Impact of Small Tumor Size on Prognosis in T3N1 Colon Cancer.

Background: Traditionally, large tumor size is associated with poor survival in colon cancer, but its impact remains limited and controversial. Recently, the impact of small tumor size on prognosis has gained attention. This study aimed to investigate whether small tumor size can be an additional parameter for T3N1 colon cancer prognosis.

Ultrasound-assisted middle thoracic epidural catheter placement utilizing the most dorsal sites of bilateral transverse process roots as anatomical landmarks: A cadaveric observational study and a clinical randomized controlled trial.

Study Objective: We developed an innovative method for ultrasound-assisted thoracic epidural catheter placement and assessed its potential to reduce procedural duration for trainees.

Design: A cadaveric observational study and a clinical randomized controlled trial.

Setting: Sapporo Medical University Hospital.

Relationship Between F-FDG-PET/CT-derived Tumor Glucose Metabolic Activity, Nutritional Risk, and Survival in Patients With Soft-tissue Sarcoma.

Background/aim: The present study aimed to assess the relationship between the maximum standardized uptake value (SUVmax) on F-fluorodeoxyglucose positron emission tomography computed tomography (F-FDG-PET/CT) and the geriatric nutritional risk index (GNRI) in patients with soft-tissue sarcomas (STSs).

Patients And Methods: The present single-center retrospective observational study included patients who underwent F-FDG-PET/CT and for whom serum albumin levels, height, and body weight were measured prior to therapeutic intervention.

Results: A total of 81 patients were included in the study.

Safety of Calcium Channel Blockers in Patients With Severe Aortic Stenosis and Hypertension.

Background: There is a paucity of data on safety of calcium channel blockers (CCB) in patients with severe aortic stenosis (AS) and hypertension.

Methods And Results: Among 2,460 patients with severe AS and hypertension receiving antihypertensive therapy in the CURRENT AS registry-2, we compared the clinical outcomes between patients taking antihypertensive therapy with CCB (CCB group) and without CCB (no CCB group). In the entire study population, CCB was prescribed in 1,763 patients (71.

Degradation and/or Dissociation of Neurodegenerative Disease-Related Factor Amyloid-β by a Suspension Containing Calcium Hydrogen Carbonate Mesoscopic Crystals.

Amyloid-β (Aβ) aggregates accumulate in the brains of individuals with Alzheimer's disease and are thought to potentially act as prions, promoting further aggregation. Consequently, the biochemistry of Aβ has emerged as a promising target for Alzheimer's disease. CAC-717, a suspension of calcium bicarbonate mesoscopic structures derived from natural sources, has been shown to inactivate various pathogens, including prions.
