Abstract
Introduction Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopment disorder characteristically compromising of three persistent symptoms; Inattention, hyperactivity and impulsivity. Within the Tameside and Glossop CCG continuous performance tests from the company QbTech are used to aid diagnosis. Objectives
The aim of this research is to evaluate the effectiveness of using both the QbCheck (triage tool) and QbTest (diagnostic tool) concordantly in the diagnostic pathway of ADHD in young people. Methods 20 Patients who had undergone both performance tests were identified and then five components evaluated in the QbCheck were then compared to the QbTest results. Results
In the five areas identified by both the QbTest and QbCheck up to 80% had the same outcomes in the two tests. However, in one area (hyperactivity) only 60% of QbChecks outcomes were replicated by the QbTest. The symptom of inattention most commonly correlated between the two tests. The average wait between tests was 9.8 months. 100% of those who scored on QB Check, received diagnosis of ADHD, suggesting high referrer specificity. Conclusions QbCheck diagnostic outcomes are comparable to patients who have undergone both the QbCheck and QbTest, only having one of these continuous performance tests making up the ADHD diagnostic pathway could be cost and time saving in the pathway to diagnosis. As QbCheck can be completed within the child’s school this reduces the number of clinic appointments that need to be attended by patients and their families.

Abstract
BACKGROUND/AIMS Gastric antral vascular ectasia (GAVE) is a rare acquired vascular lesion of the gastric antrum. The most frequent presentation of GAVE is iron deficiency anemia. Endoscopic therapy is the mainstay of treatment. However, there is no consensus regarding the optimal treatment modality. METHODS A retrospective cohort study was performed on patients with GAVE, including patients receiving endoscopic therapy. Treatment was with either argon plasma coagulation (APC) or endoscopic band ligation (EBL). Basic demographic data, indication for index procedure, number of sessions, and pre- and post-hemoglobin levels were collected. The aim of the study was to compare outcomes across the two treatment modalities. RESULTS One hundred and seventeen diagnoses of GAVE were made. Sixty-two patients (53%) required endoscopic treatment for symptomatic GAVE (female, n=38, 61%; mean age of 74.4 years). Two hundred and eighteen procedures were performed during the study period. APC was performed (n=161, 74%) more frequently than EBL (n=57, 26%). Patients treated with APC at index required a median 5 subsequent therapeutic interventions (APC or EBL), while those treated with EBL at index required a further 2.9 treatments (EBL only) (p<0.05). CONCLUSION APC was the most common treatment modality employed. We demonstrate an increasing incidence of EBL. Patients treated with EBL at index treatment required fewer subsequent treatment sessions and had a greater mean rise in hemoglobin. This suggests a more effective endoscopic response with EBL.

Abstract
Abstract
Background/Introduction
Transthyretin amyloidosis (TTR) is a cause of restrictive cardiomyopathy and heart failure predominantly in elderly men. Two main factors have moved TTR amyloidosis from super-specialist centres into mainstream cardiology:
We aimed to determine the potential magnitude of referrals to our embryonic cardiac TTR service from patients having routine bone scans for non-cardiac reasons. We planned to estimate the prevalence of cardiac TTR in our local over 65 male population to plan service provision.
Methods
All HDP bone scans performed at a teaching and research hospital in the UK from the 2017/18 financial year were reviewed (n=1530). Our hospital is the only provider of these scans locally. Of these, 1399 were for oncological and musculoskeletal (oncology/MSK) indications and 37 were referred to specifically “exclude amyloidosis”. We excluded paediatric and duplicate follow-up imaging. There are approximately 140,000 people over aged 65 living within our catchment region. We have assumed approximately 50% are male.
Results
Myocardial uptake was present in 7/1399 of the oncology/MSK group and 3/7 (43%) of these already had features of heart failure. In these 7 patients bone scans were performed to investigate bony metastases in 6 (1 oesophageal cancer and 5 for prostate cancer) and 1 following an orthopaedic procedure. Cardiac uptake was present in 10/37 of the “exclude amyloid” group. In those with cardiac uptake across both groups (17) 94% were male with a mean age of 83 (sd ±6.59) and 41% were from the oncology/musculoskeletal group. Incidental cardiac uptake was seen in 1:200 routine HDP scans. When looking at males >65 specifically the uptake rate increases to (6 out of 701 scans) i.e. 1:117. Assuming there is no increased risk of TTR in patients with prostate or oesophageal cancer, then an estimate of cardiac TTR in the 75,000 males over the age of 65 locally would be approximately 640 men.
Conclusions
Bone scans account for 41% of all HDP scans with incidental cardiac uptake and therefore represents a significant potential referral source for a cardiac amyloid service. Our data suggests a potential prevalence of cardiac amyloidosis in 1:117 men over 65 with 43% already having heart failure symptoms and signs. Our age and sex specific prevalence suggests cardiac TTR is neither a rare nor unusual diagnosis. We will use our prevalence estimate to ensure our cardiac TTR service is resourced appropriately. We suggest that cardiac amyloid and cardio-oncology services should include pathways incorporating rapid access routes for suitable patients with incidental cardiac uptake on bone scans performed by non-cardiologists.

Abstract
OBJECTIVE Eye tracking in three dimensions is novel, but established descriptors derived from two-dimensional (2D) studies are not transferable. We aimed to develop metrics suitable for statistical comparison of eye-tracking data obtained from readers of three-dimensional (3D) "virtual" medical imaging, using CT colonography (CTC) as a typical example. METHODS Ten experienced radiologists were eye tracked while observing eight 3D endoluminal CTC videos. Subsequently, we developed metrics that described their visual search patterns based on concepts derived from 2D gaze studies. Statistical methods were developed to allow analysis of the metrics. RESULTS Eye tracking was possible for all readers. Visual dwell on the moving region of interest (ROI) was defined as pursuit of the moving object across multiple frames. Using this concept of pursuit, five categories of metrics were defined that allowed characterization of reader gaze behaviour. These were time to first pursuit, identification and assessment time, pursuit duration, ROI size and pursuit frequency. Additional subcategories allowed us to further characterize visual search between readers in the test population. CONCLUSION We propose metrics for the characterization of visual search of 3D moving medical images. These metrics can be used to compare readers' visual search patterns and provide a reproducible framework for the analysis of gaze tracking in the 3D environment. ADVANCES IN KNOWLEDGE This article describes a novel set of metrics that can be used to describe gaze behaviour when eye tracking readers during interpretation of 3D medical images. These metrics build on those established for 2D eye tracking and are applicable to increasingly common 3D medical image displays.

Abstract
BACKGROUND Medical education faces challenges posed by widening access to training, a demand for globally competent healthcare workers and progress towards harmonisation of standards. AIM To explore potential challenges arising from variation in diversity and educational background of medical school entrants. METHOD This study investigated the reported experience and confidence, in a range of 31 generic skills underpinning learning, of 2606 medical undergraduates entering 14 medical schools in England and South Africa, using a validated questionnaire. RESULTS Responses suggest that there is considerable similarity in prior educational experience and confidence skills profiles on entry to South African and English medical schools. South African entrants reported significantly more experience in 'Technical skills', 'Managing their own Learning', and 'Presentation', while English students reported increased experience in 'IT' skills. South African undergraduates reported more confidence in 'Information Handling', while English students were more confident in 'IT' skills. The most noticeable difference, in 'IT' skills, is probably due to documented differences in access to computer facilities at high school level. Differences between individual schools within each country are noticeable. CONCLUSIONS Educators need to acquire a good understanding of their incoming cohorts, and ensure necessary tailored support for skills development.

Abstract
ROCView has been developed as an image display and response capture (IDRC) solution to image display and consistent recording of reader responses in relation to the free-response receiver operating characteristic paradigm. A web-based solution to IDRC for observer response studies allows observations to be completed from any location, assuming that display performance and viewing conditions are consistent with the study being completed. The simplistic functionality of the software allows observations to be completed without supervision. ROCView can display images from multiple modalities, in a randomised order if required. Following registration, observers are prompted to begin their image evaluation. All data are recorded via mouse clicks, one to localise (mark) and one to score confidence (rate) using either an ordinal or continuous rating scale. Up to nine "mark-rating" pairs can be made per image. Unmarked images are given a default score of zero. Upon completion of the study, both true-positive and false-positive reports can be downloaded and adapted for analysis. ROCView has the potential to be a useful tool in the assessment of modality performance difference for a range of imaging methods.

Abstract
BACKGROUND An important issue in the transplantation of livers procured from cardiac death donors (CDDs) concerns why some centres report equivalent outcomes and others report inferior outcomes in transplantations using CDD organs compared with standard criteria donor (SCD) organs. Resolving this discrepancy may increase the number of usable organs. OBJECTIVES This study aimed to test whether differences in cold ischaemic time (CIT) are critical during CDD organ transplantation and whether such differences might explain the disparate outcomes. METHODS Results of CDD liver transplants in our own centre were compared retrospectively with results in a matched cohort of SCD liver recipients. Endpoints of primary non-function (PNF) and ischaemic cholangiopathy (IC) were used because these outcomes are clearly associated with CDD organ use. RESULTS In 22 CDD organ transplants, CIT was a strong predictor of PNF or IC (P = 0.021). Minimising CIT in CDD organ transplants produced outcomes similar to those in a matched SCD organ transplant cohort at our centre and in SCD organ transplant results nationally (1- and 3-year graft and patient survival rates: 90.9% and 73.3% vs. 77.6% and 69.2% in CDD and SCD grafts, respectively. A review of the published literature demonstrated that centres with higher CITs tend to have higher rates of PNF or IC (correlation coefficient: 0.41). CONCLUSIONS These findings suggest that a targeted effort to minimise CIT might improve outcomes and allow the safer use of CDD organs.

Abstract
The diagnosis of cirrhosis requires screening for oesophageal varices by upper gastrointestinal endoscopy. In many countries, serological tests and elastography are replacing liver biopsy for diagnosing cirrhosis. The aims of this study were to see whether there was an optimal cut-off of liver stiffness that could predict the presence of large (>F2) oesophageal varices and whether this was disease specific. A total of two hundred and twenty-two patients with all cause cirrhosis (Child class A) were screened, and 211 had successful elastography and are included in the analysis. Of the patients studied, one hundred and thirty-two patients had no or small F1 varices and 79 had large varices. Liver stiffness of 19.8 kPa had a negative predictive value of 91% and a positive predictive value of 55% with an area under the curve (AUC) on receiver operating characteristics (ROC) of 0.73 in differentiating between small and large varices. Seven patients with large varices would have been incorrectly classified. In the 157 patients with hepatitis C as the aetiology of cirrhosis, the negative predictive value was 98% and only one patient was misclassified. Liver stiffness was superior in diagnostic accuracy to platelet count in all patients. A liver stiffness of >19.8 kPa could be utilized as a cut-off for endoscopy and beta blocker utilization, particularly in patients with hepatitis C.

Abstract
BACKGROUND AND PURPOSE Highly active antiretroviral therapy (HAART) has improved morbidity and mortality and quality of life, revitalized communities and transformed the perception of HIV/AIDS from being a "death sentence" to a chronic illness. Strict and sustained adherence to medication is essential long-term viral suppression. In April 2005, an Adherence Support Programme was introduced to Jamaica's HIV Programme, whereby Persons Living with HIV/AIDS (PLWHA) who had achieved high levels of adherence were trained to provide support to other PLWHA in order to increase their adherence to HAART regimens. METHODS A cross-sectional survey of 116 individuals with advanced HIV and on HAART was performed in June and July 2006. RESULTS Many participants were unemployed, poor persons with limited education. Based on self-report of seven-day adherence, 54.8% of persons were 95-100% adherent, 37.5% were 80-94% adherent and 7.7% were < 80% adherent. Having interacted with an adherence counsellor was not associated with adherence levels. Factors associated with nonadherence were: being away from home (38%), sleeping through dose-time (37%), forgetfulness (37%) and running out of pills (31%). Having no food (26.9%), not wanting to be seen taking medication (200%) and intolerable side effects (18.8%) were also reasons given. Only 44% of persons used aids to remind them of dose times. CONCLUSION Adherence in this study group is low and may have worsened since 2005. More emphasis must be placed on preparing adults to start HAART The use of pillboxes and other reminders such as alarm clocks and cell phones must be reinforced.

Abstract
BACKGROUND Discharge from the hospital is a critical transition point in a patient's care. Incomplete handoffs at discharge can lead to adverse events for patients and result in avoidable rehospitalization. Care transitions are especially important for elderly patients and other high-risk patients who have multiple comorbidities. Standardizing the elements of the discharge process may help to address the gaps in quality and safety that occur when patients transition from the hospital to an outpatient setting. METHODS The Society of Hospital Medicine's Hospital Quality and Patient Safety committee assembled a panel of care transition researchers, process improvement experts, and hospitalists to review the literature and develop a checklist of processes and elements required for ideal discharge of adult patients. The discharge checklist was presented at the Society of Hospital Medicine's Annual Meeting in April 2005, where it was reviewed and revised by more than 120 practicing hospitalists and hospital-based nurses, case managers, and pharmacists. The final checklist was endorsed by the Society of Hospital Medicine. RESULTS The finalized checklist is a comprehensive list of the processes and elements considered necessary for optimal patient handoff at hospital discharge. This checklist focused on medication safety, patient education, and follow-up plans. CONCLUSIONS The development of content and process standards for discharge is the first step in improving the handoff of care from the inpatient to the posthospital setting. Refining this checklist for patients with specific diagnoses, in specific age categories, and with specific discharge destinations may further improve information transfer and ultimately affect patient outcomes.

Abstract
The work was carried out to investigate differences in visual search characteristics between groups of observers with different levels of experience in the task of pulmonary nodule detection in chest radiology and we report here on these differences in respect of time related decisions. Volunteer observers were divided into three groups depending on their level of expertise. There were eight radiologists, eight radiographers and eight novices. Their task was to detect pulmonary nodules in a test bank of 120 digitized posteroanterior (PA) chest radiographs. Five of the eight radiographers were tested twice: once before and once after a 6-month training programme in interpretation of the adult chest radiograph. During each test session the observers' eye movements were tracked. Data on the observers' decisions through Alternate Free Response Operating Characteristic (AFROC) methodology were correlated to their eye-movement and fixation patterns. True negative decisions from all observers were associated with shorter fixation times than false negative decisions. No correct negative decisions were made after fixations exceeding 3 s.

OBJECTIVE To determine whether social deprivation is associated with neonatal unit admission. SETTING English district general hospital. METHOD Retrospective review of neonatal unit admission records between 1990 and 2002. RESULTS There was a linear increase in admission rates with increasing deprivation. The admission rate was 6.1% of live births for infants in the most affluent quartile compared with 11.1% for those in the most deprived quartile. Admission rates for all indications except jaundice and feeding problems increased with increasing deprivation. CONCLUSION Social deprivation correlates strongly with neonatal morbidity and the need for neonatal unit admission. This finding has implications for professionals in public health and primary and secondary care.

Abstract
The provision of a formal consultation service for inpatients between subspecialists is little studied. We prospectively surveyed the pattern of inpatient consultations from hospital-based generalists and surgeons to the gastroenterology (GI) service for inpatients in a large urban teaching hospital over a 5 month period. There are two GI consultants/attendings and five GI registrars/fellows on the service. A formal consultation is made by the requesting team to the GI service using the hospital computer network. All referrals over a 5 month period were prospectively analysed. 242 consecutive inpatient referrals were sent to the GI service over 5 months. Average age was 56 years, 48.8% males. 32 consultants/attendings from other disciplines sent referrals. Most patients were seen within one working day. Urgent referrals were seen without delay. The commonest reasons for referral were abdominal pain (15.8%), percutaneous endoscopic gastrostomy (PEG) tube insertion (13.6%), diarrhoea (12.8%), abnormal liver blood tests (10%), nausea and vomiting (8.2%), anaemia (6.2%), and melaena (4.9%). Iatrogenic diseases accounted for 6.2% of consultations. Ongoing patient care was assumed by the GI team in 9.5% of referrals. 15.3% required a second consultation visit before discharge. 22.7% of referrals were followed in the GI outpatients' clinic after discharge. 51.2% underwent an endoscopic procedure. 13.6% of referrals were for PEG tube insertion. A quarter of these were considered unsuitable for immediate PEG tube insertion. Subspecialty consultation provides an expert opinion, encourages discussion and learning, and improves patient care. In our experience, the provision of specialist advice and reassurance often speeded up a patient's work-up and expedited discharge. However, evaluating referral patients and subsequently providing ongoing inpatient and outpatient care and provision of endoscopy for these referrals contributes significantly to the workload of the GI service.

Abstract
OBJECTIVE To examine social trends in the number of singleton births and birth weight in an English health district between 1990 and 2001, using an area based deprivation index. DESIGN Analysis of routinely collected hospital data. SETTING Wirral Health District in north west England. PARTICIPANTS All 48 452 live births to Wirral residents from 1990 to 2001. MAIN OUTCOME MEASURES Birth numbers, birth weight, and standard deviation score for birth weights for singleton births. Townsend material deprivation scores derived from postcodes. RESULTS The number of singleton births fell by 28% over the 12 years. The fall in the least deprived Townsend quartile (45%) was more than triple that in the most deprived quartile (gamma = 0.045; 95% confidence interval (CI) = 0.036 to 0.054; p < 0.001). Over the study period, the mean birth weight in the least deprived Townsend quartile was 141 g higher than in the most deprived quartile. There was a highly significant association between the standard deviation score for birth weight and Townsend quartile (tau-b = -0.062; 95% CI = -0.068 to -0.055; p < 0.001). Numbers of low birth weight babies in the least deprived quartile fell disproportionately compared with those from the most deprived quartile (gamma = 0.17; 95% CI = 0.09 to 0.25; p < 0.001). CONCLUSION The reduction in birth rate in the Wirral was significantly less in the most deprived districts. This was accompanied by related differences in mean birth weight and the number of low birth weight babies, indicating increasing social inequality in birth trends. Previously described social inequity in birth weight and the number of low birth weight babies continues in the north west of England.

Abstract
AIM To examine the sleeping arrangements of sudden infant death syndrome (SIDS) cases on the Wirral. In particular to determine the prevalence of bed sharing with mothers who smoke, a known risk factor for SIDS. METHODS Retrospective study of postmortem determined cases of SIDS from 1995 to 2000 on the Wirral peninsula (population 350 000, 3500 annual births). Ambulance crew reports, case notes, health visitor reports, postmortem reports, and case discussion records were studied for each case. RESULTS There were 25 cases of SIDS in the postneonatal age group over the six year period. In nine cases the baby was bed sharing with the mother, of whom seven were smokers. Five of these mothers reported using alcohol or illicit drugs on the night of their infant's death. In two further cases the baby slept on a sofa with a parent. CONCLUSIONS Bed sharing and smoking remain important risk factors for SIDS. Mothers should be advised ante- and postnatally of this combination of risk factors. Such advice should also include a recommendation not to sleep with their baby if under the influence of alcohol or illicit drugs, and never to sleep on a sofa with their baby. All "Child Health Record" books given to parents on the Wirral now include this advice. "Reduce the Risk" advice leaflets given to parents pre- and postnatally also now carry the recommendation, and health visitors and midwives have been educated with respect to these additions.

Abstract
Major depression is associated with both hypothalamic-pituitary-adrenal (HPA) axis overactivity and immune system activation. Depression is a common occurrence following interferon (IFN)-a treatment. While IFN-alpha is known to stimulate the HPA axis, little is known about the effects of exogenous IFN-a in humans on the proinflammatory cytokine interleukin (IL)-6, a marker of immune system activation. This study examined the acute effects of IFN-alpha on cortisol and IL-6 release, and the time course of any changes in these variables. Serum cortisol and plasma IL-6 were assessed in healthy volunteers over an 8-h period following 3 million units subcutaneous IFN-alpha or placebo using a double-blind, placebo-controlled crossover design. IFN-alpha resulted in a significant increase in both cortisol and IL-6. Regular sampling over 8 h did not delineate any sequential effect of the rise in these variables over time. We conclude that IFN-alpha acutely stimulates both the HPA axis and proinflammatory cytokine release. The hypothesis that the effect of IFN-alpha on the HPA axis is indirect and mediated by IL-6 was not supported by this study. Our findings are nonetheless of relevance to the aetiology of depression following IFN-alpha.

Abstract
Vitamin D deficiency has been described in the Asian migrants to the UK from the early 1960s. In spite of some suggestions that this problem is declining, we continue to see clinical cases of vitamin D deficiency with osteomalacia presenting to hospital. As the aetiology of this condition is associated with social, cultural and dietary factors, we screened associated family members of 18 index cases (three males 15 females, age range 12-73 years) who presented with clinical vitamin D deficiency to hospital. Of the 36 (21 females, 15 males) screened, 67% of these had evidence of vitamin D deficiency as judged by a 25(OH)VitD of < 5 microg L-1 (5-40). Some subjects also had hypocalcaemia (n=2), low PO4 (n=7), raised PTH (n=8) and raised alkaline phosphatase (n=11), indicating severe symptomatic, but unrecognized, vitamin D deficiency. Family screening seems an effective way of identifying Asian subjects with vitamin D deficiency who otherwise remain undiagnosed. A preventative policy with implementation is long overdue for this easily treatable condition.

Abstract
The causes of ulcerative colitis and Crohn's disease are unknown. Current research is focused on genetic factors but environmental factors may also be important. Exposure to infections in early life is believed to reduce the incidence of bronchial asthma. We hypothesised that exposure to enteric bacteria and infections in early life may also reduce the incidence of idiopathic inflammatory bowel disease. Chronic inflammatory bowel disease may be a by-product of our over-clean environment. Social groups with poorer living standards might be expected to have a lower prevalence of this condition. The "traveller" or itinerant community in Ireland is one such group. We therefore attempted to estimate the prevalence of inflammatory bowel disease in the traveller population. Twenty five of 30 gastroenterologists or surgeons in Ireland responded to requests for information. None could recall ever seeing a "traveller" with idiopathic inflammatory bowel disease. While genetic factors cannot be excluded, a low prevalence of idiopathic inflammatory bowel disease would support the environmental hypothesis.

Abstract
Each of the following papers gives an account of a different UK clinical ethics committee. The committees vary in the length of time they have been established, and also in the main focus of their work. The accounts discuss the development of the committees and some of the ethical problems that have been brought to them. The issues raised will be relevant for other National Health Service (NHS) trusts in the UK that wish to set up such a committee.

Abstract
Heterotrimeric G proteins mediate the earliest step in cell responses to external events by linking cell surface receptors to intracellular signaling pathways. G(z) is a member of the G(i) family of G proteins that is prominently expressed in platelets and brain. Here, we show that deletion of the alpha subunit of G(z) in mice: (i) impairs platelet aggregation by preventing the inhibition of cAMP formation normally seen at physiologic concentrations of epinephrine, and (ii) causes the mice to be more resistant to fatal thromboembolism. Loss of G(zalpha) also results in greatly exaggerated responses to cocaine, reduces the analgesic effects of morphine, and abolishes the effects of widely used antidepressant drugs that act as catecholamine reuptake inhibitors. These changes occur despite the presence of other G(ialpha) family members in the same cells and are not accompanied by detectable compensatory changes in the level of expression of other G protein subunits. Therefore, these results provide insights into receptor selectivity among G proteins and a model for understanding platelet function and the effects of psychoactive drugs.

Abstract
AIM To compare patient triggered, with conventional fast rate, ventilation in a randomised controlled trial using the incidence of chronic lung disease as the primary outcome measure. METHODS Three hundred and eighty six preterm infants with birthweights from 1000 to 2000 g, and requiring ventilation for respiratory distress syndrome within 24 hours of birth, were randomised to receive either conventional or trigger ventilation with the SLE 2000 ventilator. RESULTS There were no significant differences in the incidence of chronic lung disease (28 day and 36 week definitions), death, pneumothorax, intraventricular haemorrhage, number of ventilator days, or length of oxygen dependency between groups. CONCLUSIONS Patient triggered ventilation in preterm infants with respiratory distress syndrome is feasible. No significant differences, when compared with conventional fast rate ventilation in important medium and longer term outcome measures, were evident.

Abstract
A low-cost store-and-forward teledermatology system using digital images for the remote diagnosis and management of skin tumours was evaluated. Two hospitals participated in the trial. Patients were seen face to face at one hospital, and had their images and clinical history viewed remotely by a different dermatologist at a second hospital. A preliminary receiver operating characteristics (ROC) analysis revealed clinical agreement between the teledermatologist and face-to-face dermatologist in 93% of cases in terms of their assessment of the benign/malignant nature of the lesions. Sensitivity of the judgements was 88% and specificity was 80%. These preliminary findings indicate the potential for remote management of skin tumours using a low-cost system in the National Health Service.

In extending the results of previous research in a manner consistent with the concept of relative deviance, significant differences in these variables are found across the three groups. Implications of the findings for theory, service delivery, and policy are also considered.

Abstract
Near patient testing for glucose is now a widely accepted procedure in hospital wards and clinics. However, in a neonatal ward where the detection of hypoglycaemia rather than hyperglycaemia is of paramount importance, it is more difficult to find a suitable glucose monitoring instrument. We compared two Hemocue blood glucose analysers (Hemocue Ltd) in our special care baby unit (SCBU) with the laboratory procedures and found that the Hemocue may overestimate the glucose by as much as 2.5 mmol/L. In addition, Hemocue analysers are costly to run. We feel these analysers may be more useful in a general ward rather than in a SCBU.

Abstract
The Problem Oriented Screening Instrument for Teenagers (POSIT) serves as a key aspect of the preliminary screening activities at the Hillsborough County Juvenile Assessment Center. We report on a reliability study of POSIT, involving an examination of the relationships between the youths' initial and second admission POSIT results for different time intervals between administration of the instrument. The results indicate the POSIT provides consistent indication of potentially troubled youths who are in need of in-depth assessment and intervention or treatment services.

Abstract
We report the results of a study of the predictors of recidivism to a Juvenile Assessment Center in Hillsborough County, Florida, involving over 2,000 youths processed at the center during its first 8 months of operation. Consistent with previous research, younger aged youths, youths with abuse or neglect histories, with previous arrests for property, violence, or drug offenses, with potential vocational, leisure-recreation, and family problems, or who were arrested on property felony charges were likely to recidivate. The program activity and policy implications of these results are discussed.

Abstract
Mastoparan, a tetradecapeptide found in wasp venom that stimulates G-proteins, increases insulin secretion from beta-cells. In this study, we have examined the role of heterotrimeric G-proteins in mastoparan-induced insulin secretion from the insulin-secreting beta-cell line beta-TC3. Mastoparan stimulated insulin secretion in a dose-dependent manner from digitonin-permeabilized beta-TC3 cells. Active mastoparan analogues mastoparan 7, mastoparan 8, and mastoparan X also stimulated secretion. Mastoparan 17, an inactive analogue of mastoparan, did not increase insulin secretion from permeabilized beta-TC3 cells. Mastoparan-induced insulin secretion from permeabilized beta-TC3 cells was inhibited by pretreatment of the cells with pertussis toxin, suggesting that mastoparan-induced insulin secretion is mediated through a pertussis toxin-sensitive G-protein present distally in exocytosis. Enriched insulin secretory granules (ISG) were prepared by sucrose/nycodenz ultracentrifugation. Western immunoblotting performed on beta-TC3 homogenate and ISG demonstrated that G alpha i was dramatically enriched in ISG. Levels of G alpha o and G alpha q were comparable in homogenate and ISG. Mastoparan stimulated ISG GTPase activity in a pertussis toxin-sensitive manner. Mastoparan 7 and mastoparan 8 also stimulated GTPase activity in the ISG, while the inactive analogue mastoparan 17 had no effect. Selective localization of G alpha i to ISG was confirmed with electron microscopic immunocytochemistry in beta-TC3 cells and beta-cells from rat pancreas. In contrast to G alpha o and G alpha q, G alpha was clearly localized to the ISG. Together, these data suggest that mastoparan may act through the heterotrimeric G-protein G alpha i located in the ISG of beta-cells to stimulate insulin secretion.

Abstract
The Alzheimer amyloid precursor protein (APP) undergoes complex processing resulting in the production of a 4-kDa amyloid peptide (A beta) which has been implicated in the pathogenesis of Alzheimer's disease. Recent studies have shown that cells can secrete carboxyl terminus truncated APP derivatives (APP-S) in response to physiological stimulus. We have used human central nervous system neurons (NT2N) derived from a teratocarcinoma cell line (NT2) to study the signal transduction pathways involved in APP-S secretion and A beta production. Muscarinic receptors (m2 and m3) as well as the heterotrimeric GTP-binding protein Gq and the beta 1 isoform of phospholipase C were present in NT2N neurons. Stimulation of the muscarinic receptor with carbachol resulted in phospholipase C activation as shown by a transient increase in the second messengers 1,2-diacyl-sn-glycerol and inositol 1,4,5-trisphosphate. Carbachol also caused an increase in intracellular Ca2+ levels measured in single NT2N neurons. Under these conditions, carbachol caused a time-dependent 2-fold increase in APP-S secretion into the medium. In contrast, prolonged treatment with carbachol caused a decrease in A beta production into the medium. These results suggest that APP-S secretion and A beta production in NT2N neurons are regulated by the muscarinic/phospholipase C signal transduction pathway. Furthermore, activation of this pathway results in dissociation of APP-S secretion and A beta production.

Abstract
Osteocalcin or bone Gla protein (BGP) is secreted by osteoblasts, and its serum concentration is elevated in a number of conditions with high bone turnover. A comparison of serum osteocalcin with total (TALP) and bone specific alkaline phosphatase (BALP) and urinary hydroxyproline/creatinine (OHP/Cr ratio) was performed in 13 patients with active Paget's disease of bone. BGP did not correlate significantly with either BALP or TALP, but did show a significant correlation with OHP/Cr ratio (r = 0.76; P < 0.01). BGP does not appear to be as sensitive a marker as BALP or TALP in Paget's disease.

Abstract
How can the new deal for juniors be implemented in today's overstretched health service? How do you get clinicians and management to work together? On the Wirral falling house officer morale and recruitment stimulated a new approach, action learning, which proved to be highly successful. Action learning is not a new approach in management terms, but it is rarely used in the health service. Guided by an experienced facilitator, a group of people learn management skills by exploring and resolving practical problems relevant to them. A group of general practitioners and consultants used action learning to teach themselves more about management and at the same time to make changes which addressed many of the junior doctors' difficulties and solved the hospital recruiting problem.

Abstract
Hemolysates from the adult bullfrog, Rana catesbeiana, show an unusually high degree of cooperativity of oxygen binding with Hill coefficients greater than 4. The principal components of the tetrameric hemoglobin, B and C, do not show this high cooperativity when isolated, but it reappears when the components are mixed. Sedimentation velocity measurements show that the unusual behavior results from the mixed association of components B and C to form complexes larger than tetramers. Computer simulation of the sedimentation behavior of mixtures of deoxygenated B and C components shows that the gradient profiles can be satisfactorily described in terms of an equilibrium between the B and C tetramers and a BC2 trimer. The simplest model consistent with the results is the mixed association: B + C<-->BC and BC + C<-->BC2, with the second binding constant being higher than the first, indicating significant cooperativity. The extent of association is highest at low pH and low temperature. The dissociation of the B.C complex with low oxygen affinity to higher affinity B and C molecules during oxygenation results in greatly increased cooperativity of oxygen binding with higher Hill coefficients than possessed by either component alone in equilibria measured between 5 and 25 degrees C and between pH 6 and 8.
