Health systems'resilience during the COVID-19 pandemic: A South African polio surveillance case study.

Background: More needs to be known on how the South African health system contained the coronavirus disease 2019 (COVID-19) pandemic and maintained the core business of health service delivery. We describe the practices that have shown to affect the health systems' resilience in ensuring maintenance of polio surveillance and immunization systems in South Africa (SA) during the COVID-19 pandemic.

Methodology: This is a descriptive, reflective desk review study using the South African polio surveillance systems and immunization coverage as a case study.

Development of a bespoke finite element wear algorithm to investigate the effect of femoral centre of rotation on the wear evolution in total knee replacements.

Total Knee Replacements (TKRs) are a commonly used treatment to help patients suffering from severely damaged knee joints, which is normally brought on by osteoarthritis. The aim of the surgery is to reduce pain and regain function of the joint, however, some of these implants fail prematurely with implant wear being one of the main factors of failure. Computational analysis is an efficient tool that can provide an in-depth insight on the evolution of wear, before utilising experimental techniques which are time-consuming and costly.

Barriers to accessing appendectomy in the public sector health system in the Western Cape Province, South Africa.

Background: Appendectomy is the surgical treatment for acute appendicitis and barriers to timely care can lead to morbidity and mortality. In South Africa, patients experience delays during the stages of seeking, reaching, and receiving care. This study explored the perceptions and experiences of barriers to accessing appendectomy among patients, caregivers, and surgeons employed at selected public hospitals in the Western Cape, South Africa.

Wastewater Surveillance for Poliovirus in Selected Jurisdictions, United States, 2022-2023.

Wastewater testing can inform public health action as a component of polio outbreak response. During 2022-2023, a total of 7 US jurisdictions (5 states and 2 cities) participated in prospective or retrospective testing of wastewater for poliovirus after a paralytic polio case was identified in New York state. Two distinct vaccine-derived poliovirus type 2 viruses were detected in wastewater from New York state and New York City during 2022, representing 2 separate importation events.

Planetary health learning objectives: foundational knowledge for global health education in an era of climate change.

Planetary health is an emerging field that emphasises that humans depend on a healthy Earth for survival and, conversely, that the sustainability of Earth systems is dependent on human behaviours. In response to member demands for resources to support teaching and learning related to planetary health, the Consortium of Universities for Global Health (CUGH) convened a working group to develop a set of planetary health learning objectives (PHLOs) that would complement the existing ten CUGH global health learning objectives. The eight PHLOs feature Earth system changes, planetary boundaries, and climate change science; ecological systems and One Health; human health outcomes; risk assessment, vulnerability, and resilience; policy, governance, and laws (including the UN Framework Convention on Climate Change and the Paris Agreement); roles and responsibilities of governments, businesses, civil society organisations, other institutions, communities, and individuals for mitigation, adaptation, conservation, restoration, and sustainability; environmental ethics, human rights, and climate justice; and environmental literacy and communication.
