For patients on NIPPV or HFNO with persistent hypoxaemia or respiratory distress:
• Check the equipment: inspect the exterior of the machine, the tubing (circuit), the mask for any sign of mechanical damage, confirm it fits securely without leak (if CPAP/BiPAP) and the filters are in place. Ensur...e the settings are appropriate and flow is maximized.
• Check the oxygen source: there is sufficient oxygen available and flowing through the device. If FiO2 > 50% of oxygen is needed, the ventilator must have a blender.
• Check there is no obstruction with secretions: patients with COVID-19 may have very thick secretions which may block small and large airways and cause sudden respiratory deterioration.

This report provides an overview of air pollution levels and associated health impacts in cities around the world. Since urban areas are often hotspots for poor air quality, city-level data can help to inform targeted efforts to curb urban air pollution and improve public health. This report draws o...n data from the Global Burden of Disease project and from peer-reviewed analyses led by Susan Anenberg of the George Washington University.

This brief advocacy document highlights the burden, risks and prevention of injuries and violence, which took the lives of 4.4 million people in 2019 and constitute 8% of all deaths. Among the injury-related causes of death include road traffic crashes, drowning, falls, burns, poisoning and violence... against oneself or others. For people age 5-29 years, three of the top five causes of death are injury-related, including road traffic injuries, homicide, and suicide. Injuries and violence are not evenly distributed across or within countries – some people are more vulnerable than others depending on the conditions in which they are born, grow, work, live and age; in general, being young, male and of low socioeconomic status all increase the risk of injury. This document, aimed at public health professionals; injury prevention researchers, practitioners and advocates; and donors, draws attention to specific strategies based on sound scientific evidence that are effective and cost-effective at preventing injuries and violence; it is critical that these strategies are more widely implemented.

As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

MEASURE Evaluation PRH Working Paper Series
WHO recommends that pre-exposure prophylaxis (PrEP) be offered as an additional prevention choice for HIV-negative individuals at substantial risk of HIV infection as part of combination prevention approaches.
HIV drug resistance has been rarely reported among PrEP users who tested HIV positive i...n randomized controlled trials or open-label studies. However, PrEP-selected HIV drug resistance could potentially negatively impact the effectiveness of treatment options among PrEP users who acquire HIV, since there is a potential for overlapping resistance profiles between antiretroviral drugs used for both PrEP and first-line antiretroviral therapy.

4. Central African Republic
Clashes throughout 2018 in the capital Bangui and a number of major towns illustrate the deadly threat posed by armed groups – a mix of pro-government militias, ex-rebels, bandits and local “self-defence” units – that control much of the countr...y. MINUSCA, the UN peacekeeping force, has failed to neutralise these groups and, as a result, is mistrusted by the general public. Likewise, the national army, slowly being deployed in parts of the country, has been unable to constrain the armed groups’ predatory activities. The humanitarian situation remains dire, with more than one million people internally displaced or fleeing to neighbouring countries and 2.5 million in need of assistance, according to the UN.
