Article Abstract

Triple arterial access is sometimes necessary for complete visualization of the collateral circulation and distal vessel anatomy, and to facilitate the retrograde approach in complex chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in patients with prior coronary artery bypass surgery (CABG) and multiple sources of collaterals. We present two CTO PCI cases in prior CABG patients with complex occlusions supplied by multiple sources of collaterals for which a "sequential dual guide technique" was used, reducing the number of necessary arterial access points from three to two.

Recent studies have shown that the glymphatic system plays a crucial role in driving hyperacute edema after ischemic stroke. This has sparked interest in understanding how this system changes in later phases of ischemic stroke. In this study, we utilized cisternal contrast-enhanced magnetic resonance imaging (CE-MRI) and immunofluorescence staining to investigate glymphatic system alterations at subacute and chronic phases of ischemic stroke.

What are the key targets to improve quality of life among MSM living with HIV on antiretroviral therapy? A network analysis.

Qual Life Res

September 2025

Department of Epidemiology, School of Public Health, Cheeloo College of Medicine, Shandong University, 44 West Wenhua Road, Jinan, 250012, Shandong, China.

Purpose: The study aimed to assess the interconnection of quality of life (QoL) variables and identify key areas for which interventions could improve QoL among men who have sex with men (MSM) living with HIV on antiretroviral therapy (ART).

Methods: A cross-sectional study was conducted in Jinan of Shandong Province, between October to December 2020. Undirected network analyses were conducted to examine and visualize the interconnections between QoL variables among MSM living with HIV.

Aim And Background: This study investigates the impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in patients undergoing radical surgery for right-sided colon cancer. Given that postoperative diarrhea can significantly affect the quality of life, we examined whether dissection boundaries influence these outcomes.

Methods: This was a prospective, randomized controlled trial conducted at a high-volume tertiary hospital.

Introduction: Night Eating Syndrome (NES) is a distinct psychopathological entity variously considered as a mental health disorder, eating disorder or circadian rhythm disorder. Medical students are faced with hectic schedules, sleep interruptions and high-stakes exams as they become healthcare providers. Such social factors coupled with poor dietary practices may impact their mental health and biological clocks, leading to NES amongst this population.

Background: Limited treatment options exist for infrapopliteal disease in patients with chronic limb-threatening ischemia (CLTI), a condition associated with a high risk of limb loss. Interventional management of diseased infrapopliteal vessels with percutaneous transluminal angioplasty (PTA) is associated with high rates of restenosis and reintervention. In the LIFE-BTK trial, the drug-eluting resorbable scaffold (DRS) demonstrated superior 12-month efficacy compared with PTA in a selected CLTI population with predominantly noncomplex, mildly to moderately calcified lesions.
