    Introduction:: Pathology learning for medical undergraduate students is a challenging task. Kahoot! is a mobile game-based online digital formative assessment tool that can engage students in its learning. This study is the first to assess the effect of Kahoot! use on Pathology learning outside classroom using a comparative group with assessment done at the end of the course.Methods:: The study was carried out on the first-year Pathology students at Helwan University, Faculty of Medicine, after ending a basic Pathology course. The study is a retrospective quasiexperimental quantitative study. Academic performance of students in Pathology was compared between Kahoot! and non-Kahoot! users (55 students each). In addition, an online survey was introduced to the 55 Kahoot! user students to investigate their perceptions on it. Survey and test score data were analyzed by appropriate tests using IBM-SPSS (Statistical Package for Social Sciences). The level of significance was P < 0.05.Results:: Kahoot! enhanced Pathology understanding (83.6%), retaining knowledge (87.3%), made learning fun and motivating (89.1%). Other mentioned advantages of Kahoot! were practicing for exam (40%), simple and easy to use (36.4%), competitive (18.2%), self confidence booster (10.9%), forming a comprehensive image of the lecture (9%), quick (9%), and imagining skills booster (5.5%). Mentioned disadvantages included no explanation for the answers to questions (20%). A quarter of the students stated that the time limit for the questions was short (27.3%). Kahoot! use was significantly associated with better Pathology academic performance (P = 0.001), and it was not related to the general academic performance of the students (P = 0.06). Most users (85.4%) recommended its continuous future use.Conclusions:: The study offers an endorsement to the use of Kahoot! for gamifying formative assessment of Pathology and can provide a basis for the design of an online Kahoot! -based continuous formative assessment plans implemented outside-classroom in the Pathology curricula

    Background. Hepatitis C virus (HCV) is an underappreciated cause of pediatric liver disease, most frequently acquired by vertical transmission (VT). Current guidelines that include the option of screening infants for HCV RNA at 1–2 months are based on data prior to current real-time polymerase chain reaction (PCR)-based testing. Previous studies have demonstrated VT rates of 4%–15% and an association with high maternal viral load. We evaluated HCV RNA in infants with HCV VT and assessed maternal risk factors in a prospective cohort in Cairo, Egypt

    Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

    AbstractThe goal of this study was to determine the most reliable and efficient combination of design and construction methods required for vibro piles. For a wide range of static and dynamic formulas, the reliability-based resistance factors were calculated using EGYPT database, which houses load test results for 318 piles. The analysis was extended to introduce a construction control factor that determines the variation between the pile nominal capacities calculated using static versus dynamic formulae. From the major outcomes, the lowest coefficient of variation is associated with Davisson’s criterion, and the resistance factors calculated for the AASHTO method are relatively high compared with other methods. Additionally, the CPT-Nottingham and Schmertmann method provided the most economic design. Recommendations related to a pile construction control factor were also presented, and it was found that utilizing the factor can significantly reduce variations between calculated and actual capacities

    Background: planning a rehabilitation system is based on the actual information on the classification (types) of disability and existing rehabilitation facilities. Objective: The study aimed to point out the prevalence of different forms of disability in sample urban and rural areas in Qena, Upper Egypt. Method: The study was carried out through random distribution of 32294 questionnaires over randomly selected urban and rural areas in Qena. The questionnaire included 6 types of disabilities. The aim of the study and the components of the questionnaire were explained to each household. Participants were asked to check one or more types of disability they suffer if any.  Results: The information obtained showed a total of 1890 subjects suffering from movement disabilities, 3330 from vision disorders, 795 from hearing disorders, 1292 from learning disabilities, 135 from fits, 202 from strange behavior, and 184 from age-related disabilities. Furthermore, the number of disabled persons living in rural areas was bigger than those living in urban areas with hearing disabilities, learning disabilities, fits, and strange behavior. Meanwhile, the number of disabled persons living in urban areas was bigger than that who were living in rural areas with moving, seeing, and old age disabilities.&nbsp

    Objectives: To compare the changes of palatal volume and area in patients treated with tooth-tissue-borne palatal expanders (conventional Haas) and miniscrew-supported palatal expanders (modified Haas). Materials and methods: The sample included casts of 22 patients treated as part of a clinical study at the Department of Orthodontics, Al-Azhar University, to correct their crossbite malocclusion. Patients were divided equally into two groups upon arrival. The first group, with a mean age of 12 years and 6 months, received the miniscrew-supported palatal expander. The second group, with a mean age of 12 years and 2 months, received the Haas design-palatal expansion appliance. Pre- and post-expansion dental casts were cone beam computed tomography scanned and the slices were constructed into 3D volumes. Fully automated superimposition was done for pre- and post-expansion 3D models. Palatal volume and area were determined, and all measurements were carried out blindly. Paired t-test was used to assess the mean differences within each group and Welch's t-test was applied to assess the mean changes between the two groups. Shapiro-Wilk test was used to test for the normality of the data. Results: There were no statistical differences in volume changes either within each group or between the groups. Although area changes were statistically significant within each group, the difference between the groups was not significant. Conclusions: Changes that result from the use of either method to expand the upper arch occur primarily in the shape of the palate, but not in its size

    Insights into the Electronic, Optical, and Anti-Corrosion Properties of Two-Dimensional ZnO: First-Principles Study

    The electronic, optical, and anticorrosion properties of planer ZnO crystal and quantum dots are explored using density functional theory calculations. The calculations for the finite ZnO quantum dots were performed in Gaussian 16 using the B3LYP/6-31g level of theory. The periodic calculations were carried out using VASP with the plane wave basis set and the PBE functional. The subsequent band structure calculations were performed using the hybrid B3LYP functional that shows accurate results and is also consistent with the finite calculations. The considered ZnO nanodots have planer hexagonal shapes with zigzag and armchair terminations. The binding energy calculations show that both structures are stable with negligible deformation at the edges. The ZnO nanodots are semiconductors with a moderate energy gap that decreases when increasing the size, making them potential materials for anticorrosion applications. The values of the electronic energy gaps of ZnO nanodots are confirmed by their UV-Vis spectra, with a wide optical energy gap for the small structures. Additionally, the calculated positive fraction of transferred electrons implies that electron transfer occurs from the inhibitor (ZnO) to the metal surface to passivate their vacant d-orbitals, and eventually prevent corrosion. The best anti-corrosion performance was observed in the periodic ZnO crystal with a suitable energy gap, electronegativity, and fraction of electron transfer. The effects of size and periodicity on the electronic and anticorrosion properties are also here investigated. The findings show that the anticorrosion properties were significantly enhanced by increasing the size of the quantum dot. Periodic ZnO crystals with an appropriate energy gap, electronegativity, and fraction of electron transfer exhibited the optimum anticorrosion performance. Thus, the preferable energy gap in addition to the most promising anticorrosion parameters imply that the monolayer ZnO is a potential candidate for coating and corrosion inhibitors

    The aim of this retrospective study was to assess, clinically and by MRI the short and long term effect of unilateral mandibular segmental repair by reconstruction plate on the ipsilateral and contralateral TMJ. 18 adult patients (12 male & 6 female) with history of mandibular reconstruction by titanium reconstruction bone plate were included. The age range was 32-66 years (mean 49years). The condyle in the reconstruction side was preserved. Based on the follow up period following the reconstruction, three groups were established. Magnetic resonance imaging was performed for all patients at the recommended follow up periods. Clinical examination also was done for all the patients in the same intervals. The result of this study demonstrated that there were no statistically significant differences noted between the three groups regarding the clinical data and also there were no significant differences between the MRI findings in all groups
