Clinical Outcomes of Catheter Ablation for Atrial Fibrillation in Patients with Acute Decompensated Heart Failure.

: The prognosis of acute decompensated heart failure (ADHF) and heart failure (HF) with atrial fibrillation (AF) has been dismal. This study was performed to investigate the clinical outcomes of catheter ablation (CA) performed in patients with concurrent ADHF and AF. : We retrospectively analyzed ADHF patients with AF who were admitted to our institution from 2007 to 2017.

Effect of Hardness Distribution on Strength of Narrow-Gap Hot-Wire Laser-Welded Joint for High-Tensile Strength Steel.

Application of high-heat input welding on high-tensile strength steels causes deterioration of mechanical properties of the welded joint, due to softening and grain coarsening in the heat-affected zone (HAZ). In this study, low-heat input narrow-gap hot-wire laser welding was applied to 12 mm thick 780 MPa-class high-tensile strength steel plate. Conditions were optimized based on microstructural observations of joints produced at various welding speeds.

Clinical Evaluation of a Rapid Reciprocal-Flow PCR Assay and Real-Time PCR Assay with Quenching Probe for Detection of Complex.

This study investigated the diagnostic efficiencies of two assays for the detection of complex: (1) the reciprocal-flow real-time polymerase chain reaction (PCR)-based GeneSoC assay and (2) the real-time PCR based GENECUBE MTB assay with quenching probe. These assays were performed for stored clinical samples and results were compared with the confirmed results based on culture and COBAS TaqMan MTB assay. A total of 53 samples (20 confirmed positives and 33 confirmed negatives) were included in the performance analysis.

Pharmacokinetic and Exposure-Response Modeling Support Body Surface Area-Based Dosing of Farletuzumab Ecteribulin in Japanese Patients with Solid Tumors.

The first-in-human, Phase 1 Study 101 showed antitumor activity and a tolerable safety profile of farletuzumab ecteribulin in Japanese patients with platinum-resistant ovarian and non-small cell lung cancer. A pharmacometric assessment evaluated farletuzumab ecteribulin pharmacokinetics and exposure-response (E-R) relationships for efficacy and safety to support dose optimization. Patients received 0.

Influence of Hospital Bed Count on the Positioning of Cardiovascular Interventional Radiology (IR) Nurses: Online Questionnaire Survey of Japanese IR-Specialized Radiological Technologists.

Background/objectives: Interventional radiology (IR) utilizing X-rays can lead to occupational radiation exposure, posing health risks for medical personnel in the field. We previously conducted a survey on the occupational radiation exposure of IR nurses in three designated emergency hospitals in Japan. Our findings indicated that a hospital with 214 beds showed a higher lens-equivalent dose than hospitals with 678 and 1182 beds because the distance between the X-ray irradiation field and the IR nurse's position of the hospital with 214 beds was shorter than those of 678 and 1182 beds.
