Circulating Inflammatory Cytokine Expression in Men With Prostate Cancer Undergoing And... - 0 views

  •  
    this study found no increase in inflammatory cytokines in those men on androgen deprivation therapy for prostate cancer.  The question, is they evaluated testosterone in the serum, so did they really see a decrease in androgens or just a decrease in the transport of androgens.  Saliva would have detected a true androgen deficient state.

Early onset of hyperuricaemia and gout following treatment for female to male gender re... - 0 views

  •  
    sex hormones play a role in the gout.  It appears that testosterone therapy increases uric acid levels and estradiol decreases uric acid levels.  Though, I question this based on the use of serum levels and thus inadequate assessment of aromatase activity.  Aromatase activity does not occur in the serum, it occurs in the tissue, thus saliva would be the best tool.
