Published: February 2025

This paper analyses the influence of macro-environment on the efficiency of small and medium-sized enterprises (SMEs) in the Republic of Serbia (RS) in period from 2004 to 2021. The aim of the paper is to identify the factors that have a positive impact on the SMEs’ business i.e. encourage their development, as well as factors with negative impact which limit their further growth. Our starting assumption is that the macro-environment has a positive impact on the development of SMEs due to the fact that number of SMEs and number of their employees and their business performances has been constantly increasing throughout the observed period. By applying regression method, on the sample of 75,000 SMEs (in 2004) to a sample of 109,000 SMEs (in 2021), impact of legal-political, economic, social, technology-related factors on ROA of SMEs in RS is examined. The results show that political instability and inefficiency in relation to the law application are a great hindrance in the development of SMEs in the Republic of Serbia, while the continuous growth of the economic activity (accompanied by an increase in the standard of living), social change (accompanied by collective welfare) and technological improvement have positive effect on the efficiency of SMEs in RS.
How the big five psychological factors affect phishing: A literature review
Authors: Gordon Alex , Russ-Eft Darlene 
Published: February 2025

Abstract
Phishing is a social engineering attack which intends to steal information from an intended victim by masquerading as a reputable source. It is a ubiquitous problem in modern day society and organizations, which is not likely to slow down.
The Big Five psychological factors model is one which is widely used and has been shown to largely explain how someone behaves.
Yet the results of the Big Five factors’ interface with phishing response is not clear as of yet. The purpose of this study was to elucidate the interactions between phishing and the Big Five factors.
This study used an integrative literature review method to examine the relationship between the Big Five psychological factors and the phishing response. This theoretical model developed from the research can then be used to suggest human resource development (HRD) interventions within organizations. Such interventions can aid both the organizations and their employees to avoid the negative outcomes from phishing.
To design and implement the QoS -Aware Energy Efficient Routing Mechanism for the BAN-IoT networks in Smart Health care Applications.

Published: February 2025

Abstract
The integration of Internet of Things (IoT) and miniature implantable sensors has significantly advanced Body Area Networks (BAN) for real-time monitoring of patients' physiological vital signs, including Electrocardiogram (ECG), Electromyogram (EMG), and Electroencephalogram (EEG). However, the limited bandwidth of wearable nodes and frequent body movements result in recurrent topological changes, causing unreliable and delayed transmissions. To address these challenges, a reliable and low-latency routing mechanism is required to ensure lossless data transfer and support timely clinical treatments. This paper proposes a QoS-aware routing protocol that dynamically calculates optimal routing paths by integrating Chaotic Theory with the Honey Badger Optimization (HBO) algorithm. The proposed protocol selects latency-aware, energy-efficient paths using key metrics such as Link Quality Factor (LQF), Distance (D), Received Signal Strength Indicator (RSSI), and Number of Hops (NoH) to achieve reliable and efficient data transmission. Comprehensive experiments are conducted in the Python 3.9 environment, and performance metrics including Packet Delivery Ratio (PDR), End-to-End Delay, Throughput, Routing Load, and Control Packet Overhead are calculated and compared with other existing optimization models. The proposed model is also statistically validated against state-of-the-art protocols. Results demonstrate superior performance and stability, effectively overcoming existing bottlenecks and providing improved QoS for IoT-enabled BAN systems in smart healthcare applications.

Abstract
A 56-year-old woman, known in her past medical history with uncorrected atrioventricular septal defect, secondary pulmonary hypertension, and permanent atrial fibrillation, with repeated hospitalizations for congestive heart failure over the years, presented to the Emergency Department for repeated syncopal episodes. Holter monitoring detected atrial fibrillation with periods of asystole. While most cases in the literature mainly focus on patients with isolated atrial septal defects (ASD)(1), we present a case of a challenging pacemaker implant in a patient with transitional atrioventricular septal defect (AVSD). The case illustrates the challenges of differential diagnosis of syncope and of implanting a pacemaker in adults with congenital heart disease, underscoring the importance of an excellent understanding of electrophysiology, defect anatomy, and postoperative alterations. In addition, this case emphasizes that structural heart disease can be a potential cause when assessing recurrent syncope. When selecting the implantation and pacing modes, operators must consider the possibility of multiple reimplantation throughout the patient’s lifespan.

Introduction. Surgical treatment of patients with urgent abdominal surgical pathology is associated with a high risk of developing various somatic complications. The most common of them is acute kidney injury (AKI), which is an independent factor in increasing the duration of hospitalization and mortality.The objective was to develop a prognostic model of individual risk of AKI after surgical treatment of patients with urgent abdominal surgical pathology.Materials and methods. A cohort comparative study of the treatment outcomes of 271 patients with urgent abdominal surgical pathology was conducted. The primary endpoint was the development of AKI. The main group included patients (N = 134) whose early postoperative period was complicated by AKI, and the control group (N = 137) included patients without this complication. Binary logistic regression analysis was used to build a model for predicting the probability of AKI development, which included statistically significant predictors. ROC analysis was performed to determine the sensitivity and specificity of the resulting individual risk model for AKI.Results. It was proven that type 2 diabetes mellitus (p = 0.003), early stages of chronic kidney disease (p = 0.026), and mechanical jaundice (p < 0.001) were significantly more often verified in patients of the main group. In the AKI group, the levels of creatinine (p < 0.001), urea (p < 0.001) and proinflammatory cytokines – tumor necrosis factor alpha (p < 0.001) and C-reactive protein (p < 0.001) were significantly higher. Based on the obtained results, a model for predicting the individual risk of AKI was developed using binary logistic regression analysis, the sensitivity and specificity of which were 82.8% and 88.3%, respectively. High validity of the proposed model was proven.Conclusion. The proposed model allows predicting a reliable individual risk of acute kidney injury after surgical treatment of patients with urgent abdominal surgical pathology.

Introduction. The increasing prevalence of healthcare-associated infections (HAIs) caused by critical, high and medium priority pathogens among patients with severe community-acquired pneumonia (SCAP) and the high mortality rate necessitate monitoring of pathogens and consideration of predictors.The objective was to identify predictors, determine the etiology and evaluate the dynamics of pathogens of HAIs over a 10-year period in patients with SCAP.Materials and methods. An analysis of medical records of 756 patients treated in the intensive care unit was of the I.I. Mechnikov NWSMU was conducted in the period from 2013 to 2023. Incidents of HAIs (catheter-associated urinary tract infection – CAUTI, catheter-associated bloodstream infection – CLABSI) and ventilator-associated pneumonia – VAP) were determined in accordance with the NASCI criteria from 2023.Results. The study included 663 patients with SCAP. The density of HAIs in patients with SCAP was 6.2/1000 days of device use (DDU) and shows an increase in the period 2021–2023. The frequency of CLABSI caused by multiple drug resistance (MDR) pathogens was 69.2%, CAUTI 24.4%, VAP 42.9%. 72 cases of HAI were registered in 67 patients, of which 24 (35,8%) patients with SCAP had 50 critical and high priority pathogens, of which 16 (23.8%) had bacterial-fungal associations. The priority pathogens in the registration of DAIs for the entire analyzed period were carbapenem-resistant strains of A. baumannii and K. pneumoniae as well as K. pneumoniae isolates resistant to third-generation cephalosporins. A trend towards expanding the spectrum of pathogens and increasing the proportion of Candida non-albicans in the etiological structure of fungal HAIs was identified in the period 2021–2023. Independent predictors of DAIs were identified in patients with SCAP, which were > 7 DDU for CLABSI, and > 72 hours of mechanical ventilation for VAP, and an increase in procalcitonin > 0.5 ng/ml for VAP and CAUTI. When registering CAUTI, the severity of comorbidities (CCI score ≥ 5: 3.829; 1.867–7.852, p < 0.001) in patients with SCAP and the severity of organ dysfunction (SOFA score > 4.0 (9.976; 1.277–77.958, p = 0.028) in patients with SCAP COVID-19 were independent predictors of HAIs.Conclusion. In the period 2021–2023, an increase in HAIs was observed in the group of patients with SCAP. The main pathogens of which were critical, high and medium priority pathogens K. pneumoniae, A. baumannii, as well as Candida spp. (C. tropicalis, С. parapsilosis, P. kudriavzevii). Independent predictors of HAIs in patients with SCAP were identified, which were the duration of use of devices and the increase in the level of procalcitonin above 0.5 ng/ml. When registering CAUTI, risk factors such as the severity of comorbidities for patients with SCAP and the severity of organ dysfunction in patients with SCAP COVID-19 were identified.

Introduction. The knowledge and experience of anesthesiologists about predictors of unplanned ICU (intensive care unit) readmission are implemented into practical models for their prevention. However, differences in the time before patient’s ICU readmission make significant adjustments to the possibility of their implementation.The objective was to analyze intensivist opinions about predictors of early and late unplanned ICU readmissions. Materials and methods. The survey of intensivists was conducted in 9 hospitals in Saint Petersburg and the Leningrad Region from July 2023 to July 2024. Statistical information processing was carried out using the Jamovi software package.Results. The study included 381 questionnaires. Long ICU stay ( > 14 days) (AOR: 0.373; 95% CI: 0.183–0.758, p = 0.006; 0.492; 0.246–0.985, p = 0.045), emergency surgeries and procedural complications (1.283; 1.071–1.537, p = 0.007; 1.387; 1.136–1.694, p = 0.001), as well as lack of data on oxygen therapy and respiratory support in the transfer epicrisis (0.315; 0.172–0.576, p < 0.001; 0.505; 0.278–0.919, p = 0.025) increase the chances of 24- and 48-hour unplanned ICU readmission. Transfer of patients from the ICU to «off-hours» (1.244; 1.020–1.517, p = 0.031; 1.518; 1.243–1.853, p < 0.001) was a risk factor for the 48- and 72-hour periods. Registration of adverse acute cardiovascular events (2.876; 1.368–6.047, p = 0.005; 2.578; 1.390–4.780, p = 0.003) increased unplanned ICU readmission in the 48-hour and 7-day periods. Sepsis in a patient in the ICU was considered by respondents to be an independent predictor of ICU readmissions for all periods except the 24-hour period. Characteristic predictors of unplanned ICU readmissions also were: for 24-hour – the impossibility of conducting «round-the-clock» laboratory and instrumental diagnostics (0.764; 0.639–0.914, p = 0.003), patient readmission due to the need to free up a ICU bed (1.345; 1.138–1.589, p = 0.001), failure to hold council (0.507; 0.270–0.954, p = 0.035); for 72-hour – physician experience (0.968; 0.939–0.997, p = 0.033); for 14 days – Mechanical Ventilation > 7 days (1.674; 1.025–2.734, p = 0.040).Conclusion. The analysis of the opinions of intensivists made it possible to identify independent and determine modifiable predictors of early and late unplanned readmission of the patient to the ICU.

Background
IgA nephropathy (IgAN) is the most common form of glomerulonephritis globally, and a leading cause of end-stage kidney disease (ESKD). In India, IgAN accounts for 10-15% of kidney biopsies, often with nephrotic syndrome and renal impairment. Steroids are the mainstay of treatment, though the role of mycophenolate (MPA) is less explored. This study investigated the outcomes of MPA in IgAN.

Materials and Methods
This retrospective study included patients ≥18 years old with biopsy-proven IgAN from January 1, 2010, to December 31, 2017, and eGFR >15 mL/min/1.73m2. Patients were treated with angiotensin receptor blockers (ARBs), steroids, and MPA based on disease activity. The cohort was divided into three groups: ARB, ARB+prednisolone, and ARB+prednisolone+MPA. eGFR and proteinuria data were collected at baseline, 12, 36, and 60 months and compared between groups.

Results
IgAN comprised 16.7% of kidney biopsies. The mean age of patients was 36.6±10.1 years, with 88.9% having hypertension. Over 60 months, eGFR decreased by 2 mL/min/1.73m2 in both groups, with 16.4% of patients in the MPA group progressing to ESKD, compared to 18.4% in the steroid group (p=0.42).

Conclusion
MPA, in addition to steroids and ARBs, may help mitigate IgAN progression, though there were no differences in ESKD progression. Further randomized controlled trials are needed to validate the role of MPA in IgAN treatment.

Published: February 2025

В статье рассматриваются принципы работы Л. Берио со словом в электроакустической композиции «Тема. Приношение Джойсу» («Thema. Omaggio a Joyce»). Предметом исследования является понятие вербальной «темы» и принципов работы с ней по аналогии с принципами полифонической разработки музыкальной темы. Сочетание нескольких подходов лежит в основе анализа пьесы. Произведение рассматривается 1) с точки зрения Klangfarbenmelodie, основанной на сопоставлении звуковых пластов или характерных сочетаний звуков; 2) с точки зрения архитектоники формы, основанной на сопоставлении тематических элементов (слов и последовательностей слов); 3) в качестве вторичного фактора отмечен интонационный фактор, в частности, рассматриваются предпосылки формирования музыкально интонируемого звука из чисто речевых элементов композиции. Проведенный анализ показал, что вербальная тема в «Omaggio a Joyce» раскрывает не только ярко выраженную фоническую функцию в подобии Klangfarbenmelodie, но и конструктивную архитектоническую роль. Тематические элементы в «Omaggio a Joyce» несут и определенную смысловую нагрузку, связанную с их использованием в тексте литературного первоисточника.
The article is devoted to analysis of the principles of elaboration of word in the electro-acoustic composition «Thema. Omaggio a Joyce». The subject of research is the concept of a verbal «theme» and principles of working with it, by analogy with the principles of polyphonic development of a musical theme. A combination of several approaches underlies the analysis of the work. The work is considered 1) from the point of view of Klangfarbenmelodie, based on a comparison of sound layers or characteristic combinations of sounds; 2) from the point of view of the architectonics of the form, based on a comparison of thematic elements (words and sequences of words); 3) the factor of musical intonation is noted as a secondary factor. In particular, the article discusses the prerequisites for the formation of a musically intonated sound from purely speech elements of the composition It is concluded that the verbal theme in «Omaggio a Joyce» reveals not only a pronounced phonic function in the likeness of Klangfarbenmelodie, but also a constructive architectonic role. The thematic elements in «Omaggio a Joyce» also bear a certain semantic load, connected with their use in the text of the literary source.
