Objectives: Liver transplantation (LT) is the main therapy for patients with cirrhosis or fulminant liver failure. However, there is a disproportion between the demand and availability of organs, such that the waitlist mortality ranged from 20 to 38% when the only allocation criterion was the time of inclusion on the waitlist. Brazil then adopted the Model for End-stage Liver Disease (MELD) score, aiming to prioritize patients with a higher risk of death for LT. !erefore, this study aimed to determine factors associated with waitlist time for LT. Methods: Retrospective cohort study of adult patients listed for LT from October 2012 to December 2019 in a single state in Brazil. Results: !e study analyzes 1,262 patients (869 males, 68.91%; median age, 53.33 ± 11.48 years; median waitlist time, 103.88 ± 162.05 days; median MELD Sodium [MELD-Na] score of 22.41 ± 6.09). Alcoholic liver cirrhosis (n = 369; 29.24%) and chronic viral hepatitis (n = 295; 23.38%) were the most prevalent reasons for LT. Blood groups O (n = 534; 42.31%) and A (n = 474; 37.56%) prevailed among the recipients. !e state capital and its metropolitan region accounted for 91.20% (n = 1,151) of all liver transplants performed. Most donors were deceased (n = 1,258; 99.68%). Patients with MELD-Na scores > 21 (p < 0.001), non-O blood group (p = 0.002), age < 53 years (p = 0.003), and those listed ≥ 2017 spent ≤ 30 days on the waitlist (p < 0.001). Conclusion: A waitlist period of ≤ 30 days was associated with higher MELD-Na scores, younger ages, non-O blood groups, and LT listings before 2017.

This paper aims to assess the influence of emotional intelligence on organizational commitment. A quantitative survey was conducted among the academic staff of Lebanese universities to reach this objective. This research paper is an explanatory, descriptive, and confirmatory study. This cross-sectional study is based on a quantitative method to examine the validity of the theory or model. This research favors the deductive approach. This approach enables the deduction of a general conclusion from hypotheses. The structured questionnaire is constructed on the theoretical constructs of the mixed approach of the Goleman model, evaluating the following six components: self-awareness, self-control, internal motivation, empathy, leadership skills, and interpersonal relationship management. Empirical testing incorporates the plurality of causes and effects of interaction in this explanatory, descriptive research. Universities confront a lack of employee commitment. Emotional appreciation drives commitment to the organization. E.I. denotes the aptitude to detect, categorize, and use feelings to smooth rational decisions. The study verified that E.I. components significantly and positively influence organizational commitment, with internal motivation having the highest influence in Lebanese universities. Soft skills are essential abilities. Decision-makers and managers of Lebanese universities, conscious and attentive to the influence of employees' emotions, should integrate emotional intelligence into their managerial practices. To build and maintain organizational commitment, displaying appropriate emotions, interpersonal relationships, and communication are compulsory.

Published: September 2024

This research paper delves into the various factors influencing the recovery of COVID-19 patients in Pakistan, with a specific emphasis on the impact of tobacco smoking. To unravel these connections, we conducted a data collection campaign employing a custom-designed questionnaire, gathering responses from 170 individuals who had successfully recovered from the coronavirus. Subsequently, we employed the Ordinary Least Squares (OLS) method to examine the influence of socio-economic factors on the recovery process. Our findings revealed that patients within the age range of 36 to 46 years exhibited an extended recovery period, requiring an additional three days for recuperation compared to their younger counterparts aged 17 to 25 years. Furthermore, patients aged above 46 years experienced a more prolonged recovery period, with a delay of up to seven days. Residence played a pivotal role in recovery times, as urban-dwelling patients showed a noteworthy advantage, recuperating 1.5 days sooner than their rural counterparts. A conspicuous relationship emerged regarding smoking habits, as patients who smoked tobacco required an additional two days for recovery when compared to non-smokers. Similarly, patients classified as obese experienced 2.6 more days to regain their health compared to individuals with a normal Body Mass Index (BMI). Remarkably, our analysis revealed that factors such as income, gender, and education were insignificant in terms of the number of the days required for recovery. These results provide a comprehensive understanding of the dynamics at play in the recovery process of COVID-19 patients in Pakistan, offering valuable insights for healthcare professionals and policymakers.

Authors: Tahar Tioua , Djamel Djeghader
Published: September 2024

The mechanical and physical properties of glass fiber composite materials can be modified when immersed in water. This change in properties can result from internal instability of the material, interaction with the environment, mechanical stresses, or a combination of these effects. In this study fiber glass reinforced polyester resin plates have been manufactured by the contact molding method with 20% of reinforcement percentage. Prismatic specimens have been cut then notched to evaluate the impact toughness by applying the Charpy impact test. The Williams method based on the principle of linear elastic fracture mechanics was used to deduce the impact toughness of composite. These specimens have been immersed in water for 30 and 90 days to study absorption effect and diffusion on the impact behavior of this material. From the results, it is found that there is a direct correlation between water penetration in the glass-polyester composite and its impact toughness.

This study investigated the wear resistance of AA1050 aluminum alloy coated using plasma deposition with a vanadium cathode cage and evaluated the effect of subsequently applying a plasma nitriding process to the coated sample. The treatments were carried out at 400°C for 3 hours. To evaluate the composition, thickness and wear resistance of the layers formed, X-ray fluorescence (XRF), scanning electron microscopy (SEM) and fixed ball micro-abrasive wear tests were applied. The treatments altered the wear mechanisms, with the treated samples also showing the two- and three-body wear modes, compared to the aluminium alloy, which only showed the two-body wear mode. The sample coated using only the cathodic cage deposition technique obtained a greater layer thickness (7.6 μm) and better wear resistance, with a reduction of around 83% in the worn volume compared to the 1050 aluminum alloy. However, the subsequent plasma nitriding process proved to be detrimental to the tribological properties of the coating formed, reducing the layer thickness (3.2 μm) and decreasing wear resistance.

Published: September 2024

Carbides and Nitrides of transition metals are widely used due to their interesting properties. Several deposition methods and techniques can be used to produce carbide and nitride coatings. The choice of how to make the deposit depends on several parameters such as, the conditions of use of these deposits, the thickness to be produced, the adhesion between the substrate the deposit, and the cost. In this work, hard coatings of chromium carbide were produced by a conversion treatment on 100Cr6 and X200Cr12 steels. The conversion treatment consists of electrode position of chromium on the surface of 100Cr6 and X200Cr12 steels followed by diffusion annealing treatment at 1000 and 1100 °C for holding times of 1 and 2 hours. The obtained results show that, for all the conversion treatments carried out in this work, there was formation of chromium carbides layer on the surface of steel. However, it should be noted that the nature of the constituting phases of the formed layer depends on the temperature of the diffusion annealing treatment and the duration at this temperature. It should also be noted that the X-ray diffraction analysis has allowed us to show the existence of chromium oxide in addition to chromium carbides. The microhardness profile and the scratch test show that the X200Cr12 steel sample shows better results.These properties are usually obtained by expensive methods such as PVD, CVD, while we can obtain them by easy and inexpensive methods.

Published: September 2024

In this study, two-dimensional unsteady laminar convective heat transfer from two isothermal cylinders arranged in tandem in horizontal duct has been numerically investigated. The numerical study is performed by solving the governing equations (continuity and momentum) and energy equations using a finite volume-based code ANSYS Fluent. The present study was conducted using nano sized copper particles suspended in water. The Prandtl number Pr of the resulting suspension being equal to 7. The range of solid volume fractions studied is and the flow Reynolds number is equal to 100.The spacing ratio of the two cylinders was varied from 2 to 5 while the blockage ratio was kept constant β=0.25. A detailed discussion has been provided regarding the variation of flow structure and the characteristics of flow, including total drag and lift coefficients, as a function of the dimensionless parametersIn order to visualize the flow and heat transport, streamlines, vorticity contours and isotherms were generated. In addition, the local and average Nusselt numbers for the upstream and downstream cylinders are calculated. The results demonstrate that the force coefficients, the wake structure behind the cylinders, and the Nusselt number are significantly influenced by the value of the spacing ratio and the volume fractions of nanoparticles. The results demonstrate a significant enhancement in heat transfer efficiency relative to the base fluid. The aforementioned improvement is more pronounced in the case of higher gap ratios and higher nanoparticle volume fractions.
The adaptive mean estimation of heavy tailed distribution under random censoring
Authors: Kouider Mohamed Ridha , Kheireddine Souraya , Benatia Fatah
Published: September 2024

We propose an alternative estimator of the heavy tailed mean under censored data relies with the threshold t which divides it into two parts for x ≤ t and x > t  respectively. In the first parts we present an empirical distribution function under random censoring (rc). Then, we check the convergence of Lyapunov condition to ensuring the asymptotic normality of this parts. For the second parts we use the Peaks-Over-Threshold (POT) method of the tail distribution and fitting to the generalized Pareto distribution (GPD). Intentionally to give an alternative estimator of the tail expected value for the heavy tailed distribution when x > t under random censoring relies the KIB estimators of the GPD parameters. Ditto, we ensuring the asymptotic normality property of the KIB estimators with bias reduced and we present the asymptotic normality of the second parts when x > t. An asymptotically normally distributed estimate for the heavy tailed mean estimation with infinite variance under censored data is introduced by combining the two parts. Finally, numerical examples are presented at the end of the paper to demonstrate the reliability of this estimation procedure and to better illustrate the results of this paper.

Introdução: A infecção criptocócica do trato gastrointestinal raramente é relatada, seja na doença disseminada ou como um achado isolado. Esse relato de caso representa um alerta para considerar o criptococoma como diagnóstico diferencial de abdome agudo. Relato do caso: Relatamos um caso de criptococose colônica isolada sem doença disseminada em uma mulher imunocompetente de 84 anos, sem infecção pelo HIV, que apresentou quadro de abdome agudo obstrutivo associado a febre, diarreia crônica e a perda de peso. Discussão: A criptococose é uma infecção fúngica raramente relatada em pacientes sem infecção pelo vírus da imunodeficiência humana (HIV), especialmente quando o sistema nervoso central (SNC) ou o sistema pulmonar não estão envolvidos.  O diagnóstico foi baseado no exame histopatológico após laparotomia exploradora e hemicolectomia a direita com ileostomia terminal. Além disso, realizamos uma revisão de literatura mostrando que poucos relatos de criptococose intestinal foram publicados até o momento. Conclusão: A infecção criptocócica colônica isolada é rara e seu prognóstico é favorável entre os pacientes não infectados pelo HIV, porém em paciente com múltiplas comorbidades deve ser considerado como diagnóstico diferencial de neoplasia no abdome agudo obstrutivo.

Taquicardia ventricular (TV) é uma arritmia causada por doenças cardíacas estruturais, seja de origem isquêmica ou não isquêmica, que está associada a um risco elevado de morte súbita. A principal causa de TV é um evento isquêmico anterior, que leva à formação de uma cicatriz irreversível no ventrículo, alterando substancialmente a função elétrica do miocárdio ventricular e remodelando suas vias de condução. Dependendo das condições clínicas do paciente, diferentes abordagens terapêuticas podem ser adotadas para tratar TVs. Entre as diversas opções de tratamento disponíveis, a ablação por cateter é considerada uma estratégia eficaz para o manejo de diferentes formas de TV, especialmente aquelas associadas a cicatrizes. No entanto, é comum que mais de um procedimento seja necessário para alcançar o sucesso completo do tratamento. Dessa forma realizou-se uma revisão sistemática de literatura por meio da plataforma pubmed, com seleção e análise criteriosa dos artigos, a fim de elucidar os aspectos da ablação robótica no contexto da taquicardia. Nesta revisão, foi identificado pontos positivos, onde o uso de navegação magnética robótica (RMN) para ablação é eficaz e segura para diversas arritmias, oferecendo controle preciso e reduzindo a exposição à radiação. Adiante, sistemas de mapeamento avançados permitem reconstruções 3D da anatomia cardíaca, reduzindo a necessidade de fluoroscopia e otimizando a identificação de substratos, aumentando a precisão das intervenções. Em contrapartida, a escolha da técnica de mapeamento e ablação depende da complexidade anatômica, estabilidade hemodinâmica, e características individuais da TV, assim, sendo um desafio nas considerações clínicas

Optimizing Sleep/Wake Related Cognitive Efficacy in Laborist Paradigms
Authors: Dow Margaret
Published: September 2024

Workload and schedule optimization has been the subject of numerous studies in surgery, emergency medicine, and resident education literature.No studies have been done to evaluate the role of fatigue and cognitive efficacy in the neophyte laborist specialty, though increasing patient safety is an underlying assumption of this model of care. Using a validated actigraphy based wristband, ReadiBand, and its proprietary analysis algorithm, SAFTE (sleep, activity, fatigue, and task effectiveness), we attempted to quantify cognitive efficacy of laborists during three types of shifts, patterns of efficacy through different rotations of the schedule, and the impact consecutive night shifts on fatigue.After a targeted fatigue avoidance education session, data were collected again. Patterns of improved efficacy and sleep efficiency emerged, which may have implications for designing ideal laborist scheduling and workflow.
Research on the Mechanism of Occupational Burnout among Rural Primary School Teachers
Authors: Zeng Jiao
Published: September 2024

Occupational burnout is a phenomenon that occurs in the career of primary school teachers, which is very detrimental to their own development and student growth. Through a qualitative study of 15 teachers at L Elementary School, it was found that individual environments are formed by physical condition, age, university background, family situation, work experience, personality traits, and ideal pursuits. Family school cooperation, leadership style, student situation, and teaching reform shape the collective environment. Time allocation, energy allocation, and ability allocation form a sense of professional rhythm, and being trusted, recognized, valuable, and growing form a sense of professional achievement. Among them, the sense of occupational rhythm and occupational achievement directly affect the occupational burnout of rural primary school teachers, while individual and collective environments indirectly affect occupational burnout through the sense of occupational rhythm and occupational achievement. Rural primary school teachers should be guided to rationally view professional burnout, attach importance to career guidance for rural primary school teachers, and further optimize the professional environment for rural primary school teachers.

FREQUENCY OF LOSS OF MISMATCH REPAIR PROTEINS’ IMMUNOHISTOCHEMICAL EXPRESSION IN SEBACEOUS NEOPLASMS, POTENTIAL MARKERS/TOOLS INDICATING THE POSSIBILITY OF MUIR-TORRE SYNDROME
Authors: QURESHI R , FATIMA S
Published: September 2024

Screening for Muir-Torre Syndrome (MTS) using Mismatch Repair (MMR) gene immunohistochemistry (IHC) on sebaceous neoplasms (SNs) is technically feasible. Research for this indication is limited, especially in Asia. To address this knowledge gap, we examined the frequency of loss of IHC staining of MMR proteins in SNs. Methods: We conducted a cross-sectional study including 98 patients (120 SNs). Eleven out of 98 patients had concurrent or subsequent SNs. Results: The size and type of tumor showed a significant association with MMR loss. Fifteen (12.5%) sebaceous adenomas, 12 (10.0%) sebaceous, and 93 (77.5%) sebaceous carcinomas were included in the study—sixty-one (50.83 %) SNs presented with loss of one or more MMR proteins. Isolated loss of MSH2 was the most common IHC pattern (27.8%). Fifty cases (29.58%) showed a combined loss of MSH2 and MSH6, and 40 (23.66%) showed a combined loss of MLH1 and PMS2. Most SAs showed isolated loss of MLH1 and PMS2 (7, 26.9% each). Sebaceomas showed isolated loss of MSH2 and MSH6 as the most common (4, 33.3%) pattern. Isolated loss of MSH2 only (37, 28.2%) was the predominant pattern of IHC loss in SCs. Weak to fragile associations between MMR protein status and histopathological findings were observed, with the most notable association being between MLH1 and ulceration on the surface. The models have an accuracy of around 50%, indicating moderate prediction capability. In our cohort, personal and family history was available in 33 cases (25 out of 98 patients). Conclusion: We recommend that MMR IHC be performed routinely on all SNs, considering clinicopathological factors of the lesions, mainly the anatomic site and tumor type. The panel should include antibodies against all four MMR proteins.

Authors: SHAHEEN T , ZIA N , MUI LG , NORDIN R
Published: September 2024

Maternal anxiety during labor can adversely affect both the mother and fetus. Effective management strategies, including non-pharmacological interventions like breathing patterns, are crucial to improving labor outcomes and maternal well-being. Objective: To evaluate the efficacy of breathing patterns for the management of maternal anxiety during the dilation phase of labor. Methods: A prospective study was conducted in the Physiotherapy and Obstetrics and Gynecology Department of DHQ Hospital from April 2023 to April 2024. One hundred fifty pregnant women in active labor with gestational ages of 37-41 weeks were included. The patients were divided into the study group (70 women) and the control group (80 women). The control group followed standard labor procedures, while the study group was guided on breathing patterns according to a specified protocol. The primary endpoint was maternal anxiety, and secondary endpoints included pain, fatigue, satisfaction, labor duration, and delivery mode. The 5-minute Apgar score was also assessed for the fetus. Statistical analysis was performed to compare outcomes between the groups. Results: Baseline maternal outcomes, including pain, fatigue, anxiety, satisfaction, and labor duration, showed no significant differences between the study and control groups. The mean labor duration was 7.70 ± 3.36 hours for the study group and 8.00 ± 2.54 hours for the control group, with a mean difference of 0.30 hours (95% CI 1.35-0.78). Maternal outcomes did not differ between groups after two hours of protocol implementation and sensitivity analysis. The delivery mode was similar in both groups, with a relative risk of 0.10 (95% CI 0.78-1.09) and 0.10 (95% CI 0.77-1.10) for protocol and sensitivity analysis, respectively. The 5-minute Apgar scores also showed no significant differences between the groups. Conclusion: Using breathing patterns during active labor did not significantly impact maternal outcomes, including pain, satisfaction, anxiety, and fatigue.

Email types sorting is one of the most important tasks in current information systems with the purpose to improve the security of messages, allowing for their sorting into different types. This paper aims at studying the Convolution Neural Network and Long Short-Term Memory (CNN-LSTM), Convolution Neural Network and Gated Recurrent Unit (CNN-GRU) and Long Short-Term Memory (LSTM) deep learning models for the classification of emails into categories such as “Normal”, “Fraudulent”, “Harassment” and “Suspicious”. The architecture of each model is discussed and the results of the models’ performance by testing on labelled emails are presented. Evaluation outcomes show substantial gains in precision and throughput to conventional approaches hence inferring to the efficiency of these proposed models for automated email filtration and content evaluation.

Published: September 2024

Pediatric dentistry is a unique, dynamic specialty that manages young children and shapes their healthy and beautiful smiles. A pediatric dentist plays a major role in introducing dentistry to a child for the first time. His/her responsibilities include understanding the child's genetics and environment, modifying oral habits and behavior, and successfully instilling healthy oral hygiene practices. It is an ever-so-gratifying experience to witness them reach these milestones and develop positive dental attitudes. Therefore, training is essential for every pediatric dentist to deliver optimal dental care to infants, children, and teenagers. As a responsible practitioner, a pediatric dentist must absorb all the latest innovations, evaluate them, and appraise them in order to bring more smiles and build a healthier generation. Therefore, this research paper briefly explores the future and challenges of pediatric dentistry.

Aim: To assess child personality attributes using Pictorial Personality Traits Questionnaire Children (PPTQ-C) for prediction of child behavior at the first dental visit and its co-relation with the Frankl behavior rating scale. Methodology: A sample size of 110 children between the ages 6-9 years requiring preventive treatment was included and they were asked to fill out the PPTQ-C before the treatment. The personality trait was evaluated. The Frankl behavior rating of the subjects was noted at the time of the treatment. A correlation was established between the personality trait and Frankl behavior rating scale. The Pearson correlation test was used to obtain a correlation between the Frankl behavior rating scale and the personality traits. Results: A positive correlation was found between the trait of Extraversion and a negative correlation between Neuroticism and the Frankl behavior rating scale. Conclusion: The PPTQ-C can be used to assess child personality attributes for the prediction of child behavior at the first dental visit. However, the findings are preliminary and need to be validated with bigger sample sizes across varied groups.
Deep Learning Concept for Early Dental Caries Detection
Authors: Kotha Dr Sunil Babu
Published: September 2024

Identifying dental caries in a dental operatory can be challenging for pediatric dentists at times because of the fluctuating features of the lesions based on their developmental stage. Thus, pediatric dentists can suggest specific and unique treatment methods. Noninvasive interventions, such as fluoride therapy and sugar control, can successfully reverse and treat early aberrations, sometimes referred to as white spots. Dental cavities, on the other hand, lead to tooth structure deterioration and require restorative treatments of varying levels of difficulty, depending on the extent and severity of the damage that leads to the extraction of the tooth itself. These necessitate new concepts for detecting dental caries in children. The prospective review's objective was to determine the necessity of applying deep learning and contemporary principles in the diagnosis of early childhood caries.
