Catheter ablation and arrhythmia.

Nihon Naika Gakkai Zasshi, 1993
直流通電カテーテルアブレーションは,焼灼力は強いが,衝撃波発生等による重篤な合併症があり,普及しなかった.最近安全性の高い高周波通電法が開発され,薬物抵抗性の頻脈性不整脈に対し,広く臨床応用されるようになった.難治性の頻脈性心房細動,組動では主にHis束を焼灼して房室ブロックを作成し,ぺースメーカーを植え込む.房室結節回期頻拍に対しては,二重経路のうちのslow pathwayを選択的に焼灼し,房室ブロックの合併なく頻脈を完治させる. WPW症候群では,房室副伝導路を選択的に焼灼し,完全離断しうる.右室流出路起源等の特発性心室頻拍においても,その発生源を焼灼して完治させる.高周波通電法は安全性が高く,合併症はまれである.しかし深達度が浅いため,心筋梗塞や心筋症に伴う心室頻拍に対する有効性が低く ...

Highly multiplexed digital PCR assay for simultaneous quantification of variant allele frequencies and copy number alterations of KRAS and GNAS in pancreatic cancer precursors

Molecular Oncology, EarlyView.
Combining melting curve analysis enhances the multiplexing capability of digital PCR. Here, we developed a 14‐plex assay to simultaneously measure single nucleotide mutations and amplifications of KRAS and GNAS, which are common driver genes in pancreatic cancer precursors. This assay accurately quantified variant allele frequencies in clinical samples

Impact of undiagnosed obstructive sleep apnea on atrial fibrillation recurrence following catheter ablation (OSA-AF study)

International Journal of Cardiology: Heart & Vasculature, 2022
Background: Sleep-disordered breathing (SDB) may hamper the outcome of catheter ablation of atrial fibrillation (AF). However, SDB is underdiagnosed in clinical practice and the relevancy of undiagnosed SDB on the outcome of catheter ablation is unclear.

AAPM medical physics practice guideline 13.a: HDR brachytherapy, part B

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The goal of this report is to assist the clinical medical physicist in assuring that key quality standards and practice considerations are met to ensure safe, reliable, and reproducible high dose rate (HDR) brachytherapy (BT) treatment. This guideline has been developed to provide appropriate minimum standards for such services.
