MyHits: a new interactive resource for protein annotation and domain identification.

The MyHits web server (http://myhits.isb-sib.ch) is a new integrated service dedicated to the annotation of protein sequences and to the analysis of their domains and signatures. Guest users can use the system anonymously, with full access to (i) standard bioinformatics programs (e.g. PSI-BLAST, ClustalW, T-Coffee, Jalview); (ii) a large number of protein sequence databases, including standard (Swiss-Prot, TrEMBL) and locally developed databases (splice variants); (iii) databases of protein motifs (Prosite, Interpro); (iv) a precomputed list of matches ('hits') between the sequence and motif databases. All databases are updated on a weekly basis and the hit list is kept up to date incrementally. The MyHits server also includes a new collection of tools to generate graphical representations of pairwise and multiple sequence alignments including their annotated features. Free registration enables users to upload their own sequences and motifs to private databases. These are then made available through the same web interface and the same set of analytical tools. Registered users can manage their own sequences and annotations using only web tools and freeze their data in their private database for publication purposes.

Is (1→3)-β-D-glucan the missing link from bedside assessment to pre-emptive therapy of invasive candidiasis?

ABSTRACT: Invasive candidiasis is a frequent life-threatening complication in critically ill patients. Early diagnosis followed by prompt treatment aimed at improving outcome by minimizing unnecessary antifungal use remains a major challenge in the ICU setting. Timely patient selection thus plays a key role for clinically efficient and cost-effective management. Approaches combining clinical risk factors and Candida colonization data have improved our ability to identify such patients early. While the negative predictive value of scores and predicting rules is up to 95 to 99%, the positive predictive value is much lower, ranging between 10 and 60%. Accordingly, if a positive score or rule is used to guide the start of antifungal therapy, many patients may be treated unnecessarily. Candida biomarkers display higher positive predictive values; however, they lack sensitivity and are thus not able to identify all cases of invasive candidiasis. The (1→3)-β-D-glucan (BG) assay, a panfungal antigen test, is recommended as a complementary tool for the diagnosis of invasive mycoses in high-risk hemato-oncological patients. Its role in the more heterogeneous ICU population remains to be defined. More efficient clinical selection strategies combined with performant laboratory tools are needed in order to treat the right patients at the right time by keeping costs of screening and therapy as low as possible. The new approach proposed by Posteraro and colleagues in the previous issue of Critical Care meets these requirements. A single positive BG value in medical patients admitted to the ICU with sepsis and expected to stay for more than 5 days preceded the documentation of candidemia by 1 to 3 days with an unprecedented diagnostic accuracy. Applying this one-point fungal screening on a selected subset of ICU patients with an estimated 15 to 20% risk of developing candidemia is an appealing and potentially cost-effective approach. If confirmed by multicenter investigations, and extended to surgical patients at high risk of invasive candidiasis after abdominal surgery, this Bayesian-based risk stratification approach aimed at maximizing clinical efficiency by minimizing health care resource utilization may substantially simplify the management of critically ill patients at risk of invasive candidiasis.

New interactive resource feeds children's curiosity

The Public Health Agency and safefood today (Wednesday 22 June) officially launched Eat, Taste and Grow, a new interactive curriculum based education resource to help increase awareness among primary school children of the origins of their food, local produce and the role this plays in healthy eating. As research in 2006 showed, 18% of children aged 2-15 years in Northern Ireland were reported to be obese; and provisional data in 2008-2009 showed that 22.5% of children entering Year 1 were already overweight (17%) or obese (5%).* The launch of Eat, Taste and Grow is an innovative collaboration between the PHA and safefood that will provide children with lifelong lessons about the food they eat, healthy eating options and the benefits of an active lifestyle.The free teacher-led CD-ROM resource will be sent to every primary school across Northern Ireland by September 2011 and will help increase awareness among primary school children of the origins of their food and local produce, and the role this plays in healthy eating.Speaking at the event, Health Minister Edwin Poots said: "Being obese as a child can store up problems for the future, leading to a reduction in life expectancy and potentially causing other health problems such as increased risk of coronary heart disease, cancer and Type 2 Diabetes."Currently around one in four girls and one in six boys in Primary One (Year 1) are overweight or obese."Many of our children are not as physically active as they should be, nor do they have a healthy, balanced diet."This new resource will help teachers in our primary schools educate children on how to choose what foods are healthier for them which hopefully they will carry with them into adulthood."Dr Eddie Rooney, Chief Executive, PHA said: "The Public Health Agency recognises the need to give every child a healthy start in life. Schools play a vital role in contributing to the development of knowledge and skills necessary to make healthier food choices and laying the foundation for good eating habits which can then be carried through into adulthood. Eat, Taste and Grow is an excellent resource that will help equip teachers to carry out this role and in turn enable children to make healthier choices."Mr Martin Higgins, CEO safefood said: "We know and understand the challenges faced by parents to encourage children to eat healthy foods. As obesity among children continues to rise, this interactive resource will educate children in a fun and engaging way while providing them with the information to make informed, responsible choices throughout their lives."The Eat, Taste and Grow resource is an interactive CD-ROM for use on a whiteboard or computer and is divided into: Foundation, Key Stage 1 and Key Stage 2. Topics include 'Where does our food come from?', 'Who produces our food?', 'How food grows' and 'How food is produced and preserved'. Each topic has accompanying teacher's notes and includes ideas for classroom discussions, role play, games and quiz suggestions.

Efficiency of flexible derotator in walking cerebral palsy children

Introduction The flexible derotator is one of the therapeutic resources used to combat primary and secondary abnormalities in walking cerebral palsy children. It was developed to reduce abnormal femoral and tibial torsions and lessen the latter's negative functional impact. Objective To determine the effect of wearing a flexible derotator on anatomic and functional parameters in walking cerebral palsy children. Methods We performed a retrospective study of walking cerebral palsy children by gathering data on bone-related parameters (femoral and tibial torsion) and functional parameters (distance and speed gait, and the energy expenditure index (EEI)). Fifteen walking cerebral palsy children were treated with the flexible derotator for one year and 15 untreated walking cerebral palsy children were included as controls. The two groups were compared in terms of the various parameters' change over time between the initial examination (the last examination prior to the start of the study or prior to use of the flexible derotator) and the final examination (after one year of follow-up). Results Right femoral anteversion and right and left external tibial torsion improved. There was a significant increase in distance and speed gait and a decrease in the EEI in walking cerebral palsy children. Conclusion Our retrospective study revealed a significant improvement in functional parameters in children with cerebral palsy, as a result of wearing the flexible derotator for at least 6 hours a day for a year. Bone parameters only improved slightly. Use of the flexible derotator could improve these children's quality of life.

A Prevalence Study of Drug use by Young People in a Mixed Suburban Area

This report aims to determine the levels and patterns of drug use, including tobacco and alcohol, among young people in the Kilbarrack area. Questionnaires were sent to students from all primary and secondary schools in the target area, and were also sent to young people in the area who had already left school. The survey showed that 24% of respondents had smoked tobacco at some stage in their lives, with 25% listed as current smokers. Older students reported higher tobacco use, with over 40% of 16-18 year olds currently smoking. Alcohol was the drug most widely used by respondents, with 76% of all students having taken it at some stage in their lives. Prevalence of current alcohol use was higher in older children, with 84% of 16-18 year olds currently drinking as opposed to 61% of 13-15 year olds and 17% for 10 to 12 year olds. Cannabis was the most widely used illicit drug, with 37% of respondents using the drug at some stage. The next most widely used drug was inhalants, with 16% having used them at some stage, with 6% having used cocaine at some stage in their lives; the same proportion had used it within the last 12 months. There little or no significant evidence of heroin use. The report recommends prevention programmes that ensure that young people have other things in their lives other than alcohol/ drugs, such as a comprehensive range of properly resourced sporting and youth work in the community.This resource was contributed by The National Documentation Centre on Drug Use.

A Report from a Local Initiative Concerning Alcohol / Drug Use Among Teenagers 1998-1999

This study was carried out by participants in a North Tipperary Community Services drug/alcohol awareness course. Its objectives were to: assess the level of drug and alcohol awareness among second-level students under the age of 18 years; to find out the extent of under-age drinking;to find out the extent of the use of illegal substances as well as stimulants such as glue and solvents in this age group; and to use this information to develop educational programmes for parents and students. Date was obtained through a survey of 1500 secondary school students in the North Tippeary area. The survey found that, although ilict drug use was very low, abuse of alcohol was quite common.This resource was contributed by The National Documentation Centre on Drug Use.

A Survey of Poly-drug (Multiple-drug) Use Among Patients Receiving Methadone for the Treatment of their Opioid Addiction in the Northern Area Health Board

The objective of this study is to determine the extent of the problem of poly-drug (multiple-drug) use among patients receiving methadone. The study investigated levels and patterns of cocaine and cannabis use in opiate dependent patients receiving methadone treatment. This research also examines risks associated with injecting cocaine. A total number of 851 methadone patients receiving treatment for opiate related problems participated in the survey from a total number of 1082 patients receiving treatment in these clinics. This figure accounts for 80.1%. Participants reported the frequency and intensity of cocaine and cannabis use. Data collected showed that 42% of the methadone patients are using cannabis on a daily basis and that 77.47% had a history of cocaine use. The figure of cocaine use is an important indicator of the level and extent of cocaine use. It is valuable from a public health perspective to assess needs, and to plan and evaluate services. The survey concluded that cocaine abuse is emerging as a problem in the Irish drug sceneThis resource was contributed by The National Documentation Centre on Drug Use.

Accident & Emergency Nursing Assessment of Deliberate Self Harm. Exploring the Impact of Introducing a Suicide Education Programme and a Suicide Intent Scale into A&E/MAU Nursing Practice: A Pilot Study

A proposal to pilot nursing assessment of self harm in Accident and Emergency Departments (A&E) was developed by key stakeholders in nurse education and suicide prevention in the South East and submitted to the National Council for the Professional Development of Nursing and Midwifery in April 2002.The proposal included the introduction of a suicide intent scale. Following an initial training programme, a suicide intent scale was utilised by nursing staff in A&E and the Medical Assessment Unit (MAU),Wexford General Hospital and evaluated over a period of nine months. Four months into the study the National Suicide Research Foundation (NSRF) was invited to collaboratively prepare a successful submission to the Health Research Board (HRB) as part of ‘Building Partnerships for a Healthier Future Research Awards 2004’. The NSRF undertook independent scientific evaluation of the outcomes of the suicide awareness programme. The study is in line with priorities determined by Reach Out, the National Strategy for Action on Suicide Prevention 2005-2014 (HSE, 2005) and the HSE-South East Suicide Prevention Programme through raising nursing staff awareness of the public health issue of suicide/deliberate self harm and by improving the efficiency and quality of nursing services offered to persons who present to acute hospitals with deliberate self harm. The study findings indicate evidence to positively support nursing assessment of DSH using a suicide intent scale in terms of assessing behavioural characteristics of individual clients and their suicide risk. Enhanced confidence levels of nursing personnel in caring for suicidal clients was demonstrated by staff who participated in an education programme related to risk assessment and specifically the use of a suicide intent scale.This resource was contributed by The National Documentation Centre on Drug Use.

Safety and feasibility of NeuroFlo use in eight- to 24-hour ischemic stroke patients.

BACKGROUND: Acute treatment of ischemic stroke patients presenting more than eight-hours after symptom onset remains limited and largely unproven. Partial aortic occlusion using the NeuroFlo catheter can augment cerebral perfusion in animals. We investigated the safety and feasibility of employing this novel catheter to treat ischemic stroke patients eight-hours to 24 h following symptom onset. METHODS: A multicenter, single-arm trial enrolled ischemic stroke patients at nine international academic medical centers. Eligibility included age 18-85 years old, National Institutes of Health stroke scale (NIHSS) score between four and 20, within eight-hours to 24 h after symptom onset, and perfusion-diffusion mismatch confirmed by magnetic resonance imaging. The primary outcome was all adverse events occurring from baseline to 30 days posttreatment. Secondary outcomes included stroke severity on neurological indices through 90 days. This study is registered with ClinicalTrials.gov, number NCT00436592. RESULTS: A total of 26 patients were enrolled. Of these, 25 received treatment (one excluded due to aortic morphology); five (20%) died. Favorable neurological outcome at 90 days (modified Rankin score 0-2 vs. 3-6) was associated with lower baseline NIHSS (P < 0·001) and with longer duration from symptom discovery to treatment. There were no symptomatic intracranial hemorrhages or parenchymal hematomas. Asymptomatic intracranial hemorrhage was visible on computed tomography in 32% and only on microbleed in another 20%. CONCLUSIONS: Partial aortic occlusion using the NeuroFlo catheter, a novel collateral therapeutic strategy, appears safe and feasible in stroke patients eight-hours to 24 h after symptom onset.

A Study of Tobacco, Alcohol and Drug Use among Irish Female Prisoners

The female prisoner population are a very specific group with very different needs to that of the general population. The study sets out to profile these women and to examine their use of tobacco, alcohol and other substances. A census sample of female prisoners was frequency matched for age with male prisoners and also the female general population. Response rate was 74.6%. Results illustrated that female prisoners are, in the majority from a lower social group, from deprived backgrounds and from families where unemployment is high and education is low. Female prisoners smoke more, take more drugs (including heroin and injection drugs) and drink considerably more when compared to the above groups. They have more alcohol related difficulties as a result of another persons drinking, illustrating high rates of verbal, physical and sexual assault. The prison setting may be the first and possibly the only opportunity for health education and promotion for this particular group. Therefore, with such high reported levels of smoking, alcohol and other substance use, the prison provides a good setting for health promotion interventions.This resource was contributed by The National Documentation Centre on Drug Use.

Travellers and substance use in Ireland: Recommendations for drug and alcohol policy

The Traveller community was traditionally protected from drug use by distinct traditional anti-drug norms and potent family networks within their ‘separateness’ from the ‘settled’ community. Estimations of Traveller substance use remain clouded due to lack of ethnic monitoring in drug reporting systems, and poor service utilization by Travellers. This article draws on a Traveller and substance use regional needs analysis in Ireland, comprising 12 Traveller focus groups and 45 interviews with key stakeholders. Drug activity in terms of both drug dealing and drug use among Travellers is increasing in recent years [Van Hout, M.C. (2009a). Substance misuse in the traveller community: A regional needs assessment. Western Regional Drug Task Force. Series 2. ISBN 978-0-9561479-2-9].   Traditional resiliency factors are dissipating in strength due to increased Traveller housing within marginalized areas experiencing drug activity and increased levels of young Travellers encountering youth drug use within school settings, by way of their attempts ‘to fit in’ and integrate with their ‘settled peers’ [Van Hout, M.C. (2009b). Irish travellers and drug use – An exploratory study. Ethnicity and Inequalities in Health and Social Care, 2(1), 42–49]. Fragmentation of Traveller culture is occurring as Travellers strive to retain their identity within the assimilation process into modern sedentarist Irish society. Treatment and outreach policies need to protect Traveller identity by reducing discriminatory experiences, promoting cultural acceptance with service staff and addressing literacy, implementing peer led approaches and offering flexible therapy modalities.This resource was contributed by The National Documentation Centre on Drug Use.

A study of cocaine use in Northern Ireland 2009.

This study explored the patterns of cocaine use and the lifestyles of users in Northern Ireland with the aim of providing the Department of Health, Social Services and Public Safety (DHSSPS) and treatment service providers with a better understanding of cocaine use in Northern Ireland. This primarily qualitative study was conducted in two phases. In Phase I a â?~Community Assessment Processâ?T was conducted to gain an understanding of the experiences of drug treatment professionals to cocaine use in Northern Ireland. In phase II 40 in-depth interviews were conducted with cocaine users. The study identified two types of cocaine user, these are recreational or socially integrated users and those referred for drug treatment who as a group was socially marginalized users. For the purposes of this study these users will be referred to as either recreational or treatment users. The demographic profiles of each type of user differed in a number of important respects. The recreational users were typically young, educated and anchored to a largely conventional lifestyle and whose pattern of non-work activities involved partying and drug use. Treatment users, on the other hand, generally had low level educational qualifications and were typically unemployed and living on state benefits. A number of the treatment users were either living in a hostel at the time of interview or had experienced homelessness at some time in their life. None of the recreational users reported any experience of homelessness. These distinctions, as well as differences between the groups in terms of their drug use patterns, preferences and practices, strongly suggest that in unravelling the nature of cocaine use and cocaine problems there is a need to look beyond the drug itself.This resource was contributed by The National Documentation Centre on Drug Use.

International ADHD in substance use disorders prevalence study.

Dr Van Hout has been invited by the ICASA network and IASP research team [Drs Geurt van de Glind; Trimbos Institute, The Netherlands; Dr Pieter-Jan Carpentier, ICASA; Josep Antoni Ramos-Quiroga, University of Barcelona, Spain, Professor Dr Frances Levin, University of Columbia, New York, USA and Professor Dr. Wim van den Brink, University of Amsterdam, The Netherlands] to undertake the research protocol for Ireland as part of this European study of the prevalence of ADHD in adult patients referred for treatment of addiction problems. The research team at Waterford Institute of Technology, School of Health Sciences will undertake this national study as part of the International Collaboration on ADHD and Substance Abuse [ICASA] â?~International ADHD in Substance Use Disorders Prevalence Studyâ?T [IASP study]. The International Collaboration on ADHD and Substance Abuse [ICASA] will provide Dr Van Hout and her team with full support from ICASA of the measurement instruments available and a central database at the University of Amsterdam, and will undergo training for procedures for data capture from Dr van de Glind, Trimbos Institute, The Netherlands. Eight European countries (Norway, Sweden, the Netherlands, Belgium, France, Spain, Switzerland and Hungary) USA and Australia have already participated in the first phase of the IASP study, which will close in September 2011. Over 2500 Substance Use Disorder [SUD] patients were sampled with approximately 38% scoring positive on the ADHD screener (ASRS). Of these 2500 patients over 1000 patients were evaluated on ADHD, Depression, Bipolar Disorder, Anti-Social Personality and Borderline Personality Disorder. A preliminary estimate of the prevalence of ADHD in SUD treatment seeking patients was recorded at 20 %. The second phase of study [IASP 2011] will commence in September 2011 for countries including Ireland, South Africa, Egypt and Brazil. Dr Van Hout has also been invited to partake in a systematic review paper on the risk factors for development of SUD in children/adolescents with ADHD in collaboration with the ICASA foundation.This resource was contributed by The National Documentation Centre on Drug Use.
