Ciertos cambios en el estilo de vida podrían reducir mucho el riesgo de accidente cerebrovascular (ACV), según un estudio reciente. Los investigadores calcularon el riesgo de ACV entre casi 23,000 estadounidenses negros y blancos a partir de los 45 años de edad.
Dfine, the developer of minimally invasive radiofrequency targeted therapies for the treatment of vertebral pathologies, released study results highlighting the clinical benefits of advanced Targeted-Radiofrequency Ablation(t-RFA) therapy for the management of patients experiencing painful spinal lesions. Eighty-five per cent of patients with metastatic disease will develop spinal metastases—of these nearly 75% will involve the axial skeleton.
En un estudio sobre militares de Estados Unidos en el exterior, aquellos con múltiples traumatismos de cráneo eran más propensos a tener pensamientos suicidas que los que habían sufrido una o ninguna de esas lesiones. "El personal militar con más de un traumatismo de cráneo en su vida era significativamente más propenso a haber intentado suicidarse en el pasado y en el último año", comentó el autor principal, Craig Bryan, del Centro Nacional para los Estudios sobre los Veteranos de University of Utah, Salt Lake City.
Durante las dos próximas décadas, se espera que el costo de tratar los accidentes cerebrovasculares (ACV) en EE. UU. se duplique y más, superando los 180 mil millones de dólares al año, según una investigación reciente. El principal factor subyacente del aumento es el envejecimiento de la población. El informe, de la Asociación Americana del Corazón (American Heart Association, AHA) y la Asociación Americana del Accidente Cerebrovascular (American Stroke Association), aparece en la edición del 22 de mayo de la revista Stroke.
Sequent Medical, Inc. (Aliso Viejo, CA) announced that it has received CE Mark approval for the SL (single-layer) family of Web aneurysm embolization devices and has commenced a controlled release of these new models in select neurovascular centers in Europe. The SL family offers a lower profile and excellent navigability that will enable physicians to treat a broader range of aneurysms with the Web platform, the company stated.

The Society for Cardiovascular Angiography and Interventions (SCAI) announced the presentation of a CREST (Carotid Revascularization Endarterectomy versus Stenting Trial) substudy at the SCAI 2013 scientific sessions in Orlando, Florida. The objective of this substudy was to evaluate whether undergoing angioplasty after carotid stenting increases the risk of complications such as stroke.
Un estudio de gran tamaño mostró que las personas mayores que seguían la dieta tenían una mejor retención de las habilidades mentales
Physicians at Ronald Reagan UCLA Medical Center are the first on the West Coast to perform a new, less-invasive procedure that is part of a clinical trial to help clear plaque from the carotid arteries, according to a release. The procedure took place on 28 March.
National Institutes of Health researchers used the popular anti-wrinkle agent Botox to discover a new and important role for a group of molecules that nerve cells use to quickly send messages. This novel role for the molecules, called SNARES, may be a missing piece that scientists have been searching for to fully understand how brain cells communicate under normal and disease conditions.
For the first time, a small device implanted in the brain has accurately predicted the onset of seizures in some adults who have epilepsy that does not respond to drugs, according to a small proof-of-concept study published online first in The Lancet Neurology.
May 3, 2013—Using a large, multihospital database, investigators sought to evaluate the morbidity and mortality associated with the use of intra-arterial or intravenous thrombolytic agents or glycoprotein IIb/IIIa inhibitors (GPI) to treat acute intraprocedural thrombus formation during endovascular cerebral aneurysm treatment. Waleed Brinjikji, MD, et al recently published the findings online ahead of print in Stroke.
Los investigadores afirman que un estrés mental más elevado y unos ingresos más bajos podrían tener algo que ver
May 1, 2013—The American Association of Neurological Surgeons (AANS) announced results from a recent study conducted by investigators from Boston Children’s Hospital that showed that the urinary levels of hepatocyte growth factor (HGF) could serve as a biomarker capable of detecting the presence of arteriovenous malformations (AVMs). Edward Robert Smith, MD, presented data from the study at the AANS annual scientific meeting, which was held April 27 to May 1 in New Orleans, Louisiana. The presentation was titled Noninvasive Urinary Biomarkers Can Detect the Presence of Intracranial Arteriovenous Malformations.
May 1, 2013—Findings from an analysis of stent-assisted coiling of intracranial aneurysms in 508 patients at a single center were published by Nohra Chalouhi, MD, et al in Stroke (2013;44:1348–1353).
