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 World Health Organization (WHO) has identified mental health as an integral component of the COVID-19 response. Its rapid assessment of service delivery for mental, neurological and substance use (MNS) disorders during the COVID-19 pandemic, on which this report is based, is the first attempt to... measure the impact of the pandemic on such services at a global level. The data were collected through a web-based survey completed by mental health focal points at ministries of health between June and August 2020. The questionnaire covered the existence and funding of mental health and psychosocial support (MHPSS) plans, the presence and composition of MHPSS coordination platforms, the degree of continuation and causes of disruption of different MNS services, the approaches used to overcome these disruptions, and surveillance mechanisms and research on MNS data.

Low-income countries face many contextual challenges to manage healthcare technologies effectively, as the majority are imported and resources are constrained to a greater extent. Previous healthcare technology management (HTM) policies in Benin ha...ve failed to produce better quality of care for the population and cost-effectiveness for the government. This study aims to identify and assess the main problems facing HTM in Benin’s public health sector, as well as the ability of key actors within the sector to address these problems.

Effective risk communication requires the alignment of complex factors including trust between the communicator and the audience(s), audience involvement, and emotional responses to risk. Risk communication is especially challenging now as new media changes the landscape for both
communicators and... their audiences. Viewed as a discussion of the most important findings for risk communicators and managers, this report delves into research-driven recommendations for effective risk communication practices.
