Childhood cancer incidence and survival in Spain
2010
Abstract Background: This article affords an overview of the patterns and time trends of childhood cancer incidence (1983–2002) and survival (1991–2002) in Spain. Patients and methods: A population-based study was conducted, including 5936 cases for incidence and 3257 for survival analyses. Differences in incidence were tested with the standardised incidence ratio. Trends were analysed for all tumours, and for all malignant, haematological, central nervous system (CNS) (all and only malignant) and other solid tumours. Incidence trends were analysed using Poisson and Bayesian joinpoint models. Observed, relative and age-adjusted survival rates were calculated, and trends were tested using th…
Strong influence of lowermost stratospheric ozone on lower tropospheric background ozone changes over Europe
2007
[1] Using ozone measurements from two sounding sites and two high-altitude stations in Central Europe, we show evidence for a dominant influence of changes in lowermost stratospheric ozone on the variability and overall upward trend of background ozone in the lower troposphere (3000–3500 m asl) during the 1992–2004 period. Numerical simulations with a stratospheric chemistry transport model suggest that changes in lower stratospheric ozone were driven by dynamics rather than by changes in stratospheric chlorine loading. In addition, Lagrangian model simulations indicate that changes in downward transport of ozone from the stratosphere into the troposphere were dominated by changes in lowerm…
Hematological Malignancies in the Elderly: The Epidemiological Perspective
2014
In the more developed countries the total number of new cases with a hematological tumour was 415,433 for all ages, whilst 188,654 occurred in people aged 70 or more years, representing the 45 % of total cases, equally divided into two sexes. The most these malignancies is closely linked to age and incidence rates increased exponentially after 50 years of age. Aetiology of hematological tumours is largely unknown. However the basic causal mechanism could be a decline in adaptive immunity, strongly related with individual age. In addition to such immunodeficiency, some specific risk factors have been found: viral infections, overweight and obesity (particularly for non-Hodgkin’s lymphomas - …
The impact of mandatory vaccination law in Italy on mmr coverage rates in two of the largest italian regions (Emilia-romagna and sicily): An effectiv…
2020
Background: Vaccine hesitancy has increased worldwide, leading to reduction in vaccination coverage rates. In particular, reduction in the coverage for the trivalent Measles-Mumps-Rubella vaccine has led to an increase of measles cases. The aim of this study is to analyze the coverage rates for the MMR vaccine in the Emilia-Romagna Region (RER) and Sicily Region (SR) between 2009 and 2018, and to correlate any significant change to index events which could have modified the trend of vaccination rates. Methods: Official aggregate data on vaccination coverage at 24 months provided by the RER and the SR were analyzed through trend analysis and related to important index events. Results: The tw…
Trends in gastrointestinal bleeding in the Region of Valencia (2000-2005). Relationship to sales of nonsteroidal anti-inflammatory drugs and acid sup…
2011
Objective: To describe 2000-2005 time trends of prescription for NSAIDs, proton pump inhibitors (PPIs) and hospital admissions for gastrointestinal (GI) bleeding. Methods: Time series analysis of gastrointestinal (GI) bleeding admission and drugs’ Defined Daily Dose per 1000 people per day (DDD/1000/day) in the Region of Valencia, Spain, from January 2000 to December 2005. Results: Dispensation of NSAIDs went from 42.7 DDD/1000 people/day in 2000 to 58.3 DDD/1000 people/day in 2005. During the same period, dispensation of PPIs went from 26.3 DDD/1000 people/day to 68.5 DDD/1000 people/day (both are statistically significant). The rate of hospitalisations for gastrointestinal bleeding during…
Libraries and Intellectual Debate in the Late Republic: the Case of the Aristotelian Corpus
2013
The present chapter explores the catalyzing function of libraries in the intellectual debate of the late Roman Republic, by focusing on the significant case of the Aristotelian esoteric corpus. A careful analysis of the literary and historical evidence concerning the use of Peripatetic texts allows to detect the presence of at least two important libraries containing Aristotle's 'pragmatiai' in Roman Italy: Lucullus' collection in Tusculum and Sulla's one in Cumae. Several Greek and Latin sources bear witness to the vicissitudes of such libraries, and the present paper reassesses their accounts in order to point out the close connection between intellectual patterns and material culture - i…
Early perception of phrasal prosody and its role in syntactic and lexical acquisition
2018
Chapter: 2, pp. 17-35; International audience; This chapter will review empirical findings on the perception of phrasal prosody in very young infants, and how it develops in first language acquisition. The ability to process phrasal prosody impacts learning of important aspects of language, specifically word segmentation and syntactic parsing. We will see that infants are able to perceive crucial aspects of phrasal prosody before the end of their first year of life, and that a few months later they are able to exploit the prosodic structure of an utterance to constrain its syntactic analysis, and therefore, to infer the meaning of unknown words.
Cyclic influences on the heavy metal chronology in a Central Mediterranean area (Palermo Gulf, Italy)
2010
PurposeThe evaluation of long-term heavy metal concentrations in the Gulf of Palermo (Italy) has been carried out in order to investigate how changes of pollution levels in the last 50 years can be reflected in marine sediments. Measurements of Cr, Cu, Hg, Pb, and Zn concentrations were performed on dated fractions of a sediment core. Time series analysis has allowed to obtain information on the chronology of the heavy metal pollution of the area and to identify seasonal components and trends.Materials and methodsHeavy metal concentrations in the <63 μm fraction of core sections were obtained by Atomic Absorption Spectrophotometry, after wet sieving, drying, and digestion procedures. Dating…
Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight
2021
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia…
International student mobility in Southern-Latin Europe: beyond the EU logics, towards a new space
2018
This paper discusses international student mobility (ISM) in Southern-Latin Europe, specifically Italy, Portugal, and Spain, analysing the inflow of international students as reflected in the UNESCO, OECD and European Commission databases. Only recently Italy, Portugal and Spain, as latecomers, have become more actively involved in ISM dynamics. This trend has been a response to EU pressures to internationalization, instrumented through the consolidation of the Bologna process and the need to build a common space of higher education. The analysis shows that at the intra-European level Italy, Portugal and Spain share similar ISM patterns; however, in the global context other logics shape ISM…
