COVID-19 has led to quarantines, isolations, and social separations worldwide. Universities use distance education and blended learning especially for practical courses. The purpose of this study was to investigate the effectiveness of blended learning via Edmodo on students' performance and attitude when learning some fundamental boxing skills. Thirty-two students from 124 enrolled in a boxing sport course were randomly selected. A quasi-experimental design was used by creating a control group and an experimental group. A flipped classroom strategy was used to teach basic boxing skills to the experimental group via Edmodo. The control group was taught via teacher command style. Results of the post-measurements of overall skill performance score indicated that the experimental group outperformed the control group with a large effect size of ([eta][superscript 2] = 0.73). The Edmodo students also demonstrated positive attitudes. A blended learning program via Edmodo influences positively on learning boxing skills and motivates them to learn.

This study aims to evaluate the effect of the interaction between crowdsourcing style and cognitive style on the development of research and scientific thinking skills among postgraduate students at Alexandria University, by designing an e-learning environment. The current research used an experimental approach with a quasi-experimental design. The research sample consisted of a random sample of 80 postgraduate students who were specializing in mathematics, educational technology, and other areas at the Faculty of Education. The measurement tools consisted of an achievement test, the observation card, cognitive style scale, and scientific thinking scale. Data were analyzed using two-way ANOVA analysis of variance. The results showed that there was a significant difference between crowdsourcing patterns (collaborative/competitive) in favor of the collaborative pattern. There was a significant difference between cognitive style (focusing/scanning) in favor of students who adopted the focusing style. There was a significant effect on the interaction between crowdsourcing patterns and cognitive style for each of the cognitive aspects of research skills in global databases through the e-learning environment based on the crowdsourcing pattern, the observation card of students' performance of those skills, and their scientific thinking. The researchers recommend benefiting from the results of the current research in the design of e-learning environments based on crowdsourced (competitive/collaborative) in general, and crowdsourced collaborative in particular because of their impact on the development of achievement, practical performance, and scientific thinking.

Purpose: To evaluate the efficacy of using a customized xenograft shell with a 1:1 mixture of particulate xenograft and autogenous bone for the reconstruction of horizontally deficient anterior maxillary alveolar ridges. Materials and Methods: CBCT images of the atrophic maxilla of eight patients were acquired and generated into 3D models. The data were transferred to a 3D printer for fabrication. During the surgery, xenograft blocks were manually sliced and customized on the 3D-printed models into bone shells. Then they were fixed to the atrophic site, and the gap was augmented with a 1:1 mixture of particulate xenograft and autogenous bone. Results: Clinical assessment showed no adverse effects; however, one patient exhibited wound dehiscence. The mean difference between the preoperative and 6-month postoperative CBCTs showed a net average bone gain of 4.06 mm at 2 mm from the crest and 4.34 mm at 5 mm from the crest, which was statistically significant. On the other hand, a statistically significant graft resorption of 1.41 mm at 2 mm from the crest and 2.19 mm at 5 mm from the crest was found when the mean difference between the immediate and 6-month postoperative CBCTs was calculated. Conclusions: Within the limitations of the study, the use of xenograft shells as a barrier for maxillary alveolar ridge reconstruction is a predictable technique; however, further investigations regarding the required time for graft consolidation are required.

Purpose: Online learning has many limitations in studio-based courses, such as architectural design courses, considering the challenges during post-pandemic. Therefore, this study aims to propose a post-pandemic adopted learning approach, which integrates flipped classrooms (FC) with project-based learning (PBL). In addition, this study evaluates the perceptions of students based on and the effects of the proposed learning approach in architectural design. Design/methodology/approach: This study provides a mixed methodology based on a literature review on the topic to bridge the gaps in previous studies regarding the FC and PBL. In addition, a case study survey including semi-structured interviews, observations questionnaire recruited undergraduate students to generate both qualitative and quantitative data to investigate the perceptions of students based on post-pandemic adopted learning approach. Findings: This study has highlighted the significance of post-pandemic adopted hybrid learning method, especially in architectural education, whereas the research finds that FC is an appropriate solution to improve design courses with online technologies. Practical implications: The proposed approach provides specialists to develop and integrate proposals and strategies to enable a better online practice for students and instructors. The proposed approach can enhance the students' interpersonal skills, hence active online learning related architectural design projects. Originality/value: Recognizing the significance of e-learning in response to the post-pandemic scenario, this study developed and assessed new learning technique that combines online learning with traditional design studios via hybrid learning method.

This study examined whether the five scales of the MUSIC Model of Academic Motivation Inventory produced valid scores when used in university English language courses across four different countries. We surveyed 1,147 students in English language courses in Iran, Mexico, China, and Egypt and analyzed their responses by performing measurement invariance testing using multiple group confirmatory factor analysis. The internal consistency reliability of the five MUSIC Inventory scales was acceptable. The configural, metric, and scalar invariance held across the four countries, providing evidence of construct validity for the five scales. Relationships between the MUSIC Inventory scales and measures of behavioral engagement, disaffection, and achievement provided some evidence of criterion validity, but some inconsistencies with expected relationships were noted. Overall, this study provides validity evidence for using the inventory in English language courses.

Mathematics anxiety (MA) has a debilitating impact on learning, achievement, mental health, and the future career life of students. Though MA is a popular research theme, there is little agreement among researchers regarding the cross-cultural effect of gender. The purpose of this paper was to explore the perceived MA differences among males and females across cultures using the Anxiety Towards Math Scale (ATMS; Muñoz and Mato, 2007). Data were collected between October 2019 and September 2020) from students (N = 4,340) in 12 countries. Using univariate analysis of variance, the results indicate that gender has a significant main effect on MA with females recording higher mean scores than males, [71.816 > 68.118]. Examining the interaction effect of gender and location, significant differences in MA scores exist between males and females across all locations except for Egypt, Malaysia, and Nigeria (Enugu State). Conversely, females reported significantly higher MA scores than males in the rest of the locations, except Iran (Tehran and Qom) and Pakistan (Faisalabad). Gender-based ranking of the top-three locations with high MA scores indicates that females, starting from Malaysia, Thailand (Bangkok), and Nigeria (Enugu State) ranked the highest. Similarly, males beginning from Malaysia, Nigeria (Enugu State), and Thailand (Bangkok) ranked the top-three in MA. The implications are that mathematics teachers need to adopt different culturally-appropriate and gender-focused interventions to support students with MA challenges. Though interpreting the results from this survey need to de done with caution due to the smaller community and national online samples, the role of cross-cultural gender differences in MA cannot be overlooked.

Background: Climate changes have led to health and environmental risks, so it has become essential to measure climate change literacy among the entire population, especially nursing students. The significant role of nursing students in raising public awareness and future healthcare roles emphasizes assessing the predictors of climate change literacy among nursing students. Aims: This study seeks to identify the predictors of climate change literacy among nursing students in A Multi-Site Survey. Design: A multi-site descriptive cross-sectional study adheres to the guidelines outlined in A Consensus-Based Checklist for Reporting Survey Studies collected for five months, from the 1st of July 2023 to November 2023. The study participants comprise 10,084 nursing students from all 27 governments in Egypt. The researcher used the Predictors of Nursing Students' Climate Change Literacy scale in this study. Data was collected, with 25 min average time to complete. Backward multiple linear regression was used to identify these predictors. Results: In the current study, nursing students demonstrated a moderate understanding of climate science (mean score 14.38), communication and advocacy skills (mean score 14.41), and knowledge of adaptation and mitigation strategies (mean score 13.33). Climate health impacts (mean score 17.72) emerged as the domain with the highest level of knowledge. No significant differences in climate literacy were observed across diverse student backgrounds (all p-values were > 0.05). Perceived faculty knowledge of climate change positively correlated with all four domains of climate literacy and emerged as a significant predictor in multiple linear regression analyses (all p-values were < 0.001). Implication. While our findings highlight significant predictors of climate literacy, it is essential to recognize that these results identify associations rather than causal relationships. Based on these associations, it is recommended that nursing professionals be equipped with comprehensive knowledge of climate adaptation strategies to better advocate for and implement effective public health measures.

Egypt has long promised quality basic education. Nevertheless, international and national assessments show poor reading skills. Community schools (CS) are a component of Egypt's Education for All strategy. CS were intended to offer quality education to children who otherwise would have no chance to complete primary school. Previous studies report that academic abilities of Egyptian CS students exceed those of students in mainstream government primary schools. However, over time the education environment in Egypt has changed and the CS have changed with it. The current role and quality of CS education have been questioned. We examine core Arabic language skills of community and mainstream school students in two Upper-Egyptian villages. Results for students in mainstream schools are poor; results for CS students are significantly worse. We examine domains of Arabic language learning to understand specific problem areas.

Background: Gender differences in the diagnosis and treatment of osteoporosis is a relatively common phenomenon, particularly amongst those patients under 80 years of age presenting with fragility fractures. The clinical implications of these findings are that strategies, which tend to focus on osteoporosis management in women, should also pay enough attention to osteoporosis in men. However, there have been questions whether there is a gender difference when setting intervention thresholds for osteoporosis management. This work was carried out aiming to determine the fracture probabilities calculated by FRAX at which therapeutic intervention in older men and women can be considered. Results: Assessment of fracture risk probability thresholds in men revealed that for hip fractures, ROC was 0.754 (95% CI: 0.69–0.817). The sensitivity was 80.5% for threshold probabilities of 2.5%. For the major osteoporosis fracture, ROC was 0.828 (95% CI: 0.694–0.963). The sensitivity was 87.5% for threshold probabilities of 10%. Assessment of fracture risk probability threshold in women ROC was 0.760 (95% CI: 0.691–0.83). The sensitivity was 76.1% for threshold probabilities of 3%. For major osteoporosis fracture, ROC was 0.848 (95% CI: 0.784–0.912). The sensitivity was 87.3% for threshold probabilities of 15%. Conclusion: Operational aspects of osteoporosis management should consider gender specific fracture thresholds. Interventional thresholds were found to be different in men compared to women. This helps to optimise fracture prevention in older men. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine preschool teachers' practices of online learning during the COVID-19 pandemic. A total of 389 preschool teachers from 48 preschools (governmental, experimental, private, and international) in greater Cairo, Egypt responded to a survey in the Fall semester of 2021/2022. The survey was comprised of seven subscales (45 items) that represented teachers' online practices during the pandemic. The multiple linear regression analysis showed that teachers' online learning practices in private and international schools outperformed those in other schools. Teachers who have a teaching experience (11–20 years) outperformed other teachers. Teachers who had training related to online learning showed better practices than other teachers who had not. The multivariate analysis of variance showed that there are statistically significant differences according to the type of school. The study results highlight the need to enhance teachers' online practices during the pandemic to maximise preschool students' learning gains. [ABSTRACT FROM AUTHOR]

Background: Dizziness in elderly patients is classified as a multifactorial geriatric syndrome leading to pathological conditions or changes endemic to the aging process, it is characterized by increased susceptibility to accidents and instability. This is considered a major public health problem. In our study, we assessed age related changes in vestibular function via measurement of combined Vestibular-Evoked Myogenic potentials (VEMPs) as well as Static Subjective Visual Vertical Test (SVVT) for otolith function. Methods: Seventy-five subjects (150 ears) were enrolled in this research. They were categorized into a control group composed of twenty-five adults from 18–40 years and a study group which divided into symptomatic and asymptomatic groups, each group consisted of twenty-five subjects, fifteen subjects aged 55- < 65 years & ten subjects aged 65 to 85 years. All subjects were submitted to combined VEMPs and static SVVT. Results: Detectability of combined VEMPs decreased with age with significant difference among the older age group (> 65- < 85 years) and the subjects aged (55- < 65 years). Percentage of abnormal cVEMPs & oVEMPs latencies and amplitudes was more detected in the older age group than subjects aged (55- < 65 years). The symptomatic group aged > 65 years showed higher percentage of affection of both cVEMPs & oVEMPs, while the younger group aged 55- < 65 showed higher absence of bilateral oVEMPs. There were no statistically significant differences in the asymmetrical ratio of cVEMPs & oVEMPs between elderly and adults. Static SVV perception does not change with age. Conclusions: The elderly showed variable degrees of otolith dysfunction with a high percentage of affection in cVEMPs and oVEMPs. Also, they showed symptoms of imbalance and light-headedness. Static SVVT perception doesn't change with age. [ABSTRACT FROM AUTHOR]

Background: Bovine colostrum (BC) with liposomal delivery system (LDS) is a promising supplement to premature infant formula in absence of mother own milk. We propose that BC with LDS can target multiple etiological factors that threaten the developing retina, making premature infant less liable for retinopathy of prematurity (ROP). The aim of this study was to evaluate the effect of BC with LDS in the prevention of ROP. Methods: This was a single center, randomized, controlled trial. Two hundred and eleven preterm infants of gestational age ≤ 32weeks were admitted to the NICU of Alexandria University Children Hospital, Egypt, and randomly allocated into either non-BC group (n = 105) or BC group (n = 106). Patients in BC group received 3.5 ml /kg/day of BC for 14 days. All patients were monitored for development of ROP, anemia, late onset sepsis (LOS), bronchopulmonary dysplasia (BPD), periventricular leukomalacia (PVL) and necrotizing enterocolitis (NEC), in addition to growth assessment. Multivariate binary logistic regression analysis was performed to determine factors predicting ROP development. Results: Compared with the non-BC group, BC group was associated with a significantly lower incidence of ROP (5/100 vs. 16/100, respectively) with a p-value of 0.033. The administration of BC significantly decreased serum C- reactive protein (CRP) level and increased weight on day-14 of the study in comparison with the CRP level and birthweight at the beginning of study, with Cohen's D= -0.184, D = -2.246, respectively. Patients with suspected sepsis were significantly less in BC than non-BC group, p = 0.004. Patients with BC had significantly higher hemoglobin level on day-14 than non-BC-group, with median (IQR) 12.2 (11.0–13.9) and 11.7 (10.5–12.9), respectively. BC intake is one of factors that decreased development of ROP in univariate analysis. Nevertheless, weight gain and birth weight were the most significant factors affecting ROP development in multivariate-regression model. Conclusion: BC may reduce the incidence of ROP in preterm neonates aged ≤ 32 weeks. This might be due to keeping better Hb level and growth rate, as well as anti-inflammatory properties through its ability to decrease CRP level.

A synthesis of field geological and archaeological surveying, as well as near-surface stratigraphy, provides new insights into the late Quaternary history of this region. We find a long series of alluvial, colluvial, playa, and aeolian deposits that show a complicated history of changes in the late Quaternary climate and environment. In the current study, we summarize the results of a geoarchaeological study that focused on the entire range of landscapes and associated landforms along the fringe of the Libyan Plateau at Umm Dabadib, Kharga Oasis, in the Western Desert of Egypt. We also determined the distribution of the cultural materials of prehistoric sites in different geomorphic settings, including playas, wadis, and dune fields. [ABSTRACT FROM AUTHOR]

Background: We evaluated the noncontrast MRA as an alternate method to CT angiography in assessment of patients with lower limb ischemia, 30 patients were included in a prospective cohort study; they underwent quiescent interval slice selective magnetic resonance angiography (QISS-MRA) and computed tomographic angiography (CTA). The assessment of images was evaluated by two independent consultants. The overall subjective image quality, interobserver and intermodality concordance were calculated. Results: The median acquisition time in QISS-MRA was 20 min (range 18–30 min), The overall subjective image quality was rated similarly with QISS-MRA (3.13 [95% CI 2.84–3.42]) and CTA (3.23 [95% CI 2.94–3.52]; p = 0.08) with interobserver concordance for lesion ratings in QISS-MRA reached (κ = 0.987 (SD 0.006)), while for CTA it was (κ = 0.99 (SD 0.006)), while the intermodality concordance between QISS-MRA and CTA in lesion ratings were calculated on a per segment basis and was (κ = 0.944 (SD 0.013)) for reader 1 and (κ = 0.947 (SD 0.013)) for reader 2, with sensitivity 100% and specificity 97.6% Conclusions: QISS-MRA is a reliable modality for assessment of patients with critical limb ischemia.

Pressure ulcer is considered a common and costly problem in the care of patients. Prevention and management of pressure ulcer are very important due to the high cost of treatment and the adverse consequences of pressure ulcer. This study aimed to evaluate the effect of implementing “aSSKINg” model in reducing pressure ulcer risk. This study used a before- and afterintervention quasi-experimental design. This study was performed on 60 patients who were not randomly selected and assigned in to control and study group. The data collection tool was a 3-part sheet (Braden scale, skin health assessment, and Pressure ulcer assessment). The incidence of pressure ulcer was 19 (60.0%) in the control group versus 9 (30.0%) in the study group with statistical significant differences. The most common site of pressure ulcer was coccyx (6 [31.6%]) in the control group and Heel (3 [33.3%]) in the study group. The application of “aSSKINg” model in the patients with pressure ulcers is effective in reducing the incidence and severity of pressure ulcers. [ABSTRACT FROM AUTHOR]

Purpose: To investigate effectiveness of the ABCDEF bundle to manage and prevent delirium. Background: ICU delirium is a common hospital problem that 80% of critically ill patients in the ICU experience. The ABCDEF bundle is one of the tools that included in Delirium guidelines to manage critically ill patients. Research design: Pre- and post intervention a quasiexperimental design was utilized in the present study. Setting: This study was conducted in the intensive care units of Assiut University Hospital. Methods: A total of 60 mechanically ventilated patients were recruited using inclusion and exclusion criteria. The ABCDEF bundle was implemented every day for the first 7 days of ICU admission, and patient sedation and delirium status were assessed using the Confusion Assessment Method for the Intensive Care Unit (CAMICU). Sedation instrument measures were utilized in data collection. Results: Significant differences were found in the incidence of delirium: 20% in the study group versus 70% in the control group. The increased mean of days without delirium ICU stay was 4.6333 in the study group and 1.1000 in the control group, with P value = .001. Conclusion: The mechanically ventilated patients exposed to the implementation of the ABCDE bundle experienced fewer delirium signs than before the ABCDE bundle was implemented.

Background: Laryngoscopy is a diagnostic procedure utilized in critical care to examine and visualize the larynx through the diversion of upper airway structures. Its primary functions are airway management and tracheal intubation. The objective of this study was to detect the predictors of laryngeal exposure during microlaryngeal surgery (MLS). Methods: An analytical cross-sectional study was conducted on a consecutive sample of 100 patients presenting laryngeal lesions that were trans-orally microsurgeries to treat various glottic diseases (biopsies revealed 68% benign lesions such as vocal fold polyps, cysts, and nodules, and 32% glottic masses) and prepared for MLS. Results: This study included 100 patients presenting laryngeal lesions from both sexes with the age of 47.0 ± 14.7 years, in multivariate logistic regression analysis, all these parameters were significant predictors for Cormack–Lehane and Italian Grading (P < 0.05). Body mass index (BMI) (OR = 3.449, 95% CI = 2.463–8.187), mandibular protrusion test (OR = 2.981, 95% CI = 1.922–4.044), mento-sternal length (OR = 3.722, 95% CI = 1.980–7.794), and atlanto-occipital joint (AOJ) extension (OR = 1.572, 95% CI = 1.865–4.263). Cormack–Lehane and Italian Grading was significantly associated with BMI, mandibular protrusion test, Mallampati Index, mento-thyroid, mento-sternal length, and AOJ extension, it increased with BMI of > 35, with more protruded mandible (class C), higher Mallampati Index (class III) and shorter mento-sternal distance (≤ 12.5 cm). Conclusions: During microlaryngeal surgery, BMI, mandibular protrusion test, Mallampati Index, mento sternal and AOJ extension were significant predictors of Cormack–Lehane and Italian Grading which makes it easier for laryngeal exposure.

Introduction: Nurses play a vital role in ensuring effective patient care delivery and organizational productivity. Hence, it becomes imperative to prioritize their psychological well-being and explore how its impairment may be associated with their productivity loss. Aims: The study aims to investigate the relationship between nurses' psychological well-being and their work productivity loss by examining how nurses self-reported their own psychological well-being and work productivity loss. Methods: A descriptive correlational design was conducted at an Egyptian university hospital. A convenience sample of 400 nurses completed two tools: (a) Outcome Questionnaire-45 was used to assess the psychological well-being of nurses and (b) the Work Productivity and Activity Impairment – General Health Questionnaire was used to measure nurses' work productivity. Results: Among the 400 surveyed nurses, 66.7% reported overall poor psychological well-being. Regarding work productivity loss, 22.8% of nurses missed an average of 974.81 work hours due to absenteeism, and 62.0% lost an average of 10,630 work hours due to presenteeism. Additionally, 75.5% experienced impaired daily living activities. Approximately 13.4% of total working hours were missed due to health problems or psychological distress. Regression analysis revealed that poor psychological well-being significantly predicts work productivity loss, accounting for 2.0% of absenteeism, 11.0% of presenteeism, 17.0% of daily activity impairment, and 9.0% of overall productivity loss, with the model being significant (p < 0.01). Conclusion: Nurses often experience poor psychological well-being and distress that hinder their daily activities and cause work productivity loss. Therefore, hospital management should prioritize improving nurses' physical and mental health and bolstering their self-efficacy and resilience to minimize the effects of symptom distress on productivity. Investing in nurses' well-being through managerial caring, organizational support, and fostering a supportive work environment are vital strategies for promoting quality patient care and enhancing their work productivity.

Since the detection of antigenically atypical very virulent Infectious bursal disease viruses (vvIBDV) in Egypt in 1999, the country has been experiencing recurrent outbreaks with high mortality rates and typical gross lesions associated with typical vvIBDV. However, a significant change occurred in 2023, marked by a notable increase in reported subclinical IBDV cases. To evaluate the field situation, samples from 21 farms in 2023 and 18 farms from 2021 and 2022, all of which had experienced IBD outbreaks based on clinical diagnosis, were collected, and subjected to VP2-HVR sequencing. Phylogenetic analysis revealed that all samples collected in 2021 and 2022 clustered with classical virulent strains and vvIBDV. In 2023, one sample clustered with the Egyptian vvIBDV, another with classical virulent IBDV, and the rest with the novel variant IBDV (nVarIBDV) circulating in China. The alignment of deduced amino acid sequences for VP2 showed that all Egyptian classic virulent strains were identical to the Winterfield or Lukert strains, while vvIBDV strains exhibited two out of the three typical residues found in Egyptian vvIBDV, namely Y220F and G254S, but not A321T. Meanwhile, all Egyptian variant strains exhibited typical residues found in nVarIBDV. However, all Egyptian variants showed a mutation at position 321 (321V), which represents the most exposed part of the capsid and is known to have a massive impact on IBDV antigenicity, except for one sample that had 318G instead. This report highlights the emergence of a new variant IBDV in Egypt, clustered with the Chinese new variants, spreading subclinically in broiler farms across a wide geographic area. RESEARCH HIGHLIGHTS New variant IBDV which emerged in Egypt clustered with Chinese nVarIBDV. nVarIBDV spread subclinically across a wide geographic area. Mutation at 321 represents capsid's most exposed part, a defining feature. Antigenically modified vvIBDV still circulating in Egypt with typical lesions. [ABSTRACT FROM AUTHOR]

Background: Since nurses are at the frontline of healthcare delivery, their actions and understanding of the environment have a big impact on how long healthcare systems can last. It is essential to comprehend the elements that impact nurses' sustainability consciousness to encourage ecologically conscious actions in the healthcare industry. Aim: This study aimed to explore the relationship between pro-social leader behaviors and nurses' sustainability consciousness and testify to the mediating role of organizational culture in this relationship. Design: A cross-sectional descriptive correlational design by STROBE criteria was used. Methods and tools: An approach to a judgmental non-probability sampling technique was employed to obtain data from 350 nurses in an Egyptian hospital. Three measurement surveys were employed: Organizational Culture Survey, Prosociality Scale, and, Sustainability Consciousness Questionnaire (SCQ-S). Relationships were shown using structural equation modeling and descriptive and inferential statistics. Results: 53.4% of nurses have high perceptions of organizational culture, and the majority of nurses (85.7%) have high perceptions of prosocial leader behaviors. Furthermore, 60.9% of nurses have high perceptions of sustainability consciousness. Additionally, Prosocial leader behaviors positively correlated with organizational culture (r = 0.129) and nurses' sustainability consciousness (r = 0.274). The indirect effect of prosocial leader behaviors on nurses' sustainability consciousness through organizational culture is calculated by multiplying the coefficients of both direct effects (0.129 * 0.159 = 0.811). This means that for each unit increase in prosocial leader behaviors, we would expect a 0.811 unit increase in nurses' sustainability consciousness through the mediating effect of organizational culture. The model appears to match the data well based on the model fit parameters (CFI = 1.000, IFI = 1.000, RMSEA = 0.114). Conclusions: The study highlights the impact of pro-social leader behaviors on nurses' sustainability consciousness through the organizational culture as a mediating factor. Nursing Implications: Findings from this research can promote environmental stewardship and sustainable practices in the healthcare sector by illuminating the elements that can encourage and support a sustainability-oriented mindset among nurses. To promote a more sustainable future for the nursing profession, the findings can guide activities in nursing education, corporate culture transformation, and leadership development.

Water scarcity is a major challenge for faba bean production, especially in arid and semi-arid regions. This study investigated the effect of deficit irrigation and organic or bio-fertilization on faba bean yield and water use efficiency (WUE). The experiment was conducted in two consecutive winter seasons in Egypt, and the average results of the two seasons were presented because there were no significant differences between the two seasons. The experimental design was split-plot with three replicates in each season. The main plots were assigned to the amounts of irrigation water [3330 m3 ha−1 (I1), 2830 m3 ha−1 (I2), and 2330 m3 ha−1 (I3)] and the subplots were devoted to the fertilization treatments [control, humic acid (HA), fulvic acid (FA), and effective micro-organisms (EM)]. The results showed that the plant height and branch numbers were increased by 139.95 and 242.03%, respectively, for HA at irrigation treatment of I2 over the control. Adding HA increased chlorophyll and protein contents by 209.04 and 295.46%, respectively, over the control at irrigation regime of I2. Adding HA significantly increased pods number, pods weight per plant, and total green yield by 380.21, 314.51, and 420.28%, respectively, over the control. The WUE value was 4.51 kg m−3 by adding HA under deficit irrigation I2 compared to irrigation I3 (2.64 kg m−3) while the WUE value was 4.58 kg m−3 at normal irrigation (I1). Overall, the application of organic or bio-fertilizers, especially humic acid, could mitigate the negative effects of deficit irrigation and improve faba bean yield and WUE. [ABSTRACT FROM AUTHOR]

Artificial intelligence (AI) technology has expanded its potential in environmental and renewable energy applications, particularly in the use of artificial neural networks (ANNs) as the most widely used technique. To address the shortage of solar measurement in various places worldwide, several solar radiation methods have been developed to forecast global solar radiation (GSR). With this consideration, this study aims to develop temperature-based GSR models using a commonly utilized approach in machine learning techniques, ANNs, to predict GSR using just temperature data. It also compares the performance of these models to the commonly used empirical technique. Additionally, it develops precise GSR models for five new sites and the entire region, which currently lacks AI-based models despite the presence of proposed solar energy plants in the area. The study also examines the impact of varying lengths of validation datasets on solar radiation models' prediction and accuracy, which has received little attention. Furthermore, it investigates different ANN architectures for GSR estimation and introduces a comprehensive comparative study. The findings indicate that the most advanced models of both methods accurately predict GSR, with coefficient of determination, R2, values ranging from 96% to 98%. Moreover, the local and general formulas of the empirical model exhibit comparable performance at non-coastal sites. Conversely, the local and general ANN-based models perform almost identically, with a high ability to forecast GSR in any location, even during the winter months. Additionally, ANN architectures with fewer neurons in their single hidden layer generally outperform those with more. Furthermore, the efficacy and precision of the models, particularly ANN-based ones, are minimally impacted by the size of the validation data sets. This study also reveals that the performance of the empirical models was significantly influenced by weather conditions such as clouds and rain, especially at coastal sites. In contrast, the ANN-based models were less impacted by such weather variations, with a performance that was approximately 7% better than the empirical ones at coastal sites. The best-developed models, particularly the ANN-based models, are thus highly recommended. They enable the precise and rapid forecast of GSR, which is useful in the design and performance evaluation of various solar applications, with the temperature data continuously and easily recorded for various purposes.

This study aimed to investigate the effect of a program based on English digital stories on second-year preparatory pupils' writing performance and reflective thinking. Two writing performance tests (pretest and posttest) as well as a reflective thinking test were prepared by the researchers. Two 2nd-year intact classes from El Sadat Prep School for Girls constituted participants of the study: one as a control group (N = 32) and the other as an experimental group (N = 30). All participants were pretested on writing performance and reflective thinking and no significant differences were found between the control group and the experimental group. This ensured that the two groups were fairly equivalent on writing performance and reflective thinking before the treatment. The experiment lasted for three months. During this period, pupils of the experimental group created their digital stories individually, presented them in front of their peers, and reflected on their experience while creating and presenting their own digital stories. On the completion of the experiment, all participants were posttested. An independent samples t-test confirmed that a statistically significant difference existed between the mean score of the control group and that of the experimental group (t = 7.738, p <0.05) in writing performance posttest while no significant difference existed between the mean score of the control group and that of the experimental group (t = 1.920, p >0.05) in reflective thinking posttest. It was concluded that digital stories had a significant effect on the writing performance, but not on the reflective thinking, of 2nd-year prep school pupils.

The present study explored listening strategy use among a group of Egyptian EFL college sophomores (N = 84). More specifically, it aimed to identify 1) the strategies used more often by participants, 2) the relationship between listening strategy use, and listening comprehension and self-efficacy, and 3) differences in listening comprehension and self-efficacy between students with high and low strategy frequency. A Listening Comprehension Test adapted from paper-based Longman TOEFL test was used to assess participants' listening comprehension. Listening strategy use and self-efficacy about listening were assessed by two instruments developed by the researcher based on relevant literature: a Listening Strategy Questionnaire and a Self-efficacy Questionnaire. Descriptive statistics, correlation coefficients and t-test for independent samples were computed to answer the research questions. Results revealed that cognitive strategies were used more often by participants, followed by metacognitive and socioaffective strategies. Listening strategies correlated significantly with both listening comprehension and self-efficacy. Except for socioaffective strategies, participants with high frequent overall strategy use, cognitive strategies and metacognitive strategies outperformed their counterparts with low frequency in both listening comprehension and self-efficacy. Implications and suggestions for further research are reported.

Parents' socioeconomic status is mainly impact their children health outcomes, cognitive, social and emotional development. It also had a great impact on children health-related knowledge, health-related attitudes, health-related communication, health-related behavior, and self-efficiency level. Enhancing health literacy domains are the keystone in health promotion. Health literacy has become an important public health issue today. It considered as an indicator of development in modern political science. This study aimed to assess the correlation between parents' socioeconomic status and health literacy domains among Shokrof preparatory school students. 50 students were chosen by systematic random sample method from Shokrof preparatory school.

This paper discusses the geochemical constraints on genesis of dispersed mineralized quartz-fluorite veins (QFV) at south west Sinai Peninsula, Egypt. These veins range from colorless to pale to deep violet in color and extend continuously and/or discontinuously in NE-SW, E-W, N-S, and NW-SE trends. They exhibit varying thicknesses ranging from a few centimeters to approximately 0.3 m. The scanning electron microscope (SEM) analysis has revealed the existence of secondary uranium minerals, notably kasolite Pb(UO2)SiO4.(H2O), in association with other minerals such as galena (PbS), atacamite (Cu2Cl(OH)3), and fluorite (CaF2) within the quartz-fluorite veins (QFV). Furthermore, the SEM analysis indicates a significant presence of fluorine incorporated into the biotite lattice of the host granitic rocks. Geochemically, there is a reasonable difference between the host granitic rocks and QFV, especially, silica and alumina contents. Also, some trace elements experienced enrichment in QFV such as Cu, U, Pb and Ag. The chondrite normalized pattern of QFV rare earth elements (REE) shows conspicuous negative Tb anomalies while the host rocks showed negative Eu anomalies. It is noticeable that there is a closed relation between uranium and fluorine in QFV. The Th/U ratios are < 1 in QFV samples indicating that the QFV had not been derived from magmatic origin. Furthermore, the REE and the mineral assemblages of QFV imply to hydrothermal origin (meteoric water) at shallow depth and low temperature < 200 °C under oxidation condition (epithermal genesis).

Background: Saidi sheep are the most abundant ruminant livestock species in Upper Egypt, especially in the Assiut governorate. Sheep are one of the most abundant animals raised for food in Egypt. They can convert low-quality roughages into meat and milk in addition to producing fiber and hides therefore; great opportunity exists to enhance their reproduction. Saidi breed is poorly known in terms of reproduction. So this work was done to give more information on some hormonal, oxidative, and blood metabolites parameters in addition to histological, histochemical and immunohistochemical investigations of the ovary during follicular phase of estrous cycle. The present study was conducted on 25 healthy Saidi ewes for serum analysis and 10 healthy ewes for histological assessment aged 2 to 5 years and weighted (38.5 ± 2.03 kg). Results: The follicular phase of estrous cycle in Saidi sheep was characterized by the presence of ovarian follicles in different stages of development and atresia in addition to regressed corpus luteum. Interestingly, apoptosis and tissue oxidative markers play a crucial role in follicular and corpus luteum regression. The most prominent features of the follicular phase were the presence of mature antral (Graafian) and preovulatory follicles as well as increased level of some blood metabolites and oxidative markers. Here we give a new schematic sequence of ovarian follicles in Saidi sheep and describing the features of different types. We also clarified that these histological pictures of the ovary was influenced by hormonal, oxidative and blood metabolites factors that characterizes the follicular phase of estrous cycle in Saidi sheep. Conclusion: This work helps to understanding the reproduction in Saidi sheep which assist in improving the reproductive outcome of this breed of sheep. These findings are increasingly important for implementation of a genetic improvement program and utilizing the advanced reproductive techniques as estrous synchronization, artificial insemination and embryo transfer.

More than half of the world population lives in Asia and hypertension (HTN) is the most prevalent risk factor found in Asia. There are numerous articles published about HTN in Eastern Mediterranean Region (EMRO) and artificial intelligence (AI) methods can analyze articles and extract top trends in each country. Present analysis uses Latent Dirichlet allocation (LDA) as an algorithm of topic modeling (TM) in text mining, to obtain subjective topic-word distribution from the 2790 studies over the EMRO. The period of checked studied is last 12 years and results of LDA analyses show that HTN researches published in EMRO discuss on changes in BP and the factors affecting it. Among the countries in the region, most of these articles are related to I.R Iran and Egypt, which have an increasing trend from 2017 to 2018 and reached the highest level in 2021. Meanwhile, Iraq and Lebanon have been conducting research since 2010. The EMRO word cloud illustrates 'BMI', 'mortality', 'age', and 'meal', which represent important indicators, dangerous outcomes of high BP, and gender of HTN patients in EMRO, respectively.

Background: Rectal cancer is the most prevalent gastrointestinal tumor. Early diagnosis, accurate staging as well as early treatment are the keys for improving the five-year survival rate. The objective of this research is to assess the effectiveness of diffusion-weighted MRI (DWI) in identifying lymph nodes and distinguishing between benign and metastatic nodes throughout the first stage of primary rectal cancer. Results: The study showed that mean ADC value was significantly higher in mucinous carcinoma (1.72 ± 0.36 × 10–3 mm2/sec) than that in non-mucinous carcinoma (0.981 ± 0.276 × 10–3 mm2/sec) with a cutoff value of (1.3 × 10–3) mm2/s which was the precise value to produce high sensitivity, specificity and accuracy of 93%, 94%, and 94%, respectively. ADC analysis showed either intermediate or low signal in 49 (70%) and high signal in 21 (30%) L.Ns. Mean ADC value showed a significant reduction in malignant L.Ns (1.01 ± 0.54 × 10–3 mm2/sec) compared to benign L.Ns (1.51 ± 0.51 × 10–3 mm2/sec), AUC of 0.674 (P = 0.008) and a cutoff value of 0.987 × 10–3 mm2/s with sensitivity, specificity and accuracy of 44.4%, 91.2% and 67.5%, respectively. The mean L.N /tumor ratio was 1.65 ± 0.73 in benign L.Ns and 1.06 ± 0.37 in malignant L.Ns. Conclusions: In rectal cancer, there was a significant difference between benign and malignant L.Ns regarding diffusion result, L.Ns size, shape, and margin. The study demonstrated the effectiveness of DWI in diagnosing lymph node metastasis in colorectal cancer; true diffusion restriction was significantly noted in malignant L.Ns compared to benign L.Ns. Mean ADC value showed a significant reduction in malignant L.Ns compared to benign L.Ns. L.N/tumor ratio showed a significant reduction in malignant L.Ns compared to benign L.Ns.

Background: The primary causative agent of the COVID-19 pandemic is the newly identified severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). After being identified in the Chinese city of Wuhan, SARS-CoV-2 quickly spread to every country worldwide. The highly mutated SARS-CoV-2 variant B.1.1.529 (Omicron) has the ability to evade the neutralizing antibodies produced by vaccines. This is because the immune response generated by the vaccines is focused on a specific group of receptor-binding domain (RBD) epitopes. The objective of this work is to establish a systematic protocol for isolating, cultivating, and inactivating the SARS-CoV-2 Omicron variant in cell lines without causing any genetic alterations. This is done to develop an inactivated vaccine and make it ready for future pre-clinical trials in animal models. Material and methods: This investigation involves the collection of nasopharyngeal swabs (n = 40) from individuals who are suspected to have COVID-19. The molecular identification of SARS-CoV-2 was achieved by Real-Time Quantitative Reverse Transcription PCR (RT-qPCR). Whole genome sequencing (WGS) has been performed for all collected samples (n = 40). The determination of clade assignment, Pangolin lineages, mutation calling, and phylogenetic placement was performed. We selected only one sample for our candidate vaccine, which has the lowest Ct value and represents the most common strain among all the collected samples. The selected virus sample was cultured on the Vero cell line for 7 continuous passages. The confirmation of SARS CoV-2 propagation was based on the data obtained from both RT-qPCR and the observation of cytopathic effect (CPE). The tissue culture infective dose 50% (TCID50) was determined to examine the growth kinetics for each passage in the tissue culture. The genetic stability of our selected sample for the vaccine candidate was investigated by performing whole genome sequencing (WGS) of the propagated virus. Furthermore, SARS-CoV-2 was fully inactivated by chemical means utilizing beta-propiolactone (βPL), and the overall protein content was assessed. Result: Finally, we will possess a genetically consistent, inactivated form of the SARS CoV-2 Omicron variant, specifically clade 22B and Pango lineage BA.5.2. Conclusion: This inactivated variant will have a known titer and total protein content, making it suitable for further examination in a pre-clinical study aimed at creating an inactivated vaccine for the SARS CoV-2 Omicron variant that was isolated in Egypt.

Background: The omicron variants have been classified as variants of concern by the world health organization due to their initial emergence with a notable mutations that affect on the transmissibility, immune escape and virulence of the SARS-CoV-2 virus. We conducted a cross-sectional analysis study to detect the most common strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Egypt during the 4th wave of the COVID-19 pandemic and used the next genaration sequencing to characterize the SARS CoV-2 omicron variant genome and find the significant mutation influencing the virus's virulence, immune evasion, and transmissibility. Material and methods: This study started during the 4th wave of the COVID-19 pandemic by collecting nasopharyngeal swabs (n = 39) from individuals having COVID-19 symptoms. SARSCoV-2 was molecularly identified using reverse transcription PCR (RT-PCR). For every sample, whole genome sequencing (WGS) was carried out using next generation sequencing Illumina Iseq100 system. Clade assignment, Pangolin lineages, phylogenetic placement, and mutation calling were all carried out using Nextclade tool V3.4.0, Coronavirus Typing Tool V 1.25 and CoVsurver mutation application. Result: Sequencing data analysis proved that all the involved samples in the study belong to the Omicron variant with different clade and Pangolin lineage, the most common strain in Egypt during the 4th wave of the COVID-19 pandemic was Omicron clade 22B and BA.5.2 Pango lineage. Mutation analysis showed that the S gene of the omicron variant accumulated with significant mutations that affect viral immune escape. Conclusion: The omicron variant in Egypt during the 4th wave of the pandemic showed a high ability to escape from the immune system because of newly mutation on the antibodies recognized sites of the S gene, so it is very important to perform continuous monitoring for omicron genome mutations using next-generation sequencing to help the scientific community in the development of appropriate vaccine for this variant.

Recently, Egypt has recognized the pivotal role of High Performance Computing in advancing science and innovation. Additionally, Egypt realizes the importance of collaboration between different institutions and universities to consolidate their own computational and data resources into a unified platform to serve different disciplines (e.g., scientific, industrial, governmental). Otherwise, additional resources would be needed to be purchased with the associated cost, effort, and time difficulties (e.g., setup, administration, maintenance, etc.). Thus, this paper delves into the architecture and capabilities of the EN-HPCG grid using two different workload management systems: (i) Slurm (Open-Source) and (ii) PBS Pro (Licensed). This paper compares the performance of the grid between Slurm and PBS Pro in specific high-throughput computing (HTC) applications using the NAS Grid parallel benchmark (NGB) to determine which workload manager is more suitable for EN-HPCG. The evaluation includes grid-level performance metrics such as throughput, and the number of tasks completed as a function of time. Also, the presented methodology aims to assist potential partners in their decision-making process to join the EN-HPCG grid, with a focus on the site speed-up metric. Our results showed that, unless an open-source solution without cost and license problems is an obligation (in which case, Slurm is the viable solution), then it is not advisable to integrate a cluster with high-speed hardware with a cluster possessing outdated hardware when using the Slurm scheduler. In contrast, the PBS Pro scheduler takes into account online decision-making in a dynamic environment using a unified grid. [ABSTRACT FROM AUTHOR]

Background: Gamification research and practice have gained popularity, but there is a lack of experimental and field evidence regarding the effectiveness of specific design elements and their use contexts especially in developing countries. Aim: This research aimed to measure the effect of gamifying digital learning environments and compare the effects of badges and leaderboards on the development of cognitive and achievement motivation of elementary school students. Method: A gamified environment focused on the circulatory system and employing interactive storytelling was developed. It was tested through an in-field experiment at an elementary school in Egypt. The research sample was of 30 students in the 5th grade, divided into two equal experimental groups (badges - leaderboard). Results: The results indicated an increase in cognitive and achievement motivation among students in both experimental groups. However, there were no significant differences in the effects of badges and leaderboards on the cognitive and achievement motivations of the participants in the two experimental groups. Conclusions: These findings suggest that the effects of gamification are more likely due to the holistic design and novelty, rather than the specific use of a specific game element.

Objective: In epilepsy, early diagnosis, accurate determination of epilepsy type, proper selection of antiseizure medication, and monitoring are all essential. However, despite recent therapeutic advances and conceptual reconsiderations in the classification and management of epilepsy, serious gaps are still encountered in day‐to‐day practice in Egypt as well as several other resource‐limited countries. Premature mortality, poor quality of life, socio‐economic burden, cognitive problems, poor treatment outcomes, and comorbidities are major challenges that require urgent actions to be implemented at all levels. In recognition of this, a group of Egyptian epilepsy experts met through a series of consecutive meetings to specify the main concepts concerning the diagnosis and management of epilepsy, with the ultimate goal of establishing a nationwide Egyptian consensus. Methods: The consensus was developed through a modified Delphi methodology. A thorough review of the most recent relevant literature and international guidelines was performed to evaluate their applicability to the Egyptian situation. Afterward, several remote and live rounds were scheduled to reach a final agreement for all listed statements. Results: Of 278 statements reviewed in the first round, 256 achieved ≥80% agreement. Live discussion and refinement of the 22 statements that did not reach consensus during the first round took place, followed by final live voting then consensus was achieved for all remaining statements. Significance: With the implementation of these unified recommendations, we believe this will bring about substantial improvements in both the quality of care and treatment outcomes for persons with epilepsy in Egypt. Plain Language Summary: This work represents the efforts of a group of medical experts to reach an agreement on the best medical practice related to people with epilepsy based on previously published recommendations while taking into consideration applicable options in resource‐limited countries. The publication of this document is expected to minimize many malpractice issues and pave the way for better healthcare services on both individual and governmental levels. [ABSTRACT FROM AUTHOR]

Aim and objectives: This study evaluated the awareness, knowledge, and attitude regarding forensic odontology (FO) among dental students and graduates at Beni-Suef University and Badr University in Cairo, Egypt. Methods: This cross-sectional study included 316 dentists and dental students in their final year of undergraduate study. An online self-administered questionnaire in English was used to obtain participants' responses. Results: Less than half of the participants (47.5%) were aware of the branch of dentistry named FO. The highest percentages of correct answers in the knowledge assessment were reported in dental age estimation questions, while the lowest percentages were in items related to the use of FO in confirming sexual abuse and using palatal rugae as a marker in forensic identification. The most common source of knowledge was the internet (52.0%). Only 11.1% of the participants received FO courses in their colleges. Studying FO as a postgraduate course was interesting to 67.4% of the participants. The knowledge score was significantly associated with the participants' gender, graduation status, and educational level. Conclusion: This study revealed a lack of awareness of FO as a branch of dentistry among dental students and dentists in Egypt. Increasing awareness and knowledge of FO could be achieved by integrating FO into the dental curriculum at both undergraduate and postgraduate levels. [ABSTRACT FROM AUTHOR]

The Neoproterozoic granitic rocks of Mount Abu Kibash and Tulayah in the central Eastern Desert of Egypt are of geodynamic interest and provide us with important information about the evolution and growth of the northern part of the Arabian–Nubian Shield (ANS) continental crust. They are primarily composed of granodiorites and syenogranites based on new field, mineralogical, and geochemical analyses. The granodiorites are marked by an enrichment of LILEs such as Sr, K, Rb, Ba compared to HFSEs like Nb, Ta, Ti and show a higher concentration of LREEs relative to HREEs. This composition suggests a subduction-related setting and aligns with the characteristics of subducted I-type granites in the ANS. Chemistry of the analyzed primary amphiboles in the investigated granodiorites support a calc-alkaline nature, mixed source and subduction-related setting. The granodiorites represent an early magmatic phase in this setting, likely formed from a mix of mantle-derived mafic magmas and lower crust material, with subsequent fractional crystallization. On the other hand, syenogranites exhibit high SiO2 (72.02–74.02 wt%), total alkali (7.82–8.01 wt%), and Al2O3 (13.79–14.25 wt%) levels, suggesting their derivation from peraluminous (A/CNK > 1) parental magmas. Their REE-normalized patterns are flat with a pronounced negative Eu anomaly, typical of post-collisional A2-type granites worldwide. These rocks originated from the partial melting of a juvenile lower crustal source (tonalite) in a post-collisional setting, driven by lithospheric delamination that facilitated mantle upwelling and underplating to the lower crust. Interaction between the upwelled mantle and lower crust led to fertilization (enrichment with HFSE and alkalis) of the lithosphere before partial melting. Fractional crystallization coupled with less considerable crustal assimilation are the main magmatic processes during the evolution of these rocks. The transition from subduction to post-collisional setting was accompanied by crustal uplifting, thickening and extensional collapse of ANS continental crust that caused emplacement of large masses of A-type granites in the northern ANS.

Tick-borne diseases in animals are increasing rapidly worldwide, but there is insufficient information about tick-borne diseases infecting dogs in southern Egypt. Thus, in the current study, we detected the presence of Anaplasma marginale (A. marginale) and Babesia canis vogeli (B. canis vogeli) in the blood of dogs. The results revealed that 4/100 (4%) were positive, and a higher infection rate was found in males (75%), than females (25%). The phylogenetic analysis for the major surface protein 4 (msp4) gene in this study was compared with amplicons separate from other reported isolates with alignment by identity 100% with cattle and camels from Egypt, and the phylogenetic analysis for the B. canis vogeli small subunit ribosomal RNA (SSU rRNA) gene in this study identified identity by 99.89% with dogs from Egypt. This report is considered the first report in southern Egypt about A. marginale in dogs based on the sequence analysis of the msp4 gene, providing new data for the classification and identification of A. marginale in dogs compared to A. marginale isolated from other animals in southern Egypt.

Background: The coronavirus disease known as COVID-19 (2019) pandemic may increase the likelihood of psychological symptoms that can reach the level of psychiatric disorders. Aim: We aimed to study psychiatric morbidity in patients with COVID-19 concerning gender differences and disease severity in the acute phase of infection and after 6 months. Methods: This is a multicenter follow-up study registered in ClinicalTrials.gov (NCT04459403). Patients were recruited consecutively from three quarantine hospitals in Egypt. Data were collected through a questionnaire built using Google Forms including the Arabic versions of General Health Questionnaire (GHQ-12), Beck Depression Inventory (BDI), and Taylor Manifest Anxiety Scale (TMAS). Depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms were assessed after 6 months. Results: The study questionnaire was offered to 400 patients and 199 patients agreed to fill it. BDI and TAMS were higher in mild than moderate and severe COVID-19 (14, 8, 8, P-value = 0.009, 17, 13.5, 14, P-value = 0.04, respectively). Females showed a higher prevalence of depression, anxiety, sleep problems, and insomnia due to anxiety than males. Education level, marital status, previous psychiatric illness, and severity of COVID-19 independently affected depression. Marital status, family history of psychiatric illness, and chronic medical illness independently affected anxiety. On 6-month follow-up, BDI significantly decreased in males but not females. TMAS showed no significant changes, but the severity of anxiety was still higher in females. PTSD was more frequent in females (26 (37.1%) versus 4 (9.5%), respectively, P-value = 0.02). Conclusion: The prevalence and severity of depression and anxiety were higher in females than male participants, suggesting that females are more affected by the COVID-19 pandemic.

Introduction: Avian coccidiosis presents a significant challenge to the poultry industry in Egypt, highlighting the urgent need for validating new drug targets offering promising prospects for the development of advanced anticoccidials. Although numerous reports highlight the activity of lactoferrin (LF) against various microorganisms, its potential against Eimeria has not been explored. The present study evaluated the potential anticoccidial effect of LF and diclazuril in broiler chickens experimentally infected with Eimeria tenella. Methods: A total of 100 one-day-old broiler chicks were divided into five equal groups (20 each) as follows: Group 1 (G1) served as the normal healthy control group, Group 2 (G2) consisted of chickens infected with 1 × 105 sporulated E. tenella oocysts at 14 days of age, Group 3 (G3) comprised infected chickens treated with diclazuril (0.5 mL/L in drinking water) for 3 days successively, Group 4 (G4) included infected chickens treated with LF (at a dose of 250 mg/kg of diet) from one day of age until the end of the study, and Group 5 (G5) comprised infected chickens treated with both LF and diclazuril. Results: The positive control group (G2) experienced significant reductions in body weight (BW), BW gain, serum glucose, lipase, amylase, total antioxidant capacity, several hematological indices, and total proteins, along with alterations in various antioxidant enzymes. Conversely, serum levels of aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphatases (ALP), urea, creatinine, nitric oxide, mean corpuscular volume (MCV), White blood cells (WBCs), heterophils, alpha 2, beta 1, and liver contents of malondialdehyde were elevated in this group. Moreover, higher oocyst counts and lesion scores, along with histopathological alterations, were observed in G2. Remarkably, treatment with diclazuril and/or LF demonstrated potent antioxidant and anticoccidial effects, resulting in reduced shedding of oocysts, lesion scores, and lymphocytic infiltrates in the cecum. Additionally, these treatments improved the antioxidant and immune systems in chickens and restored all histopathological changes reported in the infected non-treated group (G2). Conclusion: This study offers novel perspectives on the potential anticoccidial effects of the combination of LF and diclazuril in broiler chickens infected with E. tenella, highlighting the potential synergistic actions of LF in treating poultry coccidiosis.

Introduction: Achieving integration in medical curricula without redundancy in basic medical sciences disciplines is a substantial challenge. Introducing co-teaching in such curricula with active inter-disciplinary participation is believed to best utilize the teaching and learning time for instructors and students, to motivate the students, and to provide a more robust base for bridging the gap between basic and clinical medical sciences in medical schools. Additionally, including more than one student-centered activity in one session is expected to increase the students' involvement and improve the retention of knowledge. Our study aims at minimizing redundancy and improving the students' motivation in learning the topic "insulin-glucose regulation" during the Endocrine and Metabolism module taught to year three students at Galala University, Faculty of Medicine in Egypt. Methods: The authors designed a 3-hr co-teaching integrated session with 3 basic medical sciences aimed to explain the clinical terms including online accessed pre/post-tests, small student groups-created pre/post-session MCQ, with co-sharing of students in the introduction of scientific materials. Results: The students' scores in the post-test showed that they gained more knowledge compared to before. Interestingly, there was only an improvement in the students' performance in generating questions before and after the session, as well as in the integrated question in the end-of-semester exam, we suggest implementing this approach in other topics and modules in medical schools. It would also be favorable to follow up with the students taught using this approach and those taught differently to assess the effectiveness of this approach in a controlled manner. Conclusion: Integrated sessions effectively increase student awareness of medical concepts and reduce redundancy in basic medical sciences. This approach exposes students to a more comprehensive understanding of the subject matter, improving their comprehension and retention. It is a valuable method for educators and instructors seeking to enhance their students' learning experience in the field of medical sciences. [ABSTRACT FROM AUTHOR]

Image semantic segmentation using deep learning algorithms plays a vital role in identifying different rock-forming minerals. In this paper, we employ the U-net model for its architecture that guarantees precise localization and efficient data utilization. We implement this deep learning model across two distinct datasets: (1) the first dataset from the ALEX Streckeisen website, and (2) the second dataset from the Gabal Nikeiba area, South Eastern Desert of Egypt. Our model exhibits excellent performance in both datasets, with an average accuracy of precision at 0.89 and 0.83, recall at 0.80 and 0.78, and F1 score at 0.82 and 0.79, respectively, helping in identifying and detecting rock-forming minerals in thin-section images. The model's most exceptional performance is clearly in eleven different basement rock-forming minerals with precision up to 0.89, recall at 0.80, and F1 score at 0.82 on average. This study is significant as it represents the key to identifying and detecting minerals in the thin sections of rock samples in Egypt and the Arabian–Nubian Shield as a whole. By significantly reducing analysis time and improving accuracy compared to manual methods, it revolutionizes geological research and resource exploration in the region. [ABSTRACT FROM AUTHOR]
