P573_R588dup, p.G592_K593dup) and one novel mutation in PDGFRA (p.D842_N848delinsVDV), thus contributing to widening the spectrum of known mutations in GIST tumors and confirming the most frequently altered regions underlying GIST development.
Among the 64 KIT- and PDGFRA-positive sporadic patients in our series, no BRAF or KRAS mutations were identified, suggesting that co-occurrence of these mutations is likely to be rare in the northwestern Italian population
and not a frequent cause of primary resistance to imatinib in KIT-positive GIST patients.”
“Objective: This study examined the possible age- and gender-related differences in the use of secondary medical prevention following primary vascular reconstruction in a population-based long-term follow-up study.
Methods: Using information from nationwide Danish registers, we identified all patients undergoing primary vascular reconstruction in-between selleck chemical 1996 and 2006 (n = 20,761). Data were obtained on all filled prescriptions 6 months and 3, 5 and 10 years after primary vascular reconstruction. Comparisons were made across age and gender groups, using men 40-60 years old as a reference.
Results: Compared
to current guidelines the overall use of secondary medical prevention was moderate to low (e.g., lipid-lowering drugs 49.5%, angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists (ACE/ATII) 43.4%, combination of lipid-lowering drugs and anti-platelet therapy and any anti-hypertensive therapy 44.7%). A decline was observed between LY3023414 molecular weight LY333531 hydrochloride 6 months and 3 years after surgery. Patients >80 years old were less likely to be prescribed lipid-lowering drugs and combination therapy (e.g.: adjusted risk ratio (RR) 5 years after surgery for men and women 0.63 (95% confidence interval (CI): 0.39-1.02) and 0.48 (95%CI: 0.31-0.75), respectively, whereas smaller and statistical nonsignificant gender-related differences were observed. The age- and gender-related differences appeared eliminated or substantially reduced in the latest part of the
study period (2001-2007).
Conclusion: We found moderate to low use of secondary medical prevention in Denmark compared with recommendations from clinical guidelines. However, the use has increased in recent years and age- and gender-related differences have been reduced or even eliminated. (C) 2011 European Society for Vascular Surgery. Published by Elsevier Ltd.

“Introduction: Electrocardiogram (ECG) signals in safety pharmacology studies are generally collected via subcutaneous or epicardial leads. Subcutaneous placement is an easier procedure, but signals often contain artifacts. Epicardial leads offer improved quality but require additional surgical expertise. Signal quality and tolerability of intravenous (IV)/diaphragmatic ECG leads were investigated as a less invasive alternative to the epicardial ECG lead approach for cardiovascular assessment in dogs.
