Median Arcuate Ligament Syndrome (Dunbar Syndrome): The Importance of the Pre-O...

The median arcuate ligament syndrome, also known as Dunbar syndrome, is caused by stenosis of the celiac trunk due to compression by diaphragmatic fibres. The incidence of this condition remains unclear and its clinical presentation is multifarious. Diagnosis is established by angio-computed tomography to determine the extent of stenosis and the existence or not of collateral circulation. Surgical intervention ...

PrivateCTGAN: adapting GAN for privacy-aware tabular data sharing

This research addresses the challenge of generating synthetic data that resembles real-world data while preserving privacy. With privacy laws protecting sensitive information such as healthcare data, accessing sufficient training data becomes difficult, resulting in an increased difficulty in training Machine Learning models and in overall worst models. Recently, there has been an increased interest in the usag...

Micro-MetaStream: Algorithm selection for time-changing data

Made available in DSpace on 2021-06-25T10:55:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-07-01; Data stream mining needs to deal with scenarios where data distribution can change over time. As a result, different learning algorithms can be more suitable in different time periods. This paper proposes micro-MetaStream, a meta-learning based method to recommend the most suitable learning algorithm fo...

PYLEPHLEBITIS INCIDENTALLY FOUND ON A PATIENT WITH GASTRIC CANCER

Pylephlebitis is a suppurative infection of the portal vein. This rare condition is most often related to intra-abdominal infections like appendicitis or acute diverticulitis. We present an incidentally found case of pylephlebitis in a patient who presented to the emergency department with unspecific symptoms and a recent diagnosis of gastric cancer. ; A pileflebite é uma infecção supurativa da veia porta....

A comparison of physical fitness by competitive levels in youth basketball players

Some basketball teams use train two teams at the same time. Even more, some younger players train and compete in a higher competitive level. The aim of this study was to compare the physical fitness (PF) between under sixteen (U16) and under eighteen (U18) basketball players. Body mass and height were assessed with a bioimpedance balance and a stadiometer. The strength levels were assessed for upper limbs by th...
