TEVAR for primary aortic mural thrombus: when and how?

INTRODUCTION: Primary aortic mural thrombus (PAMT) is a rare cause of peripheral embolization that has been associated with hypercoagulable states. Anticoagulation is usually the first-line strategy, but has been associated with a significant risk of recurrent embolization. CASE-REPORT: A 51-year-old male patient with a history of right lung carcinoma underwent a follow-up computed tomography angiography (CTA) ...

Preventing Proximal Femur Pathologic Fractures Improves Outcomes in Patients wi...

INTRODUCTION: Metastatic bone disease decreases a patient’s function and increases morbidity being frequently found in patients with solid malignant tumors and multiple myeloma (MM). The effective treatment of these patients demands a multidisciplinary team approach to prevent catastrophic events such as pathologic fractures, especially in the proximal femur. This study aimed to evaluate oncologic outcomes, sur...

Sustainable Tourism Marketing Through Destination Image: An AHP Approach for UN...

Popayán (Colombia) was the first city to be designated a UNESCO Creative City of Gastronomy in 2005, positioning itself as a symbolic ‘myth of origin’ within the network. In the context of growing demands for local strategies aligned with the Sustainable Development Goals (SDGs), it is pertinent to understand how founding cities manage and project their image through sustainable tourism marketing. Almost two de...

Bibliometric Analysis of Key Variables in Tourism: Destination, Competitiveness...

In the scientific literature on tourism, a set of variables is frequently utilized. The objective of this study is to analyze the scenario of scientific publications on these variables between 2000 and 2023. This analysis employs a bibliometric approach, utilizing data collected from the Scopus database. The bibliometric method was employed, with a focus on five variables (tourism destination, competitiveness, ...

Two-Staged Treatment of Symptomatic Complex Type 2 Thoracoabdominal Aneurysm wi...

Improving Sarcopenia Diagnosis and Management Through Training in a Cohort of P...

Introduction: Although sarcopenia has been formally recognized in the World Health Organization International Classification of Diseases, it is still underdiagnosed and undertreated in clinical practice. This study aimed to assess the current knowledge and management of sarcopenia in a cohort of Portuguese physicians and the effectiveness of a training session on sarcopenia diagnosis and treatment. Methods: Thi...

ESS design and management considering solar PV to fed off-grid EV charger

The increase of electric vehicles creates several challenges to the electric grid, mainly in those with weak power or off-grid. DC microgrids are becoming more and more important in the context of renewable energy sources, where solar PV systems are dominant. In this paper is proposed the design of a DC system to charge electric vehicles using PV generation and a battery storage system. A single DC-DC converter...

A convolutional variant of the Niederreiter cryptosystem with GRS codes

In this work we study a variant of the Niederreiter cryptosystem. Instead of hiding the parity-check matrix of the secret code with constant matrices, we propose to use polynomial matrices. The public key is then the parity-check matrix of a convolutional code. The plaintext is a sequence of vectors of low weight and the ciphertext is the syndrome of this sequence. We propose the use of a Generalized Reed-Solom...

Como melhorar a saúde das crianças e dos adolescentes? Algumas preocupações, co...

Introdução: Os cuidados de saúde primários representam o primeiro nível de intervenção dos serviços de saúde. Em idade pediátrica, uma vigilância rigorosa é de extrema importância, pois influencia o crescimento e o bem-estar biopsicossocial, com repercussões na idade adulta. Objetivo: Descrever as principais preocupações sentidas nas consultas de vigilância de saúde infantil e juvenil durante o estágio de cuida...
