ABSTRACT Objective To describe and compare the clinical characteristics and outcomes of patients admitted to intensive care units during the first and second waves of the COVID-19 pandemic. Methods In this retrospective single-center cohort study, data were retrieved from the Epimed Monitor System; all adult patients admitted to the intensive care unit between March 4, 2020, and October 1, 2021, were included in the study. We compared the clinical characteristics and outcomes of patients admitted to the intensive care unit of a quaternary private hospital in São Paulo, Brazil, during the first (May 1, 2020, to August 31, 2020) and second (March 1, 2021, to June 30, 2021) waves of the COVID-19 pandemic. Results In total, 1,427 patients with COVID-19 were admitted to the intensive care unit during the first (421 patients) and second (1,006 patients) waves. Compared with the first wave group [median (IQR)], the second wave group was younger [57 (46-70) versus 67 (52-80) years; p<0.001], had a lower SAPS 3 Score [45 (42-52) versus 49 (43-57); p<0.001], lower SOFA Score on intensive care unit admission [3 (1-6) versus 4 (2-6); p=0.018], lower Charlson Comorbidity Index [0 (0-1) versus 1 (0-2); p<0.001], and were less frequently frail (10.4% versus 18.1%; p<0.001). The second wave group used more noninvasive ventilation (81.3% versus 53.4%; p<0.001) and high-flow nasal cannula (63.2% versus 23.0%; p<0.001) during their intensive care unit stay. The intensive care unit (11.3% versus 10.5%; p=0.696) and in-hospital mortality (12.3% versus 12.1%; p=0.998) rates did not differ between both waves. Conclusion In the first and second waves, patients with severe COVID-19 exhibited similar mortality rates and need for invasive organ support, despite the second wave group being younger and less severely ill at the time of intensive care unit admission.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID-19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p<0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p<0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

Abstract: En | Text: En | PDF: En

Diabetes Mellitus (DM) is a metabolic syndrome characterized by hyperglycemia. Chronic complications affect a number of organs, including the lungs. Cissampelos sympodialis Eichl (Menispermaceae) is a plant used to treat respiratory diseases. The aim of this study was to evaluate the effect of Cissampelos sympodialis extract (CSE) in lungs of diabetic rats. We used 30 Wistar rats divided into three groups: control group (CG), diabetic group (DG) and diabetic Cissampelos sympodialis treatment group (DTG). Diabetes was induced by streptozotocin (40 mg/kg i.v.). The CSE (400 mg/kg, po) was administered daily, during four weeks, beginning one week after the onset of DM. The treatment with CSE was not able to reduce blood glucose levels after streptozotocin injection. However, it was able to decrease cholesterol and triglycerides and prevent damage on pancreatic islets morphology. Additionally, morphological alterations such as alveolar septa loss, inflammatory infiltrate and fibrosis were seen in lung tissue of rats with DM, and treatment with CSE apparently reversed these histopathological findings. Thus, CSE treatment reduced the lipid profile and restored the lung architecture of diabetic animals by a mechanism independent of glycemia and which might be associated with the reduction of the damage on the pancreatic islets.

OBJECTIVES: To assess the outcomes of pediatric patients with laboratory-confirmed coronavirus disease (COVID-19) with or without multisystem inflammatory syndrome in children (MIS-C). METHODS: This cross-sectional study included 471 samples collected from 371 patients (age<18 years) suspected of having severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study group comprised 66/371 (18%) laboratory-confirmed pediatric COVID-19 patients: 61 (92.5%) patients tested positive on real-time reverse transcription-polymerase chain reaction tests for SARS-CoV-2, and 5 (7.5%) patients tested positive on serological tests. MIS-C was diagnosed according to the criteria of the Center for Disease Control. RESULTS: MIS-C was diagnosed in 6/66 (9%) patients. The frequencies of diarrhea, vomiting, and/or abdominal pain (67% vs. 22%, p=0.034); pediatric SARS (67% vs. 13%, p=0.008); hypoxemia (83% vs. 23%, p=0.006); and arterial hypotension (50% vs. 3%, p=0.004) were significantly higher in patients with MIS-C than in those without MIS-C. The frequencies of C-reactive protein levels >50 mg/L (83% vs. 25%, p=0.008) and D-dimer levels >1000 ng/mL (100% vs. 40%, p=0.007) and the median D-dimer, troponin T, and ferritin levels (p<0.05) were significantly higher in patients with MIS-C. The frequencies of pediatric intensive care unit admission (100% vs. 60%, p=0.003), mechanical ventilation (83% vs. 7%, p<0.001), vasoactive agent use (83% vs. 3%, p<0.001), shock (83% vs. 5%, p<0.001), cardiac abnormalities (100% vs. 2%, p<0.001), and death (67% vs. 3%, p<0.001) were also significantly higher in patients with MIS-C. Similarly, the frequencies of oxygen therapy (100% vs. 33%, p=0.003), intravenous immunoglobulin therapy (67% vs. 2%, p<0.001), aspirin therapy (50% vs. 0%, p<0.001), and current acute renal replacement therapy (50% vs. 2%, p=0.002) were also significantly higher in patients with MIS-C. Logistic regression analysis showed that the presence of MIS-C was significantly associated with gastrointestinal manifestations [odds ratio (OR)=10.98; 95%CI (95% confidence interval)=1.20-100.86; p=0.034] and hypoxemia [OR=16.85; 95%CI=1.34-211.80; p=0.029]. Further univariate analysis showed a positive association between MIS-C and death [OR=58.00; 95%CI=6.39-526.79; p<0.0001]. CONCLUSIONS: Pediatric patients with laboratory-confirmed COVID-19 with MIS-C had a severe clinical spectrum with a high mortality rate. Our study emphasizes the importance of investigating MIS-C in pediatric patients with COVID-19 presenting with gastrointestinal involvement and hypoxemia.

Objetivou-se avaliar características morfológicas de clones de Panicum maximum durante o período de rebrota após a interrupção da irrigação. Os clones de Panicum foram coletados em Sergipe e em três locais de Pernambuco ("São Bento do Una", "Itambé" e "São João da Coroa Grande"), além das cultivares 'Mombaça', 'Tanzânia' e 'Massai'. Os tratamentos consistiram de sete clones submetidos a 7, 14, 21 ou 28 dias de suspensão da irrigação. O delineamento utilizado foi o inteiramente casualizado em arranjo fatorial 7 × 4 com quatro repetições. Foram avaliados o número de perfilhos, altura da planta, comprimento da lâmina foliar, número de folhas verdes por perfilho e número de folhas mortas por perfilho. O fator clone afetou significativamente o número de perfilhos por vaso e o número de folhas mortas por perfilho (P≤0,05). O clone de Sergipe produziu mais perfilhos (8.39) que os demais após 28 dias de interrupção da irrigação, enquanto a cultivar 'Mombaça' apresentou mais folhas mortas (5.39) após 7 dias sem irrigação. Em geral, a interrupção da irrigação por 28 dias resultou em plantas mais altas com lâminas foliares maiores e com número superior de folhas verdes por perfilho.

This study aimed to evaluate the morphological characteristics of Panicum maximum clones during the regrowth period following cessation of irrigation. Panicum clones were collected in Sergipe and in three Pernambuco locations (‘São Bento do Una’, ‘Itambé’ and ‘São João da Coroa Grande’), in addition to ‘Mombaça’, ‘Tanzânia’ and ‘Massai’ cultivars. The treatments consisted of seven clones, which were subjected to either 7, 14, 21 or 28 days of water suspension. The experimental design was completely randomized in a factorial 7 × 4 design, with four replicates. The morphological characteristics evaluated included the number of tillers, plant height, leaf blade length, number of green leaves per tiller and number of dead leaves per tiller. The clone factor significantly affected the number of tillers per pot and the number of dead leaves per tiller (P ≤ 0.05). The clone from Sergipe produced a greater number of tillers (8.39) than the other clones following 28 days of water suspension, while the ‘Mombaça’ cultivar had a greater number of dead leaves (5.39) after 7 days of water suspension. In general, the 28-day cessation of irrigation period resulted in taller plants with larger leaf blades and a greater number of green leaves per tiller.

RESUMO Introdução: A atividade física deve ser parte fundamental de programas de promoção da saúde. No entanto, sua realização pode expor o indivíduo a riscos de lesão, o que torna necessária a adoção de medidas preventivas como o aquecimento, com o intuito de minimizar os riscos e/ou contribuir para o melhor desempenho funcional. Objetivo: O propósito deste estudo foi analisar o efeito agudo de diferentes tempos de aquecimento sobre flexibilidade, equilíbrio e desempenho funcional em indivíduos fisicamente ativos. Método: Trinta e dois homens saudáveis que realizavam exercício regularmente pelo menos três vezes por semana foram aleatoriamente incluídos em um de quatro grupos (n = 8): G0 (sem aquecimento), G5 (aquecimento por cinco min.), G10 (aquecimento por dez min.) e G15 (aquecimento por quinze min.). Os indivíduos foram avaliados antes e depois da intervenção nas seguintes variáveis: flexibilidade do reto femoral (RF) e dos isquiotibiais (IT), equilíbrio corporal com olhos abertos e fechados e desempenho funcional por meio dos testes de salto triplo horizontal (STH) e shuttle run (SR). O aquecimento foi realizado numa esteira ergométrica entre 70% e 80% da frequência cardíaca máxima estimada para idade. Resultado: Não houve diferenças significativas na flexibilidade e no equilíbrio nas comparações intra e intergrupos (p > 0,05). Contudo, houve melhora significativa do desempenho funcional somente no G10 na comparação intragrupo para as variáveis STH (de 5,88 ± 0,55 para 6,23 ± 0,66; p = 0,0051) e SR (de 4,72 ± 0,13 para 4,61 ± 0,13; p= 0,0194). Conclusão: O aquecimento durante 10 minutos parece melhorar o desempenho funcional em indivíduos ativos, podendo também ser uma alternativa viável para a prevenção de lesão.

ABSTRACT Introduction: Physical activity should be a fundamental part of health promotion programs. However, its performance can expose the individual to risk of injury, which makes it necessary to adopt preventive measures such as warm-up (WU) in order to minimize risks and/or contribute to better functional performance. Objective: The purpose of this study was to analyze the acute effect of different warm-up times on flexibility, balance, and functional performance in physically active individuals. Method: Thirty two healthy men, who exercise regularly at least three times a week, were randomly assigned to one of four groups (n=8): G0 (without WU), G5 (WU for 5 min), G10 (WU for 10 min), and G15 (WU for 15 min). The subjects were assessed before and after the intervention on the following variables: flexibility of the rectus femoris (RF) and hamstrings (HM) muscles, body balance with open and close eyes and functional performance through triple horizontal jump (THJ) and shuttle run (SR) tests. The WU was carried out on a treadmill between 70% and 80% estimated maximum heart rate for age. Results: There were no significant differences in flexibility and balance in intra and intergroup comparisons (p>0.05). However, there was a significant improvement in functional performance only in G10 in the intragroup comparison for THJ variables (5.88±0.55 to 6.23±0.66; p=0.0051) and SR variables (4.72±0.13 to 4.61±0.13; p=0.0194) variables. Conclusion: Warm-up for 10 minutes seems to improve functional performance in active individuals, and may be a viable alternative for injury preventions.

RESUMEN Introducción: La actividad física debe ser parte fundamental de los programas de promoción de la salud. Sin embargo, su realización puede exponer al individuo a riesgos de lesión, lo que hace necesaria la adopción de medidas preventivas como el calentamiento con el fin de minimizar los riesgos y/o contribuir para el mejor desempeño funcional. Objetivo: El propósito de este estudio fue analizar el efecto agudo de diferentes tiempos de calentamiento sobre flexibilidad, equilibrio y desempeño funcional en individuos físicamente activos. Método: Treinta y dos hombres sanos que hacen ejercicio regularmente por lo menos tres veces por semana fueron incluidos aleatoriamente en uno de cuatro grupos (n = 8): G0 (sin calentamiento), G5 (calentamiento por cinco minutos), G10 (calentamiento por diez minutos) y G15 (calentamiento por quince minutos). Los individuos fueron evaluados antes y después de la intervención en las siguientes variables: flexibilidad del recto femoral (RF) y de los isquiotibiales (IT), equilibrio corporal con ojos abiertos y cerrados y desempeño funcional por medio de las pruebas de salto triple horizontal (STH) y shuttle run (SR). El calentamiento se realizó en una cinta rodante entre el 70% y el 80% de la frecuencia cardiaca máxima estimada para la edad. Resultado: No hubo diferencias significativas en la flexibilidad y el equilibrio en las comparaciones intra e intergrupos (p > 0,05). Sin embargo, hubo una mejora significativa en el desempeño funcional sólo en el G10 en la comparación intragrupo para las variables STH (de 5,88 ± 0,55 a 6,23 ± 0,66, p = 0,0051) y SR (de 4,72 ± 0,13 a 4,61 ± 0,13, p = 0,0194). Conclusión : El calentamiento durante 10 minutos parece mejorar el desempeño funcional en individuos activos, pudiendo también ser una alternativa viable para la prevención de lesión.

Foram testados os efeitos de dois intervalos de descanso entre pastoreios, 375 e 750 graus-dia, baseado na soma térmica para a expansão foliar de gramíneas nativas de dois grupos funcionais sobre o comportamento ingestivo de novilhas de corte. O delineamento foi em blocos ao acaso, com dois tratamentos, três repetições de área e medidas repetidas no tempo. Foram realizadas três avaliações (nov/11, jan e mar/12), com 24h cada, utilizando novilhas de corte com 12 meses. Estimou-se o consumo de forragem com marcador externo (Cr2O3). A massa de lâminas foliares foi semelhante entre os tratamentos, apresentando média de 1261kg MS ha-1. O tempo médio dispendido pelos animais em pastejo foi de 627,4 minutos e a taxa de bocados média foi de 37,1 bocados minuto-1. O número médio de refeições foi de 5,9 refeições dia-1, com uma média de 118,5 minutos por refeição. Os animais visitaram, em média, 6,1 estações alimentares por minuto e permaneceram nessas estações por 12 segundos. Houve diferença no tempo de pastejo e taxa de bocado nos períodos, com uma redução ao longo do tempo. Os intervalos de descanso testados provaram ter pouco efeito no comportamento ingestivo e no consumo de forragem das novilhas

It was evaluated the effect of two rest intervals between grazing occupations in rotational grazing; 375 and 750 DD (degree-days); based on the cumulative thermal sum necessary for leaf expansion of native grasses of two functional groups over the grazing behavior variables from beef heifers with 12 months old. The experiment was conducted as a completely randomized block design, with two treatments, three replications and measures repeated over time. Grazing behavior was assessed in three occasions (Nov 2011, Jan and Mar 2012), with 24h each. The herbage intake was estimated using an external marker (Cr2O3). The leaf mass was similar among the rest intervals, with a mean of 1261kg DM ha-1. The average grazing time was 627.4min day-1 and bite rate was 37.1 bites min-1. The average number of daily meals was 5.9 with an average of 118.5 minutes. Number of feeding stations visited per minute was 6.1 and the feeding stations permanence time was of 12 seconds. There was a reduction only on grazing time and bite rate over the periods. The range of thermal sums evaluated to define the rest intervals in rotational grazing proved no effect on heifers' grazing behavior and herbage intake

A presente pesquisa teve por objetivo adaptar o Questionário Sentido de Vida (QSV), reunindo evidências de sua validade fatorial e consistência interna. Realizaram-se dois estudos junto a estudantes universitários de João Pessoa, PB. No estudo 1 participaram 414 voluntários, a maioria do sexo feminino (63,5%), com idade média de 28,2 anos (dp = 9,50). No estudo 2 participaram 201 pessoas, a maioria do sexo feminino (74,6%), com idade média de 26,7 anos (dp = 9,56). Nos dois estudos os participantes responderam o QSV e perguntas demográficas, sendo que os do segundo responderam dois outros instrumentos: Teste Propósito de Vida (Pil-Teste) e Escala de Percepção Ontológica do Tempo (EPOT). No estudo 1 foi realizada uma análise fatorial confirmatória, sugerindo a adequação da estrutura bifatorial [GFI = 0,94, AGFI = 0,90, CFI = 0,95 e RMSEA = 0,086]; os alfas de Cronbach dos fatores foram 0,89 (busca de sentido) e 0,85 (presença de sentido). No estudo 2 foi observada evidência de validade convergente do QSV com o Pil-Teste e a EPOT. Concluiu-se que o QSV tem demonstrado ser pertinente para avaliar, nos modos propostos, o sentido de vida, podendo ser utilizado em pesquisas no contexto brasileiro.

This research aimed to adapt the Meaning in Life Questionnaire (MLQ) gathering evidence of its factorial validity and reliability. Two studies were held with undergraduate students from Joao Pessoa, Paraiba state, Brazil. In Study 1, participants were 414 volunteers, mostly female (63.5%), with a mean age of 28.2 (sd = 9.56). Study 2 involved 201 subjects, mostly female (74.6%), with a mean age of 26.7 (sd = 9.50). The participants of both studies answered the MLQ and demographic questions. The participants of Study 2 also answered the following instruments: Purpose of Life Test (Pil-Test) and Ontological Time PerceptionScale (OTPS). In Study 1, a confirmatory factor analysis was performed, suggesting the appropriateness of the two-factor structure [GFI = .94, AGFI = .90, CFI = .95, and RMSEA = 0.086]; the Cronbach's alphas of these factors were .89 (search for meaning) and .85 (presence of sense). In Study 2, we observed evidence of convergent validity of the MLQ with respect to the Pil-Test and OTPS. In conclusion, the MLQ was considered an appropriate instrument to measure the life purpose in the way it was proposed, being useful in research in the Brazilian context.

A utilização de cobertura do solo nos parreirais é uma prática conservacionista utilizada para diminuir a erosão e melhorar a qualidade física do solo. O objetivo deste estudo foi avaliar espécies de plantas de cobertura e sistemas de manejo da cobertura sobre as propriedades físicas do solo e sobre o rendimento de uva. O experimento foi conduzido em Bento Gonçalves, RS, sobre um Cambissolo Háplico, num parreiral implantado em 1989, com os cultivares Niágara Branca e Niágara Rosada no sistema de latada. Os tratamentos, estabelecidos em 2002, foram três coberturas vegetais: vegetação espontânea (SS), aveia-preta (Avena strigosa Schreb) (BO) e consórcio de trevo branco (Trifolium repens L.) + trevo vermelho (Trifolium pratense L.) + azevém (Lolium multiflorum L.) (MC). Dois sistemas de manejo foram utilizados: dessecado com herbicida (D) e roçada mecânica (M). O solo em uma área de floresta nativa foi coletado como condição de referência. O delineamento experimental foi de blocos ao acaso com três repetições. As propriedades físicas nas linhas do parreiral não diferiram estatisticamente entre as coberturas avaliadas e foram similares à floresta nativa, demonstrando boa qualidade estrutural. Entretanto, nas entrelinhas, ocorreram redução de bioporos, macroporosidade, porosidade total e aumento na densidade do solo, em razão da compactação da camada superficial do solo. O sistema de manejo da cobertura pela roçada teve maior estabilidade dos agregados do que o manejo dessecado. Os tratamentos influenciaram o rendimento da videira em anos, com excesso ou distribuição irregular de chuvas.

The use of cover crops in vineyards is a conservation practice with the purpose of reducing soil erosion and improving the soil physical quality. The objective of this study was to evaluate cover crop species and management systems on soil physical properties and grape yield. The experiment was carried out in Bento Gonçalves, RS, Southern Brazil, on a Haplic Cambisol, in a vineyard established in 1989, using White and Rose Niagara grape (Vitis labrusca L.) in a horizontal, overhead trellis system. The treatments were established in 2002, consisting of three cover crops: spontaneous species (SS), black oat (Avena strigosa Schreb) (BO), and a mixture of white clover (Trifolium repens L.), red clover (Trifolium pratense L.) and annual rye-grass (Lolium multiflorum L.) (MC). Two management systems were applied: desiccation with herbicide (D) and mechanical mowing (M). Soil under a native forest (NF) area was collected as a reference. The experimental design consisted of completely randomized blocks, with three replications. The soil physical properties in the vine rows were not influenced by cover crops and were similar to the native forest, with good quality of the soil structure. In the inter-rows, however, there was a reduction in biopores, macroporosity, total porosity and an increase in soil density, related to the compaction of the surface soil layer. The M system increased soil aggregate stability compared to the D system. The treatments affected grapevine yield only in years with excess or irregular rainfall.

CONTEXTO: O Teste de Atitudes Alimentares é o instrumento mais utilizado para avaliar distúrbios alimentares em adultos e adolescentes em uma variedade de culturas e amostras. OBJETIVO: O objetivo deste estudo foi avaliar as propriedades psicométricas da versão portuguesa da Escala de Atitudes Alimentares para Crianças (ChEAT). MÉ;TODO: Novecentos e cinquenta e seis alunos do ensino secundário (565 moças e 391 moços) responderam ao ChEAT. O cálculo da fidelidade teste-reteste foi feito por meio das respostas de 206 participantes da amostra total que voltaram a responder ao questionário após quatro a seis semanas. As análises psicométricas foram realizadas para o total da amostra e para ambos os sexos separadamente. RESULTADOS: A consistência interna e a fidelidade teste-reteste foram satisfatórias. A análise fatorial em componentes na amostra total resultou em quatro fatores que explicam 42,35% da variância total. A composição dos fatores foi semelhante na amostra total e em ambos os sexos. Os fatores denominaram-se: F1 "Medo de Engordar"; F2 "Comportamentos Restritivos e Purgativos"; F3 "Preocupação com a Comida" e F4 "Pressão Social para Comer". A validade concorrente foi explorada com a Escala de Silhuetas Corporais (CDFRS) e foi elevada. CONCLUSÃO: A versão portuguesa do ChEAT é um instrumento útil e válido para a avaliação de atitudes e comportamentos alimentares em adolescentes portugueses.

BACKGROUND: The Eating Attitudes Test (EAT) is the most widely used instrument for evaluating eating disorders in adults and adolescents in a variety of cultures and samples. OBJECTIVE: The aim of this study was to analyse the psychometric properties of the Portuguese version of the Children's Eating Attitudes Test (ChEAT). METHOD: Nine hundred and fifty-six Portuguese secondary students (565 girls and 391 boys) answered the ChEAT. The test-retest reliability was obtained with data from 206 participants from the total sample who re-answered the questionnaire after 4-6 weeks. Psychometric analyses were carried out for the total sample and separately for girls and boys. RESULTS: Internal consistency and test-retest reliability were satisfactory. Principal components factorial analysis yielded four factors in the total sample, accounting for 42.35% of the total variance. Factor structure was similar in the total sample and in both genders. Factors were labelled: F1 "Fear of Getting Fat", F2 "Restrictive and Purgative Behaviours", F3 "Food Preoccupation" and F4 "Social Pressure to Eat". The concurrent validity, explored using the Contour Drawing Figure Rating Scale (CDRS) was high. DISCUSSION: The Portuguese version of the ChEAT is a valid and useful instrument for the evaluation of abnormal eating attitudes and behaviours among Portuguese adolescents.

O manejo do solo pode interferir na disponibilidade de nutrientes e na produtividade de frutos. O objetivo deste estudo foi avaliar o efeito de formas de manejo da fitomassa de diferentes espécies de plantas de cobertura verde sobre características químicas do solo, relacionadas à matéria orgânica e à disponibilidade de nutrientes, e sobre a produtividade de uva. O experimento foi realizado na Embrapa Uva e Vinho, em Bento Gonçalves, RS, sobre um Cambissolo Háplico, num parreiral implantado em 1989, com os cultivares Niágara Branca e Niágara Rosada, no sistema de latada. Os tratamentos testados foram implantados em 2002 e consistiram em três coberturas vegetais: vegetação espontânea, aveia-preta e consórcio de trevo-branco + trevo-vermelho + azevém; e dois sistemas de manejo: dessecado com herbicida e roçado, os quais foram realizados no outono, previamente à ressemeadura das espécies. O delineamento experimental foi de blocos ao acaso com três repetições. Os atributos químicos indicadores da acidez e da disponibilidade de nutrientes no solo foram pouco influenciados pelas espécies de cobertura. A dessecação das plantas aumentou os teores de Ca e Mg trocáveis, P disponível e C orgânico total em relação ao manejo roçado. A produtividade de uva nas safras de 2004 e 2006 foi baixa em relação ao potencial dos cultivares, possivelmente por restrições climáticas, contudo foi maior quando se utilizou a aveia como planta de cobertura do que com o consórcio de plantas.

Soil management can have effects on nutrient availability and fruit yield. The objective of this study was to evaluate the effect of phytomass management forms of different cover crop species on soil chemical properties related to organic matter, nutrient availability, and on grapevine yields. The experiment was carried out in Embrapa Uva e Vinho, in Bento Gonçalves, RS, in Southern Brazil, on a Haplic Cambissol, in a vineyard established in 1989, using White and Rose Niagara grape in a horizontal overhead trelling system. The treatments established in 2002 were three cover crops: spontaneous native species, black oat (Avena strigosa), and a mixture of white clover (Trifolium repens) + red clover (Trifolium pratense) + annual ryegrass (Lolium multiflorum); and two management systems: desiccation by herbicide spraying and mechanical mowing, performed each autumn prior to cover crop resowing. The experiment had a completely randomized block design, with three replications. Soil acidity and nutrient contents were little influenced by the plant cover. In comparison with the mowed management, herbicide application increased exchangeable Ca and Mg, extracted P, and organic C levels in the soil. The grape yield in the seasons 2004 and 2006 was low in view to the cultivar potential, probably affect by climatic limitations, but was higher when black oat was used as plant cover instead of the mixture of plant covers.

Melipona fasciculata Smith é uma abelha nativa, social e sem ferrão que produz cera, mel e geoprópolis. O presente trabalho objetivou caracterizar, do ponto de vista farmacognóstico, o geoprópolis de Melipona fasciculata, coletado em meliponários nos municípios de Arari, São Bento e São João Batista, da Baixada maranhense, no Estado do Maranhão, visando estabelecer dados para o controle de qualidade e padronização do produto. A metodologia utilizada constou de análises sensoriais, abordagem química, perfis cromatográficos e determinação dos teores de flavonóides. Os resultados demonstram que o geoprópolis apresenta características sensoriais similares às encontradas para própolis de Apis mellifera, presença de compostos fenólicos em maior concentração, além de substâncias da classe dos terpenos e saponinas e ausência de alcalóides. Os perfis cromatográficos indicaram que a composição e concentração das substâncias químicas são diferentes entre as amostras. Os teores de flavonóides variaram de 0,17 - 2,6%, os quais para a maioria das amostras apresentaram valores acima do mínimo exigido pela legislação brasileira para própolis de Apis mellifera. Os dados encontrados sugerem que as variações qualitativa e quantitativa de flavonóides e outros constituintes químicos no geoprópolis são fortemente afetados pela flora visitada pelas abelhas, região geográfica e fatores ambientais.

Melipona fasciculata Smith is a native, social, stingless bee species that produces wax, honey and geopropolis. This work aimed to do a pharmacological evaluation of Melipona fasciculata geopropolis, collected in beehives in the municipal districts of Arari, São Bento and São João Batista, in Baixada maranhense, in the state of Maranhão, Brazil, seeking to obtain basis for the quality control and standardization of the product. The methodology used included the accomplishment of sensorial analyses, chemical approach, chromatographic profiles and determination of the flavonoids contents. The results demonstrate that the geopropolis have organoleptic characteristics similar to the ones found for the propolis of Apis mellifera, presence of phenolic compounds in larger concentration, besides substances of the class of the terpenes and saponins and absence of alkaloids. The chromatographic profiles indicated that the composition and concentration of the chemical substances are different among the samples. The flavonoids contents ranged between 0.17 - 2.6%. The content for most of the samples presented values above the minimum demanded by the Brazilian legislation for propolis of Apis mellifera. The found data suggest that the qualitative and quantitative variations of flavonoids and other chemical substances in geopropolis are strongly affected for the flora visited by the bees, geographical area and environmental factors.
