Abstract
Introduction Vacuum extraction is generally considered an operator-dependent task, with most attention directed toward the obstetrician's technical abilities (1-3). Little is known about the effect of the team and non-technical skills on clinical outcomes in vacuum-assisted delivery. This study aimed to investigate whether the non-technical skills of obstetricians were correlated with their level of clinical performance via the analysis of video recordings of teams conducting actual vacuum extractions. Methods We installed between two or three video cameras in each delivery room at Aarhus University Hospital and Horsens Regional Hospital and obtained 60 videos of teams managing vacuum extraction. Appropriate consent was obtained. Two raters carefully reviewed the videos and assessed the teams' non-technical skills using the Assessment of Obstetric Team Performance (AOTP) checklist, rating all items on a Likert scale score from 1 to 5 (1 = poor; 3 = average; and 5 = excellent). This resulted in a total score ranging from 18 to 90. Two different raters independently assessed the teams' clinical performance (adherence to clinical guidelines) using the TeamOBS-Vacuum-Assisted Delivery (VAD) checklist, rating each item (0 = not done, 1 = done incorrectly; and 2 = done correctly). This resulted in a total score with the following ranges (low clinical performance: 0-59; average: 60-84; and high: 85-100). Interrater agreement was analyzed using intraclass correlation (ICC), and the risk of high or low clinical performance was analyzed on a logit scale to meet the assumption of normality. Results Teams that received excellent non-technical scores had an 81% probability of achieving high clinical performance, whereas this probability was only 12% among teams with average non-technical scores (p < 0.001). Teams with a high clinical performance often had excellent behavior in the non-technical items of "team interaction," "anticipation," "avoidance fixation," and "focused communication." Teams with a low or average clinical performance often neglected to consider analgesia, had delayed abandonment of the attempted vaginal delivery and insufficient use of appropriate fetal monitoring. Interrater reliability was high for both rater-teams, with an ICC for the non-technical skills of 0.83 (95% confidence interval [CI]: 0.71-0.88) and 0.84 for the clinical performance (95% CI: 0.74-0.90). Conclusion Although assisted vaginal delivery by vacuum extraction is generally considered to be an operator-dependent task, our findings suggest that teamwork and effective team interaction play crucial roles in achieving high clinical performance. Teamwork helped the consultant anticipate the next step, avoid fixation, ensure adequate analgesia, and maintain thorough fetal monitoring during delivery.

Abstract
Ten cases of small intestinal tympany with or without volvulus were documented in Central American river turtles (Dermatemys mawii). These turtles were under managed care at the Philadelphia Zoo in Philadelphia, PA, USA, with one case followed after transfer to a different institution. The primary clinical presentation was abnormal buoyancy in nearly all cases (9/10) and anorexia in two cases (2/10). Five of 10 turtles with suspected or radiographically confirmed small intestinal tympany recovered (5/10), whereas five cases (5/ 10) resulted in death or euthanasia. In all fatal cases (5/5), small intestinal volvulus was identified at gross necropsy, with concurrent colonic volvulus identified in 2/5 cases. Other notable necropsy findings were hepatic lipidosis (3/5) and thrombosis of intestinal or renal vasculature (2/5). In all fatal cases (5/5), there was short (1 to 2 days) clinical progression from abnormal buoyancy to death or euthanasia. In the majority of cases (6/10), an abrupt change in diet, notably the overfeeding of fresh fruit or excessive amounts of mulberry (Morus spp.) browse, or ingestion of indigestible foreign material, occurred prior to presentation. Temporary suboptimal environmental temperatures were suspected prior to the onset of clinical signs in 4/10 cases. Optimal husbandry conditions including nutrition and environmental temperature appear vital to preventing this condition. Recognition of early clinical signs of this condition, such as abnormal buoyancy and anorexia, and environmental correction or medical therapy, may prevent fatality and result in a better outcome in these cases.

Abstract
OBJECTIVE To assess the cost-effectiveness of mifepristone and misoprostol (MifeMiso) compared with misoprostol only for the medical management of a missed miscarriage. DESIGN Within-trial economic evaluation and model-based analysis to set the findings in the context of the wider economic evidence for a range of comparators. Incremental costs and outcomes were calculated using nonparametric bootstrapping and reported using cost-effectiveness acceptability curves. Analyses were performed from the perspective of the UK's National Health Service (NHS). SETTING Twenty-eight UK NHS early pregnancy units. SAMPLE A cohort of 711 women aged 16-39 years with ultrasound evidence of a missed miscarriage. METHODS Treatment with mifepristone and misoprostol or with matched placebo and misoprostol tablets. MAIN OUTCOME MEASURES Cost per additional successfully managed miscarriage and quality-adjusted life years (QALYs). RESULTS For the within-trial analysis, MifeMiso intervention resulted in an absolute effect difference of 6.6% (95% CI 0.7-12.5%) per successfully managed miscarriage and a QALYs difference of 0.04% (95% CI -0.01 to 0.1%). The average cost per successfully managed miscarriage was lower in the MifeMiso arm than in the placebo and misoprostol arm, with a cost saving of £182 (95% CI £26-£338). Hence, the MifeMiso intervention dominated the use of misoprostol alone. The model-based analysis showed that the MifeMiso intervention is preferable, compared with expectant management, and this is the current medical management strategy. However, the model-based evidence suggests that the intervention is a less effective but less costly strategy than surgical management. CONCLUSIONS The within-trial analysis found that based on cost-effectiveness grounds, the MifeMiso intervention is likely to be recommended by decision makers for the medical management of women presenting with a missed miscarriage. TWEETABLE ABSTRACT The combination of mifepristone and misoprostol is more effective and less costly than misoprostol alone for the management of missed miscarriages.

Abstract
BACKGROUND An obstetrician on standby assessed an 18-year-old primiparous captive gorilla with a term singleton fetus with a protracted labor course. CASE After it was determined that an arrest of descent had occurred, a viable, 2,280 g male neonate was delivered through an operative vaginal birth with forceps assistance without major complications. CONCLUSION Given the numerous anatomic and biochemical similarities of humans and other great apes, it is possible that the high maternal mortality and stillbirth rates of gorillas could be reduced by using the same principles of obstetric management in a multidisciplinary fashion.

Abstract
OBJECTIVES To assess the cost-effectiveness of progesterone compared with placebo in preventing pregnancy loss in women with early pregnancy vaginal bleeding. DESIGN Economic evaluation alongside a large multi-centre randomised placebo-controlled trial. SETTING Forty-eight UK NHS early pregnancy units. POPULATION Four thousand one hundred and fifty-three women aged 16-39 years with bleeding in early pregnancy and ultrasound evidence of an intrauterine sac. METHODS An incremental cost-effectiveness analysis was performed from National Health Service (NHS) and NHS and Personal Social Services perspectives. Subgroup analyses were carried out on women with one or more and three or more previous miscarriages. MAIN OUTCOME MEASURES Cost per additional live birth at ≥34 weeks of gestation. RESULTS Progesterone intervention led to an effect difference of 0.022 (95% CI -0.004 to 0.050) in the trial. The mean cost per woman in the progesterone group was £76 (95% CI -£559 to £711) more than the mean cost in the placebo group. The incremental cost-effectiveness ratio for progesterone compared with placebo was £3305 per additional live birth. For women with at least one previous miscarriage, progesterone was more effective than placebo with an effect difference of 0.055 (95% CI 0.014-0.096) and this was associated with a cost saving of £322 (95% CI -£1318 to £673). CONCLUSIONS The results suggest that progesterone is associated with a small positive impact and a small additional cost. Both subgroup analyses were more favourable, especially for women who had one or more previous miscarriages. Given available evidence, progesterone is likely to be a cost-effective intervention, particularly for women with previous miscarriage(s). TWEETABLE ABSTRACT Progesterone treatment is likely to be cost-effective in women with early pregnancy bleeding and a history of miscarriage.

Abstract
OBJECTIVE The aim of this study was to estimate the incidence of anaphylaxis in pregnancy and describe the management and outcomes in the UK. DESIGN A population-based descriptive study using the UK Obstetric Surveillance System (UKOSS). SETTING All consultant-led maternity units in the UK. POPULATION All pregnant women who had anaphylaxis between 1 October 2012 and 30 September 2015. Anaphylaxis was defined as a severe, life-threatening generalised or systemic hypersensitivity reaction. METHODS Prospective case notification using UKOSS. MAIN OUTCOME MEASURES Maternal mortality, severe maternal morbidity, neonatal mortality and severe neonatal morbidity. RESULTS There were 37 confirmed cases of anaphylaxis in pregnancy, giving an estimated incidence of 1.6 (95% CI: 1.1-2.2) per 100 000 maternities. Four cases of anaphylaxis were in women with known penicillin allergies: two received co-amoxiclav and two cephalosporins. Twelve women had anaphylaxis following prophylactic use of antibiotics at the time of a caesarean delivery. Prophylactic use of antibiotics for Group B streptococcal infection accounted for anaphylaxis in one woman. Two women died (5%), 14 (38%) women were admitted to intensive care and seven women (19%) had one or more additional severe maternal morbidities, which included three haemorrhagic events, two cardiac arrests, one thrombotic event and one pneumonia. No infants died; however, in those infants whose mother had anaphylaxis before delivery (n = 18) there were seven (41%) neonatal intensive care unit admissions, three preterm births and one baby was cooled for neonatal encephalopathy. CONCLUSIONS Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration. This study highlights the seriousness of the outcomes of this condition for the mother. The low incidence is reassuring given the large proportion of the pregnant population that receive prophylactic antibiotics during delivery. TWEETABLE ABSTRACT Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration.

Abstract
O-ring retractors (Alexis/Mobius) have been shown to reduce the risk of Surgical site infection (SSI) following general abdominal surgery. The benefit at caesarean section (CS) remains to be established given the relatively high cost. OBJECTIVES To assess the efficacy of O-ring retractors when used at CS. STUDY DESIGN Systematic review and meta-analysis. Electronic databases were searched from inception of each database until January 2018. No language restrictions were applied. All randomised controlled trials (RCTs) which compared the use of an O-ring retractor to routine care at CS were included. Primary outcome was SSI. Secondary outcomes were operating time, estimated blood loss, need for blood transfusion, need to exteriorise the uterus, requirement for additional postoperative analgesia and adequate operative field visualisation. Analysis was performed using Revman 5.3. RESULTS 6 RCTs were included in the qualitative synthesis and the meta-analysis. This included 1669 women. The use of O-ring retractors did not reduce the risk of SSI when used at CS RR 0.76 (95% CI 0.34-1.70). Nor did the use of O-ring retractors reduce the operating time, estimated blood loss, the need for blood transfusion or the need for additional postoperative analgesia. The use O-ring retractors did reduce the need for exteriorisation of the uterus RR 0.48 (95% CI 0.33-0.69), and did increase the rate of adequate visualisation of the operative field RR 1.05 (95% CI 1.00-1.10). In a planned subgroup analysis there was a reduction in the rate of SSI with the use of O-ring retractors in women with a BMI < 35 RR 0.34(95% CI 0.12-0.98). CONCLUSION This review has shown that O-ring retractors do not reduce the incidence of the common measurable complications of CS; SSI, blood loss, need for blood transfusion and need for additional postoperative analgesia. There may be a subgroup where these retractors are useful, but present evidence does not justify their routine use at CS.

Abstract
OBJECTIVES To assess the diagnostic accuracy of placental growth factor (PlGF) and ultrasound parameters to predict delivery of a small-for-gestational-age (SGA) infant in women presenting with reduced symphysis-fundus height (SFH). METHODS This was a multicenter prospective observational study recruiting 601 women with a singleton pregnancy and reduced SFH between 24 and 37 weeks' gestation across 11 sites in the UK and Canada. Plasma PlGF concentration < 5(th) centile, estimated fetal weight (EFW) < 10(th) centile, umbilical artery Doppler pulsatility index > 95(th) centile and oligohydramnios (amniotic fluid index < 5 cm) were compared as predictors for a SGA infant < 3(rd) customized birth-weight centile and adverse perinatal outcome. Test performance statistics were calculated for all parameters in isolation and in combination. RESULTS Of the 601 women recruited, 592 were analyzed. For predicting delivery of SGA < 3(rd) centile (n = 78), EFW < 10(th) centile had 58% sensitivity (95% CI, 46-69%) and 93% negative predictive value (NPV) (95% CI, 90-95%), PlGF had 37% sensitivity (95% CI, 27-49%) and 90% NPV (95% CI, 87-93%); in combination, PlGF and EFW < 10(th) centile had 69% sensitivity (95% CI, 55-81%) and 93% NPV (95% CI, 89-96%). The equivalent receiver-operating characteristics (ROC) curve areas were 0.79 (95% CI, 0.74-0.84) for EFW < 10(th) centile, 0.70 (95% CI, 0.63-0.77) for low PlGF and 0.82 (95% CI, 0.77-0.86) in combination. CONCLUSIONS For women presenting with reduced SFH, ultrasound parameters had modest test performance for predicting delivery of SGA < 3(rd) centile. PlGF performed no better than EFW < 10(th) centile in determining delivery of a SGA infant.

Abstract
The importance of the left hemisphere in language function has been firmly established and current work strives to understand regional specializations within the perisylvian language areas. This paper reports a case study of a deaf user of American Sign Language undergoing an awake cortical stimulation mapping procedure. Patterns of sign errors accompanying electrical stimulation of Broca's area and the supramarginal gyrus (SMG) are reported. Our findings show Broca's area to be involved in the motor execution of sign language. These data demonstrate that the linguistic specificity of Broca's area is not limited to speech behavior. In addition, unusual semantic-phonological errors were observed with stimulation to the SMG; these data may implicate the SMG in the binding of linguistic features in the service of language production. Taken together, these findings provide important insight into the linguistic specificity of Broca's area and the functional role of the supramarginal gyrus in language processing.

Abstract
OBJECTIVES To estimate and compare the costs of surgical and medical treatment of miscarriage to the National Health Service. DESIGN A patient-centred, partially randomised trial. SETTING A teaching hospital in Scotland. PARTICIPANTS Four hundred and thirty-seven women with a proven first trimester miscarriage. MAIN OUTCOME MEASURES The cost per patient of surgical and medical management of miscarriage plus the extra cost per patient of introducing medical management of miscarriage under three different scenarios are calculated. RESULTS The average cost of surgical treatment was Pounds 397 compared with Pounds 347 for medical treatment. Sensitivity analysis showed that the extra cost of introducing the medical management of miscarriage ranged from a cost saving of Pounds 71 per patient to an additional cost of Pounds 47 per patient. CONCLUSIONS Our analysis showed that it may be possible to generate cost savings by introducing medical methods in the management of early miscarriage. However, the savings assume that costs associated with theatre use can be fully realised.

Abstract
The objective of this work was to study the abortifacient effects of misoprostol, an orally active prostaglandin E1 (PGE1) analogue, in the second trimester. A randomized study of two prostaglandin regimens in women pre-treated with the antiprogesterone mifepristone was carried out in the gynaecological wards of Aberdeen Royal Hospitals, NHS Trust, and included 60 women at 13-20 weeks' gestation, in whom termination of pregnancy had been agreed. Following pre-treatment with mifepristone 600 mg women were randomly allocated to one of two prostaglandin regimens which started 36-48 h later. The first misoprostol 400 micrograms orally (up to three doses) followed by gemeprost vaginal pessary 1 mg up to two doses. The second was gemeprost vaginal pessary 1 mg up to five doses. The main outcome measures were success rate induction-to-abortion interval and side-effects. There were no significant differences between the two groups in any of the main outcome measures. We conclude that misoprostol is a stable, cheap PGE1 analogue with demonstrable efficacy and acceptable side-effects in the management of second trimester abortion. Further work is needed to establish the optimum dose and regimen.

Abstract
The relative merits of cystoscopy alone and cystoscopy plus urethral dilatation were compared in a randomised study of women with recurrent frequency and dysuria. One hundred women were studied before and at least 6 months after operation. A detailed questionnaire was completed, the severity of the symptoms was scored and patients underwent urodynamic investigation. Forty-eight patients underwent cystoscopy alone and 52 underwent urethral dilatation. The two groups were well matched with regard to age, parity, menopausal status, previous gynaecological surgery and severity of symptoms. A significant improvement in symptoms was observed in both groups after treatment: 30% had no residual symptoms, 50% were improved and 20% were no better. However, no difference in final outcome was observed between those who had undergone cystoscopy alone and those who had undergone urethral dilatation. Furthermore, 7 patients who underwent urethral dilatation experienced transient stress incontinence of urine, a complication not observed in women who underwent cystoscopy alone. No benefit was observed from the addition of urethral dilatation to cystoscopy alone in women with recurrent frequency and dysuria.

Abstract
Near-total (95 percent) pancreatectomy with intraportal islet autotransplantation was performed in five patients with chronic pancreatitis. Two patients are completely insulin-independent 7 and 14 months after autotransplantation; the other three patients obtained partial independence. A new method of islet cell preparation is described. Islet cell autotransplantation after total or near-total pancreatectomy should at present be viewed with cautious optimism. Additional cases need to be studied and followed up before its role in the surgery of chronic pancreatitis will be clear.
