Atrial fibrillation versus. atrial myopathy in thrombogenesis: Two sides of the same coin?

Trends Cardiovasc Med

January 2025

Liverpool Centre for Cardiovascular Science at University of Liverpool, Liverpool John Moores University and Liverpool Heart and Chest Hospital, Liverpool, United Kingdom; Department of Clinical Medicine, Aalborg University, Aalborg, Denmark; Medical University of Bialystok, Bialystok, Poland.

Atrial fibrillation (AF) and atrial myopathy are recognized contributors to cardiovascular morbidity, particularly ischemic stroke. AF poses an elevated risk of thrombogenesis due to irregular heart rhythm leading to blood stasis and clot formation. Atrial myopathy, marked by structural and functional alterations in the atria, is emerging as a crucial factor influencing thromboembolic events, independently of AF.

Swiss Tropical and Public Health Institute, Allschwil, Switzerland; Department of Public Health, University of Basel, Basel, Switzerland. Electronic address:

Background: The independent and interrelated long-term effects of the exposome such as air pollution, greenness, and ambient temperature on lung function are not well understood, yet relevant in the light of climate change.

Methods: Pre-bronchodilation FEV1 from five mature birth cohorts (N = 4724) and three adult cohorts (N = 6052) from five European countries were used to assess cross-sectional associations with air pollution, greenness, and ambient temperature, assigned to their residential address. All two-way interactions and square terms were a priori included in building the final elastic net regression model.

Purpose: Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental condition that affects approximately 5% of the pediatric population, with increased prevalence among those with type 1 diabetes (T1D). Reports suggest that unrecognized and untreated ADHD impairs T1D control and that ADHD may be underdiagnosed in the Polish population. The International Society for Pediatric and Adolescent Diabetes recommends neurodevelopmental assessments in children with T1D, but specific guidelines on procedures and implementation are lacking.

The Potential of Neonatal Organ Donation in Central Sweden.

Cell Transplant

January 2025

Department of Clinical Science, Intervention and Technology, Karolinska Institutet, Stockholm, Sweden.

Pediatric organ transplant recipients have a higher risk for wait list mortality due to the scarcity of size matched organs. Neonatal organ donation could potentially ameliorate the discrepancy but is currently not implemented in Sweden. This study aims to evaluate the potential of neonatal organ donation in central Sweden using a standardized protocol with organ specific criteria.

A Haplotype GWAS in Syndromic Familial Colorectal Cancer.

Int J Mol Sci

January 2025

Department of Molecular Medicine and Surgery, Karolinska Institutet, 17176 Stockholm, Sweden.

A previous genome-wide association study (GWAS) in colorectal cancer (CRC) patients with gastric and/or prostate cancer in their families suggested genetic loci with a shared risk for these three cancers. A second haplotype GWAS was undertaken in the same colorectal cancer patients and different controls with the aim of confirming the result and finding novel loci. The haplotype GWAS analysis involved 685 patients with colorectal cancer cases and 1642 healthy controls from Sweden.

Exploring Potential Complement Modulation Strategies for Ischemia-Reperfusion Injury in Kidney Transplantation.

Antioxidants (Basel)

January 2025

Nephrology, Dialysis and Transplantation Unit, Advanced Research Center on Kidney Aging (A.R.K.A.), Department of Medical and Surgical Sciences, University of Foggia, 71122 Foggia, Italy.

The complement system plays a crucial role in regulating the inflammatory responses in kidney transplantation, potentially contributing to early decline in kidney function. Ischemia-reperfusion injury (IRI) is among the factors affecting graft outcomes and a primary contributor to delayed graft function. Complement activation, particularly the alternative pathway, participates in the pathogenesis of IRI, involving all kidney compartments.

There is emerging evidence of an inverse association between prostatic inflammation (PI) and prostate cancer (PCa) diagnosis and outcome. The Irani score, a validated system that scores PI according to the grade of stromal infiltration (Irani G) and the aggressiveness of glandular infiltration (Irani A), has indeed been found to be inversely associated with PCa diagnosis and outcome, but the presence of two categories (G and A) makes the performance of this score suboptimal. This study aimed to determine whether a novel prostatic inflammation score (PIS) that combines Irani G and A scores better defined the risk of being diagnosed with PCa at prostate biopsy (PBx).

Obesity strongly increases the risk of cardiometabolic diseases, yet the underlying mediators of this relationship are not fully understood. Given that obesity strongly influences circulating protein levels, we investigated proteins mediating the effects of obesity on coronary artery disease, stroke and type 2 diabetes. By integrating two-step proteome-wide Mendelian randomization, colocalization, epigenomics and single-cell RNA sequencing, we identified five mediators and prioritized collagen type VI α3 (COL6A3).
