Application of the plasmatrix in alveolar ridge preservation / 口腔疾病防治

@#After tooth extraction, significant absorption occurs in the soft and hard tissues of the alveolar ridge. The goal of alveolar ridge preservation is to maintain the volume and shape of the alveolar ridge's soft and hard tissues as much as possible so as to provide suitable conditions for implant placement. Currently, there are challenges in classifying the socket for alveolar ridge preservation, such as the difficulty in directly guiding the selection of graft materials and clinical procedures and the insufficient space for particle xenograft maintenance, resulting in poor bone regeneration. Plasmatrix is an autologous blood derivative that effectively enhances tissue regeneration. This article introduced the characteristics of soft and hard tissue defects after tooth extraction and the primary applications of plasmatrix for alveolar ridge preservation (liquid plasmatrix, solid plasmatrix membrane/plug, and plasmatrix bone blocks) as well as the proposed methods for the reclassification of sockets for alveolar ridge preservation based on soft and hard tissue defects at the extraction site to facilitate the creation of clinical recommendations. The proposed classifications are as follows: Class I, extraction socket without bone defect, with or without soft tissue defect; Class Ⅱ, extraction socket with bone defect, both sides with bone wall defect less than 50%, with or without soft tissue defect; Class Ⅲ, extraction socket with bone tissue defect, at least one side with bone wall defect greater than 50%, with or without soft tissue defect. For the Class I socket, a solid plasmatrix membrane or plug is inserted, followed by injection of liquid plasmatrix, using a double-layer solid plasmatrix membrane for socket closure; for the ClassⅡ socket, plasmatrix bone blocks are inserted, followed by injection of liquid plasmatrix and secondary solidification, using absorbable collagen membrane and double-layer solid plasmatrix membrane for socket closure; for the ClassⅢ socket, tenting screws are used to maintain height, followed by implantation of plasmatrix bone blocks, injection of liquid plasmatrix and secondary solidification, using absorbable collagen membrane and double-layer solid plasmatrix membrane for socket closure. The aim of this article is to provide comprehensive knowledge of plasmatrix for oral clinicians to serve as a reference to simplify the clinical decision-making process and procedures for alveolar ridge preservation.

Effect of a brief training program on the knowledge of Filipino primary care providers in a rural and a remote setting: A before and after study

Background and Objective@#Primary care providers are key players in providing quality care to patients and advancing Universal Health Care (UHC). However, effective and quality healthcare delivery may be affected by inadequate knowledge and failure to adhere to evidence-based guidelines among providers. The Philippine Primary Care Studies (PPCS) is a five-year program that pilot tested interventions aimed at strengthening the primary care system in the country. Evidence-based training modules for healthcare providers were administered in Sorsogon and Bataan from the years 2018 to 2021. Module topics were selected based on common health conditions encountered by providers in rural and remote settings. This program aimed to evaluate the effectiveness of training in increasing provider knowledge.@*Methods@#A series of training workshops were conducted among 184 remote- and 210 rural-based primary care providers [nurses, midwives, barangay or village health workers (BHWs)]. They covered four modules: essential intrapartum and newborn care (EINC), integrated management of childhood illness (IMCI), non-communicable diseases (NCD), and geriatrics. A decision support system (UpToDate) was provided as a supplementary resource for all participants. We administered pre-tests and post-tests consisting of multiple-choice questions on common health conditions. Data was analyzed using paired one-tailed t-test, with an alpha of 0.05.@*Results@#The knowledge of nurses, midwives, and BHWs improved after the training workshops were conducted. The largest increase from pre-test to post-test scores were observed among the midwives, with a mean difference (MD) of 32.9% (95% CI 23.9 to 41.9) on the EINC module, MD of 25.0% (95% CI 16.6 to 33.4) in the geriatrics module, and MD of 13.5% (95% CI 6.9 to 20.1) in the NCDs module. The nurses had the greatest improvement in the IMCI module (MD 10.8%, 95% CI 2.5 to 19.1). The knowledge of BHWs improved in all participated modules, with greatest improvement in the NCD module (MD 9.0%, 95% CI 5.77 to 12.14). @*Conclusions@#Primary care workshops, even if conducted as single-sessions and on a short-term basis, are effective in improving short-term knowledge of providers. However, this may not translate to long-term knowledge and application in practice. Furthermore, comparisons across provider categories cannot be made as participant composition for each training workshop varied. Ultimately, this study shows enhancing provider knowledge and competence in primary care will therefore require regular and diverse learning interventions and access to clinical decision support tools.

Initial nipple damages in breastfeeding women: analysis of photographic images and clinical associations / Lesiones tempranas del pezón derivadas de la lactancia materna: análisis de imágenes fotográficas y asociaciones clínicas / Lesões mamilares precoces decorrentes da amamentação: análise de imagens fotográficas e associações clínicas

ABSTRACT Objective: to analyze the initial nipple damage degree by breastfeeding practice and to associate findings with clinical manifestations of breastfeeding women. Methods: a retrospective, cross-sectional study with primary data and photographic images database from two randomized clinical trials. Photographic images were analyzed by two independent evaluators using the Nipple Trauma Score. For analysis, the chi-square, Mann-Whitney tests and Kappa coefficient were applied. Results: 115 breastfeeding women and their respective 186 photographic images were analyzed. The degree of agreement of evaluators using the Nipple Trauma Score was 93.6%. The nipple pain score during breastfeeding was moderate and compromised more than 25% of the nipple surface area. Conclusions: assistance to breastfeeding women should prioritize nipple pain intensity instead of the nipple damage size.

Validación y Comparación de un Nuevo Método para Predecir el Ancho Mesiodistal de Caninos y Premolares no Erupcionados en una Población Chilena de la Región de Valparaíso, Chile

Uno de los principales problemas durante la dentición mixta es la determinación de la futura discrepancia entre tamaño dentario y el espacio disponible. Para predecir el ancho mesiodistal de los dientes permanentes no erupcionados se han introducido diferentes métodos de análisis. Objetivo: El propósito de este estudio fue comparar el método Tanaka-Johnston con una nueva ecuación de regresión para predecir el ancho mesiodistal de caninos y premolares permanentes no erupcionados en una población de la región de Valparaíso, Chile. Material y método: Este estudio fue realizado en la Facultad de Odontología de la Universidad de Valparaíso, desde octubre de 2022 a junio de 2023 (8 meses), la muestra estuvo compuesta por 202 modelos de estudio del departamento de ortodoncia (91 hombres y 111 mujeres) en el rango de edad de 11 -20 años. Resultados: Se demostró que el método elaborado por Lara-Sandoval presenta mayor fiabilidad respecto a las medidas mesiodistales reales de los pacientes (ICC 0,773 para maxilar y 0,762 para mandíbula), en comparación con el método de Tanaka-Johnston (ICC 0,665 para maxilar y 0,623 para mandíbula). No existen diferencias significativas entre los valores reales y el método de Lara-Sandoval. Conclusión: El método de Lara-Sandoval es mejor que el propuesto por Tanaka-Johnston para determinar el ancho mesiodistal de caninos y premolares para esta muestra. Es necesario validar este método en otras regiones del país para ser utilizado con mayor seguridad que el ya existente como método estándar nacional.

One of the main orthodontic problems in mixed dentition is the determination of future tooth and size arch discrepancy. In order to predict the mesiodistal widths of unerupted permanent teeth different methods of analyses have been introduced. The aim of this study is to compare the Tanaka-Johnston analysis with a new regressive equation to predict the mesiodistal width of unerupted permanent canines and premolars in a Chilean population sample, from Valparaíso region. This study was conducted at the Universidad de Valparaíso Dental Faculty, from october 2022 to june 2023 (8 months), and the sample comprised historical dental casts from 202 patients (91 boys and 111 girls) in the age range of 11-20 from the orthodontics department. All the patients are from the Valparaíso region, Chile. The results show that the predictions of the new regressive equation method are closer to the actual mesiodistal measurements of the patients (ICC 0,773 for maxilla and 0,762 for mandible), compared to the Tanaka- Johnston method (ICC 0,665 for maxilla and 0,623 for mandible). There are no significant differences between the real values and the Lara-Sandoval method. Lara-Sandoval method is better than the one proposed by Tanaka-Johnston to determine the mesiodistal width of canines and premolars in this sample population. It is necessary to validate this method in other regions of the country to be used with greater security than the ones that already exists as a national standard method.

THE NEW ERA OF DENTISTRY: MACHINE LEARNING AND ARTIFICIAL INTELLIGENCE

Innovative computer techniques are now being utilized not only in academic research but also in commercial dental practice, revolutionizing various areas of dentistry. This digitalization trend is driven by the increasing demands for treatment and diagnosis in the eld. Accurate diagnosis is crucial in dentistry, whether it be in orthodontics, maxillofacial surgery, periodontics, or prosthetics, as it forms the basis for creating effective treatment plans and restoring patients' oral health. While a specialist's expertise plays a vital role in diagnosis and treatment planning, it is susceptible to the inherent risks of human error, given the multifactorial nature of dental conditions. Consequently, there is growing interest in leveraging multi-parametric pattern recognition methods, including statistics, machine learning, and articial intelligence (AI), to enhance clinical decision-making. The introduction of clinical decision support systems (CDSS) and genetic algorithms (GAs) in dental research and clinical practice holds great promise for both healthcare professionals and patients. Extensive work has been undertaken to develop CDSS in dentistry, and this article reviews the latest advancements in this eld.

Analysis of Watson for oncology and clinicians� treatment recommendations for patients with breast cancer in Korea: A single center experience

Background: Various clinical applications have been attempted using artificial intelligence (AI) clinical decision support system (CDSS), and it has become a starting point for personalized cancer treatment. We aimed to identify the degree of agreement between the AI?CDSS, Watson for Oncology (WFO), and the clinician in treatment recommendations for Korean breast cancer patients and to provide guidelines for future improvement. Methods: One hundred and eighty?three breast cancer patients who underwent treatment at the Pusan National University Hospital between January 1, 2016 and May 31, 2017 were enrolled in this study. The concordance between WFO抯 and clinicians� treatment recommendations were examined according to various factors. Results: WFO gave the same treatment option recommendations as clinicians in 74 (40.4%) of the cases. According to the logistic regression, the difference in recommendation concordance between stage I and stage III was statistically significant (P = 0.004), and there was no difference among other factors. Conclusion: The concordance of treatment recommendations was low overall. However, this is largely attributable to the differences of medical insurance system and healthcare environment between the United States and Korea. In the future, region?specific features should be considered or reflected during the development of AI?CDSS.

Patients´ satisfaction concerning direct anterior dental restoration

Abstract The objective of this study was to observe patients' satisfaction with their in-service direct anterior dental restorations and to compare it with clinical evaluation using FDI (Federation Dental International) criteria. Patients scored their own anterior dental restorations regarding satisfaction (satisfactory /dissatisfactory). If dissatisfaction was mentioned, then, they would be interviewed about the complaint. In the same session, the dental restorations were clinically evaluated by two dentists using FDI criteria (1-5 score) concerning esthetic, functional, and biological domains. Descriptive statistics were used for frequencies of scores attributed by patients and clinicians. In order to compare patients' to clinicians' frequencies, the Chi-square test was applied (p ≤ 0.05). A total of 106 restorations were evaluated by patients and clinicians. Patients reported 52.8% of restorations satisfactory and 47.8% dissatisfactory. Overall, clinicians reported the same restorations as 82,3% satisfactory and 17,6% dissatisfactory. Patients' most frequent complaints referred to color, followed by anatomical form, fracture of material and retention, and approximal anatomical form. Comparing patients' satisfaction and dissatisfaction rates to clinicians' evaluation per criteria, there was no difference regarding esthetics. The frequency of dissatisfactory restorations by clinicians was significantly lower when functional and biological properties were compared with patients' opinions. Direct anterior dental restorations were more frequently reported as satisfactory by patients and clinicians, being the main complaints related to esthetic issues. When clinicians and patients' evaluations were compared, it was observed that the frequencies of satisfactory restoration by patients and clinicians were similar regarding esthetic properties, and significantly different regarding functional and biological properties.

Resumo O objetivo deste estudo foi observar a satisfação dos pacientes com suas restaurações dentárias anteriores diretas e compará-las com a avaliação clínica do dentista usando os critérios FDI (Federation Dental International). Os pacientes pontuaram suas restaurações dentárias (n=106) anteriores em relação à satisfação (satisfatória / insatisfatória). Quando insatisfatória, ele foi entrevistado sobre a queixa. Na mesma sessão, as restaurações dentárias foram avaliadas clinicamente por dois dentistas utilizando os critérios FDI (escore 1-5) quanto aos aspectos estéticos, funcionais e biológicos. Estatística descritiva foi usada para frequências de escores atribuídos por pacientes e clínicos. Para comparar as frequências dos pacientes e dos clínicos, foi aplicado o teste Qui-quadrado (p ≤ 0,05). Os pacientes relataram suas restaurações como 52,8% satisfatórias e 47,8% insatisfatórias. Os clínicos reportaram as mesmas restaurações, 82,3% satisfatória e 17,6% insatisfatória. As queixas mais frequentes dos pacientes referiam-se à cor, seguida da forma anatômica, fratura e retenção do material e forma anatômica proximal. Comparando os índices de satisfação e insatisfação dos pacientes com os clínicos, não houve diferença em relação à estética. A frequência de restaurações insatisfatórias por dentistas foi significativamente menor quando as propriedades funcionais e biológicas foram comparadas com as opiniões dos pacientes. As restaurações foram mais frequentemente relatadas como satisfatórias pelos pacientes, sendo as principais queixas relacionadas a questões estéticas. Quando as avaliações dos clínicos e dos pacientes foram comparadas, observou-se que as frequências de restaurações satisfatórias por pacientes e clínicos foram semelhantes em relação às propriedades estéticas e significativamente diferentes em relação às propriedades funcionais e biológicas.

Estratégias de ensino para desenvolvimento do pensamento crítico na graduação em enfermagem: overview de revisões sistemáticas / Educational strategies for development of clinical reasoning and critical thinking in nursing undergraduate students: overview protocol of systematic reviews

Resumo: O objetivo desta pesquisa foi sumarizar as evidências de revisões sistemáticas sobre a efetividade das estratégias de ensino para o desenvolvimento do raciocínio clínico ou pensamento crítico em estudantes da graduação em Enfermagem. Trata-se de uma overview de revisões sistemáticas, guiada pelas recomendações do Cochrane Handbook. O protocolo de pesquisa foi registrado na plataforma Prospero sob o número 187785, sendo este estudo inédito. O uso do protocolo possibilita a replicação ou atualização dessa overview. A pergunta de pesquisa foi: Quais as evidências de efetividade oriundas de revisões sistemáticas sobre as estratégias de ensino, isoladas, comparadas ou associadas, para o desenvolvimento do pensamento crítico dos estudantes de graduação em Enfermagem, em qualquer ambiente de aprendizagem? A busca por revisões Cochrane e não Cochrane foi realizada em oito bases de dados e bibliotecas, e na literatura cinzenta. Não houve restrições de idioma e ano de publicação. Foi recuperado um total de 13.936 estudos, com 6.620 participantes. Dois revisores independentes aplicaram os critérios de inclusão e exclusão, fizeram a extração dos dados e a análise de qualidade das revisões. Foram incluídas 11 revisões, com 65 estudos primários. As sínteses foram descritivas e por metanálises. A análise do risco de viés das revisões sistemáticas foi realizada por meio do instrumento ROBIS (Risk of Bias in Systematic Reviews); a qualidade metodológica foi avaliada pelo instrumento AMSTAR 2 (A MeaSurement Tool to Assess systematic Reviews); e a análise da força da evidência seguiu as recomendações do sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation). Quatorze estudos, com 1.350 participantes, forneceram evidências para metanálise. As evidências, ainda que classificadas como de certeza muito baixa, sugerem que a aprendizagem baseada em problemas e a simulação são estratégias de ensino que possibilitam o desenvolvimento do pensamento crítico em estudantes de graduação em enfermagem. Risco de viés, heterogeneidade elevada, número limitado de estudos, número de participantes reduzido contribuíram para o rebaixamento do nível de certeza das evidências. Recomenda-se que os docentes avaliem as características dos estudantes antes de optarem por uma ou outra estratégia de ensino, e ponderem o uso diversificado. São importantes a frequência e duração da aplicação das estratégias, uma vez que o desenvolvimento do pensamento crítico ocorre de forma processual e contínua. Recomenda-se aos pesquisadores que o relato seja aprimorado, incluindo informações relevantes, como dados estatísticos, características do estudante e do ambiente de ensino. O uso de ferramentas que orientem um relato de qualidade é indicado. No planejamento dos ensaios clínicos, é relevante prever e padronizar o tempo de exposição à estratégia de ensino e a quantidade de sessões; utilizar pelo menos duas escalas de mensuração do pensamento crítico e aplicá-las no mínimo antes e após a intervenção. Tais cuidados promovem robustez aos resultados. A contribuição social dessa tese inédita é a identificação de estratégias de ensino - aprendizagem baseada em problemas e simulação - eficazes para o desenvolvimento do pensamento crítico em estudantes de enfermagem, o que possibilita, consequentemente, aprimorar a qualificação dos futuros enfermeiros para a prática profissional segura e baseada em evidências.

Abstract: The aim of this study was to summarize evidence from systematic reviews on the effectiveness of teaching strategies for the development of clinical reasoning or critical thinking in undergraduate nursing students. This is an overview of systematic reviews guided by the Cochrane Handbook recommendations. The research protocol was registered on the Prospero platform under number 187785 and this study is unprecedented. The use of the protocol makes it possible to replicate or update this overview. The research question was: What is the evidence of effectiveness from systematic reviews on teaching strategies, isolated, compared or associated, for the development of critical thinking of undergraduate nursing students in any learning environment? The search for Cochrane and non-Cochrane reviews was performed in eight databases and libraries, and in the gray literature. There were no language and year of publication restrictions. A total of 13,936 studies with 6,620 participants were retrieved. Two independent reviewers applied inclusion and exclusion criteria and performed data extraction and quality analysis of the reviews. Eleven reviews with 65 primary studies were included. The syntheses were descriptive and by meta-analyses. Analysis of the risk of bias of systematic reviews was performed using the ROBIS instrument (Risk of Bias in Systematic Reviews); methodological quality was assessed using the AMSTAR 2 instrument (A MeaSurement Tool to Assess Systematic Reviews); and analysis of the strength of evidence followed the recommendations of the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). Fourteen studies of 1,350 participants provided evidence for meta-analysis. Despite the very low certainty of the evidence, findings suggest that the teaching strategies of problem-based learning and simulation enable the development of critical thinking in undergraduate nursing students. Risk of bias, high heterogeneity, limited number of studies, and reduced number of participants contributed to lower the level of certainty of the evidence. It is recommended that professors assess students' characteristics before choosing one or another teaching strategy and consider diversified use. The frequency and duration of the application of strategies is important, since the development of critical thinking occurs in a procedural and continuous way. It is recommended that researchers improve the report, including relevant information such as statistical data and characteristics of students and the teaching environment. The use of tools that guide a quality report is indicated. When planning clinical trials, it is important to predict and standardize the time of exposure to the teaching strategy and the number of sessions; use at least two clinical reasoning measurement scales and apply them at least before and after the intervention. These precautions bring robustness to the results. The social contribution of this unpublished thesis is the identification of effective teaching strategies for the development of critical thinking in nursing students, problem-based learning and simulation, thereby making it possible to improve the qualification of future nurses for a safe and evidence-based professional practice.

Concordance between referral and final diagnoses of pediatric patients with vascular malformations / Concordancia entre el diagnostico de referencia y final de pacientes pediátricos con malformaciones vasculares

Abstract Background: Vascular malformations (VaM) are a heterogeneous group of disorders resulting from the dysmorphogenesis of blood vessels. Although correct classification is relevant to providing adequate treatment according to evidence-based medicine, diagnostic terminology may be misused or need clarification. Methods: We conducted a retrospective study to measure agreement and concordance between referral and final confirmed diagnoses of 435 pediatric patients with VaM newly referred to the multidisciplinary Vascular Anomalies Clinic (VAC) using Fleiss kappa (κ) concordance analysis. Results: We found fair concordance between referral and confirmed diagnoses of VaM (κ 0.306, p < 0.001). Lymphatic malformations (LM) and VaM associated with other anomalies showed moderate diagnostic concordance (κ 0.593, p < 0.001 and κ 0.469, p < 0.001, respectively). Conclusions: Continuing medical education strategies are required to improve physician knowledge and diagnostic accuracy in patients with VaM.

Resumen Introducción: Las malformaciones vasculares (MVa) son un grupo heterogéneo de trastornos resultantes de la dismorfogénesis de los vasos sanguíneos. A pesar de que la correcta clasificación es relevante para brindar un adecuado tratamiento de acuerdo con la medicina basada en la evidencia, la terminología diagnóstica podría resultar confusa o utilizarse de manera inapropiada. Métodos: En este estudio retrospectivo se midieron el acuerdo y la concordancia entre los diagnósticos de referencia (o derivación) y los diagnósticos finales confirmados de 435 pacientes pediátricos con MVa recién remitidos a la Clínica de anomalías vasculares (CAV) multidisciplinaria, mediante el análisis de concordancia kappa de Fleiss (κ). Resultados: Se encontró una buena concordancia entre los diagnósticos de referencia (o derivación) y los diagnósticos confirmados de MVa (κ 0.306, p < 0.001). Las malformaciones linfáticas (LM) y las MVa asociadas con otras anomalías presentaron concordancias diagnósticas moderadas (κ 0.593, p < 0.001 y κ 0.469, p < 0.001, respectivamente). Conclusiones: Se requiere de estrategias de educación médica continua para mejorar el conocimiento de los médicos y la precisión diagnóstica de los pacientes con MVa.

Concordancia entre la prueba de puntuación de recurrencia de 21 genes y modelos clínico-patológicos predictivos en pacientes con cáncer de mama temprano en un centro oncológico en Colombia / Concordance between 21-gene recurrence score assay and clinicopathological predictive models in early-breast cancer patients cared for at a cancer center in Colombia

Resumen Introducción: La prueba genómica de recurrencia de 21 genes (PGR21) permite determinar la utilidad de la quimioterapia adyuvante en pacientes con cáncer de mama temprano luminal (CMTL). Se han desarrollado modelos predictivos adicionales, como las ecuaciones de Magee (EM), el modelo Predict (MP) y la puntuación del nomograma de la Universidad de Tennessee (NT). Objetivo: Evaluar la concordancia entre PGR21, EM, MP y NT. Métodos: Se incluyeron pacientes con CMTL unifocal y con resultados de PGR21, EM, MP y NT. Se efectuó subanálisis de mujeres mayores de 50 años. La concordancia se evaluó mediante índice kappa de Cohen (IK). Resultados: Se incluyeron 122 mujeres. La concordancia entre PGR21 y EM (IK = 0.35) y MP (IK = 0.24) fue aceptable (p < 0.001); entre PGR21 y NT fue inferior (IK = 0.16, p = 0.04). Se incluyeron 80 pacientes mayores de 50 años con datos suficientes para calcular los tres modelos. Se encontró concordancia entre la clasificación de bajo riesgo mediante PGR21 y los tres modelos combinados en 36/37 pacientes (valor predictivo negativo de 97.3 %). Conclusión: Se puede omitir la PGR21 en las mujeres mayores de 50 años con CMTL que se clasifica de bajo riesgo en los tres modelos predictivos.

Abstract Introduction: The genomic-based 21-gene recurrence score assay (21-GRSA) allows to determine the usefulness of adjuvant chemotherapy in patients with luminal-type early breast cancer (LTEBC). Additional predictive models have also been developed, such as Magee equations (ME), the Predict model (PM), and the Tennessee nomogram score (TNS). Objective: To evaluate the concordance between 21-GRSA, ME, PM and TNS. Methods: Patients with unifocal LTEBC and 21-GRSA, ME, PM and TNS results were included. A subgroup analysis of women older than 50 years was carried out. Concordance between the models and 21-GRSA was evaluated using Cohen's kappa index (KI). Results: One-hundred and twenty-two women were included. Concordance between 21-GRSA and ME (KI = 0.35) and PM (KI = 0.24) was fair (p < 0.001). Concordance between 21-GRSA and TNS was inferior (KI = 0.16, p = 0.04). Eighty patients older than 50 years with sufficient data to calculate all three predictive models were included. Concordance was found between the low-risk classification on 21-GRSA and all three combined models in 36/37 patients (negative predictive value of 97.3%). Conclusion: 21-GRSA can be omitted in women older than 50 years with LTEBC classified with low risk scores on all three predictive models.

Exploration on Shared Decision-making Mechanisms in Chinese Medicine Treatment / 中国医学伦理学

Traditional Chinese medicine(TCM) treatment models are rich and unique, including patient-led decision-making, doctor-led decision-making, and doctor-patient shared decision-making. However, doctor-led decision-making is more common. The connotation of TCM shared decision-making is rich, including not only the smooth flow of information and the encouragement and support of equal participation by patients, but also the discussions on various aspects of diet, exercise, emotions, daily life, physiology, psychology, society, and nature that affect health based on the unique holistic concept of TCM. Integrating "shared decision-making" into the treatment process of TCM can be divided into four steps according to the process of "diagnosis and treatment". TCM shared decision-making has advantages and limitations, requiring both doctors and patients to meet certain objective conditions, and there are also special situations in TCM treatment where shared decision-making cannot be applied. Multiple ways to enhance the decision-making ability of doctors and patients, scientific evaluation and matching treatment plans, development of decision-making aids, and smooth channels for information transmission can all enhance the shared decision-making ability of doctors and patients.

Clinical decision making of implant guidance methods guided by new classification of surgical area mouth ope-ning / 华西口腔医学杂志

When selecting implant guidance methods or judging whether the patient can be implanted, many doctors ignore or only use visual inspection to estimate a patient's mouth opening. This phenomenon often leads to failure to complete the implantation due to insufficient mouth opening or the deflection of the implant due to limited angle, resulting in the high incidence of corresponding complications. The main reason is that doctors lack accurate analysis and control of the overall geometric conditions of the intraoral surgical area, and three-dimensional position blocking of surgical instruments occurs during the operation. In the past, mouth opening was defined as the distance between the incisor edges of the upper and lower central incisors when the patient opens his mouth widely, and the implant area could be in any missing tooth position. When it is in the posterior tooth area, the specific measurement scheme of the mouth opening could not be simply equivalent to the previous measurement method in the anterior tooth area. However, how to measure quickly and conveniently the mouth opening of any surgical area to determine whether it could be implanted and meet the needs of the selected guidance method remains unclear. This paper introduces new concepts, establishes new classification and corresponding accurate measurement scheme of implant area, and establishes a decision tree of implant methods guided by the actually measured value. Results provide a quantitative basis for rational formulation and implementation of implant treatment.

Preliminary evaluation of the practicability of a clinical decision support system for diagnosis and treatment of thyroid cancer (CDSS-TC) / 中华内分泌外科杂志

Objective:To study the practical efficacy of the clinical decision support system for diagnosis and treatment of thyroid cancer (CDSS-TC) in assisting doctors to complete several diagnosis and treatment tasks, and to make a preliminary evaluation of its clinical practicability according to the test results.Methods:From Jan. 2022 to Mar. 2022, 90 patients with thyroid cancer who were admitted to the Head and Neck Surgery Department of Shaw Hospital affiliated to Zhejiang University were prospectively analyzed, and the average time spent in reading the pre-operative B-ultrasound report, as well as the individual fitness of the dose adjustment of eugenol in 70 patients with thyroid cancer after surgery. A retrospective analysis was made of the compliance of the basis of the "recommended scheme" and the deviation of the basis of the doctor’s "final scheme" for the preoperative surgery of 120 patients with thyroid cancer who were treated for the first time in the head and neck surgery of Shaw Hospital affiliated to Zhejiang University from Mar. 2021 to May. 2021. All cases were treated by pure artificial (group A) and CDSS-TC assisted (group B) , and the differences in organization were compared.Results:The average time for disposal of a single B-ultrasound report in Group B was much shorter than that in Group A ( P=5.600E-04) ; The number of patients with excellent grade and the total number of patients with excellent grade and qualified grade recommended by the doctor in group B were significantly higher than those in group A ( P=7.819E-20 and P=1.335E-18) ; The conformity rate of the basis of CDSS-TC "Recommended Scheme" ≥ 98%; The deviation rate of the basis for "final protocol" of doctors in group B was lower than that in group A ( P=0.059 for total resection or not, P=0.075 for lateral neck dissection or not) . Conclusions:CDSS-TC can accurately extract the disease-related source information in all the original examination/laboratory reports, and provide accurate decision-making suggestions through efficient correlation analysis. In view of the accurate and objective conclusions of its analysis, it can provide high-quality and all-link decision support for doctors’ clinical diagnosis and treatment, and is an ideal information work platform.

Clinical decision support system based on explainable artificial intelligence?brain of Mengchao liver disease / 中华消化外科杂志

In recent years, the artificial intelligence machine learning and deep learning technology have made leap progress. Using clinical decision support system for auxiliary diagnosis and treatment is the inevitable developing trend of wisdom medical. Clinicians tend to ignore the interpretability of models while pursuing its high accuracy, which leads to the lack of trust of users and hamper the application of clinical decision support system. From the perspective of explainable artificial intelligence, the authors make some preliminary exploration on the construction of clinical decision support system in the field of liver disease. While pursuing high accuracy of the model, the data governance techniques, intrinsic interpretability models, post-hoc visualization of complex models, design of human-computer interactions, providing knowledge map based on clinical guidelines and data sources are used to endow the system with interpretability.
