The outcomes at discharge for ruptured cerebral aneurysms after subarachnoid hemorrhage (SAH) were investigated using data from the Japanese stroke databank. Among 101,165 patients with acute stroke registered between 2000 and 2013, 4693 patients had SAH caused by ruptured saccular aneurysm. Of these, 3593 patients (1140 men and 2453 women; mean age 61.3 ± 13.7 years) were treated by surgical clipping (SC) and/or endovascular coiling (EC). The outcomes of modified Rankin scale (mRS) at discharge were compared between the SC and EC groups...

BACKGROUND: Stroke often causes functional decline in patients. Therefore, after the acute phase, many patients require post-acute care (PAC) to maximize their functional progress, reduce disability, and make it possible for them to return to their home and community. PAC can be provided in different settings. Taiwan's National Health Insurance (NHI) proposed a PAC pilot program, effective since 2014, for stroke patients that allowed patients with the potential for functional improvement to receive PAC rehabilitation in regional or community hospitals...

The multi-industrial applications of zinc oxide nanomaterials (ZnO NMs) lead to increasing exposure to humans. Though the ZnO nanoparticles toxicity had been evaluated previously, toxicity of other forms of ZnO nanomaterials has not been evaluated. In this study, cytotoxicity and genotoxicity of four different types of ZnO NMs were evaluated using human peripheral blood lymphocytes (HPBL). In addition, the effect of anti-oxidants on ZnO NMs induced toxicity was also evaluated. Our results suggest that, size and shape of the nanomaterials have profound effects on their toxicity...
