Abstract
The number of breast cancer patients who are informed about and have contact with patient self-help groups (SHGs) during their hospital stay varies across hospitals. The aim of this study is to investigate which patient and hospital characteristics contribute to these differences. Multilevel regression analysis was applied, using data on hospital characteristics and data from a patient survey, which catalogued the disease and socio-demographic characteristics of newly diagnosed breast cancer patients, and recorded if they were informed about and had contact with SHGs during their hospital stay. Data from 2639 patients from 82 hospitals were analysed. The odds of being informed about SHGs were significantly lower if patients were treated at a teaching hospital. Patients aged 40 to 59 years significantly more often reported that they were informed about SHGs than patients aged 60 to 69 years. Patients with the highest education certificates significantly more often reported that they both were informed about and have had contact with SHGs. These results suggest that in teaching hospitals, information provided to patients about SHGs is reduced. Furthermore, patients are differentially given information about SHGs and have different levels of contact with SHGs, based on their age and education.

Abstract
The sintered Ca(1-x-y)Dy(x)CeyMnO3 bodies were a single phase with a perovskite structure without any impurity phases. The calculated crystallite sizes of the Ca(1-x-y)Dy(x)CeyMnO3 were in the range of 43.3 to 63.3 nm. The composition significantly affected their microstructural and thermoelectric characteristics. The doped Dy led to both an increase in the electrical conductivity as well as the absolute value of the Seebeck coefficient, resulting in an enhanced power factor. The highest power factor (5.1 x 10(-4) Wm(-1) K(-2)) was obtained for Ca(0.8)Dy(0.2)MnO3 at 800 degrees C. In this study, we systematically discussed the thermoelectric properties of the Ca(1-x-y)Dy(x)CeyMnO3, with respect to the substitution of Dy and/or Ce for Ca.

Abstract
Visceral sensory afferents during disease or following injury often produce vague, diffuse body sensations, and pain referred to somatic targets. Alternatively, injury due to trauma or disease of somatic nerve targets can also lead to referred pain in visceral targets via a somatovisceral reflex. Both phenomenons are thought to be due to convergence of visceral and somatic afferents within the spinal cord. To investigate a potential peripheral influence for referred pain in visceral targets following somatic nerve injury, we examined whether a sciatic nerve injury known to produce hindpaw tactile hyperalgesia alters the frequency of micturition and the sensitivity of bladder-associated sensory neurons to pro-nociceptive chemokines. Adult female Sprague-Dawley rats received injections of cholera toxin B subunit conjugated to 555 into urinary bladder wall to retrogradely label visceral primary afferent neurons. After 7 days, the right sciatic nerve of these animals was subjected to a lysophosphatidylcholine (LPC)-induced focal demyelination injury. Pre- and post-injury tactile sensitivity in the hind paw and micturition frequency were assayed. Animals were allowed to survive for 14-28 days. Lumbosacral and lumbar dorsal root ganglia (DRG) ipsilateral to the nerve injury were acutely dissociated from sham and nerve injured animals. Bladder wall-associated sensory neurons identified via the retrograde marker were assayed for fluxes in intracellular calcium following administration of pro-nociceptive chemokines. The assayed chemokines included monocyte chemoattractant protein-1 (MCP1/CCL2) and stromal cell derived factor-1 alpha (SDF1/CXCL12). LPC nerve injured animals exhibited tactile hyperalgesia and increased micturition frequency for at least 28 days. Focal demyelination of the sciatic nerve also increased the number of injured L₄L₅ and non-injured L₆-S₂ bladder-associated sensory neurons that responded to MCP1 and SDF1 when compared with sensory neurons derived from uninjured naïve and sham-injured control animals. Taken together, these data suggest that some visceral hypersensitivity states may have a somatic origin. More importantly, nociceptive somatovisceral sensation may be mediated by upregulation of chemokine signaling in visceral sensory neurons.

Abstract
AIM OF THE STUDY Worksite health management (WHM) can positively influence employee health and performance. However, it has not yet been comprehensively implemented in companies. This study aims to identify the role of organisational structures in the implementation of WHM. METHODS In this cross-sectional study, data were collected on the companies' WHM and the organisational structure. Out of 522 randomly selected companies within the German information technology and communication (ITC) sector, one managing director for each company was being questioned through telephone interviews. Bivariate and multivariate logistic regression analyses were conducted. RESULTS The results of the study reveal that the implementation of WHM is positively correlated with a large company size (OR 2.75; 95%-CI 1.10-6.88) and with the existence of an employee representation (OR 2.48; 95%-CI 1.54-3.98). Other structural characteristics, such as the employment of a company physician, the percentage of temporary workers as well as the staff's age and sex distribution do not seem to have a significant impact on the implementation of WHM. CONCLUSIONS The results indicate that the implementation of WHM can only be explained to a certain degree by organisational structures. However, the findings highlight the fact that companies with few structural resources are in particular need of tailored support when implementing WHM.

Abstract
58 Background: Multiple treatment options now exist for metastatic CRPC patients (pts). Germ-line SNPs in docetaxel (D) transport, metabolism, binding site, and degradation genes may contribute to variability in outcomes observed in D treated CRPC pts. Methods: Between 1/07 and 10/08, all PCa pts seen in the Indiana University Simon Cancer Center oncology clinics were approached for recruitment to the Prostate Cancer Genetic Risk Evaluation of SNPs Study (PROGRESS). Participants completed a demographic and clinical questionnaire and provided a blood sample. Only CRPC pts treated with D were included in this analysis. Germ-line DNA was analyzed for SNP genotyping on a 128-SNP chip using a TaqMan OpenArray GT Kit (Applied Biosystems). The chip included genes critical to D signaling, transport, and elimination with minor allele frequencies > 5%. Pts were followed for progression-free (PFS) and overall survival (OS). Univariable analyses were performed to identify significant associations between SNP genotype, clinical parameters, and PFS and OS outcomes. Results: 60 pts with metastatic CRPC initiated on D enrolled. Demographics included: age (median) – 69 yrs, ECOG PS 0– 40%, prostate specific antigen (PSA) (median) – 129.9 ng/ml, PSA doubling time (median) – 1.8 months, visceral mets –25%. No clinical parameters were associated with PFS and OS. Significant SNP associations are summarized below. Conclusions: Differences in germ-line ABCG2, ABCB1, and TUBB4 SNPs may contribute to variation in clinical outcomes in CRPC pts treated with D. [Table: see text] [Table: see text]

Abstract
51 Background: Significant variation in response duration and overall survival exists among prostate cancer (PCa) patients treated with ADT. Germ-line SNPs affecting function of genes critical to hormone synthesis, transport, metabolism, binding sites, and degradation may contribute to variability in clinical outcomes observed in PCa patients treated with ADT. Methods: Between 1/07 and 10/08, all PCa patients seen in the Indiana University Simon Cancer Center oncology clinics were approached for recruitment to the Prostate Cancer Genetic Risk Evaluation of SNPs Study (PROGRESS). Participants completed a demographic and clinical questionnaire and provided a peripheral blood sample. Only patients with confirmed ADT initiation dates were included in this analysis. Germ-line DNA was analyzed for SNP genotyping on a 128-SNP chip using a TaqMan OpenArray GT Kit (Applied Biosystems). The chip included genes critical to hormone signaling, transport, and elimination pathways with minor allele frequencies > 5%. Patients were followed for progression-free survival (PFS) and overall survival (OS) endpoints. Univariable analyses were performed to identify significant associations between SNP genotype, clinical parameters, and PFS and OS outcomes. Results: 107 patients with PCa initiated on ADT enrolled. Demographics included: age (median)–69 yrs, prostate specific antigen (PSA) (median)–28.0 ng/ml, PSA doubling time (median)–4.9 months, biochemical/metastatic–25%/75%, concurrent anti-androgen therapy–44%. No clinical parameters were associated with PFS and OS. Significant SNP associations with PFS and OS are summarized in the Table. Conclusions: Interpatient differences in hormone pathway germ-line SNPs may contribute to variability in clinical outcomes in patients treated with ADT. [Table: see text] [Table: see text]

Abstract
54 Background: Recent trials have highlighted the clinical utility of second-line hormonal therapies for CRPC. KC, an oral inhibitor of CYP3A4 and CYP17, is commonly used in this setting. Germline SNPs in genes critical to hormone synthesis, transport, metabolism, binding sites, and degradation may contribute to variability in outcomes observed in KC treated CRPC pts. Methods: Between 1/07 and 10/08, all PCa pts seen in the Indiana University Simon Cancer Center oncology clinics were approached for recruitment to the Prostate Cancer Genetic Risk Evaluation of SNPs Study (PROGRESS). Participants completed a demographic and clinical questionnaire and provided a peripheral blood sample. Only pts with initiated on KC were included in this analysis. Germline DNA was analyzed for SNP genotyping on a 128-SNP chip using a TaqMan OpenArray GT Kit. The chip included genes critical to hormone signaling, transport, and elimination pathways with minor allele frequencies > 5%. Pts were followed for progression-free survival (PFS) and overall survival (OS) endpoints. Univariable analyses were performed to identify significant associations between SNP genotype, clinical parameters, and PFS and OS outcomes. Results: Between January 2007 and October 2008, 39 pts with CRPC initiated on KC therapy enrolled. Demographics included: age (median) – 70 yrs, prostate specific antigen (PSA) (median) – 13.0 ng/ml, PSA doubling time (median) – 2.9 months, metastatic –85%, ECOG PS 0– 74%. Age < 70 was associated with shorter PFS (p=0.010) and age > 70 was associated with shorter OS (p=0.030). SNPs significantly associated with PFS and OS are summarized in the table. Conclusions: Interpatient differences in hormonal pathway germline SNPs may contribute to variability in clinical outcomes in pts treated with KC.

Abstract
50 Background: We evaluated the cytotoxic effects of combining of suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, with taxanes in human gastric cancer cell lines, and evaluated the pre-treatment difference of gene profile to identify genes that could potentially mediate the cytotoxic response. Methods: Twenty-five gastric cancer cell lines with 22K gene expression data were treated with SAHA and paclitaxel or docetaxel, and the synergistic interaction between the drugs was evaluated in vitro using the combination index (CI) method. We performed significance analysis of microarray (SAM) to identify chemosensitivity-related genes in gastric cancer cell lines that were concomitantly treated with SAHA and taxane. We generated a correlation-matrix between gene expression and CI values to identify genes whose expression correlated with a combined effect of taxanes and SAHA. Results: Taxane and SAHA combination had a synergistic cytotoxic effect against taxane-resistant gastric cancer cells. We selected 49 chemosensitivity-related genes, which were commonly identified in paclitaxel and docetaxel combined with SAHA, via SAM analysis. Among them, nine common genes (SLIT2, REEP2, EFEMP2, CDC42SE1, FSD1, POU1F1, ZNF79, ETNK1, and DOCK5) were extracted from the subsequent correlation-matrix analysis. Conclusions: Taxane and SAHA combination could be efficacious for the treatment of gastric cancer. The genes which were related with the synergistic response to taxane and SAHA could serve as surrogate biomarkers to predict the therapeutic response in gastric cancer patients. We are researching to determine the expression of the nine genes in malignant human gastric cancer tissue and to correlate them with clinical information.
