Introduction: Recalibration of body ownership perception occurs through an integration among multiple modalities. A recent study has shown that respiratory rhythm also causes the recalibration of ownership perception. However, the risk factors influencing the recalibration of ownership perception caused by vision-respiratory interaction remain unclear.

Article Synopsis
  • This study investigates the safety and long-term outcomes of primary percutaneous coronary intervention (pPCI) for STEMI performed by less experienced operators under the guidance of experienced operators.
  • A total of 775 STEMI patients were divided into two groups based on operator experience, with outcomes suggesting that less experienced operators, when supported by seasoned professionals, had similar rates of cardiovascular events compared to experienced operators.
  • The results showed no significant increase in risk for in-hospital mortality or 5-year cardiovascular events for patients treated by less experienced operators, indicating that proper support can ensure safety in pPCI procedures.

Transposable elements (TEs) are mobile parasitic sequences that have expanded within the host genome. It has been hypothesized that host organisms have expanded the Krüppel-associated box-containing zinc finger proteins (KRAB-ZFPs), which epigenetically suppress TEs, to counteract disorderly TE transpositions. This process is referred to as the evolutionary arms race.

Aim: Early and intensive low-density lipoprotein (LDL-C)-lowering therapy plays important roles in secondary prevention of acute coronary syndrome (ACS), but the treatment period for further clinical benefit remains undefined. This single-center, retrospective study explored LDL-C trajectory after ACS and its associations with subsequent cardiovascular events (CVE).

Methods: In 831 patients with ACS, we evaluated LDL-C reduction during the first 2 months post-ACS as an index of early intervention and the area over the curve for LDL-C using 70 mg/dl as the threshold in the next 6 months (AOC-70) as a persistent intensity index.

Article Synopsis
  • The CALLY index is a new biomarker that uses levels of C-reactive protein, serum albumin, and lymphocyte count to predict outcomes in colorectal cancer patients.
  • In a study of 578 stage II-III colorectal cancer patients who had surgery, a CALLY index score below 2 was linked to worse disease-free survival (DFS) and overall survival (OS).
  • The findings suggest that the CALLY index could serve as an independent predictor of long-term outcomes for colorectal cancer patients undergoing curative surgery.

Background: Mechanical compression of cardiac conduction system by transcatheter heart valves leads to complete atrioventricular block (CAVB) after transcatheter aortic valve replacement (TAVR). Bulging of ventricular septum in the left ventricular outflow tract (LVOT) may be associated with greater compression of conduction system, leading to irreversible CAVB.

Objective: This study aimed to investigate the association of ventricular septal bulging with TAVR-related CAVB and permanent pacemaker implantation (PPI).
