IPMed trial — application of impedance cardiography to monitoring of cardiovascular system

Zaburzenia hemodynamiczne stanowią drugą najczęstszą przyczynę zgonu u chorych po udarze mózgu. Istniejące standardy postępowania nie uwzględniają pełnej diagnostyki układu sercowo-naczyniowego u tych chorych. W niniejszej pracy przedstawiono wieloośrodkowy projekt IPMed, który jest próbą aplikacji kardiografii impedancyjnej (ICG) do monitorowania hemodynamiki pacjentów po udarze mózgu.Hemodynamic failure is the second most important cause of death in patients with stroke. Existing standards of treatment do not include full cardiovascular assessment in these patients. This article presents a multicenter project IPMed which is an application of impedance cardiography (ICG) to monitoring of hemodynamics in patients with stroke

Depth Images Filtering In Distributed Streaming

In this paper, we propose a distributed system for point cloud processing and transferring them via computer network regarding to effectiveness-related requirements. We discuss the comparison of point cloud filters focusing on their usage for streaming optimization. For the filtering step of the stream pipeline processing we evaluate four filters: Voxel Grid, Radial Outliner Remover, Statistical Outlier Removal and Pass Through. For each of the filters we perform a series of tests for evaluating the impact on the point cloud size and transmitting frequency (analysed for various fps ratio). We present results of the optimization process used for point cloud consolidation in a distributed environment. We describe the processing of the point clouds before and after the transmission. Pre- and post-processing allow the user to send the cloud via network without any delays. The proposed pre-processing compression of the cloud and the post-processing reconstruction of it are focused on assuring that the end-user application obtains the cloud with a given precision

Ischemic stroke in general practice – risk factors, prognosis – prospective single center study

Background. Ischemic stroke is one of the leading causes of death and disability in Poland, in the European Union and in the United States. Awareness related to the risk factors, particularly the modifiable ones, is of crucial importance in general practice and may improve early and long-term prognoses. Objectives. The aim of this study was to assess the risk factors and half-year survival rate in patients with ischemic stroke in the period 2011–2015. Material and methods. The study involved 70 patients (30 women and 40 men) with ischemic stroke. The mean age of the patients was 71.4 ± 9.6 years (71.7 ± 10.8 years in women and 71.2 ± 8.6 in men). On the basis of an interview, physical examination and additional tests the risk factors of cardiovascular diseases were determined. Half-year survival data were obtained based on telephone surveys and the records of the Office of the Registrar of Vital Statistics. Results. It was found that the most common risk factors were arterial hypertension, overweight states and obesity, dyslipidemia, coronary artery disease, atrial fibrillation and smoking (67.1%; 65.7%; 38.6%; 38.6%; 28.6%; 24.3%, respectively). 39 out of 47 patients with arterial hypertension (83.0%) took hypotensives, and out of 20 patients with atrial fibrillation only 9 patients (45%) took anticoagulants. The half-year survival rate was 84.3% (59 survivors). 3 patients died in hospital (in the first week after stroke) and 8 patients died following hospital discharge, during ambulatory treatment. Conclusions . The risk of death is highest during the first 3 months after an ischemic stroke episode. The general practitioner plays a central role in the prevention of ischemic stroke

Konstrukcja bazy danych dla systemu wspomagania diagnostyki chorób przewodu pokarmowego

The article briefly presents the process of diagnosing gastrointestinal diseases and discusses existing techniques of supporting it with automatic analysis of video from gastrointestinal examinations. Further, the process of designing a specialized medical database is described. The main goal of the created database is to provide data for the training of automatic classifiers of gastrointestinal diseases. Finally, the collected data and acquired results are presented.W artykule krótko przedstawiono charakterystykę procesu diagnostyki chorób przewodu pokarmowego oraz istniejące techniki wspomagania go na bazie analizy zdjęć z badań endoskopowych. Szczegółowo opisano proces tworzenia specjalistycznej bazy danych medycznych, której przeznaczeniem jest wspomaganie procesu uczenia klasyfikatorów chorób przewodu pokarmowego. Na koniec przedstawiono zebrane w bazie dane oraz uzyskane efekty
