Pragmatic Carbohydrate Quality Metrics in Relation to Glycemic Index, Glycemic Load, and Front-of-Pack Warning Labels in Grain Foods

The challenges in the characterization of the nutritional quality of grain foods comprise obstacles to public health actions toward promotion of healthier grain-based foods. The present study investigated how carbohydrate metrics related to glycemic index (GI), glycemic load (GL), and warning labels of grain foods consumed by individuals living in São Paulo, Brazil. Information on intake of grain foods at individual level was obtained using 24 h recalls within a cross-sectional population-based survey conducted in 2015. There were 244 unique grain products reported by individuals in the survey, assessed through four metrics of carbohydrate quality, considering contents per 10 g of total carbohydrate: (1) ≥1 g fiber, (2) ≥1 g fiber and <1 g free sugars, (3) ≥1 g fiber and <2 g free sugars, and (4) ≥1 g fiber, and <2 g free sugars per 1 g of fiber. Outcomes included GI, GL, and inclusion of warning labels proposed by the Brazilian National Health Surveillance Agency (ANVISA), the Chilean Ministry of Health (1st and 3rd stages), and the Pan American Health Organization (PAHO). Metrics identified products with lower mean GI (−12.8 to −9.0 [p-values < 0.001]), and GL (−12.5 to −10.3 [p-values < 0.001]). Warning systems showed a certain degree of discrimination between products according to the metrics (p-value < 0.01 each); however, >50% of products with good nutritional quality according to the carbohydrate metrics still would receive warnings. Findings suggest that carbohydrate metrics identified products with lower GI and GL, and current warning labels may not adequately capture overall nutritional quality of grain foods.

Building Capacity and Advancing Regulatory Measures to Improve Food Environments in the Region of the Americas.

Noncommunicable diseases (NCDs) are the main cause of death globally (70%) and in the Region of the Americas (80%), and poor diets are a leading driver of NCDs. In response, the Pan American Health Organization (PAHO)/World Health Organization (WHO) introduced a set of evidence-based regulatory measures to help countries improve diets through the reduced consumption of processed and ultra-processed foods. This paper aims to describe the needs of and propose actions for key actors to advance these measures. A workshop was designed to assess member states' regulatory capacity. A thematic analysis was conducted to analyze regional needs, successes and challenges. Thereafter, the Government Capacity-Building Framework for the prevention and control of NCDs was used to examine findings. The findings were organized in two sets: (i) PAHO/WHO actions to support member states and (ii) key actors' actions to advance regulatory policies. The results show notable regulatory progress across the Region of the Americas. However, progress differs between countries, with opportunities to strengthen measures in most countries, mainly in conflict of interest management. The results identified important actions to strengthen the regulatory capacity of PAHO/WHO member states. To maximize momentum for these actions, timelines must be identified, and political commitment can be boosted by applying human rights-based and food system-wide approaches.

Biovigilance systems: Cells, tissues, and organs donation and transplantation

Objective: to describe Biovigilance Systems and their associated management tools among member countries of the World Health Organization. Method: overview conducted following the population, concept, and context strategy to develop the research question and objective. Structured searches were conducted in PubMed, CINAHL, Embase, and Scopus. Snowballing procedure in Google Scholar and health authorities’ websites as World Health Organization and Pan American Health Organization during the first semester of 2023. Language and time restrictions were not applied. Results: we examined more than 70 studies and non-scientific works. Biovigilance systems were identified in 12 countries members of WHO in 3 of 6 regions: Pan-American Region (Brazil and Colombia, Canada), Europe (England, France, Germany, Italy, Netherlands, Poland, Portugal, and Spain), and Western Pacific Region (Australia). Conclusion: This overview achieved its objective by describing biovigilance systems and their management tools among World Health Organization member countries. This research, designed as an overview, refrains from generalizing results but holds significance for countries and health authorities developing biovigilance systems, offering benchmark opportunities and supporting system improvement. The study contributes directly to the biovigilance discourse, guiding efforts to enhance safety and quality globally.

Childhood and adolescent cancer in Chile: examining challenges and shaping tomorrow.

The aim of this study was to describe the epidemiology of childhood cancer in Chile and the disease landscape, assessing achievements, collaborations, and future challenges to be addressed by the National Plan for Child and Adolescent Cancer Control. This descriptive study provides a general overview of national and international collaboration strategies and discusses the results of the Third Childhood Cancer Surveillance Report (2017-2019), the St. Jude Pediatric Oncology Facility Integrated Local Evaluation Tool (or PrOFILE) report, collaboration with the Pan American Health Organization within the framework of the Global Initiative for Childhood Cancer and the development of the National Plan for Child and Adolescent Cancer Control within the CureAll framework. The analysis reveals the impact of childhood cancer by considering the incidence between 2017 and 2019, encompassing gender disparities. Leukemia is the most frequently occurring type of cancer, accounting for 40.4% of cancers among children and adolescents younger than 15 years and with an incidence of 57.5 cases per 1 million children in this age group. Cancer is the second leading cause of death among those aged 5-14 years. Cancer survival increased between 2007 and 2019, with 78.4% survival at 5 years post-diagnosis in 2023. The development of the National Plan for Child and Adolescent Cancer Control involved assessing the situation, setting goals and devising an action plan to reduce mortality from cancer in childhood and increase survival rates through early interventions and smooth transitions to adult care. Chile has made progress in childhood cancer indicators, particularly in increasing survival, demonstrating its commitment to improving care for children with cancer, and this has been achieved through legislative frameworks, national planning, collaborative partnerships and participation in global initiatives. Despite the progress made, ongoing research, strong policy implementation and multidisciplinary collaborations remain vital to addressing persistent challenges. This study highlights the need to refine health systems, data collection methodologies and global cooperation to ensure optimal care for every child facing cancer, thus improving their chances of survival and their overall quality of life.

Maintaining the Region of the Americas free of polio: best practices for incident management support teams.

The Pan American Health Organization (PAHO) and its Member States have been leading the efforts to eradicate wild poliovirus in the Region of Americas since smallpox's successful elimination in 1971. The region became the first to be certified free of wild poliovirus in 1994. However, in July 2022, an unvaccinated patient with no recent travel history was diagnosed with poliomyelitis in the United States of America. In response to the emergence of a circulating vaccine-derived poliovirus in the United States, PAHO established the Polio Incident Management Support Team. This team has been coordinating response efforts, focusing on: coordination, planning, and monitoring; risk communication and community engagement; surveillance and case investigation; vaccination; and rapid response. In this paper, we identified and documented best practices observed following establishment of the Incident Management Support Team (September 2022-2023) through a comprehensive review and analysis of various data sources and country-specific data from the polio surveillance dashboard. The aim was to share these best practices, highlighting technical support and implementation of polio measures by Member States. Despite several challenges, the Americas region remains polio-free. Polio risk is declining, with a July 2023 assessment showing fewer countries at medium, high, and very high risk. This progress reflects improved immunization coverage, surveillance, containment, health determinants, and outbreak preparedness and response. The PAHO Polio Incident Management Support Team has played a key role in supporting these efforts.

Seroprevalence of Trypanosoma cruzi among children from Veracruz, Mexico: Epidemiological baseline for a control model based on Chagas disease active transmission

Introduction. In 2021, the Secretaría de Salud de México and the Pan American Health Organization launched an initiative to interrupt intra-domiciliary vector transmission of Trypanosoma cruzi based on the prevalence of Chagas disease in children. The Mexican State of Veracruz was leading this initiative. Objective. To estimate the seroprevalence of T. cruzi infection among children under 15 years of age from rural areas of Veracruz, México. Materials and methods. We identified eight localities of high priority from the Municipality of Tempoal, Veracruz, for baseline serology. Blood samples were collected on filter paper from 817 individuals between June and August 2017, for screening with a third-generation enzyme immunoassay. Reactive cases were confirmed by indirect hemagglutination, enzyme-linked immunosorbent assay, and indirect immunofluorescence tests on peripheral blood serum samples. We calculated seroprevalence and 95% confidence intervals (CI). Results. We confirmed Chagas disease cases in children under 15 years of age with a seroprevalence of 1,9% (95 % CI = 1,12-3,16) in the localities of Citlaltepetl, Cornizuelo, Cruz de Palma and Rancho Nuevo. Conclusions. These results indicate recent transmission of T. cruzi in these communities and allow to establish an epidemiological baseline for the design and implementation of a model focused on geographical areas with active transmission to advance toward the elimination of intra-domiciliary vector transmission of this parasite in Mexico.

[Ranking of immunization programs in Latin America, 2020Ranking dos programas de vacinação na América Latina, 2020].

Construct a ranking of national immunization programs in Latin America in 2020 and compare it with the previous year. Eighteen national immunization programs were evaluated on the basis of public information obtained from official sites of the countries' ministries of health, the World Health Organization, the Pan American Health Organization, the United Nations Children's Fund, and local sources. The ranking was based on the 2020 vaccination schedule for different life stages, special situations, vaccination against influenza, 2019 vaccination coverage, and programmatic aspects. Vaccination coverage decreased in most countries. The average regional declined in 2020, as did the scores for most countries, except Chile and Colombia. Chile leads the ranking, followed by Uruguay, Panama, and Costa Rica. Chile stands out for its full calendar, higher vaccination coverage rates, and programmatic achievements. The lower overall score in 2020 highlights the need to recover the Region's vaccination coverage rates. This analysis seeks to motivate countries to address pending challenges.

Haiti resurging epidemics: Its potential to transition to endemic status

The island nation of Haiti had been Cholera free for over a century prior to the 2010 earthquake which left over 1 million inhabitants homeless, when a key community water source became inadvertently contaminated with the causative organism, V. cholerae (El Toro strain 01) soon after the earthquake. The infectious organism was apparently transmitted via well intentioned Nepalese aid workers visiting the Island. During the 2010-2018 outbreak, over 819,000 people were treated for cholera, resulting in nearly 10,000 deaths. With assistance from the CDC, the U.S. Agency for International Development, and implementing partners including the Pan American Health Organization to further expand epidemiologic and public health initiatives, Haiti was once again declared cholera free in February 2022, having no new cases for over 3 years; however, by Sept 2022 new cases were once again reported, ultimately affecting over 20,000 additional mostly Haitian residents, geographically centered around the Port au Prince area, and in 285 additional deaths from the second wave of the Cholera epidemic. This was followed by over 1150 additional deaths by mid-December 2023 and the designation as a Grade 3 Emergency Hazard Status by the WHO. Because of the high potential for asymptomatic carriers of cholera to develop following a widespread epidemic, additional public health strategies must be vigorously employed including widespread immunization to control and minimize the continued impact of the endemic on community, regional and global wellbeing and hopefully prevent the next epidemic from occurring in Haiti or from spreading to surrounding islands and distant jurisdictions.

Critical route for development of medical student leadership competencies in 35 Pan American Health Organization member states: Ascoping review and thematic analysis.

The Pan American Health Organization has been committed to training physicians in leadership competencies since 2008. However, four reviews on teaching leadership using competency-based education in undergraduate medical education (UME) identified only two of 35 MS: Canada and the USA. Previous reviews did not use a systemic approach or qualitative methodology to explore factors influencing leadership education. Therefore, this review aims to identify facilitating and inhibiting factors in teaching leadership in UME using a scoping review and thematic analysis. Six databases containing grey and indexed literature in English, Spanish, and Portuguese were searched, including a hand search and authors' consultations. Forty-eight documents out of 7849 were selected based on eligibility criteria. Braun and Clarke's thematic analysis guide was used, identifying eight themes: curriculum, intended learning outcomes, teaching methods, assessment, addressing barriers, supporting organisational change, building networks, and developing expertise. Considering these themes, the authors propose a critical route for teaching leadership in UME in the Americas. First, institutional design should consider governance gaps, such as having national and international policies for leadership training in UME with inter-professional, trans-professional, and citizen-focused approaches. There is a pressing need to provide leadership training for physicians and other professionals from government, academia, non-governmental organisations, hospitals, and national and international organisations whose missions are related to health or education. Networking opportunities for stakeholders in leadership education and teacher training is also essential. Second, instructional design reveals knowledge-do gaps in member states (MS) when incorporating leadership into the medical curriculum. This includes using leadership frameworks, defining learning outcomes, and employing assessment and monitoring tools for leadership education. Mechanisms to reduce these gaps in MS include the Equator Network and Evidence-Informed Policy Networks fostering knowledge translation and governance.

Donation and Equitable Access to Organ, Tissue, and Cell Transplants: A Brazilian Perspective on the Strategy and Plan of Action 2019-2030

ObjectiveTo position the Brazilian Transplant System within the context of the 4 Strategic Lines of Action proposed by the Pan-American Health Organization. MethodA specialist analysis was conducted through comparative analyses of the 4 Strategic Lines of Action, objectives, and indicators outlined in the Action Plan, along with the donation and transplantation system in accordance with Brazilian transplantation law. Subsequent to an in-depth review of the document issued by the health authority, a series of meetings involving 8 specialists in organ donation and transplantation were conducted. During these meetings, discussions were carried out with the objective of numerically interpreting each strategy presented in the document, and recommendations constructed. ResultsFour strategies were evaluated and only 2 of them the third (81,3%) and the fourth (90%) do not achieve the indicators to complete the objective related to equitable access to organ, tissue, and cell transplants in Brazil. ConclusionThe recommendations developed carry importance, as they are innovative and contribute to the establishment of priorities when shaping public policies. The report not only highlights indicators that were not satisfactorily met but also provides insights into the recommendations formulated to improve those indicators that have already been achieved and to work toward achieving those that have not yet been realized. Additionally, these recommendations can justify actions and establish priorities for research efforts in the field.

Biotechnological potential of Aspergillus niger L-asparaginase supplemented with Euterpe oleracea mart seed as an alternative source for cervical cancer treatment: a literature review

According to the Pan American Health Organization (PAHO), cancer is one of the leading causes of death in the Americas, with cervical cancer being the third most common, affecting over 56 thousand women in Latin America, and unfortunately, over 28 thousand of them do not survive this disease. This review study aims to present the enzyme L-asparaginase produced by the fungus Aspergillus niger, supplemented with the seed of Euterpe oleracea Mart (açaí), as an alternative treatment source against cervical cancer caused by human papillomavirus (HPV), thus encouraging biotechnological studies with natural products, promoting future benefits that significantly contribute to the treatment of women affected by HPV. Much research has been conducted on the species of fungus Aspergillus niger, which are widely distributed in nature and have the ability to produce various metabolites, notably L-asparaginase. In this sense, studies confirming the efficacy of this enzyme against HPV could signify a breakthrough in the remission or cure of cervical cancer cases in women with such a diagnosis. The flour from the seed of Euterpe oleracea Mart, when used as a substrate for Aspergillus niger, may possess excellent nutritional value, making it a potential producer of L-asparaginase. Additionally, the pulp of E. oleracea fruits is a source of agro-industrial waste, and with the opportunity for utilization, it becomes a source of promising substances for commercial use. This review sought to present L-asparaginase produced by a natural fungus (Aspergillus niger) as an alternative source for in-depth studies on its potential for treating HPV-induced cervical cancer, discussing the use of Euterpe oleracea Mart seed as a supplement for this fungus, drawing attention to the utilization of this agro-industrial waste and proposing a reduction in environmental pollution.

Epidemiological findings, estimates of the instantaneous reproduction number, and control strategies of the first Mpox outbreak in Latin America

BackgroundThe 2022–2023 period marked the largest global Mpox outbreak, with Latin America's situation notably underexplored. This study aims to estimate Mpox's instantaneous reproduction number (R(t)), analyze epidemiological trends, and map vaccination efforts in six Latin American countries. MethodsUtilizing Pan American Health Organization Mpox surveillance data, we examined demographic characteristics, cumulative incidence rates, and epidemic curves, calculated R(t) with weekly sliding windows for each country, alongside a review of vaccination initiatives. ResultsFrom 2022 to 2023, 25,503 Mpox cases and 71 deaths were reported across Argentina, Brazil, Chile, Colombia, Mexico and Peru, with a significant majority (91.8%–98.5%) affecting men, with a mean age of 32–35 years. Maximum R(t) values varied across countries: Argentina (2.63; 0.85 to 5.39), Brazil (3.13; 2.61 to 3.69), Chile (2.91; 1.55 to 4.70), Colombia (3.15; 2.07 to 4.44), Mexico (2.28; 1.18 to 3.75), and Peru (2.84; 2.33 to 3.40). The epidemic's peak occurred between August and September 2022 with R(t) values subsequently dropping below 1. From November 2022, and as of February 2024, only Chile, Peru, and Brazil had initiated Mpox vaccination campaigns, with Colombia launching a Clinical Trial. ConclusionThe peak of the Mpox epidemic in the studied countries occurred before the commencement of vaccination programs. This trend may be then partly attributed to a combination of behavioral modifications in key affected communities and contact tracing local programs. Therefore, the proportion of the at-risk population that remains susceptible is still uncertain, highlighting the need for continued surveillance and evaluation of vaccination strategies.

Incorporating an intersectional gender approach to improve access to maternal and child health screening services

BackgroundIn the Americas, the Pan American Health Organization (PAHO) has promoted initiatives that aim at the elimination of mother-to-child transmitted diseases for over two decades. Although Guatemala has assumed the commitment to improve access and coverage of reproductive and perinatal services, the goals have not yet been reached. Often, the implementation of these efforts is hampered by complexities rooted in social, cultural, and environmental intersections. The objective of this work is to share our experience applying gender intersectionality as a methodological and analytical tool in a participatory research project that aims to improve access to maternal and child health screening services. The study shows the novel strategy that incorporates intersectionality contributing to evidence on how it can be applied to strengthen public health efforts around the implementation of the EMTCT Plus (Elimination of mother-to-child transmission of HIV, Syphilis, Hepatitis B, and Chagas disease) framework, in the mostly rural municipality of Comapa, in Guatemala.MethodsWe applied a participatory methodology, integrating theoretical and methodological frameworks to have an intersectional understanding of health services delivered by both, midwives, and the public health institution, for the prevention, diagnosis, treatment, and follow-up of HIV, Syphilis, Hepatitis B, and Chagas. The data was collected by conducting interviews, focus groups, workshops, and reviewing laboratory databases, guided by five strategies from a cultural appropriateness framework.ResultsThe intersectional analysis shed light on the synergies and gaps of the current efforts and protocols implemented by both the midwives and the Ministry of Health. The services offered for the four diseases were often delivered independently from each other, and a comprehensive educational and communication material strategy was absent. However, our findings will be used to inform consistent, locally relevant, and culturally appropriate educational content for the local population, also following the national policy guidelines.ConclusionsUsing intersectionality as a method and as an analytical tool allowed us to understand the (1) interrelation of diverse social, cultural, and environmental determinants which influence the delivery of health services, as well as (2) the dynamics between the traditional and institutional health systems. (3) Community engagement and the participation of different stakeholders in a consultative process have been fundamental for the conceptual and methodological tenets of this research. (4) Finally, giving a more prominent role to midwives can strengthen sustainability and cultural appropriateness, which is complementary to the delivery of institutional health services.

[Concordance between essential medicines lists and diabetes guidelines in Latin America and the CaribbeanConcordância entre as listas de medicamentos essenciais e diretrizes para diabetes na América Latina e no Caribe].

Conduct an analysis to determine the existence and updating of national essential medicines lists (EMLs) and clinical practice guidelines (CPGs) for the treatment of diabetes in Latin America and the Caribbean (LAC); and compare the medicines included in each country's list and guidelines both with each other and with those of the World Health Organization (WHO). Cross-sectional study. EMLs and CPGs for diabetes were found on the websites of the Pan American Health Organization and national health authorities. Medicines were noted and analyzed according to pharmacological group, based on the fourth level of nomenclature of the Anatomical Therapeutic Chemical (ATC) classification system. F1 scoring was used to assess the proximity of EMLs to the WHO Model List of Essential Medicines (MLEM). Of the total number of countries, 87.2% have EMLs, and 91% have CPGs (78% and 45% updated in the last five years, respectively). Compared to the six hypoglycemic groups of the MLEM, the EMLs had a median (range) of 6 (4-13) and an F1 score of 0.80; This indicates proper alignment. CPGs had a median (range) of 12 (1-12) hypoglycemic drugs compared to eight in the WHO guidelines. CPGs had a median of 15 more drugs than their respective EMLs. While most LAC countries have EMLs and CPGs for diabetes, the lack of concordance among them limits their effectiveness. It is necessary to align the processes and criteria for the development of these two tools for policymaking on medicines.

Alignment and specifics of Brazilian health agencies in relation to the international premises for the implementation of digital health in primary health care: a rhetorical analysis.

Digital health and sustainable development goals have had strong impacts with the COVID-19 pandemic. In Brazil, the health crisis scenario required changes in social welfare programs and policies, based on recommendations from international agencies, such as the UN and WHO. This study aims to analyze the alignment of the arguments of Brazilian and international organizations for the adoption of digital health in Primary Health Care based on the COVID-19 pandemic. This is a qualitative documentary study of the rhetorical analysis type, based on Perelman and Obrechts-Tyteca's Theory of Argumentation. The search for documents was carried out by two independent researchers, between December 2021 and June 2022, through the websites of the World Health Organization, the Pan American Health Organization, the Brazilian Ministry of Health, and the Federal Councils of Medicine and Brazilian nursing, with the terms "digital health," "telehealth," "telemedicine," "e-health," "telehealth," "telenursing," "telemedicine," and "digital health." Twenty official documents were analyzed and identified in terms of context, authorship, authenticity, reliability, nature, and key concepts. The international and Brazilian arguments emphasize the applicability of Information and Communication Technologies (ICTs) in the health field. In logical arguments, based on the structure of reality, international agencies emphasize the overlap between health needs and the conditions for the applicability of ICTs. In Brazil, however, there was a need to regulate the digital practices of health professionals. In the international discourse, in the structuring of reality, there are illustrations of the relationship between the context of the health crisis caused by COVID-19 and the concrete conditions for the applicability of digital health; while in the Brazilian discourse, the need to strengthen an environment conducive to digital health is explicit. The Brazilian alignment in relation to the international premises is evident. Yet, there is a need, socially and economically sustainable, to strengthen the inclusion of digital health in PHC policy.

Surviving covid-19: a multimodal discourse analysis of new media covid-19 vaccination-related pictorials

Abstract This paper explores the communicative acts deployed in covid-19 vaccination-related pictorials circulated on digital media platforms. Seven internet images were purposively sampled with a view to exploring their communicative functions as well as their generic structure. The data, which were culled from the websites of the World Health Organisation, Centre for Disease Control, Pan American Health Organisation and Facebook, were subjected to qualitative analysis. The study deployed van Leeuwen’s Multimodal Discourse Analysis and Yuen’s Generic Structure Potential as theoretical anchor. The multimodal communicative acts are deployed for instructive, illustrative, informative, persuasive, inviting and advisory purposes. Categories such as Lead, Emblem, Announcement and Enhancer are compulsory in the data while Display, Tag and Call-and-Visit Information are non-compulsory elements. This can be catalogued as: ‘Lead^(Display)^Emblem^(Announcement)^(Enhancer)^(Tag)^(Call-and-Visit Information)’. The study contends that the various semiotic resources deployed in the internet-circulated covid-19 images are used not only for informative and other communicative purposes but also to evoke attitudinal change towards and encourage widespread acceptance of the covid-19 vaccines.

Evaluation of a Chatbot Powered by ChatGPT for the Preliminary Diagnosis of Dengue

Dengue poses a public-health challenge in several regions. Early detection is essential to reduce the impact of a condition, and artificial intelligence (AI) and chatbots provide new opportunities to enhance diagnosis. This study evaluates the effectiveness of integrating a chatbot with ChatGPT version GPT-3.5 for the preliminary diagnosis of dengue and its contribution to timely detection. To evaluate this, two types of tests were conducted using a dataset of 30 dengue cases. In the first test, the chatbot was evaluated without being trained with dengue symptoms. In the second test, however, the model was trained using dengue symptoms obtained from official websites such as the World Health Organization (WHO) and the Pan American Health Organization (PAHO). The performance of the chatbot was evaluated using the confusion matrix, performance metrics, and user satisfaction. The results of the second test showed impressive performance, with accuracy, sensitivity, and specificity of 100%. This surpassed the first test, which achieved accuracy, sensitivity, and specificity of 83%, 80%, and 90%, respectively. In addition, 15 users reported positive satisfaction, with an overall average rating of 4.25 out of 5. In conclusion, these results highlight the effectiveness of the chatbot as a valuable public health tool for the early detection and management of dengue. It is important to note that, despite the remarkable diagnostic results of the chatbot integrated with ChatGPT, it does not replace medical judgment.

Exploring the Genomic Dynamics of the Monkeypox Epidemic in Paraguay.

In recent months, Paraguay has been grappled with a notable monkeypox outbreak, straining its healthcare infrastructure. The sudden spike in cases underlines the imperative need for a comprehensive understanding of the virus's dynamics, enabling the formulation of robust containment measures. To address this challenge, our team joined forces with the Central Public Health Laboratory of Asunción and the Pan-American Health Organization. Through this collaboration, we employed portable whole-genome sequencing combined with phylodynamic analysis to examine the MPXV strains circulating in Paraguay. Our genomic monitoring approach has produced the first 30 whole-genome sequences from Paraguay, all of which were identified under lineage IIb. Interestingly, our data suggest that the origin of the monkeypox virus in Paraguay at the beginning of 2022 can be traced back to Brazil. This introduction subsequently catalyzed further community spread that was further exacerbated by several independent introduction events as time progressed. These findings not only shed light on the transmission patterns of the virus but also highlight the pivotal role such insights play in sculpting effective response strategies and driving impactful public health measures. Furthermore, our findings strongly advocate intensified surveillance at international borders, ensuring swift detection and proactive countermeasures against potential outbreaks in the future.

Harmonization of individual case safety reports transmission requirements among PAHO reference authorities: a review of their current regulation.

To perform optimal monitoring of the safety profile in the postmarketing phase, Marketing Authorization Holders and National Regulatory Authorities (NRAs) must evaluate the adverse drug reactions (ADRs) that occurred and characterize their nature, frequency, and severity. Management is possible through Individual Case Safety Reports (ICSRs), which are the reports of organized and processed data. Globally, the International Council for Harmonisation (ICH) E2B guideline suggests harmonized activities for the ICSR electronic content and transmission. In America, the Pan American Health Organization (PAHO) is the agency responsible to implement cooperation among its members, which are recognized as National Regulatory Authorities of Reference (NRARs) such as Argentina, Brazil, Canada, Chile, Colombia, Cuba, Mexico, and the United States. PAHO published the 'Good Pharmacovigilance Practices for the Americas' suggesting improvement and harmonization in the region. After reviewing the regulatory framework, it is assumed that all NRARs have a regulated ICSR transmission system (i.e. a systematic vigilance system for collecting, analyzing, and disseminating information from ADRs). However, significant differences exist, such as the requirement for social media vigilance, expedited and non-expedited ICSRs, coding, severity, and transmission. The volume of ICSRs has significantly increased, due to using electronic standards managed by the NRAs, which facilitates early identification of new ADRs, allowing the implementation of novel minimization activities, contributing to the continuous assessment of the benefit-risk balance of medicines. Nevertheless, there is still area for improvement, especially in Latin America.
