Authors: Barbosa Maria , Katz A.
Published: February 2023

Trichomycterus giarettai, new species, from a small river in Cumari municipality, Central Brazil is described. It is hypothesized to be closely related to species of T. brasiliensis complex by possessing the opercular odontodes disposed obliquely on the patch. Trichomycterus giarettai is diagnosed by the distribution of infraorbital pores, body width, caudal peduncle width, number of vertebrae, branchiostegal rays, dorsal and ventral procurrent rays, opercular and interopercular odontodes, length of the nasal barbels, and pelvic fin insertion.
A redescription, a revalidation, and a new description within the microhylid genus Austrochaperina (Anura: Microhylidae)
Authors: Günther Rainer
Published: February 2023

The genus Austrochaperina Fry, 1912, currently includes 23 species of small and medium-sized frogs which occur primarily in New Guinea and its surrounding islands. Through studies of the frog fauna carried out in various years between 1998 and 2003 in the Wondiwoi Mountains at the base of the Wandammen Peninsula, located on the border between the Indonesian provinces of Papua and Papua Barat, the author noted three forms in the genus Austrochaperina. One of these has already been described as a new species, A. minutissima, by Günther (2009). The second is most likely A. macrorhyncha (Kampen, 1906), which was described from a single available specimen from the Vogelkop Peninsula. Data provided herein by the author makes it clear that the current definition of this species is not accurate and that a redescription of it is necessary. In connection with this is the revalidation of another species, A. punctata (Kampen, 1913), considered to be a synonym of A. macrorhyncha. The third form is considered to be new to science, and it is described as such in this paper. This species occurs at an elevation of from 400 – 650 m above sea level in and on leaf litter primarily near streams in primary rainforest. The adult is 25 – 30 mm long. It is differentiated from related species in several body proportions and by its characteristic advertisement calls, and from the sympatric but obviously not syntopic A. macrorhyncha in the base sequences of the mitochondrial 12S rDNA- and 16S rDNA-genes as well.
Négocier la précarité ? Solidarité et prédation dans les négociations ordinaires des managers au sujet des travailleurs extérieurs
Authors: Jacob Marie-Rachel
Published: February 2023

Les négociations ordinaires ont été pensées comme un processus de construction d’un ordre social ordinaire, négocié par les acteurs en interaction pour obtenir la satisfaction de leurs souhaits respectifs. Cet article cherche à comprendre comment l’éclatement du cadre salarial traditionnel au travers du recours à des relations d’emploi triangulaires reconfigure l’ordre social dans l’entreprise cliente. Une enquête réalisée par observation participante dans une direction d’un grand groupe permet d’analyser les négociations ordinaires des managers au sujet des travailleurs extérieurs. Ces négociations se révèlent porteuses d’une ambivalence entre solidarité et prédation plutôt qu’entre coopération et affrontement, comme établi dans la littérature. L’ambiguïté sur les résultats produits se mesure en termes de précarité pour les travailleurs extérieurs concernés. Quatre résultats sont précisés en matière de négociations ordinaires conduites par les managers de l’entreprise cliente (avec la direction des ressources humaines et entre managers), de leurs effets combinés avec le statut d’emploi, ainsi que des causes de rupture anticipée de la relation de travail et leurs effets sur la satisfaction au travail et la stabilité de l’emploi des travailleurs extérieurs.

Bus timetable optimization model in response to the diverse and uncertain requirements of passengers for travel comfort
Authors: Lin Peiqun , He Chenxing , Zhong Lingshu , Pei Mingyang , Zhou Chuhao , Liu Yang
Published: February 2023

Most existing public transit systems have a fixed dispatching and service mode, which cannot effectively allocate resources from the perspective of the interests of all participants, resulting in resource waste and dissatisfaction. Low passenger satisfaction leads to a considerable loss of bus passengers and further reduces the income of bus operators. This study develops an optimization model for bus schedules that considers vehicle types and offers two service levels based on heterogeneous passenger demands. In this process, passenger satisfaction, bus company income, and government subsidies are considered. A bilevel model is proposed with a lower-level passenger ride simulation model and an upper-level multiobjective optimization model to maximize the interests of bus companies, passengers, and the government. To verify the effectiveness of the proposed methodology, a real-world case from Guangzhou is presented and analyzed using the nondominated sorting genetic algorithm-Ⅱ (NSGA-Ⅱ), and the related Pareto front is obtained. The results show that the proposed bus operation system can effectively increase the benefits for bus companies, passengers, and the government.
A double-channel multiscale depthwise separable convolutional neural network for abnormal gait recognition
Authors: Liu Xiaoguang , Wu Yubo , Chen Meng , Liang Tie , Han Fei , Liu Xiuling
Published: February 2023

Abnormal gait recognition is important for detecting body part weakness and diagnosing diseases. The abnormal gait hides a considerable amount of information. In order to extract the fine, spatial feature information in the abnormal gait and reduce the computational cost arising from excessive network parameters, this paper proposes a double-channel multiscale depthwise separable convolutional neural network (DCMSDSCNN) for abnormal gait recognition. The method designs a multiscale depthwise feature extraction block (MDB), uses depthwise separable convolution (DSC) instead of standard convolution in the module and introduces the Bottleneck (BK) structure to optimize the MDB. The module achieves the extraction of effective features of abnormal gaits at different scales, and reduces the computational cost of the network. Experimental results show that the gait recognition accuracy is up to 99.60%, while the memory size of the model is reduced 4.21 times than before optimization.
En lieu et place de l’« invention du marché »…
Authors: Postel-Vinay Gilles
Published: February 2023

Pour des archéologues qui s’interrogent sur ce que seraient pour eux les conditions d’usage de la notion de marché, une intervention sur les marchés du crédit dans la France du XVIIIe au début du XXe siècle pourra sembler bien exotique. Peut-être se justifie-t-elle néanmoins dans la mesure où elle invite à déplacer les analyses. Dans la période considérée, souvent pensée comme marquée par la mise en place plus ou moins rapide d’un marché du crédit, ce sont différents marchés qui émergent et coexistent, chacun suivant sa logique et sa chronologie propre. Ainsi, dans la France d’alors, se sont tôt développés à l’écart des banques des réseaux d’intermédiaires – en l’occurrence les notaires – aptes à certifier la fiabilité des garanties (immobilières) offertes et, partant, à mettre en rapport emprunteurs et prêteurs. Longtemps resté inaperçu, un tel système a fonctionné à si grande échelle qu’un tiers des familles y a recours vers 1740 et que, vers 1840, il mobilise à moyen et long terme des sommes qui, rapportées à l’économie d’alors, sont comparables aux prêts hypothécaires réalisés par les banques américaines du milieu du XXe siècle.
Les archéozoologues face à l’économie : esquisse d’une question
Authors: Bridault Anne , Frère Stéphane
Published: February 2023

L’archéozoologie se constitue à l’échelle internationale à la fin des années 1970-début des années 1980. Les aspects concernant les techniques d’analyse et les protocoles de récolte des vestiges animaux sur le terrain sont mis en avant. Il y a en effet nécessité d’établir un minimum méthodologique commun pour l’acquisition et le traitement de données quantitatives comparables. Comment les archéozoologues se sont-ils emparés des questions d’économie dans les sociétés anciennes ? Deux configurations semblent se dessiner : les travaux en économie préhistorique ont été influencés pour partie par ceux de l’anthropologie économique, tandis que, pour les périodes historiques, les travaux abordent les questions de production et de commerce d’animaux et de viandes, dans le sillon de l’histoire économique dont ils ne se revendiquent pourtant guère, cherchant plutôt une voie indépendante. Après un aperçu historiographique, cet article propose un focus sur la France et examine le développement des contributions des archéozoologues à la caractérisation de comportements et de systèmes économiques, de l’Antiquité à la fin du Moyen Âge pour la moitié nord de la France.

Published: February 2023

Tempeh gembus is a traditional Indonesian prepared from solid tofu waste fermented by Rhizopus oligosporus. It contained some nutritional value and bioactives from fermentation, making tempeh gembus a functional food with variety of health benefits. Previous research had investigated functional properties of tempeh gembus, such as amidolytic, antimicrobial, and antioxidant, as well as proteolytic, fibrinolytic, fibrinogenolytic, and anti-inflammation, which were linked to a variety health benefits, including atherosclerosis, diabetes mellitus, hyperlipidaemia, obesity, metabolic syndrome, and osteopenia. Tempeh gembus is sometimes underestimated because it is prepared from tofu waste and is frequently consumed by low-income people due to its low cost. Tempeh gembus intake is also low due to a lack of knowledge about its health benefits. This article reviews the health benefits of tempeh gembus as one of Indonesia's local functional foods.
Establishing DST and Push-Pull Theory for Internationalization Best Practices in Higher Education
Authors: Najimdeen Hakeem Alade , Amzat Ismail Hussein
Published: February 2023

The rapid socioeconomic growth of emerging countries, as well as the changing character of higher education services because of the Coronavirus epidemic, warrant rethinking the internationalization approach in higher education. In the age of inconsistency in internationalization policies, this chapter argues that dynamic systems theory (DST) can be adopted for implementing internationalization. It also explores push-pull dynamics, which can be utilized as an alternative to the classic push-pull theory to enhance the competitive advantage in this era of limited funds for higher institutions, and low turnout from international student mobility. The chapter concludes on the approach and recommendations that can assist in determining what to focus on and the future trends in higher education internationalization.

The chapter also includes a discussion of the strategies of some U.S. universities to offset the adverse effects of COVID-19 on their internationalization efforts.
Internationalization of Higher Education
Authors: Rahal Aicha
Published: February 2023

Internationalisation has become essential in higher education to prepare institutions for participation in the global environment. English as a medium of instruction (EMI) is considered as an internationalizing policy at universities. It is defined by Dearden (2014) as the “use of the English language to teach academic subjects in countries or jurisdictions where the first language (L1) of the majority of the population is not English” (p. 2). This chapter mainly aims at exploring Tunisian teachers' and students' attitudes towards the use of English as a language of instruction in tertiary education. The chapter starts by giving an overview of the language situation in Tunisia, placing an emphasis on English language in education policy. After that, the chapter discusses some important empirical findings based on the data collected from a questionnaire among 50 university teachers and students. The study may contribute to extend the research on EMI in higher education and its effect on students' performance in Tunisia.
The Societal and Educational Transformation Projects
Authors: Trad Antoine Toni
Published: February 2023

The Phoenicians' affinity for education, innovative temperament, culture, and discipline enabled them to develop complex domains, like education. These fields were developed by this exceptional nation, which used Aramaic as their lingua franca; but they have also faced many grave challenges, genocides, and even risks of extinctions. As the combination of targeted subject(s) is/are complex and sensitive, this chapter focuses on the Semite-Phoenicians (SP) or today's Lebanese, their heritage, and the evolution of their specific diverse educational and multi-cultural system(s). SP's heritage, education, knowledge, and culture has spread throughout the world. SPs inhabited the MC that extended from Tyrus to the Nordic city of Tripoli. For more than six thousand years, Lebanon designates a region that has never changed its name. SP city states were avant-garde posts for their cultural expansion and these well-organized expansions brought them societal, economic successes. This chapter presents the ELDES in the context of the Lebanese societal transformation.
Corporate Social Reasonability Roles in Artificial Intelligence and Big Data Analytics in Management
Authors: Rupp Willian R. , Smith Alan D.
Published: February 2023

Cooperate social responsibility (CSR) has presented a new set of challenges in the emerging era of artificial intelligence (AI) and big-data analytics to managerial decision-makers and investors alike. Access and statistical manipulation of personally sensitive information as well as transaction datasets provide an opportunity for CSR and the social contract, which examines the relationship of workers with a living wage versus automation, between society and corporate leaders. The initial cost of developing and deploying the appropriate hardware and the software for automation, especially if does not pass the costs-benefit test, may not labor replacement based on operational elements alone (e.g., high levels of output, improved quality, reduced fewer errors, reduced administration and monitoring) may be more important that just reducing labor costs. A discussion of the characteristics of automation in light of AI and big-data analytics in managerial decision making and its relationship to the tenants of CSR that takes care of people before profits highlights these opposing forces.

Authors: Xu Wei , Zhai Yujin
Published: February 2023

Due to its simplicity, directness, and rich content, home video surveillance has gradually become the core content of the smart home security system. The rapid development of computer technology, the internet, video image processing, and transmission technology, as well as the emergence of “wireless cities,” have continuously expanded the coverage of wireless internet such as 5G and WiFi and greatly changed data processing methods and transmission speeds. Video surveillance has also gradually developed from traditional wired networking to mobile video surveillance of wireless networks. Therefore, this paper will focus on the design of the home video monitoring system based on the IoT location service. The system combines traditional network video surveillance with intelligent mobile terminals, which can meet the needs of users for video surveillance of home conditions at any location and at any time. And it compared the sensitivity, accuracy, capture time interval, and energy consumption of the two by comparing with traditional internet video surveillance.

Authors: Savalia Meshwa Rameshbhai , Verma Jaiprakash Vinodkumar
Published: February 2023

Breast cancer is the second major cause of cancer deaths in women. Machine learning classification techniques can be used to increase the precision of diagnosis and bring it closer to 100%, thus saving the lives of many people. This paper proposed four different models, built using different combinations of selected features and applying five ML classification techniques to all the models to identify the best model with the highest accuracy. It analyzes five machine learning techniques, namely logistic regression (LR), support vector machines (SVM), naive bayes (NB), decision trees (DT), and k-nearest neighbor (KNN), for prediction of breast cancer using the Wisconsin Diagnostic Breast Cancer Dataset on these four models. The objective of the paper is to find the best ML algorithm that can most accurately predict breast cancer for a particular model. The outcome of this paper helps the doctors to improvise the diagnosis by knowing the effect of combinations of symptoms with the growth of breast cancer.
Designing Learning Environments That Support Diverse Students' Needs in a Teacher Education Program
Authors: Sande Beverly , Burnett Camille S.
Published: February 2023

The need to design learning environments (virtual, hybrid, and face-to-face) that support racial and ethnic minority students' academic success has increased tremendously. The data presented here were collected via a cross-sectional survey of 59 students at Historically Black Colleges and Universities (HBCU) as part of a more extensive study that included closed- and open-ended questions. The data were collected mid-fall 2020 semester, and data were gathered until the end of spring 2021. During this period, all activities were conducted remotely because of the pandemic. Face-to-face instruction was non-existent compared to “normal situations.” Summary statistics of the closed-ended questions highlighted the challenges students encountered in their learning environments and were further confirmed through the recurring themes identified in responses to the open-ended questions. Findings were used to recommend designing learning environments undergirded by culturally responsive teaching and a humanizing pedagogy.

Computation Offloading Method for Large-Scale Factory Access in Edge-Edge Collaboration Mode
Authors: Man Junfeng , Zhao Longqian , Xu Bowen , Peng Cheng , Jiang Junjie , Liu Yi
Published: February 2023

Large-scale manufacturing enterprises have complex business processes in their production workshops, and the edge-edge collaborative business model cannot adapt to the traditional computation offloading methods, which leads to the problem of load imbalance. For this problem, a computation offloading algorithm based on edge-edge collaboration mode for large-scale factory access is proposed, called the edge and edge collaborative computation offloading (EECCO) algorithm. First, the method partitions the directed acyclic graphs (DAGs) on edge server and terminal industrial equipment, then updates the tasks using a synchronization policy based on set theory to improve the accuracy effectively, and finally achieves load balancing through processor allocation. The experimental results show that the method shortens the processing time by improving computational resource utilization and employs a heterogeneous distributed system to achieve high computing performance when processing large-scale task sets.
Selecting Rotation Constants on SIMON-Type Ciphers
Authors: Zhang Kai , Lai Xuejia , Guan Jie , Hu Bin
Published: February 2023

In 2013, a lightweight block cipher SIMON is proposed by NSA. This paper tries to investigate this design criterion in terms of resisting against impossible differential cryptanalysis. On one hand, starting from all the possible rotation constants, this paper sieves those “bad parameters” step by step, for each step, the regular patterns for those “bad parameters” are deduced. Accordingly, basic rules for selecting rotation constants on SIMON-type ciphers to construct shorter longest impossible differentials are proposed. On the other hand, the authors categorize the optimal parameters proposed in CRYPTO 2015, according to these results, some “good parameters” in terms of differential cryptanalysis may be rather “bad parameters” while considering impossible differential cryptanalysis. Finally, a concrete attack on 26-round SIMON(13,0,10) is proposed, which is a suggested SIMON variant in CRYPTO 2015 against differential cryptanalysis and linear cryptanalysis. The result in this paper indicates that it is very important to choose appropriate rotation constants when designing a new block cipher.

Para esto, se ha realizado una búsqueda, revisión y sistematización de la literatura internacional (libros y artículos) y de revistas de estudios migratorios, de género y familia. Planteamos que en esta discusión convergen dos ejes analíticos. El primero de ellos proviene de los estudios sobre familias migrantes transnacionales y el segundo, de los estudios sobre cuidados. A través de la revisión de la literatura identificamos los principales aportes que cada uno de estos ejes entrega al análisis de los cuidados de las personas mayores en contextos migratorios transnacionales y revisamos a su vez algunas ausencias y puntos ciegos con el objetivo de puntualizar agendas emergentes de investigación en esta temática.
Diagnostic Evaluation of Mechanical Ankle Instability by Comparing Injured and Uninjured Contralateral Ankles Using Arthrometry
Authors: Chen Yungu , Cao Shengxuan , Wang Chen , Zhang Chao , Huang Jiazhang , Wang Xu , Ma Xin
Published: February 2023

Context

Individuals with mechanical ankle instability (MAI) have obvious lateral ligament laxity and excessive ankle joint motion beyond the physiological range. Arthrometry has been introduced to quantitatively measure the laxity of the ankle joint. However, the diagnostic accuracy of arthrometry in MAI is still debatable.

Objectives

To (1) evaluate the difference in laxity between bilateral ankles in patients with and those without MAI and (2) calculate the diagnostic accuracy of ankle arthrometry using bilateral comparisons.

Design

Cross-sectional study.

Setting

Research laboratory.

Patients or Other Participants

A total of 38 individuals with unilateral MAI (age = 31.24 ± 7.90 years, height = 168.93 ± 7.69 cm, mass = 65.72 ± 10.47 kg) and 38 individuals without MAI (control group; age = 32.10 ± 7.10 years, height = 166.59 ± 7.89 cm, mass = 62.93 ± 10.72 kg).

Main Outcome Measure(s)

Bilateral ankle laxity in each participant was quantitatively measured by performing the arthrometric anterior drawer test. Continuous data of loading force and joint displacement were recorded. Data from both ankles were compared for the ankle joint displacement at a loading force of 75 N (D75) and load-displacement ratio from 10 to 40 N (LDR 10–40).

Results

The D75 between injured and uninjured ankles in patients with MAI was different (t37 = 9.78, P < .001). The mean LDR 10–40 in injured ankles was higher than that in uninjured ankles (t37 = 9.80, P < .001). In the control group, no differences were found between the left and right ankles. The MAI group had larger bilateral differences than the control group (t37 range = 7.33–8.18; P < .001). When LDR 10–40 was used to diagnose MAI, the arthrometer showed sensitivity and specificity of 0.900 and 0.933, respectively, with a cutoff value of 0.0351 mm/N.

Conclusions

An ankle arthrometer can be used to quantitatively measure the difference in bilateral ankle laxity in patients with MAI. Arthrometer-measured LDR 10–40 can be used to diagnose MAI with high diagnostic accuracy.
Prevalence and Association of Exercise Dependence and Eating Disorder Risk in Collegiate Student-Athletes
Authors: Uriegas Nancy A. , Moore Kenya , Torres-McGehee Toni M.
Published: February 2023

Context

Exercise dependence (EXD) is a compulsive and addictive behavior that can negatively affect physical and mental health, leading to significant impairment or distress. Exercise dependence has been associated with symptoms of eating disorders (EDs). Student-athletes are an at-risk population for EXD and EDs given the physical and psychological demands of competitive sports.

Objective

To examine the EXD and ED risks in student-athletes across sex and sport category and to determine the association between EXD and ED.

Design

Cross-sectional study.

Setting

Collegiate athletics.

Patients or Other Participants

National Collegiate Athletic Association Division I and II student-athletes (n = 1885; age = 19.8 ± 1.4 years; females = 69.6%, n = 1312; males = 30.4%, n = 573).

Main Outcome Measure(s)

A web-based survey including demographics, the Exercise Dependence Scale-21, the Eating Attitudes Test-26, and questions about pathogenic behaviors.

Results

Overall, 4.9% (n = 92) of the student-athletes were categorized as at risk for EXD (females = 4.8%, n = 63/1312; males = 5.1%, n = 29/573), with differences across sex and sport categories (all: χ28,1885 = 99.1, P < .001). The ED risk in student-athletes (Eating Attitudes Test-2, pathogenic behavior use, or both) was 22.7% (n = 428; females = 25.5%, n = 334/1312; males = 16.4%, n = 94/573), with differences by sex (χ24,1885 = 10.1, P = .039). Multiple logistic regressions indicated a significant association between the risks of EXD and ED for all student-athletes; athletes at risk for EXD were also at greater risk for EDs (odds ratio = 5.104; 95% CI = 3.237, 8.046) than nondependent-asymptomatic athletes (odds ratio = 2.4068; 95% CI = 1.5618, 3.7089).

Conclusions

Although physical activity has become a public health intervention to improve overall health in populations, EXD can be considered a problem related to physical activity. Exercise dependence can negatively affect physical and mental health, whereas EDs may be psychiatric disorders influenced by EXD, as exercise can be a compensatory behavior to achieve weight loss. To minimize the overall risk of EDs in student-athletes, additional education and awareness are needed. Special attention should be given to any student-athletes, in particular females, who display signs of EXD.
Systematic, substantive and functional comparison between the holy Qur’an and Pancasila
Authors: Acim Subhan A. , Sumardi Lalu
Published: February 2023

The Qur’an and Pancasila are two sources of Indonesian values that are existentially different from each other. Despite the difference, they both factually could walk in harmony, and it is important to seek the similarities and differences between them. This article presents the systematic, substantive, and functional reasons for how they could work altogether by looking at the similarities and differences in anatomy, taxonomy, substance, and function of each component of the Qur’an and Pancasila. Utilizing a naturalistic approach with content analysis genre, the writers collected the data from various documents, including; manuscripts of the Qur’an, Pancasila, speeches of the founding fathers of Indonesia, and the previous research results using document recording sheets. The collected data were analyzed through content analysis techniques and displayed in pictures and tables. The results showed: (1) the anatomy of the Qur’an consists of four components, namely: divinity, law, history, and story, while the anatomy of Pancasila only consists of a law component; (2) the taxonomy of the Qur’an is intersected with one another, while the taxonomy of Pancasila is stratified. The values in all components are generally the same, and the divine value is the primary value. The taxonomy of values in Pancasila is degraded and systemic, with the divine value as the main value / encompassing other values (prima causa); (3) the Qur’an’s substance covers all life dimensions while the dimensions of Pancasila are limited to law. One of the essential points in this section is that Pancasila makes the Qur’an a source of value; (4) the Qur’an is partially or holistically functional while Pancasila is holistically functional. Therefore, componential and substantial, the Qur’an and Pancasila have similarities, while structurally and functionally, they are different.Contribution: The results of this study described a systematic sequence, substantive relationships and functional pattern between the Qur’an and Pancasila. These research findings are expected to reduce misunderstandings among the Indonesian people about the Qur’an and Pancasila.

Background:

Weight gain is an ongoing challenge when initiating insulin therapy in patients with Type 2 diabetes mellitus. The aim of this study is to observe and compare the effect of commonly used regimens of insulin on body mass index (BMI) among Type 2 diabetes patients.

Methods:

An observational study was conducted in two diabetic centers in Dhaka starting from July 2018 to June 2019. During the 12 weeks of the data collection period, a total of 100 patients were included according to selection criteria and then divided into two equal groups. Patients who were prescribed with premixed (conventional or analog) 30/70 insulin twice daily with or without oral Antidiabetic drugs were included in Group I (n = 50) and the patients who were prescribed with insulin glargine once daily with a bolus insulin (conventional or analog) three times before large meals with or without oral Antidiabetic drugs were included in Group II (n = 50). BMI was calculated from the height and weight of the patients initially as baseline data and again after 12 weeks of treatment in both groups. Fiber Bragg grating, 2 h ABF, and hemoglobin A1C (HbA1c) change were also observed among the patients of both insulin groups from diagnostic reports during the study period.

Results:

After 12 weeks of treatment, mean body weight (±standard deviation [SD]) was increased significantly from 59.82 ± 12.33 kg to 60.40 ± 13.38 kg in Group I (P = 0.01) and from 59.00 ± 12.36 kg to 60.33 ± 12.97 kg in Group II (P = 0.02). Mean BMI (±SD) increased significantly from 23.71 ± 4.69 kg/m2 to 24.10 ± 4.17 kg/m2 in Group I (P = 0.01) and from 24.00 ± 4.30 kg/m2 to 24.43 ± 4.59 kg/m2 in Group II (P = 0.02) during the study period. The mean BMI compared between two study groups (24.10 ± 4.17 vs. 24.43 ± 4.59) kg/m2 m+ after 12 weeks of treatment was not statistically significant (P = 0.816). About 64.0% of patients in Group I and 68.0% in Group II have shown weight gain and BMI change after 12 weeks. Mean HbA1c (±standard deviation [SD]) reduced significantly from 10.40% ± 2.17% to 7.76% ± 1.41% in Group I and from 10.41% ± 1.80% to 7.63% ± 1.37% in Group II. About 48.0% of patients in Group I and 56.0% of patients in Group II achieved glycemic target <7%. About 28.0% of patients in Group I and 20.0% of patients in Group II had hypoglycemia.

Conclusion:

From the current study, it can be concluded that both insulin regimens significantly cause weight gain, BMI change and also significantly effective in glycemic control. However, in comparison between the two groups, there was no significant difference. Hence, both premixed and glargine-based basal-bolus regimen can be prescribed as per patient need. This result may provide some preliminary information for further investigation

Context:

Positron emission tomography (PET) using F-18 fluorodeoxyglucose (FDG) for treatment monitoring in patients with lymphoma is one of the most well-developed clinical applications. Deauville five-point score (DS) is recommended for response assessment in international guidelines. DS gives the threshold for adequate or inadequate response to be adapted according to the clinical context or research question.

Aims:

We aimed to validate DS in Hodgkin's lymphoma (HL) by retrospectively assigning this score to F-18 FDG PET-computed tomography (CT) studies done before 2016 and analyzing its concordance with the line of management. The secondary aim was to assess the reproducibility of DS in the interpretation of PET-CT scans.

Subjects and Methods:

A total of 100 eligible consecutive patients underwent F-18 FDG PET-CT scans between January 2014 and December 2015. Their interim, end of treatment, and follow-up PET scans were retrospectively visually analyzed and assigned DS by three nuclear medicine physicians. Concordance was defined as agreement between the DS assigned and the line of treatment. Interobserver variability was calculated using weighted Kappa and presented with 95% confidence interval.

Results:

Among 212 scans assigned DS, 165 scans showed agreement between the DS and line of treatment. Of these, 95.2% of scans scored DS 1–3 were kept on following or the same treatment plan was continued and patients did well. Among the scans that showed discordance, 24 scans scored DS 4/5 were continued on the same treatment regimen and the next assessment showed disease progression.

Conclusions:

Our study confirmed that DS is a useful tool to aid in reporting F-18 FDG PET-CT in the management of HL with good positive and negative predictive values. This study also demonstrated good interobserver agreement.
Carnival Mask Sign on Bone Scan of Craniofacial Metastasis of Neuroblastoma
Authors: Hosokawa Takahiro , Uchiyama Mayuki
Published: February 2023

A craniofacial mass may cause the first clinical symptoms of malignancy. In pediatric patients, neuroblastoma, Langerhans cell histiocytosis (LCH), and acute lymphoblastic leukemia (ALL) are the most common diseases initially manifesting with bone lesions, and bone scintigraphy is a useful modality to evaluate them. The purpose of this pictorial essay was to show the scintigraphy findings of the craniofacial bones in three patients, with neuroblastoma, ALL, and LCH, and to provide a useful scintigraphic sign to differentiate these diseases. In the bone scintigraphy of neuroblastoma with craniofacial bone metastases, strong tracer uptake was evident, resembling a carnival mask. In contrast, in the two cases with LCH and ALL involving the craniofacial bones, the tracer uptake was lower than in neuroblastoma and with different distributions. Bone metastases of neuroblastoma usually occur in the periorbital craniofacial bones, and these metastases may be locally aggressive, destroying the bones; which show stronger uptake than other cranial bones. LCH is associated with varying degrees of disease activity, and its bone imaging findings differ based on its activity. Therefore, these lesions present low uptake in bone scintigraphy, showing as “cold spots”. Therefore, LCH scintigraphy of the craniofacial bones does not resemble a carnival mask. The bone marrow infiltration by leukemic cells usually shows as diffuse bone marrow. Therefore, in bone scintigraphy of leukemia, the tracer uptake in the periorbital craniofacial bones is similar to other cranial bones, not presenting as a carnival mask. In conclusion, bone scintigraphy to evaluate malignant craniofacial lesions could provide useful differential diagnostic information.

Introduction:

In this pilot study, we have proposed and evaluated pipelined application of the dynamic stochastic resonance (DSR) algorithm and block-matching 3D (BM3D) filter for the enhancement of nuclear medicine images. The enhanced images out of the pipeline were compared with the corresponding enhanced images obtained using individual applications of DSR and BM3D algorithm.

Materials and Methods:

Twenty 99m-Tc MDP bone scan images acquired on SymbiaT6 SPECT/CT gamma camera system fitted with low-energy high-resolution collimators were exported in DICOM format to a personal computer and converted into PNG format. These PNG images were processed using the proposed algorithm in MATLAB. Two nuclear medicine physicians visually compared each input and its corresponding three enhanced images to select the best-enhanced image. The image quality metrics (Brightness, Global
Contrast
Factor (GCF), Contrast
per
pixel (CPP), and Blur) were used to assess the image quality objectively. The Wilcoxon signed test was applied to find a statistically significant difference in Brightness, GCF,
CPP,
and
Blur of enhanced and its input images at a level of significance.

Results:

Images enhanced using the pipelined application of SR and BM3D were selected as the best images by both nuclear medicine physicians. Based on Brightness, Global Contrast Factor (GCF), CPP, and Blur, the image quality of our proposed pipeline was significantly better than enhanced images obtained using individual applications of DSR and BM3D algorithm. The proposed method was found to be very successful in enhancing details in the low count region of input images. The enhanced images were bright, smooth, and had better target-to-background ratio compared to input images.

Conclusion:

The pipelined application of DSR and BM3D algorithm produced enhancement in nuclear medicine images having following characteristics: bright, smooth, better target-to-background ratio, and improved visibility of details in the low count regions of the input image, as compared to individual enhancements by application of DSR or BM3D algorithm.
