Cerebrospinal Fluid (CSF) Proteomic Signature in Preclinical and Clinical AD: Role of Adhesion Molecules.

Background: Although Amyloid-beta and Tau are the hallmarks of Alzheimer's Disease (AD), other protein pathways such as endothelial dysfunction may be involved and may precede cognitive symptoms. Our objective was to characterize the cerebrospinal fluid (CSF) proteomic profiles focusing on cardiometabolic-related protein pathways in individuals on the AD spectrum.

Methods: We performed CSF and plasma-targeted proteomics (276 proteins) from 354 participants of the Brain Stress Hypertension and Aging Program (BSHARP), of which 8% had preclinical AD, and 24% had MCI due to AD.

Impact of frailty and comorbidity on initial response to lung cancer screening invitation and low-dose CT screening uptake: Findings from the Yorkshire Lung Screening Trial.

Background: Low-dose computed tomography screening reduces lung cancer-specific mortality in high-risk individuals. Lung cancer risk factors overlap with comorbid diseases, highlighting the significance of frailty and comorbidities for lung cancer screening (LCS). Here, we describe the prevalence of frailty and comorbidity in those invited for LCS and evaluate their associations with response to telephone risk assessment invitation and subsequent uptake of LCS.

NHS-Galleri trial: Enriched enrolment approaches and sociodemographic characteristics of enrolled participants.

Background/aims: Certain sociodemographic groups are routinely underrepresented in clinical trials, limiting generalisability. Here, we describe the extent to which enriched enrolment approaches yielded a diverse trial population enriched for older age in a randomised controlled trial of a blood-based multi-cancer early detection test (NCT05611632).

Methods: Participants aged 50-77 years were recruited from eight Cancer Alliance regions in England.

General Practice chest x-ray rate is associated with earlier lung cancer diagnosis and reduced all-cause mortality: a retrospective observational study.

Background: Evidence on whether general practice rates of investigation in symptomatic patients using chest x-ray (CXR) affects outcomes is equivocal.

Aim: Determine if there is an association between rates of general practice (GP) requested CXR and lung cancer outcomes.

Design And Setting: Retrospective observational study (England) Methods: Cancer registry data for patients diagnosed with lung cancer 2014-2018 was linked to data on GP CXRs 2013-2017.

Prospective Evaluation of Lung Cancer Screening Eligibility Criteria and Lung Cancer Detection in the Yorkshire Lung Screening Trial.

Introduction: Low-dose computed tomography screening for lung cancer reduces lung cancer mortality, but there is a lack of international consensus regarding the optimal eligibility criteria for screening. The Yorkshire Lung Screening Trial was designed to evaluate lung cancer screening (LCS) implementation, and a primary objective was prospective evaluation of three predefined eligibility criteria.

Methods: Individuals who had ever smoked, aged 55 to 80 years, who responded to written invitation, underwent telephone risk assessment and if eligible by at least one criterion (PLCO ≥ 1.
