|Título:||Fluoxetine for motor recovery after acute intracerebral hemorrhage (FMRICH): Study protocol for a randomized, double-blind, placebo-controlled, multicenter trial|
|Fecha de publicación:||2014|
|Resumen:||New construction blocks for nanomaterials have been found in nature itself: viruses. Synthetic methods to modify them are relevant for bionanomaterials design. In this paper, a method is presented that takes advantage of the natural functional groups in the fd virus structure to decorate them with gold nanoparticles. The method employs a bioconjugation reaction in which cysteine molecules are appropriately bonded, mediated by carbodiimides, to carboxyl and amine groups in the virus capsid proteins. fd virus with one gold nanoparticle at the tip end and gold nanowire-like structures were obtained. We can discriminate the different synthesized structures, using surface enhanced Raman spectroscopy in conjunction with principal component analysis. The general procedure developed here is a promising tool to determine how viruses are modified after a bioconjugation reaction.

Silos, H.",,"2013",,"Background: Spontaneous, nontraumatic intracerebral hemorrhage (ICH) is a subtype of stroke that causes a great amount of disability and economic and social burden. This is particularly true in developing countries where it accounts for between 20% and 50% of all strokes. Pharmacological and surgical interventions have been attempted to reduce the mortality and disability caused by ICH, with unsuccessful results. Recently, the use of fluoxetine in addition to physical rehabilitation has been proven useful to improve motor recovery following cerebral infarct. The purpose of this study is to test whether a 3-month treatment with fluoxetine enhances motor recovery in nondepressed patients with acute intracerebral hemorrhage.Methods/design: Our study is a randomized, double-blind, placebo-controlled, multicenter clinical trial. We will recruit 86 patients with intracerebral hemorrhage of both sexes, aged >18 years, from four Mexican hospitals. The patients will receive either 20 mg of fluoxetine or a placebo once daily for 90 days. The primary outcome is the mean change in the Fugl-Meyer Motor Scale score between inclusion (day 0) and day 90. The secondary outcomes will be changes in the Barthel Index, the Modified Rankin scale and the National Institutes of Health stroke scale. The outcomes will be measured at day 42 7days and at day 90, for a total of four visits with each subject (at screening and at 0, 42 and 90 days).Discussion: Current guidelines recommend early supported hospital discharge and home-based rehabilitation programs as the only cost-effective intervention to aid the recovery of patients with intracerebral hemorrhage. Nevertheless, such interventions are dependent on available resources and funding, which make them very difficult to implement in developing countries. We believe that the identification of a helpful pharmacological intervention to aid the motor recovery of these patients will constitute a breakthrough that will have a major impact in reducing the burden of disease caused by this subtype of stroke worldwide, especially in the developing world.Trial registration: Current Controlled Trials NCT01737541.
