The South African (SA) guidelines for cardiac patients for non-cardiac surgery were developed to address the need for cardiac risk assessment and risk stratification for elective non-cardiac surgical patients in SA, and more broadly in Africa.
The guidelines were developed by updating the Canadian ...Cardiovascular Society Guidelines on Perioperative Cardiac Risk Assessment
and Management for Patients Who Undergo Non-cardiac Surgery, with a search of literature from African countries and recent publications. The updated proposed guidelines were then evaluated in a Delphi consensus process by SA anaesthesia and vascular surgical experts.
The recommendations in these guidelines are:
1. We suggest that elective non-cardiac surgical patients who are 45 years and older with either a history of coronary artery disease, congestive cardiac failure, stroke or transient ischaemic attack, or vascular surgical patients 18 years or older with peripheral vascular disease require further preoperative risk stratification as their predicted 30-day major adverse cardiac event (MACE) risk exceeds 5%
(conditional recommendation: moderate-quality evidence).
2. We do not recommend routine non-invasive testing for cardiovascular risk stratification prior to elective non-cardiac surgery in adults (strong recommendation: low-to-moderate-quality evidence).
3. We recommend that elective non-cardiac surgical patients who are 45 years and older with a history of coronary artery disease, or stroke or transient ischaemic attack, or congestive cardiac failure or vascular surgical patients 18 years or older with peripheral vascular disease should have preoperative natriuretic peptide (NP) screening (strong recommendation: high-quality evidence).
4. We recommend daily postoperative troponin measurements for 48 - 72 hours for non-cardiac surgical patients who are 45 years and older with a history of coronary artery disease, or stroke or transient ischaemic attack, or congestive cardiac failure or vascular surgical patients 18 years or older with peripheral vascular disease, i.e. (i) a baseline risk >5% for MACE 30 days after elective surgery (if no preoperative NP screening), or (ii) an elevated B-type natriuretic peptide (BNP)/N-terminal-prohormone B-type natriuretic peptide (NT-proBNP) measurement before elective surgery (defined as BNP >99 pg/mL or a NT-proBNP >300 pg/mL) (conditional recommendation: moderate-quality evidence).
Additional recommendations are given for the management of myocardial injury after non-cardiac surgery (MINS) and medications for comorbidities.

Air pollution from road traffic is a serious health hazard, and people with preexisting respiratory disease may be at increased risk. We investigated the effects of short-term exposure to diesel traffic in people with asthma in an urban, roadside environment.
This document updates the ARIA sections on the links between rhinitis and asthma. Relevant publications between January 2000 and December 2005 were included. Complementary and alternative medicine is not evaluated in this document since it has been published separately. Likewise, an update on pharma...cological therapy of AR was published separately. Therefore, in the therapeutical component of the current review we decided to focus on aspects related to concomitant rhinitis and asthma.
The aim of this review was to present new evidence related to major ARIA statements, either to support or to refute them, by bringing the most recent information in the context of the previous knowledge on this subject. Additionally, we looked for information that could potentially lead to novel statements.

The Asthma Control Questionnaire (ACQ) was developed to measure the primary goals of asthma management as identified by international guidelines. All guidelines indicate that to achieve good control, treatment should minimise day- and night-time symptoms, activity limitation, airway narrowing and re...scue bronchodilator use and thus reduce the risk of life-threatening exacerbations and long-term morbidity. Three independent studies have provided evidence that the ACQ is valid for measuring asthma control and has strong measurement properties for use both in clinical practice and research. In addition, the smallest change in score that can be considered clinically important has been determined.

The Asthma Control Questionnaire (ACQ)1 was developed and validated to measure the primary clinical goal of asthma management as identified by international guidelines. They indicate that to achieve good control, treatment should minimise day and night time symptoms, activity limitation, airway narr...owing and rescue bronchodilator use and thus reduce the risk of life-threatening exacerbations and long-term morbidity. The importance of including all aspects of control in the assessment of individual patients was emphasised by a recent factor analysis which showed that clinical asthma is composed of distinct components which are not closely correlated with each other.6 However, in some studies it may not be possible to collect airway calibre or short-acting β2-agonists data. Previous analysis of non-clinical trial data suggested that when ACQ scores are analysed as group data, the heterogeneity of the way in which individual patients present with inadequate control is lost in the estimation of the mean and the need to measure each individual component of asthma control may become unnecessary. In this analysis, ACQ data from a clinical trial was used to evaluate the measurement properties (reliability, responsiveness, validity and interpretability), of three shortened versions of the ACQ. In addition, we have examined whether the precision and accuracy of estimating the effect of the intervention on asthma control was maintained when the two questions concerning airway calibre and short-acting β2-agonists use were omitted from the trial analysis.

Asthma guidelines indicate that the goal of treatment should be optimum asthma control. In a busy clinic practice with limited time and resources, there is need for a simple method for assessing asthma control with or without lung function testing.
It is estimated that as many as 300 million people of all ages, and all ethnic backgrounds, suffer from asthma and the burden of this disease to governments, health care systems, families, and patients is increasing worldwide. In 1989 the Global Initiative for Asthma (GINA) program was initiated in ...an effort to raise awareness among public health and government officials, health care workers, and the general public that asthma was on the increase. The GINA program recommends a management program based on the best available scientific evidence to provide effective medical care for asthma tailored to local health care systems and resources.

Several countries or regions within countries have an effective national asthma strategy resulting in a reduction of the large burden of asthma to individuals and society. There has been no systematic appraisal of the extent of national asthma strategies in the world.
The 2023 update of the Global Strategy for Asthma Management and Prevention incorporates new scientific information about asthma based on a review of recent scientific literature by an international panel of experts on the GINA Science Committee. This comprehensive and practical resource about one o...f the most common chronic lung diseases worldwide contains extensive citations from the scientific literature and forms the basis for other GINA documents and programs.

Asthma is chronic inflammation of the airways in the lungs.
In asthma, the airways in the lung narrow due to swelling of
the mucosa, increased mucus production, and spasm of the airways.
Aerosol pollutants are known to raise the risk of development of non-communicable respiratory diseases (NCRDs) such as asthma, chronic bronchitis, chronic obstructive pulmonary disease, and allergic rhinitis. Sub-Saharan Africa’s rapid pace of urbanization, economic expansion, and population growt...h raise concerns of increasing incidence of NCRDs. This research characterizes the state of research on pollution and NCRDs in the 46 countries of Sub-Saharan Africa (SSA). This research systematically reviewed the literature on studies of asthma; chronic bronchitis; allergic rhinitis; and air pollutants such as particulate matter, ozone, NOx, and sulfuric oxide.

South Africa has possibly the highest incidence of malignant mesothelioma anywhere, thanks to more than a century of mining asbestos in the Northern Cape, North- West, Limpopo and Mpumulanga provinces. There are three types of asbestos and all were mined in South Africa; the most carcinogenic is cro...cidolite, of which production peaked in 1977. The last asbestos mine closed only in 2002, and massive environmental contamination from unrehabilitated mines and mine dumps will ensure ongoing exposure well into the future.

Asthma is the most common chronic condition in children worldwide. It affects daytime activities, sleep and school attendance and causes anxiety to parents, families and other carers. The quality of asthma diagnosis and management globally still needs substantial improvement. From infancy to the tee...nage years, there are age-specific challenges, including both underdiagnosis and overdiagnosis with stigma-related barriers to treatment in some cultures and in adolescents. The Paediatric Asthma Project Plan has been initiated to strengthen diagnosis and management of asthma. This encompasses a vision for the next 10–15 years, building on the knowledge and experience from previous educational projects. It will take into account the educational needs of patients, carers and healthcare professionals as well as the accessibility and affordability of medication, particularly in low and middle-income countries where the prevalence of asthma is rising more rapidly. This overview presents a first step for those involved in the diagnosis and management of childhood asthma to strengthen care for children globally.

Coronavirus disease 2019 has a mild disease course in children and adolescents. Chronic respiratory conditions, including asthma, have been suggested as risk factors; however, asthma in children is highly variable in both triggers and severity.
During the pandemic, pediatric asthma services limite...d consultations and established virtual clinics. However, respondents perceived their patients’ asthma control to be retained or even improved, while treatment adherence was considered increased. Children with asthma were not disproportionately affected by coronavirus disease 2019.
Trigger avoidance and treatment adherence can rapidly improve asthma control in children, even under lockdown pressure. Children/adolescents with asthma do not appear to need additional prophylactic measures from coronavirus disease 2019 when asthma is well-treated. This article analyses the effect of COVID-19 on Asthma in children, providing information for management guidelines.
