OBJECTIVE The principal objective of this study was to evaluate serial weight changes in athletes during 12- and 24-hour ultra-marathons and to correlate these changes with athletic performance, namely the distance covered. DESIGN This was a prospective study. SETTING The 2003 Soochow University international ultra-marathon. PARTICIPANTS Fifty-two(More)
OBJECTIVE To explore the population-level utilization and factors associated with the use of inpatient stroke rehabilitation services under a single-payer government-based National Health Insurance (NHI) program in Taiwan. STUDY DESIGN Retrospective cohort study based on claims data. METHODS Inpatients with stroke were sampled from a nationally(More)
The effects of aging on the electroencephalogram (EEG) power spectra of 8- and 60-week-old Wistar–Kyoto rats were examined during the waking baseline and treadmill exercise. Using continuous and simultaneous recordings of EEG and electromyogram signals, this study demonstrated that the alpha (10–13 Hz), theta (6–10 Hz), and delta (0.5–4 Hz) powers of the(More)
Health-related physical fitness has decreased with age; this is od immense concern to adolescents. School-based health intervention programs can be classified as either population-wide or high-risk approach. Although the population-wide and risk-based approaches adopt different healthcare angles, they all need to focus resources on risk evaluation. In this(More)
BACKGROUND Stroke is the leading cause of adult disability and mortality in Taiwan, resulting in a tremendous burden on the healthcare system. The purpose of this study was to characterize disease burden by evaluating readmissions, mortality, and medical cost during the first year after acute stroke under the National Health Insurance (NHI) program.

The aim of this study was to investigate the effect of mountain living conditions and high altitude hiking activities on glucose tolerance. In study I, we performed an oral glucose tolerance test on nine untrained subjects before and after 3 days of mountain living. In study II, the same measurement was used to determine the effect of high altitude hiking(More)
OBJECTIVE To evaluate the prevalence and characteristics of acute kidney injury (AKI) in 100-km ultramarathon runners. DESIGN Prospective observational study. SETTING The 2011 Soochow University ultramarathon, in which each athlete ran for 100 km. PARTICIPANTS All Taiwanese entrants who participated in the 100-km race and lived in the northern part of(More)
BACKGROUND Visual disturbances after high-altitude exposure were first reported in 1969. Manifestations may include retinal hemorrhage, papilledema, and vitreous hemorrhage. METHODS We observed a group of 6 experienced climbers who ascended Mt Aconcagua to an altitude of 6,962 m in February 2007. Visual acuity study, intraocular pressure study, visual(More)
OBJECTIVE Cost-effectiveness analysis (CEA) of stroke management was evaluated in three care models: Neurology/Rehabilitation wards (NW), Neurosurgery wards (NS), and General/miscellaneous wards (GW) under a universal health insurance system. METHODS From 1997 to 2002, subjects with first-ever acute stroke were sampled from claims data of a nationally(More)
The feasibility of a real-time electrocardiogram (ECG) transmission via satellite phone from Mount Everest to determine a climber's suitability for continued ascent was examined. Four Taiwanese climbers were enrolled in the 2009 Mount Everest summit program. Physiological measurements were taken at base camp (5300 m), camp 2 (6400 m), camp 3 (7100 m), and(More)
