BACKGROUND: Identification of strategies to improve organ donor utilization remains imperative. Despite the association between hospital volume and outcomes for many common disease processes, there have been no studies to assess the impact of organ donor hospital volume on organ yield. STUDY DESIGN: A prospective observational study of all deceased organ donors managed by ten OPOs across UNOS Regions 4, 5, and 6 was conducted from February 2012-June 2015. In order to study the impact of hospital volume on organ yield, each donor was placed into a hospital volume quartile based on the number of donors managed by their hospital...

Dietary restriction regimens lead to enhanced stress resistance and extended life span in many species through the regulation of fasting and/or diet-responsive mechanisms. The fasting stimulus is perceived by sensory neurons and causes behavioral and metabolic adaptations. Octopamine (OA), one of the Caenorhabditis elegans neurotransmitters, is involved in behavioral adaptations, and its levels are increased under fasting conditions. However, it remains largely unknown how OA contributes to the fasting responses...

Immunotherapies based on immune checkpoint blockade are highly effective in a subset of patients. An ongoing challenge is the identification of biomarkers that predict which patients will benefit from these therapies. Aneuploidy, also known as somatic copy number alterations (SCNAs), is widespread in cancer and is posited to drive tumorigenesis. Analyzing 12 human cancer types, we find that, for most, highly aneuploid tumors show reduced expression of markers of cytotoxic infiltrating immune cells, especially CD8(+) T cells, and increased expression of cell proliferation markers...

We investigated the clinical course of patients after cessation of long-term successful hormone monotherapyfor prostate cancer. Studysubjects were ten patients with prostate cancer (localized prostate cancer ; n=8, prostate cancer with bone metastasis ; n=2), who had hormone monotherapyfor over seven years, showed no signs of recurrence, and maintained prostatic-specific antigen (PSA) levels of less than the detection sensitivitylimit (<0.01 ng/ml). The mean duration of hormone therapywas 101.1 months, and the mean duration of follow-up observation from cessation of the therapywas 31...

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: 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...
