Background: In patients undergoing transvenous lead extraction (TLE), lead dwell time has been recognized as a risk factor for extraction failure and procedure-related complications.
Objectives: The aim of this study was to evaluate the safety and effectiveness of TLE in patients with pacemaker or ICD leads with a dwell time of ≥20 years.
Methods: This is a single-center retrospective study of all patients who underwent TLE of at least 1 pacemaker or ICD leads a dwell time of ≥20 years.
Results: During the study period, 124 patients were included in this analysis (50.8% female, mean age: 74.6 ± 10.7 years). Device-related infection was the most common (92.7%) indication for TLE. Extraction was attempted for a total 313 leads, of which 182 leads had dwell times ≥20 years (median: 276 months; interquartile range: 255-300 months). Complete procedural success was achieved in 112/124 patients (90.3%), and clinical success in 119/124 patients (96.0%). Complete removal was achieved for 294 leads (93.9%), partial removal in 10 leads, and failure in 9 leads. Clinical success (combined complete and partial success) rates were higher for leads with dwell times <20 years compared to older leads (99.2% vs. 95.6%, p = .017). Major procedural complications (including 1 death) occurred in 7/124 patients (5.6%). Minor complications were observed in 8 patients (6.5%).
Conclusions: TLE of very old (≥20 years) leads can be performed with reasonable success and safety when conducted at centers with expertise in lead management.

Background: Lumen-apposing metal stents (LAMS) are utilized in a wide range of therapeutic gastrointestinal applications. We present our experience with LAMS-assisted drainage of complex pelvic abscesses at a large safety-net hospital.
Methods: EUS-guided LAMS placements for pelvic abscesses from July 2020 to June 2024 were analyzed.

In Saccharomyces cerevisiae, SKS1 mRNA encoding a glucose-sensing serine/threonine kinase belongs to "nucleus-retained" (NR) mRNAs representing a subset of otherwise normal transcripts, which exhibits slow nuclear export and excessively long nuclear dwell time. Nuclear retention of the SKS1 mRNA triggered by a 202 nt "export-retarding" nuclear zip code (NZ) element promotes its rapid degradation in the nucleus by the nuclear exosome/CTEXT. In this investigation, we demonstrate that Dbp2p, an ATP-dependent DEAD-box RNA helicase binds to SKS1 and other NR-mRNAs and thereby inhibits their export by antagonizing with the binding of the export factors Mex67p/Yra1p.

The extravascular implantable cardioverter-defibrillator (EV-ICD) was developed to overcome complications associated with transvenous leads while being able to deliver anti-tachycardia pacing (ATP). The lead is implanted in the substernal space, which makes extraction a cautious procedure. We present a case of a 51-year-old women with a successful EV-ICD extraction after a lead dwell time of 4 years, which is the longest reported.

Background: Catheter-related bloodstream infection (CR-BSI) stands as one of the leading causes of hospital-acquired infections, often resulting in high healthcare expenditure and mortality rates. Despite efforts, reducing the incidence of CR-BSI remains a significant challenge.
Objective: This study aimed to assess the impact of a multidisciplinary organizational intervention on reducing intravenous CR-BSI.
