The purpose of cancer screening tests is to detect pre-cancer or early-stage cancer in asymptomatic individuals so that timely diagnosis and early treatment can be offered, where this treatment can lead to better outcomes for some people.
The aim of a cancer screening programme is either to reduc...e mortality and morbidity in a population by early detection and early treatment of a cancer (for example, breast screening) or to reduce the incidence of a cancer by identifying and treating its precursors (such as cervical and colorectal screening).
This short guide is designed to be a quick reference that contains the important ideas about cancer screening. Readers should refer to other publications for comprehensive discussion and detailed guidance on cancer screening programmes.

A rapid evidence briefing. Vaccinated people are less likely to develop long COVID, even if they get infected, a rapid review of 15 studies by the UK Health Security Agency shows.
Supportive supervision is considered critical to community health worker programme performance, but there is relatively little understanding of how it can be sustainably done at scale. Supportive supervision is a holistic concept that encompasses three key functions: management (ensuring performance...), education (promoting development) and support (responding to needs and problems). Drawing on the experiences of the ward-based outreach team (WBOT) strategy, South Africa’s national community health worker (CHW) programme, this paper explores and describes approaches to supportive supervision in policy and programme guidelines and how these are implemented in supervision practices in the North West Province, an early adopter of the WBOT strategy. Outreach teams typically consist of six CHWs plus a nurse outreach team leader (OTL).

CONCLUSIONS: The roles performed by CHWs are broad, varied and essential for diabetes and hypertension management. However, basic knowledge about diabetes and hypertension remains poor while training is unstandardised and haphazard. These need to be improved if community-based NCD management is to b...e successful. The potential of peer education as a complementary mechanism to formal training needs as well as support and supervision in the workplace requires further assessment

Community health workers (CHWs) enable marginalised communities, often experiencing structural poverty, to access healthcare. Trust, important in all patient–provider relationships, is difficult to build in such
communities, particularly when stigma associated with HIV/AIDS, tuberculosis and now ...COVID-19, is widespread.
CHWs, responsible for bringing people back into care, must repair trust. In South Africa, where a national CHW programme is being rolled out, marginalised communities have high levels of unemployment, domestic violence and injury. In this complex social environment, we explored CHW workplace trust, interpersonal trust between the patient and CHW, and the institutional trust patients place in the health system

The threats posed by climate change to agriculture are now well known. Climate change has already resulted in a negative trend in mean crop yield per decade, and this is likely to continue as the century unfolds. In Africa, 650 million people are currently dependent on rain- fed agriculture and, des...pite progress in the Millennium Development Goals, food and nutrition insecurity remainunacceptably high.

The emergence and transmission of zoonotic diseases are driven by complex interactions
between health, environmental, and socio-political systems. Human movement is considered
a significant and increasing factor in these processes, yet forced migration remains an
understudied area of zoonotic res...earch–due in part to the complexity of conducting interdisciplinary
research in these settings.

There is little doubt that 2019 was a defining year on many fronts for the environment. The repercussions of the climate emergency were experienced across the globe, with floods, devastating wildfires, and unprecedented melting of polar ice sheets and glaciers. While the new decade began with the Au...stralian bushfires still raging after the hottest and driest year on record, the world was soon (and still is) in the grip of the COVID-19 pandemic.
