Metabolic dysfunction-associated steatotic liver disease (MASLD) has been proposed as a new name for the previous non-alcoholic fatty liver disease (NAFLD). There are some differences between MASLD and NAFLD, e.g.

Proteasome inhibitors (PIs), bortezomib, carfilzomib, and ixazomib, are the first-line treatment for multiple myeloma (MM). They inhibit cytosolic protein degradation in cells, which leads to the accumulation of misfolded and malfunctioned proteins in the cytosol and endoplasmic reticulum, resulting in cell death. Despite being a breakthrough in MM therapy, malignant cells develop resistance to PIs via different mechanisms.

Progressive supranuclear palsy (PSP) is a rare, neurodegenerative movement disorder. Together with multiple system atrophy (MSA), Dementia with Lewy bodies (DLB), and corticobasal degeneration (CBD), PSP forms a group of atypical parkinsonisms. The latest diagnostic criteria, published in 2017 by the Movement Disorders Society, classify PSP diagnosis into defined, probable, and possible categories based on clinical examination.

Duchenne muscular dystrophy (DMD) is an X-linked progressive disorder associated with muscle wasting and degeneration. The disease is caused by mutations in the gene that encodes dystrophin, a protein that links the cytoskeleton with cell membrane proteins. The current treatment methods aim to relieve the symptoms of the disease or partially rescue muscle functionality.

N-terminal prohormone of brain natriuretic peptide (NT-proBNP) is a non-active prohormone secreted by ventricular cardiomyocytes into the circulation in response to ventricle overload, mainly due to increased blood volume. The changes in NT-proBNP levels during pregnancy have been investigated in multiple studies. In the case of hypertensive disorders of pregnancy, increased vasoconstriction leads to increased blood pressure and afterload.

According to the World Health Organization's statement, myocarditis is an inflammatory myocardium disease. Although an endometrial biopsy remains the diagnostic gold standard, it is an invasive procedure, and thus, cardiac magnetic resonance imaging has become more widely used and is called a non-invasive diagnostic gold standard. Myocarditis treatment is challenging, with primarily symptomatic therapies.

Article Synopsis
  • Myocarditis is an inflammatory heart disease primarily caused by viruses, and existing diagnostic methods, like endomyocardial biopsy, are invasive and not widely used.
  • Current treatment for viral myocarditis is largely symptomatic, with no clear evidence supporting the effectiveness of therapies like steroids or intravenous immunoglobulins in autoimmune cases, highlighting the need for better diagnostic and treatment options.
  • Recent studies have shown that microRNAs (miRNAs) are involved in regulating heart functions and display altered levels in myocarditis, indicating that manipulating these miRNAs may improve disease outcomes and even aid vaccine development.

Numerous risk factors for atrial fibrillation (AF) progression have been identified. However, the biomarkers mentioned in the guidelines do not have any clinically relevant predictive value. Some research groups investigated the potential utility of galectin-3 (gal-3) as a diagnostic, prognostic, and predictive biomarker in AF.

Article Synopsis
  • - A study explored the potential of soluble urokinase-type plasminogen activator receptor (suPAR) as a biomarker for diagnosing acute coronary syndrome (ACS), highlighting the need for better diagnostic tools in clinical practice.
  • - The researchers conducted a meta-analysis of five studies with 3,417 participants, comparing suPAR levels in patients with ACS to those without, finding significantly higher levels in the ACS group.
  • - The findings suggest that measuring suPAR levels could improve early identification of ACS in emergency room settings, indicating its relevance as a clinical tool.

Aortic stenosis (AS) is the most prevalent primary valve lesion demanding intervention. Two main treatment options are surgical aortic valve replacement or transcatheter aortic valve implantation. There is an unmet need for biomarkers that could predict treatment outcomes and become a helpful tool in guiding Heart Team in the decision-making process.

Article Synopsis
  • * The study assessed the effectiveness of color Doppler ultrasound (DUS) against digital subtraction angiography (DSA) and magnetic resonance angiography (MRA) in monitoring patients post-selective coil embolization for SAAs, with 80% showing successful occlusion at the 3-month follow-up.
  • * DUS demonstrated a high sensitivity in detecting aneurysm closure but low specificity; despite its limitations, it may be a cost-effective and less invasive option for follow-up in certain low-risk patients.

Article Synopsis
  • * Recent studies indicate that autoimmunity, particularly autoantibodies, significantly contributes to the onset and persistence of AF by affecting heart rhythm regulation.
  • * Understanding the autoantibody profiles of different AF patient groups could lead to new treatment strategies, but the specific roles of these autoantibodies in AF are still under discussion.

Myocarditis is an inflammatory disease of the heart with a viral infection as the most common cause. It affects most commonly young adults. Although endomyocardial biopsy and cardiac magnetic resonance are used in the diagnosis, neither of them demonstrates all the required qualities.

(1) Background: Pulmonary embolism (PE) is the third most frequent acute cardiovascular condition worldwide. PE response teams (PERTs) have been created to facilitate treatment implementation in PE patients. Here, we report on the 5-year experience of PERT operating in Warsaw, Poland, with regard to the characteristics and outcomes of the consulted patients.

Micro-ribonucleic acids (microRNAs) are small molecules that take part in the regulation of gene expression. Their function has been extensively investigated in cardiovascular diseases (CVD). Most recently, miRNA expression levels have been suggested as potential biomarkers of platelet reactivity or response to antiplatelet therapy and tools for risk stratification for recurrence of ischemic evens.
