Comparing outcomes after open and endovascular chronic mesenteric ischemia reva...

INTRODUCTION: Chronic mesenteric ischemia (CMI) is a rare but life-threatening disease. This study aimed to analyze the safety and effectiveness of open (OR) and endovascular (ER) revascularization and respective outcomes in a consecutive series of CMI patients. METHODS: From 2013 to 2023, all CMI patients treated with OR and ER were retrospectively identified. Demographics, comorbidities, clinical presentation...

Recanalization of chronic total ilio-caval occlusion

PD-1 and ICOS are coexpressed in T follicular helper cells but define three sta...

Humoral responses to infection or vaccination require T cell-B cell interactions. T follicular helper (TFH) cells drive germinal center (GC) responses by providing help to B cells, whereas T follicular regulatory (TFR) cells regulate them. Both mature GC-located TFH and TFR cells are widely characterized by the expression of ICOS and PD-1. However, although human TFR cells share many phenotypic characteristics ...

Intravascular Lithotripsy For Severe Peripheral Artery Calcification – A 3-Year...

Introduction: Severe arterial calcification is a challenging limitation in endovascular procedures leading to worse success rates and outcomes. Conventional balloon angioplasty may provide limited luminal gain, calling for adjunctive strategies of plaque modification, such as intravascular lithotripsy (IVL). The aim of this study is to describe our institutional experience with IVL in the treatment of periphera...

Unfractionated Heparin in Ruptured Aortic Aneurysms – Narrative Review

INTRODUCTION: Portuguese estimates point out that nearly 20% of aortic aneurysms are treated in a ruptured setting, with in-hospital mortality reaching up to 50%. Although unfractionated heparin (UFH) is routine during elective surgery, this technical point is debatable when treating ruptured aneurysms. The authors aimed to review the literature on the topic of intraoperative heparinization with UFH within the ...

Integration of Citizen’s Card Digital Authentication in Hyperledger

This study investigates the integration of the Portuguese Citizen’s Card authentication with Hyperledger Fabric blockchain technology, addressing the challenge of bridging traditional government-issued digital identities with blockchain-based systems, particularly focusing on reducing barriers to Web3 adoption for users unfamiliar with decentralized technologies. The proposed solution leverages the Autenticação...

MERGE App: A Prototype Software for Multi-User Emotion-Aware Music Management

We present a prototype software for multi-user music library management using the perceived emotional content of songs. The tool offers music playback features, song filtering by metadata, and automatic emotion prediction based on arousal and valence, with the possibility of personalizing the predictions by allowing each user to edit these values based on their own emotion assessment. This is an important featu...

This initial section aims to provide context for the current significance of technology adoption in tourism and an insight into the prevailing strategies and challenges faced by the industry. In light of this context, it becomes essential to delve into the scientific literat...

The Influence of Artificial Intelligence on Advertising

This chapter explores the profound influence of artificial intelligence (AI) on advertising, covering its historical context, current trends, and future implications. Initially, advertising relied on manual data analysis, but AI has shifted the landscape towards more targeted campaigns. AI's role began with predictive analytics for weather forecasting in the 1950s and evolved to include collaborative filtering ...
