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.

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.

Mpox is a zoonotic disease caused by a double-stranded DNA virus that belongs to the Orthopoxvirus genus of the Poxviridae family. The disease presents with symptoms similar to smallpox but with a lesser severity. It was first discovered in 1958 when two outbreaks of a poxlike disease occurred in co...lonies of monkeys kept for research, hence the name ‘mpox. The first human case of mpox was recorded in 1970 in the Democratic Republic of the Congo (DRC), which has subsequently spread to other central and western African countries. There are two known clades of the virus: clade I and clade II. Clade I, which is most frequently reported from countries in Central Africa, tends to be more severe than clade II. Cameroon is the only country known to harbour both clades.

The Global Asthma Report (GAR) 2022, prepared by the Global Asthma Network (GAN), is the fourth such report (others 2011, 2014, 2018). GAN builds upon the work of the International Study of Asthma and Allergies in Childhood (ISAAC) and The International Union Against Tuberculosis and Lung Disease (T...he Union) to monitor asthma and improve asthma care, particularly in low- and middle-income countries (LMICs).

Research globally has shown that metered dose inhaler (MDI) technique is poor,
with patient education and regular demonstration critical in maintaining correct use of
inhalers. Patient information containing pictorial aids improves understanding of medicine
usage; however, manufacturer leaflets i...llustrating MDI use may not be easily understood by

Silicosis is not a new disease; the impact of silica dust on respiratory function was observed by Hippocrates in 430 B.C. and in the 16th century by Agricol. In 1713, Rammazini described silicotic nodules in post-mortems of stone cutters presenting with respiratory symptoms. In the mid-late 1800s,... the introduction of mechanized tools in the mining sector rapidly increased levels of silica exposure, resulting in an increase in cases and our understanding of silicosis.

Since February 24th, 2022, the beginning of Russia’s aggression against Ukraine, more than 80,000 women were expected to give birth. Therefore, understanding the impact of war on the perinatal health of women is an important requisite to improve perinatal care. This narrative synthesis has two mai...n purposes: on one hand, it aims to summarize the current evidence available based on perinatal health outcomes and care among perinatal women; on the other, it attempts to identify the gaps still present in research in relation to perinatal care.

As our world changes, so too does the burden of disease. Globalisation, evolving trade and consumption patterns, and increased access to life-saving medical care are just some of the factors that have transformed the global health landscape.

In the course of implementing a recently funded network of hubs for building capacities in mental health service development, training, and research (RedeAmericas), the peer support workers are being introduced into the mental health workforce in three Latin American countries for the very first tim...e. They will be part of a team, along with community mental health workers, that provides a modified Critical Time Intervention to individuals with severe psychiatric disorders living in the community. This article reviewed the background of this increasingly widespread development, and discussed its merits, as well as potential obstacles within local contexts.

In September 2021, the UN and its partners presented a response plan to mitigate the impact of the water crisis in northern and north-east Syria which requested US$200 million to assist up to 3.4 million of the over five million people estimated to be affected by the water crisis in northern Syria b...etween September 2021 and February 2022. Under the auspices of the 2022-2023 Syria Humanitarian Response Plan, this updated water response plan presents the most recent needs based on latest forecasts and is a continuation of the earlier plan presented in 2021. It covers the needs from all response modalities/areas1 for Syria, aims to assist 5 million people until December 2022 and requests $226.2 million.

Vitamin A deficiency is a risk factor for blindness and for mortality from measles and diarrhoea in children aged 6–59 months. We aimed to estimate trends in the prevalence of vitamin A defi ciency between 1991 and 2013 and its mortality burden in low-income and middle-income countries.
