Abstract
OBJECTIVE A standard lateral neck dissection should yield at least 18 lymph nodes. The goal of the present study was to examine what factors might influence the number of lymph nodes retrieved during a neck dissection. METHODS This was a retrospective cohort study in a tertiary academic referral centre for head and neck oncology. Two hundred and nineteen consecutive neck dissections were examined. Age of the patient and primary site were recorded, along with tumour histology, previous radiotherapy and final nodal count. RESULTS The mean age was 62.2 ± 13.0 years. The most common primary site was the oral cavity (38.8 per cent). The mean number of lymph nodes was 30.63 ± 13.9. In total, 17.8 per cent had undergone previous radiotherapy. The mean number of lymph nodes was 33.26 ± 13.27 in patients with no previous radiation exposure and 18.47 ± 9.46 in those with previous radiation treatment. CONCLUSION Lymph node yield from a neck dissection is likely multi-factorial in nature. Previous radiotherapy, the only significant contributor, led to a mean reduction of lymph node yield from 33.3 to 18.5.

Abstract
There is growing evidence that smoking cessation (SC) improves outcomes following diagnosis of cancer. Notwithstanding adverse outcomes, a significant number of those diagnosed with cancer continue to smoke. Our objective was to document the SC services provided for patients with cancer by specialist adult cancer hospitals across Ireland, a country with a stated tobacco endgame goal. A cross-sectional survey based on recent national clinical guidelines was used to determine SC care delivery across eight adult cancer specialist hospitals, and one specialist radiotherapy centre. Qualtrics was used. The response rate was 88.9% with data reported from seven cancer hospitals and one specialist radiotherapy centre, all indicating they had some SC related provision (100%). Stop smoking medications were provided to cancer inpatients in two hospitals, at outpatients and attending day ward services in one hospital. Smokers with cancer were referred automatically to the SC service in two hospitals at diagnosis. While stop smoking medications were available 24 h a day in five hospitals, most did not stock all three (Nicotine Replacement Therapy, Bupropion, Varenicline). One hospital advised they had data on uptake of SC services for smokers with cancer but were unable to provide detail. There is considerable variation in SC information and services provided to cancer patients across adult cancer specialist centres in Ireland, reflecting the suboptimal practice of smoking cessation for patients with cancer found in the limited international audits. Such audits are essential to demonstrate service gaps and provide a baseline for service improvement.

Abstract
Background The benefits of smoking cessation (SC) for cancer patients are widely recognised. However, there has been a limited emphasis on SC in this context and it continues to be a challenge for cancer patients. As part of a larger feasibility study aiming to develop a structured SC pathway for cancer patients in Ireland, this qualitative study explored the SC practices, experiences and opinions of oncology healthcare professionals (HCPs). Methods Semi-structured interviews were conducted with 18 HCPs from lung, breast, cervical, head and neck and general oncology, across 4 specialist adult cancer hospitals in Ireland. Interview transcripts were analysed using thematic analysis. Results Four key themes emerged: (1) Frequently ask and advise but infrequently assist: most HCPs ask about smoking and many advise about available supports, but few refer patients to SC services. Where offered, referrals were to hospital SC services and/or nicotine replacement therapy was prescribed; no HCP prescribed varenicline or bupropion. Barriers included lack of time, ill-defined referral pathways and lack of knowledge. (2) Increased willingness but differing ability to quit: most patients were interested in quitting post diagnosis and had varying support needs, linked to cancer stage, social circumstances and stress levels. (3) Need for an integrated or parallel service: all HCPs suggested that a structured and defined referral pathway will facilitate SC. (4) Motivational counselling and pharmacotherapy combination: many HCPs suggested face to face as the best mode of intervention initially, with regular follow ups and ongoing support virtually, started pre-treatment, with an empathetic and empowering approach with provision of both motivational counselling and SC pharmacotherapy. Conclusions Smoking post cancer diagnosis has serious implications for cancer treatment and prognosis but is frequently overlooked. These findings will inform the design of a SC pathway for cancer patients. Key messages • Despite increased willingness to quit, there is inadequate and inconsistent SC support provision for cancer patients. • Tailored SC support should be an integral part of comprehensive cancer care.

Abstract
Abstract
Background and purpose
Hypertension is a major risk factor for coronary heart disease (CHD) development and progression, with pharmacological control of blood pressure reducing the risk of CHD events and death [1].
Treatment and control of blood pressure in CHD is suboptimal, with many patients failing to achieve guideline-directed targets [1,2]. This study aims to assess the relationship between antihypertensive medication regimens and blood pressure control in patients with hypertension and established coronary heart disease.
Methods
The iASPIRE study recently evaluated secondary prevention in an Irish cohort with coronary heart disease [2]. Based on a method used in a similar study [3], we calculated the average percentage daily dose of each prescribed antihypertensive agent. We then assessed the relationship between dose and number of antihypertensive agents with blood pressure control.
Results
540 (75.5%) of iASPIRE participants had an underlying diagnosis of hypertension, and at the study examination, 56% of these had a blood pressure ≥140/90 mmHg, while 83% had a blood pressure ≥130/80 mmHg. The median number of antihypertensive agents prescribed was 2 (IQR 1–2), with 88% of those with hypertension on at least one blood pressure medication. In participants with hypertension on treatment, the median percentage daily medication dose was 29% (IQR 14–50). After adjustment for age and sex, the addition of further antihypertensive medications increased the odds of achieving a blood pressure target of <130/80 mmHg (OR 1.3, 95% CI 1.07–1.69, p=0.012). The average percentage daily dose of each antihypertensive agent was lower in both participants with a medication-controlled blood pressure of <130/80 mmHg and <140/90 mmHg compared to those without blood pressure control (30% versus 37% p=0.006 and 33% versus 38% p=0.028 respectively).
Conclusion
Many patients with hypertension and coronary heart disease currently fail to achieve blood pressure control. This analysis found that an increasing number of antihypertensive medications but not increasing dose was associated with better blood pressure control. Combination therapy is superior to sequential monotherapy in the treatment of hypertension [1], and an approach that emphasises the initiation of several antihypertensive agents would likely lead to better blood pressure control in individuals with coronary heart disease.

Background and Purpose
Achieving risk factor (RF) control in patients with established coronary heart disease (CHD) reduces the risk of CHD events.(1) Cross-sectional studies have shown that the implementation of current prevention guidelines is poor, with most patients failing to meet recommended targets.(2,3) This study aims to identify demographic, psychosocial and clinical characteristics associated with the non-achievement of RF targets in a population with CHD.
Methods
In this post-hoc cross-sectional analysis, multivariable logistic regression identified characteristics significantly associated with poor RF control in participants of the iASPIRE study which recently assessed secondary CHD prevention in Ireland.
Results
An unhealthy diet (Odds Ratio [OR] 1.6, 95% CI 1.1-2.4, p=0.015), male sex (OR 1.8, 95% CI 1.2-2.8, p=0.007) and type of acute coronary syndrome event (OR 0.6, 95% CI 0.4-0.9, p=0.012) were associated with failure to achieve blood pressure recommendations. Female sex (OR 2.3, 95% CI 1.4-3.8, p=0.002), lack of high-intensity statin (OR 2.4, 95% CI 1.5-3.8, p<0.001) and recurrent hospitalisation for CHD (OR 1.9, 95% CI 1.3-2.8, p=0.001) were associated with poor LDL-C control. Decreasing age (OR 0.9, 95% CI 0.9-1.0, p=0.018), marriage (OR 4.3, 95% CI 1.5-12.1, p=0.007) and insulin use (OR 9.7, 95% CI 1.9-50.4, p=0.007) were associated with a HbA1c of ≥53mmol/mol. The absence of a longstanding illness or disability and decreasing resting heart rate were associated with composite RF control.
Conclusion
Several demographic, psychosocial and clinical characteristics are associated with achieving guideline-recommended RF targets. These findings will support the development of targeted solutions that will improve guideline implementation and the practice of CHD prevention in a high-risk population.

Background and Purpose
The reduction of low-density lipoprotein cholesterol (LDL-C) in patients with established coronary heart disease (CHD) reduces the risk of atherosclerotic cardiovascular disease (ASCVD) events.(1) Many CHD patients fail to achieve guideline-recommended LDL-C targets without prohibitively expensive proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9 inhibitors).(2, 3, 4) This study aims to assess the impact that bempedoic acid may have on PCSK9 inhibitor eligibility in a population with CHD and ascertain whether its universal adoption would lead to overall cost-savings and a cost-effective reduction in ASCVD events.
Methods and Results
This retrospective analysis included 635 participants from the iASPIRE study, which recently assessed secondary prevention in an Irish cohort of CHD patients. We applied the 2019 ESC/EAS dyslipidaemia guideline LDL-C target of <1.4mmol/L and simulated the average treatment effect of improved lipid-lowering therapy with statins, ezetimibe and bempedoic acid. 86.3% of iASPIRE participants did not have LDL-C control and qualified for treatment intensification. Optimisation of statin therapy would allow 24.4% of patients to achieve their LDL-C goal, while the addition of ezetimibe would improve this to 55.7% leaving 44.3% eligible for a PCSK9 inhibitor. Utilising bempedoic acid would further reduce the proportion eligible to 18.7%. Based on current market prices and the universal application of ESC/EAS recommendations,(1, 5) the adoption of bempedoic acid would reduce the annual treatment costs associated with PCSK9 inhibitor use by almost 50% and result in cost savings per prevented CVD event.
Conclusions
The vast majority of CHD patients currently fail to achieve the recommended LDL-C target in everyday clinical practice. Ezetimibe and optimised statin therapy would enable most patients to meet their LDL-C goal. Employing bempedoic acid in patients with poor LDL-C control would significantly reduce the requirement for PCSK9 inhibitors and lead to cost savings per prevented CVD event.

Abstract
Presentation We present the case of a 48-year-old man with nasal cellulitis and subsequent oro-naso-sino-orbital-cutaneous fistula from prolonged cocaine use. Diagnosis Initial laboratory investigations reported a raised white cell count (WBC) and C-Reactive Protein (CRP) and subsequently a positive atypical anti-neutrophil cytoplasm antibodies (ANCA) and positive anti-proteinase (PR3). Perihilar lung nodularity on chest imaging raised the possibility of a systemic autoimmune response. His urinalysis was positive for cocaine. Treatment He was commenced on Augmentin, Amphotericin B and Prednisolone. An obturator was created to manage the oro-nasal fistula. A subsequent naso-cutaneous defect was re-approximated. Daily nasal saline douche and abstinence of cocaine were recommended. Discussion Cocaine use in the community is rising and poses a challenge to multiple facets of our health care system.

Abstract
BACKGROUND Preterm birth impairs nephrogenesis, leading to a reduced nephron endowment which is inextricably linked to hypertension and chronic kidney disease in adults. The aim of this study was to compare nephron endowment between preterm infants to that of intrauterine fetuses at the same gestational age (GA) using a novel indirect ultrasound measurement of the renal parenchymal thickness. We hypothesized that extrauterine and intrauterine renal parenchymal thickness would differ based on altered renal growth environments. METHODS In this observational study, appropriately grown preterm infants (birth weight of between the 5th and 95th percentile) born <32 weeks, admitted to the neonatal department were eligible to participate. Renal parenchymal thickness of the infants was measured at 32- and 37-weeks postmenstrual age (PMA). These measurements were compared to the intrauterine renal parenchymal thickness of appropriately grown fetuses (control). RESULTS At 32-weeks PMA, the preterm infants had a significantly thinner renal parenchyma compared to fetuses at 32-weeks GA suggesting they had less nephrons, however by 37-weeks there was no significant difference in renal parenchymal thickness. CONCLUSIONS We propose that the differences in the extrauterine growth of the renal parenchyma in preterm infants may be due to a reduced number of nephrons and compensatory hyperfiltration. IMPACT This article provides insight into the effects of prematurity on nephrogenesis by comparing extrauterine renal parenchymal growth of born preterm infants to the ideal intrauterine fetal growth. Renal parenchyma thickness measurement using ultrasonography is a novel non-invasive measurement of renal development for the determination of nephron endowment. Differences in the renal parenchymal thickness of the preterm infants may be due to a deficit in nephron number and compensatory hyperfiltration.

Abstract
INTRODUCTION The study objectives were to develop standard charts for fetal renal artery blood flow to define normal ranges and to assess the reliability of the measurements. METHODS This prospective, longitudinal study reviewed 72 low-risk singleton pregnancies who had serial ultrasound examinations. Pulse wave Doppler was used to obtain the resistivity and pulsatility indices of the fetal renal arteries. Standard charts of the fetal renal arteries were created using mixed effects modelling and the intra- and interobserver reliability for the renal blood flow measurements was analysed. RESULTS Standard charts of the normal ranges of the renal artery resistive index (RI) and pulsatility index (PI) of the fetal renal arteries were created. The 3rd, 5th, 10th, 50th, 90th, 95th and 97th centiles were calculated. The intraclass correlation coefficient was acceptable for intraobserver reliability (RI = 0.66, PI = 0.88) and poor for interobserver reliability (RI = 0.11, PI = -0.56). CONCLUSIONS These novel charts demonstrate the change of the fetal renal artery blood flow during pregnancy. These may be used in clinical practice to detect variations from these normal ranges and be useful in future studies of kidney function projection.

Abstract
Background
Palliative inotropes are frequently utilized for symptom management in patients with end stage heart failure who are unable to undergo durable advanced heart failure therapies. With the advent of improved medical management and early intervention, palliative inotropes may allow for improved patient outcomes than seen previously. In this study, we aim to investigate the survival and outcomes of palliative inotrope therapy and its impacts on ischemic versus non-ischemic cardiomyopathy.
Methods
We retrospectively analyzed 220 patients with American Heart Association Stage D heart failure who were discharged with palliative inotrope therapy after January 1, 2010. Patients who underwent mechanical circulatory support (MCS) or those who underwent heart transplant were excluded. Those with a history of coronary artery disease, myocardial infarction, history of percutaneous intervention, or coronary artery bypass grafting were assigned to ischemic cardiomyopathy (ICM), while patients without these findings were assigned to non-ischemic cardiomyopathy (NICM). Statistical analysis was completed using Chi-Square and Student's t-tests, wherein p<0.05 was considered statistically significant.
Results
Of the 220 patients, 87 had NICM as opposed to 133 with ICM. Mean age was found to be higher among patients with ICM (70 [62–79]) compared to NICM (65 [55–72], p-value <0.01). No significant difference was seen in total days on inotrope therapy (p=0.6). While more patients in both groups were placed on milrinone as opposed to dobutamine, there was no difference between patients with ischemic and NICM (p=0.66 and 0.51 respectively). Although a greater number of patients with NICM had been lost to follow up, admitted to hospice, or expired at 2 years (p<0.01), survival at 3 months, 1 year, and 2 years showed no difference between both groups. No difference was seen in number of hospitalizations or clinic visits in one year. Both groups had similar complication rates with intravenous-access related PICC line infections and new arrhythmias. (See Table).
Conclusion
Despite more frequent use of durable mechanical support devices, many patients who are deemed unsuitable for invasive measures are treated with palliative inotrope therapy. We have found that there is no significant difference in survival, complications, and outcomes of patients on palliative inotropes among ischemic and NICM. These findings show the versatility of palliative inotrope therapy in end stage heart failure. Further studies with larger populations need to be evaluated.

Abstract
Anthropogenic climate change threatens corals globally and both high and low temperatures are known to induce coral bleaching. However, coral stress responses across wide thermal breadths remain understudied. Disentangling the role of symbiosis on the stress response in obligately symbiotic corals is challenging because this response is inherently coupled with nutritional stress. Here, we leverage aposymbiotic colonies of the facultatively symbiotic coral, Astrangia poculata, which lives naturally with and without its algal symbionts, to examine how broad thermal challenges influence coral hosts in the absence of symbiosis. A. poculata were collected from their northern range limit and thermally challenged in two independent 16-day common garden experiments (heat and cold challenge) and behavioral responses to food stimuli and genome-wide gene expression profiling (TagSeq) were performed. Both thermal challenges elicited significant reductions in polyp extension. However, there were five times as many differentially expressed genes (DEGs) under cold challenge compared to heat challenge. Despite an overall stronger response to cold challenge, there was significant overlap in DEGs between thermal challenges. We contrasted these responses to a previously identified module of genes associated with the environmental stress response (ESR) in tropical reef-building corals. Cold challenged corals exhibited a pattern consistent with more severe stressors while the heat challenge response was consistent with lower intensity stressors. Given that these responses were observed in aposymbiotic colonies, many genes previously implicated in ESRs in tropical symbiotic species may represent the coral host's stress response in or out of symbiosis.

Abstract
Abstract
Introduction
HPV infection is recognised as the main aetiological factor responsible for the increased incidence of oropharyngeal squamous cell carcinomas (OPSCC). Currently the epidemiology of oral HPV infection and OPSCC is poorly understood. In this study we aim to define the relationship between sexual behaviours and HPV-positive OPSCC.
Method
We performed a hospital-based, case-control study of 30 patients with HPV-positive and 30 patients with HPV-negative newly diagnosed oral cavity and OPSCC. The participants underwent questionnaire based interviews investigating variables such as age, gender, tobacco use, alcohol intake, and sexual behaviour.
Result
Subjects in the HPV-positive tumour subgroup had significantly less tobacco use then their HPV-negative counterparts (odds ratio, 0.92, 95% CI 0.9-1.17). A history of oral sexual activity was significantly more likely in the HPV-positive tumour subgroup (odds ratio, 5.23, 95% CI, 1.66-16.51), however this association did not remain significant when adjusted for age, gender, smoking and alcohol consumption. Similarly, there was significantly less alcohol consumption overall in the HPV-positive tumour subgroup (odds ratio, 0.107, 95% CI 0.96-1.01), but this association was no longer significant when adjusted for covariables.
Conclusion
Significantly less smoking was prevalent in patients with HPV-positive OPSCC. Although patients with HPV-positive tumours had less alcohol consumption and a stronger history of oral sexual activity overall, greater numbers are required in order to show a significant association. This further supports the known association between HPV-infection and OPSCC and the department of health's decision to commence vaccination of boys before the onset of sexual activity.
Take-home message
HPV-positive oropharyngeal cancer can develop without exposure to established risk factors such as tobacco use or excessive alcohol consumption. This change in pathogenesis should lead a change in how we prevent and manage the disease.

Abstract
BACKGROUND Tracheal stoma recurrence following oral cavity surgery is exceedingly rare. Although several different mechanisms for this have been described, the pathogenesis still remains uncertain. METHODS We present the case of a gentleman who presented 6-months following oral cavity SCC resection with a large fungating mass at his previous tracheostomy site, and also review the reported literature on this rare phenomenon. RESULTS Four weeks after diagnosis of his recurrence he underwent a total laryngectomy, wide-local skin excision and reconstruction with a pectoralis major pedicled flap. He recovered well initially following his operation, however unfortunately contracted nosocomial SARS-Cov2 and succumbed from respiratory complications during his post-operative recovery. CONCLUSION Stomal recurrence after temporary tracheostomy for oral cavity malignancies are very rare. Previously reported management of these can vary from surgical to palliative treatment. Methods to prevent these include delaying tracheostomy until after surgical resection, packing the pharynx during resection and adjuvant radiotherapy.

Abstract
AIMS/HYPOTHESIS Diabetes in pregnancy is thought to adversely affect the developing fetal kidneys. The rate of gestational diabetes is increasing globally with major consequences for future renal function. Very little is known about the impact of hyperglycaemia on the fetal renal parenchyma which contains the developing nephrons. The aim of this study was to measure the fetal renal parenchymal thickness and evaluate whether diabetes during pregnancy affects the growth of the fetal kidneys. METHODS This prospective, observational study used serial ultrasound measurements to evaluate the fetal renal parenchymal growth of 55 pregnancies with diabetes compared to 72 control pregnancies. Mixed effects modelling was used to analyse the data. RESULTS The renal parenchyma of fetuses from mothers with gestational diabetes was significantly thicker than those from the control group (LR Chisq = 4.8, df = 1, p = 0.029), however, the difference was proportional to the larger size of these fetuses. Fetuses of pregestational diabetics demonstrated no significant difference in renal parenchymal thickness compared to the control group even though they were also larger fetuses. Parenchymal growth slowed with increasing abdominal circumference in the pregestational diabetic group, suggesting an adverse effect on nephrogenesis, however this did not reach statistical significance. CONCLUSIONS/INTERPRETATION Our study provides unique data on how diabetes during pregnancy influences fetal kidney growth. Appropriate management of diabetic pregnancies may mitigate some of the adverse effects on the fetal kidneys. Increasing degrees of hyperglycaemia, as seen sometimes in pregestational diabetes, may affect nephrogenesis; however larger studies are needed.

Abstract
There are no publications reporting on scan duration and Doppler use during neonatal cranial ultrasound scans. We investigated current practice of neonatal cranial ultrasound at four large tertiary neonatal intensive care units in Australia. Cranial scans were prospectively recorded between March 2015 and November 2016. Variables, including total number of scans, scan duration and frequency and duration of colour and spectral Doppler mode, were extracted. A total of 196 scans formed the final cohort. The median (range) number of scans for each neonate was 1 (1-12). The median (range) overall total scan duration was 309 (119-801) s. Colour mode with or without spectral Doppler mode was used in approximately half of the cohort (106/196, 54%). Our findings comport with our hypotheses. Operators performing neonatal cranial scans in Australia have low overall scan durations. Although the use of Doppler mode during neonatal cranial scans is not standard practice in all neonatal intensive care units, it is used widely irrespective of the degree of prematurity or the presence of brain pathology. Further efforts are required to incorporate recommendations on scan duration and the routine use of Doppler mode during neonatal cranial scans. This is especially imperative given that the most vulnerable neonates with the greater neural tissue sensitivity are likely to be scanned more often.

Abstract
BACKGROUND Online programs targeting lifestyle have the potential to benefit brain health. We aimed to develop such a program for individuals with subjective cognitive decline (SCD). These individuals were reported to be at increased risk for dementia, and report both an intrinsic need for brain health information and motivation to participate in prevention strategies. Co-creation and user-evaluation benefits the adherence to and acceptance of online programs. Previously, we developed a prototype of the online program in co-creation with the users . OBJECTIVES We now aimed to evaluate the user-experiences of our online lifestyle program for brain health. DESIGN 30-day user test; multi-method. SETTING Participants were recruited in a memory clinic and (online) research registries in the Netherlands (Alzheimer Center Amsterdam) and Germany (Center for memory disorders, Cologne). PARTICIPANTS Individuals with SCD (N=137, 65±9y, 57% female). MEASUREMENTS We assessed user-experiences quantitatively with rating daily advices and usefulness, satisfaction and ease of use questionnaires as well as qualitatively using telephone interviews. RESULTS Quantitative data showed that daily advices were rated moderately useful (3.5 ±1.5, range 1-5 points). Participants (n=101, 78%) gave moderate ratings on the programs' usability (3.7±1.3, max 7), ease of learning (3.6±1.9) and satisfaction (4.0±1.5), and marginal ratings on the overall usability (63.7±19.0, max 100). Qualitative data collected during telephone interviews showed that participants highly appreciated the content of the program. They elaborated that lower ratings of the program were mainly due to technical issues that hindered a smooth walk through. Participants reported that the program increased awareness of lifestyle factors related to brain health. CONCLUSIONS Overall user-experience of the online lifestyle program was moderate to positive. Qualitative data showed that content was appreciated and that flawless, easy access technique is essential. The heterogeneity in ratings of program content and in program use highlights the need for personalization. These findings support the use of online self-applied lifestyle programs when aiming to reach large groups of motivated at-risk individuals for brain health promotion.

Abstract
OBJECTIVE The objective of this study was to develop new standard growth charts for fetal renal parenchymal thickness, length, and volume to define normal ranges for use in clinical practice and to assess the reliability of these measurements. METHODS This was a prospective, longitudinal study of 72 low-risk singleton pregnancies undergoing serial ultrasound examinations at least every four weeks. Multiple renal measurements were performed on both kidneys at each scan. The renal parenchymal thickness was measured in the mid-sagittal plane. Standard charts were developed and the intra and interobserver reliability for the renal measurements was analysed. RESULTS Standard charts were developed for fetal renal parenchymal thickness, length, and volume. CONCLUSION We present novel charts, which demonstrate the growth of the fetal renal parenchyma during pregnancy. They will be useful in clinical practice to identify any alterations from these normal ranges, which may be an important criterion for assisting prenatal diagnosis of renal pathologies and future studies in the prediction of kidney function.

Abstract
OBJECTIVES Ultrasound can lead to thermal and mechanical effects in interrogated tissues. This possibility suggests a potential risk during neonatal cranial ultrasound examinations. The aim of this study was to explore safety knowledge and training of neonatal cranial ultrasound among Australian operators who routinely perform these scans. METHODS An online survey was administered on biosafety and training in neonatal cranial ultrasound, targeting all relevant professionals who can perform neonatal cranial ultrasound examinations in Australia: namely, radiologists, neonatologists, sonographers, and pediatricians. The survey was conducted between November 2013 and May 2014. RESULTS A total of 282 responses were received. Twenty of 208 (10%) answered all ultrasound biosafety questions correctly, and 49 of 169 (29%) correctly defined the thermal index. Two-thirds (134 of 214 [63%]) of respondents failed to recognize that reducing the overall scanning time is the most effective method of reducing the total power exposure. Only 13% (31 of 237) indicated that a predetermined fixed period of training or that a specified minimum number of supervised scans was used during training. The reported number of supervised scans during training was highly variable. Almost half of the participants (82 of 181 [45%]) stated that they had received supervision for 10 to 50 scans (median, 20 scans). CONCLUSIONS There is a need to educate operators on biosafety issues and approaches to minimize power outputs and reduce the overall duration of cranial ultrasound scans. Development of standardized training requirements may be warranted.

Abstract
INTRODUCTION Disorders of fetal growth, such as intrauterine growth restriction (IUGR) and large for gestational age (LGA), have been found to have a profound effect on the development of the fetal kidney. Abnormal kidney development is associated with hypertension and chronic kidney disease later in life. This study will use a novel ultrasound measurement to assess the renal parenchymal growth and kidney arterial blood flow in the fetus to evaluate the development of the fetal kidneys and provide an indirect estimate of nephron number. Measurements in normally grown, IUGR and LGA fetuses will be compared to determine if changes in renal parenchymal growth can be detected in utero. METHODS AND ANALYSIS This longitudinal, prospective, observational study will be conducted over 12 months in the Ultrasound Department of the Townsville Hospital, Australia. The study will compare fetal renal parenchymal thickness (RPT) and renal artery Doppler flow between IUGR fetuses and appropriately grown fetuses, and LGA fetuses and appropriately grown fetuses between 16 and 40 weeks. The fetal RPT to renal volume ratio will also be compared, and correlations between RPT, renal parenchymal echogenicity, fetal Doppler indices and amniotic fluid levels will be analysed. ETHICS AND DISSEMINATION This study was approved by the Townsville Health District Human Research Ethics Committee. The study results will form part of a thesis and will be published in peer-reviewed journals and disseminated at international conferences.

Abstract
Evidence is increasingly showing that prematurity results in chronic kidney disease. We hypothesized that we could use ultrasound imaging to measure and monitor the growth of the renal parenchyma in premature neonates. We conducted a prospective, case-control study to compare renal parenchymal growth between neonates born prematurely and term neonates. The study patients underwent ultrasound assessment at 32 wk postmenstrual age (PMA) and 37 wk PMA. Term neonates (gestation >37 completed wk) admitted to the neonatal unit with minor neonatal conditions were recruited into the control group. Complete data sets were available in 91 premature neonates and during the same period, 56 term neonates were recruited as the control. The median birth weight (preterm babies) was 930 g (780-1220 g), and the mean gestational age was 27.0 wk (2.1 wk). Total renal volume (TRV) increased from 14.6 (4.3) cm3 to 20.5 (5.3) cm3 from 32 to 37 wk PMA. During the same period, the total renal parenchyma (TRP) thickness increased from 1.6 (0.3) cm to 1.8 (0.3) cm. At 37 wk PMA, ex-premature neonates have a significantly smaller total renal volume (20.5 [5.3] versus 25.9 [6.4] cm3; p < 0.001) and total renal parenchyma thickness (1.8 [0.3] versus 2.0 [0.2] cm; p = 0.015) compared with term (control) neonates. However, premature neonates at 37 wk PMA have a larger TRP:TRV ratio compared with term neonates (0.09 [0.02] versus 0.0 8 [0.02] cm-2; p < 0.001). Reduced nephron endowment as a result of prematurity may cause the remaining nephrons to undergo compensatory glomerulomegaly and we postulate this is the reason for the observed differences. Ultrasound imaging of the renal parenchyma shows promise in assessing the effects of prematurity on the developing kidney.

Abstract
PURPOSE To determine the role of ultrasound imaging in evaluating fetal kidney growth. METHODS MEDLINE, CINAHL and EMBASE databases were electronically searched for studies between 1996 and January 2017 and limited to English language. Studies were included if they reported on an ultrasound technique to assess fetal kidney growth and they were not a case report or case series. There was independent selection of studies by two reviewers in consensus with one other reviewer. Data were extracted by one reviewer in consensus with two other reviewers. RESULTS A total of 1785 articles were identified. The full text of 39 of these were assessed for eligibility for inclusion. Twenty-eight studies were then included in the review. Standard two dimensional (2D) fetal renal measurements are easy to perform, however, this review identified that most studies had some methodological limitations. The disadvantage with 2D and three dimensional (3D) fetal renal volumes are that they include the entire kidney and good reproducibility of 3D volumes has not yet been demonstrated. Currently there is limited research on fetal kidney growth in the setting of abnormal fetal growth. Research focussing directly on fetal kidney parenchyma and blood flow is scarce. CONCLUSIONS Some nomograms of 2D and 3D fetal kidney size and volume have been developed. Kidney length is the most popular single fetal kidney measurement; however, it does not seem to be a good indicator of growth. In IUGR fetuses, kidney length remained similar to appropriately grown fetuses whereas AP and TS dimensions were significantly decreased. New ultrasound techniques focusing on the parenchyma of the kidney and perfusion to the kidney should be explored as they may provide more meaningful information on kidney development in the fetus and future kidney function.

Abstract
Abstract
Background
The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals.
Methods
Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2).
Results
Data were collected on 4744 cholecystectomies from 165 hospitals. Increasing age, lower ASA fitness grade, biliary colic, the need for further imaging (magnetic retrograde cholangiopancreatography), endoscopic interventions (endoscopic retrograde cholangiopancreatography) and admission to a non-biliary centre significantly reduced the likelihood of an emergency cholecystectomy being performed. The multilevel model was used to calculate the probability of receiving an emergency cholecystectomy for a woman aged 40 years or over with an ASA grade of I or II and a BMI of at least 25·0 kg/m2, who presented with acute cholecystitis with an ultrasound scan showing a thick-walled gallbladder and a normal common bile duct. The mean predicted probability of receiving an emergency cholecystectomy was 0·52 (95 per cent c.i. 0·45 to 0·57). The predicted probabilities ranged from 0·02 to 0·95 across the 165 hospitals, demonstrating significant variation between hospitals.
Conclusion
Patients with similar characteristics presenting to different hospitals with acute gallbladder pathology do not receive comparable care.

Abstract
Nasopharyngeal cancer is unique among head and neck cancers. Despite definitive treatment, there is a high rate of recurrence, most commonly in the bone, lung or liver. Brain metastases and particularly, leptomeningeal carcinomatosis are extremely rare. We present a case of recurrent nasopharyngeal carcinoma with brain metastases and leptomeningeal carcinomatosis in the absence of local recurrence and systemic metastases.

Abstract
Low birth weight (LBW, <2500 g) infants have a reduced number of glomeruli and nephrons and, therefore, smaller kidneys. The purpose of this pilot study was to determine whether renal parenchymal thickness might be a better indicator of renal growth. We carried out a pilot study over 12 mo to determine whether renal parenchymal thickness could be used to detect differences in renal growth between LBW and normal birth weight (NBW, 2500-4500 g) infants. Thirty-eight term infants (12 LBW and 26 NBW) underwent renal ultrasound. Parenchymal thickness, length, transverse diameter and antero-posterior diameter were measured. Mean renal parenchymal thickness was significantly lower in LBW infants than in NBW infants. Renal parenchymal thickness was closely correlated with an increase in renal volume (r = 0.76, p < 0.0001). Renal parenchymal thickness is a single measurement that could potentially be a more useful and accurate approach to monitoring renal growth in growth-restricted infants than renal volume.

Abstract
BACKGROUND Several neuroimaging studies have investigated brain grey matter in people with body dysmorphic disorder (BDD), showing possible abnormalities in the limbic system, orbitofrontal cortex, caudate nuclei and temporal lobes. This study takes these findings forward by investigating white matter properties in BDD compared with controls using diffusion tensor imaging. It was hypothesized that the BDD sample would have widespread significantly reduced white matter connectivity as characterized by fractional anisotropy (FA). METHOD A total of 20 participants with BDD and 20 healthy controls matched on age, gender and handedness underwent diffusion tensor imaging. FA, a measure of water diffusion within a voxel, was compared between groups on a voxel-by-voxel basis across the brain using tract-based spatial statistics within the FSL package. RESULTS Results showed that, compared with healthy controls, BDD patients demonstrated significantly lower FA (p < 0.05) in most major white matter tracts throughout the brain, including in the superior longitudinal fasciculus, inferior fronto-occipital fasciculus and corpus callosum. Lower FA levels could be accounted for by increased radial diffusivity as characterized by eigenvalues 2 and 3. No area of higher FA was found in BDD. CONCLUSIONS This study provided the first evidence of compromised white matter integrity within BDD patients. This suggests that there are inefficient connections between different brain areas, which may explain the cognitive and emotion regulation deficits within BDD patients.

Abstract
BACKGROUND Aspergillus spp. are the leading cause of invasive fungal infection in lung transplant recipients. We investigated the relationship between the isolation of Aspergillus spp. from the respiratory tract of lung transplant recipients and their risk of mortality. METHODS A retrospective, observational cohort study of all patients who received lung allografts between January 1999 and May 2011 at a single UK centre was performed. The time from transplantation to death was analysed using Cox regression models. Isolation of Aspergillus spp. from the respiratory tract was included as a covariate in the Cox regression model. RESULTS Two hundred-thirteen patients were included. The median follow-up time was 5 years during which 102 patients (47.9%) died. Aspergillus was isolated from 74 (34.7%) patients. Twenty patients (27%) had Aspergillus isolated in the first 60 days post-transplant. Forty-one patients (55.4%) in the Aspergillus group and 61 patients (43.9%) in the non-Aspergillus group died during follow-up. A hazard ratio of 2.2 (95% CI 1.5-3.3; P < 0.001) for death following a positive Aspergillus sample was observed. CONCLUSION Isolation of Aspergillus spp. from patients following lung transplantation is associated with a significant increase in mortality. Novel preventative strategies are required to minimise the impact of Aspergillus in lung transplant recipients.

Abstract
Microscopical evaluation of tissues from a mature female cynomolgus monkey assigned to a 13-week oral toxicity study revealed nests of sebaceous cells within the mucosa of the distal oesophagus. The sebaceous cell nests showed normal differentiation from basally-oriented seboblasts to centrally-orientated mature sebocytes. No excretory ducts were found, but solitary or small groups of vacuolated sebocytes were present in the overlying normal, non-keratinized squamous epithelium. The finding of sebaceous cells, of presumed ectodermal origin, in the oesophageal mucosa, which is of endodermal origin, is of scientific interest. Different theories may explain the existence of this peculiarity, but sebaceous gland metaplasia is the most plausible. The mucosal change was thought to be unrelated to treatment and is the first case of sebaceous gland metaplasia reported in the oesophagus of a non-human primate.

Abstract
The prevalence of A, B and AB blood types and of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) infection was determined in cats in Ireland, in order to determine risk factors for blood taken for transfusion purposes. EDTA blood samples were available from 137 non-pedigree cats and 39 pedigree cats (91 females and 85 males, aged four months to 15.0 years) in the Dublin area of Ireland. Of the 176 EDTA blood samples obtained, 112 (from 92 healthy cats and 20 sick cats) were tested for the presence of both FIV antibodies and FeLV antigens. Blood typing was performed using an immunochromatographic cartridge (CHROM; Alvedia). Testing for FIV and FeLV was performed by ELISA (SNAP FIV/FeLV Combo Test; Idexx Laboratories). Of the 39 pedigree cats, the majority (38 [97.4 per cent]) was type A, and only one (2.6 per cent) was type B. Of the 137 non-pedigree cats, the majority (116 [84.7 per cent]) was type A, 20 (14.6 per cent) were type B, and one (0.7 per cent) was type AB. Of the 92 healthy cats tested, the prevalence of FIV and FeLV positivity was 4.35 and 1.09 per cent, respectively. None of the 20 sick cats tested was FIV-positive; two (10 per cent) of the 20 sick cats were FeLV-positive.

Abstract
Abstract
Purpose: To determine the frequency of breast cancer detection in women at increased risk due to a prior high-risk lesion.Materials and methods: An IRB approved retrospective review was performed of the records of 2184 breast MRIs starting from 1999, to identify patients who commenced screening breast MRI who had a history of a prior high risk lesion. Eighty-three women were identified who had a prior biopsy demonstrating a high-risk lesion such as atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH) or lobular carcinoma in situ (LCIS). History, imaging, and pathologic findings were reviewed.Results: Histologies of prior high-risk lesions in these 83 women were ADH in 24, LCIS in 54 and ALH in 5. The median length of MRI follow-up was four (range, 1-9) years. Biopsies were recommended based on MRI findings in 39 (47%) of 83 women, yielding cancer in seven (8%) women (four of whom also had benign biopsies), and benign findings only in 32 (39%) women. Six of the seven women who developed a breast cancer also had a family history of breast cancer. Histologic findings in these seven cancers were ductal carcinoma in situ (DCIS) in 4 (57%) and invasive cancer in three (43%). Invasive cancer histologies (n=3) were ductal in one and lobular in two; maximal histologic size was 2.0 cm. This large invasive cancer had a mammographic, sonographic, and palpable correlate, and was node-positive; the other cancers were identified by MRI only. Among these seven cancers, two (29%) were detected in screening year 1, two (29%) in screening year 2, two (29%) in screening year 3 and one in screening year 4 (14%). Three (43%) of the seven cancers were in the contralateral breast. In these 83 women, the likelihood of detecting cancer by MRI was higher in those with, rather than without, a family history of breast cancer (6/54=11% vs. 1/29=3%) and in women with prior LCIS rather than prior ADH (6/54=11% vs. 1/24=4%).Conclusion: Breast MRI detected cancer in 7 (8%) of 83 women with a prior high-risk lesion, six (86%) of whom also had a family history of breast cancer. Among these cancers, all were detected during the first four years of screening and less than half were invasive (43%). Further work with more patients is needed to determine the utility of breast MRI screening in women with specific prior high-risk lesions, with and without additional risk factors.

Abstract
BACKGROUND Current best practice for treating acute severe pain in children is to administer intravenous or intranasal opioid. Intranasal diamorphine offers less traumatic analgesia than the potentially difficult and distressing intravenous route. However, there has been no direct comparison of intranasal and intravenous diamorphine nor are there pharmacokinetic data for intranasal diamorphine in children. OBJECTIVE To compare plasma morphine concentration-time profiles following intranasal and intravenous diamorphine administration. DESIGN Observational. SETTING A&E department in a city-centre paediatric teaching hospital. PATIENTS Children, aged 3-13 years, with isolated limb fracture. INTERVENTIONS An intravenous catheter was sited and baseline blood taken. The first 12 children received intravenous diamorphine (0.1 mg/kg), and the subsequent 12 intranasal diamorphine (0.1 mg/kg) in 0.2 ml sterile water drops. Subsequent samples were taken at 2, 5, 10, 20, 30 and 60 min. MEASUREMENTS Plasma morphine radioimmunoassay. RESULTS Peak plasma morphine concentrations were higher (median 109 vs 36 nmol/l), and occurred earlier (median 2 vs 10 min), with greater area under the curve (3761 vs 1794 nmol/l/h) following intravenous compared to intranasal diamorphine (all p<0.001, Mann-Whitney U test). Higher plasma concentrations at 60 min (47 vs 32 nmol/l) were also observed following intravenous diamorphine (p = 0.01, Mann-Whitney U test). CONCLUSIONS Our evidence supports the wider use of diamorphine administration by nasal drops in children, as it shows that adequate plasma levels of morphine are usually achieved. However, we demonstrated significantly attenuated and delayed peak plasma morphine levels with lower levels at 1 h with intranasal compared with intravenous diamorphine.
