Efficacy and safety of colchicine for the treatment of myopericarditis

Objective Clinical trials have evaluated the efficacy and safety of colchicine only in simple pericarditis, excluding cases of concomitant myocarditis. The aim of this paper is to evaluate the efficacy and safety of colchicine for the treatment of the first attack of acute pericarditis with concomitant myocardial involvement. Methods Double-centre retrospective cohort study analysing consecutive patients admitted for first attack of pericarditis with myocarditis and treated with or without colchicine. The primary efficacy end point was the time to the first recurrence. Propensity score matching was used to generate two groups of patients with similar baseline characteristics. Colchicine-associated side effects were analysed as safety end-point. Results A total of 175 patients (mean age 46.2±20.1 years, 25.1% females, 88.6% with idiopathic/viral aetiology) were included. Seventy-nine (45.1%) patients were treated with colchicine. After a median follow-up of 25.3 (IQR 8.3-45.6) months, 58 (33.1%) patients had recurrences. The propensity score generated two groups of 73 patients with similar baseline characteristics but the use of colchicine. Patients treated with colchicine had a lower incidence of recurrences (respectively, 19.2% vs 43.8%; p=0.001) and a longer event-free survival (p=0.005). In multivariable analysis, women (HR 1.97, 95% CI 1.04 to 3.73; p=0.037) and corticosteroid use (HR 2.27, 95% CI 1.15 to 4.47; p=0.018) were independent risk factors for recurrences. Colchicine-associated side effects were mild and occurred in 3 (1.7%) patients. Conclusion In patients with first attack of pericarditis associated with myocardial involvement, colchicine was safe and efficacious for the reduction of recurrences

Genetics and genetic counseling: Practices and opinions of primary care physicians in Turkey

PURPOSE: The purpose of this study was to assess the educational needs of physicians relating to genetics and genetic counseling in the Denizli region of Turkey. METHODS: Data were collected by questionnaire about physicians' approaches to genetics and genetic counseling. RESULTS: A total of 60 (60.0%) of 100 physicians working in Denizli province returned a questionnaire. Physicians described "their most knowledgeable subjects" in basic genetic information as chromosome abnormalities (41.8%), in genetic disorders as xeroderma pigmentosum (80.0%), and in genetic counseling as directing the parents of and couples with a risk for having a child affected by a genetic disease to an expert or a genetic counseling center (94.8%). Only 20.7% knew the ethical regulations and techniques related to genetic counseling. Physicians thought that they did not have sufficient knowledge about genetics or genetic counseling, and 83.9% would like to attend an educational course. CONCLUSIONS: As a result of this study, a genetics course is planned for physicians so they can actively participate in the prevention and early diagnosis of genetic diseases. ©2007The American College of Medical Genetics

Angiotensin II Requires Zinc and Downregulation of the Zinc Transporters ZnT3 and ZnT10 to Induce Senescence of Vascular Smooth Muscle Cells

Senescence, a hallmark of mammalian aging, is associated with the onset and progression of cardiovascular disease. Angiotensin II (Ang II) signaling and zinc homeostasis dysfunction are increased with age and are linked to cardiovascular disease, but the relationship among these processes has not been investigated. We used a model of cellular senescence induced by Ang II in vascular smooth muscle cells (VSMCs) to explore the role of zinc in vascular dysfunction. We found that Ang II-induced senescence is a zinc-dependent pathway mediated by the downregulation of the zinc transporters ZnT3 and ZnT10, which work to reduce cytosolic zinc. Zinc mimics Ang II by increasing reactive oxygen species (ROS), activating NADPH oxidase activity and Akt, and by downregulating ZnT3 and ZnT10 and inducing senescence. Zinc increases Ang II-induced senescence, while the zinc chelator TPEN, as well as overexpression of ZnT3 or ZnT10, decreases ROS and prevents senescence. Using HEK293 cells, we found that ZnT10 localizes in recycling endosomes and transports zinc into vesicles to prevent zinc toxicity. Zinc and ZnT3/ZnT10 downregulation induces senescence by decreasing the expression of catalase. Consistently, ZnT3 and ZnT10 downregulation by siRNA increases ROS while downregulation of catalase by siRNA induces senescence. Zinc, siZnT3 and siZnT10 downregulate catalase by a post-transcriptional mechanism mediated by decreased phosphorylation of ERK1/2. These data demonstrate that zinc homeostasis dysfunction by decreased expression of ZnT3 or ZnT10 promotes senescence and that Ang II-induced senescence is a zinc and ROS-dependent process. Our studies suggest that zinc might also affect other ROS-dependent processes induced by Ang II, such as hypertrophy and migration of smooth muscle cells

Shoe-Leather Costs in the Euro Area and the Foreign Demand for Euro Banknotes

We estimate the shoe-leather costs of inflation in the euro area using monetary data adjusted for holdings of euro banknotes abroad. While we find evidence of marginally negative shoe-leather costs for very low levels of the nominal interest rate, our estimates suggest that the shoe-leather costs are non-negligible even for relatively moderate levels of anticipated inflation. We conclude that, despite the increased circulation of euro banknotes abroad, in the euro area the inflation tax is still predominantly borne by domestic agents, with transfers of resources from abroad remaining small

Bank Risk and Monetary Policy

We find evidence of a bank lending channel for the euro area operating via bank risk. Financial innovation and the new ways to transfer credit risk have tended to diminish the informational content of standard bank balance-sheet indicators. We show that bank risk conditions, as perceived by financial market investors, need to be considered, together with the other indicators (i.e. size, liquidity and capitalization), traditionally used in the bank lending channel literature to assess a bank’s ability and willingness to supply new loans. Using a large sample of European banks, we find that banks characterized by lower expected default frequency are able to offer a larger amount of credit and to better insulate their loan supply from monetary policy changes

Supplementary documentation: Bayesian inference in a structural model of family home prices

We present a representative consumer model of housing consumption and analyse the conseqences of the no arbitrage condition for housing prices. Excess returns of housing over the riskless rate admit an explanation based on weakly separable preferences and collateral constraints. A Bayesian vector autoregression model shows that the logarithmic rent/price ratio is a persistent variable and the dynamics of housing prices over the business cycle is mainly determined by financial factors.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.
