Abstract
BACKGROUND Acquired ESR1 mutations in estrogen receptor-positive (ER+) metastatic breast cancer (mBC) drive treatment resistance and tumor progression; new treatment strategies are needed. Lasofoxifene, a next-generation, oral, endocrine therapy and tissue-specific ER antagonist, provided preclinical antitumor activity, alone or combined with a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) in ESR1-mutated mBC. PATIENTS AND METHODS In the open-label, phase II, ELAINE 2 trial (NCT04432454), women with ESR1-mutated, ER+/human epidermal growth factor receptor 2-negative (HER2-) mBC who progressed on prior therapies (including CDK4/6i) received lasofoxifene 5 mg/day and abemaciclib 150 mg b.i.d until disease progression/toxicity. The primary endpoint was safety/tolerability. Secondary endpoints included progression-free survival (PFS), clinical benefit rate (CBR), and objective response rate (ORR). RESULTS Twenty-nine women (median age 60 years) participated; all but one were previously treated with a CDK4/6i (median duration 2 years). The lasofoxifene-abemaciclib combination was well tolerated with primarily grade 1/2 treatment-emergent adverse events (TEAEs), most commonly diarrhea, nausea, fatigue, and vomiting. One patient (with no prior CDK4/6i) discontinued treatment due to grade 2 diarrhea. No deaths occurred during the study. Median PFS was 56.0 weeks [95% confidence interval (CI) 31.9 weeks-not estimable; ∼13 months]; PFS rates at 6, 12, and 18 months were 76.1%, 56.1%, and 38.8%, respectively. CBR at 24 weeks was 65.5% (95% CI 47.3% to 80.1%). In 18 patients with measurable lesions, ORR was 55.6% (95% CI 33.7% to 75.4%). ESR1-mutant circulating tumor DNA (ctDNA) allele fraction decreased from baseline to week 4 in 21/26 (80.8%) patients. CONCLUSIONS Lasofoxifene plus abemaciclib had an acceptable safety profile, was well tolerated, and exhibited meaningful antitumor activity in women with ESR1-mutated, ER+/HER2- mBC after disease progression on prior CDK4/6i. Observed decreases in ESR1-mutant ctDNA with lasofoxifene concordant with clinical response suggest target engagement. If the ELAINE 2 findings are confirmed in the initiated, phase III, ELAINE 3 trial, these data could be practice-changing and help address a critical unmet need.

Abstract
AbstractStigma and social exclusion related to mental health are of substantial public health importance for Europe. As part of ROAMER (ROAdmap for MEntal health Research in Europe), we used systematic mapping techniques to describe the current state of research on stigma and social exclusion across Europe. Findings demonstrate growing interest in this field between 2007 and 2012. Most studies were descriptive (60%), focused on adults of working age (60%) and were performed in Northwest Europe—primarily in the UK (32%), Finland (8%), Sweden (8%) and Germany (7%). In terms of mental health characteristics, the largest proportion of studies investigated general mental health (20%), common mental disorders (16%), schizophrenia (16%) or depression (14%). There is a paucity of research looking at mechanisms to reduce stigma and promote social inclusion, or at factors that might promote resilience or protect against stigma/social exclusion across the life course. Evidence is also limited in relation to evaluations of interventions. Increasing incentives for cross-country research collaborations, especially with new EU Member States and collaboration across European professional organizations and disciplines, could improve understanding of the range of underpinning social and cultural factors which promote inclusion or contribute toward lower levels of stigma, especially during times of hardship.

Abstract
Abstract
Purpose: Prevention of chemotherapy-induced nausea and vomiting (CINV) is essential to preserve quality of life in cancer patients receiving highly emetogenic chemotherapy (HEC) such as doxorubicin-cyclophosphamide (AC) or cisplatin. Recently, new drugs (e.g. fosaprepitant and newer neurokinin 1 receptor antagonists [NK1RAs], rolapitant and netupitant) and updated guidelines for antiemetic use (e.g. adding olanzapine) have emerged. However, trends in real world antiemetic use are understudied.
Methods: We performed a retrospective study using the OptumLabs Data Warehouse (OLDW), which includes administrative claims for privately insured and Medicare Advantage enrollees in the U.S. We identified 34,236 patients age 18 years or older treated with either AC or cisplatin between January 2006 and June 2016. Data collected included baseline demographics (age, gender, census region and race), chemotherapy administered, and presence/absence of a central intravenous access device. Trends of anti-emetic use were presented overall and separately for 5-HT receptor antagonists (5HT3RAs) and NK1RAs.
Results: 23,030 patients (67.3%) received an anthracycline-based regimen (AC with or without docetaxel or paclitaxel), and 11,206 (32.7%) patients received cisplatin. Approximately two thirds of patients were female (n= 23,392). Dexamethasone use was stable over the decade (used by 85-90% in all years). Use of 5HT3RAs, primarily palonosetron and ondansetron, occurred in at least 95% of patients in all study years, consistent with guideline recommendations. NK1RAs were underutilized early on compared with guideline recommendations, but use increased to approximately 80% in the most recently evaluated year. Fosaprepitant use rose precipitously starting in 2009, preceding a sharp fall in aprepitant use beginning in 2011. The use of olanzapine, rolapitant and netupitant was minimal throughout the study period.
Conclusions: Dexamethasone and 5-HT3RAs were used in the vast majority of patients receiving HEC, in accordance with guideline recommendations. Less compliance with guidelines was seen with NK1RA use.

Abstract
INTRODUCTION One in eight paediatric primary care presentations is for a musculoskeletal (MSK) disorder. These patients are frequently referred to paediatric orthopaedic surgeons; however, up to 50% of referrals are for normal variants. This results in excessive wait-times and impedes access for urgent surgical cases. Adult MSK medicine has successfully utilised advanced practice physiotherapists (APP) managing non-surgical candidates, with documented benefits both to patients and services. There is a gap in the literature with regard to APP in paediatric orthopaedics. AIM In this review, we investigate demands on paediatric orthopaedic services, examine the literature regarding APP in paediatric orthopaedics and explore the value the role has to offer current outpatient services. RESULTS Paediatric orthopaedic services are under-resourced with concurrent long wait times. Approximately 50% of referrals are for normal variants, which do not require specialist intervention. Poor musculoskeletal examination skills and low diagnostic confidence amongst primary care physicians have been identified as a cause of inappropriate referrals. APP clinics for normal variants have reported independent management rate and discharge rates of 95% and marked reduction in patient wait times. CONCLUSION There is limited evidence to support the APP in paediatric orthopaedics. Further studies are needed investigating diagnostic agreement, patient/stakeholder satisfaction, patient outcomes and economic evaluation. Paediatric orthopaedics is in crisis as to how to effectively manage the overwhelming volume of referrals. Innovative multidisciplinary solutions are required so that the onus is not solely on physicians to provide all services. The APP in paediatric orthopaedics may be part of the solution.

Abstract
BACKGROUND Proton therapy (PT) is a radiotherapy treatment modality that uses protons, rather than conventional photons. PT is often used in paediatric oncology due to its reported capability to reduce acute and late adverse treatment effects. As PT is unavailable in Ireland, patients are referred abroad for treatment. AIMS To: (1) produce a descriptive study of Irish children referred abroad for PT, and (2) discuss the case for PT in general. METHODS A retrospective review of all children referred for PT before October 2015 was performed. Information was gathered regarding demographics, diagnosis, referral timeline, adverse effects attributable to PT, current status and cost. A review of the relevant literature was performed. RESULTS Seventeen children treated in Ireland have been referred abroad for PT. The largest number was in the 0-4 year old group. At initial diagnosis the median age was 4.8 years. The average cost per child was €37,312. Two patients suffered disease relapse. Four have encountered PT-related adverse effects. CONCLUSION Despite the fact that >100,000 patients worldwide have been treated with PT, the level of published evidence to support superiority over conventional treatment remains low. It is debated that randomised control trials in this area would be inconsistent with the principle of clinical equipoise. In contrast, there is a call for level 1 evidence to justify drastic changes in patient care, particularly in light of recent reports of unexpected toxicities. In time, careful evaluation, follow-up and clinical trials will likely support the preferential use of PT in children.

Abstract
Abstract
Background:
Pregnancy associated breast cancer (PABC) is defined as breast cancer (BC) diagnosed during pregnancy or during the year after delivery. Whether PABC is associated with inferior outcomes compared to non-PABC is uncertain. Data suggests characteristics and outcomes of BC diagnosed during pregnancy and BC diagnosed within the year after delivery may differ. However, most previous research has not separated BC cases diagnosed during pregnancy from those diagnosed within the year after delivery.
Methods:
We performed a single institution retrospective cohort study of women diagnosed at the Johns Hopkins Hospital with PABC between 1985-2014 and matched controls. Women with BC diagnosed during pregnancy and BC diagnosed during the year after delivery formed two separate case groups. Controls were matched 2:1 to each of the cases by time period of diagnosis, age (+/- 5 years) and extent of disease at diagnosis. Clinicopathologic features, treatment and outcomes were compared between each case group and its respective controls. Univariate Cox modeling stratified by matching set was used to compare time to relapse between cases and their matched controls.
Results:
Of 140 PABC cases identified, BC was diagnosed during pregnancy in 65 and during the year after delivery in 75. 135 controls were matched to the cases diagnosed during pregnancy and 145 controls were matched to the cases diagnosed during the year after delivery. Compared to their controls, cases diagnosed after delivery were more likely to have grade 3 tumors (81% versus 60%) and less likely to be hormone receptor (HR)-positive (62% versus 82%). Similarly, compared to their controls, cases who were pregnant at diagnosis were more likely to have grade 3 tumors (77% versus 57%) and less likely to be HR-positive (54% versus 75%). The frequency of HER2-positivity between cases diagnosed during pregnancy or during the year after delivery was similar to their respective control groups. A higher proportion of cases diagnosed during pregnancy underwent mastectomy than their controls, but this was not statistically significant (74% versus 67%). Most patients in both case groups and both control groups received chemotherapy. The proportions of patients in both case groups compared to their controls who received radiation were similar. Rates of relapse were high in the entire study population. There was a non-significant increased risk of relapse for both the cases diagnosed during pregnancy compared to their controls (HR 1.77, 95% CI 0.844-3.73, p 0.13) and for the cases diagnosed after delivery compared to their controls (HR 1.51, 95% CI 0.70-3.24, p 0.30).
Conclusions:
In our study population, women diagnosed with BC during pregnancy or within the year after delivery were more likely to have high grade and HR-negative disease than controls matched for age, extent of disease and time period of diagnosis. Rates of recurrence were high among our young study population. Findings must be interpreted with caution due to small sample size, but suggest that rates of relapse were not significantly higher among the cases diagnosed during pregnancy or within the year after delivery compared to their controls.

The questionnaire return rate was 55.3% and genetic counselors from a broad range of clinical experience, genetic counseling training programs and geographic regions responded. There was striking variation in symbols used for recording routine medical information in a genetic family history (i.e., pregnancy, spontaneous abortion, termination of pregnancy). There was even less consensus in recording situations representing new reproductive technologies (i.e., artificial insemination by donor semen, donor ovum, surrogate motherhood). The results of this survey document the need for developing standardized nomenclature in recording genetic family histories as a quality assurance measure in the delivery of genetic services. Such standardization will reduce the chance of incorrect interpretation of patient and family medical and genetic information.

Abstract
The incidence of colic following swimming exercise (SC) in a racehorse population examined over 3 years was 0.08%. Following 167,977 swims, 136 cases were reported. Colic resolved spontaneously in 2 horses, medically in 129 or surgically in 5. In a separate study, 21 horses were subject to exploratory laparotomy for SC. Findings included non-strangulating displacements in 7 horses, strangulating displacements in 7, a combination of non-strangulating and strangulating displacements in 1, prominent gaseous intestinal distension in 5 and no abnormalities in 1 horse. A poor response to analgesia prompted surgery in all cases. Rectal palpation and/or abdominal ultrasound was performed in 16 of 21 cases and abnormalities were found in 14 of these. Of the 21 surgical cases, 20 (95.2%) survived to discharge and 18 (90%) raced postoperatively.

Abstract
We constrain parity-violating interactions to the surface of last scattering using spectra from the QUaD experiment's second and third seasons of observations by searching for a possible systematic rotation of the polarization directions of cosmic microwave background photons. We measure the rotation angle due to such a possible "cosmological birefringence" to be 0.55 degrees +/-0.82 degrees (random) +/-0.5 degrees (systematic) using QUaD's 100 and 150 GHz temperature-curl and gradient-curl spectra over the spectra over the multipole range 200<l<2000, consistent with null, and constrain Lorentz-violating interactions to <2 x 10;{-43} GeV (68% confidence limit). This is the best constraint to date on electrodynamic parity violation on cosmological scales.

Abstract
In this study, a flat plate flowcell was modified to provide a reactor system that could maintain anaerobic, cellulolytic biofilms while providing the data needed to carry out a chemical oxygen demand mass balance to determine the cellulose digestion rates. The results showed that biofilms could be observed to grow and develop on cellulose particle surfaces from both anaerobic digester leachate and rumen fluid inocula. The observations suggest that the architecture of rumen and leachate derived biofilms may be significantly different with rumen derived organisms forming stable, dense biofilms while the leachate derived organisms formed less tenacious surface attachments. This experiment has indicated the utility of flowcells in the study of anaerobic biofilms.

Abstract
The aim of this work was to compare the impact of inoculation density on the rate of cellulose hydrolysis by a rumen derived culture with that of a microbial enrichment from an organic waste anaerobic digester. The results showed a linear relationship between the mass of biomass at the start of the first order degradation phase (Xo) and the first order hydrolysis rate (r) for both rumen inoculated and leachate inoculated cellulose digestions and that the slopes of these relationships were not distinguishable. This suggested that differences in the microbial community, media and other environmental factors had a lesser impact on the hydrolysis rate compared to the effect of the number of cells in the system. This could be of great importance to industrial applications of anaerobic digestion technologies as it suggested that if cells densities in the waste treatment digesters could be boosted to match those seen in the rumen, then the rates of the cellulose hydrolysis would rise.

Abstract
AIMS The utility of fluorescence in situ hybridization (FISH) for detecting uncultured micro-organisms in environmental samples has been shown in numerous habitats. In this study a suite of three FISH probes for cellulolytic bacteria is described and their efficacy is demonstrated by quantifying the relative abundance of the target micro-organisms in a range of industrial biomass samples. METHODS AND RESULTS The probes were designed from data derived from an artificial landfill leachate reactor study and 16S rRNA gene databases. The original biomass sample proved to be well described by the three probes targeting a total of 51% of the bacterial (EUBMIX targeted) cells in quantitative FISH experiments. CONCLUSIONS Three probes were developed and applied to samples from a range of industrial digesters. The CSTG1244 probe, specific for organisms closely related to Clostridium stercorarium, were observed in the widest range of samples (7 of the 19 samples tested). The CTH216a FISH probe, specific for organisms closely related to Clostridium thermocellum, described the highest proportion of the bacterial population within any one sample (46% in an anaerobically digested sludge sample). Finally, the BCE216a probe, specific for organisms closely related to Bacteroides cellulosolvens, achieved the lowest level of hybridisation of the three probes tested. SIGNIFICANCE AND IMPACT OF THE STUDY This study demonstrates that the three groups of anaerobic cellulolytic micro-organisms were present in different bioreactors but at variable abundances ranging from low (where other organisms would have been responsible for cellulolysis) to high. We showed the potential of using group specific FISH probes and quantitative FISH in environmental studies. The utility of using newly designed FISH probes was demonstrated by their ability to detect and quantify the target bacterial groups in samples from a range of industrial wastewater digesters.

Abstract
AIM The aim of this report was to assess the effects of radiotherapy (RT) in children with abdominopelvic tumours in whom a biodegradable (Polyglactin 910) mesh had been inserted prior to commencement of radiotherapy. METHODS Retrospective analysis was carried out of four patients with abdominopelvic tumours who underwent radiotherapy between 2000 and 2002 as part of their management. RESULTS All children tolerated radiotherapy well with no evidence of acute or chronic radiation enteritis. One child developed prolonged postoperative ileus and a second child developed infective diarrhoea and fever, not related to radiation. CONCLUSION We have highlighted a good tolerance of radiotherapy in children following the insertion of a Polyglactin 910 mesh prior to starting radiation and would recommend further larger studies with longer follow-up to support this.

Abstract
PURPOSE Open, observational studies of intradetrusor injections of botulinum toxin for detrusor overactivity have reported beneficial effects. We tested the efficacy and safety of botulinum toxin B for the treatment of the overactive bladder in a randomized, double-blind, placebo controlled crossover trial. MATERIALS AND METHODS A total of 20 patients 18 to 80 years old with detrusor overactivity unresponsive to oral antimuscarinic agents participated in the study. They were injected with either placebo (20 ml normal saline) or botulinum toxin B (5,000 IU diluted up to 20 ml) intravesically in a day case setting. After 6 weeks the treatments were crossed over without washout in line with previous findings. The primary outcome was the paired difference in change in average voided volumes. Frequency, incontinence episodes and paired differences in quality of life measured by the King's Health Questionnaire were the secondary outcome measures. RESULTS The Wilcoxon signed ranks test was used to test the paired difference in change between treatment phases. Little carryover was noted in the second arm placebo and the placebo data from both arms were included in analysis. There were clinically statistically significant paired differences in the change in average voided volume, urinary frequency and episodes of incontinence between active treatment and placebo (average voided volume: 95% CI difference 16, 122; Z2.5; p = 0.012/weekly frequency: 95% CI -21, -1; Z2.1, p=0.033/weekly incontinence: 95% CI -26, -7; Z3.3; p = 0.001). There were similarly significant paired differences in the change in quality of life affecting 5 domains of the King's Health Questionnaire. CONCLUSIONS This double-blind, placebo controlled, crossover study provides evidence of the efficacy of botulinum toxin B in the treatment of overactive bladder. Autonomic side effects were observed in 4 patients. The short duration of action will presumably limit the use to patients who have experienced tachyphylaxis with botulinum toxin A.

Abstract
BACKGROUND Hepatitis C (HCV) is a common cause of morbidity among patients who attend general practitioners (GPs) in Ireland for methadone maintenance treatment. AIMS To describe the development and content of guidelines for the management of HCV among current or former opiate users in the Eastern Regional Health Authority area attending GPs for methadone treatment. METHODS The guidelines were produced in five stages: identification of key stakeholders; development of evidence-based draft guidelines; discussion of content; determination of 'Delphi'-facilitated consensus and review by a sample of GPs for whom the guidelines would be intended. RESULTS The guidelines contain advice for GPs on all aspects of care of patients at risk of HCV, including general and preventative care, care of other bloodborne and hepatotoxic viruses, and the factors to be considered and appropriate evaluation prior to referring a patient for assessment at a hepatology unit. CONCLUSIONS GPs have an important role to play in the care of patients at risk of, or infected with, HCV.

Abstract
An anaerobic landfill leachate bioreactor was operated with crystalline cellulose and sterile landfill leachate until a steady state was reached. Cellulose hydrolysis, acidogenesis, and methanogenesis were measured. Microorganisms attached to the cellulose surfaces were hypothesized to be the cellulose hydrolyzers. 16S rRNA gene clone libraries were prepared from this attached fraction and also from the mixed fraction (biomass associated with cellulose particles and in the planktonic phase). Both clone libraries were dominated by Firmicutes phylum sequences (100% of the attached library and 90% of the mixed library), and the majority fell into one of five lineages of the clostridia. Clone group 1 (most closely related to Clostridium stercorarium), clone group 2 (most closely related to Clostridium thermocellum), and clone group 5 (most closely related to Bacteroides cellulosolvens) comprised sequences in Clostridium group III. Clone group 3 sequences were in Clostridium group XIVa (most closely related to Clostridium sp. strain XB90). Clone group 4 sequences were affiliated with a deeply branching clostridial lineage peripherally associated with Clostridium group VI. This monophyletic group comprises a new Clostridium cluster, designated cluster VIa. Specific fluorescence in situ hybridization (FISH) probes for the five groups were designed and synthesized, and it was demonstrated in FISH experiments that bacteria targeted by the probes for clone groups 1, 2, 4, and 5 were very abundant on the surfaces of the cellulose particles and likely the key cellulolytic microorganisms in the landfill bioreactor. The FISH probe for clone group 3 targeted cells in the planktonic phase, and these organisms were hypothesized to be glucose fermenters.

Abstract
OBJECTIVE To determine whether real-time ultrasound measurement of multiple linear dimensions of the bladder could be used to estimate total bladder volumes of women in labour. AIM To create a simple reproducible formula using ultrasound techniques to help estimate total bladder volumes of women in labour. This may prevent unnecessary catheterisation and conversely, avoid failure to catheterise when indicated, thereby reducing the complications associated with catheterisation and bladder overdistension. DESIGN Prospective, observational study of women in labour. SETTING Delivery Suite, Obstetric Hospital, University College London Hospitals. POPULATION Forty-nine women in labour recommended for catheterisation by their attending midwives. METHOD A real-time ultrasound scanner was used to measure bladder diameters in two planes: transverse width and height, and sagittal width and height. A Foley's catheter was inserted and the bladder drained into a graduated bowl under sterile conditions. These values and urine volumes were recorded and a formula for detecting bladder volumes above 300 mL was developed using linear regression methods and the Bland-Altman limits of agreement. MAIN OUTCOME MEASURE Sensitivity and specificity of derived formulae in predicting bladder volume from ultrasound measurements. Correctly predicted volumes greater than 300 mL. RESULTS Among the 49 women, 36 were nulliparous and 13 were multiparous. All had full-term pregnancies with cephalic presentation and were in active labour with cervical dilatations ranging from 3 to 10 cm. There were no previous caesarean sections among the multiparous women. Thirty-nine women had epidural analgesia. Indications for catheterisation included a palpable bladder per abdomen, or the interval from last urine voided. The catheterised volumes ranged from 30 to 720 mL with a median of 150 mL. The new equation (0.68 x h x d x w) had a sensitivity of 77% (95% CI 46-95%) and specificity of 86% (95% CI 71-95%) for detecting bladder volumes greater than 300 mL. In order to ensure that about 95% of women in need of catheterisation are detected, the above equation was improved using the Bland-Altman limits of agreement. The sensitivity of this final equation (1.74 x h x d x w) was 100% (95% CI 75-100%) and the specificity dropped to 36% (95% CI 21-54%). CONCLUSION It is possible to use real-time ultrasound in estimation of total bladder volumes of women in labour. The implications are that all of those normally selected as being in need of catheterisation could be detected, while about a quarter of those women would avoid unnecessary catheterisation.

Abstract
OBJECTIVE To detect the expression and transcription pattern of MUC1 in benign and malignant disease, and in two widely studied cell lines, and to investigate the glycosylation of MUC-1 in bone metastasis of prostate cancer, as mucins have been implicated in the progression and behaviour of several cancers. MATERIALS AND METHODS RNA extracted from cell lines (DU145 and PC3), five samples of BPH and five samples of prostate cancer was reverse transcribed before amplification of MUC1-specific sequences by polymerase chain reaction. Paraffin-embedded sections were stained for glycosylated MUC1 and MUC1 core epitopes by HMFG1 and B27.29 antibodies, respectively. Steroid-treated cell lines were analysed by fluorescence-activated cell sorting, using the same antibodies. RESULTS MUC1, in an under-glycosylated form, was widely expressed in the prostate and in metastatic lesions. MUC1/Z and MUC1/Y RNA were differentially expressed in BPH and prostate cancer, with no detectable expression of splice variant mRNA. This is in contrast to prostate cancer cell line cells (PC3 and DU145), which express splice variant mRNA. CONCLUSIONS BPH, prostate cancer and metastatic prostate cancer all express high levels of under-glycosylated MUC1. This may explain the inability of previous studies to detect MUC1 in prostate tissue, as the antibody used was specific for a carbohydrate epitope which is not expressed on the under-glycosylated MUC1.

Abstract
There is an increasing demand for methods to objectively assess a surgeon's competence. The purpose of this study is to test two evaluation methods that assess a surgeon's skills in the removal of mandibular third molar teeth. One method uses an objective checklist scale by which twenty components of the operation are judged as correct or incorrect. The second method is a global rating scale, that scores different aspects of performance, such as respect for tissue, number of manoeuvres, knowledge of procedure and instrument handling. Using these two methods, assessors judged the removal of 22 mandibular third molar teeth by 17 different surgeons. Good inter-rater reliability was achieved using both scales. A greater preference was expressed for the global rating scale for assessment and for the objective checklist scale for guiding feedback in training. Scales such as these need to be developed for, and tested on, different surgical procedures in order that credible assessment of surgical skills can be obtained.

Abstract
Measurement of cerebral tissue saturation during obstructive sleep apnoea (OSA) may provide additional information to conventional peripheral oxygen saturation. Thirteen subjects with OSA (mean apnoea/hypopnoea index 65.7+/-27.9) were monitored using full polysomnography and monitoring of near-infrared cerebral tissue oxygenation index (TOI). One-thousand and thirty-six apnoeas and hypopnoeas were analysed, in terms of duration, sleep stage, arterial oxygen saturation (Sa,O2) dip, minimum Sa,O2, TOI dip and minimum TOI. Cerebral TOI is a measure of cerebral tissue saturation of haemoglobin with oxygen, calculated using near-infrared spatially resolved spectroscopy, which has been shown to have a high specificity for intracranial changes. Decreases in cerebral oxygenation were observed during apnoeas and hypopnoeas. Baseline TOI ranged from 50.1-73.0% and mean apnoea/hypopnoea related TOI dips ranged from 1.43-6.85%. Mean Sa,O2 dips varied from 3.8-21.7%. In regression analysis, factors significantly predicting the magnitude of the TOI dip were Sa,O2 dip, minimum Sa,O2, apnoea duration and rapid eye movement sleep stage. The effect of apnoea duration and sleep stage remained significant after Sa,O2 was included in the regression equation. Near-infrared spectroscopy provides a noninvasive technique for monitoring cerebral tissue saturation during obstructive sleep apnoea.

Abstract
A patient's observation led us to investigate whether drinking from a champagne flute required more cranio-cervical extension than drinking from other types of wine glasses. We measured the cranio-cervical extension required by normal volunteers to drink from four different types of glass. The mean [95% confidence intervals] extension from the neutral position required to drain each glass was: narrow flute 40 degrees [35-44]; wide flute 22 degrees [19-25]; wine glass 26 degrees [24-29]; champagne saucer 0 degree [-1-2]. Drinking from the narrow rimmed champagne flute required significantly more extension than the other types of glass (p < 0.001), and 73% of the total available cranio-cervical extension.

Abstract
Oestrogen action is mediated via specific receptors that act as ligand-activated transcription factors. A monoclonal antibody specific to the C-terminus of human oestrogen receptor beta has been characterized and the prevalence of expression of oestrogen receptor beta protein investigated in a well defined set of breast cancers. Reverse transcription-polymerase chain reaction analysis of RNA from tissue biopsies detected oestrogen receptor beta in all samples examined. The anti-oestrogen receptor beta antibody cross reacted specifically with both long (approximately 59 Kd) and short (approximately 53 Kd) forms of recombinant oestrogen receptor beta. Western blot analysis of breast tumours contained both forms of oestrogen receptor beta protein although in some samples lower molecular weight species (32--45 Kd) were identified. Fifty-one breast cancer biopsies were examined using immunohistochemistry; 41 (80%) were immunopositive for oestrogen receptor alpha, 48 (94%) were immunopositive for oestrogen receptor beta and 38 (74.5%) co-expressed both receptors. Expression of oestrogen receptor beta was exclusively nuclear and occurred in multiple cell types. There was no quantitative relationship between staining for the two ERs although in tumours in which both receptors were present immunoexpression of oestrogen receptor alpha was invariably more intense. The significance of oestrogen receptor beta protein expression in breast cancers to therapy remains to be determined but the availability of a well characterized antibody capable of detecting oestrogen receptor beta in archive material will facilitate the process.

Abstract
Differences are examined in assessment and self-assessment scores, in oral and maxillofacial surgery trainees and MSc postgraduates, following the surgical removal of lower third molar teeth. This study found evidence of a surprising and worrying over-rating of their own surgical skills by many trainees and postgraduates.

Abstract
OBJECTIVE Long-axis function is determined by the longitudinally oriented myocardial fibers. Postnatally, conventional M-mode is used to assess tricuspid and mitral valve ring movements in relation to the cardiac apex. During fetal life, this is precluded by variable fetal position. We assessed the feasibility of determining right and left ventricular long-axis function in the fetus. METHODS A prospective, pilot study. The four-chamber view obtained during routine fetal echocardiography was recorded in a cineloop to which B-mode guided M-mode echocardiography was applied using angular M-mode. This allowed retrospective and correct placement of the cursor line from cardiac apex to tricuspid or mitral valve rings. M-mode tracings of the valve ring movements in relation to the apex were derived from the originally stored loop. Data from 18 fetuses (17-29 weeks of gestation) were available for analysis. Total excursion of the valve rings was measured offline. A second cursor line was simultaneously placed in the left ventricular outflow tract during color flow mapping for timing purposes (n = 6). RESULTS Right and left ventricular long-axis recordings were obtained in 18 and 14 cases, respectively. Total right ventricular excursion was 5.2 mm (SD, 0.9 mm) (range, 3.9-7.2 mm). Total left ventricular free wall excursion was 4.5 mm (SD, 1.1 mm) (range, 3.0-6.8 mm). For paired data, the mean of differences (right ventricle-left ventricle) was 0.8 mm (95% confidence interval 0.5-1.2). The valve rings moved towards the apex during systole (shortening) and away from it during diastole (lengthening). Peak downward movement coincided with cessation of aortic flow and diastolic lengthening with flow through the atrioventricular valves. CONCLUSION Long-axis function in the fetus is feasible if M-mode angle correction is used. There was no clinically significant difference between tricuspid and mitral valve excursions. The pattern of atrioventricular valve movement is coordinate and similar to that of adults. Long-axis function offers a new avenue to study systolic and diastolic function in the fetus.

Abstract
OBJECTIVE To compare resting long axis echocardiography with adenosine thallium-201 emission tomography in detecting myocardial ischaemic abnormalities and surgical related risk in patients before peripheral vascular surgery. DESIGN A prospective and blinded pre-operative examination of resting left ventricular minor and long axes and myocardial perfusion during adenosine vasodilation using thallium-201 emission tomography. SETTING A tertiary referral centre for cardiac and vascular disease equipped with invasive, non-invasive and surgical facilities. SUBJECTS 65 patients (40 male) with significant peripheral vascular disease, mean age 63+/-10 (S.D.) years, and 21 normal subjects of similar age. RESULTS Thallium-201 myocardial perfusion tomography was abnormal in 50/65 patients; 27 had fixed, 23 reversible abnormalities (19 of whom had both). Long axis was considered abnormal if one or more of two systolic long axis disturbances, reduced extent of total excursion <1 cm at any of the three (left, septal and posterior left ventricular) sites or prolonged shortening >1 mm after A2, and two diastolic abnormalities, delayed onset of lengthening >80 ms after A2 or reduced peak lengthening velocity <4.5 cm/s, was present. Long axis score (maximum 12) was based on the presence or absence of these four disturbances at each of the three sites. Myocardial perfusion imaging with thallium-201 classified the patients into three different groups according to their liability to low, moderate or high surgical risk (summed stress perfusion score of 36). Thirteen of 50 patients were identified as subjects at high surgical risk, with a perfusion score of 22/36 and below. Twelve of these demonstrated significantly greater impairment of systolic and diastolic long axis function, compared to those at low surgical risk, with a total long axis echo score of 6/12 or more. Seventeen of 18 patients identified as being at low surgical risk, with a perfusion score of 32/36 and above, had total long axis score of less than 6/12. The remaining 19 moderate risk patients had a wide range of long axis scores. In the 65 patients studied there were two post-operative deaths, one post-discharge death due to cerebrovascular accident, and one due to renal failure. CONCLUSION The combination of both systolic and diastolic long axis disturbances in patients with peripheral vascular disease can be used to predict the thallium assessment of surgical risk. Long axis echocardiography may thus have value as a screening test before non-cardiac surgery as well as providing a means of monitoring myocardial perfusion.

Abstract
Chronic heart failure (CHF) studies investigating the clinical, hemodynamic, and therapeutic importance of endothelin-1 (ET-1), atrial natriuretic peptide (ANP), and brain natriuretic peptide (BNP) are largely based on resting plasma levels, which may vary with prior exertion and postprandial status. This study investigated the importance of peak-exercise plasma levels of ET-1, ANP, and BNP in the assessment of left ventricular (LV) systolic function. Thirty-six male-patients ages 58 +/- 10 (mean +/- SD ) with NYHA class I-IV CHF due to coronary artery disease or idiopathic dilated cardiomyopathy were enrolled. LV systolic function was assessed by echocardiography and radionuclide ventriculography. Resting and peak cardiopulmonary exercise venous blood sampling and treadmill exercise testing were performed in the fasting state. Resting plasma levels of ET-1, ANP, and BNP were elevated compared with reference laboratory normal values. Exercise induced significant (p < 0.0001) increase in plasma levels of ET-1, ANP, and BNP. On univariate analysis peak-exercise plasma levels of ET-1, ANP, and BNP were more closely related to echocardiographically determined LV end-diastolic diameter and end-systolic diameter than their resting values. Multiple step-wise regression models identified resting and peak-exercise plasma levels of ET-1 and ANP but only the resting BNP as independent predictors of LV dimensions and systolic function. Peak exercise plasma levels of ANP and ET-1 are potentially more reliable and important than their resting levels as markers of LV systolic dysfunction and LV dimensions in patients with heart failure.

Abstract
OBJECTIVES To calculate socioeconomic and health status measures for the primary care groups in London and to examine the association between these measures and hospital admission rates. DESIGN Cross sectional study. SETTING 66 primary care groups in London, total list size 8.0 million people. MAIN OUTCOME MEASURES Elective and emergency standardised hospital admission ratios; standardised admission rates for diabetes and asthma. RESULTS Standardised hospital admission ratios varied from 74 to 116 for total admissions and from 50 to 124 for emergency admissions. Directly standardised admission rates for asthma varied from 152 to 801 per 100 000 (mean 364) and for diabetes from 235 to 1034 per 100 000 (mean 538). There were large differences in the mortality, socioeconomic, and general practice characteristics of the primary care groups. Hospital admission rates were significantly correlated with many of the measures of chronic illness and deprivation. The strongest correlations were with disability living allowance (R=0.64 for total admissions and R=0.62 for emergency admissions, P<0.0001). Practice characteristics were less strongly associated with hospital admission rates. CONCLUSIONS It is feasible to produce a range of socioeconomic, health status, and practice measures for primary care groups for use in needs assessment and in planning and monitoring health services. These measures show that primary care groups have highly variable patient and practice characteristics and that hospital admission rates are associated with chronic illness and deprivation. These variations will need to be taken into account when assessing performance.
