Menopause is an important physiological stage in women's life. The potential association of menopause with carotid intima-media thickness as well as with occurrence and stability of carotid plaque in Chinese female population is unclear. We conducted a population-based, cross-sectional study by recruiting 2,131 participants aged above 40 years from northeast of China. Carotid intima-media thick...
Background and Aim: Body mass index (BMI) is the most useful index used to screen children obesity. Since height and weight are determined by genetic, racial and environmental factors, body mass index can differ from one population to another. The aim of this study was to prepare the normogram of (7-120year old) children body mass index (BMI) in Birjand and to compare it with that of with the c...
BACKGROUND We have previously reported reference values for common clinical chemistry tests in healthy 70-year-old males and females. We have now repeated this study 5 years later to establish reference values also at the age of 75. It is important to have adequate reference values for elderly patients as biological markers may change over time, and adequate reference values are essential for c...
OBJECTIVE To derive optimal body mass index (BMI) and waist circumference thresholds for children and adolescents, to predict risk factor clustering. DESIGN Cross-sectional receiver operating characteristic curve analysis. SETTING The Bogalusa Heart Study, a community-based study of cardiovascular disease risk factors in early life. PARTICIPANTS A total of 2597 black and white children an...
OBJECTIVES To describe changes over time in extent of idiopathic pulmonary fibrosis (IPF) at multidetector computed tomography (MDCT) assessed by semi-quantitative visual scores (VSs) and fully automatic histogram-based quantitative evaluation and to test the relationship between these two methods of quantification. METHODS Forty IPF patients (median age: 70 y, interquartile: 62-75 years; M:F...
This paper provides a practical procedure for fusing LiDAR and photogrammetric point clouds the extraction of tree metrics. Aerial are first generated using structure-from-motion dense-matching methods. Registration is then performed an onboard global positioning system inertial measurement unit. However, due to systematic deviations, it impossible directly merge two types cloud. Therefore, urb...
