Subfossil chironomid assemblages in deep, stratified European lakes: relationships with temperature, trophic state and oxygen
2010
Summary 1. The distributions of subfossil remains of chironomid larvae in 28 large, deep and stratified lakes in Europe were examined in surface sediments along a latitudinal transect ranging from northern Sweden to southern Italy. 2. Canonical correspondence analysis (CCA) showed that summer surface water and July air temperature, as well as total phosphorus (TP) concentrations, hypolimnetic oxygen availability and conductivity were statistically significant (P < 0.05) explanatory variables explaining between 11 and 14% of the variance in the chironomid data. 3. Owing to the spatial scale covered by our study, many environmental variables were covarying. Temperature, TP concentration and o…
Time trends of human papillomavirus types in invasive cervical cancer, from 1940 to 2007.
2013
Contribution over time of human papillomavirus (HPV) types in human cancers has been poorly documented. Such data is fundamental to measure current HPV vaccines impact in the years to come. We estimated the HPV type-specific distribution in a large international series of invasive cervical cancer (ICC) over 70 years prior to vaccination. Paraffin embedded ICC cases diagnosed between 1940 and 2007 were retrieved from eleven countries in Central-South America, Asia and Europe. Included countries reported to have low-medium cervical cancer screening uptake. Information on age at and year of diagnosis was collected from medical records. After histological confirmation, HPV DNA detection was per…
Human papillomavirus genotype distribution in cervical cancer cases in Spain. Implications for prevention
2011
Objective. Human papillomavirus (HPV) genotype distribution in invasive cervical cancer (ICC) is critical to guide the introduction and to assess the impact of HPV prophylactic vaccines. This study aims to provide specific information for Spain. Methods. 1043 histological confirmed ICC cases diagnosed from 1940 to 2007 from six Spanish regions were assembled. HPV DNA detection was performed by SPF10 broad-spectrum PCR followed by deoxyribonucleic acid enzyme immunoassay and genotyping by reverse hybridization line probe assay (LiPA(25)) (version 1). Results. Of 1043 ICC cases, 904 were HPV DNA positive (adjusted prevalence: 89.1%). The eight most common types, in decreasing order, were HPV …
Survival of male genital cancers (prostate, testis and penis) in Europe 1999-2007: Results from the EUROCARE-5 study
2015
Abstract Background We provide updated estimates of survival and survival trends of male genital tumours (prostate, testicular and penis cancers), in Europe and across European areas. Methods The complete approach was used to obtain relative survival estimates for patients diagnosed in 2000–2007, and followed up through 2008 in 29 countries. Data came from 87 cancer registries (CRs) for prostate tumours and from 86 CRs for testis and penis tumours. Relative survival time trends in 1999–2007 were estimated by the period approach. Data came from 49 CRs in 25 countries. Results We analysed 1,021,275 male genital cancer cases. Five-year relative survival was high and decreased with increasing a…
Time trends of cancer incidence in European children (1978-1997): Report from the Automated Childhood Cancer Information System project.
2006
Within the framework of the Automated Childhood Cancer Information System (ACCIS), time trend analyses for childhood cancer were performed using data from 33 population-based cancer registries in 15 European countries for the period 1978-1997. The overall incidence rate based on 77,111 cases has increased significantly (P<0.0001), with an average annual percentage change (AAPC) of 1.1%. The rising trend was observed in all five geographical regions and in the majority of the disease groups (in order of AAPC): soft tissue sarcomas (1.8%), brain tumours, tumours of the sympathetic nervous system, germ-cell tumours, carcinomas, lymphomas, renal tumours, and leukaemias (0.6%). No change was see…
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…
