CT perfusion in acute ischaemic stroke within 24 hours of onset
No full textThis work, presented for examination, addresses how advanced imaging in acute stroke may be used across time windows, to identify the population who will benefit the most from reperfusion therapy at a time when resources are limited.
The time windows for reperfusion therapy have been extended (from 4.5 and 6 hours) to 9 and 24 hours for thrombolysis and endovascular therapy respectively. This extension depends on advanced imaging of penumbra and collateral circulation. However, uncertainties exist surrounding the proportion of patients with prolonged penumbral survival tissue, failure to recruit leptomeningeal collaterals and validation of current thresholds for prediction of tissue fate in late time windows.
We conducted a prospective, single-centre, observational study. Our primary objective was to identify the proportion of patients with salvageable brain tissue, at different time windows up to 24 hours after onset of acute ischaemic stroke. We also assessed collateral circulation (using both perfusion and angiographic imaging), the biological factors which may predict its demise and the time thresholds for ischaemia. We analysed imaging using three commonly used commercial software which process scans using Artificial Intelligence and found systematic differences which may influence treatment decisions.
Improved understanding of the mechanisms underpinning collateral flow, particularly the relevance of hyperglycaemia, is important in identifying a group of patients in whom very early intervention may sustain viable tissue for longer, opening the door for therapeutic interventions such as delayed revascularisation in a wider clinical group
Type I cardiorenal syndrome in patients with acutely decompensated heart failure: the importance of new renal biomarkers.
No full textOBJECTIVE: Type 1 cardiorenal syndrome (CRS) is an acute renal failure in patients with acute decompensated heart failure with an incidence of 24% to 45%. The aim of our study was to investigate the significance of new renal biomarkers to predict type 1 CRS
Subjective Well-Being among the Elderly in the Southern Cone: Health, Income and Family
No full textThe happiness literature provides evidence on various factors, other than money, that do seem to contribute
to individual happiness. As one explores the produced “happiness economics” literature, it is direct to
understand the difficulty to find proper information on developing countries reality. In our analysis we
investigate the relationship between income, family composition, health and religion over subjective wellbeing
in the Southern Cone (Argentina, Chile and Uruguay). Specifically, we analyze data from the
SABE survey a study conducted among people who are 60 years old or over, in various Latin
American countries. Main obtained results show a positive correlation between higher levels of income and
health, being married and the frequent religion practice and higher levels of subjective well-being. On the
contrary, malnutrition has a negative impact on happiness indicators. In order to add robustness to our
results and to deal with endogeneity issues, this paper uses different indicators of well-being,
alternative estimation models such as a semiparametric one and a propensity score approach for the
treatment of marriage. Latin America –and in particular the southern cone- has experienced an
increasing aging population since mid ’50. Thus, for policy makers, it is extremely useful to
disentangle the possible causes of subjective well-being among the elderly. This research and its
findings suggest guidelines to explore
