Authors: Utami Elika Regni , Hadiprajitno Paulus Theodorus Basuki
Published: February 2025

Bribery is the most serious type of corruption in Indonesia. Business can manage potential bribery practices by implementing Anti-Bribery Management System (ABMS). The ISO 37001 certificate is one part of ABMS and the government requires construction companies to have this certificate. Anti-bribery declaration shows that a company commitment to stakeholders to demonstrate transparency and comply with ethical standards. Implementing this strategy is effective in maximizing stakeholder trust. The objective of this study is to determine the influence of the board of directors on anti-bribery declaration. Characteristics of the board of directors include size, activities, gender diversity and expertise. Directors' activities is shown by how often they have meetings in a year. Gender diversity means having different genders represented, this happens when there are women on the board. Directors' abilities in the field of accounting or finance show their skills. This study was conducted on construction sector companies listed on the Indonesia Stock Exchange in 2020-2023 and obtained data from annual report on the Indonesia Stock Exchange and company website. The sample selection used in this quantitative research was purposive sampling and the results of this selection obtained 17 companies. The analysis techniques used logistic reggression analysis. The results of this study analysis are company’s anti-bribery declaration can be influenced by size, activities, and gender diversity. In contrast, director’s expertise inadequate influence on anti-bribery declaration.

Authors: Sinaga Marissa , Rohman Abdul
Published: February 2025

This study evaluated how pressure, opportunity, rationalization, capability, ego, collusion, and organizational ethical culture influence asset misuse. The research included 294 employees from non-ministerial government agencies in Indonesia, selected using a simple random sampling technique. Data were collected through a questionnaire distributed via Google Forms. To analyze the data, this study used the Structural Equation Modeling Partial Least Square (SEM-PLS) approach. This study found that the variables of capability and ego have no significant influence on asset misappropriation; the variables of pressure, opportunity, rationalization, collusion, on the other hand, have a positive and significant influence on asset misappropriation. Organizational ethical culture can reduce the influence of pressure on asset misappropriation but cannot reduce the influence of opportunity, rationalization, capability, ego, collusion on asset misappropriation. This research helps the government make policies to reduce fraud, especially asset misappropriation. Furthermore, the findings of this study can serve as an evaluation guide to enhance fraud prevention efforts in the workplace, particularly for Indonesian government institutions outside the ministries included in this study
Financial Distress: Studi Intellectual Capital dan Karakteristik Direksi pada Perusahaan Ritel di Indonesia
Authors: Nugroho Wawan Cahyo
Published: February 2025

This research aims to examine the influence of Intellectual Capital and directors' characteristics on financial distress. This research used 90 samples from 15 retail companies listed on the Indonesia Stock Exchange in 2017-2022. Technical data analysts use multiple linear regression. The research results show that intellectual capital has a significant positive effect on financial distress because the value of intellectual capital is a hidden value that gives companies a competitive advantage. This research shows that companies with high intellectual capital values ??will significantly improve their financial conditions and will not experience financial problems. Gender diversity of the board of directors has a significant negative effect on financial distress. This is because in Indonesia, there are still few female board directors and female directors need more time to take policies in predicting company bankruptcy. The age of directors does not have a significant effect on financial distress. This is because young directors, who are considered more open to new things and have a more dynamic way of thinking, will not necessarily benefit the Company if they are not balanced with mature calculations, emotional control and a consistent mindset. Directors' education has a significant positive effect on financial distress, this is because educational background will influence the knowledge possessed by having existing business and economic knowledge so that they have better abilities to manage the business and provide direction in predicting the company's financial distress.

Published: February 2025

The world economy has been in turmoil for the past five years, causing an impact on the company's economy due to the Covid-19 pandemic. where this study is to explore how financial performance mediates the impact of company size, liquidity, and foreign ownership on company value in the consumer goods industry listed on the Indonesia Stock Exchange during 2018 to 2022. Regression analysis, along with the Sobel test, is used to test this relationship. Interestingly, despite the expectation that financial performance can bridge the gap between the independent and dependent variables, the results of the Sobel test show no mediation effect. As a result, the relationship between company size, liquidity, foreign ownership, and company value is direct. For further research, expanding the scope of the study to cover various sectors, extending the time period, and combining various financial ratios can provide a more comprehensive understanding.

Authors: Santana Fabrícia Almeida Fernandes , Marques Lucas Miranda , Almeida Jéssica Bomfim de
Published: February 2025

Este estudo teve como objetivo revisar a literatura sobre a colonização por Mycoplasma e Ureaplasma em gestantes e sua associação com complicações obstétricas e neonatais. A revisão sistemática seguiu as diretrizes PRISMA, incluindo estudos publicados entre 2014 e 2024 nas bases PUBMED/MEDLINE, WPRIM, LILACS e IBECS. Foram selecionadas 60 publicações que investigaram a presença de M. hominis, M. genitalium, U. urealyticum e U. parvum e sua relação com desfechos obstétricos desfavoráveis e complicações neonatais. Os resultados indicaram que a colonização por micoplasmas em gestantes, varia conforme a população estudada, o tipo de amostra coletada e a metodologia diagnóstica. Muitos estudos encontraram associação positiva entre a colonização por Mollicutes e parto prematuro, aborto, ruptura prematura de membranas, corioamnionite e outros desfechos desfavoráveis na gestação. Ureaplasma spp. foi a espécie mais frequentemente detectada, sendo associada a inflamação intrauterina e prematuridade. A presença desses microrganismos no líquido amniótico e placenta foi correlacionada a desfechos neonatais adversos, incluindo síndrome do desconforto respiratório e displasia broncopulmonar. Embora as evidências sugiram um possível papel patogênico dos micoplasmas na gestação, a heterogeneidade dos estudos impede conclusões definitivas sobre sua influência isolada ou combinada com outros microrganismos nos desfechos gestacionais. São necessários estudos prospectivos que analisem a colonização por micoplasmas no contexto do microbioma vaginal gestacional, considerando fatores epidemiológicos e clínicos para uma melhor compreensão de seu impacto na gravidez.

Authors: Irineu Vivian Menezes , Cassemiro Eduarda Ribeiro
Published: February 2025

Objective: To explore and synthesize the existing scientific evidence regarding the key motivators and barriers that impact university students’ decisions to donate blood. Introduction: Although blood donation is essential for public health, donation rates often do not meet the necessary demand. College students are a potential group for donation campaigns because they are young and healthy. Understanding the factors that influence this population to donate blood can contribute to more effective blood collection and retention strategies. Inclusion criteria: The research question that will guide the inclusion of studies was constructed by the PCC strategy, where P- population (students), C-concept (factors that influence blood donation) and C-context (higher education environments): “What are the barriers and motivations for donating blood among students in higher education settings?” Methods: An integrative literature review will be carried out according to the steps described by Souza, 2010. A search will be carried out in a database in the Virtual Health Library (VHL), in the Scientific Electronic Library Online (Scielo) and in PubMed as these are the databases which concentrate a higher degree of indexing of health periodicals. Two independent reviewers will select the studies by title and abstract using the blind on tool in the Rayyan software. The full texts of the included articles will be read and analyzed and data will be extracted using a specific form. Results: Results will be interpreted in light of the literature review and discussed in relation to existing theories on blood donation behavior and health communication.

Published: February 2025

A utilização da cannabis como tratamento medicinal remonta aos primórdios da civilização. Atualmente, a cannabis é utilizada no tratamento de diversas doenças neurodegenerativas e seu uso terapêutico durante o período de fevereiro a abril de 2023. Os resultados revelaram que 58,8% dos participantes eram do sexo masculino e abrangiam várias faixas etárias, com destaque para as idades entre 50 e 85 anos. Entre os participantes, 29,9% eram viúvos e 58% possuíam ensino superior completo. Aproximadamente 58,8% dos participantes utilizavam medicamentos à base de cannabis há menos de um ano, sob prescrição médica e em conjunto com outros medicamentos. Os principais benefícios relatados pelos participantes foram melhorias na memória e no apetite, seguidos pela melhora na concentração e no sono. Esses resultados sugerem um efeito sistêmico dos medicamentos à base de cannabis no organismo, com destaque para melhorias na memória e no apetite. É importante destacar que em 76,5% dos casos, a terapia com cannabis foi realizada em conjunto com tratamentos convencionais. A terapia com cannabis tem se mostrado segura e eficaz, especialmente quando combinada com tratamentos convencionais. Além disso, é importante ressaltar que o uso desses medicamentos idealmente deve ser prescrito por profissionais qualificados, levando em consideração os benefícios e riscos individuais de cada paciente. O uso de canabidiol como terapia complementar mostra-se promissor, mas ainda é necessária mais acessibilidade em relação ao custo dos medicamentos e mais pesquisas para que mais pessoas possam se beneficiar de maneira eficaz desses recursos.
Challenging Perceptions: A Post-Representational Reading of The Fate of Fausto
Authors: Jordan Mairéad
Published: February 2025

As the ‘greening’ of literature for children and young adults continues apace in a time of climate crisis, much research in the field adopts interpretative approaches that analyse representations of nature and the non-human in literature for children and young adults. This article adopts an alternative post -representational approach in its exploration of entanglements of materiality, aesthetics, and paratextuality in The Fate of Fausto by author–illustrator Oliver Jeffers. 1

I argue that The Fate of Fausto presents a performative, material-discursive space, demonstrating intra-actions between creator, process, product, and reader that transcend a limited representational analysis. I propose that this entangled analysis provides deeper insight into the transformative potential of visual literature in reshaping the young reader's perceptions of the world, and also demonstrates the efficacy of a post-representational approach in revealing such potential. The adoption of this approach could yield fruitful results in future ecocritical research on visual narratives for children and young adults.
The Role of Prophylaxis for Preventing Venous Thromboembolism in Major Urological Surgery and Nursing Management
Authors: Kara Senem Güneş
Published: February 2025

Venous thromboembolism (VTE) that includes both pulmonary embolism (PE) and deep vein
thrombosis (DVT), is a common complication in major urological oncology surgery and it is one
of the significant causes of mortality and morbidity. Effective and quality nursing care and practices
at every stage of the perioperative process, from the patient’s initial clinical admission to postdischarge
home care can prevent potential complications. The most effective and the easiest way to
prevent VTE is to perform a proper risk assessment. Nurses providing care to patients undergoing
major urological surgery should conduct a risk assessment through an effective nursing anamnesis
in the preoperative period and take necessary precautions for individuals at risk for VTE. These
precautions should be planned to encompass the intraoperative and postoperative periods as well.
The primary reasons that increase susceptibility to VTE include the pelvic region being the focus
of urological surgeries, the majority of patients being elderly, surgeries typically being performed
in the lithotomy position, and the relatively extended period of postoperative immobilization.
Risk classification, according to national and international guidelines, is categorized as ‘high’ or
‘very high’ risk, with prophylaxis post-discharge considered only for a subset of patients at ‘very
high risk.’ VTE prevention is generally achieved through two main approaches: pharmacological
and non-pharmacological prophylaxis. Pharmacological prophylaxis reduces the likelihood of
VTE, but it is crucial to balance the risk of bleeding with the patient’s experience. Therefore, this
review aims to evaluate the role of prophylaxis and nursing management for preventing VTE in
major urological surgical procedures.
Effect of Stone Density, Skin-Stone Distance and Stone Size on Extracorporeal Shock Wave Lithotripsy Success of Ureter Stones: A Clinical Investigation
Authors: Erdoğan Erhan , Özçelik Fatih , Kahraman Gül , Şimsek Mihriban , Sarıca Kemal
Published: February 2025

Objective: This study aimed to investigate the correlation between demographic characteristics,
stone size, density, and location, skin-to-stone distance (SSD), urinary parameters, and the success
rate of extracorporeal shock wave lithotripsy (ESWL) in patients with ureteral stones.
Material and Methods: A total of 151 patients with ureteral stones were included in this
retrospective study, and ESWL treatment was successful in 116 of them. Stone size, density,
and ureteral location (upper/lower and right/left) were evaluated using non-contrast computed
tomography, and SSD was measured. Demographic characteristics [age, gender, and BMI (Body
Mass Index)] and complete urinalysis parameters (pH, specific gravity, protein, leukocytes,
erythrocytes, casts, and various crystal types) were recorded. The impact of these factors on ESWL
success was statistically analyzed.
Results: A significant negative correlation was found between ESWL success and stone density
[in Hounsfield units (HU)], SSD, and patient age. Treatment success was lower for hard stones
(HU ≥ 1000) compared to soft stones (HU < 1000) (ESWL successful: 28/45 (62%) vs 88/106
(83%), p = 0.006). Similarly, patients with successful ESWL had lower ages and SSD compared to
those with unsuccessful outcomes (41±13 vs 45±9 years and 117±18 vs 125±17 mm, respectively).
Additionally, stones with higher density were found to be larger compared to those with lower
density, with a low-level positive correlation (9.0(4.8-15.0) vs 7.8(4.2-15.0) mm, p=0.0458;
r=0.240, p=0.0029). Binary regression analysis revealed that SSD, stone density (HU), and stone
location significantly influenced ESWL success and could predict outcomes with 78.8% accuracy
(p=0.005, 0.002, and 0.014, respectively).
Conclusion: Increased stone density, longer SSD, and advanced age can decrease the success
of ESWL treatment. This study highlights the importance of considering these variables when
planning ESWL treatment.
International Civil Law Aspects of International Marriage: A Comparative Perspective of Indonesian and Japanese Law
Authors: Sugiastuti Natasya Yunita , Rudyanto Bambang , Dancar Aleksander
Published: February 2025

International marriage is a marriage between two parties with different nationalities. As every country has its own civil law that regulates marriage, international marriage involves aspects of international civil law. This study raises two key issues: first, the determination of applicable laws related the material and formal conditions of marriage; and second, the citizenship of spouses as well as children in an international marriage. The discussionadopts a comparative perspective, focusing on Indonesian and Japanese legal systems. Â Â This study employs normative legal research, utilizing a statutory and comparative approach, analyzing primary, secondary, and tertiary legal materials through qualitative methods and inductive conclusions. Results of the study indicate conceptual similarities between Indonesian and Japanese law in the area under study. First, material conditions of international/mixed marriage are determined based on the principle of lex patriae, while formal conditions are based on the lex loci celebration. principle Second, international marriage does not cause the spouses to automatically lose their own or obtain the citizenship of their spouse but can only obtain the citizenship of their spouse through a naturalization application. Children born in international marriages obtain citizenship based on the principle of ius sanguinis, and if this leads to dual citizenship, within a certain period of time the child must choose one of the nationalities. The existing literature concerning international marriage indicates that there is a gap of research with comparative approach between Indonesian and Japanese law. Thus, in addition to enriching the study of law related to international marriage, the results of this study can be used as educational materials for the Indonesian diaspora in Japan and vice versa.

Published: February 2025

As a previous result, it has shown that every sphere-link consisting of trivial components is a ribbon sphere-link. In this note, it is shown that for every closed oriented disconnected surface F with just one non-sphere component, every F-link consisting of trivial components is a ribbon surface-link. Further, it is shown that for every closed oriented disconnected surface F containing at least two non-sphere components, there exist a pair of a ribbon F-link and a non-ribbon F-link that consist of trivial components and have meridian-preservingly isomorphic fundamental groups.
Stochastic Control in Determining a Soccer Player's Performance
Authors: Pramanik Paramahansa
Published: February 2025

This paper explores recent advancements in utilizing the dynamic programming approach to determine optimal stubbornness in professional soccer matches. Traditional discrete methods often become challenging due to the curse of dimensionality. To address this, we employ a stochastic control framework to maximize a soccer player's objective function, with goal dynamics expressed by a stochastic dierential equation. Solving a high-dimensional Hamilton- Jacobi-Bellman (HJB) equation numerically is very complicated. As a solution, a Feynman-type path integral method is proposed as a more ecient alternative.

Published: February 2025

Advanced silicate nano-sheets as exfoliated and separated layers were developed from natural glauconite and hybridized with methanol, producing a methoxy exfoliated structure (Mth/EXGL). The structure was assessed as an enhanced carrier of the cisplatin drug (CSPN) with significant loading, release, and cytotoxicity properties. The methoxy form of exfoliated glauconite showed better loading properties (327.7 mg/g) than the exfoliated sample (202.4 mg/g) as well as the raw sample (119.3 mg/g). This enhancement was assigned to the incorporated active loading centers after the methanol hybridization step, which is in agreement with the steric studies and determined active site density (Nm = 45.5 mg/g (Mth/EXGL), 38.4 mg/g (EXGL), and 26.3 mg/g (glauconite). Moreover, each site across the interface of Mth/EXGL has the capacity to be loaded with 8 CSPN molecules, donating multi-molecular mechanisms and their loading in vertical orientation. The CSPN loading energy value (<8 kJ/mol) into Mth/EXGL reflected the dominant impact of the physical mechanisms, including electrostatic attractions and hydrogen bonding. The recognized release profile demonstrates continuous and controlled behavior that can extend up to 110 h at pH 7.4 and 170 h at pH 5.5. This releasing behavior is regulated by two main processes (diffusion and erosion) based on the release kinetic findings. Also, Mth/EXGL as a carrier of CSPN induces its cytotoxic effect on human cervical epithelial tumors (HeLa) (0.65% cell viability) as compared to the free form of CSPN (6.6% cell viability). The Mth/EXGL is recommended as a delivery system for CSPN considering its determined loading, release, and cytotoxicity properties.
Spin polarized nodal loop state at Fermi level in the monolayer PrClS
Authors: Zhao Yilin , Zhang Li , Gao Yufeng
Published: February 2025

The investigation of two-dimensional materials exhibiting half-metallicity and topological features has become a rapidly growing area of interest, driven by their immense potential in nanoscale spintronics and quantum electronics. In this work, we present a comprehensive study of a two-dimensional PrClS monolayer, revealing its remarkable electronic and mechanical properties. Under its ferromagnetic ground state, the PrClS monolayer is shown to exhibit half-metallic behavior with 100% spin polarization originating from the spin-up channel. Of particular significance is the discovery of a spin-polarized nodal loop state within the spin-up channel. This intriguing state, characterized by a critical dispersion type and its precise alignment with the Fermi energy level, represents a feature of great interest for practical spintronic and quantum applications. Further analysis of the nodal loop topology using a maximally localized Wannier tight-binding Hamiltonian unveils distinct topological edge states. These edge states emerge clearly from the nodal loop crossings and are entirely separated from the bulk band projection, ensuring enhanced experimental detectability. The robustness of this nodal loop state is also explored under the influence of spin-orbit coupling, where it transforms into a unique hourglass-shaped dispersion while maintaining its fundamental characteristics, further solidifying its potential for experimental validation and deployment in advanced technologies. To assess the applicability of the PrClS monolayer in practical settings, its mechanical properties were thoroughly evaluated and several key parameters were analyzed, revealing significant mechanical anisotropy. This anisotropy underscores the importance of directional dependence in structural engineering and highlights the material’s versatility for applications requiring tailored mechanical responses. Overall, the PrClS monolayer represents an exceptional platform for investigating spin-polarized topological phenomena and demonstrates strong potential as an exciting material for both fundamental research and technological innovation.

Purpose

To evaluate the prognostic value of Low-density lipoprotein receptor-related protein 1 (LRP1) in patients with acute ST-segment elevation myocardial infarction (STEMI) following percutaneous coronary intervention (PCI).

Method

This prospective study included 96 STEMI patients who underwent PCI and 19 control subjects with normal coronary arteries. Coronary blood was taken from both groups, and LRP1 expression levels were quantified using real-time quantitative PCR (qPCR). The STEMI patients were stratified into low, middle, and high LRP1 groups based on tertiles of LRP1 expression. The primary endpoint was the occurrence of major adverse cardiovascular events (MACE) during a six-month follow-up period post-PCI.

Results

LRP1 expression in arterial blood was significantly lower in the STEMI group [0.63(0.23,1.1)] compared to the control group [1.5(0.84,1.85)] (P < 0.05). The incidence of MACE showed an increasing trend across the LRP1 tertiles: 6.7% (95% CI: 1.9–21.3%) in the low LRP1 group, 22.6% (95% CI: 11.4–39.8%) in the middle LRP1 group, and 41.9% (95% CI: 26.4–59.2%) in the high LRP1 group. The high LRP1 group exhibited a significantly higher MACE rate compared to the low LRP1 group (P < 0.05). Spearman's rank correlation analysis revealed positive correlations between LRP1 and both NT-proBNP and cTnT (r = 0.349, 95% CI: 0.156–0.515, P < 0.001; r = 0.328, 95% CI: 0.133–0.497, P = 0.001, respectively), and a negative correlation with LVEF values (r = −0.285, 95% CI: −0.460 to −0.087, P = 0.006). Receiver operating characteristic (ROC) analysis identified an LRP1 expression threshold of 0.79 for predicting MACE within six months post-PCI, with a sensitivity of 81.8% (95% CI: 61.5–92.7%), a specificity of 70% (95% CI: 58.5–79.5%), and an area under the curve (AUC) of 0.789 (95% CI: 0.688–0.890, P < 0.001).

Conclusion

LRP1 expression appears to be an independent predictor of MACE in STEMI patients and may have prognostic value for short-term outcomes following PCI.
Flexible control switching method for converter station in LCC-HVDC transmission system
Authors: Peng Maolan , He Xiaopeng , Xiao Ran , Feng Lei , Liao Fangqun , Jiang Wen
Published: February 2025

Line Commutated Converter based High Voltage Direct Current (LCC-HVDC) transmission technology has the advantages of high withstand voltage and large current capability and has been widely used in renewable energy transmission. However, the power intermittency and fluctuation of renewable energy sources (RESs) such as wind and solar power will result in complex and variable operating conditions of the AC power grid. A single converter control strategy is difficult to adapt to all operating conditions, affecting the safety and stability of the system. Therefore, this paper first establishes the state-space model of the LCC-HVDC system with renewable energy at the sending-end and analyzes the small-signal stability and stable operating range of the system under different control strategies. Then, based on the designed control switching principles, a flexible control switching method applicable to the LCC-HVDC system is proposed. This method can not only enhance the stability of the system, but also ensure a smooth switching between different control strategies with minimal disturbance to the system. Finally, a simulation model is built on the PSCAD/EMTDC platform to verify the feasibility of this flexible control switching method. The simulation results show that the disturbance during the control switching is relatively small, and the flexible control switching method can effectively ensure the stable operation of the LCC-HVDC system under different operating conditions.

Introduction

The systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI) have recently been reported as novel inflammatory markers of diabetes. However, the associations of SII and SIRI with the risk of gestational diabetes mellitus (GDM) are unclear. In our study, we explored the association between the SII and SIRI in early pregnancy and the risk of GDM in pregnant women.

Methods

A prospective cohort of 1,505 pregnant women were recruited at 6–13 weeks of gestation in 2019 and 2020 in Shenzhen, China. SII and SIRI were determined by calculating the composite inflammation indicators from routine blood test results at 6–13 weeks of gestation, and an oral glucose tolerance test was conducted at 24–28 weeks of gestation to diagnose GDM. Logistic regression was used to analyse the correlations between the incidence of GDM and SII and SIRI. Using a restriction cubic spline with baseline SII and SIRI as continuous variables, the dose–response associations between the incidence of GDM and SII and SIRI were explored.

Results

Following Ln-transformation of the SII and SIRI, multivariate models showed that Ln (SII) (odds ratio [OR] = 1.759; 95% confidence interval [CI]: 1.272–2.432) and Ln (SIRI) (OR = 1.556; 95% CI: 1.187–2.042) were positively associated with the risk of GDM in a dose-dependent manner. The OR for the highest quartile of SII compared with the lowest quartile for the risk of GDM was 2.080 (95% CI: 1.447–2.990), and the OR for the highest quartile of SIRI compared with the lowest quartile was 1.694 (95% CI: 1.170–2.452). The restricted cubic spline model confirmed a linear association between Ln (SII) and Ln (SIRI) with the risk of GDM (p-nonlinear > 0.05).

Discussion

Higher SII and SIRI in early pregnancy are associated with an increased risk of GDM. As novel, valuable, and convenient indicators of inflammation, SII and SIRI could be used to a potential predictor for GDM in early pregnancy.
Efficacy and safety of parathyroid perfusion assessment by fine-needle prick during thyroid surgery: a prospective study
Authors: Wang Peisong , Xue Haowen , Wang Xin , Xue Shuai
Published: February 2025

Objective

This prospective study aimed to analyze the efficacy and safety of fine-needle prick (FNP) in the assessment of parathyroid gland (PG) perfusion during thyroid surgery.

Methods

A total of 147 patients with papillary thyroid carcinoma (PTC) who underwent lobectomy with therapeutic unilateral central lymph node dissection (CLND) performed by the same surgeon at the First Hospital of Jilin University between June and September 2024 were included in this prospective study. Following removal of the thyroid and unilateral central lymph nodes, indocyanine green (ICG) was prepared and administered intravenously. Fluorescence signals and images were captured using a near-infrared system to obtain the ICG1 score. Approximately 5–10 min thereafter, the fluorescent signal dissipated, after which the preserved PG was evaluated using FNP. An FNP score was established based on oozing blood from the parathyroid. After hemostasis was achieved by compression with gauze, ICG was reinjected to reassess PG perfusion, which yields the ICG2 score.

Results

In 13 patients, only one parathyroid was identified, while the other was inadvertently excised during surgery. A total of 269 (95.73%) parathyroids were evaluated, with consistent scores observed between the use of the ICG1 and FNP methods. However, in six congested PGs with a darkened appearance, the FNP method could not accurately assess blood supply due to the slow oozing of accumulated blood following the procedure. The Spearman’s correlation coefficient between the ICG1 and FNP methods was 0.973 (p < 0.001), demonstrating strong concordance in determining PG blood supply. Furthermore, the identical ICG1 and ICG2 scores indicated that FNP did not adversely affect PG perfusion.

Conclusion

The FNP test could represent a safer, simpler, and more reliable alternative to ICG for the assessment of PG perfusion. However, further validation in patients undergoing total thyroidectomy and bilateral CLND is warranted.

Published: February 2025

Objective

The study aimed to investigate the diagnostic value of 18F-AlF-NOTA-Pentixafor PET/CT in subtyping primary aldosteronism (PA).

Methods

This study enrolled 88 patients with PA or nonfunctional adenoma (NFA) for 18F-Pentixafor PET/CT scan. Of these, 20 patients underwent adrenal venous sampling (AVS), and 65 underwent adrenalectomy and postoperative follow-up.

Results

In 88 patients, 76 were diagnosed with unilateral PA (UPA), 4 were diagnosed with bilateral PA (BPA), and 8 were diagnosed with NFA, resulting in a total of 95 lesions. To identify UPA, visual analysis received a specificity of 94.12% and a sensitivity of 89.74%. The optimal cutoff values for SUVmax at 5.45, the lesion-to-normal adrenal ratio (LAR) at 1.43, and lesion-to-liver ratio (LLR) all yielded a specificity of 100% and a sensitivity of 79.49%, 83.33%, and 80.77%, respectively. In 15 adrenal lesions with similar uptake to contralateral and adjacent normal adrenal tissue (defined as warm lesions), 7 were confirmed as UPA, 4 were confirmed as BPA, and 4 were confirmed as NFA. Furthermore, among the 20 patients who underwent AVS, the concordance rate of AVS and PET/CT visual analysis for PA subtyping was 65.00%.

Conclusions

The CXCR4-targeted 18F-AlF-NOTA-pentixafor PET/CT is a valuable noninvasive tool for diagnosing UPA, demonstrating high sensitivity and specificity. More attention should be paid to warm adrenal lesions for their high diagnostic ambiguity probability.
