As new late-onset Alzheimer's disease (LOAD) genetic risk loci are identified and brain cell-type specific omics data becomes available, there is an unmet need for a bioinformatics framework to prioritize genes and variants for testing in single-cell molecular profiling experiments and validation using disease models and gene editing technologies. Prior work has characterized and prioritized active enhancers located in LOAD-genome-wide association study (GWAS) regions and their potential interactions with candidate genes. The current study extends this work by focusing on single nucleotide polymorphisms (SNPs) within these LOAD enhancers and their impact on altering transcription factor (TF) binding. The proposed bioinformatics pipeline progresses from SNPs located in LOAD-GWAS regions to a filtered set of candidate regulatory SNPs that have a predicted strong effect on TF binding.

Active enhancers within LOAD-associated regions were identified and SNPs located in the enhancers were catalogued. SNPs that multi-omics assays and gene editing.
This study provides a framework to catalogue noncoding variations in enhancers located in LOAD-GWAS loci and characterize their likelihood to perturb TF binding. The approach integrates multiple data types to characterize and prioritize SNPs for putative regulatory function using single-cell multi-omics assays and gene editing.
Individuals in the Alzheimer's disease (AD) continuum with mild cognitive impairment (prodromal AD) are at increased risk to develop dementia. Still, underlying pathophysiological processes remain unclear. We studied whether cerebrospinal fluid (CSF) proteome changes are related to time to clinical progression in prodromal AD.

We measured 671 CSF proteins in 49 prodromal AD individuals (67±7 years old, 22 [45%] female) from the Amsterdam Dementia Cohort. Associations of protein levels with time to dementia onset were tested with Cox regression models, followed by biological pathway enrichment analysis.

Eighteen (36%) individuals developed dementia during follow-up. In total, 128 (98%) proteins were associated with a 1.4- to 17-fold increased risk of progression to dementia (all
<.05). These proteins showed enrichment for immune system processes, signal transduction, neuronal death, and neurodevelopmental biology.

CSF proteome changes related to rate of progression to dementia can be detected in prodromal AD, providing more insight into processes involved in early AD pathophysiology.

The bridging integrator 1(
rs744373 risk polymorphism has been linked to increased [
F]AV1451 signal in non-demented older adults (ie., mild cognitive impairment [MCI] plus cognitively normal [CN] individuals). However, the association of
with in vivo tau, amyloid beta (Aβ) burden, and cognitive impairment in the asymptomatic stage of Alzheimer's disease (AD) remains unknown.

The
effect on [
F]AV1451 binding was evaluated in 59 cognitively normal (CN) participants (39% apolipoprotein E [
ε4]) from the Flemish Prevent AD Cohort KU Leuven (F-PACK), as well as in 66 Alzheimer's Disease Neuroimaging Initiative (ADNI) CN participants, using voxelwise and regional statistics. For comparison, 52 MCI patients from ADNI were also studied.

Forty-four percent of F-PACK participants were
rs744373 risk-allele carriers, 21% showed high amyloid burden, and 8% had elevated [
F]AV1451 binding. In ADNI, 53% and 50% of CNs and MCIs, respectively, carried the
rs744373 risk-allele. Amyloid positivity was sociation between BIN1 rs744373 risk-allele and elevated [18F]AV1451 signal in CN older adults or MCI. Numerically higher [18F]AV1451 binding was observed, however, in the MCI BIN1 risk-allele group, indicating that the previously reported positive effect may be confounded by group. Therefore, when studying how the BIN1 risk polymorphism influences AD pathogenesis, a distinction should be made between asymptomatic, MCI, and dementia stages of AD.We developed and evaluated an automatically extracted measure of cognition (semantic relevance) using automated and manual transcripts of audio recordings from healthy and cognitively impaired participants describing the Cookie Theft picture from the Boston Diagnostic Aphasia Examination. We describe the rationale and metric validation. We developed the measure on one dataset and evaluated it on a large database (>2000 samples) by comparing accuracy against a manually calculated metric and evaluating its clinical relevance. The fully automated measure was accurate (r = .84), had moderate to good reliability (intra-class correlation = .73), correlated with Mini-Mental State Examination and improved the fit in the context of other automatic language features (r = .65), and longitudinally declined with age and level of cognitive impairment. This study demonstrates the use of a rigorous analytical and clinical framework for validating automatic measures of speech, and applied it to a measure that is accurate and clinically relevant.
Projected dementia incidence in Latin America and the Caribbean for the next decades is overwhelming. Access to local data, stratified by sex, is imperative for planning precise dementia-prevention strategies.

We analyzed the individual and overall weighted population attributable fraction (PAF) of nine modifiable risk factors for dementia, in dementia-free subjects ≥45-years-old, using the 2016-2017 Chilean National Health Survey.

The overall weighted PAF for modifiable risk factors was 45.8% (42.2% to 49.3%). Variables with the highest PAF were lower education, high blood pressure, hearing loss, and obesity. Women showed a greater overall weighted PAF 50.7% (45.3% to -56.1%), compared to men 40.2% (35.4% to 45.0%), driven by a higher PAF for physical inactivity and depression in women.

The PAF for modifiable risk factors for dementia in Chile is higher than in previous world reports, due to a greater prevalence of cardiovascular risk factors. https://www.selleckchem.com/products/SU11274.html Women have a higher potential for dementia prevention.

The proportion of dementia associated to modifiable risk factors in Chile is 45.8%.The main modifiable risk factors are high blood pressure, obesity, and hearing loss.Women had a greater prevalence of physical inactivity and depression than men.Chile had a greater prevalence of metabolic risk factors than other world regions.

Among vascular risk factors we hypothesized that an increased prevalence of diabetes in Hispanics would be associated with greater white matter hyperintensity (WMH) volume, which may contribute to cognitive decline.

A total of 1318 participants (60% female; 49% Hispanic, 51% non-Hispanic White; age 66.2±8.9 years) underwent clinical evaluation and brain magnetic resonance imaging (MRI). WMH volume associations were assessed with age, sex, and ethnicity and then with vascular risk factors in a selective regression model.

WMH volume was greater with older age (
<.0001), Hispanic ethnicity (
=.02), and female sex (
=.049). WMH volume was best predicted by age, diastolic blood pressure, hypertension history, hemoglobin A1c (HbA1c), white blood cell count, and hematocrit (
<.01 for all). Elevated HbA1c was associated with greater WMH volume among Hispanics (parameter estimate 0.08±0.02,
<.0001) but not non-Hispanic Whites (parameter estimate 0.02±0.04,
=.5).

WMH volume was greater in Hispanics, which may be partly explained by increased WMH volume related to elevated HbA1c among Hispanics but not non-Hispanic Whites.

Blood metabolomics-based biomarkers may be useful to predict measures of neurocognitive aging.

We tested the association between 707 blood metabolites measured in 1451 participants from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), with mild cognitive impairment (MCI) and global cognitive change assessed 7 years later. We further used Lasso penalized regression to construct a metabolomics risk score (MRS) that predicts MCI, potentially identifying a different set of metabolites than those discovered in individual-metabolite analysis.

We identified 20 metabolites predicting prevalent MCI and/or global cognitive change. Six of them were novel and 14 were previously reported as associated with neurocognitive aging outcomes. The MCI MRS comprised 61 metabolites and improved prediction accuracy from 84% (minimally adjusted model) to 89% in the entire dataset and from 75% to 87% among apolipoprotein E ε4 carriers.

Blood metabolites may serve as biomarkers identifying individuals at risk for MCI among US Hispanics/Latinos.

This study aims to determine whether newly introduced biomarkers Visinin-like protein-1 (VILIP-1), chitinase-3-like protein 1 (YKL-40), synaptosomal-associated protein 25 (SNAP-25), and neurogranin (NG) in cerebrospinal fluid are useful in evaluating the asymptomatic and early symptomatic stages of Alzheimer's disease (AD). It further aims to shed new insight into the differences between stable subjects and those who progress to AD by associating cerebrospinal fluid (CSF) biomarkers and specific magnetic resonance imaging (MRI) regions with disease progression, more deeply exploring how such biomarkers relate to AD pathology.

We examined baseline and longitudinal changes over a 7-year span and the longitudinal interactions between CSF and MRI biomarkers for subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI). We stratified all CSF (140) and MRI (525) cohort participants into five diagnostic groups (including converters) further dichotomized by CSF amyloid beta (Aβ) status. Linear mixed molume. These CSF biomarkers should be used in assessing the characterization of the AD progression.
Vaccines against COVID-19 play a prominent role in the policies enacted to combat the pandemic. However, vaccination rates are lowest among adolescents and young adults. Therefore, research on younger individuals is needed to provide a deeper understanding of social disparities and the motives behind vaccination intentions.

This study draws on a sample (N=4079) of German high school students and graduates. Based on cross-sectional data from March to July 2021 and linear regression models, which are conditioned on personality, risk preferences, and trust, the study analyses social disparities (i.e., gender, parental education and migration background) in vaccination intentions.

We do not find heterogeneity by gender. Individuals with low-educated parents and a migration background indicate below-average levels of vaccination intention. Differences in solidarity beliefs entirely explain the heterogeneity between individuals with low-educated parents and those with high-educated parents. While differences in beliefs explain a substantial part of the heterogeneity in vaccination intentions, cultural and monetary resources also constitute an important source of difference in vaccination intentions between individuals with and without a migration background.
