Post-traumatic stress disorder (PTSD) is a psychiatric disorder that develops and persists after an individual experiences a major traumatic or life-threatening event. While pharmacological treatment and psychological interventions can alleviate some symptoms, pharmacotherapy is time-consuming with low patient compliance, and psychological interventions are costly. Repetitive Transcranial Magnetic Stimulation (rTMS) is a safe and effective technique for treating PTSD, with advantages such as high compliance, low cost, and simplicity of implementation.

Article Synopsis
  • The study focuses on enhancing the prediction of esophageal variceal bleeding (EVB) in cirrhosis patients through a radiomics approach that uses multi-organ data rather than relying on a single imaging level.
  • Researchers evaluated 208 cirrhosis patients, dividing them into training and validation groups, and extracted radiomic features from key organs: liver, spleen, and lower esophagus-gastric fundus.
  • The resulting radiomics-clinical model (RC model) showed superior predictive ability for EVB risk, identifying ascites, portal vein thrombosis, and plasma prothrombin time as significant clinical risk factors, achieving high area under the curve (AUC) values in the training cohort.*

With continuous advancements in interventional radiology, considerable progress has been made in transarterial therapies for hepatocellular carcinoma (HCC) in recent years, and an increasing number of research papers on transarterial therapies for HCC have been published. In this editorial, we comment on the article by Ma published in the recent issue of the "Efficacy and predictive factors of transarterial chemoembolization combined with lenvatinib plus programmed cell death protein-1 inhibition for unresectable HCC". We focus specifically on the current research status and future directions of transarterial therapies.

Article Synopsis
  • This study compared two types of surgery for prostate cancer: robotic-assisted radical prostatectomy (RARP) and three-dimensional laparoscopic radical prostatectomy (3D LRP) by reviewing many medical studies.
  • RARP led to much less blood loss during surgery, but both surgery types had similar results in terms of recovery time and other health checks afterward.
  • The overall conclusion is that RARP is better for blood loss, but both surgeries are mostly the same when looking at other important outcomes.

Article Synopsis
  • Esophageal cancer (ESCA) has a high rate of morbidity and mortality, especially in Asia, and the role of TERF2 in its development is not well understood, despite its importance in maintaining telomere stability.
  • The study assessed TERF2 expression in esophageal squamous cell carcinoma (ESCC) samples using various techniques, revealing that elevated TERF2 levels correlate with patient's age, sex, cancer stage, and other clinical factors.
  • Findings suggest TERF2 is an independent prognostic factor for overall survival in ESCC patients and may play a key role in cell proliferation through the DDR/TP53 signaling pathway, indicating its potential as a target for future treatments and diagnostics in ESCA.

Osimertinib, a third-generation inhibitor of epidermal growth factor receptor (EGFR) tyrosine kinase, exhibits remarkable efficacy in prolonging the survival of patients with non-small cell lung cancer (NSCLC) carrying mutations, surpassing the efficacy of first- and second-generation EGFR tyrosine kinases. Nevertheless, the emergence of osimertinib resistance is inevitable, necessitating an investigation into the underlying mechanisms. Increasing evidence has revealed that non-coding RNAs (ncRNAs), including microRNAs, long ncRNAs, and circular RNAs, play a significant role in the development and progression of lung cancer.
