RESUMO

Background: Replacement of cytology screening with HPV testing is recommended and essential for cervical cancer elimination. HPV testing for primary screening was implemented in 12 laboratories within 9 Latin American countries, as part of the ESTAMPA cervical cancer screening study. Our observations provide information on critical operational aspects for HPV testing implementation in diverse resource settings. Methods: We describe the implementation process of HPV testing in ESTAMPA, focusing on laboratory aspects. We assess the readiness of 12 laboratories to start HPV testing and their continuity capacity to maintain good quality HPV testing until end of recruitment or up to December 2021. Readiness was based on a checklist. Information from the study database; regular meetings and monitoring visits; and a questionnaire on laboratory operational aspects sent in May 2020 were used to assess continuity capacity. Compliance with seven basic requirements (readiness) and eight continuity requirements (continuity capacity) was scored (1 = compliant, 0 = not compliant) and totaled to classify readiness and continuity capacity as very limited, limited, moderate or high. Experiences, challenges, and enablers of the implementation process are also described. Results: Seven of 12 laboratories had high readiness, three moderate readiness, and of two laboratories new to HPV testing, one had limited readiness and the other very limited readiness. Two of seven laboratories with high readiness also showed high continuity capacity, one moderate continuity capacity, and the other four showed limited continuity capacity since they could not maintain good quality HPV testing over time. Among three laboratories with moderate readiness, one kept moderate continuity capacity and two reached high continuity capacity. The two laboratories new to HPV testing achieved high continuity capacity. Based on gained expertise, five laboratories have become part of national screening programs. Conclusion: High readiness of laboratories is an essential part of effective implementation of HPV testing. However, high readiness is insufficient to guarantee HPV testing high continuity capacity, for which a "culture of quality" should be established with regular training, robust monitoring and quality assurance systems tailored to local context. All efforts to strengthen HPV laboratories are valuable and crucial to guarantee effective implementation of HPV-based cervical screening.

RESUMO

Glyphosate [N-(phosphonomethyl)glycine] is the active ingredient in widely used broad-spectrum herbicides. Even though the toxicity mechanism of this herbicide in vertebrates is poorly understood, evidence suggests that glyphosate is an endocrine disruptor capable of producing morphological anomalies as well as cardiotoxic and neurotoxic effects. We used the zebrafish model to assess the effects of early life glyphosate exposure on the development of cartilage and bone tissues and organismal responses. We found functional alterations, including a reduction in the cardiac rate, significant changes in the spontaneous tail movement pattern, and defects in craniofacial development. These effects were concomitant with alterations in the level of the estrogen receptor alpha osteopontin and bone sialoprotein. We also found that embryos exposed to glyphosate presented spine deformities as adults. These developmental alterations are likely induced by changes in protein levels related to bone and cartilage formation.

RESUMO

Objetivo: conocer desde la perspectiva social, los conocimientos y creencias de la población a partir del significado que las personas le atribuyen a las vacunas preventivas y al proceso de vacunación. Métodos: Se realizó un estudio exploratorio con familiares de niños de 0 a 24 meses pertenecientes al Policlínico 5 de Septiembre, municipio Playa, La Habana, que abarcó de enero a junio de 2015. Se utilizó un diseño mixto convergente o por triangulación de datos. Para la recolección de datos se utilizó la entrevista-cuestionario, entrevista a expertos y entrevista a informantes claves. Se elaboró una base de datos en Excel, la que se exportó al programa SPSS versión 19.0. En un primer momento, se realizó un análisis descriptivo, en el que se calcularon frecuencias absolutas y relativas para las variables de estudio. Para establecer las relaciones entre el nivel de conocimiento y algunas variables sociodemográficas, para el análisis de los datos cualitativos, se realizaron lecturas reiteradas de las transcripciones de las entrevistas a expertos e informantes claves y de las respuestas a las preguntas abiertas del cuestionario para la familiarización con el contenido de estos. Resultados: Se puso de manifiesto la vía institucional en la cultura de la salud que poseen los familiares con relación a las vacunas y el proceso de vacunación. Los familiares presentaban en su mayoría conocimientos insuficientes acerca de las vacunas y las enfermedades que protegen estas. No presentaban conocimientos sobre los eventos adversos graves o severos. El proceso de vacunación mostró gran significado para los familiares, asociados a experiencias positivas con este. Conclusiones: Se inicia un acercamiento a la cultura de la salud, poseída por un grupo de familiares, relativos a las vacunas preventivas y el proceso de vacunación en Cuba. Las madres refuerzan la responsabilidad de vacunar al niño/a como parte del cuidado de la salud de este. La cultura de la salud en los familiares de niños/as no incluye información distorsionada sobre las vacunas preventivas y su efectividad. Se nutre exclusivamente de la cultura científica, aunque no la reproduce en su totalidad. El proceso de vacunación es altamente valorado por los familiares, dada la importancia que le atribuyen, la confianza que tienen en el Programa Nacional de Inmunización, la satisfacción que muestran con la organización del servicio y la atención del personal de salud(AU)


Objective: to know, from the social perspective, the population´s knowledge and beliefs based on the meaning that people attribute to preventive vaccines and the vaccination process. Methods: An exploratory study was carried out with relatives of children from 0 to 24 months from "5 de Septiembre" community clinic in Playa municipality, Havana, from January to June 2015. A mixed convergent or triangulation design was used. Data collection was completed by questionnaire interview, expert interview and interview to key informants. A database was created in Excel, which was exported to the SPSS program version 19.0. Initially, a descriptive analysis was performed, in which absolute and relative frequencies were calculated for the study variables. Repeated readings were made of the transcripts of the interviews with experts and key informants and for the answers to the open questions of the questionnaire, to establish the analysis of the qualitative data, and for familiarization with their content. Results: It was shown the institutional pathway in health culture that family members have in relation to vaccines and the vaccination process. Most family members had poor knowledge about vaccines and the diseases they prevent. They did not show knowledge about serious or severe adverse events. The vaccination process showed great significance for family members, associated with positive experiences with it. Conclusions: This study initiates an approach to the health culture a group of family members had related to preventive vaccines and the vaccination process in Cuba. Mothers reinforce the responsibility of vaccinating the child as part of their child's health care. The health culture in family members of children does not include distorted information about preventive vaccines and their effectiveness. Their knowledge is fed exclusively by scientific culture, although it is entirety not reproduce. The vaccination process is highly valued by family members, given the importance they attach to it, the confidence they have in the National Immunization Program, the satisfaction they show with the organization of the service and the care of health personnel(AU)

RESUMO

OBJECTIVE: To evaluate the effects of timing of depot medroxyprogesterone acetate injection on medical abortion outcome and risk of repeat pregnancy within the subsequent 6 months. METHODS: In a multinational randomized trial, we assigned women undergoing medical abortion who wanted depot medroxyprogesterone acetate to administration either with mifepristone (Quickstart group) or after the abortion (Afterstart group). We ascertained abortion outcome, pregnancies, and contraception use over 7 months. RESULTS: From August 2013 to March 2015, we enrolled 461 participants with pregnancy durations of 75 days or less. Of participants included in the abortion outcome analyses, 14 of 220 (6.4%) and 12 of 226 (5.3%) in the Quickstart and Afterstart groups, respectively, had surgery to complete the abortion; the upper 90% confidence limit on this difference was 4.9%, within our prestipulated 5% noninferiority margin. Ongoing pregnancy after initial abortion treatment was significantly more common in the Quickstart group (8/220 [3.6%]) than in the Afterstart group (2/226 [0.9%]); the difference was 2.7% (90% confidence interval 0.4-5.6%). By 6 months, 5 of 213 (2.3%) and 7 of 217 (3.2%) in the Quickstart and Afterstart groups, respectively, became pregnant (exact log-rank test, P=.64). Use of highly effective contraceptives was significantly more common in the Quickstart group at 31 days (P<.001), but no difference was apparent at 6 months. The Quickstart group was significantly more satisfied with group assignment. CONCLUSION: Depot medroxyprogesterone acetate administration with mifepristone did not appreciably increase the risk of surgery after medical abortion but did increase the risk of ongoing pregnancy. It enhanced patient satisfaction, but we found no evidence that it decreased 6-month risk of repeat pregnancy.

RESUMO

OBJECTIVE: To evaluate the effect of insertion of etonogestrel implants with mifepristone compared with after the abortion on the risks of medical abortion failure and repeat pregnancy over the subsequent 6 months. METHODS: In a randomized trial, we assigned patients undergoing medical abortion to receive etonogestrel implants either with the mifepristone (Quickstart group) or after the abortion (Afterstart group). We followed them for 7 months to ascertain abortion outcome, pregnancies, and contraception use. RESULTS: Between September 2013 and August 2014, we enrolled 236 participants in the Quickstart group and 240 in the Afterstart group. To examine abortion failure, we conducted a noninferiority analysis from which we excluded nine participants who had missing outcome data and four with specified protocol violations. Of the rest, 9 of 229 (3.9%) and 9 of 234 (3.8%) in the Quickstart and Afterstart groups, respectively, had surgery to complete the abortion; the difference of 0.08% (90% confidence interval -3.1% to 3.3%) excluded our prestipulated noninferiority margin of 5 percentage points. Among participants with pregnancy follow-up through 6 months, 1 of 213 (0.5%) and 3 of 208 (1.4%) in the Quickstart and Afterstart groups, respectively, became pregnant within that time; 6-month pregnancy rates did not differ significantly by group (exact log-rank test, P=.28). At enrollment, significantly more participants in the Quickstart group than in the Afterstart group were satisfied with their group assignments (187/236 [79%] compared with 129/240 [54%], respectively; P<.001). CONCLUSION: Insertion of etonogestrel implants with mifepristone did not appreciably increase medical abortion failure risk and it enhanced patient satisfaction, but we found no evidence that it decreased repeat pregnancy rates.
