Objective The purpose of the current study was to determine the dynamic knee valgus angulation (DKVA) among sedentary young adults and the relationship of DKVA with triple hop distance and athletic single leg stability. Methods A cross sectional study was conducted on a sample of 72 healthy sedentary young adults aged 18-26 years out of which 29 (38.33%) were males and 43 (61.76%) were females. DKVA, single leg triple hop distance and athletic single leg stability were the outcome measurements for the study. Shapiro-Wilk and Kolmogorov Smirnov tests were used to determine normality of data. Independent t-test and Mann Whitney-U test were used for gender based comparison, paired t-test and Wilcoxon signed-rank test for comparing values of right and left leg, Freidman test for comparing the values of DKVA in different tasks and Pearson and Spearman correlation was used to determine relationship between two variables. Confidence interval was kept at 95% and p<0.05 was considered significant. Results DKVA was found to be lower for dominant leg in all tasks, and higher for single leg tasks as compared to drop jump screening test for both legs. Greater values of DKVA were observed in females in all tasks. Single leg triple hop distance and athletic single leg stability scores were higher in males as compared to females. No significant correlation of DKVA was observed with single leg triple hop distance and athletic single leg stability. Continuous...

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.

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.

This quasi-experimental research examined the effects of the process/genre approach (PGA) with the integration of blogs in EFL university-level students’ writing classrooms. This was a mixed-method study in which the participants’ essays and adopted questionnaires contributed to accumulating quantitative data while the interviews and observations provided qualitative data. The study took place over ten weeks at a university in central Taiwan in which paper-pencil instruction was applied in the control group, while blog instruction was employed for the experimental group. The students’ essays were computed by applying a paired-sample t-test, and the questionnaires were analysed by applying a Wilcoxon signed-rank test to determine whether there were any statistically significant differences in terms of the students’ writing performance and perceptions toward the PGA and blog writing after comparing the results of the pre-test and the post-test. The qualitative data was analysed to provide in-depth evidence to support the quantitative results. After the data analysis was completed, the paired-sample t-test demonstrated that there were significant differences in terms of the students’ writing performance in both groups, which demonstrates how the PGA developed the EFL university students’ writing performance. Because the students had more interactive opportunities to be exposed to the language inputs, this approach facilitated their English writing performance. The Wilcoxon signed-rank test presented that the students revealed positive attitudes toward writing blogs and also positive affections toward blog writing because they had higher levels of satisfaction and lower levels of apprehension when blogging. Moreover, there was a significant difference in terms of the factor of “learning with peers” in the control group since the PGA provided more interactive and communicative opportunities. The students also indicated greater understanding about their writing samples in the experimental group, since they were allowed to refer to the instructional contents on the blogs anytime and anywhere.
