Age is an important prognostic factor in the outcome of acute coronary syndromes (ACS). A substantial percentage of patients who experience ACS is more than 75 years old, and they represent the fastest-growing segment of the population treated in this setting. These patients present different patterns of responses to pharmacotherapy, namely, a higher ischemic and bleeding risk than do patients under 75 years of age. Our aim was to identify whether the currently available ACS ischemic and bleeding risk scores, which has been validated for the general population, may also apply to the elderly population. The second aim was to determine whether the elderly benefit more from a specific pharmacological regimen, keeping in mind the numerous molecules of antiplatelet and antithrombotic drugs, all validated in the general population. We concluded that the GRACE (Global Registry of Acute Coronary Events) risk score has been extensively validated in the elderly. However, the CRUSADE (Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA Guidelines) bleeding score has a moderate correlation with outcomes in the elderly. Until now, there have not been head-to-head scores that quantify the ischemic versus hemorrhagic risk or scores that use the same end point and timeline (e.g., ischemic death rate versus bleeding death rate at one month). We also recommend that the frailty score be considered or integrated into the current existing scores to better quantify the overall patient risk. With regard to medical treatment, based on the subgroup analysis, we identified the drugs that have the least adverse effects in the elderly while maintaining optimal efficacy.

1|INTRODUCTION Capecitabine is an oral prodrug of 5-fluorouracil(5-FU),which is widely used for adjuvant and neoadjuvant chemotherapy of different solid tumors,particularly breast and colorectal cancers.1 Neurotoxicity of capecitabine has been consistently reported as capecitabine-induced toxic leukoencephalopathy,which includes bilateral lesions in the corpus callosum and corticospinal tract presenting as acute or delayed central nervous system toxicity.2 This side effect requires discontinuation of chemotherapy3;however,neurological symptoms due to capecitabine are reported to be usually reversible upon drug withdrawal.

Reorganization of spinal neural circuitry and functional recovery after spinal cord injury

引用

Neural Regeneration Research 2015年第2期10卷 201-202页

作者： Raffaele Nardone eugen Trinka Department of Neurology Christian Doppler Klinik Paracelsus Medical University Spinal Cord Injury and Tissue Regeneration Center Paracelsus Medical University Department of Neurology Franz Tappeiner Hospital

The ability of the adult central nervous system to reorganize its circuits over time is the key to understand the functional improvement in subjects with spinal cord injury （SCI）. Adaptive changes within spared neuronal circuits may occur at cortical, brainstem, or spinal cord level, both above and below a spinal lesion （Bareyre et al., 2004）. At each level the reorganization is a very dynamic process, and its degree is highly variable, depending on several factors, including the age of the subject when SCI has occurred and the rehabilitative therapy. The use of electrophysiological techniques to assess these functional changes in neural networks is of great interest, because invasive methodologies as employed in preclinical models can obviously not be used in clinical studies.

To the Editor,Marfan syndrome is an autosomal dominant disorder of connective tissue caused by mutations in the gene encoding a matrix component of microfibrils;fibrillin-1(FBN1),with an incidence of about 1-3 per 10,000 individuals.2.3 Cardinal manifestations include proximal aortic aneurysm,dislocation of the ocular lens,and long-bone *** ectasia,which is defined as a ballooning or significant widening of the dural sac or neural root sleeves,is also a common finding in these patients,which is reported to present in more than 60%of cases and is considered a major criterion for the clinical diagnosis of this syndrome.
