Dysphagia and swallowing-related quality of life in Friedreich ataxia. Adam P. Vogel, Sophie E. Brown, Joanne E. Folker, Louise A. Corben, Martin B. Delatycki;
Journal of Neurology, December 2013. DOI 10.1007/s00415-013-7208-4

Keywords: Dysphagia, Friedreich ataxia (FRDA), quality of life, oral-motor examination, speech and swallowing, incoordination, weakness, spasticity.

Role of Frataxin, a Protein Implicated in Friedreich Ataxia, in Making Iron-Sulfur Clusters

Role of Frataxin, a Protein Implicated in Friedreich Ataxia, in Making Iron-Sulfur Clusters. The Journal of Biological Chemistry, 288, 36787. December 27, 2013; 10.1074/jbc.P113.525857

The authors concluded that their work “may help develop a drug for treating Friedreich ataxia associated with frataxin deficiency.”

Erythropoietin and the heart: Physiological effects and the therapeutic perspective

Erythropoietin and the heart: Physiological effects and the therapeutic perspective. Fabian Sanchis-Gomar, José Luis Garcia-Gimenez, Helios Pareja-Galeano, Marco Romagnoli, Carme Perez-Quilis, Giuseppe Lippi; International Journal of Cardiology, Available online 18 December 2013, http://dx.doi.org/10.1016/j.ijcard.2013.12.011

Keywords: Myocardial infarction; cardioprotection; remodelling; EpoR; angiogenesis; apoptosis; inflammation; pleiotropic actions; Friedreich’s ataxia

If rhEpo or its analogues improve(s) the muscle and mitochondrial function it would help improve the cardiac function. However, none of these studies and clinical trials mentioned the long-term effect of rhEpo on the heart of FRDA. Thus, an effort designing a clinical trial involving treatments a long term in FRDA patients are strongly recommended.

Italy blocks controversial stem cell therapy

Italy blocks controversial stem cell therapy. Nature Biotechnology 31, 1062 (2013); doi:10.1038/nbt1213-1062a
Published online 06 December 2013

The Italian government withdrew its support for a controversial stem cell therapy trial before it was due to start, prompting an outcry from patients. The decision was announced by Health Minister Beatrice Lorenzin on October 10, after an ad hoc scientific committee deemed the treatment too risky and undefined. In…
