Automatic Acquisition of Synonym Resources and Assessment of their Impact on the Enhanced Search in EHRs
Authors: Varoutas P.-C. , Rizand P. , Livartowski A. , Hamon T. , Grabar N. 
Published: February 2009

Summary
Objective: Currently, the use of natural language processing (NLP) approaches in order to improve search and exploration of electronic health records (EHRs) within healthcare information systems is not a common practice. One reason for this is the lack of suitable lexical resources. Indeed, in order to support such tasks, various types of such resources need to be collected or acquired (i.e., morphological, orthographic, synonymous).
Methods: We propose a novel method for the acquisition of synonymy resources. This method is language-independent and relies on existence of structured terminologies. It enables to decipher hidden synonymy relations between simple words and terms on the basis of their syntactic analysis and exploitation of their compositionality.
Results: Applied to series of synonym terms from the French subset of the UMLS, the method shows 99% precision. The overlap between thus inferred terms and the existing sparse resources of synonyms is very low. In order to better integrate these resources in an EHR search system, we analyzed a sample of clinical queries submitted by healthcare professionals.
Conclusions: Observation of clinical queries shows that they make a very little use of the query expansion function, and, whenever they do, synonymy relations are rarely involved.
Consent-based Access to Core EHR Information
Authors: Berntsen K. E. , Heimly V. 
Published: February 2009

Summary
Objective: Lack of access to updated drug information is a challenge for healthcare providers in Norway. Drug charts are updated in separate EHR systems but exchange of drug information between them is lacking. In order to provide ready access to updated medication information, a project for consent-based access to a core EHR has been established.
Methods: End users have developed requirements for additions to the medication modules in the EHR systems in cooperation with vendors, researchers and standardization workers. The modules are then implemented by the vendors, tested in the usability lab, and finally tested by the national testing and approval service before implementation. An ethnographic study, with focus on future users and their interaction with other actors regarding medicines and medication, has included semi-/unstructured interviews with the involved organizational units.
Results: The core EHR uses the EHR kept by the patient’s regular GP as the main source of information. A server-based solution has been chosen in order to keep the core EHR accessible outside the GP’s regular work hours. The core EHR is being tested, and the EHR-vendors are implementing additions to their systems in order to facilitate communication with the core EHR. All major EHR-system vendors in Norway participate in the project.
Conclusions: The core EHR provides a generic basis that may be used as a pilot for a national patient summary. Examples of a wider use of the core EHR can be: shared individual plans to support continuity of care, summary of the patient’s contacts with health providers in different organizations, and core EHR information such as important diagnoses, allergies and contact information. Extensive electronic cooperation and communication requires that all partners adjust their documentation practices to fit with other actors’ needs. The implementation effects on future work practices will be followed by researchers.
Definitions and Qualifiers in SNOMED CT
Authors: Cornet R. 
Published: February 2009

Summary
Objectives: An important feature of SNOMED CT is post-coordination, which is enabled by the SNOMED CT representation specifying whether a relationship is a defining or a qualifier relationship. In this paper the use of qualifier relationships in SNOMED CT is analyzed, as well as the extent to which qualifiers interact with defining relationships, so that pre-coordinated concepts can also be post-coordinated.
Methods: The July 2007 release of SNOMED CT was imported into a database. Analyses were performed by querying this database.
Results: Qualifier relationships occur in 10 out of 61 types of attribute relationships, and it is shown that generally pre-coordinated concepts cannot be constructed by applying post-coordination using qualifier relationships. Most of the qualifier relationships have generic target concepts, making it possible to construct concepts which are not clinically sensible. A logic-based representation is proposed to overcome the drawbacks of the current model.
Conclusions: Defining and qualifier relationships both enable post-coordination in SNOMED CT. Introducing qualifiers for more types of relationships, and using qualifier relationships with more specific target concepts will further improve post-coordination in SNOMED CT.

Some affected variables of information needs occurrence of an information seeker: a comprehensive hypothetical model
Authors: Karunanayeke KGDA , Nagata Haruki 
Published: February 2009

Affected variables of information needs occurrence of an information seeker which discussed in this paper are an important research area of the user studies. This paper is drawn on literary reviews focusing, in particularly the information needs concepts, theories, and its affected variables which explored the cognitive metaphors and methods. Even though researchers reviewed a range of several existing published pieces of literature on the target topic, the main objective of this paper is to discuss the key concepts of information needs from different angles to unify the concept of information needs through a new dimension while designing a very comprehensive hypothetical model of information needs occurrences. This paper found that information needs occurrences happen through a complex process of involving the individual's insufficient knowledge structure. The complexity arose due to two kind of basic variables such as cognitive and socio variables. The problem of insufficient knowledge became apparent when a variety of void areas were identified in the current state of knowledge. These voids were identified through cognitive environment. The cognitive variables were found as a set of features which expresses the individual's knowledge identity and capacity. This paper suggests that some specific cognitive factors such as skill factors, knowledge factors and psychological statuses of the overall intellectual power which affected with the insufficient needs. In this context, different avenues of information needs occurrences were discussed in order to identify the nature of the needs and the characteristics involved with that process.

Authors: Punchihewa CND , Jayasuriya Sumana 
Published: February 2009

The objective of this case study was to explore the use of online databases, user perception towards online databases, user satisfaction with facilities provided by the library for using online resources. The participants of the user survey were dawn from four categories of the University; academic staff members, postgraduate students, undergraduate students and students of Institute of Technology - University of Moratuwa (ITUM). Total of 400 participants were selected for the survey. Analysis confirmed that frequency of use of electronic databases have been restricted only to few data bases (Blackwell Synergy, Science Direct and Wiley Inter Science). Relatively a lesser usage level was observed for the online journals compared to print journals. User groups have satisfied with the programmes conducted for promoting online resources. They have highlighted different areas that should be improved by the library. Providing printing facility and offering remote access facility were main requests of the users. Academic members and postgraduate students had higher online resource usage than the undergraduate students and ITUM students. The major problems examined within the study included, lack of computer and Internet facilities, lack of awareness to electronic resources provided by the library, ineffective communication channels, and irrelevancy of articles in the provided databases and inefficient support of the library.

Coexistence of an unbalanced chromosomal rearrangement and spinal muscular atrophy in an infant with multiple congenital anomalies
Authors: Ben‐Shachar Shay , Bidwa Bhattacharjee M. , Potocki Lorraine , Lalani Seema R. 
Published: February 2009

AbstractUnbalanced chromosomal abnormalities are frequent and account for about 10% of all chromosomal abnormalities identified in live births. Diagnosis of a coinherited neuromuscular genetic disorder in these individuals is often challenging based on the severity and variability of the phenotype resulting from the genomic imbalance. Herein, we report on a 4‐month‐old male with multiple congenital anomalies, craniosynostosis, dysmorphic features, and hypotonia. Karyotype analysis revealed an abnormal male karyotype: 46,XY,der(3)(3;7)(p25;q36), with partial monosomy of 3pter and partial trisomy of 7qter. The targeted array‐based comparative genomic hybridization (array‐CGH) validated the cytogenetic abnormality, with further elucidation of trisomy of the Sonic Hedgehog (SHH) locus on chromosome 7. Based on the severity of hypotonia in this infant, molecular analysis for spinal muscular atrophy (SMA) was performed and the common homozygous deletion of exon 7 in the survival of motor neuron 1 gene (SMN1) was identified. This case demonstrates the challenges in diagnoses of coexisting genetic disorders in infants with neuromuscular disease. A high index of suspicion in such cases is essential for appropriate case management and family risk assessment. © 2009 Wiley‐Liss, Inc.
A novel approach for the kinetic and mechanistic modeling of acid‐catalyzed degradation of polymers
Authors: Lin Y.‐H. , Yang M.‐H. 
Published: February 2009

AbstractA new approach is presented that combines kinetic and mechanistic considerations which take into account chemical reactions and catalyst deactivation in the modeling of the catalytic degradation of polymers. Though acid‐catalyzed hydrocarbon cracking reactions involve a large number of compounds, reactions and catalyst deactivation and are very complex, the model gives a good representation of experimental results from the degradation of polypropylene over fluidized acidic catalysts. This model provides the benefits of product selectivity for the chemical composition, such as alkanes, alkenes, aromatics and coke, in relation to the effect of structurally different polymer feeds, and the performance of the catalyst used. It is an improvement of the currently available empirical ‘lumping’ techniques which usually are severely restricted in terms of product definitions.

Anticorrosive properties of epoxy resin coatings cured by aniline/p‐phenylenediamine copolymer
Authors: Yao Bin , Wang Gengchao , Li Xingwei , Zhang Zhiping 
Published: February 2009

AbstractAniline/p‐phenylenediamine copolymer [poly(ANI‐co‐p‐PDA)] was prepared by chemical oxidative polymerization. FTIR and 1H‐NMR analysis indicate that the poly(ANI‐co‐p‐PDA) is oligomer with end‐capped amino groups, which can cure epoxy resin. The anticorrosion performance of carbon steel (CS) samples coated by epoxy resin coating cured with poly(ANI‐co‐p‐PDA) and epoxy resin coating cured with triethylenetetramine exposed to 5 wt % NaCl and 0.1 mol/L HCl aqueous solution is studied by the potentiodynamic polarization and electrochemical impedance spectroscopy. The results show that the CS coated by epoxy resin coating cured with poly (ANI‐co‐p‐PDA) has more excellent corrosion protection than that of epoxy resin coating cured with triethylenetetramine. Raman spectroscopy analysis indicates that the surface of CS coated by epoxy resin coating cured with poly(ANI‐co‐p‐PDA) forms passive layer, which is composed of α‐Fe2O3. © 2009 Wiley Periodicals, Inc.

Published: February 2009

AbstractPoly(ethylene terephthalate) (PET) had been compounded with antibacterial materials for preparing antibacterial masterbatch using a twin‐screw extruder. Composite antibacterial PET fibers were prepared using the antibacterial masterbatch and pure PET resin by high‐speed melt‐spinning device, with spinning rate 3500 m/min. The antibacterial PET fibers of 5 wt % antibacterial materials were very effective against tested germs, with antibacterial ratios more than 90%, and had well mechanical properties. Scanning electron microscopy micrograph shows that antibacterial materials have been well dispersed in PET matrix. Microstructure of composite antibacterial fibers was studied by X‐ray diffraction, and the nucleating effect of antibacterial materials in the cooling crystallization process of PET was confirmed by differential scanning calorimetry (DSC). Result of thermogravimetry (TG) result shows that the addition of antibacterial materials accelerated the degradation of PET. The aged properties of antibacterial fibers were evaluated. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Photoinduced antimicrobial polymer blends with benzophenone as a functional additive
Authors: Hong Kyung Hwa , Sun Gang 
Published: February 2009

AbstractBenzophenone (BP)‐incorporated polymer films including polystyrene (PS), polyethylene (PE), polypropylene (PP), and polyvinyl alcohol (PVA) films were prepared, and the structural and photoactivated properties were investigated by SEM, XRD, DSC, antimicrobial, and hydrogen peroxide (H2O2) production tests. When the amount of incorporated BP concentration was 0.5 wt %, the polymer films were successfully prepared without significant changes in physical properties. Also, all the BP‐incorporated polymer films showed antimicrobial abilities under UVA (365 nm) irradiation, and the effectiveness increased as the amounts of BP in the polymers are increased. On the other hand, it was observed that photoirradiated PVA/BP composite films created H2O2 under the atmospheric dark condition. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Estimation of solubility parameter components of solutes and polymers using heat of vaporization and heat of sorption of solutes
Authors: Huang Jan‐Chan 
Published: February 2009

AbstractIn a recent study, a two‐dimensional solubility parameter model was used to correlate the heat of solution for solutes ranging from n‐alkanes to alcohols, dissolved in isotatic polypropylene (PP), poly(ethyl ethylene) (PEE), and poly(dimethylsiloxane) (PDMS). When literature data of solubility parameter components of solutes were used, the correlation had some scattering for solutes with low values of cohesive energy density. In this study, the components of solubility parameters of solutes and polymers were estimated from cohesive energy and heat of sorption of solutes. Good correlation was obtained for the specific heat of sorption (ΔUsorp/V) for solutes ranging from n‐alkanes to alcohols, and PDMS had a polar component as previously estimated. Free volume effect in solution process may be the source of a small systematic deviation from the model. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Measurements of birth defect prevalence: Which is most useful as a comparator group for pharmaceutical pregnancy registries?
Authors: Scheuerle Angela , Vannappagari Vani X. , Miller Mary K. 
Published: February 2009

AbstractPharmaceutical pregnancy registries document birth defects and other complications reported in pregnancies exposed to specific medications or diseases. A baseline estimate of birth defect prevalence is necessary for comparison. To identify potential teratogenic signals, the pregnancy registry must have a comparator that most closely matches the exposed population and data collection methodology, which are characteristics that vary among the multiplicity of birth defect surveillance systems. The system that yields the most accurate prevalence data may be different from that most closely matching the pregnancy registry methods. State public health programs have highly accurate and precise statistics, but their populations are broader than those of a pharmaceutical pregnancy registry. Large collaborative databases may have a more useful covered population, but there are secondary problems related to data precision. Health care databases enroll large numbers of patients and have good information about exposures and health problems, but the data can be difficult to access and lack useful detail. Exposure‐related databases are closer in population definition and collection methods, though the presence of different diseases and exposures can be problematic. Internal comparators are likely to be most useful in formal statistical analysis, but added cost and management burden and may require significantly increased registry enrollment. There is no ideal comparator, and this must be taken into account when planning a single‐exposure or single‐disease pregnancy registry. Birth Defects Research (Part A), 2009. © 2009 Wiley‐Liss, Inc.
