Abstract
OBJECTIVES To determine cardiovascular, obstetric and neonatal outcomes of pregnancies in women who have a Fontan circulation. METHODS A retrospective case note review of all women with a Fontan circulation who attended the joint obstetric cardiac antenatal clinic at St Mary's Hospital, Manchester (UK) between 2004 and 2016 was performed. RESULTS In total, there were 19 pregnancies in 9 women with a history of Fontan repair. 23 women with univentricular physiology attended in this time period. 10 pregnancies (53%) resulted in live births; 1 in a stillbirth at 31 weeks gestation and 8 in miscarriage. Cardiovascular complications occurred in 2 pregnancies (11%). There were no thrombotic events, arrhythmias, myocardial infarction, or endocarditis in the antenatal or postnatal period. Obstetric complications included miscarriage (26% first trimester, 16% second trimester), along with premature delivery (24-36+6) (80%) and fetal growth restriction (70%). The majority of women were delivered by caesarean section (60%). CONCLUSIONS Women who become pregnant following a Fontan repair carry an increased risk of cardiovascular complications. Fetal and neonatal complication rates are high and emphasize the importance of thorough, multidisciplinary, pre-conceptual assessment and counseling to allow patients to make informed decisions regarding future pregnancy.

Abstract
The goal of this project is to promote Lyme disease prevention and to cultivate an interest in science through a citizen-science project coordinated by researchers at a public university and teachers at rural high schools. The lesson plan is designed to increase student interest in pursuing a science career through participation in an authentic research experience, utilizing a topic that has implications on the health of the surrounding community. Students are introduced in the classroom to zoonotic diseases transmitted by the Ixodes tick, the health risks of Lyme disease, and disease prevention strategies. Students then participate in a research experience collecting field data and ticks from their community, which are used in university research. To measure changes in student knowledge and attitudes toward Lyme disease and science careers, students completed surveys related to the learning objectives associated with the experience. We found participation in the activity increased student confidence and ability to correctly differentiate a deer tick from a wood tick and to recognize the symptoms of Lyme disease. In addition, students reported increased interest in pursuing a science degree in college or graduate school. Authentic research experience related to a disease relevant to the local community is effective at enhancing high school student engagement in science.

Abstract
With the primary objective of attracting and retaining students from underrepresented backgrounds in the sciences, evaluation of one institution's program has been ongoing over the past three years. Interviews with mentors in the program followed by focus groups conducted with mentees reveal key factors that shape undergraduate students' research experiences. In the present study, attention is given to data gathered from 15 mentees in the program, the majority of whom have enrolled in community colleges, represent low socioeconomic backgrounds, and are nontraditional students. The results from focus groups with the mentees provide information on the benefits of participating in the program, characteristics of good mentors, challenges to the mentoring relationship, and the effects of underrepresented status on pursuit of advanced degrees. Comparisons of mentees' comments about the mentoring relationship with mentors' comments reveal similar themes and patterns while also demonstrating interesting differences. The qualitative findings are also juxtaposed with participants' responses on the Survey of Undergraduate Research Experiences. Taken together, the data enhance our understanding of the experiences of underrepresented students in faculty-mentored research programs and highlight challenges and perspectives of students who are transferring to the university from a community college.

Abstract
A prospective clinical study was carried out to evaluate the influence of posture on perineal ultrasound imaging parameters. One hundred and thirty-two consecutive women presenting with symptoms of lower urinary tract dysfunction were examined by multichannel videourodynamics and perineal ultrasound, both supine and standing. Ultrasound included color Doppler imaging when available, i.e. in a subgroup of 99 patients. The position of the bladder neck at rest was higher in the supine position (P<0.001) and it descended further on Valsalva (P < 0.001), to reach an almost identical final position. There was a higher degree of urethral rotation on supine imaging (P = 0.001). Urethral funneling on Valsalva was more likely in the erect position (P < 0.001), as was urine leakage documented by color Doppler imaging (P < 0.001). The effect of a pelvic floor contraction was not significantly influenced by posture. Imaging of the urethrovesical junction should be undertaken in both supine and erect positions to document optimally both hypermobility and funneling or leakage.

Abstract
Consider a regression problem in which there are many more explanatory variables than data points, i.e., p ≫ n. Essentially, without reducing the number of variables inference is impossible. So, we group the p explanatory variables into blocks by clustering, evaluate statistics on the blocks and then regress the response on these statistics under a penalized error criterion to obtain estimates of the regression coefficients. We examine the performance of this approach for a variety of choices of n, p, classes of statistics, clustering algorithms, penalty terms, and data types. When n is not large, the discrimination over number of statistics is weak, but computations suggest regressing on approximately [n/K] statistics where K is the number of blocks formed by a clustering algorithm. Small deviations from this are observed when the blocks of variables are of very different sizes. Larger deviations are observed when the penalty term is an Lq norm with high enough q.

Abstract
Background: The Notch signalling pathway has been implicated in tumour initiation, progression, angiogenesis and development of resistance to vascular endothelial growth factor (VEGF) targeting, providing a rationale for the combination of RO4929097, a γ-secretase inhibitor, and cediranib, a VEGF receptor tyrosine kinase inhibitor. Methods: Patients received escalating doses of RO4929097 (on a 3 days-on and 4 days-off schedule) in combination with cediranib (once daily). Cycle 1 was 42 days long with RO4929097 given alone for the first 3 weeks followed by the co-administration of both RO4929097 and cediranib starting from day 22. Cycle 2 and onwards were 21 days long. Soluble markers of angiogenesis were measured in plasma samples. Archival tumour specimens were assessed for expression of three different components of Notch signalling pathway and genotyping. Results: In total, 20 patients were treated in three dose levels (DLs). The recommended phase II dose was defined as 20 mg for RO4929097 on 3 days-on and 4 days-off schedule and 30 mg daily for cediranib. The most frequent treatment-related adverse events (AEs) were diarrhoea, hypertension, fatigue and nausea. Eleven patients had a best response of stable disease and one patient achieved partial response. We did not detect any correlation between tested biomarkers of angiogenesis or the Notch pathway and treatment effect. There was no correlation between mutational status and time to treatment failure. Conclusion: RO4929097 in combination with cediranib is generally well tolerated at the DLs tested. Preliminary evidence of antitumour efficacy with prolonged disease stabilisation in some patients with progressive malignancies warrants further clinical investigation of this treatment strategy.
