Lista Rossa IUCN della Flora Italiana. 1. Policy Species e altre specie minacciate
2013
As part of the Mediterranean global biodiversity hotspot, the Italian flora is particularly rich of species, many of them endemic to restricted territories. In some areas of Italy endemic plant species reach very high percentages, between 13% and 20% of the local flora. However, plant diversity in the Mediterranean Basin is facing several threats due to changes of the current socio-economic dynamics. Italy is not an exception and urgent conservation measures are needed to halt the loss of biodiversity and preserve the numerous threatened species. This volume is the output of a project started in 2012, funded by the Italian Ministry of Environment for the Protection of Land and Sea and carri…

The use of emergency laparoscopy for acute abdomen in the elderly: the FRAILESEL Italian Multicenter Prospective Cohort Study
2020
As the world population is aging rapidly, emergency abdominal surgery for acute abdomen in the elderly represents a global issue, both in developed and developing countries. Data regarding all the elderly patients who underwent emergency abdominal surgery from January 2017 to December 2017 at 36 Italian surgical departments were analyzed with the aim to appraise the contemporary reality regarding the use of emergency laparoscopy for acute abdomen in the elderly. 1993 patients were enrolled. 1369 (68.7%) patients were operated with an open technique; whereas, 624 (31.3%) underwent a laparoscopic operation. The postoperative morbidity rate was 32.6%, with a statically significant difference b…
Risk factors for postoperative morbidity following appendectomy in the elderly: a nationwide prospective cohort study
2019
Background: A limited number of studies investigating perioperative risk factors associated with emergency appendectomy in elderly patients have been published to date. Whether older age may be associated with poorer outcomes following appendectomy is still a matter of debate. The primary aim of this study was to determine the predictors of postoperative morbidity following appendectomy in patients aged ≥ 65 years. Methods: Data regarding all elderly patients who underwent emergency appendectomy from January 2017 to June 2018 admitted 36 Italian surgical departments were prospectively collected and analyzed. Baseline demographics and perioperative variables were evaluated. Uni- and multivar…
Effect of COVID-19 pandemic lockdowns on planned cancer surgery for 15 tumour types in 61 countries: an international, prospective, cohort study
2021
This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index 60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models wer…
Cardiovascular events and intensity of treatment in polycythemia vera.
2013
A b s t r ac t Background Current treatment recommendations for patients with polycythemia vera call for maintaining a hematocrit of less than 45%, but this therapeutic strategy has not been tested in a randomized clinical trial. Methods We randomly assigned 365 adults with JAK2-positive polycythemia vera who were being treated with phlebotomy, hydroxyurea, or both to receive either more intensive treatment (target hematocrit, <45%) (low-hematocrit group) or less intensive treatment (target hematocrit, 45 to 50%) (high-hematocrit group). The primary composite end point was the time until death from cardiovascular causes or major thrombotic events. The secondary end points were cardiovascula…
B-K-parameter from N-f=2 twisted mass lattice QCD
2011
We present an unquenched N-f = 2 lattice computation of the B-K parameter which controls K-0 - (K) over bar (0) oscillations. A partially quenched setup is employed with two maximally twisted dynamical (sea) light Wilson quarks, and valence quarks of both the maximally twisted and the Osterwalder-Seiler variety. Suitable combinations of these two kinds of valence quarks lead to a lattice definition of the B-K parameter which is both multiplicatively renormalizable and O(a) improved. Employing the nonperturbative RI-MOM scheme, in the continuum limit and at the physical value of the pion mass we get B-K(RGI) = 0.729 +/- 0.030, a number well in line with the existing quenched and unquenched d…
