Importance: Recurrence remains a challenge after ablation of outflow tract premature ventricular contractions (OT-PVCs). Although adding additional lesions next to the index effective ablation site is sometimes performed to reinforce the ablation, it remains uncertain whether this approach is effective.

Objective: To test the hypothesis that additional ablation lesions would reduce the recurrence rate compared with single-point ablation at the index effective site for the ablation of OT-PVCs.

Impact of Operator Experience on Left Atrial Appendage Occlusion Outcomes.

JACC Clin Electrophysiol

November 2024

Department of Cardiology, Xijing Hospital, The Fourth Military Medical University, Xi'an, China. Electronic address:

Article Synopsis
  • * It analyzed data from 1,547 patients and 111 operators who participated in the RECORD study in China, finding that performing at least 32 LAAOs per year significantly lowers risks compared to those with less experience.
  • * The results indicate that a less experienced group (performing <32 LAAOs annually) had a 1.8 times higher risk of adverse outcomes, but this risk decreased as operators completed more procedures.

Hypothermia is commonly used to protect donor hearts during transplantation. However, patients transplanted with aged donor hearts still have severe myocardial injury and decreased survival rates, but the underlying mechanism remains unknown. Because aged hearts are not considered suitable for donation, the number of patients awaiting heart transplants is increasing.

Our study identified a novel long noncoding RNA, LINC01322, that acts as an oncogene in lung adenocarcinoma progression. Cytoplasmic and nuclear RNA purification assays indicated that LINC01322 was localized in the cytoplasm and nucleus. Gene set enrichment analysis revealed the involvement of LINC01322 in the regulation of cell proliferation, migration, and the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway.

Sex-biased molecular differences in lung adenocarcinoma are ethnic and smoking specific.

BMC Pulm Med

March 2023

Center for Medical Research On Innovation and Translation, Institute of Clinical Medicine, Guangzhou First People's Hospital, School of Medicine, South China University of Technology, Guangzhou, 510180, Guangdong, China.

Article Synopsis
  • The study investigates how sex differences affect lung adenocarcinoma (LUAD) in terms of genetic mutations, gene expression, and immune system responses, focusing on various ancestries and smoking statuses.
  • It reveals that among nonsmokers, there are more male-biased mutations in Asian LUAD patients, while females show a higher mutation rate for EGFR across both Asian and Non-Asian populations.
  • Additionally, the research demonstrates that immune cell types and their responses to treatments differ by sex, with females exhibiting unique sensitivity to immunotherapy linked to specific gene expressions.

Introduction: Concurrent chemoradiotherapy (CCRT) is the standard of care for inoperable locally advanced non-small cell lung cancer. To further improve prognosis, the use of consolidation treatments after CCRT has been explored extensively. Although durvalumab is the only consolidation treatment recommended by national clinical practice guidelines, there have been many studies exploring the effectiveness of other agents.

Reactive Oxygen Species (ROS) are present in excess amounts in patients with tumors, and these ROS can kill and destroy tumor cells. Therefore, tumor cells upregulate ROS-related genes to protect them and reduce their destructing effects. Cancer cells already damaged by ROS can be repaired by expressing DNA repair genes consequently promoting their proliferation.
