Exploring the potential of omics technologies in medicinal plant research: a review in Colombia / Explorando el potencial de las tecnologías ómicas en la investigación de plantas medicinales: una revisión en Colombia

This review presents advances in the implementation of high - throughput se quencing and its application to the knowledge of medicinal plants. We conducted a bibliographic search of papers published in PubMed, Science Direct, Google Scholar, Scopus, and Web of Science databases and analyzed the obtained data using VOSviewer (versi on 1.6.19). Given that medicinal plants are a source of specialized metabolites with immense therapeutic values and important pharmacological properties, plant researchers around the world have turned their attention toward them and have begun to examine t hem widely. Recent advances in sequencing technologies have reduced cost and time demands and accelerated medicinal plant research. Such research leverages full genome sequencing, as well as RNA (ribonucleic acid) sequencing and the analysis of the transcr iptome, to identify molecular markers of species and functional genes that control key biological traits, as well as to understand the biosynthetic pathways of bioactive metabolites and regulatory mechanisms of environmental responses. As such, the omics ( e.g., transcriptomics, metabolomics, proteomics, and genomics, among others) have been widely applied within the study of medicinal plants, although their usage in Colombia is still few and, in some areas, scarce.

Protective effect of trans-nerolidol on vascular endothelial cell injury induced by lipopolysaccharides / Efectos protectores del trans-nerolidol en lesiones inducidas por lipopolisacáridos en células endoteliales vasculares

This article aimed to discuss the protection of trans - nerolidol on vascular endothelial cells (ECs) injured by lipopolysac charides. ECs were divided into four groups: normal, model, low and high dose trans - nerolidol treatment groups. The cell survival rate and the contents of NO in the cell culture supernatant were determined. The protein expression and transcript level of pe roxisome proliferator - activated receptor - γ (PPARγ), endothelial nitric oxide synthase (eNOS), and inducible nitric oxide synthase (iNOS) were determined by western blotting and RT - PCR respectively. Compared with the normal group, cell livability, protein e xpression and mRNA transcript level of PPARγ and eNOS decreased, NO contents, protein expression and mRNA transcript tlevel of iNOS increased in model group significantly. Compared with model group, all the changes recovered in different degree in treatmen t groups. Hence, it was concluded that trans - nerolidol can alleviate the ECs injuryby the regulation of iNOS/eNOS through activating PPARγ in a dose - dependent manner

Las CE se di vidieron en cuatro grupos: normal, modelo, grupos de tratamiento con trans - nerolidol de baja y alta dosis. Se determinó la tasa de supervivencia de las células y los contenidos de óxido nítrico (NO) en el sobrenadante del cultivo celular. La expresión de p roteínas y el nivel de transcripción del receptor activado por proliferadores de peroxisomas - γ (PPARγ), el óxido nítrico sint et asa endotelial (eNOS) y el óxido nítrico sint et asa inducible (iNOS) se determinaron mediante western blot y RT - PCR, respectivamen te. En comparación con el grupo normal, la viabilidad celular, la expresión de proteínas y el nivel de transcripción de PPARγ y eNOS disminuyeron, los contenidos de NO, la expresión de proteínas y el nivel de transcripción de iNOS aumentaron significativam ente en el grupo modelo. En comparación con el grupo modelo, todos los cambios se recuperaron en diferentes grados en los grupos de tratamiento. Por lo tanto, se concluyó que el trans - nerolidol puede aliviar el daño en las CE regulando iNOS/eNOS a través d e la activación de PPARγ de manera dependiente de la dosis.

Extraction of geraniol from palmarosa oil using hydrotropic solvents / Extracción de geraniol del aceite de palmarosa utilizando solventes hidrotrópicos

The extraction of geraniol from palmarosa oil using hydrotropic solvents was investigated. Palmarosa oil possesses an appealing rose aroma and properties like anti - inflammatory, antifungal, and antioxidant due to the presence of geraniol. The extraction of geraniol from palmarosa oil by using distillation methods like steam dis tillation and fractional distillation was a laborious process. So hydrotropes were tried for extraction. The geraniol yield and purity depend on parameters like concentration of hydrotrope, solvent volume ratio, and time period. Using the Box Benkhem Desig n (BBD), the extraction process was optimized. One of the major advantages of using hydrotropic solvents is that they were classified as green solvents, and recovery of solvents is also possible. To reduce the extraction time probe sonication is carried ou t. Different hydrotropic solvents with probe sonication are done on palmarosa oil by altering various process parameters to study the separation, yield, and purity.

Se investigó la extracción de geraniol del aceite de palmarosa utilizando solventes hidrotrópicos. El aceite de palmarosa posee un atractivo aroma a rosa y propiedades antiinflamatorias, antifúngicas y antioxidantes debido a la pr esencia de geraniol. La extracción de geraniol del aceite de palmarosa mediante métodos de destilación como la destilación por vapor y la destilación fraccionada ha sido un proceso laborioso. Por lo tanto, se probaron los hidrotropos para la extracción. El rendimiento y la pureza del geraniol dependen de parámetros como la concentración del hidrotropo, la relación de volumen del solvente y el período de tiempo. Se optimizó el proceso de extracción usando el diseño Box Benkhem (BBD). Una de las principales v entajas de usar solventes hidrotrópicos es que se clasifican como solventes verdes y también es posible recuperar los solventes. Para reducir el tiempo de extracción, se lleva a cabo una sonda de ultrasonido. Se realizan diferentes solventes hidrotropos co n sonda de ultrasonido en el aceite de palmarosa alterando varios parámetros del proceso para estudiar la separación, el rendimiento y la pureza.

Resistencia antibiótica y aspectos clínicos de Neisseria gonorrhoeae anorrectal en un hospital de CABA, Argentina / Antimicrobial resistance and clinical aspects in anorectal Neisseria gonorrhoeae in a hospital in CABA, Argentina

La infección por Neisseria gonorrhoeae (NG) es considerada de alta prioridad en salud pública, por su capacidad para desarrollar resistencia a la mayoría de los antibióticos empleados para tratarla. La presentación anorrectal suele ser asintomática y frecuente en hombres que tienen sexo con hombres (HSH). En Argentina, se recomienda terapia antibiótica dual (ceftriaxona+azitromicina/doxiciclina) como primera línea empírica. Este estudio observacional y retrospectivo se realizó para evaluar el porcentaje de positividad de NG anorrectal, el perfil de sensibilidad a penicilina, tetraciclina, ciprofloxacina, ceftriaxona, cefixima y azitromicina, así como los aspectos clínicos-epidemiológicos de los pacientes atendidos entre 20/10/2015 y 20/03/2020 en consultorios coloproctológicos de un hospital público. Se detectaron 55/436 hisopados rectales positivos para NG (13%). El 95% era HSH y 71%, VIH+. En 18/55 NG fue la única infección. Las co-infecciones más frecuentes: HPV (38%) y C. trachomatis (35%). La sensibilidad a cefalosporinas de espectro extendido (CEE) y a azitromicina fueron 100% y 98%, respectivamente. Se observó la emergencia local de los primeros cinco aislamientos de NG anorrectal con sensibilidad reducida (SR) a CEE, el primer aislamiento con categoría no-sensible a azitromicina y otro con SR a azitromicina concomitantemente con SR a CEE. Aunque el uso de terapia empírica dual sigue siendo adecuado para nuestra institución, se observó la emergencia de aislamientos con SR y NS a las drogas de primera línea, evidenciando la importancia de la vigilancia epidemiológica a nivel local para definir los tratamientos empíricos.

Neisseria gonorrhoeae (NG) infection is considered a high public health priority because of its ability to develop resistance to most of the antibiotics used to treat it.The anorectal presentation is generally asymptomatic and frequent in men who have sex with men (MSM). In Argentina, dual therapy (ceftriaxone+azithromycin/doxycycline) is recommended as first line empiric therapy.This observational and retrospective study was conducted to evaluate the percentage of anorectal NG positivity, the susceptibility profile to penicillin, tetracycline, ciprofloxacin, ceftriaxone, cefixime and azithromycin, as well as the clinical-epidemiological aspects of patients attended between 20/10/2015 and 20/03/2020 in coloproctology of a public hospital.We detected 55/436 positive rectal swabs for NG (13%). 95% were MSM and 71% were PLHIV. In 18/55 NG was the only infection. The most frequent co-infections: HPV (38%) and C. trachomatis (35%).Susceptibility to extended-spectrum cephalosporins (ESCs) and azithromycin was 100% and 98%, respectively. Local emergence of the first five anorectal NG isolates with decreased susceptibility (DS) to ESCs, the first isolate with nonsusceptible category to azithromycin and another with DS to azithromycin concomitantly with DS to ESCs were observed.Although the use of dual empirical therapy continues to be adequate for our institution, the emergence of isolates with DS and NS to first-line drugs was observed, evidencing the importance of epidemiological surveillance at the local level to define empirical treatments

Los servicios de odontología en los tiempos del COVID- 19 en Colombia: análisis de país

Se desconoce el impacto que produjo la pandemia por el COVID-19 en la prestación y en la consulta de los servicios odontológicos y analizados según el sistema integrado de protección social o SISPRO en Colombia. El objetivo fue Determinar los cambios en la cobertura y los patrones de atención odontológica, entre los años pre pandemia (2017-2019) y los años de pandemia (2020-2021). Se analizaron los registros de las atenciones odontológicas reportadas en el sistema SISPRO del Ministerio de Salud de Colombia en periodos prepandemia y postpandemia por el COVID-19. En el año 2019 la tasa de cobertura por cada 100 habitantes en el estudio era de 31,14; sin embargo, la cobertura de atención odontológica se redujo al 17% en el 2020 y al 9% en el 2021 y las atenciones de urgencias disminuyeron drásticamente en los años 2020 y en el 2021. Se requiere que los tomadores de decisión promuevan los servicios de odontología para recuperar los niveles de cobertura previos a la pandemia. Se identificó una disminución en la cobertura odontológica asociada a la pandemia de la COVID-19 en los años 2020 y 2021 y desconocen cuales son los posibles efectos en la morbilidad bucal de los Colombianos.

Introduction. The COVID-19 pandemic affected Colombian dental services from March 2019 to now, but its magnitude is unknown. Objective. To determine dental care coverage in Colombia during the pandemic period and compare these data with the pre-pandemic period 2017-2019. Methods. Dental coverage and consultation services registered in the "Sistema Integrado de Protección Social" or SISPRO from 2017 to 2021 were analyzed. Results. The whole dental service coverage rate was nearly 20% before Covid-19 pandemic and even registered a slight increase from 2017 to 2018 at national and at department levels. This dental national coverage was 31,14% for every 100 habitants in 2019. However, there was a sharp reduction to 17% in 2020 and to 9% in 2021, revealing a clear and negative impact of the pandemic in dental coverage services and in dental emergency services. Conclusion. A decrease in dental coverage during to the COVID-19 pandemic is revealed, with a concomitant reduction in dental emergency consultations during 2020 and 2021 at country level. The consequences of this disruption on the oral and dental epidemiological profile of Colombians is still unknown and might require urgent preventive, promotional and curative care actions to recover the pre-pandemic dental coverage levels.

¿Debemos seguir considerando el monto isquémico en los síndromes coronarios crónicos? / Should We Continue to Consider Extent of Ischemic Myocardium in Chronic Coronary Syndromes?

RESUMEN El surgimiento de nueva evidencia científica en los últimos años en relación con los síndromes coronarios crónicos (SCC) lleva a reconsiderar las recomendaciones diagnósticas y terapéuticas que históricamente guiaron nuestra práctica médica. Sin embargo, es importante destacar que gran parte de la información difundida carece de un análisis crítico riguroso, lo que nos expone al riesgo de incorporar nuevos algoritmos en la práctica clínica que podrían no ser completamente aplicables a nuestra población. En esta revisión se analiza la literatura científica disponible relacionada a los SCC, para tratar de establecer si realmente el monto isquémico carece de significado clínico y pronóstico tal como se afirma en algunas publicaciones.

ABSTRACT In the last years, new scientific evidence related to chronic coronary syndromes (CCS) has led to reconsider the diagnostic and therapeutic recommendations that historically guided our medical practice. However, it is important to point out that the disseminated information lacks a precise critical analysis, with the risk of incorporating new algorithms in clinical practice that might not be completely applicable to our population. The present review analyses the available scientific CCS literature to establish whether the extent of ischemic myocardium has no real clinical and prognostic significance as reported in some publications.

Poly sensibilisation dans le cadre d'un eczéma de contact des mains chez une aide-ménagère dans le nord du Bénin / Poly sensitization in the context of hand contact eczema in a household helper in northern Benin

L'eczéma des mains est fréquent. Son étiologie est souvent multifactorielle comprenant les facteurs environnementaux et des facteurs individuels prédisposants. Il pose des problèmes de diagnostic étiologique en particulier dans un contexte de poly sensibilisation. Observation Il s'est agi d'une employée de maison âgée de 17 ans sans antécédents allergiques connus. Elle a développé un eczéma bilatéral des mains six mois après embauche. Le patch test avec la batterie standard européenne a montré une poly sensibilisation à plusieurs allergènes contenus dans les détergents et désinfectants. Le patch test aux gants est revenu négatif mais n'exclut pas son implication dans la survenue des lésions devant le caractère bilatéral et symétrique des lésions. Une réorientation professionnelle a été proposée devant le jeune âge de la travailleuse Conclusion La connaissance des allergènes en cause au cours d'un eczéma est un atout pour une meilleure prise en charge du patient mais leur identification n'est pas toujours aisée. La réorientation professionnelle lorsqu'elle est possible assure la guérison.

Introduction: Hand eczema is common. Its etiology is often multifactorial, including environmental factors and individual predisposing factors. It poses problems of etiological diagnosis, particularly in the context of poly sensitization. Observation: This case involved a 17-year-old domestic worker with no known allergic history. She developed bilateral hand eczema six months after hiring. The patch test with the standard European battery showed poly-sensitization to several allergens contained in detergents and disinfectants. The glove patch test came back negative, but did not rule out its involvement in the lesions, given the bilateral and symmetrical nature of the lesions. In view of the young age of the worker, a vocational reorientation was carried out. Conclusion: Knowledge of the allergens involved in eczema is an asset for better patient management, but identifying them is not always easy. When possible, professional reorientation ensures recovery

Mechanism and experimental validation of Zukamu granules in treatment of bronchial asthma based on network pharmacology and molecular docking / 中国药理学通报

Aim To anticipate the mechanism of zuka- mu granules (ZKMG) in the treatment of bronchial asthma, and to confirm the projected outcomes through in vivo tests via using network pharmacology and molecular docking technology. Methods The database was examined for ZKMG targets, active substances, and prospective targets for bronchial asthma. The protein protein interaction network diagram (PPI) and the medication component target network were created using ZKMG and the intersection targets of bronchial asthma. The Kyoto Encyclopedia of Genes and Genomics (KEGG) and gene ontology (GO) were used for enrichment analysis, and network pharmacology findings were used for molecular docking, ovalbumin (OVA) intraperitoneal injection was used to create a bronchial asthma model, and in vivo tests were used to confirm how ZKMG affected bronchial asthma. Results There were 176 key targets for ZKMG's treatment of bronchial asthma, most of which involved biological processes like signal transduction, negative regulation of apoptotic processes, and angiogenesis. ZKMG contained 194 potentially active components, including quercetin, kaempferol, luteolin, and other important components. Via signaling pathways such TNF, vascular endothelial growth factor A (VEGFA), cancer pathway, and MAPK, they had therapeutic effects on bronchial asthma. Conclusion Key components had strong binding activity with appropriate targets, according to molecular docking data. In vivo tests showed that ZKMG could reduce p-p38, p-ERKl/2, and p-I

Fluoride in drinking groundwater and prevalence of fluorosis in children and adolescents: A systematic review / Fluoruro en el agua subterránea potable y prevalencia de fluorosis en niños y adolescentes: Una revisión sistemática

ABSTRACT Fluorosis is a worldwide public health problem. One of the factors related to it is the type of water consumed, such as groundwater. High fluoride concentration in groundwater may be explained by contamination from local industries. Since fluoride and arsenic are the main pollutants of groundwater, some studies correlate groundwater consumption with high prevalence of fluorosis Aim The aim of this study was to conduct a systematic review to determine whether children's risk of fluorosis is related to drinking groundwater Materials and Method The protocol for this systematic review was registered at the National Institute of Health Research Database (CRD42021227298). A comprehensive search was conducted to identify potentially relevant studies by exploring a range of electronic databases (Medline via PubMed, Scopus, Cochrane Library, Science Direct, Web of Science Core Collection, Medline via Ovid, Lilacs, Embase, and grey literature) Results A total 2189 articles were found. After reading titles and abstracts, 63 were selected for screening, and the final data was extracted from 15 articles Conclusion A relationship was identified between drinking fluoridated water from wells and the prevalence of fluorosis in individuals up to 18 years old. This is the first study to assess the issue systematically worldwide.

RESUMEN La fluorosis es un problema de salud pública a nivel mundial y el tipo de agua consumida es uno de los factores relacionados con ella, como el consumo de aguas subterráneas. La alta concentración de fluoruro en estas aguas puede justificarse por la contaminación por industrias locales y las características del suelo, donde algunos estudios correlacionan el consumo de aguas subterráneas con una alta prevalencia de fluorosis, ya que el fluoruro, junto con el arsénico, se consideran los principales contaminantes de estas aguas Objetivo El objetivo es realizar una revisión sistemática que relacione el riesgo de fluorosis en niños expuestos al consumo de agua procedente de pozos Materiales y Método El protocolo de esta revisión sistemática fue registrado en el National Institute of Health Research Database (CRD42021227298). Se realizó una búsqueda bibliográfica de estudios primarios explorando diversas bases de datos electrónicas (Medline vía PubMed, Scopus, Cochrane Library, Science Direct, Web of Science Core Collection, Medline vía Ovid, Lilacs, Embase y literatura gris) Resultados Se encontraron 2189 artículos, tras la lectura de títulos y resúmenes se seleccionaron 63 referencias para examinar y, finalmente, se extrajeron los datos de 15 artículos Conclusiones Se identificó una relación entre el consumo de agua fluorada de pozo y la prevalencia de fluorosis en individuos de hasta 18 años, siendo este estudio el primero en evaluarlo sistemáticamente a nivel mundial.

Radios comunitarias, alternativas y populares en la provincia de san luis, argentina: condiciones, trayectorias y estrategias

Este trabajo busca indagar características y prácticas comunicacionales particulares de radios comunitarias, alternativas y populares (CAP) en la provincia de San Luis (Argentina) en el período 20102020, de acuerdo con la normativa vigente desde la sanción de la Ley 26.522. En San Luis se pueden reconocer tres radios CAP: La Bulla, Radio Masi y Radio Rebelde, todas ellas surgieron después de la sanción de la ley. La metodología es cualitativa e incluye consulta de registros, relevamientos previos, publicaciones académicas, entrevistas y conversaciones informales con miembros de los medios. Se propone analizar qué prácticas comunicacionales se despliegan a fin de construir sostenibilidad y en qué medida lo consiguen. También se incluye el estudio respecto a cómo relacionan con otros actores sociales relevantes como el Estado, en sus tres niveles, medios, organizaciones de la sociedad civil y la comunidad, en un sistema infocomunicacional caracterizado por la concentración y centralización. Las radios comunitarias de San Luis sintieron las repercusiones de los cambios de gestión a nivel nacional, y la parálisis en las políticas de comunicación de la provincia, pero aun así continúan al aire. Sin embargo, la falta de nuevas experiencias de comunicación comunitaria invitan a reflexionar sobre las condiciones sociopolíticas que contribuyen a perpetuar su marginalidad en el ecosistema de medios de la provincia.

This article aims to describe characteristics andcommunicational practices of community, alternative, and popular radio stations in San Luis Province, Argentina, between 2010 and 2020, considering the latest regulation in force: LSCA law 26.522, 2009. In San Luis, there are three radio stations that fall under the categories of community, alternative, and popular, according to the law: La Bulla, Masi Radio, and Radio Rebelde, all of them born after the law was sanctioned. The methodology is qualitative, and the analysis is based on empirical research that includes official registries, previous research, academic papers, interviews, and informal conversations with media members. The study analyzes the practices that these radio stations develop to build sustainability, and whether or not they achieve it. Their relationship to other socially relevant actors, such as the State in its three levels, other civil organizations, within a concentrated and centralized media system, is also considered, reflecting those characteristics from the province's political power configuration. Community radios in San Luis suffered the consequences of the national government changes and the paralysis in local communication policies, nevertheless, they are still operative. However, the lack of new community experiences requires further thoughts about how social and political conditions contribute to its marginal position in the communicational system of the province.

Assessment of functional outcome following Duhamel retro-rectal pull-through surgery for Hirschsprung's disease: a follow-up study

Context: Hirschsprung's disease (HD) is one of the commonest problems requiring surgery in children. More than 95% of children present during new-born period, when they are treated with leveling colostomy and are followed with pull-through surgery a few months later, once the child has gained adequate weight to withstand a major surgery. The commonest pull through surgery done is the Duhamel retro-rectal pull-through (DRPT) repair. Settings and Design: This is a retrospective study of children who presented to one unit in our institute, a tertiary care referral hospital for children less than 12 years, with HD and underwent DRPT procedure during the period between July 2017 to June 2020. The children were evaluated after three years of follow-up for fecal incontinence and constipation. The study was conducted in children diagnosed with classical segment recto-sigmoid HD who underwent surgery. The children who were diagnosed with HD other than classical segment, who underwent primary pull through surgery and who underwent other repairs for HD were excluded from the study. Results: Thirty-two children underwent DRPT procedure during the study period. Of them, five (15.6%) children were lost on follow-up and one (3.1%) child had expired in the immediate post-operative period. Twenty-six children were included in the study. The bowel function score was calculated. The mean age of definitive surgery was 4.2 years. The follow-up period was a minimum of three years. Only two children had a "good" score of eighteen and above. Nineteen children had a "fair" score of 13-17. Five children had a "poor" score of less than thirteen, and among them, two had a "very poor" score of less than nine. The mean BFS was 13.72. Conclusions: Functional outcomes following Duhamel procedure are satisfactory, with 7.7% of children are in the fringe of requiring another surgery for constipation and pseudo-incontinence. (AU)

Ações para o controle do câncer do colo do útero na Atenção Primária à Saúde (APS) do Município do Rio de Janeiro / Actions to control cervical cancer in Primary Health Care (PHC) in the City of Rio de Janeiro

O presente estudo descreve o panorama do Estado e Município do Rio de Janeiro relativo ao rastreamento para o câncer do colo do útero, os resultados de exames citopatológicos e o seguimento das mulheres registrados no Sistema de Informação do Câncer (SISCAN) no período de 2015 a 2022. O estudo ressalta a importância da atenção primária à saúde nas ações para o controle efetivo e a prevenção do câncer do colo do útero na população. A metodologia utiliza o levantamento do referencial teórico através da análise das produções bibliográficas encontradas na literatura para contextualização temática do estudo, a utilização de dados secundários e a obtenção dos achados disponibilizados no SISCAN com relação aos registros dos laudos de exames citopatológicos realizados pelas mulheres no período de análise do estudo. Como resultados, foi possível identificar falhas de registro, baixo número de exames e fragilidades para o gerenciamento do sistema de informação pela gestão estadual e municipal. Com os resultados preliminares, foi necessário analisar a produção de exames citopatológicos no Sistema de Informação ambulatorial (SIA) para subsidiar as discussões e hipóteses para o encontrado, como a baixa produção de exames citopatológicos e o sub-registro no SISCAN no Estado e Município do Rio de Janeiro. Considera-se que existe a necessidade urgente de uma reorganização dos serviços locais para implementar as ações do rastreamento para o câncer do colo do útero, incluindo a garantia do acesso para detecção precoce e o acompanhamento das mulheres encaminhadas a outros níveis de atenção da rede para confirmação diagnóstica, acompanhamento e tratamento. Ressalta-se a importância de assegurar a integralidade das ações para o controle efetivo do câncer do colo do útero em todo o Estado e Município do Rio de Janeiro. (AU)

The present case study describes an analysis of cytopathological exam reports registered in the Cancer Information System (SISCAN) from 2015 to 2022 in the Municipality and State of Rio de Janeiro. Above all, the study seeks to highlight the importance of primary health care in actions to control and prevent cervical cancer. The methodology used to develop the study consists of surveying the theoretical framework through the analysis of bibliographical productions found for the thematic contextualization of the study and the use of a secondary database and obtaining possible findings in SISCAN on the records of exam reports cytopathological. In this sense, it was possible to identify registration flaws, a low number of exams and weaknesses in the management of the information system by state and municipal management. In view of this, it was necessary to analyze the production of cytopathological exams in the outpatient Information System (SIA) to support discussions and hypotheses of the results found, such as the high incidence and mortality from cervical cancer, the low production of cytopathological exams and under-registration in SISCAN in the State and Municipality of Rio de Janeiro. Concluding, therefore, the urgent and imminent need for the organization of local services to implement organized screening actions for cervical cancer, including ensuring access to early detection and monitoring of women referred to other levels of care in the network for diagnostic confirmation and treatment. Therefore, ensure the completeness of cervical cancer control actions throughout the State and Municipality of Rio de Janeiro. (AU)
