RESUMO

BACKGROUND: This randomized, multicenter, open-label clinical trial was intended to generate pilot data on the efficacy and safety of the gonadotropin-releasing hormone agonist (GnRHa) deslorelin (D) with low-dose estradiol ± testosterone (E2 ± T) add-back for endometriosis-related pelvic pain. METHODS: Women with pelvic pain and laparoscopically confirmed endometriosis were treated with a six-month course of daily intranasal D with concurrent administration of either transdermal E2, intranasal E2, or intranasal E2 + T. Efficacy data included evaluation of dyspareunia, dysmenorrhea, pelvic pain, tenderness, and induration. Cognition and quality of life were also assessed. Safety parameters included assessment of endometrial hyperplasia, bone mineral density (BMD), and hot flashes. RESULTS: Endometriosis symptoms and signs scores decreased in all treatment arms from a baseline average of 7.4 to 2.5 after 3 months of treatment and 3.4 after 6 months. BMD changes and incidence of hot flashes were minimal, and no endometrial hyperplasia was observed. Patient-reported outcomes showed significant improvement across multiple domains. CONCLUSIONS: Daily intranasal D with low dose E2 ± T add-back resulted in significant reduction in severity of endometriosis symptoms and signs with few safety signals and minimal hypoestrogenic symptoms that would be expected with the use of a GnRHa alone.

RESUMO

OBJECTIVE: To identify high-risk categories for high-order multiple pregnancy (HMP) in in vitro fertilization (IVF), establish clinic-specific HMP risk data for counseling use, and verify their utility in reducing HMP. DESIGN: Before and after intervention study. SETTING: Two IVF programs using the same embryology laboratory and IVF protocols. PATIENT(S): All IVF patients undergoing fresh embryo transfers. INTERVENTION(S): Use of clinic-specific age, diagnosis, and embryo score (ES) risk data in assessing individual HMP risk during informed consent. MAIN OUTCOME MEASURE(S): HMP and pregnancy outcomes. RESULT(S): In determining clinic-specific high risk categories and developing outcomes-based HMP risk data for counseling, the good outcome rate (GR) was defined as the percentage of singleton or twin deliveries per cycle and the bad outcome rate included no pregnancy or nondelivered pregnancies (miscarriages, multifetal reduction) and HMP per cycle. During 1995 to 1999, age <35 years, calculated morphologic ES, and donor egg (DE) cycles were factors shown by logistic regression to statistically significantly affect the GR. The optimal GRs for DE <35 and >or=35 years (donor age), and non-DE cycles <35 years were achieved with two (57.7%), three (43.2%), and three (43.2%) embryos transferred, respectively. A DE <35 years with >or=3 embryos transferred had the highest risk for HMP. The GR correlated (0.91) with the ES according to the formula: GR = 3.3 + 2.0 ES, when ES range was between 4 and 26. Clinic-specific risks for HMP based on age, diagnosis, and ES were developed and considered while counseling for ET during 2004. The clinic-specific HMP risk data made for a reduction in the HMP rate of 90.9% for DE-IVF (11.8% to 1%) and 53.8% for all IVF (9.1% to 4.2%), without decreases in clinical pregnancy or delivery rates. Physicians showing the greatest decline (64%) in HMP had no reduction in pregnancy or delivery rates. CONCLUSION(S): The use of clinic-specific HMP risk data in counseling based on age, diagnosis, and ES provided a 53% to 64% reduction in HMP without affecting rates of pregnancy or delivery. The clinic-specific ES system correlated closely with good outcomes. A standardized ES system may provide useful information for counseling during ET informed consent.

RESUMO

OBJECTIVE: The aim of this study was to investigate the effect of parental age as a factor in the observed decline in the male to female birth ratio expressed as the offspring sex ratio (OSR). STUDY DESIGN: A prospective multicenter study was conducted from August 2005 to February 2007 at five community-based hospitals in Osaka, Japan. Pregnant women in the first trimester were recruited at their first prenatal care visit and followed until delivery. Multiple pregnancies and assisted conceptions were excluded. Periconceptional parental ages were recorded. Neonatal information was obtained at the time of delivery. Proportional distribution of categorical variables was studied using the chi(2) or Fisher's exact tests (two-tailed). RESULTS: Data on 3,049 deliveries were available for review. OSR for the largest paternal and maternal subgroup (both, age 30-34) were male dominant (1.17 and 1.12, respectively). Paternal age > or =40 showed a smaller OSR (0.75 vs 1.17, P = 0.001). Advanced maternal age was associated with smaller OSR: age 35-39, 0.87 versus 1.12, P = 0.02; and age > or =40, 0.63 versus 1.12, P = 0.047. Synergistic effects of increasing paternal and maternal age on the OSR were observed. OSR for parental ages > or =40 were significantly smaller than ages 30-34 (0.52 vs 1.17, P = 0.029). CONCLUSIONS: Increasing paternal ages synergistically decrease the male to female birth ratio.

RESUMO

Vascular smooth muscle cell (VSMC) migration is a pivotal early step in blood vessel remodeling; however, very little is known about the regulation of this process in the human endometrium during the menstrual cycle. In this study, explants of human endometrium were incubated with estradiol and/or progesterone and the conditioned medium (CM) applied to cultures of VSMC to test the hypothesis that estrogen and progesterone stimulate endometrial cells to secrete a factor(s) that promotes VSMC migration. Endometrial explants were composed of highly organized glands and stroma. VSMC migration (cells migrated in 21 h/mm(2) fibronectin-coated semipermeable membrane) in the presence of CM from human endometrial explants obtained in the proliferative phase of the menstrual cycle and incubated for 24 h with estradiol was approximately threefold greater (P < 0.001) than with medium alone and greater (P < 0.05) than with CM from explants treated with estradiol plus progesterone or progesterone. It is concluded, therefore, that estrogen stimulates endometrial secretion of a factor(s) that promotes VSMC migration as an early step in vessel remodeling within the endometrium.

RESUMO

OBJECTIVE: To evaluate whether acupuncture improves rates of pregnancy and live birth when used as an adjuvant treatment to embryo transfer in women undergoing in vitro fertilisation. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Medline, Cochrane Central, Embase, Chinese Biomedical Database, hand searched abstracts, and reference lists. Review methods Eligible studies were randomised controlled trials that compared needle acupuncture administered within one day of embryo transfer with sham acupuncture or no adjuvant treatment, with reported outcomes of at least one of clinical pregnancy, ongoing pregnancy, or live birth. Two reviewers independently agreed on eligibility; assessed methodological quality; and extracted outcome data. For all trials, investigators contributed additional data not included in the original publication (such as live births). Meta-analyses included all randomised patients. DATA SYNTHESIS: Seven trials with 1366 women undergoing in vitro fertilisation were included in the meta-analyses. There was little clinical heterogeneity. Trials with sham acupuncture and no adjuvant treatment as controls were pooled for the primary analysis. Complementing the embryo transfer process with acupuncture was associated with significant and clinically relevant improvements in clinical pregnancy (odds ratio 1.65, 95% confidence interval 1.27 to 2.14; number needed to treat (NNT) 10 (7 to 17); seven trials), ongoing pregnancy (1.87, 1.40 to 2.49; NNT 9 (6 to 15); five trials), and live birth (1.91, 1.39 to 2.64; NNT 9 (6 to 17); four trials). Because we were unable to obtain outcome data on live births for three of the included trials, the pooled odds ratio for clinical pregnancy more accurately represents the true combined effect from these trials rather than the odds ratio for live birth. The results were robust to sensitivity analyses on study validity variables. A prespecified subgroup analysis restricted to the three trials with the higher rates of clinical pregnancy in the control group, however, suggested a smaller non-significant benefit of acupuncture (odds ratio 1.24, 0.86 to 1.77). CONCLUSIONS: Current preliminary evidence suggests that acupuncture given with embryo transfer improves rates of pregnancy and live birth among women undergoing in vitro fertilisation.

RESUMO

A growing body of information suggests antigonadotropic and atretogenic roles for granulosa cell-derived insulin-like growth factor binding proteins (IGFBPs) 4 and 5 during ovarian folliculogenesis. Activation of protein kinase-A (PKA) in rat granulosa cells has been shown to modulate the relative expression of IGFBP-4 and -5 transcripts and proteins. In this article, we assess the role of protein kinase-C (PKC) in this regard. Provision of granulosa cells with phorbol 12-myristate 13-acetate (PMA) (but not 4alphaPMA, an inert analogue), a tumor-promoting phorbol ester and an established activator of PKC, was without significant effect on the expression of IGFBP-4 transcripts but resulted in biphasic dose-dependent alterations in IGFBP-5 transcripts and in the accumulation of the IGFBP-4 and -5 proteins. Comparable effects were noted for GnRH, an established PKC agonist. Provision of staurosporine, a potent inhibitor of the catalytic subunit of PKC, produced significant dose-dependent decrements in the relative expression of IGFBP-5 transcripts. Treatment with FSH (presumptively PKA-mediated) markedly attenuated the ability of PMA or GnRH to upregulate the accumulation of the IGFBP-5 (but not IGFBP-4) protein. Taken together, our present findings indicate that the modulation of rat ovarian IGFBP-4 and -5 is PKC as well as PKA dependent and that these two signaling pathways interact in a diametrically opposed and antagonistic fashion.
