Mesurer l’impact économique local des établissements d’enseignement supérieur français : une analyse critique
Authors: Quiquerez Guillaume
Published: September 2023

En l’espace de quelques années, des dizaines d’universités et de grandes écoles françaises ont entrepris d’étudier leur impact économique local. Ces études posent de nombreux problèmes, parfois rédhibitoires. D’un point de vue méthodologique, on ne sait pas mesurer les conséquences économiques à long terme de la formation, tandis qu’aucun consensus ne se dégage sur la méthode permettant de mesurer l’impact régional des dépenses (critique interne). De plus, nous montrons que l’usage du raisonnement contrefactuel sur lequel se fondent les résultats affichés est illégitime. Il y a donc une mystification, que nous interprétons comme le résultat de la véritable fonction de ces travaux, qui n’est pas d’apporter une connaissance mais de persuader de la rentabilité des universités dans un but performatif (critique externe).

Les données ont été collectées à travers une enquête par questionnaire auprès des chefs d’entreprise. La validation des résultats était faite à l’aide du logiciel SmartPLS 3. Les résultats indiquent que l’intention de clôture des contrats de sous-traitance partenariale avec des sous-traitants locaux est mobilisée par la création d’une valeur ajoutée, l’amélioration et l’apprentissage organisationnel.
Le rôle de la culture et de la structure organisationnelles dans la servicisation : une étude longitudinale
Authors: Peillon Sophie , Dubruc Nadine
Published: September 2023

Cet article s’intéresse au rôle que jouent la culture et la structure organisationnelles dans la servicisation des entreprises industrielles. Il mobilise une approche qualitative et analyse les caractéristiques de la culture et de la structure organisationnelles d’une ETI, dans laquelle la stratégie de service a amené un développement important des activités de service. Nous montrons notamment que le développement des activités de service par les entreprises industrielles ne suppose pas nécessairement qu’elles abandonnent leur culture orientée produit, ni qu’elles créent une structure dédiée aux services.

Après une étude qualitative auprès de 12 dirigeants, une étude quantitative fut menée auprès de 253 dirigeants. Les résultats montrent que l’orientation-client influence positivement la performance commerciale et que le management des forces de vente y joue un rôle médiateur partiel.
Les exigences en matière de développement durable dans la gestion d’une entreprise d’un pays en voie de développement : Entre discours déontique et action délibérée – Une étude de cas
Authors: Laré Amandine , Wehbi Sleiman Manal , Martinez Fabien
Published: September 2023

Cet article analyse le discours des dirigeants du Port Autonome de Lomé (Togo) sur la gestion des enjeux du développement durable. A travers cette étude qualitative, nous démontrons que, bien que faisant face à des contraintes de développement majeures, le port met en exergue les dimensions humaines, stratégiques et environnementales de ses activités. Le discours des dirigeants vise essentiellement à expliquer l’action menée dans une dynamique de changement et de progrès. Cette emphase sur le progrès se retrouve tant au niveau discursif que performatif, démontrant ainsi que les discours managériaux dits ‘déontiques’ peuvent se traduire en actions concrètes et délibérées en faveur du développement durable.

L’article procède à un examen des entraves à la circulation de l’information durant la Grande Guerre dues aux difficultés matérielles et à la censure. Elles ont eu pour effet de rendre suspectes les informations, même véridiques. Leur contrôle par les pouvoirs civils et militaires s’accompagne de la construction de discours propagandistes visant à construire la figure d’un ennemi barbare et à entretenir la mobilisation tant des soldats que des arrières. En s’appuyant sur la réflexion précoce de Marc Bloch et les travaux d’historiens contemporains cet article de synthèse souligne les processus étroitement liés de la diffusion de fausses nouvelles et des rumeurs.
La crise des urgences
Authors: Pateron Dominique
Published: September 2023

La crise des urgences hospitalières peut être analysée comme le reflet amplifié de la crise des établissements hospitaliers mais elle ne se résume pas aux difficultés de ces établissements. Il existe des éléments spécifiques de la crise des structures d’urgence ou plus généralement de la médecine d’urgence : crise d’identité de la plus jeune des spécialités médicales, difficultés liées à l’augmentation d’activité et surtout aux difficultés d’hospitalisation des malades pris en charge par les services d’urgence, enfin qualité de vie des urgentistes.
Analysis and Bayesian estimation of a model for Chikungunya dynamics with relapse: An outbreak in Acapulco, Mexico
Authors: Vázquez-Peña María Guadalupe , Vargas-De-León Cruz , Camacho-Pérez Jorge Fernando , Velázquez-Castro Jorge
Published: September 2023

Chikungunya is a vector-borne viral disease transmitted by Aedes aegypti and Aedes albopictus mosquitoes. It does not have any specific treatment, and there is no vaccine. Recent epidemiological data have indicated that a relapse of the infection can occur within three months of the initial infection; however, until now, mathematical models for the spread of the disease have not considered this factor. We propose a mathematical model for the transmission of the Chikungunya virus that considers relapse. We calculated the basic reproductive number $ (R_0) $ of the disease by using the next-generation operator method. We proved the existence of a forward bifurcation. We determined the existence and the global stability of the equilibrium points by using the Lyapunov function method. We fitted the model to data from an outbreak in 2015 in Acapulco, Mexico to estimate the model parameters and $ R_0 $ with the Bayesian approach via a Hamiltonian Monte Carlo method. In the local sensitivity analysis, we found that the fraction of infected individuals who become asymptomatic has a strong impact on the basic reproductive number and makes some control measures insufficient. The impact of the fraction of infected individuals who become asymptomatic should be considered in Chikungunya control strategies.
Sharp criterion of global existence and orbital stability of standing waves for the nonlinear Schrödinger equation with partial confinement
Authors: Gong Min , Jian Hui , Cai Meixia
Published: September 2023

In this article, we consider the global existence and stability issues of the nonlinear Schrödinger equation with partial confinement. First, by establishing some new cross-invariant manifolds and variational problems, a new sharp criterion of global existence is derived in the $ L^{2} $-critical and $ L^{2} $-supercritical cases. Then, the existence of orbitally stable standing waves is obtained in the $ L^{2} $-subcritical and $ L^{2} $-critical cases by taking advantage of the profile decomposition technique. Our work extends and complements some earlier results.

Authors: Popovici Violina , Sturza Rodica , Ghendov-Mosanu Aliona
Published: September 2023

This chapter is related to the general characteristics of vegetable oils; the oxidative stability and the mechanism of lipid oxidation; the factors affecting the mechanism of lipid oxidation; the impact of lipid oxidation on the sensory properties of complex food products; and characteristics of the antioxidant complex from local horticultural products. Oil oxidation also destroys essential fatty acids and produces toxic compounds and oxidized polymers. It also affects the taste, nutritional quality, and toxicity of edible oils. Different chemical mechanisms, autoxidation, and photooxidation, are responsible for the oxidation of edible oils during processing and storage, depending on oxygen types. Two oxygen types can react with edible oils: atmospheric triplet oxygen, 3O2, and singlet oxygen, 1O2.
A Lévy Flight-Inspired Random Walk Algorithm for Continuous Fitness Landscape Analysis
Authors: Wang Yi , Li Kangshun
Published: September 2023

Heuristic algorithms are effective methods for solving complex optimization problems. The optimal algorithm selection for a specific optimization problem is a challenging task. Fitness landscape analysis (FLA) is used to understand the optimization problem's characteristics and help select the optimal algorithm. A random walk algorithm is an essential technique for FLA in continuous search space. However, most currently proposed random walk algorithms suffer from unbalanced sampling points. This article proposes a Lévy flight-based random walk (LRW) algorithm to address this problem. The Lévy flight is used to generate the proposed random walk algorithm's variable step size and direction. Some tests show that the proposed LRW algorithm performs better in the uniformity of sampling points. Besides, the authors analyze the fitness landscape of the CEC2017 benchmark functions using the proposed LRW algorithm. The experimental results indicate that the proposed LRW algorithm can better obtain the structural features of the landscape and has better stability than several other RW algorithms.
Unleashing Continuous Improvement and Competitive Advantage Through BP-Driven Knowledge Management Processes
Authors: Wang Jun , Wang Yanan , Liu Ou , Chong Woon Kian
Published: September 2023

The knowledge management process (KMP) requires continuous enhancement and is closely intertwined with the corresponding organizational business processes (BPs). Despite efforts to improve the integration of KMP and BPs, many knowledge management practices are ineffective due to the organizations' failure to incorporate their KMP with BPs. The lack of a structured approach to automate KMP improvement, driven by BP changes, is a major challenge. This study presents a BP-driven KMP modeling methodology, which has been employed in an aviation manufacturing enterprise's design institute to assist its KMP. The evaluation findings reveal that the approach can effectively facilitate the integration of BPs and KMP, as well as achieve BP-driven automation, ensuring the KMP's dynamic and continuous improvement. By incorporating this approach, organizations can automate their KMP improvement and respond to changes in their BPs more effectively, thereby improving their overall performance and competitiveness.
Dynamics and Effects of Science Technology Translation
Authors: Shi Jing , Wang Jiajie , Sun Jianjun
Published: September 2023

Considering the academic and industrial needs, it is necessary to examine the dynamics and effects of science and technology translation, especially the indirect ones. This study proposes a framework for identifying the levels of translation, called translational generation, and measuring their translational effects. An empirical analysis is carried out in the field of blockchain. The results provide evidence supporting the strength of direct translation and the growth of indirect translation. Firstly, the amount of S&T translation has increased and the amount of indirect translation has grown up to almost three times that of direct ones. Secondly, direct translation has better effects than all levels of indirect groups. However, the advantage of direct translation is not stable. It decreases in the translation intensity dimension and increases in the translation speed dimension. These findings have important implications for S&T innovation and source-allocated policy making.

Published: September 2023

In Maranhão State, Brazil, soils are naturally acidic, nutrient-deficient, and prone to cohesion and erosion. Removing the natural cover to establish pastures causes physical, chemical, and biological changes in the soil. Therefore, this study aimed to evaluate the contents and stocks of carbon (C), nitrogen (N), and particle-size fractions of soil organic matter (SOM) in pastures with different years of recovery, and compare them with a secondary forest in the Legal Amazon. Four treatments were evaluated: secondary forest, perennial pasture, and perennial pastures recovered for five years and eight years, both of the latter through corn + brachiaria intercropping. The contents and stocks of total organic carbon, total nitrogen, C, and N from the soil organic matter particle-size fractions, as well as the carbon management indexes (CMI) of the 0.00–0.10, 0.10–0.20, 0.20–0.30, and 0.30–0.40 m layers were evaluated. The perennial pasture environment presented the highest total soil C and N contents; however, when observing the granulometric fractions and CMI, these increases were qualitative in relation to the secondary forest. Pasture recovery over eight years contributed to an improvement of soil quality similar to secondary forest, indicating that an increase in SOM quality, quantity, and recovery time related to increased pasture capacity to accumulate C and N in the soil.

Published: September 2023

For decades, researches were developed about the diversity of fishes in the Amazon basin and their consumption by the people. In this context, an important gap identified was a lack of information about the nutritional composition of some of the main Amazon fish species consumed and traded. Front this, the objective of this study was to evaluate the chemical composition and mineral content of filets from 10 fish species with the highest landing volume in Amazonas State. The fish species selected were curimatã, jaraqui, mapará, matrinxã, pacu, piramutaba, sardinha, surubim, tambaqui and tucunaré. Were collected 20 samples (fishes) from each species according to the hydrological cycles of the region (20 samples in the flood and 20 samples in drought). Ten fish samples were processed to determine the proximal composition and 10 fish samples were used to determine mineral content (macro and micro minerals). The proximal composition of fish species analysed varied widely between species and seasons, with an emphasis on moisture and lipid content. Fishes in the flood season presented higher content of nutrients than drought season. This result also was observed in the minerals profile, where fishes in the flood season presented the highest (p < 0.05) minerals content.

Published: September 2023

Introduction: Asian populations are at an increased risk of cardiometabolic disorders due to higher fat mass at a relatively lower body mass index (BMI). Several discrepancies have been reported in the BMI classification systems currently in practice to assess the nutritional status among children. Aim of this study was to compare the different international BMI based classification systems to identify the nutritional status in a cohort of Sri Lankan children.Methods: A cross sectional study was conducted on 833 (48.37% boys) school children aged 5-15 years in Galle Municipality area, Sri Lanka. The nutritional status of each child was defined according to five BMI classification systems: World Health Organization (WHO), Centers for Disease Control and Prevention(CDC), and International Obesity Task Force (IOTF), Indian and Sri Lankan systems. The agreement between them was tested using Cohen’s kappa coefficient.Results: Prevalence of under-weight, overweight and obesity of children, as determined by the WHO, CDC, IOTF, Indian and the Sri Lankan classification systems showed significant differences. The WHO classification system had the best agreement (k=0.649) with the Indian classification system. A wide difference between the Sri Lankan classification system (24.37%) and the Indian (9.60%) and WHO (5.04%) classification systems in defining obesity were observed.Conclusion & recommendations: A wide difference between different BMI classification systems when determining the nutritional status in children emphasise the importance of developing a country-specific classification system to identify the nutritional status among Sri Lankan children.
Athletic Trainers’ Observations of Social Determinants of Health in the Collegiate Setting: A Card Study
Authors: Picha Kelsey J. , Welch Bacon Cailee E. , Evans Windsor Cassidy , Lewis Joy H. , Snyder Valier Alison R.
Published: September 2023

Context

Addressing social determinants of health (SDOH) in all populations improves patient outcomes, leading to better patient-centered care. Despite known influences of SDOH, little is known about the ability of athletic trainers (ATs) to observe SDOH in practice.

Objective

To explore ATs’ observations of SDOH and describe actions taken at the point of care in collegiate and university settings.

Design

Descriptive via an observational card study.

Setting

Athletic training facilities.

Patients or Other Participants

Collegiate and university ATs (23 participants across 20 institutions).

Data Collection and Analysis

The ATs used a modified observation card to document observations of SDOH during patient encounters in the collegiate or university setting. The cards contained instructions for completion and a table with 4 columns: (1) a list of 19 predetermined SDOH, (2) a checkbox for observed SDOH, (3) a checkbox for the perceived negative influence of observed SDOH on patient health, and (4) an open box to write in what actions, if any, were taken to address the observed SDOH.

Results

Overall, 424 cards were collected. Of 725 observed SDOH, access to social media (153/725, 21.1%), academic stressors (131/725, 18.1%), and behavioral health issues (71/725, 9.8%) were the most commonly observed. Nearly 39% (281/725) had a perceived negative influence. Of those, academic stressors (49/281, 17.4%), behavioral health issues (46/281, 16.4%), and transportation issues (32/281, 11.4%) were most common. For the 23.0% (166/725) of SDOH acted upon, ATs used counseling and education (73/166), provided additional resources (60/166), referred to others (29/166), or communicated with others (4/166).

Conclusions

Because ATs are positioned to accurately assess SDOH, they can promote better patient-centered care and improve patient outcomes. Our results suggest that many SDOH observed by ATs in the collegiate or university setting have a negative influence on patient health. Better support for patients with academic stressors and behavioral health issues is important because of these SDOH.

Published: September 2023

Purpose:

To report a big data analysis of risk and protective factors in patients with AMD, as well as report on the age-adjusted prevalence in a geriatric Indian cohort in a hospital setting.

Methods:

This retrospective, observational study of all patients older than 60 years of age. Multiple logistic regression was performed for the binary outcome and the presence of AMD. Variables analyzed include age, gender, socioeconomic status, occupation, urban–rural–metropolitan distribution, self-reported history of diabetes mellitus (DM), hypertension (HTN), or coronary artery disease (CAD), ocular comorbidities, history of cataract surgery, and presenting VA. Odds ratios (OR) and 99% confidence intervals were calculated.

Results:

Of the 608,171 patients over the age of 60 years who attended our clinics, 1.68% of subjects had a diagnosis of AMD (N = 10,217). Less than half (4,621 of 10,217 with AMD) of them were diagnosed to have dry AMD. Cataract, glaucoma, and diabetic retinopathy were associated with lower risk of AMD. Cataract surgery was associated with the higher risk of AMD (OR = 1.20; 99% CI 1.13-1.29). Smoking was not associated with AMD.

Conclusion:

Big data analysis from a hospital setting shows that the prevalence of AMD above the age of 60 years is low. More patients with wet AMD present for treatment compared to dry AMD. Smoking was not associated with AMD in the Indian population. Cataract surgery was associated with higher prevalence of AMD.

Published: September 2023

Purpose:

To evaluate visual acuity (VA) outcomes and complications from resident physician-performed cataract surgery in a diverse Veterans Affairs Hospital population.

Methods:

A retrospective chart review was conducted for patients who underwent cataract surgery performed by resident physicians from 01/01/2013 to 12/31/2015 at the Veterans Affairs Medical Center. Intraoperative and postoperative clinical information, best-corrected VA (BCVA) (1 day, months 1, 2-3, and 6), and surgery complications were extracted. Univariable and multivariable linear regression models were performed for risk factors of BCVA change.

Results:

This study included 1183 patients, with mean (SD) age of 70.8 (9.3) years. 1154 (97.5%) were males, 493 (41.7%) African-American, and 681 (57.6%) Caucasian. The mean (SD) VA in logMAR was 0.69 (0.74) at baseline, improved to 0.19 (0.36) at 1 month, 0.16 (0.34) at 2-3 months, and 0.14 (0.36) at 6 months. 1080 (91.3%) patients experienced VA improvement from baseline and 1023 (86.5%) patients achieved at least 20/40 BCVA at 1 month. There were 86 (7.3%) complications, most commonly including 47 (4.0%) posterior capsular tears and 64 (5.4%) vitreous loss. In multivariable analysis, younger age (P < 0.0001), worse baseline VA (P < 0.0001), and absence of iris prolapse (P < 0.001) were significantly associated with greater improvement in VA at 1 month.

Conclusion:

In a diverse VAMC, resident-performed cataract surgeries achieved significant improvement in VA with a cumulative complication rate lower than previously reported. Resident physician education may benefit from specific focus on prevention of iris prolapse and better incision construction during surgery as these intraoperative events often led to delayed stabilization of visual outcome beyond 1 month.
Temporal artery biopsy for suspected giant cell arteritis: A mini review
Authors: Jiang Zhijian , Ji Huiying , Dong Jianhong
Published: September 2023

Giant cell arteritis (GCA) is a granulomatous inflammation involving medium and large vessels that can lead to serious clinical manifestations associated with tissue ischemia. Temporal artery biopsy (TAB) is currently the gold standard method for the diagnosis of GCA, with a specificity of 100% and a sensitivity of 77%. However, the false-negative rate for TAB ranges from 9% to 61%. False negatives may be related to the timing of biopsy, the length of specimen, and the existence of “skip lesions.” We reviewed the relevant evidence for methods to improve the sensitivity and reduce the false-negative rate for TAB. To reduce the false-negative rate for TAB, it is recommended to perform TAB within 1 week of starting corticosteroid therapy. Although there is currently no consensus, we suggest that the temporal artery is cut to a length of 20‒30 mm and to prepare serial pathological sections. It is necessary to attach great importance to patients suspected of having GCA, and complete TAB should be performed as soon as possible while starting corticosteroid therapy promptly. We also discuss the clinical value of non-invasive vascular imaging technologies, such as DUS, CTA, MRA, and 18F-FDG-PET/CT, as auxiliary methods for GCA diagnosis that could partially replace TAB.
Quantitative evaluation of retinal and choroidal microcirculation in inactive ocular sarcoidosis
Authors: Yalcinsoy Kubra Ozdemir , Erol Yasemin Ozdamar , Hondur Gozde , Ozdal Pinar Cakar
Published: September 2023

Purpose:

To evaluate retinal and choroidal alterations in eyes with inactive ocular sarcoidosis and to compare the findings with healthy controls.

Methods:

This cross-sectional study included 11 patients with inactive ocular sarcoidosis (study group) and 11 healthy individuals (control group). Retinal and choroidal vascular differences were evaluated using optical coherence tomography angiography (OCTA) and enhanced depth imaging–optical coherence tomography (EDI-OCT).

Results:

A total of 21 eyes of ocular sarcoidosis patients without active inflammation and 22 eyes of healthy controls were analyzed. The mean whole-image deep capillary plexus vessel density was significantly lower in the study group than in the control group (P = 0.03). The acircularity index values were significantly higher, and the foveal density-300 values were significantly lower in the study group than in the control group (P = 0.01, both). The flow areas of the choriocapillaris at 1-, 2-, and 3-mm radius areas were also significantly lower in the study group (all P < 0.01). The mean choroidal thickness (CT) was significantly lower in all regions between nasal and temporal at 3000 μm in the study group (all P < 0.05). The choroidal vascularity index (CVI) values were also significantly lower in the study group (P < 0.01).

Conclusion:

Ocular sarcoidosis was associated with a reduction in CT and the CVI with a decrease in retinal vessel density and choriocapillary flow parameters. The combination of OCTA and EDI-OCT imaging may be useful in monitoring ocular sarcoidosis eyes to detect alterations in the retinal and choroidal layers.
Cerebral visual impairment and effect of phase-wise stimulation strategies—An interim analysis
Authors: Smitha KS , Kurbet Bhagyajyothi , Kamate Mahesh , Veenish Samvedya
Published: September 2023

Context:

Cerebral visual impairment (CVI) is an overarching term, defined as a brain-based visual impairment with onset in childhood, unexplained by an ocular disorder and associated with unique visual and behavioral characteristics. Good vision and awareness of visual function in a child are highly essential as neuroplasticity is maximum in the first three years of life and response to intervention is utmost in this period. Awareness is lacking regarding CVI, and the diagnosis is largely missed. This can be easily addressed if a structured approach is employed.

Purpose:

This study aims to evaluate the etiology and radiological correlation with the severity of CVI and outcome after structured intervention in children with CVI.

Settings and Design:

Prospective—interventional study.

Methods and Material:

Children attending the Child Development Centre (CDC) of a tertiary care hospital in North Karnataka and diagnosed with CVI in the age group of six months to 12 years and meeting the sampling criteria were screened and enrolled consecutively after obtaining parental consent/assent. Statistical analysis used is nonparametric test with SPSS software.

Results:

Age showed a significant association with the phase of CVI. Perinatal insult was associated significantly with the severity of CVI. Magnetic resonance imaging (MRI) findings did not hamper the recovery of CVI.

Conclusions:

Enrolment in early intervention programs tailored according to child’s specific needs should be encouraged, with stress on ophthalmic screening of preterm and high-risk babies with perinatal hypoxia and history of convulsions, as early as six months.
High false-positive response in perimetry
Authors: Mansoori Tarannum
Published: September 2023

Background:

In Humphrey visual field analyzer, the false-positive (FP) responses imply that the patient has pressed the response button despite no stimulus being seen at the time of response and FP rates >15% are flagged. The classical “Trigger happy” visual field has increased fixation loss, very high threshold retinal sensitivity with the values in supernormal range, “white scotoma” on grayscale map, high positive mean deviation (MD), glaucoma hemifield test (GHT) gives classification of “abnormally high sensitivity, ‘Excessive high false positive’ message is displayed,” and pattern deviation probability plot has more defects than total deviation probability plot known as “reverse cataract pattern.” However, these classical findings are not seen in all the cases of FP as the same thumb rule cannot be applied to all the visual fields with high FP.

Purpose:

This video emphasizes the significance of careful examination of all the parameters in a visual field printout of high FP to interpret the test results and the caution needed when an FP response is seen in a patient with advanced glaucoma.

Synopsis:

The video presents some interesting visual fields in normal and glaucoma patients and the effect of high FP responses on MD, the different classification messages displayed for GHT, patterns of total deviation probability plot and pattern deviation probability plot, and how to identify the hidden FP.

Highlights:

This video highlights the importance of careful examination of all the parameters in a visual field printout to interpret the test results. One should be especially cautious when an FP response is noted in a patient with advanced glaucoma, as the retinal sensitivity values may not be in supernormal range but are significantly affected by the increased FP. Clinician should be able to identify this and repeat the test as high FP reponses can lead to underestimation of visual field loss.

Published: September 2023

Indocyanine green (ICG) is a water-soluble fluorescent dye that is minimally toxic and widely used in gastrointestinal surgery. ICG facilitates anatomical identification of structures (e.g., ureters), assessment of lymph nodes, biliary mapping, organ perfusion and anastomosis assessment, and aids in determining the adequacy of oncological margins. In addition, ICG can be conjugated to artificially created antibodies for tumour markers, such as carcinoembryonic antigen for colorectal, breast, lung, and gastric cancer, prostate-specific antigen for prostate cancer, and cancer antigen 125 for ovarian cancer. Although ICG has shown promising results, the optimization of patient factors, dye factors, equipment, and the method of assessing fluorescence intensity could further enhance its utility. This review summarizes the clinical application of ICG in gastrointestinal surgery and discusses the emergence of novel dyes such as ZW-800 and VM678 that have demonstrated appropriate pharmacokinetic properties and improved target-to-background ratios in animal studies. With the emergence of robotic technology and the increasing reporting of ICG utility, a comprehensive review of clinical application of ICG in gastrointestinal surgery is timely and this review serves that aim.

In addition, ICG can be conjugated to artificially created antibodies for tumour markers, such as carcinoembryonic antigen for colorectal, breast, lung, and gastric cancer, prostate-specific antigen for prostate cancer, and cancer antigen 125 for ovarian cancer. Although ICG has shown promising results, the optimization of patient factors, dye factors, equipment, and the method of assessing fluorescence intensity could further enhance its utility. This review summarizes the clinical application of ICG in gastrointestinal surgery and discusses the emergence of novel dyes such as ZW-800 and VM678 that have demonstrated appropriate pharmacokinetic properties and improved target-to-background ratios in animal studies. With the emergence of robotic technology and the increasing reporting of ICG utility, a comprehensive review of clinical application of ICG in gastrointestinal surgery is timely and this review serves that aim.
