- Aerobic training abolishes ambulatory blood pressure increase induced by estrogen therapy: A double blind randomized clinical trial(2011) CARDOSO JR., Crivaldo Gomes; ROSAS, Fabricio Collares; ONEDA, Bruna; LABES, Eliana; TINUCCI, Tais; ABRAHAO, Sandra Balieiro; FONSECA, Angela Maggio da; MION JR., Decio; FORJAZ, Claudia Lucia de MoraesEmerging data reveal that oral estrogen therapy can increase clinic blood pressure (BP) in postmenopausal women; however, it is important to establish its effects on ambulatory BP, which is a better predictor for target-organ damage. Besides estrogen therapy, aerobic training is widely recommended for post-menopausal women, and it can decrease ambulatory BP levels. This study was designed to evaluate the effect of aerobic training and estrogen therapy on the ambulatory BP of post-menopausal women. Forty seven healthy hysterectomized women were randomly divided (in a double-blind manner) into 4 groups: placebo-control (PLA-CO = 12), estrogen therapy-control (ET-CO = 14), placebo-aerobic training (PLA-AT = 12), and estrogen therapy-aerobic training (ET-AT = 09). The ET groups received estradiol valerate (1 mg/day) and the AT groups performed cycle ergometer, 3x/week at moderate intensity. Hormonal status (blood analysis), maximal cardiopulmonary exercise test (VO(2) peak) and ambulatory BP (24-h, daytime and nighttime) was evaluated before and 6 months after interventions. A significant increase in VO(2) peak was observed only in women who participated in aerobic training groups (+4.6 +/- 1.0 ml kg(-1) min(-1), P=0.00). Follicle-stimulating hormone was a significant decreased in the ET groups (-18.65 +/- 5.19 pg/ml, P=0.00), and it was accompanied by an increase in circulating estrogen (56.1 +/- 6.6 pg/ml). A significant increase was observed in the ET groups for daytime (P=0.01) and nighttime systolic BP (P=0.01), as well as nighttime diastolic BP (P = 0.02). However, daytime diastolic BP was increased only in the ET-CO group (+3.4 +/- 1.2 mmHg, P=0.04), and did not change in any other groups. No significant effect was found in ambulatory heart rate. In conclusion, aerobic training abolished the increase of daytime ambulatory BP induced by estrogen therapy in hysterectomized, healthy, normotensive and postmenopausal women.
- Acupuncture-ameliorated menopausal symptoms: single-blind, placebo-controlled, randomized trial(2011) LUCA, A. Castelo Branco de; FONSECA, A. Maggio da; LOPES, C. M. Carvalho; BAGNOLI, V. R.; SOARES JR., J. M.; BARACAT, E. C.Objectives To evaluate the effects of acupuncture and sham-acupuncture on women with menopausal symptoms as reflected in the intensity of their hot flushes and the Kupperman Menopausal Index (KMI). Method This was a randomized, single-blind, placebo-controlled, cross-over trial with 81 patients assigned to two groups: Group 1 received 12 months of acupuncture, then 6 months of sham-acupuncture treatment (n = 56) and Group 2 received 6 months of sham-acupuncture, then 12 months of acupuncture treatment (n = 25). The needles were inserted in a harmonic craniocaudal manner at a depth of about 2 cm, and each session lasted approximately 40 min. The efficacy of acupuncture in ameliorating the climacteric symptoms of patients in postmenopause was determined through the KMI and the intensity of hot flushes. The analysis of variance method for two factors and repeated measures was applied. Results The baseline values of the women in both groups were similar for the KMI score and number of hot flushes. At the end of 6 months, the values for the KMI and hot flushes for the women in Group 1 were lower than those of the women in Group 2 (p < 0.05). After 12 months, the KMI and hot flush data were similar in both groups. After 18 months, the values of the KMI and hot flushes for the women in Group 2 for were lower than those of the women in Group 1 (p < 0.05). Conclusion Acupuncture treatment for relieving menopausal symptoms may be effective for decreasing hot flushes and the KMI score in postmenopausal women.
article 6 Citação(ões) na Scopus Transdermal estrogen therapy effects on fibrinogen levels in women with a past history of venous thromboembolism: a pilot study(2011) MARGARIDO, P. F. R.; BAGNOLI, V. R.; FONSECA, A. Maggio da; MACIEL, G. A. R.; SOARES JR., J. M.; D'AMICO, E. A.; BARACAT, E. C.Objective: To evaluate thromboelastographic parameters and fibrinogen levels in women treated with transdermal 17 beta estradiol. Methods: 29 menopausal women with a history of venous thromboembolic disease were included. Nine patients composed the treatment (HT) group and 20 the control group. Coagulation was assessed by thromboelastography in samples of whole blood and platelet-poor plasma (PPP). The following thromboelastographic variables were measured: time for initial coagulation (R), blood clotting speed (K and the a angle), clot tensile strength (MA and G), global index of coagulation (Cl) and fibrinolysis (LY30) and fibrinogen levels. Results: There were no differences in the other parameters comparing both groups. Fibrinogen levels showed a 13.77 +/- 19.94% reduction in the HT group and a 5.51 +/- 8.09% increase in the control group after 6 months. Conclusions: Our data suggested that transdermal estrogen may not increase blood coagulability, but that it reduces fibrinogen levels in FIT women.- Dyslipidemia in women with polycystic ovary syndrome: incidence, pattern and predictors(2011) ROCHA, Michelle P.; MARCONDES, Jose A. M.; BARCELLOS, Cristiano R. G.; HAYASHIDA, Sylvia A. Y.; CURI, Daniela D. G.; FONSECA, Angela M. da; BAGNOLI, Vicente R.; BARACAT, Edmund C.One hundred forty-two women with polycystic ovary syndrome (PCOS) with an average body mass index (BMI) of 29.1 kg/m(2) and average age of 25.12 years were studied. By BMI, 30.2% were normal, 38.0% were overweight and 31.6% were obese. Thirty-one eumenorrheic women matched for BMI and age, with no evidence of hyperandrogenism, were recruited as controls. The incidence of dyslipidemia in the PCOS group was twice that of the Control group (76.1% versus 32.25%). The most frequent abnormalities were low high-density lipoprotein cholesterol (HDL-C; 57.6%) and high triglyceride (TG) (28.3%). HDL-C was significantly lower in all subgroups of women with PCOS when compared to the subgroups of normal women. No significant differences were seen in the total cholesterol (p = 0.307), low-density lipoprotein cholesterol (LDL-C; p = 0.283) and TGs (p = 0.113) levels among the subgroups. An independent effect on HDL-C was detected for glucose (p = 0.004) and fasting insulin (p = 0.01); on TG for age (p = 0.003) and homeostatic model assessment insulin resistance (p = 0.03) and on total cholesterol and LDL-C for age (p = 0.02 and p = 0.033, respectively). In conclusion, dyslipidemia is common in women with PCOS, mainly due to low HDL-C levels. BMI has a significant impact on this abnormality.
- The effects of cinnarizine on menopausal symptoms in women(2011) CEZARINO, P. Y.; BAGNOLI, V. R.; FONSECA, A. M.; SOARES JR., J. M.; BARACAT, E. C.Objective To evaluate the effectiveness and safety of cinnarizine in the treatment of menopausal symptoms. Design A total of 100 climacteric and symptomatic women participated in a double-blind, placebo-controlled study. They were divided into two groups of the same size: Gcin, intake of 25 mg of cinnarizine every 12 h for 6 months (n = 50); and Gpla, placebo intake every 12 hours for 6 months (n = 50). Menopausal symptoms were evaluated according to the Kupperman menopausal index on the first visit and at 6 months of treatment. A total of 62 women completed the study: 27 from the Gcin group and 35 from the Gpla group. Results Based on the Kupperman menopausal index, there were no statistically significant differences between the two groups before and after the treatment. Conclusion Our data suggest cinnarizine is not effective on menopausal symptoms because it had no more efficacy than placebo.
- Influence of LH and high-density lipoprotein cholesterol (HDL-C) on metformin response in women with polycystic ovary syndrome(2011) MACIEL, Gustavo Arantes Rosa; HAYASHIDA, Sylvia Asaka Yamashita; COSTA, Lia Cruz Vaz da; MARCONDES, Jose Antonio Miguel; FONSECA, Angela Maggio da; SOARES JR., Jose Maria; BARACAT, Edmund ChadaObjective: To search for predictors of metformin response in women with polycystic ovary syndrome (PCOS) through a detailed analysis of clinical and laboratory parameters. Study design: We designed a prospective study to investigate clinical and laboratory parameters to search for predictors of metformin response in women with PCOS. A total of 53 PCOS patients were given metformin 850 mg twice a day for 6 months, after which patients were classified as responders or non-responders. Parameters analyzed for comparison between the two groups were: plasma fasting insulin glucose/insulin ratio; oral glucose tolerance test (OGTT) with insulin (120 min); HOMA and QUICKI tests; total cholesterol and fractions, triglycerides; LH, FSH, estradiol, progesterone, testosterone, androstenedione, 17-OH progesterone, and DHEAS. Results: From all patients, 30(56.6%) were responders and 23(43.3%) were non-responders. Multinomial analysis showed that the positive response to metformin was associated with higher levels of basal LH (p = 0.038) and lower levels of high-density lipoprotein cholesterol (HDL-C) (p = 0.015). Conclusion: In weight-matched PCOS subjects, laboratory markers might predict the metformin response. Higher levels of basal LH and lower levels of HDL-C are correlated with a positive response to metformin treatment in PCOS subjects.
