The right heart catheterization (RHC) remains an important diagnostic tool for a spectrum of cardiovascular disease processes including pulmonary hypertension (PH), shock, valvular heart disease, and unexplained dyspnea. While it gained widespread utilization after its introduction, the role of the RHC has evolved to provide valuable information for the management of advanced therapies in heart failure (HF) and cardiogenic shock (CS) to name a few. In this review, we provide a comprehensive overview on the indications, utilization, complications, interpretation, and calculations associated with RHC.

Nuclear speckles are dynamic nuclear bodies characterized by high concentrations of factors involved in RNA production. Although the contents of speckles suggest multifaceted roles in gene regulation, their biological functions are unclear. Here we investigate speckle variation in human cancer, finding two main signatures.

Article Synopsis
  • Hepatocellular carcinoma (HCC) arises from liver cells (hepatocytes) that are damaged and undergoing compensatory growth, particularly due to metabolic disorders like MASH.
  • The tumor-suppressive effects of p53 and the anti-cancer role of the enzyme FBP1 are undermined in HCC, as FBP1 is commonly degraded and suppressed in tumors.
  • Key metabolic pathways involving AKT and NRF2 play a role in reversing the effects of cellular senescence, boosting the growth of HCC cells and leading to the accumulation of genetic mutations that contribute to cancer progression.

Aims: Utilization of transvenous lead extraction/removal (TLE) for the management of cardiac implantable electronic device (CIED)-associated infective endocarditis (IE) remains low. The aim of this study was to examine the impact of hospital TLE procedural volume on TLE utilization and outcomes for patients with CIED-associated IE.

Methods And Results: Using the Nationwide Readmissions Database, we evaluated 21 545 admissions for patients (mean age 70 years, 39% female) with CIEDs hospitalized with IE at TLE centres.

Background: Intracerebral schwannomas are rare tumors resembling their peripheral nerve sheath counterparts but localized in the CNS. They are not classified as a separate tumor type in the 2021 WHO classification. This study aimed to compile and characterize these rare neoplasms morphologically and molecularly.
