Multi-institutional and multi-disciplinary care: A successfully managed aortic dissection in the third trimester of pregnancy

Multi-disciplinary collaborative care for pregnant women with complex and emergent conditions is essential. Logistical planning, clear communication and human factor awareness are all non-clinical skills which need to be utilised in order to maximise outcomes. We describe the case of a proximal aortic dissection in the late third trimester of pregnancy diagnosed in a peripheral hospital that was transferred to a cardiothoracic centre for successful operative management 160 km away. This required the time-sensitive mobilisation and liaison of a receiving cardiothoracic, anaesthesiology and perfusionist team in conjunction with obstetric and midwifery support from an affiliated maternity hospital, as well as the national neonatal transport team. We emphasise the importance of multidisciplinary team management in complex cases and how imperative good inter-disciplinary communication is to ensure safe inter-hospital transfer.

Non-Invasive Prenatal Testing (NIPT) - We Need a National Programme

Aims The provision of non-invasive prenatal testing (NIPT), a blood test screening for aneuploidy during pregnancy, varies widely internationally. In Ireland, NIPT is available privately, costing over €400. Gobal research on the patient perspective on NIPT shows a strong desire for the test to be provided for free. Attitudes towards NIPT amongst pregnant women in Ireland have not previously been studied. We assessed this in women attending maternity services in our unit. Methods This was a cross-sectional observational study involving a telephone survey. Women were asked about their prior knowledge of NIPT. Women with no prior knowledge were given information about NIPT and asked about their opinion of the test. Results One hundred and twelve (n=112) women participated. Of these, 60% (n=67) had not heard of NIPT, 86% (n=96) believe it should be freely available, and 80% (n=90) said they would avail of the test if it were free. Cost was the main prohibitive factor for those choosing not to have the test. All women wished to be more informed about NIPT. Conclusion Awareness of NIPT amongst women attending maternity services in Ireland may be low, but there is a desire for more information and a more equitable provision of the test.

Valsartan exposure in pregnancy with resultant anhydramnios and chronic kidney disease in a late preterm infant

In utero exposure to angiotensin II receptor blockers (ARBs) has fetotoxic effects including renal failure, oligohydramnios and lung hypoplasia. We present the case of a 24-year-old woman who presented to the maternity services in the 34th week of her first pregnancy. She was taking valsartan for hypertension. Ultrasound showed a structurally normal fetus with anhydramnios. The patient was admitted and valsartan was discontinued. She had spontaneous preterm delivery at 35 weeks' gestation of a baby girl. The baby's urine output was minimal in the first week of life and she was transferred to a paediatric hospital for specialist nephrology input. At 6 months of age, she requires ongoing nephrology follow-up and she remains on treatment for hypertension and anaemia. This case demonstrates the serious adverse effects resulting from ARB exposure in utero, and highlights the importance of avoiding fetotoxic medications in women of childbearing age.

Prediction of recurrent preterm delivery in asymptomatic women- an anxiety reducing measure?

Objectives

The QUiPP application is used to predict the risk of recurrent preterm birth (PTB) in asymptomatic high risk women with a previous PTB. Our study aims to evaluate the impact of the use of the QUiPP app on maternal anxiety levels.

Study design

A retrospective cohort study on asymptomatic pregnant women attending the Prevention of Preterm Birth Clinic in a busy tertiary unit. Women included in the study had a history of previous PTB. The study assessment occurred at approximately 4 weeks prior to the gestation of the earliest previous PTB and included measurement of cervical length and vaginal fetal fibronectin. Data was inputted into the QUiPP application, which in turn estimated risk of preterm delivery at specific intervals. Measured outcomes were gestation at delivery, time from risk assessment to delivery, infant birth weight, NICU admission and length of stay. In addition, maternal anxiety levels were retrospectively assessed using a questionnaire with a Likert scale.

Results

Seventy six women were included in the study. All women were asymptomatic for preterm labour at assessment. The mean gestation at the time of risk assessment was 27 weeks, the mean time from risk assessment to delivery was 72 days. Average gestation at time of delivery was 37 weeks (range 22-42 weeks). The preterm birth rate was 29% (n = 22).Seventy seven percent of women who delivered <37 weeks, and 80% who delivered <34 weeks were given QUiPP scores predicting a ≥5% chance of PTB within four weeks of their actual delivery date. Sixteen percent of infants were admitted to NICU (n = 12) with a mean length of stay of 21 days. All infants went home well with their parents.Eighty four percent of respondents to our questionnaire reported feeling anxious about their pregnancy prior to attending the clinic. After receiving a QUIPP score 90% said they felt reassured and 79% reported that the felt less anxious.

Conclusion

In asymptomatic women, the use of the QUiPP app helps to predict, prevent, and optimise PTB. This surveillance has a beneficial role for maternal mental well-being in that it reduces anxiety at a key time during a pregnancy.

Sister Mary Joseph nodule: an unusual site for endometrioid cancer metastasis

Sister Mary Joseph (SMJ) nodules are rare malignant metastatic umbilical nodules, indicating disseminated disease and associated with a poor prognosis. This is the case of an 80-year-old woman who presented with umbilical discomfort and an ulcerated umbilical nodule. She was noted to have a bulky uterus and vaginal bleeding. CT abdomen-pelvis showed an enlarged uterus and right-sided lymphadenopathy, extending from the groin to the para-aortic area. Upper and lower endoscopies were normal. Biopsy of the umbilical nodule revealed metastatic endometrioid adenocarcinoma grade 1-2 with the endometrium and the ovary suggested as potential primary sites. The patient had cytoreductive surgery including en bloc resection of the umbilical tumour. Final histology confirmed Stage IVb endometrioid adenocarcinoma of the uterus. This unusual case highlights the diagnostic challenges faced with the presentation of an umbilical nodule. Gynaecological malignancy should always be considered within the initial differential diagnosis of an SMJ nodule.

OC-12 - Peri operative venous thromboembolism prophylaxis in gynaecological cancer patients. A survey of current practice

INTRODUCTION

Gynaecological cancer is associated with some of the highest rates of venous thromboembolism (VTE) with some subtypes of ovarian cancer associated with rates as high as 20%. VTE prophylaxis is an important part of post-operative management in gynaecological cancer patient care. Despite the evidence base and guidelines recommending extended VTE prophylaxis for patients undergoing major cancer surgery, adherence to best practice guidelines has been found to be low.

AIM

The aim of this study is to assess gynaecological oncologist's awareness of the guidelines surrounding VTE prophylaxis for post-operative gynaecological cancer patients and to determine the type and duration of VTE prophylaxis implemented by gynaecological oncologists.

MATERIALS AND METHODS

The study used the European Society Gynaecology Oncology (ESGO) membership as the population studied. ESGO is a multidisciplinary, non-profit association, founded in 1983. ESGO consisit of more than 1800 professional of different specialities dealing with gynaecological oncology. The e mail address of 650 member were avilable on the ESGO website. We send a Survey Monkey link to the questionnaire by email to a total of 650 ESGO member whose email addresses were obtained from the ESGO directory. 205 e mails returned back as the email used was invalied, only 445 e mail successfully delivered. The survey remained open for 44 days. Results were analysed on Survey Monkey.

RESULTS

A 59.3% of respondents said that they decided upon appropriate VTE prophylaxis for a patient according to national/international best practice guidelines. A further 39.4% respondents said that they made their choice based upon clinical judgement. 59.8% of respondents said that they begin VTE prophylaxis pre-operatively for the high risk patients. 6.1% said that they begin prophylaxis in the operating theatre, 18.9% begin prophylaxis 6 hours post-operatively and 9.1% begin prophylaxis 12 hours post-operatively. The remaining respondents said that they begin VTE more than 24 hours post operatively 44.7% said that they prescribe VTE prophylaxis for 4 weeks. A further 15.9% said that they prescribe VTE prophylaxis for 6 weeks and 4.75% for longer than 6 weeks.

CONCLUSIONS

In conclusion, the adherence to current guidelines for VTE prophylaxis in the peri-operative period for gynaecological oncology patients is still poor. Awareness needs to be raised in order to decrease the morbidity/mortality of VTE in this high risk group of patients. The adoption of multidiscplinary approach to manage gynaecological cancer patients, which includes the involvment of thrombosis specialist, may reduce post operative VTE rates and improve cancer care.

Manipulating the Dietary Cation-Anion Difference via Drenching to Early-Lactation Dairy Cows Grazing Pasture

Diets offered to grazing dairy cows can vary considerably in their dietary cation-anion difference (DCAD) and are often well in excess of what has been considered optimal. The effects of a range of DCAD on the health and production of pasture-based dairy cows in early lactation was examined in a randomized block design. Four groups of 8 cows were offered a generous allowance of pasture (45 +/- 6 kg/d of dry matter (DM) per cow) for 35 d and achieved mean pasture intakes of approximately 17 kg/d of DM per cow. Cows were drenched twice daily with varying combinations of mineral compounds to alter the DCAD. Dietary cation-anion difference ranged from +23 to +88 mEq/100 g of DM. A linear increase in blood pH and HCO(3)(-) concentration and blood base excess, and a curvilinear increase in the pH of urine with increasing DCAD indicated a nonrespiratory effect of DCAD on metabolic acid-base balance. Plasma concentrations of Mg, K, and Cl declined as DCAD increased, whereas Na concentration increased. Urinary excretion of Ca decreased linearly as DCAD increased, although the data suggest that the decline may be curvilinear. These results in conjunction with the increased concentrations of ionized Ca suggest that intestinal absorption of Ca or bone resorption, or both, increased as DCAD declined. Dry matter intake, as measured using indigestible markers, was not significantly affected by DCAD. However, the linear increase in the yield of linolenic acid, vaccenic acid, and cis-9, trans-11 conjugated linoleic acid in milk, as DCAD increased is consistent with a positive effect of DCAD on DM intake. Increasing DCAD did not significantly affect milk yield or milk protein, but the concentration and yield of milk fat linearly increased with increasing DCAD. The increased milk fat yield was predominantly a result of increased de novo synthesis in the mammary epithelial cells, although an increase in the yield of preformed fatty acids also occurred. Milk production results suggest that DCAD for optimal production on pasture diets may be higher than the +20 mEq/100 g of DM previously identified for total mixed rations.
