Health care contributes to the climate change burden, and measures should be taken to mitigate these effects. This Perspective discusses the carbon footprint of surgery in gastroenterology and hepatology and offers an overview of sustainable strategies.
Intestinal gluconeogenesis (IGN) is a conserved mechanism documented in all vertebrates and it has a crucial role in energy homeostasis and metabolic processes. This Perspective provides an overview of IGN and discusses its importance in natural selection.
Advances in artificial intelligence (AI) are changing endoscopy and gastrointestinal surgery, including computer-assisted detection and diagnosis, computer-aided navigation, robot-assisted intervention and automated reporting. This Perspective introduces the role of AI in computer-assisted interventions in gastroenterology with insights on regulatory aspects and the challenges ahead.
The gastrointestinal tract is involved in COVID-19, gastrointestinal symptoms can occur and marked changes in the gut microbiota have been observed. This Perspective highlights interactions between the gut microbiota and SARS-CoV-2 infection and increasing interest in the gut–lung axis.
Secretory antibodies regulate intestinal bacteria, but their specificity and dependence on T cells have been matters of debate. This Perspective argues that bacteria-reactive antibodies are highly specific and that their production is under the control of T cells.
Archaea are an overlooked member of the human gut microbiota. This Perspective discusses key characteristics of archaea, their role in human health and physiology, and the clinical relevance of methanogenic archaea in the human gastrointestinal tract.
The history of hepatitis C virus (HCV) is a role model for successful basic, translational and clinical research. In this Perspective, the authors chart a timeline of breakthroughs in hepatitis C research, from discovery to cure.
Multiomics advance our understanding of disease progression and can facilitate drug discovery. In this Perspective, current knowledge and applications of omics platforms in inflammatory bowel disease diagnosis and in identifying risk factors are discussed.
Ceresa et al. discuss machine perfusion technologies for liver preservation and transplantation, including the potential of hypothermic and normothermic machine perfusion to improve preservation time and organ quality, as well as the future applications of perfusion technologies.
