Symptom presentation and evolution in the first 48 hours after injury are associated with return to play after concussion in elite Rugby Union

Background:Return to play(RTP)in elite rugby is managed using a 6-stage graduated RTP protocol,which can result in clearance to play within 1 week of injury.We aimed to explore how symptom,cognitive,and balance presentation and evolution during concussion screens 2 h(head injury assessment(HIA2)and 48 h(HIA3)after injury were associated with time to RTP)to identify whether a more conservative graduated RTP may be appropriate.Methods:A retrospective cohort study was conducted in 380 concussed rugby players from elite men’s rugby over 3 consecutive seasons.Players were classified as shorter or longer returns,depending on whether RTP occurred within 7 days(allowing them to be considered to play the match 1 week after injury)or longer than 8 days,respectively.Symptom,cognitive,and balance performance during screens was assessed relative to baseline(normal or abnormal)and to the preceding screen(improving or worsening).Associations between sub-test abnormalities and RTP time were explored using odds ratios(OR,longer vs.shorter).Median day absence was compared between players with abnormal or worsening results and those whose results were normal or improving.Results:Abnormal symptom results during screens 2 h and 48 h after concussion were associated with longer return time(HIA2:OR=2.21,95%confidence interval(95%CI):1.39-3.50;HIA3:OR=3.30,95%CI:1.89-5.75).Worsening symptom number or severity from the time of injury to 2 h and 48 h post-injury was associated with longer return(HIA2:OR=2.49,95%CI:1.36-4.58;HIA3:OR=3.34,95%CI:1.10-10.15).Median days absence was greater in players with abnormal symptom results at both HIA2 and HIA3.Cognitive and balance performance were not associated with longer return and did not affect median days absence.Conclusion:Symptom presentation and evolution within 48 h of concussion were associated with longer RTP times.This may guide a more conservative approach to RTP,while still adhering to individualized concussion management principles.

Application of Role-Play in Oral English Teaching in Universities

Role-play is considered as a useful method to solve the problem of oral English teaching in universities. It's much more than a performance that learners can experience the real life in the classroom. Through its use in the pre-playing,whileplaying and post-playing stages in universities,its effects will be presented in an overall way: students can gain more communication skills in the mini society atmosphere,and the accuracy and fluency of their oral English will be improved. Although some factors may affect the effects of role-play use in oral English teaching in universities,with the better use of role-play in the future,the goal of oral English teaching will be realized.

Playing it cool Characterizing social play, bout termination, and candidate play signals of juvenile and infant Tibetan macaques (Macaca thibetana)

Play behaviors and signals during playful interactions with juvenile conspecifics are important for both the social and cognitive development of young animals. The social organization of a species can also influence juvenile social play. We examined the relationships among play behaviors, candidate play signals, and play bout termination in Tibetan macaques （Macaca thibetana） during juvenile and infant social play to characterize the species play style. As Tibetan macaques are despotic and live in groups with strict linear dominance hierarchies and infrequent reconciliation, we predicted that play would be at risk of misinterpretation by both the individuals engaged in the play bout and by those watching, possibly leading to injury of the players. Animals living in such societies might need to frequently and clearly signal playful intent to play partners and other group members to avoid aggressive outcomes. We gathered video data on 21 individually-identified juvenile and infant macaques （one month to five years of age） from the Valley of the Wild Monkeys, Mt. Huangshan, China. We used all-occurrence sampling to record play behaviors and candidate play signals based on an ethogram. We predicted that play groups would use multiple candidate play signals in a variety of contexts and in association with the number of audience members in proximity to the players and play bout length. In the 283 playful interactions we scored,juvenile and infant macaques used multiple body and facial candidate play signals. Our data showed that juvenile and infant Tibetan macaques use a versatile repertoire of play behaviors and signals to sustain play

Play therapy in children with autism:Its role,implications,and limitations

Play is a pleasurable physical or mental activity that enhances the child’s skills involving negotiation abilities,problem-solving,manual dexterity,sharing,decision-making,and working in a group.Play affects all the brain's areas,structures,and functions.Children with autism have adaptive behavior,adaptive response,and social interaction limitations.This review explores the different applications of play therapy in helping children with autism disorder.Play is usually significantly impaired in children with autism.Play therapy is mainly intended to help children to honor their unique mental abilities and developmental levels.The main aim of play therapy is to prevent or solve psychosocial difficulties and achieve optimal child-healthy growth and development.Play therapy helps children with autism to engage in play activities of their interest and choice to express themselves in the most comfortable ways.It changes their way of self-expression from unwanted behaviors to more non-injurious expressive behavior using toys or activities of their choice as their words.Play therapy also helps those children to experience feeling out various interaction styles.Every child with autism is unique and responds differently.Therefore,different types of intervention,like play therapy,could fit the differences in children with autism.Proper evaluation of the child is mandatory to evaluate which type fits the child more than the others.This narrative review revised the different types of play therapy that could fit children with autism in an evidence-based way.Despite weak evidence,play therapy still has potential benefits for patients and their families.

Prevalence of Pachinko-Pachislot Playing Disorder and the Characteristics of Individuals with the Disorder: Analysis of National Pachinko/Pachislot Survey Results

To understand the reality of gambling disorder caused by playing pachinko/pachislot, a national pachinko/pachislot survey was conducted. Based on the survey result, we examined the appearance ratio and the characteristics of individuals with a suspected pachinko-pachislot playing disorder. The analysis result indicated that approximately 0.4% of survey respondents were suspected to have the disorder. This appearance ratio was comparable to the prevalence of gambling disorder in the general population. Those who had a suspected disorder were likely to be divorced, and have no savings. Meanwhile, no distinctive characteristics were found in their gender, annual household income, or the highest educational attainment.

Examination of Screening of the Pachinko/Pachislot Playing Disorder Based on Gambling Disorder Scales

Pachinko and pachislot are unique forms of entertainment that dominate gambling activities in Japan. In this study, a web survey and interview were conducted in order to adjust three scales (DSM-5, SOGS, and PGSI) to pachinko/pachislot and explore an appropriate cutoff point for each of them. Using the assessment result in the interview as the outcome, the ROC curve of each scale was examined. The cutoff points were 4, 7, and 8 and the area under the curves (AUC) were 0.730, 0.783, and 0.724 for the DSM-5, SOGS, and PGSI, respectively. The study found that the type and situation of gambling influenced cutoff points in different ways depending on the questions asked in the scale.

Teaching Applied Piano Singing While Playing Based on Xindi Applied Piano Pedagogy:Taking Fujian Vocational College of Art as an Example

As known to all,China has witnessed remarkable development in addition to its effective implementation of the“double reduction”policy.Under such circumstance,the piano has drawn more interest and parental affection as a vital course that may improve students’all-round qualities.While piano education is gaining momentum,the country has raised the requirements for the piano teacher workforce in terms of their professional qualities.Under the background of promoting quality-oriented education nationwide,piano education in Chinese vocational colleges of art has garnered more attention.In contrast to applied piano instruction,which has received wide recognition and promotion,the traditional elite private teaching model targeted at nurturing pianists has more than ever failed to meet societal demands.The majority of graduates from vocational colleges of art seem to be unable to apply what they have learned.They are unable to compose accompaniment for simple songs,write piano music,provide piano accompaniment for singers,or sing while playing the piano.As a result,they fall short of living up to the expectations of piano teaching and meeting the needs of music teacher employment in primary and secondary schools.The development of“Xindi Applied Piano Pedagogy”can effectively address the aforementioned problems.As piano teachers,the authors experimented with Xindi Applied Piano Pedagogy to teach singing while playing the piano to first-year students at Fujian Vocational College of Art.A measurement table was used to measure the differences in various musical abilities of those students after the experiment,statistical analysis of the data was performed,and the preliminary results were obtained.The results showed that training in Applied Piano Singing while Playing led to a noticeable improvement in students’musical literacy,harmonic hearing,singing while playing beloved songs,and other abilities.Xindi Applied Piano Pedagogy is guided by the philosophy of talent cultivation,featuring“application,theories,and practice.”It can be tailored to different students,so that they can indeed apply what they have learned and enhance their practical and innovative capabilities.
