In the WHI study, what major clinical outcomes were increased risk with use of Estrogen alone (hysterectomy)?
Increase stroke and venous thromboembolism.
What were the two critical factors in determining whether hormone therapy reduces or increases risk of CHD?
Time since menopause (within 10 yrs of last period) and age of initiation (<60)
Which age range and group (estrogen only vs E+P) had favorable outcomes for absolute risk of health outcomes by the WHI?

B. 50-59y
C. 60-69y
B. Estrogen only
Women with intact uterus was significantly associated with a (higher/lower) risk of breast cancer
higher
Women with prior hysterectomy had (higher/lower) risk of breast cancer
lower
What drugs are associated with continuous cyclic therapy?
Premphase (oral) and Combipatch (Transdermal)
How does continuous cyclic therapy (Sequential treatment) work? How is it viewed?
Estrogen admin daily, progesterone 12-14 days of 28 day cycle
Scheduled withdrawal bleeding- not favorable
Preferred in recently menopausal women (not long term)
How does continuous long cycle therapy (cyclic withdrawal) work? How is it viewed?
Estrogen daily, Progesterone 12-14 days every other month
Limited safety data and endometrial protection unclear, RARE
How does continuous combines therapy work? How is it viewed?
Daily E+P: Preferred!
Stops bleeding, recommended for women >2 yrs post-final period, long term endo protection

Prempro, Angeliq, Activella, Amabelz, Mimvey, Bijuva, Fyavolv, Jinteli
(PAAAM Be for Jim -Michael Scott Tarzan voice)
What are the 2 continuous combined E+P transdermal products?
ClimaraPro and Combipatch
How does intermittent combined (pulsed-progesterone) work? How is it viewed?
3 days estrogen, 3 days E+P
Pulse prevents progesterone receptors, endo protection unknown
What drug is used for intermittent combined E+P?
Prefest-Oral
What oral E+P is best for endometrial protection?
Medroxyprogesterone (Provera), Norethindrone acetate (Aygestin), and micronized progestin (Prometrium) (PAP)
What vaginal/intrauterine E+P is best for endometrial protection?
levonorgestrel (Mirena IUD) and progesterone gel (Crinone)
What drug is used for Estrogen+SERM? What are the side effects?
Duavee-oral
GI track disrders, muscle spasm, neck pain, dizziness, oropharyngeal pain
What SSRI is FDA approved for hot flashes?
Paroxetine
What drug is used for bio-identical hormone replacement therapy? How is it viewed?
Bijuva-oral
Minimal insurance coverage and questionable safety
What is the first line treatment for Genitourinary Syndrome of Menopause? Second line?
First line: non-hormonal (Lubricants and vaginal moisturizers)
Second line: estrogen (topical, low dose oral contra)
What drug is used in the treatment of mod-severe dyspareunia using SERM? What are important clinical pearls?
Ospemifene (Osphena)
Black box: endo cancer, stroke, VTW
In postmenopausal women
SE: endo hyperplasia and hot flashes
What drug is used in the treatment of mod-severe dyspareunia using DHEA? What are important clinical pearls?
Prasterone (Intrarosa)
Postmenopausal women
Contraindicated for undiagnosed vaginal bleeding
Avoid with history of breast cancer
Costly
Hormone produced by C-cells that help regulate calcium and phosphate levels in the blood
calcitonin
Main hormone secreted from thyroid gland into the blood stream, controlling basal metabolic rate
Thyroxine
Which is more potent: T4 or T3?
T3
Which is produced more: T4 or T3?
T4
How is thyroid biosynthesized? (Iodide to T3 and T4)
Iodide in blood pairs with sodium to go through Na/I symporter into thyroid follicular cell
In follicular cell, iodide is pushed through pendrin to follicle colloid, meanwhile thyroglobulin is taken from the ER of cell and undergoes exocytosis into follicle colloid
In follicle colloid, Iodide gets oxidized and attaches to the aromatic rings of thyroglobulin
Once attached, complex undergoes endocytosis where it goes through proteolysis which separates into T3 and T4 in transport of follicular cell
Cell goes back into blood stream with T3 and T4
What makes T3 and T4 from MIT and DIT?
MIT + DIT= T3
DIT + DIT= T4
