Samples profiled in FANTOM5 (credit: Alistair R. R. Forrest et al./Nature)
A large international consortium of researchers has produced the first comprehensive, detailed map of the way genes work across the major cells and tissues of the human body. The findings describe the complex networks that govern gene activity, and the new information could play a crucial role in identifying the genes involved with disease.
“Now, for the first time, we are able to pinpoint the regions of the genome that can be active in a disease and in normal activity, whether it’s in a brain cell, the skin, in blood stem cells or in hair follicles,” said Winston Hide, associate professor of bioinformatics and computational biology at Harvard School of Public Health (HSPH) and one of the core authors of the main paper in Nature.
“This is a major advance that will greatly increase our ability to understand the causes of disease across the body.”
The research is outlined in a series of papers published March 27, 2014, two in the journal Nature and 16 in other scholarly journals. The work is the result of years of concerted effort among 250 experts from more than 20 countries as part of FANTOM 5 (Functional Annotation of the Mammalian Genome). The FANTOM project, led by the Japanese institution RIKEN, is aimed at building a complete library of human genes.

E-Cigarettes

Journal Scan Summary

Title:A Longitudinal Analysis of Electronic Cigarette Use and Smoking Cessation
Date Posted:  March 24, 2014
Authors:Grana RA, Popova L, Ling PM.
Citation:JAMA Intern Med 2014;Mar 24:[Epub ahead of print].

Study Question:

Do electronic cigarettes (e-cigarettes) improve smoking cessation rates compared to other methods or placebo?

Methods:

This research letter describes data on e-cigarette use in association with quit rates. Participants from the Knowledge Networks who completed a baseline survey in November 2011 and were self-identified current smokers were included in this analysis. Follow-up was conducted through November 2012. A total of 1,549 participants completed the survey in 2011, of which 1,189 were current smokers; 81.3% completed the follow-up survey. An additional 240 provided nonsensical data and were excluded. Baseline e-cigarette (in the prior 30 days) use was measured with the yes or no question. Cigarettes used per day (continuous variable), time to first cigarette
Results:
A total of 949 participants were included in this analysis. Women, younger adults, and individuals with less education were more likely to report using e-cigarettes. At baseline, a greater proportion of e-cigarette users reported smoking their first cigarette
Conclusions:The investigators concluded that e-cigarette use by smokers was not followed by greater rates of quitting or by reduction in cigarette consumption 1 year later. Regulations should prohibit advertising claiming or suggesting that e-cigarettes are effective smoking cessation devices until claims are supported by scientific evidence.

Perspective:

These data suggest that e-cigarette use is not associated with higher quit rates. However, given the small number of e-cigarette users and use of self-reported data on smoking cessation, further study is warranted.
