Brazil, like most countries in the world, experiences the expansion of extended criteria donors, mainly due to the aging of the population and the obesity epidemic. Concerns regarding the quality of these organs along with the vast territorial areas of the country compromise the utilization rate of livers from donors and aggravate the discrepancy between the number of liver transplants performed and the needed. Ex situ liver machine perfusion offers superior preservation for livers from extended criteria donors, limiting cold ischaemia time and offering the possibility of evaluation of their function before transplantation as well as the reconditioning of marginal organs. Objections such as the financial cost, difficulty in transporting the device between hospitals, and demand of trained professionals in the handling of the device must be pondered with the possibility of increasing the number of transplants and the utilisation rate of donor organs. The optimal use of this resource, through the careful selection of donors and the appropriate technical and scientific knowledge, can ensure an effective and successful implementation of this technology.

Uncontrollable haemorrhage and associated microbial contamination in the battlefield and civilian injuries pose a tremendous threat to healthcare professionals. Such traumatic wounds often necessitate an effective point-of-care solution to prevent the consequent morbidity owing to blood loss or haemorrhage. However, developing superior hemostatic materials with anti-infective properties remains a challenge.

Human liver organoids (HLOs) derived from pluripotent stem cells hold potential for disease modeling and high-throughput compound screening due to their architectural and functional resemblance to human liver tissues. However, reproducible, scale-up production of HLOs for high-throughput screening (HTS) presents challenges. These include the high costs of additives and growth factors required for cell differentiation, variability in organoid size and function from batch to batch, suboptimal maturity of HLOs compared to primary hepatocytes, and low assay throughput due to excessive manual processes and the absence of assay-ready plates with HLOs.

Circulating histones have been identified as essential mediators that lead to hyperinflammation, platelet aggregation, coagulation cascade activation, endothelial cell injury, multiple organ dysfunction, and death in severe patients with sepsis, multiple trauma, COVID-19, acute liver failure, and pancreatitis. Clinical evidence suggests that plasma levels of circulating histones are positively associated with disease severity and survival in patients with such critical diseases. However, safe and efficient therapeutic strategies targeting circulating histones are lacking in current clinical practice.

Liver resection represents a main curative treatment for patients with early-stage hepatocellular carcinoma (HCC), but there is a rather high incidence of postoperative HCC relapse, which severely shortens long-term survival time. Currently, no standard adjuvant strategies are available for preventing HCC relapse in clinical practice. Impaired natural killer (NK) cell anti-tumor immunity has been disclosed as a crucial root of HCC relapse, indicating that reinstating NK cell anti-tumor immunity may show promise to curb HCC relapse.

Marginal liver grafts, such as those from cardiac death donors and donors with steatotic organs, are highly vulnerable to ischemia-reperfusion injury. In addition, ex situ graft alteration, either by reduction or splitting, will prolong the static cold storage time and amplify the ischemia-reperfusion injury. Hypothermic oxygenated machine perfusion has the potential to end the oxygen deprivation during preservation and accordingly improve outcomes in some marginal grafts that have been traditionally discarded.
