Background: COVID-19 is a highly infectious, rapidly spreading disease without any proven vaccine or treatment. Poor knowledge, attitude and practices (KAP) toward COIVD-19 prevention measures among healthcare workers may lead to further transmission of the disease. Lack of attention towards non-frontline healthcare workers may put them at higher risk of infection from undetected cases. Here, we evaluate medical interns’ KAP toward COVID-19 prevention measures in the Kingdom of Saudi Arabia (KSA). Methods: We conducted a cross-sectional online survey. We distributed a structured questionnaire to the medical interns through different social media. Data was collected between April and May 2020. We estimated the prevalence of good KAP toward COVID-19 prevention measures. We did T-test or ANOVA to investigate the mean differences in KAP between socio-demographic groups. In addition, we did multivariable logistic regression analysis to investigate the socio-demographic determinants of good KAP.Results: Of the total 250 participants, 60% were males, 64% were aged between 20 and 25 years, and 90% was Saudi. 24% interns are relying on social media, newspaper, television or friends as primary source of COVID-19 information, while others are relying on formal sources like official websites of national and international bodies. Overall, the prevalence of good knowledge, attitude and practices are 38% (95% CI: 32.2-44.2), 55.2% (48.9-61.3) and 24% (19.1-29.7), respectively. Graduating from government universities are associated with higher odds of good knowledge (aOR: 3.87; 95% CI: 1.05-14.22) and positive attitude (aOR: 4.84; 95% CI: 1.28-18.23) than private or foreign universities. While, practicing in the west region-Mecca and Medina (aOR: 2.35; 95% CI: 1.05-5.23); and the North region-Hail, Jouf, Tabuk & Northern borders (aOR: 3.2; 95% CI: 1.32-7.75) are associated to higher odds of moderate/good practice compared to practicing in the central region- Riyadh and Qassim. Conclusions: Our findings reveal gaps in KAP among medical interns. Medical interns in Saudi Arabia are not deployed as front-line health worker to combat COVID-19. However, community transmission of COVID-19 make it critical to improve KAP of medical interns toward COVID-19 prevention measures. Repeated training to improve KAP and competency of the medical interns in this regard are warranted.

The results suggest that young adults with CMS are over-reliant on visual cues for postural stability, and that visual dependence is not influenced by gender.

Background: Motion sensitivity, or motion sickness, is common in modern vehicular and visually stimulating environments. Several studies have shown a relationship between motion sensitivity and decreased postural stability. We aimed to evaluate the effects of head motion (horizontal and vertical) on postural stability in healthy adults with and without chronic motion sensitivity (CMS). Methods: Sixty healthy adult men and women (age, 20-40 years) with CMS (CMS group, n = 30) and without CMS (non-CMS group, n = 30) participated in the study. Postural stability was assessed during three conditions (static, horizontal head motion, and vertical head motion) using computerized dynamic posturography. Group and condition-related differences in equilibrium scores were evaluated. Results: There was no significant group x condition interaction (F 2,114 = 0.9, partial ƞ 2 = 0.04, p = 0.35). However, significant condition-related differences in equilibrium scores were observed (F 2,114 = 26.4, partial ƞ 2 = 0.31, p < 0.001). Equilibrium scores were significantly worse in the horizontal and vertical head motion conditions compared to those in the static condition (p < 0.001), but were comparable in vertical and horizontal head motion conditions (p = 0.27). Conclusions: Postural stability was lower in the horizontal and vertical conditions compared to the static condition. However, horizontal and vertical head motions had comparable effects on postural stability in both CMS and non-CMS groups, contrary to our expectations.

BACKGROUND: Chronic motion sensitivity (CMS) is a combination of autonomic symptoms provoked by exposure to motion. The correlation between anxiety and CMS is not yet well understood. OBJECTIVES: 1) To compare median anxiety levels between young adults with and without CMS. 2) To examine the effect of anxiety on postural stability with immersion virtual reality. 3) To compare anxiety levels between sexes. METHODS: Participants included 60 adults (20–40 years), with and without CMS. After determining their current and general anxiety levels, postural stability was measured. RESULTS: There were significant differences in median (minimum, maximum) state- and trait-anxiety scores between participants with and without CMS, but no significant differences in median state- and trait-anxiety scores between males and females with CMS. There was a significant inverse relationship between state- and trait-anxiety scores and postural stability (ρ= –0.28, p = 0.03, and ρ= –0.32, p = 0.01, respectively). The stepwise regression analysis showed the Motion Sickness Susceptibility Questionnaire-Short Form score to be the only variable contributing significantly to postural stability (R2  = 26.2%; t = –4.5, p <  0.001). CONCLUSIONS: Young adults with CMS are more anxious, although anxiety does not contribute to postural stability in this group. Anxiety levels do not appear to differ between young adult males and females with CMS.
