Australian Journal of Primary Health: Impacts of long COVID on disability, function and quality of life for adults living in Australia
ABSTRACT Background To describe the impact of long COVID on disability, function and quality of life among adults living in Australia. Method People aged >18 years with a history of COVID-19 infection confirmed by polymerase chain reaction or rapid antigen test were eligible for this cross-sectional survey. The World Health Organization Disability Assessment Schedule 2.0 measured disability and function, and the 36-Item Short Form Health Survey assessed quality of life. Results Participants (n = 121) r...

iScience: SARS-CoV-2 infection drives local inflammation of the intestinal epithelium in immunocompromised patients with cancer
Cancer patients undergoing transplantation-based treatments can develop graft-versus-host disease (GVHD), an inflammatory condition that increases mortality risk. In this study, we analyzed three cancer patients with severe inflammatory disorders following SARS-CoV-2 infection using high-resolution microscopy and spatial transcriptomics on pre- and post-infection GI biopsies. We found that up to 49 days after infection, the duodenal epithelium retained COVID viral elements, showed increased expression of vir...

Brain Structure and Function: Metabolic brain changes in post-acute COVID-19: systematic review and meta-analysis of [18F]-FDG-PET findings
ABSTRACT Individuals with long COVID exhibit neurological and psychiatric symptoms that often persist well beyond the initial SARS-CoV-2 infection. Studies using [18F]-FDG positron emission tomography (FDG-PET) have revealed diverse abnormalities in brain glucose metabolism during the post-acute phase of COVID-19. We conducted a systematic review and meta-analysis to assess the spatial distribution and heterogeneity of brain metabolic changes in patients in the post-acute phase of COVID-19 relative to contr...

The Lancet: The Lancet Countdown on health and plastics
Plastics are a grave, growing, and under-recognised danger to human and planetary health. Plastics cause disease and death from infancy to old age and are responsible for health-related economic losses exceeding US$1·5 trillion annually. These impacts fall disproportionately upon low-income and at-risk populations. The principal driver of this crisis is accelerating growth in plastic production—from 2 megatonnes (Mt) in 1950, to 475 Mt in 2022 that is projected to be 1200 Mt by 2060. Plastic pollution has al...

Nature: Respiratory viral infections awaken metastatic breast cancer cells in lungs
ABSTRACT Breast cancer is the second most common cancer globally, with most deaths caused by metastatic disease, often following long periods of clinical dormancy1. Understanding the mechanisms that disrupt the quiescence of dormant disseminated cancer cells (DCCs) is crucial for addressing metastatic progression. Infections caused by respiratory viruses such as influenza and SARS-CoV-2 trigger both local and systemic inflammation. Here we demonstrate, in mice, that influenza and SARS-CoV-2 infections lead ...
