Abstract
The 7th National Audit Project of the Royal College of Anaesthetists studied peri-operative cardiac arrest in the UK, a topic of importance to patients, anaesthetists and surgeons. Here we report the results of the 12-month registry, from 16 June 2021 to 15 June 2022, focusing on epidemiology and clinical features. We reviewed 881 cases of peri-operative cardiac arrest, giving an incidence of 3 in 10,000 anaesthetics (95%CI 3.0-3.5 per 10,000). Incidence varied with patient and surgical factors. Compared with denominator survey activity, patients with cardiac arrest: included more males (56% vs. 42%); were older (median (IQR) age 60.5 (40.5-80.5) vs. 50.5 (30.5-70.5) y), although the age distribution was bimodal, with infants and patients aged > 66 y overrepresented; and were notably more comorbid (73% ASA physical status 3-5 vs. 27% ASA physical status 1-2). The surgical case-mix included more weekend (14% vs. 11%), out-of-hours (19% vs. 10%), non-elective (65% vs. 30%) and major/complex cases (60% vs. 28%). Cardiac arrest was most prevalent in orthopaedic trauma (12%), lower gastrointestinal surgery (10%), cardiac surgery (9%), vascular surgery (8%) and interventional cardiology (6%). Specialities with the highest proportion of cases relative to denominator activity were: cardiac surgery (9% vs. 1%); cardiology (8% vs. 1%); and vascular surgery (8% vs. 2%). The most common causes of cardiac arrest were: major haemorrhage (17%); bradyarrhythmia (9%); and cardiac ischaemia (7%). Patient factors were judged a key cause of cardiac arrest in 82% of cases, anaesthesia in 40% and surgery in 35%.

Abstract
The 7th National Audit Project of the Royal College of Anaesthetists studied peri-operative cardiac arrest in the UK, a topic of importance to patients, anaesthetists and surgeons. We report the results of the 12-month registry phase, from 16 June 2021 to 15 June 2022, focusing on management and outcomes. Among 881 cases of peri-operative cardiac arrest, the initial rhythm was non-shockable in 723 (82%) cases, most commonly pulseless electrical activity. There were 665 (75%) patients who survived the initial event and 384 (52%) who survived to hospital discharge. A favourable functional outcome (based on modified Rankin Scale score) was reported for 249 (88%) survivors. Outcomes varied according to arrest rhythm. The highest rates of survival were seen for bradycardic cardiac arrests with 111 (86%) patients surviving the initial event and 77 (60%) patients surviving the hospital episode. The lowest survival rates were seen for patients with pulseless electrical activity, with 312 (68%) surviving the initial episode and 156 (34%) surviving to hospital discharge. Survival to hospital discharge was worse in patients at the extremes of age with 76 (40%) patients aged > 75 y and 9 (45%) neonates surviving. Hospital survival was also associated with surgical priority, with 175 (88%) elective patients and 176 (37%) non-elective patients surviving to discharge. Outcomes varied with the cause of cardiac arrest, with lower initial survival rates for pulmonary embolism (5, 31%) and bone cement implantation syndrome (9, 45%), and hospital survival of < 25% for pulmonary embolism (0), septic shock (13, 24%) and significant hyperkalaemia (1, 20%). Overall care was rated good in 464 (53%) cases, and 18 (2%) cases had overall care rated as poor. Poor care elements were present in a further 245 (28%) cases. Care before cardiac arrest was the phase most frequently rated as poor (92, 11%) with elements of poor care identified in another 186 (21%) cases. These results describe the management and outcomes of peri-operative cardiac arrest in UK practice for the first time.

Abstract
Background Colonization continues in Australia, sustained through institutional and systemic racism. Targeted discrimination and intergenerational trauma have undermined the health and wellbeing of Australia’s Aboriginal and Torres Strait Islander population, leading to significantly poorer health status, social impoverishment and inequity resulting in the over-representation of Aboriginal people in Australian prisons. Despite adoption of the ‘equal treatment’ principle, on entering prison in Australia entitlements to the national universal healthcare system are revoked and Aboriginal people lose access to health services modelled on Aboriginal concepts of culturally safe healthcare available in the community. Incarcerated Aboriginal women experience poorer health outcomes than incarcerated non-Indigenous women and Aboriginal men, yet little is known about their experiences of accessing healthcare. We report the findings of the largest qualitative study with incarcerated Aboriginal women in New South Wales (NSW) Australia in over 15 years. Methods We employed a decolonizing research methodology, ‘community collaborative participatory action research’, involving consultation with Aboriginal communities prior to the study and establishment of a Project Advisory Group (PAG) of community expert Aboriginal women to guide the project. Forty-three semi-structured interviews were conducted in 2013 with Aboriginal women in urban and regional prisons in NSW. We applied a grounded theory approach for the data analysis with guidance from the PAG. Results Whilst Aboriginal women reported positive and negative experiences of prison healthcare, the custodial system created numerous barriers to accessing healthcare. Aboriginal women experienced institutional racism and discrimination in the form of not being listened to, stereotyping, and inequitable healthcare compared with non-Indigenous women in prison and the community. Conclusions ‘Equal treatment’ is an inappropriate strategy for providing equitable healthcare, which is required because incarcerated Aboriginal women experience significantly poorer health. Taking a decolonizing approach, we unpack and demonstrate the systems level changes needed to make health and justice agencies culturally relevant and safe. This requires further acknowledgment of the oppressive transgenerational effects of ongoing colonial policy, a true embracing of diversity of worldviews, and critically the integration of Aboriginal concepts of health at all organizational levels to uphold Aboriginal women’s rights to culturally safe healthcare in prison and the community.

Abstract
BACKGROUND Perinatal mental health (PMH) problems are a major public health concern because they may impair parenting ability which potentially has an immediate and long-term impact on the physical, cognitive and emotional health of the child. AIMS We evaluated a Perinatal Support Service (PSS) which supports positive attachment between mothers with PMH problems and their child, to evidence its impact on maternal mental health and maternal-infant interaction. METHOD Using a mixed-methods approach, anonymised pre- and post-service outcomes data from 123 clients, 14 interviews and a focus group discussion were analysed. RESULTS We found significant improvement in anxiety (t (55) = 6.96, p < 0.01, 95% CI [3.15, 5.70]), and depression (t (55) = 6.58, p < 0.01, 95% CI [3.03, 5.68]) on the HADS, and on the GAD-7 (t (12) = 4.541, p = 0.001, 95% CI [3.48, 9.90]) after the PSS. Anxiety post service (M = 9.08, SD = 4.96) was lower than baseline anxiety (M = 15.77, SD = 4.68). Receiving emotional and practical support contributed to improvements in mental health and mother-child interaction. CONCLUSION Given the paucity of PMH services in the UK, it is imperative that services such as the PSS continue to receive funding to address unmet PMH needs.

Abstract
OBJECTIVES Mycobacterium chimaera infection following cardiac surgery, due to contaminated cardiopulmonary bypass heater-cooler units, has been reported worldwide. However, the spectrum of clinical disease remains poorly understood. To address this, we report the clinical and laboratory features, treatment and outcome of the first 30 UK cases. METHODS Case note review was performed for cases identified retrospectively through outbreak investigations and prospectively through ongoing surveillance. Case definition was Mycobacterium chimaera detected in any clinical specimen, history of cardiothoracic surgery with cardiopulmonary bypass, and compatible clinical presentation. RESULTS Thirty patients were identified (28 with prosthetic material) exhibiting a spectrum of disease including prosthetic valve endocarditis (14/30), sternal wound infection (2/30), aortic graft infection (4/30) and disseminated (non-cardiac) disease (10/30). Patients presented a median of 14 months post surgery (maximum 5 years) most commonly complaining of fever and weight loss. Investigations frequently revealed lymphopenia, thrombocytopenia, liver cholestasis and non-necrotizing granulomatous inflammation. Diagnostic sensitivity for a single mycobacterial blood culture was 68% but increased if multiple samples were sent. In all, 27 patients started macrolide-based combination treatment and 14 had further surgery. To date, 18 patients have died (60%) a median of 30 months (interquartile range 20-39 months) after initial surgery. Survival analysis identified younger age, mitral valve surgery, mechanical valve replacement, higher serum sodium concentration and lower C-reactive protein as factors associated with better survival. CONCLUSIONS Mycobacterium chimaera infection following cardiac surgery is associated with a wide spectrum of disease. The diagnosis should be considered in all patients who develop an unexplained illness following cardiac surgery.

Abstract
BACKGROUND Total joint replacement of the 1st metatarso-phalangeal Joint (MTPJ) has been controversial as arthrodesis remains a good option for patients with end stage 1st MTPJ arthritis. We present a multi centre service evaluation of the ROTO-glide device METHODS: 33 ROTO-glide procedures were carried out in 30 patients across 7 sites within the UK. Exclusion criteria - hallux valgus and arthritis, age below 45 years and over 80 years, inflammatory joint disease. Patient assessed pre and post operatively with AOFAS and Oxford forefoot (MOXFQ) scores and plain radiographs. All patients carried out the same post operative protocol RESULTS: Average age at patients was 58.6 years (45-77). Follow up average was 16.9 months (12-29). Pre-op AOFAS scores average 41.4 (17-67) and post op average 76 (29-100) and the MOXFQ summary index decreased from an average of 43 (20-64) pre op to an average of 17 (0-51) post op. Average total range of motion pre operatively was 32° and post operatively was 61°. There were 2 post operative complications but no revisions were necessary. CONCLUSIONS The early results of this multi centre service evaluation of the ROTO-glide 1st MTPJ replacement support its continued use and evaluation of the prosthesis further.

Abstract
Mycobacterium bovis, the causative agent of bovine tuberculosis (bTB), is a multihost pathogen of public health and veterinary importance. We characterized the M. bovis isolated at the human-livestock-wildlife interface of the Serengeti ecosystem to determine the epidemiology and risk of cross-species transmission between interacting hosts species. DNA was extracted from mycobacterial cultures obtained from sputum samples of 472 tuberculosis (TB) suspected patients and tissue samples from 606 livestock and wild animal species. M. bovis isolates were characterized using spoligotyping and Mycobacterial Interspersed Repetitive Units-Variable Tandem Repeats (MIRU-VNTR) on 24 loci. Only 5 M. bovis were isolated from the cultured samples. Spoligotyping results revealed that three M. bovis isolates from two buffaloes (Syncerus caffer) and 1 African civet (Civettictis civetta) belonged to SB0133 spoligotype. The two novel strains (AR1 and AR2) assigned as spoligotype SB2290 and SB2289, respectively, were identified from indigenous cattle (Bos indicus). No M. bovis was detected from patients with clinical signs consistent with TB. Of the 606 animal tissue specimens and sputa of 472 TB-suspected patients 43 (7.09%) and 12 (2.9%), respectively, yielded non-tuberculous mycobacteria (NTM), of which 20 isolates were M. intracellulare. No M. avium was identified. M. bovis isolates from wildlife had 45.2% and 96.8% spoligotype pattern agreement with AR1 and AR2 strains, respectively. This finding indicates that bTB infections in wild animals and cattle were epidemiologically related. Of the 24 MIRU-VNTR loci, QUB 11b showed the highest discrimination among the M. bovis strains. The novel strains obtained in this study have not been previously reported in the area, but no clear evidence for recent cross-species transmission of M. bovis was found between human, livestock and wild animals.

Abstract
Background
Stomatitis is the most frequent adverse event reported in trials of mTOR-inhibitors, including EVE. In the pivotal phase 3 BOLERO-2 study, stomatitis incidence in the EVE + exemestane (EXE) arm was 59%. The BOLERO-4 study (NCT01698918) evaluated the efficacy and safety of first-line EVE + LET in postmenopausal pts with HR+, HER2− metastatic or locally advanced breast cancer (ABC). BOLERO-4 also assessed the effectiveness of an alcohol-free dexamethasone (0.5 mg/ 5ml; DEX) oral rinse for treating stomatitis in a subset of pts (USA).
Methods
Postmenopausal pts with HR+, HER2− ABC previously untreated for advanced disease received EVE (10 mg/day) + LET (2.5 mg/day).At disease progression, pts were offered EVE (10 mg/day) + EXE (25 mg/day). Pts who had at least one episode of stomatitis received oral stomatitis daily questionnaire (OSDQ), which is a 6 question pt-reported outcome (PRO) survey (Stiff et al, JCO. 2006). A subset of these pts (USA) was randomized (1:1) to receive DEX or standard of care (SOC). The primary objective of investigator-assessed progression-free survival in the first-line setting for ABC was presented previously. A secondary objective was to evaluate the effectiveness of the DEX oral rinse in reducing the severity and duration of stomatitis, using OSDQ data.
Results
Of the total 202 pts enrolled in this study, 52 pts were enrolled in USA, of which, 24 (46.2%) were randomized to receive DEX (n=11) or SOC (n=13), upon confirmation of stomatitis. The median duration of first stomatitis episode was longer per OSDQ (DEX, not estimable vs SOC, 13.7 wk) compared with physician-reported duration (DEX, 1.6 wk vs SOC, 1.9 wk). PRO OSDQ results were similar in both arms.
Among the 202 pts enrolled, 89 (44.1%) filled the OSDQ at their first stomatitis episode. The median time from treatment initiation to first stomatitis episode was 1.7 wk; median duration of stomatitis was 13.7 wk (OSDQ) vs 2.1 wk (physician reported). The majority of pts experiencing stomatitis had moderate/little/no soreness, moderate/low/no pain, and stomatitis had low/no effect on daily activities (Table 1).

Conclusions
Overall, patient-reported median duration of stomatitis was longer than that reported by physicians, most likely due to differences in perceptions and the challenges in collecting and cleaning PRO data. Overall good health score was maintained in the majority of pts experiencing stomatitis and stomatitis had low/no effect on daily activities. However, these results, especially in the randomized subset need to be interpreted with caution owing to the small sample size, missing data and lack of commercially available DEX in most countries.

Abstract
PLAIN ENGLISH SUMMARY Patient and public involvement (PPI) in research is very important, and funders and the NHS all expect this to happen. What this means in practice, and how to make it really successful, is therefore an important research question. This article analyses the experience of a research team using PPI, and makes recommendations on strengthening PPI in research. There were different PPI roles in our study - some people were part of the research team: some were on the advisory group; and there were patient groups who gave specific feedback on how to make research work better for their needs. We used minutes, other written documents, and structured individual and group reflections to learn from our own experiences over time. The main findings were:- for researchers and those in a PPI role to work in partnership, project structures must allow flexibility and responsiveness to different people's ideas and needs; a named link person can ensure support; PPI representatives need to feel fully included in the research; make clear what is expected for all roles; and ensure enough time and funding to allow meaningful involvement. Some roles brought more demands but also more rewards than others - highlighting that it is important that people giving up their time to help with research experience gains from doing so. Those contributing to PPI on a regular basis may want to learn new skills, rather than always doing the same things. Researchers and the public need to find ways to develop roles in PPI over time. We also found that, even for a team with expertise in PPI, there was a need both for understanding of different ways to contribute, and an evolving 'normalisation' of new ways of working together over time, which both enriched the process and the outputs. ABSTRACT Background Patient and public involvement (PPI) is now an expectation of research funders, in the UK, but there is relatively little published literature on what this means in practice - nor is there much evaluative research about implementation and outputs. Policy literature endorses the need to include PPI representation at all stages of planning, performing and research dissemination, and recommends resource allocation to these roles; but details of how to make such inputs effective in practice are less common. While literature on power and participation informs the debate, there are relatively few published case studies of how this can play out through the lived experience of PPI in research; early findings highlight key issues around access to knowledge, resources, and interpersonal respect. This article describes the findings of a case study of PPI within a study about PPI in research. Methods The aim of the study was to look at how the PPI representatives' inputs had developed over time, key challenges and changes, and lessons learned. We used realist evaluation and normalisation process theory to frame and analyse the data, which was drawn from project documentation, minutes of meetings and workshops, field notes and observations made by PPI representatives and researchers; documented feedback after meetings and activities; and the structured feedback from two formal reflective meetings. Results Key findings included the need for named contacts who support, integrate and work with PPI contributors and researchers, to ensure partnership working is encouraged and supported to be as effective as possible. A structure for partnership working enabled this to be enacted systematically across all settings. Some individual tensions were nonetheless identified around different roles, with possible implications for clarifying expectations and deepening understandings of the different types of PPI contribution and of their importance. Even in a team with research expertise in PPI, the data showed that there were different phases and challenges to 'normalising' the PPI input to the project. Mutual commitment and flexibility, embedded through relationships across the team, led to inclusion and collaboration. Conclusion Work on developing relationships and teambuilding are as important for enabling partnership between PPI representatives and researchers as more practical components such as funding and information sharing. Early explicit exploration of the different roles and their contributions may assist effective participation and satisfaction.

Abstract
Total D-amino acids were measured in plasma for 20 non-dialysed patients (creatinine clearance < 12 ml/minute), 20 on CAPD, 20 on haemodialysis and 20 normals. Plasma D-tyrosine and D-phenylalanine were measured in 8 of each group by HPLC. Total D-amino acids, D-tyrosine and D-phenylalanine were significantly greater for patients than normals. D-amino acids and D-tyrosine correlated with creatinine and were decreased during HD. During dialysis, the mean losses for D-tyrosine and D-phenylalanine were similar, about 0.2 mg/CAPD exchange and 3 mg/4 hour haemodialysis (i.e. 2% of the total amino acid, as in plasma). Clearance was unaffected by stereochemical configuration. Urinary losses/24 hour in the non-dialysed patients were 0.35 mg D-tyrosine and 0.25 mg D-phenylalanine. Clearance for D-phenylalanine was greater than for the L-enantiomer. Increases in D-amino acids in renal failure are probably due to depletion of D-amino acid oxidase, but may be enhanced by a D-amino acid rich diet, peptide antibiotics and D-amino acid oxidase inhibiting drugs and metabolites. Possible toxic effects need further investigation.

Abstract
OBJECTIVES To describe the clinical characteristics of epilepsy in a representative sample of the UK population, including seizure frequency and severity; overall severity of epilepsy; patterns of anti-epileptic drug (AED) use; and the impact of epilepsy on patients' lives. Secondly, to determine if these characteristics differ according to age. METHOD A large, geographically comprehensive survey of people with epilepsy by means of a postal questionnaire distributed by general practitioners to 3455 unselected patients receiving AEDs for epilepsy, regardless of age or type of epilepsy and including all regions of the UK. Data were collected on age and gender; age of onset of seizures; seizure frequency and severity; AED use and adverse effect levels; and impact on life of epilepsy. Sub-analyses were performed with stratification by epilepsy severity and age-group. RESULTS There were 1652 completed replies. The mean age was 44.2 years; there were 47.2% males, 48.5% females (4.4% not recorded). The mean age at first seizure, 25.1 years, and the mean duration of epilepsy, 19.7 years, were comparable with previous studies. In the preceding one year, 51.7% of patients had no seizures; 7.9% one seizure, 17.2% 2-9 seizures and 23.2% 10 or more. Sixty-four percent of patients had epilepsy classified as mild and 32% severe. There was a marked and significant decrement of seizure frequency with increasing age. The most commonly used AEDs were carbamazepine (37.4%), valproate (35.7%), phenytoin (29.4%), phenobarbitone or primidone (14.2%) and lamotrigine (10.3%). Monotherapy was used in 68% of patients. Patients taking multiple AEDs reported significantly higher levels of adverse effects and worse seizure control. The major impacts of epilepsy on life were work and school difficulties, driving prohibition, psychological and social life. The impacts listed varied with the epilepsy severity and age. CONCLUSIONS Seizures remain uncontrolled in up to half of all people with epilepsy in the UK with significant impact on work, family and social life. Previously, there has been a deficiency of data on the characteristics of epilepsy in older people, although it is recognized that the condition is of increasing epidemiological importance in this age group. We have found clear differences in the clinical characteristics of epilepsy in older people, particularly that seizure frequency appears to decline with increasing age.

Abstract
BACKGROUND Telephone consultation is the process where calls are received, assessed and managed by giving advice or by referral to a more appropriate service. In recent years there has been a growth in telephone consultation developed, in part, as a response to increased demand for General Practitioner (GP) and Accident and Emergency (A&E) department care. OBJECTIVES To assess the effects of telephone consultation on safety, service usage and patient satisfaction and to compare telephone consultation by different health care professionals. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials, the specialised register of the Cochrane Effective Practice and Organisation of Care (EPOC) group, Pubmed, EMBASE, CINAHL, SIGLE, and the National Research Register. We checked reference lists of identified studies and review articles and contacted experts in the field. The search was not restricted by language or publication status. SELECTION CRITERIA Randomised controlled trials (RCTs), controlled studies, controlled before/after studies (CBAs) and interrupted time series (ITSs) of telephone consultation or triage in a general health care setting. Disease specific phone lines were excluded. DATA COLLECTION AND ANALYSIS Two reviewers independently screened studies for inclusion in the review, extracted data and assessed study quality. Data were collected on adverse events, service usage, cost and patient satisfaction. Due to heterogeneity we did not pool studies in a meta-analysis and instead present a narrative summary of the findings. MAIN RESULTS Nine studies met our inclusion criteria, five RCTs, one CCT and three ITSs. Six studies compared telephone consultation versus normal care; four by a doctor, one by a nurse and one by a clinic clerk. Three studies compared telephone consultation by different types of health care workers; two compared nurses with doctors and one compared health assistants with doctors or nurses. Three of five studies found a decrease in visits to GP's but two found a significant increase in return consultations. In general at least 50% of calls were handled by telephone advice alone. Seven studies looked at accident and emergency department visits, six showed no difference between the groups and one, of nurse telephone consultation, found an increase in visits. Two studies reported deaths and found no difference between nurse telephone triage and normal care. REVIEWERS' CONCLUSIONS Telephone consultation appears to reduce the number of surgery contacts and out-of-hours visits by general practitioners. However, questions remain about its affect on service use and further rigorous evaluation is needed with emphasis on service use, safety, cost and patient satisfaction.

Abstract
OBJECTIVE Following cardiac surgery, patients are transferred from the operating theatre to intensive care. This clinical environment has one nurse per patient and facilities for mechanical ventilation. Patients are kept in this setting until the following day. This practice has been challenged with early extubation of patients. At our institution we have established a fast-track policy including the following features: (1) patient selection; (2) operating list scheduling with fast-track patients first; (3) anaesthetic tailored to early extubation; (4) methodical procedure with warm cardiopulmonary bypass; (5) removal of the arterial line; (6) transfer from intensive care to a separate high dependency unit ('step-down') on the day of operation, where the ratio of nurse to patient is one to three and there are no ventilatory facilities and no invasive monitoring; or (7) to keep these patients on ICU but decrease the nurse to patient ratio. METHOD The case notes of 572 patients who predominantly had myocardial revascularisation, undergoing this process from July 1996 to July 2000 at our institution were reviewed. RESULTS Mean EUROSCORE for the study group was 1.42. The 30-day mortality rate for the study group was 0.34%, mean intensive care time was 5 h 52 min, mean time to extubation was 3 h 10 min, mean readmission rate to intensive care was 0.34% and mean hospital stay from day of operation (inclusive) was 5.65 days. This process increased our throughput by 14.6% (compared to standard practices). COMMENT This study demonstrates that transfer of appropriate patients to a high dependency area from intensive care following cardiac surgery is safe. It allows intensive care beds to be used by more than one patient each day and allows significant cost savings by reducing the nursing ratio per patient.

Abstract
To the best of our knowledge, this prospective study is the first to investigate the prevalence of acetabular labrum tears in athletes presenting with groin pain. Eighteen athletes who presented to our sports clinic with groin pain, underwent clinical assessment and magnetic resonance arthrography (MRa) to detect presence or absence of acetabular labrum tears. Ethical committee approval and informed consent was obtained from each patient. In four out of these eighteen athletes (22%) the MRa demonstrated the presence of acetabular labrum tear. Three of them underwent arthroscopic debridement of their acetabular labrum tears and returned to their sporting activities within 8 months. Clicking sensation of the hip was a sensitive (100%) and specific (85%) clinical symptom to predict labral tears. The internal rotation-flexion-axial compression manoeuvre was sensitive (75%) but not specific (43%). The Thomas test was neither sensitive nor specific. The conclusion of the study is that acetabular labrum tears can be a common cause of groin pain in athletes. Sports clinicians managing athletes with groin pain have to be well aware of the condition.

Abstract
OBJECTIVE To identify factors that patients perceive as influencing control in living with the symptoms of rheumatoid arthritis (RA). METHOD A sample of 40 patients with RA were recruited randomly from an out-patient population. The participants of the sample were interviewed in depth by one researcher to identify perceptions of control. They also completed two self-administered questionnaires, the Health Assessment Questionnaire and the Rheumatology Attitude Index. RESULTS Four major categories were identified that positively influenced perceptions of control in patients living with the consequences of RA. These included: (i) the reduction of physical symptoms; (ii) social support matching perceived need; (iii) the provision of information; and (iv) the medical consultation. Components of the consultation included patient involvement, provision of information, feedback and reassurance, empathy and access to an expert. CONCLUSION The categories identified can be influenced by health-care professionals in the management of the patient, and if the medical consultation is utilized to its full potential it can play a major role in enabling patients with RA to manage the daily symptoms of their condition.

Abstract
Women with epilepsy have different needs from men, particularly associated with childbearing. Despite clinical guidelines, the care of women with epilepsy remains suboptimal. The aim of this study was to establish whether women with epilepsy recall being given information on topics relating to childbearing. Design of study and methods included a postal questionnaire study of 795 women with epilepsy and of childbearing age. The respondents were identified through both general practices and hospital clinics as part of the Clinical Standards Advisory Group study into Epilepsy Services. Of those women who considered the questions personally relevant, 38-48% recalled receiving information about contraception, pre-pregnancy planning, folic acid and teratogenicity, with lower overall proportions among adolescent women. The proportions that recalled receiving information about vitamin K, safety in child-care and breast-feeding were lower at 12, 24 and 24%, respectively. While it is recognised that information provided may not be recalled, our results suggest that further measures are required to improve the effectiveness of information provision in the UK in relation to women of childbearing age with epilepsy.

Abstract
This paper explores the background to epilepsy in terms of medical impact and psychosocial effects. The argument that information and counselling may be central to the person with epilepsy is explored. The evidence from primary research published between 1990 and 2000 investigating the information and counselling needs of people with epilepsy is appraised and synthesized. This paper seeks to answer the following questions: What are the information and counselling needs of people with epilepsy? What are the preferred formats, timing and delivery of information and counselling? What are the outcomes of information giving and counselling for people with epilepsy? The review suggests that there are unmet needs for personal and general information about epilepsy which may include individual or group education and counselling. Information related to gaining control for people with epilepsy and targeted public education may contribute to improved quality of life for people with epilepsy. Information is required which is individually relevant and could be delivered in small groups or as part of an individual counselling service. Specialist epilepsy clinics and specialist nurses can improve patient knowledge and communication and provide an effective and high quality service for people with epilepsy.

Abstract
Nurse educators face the challenge of competing pressures. Programmes must be developed that more adequately prepare students to meet the demands of a changing and complex health care system. These programmes must reflect excellence in teaching and learning and this needs to be achieved within the constraints of economic rationalism. The design of a model based on principles of self directed learning assisted one university to deliver a high quality clinical skills programme.

Abstract
We report two cases, which underwent surgery through Median sternotomy. They were on ACE inhibitors [corrected] pre-operatively. Both of these patients developed persistent dry cough post-operatively, which resulted in sternal wound dehiscence. They had no clinical or bacteriological evidence of sternal wound infection. Although one patient was overweight and had moderately impaired left ventricular function, there were no other associated risk factors. Both patients underwent rewiring of the sternum. Type II receptors inhibitor were introduced post-rewiring, which cured the persistent dry cough. Both the patients are enjoying a good quality of life at 2 year 6 months and 2 years post-rewiring of the sternum.

Abstract
BACKGROUND Valve durability has been a major concern with bioprostheses, and the Tissuemed (Aspire) porcine bioprosthesis was designed to provide a solution to structural valve failure. Because bioprostheses tend to fail by 8 years, the aim of our study was to determine its midterm durability and performance. METHODS We reviewed 506 prostheses that were implanted in 493 patients (287 men; mean age 73 +/- 6 years) between 1991 and 1999. Preoperatively 316 (68%) patients were in New York Heart Association class III or IV. There were 417 (85%) aortic, 61 (12%) mitral, 13 (2.6%) aortic and mitral, and two (0.4%) tricuspid procedures. Concomitant procedures were performed in 163 (33%) patients. Follow-up was complete in 488 (98.9%) patients with a total cumulative follow-up of 1,402 patient-years. RESULTS The 30-day mortality in this elderly population was 10% (95% confidence interval, 8 to 13), with no early valve-related deaths. Patients' survival at 8 years was 46% +/- 7%. This was influenced by the following factors: (1) the patient's age, being worse for those 70 years or older (p = 0.005); (2) those in New York Heart Association functional class III and IV (p = 0.004); (3) those in atrial fibrillation before the operation (p = 0.006); (4) those with poor left ventricular function (p = 0.009); and (5) those who had a previous cardiac operation (p = 0.003). Valve-related complications (expressed as percent per patient-year) were thromboembolism at 0.9%/patient-year; major hemorrhage at 1.4%/patient-year; bacterial endocarditis at 0.4%/patient-year; nonstructural dysfunction at 0.2%/patient-year, and reoperation at 0.2%/patient-year. At 8 years, freedom from thromboembolism was 93% +/- 7%, major hemorrhage, 90% +/- 4%, nonstructural dysfunction, 99% +/- 1%, structural valve failure, 100%, and reoperation, 99% +/- 1%. At follow-up, 98% of survivors were in New York Heart Association class I or II. CONCLUSIONS Our study suggests that at 8 years, the Tissuemed (Aspire) porcine bioprosthesis is durable and has satisfactory performance with low complication rates.

Abstract
Cognitive and adaptive behavioural outcome were studied in the identified survivors of a population based study of non-traumatic coma (NTC) in childhood. Children were assessed early (six weeks) and late (12 months) after NTC. At least 7% of those children in whom no suspicions of prior neurodevelopmental morbidity existed showed moderate or severe disability following NTC. Children over 2 years of age at insult showed some improvement between early and late assessments; however, children below 2 years showed no improvement. Differing age at insult effects were observed between aetiological groups. A relation between early age at first insult and poor outcome was particularly evident among children experiencing NTC caused by epilepsy.

Abstract
The objectives of this study were to provide a comprehensive survey of satisfaction with care, care preferences and information provision for patients with epilepsy, and to formulate recommendations for the development of epilepsy services based on the findings. A questionnaire was distributed to 4620 patients who were currently receiving antiepileptic drugs for epilepsy, regardless of aetiology, duration or severity. Two different samples of patients with epilepsy were questioned: the first an unselected sample drawn from primary care, and the second consisting of consecutive patients drawn from hospital clinics. There were 2394 responses to the questionnaire. Satisfaction with primary and hospital care was high, both overall and for specific aspects. However, two major shortcomings were identified. First, few respondents felt that their care was shared between hospital and GP. Secondly, provision of information about epilepsy was perceived to be poor, particularly by the elderly. Younger patients and patients with severe epilepsy had a higher satisfaction with and preference for hospital care, whereas older age groups were more satisfied with and preferred primary care. Patients' main reasons for preferring primary care were that it was more personal and the GP was more familiar with them, and secondary care was preferred because the hospital doctor knew more about epilepsy. In conclusion, we have conducted the largest representative UK survey of patients' perceptions and views of the care available for epilepsy. Although patient satisfaction was high, information provision is poor and the shared care model is not operating effectively. We recommend that an emphasis be placed on methods for improving the interface between primary and secondary care. The setting up of hospital epilepsy centres, as recommended by the recently published Clinical Standards Advisory Group report on epilepsy, would provide a focus for these efforts and for information provision.

Abstract
The aims of this study were to estimate the proportion of patients with epilepsy who made primary care and/or hospital outpatient medical consultations within 1 year; to formulate a model of the explanatory variables that influence whether patients consult or not; and to estimate the frequency of referral to, and waiting time for, hospital outpatient clinics in patients with new-onset seizures. Suggestions are offered for improvement of epilepsy services based on the findings. A questionnaire was distributed to 3455 unselected patients identified at population level from primary care practices in all NHS regions of the UK. There were 1652 respondents with epilepsy of all types, irrespective of aetiology, duration or severity. Fifty-two per cent of the whole sample made at least one medical consultation of any type specifically for epilepsy (42.0% primary care, 30.5% hospital, 20.4% both). Most patients with controlled epilepsy (74.5%) had no consultations. Of patients with severe epilepsy, 27.5% made no primary care consultations, 43.4% no hospital consultations and 14.1% no consultations of either type. Gender did not influence the likelihood of either GP or hospital consultations in patients with either controlled or active epilepsy. Increasing seizure frequency was associated with a greater likelihood of one or more hospital consultations for epilepsy, whereas increasing duration of epilepsy was associated with a decreased likelihood of either type of consultation. Age affected consultation rates: of those patients over the age of 65 years, only 29.9% made a medical consultation for epilepsy, compared to 53.8% of young adults. Patients under the age of 17 years were less likely to have consulted a GP and more likely to have consulted a hospital doctor. Ninety percent of new-onset patients had been referred to a hospital doctor, and the mean wait was 6.5 weeks. In conclusion, many patients with epilepsy, including severe epilepsy, are not receiving specialist input, and a significant proportion are receiving no medical supervision. The elderly are over-represented in this group. Care tends to be polarized between hospital or primary care, falling short of the ideal of shared care. It will be important to address the influences on consultation seeking in epilepsy, particularly for those patients currently under no medical supervision.

Abstract
The mouse neurotrophin-3 (NT-3) gene has been shown to contain two exons (exon 1A and exon 1B) upstream of the single coding exon (exon 2). These upstream exons are alternatively spliced to the coding exon, generating two different NT-3 transcripts. We investigated whether alternative splicing of two upstream exons also occurs in the human and rat NT-3 gene. It was found that the human and rat NT-3 gene also contains two exons upstream of the main coding exon and that alternative splicing of these upstream exons generates two different NT-3 transcripts : transcript 1A and transcript 1B (TR1B). These two transcripts were widely expressed in several human and rat tissues. Also, a third transcript, transcript 1A1C, derived from splicing of exon 1A to exon 1B before splicing to the coding exon was seen in a small number of rat tissues. Previous quantification of neurotrophin-3 mRNA has not been transcript-specific. Here we describe a transcript-specific semiquantitative RT-PCR method allowing the quantification of TR1B in human tissues. We show that this is the major NT-3 transcript and that expression of this transcript was much higher in the adult when compared with the corresponding fetal tissues.

Abstract
BACKGROUND Protein-energy malnutrition occurs in patients with chronic renal failure primarily due to loss of appetite. The ob gene protein, leptin, which is secreted by adipocytes, regulates body composition by lowering food intake. We have measured plasma leptin in undialysed and dialysed patients and in controls and the concentrations have been related to body composition, dietary intake, and biochemistry. METHODS Plasma leptin was measured by radioimmunoassay in 93 individuals in groups of undialysed, peritoneal dialysed, and haemodialysed patients and controls. Body composition was determined by DEXA. RESULTS Protein-energy malnutrition was evident in non-dialysed and dialysed patients from low lean or fat tissues, plasma albumin and transferrin. A third of the dialysis patients were eating less than prescribed intakes. Leptin relative to total fat mass (ng/ml/kg) was significantly greater for patients than for controls, particularly the dialysed patients. Leptin was highly correlated with total, arm, leg, and all other fat measurements, e.g. r for leptin vsm % total fat was: undialysed 0.88, PD 0.81, HD 0.93, and controls 0.83 (P < 0.0001 for all). Dialysis patients with the highest leptin/fat mass ratio had low protein intakes and significantly lower lean tissue mass. Leptin/fat ratio correlated inversely with dietary intake e.g. with protein intake in g/day and marginally in g/kg of ideal weight/day. Leptin concentration was unrelated to plasma creatinine or residual renal function or to the protein 'nutritional indices', albumin and transferrin. CONCLUSIONS Our data suggests that leptin is markedly increased in some patients with chronic renal failure. The association of increased leptin with low protein intake and loss of lean tissue is consistent with leptin contributing to malnutrition but a definitive role cannot be substantiated by this study.

Abstract
1. We have investigated simultaneous changes in the hydraulic permeability (Lp) and the retention of perfusate macromolecules in single mesenteric venules of anaesthetized rats during perfusion with either histamine or serotonin. 2. The venules were microperfused in situ. Retention of macromolecules was assessed from the effective oncotic pressure (omega delta pi) exerted by the perfusate across the vessel walls. Lp and omega delta pi were estimated by the red cell microperfusion technique. 3. Perfusion with histamine (at concentrations between 16 microM and 3.26 mM) and serotonin (at concentrations between 26 microM and 1.3 mM) transiently increased Lp and reduced omega delta pi. Maximal changes were seen at 6-9 min with histamine and at 3 min with serotonin. 4. Maximal increases in Lp were greater with histamine (approximately 3-fold) than with serotonin (1.5- to 2-fold). Serotonin, however, decreased omega delta pi from a baseline of 14-15 cmH2O to one of 6-7 cmH2O whereas the fall of omega delta pi with histamine was only from 14-15 cmH2O to 10-11 cmH2O. 5. The data are consistent with the hypothesis that serotonin increases permeability by inducing openings in the venular endothelium which do not retain macromolecules. If histamine also increases permeability by gap formation, these gaps are able to retain macromolecules to a significant extent.

Abstract
OBJECTIVE The study examined the impact of easy access to ambulatory services for patients with bipolar disorder in a clinic-based program at a Veterans Affairs medical center. Core program components included medication administration based on treatment algorithms, standardized psychoeducation, and easy access to a single primary nurse provider to enhance continuity of care. The program had no community outreach or extensive rehabilitation components. METHODS The study used a mirror-image design to compare patients' data from the year before program entry when patients received standard clinical care with data for the first year in the program. Process and outcome data from the first 103 patients to complete one year are reported. RESULTS The findings indicated increased patient satisfaction and increased intensity of medication treatment without increased side effects at one year. Although scheduled ambulatory clinic visits increased as expected, use of the emergency room and the psychiatric triage team decreased significantly. Patients who were high utilizers of care before program entry experienced significant reductions in psychiatric hospital days and total mental health expenditures. CONCLUSIONS Easy access to ambulatory care, even if limited to clinic-based services, may have beneficial effects on important process and outcome measures for bipolar disorder. These effects may be attributable to on-demand access to services, continuity of care with a single primary provider, or improved medication delivery to reduce the "efficacy-effectiveness gap" for patients with bipolar disorder. Results indicate that augmenting, rather than limiting, access to ambulatory care for patients with major mental illnesses such as bipolar disorder may reduce overall mental health expenditures.

Abstract
Vascular grafts continue to evolve. Recent developments have been aimed at decreasing porosity, increasing strength of prosthesis, increasing ease of handling and suturing and optimising flow characteristics. This study describes results with a recently developed collagen impregnated polyester prosthesis Hemashield Woven Double Velour, which does not require pre-clotting. Between January 1988 and December, 1991 such prostheses were used in 90 patients at Papworth Hospital. Fifty-eight, were used to replace the ascending aorta, 10 for the arch of the aorta and 28 for the descending aorta seven of whom were for coarctation and four for traumatic transections. In 60 cases the underlying disease was a dissected or ruptured aorta requiring emergency operation. There were 66 survivors with X-ray and CT follow-up of 6-52 months. Median blood loss was 630 ml range 380-1800 ml. There was no leakage from any of the grafts during surgery despite full perioperative heparinisation. For emergency/elective operations (N = 60/30) early mortality was 25%/10% (15/3) and late mortality 5%/6.6% (3/2). Of 15 patients who had interposition grafts for Type A dissection CT scans at 5-47 months showed one with chronic dissection proximal to the repair and 11 with persistent distal dissection. There was no evidence of late bleeding, seroma impaired healing or thickened neointima formation. It is concluded that there are no clinical disadvantages associated with collagen impregnation to set against the notable convenience of initial impermeability.

Abstract
The red cell microperfusion-micro-occlusion technique has been used to measure fluid filtration and reabsorption (Jv/A) at known microvascular pressures (Pc) in single mesenteric venules of anaesthetized rats. The relation between Jv/A and Pc is linear over the range of Pc from 15 to 50 cmH2O and its slope is the hydraulic permeability, Lp. Reproducible estimates of Lp can be made in the same venule in separate microperfusions. The value of Pc at Jv/A = 0 varies linearly with perfusate oncotic pressure and is the effective oncotic pressure of the perfusate, sigma delta pi, when the hydrostatic pressure in the pericapillary fluid is zero. The mean value for Lp (+/- S.E.M.) in forty venules was 2.43 (+/- 0.2) x 10(-7) cm s-1 cmH2O-1. Two potential errors of the micro-occlusion technique (vessel distensibility and marker red cell size) were investigated. It was found that the effects of vessel distensibility had little effect on red cell movements at times later than 2 s after a step change in Pc. Red cell size had a potentially large effect on estimates of the absolute values of Lp. Cooling the mesenteric tissues from 37 to 7 degrees C reduced Lp in proportion to the change in the reciprocal of water viscosity with temperature. Rat venular permeability was shown to be sensitive to histamine, with Lp increasing and sigma delta pi falling in a concentration-dependent fashion with histamine concentrations of 1.6 x 10(-5) to 3.3 x 10(-4) mol l-1 in the perfusate.

Abstract
1. We have investigated the effects of a standardised mixture of hydroxyethylrutosides (HR, Venoruton), a mixture of five of its main components (M) and each of the five components separately (7-mono-HR, 7,4'-di-HR, 7,3',4'-tri-HR, 5,7,3',4'-tetra-HR and 7,3'4'-tri HQ) upon the permeability of single perfused capillaries and venules in the mesenteries of pithed frogs. 2. In each experiment, the hydraulic permeability (Lp) of a single perfused microvessel and the effective osmotic pressure (sigma delta pi) exerted by macromolecules across its walls were estimated by a microcclusion technique, first during control perfusion and then in the presence of a known concentration of test substance. 3. HR, M and 7,4'-di-HR reduced Lp in a similar concentration-dependent manner over the range of 1 microgram ml-1 to 1 mg ml-1 (maximum reduction was to 40% of control Lp at 1 mg ml-1). At perfusate concentrations greater than 1 mg ml-1, these substances reduced Lp to a lesser extent. While the four other test substances reduced Lp significantly when their perfusate concentrations equalled or exceeded 100 micrograms ml-1, they were all less potent than 7,4'-di-HR. 4. The reduction in Lp induced by the mixture of flavonoids was only slightly reversed by subsequent perfusion with flavonoid-free solutions. 5. When permeability was increased by perfusing with protein-free solutions, both HR and 7,4'-di-HR reduced and then reversed the increase in Lp in a concentration-dependent manner over the range of 1 microgram ml-1 to 100 micrograms ml-1. None of the other component flavonoids was effective in restoring Lp under these conditions.

Abstract
Totally implanted central venous access devices provide reliable delivery of repetitive chemotherapy courses. However, placement of these ports requires special expertise and facilities, and is not without risk of major complications. This paper reports the technique of placing a new peripherally accessed, totally implantable, central venous port in 22 patients for the repeated administration of systemic chemotherapy. All ports were successfully placed under local anesthesia, with catheter tip location determined by an electronic sensor wand. The ports have been in use for a total of 387 patient-weeks. One port required removal secondary to an infection at the port site. Twenty-one ports have remained functional for infusion and blood sampling through 99 courses of chemotherapy. Acceptance by patients, nurses, and physicians has been excellent.

Abstract
Sixteen trained nurses from various clinical backgrounds participated in a project designed to describe the process and assess the outcome of their attempts to help a range of patients and clients to stop smoking. A case-study approach was employed and the nurses initiated 68 health education interventions related to smoking cessation. All interventions were tape-recorded and data on patients' and clients' characteristics, smoking history, health beliefs and motivation to give up smoking were also collected. Forty-two patients were followed up 1 year post-intervention. Data collected at this time revealed that 17% had successfully given up smoking, while a further 12% had substantially reduced their cigarette consumption. These findings compare very favourably with those of previous studies in which general practitioners have attempted to help patients stop smoking. The results of the research reported here therefore suggest that nurses have enormous potential for fulfilling a highly effective health education function.

Abstract
During the evaluation of 1% amino acid solution as an alternative osmotic agent to glucose, we measured amino acids and proteins in dialysate, urine and plasma to evaluate the uptake of amino acids and their effects on membrane permeability. Eight patients (plasma albumin less than 35 g/l) were on 21 exchanges of glucose fluid for 4 weeks before and after 12 weeks, during which a solution of 15 amino acids (Baxter '151') was used for the morning exchange. The absorption of amino acids from the single daily '151' exchange increased during the study: 16.4 g at 4 weeks and 17.1 g after 12 weeks (P less than 0.01) with increases in eight amino acids. Amino acid uptake was related to the permeability characteristics of the patients. Following each '151' exchange, 1% of the amino acids absorbed were dialysed into subsequent glucose exchanges. Consequently the net daily gain was 15.0 g increasing to 15.6 g, whereas daily depletion during glucose exchanges was 1.8 g both before and after '151'. Clearance of five proteins increased both at the start and after 12 weeks of '151'. Total protein and prealbumin loss into dialysate increased by about 20%, and when glucose was restored loss of transferrin, albumin and immunoglobulin G decreased. Urinary concentrations were similar throughout. Amino acid uptake from '151' greatly exceeded all losses although our results suggest small reversible increases in macromolecular permeability of the peritoneum.
