BACKGROUND: Our objective was to determine whether the choice of a HeartWare HVAD as opposed to a Heartmate II left ventricular assist device (HMII LVAD), impacts survival after heart transplantation after controlling for patient, donor, and center characteristics. METHODS: We queried the United Network for Organ Sharing (UNOS) database, which has recently made pretransplantation device duration available, for all adult patients undergoing bridge to transplantation (BTT) between January 2011 and March 2016...

Liver failure is a disease with a high mortality rate. Often liver transplantation is the sole therapeutic option. On the one hand, liver support systems probably support the liver to allow regeneration, on the other hand they are an option to bridge for transplantation. This article gives an overview on the clinically used liver assist devices (molecular adsorbent recirculating system [MARS], Prometheus system, single-pass albumin dialysis [SPAD], plasmapheresis) and discusses the applications in liver failure...

 Amanita phalloides is the most relevant mushroom intoxication leading to acute liver failure. The two principal groups of toxins, the amatoxins and the phallotoxins, are small oligopeptides highly resistant to chemical and physical influences. The amatoxins inhibit eukaryotic RNA polymerase II causing transcription arrest affecting mainly metabolically highly active cells like hepatocytes and renal cells. The clinically most characteristic symptom is a 6-40 h lag phase before onset of gastrointestinal symptoms and the rapid progression of acute liver failure leading to multi-organ failure and death within a week if left untreated...

BACKGROUND: In children acute liver failure is a rare but life-threatening condition from which two-thirds do not recover with supportive therapy. Treatment is limited by the availability of liver transplants. Molecular adsorbent recirculating system (MARS) dialysis is a bridge to transplantation that enhances the chances of survival during the waiting period for a transplant, although it cannot improve survival. Open albumin dialysis (OPAL) is a new mode of albumin dialysis developed to further improve dialysis efficiency...

Dietary therapy represents an important tool in the management of chronic kidney disease (CKD), mainly through a balanced reduction of protein intake aimed at giving the remnant nephrons in damaged kidneys a "functional rest". While dialysis, transplantation, and pharmacological therapies are usually seen as "high tech" medicine, non pharmacological interventions, including diets, are frequently considered lifestyle-complementary treatments. Diet is one of the oldest CKD treatments, and it is usually considered a part of "mainstream" management...

UNLABELLED: The Italian Registry of Dialysis and Transplantation (RIDT) has recently resumed the collection of data of patients on RRT in Italy. Data were requested to Regional Registries for the years 2011-2013 and they contributed according to their possibilities. Eighteen Regions or autonomous Provinces provided data with various degrees of completeness and this made possible to bridge the gap between the current and the previous census (referring to 2010). RESULTS: Incidencedata were associated to a sample with a coverage of 77% of the national population (46/60 million inhabitants)...

BACKGROUND: The management of antithrombotic agents for endoscopic procedures has recently focused on preventing periprocedural thrombosis in Western countries. However, this focus on shorter cessation of antithrombotic agents needs to be examined for its implications for post-procedural bleeding, with potential risk factors for such bleeding clarified in real-world clinical settings in Japan. METHODS: A Sapporo consensus group convened and developed a consensus document on the criteria for cessation of antithrombotic agents...

Central venous catheters are a popular choice for the initiation of hemodialysis or for bridging between different types of access. Despite this, they have many drawbacks including a high morbidity from thrombosis and infection. Advances in technology have allowed placement of these lines relatively safely, and national guidelines have been established to help prevent complications. There is an established algorithm for location and technique for placement that minimizes harm to the patient; however, there are significant short- and long-term complications that proceduralists who place catheters should be able to recognize and manage...

Consecutive two-dimensional frameworks comprised of molecular or cluster building blocks in large area represent ideal candidates for membranes sieving molecules and nano-objects, but challenges still remain in methodology and practical preparation. Here we exploit a new strategy to build soft single-layer ionic organic-inorganic frameworks via electrostatic interaction without preferential binding direction in water. Upon consideration of steric effect and additional interaction, polyanionic clusters as connection nodes and cationic pseudorotaxanes acting as bridging monomers connect with each other to form a single-layer ionic self-assembled framework with 1...

The number of patients developing liver failure; acute on chronic liver failure and acute liver failure continues to increase, along with the demand for donor livers for transplantation. As such there is a clinical need to develop effective extracorporeal devices to support patients with acute liver failure or acute-on-chronic liver failure to allow time for hepatocyte regeneration, and so avoiding the need for liver transplantation, or to bridge the patient to liver transplantation, and also potentially to provide symptomatic relief for patients with cirrhosis not suitable for transplantation...

The aim of this study was to evaluate clinical outcomes after left ventricular assist device (LVAD) implantation in patients with severe pre-LVAD renal dysfunction (RD). The cohort of 165 consecutive patients implanted with HeartMate II LVADs was divided into two groups: 1) baseline glomerular filtration rate (bGFR) ≤ 40 ml/min/1.73 m (n = 30), and 2) GFR > 40 ml/min/1.73 m (n = 135). In both groups, GFR increased significantly at 1 month and then declined, remaining higher than the pre-LVAD level in the bGFR ≤ 40 group and returning back to the pre-LVAD level in the bGFR > 40 group by 1 year post-LVAD follow-up...

The proportion of heart transplant recipients bridged with durable, intracorporeal left ventricular assist devices (dLVADs) has dramatically increased; however, concern exists regarding obligate repeat sternotomy, increased bleeding risk because of anticoagulation and acquired von Willebrand disease, and increased rates of allosensitization. Whether dLVAD patients have impaired posttransplant outcomes compared with equivalent patients with less invasive intraaortic balloon pump counterpulsation (IABP) at the time of transplant is unknown...

INTRODUCTION: Mechanical circulatory support (MCS) is a recognised method of treatment for patients with end-stage chronic or acute heart failure. The POLCAS pulsatile-flow system has been used in our institution for 15 years. Currently, it is being widely replaced by continuous-flow mechanical circulatory support equipment of the second and third generations (HeartMateII, HeartWare). The MCS presented in this study is associated with a significant risk of complications and its use is increasingly considered controversial...

PURPOSE OF REVIEW: There is growing acknowledgement that engaging patients to identify their research priorities is important. Using a case study of patients on or nearing dialysis, we sought to assess the extent to which recently completed and ongoing clinical research was consistent with priorities identified by patients, caregivers, and clinicians. SOURCES OF INFORMATION: Over a 4-year sampling frame (January 2010 to December 2013), we systematically searched the medical literature (top 5 nephrology and top 10 general medicine journals accessed through MEDLINE via Ovid), international randomized controlled trial (RCT) registries, and national government and kidney research funding organizations (Canada, U...

Albumin dialysis is the best-studied extracorporeal nonbiologic liver support system as a bridge or destination therapy for patients with liver failure awaiting liver transplantation or recovery of liver function. We performed a systematic review to examine the efficacy and safety of 3 albumin dialysis systems (molecular adsorbent recirculating system [MARS], fractionated plasma separation, adsorption and hemodialysis [Prometheus system], and single-pass albumin dialysis) in randomized trials for supportive treatment of liver failure...

Refractory ventricular arrhythmia is a serious problem in acute myocardial infarction (AMI), with an extremely high mortality rate and limited effective treatment. Extracorporeal membrane oxygenation (ECMO) is useful to rescue patients with cardiopulmonary collapse. However, little is known about whether ECMO is a potential rescue technique for patients with refractory ventricular arrhythmia in AMI.We retrospectively analyzed prospectively collected data on patients with AMI and refractory ventricular arrhythmia who underwent ECMO as rescue therapy and the bridge to revascularization from February 2001 to January 2013...
