Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

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.

This booklet provides an overview of all findings from the Global Burden of Disease 2017 study. Published in The Lancet in November 2018, GBD 2017 provides for the first time an independent estimation of population, for each of 195 countries and territories and the globe, using a standardized, repli...cable approach, as well as a comprehensive update on fertility. Produced with the input of 3,676 collaborators from 146 countries and territories, GBD 2017 incorporates major data additions and improvements, and methodological refinements. GBD 2017 also includes estimates at the subnational level for selected locations.

The aim of these Guidelines is to provide a framework for the conservation and sustainable use of plants in medicine. To do this, the Guidelines describe the various tasks that should be carried out to ensure that where medicinal plants are taken from the wild, they are taken on a basis that is sust...ainable.
The Guidelines conform to the principles of Caring for the Earth, prepared in partnership by IUCN, UNEP and WWF. Caring for the Earth extends the message and scope of the World Conservation Strategy to an ethic of sustainable living, and explains how to integrate conservation with development. Its message is particularly relevant to the issue of medicinal plants, which in many parts of the world are being seriously depleted due to over-exploitation and loss of habitats, resulting in a lack of essential medicines and so reducing options for the future.

The five hepatitis viruses have different epidemiological profiles, and their impact, duration, and transmission route also vary. The most common transmission routes contributing to the spread of hepatitis are exposure to infected blood via blood transfusion or unsafe injection practices, consumptio...n of contaminated food and drinking water, and transmission from mother to child during pregnancy and delivery. Also, unsafe injection practices, including the use of unsterile needles and syringes, serve as a major pathway for the spread of hepatitis B and C, and reducing transmission of both diseases requires addressing these practices.
