Local recruitment experience in a study comparing the effectiveness of a low glycaemic index diet with a low calorie healthy eating approach at achieving weight loss and reducing the risk of endometrial cancer in women with polycystic ovary syndrome (PCOS)

OBJECTIVE Feasibility of a clinical-trial comparing a low-glycaemic diet with a low-calorie healthy eating approach at achieving weight loss and reducing the risk of endometrial cancer in women with PCOS. DESIGN A pilot Randomised-Controlled-Trial using different recruitment strategies. SETTING A University Hospital in the United Kingdom. PATIENTS Women seen at specialist gynaecology clinics over a 12 month period in one University Hospital, and women self identified through a website and posters. INTERVENTIONS Potential recruits were assessed for eligibility, gave informed consent, randomised, treated and assessed as in the definitive trial. MAIN OUTCOME MEASURES Eligibility and recruitment rates, compliance with the allocated diet for 6 months and with clinical assessments, blood tests, pelvic ultrasound scans and endometrial biopsies. RESULTS 1433 new and 2598 follow up patients were seen in 153 gynaecology clinics for over 12 months. 441 (11%) potentially eligible women were identified, 19 (0.4%) of whom met the trial entry criteria. Eleven consented to take part, of which 8 (73%) completed the study. CONCLUSIONS Planned future trials on over-weight women with PCOS should be multicentre and should incorporate primary care. This data will help other researchers plan and calculate the sample size and potential recruitment rates in future clinical trials in PCOS. The results will also be useful for inclusion in future meta-analyses.

Carbetocin compared to oxytocin in emergency cesarean section: a randomized trial.

OBJECTIVE To evaluate the uterotonic effect of carbetocin compared with oxytocin in emergency cesarean delivery. STUDY DESIGN Participants were randomized to intravenous bolus injection of 100mcg carbetocin or 10IU oxytocin after cesarean delivery of the baby. The primary outcome is any additional uterotonic which may be administered by the blinded provider for perceived inadequate uterine tone with or without hemorrhage in the first 24hours after delivery. Secondary outcomes include operating time, perioperative blood loss, change in hemoglobin and hematocrit levels, blood transfusion and reoperation for postpartum hemorrhage. RESULTS Additional uterotonic rates were 107/276 (38.8%) vs. 155/271 (57.2%) [RR 0.68 95% CI 0.57-0.81 p<0.001; NNTb 6 95% CI 3.8-9.8], mean operating time 45.9±16.0 vs. 44.5±13.1minutes p=0.26, mean blood loss 458±258 vs. 446±281ml p=0.6, severe postpartum hemorrhage (≥1000ml) rates 15/276 (5.4%) vs. 10/271 (3.7%) p=0.33 and blood transfusion rates 6/276 (2.2%) vs. 10/271 (3.7%); p=0.30 for carbetocin and oxytocin arms respectively. There was only one case of re-operation (oxytocin arm). In the cases that needed additional uterotonic 98% (257/262) was started intraoperatively and in 89% (234/262) the only additional uterotonic administered was an oxytocin infusion over 6hours. CONCLUSION Fewer women in the carbetocin arm needed additional uterotonics but perioperative blood loss, severe postpartum hemorrhage, blood transfusion and operating time were not different.

The Desire for Multiple Pregnancy among Patients with Infertility and Their Partners

Objective. To study the predictors for desire for multiple pregnancies and the influence of providing information regarding the maternal and fetal complications associated with multiple pregnancies on their preference for multiple pregnancies. Methods. Couples attending an infertility clinic were offered to fill up a questionnaire separately. Following this, they were handed a pamphlet with information regarding the risks associated with multiple pregnancies. The patients will then be required to answer the question on the number of pregnancies desired again. Results. Two hundred fifty three out of 300 respondents completed the questionnaires adequately. A higher proportion of respondents, 60.3% of females and 57.9% of males, prefer singleton pregnancy. Patients who are younger than 35 years, with preexisting knowledge of risks associated with multiple pregnancies and previous treatment for infertility, have decreased desire for multiple pregnancies. However, for patients who are older than 35, with longer duration of infertility, and those patients who have preexisting knowledge of the increased risk, providing further information regarding the risks did not change their initial preferences. Conclusion. Providing and reinforcing knowledge on the risks to mother and fetus associated with multiple pregnancies did not decrease the preference for multiple pregnancies in patients.

Comparative characteristics of spermatozoa harvested and cryopreserved in culture and cryoprotectant media with or without donor serum proteins

The objectives of this study is to evaluate the efficacy of protein-free media in the preparation, holding and crypreservation of spermatazoa for use in ART. Normozoospermic semen samples (N=71) were used to compare the effects of media on the survival and quality of spermatozoa when washed and cultured with different media with and without added proteins at 4°C, 15°C, 22°C and 37°C for 0, 4-7 and 24h. Survival and quality of spermatozoa were assessed after freeze-thaw with synthetic cryoprotectant with and without proteins. Ethics/IRB approval was obtained (Ref. 1073.52). Spermatozoa parameters were similar in all media after washing and culture for 24h. Post-thaw survival and quality of spermatozoa was not significantly different 24h after thawing of samples frozen in all cryoprotectant medium. In conclusion synthetic protein-free culture and cryoprotectant media are equal in efficacy to protein-containing media in culture and cryopreservation of spermatozoa . Use of these synthetic media are anticipated to significantly reduce the risk, potentially associated with conventional protein-containing media, of transmission of disease and possibly harmful undeclared proteins to the patient, baby and the healtcare worker. Synthetic media also ensure consistency of quality between batches of media.

Date fruit consumption at term: Effect on length of gestation, labour and delivery

Abstract Labour induction and augmentation with Prostaglandin and Oxytocin are well established as standard practice worldwide. They are safe when used judiciously, but may be associated with maternal and neonatal morbidities. Other safer alternatives have been studied including dates consumption during late pregnancy with various outcomes. The aim of this randomised controlled trial was to investigate the effect of date fruit consumption during late pregnancy on the onset of labour and need for induction or augmentation of labour. A total of 154 nulliparous women with an uncomplicated singleton pregnancy were randomly allocated to either dates-consumer (77) or control group (77). The women in the dates-consumer group had significantly less need for augmentation of labour and longer intervention to delivery interval. There was no significant difference in the onset of spontaneous labour. Dates consumption reduces the need for labour augmentation but does not expedite the onset of labour. Impact statement • Dates fruit consumption during late pregnancy has been shown to positively affect the outcome of labour and delivery. In this study, date consumption reduced the need for labour augmentation with oxytocin but did not expedite the onset of labour. Therefore, dates consumption in late pregnancy is a safe supplement to be considered as it reduced the need for labour intervention without any adverse effect on the mother and child. This further supports the finding of earlier studies.

Pregnancies generated in novel synthetic protein-free embryo culture medium

concentrations (Table 1).We also found that the percentage of embryos falling within the optimal ranges defined for cc2, t5 and s2 were different between the two groups as showed in Table 2. Based on these results we decided to perform a more detailed analysis in order to find the implications of O2 concentration for D3 embryo selection based on kinetic parameters.
