RESUMO
OBJECTIVE: Investigate cost-effectiveness of first trimester pre-eclampsia screening using the Fetal Medicine Foundation (FMF) algorithm and targeted aspirin prophylaxis in comparison with standard care. DESIGN: Retrospective observational study. SETTING: London tertiary hospital. POPULATION: 5957 pregnancies screened for pre-eclampsia using the National Institute for Health and Care Excellence (NICE) method. METHODS: Differences in pregnancy outcomes between those who developed pre-eclampsia, term pre-eclampsia and preterm pre-eclampsia were compared by the Kruskal-Wallis and Chi-square tests. The FMF algorithm was applied retrospectively to the cohort. A decision analytic model was used to estimate costs and outcomes for pregnancies screened using NICE and those screened using the FMF algorithm. The decision point probabilities were calculated using the included cohort. MAIN OUTCOME MEASURES: Incremental healthcare costs and QALY gained per pregnancy screened. RESULTS: Of 5957 pregnancies, 12.8% and 15.9% were screen-positive for development of pre-eclampsia using the NICE and FMF methods, respectively. Of those who were screen-positive by NICE recommendations, aspirin was not prescribed in 25%. Across the three groups, namely, pregnancies without pre-eclampsia, term pre-eclampsia and preterm pre-eclampsia there was a statistically significant trend in rates of emergency caesarean (respectively 21%, 43% and 71.4%; P < 0.001), admission to neonatal intensive care unit (NICU) (5.9%, 9.4%, 41%; P < 0.001) and length of stay in NICU. The FMF algorithm was associated with seven fewer cases of preterm pre-eclampsia, cost saving of £9.06 and QALY gain of 0.00006/pregnancy screened. CONCLUSIONS: Using a conservative approach, application of the FMF algorithm achieved clinical benefit and an economic cost saving.

BACKGROUND: Caesarean section (CS) is widely perceived as protective against obstetric brachial plexus injury (BPI), but few studies acknowledge the factors associated with such injury. The objectives of this study were therefore to aggregate cases of BPI after CS, and to illuminate risk factors for BPI. METHODS: Pubmed Central, EMBASE and MEDLINE databases were searched using free text: ("brachial plexus injury" or "brachial plexus injuries" or "brachial plexus palsy" or "brachial plexus palsies" or "Erb's palsy" or "Erb's palsies" or "brachial plexus birth injury" or "brachial plexus birth palsy") and ("caesarean" or "cesarean" or "Zavanelli" or "cesarian" or "caesarian" or "shoulder dystocia"). Studies with clinical details of BPI after CS were included. Studies were assessed using the National Institutes for Healthy Study Quality Assessment Tool for Case Series, Cohort and Case-Control Studies. MAIN RESULTS: 39 studies were eligible. 299 infants sustained BPI after CS. 53% of cases with BPI after CS had risk factors for likely challenging handling/manipulation of the fetus prior to delivery, in the presence of considerable maternal or fetal concerns, and/or in the presence of poor access due to obesity or adhesions. CONCLUSIONS: In the presence of factors that would predispose to a challenging delivery, it is difficult to justify that BPI could occur due to in-utero, antepartum events alone. Surgeons should exercise care when operating on women with these risk factors.

OBJECTIVE: We aimed to determine foetal losses for DCDA and MCDA twins following transabdominal CVS or amniocentesis performed <22+0 weeks. METHODS: Retrospective cohort study conducted in the UK and Belgium 01/01/00-01/06/20. Cases with unknown chorionicity, monochorionic complications or complex procedures were excluded. Uncomplicated DCDA and MCDA twins without invasive procedures were identified as controls. We reported foetal losses <24+0 weeks and losses of genetically and structurally normal foetuses. RESULTS: Outcomes were compared for DCDA foetuses; 258 after CVS with 3406 controls, 406 after amniocentesis with 3390 controls plus MCDA foetuses, 98 after CVS with 1124 controls, and 160 after amniocentesis with 1122 controls. There were more losses <24+0 weeks with both procedures in DCDA (CVS RR 5.54 95% CI 3.38-9.08, amniocentesis RR 2.36 95% CI 1.22-4.56) and MCDA twins (CVS RR 5.14 95% CI 2.51-10.54, amniocentesis RR 7.01 95% CI 3.86-12.74). Losses of normal foetuses were comparable to controls (DCDA CVS RR 0.39 95% CI 0.05-2.83, DCDA amniocentesis RR 1.16 95% CI 0.42-3.22, MCDA CVS RR 2.3 95% CI 0.71-7.56, and MCDA amniocentesis RR 1.93 95% CI 0.59-6.38). CONCLUSIONS: This study indicates increased foetal losses for DCDA and MCDA twins following CVS and amniocentesis with uncertain risk to normal foetuses.

OBJECTIVE: To examine the antenatal imaging features, intrapartum findings and early postpartum course of pregnancies with trisomy 21 (T21) at a tertiary hospital in the United Kingdom. METHODS: Women with pregnancies diagnosed with T21 on antenatal or post-mortem/postnatal karyotyping, from February 2010-2020. Outcome measures included antenatal imaging findings, fetal growth restriction (FGR), birthweight, mode of delivery and early neonatal outcomes. RESULTS: 76 women were included. There were six intrauterine deaths and 70 livebirths. Thirty-eight (50%) had an antenatal diagnosis and twenty-five (33%) had a suspected diagnosis but declined further testing. The diagnosis was unanticipated in 13 (17%). Cardiac anomalies (35.5%) were the most common antenatal anomaly. Doppler abnormalities were apparent in 48/73 (68%). Eighteen (25.7%) had antenatal FGR. The majority were delivered by Caesarean section, and 21.4% of babies weighed Assuntos

RESUMO
INTRODUCTION: Fetal growth restriction (FGR) is associated with poor perinatal outcomes. Screening and prevention tools for FGR, such as uterine artery Doppler imaging and aspirin, underperform in high-risk groups, compared with general antenatal populations. There is a paucity of sensitive screening tests for the early prediction of FGR in high-risk pregnancies. MATERIALS AND METHODS: This was a prospective observational study based in a dedicated antenatal hypertension clinic at a tertiary UK hospital. We assessed maternal demographic and central hemodynamic variables as predictors for FGR in a group of women at high risk for placental insufficiency due to chronic hypertension (n = 55) or a history of hypertension in a previous pregnancy (n = 71). Outcome variables were birthweight z-score as well as development of FGR (defined as birthweight below the 5th or 3rd centile). Maternal hemodynamics were assessed using a noninvasive transthoracic bioreactance monitor (Cheetah NICOM). RESULTS: The mean gestation at presentation was 13.6 (range: 8.5-19.5) weeks. Sixteen women delivered babies below the 5th centile. Ten of these were below the 3rd centile. Independent predictors of birthweight z-score were body surface area, peripheral vascular resistance and white ethnicity (R(2) = 0.26, p < 0.0001). Independent predictors of FGR were maternal height and cardiac output. The area under the receiver operator characteristic curve for prediction of FGR was 0.915 (95% CI 0.859-0.972) and 0.9079 (95% CI 0.823-0.990) for FGR below the 5th and 3rd centiles, respectively. CONCLUSION: In women with chronic hypertension or a history of hypertension in a previous pregnancy, maternal size and cardiac output at booking provide a sensitive screening tool for FGR.

BACKGROUND: Pregnancies in women with sickle cell disease (SCD) are known to have high rates of maternal and fetal mortality and morbidity. Given these pregnancy-associated problems for women with SCD, advice both about pregnancy planning and about effective contraception are of paramount importance. This study sought to discover the contraception methods used by women with SCD, what complications women with SCD encounter with contraception, and their experiences of pre-pregnancy counselling and pregnancy planning, and how such issues may have changed over the past two decades. METHOD: The study was a multicentre, interview-based, cross-sectional study. Interviews were carried out with 102 women with SCD, in north and central London during 2010, concerning their current and previous contraceptive use, their pregnancy history, their menstrual history, and the advice they received concerning pregnancy planning and contraception. Patient information was anonymised and ethical approval was obtained. These data were compared with data from a similar study undertaken in 1993. RESULTS: There were significant differences in a number of key areas: the number of unplanned pregnancies decreased from 64% in 1993 to 53% in 2010. The number of women with SCD who were advised not to become pregnant also fell, from 36% to 15%. The use of combined oral contraceptive pills declined, from 45% of the women in 1993 to 31% in 2010. Conversely the use of depot medroxyprogesterone acetate contraception (DMPA) and the levonorgestrel intrauterine system (LNG-IUS) both increased. CONCLUSIONS: Significant changes in the contraceptive methods used by women with SCD are demonstrated in the London population. LNG-IUS use in SCD has not been investigated before. There has been an encouraging decrease in the number of women with SCD who are advised not to become pregnant, perhaps reflecting an improvement in their overall health. Although the number of unplanned pregnancies has fallen, it remains high - emphasising the continuing need for women with SCD to have access to informed advice about pregnancy-associated issues and contraception.

A 46-year-old woman presented to the emergency gynaecology unit at the Royal Free Hospital, London, with lower abdominal pain and offensive per vagina discharge. These symptoms developed following a recent uterine artery embolisation around 3 weeks earlier at the same hospital. After initial treatment with antibiotics, this patient re-presented with a fibroid which had prolapsed through the cervix, resulting in pain, distress and more profuse vaginal discharge. This necrotic fibroid was morcellated and removed in theatre. She made an uneventful recovery and was able to go home the following day.

A 27-year-old woman with a positive urinary-pregnancy test, complaining of slight vaginal bleeding and some diffuse lower abdominal pain, presented to the emergency gynaecology unit at the Royal Free Hospital. Her initial ultrasound scan was inconclusive, and so serial serum beta human chorionic gonadotropin (hCG) blood tests were carried out. These demonstrated a suboptimal increase. A second transvaginal ultrasound (TVUS) was therefore performed, which showed a live cervical ectopic pregnancy. The patient, who remained haemodynamically stable, was admitted. She was treated with intramuscular methotrexate. She was given a second dose of methotrexate after 1 week, since her beta hCG levels did not demonstrate a satisfactory fall. A rapid decrease in serum hCG was then observed and the patient was then discharged. An outpatient TVUS was normal. The patient remained well throughout her treatment, never suffered any profuse vaginal bleeding, and thus surgical intervention was avoided.
