- Aim: To describe the distribution of enamel-, dentin-, root- and secondary caries within an elderly population in Northern-Norway. Material and methods: A study population (n = 1 173) was divided into age groups: 65-69 (seniors), 70-74 (young elderly), 75-79 (elderly) and 80-94 (old elderly). Seven examiners registered presence, location and severity of caries lesions on x-rays and intra-oral photos. Severity of approximal, occlusal, secondary and root caries was graded (D1-2: into enamel; D3-5: into dentin, root caries)(,) and decayed missing filled surfaces/teeth (DMFS/DMFT) were calculated. T-test, ANOVA and a Bonferroni correction were used. Results: The seniors had more primary caries (DS1-5) compared to the oldest age groups, while the old elderly had significantly more secondary caries than the other groups (p < .05). Of those >= 65 years 13.8% were affected with root caries, 21% among the oldest. About 48% of the old elderly had one or more surfaces with untreated caries lesions into dentin, while for the other groups the number was 35% (p < 0.05). Conclusion: Individuals seem to maintain good oral health up to at least 80 years of age. Those older than 80 years have more root caries needing more intensified caries-controlling measures and a higher prevalence of untreated dentin lesions often in need of operative treatment.

- AZD0837 is an investigational oral anticoagulant which is converted to the active form, ARH067637, a selective direct thrombin inhibitor. The present study, a multicentre, randomised, parallel-group, dose-guiding study, assessed the safety and tolerability of an immediate-release formulation of AZD0837 compared with dose-adjusted warfarin in the prevention of stroke and systemic embolic events in atrial fibrillation (AF) patients. Two hundred fifty AF patients with at least one additional risk factor for stroke were randomised to receive either immediate-release AZD0837 (150mg twice daily [bid] or 350mg bid, blinded treatment) or dose-adjusted warfarin (international normalised ratio 2.0-3.0, open treatment) for three months. The safety and tolerability of 150mg bid AZD0837 appeared to be as good as that of warfarin. Total bleeding events were six with 150mg bid AZD0837, 15 with 350mg bid AZD0837, and eight with warfarin. Alanine aminotransferase elevations (>3xupper limit of normal) were infrequent, without apparent differences between treatment groups. A numerically higher incidence of serious adverse events was observed with 350mg bid AZD0837 compared with 150mg bid, with six of 13 being cardiac related, all with different diagnoses. An increase in mean serum creatinine of approximately 10% was observed in both AZD0837 groups, which returned to baseline after completion of therapy. There were no strokes, transient ischaemic attacks or cerebral haemorrhages with any of the treatments. In conclusion, the safety and tolerability of 150mg bid immediate-release AZD0837 appeared to be as good as that of dose-adjusted warfarin. However, larger studies will be needed to define the safety profile of AZD0837.

- Background: Oxaliplatin in combination with capecitabine prolongs survival in patients with metastatic colorectal cancer (mCRC). Chronomodulation might reduce toxicity and improve efficacy. Patients and methods: A phase II study examining chronomodulated XELOX30 (XELOX30chron): oxaliplatin: 130 mg/m2 on day 1, as a 30-min infusion between 1 and 3 p.m. Capecitabine: total daily dose of 2000 mg/m2, 20% of the dose between 7 and 9 a.m. and 80% of the dose between 6 and 8 p.m. in patients with mCRC resistant to irinotecan. Seventy-one patients were enrolled. Response rate was 18%, median progression-free survival 5.1 months and median overall survival (OS) 10.2 months. Platelet count and performance status were significantly correlated to OS in multivariate analyses. Neurotoxicity grade 2 and 3 was seen in 25% and 2% of patients, respectively, other grade 3 toxic effects were as follows: nausea 6%, vomiting 3%, diarrhoea 12% (3% experienced grade 4) and palmoplantart erytem 9%. Conclusion: XELOX30chron is a convenient second-line regimen with efficacy and safety profile similar to other oxaliplatin schedules. To further investigate chronomodulated XELOX, we have started a Nordic randomised phase II study comparing XELOX30 and XELOX30chron as first-line therapy in patients with mCRC. © The Author 2008.

- Background: We aim to test the hypothesis that high plasma YKL-40 is associated with short progression-free survival (PFS) and overall survival (OS) in patients with metastatic colorectal cancer (mCRC) treated with first-line oxaliplatin and 5-flourouracil with or without cetuximab. Patients and Methods: A total of 566 patients in the NORDIC VII Study were randomized 1:1:1 to arm A (Nordic FLOX), arm B (Nordic FLOX + cetuximab), or arm C (Nordic FLOX + cetuximab for 16 weeks followed by cetuximab alone as maintenance therapy). Pretreatment plasma samples were available from 510 patients. Plasma YKL-40 was determined by ELISA and dichotomized according to the age-corrected 95% YKL-40 level in 3130 healthy subjects. Results: Pretreatment plasma YKL-40 was elevated in 204 patients (40%), and median YKL-40 was higher in patients with mCRC than in healthy subjects (age adjusted, P < 0.001). Patients with elevated YKL-40 had shorter PFS than patients with normal YKL-40 (7.5 vs. 8.2 months; hazard ratio (HR) = 1.27 95% confidence interval (CI) 1.05-1.53 P = 0.013) and shorter OS (16.8 vs. 23.9 months; HR = 1.33, 1.04-1.69, P = 0.024). Multivariate Cox analysis demonstrated that elevated pretreatment YKL-40 was an independent biomarker of short OS (HR = 1.12, 1.01-1.25, P = 0.033). The ratio of the updated plasma YKL-40 (i.e. level after 1, 2, 8 weeks of treatment, and at end of treatment compared to the baseline level) was associated with OS (HR = 1.27, 1.06-1.52, P = 0.011). Conclusions: Plasma YKL-40 is an independent prognostic biomarker in patients with mCRC treated with first-line oxaliplatin-based therapy alone or combined with cetuximab.

- It is now widely accepted that therapeutic antibodies targeting epidermal growth factor receptor (EGFR) can have efficacy in KRAS wild-type advanced colorectal cancer (CRC) patients. What remains to be ascertained is whether a subgroup of KRAS-mutated CRC patients might not also derive benefit from EGFR inhibitors. Metalloproteinase inhibitor 1 (TIMP-1) is a pleiotropic factor predictive of survival outcome of CRC patients. Levels of TIMP-1 were measured in pre-treatment plasma samples (n = 426) of metastatic CRC patients randomized to Nordic FLOX (5-fluorouracil and oxaliplatin) +/- cetuximab (NORDIC VII study). Multivariate analysis demonstrated a significant interaction between plasma TIMP-1 protein levels, KRAS status and treatment with patients bearing KRAS mutated tumors and high TIMP-1 plasma level (> 3rd quartile) showing a significantly longer overall survival if treated with cetuximab (HR, 0.48; 95% CI, 0.25 to 0.93). To gain mechanistic insights into this association we analyzed a set of five different CRC cell lines. We show here that EGFR signaling induces TIMP-1 expression in CRC cells, and that TIMP-1 promotes a more aggressive behavior, specifically in KRAS mutated cells. The two sets of data, clinical and in vitro, are complementary and support each other, lending strength to our contention that TIMP-1 plasma levels can identify a subset of patients with KRAS-mutated metastatic CRC that will have benefit from EGFR-inhibition therapy.

- Background According to previous studies, older patients frequently have serum concentrations of antidepressant medication above the recommended reference range. Objective The aim of this study was to investigate whether prescribed doses of antidepressants and the proportion of individuals with serum concentrations above the recommended reference range in older individuals (>= 65 years) have changed over a 10-year period in Norway. Methods Serum concentration measurements and prescribed daily doses of antidepressants in 2007 and 2017 were extracted from a therapeutic drug monitoring (TDM) database at the Center for Psychopharmacology, Diakonhjemmet Hospital, Oslo, Norway. The database contains routine follow-up serum concentration measurements of psychotropic drugs for patients from all parts of the country. For citalopram, escitalopram, sertraline, mirtazapine and venlafaxine, the differences between 2007 and 2017 in mean prescribed doses and the proportion of patients with at least one serum concentration above the reference range, according to the Arbeitsgemeinschaft fur Neuropsychopharmakologie und Pharmakopsychiatrie (AGNP) guidelines, were compared. For the proportion of patients with serum concentrations above the recommended reference range, differences between individuals aged 65-79 and >= 80 years were also examined. Results The analyses of prescribed doses included 806 patients from 2007 and 1932 patients from 2017, with 972 and 2441 TDM samples, respectively. Between 2007 and 2017, modest reductions in prescribed daily doses were observed for citalopram (20 vs. 17 mg/day) and escitalopram (11 vs. 10 mg/day), but the proportion of patients with serum concentrations above the recommended reference range was unchanged for both drugs, i.e. 11.5% vs. 12.4% for citalopram and 3.6% vs. 2.9% for escitalopram. For mirtazapine and venlafaxine, prescribed doses were reduced from 28 to 25 mg/day and 150 to 125 mg/day, respectively. A significant reduction in the proportion of individuals with serum concentrations above the recommended reference range was observed for mirtazapine (27.1% vs. 11.5%) and for individuals aged >= 80 years using venlafaxine (60.0% vs. 30.0%). For sertraline, no differences in prescribed doses or serum concentrations above the recommended reference range were observed. Conclusions Over a 10-year period, prescribed doses of antidepressants have been slightly reduced in older Norwegian patients, but a considerable proportion is still exposed to high serum concentrations of antidepressants.
