Physician-Modified Thoracic Stent Grafts for the Arch After Surgical Treatment of Type A Dissection

ConclusionsThe use of physician-modified thoracic stent grafts for the treatment of dissecting aortic arch aneurysm after surgical treatment of acute type A dissection is feasible and effective. Durability concerns will need to be assessed in future studies.Visual Abstract

This study investigated the relationship between homocysteine and multivascular atherosclerosis in stroke-related vascular beds using magnetic resonance imaging.MethodsPatients with recent ischemic cerebrovascular symptoms were enrolled and underwent three-dimensional magnetic resonance vessel wall imaging for intracranial arteries, extracranial carotid arteries and aortic arch. Traditional risk factors and homocysteine were measured. Presence of multivascular plaques defined as plaques in at least two stroke-related vascular beds on magnetic resonance imaging was determined. The relationship between homocysteine and chara...

Publication date: December 2019Source: Results in Physics, Volume 15Author(s): Cleverson FilgueirasAbstractIn this letter, we analyze a conceptual design for the operation of an Otto cycle heat machine driven by adiabatic modifications on the electronic effective mass. Such tailoring of it can be implemented, for instance, via the application of external electron fields in some materials, as in Gallium Nitride (GaN). We show that due both the energy quantization on this structure and the adiabatic transformation of the effective mass, the machine performance can be improved. The realization of classically inconceivable Ott...

Large trial held in Iran of inexpensive medication combining four common drugsA cheap, single pill taken once a day that combines four common drugs is safe and reduces the risk of events such as heart attacks, strokes and sudden death in people over the age of 50, research has found.The study, the first large-scale trial to date, looked at the effectiveness of a so-called polypill – a four-in-one therapy containing drugs to lower cholesterol and blood pressure that was first proposed more than 15 years ago. The researchers found those taking the polypill had a more than 30% lower risk of serious heart problems than t...

Cervical spondylosis may lead to spinal cord compression, poor vascular perfusion, and ultimately cervical myelopathy. The process whereby chronic compression may cause spinal cord damage has not been fully understood. However, multiple mechanisms such as inflammation, apoptosis, and vascular variations, are thought to be responsible for the neuronal loss, axonal degeneration, and myelin impairment seen in cervical spondylotic myelopathy (CSM). Studies reported a beneficial effect of renin-angiotensin system (RAS) blockers in the central nervous system, particularly in brain inflammation and stroke, but data on their influ...

Antifibrinolytic agents are used during ASD surgery to minimize blood loss and transfusion requirements. Tranexamic acid (TXA) reduces the risk of blood loss and transfusion after ASD surgery, but there persists concern for prothrombotic effects, myocardial infarction, stroke, and postoperative neurologic events including seizures.

Bariatric surgery for morbid obesity helps to address common comorbidity burdens, including decreasing rates of myocardial infarction and stroke. The increased mechanical stresses on the spine caused by morbid obesity predispose patients to various spinal pathologies and are concerning for spinal surgeons, with previous studies suggesting poorer outcomes than the general population. The effects of bariatric surgery on diminishing spinal complaints or symptoms have yet to be elucidated in the literature.
