BACKGROUND AND STUDY AIMS Complete Barrett's excision (CBE) of short-segment Barrett's high grade dysplasia (HGD) and early esophageal adenocarcinoma by stepwise endoscopic resection is a precise staging tool, detects covert synchronous disease, and may produce a sustained treatment response. Esophageal stricture is the most commonly reported complication(More)
The static/dynamic changes of gas exchange, heart rate (HR) and blood pressure in terms of work rate (WR) and WR changes in ramp exercise were investigated by cardio-pulmonary exercise tests (CPETs) in hyperhidrosis patients before (W0), one week (W1) and four weeks (W4) after bilateral T2-sympathectomy. Accompanied by constant oxygen consumption and WR at(More)
BACKGROUND Sleepiness-at-the-wheel has been identified as a major cause of highway accidents. The aim of our study is identifying the candidate measures for home-based screening of sleep disordered breathing in Taiwanese bus drivers, instead of polysomnography. METHODS Overnight polysomnography accompanied with simultaneous measurements of alternative(More)
OBJECTIVE The aim of the current study was to investigate whether changes in post- to pre-overnight sleep systolic blood pressure (SSBP) are associated with sleep respiratory disturbance, pro-inflammatory state, and metabolic situation in patients with sleep-disordered breathing (SDB). METHODS Anthropometry, sleep polysomnography, biochemical markers, and(More)
Both proteinuria and obstructive sleep apnea (OSA) are associated with cardiovascular events and consequent mortality. To examine whether age, OSA, diabetes, and obesity are potential predictors of proteinuria, a data-driven analysis was performed to delineate a potential categorical classification algorithm. In this cross-sectional community-based cohort(More)
To assess the physiological meanings of the detrended fluctuation analysis (DFA) slope α and its relationship to spectral measures in heart rate variability, this study investigated changes of α and its corresponding spectral measures over various night-sleep stages. The overall DFA α and natural-logarithm-transformed power values of the spectral parameters(More)
BACKGROUND Sleep-disordered breathing (SDB) and cardiometabolic risk factors are male prevalent. OBJECTIVE This study investigated whether gender differences remained prominent after matching for the apnea hypopnea index (AHI) and postmenopause. METHODS In a retrospective analysis of 350 eligible SDB patients, female patients were matched with male(More)
BACKGROUND AND STUDY AIMS Narrow-band imaging (NBI) is a new imaging methodology for improving the detection rate of gastrointestinal lesions. We aimed to evaluate perception of images by NBI and corresponding standard white-light-endoscopy (WLE) using a computer-guided eye-tracking system. METHODS A total of 23 NBI images of various lesions with the 23(More)
