Effect of low-dose combined oral contraceptive on aerobic capacity and anaerobic threshold level in active and sedentary young women

Background: The purpose of this study was to evaluate the effect of long-term use of oral contraceptives (DC) containing 0.20 mg of ethinylestradiol (EE) combined with 0.15 mg of gestodene (GEST) on the peak aerobic capacity and at the anaerobic threshold (AT) level in active and sedentary young women. Study Design: Eighty-eight women (23 +/- 2.1 years old) were divided into four groups active-OC (G1), active-NOC (G2), sedentary-OC (G3) and sedentary-NOC (G4) and were submitted to a continuous ergospirometric incremental test on a cycloergometer with 20 to 25 W min(-1) increments. Data were analyzed by two-way ANOVA with Tukey post hoc test. Level of significance was set at 5%. Results: The OC use effect for the variables relative and absolute oxygen uptake VO(2) mL kg(-1) min(-1); VO(2), L min(-1), respectively), carbon dioxide output (VCO(2), L min(-1)), ventilation (VE, L min(-1)), heart rate (HR, bpm), respiratory exchange ratio (RER) and power output (W) data, as well as the interaction between OC use and exercise effect on the peak of test and at the AT level did not differ significantly between the active groups (G1 and G2) and the sedentary groups (G3 and G4). As to the exercise effect, for all variables studied, it was noted that the active groups presented higher values for the variables VO(2), VCO(2), VE and power output (p<.05) than the sedentary groups. The RER and HR were similar (p>.05) at the peak and at the AT level between G1 vs. G3 and G2 vs. G4. Conclusions: Long-term use of OC containing EE 0.20 mg plus GEST 0.15 mg does not affect aerobic capacity at the peak and at the AT level of exercise tests. (C) 2010 Elsevier Inc.

Importance of Pelvic Muscle Tenderness Evaluation in Women with Chronic Pelvic Pain

Objective. To determine the prevalence of pelvic muscle tenderness in women with chronic pelvic pain (CPP) and to assess the importance of evaluating muscle tenderness in such women. Design. Observational study of 48 healthy female volunteers and 108 women with CPP, who were clinically evaluated for pelvic muscle tenderness by two researchers blinded to all clinical data. Results. The frequency of clinically detected pelvic muscle tenderness was significantly higher in women with CPP than in healthy volunteers (58.3% vs 4.2%, P < 0.001). Among women with CPP, those with pelvic muscle tenderness had higher Beck Depression Index scores (22 [6-42] vs 13 [3-39], P = 0.02) and higher rates of dyspareunia (63.5% [40/63] vs 28.9% [13/45], P < 0.004) and constipation (46.0% [29/63] vs 26.7% [12/45], P = 0.05) than those without pelvic muscle tenderness. Conclusion. Tenderness of pelvic muscles was highly prevalent among women with CPP and was associated with higher BDI scores and higher rates of dyspareunia and constipation. Determination of pelvic muscle tenderness may help in identifying women who require more intense treatment for CPP.

Increased arterial stiffness in nonobese women with polycystic ovary syndrome (PCOS) without comorbidities: one more characteristic inherent to the syndrome?

Background Polycystic ovary syndrome (PCOS) is associated with adverse metabolic effects. Some cardiovascular disease (CVD) risk markers are increased in women with PCOS. However, early markers of atherosclerosis are also associated with obesity and insulin resistance, which are related to PCOS. These markers may result either directly from PCOS or indirectly as a consequence of the comorbidities associated with the syndrome. Context To assess the presence of early CVD markers in young, nonobese women with PCOS. Patients Forty women with PCOS and 50 healthy women with regular menstrual cycles, matched for age and body mass index (BMI). Measurements The following CVD markers were assessed by ultrasonography: common carotid artery (CCA) stiffness index (beta), distensibility and intima-media thickness (IMT), and brachial artery flow-mediated dilatation (FMD). Inflammatory markers, including interleukin (IL)-6, tumour necrosis factor (TNF)-alpha, homocysteine, C-reactive protein (CRP), glycaemia, lipid profile and insulin, were also assessed. Results CCA beta was higher in PCOS than in control women (3 center dot 72 +/- 0 center dot 96 vs. 3 center dot 36 +/- 0 center dot 96, P = 0 center dot 04) and CCA distensibility was lower (0 center dot 31 +/- 0 center dot 08 vs. 0 center dot 35 +/- 0 center dot 09 mmHg(-1), P = 0 center dot 02). Waist circumference, total testosterone and the Free Androgen Index (FAI) were higher in PCOS patients than in controls (78 center dot 2 +/- 10 center dot 0 vs. 71 center dot 5 +/- 7 center dot 2 cm, P = 0 center dot 001; 88 center dot 1 +/- 32 center dot 4 vs. 57 center dot 1 +/- 21 center dot 2 ng/dl, P < 0 center dot 01; 12 center dot 7 +/- 15 center dot 7%vs. 4 center dot 7 +/- 2 center dot 3%, P < 0 center dot 01, respectively), while SHBG was reduced (37 center dot 9 +/- 19 center dot 1 vs. 47 center dot 8 +/- 18 center dot 3 nmol/l, P = 0 center dot 01). The remaining variables did not differ between the groups. Conclusions Young women with PCOS exhibit changes in vascular elasticity even in the absence of classical risk factors for CVD, such as hypertension and obesity.

Distribution of fentanyl in the placental intervillous space and in the different maternal and fetal compartments in term pregnant women

Fentanyl is used in obstetrical practice to promote analgesia and anesthesia during labor and in cesarean delivery, with rapid and short-term effects. To determine fentanyl concentrations in maternal plasma, in the placental intervillous space, and in the umbilical artery and vein in term pregnant women. Ten healthy pregnant women underwent epidural anesthesia with fentanyl plus bupivacaine and lidocaine, and fentanyl concentrations were determined in the various maternal and fetal compartments, including the placental intervillous space, which has not been previously studied in the literature. The ratios of fentanyl concentrations in the various maternal and fetal compartments revealed an 86% rate of placental fentanyl transfer. The highest fentanyl concentrations were detected in the placental intervillous space, being 2.19 times higher than in maternal plasma, 2.8 times higher than in the umbilical vein and 3.6 times higher than in the umbilical artery, with no significant differences between the umbilical vein and artery, demonstrating that there was no drug uptake by fetal tissues nor metabolism of the drug by the fetus despite the high rates of placental transfer. The present study demonstrated that the placental intervillous space acted as a site of fentanyl deposit, a fact that may be explained by two hypotheses: (1) the blood collected from the placental intervillous space is arterial and, according to some investigators, the arterial plasma concentrations of the drugs administered to patients undergoing epidural anesthesia are higher than the venous concentrations, and (2) a possible role of P-glycoprotein (P-gp).

Glycodelin expression in the endometrium of healthy women and in the eutopic and ectopic endometrium of women with endometriosis

Objective: To analyze the expression of the glycodelin gene to better understand the molecular environment of endometriotic lesions and to elucidate the potential mechanisms that underlie the complex physiopathology of endometriosis. Design: Prospective laboratory study. Setting: University hospital. Patient(s): Eleven healthy fertile women and 17 patients with endometriosis in the early proliferative phase of the menstrual cycle. Intervention(s): Endometrial biopsy specimens were obtained from the endometrium of healthy women without endometriosis (controls) and from eutopic and ectopic endometrium tissues (pelvic and ovarian endometriotic implants) of endometriosis patients. Main Outcome Measure(s): The glycodelin relative expression level by real-time polymerase chain reaction (PCR) analysis. Result(s): The glycodelin down-regulation found in the endometriotic lesions was 332.26 and 123.17-fold lower, respectively, when compared with the eutopic tissue and the control endometrium. Conclusion(s): Glycodelin may be one of the molecules that contributes to the loss of cellular homeostasis in endometriotic lesions. (Fertil Steril (R) 2009;91:1676-80.

High levels of anxiety and depression have a negative effect on quality of life of women with chronic pelvic pain

Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with consequent difficulty in diagnosis and treatment. Patients with CPP have high levels of anxiety and depression, with a consequent impairment of their quality of life. The objective of this study was to determine the prevalence of anxiety and depression and their impact on the quality of life of women with CPP. A cross-sectional controlled study was conducted on 52 patients with CPP and 54 women without pain. Depression and anxiety were evaluated by the Hospital Anxiety and Depression Scale, and quality of life was evaluated by the World Health Organization Quality of life Whoqol-bref questionnaire. Data were analysed statistically by the Mann-Whitney U-test, the Fisher exact test, chi-square test and Spearman correlation test. The prevalence of anxiety was 73% and 37% in the CPP and control groups, respectively, and the prevalence of depression was 40% and 30% respectively. Significant differences between groups were observed in the physical, psychological and social domains. Patients with higher anxiety and depression scores present lower quality of life scores. The fact that DPC is a syndromic complex, many patients enter a chronic cycle of search for improvement of medical symptoms. The constant presence of pain may be responsible for affective changes in dynamics, family, social and sexual. Initially the person is facing the loss of a healthy body and active, to a state of dependence and limitations. In this study, patients with higher scores of anxiety and depression scores had lower quality of life and patients with lower scores of anxiety and depression had scores of quality of life. These results show that perhaps the depression and anxiety may be related to the negative impact on quality of life of these patients. In view of this association, we emphasise the importance of a specific approach to the treatment of anxiety and depression together with clinical treatment to improve the quality of life of these patients.

Increased Capsaicin Receptor TRPV1 in the Peritoneum of Women With Chronic Pelvic Pain

Objective: To investigate the expression of capsaicin receptor [transient receptor potential vanilloid type-1 (TRPV1)] in the peritoneum of women with chronic pelvic pain (CPP). Methods: A case-control study was conducted on 25 women with CPP and 10 controls. Samples of the rectouterine excavation (2 cm 2) were obtained by laparoscopy, fixed in 4% formaldehyde, and underwent immunohistochemistry analysis using rabbit anti-TRPV1 (1:400) polyclonal antibodies and anti-protein gene product 9.5 (PGP 9.5) (1:2000) as a neuronal marker. Ten sequential images of high magnification fields ( x 40) were captured from each slide and the area identified with the antibody was calculated with Kontron V2.0 software. Results: Immunoreactivity to TRPV1 was sparsely detected in the nervous tissue and epithelium of endometriotic lesions. The percent area of immunoreactivity for TRPV1 [expressed as median (range)] was greater in specimens from women with CPP, 1.02% (0.54 to 2.93), than from women without the disease, 0.14% (0.07 to 1.12) (P<0.0001). This greater expression was not secondary to an increase in neuronal fibers because there was also a significant difference in the percent area TRPV1:PGP 9.5 ratio between women with CPP, 1.18 (0.26 to 4.63), and controls, 0.15 (0.06 to 0.95) (P = 0.0003). Discussion: TRPV1 may play an important role in the maintenance and perpetuation of symptoms in women with CPP. In view of the immunoreactivity detected for TRPV1, the endometriotic lesion may have the ability to interfere with nociception or with the inflammatory peritoneal environment in women with CPP. Further Studies are needed to elucidate the participation of TRPV1 in CPP and its association with endometriosis.

Supplemented tissue culture medium 199 is a better medium for in vitro maturation of oocytes from women with polycystic ovary syndrome women than human tubal fluid

Objective: To compare oocyte maturation, fertilization and cleavage rates, and embryonic developmental quality after culture of human immature oocytes from polycystic ovary syndrome (PCOS) patients in human tubal fluid (HTF) or tissue culture medium (TCM) 199. Design: Prospective, randomized, controlled trial. Setting: University hospital. Patient(s): Thirteen women undergoing 23 in vitro maturation cycles, from whom 119 oocytes were retrieved. Intervention(s): Cumulus-enclosed germinal vesicle-stage oocytes matured in TCM-199-supplemented or HTF-supplemented media. Main Outcome Measure(s): Oocyte maturation and fertilization rates, embryonic developmental quality. Result(s): Significant differences were observed between TCM 199 and HTF regarding maturation rate (82% vs. 56.9%), fertilization rate (70% vs. 39.4%), and embryo quality (81.3% vs. 41.7%). Conclusion(S): Human tubal fluid medium, although widely used for embryo fertilization and maintenance in IVF techniques, is not,in appropriate medium for the maturation of oocytes obtained from PCOS patients in nonstimulated cycles.

Both a combined oral contraceptive and depot medroxyprogesterone acetate impair endothelial function in young women

Background: The study was conducted to determine whether the use of a combined oral contraceptive (COC) or depot medroxyprogesterone acetate (DMPA) interferes with endothelial function. Study Design: The study was conducted on 100 women between the ages of 18 and 30 years. Fifty women had not used hormonal contraception (control group) for at least 12 months, 25 were current users of a COC (ethinylestradiol 30 mcg+levonorgestrel 150 mcg) and 25 were current users of DMPA (150 mg) for at least a 6-month period. All women were evaluated for brachial flow-mediated dilation (FMD), intima-media thickness, carotid distensibility and stiffness index, arterial pressure, body mass index, waist circumference, heart rate and lipid profile. Results: A significant difference in FMD was observed between the COC and control groups (6.4 +/- 2.2% vs. 8,7 +/- 3.4%, p<.01) and between the DMPA and control groups (6.2 +/- 2.1% vs. 8.7 +/- 3.4%, p<.01). The DMPA group had lower values of total cholesterol (TC) and low-density lipoprotein (LDL-C) than COC users and the control group (TC: DMPA=139.9 +/- 21.5 mg/dL vs. controls=167.1 +/- 29.2 mg/dL vs. COC=168.2 +/- 37.5. p=.001; LDL-C: DMPA-85.3 +/- 20.1 mg/dL vs. controls=102 +/- 24.5 mg/dL vs. COC=106.7 +/- 33.3 mg/dL, p=.01). The control group had higher levels of high-density lipoprotein (HDL-C) than the DMPA and COC groups (controls=52.4 +/- 14.1 mg/dL vs. DMPA=42.2 +/- 7.2 mg/dL vs. COC=45.4 +/- 9.1 mg/dL, p=.001). No significant differences were observed regarding the other variables. Conclusions: FMD was lower among COC and DMPA users, Suggesting that these hormonal contraceptives may promote endothelial dysfunction. (C) 2009 Elsevier Inc. All rights reserved.

Serological testing for celiac disease in women with endometriosis. A pilot study

Purpose of Investigation: Celiac disease (CD) involves immunologically mediated intestinal damage with consequent micronutrient malabsorption and varied clinical manifestations, and there is a controversial association with infertility. The objective of the present study was to determine the presence of CD in a population of infertile women with endometriosis. Methods: A total of 120 women with a diagnosis of endometriosis confirmed by laparoscopy (study group) and 1,500 healthy female donors aged 18 to 45 years were tested for CD by the determination of IgA-transglutaminase antibody against human tissue transglutaminase (t-TGA) and anti-endomysium (anti-EMA) antibodies. Results: Nine of the 120 women in the study group were anti-tTGA positive and five of them were also anti-EMA positive. Four of these five patients were submitted to intestinal biopsy which revealed CD in three cases (2.5% prevalence). The overall CD prevalence among the population control group was 1:136 women (0.66%). Conclusion: This is the first study reporting the prevalence of CD among women with endometriosis, showing that CD is common in this population group (2.5%) and may be clinically relevant.

Primary adenocarcinoma of the fallopian tube as an incidental finding during surgery in a postmenopausal patient with unspecific pelvic pain

Primary fallopian tube carcinoma (PFTC) is a rare gynecologic neoplasm and is usually diagnosed late and presents classically with a,characteristic group of symptoms. We describe a case of a 76-year-old woman who underwent TVS requested by the family physician due to unspecific pelvic pain. An adnexal mass was found with morphology associated with high levels of CA125 suggestive of a malignant tumor. During laparotomy, a mass located in the left tube was found. Histopathology confirmed PFTC. Total hysterectomy, salpingo-oophorectomy and adjuvant chemotherapy with carboplatin/paclitaxel were performed. The patient has not yet presented any signs of recurrence.

Leuprolide acetate reduces both in vivo and in vitro ovarian steroidogenesis in infertile women undergoing assisted reproduction

Despite the probable inhibitory effects of GnRH analogues on ovarian steroidogenesis in vitro, their association with assisted reproduction protocols shows favorable results. This suggests that there are important differences in the behaviors of these drugs when administered in vivo versus in vitro. To clarify these differences, this study was designed to analyze the effect of leuprolide acetate (LA) on ovarian steroidogenesis in women undergoing In Vitro Fertilization (IVF). A prospective, randomized open label study was conducted on 14 women (26-35 years): seven receiving only gonadotrophins (Group 1) and seven receiving gonadotrophin plus LA at 1mg/day (Group 2). The LA in vivo effect was determined with serum and follicular fluid (FF) samples and via luteinized granulosa cell cultivation (GCC), where cells were obtained during oocyte retrieval after ovarian hyperstimulation. In vitro analysis was performed via addition of LA to GCC only for Group 1 (without LA) at progressively higher concentrations (0, 10(-12), 10(-9) and 10(-6) M). In vivo, the main observation was a reduction in androgen production in Group 2, represented by lower androstenedione production in FF (G1 = 6479 +/- 3458; G2 = 3021 +/- 1119 ng/ml; p = 0.04) and a lower testosterone peak in GC at 96 h (G1 = 0.64 +/- 0.12 ng/ml; G2 = 0.50 +/- 0.19ng/ml; P = 0.02), but a higher fertilization rate (G1 = 67%; G2 = 83%; p = 0.009). in vitro, testosterone, estradiol and progesterone were also reduced by LA, even though this reduction occurred for progesterone only at the highest LA dosage (10(-6) M; 606.0 +/- 114.3 ng/ml versus 1524.0 +/- 246.5 ng/ml; p=0.02). Results show that LA reduces ovarian steroidogenesis in vivo by essentially inhibiting androgen synthesis; whereas, in vitro, ovarian steroidogenesis is reduced overall. (C) 2008 Elsevier Inc.

Lipid peroxidation and vitamin E in serum and follicular fluid of infertile women with peritoneal endometriosis submitted to controlled ovarian hyperstimulation: a pilot study

Objective: To assess the level of lipid peroxidation (LP) and vitamin E in the follicular fluid and serum of infertile patients, with or without endometriosis. who were submitted to ovulation induction for assisted reproduction procedures. Design: Prospective study. Setting: Assisted conception unit, university hospital. Patient(s): Infertile patients 20 to 38 years of age were selected prospectively and consecutively and were divided into the endometriosis group (17 patients with pelvic endometriosis) and the control group (19 patients with previous tubal ligation or male factor and without endometriosis). Intervention(s): Peripheral blood samples were collected on D1 (before the beginning of the use of gonadotropins), D2 (day of hCG administration), and D3 (day of oocyte retrieval). On D3, follicular-fluid samples free from blood contamination also were collected and stored. Main Outcome Measure(S): Lipid peroxidation was assessed by malondialdehyde quantification by spectrophotometry, and measurement of vitamin E was performed by HLPC. Result(s): On D1, no significant difference in LP was observed between groups. However, vitamin E levels were significantly higher in the control group. On D2, LP levels were significantly higher in the endometriosis group compared with in the control group, and vitamin E levels continued to be significantly higher in the control group. On D3, there was no significant difference in serum and follicular-fluid levels of LP and vitamin E between groups. However, on D3, vitamin E levels were found to be significantly higher in serum than in follicular fluid in both groups, whereas malondialdchyde levels were significantly lower in follicular fluid than in serum only in the control group. Conclusion(s): Before the beginning of ovulation induction, a significant decrease in vitamin E was observed in patients with endometriosis, perhaps because antioxidants are consumed during oxidation reactions. After ovulation induction with exogenous gonadotropins, the group of patients with endometriosis not only presented increased lipid peroxidation but also maintained lower vitamin E levels than the control group, a fact that hypothetically could compromise oocyte quality in endometriotic patients. However, on the day of oocyte retrieval, both serum LP potential and vitamin E levels were found to be similar in the two groups. (Fertil Steril(R) 2008; 90:2080-5.

Ultrasonography in pregnant women with antiphospholipid syndrome using salicylic acid and heparin

The objective of the present study was to evaluate fetal biometry, Doppler values, and perinatal outcomes in pregnant women with antiphospholipid syndrome treated with acetylsalicylic acid and heparin. Twenty-five pregnant women with antiphospholipid syndrome using 100 mg/day acetylsalicylic acid and 5,000 IU heparin every 12 h were evaluated in this prospective observational study. Ultrasonography was performed between 24 and 38 weeks of gestational age to assess estimated fetal weight, placental thickness, amniotic fluid index, fetal biophysical profile and Doppler evaluation of maternal uterine arteries, and fetal middle cerebral and umbilical arteries. Data regarding Apgar score, gender, delivery mode, and birth weight and length were recorded after birth. The observed values for ultrasonographic assessment and perinatal outcomes were not very different from the expected values for normal pregnancies. The birth weight was 2863.3 +/- A 737.7 g (mean +/- A SD) and length was 46.8 +/- A 4.2 cm. Only one newborn (4%) had the 1-min Apgar score < 7 and all had the 5-min Apgar score > 7. Gestational and perinatal evaluation of pregnant women with antiphospholipid syndrome using both acetylsalicylic acid and heparin was reassuring.
