The impact of maternal mental health problems on infants in high income countries has been identified mostly in terms of psychosocial and emotional development, thanks to the groundbreaking early work of Spitz (2) and of Bowlby (3), who studied the emotional needs of infants and mother-child attachm...ent. Subsequently, a large body of literature, also from HICs, documented the effects of maternal mental health on the child's psychological development (4), intellectual competence(5), psychosocial functioning (6) and rate of psychiatric morbidity (7, 8).

The Global Burden of Disease (GBD) study, a collaborative endeavour of the World
Health Organization (WHO), the World Bank and the Harvard School of Public Health,
drew the attention of the international health community to the burden of neurological
disorders and many other chronic conditions. T...his study found that the burden of neurological
disorders was seriously underestimated by traditional epidemiological and health
statistical methods that take into account only mortality rates but not disability rates. The
GBD study showed that over the years the global health impact of neurological disorders
had been underestimated.

Over the ages, human societies have altered local ecosystems and modified regional climates. Today the human influence has attained a global scale. This reflects the recent rapid increase in population size, energy consumption, intensity of land use, international trade and travel, and other human a...ctivities. These global changes have heightened awareness that the long-term good health of populations depends on the continued stability of biosphere's ecological, physical and socioeconomic systems.
The world's climate system is an integral part of the complex of life-supporting processes. Like other large systems, the global climate system is coming under pressure from human activities.
This book seeks to describe the context and process of global climate change, its actual or likely impacts on health, and how human societies and their governments should respond with particular focus on the health sector.

The number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014.
The global prevalence of diabetes* among adults over 18 years of age has risen from 4.7% in 1980 to 8.5% in 2014.
Diabetes prevalence has been rising more rapidly in middle- and low-income countries.
Dia...betes is a major cause of blindness, kidney failure, heart attacks, stroke and lower limb amputation.
In 2012, an estimated 1.5 million deaths were directly caused by diabetes and another 2.2 million deaths were attributable to high blood glucose.
Almost half of all deaths attributable to high blood glucose occur before the age of 70 years.
WHO projects that diabetes will be the 7th leading cause of death in 2030
Healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use are ways to prevent or delay the onset of type 2 diabetes.
Diabetes can be treated and its consequences avoided or delayed with diet, physical activity, medication and regular screening and treatment for complications.

High blood pressure, or hypertension, is one of the most serious risks factors for death from heart diseases and strokes, responsible for 13% of all deaths globally. In South Africa more than 1 in 3 adults live with high blood pressure and it is responsible for 1 in every 2 strokes and 2 in every 5 ...heart attacks. High blood pressure is known as a 'silent killer' because there are rarely any symptoms or visible signs to warn that blood pressure is high. That is why more than 50% of people with high blood pressure are unaware of their condition. In some cases, typically with very high blood pressure, symptoms such as headaches, visual disturbances, nose bleeds, nausea, vomiting, facial flushing and sleepiness may be experienced. Do not wait for symptoms to appear. High blood pressure becomes more likely with older age, but anyone, no matter their age, gender, fitness level or lifestyle can develop high blood pressure. Blood pressure should be measured at least once every year, so don’t delay!

Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GE...MM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors.
Methods and results
We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including fossil fuel use. Global excess mortality from all ambient air pollution is estimated at 8.8 (7.11–10.41) million/year, with an LLE of 2.9 (2.3–3.5) years, being a factor of two higher than earlier estimates, and exceeding that of tobacco smoking. The global mean mortality rate of about 120 per 100 000 people/year is much exceeded in East Asia (196 per 100 000/year) and Europe (133 per 100 000/year). Without fossil fuel emissions, the global mean life expectancy would increase by 1.1 (0.9–1.2) years and 1.7 (1.4–2.0) years by removing all potentially controllable anthropogenic emissions. Because aeolian dust and wildfire emission control is impracticable, significant LLE is unavoidable.
Conclusion
Ambient air pollution is one of the main global health risks, causing significant excess mortality and LLE, especially through cardiovascular diseases. It causes an LLE that rivals that of tobacco smoking. The global mean LLE from air pollution strongly exceeds that by violence (all forms together), i.e. by an order of magnitude (LLE being 2.9 and 0.3 years, respectively).

The NICE guideline "Hypertension in Adults: Diagnosis and Management" outlines recommendations for diagnosing and managing hypertension in adults over 18, including those with type 2 diabetes. It emphasizes accurate blood pressure measurement, recommending ambulatory or home monitoring to confirm di...agnosis. Cardiovascular risk and target organ damage should be assessed, considering age, lifestyle, and other conditions. Initial treatment focuses on lifestyle changes such as diet, exercise, and smoking cessation, with medication advised for stage 1 hypertension at high cardiovascular risk or stage 2 hypertension. Regular monitoring and treatment adjustments are recommended to maintain target blood pressure levels, with specific guidance for people over 80 and those with additional conditions like diabetes or kidney disease. The guideline aims to reduce risks of heart attack, stroke, and other complications, supporting evidence-based treatment decisions in clinical practice.

Since the Alma Ata Declaration in 1978, community health volunteers (CHVs) have been at the forefront, providing health services, especially to underserved communities, in low-income countries. However, consolidation of CHVs position within formal health systems has proved to be complex and continue...s to challenge countries, as they devise strategies to strengthen primary healthcare. Malawi’s community health strategy, launched in 2017, is a novel attempt to harmonise the multiple health
service structures at the community level and strengthen service delivery through a team-based approach. The core community health team (CHT) consists of health surveillance assistants (HSAs), clinicians, environmental health officers and CHVs. This paper reviews Malawi’s strategy, with particular focus on the interface between HSAs, volunteers in community-based programmes and
the community health team. Our analysis identified key challenges that may impede the strategy’s implementation:
(1) inadequate training, imbalance of skill sets within CHTs and unclear job descriptions for CHVs; (2) proposed community-level interventions require expansion of pre-existing roles for most CHT members; and (3) district authorities may face challenges meeting financial obligations and filling community-level positions. For effective implementation, attention and further deliberation is needed on the appropriate forms of CHV support, CHT composition with possibilities of co-opting trained CHVs
from existing volunteer programmes into CHTs, review of CHT competencies and workload, strengthening coordination and communication across all community actors, and financing mechanisms. Policy support through the development of an addendum to the strategy, outlining opportunities for task-shifting between CHT members, CHVs’ expected duties and interactions with paid CHT personnel is recommended.

Ce rapport inclut des analyses tirées des consultations régionales informelles menées dans la Région africaine, dans les Caraïbes et en Amérique du Nord, dans la Région européenne, dans la Région de la Méditerranée orientale, en Amérique latine ainsi que dans la Région de l’Asie du Su...d-Est, auxquelles s’ajoutent trois rencontres organisées dans la Région du Pacifique occidental. Il analyse les similitudes globales, les nuances régionales et les priorités mises en avant dans les six Régions de l’OMS pour la participation significative des personnes avec une expérience vécue.
Il s’agit du deuxième rapport d’une collection de l’OMS intitulée De l’intention à l’action, qui doit servir à constituer une série de ressources pour renforcer la base de données probantes sur l’impact de la participation significative, qui est pour le moment limitée, et à combler le manque d’approches normalisées pour mettre en oeuvre la participation significative. À cette fin, la collection De l’intention à l’action a été pensée comme plateforme pour que les personnes avec une expérience vécue ainsi que les organisations et institutions à la pointe sur ces questions puissent échanger sur les solutions, les difficultés et les pratiques prometteuses relatives à cet objectif transversal. Elle vise également à fournir des récits et des modèles puissants, ainsi que des données probantes dans la perspective de la quatrième réunion publique de haut niveau des Nations Unies sur les MNT, qui devrait se tenir en 2025, et en vue d’atteindre les objectifs de développement durable (ODD) à l’horizon 2030.

Little is known about asthma control in the rising number of African children who suffer from this condition. The Achieving Control of Asthma in Children in Africa (ACACIA) study is an observational study collecting evidence about paediatric asthma in urban areas of Ghana, Malawi, Nigeria, South Afr...ica, Uganda and Zimbabwe. The primary objectives are: (1) to identify 3000 children aged between 12 years and 14 years with asthma symptoms; and (2) to assess their asthma control, current treatment, knowledge of and attitudes to asthma and barriers to achieving good control. Secondary objective is to develop interventions addressing identified barriers to good symptom control.
Each centre will undertake screening to identify 500 school children with asthma symptoms using questions from the Global Asthma Network’s questionnaire. Children identified to have asthma symptoms will fill in a digital survey, including: Asthma Control Test, questions on medication usage and adherence, medical care, the Brief-Illness Perception questionnaire and environmental factors. Exhaled nitric oxide testing and prebronchodilator and postbronchodilator spirometry will be performed. A subgroup of children will participate in focus group discussions. Results will be analysed using descriptive statistics and comparative analysis. Informed by these results, we will assess the feasibility of potential interventions, including the adaption of a UK-based theatre performance about asthma attitudes and digital solutions to improve asthma management.

There is paucity of data on the burden and specific drivers operative in the pathogenesis of chronic obstructive pulmonary disease (COPD) in the African setting and populations. Lack of awareness and inadequate knowledge on the aetio-pathogenesis of the disease together with inadequate capacity for ...COPD care contributes to preventive and management challenges. Thus, the majority of patients with COPD are misdiagnosed, misclassified and mismanaged or undertreated. With the struggling improvement in the quality of healthcare in Africa, studies conducted over the last 10 years indicates the rising trends in both the risk factors and the burden of COPD. The role of new risk factors such as indoor pollution, infections with human immunodeficiency virus (HIV) and pulmonary tuberculosis (TB), in the pathogenesis of COPD in Africa is increasingly being recognized. This literature review attempts to collect and synthesize information that could be useful in improving COPD care and informing the governments to take appropriate actions for prevention, diagnosis and management of COPD in Africa.
