Peer Review Process

Manuscripts submitted to Memorias del Instituto de Investigaciones en Ciencias de la Salud undergo a double-blind peer review process, in which the identities of both authors and reviewers remain anonymous throughout the evaluation. Each manuscript is assessed by a minimum of two external reviewers with expertise in the relevant subject area, who are given a period of 30 days to submit their evaluation. Reviewers assess the originality, methodological rigor, scientific relevance, and clarity of presentation of each work. Based on the reviewers' reports, the Editorial Committee decides whether to accept, request revisions, or reject the manuscript, and communicates the decision to the authors as promptly as possible. This process ensures impartiality, transparency, and the scientific quality of published articles.

Abstract

Trabajos han demostrado la utilidad de la captura híbrida II (CH IIâ) en la detección del virus de papiloma humano de alto riesgo oncogénico (HR-HPV) como método de tamizaje primario para detección de cáncer de cuello uterino, así como las bondades de la PCR que permite acceder a métodos de tipificación viral. Por ello el objetivo fue detectar el genoma del HPV por PCR a partir de muestras de CH IIâ cien veces diluidas. Estudio transversal en 141 muestras cervicales de mujeres con citología normal y anormal que concurrieron al IICS, UNA. Las muestras fueron procesadas por CH IIâ y almacenadas con reactivo desnaturalizante a -80ºC. Luego, las muestras fueron diluidas 100 veces con agua destilada y posteriormente procesadas por PCR. Se detectó HPV en 51% y 43% de las muestras analizadas por CH IIâ y PCR, respectivamente. Diecisiete de 23 muestras positivas por CH IIâ con carga viral relativa baja fueron negativas por PCR. Esto podría deberse a la degradación del material. Además, 6 muestras negativas por CH IIâ fueron positivas por PCR sugiriendo presencia de infección con tipos virales no incluidos en CH IIâ. Estos resultados sugieren que es posible realizar la detección de HPV por PCR en muestras procesadas por CH IIâ previa dilución. Esta propuesta rápida, sencilla y económica, minimiza el riesgo de perder el material genético en la extracción y permite acceder a métodos de tipificación viral que podrían contribuir con datos sobre tipos de HPV circulantes para realizar una vigilancia en la era post-vacunal.
