.Chronic manifestations of Chagas disease present as disabling and life-threatening condi-tions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mech...anisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particu-larly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

To support its R&D activities on Chagas disease, DNDi launched the Chagas Clinical Research Platform (CCRP). The platform brings together partners, experts, and stakeholders to provide support for evaluation and development of new treatments for Chagas disease. The patient-centred platform aims to f...acilitate clinical research, provide a forum for technical discussions, develop a critical mass of expertise, and strengthen institutional research capacities. In addition, it identifies and reviews priority needs, works towards standardization of methodology to assess drug efficacy and reviews alternatives for using current approved drugs (new schemes, doses, combination) and special scenarios (resistance).

The meeting was held from 26 to 27 March 2018 to review and discuss the following topics:
Advances and challenges in the use of fTLC, and new approaches to detecting mycolactone using monoclonal antibodies (mAbs).
The status of development of rapid diagnostic tests (RDTs) targeting the MUL..._3720 protein.
The role of PCR as a reference test, and hurdles in providing a confirmatory diagnosis and in establishing a quality assurance programme.
New molecular tools with potential for implementation at a level lower than in the national or regional reference laboratory, such as loop-mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA).
The need to harmonize and standardize methods for collection and preparation of specimens, so samples can be referred for diagnosis and stored for evaluation of new diagnostic tests in optimal conditions.
Barriers to accessing early diagnosis and treatment, including coordination at the programme level, and lack of adequate diagnostic tools.
Defining target product profiles (TPPs) to guide the development of new diagnostic tools that can be applied at different levels of the health system. Participants agreed that two TPPs would be developed to address the current gaps: (i) a rapid test for BU diagnosis at the primary health-care level; and (ii) a test for diagnosis of BU that can also assist in treatment monitoring and differential diagnosis at the district hospital or reference centre.

Antimicrobials are medicines, including antibiotics, antivirals, antifungals, and antiparasitics, that are used to prevent and treat infections in humans, animals, and plants. Antimicrobial Resistance (AMR) arises when bacteria, viruses, fungi, and parasites no longer respond to these medicines, ren...dering them ineffective and making infections more difficult to treat. This resistance increases the risk of disease spread, severe illness, disability, and death. Although AMR is a natural phenomenon driven by genetic
changes in pathogens, it is significantly accelerated by human activities such as the misuse and overuse of antimicrobials in healthcare, agriculture, and animal husbandry.

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).

People with disabilities experience significant health inequalities. In Malawi, where most individuals live in low-income rural settings, many of these inequalities are exacerbated by restricted access to health care services. This qualitative study explores the barriers to health care access experi...enced by individuals with a mobility or sensory impairment, or both, living in rural villages in Dowa district, central Malawi. In addition, the impact of a chronic lung condition, alongside a mobility or sensory impairment, on health care accessibility is explored.

Asthma is the most common chronic respiratory disease among school-going adolescents worldwide. However, the burden of severe asthma is highest in Sub-Saharan Africa. This study aimed to explore teachers’ perceptions of asthma care across six African countries. We conducted focus group discussions... (FGDs) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. FGDs were conducted in Kumasi(Ghana), Blantyre (Malawi), Lagos (Nigeria), Durban (South Africa), Kampala (Uganda), and Harare (Zimbabwe) between 01 November 2020 and 30 June 2021. We identified two key themes related to asthma care; barriers to asthma care and suggestions to improve the care of adolescents with asthma. Barriers reported by teachers included a lack of knowledge and skills among themselves, adolescents, and caregivers. In addition, some traditional beliefs of teachers on asthma exacerbated challenges with asthma care in schools. Regarding suggestions, most teachers identified a need for all-inclusive asthma training programmes for teachers, adolescents and caregivers, focusing on acute episodes and mitigating triggers. Utilising teachers with personal experiences with asthma to advocate and support these initiatives was suggested. Further suggestions included the need for annual screening to enable early identification of adolescents with asthma and clarify restrictions on teachers administering asthma medications. Teachers across African schools identify multiple barriers to asthma care. Structured school education programs and annual asthma screening are key to addressing some barriers to care.

The Government of Malawi’s Health Sector Strategic Plan II highlights the importance of service integration; however, in practice, this has not been fully realized. We conducted a mixed methods evaluation of efforts to systematically implement integrated family planning and immunization services i...n all health facilities and associated community sites in Ntchisi and Dowa districts during June 2016–September 2017. Methods included secondary analysis of service statistics (pre- and postintervention), focus group discussions with mothers and fathers of children under age one, and in-depth interviews with service providers, supervisors, and managers. Results indicate statistically significant increases in family planning users and shifts in use of family planning services from health facilities to community sites. The intervention had no effect on immunization doses administered or dropout rates. According to mothers and fathers, benefits of service integration included time savings, convenience, and improved understanding of services. Provision and use of integrated services were affected by availability of human resources and commodities, community linkages, data collection procedures and availability, sociocultural barriers, organization of services, and supervision and commitment of health surveillance assistants. The integration approach was perceived to be feasible and beneficial by clients and providers.

This study compared clinical and autopsy findings for three asbestos-related diseases (asbestosis, mesothelioma and lung cancer) in former asbestos mineworkers, and explored factors that influenced agreement between clinical and autopsy findings using data from two compensation systems. In South Afr...ica, statutory compensation for occupational lung diseases in mineworkers makes provisions for autopsy examinations of the cardio-respiratory organs at the National Institute for Occupational Health (NIOH) in Johannesburg. In addition, the Johannesburg-based Asbestos Relief Trust and Kgalagadi Relief Trust (the “Trusts”) compensate individuals with defined asbestos-related diseases who worked in or lived near qualifying asbestos mining or processing operations. The Trusts also compensate dependents of deceased qualifying mineworkers and therefore encourage statutory autopsies for the detection of previously undiagnosed asbestos-related disease or disease that may have progressed to higher compensation grades.

The article "Asthma in South African adolescents: a time trend and risk factor analysis over two decades" investigates the prevalence and risk factors for asthma in Cape Town adolescents from 2002 to 2017. The study finds that while the overall prevalence of asthma remained similar, the severity of ...the condition increased significantly. Risk factors for asthma and severe cases include smoking, pet exposure, outdoor pollution, and living in informal housing. Despite these trends, underdiagnosis remains a concern, as only one-third of adolescents with current or severe asthma had been formally diagnosed. The article emphasizes the need for better public health strategies to address environmental exposures and improve asthma diagnosis and treatment.

This study identifies barriers and provides recommendations to improve asthma care in children across sub-Saharan Africa, where qualitative data is lacking despite high rates.
The combined effects from ambient (outdoor) air pollution and indoor (household, in particular) air pollution cause approximately 7 million premature deaths every year, largely as a result of increased mortality from stroke, IHD, COPD, lung cancer and acute respiratory infections (1). Air pollution ...can occur in both the outdoor and indoor environments. Cook-stoves in homes, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Air pollutants with the strongest evidence for adverse health outcomes include particulate matter (PM; both PM 2.5 (i.e. particles with an aerodynamic diameter
equal to or less than 2.5 μm) and PM10 (i.e. particles with an aerodynamic diameter equal to or less than 10 μm), ozone (O 3), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ) and carbon monoxide (CO). Air pollution is however composed of many more pollutants (1).
