Abstract
AIM To establish if detailed review of trauma reports with reference to coding manual improved accuracy of ISS and to establish if demonstrated changes in coding affected performance and tariff payment. MATERIALS AND METHODS A study was undertaken which gathered data from 6 months across the five trusts with information on imaging undertaken, mechanism of injury (MOI), Injury Severity Score (ISS), and injury descriptors was included. Patients with ISS near to a best practice tariff boundary of 9 and 16 (5-8 and 11-15) then had their imaging reviewed by the Radiology Department with direct reference to the ISS coding manual. Injuries were then re-coded and ISS recalculated. RESULTS Over the 6-month period, 1,693 patients were admitted to the database from the five hospitals. One hundred and sixty-nine (9.9%) patients met the inclusion criteria for review. Thirty-five (20.7%) had a change in abbreviated (region specific) injury code, with 30 a change in the resultant ISS. Three had a decrease in ISS and 27 increased ISS with all 27 moving across an ISS best practice tariff and three moving across two payment tariff boundaries. With re-coding, there was a potential £15,000 of lost revenue from the major trauma centre (MTC) alone. CONCLUSION Reporting with reference to ISS description improves the accuracy of ISS significantly. Radiologists improving the descriptions of specific injury patterns and adopting 'Trauma Audit and Research Network friendly' reporting strategies may improve data accuracy, performance, and payment of best practice tariffs to hospitals.

Abstract
BACKGROUND A validated geographic search filter for the retrieval of research about the United Kingdom (UK) from bibliographic databases had not previously been published. OBJECTIVES To develop and validate a geographic search filter to retrieve research about the UK from OVID medline with high recall and precision. METHODS Three gold standard sets of references were generated using the relative recall method. The sets contained references to studies about the UK which had informed National Institute for Health and Care Excellence (NICE) guidance. The first and second sets were used to develop and refine the medline UK filter. The third set was used to validate the filter. Recall, precision and number-needed-to-read (NNR) were calculated using a case study. RESULTS The validated medline UK filter demonstrated 87.6% relative recall against the third gold standard set. In the case study, the medline UK filter demonstrated 100% recall, 11.4% precision and a NNR of nine. CONCLUSION A validated geographic search filter to retrieve research about the UK with high recall and precision has been developed. The medline UK filter can be applied to systematic literature searches in OVID medline for topics with a UK focus.

Abstract
OBJECTIVE Colorectal cancer (CRC) has a substantial heritable component. Common genetic variation has been shown to contribute to CRC risk. A study was conducted in a large multi-population study to assess the feasibility of CRC risk prediction using common genetic variant data combined with other risk factors. A risk prediction model was built and applied to the Scottish population using available data. DESIGN Nine populations of European descent were studied to develop and validate CRC risk prediction models. Binary logistic regression was used to assess the combined effect of age, gender, family history (FH) and genotypes at 10 susceptibility loci that individually only modestly influence CRC risk. Risk models were generated from case-control data incorporating genotypes alone (n=39,266) and in combination with gender, age and FH (n=11,324). Model discriminatory performance was assessed using 10-fold internal cross-validation and externally using 4187 independent samples. The 10-year absolute risk was estimated by modelling genotype and FH with age- and gender-specific population risks. RESULTS The median number of risk alleles was greater in cases than controls (10 vs 9, p<2.2 × 10(-16)), confirmed in external validation sets (Sweden p=1.2 × 10(-6), Finland p=2 × 10(-5)). The mean per-allele increase in risk was 9% (OR 1.09; 95% CI 1.05 to 1.13). Discriminative performance was poor across the risk spectrum (area under curve for genotypes alone 0.57; area under curve for genotype/age/gender/FH 0.59). However, modelling genotype data, FH, age and gender with Scottish population data shows the practicalities of identifying a subgroup with >5% predicted 10-year absolute risk. CONCLUSION Genotype data provide additional information that complements age, gender and FH as risk factors, but individualised genetic risk prediction is not currently feasible. Nonetheless, the modelling exercise suggests public health potential since it is possible to stratify the population into CRC risk categories, thereby informing targeted prevention and surveillance.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVES The purpose of this investigation was to review the outcomes and safety of retrograde ureteroscopic laser lithotripsy (URS) for the treatment of urolithiasis in the spinal cord injury (SCI) population. SETTING Virginia, USA. METHODS All patients with SCI who underwent URS with holmium:YAG laser lithotripsy for urolithiasis over a 15-year period were identified. Stone size, location and number at presentation were recorded. Information regarding patient characteristics, intra-operative complications, surgical efficacy, stone clearance, peri-operative complications, and follow-up stone events was collected and analyzed. RESULTS A total of 67 URS procedures were performed on 29 SCI patients during the study period with an average follow-up of 3.4 years. Patients had an average of 2.3 ipsilateral ureteroscopies. The majority (85.1%) used indwelling catheters for long-term bladder management, and complete stone clearance after the first procedure was 34.3%. Of the 44 cases with residual stones >4 mm, 20 (45.5%) were secondary to technical or procedural limitations. The intra-operative complication rate was comparable to non-SCI studies at 1.5%, but peri-operative complications were significantly higher at 29.9% with the majority due to urosepsis. Factors associated with peri-operative complications include chronic obstructive pulmonary disease, motor incomplete injuries and lack of a pre-operative ureteral stent. CONCLUSION URS in the SCI population is an effective treatment for ureteral or renal stones but may be associated with greater risks and reduced efficacy.

Abstract
It is now recognised that a part of the inherited risk of colorectal cancer (CRC) can be explained by the co-inheritance of low-penetrance genetic variants. The accumulated experience to date in identifying these variants has served to highlight difficulties in conducting statistically and methodologically rigorous studies and follow-up analyses. The COGENT (COlorectal cancer GENeTics) consortium includes 20 research groups in Europe, Australia, the Americas, China and Japan. The overarching goal of COGENT is to identify and characterise low-penetrance susceptibility variants for CRC through association-based analyses. In this study, we review the rationale for identifying low-penetrance variants for CRC and our proposed strategy for establishing COGENT.

Abstract
6041 Background: Prognosis for recurrent or metastatic SCCHN patients remains poor with median survivals of 6–9 months. Therapies targeting this group are needed. We conducted a single arm Phase II trial of Ir plus CDDP in patients with recurrent or metastatic SCCHN. The goal of this trial was to evaluate the efficacy and toxicity of this combination in advanced SCCHN. Methods: Eligible patients had incurable SCCHN, an ECOG PS of 0–2 and were chemonaive (no prior chemotherapy or chemotherapy for primary disease at least 6 months prior to study entry). A two-stage accrual design (Simon) was used. Irinotecan 65 mg/m2 and CDDP 30 mg/m2 were administered weekly for 4 weeks, followed by a 2 week rest for a 6 week cycle. Due to GI toxicity and neutropenia, the Ir was decreased to 50 mg/m2 with CDDP 30 mg/m2. Response assessment was made after every cycle using WHO criteria. The primary endpoint was response rate. Results: Forty patients were enrolled (male: 33, female:7). Median age was 58 (33–79). Forty and 32 patients were evaluable for toxicity and response, respectively. Reasons for unevaluable: 7 without at least 1 full cycle of therapy; 1 patient with incomplete records. Overall response rate was 34% (11/32 PR) with 18% SD (6/32). Median progression free survival was 2.6 months. The median overall survival was 8.2 months. Toxicity was substantial at Ir 65 mg/m2 with a rate of Grade (G) 3 or 4 toxicity of 82% compared to 56% at Ir 50 mg/m2. For both dose levels, G 3 or 4 nausea and vomiting (23%), diarrhea (15%) and neutropenia (35%) were the most common toxicities. Conclusions: The combination of irinotecan and cisplatin is active in a poor prognosis group of patients. Toxicity of irinotecan at 65 mg/m2 with CDDP 30 mg/m2 is substantial. Irinotecan 50 mg/m2 and CDDP 30 mg/m2 is tolerable and provides a 34% response rate. No significant financial relationships to disclose.

Abstract
Chloroquine (CQ) resistance in Plasmodium falciparum has been associated with specific point mutations in the pfcrt and pfmdr-1 genes. In the present study, 30 children aged 1-12 years, who were all suffering from acute, uncomplicated, P. falciparum malaria in Ibadan, Nigeria, were evaluated to assess the association between these mutations and clinical outcome following treatment with CQ. The parasites, in blood samples collected pre-treatment and, in those who failed treatment, on the day symptoms re-occurred post-treatment, were genotyped using the polymorphic MSP1, MSP2 and GLURP loci and PCR-RFLP. The results showed that, pre-treatment, all 30 patients had polyclonal infections, the mean numbers of P. falciparum clones detected per infection being 2.6 with MSP1, 4.2 with MSP2 and 2.8 with GLURP. The T76 allele of pfcrt and the Y86 allele of pfmdr-1 were found in 53% and 40%, respectively, of the pre-treatment samples from the 15 patients who failed CQ treatment, but the Y1246 mutation in pfmdr-1 was never detected. Although the parasites from the two patients with high-grade (RIII) resistance to CQ had both of these point mutations, the presence of the T76 allele of pfcrt or the Y86 allele of pfmdr-1 (considered individually) could not be used to predict treatment outcome. However, a high frequency of clonal multiplicity may confound attempts to associate the point mutations in pfcrt or pfmdr-1 with clinical response to CQ. It remains unclear whether the present results represent the characteristics of the predominant parasite populations in the study area. Further studies are needed before the strength of the association between the point mutations identified as markers of drug resistance and clinical outcome can be accurately evaluated, in this and other regions of intense transmission.

Abstract
Circulating levels of insulin-like growth factor-I (IGF-I) and insulin-like growth factor-binding protein 3 (IGFBP-3) vary considerably between normal individuals. Recent epidemiological studies have provided evidence that these levels are predictive of risk of several common cancers. To evaluate possible sources of variation of the levels of circulating IGF-I and IGFBP-3 in females, we studied specific candidate genetic and nongenetic factors in 311 nulliparous, premenopausal Caucasian women, 17-35 years of age. Women who used oral contraceptives (OC) had reduced levels of IGF-I (269 versus 301 ng/ml; P = 0.001 adjusted for age) and increased levels of IGFBP-3 (4213 versus 4009 ng/ml; P = 0.002, adjusted for age) compared with nonusers. The ratio of IGF-I:IGFBP-3 was associated with the dose of estrogen contained in the OC (P(trend) = 0.006, adjusted for age). We identified a novel single bp polymorphism in the promoter region of the gene encoding IGFBP-3. This polymorphism was related to the level of IGFBP-3 in the circulation. Mean IGFBP-3 levels were 4390, 4130, and 3840 ng/ml for the AA, AC, and CC genotypes, respectively (P(trend) = 0.006, adjusted for age and OC use). We observed no effect of a recently described polymorphism in the promoter region of the gene encoding IGF-I on the plasma IGF-I level, but there was evidence for a modifying effect of this locus on the influence of OC on the IGF-I level. Our results support the view that circulating IGF-I levels and IGFBP-3 levels are complex traits and are influenced by a number of interacting genetic and nongenetic factors.

Abstract
Insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) is a major determinant of circulating levels of the IGFs and is clinically useful for the evaluation of GH deficiency and for predicting the response to GH treatment. Recent studies provide evidence that the circulating level of IGFBP-3 is inversely related to the risk of several common cancers, and that antiproliferative agents such as antiestrogens and retinoids act in part by up-regulating IGFBP-3 gene (IGFBP3) expression. Although approximately 50% of the substantial interindividual variability in circulating IGFBP-3 levels is known to have a genetic basis, the specific loci involved are unknown. Direct sequencing of genomic DNA specimens from a multiethnic population identified several single nucleotide polymorphisms in the promoter region of IGFBP3. For the most common single nucleotide polymorphism (nucleotide -202) found to be in Hardy-Weinberg equilibrium, genotype was highly correlated to circulating level of IGFBP-3 in 478 men from the Physicians' Health Study. In vitro, we documented significantly higher promoter activity of the A allele at the -202 locus compared with the C allele, consistent with the relationship observed between genotype and circulating IGFBP-3 (AA > AC > CC). A positive correlation was observed between circulating retinol levels and circulating IGFBP-3 levels; subset analysis by genotype showed that this relationship was only present among individuals carrying an A allele at -202 (AA > AC > CC). Tall individuals or individuals with a body mass index of 27 or greater had levels of circulating IGFBP-3 that were significantly higher when they possessed at least one A allele (AA > AC > CC). The IGFBP3 promoter region deserves investigation as a locus where polymorphic variation occurs frequently and may influence GH responsiveness, somatic growth, and possibly cancer risk.

Abstract
We demonstrate a simple all-optical realization of programmable edge enhancement and edge-enhanced correlation using novel photorefractive polymers. We show that the higher non-Bragg order in a two-beam coupling scheme contains the edge enhancement of the object when placed in the path of one of the incident beams. Also, this arrangement provides a scheme for writing joint transform correlation dynamic holograms, which can be read by a third beam. The correlation is edge enhanced, and the correlation peak increases with the applied bias voltage. Numerical results without and with beam fanning are presented. Theoretical predictions are reconciled with experimental results.

Abstract
Glycerol kinase (GK) represents the primary entry of glycerol into glucose and triglyceride metabolism. Impaired glucose tolerance (IGT) and hypertriglyceridemia are associated with an increased risk of diabetes mellitus and cardiovascular disease. The relationship between glycerol and the risk of IGT, however, is poorly understood. We therefore undertook the study of fasting plasma glycerol levels in a cohort of 1,056 unrelated men and women of French-Canadian descent. Family screening in the initial cohort identified 18 men from five families with severe hyperglycerolemia (values above 2.0 mmol/liter) and demonstrated an X-linked pattern of inheritance. Linkage analysis of the data from 12 microsatellite markers surrounding the Xp21.3 GK gene resulted in a peak LOD score of 3.46, centered around marker DXS8039. In addition, since all of the families originated in a population with a proven founder effect-the Saguenay Lac-St.-Jean region of Quebec-a common disease haplotype was sought. Indeed, a six-marker haplotype extending over a region of 5.5 cM was observed in all families. Resequencing of the GK gene in family members led to the discovery of a N288D missense mutation in exon 10, which resulted in the substitution of a highly conserved asparagine residue by a negatively charged aspartic acid. Although patients with the N288D mutation suffered from severe hyperglycerolemia, they were apparently otherwise healthy. The phenotypic analysis of the family members, however, showed that glycerol levels correlated with impaired glucose metabolism and body-fat distribution. We subsequently noted a substantial variation in glycerolemia in subjects of the initial cohort with normal plasma glycerol levels and demonstrated that this variance showed significant family resemblance. These results suggest a potentially important genetic connection between fasting glycerolemia and glucose homeostasis, not only in this X-linked deficiency but, potentially, in individuals within the "normal" range of plasma glycerol concentrations.

When filling important jobs, a good fit now works both ways. "Recruiting is an attitude," says one executive search pro. "And it's marketing." It's also equal parts horse sense, careful interviewing, and soul-searching. No matter how down-pat your organization's recruiting process, a refresher will keep you on your toes and a bad fit from disrupting your strategy--or your sleep.

Abstract
This paper reports on the findings of the largest ever European survey of female patients' perceptions of their cancer treatment. It has provided clarification of what women consider important in relation to their management and has identified several areas where more research is needed. It has shown that women's knowledge about cancer before diagnosis is poor and the number undergoing regular screening could be improved. Women are not being adequately prepared and educated about what to expect from treatment and steps should be taken as a matter of urgency to redress this shortcoming. It was revealed that whilst families were the primary source of support to female cancer patients, women also derive considerable support from healthcare professionals, particularly senior doctors; more attention should be paid by specialists and nurses to developing psychological skills to cope with this. In this context, further research is needed into how support groups may best meet patient needs.

Abstract
Spending on staff training in health care lags behind other fields, but several hospitals are getting ahead of the curve with innovative programs. They're offering classes to department managers, clinicians, even housekeeping staff. "Before, we were considered managers without brains," says the education coordinator at one hospital. "Now you have ownership, responsibility, and authority. The morale at the hospital is the best it's ever been."

Abstract
National legislation is just one sign of changing attitudes about safety needles. Fifteen states are considering similar bills; five already have passed such laws. OSHA also says it will put needlestick injuries on its agenda this fall. Yet if needlesticks and efforts to prevent them are nothing new, what's causing this change of heart? Two things: improved technology and media attention.

Evidence for host-specific clades of tetraphyllidean tapeworms (Platyhelminthes: Eucestoda) revealed by analysis of 18S ssrDNA. Int J Parasitol 1999; 29:1465-76.

Abstract
Sequence data from the V4 and V7-V9 variable regions of the 18S small subunit ribosomal DNA (ssrDNA) gene were used to examine relationships among 26 tetraphyllidean and two lecanicephalidean taxa. Newly collected specimens of 21 of the tetraphyllidean species were used to generate ssrDNA sequences that were combined with sequences previously available, including those of two diphyllidean taxa used for outgroup rooting. The sequences were aligned by eye according to secondary structural motifs of the conserved core of the molecule. Of the 1520 sites in the alignment, 874 (58%) were excluded from analysis due to alignment gaps and lack of positional homology as inferred by manual inspection. Genetic variability of the ssrDNA gene regions compared was greater than would be expected, based on the present taxonomy of the ingroup species, and the genetic divergences among tetraphyllidean 'families' and genera were comparable to that among tapeworm orders. Phylogenetic hypotheses were generated by the methods of maximum parsimony and maximum likelihood (GTR + I + Gamma nucleotide substitution model). Four most parsimonious trees resulted from analysis by maximum parsimony. Strict consensus of the four trees supported the monophyly of the Tetraphyllidea, with the lecanicephalidean taxa forming a sister lineage. Among the tetraphyllidean taxa included in the analysis were three major clades: a basal clade including species of the phyllobothriid genera Anthocephalum, Echeneibothrium, Rhinebothrium, Rhodobothrium and Spongiobothrium; a clade uniting the phyllobothriids of the genus Duplicibothrium with the dioecotaeniid genus Dioecotaenia; and a larger sister clade to the Duplicibothrium + Dioecotaenia clade that included the phyllobothriid genera Caulohothrium, Ceratobothrium, Clistobothrium, Paraoryigmatobothrium and Prosobothrium, the litobothriid genus Litobothrium and the onchobothriid genera Acanthobothrium, Calliobothrium, Phoreiobothrium and Platybothrium. Maximum likelihood analysis resulted in a topology that was congruent where nodes were strongly supported by parsimony analysis, but differed in the relative positions of the well-supported clades. In addition,maximum likelihood analysis grouped the lecanicephalidean taxa among the tetraphyllidean taxa, indicating paraphyly of the order Tetraphyllidea as currently defined. Relationships suggested by both methods of analysis reflected common host associations of the taxa better than their current classification, suggesting that coevolution has had a significant role in the evolution of the group.

Abstract
With hospital quality programs, the reach is broad, not deep. So says the National Hospital Quality Improvement Survey, conducted by health care researcher Stephen Shortell for Arthur Andersen and the American Hospital Association. Though 93 percent of responding hospitals and health systems use CQI and TQM methods is some fashion, they've taught them to only 35 percent of employees and a scant 22 percent of doctors on their medical staffs. Those poor showings leave health care lagging behind most other industries.

Abstract
At first, the retreat of practice management companies looked like a great opening for hospitals. What better way to acquire prime medical groups from motivated sellers? Trouble is, you still need a motivated buyer. That's why some observers contend hospitals will purchase only a fraction of medical groups being divested by MedPartners and other retrenching firms.

Abstract
The collection of familial data is an essential step for community genetics programs or genetic research. Ethical issues concerning privacy and confidentiality present a major challenge in such programs. In order to keep familial data confidential, we have developed a family-based numerical coding procedure which allows the use of confidential data and the determination of familial relationships without risk of disclosure. This procedure is composed of two parts: the physical separation of identifying information and individual data; and the use of a code containing all the information required to build family trees. This procedure has been used in Eastern Quebec since 1995, mainly for screening, genetic counseling, research on familial dyslipidemias, public health intervention, and research projects on the genetics of complex traits, such as arterial hypertension and coronary artery disease.

Leave it to the market. It's our collective corrective, the American way of problem-solving. So it's no surprise that we looked to the market to stop runaway health care costs. For awhile, it seemed to work. Medicare HMOs, physician practice management, risk contracting, and other innovations boomed. Then came the setbacks, exposing health care's complexities and contradictions--and reminding us that nothing escapes market discipline.

Familial eosinophilia maps to the cytokine gene cluster on human chromosomal region 5q31-q33. Am J Hum Genet 1998; 63:1086-94.

Abstract
Familial eosinophilia (FE) is an autosomal dominant disorder characterized by peripheral hypereosinophilia of unidentifiable cause with or without other organ involvement. To localize the gene for FE, we performed a genomewide search in a large U.S. kindred, using 312 different polymorphic markers. Seventeen affected subjects, 28 unaffected bloodline relatives, and 8 spouses were genotyped. The initial linkage results from the genome scan provided evidence for linkage on chromosome 5q31-q33. Additional genotyping of genetic markers located in this specific region demonstrated significant evidence that the FE locus is situated between the chromosome 5q markers D5S642 and D5S816 (multipoint LOD score of 6.49). Notably, this region contains the cytokine gene cluster, which includes three genes-namely, those for interleukin (IL)-3, IL-5, and granulocyte/macrophage colony-stimulating factor (GM-CSF)-whose products play important roles in the development and proliferation of eosinophils. These three cytokine genes were screened for potential disease-specific mutations by resequencing of a subgroup of individuals from the present kindred. No functional sequence polymorphisms were found within the promoter, the exons, or the introns of any of these genes or within the IL-3/GM-CSF enhancer, suggesting that the primary defect in FE is not caused by a mutation in any one of these genes but, rather, is caused by another gene in the area.

Abstract
A set of twelve specially doped lithium niobate crystals were grown to test the effect of the dopant on holographic recording in the crystals via the photorefractive effect. The crystals were doped with Ce, Co, Cr, Cu, Fe, Mn, Ni, Rh, Tb, Fe:Ce, Fe:Cr, and Fe:Mn. The transmission spectra was measured for each crystal and holograms have been written in each of the crystals with wavelengths from 457 nm to 671 nm. The wavelength sensitivity, scattering, and stability of the holograms varied substantially among the crystals. A qualitative description of the hologram's properties and a comparison of sensitivities between the crystals will be presented.
