Single-slice Alzheimer's disease classification and disease regional analysis with Supervised Switching Autoencoders.

Background: Alzheimer's disease (AD) is a difficult to diagnose pathology of the brain that progressively impairs cognitive functions. Computer-assisted diagnosis of AD based on image analysis is an emerging tool to support AD diagnosis. In this article, we explore the application of Supervised Switching Autoencoders (SSAs) to perform AD classification using only one structural Magnetic Resonance Imaging (sMRI) slice.

The long-term effects of the Kangaroo Mother Care intervention on cognitive functioning: Results from a longitudinal study.

This study aimed to evaluate the long-term effects of the Kangaroo Mother Care (KMC) intervention on the intellectual and attentional functioning of young adults born with low birth weight. Three hundred infants were randomly assigned at birth in one of two interventions, KMC or traditional care (TC), and completed cognitive tests at adulthood (19-21 years after recruitment). The main results show that participants with a neurological vulnerability at 6 months had higher IQ and sustained attention scores at adulthood if they had received KMC than if they had received TC.

[Thrombotic and haemorrhagic complications in patients with cerebral aneurysms treated by endovascular approach and their association with the use of antiplatelet agents: Descriptive evaluation].

Objective: The protocol for optimal antiplatelet therapy to prevent thrombotic complications following brain aneurysm embolisation is not clear. Our objective is to describe the characteristics of patients presenting with thrombotic or haemorrhagic complications secondary to endovascular treatment.

Methods: A cross sectional descriptive study was performed, which included all patients that required endovascular treatment for brain aneurysm at San Ignacio University Hospital from November 2007 to January 2016.

[Correlation between cholangiopancreatography by magnetic resonance and the endoscopic retrograde colangiopancreatography in hospitalized by biliary lithiasis in the University Hospital San Ignacio (Bogota-Colombia) between 2005 to 2011].

Objective: Determine the grade of agreement between the colangiopancreatography by magnetic resonance (CPRM) and the endoscopic retrograde colangio pancreatography (ERCP) in hospitalized patients by biliary lithiasis in a period of time in a reference hospital.

Material And Methods: Type of study, retrospective evaluation of diagnostic tool, the size of the sample was calculated from the pilot simple and was 320 patients. We recolected 354 patients that urderwent both studies (CPRM and ERCP), to evaluate the correlation between both procedures we used Kappa variation.
