OBJECTIVE Compared with standard medical therapy (SMT), noninvasive ventilation (NIV) does not reduce the need for reintubation in unselected patients who develop respiratory failure after extubation. The goal of this study was to assess whether early application of NIV, immediately after extubation, is effective in preventing postextubation respiratory(More)
BACKGROUND AND PURPOSE The role of mild hyperhomocysteinemia as a risk factor for cerebral ischemia may depend on stroke subtype. To test this hypothesis, we undertook a prospective case-control study of a group of patients with spontaneous cervical artery dissection (sCAD), a group of patients with atherothrombotic stroke (non-CAD), and a group of control(More)
Several studies have been conducted to understand the genetic correlates of Alzheimer disease (AD)-related behavioral and psychological symptoms in dementia (BPSD). However, given that BPSD rarely occur in isolation, it has been suggested that targeting BPSD individually is too narrow of an approach if one wants to accurately define all the associated risk(More)
The expression of many cellular genes is modulated by DNA methylation and histone acetylation. These processes can influence malignant cell transformation and are also responsible for the silencing of DNA constructs introduced into mammalian cells for therapeutic or research purposes. As a better understanding of these biological processes may contribute to(More)
A statistical analysis was performed on a series of 170 consecutive cases of operable (M0) breast cancer in males. All the patients underwent surgery. The end-points considered were: (i) overall mortality, (ii) all neoplastic events and deaths without evidence of breast disease (first event). Five- and ten-year overall mortalities were 26.9 and 54.3%,(More)
BACKGROUND Despite best-possible medical management, many patients with end-stage cancer experience breathlessness, especially towards the end of their lives. We assessed the acceptability and effectiveness of non-invasive mechanical ventilation (NIV) versus oxygen therapy in decreasing dyspnoea and the amount of opiates needed. METHODS In this randomised(More)
BACKGROUND The gene encoding brain-derived neurotrophic factor (BDNF) has been suggested as a candidate for major depression, and for depression susceptibility in different neurological and psychiatric diseases. No study has investigated the role of BDNF genetic variation and depressive symptoms in Alzheimer's disease (AD). OBJECTIVE The aim of this study(More)
Frontotemporal Lobar Degeneration (FTLD) has always been considered a rare disorder, but only a few epidemiologic studies are available. The aim of the present work was to ascertain all FTLD patients in a Northern Italy area from January 2001 to December 2008, and to estimate the disease prevalence. On the census day, 213 FTD patients were still alive,(More)
OBJECTIVE In CSF, extended (55 kDa) and truncated (33 kDa) tau forms have been previously recognized, and the tau 33 kDa/55 kDa ratio has been found significantly reduced in progressive supranuclear palsy (PSP) vs in other neurodegenerative disorders. The aim of this study was to evaluate the diagnostic value of the CSF tau form ratio as a biomarker of PSP(More)
This paper deals with the physical and mathematical modelling description of drug release from matrix systems. In the introduction, matrix systems are considered in the wide frame of the controlled release systems and the concept of mathematical model is briefly discussed. Then, matrix structure and topology are matched, analysing the characteristics of the(More)
