Dietary habits and geographic variation in stomach cancer mortality in Spain
1996
Following examination of the geographical pattern of stomach cancer incidence in Spain, the possible relationship between diet and stomach cancer has been assessed using an ecological model which looks into the relationship between the consumption of different foods and the nutrient intake in each of the 50 Spanish provinces during the period 1964-65, and the mortality rate for stomach cancer in these same 50 provinces during a period 20 years later (1984-86). The geographical pattern of stomach cancer mortality has been arrived at using the standardized mortality ratios (SMRs) calculated for each province. The per capita consumption of foods was obtained from the National Institute for Sta…
Survival of European children and young adults with cancer diagnosed 1995-2002
2009
This study analyses survival in 40,392 children (age 0-14 years) and 30,187 adolescents/young adults (age 15-24 years) diagnosed with cancer between 1995 and 2002. The cases were from 83 European population-based cancer registries in 23 countries participating in EUROCARE-4. Five-year survival in countries and in regional groupings of countries was compared for all cancers combined and for major cancers. Survival for 15 rare cancers in children was also analysed. Five-year survival for all cancers combined was 81% in children and 87% in adolescents/young adults. Between-country survival differences narrowed for both children and adolescents/young adults. Relative risk of death reduced signi…
Impact of screening programme using the faecal immunochemical test on stage of colorectal cancer: Results from the IMPATTO study
2019
To evaluate the impact of faecal immunochemical test (FIT) screening on stage distribution at diagnosis, and to estimate relative incidence rates by stage in screened at first and subsequent rounds vs. unscreened. We included all incident cases occurring in 2000-2008 in 50- to 71-year-olds residing in areas with an FIT-screening programme. Multinomial logistic models were computed to estimate the relative risk ratio (RRR) of stages I and IV, compared to stage II + III, adjusting for age, sex, geographical area, and incidence year. Proportions were then used to estimate incidence rate ratios (IRR) by stage for screened subjects at the first and at subsequent rounds vs. unscreened subjects, a…
Two-level resolution of relative risk of dengue disease in a hyperendemic city of Colombia.
2018
Risk maps of dengue disease offer to the public health officers a tool to model disease risk in space and time. We analyzed the geographical distribution of relative incidence risk of dengue disease in a high incidence city from Colombia, and its evolution in time during the period January 2009—December 2015, identifying regional effects at different levels of spatial aggregations. Cases of dengue disease were geocoded and spatially allocated to census sectors, and temporally aggregated by epidemiological periods. The census sectors are nested in administrative divisions defined as communes, configuring two levels of spatial aggregation for the dengue cases. Spatio-temporal models including…
N-terminal Pro-brain Natriuretic Peptide and High-sensitivity Troponin in the Evaluation of Acute Chest Pain of Uncertain Etiology. A PITAGORAS Subst…
2013
Abstract Introduction and objectives High-sensitivity troponin assays have improved the diagnosis of acute coronary syndrome in patients presenting with chest pain and normal troponin levels as measured by conventional assays. Our aim was to investigate whether N-terminal pro-brain natriuretic peptide provides additional information to troponin determination in these patients. Methods A total of 398 patients, included in the PITAGORAS study, presenting to the emergency department with chest pain and normal troponin levels as measured by conventional assay in 2 serial samples (on arrival and 6 h to 8 h later) were studied. The samples were also analyzed in a central laboratory for high-sensi…
The Impact of World and European Football Cups on Stroke in the Population of Dijon, France: A Longitudinal Study from 1986 to 2006
2013
Background: Acute stress may trigger vascular events. We aimed to investigate whether important football competitions involving the French football team increased the occurrence of stroke. Methods: We retrospectively retrieved data of fatal and nonfatal stroke during 4 World Football Cups (1986, 1998, 2002, and 2006) and 4 European Championships (1992, 1996, 2000, and 2004), based on data from the population-based Stroke Registry of Dijon, France. One period of exposure was analyzed: the period of competition extended to 15 days before and after the competitions. The number of strokes was compared between exposed and unexposed corresponding periods of preceding and following years using Poi…
Changes in the Effect of Heat on Mortality in the Last 20 Years in Nine European Cities. Results from the PHASE Project
2015
The European project PHASE aims to evaluate patterns of change in the temperature–mortality relationship and in the number of deaths attributable to heat in nine European cities in two periods, before and after summer 2003 (1996–2002 and 2004–2010). We performed age-specific Poisson regression models separately in the two periods, controlling for seasonality, air pollution and time trends. Distributed lag non-linear models were used to estimate the Relative Risks of daily mortality for increases in mean temperature from the 75th to 99th percentile of the summer distribution for each city. In the recent period, a reduction in the mortality risk associated to heat was observed only in Athens,…
Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risk…
2015
Summary Background The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution. Methods Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2…
Perceived age as a predictor of old age mortality: a 13-year prospective study
2005
Objectives To examine whether in older people perceived age is associated with risk of total mortality independent of chronological age. Design Prospective population-based study (Evergreen project) with mortality surveillance for 13 years after the baseline. Setting Face-to-face interview among community-dwelling residents of the city of Jyvaskyla, Finland. Subjects 395 men and 770 women aged 65-84 years at baseline. Measures Perceived physical age and perceived mental age were rated either as younger, the same or older in comparison with subject's chronological age. Death dates were received from the official register of the province of Central Finland. Confounders used were chronological…
Co-morbidity of malnutrition with falciparum malaria parasitaemia among children under the aged 6–59 months in Somalia: a geostatistical analysis
2018
Background Malnutrition and malaria are both significant causes of morbidity and mortality in African children. However, the extent of their spatial comorbidity remains unexplored and an understanding of their spatial correlation structure would inform improvement of integrated interventions. We aimed to determine the spatial correlation between both wasting and low mid upper arm circumference (MUAC) and falciparum malaria among Somalian children aged 6–59 months. Methods Data were from 49 227 children living in 888 villages between 2007 to 2010. We developed a Bayesian geostatistical shared component model in order to determine the common spatial distributions of wasting and falciparum mal…
