Results of studies on perfluoroalkyl substances (PFASs) and thyroid hormones (THs) are heterogeneous, and the mechanisms underlying the action of PFASs to target THs have not been fully characterized. We examined the relation between first-trimester maternal PFAS and TH levels and the role played by polymorphisms in the iodothyronine deiodinase 1 (DIO1) and 2 (DIO2)…
Background Bisphenol A (BPA) is an endocrine disruptor that it is present in numerous products of daily use. The aim of this study was to assess the potential association of serum BPA concentrations and the risk of incident breast and prostate cancer in a sub-cohort of the Spanish European Prospective Investigation into Cancer and Nutrition…
(1) Background: The aim of this study was (i) to analyze problems faced by informal caregivers in three areas of their life: health, work and finances, and family and social relationships, (ii) to investigate the main determinants of these problems, and (iii) to explore differences between men and women. (2) Methods: The study population consisted…
This manuscript describes the rationale and protocol of a real-world data (RWD) study entitled Health Care and Social Survey (ESSOC, Encuesta Sanitaria y Social). The study’s objective is to determine the magnitude, characteristics, and evolution of the COVID-19 impact on overall health as well as the socioeconomic, psychosocial, behavioural, occupational, environmental, and clinical determinants of…
Dysregulation of tryptophan metabolism has been linked to colorectal tumorigenesis, however, epidemiological studies investigating tryptophan metabolites in relation to colorectal cancer risk are limited. We studied associations of plasma tryptophan, serotonin, and kynurenine with colon cancer risk in two studies with cancer patients and controls, and in one prospective cohort: ColoCare Study (110 patients/153 controls),…
Es el primer día de verano en Omelas. Todo es resplandeciente. La ciudad disfruta de su festival en un ambiente de comunidad cohesionada, alegre y culta. Nada parece ir mal. Omelas solo tiene un inconveniente: para conservar su equilibrio y felicidad es necesario mantener a un niño en la más absoluta pobreza y marginación. Al…
The role of chronic inflammation on breast cancer (BC) risk remains unclear beyond as an underlying mechanism of obesity and physical activity. We aimed to evaluate the association between the inflammatory potential of the diet and risk of BC overall, according to menopausal status and tumour subtypes. Within the European Prospective Investigation into Cancer and…
Background Endometrial cancer is strongly associated with obesity and dysregulation of metabolic factors such as estrogen and insulin signaling are causal risk factors for this malignancy. To identify additional novel metabolic pathways associated with endometrial cancer we performed metabolomic analyses on pre-diagnostic plasma samples from 853 case-control pairs from the European Prospective Investigation into Cancer…
Background Human bisphenol-A (BPA) exposure has been linked to adverse health effects even at low doses, which may be of potential public health concern. Objective To summarize BPA concentrations in general human population and their variability according to sex, geographic area, and analytical method. Methods Systematic review and meta-analysis of studies reporting BPA concentrations in…
Background Alcohol is an established risk factor for several cancers, but modest alcohol-cancer associations may be missed due to measurement error in self-reported assessments. Biomarkers of habitual alcohol intake may provide novel insight into the relationship between alcohol and cancer risk. Methods Untargeted metabolomics was used to identify metabolites correlated with self-reported habitual alcohol intake…
