Plasma fetuin-A concentration, genetic variation in the AHSG gene and risk of colorectal cancer

Fetuin-A, also referred to as α2-Heremans-Schmid glycoprotein (AHSG), is a liver protein known to inhibit insulin actions. Hyperinsulinemia is a possible risk factor for colorectal cancer; however, the role of fetuin-A in the development of colorectal cancer is unclear. We investigated the association between circulating fetuin-A and colorectal cancer risk in a nested case–control study…

Trends in lung cancer incidence by histologic subtype in the south of Spain, 1985–2012: a population-based study

Purpose To analyze and interpret age- and sex-specific incidence trends of lung cancer in Granada over the period 1985–2012 and to further analyze these trends by histologic subtype. Methods Incidence data were obtained from the population-based cancer registry located in Granada (Southern Spain). All cases with newly diagnosed primary lung cancer over the period 1985–2012…

Polymorphisms of pesticide-metabolizing genes in children living in intensive farming communities

Polymorphisms in genes encoding xenobiotic-metabolizing enzymes (XME) are important parameters accounting for the wide inter-individual variability to environmental exposures. Paraoxonase-1 (PON1), butyrylcholinesterase (BChE) and Cytochrome-P450 constitute major classes of XME involved in the detoxification of pesticide chemicals, in particular organophosphates. This study explored the allelic frequency, linkage disequilibrium and haplotype analysis of ten common polymorphic…

Controversial messages on cancer

A direct connection between certain lifestyle factors and an increased risk of cancer has already been established. Despite well-documented associations, controversial messages on causes of cancer often appear without taking into consideration their impact on the general population. While mainstream coverage of cancer research is clearly welcome, consideration must be given to the risk of…

Main nutrient patterns are associated with prospective weight change in adults from 10 European countries

Purpose Various food patterns have been associated with weight change in adults, but it is unknown which combinations of nutrients may account for such observations. We investigated associations between main nutrient patterns and prospective weight change in adults. Methods This study includes 235,880 participants, 25–70 years old, recruited between 1992 and 2000 in 10 European countries.…
