Alergia a las proteínas de la leche de vaca: proceso diagnóstico. Consenso interdisciplinario de expertos / Cow's milk allergy: diagnostic process. Expert consensus

Las proteínas de la leche de vaca pueden causar alergia alimentaria. Los distintos mecanismos de acción involucrados y la variabilidad clínica según la etapa de la vida pediátrica en la que se manifieste ocasionan dificultades en su abordaje, con riesgo de sub- o sobrediagnóstico. En este proceso, intervienen profesionales de diversas áreas y es recomendable su interacción. Es por ello que el objetivo de este consenso ha sido reflejar el conocimiento actualizado desde la interdisciplina, generando recomendaciones para su correcto diagnóstico. Hemos trabajado con el método de Delphi para sumarle a la evidencia científica, la experiencia proveniente de neonatólogos, pediatras, especialistas en alergia, nutrición y gastroenterología. Pensamos que este enfoque interdisciplinario de trabajo va a resultar de utilidad práctica y promoverá una atención más integral de estos pacientes.

Cow's milk protein can cause food allergy. The different mechanisms of action involved, the clinical variability depending on the stage of pediatric life in which it manifests, leads to difficulties in its approach, with the risk of under- or over-diagnosis. Professionals from various areas intervene in this process and their interaction is recommended. That is why the objective of this consensus has been to reflect the updated knowledge in an interdisciplinary mode, generating recommendations for its correct diagnosis. We have worked with the Delphi method to add to the scientific evidence, the experience from neonatologists, pediatricians, experts in allergy, nutrition and gastroenterology. We think that this interdisciplinary approach will be of practical use and will promote more comprehensive care for these patients.

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.

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 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.

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.

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.

Clasificación de Rosemont para pancreatitis crónica / Rosemont classification for chronic pancreatitis

Chronic pancreatitis is a persistent fibroinflammatory disease of the pancreas, more common in smokers or alcoho- lics. Genetic predisposition with mutations in various genes has also been documented. It typically presents with recurrent abdominal pain and endocrine and exocrine dysfunction, potentially progressing to pancreatic cancer and severe complications in later stages. In Chile, an annual incidence of 0.8 cases per 100,000 inhabitants is estimated, with a prevalence of 6.1 cases per 100,000 inhabitants. Early diagnosis is a current challenge for which endosonography has emerged as a sensitive and specific diagnostic tool, especially with the implementation of the Rosemont classification. Various studies have validated the utility of this classification. However, the limited availability of endosonography in some countries, such as Chile, establishes challenges for generalizing its appli- cation. It is expected that in the future, the Rosemont classification will become a standard for the diagnosis of chronic pancreatitis.

La pancreatitis crónica es una enfermedad fibroinflamatoria persistente del páncreas, más común en fumadores o alcohólicos. De igual forma se ha documentado predisposición genética con mutaciones de distintos genes. Usualmente se manifiesta con dolor abdominal recurrente y disfunción endocrina y exocrina, pudiendo llegar a desarrollar cáncer de páncreas y graves complicaciones en fases tardías. En Chile, se estima una incidencia anual de 0,8 casos por 100.000 habitantes, con una prevalencia de 6,1 casos por cada 100.000 habitantes. El diagnóstico temprano es un desafío para el cual la endosonografía ha destacado como una herramienta diagnóstica sensible y específica, especialmente con la implementación de la clasificación de Rosemont. Distintos estudios han validado la utilidad de esta clasificación. Sin embargo, la limitada disponibilidad de endosonografía en algunos países, como Chile, plantea desafíos para generalizar su aplicación. Se espera que en un futuro la clasificación de Rosemont se convierta en un estándar para el diagnóstico de pancreatitis crónica.

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)

Primer Consenso intersocietario para el tratamiento de la obesidad en adultos en Argentina / First intersocietary Consensus for the treatment of obesity in adults in Argentina

Observando epistemológicamente la obesidad, fue Hipócrates de Cos (460 a.C.), con su método sobre la experiencia sensible, quién manifestó que "la muerte súbita es más frecuente en los obesos que en los delgados" y que "el obeso tiene laxitud muscular y complexión roja por humedad".Claudio Galeno de Pérgamo (130-201) hizo referencia a dos tipos de obesidad: la moderada, considerada como natural, y la inmoderada, como mórbida, producto de un estilo de vida inadecuado, teniendo el individuo un importante grado de culpabilidad y responsabilidad por su enfermedad

Consenso intersocietario para el tratamiento de la obesidad en adultos en Argentina / Intersocietary Consensus for the treatment of obesity in adults in Argentina

La obesidad es una enfermedad crónica que genera altos costos en salud, cuyo tratamiento, en ocasiones, no se aborda o se lo hace de forma inadecuada, y muchas veces no se basa en la evidencia disponible.

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.

Chinese consensus on open abdomen therapy (2023 edition) / 中华胃肠外科杂志

Open abdomen therapy is an effective treatment to deal with severe abdominal infections, abdominal hypertension and other critical abdominal diseases. However, this therapy is difficult to implement and has many uncertainties in the timing, manners, and follow-up treatment, which leads to the fact that open abdomen therapy is not very accessible and standardized in medical systems of China. This consensus aims to provide guiding principles for indications and implementation of open abdomen, classification methods of open abdomen wounds, technologies for abdominal closure, and management of enteroatmospheric fistula, so as to improve the accessibility and success rate of open abdomen in China.

Interpretation of Chinese expert consensus on the pelvic exenteration for primary rectal cancer beyond total mesorectal excision planes and locally recurrent rectal cancer (2023 edition) / 中华胃肠外科杂志

The China PelvEx Collaborative, under the direction of Colorectal Cancer Committee of the Chinese Medical Doctor Association, Gastrointestinal Surgery Committee of China International Exchange and Promotive Association for Medical and Health, has formulated and issued the Chinese expert consensus for primary rectal cancer beyond total mesorectal excision planes and locally recurrent rectal cancer (2023 edition) , with the academic support of the Chinese Journal of Gastrointestinal Surgery and Chinese Journal of Colorectal Disease (Electronic Edition). This Consensus refers to the expert consensus developed by the International PelvEx Collaboration, incorporates the latest international multi-center research results and combines the latest research results in China. The Consensus unifies some definitions, clarifies the surgical indications, and puts forward the definition and preventive measures of "empty pelvic syndrome" earlier. For the controversial classification of local recurrent rectal cancer, the Chinese classification was proposed for the first time in Consensus. At the same time, the definition of pelvic exenteration is controversial, and a more consistent cognition is proposed. It is believed that, with the in-depth research on complicated rectal cancer, C-PelvEx will gather more higher-level data from clinical research in several domestic centers, so as to further enrich the content of the updated Consensus.
