Physical activity as part of the surveillance, monitoring, and evaluation of Primary Health Care in Brazil: a scoping review / La actividad física en la vigilancia, seguimiento y evaluación de la Atención Primaria en Brasil: revisión del alcance / Atividade física na vigilância, monitoramento e avaliação da Atenção Primária à Saúde do Brasil: uma revisão de escopo: Revisão da atividade física na APS do Brasil

OBJECTIVE: Mapping how physical activity (PA) is considered in Primary Health Care (PHC) is essential for aiding planning and management of policies and programs within the Brazilian Unified Health System (SUS). The aim of this study was to map PA-related measures and indicators that are considered in the surveillance, monitoring and evaluation of services and users from the PHC/SUS. METHOD: This is a scoping review with searches conducted in January 2024 on electronic portals related to PHC/SUS. A "snowball" strategy was used to access government documents/reports and their complementary references. Documents were eligible whether they: 1) were government materials; 2) aimed at health surveillance, monitoring/evaluation of services or users from PHC/SUS, and 3) reported PA-related measures or indicators (the behavior and their psychosocial and/or contextual correlates). The selection and extraction process were performed in pairs. A thematic synthesis (evidence map) was applied. RESULTS: Of the 239 potentially eligible documents, 95 were included and summarized according to four groups: health surveillance (n=39), indicators of health plans/policies (n=7), monitoring/evaluation of users (n=34) and services (n =15) from PHC/SUS. A total of 69 measures and 38 different indicators were addressed in health surveillance. The monitoring/evaluation of services includes general- and specific PA programs in PHC/SUS (17 and 13 indicators, respectively). User monitoring/evaluation included indicators aimed at people from different groups (e.g., people with chronic diseases) and their application, primarily in initial examinations and therapeutic planning. CONCLUSIONS: These findings reinforce a call for government actions aiming to qualify the acquisition and implementation of PA-related health information; this may be one the main pathways of strengthening PA promotion on the SUS agenda.

OBJETIVO: Compreender como a atividade física (AF) é contemplada em vigilância, monitoramento e avaliação de serviços e de usuários da Atenção Primária à Saúde (APS) é necessário para auxiliar nas decisões de planejamento e gestão do Sistema Único de Saúde (SUS). O objetivo deste estudo é mapear medidas e indicadores relacionados à AF que são considerados nas estratégias de vigilância, monitoramento e avaliação de serviços e usuários da APS/SUS. MÉTODO: Revisão de escopo com buscas realizadas em janeiro de 2024 em portais eletrônicos relacionados à APS/SUS, usando a estratégia de "bola de neve" e a leitura das referências complementares. Documentos foram elegíveis quando representavam materiais governamentais que eram direcionados para vigilância em saúde, monitoramento/avaliação de serviços e monitoramento/avaliação de usuários na APS/SUS e que continham medidas ou indicadores relacionados à AF (o comportamento em si, global ou por domínios, e seus correlatos psicossociais e/ou contextuais). O processo de seleção e extração foi realizado por pares e uma síntese com representações temáticas das evidências foi realizada. RESULTADOS: Dos 239 documentos potencialmente elegíveis, 95 foram incluídos, abordando vigilância em saúde (n=39), indicadores de planos/políticas de saúde (n=7), monitoramento/avaliação de usuários (n=34) e de serviços (n=15) da APS/SUS. Um total de 69 medidas e 38 indicadores foram contemplados na vigilância. O monitoramento/avaliação de serviços contemplou programas gerais e específicos da AF na APS/SUS (17 e 13 indicadores, respectivamente). O monitoramento/avaliação de usuários incluiu indicadores voltados aos diferentes grupos populacionais (ex., pessoas com doenças crônicas) e sua aplicação, principalmente, em exames iniciais e planejamento terapêutico. CONCLUSÕES: Estes achados reforçam uma chamada para ações governamentais que qualifiquem a aquisição e a implementação das informações em saúde relacionadas à AF, como forma de fortalecer a AF na agenda do SUS.

Oxacillin-resistant Staphylococcus spp.: Impacts on fatality in a NICU in Brazil - confronting the perfect storm.

OBJECTIVE: Analyse the incidence, risk factors, antimicrobial susceptibility profile, and fatality in neonates infected with oxacillin-resistant Staphylococcus spp. (ORS). METHODS: In this retrospective observational descriptive cohort study, the medical records of neonates admitted to the Neonatal Intensive Care Unit (NICU) from January 2015 to June 2022 were analysed. Participants were monitored daily through the National Healthcare Safety Network. RESULTS: Among the 1610 neonates, 193 (12 %) developed ORS infections, primarily in the bloodstream (96.8 %). The incidence of these infections/patient-days decreased by 51.8 % between 2016 (8.3) and 2022 (4). The median age of affected neonates was 17.5 days (IQR:12-28.7). Pre-emptive prescription of fourth-generation cephalosporins (OR=14.36; P<0.01) emerged as a risk factor in the multivariate analysis. Staphylococcus epidermidis was the most prevalent species (60.1 %), with one isolate showing a "susceptible, increased exposure" profile to vancomycin. Additionally, 2 % of pathogens were extensively drug-resistant (XDR). ORS infections were associated with prolonged hospital stays (from 10 to 46 days) and increased mortality (from 10.2 % to 19.2 %). The median time between infection and the fatal outcome was 15 days (IQR:8-40), and Staphylococcus capitis was the most lethal species (26.7 %). CONCLUSIONS: The high incidence of ORS infections was linked to extended hospitalisation and increased mortality, highlighting the complexity of this situation - a "perfect storm." This underscores the urgency of implementing effective interventions for managing and preventing ORS infections in the NICU.

Improving Hepatocellular Carcinoma Surveillance Outcomes in Patients with Cirrhosis after Hepatitis C Cure: A Modelling Study.

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) presents a significant global health challenge, particularly among individuals with liver cirrhosis, with hepatitis C (HCV) a major cause. In people with HCV-related cirrhosis, an increased risk of HCC remains after cure. HCC surveillance with six monthly ultrasounds has been shown to improve survival. However, adherence to biannual screening is currently suboptimal. This study aimed to evaluate the effect of increased HCC surveillance uptake and improved ultrasound sensitivity on mortality among people with HCV-related cirrhosis post HCV cure. METHODS: This study utilized mathematical modelling to assess HCC progression, surveillance, diagnosis, and treatment among individuals with cirrhosis who had successfully been treated for HCV. The deterministic compartmental model incorporated Barcelona Clinic Liver Cancer (BCLC) stages to simulate disease progression and diagnosis probabilities in 100 people with cirrhosis who had successfully been treated for hepatitis C over 10 years. Four interventions were modelled to assess their potential for improving life expectancy: realistic improvements to surveillance adherence, optimistic improvements to surveillance adherence, diagnosis sensitivity enhancements, and improved treatment efficacy Results: Realistic adherence improvements resulted in 9.8 (95% CI 7.9, 11.6) life years gained per cohort of 100 over a 10-year intervention period; 17.2 (13.9, 20.3) life years were achieved in optimistic adherence improvements. Diagnosis sensitivity improvements led to a 7.0 (3.6, 13.8) year gain in life years, and treatment improvements improved life years by 9.0 (7.5, 10.3) years. CONCLUSIONS: Regular HCC ultrasound surveillance remains crucial to reduce mortality among people with cured hepatitis C and cirrhosis. Our study highlights that even minor enhancements to adherence to ultrasound surveillance can significantly boost life expectancy across populations more effectively than strategies that increase surveillance sensitivity or treatment efficacy.

Artificial intelligence applications in the diagnosis and treatment of bacterial infections.

The diagnosis and treatment of bacterial infections in the medical and public health field in the 21st century remain significantly challenging. Artificial Intelligence (AI) has emerged as a powerful new tool in diagnosing and treating bacterial infections. AI is rapidly revolutionizing epidemiological studies of infectious diseases, providing effective early warning, prevention, and control of outbreaks. Machine learning models provide a highly flexible way to simulate and predict the complex mechanisms of pathogen-host interactions, which is crucial for a comprehensive understanding of the nature of diseases. Machine learning-based pathogen identification technology and antimicrobial drug susceptibility testing break through the limitations of traditional methods, significantly shorten the time from sample collection to the determination of result, and greatly improve the speed and accuracy of laboratory testing. In addition, AI technology application in treating bacterial infections, particularly in the research and development of drugs and vaccines, and the application of innovative therapies such as bacteriophage, provides new strategies for improving therapy and curbing bacterial resistance. Although AI has a broad application prospect in diagnosing and treating bacterial infections, significant challenges remain in data quality and quantity, model interpretability, clinical integration, and patient privacy protection. To overcome these challenges and, realize widespread application in clinical practice, interdisciplinary cooperation, technology innovation, and policy support are essential components of the joint efforts required. In summary, with continuous advancements and in-depth application of AI technology, AI will enable doctors to more effectivelyaddress the challenge of bacterial infection, promoting the development of medical practice toward precision, efficiency, and personalization; optimizing the best nursing and treatment plans for patients; and providing strong support for public health safety.

RIPS (rapid intuitive pathogen surveillance): a tool for surveillance of genome sequence data from foodborne bacterial pathogens.

Monitoring data submitted to the National Center for Biotechnology Information's Pathogen Detection whole-genome sequence database, which includes the foodborne bacterial pathogens Listeria monocytogenes, Salmonella enterica, and Escherichia coli, has proven effective for detecting emerging outbreaks. As part of the submission process, new sequence data are typed using a whole-genome multi-locus sequence typing scheme and clustered with sequences already in the database. Publicly available text files contain the results of these analyses. However, contextualizing and interpreting this information is complex. We present the Rapid Intuitive Pathogen Surveillance (RIPS) tool, which shows the results of the NCBI Rapid Reports, along with appropriate metadata, in a graphical, interactive dashboard. RIPS makes the information in the Rapid Reports useful for real-time surveillance of genome sequence databases.

Cumplimiento de las recomendaciones de la OMS para la notificación de COVID-19 en Argentina

Introducción : La Organización Mundial de la Salud (OMS) efectuó recomendaciones en relación con la recopilación y notificación de datos agregados semanales de COVID-19. Objetivo : Investigar el grado de cumplimiento de las recomendaciones elaboradas por la OMS para la notificación de casos y muertes de COVID-19 en la Argentina durante el año 2020 a 2022, y comparar la notificación de muertes con el número de defunciones por COVID-19 consolidadas en el registro de estadísticas vitales del país. Materiales y métodos : Estudio cuantitativo descriptivo, basado en revisión documental y en fuentes de datos secundarias. Se utilizó los reportes diarios de información epidemiológica y la base de datos Dataset, COVID-19 casos registrados en la República Argentina. Adicionalmente, para estimar la omisión en los registros epidemiológicos de fallecimientos por COVID-19 en los años 2020 y 2021, se cotejaron los resultados de las bases de datos Dataset COVID-19 con la base de las Estadísticas vitales de mortalidad por causa de defunción, proporcionadas por la Dirección de Estadísticas e Información en Salud (DEIS). Se analizaron las variables recomendadas por la OMS para la notificación de casos y muertes por COVID-19. En cuanto a las consideraciones éticas relacionadas con el uso de la información utilizada en este trabajo, las bases de datos cumplen con lo estipulado por la Ley Nacional N° 17.622 de Resguardo del Secreto Estadístico, garantizando que la información mantiene el carácter confidencial y reservado del informante. Resultados: Del análisis de los reportes diarios, durante 2020 se observó que, de los 13 indicadores recomendados, 9 presentan datos algunos meses y los 4 restantes no se relevaron; en 2021 solo 7 indicadores presentaron datos algunos meses, y en 2022 solo 3 indicadores se continuaron informando. Respecto al análisis de la base de datos Dataset COVID-19, la mayoría fueron captadas. Respecto a la comparación de los valores de las defunciones registradas por el sistema de vigilancia epidemiológica y por la DEIS para los años 2020 y 2021, las muertes registradas fueron superiores en el registro de la DEIS (9,6% y 14,2%). Conclusiones : El Estado argentino cumplió con gran parte de las recomendaciones que establece la OMS para la notificación de los casos de COVID-19. Estudios posteriores deberían analizar otros componentes de la calidad de los datos, así como la oportunidad de los registros de defunciones, característica necesaria para la toma de decisiones en salud pública.

Introduction : The World Health Organization (WHO) establishes recommendations regarding the collection and reporting of weekly aggregated data on COVID-19. Objective : To investigate the degree of compliance with the recommendations made by the WHO for the reporting of COVID-19 cases and deaths in Argentina during the years 2020 to 2022, and to compare death notifications with the number of COVID-19 deaths recorded in the country's vital statistics registry. Materials and methods : Descriptive quantitative study, based on a documentary review and secondary data sources. Daily reports of epidemiological information and the Dataset database containing registered COVID-19 cases in the Argentine Republic were used. Additionally, to estimate the omission in the epidemiological records of COVID-19 deaths in the years 2020 and 2021, the results of the Dataset COVID-19 databases were compared with the vital statistics death registry on cause of death, provided by the Directorate of Statistics and Health Information (DEIS, by its acronym in Spanish). The variables recommended by the WHO for the reporting of COVID-19 cases and deaths were analyzed. As for the ethical considerations related to the use of the information in this study, the databases comply with the provisions of National Law 17,622 on the Protection of Statistical Secrecy, ensuring that the information remains confidential and reserved for the informant. Results : From the analysis of daily reports, it was observed that in 2020, out of the 13 recommended indicators, 9 had data for some months, and the remaining 4 were not reported. In 2021 only 7 indicators had data for some months, and in 2022 only 3 indicators continued to be reported. Regarding the analysis of the Dataset COVID-19 database, most data were captured. In comparing the values of deaths recorded by the epidemiological surveillance system and by the DEIS for the years 2020 and 2021, the deaths recorded were higher in the DEIS registry (9.6% and 14.2%). Conclusions : The Argentine state largely complied with the recommendations established by the WHO for the reporting of COVID-19 cases. Subsequent studies should analyze other components of data quality, as well as the timeliness of death records, a necessary characteristic for public health decision-making.

Congenital anomalies during Covid-19: artifact of surveillance or a real TORCH?

Infections in the first trimester of pregnancy can be teratogenic, but the possibility that Covid-19 could lead to birth defects is unclear. We examined whether SARS-CoV-2 infection during pregnancy or exposure to pandemic conditions were associated with the risk of congenital anomalies. We carried out a retrospective study of 420,222 neonates born in Quebec, Canada in two time periods: prepandemic (January 1, 2017 to March 12, 2020) vs. pandemic (March 13, 2020 to March 31, 2022). We classified pandemic births as early (first trimester completed before the pandemic) or late (first trimester during the pandemic), and identified patients with SARS-CoV-2 infections during pregnancy. We applied (1) adjusted log-binomial regression models to assess the association between SARS-CoV-2 infection and congenital anomalies, and (2) autoregressive interrupted time series regression to analyze temporal trends in the monthly number of defects in all patients regardless of infection. In total, 29,263 newborns (7.0%) had a congenital anomaly. First trimester SARS-CoV-2 infections were not associated with a greater risk of birth defects compared with no infection (RR 1.07, 95% CI 0.59-1.95). However, births during the late pandemic period were more likely to be diagnosed with congenital microcephaly compared with prepandemic births (RR 1.44, 95% CI 1.21-1.71). Interrupted time series analysis confirmed that the frequency of microcephaly increased during the late pandemic period, whereas other anomalies did not. We conclude that Covid-19 is likely not teratogenic, but enhanced surveillance of anomalies among late pandemic births may have heightened the detection of infants with microcephaly.

Machine learning in predicting severe acute respiratory infection outbreaks / Aprendizado de máquina na previsão de surtos de síndrome respiratória aguda grave / Aprendizaje automático en la predicción de brotes de síndrome respiratorio agudo grave

Abstract: Severe acute respiratory infection (SARI) outbreaks occur annually, with seasonal peaks varying among geographic regions. Case notification is important to prepare healthcare networks for patient attendance and hospitalization. Thus, health managers need adequate resource planning tools for SARI seasons. This study aims to predict SARI outbreaks based on models generated with machine learning using SARI hospitalization notification data. In this study, data from the reporting of SARI hospitalization cases in Brazil from 2013 to 2020 were used, excluding SARI cases caused by COVID-19. These data were prepared to feed a neural network configured to generate predictive models for time series. The neural network was implemented with a pipeline tool. Models were generated for the five Brazilian regions and validated for different years of SARI outbreaks. By using neural networks, it was possible to generate predictive models for SARI peaks, volume of cases per season, and for the beginning of the pre-epidemic period, with good weekly incidence correlation (R2 = 0.97; 95%CI: 0.95-0.98, for the 2019 season in the Southeastern Brazil). The predictive models achieved a good prediction of the volume of reported cases of SARI; accordingly, 9,936 cases were observed in 2019 in Southern Brazil, and the prediction made by the models showed a median of 9,405 (95%CI: 9,105-9,738). The identification of the period of occurrence of a SARI outbreak is possible using predictive models generated with neural networks and algorithms that employ time series.

Resumo: Surtos de síndrome respiratória aguda grave (SRAG) ocorrem anualmente, com picos sazonais variando entre regiões geográficas. A notificação dos casos é importante para preparar as redes de atenção à saúde para o atendimento e internação dos pacientes. Portanto, os gestores de saúde precisam ter ferramentas adequadas de planejamento de recursos para as temporadas de SRAG. Este estudo tem como objetivo prever surtos de SRAG com base em modelos gerados com aprendizado de máquina usando dados de internação por SRAG. Foram incluídos dados sobre casos de hospitalização por SRAG no Brasil de 2013 a 2020, excluindo os casos causados pela COVID-19. Estes dados foram preparados para alimentar uma rede neural configurada para gerar modelos preditivos para séries temporais. A rede neural foi implementada com uma ferramenta de pipeline. Os modelos foram gerados para as cinco regiões brasileiras e validados para diferentes anos de surtos de SRAG. Com o uso de redes neurais, foi possível gerar modelos preditivos para picos de SRAG, volume de casos por temporada e para o início do período pré-epidêmico, com boa correlação de incidência semanal (R2 = 0,97; IC95%: 0,95-0,98, para a temporada de 2019 na Região Sudeste). Os modelos preditivos obtiveram uma boa previsão do volume de casos notificados de SRAG; dessa forma, foram observados 9.936 casos em 2019 na Região Sul, e a previsão feita pelos modelos mostrou uma mediana de 9.405 (IC95%: 9.105-9.738). A identificação do período de ocorrência de um surto de SRAG é possível por meio de modelos preditivos gerados com o uso de redes neurais e algoritmos que aplicam séries temporais.

ABSTRACT Objective: To describe the process of implementing a cancer surveillance technical group based on the health advocacy framework. Method: Convergent Care Research addressing 11 representatives of the support and governance system of the healthcare network in a town in Santa Catarina, Brazil. Data were collected from June 2020 to July 2021 in online meetings called convergence groups. The analysis followed the apprehension, synthesis, theorization, and transference steps. Results: The motivations for creating the group included the town's cancer epidemiological context, the need to meet the annual health program, and the professionals' duties in this context. Based on the advocacy framework, the group associated the implementation process with concepts such as integrality, humanization, and professional practice in health. Along this path, strategies were acknowledged and supported the group, such as the establishment and appropriation of philosophical and theoretical bases, in addition to actions such as creating a statute, planning activities, developing instruments, and identifying priorities to implement tasks effectively. Conclusion: Knowledge was exchanged, and a process for providing integral and equitable healthcare in cancer surveillance was developed collectively. Hence, advocacy proved to be a theoretical pillar for the political action of the technical group's members, translating practice into patient rights advocacy.

Nueve años de tendencia en la resistencia a ciprofloxacina por Escherichia coli: estudio transversal en un hospital de Colombia / Nine-year trend in Escherichia coli resistance to ciprofloxacin: cross-sectional study in a hospital in Colombia / Tendência de nove anos na resistência da Escherichia coli à ciprofloxacina: um estudo transversal em um hospital na Colômbia

Resumen: La ciprofloxacina es un antibiótico de importancia crítica para la salud humana. El aumento de la resistencia de Escherichia coli a ciprofloxacina es un problema de salud pública global por su importancia en el tratamiento de infecciones urinarias complicadas y otras infecciones graves; sin embargo, su prescripción es alta en el caribe colombiano. El objetivo fue determinar la tendencia de resistencia de E. coli a ciprofloxacina en un hospital colombiano de alta complejidad. A partir de reportes de antibiogramas, los aislados fueron categorizados según los criterios del Instituto de Normas Clínicas y de Laboratorio de los Estados Unidos para cada año estudiado; se calcularon proporciones y se exploraron diferencias en la sensibilidad con pruebas χ2. Se utilizó la prueba de Cochran-Armitage para evaluar la tendencia de la resistencia. Valores de p ≤ 0,05 se consideraron significativos. Se analizaron 6.848 aislados, encontrándose una resistencia de 49,31%. Según el origen, la resistencia más alta fue en muestras comunitarias (51,96% - IC95%: 50,51; 53,41), y por tipo de muestra, en piel y tejidos (61,76% - IC95%: 56,96; 66,35) y orina (48,97% - IC95%: 47,71; 50,23). Se halló una tendencia al aumento en la resistencia por año (p < 0,0001), en muestras comunitarias (p = 0,0002) y en orina (p < 0,0001). La resistencia a ciprofloxacina es alta y tiende al aumento en comunidad y en orina, superando el límite establecido para su uso a nivel ambulatorio, lo que es preocupante por la alta prescripción de fluoroquinolonas en la localidad.

Abstract: Ciprofloxacin is a critically important antibiotic for human health. The increase of Escherichia coli resistance to ciprofloxacin is a global public health problem due to its importance in the treatment of complicated urinary tract infections and other serious infections; however, its prescription is high in the Colombian Caribbean. The objective was to determine the resistance trend of E. coli to ciprofloxacin in a Colombian hospital of high complexity. From antibiogram reports, isolates were categorized according to Clinical and Laboratory Standards Institute criteria for each year studied; proportions were calculated and differences in sensitivity were explored using the χ2 test. The Cochran-Armitage test was used to evaluate the resistance trend. Significance was considered when p-value ≤ 0.05. In total, 6,848 isolates were analyzed, and 49.31% resistance was found. According to origin, the highest resistance was in community samples (51.96% - 95%CI: 50.51; 53.41), and by type of sample, in skin and tissues (61.76% - 95%CI: 56.96; 66.35) and urine (48.97% - 95%CI: 47.71; 50.23). Increasing trends were observed for resistance per year (p < 0.0001), community samples (p = 0.0002) and urine (p < 0.0001). Resistance to ciprofloxacin is high and tends to increase in the community and in urine, exceeding the limit established for its use at the ambulatory level, which is of concern due to the high prescription of fluoroquinolones in the locality.

Resumo: A ciprofloxacina é um antibiótico extremamente importante para a saúde humana. O aumento da resistência da Escherichia coli à ciprofloxacina é um problema de saúde pública global devido à sua importância no tratamento de infecções complicadas do trato urinário e outras infecções graves; no entanto, sua prescrição é alta no caribe colombiano. O objetivo foi determinar a tendência de resistência da E. coli à ciprofloxacina em um hospital colombiano de alta complexidade. A partir de relatórios de antibiogramas, os isolados foram categorizados de acordo com os critérios do Instituto de Padrões Clínicos e Laboratoriais dos Estados Unidos para cada ano estudado; as proporções foram calculadas e as diferenças de sensibilidade foram exploradas com os testes χ2. O teste de Cochran-Armitage foi usado para avaliar a tendência de resistência. Os valores de p ≤ 0,05 foram considerados significativos. Um total de 6.848 isolados foi testado e foi encontrada uma taxa de resistência de 49,31%. Por origem, a resistência foi mais alta em amostras comunitárias (51,96% - IC95%: 50,51; 53,41) e, por tipo de amostra, em pele e tecidos (61,76% - IC95%: 56,96; 66,35) e urina (48,97% - IC95%: 47,71; 50,23). Foi encontrada uma tendência de aumento na resistência por ano (p < 0,0001), em amostras da comunidade (p = 0,0002) e na urina (p < 0,0001). A resistência à ciprofloxacina é alta e tende a aumentar na comunidade e na urina, excedendo o limite estabelecido para uso ambulatorial, o que é preocupante, dada a alta prescrição de fluoroquinolonas na localidade.

Retos del Sistema Nacional de Salud en los tiempos pos-COVID / Challenges of the National Health System in post-COVID times

El Sistema Nacional de Salud de Cuba se fundó en el año 1961 y es una entidad dependiente del Ministerio de Salud Pública de Cuba. Este constituye una prioridad nacional, tiene carácter universal, gratuito y se basa en el modelo del médico de familia, con un enfoque clínico, epidemiológico y social de los problemas sanitarios. Se sustenta en siete principios que expresan el derecho del pueblo a la salud, con responsabilidad del Estado, y las prácticas de salud se sostienen sobre una base científica sólida con acciones preventivas. En el año 2019, una epidemia azotó a la mayoría de los países del mundo (la COVID-19), entre ellos, Cuba. Ello conllevó a que los profesionales de la salud asumieran retos importantes ante una situación de salud sin precedentes. Este trabajo se refiere a los retos asumidos, principalmente, después de la COVID-19.

The Cuban National Health System was founded in 1961 and is an entity dependent on the Cuban Ministry of Public Health. This constitutes a national priority, is universal, free and is based on the family doctor model, with a clinical, epidemiological and social approach to health problems. It is supported in seven principles that express the right of the people to health, with responsibility of the State and the health practices are sustained on a solid scientific basis with preventive actions. In 2019, an epidemic hit most of the countries in the world (COVID-19), including Cuba. This led health professionals to assume important challenges in order to face an unprecedented health situation. This work refers to the challenges assumed, mainly, after COVID-19.

Sporadic Shiga Toxin-Producing Escherichia coli-Associated Pediatric Hemolytic Uremic Syndrome, France, 2012-2021.

Shiga toxin-producing Escherichia coli-associated pediatric hemolytic uremic syndrome (STEC-HUS) remains an important public health risk in France. Cases are primarily sporadic, and geographic heterogeneity has been observed in crude incidence rates. We conducted a retrospective study of 1,255 sporadic pediatric STEC-HUS cases reported during 2012-2021 to describe spatiotemporal dynamics and geographic patterns of higher STEC-HUS risk. Annual case notifications ranged from 109 to 163. Most cases (n = 780 [62%]) were in children <3 years of age. STEC serogroups O26, O80, and O157 accounted for 78% (559/717) of cases with serogroup data. We identified 13 significant space-time clusters and 3 major geographic zones of interest; areas of southeastern France were included in >5 annual space-time clusters. The results of this study have numerous implications for outbreak detection and investigation and research perspectives to improve knowledge of environmental risk factors associated with geographic disparities in STEC-HUS in France.

Waning protection after vaccination and prior infection against COVID-19-related mortality over 18 months.

OBJECTIVES: Evidence on waning patterns in protection from vaccine-induced, infection-induced, and hybrid immunity against death is scarce. The aim of this study is to assess the temporal trends in protection against mortality. METHODS: Population-based case-control study nested in the total population of Scania Region, Sweden using individual-level registry data of COVID-19-related deaths (<30 days after positive SARS-CoV-2 test) between 27 December 2020 and 3 June 2022. Controls were matched for age, sex, and index date. Conditional logistic regression was used to estimate the preventable fraction (PF) from vaccination (PFvac corresponding to vaccine effectiveness; ≥2 vaccine doses vs. 0 doses), prior infection (PFinf), and hybrid immunity (PFhybrid). PF was calculated as one minus odds ratio. Models were adjusted for comorbidities, long-term care facility residence, prior infection (for PFvac), country of birth, socio-economic conditions, and time since last vaccination (for PFinf). RESULTS: In total, 14 936 individuals (1440 COVID-19-related deaths and 13 496 controls) were included in the case-control analyses (45% females, median age: 84 years). PFvac was above 90% during the first month after vaccination, regardless of the number of vaccine doses. After 6 months, PFvac of two doses waned to 34% (95% CI: -30% to 66%). PFinf for people surviving a SARS-CoV-2 infection waned from 88% (-16% to 99%) 3 months after infection to 62% (34-79%) after 9 months. No differences in waning patterns in PFvac were seen between virus variants, gender, and age. DISCUSSION: Given the waning of protection against death, continuous surveillance of population immunity status, particularly among the most vulnerable population groups, could help to further fine-tune vaccination recommendations.

Epidemiologic transition of lung cancer mortality in Italy by sex, province of residence and birth cohort (1920-1929 to 1960-1969).

Space-time analysis of mortality risk is useful to evaluate the epidemiologic transitions at the subnational level. In our study, we analysed the death certificate records for lung cancer in Italy in 1995-2016, obtained from the Italian National Institute of Statistics. Our objective was to investigate the spatial-temporal evolution of lung cancer mortality by sex and province of residence (n = 107) using the birth cohort as relevant time axis. We built Bayesian space-time models with space-time interactions. Among males (n = 554 829), mortality peaked in the 1920-1929 cohort, followed by a generalised decline. Among females (n = 158 619), we found novel original evidence for a peak in the 1955-1964 cohort, equivalent to a 35-year delay, with a downward trend being observed thereafter. Over time, the documented north-south decreasing mortality gradient has been replaced by a west-east decreasing gradient. Naples has become the province at highest risk in Italy, both among males and females. This pattern is consistent with an epidemiologic transition of risk factors for lung cancer to the south-west of the country and raises concern, because 5-year age-standardised net survival from the disease in this geographic area is lower than in northern and central Italy. The variability of mortality rates among provinces has changed over time, with an increasing homogeneity for males and an opposite trend for females in the more recent birth cohorts. These unprecedented observations provide evidence for a profound spatio-temporal transition of lung cancer mortality in Italy.

Hantavirus in Panama: Twenty Years of Epidemiological Surveillance Experience.

Twenty years have passed since the emergence of hantavirus zoonosis in Panama at the beginning of this millennium. We provide an overview of epidemiological surveillance of hantavirus disease (hantavirus pulmonary syndrome and hantavirus fever) during the period 1999-2019 by including all reported and confirmed cases according to the case definition established by the health authority. Our findings reveal that hantavirus disease is a low-frequency disease, affecting primarily young people, with a relatively low case-fatality rate compared to other hantaviruses in the Americas (e.g., ANDV and SNV). It presents an annual variation with peaks every 4-5 years and an interannual variation influenced by agricultural activities. Hantavirus disease is endemic in about 27% of Panama, which corresponds to agroecological conditions that favor the population dynamics of the rodent host, Oligoryzomys costaricensis and the virus (Choclo orthohantavirus) responsible for hantavirus disease. However, this does not rule out the existence of other endemic areas to be characterized. Undoubtedly, decentralization of the laboratory test and dissemination of evidence-based surveillance guidelines and regulations have standardized and improved diagnosis, notification at the level of the primary care system, and management in intensive care units nationwide.

Epidemiological Surveillance Reveals the Rise and Establishment of the Omicron SARS-CoV-2 Variant in Brazil.

The introduction of SARS-CoV-2 variants of concern (VOCs) in Brazil has been associated with major impacts on the epidemiological and public health scenario. In this study, 291,571 samples were investigated for SARS-CoV-2 variants from August 2021 to March 2022 (the highest peak of positive cases) in four geographical regions of Brazil. To identify the frequency, introduction, and dispersion of SARS-CoV-2 variants in 12 Brazilian capitals, VOCs defining spike mutations were identified in 35,735 samples through genotyping and viral genome sequencing. Omicron VOC was detected in late November 2021 and replaced the Delta VOC in approximately 3.5 weeks. We estimated viral load differences between SARS-CoV-2 Delta and Omicron through the evaluation of the RT-qPCR cycle threshold (Ct) score in 77,262 samples. The analysis demonstrated that the Omicron VOC has a lower viral load in infected patients than the Delta VOC. Analyses of clinical outcomes in 17,586 patients across the country indicated that individuals infected with Omicron were less likely to need ventilatory support. The results of our study reinforce the importance of surveillance programs at the national level and showed the introduction and faster dispersion of Omicron over Delta VOC in Brazil without increasing the numbers of severe cases of COVID-19.

Sobre la hepatitis aguda grave de etiología desconocida: la situación en México / About severe acute hepatitis of unknown etiology: the situation in Mexico

Introducción: en México, las hepatitis virales son de notificación epidemiológica obligatoria, pero no existe un sistema especial de vigilancia. La información disponible se limita a la distribución por edad y sexo. Ante la alerta de casos de hepatitis aguda grave de etiología desconocida, en la Unión Europea el Consejo Nacional de Vigilancia Epidemiológica (CONAVE) alertó al Sistema Nacional de Salud (SNS) para la atención y vigilancia de estos casos. Desarrollo: la hipótesis más convincente sobre la etiología está relacionada con una respuesta inmunitaria exacerbada que es mediada por superantígenos relacionados con la proteína espiga del SARS-CoV-2, activados por una infección por adenovirus que desencadena una respuesta de linfocitos T que provoca apoptosis de hepatocitos. Con base en la presentación clínica (niños menores de 16 años, con diarrea, dolor abdominal, ictericia, vómito e hipertransaminasemia) se han diseñado definiciones operacionales para su identificación y notificación al Sistema Nacional de Vigilancia Epidemiológica (SINAVE). Hasta junio del 2022, se han identificado 56 casos en México. Conclusiones: este brote de hepatitis representa un reto para el SINAVE. Es necesario incluir la identificación de adenovirus en el algoritmo diagnóstico de enfermedad respiratoria viral, implementar un sistema especial de vigilancia epidemiológica de hepatitis virales y sensibilizar a los profesionales sanitarios en el tema.

Introduction: In Mexico viral hepatitis requires mandatory epidemiological notification, but there is no special surveillance system. Available information is limited to distribution of cases by age and sex. Given the alert of cases of severe acute hepatitis of unknown etiology in the European Union, the National Council for Epidemiological Surveillance (Consejo Nacional de Vigilancia Epidemiológica) alerted the entire National Health System to care for and monitor these cases in Mexico. Development: The most convincing hypothesis is an exacerbated immune response mediated by superantigens related to the spike protein of SARS-CoV-2, activated by adenovirus infection that ends in a response of T lymphocytes that causes apoptosis of hepatocytes. Based on clinical presentation (children under 16 years of age, with diarrhoea, abdominal pain, jaundice, vomiting and increase in transaminases) the operational case definitions have been designed for their timely identification and notification to the National System of Epidemiological Surveillance (Sistema Nacional de Vigilancia Epidemiológica). Until June 2022, 56 cases have been identified in Mexico. Conclusions: This hepatitis outbreak represents a challenge for the National System of Epidemiological Surveillance. It is necessary to include the identification of adenovirus in the diagnostic algorithm for viral respiratory disease, to implement a special epidemiological surveillance system for viral hepatitis, and to sensitize health professionals on this subject.
