The Rhythm of Time in Everyday Aesthetics

2020

Anglo-American research on aesthetics as well as that being carried out in continental Europe are increasingly interested in the topics pertaining to everyday life. However, the label “Everyday Aesthetics” apparently conveys a surprising oxymoron. After exploring the relation between Everyday and Philosophy, I shall analyse the principal theories on Everyday Aesthetics. Then, by means of anthropological interpretative tools, such as those offered by Henri Lefebvre, I will bring to the fore the concept of rhythm, as what can shed light on the fundamental value of daily life and its cyclical alternation of ordinary and extraordinary moments. According to Lefebvre, there’s no rhythm without re…

Understanding the Role of Sensorimotor Beta Oscillations

2021

Beta oscillations have been predominantly observed in sensorimotor cortices and basal\ud ganglia structures and they are thought to be involved in somatosensory processing\ud and motor control. Although beta activity is a distinct feature of healthy and pathological\ud sensorimotor processing, the role of this rhythm is still under debate. Here we review\ud recent findings about the role of beta oscillations during experimental manipulations (i.e.,\ud drugs and brain stimulation) and their alteration in aging and pathology. We show how\ud beta changes when learning new motor skills and its potential to integrate sensory input\ud with prior contextual knowledge. We conclude by discussing a n…

A Rule-Based Method to Model Myocardial Fiber Orientation for Simulating Ventricular Outflow Tract Arrhythmias

2017

Comunicació presentada a: FIMH 2017 9th International Conference, celebrada a Toronto, Canadà, de l'11 al 13 de juny de 2017. Myocardial fiber orientation determines the propagation of electrical waves in the heart and the contraction of cardiac tissue. One common approach for assigning fiber orientation to cardiac anatomi- cal models are Rule-Based Methods (RBM). However, RBM have been developed to assimilate data mostly from the Left Ventricle. In conse- quence, fiber information from RBM does not match with histological data in other areas of the heart, having a negative impact in cardiac simulations beyond the LV. In this work, we present a RBM where fiber orientation is separately mode…

Intra-cardiac Signatures of Atrial Arrhythmias Identified by Machine Learning and Traditional Features

2021

Intracardiac devices separate atrial arrhythmias (AA) from sinus rhythm (SR) using electrogram (EGM) features such as rate, that are imperfect. We hypothesized that machine learning could improve this classification.

In-Hospital and One-Year Outcomes of Patients after Early and Late Resuscitated Cardiac Arrest Complicating Acute Myocardial Infarction—Data fr…

2022

The prognostic role of early (less than 48 h) resuscitated cardiac arrest (ErCA) complicating acute myocardial infarction (AMI) is still controversial. The present study aimed to analyse the short-term and one-year outcomes of patients after ErCA and late resuscitated cardiac arrest (LrCA) compared to patients without cardiac arrest (CA) complicating AMI. Data from the prospective nationwide Polish Registry of Acute Coronary Syndromes (PL-ACS) were used to assess patients with resuscitated cardiac arrest (rCA) after AMI. Baseline clinical characteristics and the predictors of all-cause death were assessed. The all-cause mortality rate, complications, performed procedures, and re-hospitalisa…

2020

Background: several studies report an increased risk for asthmatic subjects to develop arterial hypertension and the relationship between these two diseases, frequently co-existing, still has some unclear aspects. Methods: The BADA (blood pressure levels, clinical features and markers of subclinical cardiovascular damage of asthma patients) study is aimed to evaluate the prevalence of the cardiovascular comorbidities of asthma and their impact on the clinical outcome. The main exclusion criteria were the presence of other respiratory diseases, current smoking, any contraindication to ambulatory blood pressure monitoring (ABPM). Results: The overall percentage of asthmatics having also hyper…

An Automata-Based Cardiac Electrophysiology Simulator to Assess Arrhythmia Inducibility

2022

Personalized cardiac electrophysiology simulations have demonstrated great potential to study cardiac arrhythmias and help in therapy planning of radio-frequency ablation. Its application to analyze vulnerability to ventricular tachycardia and sudden cardiac death in infarcted patients has been recently explored. However, the detailed multi-scale biophysical simulations used in these studies are very demanding in terms of memory and computational resources, which prevents their clinical translation. In this work, we present a fast phenomenological system based on cellular automata (CA) to simulate personalized cardiac electrophysiology. The system is trained on biophysical simulations to re…

Hair Cortisol Concentration as a Biomarker of Sleep Quality and Related Disorders

2021

Cortisol is the end product of the hypothalamic-pituitary-adrenal (HPA) axis, and its production is increased mainly in stressful situations or in chronic disorders accompanied by stress enhancement. Altered cortisol concentrations have been reported in a number of neuropsychiatric diseases and sleep disorders. Cortisol concentrations have been measured using several methods, and in several matrixes, such as blood, saliva, and urine. However, lately, hair cortisol, for several reasons, has emerged as a promising biomarker of long-term retrospective HPA activation. Several experimental approaches for cortisol measurement with the corresponding concentration reference ranges and a summary of …

Sleep and Chronobiology as a Key to Understand Cluster Headache

2023

The cluster headache is a primary headache characterized by attacks of unilateral pain associated with ipsilateral cranial autonomic features. These attacks recur in clusters during the years alternating with periods of complete remission, and their onset is often during the night. This annual and nocturnal periodicity hides a strong and mysterious link among CH, sleep, chronobiology and circadian rhythm. Behind this relationship, there may be the influence of genetic components or of anatomical structures such as the hypothalamus, which are both involved in regulating the biological clock and contributing even to the periodicity of cluster headaches. The bidirectional relationship manifest…
