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

Lateral lymph node metastasis (LLNM) is common in mid-low rectal cancer and is also a major cause of postoperative local recurrence. 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.

IgG4 is a subclass of IgG. Elevated serum IgG4 levels are an important serological feature of IgG4 related diseases and serve as a serological marker for assessing disease activity and severity. The harmonization of IgG4 detection is crucial for its clinical application. National Clinical Research Center for Dermatologic and Immunologic Diseases (Peking Union Medical College Hospital), Experimental Diagnosis Research Committee, Rheumatology and Immunology Physicians Committee of Chinese Medical Doctor Association, Autoantibodies Detection Committee, and Chinese Rheumatism Data Center have organized clinical and laboratory experts to draft this consensus, aiming to standardize IgG4 detection and provide guideline for clinician and laboratory experts to appropriate utility and interpret IgG4 results in China.

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.

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

La Sociedad Chilena de Obstetricia y Ginecología (SOCHOG) y la Sociedad Chilena de Ultrasonido en Medicina y Biología (SOCHUMB) convocaron a un comité de expertos en el tema de ultrasonido y crecimiento fetal con el fin de proponer utilizar la curva fetal que mejor se adapte a la población chilena. Luego de la discusión, al no contar con curvas chilenas de crecimiento fetal, se concluye proponer que la curva estándar de la Organización Mundial de la Salud (OMS) sería la indicada dada la calidad de su metodología y por ser multicéntrica.

The Chilean Society of Obstetrics and Gynecology (SOCHOG) and the Chilean Society of Ultrasound in Medicine and Biology (SOCHUMB) have convened a committee of experts on the subject of ultrasound and fetal growth in order to propose using the fetal curve that best adapts to the Chilean population. After the discussion, since there are no Chilean fetal growth curves, it is concluded that the World Health Organization (WHO) standard curve would be the one to use given the quality of its methodology and the fact that it is multicentric.

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.

Chinese expert consensus of albumin-bound paclitaxel in the treatment of breast cancer / 中华肿瘤杂志

Breast cancer is the most common malignant tumor of women, which seriously threatens women's health. Albumin-bound paclitaxel is the basic chemotherapy drug for breast cancer treatment. We can promote reasonable clinical medication and improve patients' quality of life by standardizing chemotherapy plans, rationally optimizing treatment strategy and managing adverse reactions of albumin-bound paclitaxel. In order to standardize the clinical application of albumin-bound paclitaxel in breast cancer, Chinese Medical Doctor Association Oncologist Branch Breast Cancer Group and International Medical Exchange Branch of China Anti-Cancer Association consulted guidelines and the latest evidence-based evidences and formulated Chinese expert consensus of albumin-bound paclitaxel in the treatment of breast cancer to provide reference for clinical diagnosis and treatment of breast cancer. The consensus mainly introduces the clinical application strategies and evidence-based evidences of albumin-bound paclitaxel in advanced therapy, neoadjuvant therapy and adjuvant therapy of breast cancer. Among them, the regimens containing albumin-bound paclitaxel are the better recommended regimens for preoperative neoadjuvant and advanced rescue therapy of breast cancer. However, there is little evidence in adjuvant therapy, so it is recommended to use albumin-bound paclitaxel cautiously. We also invited breast cancer clinical experts to vote on some controversial issues, including but not limited to the usage and dosage of albumin-bound paclitaxel, combined medication and management of peripheral neuropathy, and formed consensus recommendations for the reference of breast cancer clinical workers.

By meticulously reviewing relevant literature from both domestic and international sources and integrating the clinical expertise of the panel of experts, the committee has formulated 20 recommendations. These recommendations aim to establish standardized processes for surgical diagnosis and treatment of STC, ultimately elevating the overall diagnostic and therapeutic standards for STC across China.

Chinese expert consensus on the treatment of hemorrhoids by injection(2023 edition) / 中华胃肠外科杂志

Hemorrhoids is a common anorectal disease, usually occurring in middle-aged people aged 25-65 years old, clinical bleeding, swelling, prolapse, pain, itching and anal discomfort, and repeatedly attacks and aggravated gradually, seriously affecting the quality of life of patients. The treatment of hemorrhoids includes conservative, injection, ligation, and various surgical procedures. Injection therapy with a history of more than 150 years is simple to operate, easy to popularize and apply in grass-roots units, causes less intraoperative bleeding and fewer complications, and has reliable efficacy. As a result, it is favored by clinicians and patients. The injection treatment of hemorrhoids has been mentioned in various hemorrhoid treatment guidelines and consensus at home and abroad, but there is no special expert consensus for reference. Led by the Anorectal Physicians Branch of the Chinese Medical Doctor Association and the Colorectal Surgery Group of the Surgery Branch of the Chinese Medical Association, experts in related fields in China were invited to review the latest evidence-based medical evidence at home and abroad and conducted evidence quality assessment and recommendation strength classification according to the GRADE system. This paper attempts to make detailed recommendations on the types and application methods of the preparations commonly used in the injection treatment of hemorrhoids at home and abroad, and form the Chinese Expert Consensus on the Treatment of hemorrhoids by anal injection (2023 edition), aiming to guide the reasonable selection of drugs and dosage forms for hemorrhoidal injection treatment, and to provide reference for standardizing the use of different drugs and dosage forms, so as to improve the effectiveness and safety of clinical application of hemorrhoidal injection treatment.

Chinese expert consensus on colonic and anorectal manometry (2023 edition) / 中华胃肠外科杂志

Colonic and anorectal manometry includes anorectal manometry and colonic manometry. Anorectal manometry is a common method to evaluate anorectal function, which can objectively reflect the pathological and physiological abnormalities of outlet obstructive constipation and fecal incontinence, as well as the impact of anorectal surgery on continence. Colonic manometry is a new type of colon motility detection method developed in recent years. It can record the peristalsis and contraction of the whole colon through a pressure measuring catheter, which helps physicians further evaluate various colonic diseases. However, various factors such as testing equipment, operating standards, and evaluation parameters are difficult to unify. There is no consensus on the operation and interpretation of colorectal anal pressure measurement. Under the guidance of the Anorectal Branch of Chinese Medical Doctor Association, in collaboration with Clinical Guidelines Committee, Anorectal Branch of Chinese Medical Doctor Association, Anorectal motility disorders Committee , Colorectal Surgeons Branch of Chinese Medical Doctor Association, Colonic Branch of China international exchange and promotive association for medical and healthcare, Tianjin Union Medical Center is leading the organization of domestic experts in this field. Based on searching relevant literature and combining clinical experience at home and abroad, after multiple discussions, the "Chinese expert consensus on colonic and anorectal manometry" has been prepared. This consensus discusses the indications, contraindications, pre examination management and technical procedures, treatment of complications, and interpretation of examination reports for colonic and anorectal manometry , aiming to guide the standardized clinical practice of colonic and anorectal manometry.

Chinese expert consensus on the diagnosis and treatment of sacrococcygeal pilonidal disease (2023 edition) / 中华胃肠外科杂志

Sacrococcygeal pilonidal disease(SPD) is an acquired disease intimately related to the presence of hair in the gluteal groove. Although its pathogenesis is still controversial, numerous treatment options are available for SPD including gluteal groove and surrounding skin hair removal, sinusectomy, open healing by secondary intention, primary closure, and local excision with flap reconstruction. Lacking of standardized diagnosis and treatment processes of SPD in China, Chinese Medical Doctor Association Anorectal Branch and its Clinical Guidelines Committee jointly organized experts in this field to form expert consensus opinion on the basis of summarizing latest research progress in China and abroad, experts' clinical experience and principles of evidence-based medicine. The expert group formed opinion in 12 terms of SPD diagnosis, risk factors, non-surgical treatment, surgical treatment, minimally invasive treatment, and wound management, and developed the "Chinese expert consensus on the diagnosis and treatment of sacrococcygeal pilonidal disease (2023 edition)" after rounds of discussion and revision, to improve the diagnosis and treatment of SPD.

The consensus provides opinions on the detection technology and clinical application of CTC detection in the diagnosis and treatment of gastrointestinal neoplasms, including the prediction of tumor prognosis, the monitoring of tumor recurrence and metastasis, the evaluation of treatment response, and the additional diagnostic value, providing guidance for clinical application.

Consensus and operating guidelines of Chinese experts on transanal endoscopic surgery (2023 edition) / 中华胃肠外科杂志

Although transanal endoscopic surgery has been developed for more than 40 years, it remains relatively unknown to most domestic colleagues. In 2019, the Chinese Society of Transanal Total Mesorectal Excision (CSTa) and the Chinese Society of Colon and Rectal Surgeons (CSCRS) organized domestic experts to write and publish the "Chinese Expert Consensus on Transanal Endoscopic Surgery (2019 Edition)", which elaborated on the definition, surgical methods, indications, contraindications, basic principles, key issues and complications of transanal endoscopic surgery, and provided a certain theoretical foundation for the development of transanal endoscopic surgery in China. In the past four years, the scope of application of transanal endoscopic techniques has been expanded, and many prospective and retrospective clinical research have provided more evidence-based medical evidence. Therefore, the Chinese Society of Transanal Total Mesorectal Excision (CSTa) once again organized domestic experts to write the "Expert Consensus and Operation Guidelines for Transanal Endoscopic Surgery in China (2023 Edition)", updating the expert consensus opinions on the definition, indications, complications and learning curve of transanal endoscopic surgery and adding operation guidelines. The aim is to promote the standardized practices in transanal endoscopic surgery and facilitate a shorter learning curve for surgeons.
