Summary: This article introduces a technique for thermoregulation of cardiac preservation solution using the SherpaPak device prior to heart transplantation. To ensure optimal organ function, the cardiac preservation solution needs to be cooled to the ideal temperature range, and if the temperature exceeds this range, it should be placed in ice water. However, the SherpaPak device has limitations in immediately correcting initial temperatures outside of the normal range, and therefore, it is recommended to include this simple step in the standard procedure to ensure effectiveness.

Summary: The study demonstrated that HPG-based preservation solution was more effective than UWS in initial blood washout during kidney perfusion and in preventing cold ischemia injury; after autotransplantation, kidneys preserved with HPG showed better functional recovery and less tissue damage compared to those preserved with UWS.

Summary: This study evaluated the clinical benefits of the Paragonix SherpaPak Cardiac Transport System (SCTS) compared to traditional ice cold storage (ICS) in heart transplantation. The results showed that the use of SCTS can reduce the rate of severe primary graft dysfunction (PGD) and decrease the utilization of mechanical circulatory support (MCS) in patients with prolonged ischemic time.

Summary: Kidney transplantation is the preferred treatment for end-stage kidney disease, and optimizing organ condition is crucial due to the shortage of transplantable organs. This study demonstrated that supplementing the preservation solution with the S1R agonist fluvoxamine reduced cold and warm ischemic injury, improved kidney function, mitigated histological injury, and reduced inflammation. The results suggest that S1R agonists have great potential in improving organ preservation and alleviating the problem of organ shortages.

Summary: This study compared the preservative capacity of gluconate-lactobionate-dextran (Unisol) solutions and histidine-tryptophan-ketoglutarate (HTK) solution. The results showed that Unisol-based solutions demonstrated faster rebeating time and better contractility after cardiac transplantation compared to HTK. The expression of proinflammatory markers was also reduced in Unisol-treated animals.

Summary: Organ transplantation is the last resort for treating organ failure, but the shortage of organs remains a challenge. To address this issue, there is a need to expand the donor pool and optimize preservation conditions to improve the quality of transplanted organs.

Summary: Heart transplantation is the best surgical treatment for end-stage heart failure patients, but the increasing age and high-risk factors of HTx candidates pose challenges. Donor organ preservation techniques, such as controlled hypothermia and machine perfusion, have shown potential in improving outcomes. However, the superiority of these techniques over traditional static cold storage is still debatable. This review aims to critically assess the available clinical data on donor heart preservation strategies for HTx.

Summary: Prolonged cooling of cells can result in cell death, with both apoptosis and ferroptosis playing a role. Preservation solutions like the University of Wisconsin Cold Storage Solution (UW) have been shown to improve survival and extend preservation limits. However, the exact mechanisms of how these solutions exert their cold protection are still unclear. This study explored the effects of cooling on lipid peroxidation and ATP levels, as well as the actions of apoptosis and ferroptosis blockers. The results suggest that cooling-induced cell death is mainly caused by ferroptosis, and treatment with Ferrostatin-1 or SUL150 can effectively prevent ferroptosis and preserve ATP.

Summary: This study investigates the current trends and obstacles to the implementation of dynamic perfusion concepts in liver transplantation on an international scale. A web-based survey was conducted among experts from 70 centers in 34 countries. The results show that while dynamic preservation techniques are increasingly used in clinical practice, financial, knowledge, and personnel challenges remain.

Summary: The study found that ADD10, a novel clinical grade antioxidant, can significantly reduce tissue damage and cell death during static cold storage (SCS), as well as decrease reactive oxygen species (ROS) levels and improve cellular bioenergetics. Preliminary in vivo studies also suggested a beneficial effect of ADD10 on renal function. Therefore, the addition of ADD10 to preservation solutions could effectively protect organs and enhance their functionality during transplantation.

Summary: This study evaluated the natural course of tricuspid regurgitation (TR) among patients who did not undergo tricuspid valve repair (TVR) at the time of lung transplant. The results showed that the severity of TR improved or remained unchanged in most patients after transplant, indicating that TVR may not be necessary for most lung transplant recipients.

Summary: Patients undergoing lung transplantation for pulmonary venous-occlusive disease (PVOD) had better initial survival compared to those with primary pulmonary hypertension (PPHTN), but this advantage disappeared after 1 year. The use of donation after circulatory death donors was associated with lower short-term survival rates.
