    Very disturbing trend.  Study finds that opioid addicted infants are on a dramatic risk in the US.  This study looked at Neionatal abstinence syndrome from 2000 to 2009.  This follows the significant increase in maternal opioid prescription use.  We physicians must do better.  Patients must demand better.  This study just focused on hospital costs directly associated with the Neonatal period.  No cost estimates are evaluated for long-term care.

    Higher base-line Testosterone levels associated with longer overall survival in men with prostate cancer.  The comparison was 32.7 months with higher T levels versus 22.4 months with lower T levels.  Anemia was also a poor prognostic variable.  Whether exogenous Testosterone therapy will change this is still unclear, but the authors suggest that this should play a role in whether to use salvage hormone therapy.

    No significant statistical significance was found with vitamin D therapy and insulin sensitivity.  However, improved outcomes were found in 2 hour insulin and 2 hour glucose levels after a 75 gram OGTT.

    Another review study.  Low Testosterone is associated with increased CVD in men.  However, some studies have suggested an increase in CVD with men using exogenous Testosterone therapy.  Is Testosterone the cause of CVD in men?  Likely, low T is a

    Review of recent articles suggest increased risk of cardiovascular disease in men. The issue at hand is the cause is not being treated and thus the Testosterone is fuel on the metabolic fire and the doping dose that most men receive.

    Viagra associated with a 84% increased risk of melanoma.  The key word here is associated.  No cause and effect relationship is seen.  Anytime use was also associated with increased risk.  This study did not look at the other phopsphodiesterase 5 inhibitors, though the logic is there risk may be higher as they are longer acting.

    This is the public announcement of a article yet to be published.  The study, yet unread, points to increase damage to brain health in those caucasian men with oxidative stress.  This was not found in mexican-Americans.  Until I read this study, that is all I will say here.

    A large body of evidence exists to associate low vitamin D with cardiovascular disease.  However, this review finds no causal relationship.  Is vitamin D an indicator of poor health?  Or is it the cause of poor health.  Yet to be determined.  Is vitamin D safe? Yes.

    meta-analysis found no high level of evidence to support Huperzine A in the treatment of vascular dementia.  The conclusion sounds scientifically sound, but when you look at the studies included: this is a meta-analysis of 1 of Huperzine A and vascular dementia.  This one study was of 14 participants only and they found improvement in daily functioning.   There are a lot of animal studies that point out benefits of huperzine A and even the mechanisms of action,  but human studies are lacking.  That is a better conclusion.
