Outcome of transplanted donor corneas with more than 6 h of death-to-preservation time [PDF]

Indian Journal of Ophthalmology, 2016
Purpose: In tropical countries, physicians are skeptic in using corneas with death-to-preservation time (DTPT) >6 h, concerns being endothelial cell viability and microbial contamination on prolonged DTPT.

Primary Graft Failure, Infection, and Endothelial Cell Density in Corneal Transplants With Increased Death-to-Preservation Time. [PDF]

Cornea, 2021
Purpose: To ascertain whether death-to-preservation time (DPT) is associated with donor endothelial cell density (ECD), primary graft failure (PGF), and infection. Methods: Donor corneas aged older than 10 years with ECD 2000 to 4500 cells/mm2 were procured between 2011 and 2018 by ...

Negative impact of prolonged cold storage time before machine perfusion preservation in donation after circulatory death kidney transplantation.

Transplant International, 2016
Kidney grafts are often preserved initially in static cold storage (CS) and subsequently on hypothermic machine perfusion (MP). However, the impact of CS/MP time on transplant outcome remains unclear. We evaluated the effect of prolonged CS/MP time in a single-center retrospective cohort of 59 donation after circulatory death (DCD) and 177 matched ...

Effects of ex vivo machine perfusion on preservation time and donor age in donation after brain death heart transplantation

Journal of Heart and Lung Transplantation
With encouraging early experience, ex vivo machine perfusion (MP) systems are increasingly employed in heart transplantation. In this study, utilizing a national registry database, 2 separate analyses were performed to evaluate the effects of MP on graft preservation time (total n = 22,794; n = 308 with MP) and donor age (total n = 22,581; n = 95 with ...

10 °C Storage for the Preservation of Pig Kidney Grafts: A Porcine Autotransplant Model [PDF]

Transplantation Direct
Background. Optimization of organ storage is essential to improve outcomes in kidney transplantation. Recent studies in lung transplantation highlight the impact of temperature on organ preservation, leading to a shift from traditional 4 °C “on-ice ...

Alternative Preservation Strategies of Donation After Circulatory Death Hearts: Effect of Cold Ischemia Time Before Normothermic Machine Perfusion. [PDF]

J Am Heart Assoc
Background Donation after circulatory death (DCD) offers a promising strategy to expand the donor pool by 20% to 30%. However, DCD heart grafts experience warm ischemia injury, making effective graft viability assessment before transplantation prudent.

Viscoelastic properties of cat tendon: Effects of time after death and preservation by freezing [PDF]

Journal of Biomechanics, 1968
Abstract In this study postmortem changes in the character of the stress-strain limit cycle were analyzed for cat extensor communis and extensor lateralis tendons maintained in a stream of Ringer's solution and loaded with a short series of symmetrical triangular-wave stress cycles.

Appropriate timing for hypothermic machine perfusion to preserve livers donated after circulatory death

Molecular Medicine Reports, 2020
Hypothermic machine perfusion (HMP) is a method that can be more effective in preserving donor organs compared with cold storage (CS). However, the optimal duration and the exact mechanisms of the protevtive effects of HMP remain unknow. The present study aimed to investigate the adequate perfusion time and mechanisms underlying HMP to protect livers ...

Impact of time interval between donor brain death and cold preservation on long-term outcome in lung transplantation [PDF]

European Journal of Cardio-Thoracic Surgery, 2016
Brain death (BD) is associated with various systemic responses and a cascade of inflammatory reactions. It is still unknown how the time interval from BD to cold preservation (CP) affects outcome after lung transplantation (LTx). This report investigates the impact of the time interval from BD to CP on long-term outcome in LTx.We reviewed 250 ...
