Patients’ use of information about medicine side effects in relation to experiences of suspected adverse drug reactions

Background Adverse drug reactions (ADRs) are common, and information about medicines is increasingly widely available to the public. However, relatively little work has explored how people use medicines information to help them assess symptoms that may be suspected ADRs. Objective Our objective was to determine how patients use patient information leaflets (PILs) or other medicines information sources and whether information use differs depending on experiences of suspected ADRs. Method This was a cross-sectional survey conducted in six National Health Service (NHS) hospitals in North West England involving medical in-patients taking at least two regular medicines prior to admission. The survey was administered via a questionnaire and covered use of the PIL and other medicines information sources, perceived knowledge about medicines risks/ADRs, experiences of suspected ADRs, plus demographic information. Results Of the 1,218 respondents to the survey, 18.8 % never read the PIL, whilst 6.5 % only do so if something unexpected happens. Educational level was related to perceived knowledge about medicines risks, but not to reading the PIL or seeking further information about medicines risks. Over half the respondents (56.0 %) never sought more information about possible side effects of medicines. A total of 57.2 % claimed they had experienced a suspected ADR. Of these 85.9 % were either very sure or fairly sure this was a reaction to a medicine. Over half of those experiencing a suspected ADR (53.8 %) had read the PIL, of whom 36.2 % did so before the suspected ADR occurred, the remainder afterwards. Reading the PIL helped 84.8 % of these respondents to decide they had experienced an ADR. Educational level, general knowledge of medicines risks and number of regular medicines used all increased the likelihood of experiencing an ADR. Conclusion More patients should be encouraged to read the PIL supplied with medicines. The results support the view that most patients feel knowledgeable about medicines risks and suspected ADRs and value information about side effects, but that reading about side effects in PILs or other medicines information sources does not lead to experiences of suspected ADRs

Vibrio parahemolyticus septicaemia in a liver transplant patient: a case report

<p>Abstract</p> <p>Introduction</p> <p><it>Vibrio parahemolyticus </it>is the leading cause of vibrio-associated gastroenteritis in the United States of America, usually related to poor food handling; only rarely has it been reported to cause serious infections including sepsis and soft tissue infections. In contrast, <it>Vibrio vulnificus </it>is a well-known cause of septicaemia, especially in patients with cirrhosis. We present a patient with <it>V. parahemolyticus </it>sepsis who had an orthotic liver transplant in 2007 and was on immunosuppression for chronic rejection. Clinical suspicion driven by patient presentation, travel to Gulf of Mexico and soft tissue infection resulted in early diagnosis and institution of appropriate antibiotic therapy.</p> <p>Case presentation</p> <p>A 48 year old Latin American man with a history of chronic kidney disease, orthotic liver transplant in 2007 secondary to alcoholic end stage liver disease on immunosuppressants, and chronic rejection presented to the emergency department with fever, vomiting, abdominal pain, left lower extremity swelling and fluid filled blisters after a fishing trip in the Gulf of Mexico. Samples from the blister and blood grew <it>V. parahemolyticus</it>. The patient was successfully treated with ceftriaxone and ciprofloxacin.</p> <p>Conclusion</p> <p>Febrile patients with underlying liver disease and/or immunosuppression should be interviewed regarding recent travel to a coastal area and seafood ingestion. If this history is obtained, appropriate empiric antibiotics must be chosen. Patients with liver disease and/or immunosuppresion should be counselled to avoid eating raw or undercooked molluscan shellfish. People can prevent <it>Vibrio </it>sepsis and wound infections by proper cooking of seafood and avoiding exposure of open wounds to seawater or raw shellfish products.</p

Start-to-end simulations of plasma-wakefield acceleration using the MAX IV Linear Accelerator

Plasma-wakefield acceleration (PWFA) relies on the interaction between intense particle bunches and plasma for reaching higher accelerating gradients than what is possible with conventional radio-frequency technology. Using ultra-relativistic beam drivers allows for long acceleration lengths and have potential applications such as energy booster stages for synchrotron light sources or linear colliders and generating ultra-high-brightness beams from the background plasma. In this article, we present start-to-end simulations of the MAX IV Linear Accelerator as part of our investigations into the feasibility of using the linac for a PWFA experiment. We find that PWFA appears to be a viable application for the linac. A part of this conclusion is based on our finding that the general properties of the bunch compressor type employed in the MAX IV linac are well-suited for efficient generation of PWFA-optimized bunch current profiles, both for single- and double-bunch beams

Genetic differentiation among host-associated Alebra leafhoppers (Hemiptera: Cicadellidae)

The limited importance ascribed to sympatric speciation pro cesses via host race formation is partially due to the few cases of host races that have been reported among host populations. This work sheds light on the taxonomy of Alebra leafhoppers and examines the possible existence of host races among host-associated populations. The species of this genus show varying degrees of host association with deciduous trees and shrubs and, frequently, host popu lations of uncertain taxonomic status coexist and occasion ally become pests. Allozyme electrophoresis of 21 Greek populations including sympatric, local and geographically distant samples collected on 13 different plant species, show that they represent at least five species: A. albostriella Falle´n, A. viridis (Rey) (sensu Gillham), A. wahlbergi Bo Keywords: host races; leafhoppers; sympatric speciation; sibling species; allozymes; Alebra Introduction Sympatric speciation is a controversial subject in evol utionary biology (see Mayr, 1963; Futuyma and Mayer, 1980; Paterson, 1981; Via, 2001). One of the reasons for this controversy is that sympatric speciation seems to be an extremely rare phenomenon occurring only in very few groups of taxa, represented chiefly by phytophagous insects (Tauber and Tauber, 1977; Menken, 1981; Wood, 1993; Emelianov et al, 1995; Via, 1999; Finchak et al, 2000; Craig et al, 2001). The limited number of reported cases among organisms with sexual reproduction can be at least partially attributed to the fact that taxa undergoing sympatric speciation events must fulfill very restrictive biological and ecological requirements. Most sympatric speciation models demand that there is intraspecific genetic variation in traits that differentially affect the fitness of individuals that colonise new habitats or hosts (Dieckman and Doebeli, 1999; Hawthorne and Via, 2001 but see Higashi et al, 1999 and Takimoto et al, 2000). They assume that selection acting on these traits can prevent genetic exchange between populations (Bush, 1975; Tauber and Tauber, 1977; Diehl and Bush, 1989). In phytophagous insects, this means that host pref erences must be genetically determined and mating should occur on the host (Bush, 1975; Diehl and Bush, Correspondence: D Aguin-Pombo, Department of Biology, University of Madeira, Campus Universitario da Penteada, 9000 Funchal, Madeira, Portugal. E-mail: aguin uma.pt Received 12 December 2000; accepted 13 December 2001 heman and two new species. Of these, one is associated to Quercus frainetto and other is specific to Crataegus spp. Significant genetic differences among sympatric and local host populations were found only in A. albostriella, between populations on Turkey oak, beech and common alder. It is suggested that the last two of these host populations may represent different host races. The results show that both the host plant and geographical distance affect the patterns of differentiation in the genus. The formation of some spec ies seems to have been the result of allopatric speciation events while, for others, their origin can be equally explained either by sympatric or allopatric speciation.info:eu-repo/semantics/publishedVersio

How do you say ‘hello’? Personality impressions from brief novel voices

On hearing a novel voice, listeners readily form personality impressions of that speaker. Accurate or not, these impressions are known to affect subsequent interactions; yet the underlying psychological and acoustical bases remain poorly understood. Furthermore, hitherto studies have focussed on extended speech as opposed to analysing the instantaneous impressions we obtain from first experience. In this paper, through a mass online rating experiment, 320 participants rated 64 sub-second vocal utterances of the word ‘hello’ on one of 10 personality traits. We show that: (1) personality judgements of brief utterances from unfamiliar speakers are consistent across listeners; (2) a two-dimensional ‘social voice space’ with axes mapping Valence (Trust, Likeability) and Dominance, each driven by differing combinations of vocal acoustics, adequately summarises ratings in both male and female voices; and (3) a positive combination of Valence and Dominance results in increased perceived male vocal Attractiveness, whereas perceived female vocal Attractiveness is largely controlled by increasing Valence. Results are discussed in relation to the rapid evaluation of personality and, in turn, the intent of others, as being driven by survival mechanisms via approach or avoidance behaviours. These findings provide empirical bases for predicting personality impressions from acoustical analyses of short utterances and for generating desired personality impressions in artificial voices

Potentiality in Aristotle's psychology and ethics

The distinction between potentiality and actuality in Aristotle has its origin in Platonic ethics. In his psychological and ethical works Aristotle’s notion of potentiality is embedded in a causal framework that is characteristic of life in general. A key theme is the distinction of various meanings of ‘to know’. In his early work the possession of knowledge is distinguished from its use. In De anima Aristotle adds the potentiality for acquiring knowledge as characteristic of the genus human being. He argues that the stages of actualization of knowledge are instances of a more comprehensive biological and ethical development. Life is the fulfillment of soul as formal, efficient and final cause, with the potentiality of body as material cause. The unity of body and soul is derived from the causal nexus of potentiality and actuality, like a power and the instrument in which it resides. In such cases potentiality is complex and depends on numerous conditions. Failure of full realization may occur when any of the necessary conditions of the development and realization of the fulfillment of human life are lacking, whether in the environment (e.g. climate), the body (illness, drunkenness), or the soul (natural virtue, firm character, attention).Political Philosophy and Ethic

<p>Abstract</p> <p>Background</p> <p>This study aims to describe and analyze hospital admissions in Spain due to rotavirus infections among children aged 5 years or under during the period 2001–2005, along with the associated health cost.</p> <p>Methods</p> <p>To update estimates of rotavirus hospitalizations rates in Spain, we conducted a retrospective study of 5 years of national hospitalization data associated with acute gastroenteritis using the Minimum Basic Data Set.</p> <p>Results</p> <p>During the study period, a total of 17.1% of all admissions due to acute gastroenteritis of any etiology in children aged ≤ 5 years were attributable to rotavirus infection as determined by the rotavirus-specific International Classification of Diseases, ninth revision, Clinical Modification code. A mean incidence of 135 hospital admissions attributable to rotavirus per 100,000 children aged ≤ 5 years was found. Hospitalizations associated with rotavirus had a marked winter-time seasonality. The estimated cost of hospital admission attributable to rotavirus has risen from 3 million euros estimated for 2001 to almost 7 million euros estimated in 2005.</p> <p>Conclusion</p> <p>Rotavirus gastroenteritis remains an important cause of hospitalizations in Spanish children, mostly during the winter season.</p

Racial differences in smoking abstinence rates in a multicenter, randomized, open-label trial in the United States

Background: This study evaluates differences in smoking abstinence between white and minority smokers using pharmaceutical aids. Methods: This is an analysis of data from a multi-center, randomized, clinical trial conducted in the United States. Of the 1,684 subjects randomized to one of three medications (nicotine inhaler, bupropion, or a combination of both), 60% were women and 10% were minority races. Results: Factors associated with a decreased likelihood of smoking at 12 weeks were older age (OR = 0.971, p\u3c 0.0001), being married (OR = 0.678, p= 0.0029), using bupropion SR (OR = 0.480, p∈\u3c∈0.0001), and using combination therapy (OR = 0.328, p∈\u3c∈0.0001). Factors associated with an increased likelihood of smoking were higher tobacco dependence scores (OR = 1.244, p \u3c 0.0001), prior quit attempts (OR = 1.812, p=0.004), and being a minority (OR = 1.849, p=0.0083). Compared to white smokers, minority smokers were significantly older at time of study entry (46 vs. 42 years, p\u3c 0.0001), less likely to be married (35% vs. 59%, p\u3c 0.0001), older at smoking initiation (21 vs. 19 years of age, p\u3c 0.0001), and had a lower abstinence rate (16% vs. 26%, p=0.0065). Conclusion: Regardless of the treatment used, minority smokers in the US have lower smoking abstinence after treatment for tobacco dependence. Future research should focus on the improvement in treatment strategies for minority smokers
