Authors: Aljehani Dareen K.
Published: April 2024

ABSTRACT

Background:

The capacity to grasp and recognize one’s own and human feelings, use cognitive awareness to control actions and behavior, and modify moods in response to difficult situations is known as emotional intelligence (EI). Perceived stress has been linked to higher levels of depression among healthcare students. This study set out to assess EI, perceived stress (PS), and life quality assessment (LQA) among dental undergraduates and to ascertain how these factors are linked to one another.

Materials and Methods:

The self-reported cross-sectional research was organized among preclinical and clinical years of dental students to examine their emotional intelligence and stress-coping capacity. About 146 students participated in the study, with ages ranging from 19 to 25, irrespective of gender. The students were given the Schutte Emotional Intelligence and Perceived Stress Scale tools (PSS10) by Cohen, and with World Health Organization Quality of Life (WHOQOL-BREF) tool examined the characteristics that contribute to life quality among students.

Results:

The study included 146 individuals, 38 males (26.02%) and 108 females (73.97%), with an unresponsiveness rate of 2.66%. The correlation revealed statistically high significance among emotional intelligence and perceived stress (P = 0.000), perceived stress and life quality (P = 0.02), and emotional intelligence and life quality (P = 0.008). The statistical analysis of the influence of EI, PS, and LQA on academic year-wise analysis determined non-significant (P > 0.05).

Conclusion:

Due to the time constraints of their job, dentistry training may be highly stressful, yet regular evaluations of student performance and the accompanying factors would help us to understand how students behave in challenging circumstances.

Published: April 2024

ABSTRACT

Aim:

To evaluate the effect of lasers on the shear bond strength of Giomer and G-aenial flo composite using three different etching techniques.

Materials and Methods:

60 Samples (extracted human premolar teeth) are cut horizontally using a diamond disk to expose a flat occlusal surface involving enamel and dentin. On exposed occlusal surfaces, etching is done by various methods. These were divided into six groups of ten samples each as follows: group I (acid etched for Giomer), group II (acid etched for G-aenial flo composite), group III (laser etched for Giomer), group IV (Laser etched for G-aenial flo composite), group V (air abrasion etched for Giomer), group VI (Air abrasion etched for G-aenial flo composite). Then, restorative material is placed and cured with light for 20 seconds. The samples were thermocycled to simulate the oral environment. The samples were subjected to a universal testing machine for bond strength testing at a cross-head speed of 3 mm/min until the restoration will fracture.

Results:

The intergroup comparison between both the materials using Student’s t-test gives insignificant results. The intergroup comparison between different etching techniques using two-way ANOVA tests gives insignificant results.

Conclusion:

Within the limitation of this study, it can be concluded that Giomer and G-aenial flo composite achieved the same shear bond strength in all the etching techniques.

ABSTRACT

Introduction:

In pediatric dentistry, the esthetically pleasing materials have tremendously changed the concept of restorative practice.

Aim and Objectives:

1. The aim of the study is to evaluate the effect of child health drinks on color stability of various esthetic restorative materials via spectrophotometric analysis and to identify the esthetic restorative material that is color-stable against child health drinks.

Materials and Methods:

A total of 120 disk-shaped specimens with a diameter of 12 mm and a thickness of 2 mm were made from a composite (Dyract), giomer (Shofu), and composite (GC). Each group of 40 specimens of each material was divided into four sub-groups. Each sub-group was stored in different solutions, distilled water, Bournvita, Horlicks, and Pediasure, for 60 days. The color change measurement was done using a spectrophotometer both before and after staining.

Result:

One-way analysis of variance depicted that when the ΔE values of the restorative material were tested against each of the child health drink, there was a statistically significant difference between all child health drinks (P < 0.00001). When restorative materials were compared with the staining agent on 60 days duration, except Pediasure and Control, others (i.e. Horlicks and Bournvita) showed a statistically high significance (P < 0.05).

Conclusion:

Bournvita caused the highest color changes in 60 days time interval, followed by Horlicks and Pediasure. When the discoloration of several materials is studied, the highest level of discoloration was observed in the compomer, followed by the giomer, and the lowest level in the composite.

Published: April 2024

ABSTRACT

Tooth movement in orthodontic therapy is connected to the frictional force that is created as the wire passes over the bracket. It is possible for teeth to move quickly when friction is at a minimum. Wires coated with nanoparticles have been found to reduce friction as a result of current developments in the orthodontics sector. Having an antimicrobial property is an added benefit. To reduce the friction generated by brackets, wires, and bands by lessening their cytotoxicity, this study examines the potential use of TiO2 nanoparticles in orthodontics. A monolayer of L929 was utilized in an indirect cytotoxicity test to evaluate the cytotoxicity of the coated orthodontic wire. The absence of reactive zones in our sample data demonstrates that TiO2 is not cytotoxic. Considering the results of our study, we conclude that TiO2 is secure for use as a coating for orthodontic devices.

Published: April 2024

ABSTRACT

Introduction:

Smokeless tobacco (SLT) has been linked with various oral signs and symptoms, such as oral mucosal lesions and gingival and periodontal effects. However, there is limited research on the prevalence of SLT use and its impact on gingival and periodontal health in the adult population of the Emirates of Sharjah.

Aim:

To assess the prevalence of SLT consumption and its effects on gingival and periodontal health in the adult population of the Emirates of Sharjah.

Methods:

The study evaluated 171 dentate patients aged 18–77 years who use SLT or are nonsmokers. Data were collected through a questionnaire on SLT use and periodontal health assessed using plaque index, gingival index (GI), attachment score, and gingival recession (GR). Statistical analysis was done using SPSS 27.0 version.

Results:

Among 390 screened participants, 28 subjects (21 males and 7 females) were SLT users with prevalence of 7.18%. No significant differences were found in plaque index, GI, or periodontal pocket depth. However, SLT users had significantly higher clinical attachment loss scores (mean 4.01 mm, SD 0.35) compared to non-users (mean 1.49 mm, SD 1.12). Significant differences were also observed in GR.

Conclusions:

This study provides insights into the prevalence and impact of SLT use on periodontal and gingival health in UAE adults. SLT usage is associated with a higher risk of periodontitis and gingivitis, indicating the need for awareness and intervention. Further research is required to validate results and consider confounding factors.

Published: April 2024

ABSTRACT

The global lockdowns have resulted in the popularisation of tele-consultation. Also the anxiety about dental visits and hospital-acquired infections in patients and incidences of dishonesty are increased. Tele-consultation includes patient data collected on phone calls, text messages, and video calls. Bluffing or providing false information is one of the dark realities of clinical practice. Dishonesty might affect the treatment success and spread of contamination. During normal and epidemic eras, skills for honesty and bluff identification are required during tele-consultation to protect patients and doctors from hospital-acquired infection in further one-to-one treatment meetings.

Authors: Al-Essa Aiad
Published: April 2024

ABSTRACT

Background:

Descemet membrane endothelial keratoplasty (DMEK) has been utilized more frequently during recent years to treat penetrating keratoplasty (PKP) graft failures. The perioperative evaluation technique of anterior segment optical coherence tomography (AS-OCT) is increasingly significant. Our goal is to discuss DMEK surgical and clinical for subsequent PKP graft failure, along with significant surgical modifications and adjustments in accordance with preoperative assessment utilizing AS-OCT.

Materials and Methods:

Patients’ records who performed DMEK for PKP failure were retrospectively reviewed. Demographic information, PKP graft size determined by postoperative problems, corneal donor endothelial cell density (ECD), AS-OCT, central pachymetry, visual acuity (VA) evaluated in Snellen units, intraoperative surgical procedure modifications, and postoperative ECD were all included in the data collection.

Results:

The observation was conducted with 16 patients with 16 eyes, nine males and seven females. The observation period is 18 months. DMEK was performed at an average age of 63. Preoperative AS-OCT was performed on all patients, and based on cases, surgical plans were created. Before processing DMEK, the mean VA is 0.04, and central pachymetry is 685 m. They improved considerably to 0.3 (P value = 0.001) and 542 m (P value = 0.008) at the most recent follow-up. About 93.75% of the grafts were adhered to after the procedure. Late decompensation caused a 6.25% graft failure rate. Graft detachment rates and cases requiring rebubble rates were respectively 18.75%.

Conclusion:

In DMEK for failed PKP, a good case-specific preoperative assessment by AS-OCT is essential. As a result, it relies on developing a surgical strategy that can improve surgical outcomes, lower the risk of complications, and quicken visual recovery.

Published: April 2024

ABSTRACT

Background:

To assess and contrast the depth of penetration of conventional calcium hydroxide, nanoparticle calcium hydroxide, silver nanoparticles, and combination of nanoparticle calcium hydroxide and silver nanoparticles into dentinal tubules using confocal laser scanning microscope.

Materials and Methods:

Eighty human single-rooted teeth were decoronated and instrumented up to Protaper Universal F3. Teeth were separated into four groups at random (n = 20) following chemomechanical preparation. Group 1: Control Conventional Calcium Hydroxide; Group 2: Nanoparticle Calcium Hydroxide; group 3: Silver Nanoparticles; group 4: Combination of Nanoparticle Calcium Hydroxide and Silver Nanoparticles. With the use of lentulo spirals, medications were injected into the canals, stirred up with ultrasound, and then kept at 37°C for 24 hours. A 1 mm thick slice was obtained at 5 mm from the root apex by sectioning the root perpendicular to the long axis of the tooth and then put on a glass slide to measure the depth of penetration using a confocal laser microscope.

Statistical Analysis:

To quantify the depth of penetration among the four groups, a one-way ANOVA was used and post hoc–Tukey’s test was used to compare between groups.

Results:

All of the groups were statistically significant, with group 4 showing the greatest depth of penetration, followed by group 2 and group 3. In contrast, all other groups in the intergroup comparison were statistically significant (P value 0.05) aside from the comparison of group 2 to group 3.

Conclusion:

Silver nanoparticles and nanoparticle calcium hydroxide together demonstrated greater penetration than calcium hydroxide, silver nanoparticles, and nanoparticle calcium hydroxide alone.

ABSTRACT

Oral submucous fibrosis (OSF) is a chronic disorder prevalent in South and Southeast Asia and is mainly related to the habit of chewing betel quid. Although there are numerous South-Asian studies about OSF, there is no study that evaluates the awareness of OSF among expatriate populations of South-Asian origin. Evaluated the awareness of OSF among South-Asian expatriate patients reporting to a dental hospital in Sharjah. Prevalidated questionnaires were given to 150 expatriate patients of South-Asian origin with quid-chewing habit reporting to the teaching clinics of a dental hospital in the United Arab Emirates. Among the 150 patients, 103 responded to the questionnaire. Among the 103 respondents, 11.65% were aware of OSF. Respondents living in shared residency and labor camps had significantly (P = 0.43) lower awareness of OSF compared to respondents living with their families. The results of our study show that the awareness of OSF is lower among the respondents living in labor camps and shared residencies. The younger respondents had more awareness of OSMF and were more likely to quit the quid-chewing habit.

Authors: Bhutia Karma L. , Upreti Benoy , Sarda Rohit K. , Shila Poonam
Published: April 2024

ABSTRACT

Background:

Pregnancy-Induced hypertension (PIH) is a common health problem that occurs during pregnancy and may lead to limited fetal growth and other major health problems. Being a serious public health issue, PIH is responsible for a significant number of deaths across the globe. Hyrtl’s anastomosis of the umbilical arteries and placenta is a blood vessel system that can affect the growth and development of the fetus. The studies conducted earlier have suggested that the abnormalities in Hyrtl’s anastomosis may be associated with the development of PIH and other adverse pregnancy outcomes.

Aim:

The aim of the current systematic literature review is to investigate the potential advantages and restrictions of Hyrtl’s anastomosis as a medical diagnosis and treatment tool for PIH by reviewing the available evidence.

Materials and Methods:

The current study is a systematic literature review that involves the selection of 10 articles published in or after 2019 from reputed journals that evaluated the effectiveness of Hyrtl’s anastomosis in PIH. The inclusion criteria for this review are as follows: studies that involved human subjects, were published in English, were randomized controlled trials, case-control studies, observational studies, or systematic reviews, and evaluated the effectiveness of Hyrtl’s anastomosis. The exclusion criteria are as follows: studies published in other languages did not involve human subjects and did not measure the effectiveness of Hyrtl’s anastomosis in PIH. The search strategy includes a comprehensive search of the relevant databases using keywords related to Hyrtl’s anastomosis, umbilical artery, placenta, and PIH. Both data collection and analysis were conducted when the authenticity and validity of the articles used in this study were maintained. Data extraction was carried out by identifying the key findings of the articles selected for review in this particular study. The quality of the studies included in this review was assessed based on the JADAD scale.

Findings and Conclusion:

The aim of the systematic literature review is to evaluate the effectiveness of Hyrtl’s anastomosis in the detection and management of PIH. The current study design involved the selection of 10 articles published in or after 2019, with inclusion and exclusion criteria defined for the selection process. The search strategy included a comprehensive search of relevant databases. Both data collection and analysis were conducted when the authenticity and validity of the chosen articles were maintained. The quality of the studies included in the review was assessed based on the JADAD scale.
Fosfomycin Susceptibility among Extended-spectrum βeta Lactamase (Esbl)-Producing Escherichia coli and Klebsiella pneumoniae Isolates Causing Uti in a Tertiary Care Center in Western India
Authors: Kumbhar Shrutika R. , Babu Aishwarya , Modak Meera S.
Published: April 2024

ABSTRACT

Context:

At present, commonly encountered infections like urinary tract infections (UTIs) are becoming more and more difficult to treat. UTIs caused by extended-spectrum β-lactamase (ESBL) organisms tend to lead to uncertain outcomes and prolong hospitalization as these organisms are multidrug resistant. Such a situation has forced clinicians to reconsider the use of old antibiotics like fosfomycin.

Aims:

To determine fosfomycin susceptibility among ESBL-producing Escherichia coli and Klebsiella pneumoniae isolates causing UTI in a tertiary care center in Western India.

Settings and Design:

This is a cross-sectional study done in the Department of Microbiology between July 2021 and July 2022.

Methods and Material:

Urine samples from all outpatients and inpatients with suspected UTI which were received in the microbiology laboratory were inoculated in appropriate culture media. Pure growth of bacteria with a significant colony count was identified and antibiotic susceptibility testing was done as per standard guidelines.

Statistical Analysis Used:

The collected data were entered in a Microsoft Excel sheet and analyzed.

Results:

A total of 437 urine samples were collected from which 39 isolates of ESBL E. coli and 10 isolates of ESBL Klebsiella pneumoniae were obtained. All the E. coli isolates were sensitive to fosfomycin, while two of the Klebsiella pneumoniae isolates were resistant to fosfomycin.

Conclusions:

Older antibiotics like fosfomycin and nitrofurantoin attain high concentrations in the urinary tract, have a minimal impact on gastrointestinal flora, and do not develop resistance as compared to many other antibiotics. Therefore, fosfomycin should be preferred for the treatment of uncomplicated UTIs caused by resistant strains.

Published: April 2024

This study examined the relative proportion of enteric pathogens associated with severe gastroenteritis (GE) among children younger than 2 years in a phase III efficacy trial of the ROTASIIL® vaccine in India, evaluated the impact of co-infections on vaccine efficacy (VE), and characterized the association between specific pathogens and the clinical profile of severe GE. Stored stool samples collected from cases of severe GE in the phase III trial were tested by quantitative polymerase chain reaction using TaqMan™ Array Cards. Etiology was attributed by calculating the adjusted attributable fraction (AF) for each pathogen. A test-negative design was used to estimate VE. The pathogens with the highest AFs for severe diarrhea were rotavirus (23.5%), adenovirus 40/41 (17.0%), Shigella spp./enteroinvasive Escherichia coli, norovirus GII, enterotoxigenic E. coli, and Cryptosporidium spp. A considerable proportion of the disease in these children could not be explained by the pathogens tested. Severe GE cases associated with rotavirus and Shigella spp. were more likely to have a longer duration of vomiting and diarrhea, respectively. Cases attributed to Cryptosporidium spp. were more severe and required hospitalization. In the intention-to-treat population, VE was estimated to be 43.9% before and 46.5% after adjustment for co-infections; in the per-protocol population, VE was 46.7% before and 49.1% after adjustments. Rotavirus continued to be the leading cause of severe GE in this age group. The adjusted VE estimates obtained did not support co-infections as a major cause of lower vaccine performance in low- and middle-income countries.

Published: April 2024

In this paper, experimental studies were conducted to examine the mechanical
behavior of a polymer composite material called polyamide with glass fiber
(PA6-GF), which was fabricated using the three-dimensional (3D) fusion
deposition modeling (FDM) technique. FDM is one of the most well-liked low-cost
3D printing techniques for facilitating the adhesion and hot melting of
thermoplastic materials. PA6 exhibits an exceptionally significant overall
performance in the families of engineering thermoplastic polymer materials. By
using twin-screw extrusion, a PA6-GF mixed particles made of PA6 and 20% glass
fiber was produced as filament. Based on literature review, the samples have
been fabricated for tensile, hardness, and flexural with different layer
thickness of 0.08 mm, 0.16 mm, and 0.24 mm, respectively. The composite PA6-GF
behavior is characterized through an experimental test employing a variety of
test samples made in the x and z axes. The mechanical and physical
characteristics of PA6-GF polymer were examined using tensile, flexural, and
impact tests. The best outcomes were obtained for specimens printed with 0.08 mm
lower value of layer height, which had a greater impact on all mechanical
performance. The replacement of traditional materials was suggested with this
high-strength printed samples in industrial application products.

Le modèle Mover-Stayer, une généralisation du modèle de chaine de Markov. Ce modèle suppose l’existence de deux types d’individus, ceux qui restent dans leur état initial tout au long de la période d’observation, ces individus sont appelés «Stayer» et d’autre individus appelées «Mover», dont les changements de position dans le temps suivent un processus de Markov de premier ordre avec une matrice de transition appelée M. Ce modèle est appliqué à l’évolution des performances pédagogiques des 48 wilayas à l’examen national du baccalauréat sur la période 2008-2018. Il permet d’estimer les probabilités de transition entre les différents niveaux de performance (niveaux A, B, C) des wilayas mobiles («Moving») et la proportion de celles qui se maintiennent dans leur niveau de réussite de départ «Stayer» tout au long de la période d’observation. Nos résultats révèlent que la généralisation du modèle de Markov peut conduire à des modèles plus précis d’aide à la décision dans le secteur de l’éducation.
OPTIMIZATION OF INVESTMENT SUPPORT FOR THE WASTE MANAGEMENT SYSTEM FOR ENERGY

Published: April 2024

Investing in waste management is a clear example of the concept «for one man's garbage is another man's treasure». Many investors value the reliability of revenue generation from waste management, especially in the post-pandemic context. Waste management is considered a crucial business segment. In this case, in 2020, the global waste market was worth $1.6 trillion. These figures are expected to reach $2.5 trillion by 2030. Experts estimate that by 2050, the amount of global waste will have increased to 3.74 billion tons. This waste commonly accumulates in high-income countries, which produce around 34% of the world's waste. In the growing waste management crisis context, the importance of this issue goes beyond just collecting and disposing of waste. Effective waste management is increasingly becoming a pivotal element in safeguarding the planet's health. Innovations in waste management are implemented at the current stage and play a critical role in supporting sustainable materials management and reducing the impact of climate change. Waste management encompasses a range of strategies and processes aimed at reducing its volume. The same as in any business, seasonal fluctuations affect waste management. For instance, the quantity of construction-related waste decreases in winter as construction slows and increases in the warmer months when construction activity increases. The need for garbage collection also increases after storms. Investors analyzing funds that incorporate waste management can recognize and anticipate patterns related to these events. Converting waste to electricity and heat is a method by which municipal waste management systems have contributed to reducing the use of coal fuels and mitigating the impact of landfill gas. Methane collected at landfills can be used as a fuel source, helping to reduce the negative influence of emissions from landfills and providing an additional energy resource. Waste management revenues typically remain resilient even during economic downturns. The pandemic has caused losses to numerous enterprises, but compared to airlines, cruise lines, and restaurants, large waste management companies have experienced less impact. It can be explained by the fact that larger companies can develop several sources of income. For example, the demand for waste from industry and business may have decreased during the pandemic, but the amount of household waste has exponentially increased. It is worth noting that technologies for energy production from waste have emerged as an alternative solution for solid waste treatment. Waste-to-energy systems provide significant environmental and economic benefits by converting waste into affordable energy, which is a major part of an integrated solid waste management strategy.

In Ukraine, as in many countries worldwide, territorial communities are grappling with the challenges and opportunities presented by the digital age. The rapid advancement of digital technologies offers immense potential to enhance the efficiency, transparency, and inclusivity of local governance, as well as to stimulate economic growth and improve the quality of life for residents. However, harnessing this potential requires strategic vision, proactive policies, and robust infrastructure to ensure that no community is left behind in the digital revolution. This article explores the key global trends of digitalization and examines their implications for the development of territorial communities in Ukraine. By analyzing case studies, best practices, and emerging challenges, we aim to provide insights into how local authorities, businesses, and civil society can leverage digital technologies to build more resilient, dynamic, and prosperous communities in the 21st century. From smart cities initiatives to digital inclusion programs, the journey towards a digitally empowered future begins at the local level, where innovation and collaboration are essential drivers of progress.

In the publication, a comparative analysis of factors influencing the reproduction of colors on material media by modern technologies and means is carried out. Despite the significant successes of color reproduction technologies, the rapid development of technology and serious progress in science, several objective reasons take place in the reproduction process, due to which, as a rule, it is not possible to reproduce on a print all the variety of colors that a person is capable of perceiving. Based on the built model of the importance of factors, the most significant reasons affecting the final result were identified. The work presents the means that are used to achieve the maximum possible equality of the colors of the original and the colors of the reproduction. Based on the conducted experimental research and mathematical modeling, it was concluded that high-quality color reproduction is still not an easy task today due to a large number of influences in the process of converting color information. There are many factors that cannot be changed, such as the characteristics of consumable materials or the pressing of a raster dot during the printing process, but taking into account the specifics of a specific printing process during color separation and the manufacturing process of printing forms allows you to significantly improve the result of color reproduction. The method of determining the optimal thickness of the paint layer of printing inks to reduce the negative impact of printing process factors on the quality of color reproduction on the print is described.

Published: April 2024

Real estate management systems are crucial for efficiently handling property transactions, ownership records, and regulatory compliance in the real estate industry. However, traditional real estate management systems face challenges related to security, transparency, and trustworthiness, leading to issues such as fraud, disputes, and inefficiencies. This paper explores the application of blockchain for secure real estate management systems, focusing on its potential benefits, implementation challenges, and use cases. Smart contracts have a superb advantage for avoiding fraud cases and instilling behaviour among the stakeholders of the system. We examine how blockchain can enhance security, streamline processes, reduce fraud, and improve trust in real estate transactions by providing a decentralized and tamper-proof platform for recording and verifying property ownership, contracts, and transactions. Additionally, we discuss the technical considerations, regulatory implications, and adoption barriers associated with implementing blockchain-based real estate management systems. This paper advocates a trustful mechanism for securing online transactions in the modern-day real estate marketplace.
La violencia psicológica: el abandono de la víctima y sus consecuencias jurídicas en el cantón La Troncal año 2021
Authors: Ruiz Castro Ruth Cecilia , Gómez de la Torre Jarrín Gina Lucía
Published: April 2024

El Código Orgánico Integral Penal tipifica la violencia psicológica como delito y concede a las víctimas el derecho de denunciar ante las autoridades pertinentes. Sin embargo, la experiencia post-denuncia muestra un tratamiento revictimizante, donde las víctimas se ven obligadas a repetir los eventos traumáticos, reviviendo la agresión y experimentando emociones y ansiedad, lo que a menudo resulta en la retirada de la denuncia. La deserción de las víctimas durante la investigación y el proceso judicial es una situación común. Este estudio se enfoca en analizar la literatura doctrinaria, el marco jurídico, comparaciones internacionales y encuestas a servidores judiciales para entender las causas del abandono del proceso por parte de las víctimas. Los hallazgos preliminares sugieren que la revictimización durante la denuncia y el proceso judicial es un factor clave, junto con deficiencias en el sistema judicial en términos de apoyo y protección a las víctimas. Se destaca la necesidad de abordar la revictimización para mejorar el apoyo y la participación de las víctimas, lo que requiere una revisión de los procedimientos legales y una mayor sensibilización entre los servidores judiciales para garantizar un proceso justo y empático, reduciendo así la tasa de deserción y promoviendo la justicia para los afectados por este delito.
