OBJECTIVE:: To estimate the incidence of antenatal stroke in the United Kingdom and to describe risk factors associated with stroke during pregnancy, management, and outcomes. METHODS:: A population-based (nationwide) cohort and nested case-control study was conducted using the UK Obstetric Surveillance System between October 2007 and March 2010. We investigated the potential factors associated with antenatal stroke using a logistic regression analysis to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS:: Thirty cases of antenatal stroke were reported giving an estimated incidence of 1.5 cases per 100,000 women delivering (95% CI 1.0-2.1). The incidences of nonhemorrhagic and hemorrhagic stroke were 0.9 (95% CI 0.5-1.3) and 0.6 (95% CI 0.3-1.0) per 100,000 women delivering. Factors associated with increased risk of antenatal stroke were history of migraine (adjusted OR 8.5, 95% CI 1.5-62.1), gestational diabetes (adjusted OR 26.8, 95% CI 3.2-), and preeclampsia or eclampsia (adjusted OR 7.7, 95% CI 1.3-55.7). There was wide variation in the use of pharmacologic, surgical, and organized stroke unit care. There were six stroke-related maternal deaths giving a case-fatality rate of 20% of all strokes, 50% of hemorrhagic strokes, and a mortality rate of 0.3 (95% CI 0.1-0.6) per 100,000 women delivering. CONCLUSION:: The risk of a stroke during pregnancy is low; however, the poor outcomes in terms of morbidity and mortality and variations in care highlight the importance of such women receiving specialist stroke care. Clinicians should be aware of an association with a history of migraine, gestational diabetes, and preeclampsia or eclampsia. I© 2012 by Lippincott Williams & Wilkins.

Background: Bronchopulmonary dysplasia (BPD) is a commonly used outcome for randomized neonatal trials. Objectives: The aim of the present study was to determine whether a diagnosis of BPD or respiratory morbidity (RM1 or RM2) at 12 months corrected age better predicted subsequent RM in extremely low gestational age infants (23-28 weeks of gestation). Methods: Initial analysis was undertaken in a development cohort of 76 infants who underwent pulmonary function tests (PFTs) at 12 months corrected age. Parents completed infant respiratory diaries 2 weeks before the PFTs. Analysis was then undertaken in a validation cohort of 227 infants whose parents completed a 4-week respiratory diary when their infant was 12 months corrected age. BPD at 28 days (BPD28d) and 36 weeks post-menstrual age (BPD36w), RM1 (≥3 days and/or nights of cough, wheeze, and/or medicine use) and RM2 (≥4 days and/or nights of cough, wheeze, and/or respiratory medicine use) each week for 2 weeks at 12 months corrected age were assessed with regard to prediction of respiratory outcomes at 24 months documented by respiratory health questionnaires. Results: BPD28d and BPD36w were not significantly associated with any respiratory outcome. Areas under the receiver operating characteristic curves were significantly better for either definition of RM than BPD28d or BPD36w for all outcomes. Conclusions: RM documented by parental completed diaries at 12 months corrected age better predicted respiratory outcome at 24 months corrected age than BPD regardless of diagnostic criteria. © 2015 S.

In 2005, the European Society for Human Reproduction and Embryology (ESHRE) PGD Consortium published a set of Guidelines for Best Practice PGD to give information, support and guidance to potential, existing and fledgling PGD programmes. Subsequent years have seen the introduction of new technologies as well as the evolution of current techniques. Additionally, in light of recent advice from ESHRE on how practice guidelines should be written/formulated, the Consortium believed it was timely to update the PGD guidelines. Rather than one document that covers all of PGD, the new guidelines are separated into four documents, including one relating to organization of the PGD centre and three relating to the methods used: DNA amplification, fluorescence in situ hybridization and biopsy/embryology. Here, we have updated the sections on organization of the PGD centre. One area that has continued to expand is Transport PGD, in which patients are treated at one IVF centre, whereas their gametes/embryos are tested elsewhere, at an independent PGD centre. Transport PGD/preimplantation genetic screening (PGS) has a unique set of challenges with respect to the nature of the sample and the rapid turn-around time required. PGS is currently controversial. Opinions of laboratory specialists and clinicians interested in PGD and PGS have been taken into account here. Current evidence suggests that PGS at cleavage stages is ineffective, but whether PGS at the blastocyst stage or on polar bodies might show improved delivery rates is still unclear. Thus, in this revision, PGS has been included. This document should assist everyone interested in PGD/PGS in developing the best laboratory and clinical practice possible. © 2010 The Author.

Background: The purpose of this study was to determine attitudes to, and provision of, extended regimens for taking the combined oral contraceptive pill (COC) by specialist contraception practitioners from three contrasting specialist contraception services in London. Methods: An online cross-sectional survey was administered to all doctors and nurses, who counsel, provide, or prescribe the oral contraceptive pill at each clinic. Results: A total of 105 clinicians received the questionnaire and 67 (64%) responded. Only one of three clinics initiated and maintained guidelines for extended COC use. In that service, 60% of staff prescribing COC advised more than 50% of patients regarding alternative COC regimens. In the other two services, this was discussed with 20% and 6% of patients, respectively (P < 0.001). The reasons for prescribing extended use included cyclic headaches, menorrhagia, patient request, menstrual-related cramps, and endometriosis, and did not differ between the three different settings. The most common extended regimens were 63 pills or continuous use until bleeding occurs, followed by a hormone-free interval. Concerns highlighted by providers and patients were "unhealthy not to have a monthly bleed", "future fertility", and "breakthrough bleeding". Such comments highlight the need for further information for providers and patients. Conclusion: There is growing evidence, backed by national guidance, about extended COC use, but routine provision of this information is patchy and varies ten-fold, even within specialist family planning services. Targeted training, use of service guidelines, and implementation research will be needed to extend patient choice of different COC regimens and change clinical practice. © 2013 Sauer et al.

Objectives: The position of the conus medullaris is considered abnormal if it ends below lumbar vertebrae three (L3) at birth. We used magnetic resonance imaging (MRI) to measure the position of the conus in post-mortem foetuses, to investigate the timing of normal ascent. Methods: The position of the conus in 84 post-mortem foetuses (mean gestation 26.3 weeks; range 14-41 weeks) was identified using 3D MRI datasets. A numerical scale was used for vertebral levels, from 1 (S2) to 15 (T12). Results: There was significant ascent of the conus medullaris with increasing gestation. At 20 weeks gestation, an estimated 84.2% (95% confidence interval (CI): 72.9, 93.2%) of foetuses have a conus position of L4/5 or higher, but only 22.8% (95% CI 11.7, 34.9%) at L3 or higher. By 26 weeks, an estimated 50.7% (95% CI 34.1, 67.5) will have reached L3, and 94.8% (95% CI 87.0, 98.5%) reach L3 by 40 weeks. Conclusion: There is regular ascent of the conus throughout foetal life. Although growth for each individual foetus may be non-linear, most foetuses have a conus level within the normal adult range by 33 weeks gestation. © 2013 Informa UK Ltd All rights reserved.

The functions of the Ndc80/Hec1 subunit of the highly conserved Ndc80 kinetochore complex are normally restricted to M phase when it exerts a pivotal kinetochore-based role. Here, we find that in mouse oocytes, depletion of Hec1 severely compromises the G2-M transition because of impaired activation of cyclin-dependent kinase 1 (Cdk1). Unexpectedly, impaired M phase entry is due to instability of the Cdk1-activating subunit, cyclin B2, which cannot be covered by cyclin B1. Hec1 protects cyclin B2 from destruction by the Cdh1-activated anaphase-promoting complex (APCCdh1) and remains important for cyclin B2 stabilization during early M phase, required for the initial stages of acentrosomal spindle assembly. By late M phase, however, Hec1 and cyclin B2 become uncoupled, and although Hec1 remains stable, APCCdc20 triggers cyclin B2 destruction. These data identify another dimension to Hec1 function centered on M phase entry and early prometaphase progression and challenge the view that cyclin B2 is completely dispensable in mammals. © 2013 Elsevier Inc.

Background.Gabapentin (GPT), a widely used drug in neurology, has been proposed as a non-hormonal option for the management of hot flushes in menopausal women with contraindications for estrogen therapy. Objective.To compare GPT versus low-dose transdermal estradiol (E2) for treating post-menopausal women with moderate to very severe hot flushes. Methods.A total of 45 post-menopausal women with moderate to very severe hot flushes were prospectively and single-blinded randomised to receive oral GPT 600mg/night or transdermal 25 μg/day E2 per week. Hot flush intensity and frequency were assessed with the Menopause Rating Scale and a numeric scale respectively at baseline and at 1, 4 and 8 weeks. Side effects were also assessed. Results.Hot flush intensity and frequency significantly decreased for both groups at 1, 4 and 8 weeks of treatment as compared to baseline; however, this decrease was statistically more evident for the E2 group. Although the percentage of hot flush intensity and frequency reduction at the end of the treatment was higher for E2, this was not statistically significant (68.2 vs. 60.6 for intensity and 70.1 vs. 58.9 for frequency, respectively, p>0.05, NS). Encountered side effects included: drowsiness, dizziness, fatigue (GPT group) and mastodynia, vaginal spotting and a local allergic reaction (E2 group). Compliance to treatment was 95.6 (GPT group) as compared to 90.9 for the E2 group. Conclusion.Despite statistical significant differences, from a clinical point of view oral GPT 600mg was as effective as low-dose transdermal E2 in controlling moderate to severe hot flushes in post-menopausal women, and should be recommended as an alternative option in those with contraindications to estrogen therapy. More research is warranted in this regard. © 2010 Informa UK Ltd.

Screening for fragile X premutations is recommended for the routine work-up for any woman presenting with premature ovarian failure (POF). The reason for this is that women with POF have an approximate 5% chance of conceiving and this possibility may be increased further in the FRAXA premutation subgroup. Women need to be informed if they are at risk of having a child with fragile X syndrome. In addition, the identification of a family in which the fragile X repeat site is expanded can lead to the identification of other female family members at risk of transmitting fragile X syndrome. The identification of an index case should therefore trigger genetic counseling throughout the pedigree according to the wishes of the family. © 2010.

An employer has a legal requirement to offer a safe working environment to its employees. The risks and hazards should be reduced as far as practicably possible, and the set-up should be as ergonomic as possible. Modern laparoscopic surgery carried out in an old-fashioned theatre without the advantages that an integrated operating room has to offer results in increased risk of injury to the staff. We have assessed the relative risks and determined reasons why modernisation is essential to the safety of the theatre team. © 2012 Springer-Verlag Berlin Heidelberg.

To evaluate the effects of sex and menopausal status on acute-, continuation-, and maintenance-phase treatment outcomes in patients with recurrent major depressive disorder (MDD).This was a secondary analysis of data from the Prevention of Recurrent Episodes of Depression With Venlafaxine for Two Years (PREVENT) trial, a multiphase, multicenter, double-blind study in which adult outpatients with recurrent MDD (by DSM-IV criteria) were randomly assigned to 10 weeks of acute-phase venlafaxine extended release (ER) (75-300 mg/d) or fluoxetine (20-60 mg/d). Patients achieving response or remission had 6 months of continuation-phase treatment. Responding or remitting patients in the venlafaxine ER group were randomly assigned to venlafaxine ER or placebo for 2 consecutive 12-month maintenance phases; fluoxetine-treated patients continued receiving fluoxetine. The outcome measures for this analysis were acute- and continuation-phase response and remission rates (as measured by the 17-item Hamilton Depression Rating Scale) and time to depression recurrence in the maintenance phases according to sex and menopausal status at baseline.The intent-to-treat population comprised 781 patients in the venlafaxine ER group (65% women) and 266 patients in the fluoxetine group (61% women); 64% of all women were premenopausal, and 25% were postmenopausal (5% perimenopausal; not analyzed). At acute-phase end, remission rates in the venlafaxine ER vs fluoxetine groups were 44% vs 47% in men, 51% vs 52% in women, 50% vs 52% in premenopausal women, and 52% vs 55% in postmenopausal women. At continuation-phase end, remission rates in the venlafaxine ER vs fluoxetine groups were 71% vs 74% in men, 72% vs 67% in women, 72% vs 69% in premenopausal women and 71% vs 63% in postmenopausal women. Response rates were consistent with these findings. Based on a Cox proportional hazards model, sex was not a significant predictor of recurrence during the first or second maintenance phase (hazard ratio [HR] = 1.233; P = .3712 and HR = 1.103; P = .8075, respectively), and neither was menopausal status at acute-phase baseline (HR = 0.941; P = .8234 and HR = 0.531; P = .2065, respectively).In this study of patients with recurrent MDD, treatment outcomes with venlafaxine ER and fluoxetine did not differ on the basis of sex or menopausal status. Our confidence in these findings is limited by the lack of a placebo arm during the acute and continuation phases and by the small sample sizes for subgroup analyses in the maintenance identifier: NCT00046020.
