidos indicaram que as áreas sob gramíneas apresentaram uma tendência de manutenção do COT e menores reduções no CBM, entretanto, apresentaram elevados valores de qCO2, indicando a ocorrência de um processo degradativo. A área sob fruticultura apresentou leves reduções no COT e CBM e baixos valores de qCO2, indicando que esse sistema pode estar se ajustando a um novo estado de equilíbrio. As áreas sob sucessão de cultivos e consórcio de culturas apresentaram as maiores reduções no COT e CBM e elevados valores de qCO2, demonstrando um elevado estágio de degradação desses sistemas. Pode-se concluir que todos os sistemas agrícolas estudados promoveram perda de qualidade do solo, sendo esse fato mais pronunciado nas áreas sob manejo mais intensivo. O CBM e qCO2 mostraram-se bastantes sensíveis às alterações decorrentes do uso agrícola do solo, apresentando grande potencial para estudos de sua qualidade.

Soil quality evaluation is an important tool for the monitoring of soil degradation as well as for planning the adoption of sustainable agricultural management practices. The objective of this study was to evaluate some biological indicators of the soil quality of a dystrophic Yellow Latosol (Oxisol) under different land use systems in Areia, Paraíba, Brazil. Soil samples were taken form the plow layer (0-20 cm) at six sites: native vegetation (moist Atlantic forest), fruit culture (cashew crop), sugarcane, crop succession (sorghum/common bean/castor bean), pasture (Brachiaria decumbens), and a combined cropping system (castor bean + sorghum). Total organic carbon (TOC), microbial biomass carbon (MBC), microbial quotient (qMic), basal respiration (BR) and metabolic quotient (qCO2) were evaluated. The results indicated that treatments under grasses, such as sugarcane and pasture, showed a tendency to maintain the TOC contents with lower reductions in MBC. However, higher qCO2 values were found under these treatments, which may indicate the occurrence of degradation processes. Slight reductions in TOC and MBC values and low qCO2 values were verified in the cashew crop, suggesting that the soil under this system could be adjusting to a new equilibrium state. Crop succession and combined cropping system treatments had the largest reductions in TOC and MBC with the highest qCO2 values, which suggests a stage of advanced degradation. It can be concluded that all the agroecosystems evaluated in this study resulted in loss of soil quality, which was pronounced in the most intensively managed treatments. The MBC and qCO2 were highly sensitive to land use changes and show great potential for soil quality evaluations.

Este estudo objetivou construir uma proposta pedagógica com alunos de nível fundamental na comunidade de São Miguel, Esperança (PB). Procurou-se despertar o interesse dos estudantes para a importância do solo em suas vidas, bem como adequar a terminologia usada na pedologia à linguagem cotidiana dos alunos. Seguiu-se como método a abordagem paulofreireana na qual se considera que o contexto da escola extrapola o da sala de aula, devendo envolver o máximo de pessoas da comunidade. Assim, procurou-se levantar informações quanto à renda familiar, moradia, número de irmãos e irmãs, atividade principal do responsável pela família, etc. Deste levantamento, extraiu-se, também, o vocabulário mínimo, com palavras e expressões geradoras que sintetizam o universo de conhecimento em São Miguel. Os resultados denotaram a dureza do cotidiano e uma educação repressiva diante da indomabilidade dos filhos. Observou-se que elementos pedagógicos presentes no vocabulário mínimo podem facilitar a popularização do saber pedológico no ensino fundamental. O vocabulário mínimo promoveu uma melhor comunicação durante as aulas entre educadores e educandos, bem como permitiu a construção de conceitos para as ordens de solos mais representativas da região: Neossolos e Argissolos. A construção de monólitos de solos constituiu importante recurso auxiliar nas aulas expositivas e dialógicas, despertando nas crianças maior interesse para o tema solo e meio ambiente.

This work aimed at creating an educational project with elementary school students from the São Miguel community in Esperança county, state of Paraiba, Brazil. We encouraged the children to think about the importance of soil in their life, and also tried to use a pedologic terminology adapted to the students' everyday language. The applied methodology followed Paulo Freire's approach, which extrapolates the school context from the classroom and tries to reach out for as many people in the community as possible. Thus, information was collected on the families income, housing type, number of brothers and sisters, main occupation of the family head, etc. A minimum vocabulary, with words and expressions that synthesize São Miguel's overall knowledge, was extracted from this initial survey. Results reflect the hard life and a repressive education when it comes to children's rebelliousness. Pedagogic elements present in the minimum vocabulary suggest that pedologic knowledge could be popularized in elementary schools. The minimum vocabulary promoted a better communication between educators and students during classes. It also favored the construction of concepts for the most representative soils types - Entisols and Ultisols. The construction of soil monoliths represented an important part of the expository and dialogue classes, arousing the interest of children for the soil and environment subjects.

A Mimosa caesalpiniaefolia Benth. é uma espécie nativa da região Nordeste, que vem sendo progressivamente cultivada do Maranhão ao Rio de Janeiro. A planta apresenta grande potencial para arborização, cerca viva e produção de madeira. O presente trabalho teve como objetivo definir o tipo de substrato, a temperatura, o tempo médio e a frequência relativa de germinação, para auxiliar a condução de testes de germinação e vigor em sementes de Mimosa caesalpiniaefolia. Para tanto, realizou-se um experimento no Laboratório de Análise de Sementes do CCA-UFPB, em Areia-PB, em delineamento inteiramente casualizado com os tratamentos distribuídos em esquema fatorial 4x4, com os fatores temperaturas (20, 25, 30ºC constantes e 20-30ºC alternadas) e substratos (entre papel, sobre papel, entre areia e entre vermiculita), em quatro repetições de 25 sementes. Foram analisados os seguintes parâmetros: porcentagem de germinação e de plântulas anormais, primeira contagem da germinação e velocidade de germinação, tempo médio e frequência relativa de germinação, massa fresca e massa seca de plântulas. A temperatura de 25ºC mostrou-se mais adequada para a condução dos testes de germinação e vigor em sementes de Mimosa caesalpiniaefolia, independentemente do substrato utilizado. O substrato entre papel foi o mais apropriado para avaliação da qualidade fisiológica das sementes e a sincronização do processo germinativo foi maior no substrato entre papel, independentemente da temperatura empregada.
