Feasibility and benefits of a videoconferencing-based home exercise programme for paediatric cancer survivors during the coronavirus disease 2019 pandemic.

OBJECTIVE: We aimed to determine the feasibility and benefits of a videoconferencing-based home exercise programme to improve health-related quality of life (HRQOL), posttraumatic growth and physical strength levels of paediatric cancer survivors during the coronavirus disease 2019 (COVID-19). METHODS: Eight paediatric cancer survivors participated in the intervention for 8 weeks. The programme comprised home exercise sessions administered using Zoom, a videoconferencing platform. The supervised exercise sessions were performed two times per week; the participants were taught to perform joint exercises at home for the remaining 5 days of the week. HRQOL, posttraumatic growth and physical strength levels were assessed at baseline and after the intervention. RESULTS: The rates of recruitment, retention and attendance were 52.9%, 88.9% and 98.4%, respectively. There were no cases of adverse events. The programme significantly improved flexibility (z = -2.21, p = 0.03), muscle strength (z = -2.67, p = 0.01) and power (z = -2.41, p = 0.02) among five domains of physical fitness measured using a physical activity promotion system and also improved total physical strength (z = -2.67, p = 0.01). Posttraumatic growth decreased slightly, whereas HRQOL improved slightly; however, the change was not statistically significant. CONCLUSION: The study findings present preliminary evidence of the feasibility and benefits of this videoconferencing-based home exercise programme among paediatric cancer survivors.

The Association Between Temperament and Characteristics, Smartphone App Use Patterns and Academic Performance of University Students.

BACKGROUND: Smartphone use patterns may predict daily life efficacy and performance improvements in sports. Additionally, personal characteristics may be associated with smartphone overuse. METHODS: We investigated the correlation between the temperament and character inventory (TCI) and academic performance using smartphone log data. We hypothesized that the elite and general groups, divided based on academic performance, differed according to the TCI and downloadable smartphone apps (applications). Additionally, we hypothesized a correlation between smartphone app usage patterns and TCI. A total of 151 students provided smartphone log data of the previous four weeks. They also completed the TCI and provided academic records of the previous year. RESULTS: The first and second most frequently used apps by both groups of students were social networking and entertainment, respectively. Elite students scored higher on novelty seeking, reward dependence, persistence, self-directedness, and self-transcendence than general students. In all participants, the usage time of serious apps was correlated with the scores for novelty seeking (r = 0.32, P < 0.007), reward dependence (r = 0.32, P < 0.007), and self-transcendence (r = 0.35, P < 0.006). In the elite group, the usage time of serious apps was correlated with the scores for novelty seeking (r = 0.45, P < 0.001), reward dependence (r = 0.39, P = 0.022), and self-transcendence (r = 0.35, P = 0.031). In the general group, the usage time of serious apps was correlated only with self-transcendence (r = 0.32, P < 0.007). CONCLUSION: High usage time of serious apps can help sports majors to excel academically. Particularly among sports majors, serious apps are related to activity, the desire for rewards and recognition, and the tendency to transcend themselves.

Effects of triamcinolone-impregnated nasal dressing on subjective and objective outcomes following endoscopic sinus surgery.

The aim of this study was to compare the effects of triamcinolone (TA)- and saline-soaked biodegradable nasal dressing on subjective symptoms, wound healing and improvement of olfactory dysfunction in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) after undergoing endoscopic sinus surgery (ESS). The study was a prospective, randomized, double-blinded, placebo-controlled study. A total of 80 patients undergoing bilateral ESS for CRSwNP were enrolled and randomly assigned to two groups. Nasal dressing was impregnated with normal saline in the control group, while patients received triamcinolone-impregnated dressing in the TA group. Sino-Nasal Outcome Test 20 (SNOT-20) and Korean Version of the Sniffin' Stick (KVSS) II test were used to assess the patients' condition preoperatively and at postoperative 1 and 3 months. Lund-Kennedy (L-K) and perioperative sinus endoscopy (POSE) scores were assessed on postoperative months 1, 2, and 3. There were significant differences between the control group and the TA group in terms of postoperative L-K scores and POSE scores at 1 and 2 months. The postoperative endoscopic scores were significantly decreased in the TA group compared to the control at 1 month. Olfactory functions were significantly improved at postoperative 3 months (p = 0.0099) compared to the preoperative score in the TA group. Significant improvement in the olfactory functions among anosmic and hyposmic patients at postoperative 1 month (p = 0.0475) and 3 months (p = 0.0019) compared to their preoperative olfactory function score was observed only in the TA group. TA-impregnated dressing had a significant advantage over saline-soaked dressing with regard to postoperative wound healing and improvement of olfactory function.

Effects of Virtual Reality Pilates Training on Duration of Posture Maintenance and Flow in Young, Healthy Individuals: Randomized Crossover Trial.

BACKGROUND: This study explored the use of virtual reality (VR) technology to enhance the effectiveness and duration of low-intensity movements and postures in Pilates-derived exercises. We postulate that by leveraging the flow state in VR, individuals can engage in these exercises for longer periods while maintaining a high level of flow. OBJECTIVE: The purpose of this study was to compare differences in posture maintenance and flow between VR Pilates training and conventional Pilates training, and the correlation between the 2 factors. METHODS: The 18 participants in each group received either VR training or conventional training and were switched to the other training type after a 2-day wash-out period. Each group performed Pilates movements in a VR environment and a conventional environment, divided into 4 types. After training sessions, participants were evaluated for flow using a self-report questionnaire. In addition, a sports video analysis program was used to measure the duration of posture maintenance in 2 video-recorded sessions. Repeated-measures ANOVA and correlation analysis were performed on the measured duration of posture maintenance and flow scores. In all cases, the statistical significance level was set at P<.05. RESULTS: Results for the duration of posture maintenance verification by type showed that simple behavior (F1,16=17.631; P<.001), upper body-arm coordination behavior (F1,16=6.083; P=.04), upper body-leg coordination behavior (F1,16=8.359; P<.001), and whole-body coordination behavior (F1,16=8.426; P<.001) all showed an interaction effect at P<.05. Flow (F1,16=15.250; P<.001) also showed an interaction effect. In addition, significant correlations were determined between duration of all types of posture maintenance and flow in the VR training group at P<.05. CONCLUSIONS: Our results indicate that VR Pilates training may be more useful than conventional Pilates training in improving the duration of posture maintenance and that it promotes a significantly higher degree of flow when compared with conventional Pilates training.
