Palytoxin Poisoning via Inhalation in Pediatric Siblings

Introduction: Several cases of palytoxin poisoning have occurred during cleaning of aquariums. Case Report: We report a case of palytoxin inhalational toxicity in pediatric siblings following secondary exposure to vapors from cleaning of an aquarium containing Zoanthids. Symptoms included fever, tachycardia, leukocytosis and elevated lactic dehydrogenase. Both patients received supportive treatment in the pediatric intensive care unit and were discharged after 48 hours. Symptoms also occurred in children’s parents including cleaning attendant. Conclusion: Herein, we present a rare case of inhalational toxicity from palytoxin

Cyclophosphamide for Suspected Primary Angiitis of the Central Nervous System in a Patient with Human Immunodeficiency Virus: A Case Report

Introduction: Central nervous system (CNS) vasculitis is rare, including in human immunodeficiency virus (HIV), occurring in less than 1% of patients. Systemic vasculitis affecting the CNS is termed secondary CNS vasculitis, whereas primary CNS vasculitis, referred to as primary angiitis of the CNS (PACNS) refers to an extremely rare disease specifically confined to the CNS. Only some cases of PACNS in HIV patients have been reported in literature. Case Report: We report a case of a 46-year-old female with HIV who developed probable primary CNS vasculitis, which was treated with intravenous cyclophosphamide and glucocorticoids for both induction and maintenance. A systematic literature review regarding PACNS and its therapeutic management is presented in this report. There were no clinical trials for PACNS. Based on the American Academy of Neurology (AAN) classes of evidence for therapeutic effectiveness, most data is of intermediate or weak strength. Conclusion: This case highlights diagnostic and clinical features of PACNS and provides an overview of the current literature regarding pharmacotherapy. Further case reports and additional studies are needed

Development of a Risk Assessment Tool for Falls Prevention in Hospital Inpatients Based on the Medication Appropriateness Index (MAI) and Modified Beer's Criteria

Medication review is an essential component of comprehensive falls assessment. A medication review by pharmacists can assist to identify and notify prescribers of medications that require adjustment or discontinuation. Beers Criteria and the Medication Assessment Index (MAI) are explicit and implicit inappropriate prescribing (IP) tools, respectively. While the Beers Criteria has been applied to falls prevention, the MAI has not. Developing alternative falls prevention tools has been spurned by both the desire to overcome limitations of the Beers Criteria, coupled with the need for implicit criteria which includes consideration for patient äóñspecific clinical judgement. A literature search and review of the Beers Criteria and MAI tools revealed advantages and disadvantages of each. Using combined explicit/implicit falls assessment criteria using both the Beers Criteria and MAI as a framework, a falls specific inappropriate prescribing (FASPIP) tool for use in elderly hospitalized patients was developed. Validation of the FASPIP in the clinical setting is needed.   Type: Revie

Nucleosomes in serum as a marker for cell death

The concentration of nucleosomes is elevated in blood of patients with diseases which are associated with enhanced cell death. In order to detect these circulating nucleosomes, we used the Cell Death Detection-ELISA(Plus) (CDDE) from Roche Diagnostics (Mannheim, Germany) (details at http:\textbackslash{}\textbackslash{}biochem.roche.com). For its application in liquid materials we performed various modifications: we introduced a standard curve with nucleosome-rich material, which enabled direct quantification and improved comparability of the values within (CVinterassay:3.0-4.1%) and between several runs (CVinterassay:8.6-13.5%), and tested the analytical specificity of the ELISA. Because of the fast elimination of nucleosomes from circulation and their limited stability, we compared plasma and serum matrix and investigated in detail the pre-analytical handling of serum samples which can considerably influence the test results. Careless venipuncture producing hemolysis, delayed centrifugation and bacterial contamination of the blood samples led to false-positive results; delayed stabilization with EDTA and insufficient storage conditions resulted in false-negative values. At temperatures of -20 degreesC, serum samples which were treated with 10 mM EDTA were stable for at least 6 months. In order to avoid possible interfering factors, we recommend a schedule for the pre-analytical handling of the samples. As the first stage, the possible clinical application was investigated in the sera of 310 persons. Patients with solid tumors (n = 220; mean = 361 Arbitrary Units (AU)) had considerably higher values than healthy persons (n = 50; mean = 30 AU; P = 0.0001) and patients with inflammatory diseases (n = 40; mean = 296 AU; p = 0.096). Within the group of patients with tumors, those in advanced stages (UICC 4) showed significantly higher values than those in early stages (UICC 1-3) (P = 0.0004)

Meeting Faculty Development Needs via Inclusive Processes in a Newly Established College of Pharmacy

Objectives: Professional faculty development is essential in establishing the skills necessary to become both leaders in education and research. Changes were necessary for our College in this area. This study describes the development of a comprehensive faculty development program that is in compliance with the new ACPE Standards 2016. Methods: In fall 2013, the College reappointed a new chair of the faculty development committee (FDC). A needs assessment survey was created and circulated amongst the faculty members requesting prioritization of several key focus areas and measureable ACPE standard outcomes that were lacking and required immediate attention. Results: The FDC has updated and solidified many fundamental College policies and procedures surrounding the academic plan, performance appraisals and contract renewal processes. A peer evaluation procedure and tool were created to provide non –punitive feedback to faculty in an attempt to identify strengths and weaknesses. For new hires, a faculty orientation program was created for chairs and a mentoring plan was developed to identify and address obstacles in challenges early in their role. Over fifteen workshops were also offered to assist in personal and professional development within the last 18 months. Administration is currently devising a plan to alleviate teaching loads to allow faculty additional time to pursue scholarship. Faculty perception of the FDC effectiveness improved from 37.7% to 97% based on AACP/ACPE survey results. Implications: It is essential to the growth of any institution to make a concerted effort to incorporate inclusive processes amongst faculty for successful decision making strategies

Nucleosomes in serum of patients with early cerebral stroke

Background: Nucleosomes are cell death products that are elevated in serum of patients with diseases that are associated with massive cell destruction. We investigated the kinetics of circulating nucleosomes after cerebral stroke and their correlation with the clinical status. Methods: In total, we analyzed nucleosomes by ELISA in sera of 63 patients with early stroke daily during the first week after onset. For correlation with the clinical pathology, patients were grouped into those with medium to slight functional impairment (Barthel Index BI >= 50) and those with severe functional impairment (BI = 50 showed a continuous increase in nucleosomes until day 5 (median: 523 arbitrary units, AU) followed by a slow decline. In contrast, patients with BI = 50 (497 AU; p = 0.031). Concerning the infarction volume, nucleosomes showed significant correlations for the concentrations on day 3 (r = 0.43; p = 0.001) and for the area under the curve (r = 0.34; p = 0.016). Conclusion: Even if nucleosomes are nonspecific cell death markers, their release into serum after cerebral stroke correlates with the gross functional status as well as with the infarction volume and can be considered as biochemical correlative to the severity of stroke.

LSST: from Science Drivers to Reference Design and Anticipated Data Products

(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, and LSST will have unique survey capability in the faint time domain. The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the Solar System, exploring the transient optical sky, and mapping the Milky Way. LSST will be a wide-field ground-based system sited at Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m effective) primary mirror, a 9.6 deg$^2$ field of view, and a 3.2 Gigapixel camera. The standard observing sequence will consist of pairs of 15-second exposures in a given field, with two such visits in each pointing in a given night. With these repeats, the LSST system is capable of imaging about 10,000 square degrees of sky in a single filter in three nights. The typical 5$\sigma$ point-source depth in a single visit in $r$ will be $\sim 24.5$ (AB). The project is in the construction phase and will begin regular survey operations by 2022. The survey area will be contained within 30,000 deg$^2$ with $\delta<+34.5^\circ$, and will be imaged multiple times in six bands, $ugrizy$, covering the wavelength range 320--1050 nm. About 90\% of the observing time will be devoted to a deep-wide-fast survey mode which will uniformly observe a 18,000 deg$^2$ region about 800 times (summed over all six bands) during the anticipated 10 years of operations, and yield a coadded map to $r\sim27.5$. The remaining 10\% of the observing time will be allocated to projects such as a Very Deep and Fast time domain survey. The goal is to make LSST data products, including a relational database of about 32 trillion observations of 40 billion objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures available from https://www.lsst.org/overvie

The Tyrphostin Agent AG490 Prevents and Reverses Type 1 Diabetes in NOD Mice

<div><h3>Background</h3><p>Recent studies in the NOD (non-obese diabetic) mouse model of type 1 diabetes (T1D) support the notion that tyrosine kinase inhibitors have the potential for modulating disease development. However, the therapeutic effects of AG490 on the development of T1D are unknown.</p> <h3>Materials and Methods</h3><p>Female NOD mice were treated with AG490 (i.p, 1 mg/mouse) or DMSO starting at either 4 or 8 week of age, for five consecutive week, then once per week for 5 additional week. Analyses for the development and/or reversal of diabetes, insulitis, adoptive transfer, and other mechanistic studies were performed.</p> <h3>Results</h3><p>AG490 significantly inhibited the development of T1D (p = 0.02, p = 0.005; at two different time points). Monotherapy of newly diagnosed diabetic NOD mice with AG490 markedly resulted in disease remission in treated animals (n = 23) in comparision to the absolute inability (0%; 0/10, p = 0.003, Log-rank test) of DMSO and sustained eugluycemia was maintained for several months following drug withdrawal. Interestingly, adoptive transfer of splenocytes from AG490 treated NOD mice failed to transfer diabetes to recipient NOD.<em>Scid</em> mice. CD4 T-cells as well as bone marrow derived dendritic cells (BMDCs) from AG490 treated mice, showed higher expression of Foxp3 (p<0.004) and lower expression of co-stimulatory molecules, respectively. Screening of the mouse immune response gene arrary indicates that expression of costimulaotry molecule Ctla4 was upregulated in CD4+ T-cell in NOD mice treated with AG490, suggesting that AG490 is not a negative regulator of the immune system.</p> <h3>Conclusion</h3><p>The use of such agents, given their extensive safety profiles, provides a strong foundation for their translation to humans with or at increased risk for the disease.</p> </div

Nitrated nucleosome levels and neuropsychiatric events in systemic lupus erythematosus; a multi-center retrospective case-control study

To access publisher's full text version of this article, please click on the hyperlink in Additional Links field or click on the hyperlink at the top of the page marked FilesBACKGROUND: In patients with systemic lupus erythematosus (SLE) there is no serological test that will reliably distinguish neuropsychiatric (NP) events due to active SLE from those due to other causes. Previously we showed that serum levels of nitrated nucleosomes (NN) were elevated in a small number of patients with NPSLE. Here we measured serum NN in samples from a larger population of patients with SLE and NP events to see whether elevated serum NN could be a marker for NPSLE. METHODS: We obtained serum samples from patients in the Systemic Lupus International Collaborative Clinics (SLICC) inception cohort. This included 216 patients with NP events and two matched controls with SLE but no NP events for each of these patients. For the NP patients we tested samples taken before, during and after the NP event. RESULTS: Twenty-six patients had events attributed to SLE according to the most stringent SLICC attribution rule. In these patients there was no association between onset of event and elevated serum NN. In 190 patients in whom events were not attributed to SLE by the SLICC rules, median serum NN was elevated at the onset of event (P = 0.006). The predominant clinical features in this group of 190 patients were headache, mood disorders and anxiety. CONCLUSIONS: Serum NN levels rise at the time of an NP event in a proportion of patients with SLE. Further studies are needed to determine the value of serum NN as a biomarker for NPSLE.LUPUS UK Rosetrees Trust Arthritis Research UK Programme Grant National Institute for Health Research (NIHR) University College London Hospitals Biomedical Research Centre Canadian Institutes of Health Research Hanyang University Sandwell and West Birmingham Hospitals National Health Service (NHS) Trust IHR/Wellcome Trust Clinical Research Facility in Birmingham National Institutes of Health (NIH) Singer Family Fund for Lupus Research Arthritis Research UK National Institute for Health Research Manchester Biomedical Research Unit NIHR/Wellcome Trust Manchester Clinical Research Facility Danish Rheumatism Association Novo Nordisk Foundation NIH Department of Education, Universities and Research of the Basque Government Arthritis Research U
