OBJECTIVE The relationship between traumatic brain injury (TBI) and the risk of dementia remains controversial. This population based study was designed to estimate and compare the risk of dementia in TBI and non-TBI individuals during the 5 year period after TBI. METHODS This study was a retrospective cohort study. Data were obtained from the(More)
OBJECT Multilevel long-segment lumbar fusion poses a high risk for future development of adjacent-segment degeneration (ASD). Creating a dynamic transition zone with an interspinous process device (IPD) proximal to the fusion has recently been applied as a method to reduce the occurrence of ASD. The authors report their experience with the Device for(More)
OBJECTIVE To compare the efficacy of percutaneous vertebroplasty (PV) with conservative therapy for patients with acute vertebral compression fractures. DESIGN Prospective, nonrandomized, comparison study. BACKGROUND The efficacy of PV has not been well established because there have been few comparative studies with conservatively treated control(More)
Magnesium sulfate and nimesulide are commonly used drugs with reported neuroprotective effects. Their combination as stroke treatment has the potential benefits of decreasing individual drug dosage and fewer adverse effects. This study evaluated their synergistic effects and compared a low-dose combination with individual drug alone and placebo.(More)
Subarachnoid hemorrhage (SAH) causes brain injury via glutamate excitotoxicity, which leads to an excessive Ca2+ influx and this starts an apoptotic cascade. Memantine has been proven to reduce brain injury in several types of brain insults. This study investigated the neuro-protective potential of memantine after SAH and explored the underlying mechanisms.(More)
BACKGROUND This retrospective cohort study was designed to assess whether there is an association between newly diagnosed dementia and the risk of stroke. METHODS From Taiwan's National Health Insurance Research Database of reimbursement claims, we identified 2811 patients with newly diagnosed dementia and 14,055 randomly selected, age-matched patients(More)
Glucagon-like peptide 1 (GLP-1) analogs protect a variety of cell types against oxidative damage and vascular and neuronal injury via binding to GLP-1 receptors. This study aimed to investigate the effects of the GLP-1 analogs exendin-4 and liraglutide on cerebral blood flow, reactive oxygen species production, expression of oxidative stress-related(More)
BACKGROUND AND PURPOSE Rebleeding in spontaneous intracerebral hemorrhage (ICH) is a major cause of morbidity and mortality among stroke survivors. Due to the links between inflammation and rebleeding, we hypothesized that the biomarkers of inflammation are associated with the pathogenesis of rebleeding in ICH. We sought to investigate whether these(More)
Traumatic brain injury (TBI) leads to important and deleterious neuroinflammation, as evidenced by indicators such as edema, cytokine production, induction of nitric oxide synthase, and leukocyte infiltration. After TBI, cerebral vascular endothelial cells play a crucial role in the pathogenesis of inflammation. In our previous study, we proved that(More)
AIM Autoimmune rheumatic diseases (ARD) are characterized by systemic inflammation and may affect multiple organs and cause vascular events such as ischemic stroke and acute myocardial infarction. However, the association between ARD and increased risk of dementia is uncertain. This is a retrospective cohort study to investigate and compare the risk of(More)
