Authors: Karim Akbal Nur , Santosa Agung
Published: December 2023

The issue of decreased visual acuity in children, especially in primary and junior high school ages, has not been well socialized. Many children and parents still lack understanding regarding the risk factors associated with daily activities that contribute to decreased visual acuity. This study is an analytical observational research using a cross-sectional approach. The research was conducted on all students from grade I to grade VI of SD Unggulan Al-Amin, totaling 266 individuals, and all students from grade VII to grade IX of SMP Unggulan Al-Amin, totaling 120 individuals. Data were collected through visual acuity examinations using the Snellen chart at 6 meters and interviews guided by a questionnaire. Data were analyzed using the chi-square test. Among the students of SD Unggulan Al-Amin, six factors were found to have a significant relationship with decreased visual acuity based on the chi-square test. These six factors are reading position (p=0.001), frequency of cellphone use (p=0.000), duration of gadget use (p=0.001), gadget usage position (p=0.040), distance while watching TV (p=0.046), and distance from eyes to cellphone screen (p=0.019). Among the students of SMP Unggulan Al-Amin, eight factors were found to have a significant relationship, including reading position (p=0.00), frequency of cellphone use (p=0.000), duration of gadget use (p=0.000), gadget usage position (p=0.000), frequency of TV watching (p=0.001), duration of TV watching (p=0.000), distance while watching TV (p=0.000), and distance from eyes to cellphone screen (p=0.000). Decreased visual acuity was experienced by 56.8% of students from SD Unggulan Al-Amin and 18.3% of students from SMP Unggulan Al-Amin. There is a significant relationship between risk factors and decreased visual acuity, including reading position, frequency of cellphone use, duration of gadget use, gadget usage position, frequency of TV watching, duration of TV watching, distance while watching TV, and distance from eyes to cellphone screen.

Published: December 2023

Sınava giren öğrencilerin başarılarını etkileyen durumlardan biri sınav kaygısıdır. Bu sorunu ortadan kaldırmak amacıyla birçok çalışma yapılmış; özellikle de son dönemlerde teknolojinin etkisi araştırılmıştır. Ancak net bir sonuca ulaşılamamıştır. Bu nedenle araştırmada, teknoloji içerikli Kahoot ve klasik sınav yöntemlerinin, sınav kaygısı üzerinde herhangi bir farklılık oluşturup oluşturmadığını ortaya koymak amaçlanmıştır.
Çalışma karşılaştırmalı, deneysel bir çalışma olup ön-son test yöntemi uygulanmıştır. Araştırmanın örneklemini, Fenerbahçe Üniversitesi Sağlık Bilimleri Fakültesi’nde ortak ders alan 1. sınıfta eğitim gören 78 öğrenci oluşturmuştur. Yaş ortalamaları 20,12 ± 1.62 olan 18-31 yaş arasındaki öğrenciler rastgele sayılar tablosu kullanılarak iki gruba (Kahoot Grubu - KG; n: 38 / Klasik Sınav Grubu - KSG; n: 40) ayrılmıştır. Her iki gruba da 20 sorudan oluşan 30 dakikalık bir sınav uygulanmıştır. Sınav öncesi verilerin elde edilmesinde öğrenci bilgi formu ve sınav kaygısı ölçeği kullanılmıştır. Ön-son test yönteminin kullanıldığı çalışmada, sınav sonrası ölçekler yinelenmiştir ve sınavın öğrenciler üzerinde yarattığı kaygı düzeyleri belirlenmiştir. Araştırmanın sonuçlarına göre, her iki grup arasında da hem akademik başarı hem de sınav kaygısı açısından anlamlı bir farklılık bulunmamıştır. İki grup arasında bir farklılık olmamasına karşın; kullanımı kolay, eğlenceli ve motive edici özelliğinden dolayı Kahoot uygulaması öğrencilerin eğitim ve değerlendirme sürecinde önerilebilir. Ayrıca sınav sonuçlarının kısa sürede raporlanmasının akademisyenler için önemli bir avantaj sağlayacağına inanıyoruz.

Published: December 2023

The most common markers used in the diagnosis of the colon cancer are CEA and CA 19-9. Chemotherapy is applied as an adjuvant and a neo-adjuvant treatment in colon cancer.

Our aim was to investigate the effects of FOLFOX and CAPOX on CEA and CA 19-9 levels before and after chemotherapy in different patient groups.

The CEA and CA 19-9 values before and after chemotherapy for the 60 patients diagnosed with metastatic colon cancer having FOLFOX or CAPOX therapy age over 18 whom hospitalised between 2017-2020, were used.

The mean value for CA 19-9 of T0 for FOLFOX receiving group was calculated as 263.71 ± 709.87 U/ml and was 119.57 ± 246.34 U/ml of for the 3rd month. The mean value for CEA for receiving FOLFOX was calculated as 76.11 ± 204.22 ng/g at T0, and 50.53 ± 142.50 ng/g at the 3rd month. The mean value of CEA for receiving CAPOX was calculated as 139.62 ± 388.87 ng/g at T0, and 117.05 ± 272.08 ng/g at the 3rd month. Intertemporal CEA levels of individuals receiving CAPOX were found to show significant differences (p=0.074). CA 19-9 mean of T0 was calculated as 218.43 ± 605.53 U/ml and the 3rd month mean of 174.40 ± 465.61 U/ml of the patients receiving CAPOX. It was found that the intertemporal values of the individuals in terms of CA 19-9 levels were not statistically significant (p=0.649).

In conclusion, CA 19-9 and CEA levels of the patients decreased even more in the 3rd month when treated with FOLFOX. The decrease in CEA was found to be more significant. In terms of CAPOX treatment, the interquartile range T0 and the 3rd month levels did not show a significant difference, statistically (p=0.143 and p=0.089).

Published: December 2023

Numerous disasters occur due to the inability to manage risks arising from natural, technological, and human-induced hazards. As a result of these disasters, the magnification of incurred damages underscores the significance of the concept of risk management, an integral step in disaster management. Consequently, efforts to mitigate the adverse effects of earthquakes and other disasters are progressively increasing. However, endeavors aimed at reducing the damages inflicted by earthquakes and other disasters on structures, particularly earthquakes, are not yet at an adequate level. Presently, the importance of alternative solution models to counteract the forces exerted on structures during disasters like earthquakes is on the rise.In this study, unreinforced concrete blocks were coated with flexible polyurea, a state-of-the-art cladding material extensively used in various fields, at different thicknesses. Three-point bending tests were performed on the coated specimens. The data obtained from these tests were analyzed and evaluated. It was concluded that specimens coated with polyurea exhibited higher strengths compared to uncoated specimens. This study introduces the utilization of polyurea flexible composite material in structural elements as an alternative method within the spectrum of precautions taken to enhance the safety of structures against various disasters, primarily earthquakes.

The research was done descriptively and cross-sectionally to define the relationship between women's health literacy and their anxiety levels regarding breast cancer. 315 female patients participated in the study who are over the age of 20 and inpatient women of a training and research hospital. The interval of study was three months (May and July 2022). Researchers obtained the research data with face-to-face interview technique and they used the "Personal Information Form", "Breast Cancer Concern Scale (BCCS)", and "Health Literacy Scale (HLS)". The mean HLS and BCSS scores of women were 103.8±19 and 9.2±5.6 respectively. It has been found that women's employment status, menopause, education level and knowledge of breast self-examination (BSE) and having BSE have an impact on their level of health literacy. With correlation analysis, it was defined that there was a statistically insignificant and low level, negative relationship between the women’s total mean scores of HLS and the BCCS (r=-0.06, p>0.05). As a result, it was determined that women had above moderate level of health literacy and low level of anxiety about breast cancer, and there was no relationship between health literacy level and breast cancer anxiety. The results showed that women's education level, working outside the home, menopause status, and whether they know and regularly practice BSE affect their health literacy.

Authors: ŞAHİN Ali , GÜL Mehmet
Published: December 2023

Social media has become an indispensable part of the daily lives of most people who have come into contact with technology, and is one of the basic sources of communication and free expression. The popularity and number of social media users, which shape people’s behavior and enable online socialization, is increasing day by day. This increase can be largely attributed to the increasing number of computers, tablets, and especially smartphones, as well as the decreasing age of users. From this point of view, the aim of this study is to determine the motives of fans of the teams of the Turkish Football Super League for using social media. In this framework, a total of 460 people who were selected from the population according to the principle of random sampling constitute the sample of the study. In the study, the “Personal Information Form” prepared by the researcher was used to determine the demographic characteristics of the participants, and the “Motivations of Fans to Follow Their Teams on Social Media Scale” was used to investigate the fans’ motives for using social media. The descriptive statistics of the variables were conducted in the form of percentages (%), frequency, mean, and standard deviation using SPSS 25 package program for the analysis of the research. On the other hand, the t-test for independent samples and analysis of variance, which are parametric tests, were used to test the relationships between the variables. The result is that in the study of the motivations of fans to follow the accounts of the teams they support in social media, the gathering of information, sharing of information and the perception of being a fan are the most important. Therefore, it is recommended that clubs get to know their fan base and enrich the content of strongly preferred social media accounts according to the identified motivations to ensure the active participation of fans in this process.

Published: December 2023

Mental imagery is an essential element in the human movement system. Research in the sports psychology literature shows that training with motor imagery (mental practice) is an effective strategy for improving motor performance in planning and executing goal-directed movements. The primary objective of this study is to explore the impacts of integrating mental and physical training on the acquisition of a demanding football motor skill, specifically the "head kick." A total of 40 participants, consisting of 18 women and 22 men, who were students from the Physical Education & Sports department at Nevşehir Hacı Bektaş Veli University, were randomly divided into two groups: one group receiving combined physical education and mental practice, and the other group solely undergoing physical education training. The Vividness of Movement Imagery Questionnaire–2 (VMIQ-2; Roberts et al., 2008) and video analysis procedure were used in this study. Based on the research problem, the Repeated Measure ANOVA test was used. Motor skill performance was assessed both before and after an eight-week training period. To gauge improvements in motor skill acquisition, three independent expert evaluators analyzed video recordings of the motor task before and after training in both situations. The findings highlighted that engaging in mental imagery exercises improved timing and coordination, emphasizing the potential effectiveness of this intervention for enhancing proficiency in intricate motor skills. These study findings also illustrate the practicality and precision of employing video-based motion analysis to gauge enhancements in motor performance.

Published: December 2023

Prawn pre-processing, locally called prawn peeling is a labour-intensive activity. More than 90 per cent of the workforce in prawn pre-processing centres are women 1. Occupational health problems among prawn-peeling workers are a matter of serious concern. The workers lack awareness and knowledge of occupational health hazards and safety. In the peeling sheds, they are exposed to cold environments, chlorinated water, and fish protein-related bio-agents.
In most of the peeling sheds, women work in a sitting or squatting position, bending forward while peeling. The floor of the peeling sheds is waterlogged, and the women must spend long hours on the wet floor which is the root cause of many of their ailments. Joint pain, low back pain, numbness of hands and legs, and various forms of allergies are health problems attributed to the work environment and work posture.

Early Postoperative Change in Hip Rotation Angle and Factors Contributing to It for Patients Undergoing Total Hip Arthroplasty
Authors: Tateiwa Toshiyuki , Masaoka Toshinori , Takahashi Yasuhito , Ishida Tsunehito , Shishido Takaaki , Yamamoto Kengo
Published: December 2023

Objective:

A possible impairment in hip proprioception after total hip arthroplasty (THA) has been an issue of concern. The aims of this study were to investigate the extent of early postoperative change in standing hip rotation angle (HRAng) in patients with osteoarthritis (OA) undergoing THA and to consider a possible mechanism behind this.

Materials and Methods:

A total of 82 hips (82 patients; 63 women and 19 men) undergoing unilateral primary THA with total capsulectomy were included. We characterized the standing HRAng and internal/external range of motion (ROM) in the prone position before THA and 2 weeks after THA. Acetabular/cup and femoral/stem anteversion, combined anteversion (CA), and leg length discrepancy were also characterized. Correlations were examined postoperatively between the HRAng and the other analyzed variables.

Results:

The median standing HRAng showed a significant internal shift from external to more medial position (6.3° to 1.7°) 2 weeks after THA (
P
<.0001). The postoperative change in standing HRAng was significantly negatively correlated with the difference between the postoperative femoral anteversion and the stem anteversion (
r
s
=−0.429,
P
<.0001) and with the pre- to postoperative change in CA (
r
s
=−0.3012,
P
=.0063).

Conclusion:

This study demonstrated that the extent of the rotational shift of the distal femur toward medial direction was significantly associated with increasing stem anteversion and CA. This phenomenon can be interpreted as a compensatory mechanism for maintaining the relative positional relationship between the pelvis and the proximal femur using proprioception. Therefore, we conclude that the extracapsular/extra-articular components may be prominent determinants of joint position sense. [

An implicit fully discrete compact finite difference scheme for time fractional diffusion-wave equation
Authors: An Wenjing , Zhang Xingdong
Published: December 2023

In this paper, an implicit compact finite difference (CFD) scheme was constructed to get the numerical solution for time fractional diffusion-wave equation (TFDWE), in which the time fractional derivative was denoted by Caputo-Fabrizio (C-F) sense. We proved that the full discrete scheme is unconditionally stable. We also proved that the rate of convergence in time is near to $ O(\tau^{2}) $ and the rate of convergence in space is near to $ O(h^{4}) $. Test problem was considered for regular domain with uniform points to validate the efficiency and accuracy of the method. The numerical results can support the theoretical claims.
Commuting Toeplitz operators and H-Toeplitz operators on Bergman space
Authors: Ding Qian
Published: December 2023

In this paper, we consider the H-Toeplitz and Toeplitz operators acting on the Bergman space. First, we describe the characterizations of commutativity of two H-Toeplitz operators with certain harmonic symbols. For the general case, it seems very hard. As an extension to the study of Toeplitz operators on the Bergman space, we present the necessary and sufficient conditions of the commutativity of the H-Toeplitz operator and the Toeplitz operator with non-harmonic symbols.
Twisted Rota-Baxter operators on Hom-Lie algebras
Authors: Xu Senrong , Wang Wei , Zhao Jia
Published: December 2023

Uchino initiated the investigation of twisted Rota-Baxter operators on associative algebras. Relevant studies have been extensive in recent times. In this paper, we introduce the notion of a twisted Rota-Baxter operator on a Hom-Lie algebra. By utilizing higher derived brackets, we establish an explicit $ L_{\infty} $-algebra whose Maurer-Cartan elements are precisely twisted Rota-Baxter operators on Hom-Lie algebra s. Additionally, we employ Getzler's technique of twisting $ L_\infty $-algebras to establish the cohomology of twisted Rota-Baxter operators. We demonstrate that this cohomology can be regarded as the Chevalley-Eilenberg cohomology of a specific Hom-Lie algebra with coefficients in an appropriate representation. Finally, we study the linear and formal deformations of twisted Rota-Baxter operators by using the cohomology defined above. We also show that the rigidity of a twisted Rota-Baxter operator can be derived from Nijenhuis elements associated with a Hom-Lie algebra.
A global progressive image secret sharing scheme under multi-group joint management
Authors: Zhang Lina , Zhang Jing , Sun Jiaqi , Chen Qingpeng
Published: December 2023

Diverging from traditional secret sharing schemes, group secret sharing schemes enable the recovery of secret information through collaborative efforts among groups. Existing schemes seldom consider the issue of the secrecy level of image information between different groups. Therefore, we propose a global progressive image secret sharing scheme under multi-group joint management. For inter-group relations, multiple groups with different priority levels are constructed using the approach of bit-polar decomposition. In this arrangement, higher-level groups obtain clearer secret image information. For intra-group relations, a participant-weighted secret sharing scheme is constructed based on Chinese Remainder Theorem and Birkhoff interpolation, in which the participants' secret sub-shares are reusable. During the recovery process, the sub-images can be recovered within the intragroup with the corresponding level. Groups collaborate through lightweight overlay operations to obtain different layers of secret images, achieving a global progressive effect. Analysis results show that the scheme is both secure and practical for group secret sharing.
PAIGE: A generative AI-based framework for promoting assignment integrity in higher education
Authors: Shanto Shakib Sadat , Ahmed Zishan , Jony Akinul Islam
Published: December 2023

The integration of Generative Artificial Intelligence (GAI) tools like ChatGPT, Google Bard, and Bing Chat in higher education shows excellent potential for transformation. However, this integration also raises issues in maintaining academic integrity and preventing plagiarism. In this study, we investigate and analyze practical approaches for efficiently harnessing the potential of GAI while simultaneously ensuring the preservation of assignment integrity. Despite the potential to expedite the learning process and improve accessibility, concerns regarding academic misconduct highlight the necessity for the implementation of novel GAI frameworks for higher education. To effectively tackle these challenges, we propose a conceptual framework, PAIGE (Promoting Assignment Integrity using Generative AI in Education). This framework emphasizes the ethical integration of GAI, promotes active student interaction, and cultivates opportunities for peer learning experiences. Higher education institutions can effectively utilize the PAIGE framework to leverage the promise of GAI while ensuring the preservation of assignment integrity. This approach paves the way for a responsible and thriving future in Generative AI-driven education.
Ecología reproductiva de Cipadessa baccifera (Meliaceae)

Published: December 2023

Cipadessa baccifera es un arbusto leñoso que se propaga a través de semillas y raíces subterráneas. Las flores muestran androceo urceolado, protandria fuerte y receptividad del estigma mostrada por la cabeza del estilo turbinada que permite un mecanismo de polinización secundaria. Son autocompatibles, nectaríferas y producen los tres azúcares comunes y ciertos aminoácidos en el néctar, y también ciertos aminoácidos en el polen. Además, las flores presentan un síndrome de polinización generalista adaptado a la polinización por diferentes clases de insectos. Las abejas, avispas y mariposas actúan como polinizadores; el primer grupo efectúa principalmente geitonogamia, mientras que los otros dos, principalmente xenogamia. En esta especie, la autogamia espontánea no es funcional porque la protandria la impide. Sin embargo, los visitantes de las flores podrían efectuar la autogamia después de que el estigma alcance la receptividad, pero en ese momento los insectos han dispersado la mayor parte del polen de la flor. Las pruebas de polinización manual indicaron que la autogamia, la geitonogamia y la xenogamia manipuladas son funcionales con la mayor producción de frutos en el último modo. Tal sistema de reproducción indica la función de xenogamia facultativa que retrasa la autopolinización por protandria fuerte y promueve la polinización cruzada. El fruto es una drupa globular carnosa que produce de 5 a 10 semillas unidas por un arillo carnoso común. Los modos de dispersión de semillas son por ornitocoria, barocoria e hidrocoria. Por lo tanto, el modo dual de propagación, la xenogamia facultativa, el mecanismo de polinización secundaria, el síndrome de polinización generalista, la entomofilia y la policoria funcional de permite a C. baccifera crecer prolíficamente y ampliar su distribución en áreas donde no hay cobertura arbórea.

Published: December 2023

This work aimed to search for alternative uses for different varieties of Andean potatoes (Solanum tuberosum ssp andigenum) which have been reintroduced in north-western Argentina. Specifically, the development of simple and compound films made with hydrocolloids such as carboxymethyl-cellulose (CMC) and starch (S) extracted from Andean potatoes var. Runa, and its application as a cover in the deep frying of Andean potato chips var. Waycha was studied to minimize oil absorption. The effect of prior bleaching of the chips with different media was also evaluated: water, calcium chloride solution, and ascorbic acid. The coatings were applied to potatoes chips before being fried. The results showed that the type of oil used did not affect absorption by the chips. The bleaching treatments with calcium chloride and coating with S/CMC, showed a significant reduction in oil absorption (39.5 % ± 0.7), delayed its oxidation, and decreased the loss of tocopherols during the frying process. It also contributed to the physical and sensory characteristics of the final product, which presented high acceptability by consumers.

Authors: Ramezani P. , Rafati A. , Toorani M.R. , Golmakani M.T.
Published: December 2023

The antioxidant activity of curcumin (0.02-0.1%) was evaluated in olive, sesame, and safflower oils at 373, 383, and 393 K. The results were examined in contrast to the effects of tocopherol (0.1%) and BHT (0.02%), so that the inhibitory function of curcumin was evaluated comparatively. The activation energy of oxidation was determined for olive (82.94 kJ·mol-1), sesame (77.39 kJ·mol-1) and safflower oils (74.42 kJ·mol-1). Adding curcumin (0.1%) enhanced the activation energy by 26.26, 26.64, and 38.81% in the case of olive, safflower, and sesame oils, respectively. Based on Gibbs free energy, curcumin functioned more effectively in olive oil at 373 K (growth coefficient: 1.52%), compared to the action of the other two antioxidants, namely tocopherol (1.43%) and BHT (1.39%). The efficiency of curcumin was lower in oils which had a higher degree of polyunsaturation due to the disproportionation of the hydrogen-donating mechanism and the rate of free-radical formation in these oils.

Authors: Dey Piyali , Mandal Santa , Goyary Danswrang , Verma Anurag
Published: December 2023

Background & objectives:

Vector control measures are important in lowering the spread of infections spread by mosquito. Synthetic pesticides used to suppress vector populations during the larval stage have had adverse impacts on people and the environment. The early III instar larvae of Aedes aegypti and Anopheles stephensi were the targets of the current experiment, which assessed the larvicidal ability of petroleum ether, chloroform, methanol, and aqueous extracts of Annona squamosa leaves.

Methods:

Using the standard World Health Organization (WHO) larval bioassay test, leaf extracts were evaluated for their activity against Ae. aegypti and An. stephensi to determine lethal doses. Phytochemical analysis and gas chromatography-mass spectrometry (GC-MS) were carried out to identify larvicidal components in the extract. Further analysis using a scanning electron microscope (SEM) was done to check the extracts toxicity for both mosquito larvae.

Results:

The larvicidal active components were identified by GC-MS as tetradecanoic acid, cis-vaccenic acid, and 2,4-di-tert-butylphenol etc. Methanol leaf extracts of A. squamosa (ASME) exhibited strong larvicidal activity against the early 3rd instar larvae of Ae. aegypti and An. stephensi with Lethal concentration (LC50) values of 51.450 ppm and 107.121 ppm. Cell damages to the larva post exposure to ASME were examined.

Interpretation & conclusion:

This finding showed that the ASME has better larvicidal activity and its components that may be used to kill larvae as larvicides. The extracts toxicity towards damage of midgut of larva further suggests that this plant methanol leaf extracts could be effective in larval growth control approaches.

Authors: Wang Min-Hong , Hsiao Hui-Hua
Published: December 2023

We reported a rare case and experience of successfully treating primary anaplastic large-cell lymphoma (ALCL) of the breast with no history of breast implants, using a combination of novel brentuximab vedotin and chemotherapy. A 78-year-old woman presented with a painless lump over the left breast. The computed tomography scan revealed a 2.6-cm tumor in the left upper quadrant of the breast, along with enlarged lymph nodes in the left axilla, exhibiting similar imaging features to breast carcinoma. The definitive diagnosis was based on histopathology and immunohistochemistry stains consistent with ALCL. The patient received brentuximab vedotin in combination with cyclophosphamide, doxorubicin, and prednisone (CHP) chemotherapy, as well as involved site radiation therapy (ISRT). The following image showed almost complete remission.
Risk Predictors for Mortality in Inpatients with Cancer and Coronavirus Disease 2019 during the Omicron Wave
Authors: Chen Kuan-Yu , Lai Chih-Cheng , Huang Chien-Tai , Feng Yin-Hsun
Published: December 2023

Background:

Patients with cancer are a high-risk population in the coronavirus disease 2019 (COVID-19) pandemic. We analyzed the characteristics and risk factors for mortality in hospitalized patients with cancer and laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the Omicron wave.

Materials and Methods:

We conducted a retrospective, single-center, cohort study of 206 patients with cancer and SARS-CoV-2 infection in southern Taiwan. Clinical characteristics, laboratory data, and cancer characteristics were compared between survivors and nonsurvivors. Risk factors for mortality were identified by univariable and multivariable logistic regression models.

Results:

The median patient age was 69.5 years. Male preponderance was noted (65%). Comorbidities were present in 186 (90%) cases. A total of 113 (54%) patients had active cancer. Metastatic disease accounted for 78 (38%) cases, of whom 19 (9%) had lung metastasis. Sixty-four (31%) patients had active and progressing cancer status. The overall inhospital mortality rate was 17.4%. Univariate logistic regression revealed the following factors to be significantly associated with a higher risk of inhospital mortality among the patients with cancer and COVID-19: nosocomial COVID-19 infection (P = 0.037), lung metastasis (P = 0.005), received anticancer therapy in the preceding 3 months (P = 0.083), active and progressing cancer (P = 0.008), and quick Sequential Organ Function Assessment (qSOFA) score ≥2 (P < 0.001). However, only nosocomial infection (P = 0.021) and qSOFA score ≥2 (P < 0.001) were independent predictors of inhospital mortality in the multivariate logistic regression analysis.

Conclusion:

Cancer patients are a population vulnerable to the Omicron variant with higher mortality rate, especially those with nosocomial COVID-19 infection and those with a qSOFA score of ≥2 immediately after confirmation of COVID-19 infection. Thus, the rapid recognition of high-risk groups and nosocomial infection control are critical to prevent COVID-19 in patients with cancer.

Authors: Shadid Asem M. , Albdaya Norah A. , Aldosari Mosfer S. , Habib Mohammed , Aldera Reema M. , Almohaimeed Danah H. , Altalhab Saad
Published: December 2023

Background:

The shortfall of dermatology curricula during medical school greatly impacts the knowledge about common skin diseases and clinical skills. The lack of exposure to dermatology hampers the decision for students to consider pursuing dermatology and their preparation for matching.

Purpose:

The aims of this study were to assess the current state of dermatology curricula in medical school and to determine the relation of those factors to the selection of dermatology as a career.

Methods:

A nationwide cross-sectional study was conducted between September 2020 and May 2021 using a previously published questionnaire distributed to 25 universities across all regions of the Kingdom of Saudi Arabia.

Results:

Out of 1411 participants, around half reported having only 1–4 h of basic and clinical dermatology lectures. Forty-four percent were required to rotate in dermatology. Half of the respondents were expected to treat acne, sexually transmitted diseases, herpes, and candidiasis after finishing the dermatology course. Students in clinical years (odds ratio [OR] = 0.6 and confidence interval [CI] = 0.39–0.92) and interns (OR = 0.54 and CI = 0.30–0.94) were more likely to consider dermatology as their future career. Having a dermatology program in their university tended to generate interest in dermatology as a career choice (OR = 2.24 and CI = 1.55–3.24). Compared to students who did not complete a core dermatology course, students who completed core dermatology courses were twice as likely to be interested in dermatology as a future career (OR = 1.91 and CI = 1.35–2.70).

Conclusion:

Including core dermatology topics in the medical curriculum can help address community health needs and give students needed clinical experience and a basis for considering dermatology as a career path.

Authors: Verma Kritin K. , Dasuri Venkata S. , Friedmann Daniel P.
Published: December 2023

Background:

Although melasma is a common acquired facial dyschromia, its epidemiology in the general population has not been clearly elucidated.

Purpose:

To investigate the prevalence of melasma and its correlation with demographic factors, such as age and race, using the All of Us open-access database initiative from the National Institutes of Health in the United States.

Methods:

A cross-sectional statistical analysis of patients with a diagnosis of melasma in the All of Us open-access database initiative from the National Institutes of Health was performed.

Results:

A total of 744 reported cases of melasma were found in a population of 407,333 patients (0.18% prevalence) with a 19:1 female-to-male ratio. Patients in the 41–55 age groups had the highest prevalence and Hispanic and Asian patients were three times more likely to be represented than white and black patient populations.

Conclusion:

Asian and Hispanic race and a 41–55 year age group are correlated with a significantly greater prevalence of melasma. The prevalence rate for melasma in this database may be far lower than prior reported rates due to incorrect or missed coding within this database, which is billing code dependent.
Comparative Evaluation of Titanium-platelet-rich Fibrin and Leukocyte-platelet-rich Fibrin – A Scanning Electron Microscopic Study
Authors: Malgikar Suryakanth , Sisinty Vidya Sagar
Published: December 2023

ABSTRACT

Background:

Titanium-prepared platelet-rich fibrin (T-PRF), a new autologous platelet-rich fibrin (PRF) product, is based on the hypothesis that titanium tubes may be more effective in activating platelets when compared with Choukroun’s leukocyte and PRF (L-PRF) method. In this study, we aimed to define the structural characteristics under scanning electron microscopy of T-PRF and compare it with L-PRF.

Materials and Methods:

Blood samples were collected from 10 healthy volunteers. The blood samples were drawn using a 10 ml syringe. A volume of 9 ml was transferred to a dry glass tube, and 9 ml was transferred to a titanium tube and centrifuged. Half of each clot (i.e. after centrifugation, the T-PRF and L-PRF clots were collected) samples were processed with a scanning electron microscope analysis.

Results:

The T-PRF samples seemed to have a highly organized network with continuous integrity compared to the other L-PRF samples.

Conclusion:

Histomorphometry analysis showed that the T-PRF fibrin network covers a larger area than the L-PRF fibrin network, and also, fibrin seemed thicker in the T-PRF samples. The platelet activation by titanium seems to offer some high characteristics to T-PRF.

CLINICAL RELEVANCE TO INTERDISCIPLINARY DENTISTRY

Titanium-prepared platelet-rich fibrin (T-PRF), A new autologous platelet fibrin rich product can be used in regeneration of pulpal and periodontal tissues.
