Purpose – To identify the impact of demographic change factors on the stability of revenue and expenditure of cities with county rights in the Silesian Voivodeship in 2009–2022. Research method – The study was conducted for all 19 cities with county rights in the Silesian Voivodeship. To assess the impact of demographic factors on the stability of total revenue and total expenditure per capita in selected local government units, the multiple regression method and the correlation method were used. Next, to optimally select the explanatory variables for forecasting the amount of revenue and expenditure per capita in selected local government units in 2023, the Hellwig method was used. Results – The results of the conducted research show that the level of the demographic dependency ratio was the factor significantly influencing the amount of total revenue and expenditure per capita in most of the researched local government units in 2009–2022. The presented trend proves that the ongoing demographic processes have an impact on the finances of local government units. In the future, a significant increase in expenditure is expected due to the increasing level of the demographic dependency ratio. Originality / value / implications / recommendations – The research brings added value in terms of testing individual demographic factors that significantly affect the stability of revenue and expenditure of cities with county rights.

Modeling the Non-linear Relationship between the International Prices of Oil and Wheat and the Exchange Rate in Egypt
Authors: Helmy Heba Ezzeldin
Published: January 2025

The Egyptian pound (LE) has experienced multiple devaluations over the last few years. One of the proclaimed causes was the severe rise in the prices of Egypt’s two main imports – wheat and oil – that followed the eruption of the Russian-Ukraine war and inflated Egypt’s import bill, resulting in an increased shortage of the US dollars and creating downward pressures on the LE. Using a nonlinear autoregressive distributed lag (NARDL) method we probe whether an asymmetric relationship exists between Egypt’s exchange rate and each of the international prices of oil and wheat. Short-run asymmetric effects of oil and wheat prices on Egypt’s currency rate were found, as the latter rose in response to upsurges in the oil price and fell in response to downturns in the price of wheat, with no impacts from the opposite changes in the short run. Oil price rises may thus temporarily function as a weak hedge for the LE.

Published: January 2025

The problem of axisymmetric steady magnetic field continuation from flat boundary surface of ferromagnetic is formulated for magnetic flux and scalar potential. Boundary conditions for magnetic flux are not classical because on boundary magnetic flux is unknown and its normal derivative equal zero. The formulation for scalar potential is Cauchy's problem for elliptical partial differential equation. Analytical solutions of the problem are obtained by method of partial solutions, which depend on parameter continuously, and Hankel's integral transformation. It is shown that there are similar properties in problems of axisymmetric fields continuation from flat boundaries of ideal conductor for magnetic field and conductor for steady electric field. It is fixed that field lines, which bound unknown profile, are determined directly by solution of Cauchy's problem for one from two functions. Equipotential lines are calculated to determine of electromagnetic pole profile. References 7, figures 2, table 1.

The torque of a magnetoelectric three-phase torque motor with permanent magnets located on the surface of the internal rotor was studied. The mode of feeding with a sinusoidal current, as well as the mode with injection into the higher har-monic current, are considered. The torque was calculated according to the static model of the magnetic field. It was de-termined that under the conditions of power supply with a sinusoidal current, there is a significant contribution of the sixth harmonic in the pulsations of the torque. The method of suppressing torque pulsations by injecting higher harmonics into the supply current was studied. It is shown that under the conditions of the amplitude of the pulsations of the rotational moment of the sixth harmonic of about 4%, the injection of the fifth harmonic with an amplitude of 2% of the fundamental into the current allows the reduction the pulsations by more than 10 times.

The developed method, which consists in determining the installed power of distributed generation, in particular, a wind power plant, a solar power plant, a standby power plant and the technical parameters of an energy storage system, to ensure the security of the supply of electric energy to local consumers, is given. Achieving a balance between the daily amount of electricity produced by distributed generation and the amount of consumption ensures the determination of excess amounts of electricity, which mainly occur during periods of peak solar radiation and, accordingly, the required capacity of an energy storage system. According to the simulation results, it was determined that with the maximum daily consumption of electricity by local consumers during the year at the level of 96 MWh, the daily balance of electricity is achieved at the installed capacity of the wind power plant at the level of 3.6 MW; solar power plant is 14 MW; standby power plant is 3.7 MW and the nominal power of an four-hour energy storage system is 16 MW.

The modes of reactive power compensation in the power supply system powered by a synchronous generator through a cascade of intermediate transformers have been studied. It is shown that the reactive component of the common complex resistance of the generator and the power transmission path can cause relatively large levels of reactive power in the system. Experiments show that this power remains in the system even after the application of transverse capacitive compensation, which is not able to provide full compensation of reactive power in a power supply system with a cascade of transformers. Under these conditions, the optimal value of the capacitance of the transverse compensation capacitor was found using the search optimization method on the computer model. The results of the study show the possibility of achieving the mode of full compensation of reactive power due to a relatively small increase in the capacity of the compensating capacitor, which provides transverse compensation.

Hermeneuma hieroglyphicorum
Authors: Grimm Alfred
Published: January 2025

The present paper attempts to reveal the sources of a drawing by Giovanni Antonio Dosio (1533–1611) showing an obelisk inscribed with pseudo-hieroglyphs in the context of the classical authorities Diodorus Siculus, Strabo, Tacitus and Pliny the Elder. Dosio's artistic engagement with hieroglyphic studies is a characteristic feature of the humanistic scholarly community of his time. The inscription on the obelisk designed by Dosio proves to be an attempt to formulate the humanae vitae conditio in cryptographic manner by means of pseudo-hieroglyphs, i.e. with symbolic reference to the mysterious wisdom of ancient Egypt.

Authors: Scoglio Arielle A.J. , Chen Yen-Ling , Huang Kuan-Ju , Borgogna Nicholas C. , Potenza Marc N. , Blycker Gretchen R. , Kraus Shane W.
Published: January 2025

Background and aims

Sexual trauma is associated with multiple negative health and social conditions, including compulsive sexual behavior. The present study examined network structures involving sexual trauma history, psychological distress (defined as depression and/or anxiety symptoms), substance use, transactional sex, and compulsive sexual behavior. Prior network analysis work in this area is limited.

Methods

We drew upon two samples of young adults (Sample 1: n = 1,884, 69.3% women; Sample 2: n = 2,337, 69.7% women) recruited from universities in the United States in 2020–2022.

Results

Findings support relationships between sexual trauma and compulsive sexual behavior. Relationships between elements of compulsive sexual behavior, timing of trauma, psychological distress, substance use, engagement in transactional sex, and gender differences were identified. Significant edge strength differences between men and women were observed; distress was a more central node for men, trauma was a more central node for women (Sample 1). When examining elements of CSB, significant gender differences in edge strength were also observed (e.g. connections between dissatisfaction and relapse for men, dissatisfaction and negative consequences for women).

Discussion and conclusions

Specific aspects of CSB closely related to sexual trauma history (e.g., dissatisfaction) and co-occurring psychopathology or clinical concerns (e.g., depression, anxiety, substance use, and engagement in transactional sex) and warrant further attention and study.
From healthy play to gaming disorder: Psychological profiles from emotional regulation and motivational factors
Authors: Castro Cátia Martins , Neto David Dias
Published: January 2025

Background and Aims

The widespread popularity of video games reflects their appeal to meet fundamental needs. This study aims to investigate the psychological factors of gaming use, identifying profiles ranging from healthy to gaming disorder.

Methods

In this cross-sectional study, 5,222 participants were surveyed. This international sample included adolescents and adults (16–69 years, M = 25.6 years, SD = 6.44), 48.66% men (n = 2,541; M = 26.4, SD = 7.03), 42.32% women (n = 2,210; M = 25.1, SD = 5.78), and 9.02% non-binary individuals (n = 471; M = 23.3, SD = 5.23), spanning from casual gamers to esports professional players. Latent Profile Analysis (LPA) was employed to identify distinct psychological profiles. The profile indicators included emotional regulation and motivations for playing video games. The profile correlates analysed included gaming disorder symptoms, time spent gaming and sociodemographics.

Results

The LPA revealed four profiles labelled as avoidant (20.16%), engaged (38.95%), relational (26.01%), and dysregulated (15.78%). Results suggested that the dysregulated profile had the most emotional regulation difficulties, a low level of general motivation, and less interest in recreational gaming, presenting the highest risk for gaming disorder.

Discussion and Conclusions

This study's findings present the first profiles encompassing key detailed psychological factors affecting gamers' behaviour across all game genres, considering three genders. These profiles can aid researchers and clinicians in developing further research on targeted prevention and intervention programs tailored to each profile's characteristics to promote healthy gaming habits and mitigate the risks and harm associated with gaming disorder.

The main method of diagnosing fetal brain anomalies is currently ultrasonography, with magnetic resonance diagnostics being used as an additional tool for verification of identified developmental pathologies. All developmental anomalies are in one way or another associated with a violation of the relationship of brain structures, so the study of the patterns of their intrau-terine development in the norm is an important and nontrivial scientific task, which is of great importance in the clinical practice of perinatal diagnosis. In addition, the boundaries of the norms of geometric characteristics of fetal brain structures are still blurred and require clarification.
In this study, a sample of 105 second and third trimester fetuses without brain pathology was reviewed. The fetal MRI images were analysed to determine the linear dimensions of various brain structures: hemispheres, corpus callosum and cerebellum. To minimise measurement error, data obtained from two radiologists who measured these structures were used. Correlation coefficients were calculated for all pairs of linear measurements. A linear regression method was also applied to assess the relationship between the dimensions of brain structures. Based on the Akaike information criterion, linear and polynomial regression were compared to analyse the statistical models.
It has been shown that the relationship between the increase in individual dimensions: fronto-occipital and biparietal brain diameters, cerebellar corpus callosum length, cerebellar transverse diameter, and worm height, differed according to gestational age. The advantage of a linear model of growth dependence of brain structures for each of the considered dimensions by trimester was proved, compared to stepwise regression. The growth models obtained in the study for linear dimensions and each trimester will allow to determine more accurately whether each particular case of intrauterine brain development corresponds to the norm, using new knowledge about the patterns of relationships of several individual linear dimensions.

Published: January 2025

A methodology for determining maximal anaerobic power and optimal pedaling cadence in sprint cyclists is presented, which is a key factor in track cycling performance. The study examines the impact of pedaling cadence on performance and emphasizes the importance of gear ratio selection for sprints. The research involved 10 professional sprint cyclists aged 15–19 years. Participants performed three maximal sprints with increasing resistance on a cycle ergometer equipped with an electronic braking system and sensors for precise measurement of left and right leg forces and pedaling cadence. This setup enabled the recording of force–cadence and power–cadence relationships. Data analysis was conducted using linear and quadratic regressions. Morphological assessments were conducted, including calculations of fat and muscle mass percentages using anthropometric methods. The study revealed significant interindividual differences in key performance parameters. Maximal power was achieved at an individual-specific optimal cadence, which varied by 20–40 %. The results validate the effec-tiveness of the proposed methodology for tailoring training processes to individual needs. The power–cadence relationship facilitates the determination of the optimal cadence at which max-imal power is attained. The findings underscore that adjusting the gear ratio to achieve the optimal pedaling cadence during sprints enables maximum performance and optimizes effort distribution during critical moments of track competition. The methodology provides tools for analyzing fatigue and other factors affecting performance. It enables precise evaluation of track cyclists' physical capabilities, optimizes training plans, enhances outcomes, and supports personalized tactical strategies, making it valuable for coaches and researchers in biomechanics and sports physiology.
Benchmark Ratio of Insurance Penetration (BRIP) as a New Relative Measure of Insurance Development and Benchmarks in Insurance
Authors: Pobłocka Agnieszka
Published: January 2025

Aim: In various fields of science, certain patterns are used to describe and compare phenomena and reference points (benchmarks), e.g.: reference rates (benchmark rates), reference ratios (benchmark ratio), or comparative analyses (the benchmarking) (EY, 2021). In insurance, premium, density and penetration, among others, are used to describe market development. To compare insurance markets, the average is usually used, e.g. average premium, average density or penetration rate. However, the measures used are limited – premium and density do not take into account economic development – or have been ‘devalued’ (penetration rate is often with different premium and GDP growth rates). In effect, a new, more robust paradigm is being sought, i.e. a new insurance growth pattern. Methodology: This paper analyses and evaluates the benchmark ratio of insurance penetration (BRIP) proposed by (Zheng et al., 2008 and 2009) as a new measure of insurance development and examined its advantages and disadvantages. The arithmetic mean was also analysed as a benchmark for comparing different insurance markets. Findings: The BRIP indicator should be used with caution, as it strongly depends on the benchmark used for comparison. If it is adopted at the level of the arithmetic mean for the whole market, the analysis results may be incorrect when the distribution of the examined phenomenon does not have a central tendency. Implications: The results of the study are a new contribution to the evaluation and application of the BRIP indicator in insurance theory. Originality/value: Zheng et al. (2008, 2009) proposed the BRIP indicator as a new benchmark for the development of insurance markets, without knowing that it cannot always be applied. The author of this study fills this gap and shows when this indicator cannot be applied (DeepL-assisted translation).
Property Supply, Economic Factors and House Prices in Nairobi Kenya

Published: January 2025

Residential real estate is an important asset class for both institutional and individual investors. The housing bubble in the US led to a global financial crisis in 2007 – 2008. As such, understanding the factors that influence property prices is central to the investment process and portfolio management. The objective of the paper was to first construct a Nairobi house price index and then determine the relationship among economic factors, property supply, and house prices. The study period was ten years (2011Q1 to 2020Q4). Autoregressive Distributed Lag (ARDL) model was adopted to estimate long run and short run relationships. The Nairobi real estate price index was developed using hedonic model based on the data collected on actual selling price and characteristics of a sample of houses in Nairobi spanning ten years. The paper finds that GDP and inflation have significant positive long run effect on house prices. Property supply has a significant negative long run effect on real estate prices. However, interest rates do not have significant effect on house prices. In the short run however, GDP had a significant negative effect on prices. The speed of adjustments towards equilibrium relationship was 71.9%. The real estate market seems to be efficient despite its illiquid nature. The paper contributes to knowledge through its construction of house price index in Nairobi. Also, it included property supply a departure from past studies. The findings may have implications for investors, banks, regulators of securities and policy makers. The government of Kenya may be motivated to commission an official house price index.

Descriptions of Mount Tabor in Context of Greek-Latin Relations in the Era of the Crusades
Authors: Pashkov P. A.
Published: January 2025

The article considers a set of problems related to the descriptions of the shrines of Mount Tabor in the era of the Crusades (1096–1291; taking into account the pilgrimage literature preceding this era and descriptions of subsequent centuries). The descriptions created by the Greek and Slavic pilgrims have common features that find no analogues in the texts of the authorship of the Latin pilgrims. The explanation of these contradictions requires the inclusion of medieval itineraries in the general context of Greek-Latin church relations and theological polemics in the Holy Land. A comparative analysis of the descriptions of the holy Mount Tabor showed that in the 12–13th centuries the hidden tension that existed between the “Latins” and the Orthodox manifested itself in a different attitude to the cave church of St. Melchizedek, which, in turn, was closely related to the question of leavened or unleavened liturgical bread, which occupied an important place in theological controversy of the epoch.

Published: January 2025

The article is devoted to the study of the relationship between the Orthodox Church and non-church religious movements in the Balkans in the XX century. The Greek Brotherhood of theologians "Zoi", the Romanian "The Lord’s army" and the Serbian prayer movement arose in similar conditions, but their relations with the clergy and parish clergy developed in different ways. The purpose of the article is to conduct a comparative analysis and identify differences  in  relations with  the official Church and characterize the consequences of the chosen course for Orthodox brotherhoods from a historical perspective. In Russian historiography, this topic has been undeservedly ignored and little studied. The article aims to shed light on the main milestones in the development of the movements under consideration and strategies for building relationships with senior clergy and parish priests.

Availability and quality of infrastructure for physical education and sports as a means of maintaining and strengthening the health of university faculty and staff
Authors: Vorotilkina Irina , Bazhenov Ruslan , Bazhenova Natalia
Published: January 2025

The quality of teaching and maintenance of all university processes depends on the level and state of health of university employees. The health of scientific and pedagogical workers and employees of higher educational institutions is an important component of the active organization of the educational process of the university. In this regard, the creation of a health-saving environment for research and teaching staff and university staff seems to be a fairly urgent task that will preserve and strengthen health, reduce psycho-emotional stress, create a positive attitude to work, develop a desire to create, show a creative approach to work. Positive emotions will create an atmosphere of trust, mutual assistance, and a non-standard approach to solving important and complex tasks. The paper presents an analysis of a study on the problem of accessibility and quality of conditions for active physical education and sports in a university environment. The survey was attended by research and teaching staff and staff of universities in the Far East. The authors note that assessing the accessibility and quality of infrastructure for physical education and sports at universities is an important aspect that affects the health and physical activity of research and teaching staff and employees. The educational environment of the university should create appropriate conditions for the healthy life of both the teacher, employee and student. An integrated approach to assessing the accessibility and quality of infrastructure will help identify both strengths and weaknesses, as well as identify ways to improve conditions for physical education and sports at universities.
Leniência organizacional: examinando as consequências de ignorar problemas de desempenho em organizações públicas
Authors: Tavares Gustavo M. , Wright Bradley E. , Sobral Filipe
Published: January 2025

Resumo A leniência organizacional, definida como a falha sistemática da gestão em lidar com problemas de desempenho (como baixa produtividade, baixa qualidade de trabalho, absenteísmo, etc.), é frequentemente uma realidade em organizações públicas. Propomos que as consequências negativas da leniência organizacional podem ir além da perda de produtividade de alguns funcionários com baixo desempenho. Especificamente, investigamos em que medida a percepção de leniência organizacional pode afetar negativamente o clima organizacional e a satisfação no trabalho dos servidores públicos em geral. Propomos que o efeito negativo da leniência organizacional é mediado tanto pela percepção de reconhecimento recebido quanto pela congruência de valor entre os servidores e a organização, formando um modelo de mediação paralela. Em outras palavras, a percepção de leniência organizacional pode fazer com que os funcionários públicos sintam que seus esforços não são adequadamente reconhecidos e, ao mesmo tempo, diminui a percepção de alinhamento entre seus valores e as práticas da organização. Para testar nossas hipóteses, realizamos uma pesquisa com 256 funcionários do governo de várias organizações públicas no Brasil. Os dados foram analisados utilizando regressão linear múltipla com mínimos quadrados ordinários e testes de mediação. Consistente com nossas previsões, encontramos que a percepção de leniência organizacional está negativamente relacionada à satisfação no trabalho em nossa amostra, e tanto o reconhecimento percebido quanto a congruência de valor mediam esse efeito.
Organizational leniency: examining the consequences of ignoring performance problems in public organizations
Authors: Tavares Gustavo M. , Wright Bradley E. , Sobral Filipe
Published: January 2025

Abstract Organizational leniency, defined as management’s systematic failure to address performance problems (such as low productivity, poor quality of work, absenteeism, etc.), is often a reality in public organizations. We posit that the negative consequences of organizational leniency may extend beyond the lost productivity of a few poor-performing employees. Specifically, we investigate the extent to which perceived organizational leniency may adversely affect the organizational climate and job satisfaction of public employees at large. We propose that the negative effect of organizational leniency is mediated by both perceived recognition received and employee-organization value congruence, forming a parallel mediation model. In other words, perceived organizational leniency may make public employees feel that their efforts are inadequately recognized and also diminishes how much they feel their values align with organizational practices. To test our hypotheses, we surveyed 256 government employees from various public organizations in Brazil. The data were analyzed using multiple linear regression with ordinary least squares and mediation tests. Consistent with our predictions, we found that perceived organizational leniency is negatively related to job satisfaction, with both perceived recognition and value congruence mediating this effect.

Published: January 2025

Resumo Este estudo tem como objetivo analisar as barreiras de gênero para a participação feminina na política brasileira. A coleta se deu por meio de entrevistas semiestruturadas com 22 mulheres do Sudeste e 18 do Nordeste que atuam no ambiente político. Os diálogos foram analisados pelo método de Gioia, e os resultados evidenciam que elas deparam com barreiras psicossociais, culturais e partidárias, reforçando como as políticas de gênero ainda são insuficientes, de modo a dificultar que mulheres se insiram, permaneçam e atraiam outras para a carreira política. Além disso, esta pesquisa apresenta contribuições ao campo teórico e prático sobre a temática das mulheres na política, auxiliando na compreensão sobre os desafios enfrentados no contexto brasileiro e evidenciando como as experiências de violências resultam numa resistência à inserção política e no adoecimento físico e mental.

Published: January 2025

Resumo Este estudo tem como objetivo examinar os efeitos do estabelecimento de metas organizacionais por meio do planejamento estratégico na motivação dos servidores públicos. Fundamentada na teoria das representações sociais, a pesquisa explora os sistemas centrais e periféricos que moldam a representação social desses objetivos. Os dados foram coletados de 324 funcionários públicos por meio de um teste de evocação de palavras, revelando que o estabelecimento de metas organizacionais está positivamente ligado à motivação de alta qualidade e ao ciclo de alto desempenho. O estudo identifica elementos-chave - como metas, eficiência, resultados, planejamento e organização - como centrais para a representação social dos objetivos organizacionais. Estes elementos estão intimamente associados à motivação, sugerindo que objetivos organizacionais claros contribuem para o envolvimento e desempenho dos funcionários. As conclusões também destacam o papel de fatores periféricos, como transparência, alinhamento e bem-estar, que influenciam ainda mais a percepção e implementação do planeamento estratégico. A pesquisa conclui que o planejamento estratégico, seja baseado em abordagens racionais ou emergentes, impacta positivamente a motivação dos funcionários, apoiando assim a execução eficaz das estratégias do sector público.
The how, where, and what of organizational corruption: an integrative literature review
Authors: Coelho Caio , Almeida Sabrina Vieira de
Published: January 2025

Abstract Research on organizational corruption has been approached from different perspectives. However, there is still a lack of a more comprehensive focus on the intersection of public and private management. This article presents a review of 589 academic studies. The predominance of quantitative research suggests the need for a more balanced approach that incorporates qualitative and mixed methods, enabling a deeper investigation of organizational corruption. Furthermore, studies on corruption published in top-ranked English-language journals are mainly concentrated in the northern hemisphere. This methodological dominance shows the need to broaden the scope of the investigations to include the southern hemisphere in these publications. Another aspect observed was the lack of empirical studies and the need to understand corruption as a multidimensional phenomenon. Future research must emphasize primary data analysis to generalize and validate corruption theories.

ABSTRACT BACKGROUND: Preoperative hospitalization with the purpose to obtain more effective weight loss provides intensive care for patients who have a higher body mass index (BMI) and associated diseases that involve a greater risk of peri- and postoperative complications. It is a therapeutic strategy that can make it possible to overcome obstacles related to the difficulty of adhering to obesity treatment. AIMS: To analyze the implementation of a preoperative hospitalization strategy for weight loss in patients eligible for bariatric surgery. METHODS: Retrospective study that included 194 patients with a BMI=50 kg/m2. They were grouped according to preoperative preparation strategies: inpatient (n=32) and outpatient (n=162), who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between 2010 and 2020. The groups were compared regarding preoperative weight loss before and after the strategies and postoperative up to two years after surgery. RESULTS: Most patients were female and there were significant differences in age group (an average of 42.94 years in the preoperative hospitalization strategy group and 37.73 in the outpatient strategy group). The mean BMI in the hospitalized group was 63.01±8.72 kg/m2, and in the outpatient group it was 54.95±4.31 kg/m2. There was a significant difference only between initial and preoperative weight in the hospitalized group. Furthermore, the difference between initial weight and last recorded weight up to two years after surgery was significant in each group. The occurrence of associated diseases was higher in the outpatient group. CONCLUSIONS: Patients following the preoperative hospitalization strategy experienced significant weight loss before surgery.

ABSTRACT BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are uncommon and heterogeneous neoplasms, often exhibiting indolent biological behavior. Their incidence is rising, largely due to the widespread use of high-resolution imaging techniques, particularly influencing the diagnosis of sporadic non-functioning tumors, which account for up to 80% of cases. While surgical resection remains the only curative option, the impact of factors such as tumor grade, size, and type on prognosis and recurrence is still unclear. AIMS: To investigate prognostic risk factors and outcomes in patients with sporadic PNETs treated surgically. METHODS: A retrospective analysis was conducted on patients with sporadic PNETs who underwent pancreatic resection. Data were collected from medical records. RESULTS: A total of 113 patients were included: 32 with non-functioning tumors (NF-PNETs), 70 with insulinomas, and 11 with other functioning tumors (OF-PNETs). Patients with insulinoma were significantly younger, had a higher BMI, lower prevalence of comorbidities and ASA scores, and underwent significantly more pancreatic enucleations compared to patients with OF-PNET and NF-PNET. The insulinoma group had more grade I tumors, smaller tumor diameter, lower TNM staging, and lower disease recurrence rates. In univariate analysis, age, tumor type, tumor size, and TNM staging were identified as potential risk factors for tumor recurrence. In multivariate analysis, only the NF-PNET type was identified as an independent prognostic factor for disease recurrence. CONCLUSIONS: NF-PNETs are an independent prognostic risk factor for disease recurrence. This finding supports the need for closer follow-up of patients with small tumors who are selected for conservative management.

ABSTRACT In patients with synchronic liver colorectal metastasis, resection of the primary tumor and liver metastases is the only potentially curative strategy. In such cases, there is no consensus on whether resection of the primary tumor and metastases should be performed simultaneously or whether a staged approach should be performed (resection of the primary tumor and after, hepatectomy, or hepatectomy first). Patients with no bowel occlusion and with extensive liver disease are advised neoadjuvant oncological therapy. Similarly, various strategies such as portal vein embolization, liver deprivation, two-staged hepatectomy, and associating liver partition and portal vein ligation are available for patients who do not have a sufficient future liver remnant (generally 30-40% of the total). Therefore, a multidisciplinary approach is required for the treatment of these patients.

ABSTRACT The development of surgical techniques, chemotherapy, biological agents, and multidisciplinary approaches have made patients with unresectable colorectal liver metastases eligible for surgery. Many strategies have been developed to allow patients for surgical resection (percutaneous portal vein embolization, liver venous deprivation, parenchyma-sparing liver surgery, reverse strategy, associating liver partition and portal vein ligation for staged hepatectomy, and liver transplantation), the only form of disease control and curative treatment.
THE AMERICAN COLLEGE OF SURGEONS-NATIONAL SURGICAL QUALITY IMPROVEMENT PROGRAM CALCULATOR AND SURGICAL APGAR AS PREDICTORS OF POST-CHOLECYSTECTOMY COMPLICATIONS

ABSTRACT BACKGROUND: Laparoscopic cholecystectomy is considered safe; however, it is not free from complications, such as bile duct injuries, bleeding, and infection of the surgical site. AIMS: The aim of this study was to determine the effectiveness of two prediction tools, the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) calculator and the surgical Apgar, in predicting post-cholecystectomy complications. METHODS: A cross-sectional, analytical, and comparative study was conducted on patients over 18 years old diagnosed with acute cholecystitis who underwent open or laparoscopic cholecystectomy at the Regional Teaching Hospital of Trujillo between 2015 and 2019. A chi-square test was used for bivariate analysis, and the receiver operating characteristic (ROC) curve analysis was employed to determine the discriminative capacity of the ACS-NSQIP and surgical Apgar calculators in predicting severe complications. RESULTS: A total of 227 patients were included in the study. The analysis revealed that the mean age of patients who experienced severe complications was 75.32±4.58 years. Additionally, 52.6% of these patients were male. Regarding the prediction analysis based on the ROC curve, the ACS-NSQIP calculator showed an area under the curve of 0.895 (95%CI 0.819–0.971; p=0.01), whereas the surgical Apgar calculator showed an area under the curve of 0.611 (95%CI 0.488–0.735; p=0.11). CONCLUSIONS: The obtained results indicate that the ACS-NSQIP calculator is effective in predicting severe complications in patients undergoing cholecystectomy due to acute cholecystitis. These findings may have important implications for clinical practice and medical decision-making, focusing on the appropriate use of prediction tools to improve outcomes in this type of surgical procedure.

ABSTRACT BACKGROUND: Hepatocellular carcinoma (HCC) encompasses rare variants like chromophobe hepatocellular carcinoma (CHCC) characterized by distinct histological features and molecular profiles. CASE REPORT: A 56-year-old male with chronic hepatitis C, presenting pain in the right hypochondrium. Imaging revealed a solitary liver lesion, subsequently resected and histologically diagnosed as HCC. Macroscopic examination found a 4×4 cm encapsulated liver nodule with necrotic areas, surrounded by numerous smaller satellite nodules in Segment 6. The liver was in micronodular cirrhosis. Histologically, the tumor had focal trabecular or pseudoglandular patterns within a vascularized stroma. The cells were large, with clear to eosinophilic cytoplasm and hyperchromatic and pleomorphic nuclei with focal anaplastic features. No vascular invasion was noted in adjacent cirrhotic liver tissue. RESULTS: The final diagnosis was CHCC. Due to its rarity and overlapping characteristics with other hepatic tumors, CHCC poses diagnostic challenges. Accurate diagnosis necessitates thorough histopathological assessment and molecular testing. The identification of the alternative lengthening of telomeres phenotype may distinguish CHCC from conventional HCC and hold potential implications for targeted therapeutic approaches. CONCLUSIONS: Recognition of HCC variants is critical for effective management and underscores the need for continued research into its clinical behavior and therapeutic responses.
