Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

L’objectif de ces lignes directrices est de présenter l’ensemble complet des recommandations et des énoncés de meilleures pratiques de l’OMS en matière d’avortement
Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gaps are much more pronounced in LMIC. Barriers at the... patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality.

The World Heart Federation (WHF) commenced a Roadmap initiative in 2015 to reduce the global burden of cardiovascular disease and resultant burgeoning of healthcare costs. Roadmaps provide a blueprint for implementation of priority solutions for the principal cardiovascular diseases leading to death... and disability. Atrial fibrillation (AF) is one of these conditions and is an increasing problem due to ageing of the world’s population and an increase in cardiovascular risk factors that predispose to AF. The goal of the AF roadmap was to provide guidance on priority interventions that are feasible in multiple countries, and to identify roadblocks and potential strategies to overcome them.

Climate change is one of the biggest crises of our time. Climate threats range from higher temperatures, heavy rainfalls and floods, erratic precipitation, droughts, desertification, and land degradation. This has negative implications on the quality and quantity of natural resources, such as land a...nd water, agricultural productivity, rural livelihood options, food prices, and nutrition security, particularly when there is a lack of adaptation capacities and preparedness measures (Pacillo, 2024). Farmers are at the forefront of the climate crisis where their livelihoods are being jeopardized, and they are faced with many challenges to secure water, energy, and agriculture inputs, and maintain agriculture productivity. This heightens the risk of competition over natural resources and aggravates grievances and structural inequalities related to land rights and ownership as well as land access, management, and governance. In Africa, land-related issues are among the triggers of many violent disputes (Medina et al, 2024). For instance, communal violence in Nigeria and Sudan is tied to competition over scarce fertile land and poor resource governance (Bruce and Bourdeaux, 2013).

Long-term polio vaccine security – the timely, sustained, and uninterrupted supply of suitable types of affordable, quality-assured polio vaccines – is essential in the global effort to achieve and maintain a polio free world. However, fragmented approaches and short-term planning pose considera...ble challenges to securing long-term polio vaccine security.
This framework is designed to enhance the efforts of existing structures and workstreams within the Global Polio Eradication Initiative (GPEI) and other stakeholders by improving communication and coordination on vaccine security. Ensuring vaccine security is crucial for maintaining a timely, sustained, and uninterrupted supply of affordable, quality-assured polio vaccines in the global fight to achieve and sustain a polio-free world. However, challenges such as fragmented approaches, short-term planning, a dynamic policy environment, and a diverse product pipeline present significant risks to long-term vaccine security. This framework emphasizes the need for alignment and coordination across key polio operational domains, including Poliovirus Containment, Research and Development, and Vaccine Manufacturing and Supply. It also underscores the critical role of normative frameworks and policies in shaping long-term vaccine strategies that guide these operational areas. Additionally, it highlights the importance of cross-cutting elements such as financing and access to resources, along with the integration of communication, coordination, and advocacy efforts, as essential enablers for achieving vaccine security. To secure long-term vaccine supply, it is imperative to enhance alignment and strengthen coordinated efforts across workstreams and with stakeholders, including vaccine manufacturers.
Recognizing that vaccine security is an ongoing endeavor, requiring continuous monitoring and adaptation, this framework will undergo regular updates and revisions. Initially, the management of the framework will be carried out by the GPEI Vaccine Supply Group (VSG).

As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.
