Early Alzheimer´s disease blood biomarkers are associated with a higher risk for postoperative long‐term cognitive decline: Insights from the FINDERI study

open access: yesAlzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract BACKGROUND The study aim is to investigate whether blood biomarkers (BBMs) of Alzheimer's disease (AD) pathology are associated with postoperative cognitive dysfunction (POCD) after cardiac surgery. METHODS Cognitive performance was assessed before and 12 months postoperatively using the Montreal Cognitive Assessment (MoCA) and categorized ...

Comparison of In‐Gel and SP3 Based Sample Preparation Protocols for LC‐MS/MS Based Proteomics

open access: yesPROTEOMICS, Volume 26, Issue 7, Page 6-16, July 2026.
ABSTRACT Sensitivity, robustness, and reproducibility of sample preparation are main determinants of data quality in bottom‐up mass spectrometry‐based proteomics. To this end, in‐gel protein clean‐up and digestion has been used for decades and is characterized by its robustness and compatibility with harsh lysis conditions.

Prevalence of high‐risk plasma p‐tau217 levels and 5‐year transition of risk status in 70‐year‐olds

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION High‐risk plasma p‐tau217 levels predict amyloid‐β pathology in Alzheimer's disease, but little is known about the prevalence and temporal dynamics in the general population. METHODS Participants from the Gothenburg H70 Birth Cohort Study in Sweden were examined (n = 1157) and re‐examined after 5–7 years (n = 771).

Development and validation of MethylCog, a blood DNA methylation proxy for cognition

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Heterogeneity in cognitive ability increases with age and predicts mild cognitive impairment (MCI) and dementia, but scalable blood‐based biomarkers are lacking. We developed and validated MethylCog, a parsimonious DNA methylation (DNAm) marker of general cognitive ability (g).

Reproducible quantitative proteotype data matrices for systems biology

open access: yesMolecular Biology of the Cell, 2015
Historically, many mass spectrometry–based proteomic studies have aimed at compiling an inventory of protein compounds present in a biological sample, with the long-term objective of creating a proteome map of a species. However, to answer fundamental questions about the behavior of biological systems at the protein level, accurate and unbiased ...

Usage and positivity rates of Alzheimer's disease biomarkers in a memory clinic

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Usage of biomarker tests for Alzheimer's disease pathology and rates of positivity were assessed at the Washington University Memory Diagnostic Center. METHODS Patients who underwent at least one biomarker test for clinical purposes between June 2021 and March 2025 were included (n = 1136). Data were retrospectively extracted from

Precision medicine for Alzheimer's disease in Down syndrome

open access: yesAlzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Down syndrome (DS) exhibits a genetic form of Alzheimer's disease (AD). We used a blood‐based proteomic algorithm to predict cognitive status, treatment responders, and change to vitamin E in DS adults from a completed clinical trial, “Vitamin E in Aged Persons with Down Syndrome,” which originally showed no significant cognitive ...

Penalized Estimation in Finite Mixtures of Multivariate Regression Models via the EM‐PGM Algorithm

open access: yesStatistics in Medicine, Volume 45, Issue 8-9, April 2026.
ABSTRACT In many areas of medical and life sciences research, multiple diagnostic criteria and phenotypic outcomes are assessed simultaneously to characterize diseases and biological traits. These multivariate outcomes are often associated with high‐dimensional covariates and subject to underlying population heterogeneity, presenting challenges for ...
