Although it is intense in health care resources, by facilitating assessment and reconditioning, exvivo lung perfusion (EVLP) has the potential to expand the donor pool and improve lung transplant outcomes. However, inclusion criteria used in EVLP trials have not been validated.

This retrospective study from 2014 to 2018 reviewed our local state-based donation organization donor records as well as subsequent recipient outcomes to explore the relation between EVLP indications used in clinical trials and recipient outcomes. The primary outcome was primary graft dysfunction grade 3 at 24 hours, with 30-day mortality and posttransplant survival time as secondary outcomes, compared with univariate and multivariate analysis.

From 705 lung donor referrals, 304 lung transplantations were performed (use rate of 42%); 212 of recipients (70%) met at least 1 of the commonly cited EVLP initiation criteria. There was no significant difference in primary graft dysfunction grade 3 or 30-day mortality between recipients onsideration of EVLP inclusion criteria is required.We describe four cases of spinal cord ischemia resulting in paraplegia after peripheral venoarterial extracorporeal membrane oxygenation for cardiogenic shock. This is an uncommon, but possibly underreported, complication with significant irreversible long-term morbidity. While causes are likely multifactorial, it is possible that thrombosis may occur at the level of the mixing cloud due to turbulent flow. Additional studies will be needed to elucidate the true incidence of this complication and investigate whether flow dynamics may potentiate clot formation.

Venous-arterial extracorporeal membrane oxygenation (ECMO) is an established technique for intraoperative cardiopulmonary support in patients undergoing lung transplantation. Patients with pulmonary fibrosis have a higher risk to require it. The aim of this study was to identify risk factors for the need of intraoperative ECMO use.

Records of patients undergoing lung transplantation for pulmonary fibrosis at our institution between January 2010 and May 2018 were retrospectively reviewed. Univariate logistic regression analysis was used for statistical identification of risk factors.

There were 105 patients (34%) who required intraoperative ECMO support (ECMO+ group), and 203 (66%) did not (ECMO- group). Preoperative proof of pulmonary hypertension was identified as a risk factor for intraoperative ECMO support (odds ratio [OR], 3.8; 95% confidence interval [CI], 2.2-6.5; P < .01). Revealed mean pulmonary arterial pressure values exceeding 50 mm Hg and pulmonary vascular resistance values exceeding 9.tive course was more complicated in the ECMO+ group, long-term survival did not differ significantly.A fistula between a Zenker's diverticulum and the trachea has only been reported once in 1983. Here, we report a case of a fistula between a large Zenker's diverticulum and the trachea with complete occlusion of the esophagus. The fistula was repaired, performing an esophageal myotomy first, followed by proximal resection of the diverticulum, completion of the esophageal myotomy, transection of the fistula, and repair of the trachea. The surgical repair provided complete resolution of symptoms without complications.Three-dimensional (3D) in vitro models are excellent tools for studying complex biological systems because of their physiological similarity to in vivo studies, cost-effectiveness and decreased reliance on animals. The influence of tissue microenvironment on the cells, cell-cell interaction and the cell-matrix interactions can be elucidated in 3D models, which are difficult to mimic in 2D cultures. In order to develop a 3D model, the required cell types are derived from the tissues or stem cells. A 3D tissue/organ model typically includes all the relevant cell types and the microenvironment corresponding to that tissue/organ. For instance, a full corneal 3D model is expected to have epithelial, stromal, endothelial and nerve cells, along with the extracellular matrix and membrane components associated with the cells. Although it is challenging to develop a corneal 3D model, several attempts have been made and various technologies established which closely mimic the in vivo environment. In this review, three major technologies are highlighted organotypic cultures, organoids and 3D bioprinting. Also, several combinations of organotypic cultures, such as the epithelium and stroma or endothelium and neural cultures are discussed, along with the disease relevance and potential applications of these models. In the future, new biomaterials will likely promote better cell-cell and cell-matrix interactions in organotypic corneal cultures.The involvement of leukocytes in the pathophysiology of DR has mostly examined the role of monocytes and neutrophils with little emphasis on other immune cell types. In this study, we determined the systemic alterations in T cell subsets, myeloid cell types, NK cells, and NKT cells in the streptozotocin (STZ) mouse model of diabetic retinopathy (DR), and the role of NKT cells on retinal leukostasis and permeability changes. C57BL/6 J mice were made diabetic with 60 mg/kg dose of STZ given for 5-days. Flow cytometry assay measured the frequency of leukocyte subsets in the peripheral blood, spleen, and bone marrow of STZ- and vehicle-treated C57BL/6 J mice. Our results showed an increased proportion of memory CD8 T cells and interferon-gamma (IFN-γ) secreting CD8 T cells in the bone marrow of STZ-treated compared to control mice. HADA chemical clinical trial Subsequently, increased production of inflammatory monocytes in the bone marrow and an enhanced frequency of CD11b + cells in the diabetic retina were seen in STZ-treated compared to control mice. The diabetic mice also exhibited a decrease in total NKT and CD4+NKT cells. A monoclonal antibody-based approach depleted NKT cells from STZ-treated mice, followed by measurements of retinal vascular permeability and leukostasis. The depletion of NKT cells in STZ-treated mice resulted in a significant increase in vascular permeability in the retinal tissue. Together, our results strongly imply the involvement of NKT cells in regulating the pathophysiology of the diabetic retina.
