MAKING FAMILIES AND CHILDREN A HIGH PRIORITY IN THE COURTS

FAMILY COURT REVIEW, Issue 4 2002
California's Center for Families, Children & the Courts
This article describes the California Administrative Office of the Court's (AOC's) Center for Families, Children & the Courts (CFCC). CFCC is an interdisciplinary unit that brings together all of the AOC's work on statewide policies and practices related to families and children in the court system. CFCC thus models the unified family court model within the state AOC. CFCC's projects and activities are described to show the effectiveness of its multidisciplinary and collaborative approach in addressing complex policy and practice issues. It is hoped that readers may discover aspects of CFCC's work that could be adapted to their own jurisdiction or practice. [source]


Policy interpretation network on children's health and environment

ACTA PAEDIATRICA, Issue 2006
PETER VAN DEN HAZEL
Abstract Aim: The main objective of PINCHE is to provide policy recommendations aiming at protecting children's health and environment based on completed scientific research. The project focused on four themes: indoor and outdoor air pollutants, carcinogens, neurotoxicants, and noise. The data were evaluated in workpackages on exposure assessment, epidemiology, toxicology, and risk and health impact assessment. The data were analysed according to a framework of questions. The workpackage on socioeconomic factors studied the influence of socioeconomic status on exposures and on health effects. In the workpackage on science-policy interface, recommendations on how to improve children's environmental health were formulated. Results: The policy recommendations resulting from the analysis were grouped according to relevant policy levels: European Commission or the European Parliament, member states and other stakeholders at regional or local level. These recommendations are general guidelines for taking action. Regional differences and variation must be reflected when policy is actually implemented. In addition, recommendations related to education and personal behaviour are presented in the reports. Conclusions: The policy recommendations are important input for policy advisers, policy makers and public health authorities at all policy levels. The recommendations are also of direct relevance to interest groups, such as environmental NGOs including child health and advocacy groups. The policy recommendations for each policy level were prioritized. High priorities were given to reduce exposure to environmental tobacco smoke, transport related air pollution, indoor air and mercury. [source]


Strategies for Implementing School-Located Influenza Vaccination of Children: A Systematic Literature Review

JOURNAL OF SCHOOL HEALTH, Issue 4 2010
John Cawley PhD
BACKGROUND: The Advisory Committee on Immunization Practices (ACIP) recommends influenza vaccinations for all children 6 months to 18 years of age, which includes school-aged children. Influenza immunization programs may benefit schools by reducing absenteeism. METHODS: A systematic literature review of PubMed, PsychLit, and Dissertation Abstracts available as of January 7, 2008, was conducted for school-located vaccinations, using search words "School Health Services" and "Immunization Programs"; limited to "Child" (6-12 years) and "Adolescent" (13-18 years) for PubMed and "mass or universal" and (immuniz* or immunis* or vaccin*) and (school or Child or Adolescen*) for PsychLit and Dissertation Abstracts. Fifty-nine studies met the criteria for review. RESULTS: Strategies such as incentives, education, the design of the consent form, and follow-up can increase parental consent and number of returned forms. Minimizing out-of-pocket cost, offering both the intramuscular (shot) and intranasal (nasal spray) vaccination, and using reminders can increase vaccination coverage among those whose parents consented. Finally, organization, communication, and planning can minimize the logistical challenges. CONCLUSIONS: Schools-based vaccination programs are a promising option for achieving the expanded ACIP recommendation; school-located vaccination programs are feasible and effective. Adhering to lessons from the peer-reviewed scientific literature may help public health officials and schools implement the expanded recommendation to provide the greatest benefit for the lowest cost. Given the potential benefits of the expanded recommendation, both directly to the vaccinated children and indirectly to the community, prospective, well-controlled trials to establish the cost-effectiveness of specific vaccination strategies should be high priorities for future research.

Help-seeking behaviour in patients with anxiety disorder and depression

ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2005
A. Roness
Objective:, The objective of this study was to investigate help-seeking behaviour among persons with anxiety disorder and depression based on self-rating in a Norwegian population (the HUNT study). Method:, Of the 92 100 inhabitants aged 20,89 years invited, 65 648 (71.3%) took part. Among them 60 869 (66.1%) persons delivered valid ratings on hospital anxiety and depression scale, and had answered the requested help for mental problems question. Results:, Among HUNT attenders 13% of those with depression and 25% with anxiety disorders had been help seekers. Help seeking was only non-significantly associated with demographic or other variables. Conclusion:, Most persons with anxiety disorder and/or depression in the population had not sought help for their mental disorders, but the disparity between use and need of health service must not be overassessed. Improvement of the help-seeking rate for common mental disorder should have high priority in mental health politics. [source]


Using multi-scale species distribution data to infer drivers of biological invasion in riparian wetlands

DIVERSITY AND DISTRIBUTIONS, Issue 1 2010
Jane A. Catford
Abstract Aim, Biological invasion is a major conservation problem that is of interest to ecological science. Understanding mechanisms of invasion is a high priority, heightened by the management imperative of acting quickly after species introduction. While information about invading species' ecology is often unavailable, species distribution data can be collected near the onset of invasion. By examining distribution patterns of exotic and native plant species at multiple spatial scales, we aim to identify the scale (of those studied) that accounts for most variability in exotic species abundance, and infer likely drivers of invasion. Location, River Murray wetlands, south-eastern Australia. Methods, A nested, crossed survey design was used to determine the extent of variation in wetland plant abundance, grazing intensity and water depth at four spatial scales (reaches, wetland clumps, wetlands, wetland sections), and among three Depth-strata. We examined responses of exotic and native species groups (grouped into terrestrial and amphibious taxa), native weeds and 10 individual species using hierarchical ANOVA. Results, As a group dominated by terrestrial taxa, exotic species cover varied at reach-, wetland- and section-scales. This likely reflects differences in abiotic characteristics and propagule pressure at these scales. Groups based on native species did not vary at any scale examined. Cover of 10 species mostly varied among and within wetlands (patterns unrelated to species' origin or functional group), but species' responses differed, despite individual plants being similar in size. While flora mostly varied among wetlands, exotic cover varied most among reaches (26%), which was attributed to hydrological modification and human activities. Main conclusions, Multi-scale surveys can rapidly identify factors likely to affect species' distributions and can indicate where future research should be directed. By highlighting disproportionate variation in exotic cover among reaches, this study suggests that flow regulation and human-mediated dispersal facilitate exotic plant invasion in River Murray wetlands.

Litigation and alcohol policy: lessons from the US Tobacco Wars

ADDICTION, Issue 2009
James F. Mosher
ABSTRACT Aims This paper explores the role of litigation in preventing alcohol-related harms, identifying lessons from the use of litigation in tobacco control policy in the United States. It analyzes the key components of litigation in an international context, provides a case study of its potential use in addressing the marketing of alcopops to youth and offers recommendations for pursuing litigation strategies in future alcohol policy efforts. Methods The paper's analyses are based on both original and secondary legal research. State and federal case law and secondary sources are reviewed in assessing lessons learned from tobacco litigation in the United States and the potential role of litigation in alcohol policy, both in the United States and internationally. Assessment of alcohol litigation cases and state and federal laws and regulations provides the foundation for the alcopops case study. Findings The tobacco litigation experience demonstrates that litigation is a powerful tool in addressing aggressive marketing by purveyors of addictive products such as alcohol. Conclusions To be effective at both national and international levels, litigation should encompass a broad array of legal tactics designed to identify and restrict unfair, deceptive and misleading alcohol marketing tactics and should be utilized in conjunction with complementary prevention strategies. Research conducted on the impact of alcohol marketing on youth alcohol consumption and problems is needed to support potential litigation claims. Developing litigation expertise within the alcohol policy field and building collaboration with litigation specialists in tobacco control should also be considered a high priority. [source]


A strategy to reduce the numbers of fish used in acute ecotoxicity testing of pharmaceuticals

ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 12 2003
Thomas H. Hutchinson
Abstract The pharmaceutical industry gives high priority to animal welfare in the process of drug discovery and safety assessment. In the context of environmental assessments of active pharmaceutical ingredients (APIs), existing U.S. Food and Drug Administration and draft European regulations may require testing of APIs for acute ecotoxicity to algae, daphnids, and fish (base-set ecotoxicity data used to derive the predicted no-effect concentration [PNECwater] from the most sensitive of three species). Subject to regulatory approval, it is proposed that testing can be moved from fish median lethal concentration (LC50) testing (typically using ,42 fish/API) to acute threshold tests using fewer fish (typically 10 fish/API). To support this strategy, we have collated base-set ecotoxicity data from regulatory studies of 91 APIs (names coded for commercial reasons). For 73 of the 91 APIs, the algal median effect concentration (EC50) and daphnid EC50 values were lower than or equal to the fish LC50 data. Thus, for approximately 80% of these APIs, algal and daphnid acute EC50 data could have been used in the absence offish LC50 data to derive PNECwater values. For the other 18 APIs, use of an acute threshold test with a step-down factor of 3.2 is predicted to give comparable PNECwater outcomes. Based on this preliminary scenario of 91 APIs, this approach is predicted to reduce the total number offish used from 3,822 to 1,025 (,73%). The present study, although preliminary, suggests that the current regulatory requirement for fish LC50 data regarding APIs should be succeeded by fish acute threshold (step-down) test data, thereby achieving significant animal welfare benefits with no loss of data for PNECwater estimates.

Social Functioning, Psychological Functioning, and Quality of Life in Epilepsy

EPILEPSIA, Issue 9 2001
Theo P. B. M. Suurmeijer
Summary: ,Purpose: Part of our research intended to explain "Quality of Life" (QoL) differences between people with epilepsy. To this end, a series of already existing generic and disease-specific health status measures were used. In this study, they were considered as determinants of people's QoL, whereas QoL itself was conceived as a general "value judgment" about one's life. Methods: From the records of four outpatient clinics, 210 persons with epilepsy were randomly selected. During their visit to the outpatient clinic, they completed a questionnaire assessing, among other things, health perceptions and social and psychological functioning. Additional information about their medical and psychosocial status was gathered from the patient files. Data were analysed by using a hierarchical regression analysis. Results: In decreasing order of importance, "psychological distress,""loneliness,""adjustment and coping," and "stigma perception" appeared to contribute most significantly to the outcome QoL as judged by the patients themselves, regardless of their physical status. In the final model, none of the clinical variables (onset, seizure frequency, side effects of antiepileptic drugs) contributed significantly anymore to the patients' "quality-of-life judgement." Apparently the effect of other variables such as seizure frequency and health perceptions, medication and side effects, life fulfilment, self-esteem, and mastery is mediated by these variables. Conclusions: Because all of the variance in QoL of the patients was explained by the psychosocial variables included in this study, health professionals should be aware of the significance of the psychosocial functioning of the patients and the role it plays in the achievement of a good QoL. Both informal and professional support may be an adjunct to conventional treatment. In future research, this issue should be given high priority. [source]


Immunization with heat-killed Francisella tularensis LVS elicits protective antibody-mediated immunity

EUROPEAN JOURNAL OF IMMUNOLOGY, Issue 11 2007
Christy
Abstract Francisella tularensis (FT) has been classified by the CDC as a category,A pathogen because of its high virulence and the high mortality rate associated with infection via the aerosol route. Because there is no licensed vaccine available for FT, development of prophylactic and therapeutic regimens for the prevention/treatment of infection is a high priority. In this report, heat-killed FT live vaccine strain (HKLVS) was employed as a vaccine immunogen, either alone or in combination with an adjuvant, and was found to elicit protective immunity against high-dose FT live vaccine strain (FTLVS) challenge. FT-specific antibodies produced in response to immunization with HKLVS alone were subsequently found to completely protect naive mice against high-dose FT challenge in both infection-interference and passive immunization experiments. Additional passive immunization trials employing serum collected from mice immunized with a heat-killed preparation of an O-antigen-deficient transposon mutant of FTLVS (HKLVS-OAgneg) yielded similar results. These findings demonstrated that FT-specific antibodies alone can confer immunity against high-dose FTLVS challenge, and they reveal that antibody-mediated protection is not dependent upon production of LPS-specific antibodies.

EFNS task force on management of amyotrophic lateral sclerosis: guidelines for diagnosing and clinical care of patients and relatives

EUROPEAN JOURNAL OF NEUROLOGY, Issue 12 2005
An evidence-based review with good practice points
Despite being one of the most devastating diseases known, there is little evidence for diagnosing and managing patients with amyotrophic lateral sclerosis (ALS). Although specific therapy is lacking, correct early diagnosis and introduction of symptomatic and specific therapy can have a profound influence on the care and quality of life of the patient and may increase survival time. This document addresses the optimal clinical approach to ALS. The final literature search was performed in the spring of 2005. Consensus recommendations are given graded according to the EFNS guidance regulations. Where there was lack of evidence but consensus was clear we have stated our opinion as good practice points. People affected with possible ALS should be examined as soon as possible by an experienced neurologist. Early diagnosis should be pursued and a number of investigations should be performed with high priority. The patient should be informed of the diagnosis by a consultant with a good knowledge of the patient and the disease. Following diagnosis, the patient and relatives should receive regular support from a multidisciplinary care team. Medication with riluzole should be initiated as early as possible. PEG is associated with improved nutrition and should be inserted early. The operation is hazardous in patients with vital capacity <50%. Non-invasive positive pressure ventilation improves survival and quality of life but is underused. Maintaining the patients ability to communicate is essential. During the entire course of the disease, every effort should be made to maintain patient autonomy. Advance directives for palliative end of life care are important and should be fully discussed early with the patient and relatives respecting the patients social and cultural background. [source]


The burden of hyperlipidaemia and diabetes in cardiovascular diseases

FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 2007
Marijan Merkler
Abstract Hyperlipidaemia and diabetes are among the major risk factors for cardiovascular diseases (CVD). The incidence of CVD, as evidenced by the respective mean incident rate for each of the risk factor, is quite high throughout the European countries. Of late, these risk factors for CVD, especially for hyperlipidaemia and diabetes are setting in at an alarming rate in many of the low- and medium-income countries also, particularly among their urban populations. Therefore, planning and implementing programmes for prevention of CVD, particularly for controlling risk factors like hyperlipidaemia and diabetes should be accorded high priority. [source]


The impact of climate change on birds

IBIS, Issue 2004
Humphrey Q. P. Crick
Weather is of major importance for the population dynamics of birds, but the implications of climate change have only recently begun to be addressed. There is already compelling evidence that birds have been affected by recent climate changes. This review suggests that although there is a substantial body of evidence for changes in the phenology of birds, particularly of the timing of migration and of nesting, the consequences of these responses for a species' population dynamics is still an area requiring in-depth research. The potential for phenological miscuing (responding inappropriately to climate change, including a lack of response) and for phenological disjunction (in which a bird species becomes out of synchrony with its environment) are beginning to be demonstrated, and are also important areas for further research. The study of climatically induced distributional change is currently at a predictive modelling stage, and will need to develop methods for testing these predictions. Overall, there is a range of intrinsic and extrinsic factors that could potentially inhibit adaptation to climate change and these are a high priority for research. [source]


Potentially Inappropriate Medication Utilization in the Emergency Department Visits by Older Adults: Analysis From a Nationally Representative Sample

ACADEMIC EMERGENCY MEDICINE, Issue 3 2010
William J. Meurer MD
Abstract Objectives:, The objectives were to determine the frequency of administration of potentially inappropriate medications (PIMs) to older emergency department (ED) patients and to examine recent trends in the rates of PIM usage. Methods:, The data examined during the study were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS). This study utilized the nationally representative ED data from 2000,2006 NHAMCS surveys. Our sample included older adults (age 65 years and greater) who were treated in the ED and discharged home. Estimated frequencies of PIM-associated ED visits were calculated. A multivariable logistic regression model was created to assess demographic, clinical, and hospital factors associated with PIM administration and to assess temporal trends. Results:, Approximately 19.5 million patients, or 16.8% (95% confidence interval [CI] = 16.1% to 17.4%) of eligible ED visits, were associated with one or more PIMs. The five most common PIMs were promethazine, ketorolac, propoxyphene, meperidine, and diphenhydramine. The total number of medications prescribed or administered during the ED visit was most strongly associated with PIM use. Other covariates associated with PIM use included rural location outside of the Northeast, being seen by a staff physician only (and not by a resident or intern), presenting with an injury, and the combination of female sex and age 65,74 years. There was a small but significant decrease in the proportion of visits associated with a PIM over the study period. Conclusions:, Potentially inappropriate medication administration in the ED remains common. Given rising concerns about preventable complications of medical care, this area may be of high priority for intervention. Substantial regional and hospital type (teaching versus nonteaching) variability appears to exist.

The emergence of social assistance in China

INTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 3 2006
Joe C.B. Leung
This article outlines the development of China's social assistance programme, including its design, implementation and trends. The Chinese government has given high priority to the establishment and institutionalisation of this programme. To have an effective social assistance programme in the context of an increasingly pluralistic society, China is facing the profoundly challenging task of designing a coherent and over-arching social protection system that would cover retirement, medical care, unemployment and poverty alleviation.

Surrogacy and persistence in reserve selection: landscape prioritization for multiple taxa in Britain

JOURNAL OF APPLIED ECOLOGY, Issue 1 2009
Aldina M. A. Franco
Summary 1A principal goal of protected-area networks is to maintain viable populations of as many species as possible, particularly those that are vulnerable to environmental change outside reserves. Ideally, one wants to be able to protect all biodiversity when selecting priority areas for conservation. 2Using the area-prioritization algorithm ZONATION, we identified the locations where UK Biodiversity Action Plan (BAP) species of mammals, birds, herptiles, butterflies and plants occur in concentrated populations with high connectivity. Both these features are likely to be correlated with population persistence. The analyses were successful in maintaining a high proportion of the connectivity of narrow-range species, and large total amounts of the connectivity of wider-range species over 10% of the land surface of Great Britain. 3Biodiversity Action Plan (BAP , high priority) species of one taxonomic group were not particularly good surrogates (indicators) for BAP species of other taxonomic groups. Hence, maintaining population concentrations of one taxonomic group did not guarantee doing likewise for other taxa. 4Species with narrow geographic ranges were most effective at predicting conservation success for other species, probably because they represent the range of environmental conditions required by other species. 5Synthesis and applications. This study identifies landscape-scale priority areas for conservation of priority species from several taxonomic groups, using the Zonation software. ,Indicator groups' were only partially successful as predictors of priority areas for other taxonomic groups, and therefore, the identification of priority areas for biodiversity conservation should include information from all taxonomic groups available. Larger areas should be protected to account for species not included in the analyses. Conservation solutions based on data for many different species, and particularly those species with narrowly defined ranges, appear to be most effective at protecting other rare taxa. [source]


A comparison of regeneration dynamics following gap creation at two geographically contrasting heathland sites

JOURNAL OF APPLIED ECOLOGY, Issue 5 2000
A.J. Britton
1.,Lowland Calluna -dominated heathlands are a high priority for conservation in Europe. As an anthropogenic subclimax community they require regular management intervention to maintain their conservation interest. 2.,Increasingly, Calluna is disappearing from lowland heathlands and being replaced by grasses, especially in the Netherlands and more recently in south-east England. While Calluna is highly competitive over much of its life cycle, its competitive ability is reduced during the regeneration phase that follows the death of stands or results from management activity. 3.,We examined the influence of five factors on regeneration of vegetation in gaps in two broadly similar lowland dry heaths over a 3-year period. These were: geographical location (combining a variety of environmental contrasts); dominant species (Calluna or grasses); management techniques; gap size; and seed source availability. 4.,Site location had the greatest effect on patterns of regeneration. Regeneration on the Wirral (north-west England) was faster and more dominated by Calluna than regeneration in Breckland (south-east England), which was dominated by other species including grasses and annual plants. Addition of Calluna seed at the Breckland site failed to increase Calluna cover. It was concluded that climatic or other environmental factors were the most probable cause of poor regeneration. 5.,Cover of grasses in regenerating areas was greatest in Breckland, where Deschampsia was able to establish in all gaps where there was a seed source (either in the surrounding vegetation or applied as a treatment). On the Wirral, Deschampsia establishment was limited, even in gaps where a seed source was applied. 6.,This work has implications for the conservation management of heathlands, which currently follows a standard prescription throughout the UK. It is suggested that management regimes should be tailored to suit the conditions prevailing at individual sites as regeneration dynamics may be extremely variable. [source]


Using Biomonitoring Equivalents to interpret human biomonitoring data in a public health risk context

JOURNAL OF APPLIED TOXICOLOGY, Issue 4 2009
Sean M. Hays
Abstract Increasingly sensitive analytical tools allow measurement of trace concentrations of chemicals in human biological media in persons from the general population. Such data are being generated by biomonitoring programs conducted by the US Centers for Disease Control and other researchers. However, few screening tools are available for interpretation of such data in a health risk assessment context. This review describes the concept and implementation of Biomonitoring Equivalents (BEs), estimates of the concentration of a chemical or metabolite in a biological medium that is consistent with an existing exposure guidance value such as a tolerable daily intake or reference dose. The BE approach integrates available pharmacokinetic data to convert an existing exposure guidance value into an equivalent concentration in a biological medium. Key concepts regarding the derivation and communication of BE values resulting from an expert workshop held in 2007 are summarized. BE derivations for four case study chemicals (toluene, 2,4-dichlorophenoxyacetic acid, cadmium and acrylamide) are presented, and the interpretation of biomonitoring data for these chemicals is presented using the BE values. These case studies demonstrate that a range of pharmacokinetic data and approaches can be used to derive BE values; fully developed physiologically based pharmacokinetic models, while useful, are not required. The resulting screening level evaluation can be used to classify these compounds into relative categories of low, medium and high priority for risk assessment follow-up. Future challenges related to the derivation and use of BE values as tools in risk management are discussed. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Roadside conditions as predictor for wildlife crossing probability in a Central African rainforest

AFRICAN JOURNAL OF ECOLOGY, Issue 2 2010
Christiaan A. Van Der Hoeven
Abstract The negative effects of roads on wildlife in tropical rainforests are poorly understood. Road construction has high priority in Africa, while negative impacts of roads on wildlife movement often are neglected. This study aims at providing information on the effects of roads on crossing behaviour of rainforest wildlife. The probability that wildlife would cross forest roads was analysed for association with ten different factors that were linked to road presence or construction. Factors were divided into three classes: vegetation cover, topography and human influence. A trackplot survey was done in southern Cameroon, Africa. Trackplots were laid along a 32 km unpaved logging road that intersects Campo-Ma'an National Park. Tracks of several species were found frequently (e.g. genets and porcupines); while others were found only sporadically (e.g. forest duikers and apes). The actual physical obstacles found along the road (e.g. logs, banks, etc.) were highly negatively correlated with crossing probabilities. For all wildlife species high vegetation cover was positively correlated to crossing probability. This study indicates that roads have a large impact on wildlife, and suggests which factors could be altered during road construction and maintenance in order to mitigate these impacts. Résumé Les effets négatifs des routes sur la faune sauvage des forêts tropicales sont mal compris. La construction de routes est une toute grande priorité en Afrique mais on néglige souvent les impacts négatifs des routes sur les déplacements de la faune. Cette étude cherche à fournir des informations sur les effets des routes sur les animaux des forêts pluviales qui les traversent. Nous avons analysé la probabilité que la faune traverse les routes en fonction de dix facteurs différents liés à la présence ou à la construction de routes. Ces facteurs furent divisés en trois classes: couverture végétale, topographie et influence humaine. Des parcelles échantillons furent définies dans le sud du Cameroun, Afrique pour y déceler les traces. Ces parcelles se trouvaient le long d'une piste forestière non macadamisée qui traverse le Parc National de Campo-Ma'an. On a souvent observé des traces de plusieurs espèces (ex. genettes et porcs-épics) alors que d'autres (ex. céphalophes de forêt et grands singes) ne se voyaient que sporadiquement. Les obstacles physiques rencontrés le long de la route (ex. troncs, remblais, etc.) étaient en forte corrélation négative avec la probabilité de traverser. Pour toutes les espèces sauvages, une végétation dense était positivement liée à la probabilité de traverser. Cette étude indique que les routes ont un grand impact sur la faune sauvage et indique quels facteurs pourraient être modifiés lors de la construction et de l'entretien des routes pour atténuer ces impacts.

Potentialities of multivariate approaches in genome-based cancer research: identification of candidate genes for new diagnostics by PLS discriminant analysis,

JOURNAL OF CHEMOMETRICS, Issue 3-4 2004
G. Musumarra
Abstract Partial least squares discriminant analysis (PLS-DA) provides a sound statistical basis for the selection, from an original 9605-data set, of a limited number of gene transcripts most effective in discriminating different tumour histotypes. The potentialities of the PLS-DA approach are pointed out by its ability to identify genes which, according to current knowledge, are associated with cancer development. Moreover, PLS-DA was able to identify MUC 13 and S100P proteins as candidates for the development of new colon cancer diagnostics. Various genes with unknown function and ESTs (expressed sequence tags), found to be important in discriminating genes for colon, leukaemia, renal and central nervous system tumour cells, are indicated as deserving high priority in future molecular studies.

Substance loss caused by scaling with different sonic scaler inserts , an in vitro study

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2001
Thomas Kocher
Abstract Background, aims: Depending on the phase of periodontal treatment, power-driven inserts with different power levels are necessary: during initial treatment and flap operations, it must be possible to remove calculus which firmly adheres to the root surface with great efficiency; in contrast, gentle root-surface instrumentation has a high priority during maintenance treatment. Recently, modified sonic scaler inserts have been introduced: diamond-coated inserts for open flap operations and slim probe-shaped sonic scaler inserts for deplaqueing during maintenance. Method: We compared the substance removal by these inserts to that of a conventional insert. In a bench system which allows application force, stroke height, and width and frequency of instrumentation to be monitored and also permits assessment of the topography before and after instrumentation (yielding depth removal and removed volume), we instrumented aluminum rods in triplicate and bovine roots in a 5-fold repetition. Results: With high application forces (1.0 N), the diamond-coated inserts removed 30 to 50% more substance than the conventional one. Except for the slim inserts, there was a significant linear relationship between increasing force and removed volume. Probe-shaped inserts do not remove considerable substance even with increasing pressures. Conclusions: Diamond-coated inserts remove tooth substance very effectively and must thus be handled with care: more pressure effects more removal. Probe-shaped inserts can be used without risk during maintenance visits. [source]


Intercultural Communication on Web sites: A Cross-Cultural Analysis of Web sites from High-Context Cultures and Low-Context Cultures

JOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 1 2005
Elizabeth Würtz
The aim of this study is to explore and identify the strategies used by high-context cultures in utilizing the Internet,a largely low-context medium,for communication and marketing purposes. It is hypothesized that individuals in high-context cultures are more likely to adopt the visual effects offered by the Internet to convey their messages efficiently than their low-context counterparts. How might high-context cultures make the most of the potentials offered by the Internet generation of today? Assuming that visual communication is a high priority in the design of high-context Web sites, how do the visual methods used on Web sites vary according to the communication styles in different cultures? Using Hall's high- and low-context dimensions as the main parameters, an exploratory analysis of McDonald's Web sites identified five different strategies by which visual communication is used to support high-context communication traits.

Field performance and seasonal changes in the efficacy against Helicoverpa armigera (Hübner) of transgenic cotton expressing the insecticidal protein vip3A

AGRICULTURAL AND FOREST ENTOMOLOGY, Issue 2 2007
Danny J. Llewellyn
Abstract 1,Three years of field experiments in Eastern Australia were carried out on transgenic cotton (Gossypium hirsutum L.) event Cot102 expressing the insecticidal protein gene vip3A from Bacillus thuringiensis to evaluate performance against Helicoverpa armigera Hübner. Efficacy, defined as the capacity of plant tissues to induce larval mortality, was determined with a well-validated leaf bioassay fortnightly through the growth cycle of the cotton in each season. 2,Cot102 plants proved highly efficacious against H. armigera, particularly early in the season, although their efficacy declined as the season progressed, in a manner similar to, but not as dramatic as, that observed with commercial Cry1Ac expressing cotton (Bollgard or Ingard cotton). 3,Field surveys indicated that very few larvae survived beyond first instar on intact growing plants. 4,In one season efficacy declined for a period of approximately 20 days after a cool wet period, suggesting that this may have had a detrimental effect on the expression or efficacy of the gene, but this will need to be verified in further replicated trials. 5,Quantitative enzyme-linked immunosorbent assays indicated that there was no dramatic reduction in production of the vip3A protein during growth and maturation of the crop, suggesting that other host plant factors were affecting the efficacy of the insecticidal protein in the insect gut. 6,These data indicate that Cot102 cotton would provide a useful alternative to Bollgard cotton but, given the similar lytic mode of action of vip3A proteins in the insect midgut, there may be similar inherent vulnerabilities to resistance evolution for these proteins if used alone. Pyramiding of the vip3A trait with a second insecticidal gene would appear to be a high priority for achieving sustainable deployment against H. armigera or similar susceptible species. [source]


The role of support staff in promoting the social inclusion of persons with an intellectual disability

JOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 8 2010
R. McConkey
Abstract Background Past studies have found that people supported in more individualised housing options tend to have levels of community participation and wider social networks than those in other accommodation options. Yet, the contribution of support staff in facilitating social inclusion has received relatively scant attention. Methods In all 245 staff working in either supported living schemes, or shared residential and group homes, or in day centres completed a written questionnaire in which they rated in terms of priority to their job, 16 tasks that were supportive of social inclusion and a further 16 tasks that related to the care of the person they supported. In addition staff identified those tasks that they considered were not appropriate to their job. Results Across all three service settings, staff rated more care tasks as having higher priority than they did the social inclusion tasks. However, staff in supported living schemes rated more social inclusion tasks as having high priority than did staff in the other two service settings. Equally the staff who were most inclined to rate social inclusion tasks as not being applicable to their job were those working day centres; female rather than male staff, those in front-line staff rather than senior staff, and those in part-time or relief positions rather than full-time posts. However, within each service settings, there were wide variations in how staff rated the social inclusion tasks. Conclusions Staff working in more individualised support arrangements tend to give greater priority to promoting social inclusion although this can vary widely both across and within staff teams. Nonetheless, staff gave greater priority to care tasks especially in congregated service settings. Service managers may need to give more emphasis to social inclusion tasks and provide the leadership, training and resources to facilitate support staff to re-assess their priorities. [source]

Summary This study investigates the barriers to the conduct of research as perceived by radiation therapists (RT) particularly with regards to their activity as part of collaborative clinical trials groups such as the Trans-Tasman Radiation Oncology Group. These were examined to identify solutions that might promote research by RT working within busy clinical services. In September to October 2005, surveys were sent to an RT Educator and RT Chiefs in four public hospitals in New South Wales, Australia, with a request to distribute and collect the surveys from RT employed at their centres. The overall response rate across these centres was 59% (78/133). Most of the respondents felt that their managers regarded research to be of high priority (79%) and that others in their workplace considered initiating and conducting research as important (79%). The RT considered lack of time during working hours to be the greatest barrier to research (87%). However, the RT felt that the availability of a research mentor would facilitate research in their workplace (90%). Based on our findings, the availability of structural support from radiation oncology centres may promote the clinical trials research participation of RT. [source]


Olfactory receptors: G protein-coupled receptors and beyond

JOURNAL OF NEUROCHEMISTRY, Issue 6 2009
Marc Spehr
Abstract Sensing the chemical environment is critical for all organisms. Diverse animals from insects to mammals utilize highly organized olfactory system to detect, encode, and process chemostimuli that may carry important information critical for health, survival, social interactions and reproduction. Therefore, for animals to properly interpret and react to their environment it is imperative that the olfactory system recognizes chemical stimuli with appropriate selectivity and sensitivity. Because olfactory receptor proteins play such an essential role in the specific recognition of diverse stimuli, understanding how they interact with and transduce their cognate ligands is a high priority. In the nearly two decades since the discovery that the mammalian odorant receptor gene family constitutes the largest group of G protein-coupled receptor (GPCR) genes, much attention has been focused on the roles of GPCRs in vertebrate and invertebrate olfaction. However, is has become clear that the ,family' of olfactory receptors is highly diverse, with roles for enzymes and ligand-gated ion channels as well as GPCRs in the primary detection of olfactory stimuli.

Anger and combat-related posttraumatic stress disorder

JOURNAL OF TRAUMATIC STRESS, Issue 2 2002
Raymond W. Novaco
Abstract We examined whether combat-related PTSD was differentially associated with particular dimensions of anger on two multi-index, psychometric instruments and whether the proportion of variation in PTSD scores explained by anger was significantly greater than that by demographic and exposure variables. We also examined the reliability and validity of a subset of Mississippi Scale items as an anger measure. Participants were 143 Vietnam combat veterans. Anger accounted for over 40% of the variance in Mississippi PTSD scores (minus the anger items) above that associated with age, education, and combat exposure. Veterans with structured-interview,diagnosed PTSD were significantly differentiated from those without PTSD on all anger indices. The results point to anger treatment as a high priority for combat-related PTSD. [source]


The management lessons learned from sediment remediation in the Detroit River , western Lake Erie watershed

LAKES & RESERVOIRS: RESEARCH AND MANAGEMENT, Issue 3-4 2004
John H. Hartig
Abstract During the 1970s,1990s, considerable emphasis was placed on minimizing the inputs of polychlorinated biphenyls (PCBs) from active sources. In addition, between 1993 and 2001, , $US130 × 106 was spent for sediment remediation within the western Lake Erie , Detroit River basin. In general, although PCB contamination of the Detroit River and Lake Erie declined significantly between the 1970s and mid-1990s, it has remained fairly stable over the past 10 years. Control of PCBs and other contaminants at their source remains a primary imperative for action. Remediation of contaminated sediments is growing in importance, however, as greater levels of source control are achieved. From a sediment management perspective, it is estimated that between 1993 and 2001 a substantially higher mass of PCBs (over two orders of magnitude higher) was removed as a result of contaminated sediment remediation, as compared to navigational dredging of shipping channels. In addition, there is a strong and compelling rationale for moving expeditiously to remediate severely contaminated sediment while it is still relatively contained in a small geographical area. The cost of not acting in a timely manner might be to exacerbate environmental problems including increased deformities and reproductive problems in wildlife, delayed ecosystem recovery and increased costs, or even preclusion of future sediment remediation. Based on discussions at a United States of America,Canada workshop held in 2002, key management advice includes continued emphasis to be placed on remediating contaminated sediment hot spots (including evaluating the effectiveness of projects), integrated monitoring efforts to be focused on beneficial use restoration and a high priority to be placed on sustaining and building upon modelling efforts, in order to be able to accurately predict and evaluate ecosystem responses to remedial and preventive actions.

Hepatic venous outflow obstruction in pediatric living donor liver transplantation using left-sided lobe grafts: Kyoto university experience,

LIVER TRANSPLANTATION, Issue 10 2010
Seisuke Sakamoto
The goals of this study were to evaluate the incidence of hepatic venous outflow obstruction (HVOO) in pediatric patients after living donor liver transplantation (LDLT) using left-sided lobe grafts and to assess the therapeutic modalities used for the treatment of this complication at a single center. Four hundred thirteen primary LDLT procedures were performed with left-sided lobe grafts between 1996 and 2006. All transplants identified with HVOO from a cohort of 380 grafts with survival greater than 90 days were evaluated with respect to the patient demographics, therapeutic intervention, recurrence, and outcome. Seventeen cases (4.5%) were identified with HVOO. Eight patients experienced recurrence after the initial balloon venoplasty. Two patients finally required stent placement after they experienced recurrence shortly after the initial balloon venoplasty. A univariate analysis revealed that a smaller recipient-to-donor body weight ratio and the use of reduced grafts were statistically significant risk factors. The cases with grafts with multiple hepatic veins had a higher incidence of HVOO. In conclusion, the necessity of repeated balloon venoplasty and stent placement was related to poor graft survival. Therefore, the prevention of HVOO should be a high priority in LDLT. When grafts with multiple hepatic veins and/or significant donor-recipient size mismatching are encountered, the use of a patch graft is recommended. Stent placement should be carefully considered because of the absence of data on the long-term patency of stents and stent-related complications. New stenting devices, such as drug-eluting and biodegradable stents, may be promising for the management of HVOO. Liver Transpl 16:1207,1214, 2010. © 2010 AASLD. [source]


Ecology and conservation of common bottlenose dolphins Tursiops truncatus in the Mediterranean Sea

MAMMAL REVIEW, Issue 2 2009
GIOVANNI BEARZI
ABSTRACT 1Bottlenose dolphins Tursiops truncatus are amongst the best-known cetaceans. In the Mediterranean Sea, however, modern field studies of cetaceans did not start until the late 1980s. Bottlenose dolphins have been studied only in relatively small portions of the basin, and wide areas remain largely unexplored. 2This paper reviews the ecology, behaviour, interactions with fisheries and conservation status of Mediterranean bottlenose dolphins, and identifies threats likely to have affected them in historical and recent times. 3Whilst intentional killing was probably the most important cause of mortality until the 1960s, important ongoing threats include incidental mortality in fishing gear and the reduced availability of key prey caused by overfishing and environmental degradation throughout the region. Additional potential or likely threats include the toxic effects of xenobiotic chemicals, epizootic outbreaks, direct disturbance from boating and shipping, noise, and the consequences of climate change. 4The flexible social organization and opportunistic diet and behaviour of bottlenose dolphins may allow them to withstand at least some of the effects of overfishing and habitat degradation. However, dolphin abundance is thought to have declined considerably in the region and management measures are needed to prevent further decline. 5Management strategies that could benefit bottlenose dolphins, such as sustainable fishing, curbing marine pollution and protecting biodiversity, are already embedded in legislation and treaties. Compliance with those existing commitments and obligations should be given high priority. [source]


Exploring the quality of dying of patients with chronic obstructive pulmonary disease in the intensive care unit: a mixed methods study

NURSING IN CRITICAL CARE, Issue 2 2009
Donna Goodridge
Abstract Rationale for the study:, Improving the quality of end-of-life (EOL) care in critical care settings is a high priority. Patients with advanced chronic obstructive pulmonary disease (COPD) are frequently admitted to and die in critical care units. To date, there has been little research examining the quality of EOL care for this unique subpopulation of critical care patients. Aims:, The aims of this study were (a) to examine critical care clinician perspectives on the quality of dying of patients with COPD and (b) to compare nurse ratings of the quality of dying and death between patients with COPD with those who died from other illnesses in critical care settings. Design and sample:, A sequential mixed method design was used. Three focus groups provided data describing the EOL care provided to patients with COPD dying in the intensive care unit (ICU). Nurses caring for patients who died in the ICU completed a previously validated, cross-sectional survey (Quality of Dying and Death) rating the quality of dying for 103 patients. Data analysis:, Thematic analysis was used to analyse the focus group data. Total and item scores for 34 patients who had died in the ICU with COPD were compared with those for 69 patients who died from other causes. Results:, Three primary themes emerged from the qualitative data are as follows: managing difficult symptoms, questioning the appropriateness of care and establishing care priorities. Ratings for the quality of dying were significantly lower for patients with COPD than for those who died from other causes on several survey items, including dyspnoea, anxiety and the belief that the patient had been kept alive too long. The qualitative data allowed for in-depth explication of the survey results. Conclusions:, Attention to the management of dyspnoea, anxiety and treatment decision-making are priority concerns when providing EOL care in the ICU to patients with COPD. [source]
