Published: February 2024

Residual sugars (RS) in wine are the sugars that remain in a wine after fermentation is complete. In some wine styles, such as semi-dry wines, the accurate measurement of the RS concentration is critical for both qualitative and legislative reasons. Brix, measured by a simple refractometer, can give a good estimation of the RS concentration in the must, but during fermentation, the presence of alcohol leads to inaccurate sugar measurements. In order to measure the RS accurately, other more precise techniques are used, most of which are expensive or require professional skills. Therefore, novel approaches for rapid, easy, and practical measurements for estimating the sugar content were suggested over the years. However, most of these methods do not supply an actual measurement of RS but rather give brix values, and those that measure RS involve special equipment, which is less relevant for small wineries. This study suggests a novel model for predicting and controlling the wine's residual sugar. The data the model uses is the initial brix of the must before fermentation and its density during fermentation. The model was created by measuring actual residual sugars during the fermentation of natural and synthetic musts, with various degrees of initial brix levels, while simultaneously measuring their densities and correlating the two measurements. Linear regression between the residual sugar of the wine and its density was obtained for all treatments and repetitions (i.e., different values of must initial brix) with R2 values above 0.97. Using the model, one can calculate (before commencing the fermentation) the density values at which the fermentation will reach a particular desired residual sugar value for a specific initial brix level; the model is applicable for the fermentation conditions used in this work, i.e., brix levels of 18-27˚Bx, Saccharomyces cerevisiae strains (fx-33 and fx-10) in common conditions of fermentation regarding temperature and aeration.

Published: February 2024

Soil moisture can be an important indicator of climate change in humid and semi-arid areas. This indicator can more efficiently propose different public policies related to climate change than just using precipitation and temperature data. Given the above, the objective of this study is to evaluate changes in soil moisture in the state of Pernambuco during the period 1961-2021, using the System of Hydrological Response Units for Pernambuco. In this study, five river basins in the state of Pernambuco that represent the different climatic conditions of the state will be chosen. The results show that in the coastal region, there is a tendency towards more saturated soils, and in the semi-arid region, there is a tendency towards drier soils. With these results, it is possible to conclude that public policy decisions for the economy, environment, and society must consider this vital water balance variable.

Authors: Ismail Andy , Dora Yenny Maya , Hidajat Taofik
Published: February 2024

This research challenges the traditional perspective on consumer behavior, which focuses on external factors shaping the sequential stages of decision-making. Instead, it proposes a paradigm shift by treating the decision-making process itself as an independent variable, exploring its impact on various outcomes like purchasing behavior, brand loyalty, and post-purchase satisfaction. This novel approach offers deeper insights into the intricacies of consumer behavior, particularly in the digital age. By uncovering the reciprocal relationships between the decision-making process and other variables, the research provides a more nuanced understanding of how consumers navigate today's complex landscape. It further delves into how variations in the decision-making process across diverse consumer groups influence various outcomes, recognizing the unique characteristics and needs of different demographics. The research also acknowledges the interplay of psychological, social, and contextual factors that shape both the decision-making process and its downstream effects, offering a comprehensive understanding of the multifaceted influences on consumer behavior. Ultimately, by studying the decision-making process as an independent variable, this research aims to equip businesses and researchers with valuable insights, enabling them to better navigate the ever-evolving world of consumer behavior.

Published: February 2024

In recent years, the manufacturing sector has benefited from a variety of technological innovations regarding automation and utilization of artificial intelligence on the shopfloor. During the manufacturing processes of a product, a variety of meta data can be derived from each working step and considered during subsequent stages of its liefycle like shipment, utilization or recycling. With upcoming regulations decided by the European Union, manufacturers must begin to react to the demand of a comprehensive circular economies by introducing technical solutions like Digital Product Passports (DPP). By associating the specific conditions of all stages in the life of a product within a digital identity, e.g., the DPP, transparency and efficiency can be increased. The Gaia-X service landscape aims at realizing federated data infrastructures, enabling robust and transparent services while considering data sovereignty. In this work, a modular and generic multi-tenant framework for utilizing DPPs within cross-company ecosystems is presented with respect to the manufacturing sector. In applying the Secret Network-blockchain for implementing the automation of DPP management processes, premises for Gaia-X compliance and therefore strengthened trust-anchors are realized. By considering details of ecosystems, as well as most interesting security threats to the proposed architecture, a holistic view of applying DPPs in the context of smart production supply chains is shown. In presenting a simple but vivid use case of the production and compilation of car wheels, the fundamental benefits of the work on hand are underlined, once more.

Published: February 2024

We describe the development and validation of a HPLC-MS/MS method to assess the pharmacokinetics and tumour distribution of fenretinide, a synthetic retinoid chemically related to all-trans-retinoic acid, after administration of a novel oral nanoformulation of fenretinide, called bionanofenretinide (BNF). BNF was developed to overcome the major limitation of fenretinide: its poor aqueous solubility and bioavailability due to its hydrophobic nature. The method proved to be reproducible, precise, and highly accurate for the measurement of the drug and the mains metabolites. The lower limit of quantification resulted 1 ng/mL. The curve range of 1-500 ng/mL and 50-2000 ng/mL, for plasma and tumor homogenate respectively, was appropriate for the analysis, as demonstrated by the accuracy between 96.8% and 102.4% for plasma and 96.6-102.3% for tumor. The inter-days precision and accuracy determined on quality controls at 3 different levels were in ranges of 6.9%-7.5% and 99.3-101.0% and 0.96-1.91% and 102.3-105.8% for plasma and tumour, respectively.

Authors: Kim Jong Hun , Choi Yeong Uk , Jung Jong Hoon , Kim Jae-Hun
Published: February 2024

In this study, a novel flexible ethanol gas sensor was created by the deposition of CoFe2O4 (CFO) thin film was on a thin mica substrate using pulsed laser deposition. Transition electron microscopy (TEM) investigations clearly demonstrated the successful growth of CFO on the mica, where a well-defined interface was observed. Ethanol gas-sensing studies showed optimal performance at 200 °C, with the highest response, 19.2, to 100 ppm ethanol. Operating the sensor in self-heating mode under 7 V applied voltage, which was corresponds to a temperature of approximately 200 °C, produced a maximal response to ethanol of 19.2. This aligned with the highest responses observed during testing at 200 °C, confirming the sensor’s accuracy and sensitivity to ethanol under self-heating conditions. In addition, the sensor exhibited good selectivity to ethanol and excellent flexibility; maintaining its high performance after bending and tilting up to 5000 times. As this is the first report on flexible self-heated CFO gas sensors, we believe that this research holds great promise for the future development of high-quality sensors based on this approach.

Published: February 2024

(1) The present study investigated the effect of orally administered Limosilactobacillus fermentum HY7302 (HY7302) on the relationship between ocular tissue and the microbiome in the corneal injured dry eye mice model. (2) 0.1% benzalkonium chloride (BAC) was applied to the ocular surface for 14 days to induce corneal injury in male Balb/c mice. During the BAC treatment period, HY7302 (1 × 108 CFU/kg/day or 1 × 109 CFU/kg/day) or omega-3 positive control (200 mg/kg/day) were administered orally (n = 8/group). To examine signaling pathways affected by HY7302 treatment, the in vitro effects of HY7302 on tight junctions and the inflammatory response were investigated in a mouse colon epithelial cell line, CMT-93. (3) BAC exposure decreased tear production, induced ocular inflammation and corneal epithelial detachment, and altered gut microbiota. However, oral administration of HY7302 restored tear secretion and decreased corneal epithelial detachment in BAC-treated corneal injury mice. Further, HY7302 alleviated corneal inflammation via modulation of matrix metalloproteinase-9 (MMP-9) expression and alterations in gut microbiota composition. (4) These findings suggest that the gut–eye axis interaction between gut microbiota and eye tissue affects disease severity in corneal injury, and that alteration of the microbiota by HY7302 could improve eye health by regulating the inflammatory response.

Authors: Paulauskas Vytautas , Paulauskas Donatas
Published: February 2024

Turning ships in port turning basins is an important and responsible operation, mainly involving the ship itself and the port tugs. Such operations involve many maneuvers that consume a lot of energy (fuel) and emit a lot of emissions. Turning basins in harbors and quay approaches are in most cases relatively shallow. The paper examines the turning of ships in port turning basins using harbor tugs, the effect of shallow depth on ship turning, energy (fuel) consumption and the generation of emissions during such maneuvers of harbor tugs. The paper presents the developed theoretical models, and the experimental results on theoretical models, which were verified on real ships and using calibrated simulators. Discussions and conclusions prepared on the basis of the research base. The use of the developed methodology makes it possible to increase shipping safety, optimize maneuvers and reduce energy (fuel) consumption when turning ships in the port and at the same time reduce the amount of fuel consumed by port tugs and reduce the number of emissions of tugs during such operations.

The most common species include 49 taxa, category II – 17 taxa, category III – 7 species, category IV–V – 2 species. The maximum similarity in species composition was noted between populations in the Zhangyr and Coneu Rivers valleys. The maximum morphometric indicators were observed among the population of the river valley. Coneu and the minima are located on the Taisoigan sands. Analysis of the age spectrum made it possible to determine that the populations in the Zhangyr and Coneu Rivers valleys are characterized as young, in the area of Imankara Mountain and on the Taisoigan sands - as stable and middle-aged.
Can Short-Term Online-Monitoring Improve the Current WFD Water Quality Assessment Regime? Systematic Resampling of High Resolution Data From Four Saxon Catchments
Authors: Benisch Jakob , Helm Björn , Chang Xin , Krebs Peter
Published: February 2024

The European Union Water Framework Directive (2000/60/EC; WFD) aims to achieve a good ecological and chemical status of all bodies of surface water by 2027. The development of an integrated guidance on surface water chemical monitoring (e.g. WFD Guidance Document No. 7/19) has been transferred into national German law (Ordinance for the Protection of Surface Waters, OGewV). For the majority of compounds, this act requires a monthly sampling frequency to assess the chemical water quality status of a surface water body. To evaluate the representativeness of the sampling strategy under the OGewV, high-frequency online monitoring data is investigated under different sampling scenarios and compared with current, monthly grab sampling strategy. About 23 million data points were analyzed for this study, three chemical parameters (dissolved oxygen, nitrate-nitrogen, chloride concentration) and discharge data were selected from four catchment of different sizes ranging from 51391 km² to 84 km² (Elbe, Vereinigte Mulde, Neiße and two stations at Lockwitzbach). In this paper we proposed short-term online-monitoring (STOM) as a sampling alternative. STOM considers the placement of online sensors over a limited duration and return interval. In general we: (I) compare the results of conventional grab sampling with STOM, (II) investigate the different performance of STOM and grab sampling using discharge data as proxy for analyzing event-mobilized pollutants and (III) investigate the related uncertainties and costs of both sampling methods. Results show, that STOM outperforms grab sampling for parameters where minimum/maximum concentrations are required by law as the probability to catch a single extreme value is higher with STOM. Furthermore, parameters showing a pronounced diurnal pattern, like dissolved oxygen, are also captured considerably better. The performance of STOM showed no substantial improvements for parameters with small concentration variability, as nitrogen-nitrate The analysis of discharge events as a proxy parameter for event-mobilized pollutants proved that the probability of capturing samples during events is significantly increased by STOM.
The Power of the Dog: Caesar of Notts and the Mourning of Edward VII
Authors: Sabatos Terri
Published: February 2024

Like his mother Queen Victoria, Edward VII kept a thriving kennel at Sandringham and developed close bonds with several of his dogs. His most well-known canine companion was Caesar of Notts, a wirehaired fox terrier who entered the royal kennels in 1903. Caesar went everywhere with Edward and their travels were often recounted in the popular press. Caesar’s most famous role, however, came after Edward’s death, when Caesar was included in the king’s funeral procession on 20 May 1910. The image of the scruffy dog following the gun carriage carrying his dead master struck a poignant chord with the public and interest in Caesar exploded. Pictures and stories featuring the dog appeared in the contemporary press, and in other texts and material objects including books, paintings, and picture postcards. Using these primary sources as well as recent animal studies scholarship, this paper establishes the significance of the king’s bond with Caesar, explains how Caesar became a symbol of the nation in mourning, and discusses the dog’s part in shaping the public memory of Edward VII by highlighting the king’s domestic attachments, and his empathy for the common people of Britain.
“Wishing to Defend Her Country”: Philippa of Hainaut, Royal Marital Partnership, and the Battle of Neville’s Cross (1346)
Authors: Schoonover Jordan Michelle
Published: February 2024

This article re-examines the chronicle accounts of Philippa of Hainaut, Queen of England, being present at the Battle of Neville’s Cross through the lens of constructing ideal queenship models. It argues that there is more evidence for Philippa’s presence than have previously been considered, including an often-overlooked account from Valenciennes. Even if this was an exaggeration of the evidence by Flemish chroniclers, the construction of Philippa’s role expands our understanding of ideal queenship in late medieval England. Philippa’s military participation is praised as a mirror to her husband’s victory at Crécy to construct an ideal of English queenship which could involve military leadership alongside motherhood and intercession. In examining the similar descriptions of the two battles provided by Froissart’s Chronicles, the article outlines how kingship and queenship were dually constructed and mutually dependent. One could not be fully realized without the other.

“Large wen” or “swelling”?
 Exploring Myths and Misconceptions about Nicholas Sander’s Description of Anne Boleyn and Its Link to Witchcraft
Authors: Soberton Sylvia  Barbara
Published: February 2024

Despite the recent surge in Anne Boleyn-themed books and articles, scholars still cannot agree on the subject of Anne and witchcraft. There are two polarising schools of thought: one is that Anne had “the physical characteristics of a witch,” based on the hostile account of Nicholas Sander, and the other that she was never “branded a witch in her own lifetime.” This essay argues that neither of these two views is correct and that there is enough compelling evidence to refute them both. It is time to return to the original source material and re-evaluate this part of the narrative of Anne Boleyn’s life.

Objectives. To assess COVID-19 and influenza vaccination rates across Indiana’s 92 counties and identify county-level factors associated with vaccination.

Methods. We analyzed county-level data on adult COVID-19 vaccination from the Indiana vaccine registry and 2021 adult influenza vaccination from the Centers for Disease Control and Prevention. We used multiple linear regression (MLR) to determine county-level predictors of vaccinations.

Results. COVID-19 vaccination ranged from 31.2% to 87.6% (mean = 58.0%); influenza vaccination ranged from 33.7% to 53.1% (mean = 42.9%). In MLR, COVID-19 vaccination was significantly associated with primary care providers per capita (b = 0.04; 95% confidence interval [CI] = 0.02, 0.05), median household income (b = 0.23; 95% CI = 0.12, 0.34), percentage Medicare enrollees with a mammogram (b = 0.29; 95% CI = 0.08, 0.51), percentage uninsured (b = −1.22; 95% CI = −1.57, −0.87), percentage African American (b = 0.31; 95% CI = 0.19, 0.42), percentage female (b = −0.97; 95% CI = −1.79, ‒0.15), and percentage who smoke (b = −0.75; 95% CI = −1.26, −0.23). Influenza vaccination was significantly associated with percentage uninsured (b = 0.71; 95% CI = 0.22, 1.21), percentage African American (b = −0.07; 95% CI = −0.13, −0.01), percentage Hispanic (b = −0.28; 95% CI = −0.40, −0.17), percentage who smoke (b = −0.85; 95% CI = −1.06, −0.64), and percentage who completed high school (b = 0.54; 95% CI = 0.21, 0.87). The MLR models explained 86.7% (COVID-19) and 70.2% (influenza) of the variance.

Conclusions. Factors associated with COVID-19 and influenza vaccinations varied. Variables reflecting access to care (e.g., insurance) and higher risk of severe disease (e.g., smoking) are notable. Programs to improve access and target high-risk populations may improve vaccination rates. ( Am J Public Health. 2024;114(4):415–423. https://doi.org/10.2105/AJPH.2023.307553 )

Experimental data show that the FGO-PEI based nanoplatform has an estimated adsorption capacity (𝘲ₘ) of ∼219 mg g⁻¹ for perfluorononanoic acid (PFNA) and can be used for 99% removal of several short- and long-chain PFAS. A comparative PFNA capturing study using different types of nanoplatforms indicates that the 𝘲ₘ value is in the order FGO-PEI > FGO > GO-PEI, which indicates that fluorophilic, electrostatic, and hydrophobic interactions play important roles for the removal of PFAS. Reported data show that the FGO-PEI based nanoplatform has a capability for 100% removal of moxifloxacin antibiotics with an estimated 𝘲ₘ of ∼299 mg g⁻¹. Furthermore, because the pore size of the nanoplatform is much smaller than the size of pathogens, it has a capability for 100% removal of Salmonella and Escherichia coli from water. Moreover, reported data show around 96% removal of PFAS, pharmaceutical toxins, and pathogens simultaneously from spiked river, lake, and tap water samples using the nanoplatform.

Authors: Liang Guibao , Xia Qiao , Zhang Lijie
Published: February 2024

Digital finance (DF) has an essential impact on improving green economy efficiency (GEE) by demonstrating environmental friendliness in promoting technological innovation and the flow of factors. Based on the panel data of 30 provinces in China from 2011 to 2020, this paper uses the super-efficiency SBM model with undesirable outputs to measure the provincial GEE. It tests the nonlinear impact of DG on green economic efficiency. Additionally, a heterogeneity analysis has been conducted. The conclusions are: (1) a significant, positive U-shaped nonlinear relationship exists between DF and GEE. The robustness test and the instrumental variable model verify that the results are still valid; (2) the results of the heterogeneity analysis illustrate that the U-shaped relationship between DF and GEE is significant in undeveloped regions. In contrast, it shows a linear promoting effect in the developed areas; (3) mechanism research demonstrates that the regional technological innovation level is an effective mechanism of the U-shaped relationship; (4) the moderating effect test establishes that environmental regulation can positively moderate the nonlinear relationship between DF and GEE. Therefore, the government can give free rein to the functions of DF to improve the efficiency of the green economy.
Gravitational Interactions of Two Small Evaporating Drops
Authors: Rother Michael
Published: February 2024

Relative trajectories are determined for a pair of water drops falling in air with radii between 2 μm and 30 μm. The droplets are small enough that diffusion dominates convection in evaporation, but significant drop inertia at low Reynolds number is considered. In addition to hydrodynamic and lubrication forces, attractive van der Waals forces and Maxwell slip are taken into account. Because the loss of mass is not uniform due to the presence of a second drop, and mass transfer and momentum transfer are effectively decoupled, the droplet position needs to be assessed. Three outcomes are compared. The isolated drop result for both droplets is employed as a base case, since the mass loss is constant over each drop surface. Alternatively, the bispherical coordinate solution for two evaporating drops is applied, with the drop positions 1) fixed by the hydrodynamics or 2) allowed to move based on the nonspherical mass loss. In all three cases, evaporation leads to weaker inertial effects and stronger hydrodynamic effects. The single sphere model has the largest drop gap, followed by the bispherical coordinate solutions with a fixed and movable center, respectively. Critical horizontal offsets for coalescence are also calculated with a finite vertical offset. With both attractive molecular forces and slip, all three approaches to evaporation lead to similar results, making the choice of method nearly inconsequential. Moderate agreement between previous experiments and an approximate, generalized form of the current theory is obtained for the evaporation rate of falling drops.

Published: February 2024

MiRNAs are currently being studied for their biomarker potential in many diseases, including Alzheimer’s disease (AD). Here, we explored the biomarker potential of miR-502-3p/miR-501-3p in cerebrospinal fluid (CSF) exosomes in accordance with amyloid plaques and neurofibrillary tangles (NFTs) severity in AD brain. The miR-502-3p/miR-501-3p expression were analyzed in CSF exosomes isolated from AD and unaffected controls (UC) samples. The miR-502-3p/miR-501-3p levels were examined with CSF Aβ1–40, Aβ1–42, Tau, p-Tau levels and with neuropathology of AD brain. The miR-502-3p/miR-501-3p expression levels were upregulated in AD CSF exosomes relative to UC CSF exosomes. MiR-502-3p level was positively correlated with CSF Aβ1–40 level while miR-501-3p was positively correlated with CSF p-Tau levels. Expressions of miR-502-3p/miR-501-3p were significantly associated with severity of amyloid plaques and NFTs in the entorhinal cortex, hippocampus, amygdala, middle frontal gyrus, inferior parietal lobule, and superior temporal gyrus. Therefore, miR-502-3p/miR-501-3p panels could potentially be useful biomarkers for AD in future.

Authors: Khah Mohammad Malakouti , Esmailifar Sayyed Majid , Saadat Sepehr
Published: February 2024

In this study, a novel multirotor configuration has been developed, which utilizes a coaxial counter-rotating propeller with a large diameter at the center and four propellers with smaller diameters on four arms in an X configuration. The research pursues two main objectives. The first objective is to establish a development method for multirotors based on the well-known V-diagram approach in system development. The proposed method enables the design team to analyse and evaluate the multirotor at each stage of the design process, from the system to the component level, and improve the design with greater speed and accuracy. Additionally, the proposed approach can be integrated with various optimization methods, if necessary, to achieve an optimal design. The second objective is to provide the proof-of-concept of the novel multirotor configuration. This objective is pursued across different evaluation sections, from evaluating individual components to fully evaluating the multirotor, to assess the performance of this novel configuration and identify its advantages and disadvantages. The results of various evaluations demonstrate the proposed development process's practicality and proves that the novel configuration is operational and competitive with conventional multirotors in various applications.

Published: February 2024

Objective
This study aimed to determine associations between hypothyroidism during pregnancy and selected maternal and neonatal outcomes.
Methods
A retrospective, cohort study was conducted between January 2018 and December 2020 at the two main tertiary hospitals in Muscat, Oman. A total of 408 Omani pregnant women aged 18–45 years were included. Data from electronic medical records were compared between women with overt or subclinical hypothyroidism (n = 201; the exposed group) and those with normal thyroid function (n = 207; the matched unexposed group) to determine associations with selected outcomes.
Results
In terms of maternal outcomes, no significant differences were observed between exposed and unexposed groups with regards to the risk of gestational diabetes mellitus, pregnancy-induced hypertension, or pre-eclampsia (P > 0.05). However, pregnant women with hypothyroidism were twice as likely to exhibit iron deficiency anemia at delivery compared to women with normal thyroid function (relative risk [RR]: 2.22, 95% confidence interval [CI]: 1.68–2.94; P < 0.001). Regarding neonatal outcomes, newborns born to mothers with hypothyroidism were less likely to be premature (RR: 0.83, 95% CI: 0.23–3.06), have low birth weight (RR: 0.86, 95% CI: 0.46–1.55), and exhibit macrosomia (RR: 0.52, 95% CI: 0.096–2.81) or abnormal cord TSH levels (RR: 0.21, 95% CI: 0.01–4.31); however, these associations were not statistically significant (P > 0.05).
Conclusion
Pregnant women with hypothyroidism were not found to be at increased risk of adverse maternal and neonatal outcomes compared to those without hypothyroidism. These findings could be attributed to the fact that most of the studied pregnant women with hypothyroidism were already receiving thyroxine replacement therapy, thereby achieving euthyroid status from a clinical and biochemical standpoint.
Analysis of ionospheric anomalies before earthquakes with Mw6.5 and above in Japan during 2011-2022
Authors: Li Zhen , Tao Zhen , Cao Lianhai
Published: February 2024

In order to study the seismic-ionospheric coupling relationship, this paper selects window values based on wavelet power spectrum method, and obtains the 27-day periodicity of wavelet power spectrum in the full time domain that passes 95% significance test. Then, sliding quartile method is used to analyze the earthquakes above Mw6.5 in Japan from 2011 to 2022, which exclude hybrid effects. Sunspot number (SSN), 10.7cm radio flux (F10.7), solar wind velocity (Vsw), storm ring current index (DST), and global Geomagnetic activity index (KP) are excluded as interference terms to eliminate the influence of solar and geomagnetic activity. According to the lithosphere-atmosphere-ionospheric coupling mechanism (LAIC) and global TECmap, the abnormal changes on the 29th day before the earthquake (February 15, 2022), which do not conform to the previous research rules, are analyzed to prove that TEC anomalies caused by earthquakes. The statistical analysis of ionospheric TEC anomalies shows that the magnitude of earthquake is positively correlated with the amplitude of TEC anomalies, and the occurrence time of ionospheric anomalies tends to lag as the magnitude increases.

Published: February 2024

Background
Various factors can cause vascular endothelial damage during cardiovascular surgery (CVS) with cardiopulmonary bypass (CPB), which has been suggested to be associated with postoperative complications. However, few studies have specifically investigated the relationship between the degree of vascular endothelial damage and postoperative acute kidney injury (pAKI).
The objectives of this study were to measure perioperative serum syndecan-1 concentrations in patients who underwent CVS with CPB, evaluate their trends, and determine their association with pAKI.
Methods
This was a descriptive and case‒control study conducted at the National University Hospital. Adult patients who underwent CVS with CPB at a national university hospital between March 15, 2016, and August 31, 2020, were included. Patients who were undergoing preoperative dialysis, had preoperative serum creatinine concentrations greater than 2.0 mg dl-1, who were undergoing surgery involving the descending aorta were excluded. The perioperative serum syndecan-1 concentration was measured, and its association with pAKI was investigated.
Results
Fifty-two patients were included. pAKI occurred in 18 (34.6%) of those patients. The serum syndecan-1 concentration increased after CPB initiation and exhibited bimodal peak values. The serum syndecan-1 concentration at all time points was significantly elevated compared to that after the induction of anesthesia. The serum syndecan-1 concentration at 30 min after weaning from CPB and on postoperative day 1 was associated with the occurrence of pAKI (OR=1.10 [1.01 to 1.21], P=0.03]; OR=1.16 [1.01 to 1.34], P=0.04]; and the cutoff values of the serum syndecan-1 concentration that resulted in pAKI were 101.0 ng ml-1 (sensitivity=0.71, specificity=0.62, area under the curve (AUC)=0.67 (0.51 to 0.83)) and 57.1 ng ml-1 (sensitivity=0.82, specificity=0.56, AUC=0.71 (0.57 to 0.86)). Multivariate logistic regression analysis revealed that the serum syndecan-1 concentration on postoperative day 1 was associated with the occurrence of pAKI (OR=1.02 [1.00 to 1.03]; P=0.03).
Conclusion
The serum syndecan-1 concentration at all time points was significantly greater than that after the induction of anesthesia. The serum syndecan-1 concentration on postoperative day 1 was significantly associated with the occurrence of pAKI.
