, The incidence of obesity, which is a chronic condition, has increased in recent years. The association between obesity and female sexual dysfunction remains unclear, particularly in postmenopausal women. In the present study, we evaluated whether obesity is a risk factor for sexual dysfunction in postmenopausal women.
This is a cross-sectional study that analyzed data from interviews of postmenopausal women at the Climacteric Outpatient Clinic from 2015 to 2018. After applying the inclusion and exclusion criteria, 221 women aged between 40 and 65 years old were selected and invited to participate in the study. Obesity was diagnosed according to body mass index (BMI). The participants were grouped into the following BMI categories: group 1, 18.5-24.9 kg/m2 (normal); group 2, 25.0- 29.9 kg/m2 (overweight); and group 3, ≥30.0 kg/m2 (obese). Sexual function was assessed using the Female Sexual Function Index (FSFI) questionnaire. Cutoff points of ≥23 and ≥26.5 were adopted to define a diagnosis of female sexual dysfunction (FSD) based on the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision by the American Psychiatric Association (DSM-IV-TR).
The desire and arousal scores were statistically higher in the normal BMI group than in the obese group (p=0.028 and p=0.043, respectively). The satisfaction scores were statistically higher in the normal BMI group than in the overweight and obese groups (p<0.05). The total FSFI score statistically differed among the BMI categories (p=0.027).
In the present study, obese and overweight postmenopausal women had higher total scores than women with normal BMI. Our results show that obese and overweight postmenopausal women had a higher index of dysfunction in desire and arousal and lower sexual satisfaction than normal-weight women.

To evaluate the antifungal susceptibility profile of the aqueous extract of the bark of Schinus terebinthifolius Raddi against the strains of the genus Candida.
By using the disk diffusion method, 50 samples of the genus Candida (Candida albicans; Candida krusei; Candida glabrata; and Candida tropicalis), isolated from patients receiving treatment at Hospital Santa Casa de Misericórdia de São Paulo, and 1 American Type Culture Collection (ATCC) sample of each species were tested against: the isolated aqueous extract of the bark of Schinus terebinthifolius Raddi, isolated nystatin, and the association of nystatin and the aqueous extract of Schinus terebinthifolius Raddi.
There were no significant differences regarding the different strains of Candida tested. In the presence of the aqueous extract of Schinus terebinthifolius Raddi, no inhibition halo was visible. Isolated nystatin formed an inhibition halo measuring respectively 18.50 mm and 19.50 mm for the Candida albicans species and the others referred to as non-Candida albicans (Candida krusei; Candida glabrata; and Candida tropicalis). The association of nystatin and the aqueous extract of Schinus terebinthifolius Raddi resulted in inhibition halos measuring 14.25 mm and 16.50 mm respectively. The comparisons of these results are statistically significant (p < 0,001).
The aqueous extract of Schinus terebinthifolius Raddi showed no antifun-gal activity in vitro against the strains tested, whereas the association of nystatin and the aqueous extract of Schinus terebinthifolius Raddi caused a decrease in the inhibition halo when compared with isolated nystatin.

The aim of this study was to study the effects of Tribulus terrestris on sexual function in menopausal women.
This was a prospective, randomized, double-blind, placebo-controlled clinical trial that included 60 postmenopausal women with sexual dysfunction. The women were divided into two groups, placebo group and Tribulus group, and evaluated by using the Sexual Quotient-female version (SQ-F) and Female Intervention Efficacy Index (FIEI) questionnaires.
There was no significant difference between the groups in age, age at menopause, civil status, race, and religion. In the evaluation with the SQ-F questionnaire, there were significant differences between the placebo (7.6±3.2) and Tribulus (10.2±3.2) groups in the domains of desire and sexual interest (p d" 0.001), foreplay (3.3±1.5 versus 4.2±1.0) (p d" 0.01), arousal and harmonious interaction with the partner (5.7±2.1 versus 7.2±2.6) (p d" 0.01), and comfort in sexual intercourse (6.5±2.4 versus 8.0±1.9) (p d" 0.01). There was no significant difference between the placebo and Tribulus groups in the domains of orgasm and sexual satisfaction (p = 0.28). In the FIEI questionnaire, there was a significant improvement (p < 0.001) in the domains of vaginal lubrication during coitus and/or foreplay (20 versus 83.3%), sensation in the genitalia during sexual intercourse or other stimuli (16.7 versus 76.7%), sensation in the genital region (20 versus 70%), sexual intercourse and/or other sexual stimulations (13.3 versus 43.3%), and the ability to reach orgasm (20% versus 73.3%). There was no significant difference in adverse effects between the two groups.
After 90 days of treatment, at the doses used, we found Tribulus terrestris to be effective in treating sexual problems among menopausal women.

PURPOSE: To evaluate sexual function in postmenopausal women diagnosed with metabolic syndrome. METHODS: Case-control study with 195 postmenopausal women (amenorrhea ≥1 year, FSH≥30 mIU/mL, aged 43 to 69 years) seen at the Department of Obstetrics and Gynecology, School of Medical Sciences of Santa Casa de São Paulo and in the Basic Units of the Family Health Program of São Paulo. Clinical data were collected, and body mass index and waist circumference were evaluated. Total cholesterol, HDL and LDL cholesterols, triglycerides, and fasting glucose were determined for biochemical analysis. We considered women to have the metabolic syndrome when they met three or more diagnostic criteria: waist circumference>88 cm and triglycerides ≥150 mg/dL; cholesterol HDL <50 mg/dL; blood pressure ≥130/85 mmHg, and fasting glucose ≥110 mg/dL. The participants were divided into Control Group (n=87) and Metabolic Syndrome Group (n=108). The Female Sexual Function Index (FSFI) was employed to assess the sexual function. RESULTS: Mean age was 54.0±4.7 years. The rate of sexual dysfunction was significantly higher in women with the metabolic syndrome than in the Control Group, both when considering FSFI <26.5 (90/108 [83.3%] versus 42/87 [48.2%], p<0.0001) and FSFI <23 (62/108 [57.4%] versus 16/87 [18.39%], p<0.001). The domains desire, arousal, lubrication, orgasm (p<0.001), and satisfaction (p=0.002) had lower scores in women with the metabolic syndrome. For the pain scores, there was no significant difference (p=0.57) between groups. All components of the metabolic syndrome diagnosis were associated with higher levels of sexual dysfunction (p<0.001). CONCLUSION: Postmenopausal women with metabolic syndrome present more frequently sexual dysfunction than those of the same age who do not have it.

PURPOSE: to evaluate the effects of tamoxifen on the expression of TGF-β and p27 proteins in polyps and adjacent endometrium of women after menopause. METHODS: prospective study with 30 post-menopausal women with diagnosis of breast cancer, taking tamoxifen (20 mg/day), presenting diagnosis of suspect endometrial polyps through transvaginal ultrasonography, and submitted to diagnostic and surgical hysterectomy to withdraw the polyps and adjacent endometrium. A immunohistochemical study has been done to verify the expression of the TGF-β and p27 proteins in the polyps and adjacent endometrium. These proteins' quantification has been done by morphometry. RESULTS: the patients' average age was 61.7 years old; their average age at the menopause onset was 49.5; and the average of using tamoxifen was 25.3 months. The average concentration of positive cells for TGF-β protein in the glandular and stroma polyp epithelium was 62.6±4.5 cells/mm². For the p27, in the glandular polyp epithelium, it was 24.2±18.6 cells/mm² and for the stroma, 19.2±15.2 cells/mm². There was no significant difference between the expression of TGF-β and p27 in the glandular epithelial form the polyps and the adjacent endometrium. The expression of proteins in the polyp and adjacent endometrium with its respective glandular and stroma epithelium showed a significant difference for the p27 protein (r=0.9, p<0.05). CONCLUSIONS: we have concluded that the TGF-β expression is not related to the effect of tamoxifen on the growing of endometrial polyps, but the absence of polyps' malignization by tamoxifen may be explained by the high expression of p27 protein in its glandular epithelium.

PURPOSE: to quantify the presence of antithyroperoxidase (anti-TPO) and antithyroglobulin (anti-TG) antibodies, and the plasmatic concentrations of thyrotropin (TSH) and free thyroxine (FT4) in normal pregnant women. METHODS: a hundred twenty-seven pregnant women, residing in São Paulo, aged from 14 to 44 years old and gestational age > 16 weeks, determined by ultrasound performed before the 20th week of pregnancy were included in a transversal study performed in the prenatal clinic of Santa Casa de Misericórdia de São Paulo, from January 2003 to September 2004. Pregnant women using medicines or with thyroidopathy history were excluded. Antithyroperoxidase and antithyroglobulin antibodies were quantified by chemiluminescence immunoassay. The immunofluorimetry technique by time-resolved was used for determining the thyrotrophin and free thyroxine. The Student's t test, with significance of 5%, was used for analyzing the results. RESULTS: the frequency of antithyroid antibodies was 12.6% (8.6% of anti-TPO antibodies, and 4.6% of anti-TG antibodies). The average of TSH concentrations was 2.13±1.0 µU/ml, and the average of T4L was 0.9±0.5 ng/dl. It was observed alteration of the thyroid function in ten pregnant women (8%). Three of them had diagnosis of hypothyroidism: one in the clinical form of the disease, with increased TSH and decreased FT4; two in the subclinical form with increased TSH and normal FT4. Five presented decreased TSH and increased FT4, consistent with clinical hyperthyroidism and two were diagnosed with subclinical hyperthyroidism, with decreased TSH concentrations only. CONCLUSIONS: the frequency of antithyroid antibodies was 12.6% in pregnant women, the antithyroperoxidase antibodies being predominant over the antithyroglobulin antibodies. It was observed some thyroid dysfunction in 8% of the cases with alterations of TSH and/or T4L.

PURPOSE: to evaluate oxidative stress in cardiac tissue of ovariectomized rats, with and without hormonal therapy. METHODS: female Wistar rats were divided in three groups: control group (CG); ovariectomized group (OG); ovariectomized group with estrogen supplementation (ESG). The estrogen deprivation was done through bilateral ovariectomy. After one week from the ovariectomy, a pellet of 1.5 mg of 17beta-estradiol was implanted in the ESG animals. Nine weeks after the ovariectomy, cardiac tissue was obtained for the analysis of the oxidative stress through CL (chemiluminescence), and measurement of antioxidant enzymes catalase (CAT), superoxide dismutase (SOD) and gluthatione peroxidase (GPx). RESULTS: CL was increased in the OG (7348±312 cps/mg protein) when compared with the CG (6250±41 cps/mg protein, p<0.01), but there was no significant difference between the CG and the ESG (6170±237 cps/mg protein). Ovariectomy reduced SOD (35%, p<0.05) and CAT (22%, p<0.001) activities in the OG as compared with the CG. Hormonal therapy normalized antioxidant enzymes activities in the ESG. There was no statistically significant difference in GPx activity among the groups studied. CONCLUSIONS: ovarian hormone deprivation induced an increase of oxidative stress with reduction of antioxidant defenses in the cardiac tissue. However, hormonal therapy prevented oxidative stress after ovariectomy, probably due to an increase of the CAT and SOD activities in the cardiac muscle. These findings suggest an important oxidative stress contribution in cardiovascular dysfunctions observed in women after menopause, reinforcing the importance of hormonal therapy in the management of cardiovascular diseases risk in this group of women.
