Rationality for the Use of Neuromodulation in Disorders of Gut-Brain Interaction (Functional Gastrointestinal Disorders)

Within the broad range of therapeutic options for managing functional gastrointestinal disorders, recently redefined as Disorders of Gut-Brain Interaction (DGBI) by the Rome Foundation in the Rome IV criteria, certain medications with antidepressant, anxiolytic, or antipsychotic effects are commonly employed. These drugs, now referred to as neuromodulators by the Rome Foundation, target the neurogastroenterological dysfunction associated with these disorders. Consequently, their clinical utility as psychiatric medications can now be leveraged to benefit patients with DGBI. This narrative review aims to provide an updated and specific overview of the indications for neuromodulators in the primary DGBI. The first section of this review focuses on the rationale and justification for their use.

En el amplio espectro de las opciones terapéuticas para el manejo de los trastornos funcionales digestivos, que se han redefinido por la Fundación Roma en los criterios Roma IV como trastornos de la interacción cerebro-intestino (TICI), algunos medicamentos con efectos antidepresivos, ansiolíticos o antipsicóticos se utilizan con mayor frecuencia. Estos medicamentos, que actúan en la disfunción neurogastroenterológica de estos trastornos, también han sido renombrados por la Fundación Roma como neuromoduladores, para que ahora puedan aprovecharse sus beneficios terapéuticos en este ámbito clínico, debido a su utilización como medicamentos psiquiátricos. Esta revisión narrativa tiene por objeto actualizar y precisar las indicaciones de los neuromoduladores en los principales TICI, y en esta primera sección se aborda la racionalidad y justificación para su utilización.

Recommendations for the diagnosis and management of persons with suspected vaccine-induced immune thrombotic thrombocytopenia (VITT) / Recomendaciones para diagnostico y manejo de personas con trombocitopenia trombotica inmune inducida por vacunas (VITT)

Abstract In recent months, rare cases of thrombosis at unusual sites associated with thrombocytopenia, occurring within a typical risk window (i.e., 4-28 days) after receiving SARS CoV2 vaccines, have been reported. Healthcare professionals should be prepared to detect these cases on time. The Expert Panel of the Knowledge Management and Transfer Network conducted a free search of the related literature. With the available information and the clinical expertise of the working group, we formulated, reviewed, and endorsed recommendations for the timely suspicion, diagnosis (case definitions, the use of initial laboratory and imaging tests, specific tests), and management of these thrombotic conditions. This document is considered a living document that will be updated as new evidence emerges, and recommendations may change over time.

Resumen En meses recientes se han reportado casos raros de trombocitopenia y trombosis en sitios inusuales, que ocurren dentro de una ventana de riesgo típica ( por ejemplo de 4 a 28 días) luego de recibir vacunas de SARS CoV 2. Los profesionales de la salud deben estar preparados para detectar estos casos a tiempo. Un panel de expertos y una red de transferencia de conocimiento realizó una búsqueda libre de literatura seleccionada. Con la información disponible y la experticia clínica del grupo de trabajo revisamos y dimos recomendaciones para la sospecha temprana, el diagnostico (definición de caso, el uso de pruebas de laboratorio especificas y de imágenes diagnósticas) para le manejo de estas condiciones tromboticas. Este documento es considerado un documento vivo que debe ser actualizado a medida que surja nueva evidencia y las recomendaciones vayan cambiando con el tiempo

Polipectomía endoscópica de colon: efectividad y seguridad de la técnica de inyectar y cortar / Efficacy and safety of the inject and cut technique for endoscopic colonic polypectomy

Colonic polypectomy is the most important tool for stopping adenoma-cancer, and the inject and cut technique has demonstrated efficacy and safety in studies conducted in other countries. Since in our country there are no reported data on performance of this technique, it is necessary to describe the experience of a gastroenterology unit of a university. Objectives: The objectives of this study were to describe operational characteristics of endoscopic colonic polypectomy using the inject and cut technique and to describe demographic characteristics of patients undergoing this procedure. Materials and Methods: We included all patients who underwent endoscopic colonic polypectomies in the gastroenterology unit of the Clínica Fundadores in Bogotá from January 2003 to September 2011. Data were processed using SPSS version 18 18.8 (SPSS-IBM) statistical package. Results: 420 patients underwent polypectomies which resected a total of 548 polyps. Mean patient age was 56.3 years (range 14 to 93), 201 patients were male, and 219 were female. Polyps were most commonly located in the left colon (238/64.4%). Average size was 1.6 cm. 83.8% were pedunculated, 13.3% were sessile, and 2.85% were flat. Intraoperative bleeding occurred in 36 cases (8.6%). There was no relationship between this complication and the size of polyps (<= 20vs> 20 mm), OR: 0.44 (CI 0.19-1.01), nor with the number of resected polyps (1Vs> 1) OR: 1.44, (95%:0.65-3 .2). All cases of bleeding were controlled endoscopically without further complications. There was no need for surgery. There were no local recurrences during follow-up. Conclusions: This study showed that the inject and cut technique is a practical, effective, economical and easy to perform technique for removal of colonic polyps. To date this is the largest series published in our country on the subject

Hepatitis B inactiva. Decisiones en la práctica clínica / Inactive hepatitis B. Decisions in the clinical practice

La mayoría de portadores crónicos del HBsAg son portadores inactivos de la hepatitis B. A pesar de que en términos generales tiene buen pronóstico a largo plazo, posee un riesgo incrementado de cirrosis hepática y hepatocarcinoma respecto a la población general. Además, es un grupo con alto riesgo de complicaciones, incluso letales, en caso de recibir medicamentos hepatotóxicos o inmunosupresores, lo cual requiere una serie de medidas diagnósticas y terapéuticas oportunas por parte del médico tratante. En este artículo presentamos una revisión de la hepatitis B inactiva, haciendo énfasis en el abordaje que debe realizarse en los escenarios clínicos que con mayor frecuencia ocurren en este grupo de pacientes.

Most chronic carriers of HBsAg are inactive carriers. Although in general have a good prognosis in the long term, have an increased risk of liver cirrhosis and hepatocellular carcinoma with respect to the general population. It is also a group at high risk of complications, even lethal, if given hepatotoxic or immunosuppressive drugs, which requires a series of diagnostic and therapeutic measures necessary for the treating physician. In this article we present a review of inactive hepatitis B, emphasizing the approach to be implemented in clinical scenarios that occur most frequently in this patient group.
