Expert consensus on fundus photograph-based cardiovascular risk assessment using artificial intelligence technology / 中华内科杂志

Cardiovascular risk assessment is a basic tenet of the prevention of cardiovascular disease. Conventional risk assessment models require measurements of blood pressure, blood lipids, and other health-related information prior to assessment of risk via regression models. Compared with traditional approaches, fundus photograph-based cardiovascular risk assessment using artificial intelligence (AI) technology is novel, and has the advantages of immediacy, non-invasiveness, easy performance, and low cost. The Health Risk Assessment and Control Committee of the Chinese Preventive Medicine Association, in collaboration with the Chinese Society of Cardiology and the Society of Health Examination, invited multi-disciplinary experts to form a panel to develop the present consensus, which includes relevant theories, progress in research, and requirements for AI model development, as well as applicable scenarios, applicable subjects, assessment processes, and other issues associated with applying AI technology to assess cardiovascular risk based on fundus photographs. A consensus was reached after multiple careful discussions on the relevant research, and the needs of the health management industry in China and abroad, in order to guide the development and promotion of this new technology.

Expert consensus on vaccinations in adult patients with autoimmune rheumatic diseases in China (2023 Edition) / 中华预防医学杂志

Vaccination is one of the critical tools to prevent infections among individuals with autoimmune rheumatic diseases (ARDs), ultimately improving the quality of life and reducing mortality. The incorporation of vaccination strategies into clinical decision-making processes has been recognized as pivotal. However, the absence of clinical guidelines and consensus on vaccination for ARDs patients still persists in China. Drawing from existing clinical evidence, this expert consensus encompasses eight prevalent vaccines: Influenza vaccine, pneumococcal polysaccharide vaccine, COVID-19 vaccine, herpes zoster vaccine, human papillomavirus vaccine, hepatitis A vaccine, hepatitis B vaccine, and rabies virus vaccine. This initiative aims to furnish highly practical technical directives for vaccination personnel and rheumatologists, thereby fostering standardized vaccination practices to combat infectious diseases among adult ARDs patients in China.

Expert consensus on diagnosis and treatment of malignant pleural effusion caused by lung cancer / 中华肿瘤杂志

Malignant pleural effusion (MPE) can occur in nearly all types of malignant tumors, with lung cancer being the most prevalent cause. The presence of MPE indicates an advanced stage or distant spread of the tumor, significantly reducing the patient's life expectancy. Particularly, a substantial amount of pleural effusion can impede heart and lung function, impair blood oxygen perfusion levels in the body, and greatly diminish patients' quality of life. Even when systemic treatment has alleviated the primary lung tumor in some patients, effective control over MPE remains challenging and impacts clinical outcomes. Therefore, it is crucial to implement measures for reducing or managing MPE while ensuring standardized treatment for lung cancer. In recent years, significant advancements have been made in diagnosing and treating lung cancer complicated by MPE through extensive basic and clinical research. Based on existing evidence and China's clinical practice experience, relevant experts from the China Association of Health Promotion and Education and Cancer Rehabilitation and Palliative Treatment Professional Committee of China Anti-Cancer Association (CRPC) have summarized key aspects related to diagnosis and treatment consensus opinions for lung cancer complicated by MPE. This aims to establish standardized procedures that will serve as a reference for doctors' clinical practice.

Chinese expert consensus on the diagnosis and treatment for lateral lymph node metastasis of rectal cancer (2024 edition) / 中华胃肠外科杂志

Currently, there is still controversy regarding the diagnosis and treatment of LLNM in rectal cancer. This consensus, based on the "Chinese Consensus on Diagnosis and Treatment of Lateral Lymph Node Metastasis in Rectal Cancer (2019 edition)," incorporates the latest domestic and international research findings and revises aspects related to the diagnosis, treatment strategies, follow-up, and management of recurrence of LLNM in rectal cancer. A total of 42 domestic colorectal cancer experts participated in this consensus. It proposes 18 consensus statements on the diagnosis and treatment of LLNM, using the evaluation criteria of the U.S. Preventive Services Task Force for grading recommendations. The aim is to standardize further the diagnostic criteria and treatment strategies for LLNM in rectal cancer. Unresolved issues in this consensus require further clinical practice and active engagement in high-quality clinical research to explore and address them progressively.

Ultra-processed food consumption and nutritional status in Uruguayan and Brazilian children between three to five years / Consumo de alimentos ultraprocesados y estado nutricional en niños de tres a cinco años uruguayos y brasileños

Introduction. There is growing consensus globally that the consumption of ultra- processed food (UPF) can negatively affect the nutritional status of children. Objective. The present study aims to evaluate associations between the consumption of UPF and the nutritional status in a sample of Uruguayan and Brazilian preschoolers belonging to two studies: the ENDIS Study and the Pelotas 2015 Birth Cohort. Materials and methods. We conducted a cross-sectional analysis. The main outcome measure was obesity defined as BMI for age and sex ≥ +3 z-scores. The score of UPF consumption was the main exposure measured. Each positive answer of habitual intake was added up to create a UPF score ranging from zero to six or more UPF. Crude and adjusted logistic regressions were performed for the associations between UPF consumption and nutritional status in preschoolers. Results. The final sample consisted of 8,687 preschool children, 50.8% belonging to the Uruguayan study, while the remaining 49.2% belonged to the Brazilian study. Nearly 5% of the sample of young children were obese. We didn't observe a relationship between the score of UPF consumption and obesity, the odds ratio (OR) was 1.04 (95% CI, 1.00­1.09). Adjustments resulted in modest attenuation of the relationship and a lack of statistical significance. However, in children under 48 months, the score of UPF consumption was directly associated with childhood obesity. Conclusions. Results suggest that higher consumption of UPF is associated with obesity in Uruguayan and Brazilian preschool children under 4 years of age. These findings suggest that actions to reduce ultra- processed food consumption could lead to diminish obesity patterns and bring important public health benefits(AU)

Introducción. Existe creciente consenso a nivel mundial de que el consumo de alimentos ultraprocesados puede afectar negativamente el estado nutricional de los niños. Objetivo. El presente estudio tiene como objetivo evaluar asociaciones entre el consumo de ultraprocesados y el estado nutricional en una muestra de preescolares uruguayos y brasileños pertenecientes a dos estudios: el Estudio ENDIS y la Cohorte de Nacimiento de Pelotas 2015. Materiales y métodos. Se realizó un análisis transversal. La principal medida de resultado fue la obesidad definida como el IMC/edad y sexo ≥ +3 puntuaciones z. La puntuación del consumo de ultraprocesados fue la principal exposición. Cada respuesta positiva de la ingesta habitual se sumó para crear una puntuación de ultraprocesados que oscilaba entre cero y seis o más. Se realizaron regresiones logísticas crudas y ajustadas. Resultados. La muestra final estuvo constituida por 8.687 niños, de los cuales el 50,8% pertenecía al estudio uruguayo, mientras que el 49,2% restante pertenecía al estudio brasileño. Casi el 5% de la muestra de niños pequeños eran obesos. No observamos relación entre la puntuación del consumo de ultraprocesados y la obesidad, el odds ratio (OR) fue de 1,04 (IC 95%, 1,00-1,09). Los ajustes dieron lugar a modesta atenuación de la relación y falta de significación estadística. Sin embargo, en menores de 48 meses la puntuación de consumo de ultraprocesados se asoció directamente con la obesidad infantil. Conclusiones. Los resultados sugieren que un mayor consumo de ultraprocesados se asocia con obesidad en prescolares uruguayos y brasileños menores de 4 años. Estos hallazgos sugieren que las acciones para reducir el consumo de alimentos ultraprocesados podrían conducir a una disminución de los patrones de obesidad y traer importantes beneficios para la salud pública(AU)

Consenso SOCHOG/SOCHUMB: utilizar en Chile la curva estándar OMS ultrasonográfica de crecimiento fetal / SOCHOG/SOCHUMB consensus: OMS fetal ultrasound curve is the standard curve for ultrasound growth assessment to use in Chile

Síntesis de evidencia. Covid persistente / Evidence synthesis. persistent covid

El término Covid persistente fue utilizado por primera vez por la Dra. Elisa Perego, como un hashtag de Twitter en mayo de 2020. Describía su propia experiencia de una condición cíclica multifásica, que difería de la evolución clínica característica de Covid-19 tanto en sintomatología como en tiempo. El término Covid persistente o 'Long Covid' tiene varios nombres dependiendo de la literatura consultada: 'secuelas post-agudas de Covid-19', 'Covid¬-19 en curso', 'síndrome crónico de Covid', 'Covid de larga distancia' (Long haulers) y 'condición post-Covid-19', esta última es la utilizada por la Organización Mundial de la Salud (OMS) y todas son consideradas por los Centros para el Control y la Prevención de Enfermedades (CDC) como 'condiciones pos Covid. Aún no existe consenso en cuanto al reconocimiento de Covid persistente como entidad clínica, así como tampoco en cuanto a su nombre y criterios diagnósticos. Sin embargo, dada la alta prevalencia de la sintomatología a la que se le asocia, es imperativo que los servicios y las políticas de salud prioricen su atención. A la vez, es necesario efectuar estudios a futuro para identificar en detalle los diferentes subtipos de Covid persistente y, permitir así, su atención médica estratificada sin que los servicios de salud no se vean abrumados.

The term persistent Covid was used for the first time by Dr. Elisa Perego, as a Twitter hashtag in May 2020. It described her own experience of a multiphasic cyclical condition, which differed from the characteristic clinical evolution of Covid-19 both in symptomatology as in time The term persistent Covid or 'Long Covid' has several names depending on the literature consulted: 'post-acute sequelae of Covid-19', 'Covid¬-19 in progress', 'chronic Covid syndrome', 'Long-distance Covid ' (Long haulers) and 'post-Covid-19 condition', the latter is the one used by the World Health Organization (WHO) and all are considered by the Centers for Disease Control and Prevention (CDC) as ' post covid conditions. There is still no consensus regarding the recognition of persistent Covid as a clinical entity, nor regarding its name and diagnostic criteria. However, given the high prevalence of the symptoms to which it is associated, it is imperative that health services and policies prioritize care. At the same time, it is necessary to carry out future studies to identify in detail the different subtypes of persistent Covid and, thus, allow their stratified medical care without the health services being overwhelmed.

Comparison of diagnosis frequency between versions of the European Consensus on Sarcopenia: a cross-sectional study / Comparação da frequência de diagnóstico entre as versões do Consenso Europeu sobre Sarcopenia: um estudo transversal

OBJECTIVE: To compare sarcopenia diagnosis according to 2 versions of the European Consensus on Sarcopenia (EWGSOP and EWGSOP2) in a sample of older adults. METHOD: This cross-sectional study included 82 community-dwelling older people from Porto Alegre, Brazil. The patients were assessed by trained professionals and were classified according to the criteria of the 2 versions of the consensus to show the differences between the classification models. RESULTS: The participants performed the Timed Up and Go test in < 7.21 seconds. On average, their performance on the 6-meter walk test was above the predicted value. Only 3 patients had a gait speed < 0.8 m/s. Handgrip strength was, on average, the predicted percentage. In the Short Physical Performance Battery, the scores of a few were intermediate but most were high. According to EWGSOP criteria, 92.18% were non-sarcopenic and 7.81% had severe sarcopenia, while according to EWGSOP2 criteria, 98.43% were non-sarcopenic, 1.56% were sarcopenic, and none had severe sarcopenia. The rate of sarcopenia diagnosis, which was 8.53% according to EWGSOP criteria, reduced to 3.65% according to EWGSOP2 criteria and the new cut-off points (p = 0.034). CONCLUSION: Although our sample was small, the reduction was significant, indicating that the change in criteria, even with lower cut-off points, reduced the probability of early diagnosis

OBJETIVO: Comparar a aplicação dos critérios e orientações das duas versões do Consenso Europeu sobre Sarcopenia (EWGSOP e EWGSOP2) para o diagnóstico e classificação, numa amostra de idosos residentes na comunidade. METODOLOGIA: Estudo transversal, com 82 idosos residentes na comunidade da cidade de Porto Alegre. Os pacientes foram avaliados por profissionais treinados e classificados segundo os critérios dos dois consensos para mostrar as diferenças entre os dois modelos de classificação.RESULTADOS: Em testes físicos como o timed up and go, a amostra realizou o teste em menos de 7,21 segundos. Em média, os idosos conseguiram caminhar no teste de caminhada de 6 metros mais do que a percentagem prevista para esse público. Apenas três pacientes apresentaram velocidade de caminhada inferior a 0,8 m/s. Na avaliação de força, os idosos conseguiram atingir, em média, o percentual previsto. No Short Physical Performance Battery, poucos tiveram desempenho intermediário. A maioria teve desempenho alto. Quando avaliados pelo EWGSOP, 92,18% eram não sarcopênicos, enquanto 7,81% eram sarcopênicos severos; e, quando avaliados pelo EWGSOP2, 98,43% eram não sarcopênicos, 1,56% sarcopênico e nenhum sarcopênico severo. A aplicação dos critérios EWGSOP2 e novos pontos de corte reduziram a capacidade de diagnóstico de sarcopenia na amostra de 8,53 para 3,65% (p = 0,034).CONCLUSÃO: Embora a amostra seja pequena, a redução é significativa e expressa que a mudança de critério, mesmo utilizando pontos de corte mais baixos para a amostra em análise, trouxe impacto no sentido de não diagnosticar precocemente

Actualización del consenso chileno SOCHINEP-SER para el manejo de las sibilancias recurrentes del preescolar / Update of the chilean consensus SOCHINEP-SER for the management of recurrent wheezing in preschool children

Las sibilancias recurrentes del preescolar son un problema prevalente. 50% de todos los niños tiene al menos un episodio de sibilancias en los primeros 6 años. Sin embargo, solo 4% de los menores de 4 años tiene diagnóstico de asma. Por este motivo es fundamental realizar una adecuada anamnesis y examen físico tendientes a descartar causas secundarias, lo que debe ser complementado con exámenes de laboratorio de acuerdo con la orientación clínica. En la actualidad se recomienda indicar tratamiento de mantención con corticoides inhalados en aquellos niños que tengan episodios repetidos de obstrucción bronquial y que tengan una alta probabilidad de respuesta favorable a esta terapia. Se ha demostrado que aquellos pacientes que tienen un recuento de eosinófilos en sangre > 300 células por mm3 o aquellos que presentan una prueba cutánea positiva o IgE específicas positivas para alergenos inhalados responderán adecuadamente al tratamiento con esteroides inhalados.

Recurrent wheezing in preschoolers has a high prevalence. 50% of all children have at least one wheezing episode in the first six years of life. However, only 4% of children under four years of age are diagnosed with asthma. Therefore it is essential to carry out an adequate medical history and physical examination to rule out secondary causes, which must be complemented with laboratory tests in accordance with clinical guidance. It is recommended to indicate maintenance treatment with inhaled corticosteroids to those children who have repeated episodes of wheezing and who have a high probability of a good response to this therapy. It has been demonstrated that those patients who have blood eosinophil count > 300 cells per mm3 or those who have a positive skin test or positive specific IgE for inhaled allergens will have a good response to inhaled corticosteroids.

Expert consensus on digital guided therapy for endodontic diseases / 国际口腔科学杂志·英文版

Digital guided therapy (DGT) has been advocated as a contemporary computer-aided technique for treating endodontic diseases in recent decades. The concept of DGT for endodontic diseases is categorized into static guided endodontics (SGE), necessitating a meticulously designed template, and dynamic guided endodontics (DGE), which utilizes an optical triangulation tracking system. Based on cone-beam computed tomography (CBCT) images superimposed with or without oral scan (OS) data, a virtual template is crafted through software and subsequently translated into a 3-dimensional (3D) printing for SGE, while the system guides the drilling path with a real-time navigation in DGE. DGT was reported to resolve a series of challenging endodontic cases, including teeth with pulp obliteration, teeth with anatomical abnormalities, teeth requiring retreatment, posterior teeth needing endodontic microsurgery, and tooth autotransplantation. Case reports and basic researches all demonstrate that DGT stand as a precise, time-saving, and minimally invasive approach in contrast to conventional freehand method. This expert consensus mainly introduces the case selection, general workflow, evaluation, and impact factor of DGT, which could provide an alternative working strategy in endodontic treatment.

Experts consensus on the procedure of dental operative microscope in endodontics and operative dentistry / 国际口腔科学杂志·英文版

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Molecular dynamics simulation reveals DNA-specific recognition mechanism via c-Myb in pseudo-palindromic consensus of mim-1 promoter / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

This study aims to gain insight into the DNA-specific recognition mechanism of c-Myb transcription factor during the regulation of cell early differentiation and proliferation. Therefore, we chose the chicken myeloid gene, mitochondrial import protein 1 (mim-1), as a target to study the binding specificity between potential dual-Myb-binding sites. The c-Myb-binding site in mim-1 is a pseudo-palindromic sequence AACGGTT, which contains two AACNG consensuses. Simulation studies in different biological scenarios revealed that c-Myb binding with mim-1 in the forward strand (complex F) ismore stable than that inthereverse strand (complex R). The principal component analysis (PCA) dynamics trajectory analyses suggested an opening motion of the recognition helices of R2 and R3 (R2R3), resulting in the dissociation of DNA from c-Myb in complex R at 330 K, triggered by the reduced electrostatic potential on the surface of R2R3. Furthermore, the DNA confirmation and hydrogen-bond interaction analyses indicated that the major groove width of DNA increased in complex R, which affected on the hydrogen-bond formation ability between R2R3 and DNA, and directly resulted in the dissociation of DNA from R2R3. The steered molecular dynamics (SMD) simulation studies also suggested that the electrostatic potential, major groove width, and hydrogen bonds made major contribution to the DNA‍-specific recognition. In vitro trials confirmed the simulation results that c-Myb specifically bound to mim-1 in the forward strand. This study indicates that the three-dimensional (3D) structure features play an important role in the DNA-specific recognition mechanism by c-Myb besides the AACNG consensuses, which is beneficial to understanding the cell early differentiation and proliferation regulated by c-Myb, as well as the prediction of novel c-Myb-binding motifs in tumorigenesis.
