Abstract Objective: Self-reported energy intake (EI) estimation may incur systematic errors that could be attenuated through biomarker calibration. We aimed to confirm whether calibrated EI was comparable to total energy expenditure (TEE) measured using the doubly labelled water (DLW) technique. Design: Cross-sectional study. Setting: General older population from the Kyoto–Kameoka Study, Japan. Participants: This study included sub- and main cohorts of 72 and 8,058 participants aged ≥65 years, respectively. EI was evaluated using a validated FFQ, and calibrated EI was obtained using a previously developed equation based on the DLW method. TEE was considered representative of true EI and also measured using the DLW method. We used a Wilcoxon signed-rank test and correlation analysis to compare the uncalibrated and calibrated EI with TEE. Results: In the sub-cohort, the median TEE, uncalibrated EI, and calibrated EI were 8,559 kJ, 7,088 kJ, and 9,269 kJ, respectively. The uncalibrated EI was significantly lower than the TEE (median difference = −1,847 kJ; interquartile range [IQR]: −2,785 to −1,096), although the calibrated EI was not (median difference = 463 kJ; IQR: −330 to 1,541). The uncalibrated (r = 0.275) and calibrated EI (r = 0.517) significantly correlated with TEE. The reproducibility was higher for calibrated EI (interclass correlation coefficient [ICC] = 0.982) than for uncalibrated EI (ICC = 0.637). Similar findings were observed when stratifying the sample by sex. For medians, uncalibrated EI was lower (˜17%) than calibrated EI in the main cohort. Conclusions: Biomarker calibration may improve the accuracy of self-reported dietary intake estimation.

Background: Dysmenorrhea or painful menstrual periods is one of the common health issues the female university students experience which intervenes with academic activities and quality of life. Objectives: We aimed to find the prevalence, intensity, extent of impairment in academic engagement, and efficacy of the management of dysmenorrhea among nursing students at Peradeniya University, Sri Lanka. Methodology: This cross sectional study comprised 86 female nursing students who represented all four academic years. A self-administered questionnaire was used. The intensity and level of dysmenorrhea were assessed. Association of the extent of working impairment with the level of pain determined by Pearson correlation. Duration of dysmenorrhea persisted before and after management was compared using paired sample t-test. The effectiveness of management was analyzed using Wilcoxon signed-rank test. Results: The prevalence of dysmenorrhea was 97.7%. The majority (54.7%) suffered moderate pain. Mean age of the participants was 24.02 (±1.503). During the period of dysmenorrhea, 32.6%, 33.7%, and 17.4% students experienced slight, moderate, and heavy impairment of overall academic engagement. A positive correlation was observed between level of pain and extent of academic impairment ( p < 0.05). The majority practiced pharmacological and non-pharmacological pain relieving methods together. Wilcoxon signed-rank test value revealed more negative ranks and statistically significant reduction in intensity in post-management period ( z = −7.793, p = 0). Post-management dysmenorrhea duration was significantly reduced than pre-management ( t76 = 8.984, p = 0). Conclusion: A substantial percent of undergraduates suffer from dysmenorrhea. It is associated impairment of overall academic engagement. The nursing students were able to manage dysmenorrhea successfully.

Visual acuity plays an important role in dentists’ vision in their daily clinical routine. This study aimed to determine dental students’ visual acuity without optical aids and when using magnification devices in simulated clinical conditions. The participants were forty-six students at the School of Dental Medicine with a visual acuity of 1.0 in decimal values or 100% in percentage. The central visual acuity was tested using a miniature Snellen eye chart placed in the molar cavity of a dental phantom, in simulated clinical conditions under five different settings (natural visual acuity, by applying head magnifying glasses x1,5 and binocular magnifying devices using Galileo’s x2,5/350 mm, Keplerx3,3/450 mm and Keplerx4,5/350 mm optical system). The Wilcoxon Signed Rank test shows that the distribution of measurements of the visual acuity undertaken by the application of magnifying devices (VNL, VGA2,5, VKP3,3, VKP4,5) contained higher values of visual acuity than those received by the use of natural vision (VSC) (p < 0.001 for the comparison to the VNL, VGA2,5, VKP3,3 and VKP4,5 groups). The highest and statistically most significant increase in visual acuity is achieved using the Keplerian telescope x4.5/350 mm. The application of magnifying devices provided dentistry professionals with better visual acuity, improving detail detection in an oral cavity during dental procedures by magnifying the oral structure. The use of magnification devices means much more precise work, decreases the operating time, improves posture and reduces muscle pain in the shoulder during dental treatment.

The Difference

In this chapter, the preferences of UNITEN students in using augmented reality technology user interface applications to solve selected engineering problems are compared. Cross sectional study design and Wilcoxon-Signed Rank Test approach were adopted to analyze the difference in the rankings of the engineering applications. Within a controlled environment, this research further applies “trials within the same session but with breaks between tasks,” an affirmed reliable method in measuring learnability that has been rarely explored by any related works locally. The results were captured through descriptive statistical analysis. The findings provided reliable evidences that multiple function user interface (MFIT) is more effective than the tangible user interface (TUI) for engineering students. Simultaneously, this research also presents evidences that MFIT is better than TUI in the engineering problem solving statistically.
