Predicting hospital mortality using APACHE II scores in neurocritically ill patients: a prospective study.
Four versions of Acute Physiology and Chronic Health Evaluation are limited in predicting hospital mortality for neurocritically ill patients. This prospective study aimed to develop and assess the accuracy of a modified APACHE II model in predicting mortality in neurologic intensive care unit (N-ICU). A total of 653 patients entered the study. ⋯ The discrimination of the 72-h APACHE II score for cerebral infarction, intracerebral hemorrhage, and neurologic infection was satisfactory, with AU-ROC of 0.858, 0.863, and 1.000, respectively, but it was poor in discriminating for the categories of other neurologic diseases and neuromuscular disease. The results showed that our modified APACHE II model can accurately predict hospital mortality for patients in N-ICU. It is more applicable to clinical practice than the previous model because of its simplicity and ease of use.

Concomitant spinal cord and vertebral body infarction is highly associated with aortic pathology: a clinical and magnetic resonance imaging study.
The purpose of this article is to investigate the relationship between clinical features and imaging characteristics of spinal cord infarction (SCI). Twenty patients (11 women/9 men) were diagnosed at the Chang Gung Memorial Hospital between March 1993 and March 2007. Data of clinical features, possible causes and imaging findings were collected and analyzed retrospectively. ⋯ Vertebral abnormalities are not uncommon, but easily overlooked in SCI. Furthermore, concomitant SCI and vertebral body infarctions were usually located at the thoracolumbar regions, and highly associated with patients with aortic diseases (p = 0.03, chi(2) test). An understanding of the spinal cord and vertebral vascular supply greatly benefits in early diagnosis, etiological illumination, and prognostic prediction of SCI.

Metabolic syndrome increases the risk of stroke: a 5-year follow-up study in a Chinese population.
Limited information is available on the relationship between metabolic syndrome and stroke in the Chinese population. The aim of this study was to establish the prevalence of metabolic syndrome in the Chinese population and the relationship between stroke and metabolic syndrome in that population. 2,173 subjects aged 45 years and above without a history of stroke were recruited from six communities in Chongqing city, China. The participants were followed for incident stroke events (ischemic stroke and hemorrhagic stroke) for 5 years. ⋯ After 5-year follow-up, the survival rates of stroke events were 94.2% among those with metabolic syndrome and 96.9% among those without. As the number of metabolic syndrome components increased, survival rates decreased progressively, from 99.6% for individuals with none of the components to 90.1% for those with four to five components. The results showed that metabolic syndrome is highly prevalent among the Chinese adult population and is associated with an increased risk for both ischemic stroke and hemorrhagic stroke.

Randomized Controlled Trial Comparative StudyGreater improvement in quality of life following unilateral deep brain stimulation surgery in the globus pallidus as compared to the subthalamic nucleus.
While deep brain stimulation (DBS) surgery is a well-accepted treatment for Parkinson disease (PD) that improves overall quality of life (QoL), its effects across different domains of QoL are unclear. The study reported here directly compared the effects of unilateral DBS in subthalamic nucleus (STN) or globus pallidus (GPi) on QoL in 42 non-demented patients with medication-refractory PD. Patients were enrolled in the COMPARE trial, a randomized clinical trial of cognitive and mood effects of STN versus GPi DBS conducted at the University of Florida Movement Disorders Center. ⋯ Within the STN group only, declining category fluency scores correlated with poorer QoL on the communication subscale. Unilateral DBS in both STN and GPi improved QoL overall and in disparate domains 6 months after surgery. Patients receiving GPi DBS reported greater improvements that cannot be explained by differential mood or motor effects; however, verbal fluency changes may have partially contributed to lesser QoL improvements amongst STN patients.
