Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

he aetiology of asthma and allergic disease remains poorly understood, despite considerable research. The International Study of Asthma and Allergies in Childhood (ISAAC), was founded to maximize the value of epidemiological research into asthma and allergic disease, by establishing a standardized m...ethodology and facilitating international collaboration. Its specific aims are: 1) to describe the prevalence and severity of asthma, rhinitis and eczema in children living in different centres, and to make comparisons within and between countries; 2) to obtain baseline measures for assessment of future trends in the prevalence and severity of these diseases; and 3) to provide a framework for further aetiological research into genetic, lifestyle, environmental, and medical care factors affecting these diseases. The ISAAC design comprises three phases. Phase 1 uses core questionnaires designed to assess the prevalence and severity of asthma and allergic disease in defined populations. Phase 2 will investigate possible aetiological factors, particularly those suggested by the findings of Phase 1. Phase 3 will be a repetition of Phase 1 to assess trends in prevalence.

The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. To reach this goal in children with asthma, ongoing monitoring is essential. While all components of asthma, such as symptoms, lung function, bronchial hyperresponsiveness and inflammation, may exist i...n various combinations in different individuals, to date there is limited evidence on how to integrate these for optimal monitoring of children with asthma. The aims of this ERS Task Force were to describe the current practise and give an overview of the best available evidence on how to monitor children with asthma.
22 clinical and research experts reviewed the literature. A modified Delphi method and four Task Force meetings were used to reach a consensus.
This statement summarises the literature on monitoring children with asthma. Available tools for monitoring children with asthma, such as clinical tools, lung function, bronchial responsiveness and inflammatory markers, are described as are the ways in which they may be used in children with asthma. Management-related issues, comorbidities and environmental factors are summarised.
Despite considerable interest in monitoring asthma in children, for many aspects of monitoring asthma in children there is a substantial lack of evidence.

In Latin America and the Caribbean (LAC), one maternal death was registered every hour in 2020. That same year, the trend in the maternal mortality ratio (MMR) for the Region of the Americas regressed alarmingly and unprecedentedly to the levels seen two decades ago. In addition to indicating a wors...ening of health outcomes, these figures also signal a deepening of inequalities, representing thousands of individual, unacceptable tragedies that in most cases could have been preventable. Maternal death is the result of a multifactorial process in which structural elements such as the economic system, environmental conditions, and culture interact. Other factors related to social inequality are also present, such as racism, poverty, gender inequality, and lack of access to the education system. The current situation calls for urgent mobilization of the health systems of LAC countries in order to strengthen efforts to combat maternal mortality, especially in countries that are still far from achieving the SHAA2030 regional target. For this reason, a preventive, health-promoting, life-course-based approach is needed, with models of care centered on women, families, and the community Scientific evidence shows that health systems with a solid foundation in primary health care (PHC) achieve better outcomes, greater equity, and reduced health expenditures. To address this, PAHO proposes a strategy, aimed primarily at women who are in the most vulnerable situation, who are the ones who represent the greatest burden of maternal mortality, to accelerate the reduction of maternal mortality in the Region of the Americas, based on the expansion and strengthening of PHC.

Medical devices are used for the prevention, diagnosis and treatment of illness and diseases and for rehabilitation. WHO developed guidance on medical device donation in 2011, which has been now reviewed, with new evidence, new references on considerations for medical device solicitation and provisi...on, risks associated with inappropriate donations, the responsibilities of donors and recipient, and the steps they should follow before, during and after a donation. It includes three sections: description of major problems that may be faced during the donation process, listing of best practices for donors and recipients and addressing situations requiring special attention. It also has three annexes for further reading: the criteria for the acceptability of a donation, literature review on donations of medical devices between 2010 and 2023 and a flyer. This document is intended to improve the quality of medical devices donations, including medical equipment, single-use medical devices and in-vitro diagnostics, to provide maximum benefit to all stakeholders. The considerations can be used to develop institutional or national policies and regulations for medical devices donations. This document is intended for use by any organization, expert or practitioner involved in the donation, procurement, management of medical devices, including health workers, biomedical engineers, health managers, policymakers, donors, nongovernmental organizations and academic institutions.

The Sustainable Development Goals (SDGs) call for major societal transformations that will require significant fiscal outlays as well as private investments. The fiscal outlays cover public investments, the public provision of social services, and social protection for vulnerable populations. The ke...y message of this paper, building on recent reports by the IMF and SDSN (IMF, 2019b; SDSN, 2018) is that the governments of Low-Income Developing Countries (LIDCs) will require a substantial increase in fiscal (budget) revenues, far beyond what they can achieve by their own fiscal reforms. For this reason, SDG financing will require substantial international cooperation to enable the LIDCs to finance their SDG fiscal outlays. One important source of increased revenues should be the globally coordinated taxation of ultra-high-net worth assets. Today’s ultra-rich should help to pay for the survival and basic needs of the world’s poorest people.

The UN’s SDG Stimulus Plan, which calls for additional liquidity, effective debt restructuring and the expansion of development financing, has the potential to free up significant fiscal space in developing economies. For 52 most debt-vulnerable economies, a 30 percent haircut of 2021 public exter...nal debt stock could lower debt service payments in 2022–2029 by between US$44 billion and $148 billion, depending on the participation of various creditor classes. For all developing economies, a 40 percent “refinancing” of their 2021 bond debt stock to average official creditor rates could amount to a $121 billion savings on interest payments in 2022–2029. Against the backdrop of growing economic and geopolitical fragmentation, this policy brief describes building blocks for exiting the crisis.

This paper has been prepared to inform discussion at the conference “Beating the DRUM - Domestic Resource Use and Mobilization for accelerating progress towards SDG3,”. Many countries face critical shortfalls in domestic resource use and mobilization (DRUM) for health, threatening to push health... goals out of reach. DRUM failures weaken human capital formation, a vital input to economic growth. Countries need more and better health spending. The first step is to apply already-proven DRUM solutions, adapting them to new contexts. However, in many countries, even the best achievable DRUM performance will not be enough. New solutions are needed, including private-sector engagement and a next generation of DAH. The “Beating the DRUM” conference offers a platform for countries and partners to dialogue and build joint strategy. While each country’s situation is unique, shared lines of action are emerging.

In 2023, the World Health Organization was responding to 72 health emergencies, including 19 grade-3 emergencies which required the highest level of activation, reaching millions of people. The annual report on WHO’s response to health emergencies in 2023 outlines the increasingly critical role of... WHO at global, regional and country levels, and across the key elements of effective emergency response, including emergency coordination and planning, operational and logistic support, and community engagement and protection. The huge scale and complexities of health emergencies in the 21st century require a strategic shift towards not only meeting the immediate needs of vulnerable communities, but also building community and health system resilience to all hazards – a challenge that both WHO and its partners must continue to meet.

Todos los países de la Región de las Américas en los que la malaria es endémica han asumido el reto de eliminar la enfermedad y de poner en marcha intervenciones para orientar sus programas y estrategias de salud en esa dirección. Esta versión simplificada y más operativa del Manual para la e...stratificación según el riesgo de malaria y la eliminación de focos de transmisión, dirigida al personal de campo, orienta sobre cómo implementar las acciones básicas de eliminación de la malaria. Se propone orientar un cambio en la operación de malaria con la atención centrada en abordar los focos y la organización de la operación en el nivel más local. El documento parte de la necesidad de identificar y definir un ámbito operativo (el foco o microárea) en donde se pone en práctica una intervención programática concreta (DTI-R) que, si bien es estandarizada a nivel nacional, debe ser ante todo guiada por la comprensión de la dinámica de la transmisión a nivel local

Health system resilience is not an inevitable byproduct of any investment in health but must be intentionally programmed and developed with necessary input, investment and contextualization. This technical product aims to guide national, subnational, and global health actors to operationalize the co...ncept of health system resilience for advancement of universal health coverage, health security and ultimately better health for all. It supports the translation of relevant conceptual guidance and high-level recommendations into practical actions.
The specific objectives are to:
present a concise overview of the concept of health system resilience;
provide a roadmap outlining practical and foundational steps for building health system resilience to be adapted to different contexts;
share examples of actions and tools, including stakeholder roles, to support country application of the roadmap.
The target audience for this work is the various stakeholders involved in strengthening health systems and public health including management of emergencies (from prevention and preparedness to response and recovery) and other public health challenges in countries. This ranges from the donors, policy-makers and decision-makers at global, national and subnational levels to the implementing institutions and line managers of health system functions and services across the health system building blocks.

ince the introduction of multidrug therapy (MDT), there has been significant progress in reducing the prevalence of leprosy and the occurrence of new cases. Global strategies have evolved with progress in reducing the disease burden. Encouraged by the decrease in the number of cases on treatment, th...e World Health Assembly passed a resolution calling on Member States to accelerate efforts towards global elimination of leprosy as a public health problem by 2000.
Most countries reached the milestone by 2010. The global strategies for 2006–2015 focused on sustaining high-quality leprosy services and early diagnosis. Reduction in the disease burden was measured in terms of grade-2 disability (G2D) or visible deformities in new cases. Since 2016, the strategies have included reduction of stigmatization of people with leprosy.

WHO convened the fifth stakeholders meeting on the elimination of HAT due to infection with Trypanosoma brucei gambiense (g-HAT) and Trypanosoma brucei rhodesiense (r-HAT) in Geneva, Switzerland, on 7–9 June 2023. The meeting was held again in person after the coronavirus disease (COVID-19) pandem...ic and jointly for both forms of the disease. The previous meetings on g-HAT held in 2014, 2016 and 2018, as well as on r-HAT in 2015, 2017 and 2019, and jointly for g-HAT and r-HAT in 2021 (8) reinforced the partnership and commitment for HAT elimination and structured the mechanisms of collaboration within the WHO network for HAT elimination. The network includes NSSCPs, groups developing new tools, international and nongovernmental organizations involved in disease control, and donors.
Fewer than 1000 cases of HAT annually have been reported over the past 5 years, which is a historic achievement. The area at risk has been substantially reduced. The elimination of HAT as a public health problem at the global level has been achieved.
The new road map for neglected tropical diseases (NTDs) 2021−2030 (“the road map”) with the target to interrupt the transmission of g-HAT requires the strengthened and sustained efforts of all stakeholders, national authorities and partners, under WHO coordination. It will take disproportionally high efforts and innovative strategies to find the last cases of g-HAT and neutralize its transmission. Given the limited resources and other competing public health priorities, this is a challenge that requires our joint commitment.

Poor diets are the major cause of death and disease globally, driving high levels of obesity and noncommunicable diseases. Cheap, heavily marketed, ultra-processed, energy-dense and nutrient-poor food and drinks that are high in fat, sugar and salt play a major role. The high-sugar content of these ...products leads to consumption levels much higher than recommended. The World Health Organization recommends that sugar intake should be reduced to just 5% of energy intake by using fiscal policies and food and drink reformulation strategies. Over the previous decade, the government of the United Kingdom of Great Britain and Northern Ireland has implemented several policies aimed at reducing sugar intake. We compare the soft drinks industry levy and the sugar reduction programme, examining how differences in policy design and process may have influenced the outcomes. Success has been mixed: the mandatory levy achieved a reduction in total sugar sales of 34.3%, and the voluntary reduction programme only achieved a 3.5% reduction in sugar levels of key contributors to sugar intake (despite a target of 20%). Both policies can be improved to enhance their impact, for example, by increasing the levy and reducing the sugar content threshold in the soft drinks industry levy, and by setting more stringent subcategory specific targets in the sugar reduction programme. We also recommend that policy-makers should consider applying a similar levy to other discretionary products
that are key contributors to sugar intake. Both approaches provide valuable learnings for future policy in the United Kingdom and globally
