CPR quality assessment in schoolchildren training
Katia M. G. Oliveira, Maria José C. Carmona, Antonio P. Mansur, Julio Y. Takada, Nino Fijačko, Federico Semeraro, Andrew Lockey, Bernd W. Böttiger, Naomi K. Nakagawa, 2022, original scientific article

Abstract: Whilst CPR training is widely recommended, quality of performance is infrequently explored. We evaluated whether a checklist can be an adequate tool for chest compression quality assessment in schoolchildren, compared with a real-time software. This observational study (March 2019–2020) included 104 schoolchildren with no previous CPR training (11–17 years old, 66 girls, 84 primary schoolchildren, 20 high schoolchildren). Simultaneous evaluations of CPR quality were performed using an observational checklist and real-time software. High-quality CPR was determined as a combination of 70% correct maneuvers in compression rate (100–120/min), depth (5–6 cm), and complete release, using a real-time software and three positive performance in skills using a checklist. We adjusted a multivariate logistic regression model for age, sex, and BMI. We found moderate to high agreement percentages in quality of CPR performance (rate: 68.3%, depth: 79.8%, and complete release: 91.3%) between a checklist and real-time software. Only 38.5% of schoolchildren (~14 years-old, ~54.4 kg, and ~22.1 kg/m2) showed high-quality CPR. High-quality CPR was more often performed by older schoolchildren (OR = 1.43, 95%IC:1.09–1.86), and sex was not an independent factor (OR = 1.26, 95%IC:0.52–3.07). For high-quality CPR in schoolchildren, a checklist showed moderate to high agreement with real-time software. Better performance was associated with age regardless of sex and BMI.

Psychometric properties of the Slovenian version of the Cancer Survivors' Unmet Needs (CaSUN-SL) measure in post-treatment cancer survivors
Špela Miroševič, Polona Selič-Zupančič, Judith B. Prins, Vesna Homar, Zalika Klemenc-Ketiš, 2022, original scientific article

Abstract: Background: As the number of cancer survivors is growing, valid instruments for assessing cancer survivors' needs are required. Thus, the aim of this study was to translate and validate the Cancer Survivors Unmet Needs (CaSUN) scale. Methods: Cancer survivors were recruited from 30 family medicine practices and separated into two samples (sample 1, n = 147; sample 2, n = 148). Factor structure was explored with an exploratory analysis in sample 1 and determined with a confirmatory analysis in sample 2. Psychometric properties were assessed with internal consistency, test-retest reliability and construct validity. Results: A translation and cultural adaptation of the CaSUN scale resulted in 34 items being included in the final version. The factor structure confirmed the five-factors solution of the CaSUN-SL. Cronbach's alpha was 0.94 for the CaSUN-SL and ranged from 0.71-0.88 for specific domains. Test-retest reliability showed moderate-high stability over time. The CaSUN-SL significantly and positively correlated with anxiety (r = 0.49), depression (r = 0.44), health-related quality of life (r = 0.36), and negatively with self-perceived health (r = - 0.36) and resilience (r = - 0.47), which confirms the construct validity. In addition, we found a significant correlation between unmet needs and age (r = - 0.29), gender (r = 0.14), cancer stage (r = 0.20), cancer type (r = 0.19), and time since treatment (r = - 0.20). Conclusions: Results indicate that CaSUN-SL is a valid and reliable measure to assess the Slovenian cancer survivors' unmet, met and total needs and can be used for further prospective studies.

Factors associated with a high level of unmet needs and their prevalence in the breast cancer survivors 1–5 years after post local treatment and (neo)adjuvant chemotherapy during the COVID-19 : a cross-sectional study
Špela Miroševič, Judith B. Prins, Simona Borštnar, Nikola Bešić, Vesna Homar, Polona Selič-Zupančič, Andreja Cirila Škufca Smrdel, Zalika Klemenc-Ketiš, 2022, original scientific article

Abstract: Objective: To assess the prevalence of unmet needs in post-treatment breast cancer survivors and identify sociodemographic, clinical, and psychosocial variables associated with reported unmet needs during the COVID-19 pandemic. Materials and methods: In this cross-sectional study, 430 post-treatment breast cancer survivors, ranging between 1 and 5 years after the procedure, completed the Cancer Survivors’ Unmet Needs (CaSUN) questionnaire from September 2021 and January 2022. The multivariate logistic analysis identified factors associated with at least one reported unmet need in the total CaSUN scale and specific domains. Results: A total of 67% of survivors reported at least one unmet need. The most frequently reported unmet needs were the lack of accessible hospital parking (43%) and recurrence concerns (39.5%). The majority of reported unmet needs relate to comprehensive care (44%), followed by the psychological and emotional support domain (35.3%). Younger age (OR = 0.95, 95% CI = 0.92–0.99; p < 0.001), three or more comorbidities (OR = 0.27, 95% CI = 0.11–0.71, p < 0.01), a lower quality of life (OR = 0.06, 95% CI = 0.01–0.47, p < 0.01) and low resilience (OR = 0.95, 95% CI = 0.93–0.99) were associated with a high level of unmet needs in the multivariate regression model. Results are presented for factors associated with a high level of unmet needs for comprehensive cancer care and psychological and emotional support domain. Conclusion: A high prevalence found in our study could be attributed to the COVID-19 pandemic, where patients may have missed adequate follow-up care, although comparing to studies done in non-pandemic time is difficult. Family physicians should be more attentive toward younger cancer survivors and those with more comorbidities as both characteristics can be easily recognized in the family practice.

Life Cycle Assessment of Pilot-Scale Bio-Refining of Invasive Japanese Knotweed Alien Plant towards Bio-Based Bioactive Compounds
Robert Hren, Katerina Naumoska, Urška Jug, Lidija Čuček, Blaž Likozar, Uroš Novak, Annamaria Vujanović, 2023, original scientific article

Abstract: Japanese knotweed is an invasive alien plant species with characteristic rapid expansion in Europe and North America and resistance to extermination. It displaces autochthonous biodiversity and causes major damage to infrastructure, thus causing global ecological and economic damage. The Japanese knotweed plant is usually eradicated using various chemical, biological, or mechanical techniques, which at a large scale include heavy equipment, usually followed by incineration. Therefore, excavation is preferred to eradication techniques, and as a biomass waste recovery method due to the extraction of high-value biocompounds. This is supported by the fact that the Japanese knotweed possesses various bioactive compounds with beneficial effects on human health. Its rhizome bark extract produces strong and stable antioxidant activity over time, as well as apoptotic, antibacterial, and other beneficial activities. In this work, an environmental impact assessment, including greenhouse gas footprint, acidification, eutrophication, and ecotoxicity for extraction route of the Japanese knotweed rhizome bark, is performed. A comparative case study between the lab-based and proposed pilot-scale production of active added-value extract was evaluated. The results show the pilot-scale production exhibits lower environmental burdens, mainly due to greater electricity requirements for the lab-scale alternative.

Energy indicators and topics in food supply chains' life cycle assessment
Petra Vidergar, Rebeka Kovačič Lukman, 2019, original scientific article

Abstract: Food supply chains have a significant impact on the environment, using large amounts of fossil energy resources and other non-renewable resources. Energy is directly and indirectly needed in all the steps along the food supply chain. This paper explores energy-related indicators in food supply chains and life cycle assessment within sixty-six research papers, gathered from the Web of Science database. Furthermore, a quantitative content analysis was carried out to assess the research trends and future opportunities regarding energy-related topics. The results revealed that a holistic perspective is needed, as energy-related indicators should be included in the use and end-of-life stages, not only in the production processes, and that the inclusion should follow the life cycle assessment methodology. The current research topics are energy issues related to production processes and environmental impacts. Improvements are possible in extending research areas to renewable resources, whole lifecycle perspectives, and socio-economic consequences.

Circular blue bioeconomy for shrimp shell waste valorization: environmental impact assessment : magistrsko delo
Rok Pučnik, 2023, master's thesis

Abstract: The seafood processing industry generates substantial amounts of waste, particularly from the shells of crustaceans. These shells currently hold limited to no value within the food sector, and the current methods of disposal can have negative impact on the natural bioecology. However, these shells still contain valuable compounds such as polymers, minerals, and polyphenols, which could be further utilized. Extracting these compounds using a biorefinery approach, which emphasizes sustainability, could be a viable solution. This master thesis aims to assess the environmental implications, using the Life Cycle Assessment methodology, of a shrimp shell biorefinery process, to produce valuable products, like proteins, chitin, astaxanthin and calcium carbonate. The laboratory-scale biorefinery process was initially upscaled to both pilot and industrial scales, based on equipment design. Also, a comparison between the calculated power demand of units and the power demand of units, derived from Aspen Capital Cost Estimator, was also done. For the laboratory, pilot and industrial sized process, the energy consumption was determined combined with the environmental impact assessment, such as global warming, eutrophication, acidification, ecotoxicity potentials and other. The functional unit was the production of 1 kg of chitin, where the capacity of the laboratory process was linearly scaled up. The evaluation of energy consumption revealed significant disparities among the different scales. Specifically, the upscaled laboratory process exhibited significantly higher energy consumption per kg of chitin (5,882.1 kWh) in comparison to the pilot (62.3 kWh) and industrial (21.1 kWh) scales. This outcome underscores the inadequacies of employing a linear scale-up in environmental analysis. Notably, centrifugation dominated electrical energy consumption at the laboratory-scale and industrial-scale, while refrigeration took over this role at the pilot-scale process. Related to impact assessment it was found that both pilot- and industrial-scale processes demonstrated lower overall environmental impacts, compared to the laboratory-scale process in all evaluated categories. Acidification, photochemical oxidation, eutrophication and global warming potential exhibited the most significant variations, with reductions ranging up to 97 %, while ozone layer depletion displayed only a 17 % decrease. Importantly, all three scales also exhibited some positive effects (unburdening the environment) due to the use of shrimp shell materials, with particularly noticeable improvements in the category of terrestrial ecotoxicity.

Sustainable development in transport and logistics
Vasja Omahne, 2021, master's thesis

Abstract: The support for an ongoing global pursuit of sustainable development, consumer awareness about sustainability, and regulations have affected the transport and logistics sector due to the fact that it presents ample environmental, social and economic challenges. The transport sector contributes globally to about 14% of greenhouse gas emissions, and around one third of the European Union's emissions, yet also represents an important economic sector, employing around 10 million individuals, thus requiring an in-depth discussion, especially regarding environmental impact. Due to increasing global concern for the environment, companies and policymakers are facing pressure to reduce the environmental impact related to transport and logistics activities and make them more sustainable. Before choosing a best practice for improvement, especially regarding the environmental perspective, a thorough analysis regarding the environmental impact has to be carried out based on reliable data and methodology. For such purposes, the life cycle assessment (LCA) defined by standards ISO 14040 and 14044 is commonly used. While the LCA focuses only on the environmental perspective, sustainability is represented by three dimensions, which are environmental, economic and social and those are interlinked, which presents a challenge, as each dimension has a major impact on every stage of the life cycle of a product, process or service. Thus there is a need to evaluate all three perspectives of sustainability in order to make transport and logistics processes more sustainable. Another option to make transport and logistics processes more sustainable and to achieve sustainable development is through education. Thus, it is important to integrate sustainability-oriented topics in logistics programs and courses, and consequently educate future logisticians about sustainability. Considering environmental burdens and sustainable development in transport and logistics, we explored LCA regarding its use in transport and logistics and studied the integration of sustainability into logistics education in EU, as it is important to educate future logistics managers and decision makers to gain sufficient knowledge on the importance of sustainability. Also, as logistics processes pose several environmental challenges and impacts, social and economic impacts are the ones that are frequently overlooked. Thus we additionally focused on performing an applicable comprehensive sustainability evaluation of a monkey toy and evaluated its environmental (through LCA), social (through SLCA) and economic (through LCC) impacts through the life cycle. At the same time, we explored options to enhance the present CE concept in the monkey toy company. Exploring the use of LCA in transport and logistics, we focused on the state-of-the-art of transport-related life cycle assessment studies, as they are important for the decision-making processes. Our research of LCA & transport studies was framed around the requirements of the International Organization for Standardization. A specific focus was given to the quality of life cycle assessment phases, comprehending goal and scope, inventory, life cycle impact assessment, and interpretation. Thirty-four research and review papers were studied, sourced from the Web of Science database. Studying the monkey toy, we firstly assessed the environmental impacts of the toy through LCA and additionally combined it with SLCA and LCC to evaluate the toy's sustainability comprehensively. Based on the results of the sustainability evaluation, we gained an insight into environmental, economic and social hotspots that the monkey represents. We then presented a possible enhancement of the CE concept. Lastly, focusing on logistics education, we analyzed and elaborated upon an integration of sustainability topics at higher education programs in logistics and their curricula for bachelor and master degrees at universities across Europe.
