The purpose of this study was to investigate the influence of cognitive training (CT) using mobile applications on attentional control and impulsivity among pre-service teachers. Pre-service teachers were divided into two groups: experimental (n=25) and control (n=14) groups, they were selected from a large sample (n=718). Over 28 sessions, the training group engaged in CT tasks (the tower of Hanoi [TOH] and simple reaction time [SRT]), whereas the control group did not participate in training sessions or understand the main goal of the study. In the criterion tasks (matching familiar figures and numerical Stroop), all participants were pre- and post-tested. CT using mobile applications helps us see how the trained group's attentional control and impulsivity had influenced. we also observed the progress of trained group as measured by number of moves or time for TOH, and reaction time (RT) for SRT. Other effects were observed in comparison to a control group that underwent no training. There were changes in impulsivity in post-test in favor of training group according to number of moves, and time component of matching familiar figures test. Corresponding to attentional control, the finding indicated that there were changes in (number and size) RT component in post-test in favor of training group.

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.

This study aimed to assess the current water quality status across various regions within the Fayoum depression by examining water canals, drains, and potential contaminants impacting public health and the local ecosystem. Additionally, an adsorption treatability investigation was conducted on various antibiotics identified during the assessment. Fifteen sampling points were selected across the Fayoum depression, covering surface water bodies and agricultural drainage systems during both winter and summer seasons. Physico-chemical, microbiological, and antibiotic analyses were performed on collected water samples. The water quality parameters investigated included pH, electrical conductivity, total dissolved solids (TDS), total coliforms, fecal coliforms, and concentrations of antibiotics such as ciprofloxacin and tetracycline. The findings revealed significant variations in water quality parameters among different water sources, categorizing them into three types: irrigation canals, polluted canals, and drains. High contamination levels were observed in certain water canals and drains due to untreated sewage and agricultural drainage discharge. Notably, elevated TDS levels (exceeding 1200 mg/L), microbial indicators count (with total coliforms reaching up to 2.3 × 106 CFU/100 mL), and antibiotics (with concentrations of ciprofloxacin and tetracycline exceeding 4.6 µg/L) were detected. To mitigate antibiotic contamination, a Phyto-adsorption treatability study using magnetite nanoparticles prepared with Phragmites australis plant extract demonstrated promising results, achieving complete removal of high antibiotic concentrations with an adsorption capacity of up to 67 mg/g. This study provides updated insights into water quality in the Fayoum depression and proposes a novel approach for addressing antibiotic contamination, potentially safeguarding human and environmental health.

Background: In light of the ongoing monkeypox (MPOX) epidemic, healthcare workers (HCWs) have been in contact with various diseases. Therefore, they should take appropriate preventive and control measures to maintain their health. This study assessed Egyptian HCWs' intentions to take MPOX vaccines. Methods: A cross-sectional survey was conducted using social media platforms between September 27 and November 4, 2022. An anonymous online survey using the 5C scale was conducted using convenience and snowball sampling methods to assess the five psychological antecedents of vaccination (i.e., confidence, constraints, complacency, calculation, and collective responsibility). Results: A total of 399 HCWs with a mean age of 32.6 ± 5.7 participated in this study. Of them, 89.7% were female. The five C psychological antecedents of vaccination were as follows: 55.9% were confident about vaccination, 50.6% were complacent, 56.6% experienced constraints, 60.7% calculated the risk and benefit, and 58.4% had collective responsibility. Multivariate analysis showed that high income level and having information about MPOX were significant predictors of confidence in the MPOX vaccines (adjusted odds ratio ((AOR) = 4.19, 95% CI (1.12– 15.59), P = 0.032). Participants aged 31–45 years and 19–30 years showed significant association (AOR = 2.46, 95% CI (0.85–7.15), P = 0.096) and (AOR = 4.19, 95% CI (1.39–12.64), P = 0.011), respectively. Having an idea about the MPOX vaccines significantly predicted the complacency domain (AOR = 3.77, 95%CI (1.47–9.65, P = 0.006). Moreover, precollege/undergraduate education and having an idea about MPOX vaccination were significant predictors of the constraint domain (AOR = 1.81.95% CI (1.09–2.99, P = 0.020), (AOR = 2.70, 95% CI (1.05–6.95, P = 0.038), respectively). Female sex, having a diploma, postgraduate studies, and having an idea about MPOX vaccine significantly predicted calculation domain (AOR = 2.06, 95% CI (1.05–4.04, P = 0.035), (AOR = 3.98,95% CI (1.33–11.87, P = 0.013), (AOR = 2.02, 95% CI (1.25–3.26, P = 0.004) & (AOR = 2.75. 95% CI (1.05–7.18, P = 0.039), respectively. The only significant predictor of collective responsibility was having a diploma and postgraduate studies (AOR = 3.44, 95% CI (1.21–9.78, P = 0.020), (AOR = 1.90,95% CI (1.17–3.09, P = 0.009). Conclusions: Efforts to control MPOX should focus on promoting protective measures such as the vaccination of HCWs as well as raising their awareness about the updated information regarding the virus and the approved vaccines.

Background: There are many challenges that entail caring for an individual with dementia, affecting not only the individual with the condition but also their caregivers. This can lead to increased burden, frustration, and depression among those taking care of them. A research gap exists concerning the care of people with dementia in Egypt, particularly regarding the mental health of caregivers. Limited studies have been conducted in Egypt, particularly focusing on the mental health of caregivers. This lack highlights the need to understand the prevalence and impact of caregiver burden in this population. Objectives: The research aimed to evaluate the burden of dementia, levels of depression, and anxiety among family caregivers of individuals with dementia. Methods: A cross-sectional study was conducted at a geriatric unit clinic of a psychiatric hospital in Cairo University, Egypt. Caregiver burden, anxiety, and depression were assessed using questionnaires. These questionnaires included the Zarit Burden Interview (ZBI), Generalized Anxiety Disorder scale (GAD-7), and Patient Health Questionnaire-9 (PHQ-9), together with demographic data on the patients and caregivers. Results: The majority of the 141 participants (73% (n = 103)) were female, mostly daughters, with an average age of 40 years. Approximately 50% (n = 71) of the subjects exhibited mild to moderate burden, whereas 30% (n = 43) showed moderate to severe burden. About 31% (n = 44) of the subjects exhibited symptoms of moderate depression, whereas 9% (n = 13) had symptoms of severe depression. Furthermore, almost 43% (n = 60) of caregivers exhibited a moderate level of anxiety. Furthermore, a significant association was seen between caregiver burden and the presence of anxiety and depression. Conclusion: This study showed a substantial burden in providing care, elevated levels of despair, and anxiety among caregivers of PWD. The findings highlight how important it is to develop targeted therapies and support systems in order to lessen the load on caregivers, advance their mental health, and improve overall care for both caregivers and their patients in Egypt. Policy-makers should prioritize investing in dementia-related support systems and services to empower caregivers and improve the quality of life for both caregivers and their patients.

Background: Accurate staging is necessary for predicting hepatocellular carcinoma (HCC) prognosis and guiding patient management. The Barcelona Clinic Liver Cancer (BCLC) staging system has limitations due to heterogeneity observed among patients in BCLC stages B and C. In contrast, the Hong Kong Liver Cancer (HKLC) staging system offers more aggressive treatment strategies. Aim: To compare the prognostic performance of HKLC and BCLC staging systems in Egyptian patients with HCC. Methods: We conducted a retrospective study at the National Liver Institute, Menoufia University, Egypt, on 1015 HCC patients. Data was collected from patients' medical records over 10 years (from 2008 to 2018). The BCLC and HKLC stages were identified, and Kaplan-Meier survival analysis was used to compare patients' overall survival rates within each staging system. Additionally, we evaluated the comparative prognostic performance of the two staging systems. Results: Hepatitis C was identified as the underlying etiology in 799 patients (78.7%), hepatitis B in 12 patients (1.2%), and non-viral causes in 204 patients (20.1%). The survival analysis demonstrated significant differences across the various stages within both the BCLC and HKLC systems. The receiver operating characteristic (ROC) curves indicated a marginally superior performance of the HKLC system in predicting survival at 1, 2, and 3 years compared to the BCLC system. Furthermore, the HKLC staging provided a slightly enhanced prognostic capability, particularly for patients classified under BCLC stages B and C, suggesting a potential survival benefit. Conclusion: HKLC classification had a slightly better prognostic performance than BCLC staging system and may offer a survival advantage for certain patients with HCC in BCLC stage B and C HCC cases.

The present study examines the discourse of a number of Short Messaging Service (SMS). The selected data is analyzed according to the lexico-grammatical choices reflected in the interpersonal metafunction. Results are, then, interpreted for the purpose of deciding how service providers use language to convince a large number of customers of their digital products. Such accomplishment is conditioned by how much they succeed in persuading their audience that they are capable of providing them useful products and how these products, in turn, meet their communicative demands. The study assure that the selection of the lexico-grammatical tools is crucial in enabling senders to perform a number of functions such as constructing social relations, exercising power or maintaining solidarity with the receivers.

The study explores gender differences and the role of the ideological background in portraying the roles of the males and the females. Socio-economic statuses affect the description of gender differences and this is proclaimed within the analysis of a recent phenomenon of poor quality street songs. The study represents a detailed description of male and female relationship, so as to spot the light on the literary and societal implications of this newly propagated genre. The study analyses two common songs spreading among commoners distorting the woman's image predefined in the Egyptian culture. Negative cultural and societal conceptions are explicitly mentioned about the relation between males and females.

The study investigates the representation of male and female gender identities in Egyptian street songs called "Mahraganat." The study discusses the issue with reference to two common songs spreading among young commoners. Since the songs are written by writers who descend from low-standard social group, the analysis exhibits both cultural and societal notions related to how males and females are portrayed in such kind of music. This study attempts to describe how males describe their social group in comparison to the social group to which the women belong. It, thus, constructs the social identity of males and females through the lyrics of this new genre of music. The findings from such an analysis answer the question about such genre within its social context and the ideologies by which it is dominated reflecting the discursive construction representation of gender and sexual identity.

Amaranthus viridis (AV) is an invasive weed designated for natural antioxidants. In the current endeavor, A. viridis aerial parts and soil samples were collected from six districts of Fayoum depression (FD), Egypt and were subjected to chemical and biological examination. Where, the organic extracts of the aerial parts of the six distinctive samples (AV1-AV6), were subjected to LC-HRESI-MS-assisted chemical profiling. Multivariate analysis of MS data revealed good clustering of A. viridis collected from three sites (1, 2 and 6) and empowered the hypothesis of chemical composition analogy among extracts AV1, AV2 and AV6. On the other hand, extracts AV3, AV4 and AV5 were not resemblant to each other and were apart from AV1, AV2 and AV6. Similarly, multivariate analysis of physico-chemical properties of A. viridis -associated soil samples showed good clustering of the same three sites (1, 2 and 6). The total phenolics contents (TPC) and total antioxidant capacity (TAC) were promising in all extracts, and they could be arranged in the order of AV6 ˃ AV2 ˃ AV5 ˃ AV3 ˃ AV4 ˃ AV1. Moreover, the uniqueness of AV2, AV3 and AV4 extracts lies in guttiferic acid and the high content of alkaloids that granted the privilege of cytotoxicity toward human liver cancer cell line (HepG2) and human metastatic breast cancer cell line (MDA-MB-231). Regarding the antimicrobial activity, AV1 and AV6 showed the highest antibacterial activity against S. aureus meanwhile AV2, AV3 and AV5 depicted the highest values in case of S. typhi and E. coli. Also, the study revealed that AV1, AV4, and AV6 reflects their prodigious minimum inhibitory concentration (MIC) values against E. coli, S. aureus, and S. typhi. In terms of antifungal activity, AV6 extract recorded as the most inhibition performance against A. flavus and A. niger , whereas AV2 and AV5 inhibited C. albicans the least. According to biofilm activity, AV4 and AV5 were superior, remarkably against E. coli and B. subtilis respectively. Interestingly, the AV6 extract performed exceptionally well as an antibiofilm agent against P. aeruginosa. The potency of some extracts rather than others may rely on possible relationships between soil physicochemical characteristics and chemical composition of A. viridis which contributed to the observed biological properties. Such factors should be taken into consideration in assessing quality control of medicinal plants. [Display omitted] • Amaranthus viridis from six locations in Fayoum, Egypt was chemically and biologically investigated. • Multivariate analysis of MS data revealed good clustering of A. viridis collected from three sites (1, 2 and 6) in terms of chemical composition. • All extracts showed good total phenolics content and total antioxidant activity. • AV2, AV3 and AV4 extracts displayed mild cytotoxicity against human liver (HepG2) and human metastatic breast (MDA-MB-231) cancer cell lines. • AV6 showed potent antibiofilm activity against Pseudomonas aeruginosa , and antifungal activity against Aspergillus flavus and Aspergillus niger.

Background: Within the NICU, there is a delicate equilibrium between providing assistance to parents by nurses and prioritising family-centred care (FCC). The FCC assumes the role of a mediator, effectively conveying compassion. The intricate dynamics between FCC, parental nurse support, and parental stress in neonatal intensive care units (NICUs) necessitate comprehensive investigation. Objective: This study examines the mediating effect of FCC on the relationship between parental nurse support and parental stress in NICUs. Methods: This cross-sectional observational study used convenience sampling to select 223 parents (202 mothers) from Mansoura City hospitals in Egypt. Data were collected using the Nurse Parent Support Tool (NPST), Family-Centered Care Self-Assessment Tool (FCCS-NICU), and the Parental Stressor Scale: NICU (PSS: NICU). Mediation analysis was used to examine the relationships between variables. Results: Nurse support was positively associated with FCC (β = 0.81, p < 0.001) and negatively related to parental stress (β=-1.156, p < 0.001). FCC was found to reduce parental stress (β=-0.18, p < 0.001). Mediation analysis confirmed that FCC partially mediated the relationship between nurse support and parental stress (indirect effect β = 0.145, 95% CI: 0.055–1.007). Conclusions: This study highlights a significant association in the mediating role of FCC between nurse support and parental stress. Strengthening FCC practices can be an effective strategy for nurses to support parents and alleviate their stress in NICU settings. Implications to practice: NICUs should implement FCC-oriented training for nurses, foster a culture that supports FCC principles, and develop policies to establish FCC as a cornerstone of neonatal care.

Background: Schizophrenia is a prevalent psychiatric disorder that affects 1% of the global population. Schizophrenia frequently begins in late adolescence or early adulthood, causing significant educational, social, and economic costs for people and society. Functional neuroimaging research on schizophrenia physiopathology has been beneficial. Arterial spin labelling (ASL) is one of functional magnetic resonance imaging (fMRI) technologies that assess brain function without radiation. ASL uses magnetic resonance (MR) imaging to quantify tissue-level brain perfusion non-invasively. Arterial spin labelling (ASL) is one of the functional magnetic resonance imaging (fMRI) technologies that assess the brain function without radiation hazards. ASL uses magnetic resonance (MR) imaging to quantify tissue-level brain perfusion non-invasively. Many publications were performed on role of different advanced MRI techniques in schizophrenia, but our study insisted on the added value of combined ASL and MRS over the conventional MRI in schizophrenic Egyptian population sample. Aim of the work: The purpose of this work was to evaluate the added value of combined ASL-perfusion MRI and MRS in schizophrenic patients. Methods: This prospective case–control study was carried out on two groups: First group was 30 patients who were diagnosed clinically as schizophrenic patients, and second group was 20 healthy volunteers as a control group for comparison in the period from August 2021 till July 2022. Results: The majority of newly diagnosed cases had significant higher positive symptoms than chronic cases. According to arterial spin labelling (ASL) data, rCBF was noticed to be reduced in anterior cingulate, frontal lobe, and parietal lobe of both patients' subgroups but more significant in chronically ill patients. Convergent results of decreased rCBF were also found in the parietal lobe and occipital lobe. Magnetic resonance spectroscopic analysis showed that NAA was decreased in the anterior cingulate cortex, thalami and basal ganglia of the newly diagnosed cases more than chronic cases. The ASL-MRI perfusion accurately detected the hypo-perfusion of different brain regions with sensitivity 100%, specificity 66.67%, positive predictive value 96.43%, negative predictive value 100%, and accuracy 96.67%, while MR spectroscopy showed sensitivity 100%, specificity 33.33%, positive predictive value 93.10%, negative predictive value 100%, and accuracy 93.33% in evaluation of changes of brain metabolites. Conclusion: ASL is a promising functional MRI technique that can produce together with MRS quantitative information about the metabolites of different brain regions. The ASL-MRI appears as a reliable non-invasive technique to measure cerebral blood flow and identify decreased rCBF without any contrast administration, and it could be repeatable which helps in early diagnosis as well as follow-up of the progression of the disease.

Equine piroplasmosis is not fully understood regarding pathogenicity, prophylaxis, host immune response expression, and specific vectors. Accurately identifying the parasite vector is crucial for developing an effective control plan for a particular infection. This study focused on morphologically identifying two Hyalomma species (H. anatolicum and H. marginatum) and one Rhipicephalus annulatus (R. annulatus) at the species level. The identification process was followed by phylogenetic analysis using the neighbor-joining method based on the cytochrome oxidase subunit 1 (COXI) gene as a specific vector for Theileria equi (T. equi) in horses. T. equi was diagnosed morphologically and molecularly from infected blood samples and crushed tick species using conventional PCR. Subsequently, phylogenetic analysis based on the amplification of the 18 S rRNA gene was conducted. The obtained sequence data were evaluated and registered in GenBank under accession numbers OR064161, OR067911, OR187727, and OR068139, representing the three tick species and the isolated T. equi, respectively. The study demonstrated that T. equi infection leads to immune system suppression by significantly increasing the levels of oxidative stress markers (CAT, GPx, MDA, and SOD) (P ≤ 0.0001), with this elevation being directly proportional to parasitemia levels in infected blood cells. Furthermore, a correlation was observed between parasitemia levels and the expression of immune response infection genes (IFN-gamma, TGF-β1, and IL-1β cytokines) in infected horses compared to non-infected equine. Common macroscopic symptoms indicating T. equi infection in horses include intermittent fever, enlarged lymph nodes (LN), and tick infestation. [ABSTRACT FROM AUTHOR]

Background: Currently, tap water consumption is not highly preferred in Egypt and around the world. People prefer to consume bottled water because they believe that it is much safer and tastes better than tap water. Unfortunately, this preference can create an economic burden for many people, especially in developing countries. Clay pots can be used to provide cool, alkaline drinking water because of their porous micro-texture, which traps pollutants. This study aimed to investigate the use of clay pots to store tap water and its impact on the requirements for drinking water quality. This is done with the intent to decrease the need for bottled water as a means of offering a more sustainable and economical option. Methods: In this study, the efficiency of clay pots as sustainable storage containers for drinking water was tested by measuring physicochemical parameters (pH, TDS, EC, turbidity, DO, ammonia, chloride, total hardness, Ca hardness, Mg hardness, chlorine, Zn, and CaCO3) and biological parameters (TPC and Legionella). Results: After 7 days of storage, the quality of the water stored in clay pots met the standards set by the Egyptian law with a significant difference (p < 0.05) before and after the storage of water It was found that the dissolved oxygen increased from 6.17 ppm to 7.52 ppm after 7 days. As for total hardness, it declined from 195 to 178 ppm. There was also a significant drop in terms of TDS from 338 to 275 ppm. Furthermore, clay pots effectively filtered out both total viable bacteria and Legionella. Conclusion: This study proved the efficiency of using these containers with respect to some indicator values for tap water and tank water analysis. Clay pots are an excellent, cost-effective, and sustainable alternative for storing water. [ABSTRACT FROM AUTHOR]

In a world where asylum and migration have become major concerns for countries of transit and destination, political neutrality seems to be demanded from humanitarian workers. But under the pressures of workload, limited funds, and complex settings, these actors deviate from expectations and practice extra‐legal authority of a unique political nature. When handling asylum cases, these agents take crucial decisions that decisively impact the lives of asylum seekers. In legally fragile transit points where the rule of law faces challenges and where asylum seekers come seeking further resettlement in European countries, rejected applicants face risky fates of deportation, jail, violence, or death. In turn, humanitarian caseworkers pushed by workloads, purse strings, emotional burnout, and compassion fatigue, flatten the sufferings of their applicants, balance, and rank them. Caseworkers have to rank sufferings and decide who may eventually survive and who may simply be left to a risky unknown. In Agambian terms, this extralegal authority draws the lines, creates a zone of exception and throws rejected applicants into the realm of "Bare Life" where they become "Homo Sacer," whose life is worthless. Using Lipsky's theorization of street‐level bureaucrats and in‐depth interviews, the paper tackles these crucial issues by interviewing caseworkers from a variety of international organizations operating in the transit point of Egypt. These caseworkers are responsible for conducting different roles in the Refugee Status Determination process. [ABSTRACT FROM AUTHOR]

Background: Addressing microbial resistance urgently calls for alternative treatment options. This study investigates the impact of a bimetallic formulation containing colistin, silver, and copper oxide on a pandrug-resistant, highly virulent Pseudomonas aeruginosa (P. aeruginosa) isolate from a cancer patient at the National Cancer Institute, Cairo University, Egypt. Methods: Silver nanoparticles (Ag NPs), copper oxide nanoparticles (CuO NPs), and bimetallic silver-copper oxide nanoparticles (Ag-CuO NPs) were synthesized using gamma rays, combined with colistin (Col), and characterized by various analytical methods. The antimicrobial activity of Col-Ag NPs, Col-CuO NPs, and bimetallic Col-Ag-CuO NPs against P. aeruginosa was evaluated using the agar well diffusion method, and their minimum inhibitory concentration (MIC) was determined using broth microdilution. Virulence factors such as pyocyanin production, swarming motility, and biofilm formation were assessed before and after treatment with bimetallic Col-Ag-CuO NPs. The in vivo efficacy was evaluated using the Galleria mellonella model, and antibacterial mechanism were examined through membrane leakage assay. Results: The optimal synthesis of Ag NPs occurred at a gamma ray dose of 15.0 kGy, with the highest optical density (OD) of 2.4 at 375 nm. Similarly, CuO NPs had an optimal dose of 15.0 kGy, with an OD of 1.5 at 330 nm. Bimetallic Ag-CuO NPs were most potent at 15.0 kGy, yielding an OD of 1.9 at 425 nm. The MIC of colistin was significantly reduced when combined with nanoparticles: 8 µg/mL for colistin alone, 0.046 µg/mL for Col-Ag NPs, and 0.0117 µg/mL for Col-Ag-CuO NPs. Bimetallic Col-Ag-CuO NPs reduced the MIC four-fold compared to Col-Ag NPs. Increasing the sub-inhibitory concentration of bimetallic nanoparticles from 0.29 × 10-2 to 0.58 × 10-2 µg/mL reduced P. aeruginosa swarming by 32–64% and twitching motility by 34–97%. At these concentrations, pyocyanin production decreased by 39–58%, and biofilm formation was inhibited by 33–48%. The nanoparticles were non-toxic to Galleria mellonella, showing 100% survival by day 3, similar to the saline-treated group. Conclusions: The synthesis of bimetallic Ag-CuO NPs conjugated with colistin presents a promising alternative treatment for combating the challenging P. aeruginosa pathogen in hospital settings. Further research is needed to explore and elucidate the mechanisms underlying the inhibitory effects of colistin-bimetallic Ag-CuO NPs on microbial persistence and dissemination.

During the Late Precambrian, the North Eastern Desert of Egypt underwent significant crustal evolution in a tectonic environment characterized by strong extension. The Neoproterozoic alkali feldspar granite found in the Homret El Gergab area is a part of the Arabian Nubian Shield and hosts significant rare metal mineralization, including thorite, uranothorite, columbite, zircon, monazite, and xenotime, as well as pyrite, rutile, and ilmenite. The geochemical characteristics of the investigated granite reveal highly fractionated peraluminous, calc–alkaline affinity, A-type granite, and post-collision geochemical signatures, which are emplaced under an extensional regime of within-plate environments. It has elevated concentrations of Rb, Zr, Ba, Y, Nb, Th, and U. The zircon saturation temperature ranges from 753 °C to 766 °C. The formation of alkali feldspar rare metal granite was affected by extreme fractionation and fluid interactions at shallow crustal levels. The continental crust underwent extension, causing the mantle and crust to rise, stretch, and become thinner. This process allows basaltic magma from the mantle to be injected into the continental crust. Heat and volatiles were transferred from these basaltic bodies to the lower continental crust. This process enriched and partially melted the materials in the lower crust. The intrusion of basaltic magma from the mantle into the lower crust led to the formation of A-type granite.

Background: Cooperative learning strategies like team-based learning have a great effect on the learning process. It increase problem solving skill, learning motivation and academic achievement and allows interaction between students and increases their engagement. The aim of the study was to evaluate the effect of implementing team-based learning strategy regarding gastrostomy feeding on group engagement for pediatric nursing students’ performance. Research design: True experimental research design was utilized. Subjects and setting: 140 pediatric nursing students in third year, Faculty of Nursing, Tanta University. Four tools were used to collect data: Tool I: Structured Questionnaire of pediatric nursing Students’ Knowledge regarding Gastrostomy Feeding. Tool II: Gastrostomy Feeding Observational Checklist. Tool III Pediatric Nursing Students' Group Engagement Questionnaire. Tool IV: Team-Based Learning Feedback Questionnaire. The results: The total scores of pediatric nursing students' knowledge, practices and group engagement were improved immediately and two weeks after the implementation of team-based learning strategy. The study concluded that using the team-based learning strategy in the pediatric nursing course has a beneficial effect on enhancing the knowledge, critical thinking, clinical performance, and engagement of the students. The study recommended that the curriculum of the pediatric nursing department should contain a team-based learning strategy as an engaging teaching technique. [ABSTRACT FROM AUTHOR]

Background Toxicologists manage poisoning by preventing, detecting, and treating it, which requires continuous data collection and analysis of toxicological hazards. Aim of the work The study aims to report and compare the pattern and outcome of acute toxicological cases admitted to Sohag University Hospitals during the COVID-19 lockdown (2020–2021) with the year before (2019) and the year after (2022). Methods This comparative study reviewed the sociodemographic and clinical data in the medical records. The study showed that Sohag University Hospitals received 670 toxicological cases between 2019 and 2022; 105 cases in 2019, 347 cases in 2020–2021, and 218 cases in 2022. Results Most of patients were below seven years with no sex differences. Accidental poisoning was the most frequent toxicity. The oral route was the most common in the three studied periods. During the lockdown, metal phosphide was the most frequent (19.0%), while therapeutic agents were the most reported after the lockdown (23.9%). The delay time showed a significant difference between the studied periods (p -value < 0.001). In the three studied periods, complete recovery was achieved in more than 70% of cases; however, the mortality rate and the rate of complications during the lockdown period (10.4% and 9.5%, respectively) were almost twice those of the year before and the year after the pandemic with significant odds ratio of mortality during pandemic (OR) 0.07 CI 95% (0.02, 0.11). Conclusion The pandemic had a bad impact on outcomes as showed the highest percentage of mortality compared to before and after COVID-19 periods. [ABSTRACT FROM AUTHOR]

The River Nile is the artery of Egypt, as it presents more than 96% of the municipal, industrial, and irrigation necessities of Egypt. This study was dedicated to providing data about the effect of pollution at six stations on the River Nile at the Rosetta branch during the period from August 2019 to April 2020, using heavy metals analysis and zooplankton as biological indicators. It was found that the average of heavy metals concentration follows the descending order Al > Fe > Mn > Zn > Ni > Co. Most of the heavy metals recorded its highest values at El-Rahawy station. Zooplankton community was represented by 32 species in addition to 4 Meroplanktons. Five groups of zooplankton were recorded, viz. Rotifera (1717 org./L), Protozoa (552 org./L), Cladocera (54 org./L), Nematoda (46 org./L), and other Meroplankton (44 org./L), dominated by Rotifera followed by Protozoa, Cladocera, Nematoda, and other Meroplanktons contributing 71%, 23%, 2%, 2%, and 2%, respectively. The highest average density of total zooplankton was recorded during spring while the lowest was recorded during summer. The highest similarity of (79.12%) was observed between (Site 1) and (Site 5). Almost all diversity indices were conducted and showed its highest values in site 6. The principal component analysis conducted between heavy metals, and zooplankton showed a significant negative correlation was shown for the dominant zooplankton with the heavy metals except with cobalt. Nematoda and the rotifer Brachionus angularis recorded a positive correlation with heavy metals except cobalt. [ABSTRACT FROM AUTHOR]

A crucial first step in preventing the introduction and spread of harmful microorganisms in poultry farms is biosecurity. The objectives of this investigation were to assess biosecurity measures and the prevalence of different E. coli species in commercial chicken farms in Sharkia province, Egypt. Sensitivity of E. coli strains was identified, and their susceptibility to antibiotics and disinfection was evaluated as well. Four farms provided 21 samples each, for a total of 84 samples. Three samples of each were collected for water, feed, litter, cloaca, wall, hand, and foot boots. All the studied farms obtained a "poor biosecurity" grade, meaning that their overall biosecurity score, which is comprised of 40% external and 36.54% internal biosecurity, was less than 50%. Escherichia coli species were found in 79.76% of the samples. It was isolated from water, feed, litter, cloaca, walls, hands, and foot boots with percentages of 91.6; 83.3; 91.6; 100; 58.3; 58.3 and 75%, respectively. Biosecurity level had significant negative correlations with the isolated E. coil species. Escherichia coli O119 was the most common serotype in litter and the cloaca, while E. coli O1 was the most prevalent serotype in walls and hands. Additionally, serotypes for E. coli O26, O159, O128 and O78 were included. According to the patterns of antibiotic sensitivity, amikacin, nitrofurantoin, gentamycin, and levofloxacin showed intermediate sensitivity, whereas E. coli O119 bacteria were highly sensitive to ciprofloxacin. In the absence and presence of organic matter, Virocid, Cid 2000 and finally Virkon S were the most efficient against E. coli O119. According to this study, there were differences in the investigated farms' biosecurity levels in relation to the occurrence of Escherichia coli. To reduce the introduction and persistence of E. coli in poultry farms, several biosecurity practices and management, including stringent cleaning and disinfection measures should be applied.

Inflammation is a part of the body's intricate biological reaction to noxious stimuli and defensive reactions. So, the aim of this investigation was to study the anti-inflammatory activity of exopolysaccharide (EPSSM) using carrageenan-induced paw edema in rats. A halophilic bacterial strain was isolated from marine sediments in the Red Sea in Egypt. The isolate has been visually and physiologically recognized, as well as by analyzing its 16S rRNA gene, which confirms Kocuria sp. clone Asker4. This particular isolate can be referenced using the accession number OL798051.1. EPSSM was subjected to purification and fractionation by a DEAE-cellulose column. Preliminary chemical analysis of EPSSM indicated that the monosaccharides were fructose, glucuronic acid, and xylose, with 2.0, 0.5, and 1.0, respectively. The antioxidant potential of EPSSM was investigated, and it was discovered that the level of activity increased independently of the concentrations, reaching a maximum threshold of 94.13% at 100 µg/mL of EPSSM for 120 min. Also, EPSSM at 50 mg/kg orally produced a significant anti-inflammatory effect on the carrageenan model at 2, 3, and 4 intervals. The EPSSM intervention resulted in reductions in the levels of catalase and superoxide dismutase enzymes, as well as a decrease in glutathione. Furthermore, the levels of nitric oxide, lipid peroxidation, and reactive oxygen species resulting from carrageenan-induced edema showed a significant reduction subsequent to the administration of EPSSM. Moreover, the findings indicated that the protein expression levels of cyclooxygenase-2 and interleukin-6 were reduced following treatment with EPSSM, resulting in a reduction of paw edema.

Coagulase-negative staphylococci (CoNS) are a group of gram-positive staphylococcal species that naturally inhabit the healthy human skin and mucosa. The clinical impact of CoNS-associated infections has recently been regarded as a challenge for diagnosis and therapeutic options. CoNS-associated infections are primarily caused by bacterial resistance to antibiotics and biofilm formation. As antibiotics are still the most used treatment, this problem will likely persist in the future. The present study aimed to investigate the resistance and virulence of CoNS recovered from various acne lesions and explore their genetic basis. Skin swab samples were collected from participants with acne and healthy skin. All samples underwent conventional culture for the isolation of CoNS, MALDI-TOF confirmation, antibiotic susceptibility, and biofilm formation testing. A total of 85 CoNS isolates were recovered from the samples and preliminarily identified as Staphylococcus epidermidis. Isolates from the acne group (n = 60) showed the highest rates of resistance to penicillin (73%), cefoxitin (63%), clindamycin (53.3%), and erythromycin (48%), followed by levofloxacin (36.7%) and gentamycin (31.7%). The lowest rates of resistance were observed against tetracycline (28.3%), doxycycline (11.7%), and minocycline (8.3%). CoNS isolated from mild, moderate acne and healthy isolates did not show strong biofilm formation, whereas the isolates from the severe cases of the acne group showed strong biofilm formation (76.6%). Four extensively drug-resistant and strong biofilm-forming staphylococcal isolates recovered from patients with severe acne were selected for whole-genome sequencing (WGS), and their genomes were investigated using bioinformatics tools. Three of the sequenced genomes were identified as S. epidermidis; however, isolate 29AM was identified as Staphylococcus warneri, which is a newly emerging pathogen that is not commonly associated with acne and was not detected by MALDI-TOF. All the sequenced strains were multidrug-resistant and carried multiple resistance genes, including blaZ, mecA, tet(K), erm(C), lnuA, vgaA, dfrC, fusB, fosBx1, norA, and vanT, which were found to be located on plasmids and chromosomes. Virulence features were detected in all genomes in the presence of genes involved in adherence and biofilm formation (icaA, icaB, icaC, sdrG, sdrH, atl, ebh, and ebp). Only the S. warneri isolate 29AM contained immune evasion genes (capB, capC, acpXL, and manA), an anti-phagocytosis gene (cdsA), and other unique features. As a result of their potential pathogenicity and antibiotic resistance, CoNS must be monitored as an emerging pathogen associated with acne infections. To the best of our knowledge, this is the first report to isolate, identify, and correlate S. warneri with severe acne infections among Egyptian patients using WGS and bioinformatic analysis.

High-quality animal protein, vitamins B1, B6, and B12, as well as minerals like zinc, selenium, and iron, can all be found in buffalo meat and milk. Organochlorine pesticides (OCPs) have been widely utilized for many years because of their long duration of action, low cost, and toxicity against a variety of pests. Despite being outlawed everywhere, OCPs are still being used illegally. One of the main responsibilities of the food safety and public health sectors is to guarantee the safety and wholesomeness of such food products before they are made available to the public. In order to determine the residual OCP contents in retailed buffalo meat, liver, kidney, milk, and kariesh cheese, this study was conducted. The obtained results in the current investigation revealed the detection of OCPs at 75%, 40%, 25%, 60%, and 80% in the examined buffalo raw milk, kariesh cheese, meat, kidneys, and liver. Different OCPs were detected at variable concentrations; however, such concentrations were within the established permissible limits in Egypt. In conclusion, OCPs are still in use in Egyptian agricultural activities and residual concentrations can be detected in the meat, offal, and dairies. Therefore, it is highly advised to continuously check for OCP residues in foods with both animal and plant origins. Additionally, it is strongly advised that farmers become more aware of the negative consequences of OCPs. [ABSTRACT FROM AUTHOR]

BACKGROUND: Stress and fatigue experienced by lactating employed mothers can affect mothers' and babies' mental and physical health detrimentally. Aerobic exercise is known to control stress and fatigue, but the dosages of the exercises needed to maintain long-term effects are still under investigation. OBJECTIVE: This study aimed to investigate the acute and long-term effects of aerobic exercise on controlling stress and fatigue in lactating, employed mothers. METHODS: This randomized control study involved sixty lactating, employed mothers suffering from stress and fatigue. They were divided into two groups: Group A received five sessions of 30-minute aerobic training on a treadmill per week, in addition to lifestyle modification advice for six weeks. Group B received the same lifestyle routine advice for the same duration without being trained. Assessments of stress and fatigue levels were done before, after 6 weeks, and after 6 months from the baseline assessments using the Perceived Stress Scale (PSS-10) and Fatigue Assessment Scale (FAS), respectively. RESULTS: Post-six-week comparisons within and between both groups showed a significant decline in PSS-10 and FAS in group A compared with group B (p < 0.001); however, after six months of follow-up, there were statistically significant effects within groups only (p < 0.05) and no statistically significant difference between groups at both variables (p > 0.05). CONCLUSION: Aerobic exercises for 6 weeks can induce an acute but not long-term effect on stress and fatigue control in lactating-employed mothers. Future research is needed to tailor the exercise prescription needed to maintain training's long-term benefits. [ABSTRACT FROM AUTHOR]

Background: Interval cancers might be divided into true negative interval cancer where a new lesion is detected that no sign of disease could be detected on previous screening mammogram. For false-negative interval cancers, those missed for overt symptoms and those missed for mild or undetectable ones, this includes interpretive error as benign interval cancer (benign mimics), subtle changes, masked carcinoma or slowly growing or patient factors, such as the dense breast parenchyma. Technical failure interval cancer hampered the reader to discover the abnormality. The aim of this study was to relate the risk factors for the development of the interval breast cancer such as breast density, positive family history of breast cancer in Egyptian population. Highlight the causes of missed breast cancer in order to overcome it in the future radiological interpretation. Methods: A total of 74,546 screening mammographic examinations were performed in the radiology department at specialized breast cancer center in the period between 2015 and 2021 with about 844 pathologically proved malignant cases. Out of the 844 pathologically proven breast cancer cases, 185 breast cancer patients were interval breast cancer having reported normal examination in the previous year, 88 were true interval breast cancer and 97 were missed on mammography and detected later on. The cases were subjected to full-field digital mammogram (FFDM), complementary ultrasound, contrast-enhanced digital mammography (CEDM) and magnetic resonance imaging (MRI) in some cases, and all cases were histopathologically proven by either fine needle aspiration, core needle biopsy (CNB) or open biopsy. Results: The mean age of the patients was 53.5 years (range 36–83 years). The overall breast cancer detection rate was 11 per 1000 women. The 185 interval cancers were present at a rate of 3.8 per 1000 women. True negative interval breast cancers where 88 cancers were not present in retrospect on screening mammograms, 17 cases present with benign findings (benign mimics mass or calcifications) and 80 cancers were missed cancers. Analysis of the cause of missed carcinoma revealed patient-related, tumor-related, or provider-related factors. Tumor factors were the most commonly encountered, accounting for 49.5% (48 cases), then provider factors in 25.8% (25 cases) while the patient factors were the least commonly encountered in 24.7% (24 cases). Recorded positive family history found in about 35% (31cases) of the true interval breast cancers. Conclusions: Although mammography is the standard for detecting early breast cancer, some cancers can be missed due to various causes. Mammographic interpretation must meet high standards to reduce missed cancers. Radiologists should carefully assess screening views and order additional imaging if needed. Palpable lesions and clinical data should be further examined with ultrasound and contrast imaging if necessary. Always compare current images with previous examinations to check for any changes in lesion size. When one pathology is found, search for additional lesions. [ABSTRACT FROM AUTHOR]

Antibiotic resistance of Klebsiella pneumoniae (K. pneumoniae) has become alarming to public health, moreover biofilm production is one of the virulence mechanisms that contributes to antibiotic resistance. Metal oxide nanoparticles are showing promise as antibacterial agents. The purpose of this study was to assess the antibacterial activities and dosage effect of ZnO-NPs against ESBL K. pneumoniae isolates recovered from horses exhibiting respiratory symptoms. The antibiotic sensitivity of ESBL producing K. pneumoniae strains was tested using the Kirby Bauer disc diffusion method, which showed 100% resistance to cefotaxime and erythromycin while resistance to tetracycline, ampicillin, amoxicillin / clavulanic acid, ceftriaxone, ceftazidime, amikacin and ciprofloxacin were 85.7, 71.42, 42.85, 28.57, 28.57, 14.28 and14.28%, respectively. Regarding the biofilm production genes scanning, K. pneumoniae isolates were positive for luxS gene (100%), while only 85.7% of K. pneumoniae were positive for Uge gene and none of them having mrkD gene. ZnO-NPs were tested against a local isolate of ESBL-producing K. pneumoniae for their antibacterial properties. K. pneumoniae had MIC and MBC values of 5ug/ml and 3ug/ml, respectively. In the current study, antibiotic abuse leads to an increase in the population of ESBL-producing K. pneumoniae, posing a concern to public health. ZnO-NPs, a new material, exhibit significant antibacterial activity against hypermucoviscosity K. pneumoniae isolate. [ABSTRACT FROM AUTHOR]

Background: This study aims to assess the epidemiological, clinical, and paraclinical characteristics and survival of childhood with malignant disorders in the pediatrics department, menoufia University Hospital. Methods: A retrospective study with clinical and epidemiological data from patients was conducted on 314 children who attended Pediatric Department, Haematology-Oncology Unit, Menoufia University Hospital during the last fifteen years. Results: 314 children were assessed, their ages ranged from 2 months-18 years with mean 5.96±3.79 years. Also, 252 (80.3%) were diagnosed with hematological malignancies, and 62 (19.5%) were diagnosed with solid tumors. Among hematological malignancies, 186 were diagnosed with acute leukemia, 158 (49.7%) with acute lymphoblastic leukemia (ALL), and 28 (8.8%) with acute myeloid leukemia (AML). The most frequent clinical presentations were fever in 95.24% in hematological malignancies vs 48.4% in solid (p<0.001),, pallor in 92.5% in hematological malignancies vs 69.4% in solid (p<0.001), hepatomegaly in 81.3% in hematological malignancies vs 37.1% in solid (p<0.001),, lymphadenopathy in 77.6 % in hematological malignancies vs 24.2% in solid (p<0.001), and splenomegaly in 76.3% of hematological malignancies vs 12.9% in solid (p<0.001),The majority of the patients 64.15% had white blood cells (WBCs) less than 50,000/mm³, while 35.85% had WBCs more or equal to 50,000/mm³ with significant relation with risk stratification (p=0.001). The survivors who finished their treatment course were 31.8% and the recurence patients were 9%. Conclusion: Acute lymphoblastic leukemia is the most frequent childhood hematological neoplasm. Various clinical and laboratory features present at the time of initial diagnosis can predict the likelihood that a patient will remain in remission or not including age: under 1 and over 10 years, gender: male sex, WBCS more than 50,000/mm³ at presentation.

Background and aim: Nocturnal enuresis (NE) is prevalent in children and adolescents and affects their social life later. Therefore, the objective of this study was to ascertain laser acupuncture (LA) therapy's effect on NE in adolescent females. Methods: Sixty adolescent females diagnosed with chronic monosymptomatic nocturnal enuresis (MNE) were randomly divided into two equal groups: The intervention group (received LA and desmopressin) and the control group (received desmopressin only) (n = 30 each). Treatment was delivered and LA was used three times a week for 12 successive weeks. Abdominal ultrasonography and voiding calendar were used to assess bladder capacity and maximum voiding volume (MVV), respectively. The frequency of bed wetness was assessed throughout the trial period in a diary. Results: Statistically significant differences were reported in the intervention group. Bladder capacity significantly increased in the intervention group (LA and desmopressin) than in the control group. Conclusions: The results of this study suggest the beneficial influences of LA on MNE, despite the very poor quality of the literature's available evidence. [ABSTRACT FROM AUTHOR]

Despite the enormous health burden of lacunar stroke, data from low- and middle-income countries on lacunar stroke characteristics and its comparison with that of high-income countries are scarce. Thus, we aimed to investigate and compare the variable characteristics and vascular status in patients from Egypt and Germany suffering lacunar stroke. Two cohorts of lacunar stroke patients from Ain Shams University Hospital, Egypt and Goethe University Hospital Frankfurt, Germany were retrospectively collected between January 2019 and December 2020 and analyzed for demographics, risk factors, mode of presentation, neuroimaging features, treatment protocols and outcomes. MRI showed a different distribution pattern of lacunar strokes between cohorts, detecting posterior circulation lacunar infarctions preponderantly in patients from Egypt and anterior circulation lacunar infarctions preponderantly in patients from Germany. Complementary MR/CT angiography revealed a significantly higher proportion of intracranial and combined intracranial and extracranial arterial stenosis in patients from Egypt than in patients from Germany, suggesting differences in pathological processes. Younger age, higher NIHSS on admission, and posterior circulation lacunar infarction were predictors of Egyptian origin, whereas hypertension was a predictor of German origin. Our results support the idea of clinical and neuroimaging phenotype variations in lacunar stroke, including different sources of lacunar stroke in patients of different populations and geographical regions. This implies that guidelines for management of lacunar stroke might be tailored to these differences accordingly. [ABSTRACT FROM AUTHOR]

Cattle Egret (Bubulcus ibis) is one of the most well-known herons in Egypt. It is called the friend of the farmer because it benefits farmers and helps them get rid of insects and worms. It acts as a reservoir for many diseases. Few researchers have discussed the significance of parasitic diseases that affect this wild bird and may lead to mortalities among the population especially the importance of vital organs such as kidneys. Therefore, this study aimed to spotlight parasitic infection-affected herons in Egypt and consider the risks to this beneficial bird. During this study, 23 Bubulcus ibis were captured after their death from Abou Rewash Giza Governorate, Egypt, during the period from February to September (2022). Renicola species (spp.) and Apharyngostrigea spp. are two important digenean parasites that were recovered from the kidneys, and small intestine of the heron Cattle Egret (Bubulcus ibis) with an infection rate of (17.2%) and (11.8%) respectively. Histopathological techniques were used to assess tissue alterations while light microscopy and molecular assays were used to assess the parasites. The parasites' morphological and morphometrical characteristics, as well as polymerase chain reaction and sequencing assays (mitochondrial sections), were investigated for the first time in Egypt. These parasites were given in-depth illustrations and drawings. The distinctive qualities of the two species were discussed. As the first record from Egypt, the nucleotide sequences discovered in this work have been uploaded into the GenBank database (accession numbers: OR021986 and OQ955829). Microscopically, the renal blood vessels had vasculitis, necrosis, and other degenerative alterations. Further research analyzing the health of various heron spp. and environmental deterioration can help to close information gaps about the interactions between parasites, their hosts, and environmental health.

Background Synthetic cannabinoids SC are now becoming progressively popular among young people worldwide; little is known about their negative effects. Anger, anxiety, hallucinations, and perceptual changes were the most common psychoactive findings. Substance abuse causes cognitive impairment (CI). This study's goal is to raise public awareness about the dangers that synthetic cannabinoid intoxication poses to public health. As well as the magnitude of CI in synthetic cannabinoids in comparison with healthy controls. The study included 30 synthetic cannabinoids SC addicts and 30 healthy people. The Wechsler memory scale (WMS), the Benton visual retention test (BVRT), and Trail Making Test (TMT) A and B were used to assess cognitive functions. Addiction Severity Index (ASI), Structured Clinical Interview for DSM-IV Axis I Disorder (SCID-I), and Structured Clinical Interview for DSM-IV Axis II Disorder (SCID II). Results Using BVRT, (96.7%) of the SC use disorder cases had more impaired performance than controls (0%) (P < 0.001). Almost three quarters of the cases had impaired performance on the trail making tests A and B compared to none of the controls (P < 0.001). Similarly, there was a high statistically significant difference between SC use disorder cases and controls in all domains of the WMS. There was no statistically significant correlation between the cognitive scales (BVRT, WMS and TMT) results in relation to age of SC use patients or duration of use. Conclusions Patients who used synthetic cannabinoids SC were more likely than controls to develop CI, which manifested as impaired visual, auditory, immediate, delayed, and working memory.

BACKGROUND: Chronic mechanical cervical pain (CMCP) is a common disabling problem worldwide, interfering with upper extremities function. However studying the impact of CMCP on shoulder proprioception is still lacking. OBJECTIVE: To investigate the impact of CMCP on shoulder proprioception in young adults compared with normal control (NC) individuals. METHODS: A comparative study was conducted between two groups; 40 patients with CMCP (mean age 32.28 ± 6.586) and 40 age and sex matched NC (mean age 33.43 ± 9.021). The Biodex isokinetic dynamometer was used to assess shoulder active sense of position at 30 ∘ external and internal rotations. The absolute angular error was calculated for the dominant and non-dominant shoulders. RESULTS: The absolute angular error was significantly increased only in the CMCP at both rotation angles for both shoulders, showing a remarkable increase on the dominant shoulder and in the external rotation range compared with NC. CONCLUSIONS: CMCP can significantly impair shoulder proprioception, particularly on the dominant side and in external rotation range. This could emphasize the careful examination of shoulder proprioception for the early detection of shoulders at risk, to eliminate the possibility of shoulder instability and/or injury in young adults with CMCP.

Purpose: Chronic granulomatous disease (CGD) is an inherited primary immunodeficiency disorder of phagocytes, characterized by recurrent fungal and bacterial infections. Our aim is to describe the different clinical presentations, non-infectious auto-inflammatory features, types and sites of infections, and to estimate the mortality among our large cohort. Methods: This is a retrospective study conducted at the Pediatric Department of Cairo University Children's Hospital in Egypt, including cases with a confirmed CGD diagnosis. Results: One hundred seventy-three confirmed CGD patients were included. AR-CGD was diagnosed in 132 patients (76.3%) including 83 patients (48%) with p47phox defect, 44 patients (25.4%) with p22phox defect, and 5 patients (2.9%) with p67phox defect. XL-CGD was diagnosed in 25 patients (14.4%). The most common recorded clinical manifestations were deep-seated abscesses and pneumonia. Gram-negative bacteria and Aspergillus were the most frequently isolated species. Regarding the outcome, 36 patients (20.8%) were lost from follow-up. Among patients with known outcome, 94/137 patients (68.6%) are living, while 43/137 patients (31.4%) died. Conclusion: AR-CGD is predominant in Egypt; CGD must always be ruled out in any patient presenting with typical or atypical mycobacterial or BCG-disease. [ABSTRACT FROM AUTHOR]

How do objects narrate the past, the everyday, and interrogate im/possible futures? How do they undo our 'ideas of home'? What affects do they gather and what subjectivities and different forms of intimacy do they call into conversation? This compendium article brings a visual artist together with nine early career academics researching and archiving fragments from homes in Egypt, Sudan, and Palestine (and their global connections). In doing so the piece offers different practices of narrating and visualising stories of and from home. The article moves from bridges and infrastructure to food and clothes and walls. Through attending to these fragments, the authors invoke questions about the ways in which objects archive colonialism, resistance, revolts, neoliberalism, consumerism, dispersion, migration, and exile. At the core of the article is the visual artist Azza Ezzat's creative interpretation of these nine stories, with a visual rendition that asks how fragments of home become interwoven aesthetically. Ezzat is an Egyptian visual artist whose practice relies on unpacking urban elements and recreating an alternative geography of urban space. [ABSTRACT FROM AUTHOR]

Background: In this study, the effect of heavy metals accumulation influence was evaluated on adult crayfish Procambarus clarkii (Decapoda, Astacidea) collected from three different Governmental locations (Kafr El-Shaikh, El-Menofya, and El-Gharbiya) of the Egyptian Delta. The activity of super oxidase dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) of gills, hepatopancreas, and muscle tissue were measured. SDS Polyacrylamide gel electrophoresis (SDS-PAGE) and West blotting technique were performed to detect MT Protein expression. Results: The results revealed that Kafr El-Shaikh reflected the highest Superoxide dismutase (SOD), Catalase, and Glutathione S-transferase (GST) activity levels (97.2 u/100 mg, 28.5 u/100 mg, and 8.3 nmol mg (-1) protein min (-1) respectively. Superior protein polymorphism % (30%) remarked collected Freshwater crayfish P. clarkii from Kafr El-Shaikh location. Varied protein polymorphism % was shown between collected crayfish from El-Menofya, and El-Gharbiya locations (5.5 and 6.2 respectively) Increasing Metallothioneins intensity (15.4%) for collected Freshwater crayfish Procambarus clarkii from Kafr El-Shaikh Location. Conclusion: Heavy metal stress influences antioxidant status and also induces increasing Metallothioneins intensity, especially samples that were collected from the Kafr El-Shaikh area.

Background: COVID-19 precipitated a plethora of mental health difficulties, particularly for those with pre-existing mental health concerns such as depression or addictive tendencies. For some, the distress that emanated from the experience of the pandemic prompted excessive engagement in the safety of online interactions on social media. The present study examined whether variation in individuals' sense of control explained the association between depression and addictive social media use. Method: A sample of 1322 participants from two Middle Eastern nations provided data collected during the peak of the pandemic from February to May 2021. A combination of convenience and snowball sampling were used to recruit and collect data from college-aged students enrolled at two universities in Egypt and the United Arab Emirates, respectively. This study adopted a cross-sectional design in which participants completed a self-administered survey that consisted of measures that assessed depressive affect, sense of control, and addictive social media use. Results: Depression was significantly and positively associated with addictive SMU. Sense of control was negatively related to both depression and SMU and significantly mediated the association between these two variables (β =.62, SE =.03, 95%CI.56,.68). Conclusion: This study identified a potential protective variable that could be targeted by psychological treatment to ameliorate the potential onset of addictive SMU in individuals with depressive symptoms under conditions of immense psychological distress such as a worldwide pandemic.

Background: Hepatitis C virus (HCV) is the primary contributor to chronic hepatic diseases. A rapid change in the situation took place with the advent of oral direct-acting antivirals (DAAs). However, a comprehensive review of the adverse event (AE) profile of the DAAs is lacking. This cross-sectional study aimed to analyze the reported Adverse Drug Reactions (ADRs) with DAA treatment using data from VigiBase, the WHO Individual Case Safety Report (ICSR) database. Methods: All ICSRs reported to VigiBase with sofosbuvir (SOF), daclatasvir (DCV), sofosbuvir /ledipasvir (SOF/LDV) and ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) in Egypt were extracted. Descriptive analysis was performed to summarize patients' and reactions' characteristics. Information components (ICs) and proportional reporting ratios (PRRs) for all reported ADRs were calculated to identify signals of disproportionate reporting. Logistic regression analysis was performed to identify the DAAs association with serious events of concern while adjusting for age, gender, pre-existing cirrhosis, and ribavirin use. Results: Out of 2925 reports, 1131 (38.6%) were serious. The most commonly reported reactions; anaemia (21.3%), HCV relapse (14.5%) and headache (14%). For the disproportionality signals; HCV relapse was reported with SOF/DCV (IC 3.65, 95% CrI 3.47–3.79) and SOF/RBV (IC 3.69, 95% CrI 3.37–3.92), while anaemia (IC 2.85, 95% CrI 2.26–3.27) and renal impairment (IC 2.12, 95% CrI 0.7–3.03) were reported with OBV/PTV/r. Conclusion: The highest severity index and seriousness were reported with SOF/RBV regimen. A significant association was found for OBV/PTV/r with renal impairment and anaemia although being the superior regimen in terms of efficacy. The study findings call for further population-based studies for clinical validation. [ABSTRACT FROM AUTHOR]

Decent Life is a presidential initiative that was launched in Egypt in the year 2019. The initiative targets complex problems facing underprivileged villages in Egypt. This paper uses a systems thinking approach to gain a holistic view of the initiative dimensions and address the interlinkages between these dimensions from the perspective of the Sustainable Development Goals (SDGs). The paper used a causal loop diagram (CLD) as a visualization of the systems thinking approach to analyze the interactions and interlinkage between all the components of the system. The Decent Life Initiative works on improving economic, social, and environmental infrastructures, which are related to SDGs. To achieve the initiative's goals effectively, this paper suggests working under the umbrella of three important factors: Raising awareness, adopting technology, and putting in place supportive policies and legislations. Finally, the paper suggests using system dynamics as a quantitative method, which uses stock-flow diagrams, to measure the impacts of the initiative on the achievement of the SDGs in Egypt.

Objectives: This study aimed to evaluate health related quality of life (HRQOL) in Egyptian children with systemic lupus erythematosus (SLE) using 3 different tools. Methods: In this questionnaire-based study, 100 children with SLE were included. HRQOL was assessed using the Pediatric Quality of Life Inventory Generic Core Scales (PedsQL™ 4.0 GCS), PedsQL™ 3.0 Rheumatology Module (PedsQL3-RM) and the Simple Measure of the Impact of Lupus Erythematosus in Youngsters (SMILEY). SLE disease activity index (SLEDAI) was used to evaluate activity and SLE International Collaborating Clinics/ American College of Rheumatology Damage Index (SDI) was used to evaluate chronic damage. Results: All mean scores of PedsQLTM4.0 GCS domains in SLE patients were lower than published normative data and previously published results of Egyptian healthy controls (p < 0.001). All mean scores of PedsQL-3RM domains were significantly lower than published normative data except for the treatment and pain and hurt domains (p = 0.1, 0.2 respectively). SMILEY scores were low and the lowest domain scores was "Burden of SLE". Longer duration of illness, higher cumulative steroid doses, higher SLEDAI and SDI scores and presence of obesity were associated with lower scores for all 3 tools (p < 0.001). Conclusion for Practice: The Arabic copies of PedsQL™ 4.0 GCS, PedsQL3-RM and SMILEY are easily used for Arabic speaking subjects and easily interpreted by physician and can be implemented for frequent monitoring of SLE HRQOL. Controlling the disease activity and using lowest doses of steroids and other immunosuppressive drugs are the corner stone strategies for improving HRQOL in SLE children. Significance: This is the first study to evaluate HRQOL scores in Egyptian children with SLE which were found to be lower than published data with long disease duration, high cumulative disease activity, use of steroids and presence of obesity are the main influential factors related to low QoL scores. Generic and disease specific questionnaires are easily used for Arabic speaking subjects and easily interpreted by physician and can be implemented for frequent monitoring of SLE HRQOL. Controlling the disease activity and using lowest doses of steroids and other immunosuppressive drugs are the corner stone strategies for improving HRQOL in SLE children. [ABSTRACT FROM AUTHOR]

Background: Because of COVID-19 pandemic, families across the world are experiencing new stressors that threaten their health, and economic well-being. Such a stress may jeopardize parents-children relationship. We aim to investigate the magnitude of child physical maltreatment (CPM) by parents in Egypt during the COVID-19 pandemic, to relate it to parents' stress, and to identify other potential risk factors. Methods: This cross-sectional study assessed parent-reported CPM and their personal experience of stress, depression, and anxiety among a sample of Egyptian parents using an electronic survey. It included sociodemographic data, Depression, Anxiety and Stress Scale (DASS-21), and the Child physical maltreatment scale (CPMS). We also briefly assessed COVID-19 -related data. Results: Out of 404 respondents, (62.9%) and (32.9%) reported performing minor and severe CPM toward their children during the past 3 months, respectively. The age of youngest child, and anxiety score were significantly correlated with both minor and severe forms of CPM. While number of children, and online education system ratings were only significantly correlated with severe CPM. Parental definition of CPM was significantly correlated to minor CPM, but not to severe CPM. Conclusions: CPM by parents is not uncommon in Egypt, especially during the COVID-19 pandemic. These findings highlight the importance of regular support and intervention that help parents learn parenting skills and the use of non-violent child disciplining methods. [ABSTRACT FROM AUTHOR]

The Paris Agreement targets to halt the progression of climate change necessitate global cooperation and renewable energy uptake in developed and developing countries at similar rates. This study explores the energy transition pathway options for Egypt across the power, heat, transport, and desalination sectors as a representative case study for other emerging sunbelt economies. The LUT Energy System Transition Model has been used to investigate the feasibility of six scenarios, including four variations of best policy, delayed policy, and current policy scenarios. The least-cost solution, achieving 100% renewable energy and zero CO 2 emissions by 2050, is dominated by solar photovoltaics at 90% of the total primary energy demand. Key transition enablers are the excellent and low-cost solar resources, energy storage, and Power-to-X technologies allowing high electrification and full sector coupling. The results reveal that the current and delayed policy scenarios are the most expensive pathways, highlighting the value of leapfrogging into a fully renewable system. Such a transition would require policy reforms that balance investment risks in emerging economies and enable its financial mobilisation. The structural results of this study provide a reliable guide for energy transition planning in Egypt as well as other emerging sunbelt economies. [ABSTRACT FROM AUTHOR]

Background: Many coronavirus disease 2019 (COVID-19) vaccines were approved worldwide. Their safety was the primary concern. In Egypt, Oxford-AstraZeneca (AZ) vaccine was the first approved vaccine initially for healthcare workers (HCWs). Objective: We aim to determine adverse events and hematological abnormalities following the COVID-19 AZ vaccine and estimate the infection rate of the candidates by COVID-19 between the first and second doses of vaccination. Methods: Within 8-10 days of receiving their initial dose of the AZ vaccine, 909 HCWs were assessed for adverse events as part of a prospective longitudinal study. Complete blood counts (CBCs) were evaluated before and one month after vaccination. Results: 37.2% of the candidates experienced side effects following vaccination. Pain at the injection site was the most common (25.4%) and more frequent in participants between 20 and 40 years (27.9%). The mean total leukocyte count (TLC), absolute leukocyte count (ALC), absolute neutrophil count (ANC), and absolute monocyte count (AMC) increased one month following vaccination (P < 0. 001). Sixty-six vaccinated HCWs were infected with COVID-19 between the two vaccine doses. 82% were infected after 14 days of the first dose, while 18% were infected before 14 days (P < 0.0001). Conclusions: Most of the vaccinated personnel did not experience any side effects after the first dose of the vaccine. Furthermore, the most common complaints were pain at the injection site, fatigue, fever, headache, arthralgia, myalgia, and chills. Infected people with COVID-19 after the first dose had significantly more severe disease if they were infected before 14 days than those who got infected later on. [ABSTRACT FROM AUTHOR]

Vibrio alginolyticus, Vibrio chlorea, and Enterococcus cloacae were the main bacterial pathogens investigated during recurrent episodes of mortalities among farmed flathead grey mullet (Mugil cephalus) in the Bahar El-Baqar area, Sharqia governorate, Egypt, during the summer season in 2021. Nevertheless, the contamination of water with heavy metals was evaluated. In this study, a total number of sixty moribund and freshly dead Mugil cephalus were examined clinically and upon post-mortem. Then, the bacterial isolates were subjected to bacteriological phenotypic examination, 16S rRNA gene sequencing, and antibiotic sensitivity testing. Histopathological screening and the immunity response of naturally infected M. cephalus were also implemented. In areas where bacterial strains were recovered in a high percentage, water contamination with Cu, Fe, and Ni was higher than the permissible limit. The results showed a high similarity (99–100%) to Vibrio and E. cloacae strains using phylogenetic analysis of 16S rRNA. Most isolates exhibited sensitivity to florfenicol, ciprofloxacin, and norfloxacin, while they were resistant to erythromycin and amoxicillin. Hemorrhage, oedema, hemosiderosis, and melanomacrophage activation in most affected tissues of infected M. cephalus were detected by light microscopy. Nevertheless, higher levels of AST and ALT, as well as serum inflammatory markers, CRP, and lysozyme activity, were shown in infected fish. There were higher MDA levels, along with a reduction of GSH, SOD, and catalase, in the gills and brain of infected M. cephalus, compared to the control fish. Our obtained data confirmed the high prevalence of Vibrio serovars and E. cloacae in infected grey mullets, describing their histopathological alterations, higher inflammatory response, and oxidative stress impact. These results could be useful indicators for understanding the pathogenesis of these pathogens in correlation with water parameter deterioration. Thus, the emergence of Vibrio and E. cloacae species in this study threatens the brackish water aquaculture industry in Egypt and poses a public health concern. [ABSTRACT FROM AUTHOR]

Theileriosis is a tick‐borne protozoal disease caused by a piroplasm of the genus Theileria. Hard ticks are obligate hematophagous ectoparasites that serve as vectors of Theileria spp. Studies of the presence of theileriosis in Egyptian dogs and associated ticks are scarce. This study was conducted to detect and identify Theileria spp. in dogs and Rhipicephalus sanguineus ticks and to monitor the epidemiological data of this disease. The prevalence rates of Theileria equi infection were 12.02%, 0.73%, 2.93%, and 1.83% by microscopic examination of dog blood, tick hemolymph, tick midgut, and tick salivary smears, respectively. Conversely, the T. equi prevalence in dog blood and associated ticks assessed by PCR was 25.81% and 10.42%, respectively. Epidemiological data about Theileria infection revealed a significant difference in the infection between different seasons and different dog breeds (p value <0.05), whereas host, sex, and age of dogs had no significant effect on the infection. Sequencing of PCR products showed that all PCR positive samples were infected with T. equi. Transmission electron microscopy (TEM) described the different stages of Theileria in the midgut and salivary gland of infected ticks. The current study confirmed that T. equi is not specific to equine hosts, and confirmed that dogs are a susceptible host to T. equi. [ABSTRACT FROM AUTHOR]
