Randomized Controlled Trial Multicenter Study
Development of a short form of Stroke-Specific Quality of Life Scale for patients after aneurysmal subarachnoid hemorrhage.
The identification of aneurysmal subarachnoid hemorrhage (aSAH) patients with a decrease in health-related quality of life (HRQOL) is challenging. Stroke-Specific Quality of Life (SS-QOL) Scale is one of the commonest disease-specific quality of life measures initially developed and validated for ischemic stroke patients. A disadvantage is subject burden and a short form is more practical to use in clinical and research setting. ⋯ The 12-item Chinese version of SSQOL-a has a satisfactory internal consistency and criterion validity for SAH patients at 12 month assessments.

Guillain-Barre syndrome (GBS) is an acute polyradiculoneuropathy with varied severity of presentation. ⋯ Detailed evaluation of the clinical and electrophysiological profile may help in predicting the functional outcome and need for mechanical ventilation in patients with GBS.

Cerebrospinal fluid (CSF) examination is considered important in the diagnosis of neurosarcoidosis, however, data on whether and how CSF parameters may be related to MRI findings and clinical disease activity of patients with neurosarcoidosis are scarce. ⋯ CSF abnormalities in neurosarcoidosis are most pronounced in patients with diffuse leptomeningeal enhancement on MRI. CSF analyses may thus aid in the distinction of different radiographic and pathologic manifestations of neurosarcoidosis. Furthermore, CSF examinations may allow monitoring disease activity in patients with neurosarcoidosis.

Alzheimer's disease (AD) is characterized by a deficit in motor and spatial learning-memory and alteration of non-cognitive behavior. The generation of transgenic mice with presence of AD pathologies that cause learning and memory deficits has led to improved understanding of the behavioral and pathophysiological processes underlying AD. A novel APP/PS1 mouse model in the senescence accelerated mouse prone 8 (SAMP8) background--SAMP8 APP/PS1 was generated. ⋯ In contrast, C57 APP/PS1 and SAMP8 wild type mice were inconspicuous in all of these tasks and properties except C57 APP/PS1 mice which showed motor memory impairment in the shuttle box task at 9 months old. Standard senescence-associated beta-galactosidase (SA-beta-GAL) staining and amyloid beta (Aβ) immunohistochemistry showed more severe pathological changes in the SAMP8 APP/PS1 mice. SAMP8 APP/PS1 mice exhibited earlier deficits in their non-cognitive and cognitive behaviors which are coincident in the AD patient and the results suggest that this new type of mice might be a better model for studying the age-related dementia of the Alzheimer type and for assessing the potential therapeutic agents for AD.
