Background: Cardiovascular diseases (CVDs) pose significant global health challenges, with genetics increasingly recognised as a key factor alongside traditional risk factors. This presents an opportunity for general practitioners (GPs) to refine their approaches.

Objective: This article explores the impact of genetics on CVDs and its implications for GPs. It discusses monogenic disorders like inherited cardiomyopathies and polygenic risks, as well as pharmacogenetics, aiming to enhance risk assessment and personalised care.

Discussion: Monogenic disorders, driven by single gene mutations, exhibit predictable inheritance patterns, including inherited cardiomyopathies and channelopathies such as Long QT syndrome. Polygenic risks involve multiple genetic variants influencing CVD susceptibility, addressed through polygenic risk scores for precise risk assessment. Pharmacogenetics tailor drug interventions based on genetic profiles, though challenges like accessibility and ethical considerations persist. Integrating genetics into cardiovascular care holds promise for alleviating the global CVD burden and improving patient outcomes.

Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose.

Introduction: Ireland's Health Service Executive is developing a new national integrated low back pain (LBP) pathway spanning primary and secondary care to improve LBP healthcare. Clinical pathways are frequently employed to optimise clinical outcomes and resource use but are challenging to implement. Context-specific implementation planning, leveraging implementation science and its conceptual frameworks, should inform successful implementation.

Healthcare users' evaluation of general practice - a survey among Danish men aged 45 to 70 years.

BJGP Open

January 2025

Department of Clinical Research, University of Southern Denmark and Open Patient data Explorative Network, Odense University Hospital, Odense, Denmark.

Background: Knowledge about healthcare users' evaluation of general practice is relatively limited.

Aim: We aimed to investigate evaluations in Danish men of general practice healthcare and of different aspects of general practitioners' (GPs) communication with patients.

Design & Setting: Secondary analyses of data from a web-based survey in 6756 Danish men aged 45-70 years (30% response rate) using municipality-level information from registries, self-reported sociodemographic data, personality characteristics, and five-point Likert scale evaluations of healthcare and communication in general practice.

Genetic factors shaping the plasma lipidome and the relations to cardiometabolic risk in children and adolescents.

EBioMedicine

January 2025

Novo Nordisk Foundation Center for Basic Metabolic Research, Faculty of Health and Medical Sciences, University of Copenhagen, Denmark. Electronic address:

Background: Lipid species are emerging as biomarkers for cardiometabolic risk in both adults and children. The genetic regulation of lipid species and their impact on cardiometabolic risk during early life remain unexplored.

Methods: Using mass spectrometry-based lipidomics, we measured 227 plasma lipid species in 1149 children and adolescents (44.
