Additionally, it achieved a Global CVI of 0.98 for validation by the target audience. In conclusion, the educational booklet emerges as a suitable and reliable resource for promoting eye heath among DES and non-syndrome women, offering significant potential for broader application in relevant populations.

First occurrence of feline sporotrichosis in a metropolitan area of Central-West Brazil.

Sporotrichosis is a neglected mycosis that affects human and animal hosts, including domestic cats. In Brazil, its most frequently diagnosed etiological agent is Sporothrix brasiliensis. Zoonotic transmission of S. brasiliensis occurs via direct contact between an infected cat and a susceptible human host. Notification of confirmed cases of feline sporotrichosis is not mandatory in Brazil. The metropolitan area of Goiania city can be considered a silent area for the occurrence of feline sporotrichosis. In this context, voluntary reporting of feline sporotrichosis cases is recommended for all healthcare professionals. This study aimed to report the first occurrence of S. brasiliensis in a cat from the metropolitan area of Goiania city. Cytopathology, mycology, thermal dimorphism and calmodulin gene amplification tests were performed. The mycological and molecular biological diagnoses corresponded to S. brasiliensis. The etiological agent of zoonotic sporotrichosis was detected in the metropolitan area of Goiania city, and therefore there is a risk of the emergence of new cases of cats infected with S. brasiliensis and the occurrence of zoonotic transmission of this fungus.

Smart cities and innovative urban management: Perspectives of integrated technological solutions in urban environments.

The increasing urbanization in a poorly planned way accentuates the imbalance between the population's needs and the organized development in urban spaces. The present study is based on the development of a situational diagnosis in the scope of a smart city, for the contextualization of potential opportunities for actions and innovation strategies in urban spaces. This article presents a literature overview covering the innovative actions developed in the scope of smart cities in scientific publications. Furthermore, the scope of the study is identifying innovation initiatives in the performance of actions and solutions for urban spaces. A literature review was developed supported by mappings, couplings, and diagrams, through the use of VOSViewer and SciMat software, and 115 articles were selected and analyzed, considering the articles based on the criterion of the coefficient of the number of citations concerning the year of publication. In the literature overview developed, it was found that the research within the scope of smart cities has been deepened over the years, with the evolution of the number of words related to the theme in the period from 2014 to 2021, as the advance in the number of publications from 2018 is noticeable, which highlights the increase in popularity regarding the topic, as well as its current relevance. The study identified thematic axes with an emphasis on technology and innovation, environment, urbanism, energy, governance, mobility, and accessibility. The results contributed by assembling innovative smart city actions and practices in an interrelated way with technology, innovation, and market-oriented constructs aimed to reach urban demands, as well as the development of innovative solutions between public institutions and business organizations to integrate urban spaces.

Eggshell translucency: its relationship with specific gravity and eggshell color and its influence on broiler egg weight loss, hatchability, and embryonic mortalities.

Eggshell quality is among the most important factors affecting hatchability in broiler breeders, and therefore several methods for its assessment are available in the poultry industry. Among them, eggshell translucency has received special attention in recent years due to its connection with ultrastructural disorganization of the shell layers. However, there is very limited data on the impact of translucency on hatching eggs and on the possible links between this trait and specific gravity (SG) or shell color. Thus, our study investigated associations and interactions between eggshell translucency, SG, and color on incubation parameters of eggs from the same breeding flock (Ross 308AP, 51 wk of age). To this end, light and dark eggs within 5 different SG categories (≥1.065, 1.070, 1.075, 1.080, and ≤1.085) were selected from 15,976 eggs, graded into 3 translucency scores, and later incubated to evaluate egg weight loss, hatchability and embryonic mortalities. In general, translucency scores were evenly distributed within SG categories (χ2 [8, N = 1,138] = 13.67, P = 0.090) and color (χ2 [2, N = 1,138] = 4.93, P = 0.084). No interactions between eggshell translucency and SG or between translucency and color were found for the analyzed variables. An interaction was observed between SG and eggshell color for the variable egg weight loss, where the light-shelled eggs, in most SG categories lost more weight throughout incubation than dark eggs. Eggshell translucency affected egg weight loss, hatchability, and embryonic mortality on 11 to 18 d of incubation, with highly translucent eggs showing the worst results. At the same time, eggs with SG lower than 1.070 displayed the greatest weight loss, lowest hatchability, and highest contamination. We found no influence of eggshell color on weight loss or hatchability, but light-shelled eggs exhibited higher late embryonic mortality. Together, these data suggest that despite its effects on certain hatching parameters, shell translucency bears no relationship to SG or color.

An impedimetric immunosensor for diagnosis of Brazilian spotted fever in blood plasma.

Brazilian spotted fever (BSF) is a serious disease of medical importance due to its rapid evolution and high lethality. The effectiveness of the treatment mainly depends on the rapid diagnosis, which is currently performed by indirect immunofluorescence and PCR tests, which require high costs and laboratory structure. In order to propose an alternative methodology, we sought to develop an impedimetric immunosensor (IM) based on the immobilization of specific IgY antibodies for IgG anti Rickettsia rickettsii, using blood plasma from capybara (Hydrochoerus hydrochaeris), for characterization, validation and applications of the ready IM. IM selectivity was observed when comparing capybara reagent IgG (IgGcr) readings with non-reagent IgG (IgGnr). A reagent IgG calibration curve was obtained, from which the limits of detection (LOD) and quantification (LOQ) of 1.3 ng mL-1 and 4.4 ng mL-1 were calculated, respectively. The accuracy tests showed that different concentrations of IgGcr showed a maximum deviation of 20.0%, with CI between 90.00% and 95.00%. Intermediate precision tests showed a relative standard deviation of 2.09% for researcher 1 and 2.61% for researcher 2, and the F test showed no significant difference between the recovery values found between the two analysts, since Fcal 1.56 < 5.05 and P-value 0.48 > 0, 05. Therefore, an impedimetric immunosensor was developed to detect anti BSF IgG in capybara blood plasma, which greatly contributes to the improvement of diagnostic tests, cost reduction and ease of execution.

Prevention, protocols, and lab capacity: lessons from a norovirus outbreak in the Algarve.

This brief report presents the findings of an epidemiological investigation into a large-scale outbreak of norovirus gastroenteritis that occurred in a hotel in Algarve, Portugal, in August 2022. A total of 244 cases were reported, primarily affecting Portuguese families, with the parents aged 40-50 years and the children aged 0-19 years. Reported symptoms included vomiting, nausea, abdominal pain, and diarrhoea. Norovirus genotype GI.3 [P3] was detected in stool samples from eight probable cases, while food samples tested negative for norovirus and common pathogenic bacteria. The investigation data collected suggest that the source of the outbreak was likely in the hotel's common areas, with subsequent person-to-person transmission in other areas. The final report emphasizes the importance of improving outbreak prevention and control measures, including the development of a foodborne outbreak investigation protocol, the establishment of an outbreak response team, and the enhancement of regional laboratory capacity.

Seroprevalence of Equine Leptospirosis in the State of Goiás, Brazil.

Leptospirosis, caused by Leptospira, is a zoonotic disease that, in horses, is linked to abortions, uveitis, and sporadic occurrences of liver and kidney disease, often resulting in significant economic losses for farmers. Research on the prevalence of leptospirosis in horses in the central-west region of Brazil has been relatively scarce. Thus, the present study aimed to determine the prevalence of leptospirosis in equine herds in the state of Goiás (Central Brazil). Blood samples were collected from 894 equids at 294 randomly selected farms divided into three different strata according to their herd characteristics. The microscopic agglutination test for the detection of anti-Leptospira agglutinins was carried out and the results showed that among the 294 sampled farms, 213 (72.9%; CI 95% 71.7-78.9) had one or more animals positive for leptospirosis, and of the 894 horses sampled, 513 (61.6%; CI 95% 54.3-69.0) were seropositive for leptospirosis. Djasiman, Icterohaemorrhagiae, and Australis were the most prevalent serogroups. The results showed a high prevalence of seropositive animals and a widespread distribution of positive farms in the state of Goiás. Thus, environmental sanitation measures and health education to prevent and control equine leptospirosis in the state are required.

The machining torch movement for the rectangular plasma sheet metal cut.

The sheet metals can be cut into rectangular or irregular pieces, where the main objective is to minimize the sheet metal's physical waste. However, the operating time, the number of movements to cut all rectangles edges, and the cutting process quality, must be considered. The objective of this research was to compare the machining torch movement behavior using optimal and alternative solutions for rectangular plasma sheet metal cuts. A bottom-left-fill heuristic and a tabu search heuristic were used to find the alternative solution, while the optimal solution was obtained with a mixed-integer linear programming. The comparison was developed considering three parameters: the total processing time, the effective distance traveled by the machining torch to cut the metal, and the movement distance traveled by the machining torch without cutting the metal. The packing layout given by alternative solutions can reduce the operational cutting processing time and the distance covered by the machining torch movement. From an economic perspective, optimal solutions are recommended when compared to alternative solutions given the lower expenses with raw material waste.

Impact of minimum distance constraints on sheet metal waste for plasma cutting.

We approached the two-dimensional rectangular strip packing problem (2D-SPP), where the main goal is to pack a given number of rectangles without any overlap to minimize the height of the strip. Real-life constraints must be considered when developing 2D-SPP algorithms to deliver solutions that will improve the cutting processes. In the 2D-SPP literature, a gap related to studies approaching constraints in real-life scenarios was identified. Therefore, the impact of real-life constraints found in the plasma cutting process in sheet metal waste was analyzed. A mathematical model from the literature was modified to obtain packing arrangements with plasma cutting constraints. The combination of size and number of rectangles, as well as strip width, was the main factor that affected the packing arrangement, limiting the allocation of rectangles and generating empty spaces. In summary, considering the sheet metal waste context, instances with smaller widths should be avoided in practical operations for high minimum distance constraint values, returning the worst packing arrangements. For low minimum distance constraint values, smaller width instances can be used in practical operations, as the packing arrangement is acceptable. Finally, this article can reduce material waste and enhance the cutting process in the sheet metal industry, by showing packing characteristics which lead to higher amounts of raw material waste.

The First Brazilian Cardiovascular Registry of Atrial Fibrillation: Primary Results of the RECALL Study.

BACKGROUND: It is estimated that atrial fibrillation (AF) affects approximately 1.5 million people in Brazil; however, epidemiological data are limited. We sought to evaluate the characteristics, treatment patterns, and clinical outcomes in patients with AF in Brazil by creating the first nationwide prospective registry. METHODS: RECALL was a multicenter, prospective registry that included and followed for 1 year 4,585 patients with AF at 89 sites across Brazil from April 2012 to August 2019. Patient characteristics, concomitant medication use, and clinical outcomes were analyzed using descriptive statistics and multivariable models. RESULTS: Of 4,585 patients enrolled, the median age was 70 (61, 78) years, 46% were women, and 53.8% had permanent AF. Only 4.4% of patients had a history of previous AF ablation and 25.2% had a previous cardioversion. The mean (SD) CHA2DS2-VASc score was 3.2 (1.6); median HAS-BLED score was 2 (2, 3). At baseline, 22% were not on anticoagulants. Of those taking anticoagulants, 62.6% were taking vitamin K antagonists and 37.4% were taking direct oral anticoagulants. The primary reasons for not using an oral anticoagulant were physician judgment (24.6%) and difficulty in controlling (14.7%) or performing (9.9%) INR. Mean (SD) TTR for the study period was 49.5% (27.5). During follow-up, the use of anticoagulants and INR in the therapeutic range increased to 87.1% and 59.1%, respectively. The rates/100 patient-years of death, hospitalization due to AF, AF ablation, cardioversion, stroke, systemic embolism, and major bleeding were 5.76 (5.12-6.47), 15.8 (14.6-17.0), 5.0 (4.4-5.7), 1.8 (1.4-2.2), 2.77 (2.32-3.32), 1.01 (0.75-1.36), and 2.21 (1.81-2.70). Older age, permanent AF, New York Heart Association class III/IV, chronic kidney disease, peripheral arterial disease, stroke, chronic obstructive pulmonary disease, and dementia were independently associated with increased mortality while the use of anticoagulant was associated with lower risk of death. CONCLUSIONS: RECALL represents the largest prospective registry of patients with AF in Latin America. Our findings highlight important gaps in treatment, which can inform clinical practice and guide future interventions to improve the care of these patients.

Percutaneous coronary intervention or medical therapy in patients with severe aortic stenosis and coronary artery disease undergoing transcatheter aortic valve implantation: a real-world analysis using data from an international network.

Patients undergoing transcatheter aortic valve implantation (TAVI) due to severe aortic stenosis have a high prevalence of coronary artery disease (CAD). As many of them have high surgical risk, CAD treatment in this group has typically been carried out with optimal medical treatment or paired with percutaneous coronary intervention (PCI). However, the best approach in this scenario is not well established. We aimed to evaluate 5-year cardiovascular outcomes in patients with aortic stenosis and chronic CAD treated with medical treatment alone compared to PCI coupled with medical therapy before or during TAVI. We used data from a large multinational electronic health record network (TriNetX). Patients aged 18 years or older with severe aortic stenosis and CAD who underwent TAVI in the last 10 years before the analysis were considered eligible. Five-year Kaplan-Meier curves and hazard ratios were calculated. We identified 19 058 patients undergoing isolated TAVI and 2277 patients undergoing TAVI and PCI. Using propensity matching scores, 2277 patients in each group were compared. The 5-year cumulative incidence of MACE was 22.92% in the isolated TAVI group, vs. 25.91% in the PCI-TAVI group. The probability of the composite primary outcome was not significantly different between the isolated TAVI group vs. the PCI-TAVI group [53.1 vs. 47.6%, adjusted hazard ratio (HR) 0.92, 95% confidence interval (CI), 0.80-1.05]. In a real-world study of patients with CAD and severe aortic stenosis, the 5-year probability of death, acute coronary syndrome and ischemic stroke did not differ between patients undergoing isolated TAVI compared to patients undergoing PCI before or during TAVI.

Tratamento percutâneo de origem anômala de coronária direita com trajeto maligno em paciente com morte súbita abortada / Percutaneous treatment of anomalous origin of the right coronary artery with malignant course in a patient with aborted sudden death

Anomalias coronarianas são menos frequentes em relação às doenças coronarianas adquiridas, como a aterosclerose, e têm sido implicadas como causa de eventos cardiovasculares. Este relato de caso descreve um achado incidental por angiografia de coronária direita anômala com origem no seio coronariano esquerdo e trajeto intra-arterial, após episódio de morte súbita abortada. A análise do Heart Team indicou como melhor tratamento a abordagem percutânea com implante de stent farmacológico em origem de coronária direita, procedimento este que foi realizado com sucesso. Este relato de caso e estudos recentes têm demonstrado que o tratamento percutâneo de anomalias coronarianas é uma opção segura para pacientes selecionados, levando em consideração quadro clínico, estudo anatômico e capacitação da equipe de hemodinâmica

Coronary anomalies are less frequent than acquired coronary diseases, such as atherosclerosis, and have been implicated as a cause of cardiovascular events. This case report describes an incidental finding on angiography of an anomalous right coronary artery with origin in the left coronary sinus and an intra-arterial course, after an episode of aborted sudden death. The Heart Team analysis indicated a percutaneous approach with drug-eluting stent implantation at the origin of the right coronary artery as the best treatment, and the procedure was successfully performed. This case report and recent studies have demonstrated percutaneous treatment of coronary anomalies is a safe option for selected patients, considering clinical presentation, anatomy study, and training of the cath lab team

Análise dos desfechos em intervenção coronária percutânea de tronco de coronária esquerda não protegido / Analysis of percutaneous coronary intervention outcomes in unprotected left main coronary artery lesions

Introdução: Lesões significativas no tronco de coronária esquerda são encontradas em aproximadamente 5% dos pacientes submetidos à coronariografia, sendo a maioria dos casos multiarteriais e com envolvimento do tronco distal. A cirurgia de revascularização do miocárdio é considerada o tratamento preferencial para lesões de tronco de coronária esquerda não protegido. No entanto, com o avanço de técnicas e a introdução dos novos stents liberadores de fármacos, a intervenção coronariana percutânea tem sido considerada estratégia viável, apresentando resultados favoráveis. O objetivo deste estudo foi analisar os desfechos em pacientes com lesões de tronco de coronária esquerda não protegido submetidos à intervenção coronariana percutânea. Métodos: Foram analisados dados eletrônicos de pacientes submetidos à intervenção coronariana percutânea entre dezembro de 2017 e janeiro de 2020 em um único centro, com o objetivo de avaliar características clínicas, angiográficas e os desfechos clínicos. Resultados: Foram incluídos 103 pacientes portadores de lesões significativas de tronco não protegido, 66% eram do sexo masculino, 88,3% eram hipertensos, e 87,4% possuíam função ventricular normal. Lesões envolvendo a bifurcação foram identificadas em 73,8% dos pacientes, 36,9% apresentavam lesões concomitantes nos três grandes vasos epicárdicos e 42,7% com escore SYNTAX intermediário (23 a 32 pontos). O sucesso angiográfico foi obtido em 100% dos casos, com quatro (3,9%) eventos cardíacos e cerebrovasculares adversos, sendo 2,9% de mortalidade. Conclusão: Os resultados hospitalares sustentam a intervenção coronariana percutânea como um procedimento seguro, de excelente resultado angiográfico e eventos cardíacos e cerebrovasculares adversos comparáveis aos da cirurgia de revascularização do miocárdio, configurando opção bastante viável em relação ao tratamento cirúrgico.

Background: Significant lesions in the left main coronary artery are found in approximately 5% of patients undergoing coronary angiography, with most cases involving multiple vessels and affecting the distal bifurcation. A coronary artery bypass graft surgery is considered the preferred treatment for unprotected left main coronary artery lesions. However, with the advancement of techniques and the introduction of new drug-eluting stents, percutaneous coronary intervention has been considered a viable strategy, with favorable results. The objective of this study was to analyze the outcomes in patients with unprotected left main coronary artery lesions undergoing percutaneous coronary intervention. Methods: Electronic data from patients undergoing percutaneous coronary intervention between December 2017 and January 2020 at a single center were analyzed to assess clinical and angiographic characteristics and clinical outcomes. Results: A total of 103 patients with significant unprotected left main coronary artery lesions were included; in that, 66% were male, 88.3% were hypertensive, and 87.4% had normal ventricular function. Lesions involving the bifurcation were identified in 73.8% of patients, 36.9% had concomitant lesions in the three major epicardial vessels, and 42.7% had an intermediate SYNTAX score (23 to 32 points). Angiographic success was achieved in 100% of cases, with four (3.9%) adverse cardiac and cerebrovascular events, with 2.9% mortality. Conclusion: Hospital results support percutaneous coronary intervention as a safe procedure, with excellent angiographic results and low rates of adverse cardiac and cerebrovascular events. We concluded that percutaneous coronary intervention is an option to coronary artery bypass graft surgery and is a very viable option for surgical treatment of unprotected left main coronary artery lesions.

Homenagem a Matheus Marim / Tribute to Matheus Marim

Antigamente as más notícias nos alcançavam devagar e sorrateiramente, por longas espirais telefônicas. Davam tempo para se respirar. Hoje nos emboscam sem aviso, impiedosas, do nada, no toque de um dedo. Choque. O Dr. Matheus Marim faleceu. Como assim? Como pode Matheus Marim falecer? E a Homeopatia… como fica a Homeopatia sem ele? Revolta. Ecos de sua voz… sentimento de orfandade, de pesar, de perda… parecia não se encaixar de nenhuma maneira em seu perfil o ato de morrer. Matheus Marim, com seu jaleco branco, era figura presente em todos os congressos e eventos, personificava a própria Homeopatia. Um congresso sem ele não era um congresso completo. Mais do que exercer a profissão e de ser um grande mestre, tinha o dom de aglutinar pes-soas e talentos ao seu redor, dispostas a alcançar metas. (AU)

A research instrument was prepared containing general identification, training, working time in the PHC and clinical practice time; followed by 25 affirmative sentences. The Likert Scale was used to assess the agreement for the sentences presented. Data was collected in April 2018. 130 physicians participated in the study. Low interlocution was pointed out between PHC and SC professionals; weaknesses in the work process of family health teams, regarding to clinic management and health responsibility, pointing out that administrative issues related to the patient's internal and external flows in the health care services are more defined in the work process of the Units. Weaknesses were observed in the integration between PHC and SC, with challenges to be faced, for better integration, dialogue and quality of care for hypertensive patients. It is proposed that further studies be carried out in the territory, considering other professional categories, as well in Specialized Health Care Services.
