Using the National Institute of Health Stroke Scale to predict dysphagia in acute ischemic stroke.
Oropharyngeal dysphagia is a common manifestation in acute stroke. Aspiration resulting from difficulties in swallowing is a symptom that should be considered due to the frequent occurrence of aspiration pneumonia that could influence the patient's recovery as it causes clinical complications and could even lead to the patient's death. The early clinical evaluation of swallowing disorders can help define approaches and avoid oral feeding, which may be detrimental to the patient. This study aimed to create an algorithm to identify patients at risk of developing dysphagia following acute ischemic stroke in order to be able to decide on the safest way of feeding and minimize the complications of stroke using the National Institutes of Health Stroke Scale (NHISS). ⋯ The NIHSS is highly sensitive (88%) and specific (85%) in detecting dysphagia; a score of 12 may be considered as the cutoff value. The creation of an algorithm to detect dysphagia in acute ischemic stroke appears to be useful in selecting the optimal feeding route while awaiting a specialized evaluation.

ReviewAdvances in neuroprotective strategies: potential therapies for intracerebral hemorrhage.
Intracerebral hemorrhage (ICH) is associated with higher mortality and morbidity than any other form of stroke. However, there currently are no treatments proven to improve outcomes after ICH, and therefore, new effective therapies are urgently needed. ⋯ We extensively reviewed the current understanding of ICH pathophysiology as well as promising experimental neuroprotective agents with particular focus on their mechanisms of action. Continued advances in ICH knowledge, increased understanding of neuroprotective mechanisms, and improvement in the ability to modulate molecular and pathologic events with multitargeting agents will lead to successful clinical trials and bench-to-bedside translation of neuroprotective strategies.

Multicenter Study Comparative StudyRisk of recurrent cerebrovascular events in patients with cryptogenic stroke or transient ischemic attack and patent foramen ovale: the FORI (Foramen Ovale Registro Italiano) study.
The optimal management of patients with cryptogenic ischemic stroke found to have a patent foramen ovale (PFO) at diagnostic workup remains unclear. The aims of this observational multicenter study were to evaluate: (1) the risk of recurrent cerebrovascular events in patients with cryptogenic minor ischemic stroke or transient ischemic attack (TIA) and PFO who either underwent percutaneous PFO closure or received only medical treatment, and (2) the risk factors associated with recurrent events. ⋯ The results of this observational, nonrandomized study suggest that PFO closure might be superior to medical therapy for the prevention of recurrent stroke. Periprocedural complications were the trade-off for this clinical benefit. Controlled randomized clinical trials comparing percutaneous closure with medical management are required.

Randomized Controlled TrialCilostazol improves outcome after subarachnoid hemorrhage: a preliminary report.
Cerebral vasospasm (VS) is the most common cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage (SAH). Reversal of VS by intra-arterial infusion of cyclic adenosine monophosphate (cAMP)-elevating agents has been reported; however, the preventive role in the development of VS is not fully understood. This study is designed to evaluate the possible efficacy of using cilostazol, a selective inhibitor of phosphodiesterase type 3 and a cAMP-elevating agent, in patients with SAH. ⋯ Cilostazol may improve outcomes after SAH, but further double-blind, placebo-controlled studies are required for a definitive conclusion.
