Background: Brachial artery doppler fluxometry permits to evaluate the endothelial function in a non-invasive way.
Objective: To know the effect of vasomotor symptoms in brachial artery flux ultrasonographic parameters in Mexican postmenopausal women.
Material And Methods: A prospective study was done including postmenopausal women divided into two groups: I) without hot-flushes and II) with hot-flushes.
Objective: To compare the effects of low and conventional doses of tibolone in brachial artery flux parameters among postmenopausal women.
Methods: Between March 2011 and September 2012, 24 postmenopausal women attending Gynecology and Obstetrics Hospital Luis Castelazo Ayala, Mexico City, for hormone replacement therapy were consecutively recruited. The women were alternately assigned to receive a daily dose of either 2.
Background: Abnormal placentation is a main preeclampsia characteristic. Its cause is a maternal spiral veins trophoblastic invasion failure, which conditions vascular resistances raise and uterus-placental perfusion decrease.
Objective: To determine the relationship between umbilical artery Doppler waveform and adverse perinatal outcome in patients with severe preeclampsia.
Context: It has been proposed that preeclampsia may result from of an imbalance in angiogenic factors. Although prolactin (PRL) is mainly related to lactation, it is also involved in other biological functions, including angiogenesis.
Objective: Our objective was to determine the relationship among preeclampsia, serum and urinary PRL (uPRL) levels, and excretion of antiangiogenic PRL fragments in urine.
