Bolesnici s amiotrofi čnom lateralnom sklerozom zahtijevaju kompleksnu skrb i multidisciplinarni pristup, koji je individualno
prilagođen potrebama bolesnika. Ciljevi neurorehabilitacije moraju biti ...prilagođeni stadiju bolesti. U ranom stadiju bolesti potrebno je započeti s fi zikalnom terapijom radi očuvanja i optimiziranja motoričke i respiratorne funkcije. Već u ovom stadiju potrebno je angažirati obitelj bolesnika u provođenju određenih aktivnosti i upoznati ih s prirodom bolesti. U kasnijem tijeku bolesti potrebno je provoditi fi zikalnu terapiju kako bi se spriječile respiratorne komplikacije i kontrakture, te se primijenila adekvatna ortopedska pomagala. Nastupom dizartrije nastaje potreba za evaluacijom akta gutanja i respiratorne funkcije. U početku se primjenjuju određeni manevri a potom nazogastrična sonda i perkutana gastrostoma. Primjenom neinvazivne mehaničke ventilacije i respiratorne fizioterapije može se odgoditi potrebu za traheostomom i invazivnom
mehaničkom ventilacijom. Uloga multidisciplinarnog pristupa je pružiti optimalnu medicinsku skrb, olakšati komunikaciju a time poboljšati kvalitetu skrbi i života.

This paper considers the problem of tracking the players in handball videos using a single video source. Tracking of handball players in the video is a difficult task as they can frequently leave and ...re-enter the camera field of view, often change directions quickly and occlude each other. Players wear similar team uniforms, play indoor under artificial illumination, with the background than can vary significantly as the handball court is often painted in various colors. The continually improving accuracy of CNN-based object detectors makes tracking-by-detection methods an attractive choice for tracking players in sports videos as they can perform online and with low computational requirements on top of object detection. Here we consider the use of three tracking-by-detection methods in conjunction with the YOLO object detector, namely the standard Hungarian assignment algorithm, the Simple Online, and Real-time Tracking (SORT) algorithm that adds a motion model, and its extension Deep SORT. The methods are tested on a custom dataset of handball video scenes.
Primary carcinoid tumors of the ovary account for 5% of ovarian teratomas. They are frequently components of mature cystic teratomas or, less commonly, mucinous cystadenomas. Most tumors are seen in ...peri- or postmenopausal women with symptoms of enlarging mass, or are incidental findings. Microscopically, there are four major variants of ovarian teratomas of carcinoid type: insular, trabecular, strumal and mucinous. One-third of patients with the insular type of carcinoids have symptoms of the carcinoid syndrome. Strumal carcinoid is an unusual form of ovarian teratoma composed of an intimate admixture of thyroid and carcinoid tissues that vary in their relative proportions. Two patients with ovarian tumors showing typical morphology of primary ovarian strumal carcinoid are described.

The use of drones in search and rescue operations has become standard almost everywhere in the world. A special challenge in the search and rescue operation is the automatic detection of persons in ...different terrains, in different situations and body positions, in different weather conditions, and from different shooting heights during a drone flight. This paper investigates the accuracy of people detection in drone images on existing VisDrone, Okutama - Action datasets, and on a custom SARD image dataset built to simulate search and rescue scenes. A Faster R-CNN with FPN as the backbone, pre-trained on the COCO data set, was used as a detector. The person detector is additionally trained on the SARD data set containing 1,981 images and on the subset of the VisDrone set. After transfer learning, a significant improvement in the detection results of persons in the images taken by the drone was achieved concerning mAP and precision and recall.
The aim of the study was to investigate the effects of chorioamnionitis on mortality and early onset neonatal sepsis (EONS) and bronchopulmonary dysplasia (BPD) in preterm neonates with birth weight ...< or = 1,500 g. The study included 395 preterm infants born at the Zagreb Clinical Hospital Center, from January 2001 to December 2005. All the placentas from preterm deliveries were sent for pathological examination. The patients were categorized into two groups: one including patients with chorioamnionitis at placental histology (47%) and the other control group without chorioamnionitis (53%). Neonates were distributed into 3 groups according to gestational age: the first group with 132 (33%) infants born at < or = 28 weeks of gestation, the second with 202 (52%) infant born from 29 to 32 weeks of gestation and the third with 61 (15%) infants born at > or = 33 weeks gestation. Chorioamnionitis was diagnosed significantly more often in the first gestational age group (91/132-69% of infants, chi2 = 51.307, p < 0.05). The outcome was lethal in 67/395 (17%) patients; 55% of them had chorioamnionitis (chi2 = 2.421, p > 0.05). Lethal outcome ensued in 54/132 (41%) infants from the first gestational age group; 30/54 (55%) were born from pregnancies complicated by chorioamnionitis. In comparison with the control group, mortality was significantly higher in the group of premature infants with gestation < or = 28 weeks whose placentas showed chorioamnionitis (chi2 = 7.645, p < 0.01). EONS was probable or confirmed in 100/395 (25%) infants; in 66/100 (66%) infants pregnancy was complicated by chorioamnionitis (chi2 = 22.396, p < 0.01). BPD developed in 25/395 (6%) infants; in 12/25 (48%) infants placentas showed chorioamnionitis (chi2 = 0.022, p > 0.05). In conclusion, premature neonates from pregnancies complicated by chorioamnionitis are more often born at < or = 28 weeks of gestation. Chorioamnionitis in neonates whose gestation is < or = 28 weeks leads to a significantly higher rate of mortality than in neonates with a longer gestation period. A greater incidence of EONS was proven in the group of infants with chorioamnionitis. The difference between the incidence of BPD in preterm infants born from pregnancies complicated by chorioamnionitis and the control group was not significant.
By using drones in search and rescue (SAR) missions, missing person detection is possible during or after the flight by analyzing the recorded material. However, person localization is equally ...important so that rescuers can approach the person in the shortest possible time. We propose a raycast method to determine both a person's location and the distance from the drone, using a sequence of monocular drone images. The proposed method has been tested in silico, using a custom-made procedural simulator, calibrated for windless and windy conditions. We concluded that multiple raycasting solves unreliable telemetry problems and that there is an optimal number of required iterations, depending on the telemetry noise of a specific drone.
Oil is one of the most important strategic raw materials globally, which implies that all major events in the oil market and the oil industry impact the state of the global economy. Given that the ...oil industry, events in it can be viewed as factors that affect the economy, it is important to understand the characteristics of the industry and the impact of management decisions of the company on the industry itself. The subject of this paper is a review of the oil industry through an overview of the application of the regularity of economic theory in managerial decision-making. Secondary data were used to write the paper, referring to books, textbooks, scientific articles related to the field of management economics, and the official annual reports of INA d.d. were used to perform the analysis. In addition to the above, relevant Internet sources and literature in the field of financial statement analysis and crisis management were used. The scientific research methods used in this paper relate to the method of description, the method of analysis and synthesis, the inductive and deductive methods, and the method of comparison. This paper aims to get acquainted with the elements of management economics within the oil industry and use the theory of managerial economics to identify factors that contribute to the improvement of business in the observed industry. An analysis of the oil industry in the Republic of Croatia was conducted and the business operations of INA d.d.
We report two new cases of cystic fibroepithelioma of Pinkus together with immunohistochemical features and analyze the presence of cystic changes in a series of 16 classical fibroepitheliomas of ...Pinkus. Our findings show that the formation of cystic spaces is most probably caused by ischemic degeneration of stromal fenestrations, rather than by central tumor cell necrosis. This finding is supported by lack of CD34 positive blood vessels in edematous and hyalinized stromal fenestrations undergoing transformation into cystic spaces, as opposed to the uninvolved stromal fenestrations. Therefore, it is probably more accurate to refer to this process as pseudocystic stromal degeneration rather than true cyst formation. Also, two out of 16 classical Pinkus fibroepitheliomas exhibited focal pseudocystic changes in 50% and 10% of the tumor, respectively, demonstrating that this degenerative process can be found, rarely and focally, in classical cases as well.
Although speech, in computer-synthesized form, became an integral part of computer games as early as 1978, its application, especially in the location-based computer game genre, has been barely ...explored. In this paper, computer games and the role of sound and speech in them are discussed, focusing on location-based games and voice games. A brief introduction to speech technologies relevant in the context of applications in computer games is given, and current research relating to the analysis of computer games created in the period from 1978 to 2018, which uses speech, is presented. To determine the possibility of using speech in location-based computer games, it is necessary to analyze the current practice of using speech technology in computer games in general and identify innovations that positively or negatively affect the overall rating of a particular game, recognizing which of these features apply to the development of location-based games, respecting their specifics. For this purpose, a sample of 50 games was formed that included games analyzed in previous research, supplemented with games found on the Internet by the criterion of using any form of speech specified in the reviews and documentation of individual games. The conclusion answers the question of whether it makes sense, given the specifics of the genre and the current state of technology, to introduce voice technologies into location-based games and what are the prerequisites.
