BACKGROUND & AIMS: Oral direct-acting antivirals (DAAs) for hepatitis C virus (HCV) treatment offer new hope to both pre- and post-liver transplant (LT) patients. However, whether to treat HCV patients pre- versus post-LT is not clear, as treatment can improve liver function but could reduce the chance of receiving a LT while on the waiting list. Our objective was to evaluate the cost-effectiveness of pre-LT versus post-LT HCV treatment with oral DAAs in decompensated cirrhotic patients on the LT waiting list...

Introducción: la adolescencia es un periodo vulnerable para padecer trastornos de la conducta alimentaria (TCA) como la anorexia y la bulimia nerviosas. La insatisfacción corporal, uno de los factores precipitantes de los TCA, conduce a las adolescentes a la búsqueda de información sobre dietas en internet. En este contexto, las páginas pro-Ana (proanorexia) y pro-Mía (probulimia) difunden contenidos altamente perjudiciales para la salud relacionados con la pérdida de peso y los TCA.Objetivos: en el presente trabajo se analizan la cantidad, el posicionamiento, la calidad y la difusión de las páginas pro-Ana y pro-Mía...

BACKGROUND: There are sex differences in mortality while awaiting heart transplantation, and the reason remains unclear. METHODS AND RESULTS: We included all adults in the Scientific Registry of Transplant Recipients placed on the heart transplant active waitlist from 2004 to 2015. The primary end point was all-cause mortality. Multivariable Cox proportional hazards models were performed to evaluate survival by United Network for Organ Sharing (UNOS) status at the time of listing...

Cynomolgus monkey cytochrome P450 2C9 (formerly known as P450 2C43) variation was reportedly associated with metabolic clearance of the antiretroviral drug efavirenz in vivo (of three wild-type, one heterozygote, and two homozygote animals), being unlikely in the case of human P450 2B6-dependent efavirenz clearance. In this study, the liver microsomal elimination rates of efavirenz for the same individual animals previously treated with intravenous/oral administrations of efavirenz showed significant reductions associated with the P450 2C9 p...

AIM: Geographic disparities persist in the U.S. despite locoregional organ sharing policies. The impact of national organ sharing policies on waiting-list mortality on a regional basis remains unknown. METHODS: Data on all adult liver transplants between February 1, 2002 and March 31, 2015 were obtained from UNOS/OPTN. Multivariable Cox proportional hazards models were constructed in a time-to-event analysis to estimate waiting-list mortality for the pre- and post-Share35 eras...

BACKGROUND AND PURPOSE: Optimal thresholds for ischemic penumbra detected by CT perfusion (CTP) in patients with acute ischemic stroke (AIS) have not been elucidated. In this study we investigated optimal thresholds for salvageable ischemic penumbra and the risk of hemorrhagic transformation (HT). METHODS: A total of 156 consecutive patients with AIS treated with mechanical thrombectomy (MT) at our hospital were enrolled. Absolute (a) and relative (r) CTP parameters including cerebral blood flow (aCBF and rCBF), cerebral blood volume (aCBV and rCBV), and mean transit time (aMTT and rMTT) were evaluated for their value in detecting ischemic penumbra in each of seven arbitrary regions of interest defined by the major supplying blood vessel...

We reported that current assignment of HLA-DQ is a barrier to organ allocation. Here we simulated the impact of incorporating HLA-DQ antigens and antibodies as A/B and αβ allelic variants, respectively, on calculated PRA and probability of finding potential compatible donors (PCD). A cohort of 1224 donors and 2075 sensitized candidates was analyzed using HLA-DQαβ allelic (study) versus serologic (current practice) nomenclature. A significant (p<10(-4) ) decrease in cPRA was observed with higher impact for male versus female, and first transplant versus retransplant (p<10(-4) ), affecting mostly patients with moderate cPRA (30-80%)...

Phosphopantetheine transferases (PPTases) can be used to efficiently prepare site-specific antibody-drug conjugates (ADCs) by enzymatically coupling coenzyme A (CoA)-linker payloads to 11-12 amino acid peptide substrates inserted into antibodies. Here, a two-step strategy is established wherein in a first step, CoA analogs with various bioorthogonal reactivities are enzymatically installed on the antibody for chemical conjugation with a cytotoxic payload in a second step. Because of the high structural similarity of these CoA analogs to the natural PPTase substrate CoA-SH, the first step proceeds very efficiently and enables the use of peptide tags as short as 6 amino acids compared to the 11-12 amino acids required for efficient one-step coupling of the payload molecule...

Este año hemos elegido como tema central del curso el "Abordaje nutricional del paciente crónico complejo", por entender que se trata de uno de los retos más importantes que tenemos los profesionales sanitarios que formamos parte de un sistema sanitario que tiene amenazada su sostenibilidad.El envejecimiento de la población es una realidad de cifras abrumadoras. Como lo es también el aumento de prevalencia de pacientes crónicos. En 2016, el 19,9% de la población española tenía 65 años o más y en 2050 se estima que un 30%-35% será mayor de 65 años y habrá algo más de 4 millones de octogenarios...

Strawberry fruit contain the allergenic Fra a proteins, members of the pathogenesis-related 10 protein family that causes oral allergic syndrome symptoms. Fra a proteins are involved in the flavonoid biosynthesis pathway, which might be important for color development in fruits. Auxin is an important plant hormone in strawberry fruit that controls fruit fleshiness and ripening. In this study, we treated strawberry fruits with exogenous auxin or auxin inhibitors at pre- and post-harvest stages, and analyzed Fra a transcriptional and translational expression levels during fruit development by real-time PCR and immunoblotting...

The theory of retrograde menstruation as aetiopathogenesis of endometriosis formulated by John Sampson in 1927 shows clear shortcomings: this does not explain why retrograde menstruation is a physiological process that affects 90% of women, while endometriosis occurs in only 10% of cases; it also does not explain the endometriotic foci distant from the pelvis, nor explains the cases of endometriosis in male patients. The immunological alterations of the peritoneal fluid explains the effects of disease, such as the inhibition of the physiological processes of cytolysis, but does not explain the cause...

High serum uric acid (UA) level has been assumed to be a risk factor for left ventricular (LV) dysfunction; however, the precise relationship between these conditions has not been fully examined because many confounding factors are associated with UA level. We herein examined the precise relationship by proposing structural equation models. The study population consisted of 1432 cases with ischemic heart disease who underwent cardiac catheterization. Multiple regression analyses and covariance structure analyses were performed to elucidate the cause-and-effect relationship between UA level and LV ejection fraction (LVEF)...

BACKGROUND AND OBJECTIVES: The calculated panel reactive of antibodies (cPRAs) necessary for kidney donor-pair exchange and highly sensitized programs are estimated using different panel reactive antibody (PRA) calculators based on big enough samples in Eurotransplant (EUTR), United Network for Organ Sharing (UNOS), and Canadian Transplant Registry (CTR) websites. However, those calculators can vary depending on the ethnic they are applied. Here, we develop a PRA calculator used in the Spanish Program of Transplant Access for Highly Sensitized patients (PATHI) and validate it with EUTR, UNOS, and CTR calculators...
