RESUMO

PURPOSE: Protein C global assay tests the global function of the protein C pathway, the most clinically significant anticoagulant pathway in humans. The objective of this study is to assess the difference in protein C global assay levels, throughout twin gestation, in naturally conceiving and ART-treated women. METHODS: This is a prospective cohort longitudinal study of pregnant women with twin gestation. Protein C Global evaluation was performed on frozen blood samples. Ninety-eight women with twin pregnancy, thirty-eight naturally conceived and sixty following ART, were evaluated on four occasions: during the first, second, and third trimesters, and 6 weeks or later after delivery (baseline). RESULTS: Protein C global assay levels were lower throughout pregnancy as compared to basal levels in both the naturally conceived and ART-conceived groups. However, protein C global assay levels were similar between the ART-conceived and naturally conceived twin pregnancies in all three trimesters. Perinatal complications were associated with decreased protein C global assay levels during the third trimester, although no difference was encountered between naturally conceived and ART-complicated twin pregnancies. CONCLUSION: While protein C global assay levels drop during twin pregnancy, there is no difference between ART-conceived and naturally conceived gestations. Decreased levels of protein C global assay during the third trimester were similarly associated with perinatal complications in both groups. Our results imply that twin pregnancy of itself is a more dominant factor for perinatal complications as compared to other factors, such as subfertility or the exposure to ART per se.

RESUMO

BACKGROUND AND OBJECTIVES: Vaginal pixelated low power and long pulses (LPLP) CO2 laser has been suggested as an optional treatment for stress urinary incontinence (SUI) with many studies reporting short-term improvements. The objective of this study was to assess the 1-year subjective and objective efficacy of vaginal CO2 laser in women with urodynamic SUI. STUDY DESIGN/MATERIALS AND METHODS: This was a prospective multicenter study. Patients with confirmed urodynamic SUI graded as mild or moderate were included. We used three sessions of fractional pixelated CO2 laser for vaginal application and followed up the patients at 6 and 12 months. We used the following measures at follow-up: 1-hour pad test (ICS protocol), questionnaires including Pelvic Floor Distress Inventory 20 (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ), Patient Global Impression of Improvement (PGI-I), and a 3-day urinary diary. The urodynamic assessment was repeated at 6 months. RESULTS: Fifty-two patients with SUI had three laser treatments, of whom 48 completed a 6-month follow-up and 42 patients completed 12-month follow-up. No serious adverse events were recorded during the study period. A significant reduction on the 1-hour pad test was found from baseline (6.3 ± 1.6 g) to the 12-month follow-up (3.7 ± 1.4 g, P < 0.05) was found. PGI-I showed 75.0%, 61.9%, and 64.3% improvements at 3, 6, and 12 months, respectively. PFDI improved significantly and consistently from baseline until 12 months (37.2 ± 3.89 to 16.1 ± 3.7, P < 0.05). Similarly, PFIQ showed significant improvements from the first treatment up to 12 months. Urodynamic assessment at 6 months showed that 41.4% of patients had no stress incontinence. CONCLUSION: The vaginal CO2 laser was found to be effective for mild-to-moderate SUI over a follow-up period of 1 year, according to a variety of objective and subjective parameters. The wide range of parameters enables optimal patient consultation and subsequent treatment. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

RESUMO

BACKGROUND: Mycoplasma and Ureaplasma have been extensively studied for their possible impact on pregnancy, and their involvement in newborn diseases. This work examined Mycoplasma and Ureaplasma carriage among gravidas women and newborns in Israel, as well as associations between carriage and demographic characteristics, risk factors, pregnancy outcomes, and newborn morbidity rates. METHODS: A total of 214 gravidas women were examined for vaginal pathogen carriage through standard culture and polymerase chain reaction assay. Pharyngeal swabs were collected from newborns of carrier mothers. Clinical and demographic data were collected and infected newborn mortality was monitored for 6 months. RESULTS: Nineteen mothers were carriers, with highest prevalence among younger women. Pathogen carriage rates were 2.32% for Mycoplasma genitalium (Mg), 4.19% for Ureaplasma parvum (Up) and 2.32% for Ureaplasma urealyticum (Uu). Arab ethnicity was a statistically significant risk factor (p = 0.002). A higher prevalence was seen among women residing in cities as compared to villages. Thirteen (68%) newborns born to carrier mothers were carriers as well, with a higher prevalence among newborns of women delivering for the first time, compared to women that had delivered before. Infection rates among newborns were 20% for Mg (p = 0.238), 100% for Up (p < 0.01), and 28.5% for Uu (p = 0.058), with more male than female newborns being infected. No association was found between maternal carriage and newborn morbidity. CONCLUSIONS: Maternal Mycoplasma or Ureaplasma carriage may be associated with ethnicity and settlement type. Further studies will be needed to identify factors underlying these associations and their implications on delivery.

RESUMO

OBJECTIVE: To evaluate the outcome of twin pregnancies that were complicated by rupture of membranes at 13-20 weeks of gestation and were managed by expectant management or by selective termination. METHODS: A retrospective cohort study of all bichorionic twin pregnancies that were referred to three fetal medicine units between 2001 and 2016, due to rupture of membranes of one sac at 13-20 weeks of gestation. Women without clinical signs of infection who opted for expectant management or selective termination were included. RESULTS: 20 patients met the inclusion criteria. 7 of them were managed expectantly and 13 underwent selective termination. In the expectant management group there was one case of fetal demise and two cases of neonatal death, resulting in a survival rate of 79 %. The median gestational age at delivery was 30 weeks. 3 neonates suffered from prematurity-related complications and 2 suffered from oligohydramnios-related orthopedic complications. Following selective termination the survival rate was 50 % (all fetuses that were not reduced), the median gestational age at delivery was 39 weeks, and the neonatal outcome was favorable. The maternal outcome was favorable in both groups. CONCLUSION: Selective termination in twin pregnancies complicated by rupture of membranes at 13-20 weeks has a favorable outcome and should be offered.

RESUMO

OBJECTIVES: Guidelines recommend antibiotic treatment for every episode of asymptomatic bacteriuria throughout pregnancy in order to reduce maternal and fetal complications. We evaluated intra- and post-partum, as well as puerperal maternal and neonatal outcomes of an untreated group of pregnant women with asymptomatic bacteriuria at term. METHODS: This was a single center prospective cohort study. We enrolled women who came for labor or checkups, 37-42 weeks gestation, with singleton, vertex presentation. On admission, women gave a urine sample; we compared maternal, obstetric and neonatal data from the positive culture group to the negative culture. RESULTS: Among 248 pregnant women recruited, 205 negative and 32 positive urine cultures were collected. None of the women that participated in this study developed pyelonephritis during hospitalization or during the puerperium. No significant differences were detected between the two groups in terms of age, nulliparity, gestational age at delivery, length of hospitalization, birth type, intra- or post-partum fever, antibiotic treatment during labor or post-partum. CONCLUSIONS: No increased maternal or neonatal adverse effects were observed in women with untreated ASB detected at term.

RESUMO

The pathophysiology of the genuine empty follicle syndrome (EFS) is still debated. Ovarian aging has been contested as a cause of this condition. Our aim was to investigate the occurrence of the genuine EFS in cases of a low number of mature follicles in a prospective manner. Ninety-five infertile women were recruited and evaluated following conventional controlled ovarian stimulation (COS) with ≤ six follicles of ≥14 mm diameter on the day of hCG administration. Enrolled women were 37.5 ± 5.2 years of age with basal FSH level of 9.1 ± 3.7 mIU/L, antral follicle count (AFC) of 6.9 ± 4.6, and number of ≥14 mm follicles (on the day of hCG) of 3.4 ± 1.5. Among the 95 women, four were complicated by the genuine EFS (4.2%) with features of the depleted ovarian reserve. Comparison between these four cases and the 91 controls revealed significant differences between age, AFC, number of ≥14 mm follicles, and serum E2 level corresponding to 41.8 ± 1.7 versus 37.4 ± 5.2 years, 1.7 ± 0.6 versus 7.1 ± 4.5, 2.0 ± 0.8 versus 3.4 ± 1.5 follicles, and 356 ± 200 versus 975 ± 557 pg/mL, respectively. Post hoc analysis revealed that 56 among the 95 women fulfilled the Bologna criteria for poor ovarian response and all four cases matched the definition of the genuine EFS raising its incidence to 7.1% in this group. A logistic regression analysis showed that AFC was a significant factor in the development of the genuine EFS. We conclude that the genuine EFS complicates infertile women characterized by a low number of mature follicles. Our findings suggest that the mechanism behind this occurrence is associated with a more exhausted ovarian reserve.

RESUMO

OBJECTIVE: The cornerstone of concerns over trial of labor after cesarean (TOLAC) is the risk of uterine rupture. The purpose of this study was to document the rate of uterine rupture during TOLAC and to delineate its severity and consequences. MATERIALS AND METHODS: We retrospectively collected the data on vaginal and cesarean deliveries after a previous cesarean section with specific emphasis on uterine rupture and dehiscence in our center from 2006 through 2013. RESULTS: 22,670 deliveries were registered, with 18.2% rate of cesarean section. 2890 women had a single cesarean scar; of them 1206 delivered vaginally and 194 were re-operated during unsuccessful TOLAC. Seven cases of uterine rupture and 16 cases of dehiscence were recorded. There were no maternal, intrapartum or neonatal deaths, and no cesarean hysterectomy. There was one re-laparotomy, one ICU admission, and one blood transfusion; one neonate was admitted to NICU. TOLAC was successful in 86.1% of cases. CONCLUSIONS: Cautious selection and close monitoring of candidates are the cornerstones of successful management of TOLAC. Readily available facilities for emergency cesarean delivery and concerted obstetrical team can save the mother and child from catastrophic complications.

RESUMO

OBJECTIVES: (1) To compare the accuracy of vagino-rectal enriched culture (EC) and a rapid polymerase chain reaction (PCR) test for the detection of Group B streptococcus (GBS) carrier status at 35-37-week gestation and at onset of labor. (2) To assess the conversion rate of GBS carrier status between 35-37 weeks to the onset of labor according to the EC/PCR tests. A prospective study was performed at a women's health clinic, referred to give birth at one medical center. STUDY POPULATION: Low risk pregnant women at 35-37-week gestation who did not know their GBS carrier status. METHODS: Participants were evaluated for GBS status both at 35-37 weeks and at labor onset. Correlation between tests was calculated by Spearman correlation. RESULTS: One hundred and ten specimens were analyzed. Correlations: EC-PCR: 35-37 weeks - very high (r = 0.8), at labor - high (r = 0.5). EC-EC: 35-37 weeks and at labor - high (r = 0.39); PCR-PCR: 35-37 weeks and at labor- high (r = 0.7). CONCLUSIONS: Both the EC and Xpert PCR tests are accurate for detecting GBS carrier, both at 35-37 weeks and at labor onset. We did not detect a significant conversion of the GBS status from negative at 35-37 weeks to positive at onset of labor.

RESUMO

OBJECTIVE: To investigate the occurrence of the "vanishing follicle" phenomenon in women with low number of developing follicles in assisted reproduction. STUDY DESIGN: Women with ≤ 6 follicles on the day of hCG administration with ≥ 14mm diameter were prospectively studied. Primary outcome measures were disappearance of ≥14mm and all-diameter follicles on the day of oocyte pick-up compared to the day of hCG administration. RESULTS: Among the 120 women recruited, 95 were found eligible and completed the study. The "vanishing follicle" phenomenon occurred in 3.1% (95% confidence level: 0.7%-9.0%) and 18.9% (95% confidence level: 11.6%-28.3%) of cases affecting ≥14mm and all-diameter follicles, respectively. In all cases, mid-late follicular serum LH and P levels remained within normal follicular phase range and trans-vaginal scan did not show signs of ovulation. Markedly, the main significant difference between the study and control groups in the ≥14mm follicle group was serum E2 level on the day of hCG administration; median (Interquartile range), corresponding to 395 (382.0-405.5) versus 823.0 (544.5-1291.0) pg/mL, respectively (P=0.04). The same trend was encountered in all-diameter vanishing follicles group but it did not reach significance. Interestingly, in all-diameter vanishing group, chronic smoking and the P/E2 ratio on the hCG day were significantly higher than controls. Post hoc multiple logistic regression analysis of data in accordance with the Bologna criteria reveled that antral follicle count was found to significantly affect the development of the "vanishing follicle" phenomenon. CONCLUSIONS: The "vanishing follicle" phenomenon occasionally occurs in women with low number of developing follicles during assisted reproduction with no signs of ovulation. Our preliminary findings suggest that this phenomenon may be related to exhausted ovarian reserve however, an early-unrecognized LH elevation could not be ruled out.

RESUMO

The aim of this study was to determine whether the route of extended-spectrum ß-lactamase (ESBL) transmission to hospitalized newborns was from their mothers during delivery. Neonatal intensive care unit (NICU) hospitalized newborns were sampled for ESBL presence by stool cultures on the first and fourth days of life. Mothers of ESBL-positive newborns were sampled for possible correlation detection. Bacteria isolates were molecularly identified and susceptibility tests for antibiotic agents were performed. Of the 225 newborns, 14 (6.2%) were ESBL positive, 10 (4.4%) were Escherichia coli positive, and 4 (1.7%) were Klebsiella pneumoniae positive. Among the 14 mothers of positive newborns, 13 (92.8%) were found ESBL positive and one mother of a newborn with E. coli carriage was found ESBL negative. Genes encoding for ESBL resistance were identified. Antibiotic sensitivity and resistance were tested. This study demonstrated that ESBL bacteria carrier neonates hospitalized in NICU may be a result of transmission from mother to baby during delivery.

RESUMO

PURPOSE: To investigate the occurrence of multinucleated blastomeres (MNB) in poor ovarian response (POR) women defined under the Bologna criteria. METHODS: This observational study was designed in a prospective controlled manner. Among 380 cases evaluated for eligibility, 102 women were found suitable and recruited; 51 with POR in accordance with the Bologna criteria defined as the study group and 51 with normal ovarian response defined as the control group. RESULTS: Among the 51 women in each group, 8 and 2 did not achieve embryos in the study and control group, respectively (P < 0.05). The percentage of women that had at least one embryo with one MNB was significantly higher in the study as compared to the control group, corresponding to 49 and 29 %, respectively. The total number of embryos evaluated was 416; 167 in the study and 249 in the control groups. Among these embryos, the MNB rate was significantly higher in the study as compared to the control group, corresponding to 19 and 8 %, respectively. CONCLUSIONS: Blastomere multinuclearity is significantly more common in women and embryos of POR cases, defined under the Bologna criteria. Future studies are warranted to substantiate our observation that has the potential to be clinically implemented in this sub-group of women undergoing assisted reproductive technologies (ART) treatment.

RESUMO

OBJECTIVE: Although the fundamental significance of both LH and FSH for adequate ovarian folliculogenesis and steroidogenesis has been extensively discussed, the clinical implication of recombinant (r) LH to rFSH for ovarian stimulation employing the GnRH antagonist protocol remains to be elucidated. The aim of this prospective randomized controlled study was to explore whether rLH supplementation to rFSH following GnRH antagonist has an added value to the late follicular ovarian steroidogenesis in the advanced reproductive aged women. DESIGN AND SUBJECTS: Sixty-three consecutive infertile women above 35 years of age and/or with a previous low ovarian response admitted for IVF/ICSI treatment were prospectively randomized. Women in the study and control groups were similarly treated employing the rFSH 300 IU/day and the flexible GnRH antagonist 0·25 mg/day protocol. On the day of antagonist initiation, rLH 150 IU/day was added only to the study group and continued till the hCG day. RESULTS: Serum E2 level on hCG day did not significantly differ between the study and control groups, corresponding to 1268 ± 1006 and 1113 ± 669 pg/mL, respectively (P = 0·9). In the study group, the duration of GnRH antagonist administration was significantly lower than the control group corresponding to 5·0 ± 1·5 to 4·0 ± 1·5 days, respectively (P < 0·05). The total dosage of rFSH administration did not differ between the two groups. CONCLUSIONS: rLH supplementation to rFSH following GnRH antagonist administration employing the flexible protocol does not seem to significantly augment serum E2 level on the day of hCG administration in the advanced reproductive ageing women. This suggests that endogenous serum LH levels following GnRH antagonist initiation are sufficient for adequate late follicular ovarian steroidogenesis in this setting.

RESUMO

Postponement of child bearing and maternal age at first pregnancy are on the rise, contributing considerably to an increase in age-related infertility and the demand for assisted reproductive technologies (ART) treatment. This brings to the infertility clinics many women with low ovarian reserve and poor ovarian response (POR) to conventional stimulation. The Bologna criteria were released to standardize the definition of POR and pave the way for the formulation of evidence-based, efficient modalities of treatment for women undergoing IVF-ET. More than four years have passed since the introduction of these criteria and the debate is still ongoing whether a revision is due. Women with POR comprise several sub-groups with diverse baseline distinctiveness, a major issue that has fueled the discussion. Although antral follicle count (AFC) and anti-Müllerian hormone (AMH), are considered good predictors of ovarian reserve, their threshold values are still not universally standardized. Different definitions for sonographic AFC and diverse assays for AMH are held responsible for this delay in standardization. Adding established risk factors to the criteria will lead to more reliable and reproducible definition of a POR, especially in young women. The original criteria did not address the issue of oocyte quality, and the addition of risk factors may yield specific associations with quality vs. quantity. Patient's age is the best available criterion, although limited, to predict live-birth and presumably oocyte quality. High scale studies to validate these criteria are still missing while recent evidence raises concern regarding over diagnosis.

RESUMO

OBJECTIVE: Calponin, a specific smooth muscle contraction regulatory troponin-like protein, is present in large quantities in uterine smooth muscle. Serum troponin levels rise in acute myocardial infarction, and creatine phosphokinase levels rise at high physical activity, both due to destruction of cardiac and striated muscle fibers. We hypothesize that the active labor process may cause uterine smooth muscle cell damage, which may result in rising maternal serum calponin levels. This was a preliminary study, searching for a new biomarker for preterm labor. METHODS: The study group included laboring term primiparous women with a singleton fetus. The control group included similar demographic and pregnancy characteristics pregnant women not in labor. Maternal serum levels of calponin basic isoform were measured evaluated and compared in both groups. RESULTS: Study group included 100 pregnant women. Calponin serum levels were higher in the active labor (794 ± 974 ng/mL) than in the group not in labor (591 ± 587 ng/mL), although it did not reach statistical significance. Gender and neonatal weight were similar in the two study groups. CONCLUSIONS: Calponin serum levels showed moderate elevation during active labor, compared to the levels in a cohort of pregnant comparable women at the same gestational weeks but not in labor.

RESUMO

INTRODUCTION: The aim of this study was to assess the effect of mild pressure applied on the abdominal wall by the ultrasound transducer on fetal cephalic indices. MATERIAL AND METHODS: We examined by ultrasound 60 fetuses of healthy women, at 20-24 weeks of pregnancy, during routine prenatal evaluation. For every fetus biparietal diameter and head circumference were measured, with and without applying mild pressure by the ultrasound transducer. The weight and gestational age (GA) were calculated. RESULTS: The pressure applied by the transducer had a significant effect on the cephalic indices and on the weight and GA evaluations (p < 0.001). Fetal positioning significantly affected the impact that applied pressure had on head circumference and on the weight evaluation derived from it (p < 0.05). DISCUSSION: Applied pressure by an abdominal ultrasound probe affects cephalic indices and the derived weight and GA estimations. This may lead to incorrect diagnoses or hide pathological findings. The effect of applied pressure depends on fetal positioning. The examiner must be aware of this effect when evaluating the results of the measurements.

RESUMO

PURPOSE: In the last few years more robust evidence is emerging to point out at an increased rate of prematurity and low birth weight in singleton pregnancies following ART. Whether this increased rate is related to ART practice or to infertility per se, is still an open question. Our aim in this study was to explore this question by evaluating Protein C (ProC) Global assay in infertile women before ART treatment. METHODS: A cohort of 95 unselected and consecutive infertile women, eligible for ART, was prospectively recruited for the study. The control group included 77 matched healthy fertile women with a history of spontaneous conceptions. Pro C Global assay was evaluated in both groups. A full thrombophilic work-up was performed in the study group. RESULTS: ProC Global assay level was found to be significantly lower in the study as compared to the control group, corresponding to 0.78 ± 0.16 and 0.88 ± 0.16, respectively (P < 0.01). As well, abnormal ProC Global assay level of ≤ 0.8 was significantly higher in the study as compared to control group corresponding to 53 % and 29 %, respectively. ProC Global assay level was significantly lower in women within the study group found to have APCR, factor V Leiden and high factor VIII level, any thrombophilia or combined thrombophilia when compared to women without these thrombophilic risk factors. CONCLUSIONS: Reduced ProC Global assay level is encountered in infertile women prior to ART treatment. This finding may suggest a unique anticoagulation Protein C pathway in infertile as compared to fertile women. Further studies are encouraged to explore this finding.

RESUMO

OBJECTIVE: To investigate the association between thrombophilic risk factors and poor ovarian response in an assisted reproductive technologies (ART) setting. STUDY DESIGN: This is a preliminary prospective cohort study in a university affiliated reproductive medicine unit. Eighty-nine infertile women undergoing IVF-ET treatment were recruited. Following IVF-ET treatment, the 28 women that had ≤ 3 oocytes on retrieval were the study group, and the 61 women that had ≥ 4 oocytes on retrieval were the control group. All women underwent ovarian reserve testing and thrombophilia work-up prior to treatment. RESULTS: Patients' characteristics, except for chronological age, were similar between the two groups. Women in the study group had clear manifestations of low ovarian reserve, evident by ovarian reserve testing, controlled ovarian hyper-stimulation and IVF-ET treatment results, as compared to the control group. The incidence of all thrombophilias tested was similar between the study and control group. Moreover, the incidence of any single or combined thrombophilia was also similar between the two groups. Logistic regression model analysis and Pearson correlation tests did not show significant correlation between number of oocytes retrieved and thrombophilia. Furthermore, basal ovarian reserve tests did not differ between women with and without thrombophilia. When only the 48 women ≤ 35 years of were analyzed, the five women in the study group had significantly higher incidence of a single as well as combined thrombophilia as compared to the 43 controls. CONCLUSIONS: Thrombophilic risk factors have no correlation with poor ovarian response in the general infertile population undergoing ART. Whether premature low ovarian reserve is linked to thrombophilia remains to be established.

RESUMO

BACKGROUND: To evaluate the role of early follicular stromal flow studies in predicting ovarian response during IVF-ET treatment and to assess their correlation with ovarian reserve parameters and clinical pregnancy achievement. MATERIALS & METHODS: One hundred and sixty-eight consecutive and unselected infertile women undergoing their first IVF-ET treatment were included in the study. Basal ovarian reserve and stromal Doppler flow studies were performed in a natural cycle before starting treatment. Four Doppler indices were measured; peak systolic velocity (PSV), pulsatility index (PI), resistance index (RI) and systole/diastole ratio (S/D). Following completion of IVF-ET treatment Pearson's correlation analysis was performed to examine the correlation between Doppler indices, ovarian response, basal ovarian reserve parameters and clinical pregnancy achievement. RESULTS: A positive correlation was found between the number of ≥14 mm follicles on hCG day and PSV. The number of ≥14 mm follicles and retrieved oocytes had a significant negative correlation with RI and S/D ratio. As well, the number of fertilized oocytes had a significant negative correlation with S/D ratio. Absence of a Doppler signal in one or both ovaries was significantly higher in the women with poor response (31%) as compared to women with normal response (16%). In addition, RI correlated positively with basal FSH as well as FSH/LH ratio and negatively with AFC. The S/D ratio had a negative correlation with AFC (p = 0.027). A significant positive correlation between PSV, total ovarian volume (p = 0.011) and mean ovarian volume (p = 0.019) was detected. However, no correlation between all four Doppler indices and age was detected. Moreover, Doppler indices did not differ significantly between conception and non-conception cycles following IVF-ET treatment. CONCLUSIONS: Early follicular stromal Doppler signals is correlated with ovarian response as well as basal ovarian reserve parameters, but have no correlation with age neither with clinical pregnancy achievement in infertile women undergoing IVF-ET treatment.
