Published: June 2023

It is a well-established fact that inadequate Vitamin D (Vit-D) levels have negative effects on the development and progression of malignant diseases, particularly cancer. The purpose of this paper was to elucidate the effects of Vit-D intake and serum 25-hydroxyvitamin-D (25(OH)D) levels on cancer incidence and mortality, the current evidence in this field, and the biases of this evidence, using the meta-meta-analysis method. Meta-analyses focusing on Vit-D intake, serum 25(OH)D levels, and cancer risk/mortality were identified. A structured computer literature search was undertaken in PubMed/Medline, Web of Science (WoS), and Scopus electronic databases using predetermined keyword combinations. Primary and secondary meta-meta-analyses were carried out, combining odds ratios (ORs), risk ratios (RRs), and hazard ratios (HRs) for outcomes reported in selected meta-analyses. A total of 35 eligible meta-analyses (59 reports yielded from these studies) assessing the association between Vit-D and cancer incidence and/or mortality were included in this study. In the pooled analysis, higher Vit-D intake and serum 25(OH)D levels were associated with lower cancer risk (OR = 0.93, 95% confidence interval (CI): 0.90–0.96, p < 0.001; OR = 0.80, 95% CI: 0.72–0.89, p < 0.001, respectively) and cancer-related mortality (RR = 0.89, 95% CI: 0.86–0.93, p < 0.001; RR = 0.67, 95% CI: 0.58–0.78, p < 0.001, respectively). When meta-analyses whose primary reports included only randomized controlled trials were pooled, there was no significant association between Vit-D intake and cancer risk (OR = 0.99, 95% CI: 0.97–1.01, p = 0.320). In subgroup analysis, Vit-D consumption was associated with a significant decrease in colorectal and lung cancer incidence (OR = 0.89, 95% CI: 0.83–0.96, p = 0.002; OR = 0.88, 95% CI: 0.83–0.94, p < 0.001, respectively). Taken together, both Vit-D intake and higher 25(OH)D levels may provide remarkable benefits in terms of cancer incidence and mortality; however, careful evaluation according to cancer types is critically important and recommended.

Published: June 2023

The aim of the present study was to compare disordered eating (DE), body image, and sociocultural and coach-related pressures between athletes of different age groups (adolescents and adults) and between athletes participating in weight-sensitive (WS) and less WS groups. A total of 1003 athletes participated in this study. The age range of the sample was 15 to 44 years, and the mean age was 18.9 ± 5.8 years (51.3% were female). Athletes who voluntarily agreed to participate in the study were provided with the study measures on DE, body image and sociocultural attitudes towards appearance. Vomiting, laxative misuse and excessive exercise were more prevalent in adolescent female athletes than adults, while dietary restraint was more common in adult male athletes than adolescents. Adolescent female athletes experienced higher sociocultural (family, peers) and sport-related (coach) pressures and a less positive body image compared with adult female athletes. Adult male athletes experienced higher overweight preoccupation, more DE and unhealthy eating habits, and engaged in more frequent self-weighing behaviour compared with adolescent males. When the effect of weight sensitivity in sports was tested, a higher prevalence of DE and overweight preoccupation, more frequent self-weighing, and higher body-image-related pressure from coaches were observed in female athletes participating in aesthetic weight-sensitive (WS) sports as compared with those participating in less WS sports. No differences in positive body image were observed in female WS and less WS sports. Special DE prevention and positive body image promotion programs are necessary for female competitive athletes and parents of adolescent female athletes, especially those participating in aesthetic ones. For adult male athletes, special programs aiming to promote healthy eating should be implemented to prevent DE and body image concerns. Special education about DE prevention is compulsory for coaches who train female athletes.

The very-low-calorie KD (VLCKD) is characterized by a caloric intake of under 800 kcal/day divided into less than 50 g/day of carbohydrate (13%) and 1 to 1.5 g of protein/kg of body weight (44%) and 43% of fat. This low carbohydrate intake changes the energy source from glucose to ketone bodies. Moreover, clinical trials have consistently shown a beneficial effect of VLCKD in several diseases, such as heart failure, schizophrenia, multiple sclerosis, Parkinson’s, and obesity, among others. The gut microbiota has been associated with the metabolic conditions of a person and is regulated by diet interactions; furthermore, it has been shown that the microbiota has a role in body weight homeostasis by regulating metabolism, appetite, and energy. Currently, there is increasing evidence of an association between gut microbiota dysbiosis and the pathophysiology of obesity. In addition, the molecular pathways, the role of metabolites, and how microbiota modulation could be beneficial remain unclear, and more research is needed. The objective of the present article is to contribute with an overview of the impact that VLCKD has on the intestinal microbiota composition of individuals with obesity through a literature review describing the latest research regarding the topic and highlighting which bacteria phyla are associated with obesity and VLCKD.
The Role of the Photon Counting Loss Effect in Time-Resolved Measurements of Fluorescence Anisotropy

Published: June 2023

Determining the rate of rotation of molecules from their fluorescence anisotropy decay curves is a powerful method for studying molecular systems in biological applications. The single photon count detection systems used for this have a nonlinear dependence of the photon counting rate on the fluorescence intensity flux (photon counting loss effect), which can lead to a number of artifacts. Using metal complexes of phthalocyanines as a test sample, we have shown that such a nonlinearity can cause distortions in the determination of the fluorescence anisotropy lifetime and the asymptotic fluorescence anisotropy. We also assessed the dependence of the described phenomena on temperature and estimated the manifestations of the photon counting loss effect in the case of photobleaching of the fluorophores.

Late Pleistocene to Holocene Palaeohydrological History of the Thermal-Spring-Fed Lake Pețea (NW Romania) Revealed by Radiocarbon Dating and Complex Sedimentological Investigations
Authors: Gulyás Sándor , Sümegi Pál
Published: June 2023

Understanding sedimentation processes in response to past hydrogeological and climatic changes and capturing millennial-scale variations is a key focus of lacustrine paleoenvironmental research. This study presents the first high-resolution chronology and sedimentary data for the small thermal-spring-fed Lake Pețea, NW Romania, and unravels the evolutionary history of the lake harboring a unique endemic fauna. Its small size and single source of water make it particularly sensitive to hydrological changes. In the recent past, over-exploitation of the thermal water has led to the complete drying up of the lake and the extinction of its fauna. Nevertheless, past spatio-temporal variation of environmental factors, in particular the fluctuation of lake levels and water temperature, must have had a significant impact on the survival and evolution of the endemic mollusk fauna. This fact makes this study particularly important. Based on our results, a three-stage sedimentary evolution occurred, mainly controlled by major climate-driven hydrological changes also seen in regional records, i.e., 17.5–14.5 ka shallow eutrophic lake, 14.5–5.5 ka oligotrophic carbonate-rich lake, and 5.5–0.5 ka shallow eutrophic lake. A major lowstand at 11.7–10.2 ka due to drier climate was followed by progressively rising water levels up to 5 ka followed by a drop. The main control on lake level fluctuations and sedimentary phases was the varying input of thermal water due to recurring increased/decreased recharge of the underground shallow karst water system. The driving factor of thermal water discharge was different during the Late Glacial than the Holocene. It was the warming of the climate at 14.5 ka cal BP and melting of regional ice sheets in addition to increased precipitation that created an oligotrophic lake by recharging the underground thermal water system. Conversely, during the Holocene, increasing/decreasing moisture availability driven by major climate forcings was in control of thermal water recharge, erosion, and fluctuating lake levels.
Automatic Post-Stroke Severity Assessment Using Novel Unsupervised Consensus Learning for Wearable and Camera-Based Sensor Datasets

Published: June 2023

Stroke survivors often suffer from movement impairments that significantly affect their daily activities. The advancements in sensor technology and IoT have provided opportunities to automate the assessment and rehabilitation process for stroke survivors. This paper aims to provide a smart post-stroke severity assessment using AI-driven models. With the absence of labelled data and expert assessment, there is a research gap in providing virtual assessment, especially for unlabeled data. Inspired by the advances in consensus learning, in this paper, we propose a consensus clustering algorithm, PSA-NMF, that combines various clusterings into one united clustering, i.e., cluster consensus, to produce more stable and robust results compared to individual clustering. This paper is the first to investigate severity level using unsupervised learning and trunk displacement features in the frequency domain for post-stroke smart assessment. Two different methods of data collection from the U-limb datasets—the camera-based method (Vicon) and wearable sensor-based technology (Xsens)—were used. The trunk displacement method labelled each cluster based on the compensatory movements that stroke survivors employed for their daily activities. The proposed method uses the position and acceleration data in the frequency domain. Experimental results have demonstrated that the proposed clustering method that uses the post-stroke assessment approach increased the evaluation metrics such as accuracy and F-score. These findings can lead to a more effective and automated stroke rehabilitation process that is suitable for clinical settings, thus improving the quality of life for stroke survivors.
Study of the Feasibility of Decoupling Temperature and Strain from a ϕ-PA-OFDR over an SMF Using Neural Networks
Authors: Pedraza Andrés , del Río Daniel , Bautista-Juzgado Víctor , Fernández-López Antonio , Sanz-Andrés Ángel
Published: June 2023

Despite several existing techniques for distributed sensing (temperature and strain) using standard Single-Mode optical Fiber (SMF), compensating or decoupling both effects is mandatory for many applications. Currently, most decoupling techniques require special optical fibers and are difficult to implement with high-spatial-resolution distributed techniques, such as OFDR. Therefore, this work’s objective is to study the feasibility of decoupling temperature and strain out of the readouts of a phase and polarization analyzer OFDR (ϕ-PA-OFDR) taken over an SMF. For this purpose, the readouts will be subjected to a study using several machine learning algorithms, among them Deep Neural Networks. The motivation that underlies this target is the current blockage in the widespread use of Fiber Optic Sensors in situations where both strain and temperature change, due to the coupled dependence of currently developed sensing methods. Instead of using other types of sensors or even other interrogation methods, the objective of this work is to analyze the available information in order to develop a sensing method capable of providing information about strain and temperature simultaneously.

Currently there are various concepts of heat transfer intensification, on the basis of which methods have been developed to increase the heat transfer coefficient in the channels of heat exchange surfaces, which do not lead to significant additional energy costs for flow movement. The article presents the results of an experimental study on the influence of various types of fins on heat transfer processes and hydraulic resistance. The results obtained show that fins in the form of crosses and triangles are the most efficient in terms of heat transfer. However, they create the greatest hydraulic resistance. The largest value of the Nusselt number is relevant for fins type 5 and 6 due to a more active effect on the core of the flow owing to its shape. Fins 7 and 4 have the minimal influence, since they have the ‘smoothest’ shape. Studies have shown that with Reynolds numbers in the range of 13,000–32,000, fins of type 4 and 7 show the greatest resistance. It is shown that it is possible to switch from pipes without fins to pipes with fins by including the coefficient B in the Nusselt equation having a range of 0.03–0.061. It is shown that under certain conditions, heat transfer when using fins can decrease with increasing Reynolds number.
Sinogram Inpainting with Generative Adversarial Networks and Shape Priors
Authors: Valat Emilien , Farrahi Katayoun , Blumensath Thomas
Published: June 2023

X-ray computed tomography is a widely used, non-destructive imaging technique that computes cross-sectional images of an object from a set of X-ray absorption profiles (the so-called sinogram). The computation of the image from the sinogram is an ill-posed inverse problem, which becomes underdetermined when we are only able to collect insufficiently many X-ray measurements. We are here interested in solving X-ray tomography image reconstruction problems where we are unable to scan the object from all directions, but where we have prior information about the object’s shape. We thus propose a method that reduces image artefacts due to limited tomographic measurements by inferring missing measurements using shape priors. Our method uses a Generative Adversarial Network that combines limited acquisition data and shape information. While most existing methods focus on evenly spaced missing scanning angles, we propose an approach that infers a substantial number of consecutive missing acquisitions. We show that our method consistently improves image quality compared to images reconstructed using the previous state-of-the-art sinogram-inpainting techniques. In particular, we demonstrate a 7 dB Peak Signal-to-Noise Ratio improvement compared to other methods.

Published: June 2023

Tungsten carbide nanoparticles (nano-WC) are prevalent in composite materials, and are attributed to their physical and chemical properties. Due to their small size, nano-WC particles can readily infiltrate biological organisms via the respiratory tract, thereby posing potential health hazards. Despite this, the studies addressing the cytotoxicity of nano-WC remain notably limited. To this purpose, the BEAS-2B and U937 cells were cultured in the presence of nano-WC. The significant cytotoxicity of nano-WC suspension was evaluated using a cellular LDH assay. To investigate the cytotoxic impact of tungsten ions (W6+) on cells, the ion chelator (EDTA-2Na) was used to adsorb W6+ from nano-WC suspension. Subsequent to this treatment, the modified nano-WC suspension was subjected to flow cytometry analysis to evaluate the rates of cellular apoptosis. According to the results, a decrease in W6+ could mitigate the cellular damage and enhance cell viability, which indicated that W6+ indeed exerted a significant cytotoxic influence on the cells. Overall, the present study provides valuable insight into the toxicological mechanisms underlying the exposure of lung cells to nano-WC, thereby reducing the environmental toxicant risk to human health.
Maxwell-Dirac Isomorphism Revisited: From Foundations of Quantum Mechanics to Geometrodynamics and Cosmology
Authors: Kholodenko Arkady L.
Published: June 2023

Although electrons (fermions)and photons (bosons) produce the same interference patterns in the two-slit experiments, known in optics for photons since the 17th Century, the description of these patterns for electrons and photons thus far was markedly different. Photons are spin one, relativistic and massless particles while electrons are spin half massive particles producing the same interference patterns irrespective to their speed. Experiments with other massive particles demonstrate the same kind of interference patterns. In spite of these differences, in the early 1930s of the 20th Century, the isomorphism between the source-free Maxwell and Dirac equations was established. In this work, we were permitted replace the Born probabilistic interpretation of quantum mechanics with the optical. In 1925, Rainich combined source-free Maxwell equations with Einstein’s equations for gravity. His results were rediscovered in the late 1950s by Misner and Wheeler, who introduced the word "geometrodynamics” as a description of the unified field theory of gravity and electromagnetism. An absence of sources remained a problem in this unified theory until Ranada’s work of the late 1980s. However, his results required the existence of null electromagnetic fields. These were absent in Rainich–Misner–Wheeler’s geometrodynamics. They were added to it in the 1960s by Geroch. Ranada’s solutions of source-free Maxwell’s equations came out as knots and links. In this work, we establish that, due to their topology, these knots/links acquire masses and charges. They live on the Dupin cyclides—the invariants of Lie sphere geometry. Symmetries of Minkowski space-time also belong to this geometry. Using these symmetries, Varlamov recently demonstrated group-theoretically that the experimentally known mass spectrum for all mesons and baryons is obtainable with one formula, containing electron mass as an input. In this work, using some facts from polymer physics and differential geometry, a new proof of the knotty nature of the electron is established. The obtained result perfectly blends with the description of a rotating and charged black hole.

Published: June 2023

Integrating photovoltaic technology has undergone significant development in recent years, owing to its manifold advantages. One of the most recent domains where this technology has found application is within the transportation sector. The utilization of this technology possesses the potential to initiate a new revolution in transportation by enhancing the range and reducing fuel consumption in vehicles. The performance of these systems is influenced by numerous factors, which have been thoroughly examined in this study. These factors have been categorized into three broad groups: installation site, solar cell characteristics, and environmental conditions. It is important to note that these conditions are inherently interdependent, so this study reveals that the radiation incident on the roof of a van can be 1.09–3.85 times greater than the radiation incident on its sides, according to varying meteorological conditions and different seasons. The current research serves as a valuable foundation for future investigations in this field, offering a targeted and practical overview of the work conducted thus far and summarizing the current state of research.

Published: June 2023

Background: Due to the staggering number of tobacco users in India, it is important to determine the exact mortality and morbidity rates due to tobacco use. This study aimed to estimate deaths, disability-adjusted life years (DALYs), and years of life lost (YLLs) attributable to cigarettes, bidis, and smokeless tobacco (SLT) in India. Methods: Data pooling and meta-analysis were done using case-control studies available on the three types of tobacco products. Health burden was estimated by applying the population attributable fraction (PAF) value to the total disease burden. Findings: A total of 33 studies were included. PAF was calculated for oral and lung cancer as well as ischemic heart disease (IHD) due to cigarettes, oral and lung cancer, IHD, and chronic obstructive pulmonary disease due to bidi, and oral and stomach cancer and IHD due to SLT. Cigarettes resulted in 8.4 million DALYs, 8.26 million YLLs, and 341 deaths; bidis led to 11.7 million DALYs, 10.7 million YLLs, and 478 thousand deaths, and SLTs accounted for 4.38 million DALYs, 4.3 million YLLs, and 171 thousand deaths annually. Conclusion: Evidence of measurable health burden and methodology for calculation for individual states was provided in the study. The generated evidence could be utilized for policy recommendations and revision of the existing taxation norms.

Published: June 2023

Background: During the COVID-19 pandemic, nurses experience a high workload and stressful psychological stimuli that affect their mental and emotional health, which may lead to burnout symptoms. Therefore, this study aimed to analyze the effect of COVID-19 on nurses’ job burnout and investigate its consequences. Methods: The present study is an applied descriptive study, and data collection was performed using surveys. The study was conducted on 107 nurses working in Shahid Mohammadi and Khalij-e-Fars hospitals of Bandar Abbas, Hormozgan. The level of job burnout was measured using the Oldenburg Burnout Inventory (OLBI), job satisfaction by Job Satisfaction Questionnaire, and depression by Beck Depression Inventory (BDI). The data were analyzed via structural equation modeling by PLS 3 software. Results: Overall, the mean job burnout level was higher than the average (3.45). The results, at the 95% confidence level and the significance value of>1.96, showed that poor organizational resources and traumatic events have a direct and significant effect on nurses’ job burnout; however, the impact of workload on job burnout was not confirmed. The results also showed that nurses’ job burnout has a direct and significant relevance with depression, job dissatisfaction, and low quality of care. Conclusion: Poor organizational resources and traumatic events increased job burnout. Job burnout increased depression, and also reduced job satisfaction and quality of care. Situational and personal factors have a significant role in decreasing nurses’ job burnout. It is necessary to provide a better work environment, good intrapersonal relationships, and personal skills training courses.

Published: June 2023

Background: Sodium dodecyl sulfate (SDS) detergent is widely used in tissue decellularization to produce scaffolds for tissue engineering. Despite its strong decellularization, this substance has relatively high toxicity and causes changes in tissue composition. Sodium lauryl ether sulfate (SLES) is a new poly anionic detergent that is less toxic than SDS but weaker than it. The present study aimed to decellularize the intestinal tissue using SDS and SLES solutions, forming a cell scaffold, and examining scaffolds obtained from this tissue. Methods: Eighteen male Sprague-Dawley rats were divided into three groups. The intestines of all rats were removed after anesthesia. In the first group (controls), rats’ intestines were placed in a 10% formalin solution. In the second group, intestines were decellularized using an SLES solution. In the third group animals’ intestines were decellularized using an SDS solution. To evaluate decellularization, samples were stained with hematoxylin-eosin staining and Alcian blue staining for glycosaminoglycans (GAGs), and Masson’s trichrome for collagen fibers. A confocal Raman microscope was used to compare collagen, lipid, GAG, and genetic content. Results: Hematoxylin-eosin staining showed that the nucleus and DNA were removed in the decellularized scaffolds by SDS or SLES. The SLES group, compared to the SDS group, showed fewer changes in the epithelial tissue, and muscle layers in both scaffolds were well preserved. The results of confocal Raman microscopy showed that tryptophan, lipid, glycogen, and protein were broken down by both detergents; however, the residual amount of glycogen was the same in both substances, but disulfide bonds of proteins, hydroxyproline, and lipids in the decellularized intestine with SLES were mostly preserved. Conclusion: Both substances were suitable for intestinal decellularization and removed the overall structure of intestinal tissue, but SLES retained collagen and GAG content better than SDS.
Could Telenutrition Be Applied Interchangeably with the Face-to-Face Interview for Dietary Intake Assessment in Patients with Type 2 Diabetes During the COVID-19 Pandemic?
Authors: Mahmoodi Mohammad Reza , Kazemian Behnaz , Asaadi Shila
Published: June 2023

Background: COVID-19 pandemic has caused limitations, in patients’ accessibility in clinical and research settings. We sought whether telenutrition could be applied interchangeably with face-to-face interview for dietary intake assessment by 24-hour recall in patients with type 2 diabetes mellitus (T2DM) during the COVID-19 pandemic. Methods: Sixty-eight females with T2DM aged 50-55 years were enrolled randomly in a descriptive-analytic cross-sectional study. The patients completed three consecutive 24-hour dietary recalls. The first one was a face-to-face interview, and the subsequent two recalls were conducted by telephone call. The total energy and 18 selected nutrients intake were calculated for the three interviews. Results: The mean (±SD) age of participants was 53.97±2.14 years. The face-to-face interview resulted in significantly higher total energy and 18 selected nutrients intake than the two telenutrition interviews (P value range: 0.031 - 0.001). No significant differences were found between the data provided from the two telenutrition interviews. Conclusion: Telenutrition underreports and underestimates the total energy and nutrient intakes compared with the face-to-face interview in the 24-hour dietary recall. Therefore, it cannot be recommended to be applied interchangeably with a face-to-face interview for dietary intake assessment during the COVID-19 pandemic, especially in patients whose nutrition assessment is of clinical importance. A combination of the two methods using new communication applications (e.g. WhatsApp) may cover the defects of telenutrition method.

Published: June 2023

Background: Liver cancer is the third most common cause of cancer mortality. Artificial intelligence, as a diagnostic tool, can reduce physicians’ working load. However, the main fear is that due to the existence of many causes and factors, liver diseases are not easily diagnosed. This study analyzes liver disease intelligently. Various decision tree models were used in this research. Methods: The records of 583 patients in the North East of Andhra Pradesh, India, registered at the University of California in 2012, were collected. Decision tree models were compared by three measures of sensitivity, accuracy, and area under the ROC curve. Results: In this study, Decision-Stump showed better results than other models. Accuracy, sensitivity, and ROC curve of Decision-Stump were 71.3058, 1, and 0.646, respectively. Conclusion: The superior model with the highest precision is the Decision-Stump model. Therefore, the Decision-Stump model is recommended for liver disease diagnosis. This paper is invaluable for the allocation of health resources for risky people.
Sudden Sensorineural Hearing Loss in a Patient with COVID-19: A Case Report
Authors: Delphi Maryam , Kardouni Maryam
Published: June 2023

Background: Several viral infections may lead to hearing loss. It›s still unknown whether COVID-19 has effects on the auditory system or not. In this regard, to evaluate the possibility of sudden sensorineural hearing loss due to COVID-19, this study aimed to report sudden sensorineural hearing loss (SSNHL) in patients with COVID-19 in Iran. Case Report: The patient was a 7-year-old girl diagnosed with COVID-19 and sensorineural hearing loss. An audiogram revealed normal hearing in the right ear and severe sensorineural hearing loss in the left ear. The tympanometry test result was bilateral type A. The treatment started with prednisolone (1 mg/kg/d). The audiogram of follow-up pure-tone audiometry did not reveal any improvement. Conclusion: SSNHL appears to be a possible complication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. COVID-19 infection could have deleterious effects on cochlear hair cells and eight nerve functions. Therefore, audiological monitoring should be initiated in patients presenting with COVID-19.
A Bibliometric Study on the Top 101 Most-Cited Articles of Dental Journals of the Middle East/North Africa Countries From 2011 to 2021

Published: June 2023

Introduction: This retrospective descriptive study evaluated the Scopus-indexed dental journals and their most-cited documents affiliated with the Middle East and North Africa (MENA) countries from 2011 to 2021. Methods: Dental journals affiliated with MENA countries, their bibliometric indicators (SJR, CiteScore, SNIP, and H-index), and the 101 most cited articles of the considered journals were extracted and studied through descriptive statistics. In addition, the "citation per year" of each top 101 articles was calculated. Spearman’s rho test was used for pairwise comparisons of the correlation coefficient values between each two of the considered bibliometric indicators. Results: The number of citations of the 101 most-cited papers ranged from 35 to 203. The mean (SD) citations of studied articles were 61.33 (37.58) and the median was 46. Furthermore, CiteScore had the highest significant correlation with SJR (r=0.828, P˂0.001). Moreover, the citation per year of the top 101 documents had no significant relationship with any of the journals’ bibliometric indicators. Conclusion: Because journal performance and citation rate are multi-dimensional concepts, a single metric cannot express them thoroughly despite correlations between indices. "European Journal of Dentistry" from Turkey, "Saudi Dental Journal" from Saudi Arabia, and "Iranian Endodontic Journal" and "Journal of Lasers in Medical Sciences" both from Iran had the highest ranks in the SCImago portal and the highest scores in bibliometric indices amongst the MENA dental journals

Background: Oral health conditions are a group of complications that are partially associated with breast cancer (BC) treatments. However, evidence on the sociodemographic risk factors of oral health conditions among BC patients is scarce. This study aimed to investigate the relationship between the socioeconomic status (SES) and dental health in a population of Iranian female BC patients in 2020. Methods: A cross-sectional study was conducted in Kerman, Iran. Indices of decayed, extracted, and filled teeth were measured based on clinical examination by a general dentist. Data were collected through structured face-to-face interviews, review of the patients’ medical records, and clinical examination for six months. Data were analyzed by applying univariate and multivariable generalized negative binomial regression (GNBReg). Data were analyzed using the Stata. Results: Data from 1760 BC patients were collected, 1707 of whom were included in the analysis. The mean age of the participants was 46.3±9.8 years. The mean of the total decayed, missing, and filled teeth, and the number of decayed teeth (DT), missing teeth (MT), and filled teeth (FT) were 12.8±5.8, 3.5±3.1, 4.6±5.2, and 4.6±4.4 teeth, respectively. Regarding SES, the number of participants with high, high-middle, low-middle, and low SES were 421, 432, 395 and 459, respectively. According to univariate analysis, there was no significant difference between different SES in mean DMFT (decayed, missing, and filled teeth), while SES was significantly associated with DT, MT and FT among the study participants. Conclusion: Female BC patients in Iran have lower levels of dental health regardless of their SES. As those from different socioeconomic classes are seeking different and mostly inadequate or unsuitable dental healthcare services, tailored interventional programs are needed to address the dental healthcare needs of patients in each socioeconomic class.

Published: June 2023

Background: Incivility is a kind of disrespect to people. Students and faculty members agree on the growing trend of incivility. Uncivil behaviors in online nursing classes are a serious global issue that can influence the learning-teaching process and threaten patient safety in the clinical setting. This study aimed to identify incivility in the online learning environment from the perspective of nursing faculty members and students. Methods: This descriptive qualitative study was conducted in 2021. A total of 20 participants were selected from among nursing students and faculty through purposive sampling. Data were collected using in-depth semi-structured interviews and analyzed via a qualitative content analysis approach. Results: Data analysis revealed five categories including ghost students, unconditional freedom, disruptive learning behaviors, academic dishonesty, and ignoring the rules of the online learning environment. Conclusion: Incivility in the online learning environment disrupts the teaching-learning process and undermines instructor-student relationships. Given that disrespectful and threatening behaviors, even to a small degree, can significantly affect the learning environment, it is essential to recognize such behaviors. As uncivil behaviors in virtual nursing education can affect education by developing inappropriate behavioral and communication patterns in students, leading to the violation of professional ethics and patients’ rights, it is necessary to pay attention to this critical issue by conducting further studies and designing interventions to correct it.

Published: June 2023

Background: Acute kidney injury (AKI) occurs in 20-50% of patients with cirrhosis and is associated with a poor prognosis. The aim of the study is to identify the baseline factors affecting mortality in these patients at 30 and 90 days. Methods: We enrolled 117 patients with cirrhosis and AKI and followed them up prospectively. Results: Distribution of International club of ascites AKI stages was: 26 (22.03%) stage 1, 59 (50%) stage 2, and 33 (28%) stage 3. Mortalities at 30 and 90 days were 27 (22.8%) and 33 (27.9%) respectively. On multivariate analysis, variables affecting mortality at 30 days were serum creatinine level>2 mg% at 48 hours after AKI development (adjusted OR 7.93, P=0.02) and leukocytosis (total leucocyte count>11000/mm3 ) at admission (adjusted OR 6.54, P=0.002). Only leukocytosis at admission was a predictor of 90 days mortality (adjusted OR 4.76, P=0.01). Though not statistically significant, patients not responding to standard medical treatment had 3 times higher mortality at 30 days, while the maximum AKI stages (2 and 3) had eight times higher mortality at 90 days. Conclusion: In cirrhosis, AKI increases short-term mortality. High serum creatinine at 48 hours affects mortality at 30 days, while leukocytosis at baseline predicts mortality at 30 and 90 days. Progression to a higher AKI stage impacts prognosis.

Published: June 2023

Curriculums are updated according to the educational needs. In the Türkiye context, the high school mathematics curriculum was last updated in 2018. This study aims to compare high school mathematics curriculum documents in Türkiye since the 2005 reform in terms of basic elements of a curriculum (general objectives, content, learning-teaching processes, and assessment-evaluation approaches). In this qualitative study, which adopted a horizontal approach as one of the approaches of comparative studies, data were collected through documents. The data consist of official documents of the high school mathematics curriculums published in 2005, 2011, 2013, and 2018. Curriculum documents were analyzed based on general objectives, contents, learning-teaching processes, and assessment-evaluation approaches of the curriculums. Findings revealed similarities and differences between the basic components and the shortcomings of the curriculums. In particular, the changes in the number of learning objectives and accordingly in the contents were discussed. The pedagogical reasons underlying the radical changes regarding adding new content or removing some content may be a matter of curiosity. Curriculum developers are suggested to include the reasons for these changes.
THE STORY OF SLAUGHTERING COWS IN SURAH AL-BAQARAH
Authors: Afiyah Nur
Published: June 2023

The name of surah al-Baqarah is taken from the story of slaughtering cows, verses 67 to 73. Suppose someone only reads the translation of the Qur'an or reads the Ijmali interpretation, of course. In that case, he will not be able to understand the story coherently because the verse arrangement is reversed. Therefore, it takes the narratological theory of the Qur'an to sequence the story so that it can be understood easily by historical chronology. The study uses a literature review by collecting the commentators, summarized in a book of commentaries. The study results are the story of the slaughter of a cow, starting from verses 72 and continuing with verses 67 to 71. After that, verse 72 is skipped and goes straight to verse 73. So, the chronological sequence of history is 72, 67, 68, 69, 70, 71, and 73. Based on it, al-Baqarah is a cow slaughtered by the Israelites to uncover the case of the murder of a nephew to his uncle. The nephew is the only heir. He could not wait for an inheritance, so he killed his wealthy uncle. He left the trail by placing the corpse in front of someone else's house at night. Then the case of finding the body went viral, and the Israelites accused each other of being confused about finding the culprit. After that, they asked Moses to solve the case; the order came down for the Israelites to slaughter a cow. Then, part of the cow was struck against the corpse, and he got up and said that the killer was his nephew.
