This letter to the editor concerns the article: 'Innovative tools for atrial fibrillation ablation' by Rottner et al., published in the journal on 13th of May 2020. We read the article with great interest and congratulate the authors on an impressively detailed summary of the current tools and technological advances in atrial fibrillation ablation. Improving the safety of this procedure is very important due to widespread clinical practice and the increasing demand for this procedure. We would like to share further discussion with the authors and the journal's readership on current advances in improving the safety of this procedure - esophageal cooling. The results of a large randomized trial was recently presented, the IMPACT study (NCT03819946), which showed that a simple, standardized method of esophageal cooling with the ensoETM® device can significantly reduce esophageal thermal injury by 83.4%. Esophageal protection is important as esophageal injury has a high mortality rate to those that sustain this injury although the overall incidence is low. Rottner et al. discuss a much smaller study on esophageal cooling and the limitations of this study are also discussed.

Proactive esophageal cooling during radiofrequency cardiac ablation: data update including applications in very high-power short duration ablation.
Expert Rev Med Devices
January 2025
Cardiac Electrophysiology, NorthShore University Health System, Evanston, IL, USA.
Introduction: Proactive esophageal cooling reduces injury during radiofrequency (RF) ablation of the left atrium (LA) for the treatment of atrial fibrillation (AF). New catheters are capable of higher wattage settings up to 90 W (very high-power short duration, vHPSD) for 4 s. Varying power and duration, however, does not eliminate the risk of thermal injury.

Introduction: Hypothermia can increase mortality in certain patients. Paramedics apply cotton and foil "space" blankets for warming, yet their effectiveness remains uncertain. This pilot study aimed to evaluate combining cotton blankets with a self-warming blanket versus a combination of cotton blankets and a foil blanket in an out-of-hospital simulation.

Article Synopsis
- Primary atopic disorders (PAD) are rare genetic conditions caused by specific gene variants that affect skin and immune function, making diagnosis challenging among common allergic disease cases.
- Identifying PAD requires recognizing clinical red flags like family history and unusual infections, as conventional lab tests are inadequate for definitive diagnosis.
- Whole-genome sequencing (WGS) enhances diagnostic efficiency and accuracy, but requires careful interpretation and collaboration among specialists to effectively manage PAD cases.
Inhibiting the expression of spindle appendix cooled coil protein 1 can suppress tumor cell growth and metastasis and is associated with cancer immune cells in esophageal squamous cell carcinoma.

Inhibiting the expression of spindle appendix cooled coil protein 1 (SPDL1) can slow down disease progression and is related to poor prognosis in patients with esophageal cancer. However, the specific roles and molecular mechanisms of SPDL1 in esophageal squamous cell carcinoma (ESCC) have not been explored yet. The current study aimed to investigate the expression levels of SPDL1 in ESCC via transcriptome analysis using data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases.

Background: Brain injury is one of the most serious complications after cardiac arrest (CA). To prevent this phenomenon, rapid cooling with total liquid ventilation (TLV) has been proposed in small animal models of CA (rabbits and piglets). Here, we aimed to determine whether hypothermic TLV can also offer neuroprotection and mitigate cerebral inflammatory response in large animals.
