Lipoprotein(a) as a risk factor in a cohort of hospitalised cardiovascular patients : A retrospective clinical routine data analysis
David Šuran, Tadej Završnik, Peter Kokol, Marko Kokol, Andreja Sinkovič, Franjo Naji, Jernej Završnik, Helena Blažun Vošner, Vojko Kanič, 2023, original scientific article

Abstract: Lipoprotein(a) (Lp(a)) is a well-recognised risk factor for ischemic heart disease (IHD) and calcific aortic valve stenosis (AVS). Methods: A retrospective observational study of Lp(a) levels (mg/dL) in patients hospitalised for cardiovascular diseases (CVD) in our clinical routine was performed. The Lp(a)-associated risk of hospitalisation for IHD, AVS, and concomitant IHD/AVS versus other non-ischemic CVDs (oCVD group) was assessed by means of logistic regression. Results: In total of 11,767 adult patients, the association with Lp(a) was strongest in the IHD/AVS group (eβ = 1.010, p < 0.001), followed by the IHD (eβ = 1.008, p < 0.001) and AVS group (eβ = 1.004, p < 0.001). With increasing Lp(a) levels, the risk of IHD hospitalisation was higher compared with oCVD in women across all ages and in men aged ≤75 years. The risk of AVS hospitalisation was higher only in women aged ≤75 years (eβ = 1.010 in age < 60 years, eβ = 1.005 in age 60–75 years, p < 0.05). Conclusions: The Lp(a)-associated risk was highest for concomitant IHD/AVS hospitalisations. The differential impact of sex and age was most pronounced in the AVS group with an increased risk only in women aged ≤75 years.

The relationship between leadership in BPM and company profitability
Dušan Gošnik, Maja Meško, Igor Stubelj, 2023, original scientific article

Abstract: This paper studies the relationship between leadership as an activity of business process management (BPM) and company performance. Business process data about leadership and business processes in SMEs were collected via questionnaires on the population of 3007 SMEs in Slovenia. Aspects of leadership such as the involvement of employees, middle management, customers and suppliers were studied. The financial data of the SMEs of the sample were obtained from publicly available financial statements to assess relative residual income profitability ROEr and ROEa. Data analysis was performed using Bartlett’s, Kaiser–Maier–Olkin and nonparametric Mann–Whitney U tests. We confirmed a positive relationship between employee involvement in leadership as an activity of BPM and company profitability. It was proved that companies that involve employees and middle management in improving core business processes to a greater degree are more profitable. Intense involvement of employees in changes in core business processes results in higher company profitability, which has been detected by the higher risk-adjusted profitability measure ROEa. Companies that involve middle management to a greater degree by leading employees based on their interests are more profitable. The results are important for managers as decision-makers and other company stakeholders, especially those responsible for business process improvements. Theoretical and practical implications and further research possibilities are discussed.
Keywords: management, leadership, BPM, risk-adjusted profitability measures, SME, performance

Don't leave your heart at work : profiles of work-life interference and cardiometabolic risk
Katja Kerman, Sara Tement, Christian Korunka, 2021, original scientific article

Abstract: The present study adopts an exploratory, person-oriented approach to investigate possible patterns of work-life interference. We examine work–life interference from a cognitive (i.e., thinking about work), behavioral (i.e., engaging in work-related behavior), and performance perspective (i.e., reduced functionality in private life, or work–life conflict) in order to identify profiles of employees that could potentially remain uncovered with variable-oriented research. Furthermore, as work–life interference relates to well-being and health, we were interested in exploring possible differences between profiles in emotional exhaustion, cardiometabolic risk, and health-related behavior. Self-report data on work–life interference and well-being, as well as objective health data, were collected from a heterogeneous sample of 289 employees. Four profiles with different patterns of work–life interference were identified. Out of the four profiles, two profiles reported moderate and high work–life interference (the Moderate Interference and High Interference profiles). The other two profiles revealed distinct combinations of moderate and low performance and behavioral interference (the Low Performance Interference and Low Behavioral Interference profiles). The High Interference and Low Behavioral Interference profiles were identified as risk groups in terms of cardiometabolic health, while the Low Performance Interference and Moderate Interference profiles showed low to no risk. Regarding work-related well-being, the High Interference profile showed the highest risk of emotional exhaustion.
Keywords: work-life interference, person-oriented approach, latent profile analysis, well-being, cardiometabolic risk

A Framework for adopting a sustainable reverse logistics service quality for reverse logistics service providers : a systematic literature review
Ahmed Dabees, Mahmoud Barakat, Sahar Sobhy El Barky, Andrej Lisec, 2023, review article

Abstract: Reverse logistics has become a competitive need for sustainability. Lack of resources to apply reverse logistics solutions has severely impacted many supply chains’ costs and customer service, making it impossible to meet the expectations of return processing. In those conditions, client demands for higher service quality are the main drivers of effective sustainability operations. This study aims to establish the sustainable reverse logistics service quality (SRLSQ) theoretical framework offered by reverse logistics services providers (RLSPs). The study conducts a systematic methodology protocol by examining reliable academic periodicals using PRISMA guidelines based on the research scope and identified 56 papers from 2011–2022, with the main research focus on SSQ and RLSQ dimensions to develop a research framework. By re-evaluating those factors using the SRLSQ framework and by including sustainability into the service quality approach, this study expanded the practicability of reverse logistic service quality and sustainable service quality. The results point to a knowledge gap when it comes to quantifying the impact of reverse logistics operation process through a triple bottom line approach on customer outcomes, relationship quality (RQ), and mediation of operation risk factor, which could be examined within various contexts in subsequent work.
Keywords: sustainability, reverse logistics, sustainable reverse logistics service quality, customer satisfaction, operational risk

Factors associated with gastrointestinal dysmotility in critically ill patients
Nemanja Petrović, Miodrag Žunić, Ana Pejčić, Miloš Milosavljević, Slobodan Janković, 2023, original scientific article

Abstract: Critical illness may disrupt nutritional, protective, immune, and endocrine functions of the gastrointestinal tract, leading to a state of gastrointestinal dysmotility. We aimed to identify factors associated with the occurrence of gastrointestinal dysmotility in critically ill patients. A cross-sectional retrospective study was conducted, using patient files as a source of data. The study included 185 critically ill patients treated in the intensive care unit of the University Clinical Center, Kragujevac, Serbia, from January 1, 2016, to January 1, 2022. Significant risk factors associated with some form of gastrointestinal dysmotility were acute kidney injury (with paralytic ileus, nausea, vomiting, and constipation), recent abdominal surgery (with ileus, nausea, vomiting, and constipation), mechanical ventilation (with ileus, and nausea), age (with ileus and constipation), and use of certain medication such as opioids (with ileus, gastro-esophageal reflux, nausea, vomiting, and constipation), antidepressants (with ileus, nausea, and vomiting), and antidiabetics (with ileus). On the other hand, Charlson comorbidity index had divergent effects, depending on the form of gastrointestinal dysmotility: it increased the risk of gastro-esophageal reflux but protected against ileus, nausea, and vomiting. In clonclusion, recognition of factors associated with gastrointestinal dysmotility should initiate preventative measures and, thus, accelerate the recovery of critically ill.

Food risk analysis : Towards a better understanding of “hazard” and “risk” in EU food legislation
Ana-Andreea Cioca, Livija Tušar, Tomaž Langerholc, 2023, original scientific article

Abstract: For risk communication, it is important to understand the difference between “hazard” and “risk”. Definitions can be found in Codex Alimentarius and the European Union (EU) General Food Regulation (EC) No. 178/2002. The use of these terms as synonyms or their interchange is a recurrent issue in the area of food safety, despite awareness-raising messages sent by EFSA (European Food Safety Authority) and other interested entities. A quick screening of the EU’s food regulations revealed several inconsistencies. Hence, it was considered necessary to further investigate if regulations could act as a source for this problem. A software tool was developed to support the detection and listing of inconsistent translations of “hazard” and “risk” in certain EU food regulations. Subsequently, native-speaking experts working in food safety from each EU country were asked to provide their individual scientific opinion on the prepared list. All data were statistically analysed after applying numerical scores (1–5) describing different levels of consistency. Results showed that the most common problem was the interchange of “hazard” with “risk” and vice versa. This lack of consistency can create confusion that can further translate into misjudgments at food risk assessment and communication levels.

Visiting nuclear reactors : safety and security aspects
Barbara Pavlakovič Farrell, 2022, original scientific article

Abstract: Visiting nuclear reactors is a niche tourism offer within energy (industrial) tourism, which leads tourists through areas that are not primarily meant for them. Hence, safety and security issues are even more critical in this case. This study aims to highlight different aspects of safety and security issues in nuclear power plant tours and to present measures taken to address these concerns. In addition, we studied the connection between plant visits and the public image of nuclear energy. Information was gathered through participant observation (personal visits of factory tours) and an online survey. There, we identified safety and security nuclear power plant visit protocols and a positive correlation between the visit variable and the two variables of the public image of nuclear energy, which suggests energy (industrial) tourism as a suitable tool to enhance awareness and knowledge about nuclear energy.
Keywords: Nuclear power plants, Energy (industrial) tourism, Safety, Security, Risk, Participant observation

Natural disasters and tourism : Are the risks taken into account?
Aleš Semeja, 2022, independent scientific component part or a chapter in a monograph

Abstract: The tourism sector can be severely affected by unforeseen events, such as natural disasters, which are characterized as events with low probability but high impact. The COVID-19 pandemic came as an unprecedented shock to the tourism sector, with numerous reports appearing in many media outlets showing industry experts and directors calling for outside help to avoid worst-case scenarios for their businesses, even in the early days of the pandemic. We therefore wonder whether the approach of tourism companies to risk was inappropriate. Given the number of natural disasters that have occurred over the past few decades, we cannot argue that there have not been enough warning signs to encourage tourism companies to prepare for unforeseen events. A comprehensive review of natural disasters in recent years can be a valuable tool for tourism companies to assess such risks and develop strategies and action plans to increase resilience and sustainability. The latter should become key components of regular business.

Fuzzy model for estimating the risk of infection by Covid-19
Janez Usenik, 2020, original scientific article

Abstract: The present paper presents a fuzzy model for predicting the risk of a community (country) to being infected by the coronavirus Covid-19. The research is not the medical field, where favourable news about vaccines against this disease is just emerging from the research community. Instead, it presents a relatively simple mathematical model based on the use of fuzzy logic. The model is created as a fuzzy system, in which the basic postulates of fuzzy logic and fuzzy inference are used. The presented model is, of course, only one possibility for describing and predicting the threat to the population due to the Covid-19 disease.
Keywords: Covid-19, fuzzy variable, fuzzy inference, risk of infections

Implementation of food matrix effects into chemical food contaminant risk assessment
Ana-Andreea Cioca, Tomaž Langerholc, Livija Tušar, 2022, original scientific article

Abstract: Food risk assessment plays an important role in protecting public health worldwide. Stakeholders involved in food risk assessment, such as national authorities, agencies, non-governmental organisations (NGOs), industry and consumers, need to properly understand the terminology of food risk assessment effectively. In this respect, the first part of the EU-FORA work programme (WP1) aimed to provide insights into the actual translation of two essential terms used in food risk assessment. ‘Hazard’ and ‘risk’ were first identified and compared between the English version of various food regulations and their equivalents in the national legislation of EU Member States. The comparison and critical evaluation revealed several inconsistencies. These inconsistencies could lead to misinterpretations, followed by errors in conducting risk assessments or communicating risks. We recommend that consistency is restored and maintained so that the message is properly communicated. The second part of the work programme (WP2) was focused on a specific area within chemical risk assessment (CRA). In this context, special attention was given to the impact of the food matrix on the bioaccessibility and bioavailability of heavy metals and metalloids. After collection and careful selection of data from scientific journals, a database with information on the bioaccessibility and bioavailability of cadmium (Cd), lead (Pb), mercury (Hg) and arsenic (As) in different food matrices was created for future statistical analyses related to dietary exposure.
