The gut microbiota plays a fundamental role in Hepatitis C Virus (HCV)-related liver disease. Indeed, HCV infection alters the gut microbiota, whereas intestinal dysbiosis induces an underlying inflammatory state. This status may lead to liver disease progression. The advent of direct acting antivirals (DAAs) was a turning point in the history of HCV infection, which enhances the chances of recovery. Beyond the elimination of the virus, DAA therapy can affect the gut microbiota of the HCV patient. The study of the gut microbiota in the patient with HCV-related liver disease could be the first step in understanding the etiopathogenesis of hepatopathy thereby opening the way to new therapeutic opportunities. Herein we evaluate current knowledge regarding the gut microbiota in patients with HCV infection and the impact of DAA therapy.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Background: Dietary fiber supports metabolic health via microbial fermentation, producing short-chain fatty acids (SCFAs). However, metabolic responses to fiber vary between individuals, potentially due to differences in gut microbiota composition. The Prevotella-to-Bacteroides (P/B) ratio has emerged as a potential biomarker for fiber responsiveness.

Metaflammation, a chronic immune response triggered by metabolic dysregulation, poses significant threats to gut-liver homeostasis in aquaculture species. To understand the progression of metaflammation, it is crucial to examine the role of SOCS8 deficiency in socs8 zebrafish, as this species may serve as a disease model for metabolic disorders due to the gradual dysregulation of immunity, metabolism, and the gut microbiota observed in them. This study examines the immune-metabolic crosstalk in grass carp, subjected to soybean meal-induced enteritis, and in socs8 zebrafish under genetic and dietary stress.

Perioperative neurocognitive disorders (PNDs) are common complications following surgery, especially in elderly patients, and are characterized by memory loss, attention deficits, and impaired executive function. The pathogenesis of PNDs involves a complex interplay of neuroinflammation, neurotransmitter imbalance, epigenetic modifications, and gut-brain axis disruption. This review summarizes the latest findings on the mechanisms underlying PNDs, with a focus on microglial activation, interleukin imbalance, and NLRP3 inflammasome-mediated pyroptosis.
