Abstract
This paper provides a pragmatic approach to analysing qualitative data, using actual data from a qualitative dental public health study for demonstration purposes. The paper also critically explores how computers can be used to facilitate this process, the debate about the verification (validation) of qualitative analyses and how to write up and present qualitative research studies.

Abstract
BACKGROUND In subjects with a high prevalence of metabolic risk abnormalities, the preferred replacement for saturated fat is unresolved. OBJECTIVE The objective was to study whether carbohydrate or monounsaturated fat is a preferred replacement for saturated fat. DESIGN Fifty-two men and 33 women, selected to have any combination of HDL cholesterol < or = 30th percentile, triacylglycerol > or = 70th percentile, or insulin > or = 70th percentile, were enrolled in a 3-period, 7-wk randomized crossover study. The subjects consumed an average American diet (AAD; 36% of energy from fat) and 2 additional diets in which 7% of energy from saturated fat was replaced with either carbohydrate (CHO diet) or monounsaturated fatty acids (MUFA diet). RESULTS Relative to the AAD, LDL cholesterol was lower with both the CHO (-7.0%) and MUFA (-6.3%) diets, whereas the difference in HDL cholesterol was smaller during the MUFA diet (-4.3%) than during the CHO diet (-7.2%). Plasma triacylglycerols tended to be lower with the MUFA diet, but were significantly higher with the CHO diet. Although dietary lipid responses varied on the basis of baseline lipid profiles, the response to diet did not differ between subjects with or without the metabolic syndrome or with or without insulin resistance. Postprandial triacylglycerol concentrations did not differ significantly between the diets. Lipoprotein(a) concentrations increased with both the CHO (20%) and MUFA (11%) diets relative to the AAD. CONCLUSIONS In the study population, who were at increased risk of coronary artery disease, MUFA provided a greater reduction in risk as a replacement for saturated fat than did carbohydrate.

Abstract
The aim of this investigation was to determine the effect of growth factor treatment on ovine meniscal chondrocyte (OMC) proliferation in vitro and on the production of matrix proteins by OMCs grown within a polyglycolic acid (PGA) scaffold. Analysis of 72-h monolayer cultures using the mean transit time (MTT) assay revealed a greater increase in OMC numbers in the presence of platelet-derived growth factor (PDGF)-AB, PDGF-BB, insulin-like growth factor (IGF)-I, transforming growth factor-beta1 (TGF-beta1) and basic fibroblast growth factor (bFGF) than in untreated controls. In contrast, IGF-II and bone morphogenetic protein-2 had no effect on OMC proliferation at the concentrations tested. The growth factors that elicited the greatest proliferative response (PDGF-AB, PDGF-BB, TGF-beta1, and IGF-I) were subsequently tested for their ability to enhance OMC proliferation and differentiation within PGA scaffolds. Biochemical analysis revealed less glycosaminoglycan (GAG) production in the presence of all growth factors tested compared to untreated control samples. In contrast, all of the growth factors increased collagen type I production by OMCs within the scaffolds at day 20, and all except PDGF-BB resulted in an increase at day 39, when compared to appropriate control samples. With the exception of IGF-I, none of the growth factors tested had any significant effect on collagen type II production. Histological staining of sections from OMC-PGA scaffolds did not reveal any difference in GAG or collagen production between the treatment groups. However, immunohistochemical analysis demonstrated an increase in collagen type I expression and a decrease in collagen type II at day 39 in all growth factortreated constructs, concomitant with a high infiltration of cells. This suggests that PDGF-AB, PDGF-BB, TGF-beta1, and IGF-1 may be useful in future tissue engineering studies for promoting meniscal cell proliferation and differentiation within scaffolds.

Abstract
AIM To assess the impact of a community pharmacy diabetes service model on patient outcomes in Type 2 diabetes. METHODS The study utilized a multisite, control vs. intervention, repeated-measures design within four states in Australia. Fifty-six community pharmacies, 28 intervention and 28 control, were randomly selected from a representative sample of urban and rural areas. Intervention pharmacies delivered a diabetes service to patients with Type 2 diabetes, which comprised an ongoing cycle of assessment, management and review, provided at regular intervals over 6 months in the pharmacy. These services included support for self monitoring of blood glucose, education, adherence support, and reminders of checks for diabetes complications. Control pharmacists assessed patients at 0 and 6 months and delivered no intervention. RESULTS A total of 289 subjects (149 intervention and 140 control) completed the study. For the intervention subjects, the mean blood glucose level decreased over the 6-month study from 9.4 to 8.5 mmol/l (P < 0.01). Furthermore, significantly greater improvements in glycaemic control were seen in the intervention group compared with the control: the mean reduction in HbA(1c) in the intervention group was -0.97% (95% CI: -0.8, -1.14) compared with -0.27% (95% CI: -0.15, -0.39) in the control group. Improvements were also seen in blood pressure control and quality of life in the intervention group. CONCLUSION A pharmacy diabetes service model resulted in significant improvements in clinical and humanistic outcomes. Thus, community pharmacists can contribute significantly to improving care and health outcomes for patients with Type 2 diabetes. Future research should focus on clarifying the most effective elements of the service model.

Abstract
Compound A-837093, a non-nucleoside HCV RNA-dependent RNA polymerase inhibitor, displayed nanomolar potencies against HCV genotypes 1a and 1b replicons. It also exhibited an excellent metabolic profile and achieved high plasma and liver concentrations in animals. In order to characterize the development of resistance to this anti-HCV agent, HCV subgenomic 1b strain N replicon cells were cultured in the presence of A-837093 with G418. Mutations S368A, Y448H, G554D, Y555C, and D559G in the NS5B polymerase gene were identified that led to substantial decreases in the susceptibilities of 1b genotype replicons to the inhibitor A-837093. However, the resistant mutants remained susceptible to HCV protease inhibitor BILN-2061 and alpha interferon as well as to a different class of non-nucleoside HCV polymerase inhibitor. In addition, each single resistant mutation identified significantly reduced the replication capacity of mutant compared to wild-type replicon. These findings provide a strategic guide for the future development of non-nucleoside inhibitors of HCV NS5B polymerase.

Abstract
OBJECTIVE To compare the efficacy and cost-effectiveness of two methods of screening for undiagnosed type 2 diabetes in Australian community pharmacy. METHODS A random sample of 30 pharmacies were allocated into two groups: (i) tick test only (TTO); or (ii) sequential screening (SS) method. Both methods used the same initial risk assessment for type 2 diabetes. Subjects with one or more risk factors in the TTO group were offered a referral to their general practitioner (GP). Under the SS method, patients with risk factors were offered a capillary blood glucose test and those identified as being at risk referred to a GP. The effectiveness and cost-effectiveness of these approaches was assessed. RESULTS A total of 1286 people were screened over a period of 3 months. The rate of diagnosis of diabetes was significantly higher for SS compared with the TTO method (1.7% versus 0.2%; p=0.008). The SS method resulted in fewer referrals to the GP and a higher uptake of referrals than the TTO method and so was the more cost-effective screening method. CONCLUSIONS SS is the superior method from a cost and efficacy perspective. It should be considered as the preferred option for screening by community based pharmacists in Australia.

Abstract
A novel series of pyrrolidine-constrained phenethylamines were developed as dipeptidyl peptidase IV (DPP4) inhibitors for the treatment of type 2 diabetes. The cyclohexene ring of lead-like screening hit 5 was replaced with a pyrrolidine to enable parallel chemistry, and protein co-crystal structural data guided the optimization of N-substituents. Employing this strategy, a >400x improvement in potency over the initial hit was realized in rapid fashion. Optimized compounds are potent and selective inhibitors with excellent pharmacokinetic profiles. Compound 30 was efficacious in vivo, lowering blood glucose in ZDF rats that were allowed to feed freely on a mixed meal.

Abstract
Elimination of syphilis within Aboriginal communities is one of the stated goals of the NSW Sexually Transmissible Infections Strategy 2006-2009. In 2007, a project was undertaken to inform strategy development to achieve the goal of elimination of infectious syphilis in Aboriginal communities.
Australian and international literature on elimination strategies for syphilis, STIs and other diseases was reviewed. Surveillance data were accessed through the National Notifiable Diseases Surveillance System and NSW Notifiable Disease Database and analysed to describe the current burden of disease. Key informants were consulted for advice on elimination strategies for infectious syphilis for Aboriginal people and possible barriers to the goal.
Infectious syphilis notifications for Aboriginal people have decreased significantly from 64% of all infectious syphilis cases in 1995 to 3% in 2006. For the rest of the population notifications have increased. Changes in male to female ratios and an increase in metropolitan notifications have been noted in recent years. Improvements in recording of Aboriginality information for infectious syphilis in NSW have allowed greater confidence in interpreting these trends. The role of accurate and complete surveillance information will play an important role in planning and directing the implementation of interventions to achieve the goal of syphilis elimination for Aboriginal people in NSW.
Challenges to the goal of elimination and the feasibility of a disease elimination strategy specific for Aboriginal people include issues of access to services for testing, diagnosis and treatment; cross-border mobility of Aboriginal people; prevalence of syphilis in the wider community; and continued access to accurate information. Lessons learned from international and Australian elimination strategies; burden of disease information; definition of elimination and target rates; challenges and strategies for achieving the goal of syphilis elimination and will be discussed.

Abstract
17502 Background: CHIR-258 is an orally active small molecule receptor tyrosine kinase (RTK) inhibitor which has potent activity against multiple RTKs involved in tumor growth and angiogenesis (IC50 ≤13 nM for FGFR, VEGFR, PDGFR, C-KIT, and FLT3). Approximately 15% of newly diagnosed MM patients harbor a t(4;14) translocation, which results in ectopic expression of FGFR3 and MMSET and is associated with poor treatment outcome [0]and reduced survival. CHIR-258 inhibits proliferation and induces apoptosis in FGFR3-expressing MM tumor xenografts as well as FGFR3-expressing primary MM cells (Trudel et al, Blood 2005). CHIR-258 was synergistic with dexamethasone (dex) in vitro. Methods: CHIR-258 was administered once daily in a dose-escalating phase 1 study to patients with relapsed/refractory MM. Drug tolerability and safety, pharmacokinetics (PK) and pharmacodynamics (PD) were assessed. Results: as of December 2005, 9 total pts have been treated (50, 100, and 200mg qd cohorts) [6M, 3F; median age: 58 (range: 44–68), median of 3 prior therapies(range:1–7)]. Prior tx: 9/9 pts-thalidomide; 8/9 -Velcade; 8/9-transplant; 8/9- had progressed through dex. 4 of 9 pts treated were FGFR3+ and 4 pts remain on study (3 are FGFR3+). No CR or PR have been observed; stable disease has been noted. CHIR-258 has been generally well tolerated, and most drug related AEs were CTC grade 1 or 2, including: headache, dysgeusia, fatigue and anorexia. No neuropathy. One DLT has been observed to date: neutropenia (200mg cohort). Five pts had dex added to CHIR-258 of which 3 are ongoing (all FGFR3+). FGFR3+ pts receiving dex and CHIR-258 have a greater decline in urine and serum paraproteins (pp) vs CHIR-258 alone. Plasma exposure and Cmax increased proportionally across the doses. Conclusions: CHIR-258 is a novel inhibitor of RTKs involved in MM growth and proliferation. FGFR3+ pts have a more marked reduction in pp than FGFR3- pts. CHIR-258 has generally been well tolerated and further accrual continues. [Table: see text]

Abstract
A series of (5-substituted pyrrolidinyl-2-carbonyl)-2-cyanopyrrolidine (C5-Pro-Pro) analogues was discovered as dipeptidyl peptidase IV (DPPIV) inhibitors as a potential treatment of diabetes and obesity. X-ray crystallography data show that these inhibitors bind to the catalytic site of DPPIV with the cyano group forming a covalent bond with the serine residue of DPPIV. The C5-substituents make various interactions with the enzyme and affect potency, chemical stability, selectivity, and PK properties of the inhibitors. Optimized analogues are extremely potent with subnanomolar K(i)'s, are chemically stable, show very little potency decrease in the presence of plasma, and exhibit more than 1,000-fold selectivity against related peptidases. The best compounds also possess good PK and are efficacious in lowering blood glucose in an oral glucose tolerance test in ZDF rats.
