Abstract Objective To analyze the impact of the COVID-19 pandemic on the residency of gynecology and obstetrics in São Paulo. Methods Cross-sectional study developed by representatives of residents of the Association of Gynecology and Obstetrics of the State of São Paulo (SOGESP, in the Portuguese acronym). Data were collected from questionnaires applied to gynecology and obstetrics residents registered on the SOGESP website in February 2022. The interviewees answered about the repercussions of the pandemic on medical residency and whether they had technical and psychological support during the period. Results A total of 247 questionnaires were collected from residents of gynecology and obstetrics. The residents had an age of 28.3 ± 3 years old, and most of them were female (88.4%). The displacement to COVID care was reported by 62.34% of the students, but only 35.6% reported completely adequate personal protective equipment and only 7.7% reported complete theoretical and technical instruction to support these patients. Almost all of the interviewees stated that the gynecology sector was the most affected. The majority of the interviewees considered that the second-year residents had the greatest loss, and more than half of the residents in the 1st and 2nd year said they wished to give up their residency during the pandemic. More than 80% of the residents reported online theoretical classes and/or presentation of articles, reinforcing the fact that virtual activities gained a greater space within the medical residency. Conclusion The pandemic impacted the residency in greater proportion in outpatient clinics and gynecological surgeries, also interfering with the physician's desire to continue with the program.
Resumo Objetivo Analisar o impacto pandemia de COVID-19 sobre a residência de ginecologia e obstetrícia do Estado de São Paulo. Métodos Estudo transversal desenvolvido por representantes dos residentes da Associação de Ginecologia e Obstetrícia do Estado de São Paulo (SOGESP). Foram coletados dados de questionários aplicados aos residentes de ginecologia e obstetrícia cadastrados no site da SOGESP em fevereiro de 2022. Os entrevistados responderam sobre repercussões da pandemia sobre a residência médica e se tiveram suporte técnico e psicológico durante o período. Resultados Foram levantados 247 questionários de residentes de ginecologia e obstetrícia. Os residentes apresentaram idade de 28,3 ± 3 anos, sendo a maioria do sexo feminino (88,4%). O deslocamento para “covidários” foi referido por 62,34% dos avaliados, porém somente 35,6% referiram equipamento de proteção individual completamente adequado e apenas 7,7% referiram instrução completa teórica e técnica para o suporte destes pacientes. Quase a totalidade dos entrevistados afirmou que o setor de ginecologia foi o mais afetado. A maioria dos entrevistados considerou que o os residentes do segundo ano foram os que tiveram maior prejuízo, sendo que mais da metade dos residentes do 1° e 2° ano afirmou ter desejado desistir da residência durante a pandemia. Mais de 80% dos residentes referiram aulas teóricas e/ou apresentação de artigos online, reforçando o fato de que as atividades virtuais ganharam um espaço maior dentro da residência médica. Conclusão A pandemia impactou nas residências em maior proporção nos ambulatórios e cirurgias ginecológicas, interferindo também sobre o desejo do médico de seguir com o programa.

RESUMO: Realizou-se este estudo com o objetivo de avaliar níveis de energia líquida (EL), mantendo a relação caloria: nutriente, no desempenho e características de carcaça de suínos dos 30 aos 70 kg. Foram utilizados 60 suínos machos castrados, com pesos iniciais de 31,94 ± 3,54 kg e finais de 71,98 ± 5,99 kg. Os animais foram distribuídos em delineamento experimental de blocos casualizados, em cinco níveis de EL (2,40; 2,45; 2,50; 2,55; 2,60 Mcal de EL kg-1 de dieta), com seis repetições e dois animais por unidade experimental. O período experimental foi dividido em fase I: 30 aos 50 kg e fase II: 50 aos 70 kg. As variáveis analisadas foram os consumos de ração diária (CRD), energia líquida (CEL) e lisina digestível (CLdig), ganho de peso diário (GPD), conversão alimentar (CA), peso final (PF), conversão de lisina digestível: ganho (CLdig:G), custo: ganho (C:G), área de olho de lombo (AOL), profundidade de músculo (PM), espessura de toucinho da primeira camada (ET1), espessura de toucinho da segunda camada (ET2), espessura de toucinho total (ETt), percentual de carne magra (CM) e o índice de bonificação de carcaça (IB). Dos 30 aos 50 kg, verificou-se aumento linear (P < 0,05) do PF, GPD e dos CEL e CLdig com o aumento dos níveis de EL na dieta. Dos 50 aos 70 kg, o aumento dos níveis de EL na dieta promoveu melhora linear (P < 0,05) do PF, GPD, CEL, CLdig e da CA dos suínos. No período total, verificou-se aumento linear (P < 0,05) do GPD, CEL, CLdig e melhora linear (P < 0,05) da CA de acordo com o aumento do nível de EL na dieta. As demais variáveis de desempenho não foram afetadas (P > 0,05) pelos níveis de EL. Verificou-se aumento (P < 0,05) da ET2 de acordo com o aumento do nível de EL, porém sem alterar (P > 0,05) as demais características de carcaça. Recomenda-se o nível 2,60 Mcal de EL kg-1 de dieta para suínos machos castrados dos 30 aos 70 kg.
ABSTRACT: This study evaluated the effect of dietary net energy (NE) levels on growth performance and carcass characteristics of barrows from 30 to 70 kg of body weight (BW). Sixty barrows with initial body weight (IBW) of 31.94 ± 3.54 kg and final body weight (FBW) of 71.98 ± 5.99 kg were allotted to one of five dietary NE levels (2.40, 2.45, 2.50, 2.55, and 2.60 Mcal kg-1), using a completely randomized block design with six replicates and two barrows per replicate. The experimental period was divided into phase I: 30 to 50 kg and phase II: 50 to 70 kg. The variables analyzed were average daily feed intake (ADFI), net energy intake (NEI), digestible lysine intake (LysI), average daily gain (ADG), feed conversion (FC), FBW, digestible lysine conversion:gain (LysI:G), Cost:Gain (C:G), loin eye area (LEA), muscle depth (MD), first backfat layer (BF1), second backfat layer (BF2), total backfat (BFt), lean meat percentage, and carcass bonus index (BI). In phase I, there was a linear increase (P < 0.05) in FBW, ADG, NEI, and LysI with increasing NE levels in the diet. In phase II, increasing dietary NE levels also increased (P < 0.05) FBW, ADG, NEI, LysI, and FC linearly. Overall, there was a linear increase (P < 0.05) in ADG, NEI, LysI, and FC with increasing NE levels in the diet. The other performance variables were not affected (P > 0.05) by the NE levels. There was an increase (P < 0.05) in BF2 with increasing NE levels, but the other carcass characteristics were not altered (P > 0.05). We recommended 2.60 Mcal of NE kg-1 in the diet for growing barrows from 30 to 70 kg.

ABSTRACT Coleoptera order in Brazil presents 105 families with approximately 28,000 species. The life cycle and diversity of Coleoptera are strongly influenced by climate and vegetation. The objective of this study was to evaluate the seasonality and distribution of Coleoptera families in an area of the Cerrado in the Federal District (DF) of Brazil. The insects were collected monthly, between June 2015 and May 2016, using a light trap activated only in nights with a new moon, in an area of cerrado sensu stricto in Planaltina/DF, Brazil. The data were correlated with climatic variables. A total of 21,100 Coleoptera specimens belonging to 34 families were collected, with Melolonthidae (n = 11,075), Carabidae (n = 2,522), Scarabaeidae (n = 2,506), Bostrichidae (n = 1,196), and Chrysomelidae (n = 1,086) being the most abundant. Coleoptera were significantly more abundant in the first half of the rainy season. There was a significant and positive correlation between the abundance of Coleoptera and the climatic variables temperature and precipitation. The data presented in this study are related to an atypical year under the strong influence of the El Niño phenomenon, which may influence the abundance of Coleoptera. Circular analysis revealed that Coleoptera, and the most abundant families, presented seasonality throughout the year with a grouped distribution at the beginning of the rainy season (October to December). This study demonstrates that the richness and abundance of the Coleoptera order, in the Cerrado, is strongly influenced by the characteristic climatic seasons of the biome.

RESUMO O manejo farmacológico da asma mudou consideravelmente nas últimas décadas, com base no entendimento de que a asma é uma doença heterogênea e complexa, com diferentes fenótipos e endótipos. Agora está claro que o objetivo do tratamento da asma deve ser alcançar e manter o controle da doença e evitar riscos futuros (exacerbações, instabilidade da doença, perda acelerada da função pulmonar e efeitos adversos do tratamento). Isso implica em uma abordagem personalizada, incluindo tratamento farmacológico, educação do paciente, plano de ação por escrito, treinamento para uso do dispositivo inalatório e revisão da técnica inalatória a cada visita ao consultório. Um painel de 22 pneumologistas brasileiros foi convidado a revisar criticamente evidências recentes de tratamento farmacológico da asma e a preparar esta recomendação, um guia de tratamento adaptado à nossa realidade. A escolha dos tópicos ou questões relacionadas às mudanças mais significativas nos conceitos e, consequentemente, no manejo da asma na prática clínica foi realizada por um painel de especialistas. Foi solicitado a cada especialista que revisasse criticamente um tópico ou respondesse a uma pergunta, com base em evidências, para estas recomendações. Numa segunda fase, três especialistas discutiram e estruturaram todos os textos submetidos pelos demais e, na última fase, todos revisaram e discutiram cada recomendação. As presentes recomendações se aplicam a adultos e crianças com asma e destinam-se a médicos envolvidos no tratamento da doença.
ABSTRACT The pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.

Resumo Fundamento: O rastreamento genético em cascata é o método mais economicamente viável para a identificação de indivíduos com hipercolesterolemia familiar, mas as melhores estratégias para o recrutamento de indivíduos em risco em um programa de rastreamento deste tipo não são inteiramente conhecidas. Objetivo: Identificar os melhores preditores de recrutamento familiar em rastreamento genético, usando características derivadas de probandos testados. Métodos: Foram inscritos 183 casos índices com resultado genético positivo, que tiveram familiares rastreados de janeiro de 2011 a julho de 2015. A variável de resposta foi o número de familiares para cada caso índice inscrito. Todas as variáveis do estudo foram baseadas em características clínicas e socioeconômicas derivadas dos casos índices. O tamanho do efeito das variáveis preditoras foi obtido de modelo linear geral utilizando função de associação de regressão binomial negativa. A significância foi considerada com p < 0,05. Resultados: A média de idade dos casos índices ao ingressar no programa foi de 50 anos; 78,1% dos indivíduos relataram conhecimento de familiares com dislipidemia. O nível médio de LDL-colesterol inicial foi de 316 ± 90 mg/dL. Origem de referência por meio do site do programa em cascata vs. cuidados terciários, LDL-colesterol do caso índice e história familiar de níveis elevados de LDL-colesterol foram preditores independentes associados a um maior número de familiares inscritos. Conclusões: Programas de rastreamento genético em cascata da hipercolesterolemia familiar podem prever o recrutamento da família com base nas características do caso índice. Esta informação pode ser útil para criar abordagens de rastreamento melhores e mais eficazes para indivíduos em risco.
Abstract Background: Genetic cascade screening is the most cost-effective method for the identification of individuals with familial hypercholesterolemia (FH), but the best strategies for the enrollment of at-risk individuals in a FH screening program are not fully known. Objective: The aim of this study is to identify the best predictors of familial enrollment into genetic screening, using features derived from tested probands. Methods: One hundred and eighty-three index-cases (ICs) with a positive genetic result that had relatives screened from 01/2011 to 07/2015 were included. The response variable was the number of relatives for each enrolled IC. All variables in the study were based on ICs’ derived clinical and socioeconomical features. The effect size of predictor variables were obtained through a general linear model using a negative binomial regression link function. Significance was considered with a p < 0.05. Results: Mean IC age when enrolling into the program was 50 years old; 78.1% of individuals reported knowledge of relatives with dyslipidemia. Mean baseline LDL-cholesterol level was 316 ± 90 mg/dL. Referral origin through the cascade program website vs. tertiary care, IC LDL-cholesterol and familial history of high LDL-cholesterol levels were independent predictors associated with a higher number of enrolled relatives. Conclusions: Our data suggest that FH cascade screening programs can predict family enrollment based on IC features. This information may be useful for devising better and more effective screening approaches for at-risk individuals.

Resumo O objetivo deste estudo foi avaliar a dureza Knoop de diferentes cores de um cimento resinoso fotoativado diretamente ou através da interposição de um disco de cerâmica, medindo 15 min ou 24 h após exposição à luz, em diferentes profundidades. Amostras do cimento resinoso (Variolink Veneer) em sete cores foram fabricados num molde de elastômero, coberto com tira de poliéster, seguido de um disco cerâmico (IPS e.max Press) com 0.7 mm de espessura e fotoativado por 20 s com o aparelho LED (IPS e.max Press). O cimento resinoso fotoativado foi transversalmente desgastado na porção média e os valores de microdureza Knoop foram obtidos após 15 min após exposição à luz e após armazenagem em água deionizada à 37 °C por 24 h. Cinco penetrações foram feitas na secção transversal à 100 e 700 μm da superfície de topo. Dez amostras foram confeccionadas para cada condição de teste. Os dados foram submetidos à Análise de Variância em esquema de parcelas subdivididas (cor, tempo pós-ativação, modo de ativação e profundidade), seguido pelo teste de Tukey post hoc (α=0,05). Diferença significante para a cor (p<0,0001), modo de ativação (p<0,001), tempo pós-ativação (p<0,0001) e profundidade (p<0,0001) foi detectada. Nenhuma interação significante foi encontrada (p>0,05), exceto para a interação cor x tempo pós-ativação (p<0,0045) e modo de ativação x tempo pós-ativação (p<0,0003). A cor do cimento resinoso teve significante efeito na dureza Knoop. A ativação indireta através do material cerâmico reduziu significativamente a dureza Knoop. A dureza Knoop aumentou significativamente após 24 h em todas as cores do cimento comparados aos valores obtidos após 15 min. A profundidade do cimento resinoso reduziu significativamente os valores de dureza Knoop.
Abstract The aim of this study was to evaluate Knoop hardness of different shades of a resin cement light-cured directly or through ceramic discs, measured 15 min or 24 h after light exposure, and at different depths. Specimens of a commercial resin cement (Variolink Veneer) in seven shades, were fabricated in an elastomeric mold, covered with a mylar strip, a 0.7 mm thick ceramic disc (IPS e.max Press) was placed and the cement was light-activated for 20 s using a blue LED (Radii-Cal). The cured resin cement specimens were transversely wet-flattened to their middle portion and microhardness (Knoop) values were recorded at 15 min after light exposure and after deionized water storage at 37 ºC for 24 h. Five indentations were made in the cross-sectional area at 100 and 700 μm depths from the top surface. Ten specimens were made for each test conditions. Data were submitted to ANOVA split-plot design (shade, post-cure time, mode of activation and depth), followed by Tukey post hoc test (α=0.05). Significant differences for shade (p<0.0001), mode of activation (p<0.001), post-cure time (p<0.0001) and depth (p<0.0001) were detected. No significant interactions (p>0.05) were found, except for shade x post-cure time (p<0.0045) and mode of activation x post-cure time (p<0.0003). Resin cement shade has a significant effect on Knoop hardness. Indirect activation through a ceramic material reduced significantly Knoop hardness. Hardness Knoop significantly increased after 24 h in all cements shades compared to values obtained after 15 min. Resin cement depth significantly reduced Knoop hardness.

ABSTRACT This experiment was conducted to evaluate growth performance and carcass characteristics of barrows from 25 to 100 kg fed diets with different dietary net energy (NE) levels. Seventy-two barrows with initial body weight (BW) of 25.19±2.13 kg were allotted using a completely randomized block design to one of six dietary NE treatments (2300, 2380, 2460, 2540, 2620, and 2700 kcal kg−1), which had two pigs per replicate and six replicates per treatment. Diets were formulated to be fed in three phases (25 to 60, 60 to 70, and 70 to 100 kg BW). The six different dietary NE densities were met by adding soybean oil in place of the inert ingredient (kaolin) to a corn-soybean meal-based diet. Increasing dietary NE decreased average daily feed intake and average daily standardized ileal digestible (SID) lysine intake in all of the three phases evaluated and improved the feed:gain ratio and SID lysine:gain ratio in the first and third phases. In the first and second phases, average daily NE intake and NE:gain ratio were similar among treatments, but NE increased and NE:gain worsened during the last phase as dietary NE increased. Average daily gain was not affected by dietary NE in the first and second phases; however, it improved in the last phase. Backfat was thicker, and lean percentage was reduced by increasing the dietary NE in all three phases of this study. Thus, barrows consume less feed, but carcass fat increases if dietary NE is increased from 2300 to 2700 kcal kg−1.

ABSTRACT: Improved spray deposition can be attained by electrostatically charging spray droplets, which increases the attraction of droplets to plants and decreases operator exposure to pesticide and losses to the environment. However, this technique alone is not sufficient to achieve desirable penetration of the spray solution into the crop canopy; thus, air assistance can be added to the electrostatic spraying to further improve spray deposition. This study was conducted to compare different spraying technologies on spray deposition and two-spotted spider mite control in cut chrysanthemum. Treatments included in the study were: conventional TJ 8003 double flat fan nozzles, conventional TXVK-3 hollow cone nozzles, semi-stationary motorized jet launched spray with electrostatic spray system (ESS) and air assistance (AA), and semi-stationary motorized jet launched spray with AA only (no ESS). To evaluate the effect of these spraying technologies on the control of two-spotted spider mite, a control treatment was included that did not receive an acaricide application. The AA spraying technology, with or without ESS, optimized spray deposition and provided satisfactory two-spotted spider mite control up to 4 days after application.

ABSTRACT This study was carried out to evaluate the levels of digestible phosphorus in diets for barrows with a high potential for lean meat deposition from 50 to 80 kg. Eighty barrows, with an initial weight of 47.93±3.43 kg, were distributed in completely randomized blocks, with each group given five levels of digestible phosphorus (1.86, 2.23, 2.61, 2.99, and 3.36 g kg−1). There were eight replicates, and two animals per experimental unit. Phosphorus levels did not significantly influence feed intake, weight gain, or feed conversion ratio. Daily digestible phosphorus intake increased linearly as levels of phosphorus in the diet were increased. Phosphorus levels did not significantly influence muscle depth, loin eye area, backfat thickness, or the percentage and quantity of lean meat in the carcass. A linear increase was observed for feeding cost as the levels of digestible phosphorus in the diet were increased, and the level of 1.86 g kg−1 cost 29.4% less when compared with the level of 2.61 g kg−1. The dry matter, natural matter, the coefficient of the residue, and volatile solids of the waste were not significantly influenced by phosphorus levels. Conversely, it was possible to observe an increasing linear effect for total solids, total phosphorus, and total nitrogen in the waste of animals receiving diets with increased levels of digestible phosphorus. The level of 1.86 g kg−1, which corresponded to a daily intake of 4.77 g−1 of digestible phosphorus, meets the requirements of barrows weighing 50 to 80 kg.

RESUMO: Objetivo: Avaliar o consumo habitual de antioxidantes (vitaminas A, E e C, selênio e zinco) e identificar fatores associados ao baixo consumo em adultos. Métodos: Estudo transversal com 14.660 participantes (35 a 74 anos) da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). O consumo de antioxidantes e energia total foi determinado por Questionário de Frequência Alimentar e analisado com auxílio do software NDSR. O consumo dos antioxidantes foi ajustado pela energia total e dividido em quintis. Variáveis socioeconômicas foram analisadas e incluídas no modelo de regressão logística para identificar fatores associados ao baixo consumo. Resultados: O consumo energético (kcal/dia) foi maior em homens (3.152 ± 1.026 versus 2.613 ± 905; p < 0,001) enquanto que o consumo de todos os antioxidantes (principalmente as vitaminas A e C e o selênio) foi maior em mulheres. O baixo consumo de antioxidantes se associou significativamente ao sexo masculino (OR = 3,5; IC95% 3,11 - 4,0), à menor escolaridade (OR = 3,1; IC95% 2,42 - 3,87), à menor renda (OR = 4,4; IC95% 3,67 - 5,36), à menor faixa etária (OR = 5,5; IC95% 4,27 - 7,16), ao estado de magreza (OR = 2,7; IC95% 1,36 - 5,18), ao relato do não uso de suplemento (OR = 1,95; IC95% 1,6 - 2,38) como polivitamínicos e minerais e a não alteração de hábitos alimentares nos últimos seis meses (OR = 2,0; IC95% 1,75 - 2,29). Conclusão: O maior consumo de frutas e legumes está envolvido no maior consumo de antioxidantes em mulheres. As políticas para aumento do consumo desses nutrientes precisam ser dirigidas para os segmentos de menores renda, escolaridade e faixa etária.
ABSTRACT: Objective: To quantify the antioxidant consumption (vitamins A, C and E and minerals selenium and zinc) and to identify factors associated to low consumption of these nutrients. Methods: Cross-sectional study with 14,660 participants (35 to 74 years-old) investigated in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline. Consumption of antioxidants and energy was determined by a Food Frequency Questionnaire and analyzed using the NDSR software. Antioxidant consumption was adjusted to total energy and divided in quintiles. A logistic regression analysis was used to identify socioeconomic factors associated with low intake of these nutrients. Results: Consumption of energy (kcal/day) was higher in men (3,152 ± 1,026 versus 2,613 ± 905; p < 0.001) whereas the consumption of all antioxidants (mainly vitamins A and E and selenium) was higher in females. Low antioxidant consumption was associated to male sex (OR = 3.5; 95%CI 3.11 - 4.0) and to lower education (OR = 3.1; 95%CI 2.42 - 3.87), income (OR = 4.4; 95%CI 3.67 - 5.36) and age (OR = 5.5; 95%CI 4.27 - 7.16), as well as to thinness (OR = 2.7; 95%CI 1.36 - 5.18) and when participants did not reported the use of supplements (OR = 1.95; 95%CI 1.6 - 2.38) or change of eating habits in the last six months (OR = 2.0; 95%CI 1.75 - 2.29). Conclusion: The greater intake of fruits and vegetables is likely to be involved in the higher consumption of antioxidants in females. General policies to increase the consumption of such nutrients should be directed to groups of lower income, education and age.

INTRODUCTION: Dengue is the most prevalent arboviral disease in tropical areas. In Mato Grosso, outbreaks are reported every year, but studies on dengue in this state are scarce. METHODS: Natural transovarial infection of Aedes aegypti by a flavivirus was investigated in the Jardim Industriário neighborhood of Cuiabá, Mato Grosso. Eggs were collected with ovitraps during the dry, intermediate, and rainy seasons of 2012. After the eggs hatched and the larvae developed to adulthood, mosquitoes (n = 758) were identified and allocated to pools of 1-10 specimens according to the collection location, sex, and climatic period. After RNA extraction, multiplex semi-nested RT-PCR was performed to detect the four dengue virus (DENV) serotypes, yellow fever virus, West Nile virus and Saint Louis encephalitis virus. RESULTS: DENV-4 was the only flavivirus detected, and it was found in 8/50 pools (16.0%). Three of the positive pools contained females, and five contained males. Their nucleotide sequences presented 96-100% similarity with DENV-4 genotype II strains from Manaus, Amazonas. The minimum infection rate was 10.5 per 1000 specimens, and the maximum likelihood estimator of the infection rate was 11.6 (95% confidence interval: 4.8; 23.3). CONCLUSIONS: This study provides the first evidence of natural transovarial infection by DENV-4 in Ae. Aegypti in Mato Grosso, suggesting that this type of infection might serve as a mechanism of virus maintenance during interepidemic periods in Cuiabá, a city where dengue epidemics are reported every year. These results emphasize the need for efficient vector population control measures to prevent arbovirus outbreaks in the state.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

The objective of this study was to evaluate the performance, the carcass and meat characteristics of ewes supplemented with magnesium oxide. Eighteen 6-year-old Santa Ines ewes were used in a completely randomized experimental design, where three levels of supplementation (0.0, 0.1 and 0.2% magnesium oxide in the concentrate) were tested, with six replicates. Final weight, weight gain, feed intake and feed conversion were not affected by levels of magnesium supplementation. Hot and cold carcass weights showed linear increasing and quadratic responses, respectively, according to supplementation with magnesium. Carcass measurements such as length, depth, and measures of arm and leg were not affected by supplementation. Depth and width of the longissimus muscle and rib-eye area were not affected; however, marbling and ether extract increased linearly with supplementation. Water loss and color were not affected. Lipid oxidation and shear force were not affected by supplementation, while the myofibrillar fragmentation index showed a quadratic regression. There was a linear decrease in pH with magnesium supplementation. Supplementation with magnesium can improve carcass and meat pH, but can act negatively by increasing the amount of marbling and ether extract of meat.
