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)
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)
BACKGROUND Bone fractures generate significant social costs, particularly in highly developed countries. This study was aimed at defining the number of hip fractures in Poland and evaluating absolute risk of fractures of this type within a period of 10 years and to the end of life. MATERIAL/METHODS Figures concerning hip fractures in the Mazowsze Province(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)
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. A total(More)
One of the most popular tools for mining data streams are decision trees. In this paper we propose a new algorithm, which is based on the commonly known CART algorithm. The most important task in constructing decision trees for data streams is to determine the best attribute to make a split in the considered node. To solve this problem we apply the(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)
The Shouldice method and other tissue-based techniques are still acknowledged to be acceptable for primary inguinal hernia repair according to the European Hernia Society guidelines. Desarda’s technique, presented in 2001, is an original hernia repair method using an undetached strip of external oblique aponeurosis. This randomized trial compared outcomes(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)
