Differences in genetic influence on death from CHD between males and females have been reported. Haemostatic factors have consistently been associated with risk for coronary heart disease (CHD), but sex differences in genetic architecture have not been studied. This study in middle-aged twins investigates whether there are sex differences in...

Objective: This study aimed to compare the effects on hemostasis variables of a contraceptive vaginal ring with those of an oral contraceptive. Study design: Twenty-three and 22 healthy premenopausal women were randomized to the contraceptive vaginal ring (150 μg Nestorone and 15 μg ethinyl estradiol) or Stediril 30 during 3 cycles. Analysis of...

Purpose: In this open-label, randomized study, we assessed the effects on hemostasis of two combined oral contraceptives containing drospirenone (DRSP) as progestogen component. Methods: Three milligrams of DRSP, a progestogen with antimineralocorticoid activity, was combined with either 30 or 20 μg ethinyl estradiol (EE) (DRSP/30EE; DRSP/20EE)...

Alcohol has been hypothesized to promote ovarian carcinogenesis by its potential to increase circulating levels of estrogen and other hormones; through its oxidation byproduct, acetaldehyde, which may act as a cocarcinogen; and by depletion of folate and other nutrients. Case-control and cohort studies have reported conflicting results relating...

Background: Administration of oral contraceptives (OCs) has profound effects on the plasma levels of haemostasis and inflammation variables, resulting in an increased thrombosis risk. Individuals show large differences in the response of these variables to OCs. Polymorphism in the estrogen receptor-1 (ER1) gene may explain part of this inter...

Background: Flow mediated dilatation (FMD) of the brachial artery and soluble intercellular adhesion molecule 1 (sICAM-1) are measures of distinct functions of the endothelium, reflecting nitric oxide (NO)-mediated and pro-inflammatory status, respectively. The comparative value of the two measures in relation to cardiovascular risk is unknown....

This study examined the possible effects of job demands, decision latitude, and job-related social support on risk indicators for cardiovascular disease (CVD) in 165 female nurses. Job strain was measured with the Job Content Questionnaire; CVD risk was measured with insulin, total cholesterol, triglyceride (TG), high-density lipoprotein...

Combined oral contraceptives show clear differences in effect on the tissue factor-initiated coagulation test of activated protein C resistance, which is dependent on the presence and dosage of levonorgestrel. Multiphasic levonorgestrol oral contraceptives differ from monophasic contraceptives and resemble third-generation contraceptives. The...

Background. Oral contraceptives are prescribed as contraception but also as therapy for menstrual cycle disturbances and acne. We studied the prevalence of oral contraceptive (OC) use and the indications to start OC use among adolescents. Methods. A cohort consisting of ninth grade secondary school girls (mean age 15.3 ± 0.6 (s.d.) years)...

Combined oral contraceptives (COCs) have effects on a large number of haemostasis variables. We have summarised literature data on effects of COCs containing 30-35 μg ethinyl estradiol for the third generation of progestogens (PGs): desogestrel, gestodene and norgestimate. It is concluded that about 15 variables show a shift in distribution of...

The objectives of the study were to follow-up six artificial menstrual cycles induced by Triphasil® in order to determine: 1) the time of apparition of B6 metabolic side-effects, in the eventuality they occur, and 2) the existence or non-existence of a normalization process and if so, when it is initiated. The choice of this triphasic OC...
