Magnesium sulphate in the treatment of acute asthma: evaluation of current practice in adult emergency departments
Background: A recent meta-analysis showed that intravenous and nebulised magnesium sulphate have similar levels of evidence to support their use in the treatment of acute asthma in adults. This consisted of weak evidence of effect on respiratory function and hospital admissions, with wide confidence intervals ranging from no effect to significant positive effects. Current BTS/SIGN guidelines suggest an equivocal role for intravenous magnesium sulphate and no role for nebulised magnesium sulphate. A study was performed to assess what emergency physicians currently do in their management of acute asthma.
Method: A postal survey was undertaken of all adult emergency departments within the UK. A structured question naire was sent to all clinical leads in emergency medicine about their current usage of both intravenous and nebulised magnesium sulphate in the treatment of acute asthma.
Results: 180 of the 251 emergency departments in the UK responded (72%). Magnesium sulphate was used in 93%, mostly because it was expected to relieve breathlessness (70%) or reduce HDU/ITU admissions (51%). It was predominantly given to those patients with acute severe asthma (84%) and life-threatening exacerbations (87%), with most stating they would give the drug if there was no response to repeated nebulisers (68%). In comparison, nebulised magnesium sulphate was only used in two emergency departments (1%). The main reason for not administering the drug via a nebuliser was insufficient evidence (51%).
Conclusions: Intravenous magnesium sulphate is widely used for acute asthma, usually for patients with severe or life-threatening asthma who have not responded to initial treatment. Nebulised magnesium sulphate, by contrast, is hardly used at all. The use of intravenous magnesium sulphate is more extensive than current guidelines or available evidence would appear to support
A randomised controlled trial to measure the effect of chest pain unit care upon anxiety, depression, and health-related quality of life [ISRCTN85078221]
Background
The chest pain unit (CPU) has been developed to provide a rapid and accurate diagnostic assessment for patients attending hospital with acute, undifferentiated chest pain. We aimed to measure the effect of CPU assessment upon psychological symptoms and health-related quality of life.
Methods
We undertook a single-centre, cluster-randomised controlled trial. Days (N = 442) were randomised in equal numbers to CPU or routine care. Patients with acute chest pain, undiagnosed by clinical assessment, ECG and chest radiograph, were recruited and followed up with self-completed questionnaires (SF-36 and HADS) at two days and one month after hospital attendance.
Results
Patients receiving CPU assessment had significantly higher scores on the physical functioning (difference 5.1 points; 95% CI 1.1 to 9.0), vitality (4.6; 1.3 to 8.0), and general health (5.7; 2.3 to 9.2) dimensions of the SF-36 at two days, and significantly higher scores on all except the emotional role dimension at one month. They also had significantly lower depression scores on the HADS depression scale at two days (0.93; 0.34 to 1.51) and one month (1.0; 0.36 to 1.66). However, initially lower anxiety scores at two days (0.89; 0.21 to 1.56) were not maintained at one month (0.48; -0.26 to 1.23). CPU assessment was associated with reduced prevalence (OR 0.71; 95% CI 0.52 to 0.97) and severity (6.5 mm on 100 m visual analogue scale; 95% CI 2.2 to 10.8) of chest pain at one month, but no significant difference in the proportion of patients taking time off work (OR 0.82; 95% CI 0.54 to 1.04).
Conclusion
CPU assessment is associated with improvements in nearly all dimensions of quality of life and with reduced symptoms of depression
Disease and psychological status in ankylosing spondylitis.
Objectives. Psychological factors may be important in the assessment and management of ankylosing spondylitis (AS). Our primary objective was to describe associations between disease and psychological status in AS, using AS-specific assessment tools and questionnaires. Our secondary objectives were to identify patient subgroups based on such associations and to determine the stability of the measures over time.
Methods. A total of 110 patients were assessed at 6-monthly intervals up to four times using tools to measure disease [Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI) and the Bath Ankylosing Spondylitis Metrology Index (BASMI)], psychological [Hospital Anxiety and Depression Questionnaire (HADS), Health Locus of Control—Form C Questionnaire (HLC-C)] and generic health [Short form (SF)-36] status.
Results. Eighty-nine participants completed all four assessments. Throughout the study, BASDAI, BASFI and BASMI scores correlated significantly with anxiety, depression, internality and health status, but not with levels of belief in chance or powerful others. Clinically anxious or depressed subgroups had significantly worse BASDAI and BASFI, but not BASMI, scores. BASMI scores were the least closely linked to psychological status. Mean scores for disease, psychological and health status were clinically stable over the 18 months period.
Conclusions. Disease status scores in AS correlated significantly with anxiety, depression, internality and health status. Interpretation of AS disease scores should take an account of psychological status and the choice of measures used. These findings have important potential applications in AS management and monitoring, including the identification of patients for biological therapies
Information sheets for patients with acute chest pain: randomised controlled trial
Objectives: To determine whether providing an information sheet to patients with acute chest pain reduces anxiety, improves health related quality of life, improves satisfaction with care, or alters subsequent symptoms or actions.
Design: Single centre, non-blinded, randomised controlled trial.
Setting: Chest pain unit of an emergency department.
Participants: 700 consecutive patients with acute chest pain and no clear diagnosis at initial presentation.
Interventions: After a diagnostic assessment patients were randomised to receive either standard verbal advice or verbal advice followed by an information sheet.
Main outcome measures: The primary outcome was anxiety (hospital anxiety and depression scale). Secondary outcomes were depression (hospital anxiety and depression scale), health related quality of life (SF-36), patient satisfaction, presentation with further chest pain within one month, lifestyle change (smoking cessation, diet, exercise), further information sought from other sources, and planned healthcare seeeking behaviour in response to further pain. Results 494 of 700 (70.6%) patients responded. Compared with those receiving standard verbal advice those receiving advice and an information sheet had lower mean hospital anxiety and depression scale scores for anxiety (7.61v8.63, difference 1.02, 95% confidence interval 0.20 to 1.84) and depression (4.14 v 5.28, difference 1.14, 0.41 to 1.86) and higher scores for mental health and perception of general health on the SF-36. The information sheet had no significant effect on satisfaction with care, subsequent symptoms, lifestyle change, information seeking, or planned actions in the event of further pain.
Conclusions: Provision of an information sheet to patients with acute chest pain can reduce anxiety and depression and improve mental health and perception of general health but does not alter satisfaction with care or other outcomes.

Which diagnostic tests are most useful in a chest pain unit protocol?
Background
The chest pain unit (CPU) provides rapid diagnostic assessment for patients with acute, undifferentiated chest pain, using a combination of electrocardiographic (ECG) recording, biochemical markers and provocative cardiac testing. We aimed to identify which elements of a CPU protocol were most diagnostically and prognostically useful.
Methods
The Northern General Hospital CPU uses 2–6 hours of serial ECG / ST segment monitoring, CK-MB(mass) on arrival and at least two hours later, troponin T at least six hours after worst pain and exercise treadmill testing. Data were prospectively collected over an eighteen-month period from patients managed on the CPU. Patients discharged after CPU assessment were invited to attend a follow-up appointment 72 hours later for ECG and troponin T measurement. Hospital records of all patients were reviewed to identify adverse cardiac events over the subsequent six months. Diagnostic accuracy of each test was estimated by calculating sensitivity and specificity for: 1) acute coronary syndrome (ACS) with clinical myocardial infarction and 2) ACS with myocyte necrosis. Prognostic value was estimated by calculating the relative risk of an adverse cardiac event following a positive result.
Results
Of the 706 patients, 30 (4.2%) were diagnosed as ACS with myocardial infarction, 30 (4.2%) as ACS with myocyte necrosis, and 32 (4.5%) suffered an adverse cardiac event. Sensitivities for ACS with myocardial infarction and myocyte necrosis respectively were: serial ECG / ST segment monitoring 33% and 23%; CK-MB(mass) 96% and 63%; troponin T (using 0.03 ng/ml threshold) 96% and 90%. The only test that added useful prognostic information was exercise treadmill testing (relative risk 6 for cardiac death, non-fatal myocardial infarction or arrhythmia over six months).
Conclusion
Serial ECG / ST monitoring, as used in our protocol, adds little diagnostic or prognostic value in patients with a normal or non-diagnostic initial ECG. CK-MB(mass) can rule out ACS with clinical myocardial infarction but not myocyte necrosis(defined as a troponin elevation without myocardial infarction). Using a low threshold for positivity for troponin T improves sensitivity of this test for myocardial infarction and myocardial necrosis. Exercise treadmill testing predicts subsequent adverse cardiac events
Do You Think You\u27re What They Say You Are? Reflections on Jesus Christ Superstar
Jesus Christ Superstar (dir. Norman Jewison, 1973) is a hybrid which, though influenced by Jesus films, also transcends them. Its rock opera format and its focus on Holy Week make it congenial to the adaptation of the Gospels and its characterization of a plausible, non-stereotypical Jesus capable of change sets it apart from the traditional films and aligns it with The Last Temptation of Christ and Jesus of Montreal. It uses its depiction of Jesus as a means not of reverence but of interrogation, asking him questions by placing him in a context full of overtones of the culture of the early 1970s, English-speaking West, attempting to understand him by converting him into a pop-idol, with adoring groupies among whom Jesus struggles, out of context, in an alien culture that ultimately crushes him, crucifies him and leaves him behind
Operating lease finance in the UK retail sector
The paper documents the importance of leasing in the UK retail sector and estimates the potential balance sheet impact of new accounting proposals to bring all leases onto lessees’ balance sheets. Off-balance sheet operating leases are shown to be a major source of finance, and far more important (3.3 times higher) than on-balance sheet long-term debt; by contrast, finance leases are immaterial. Operating leased assets, the major part of which is ‘land and buildings’ (98%), represent a significant proportion (28%) of reported total assets. Capitalization of operating leases would have a major impact on nine key performance ratios and would alter the ranking of companies markedly. The findings suggest that operating leases need careful consideration in estimating retailers’ financial risk, in comparing cross-national performance and in research studies of capital structure decisions
Assessing the potential impact of lease accounting reform: A review of the empirical evidence
Accounting standard-setters have proposed that the right to use assets (including land and buildings) acquired under operating lease contracts should be recognized on the balance sheet of lessee companies. In recent years, several empirical research studies have investigated the potential impact of the proposed changes in accounting for leases. The current paper reviews this work and presents some new evidence, for a property audience. It summarizes evidence that operating leases represent a major source of finance for many companies generally, and more specifically for companies in the retail sector. Recognition of operating leases on the lessee's balance sheet would have a significant impact on performance measures, especially gearing. If markets are informationally 'efficient' such changes should have little impact. However, research evidence on efficiency with respect to lease accounting information is mixed. What's more, company managers do not believe that the market is efficient so are likely to behave as if the markets are 'inefficient'. Possible reactions include reduced use of leasing, shorter lease contract terms, more break clauses, or increased use of contingent rental agreements. It seems likely that lessors will be under pressure to bear greater risks.This paper was presented at the RICS Cutting Edge 2001 Conference, Oxford
