Spurious discharges due to late insulation break in an IS-1 pacing/sensing connector prompted ICD lead removal in 65-year-old man. The tip of the lead was easily freed and pulled back into the SVC by the superior approach. After that, the lead became trapped. The distal part of the lead was caught and easily withdrawn by inferior approach. Superior venous angiography showed extravascular location of the entrapped part of the lead due to the unintentional percutaneous puncture of the innominate vein after piercing the subclavian vein. It may be desirable to use contrast venography before intervention of extraction to ensure venous patency and lead location.

Transformers for Neuroimage Segmentation: Scoping Review.
J Med Internet Res
January 2025
Department of Computer Science and Software Engineering, United Arab Emirates University, Al Ain, United Arab Emirates.
Background: Neuroimaging segmentation is increasingly important for diagnosing and planning treatments for neurological diseases. Manual segmentation is time-consuming, apart from being prone to human error and variability. Transformers are a promising deep learning approach for automated medical image segmentation.

Biokinetic models can optimise pollutant degradation and enhance microbial growth processes, aiding to protect ecosystem protection. Traditional biokinetic approaches (such as Monod, Haldane, etc.) can be challenging, as they require detailed knowledge of the organism's metabolism and the ability to solve numerous kinetic differential equations based on the principles of micro, molecular biology and biochemistry (first engineering principles) which can lead to discrepancies between predicted and actual degradation rates.

End-of-life lithium-ion batteries (LIBs) present an opportunity to generate a circular economy through recycling. One of the techniques that can contribute to the purification of leached batteries is electrodialysis. In this work, we present a study of current variation in relation to monovalent (Li), divalent (Ni and Co) and trivalent (Al) cations from the synthetic solution of an NCA-type lithium-ion battery leachate, using electrodialysis membranes (HDX-100 and HDX-200) at three different current densities (12.

J Am Acad Orthop Surg
January 2025
From the Department of Orthopaedic Surgery, Johns Hopkins University, Baltimore, MD.
Background: Declining reimbursement rates can lead to decreased access and utilization of common orthopaedic surgeries for patients on Medicare, which is a particularly vulnerable population for musculoskeletal injuries.
Methods: Using the Centers for Medicare & Medicaid Services Physician Fee Schedule Look-Up Tool from 2016 to 2024 and utilization data for Medicare and part B beneficiaries from 2016 to 2022, we analyzed reimbursement and utilization trends. Simple linear regressions were executed to measure the annual trends, and Wilcoxon matched-pairs signed rank test were used to analyze the statistical significance of price and utilization changes.
Cellulose Nanofiber-Reinforced γ-AlOOH Aerogels for Enhanced Removal of Environmental Pollutants.

In this study, we report the modification of a monolithic γ-aluminum oxy-hydroxide (γ-AlOOH) aerogel with cellulose nanofibers (CNFs) using the sol-gel method via supercritical drying. The optimized 2% CNF (w/w) results in a monolithic CNF-γ-AlOOH that is amorphous in nature, along with C-C and C-O-C functional groups. Transmission electron microscopy (TEM) images of the as-synthesized CNF-γ-AlOOH showed CNF embedded in the γ-AlOOH aerogel.
