BACKGROUND. Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The burden of asthma in children is increasing in low- and middle-income countries and remains under-recognised and poorly managed.
OBJE...CTIVES. To quantify the burden of asthma in the South African (SA) population and identify the risk factors associated with disease severity in the local context.
METHODS. The SA Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The epidemiology task group reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system.
CONCLUSIONS. Asthma in children remains a common condition, which has shown an increasing prevalence in urban and rural populations of SA. Of concern is that almost half of children in urban communities experience severe asthma symptoms, and many asthmatics lack a formal diagnosis and thus access to treatment. Exposure to tobacco smoke and living in highly polluted areas increase the severity of wheezing in young children.

Asthma is the most common chronic disease in children, imposing a consistent burden on health system. In recent years, prevalence of asthma symptoms became globally increased in children and adolescents, particularly in Low-Middle Income Countries (LMICs). Host (genetics, atopy) and environmental fa...ctors (microbial exposure, exposure to passive smoking and air pollution), seemed to contribute to this trend. The increased prevalence observed in metropolitan areas with respect to rural ones and, overall, in industrialized countries, highlighted the role of air pollution in asthma inception. Asthma accounts for 1.1% of the overall global estimate of “Disability-adjusted life years” (DALYs)/100,000 for all causes. Mortality in children is low and it decreased across Europe over recent years. Children from LMICs particularly suffer a disproportionately higher burden in terms of morbidity and mortality. Global asthma-related costs are high and are usually are classified into direct, indirect and intangible costs. Direct costs account for 50–80% of the total costs. Asthma is one of the main causes of hospitalization which are particularly common in children aged < 5 years with a prevalence that has been increased during the last two decades, mostly in LMICs. Indirect costs are usually higher than in older patients, including both school and work-related losses. Intangible costs are unquantifiable, since they are related to impairment of quality of life, limitation of physical activities and study performance. The implementation of strategies aimed at early detect asthma thus providing access to the proper treatment has been shown to effectively reduce the burden of the disease.

Data on asthma aetiology in Africa are scarce. We investigated the risk factors for asthma among schoolchildren (5–17 years) in urban Uganda. We conducted a case-control study, among 555 cases and 1115 controls. Asthma was diagnosed by study clinicians. The main risk factors for asthma were tertia...ry education for fathers (adjusted OR (95% CI); 2.32 (1.71–3.16)) and mothers (1.85 (1.38–2.48)); area of residence at birth, with children born in a small town or in the city having an increased asthma risk compared to schoolchildren born in rural areas (2.16 (1.60–2.92)) and (2.79 (1.79–4.35)), respectively; father’s and mother’s history of asthma; children’s own allergic conditions; atopy; and cooking on gas/electricity. In conclusion, asthma was associated with a strong rural-town-city risk gradient, higher parental socio-economic status and urbanicity. This work provides the basis for future studies to identify specific environmental/lifestyle factors responsible for increasing asthma risk among children in urban areas in LMICs.

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.

The 2020 Report analyzes global health spending for 190 countries from 2000 to 2018 and provides insights as to the health spending trajectory from the MDG era to the SDG era prior to the crisis of 2020. The report shows that global spending on health continually rose between 2000 and 2018 and reach...ed US$ 8.3 trillion or 10% of global GDP. The data also show that out-of-pocket spending has remained high in low and lower-middle income countries, representing greater than 40% of total health spending in 2018. We also report and summarize the data on expenditures for PHC, as well as by disease and intervention, including for immunization. The report also analyzes the available data on budget allocation in response to the COVID-19 crisis. In addition, we combine World Bank/IMF projections of the macroeconomic and fiscal impact of the crisis with an analysis of the historical determinants of health spending patterns and UHC indicators, and based on this, we draw out the likely implications of 2020 for future health spending, highlighting key policy and monitoring concerns.

Providing quality, stigma-free services is essential to equitable health care for all and achieving global HIV goals and broader Sustainable Development Goals related to health. Every person has the right to the highest attainable standard of physical and mental health. Countries have a legal obliga...tion to develop and implement legislation and policies that guarantee universal access to quality health services and address the root causes of health disparities, including poverty, stigma and discrimination.
The health sector is uniquely placed to lead in addressing inequity, assuring safe personcentred care for everyone and improving social determinants of health by overcoming taboos and discriminatory or stigmatizing behaviours associated with HIV, viral hepatitis and sexually transmitted infections (STIs). Improving health care quality and reducing stigma work together to enhance health outcomes for people living with HIV. Together, they make health care services more accessible, trustworthy and supportive. This encourages early diagnosis, consistent treatment and improved mental well-being. Thus, people living with HIV are more likely to engage with and benefit from health care services, leading to improved overall health.

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.

Trustworthy, evidence-based health guidelines form the basis of national policies affecting both patients and health-care workers. Emphasizing the link between robust evidence and people’s trust in their health systems, Dr Hans Henri P. Kluge, WHO Regional Director for Europe said at the launch ev...ent, “Trust and transformation are key words for us, especially when we talk about improving and strengthening our health systems. Transformation should first and foremost serve the interests of patients and health-care workers”.
While it is not always easy to demonstrate the immediate effect of guidelines on people’s health, there is no viable alternative to utilizing guidelines based on the best available evidence.
Yet, developing robust guidelines remains a challenge for most countries. “Guidelines need to be both simple to use and timely, they need to address people’s real needs, especially at the local level, and should ultimately reflect the resources available,” said Dr Natasha Azzopardi-Muscat, Director, Country Health Policies and Systems, WHO/Europe. “This means that any successful guideline needs to be adjusted and adapted to local contexts and realities.”
