Prevalencia de anomalías dentomaxilares y necesidad de tratamiento de ortodoncia en niñas/os de 6 años en cinco comunas de Chile. Estudio Preliminar

Objetivo: Determinar la prevalencia de las anomalías dentomaxilares (ADM) y necesidad de tratamiento de ortodoncia en escolares de 6 años en cinco comunas en Chile. Material y método: Estudio de corte transversal, observacional y descriptivo. La muestra fue de 1102 escolares. Se realizaron exámenes clínicos aplicando la Guía de Referencia Clínica a Ortodoncia para Servicios Públicos de Salud, para determinar la prevalencia de las ADM y necesidad de tratamiento de ortodoncia. El análisis estadístico utilizó el programa STATA®, considerando estadísticamente significativo p 0.05. Resultados: 1102 escolares de 6 años fueron examinados, 48,8% niñas y 51,2% niños. La prevalencia de niño/as con anomalías dentomaxilares fue 59.1%. Las tres más prevalentes fueron: apiñamiento dentario o rotaciones (21,6%), resalte aumentado (17,6%) y overbite aumentado (15,9%). La necesidad de tratamiento de ortodoncia encontrada fue de 34,7% con evidente necesidad y un 25,3% con leve necesidad. Conclusión: Se evidencia la necesidad de incluir en las políticas públicas de salud oral, estrategias de diagnóstico y tratamiento temprano de ADM por su alta prevalencia.

Objective: To determine the prevalence of dento-maxillary anomalies (DMA) and the orthodontic treatment need in 6-year-old schoolchildren in five areas of Chile. Material and method: Cross-sectional, observational and descriptive study. The sample consisted of 1102 6-year-old schoolchildren. Clinical examinations were carried out applying the Clinical Reference Guide for Orthodontics in Public Health Services, to determine the prevalence of DMA and the need for orthodontic treatment. Statistical analysis used the STATA® program, considering p ≤ 0.05 statistically significant. Results: 1102 6-year-old children were examined, 48.8% were girls and 51.2% boys. The prevalence of children with DMA was 59.1%. The three most prevalent were: dental crowding or rotations (21.6%), increased overjet (17.6%), and increased overbite (15.9%). The orthodontic treatment need was 34.7% of patients with great need and 25.3% with moderate need. Conclusion: The need to include early diagnosis and treatment strategies for DMA in public oral health policies is evident due to its high prevalence.

Postoperative intensive care allocation and mortality in high-risk surgical patients: evidence from a low- and middle-income country cohort.

BACKGROUND: The escalation of surgeries for high-risk patients in Low- and Middle-Income Countries (LMICs) lacks evidence on the positive impact of Intensive Care Unit (ICU) admission and lacks universal criteria for allocation. This study explores the link between postoperative ICU allocation and mortality in high-risk patients within a LMIC. Additionally, it assesses the Ex-Care risk model's utility in guiding postoperative allocation decisions. METHODS: A secondary analysis was conducted in a cohort of high-risk surgical patients from a 800-bed university-affiliated teaching hospital in Southern Brazil (July 2017 to January 2020). Inclusion criteria encompassed 1431 inpatients with Ex-Care Model-assessed all-cause postoperative 30-day mortality risk exceeding 5%. The study compared 30-day mortality outcomes between those allocated to the ICU and the Postanesthetic Care Unit (PACU). Outcomes were also assessed based on Ex-Care risk model classes. RESULTS: Among 1431 high-risk patients, 250 (17.47%) were directed to the ICU, resulting in 28% in-hospital 30-day mortality, compared to 8.9% in the PACU. However, ICU allocation showed no independent effect on mortality (RR = 0.91; 95% CI 0.68‒1.20). Patients in the highest Ex-Care risk class (Class IV) exhibited a substantial association with mortality (RR = 2.11; 95% CI 1.54-2.90) and were more frequently admitted to the ICU (23.3% vs. 13.1%). CONCLUSION: Patients in the highest Ex-Care risk class and those with complications faced elevated mortality risk, irrespective of allocation. Addressing the unmet need for adaptable postoperative care for high-risk patients outside the ICU is crucial in LMICs. Further research is essential to refine criteria and elucidate the utility of risk assessment tools like the Ex-Care model in assisting allocation decisions.

Patient Repositioning during Hospitalization and Prevention of Pressure Ulcers: a Narrative Review / Reposicionamiento de pacientes en hospitalización y prevención de úlceras por presión: una revisión narrativa / Reposicionamento de pacientes na internação e prevenção de úlceras por pressão: uma revisão narrativa

Objective. This article presents a literature review to explore and analyze the current situation of pressure ulcers or lesions or decubitus ulcers, pathophysiological, epidemiological aspects, and risk factors. The progress in evidence of the effectiveness of preventive repositioning in the appearance of these lesions in vulnerable hospitalized patients is also evaluated. Methods. Databases were reviewed in non-systematic manner, including the Cochrane Wounds Specialized Register; Medline, Scopus, PubMed, the Cochrane Central Register of Controlled Trials; MEDLINE (Ovid); EMBASE (Ovid), Web of Science, SciELO, and Lilacs. The general search terms included [pressure ulcers or pressure lesions or decubitus ulcers] and [prevention or preventive] and [repositioning or positioning or position changes or postural change] and [patient at risk or vulnerable] and [hospitalized or ICU or intensive care]. Systematic literature reviews, randomized clinical trials, observational studies, cost-effectiveness and qualitative studies in English or Spanish were included. Results. Although globally, the incidence, prevalence, and years of disability associated to these lesions has diminished between 1990 and 2019, the high impact on health persists. Evidence found on the effectiveness of repositioning in preventing pressure ulcers and health associated costs has been evaluated with certainty between low and very low, as a result of conducting research with serious methodological limitations that report results with high inaccuracy. Conclusion.The findings reported present that these lesions persist at hospital level and continue being a global social and health problem with high impact on health budgets. Likewise, there is a need to develop greater quality research on prevention strategies, such as repositioning, which validate their effectiveness, and justify their use.

Effectiveness of a Nursing Educational Intervention in Adults to Promote Control Behaviors Against Dengue: Protocol for a Randomized Controlled Trial.

BACKGROUND: The increase in dengue cases can be attributed to social, demographic, environmental changes, or community-driven factors. In this regard, different strategies have been established in health education, using educational interventions as necessary tools for the reduction of the disease with the aim of reinforcing and stimulating the prevention and control of dengue. OBJECTIVE: This study aims to evaluate the effectiveness of a nursing educational intervention for dengue control. METHODS: A randomized controlled trial will be conducted with adults living in rural areas and participating in health promotion and disease prevention programs. We will enroll 116 adults. Adults will be randomized 1:1, with 58 adults assigned to the educational intervention group and 58 to the usual care group. Participants will receive 4 sessions over the course of a month, 1 week apart, and will be followed up for 1 month after the end of the educational intervention. Nursing Outcome Classification labels will be used to measure the outcomes: risk control (1902) and participation in health care decisions (1606). RESULTS: The participants in the intervention group are expected to achieve better dengue control behaviors than those in the usual care group. CONCLUSIONS: Risk factors are fostered by the community, largely caused by artificial reservoirs or unprotected tanks in homes; also, the lack of information hinders the identification of symptomatology and the poor implementation of effective measures, and the development of standardized educational strategies can contribute to efficient and cost-effective control of the disease. TRIAL REGISTRATION: ClinicalTrials.gov NCT05321264; https://clinicaltrials.gov/study/NCT05321264. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): PRR1-10.2196/54286.

Brazilian Thoracic Society recommendations for the diagnosis and monitoring of asbestos-exposed individuals

ABSTRACT Asbestos was largely used in Brazil. It is a mineral that induces pleural and pulmonary fibrosis, and it is a potent carcinogen. Our objective was to develop recommendations for the performance of adequate imaging tests for screening asbestos-related diseases. We searched peer-reviewed publications, national and international technical documents, and specialists' opinions on the theme. Based on that, the major recommendations are: Individuals exposed to asbestos at the workplace for ≥ 1 year or those with a history of environmental exposure for at least 5 years, all of those with a latency period > 20 years from the date of initial exposure, should initially undego HRCT of the chest for investigation. Individuals with pleural disease and/or asbestosis should be considered for regular lung cancer monitoring. Risk calculators should be adopted for lung cancer screening, with a risk estimate of 1.5%.

Proposal of a new slit-lamp shield for ophthalmic examination and assessment of its effectiveness using computational simulations / Avaliação da eficácia e proposta de um novo protetor de lâmpada de fenda durante exame oftálmico por meio de simulações computacionais

ABSTRACT Purpose: This study aimed to use computational models for simulating the movement of respiratory droplets when assessing the efficacy of standard slit-lamp shield versus a new shield designed for increased clinician comfort as well as adequate protection. Methods: Simulations were performed using the commercial software Star-CCM+. Respiratory droplets were assumed to be 100% water in volume fraction with particle diameter distribution represented by a geometric mean of 74.4 (±1.5 standard deviation) μm over a 4-min duration. The total mass of respiratory droplets expelled from patients' mouths and droplet accumulation on the manikin were measured under the following three conditions: with no slit-lamp shield, using the standard slit-lamp shield, and using our new proposed shield. Results: The total accumulated water droplet mass (kilogram) and percentage of expelled mass accumulated on the shield under the three aforementioned conditions were as follows: 5.84e-10 kg (28% of the total weight of particle emitted that settled on the manikin), 9.14e-13 kg (0.045%), and 3.19e-13 (0.015%), respectively. The standard shield could shield off 99.83% of the particles that would otherwise be deposited on the manikin, which is comparable to 99.95% for the proposed design. Conclusion: Slit-lamp shields are effective infection control tools against respiratory droplets. The proposed shield showed comparable effectiveness compared with conventional slit-lamp shields, but with potentially enhanced ergonomics for ophthalmologists during slit-lamp examinations.

RESUMO Introdução: Os oftalmologistas têm alto risco de contrair a doença do Coronavírus-19 devido à proximidade com os pacientes durante os exames com lâmpada de fenda. Usamos um modelo de computação para avaliar a eficácia das proteções para lâmpadas de fenda e propusemos uma nova proteção ergonomicamente projetada. Métodos: As simulações foram realizadas no software comercial Star-CCM +. Os aerossóis de gotículas foram considerados 100% de água em fração de volume com distribuição de diâmetro de partícula representada por uma média geométrica de 74,4 ± 1,5 (desvio padrão) μm ao longo de uma duração de quatro minutos. A massa total de gotículas de água acumulada no manequim e a massa expelida pela boca do paciente foram medidas em três condições diferentes: 1) Sem protetor de lâmpada de fenda, 2) com protetor padrão, 3) Com o novo protetor proposto. Resultados: A massa total acumulada das gotas de água (kg) e a porcentagem da massa expelida acumulada no escudo para cada uma das respectivas condições foram; 1) 5,84e-10 kg (28% do peso total da partícula emitida que assentou no manequim), 2) 9,14e-13 kg (0,045%), 3,19e-13 (0,015%). O escudo padrão foi capaz de proteger 99,83% das partículas que, de outra forma, teriam se depositado no manequim, o que é semelhante a 99,95% para o projeto proposto. Conclusão: Protetores com lâmpada de fenda são ferramentas eficazes de controle de infecção contra gotículas respiratórias. O protetor proposto mostrou eficácia comparável em comparação com os protetores de lâmpada de fenda convencionais, mas potencialmente oferece uma melhor ergonomia para oftalmologistas durante o exame de lâmpada de fenda.

COVID-19 en Chile: análisis de su impacto por olas y regiones / The impact of the different waves of COVID-19 pandemic in Chile across regions

BACKGROUND: The effects of COVID-19 in Chile changed over time and among regions. Aim: To identify patterns in the impact and evolution of COVID-19 for each wave generated between 2020 and 2022 at the 16 regions of the country. MATERIAL AND METHODS: Several indicators related to the pandemic, their evolution and their consequences for the health system and the health of the population were calculated. RESULTS: There are differences in the evolution of the infection across the regions of the country, as well as heterogeneity between waves. Specifically, the second wave in Chile was identified as the one with the greatest impact, with a national death rate of 123.5 deaths per 100,000 inhabitants and 66.4% intensive care unit occupancy rate due to COVID-19. Performing a geographic analysis, it was possible to find systematic patterns, for example, between regions with higher immunization rates and lower rates of lethality, such as the cases of Ñuble and Atacama regions. Conclusions: These results emphasize the need to consider regional differences and the temporal context for the elaboration of strategies to the efficient management of a pandemic.

A nationwide pilot study on breast cancer screening in Peru.

Introduction: A high prevalence of advanced breast cancer (BC) is a common scenario in Latin America. In Peru, the frequency of BC at Stages III/IV is ≈50% despite implementation of a programme for breast cancer screening (BCS) along the country. We carried out a study to assess the feasibility and develop an instrument to evaluate the knowledge, barriers and perception about BCS in a nationwide pilot study in Peru among candidates for BCS. Methods: We conducted a systematic review of 2,558 reports indexed in PubMed, Scopus, Web of Science, Medline-Ovid and EMBASE, regarding to our study theme. In total, 111 were selected and a 51-items survey was developed (eight items about sociodemographic characteristics). Patients were recruited in public hospitals or private clinics, in rural and urban areas of nine departments of Peru. Results: We surveyed 488 women from: Lima (150), Cajamarca (93), Ica (59), Arequipa (56), Loreto (48), Ancash (38), Junín (15), Puerto Maldonado (15) and Huancavelica (14); 27.9% of them were from rural areas. The mean of age was 53.3 years (standard deviation ± 9.1). Regarding education level, 29.8% had primary, 33.2% secondary and 37.0% higher education. In total, 28.7% of women did not know the term 'mammogram' and 47.1% reported never receiving a BCS (36.9% from urban and 73.5% from rural population). In women that underwent BCS, only 67% knew it is for healthy women. In total, 54.1% of patients had low levels of knowledge about risk factors for BC (i.e. 87.5% of women respond that injuries in the breast produce cancer). Cultural, economic and geographic barriers were significantly associated with having a mammogram where 56.9% of participants considered a cost ≤ 7 USD as appropriate. Mammogram was perceived as too painful for 54.9% of women. In addition, women with a self-perception of low-risk for BC and a fatalistic perception of cancer were less likely to have a BCS. Conclusion: We found that it is feasible to conduct a large-scale study in Peru. The results of this pilot study highlight an urgent need of extensive education and awareness about BCS in Peru.

Importancia de la prevención y detección oportuna de la preeclampsia/eclampsia / Importance of prevention and timely detection of preeclampsia/eclampsia

La preeclampsia/eclampsia constituyen una manifestación de la enfermedad hipertensiva que se puede presentar después de la semana 20 del embarazo. Esta tiene la capacidad de generar múltiples complicaciones en la gestante y el feto. Su diagnóstico oportuno y la toma de medidas preventivas ante sus factores de riesgo tienen la potencialidad para reducir la morbimortalidad por esta causa.

Preeclampsia/eclampsia is a manifestation of a hypertensive disease that can occur after the 20th week of pregnancy by generating multiple complications in the pregnant woman and the fetus. Its timely diagnosis and the taking of preventive measures against its risk factors can reduce morbidity and mortality.

Migration and medical screening for tuberculosis / Imigração e triagem médica para tuberculose

ABSTRACT Vulnerable populations, such as migrants and refugees, have an increased risk of tuberculosis disease, especially in the first years after arrival in the host country. The presence of migrants and refugees in Brazil exponentially grew over the period between 2011 and 2020, and approximately 1.3 million migrants from the Global South were estimated to be residing in Brazil, most of whom from Venezuela and Haiti. Tuberculosis control programs for migrants can be divided into pre- and post-migration screening strategies. Pre-migration screening aims to identify cases of tuberculosis infection (TBI) and can be carried out in the country of origin (pre-entry) or in the destination country (at entry). Pre-migration screening can also detect migrants at an increased risk of developing tuberculosis in the future. High-risk migrants are then followed up in post-migration screening. In Brazil, migrants are considered a priority group for the active search for tuberculosis cases. However, there is no recommendation or plan regarding screening for TBI in migrants and refugees. Ensuring prevention, diagnosis, and treatment for TBI and tuberculosis disease in migrant populations is an important aspect of tuberculosis control and elimination. In this review article, we address epidemiological aspects and access to health care for migrants in Brazil. In addition, the migration medical screening for tuberculosis was reviewed.

RESUMO Populações vulneráveis, como imigrantes e refugiados, apresentam maior risco de tuberculose doença, especialmente nos primeiros anos após a chegada ao país de acolhimento. A presença de imigrantes e refugiados no Brasil cresceu exponencialmente no período entre 2011 e 2020, sendo estimado que aproximadamente 1,3 milhão de imigrantes do Sul Global residiam no Brasil, a maioria proveniente da Venezuela e do Haiti. Os programas de controle da tuberculose para imigrantes podem ser divididos em estratégias de triagem pré- e pós-migração. A triagem pré-migração visa identificar casos de tuberculose infecção (TBI) e pode ser realizada no país de origem (pré-entrada) ou no país de destino (no momento da entrada). A triagem pré-migração também pode detectar imigrantes com maior risco de desenvolver tuberculose no futuro. Os imigrantes de alto risco são então acompanhados na triagem pós-migração. No Brasil, os imigrantes são considerados um grupo prioritário para a busca ativa de casos de tuberculose. No entanto, não há recomendação ou plano sobre triagem para TBI em imigrantes e refugiados. Garantir a prevenção, o diagnóstico e o tratamento da TBI e da tuberculose doença em populações imigrantes é um aspecto importante do controle e eliminação da tuberculose. Neste artigo de revisão, abordamos aspectos epidemiológicos e acesso à saúde para imigrantes no Brasil. Além disso, revisou-se a triagem médica de imigrantes para tuberculose.

Modelo general de la determinación social de la salud para la tuberculosis

Introducción : El avance hacia la eliminación de la tuberculosis en Cuba, depende de la justicia social para las personas afectadas y sus familiares, barrio por barrio, área de salud por área de salud y municipio por municipio. Para potenciar las dimensiones de su determinación social será necesario un modelo de eliminación local asentado en su enfoque general. Objetivo : Describir un modelo general con enfoque sistémico de la determinación social en salud, aplicado a la tuberculosis. Métodos : Se realizó un estudio cualitativo basado en una revisión documental de artículos sobre la determinación social, con diseño de un modelo explicativo, simple para su comprensión, con componentes estructurales, intermedios e individuales para ser adaptado en el tema de la tuberculosis. Resultados : El modelo planteado tiene como entrada la voluntad política, dependiente del poder establecido que determina las políticas públicas, interactuando con las dimensiones intermedias como aspectos centrales y con las dimensiones individuales de carácter sociodemográficas, socioculturales y socioeconómicas. Estas a su vez retroalimentan e influyen nuevamente en la Voluntad política y las Políticas públicas, cerrando el ciclo sistémico. Además, se incluye el control interactivo del sistema. Conclusiones : Además de los modelos planteados en la literatura nacional revisada, abundar en su enfoque sistémico contribuye a facilitar la comprensión del monitoreo de la Determinación social de la tuberculosis por parte del personal encargado de dar sostenibilidad del control hacia la eliminación.

Introduction : Progress towards the tuberculosis elimination in Cuba depends on social justice for the people affected and their families, neighborhood by neighborhood, health area by health area and municipality by municipality. To enhance the dimensions of its social determination, a local elimination model based on its general approach will be necessary. Objective: To describe a general model with a systemic approach to Social determination in health, applied to tuberculosis. Methods : A qualitative study based on a documentary review of articles on social determination was carried out, with the design of an explanatory model, simple for its understanding, with structural, intermediate and individual components to be adapted to the topic of tuberculosis. Results : The proposed model has as input the political will, dependent on the established power that determines public policies, interacting with the intermediate dimensions as central aspects and with the individual dimensions of a sociodemographic, sociocultural and socioeconomic nature. These, in turn, feedback and once again influence the political will and Public policies, closing the systemic cycle. In addition, interactive control of the system is included. Conclusions : In addition to the models proposed in the national literature reviewed, abounding in its systemic approach contributes to facilitate the understanding of the monitoring of the Social determination in health in tuberculosis by the personnel in charge of providing sustainability of control towards elimination.

Importance of vaccination against human papillomavirus in a rural settlement in Terenos, Mato Grosso do Sul / Importância da vacinação contra o papilomavírus humano em um assentamento rural em Terenos, Mato Grosso do Sul

ABSTRACT OBJECTIVE To understand health professionals' perceptions about vaccination against human papillomavirus (HPV) in the Santa Mônica rural settlement in Terenos, Mato Grosso do Sul. METHODS Quantitative and qualitative methodologies, consultations on vaccination cards, records of community health agents and the focus group technique were used. The main factors of hesitation and vaccine refusal were analyzed, as well as the health team's strategies for the process of immunization against HPV, from June to August 2018. RESULTS Of 121 children and adolescents, 81 (66.94%) received the complete vaccination schedule. Complete vaccination coverage for women was 73.17% (60/82) and for men, 53.8% (21/39). It was observed that, although strategies are adopted for vaccine promotion, such as mobile actions, the public is resistant due to superficial knowledge about the vaccine and its use in an early age group, showing itself to be susceptible to the negative influence of the media and to society's taboos. In addition, difficulties regarding the use of the Unified Health System card and the shortage of professionals were also observed. CONCLUSION The results explain the immunization coverage below the target and reinforce the need to strengthen the family health strategy, as well as the permanent and continuing education of professionals, in order to increase parental confidence and adherence to vaccination.

RESUMO OBJETIVO Compreender as percepções dos profissionais de saúde acerca da vacinação contra o papilomavírus humano (HPV) no Complexo de assentamentos Santa Mônica, em Terenos, Mato Grosso do Sul. MÉTODOS Foram utilizadas metodologias quanti-qualitativas, consultas em cartões vacinais, registros de agente comunitários de saúde e a técnica de grupo focal. Foram analisados os principais fatores de hesitação e recusa vacinal, bem como as estratégias da equipe de saúde para o processo de imunização contra o HPV, de junho a agosto de 2018. RESULTADOS De 121 crianças e adolescentes, 81 (66,94%) receberam o esquema vacinal completo. A cobertura vacinal completa feminina foi de 73,17% (60/82) e a masculina de 53,8% (21/39). Observou-se que, embora sejam adotadas estratégias para a promoção da vacina, como ações volantes, o público encontra-se resistente devido ao conhecimento superficial sobre a vacina e sua utilização em faixa etária precoce, mostrando-se suscetível à influência negativa da mídia e aos tabus da sociedade. Além disso, dificuldades quanto ao uso do cartão do Sistema Único de Saúde e a escassez de profissionais também foram observadas. CONCLUSÃO Os resultados justificam a cobertura vacinal abaixo da meta e reforçam a necessidade de fortalecimento da estratégia de saúde da família, bem como da educação permanente e continuada dos profissionais, a fim de aumentar a confiança dos pais e a adesão à vacinação.

Factors of abandonment of tuberculosis treatment in the public health network / Factores de abandono al tratamiento de la tuberculosis en la red pública de salud

ABSTRACT This study determines the factors of abandonment of tuberculosis treatment in the public health network of Cali, Colombia, during years 2016 to 2018. We conducted an operational case-control investigation including 224 patients with tuberculosis (112 abandoned treatment and 112 completed it). We found that treatment abandonment for tuberculosis is driven by factors related to the individuals and health services that facilitate non-adherence and drive them away from the care provided in medical institutions.

RESUMEN Este estudio determina los factores de abandono al tratamiento de la tuberculosis en la red pública de salud de Cali, Colombia, durante los años 2016 a 2018. Se realizó una investigación operativa de casos y controles en la que se incluyeron 224 pacientes con tuberculosis (112 abandonaron el tratamiento y 112 lograron completarlo). Se encuentra que el abandono del tratamiento para la tuberculosis está impulsado por factores relacionados con el individuo y los servicios de salud que facilitan la no adherencia y los alejan de la atención brindada en las instituciones médicas.

Advances in the Global Initiative for Childhood Cancer: implementation in Latin America and the Caribbean / Adelantos en la Iniciativa Mundial contra el Cáncer Infantil: aplicación en América Latina y el Caribe / Avanços na Iniciativa Global para o Câncer Infantil da OMS: implementação na América Latina e no Caribe

ABSTRACT This report describes the status of childhood cancer control initiatives in Latin America and the Caribbean (LAC). Progress between 2017 and 2023 is measured using the outcome indicators from the Pan American Health Organization (PAHO) childhood cancer logic model aligned with the World Health Organization Global Initiative for Childhood Cancer (GICC). This report also describes the advances, barriers, and facilitators for the implementation of the GICC at the Regional level. Methods used in this report encompassed a comprehensive approach, incorporating a literature review, interviews, surveys, and a Delphi study developed by the technical team of the PAHO Non-Communicable Diseases and Mental Health Department and by the GICC LAC working group. Since 2017, there has been a substantial increase in the number of countries that have included childhood cancer in their national regulations. Currently, 21 LAC countries are involved in the GICC implementation, activities, and dialogues. However, the objectives for 2030 will only be achieved if Member States overcome the barriers to accelerating the pace of initiative implementation. There is an urgent need to increase the efforts in childhood cancer control in LAC, especially regarding the prioritization of timely detection, essential diagnostics, access to cancer treatment, palliative care, and close follow-up of children and adolescents with cancer.

RESUMEN En este artículo se describe la situación de las iniciativas para el control del cáncer infantil en América Latina y el Caribe. Para medir los progresos entre el 2017 y el 2023, se utilizan los indicadores de resultados del modelo lógico del cáncer infantil de la Organización Panamericana de la Salud (OPS) que es coherente con la Iniciativa Mundial contra el Cáncer Infantil de la Organización Mundial de la Salud. También se describen los avances, los obstáculos y los elementos que han facilitado la aplicación de esa iniciativa en la Región Los métodos utilizados en este trabajo incluyeron un enfoque integral que incorporó una revisión bibliográfica, entrevistas, encuestas y un estudio de tipo Delfos llevado a cabo por el equipo técnico del Departamento de Enfermedades No Transmisibles y Salud Mental de la OPS y por el grupo de trabajo de América Latina y el Caribe de la Iniciativa Mundial contra el Cáncer Infantil de la Organización Mundial de la Salud. Desde el 2017 ha habido un incremento considerable en el número de países que incorporan el cáncer infantil en sus regulaciones nacionales. En la actualidad, 21 países de América Latina y el Caribe participan en la puesta en práctica, las actividades y las deliberaciones de la Iniciativa Mundial contra el Cáncer Infantil de la Organización Mundial de la Salud. No obstante, los objetivos para el 2030 solo podrán alcanzarse si los Estados Miembros son capaces de superar los obstáculos que dificultan la aceleración del ritmo de aplicación de esta iniciativa. Existe una necesidad urgente de aumentar las actividades dirigidas al control del cáncer infantil en América Latina y el Caribe, en especial en lo que respecta a priorizar la detección temprana, los medios de diagnóstico esenciales, el acceso a los tratamientos oncológicos, los cuidados paliativos y el seguimiento estricto de la población infantil y adolescente con cáncer.

RESUMO Este relatório descreve a situação das iniciativas de controle do câncer infantil na Região da América Latina e do Caribe (ALC). O progresso alcançado entre 2017 e 2023 foi medido usando os indicadores de resultados intermediários do modelo lógico de câncer infantil da Organização Pan-Americana da Saúde (OPAS), em linha com a Iniciativa Global para o Câncer Infantil (GICC) da Organização Mundial da Saúde. O relatório também descreve os avanços, as barreiras e os facilitadores para a implementação da iniciativa em nível regional. Os métodos utilizados neste relatório aplicaram uma abordagem abrangente que incluiu revisão da literatura, entrevistas, levantamentos e um estudo Delphi desenvolvido pela equipe técnica do Departamento de Doenças Não Transmissíveis e Saúde Mental da OPAS e pelo grupo de trabalho da GICC para a ALC. Desde 2017, houve um aumento significativo no número de países que passaram a incluir o câncer infantil em regulamentações nacionais. Atualmente, 21 países da América Latina e do Caribe estão envolvidos na implementação da GICC, bem como em atividades e diálogos relacionados. No entanto, os objetivos para 2030 só serão alcançados se os Estados Membros superarem as barreiras ao aceleramento do ritmo de implementação da iniciativa. Existe uma necessidade urgente de intensificar os esforços de controle do câncer infantil na ALC, especialmente no tocante à priorização da detecção em tempo hábil, diagnósticos essenciais, acesso a tratamentos oncológicos, cuidados paliativos e acompanhamento cuidadoso de crianças e adolescentes com câncer.

Regional collaboration for the development of national childhood cancer plans in Latin America and the Caribbean / Colaboración regional para la formulación de planes nacionales contra el cáncer infantil en América Latina y el Caribe / Colaboração regional para o desenvolvimento de planos nacionais de combate ao câncer infantil na América Latina e no Caribe

ABSTRACT This article aims to describe the activities conducted by the National Childhood Cancer Plan Working Group to support the development of national childhood cancer plans in Latin America and the Caribbean in the period 2019-2022, and to present the stage of plan development. The Working Group activities were supported by the Pan American Health Organization and St. Jude Children's Research Hospital, which is the World Health Organization (WHO) Collaborating Centre for Childhood Cancer. Year after year, the workshops and activities developed with the Working Group mobilized key stakeholders: pediatric oncologists, representatives of the Ministry of Health, foundations supporting childhood cancer initiatives, and hospital administrators. As of February 2023, one regional framework is in place, approved by the Council of Ministries of Health of Central America and the Dominican Republic, nine countries are currently implementing national plans or laws that include childhood cancer, and ten countries are writing new plans. The WHO three-step framework helped to guide the Working Group activities. All plans were supported by a situational analysis, which highlighted the importance of having systematized data for evidence-based policies. To increase implementation success, an accompanying budget and timeline help to ensure the adequate implementation of the interventions. More than anything, committed stakeholders remain the most fundamental element to successfully write and approve a national childhood cancer plan. This is an opportunity to share these countries' experience so the strategy can be adapted to support other countries developing a childhood cancer plan and extended to other public health areas.

RESUMEN En este artículo se describen las actividades realizadas por el grupo de trabajo del plan nacional contra el cáncer infantil dirigidas a brindar apoyo para la formulación de planes nacionales contra el cáncer infantil en América Latina y el Caribe en el período 2019-2022, así como la presentación de la etapa de formulación de los planes. Las actividades del Grupo de Trabajo contaron con el apoyo de la Organización Panamericana de la Salud y el St. Jude Children's Research Hospital, que es el centro colaborador de la Organización Mundial de la Salud (OMS) contra el cáncer infantil. Año tras año, los talleres y actividades llevados a cabo con el grupo de trabajo han logrado convocar a las principales partes interesadas: especialistas en oncología pediátrica, representantes del Ministerio de Salud, fundaciones que apoyan iniciativas contra el cáncer infantil y gerentes de los hospitales. Desde febrero del 2023, existe un marco regional, aprobado por el Consejo de Ministerios de Salud de Centroamérica y República Dominicana; nueve países ya están aplicando planes o leyes nacionales en los que se incluye el cáncer infantil, y diez países están redactando nuevos planes. Para orientar las actividades del Grupo de Trabajo, se recurrió al marco en tres pasos de la OMS. Todos los planes se sustentaron en un análisis de situación lo que subraya la importancia de contar con datos sistematizados para que las políticas puedan estar basadas en evidencias. Asimismo, si se pretende aumentar el éxito de la aplicación, sería conveniente contar con un presupuesto y un cronograma que aseguren la aplicación adecuada de las intervenciones. Las partes interesadas implicadas siguen siendo, ante todo, el componente más trascendente en la redacción y aprobación exitosa de un plan nacional contra el cáncer infantil. Esta es una oportunidad para transmitir la experiencia de estos países, con el fin de que la estrategia pueda adaptarse para brindar apoyo a otros países que estén elaborando un plan contra el cáncer infantil y que puede hacerse extensiva a otros ámbitos de la salud pública.

RESUMO Este artigo visa a descrever as atividades realizadas pelo Grupo de Trabalho para Planos Nacionais de Combate ao Câncer infantil a fim de prestar apoio ao desenvolvimento de planos nacionais de combate ao câncer infantil na América Latina e no Caribe no período de 2019 a 2022 e apresentar a atual fase de desenvolvimento dos planos. As atividades do Grupo de Trabalho receberam apoio da Organização Pan-Americana da Saúde e do St. Jude Children's Research Hospital, o Centro Colaborador em Câncer infantil da Organização Mundial da Saúde (OMS). Ano após ano, as oficinas e atividades desenvolvidas com o Grupo de Trabalho mobilizaram as principais partes interessadas: oncologistas pediátricos, representantes dos ministérios da saúde, fundações que apoiam iniciativas de combate ao câncer infantil e administradores de hospitais. Até fevereiro de 2023, havia uma estrutura regional em vigor aprovada pelo Conselho de Ministros da Saúde da América Central e da República Dominicana, nove países estavam implementando planos ou leis nacionais que incluíam o câncer infantil e dez países estavam elaborando novos planos. A estrutura de três etapas da OMS ajudou a orientar as atividades do Grupo de Trabalho. Todos os planos estavam embasados em uma análise situacional, o que destacou a importância de dispor de dados sistematizados para políticas baseadas em evidências. Para aumentar o sucesso da implementação, um orçamento e um cronograma correspondentes ajudam a garantir a implementação adequada das intervenções. Acima de tudo, o compromisso das partes interessadas continua sendo o elemento mais fundamental para elaborar e aprovar com sucesso um plano nacional de combate ao câncer infantil. Esta é uma oportunidade de compartilhar a experiência desses países para que a estratégia possa ser adaptada a fim de apoiar outros países na elaboração de um plano de combate ao câncer infantil e possa ser estendida a outras áreas de saúde pública.

The effect of vitamin D deficiency on the retinal microvasculature: an observational case-control study / O efeito da deficiência de vitamina D nos microvasos da retina: um estudo caso-controle observacional

ABSTRACT Purpose: To determine the effects of vitamin D deficiency on retinal microvascularity using optical coherence tomography angiography. Methods: This study was designed as an observational case-control study. Ninety-eight eyes of patients with vitamin D deficiency and 96 eyes of healthy participants with serum vitamin D level >30 ng/mL were studied. Macula centered, 6.00 × 6.00 mm scan size images were taken. The vessel densities in the superficial and deep retinal capillary plexus, foveal avascular zone area, and choriocapillaris flow area were measured. Results: The groups were comparable in terms of best-corrected visual acuity, sex, axial length, refractive error, age, and adjusted intraocular pressure. The average vitamin D level was significantly lower in the study group (p=0.021). The whole, parafoveal, and perifoveal vessel densities in the deep capillary plexus were considerably higher in the study group than in the control group (p=0.012, p=0.014, and p=0.023, respectively). The foveal avascular zone area and the choriocapillaris flow area were similar in both groups (p=0.37 and p=0.27, respectively) there was a strong negative correlation between the serum vitamin D level and vessel density in the whole image, parafoveal, and perifoveal regions of the deep capillary plexus in the study group (Spearman's rho=-0.71, p=0.043; Spearman's rho= -0.79, p=0.011; and Spearman's rho = -0.74, p=0.032; respectively). Conclusion: An increase in vessel density might originate from vascular structural changes caused by vitamin D deficiency. The increased vessel density, especially in the deep capillary plexus, can enable early diagnosis of vitamin D-associated vasculopathy.

RESUMO Objetivo: Determinar os efeitos da deficiência de vitamina D nos microvasos da retina usando angiotomografia de coerência óptica. Métodos: Este estudo foi planejado para ser do tipo caso-controle observacional. Foram avaliados 98 olhos de pacientes com deficiência de vitamina D e 96 olhos de participantes saudáveis com nível sérico de vitamina D superior a 30 ng/mL. Foram adquiridas imagens de varredura centralizadas na mácula, com um tamanho de 6,00 × 6,00 mm. Mediram-se a densidade dos vasos nos plexos capilares superficial e profundo da retina, a área da zona avascular foveal e a área do fluxo coriocapilar. Resultados: Os grupos mostraram-se semelhantes em relação à melhor acuidade visual corrigida, ao gênero, ao comprimento axial, ao erro refrativo, à idade e à pressão intraocular ajustada. O nível médio de vitamina D foi significativamente menor no grupo de estudo (p=0,021). As densidades total, parafoveal e perifoveal do plexo capilar profundo foram significativamente maiores no grupo de estudo que no grupo controle (respectivamente, p=0,012, p=0,014 e p=0,023). As áreas da zona avascular foveal e do fluxo coriocapilar foram semelhantes nos dois grupos (respectivamente, p=0,37 e p=0,27). Além disso, houve uma forte correlação negativa do nível sérico de vitamina D com as densidades vasculares medidas em toda a imagem e nas regiões parafoveais e perifoveais do plexo capilar profundo no grupo de estudo (respectivamente, ρ de Spearman = −0,71, p=0,043; ρ de Spearman = −0,79, p=0,011; e ρ de Spearman = −0,74, p=0,032). Conclusão: Pode ocorrer um aumento na densidade vascular da retina devido a alterações estruturais dos vasos causadas pela deficiência de vitamina D. O aumento da densidade vascular, especialmente no plexo capilar profundo, pode ser usado para o diagnóstico precoce da vasculopatia associada à deficiência de vitamina D.
