A Systematic Review of modern endovascular techniques compared to surgery for acute limb ischaemia.

Introduction: Acute limb ischemia (ALI) represents a critical vascular emergency, conventionally managed with surgical intervention in cases of threatened limbs. However, the increasing application of modern endovascular techniques, such as percutaneous thrombectomy, has emerged as an alternative treatment approach for ALI. This systematic review evaluates the contemporary management of ALI.

Outcomes of Conservatively Managed Patients With Abdominal Aortic Aneurysm: A Single-Centre Experience.

Introduction: The results of patients at one hospital who were judged eligible for conservative care of abdominal aortic aneurysms (AAA) are examined in this research. Optimizing patient care and management tactics requires an understanding of the mortality trends and causes of death within this group.

Methodology: Sunderland Royal Hospital carried out a single-center retrospective analysis between May 2018 and January 2024.

Unveiling the impact of pipe materials on water hammer in pressure pipelines: an experimental and numerical study.

Water hammer (WH) is a phenomenon characterized by the rapid opening or closing of valves or pumps in pipelines, resulting in a disruptive noise, intense vibrations, and potential damage to pipes, fittings, structures, and even human safety. While WH arresters are commonly employed to mitigate this issue in smaller plumbing systems, alternative solutions are required for larger applications like power plants. Researchers have proposed the utilization of pipe materials with a low modulus of elasticity in areas prone to WH events, as these materials possess the capability to absorb a significant portion of the resulting vibrations.

Impact of Age Differences in Chronic Limb-Threatening Ischemia Outcomes in Octogenarians.

Background: The aging population is a growing challenge for healthcare services and as such multimorbidity and associated aging are the focus of research programs. Chronic limb-threatening ischemia (CLTI) in the older patient is perceived to be associated with high morbidity and mortality but a potentially contentious area with limited evidence.

Methods: Retrospective review of all consecutive CLTI admissions to a UK tertiary vascular during 2020.

Comparative study on free vibration analysis of rotating bi-directional functionally graded beams using multiple beam theories with uncertainty considerations.

The present study investigates the free vibration behavior of rotating beams made of functionally graded materials (FGMs) with a tapered geometry. The material properties of the beams are characterized by an exponential distribution model. The stiffness and mass matrices of the beams are derived using the principle of virtual energy.
