Methodological Evaluation of Advantages of Traditional Chinese Medicine Treatment of Sjögren's Syndrome / 中国实验方剂学杂志

Screening and evaluating the diseases responding specifically to traditional Chinese medicine （TCM） will help to highlight the advantages of TCM treatment， and the evaluation method should be standardized with consideration to the unique characteristics of the diseases. The incidence of Sjögren's Syndrome （SS） is increasing year by year， while the pathogenesis of this disease remains unclear. Modern therapies for this disease include biological agents and immunosuppressants， which generally have unsatisfactory efficacy. The TCM treatment of SS focuses on the harmony of the physical and mental health. The Rheumatology Branch of the China Association of Chinese Medicine organizes experts in TCM， Western medicine， and evidence-based medicine to form working groups. Delphi method and bibliometric method were used for analysis， and SS was selected as a disease responding specifically to TCM. Furthermore， the evaluation system was established for this disease， and the consensus regarding this disease was reached after seminar discussion. This paper summarized the whole process of the evaluation of the advantages of TCM treatment of SS. First， because TCM atomization is widely used in clinical practice and enriches TCM administration methods， this therapy is included after other non-drug therapies were taken as characteristic therapies. Second， the evaluation indicators of therapeutic effect should be determined with consideration to international acceptance and the current research status. Third， the expression method should be accurate， standardized， and objective， highlight the natural advantages of TCM， and avoid arbitrary extension. This paper provides a reference for clinicians to explore other diseases responding specifically to TCM.

Assessment of mouth breathing by Speech-Language Pathologists: an international Delphi consensus

ABSTRACT Purpose mouth breathing (MB) has detrimental effects on children's growth. Diagnosis of MB is possible through a multidisciplinary approach including Speech-Language Pathologist's (SLP) assessment; however, SLPs currently have little to no defined selection criteria to determine the awake and habitual breathing pattern. This study aims at identifying relevant criteria for the assessment of the habitual and awake breathing pattern of preschool children, and developing a grid that would help SLPs diagnose MB in their clinical practice. Methods A three-rounded online international Delphi process was conducted to achieve a consensus on the relevant items and their interpretation. Agreement was established through a Content Validity Ratio calculation. Based on the agreed items, we developed a grid through a scoring function. Results Observing the child at rest (i.e., time spent with an open/closed mouth and position of the tongue/lips) was considered the most important criterion. The experts also considered that observing the breathing pattern while chewing (open/closed mouth) and after swallowing (i.e., air intake and open/ closed mouth just after swallowing) should provide relevant but secondary information in decision-making. We were able to establish a clinical grid based on those criteria. Conclusion The Delphi procedure provided content-valid criteria and conditions of observation for the myofunctional SLP assessment of the awake and habitual breathing pattern in preschoolers. A clinical validation of the developed prototype grid should be conducted in preschool children to explore its effectiveness in the diagnosis of MB.

@#Introduction: Food and fitness levels are key factors required to maintain functional life. Hence, nutrition education is crucial in spreading awareness among Sports Science students. There is a paucity of plant-based nutrition knowledge and plantbased culinary skills for fitness locally. Therefore, this study aimed to develop a valid Plant-Based Culinary Nutrition Model (PBCNM) with nutrition knowledge and basic culinary skills to improve fitness among Sports Science students. Methods: This exploratory sequential mixed method study consisted of 2 phases. In Phase 1, a three-round modified Delphi method was conducted with 13 experts to generate a questionnaire that was validated. Lawshe worksheet determined the content validity ratio (CVR) for an item. Content validity index (CVI) for each section and the overall instrument was calculated. In Phase 2, quantitative data collection and analysis addressed the research questions and research gaps leading to model development. A total of 271 undergraduate Sports Science students at higher learning institutions were recruited as respondents. Results: In Phase 1, CVR of the overall survey was 1.0 and CVI was 0.834. Subsequently, the questionnaire was pilot tested for reliability and a Cronbach’s alpha score of 0.836 was obtained for the overall questionnaire. In Phase 2, the respondents’ mean and standard deviation score for the model’s components and needs was 4.21±0.73 for items 1-15. The integration of experts’ perspectives on the need of PBCNM for fitness and feedback from respondents resulted in the development of PBCNM. Conclusion: This study highlighted PBCNM as a helpful guideline for better fitness management.

Validity and reliability of online questionnaire on awareness, knowledge, attitude and self-efficacy (AKAS) on healthy eating for nutrition education and promotion

@#Introduction: This study entailed the process of developing an online questionnaire to determine awareness, knowledge, attitude and self-efficacy (AKAS) on healthy eating for nutrition education. Currently, there is no local validated questionnaire that can be used to assess AKAS on healthy eating among Filipino adults. Methods: The study developed the questionnaire based on theoretical frameworks and literature review. The draft questionnaire underwent three stages of development: (1) online modified Delphi technique composing of seven subject matter experts (SME) for content validity; (2) online cognitive debriefing with 32 participants (14 nutrition experts and 18 general public) for construct validity; and (3) online pre-testing with 35 participants (non-nutritionists) using test-retest method. Results: For first stage, the questionnaire contained 16 questions for awareness, 17 questions for knowledge, 17 questions for attitude, and 15 questions for self-efficacy. For second stage, significantly different scores (p-value<0.00) between nutritionist experts and general public were observed, showing good construct validity. For third stage, Spearman’s correlation of test-retest method was 0.640. The questionnaire yielded Cronbach’s alpha of 0.467 to 0.923 (round 1) and 0.435 to 0.923 (round 2). A second analysis was done to improve the internal consistency of the questionnaire. By combining two question categories (awareness and knowledge), the Cronbach’s alpha increased to 0.659 (round 2), and by deleting three questions in attitude category, the Cronbach’s alpha improved to 0.626 (round 2). Conclusion: The process used ensured the questionnaire’s validity and reliability. Hence, this online questionnaire may be adopted by parties interested in developing and assessing nutrition education.

Objective To establish a surveillance and early warning index system for schistosomiasis transmission risk along the middle and lower reaches of the Yangtze River basin, so as to provide insights into creation of a sensitive and highly efficient surveillance and early warning system for schistosomiasis. Methods National and international publications, documents, laws and regulations pertaining to schistosomiasis control were retrieved with keywords including schistosomiasis, surveillance, early warning and control interventions from 2008 to 2022, and a thematic panel discussion was held to preliminarily construct surveillance and early warning index system for schistosomiasis transmission risk along the middle and lower reaches of the Yangtze River basin. The index system was then comprehensively scored and screened using the Delphi method, and the weight of each index was determined using analytic hierarchy process and the modified proportional allocation method. In addition, the credibility of the Delphi method was evaluated using positive coefficient, authority coefficient, degree of concentration and degree of coordination of experts. Results Following two rounds of expert consultation, a surveillance and early warning index system for schistosomiasis transmission risk in endemic areas along the middle and lower reaches of the Yangtze River basin was preliminarily constructed, including 3 primary indicators, 9 secondary indicators and 41 tertiary indicators. The normalized weights of primary indicators epidemics, natural and social factors and comprehensive control were 0.639 8, 0.145 6 and 0.214 6, respectively, and among all secondary indicators, snail status (0.321 3) and schistosomiasis prevalence (0.318 5) had the highest combined weights, while social factors had the lowest combined weight (0.030 4). Of all tertiary indicators, human egg-positive rate (0.041 9), number of acute schistosomiasis cases (0.041 5), number of stool-positive bovine and sheep (0.041 1), and prevalence of Schistosoma japonicum in free-ranging livestock (0.041 1) had the highest combined weights. During two rounds of consultation, the positive coefficient of experts was both 100%, and the authority coefficient was both 0.9 and greater, while the coordination coefficients were 0.338 to 0.441 and 0.426 to 0.565 (χ2 = 22.875 to 216.524, both P values < 0.05). Conclusions The established surveillance and early warning index system for schistosomiasis transmission risk along the middle and lower reaches of the Yangtze River basin is of great scientific values and authority, which may provide insights into construction of the sensitive and highly efficient surveillance and early warning system for schistosomiasis in the context of low prevalence and low intensity of infection in China.

The correlation coefficient between the researcher's score and the respondents' self-assessment was 0.562. The five common factors extracted by factor analysis were consistent with the structure of the questionnaire， and the cumulative contribution of variance was 54.4%. Total questionnaire scores were moderately to highly correlated with each dimension score （0.409 to 0.699）. There was low correlation between the dimensions （-0.002 to 0.203）. Girls who had sought medical care had higher scores on the total questionnaire， category A， category B， cycle dimension， menstrual dimension， and dysmenorrhea/PMS dimension than girls who had not sought medical care （P<0.01）， and the difference between the two groups in menstrual volume dimension scores was not statistically significant. ConclusionThe self-assessment questionnaire for menstrual abnormalities developed in this study has acceptable reliability， good structure validity and response validity. It can provide a self-examination tool and medical consultation guidance for young women with abnormal menstruation.

Interpretation of the first edition of definition, diagnosis and treatment of oligometastatic oesophagogastric cancer: A Delphi consensus study in Europe / 中国胸心血管外科临床杂志

@#Local treatment improves the outcomes for oligometastatic disease, an intermediate state between locoregional and widespread disease. However, consensus about the definition, diagnosis and treatment of oligometastatic oesophagogastric cancer is lacking. The first edition "Definition, diagnosis and treatment of oligometastatic oesophagogastric cancer: A Delphi consensus study in Europe" was published on February 15, 2023 by 65 European medical specialists. In this article, the consensus will be interpreted to provide new idea for the diagnosis and treatment of oligometastatic oesophagogastric cancer for Chinese clinicians.

Optimization of nursing services for percutaneous coronary interventional therapy based on clinical nursing pathway / 中华医院管理杂志

Objective:To optimize the clinical nursing pathway, service program and evaluation parameters of percutaneous coronary intervention(PCI), for references for the cost accounting and compensation mechanism of nursing program in public hospitals.Methods:After literature analysis and group discussion, the initial templates were constructed for the PCI clinical nursing pathway, nursing service projects, and their evaluation parameters. 15 experts were consulted by two rounds of Delphi method to optimize PCI nursing path, nursing service items and their evaluation parameters (basic labor consumption, basic time consumption, technical difficulty and risk degree).Results:Two rounds of Delphi method finally determined the PCI clinical nursing path and 27 nursing service items, and adjusted the evaluation parameters of 10 nursing service items. The new projects for PCI clinical nursing services included adjustment and review of dual antiplatelet therapy plans, postoperative rehabilitation nursing, and key project verification. The three nursing service projects with the highest level of technical difficulty and risk were intravenous blood transfusion, gastric catheterization, and gastrointestinal decompression. The two items with the highest importance assigned were high pump assisted arterial/venous infusion (blood) and invasive continuous arterial blood pressure monitoring.Conclusions:The PCI clinical nursing pathway and nursing service project constructed in this study could closely integrate with clinical practice, highlight the integrated nursing service model, and reflect the labor value of nurses.
