Virtual Reality Simulation in Nursing and Midwifery Education: A Usability Study.

Virtual reality simulation offers students the opportunity to acquire clinical and psychomotor skills in a safe and interactive environment. This study describes the usability of virtual reality simulation among undergraduate nursing and midwifery students. Participants were recruited using convenience and snowball sampling and engaged in a 20-minute virtual reality simulation scenario of their choice. They then completed a 21-item survey comprising a sociodemographic questionnaire, the System Usability Scale, a satisfaction questionnaire, and open-ended questions. Quantitative data were analyzed using descriptive statistics, and qualitative data were analyzed using deductive content analysis. Forty-three students participated in this study. The mean (SD) System Usability Scale score was 75.87 (13.7), indicating that virtual reality simulation was acceptable. Almost all participants were either "extremely satisfied" or "somewhat satisfied" with virtual reality simulation, which was perceived as informative and enjoyable, fostering safe and self-directed learning without causing patient harm. Participants recommended using virtual reality simulation to practice clinical skills, prepare for clinical placements, and learn about rare clinical situations. Virtual reality simulation needs to be underpinned by a strong pedagogy and aligned with learning outcomes. Educators and students should be trained in virtual reality simulation prior to its integration into the curriculum.

Nurses and midwives' experiences with peer-group clinical supervision intervention: A pilot study.

AIM: This study aimed to evaluate differences in supervisees' understanding of clinical supervision and their perceptions of organisational functioning before and after engaging in peer-group clinical supervision. BACKGROUND: Protected reflective time allows discussion of complex issues affecting health care. Peer-group clinical supervision is one model of clinical supervision that could facilitate this, but it is poorly understood. METHODS: A pre-post intervention pilot study was performed. The intervention was delivered over a 12-month period. Data were collected using surveys on demographic and work-related factors and experience of clinical supervision pre- and post intervention. RESULTS: Adaptability increased significantly between the pre- and post surveys. The post survey data showed finding time for clinical supervision scoring lowest with open-ended comments reinforcing this. The supervisees found the sessions to offer a safe place despite initial concerns. CONCLUSION: The peer-group model of clinical supervision allowed supervisees to build a rapport and trust with their colleagues and share experiences. IMPLICATIONS FOR NURSING MANAGEMENT: The benefits to participating in peer-group clinical supervision traversed the individual and organisation. These data support the implementation of such sessions while addressing workload and time pressures to aid participation.

Is high prevalence of Vitamin D deficiency evidence for autism disorder?: In a highly endogamous population.

AIM: To determine the association between Vitamin D and autism, and the difference in level of Vitamin D in autism children and control. DESIGN: Case-control study conducted between June 2011 and May 2013, among autism at the Hamad Medical Corporation and controls at the School Health Clinics and Primary Health Care Clinics. SUBJECTS AND METHODS: A total of 254 cases and 254 controls. The Autism Diagnostic Observation Schedule-Generic is a semi-structured, standardized assessment of social interaction, communication, play and imaginative use of materials for individuals suspected of having autism spectrum disorders. Data on clinical manifestations and laboratory, family history, body mass index (BMI) and clinical biochemistry variables including serum 25-hydroxy Vitamin D, calcium, phosphorus and magnesium were obtained. Univariate and multivariate statistical analyzes were performed. RESULTS: Of the total number of 508 children surveyed, 254 of autism and 254 of healthy children were contacted. The mean age (± standard deviation, in years) for autism versus control children was 5.51 ± 1.58 versus 5.76 ± 1.56. There were statistically significant differences between autism and healthy children control subjects with respect to educational level of mother (P = 0.016); occupation of mother (P = 0.005); BMI (P < 0.001); consanguinity (P = 0.015); exposure to sun (P = 0.002) and walking time per day <60 min (P < 0.001). The mean value of Vitamin D in autism children was much lower than the normal value, and there was a significant difference found in the mean values of Vitamin D between autism (18.39 ± 8.2 with median 18) and versus control children (21.59 ± 8.4) (P < 0.0001) and with median 21 (P = 0.004). Besides mean values of calcium, phosphorous, magnesium, glucose, potassium and alkaline phosphate were statistically significant higher in control healthy children compared to autism children (P < 0.001). Multivariate logistic regression analysis revealed that the mean serum Vitamin D level, calcium, consanguinity, BMI, physical activity, child order, and ferritin, were considered as the main factors associated with autism. Of total 254 of autism children, 14.2% had severe Vitamin D deficiency (<10 ng/ml), 43.7% had moderate insufficient levels (between 10 and 20 ng/ml), 28.3% had mild insufficient levels (between 20 and 30 ng/ml), and only 13.8% of autism had sufficient levels (>30 ng/ml). Similarly, of the total 254 of healthy children 8.3% had severe Vitamin D deficiency (<10 ng/ml), 37% had moderate insufficient levels (between 10 and 20 ng/ml), 37.4% had mild insufficient levels (between 20 and 30 ng/ml), and only 17.3% had sufficient levels (>30 ng/ml). Furthermore, there was statistically significant differences between autism and control subjects with respect to the serum level of Vitamin D (P = 0.023). CONCLUSION: The present study revealed that Vitamin D deficiency was higher in autism children compared to healthy children and supplementing infants with Vitamin D might be a safe and more effective strategy for reducing the risk of autism.

Prevention of aflatoxin B1-initiated hepatotoxicity in rat by marine algae extracts.

Chemoprevention by extracts of Laurencia obtusa (E1) and Caulerpa prolifera (E2) collected from the Egyptian coast of the Red Sea against aflatoxin B(1) (AFB(1))-initiated hepatotoxicity in female Sprague-Dawley rats has been studied. Animals were fed aflatoxin-contaminated diet (3 mg kg(-1) diet) for 6 days then treated orally with pure aflatoxin B(1) (AFB(1)) (200 microg kg(-1) b.w.) for 4 days either in combination with or before E1 or E2 administration (50 mg kg(-1) b.w.). AFB(1) resulted in a signicant increase in serum alpha fetoprotein, carcinoembryonic antigen, tumor necrosis factor alpha, nitric oxide, interleukin-1alpha, procollagen III and lipid peroxidation level in the liver. It caused a signicant decrease in food intake, body weight, serum leptin, the activities of glutathione peroxidase, superoxide dismutase and DNA and RNA concentrations in the liver. Cotreatment with AFB(1) and E1 or E2 resulted in an obvious improvement in all tested parameters. Noteworthy, E2 was more effective than E1 in the protection against AFB(1)-induced hepatotoxicity.
