When Nichelle Obar learned she was pregnant with her second child last year, she never expected that her pregnancy, or her baby, would make history. But when the 40-year-old food-and-beverage coordinator from Hawaii and her fiancé Christopher Constantino went to their 18-week ultrasound, they learned something was wrong. The heart was larger than it should have been, and there was evidence that fluid was starting to build up around the organ as well. Both were signs that the fetus was working extra hard to pump blood to its fast-growing body and that its heart was starting to fail. Obar’s doctor knew what coul...

Pulmonary compromise has been shown to significantly contribute to non-relapse mortality after hematopoietic stem cell transplantation (or HSCT).1-4 The etiology of these pulmonary complications includes intrapulmonary causes of fibrosis and toxicities from treatment regimens or infections (restrictive lung disease), graft-versus-host disease or bronchiolitis obliterans syndrome (obstructive lung disease), and vascular abnormalities (e.g. pulmonary hypertension), as well as extrapulmonary causes such as weakness or sclerodermatous GVHD.

Authors: Yi T, Li X, Wang E, Zhang Y, Fu Y, Li J, Jiang T Abstract BACKGROUND Acute graft-versus-host disease (aGVHD) limits the wider application of hematopoietic stem cell transplantation (HSCT). We explored the relationship between the Nrf2-ARE signaling pathway and aGVHD and identified effective and efficient therapeutic targets for the prevention and management of aGVHD following HSCT. MATERIAL AND METHODS C57BL/6 and BALB/c mice were used to establish the aGVHD model. The bone marrow and spleen mononuclear cells were separated from the donor mice and injected into the caudal vein of recipient mice that had un...

Conclusion: MSCs-HO-1 have an enhanced ability to improve LPS-induced inflammatory and oxidative damage in PVECs, and the mechanism may be partially associated with the enhanced paracrine function of the stem cells. These data encourage further testing of the beneficial effects of MSCs-HO-1 in ALI animal models.Cell Physiol Biochem 2018;49:101 –122

Transplantation-associated thrombotic microangiopathy (TA-TMA) is a complication of hematopoietic stem cell Transplant (HSCT) characterized by microangiopathic hemolytic anemia, thrombocytopenia, and microvascular thrombosis, which can lead to severe end-organ injury. The reported incidence of TA-TMA ranges from 12 – 39%1–3 and mortality can be as high as 90% in severe or untreated cases.3–5 The pathogenesis of TA-TMA is not entirely understood, but is thought to be multifactorial, leading to microvascular endothelial cell injury and formation of microthrombi predominantly in the kidneys, lungs, gastroin ...

Authors: Rosso L, Zanella A, Righi I, Barilani M, Lazzari L, Scotti E, Gori F, Mendogni P Abstract Lung transplantation is the only therapeutic option for end-stage pulmonary failure. Nevertheless, the shortage of donor pool available for transplantation does not allow to satisfy the requests, thus the mortality on the waiting list remains high. One of the tools to overcome the donor pool shortage is the use of ex-vivo lung perfusion (EVLP) to preserve, evaluate and recondition selected lung grafts not otherwise suitable for transplantation. EVLP is nowadays a clinical reality and have several destinations of use. ...

Authors: Petrella F, Spaggiari L Abstract Lung transplantation remains the definitive curative treatment for end-stage lung disease. However, future applications of tissue bioengineering could overcome the donor organ shortage and the need for immunosuppression. The final goal of lung tissue engineering is to recreate the whole spectrum of specialized lung tissues and thereby provide physiologic functions through bioengineered conducting airways, vasculature and gas exchange tissue. This review focuses on ongoing research in artificial lung development, open questions, achievements to date and how tissue engineeri...
