This editorial comments on an article recently published by López del Hoyo et al.The metaverse,hailed as"the successor to the mobile Internet",is undoubtedly one of the most fashionable terms in recent years.Although metaverse development is a complex and multifaceted evolutionary process influenced by many factors,it is almost certain that it will significantly impact our lives,including mental health services.Like any other technological advancements,the metaverse era presents a double-edged sword for mental health work,which must clearly understand the needs and transformations of its target audience.In this editorial,our primary focus is to contemplate potential new needs and transformation in mental health work during the metaverse era from the pers-pective of multimodal emotion recognition. 展开更多

Background: The most prevalent non-communicable disease worldwide is oral health-related disease, with dental caries and periodontal conditions being common. Oral health status significantly impacts overall health and quality of life. Barriers to dental care affect children with special needs. This study evaluates the oral health status and treatment requirements of people with special needs. Methodology: This descriptive cross-sectional study in Kumasi, Ghana examined oral health status among people, 121 children with special needs over two months, in June-July 2022. Dental caries, periodontal changes, malocclusion, and trauma were assessed. The data was analyzed using SPSS 20.0. Results: The oral health status among people with special needs in this study was generally moderate, with a range from very good to very poor. The prevalence of dental caries was 37%, with a mean DMFT score of 2.82. Periodontal health showed unsatisfactory indicators such as mobile teeth, poor gingival health, high plaque scores, and the presence of halitosis. Conclusion: This descriptive study aimed to provide baseline data on the oral health status of special needs students in Kumasi, addressing the lack of knowledge in this area. It highlighted the importance of dental care in maintaining good oral health and overall well-being in individuals with special needs. Coordinated efforts by dental professionals are needed to provide dental health education and preventive interventions for these children. 展开更多

Background:There are increasing concerns about the mental health needs of international students.Previous studies report that international students experience additional challenges and higher levels of stress compared to domestic students.This integrative review aimed to identify perceived stressors,coping strategies and factors that contributed to accessing mental health services of international students.Methods:A systematic search was performed between January 2010 and December 2023 using PubMed,CINAHL,ProQuest,the Cochrane Library,Scopus and PsycINFO databases.A manual search was also performed that included reference lists of included articles;data was extracted and reviewed by three reviewers.A total of 21 studies were included in this review with a total of 4442 international students recruited,with ages between 17 to 43 years.Nineteen studies reported international students’gender,there were more females(n=2205)than males(n=1022).Ethnicity was reported in 18 studies.They included Asia,Europe,Latin America,North America,South America,Africa,the Middle East and Pacific Islands.This review adopted Whittemore and Knafl’s five-stage approach,with specific steps for problem identification,literature search,data evaluation,data analysis,and presentation.Results:The Health Belief Model was used to explain relationships among independent and dependent variables and guide the findings of this review.Three identified progressive themes emerged including Theme 1:understanding cultural variations with perceived stress;Theme 2:coping strategies in dealing with stress and challenges in the new environment;and Theme 3:perceived threats and stress affecting how international students perceived barriers and benefits to access counselling support services and mental health services.This integrative review presents an overview of mental health needs and factors contributing to the mental health and well-being of international students via the inclusion of studies with different designs,providing an in-depth understanding of the study phenomenon.The findings of this review may help university health providers,mental health professionals,academic institutions and policymakers better understand the multifaceted needs of international students.Conclusion:This review demonstrates the importance of increased cross-cultural interactions between international students and domestic student counterparts to enhance belongingness and connection to host countries.This may facilitate adaptation to new living and learning environments.It is crucial academic institutions offer programs that can be effectively implemented and sustained to meet the unmet mental health needs of international students.University orientation programs,student counselling and health services may integrate cultural events,social support groups,leadership programs and resilience models of acculturation to promote mental health and well-being among international students.While these studies show promising results,there is a need for further robust evaluative studies to develop culturally sensitive mental health promotion programs for international students. 展开更多

This study aims to understand the in-service training needs,training transfer,and training effectiveness of teachers in local normal universities in China,while also proposing a continuous professional development plan for teachers.Descriptive research methods were employed,with questionnaires serving as the primary data collection tool.The survey revealed that the educational background of teachers in local normal universities is characterized by an unreasonable distribution of academic qualifications,with a shortage of teachers holding postgraduate and higher degrees.Additionally,the training effectiveness for female teachers was found to be lower than that of male teachers.There is a lack of personalization in training needs,which tends to be more generalized.The transfer effect of training is moderate,and there is a need for further enhancement at the behavioral level of training effectiveness.A continuous professional development plan for teachers has been formulated to improve training effectiveness and promote professional development. 展开更多

The design of diabetes inpatient educational preparation should be based on the needs of the nurses involved in terms of skills in this area. The objective of this qualitative study is to identify the preparatory needs of nurses working in the medical and surgical units of a Lebanese hospital in terms of Survival Skills Education for Hospitalized Diabetic Patients (SSEHDP). Method: The focus group method is used for data collection using a semi-structured interview guide. The needs expressed by the thirty-two participating nurses were classified into categories of the competency framework for providing self-management education to diabetic patients proposed by the American Diabetes Association. Results: By focusing on the themes of an SSEHDP, a list of preparatory needs was drawn up. The needs identified and analyzed are then translated into general and specific learning objectives for educational preparation. Conclusion: The needs analysis is only the first step in a work that will ideally continue into the implementation and eventual evaluation of an educational program developed to help nurses acquire skills in the education of diabetic patients. 展开更多

More information is required. Are students not motivated to keep improving their English; what obstacles do they face? The English language issues facing international students from China at one University are explored through a survey and focus groups. It is observed that a lack of motivation is not the key factor. Rather one core problem is the very difficult demands of acculturation within a short time frame which would enable confidence for the students to continue to engage with other English speaking students. When faced with such immediate and hard to achieve acculturation, many retreat to their language groups. In the academic context, support for the transition to discipline based academic genres is double difficult as the time frame for second language learners is longer, but performance requirements are more immediate. Many first language students also have difficulties in this area, but have the easier language path to mastery. The study draws usefully on a comparison made with students studying English in China. 展开更多
