An update to the American Heart Association and American Stroke Association guidelines for the management of aneurysmal subarachnoid hemorrhage places new emphasis on treating patients at high-volume centers with multidisciplinary teams and following up with patients after treatment to detect rebleeding and delayed cerebral ischemia, along with other potential complications.
Stroke is one of the new measures that hospitals must report on starting Jan. 1, 2013, to receive full Medicare reimbursement for stroke care delivered in 2015. The requirement is part of the Centers for Medicare and Medicaid Services (CMS) Hospital Inpatient Quality Reporting Program, which was established in 2003, with the goal of improving inpatient care.
People who habitually sleep less than 6 hours appear to be at risk of developing symptoms that may predict future stroke, researchers reported here at the annual meeting of the Associated Professional Sleep Societies. Study participants with normal body mass indices (BMIs) who slept less than 6 hours a night had a 4.5-fold increased risk of having a stroke-like symptom compared with similar individuals who got 8 to 9 hours of sleep a night (P=0.002), Megan Ruiter, PhD, a postdoctoral fellow at the University of Alabama at Birmingham, said in an oral presentation.
Individuals scoring higher on a measure of general mental health had an increased risk of stroke mortality, a population-based study showed. Psychological distress predicted a significant 66% elevated risk of death from cerebrovascular disease, Mark Hamer, PhD, of the University College London, and colleagues found.
Patients who were taking warfarin were no more likely to develop symptomatic intracranial hemorrhage after treatment with intravenous tissue plasminogen activator (tPA) than those not on the anticoagulant, a large observational study showed. Nor was there an increased risk of serious systemic hemorrhage, any tPA complications, or in-hospital mortality, according to Eric Peterson, MD, of the Duke Clinical Research Institute, and colleagues.
Stroke survivors had significantly better functional and cognitive outcomes when they received a nitric oxide-inducing hormone in addition to rehabilitation, Italian investigators reported. At 20 days, patients who received porcine-derived relaxin showed significantly better recovery of global and cognitive function (P=0.001 and P=0.002, respectively), but not daily activities, as compared with patients randomized to rehabilitation alone.
Both sexes gain from statins for secondary prevention of cardiovascular events, a meta-analysis found, though pooling enough data to prove that there is a statistically significant benefit in women appears to be a challenge. Both sexes saw a similar, significant overall cardiovascular benefit from the lipid-lowering drugs in high-quality clinical trials, Jose Gutierrez, MD, MPH, of Columbia University in New York City, and colleagues reported.
A simple risk prediction model that uses clinical and echocardiographic characteristics may help identify ischemic stroke patients at a higher risk of future adverse outcomes, researchers found. Age, chronic renal failure, and the amount of calcification around the aortic root were predictive of death at about 4 years after nonhemorrhagic stroke, Avinash Murthy, MD, from the Albany Medical Center in Albany, N.Y., and colleagues reported.
The Penumbra System® family of aspiration thrombectomy devices now includes the MAX System of Reperfusion Catheters for removal of clots in patients experiencing acute ischemic stroke. The MAX System neuro-interventional devices offer a fast, simplified cerebral thrombectomy procedure with single-operator, over-the-wire delivery without the need for a large proximal balloon guide.
Una de cada cinco personas a las que se les realiza una cirugía para eliminar una obstrucción arterial y prevenir un accidente cerebrovascular (ACV) es demasiado grande y está muy enferma como para obtener algún beneficio. "Esto no me sorprende demasiado porque percibía que no estábamos seleccionando adecuadamente a los pacientes", dijo la doctora Jessica Wallaert, autora principal del estudio e investigadora del Centro Médico Dartmouth-Hitchcock, en Nueva Hampshire.
Las personas con niveles de glucemia más altos de lo normal (o prediabetes) podrían estar en mayor riesgo de sufrir de un accidente cerebrovascular (ACV) más adelante, según una revisión reciente. Investigadores de la Universidad de California advirtieron que esto podría representar un problema de salud a gran escala, ya que la prediabetes afecta a más de 79 millones de personas tan solo en Estados Unidos.
A menos que esté en riesgo alto de enfermedad cardiovascular, probablemente no deba tomar una aspirina de dosis baja todos los días, sugiere un estudio reciente. Investigadores informan que el uso de aspirina diaria a dosis baja podría aumentar significativamente la probabilidad de un sangrado gastrointestinal o cerebral mayor. Cualquier beneficio de la aspirina de dosis baja en la prevención de la enfermedad cardiaca podría ser anulado por ese riesgo, señalaron los autores del estudio
Las personas que sufren de ansiedad, depresión, insomnio y otras formas de distrés psicológico están en mayor riesgo de muerte por accidente cerebrovascular (ACV), según un estudio reciente. Investigadores del Colegio Universitario de Londres apuntaron que el distrés psicológico afecta a entre 15 y 20 por ciento de la población general. Investigaciones anteriores han relacionado a estas afecciones mentales comunes con la enfermedad de la arteria coronaria, pero no se ha establecido una asociación con el ACV y otras enfermedades cardiovasculares.
IsoRay Inc. (ISR), a medical technology company and innovator in seed brachytherapy and medical radioisotope applications, today announced another milestone in the treatment of brain tumors using its groundbreaking Cesium-131 (Cs-131) seed sutured mesh for internal radiation therapy. Dr. Kris Alan Smith, surgeon and Medical Director, Gamma Knife Center, supported by Dr. David G. Brachman, Medical Director of Radiation Oncology at St. Joseph s Hospital & Medical Center, Barrow Neurological Institute in Phoenix, Arizona, performed the world s first Cesium-131 brachytherapy seed sutured mesh implant on a female patient suffering from a recurring meningioma tumor.
A randomised controlled trial published in The Lancet Neurology in May has shown that for patients with suspected stroke, treatment in a mobile stroke unit substantially reduced median time from call for help to therapy decision. However, there was no substantial difference in the number of patients who received intravenous thrombolysis, or in neurological outcome.
