Introduction: Controversy exists regarding the indication of beta-blockers (BB) in different scenarios in patients with cardiovascular disease. We sought to evaluate the effect of BB on survival and heart failure (HF) hospitalizations in a sample of pacemaker-dependent patients after AV node ablation to control ventricular rate for atrial tachyarrhythmias.
Methods: A retrospective study including consecutive patients that underwent AV node ablation was conducted in a single center between 2011 and 2019. The study's primary endpoints were the incidence of all-cause mortality, first HF hospitalization and the cumulative incidence of subsequent hospitalizations for HF. Competing risk analyses were employed.
Results: A total of 111 patients with a mean age of 73.9 years were included in the study. After a median follow-up of 45.5 months, 43 patients had died (38.7%) and 31 had been hospitalized for HF (27.9%). The recurrent HF hospitalization rate was 74/1000 patients/year. Patients treated with BB had a non-significant trend to higher mortality rates and a higher risk of recurrent HF hospitalizations (incidence rate ratio 2.23, 95% confidence interval 1.12-4.44; p = 0.023).
Conclusion: After an AV node ablation, the use of BB is associated with an increased risk of HF hospitalizations in a cohort of elderly patients.

Introduction: The presence of wounds in addition to the excision-induced wounds after severance from the stock plants is known to positively influence adventitious root formation of woody plant cuttings. Previous morphological studies highlighted laser wounding as a technique allowing to precisely control the decisive ablation depth. However, the biochemical processes involved in the response of rooting to the additional wounding remained unexplored.

Background: The lymphatic system is the major route of cancer metastasis, and sentinel lymph nodes (SLNs) are the first station for the spread of cancer cells. Accurate identification of SLNs by tracers during surgery is crucial for SLN biopsy and lymphadenectomy. However, conventional monomodal tracers such as blue dyes and carbon nanoparticles often induce a misjudgment of SLNs and thus are still unsatisfying for clinical applications.

Background: Patients undergoing first-time atrial fibrillation (AF) ablation can benefit from targeting non-pulmonary vein (PV) triggers. Preprocedural identification of high-risk individuals can guide planning of ablation strategy. This study aimed to create a preprocedural screening tool to identify patients at risk of non-PV triggers during first-time AF ablation.

Background: We attempted to establish correlations between intraoperative variables such as time-to-isolation (TTI) and temperature (T) at the 30-second mark, and the sustained efficacy of pulmonary vein isolation.
Methods: One hundred patients underwent repeat procedures subsequent to their index ablation. Five time intervals were delineated based on TTI metrics of 30, 35, 40, 45, and 60 s during the initial procedure.

Triple-negative breast cancer (TNBC) has profound unmet medical need globally for its devastating clinical outcome associated with rapid metastasis and lack of targeted therapies. Recently, lipid metabolic reprogramming especially fatty acid oxidation (FAO) has emerged as a major driver of breast cancer metastasis. Analyzing the expression of major FAO regulatory genes in breast cancer, we found selective overexpression of acyl-CoA synthetase 4 (ACSL4) in TNBC, which is primarily attributed to the absence of progesterone receptor.
