Background: Premenopausal risk-reducing salpingo-oophorectomy (RRSO) in women at high familial risk of ovarian cancer leads to immediate menopause. Although early natural menopause is associated with increased cardiovascular disease risk, evidence on long-term cardiovascular disease risk after early surgical menopause is scarce.

Objectives: We sought to determine the long-term influence of the timing of RRSO on the development of coronary artery calcium (CAC), an established marker for cardiovascular disease risk.

Background: Lung cancer screening (LCS) with low-dose CT (LDCT) reduces lung-cancer-related mortality in high-risk individuals. AI can potentially reduce radiologist workload as first-read-filter by ruling-out negative cases. The feasibility of AI as first reader was evaluated in the European 4-IN-THE-LUNG-RUN (4ITLR) trial, comparing its negative-misclassifications (NMs) to those of radiologists and the impact on referral rates.

Aims: Evidence on the impact of screening for cardiovascular diseases (CVDs) on health-related quality of life (HRQoL) is important for policy decisions about screening implementation and to uncover teachable moments to motivate healthy lifestyle choices. It is unknown whether screening by cardiac computed tomography (CT) scan has a stronger impact on HRQoL than screening by traditional risk prediction models. The study aims to investigate differences in HRQoL across the screening process between participants who were randomized to CVD risk estimation by coronary artery calcium score or Systematic COronary Risk Evaluation.

Objective: To explore associations between general health-related problems and subclinical coronary artery disease (CAD), determined by CT coronary calcium score (CT-CCS), in a general population.

Design: A cross-sectional design.

Setting: This study was performed in a prospective population-based cohort, examining the health and health-related behaviour of individuals living in the Northern Netherlands.

Aim: Lung cancer growth rate influences screening strategies and treatment decisions. This review aims to provide an overview of primary lung cancer growth rate, quantified by volume doubling time (VDT) through computed tomography (CT) measurement.

Methods: Using PRISMA-DTA guideline, PubMed, EMBASE, and Web of Science were searched until March 2024 for studies reporting CT-measured VDT of pathologically confirmed primary lung cancer before intervention.
