SUMMARY OBJECTIVE: The aim of this study was to investigate whether the degree of urbanization influences the prevalence of chronic kidney disease in Brazilian indigenous people. METHODS: This is a cross-sectional study conducted between 2016 and 2017 in northeastern Brazil and includes individuals aged between 30 and 70 years from two specific indigenous groups who volunteered to participate in the study: the Fulni-ô people (lowest degree of urbanization) and the Truká group (greater degree of urbanization). Cultural and geographical parameters were used to characterize and measure the magnitude of urbanization. We excluded individuals with known cardiovascular disease or renal failure who required hemodialysis. Chronic kidney disease was defined as a single measurement of an estimated glomerular filtration rate <60 mL/min/1.73 m2 using the Chronic Kidney Disease Epidemiology Collaboration creatinine equation. RESULTS: A total of 184 indigenous people from the Fulni-ô group and 96 from the Truká group with a median age of 46 years (interquartile range: 15.2) were included. We found a chronic kidney disease rate of 4.3% in the total indigenous population, generally affecting an older population: 41.7% over 60 years old (p<0.001). The Truká people had a chronic kidney disease prevalence of 6.2%, with no differences in kidney dysfunction across age groups. The Fulni-ô participants had a chronic kidney disease prevalence of 3.3%, with a higher proportion of kidney dysfunction in older participants (of the six Fulni-ô indigenous people with chronic kidney disease, five were older). CONCLUSION: Our results suggest that a higher degree of urbanization seems to negatively influence the prevalence of chronic kidney disease in Brazilian indigenous people.

Abstract: Understanding what motivates the tourist to visit theme parks can help in the development of strategies for organizations working in the field of leisure, entertainment and tourism. The objective is to identify the motivators and determinants of the consumer's intention to visit theme parks. Through an online survey, data was collected from 260 participants and these data are analyzed through multiple regression. In general, the results showed that, of the constructs proposed in the theoretical model, where both motivational factors and determining factors exert a positive influence on the intention to visit, even if, in certain cases, the motivational factors will exert an even greater force on the outcome. It also indicated that, although the literature of consumer behavior brings the consumption of theme parks as a type of hedonic consumption, we can analyze a rational characteristic in the determining factors, which highlighted the importance of price in the process of intention to visit. From a theoretical point of view, the contribution of this research stems from the investigation of a still unheard of context in the literature of tourist consumer behavior, bringing a new view of the probable intention to visit of the consumer who has a certain propensity to acquire this type of service. In practice, it can help managers understand which attributes are most important to their potential customers in their decision-making.

Abstract Cervical cancer is a leading cause of death among women. The endocervical adenocarcinoma (ECA) represents an aggressive and metastatic type of cancer with no effective treatment options currently available. We evaluated the antitumoral and anti-migratory effects of hypericin (HYP) encapsulated on Pluronic F127 (F127/HYP) photodynamic therapy (PDT) against a human cell line derived from invasive cervical adenocarcinoma (HeLa) compared to a human epithelial cell line (HaCaT). The phototoxicity and cytotoxicity of F127/HYP were evaluated by the following assays: colorimetric assay, MTT, cellular morphological changes by microscopy and long-term cytotoxicity by clonogenic assay. In addition, we performed fluorescence microscopy to analyze cell uptake and subcellular distribution of F127/HYP, cell death pathway and reactive oxygen species (ROS) production. The PDT mechanism was determined with sodium azide and D-mannitol and cell migration by wound-healing assay. The treatment with F127/HYP promoted a phototoxic result in the HeLa cells in a dose-dependent and selective form. Internalization of F127/HYP was observed mainly in the mitochondria, causing cell death by necrosis and ROS production especially by the type II PDT mechanism. Furthermore, F127/HYP reduced the long-term proliferation and migration capacity of HeLa cells. Overall, our results indicate a potentially application of F127/HYP micelles as a novel approach for PDT with HYP delivery to more specifically treat ECA. women ECA (ECA available antimigratory anti migratory (HYP F F12 F127HYP FHYP (F127/HYP (PDT (HeLa HaCaT.

ABSTRACT In 2022, Salvador and co-authors published an up-to-date list of gastropod species recorded from Brazilian caves. That list included 18 species (15 land and three freshwater species) that were considered by the authors to be restricted to caves (troglobitic). In this contribution we argue that only six of the species listed by them as truly troglobites can be classified in that category. We disagree with some characteristics listed by Salvador and co-authors to diagnose the species they classify as cave-restricted and argue that those species do not have truly troglomorphic traits (characteristic of subterranean habitats). Since the Brazilian legislation considers the degree of association with caves as a decisive attribute to preserve them, it is important to clarify the characteristics are sufficient and necessary for a species to be classified as cave-dependent. 2022 coauthors co uptodate up date 1 15 (1 troglobitic. troglobitic .

RESUMO Condições climáticas e parâmetros operacionais dos pulverizadores influenciam a qualidade da pulverização. Os veículos aéreos não tripulados são considerados uma ferramenta tecnológica moderna, útil e bastante eficiente na aplicação de defensivos agrícolas, uma vez que realizam pulverizações pontuais, reduzindo problemas ambientais e de saúde pública. O objetivo deste estudo foi caracterizar a qualidade da pulverização realizada com um veículo aéreo não tripulado em função da altura de voo e a posição do alvo em lavoura de café de região montanhosa. Utilizou-se três alturas de voo (2,5; 3,0; e 4,0 m) e os alvos foram colocados na parte inferior e superior da planta. Em cada planta utilizou-se 12 etiquetas de papel hidrossensível no total, seis para a parte inferior e seis para a parte superior. O software CIR 1.5 foi aplicado para determinar a porcentagem de cobertura, densidade de gotas, diâmetro da mediana volumétrica, diâmetro correspondente a 10 e 90% do volume, diâmetro mediano numérico e amplitude relativa. Os resultados mostraram que a altura de voo apenas influenciou os parâmetros diâmetro volumétrico que corresponde a 10% do volume, diâmetro mediano numérico e porcentagem de cobertura. A posição do alvo no dossel influenciou todos os parâmetros de pulverização estudados. No café de montanha, o sistema de pulverização por veículo aéreo não tripulado é mais eficiente para a parte inferior da planta.

ABSTRACT Weather conditions and sprayer operating parameters influence spray quality. Unmanned aerial vehicles are considered a modern, useful, and very efficient technological tool in the application of pesticides, as they carry out punctual spraying, and reduce environmental and public health problems. The objective of this study was to characterize the spraying quality carried out with an unmanned aerial vehicle as a function of flight height and target position in a coffee plantation in a mountainous region. Three flight heights (2.5, 3.0, and 4.0 m) were used, and the targets were placed at the top and bottom of the plant. For each plant, six water sensitive papers were placed on top of the plant and six were placed at the bottom. CIR 1.5 software was applied to determine the coverage percentage, drop density, volume median diameter, volumetric diameter corresponding to 10 and 90%, numerical median diameter, and relative amplitude. The results showed that the flight height only influenced the parameters of the volumetric diameter corresponding to 10% of the volume, numerical median diameter, and coverage percentage. The target position on the canopy influenced all the evaluated spraying parameters. In mountainous coffee plantations, the spraying system using unmanned aerial vehicle spraying is more efficient for the lower part of the plant.

Resumo A estabilidade dos flocos de jabuticaba produzidos por drum drying usando fécula de mandioca foi avaliada. Isotermas de sorção a 25 °C foram determinadas e as amostras foram armazenadas sob condições controladas (umidade relativa = 60% e temperatura = 20, 25 e 35 °C) até 235 dias. O teor de anticianinas e os parâmetros de cor (L*, a* e b*) foram monitorados. O modelo de GAB teve o melhor ajuste das isotermas de sorção, com um teor de umidade da monocamada de 0,1596 g água/g base seca. A avaliação visual das amostras não mostrou aglomeração e escurecimento para aw ≤ 0,33 a 25 °C, o que pode ser considerado o ponto crítico. A degradação de antocianinas e dos parâmetros de cor seguiu uma cinética de ordem zero e primeira ordem, respectivamente. Os tempos de meia vida (630 a 1450 dias) apresentaram boa estabilidade a 25 °C, enquanto que os valores do fator de aceleração das reações com a temperatura (2,2 ≤ Q10 ≤ 3,2) e a energia de ativação (15 ≤ Ea ≤ 19 kcal/mol) demonstraram uma alta sensibilidade do produto com a temperatura.

Abstract The stability of jabuticaba flakes produced by drum drying using cassava starch as additive was evaluated. Sorption isotherms at 25 ºC were determined. Samples were stored under controlled conditions (relative humidity = 60%, temperature = 20, 25 and 35 ºC) for until 235 days. The anthocyanin content and color parameters (L*, a* and b*) were monitored. GAB model led to the best adjustment of sorption isotherm, with a monolayer moisture value of 0.1596 g water/g dry basis. The visual observations did not point out agglomerations and darkening at aw values higher than 0.33 at 25 ºC, which can be considered the critical point. The degradation of anthocyanin and color parameters followed first and zero-order kinetic model, respectively. The half-life times (630 to 1450 days) showed good stability at 25 ºC, while the temperature acceleration coefficient (2.2 ≤ Q10 ≤ 3.2) and activation energy (15 ≤ Ea ≤ 19 kcal/mol) values demonstrated a high-temperature sensitivity.

ABSTRACT This review provides a general overview on the positivity and persistence of Zika virus (ZIKV) in female genital tract (FGT) of non-pregnant women and animals, as well as in cell cultures, and its influence on FGT health. We performed a systematic review based on the PRISMA statement to identify studies focused on “Zika virus” and “non-pregnant female” in PubMed, Embase, Scopus Scholar and Web of Knowledge databases of full-text papers and abstracts published in English, with no restrictions regarding the initial date of publication, up to August 2019. Our search terms yielded 625 records, that were 108 after removal of duplicates, leaving 517 items for title and abstract reviews. Of these, 475 did not meet the inclusion criteria, leaving 42 records for full-text review and resulting in the exclusion of 6 additional records. The remaining 36 met our inclusion criteria. Variations were observed regarding the presence and persistence of ZIKV in lower and upper genital samples. However, the FGT was the place in which ZIKV RNA has been detected, sometimes for relatively long periods, even after the clearance from blood and urine. In addition to the vagina and cervix, the endometrium, uterus and ovary (oocytes and follicles) could also be involved in persistent ZIKV infections. Further prospective studies are needed to assess the effect of ZIKV on FGT health.

Measles is a human infectious disease of global concern that is caused by the measles virus. In this study, we report the complete genome sequencing of one measles virus isolate, genotype D8, that was obtained directly from a urine sample in Boa Vista city, the capital of Roraima state in Brazil. Phylogenetic reconstruction grouped the genome described in this study with that of samples from Australia, South Korea, and Italy. To our knowledge, this is the first complete genome sequence of a wild-type measles virus reported from Latin America. Therefore, the present data strengthen the current knowledge on the molecular epidemiology of measles worldwide.

ABSTRACT The larva of the whirligig beetle Enhydrus sulcatus (Wiedemann, 1821) is described and illustrated for the first time, including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages and legs. Larvae of Enhydrus Laporte, 1834 exhibit the characters traditionally recognized as autapomorphies of the family Gyrinidae: well developed cardo, completely divided prementum, presence of lateral abdominal tracheal gills, and presence of four terminal hooks on the pygopod. The egg bursters located on the parietal, the presence of an additional sensorial plate on the third antennomere, and a well developed lacinia may also represent autapomorphies of the family. Enhydrus larvae share with those of the other known Dineutini genera the presence of numerous minute additional setae on the mandible, the presence of additional setae on the cardo, the submedial position of the coxal seta CO12, the absence of the trochanteral seta TR2, and the presence of numerous pore-like additional structures on the ultimate maxillary and labial palpomeres. On the other hand, Enhydrus can be distinguished from the other known dineutine genera by the presence of pore-like additional structures on the basal maxillary and labial palpomeres, the presence of ventral spinulae on the pygopod, and the bare tracheal gills, among other characters.

Os pulverizadores costais são amplamente utilizados no setor florestal. No entanto, existem equipamentos que podem ocasionar certo grau de estresse ao operador, acarretando-lhe danos à sua saúde. Assim, objetivou-se com este trabalho avaliar, ergonomicamente, quatro pulverizadores costais (termonebulizador, pneumático motorizado, costal manual e costal elétrico) quanto aos parâmetros nível de ruído, nível de vibração de corpo inteiro, gasto energético e esforço físico. Na avaliação de ruído, utilizou-se um dosímetro 01dB, comparando os resultados com o que estabelece a Norma NR-15. Para os níveis de vibração, utilizou-se um acelerômetro triaxial, ligado a um processador de sinal do tipo Maestro, sendo os dados comparados com as Diretrizes Europeias. Já para gasto calórico e esforço físico, usaram-se um analisador de gases metabólicos fabricado pela Medgraphics® modelo VO2000 e um monitor cardíaco da marca Polar. Observou-se que o equipamento costal manual e o elétrico não apresentaram problemas quanto ao nível de ruído. Já o pulverizador pneumático e o termonebulizador exibiram valores acima do recomendado pela Norma NR-15, com níveis de 99,97 e 94,33 dB(A), respectivamente. Da mesma forma, os equipamentos motorizados tiveram níveis de vibração elevados em comparação com os demais equipamentos, com vibração global (A8) de 2,09 m s-2 para o termonebulizador e 2,15 m s-2 para o pneumático. Quanto ao gasto energético, houve pequenas variações quanto ao tipo de equipamento utilizado, com gasto variando entre 3,0 e 3,96 kcal min-1.

Knapsack sprayers have been widely used in forestry. However, some equipment may cause different levels of stress for the operators, causing harm to their health. Therefore, this study aimed to evaluate ergonomically four knapsack sprayers (thermal sprayer, pneumatic motorized, hand sprayer and electric sprayer), regarding to noise parameters, body vibration level, energy expenditure and physical effort. For noise evaluation, a dosimeter 01dB was used, and the results were compared with the regulatory norm NR-15. For vibration levels, we used a triaxial accelerometer connected to a signal processor Maestro type, and data were compared to the European directives. For caloric expenditure and physical effort, we used a gas metabolic analyzer manufactured by Medgraphics® model VO2000 and a heart monitor from Polar brand. We observed that the hand and electric knapsack sprayers did not present problems related to the noise level. However, the pneumatic motorized knapsack and the thermal sprayer, showed levels above than recommended by regulatory norm NR-15 with levels of 99.97 and 94.33 dB(A), respectively. Similarly, the motorized equipment presented high levels of vibration compared to the other equipments, with global vibration (A8) of 2.09 m s-2 for the thermal sprayer and 2.15 m s-2 for the pneumatic. Regarding to energy expenditure, there were small variations between the kind of equipment used, with expenditure ranging from 3.0 to 3.96 kcal min-1.

INTRODUÇÃO: O ultrassom intracoronário (USIC) é um método capaz de fornecer medida sensível e reprodutível das dimensões da artéria coronária, da placa aterosclerótica e do lúmen arterial. Avanços em sua tecnologia permitem agora a caracterização da composição e da morfologia das placas ateroscleróticas. Embora estudos prévios tenham reportado dados utilizando USIC com análise de radiofrequência, o uso de uma nova modalidade (iMap®, Boston Scientific, Santa Clara, Estados Unidos) de caracterização da placa aterosclerótica é muito pouco conhecida. Nosso objetivo será analisar as características morfológicas, teciduais e fenotípicas das placas ateroscleróticas consideradas angiograficamente "culpadas" e "não-culpadas" em pacientes submetidos a angiografia coronária decorrente de infarto agudo do miocárdio (IAM). MÉTODOS: Estudo prospectivo, transversal, em único centro (Hospital São Paulo - Escola Paulista de Medicina - Universidade Federal de São Paulo/UNIFESP, São Paulo, SP, Brasil). Serão selecionados 50 pacientes para análise ultrassonográfica, de acordo com os seguintes critérios de inclusão: idade < 75 anos, IAM sem supradesnivelamento do segmento ST ou IAM com supradesnivelamento do segmento ST recente, com ou sem uso de fibrinolítico prévio. CONCLUSÕES: O presente estudo objetivará a caracterização morfológica, tecidual e fenotípica da placa aterosclerótica utilizando uma nova modalidade de imagem ainda pouco estudada em pacientes com IAM.

BACKGROUND: Intravascular ultrasound (IVUS) provides a sensitive and reproducible measurement of coronary artery dimensions, atherosclerotic plaque, and arterial lumen. Advances in IVUS technology now allow the characterization of the composition and morphology of atherosclerotic plaques. Although previous studies have reported data using IVUS radiofrequency analysis, the use of a new modality (iMap®, Boston Scientific, Santa Clara, USA) of atherosclerotic plaque characterization is very little known. Our objective is to analyze the morphological, phenotypic and tissue characteristics of "culprit" and "non-culprit" atherosclerotic plaques determined by angiography in patients undergoing coronary angiography due to acute myocardial infarction (AMI). METHODS: Prospective, cross-sectional, single center study (Hospital São Paulo - Escola Paulista de Medicina - Universidade Federal de São Paulo/UNIFESP, São Paulo, SP, Brazil). Fifty patients will be selected for ultrasound analysis according to the following inclusion criteria: age < 75 years, non-ST-segment elevation AMI or recent ST-segment elevation AMI, with or without previous fribrinolytic agents. CONCLUSIONS: The present study is aimed at obtaining morphological, phenotypic and tissue characteristics of the atherosclerotic plate using an imaging modality not extensively evaluated in patients with AMI.

OBJETIVO: Pacientes submetidos à cirurgia cardíaca estão mais propensos a desenvolver plaquetopenia. A trombocitopenia induzida por heparina acomete cerca de 5% dos pacientes. O objetivo foi avaliar a importância clínica da trombocitopenia grave em pacientes no pós-operatório de cirurgia cardíaca. MÉTODOS: Estudo prospectivo observacional que incluiu os pacientes de cirurgia cardíaca com plaquetas <150.000 cel/mm³, durante as primeiras 24 h do pós-operatório. Todos os pacientes foram submetidos a avaliação pelo escore dos quatro "Ts" (trombocitopenia, uso de heparina prévia, trombose e queda de plaquetas não relacionada à heparina) e considerado como suspeita de trombocitopenia induzida pela heparina tipo II um escore > 6. A mortalidade na Unidade de Terapia Intensiva (UTI) e hospitalar, o tempo de internação, os escores de gravidade e a incidência de tromboses foram comparados em pacientes com escore e" 6 (grupo 1) e < 6 (grupo 2). RESULTADOS: Foram incluídos 120 pacientes divididos nos dois grupos, não havendo diferença entre os mesmos com relação a idade, prevalência do sexo, tempo de circulação extracorpórea e de cirurgia. Contudo, a incidência de trombose foi mais elevada nos pacientes do grupo 1 (23% vs. 0%, P<0,0001), assim como quanto maior o escore maior a mortalidade hospitalar (P<0,001). CONCLUSÕES: O escore > 6, em pacientes no pós-operatório de cirurgia cardíaca, está associado a maior incidência de trombose, assim como o maior escore está relacionado à elevada mortalidade hospitalar.

OBJECTIVE: Patients undergo to cardiac surgery have more probability to develop thrombocytopenia. The heparin induced thrombocytopenia happens in 5% of the patients. The aim from this study was to evaluate the clinical importance from the severe thrombocytopenia in postoperative cardiac surgical patients. METHODS: It was included cardiac surgical patients with platelets < 150000 cel/mm³ during firsts 24 h from postoperative. All patients underwent evaluation for four Ts score (thrombocytopenia, use preview of heparin, thrombosis and platelets decreased not related to heparin). In order to a four Ts score e" 6 was considered as suggestive of heparin induced thrombocytopenia type II. The mortality rate in intensive care (ICU) and hospital, length of stay, healthy state and incidence from thrombosis were compared in patients with score > 6 (group 1) and < 6 (group 2). RESULTS: It was include 120 patients who met the inclusions criterions. There was no difference between the groups in related to age, gender, time of cardiopulmonary bypass and surgery. However, the incidence of thrombosis was higher in group 1 (23% vs. 0%, P<0.0001), as well as the greater score is related to higher hospital mortality rate. CONCLUSION: The score > 6, in postoperative cardiac surgical patients, it is associated to higher incidence of thrombosis as well as the greater score is related to higher hospital mortality rate.

Foram registradas, na Estação Ecológica da Universidade Federal de Minas Gerais (UFMG), espécies de moscas que visitam flores para se alimentar. Asteraceae, Rhamnaceae, e Boraginaceae foram as famílias mais visitadas. Asteraceae foi a mais rica em espécies floridas, sendo também a mais visitada por famílias e espécie de moscas. A diversidade mais elevada de visitantes ocorreu em Baccharis trinervis (Lam.) (H'=1.86). As famílias de moscas mais diversas foram Syrphidae (H' = 2,07) e Bombyliidae (H' = 1,52). Os sirfídeos Ornidia obesa (L.) e Palpada furcata (Wied.) foram as espécies mais abundantes entre as visitantes. A abundância total de visitantes foi significativamente maior na estação chuvosa, quando um número maior de plantas estavam florescendo. Entretanto, um maior número de famílias visitou plantas durante a estação seca. O número de fêmeas em quatro famílias de moscas foi ligeiramente mais elevado do que o número de machos. Calliphoridae e Sarcophagidae mostraram padrões similares com relação ao número de espécie de plantas visitadas. Syrphidae foi mais generalista mas, Bombyliidae e Stratiomyidae foram relativamente mais especializadas. Muita espécies de moscas visitam flores, por isso a abundância e frequência de visitas podem indicar sua importância como polinizadores, bem como a importância das flores em sua dieta.

The species of flies that visit flowers to feed were recorded, at the Ecological Station of the Federal University of Minas Gerais (UFMG). Asteraceae, Rhamnaceae, and Boraginaceae were the most visited families. Asteraceae was the richest family and the most visited by flies families and species. The highest diversity of visiting flies was on Baccharis trinervis (Lam.) (H'=1.86). The most diverse families of Diptera were Syrphidae (H'= 2.07) and Bombyliidae (H'= 1.52). The syrphids Ornidia obesa (L.) and Palpada furcata (Wied.) were the most abundant species amongst visitors. Despite the total abundance of Diptera was significantly higher in the rainy season, when a higher number of plants were blooming, there were more families of visitors during the dry season. The number of females in four families of flies was typically slightly higher than the number of males. Calliphoridae and Sarcophagidae showed similar patterns regarding the number of plant species visited, while Syrphidae were the most generalized, and Bombyliidae and Stratiomyidae visited few plant species. Many species of Diptera visit flowers, and their abundance on plants could indicate their importance as pollinators as well the importance of flowers for their diet.
