Among Enterococcus spp, only the virulence gene harboring strains of Enterococcus faecalis and E. faecium are associated with human infections, including urinary tract infections (UTI), pelvic, blood, intraabdominal, and skin and soft tissue infections (SSTI). Over the past decades, enterococcal antimicrobial resistance has escalated in many regions of the world, leading to ominous outcomes. The rising incidence of Healthcare-Associated Infections (HCAIs) secondary to Vancomycin-resistant strain (VRE) resulted in high morbidity and mortality, as well as substantial challenges in control, prevention, and management). The aim of this study is to examine the antimicrobial resistance of E. faecalis and E. faecium species in different human samples. The study included 184 clinical samples over a period of 6 months. E. faecalis was identified in 95.65% and E. faecium in 4.35% of cases. E. faecalis isolates showed resistance to gentamicin in 40.9% of cases and to ampicillin in 1.7% of cases. Resistance to nitrofurantoin and ciprofloxacin was observed in 6.1% and 35.7% of E. faecalis isolates. VRE was isolated in 1.1% of E. faecalis isolates tested for this antibiotic. Resistance of E. faecium isolates to ampicillin and gentamicin was observed in 87.5% of cases in both antibiotics. All urinary isolates of E. faecium were resistant to ciprofloxacin. All E. faecium isolates were sensitive to vancomycin. Based on the results of our study, the growing importance of Enterococcus spp. as a causative agent of hospital infections and infections in the general population, and its antimicrobial resistance to various drugs were observed.

In the H2020 European project ASHVIN “Assistants for Healthy, Safe, and Productive Virtual Construction Design, Operation & Maintenance using a Digital Twin”, a set of Key Performance Indicators (KPIs) and Performance Indicators (PIs) to plan and control productive, resource efficient, and safe maintenance are being developed for transport infrastructure. This paper is presenting PIs and KPIs for the assessment and monitoring of the following aspects: Productivity, Resource Efficiency, Cost, Health & Safety during the operational life cycle stage, which is mainly focusing on the inspection and maintenance planning. Quantifiable and measurable PIs and KPIs are proposed and applied on two demonstration projects, highway bridge in Spain and airport runway in Croatia, as part of transportation infrastructure. Proposed PIs and KPIs are integrated into digital twins of the analyzed assets and into decision making tools for risk based maintenance planning. This paper presents the overview of the proposed digital PIs and KPIs applied on two demonstration projects and the integration into decision support tools for efficient and sustainable maintenance planning.

Vehicular ad hoc network (VANETs) improves road safety and efficiency by organizing vehicles and infrastructure to provide a platform for application deployment. The availability of vehicles and infrastructure is critical to the operation of applications. Accurate failure detector (FD) has been one of the fundamental components for maintaining high availability in VANETs. However, it is hard to find the vehicle failure accurately and timely due to the dynamic nature of VANETs caused by the high mobility of vehicles and communications link failures. Therefore, it is important to achieve an accurate FD which can cope with the high mobility of VANETs. In this paper, we propose a dead reckoning based FD, called DR-FD. It can predict the mobility of vehicle accurately and avoid the impact of link failures on the detection results by the cooperation between vehicles. Experimental results are provided to confirm that the proposed DR-FD method can achieve at most 20% reduction in detection time, 30% improvement in mistake rate and 20% improvement in overhead.

Background: In December of 2019, SARS-CoV-2, a new type of coronavirus, appeared, and it turned into an international epidemic. The consequences of the pandemic, especially the isolation measures, fear of infection and bad economic trends, as a result of the crisis, threaten people's basic psychological needs. Objective: The objective of this research was to assess the impact of the COVID-19 pandemic on mental health and perceived social support of persons with disabilities in Bosnia and Herzegovina. Methods: The research included a total sample of 232 respondents with different types of disabilities. The Symptom Checklist (SCL-90) was used to verify the research objective, which assessed three dimensions: somatization, depression and anxiety. Also, in order to verify the research objective, the Multidimensional Scale of Perceived Social Support was applied, which consists of 12 statements that measure the perceived social support of family, friends and other people. The research data was processed with descriptive and inferential statistics. The basic statistical parameters were calculated, while the t-test was used for an independent sample of respondents to verify the set objective. Results: The results of the research showed that persons with disabilities, who were infected with the SARS-Cov-2 virus, had a significantly higher level of somatization, anxiety and depression compared to those who were not infected with the virus. The results in relation to social support did not prove to be statistically significant. Conclusion: The obtained results lead to the conclusion that, in the future, interventions by experts of various profiles must be planned to preserve the mental health of persons with disabilities, which is why it is important to invest in the emotional, psychological, social, physical and spiritual well-being of the individual.

Robots are commonly envisioned as assisting older adults in physical tasks or providing companionship. But there has been less focus on helping older adults achieve more intangible, but equally important, aspects of wellness, such as a feeling of purpose and meaning in life. Here, we share our experiences working and learning together with older adults on developing a robot that can support their achievement of ikigai---meaning or purpose in life.

Abstract It is known that aquatic macrophytes are an important part of freshwater ecosystems, and that they play a different role in their structure and functioning. Their presence and distribution depends on water temperature and transparency, nutrient content, conductivity, pH, chemical composition and water circulation. Therefore, the goal of our research was to determine the influence and interrelationship of physicochemical parameters of water on the content of photosynthetic pigments in aquatic macrophytes of Lake Necik, in the Ramsar area of Bardača (Republic of Srpska). Content of total chlorophyll (a + b) during the growing season (June–October) ranged from 0.231 to 1.145 mg g−1 FW in Phragmites communis Trin. ex Steud., from 0.061 to 0.541 mg g−1 FW in Salvinia natans L. (All.), from 0.063 to 0.626 mg g−1 FW in Utricularia vulgaris L. and from 0.063 to 0.443 mg g−1 FW in Ceratophyllum demersum L. Research has shown that floating and submerged macrophytes have a lower ratio of chlorophyll a/b compared to emergent hydrophytes, which is most likely the result of stress caused by increased light intensity and temperature. Seasonal variations in the content of photosynthetic pigments indicated that the species Phragmites communis proved to be more tolerant to the stress caused by the influence of various abiotic factors, while Salvinia natans proved to be more sensitive. Spearmon’s correlation coefficient of the physicochemical parameters of water and the concentration of photosynthetic pigments of macrophytes showed a significant influence of certain abiotic factors (temperature, transparency and nutrients) on the content of pigments in the leaves of Phragmites communis, Salvinia natans, Utricularia vulgaris and Ceratophyllum demersum L.

Advancements in neurosurgical visualization have been made possible by the introduction of the operating microscope (OM) and the emergence of exoscopic technology (EX). Both OMs and EXs provide enhanced magnification and illumination, but they come with their own set of advantages and disadvantages. OMs provide high-quality magnification and illumination and have been used successfully in a variety of surgical procedures. They can be customized to fit the specific needs of the surgeon and are a well-established technology. However, they can be bulky, expensive, and cause discomfort during extended procedures. EXs provide high-definition magnification and illumination, improved depth perception and ergonomics, and can be cost-effective. They can be customized to fit the specific needs of the surgeon and can be made using locally available materials, reducing the need for expensive imports. However, they may require adjustment and have a learning curve for surgeons who are used to operating with OMs. Additionally, they may have limited availability in some healthcare settings. The choice between OMs and EXs will depend on the specific needs of the surgeon and the healthcare setting. The integration of 3D EX systems has revolutionized neurosurgery, offering improved depth perception and ergonomics. EX's cost-effectiveness addresses accessibility concerns, making it an attractive alternative, particularly for low and middle-income healthcare settings. The exoscope seems to be a safe alternative compared to an operative microscope for the most common brain and spinal procedures. The exoscope may help expand access to neurosurgical care and training worldwide. In conclusion, both technologies have their own set of advantages and disadvantages, and the choice between them will depend on the specific needs of the surgeon and the healthcare setting.

Objective: The main objective of this research is to determine the prevalence and characteristics of neurological manifestations in hospitalized patients with SARS-CoV-2 infection. Methods: A cross-sectional study was conducted. 572 hospitalized patients at the COVID Department of Pulmonology of the Mostar University Clinical Hospital in the six-month period from October 31, 2020, to April 30, 2021, were included. We analyzed the incidence of neurological manifestations and the influence of comorbidities and metabolic syndrome on stroke incidence in COVID-19 patients. We analyzed hospital length of stay and mortality in patients with and without neurological manifestations. The research was conducted with respect to all the determinants of the Helsinki Declaration. Results: 572 patients, 351 men (61.4%), and 221 women (38.6%) were included. A fatal outcome was present in a quarter of patients (25.3%). Neurological manifestations were found in 163 patients (28.5%). Myalgia was the most common (16.1%). The following were reported: headache (9.6%), loss of taste (7.34%), loss of smell (6.8%), and vertigo (2.5%). There was a significant difference regarding loss of smell between males and females (p=0.04). The cerebrovascular incident was present in 2.97% of patients and was more frequent in the group of patients with metabolic syndrome. Patients with neurological manifestations had a longer hospital stay, but it was not statistically significant (p=0.9319). The presence of neurological manifestations in general did not influence the mortality rate. Conclusion: Patients with SARS-CoV-2 infection can present with neurologic findings such as myalgia, headache, loss of smell or taste, vertigo, as well as cerebrovascular incidents. Patients with neurological manifestations had longer hospital stays, but the presence of neurological manifestations in general did not influence the mortality rate.

Abstract The aim of this study was to examine the seroprevalence of Leptospira spp. in dogs and red foxes in the entity of the Republic of Srpska, Bosnia and Herzegovina, after heavy rainfall and floods in 2014 and for the two years thereafter. The seroepidemiological study involved testing serum samples from dogs (n = 98) and foxes (n = 112) using MAT (microscopic agglutination test). Antibodies to at least one Leptospira spp. serovar were found in 52.04% of the tested dogs. The dog seroprevalence in 2014 (81.25%) was significantly higher than in 2015 (51.42% p <0.0001) and 2016 (22.5% p<0.05). The highest seroprevalences were for serovars Australis (76.47%), Bratislava (70.58%), Sejroe (66.67%) and Autumnalis (45.09%). Antibodies to at least one Leptospira spp. serovar were detected in 34.82% of the examined red foxes. In 2015, the fox seroprevalence was significantly higher (52.94%) than in 2016 (6.82%) (p <0.0001). The highest seroprevalences were for serovars Sejroe (64.10%), Bratislava (48.72%), Australis (43.59%) and Bataviae (25.64%). The high seroprevalence of Leptospira spp. in dogs and foxes determined during this study indicates the importance of these carnivores in maintaining leptospirosis in the study area, and the potential risk of infection for humans and other animal species that come into contact with these canids. The results obtained indicate that heavy rainfall and intense floods can result in increased Leptospira spp. infection in these canids.
