Agricultural ecosystems provide humans with food, forage, bioenergy and pharmaceuticals and are essential to human wellbeing. These systems rely on ecosystem services provided by natural ecosystems, including pollination, b...iological pest control, maintenance of soil structure and fertility, nutrient cycling and hydrological services. Preliminary assessments indicate that the value of these ecosystem services to agriculture is enormous and often underappreciated. Agroecosystems also produce a variety of ecosystem services, such as regulation of soil and water quality, carbon sequestration, support for biodiversity and cultural services. Depending on management practices, agriculture can also be the source of numerous disservices, including loss of wildlife habitat, nutrient runoff, sedimentation of waterways, greenhouse gas emissions, and pesticide poisoning of humans and non-target species. The tradeoffs that may occur between provisioning services and other ecosystem services and disservices should be evaluated in terms of spatial scale, temporal scale and reversibility. As more effective methods for valuing ecosystem services become available, the potential for ‘win–win’ scenarios increases. Under all scenarios, appropriate agricultural management practices are critical to realizing the benefits of ecosystem services and reducing disservices from agricultural activities.

This guideline aims to improve the quality of donations and the management thereof and serve as the basis for policies of the State and other organizations in the giving and receiving of donations of medicines, medical devices and IVDs.
Over the last three or four decades, there has been an enorm...ous increase in scientific knowledge about the mode of action, effects and side effects of medicines, medical devices and IVDs. It is important for all
stakeholders to understand that these products have both benefits and risks, that they have to be used carefully and appropriately and that some can do more harm than good.
There are many different scenarios for the donation of medicines, medical devices and IVDs. Donations may take place in acute emergencies or as part of development aid in non-emergency situations. They may involve donations (i.e. direct or through private voluntary organizations), aid by governments or persons authorized to sell medicines, medical devices and/or IVDs.

Eine Leitlinie “Long-/Post-COVID-Syndrom" für Betroffene, Angehörige, nahestehende und
pflegende Personen, die sich auf eine ärztliche Leitlinie stützt („S1-Leitlinie Long-/Post-COVID“
der AWMF; Registernummer 020 - 027)
Erste Ausgabe September 2021
Die WHO hat mit Hilfe der Delphi-Methode eine klinische Falldefinition für das Post-COVID-19-Syndrom entwickelt, die 12 Domänen umfasst und in allen Bereichen verwendet werden kann. Diese erste Version wurde von Patienten, Forschern und anderen Personen aus allen WHO-Regionen entwickelt, wobei dav...on ausgegangen wird, dass sich die Definition ändern kann, wenn sich neue Erkenntnisse ergeben und sich unser Verständnis der Folgen von COVID-19 weiterentwickelt.
Die Post-COVID-19-Erkrankung tritt bei Personen mit einer wahrscheinlichen oder bestätigten SARS-CoV-2-Infektion in der Anamnese auf, in der Regel drei Monate nach dem Auftreten von COVID-19 mit Symptomen, die mindestens zwei Monate anhalten und nicht durch eine andere Diagnose erklärt werden können. Zu den häufigen Symptomen gehören Müdigkeit, Kurzatmigkeit, kognitive Störungen, aber auch andere Symptome, die sich im Allgemeinen auf das tägliche Leben auswirken. Die Symptome können nach der anfänglichen Genesung von einer akuten COVID-19-Episode neu auftreten oder nach der ersten Erkrankung fortbestehen. Die Symptome können auch schwanken oder im Laufe der Zeit wieder auftreten.

La OMS ha elaborado una definición de caso clínico de la afección posterior a la COVID-19 mediante la metodología Delphi que incluye 12 dominios, disponible para su uso en todos los entornos. Esta primera versión fue elaborada por pacientes, investigadores y otras personas, en representación d...e todas las regiones de la OMS, en el entendimiento de que la definición puede cambiar a medida que surjan nuevas pruebas y siga evolucionando nuestra comprensión de las consecuencias de la COVID-19.
La afección posterior a la COVID-19 se produce en personas con antecedentes de infección probable o confirmada por el CoV-2 del SRAS, normalmente a los 3 meses de la aparición de la COVID-19 con síntomas y que duran al menos 2 meses y no pueden explicarse por un diagnóstico alternativo. Los síntomas más comunes son la fatiga, la dificultad respiratoria y la disfunción cognitiva, pero también otros, y generalmente tienen un impacto en el funcionamiento diario. Los síntomas pueden ser de nueva aparición tras la recuperación inicial de un episodio agudo de COVID-19 o persistir desde la enfermedad inicial. Los síntomas también pueden fluctuar o recaer con el tiempo.

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition...al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

Key questions
What is already known?
Critical illness is common throughout the world and COVID-19 has caused a global surge of critically ill patients.
There are large gaps in the quality of care for critically ill patients, especially in low-staffed and low-resourced settings, and mortal...ity rates are high.
Essential Emergency and Critical Care (EECC) is the effective lifesaving care of low-cost and low-complexity that all critically ill patients should receive in all wards in all hospitals in the world.
What are the new findings?
The clinical processes that comprise EECC and the essential care of critically ill patients with COVID-19 have been specified in a large consensus among clinical experts worldwide.
The resource requirements for hospitals to be ready to provide this care has been described.
What do the new findings imply?
The findings can be used across medical specialties in hospitals worldwide to prioritise and implement essential care for reducing preventable deaths.
Inclusion of the EEEC processes could increase the impact of pandemic preparedness and response programmes and policies for health systems strengthening.
