Giving up smoking after a heart attack has been clearly associated with improvements in long-term patient survival, but how soon after myocardial infarction does smoking cessation begin to have positive effects? A study published in the current issue of The American Journal of Medicine indicates in-hospital cessation counseling following heart attacks is associated with better short-term survival. Counseling smokers to quit reduced their chances of dying in the first 30 days, 60 days and up to 1 year after their attacks.
The study, conducted by investigators at the University of Alabama at Birmingham and the Deep South Center on Effectiveness at the Birmingham VA Medical Center, Birmingham, Alabama, analyzed the patient records of over 16,000 smokers, finding that 41% had received counseling. Compared with those not counseled, those who had received inpatient counseling had lower 30-day (2.0% vs. 3.0%), 60-day (3.7% vs. 5.6%), and 2-year mortality (25.0% vs. 30%). Even after adjusting for other factors such as demographic characteristics and comorbid conditions, those counseled were still less likely to die in the first year.
Writing in the article, Thomas K. Houston, MD, MPH, explains, "The positive association of smoking cessation counseling with survival that we observed provides evidence for an association suggested, but not directly demonstrated, by previous reports on the impact of counseling on cessation and the impact of cessation on mortality. In addition, the association of counseling with mortality was seen early, within 30 days. A major conclusion of the U.S. Surgeon Generals report Health Effects of Smoking Cessation is that quitting smoking has an immediate effect on mortality. However, the immediate effect referred to is the reduction in mortality over the first year of cessation. Our research suggests an even more immediate positive association within 30 days of quitting after a cardiac event. Because we observed much of the overall difference in mortality by smoking cessation counseling early, an alternative strategy for risk reduction in those patients unwilling to quit for good would be to recommend, at a minimum, to maintain the in-hospital mandated smoking deprivation for a brief period after discharge."

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
