AIMTo assess the differences in clinical and laboratory parameters of non-hospitalized patients with deep venous thrombosis (DVT) according to the SARS-CoV-2 status. METHODSWe retrospectively ...reviewed demographic, clinical, laboratory, and ultrasound data of adult patients admitted to the Emergency Department of University Hospital Split between March 2020 and January 2021. Patients were classified into three groups: recent COVID-19 (<1 month), non-recent COVID-19 (1 to 12 months), and non-COVID-19. RESULTSFifty (47.2%) of 106 patients had a history of SARS-CoV-2 infection (23 patients in the recent COVID-19 and 27 in non-recent COVID-19 group). The three groups did not significantly differ in demographic and clinical parameters, including the location of deep venous thrombosis. The recent COVID-19 group had significantly higher neutrophils and CRP levels, and significantly lower prothrombin than the other two groups. CONCLUSIONOur results confirm the role of elevated inflammatory and coagulation response in DVT development in the first month after the infection, but not in non-recent COVID-19 or non-COVID-19 patients.

Renal artery embolism is a disease that is easily missed due to its infrequent and nonspecific presentations. Although early diagnosis and optimal thrombolytic treatment can sometimes restore renal ...function, therapeutic guidelines have not yet been established. However, early anticoagulant therapy is beneficial and selective infusion of lytic agents into renal artery has been reported with increasing frequency and efficacy if used in the early stage. We report that intra-arterial thrombolytic therapy with low dose of 35 mg recombinant tissue plasminogen activator (t-PA) may be an effective and safe strategy for the treatment of renal artery embolism, despite the period of ischemia being longer than 48 hours.
Abstract Purpose Guidewires have been reported as a useful occlusion material for large aneurysms of different locations with good short-term results. In this study we retrospectively evaluate ...long-term results of emergency embolization technique with guidewires in symptomatic internal iliac artery aneurysm (IIAA) impending rupture. Patients and methods In four patients presented with acute abdominal pain, multidetector computed tomography revealed unstable, 7–14 cm large, IIAAs. Two patients were treated with coil embolization of distal branches followed by occlusion of aneurysmal sac with guidewires. In two patients embolization of aneurysmal sac alone was performed. Results In three patients complete or near complete occlusion of the aneurysmal sac was achieved and abdominal pain ceased within hours. Two patients treated with embolization of distal iliac artery branches and aneurysmal sac developed claudication that lasted up to 1 year. Their aneurysms remained thrombosed and they were without symptoms until they died 31 and 56 months later of causes unrelated to IIAA. Two patients treated with embolization of the aneurysm alone were free of ischemic symptoms. Because of incomplete embolization of the sac in one patient open surgery treatment in a non-emergency setting was performed. Complete filling of aneurysmal sac was achieved in other patient but 2 years later his aneurysm re-opened and required open surgery treatment. Conclusion Embolization of aneurysmal sac of large IIAA with guidewires may be effective for immediate treatment of impending rupture. Long-term results were better when embolization of the aneurysmal sac was combined with embolization of distal IIA branches.
Abstract
A 69-year-old man was admitted after syncope followed with chest pain and signs of cardiac tamponade. He had undergone permanent dual-chamber pacemaker implantation 3 weeks earlier. ...Transthoracic echocardiography (TTE) confirmed a pericardial effusion, and urgent pericardial drainage was performed. Right ventricular perforation caused by active-fixation (screw-in) lead was verified by multislice computed tomography. The lead was extracted under fluoroscopy and bedside TTE monitoring in the operating room with cardiothoracic surgery backup. In the same act, the new ventricular passive-fixation lead was implanted.
Control of the work piece position is one of the most difficult and most common problems in manufacturing. This problem is in most cases solved by using an electric axis with a servo or step motor, ...servo pneumatic or classical pneumatic components. Having this in mind, a didactic set for controlling the work piece position in vertical tubes has been developed and will be described in this paper. This system has been realized by using servo pneumatics and classical pneumatics. In this system, feedback was used for controlling the work piece position in a servo pneumatic system. The feedback was obtained by using a photoelectric sensor. The developed system is a part of the laboratory equipment used by undergraduate and graduate students in the Industrial Engineering and Mechatronics study programme at the Faculty of Technical Sciences, University of Novi Sad, as well as by individuals who already work in industry. This didactic set encourages active participation of students in class and helps them with their tasks, which include learning about the structure of the set and the way of controlling the work piece position.
Istraživanja u okviru doktorske disertacije usmerena su ka razvoju metode za projektovanje i optimizaciju sistema za montažu zasnovanih na lean konceptu. Analizirani su postojeći instrumenti lean-a i ...posebno je istražen njihov uticaj na razvoj sistema za montažu i analizu ključnih parametara sistema. Na osnovu prethodnog istraživanja, izvršena je selekcija instrumenata lean koncepta koji su implementirani u metodu za projektovanje i optimizaciju sistema za montažu. Verifikacija predložene metode realizovana je na studiji slučaja optimizacije postojećeg sistema za montažu cirkulacionih pumpi. Osim navedenog, izvršeno je i projektovanje potpuno novog sistema za montažu cirkulacionih pumpi.

Implementation of product traceability is in interest of every producer because it cuts production cost and provides better security booth for buyers and suppliers. To provide traceability of product ...parts it is needed to mark each part separately. Dot peen marking is technology where data is printed on product surface by stamping with carbide needle. Research presented in this paper is focused on readability of DataMatrix 2D code made with dot peen marking method. It includes few types of materials and also different parameters of marking (code size and stamping depth).
