Kultura sigurnosti je set vrijednosti, znanja, vještina, stavova i prakse na individualnom i institucionalnom nivou organizacije radioterapijskog procesa koji uspostavlja način rada u kojem sigurnost i zaštita zdravlja predstavljaju prioritet prilikom obavljanja radnih zadataka. Razvoj kulture sigurnosti na individualnom i institucionalnom nivou postalo je jedno od ključnih sigurnosnih pitanja u savremenoj radioterapiji. Cilj ovog istraživanja je procijeniti mogućnost upotrebe elektronskog sistema za prijavljivanje incidenata u razvoju kulture sigurnosti kod zdravstvenih profesionalaca u radioterapiji i mogućnost izgradnje sistemske primjene seta vrijednosti koji omogućava obavljanje svih radnih zadataka u radioterapiji uz davanje maksimalnog priorieta sigurnosti. Kao instrument istraživanja korišten je elektronski sistem za prijavljivanje incidentata u formi strukturiranog kompjuterskog intervjua prema ROSEIS metodologiji. Na osnovu informacija prikupljenih pomoću sistema napravljena je procjena razvijenosti različitih segmenata kulture sigurnosti, predložene mjere na njenom razvoju i poboljšanju, te data pocjena njihove efikasnosti u unaprijeđenju sigurnosti u radioteapiji. Razvijena kultura sigurnosti u radioterapijskom radnom okruženju može značajno unaprijediti kvalitet radioterapijskog tretmana, reducirati pojavu incidenata, poboljšati efikasnost i efektivnost radioterapijskog tretmana. Razvoj kulture sigurnosti ne podrazumijeva samo uspostavu standardnog seta pravila, nego i promjenu stavova, ponašanja i profesionalne prakse na individualnom i institucionalnom nivou.

Introduction: Hypothyroidism is a common disorder of the endocrine system caused by insufficient biologically active hormones at the tissue level or the inability of the tissue to utilize thyroid hormones. Iron plays a crucial role in the synthesis and metabolism of thyroid hormones, and it is stored in the body as ferritin. We aimed to evaluate the correlation between serum ferritin (SF) levels and thyroid hormone panel levels in both hypothyroid and euthyroid subjects. Methods: In 2022, a matched case–control study was conducted. The study involved participants with hypothyroidism and a control group (n = 53). The levels of thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), and SF were measured using the chemiluminescence immunoassay on a Mindray Cl 900-i analyzer (Shenzhen Mindray Bio-Medical Electronics Co., China). Results: The hypothyroid group had TSH levels that were significantly higher (10.76 [8.54-18.76] vs. 1.76 [1.26-2.58]; p < 0.001) and SF concentrations that were significantly lower (39.08 [21.15-45.70] vs. 54.09 [41.41-71.82]; p < 0.001) compared to the control group. In both male and female subjects of the hypothyroid group, a strong negative correlation was found between SF concentration and TSH levels ([Rho = −0.855,p < 0.01]; [Rho = −0.747; p < 0.01]). In female subjects of the hypothyroid group, a weak positive correlation was found between SF concentration and fT3 (Rho = 0.488; p < 0.05). In the euthyroid group, a correlation of the same strength and direction was found for fT4 (Rho = 0.366; p < 0.05). Conclusion: Research results indicate a correlation between lower SF concentrations and hypothyroidism, which is of particular importance for understanding the etiopathogenesis, diagnosis, monitoring, and treatment modalities of patients with hypothyroidism.

Pravilnom pripremom hrane moguće je spriječiti većinu hranom prenosivih bolesti. Značajni napori uloženi u usaglašavanje legislative na širim geografskim područjima, rezultovali su formiranjem općeprihvaćenog stava da je većina kupljenih namirnica sigurna za konzumiranje. Međutim, neophodno je da potrošači nastave dobre prakse rukovanja, pripremanja i čuvanja namirnica u domaćinstvima. Ovo istraživanje je provedeno kao presječna, deskriptivno-analitička i eksperimentalna studija u periodu novembar 2020. – juli 2021. godine. Mikrobiološka analiza briseva je provedena u akreditovanoj laboratoriji Odjela za mikrobiološku analizu namirnica, voda i predmeta opšte upotrebe pri Zavodu za javno zdravstvo Federacije Bosne i Hercegovine. U domaćinstvima je uzorkovano po 7 briseva radnih površina i pribora u kuhinjama (n = 2681) u skladu sa smjernicama standardne metode BAS EN ISO 18593:2019 – Horizontalne metode za uzimanje uzoraka sa površine. U više od polovine domaćinstava (61,5%) izolovane su ciljane bakterije u vrijednostima iznad referentnih. Najveća odstupanja u bakteriološkoj ispravnosti utvrđena su na radnim površinama u kuhinjama (45,8%), daskama za rezanje (34,1%) i slavinama (34,1%). Staphylococcus aureus je izolovan u 153, Enterobacteriacea u 151, a aerobne bakterije u 286 domaćinstava. Prema kategorizaciji ukupnog rizika, 17% domaćinstava na području Kantona Sarajevo spada u kategoriju visokog rizika od hranom prenosivih bolesti u svojim domaćinstvima. Obzirom da javnost nije upoznata sa rizikom u kojem se nalazi, smatramo da je što hitnije potrebno poduzeti korake u podizanju kolektivne svijesti o javno-zdravstvenom značaju sigurnosti hrane u domaćinstvima.

Abstract Background  Many recent studies show that exoscopes are safe and effective alternatives to operating microscopes (OM). Developments of robotics and automation are present in neurosurgery with the appearance of a newer device such as RoboticScope (RS) exoscope with a digital three-dimensional (3D) image and a head-mounted display. The body of the RS is connected to a six-axis robotic arm that contains two video cameras, and serves as stereovision. This robotic arm allows accurate 3D camera motions over the field of view, giving the user a great degree of freedom in viewpoint selection. The surgeons may specify the direction and speed of the robotic arm using simple head movements when the foot pedal is pressed. Since its development in 2020, the RS has occasionally been used in neurosurgery for a multitude of procedures. Methods  This study showcases vessel microanastomosis training on chicken legs using the RS. The aim of this study is to demonstrate the feasibility of the RS without a comparative analysis of the standard OM. The study was conducted in 2023 during a month-long trial period of the device at the Department of Neurosurgery of the Clinical Center of the University of Sarajevo. All procedures including RS-assisted anastomosis were performed by a neurosurgeon in anastomosis training (A.A.) supervised by a senior vascular neurosurgeon (E.B.). For the purpose of the study, we evaluated occlusion time in minutes, bypass patency with iodine, and overall satisfaction of the trainee in terms of light intensity, precision of automatic focus, mobility of the device, ergonomics, and convenience of the helmet. Results  Ten RS-assisted microanastomoses were performed by interrupted suturing technique with 10.0 nylon thread. Bypass training included seven “end-to-side,” two “end-to-end,” and one “side-to-side” microanastomoses. The smallest vessel diameter was 1 mm. Occlusion time improved by training from 50 to 24 minutes, with contrast patency of the anastomoses in all cases without notable leakage of the contrast, except one case. Complete satisfaction of the trainee was achieved in 7 out of 10 cases. During this period, we also performed different RS-assisted surgeries including a single indirect bypass, convexity brain tumor resection, and microdiscectomies. Conclusion  RS provides a new concept for microanastomosis training as an alternative or adjunct to the standard microscope. We found a full-time hands-on microsuturing without the need for manual readjustment of the device as an advantage as well as instant depth at automatic zooming and precise transposition of the focus via head movements. However, it takes time to adapt and get used to the digital image. With the evolution of the device helmet's shortcomings, the RS could represent a cutting-edge method in vessel microanastomosis in the future. Nevertheless, this article represents one of the first written reports on microanastomosis training on an animal model with the above-mentioned device.

Background. The management of breast cancer treatments within the limitations of family, social, and professional life is emotionally burdening and negatively affects physical, psychological, and social well-being, reducing the overall quality of life of patients and their families. Methods: This cross-sectional descriptive–analytical study was conducted from March to August 2023 at the “Dr. Radivoj Simonović” General Hospital in Sombor. A total of 236 breast cancer patients participated in this study. The research was conducted using the following instruments: a questionnaire on sociodemographic and clinical characteristics of patients, the Berlin Social-Support Scales—for assessing social support—and the Connor–Davidson Resilience Scale—for assessing resilience. This study aimed to determine the predictors and levels of social support and resilience of breast cancer patients. We also wanted to examine whether resilience is a mediator between patients’ sociodemographic and clinical characteristics and levels of social support. Results: The total average value of social support was 3.51 ± 0.63, while on the resilience scale, the respondents achieved a total average score of 52.2 ± 9.63. Perceived and actually received social support of breast cancer patients were positively correlated with resilience [p < 0.01], while no statistically significant correlations were found for the need for support and satisfaction. The sets of predictors can significantly predict their effects on all types of perceived social support (emotional social support: 9%; perceived instrumental social support: 9%) and all types of received social support (actually received emotional social support: 8%; actually received instrumental social support: 7%; actually received informational social support: 8%). There is a potential mediating role of resilience in relation to sociodemographic factors, clinical characteristics, and the need for support. Conclusion: This study confirms that a strong connection exists between social support and resilience. However, the analysis did not confirm the mediating role of resilience between the sociodemographic and clinical characteristics on the one hand and social support on the other.

Objectives This study aimed to determine the status of training of adult congenital heart disease (ACHD) cardiologists in Europe. Methods A questionnaire was sent to ACHD cardiologists from 34 European countries. Results Representatives from 31 of 34 countries (91%) responded. ACHD cardiology was recognised by the respective ministry of Health in two countries (7%) as a subspecialty. Two countries (7%) have formally recognised ACHD training programmes, 15 (48%) have informal (neither accredited nor certified) training and 14 (45%) have very limited or no programme. Twenty-five countries (81%) described training ACHD doctors ‘on the job’. The median number of ACHD centres per country was 4 (range 0–28), median number of ACHD surgical centres was 3 (0–26) and the median number of ACHD training centres was 2 (range 0–28). An established exit examination in ACHD was conducted in only one country (3%) and formal certification provided by two countries (7%). ACHD cardiologist number versus gross domestic product Pearson correlation coefficient=0.789 (p<0.001). Conclusion Formal or accredited training in ACHD is rare among European countries. Many countries have very limited or no training and resort to ‘train people on the job’. Few countries provide either an exit examination or certification. Efforts to harmonise training and establish standards in exit examination and certification may improve training and consequently promote the alignment of high-quality patient care.

Polymers and polymer composite materials, due to their properties, are becoming increasingly important materials in industry. They are used in a wide range of applications in space and aerospace, aviation, marine and automotive industry, as well as in production of sports equipment, household appliances, medical equipment, etc. They are expected to withstand loads during their lifetime, which requires predicting the reliability of structural elements, i.e. knowledge of material properties. To achieve better properties, polymer materials are reinforced with different percentages of fibre-reinforced materials, including glass fibres. The paper presents the results of experimental determination of the mechanical properties of injection moulded PA6 polymer reinforced with 30% glass fibres, determined by tensile and impact tests.

It is known that gloss has a significant impact on colour measurement. The UV varnish used for surface finishing, spot effects, as well as special effects, such as 3D effects and formation of Braille, has a pronounced gloss effect. In this work, a comparison of the spectrophotometer measurement geometry influence on the colour measurement of an unprinted PVC sample covered with UV varnish was done. UV varnish was applied successively in layers, and patches with different number of varnish layers, from 1 to 12, were formed. Two spectrophotometers with different measurement geometries were used for the measurement: Konica Minolta CM-2600d with d/8 measurement geometry, with spectral reflection included and excluded, and different measurement aperture 3 and 8 mm, and X-Rite eXact with 45/0 measurement geometry. By comparing the measurements, it was estab-lished that there is a significant difference in the measured values between different measuring device geometries on the given samples, and that the number of UV varnish layers has a significant influence on this differenc

This paper presents a new method that enables automatic channel change in case of intense interference on the active channel of a wireless communication point-to-point link. Channel change algorithms on the master and slave side of the communication link are presented, which enable the automatic selection of a new communication channel from a predefined set of available communication channels. By applying this method, it is possible to maintain a stable communication link in case of intense unpredictable interference on the transmitter or receiver side. The method applies to two-way master-slave communication links, regardless of the frequency spectrum and the number of used communication channels.

Abstract Within this paper, the possibility of using advanced LoRa technology in the field of long-range remote control was considered. For testing purposes, a one-way point-to-point LoRa remote control link was implemented based on the LoRa Ra-02 SX1278 transceiver and the corresponding 32-bit Cortex-M3 microcontroller. The remote control application software is developed in the Arduino development environment. The implemented link was tested experimentally to check the range, data transfer speed and link stability. Test results show that LoRa transceiver modules can be used in the field of long-range remote control.
