Classification of Ataxic Gait.

Gait disorders accompany a number of neurological and musculoskeletal disorders that significantly reduce the quality of life. Motion sensors enable high-quality modelling of gait stereotypes. However, they produce large volumes of data, the evaluation of which is a challenge.

Deep Learning for Accelerometric Data Assessment and Ataxic Gait Monitoring.

Ataxic gait monitoring and assessment of neurological disorders belong to important multidisciplinary areas that are supported by digital signal processing methods and machine learning tools. This paper presents the possibility of using accelerometric data to optimise deep learning convolutional neural network systems to distinguish between ataxic and normal gait. The experimental dataset includes 860 signal segments of 16 ataxic patients and 19 individuals from the control set with the mean age of 38.

Zero Watermarking: Critical Analysis of Its Role in Current Medical Imaging.

Medical image data plays a critical role in health care today. Whatever the context of image processing (research and educational activities, diagnostic or forensic purposes, etc.), they are supposed to be treated as highly sensitive.

Permutation Entropy and Signal Energy Increase the Accuracy of Neuropathic Change Detection in Needle EMG.

Needle electromyography can be used to detect the number of changes and morphological changes in motor unit potentials of patients with axonal neuropathy. General mathematical methods of pattern recognition and signal analysis were applied to recognize neuropathic changes. This study validates the possibility of extending and refining turns-amplitude analysis using permutation entropy and signal energy.

Prediction of coronary vessel involvement on the basis of atherosclerosis risk factor analysis.

The prediction of coronary vessel involvement by means of noninvasive tests is one of the fundamental objectives of preventive cardiology. This review describes the current possibilities of coronary vessel involvement prediction by means of ultrasonographic examination of carotid arteries, analysis of polymorphisms in the genes encoding enzymes responsible for production of nitric oxide and carbon monoxide and assessment of levels of certain proinflammatory cytokines. In the presented work these noninvasive markers are correlated with the extent of coronary vessel involvement as assessed by coronary angiography, intravascular ultrasound and virtual histology (Fig.

Traits and evolution of wing venation pattern in paraneopteran insects.

Two different patterns of wing venation are currently supposed to be present in each of the three orders of Paraneoptera. This is unlikely compared with the situation in other insects where only one pattern exists per order. We propose for all Paraneoptera a new and unique interpretation of wing venation pattern, assuming that the convex cubitus anterior gets fused with the common stem of median and radial veins at or very near to wing base, after separation from concave cubitus posterior, and re-emerges more distally from R + M stem.

[Outcomes of combined surgical and endovascular treatment of the venous thoracic outlet syndrome during 2000-2007 in the IInd Surgical Clinic of the VFN (General Faculty Hospital) and 1. LF UK (First Medical Faculty, Charles University) in Prague].

Objectives: Between 2000-2007 we performed 31 surgical procedures for thoracic outlet syndrome, two patients underwent bilateral procedure.

Methods And Results: 26 patients had venous TOS, 4 neurovascular and 1 arterial TOS. Rib resection and scalenotomy were performed at 23 patients, rib resection, scalenotomy and deliberation at 9 patients, in one case re-operation.

Endovascular treatment combined with stratified surgery is effective in the management of venous thoracic outlet syndrome complications: a long term ultrasound follow-up study in patients with thrombotic events due to venous thoracic outlet syndrome.

Thoracic outlet syndrome (TOS) is caused by compression of peripheral nerves and vascular structures along their course through the upper thoracic aperture to the axilla. The aim of our study was to analyze long-term outcomes of different treatments stratified by symptom severity. We performed a retrospective analysis of a cohort of 73 consecutive patients treated at our institution presenting with TOS-associated venous thrombotic events.

[Late complication of surgical repair of aortic coarctation: ruptured pseudoaneurysm of the aorta treated by thoracic endovascular aortic repair].

Aortic coarctation is a frequent congenital defect requiring early surgical treatment. Late complications of these surgical procedures can be fatal as in the case of a ruptured anastomotic pseudoaneurysm. We present a case of a 49-year-old man presenting with hemorrhagic shock due to this complication who was successfully treated by endovascular techniques with implantation of two stent grafts.

Regulation of direct supplemental payments for services covered by the public health insurance in a comparative perspective.

In modem societies, people are strongly urged to get the best health care for themselves and their families. Although controlled costs of the health care system may be an important goal for society as a whole, the individual patient is seldom satisfied with being an object of health care rationing. When, due to financial constraints, the health services covered by the public programs become rationed and their quality is perceived as decreasing, patients tend to contract with the providers directly.

Use of 3D geometry modeling of osteochondrosis-like iatrogenic lesions as a template for press-and-fit scaffold seeded with mesenchymal stem cells.

Computed tomography (CT) is an effective diagnostic modality for three-dimensional imaging of bone structures, including the geometry of their defects. The aim of the study was to create and optimize 3D geometrical and real plastic models of the distal femoral component of the knee with joint surface defects. Input data included CT images of stifle joints in twenty miniature pigs with iatrogenic osteochondrosis-like lesions in medial femoral condyle of the left knee.

Patient rights protection in the Czech Republic: challenges of a transition from Communism to a modern legal system.

The post-Communist countries in Central Europe, including the Czech Republic, underwent a rapid transformation of their legal systems, within which the concept of patient rights passed through revolutionary changes. This process however often left significant gaps in patient rights protection. There are practical difficulties for patients in defending their rights before the courts, such as problems with obtaining evidence and independent expert opinions, long delays and high costs of court proceedings, strict burden of proof rules and low compensation levels.
