We aimed to assess the incidence of HAT over three eras following implementation of microvascular techniques and a customized anticoagulation protocol in a predominantly cadaveric split liver transplant program. We retrospectively reviewed pediatric liver transplants performed between April 1986 and 2016 and analyzed the incidence HAT over three eras. In E1, 1986-2008, each patient received a standard dose of 5 U/kg/h of heparin and coagulation profiles normalized passively. In E2, 2008-2012, microvascular techniques were introduced...

PURPOSE: Little is known about age-related differences in risk factors for cigarette smoking initiation. We identified predictors of initiation in early, middle, and late adolescence from among sociodemographic factors, indicators of smoking in the social environment, psychological characteristics, lifestyle indicators, and perceived need for cigarettes. METHODS: Data were drawn from a longitudinal study of 1,801 children recruited at age 10-11 years from 29 elementary schools in Montreal, Canada...

Aboriginal Australians represent one of the longest continuous cultural complexes known. Archaeological evidence indicates that Australia and New Guinea were initially settled approximately 50 thousand years ago (ka); however, little is known about the processes underlying the enormous linguistic and phenotypic diversity within Australia. Here we report 111 mitochondrial genomes (mitogenomes) from historical Aboriginal Australian hair samples, whose origins enable us to reconstruct Australian phylogeographic history before European settlement...

Solubility parameter based methods have long been a valuable tool for solvent formulation and selection. Of these methods, the MOdified Separation of Cohesive Energy Density (MOSCED) has recently been shown to correlate well the equilibrium solubility of multifunctional non-electrolyte solids. However, before it can be applied to a novel solute, a limited amount of reference solubility data is required to regress the necessary MOSCED parameters. Here we demonstrate for the solutes methylparaben, ethylparaben, propylparaben, butylparaben, lidocaine and ephedrine how conventional molecular simulation free energy calculations or electronic structure calculations in a continuum solvent, here the SMD or SM8 solvation model, can instead be used to generate the necessary reference data, resulting in a predictive flavor of MOSCED...

OBJECTIVES: Most infants with biliary atresia (BA) require liver transplantation (LT) after hepatoportoenterostomy (HPE), including those who initially clear jaundice. The aim of the present study was to identify clinical and routine laboratory factors in infants with BA post-HPE that predict native liver survival at 2 years. METHODS: A retrospective cohort study was conducted in 217 patients with BA undergoing HPE in Sydney, Australia and Toronto, Canada between January 1986 and July 2009...

BACKGROUND: In a post hoc analysis of the ENIGMA-II trial, we sought to determine whether intraoperative dexamethasone was associated with adverse safety outcomes. METHODS: Inverse probability weighting with estimated propensity scores was used to determine the association of dexamethasone administration with postoperative infection, quality of recovery, and adverse safety outcomes for 5499 of the 7112 non-cardiac surgery subjects enrolled in ENIGMA-II. RESULTS: Dexamethasone was administered to 2178 (40%) of the 5499 subjects included in this analysis and was not associated with wound infection [189 (8...

The brain has a tightly regulated environment that protects neurons and limits inflammation, designated "immune privilege." However, there is not an absolute lack of an immune response. We tested the ability of the brain to initiate an innate immune response to a virus, which was directly injected into the brain parenchyma, and to determine whether this response could limit viral spread. We injected vesicular stomatitis virus (VSV), a transsynaptic tracer, or naturally occurring VSV-derived defective interfering particles (DIPs), into the caudate-putamen (CP) and scored for an innate immune response and inhibition of virus spread...

BACKGROUND: Intestinal failure-associated liver disease (IFALD) can be treated with parenteral fish oil (FO) monotherapy, but practitioners have raised concerns about a potential bleeding risk. This study aims to describe the incidence of clinically significant post-procedural bleeding (CSPPB) in children receiving FO monotherapy. METHODS: A retrospective chart review was performed on patients at our institution treated with intravenous FO for IFALD. CSPPB was defined as bleeding leading to re-operation, transfer to the intensive care unit, re-admission, or death, up to one month after any invasive procedure...

Myeloid-derived suppressor cells (MDSC) contribute to an immunosuppressive network that drives cancer escape by disabling T cell adaptive immunity. The prevailing view is that MDSC-mediated immunosuppression is restricted to tissues where MDSC co-mingle with T cells. Here we show that splenic or, unexpectedly, blood-borne MDSC execute far-reaching immune suppression by reducing expression of the L-selectin lymph node (LN) homing receptor on naïve T and B cells. MDSC-induced L-selectin loss occurs through a contact-dependent, post-transcriptional mechanism that is independent of the major L-selectin sheddase, ADAM17, but results in significant elevation of circulating L-selectin in tumor-bearing mice...

In the fall of 2014, an international news agency reported that patients suffering from Ebola virus disease (EVD) in Liberia were treated successfully with lamivudine, an antiviral drug used to treat human immunodeficiency virus-1 and hepatitis B virus infections. According to the report, 13 out of 15 patients treated with lamivudine survived and were declared free from Ebola virus disease. In this study, the anti-Ebola virus (EBOV) activity of lamivudine and another antiretroviral, zidovudine, were evaluated in a diverse set of cell lines against two variants of wild-type EBOV...

BACKGROUND: The treatment goal for recurrent malignant gliomas centers on disease stabilization while minimizing therapy-related side effects. Metronomic dosing of cytotoxic chemotherapy has emerged as a promising option to achieve this objective. METHODS: This phase I study was performed using metronomic temozolomide (mTMZ) at 25 or 50 mg/m(2)/day continuously in 42-day cycles. Correlative studies were incorporated using arterial spin labeling MRI to assess tumor blood flow, analysis of matrix metalloproteinase-2 (MMP-2) and MMP-9 activities in the cerebrospinal fluid (CSF) as surrogates for tumor angiogenesis and invasion, as well as determination of CSF soluble interleukin-2 receptor alpha (sIL-2Rα) levels as a marker of immune modulation...

The entry of secondary invaders into, or their expansion within, native communities is contingent on the changes wrought by other (primary) invaders. When primary invaders have altered more than one property of the recipient community, standard descriptive and modeling approaches only provide a best guess of the mechanism permitting the secondary invasion. In rainforest on Christmas Island, we conducted a manipulative field experiment to determine the mechanism of invasion success for a community of land snails dominated by non-native species...

INTRODUCTION: More cigarette smokers report poor sleep quality than non-smokers, but the association between nicotine dependence (ND) and sleep quality has not been well-characterized. The objective of this study was to describe the associations among frequency and intensity of cigarette smoking, ND symptoms, and sleep quality in young adults. METHODS: Data on past-year smoking frequency, number of cigarettes smoked in the past month, five ND indicators (i.e., withdrawal, craving, self-medication symptoms, mFTQ, ICD-10 criteria for tobacco dependence), and sleep quality (measured with the Pittsburgh Sleep Quality Index (PSQI)) were collected in 2011-12 in self-report questionnaires completed by 405 young adult smokers (mean age 24 (0...

INTRODUCTION: Secondhand smoke (SHS) can quickly attain high concentrations in cars, posing health risks to passengers and especially to children. This paper assesses whether there are social disparities in children's exposure to SHS in privately owned vehicles. METHODS: On weekday mornings and afternoons from September to November 2011, trained observers were stationed at 100 selected street intersections in Montreal, Canada. For each car transporting at least one passenger aged 0-15 years travelling through the intersection, observers recorded the estimated age of the youngest child in the car, whether any occupant was smoking and the licence plate number of the car...

Cerebrofacial arteriovenous metameric syndrome (CAMS) is a recent classification of vascular malformations that encompasses a spectrum of phenotypic expression involving arteriovenous malformations (AVMs) of the cerebral, orbital, and facial region. Recognizing the embryologic basis of CAMS is important for diagnosing other AVMs along the same metameric level. Visual loss is the most common presentation prompting ophthalmologic evaluation followed by neuroimaging. We present two pediatric patients with ipsilateral optic nerve and chiasmal AVMs without cutaneous manifestations, characteristic of CAMS 2...

BACKGROUND: Diabetic Charcot neuroarthropathy (DCN) is a devastating complication for people with diabetes mellitus. The failure to diagnose DCN and institute treatment in the acute phase leads to permanent deformity and significant morbidity. There is a paucity of data on the prevalence and characteristics of patients who have developed this complication of diabetes. AIMS: To determine the prevalence, clinical characteristics and outcomes of patients with DCN from 2006 to 2012...

PURPOSE: The majority of people with multiple sclerosis (pwMS) initially present with discreet periods of relapses followed by partial remission of symptoms (RRMS). Over time, most pwMS transition to secondary progressive MS (SPMS), characterized by a gradual accumulation of disability. This study aimed to explore the experiences, coping and needs associated with transitioning from RRMS to SPMS. METHOD: Data were collected via semi-structured interviews with nine pwMS and seven specialist MS health professionals (HPs)...
