Allogeneic stem cell transplantation is associated with a high risk of treatment-related mortality mainly caused by infections and graft-versus-host disease (GVHD). GVHD is characterized by severe immune dysregulation and impaired regeneration of different tissues, i.e., epithelial barriers and the liver. The balance between pro- and anti-inflammatory cytokine influences the risk of GVHD. Interleukin-6 (IL-6) is a cytokine that previously has been associated with pro-inflammatory effects. However, more recent evidence from various autoimmune diseases (e...

BACKGROUND: Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Dressings are widely used to treat pressure ulcers and promote healing, and there are many options to choose from including alginate, hydrocolloid and protease-modulating dressings. Topical agents have also been used as alternatives to dressings in order to promote healing.A clear and current overview of all the evidence is required to facilitate decision-making regarding the use of dressings or topical agents for the treatment of pressure ulcers...

Plant grafting has been practiced widely in horticulture and proved as a useful tool in science. However, the mechanisms of graft healing or graft incompatibility remain poorly understood. In this study, Litchi chinensis cv. 'Jingganghongnuo' homograft ('J/J') and 'Jingganghongnuo'/'zhuangyuanhong' heterograft ('J/Z') as compatible and incompatible combination, respectively, was used to study transcriptional changes between incompatible and compatible graft during graft union formation. Anatomical observation indicated that three stages (2 h, 14 d and 21 d after grafting) were critical for graft union formation and selected for high-throughput sequencing...

OBJECTIVES: Haemodynamically stable patients admitted for coronary artery bypass grafting in acute myocardial infarction often undergo delayed surgery in order to avoid the risks of emergency surgery. However, initially stable patients undergoing delayed surgery may develop low cardiac output syndrome (LCOS) during the waiting period, which might be a major drawback of this strategy. We aim to define risk factors and clinical consequences of LCOS during the waiting period. METHODS: A total of 530 consecutive patients with acute myocardial infarction (33% non-ST-segment elevation myocardial infarction and 67% ST-segment-elevation myocardial infarction) underwent isolated coronary artery bypass grafting between 2008 and 2013...

REVIEW
Ali S Omrani, Reem S Almaghrabi
Patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are at increased risk of invasive fungal infections, especially during the early neutropenic phase and severe graft-versus-host disease. Mold-active prophylaxis should be limited to the highest risk groups. Empiric antifungal therapy for HSCT with persistent febrile neutropenia is associated with unacceptable response rates, unnecessary antifungal therapy, increased risk of toxicity, and inflated costs. Empiric therapy should not be a substitute for detailed work up to identify the cause of fever in such patients...

INTRODUCTION: Transplant surgeons conventionally select against livers displaying high degrees (>30%) of macrosteatosis (MaS), out of concern for primary non-function or severe graft dysfunction. As such, there is relatively limited experience with such livers, and the natural history remains incompletely characterized. We present our experience of transplanted livers with high degrees of MaS and microsteatosis (MiS), with a focus on the histopathologic and clinical outcomes. METHODS: 29 cases were identified with liver biopsies available from both the donor and the corresponding liver transplant recipient...

Allogeneic haematopoietic stem cell transplantation (HSCT) from an human leukocyte antigen (HLA)-identical donor can be curative for eligible patients with non-malignant and malignant haematological disorders. HSCT from alternative donor sources, such as HLA-mismatched haploidentical donors, is increasingly considered as a viable therapeutic option for patients lacking HLA-matched donors. Initial attempts at haploidentical HSCT were associated with vigorous bidirectional alloreactivity, leading to unacceptably high rates of graft rejection and graft-versus-host disease (GVHD)...

Measurement of exhaled carbon monoxide (eCO) might help in the selection of lung grafts during ex vivo lung perfusion since its endogenous production is increased under ischemia reperfusion. The objective of this study was to measure eCO variations depending on the extent of lung ischemia reperfusion injuries. Using a porcine model and a laser spectrometer instrument, eCO was measured during ex vivo lung perfusion. eCO was compared after 30 min (D0) or 24 h (D1) of cold ischemia. The ability of eCO to distinguish lungs deemed suitable for transplantation was evaluated...

Kidney transplantation is recognised as the gold standard treatment of end-stage renal disease in most children, with excellent graft survival rates. When graft failure occurs, renal transplant recipients (RTRs) have the option of removal of the transplant (graft nephrectomy [GN]), or leaving the failed transplant in situ. The aims of this review are to discuss the indications for GN, surgical techniques, outcomes after GN (including risks of allosensitisation and the impact on subsequent transplants), and the possible role of routine GN in the asymptomatic RTR with a failed renal allograft...

Correction manoeuvres are as important as the other issues such as hardware selection, graft options, fusion and osteotomy techniques in the surgical treatment of spinal deformities.The property of materials demonstrating both viscous and elastic characteristics when undergoing deformation is called visco-elasticity. Purely elastic materials change in shape with a stress, and go back to their initial form when the stress is removed. However, visco-elastic materials, like the spine, may protect their new formation unless a back stress is applied...

A fluorescent "turn-on" sensor for fast measuring aliphatic biogenic amines (BAs) was developed based on fluorescent carboxylated polyfluorene (PFTBTCOOH)/ chitosan-graft-oleic acid (CS-graft-OA) micelles. In this system, biobased CS-graft-OA micelles prepared by graft modification of chitosan with oleic acid serve as the vector of hydrophobic fluorescent probe. Bright "turn-on" fluorescence was achieved by the intermolecular fluorescence resonance energy transfer (FRET) of the encapsulated PFTBTCOOH driven by the formation of electrostatic complex with aliphatic BAs, which facilitate a visual identification...

The process of ageing has an impact on the entire human body including the organ systems. In transplantation, professionals are daily faced with risk assessment of suitable donor offers , whether to accept a liver graft for a specific recipient. In this context, livers from elderly donors are more frequently accepted for transplantation, to increase the donor pool and compensate the high waiting list mortality. In the current practice it is not unusual to accept 60-year old donor livers for transplantation, as the donor demographics have significantly changed over the years...
