'Lab-grown' rat kidney successfully transplanted

Conclusion This early stage research has developed a new way of growing a bioengineered rat kidney in the laboratory that can produce urine when implanted into a living rat. The researchers have also shown that at least the first stage of this process (removing the cells from a donor kidney) can be achieved with a human kidney. Due to limited availability of donor kidneys for people with kidney disease, researchers and doctors would like to be able to grow human kidneys in the laboratory. This research could be an early step towards developing a potential method for ‘growing’ kidneys in the laboratory that could be used in humans. However, as the authors themselves acknowledge, many hurdles remain. For example, although the bioengineered rat kidneys did filter blood and produce urine, there were signs that these new kidneys were not functioning exactly as a normal adult rat kidney would. This suggested that the kidneys might need longer to mature in the laboratory before transplant, or to be grown in different conditions. If this research is to be extended to humans, the researchers will need to determine an appropriate source of the right kind of human cells and kidney scaffolds for developing human bioengineered kidneys. The current study successfully produced human and pig kidney scaffolds, however, as with transplantable functioning donor kidneys, human kidneys suitable for use as scaffolds may not be easy to obtain. One of the researchers has been reporte...

AbstractThe overall aim of this scoping review of the literature is twofold: (1) to provide an overview of all instruments that have been used to assess health-related quality of life (HRQoL) after solid organ transplantation and (2) to provide a list of health items they include to support future studies on the development of a new-generation HRQoL instrument. All studies that administered any form of HRQoL instrument to post-transplant solid organ recipients were identified in a comprehensive search of PubMed (MEDLINE), Embase, and Web of Science, with a cut-off date of May 2018. The search used various combinations of t...

Authors: Naranjo M, Lo KB, Mezue K, Rangaswami J Abstract Pulmonary hypertension is not uncommon in patients with renal disease and vice versa; therefore, influences treatments and outcomes. There is a large body of literature on pulmonary hypertension in patients with kidney disease, its prognostic implications, economic burden, and management strategies. However, the converse, namely the hemodynamic effects of pulmonary hypertension on kidney function (acute and chronic kidney injury) is less studied and described. There is also increasing interest in the effects of pulmonary hypertension on kidney transplant out...

Authors: Salehi S, Tran K, Grayson WL Abstract In the past, a diagnosis of organ failure would essentially be a death sentence for patients. With improved techniques for organ procurement and surgical procedures, transplantations to treat organ failure have become standard medical practice. However, while the demand for organs has skyrocketed, the donor pool has not kept pace leading to long recipient waiting lists. Organ preservation provides a means to increase the number of available transplantable organs. However, there are significant drawbacks associated with cold storage, the current gold standard. To addres...

A history of melanoma within the preceding 5 years is commonly considered a contraindication to solid organ transplantation. We investigated how a pretransplant history of melanoma impacts patient survival and melanoma recurrence. Institutional Review Board approval was obtained, and Duke’s retrospective database was used to identify 4552 patients who underwent a solid organ transplant at Duke University from 1 January 2001 to 31 December 2016. Data with regard to the transplant, melanoma characteristics, rejection episodes, and survival were recorded. Of 4552 patients who underwent a solid organ transplant, 12 (0.3%...

Conclusion Employment status pre-transplant being highly associated with employment status post-transplant, the process promoting return to work should be started well before surgery. Biomedical, psychological and social factors must be taken into account to promote return to work in transplanted patients.

However, due to the mismatch in demand and supply of the organ donors and recipients, organ donation after circulatory death has increased recently all over the world. Kidneys, liver and lungs are being used for transplantation from Donors after circulatory death (DCDDs). Recently, he...

Abstract Despite decades of formidable exploration, multi-organ ischemia-reperfusion injury (IRI) encountered, particularly amongst elderly patients with clinical scenarios, such as age-related arteriosclerotic vascular disease, heart surgery and organ transplantation, is still an unsettled conundrum that besets clinicians. Remote ischemic conditioning (RIC), delivered via transient, repetitive noninvasive IR interventions to distant organs or tissues, is regarded as an innovative approach against IRI. Based on the available evidence, RIC holds the potential of affording protection to multiple organs or tissues, w...

We report that the disruption of excitation-contraction coupling contributes to impaired force generation in the mouse model of Sod1 deficiency. Briefly, we found a significant reduction in sarcoplasmic reticulum Ca2+ ATPase (SERCA) activity as well as reduced expression of proteins involved in calcium release and force generation. Another potential factor involved in EC uncoupling in Sod1-/- mice is oxidative damage to proteins involved in the contractile response. In summary, this study provides strong support for the coupling between increased oxidative stress and disruption of cellular excitation contraction mac...

Abstract BACKGROUND Donor hypernatremia has been associated with reduced graft and recipient survival after heart, liver, kidney, and pancreas transplantation. However, it is unknown what effect donor hypernatremia has on graft and recipient outcomes after lung transplantation. The aim of this study was to investigate the relation of donor hypernatremia with the duration of postoperative mechanical ventilation, the incidence of severe primary graft dysfunction, and survival following lung transplantation. MATERIAL AND METHODS We analyzed all consecutive lung transplantations performed in adult patients at our cent...
