RESUMO

A manually classified dataset of images obtained by four static cameras located around a construction site is presented. Eight object classes, typically found in a construction environment, were considered. The dataset consists of 1046 images selected from video footage by a frame extraction algorithm and txt files containing the objects' class and coordinates information. These data can be used to develop computer vision techniques in the engineering and construction fields.

RESUMO

Cardiac amyloidosis (CA) is a form of cardiomyopathy characterized by the extracellular deposit of protein fibers in the myocardium, leading to the development of heart failure, arrhythmias, and electrical conduction system alterations. It is known that most cardiomyopathies have a close relationship with heart rhythm abnormalities, however, CA is specially related to different kinds of arrhythmias even in pre-diagnosis stages. Arrhythmias like atrial fibrillation are present in up to 70% of patients with CA associated with a high risk of cardioembolic complications independent of the risk stratification. Ventricular arrhythmias are frequent, but the use of implantable cardioverter defibrillator has not been demonstrated to improve survival. The Atrial-Ventricular node disease is also common, and is frequently associated with the implantation of a pacemaker, even in asymptomatic patients. In this review, we clarify the recommendations of the most current guidelines, summarize historical and contemporaneous data and describe evidence-based strategies for the management of arrhythmias and their complications in CA.

RESUMO

Aquatic organisms that inhabit coastal areas are often exposed to several contaminants. It is known that the bioaccumulation of contaminants can be amplified according to the species feeding habits and contaminant properties. As a consequence, species can experience different effects to contaminant exposure even if they inhabit the same area. The present study aimed to investigate the activities of carbonic anhydrase (CA), Ca2+-ATPase, and Mg2+-ATPase in different tissues (soft tissue, mantle, and gill) of three mollusk species (Lottia subrugosa, Stramonita brasiliensis, and Crassostrea brasiliana) with different feeding habits (herbivore, carnivore, and filter-feeder, respectively) which were sampled within a known contamination gradient at Santos Estuarine System (Southeastern Brazil). From the three enzymes tested, only CA was affected by the presence of contaminants within the contamination gradient evaluated. In general, the CA activity from the three species were lower in contaminated sites when compared to the reference site. The contrasting CA activity response observed in S. brasiliensis compared to L. subrugosa and C. brasiliana could be related to the tissue-specificity of this enzyme activity and species feeding habits (filter-feeders can accumulate more contaminants than herbivores and even carnivores). Results indicated that C. brasiliana mantle is the most suitable tissue for the use of CA analysis as a biomarker.

RESUMO

Resumen Presentamos un caso de síndrome de marcapasos asociado a la ausencia de sincronía aurículo-ventricular, debido a la colocación invertida e inadvertida de los electrodos, en una paciente portadora de bloqueo aurículo-ventricular completo; para su diagnóstico, es fundamental un cuidadoso análisis del electrocardiograma, las imágenes con rayos X y los electrogramas intracavitarios.

Abstract Pacemaker syndrome: what is the mechanism? We present the case of pacemaker syndrome related to the absence of atrioventricular synchrony, due to inverted and inadvertent placement of the electrodes, in a patient with complete atrioventricular block. A careful analysis of the electrocardiogram, X-ray images and intracavitary electrograms are essential for its diagnosis.

RESUMO

Resumen: Objetivo general: Determinar la incidencia de la trombosis venosa (TV) e infección asociada con el catéter central de inserción periférica (PICC). Material y métodos: Se realizó un estudio retrospectivo, replicativo y descriptivo, cuya duración fue de 38 meses. Los catéteres centrales de inserción periférica se colocaron por el Servicio de Radiología Intervencionista con la misma técnica en las extremidades superiores. Se guardó una imagen del procedimiento con el nombre y diámetro de la vena usada. En el estudio se incluyó a partir del primer catéter PICC colocado en marzo de 2015 hasta el último en abril de 2018. Se registraron las trombosis venosas demostradas por ultrasonido Doppler, la duración del catéter y las bacteriemias relacionadas con el PICC (BRC-PICC). Resultados: Se colocaron 448 PICC y, de éstos, se excluyeron 78. Los 370 catéteres restantes sumaron 3,363 días-catéter. El 99.45% de los procedimientos resultaron exitosos. La incidencia de trombosis encontrada fue de 0.016% (n = 6) y la de infección de 0.03% (n = 12). El vaso más frecuentemente utilizado fue la vena basílica derecha. Conclusiones: La incidencia tanto de trombosis como de infección se mantiene por debajo de las reportadas en la literatura. Las venas mayores a 3.8 mm de diámetro tienen una probabilidad muy baja de presentar trombosis venosa.

Abstract: Objective: To determine the incidence of venous thrombosis (VT) and infection associated with PICC lines. Material and methods: A retrospective, replicative and descriptive study was conducted over 38 months. The PICC line was inserted in the upper extremities by the Interventional Radiology Service with the same technique. An image of the procedure with the name and diameter of the selected vein was saved. Venous thrombosis, demonstrated by Doppler ultrasound, the duration of the catheter and bacteremia related to the PICC line (BRC-PICC) were recorded. Results: 448 PICCs were placed and 78 were excluded. The remaining 370 catheters added 3,363 catheter days. 99.45% of the procedures were technically successful. The incidence of thrombosis was 0.016% (n = 6) and that of infection 0.03% (n = 12). The most frequently selected vessel was the right basilic vein. Conclusions: The incidence of thrombosis and infection were below the reported in the literature. Veins greater than 3.8 mm have a very low probability of having TV.

RESUMO

ABSTRACT Objective: This study analyzes dental surgeons' knowledge and clinical practice regarding sickle cell disease (SCD) at Family Health Units in Recife, northeastern Brazil. Methods: This cross-sectional study was conducted in a representative sample of dentists using a standardized questionnaire. Data were analyzed by descriptive statistics. Results: Out of 132 eligible dental surgeons, 124 (93.9%) were interviewed. Most of them were women (81.5%), aged between 28 and 39 years (53.2%), with more than 15 years of experience (52.4%). A percentage of 89.5% knew the definition and oral manifestations (53.2%) of the disease, but only 17.7% knew the dental care protocol. It was verified that 13.6% of the dentists who knew how to conduct the treatment had acquired this knowledge during their undergraduate studies. Conclusion: Regarding clinical practice, 71.8% said they would treat patients with SCD; however, 67.7% had never done that. Most dentists felt confident of performing dental procedures (82%) and their major difficulty was their lack of knowledge about the disease (57.1%). The findings suggest the need for the implementation of public policies for improving the qualification of dental surgeons who work in primary healthcare, thus minimizing risks during the dental care of SCD patients.

RESUMO Objetivo: Este estudo analisa o conhecimento e a atuação sobre doença falciforme de cirurgiões-dentistas de Unidades de Saúde da Família no Recife/Pernambuco. Métodos: O estudo transversal foi conduzido em amostra representativa de profissionais utilizando-se questionário padronizado. Os dados foram analisados por estatística descritiva. Resultados: Dos 132 cirurgiões-dentistas elegíveis, 124 (93,9%) foram entrevistados. A maioria era composta por mulheres (81,5%) com idade entre 28 e 39 anos (53,2%), com mais de 15 anos de formado (52,4%). Um percentual de 89,5% sabia a definição e as manifestações bucais (53,2%) da doença, apenas 17,7% conhecia o protocolo de atendimento odontológico. Verificou-se que 13,6% dos profissionais que conheciam o manejo do atendimento obtiveram esse conhecimento durante o curso de graduação. Quanto à atuação, 71,8% dos profissionais atenderia paciente com doença falciforme, no entanto, 67,7% dos profissionais nunca fizeram este acolhimento. A maioria se sente seguro para realizar procedimentos odontológicos (82%) e a principal dificuldade para o atendimento foi à falta de conhecimento sobre o assunto (57,1%). Conclusão: Este resultado sugere a necessidade da implementação de políticas públicas que objetivem reforçar a capacitação dos cirurgiões-dentistas que atuam na atenção básica, a fim de minimizar os riscos durante o atendimento odontológico desses pacientes.
