This document provides detailed guidance on laboratory testing for suspected diphtheria cases during significant outbreaks or in low-resource settings. It aims to supplement and build on other existing WHO guidance documents on surveillance standards, diagnostics and research on Corynebacterium by p...roviding key considerations for laboratories that allow the rationalization and optimization of testing during outbreaks. The recommendations given here have been prepared by WHO in consultation with, and reviewed by, global experts with experience in laboratory analysis of Corynebacterium species and in outbreak settings, or with expertise in developing new technologies for diphtheria research and diagnosis. Unless otherwise stated, the considerations provided apply to diphtheria outbreaks caused by toxin-producing C. diphtheriae with a classical respiratory diphtheria presentation.

This study compared clinical and autopsy findings for three asbestos-related diseases (asbestosis, mesothelioma and lung cancer) in former asbestos mineworkers, and explored factors that influenced agreement between clinical and autopsy findings using data from two compensation systems. In South Afr...ica, statutory compensation for occupational lung diseases in mineworkers makes provisions for autopsy examinations of the cardio-respiratory organs at the National Institute for Occupational Health (NIOH) in Johannesburg. In addition, the Johannesburg-based Asbestos Relief Trust and Kgalagadi Relief Trust (the “Trusts”) compensate individuals with defined asbestos-related diseases who worked in or lived near qualifying asbestos mining or processing operations. The Trusts also compensate dependents of deceased qualifying mineworkers and therefore encourage statutory autopsies for the detection of previously undiagnosed asbestos-related disease or disease that may have progressed to higher compensation grades.

The pamphlet "Marijuana" explains the effects and risks of cannabis use. It describes THC, the psychoactive compound in cannabis, which binds to cannabinoid receptors in the brain, causing effects like relaxation, altered perception, and euphoria. Short-term effects include red eyes, hunger, and anx...iety, while long-term effects may involve memory loss, lung problems, and slowed brain development, especially with early and frequent use. It highlights the potential for negative impacts on mental and physical health while noting there are no direct deaths solely from marijuana use. The pamphlet provides links to resources for further information and recovery options.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

The book has three main parts. The first part describes research in Viet Nam conducted on medicinal plants in line with the national policy of developing a system of medicine and pharmacy that integrates the modern and traditional systems. Th...e second part, which constitutes the core of the book, describes and illustrates the 200 most valuable species of wild and cultivated medicinal plants in Viet Nam. Each plant species is first documented by a full colour drawing illustrating the plant's distinctive features and natural colours. Explanatory notes for each species provide a concise description of the plant and give local names, flowering period, geographical distribution, parts used, chemical composition, and therapeutic uses. Information on indications and dosage is also provided.
To facilitate retrieval of information, the third part indexes plant species according to botanical name, Vietnamese name, and English name.

Facing the global nutrition challenges, the World Health Organization (WHO) teamed up with the United Nations Institute for Training and Research (UNITAR) to design, under the guidance of the Department of Nutrition for Health and Development (NHD), a Nutrition Knowledge Hub. By building the techni...cal and functional capacities of all relevant staff at WHO through e-learning courses and key nutrition-related training and knowledge materials, the Nutrition Knowledge Hub aims to contribute to the acceleration and increase of the nutrition impact at the country level. The Nutrition Knowledge Hub also offers free and open courses to reach a larger public and raise awareness on the malnutrition problem and WHO’s response.

In 1988, the Centre for Research on the Epidemiology of Disasters (CRED) launched the Emergency Events Database (EM-DAT). EM-DAT was created with the initial support of the World Health Organisation (WHO) and the Belgian Government.
The main objective of the database is to serve the purposes of h...umanitarian action at national and international levels. The initiative aims to rationalise decision making for disaster preparedness, as well as provide an objective base for vulnerability assessment and priority setting.
EM-DAT contains essential core data on the occurrence and effects of over 22,000 mass disasters in the world from 1900 to the present day. The database is compiled from various sources, including UN agencies, non-governmental organisations, insurance companies, research institutes and press agencies.

The article "Asthma in South African adolescents: a time trend and risk factor analysis over two decades" investigates the prevalence and risk factors for asthma in Cape Town adolescents from 2002 to 2017. The study finds that while the overall prevalence of asthma remained similar, the severity of ...the condition increased significantly. Risk factors for asthma and severe cases include smoking, pet exposure, outdoor pollution, and living in informal housing. Despite these trends, underdiagnosis remains a concern, as only one-third of adolescents with current or severe asthma had been formally diagnosed. The article emphasizes the need for better public health strategies to address environmental exposures and improve asthma diagnosis and treatment.

The article "The burden of chronic obstructive pulmonary disease and its attributable risk factors in the Middle East and North Africa region, 1990–2019" provides an analysis of the prevalence, mortality, and disability-adjusted life-years (DALYs) due to COPD in the MENA region from 1990 to 2019. ...The study uses data from the Global Burden of Disease (GBD) 2019 and shows that while age-standardized death and DALY rates have decreased over 30 years, COPD remains a significant health issue, especially among older populations. The main risk factors identified are smoking, ambient particulate pollution, and occupational exposure. The research underscores the impact of socioeconomic factors and recommends targeted public health initiatives to reduce the burden.
