There is little reliable evidence that electronic cigarettes are effective for long-term smoking cessation, according to a new analysis of the currently available research which was presented at the 2015 American Thoracic Society International Conference.
Certain flavorings used in electronic cigarette liquid may alter important cellular functions in lung tissue, according to new research presented at the 2015 American Thoracic Society International Conference. These changes in cell viability, cell proliferation, and calcium signaling are flavor-dependent. Coupling these results with chemicals identified in each flavor could prove useful in identifying flavors or chemical constituents that produce adverse effects in users.
Unlike standard cigarettes, the components of electronic cigarettes are not regulated and standardized, thus they vary widely between products. The characteristics of these e-cigarette elements, including their delivery systems, combustion apparatuses, and the composition of the nicotine solutions they contain may affect the levels of potentially hazardous substances in the vapor they produce, according to a new study presented at the 2015 American Thoracic Society International Conference.

A diabetes drug may have benefits beyond lower blood sugar in patients with HIV. New research from Washington University School of Medicine in St. Louis suggests the drug may prevent cardiovascular problems because it works to reduce inflammation that is linked to heart disease and stroke in these patients. The drug both improved metabolism and reduced inflammation in HIV-positive adults on antiretroviral therapy.
A study, published online ahead of print May 14 in the American Journal of Transplantation, revealed that there are nearly 400 HIV-positive potential organ donors who could be sources of donated organs annually for HIV-positive patients waiting for organ donations.
Secondhand exposure to cannabis smoke under “extreme conditions,” such as an unventilated room or enclosed vehicle, can cause nonsmokers to feel the effects of the drug, have minor problems with memory and coordination, and in some cases test positive for the drug in a urinalysis. Those are the findings of a Johns Hopkins University School of Medicine study, reported online this month in the journal Drug and Alcohol Dependence.
Four different financial incentive programs, each worth roughly $800 over six months, all help more smokers kick the habit than providing free access to behavioral counseling and nicotine replacement therapy. Further, the way in which equally-sized payouts are structured influences their effectiveness. The findings are the result of a year-long randomized trial among CVS Caremark (now CVS Health) employees that was conducted by researchers at the University of Pennsylvania.
Smokers who are able to quit might actually be hard-wired for success, according to a study from Duke Medicine. The study, published in Neuropsychopharmacology, showed greater connectivity among certain brain regions in people who successfully quit smoking compared to those who tried and failed.

Over nearly 15 years spent studying ticks, Indiana University's Keith Clay has found southern Indiana to be an oasis free from Lyme disease, the condition most associated with these arachnids that are the second most common parasitic disease vector on Earth. He has also seen signs that this low-risk environment is changing, both in Indiana and in other regions of the U.S.
Scientists have identified a protein on the surface of human red blood cells that serves as an essential entry point for invasion by the malaria parasite. This discovery opens up a promising new avenue for the development of therapies to treat and prevent malaria.
New research led by NCAR and CDC has identified correlations between weather conditions and the occurrence of West Nile virus disease in the United States, raising the possibility of being able to better predict outbreaks.
A University of North Carolina at Chapel Hill analysis published in the journal Tobacco Control synthesized the results of 37 different experiments comparing picture-based and text warnings, finding that picture-based warnings were more effective than text warnings on 20 of 25 different outcome measures.
A 12-week dose of an investigational three-drug hepatitis C combination cured the virus in 93 percent of patients with liver cirrhosis who hadn’t previously been treated, according to a study in the May 5, 2015, issue of The Journal of the American Medical Association.
Researchers at NYU Langone Medical Center have identified an important role for calcium signaling in immune responses to chronic infection resulting from Mycobacterium tuberculosis, the bacterium causing tuberculosis (TB).
Scientists have uncovered a potential mode of parasite drug resistance in malaria infection, opening new opportunities for the design of anti-malarial drugs.
As the realities of legalized marijuana take hold in four states and the District of Columbia, legislators and regulators could learn a lot from the successes – and failures – of the tobacco and alcohol industries in keeping their harmful products out of the hands of children and adolescents.
Writing in the April 30 online issue of the Journal of Steroid Biochemistry and Molecular Biology, researchers at University of California San Diego School of Medicine report pancreatic cancer rates are highest in countries with the least amount of sunlight. Low sunlight levels were due to a combination of heavy cloud cover and high latitude.
