Objective: To analyze the feasibility, safety, and acceptability of immersive virtual tasks. Methods: The authors recruited 11 young adults and 10 older adults. The participants performed three virtual reaching tasks while walking on a virtual path. The descriptive analysis and comparison between participants were performed using the Mann–Whitney U test and chi-square test for nonparametric and nominal variables, respectively. The authors also used analysis of variance for a between-groups comparison for normal variables. Results: Twenty percent of older adults and 81.8% of young adults completed all three tasks (chi-square test; p = .005). Both groups reported minor symptoms, with no significant differences. The older adults were more motivated to practice the tasks (Mann–Whitney U test; p = .015) and would be more likely to suggest them to others (chi-square test; p = .034). Conclusion: All three tasks were feasible for young adults. All participants, except for one, had cybersickness. The symptoms were mostly mild and subsided once the interaction was complete.

Background: Osteopenia or low bone density, generally considered the disease of the old, is now sneaking around the younger generation. The increase in frequency of low trauma fractures is raising an alarm. This study was aimed to explore the frequency of osteopenia amongst young adults in Karachi, Pakistan. Methods: Non-probability consecutive sampling was used to choose 116 subjects at Ziauddin University, Karachi, in January 2018. After informed consent participants underwent bone scans for measurement of bone mineral density on their calcaneus (bone in heel). Tocategorize osteopenia T-score between -1.0 and -2.5 was evaluated. All participants with T-score of -2.5 or below were identifiedas osteoporotic. The data were entered on IBM SPSS statistics version 20.0 and descriptive analysis was done. Results: Osteopenia was detected in 57 (49.1%) of the participants [42 (36.2%) male and 15 (12.9%) female] of which 38 (32.8%) belonged to aged 21 to 35 years. Osteoporosis was found in 20 (17.2%) of this group. In the older participants’ frequency of osteopenia and osteoporosis was 12.2% and 42.9% respectively. Chi square test indicated no significant association between age and bone scan results (p=0.432). Frequency of osteopenia was higher in males (56%) compared to females (36.6%) whereas, osteoporosis was higher in females (53.7%) than males (12%). Results showed statistically significant association (p>0.01) with gender and bone scan results. Conclusion: Almost half the young adults in our study classified for osteopenia. Lifestyle modification factors are hypothesized to play an important role towards this high frequency. Further studies should evaluate risk factors for osteopenia in younger population.

The aim of this retrospective study was to determine the prevalence of orthostatic hypotension (OH) among a convenience sample of older adults on two Acute Care of the Elderly (ACE) units of the ChristianaCare™ in Delaware. Another aim was to determine if subjects with documented OH experienced falls. Retrospective de-identified data was obtained from electronic medical records for the years 2015 to 2018. Among all patients who had valid first orthostatic vital sign (OVS) readings ( n = 7,745), 39.2% had orthostatic hypotension on the first reading. Among the patients, 42.8% were found to be hypotensive during OVS. Thirty-one (0.9%) of those with OH fell at some point during their stay. The odds ratio for falls in the presence of OH was 1.34 with a 95% confidence interval (0.82, 2.21), but a chi-square test failed to find significance ( p = .2494). The results could not determine if OVS should be mandatory in fall prevention protocols.

Background: Obstructive Sleep Apnea Syndrome (OSAS) is sleeping-disorder that’s characterized by recurrent episodes of upper airway obstruction during sleep. Fourteen percent of world populations suffer from OSAS. OSA patients are 7,5 to 20 times more likely to have difficulties with concentration, learning new tasks, and execution of monotonous tasks.Objective: The primary objective of this study was to investigate the relationship between Obstructive Sleep Apnea Syndrome (OSAS) and concentration level in young adults.Methods: This is an analytic observational study with cross-sectional design. Sampling was carried out with total sampling. Samples that qualified the inclusion and exclusion criteria were assessed by OSAS using the Epworth Sleepiness Scale (ESS)  questionnaire and Digit Symbol Substitution Test was used to assess the concentration level. The data were analyzed, using the chi-square test and the prevalence (PR) test.Results: The Chi-square test showed that there was a significant relationship between OSAS and concentration level (p=0.033). The Prevalence Ratio test found that OSAS decreased concentration level by 1,55 compared to not OSAS.Conclusion:  There was a significant relationship between OSAS and concentration level in young adults. OSAS patients are 1,55 more likely to have a decrease concentration level when compared with healthy individuals.

Introduction: Intra-oral and extra-oral tissues are at risk of damage during orthodontic treatment, most commonly oral ulcerations. Clinicians should assess and monitor every aspect of patient’s treatment procedure to achieve an uneventful and successful final result. Objective: To evaluate occurrence of oral ulcerations in patients undergoing orthodontic treatment. To evaluate the most common type of ulceration and to assess the management of such ulcerations by the orthodontists. Materials & Method: A questionnaire-based study was used among Nepalese and international orthodontists. Data were analyzed statistically using descriptive analysis and Chi-square test, p<0.05 was considered to be significant with a confidence interval of 95%. Result: Most common oral ulceration encountered during orthodontic treatment was traumatic ulceration which was managed by symptomatic measures. There was a statistically significant difference in the method of education to the patients among national and international orthodontists. Conclusion: Careful use of instruments, careful fitting and adjustment of the appliances should be done to avoid oral ulcerations during orthodontic treatment. Topical medicines can be used for management of such ulcers. Nepalese orthodontists should focus on using audio-visual aids for patient education as it has great promise in enhancing patient understanding and in prompting behavioral change.

ABSTRACT Background  In 2013, milestone ratings became a reporting requirement for emergency medicine (EM) residency programs. Programs rate each resident in the fall and spring on 23 milestone subcompetencies. Objective  This study examined the incidence of straight line scoring (SLS) for EM Milestone ratings, defined as a resident being assessed the same score across the milestone subcompetencies. Methods  This descriptive analysis measured the frequencies of SLS for all Accreditation Council for Graduate Medical Education (ACGME)–accredited EM programs during the 2015–2016 academic year. Outcomes were the frequency of SLS in the fall and spring milestone assessments, changes in the number of SLS reports, and reporting trends. Chi-square analysis compared nominal variables. Results  There were 6257 residents in the fall and 6588 in the spring. Milestone scores were reported for 6173 EM residents in the fall (99% of 6257) and spring (94% of 6588). In the fall, 93% (5753 residents) did not receive SLS ratings and 420 (7%) did, with no significant difference compared with the spring (5776 [94%] versus 397 [6%]). Subgroup analysis showed higher SLS results for residents' first ratings (183 of 2136 versus 237 of 4220, P &lt; .0001) and for their final ratings (200 of 2019 versus 197 of 4354, P &lt; .0001). Twenty percent of programs submitted 10% or more SLS ratings, and a small percentage submitted more than 50% of ratings as SLS. Conclusions  Most programs did not submit SLS ratings. Because of the statistical improbability of SLS, any SLS ratings reduce the validity assertions of the milestone assessments.
