Outcome of Undergraduate Medical Education using Medical Simulation according to Students’ Feedback

Objectives: This study aimed to determine students’ overall satisfaction with clinical simulation sessions and compare the satisfaction levels of obstetrics/gynaecology (OBGYN) students (group one) and internal medicine students (group two). Methods: This study was conducted from January to June 2019 at the Arabian Gulf University, Manama, Bahrain. Students from year five were included and offered sessions that used simulations to support clinical skill development. Data were collected using a five-point Likert scale (i.e. strongly agree, agree, neutral, disagree, strongly disagree) via feedback forms. Results: A total of 150 students were included in this study (response rate: 99.07%). In groups of seven, the students attended five cycles of simulations with two sessions per cycle in each specialty over six months. The mean percentage of responses of “strongly agree” and “agree” was 97.8 ± 2.3% in group one and 95.7 ± 2.7% in group two. The satisfaction scores of group one were higher than those from group two for all statements. Significant differences were found between groups one and two in their responses to the statement of whether the simulation session was relevant to clinical practice (100% versus 92.9%; P <0.001) and whether the debriefing session was useful (98.1% versus 94.8%; P = 0.015). Conclusion: Students indicated high satisfaction after attending the simulation sessions; however, OBGYN students were more satisfied compared to those studying internal medicine.Keywords: Simulation Training; Patient Simulation; High Fidelity Simulation Training; Undergraduate Medical Education; Bahrain

Calculation and Tabulation of Efficiencies for Tungsten Foil Positron Moderators

Monte Carlo radiation transport simulations were used to calculate the positron stopping profiles in tungsten positron moderator foils. Stopping profiles were numerically integrated with efficiency kernels derived from Green\u27s function solutions of the 3D diffusion equation to determine the moderation efficiency in both the backscattering and transmission geometries. Stopping profiles and efficiencies were calculated for positron energies from 10 keV to 10 MeV and incident angles from 0° to 75°. The resulting efficiencies agreed with other calculated and measured values in the literature, especially when similar values of the positron diffusion length and surface emission branching ratio were used. Large discrepancies with some of the values reported in the literature are mainly attributed to differences in foil manufacture and surface condition - factors which are known to greatly influence the diffusion length - as well as work function and branching ratios. This work provides tabulated efficiencies for tungsten foil moderators that can be interpolated and integrated with a positron flux having arbitrary energy and angular distributions

International survey of Cronobacter sakazakii and other Cronobacter spp. in follow up formulas and infant food

A coordinated survey for Cronobacter and related organisms in powdered infant formula, follow up formula and infant foods was undertaken by 8 laboratories in 7 countries in recognition of and in response to the data needs identified in an FAO/WHO call for data in order to develop global risk management guidance for these products. The products (domestic and imported) were purchased from the local market and were categorised according to their principle ingredients. A total of 290 products were analysed using a standardised procedure of pre-enrichment in 225 ml Buffered Peptone Water (BPW), followed by enrichment in Enterobacteriaceae Enrichment (EE) broth, plating on the chromogenic Cronobacter Druggan–Forsythe–Iversen (DFI) agar and presumptive identification with ID 32 E. Presumptive Cronobacter isolates were identified using 16S rRNA gene sequence analysis. Aerobic plate counts (APC) of the products were also determined on nutrient agar. Fourteen samples had APC > 105 cfu/g, 3 of which contained probiotic cultures. C. sakazakii was isolated from 27 products; 3/91 (3%) follow up formulas (as defined by Codex Alimentarius Commission), and 24/199 (12%) infant foods and drinks. Hence C. sakazakii was less prevalent in follow up formula than other foods given to infants over the same age range. A range of other bacteria were also isolated from follow up formulas, including Acinetobacter baumannii, Enterobacter cloacae, Klebsiella pneumoniae, Citrobacter freundii, and Serratia ficaria. There was significant variation in the reconstitution instructions for follow up formulas. These included using water at temperatures which would enable bacterial growth. Additionally, the definition of follow up formula varied between countries

Shyness and its Relation with Self-esteem in Light of Some Variables

This study aimed at addressing shyness for learning disabilities students in the province of Irbid in the Hashemite Kingdom of Jordan. The descriptive-correlative approach was used. The sample consisted of (250) male and female learning disabilities students of grades two and four at public school in the province of Irbid. To achieve study objectives, shyness scale was developed, and the validity and reliability of its indicators we verified. Findings revealed that the level of shyness for learning disabilities students in the province of Irbid was moderate. They, also, revealed that the presence of statistical differences in the level of shyness for learning disabilities students attributable to the variable of gender. These differences came in favor of females. Furthermore, findings revealed the absence of statistical differences attributable to grade. In light of the findings, the researcher recommends raising the self-esteem level for students through co-operation between school administrations, teachers and guardians. It is also recommended that other researchers to conduct other developmental studies and compare the shyness levels for students in multiple age groups and environments

Musculoskeletal Disorders and Association with Social Media Use Among University Students at the Quarantine Time Of COVID-19 Outbreak

Introduction: COVID-19 period was characterized by lockdown and quarantine, the aim of this cross-sectional analytical study is to investigate the effect of COVID-19 quarantine on social media use, and its association with musculoskeletal disorders (MSD) among university students. Methods: A cross sectional study was conducted among Al-Quds University students. 317 students (average age of 20.34 years) participated in this study. A self-designed questionnaire was used to collect data which was sent to students on social media using a simple random method in almost all academic year phases. Results: There was a statically significant increase in the following variables during quarantine compared to before (P0.05). There was no statistically significant difference in time spent on exercise before and during quarantine with average time before the quarantine of 0.80 hours to 0.7 hours during the quarantine (P>0.05). There was a statistically significant increase of severity of Musculoskeletal disorders (MSD) as measured by a scale of 0-10 during the quarantine (P<0.05) in terms of severity of headache (2 to 2, 78), neck pain (2.06 to 2.80), and back pain (2.17 to 3). This increase in the three dominant MSD was positively correlated with the hours of use of laptops, computers, and mobile phones, for communication and education (P<0.05). Statistically significant negative correlation was found in between night sleeping hours and severity of MSD reported by students (P<0.05). Age was correlated with less use of social media for leisure and with more exercise (P<0.05). StudentsConclusion: Quarantine increased the time of use of social media, and in turn increases the prevalence and severity of MSD among university

Structural, elastic, mechanical and thermodynamic properties of Terbium oxide: First-principles investigations

First-principles investigations of the Terbium oxide TbO are performed on structural, elastic, mechanical and thermodynamic properties. The investigations are accomplished by employing full potential augmented plane wave FP-LAPW method framed within density functional theory DFT as implemented in the WIEN2k package. The exchange-correlation energy functional, a part of the total energy functional, is treated through Perdew Burke Ernzerhof scheme of the Generalized Gradient Approximation PBEGGA. The calculations of the ground state structural parameters, like lattice constants a0, bulk moduli B and their pressure derivative B′ values, are done for the rock-salt RS, zinc-blende ZB, cesium chloride CsCl, wurtzite WZ and nickel arsenide NiAs polymorphs of the TbO compound. The elastic constants (C11, C12, C13, C33, and C44) and mechanical properties (Young's modulus Y, Shear modulus S, Poisson's ratio σ, Anisotropic ratio A and compressibility β), were also calculated to comprehend its potential for valuable applications. From our calculations, the RS phase of TbO compound was found strongest one mechanically amongst the studied cubic structures whereas from hexagonal phases, the NiAs type structure was found stronger than WZ phase of the TbO. To analyze the ductility of the different structures of the TbO, Pugh's rule (B/SH) and Cauchy pressure (C12–C44) approaches are used. It was found that ZB, CsCl and WZ type structures of the TbO were of ductile nature with the obvious dominance of the ionic bonding while RS and NiAs structures exhibited brittle nature with the covalent bonding dominance. Moreover, Debye temperature was calculated for both cubic and hexagonal structures of TbO in question by averaging the computed sound velocities
