CONTINUITA' OSPEDALE TERRITORIO

2015

L’Italia ha una percentuale di popolazione ultrasessantacinquenne che supera il 20%, e che dovrebbe salire a oltre il 35% nel 2050. Circa 2 milioni di persone anziane non sono autonome. La prevalenza di disabilità è più alta nelle regioni meridionali del paese. L'età avanzata è un fattore di rischio indipendente per le fratture da fragilità che a lungo termine comportano un maggiore e considerevole rischio di disabilità. L’impatto delle fratture di femore è particolarmente grave negli anziani fragili. I casi più gravi di disabilità (più concentrati negli ultraottantenni) sono aumentati drammaticamente nelle ultime decade. Di conseguenza, il bisogno dei servizi di cure continuative territori…

LONGEVITY AND THE SECRETS OF CENTENARIANS

2017

Aging of the world populations represents one of the most remarkable success stories of medicine and of humankind. Hence, the search for ways to prolong health expectancy is a primary goal in medicine. Human life expectancy increased extraordinarily during the last century worldwide. Life expectancy at birth has almost doubled in most developed countries over the last century, with the oldest group being the most rapidly growing segment of the population. The number of centenarians in Italy is over 16.000 and the number is over tripled in few years (they were 5.000 in 2001). Among older population, centenarians may be considered the best example of successful aging. The capacity to avoid, d…

Profiling the risk of hepatocellular carcinoma after long-term HCV eradication in patients with liver cirrhosis in the PITER cohort

2023

Background and aims: Severe liver disease markers assessed before HCV eradication are acknowledged to usually improve after the SVR. We prospectively evaluated, in the PITER cohort, the long-term HCC risk profile based on predictors monitored after HCV eradication by direct-acting antivirals in patients with cirrhosis. Methods: HCC occurrence was evaluated by Kaplan-Meier analysis. Cox regression analysis identified the post-treatment variables associated with de-novo HCC; their predictive power was presented in a nomogram. Results: After the end of therapy (median follow-up:28.47 months), among 2064 SVR patients, 119 (5.8%) developed de-novo HCC. The HCC incidence was 1.90%, 4.21%, 6.47% a…

Volatility co-movements: a time scale decomposition analysis

2013

In this paper we investigate short-run co-movements before and after the Lehman Brothers’ collapse among the volatility series of US and a number of European countries. The series under investigation (implied and realized volatility) exhibit long-memory and, in order to avoid missspecification errors related to the parameterization of a long memory multivariate model, we rely on wavelet analysis. More specifically, we retrieve the time series of wavelet coefficients for each volatility series for high frequency scales, using the Maximal Overlapping Discrete Wavelet transform and we apply Maximum Likelihood for a factor decomposition of the short-run covariance matrix. The empirical evidence…

Wavelet Analysis Of Variance Risk Premium Spillovers

2013

In this paper we construct a variance risk premium spillover index among France, Germany, UK, Switzerland and the US. The variance risk premium is measured by the difference between the difference between the (square) of implied volatility and expected realized variance of the stock market for next month. We also construct a spillover index for the constituents of the variance risk premium. The series under investigation exhibit long memory properties. The construction of a total spillover indicator suggested by Diebold-Yilmaz (2009) would then rely on modeling a fractionally integrated Vector Autoregressive Model, which might be subject to errors in specifying the correct lag length and th…
