Polygenic scores for risk of pancreatic ductal adenocarcinoma: evaluation of novel and published models

Artículos Científicos, Cáncer, Igualdad, Investigación, Mujeres EASP

Polygenic risk scores (PRSs) may enhance risk stratification for pancreatic ductal adenocarcinoma (PDAC), but existing models vary widely in design, predictive performance, and cross-ancestry transferability. We developed genome-wide PRSs using Bayesian methods (LDpred2 and PRS-CS) and p value thresholding (PRSice-2) and systematically evaluated these alongside 13 published PRSs to identify models with robust predictive performance…

Policy approach to optimize multiple myeloma treatment sequencing practices

Artículos Científicos

Introduction As a consequence of major therapeutic advances that have transformed multiple myeloma (MM) into a manageable chronic condition, treatment sequencing has become highly complex. According to current practices, novel therapies are predominantly reserved for later disease stages, yet limited evidence suggests that this approach yields optimal long-term outcomes. Understanding the drivers of current practices…

PNS108 Proposal for a Core Evaluation Framework of Value Added Medicines

Artículos Científicos

Objectives Through incremental innovation by repositioning, reformulating and combining of off-patent pharmaceuticals, value added medicines (VAMs) offer potential benefits at affordable R&D costs. Current evaluation frameworks are primarily designed for de novo pharmaceuticals, consequently the mismatch between evidence requirements by public decision-makers and the evidence generated by manufacturers prevents exploiting the full societal benefits of…

Plasma Vitamin C and Type 2 Diabetes: Genome-Wide Association Study and Mendelian Randomization Analysis in European Populations

Artículos Científicos

OBJECTIVE Higher plasma vitamin C levels are associated with lower type 2 diabetes risk, but whether this association is causal is uncertain. To investigate this, we studied the association of genetically predicted plasma vitamin C with type 2 diabetes. RESEARCH DESIGN AND METHODS We conducted genome-wide association studies of plasma vitamin C among 52,018 individuals of European…

Plasma polyphenols associated with lower high-sensitivity C-reactive protein concentrations: a cross-sectional study within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort

Artículos Científicos

Experimental studies have reported on the anti-inflammatory properties of polyphenols. However, results from epidemiological investigations have been inconsistent, and especially studies using biomarkers for assessment of polyphenol intake have been scant. We aimed to characterize the association between plasma concentrations of 35 polyphenol compounds and low-grade systemic inflammation state as measured by high-sensitivity C-reactive protein…

Plasma Non-Enzymatic Antioxidant Capacity (NEAC) in Relation to Dietary NEAC, Nutrient Antioxidants and Inflammation-Related Biomarkers

Artículos Científicos

Background: Little is known about the interlinkages between dietary and plasma non-enzymatic antioxidant capacity (D-NEAC and P-NEAC, respectively) and the body’s antioxidant and inflammation response. Our aim was to explore these associations in 210 participants from two Spanish European Prospective Investigation into Cancer and Nutrition (EPIC) centers. (2) Methods: D-NEAC was estimated using published NEAC…

Plasma microRNAs as biomarkers of pancreatic cancer risk in a prospective cohort study

Artículos Científicos

Non-invasive biomarkers for early pancreatic ductal adenocarcinoma (PDAC) diagnosis and disease risk stratification are greatly needed. We conducted a nested case-control study within the Prospective Investigation into Cancer and Nutrition (EPIC) cohort to evaluate pre-diagnostic microRNAs (miRs) as biomarkers of subsequent PDAC risk. A panel of eight miRs (miR-10a, -10b, -21-3p, -21-5p, -30c, -106b, -155,…

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

Artículos Científicos

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…

Plasma concentrations of persistent organic pollutants and pancreatic cancer risk

Artículos Científicos

Background Findings and limitations of previous studies on persistent organic pollutants (POPs) and pancreatic cancer risk support conducting further research in prospective cohorts. Methods We conducted a prospective case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Participants were 513 pancreatic cancer cases and 1020 matched controls. Concentrations of 22…
