Review Meta Analysis
The efficacy of temozolomide for recurrent glioblastoma multiforme.
The efficacy of temozolomide (TMZ) in recurrent glioblastoma multiforme (GBM) has been evaluated by several clinical trials. A meta-analysis to assess the overall efficacy of TMZ in the treatment of recurrent GBM was carried out by the authors. ⋯ Temozolomide is effective for recurrent GBMs, and its efficacy may be increased with metronomic schedule and high average daily dose (>100 mg/m(2) ).

Cardiovascular autonomic failure is the second most common dysautonomic feature of α-synucleinopathies and has significant impact on daily activities and quality of life. Here we provide a systematic review of cardiovascular autonomic failure in α-synucleinopathies, emphasizing its impact on cognitive functions and disease outcomes. ⋯ Altered cerebral perfusion, vascular pressure stress, and related disruption of the blood-brain barrier may also contribute to the white matter hyperintensities and cognitive dysfunction frequently found in patients affected by neurocardiovascular instability. These findings support the hypothesis that cardiovascular autonomic failure may play a negative prognostic role in α-synucleinopathies and suggest that precocious screening and therapeutic management of cardiovascular autonomic failure may positively impact disease course.
