The end-results of combined and surgical treatment of gastric cancer are compared. Survival rates were sufficiently high in both procedures in cases without extension through the serosa (T1-2) or regional metastases with adenocarcinoma cells were well differentiated (NO). However, combined treatment proved more effective in cases of the opposite situations (p=0.04-0.0001). Considering the possibility of inadequate staging, the following indications for preoperative radiotherapy are suggested: low cell differentiation, signet-cell or undifferentiated gastric tumor of 3-10 cm in diameter. In other words, early cancer of the stomach and total involvement must be excluded.

Objective: Early and accurate diagnosis of prostate cancer (PC) is crucial for effective treatment. Diagnosing clinically insignificant cancers can lead to overdiagnosis and overtreatment, highlighting the importance of accurately selecting patients for further evaluation based on improved risk prediction tools. Novel biomarkers offer promise for enhancing this diagnostic process.

Department of Clinical Research, University of Southern Denmark, 5000 Odense, Denmark.
Background: Peyronie's disease (PD) is a fibrotic disorder affecting the penile tunica albugínea, with unclear pathophysiology despite centuries of recognition.
Aim: This scoping review maps the effects of interventions in basic PD research, synthesizing evidence from in vivo and in vitro studies to guide future investigation.
Methods: In October-November 2023, a systematic search was conducted across PubMed, Embase (Ovid), Science of Web, and Scopus, following SRYCLE's guidelines.
Effect of Dexmedetomidine on the ED and ED of Sufentanil in Patient-Controlled Intravenous Analgesia After Cesarean Section: A Randomized, Controlled, Double-Blind Trial.

Department of Anesthesiology, Affiliated Hospital of North Sichuan Medical College, Nanchong, People's Republic of China.
Purpose: To determine the effect of dexmedetomidine on the ED and ED of sufentanil in patient-controlled intravenous analgesia (PCIA) after cesarean section.
Patients And Methods: Parturients who underwent elective cesarean section (n = 80) were randomly assigned to either the sufentanil group (S group) or the dexmedetomidine-sufentanil combination group (DS group). Patients in the S group received a combination of sufentanil, 5 mg of tropisetron, and saline, whereas patients in the DS group were administered 1.
Radical Resection of Differentiated Thyroid Cancer in Elderly Patients: Evaluation of the Efficacy of the Immunocolloidal Gold Strip Method Combined with Nanocarbon Negative Imaging Tracing Technology for Parathyroid Gland Imaging.

The First Affiliated Hospital of Hebei North University, Zhangjiakou, China.
Objective: Extant imaging methods used for the proper identification of the parathyroid glands to prevent post-operative hypothyroidism associated with the resection of differentiated thyroid cancer (DTC) are limited by factors such as low specificity, high cost, and technical complexity. This study, therefore, sought to investigate the efficacy of the immunocolloidal gold strip method combined with nanocarbon negative imaging tracing technology for parathyroid gland imaging during radical resection of DTC in elderly patients.
Methods: A total of 100 elderly patients with DTC were enrolled and randomly divided into two groups: the control group and the observation group.

To assess the efficacy and safety of "one-stop" procedures combining radiofrequency catheter ablation and left atrial appendage closure by guidance of intracardiac echocardiography(ICE) in elderly patients with atrial fibrillation. A retrospective cohort study was conducted on patients who underwent ICE-guided "one-stop" procedures at the Department of Cardiology, General Hospital of Northern Theater Command between December 2020 and January 2023. Patients were divided into elderly group (age≥60 years old) and non-elderly group (age 18-59 years old).
