study finds that HRT given as women transition through menopause has benefiical effect in people with Alzheimer's.  However, when given years later, after menopause, no benefit is found.  In fact, rates increased.  Several flaws with this study.  First, they used synthetic hormones, particularily progestins.  Second, there seems to be no thought that the interpretation of the signal  has changed.  For example, we know that when men have low T, their estrogen receptor status changes from ER beta to ER alpha, which is more proinflammatory.  Third, use bioidentical hormones and compare these to synthetic hormones.

this study revealed increased breast cancer risk in women on "estrogen" and "testosterone" therapy.  Now, several problems here: first, are these synthetic hormone or bioidentical.  Second, the dosages appear, in what is written, to be supra physiologic.  Third, giving supra physiologic estradiol and testosterone will obviously create imbalances and growth potential.  Fourth, how were the women evaluated prior to starting hormone therapy and then were they remonitered (unlikely), fifth, were hormone metabolites evaluated (too, also unlikely).  This study has serious flaws and very little can be extrapolated other than: don't take supra physiologic hormone levels without appropriate evaluation.  Enough said

I look forward to the published results of this study as this abstract references the WHI as the "same entry" criteria.  I imagine the HRT would be the same too, but will wait to see.  There is a serious problem with proper reporting of synthetic estrogens as bioidentical estrogens and synthetic progestins as bioidentical progesterone;  Also, what is the dosage. Most individuals are massively overdosed.  This study was said to be a "landmark".  Could just be don't use synthetic hormones: which is what the WHI said.

Yale study finds estrogen therapy in improves health in women ages 50-59.  The problems with hormone therapy is synthetics and overdosing.  The problem with the WHI was they used medroxy progesterone acetate--a synthetic progestin.   That is not progesterone.  This study estimated that 91,000 + died due to the uneducated view that estrogen HRT is dangerous.  What is dangerous is leaving the HRT and BHRT recommendations to those with conflicts of interest and a lack of knowledge of the science.

Study compared bioidentical progesterone (micronized progesterone) to a synthetic progestin in the inhibition of endometrial hyperplasia progression.  The study found that the synthetic progestin worked best, but they both inhibited progression of the endometrial hyperplasia when followed out to 3 months therapy.

Women with SLE enter menopause earlier.  This study comments on the need for hormone testing in women with SLE and appropriate therapy as indicated.  This study recommended against estrogen therapy due to studies revealing increased flares.  The problem with those studies is that they looked at OCPs and synthetic HRT.

BHRT and/or synthetic hormones not associated with increased breast cancer (RR 0.72), all cause mortality (RR 0.77).  

Testosterone therapy is complex in hypogonadism.  Much of the marketing-based medicine of Low T today is in fact doping.  Increasing weight is clearly associated with a declining T level in men.  Testosterone therapy should be approach individually and therapies that use the one size fits all approach never work.  This is the case whether the use of synthetics or natural hormones are employed.  Testosterone has been shown to improve dysglycemia, MetS, reduce fat and increase muscle mass.  

This is the perfect study to compare synthetic, unnatural hormones with bioidentical hormones.  Premarin was compared with bioidentical estradiol.  Premarin reduced the endothelial NO synthase transcription and activity by 30-50% compared to Estradiol.   Thus, premarin results in a lower NO production and thus greater endothelial dysfunction compared to Estradiol.

HRT, particularily estrogen therapy, is shown to increase mild to moderate flares of lupus.

study of 80,377 postmenopausal women found no increase/decrease in breast cancer in women on estradiol and progesterone (RR 1.0).  However, estradiol and provera (synthetic progestin) found a 69% increased breast cancer risk (RR 1.69).

bioidentical progesterone lowers breast cancer risk; synthetic progestins increase breast cancer risk

No surprise that progesterone and the synthetic progestin medroxyprogesterone acetate (MPA) have different effects on the vascular endothelium. MPA inhibits NO production, whereas Progesterone maintains NO production.  MPA promoted platelet adhesion whereas Progesterone did not--significant implication in plaque formation.

Study finds that estradiol combined with synthetic progestin increased CRP.  No surprise.

synthetic progestins stimulate breast cancer

synthetic progestins increase breast cancer risk

watch out!  bioidentical progesterone provides improved symptom control versus synthetic progestin MPA

Estradiol has been shown to have positive health effects on vascular endothelium.  The synthetic progestin, medroxyprogesterone acetate, negates this.  

Premarin and provera together increase risk of breast cancer development
