RESUMO: A fasciolose bovina é uma zoonose parasitária negligenciada que resulta em perdas econômicas para a cadeia produtiva da carne devido à condenação de fígado em abatedouros-frigoríficos. Essa doença é descrita em diversas áreas do Brasil, mas existe uma deficiência de informações atuais sobre a prevalência nos estados do Rio de Janeiro e Espírito Santo. Essa nota descreve a prevalência de fasciolose de 2018 a 2021 de acordo com o município de origem e o impacto econômico devido à condenação de fígados em um abatedouro que recebe animais de ambos os estados. A prevalência no Estado do Espírito Santo (10,4%) foi significativamente maior do que no Rio de Janeiro (3,6%) (P < 0,01) e resultou em uma perda econômica de R$ 64.636,00. Os municípios de Vargem Alta, Anchieta, Cachoeiro do Itapemirim, Castelo, Atilio Vivacqua, Apiacá e Ibitirama apresentaram prevalência superior à prevalência desse estudo (10,3%), sendo que esses municípios vem sendo reconhecidos como áreas de alto risco. Apesar de uma aparente redução na prevalência da enfermidade, a fasciolose persiste como uma causa de perdas econômicas aos abatedouros, especialmente no Estado do Espírito Santo, e medidas profiláticas ainda precisam ser adotadas nas fazendas.

ABSTRACT: Bovine fasciolosis is a neglected parasitic zoonosis that causes economic losses to beef production chains due to liver condemnation at abattoirs. Despite the characterization of Bovine fasciolosis in several areas of Brazil, an update on its prevalence in the states of Rio de Janeiro and Espirito Santo is lacking. Thus, fasciolosis prevalence from 2018 to 2021 is presented here according to cattle origin (municipalities of both states). In addition, the associated economic impact on an abbatoir was analyzed through liver condemnation of bovines from both states. The prevalence of fasciolosis in the state of Espírito Santo (10.4%) was significantly higher than Rio de Janeiro (3.6%) (P < 0.01), and resulted in an economic loss of US$12,678.60 for the abattoir. The following municipalities located in the state of Espírito Santo presented prevalences above the mean (10.3%) established in the study: Vargem Alta, Anchieta, Cachoeiro do Itapemirim, Castelo, Atilio Vivacqua, Apiacá and Ibitirama. Thus, majority of these municipalities are considered high-risk areas. Although, there is an aparrent reduction of fasciolosis prevalence, it continues to be a cause of economic losses in abattoirs especially in the state of Espírito Santo. Accordingly, prophylactic measures must still be adopted in cattle farms.

Abstract Using a local atmospheric electric field sensor network (Field Mill), an electromagnetic link model was proposed considering a free space electric field and a theoretical electric field calculated from an atmospheric discharge. With this, it was possible to compare the theoretical value of this electric field with the experimental value of the local atmospheric electric field (estimated by the Field Mill sensor network). The results are initially analyzed considering wavelengths in the EHF spectrum (λ ~ 10-5m) and the VLF spectrum (λ ~ 104m). As assumed before, admitting that the lightning channel acts as an isotropic irradiator and a Field Mill sensor acts as a receiving antenna for the spectrum emitted by the lightning, a irradiated power model of the electromagnetic waves reaching the Field Mill sensor, according to the ITU-R P.873.4 standard, was calculated, thus allowing a correlation with a satellite radio link, in which the Field Mill sensor acts as a ground receiving antenna and the main channel of the lightning strikes acts as a transmitting antenna. Also, a model of the power irradiated by each lightning discharge, recorded by the Field Mill sensor network, was proposed, and the Equivalent Isotropically Radiated Power - EIRP was calculated for different values of effective electric field (Eef) and then compared with the model of the power irradiated by the antenna (lightning). This makes it possible to do an analysis and determine if the lightning discharge can be approximated to an isotropically irradiated antenna model.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the correlation between P-wave indexes, echocardiographic parameters, and CHA2DS2-VASc score in patients without atrial fibrillation and valvular disease. METHODS: This retrospective cross-sectional study included patients of a tertiary hospital with no history of atrial fibrillation, atrial flutter, or valve disease and collected data from June 2021 to May 2022. The exclusion criteria were as follows: unavailable medical records, pacemaker carriers, absence of echocardiogram report, or uninterpretable ECG. Clinical, electrocardiographic [i.e., P-wave duration, amplitude, dispersion, variability, maximum, minimum, and P-wave voltage in lead I, Morris index, PR interval, P/PR ratio, and P-wave peak time], and echocardiographic data [i.e., left atrium and left ventricle size, left ventricle ejection fraction, left ventricle mass, and left ventricle indexed mass] from 272 patients were analyzed. RESULTS: PR interval (RHO=0.13, p=0.032), left atrium (RHO=0.301, p<0.001) and left ventricle diameter (RHO=0.197, p=0.001), left ventricle mass (RHO=0.261, p<0.001), and left ventricle indexed mass (RHO=0.340, p<0.001) were positively associated with CHA2DS2-VASc score, whereas P-wave amplitude (RHO=-0.141, p=0.02), P-wave voltage in lead I (RHO=-0.191, p=0.002), and left ventricle ejection fraction (RHO=-0.344, p<0.001) were negatively associated with the same score. The presence of the Morris index was associated with high CHA2DS2-VASc (p=0.022). CONCLUSION: Prolonged PR interval, Morris index, increased left atrium diameter, left ventricle diameter, left ventricle mass, and left ventricle indexed mass values as well as lower P-wave amplitude, P-wave voltage in lead I, and left ventricle ejection fraction values were correlated with higher CHA2DS2-VASc scores.

ABSTRACT Introduction: Portal hypertension still represents an important health problem worldwide. In the search for knowledge regarding this syndrome, experimental studies with animal models have proven to be useful to point the direction to be taken in future randomized clinical trials. Purpose: To validate the experimental model of portal hypertension and esophagogastric varices in a medium-sized animal. Methods: This study included five minipigs br1. Midline laparotomy with dissection of the portal vein and production of a calibrated stenosis of this vein was performed. Measurement of pressure in the portal venous and digestive endoscopic were performed before and five weeks after the production of a stenosis. Results: All animals were 8 months old, average weight of 17 ± 2.5 kg. The mean pressure of the portal vein immediately before the partial ligation of the portal vein was 8.9 + 1.6 mm Hg, with 26.6 + 5.4 mm Hg in the second measurement five weeks later (p < 0.05). No gastroesophageal varices or hypertensive portal gastropathy were seen at endoscopy procedures in our sample at any time in the study. Conclusion: Portal vein ligation in minipigs has been validated in the production of portal hypertension, but not in the formation of esophageal varices.

RESUMO: A cisticercose bovina (CB) é uma doença importante no Brasil devido à sua detecção em abatedouros-frigoríficos que resulta em impactos econômicos aos criadores de bovinos, e um problema de saúde pública. Apesar da sua importância, o conhecimento sobre a sua epidemiologia e impacto persiste não completamente descritos em diversas áreas do país requer mais estudos. Portanto, esse estudo objetivou estabelecer a prevalência nos municípios e regiões do Estado do Espírito Santo de 2017 a 2019; estabelecer os fatores de risco associados; e estimar o impacto econômico aos pecuaristas. Durante o período, 2.330 casos de BC foram dectados entre os 407.529 bovinos inspecionados sob regime de inspeção federal (0,57%; I.C. 95% 0,55 - 0,60%), com maior frequência de cisticercos inviáveis (66,14%). Os pecuaristas perderam pelo menos US$153.000,20 devido à ocorrência de CB durante o período. As áreas de maior risco para a enfermidade nesse estado estão nas mesoregiões Metropolitana (OR = 9,19), Litoral Sul (OR = 7,77), Caparó (OR = 7,44), e Central Sul (OR = 7,19), respectivamente. A doença foi detectada em animais de 67 municípios e a prevalência da enfermidade foi maior em áreas com elevada densidade populacional humana (OR = 1,58; p = 0,01). Assim, conclui-se que a CB é uma importante doença para a cadeia da carne bovina no estado, além de uma importante causa de perdas econômicas, principalmente em algumas áreas, e necessita, urgentemente, da adoação de medidas profiláticas para reduzir a ocorrência desse parasita.

ABSTRACT: Bovine cysticercosis (BCC) is an important disease in Brazil due to its detection in abattoirs, resulting in economic losses for cattle farmers, and a public health corcern. Besides its importance, the knowledge about BCC epidemiology and impact remains not fully described in several areas in this country, requiring more studies. Thus, this study focused on establishing BCC prevalence in the regions and municipalities of the state of Espírito Santo from 2017 to 2019, establishing the associated risk factors, and estimating the economic losses for cattle farmers. A set of 2,330 cases of BCC was detected in the 407,529 bovine inspected by Federal Inspection Service (0.57%; C.I. 95% 0.55 - 0.60%) with a higher detection of unviable cysticercus (66.14%). The beef producers lost at least US$153,000.20 due to BCC through this period. The highest risk for BCC infection occurred in Metropolitana (OR = 9.19), Litoral Sul (OR = 7.77), Caparó (OR = 7.44), and Central Sul (OR = 7.19) mesoregions, respectively. The BCC was detected in animals from 67 municipalities and its prevalence increased in areas with high human population density (OR = 1.58;; p = 0.01). In conclusion, BCC is an important disease for beef production chain in the Brazilian state of Espírito Santo and a cause of economic losses, mainly in some areas, and urgently requires the adoption of prophylactic strategies to reduce the ocurrence of this parasite.

Abstract: The global atmospheric electric circuit is based on a model of electrical connection between the earth and the ionosphere (waveguide), capable of representing the flow of electric current in this waveguide. In the proposed model, a storm acts as a generator, allowing the ionosphere to maintain its highest electrical potential (approximately 300kV) in relation to Earth. When a storm forms, the bottom of the cloud becomes negatively charged. This study is focused on modeling this specific part of the global atmospheric electric circuit, which is renamed local atmospheric electric circuit. In the methodology, we use an RLC circuit to calculate the effects of electrified clouds in a 375kV transmission line considering an electrical coupling between them (an RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and to capacitor (C). The mathematical formulation was developed using transmission line theory considering a connection with the top of the storm cloud. Then, a model simulation using GNU Octave was performed, and the results demonstrated how this coupling affects voltage drop and phase shift in a 375kV transmission line. Thus, a local atmospheric electric circuit model, considering the particularities of the environment immersed in a real transmission line model, configures an important model in the perspective of project management of electric energy transmission networks.

Resumo No atual contexto da epidemia de HIV múltiplas estratégias de prevenção vêm se apresentando como alternativas para populações mais suscetíveis, incluindo as biomédicas. Este trabalho buscou compreender as percepções de risco ao HIV de homossexuais e bissexuais e a experiência de uso da Profilaxia Pós-Exposição sexual ao HIV (PEP Sexual). Trata-se de estudo de abordagem qualitativa com uso de entrevistas semiestruturadas com 25 participantes em cinco cidades brasileiras. Os resultados apontam que dada a proeminência do preservativo como estratégia de prevenção ao HIV/Aids, a falha do método, o uso não consistente e o não uso intencional constituem as referências centrais da percepção de risco e a consequente tomada de decisão de busca por PEP. Quanto às percepções e os significados do uso da PEP, estes são modulados pelo conhecimento prévio sobre o método. O trabalho amplia o debate sobre aspectos subjetivos envolvendo a prevenção do HIV entre HSH, especialmente no que concerne a percepção de risco e tomada de decisão para o uso da PEP no atual cenário da epidemia e no contexto da prevenção combinada.

Abstract In the current context of the HIV epidemic, multiple prevention strategies including biomedical interventions have been presented as alternatives for vulnerable groups. This study investigated homosexuals’ and bisexuals’ perceptions of the risk of HIV infection and their experiences of using HIV post-exposure prophylaxis (PEP). We conducted a qualitative study with 25 men who have sex with men (MSM) in five Brazilian cities using semi-structured interviews. The results showed that the use of condoms was the main HIV prevention strategy employed by the respondents. In addition, condom failure, inconsistent condom use and intentional non-use are the main prompters of risk perception and the consequent decision to seek PEP. The respondent’s perceptions and meanings of the use of PEP were mediated by prior knowledge of PEP. This work broadens the debate on the more subjective aspects of HIV prevention among MSM, especially those related to risk perception and the decision to use PEP in the context of combined prevention.

RESUMO OBJETIVO: Avaliar a tendência temporal da incidência da tuberculose após a implementação do teste rápido molecular, identificar se a tuberculose apresenta variação sazonal e classificar o território de acordo com a densidade de casos e as áreas de risco em Macapá-AP. MÉTODOS: Estudo ecológico composto por casos de tuberculose registrados no SINAN entre 2001 e 2017. Foi utilizado o teste Prais-Winsten para classificar a tendência temporal da incidência e a Série Temporal Interrompida para identificar mudanças na tendência temporal antes e depois da implementação do teste rápido molecular, além de verificar a sazonalidade no município. Utilizou-se o estimador de Kernel para classificar a densidade de casos e estatística de varredura para identificar áreas de risco da tuberculose. RESULTADOS: Foram identificados 1730 casos, observando-se que a tendência temporal da incidência de tuberculose foi decrescente (-0,27% por mês, IC95% −0,13 a −0,41). Não houve mudança de nível na série temporal após a implantação do teste molecular GeneXpert® MTB/RIF, porém, o período pós teste foi classificado como crescente em termos da incidência (+2,09% por mês, IC95% 0,92 a 3,27). Quanto à variação sazonal, apresentou crescimento (+13,7%/mês, IC95% 4,71 a 23,87) nos meses de dezembro a junho, referente ao período de chuvas – chamado inverno amazônico – e decréscimo (-9,21% por mês, IC95% −1,37 a −16,63) nos demais períodos. Por meio de Kernel, foram classificadas áreas com alta densidade de casos nos distritos Central e Norte e, com a estatística de varredura, foram identificados três aglomerados de proteção, AE1 (RR = 0,07), AE2 (RR = 0,23) e AE3 (RR = 0,36), e um aglomerado de alto risco, AE4 (RR = 1,47). CONCLUSÃO: A tendência temporal da incidência de tuberculose se revelou decrescente na série temporal, todavia, um crescimento na detecção foi observado após introdução do TRM-TB, e ainda se evidenciou que há comportamento sazonal da tuberculose. A distribuição dos casos foi heterogênea, com tendência de concentração em territórios vulneráveis e de risco, evidenciando um padrão de desigualdade da doença no território.

ABSTRACT OBJECTIVE: To evaluate the temporal trend of tuberculosis incidence after the implementation of the rapid molecular test (RMT-TB), to identify whether tuberculosis presents seasonal variation and to classify the territory according to case density and risk areas in Macapá, Amapá. METHODS: Ecological study of tuberculosis cases registered in the Sistema de Informação de Agravos de Notificação (SINAN – Information System for Notifiable Diseases) between 2001 and 2017. We used the Prais-Winsten test to classify the temporal trend of incidence and the interrupted time series to identify changes in the temporal trend before and after the implementation of the rapid molecular test, and to verify seasonality in the municipality. The Kernel estimator was used to classify case density and scan statistics to identify areas of tuberculosis risk. RESULTS: A total of 1,730 cases were identified, with a decreasing temporal trend of tuberculosis incidence (−0.27% per month, 95%CI −0.13 to −0.41). The time series showed no change in level after the implementation of the GeneXpert®MTB/RIF molecular test; however, the incidence increased in the post-test period (+2.09% per month, 95%CI 0.92 to 3.27). Regarding the seasonal variation, it showed growth (+13.7%/month, 95%CI 4.71 to 23.87) from December to June, the rainy season – called amazon winter season –, and decrease (−9.21% per month, CI95% −1.37 to −16.63) in the other periods. We classified areas with high density of cases in the Central and Northern districts using Kernel and identified three protection clusters, SC1 (RR = 0.07), SC2 (RR = 0.23) and SC3 (RR = 0.36), and a high-risk cluster, SC4 (RR = 1.47), with the scan statistics. CONCLUSION: The temporal trend of tuberculosis incidence was decreasing in the time series; however, detection increased after the introduction of RMT-TB, and tuberculosis showed seasonal behavior. The case distribution was heterogeneous, with a tendency to concentrate in vulnerable and risk territories, evidencing a pattern of disease inequality in the territory.

Abstract During the last year the Group of Atmospheric Electricity Phenomena (FEA/UFPR) developed a short range lightning location network based on a sensor device called Storm Detector Network (SDN), along with a set of algorithms that enables to track storms, determining the Wide Area Probability (WAP) of lightning occurrence, risk level of lightning and Density Extension of the Flashes (DEF), using the geo-located lightning information as input data. These algorithms compose a Dashboard called Tracking Storm Interface (TSI), which is the visualization tool for an experimental short range Storm Detector network prototype in use on the region of Curitiba-Paraná, Brazil. The algorithms make use of Geopandas and clustering algorithms to locate storms, estimate centroids, determine dynamic storm displacement and compute parameters of thunderstorms like velocity, head edge of electrified cloud, Mean Stroke Rate, and tracking information, which are important parameters to improve the alert system which is subject of this research. To validate these algorithms we made use of a simple storm simulation, which enabled to test the system with huge amounts of data. We found that, for long duration storms, the tracking results, velocity and directions of the storms are coherent with the values of simulation and can be used to improve an alert system for the Storm Detector network. WAP can reach at least 75% of prediction efficiency when used 6 past WAP data, but can reach 98.86% efficiency when more data is available. We use storm dynamics to make improved alert predictions, reaching an efficiency of ~87%.

Resumen Antes de que se disponga de una vacuna contra el SARS-CoV-2, son necesarias varias medidas para controlar la pandemia de COVID-19. En forma análoga, en ausencia de una vacuna disponible, los Programas de Prevención del VIH combinados han consolidado una gran experiencia de intervenciones biomédicas, conductuales y estructurales adecuadas para varios entornos epidemiológicos. La adaptación de estas experiencias puede organizar respuestas a mediano y largo plazo para hacer frente a la epidemia de COVID-19.

Abstract Before a vaccine against SARS-CoV-2 became available, several measures to control COVID-19 pandemic are necessary. Analogously, in the absence of an available vaccine, Combination HIV Prevention Programmes have consolidated a large experience of biomedical, behavioral and structural interventions suitable for several epidemiological settings. Adaptation of such experiences can organize mid-term and long-term responses to face COVID-19.
