Chronic renal, liver and heart failure in children associates with multiple skeletal complications. Increased fracture incidence often persists after transplantation and could be related to alterations in bone material properties. In the present cohort study we evaluated bone mineralization density distribution (BMDD) by quantitative backscattered electron imaging (qBEI) in 23 pediatric solid organ allograft recipients with suspected osteoporosis. We measured BMDD in the entire cross-sectional area of transiliac bone biopsies obtained from kidney (n = 9), liver (n = 9) and heart (n = 5) transplant recipients (aged 7...

One prominent cause of implant failure is infection, therefore research is focusing on developing surface coatings that render the surface resistant to colonization by micro-organisms. Permanently attached coatings of antimicrobial molecules are of particular interest because of the reduced cytoxicity and lower risk of developing resistance compared to controlled release coatings. In this study, we focus on the chemical grafting of bioactive molecules on titanium. To concentrate the molecules at the metallic implant surface, we propose electrophoretic deposition (EPD) applying alternating current (AC) signals with an asymmetrical wave shape...

The use of extended criteria donors who might have previously been deemed unsuitable is an option to increase the organ supply for transplantation. This report presents a pediatric case of a successful liver transplantation from a donor with β-thalassemia intermedia. A patient, 6-year-old female, with a diagnosis of cryptogenic liver cirrhosis underwent deceased donor liver transplantation from a thalassemic donor. Extreme hyperferritinemia was detected shortly after transplantation. The most probable cause of hyperferritinemia was iron overload secondary to transplantation of a hemosiderotic liver...

BACKGROUND & AIMS: Current guidelines discourage renal replacement therapy (RRT) in critically ill cirrhotics in the lack of liver transplant (LT) options. This study aimed to identify patients who benefit from RRT in the short and long-term. METHODS: Critically ill cirrhotics were included over a time period of 6 years (y) and followed for at least 1y. CLIF-C ACLF, CLIF-SOFA, SOFA and MELD scores on admission, 24h prior to RRT, 24h and 48h after start of RRT were analyzed for their predictive value of ICU-mortality...

Staphylococcus hyicus is one of the opportunistic pathogens that cause infections to animals. Early studies have demonstrated that S. hyicus is the causative agents of exudative epidermitis in pigs, arthritis in horses and chicken, mastitis in cow, and bacteremia, sepsis and multiple organ failure in humans. Here, we report the isolation and identification of a representative S. hyicus isolate, named JLHN15, from a pig farm with a disease characterized by bacteremia, suppurative pneumonia and fibrinous pericarditis...

Acute-on-chronic liver failure (ACLF) is an emerging clinical syndrome in patients with underlying liver disease that is usually triggered by one or multiple insults and characterized by progressive hepatic and nonhepatic organ failure, a significant risk of infections, and high short-term mortality rates. Despite our incomplete understanding of the underlying pathophysiology, ACLF requires timely diagnostic and therapeutic measures aiming at the identification and elimination of causative factors as well as the prevention of complications to improve the prognosis of affected patients...

The emerging field of regenerative medicine offers innovative methods of cell therapy and tissue/organ engineering as a novel approach to liver disease treatment. The ultimate scientific foundation of both cell therapy of liver diseases and liver tissue and organ engineering is delivered by the in-depth studies of the cellular and molecular mechanisms of liver regeneration. The cellular mechanisms of the homeostatic and injury-induced liver regeneration are unique. Restoration of the mass of liver parenchyma is achieved by compensatory hypertrophy and hyperplasia of the differentiated parenchymal cells, hepatocytes, while expansion and differentiation of the resident stem/progenitor cells play a minor or negligible role...

[Purpose] Exercise therapy during dialysis is currently being recommended since it is easy for patients to follow and results in high participation rates. In this study, this therapy was performed for elderly patients undergoing maintenance dialysis, and its effects were examined. [Subjects and Methods] Seven elderly patients (age: 70.6 ± 4.4) with chronic renal failure, who were able to perform exercises during maintenance dialysis, received the exercise therapy 2 or 3 times weekly for 3 months. Lower-limb muscle strength as well as the standardized dialysis dose (Kt/V) was measured before and after intervention...

Bacterial sepsis involves a complex interaction between the host immune response and bacterial lipopolysaccharides (LPS). LPS binds Toll-like receptor (TLR) 4, which leads to the release of pro-inflammatory cytokines that are essential for a potent innate immune response against pathogens. The innate immune system is tightly regulated as excessive inflammation can lead to organ failure and death. MicroRNAs have recently emerged as important regulators of the innate immune system. Here, we determined the function of miR-718, which is conserved across mammals and overlaps with the 5 UTR of the Interleukin-1 Receptor-Associated Kinase (IRAK1) gene...

BACKGROUND: Liver failure (LF) is associated with prolonged hospital stay, increased cost and substantial mortality. Due to the limited number of donor organs, extracorporeal liver support is suggested as an appealing concept to "bridge to transplant" or to avoid transplant in case of recovery. ADVanced Organ Support (ADVOS) is a new type of albumin dialysis, that provides rapid regeneration of toxin-binding albumin by two purification circuits altering the binding capacities of albumin by biochemical (changing of pH) and physical (changing of temperature) modulation of the dialysate...

Drug-induced liver injury (DILI) is the most common reason for failures during the drug development process and for safety-related withdrawal of drugs from the pharmaceutical market. Therefore, having tools and techniques that can detect hepatotoxic properties in drug candidates at an early discovery stage is highly desirable. In this study, cell imaging counting was used to measure in a fast, straightforward, and unbiased way the effect of paracetamol and tetracycline, (compounds known to cause hepatotoxicity in humans) on the amount of DsRed-labeled hepatocytes recovered by protease digestion from Tg(fabp10a:DsRed) transgenic zebrafish...

Massive pulmonary embolism (PE) refers to large emboli that cause hemodynamic instability, right ventricular failure, and circulatory collapse. According to the 2016 ACCP Antithrombotic Guidelines, therapy for massive PE should include systemic thrombolytic therapy in conjunction with anticoagulation and supportive care. However, in patients with a contraindication to systemic thrombolytics or in those who fail the above interventions, extracorporeal membrane oxygenation (ECMO) and/or surgical embolectomy may be used to improve oxygenation, achieve hemodynamic stability, and successfully treat massive PE...

Heart failure is a growing epidemic in the United States and throughout the world. The utilization of continuous-flow left ventricular assist devices (LVADs) has greatly increased over the last decade. In addition, a limited supply of organ donors has led to a rise in the use, and duration, of LVADs for destination therapy. The increased use of LVAD therapy has led to the observation of mechanical complications such as device thrombosis, de novo aortic insufficiency, and outflow graft stenosis, all of which are associated with prolonged LVAD support...

Diseases leading to critical illness induce proteolysis resulting in muscle wasting and negative nitrogen balance. Muscle wasting has been associated with poor intensive care unit (ICU)-related outcomes, including an increased risk for mortality. Acute kidney injury (AKI) represents a common organ dysfunction associated with ICU-related disorders, such as sepsis, trauma, and respiratory failure. AKI and renal replacement therapy lead to amino acid loss. Decompensated liver cirrhosis (DLC) and acute liver failure (ALF) represent more severe forms of liver dysfunction leading to ICU admission...

REVIEW
Katelyn R Ludwig, Amanda B Hummon
Sepsis is a serious medical condition that occurs in 30% of patients in intensive care units (ICUs). Early detection of sepsis is key to prevent its progression to severe sepsis and septic shock, which can cause organ failure and death. Diagnostic criteria for sepsis are nonspecific and hinder a timely diagnosis in patients. Therefore, there is currently a large effort to detect biomarkers that can aid physicians in the diagnosis and prognosis of sepsis. Mass spectrometry is often the method of choice to detect metabolomic and proteomic changes that occur during sepsis progression...
