Machine learning for stroke in heart failure with reduced ejection fraction but without atrial fibrillation: A post-hoc analysis of the WARCEF trial.
The prediction of ischaemic stroke in patients with heart failure with reduced ejection fraction (HFrEF) but without atrial fibrillation (AF) remains challenging. Our aim was to evaluate the performance of machine learning (ML) in identifying the development of ischaemic stroke in this population. ⋯ Machine-learning models can be useful in identifying incident ischaemic strokes in patients with HFrEF but without AF. CrCl, BUN and warfarin use were the key features.

Review Meta AnalysisVascular endothelial growth factor in inflammatory bowel disease: A systematic review and meta-analysis.
Vascular endothelial growth factor (VEGF) is linked to inflammation and angiogenesis, indicating a possible role in inflammatory bowel disease (IBD) and its main clinical manifestations, Crohn's disease (CD) and ulcerative colitis (UC). This systematic review and meta-analysis investigated studies assessing circulating VEGF concentrations in IBD patients and healthy controls, considering the effect of IBD type, sample type and geographical location. ⋯ VEGF concentrations are elevated in IBD patients, with variations by disease type, sample type and geography. However, VEGF is not a reliable marker of disease activity. Future research should standardize methods and explore regional influences to enhance VEGF's clinical utility as a biomarker of IBD.

Randomized Controlled TrialSexual dimorphism in exercise-induced response on steroid hormones to a 24-week supervised concurrent training intervention.
Steroid hormones are key mediators of adaptative responses to exercise, a stimulus that may concurrently affect their blood concentrations. However, the chronic endocrine adaptations and whether these potential changes are dependent on exercise intensity remain undetermined. Moreover, it is also unknown if the exercise-induced effects on steroid hormonal status are related to the participant' sex. ⋯ Our 24-week supervised concurrent training intervention showed no significant changes in steroid hormone levels. However, a significant decrement of T/C ratio was observed only in women, indicating a sexual dimorphism in the effect on T/C ratio.

Genome-wide methylation profiling of maternal cell-free DNA using methylated DNA sequencing (MeD-seq) indicates a placental and immune-cell signature.
Placental-originated cell-free DNA (cfDNA) provides unique opportunities to study (epi)genetic placental programming remotely, but studies investigating the cfDNA methylome are scarce and usually technologically challenging. Methylated DNA sequencing (MeD-seq) is well compatible with low cfDNA concentrations and has a high genome-wide coverage. We therefore aim to investigate the feasibility of genome-wide methylation profiling of first trimester maternal cfDNA using MeD-seq, by identifying placental-specific methylation marks in cfDNA. ⋯ MeD-seq can detect (novel) genome-wide placental DNA methylation marks and determine fetal sex in maternal cfDNA. Our results indicate a placental and immune-cell contribution to the pregnancy-specific cfDNA methylation signature. This study supports future research into maternal cfDNA methylation.

Residual risk prediction in anticoagulated patients with atrial fibrillation using machine learning: A report from the GLORIA-AF registry phase II/III.
Although oral anticoagulation decreases the risk of thromboembolism in patients with atrial fibrillation (AF), a residual risk of thrombotic events still exists. This study aimed to construct machine learning (ML) models to predict the residual risk in these patients. ⋯ ML algorithms can improve the prediction of residual risk of anticoagulated AF patients compared to clinical risk factor-based scores.
