Association between Polyphenol Intake and Breast Cancer Risk by Menopausal and Hormone Receptor Status

[EN] There is limited evidence of phenolic compounds acting as protective agents on several cancer types, including breast cancer (BC). Nevertheless, some polyphenol classes have not been investigated and there is a lack of studies assessing the effect on menopausal status and hormone receptor status as influenced by these compounds. The objective of this study is to evaluate the association between the intake of all polyphenol classes in relation to the BC risk by menopausal and hormone receptor status. We used data from a population-based multi-case-control study (MCC-Spain) including 1472 BC cases and 1577 controls from 12 different regions of Spain. The odds ratios (ORs) with 95% CI were calculated using logistic regression of mixed effects by quartiles and log2 of polyphenol intakes (adjusted for the residual method) of overall BC, menopausal and receptor status. No associations were found between total intake of polyphenols and BC risk. However, inverse associations were found between stilbenes and all BC risk (ORQ4 vs. Q1: 0.70, 95%CI: 0.56–0.89, Ptrend = 0.001), the consumption of hydroxybenzaldehydes (ORQ4 vs. Q1: 0.75, 95%CI: 0.59–0.93, Ptrend = 0.012 ) and hydroxycoumarins (ORQ4 vs. Q1: 0.73, 95%CI: 0.57–0.93; Ptrend = 0.005) were also inversely associated. The intake of stilbenes, hydroxybenzaldehydes and hydroxycoumarins can contribute to BC reduction risk on all menopausal and receptor statusesS

Dietary Inflammatory Index, Dietary Non-Enzymatic Antioxidant Capacity, and Colorectal and Breast Cancer Risk (MCC-Spain Study)

[EN] Inflammation and antioxidant capacity have been associated with colorectal and breast cancer. We computed the dietary inflammatory index (DII®), and the total dietary non-enzymatic antioxidant capacity (NEAC) and associated them with colorectal and breast cancer risk in the population-based multi case-control study in Spain (MCC-Spain). We included 1852 colorectal cancer and 1567 breast cancer cases, and 3447 and 1486 population controls, respectively. DII score and NEAC were derived using data from a semi-quantitative validated food frequency questionnaire. Unconditional logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (95%CI) for energy-adjusted DII (E-DII), and a score combining E-DII and NEAC. E-DII was associated with colorectal cancer risk (OR = 1.93, highest quartile versus lowest, 95%CI:1.60–2.32; p-trend: 0.10). The combined score of high E-DII scores and low antioxidant values were associated with colorectal cancer risk (OR = 1.48, highest quartile versus lowest, 95%CI: 1.26–1.74; p-trend: <0.001), but not breast cancer. This study provides evidence that a pro-inflammatory diet is associated with increased colorectal cancer risk while findings for breast cancer were less consistent.S

Decisions of refusal Intensive Care Units' admission as a measure of limitation of life support treatments: geographical variability in Spain

From a post hoc analysis of the ADENI-UCI study (multicenter, observational, cohort, prospective study, with a follow-up period of 13 months, in 62 Intensive Medicine Services in Spain. geographical differences in the reason for denial of income in UCI as a LTSV measure are analyzed. A total of 2284 with an average age of 75.25 (12.45) years were included. 59.43% male. By means of multinominal regression adjusted by age, sex, APACHE and SOFA, was evident (by choosing the northern for reference) that age in the south was a less significantly exposed reason (OR: 0.48 (IC95%: 0.35-0.65). p
