The World Heart Federation (WHF) has been advocating globally for stronger
legislation and policy regarding cardiovascular disease (CVD) for many years. Now, as focus shifts from global to national progress, we call on members and colleagues to advocate for greater action on CVD in your local setti...ngs. This ‘Road to 2018 Toolkit’ provides World Heart Federation members with information
and specific, practical tools to support national CVD advocacy, especially around the United Nations High-Level Meeting on NCDs in 2018.

Heart failure with a reduced ejection fraction (HFrEF) is a condition frequently encountered by healthcare professionals and, in order to achieve the best outcomes for patients, needs to be managed optimally. This guideline document is based on the European Society of Cardiology Guidelines for the t...reatment of acute and chronic heart failure published in 2016, and summarises what is considered the best current management of patients with the condition. It provides information on the definition, diagnosis and epidemiology of HFrEF in the African context. The best evidence-based treatments for HFrEF are discussed, including established therapies (beta-blockers, ACE-i/ARBs, mineralocorticoid receptor antagonists (MRAs), diuretics) that form the cornerstone of heart failure management as well as therapies that have only recently entered clinical use (angiotensin receptor-neprilysin inhibitor (ARNI), sodium/glucose cotransporter-2 (SGLT2) inhibitors). Guidance is offered in terms of more invasive therapies (revascularisation, implantable cardioverter defibrillators (ICDs) and cardiac resynchronisation therapy (CRT) by implantation of a biventricular pacemaker with (CRT-D) or without (CRT-P) an ICD, left ventricular assist device (LVAD) use and heart transplantation) in order to ensure efficient use of these expensive treatment modalities in a resourcelimited environment. Furthermore, additional therapies (digoxin, hydralazine and nitrates, ivabradine, iron supplementation) are discussed and advice is provided on general preventive strategies (vaccinations). Sections to discuss conditions that are particularly prevalent in sub-Saharan Africa (HIV-associated cardiomyopathy (CMO), peripartum CMO, rheumatic heart disease, atrial fibrillation) have been added to further improve clinical care for these commonly encountered disease processes.

Atherosclerotic lower-extremity peripheral artery disease (PAD) is increasingly recognized as an important cause of cardiovascular morbidity and mortality that affects more than 230 million people worldwide. Traditional cardiovascular risk factors, including advanced age, smoking, and diabetes, are ...strongly linked to an increase risk of PAD. Although PAD has been historically underappreciated compared to coronary artery disease and stroke, greater attention on PAD in recent years has led to important new epidemiologic insights in the areas of thrombosis, inflammation, dyslipidemia, and microvascular disease. In addition, the concept of polyvascular disease, or clinically-evident atherosclerosis in multiple arterial beds, is increasingly identified as a particularly malignant cardiovascular disease worthy of special clinical attention and further study. It is noteworthy that PAD may increase the risk of adverse outcomes in similar or even greater magnitude than coronary disease or stroke. In this review, we highlight important new advances in the epidemiology of PAD with a particular focus on polyvascular disease, emerging biomarkers, and differential risk pathways for PAD compared to other atherosclerotic diseases.

Objectives Our study aimed to systematically review the literature and synthesise findings on potential associations of built environment characteristics with type 2 diabetes (T2D) in Asia.
This guide helps pharmacists to understand their role in the hypertension program. From maintaining hypertensive drug stock, to drug dispensing, to recording and reporting, to awareness generation with patients.
Patients with diabetes are at increased risk of developing cardiovascular disease (CVD) with its manifestations of coronary artery disease (CAD), heart failure (HF), atrial fibrillation (AF), and stroke, as well as aortic and peripheral artery diseases. In addition, diabetes is a major risk factor f...or developing chronic kidney disease (CKD), which in itself is associated with developing CVD. The combination of diabetes with these cardio-renal comorbidities enhances the risk not only for cardiovascular (CV) events but also for CV and all-cause mortality. The current European Society of Cardiology (ESC) Guidelines on the management of cardiovascular disease in patients with diabetes are designed to guide prevention and management of the manifestations of CVD in patients with diabetes based on data published until end of January 2023. Over the last decade, the results of various large cardiovascular outcome trials (CVOTs) in patients with diabetes at high CV risk with novel glucose- lowering agents, such as sodium–glucose co-transporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs), but also novel non-steroidal mineralocorticoid receptor antagonists (MRAs), such as finerenone have substantially expanded available therapeutic op-
tions, leading to numerous evidence-based recommendations for the management of this patient population.

sthma prevalence is increasing worldwide, and surveys indicate that most patients in developed and developing countries, including South Africa, do not receive optimal care and are therefore not well controlled. Standard management guidelines adapted to in-country realities are important to support ...optimal care. The South African Thoracic Society (SATS) first published a guideline for the management of chronic persistent asthma in 1992, which has subsequently been revised several times.
The main aim of the present document was to revise and update SATS’ statement on the suggested management of chronic asthma, based on the need to promote optimal care and control of asthma, together with the incorporation of new concepts and drug developments. This revised document reinforces optimal care and incorporates the following primary objectives to achieve the recent advances in asthma care:
• continued emphasis on the use of inhaled corticosteroids (ICS) as the foundation of asthma treatment
• to reduce the reliance on short-acting beta-2 agonist (SABA) monotherapy for asthma symptoms
• to incorporate the evidence and strategy for the use of the combination of an ICS and formoterol for acute symptom relief (instead of a SABA)
• to incorporate the evidence and strategy for the use of as-needed ICS-long-acting beta agonists (LABA) for patients with infrequent symptoms or ‘mild’ asthma
• to incorporate the evidence and strategy for the use of a long-acting muscarinic antagonist (LAMA) in combination with ICS-LABA; and
• to incorporate the evidence and strategy for the use of and management with a biologic therapy in severe asthma.

Asthma is the most common chronic respiratory disease among school-going adolescents worldwide. However, the burden of severe asthma is highest in Sub-Saharan Africa. This study aimed to explore teachers’ perceptions of asthma care across six African countries. We conducted focus group discussions... (FGDs) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. FGDs were conducted in Kumasi(Ghana), Blantyre (Malawi), Lagos (Nigeria), Durban (South Africa), Kampala (Uganda), and Harare (Zimbabwe) between 01 November 2020 and 30 June 2021. We identified two key themes related to asthma care; barriers to asthma care and suggestions to improve the care of adolescents with asthma. Barriers reported by teachers included a lack of knowledge and skills among themselves, adolescents, and caregivers. In addition, some traditional beliefs of teachers on asthma exacerbated challenges with asthma care in schools. Regarding suggestions, most teachers identified a need for all-inclusive asthma training programmes for teachers, adolescents and caregivers, focusing on acute episodes and mitigating triggers. Utilising teachers with personal experiences with asthma to advocate and support these initiatives was suggested. Further suggestions included the need for annual screening to enable early identification of adolescents with asthma and clarify restrictions on teachers administering asthma medications. Teachers across African schools identify multiple barriers to asthma care. Structured school education programs and annual asthma screening are key to addressing some barriers to care.

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.

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.

Several challenges face asthma management in Egypt, including the high percentage of uncontrolled patients, inadequate compliance, and overuse of short-acting beta-agonists (SABAs) leading to increased asthma-related morbidity and mortality. In this regard, the recent Global Initiative for Asthma (G...INA) recommendations included inhaled corticosteroids containing therapy for mild asthma. Local healthcare systems and healthcare professionals (HCPs) often experience practical challenges when implementing global guidelines.

Asthma is the commonest chronic childhood disease and encompasses a spectrum of airway diseases with similar symptoms. Inaccurate diagnosis remains common, especially in younger children, with failure to characterize the different “asthmas.” Children worldwide repeatedly suffer symptoms which se...verely affect their everyday lives. Children die from asthma, especially in low and middle-income countries (LMICs). In many countries, asthma prevalence is rising. Access to effective care and changing environments are hugely variable and may explain the higher morbidity in inner-city children, in LMICs, and in deprived populations in high-income countries. Despite the disease being eminently controllable, morbidity and mortality persist.

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.
