Background：Neurological deterioration following acute ischemic stroke (AIS) is a common clinical phenomenon associated with poor clinical outcomes. However, neurological deterioration can be attributed to diverse mechanisms in different clinical contexts. Further, there is still a lack of standard and well-recognized definitions of neurological deterioration, which compounds the complexities and challenges of its early identification and management of neurological deterioration.

During the last few years, significant pathophysiological differences between heart failure (HF) patients with "normal" ejection fraction (EF) (50% to 64%) and those with supra-normal EF (≥65%) have been highlighted. However, these distinct EF phenotypes have been poorly investigated in elderly patients aged ≥70 y. Accordingly, the present study aimed at assessing the clinical and echocardiographic characteristics of a retrospective cohort of elderly HFpEF patients (aged ≥ 70 y), categorized on the basis of "normal" EF (50 to 64%) or "supra-normal" EF (≥65%).

Lower risk (LR) myelodysplastic syndromes (MDS) are heterogeneous hematopoietic stem and progenitor disorders caused by the accumulation of somatic mutations in various genes including epigenetic regulators that may produce convergent DNA methylation patterns driving specific gene expression profiles. The integration of genomic, epigenomic, and transcriptomic profiling has the potential to spotlight distinct LR-MDS categories on the basis of pathophysiological mechanisms. We performed a comprehensive study of somatic mutations and DNA methylation in a large and clinically well-annotated cohort of treatment-naive patients with LR-MDS at diagnosis from the EUMDS registry (ClinicalTrials.

Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder affecting women of childbearing age, and we aimed to reveal its underlying molecular mechanisms. Gene expression profiles from GSE138518 and GSE155489, and single-cell RNA sequencing (scRNA-seq) data from PRJNA600740 were collected and subjected to bioinformatics analysis to identify the complex molecular mechanisms of PCOS. The expression of genes was detected by RT-qPCR.

Objective: Despite the well-established increased risk of cardiovascular mortality in individuals with bipolar disorder (BD), prevention and treatment of cardiovascular risk factors and diseases have been largely overlooked in this population. This manuscript reviews the pathophysiological basis of the connection between BD and cardiovascular diseases, highlighting their shared mechanisms, reciprocal interactions, and relevant prevention and treatment strategies.
Methods: For this narrative review, a search was carried out on PubMed using the keywords bipolar disorder, cardiovascular diseases, and cardiovascular risk factors.
