RESUMO

BACKGROUND: Colposcopy, currently included in WHO recommendations as an option to triage human papillomavirus (HPV)-positive women, remains as the reference standard to guide both biopsy for confirmation of cervical precancer and cancer and treatment approaches. We aim to evaluate the performance of colposcopy to detect cervical precancer and cancer for triage in HPV-positive women. METHODS: This cross-sectional, multicentric screening study was conducted at 12 centres (including primary and secondary care centres, hospitals, laboratories, and universities) in Latin America (Argentina, Bolivia, Colombia, Costa Rica, Honduras, Mexico, Paraguay, Peru, and Uruguay). Eligible women were aged 30-64 years, sexually active, did not have a history of cervical cancer or treatment for cervical precancer or a hysterectomy, and were not planning to move outside of the study area. Women were screened with HPV DNA testing and cytology. HPV-positive women were referred to colposcopy using a standardised protocol, including biopsy collection of observed lesions, endocervical sampling for transformation zone (TZ) type 3, and treatment as needed. Women with initial normal colposcopy or no high-grade cervical lesions on histology (less than cervical intraepithelial neoplasia [CIN] grade 2) were recalled after 18 months for another HPV test to complete disease ascertainment; HPV-positive women were referred for a second colposcopy with biopsy and treatment as needed. Diagnostic accuracy of colposcopy was assessed by considering a positive test result when the colposcopic impression at the initial colposcopy was positive minor, positive major, or suspected cancer, and was considered negative otherwise. The main study outcome was histologically confirmed CIN3+ (defined as grade 3 or worse) detected at the initial visit or 18-month visit. FINDINGS: Between Dec 12, 2012, and Dec 3, 2021, 42 502 women were recruited, and 5985 (14·1%) tested positive for HPV. 4499 participants with complete disease ascertainment and follow-up were included in the analysis, with a median age of 40·6 years (IQR 34·7-49·9). CIN3+ was detected in 669 (14·9%) of 4499 women at the initial visit or 18-month visit (3530 [78·5%] negative or CIN1, 300 [6·7%] CIN2, 616 [13·7%] CIN3, and 53 [1·2%] cancers). Sensitivity was 91·2% (95% CI 88·9-93·2) for CIN3+, whereas specificity was 50·1% (48·5-51·8) for less than CIN2 and 47·1% (45·5-48·7) for less than CIN3. Sensitivity for CIN3+ significantly decreased in older women (93·5% [95% CI 91·3-95·3] in those aged 30-49 years vs 77·6% [68·6-85·0] in those aged 50-65 years; p<0·0001), whereas specificity for less than CIN2 significantly increased (45·7% [43·8-47·6] vs 61·8% [58·7-64·8]; p<0·0001). Sensitivity for CIN3+ was also significantly lower in women with negative cytology than in those with abnormal cytology (p<0·0001). INTERPRETATION: Colposcopy is accurate for CIN3+ detection in HPV-positive women. These results reflect ESTAMPA efforts in an 18-month follow-up strategy to maximise disease detection with an internationally validated clinical management protocol and regular training, including quality improvement practices. We showed that colposcopy can be optimised with proper standardisation to be used as triage in HPV-positive women.

RESUMO

INTRODUCCIÓN: El COVID-19 es eminentemente una infección de transmisión e inicio respiratorio, se discute la existencia de otras fuentes de contagio. El receptor viral ACE2 también ha sido detectado en el útero y en la vagina; de allí se ha planteado el compromiso del virus SARS-CoV-2 sobre el sistema genitourinario y sus posibles repercusiones en el embarazo. OBJETIVO: Determinar la presencia de SARS-CoV-2 en muestras endocervicales de mujeres con COVID-19 en departamentos del Paraguay. PACIENTES Y MÉTODOS: Diseño observacional prospectivo, de corte transverso. Se reclutaron 200 mujeres desde agosto 2020 hasta febrero 2021, con no más de 48/72 h de un resultado previo positivo de hisopado nasofaríngeo para SARS-CoV-2 por retrotranscriptasa reversa-reacción en cadena de la polimerasa (en inglés rt-RT-PCR) y que aceptaron ingresar al estudio. Se llenó un cuestionario clínico epidemiológico. Las tomas de muestras se realizaron en servicios de salud del Ministerio de Salud Pública y Bienestar Social (MSP y BS), domicilios y albergues de los distintos departamentos de Paraguay. Cada paciente fue sometida a un hisopado con hisopos de dacron o citobrush endocervical para la detección de SARS-CoV-2 por rt RT-PCR. Resultados: Las mujeres estudiadas tenían una edad media de 46,5 años (IC 95% 31,5-62,5). Refirieron contagio comunitario con SARS-CoV-2 en 75,5%, 13,5% en el hogar, 8,5% en el lugar de trabajo y 1,5% en el extranjero. Las manifestaciones clínicas fueron: 30%, síndrome gripal, fiebre 22,5%, tos 20%, anosmia 15,5%, trastornos digestivos 15,5%, y otros se presentaron con menor frecuencia. Las muestras de hisopados o citobrush endocervical sometidas a rt-RT-PCR para la deteccción de SARS Cov-2, resultaron negativas en las 200 mujeres de estudio. Discusión: Cabe destacar que las muestras vaginales fueron tomadas dentro de las 24-72 h de haber obtenido un resultado positivo para SARS-CoV-2 en el hisopado nasofaríngeo y que 62,5% de las mujeres se encontraban internadas en módulos respiratorios. Se discute la razón de la negatividad de los exámenes y su trascendencia. CONCLUSIÓN: No se detectó infección con SARS-CoV-2 en la región endocervical de 200 mujeres con manifestaciones clínicas de COVID 19 y evaluadas dentro de las 48/72 h de un resultado positivo nasofaríngeo para SARS Cov-2. Los resultados en la población de estudio concuerdan con otros estudios reportados en la literatura científica.


BACKGROUND: COVID-19 is an eminently respiratory transmissible infection of respiratory initiation, the existence of other sources of contagion is discussed. The ACE2 viral receptor has also been detected in the uterus and vagina; Hence, the involvement of the SARS-CoV-2 virus on the genitourinary system and its possible repercussions on pregnancy has been raised. AIM: To determine the presence of SARS-CoV-2 in endocervical samples of women with COVID-19 in the departments of Paraguay. METHODS: Designed as a prospective observational of transverse cohort. Two hundred women were recruited from August 2020 to February 2021, with no more than 48/72 hours of a previous positive nasopharyngeal swab result for SARS-CoV-2 by reverse transcriptase-polymerase chain reaction (rt-RT-PCR) and who agreed to participate in the study. A clinical epidemiological questionnaire was completed. The samples were taken in health services of the MSPYBS (Public Ministry of Health and Social Welfare), homes and shelters in the different departments of Paraguay. Each patient underwent a swab (dacron swabs) or endocervical cytobrush for the detection of SARS-CoV-2 by rt-RT-PCR. RESULTS: Women recruited had a mean age of 46.5 years (95% CI 31,562.5). They reported contagion with SARS-CoV-2: 75.5% in the community, 13.5% at home, 8.5% in the place of work and 1.5% abroad. The clinical manifestations were: 30% flu syndrome, 22.5% fever, 20% cough, 15.5% anosmia, 15.5% digestive disorders, among other symptoms. The swabs or endocervical cytobrush samples subjected to rt-RT-PCR for the detection of SARS-CoV-2 were negative in the 200 study women. Discussion: It should be noted that the vaginal samples were taken within 24-72 hours after obtaining a positive result for SARS-CoV-2 in the nasopharyngeal swab and that 62.5% of the women were hospitalized in respiratory modules. The reason for the negativity of the exams and their significance are discussed. CONCLUSION: No SARS Cov-2 infection was detected in the endocervical region of 200 women with clinical manifestations of COVID 19 and evaluated within 48/72 hours of a positive nasopharyngeal result for SARS Cov-2. The results in the study population agree with the findings of other studies reported in the literature.

RESUMO

Esta investigación fue realizada, como parte integrante del Proyecto de Innovación Curricular, con la necesidad de la construcción de un perfil de egresado, en el ciclo o asignaturas clínicas, para posteriormente, realizar el perfil del Egresado de la Facultad de Ciencias Médicas de la Universidad Nacional de Asunción (FCM-UNA). La misma, la fuimos construyendo a partir de artículos, documentos y actores relevantes tanto dentro y como fuera de la Institución, que permitió así contribuir en la construcción de una propuesta que optimice la formación universitaria de los estudiantes de la carrera de medicina. Como docentes de la universidad hemos constatado una serie de problemas que se relacionan tanto con el aislamiento de las disciplinas que se manejan en forma totalmente independientes dificultando un aprendizaje integrado de los estudiantes, como su poca formación en gestión, en investigación y la necesidad un estudio exhaustivo y de mejor relacionamiento interhumano con los pacientes y con los propios colegas. Seria apropiada para intencionar los procesos de enseñanza y aprendizaje y el perfil de un médico acorde a las necesidades político- social, cultural y de desarrollo económico. Nuestro objetivo fue analizar e interpretar documentos y percepción de los actores relevantes en cuanto a la formación de médico, que permita aportar datos para levantar una propuesta de perfil del ciclo clínico, integrado y pertinente a través de un diseño cualitativo con un énfasis comprensivo. Para el levantamiento de información se recurrió a la revisión de artículos, donde buscamos el perfil de otras Universidades de medicinas referentes, tantos de MERCOSUR, como Internacionales. Se realizaron focus group en docentes, pacientes y egresado de la FCM-UNA, también se utilizó entrevistas a empleadores del sector privado, público y seguro social. Posteriormente, se realizó el proceso de análisis de contenidos con interés interpretativo. En cuanto al resultado obtenido podemos decir que el egresado clínico debe reunir cierta competencia clínicas, además de buenos relacionamientos con los pacientes, parientes y sus propios colegas y el personal de apoyo. Cabe además señalar algunos actores coinciden en interacción comunicativas y además en incorporar tecnología de avanzadas, actualización permanente en los saberes disciplinares y en la investigación, una formación contextualizada social y que atienda las necesidades de salud de la población. Una demanda expresada convergentemente es la consideración de la gestión como parte del desempeño del médico, asimismo, en la dimensión de la responsabilidad social, pacientes, egresados y empleadores; relevan la necesidad de formar médicos con sentido humanista, comprometidos con el proyecto de justicia social y que sean éticos, advierten del peligro de la mercantilización del acto médico como regulador de la relación médico-paciente, entre otros. Un importante hallazgo de la investigación, fue la aparición de dos dimensiones demandadas en la formación del médico como es la enseñanza/docencia


This research was conducted as part of the Curricular Project Innovation, with the need of building a graduate profile in the clinical cycle or subjects, to then make the profile of the graduate of the Faculty of Medical Science at the National University of Asunción (FCM-UNA). We were building it through articles, documents and relevant actors within and outside the institution, enabling the contribution in building a proposal that optimizes the university education of medical students. As university teachers we have found a series of problems related to both the isolation of the disciplines that are used in totally independent way hindering an integrated learning for students, as the little training in management, research and the need for a thorough study and better inter-human relationship with patients and with colleagues. This would be appropriate to address the teaching and learning and the profile of a doctor according to the social, cultural, political and economic development needs. Our objective was to analyze and interpret documents and perception of stakeholders regarding the medical training, that allow to provide data that would give a proposal of the clinical cycle, integrated and relevant through a qualitative design with a comprehensive focus. A review of articles was used to gather information, which seek the profile of other medical universities, both MERCOSUR and International. focus groups were conducted in teachers, patients and graduated from the FCM-UNA. It was also used interviews with employers from the private, public and social security sectors. Subsequently, the process of content analysis was performed with interpretive interest. As for the results obtained we can say that the clinical graduate must meet certain clinical competence, including good relationship with patients, relatives and their own colleagues and support staff. It should also be noted some actors agree in communicative interaction and also to incorporate advanced technology, continuous updating on the disciplinary knowledge and research, social contextualized training and to address the health needs of the population. A convergent expressed demand is the consideration of management as part of the physician performance, also, in the dimension of social responsibility, patients, alumni and employers; they reveal the need to train physicians with humanistic sense, committed to the project of social justice and ethics, warn against the commodification of the medical act as a regulator of the doctor-patient relationship, among others. An important finding of the research was the appearance of two demanded dimensions in the medical training such as teaching.
