Structural Characteristics of Games and Online Consumer Behaviour: an Analysis in the Italian Gambling Market
Authors: Calvosa Paolo
Published: October 2022

The rapid growth of e-commerce over the last years has sparked a stream of research that has analysed the impact of Internet retailing on consumer behavior. This paper intends to offer a contribution, in the field of management studies, to the understanding of the reasons why the level of e-commerce use in a specific service sector, that of gambling, is different for different categories of services offered. In particular, the aims of this work is to analyze how the nature and specific characteristics of the different types of games could influence the customers’ decisions in terms of choice between digital and physical purchase channels. Thus, consequently, impacting the degree of development of online sales for the different types of gambling. This analysis is carried out in the context of one of the main national legal gambling markets in the world, the Italian one, in which Internet gambling is now a mature and consolidated industry. The results of the analysis have shown that for most of the traditional betting categories offered in Italy – Lotteries, Lotto, Totalisator numerical game, Bingo, Virtual bets – the nature and the distinctive characteristics of the game give little emphasis to the potential benefits usually associated with online gambling, and this has determined a reduced development of online sales. Only for Sports-based games (sports betting) the nature and characteristics of the game seem to have exploited a number of significant benefits that Internet gambling offers to players. This helps to understand why betting websites for Sports-based games have become the main channel of purchase in Italy. These results have interesting managerial implications for gambling operators, as discussed in this work.

More efficient clinical trials in pancreatic cancer: develop better treatment options, faster
Authors: Rosenzweig Allison , Moravek Cassadie , Matrisian Lynn M.
Published: October 2022

Clinical development of new treatment options for patients with pancreatic cancer has been slow and expensive and resulted in few effective therapies. With a dismal five-year survival rate of 11% in the U.S., pancreatic cancer remains the third leading cause of cancer-related deaths and is poised to move to second by 2030. Standard clinical trials typically compare one investigational treatment to one standard of care, encompass one phase of clinical investigation at a time, and treat one patient population. Accrual and data analysis are often very slow, and unfortunately, the vast majority of clinical trials targeting pancreatic cancer patients are unsuccessful. More efficient clinical trial designs can include combining phases I and II or phases II and III, and trials that involve a master protocol approach can also answer multiple clinical questions simultaneously. These modern clinical trial designs can allow a faster, more efficient and cost-effective approach to testing investigational therapies in patients with pancreatic cancer and, most importantly, fewer patients may be required to determine the efficacy of treatment. Herein we summarize some of the recent innovative clinical trials in pancreatic cancer to provide meaningful data toward developing new treatment options to benefit patients with a dismal disease like pancreatic cancer.

Judicialising party primaries : contemporary developments in Nigeria
Authors: Ihembe Martin , Isike Christopher
Published: October 2022

This article explores the judicialisation of party primaries in contemporary Nigeria, which is a defining feature of the country’s electoral politics. Since the inception of the Fourth Republic, the lack of internal democracy within the parties has been the source of protracted crises during nomination, and this often gravitates to the serenity of the court(s). Dominant disquisitions in legal theory contend that disputed primaries are internal party affairs; hence, they are non-justiciable. Drawing on primary and secondary data – YouTube interviews, the Constitution, the Electoral Act, judicial ruling, media reports, and personal observation – this article argues that to the extent that political parties are juridical entities, disputed primary elections are justiciable, hence a legal question to be resolved by the judiciary. To validate our argument, the article draws on Raphael’s (1970) notion of universal and compulsory jurisdiction. Our enquiry reveals that the failure of the internal mechanisms of the parties to resolve disputed party primaries accounts for aggrieved aspirants’ reliance on legal redress. While this approach has been questioned from a legalistic point of view, the constitutionality of seeking legal redress has its provenance in the change of legal regime regulating party primaries, which has shaped, reshaped, and positively impacted electoral democracy in Nigeria.
Immune Sexual Dimorphism During Acute Infection by Toxocara canis: A Novel Approach for an Old Infection
Authors: Río-Araiza Víctor Hugo Del , Alcalá-Canto Yazmín , Garay-Canales Claudia , Morales-Montor Jorge
Published: October 2022

Toxocara canis is a helminth parasite with importance in public and veterinary health. Although different studies have evaluated the immune response, to date there are no studies where it is analyzed from the point of view of sexual dimorphism. At 7 days of infection, female rats had a higher number of larvae in the liver, while male rats had them in the lungs. The percentages of immune cells were evaluated, and in most cases, no significant differences were observed. Regarding the cytokines production, infection can generate a decrease in Th1 such as IL-1β in both sexes and IL-6 only in females. In the case of Th2, IL-4 increases only in infected males and IL-5 increases in males and decreases in females due to the effect of infection. IL-10 also decreases in both sexes as a consequence of the infection and TGF-β only in females. Finally, the infection generates the production of antibody against the parasite, however, their quantity is lower in females. Thus, this study demonstrates that Toxocara canis infection is dimorphic and affects females more than males. This is due to a polarization of the inadequate immune response, which is reflected as a higher parasite load in this sex.

Authors: Ivanisenko Timofey V , Demenkov Pavel S , Kolchanov Nikolay A. , Ivanisenko Vladimir A.
Published: October 2022

The body of scientific literature continues to grow annually. Over 1.5 million abstracts of biomedical publications were added to the PubMed database in 2021. Therefore, developing cognitive systems that provide a specialized search for information in scientific publications based on subject area ontology and modern artificial intelligence methods is urgently needed. We previously developed a web-based information retrieval system, ANDDigest, designed to search and analyze information in the PubMed database using a customized domain ontology. This paper presents an improved ANDDigest version that uses fine-tuned PubMedBERT classifiers to enhance the quality of short name recognition for molecular-genetics entities in PubMed abstracts on eight biological object types: cell components, diseases, side effects, genes, proteins, pathways, drugs, and metabolites. This approach increased average short name recognition accuracy by 13%. The new ANDDigest version (01.2022) has a web interface and is freely available to users at https://anddigest.sysbio.ru/.
Implementation of a Modular Distributed Fault-tolerant Controller for MMC Applications
Authors: Isik Semih , Burugula Vasishta , Alharbi Mohammed , Azidehak Ali , Bhattacharya Subhashish
Published: October 2022

Centralized control algorithm limits the hardware flexibility of a Modular Multilevel Converter (MMC). Therefore, industrial MMC applications have started adopting distributed control structures. Even though distributed controller reduces a single point of failure risk compared to the centralized controller, the failure risk of the entire control systems increases due to the number of local controllers. However, the distributed controller can be programmed in such a way as to bypass the faulty local controller and take care of the power modules with the adjacent local controllers. This paper implements a modular distributed fault-tolerant controller for a scaled laboratory MMC prototype. Experimental results show that an MMC can operate without interruption, even under two local controller failures. Besides, the experimental results are verified with the Opal-RT, a real-time simulator with the same controller in a Control Hardware in Loop (CHIL) environment.
A Taxonomy of Elementary Behavior Modes for Novice Modelers
Authors: Schaffernicht Martin , Hartwig Johannes
Published: October 2022

This article addresses a challenge modeling novices face in model conceptualization: the recognition of behavior modes. Despite behavior modes being at the heart of system dynamics modeling, there is no unifying taxonomy for them, making them harder to learn for beginners. The article proposes criteria a taxonomy should satisfy, critically reviews previous taxonomies in the literature, and then introduces a new consistent taxonomy based on slope and curvature with mode names that refer only to visual cues and free of references to prior mathematical or domain-specific knowledge. Evidence from an exploratory experiment suggests that novices actually have difficulties classifying curves when using previous taxonomies. Links from these elementary modes to analogous terms in other taxonomies in diverse disciplines allow this taxonomy to be related to other ones. The article concludes by mentioning relevant limitations and future steps.
Biodiversity and Human Health: A Scoping Review and Case Studies on Underrepresented Linkages
Authors: Robinson Jake , Breed Andrew , Camargo Araceli , Redvers Nicole , Breed Martin
Published: October 2022

Mounting evidence supports the connections between exposure to environment types––such as green spaces and biodiversity––and human health. However, the mechanistic links that connect biodiversity (the variety of life) and human health, plus the level of supporting evidence, are less clear. Here, we undertook a scoping review to map the links between biodiversity and human health and summarise the levels of associated evidence using an established weight of evidence framework. Distinct from other reviews, we provide additional context regarding the environment-microbiome-health axis, evaluate the environmental buffering pathway (e.g., biodiversity impacts on air pollution), and draw upon expert opinion to provide case studies on three underrepresented linkages. The case studies include (1) biodiversity and Indigenous Peoples’ health, (2) biodiversity and urban social equity, and (3) biodiversity and COVID-19. We observed a moderate level of evidence to support the environmental microbiota-human health pathway and a moderate-high level of evidence to support broader nature pathways (e.g., green space) to various health outcomes, from stress reduction to enhanced wellbeing and improved social cohesion. However, studies of broader nature pathways did not typically include specific biodiversity metrics, indicating clear research gaps. Further research is required to understand the connections and causative pathways between biodiversity (e.g., using metrics such as taxonomy, diversity/richness, structure, and function) and health outcomes. There are well-established frameworks to assess the effects of broad classifications of nature on human health. These can assist future research in linking biodiversity metrics to human health outcomes. Our case studies on underrepresented linkages highlight the roles of biodiversity and its loss on urban lived experiences, infectious diseases, and Indigenous Peoples’ sovereignty and livelihoods. More research and awareness of these socioecological interconnections are needed.

Published: October 2022

Carbon dots (CDots) are nanomaterials that can be applied as a heavy metal ion sensor. CDotss ware synthesized from corncobs which are abundant and underutilized. This study aims to determine the effect of variations in the concentration of corncobs on optical properties of CDots and their application as  Fe3+ ion sensors. CDots were synthesized with variations of corncobs’ mass 5, 10, 15, and 20 g and variations in metal ion concentrations 10-7, 10-6, 10-5, 10-4, and 10-3 M. The success of CDots synthesis was indicated by luminescence green when exposed to UV light. UV-Vis characterization showed that the greater the concentration of CDots could cause a shift in the absorbance peak towards longer wavelengths and peaks at wavelengths of 290, 291, 295, 298, and 323 nm, respectively. Photoluminescence (PL) characterization showed CDots emission peaks at 511, 504, 503, and 495 nm. The greater the concentration of CDots can cause a shift in the emission peak towards a shorter wavelength and increase the intensity. The PL characterization can identify the presence of Fe3+ metal ions with a wavelength shift that indicates a change in the CDots structure. The synthesis of CDots from corncobs have great potential to be applied as sensors.

Published: October 2022

In recent years, advances in CMOS imagers and AI have rapidly expanded the application fields of image processing. Spatial resolution, sensitivity, dynamic range, etc. for devices have dramatically improved, while various recognition functions have been implemented with the introduction of learning-based information processing, making progress day by day. However, the temporal resolution or temporal dynamics of an image has been limited to the video rate level of processing, because image processing has been required to realize the functions of the human eye. In the case of processing for high-speed moving objects or controlling machine dynamics as machine eyes, rather than processing in the range visible to the human eye, high-speed vision, i.e., high-speed image processing in a bandwidth that covers the dynamics of the object, and a system that utilizes such processing, are required. This special issue summarizes such advanced research on high-speed vision, highlighting its current status and future development in the areas of devices, systems, and application developments.

High-speed vision has entered a new era, as the basic technology and various applications have been developed and new functions are being added one after another. We hope that this timely special issue will help its readers grasp this major technological trend and create new system values.

Currently, high-speed vision based on parallel processing exists, and its various applications as high-speed intelligent systems have been proposed and implemented. The basic goal of high-speed vision is to realize vision capabilities and systems that operate at speeds necessary for intelligent systems, in which intelligence operating at the speed inherently required by the application system is achieved. This paper described the vision chip and parallel image processing architectures, presented outlines of system architectures, image-processing algorithms, and related peripheral technologies; described the concepts required to configure high-speed intelligent systems, such as hierarchical parallel distributed architecture, parallel decomposition, orthogonal decomposition, dynamics matching, latency minimization, high-speed 3D shape measurement, active vision, tracking vision, dynamic compensation, and dynamic projection mapping; and discussed a wide range of application systems in a systematic manner.

Our research group has developed an air hockey robot with high-speed vision capable of visual recognition at 500 Hz, which exceeds that of humans. Although this robot uses high-speed vision to increase its reaction speed and improve its performance, it has a low speed to compete with humans because its hand speed is still not sufficiently fast. In this study, a high-speed wrist rotation mechanism using a direct drive motor was introduced to the air hockey robot to improve the hitting speed through the snapping motion of the wrist. Furthermore, we developed a hitting motion algorithm that utilizes high-speed visual feedback. The effectiveness of the proposed system was verified experimentally. The proposed system exhibits an improved motion performance.

Making robots capable of pouring can be useful in both service and industrial applications. Considering the importance of controlling liquid vibration in mixing chemical reagents and other industrial applications, we investigated in the this study robotic pouring with the aim of controlling liquid vibration, more specifically, the beer-foam ratio during beer pouring. We propose a vision-based measurement method that can measure the liquid volume with an error of less than 5% in real time. Besides, together with a proposed robot pouring controller, we develop a robot pouring system that can control ratio of beer-foam volume with an error of less than 5% during pouring. The flexibility of the developed system was also demonstrated through experiments using different types of container and beer.

Object tracking and pose estimation have always been challenging tasks in robotics, particularly for rotating objects. Rotating objects move quickly and with complex pose variations. In this study, we introduce a marker-based tracking and pose estimation method for rotating objects using a high-speed vision system. The method can obtain pose information at frequencies greater than 500 Hz, and can still estimate the pose when parts of the markers are lost during tracking. A robot catching experiment shows that the accuracy and frequency of this system are capable of high-speed tracking tasks.

In recent years, it is required to acquire three-dimensional information at high speed in various fields. Previously, a structured light field (SLF) method for high-speed three dimensional measurement in 1 ms was proposed by our group. However, the SLF method has a drawback of worse depth estimation error by several tens millimeters. In this paper, a novel method to generate SLF with two projectors placed in parallel is proposed. This arrangement could produce bigger pattern change depending on the depth and made more precise estimation possible. The depth estimation experiments for precision evaluation and dynamic projection mapping experiment successfully demonstrated precise depth estimation with the error of several millimeters and high-speed estimation within 1 ms, though the measurement range was limited to approximately 100 mm.

It is important to miniaturize robot systems while maintaining advantages such as high responsiveness and functionality for human-machine interactions and for achieving integration with other robotic systems such as drones. In this research, we focused on the miniaturization of a high-speed visual feedback system, and developed a “portable saccade mirror,” which is a system that can realize active target tracking using 1000 Hz image capturing, processing, and feedback actuation with only 3 ms latency in a handheld device. By using a three-dimensionally-stacked vision chip, the proposed system achieved high speed, low latency, low power consumption and compact size, and therefore, can be considered as a good example of a miniaturized high-speed visual feedback system. In this study, we evaluated the performance of the proposed system in comparison with the conventional optical gaze controller, and demonstrated some applications, such as tracking field scope and panorama target scanning.

High-frame-rate visual feedback has been proven effective for projection mapping on quickly moving targets. However, the quantitative conditions of frame rates have not been elucidated. In particular, considering that the human dynamic visual acuity generally declines as the moving target velocity increases, it may be argued that the tracking accuracy required for projection mapping on moving targets can be lower than that required for fixed targets. To examine the above-mentioned conditions of frame rates, this study compares them based on two types of projection mapping systems having equivalent relative movements to each other: projection mapping from a fixed projector/camera system to a moving target and projection mapping from a moving projector/camera system to a fixed target. We examined the effects of the target movements by having stationary observers visually recognize and evaluate them. Using the weighted up-down method, we measured the frame time that provides a just noticeable difference (JND) to the projection mapping. We found that when the visual feedback is generated at a frame time of 2 ms, the frame time that provides a JND is 3.72 ms on average for fixed targets and 3.94 ms on average for moving targets: a 1%-level significant difference. Taking the individual differences and experimental errors into account, this is not a very large variation. This suggests that, in projection mapping to moving targets, we should realize a tracking accuracy as precise as that in projection mapping to fixed targets.

Fundus images contain extensive health information. However, patients hardly obtain their fundus images by themselves. Although glare-free infrared (IR) imaging enables easy acquisition of fundus images, it is monographic and challenging to process in real-time in response to high-speed and involuntary fixational eye movement and in vivo blurring. Therefore, we propose applying our IR color technology and providing clear fundus images by high-speed tracking of involuntary fixational eye movements and eliminating in vivo blurs by deconvolution. We tested whether the proposed camera system was applicable in medical practice and capable of medical examination. We verified the IR color fundus camera system could detect ophthalmological and lifestyle-related diseases.

We developed a simple application for detecting user contact and changing the color of an object to measure the latency of our aerial interface system.
The Paradoxes Produced by the Different Ways of Determining the Rapidity of Motion in the Anonymous Treatise De sex inconvenientibus
Authors: Rommevaux-Tani Sabine
Published: October 2022

The anonymous treatise De sex inconvenientibus is a good example of the calculatores’ approach when dealing with motion. It is organized around four main questions relating to the determination of rapidity in four kinds of changes, i.e. in the generation of substantial forms, in alteration, in increase, and in local motion. In some arguments the author points out the paradoxes to which the two ways of determining the rapidity of a motion can lead: rapidity is determined by the effect produced (the degree of quality generated, the space covered, etc.) or it results from the ratio between the moving power and the resistance of the mobile or patient. While this twofold approach to determining rapidity appears in the majority of calculator texts, the two points of view – the analysis according to its effects and the analysis according to its causes – have rarely been confronted.
LOAN PORTFOLIO COMPOSITION OF ISLAMIC AND CONVENTIONAL BANKS PRE- AND POST-COVID-19 PANDEMIC? CASE OF INDONESIA

Published: October 2022

This study investigates how the Covid-19 pandemic has affected the loan portfolio composition of Indonesian Islamic and conventional banks. By using a sample of 108 conventional and 9 Islamic banks, we find that conventional banks issued more consumption loans during the sample period. On the contrary, Islamic banks granted more investment loans than consumption loans. In addition, given limited support from the central bank, Islamic banks still increased their contribution to investment loans portfolio more rapidly during the COVID-19 pandemic. These results support the view that Islamic banks provide funding to long-term investment projects and may contribute more to sustainable economic growth. This finding could have policy implications for both Islamic banks and the government. Despite the fact that Islamic banking is in its infancy in Indonesia, it provides funding for the real economy. Regulators may assist the Islamic banking sector in developing risk management capacity in various sectors, including agriculture, manufacturing, trading, distribution, hotels, and restaurants. Furthermore, implementing a well-integrated policy framework that includes monetary, fiscal, and financial services can also assist in optimizing the momentum of economic recovery after the pandemic despite global supply disruptions, the Russian-Ukraine war, and climate change.

This research investigates how Islamic rural banks performed during the Covid-19 outbreak and how diversification is associated with the performance of the banks. Islamic rural banks provide a unique setting because they serve limited customers in a specific region in Indonesia, different from national commercial banks that accommodate all types of customers in all regions. To investigate this issue, we employ panel data of 164 Islamic rural banks dispersed across 23 provinces in Indonesia from 2020q4-2021q3. We find that covid-19 is negatively associated with the profitability of Islamic rural banks, implying that covid 19 has affected all sectors, including banks with niche markets such as Islamic rural banks. We also find that diversification is negatively related to the Islamic rural banks’ performance. This finding suggests that instead of expanding their business scope, Islamic rural banks should focus on their main business activity because their non-financing income is adversely related to their performance. Our finding suggests that policymakers effectively monitor Islamic rural banks to remain focused on their main business activity.

Authors: Demir Halil Ibrahim , Dervis Suraka
Published: October 2022

With an annual passenger capacity of more than 4 billion and a rapidly increasing number, air transport is the undisputed leader among other travel options for long-distance traveling. There are unique airline connections between more than 20 thousand cities in the world. Despite this, many passengers fly via connecting as there are no direct flights from many cities to many cities or because direct flights are sometimes not economical or common. Since passengers do not like to wait in transfers, passengers are lost to other flights and airline companies if the airline does not have a suitable flight at the appropriate time for the transfer. Arrival and departure synchronization is vital at major hub airports and major airlines. In this study, the synchronization of arrival and departure flights is solved for Istanbul airport, an important hub airport worldwide, using data from a prominent airline company. Three metaheuristic methods, Evolutionary Strategies (ES), Modified Discrete Particle Swarm Optimization (MDPSO), and Random Search (RS) were used, and the results were compared with the original plan (OP). ES and MDPSO were found to be promising solution methods, and they provided substantially increased acquired passengers during connecting flights.
Border-collision bifurcation route to strange nonchaotic attractors in the piecewise linear normal form map
Authors: Zhao Yifan , Zhang Yongxiang
Published: October 2022

A new route to strange nonchaotic attractors (SNAs) is investigated in a quasiperiodically driven nonsmooth map. It is shown that the smooth quasiperiodic torus becomes nonsmooth (continuous and non-differentiable) due to the border-collision bifurcation of the torus. The nonsmooth torus gets extremely fractal and becomes a strange nonchaotic attractor and it is termed the border-collision bifurcation route to SNAs. A novel feature of this route is that SNAs are abundant and the size of SNAs makes up about 40% of the given regions. These SNAs are identified by the Lyapunov exponents and the phase sensitivity exponents and they are also characterized by the singular-continuous spectrum and distribution of finite-time Lyapunov exponents. The distribution of local Lyapunov exponents has its maximum at a relatively small negative value, which contributes largely to lead to the abundance of SNAs.
Analyzing the influence of publishing a list of resource-exhausted city with spatial difference-in-differences model: evidence from city-level data in China.
Authors: Peng Yiwen
Published: October 2022

Promoting the carbon efficiency is an accepted topic in China’s sustainable development against the background of carbon neutrality. After the State Council announced 69 resource-exhausted cities, Chinese government has strengthened policy and funds support to set up a long-term mechanism of sustainable development. This paper utilizes a spatial difference-in-differences (SDID) method to investigate the policy effect in those resource-exhausted cities and their neighboring cities, with city-level data during 2004–2016. Then we find a positive feedback of supporting policy on carbon performance in both local regions and adjacent regions. Furthermore, we find that wage distortion could account for carbon performance improvement. Our results could provide evidence and implications for realizing the low-carbon economy in China.

Authors: Almisned Faisal
Published: October 2022

Composites are important materials and can be produced adding different types of materials on it. These are used in different kind of purposes and also radiation shielding purposes. In this study composites where SiC and TiC added, were produced and radiation shielding performance were investigated. The produced composites were formulated as (95-x) Al–5SiC–xTiC where x = 0, 5,10,15,20 (wt%). The results show that by increasing the TiC rate on composite from S-0 to S-20, the ascending trend is observed for the linear attenuation coefficient (LAC, cm− 1) of the studied composites, and the best shielding performance is seen for S-20.

In view of the fact that the leakage of small holes in the buried CO2 pipeline is not easy to be detected, which leads to the problem of inability to accurately trace the source of the pipeline repair in the later stage. This paper designs and establishes a buried CO2 pipeline leak simulation experiment system and conducts experiments on small-hole leaks in buried CO2 pipelines to investigate the changes in soil temperature around the CO2 pipeline leaks. The results showed that the type of movement of CO2 in porous media after it is released from the leak is "funneling". At a distance of about 50 mm from the horizontal, the temperature difference in the horizontal surface is smallest at the 50 cm closest to the vertical distance of the leak, while at a distance of 225 mm from the horizontal, the temperature difference in the horizontal surface is largest at the 70 cm farthest from the vertical distance of the leak. The research results can provide a theoretical basis for the later development of technologies that can quickly locate the leakage points of buried CO2 pipelines and accurately determine their leakage status.
Inverse relationship between dietary fiber intake and environmental exposure to acrylamide
Authors: Gong Huanhuan , Liao Shengen
Published: October 2022

Dietary fiber intake was thought to decrease some environmental pollutants exposure by increasing gastrointestinal excretion. While diet is considered the major source of exposure to acrylamide (AA), and the impact of dietary fiber intake on acrylamide (AA) exposure is still unknown. We analyzed the associations between dietary fiber intake and AA hemoglobin biomarkers [hemoglobin adducts of acrylamide (HbAA) and glycinamide (HbGA) and sum of HbAA and HbGA (HbAA + HbGA)] among 3448 US adults who participated in the National Health and Nutrition Examination Survey (NHANES) 2013–2016. Multivariable linear regression and cubic spline models were conducted to estimate the associations between energy-adjusted fiber intake and AA hemoglobin biomarkers. Energy-adjusted fiber intake had a strong inverse and J shaped association with AA hemoglobin biomarkers. In the fully adjusted linear regression model, compared with participants in the lowest dietary fiber quantile, the adjusted percent change with 95% confidence intervals (CIs) in HbAA for the highest dietary fiber quantile was − 19.7% (-26.7%, -13.1%); for HbGA, it was − 12.2% (-18.9%, -4.9%), and for HbAA + HbGA, it was − 17.3% (-23.7%, -10.4%). Associations between higher dietary fiber intake and lower levels of environmental exposure to acrylamide hemoglobin biomarkers suggest the need to increase dietary fiber intake.

Objective: This study was to investigate the diagnostic value of quantitative parameters of dual-energy computed tomography (CT) for diagnosing lymph nodes (LNs) metastasis in papillary thyroid cancer (PTC).
Methods: PubMed, Cochrane, Embase, Web of Science, China Biology Medicine disc, WangFang, VIP, and China National Knowledge Infrastructure databases were searched up to April 20, 2022. Studies that evaluated the diagnostic value of dual-energy CT for detectingLNs metastasis in PTC patients were included. The standardized mean difference (SMD) and 95% confidence interval (CI) were used to assess the diagnostic value of quantitative parameters based on dual-energy CT for LNs metastasis in PTC. The publication bias and sensitivity analysis were performed.
Results: Twelve studies involving 1,522 PTC patients were included in this study. The iodine concentration (IC) in the venous phase (SMD: 0.33, 95% CI: 0.06 to 0.60, P=0.015), normalized iodine concentration (NIC) in venous phase (SMD: 0.15, 95% CI: 0.12 to 0.19, P<0.05), NIC in arterial phase (SMD: 0.22, 95% CI: 0.16 to 0.28, P<0.05), and the slope of the energy spectrum curve (λHU) in arterial phase (SMD: 0.99, 95% CI: 0.59 to 1.40, P<0.05) were associated with LNs metastasis in PTC.
Conclusion: The parameters based on the dual-energy CT showed diagnostic value in diagnosing LN metastasis in PTC patients which may serve as a promising tool for the diagnosis of LN metastasis in PTC.
