2023 was the most memorable year on record for obesity. The American Academy of Pediatrics recognized the complex, multifactorial nature of obesity and the broad range of treatments necessary to care for pediatric patients. The first-ever triple agonist and high-potency oral GLP1 agonist was introduced with unprecedented results.
In 2023, there were significant advancements in trials of interventions to reduce mortality and morbidity from alcohol-related liver disease, spanning the entire spectrum of disease: primary prevention to reduce overall alcohol-related harm, secondary prevention to attenuate fibrosis progression and tertiary prevention using antibiotics for severe alcohol-associated hepatitis.
Metastatic colorectal cancer is a heterogeneous disease associated with poor patient outcomes. Although the past decade has seen few first-line treatment advances, key studies published in 2023 established new options for late-line therapy of the disease with and without oncogenic drivers, thus expanding the continuum of care in metastatic colorectal cancer.
Important studies published in 2023 outlined new agents and strategies for the management of inflammatory bowel disease. Therapeutic ambitions for the management of inflammatory bowel disease were raised by the success of combinations of biologic agents in ulcerative colitis and early surgical resection in Crohn’s disease.
New light is being shed on the interactions between the gut microbiome, cancer cell signalling and the host immune response. With this knowledge, microbiota-based approaches for improving cancer prevention, prognostication and therapy have started to materialize and will contribute to reducing the global cancer burden.
In 2023, we witnessed advances in allocation policies and marginal donors, including living donors. Key improvements included the uncapped Model for End-stage Liver Disease 3.0 score, unveiled machine perfusion trials to standard deceased donors and lessons from the aborted living donor liver transplantations.
Enteric nervous system function is essential for survival. Studies published in 2023 have provided important novel insights into the mechanisms that regulate its development and maintenance, and demonstrate how it can be restored when these mechanisms fail.
Key studies published in 2022 highlight the emergence of several novel drugs for inflammatory bowel disease. Head-to-head trials and network meta-analyses have also been conducted to identify the sequencing of these treatments, but we still have a long way to go to achieve personalized medicine.
The gut microbiome field is shifting from association to modulation. Microbiota-based treatments come in many shapes and sizes, ranging from dietary intervention to live bacterial products. Recent methodological advances are instrumental to developing innovative new treatment strategies in microbiome-linked pathologies.
