Background: Lumenless leads (LLLs) are widely used for left bundle branch area pacing (LBBAP). Recently, stylet-driven leads (SDLs) have also been used for LBBAP.
Objective: The purpose of this study was to evaluate the acute performance of SDLs during LBBAP in comparison with LLLs.
Methods: Consecutive patients undergoing LBBAP for bradycardia or cardiac resynchronization therapy indications at 2 high-volume, early conduction system pacing adopters, tertiary centers were included from January 2019 to July 2023. Patients received either SDLs or LLLs at the discretion of the implanting physician. Acute performance and follow-up data of both lead types were evaluated.
Results: A total of 925 LBBAP implants were included, 655 using LLLs and 270 using SDLs. Overall, LBBAP acute success was significantly higher with LLLs than SDLs (95.3% vs 85.1%, respectively; <.001) even after the learning curve (97% vs 86%; = .013). LLLs were implanted in more mid-basal septal positions in comparison with SDLs, which tended to be implanted in more inferior and mid-apical septal positions. Acute lead-related complications were higher with SDLs than LLLs (15.9% vs 6.1%, respectively; <.001) with 15 cases of lead damage during implant (4.4% vs 0.5%; <.001) but decreased with acquired experience and were comparable in the last 100 patients included in each group. Lead implant and fluoroscopy times were shorter for SDLs, with lead dislodgment occurring in 0.9% with LLLs and 1.5% with SDLs ( = .489).
Conclusion: Acute lead performance proved to be different between LLLs and SDLs. A specific learning curve should be considered for SDLs even for implanters with extensive previous experience with LLLs.

Association of radiation-induced normal tissue toxicity with a high genetic risk for rheumatoid arthritis.
J Natl Cancer Inst
January 2025
Translational Radiobiology Group, Division of Cancer Sciences, University of Manchester, The Christie NHS Foundation Trust, Manchester, United Kingdom.
Purpose: Overlapping genes are involved with rheumatoid arthritis (RA) and DNA repair pathways. Therefore, we hypothesised that patients with a high polygenic risk score (PRS) for RA will have an increased risk of radiotherapy (RT) toxicity given the involvement of DNA repair.
Methods: Primary analysis was performed on 1494 prostate cancer, 483 lung cancer and 1820 breast cancer patients assessed for development of RT toxicity in the REQUITE study.
Indications for continuous electroencephalography and frequency of electrographic seizure detection in a pediatric and neonatal cardiovascular intensive care unit.
Epilepsia
January 2025
Division of Child Neurology, Stanford Medicine Children's Health, California, USA.
Objective: Seizures are a recognized complication of critical cardiovascular illness in infants and children. We assessed the diagnostic yield of continuous video-electroencephalography (cEEG) in a pediatric and neonatal cardiovascular intensive care unit (CVICU) by the symptoms and risk factors prompting cEEG evaluation.
Methods: This retrospective case series included all consecutive cEEGs in patients ≤21 years old performed in one CVICU over 38 months.
Incarceration is associated with higher mortality after trauma: An unreported health care disparity.

Background: While the United States has the highest incarceration rate worldwide, at nearly 1% of the adult population (more than 2 million people), insights regarding health disparities in this population remain limited. This retrospective cohort study represents the largest national database analysis of incarcerated trauma patients to date and investigates whether incarceration status is an independent risk factor for poor outcomes after trauma for US adults.
Methods: We analyzed data from the National Trauma Data Bank from 2017 to 2018.

This study tested whether combined ceftriaxone and adipose-derived mesenchymal stem cells (ADMSCs) would defend the spinal cord against acute spinal infection (ASI) in rodent. Adult-Male-SD rats were grouped into groups 1 (SC)/2 (ASI)/3 (ASI + ceftriaxone from days 2 to 28 after ASI induction)/4 (ASI + allogenic ADMSCs from day 2 for a total of 3 doses/3 consecutive intervals by intravenous injection)/5 (ASI + combined ceftriaxone and ADMSC) and spinal cord tissues were harvested by day 28. Circulatory levels of TNF-α/IL-6 at days 7 and 28, and these two parameters in spinal fluid at day 28 were lowest in group 1, highest in group 2, significantly lower in group 5 than in groups 3/4, and significantly lower in group 3 than in group 4 (all p < 0.

Unlabelled: This study aimed to evaluate pathological findings on abdominal ultrasonography upon admission of children diagnosed with Multisystem Inflammatory Syndrome in Children (MIS-C) that were associated with a more severe disease course and the need for intensive care unit (ICU) admission. This retrospective and observational study was conducted between March 2020 and May 2022. Abdominal ultrasonography findings were evaluated in children diagnosed with MIS-C associated with SARS-CoV-2.
