Validation of a Novel Traditional Chinese Medicine Pulse Diagnostic Model Using an Artificial Neural Network

In view of lacking a quantifiable traditional Chinese medicine (TCM) pulse diagnostic model, a novel TCM pulse diagnostic model was introduced to quantify the pulse diagnosis. Content validation was performed with a panel of TCM doctors. Criterion validation was tested with essential hypertension. The gold standard was brachial blood pressure measured by a sphygmomanometer. Two hundred and sixty subjects were recruited (139 in the normotensive group and 121 in the hypertensive group). A TCM doctor palpated pulses at left and right cun, guan, and chi points, and quantified pulse qualities according to eight elements (depth, rate, regularity, width, length, smoothness, stiffness, and strength) on a visual analog scale. An artificial neural network was used to develop a pulse diagnostic model differentiating essential hypertension from normotension. Accuracy, specificity, and sensitivity were compared among various diagnostic models. About 80% accuracy was attained among all models. Their specificity and sensitivity varied, ranging from 70% to nearly 90%. It suggested that the novel TCM pulse diagnostic model was valid in terms of its content and diagnostic ability

Learning Experience of Chinese Nursing Students during Clinical Practicum: A Descriptive Qualitative Study

The change in clinical environment can have a significant impact on nursing students’ clinical learning and as a consequence, to their competency. Students’ learning experiences could provide important insights for improving the existing approach towards clinical education. This descriptive qualitative study aimed to explore nursing students’ clinical learning experience. Focus group interviews were conducted with 20 final year nursing students studying a bachelor nursing programme at a self-financing tertiary institution in Hong Kong. Thematic analysis was conducted. 16 female and four male students were recruited. Six themes were identified: Anxiety towards clinical practicum, expectations of roles and responsibilities in practicum, ward environment, adequacy of support, learning attitude, and practicum arrangement. The findings suggest that nursing students are more discontented with their clinical training than before. Nursing faculty must look for possible ways to improve the clinical learning environment

Learning Experience of Baccalaureate Nursing Students with Challenge-Based Learning in Hong Kong: A Descriptive Qualitative Study

Nursing education has recently adopted challenge-based learning (CBL) to enhance nursing students’ competency in the 21st-century healthcare environment. Previous studies have not yet fully explored nursing students’ perceptions of CBL. This descriptive qualitative study aimed to investigate the learning experience of first-year baccalaureate nursing students engaging with CBL. Videotaped focus group interviews were conducted in a tertiary education institution in Hong Kong, China. The participants recruited for the study included ten Year 1 nursing students enrolled in a public health course delivered using CBL over the study period. The participants included four female and six male students. Five themes were identified: facilitation by teachers, familiarity with CBL, team communication, facilitating metacognitive development, and the application of theories into actual practices. The findings shed light on the potential application of CBL in nursing training as it can foster students’ metacognition, an important attribute for the modern-day workforce. Facilitating theoretical application into practice implies that CBL helps to fill the theory–practice gap that has long been a persistent issue in nursing training. Nonetheless, students encountered frustrating obstacles throughout the learning process, including ineffective group communication, unfamiliarity with the CBL process, and insufficient facilitation by teachers. Better preparation on the part of both teachers and students is critical to ensure that nursing students are gaining optimal benefits from the CBL process

Prediction of problem gambling by demographics, gaming behavior and psychological correlates among gacha gamers: A cross-sectional online survey in Chinese young adults

Objective: the objective of this study is to explore the association of problem gambling with demographics, psychological distress, and gaming behavior in young adult gacha gamers in Hong Kong. Materials and methods: cross-sectional data was collected in the first and fifth waves of COVID-19 pandemic in Hong Kong online. Participants who aged 18–25 years and had been playing gacha games over the past 12 months were recruited. Stepwise multiple regression was used to explore the association among risk of problem gambling, gaming behavior, participation in gaming activities and psychological distress. A two-sided p-value &lt;0.05 was considered as statistical significance. Results: three hundred and thirty-seven completed questionnaires were received with no missing data. 34.7% (n = 117) of the participants had non/low-risk of problem gambling. About 40% (n = 136) of them had moderate-risk and the remaining 25% (n = 84) were at high risk of problem gambling. A higher proportion of female participants (78.6%) were found in high-risk group as compared to 39.7% and 55.6% only in the non/low-risk and moderate-risk groups, respectively. The regression model (R 2 = 0.513, F = 71.895, p &lt; 0.001) showed that 51.3% of the variance of the total problem gambling score could be explained by stress, anxiety, monthly expenses on gacha purchases, number of motives for gacha purchase and number of gambling activities engaged. Conclusion: the present study provides empirical evidence to support the association between problem gambling and microtransaction especially for gacha which is the most popular type of video game microtransaction in Asia. The established regression model suggests that gacha gamers with higher risk of problem gambling tend to have greater stress, higher anxiety level, spend more on gacha purchase, have more motives for gacha purchases and engage in more gambling activities. In contrast to the extant literature, higher proportion of female participants in high-risk group indicates that female gacha gamers are also at very high risk of becoming problem gamblers. </p

The mediating effect of dispositional mindfulness on the association between UPPS-P impulsivity traits and gaming disorder among Asia-Pacific young adults

Background: little evidence is available to verify the mediating effect of dispositional mindfulness on the association between gaming disorder and various impulsivity traits. The present study aimed to investigate the mediating effect of dispositional mindfulness on the association between the five UPPS-P impulsivity traits and the risk of gaming disorder among young adults.Methods: it was an inter-regional cross-sectional study using online survey in Australia, Japan, The Philippines and China. Impulsivity measured by the UPPS-P Impulsive Behavior Scale-Short version; dispositional mindfulness measured by the Mindfulness Attention Awareness Scale; and the risk of gaming disorder measured by the Internet Gaming Disorder Scale were collected in the focal regions. Structural equation modeling was performed by SPSS AMOS version 26 to verify the study hypotheses. Bootstrapped 95% confidence interval was reported. Statistical significance was indicated by the p-value below 0.05.Results: among the 1,134 returned questionnaires, about 40% of them aged 18-20 years and 21-23 years, respectively. 53.8% were male. 40.7% had been playing digital and video games for over 10 years. The prevalence of gaming disorder was 4.32%. The model fitness indices reflected that the constructed model had an acceptable model fit (χ 2(118) = 558.994, p &lt; 0.001; χ 2/df = 4.737; CFI = 0.924; TLI = 0.890; GFI = 0.948; RMSEA = 0.058; SRMR = 0.0487). Dispositional mindfulness fully mediated the effect of positive urgency and negative urgency on the risk of gaming disorder. The effect of lack of premeditation on the risk of gaming disorder was partially mediated by dispositional mindfulness. However, dispositional mindfulness did not mediate the effect of sensation seeking on the risk of gaming disorder. Conclusions: the varied associations between dispositional mindfulness and the five impulsivity traits hints that improving some impulsive traits may increase dispositional mindfulness and so lower the risk of gaming disorder. Despite further studies are needed to verify the present findings, it sheds light on the need to apply interventions on gamers based on their impulsivity profile. Interventions targeting at emotion regulation and self-control such as mindfulness-based interventions seem to be effective to help gamers with dominant features of urgency and lack of premeditation only. Other interventions shall be considered for gamers with high sensation seeking tendency to enhance the effectiveness of gaming disorder prevention.</p
