Orbital metastases as the initial clinical manifestation of thyroid carcinoma
Authors: Mahyuddin Mutmainah , Theresia Kania , Anggraini Neni , Subekti H. Imam
Published: May 2024

Thyroid carcinoma rarely metastasizes to the orbit. Approximately only 2%–7% of orbital metastatic lesion were found originally from thyroid carcinoma. We present three cases to increase the awareness of orbital metastases as the initial manifestation of thyroid carcinoma. Three female patients aged 28–65 years old presented with initial complaint of orbital mass. Further examination discovered an asymptomatic lump on every patient's neck. However, one patient was unaware of her lump. Examination revealed that all lesions were metastases from papillary thyroid carcinoma. These cases conclude several similarities. First, prominent unilateral proptosis, orbital mass in the superior quadrant, limited eyeball movement, and orbital bone destruction were found in every patient. Second, all the orbital computed tomography scan showed extraconal solid masses involving adjacent structures and expanding intra-cranially or intrasinusly. These findings should raise one's suspicion of a metastatic lesion primarily caused by thyroid carcinoma. Despite the rarity of orbital metastases, thyroid carcinoma must be considered as a potential primary tumor in patients with initial presentation of orbital mass. Thorough physical examination is important to determine the origin of metastases.

Authors: Sharifi Mohammad , Es’haghi Acieh , Kiarudi Mohammad Yaser
Published: May 2024

BACKGROUND:

The aim is to investigate the change in aberrations following strabismus surgery in patients with horizontal strabismus.

MATERIALS AND METHODS:

This prospective study included patients who underwent surgery for horizontal strabismus. The patients were assessed preoperatively and 1 month and 3 months after the surgery, in terms of logMAR best-corrected visual acuity, eye deviation, spherical equivalent refractive error, tomographic and aberrometric corneal changes. Corneal tomography was performed using Orbscan II device. Wavefront analyses were performed using Bausch and Lomb Zywave II.

RESULTS:

A total of 25 patients (48 eyes) with exotropia or esotropia were entered in this study. Mean values of exotropia in the distance and near deviations were reported as 31.42 ± 7.13 and 28.82 ± 6.96 prism diopters (PD), respectively. Mean scores of esotropia in the distance and near deviations were 25.22 ± 5.41 and 30.45 ± 9.4 PD, respectively. Evaluation of irregularity in 5 mm zone, horizontal coma, spherical aberration changes, and root mean square of higher-order aberrations (HOAs) in 6 mm, and HOA w/o Z 400 changes showed that there was a significant difference before the intervention and 1 month after the surgery (P < 0.05). However, no difference was observed in the aforementioned variables before and 3 months after the intervention (P > 0.05).

CONCLUSIONS:

Results of the present study indicated a transient increase in HOAs and corneal irregularity following strabismus surgery on horizontal eye muscles that returned to the baseline after 3 months.

Published: May 2024

AIM:

The aim of this study is to determine the outcome of accommodative esotropia (ET) and influencing factors in young Omani children.

SUBJECTS AND METHODS:

In this retrospective cohort, children diagnosed with accommodative ET who had followed up in a tertiary hospital from 2006 to 2011 were identified. Parameters studied included cycloplegic refraction and its change with time, ocular alignment, binocularity, visual acuity (VA), amblyopia, and requirement for surgery.

RESULTS:

A total of 51 patients were identified. Twenty-four patients were diagnosed with fully accommodative ET (FAET) and 27 with partially accommodative ET (PAET). The mean (± standard deviation [SD]) age of onset and reporting were 2.6 (±1.58) and 3.2 (±1.84) years in the two groups, respectively. The mean (SD) cycloplegic refraction at presentation was 4.50 (±1.66) in the FAET group and 3.65 (±1.67) in the PAET group. Anisometropia was present in 28% of patients. The mean follow-up period was 4.9 years. The following were detected in the final visit. A reduction in amblyopia from 43% to 6% of patients, binocularity in 75% of patients, and a mean increase of 0.64 (±1.3) D in cycloplegic refraction from the first visit (P= 0.005). The mean angle of deviation at near and distance was 29.86 (±15.21) and 17.80 (±10.14) prism diopters, respectively, in FAET patients and 30.15 (±14.83) and 29.53 (±15.53), respectively, in PAET patients. Thirty-seven percent of the PAET patients underwent surgery within 5 years from diagnosis. All participants in this cohort continued to wear glasses in the last follow-up visit.

CONCLUSION:

Most children with refractive accommodative ET have an excellent outcome in terms of VA and binocular vision. The PAET group was characterized by delayed reporting, the presence of anisometropia, and lower hypermetropia. Further study is required to determine the possibility of weaning glasses in FAET patients.

Introduction: In root canal treatment, the glide path process

is considered

a primary action to increase the safet

y and efficiency of nickel–titanium rotary files and prevent preparation errors. The present study aimed to evaluate and compare different glide paths in terms of transportation and centering ability of the curved, narrow second mesiobuccal (MB2) canal of maxillary first molars using cone-beam computed tomography (CBCT).

Materials and Methods:

First, periapical radiographs and CBCT were obtained from extracted maxillary first molars, and 125 teeth, whose mesiobuccal root curve was in the medium range (a curve angle of 20°–40°) and had separate MB2 canal, were selected. However, teeth <17 mm and more than 21 mm in length were excluded from the study. Afterward, the access cavity was prepared with a round diamond bur, and the MB2 canal was negotiated using a manual size 6–8 C-pilot. In the next stage, were randomly divided to five groups of 25, and each group was prepared by using one of the files of ProGlider, R-Pilot, Hyflex EDM, WaveOne Gold Glider, and C-Pilot. Following that, CBCT was taken from all teeth again, and the levels of canal transportation and centering ability were evaluated at five levels (distances of furcation, 1 and 2 mm from the furcation, the crest of the curvature, and 1 mm from the apex).

Results:

In this study, there was no statistically significant difference in canal transportation and centering ability among five PathFile systems in all sections (P > 0.05).

Conclusions:

All five PathFile systems carry out Glide path preparation similarly and appropriately in terms of canal transportation and centering ability.

Published: May 2024

Introduction:

The important aspect of endodontic treatment is root canal irrigation. Although agitation systems proved to have enhanced irrigant wall interactions, syringe needle-based delivery systems still play a significant role during the preparatory phases of root canal treatment. The current study aimed to evaluate the time taken for the irrigant delivery during conventional syringe irrigation using different volume syringes in different root canal preparations.

Materials and Methods:

Two hundred extracted single-rooted premolars with approximately round canals were randomly instrumented to preferred apical preparation sizes using 0.4 tapered Hyflex-CM rotary Ni-Ti instruments and randomly divided as follows: Group I, instrumentation to size 40, 0.04 taper (n = 50); Group II, instrumentation to size 30, 0.04 taper (n = 50); Group III, instrumentation to size 25, 0.04 taper (n = 50); and Group IV, instrumentation to size 20, 0.04 taper (n = 50). Fifty operators were chosen for the experimentation. They were asked to irrigate the prepared specimens using different volume syringes. The entire irrigant delivery time was recorded by a head nurse using a stopwatch, and the values were calibrated and statistically analyzed.

Results:

Group I recorded significantly lesser time for irrigant delivery during manual syringe needle irrigation (P = 0.005) compared to other groups.

Conclusion:

Irrigation delivery time was less in 40/0.04 taper preparations, using 1 ml volume syringes.
Effective management of mandibular second premolar with root anomalies
Authors: Asiri Ashwaq Faia
Published: May 2024

The enigma of successful treatment of mandibular second premolars with taurodontism has been explored for very long due to its rarity of occurrence. This case report aimed to enumerate the successful nonsurgical endodontic management of left mandibular second premolar #35 with three roots and taurodontism. A 34-year-old Saudi male patient with a noncontributory medical history was referred from the prosthodontic department for nonsurgical root canal treatment of tooth #35. Clinical examination revealed rotated clinical crown with caries related to tooth #35. Pulp sensibility cold test of the tooth showed no response, with the absence of pain on percussion and/or visible pocket depth. Radiographic examination showed long and deep pulp chamber and rotated and curved roots with broken apical lamina dura. The tooth was diagnosed with necrotic pulp and asymptomatic apical periodontitis. After making an access to the pulp chamber, two orifices were easily detected while the third one was found by the aid of surgical microscope. The canals were cleaned and shaped using ProTaper Gold file and then obturated with BioCeram Sealer and Gutta-Percha points, using hydraulic bonded obturation technique. Tooth immediately received the final crown. Clinical and radiographical examination after a 3-month follow-up revealed successful peri-apical healing with no symptoms. A literature search was organized to review the past publications about management of mandibular second premolar with taurodontism or anomalies in the root canal system. The search was focused on cases reported in Medline, Scopus, and Google Scholar databases. The conclusion of the seven selected studies and reported cases revealed that proper visualization with advanced microscopes or computer imaging radiographs, negotiation of the root canals, and efficient instrumentation and obturation enhance endodontic success.

Published: May 2024

Introduction:

Root canal treatment (RCT) and its coronal restoration should be regularly assessed to ensure a successful treatment outcome. The aim of the current study is to evaluate the relationship between the obturation technical quality and coronal restoration in the clinical and radiographic outcome of RCT provided by Malaysian undergraduate students.

Materials and Methods:

A total of 143 root-treated teeth from 136 patients were evaluated through clinical examinations and periapical radiographs with a mean follow-up period of 2.4 (standard deviation = 1.59) years. The quality of the coronal restoration was classified according to modified United States Public Health Service criteria and the technical quality of the obturation was assessed based on two variables: length and density. Periapical status was evaluated according to periapical index scores.

Results:

About 64% of the teeth were classified as healthy with a significant reduction of apical periodontitis from 70.3% preoperatively to 36% at reassessment (P < 0.001). About 92.1% of obturation was of acceptable length, whereas 5% underfilled and 2.9% overfilled. Teeth with acceptable obturation length were five times less likely associated with apical periodontitis than the inadequately filled ones. 90% of canals had adequate obturation density with no significant association to apical periodontitis. Teeth restored with intracoronal restorations had 50% more chance of developing apical periodontitis. Inadequately restored teeth and teeth with poor obturation quality were associated with three times more likely apical periodontitis occurrence. The quality of endodontic treatment and the coronal restoration significantly influenced the periapical status (P < 0.001).

Conclusion:

The radiographic obturation quality and coronal restorations of the RCTs performed by the undergraduate students in a Malaysian public dental school were acceptable in 63.8% of cases with a 64% favorable outcome.

Extracellular vesicles: Function, resilience, biomarker, bioengineering, and clinical implications
Authors: Sun Der-Shan , Chang Hsin-Hou
Published: May 2024

ABSTRACT

Extracellular vesicles (EVs) have emerged as key players in intercellular communication, disease pathology, and therapeutic innovation. Initially overlooked as cellular debris, EVs are now recognized as vital mediators of cell-to-cell communication, ferrying a cargo of proteins, nucleic acids, and lipids, providing cellular resilience in response to stresses. This review provides a comprehensive overview of EVs, focusing on their role as biomarkers in disease diagnosis, their functional significance in physiological and pathological processes, and the potential of bioengineering for therapeutic applications. EVs offer a promising avenue for noninvasive disease diagnosis and monitoring, reflecting the physiological state of originating cells. Their diagnostic potential spans a spectrum of diseases, including cancer, cardiovascular disorders, neurodegenerative diseases, and infectious diseases. Moreover, their presence in bodily fluids such as blood, urine, and cerebrospinal fluid enhances their diagnostic utility, presenting advantages over traditional methods. Beyond diagnostics, EVs mediate crucial roles in intercellular communication, facilitating the transfer of bioactive molecules between cells. This communication modulates various physiological processes such as tissue regeneration, immune modulation, and neuronal communication. Dysregulation of EV-mediated communication is implicated in diseases such as cancer, immune disorders, and neurodegenerative diseases, highlighting their therapeutic potential. Bioengineering techniques offer avenues for manipulating EVs for therapeutic applications, from isolation and purification to engineering cargo and targeted delivery systems. These approaches hold promise for developing novel therapeutics tailored to specific diseases, revolutionizing personalized medicine. However, challenges such as standardization, scalability, and regulatory approval need addressing for successful clinical translation. Overall, EVs represent a dynamic frontier in biomedical research with vast potential for diagnostics, therapeutics, and personalized medicine.

With the development of network technology and intelligent application platforms, the "Three Precision" applet as a method of individual intervention for students' physical fitness can not only enable students to obtain the improvement of physical fitness and lifelong sports habits, but also establish a new bridge of cooperation between home and school. The analysis method of student physical fitness individual intervention assessment is affected by a variety of factors such as the framework design of the WeChat applet platform and the subjectivity of the intervention, which leads to the inefficiency of the student physical fitness individual intervention assessment method. To address this problem, we analyse the mode and content of students' physical fitness individual intervention based on the "Three Precision" applet, extract the feature vectors of students' physical fitness individual intervention, construct a system of students' physical fitness individual intervention assessment indexes, and establish a method of students' physical fitness individual intervention assessment based on big data technology and WeChat applet by combining the mushroom propagation optimization algorithm and convolutional neural network. Individual intervention assessment method based on big data technology and WeChat applet. The effectiveness and robustness of the proposed method are verified by using the data recorded in the "Three Precision" applet as the input data of the model. The results show that the proposed method meets the real-time requirements and improves the prediction accuracy of the individual intervention assessment method, which significantly improves the efficiency of the individual intervention assessment of students' physical fitness.

Understanding the structure of crust and shallow upper mantle beneath western Tibet through the joint inversion of Rayleigh wave group velocity dispersion with interpolated receiver functions
Authors: Das Ritima , Saikia Utpal , Saha Gokul Kumar
Published: May 2024

We present the 3-D shear wave velocity variationin the crust and upper mantle structure of western Tibet using a joint inversion of Rayleigh wave group velocity dispersion and interpolated receiver function. The lateral sampling of the receiver function and the surface wave dispersion is equalized by the interpolation scheme. This new method of spatial interpolation eliminates difficulties caused by back azimuthal variation in the receiver function. We have jointly inverted these interpolated receiver functions with the Rayleigh wave group velocity dispersions obtained from the earthquake and ambient noise tomography to map the tectonic structure of western Tibet. The study reveals remarkable variation of the seismic characteristics in the crust and shallow upper mantle of western Tibet. The mapped Moho depth is ~74 km in the northern part of the plateau, whereas it is ~69 km in the southern part. A thick mid-crustal slow-velocity zone from ~10km up to ~40 km depth has been observed, which could be attributed to partial melt. A noteworthy finding is the variation in slower crustal velocity between the south and north of the Lhasa Block (LB). We interpret this as the Indian crust that has been underthrusted beneath the Tibetan plateau, and the northern limit of the Indian lithosphere extends to the southern part of the LB.

Authors: Savović Slađana , Domanović Violeta , Jovković Biljana
Published: May 2024

A large number of studies have investigated the effects of acquisitions on the financial performance of the companies involved. Financial reporting plays a crucial role in understanding the effects of acquisitions on financial performance. An important aspect of financial reporting in acquisition processes is audit procedures that are carried out to confirm the reliability and truthfulness of financial reports. While research on the effects of acquisitions on financial performance is dominant in the academic literature, very little research has analysed the impact of acquisitions on companies' sustainability and ESG performance. Sustainable business practices are becoming increasingly important in today's corporate world. Companies realize that ESG (environment, social and governance) factors can have a significant impact on their long-term success and profitability. ESG factors are important in acquisition processes as companies face increasing scrutiny and pressure for transparency regarding environmental risk, social justice and corporate governance. The aim of the research in the paper is to look at the effects of acquisitions on the financial and ESG performance of companies. The research was conducted on the example of Siemens Mobility, which was created by the acquisition of the Serbian company Milanovi? Inženjering by the German company Siemens. Financial statements of the company in the years before and after the acquisition, reports on the sustainability of the company, as well as other relevant documents were analysed. The special contribution of the work is reflected in the comprehensive overview of the effects of acquisitions on ESG performance of companies.

Published: May 2024

The retail sector with its network of stores is an inseparable and one of the most important parts for the functioning of the economy and society in general in the modern dynamic market environment. This is particularly evident when it comes to the retail sale of fast moving consumer goods (FMCG). The fact is that the vast majority of the population does not produce food and other existential goods for daily consumption, but is completely dependent on the purchase of these products. Considering this, it is clear that any major turbulence caused by a certain crisis that directly or indirectly affects retail sector also affects consumers’ life quality. Crises, such as those caused by the COVID 19 pandemic, lead to product shortages on the shelves, reduced opening hours of the stores, closure of stores in many locations, changes in the assortment of stores, increase in prices of products on retail shelves, longer waits for product delivery, less employees in the stores that are available to consumers, etc. If the global events that caused crises on market in the recent past have shown as anything, it is that crises will be more and more frequent, with an unpredictable length and even faster expectations for adjustments to market conditions in order to persist and remain competitive. The objective of this research is to look at the impact of these crises and their consequences on retailers and consumers, in order to predict new crises and make suggestions so that retailers can react to mitigate the effects of these crises.
Event-Driven Analysis of the Effectiveness of European Economic Sanctions Against Russia (2022–2024)
Authors: Chernykh Aleksandr
Published: May 2024

This paper examines the effectiveness of European economic sanctions against Russia from 2022 to 2023, with a focus on the impact of these measures on the Russian oil & gas sector. Prior to the implementation of large-scale sanctions, the European Union was Russia's principal trading partner. Against this backdrop, this study assesses the impact of European restrictions on Russia. Utilizing the event analysis method, renowned for its reliability in assessing the effects of anti-Iranian sanctions and previous sanctions against Russia during 2014-2021, this research analyzes data from the oil & gas sector of the Russian stock market on the Moscow Exchange. Despite significant attention to oil exports from the sanctions imposers, findings indicate a minimal impact on the oil and gas sector. The study aims to shed light on the economic ramifications of these recent sanctions and seeks to contribute to the broader discourse on the efficacy of economic sanctions as a tool of foreign policy.

Authors: Đokić Danilo , Matkovski Bojan , Jurjević Žana
Published: May 2024

In scientific research in the field of agricultural economics, in the last decade, the ecological effect of the use of chemical inputs has been increasingly in focus. Changes within the EU's Common Agricultural Policy, stimulated by the European Green Deal, contributed significantly to this trend. Following the above, the goal of this research is to determine the effect of mineral fertilizers on the output in different lines of crop production in South Ba?ka District. The FADN database was used in the work. The results showed that using mineral fertilizers is a significant factor in crop production. Also, a positive correlation between the use of mineral fertilizers and yield was identified in the production of corn and soybeans. In contrast, a negative correlation was present in the case of wheat and sunflower production. The negative correlation suggests that the mineral fertilizer was used suboptimally and that weather conditions significantly affected this production and prevented the absorption of nutrients. In addition, there are nitrogen surpluses, which threaten the environment. The estimated losses are 26 tons of nitrogen.

Published: May 2024

The EU integration process brings substantial transformations across all economic domains, agriculture included, as a result of shifts in both the economic and political landscapes. These processes necessitate numerous adjustments to legislation, agricultural support structures, business conditions within the single market, and the harmonization of domestic producer prices with those prevailing in the EU market. The impacts of these changes can be assessed utilizing partial equilibrium models such as the AGMEMOD model. While this paper primarily lays the methodological framework for constructing the Serbian national AGMEMOD model, upon its completion, it could serve as a valuable instrument for evaluating the effects of political changes on agricultural markets in Serbia, aligning with the evidence-based policy principle, similar to other EU member states

Childhood – a children’s literature journal (Detinjstvo – časopis o književnosti za decu) has been published continuously since 1975 in Novi Sad in the Zmaj’s Children’s Games (Zmajeve dečje igre) edition. During its half a century of existence, six editors-in-chief and many more editorial teams have changed. On the pages of Childhood, texts of different nature were published, but all of them were dedicated to children’s literature and childhood, examining their various aspects. This text shows how criticism, evaluation of works of literature for children, actually evaluates the recipient itself, that is a child. It is also shown how the attitude towards the language of the literary work reflects the understanding of the child’s overall development, not only speech development. Insights into childhood and the child in older literature (for example, medieval) and oral tradition lead to a conclusion about the position of the child during the historical development of society. The image of childhood and children in different genres and in the works of different writers is most common on the pages of Childhood. It goes from the vision of an “ideal times” in which the “ornament of the world” flourishes, to the representation of a lonely child, left to itself and the terror of a consumer society in which it has the status of a “suppressed group”. The paper provides a broad framework that includes the concept of a child and childhood in a series of variations that are difficult to encompass. In such a widely covered synchronic and diachronic understanding of the child and childhood, in the Yugoslav, South Slavic and Serbian regions, but also in constant communication with general movements and knowledge, in the texts of different preoccupations (program texts, literary criticism and presentations, didactic texts), concepts of the child as an unfinished being and the child as an ideal and idealized projection of humanity are clearly observed, but also observed are the general value system of the culture, the national culture above all, and the culture of Western civilization with its essentially ambivalent attitude towards the child and childhood.

Published: May 2024

In the past half a century, dozens of female and male writers have published their papers in the journal Childhood, among them were texts belonging to the field of critical and theoretical reading of literature for children. Suggesting several open fields for further research of everything the phrase “writers as critics” entails, this paper gives and overview of contextual frames and types of contributions from this group of associates. Regardless whether they were intentionally written for this journal, whether they were included in the themes and thematic blocks, permanent or temporary sections, whether they are experiments, studies, essays, demonstrations, comments, reflections, interviews, translations – all texts from the abovementioned corpus are regarded as equally valuable, and even crucial in the creation of the structural diversity and dynamic of Childhood.
ENCODING LOVE IN CHILDREN’S POETRY
Authors:   Josip Juraj Strossmayer University of Osijek, Faculty of Education, Croatia, Živković Zebec Vedrana A.

Children’s poetry is oriented towards the child’s experience of the world, encompassing themes of play, nature, homeland, emotions, and others. It follows the emotional, interest, and cognitive development of the child, and themes and motifs in children’s poetry are incorporated differently depending on the age of the implicit readers, as observed in poetry with themes of love. Children’s love poetry includes various manifestations of love, from so-called partner love, through thematizing family emotions to love for friends, animals, homeland, etc. In the study, Luhmann’s communication concepts of love coding were applied to the selected corpus of Croatian children’s and adolescent love poetry that thematizes so-called partner love, and the models of love coding were observed as idealization, paradox, incommunicability, and romantic coding of love. The idealization model recognizes beauty and virtue as what attracts lovers, but it also extends to accepting imperfect aesthetic characteristics and flaws. The paradox as a communication model implies communication models that provoke contradiction by displaying emotions in unexpected and inappropriate ways or by diminishing the lover’s abilities and comparing love to illness. Lyrical subjects demonstrate the inability or avoidance of expressing emotions, which can lead to communication breakdown or its absence, and such a communication model is observed as a model of incommunicability. Codes of romantic love tend towards the privacy of lovers and encompass gestures and occasional verbalization. Different codes can intertwine and complement each other in individual poems.
THE SIGNIFICANCE OF FRIENDSHIP AND LONELINESS IN PEER RELATIONSHIPS, SHOWN IN MACEDONIAN LITERATURE FOR CHILDREN AND YOUTH

Humans are social beings for whom social communication with other people is vital. Usually, when the word “loneliness” is mentioned, the first association is related to older people, or people of an advanced age. But the fact is that loneliness cannot be linked specifically to a certain age in a person. Neither children nor adolescents are an exception to that. Adolescence is a period of transition, in which young people face many new challenges, both in their family and at school. Hence, it is crucial for the young man to have harmonious relations in his family, and especially to establish friendly relations at school, in places where young people go out, etc. In this way, friendship with peers can relieve them of the stress related to school, grades, appearance that changes “overnight”, etc. In this article, we refer to those few key moments, through appropriate examples that we will extract from contemporary Macedonian literature for children and youth.
