A controlled study of virtual reality in first-year magnetostatics

Background: Bisphosphonates have previously been shown to increase the density of impacted graft bone. In the present study we hypothesise that bisphosphonates also reduce early stem subsidence. We examined the effect of locally applied bisphosphonate to allografts on prosthetic micromotion and bone density in femoral stem revision with impaction grafting. Methods: 37 patients were randomised to either clodronate or saline as local adjunct to the morsellised allograft bone. 24 patients were finally analysed per protocol and evaluated by dual-energy x-ray absorptiometry (DXA) during the first year and with radiostereometric analysis (RSA) for 5 years. Results: There were no significant differences neither in bone density, nor in migratory behaviour between the groups. The femoral stems had subsided 3.6 mm in both groups (p = 0.99) at 5 years and there was no difference as measured over time with mixed models analysis. The clinical outcome was good in both groups. Conclusion: Clodronate as a local addendum to allograft bone in hip revision did not increase bone density or reduce micromotion of the implant.

First Year Of Life

A double-blind controlled study to determine the effect on infections of repeated administration of large doses of gamma-globulin to premature infants revealed that significantly more of these infants had no infections and fewer had mild infections during the first year of life. The data also suggests that gamma-globulin afforded some amelioration of serious but nonfatal infections. Deaths from infection showed a similar trend in favor of the gamma-globulin group, but this difference on its own was not significant.

Background: Hospitalized patients with advanced heart failure often experience acute and/or chronic pain. While virtual reality has been extensively studied across a wide range of clinical settings, no studies have yet evaluated potential impact on pain management on this patient population. Aim: To investigate the impact of a virtual reality experience on self-reported pain, quality-of-life, general distress, and satisfaction compared to a two-dimensional guided imagery active control. Design: Single-center prospective randomized controlled study. The primary outcome was the difference in pre- versus post-intervention self-reported pain scores on a numerical rating scale from 0 to 10. Secondary outcomes included changes in quality-of-life scores, general distress, and satisfaction with the intervention. Setting/participants: Between October 2018 and March 2020, 88 participants hospitalized with advanced heart failure were recruited from an urban tertiary academic medical center. Results: Participants experienced significant improvement in pain score after either 10 minutes of virtual reality (change from pre- to post −2.9 ± 2.6, p < 0.0001) or 10 minutes of guided imagery (change from pre- to post −1.3 ± 1.8, p = 0.0001); the virtual reality arm experienced a 1.5 unit comparatively greater reduction in pain score compared to guided imagery ( p = 0.0011). Total quality-of-life and general distress scores did not significantly change for either arm. Seventy-eight participants (89%) responded that they would be willing to use the assigned intervention again. Conclusion: Virtual reality may be an effective nonpharmacologic adjuvant pain management intervention in hospitalized patients with heart failure.

Abstract Background Postural balance is an important rehabilitation outcome, and screening stroke patients for confidence in postural balance during rehabilitation and before hospital discharge is recommended. Early supported discharge could improve postural balance self-confidence. This study aimed to investigate associations between patient self-confidence in postural balance and observer-assessed postural balance and anxiety during the first year after stroke. Whether very early supported discharge (VESD) affects self-confidence in postural balance compared with standard discharge was also evaluated. Methods A longitudinal trial for with data extracted from a randomized controlled study of 140 adults with confirmed stroke was conducted. The experimental group received VESD. The control group was discharged according to the standard routine. Postural balance was assessed with Berg Balance Scale (BBS), Timed Up and Go (TUG) test, and Falls Efficacy Scale. Anxiety was assessed with the Hospital Anxiety and Depression Scale. Spearman’s rank correlation coefficient (rho) was used to test associations between independent variables. The Wilcoxon signed-rank test was used to examine differences over time. A single test, according to Eid, Gollwitzer, and Schmidt, was used to test temporal differences in correlation. Results The correlation between self-confidence in postural balance and observer-assessed postural balance was 0.62–0.78 in the first year after stroke. The correlation between self-confidence and anxiety was 0.22–0.41 in the first year after stroke. Correlations did not differ by group affiliation at any time point when the postural balance was assessed with BBS. The intervention group had a significantly higher correlation (r = − 0.709) than the control group (r = − 0.416) when postural balance was assessed with the TUG test 1 month after discharge. There were no significant differences in correlations between confidence in postural balance and anxiety between the two groups at any time point. Conclusions Patients with mild stroke can accurately assess their confidence in performing daily activities without falling. VESD does not substantially affect the correlation between self-confidence in postural balance and observer assessed postural balance and is safe to use as an alternative to standard discharge. Assessment of self-confidence can provide important information for rehabilitation planning and supporting the physical activity of patients after discharge.

Mixed Methods Approach

This study investigates English language learner (ELL) perceptions of using a prototype virtual reality learning environment (VRLE) designed for teaching and learning writing structure. A mixed-methods approach was used, incorporating pre- and post-participation questionnaires, as well as semi-structured interviews. Participants consisted of 10 ELLs enrolled in first year English for Academic Purposes (EAP) courses at a university in Mainland, China. Results indicate that while the majority of students enjoyed using the VRLE, they maintained varying attitudes regarding the usefulness of the VRLE. Additionally, results from a correlation analysis suggest that learners' attitudes towards the material or content being learned (EAP writing) significantly correlates with learners' attitudes towards using the VRLE for learning writing structure.
