Aim To determine risk factors for deep vein thrombosis (DVT) in hospitalized patients in a 10-year follow-up. Methods In this observational study data were collected from the disease history of patients admitted to the Department of Angiology of the Clinical Centre University of Sarajevo in the period of 10 years (2008-2017). Of 6246 hospitalized patients, 1154 were with established diagnosis of DVT and included in the study as a basic inclusion criterion. Results Provoked venous thromboembolism was recorded in 45.75% of hospitalized patients. In 54.25% cases DVT was classified as idiopathic; in the remaining cases with DVT external risk factors were identified. Every fourth patient had a history of malignancy, and this risk factor was significantly more common among women and younger patients. Cancer of female reproductive organs, colon, lung, breast and prostate cancer were most common. One of 10 women had DVT during pregnancy or postpartum period. Out of the total number, 10.9% patients had DVT after surgery, 2.3% after injury. DVT was found in 1.6% of drug addicts. Rethrombosis was diagnosed in 5.2% patients within a year, while 9.2 % patients had rethrombosis within five years. Conclusion Provoked venous thromboembolism is an entity that can be prevented. Malignancy and surgical treatment are the most common risk factors and these patients should be treated with special care. The creation of a register of patients with venous thromboembolism in Bosnia and Herzegovina would enable the development of a preventive strategy in the groups of patients at risk.

Modulation signal classification (MSC) is an indispensable technique to make the possible applications of non-cooperative communications. Currently, convolutional neural network (CNN) based MSC techniques can achieve an outstanding performance at a fixed noise regime. However, they are hard to generalize to all of noise scenarios. Because these conventional methods are trained on specific signal samples with fixed SNR and they only perform well under corresponding noise condition. Unlike the conventional methods, in this paper, we propose a robust CNN based generalized MSC (GMSC) method with powerful generality capability. This capability stems from the mixed dataset, containing in-phase and quadrature (IQ) samples under various SNR regimes. Experimental results show that the proposed method is robust under varying noise conditions, while merely losing a slight performance with comparing with conventional methods.

Introduction: Laparoscopic cholecystectomy is now considered the procedure of choice that achieves a shorter recovery period after the surgery and reduction in the cost of treatment. Aim: The aim of the study is to prove which method: early or delayed laparoscopic cholecystectomy is the method of choice in the treatment of acute cholecystitis by examining: duration of hospitalization, conversion rate, duration of surgery, postoperative complications, and total cost. Methods: The study was conducted at the University Clinical Center of Republika Srpska as a retrospective-prospective study from May 1st 2013 until December 31st 2019. Patients diagnosed with acute cholecystitis were divided into two groups: Patients designated for early laparoscopic cholecystectomy within 72 hours of admission (group A–42 patients), Patients designated for initial conservative treatment followed by a delayed interval of 6-12 weeks until surgery (group B-42 patients). Results: In both groups, there were statistically significantly more female respondents. The results showed that the average cost of treatment in the early treated group was statistically significantly lower than the cost of treatment in the delayed treatment group. The patients in the early group had shorter hospitalization times (an average of 2.8 days and 5.6 days in the delayed group of patients), a smaller percentage of conversions (4.8% in the early and 16.7 in the delayed group of patients), the total cost of in the early group it was 1300.83 KM, while in the delayed group it was 1645.43 KM. Conclusion: Early laparoscopic cholecystectomy is a method to be preferred in surgical treatment.

Aim To determine differences in quantitative traits of digital dermatoglyphics between breast cancer women and the women in the control group (healthy women). Methods This case-control study included digital dermatoglyphics of 50 patients with confirmed breast cancer diagnosis compared with 50 healthy examinees with the absence of familial history of any type of cancer. Collecting samples was performed among Bosnian-Herzegovinian population by Printake method. The comparison of the mean values between the examined groups was made by the Student's t-test and Mann-Whitney U test. Results The results showed that, with regards to the pattern intensity, no statistically significant difference was detected between the two examined groups (p>0.05).The absence of any significant difference in the number of papillary ridges on an individual finger between the breast cancer patients and the control group was found (p>0.05), although the total number of papillary ridges on all ten fingers had somewhat lower values in the examined group. Conclusion This research confirms the existence of genetic predisposition for breast cancer development, emphasizing the relevance of hereditary factors in the ethiopathogenesis of this disease. The quantitative traits of digital dermatoglyphics were not a reliable and predictive tool for detecting a potential risk for breast cancer in small populations.

Aim To present combined measles cases data and phylogenetic analysis of the virus circulated in 2018 in the Federation of Bosnia and Herzegovina (FB&H, the entity of Bosnia and Herzegovina), in order to analyse endemic transmission patterns of circulating strains and its implications for elimination efforts. Methods The data were derived from epidemiological case investigations and laboratory diagnoses based on serology, molecular detection and genotyping of the measles virus. Results During 2018 16 measles cases were reported in FB&H, of which five were classified as laboratory confirmed cases, one was an epidemiologically linked case and 10 were clinically compatible cases. Among them 12 (75.00%) cases were unvaccinated or had unknown vaccination status. The most affected population was up to 14 years of age (13/16; 81.25%). None of the cases was fully vaccinated. Viruses of other genetic lineages had been introduced in FB&H in the recent period. Two virus lineages of genotype B3 were identified. Phylogenetic analysis indicated the presence of a unique sequence of measles B3 virus in FB&H (Sarajevo). Conclusion Further strengthening of measles surveillance system and renewed efforts to increase vaccination levels are necessary to prevent disease and for elimination setting.

Aim To determine stereological structural parameters of the parenchymal part of the placenta, placental weight and volume of adolescent pregnant women and their correlation with newborns' birth weight. Methods This prospective study was conducted on a total of 60 human placentas of term pregnancy, divided into two groups according to the age of pregnant women. Experimental group consisted of 30 placentas of pregnant women aged 13-19 years. Control group consisted of 30 placentas of pregnant women aged 20-35 years. Stereological analysis was performed. Results Volumetric density of terminal villi of adolescent placentas was significantly higher than the one of control group (p <0.0001). The volumetric density of fibrinoid of adolescent placentas was significantly lower than of the control group (p <0.0001). Total volume of terminal villi of adolescent placentas was significantly higher than of the control group (p<0.0001). The total volume of fibrinoid of adolescent placentas was significantly lower than of the control group (p<0.0001). Newborns of adolescent pregnancies had in average lower birth weight of 439.01 g compared to the newborns of the control group (p <0.00001). Conclusion Adolescent pregnancy affects placental structure, weight and volume. Newborns of adolescent pregnancy have optimal body weight.

Aim To compare the quality of the conditions for endotracheal intubation and muscle relaxation between rocuronium bromide and vecuronium bromide using the ''timing principle'' method for induction in anaesthesia. The "timing principle" includes the administration of muscle relaxants before the hypnotic agent during induction in anaesthesia. Method Sixty patients who had undergone elective surgery were randomly allocated into two equal groups using muscle relaxants: rocuronium (group R) and vecuronium (group V). The intubation conditions were assessed using Cooper's scoring system, based on jaw relaxation, vocal cords position and response to intubation. The quality of muscle relaxation was evaluated by recording the time of clinical weakness, a count of ''train of four'' (TOF) twitches at intubation, the time of loss TOF response and duration of direct laryngoscopy. Results The intubation conditions were excellent in 100% of patients in the group R versus excellent in 80% and good in 20% of patients in the group V (p<0.05). The time of clinical weakness was statistically significantly shorter in the group R than in the group V (p<0.000). The time of loss of TOF response was statistically significantly shorter in the group R (p<0.000). The absence of TOF twitches (the level of muscle relaxation of 100%) at intubation recorded in 25 (83.3%) patients in the group R versus five (16.7%) patients in the group V (p<0.000). Duration of direct laryngoscopy did not significantly differ between the groups. Conclusion Rocuronium bromide provides better intubation conditions and greater quality of muscle relaxation than vecuronium bromide using ''timing principle'' technique.

A key mutational process in cancer is structural variation, in which rearrangements delete, amplify or reorder genomic segments that range in size from kilobases to whole chromosomes1–7. Here we develop methods to group, classify and describe somatic structural variants, using data from the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA), which aggregated whole-genome sequencing data from 2,658 cancers across 38 tumour types8. Sixteen signatures of structural variation emerged. Deletions have a multimodal size distribution, assort unevenly across tumour types and patients, are enriched in late-replicating regions and correlate with inversions. Tandem duplications also have a multimodal size distribution, but are enriched in early-replicating regions—as are unbalanced translocations. Replication-based mechanisms of rearrangement generate varied chromosomal structures with low-level copy-number gains and frequent inverted rearrangements. One prominent structure consists of 2–7 templates copied from distinct regions of the genome strung together within one locus. Such cycles of templated insertions correlate with tandem duplications, and—in liver cancer—frequently activate the telomerase gene TERT. A wide variety of rearrangement processes are active in cancer, which generate complex configurations of the genome upon which selection can act. Whole-genome sequencing data from more than 2,500 cancers of 38 tumour types reveal 16 signatures that can be used to classify somatic structural variants, highlighting the diversity of genomic rearrangements in cancer.

Advances in cloud computing make cloud services as an appealing solution for enabling services flexibility and availability on demand to accommodate users' needs. The terms and the guarantees of service provision are negotiated and then stated in a Service Level Agreement (SLA). To facilitate a wider acceptance of such services, beside the standard properties, security has to be taken into consideration as well. One way to facilitate this is to provide a corresponding security assurance case. For that purpose, in this work we propose to split the security service assessment between an independent third party and a service user, where the former assess a security assurance case and the latter negotiates particular security solutions implemented for a service. For the systematic part of the security process that is independently assessed, in this paper we focus on the formal realizability check of service constraints expressed within an SLA. To enable this, we formalize the check at both service design-, and run-time, needed due to frequent updates required to maintain an agreed security level. The formalization is tailored for the SLAC language specifically, which is extended to cover a proposed set of security objectives. Moreover, we use an example of an SLA expressed in terms of SLAC language, which includes security guarantees to illustrate the approach.
