Plant food supplement (PFS) market structure in EC Member States, methods and techniques for the assessment of individual PFS intake

The popularity of herbal products, especially plant food supplements (PFS) and herbal medicine is on the rise in Europe and other parts of the world, with increased use in the general population as well as among specific subgroups encompassing children, women or those suffering from diseases such as cancer. The aim of this paper is to examine the PFS market structures in European Community (EC) Member States as well as to examine issues addressing methodologies and consumption data relating to PFS use in Europe. A revision of recent reports on market data, trends and main distribution channels, in addition an example of the consumption of PFS in Spain, is presented. An overview of the methods and administration techniques used to assess individual food consumption as a starting point, including their uses and limitations, as well as some examples of studies that collect Food Supplement (FS) information, including herbal/botanical/plant-derived products are also discussed. Additionally, the intake estimation process of food nutrients is described and used to propose the PFS ingredients intake estimation process. Nationally representative PFS consumption data is scarce in Europe. The majority of studies have been conducted in Scandinavia and the UK. However the heterogeneity of definitions, study design and objectives make it difficult to compare results and extrapolate conclusions.     

PEG based hyperbranched polymeric hollow nanospheres

The synthesis of a new PEG based hyperbranched copolymer of poly(ethylene glycol) methyl ether methacrylate-co-ethylene glycol dimethacrylate (PEGMEMA-co-EGDMA) was achieved via a one-step in situ deactivation enhanced atom transfer radical polymerization (DE-ATRP). Then, hollow PEG based nanospheres were fabricated from this polymer using a solvent evaporation method and post-stabilisation strategy. Furthermore, the analysis using a cellular metabolic activity assay proved that the copolymer did not affect cellular metabolism, indicating that this PEG based polymeric nanosphere has potential for use in drug delivery applications.     

The development and application of a proxy measure of alcohol-related traffic crashes for rural communities

Context

To date, no studies have adequately examined whether community-level, rather than individual-level, characteristics, are associated with high rates of alcohol-related traffic crashes (ARTC).

Objective

This study aims to identify a proxy measure of ARTC most appropriate to rural communities in New South Wales (NSW), Australia, and to identify community characteristics that predict higher rates of ARTC.

Methods

ARTC (2001–2007) incident data from 20 rural communities in NSW were obtained. Cost data were applied to take account of ARTCs of different severity.

Results

The method used to define a proxy measure of ARTCs for NSW generally was found to be inadequate when applied to local communities within NSW: specifically, two time periods were found to be alcohol-related for local communities only and seven time periods were found to be non-alcohol-related for local communities only. Applying a community-specific proxy measure of ARTCs to 20 communities identified substantial variation in ARTC cost-ratios, ranging from 1.20 to 0.15. Higher cost-ratios were statistically significantly predicted by the proportion of residents who were male and less than 25 years.

Conclusions

Proxy measures of ARTCs represent an ideal method of utilising routinely collected data to identify specific types of ARTCs that are most relevant to a defined community, identify community-specific factors associated with higher rates of ARTCs and measure the impact of interventions tailored to those risk factors. Such measures ought to be community-specific because these results suggest national or provincial-level definitions are not necessarily directly applicable to local communities. These results show substantial variability between communities in their rates of ARTC and identify communities with higher proportions of young males as being at increased risk.     

Relationship between persistent organic pollutants (POPs) and ranging patterns in common bottlenose dolphins (Tursiops truncatus) from coastal Georgia, USA

Bottlenose dolphins (Tursiops truncatus) are apex predators in coastal southeastern U.S. waters; as such they are indicators of persistent organic pollutants (POPs) in coastal ecosystems. POP concentrations measured in a dolphin's blubber are influenced by a number of factors, including the animal's sex and ranging pattern in relation to POP point sources. This study examined POP concentrations measured in bottlenose dolphin blubber samples (n = 102) from the Georgia, USA coast in relation to individual ranging patterns and specifically, distance of sightings from a polychlorinated biphenyl (PCB) point source near Brunswick, Georgia. Dolphin ranging patterns were determined based upon 5 years of photo-identification data from two field sites approximately 40 km apart: (1) the Brunswick field site, which included the Turtle/Brunswick River Estuary (TBRE), and (2) the Sapelo field site, which included the Sapelo Island National Estuarine Research Reserve (SINERR). Dolphins were categorized into one of three ranging patterns from photo-identification data. Individuals with sighting histories exclusively within one of the defined field sites were considered to have either Brunswick or Sapelo ranging patterns. Individuals sighted in both field sites were classified as having a Mixed ranging pattern. Brunswick males had the highest concentrations of PCBs reported for any marine mammal. The pattern of PCB congeners was consistent with Aroclor 1268, a highly chlorinated PCB mixture associated with a Superfund site in Brunswick. PCB levels in Sapelo males were lower than in Brunswick males, but comparable to the highest levels measured in other dolphin populations along the southeastern U.S. Female dolphins had higher Aroclor 1268 proportions than males, suggesting that the highly chlorinated congeners associated with Aroclor 1268 may not be offloaded through parturition and lactation, as easily as less halogenated POPs. Individuals sighted farther from the Superfund point source had lower Aroclor 1268 proportions.     

Hands-on Demonstrations: An Alternative to Full Scale Lab Experiments

Short demonstrations of basic fluid mechanics principles were developed for use in 50 minute seminar sessions, led by graduate student TA's. These have provided structured training for our TA's, lightened the load on our undergraduate lab facilities, and provided our students with visual, active learning opportunities. The demonstrations and handouts were developed by an undergraduate student as a summer project, and expanded on by successive TA's. The response from the students is best illustrated by the increase in seminar attendance from 30% to over 80%.     

Integrating natural language understanding with document structure analysis

Document understanding, the interpretation of a document from its image form, is a technology area which benefits greatly from the integration of natural language processing with image processing. We have developed a prototype of an Intelligent Document Understanding System (IDUS) which employs several technologies: image processing, optical character recognition, document structure analysis and text understanding in a cooperative fashion. This paper discusses those areas of research during development of IDUS where we have found the most benefit from the integration of natural language processing and image processing: document structure analysis, optical character recognition (OCR) correction, and text analysis. We also discuss two applications which are supported by IDUS: text retrieval and automatic generation of hypertext links     

Predictors and consequences of achievement goals in the college classroom: Maintaining interest and making the grade.

The authors investigated personality predictors of achievement goals in an introductory psychology class, as well as the consequences of these goals for the motivation and performance of 311 undergraduates. Two dimensions of achievement motivation (workmastery and competitive orientations; J. T. Spence & R. L. Helmreich, 1983) predicted the goals endorsed. Individuals high in workmastery were more likely to adopt mastery goals and less likely to adopt work avoidance goals, whereas competitive individuals were more likely to endorse performance and work avoidance goals. Students adopting mastery goals were more interested in the class, but students adopting performance goals achieved higher levels of performance. These results suggest that both mastery and performance goals can lead to important positive outcomes in college classes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Brief motivational interviewing in a hospital setting for adolescent smoking: A preliminary study.

This study tested the feasibility and efficacy of a brief smoking intervention for adolescents in a hospital seeing. Forty adolescent patients were randomized to receive either brief advice or a motivational interview, a nonconfrontational therapeutic intervention. Feasibility of brief smoking interventions with teen patients was supported by high rates of recruitment, retention, and quit attempts, and long periods of continuous abstinence. Although between-groups differences on smoking measures were not significant at 3-month follow-up, an effect size of h?=?.28 was noted. The sample showed significant decreases in smoking dependence and number of days smoked. Baseline stage of change, smoking rate, and depression were significant prospective predictors of smoking outcome. Implications for smoking intervention research with adolescents are discussed.

A partial test of the psychosomatic family model: Marital interaction patterns in asthma and nonasthma families.

The psychosomatic family model (PFM) implicates marital quality in childhood asthma chronicity and exacerbation. The PFM posits that the child's symptomatology varies in relation to parent interaction patterns characterized by conflict avoidance and brief intradyadic engagement. This investigation of 40 families sought to determine if marital dyads show differential conditional likelihoods for these behavioral characterizations as a function of having an asthmatic or nonasthmatic child. Using observational data collected in the home, a series of logit models examined the likelihood of extended dyadic engagement, disagreement, and child solicitation. As predicted, nonasthma couples were more likely to disagree and had longer intradyadic engagements, whereas asthma family couples were more solicitous. Contrary to expectation, marital quality was not a significant predictor of child solicitation in the asthma family couples. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
