Modeling aortorenal perfusion in suprarenal coarctation repair

Suprarenal abdominal aortic coarctation (SAAC) is a congenital midaortic syndrome that develops owing to a developmental anomaly in the fusion of the embryonic dorsal aortae. This condition is associated with severe hypertension, which is usually the indication for intervention. Open surgery is the primary treatment and it typically involves thoracoaortic bypass (TAB), and less commonly patch aortoplasty (PA). Bypass to the visceral vessels has also been performed in conjunction with TAB or PA. The majority undergoing intervention for SAAC are children and adolescents; therefore, the benefits of surgical intervention must be weighed against the risks of surgery on the developing aorta.

This report is the first instance in which a patient with severe PAH, survived a successful atrial septal defect (ASD) repair and bilateral lung transplantation during puerperium. Patient concerns: A 42-year-old pregnant woman with congenital heart disease (CHD) and severe PAH was admitted to our hospital for the management of pregnancy and delivery. The patient was diagnosed with severe PAH in 2013, and no significant improvements or deteriorations were found until this pregnancy-related hospital admission. Diagnosis: The patient was diagnosed with CHD and severe PAH in 2013 with color Doppler echocardiography, righ...

Abstract OBJECTIVES: With a focus on renal function, the goal of this multicentre study was to assess peri-operative complications and late mortality of open surgical repair (OSR) of juxtarenal abdominal aortic aneurysms (JRAAA). METHODS: From February 2005 to December 2015, 315 consecutive patients undergoing elective OSR of a JRAAA in five French academic centres were evaluated retrospectively. The definition of JRAAA was an aortic aneurysm extending up to but not involving the renal arteries, i.e., a short neck

In this study, analysis of antioxidant defense was performed on the blood samples from 184 "aged" individuals aged 65-90+ years, and compared to the blood samples of 37 individuals just about at the beginning of aging, aged 55-59 years. Statistically significant decreases of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were observed in elderly people in comparison with the control group. Moreover, an inverse correlation between the activities of SOD-1, CAT, and GSH-Px and the age of the examined persons was found. No age-related changes in glutathione reductas...

​BY JENNIFER TUONG; IVAN KHARCHENKO; JEAN LUC AGARD; &AHMED RAZIUDDIN, MDA 65-year-old man who had HIV well-controlled with highly active antiretroviral therapy, hypertension, sciatica, and restless leg syndrome presented to the emergency department with left leg pain. He also had had chemotherapy and radiation for anal cancer. The patient said the pain had started 45 minutes earlier when he was sitting on the toilet.He described the pain as sore in quality and 10/10 on the pain scale. He reported that it had started in his lower back and radiated to his left leg. He said he had had no trauma or weakness to the regio...

Conclusion Massive SI and immune cell paralysis associated with ACLF represent the extreme severity of CAID in response to an infectious or sterile challenge. The severe immune disturbance plays a pivotal role in the pathogenesis of the distinctive features of ACLF: organ failure and bacterial infection susceptibility. Excessive SI in ACLF results from the massive activation and dysfunction of an innate immune system challenged by increased PAMPs and DAMPs. SI leads to cell and tissue immunopathology contributing to hepatic and extrahepatic organ failure. Concomitantly, the course of ACLF is associated with a disproportio...

This study also identified the cardiac myocyte as a significant local source of BDNF, as cardiac myocyte-specific deletion of BDNF induced a similar cardiomyopathy phenotype. While these results do not exclude a role for other neurotrophins, particularly in injury states, they point to the requirement for continued, local synthesis of BDNF to maintain optimal cardiac function. A major, unresolved question relates to how the truncated TrkB isoform (TrkBT1) transduces the inotropic effects of BDNF, which will require additional study. A concurrent study evaluated the potential impact of the BDNF-mediated activation of the k...

In this study the effect of NMP perfusion fluid on survival, metabolism and function of thawed cryopreserved human (h)MSC and porcine (p)MSC in suspension conditions was studied. Suspension conditions reduced the viability of pMSC by 40% in both perfusion fluid and culture medium. Viability of hMSC was reduced by suspension conditions by 15% in perfusion fluid, whilst no differences were found in survival in culture medium. Under adherent conditions, survival of the cells was not affected by perfusion fluid. The perfusion fluid did not affect survival of fresh MSC in suspension compared to the control culture medium. The f...
