Comparative Study
Comparison of Catheter Ablation in Patients with Paroxysmal Non-valvular Atrial Fibrillation and Heart Failure with Preserved Ejection Fraction.
Background: The efficacy of radiofrequency ablation (RFA) in patients with atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) has been established, but the efficacy and safety of cryoballoon ablation (CBA) and pulsed field ablation (PFA) remain unclear. Methods: This retrospective cohort study included 223 patients with paroxysmal non-valvular AF and HFpEF who underwent their first AF ablation between January 2017 and December 2021 and were divided into RFA (n = 77), CBA (n = 127), and PFA (n = 19) groups. Results: After a mean follow-up of 11.2 ± 1.8 months, no significant differences were observed in the rates of AF recurrence among the groups (P = 0.964). ⋯ RFA and PFA were associated with improved quality of life, improved NYHA functional classification, reversal of atrial remodeling, and increased LVEF. While CBA improved quality of life and NYHA functional status, it did not reverse atrial remodeling or increase LVEF. ALB and NT-pro BNP levels were identified as independent predictors of AF recurrence post-ablation in HFpEF patients.

Aminoglycosides and cisplatin drugs are extensively utilized for their high efficacy in treating various conditions in the clinic, however, their ototoxic side effects warrant significant attention. These drugs could penetrate the inner ear via specific channels or transporters, which not only affect the survival of hair cells but also induce the overproduction of reactive oxygen species. Currently, scientific research mainly addresses this issue through the downstream intervention of reactive oxygen species. ⋯ It is, therefore, imperative to investigate the regulatory role of the MET channel in the up-taking of ototoxic drugs, serving as a pivotal point for the development of preventative and therapeutic approaches. This review aims to highlight the mechanism of inhibition of ototoxic substances absorption by auditory hair cells, explore how to develop novel ear protection methods by targeting these channels and transporters, and provide a new perspective and strategy for addressing drug-induced ototoxicity. The approach to protecting hair cells by targeting these channels and transporters not only broadens our understanding of the underlying mechanisms of ototoxicity, but could also spur further research and progress in the field of auditory protection.

Background: A multitude of studies have presented inconsistent outcomes regarding the association between maternal folic acid (FA) and/or multivitamin (MV) supplementation and congenital heart disease (CHD) in offspring. This study aimed to estimate supplementation time and CHD based on a prospective China birth cohort study (CBCS). Methods: In the CBCS, 114,670 singleton pregnant women who had pregnancy outcomes until August 2021 and responded to the early pregnancy questionnaire were recruited. ⋯ The pooled RR from the forest plot was 0.98 (95% CI: 0.95-1.01), which is consistent with the findings of this study. Furthermore, the results remained approximately the same in the stratification or sensitivity analyses in different datasets, including performing 1:1 or 1:2 propensity score matching. Conclusions: The present study suggests that FA or MV supplementation before or during early pregnancy may not influence the risk of offspring developing CHD.

Background: Antiepileptics and antidepressants are frequently prescribed for chronic pain, but their efficacy and potential adverse effects raise concerns, including dependency issues. Increased prescriptions, sometimes fraudulent, prompted reclassification of antiepileptics in some countries. Our aim is to comprehend opinions, perceptions, beliefs, and attitudes towards co-analgesics from online discussions on X (formerly known as Twitter), offering insights closer to reality than conventional surveys. ⋯ Non-medical content included challenges in dispensing (25%), complaints about high costs (15%), and trivialization of medication use (10%). Conclusions: This study offers valuable insights into public perceptions of co-analgesics. Findings aid in designing public health communications to raise awareness of associated risks, urging both healthcare providers and the public to optimize drug use.

Background: Sinonasal inverted papilloma (SNIP) is characterized by a high recurrence rate and potential for malignant transformation. Although metabolic reprogramming plays a role in benign neoplasms, the specific metabolic pathways and biomarkers involved in SNIP pathogenesis remain unclear. Methods: RNA sequencing on paired SNIP and normal tissues identified altered genes with enzyme annotations and metabolic pathways by intersecting our cohort data (GSE270193, N=2) with the GSE193016 (N=4) dataset using Ingenuity Pathway Analysis. ⋯ Validation in an independent cohort confirmed elevated protein levels of these markers, all positively correlated with EGFR in SNIP tissues. Notably, AKR1B10, CYP2C19, and CYP3A5 exhibited specific expression patterns distinguishing SNIP from sinonasal squamous cell carcinoma. Conclusion: Altered estrogen biosynthesis signaling plays a role in SNIP pathogenesis, revealing distinct biomarkers that could serve as novel diagnostic markers and therapeutic targets for SNIP management.
