Identification of vaginal microbiome associated with IVF pregnancy.

The factors that cause a preterm birth (PTB) are not completely understood up to date. Moreover, PTB is more common in pregnancies achieved by in-vitro fertilization (IVF) than in spontaneous pregnancies. Our aim was to compare the composition of vaginal microbiome at 12 weeks of gestation between women who conceived naturally or through IVF in order to study whether IVF PTB-risk could be related to vaginal microbiome composition. We performed an observational, prospective and multicentre study among two public hospitals and a fertility private clinic in Spain. Vaginal swabs from 64 pregnant women at 12 weeks of gestation were collected to analyse the microbiome composition by sequencing the V3-V4 region of the 16S rRNA. Our results showed that the vaginal microbiome signature at 12 weeks of pregnancy was different from women who conceived naturally or through IVF. The beta diversity and the genus composition were different between both cohorts. Gardnerella, Neisseria, Prevotella, and Staphylococcus genus were enriched genus in the vaginal microbiome from the IVF group, allowing us to create a balance model to predict both cohorts. Moreover, at species level the L. iners abundance was higher and L. gasseri was lower in the IVF group. As a conclusion, our findings were consistent with a proposed framework in which IVF pregnancy are related to risk for preterm birth (PTB) suggesting vaginal microbiome could be the reason to the relation between IVF pregnancy and risk for PTB.

Position of the Spanish Menopause Society regarding the management of perimenopause.

Perimenopause is an imprecise period in woman over 40 years of age, which comprises the time between the moment that the first changes in the menstrual cycle appear and the year following the definitive cessation of the menses. Besides irregular bleeding, many women also complain of hot flashes and other characteristic symptoms of postmenopause. Moreover, most of them are concerned about the future impact that these events may have on their health, such as needing health exams or continuing to use contraceptive methods. A panel of experts from the Spanish Menopause Society has met to establish diagnostic and therapeutic guidelines for this period based on the best available evidence.

Estrogen-related genes and postmenopausal osteoporosis risk.

BACKGROUND: To date, more than 150 candidate genes related to osteoporosis have been described, but osteoporosis has increasingly been considered a polygenic disease modulated by environmental factors. It is thought that osteoporosis predisposition, pathology, and treatment response depend on the interaction between different genes or between genes and environmental factors. OBJECTIVE: The aim of this study was to evaluate the relationship between the presence of single nucleotide polymorphisms (SNPs) in the estrogen metabolic pathway and the development of osteoporosis and to determine whether this relationship is monogenic or whether interactions between genes exist. MATERIALS AND METHODS: A multicentric study with 1980 postmenopausal Spanish women in five Spanish communities was conducted. The women completed a specific questionnaire that inquired about risk factors for osteoporosis. Data on participants' bone mineral density were obtained with dual-energy X-ray densitometers, and genetic data were obtained from frozen peripheral blood. RESULTS: The digenic protection combinations indicated involvement of the wild-type genotype (WT) of the 3'UTR marker for the CYP19A1 gene, the IVS4 marker of the same gene, and the BMP15 and FSHR genes. Among patients who carried two or more of the genotypes considered 'risky', the triple combination among markers of the ESR2 and NRIP1 genes with any of the two mutations of the analyzed markers of the BMP15 gene gave a mean T-score value of -2.32±0.91 (p = 0.02). CONCLUSION: Variants of the new candidate genes (NRIP and BMP15) can predispose patients to osteoporosis.

Cervicovaginal agenesis: spontaneous gestation at term after previous reimplantation of the uterine corpus in a neovagina: Case Report.

We present an exceptional case of a patient with complete cervical atresia and total vaginal aplasia. After McIndoe vaginoplasty, cervicoitsmic resection with implantation and reimplantation of the uterine corpus in the neovagina, and conservative surgery for endometriosis, the patient had normal menstruations and became pregnant spontaneously. A Caesarean section was performed at week 36. This is the third published case report of a successful spontaneous pregnancy and Caesarean section at term in a patient with complete cervicovaginal aplasia, and the first published case study of a patient becoming pregnant after McIndoe vaginoplasty, cervicoistmic resection and utero-neovaginal anastomosis. Gestation developed successfully without cerclage. We recommend conservative surgery in patients with congenital cervical atresia. McIndoe vaginoplasty should be performed as soon as possible in adolescence if there is associated vaginal aplasia. Nevertheless, fibrotic stenosis can occur, even after several years and, therefore, additional operations and uterine reimplantation may be required.

Stress symptoms and burnout in obstetric and gynaecology residents.

OBJECTIVE: This study was designed to examine the burnout syndrome among residents in obstetrics and gynaecology in Spain, and to analyse the predisposing factors for this condition. SETTING: Eight Spanish University hospitals. SAMPLE: A total of 162 residents representative of all active residents in obstetrics and gynaecology in Spain with regards to age, sex and year of residency were asked to take part in this survey. METHODS: The Maslach Burnout Inventory was mailed to each resident of eight Spanish hospitals representative of all active residents in obstetrics and gynaecology in Spain with regards to age, sex and year of residency. Burnout was defined as a high score on the emotional exhaustion or depersonalisation subscores, according to validated standard cutoff values. The demographic and predisposing work factors were noted for each participant using a self-reported questionnaire. A binary logistic regression model was constructed from all predisposing factors as covariates for the prediction of the burnout syndrome. RESULTS: Sixty-seven percent of the 162 eligible residents returned their questionnaires within a 3-month period. Of those, 58% fulfilled the criteria for the burnout syndrome. In the multivariate analysis, marital status and workload in office practice were found to be significant predisposing factors. Single marital status increased the odds ratio for burnout by 5.2 (95% CI 1.3-21). For every extra ten patients attended in the office per week, the odds ratio for burnout increased by 1.25 (95% CI 1.0-1.5). A stratified multivariate subanalysis showed that this risk remained significant only in the group of residents without staff supervision with an odds ratio of 2.1 (95% CI 1.3-2.9). CONCLUSION: The prevalence of the burnout syndrome during obstetrics and gynaecology residency is high. Single marital status and workload in office practice without staff supervision are significant predisposing factors.

The dilemma of menopause and hormone replacement--a challenge for women and health-care providers: knowledge of menopause and hormone therapy in Spanish menopausal women.

BACKGROUND: An important goal in menopause research is to develop knowledge and identify interventions that strive to promote, maintain and enhance well-being for women. OBJECTIVE: To evaluate the knowledge of postmenopausal Spanish women about menopause and their knowledge of and trust in hormone replacement therapy (HRT) and to identify their sources of information and how those data are related to compliance with their prescription. STUDY DESIGN: A total of 270 symptomatic postmenopausal women were personally interviewed using a structured questionnaire, which was designed to collect information on their familiarity with medical menopause studies, the menopause and the effects of HRT, their knowledge of alternative therapies, and to identify their sources of information. RESULTS: The most well-known menopausal complaints were hot flushes, sweats, irregular menstruation, cessation of menstruation, irritability and mood changes. Following suggestions of other symptoms by the interviewer, other complaints such as vaginal dryness, insomnia and depression/anxiety were also mentioned. HRT and phytoestrogens were recognized as treatments for the climacteric by most of the women. A woman's decision to seek treatment was initiated in 77% of cases by the gynecologist, in 12% by the general practitioner, in 3% by friends/family and in 3% by books/magazines. The most frequent responses of women to the onset of menopausal symptoms were to talk with their partner (39%), to discuss it with their gynecologist (33%) or with their general practitioner (14%) and to talk with their friends/family or to read books/magazines (10%). CONCLUSIONS: Vasomotor symptoms are recognized as the main complaint during the climacteric and HRT and phytoestrogens as the main therapies. Gynecologists play an important role in assuring compliance with therapies related to the menopause.

Prophylactic approach for asymptomatic post-menopausal women: osteoporosis.

To consider what a correct preventive approach for osteoporosis should be in the management of the asymptomatic post-menopausal woman. Literature review and opinions on this issue shared by a group of professionals with wide clinical experience in health care for peri- and post-menopausal women. There is agreement that osteoporosis combines most of the ideal requirements for the application of a preventive strategy. The natural evolution of this pathology leads to serious events, fractures, but it provides various opportunities for prevention. Osteoporosis can be avoided and in particular, fractures due to bone fragility and their consequences should be avoided. Nowadays, there are different courses of action (pharmacological or otherwise) with proven effectiveness for the prevention osteoporosis and osteoporotic fractures. However, long-term action is required for a broad segment of the population, so a certain strategy is necessary to guide clinical decisions for different profiles of women. There is little data in the literature to justify a different preventive approach, depending on the presence or absence of vasomotor symptoms, but clinical experience shows that their absence is not associated with a lower osteoporosis risk. Different strategies have been tried for the prevention of osteoporosis and its complications and some of them might be effective, but there is no analysis with conclusive results. A preventive strategy for osteoporosis should be included in the management of asymptomatic post-menopausal women, because this is an avoidable pathology and the absence of vasomotor symptoms does not reduce the risk of its development. Nevertheless, a well-designed cost-benefit analysis is needed to justify the implementation of any strategy at a community level, because adverse effects and economic cost could exceed the benefits obtained in low fracture risk populations.

Relevance of the results of the Women's Health Initiative on the prescription of hormone therapy in Spain.

OBJECTIVE: To identify the possible repercussions of suspending the estrogen-gestagen arm of the WHI trial among Spanish health-care professionals habitually using hormonal therapy in their practice of medicine and to attempt to identify the possible changes in their attitudes and prescription habits regarding this issue. DESIGN: We designed a survey in the form of an anonymous self-administered interview with 18 questions, distributed to 3592 specialists in Obstetrics and Gynecology belonging to the Spanish Association for the Study of the Menopause (AEEM in its Spanish acronym) and the Spanish Gynecology and Obstetrics Society (SEGO in its Spanish acronym). The study was national in scope and the questionnaires were distributed between November 2002 and January 2003, with reception of questionnaires concluding in February 2003. RESULTS: Of the participants, 96% stated that they knew the results of the Women's Health Initiative (WHI) study as published in the Journal of the American Medical Association; 63% felt that the cardiovascular results of the trial were important for their clinical practice (55% of males and 80% of females surveyed), and 42% of the men and 18% of women stated the opposite. The results of the WHI should not be extrapolated to other types of hormone therapy (84%) and only 10% considered this possibility acceptable. CONCLUSIONS: From our study, it can be inferred that Spanish gynecologists believe they know the WHI study and state that its results cannot be extrapolated to our setting. However, following its publication, they have suspended more than 10% of therapies, have limited their indications, and have reduced their recommended duration.

Efficacy and safety of a phytoestrogen preparation derived from Glycine max (L.) Merr in climacteric symptomatology: a multicentric, open, prospective and non-randomized trial.

A multicentric, open, prospective, observational and no-randomized clinical trial was carried out in Spain with 190 postmenopausal women receiving a soy preparation rich in isoflavones (PHYTO SOYA, capsules containing 17.5 mg isoflavones). The main object of the present study was to investigate its efficacy in alleviating the symptomatology derived from the lack of estrogen, mainly hot flushes, but also other symptoms such as sleep disorder, anxiety, depression, vaginal dryness, loss of libido and bone pain. Each patient received 35 mg isoflavones per day in two doses. During the four months' treatment, a statistically significant decrease in the number of hot flushes with PHYTO SOYA was experienced by 80.82% women; only 5,48% patients did not improve with the treatment. The average reduction was 47.8%, which is equivalent to 4 hot flushes. All the other studied parameters also showed a statistically significant decrease. No severe side-effects were reported and tolerance was excellent. Treatment with PHYTO SOYA resulted in a significant improvement of the symptomatology that accompanies the lack of estrogen during menopause.

Insulin, androgens, and obesity in women with and without polycystic ovary syndrome: a heterogeneous group of disorders.

OBJECTIVE: To analyze the correlations among insulin, androgens, body mass index (BMI), and other related metabolic anomalies in women with and without polycystic ovary syndrome (PCOS). DESIGN: Retrospective study of normal and obese women with and without PCOS. SETTING: Gynecologic endocrinology units of Elche, San Juan, and Alicante Hospitals and Hormone Laboratory at Alicante University Hospital ("Miguel Hernández" University). PATIENT(S): A total of 212 women were studied: 137 with PCOS and 75 without PCOS. INTERVENTION(S): BMI, gonadotropins, insulin, androgens (T, androstenedione, DHEAS), 17alpha-hydroxyprogesterone, sex hormone-binding globulin, and triglycerides were studied. Glycemia and insulin response to the tolerance test (GTT) with a 100-g oral glucose load were also assessed in 103 women. RESULT(S): A good correlation between insulin and BMI was found in normal and obese women without hormonal dysfunction and in patients with or without PCOS. Good correlations, although lower, between insulin and T, and BMI, insulin, and T with triglycerides were also found in patients with PCOS. These patients fell into clearly distinct categories: with or without insulin resistance and with or without obesity, but slim women with PCOS had insulin and metabolic variables similar to those without PCOS, and most obese women with PCOS were insulin-resistant and more hyperandrogenic and hypertriglyceridemic. CONCLUSION(S): Insulin, androgens, and BMI are related in women both with PCOS and without PCOS, especially in obese ones. Insulin and metabolic indices are similar in lean women with PCOS and those without PCOS, but obese women with PCOS are more insulin-resistant, hyperandrogenic, and hypertriglyceridemic. Three types of disorders can be distinguished: simple nonhyperandrogenic obesity, typical nonhyperinsulinemic PCOS, and insulin-resistant PCOS.

Intraperitoneal and subcutaneous treatment of experimental endometriosis with recombinant human interferon-alpha-2b in a murine model.

OBJECTIVE: To determine the effect of human interferon (IFN)-alpha-2b on experimental endometriosis in rats. DESIGN: Experimental, controlled, double-blind randomized study. SETTING: Experimental surgery laboratory in a university department. ANIMAL(S): Ninety-six Wistar rats with endometriosis, induced by transplanting four endometrial fragments into the peritoneal cavity. INTERVENTION(S): One third of the animals served as controls (group A). The others were randomly divided into two groups and were given IFN-alpha-2b either as a single intraperitoneal dose (group B) or as three SC doses (on alternate days) (group C). MAIN OUTCOME MEASURE(S): Laparotomy was performed to measure the size of each implant at various times (days 0, 6, 12, 20, and 120 after treatment). RESULT(S): There were no differences among the groups in the size of the average implants before IFN was administered (17.3+/-6.7, 19.7+/-7.8, and 18.1+/-9.2 mm for groups A, B, and C, respectively). These values were significantly smaller after treatment in group B (14.9+/-8.0 mm) and group C (14.0+/-9.5 mm) than in the control group (17.6+/-7.5 mm) (P<.05). Intraperitoneal IFN produced an initial maximum decrease in the size of the implants (40% reduction on day 6), which diminished until day 20 (20%) and then was maintained on a plateau until day 120 (25%). By contrast, group C showed an initial minimal reduction (13% at day 6), which increased up to day 20 (19%), after which a plateau was reached (23% at day 120). Thus, the effects in both treatment groups were similar in the long term. CONCLUSION(S): Two short regimens of human IFN-alpha-2b reduced the size of experimental endometriosis in rats.

Benign intracardiac teratoma detected prenatally. Case report and review of the literature.

Primary cardiac tumors are rare and, until recently, were mostly incidental postmortem findings. Nowadays, due to the widespread use of prenatal ultrasound scans, we are able to diagnose them in utero. We present a case of an intracardiac teratoma diagnosed at 38 weeks, menstrual age. Previous scans had been normal. Labor was induced, and a female infant with an Apgar score of 9 and 4, at 1 and 5 min, was delivered. Her condition worsened rapidly. She died 16 h after birth. Necropsy was performed, and a cystic, mature teratoma of 4 cm was found in the interventricular septum, growing into the right ventricle. No other anomalies were found. This probably represents the first case of an intracardiac, benign teratoma diagnosed prenatally.

Individual and combined effects of triptoreline and gestrinone on experimental endometriosis in rats.

OBJECTIVES: To evaluate the effects of triptoreline, gestrinone, and both, on experimental endometriosis in rats. STUDY DESIGN: Experimental endometriosis was surgically induced in 225 Wistar rats. Of these, 202 rats showed at least one grown implant, 22 of which composed the control group, while 180 were treated with triptoreline, gestrinone, or both, for 28 days. The implants were evaluated again after 25 days. RESULTS: There were no changes in size in the control group. About 73% of the implants treated with triptoreline showed a high reduction (> 50%), vs. 51% with gestrinone (P < 0.0005) and 65% with both (P < 0.005). Triptoreline caused macroscopic resolution in 40% of the implants vs. 31% for gestrinone (not significant) and 26% for both substances (P < 0.05). In the triptoreline group, the mean size of the implants decreased by 65% between the 25th and 28th days, 58% between the 29th and the 35th, and 39% after the 36th day. This reduction was 51%, 36%, and 33%, respectively, in gestrinone group. CONCLUSIONS: Triptoreline was more effective than gestrinone, but perhaps not in the long run. Their association did not improve the results.

Hyperreactio luteinalis: intraoperative finding during a cesarean section in a twin pregnancy.

Bilateral ovarian enlargement can be found in the course of a cesarean section. It is necessary to keep in mind that hyperreactio luteinalis is a benign condition, because the appropriate management is conservative. We present an unexpected, intraoperatively diagnosed case of bilateral ovarian cystic-solid tumours (13 cm) in a twin pregnancy.

Abdominal myomectomy: results of a simple operative technique.

OBJECTIVES: To report a simple and safe procedure of abdominal myomectomy and our results performing this technique. DESIGN: The operative technique comprises the incision on the most prominent part of the myoma, the use of a hooked clamp to hold the tumor, and a surgical knife to peel it, without removing the apparent excess of myometrium or serosa. SETTING: University Medical Centers and private practice. PATIENTS: Eighty patients, 9 of whom were operated between 10 and 26 weeks of pregnancy, 3 during cesarean section, and 22 others who had infertility. RESULTS: Myomectomy was performed successfully in all patients for whom it was scheduled. Eight of nine pregnant patients had successful deliveries at term. The cumulative 10-year reoccurrence and reoperation rates of life-table analysis were 38% and 18%, respectively. The cumulative conception rates were 100% for otherwise unexplained infertility at 2 years, and 63% and 79% at 5 years for all infertile and all patients attempting conception after myomectomy, respectively. An age > 30 years, infertility > 3 years, and multiple fibroids negatively affected these rates, whereas the use of an absorbable adhesion barrier (Interceed; Johnson & Johnson AB, Somerville, NJ) had a positive effect. CONCLUSIONS: This procedure is an appropriate alternative for most women who want to preserve or enhance fertility potential, and if necessary, for pregnant women.
