Influenza vaccination reduces dementia risk: A systematic review and meta-analysis
2021
Animal models have indicated that influenza vaccination may prevent or delay the onset of dementia. However, the epidemiological evidence in human beings is still limited. Given this background, this systematic review and meta-analysis aimed to summarize the current state of the art of observational studies investigating the association between influenza vaccination and the risk of dementia. We searched Scopus and Pubmed/Medline until 24 September 2021 for studies investigating the risk of dementia by influenza vaccination status. After adjustment for potentially important confounding variables, data were reported as risk ratios (RRs) with 95% confidence intervals (CIs). Among 273 articles …
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…
Management and prognosis of pancreatic cancer over a 30-year period.
2009
BACKGROUND: The aim of this study was to report on changes in the diagnostic assessment, patterns of care and survival over time for pancreatic cancers. METHODS: A total of 2986 cases of pancreatic cancer from the Digestive Cancer Registry of Burgundy (France) over a 30-year period (1976–2005) were considered. Non-conditional logistic regressions were carried out to identify the factors associated with resection for cure and with the use of chemotherapy. A multivariate relative survival analysis was carried out. RESULTS: Diagnostic procedures have changed. Ultrasonography and computed tomography progressively have become the major diagnostic procedures. There was a slight improvement in sta…
European disparities in malignant digestive endocrine tumours survival.
2009
The aim of this study was to report on malignant digestive endocrine tumours (MDET) prognosis in several European countries. We analysed survival data from 19 cancer registries in 12 European countries on 3,715 MDET diagnosed between 1985 and 1994. The overall 5-year survival rate was 47.5%. It was 58.1% for differentiated MDET and 8.1% for small-cell MDET (p < 0.001), 55.9% for patients under 65 and 37.0% for older patients. Survival rates for small intestinal and colorectal were higher than for the other sites. The 5-year relative survival rates were 60.3% in Northern Europe, 53.6% in Western Continental Europe, 42.5% in the UK, 37.6% in Eastern Europe (p < 0.001). Among well-differentiat…
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…
Nonsyndromic cleft lip and palate, gastric cancer and tooth agenesis
2018
Background To determine the frequency of nonsyndromic cleft lip and/or palate (NSCL/P) in first-degree relatives and to analyze the prevalence of tooth agenesis in patients with gastric cancer. Material and Methods This cross-sectional, observational, case-control study included 798 patients attended at hospital Santa Casa in Montes Claros, Minas Gerais and Alfa Institute of Gastroenterology of the Federal University of the Minas Gerais. Information on basic demographic data and tooth agenesis of both groups and their family history of NSCL/P in first-degree relatives were evaluated. The collected information was stored in a database and analyzed using statistical program SPSS® version 21.0…
