ABSTRACT BACKGROUND: Current research supports the fact that prophylactic ankle taping (AT) is effective in preventing ankle injuries in amateur and elite sports athletes. OBJECTIVE: This study aimed to investigate the effect of AT on balance, knee valgus during drop jump and single-leg countermovement jump (SL-CMJ) landings, and ankle range of motion (ROM) restriction in healthy participants. DESIGN AND SETTING: A cross-sectional observational study was conducted at the Universidad Europea de Madrid, Madrid, Spain. METHODS: Participants: Thirty-nine healthy individuals participated in this study and performed the movements under two conditions (with and without tape). Outcome measurements: ankle ROM, balance, SL-CMJ height, flight time, ground time, and knee valgus. Before any intervention, a random process was developed with a 1:1 allocation ratio, and the participants were assigned to groups A (tape-no tape) and B (no tape-tape). RESULTS: Significant differences between tape and no-tape moments were observed for drop jump knee valgus flexion (P = 0.007), with an increase in knee valgus in participants with ankle taping. Similarly, the Y-balance testshowed a significant decrease in all variables (P = 0.001 and), ankle dorsiflexion (P = 0.001) in participants with ankle taping. CONCLUSIONS: AT is effective for immediate ankle ROM restriction. However, an increase in knee valgus during drop jump task and a decrease in lower limb balance were observed during drop jump task. Based on these results, it can be concluded that AT application in healthy individuals should not be recommended as it results in increase in injury risk factors.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract Stromatolites are laminated biosedimentary structures of great importance for paleobiological, paleoecological, and paleoenvironmental analyses, mainly in Precambrian rocks. Their value is related to the glimpse of past life recorded in their lamination, fabric, and, eventually, due to the preservation of organic matter, including microfossils, and because their deposition is directly influenced by environmental conditions. Although stromatolites are widely described in microscopic scale, there is a lack of standardization of their nomenclature, precluding better paleoenvironmental and paleobiological interpretations. In this study, we propose a guide for the microscopic analysis of fossil stromatolites and, possibly, thrombolites, and provide a review of specialized literature and the bibliometric context of main terms. The goal is to contribute to the improvement of their application through systematization of microscopic data, in the face of novel paleoecological and paleobiological approaches and for astrobiological prospection for microbialites in therock record of Mars. analyses rocks lamination fabric eventually matter microfossils conditions scale nomenclature interpretations study possibly thrombolites terms data Mars

Abstract Background: Maternal mortality rates in Brazil remain above the goals established by the United Nations Sustainable Development Goals. Heart disease is estimated to affect 4% of all pregnancies and remains by itself the main indirect obstetric cause of maternal death. In the last decades, a significant improvement in the prognosis of heart diseases has made pregnancy possible in women with heart disease and provided better maternal and fetal outcomes. Objective: To establish a multicenter Brazilian Registry of pregnant women with heart disease; to study the causes of immediate and late maternal mortality; and to assess the prevalence of heart disease in the country’s macro-regions. Method: This is an observational study, with retrospective and prospective stages, of the clinical and obstetric progression of pregnant women with heart disease. These women consecutively received care during pregnancy and will be followed up for up to a year after delivery at public and private hospitals with infrastructure for the execution of this project, a principal investigator, and approval by Ethics and Research Committees. Results: Our results will be presented after data collection and statistical analysis, aiming to demonstrate immediate and late maternal mortality rates, as well as the prevalence of heart disease in the country and its cardiovascular and obstetric complications during pregnancy. Conclusion: REBECGA will be the Brazilian Registry of heart disease and pregnancy and it will contribute to planning preventive measures, raising financial resources for the improvement of high-risk prenatal care, and reducing immediate and late maternal mortality due to heart disease.

RESUMO: Este artigo visa a contribuir para o estudo sobre a reação do mercado acionário a ponto de gerar retornos anormais ou retornos anormais acumulados significativos no período do impeachment brasileiro. Por meio da hipótese do mercado eficiente (HME), em sua forma semiforte, objetivou-se verificar se o impeachment presidencial ocorrido no Brasil em 2016, em 3 datas distintas, proveu a reação esperada do mercado acionário na Bolsa de Valores, Mercadorias e Futuros (BM&FBOVESPA). O tema é relevante, pois aborda aspectos políticos e de teoria econômica e suas interações nos mercados acionários. Impacta na área de mercados de capitais, porque sugere que agentes econômicos podem, por meio de suas expectativas e informações, verificar reações adversas no mercado. A metodologia empregada analiticamente incorpora breve revisão de literatura como base teórica acerca de instituições envolvidas e referencia historicamente eventos do impeachment. Quantitativamente, a metodologia consiste no estudo de eventos, de maneira que as expectativas são observadas por meio de modelos de regressão de séries temporais baseados nos modelos autorregressivos de médias móveis (autoregressive-moving-average- ARMA). O resultado encontrado, sob 3 importantes eventos que culminaram no impeachment presidencial brasileiro de 2016, foi que não se determinou nenhuma estatística significativa, em nível de 5%, em todas as janelas estimadas e em todos os eventos. Estatisticamente, não se pôde rejeitar a hipótese de que os retornos anormais e os retornos anormais acumulados fossem iguais a 0. Então, considerou-se que os mercados estavam bem informados em relação aos eventos, nessa situação específica, ou seja, segundo a HME, em sua forma semiforte, os mercados reagiram conforme o esperado.

ABSTRACT This article aims at contributing to study the stock market’s reaction up to the point of generating significant abnormal returns or cumulative abnormal returns within the Brazilian impeachment period. By means of the efficient market hypothesis (EMH), in its semi-strong form, the purpose was verifying whether the presidential impeachment that took place in Brazil in 2016, in 3 different dates, brought the expected reaction from the stock market on the Brazilian Stocks, Commodities and Futures Exchange (BM&FBOVESPA). The theme is relevant, as it addresses aspects of politics and economic theory and their interactions in stock markets. It impacts in the area of capital markets, because this suggests that economic players can, through their expectations and information, see adverse reactions in the market. The methodology analytically employed encompasses a brief literature review as a theoretical basis about the institutions involved and it refers historically to impeachment events. Quantitatively, the methodology consists in the study of events, so that the expectations are observed by means of time-series regression models based on the autoregressive-moving-average (ARMA) models. The result found, under three major events that culminated in the 2016 Brazilian presidential impeachment, was that no significant statistics has been determined, at a 5% level, in all estimated windows and in all events. Statistically, it was not possible to reject the hypothesis that the abnormal returns and the cumulative abnormal returns equal zero. So, the markets have been considered to be well-informed regarding the events, in this specific situation, i.e. according to the EMH, in its semi-strong form, the markets have reacted as expected.

ABSTRACT: Traditional method of soil survey is expensive, slow, and must be carried out by experienced researchers. Thus, advances in soil observation technologies and the need to obtain information quickly by modern techniques have intensified the use of proximal sensing. This study characterized surface reflectance spectra (A horizon) and related them to traditional soil classification, based on morphological, physical, and chemical properties of representative pedogenetic profiles, developed in two toposequences of the Distrito Federal, Brazil. In the toposequences, 15 soil profiles were selected for a complete morphological description and sampling for laboratory analyses. Soil-landscape relationships were established, and profiles were classified to the fourth level of the Brazilian Soil Classification System (SiBCS). Classes of similar soils were grouped based on their surface spectra, resulting in spectral curves of 10 representative soils in the studied area. The Morphological Interpretation of Reflectance Spectrum (MIRS) and second derivative of the Kubelka-Munk (KM) function were applied to the soil spectra. The clustered soils were similar, mainly in terms of color, textural class, and organic matter content. Groups based on soil physical and chemical properties and on surface and subsurface colors were similar to those determined by surface reflectance. The identification of soil-landscape relationships was fundamental to understand the genesis and distribution of the soils, which had similar chemical and physical properties to their parent materials. The analysis of clusters based on soil surface reflectance proved efficient in determining groups of soil classes with similar properties. Surface reflectance data were related to the soil surface and subsurface properties determined by traditional soil sample analyses, since the two approaches formed similar groups. The simultaneous interaction of soil properties was assessed by MIRS analysis, while the second derivative of the KM function adequately quantified the mineralogy of the spectra.

Resumo Introdução: Um adequado estado de hidratação durante a atividade esportiva é essencial para a manutenção da boa saúde, porém a relação entre hidratação, proteinúria e esportes é pouco estudada. Objetivo: analisar a influência de suplemento hidroeletrolítico (bebida esportiva isotônica) como estratégia de reidratação sobre o estado de hidratação e proteinúria após treino de Karate. Métodos: Dez atletas participaram deste estudo. Na primeira sessão de treino padronizado, denominada sessão de treino de observação (STO), os atletas se reidrataram segundo seus hábitos; na segunda sessão de treino padronizado, denominada sessão de treino de intervenção nutricional (STIN), foi seguido um protocolo ideal de prática de hidratação, utilizando-se de suplemento hidroeletrolítico como líquido reidratante durante o treino. O estado de hidratação foi verificado pelo monitoramento do peso corporal antes e após o treino, pela gravidade específica da urina pré e pós-treino e pelo volume urinário pós-treino. De forma a observar a influência da prática de hidratação sobre a função renal, a proteinúria pós-exercício foi medida. Resultados: Observou-se uma diferença estatisticamente significativa na densidade urinária entre as amostras coletadas pré e pós-exercício apenas na STIN (p = 0,047). Quando comparados entre sessões, houve menor variação ponderal (p = 0,011) e maior volume urinário (p < 0,001) no treino com intervenção nutricional. Na STO, houve um percentual mais elevado de atletas que apresentaram proteinúria (70%) em comparação a STIN (50%) na amostra de urina coletada após o treino. Conclusão: O uso de suplemento hidroeletrolitico como prática de hidratação por atletas de karate favoreceu a reidratação durante uma sessão de treino e reduziu a proteinúria pós-treino.

Abstract Introduction: Adequate hydration status in the sport is essential for good health, yet the relationship between hydration, proteinuria and sports is little studied. Objective: To analyze the influence of an isotonic sports drink as rehydration strategy on the hydration status and proteinuria after karate training. Methods: Ten athletes participated in this study. In the first session of standard training, called observation training session (STO), the athletes hydrated themselves according to their habits, and in the second session of standard training, called nutritional intervention training session (STIN), an ideal practice of hydration protocol was followed, using an isotonic sports drink as a rehydration liquid during the training. The hydration status was verified by monitoring the body weight before and after training, the urine specific gravity pre-and post-training and the urine volume post-training. To observe the influence of practice of hydration on the renal function post exercise proteinuria was measured. Results: We observed a statistically significant difference in urine density between the samples pre- and post-exercise only on STIN (p = 0.047). When we compare the sessions, there was a lower variation in body weight (p = 0.011) and higher urinary volume (p < 0.001), on nutritional intervention training. In STO, there was a higher percentage of athletes who showed proteinuria (70%) compared to the STIN (50%) in the urine sample after training. Conclusion: The use of isotonic sports drink as practice of hydration by karate athletes promoted rehydration during one session of training and reduce post-training proteinuria.

RESUMO Este trabalho foi desenvolvido com objetivo de avaliar o desempenho dos índices de Nesterov e Fórmula de Monte Alegre (FMA) no ambiente Lichinga (norte de Moçambique), de modo a sugerir o melhor índice a ser usado nesta região. Para a materialização desta pesquisa, foram usados dados meteorológicos diários (temperatura, precipitação e umidade relativa) e dados de registro de ocorrências dos incêndios florestais de um período de três anos (2010 a 2012). Os dados meteorológicos foram fornecidos pelo Instituto de Investigação Agronômica de Moçambique em Lichinga (IIAM-Lichinga) e o banco de dados de registro de ocorrências de incêndios foi providenciado pelo Centro de Controle e Monitoramento de Incêndios Florestais (CCMIF), da empresa Chikweti Forest of Niassa. Na sequência, foram calculados os índices de perigo de incêndios e o grau de perigo diário para os dois índices, tendo-se observado a predominância do grau de perigo muito alto em quase todos os anos, com um porcentual de 52,65% para o FMA e 37,96% para o índice Nesterov. Com valores de Skill Score (SS) de 0,11 e Porcentagem de Sucesso (PS) de 44,82%, o índice Nesterov mostrou melhor desempenho para o ambiente de Lichinga, ao contrário do FMA que apresentou um fraco desempenho com os valores de 0,07 de SS e 35,62% de PS.

ABSTRACT This study was conducted in order to evaluate the performance of Nesterov indexes and of Monte Alegre formula (FMA) in Lichinga environment (northern Mozambique) in order to suggest the best index to be used in this region. To do so, we used daily meteorological data (temperature, precipitation and relative humidity) and registration data of forest fire occurrences in a period of three years (2010 - 2012). Meteorological data were provided by the Mozambican Agricultural Research Institute of Mozambique in Lichinga (IIAM-Lichinga), whereas the data base of fire occurrence record was provided by the Center for Monitoring and Control of Forest Fires (CCMIF) of the company Chikweti Forest of Niassa After that Then, fire danger indexes and the degree of daily danger were calculated for both indexes, where it was observed the predominance of very high degree of danger in almost every year, with a percentage of 52.65% for the FMA and 37.96% for Nesterov index. Along with values of Skill Score (SS) of 0.11 Percent Success (PS) of 44.82%, Nesterov index showed best performance for this region unlike FMA, that presented a weak performance with values of 0, 07 of SS and 35.62%of PS.

SUMMARY Prader-Willi syndrome (PWS) is a genetic disorder frequently characterized by obesity, growth hormone deficiency, genital abnormalities, and hypogonadotropic hypogonadism. Incomplete or delayed pubertal development as well as premature adrenarche are usually found in PWS, whereas central precocious puberty (CPP) is very rare. This study aimed to report the clinical and biochemical follow-up of a PWS boy with CPP and to discuss the management of pubertal growth. By the age of 6, he had obesity, short stature, and many clinical criteria of PWS diagnosis, which was confirmed by DNA methylation test. Therapy with recombinant human growth hormone (rhGH) replacement (0.15 IU/kg/day) was started. Later, he presented psychomotor agitation, aggressive behavior, and increased testicular volume. Laboratory analyses were consistent with the diagnosis of CPP (gonadorelin-stimulated LH peak 15.8 IU/L, testosterone 54.7 ng/dL). The patient was then treated with gonadotropin-releasing hormone analog (GnRHa). Hypothalamic dysfunctions have been implicated in hormonal disturbances related to pubertal development, but no morphologic abnormalities were detected in the present case. Additional methylation analysis (MS-MLPA) of the chromosome 15q11 locus confirmed PWS diagnosis. We presented the fifth case of CPP in a genetically-confirmed PWS male. Combined therapy with GnRHa and rhGH may be beneficial in this rare condition of precocious pubertal development in PWS.

RESUMO Objetivo: Apresentar o resultado da adaptação de uma gama câmara clínica para uso dedicado na obtenção de imagens tomográficas in vivo de órgãos de pequenos animais de experimentação, e de sua aplicação na obtenção de imagens cardíacas, renais e neurológicas. Métodos: Foi construída uma versão atualizada do dispositivo de adaptação miniSPECT, composto por três subsistemas: mecânico, eletrônico e de software. O dispositivo foi montado em uma câmara Discovery VH da General Electric Healthcare, retirada do serviço clínico e instalada no Centro de Imagem Pré-Clínica do Hospital Israelita Albert Einstein. O sistema combinado foi caracterizado, determinando parâmetros de funcionamento como resolução espacial, magnificação, limites de tamanho dos alvos de estudo, número de projeções, tempo de registro e tempo de reconstrução das imagens tomográficas. Resultados: Foram obtidas imagens com resolução espacial de até 0,5mm, com tempos de registro e reconstrução de 30 a 45 minutos, utilizando reconstrução iterativa com 10 a 20 iterações e 4 subconjuntos de projeções. O sistema foi validado obtendo imagens tomográficas in vivo do coração, dos rins e do cérebro de animais normais (camundongos e ratos adultos), utilizando os radiofármacos hexaquis-2-metoxi-isobutil-isonitrila marcado com 99mTc (Sestamibi-99mTc), ácido dimercaptosuccínico marcado com 99mTc (DMSA-99mTc) e hexametil-propileno-amina-oxima marcada com 99mTc (HMPAO-99mTc). Conclusão: Este tipo de aplicação, que consiste na adaptação para um objetivo alternativo de instrumentação já existente, constituiu-se em uma opção de infraestrutura de baixo custo, que permite realizar estudos in vivo em larga escala, com qualidade aprimorada, em áreas diversas, como neurologia, nefrologia, cardiologia, entre outras.

ABSTRACT Objective: To present the result of upgrading a clinical gamma-camera to be used to obtain in vivo tomographic images of small animal organs, and its application to register cardiac, renal and neurological images. Methods: An updated version of the miniSPECT upgrading device was built, which is composed of mechanical, electronic and software subsystems. The device was attached to a Discovery VH (General Electric Healthcare) gamma-camera, which was retired from the clinical service and installed at the Centro de Imagem Pré-Clínica of the Hospital Israelita Albert Einstein. The combined system was characterized, determining operational parameters, such as spatial resolution, magnification, maximum acceptable target size, number of projections, and acquisition and reconstruction times. Results: Images were obtained with 0.5mm spatial resolution, with acquisition and reconstruction times between 30 and 45 minutes, using iterative reconstruction with 10 to 20 iterations and 4 projection subsets. The system was validated acquiring in vivo tomographic images of the heart, kidneys and brain of normal animals (mice and adult rats), using the radiopharmaceuticals technetium-labeled hexakis-2-methoxy-isobutyl isonitrile (99mTc-Sestamibi), technetium-labeled dimercaptosuccinic acid (99mTc-DMSA) and technetium-labeled hexamethyl propyleneamine oxime (99mTc-HMPAO). Conclusion: This kind of application, which consists in the adaptation for an alternative objective of already existing instrumentation, resulted in a low-cost infrastructure option, allowing to carry out large scale in vivo studies with enhanced quality in several areas, such as neurology, nephrology, cardiology, among others.

RESUMO: Foi realizado um inquérito epidemiológico objetivando determinar a ocorrência de anticorpos anti-Leptospira e elencar os fatores de risco em equinos da microrregião do Pajeú, estado de Pernambuco. Foram examinados 100 soros de equinos provenientes de 38 propriedades de 4 municípios da região, pela prova de soroaglutinação microscópica (SAM), utilizando 24 sorovares de Leptospira spp. como antígeno. Das 100 amostras testadas, 28 (28%) foram reagentes. Os sorovares mais frequentes foram Patoc (35,71%), Butembo (32,14%) e Sentot (14,30%). O uso de pasto como volumoso (odds ratio =7,80; intervalo de confiança de 95% - IC95% 1,71-35,50; p=0,008) foi identificado como fator de risco. Sugere-se a necessidade de estudos acerca do isolamento do agente e da caracterização de sua patogenicidade, bem como se recomenda o controle de roedores em depósitos de ração e no ambiente.

ABSTRACT: An epidemiological survey aiming to determine the occurrence of anti-Leptospira antibodies and to identify risk factors was carried out in horses of the Pajeú microregion, state of Pernambuco. Sera from 100 horses from 38 properties in four counties in the region were examined by the microscopic agglutination test (MAT), using 24 Leptospira spp. serovars as antigens. Of the 100 samples tested, 28 (28%) were positive. Most prevalent serovars were Patoc (35.71%), Butembo (32.14%) and Sentot (14.30%). Supply of pasture as forage (odds ratio =7.80; 95% confidence interval - 95%CI 1.71-35.50; p=0.008) was identify as risk factor. It is suggested the need for studies on agent isolation and characterization of its pathogenicity, as well as it is recommended the rodent control in deposits of feed and environment.
