osure and poverty in 211 countries and territories. Using the World Health Organization’s (WHO) 2021 revised fine particulate matter (PM2.5) thresholds, we show that globally, 7.3 billion people are directly exposed to unsafe average annual PM2.5 concentrations, 80 percent of whom live in low- and middle-income countries. Moreover, 716 million of the world’s lowest income people (living on less than $1.90 per day) live in areas with unsafe levels of air pollution, especially in Sub-Saharan Africa. Air pollution levels are particularly high in lower-middle-income countries, where economies tend to rely more heavily on polluting industries and technologies. These findings are based on high-resolution air pollution and population maps with global coverage, as well as subnational poverty estimates based on harmonized household surveys.

Background
The objective of this study was to investigate the effects of reduction, cessation, and resumption of smoking on cancer development.
Methods
The authors identified 893,582 participants who currently smoked, had undergone a health scr
...
eening in 2009, and had a follow-up screening in 2011. Among them, 682,996 participated in a third screening in 2013. Participants were categorized as quitters, reducers I (≥50% reduction), reducers II (<50% reduction), sustainers (referent), or increasers (≥20% increase). Outcome data were obtained through December 31, 2018.
Results
Reducers I exhibited a decreased risk of all cancers (adjusted hazard ratio [aHR], 0.96; 95% confidence interval [CI], 0.93-0.99), smoking-related cancers (aHR, 0.95; 95% CI, 0.92-0.99), and lung cancer (aHR, 0.83; 95% CI, 0.77-0.88). Quitters had the lowest risk of all cancers (aHR, 0.94; 95% CI, 0.92-0.96), smoking-related cancers (aHR, 0.91; 95% CI, 0.89-0.93), and lung cancer (aHR, 0.79; 95% CI, 0.76-0.83). In further analysis with 3 consecutive screenings, additional smoking reduction (from reducers II to reducers I) lowered the risk of lung cancer (aHR, 0.74; 95% CI, 0.58-0.94) in comparison with sustainers. Quitting among reducers I further decreased the risk of all cancers (aHR, 0.90; 95% CI, 0.80-1.00), smoking-related cancers (aHR, 0.81; 95% CI, 0.81-0.92), and lung cancer (aHR, 0.66; 95% CI, 0.52-0.84) in comparison with sustainers. Smoking resumption after quitting, even at a lower level, increased the risk of smoking-related cancers (aHR, 1.19; 95% CI, 1.06-1.33) and lung cancer (aHR, 1.48; 95% CI, 1.21-1.80) in comparison with sustained quitting.
Conclusions
Smoking cessation and, to a lesser extent, smoking reduction decreased the risks of cancer. Smoking resumption increased cancer risks in comparison with sustained quitting.

Currently, South Africa has one of the highest rates of silicosis in the world.

The article discusses the success of the Global Alliance against Chronic Respiratory Diseases (GARD) in Brazil. It details the initiatives launched to address chronic respiratory diseases (CRDs) like asthma and COPD, emphasizing the development of national programs and collaborative efforts with the
...
World Health Organization (WHO). Key achievements include successful advocacy, education campaigns, and pilot projects for asthma control, which have led to improved access to treatment and better management of CRDs. Despite challenges such as limited government priority, GARD Brazil has made significant progress in awareness and care for respiratory conditions. The article highlights the need for continued support to sustain these efforts and develop a formal national action plan.

s diagnoses by three pediatricians who were guided by study definitions that were based on medical history, physical examination findings, laboratory and radiological tests, and response to bronchodilators. Children with asthma or bronchiolitis were categorized as “asthma syndrome”. Using this approach, 253 (41.2%) had asthma syndrome. History of and present breathing difficulties and present cough and wheezing was the best performing combination of four questionnaire items [sensitivity 80.8% (95% CI 77.6–84.0); specificity 84.7% (95% CI 81.8–87.6)]. The screening tool for asthma syndrome in ‘under-fives’ may provide a simple, cheap and quick method of identifying children with possible asthma. The validity and reliability of this tool in primary care settings should be tested.

Demographic and epidemiological transitions are changing the age structure of the population and the most common diseases. Non-communicable respiratory diseases are an increasing problem at both ends of the age range in low-income and middle-income countries. In children,
...
who represent a large proportion of the total population, the increasing problem of asthma is a strain on health services. Improved survival of the older population is increasing the proportion of morbidity and mortality attributable to chronic lung diseases. Health services in low-resource countries are poorly adapted to treating chronic diseases. Designed to respond episodically to acute disease, almost all historical investment has focused on infectious diseases. Crucial to the successful management of chronic diseases is an infrastructure designed to support pro-active management, providing not only an accurate diagnosis, but also a secure supply of cost effective drugs at an affordable price. The absence of such an infrastructure in many countries and the market failure that makes drugs generally more expensive in low-resource regions means that many people with chronic non-communicable lung diseases are not given effective treatment. This has damaging economic consequences. The common causes of poor lung health in lowincome countries are not the same as those in richer countries, and there is a need to study why they are so common and how best to manage them.

The IFRC Psychosocial Centre has published a guidance note providing an overview of the psychosocial consequences of virus outbreaks, with a focus on mpox, and outlines key considerations for MHPSS programming.
The current mpox outbreaks present numerous challenges for responding National Societi

es. A key issue is addressing stigma as individuals infected, or suspected of having mpox may experience social ostracization, discrimination, and even violence. In many African communities, where cultural and social norms are vital to community health, considering the cultural and psychosocial implications of virus outbreaks is integral for effective disease management. In addition, Red Cross Red Crescent staff and volunteers may be personally exposed and working in complex environments with rumours and misinformation generating fear and anxiety. This guidance addresses the key mental health and psychosocial support implications of the ongoing mpox crisis.
Guleed Dualeh, MHPSS Advisor
This guidance note is intended for Red Cross Red Crescent National Societies and IFRC departments who may be responding to mpox in their country, or region. It includes guidance on:
Common reactions and behaviours in epidemics
Caring for staff and volunteers in health emergencies
Integration of MHPSS considerations for into health responses

Healthy Settings, a key component of Malawi’s Health Sector Strategic Plan (HSSP) 2011–2016, is the World Health Organization’s (WHO) holistic community-led approach to achieving health improvement by addressing social determinants of health,
...
an approach which is central to the current WHO framework on integrated people-centred health services. Healthy Settings projects by their construct have many different components which vary from one group and community to another depending on their priorities: from housing, hospital improvements and waste management to “softer” interventions like leadership skills training and health promotion. It can be challenging to find relevant indicators to monitor and assess the impact of such a complex holistic project, this paper explores if social capital data can provide useful impact assessment indicators at the start of such a project.
