La pandemia por COVID-19 ha obligado a establecer medidas para evitar los contagios durante la realización de pruebas diagnósticas y terapéuticas en gastroenterología. Los estudios motores del tubo digestivo implican un riesgo elevado e intermedio de trasmisión de la infección por este virus. Dada su indicación electiva o no urgente en la mayoría de los casos, recomendamos diferir la realización de estas pruebas hasta que haya un control significativo de la tasa de infección en cada país, durante la pandemia. Cuando las autoridades sanitarias permitan el regreso a la normalidad y en ausencia de un tratamiento efectivo o una vacuna preventiva de la infección por COVID-19, recomendamos un protocolo estricto para clasificar a los pacientes de acuerdo a su estatus infecto-contagioso mediante el uso apropiado de pruebas para la detección del virus y su respuesta inmune, así como el uso de medidas de protección que deberá seguir el personal de la salud para evitar el contagio durante la realización de una prueba de motilidad gastrointestinal.
The perfusion system yielded results similar to that of solid state systems. Further studies to evaluate parameters with respect to pelvic dyssynergia and incontinence need to be conducted. Additionally, to determine if the vector volume can furnish new information in terms of functional and anatomical aspects.
BACKGROUND: The high-resolution manometry has been a significant advance in esophageal diagnostics. There are different types of catheter and systems devices to capture esophageal pressures that generate variable data related to Chicago Classification (CC) and consequently influence normal values results. There are not normative data for the 24-channel water-perfused high-resolution manometry system most used in Brazil with healthy volunteers in supine posture. OBJECTIVE: To determine manometric esophageal normative values for a 24-channel water-perfused high-resolution manometry catheter in supine posture using healthy volunteers according to CC 3.0 parameters. METHODS: A total of 92 volunteers with no gastrointestinal symptoms or medications affecting GI motility underwent esophageal high-resolution manometry by standard protocol. Age, gender and manometry parameters analyzed using Alacer software were collected. The median, range, and 5th and 95th percentiles (where applicable) were obtained for all high-resolution manometry metrics. Normal value percentiles were defined as 95th integrated relaxation pressure, 5th-100th distal contractile integral, and 5th distal latency. RESULTS: The mean age was 40.5±13.2 years. Our normative metrics were integrated relaxation pressure <16 mmHg and distal contractile integral (708-4111 mmHg.cm.s) distal latency was <6 s and peristaltic break size (>4 cm). For EGJ-CI the range 5th-95th was 21.7-86.9 mmHg.cm.s. CONCLUSION: This is the first report of normative data for the 24-channel water-perfused system in supine posture. It revealed higher integrated relaxation pressure and distal latency duration which suggest the need to change CC 3.0 cutoffs for this system. It is observed that there is a tendency that DCI >7000 mmHg.cm.s may represent the lower limit of hypercontractility, and when <700 mmHg.cm.s (<5% percentile) interpreted as ineffective esophageal motility or failcontraction. Also compared to Chicago 3.0, higher integrated relaxation pressure and duration of distal latency were found. We emphasize that these data must be confirmed by future studies.

Due to its concern about the future of Brazilian scientific journals after new criteria were adopted by the QUALIS system of CAPES (Brazilian Federal Agency for the Improvement of Higher Education), the Brazilian Medical Association (Associação Médica Brasileira -AMB) has held several meetings at its headquarters in São Paulo to discuss this matter. Editors of the main Brazilian medical journals, directors of the Brazilian Association of Scientific Editors (Associação Brasileira de Editores Científicos -ABEC), and coordinators of the areas Medicine II and Medicine III of CAPES exchanged information and came out with proposals aimed at improving the evaluation process of Brazilian scientific journals by the new QUALIS system of CAPES. The classification of the scientific production according to the QUALIS system will
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
