Quantitative ultrasound of the heel captures heel bone properties that independently predict fracture risk and, with bone mineral density (BMD) assessed by X-ray (DXA), may be convenient alternatives for evaluating osteoporosis and fracture risk. We performed a meta-analysis of genome-wide association (GWA) studies to assess the genetic determinants of heel(More)
BACKGROUND Wide-necked intracranial aneurysms have been a challenge for endovascular techniques. With the advent of adjunctive devices such as balloons or stents, recanalisation rates have decreased secondary to better packing. PURPOSE The purpose of this registry was to evaluate the safety and effectiveness of the new Low-profiled Visualized Intraluminal(More)
INTRODUCTION Inadequate calcium intake is a recognized osteoporosis risk factor. The aim of the study was to estimate calcium intake in women in the Łódż population, the influence of calcium intake on bone mineral density (BMD) and fracture incidence, as well as the relationship between calcium intake and age. MATERIAL AND METHODS This cross-sectional(More)
In mining data streams the most popular tool is the Hoeffding tree algorithm. It uses the Hoeffding's bound to determine the smallest number of examples needed at a node to select a splitting attribute. In the literature the same Hoeffding's bound was used for any evaluation function (heuristic measure), e.g., information gain or Gini index. In this paper,(More)
UNLABELLED Skinfold thicknesses are used as valid anthropometric indicators of regional body fatness. Actual population-based values for skinfold thicknesses for Polish children are not available. The purpose of this study was to provide population-based values for triceps, subscapular, and abdominal skinfold thicknesses in healthy children and adolescents.(More)
To decrease the risk of osteoporotic fractures in Poland, the Multidisciplinary Osteoporotic Forum has set up a joint Working Group including the representatives of the Polish Associations of Orthopedics and Traumatology, Rehabilitation, Gerontology, Rheumatology, Family Medicine, Diabetology, Laboratory Diagnostics, Andropause and Menopause, Endocrinology,(More)
The International Society for Clinical Densitometry Official Revised Positions on reporting of densitometry results in children represent current expert recommendations to assist health care providers determine which skeletal sites should be measured, which, if any, adjustments should be made, reference databases to be used, and the elements to include in a(More)
CONTEXT Functional hypothalamic amenorrhea (FHA) related to hypoestrogenism and hormonal status may influence skeletal homeostasis and body composition. The study aimed to evaluate hormones concentrations, body composition and bone strength in FHA cases. PATIENTS AND METHODS Total body scans using DXA method (DPX-L, GE Lunar) were performed in a group of(More)
Since the Hoeffding tree algorithm was proposed in the literature, decision trees became one of the most popular tools for mining data streams. The key point of constructing the decision tree is to determine the best attribute to split the considered node. Several methods to solve this problem were presented so far. However, they are either wrongly(More)
INTRODUCTION In the 1980s, the idea evolved that some individuals with normal weight (Metabolically Obese, Normal-Weight), who probably have increased abdominal fat, have metabolic disturbances related to obesity. This observation initiated the concept of the metabolically obese but normal-weight syndrome (MONW). Since then, there have been only a few(More)
