Circulating vitamin D in relation to cancer incidence and survival of the head and neck and oesophagus in the EPIC cohort

Experimental and epidemiological data suggest that vitamin D play a role in pathogenesis and progression of cancer, but prospective data on head and neck cancer (HNC) and oesophagus cancer are limited. The European Prospective Investigation into Cancer and Nutrition (EPIC) study recruited 385,747 participants with blood samples between 1992 and 2000. This analysis includes 497…

Parity, breastfeeding and risk of coronary heart disease: A pan-European case–cohort study

Objective There is uncertainty about the direction and magnitude of the associations between parity, breastfeeding and the risk of coronary heart disease (CHD). We examined the separate and combined associations of parity and breastfeeding practices with the incidence of CHD later in life among women in a large, pan-European cohort study. Methods Data were used…

Main nutrient patterns and colorectal cancer risk in the European Prospective Investigation into Cancer and Nutrition study

Background: Much of the current literature on diet–colorectal cancer (CRC) associations focused on studies of single foods/nutrients, whereas less is known about nutrient patterns. We investigated the association between major nutrient patterns and CRC risk in participants of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: Among 477 312 participants, intakes of 23…

A method for sensitivity analysis to assess the effects of measurement error in multiple exposure variables using external validation data

Background: Measurement error in self-reported dietary intakes is known to bias the association between dietary intake and a health outcome of interest such as risk of a disease. The association can be distorted further by mismeasured confounders, leading to invalid results and conclusions. It is, however, difficult to adjust for the bias in the association when there is…

Evaluación de una estrategia formativa entre iguales en fibromialgia. Un análisis de género

La fibromialgia es una enfermedad crónica altamente feminizada que requiere mayor autonomía y autoeficiencia en el manejo de los cuidados. Objetivo: evaluar, desde una perspectiva de género, la estrategia formativa de pacientes con fibromialgia de la Escuela de Pacientes, basada en la formación “entre iguales”. Método: estudio cuantitativo, con diseño cuasiexperimental pretest- postest, con 600 participantes con fibromialgia. Se…

Cross-cancer genome-wide analysis of lung, ovary, breast, prostate and colorectal cancer reveals novel pleiotropic associations

Identifying genetic variants with pleiotropic associations can uncover common pathways influencing multiple cancers. We took a two-staged approach to conduct genome-wide association studies for lung, ovary, breast, prostate and colorectal cancer from the GAME-ON/GECCO Network (61,851 cases, 61,820 controls) to identify pleiotropic loci. Findings were replicated in independent association studies (55,789 cases, 330,490 controls). We…
