BACKGROUND: Implantable cardioverter defibrillators (ICDs) provide a significant mortality benefit for appropriately selected patients with advanced heart failure. ICDs are associated with a mortality benefit when used in patients with a pulsatile left ventricular assist device (LVAD). It is unclear whether patients with a continuous-flow LVAD (CF-LVAD) derive the same benefit. We sought to determine if the presence of an ICD provided a mortality benefit during CF-LVAD support as a bridge to transplantation...

BACKGROUND AND AIMS: Hypoxia inducible factor 1 alpha subunit (HIF1A) is a transcription factor that controls the cellular response to hypoxia and is activated in hepatocytes of patients with non-alcoholic fatty liver disease (NAFLD). NAFLD increases risk for cholesterol gallstone disease by unclear mechanisms. We studied the relationship between HIF1A and gallstone formation associated with liver steatosis. METHODS: We performed studies with mice with inducible disruption of Hif1a in hepatocytes, via a Cre adenoviral vector (iH-HIFKO mice), and mice without disruption of Hif1a (control mice)...

BACKGROUND & AIMS: Concurrent to development of more effective drugs for treatment of hepatitis C virus (HCV), infection, there has been an increase in the incidence of non-alcoholic fatty liver disease (NAFLD). Data indicate that liver transplantation prolongs survival times of patient with acute hepatitis associated with alcoholic liver disease (ALD). We compared data on disease prevalence in the population with data from liver transplantation waitlists to evaluate changes in the burden of liver disease in the United States...

This paper introduces a noise robust real time heart rate detection system from electrocardiogram (ECG) data. An online data acquisition system is developed to collect ECG signals from human subjects. Heart rate is detected using window-based autocorrelation peak localisation technique. A low-cost Arduino UNO board is used to implement the complete automated process. The performance of the system is compared with PC-based heart rate detection technique. Accuracy of the system is validated through simulated noisy ECG data with various levels of signal to noise ratio (SNR)...

Two types of Planecta™ ports are commonly used as sampling ports in blood pressure transducer kits: a flat-type port (FTP) and a port with a three-way stopcock (PTS). Recently, a new type of three-way stopcock (Marvelous™) has been released as a Planecta™ counterpart, but its effects on the frequency characteristics and reliability of blood pressure monitoring have not been investigated. We assessed the influence of the Marvelous™ stopcock on the frequency characteristics of the pressure transducer kit...

BACKGROUND: Donors are matched for weight in pediatric heart transplantation (PHT), yet age differences are not considered in this decision. In this study we attempt to identify the effect of age differences in weight-matched patients and the effect these differences have on post-transplant survival. METHODS: The United Network of Organ Sharing (UNOS) database was queried for the period from October 1987 to March 2014 for all pediatric heart transplant patients...

The use of the calculated panel reactive antibody (CPRA) value and the implementation of allocation points for sensitized candidates by the United Network for Organ Sharing (UNOS) have improved access to kidney transplantation for highly sensitized candidates (98% CPRA and above). Despite this, a large population of highly sensitized candidates remain awaiting transplantation. To better define this population, we propose the use of two refinements of the standard UNOS CPRA, the CPRA with decimals or CPRAd, and the likelihood of a compatible donor (LCD)...

Hormesis is a biological phenomenon, whereby exposure to low levels of toxic agents or conditions increases organismal viability. It thus represents a beneficial aspect of adaptive responses to harmful environmental stimuli. Here we show that hormesis effects induced in the parental generation can be passed on to the descendants in Caenorhabditis elegans. Animals subjected to various stressors during developmental stages exhibit increased resistance to oxidative stress and proteotoxicity. The increased resistance is transmitted to the subsequent generations grown under unstressed conditions through epigenetic alterations...

BACKGROUND AND AIM: The significance of examination time of esophagogastroduodenoscopy (EGD) for asymptomatic examinees is yet to be established. We aimed to clarify whether endoscopists who allot more examination time can detect higher numbers of neoplastic lesions among asymptomatic examinees. METHODS: We reviewed a database of consecutive examinees who underwent EGD in our hospital from April 2010 to September 2015. Staff endoscopists were classified into fast, moderate, and slow groups based on the mean examination time of EGD without a biopsy...

BACKGROUND: To maximize the benefit of lung transplantation, the effect of size mismatch on survival in lung transplant recipients with restrictive lung disease (RLD) was examined. METHODS: All single and bilateral RLD lung transplants from 1987-2011 in the UNOS Database were identified. Donor pTLC:Recipient pTLC ratio (pTLCr), quantified mismatch. pTLCr was segregated into 5 strata. A Cox proportional hazards model evaluated the association of pTLCr with mortality hazard...

The number of pancreas transplants performed in the United States stabilized over the last 3 years after nearly a decade of steady decline. Numbers of new additions to the list also stabilized during the same period. Notably, the persistent decline in pancreas after kidney transplants also seems to have abated, at least for now. The first full year of data after implementation of the new pancreas allocation system revealed no change in the distribution of organs between simultaneous pancreas-kidney (SPK) transplant and pancreas transplant alone...

 Typical antipsychotics are easily expressed as adverse events such as extrapyramidal symptom (EPS). On the other hand, incidence of adverse events due to atypical antipsychotics is low. Therefore, currently, atypical antipsychotics are widely used to treat schizophrenia. However, it has been reported that there is no difference in the frequency of EPS in atypical and typical antipsychotics. This study aimed to evaluate the expression profile of EPS in atypical and typical antipsychotics treatment using the Japanese Adverse Drug Event Report (JADER) database...

BACKGROUND: The role of implantable cardioverter defibrillator (ICD) in reducing mortality in patients with left ventricular assisted devices (LVADs) listed for heart transplant remains unclear. We therefore, sought to interrogate whether ICDs are associated with reduced mortality in patients with LVADs listed for heart transplantation. METHODS: We searched the United Network for Organ Sharing (UNOS) Registry for LVAD patients (age≥18years) with dilated cardiomyopathies listed for heart transplantation (2008-2015)...

BACKGROUND: As more patients achieve long-term survival, it has become important to understand mortality in LT recipients. METHODS: We conducted retrospective reviews of long-term outcome in two adult LT cohorts: 85,031 in the UNOS database and 1,458 transplanted at the University of Wisconsin (UW). RESULTS: During median follow-up of 3.2 years (UNOS); and 6.6 years (UW), 35.1% of UNOS patients and 44.2% of UW patients died. 43.1% of all UNOS deaths occurred in year one compared to 25...

UNOS recommends that fellowship-trained surgeons participate in 15 LDN to be considered proficient. ASTS mandates 12 LDN during abdominal transplant surgery fellowship (ATSF). We performed a retrospective intraoperative case analysis to create a risk-adjusted cumulative summation (RACUSUM) model to assess the learning curve (LC) of novice TSF (nTSF). Between January 2000 and December 2014, 30 nTSF rotated on the Organ Procurement Rotation (OPR) of our ASTS-approved ATSF. Measures of surgical performance included: 1) intraoperative time (ORT), 2) estimated blood loss (EBL), and 3) incidence of intraoperative complications (IOC)...

OBJECTIVES: The optimal antimicrobial treatment duration for patients with acute cholangitis with bacteremia remains unknown. The updated Tokyo guidelines of 2013 recommend a minimum duration of 2 weeks only when bacteremia with Gram-positive cocci is present. Since May 2013, a shorter antimicrobial treatment duration of under 2 weeks has been implemented at the authors' institution for acute cholangitis with Gram-negative bacillary bacteremia. The aim of the present study was to validate this modified practice...

PURPOSE OF REVIEW: Donation after cardiac death is associated with many problems including ischemic injury, high rates of delayed allograft function, prolonged time to asystole, and frequent organ discard. Imminent death donation (IDD) has been proposed as a separate category of organ donation: distinct from living donation and donation after cardiac death. RECENT FINDINGS: A protocol for IDD was developed at Rhode Island Hospital and published in the ethics literature...

All extant lamprey karyotypes are characterized by almost all dot-shaped microchromosomes. To understand the molecular basis of chromosome structure in lampreys, we performed chromosome C-banding and silver staining and chromosome mapping of the 18S-28S and 5S ribosomal RNA (rRNA) genes and telomeric TTAGGG repeats in the Arctic lamprey (Lethenteron camtschaticum). In addition, we cloned chromosome site-specific repetitive DNA sequences and characterized them by nucleotide sequencing, chromosome in situ hybridization, and filter hybridization...

There has been increasing concern in the kidney transplant community about the declining use of expanded criteria donors (ECD) despite improvement in survival and quality of life. The recent introduction of the Kidney Donor Profile Index (KDPI), which provides a more granular characterization of donor quality, was expected to increase utilization of marginal kidneys and decrease the discard rates. However, trends and practice patterns of ECD kidney utilization on a national level based on donor organ quality as per KDPI are not well known...
