Abstract Objective To evaluate the iodine sufficiency of pregnant women assisted in a University Hospital of Minas Gerais, and to correlate the urinary concentrations of maternal iodine with the fetal thyroid hormone levels at birth. Methods Urinary iodine concentrations from 30 pregnant women with a singleton pregnancy and gestational age lower than 20 weeks were analyzed. Occasional samples of the mothers' urine were collected for the urinary iodine concentration dosage, and these were correlated with the newborns' thyroid-stimulating hormone (TSH) levels. Results The median iodine urinary concentration of this study's pregnant women population was 216.73 mcg/l, which is proper for the group, following the World Health Organization (WHO). No cases of neonatal hypothyroidism were reported in the study, which corroborates the iodine sufficiency in this population sample. Conclusion This study shows that despite the increased demand for iodine from pregnant women and the Brazilian Health Regulatory Agency (ANVISA) recommendation of 2013 for reduction of salt iodization levels, the population of pregnant women attended in the prenatal ambulatory of normal risk from the Federal University of Minas Gerais is considered sufficient in iodine. As a higher sample is necessary for the confirmation of these findings, it is too early to recommend the universal supplementation of iodine for Brazilian pregnant women, and more studies must be carried out, considering that iodine supplementation for pregnant women in an area of iodine sufficiency is associated to the risks of the fetus's excessive exposure to iodine.

Resumo Objetivo Avaliar a suficiência iódica de gestantes atendidas em um Hospital Universitário de Minas Gerais e correlacionar as concentrações urinárias de iodo materno com os níveis de hormônios tireoidianos fetais ao nascimento. Métodos Foi analisada a concentração urinária de iodo de 30 gestantes com gestação única e idade gestacional menor que 20 semanas. Foram coletadas amostras ocasionais de urina materna para dosagem da concentração urinária de iodo, e estas foram correlacionadas com os níveis de hormônio estimulante da tiroide (TSH) dos recémnascidos. Resultados A mediana da concentração urinária de iodo das gestantes estudadas foi de 216,73 mcg/L, sendo adequada para o grupo segundo a Organização Mundial de Saúde (OMS). Não houve nenhum caso de hipotireoidismo neonatal no estudo, o que corrobora a suficiência de iodo nesta amostra populacional. Conclusão Esse estudo demonstra que apesar do aumento da demanda de iodo pelas gestantes e da recomendação da Agência Nacional de Vigilância Sanitária (ANVISA) de 2013 da redução dos níveis de iodação do sal, a população de gestantes atendidas no ambulatório de pré-natal de risco habitual da Universidade Federal de Minas Gerais é considerada suficiente em iodo. Apesar de uma maior amostragem ser necessária para a confirmação destes achados, é cedo para recomendar a suplementação universal de iodo para as gestantes brasileiras e mais estudos precisam ser realizados, levando-se em conta que a suplementação de iodo para gestantes em áreas suficientes em iodo está associada aos riscos da exposição excessiva de iodo ao feto.

ABSTRACT. The aim of this study was to characterize four corn and sorghum co-products (DDG) in terms of their protein and carbohydrate fractions; we also evaluated the effects of substituting the protein source of the conventional supplement by DDG on consumption and nutrient digestibility in confined finishing cattle. Thirty-six male Nellore cattle with a mean age of 24 months were used. The treatments were: FA: concentrate with corn as an energy source and cottonseed meal as a protein source; DDG50: concentrate with a 50% substitution of the FA protein source by DDG; DDG100: concentrate with 100% substitution of the FA protein source by DDG. The experimental design was completely randomized with three treatments and three replicates (pens) containing four animals per pen. We found that the use of DDG in the finishing phase did not interfere with the animals’ food intake or the digestibility of the nutrients (p > 0.05). Nutrients were used by the animals; therefore, DDGs may be viable substitutes of cottonseed meal. We conclude that the bromatological composition of this co-product is influenced a lot during processing; therefore, the nutritional values of this co-product present in the composition tables may not be true.

Resumo Os principais sinais e sintomas da insuficiência venosa crônica são dor, edema, varizes e alterações teciduais, condições que comprometem a funcionalidade e qualidade de vida. Visando amenizar esses prejuízos, o manejo da doença envolve uma ampla modalidade de intervenções; entre elas, o exercício terapêutico. Esta pesquisa apresenta as evidências existentes sobre a efetividade dos exercícios terapêuticos na qualidade de vida, dor e funcionalidade da insuficiência venosa crônica. Efetuou-se uma busca nas bases de dados CENTRAL, CINAHL, LILACS, MEDLINE, PEDro, SciELO, Science Direct, Scopus e Web of Science. Dos 2.961 resultados, quatro atenderam aos critérios de elegibilidade. Desses, apenas um estudo mostrou benefícios dos exercícios para melhora da qualidade de vida e redução da dor. Os demais apresentaram baixa qualidade metodológica. Portanto, as evidências existentes são insuficientes para indicar ou contraindicar os exercícios terapêuticos para melhoria da qualidade de vida, dor e funcionalidade em pacientes com insuficiência venosa crônica.

Abstract The main signs and symptoms of chronic venous insufficiency are pain, edema, varicose veins, and tissue changes; conditions that compromise functionality and quality of life. Management of the disease aims to mitigate these losses and involves a wide range of interventions, one of which is therapeutic exercise. This article presents the existing evidence on the effectiveness of therapeutic exercises for quality of life, pain, and functionality in chronic venous insufficiency. Searches were run on the databases CENTRAL, CINAHL, LILACS, MEDLINE, PEDro, SciELO, Science Direct, Scopus, and Web of Science. Four of the 2,961 results met the eligibility criteria. Only one of these studies showed benefits of exercise for improving quality of life and reducing pain. The others had low methodological quality. The existing evidence is therefore insufficient to indicate or contraindicate therapeutic exercises for improvement of quality of life, pain, and functionality in patients with chronic venous insufficiency.

RESUMO O gênero Brycon compreende um grupo de espécies de peixes de grande importância socioeconômica e biológica no Brasil. Entretanto, o conhecimento genético dessas espécies é escasso, principalmente no caso do Brycon falcatus. Diante disso, objetivou-se verificar a transferibilidade de primers heterólogos em B. falcatus. Foram avaliados primers heterólogos provenientes das espécies B. opalinus, B. hilarii, B. insignis, B. orbignyanus, B. amazonicus, Prochilodus argenteus, Prochilodus lineatus, Piaractus mesopotamicus e Colossoma macropomum. Os primers que demonstraram melhores padrões de amplificação foram aplicados a uma amostra de 22 indivíduos e os parâmetros genéticos foram calculados. Nove primers apresentaram resultados satisfatórios de amplificação cruzada com B. falcatus: BoM5 (Brycon opalinus), Bh8, Bh13 e Bh16 (B. hilarii); Borg59 (Brycon orbignyanus); Bag22 (B. amazonicus); Par12 and Par80 (Prochilodus argenteus) e Cm1A8 (Colossoma macropomum). Os parâmetros genéticos (número de alelos, alelos efetivos, riqueza de alelos e heterozigosidade esperada e observada) e o conteúdo de informação polimórfica (PIC) demonstraram a viabilidade da utilização dos primers para análises genéticas populacionais. Nosso estudo demonstra o potencial de transferibilidade de marcadores microssatélites de espécies relacionadas e até de gêneros diferentes para B. falcatus, fornecendo ferramentas úteis para futuros estudos genéticos populacionais nessa espécie.

ABSTRACT The genusBryconcomprises fish species of significant socioeconomic and biological importance in Brazil. Despite that, the genetic knowledge about these species is scarce, especially regardingBrycon falcatus. Thus, the objective of this study was to evaluate the transferability of heterologous microsatellite primers inB. falcatus for the first time. Heterologous primers obtained from B. opalinus, B. hilarii, B. insignis, B. orbignyanus, B. amazonicus, Prochilodus argenteus, Prochilodus lineatus, Piaractus mesopotamicus, and Colossoma macropomum were evaluated. The primers that showed the best amplification patterns were applied to a sample of 22 individuals and the genetic parameters were calculated. Nine primers displayed satisfactory cross-amplification withB. falcatus: BoM5 (Brycon opalinus); Bh8, Bh13 and Bh16 (B. hilarii); Borg59 (B. orbignyanus); Bag22 (B. amazonicus); Par12 and Par80 (P. argenteus), and Cm1A8 (C. macropomum). The genetic parameters (number of alleles, effective alleles, allele richness, and expected and observed heterozygosity) and the polymorphic information content (PIC) confirmed the viability of these primers for population genetics analyses. Our study demonstrates the potential of transferability of microsatellite markers from related species and even different genera to B. falcatus, providing usefull tools for future population genetic studies in this species.

RESUMO: Brycon gouldingi é uma espécie de peixe neotropical com importância socioeconômica e ambiental na Bacia do Tocantins-Araguaia. Estudos genéticos nessa espécie ainda são escassos, dificultando o conhecimento sobre a estrutura populacional e a diversidade genética nos estoques naturais e em cativeiro. O objetivo do presente estudo foi avaliar a transferibilidade de primers microssatélites heterólogos em B. gouldingi. Foram avaliados um total de 30 primers de oito espécies: Brycon hilarii, Brycon opalinus, Brycon cephalus, Brycon orbignyanus, Prochilodus lineatus, Prochilodus argenteus, Piaractus mesopotamicus e Colossoma macropomum. Os primers que demonstraram melhores padrões de amplificação foram aplicados em 20 espécimes de B. gouldingi para os cálculos dos parâmetros genéticos. Sete dos 30 primers apresentaram resultados satisfatórios de transferibilidade, sendo seis oriundos do gênero Brycon: Bh13 (B. hilarii), BoM5, BoM13 (B. opalinus), Borg9, Borg13 e Borg59 (B. orbignyanus), e um oriundo de P. argenteus (Par80). Os primer das outras espécies testados mostraram inespecificidade ou monomorfismo, sendo excluídos das análises. O número de alelos variou de dois (Borg13 e Borg59) a três (Bh13, BoM5, BoM13, Borg9 e Par80), com tamanhos entre 103 pb (BoM5) e 430 pb (Borg9). Quatro primers apresentaram evidências de alelos nulos (BoM13, Borg9, Borg13 e Par80), o que provavelmente inferiu sobre o desvio de Hardy-Weinberg nos mesmos. Concluindo, sete primers foram validados para a amplificação cruzada em B. gouldingi e poderão ser utilizados em futuros estudos com essa espécie.

ABSTRACT: Brycon gouldingi is a species of neotropical fish of socioeconomic and environmental importance in the Tocantins-Araguaia Basin. Genetic studies on this species are still limited, making it difficult to evaluate the population structure and genetic diversity in natural and captive stocks. Here, we aimed to evaluate the transferability of heterologous microsatellite primers in B. gouldingi. A total of 30 primers for eight species were evaluated: Brycon hilarii, Brycon opalinus, Brycon cephalus, Brycon orbignyanus, Prochilodus lineatus, Prochilodus argenteus, Piaractus mesopotamicus, and Colossoma macropomum. The primers that showed the best amplification patterns were applied to 20 specimens of B. gouldingi, and their genetic parameters were assessed. Among the 30 primers, seven showed satisfactory transferability, six of which belonged to the genus Brycon: Bh13 (B. hilarii), BoM5, BoM13 (B. opalinus), Borg9, Borg13, and Borg59 (B. orbignyanus), and one belonged to P. argenteus (Par80). The primers for the other species tested showed non-specificity or monomorphism; and were therefore, excluded from the analyses. The number of alleles ranged between two (Borg13 and Borg59) and three (Bh13, BoM5, BoM13, Borg9 and Par80), with sizes varying between 103 bp (BoM5) and 430 bp (Borg9). Four primers showed evidence of null alleles (BoM13, Borg9, Borg13, and Par80), which could probably be attributed to the respective Hardy-Weinberg deviation. Thus, seven primers were validated for cross-amplification in B. gouldingi, which may be used in future studies involving this species.

OBJECTIVES Show that hidden endemic leprosy exists in a municipality of inner São Paulo state (Brazil) with active surveillance actions based on clinical and immunological evaluations. METHODS The study sample was composed by people randomly selected by a dermatologist during medical care in the public emergency department and by active surveillance carried out during two days at a mobile clinic. All subjects received a dermato-neurological examination and blood sampling to determine anti-PGL-I antibody titers by enzyme-linked immunosorbent assay (ELISA). RESULTS From July to December 2015, 24 new cases of leprosy were diagnosed; all were classified as multibacillary (MB) leprosy, one with severe Lucio's phenomenon. Seventeen (75%) were found with grade-1 or 2 disability at the moment of diagnosis. Anti-PGL-I titer was positive in 31/133 (23.3%) individuals, only 6/24 (25%) were positive in newly diagnosed leprosy cases. CONCLUSIONS During the last ten years before this study, the average new case detection rate (NCDR) in this town was 2.62/100,000 population. After our work, the NCDR was raised to 42.8/100,000. These results indicate a very high number of hidden leprosy cases in this supposedly low endemic area of Brazil.

We describe the case of a 32-year-old male patient that sought medical treatment complaining of severe pain in his second and third right-hand fingers. The symptoms had started two hours before. The hypotheses of spider bite, scorpion or insect sting and injury caused by a foreign body were considered in the differential diagnoses. On dermoscopy, two foreign bodies were identified on his skin. After extraction, we concluded that they were wasp stingers.
