"Aspirin Use and Risk of Colorectal Cancer According to BRAF Mutation Status" 
JAMA Jun 26
http://jama.jamanetwork.com/article.aspx?articleid=1700495 
"Conclusions and Relevance  Regular aspirin use was associated with lower risk of BRAF–wild-type colorectal cancer but not with BRAF-mutated cancer risk. These findings suggest that BRAF-mutant colon tumor cells may be less sensitive to the effect of aspirin. Given the modest absolute risk difference, further investigations are necessary to determine clinical implications of our findings."

"Recommendation: The USPSTF recommends screening for HCV infection in persons at high risk for infection. The USPSTF also recommends offering 1-time screening for HCV infection to adults born between 1945 and 1965. (B recommendation)"

"Changes in Plaque Lipid Content After Short-Term Intensive Versus Standard Statin Therapy"  
JACC July 2013

"Conclusions  Short-term intensive statin therapy may reduce lipid content in obstructive lesions. These hypothesis-generating findings warrant confirmation in larger studies with longer follow-up."

Circ May/Jun 2013
http://circ.ahajournals.org/content/127/25/2494.abstract
"Conclusions—This trial provides data supporting an early CCTA strategy as an attractive option in women presenting to the ED with symptoms suggestive of acute coronary syndrome. The findings may be explained by lower CAD prevalence and severity in women than men."

"Effect of thrombolysis with alteplase within 6 h of acute ischaemic stroke on long-term outcomes (the third International Stroke Trial [IST-3]): 18-month follow-up of a randomised controlled trial"
Lancet Jun 21
http://www.lancet.com/journals/laneur/article/PIIS1474-4422(13)70130-3/fulltext 
"Interpretation

IST-3 provides evidence that thrombolysis with intravenous alteplase for acute ischaemic stroke does not affect survival, but does lead to statistically significant, clinically relevant improvements in functional outcome and health-related quality of life that are sustained for at least 18 months."

"Anaemia, prenatal iron use, and risk of adverse pregnancy outcomes: systematic review and meta-analysis" 
BMJ Jun 2013
http://www.bmj.com/content/346/bmj.f3443
"Conclusions Daily prenatal use of iron substantially improved birth weight in a linear dose-response fashion, probably leading to a reduction in risk of low birth weight. An improvement in prenatal mean haemoglobin concentration linearly increased birth weight."
