Community-based strategies play a significant role in many health systems in low- and middle-income countries, especially in light of critical shortages in the health workforce. The term community health worker has been used to refer to volunteers and salaried, professional or lay health workers wit...h a wide range of training, experience, scope of practice and integration in health systems. In the context of this study, we use the term community-based practitioner (CBPs) to reflect the diverse nature of these cadres of health workers.
CBPs provide preventive, promotive, curative and palliative services across a range of areas, including reproductive, maternal, newborn and child health, HIV, tuberculosis, malaria, control of other endemic diseases, and noncommunicable diseases. Significant evidence has emerged over the past two decades on their effectiveness, which has triggered interest in the potential to use their services to expand access to care, in particular in rural and underserved areas where deployment and retention of more qualified health workers is problematic. Calls have been made to integrate CBP programmes in human resources and health strategies, and to scale up rapidly the extent and coverage of CBP initiatives.

Cardiovascular disease is a major cause of disability and premature death throughout the world, and contributes substantially to the escalating costs of health care. The underlying pathology is atherosclerosis, which develops over many years and is usually advanced by the time symptoms occur, genera...lly in middle age. Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modification of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease.
This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. They have been addressed in previous WHO guidelines.
Several forms of therapy can prevent coronary, cerebral and peripheral vascular events. Decisions about whether to initiate specific preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord-
ing to simple predictions of absolute cardiovascular risk.
Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances.

Health systems the world over have embraced the value of community health workers (CHWs) in extending essential services to the community level, improving health equity and progressing toward universal health coverage. Governments now have an opportunity to institutionalize CHW programs and professi...onalize this essential cadre of the health workforce. What will it take to ensure CHW programs, at scale, can achieve their full potential?
Fortunately, policymakers, funders, NGOs, and other partners seeking to design, revamp, or strengthen CHW programs have a suite of tools at their disposal. One of the longest-standing and most rigorously field-tested of these tools is the Community Health Worker Assessment and Improvement Matrix (CHW AIM), an assessment tool which can be used to design, evaluate and strengthen CHW programs.
You can find this assessment tool on this page here. The matrix is also downloaded on MEDBOX, but if you want, you can register for free and get the matrix. After that follow the points underneath.

Spirometry is required as part of the comprehensive evaluation of both adult and paediatric individuals with suspected or confirmed respiratory diseases and occupational assessments. It is used in the categorisation of impairment, grading of severity, assessment of potential progression and response... to interventions. Guidelines for spirometry in South Africa are required to improve the quality, standardisation and usefulness in local respiratory practice. The broad principles of spirometry have remained largely unchanged from previous versions of the South African Spirometry Guidelines; however, minor adjustments have been incorporated from more comprehensive international guidelines, including adoption of the Global Lung Function Initiative 2012 (GLI 2012) spirometry reference equations for the South African population.
All equipment should have proof of validation regarding resolution and consistency of the system. Daily calibration must be performed, and equipment quality control processes adhered to. It is important to have standard operating procedures to ensure consistency and quality and, additionally, strict infection control as highlighted during the COVID-19 pandemic.
Adequate spirometry relies on a competent, trained operator, accurate equipment, standardised operating procedures, quality control and patient co-operation. All manoeuvres must be performed strictly according to guidelines, and strict quality assurance methods should be in place, including acceptability criteria (for any given effort) and repeatability (between efforts).

Our aim is to review current asthma epidemiology, achievements from the last 10 years, and persistent challenges of asthma man- agement and control in low-middle income countries (LMICs). Despite global efforts, asthma continues to be an important public health problem worldwide, particularly in poo...rly resourced settings. Several epidemiological studies in the last decades have shown significant variability in the prevalence of asthma globally, but generally a marked increase in LMICs resulting in significant mor- bidity and mortality. Poverty, air pollution, climate change, exposure to indoor allergens, urbanization and diet are some of the factors that contribute to inadequate control and poor outcomes in developing countries. Although asthma guidelines have been developed to raise awareness and improve asthma diagnosis and treatment, problems with underdiagnosis and undertreatment are still common. In addition, important social, financial, cultural and healthcare barriers are common obstacles in LMICs in achieving control. Given the high burden of asthma in these countries, adaptation and implementation of national asthma guidelines tailored to local needs should be a public health priority. Governmental commitment, education, better health system infrastructure, access to care and effective asthma medications are the cornerstone of achieving success.

Asthma is the most common chronic disease in children globally. The Global Asthma Network (GAN) Phase I study aimed to determine if the worldwide burden of asthma symptoms is changing.
This updated cross-sectional study used the same methods as the International study of Asthma and Allergies in Chi...ldhood (ISAAC) Phase III. Asthma symptoms were assessed from centres that completed GAN Phase I and ISAAC Phase I (1993–95), ISAAC Phase III (2001–03), or both. We included individuals from two age groups (children aged 6–7 years and adolescents aged 13–14 years) who self-completed written questionnaires at school. We estimated the 10-year rate of change in prevalence of current wheeze, severe asthma symptoms, ever having asthma, exercise wheeze, and night cough (defined by core questions in the questionnaire) for each centre, and we estimated trends across world regions and income levels using mixed-effects linear regression models with region and country income level as confounders.
Overall, 119 795 participants from 27 centres in 14 countries were included: 74 361 adolescents (response rate 90%) and 45 434 children (response rate 79%). About one in ten individuals of both age groups had wheeze in the preceding year, of whom almost half had severe symptoms. Most centres showed a change in prevalence of 2 SE or more between ISAAC Phase III to GAN Phase I. Over the 27-year period (1993–2020), adolescents showed a significant decrease in percentage point prevalence per decade in severe asthma symptoms (–0·37, 95% CI –0·69 to –0·04) and an increase in ever having asthma (1·25, 0·67 to 1·83) and night cough (4·25, 3·06 to 5·44), which was also found in children (3·21, 1·80 to 4·62). The prevalence of current wheeze decreased in low-income countries (–1·37, –2·47 to –0·27], in children and –1·67, –2·70 to –0·64, in adolescents) and increased in lower-middle-income countries (1·99, 0·33 to 3·66, in children and 1·69, 0·13 to 3·25, in adolescents), but it was stable in upper-middle-income and high-income countries.
Trends in prevalence and severity of asthma symptoms over the past three decades varied by age group, country income, region, and centre. The high worldwide burden of severe asthma symptoms would be mitigated by enabling access to effective therapies for asthma.

To help parents keep their children healthy and fit, WHO has developed the Child Nutrition and Physical Activity Guide. In addition to parents, the guide may prove to be a useful tool for other adults (such as grandparents or caregivers) working with primary school-aged children.
The Child Nutrit...ion and Physical Activity Guide is published only in the Russian language with support from the Ministry of Health of the Russian Federation for use in Russian-speaking countries. It addresses the urgent need in some countries to improve child nutrition, particularly in areas that face a double health burden characterized by coexistence of undernutrition and overweight, obesity or noncommunicable diseases. Many children in those countries never eat breakfast, and their diet consists of large quantities of sweets and sugar-sweetened beverages with almost no vegetables and fruit.
The WHO guide also offers ideas on how to stimulate children’s interest in physical activity, such as active play, exercise or sports. This is especially relevant for countries of the Commonwealth of Independent States (CIS), where, according to the latest findings, schoolchildren have a low participation in organized sports and exercise. On the other hand, a high proportion of schoolchildren walk to school every day. This could be a good starting point for CIS countries to make physical activity a daily habit that not only improves children’s physical health, but also promotes better mental health and well-being.
The guide aims to ensure that children obtain the knowledge and skills to make healthy food choices, critically evaluate their diet and integrate physical activity into daily life.

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.

Todos los países de la Región de las Américas en los que la malaria es endémica han asumido el reto de eliminar la enfermedad y de poner en marcha medidas para orientar sus programas y estrategias de salud en esa dirección. En este manual se explica cómo ejecutar las medidas con vistas a logra...r la eliminación de la malaria y prevenir su restablecimiento, mediante el aumento de la intensidad y la calidad de las medidas, la reorientación de las iniciativas, la reducción de los retrasos que favorecen la transmisión y un monitoreo adecuado que permita ajustar las intervenciones. En este sentido, se propone como primer paso estratificar el territorio —de modo que se puedan planificar y priorizar las intervenciones y grupos de población— para, a continuación, aplicar una medida de diagnóstico, tratamiento, investigación y respuesta como estrategia clave dirigida a hacer efectiva la eliminación de la enfermedad y a prevenir su restablecimiento en todos los estratos. Además, el documento trata de hacer operativo el concepto de vigilancia, como intervención promovida por la Organización Mundial de la Salud a través de la Estrategia Técnica Mundial contra la Malaria 2016-2030, y destaca la importancia de que las comunidades tengan acceso al diagnóstico y el tratamiento tempranos. Por último, en el manual también se incluyen aspectos de gestión y monitoreo que deben tenerse en cuenta para la eliminación de los focos de transmisión.

The document "Combating False Information on Vaccines: A Guide for Health Workers" is designed to help health workers address vaccine misinformation. It begins by defining misinformation and explaining why it spreads rapidly, often due to its emotional appeal and simplistic explanations. The guide i...dentifies common sources of vaccine misinformation, including influential individuals who profit from spreading false information. The document outlines strategies for combating misinformation, emphasizing the importance of health workers as trusted sources. It provides tips for identifying misinformation online, such as checking URLs, dates, and author credentials, and recognizing tactics like evoking strong emotions or pushing conspiracy theories. Two main approaches to fighting misinformation are discussed: prebunking and debunking. Prebunking involves warning individuals about potential misinformation before they encounter it, while debunking aims to correct false information after it has been consumed. The guide offers practical examples for both methods. Additionally, the document highlights the role of health workers in supporting peers and patients to trust immunization. It suggests being kind, nonjudgmental, and transparent when addressing concerns, and using motivational interviewing techniques to understand and respond to patients' doubts. Overall, the guide emphasizes the critical role of health workers in maintaining trust in vaccines and provides comprehensive strategies to identify, address, and prevent the spread of vaccine misinformation in clinical and community settings. The guide is a valuable resource for health workers to enhance their ability to combat vaccine misinformation, support informed decision-making, and promote trust in vaccines within their communities, and it addresses a pressing issue with practical solutions, supports trusted health workers, and ultimately aims to protect public health by promoting accurate information and trust in vaccines.
