Abstract: A detailed study of several Micromegas detectors prototyped for the COMPASS and CLAS12 experiments is presented. Using a 150GeV/c pion beam, the discharge probability was measured for several detector variants including bulk and non-bulk Micromegas. A detector equipped with an additional GEM foil as pre-amplification stage was also tested. A resistive coating of the readout strips was found to reduce the amplitude of the discharge by at least two orders of magnitude which was below the detection limit of the experimental setup. The effects of the micro-mesh type and material were investigated as well as the influence of the drift gap. Response in the presence of a 1.5T transverse magnetic field was also studied. The measurements presented were performed during a RD51 beam test period. [Copyright &y& Elsevier]

Abstract: We present first discharge rate measurements for Micromegas detectors in the presence of a high longitudinal magnetic field in the GeV kinematical region. Measurements were performed by using two Micromegas detectors and a photon beam impinging a CH2 target in the Hall B of the Jefferson Laboratory. One detector was equipped with an additional GEM foil, and a reduction of the discharge probability by two orders of magnitude compared to the stand-alone Micromegas was observed. The detectors were placed in the FROST solenoid providing a longitudinal magnetic field up to 5T. It allowed for precise measurements of the discharge probability dependence with a diffusion-reducing magnetic field. Between 0 and 5T, the discharge probability increased by a factor of 10 for polar angles between 19° and 34°. A GEANT4-based simulation developed for sparking rate calculation was calibrated against these data in order to predict the sparking rate in a high longitudinal magnetic field environment. This simulation is then used to investigate the possible use of Micromegas in the Forward Vertex Tracker (FVT) of the future CLAS12 spectrometer. In the case of the FVT a sparking rate of 1Hz per detector was obtained at the anticipated CLAS12 luminosity. [Copyright &y& Elsevier]

Abstract: Aim: To describe (a) changes in the organisation of training in cardiopulmonary resuscitation (CPR) and the treatment of cardiac arrest in hospital in Sweden and (b) the clinical achievement, i.e. survival and cerebral function, among survivors after in-hospital cardiac arrest (IHCA) in Sweden. Methods: Aspects of CPR training among health care providers (HCPs) and treatment of IHCA in Sweden were evaluated in 3 national surveys (1999, 2003 and 2008). Patients with IHCA are recorded in a National Register covering two thirds of Swedish hospitals. Results: The proportion of hospitals with a CPR coordinator increased from 45% in 1999 to 93% in 2008. The majority of co-ordinators are nurses. The proportions of hospitals with local guidelines for acceptable delays from cardiac arrest to the start of CPR and defibrillation increased from 48% in 1999 to 88% in 2008. The proportion of hospitals using local defibrillation outside intensive care units prior to arrival of rescue team increased from 55% in 1999 to 86% in 2008. During the past 4 years in Sweden, survival to hospital discharge has been 29%. Among survivors, 93% have a cerebral performance category (CPC) score of I or II, indicating acceptable cerebral function. Conclusion: During the last 10 years, there was a marked improvement in CPR training and treatment of IHCA in Sweden. During the past 4 years, survival after IHCA is high and the majority of survivors have acceptable cerebral function. [Copyright &y& Elsevier]

Abstract: The aim of this pilot study was to evaluate the clinical utility of quantitative CD64 measurements to differentiate between systemic inflammation in response to surgical trauma and postoperative bacterial infection. In a consecutive series of 153 patients undergoing elective vascular surgery, peripheral venous blood samples were taken preoperatively on admission and postoperatively during the first 24h. The samples were analysed for C-reactive protein (CRP), total leucocyte counts (white blood cell (WBC)), serum procalcitonin (PCT) and neutrophil CD64 expression. Of the 153 patients, the focus is on those with (1) postoperative infection alone (group 1; n =1 4); (2) pre- and postoperative infection (group 2; n =6); and (3) postoperative fever with no other signs of infection (group 3; n =29). In group 1, all four markers were significantly increased in the 24h after surgery: CD64 (p =0.001), CRP (p =0.001), WBC (p =0.002) and PCT (p =0.012); in group 2, there was no significant difference in the CD64 (p =0.116), WBC (p =0.249) and PCT (p =0.138) values, whereas a marginal significance was shown for CRP (p =0.046); and the results for group 3 were similar to those of group 1. This pilot study suggests that the role of neutrophil CD64 measurements in facilitating the diagnosis of early postoperative infection merits further investigation. [Copyright &y& Elsevier]

CARDIOPULMONARY resuscitation , *RESUSCITATION , *ELECTRIC countershock , *NURSES - Abstract
Summary: Introduction: Construction of an effective in-hospital resuscitation programme is challenging. To document and analyse resuscitation skills assessment must provide reliable data. Benchmarking with a hospital having documented excellent results of in-hospital resuscitation is beneficial. The purpose of this study was to assess the resuscitation skills to facilitate construction of an educational programme. Materials and methods: Nurses working in a university hospital Jorvi, Espoo (n =110), Finland and Sahlgrenska University Hospital, Göteborg (n =40), Sweden were compared. The nurses were trained in the same way in both hospitals except for the defining and teaching of leadership applied in Sahlgrenska. Jorvi nurses are not trained to be, nor do they act as, leaders in a resuscitation situation. Their cardiopulmonary resuscitation (CPR) skills using an automated external defibrillator (AED) were assessed using Objective Structured Clinical Examination (OSCE) which was build up as a case of cardiac arrest with ventricular fibrillation (VF) as the initial rhythm. The subjects were tested in pairs, each pair alone. Group-working skills were registered. Results: All Sahlgrenska nurses, but only 49% of Jorvi nurses, were able to defibrillate. Seventy percent of the nurses working in the Sahlgrenska hospital (mean score 35/49) and 27% of the nurses in Jorvi (mean score 26/49) would have passed the OSCE test. Statistically significant differences were found in activating the alarm (P <0.001), activating the AED without delay (P <0.01), setting the lower defibrillation electrode correctly (P <0.001) and using the correct resuscitation technique (P <0.05). The group-working skills of Sahlgrenska nurses were also significantly better than those of Jorvi nurses. Conclusions: Assessment of CPR-D skills gave valuable information for further education in both hospitals. Defining and teaching leadership seems to improve resuscitation performance.

Objectives: To investigate the impact of patient characteristics and treatment modality (graft thrombectomy vs thrombolysis) on the results of redo procedures for occluded above-knee prosthetic femoropopliteal grafts implanted for critical ischaemia. Material and methods: Fifty-five procedures (thrombolysis 24 and thrombectomy 31) were performed on 24 prostheses (23 patients, 24 limbs) between January 1990 and December 2001. All cases were prospectively registered. Graft patency, limb salvage and survival rates were studied and subgroups of patients were compared. Risk factors were analysed with the use of log rank test and Cox proportional hazard analysis. Results: Half of the 24 initial procedures to restored patency failed within one month. The outcome of second- or third-time redo procedures was similiar. The primary patency rates of all 55 redo procedures were 32% at three months, 28% at six months and 12% at 12 months. The results of thrombectomy and thrombolysis were similar. Re-opened grafts additionally treated for an underlying anastomotic stenosis had significantly better patency as compared with re-opened grafts without a pre-existing stenosis on both univariate analysis (p =0.024) and multivariate analysis (p =0.027, hazard ratio 2.813). The one-year limb salvage rate was 76%. The one- and five-year survival rates were 87% and 52%, respectively. Conclusions: The results of redo procedures for occluded above-knee prosthetic grafts were disappointing. Grafts in which a graft-related stenosis was treated performed better than grafts in which occlusion could not be attributed to an underlying stenosis. Such cases should most likely be offered conservative treatment, amputation or a new arterial reconstruction. [Copyright &y& Elsevier]

Abstract: Objectives: To investigate the impact of clinical risk factors, plasma homocysteine and haemostatic variables on the results after endovascular treatment of symptomatic atherosclerosis of the common iliac artery. Design: Prospective observational study. Setting: University hospital. Patients and method: The study included 139 technically successful interventions in 103 patients. Technical success was defined as ≤30% residual stenosis as seen on the post treatment angiogram. Blood samples for analyses of fasting plasma values of homocysteine, fibrinogen, D-dimer, activated protein C resistance were drawn upon admission. Median follow-up for all procedures was 22 months (range 0–55 months). Patency was defined as freedom from ≥50% restenosis or reocclusion. Results: The technical success rate for all procedures was 93%. The 1-year cumulative primary patency rate based on intention to treat was 85%. Multivariate analysis revealed a significant independent association between patency rates and levels of fibrinogen and homocysteine and the nature of the lesion treated (stenosis vs. occlusion). Conclusion: The aetiology of restenoses and reocclusions is probably multifactorial. Procoagulant activity, the nature of the lesion treated and homocysteine levels within and above the upper range of normal limits are important risk factors for failure after endovascular treatment of the common iliac arteries.

Abstract: Objectives: To study early mortality and long-term survival of patients more than 80 years of age having elective open repair for abdominal aortic aneurysm (AAA). Design: Retrospective multicenter cohort study. Material: One hundred and five patients, 23 women and 82 men, with a median age of 82 years, operated at three Norwegian hospitals during the period 1983–2002. Method: Survival analyses were based on data from medical records and the Norwegian Registrar''s Office of Births and Deaths. Expected survival was based on mortality rates of the general population, matched by age, sex, and calendar period. Relative survival was calculated as the ratio between the observed and the expected survival. Results: During the study period there has been a 10 fold increase in octogenarians treated with open operation for AAA. Early mortality (30-day) for the whole group of patients was 10.5% (95% confidence interval (95% CI) 5.3–18.0), and similar for both genders. The 5-year survival rate was 47% (95% CI 35.9–57.4), and not significantly different from that of a matched group in the general population. Patients aged 84 years or more had a median survival time of 35 months (95% CI 18.5–51.6). Conclusion: The number of AAA operations in octogenarians has increased considerably during 20 years. Octogenarians operated electively for AAA has higher 30-day mortality as compared to younger patients. Their long-term survival appears similar to a matched control group. The benefit of surgery must be carefully considered against the perioperative risk, especially for the oldest octogenarians. [Copyright &y& Elsevier]

Abstract: An innovative technique for the readout of a detector is presented, based on the assumption that at least two neighbouring elements (e.g. strips) record a signal from the passage of a particle. This concept, called genetic multiplexing, is particularly adapted to Micro-Pattern Gaseous Detectors, but can also be used for other types of detectors. Furthermore, the degree of multiplexing can be easily adapted in the detector design to the incident flux of particles. The technique has been tested on a large, 50×50cm2 Micromegas prototype equipped with 1024 strips and read with only 61 channels. First results obtained with cosmics are reported, showing the good performance of the detector. Genetic multiplexing offers the possibility to build large area detectors with a considerably reduced number of electronic channels, and has therefore a wide range of applications in and beyond particle physics.

Abstract: The recent developments on resistive Micromegas have enhanced the performance of this detector, and in particular have offered the possibility to reach higher amplification gains in stable operation. In this paper, the detection capabilities of a resistive Micromegas in air have been investigated. A clear Fe55 spectrum has been obtained, as well as MIP signals using cosmic rays. In the latter case, the detection efficiency reaches 42%, and could probably be further improved. The stable operation of a gaseous detector in air, i.e. without bottles, pipes or safety systems, can lead to many new applications or simplifications of existing setups. [Copyright &y& Elsevier]

Method: All patients suffering an in-hospital cardiac arrest in whom cardiopulmonary resuscitation (CPR) was attempted at Sahlgrenska University Hospital in Göteborg between 1994 and 2006 and at nine further hospitals in Sweden between 2005 and 2006. Results: In all, 1810 patients were included in the survey, 395 (22%) of whom had a previous history of diabetes. Patients with a history of diabetes differed from those without such a history by having a higher prevalence of previous myocardial infarction, stroke, heart failure and renal disease. They were more frequently treated with anti-arrhythmic drugs during resuscitation. Whereas immediate survival did not differ between groups (51.7% and 53.1%, respectively), patients with diabetes were discharged alive from hospital (29.3%) less frequently compared with those without diabetes (37.6%). When correcting for dissimilarities at baseline, the adjusted odds ratio for being discharged alive (diabetes/no diabetes) was 0.57 (95% CL 0.40–0.79). Conclusion: Among patients suffering an in-hospital cardiac arrest in Sweden in whom CPR was attempted, 22% had a history of diabetes. These patients had a lower survival rate, which cannot simply be explained by different co-morbidity. [Copyright &y& Elsevier]

Summary: Background: Survival after in-hospital cardiac arrest (IHCA) differs considerably between hospitals. This study tries to determine whether this difference is due to patient selection because of the hospital level of care or to effective resuscitation management. Methods: Prospectively collected data on management of in-hospital cardiac arrests from Sahlgrenska Hospital, a tertiary hospital in Gothenburg, Sweden (cohort one) and from five Finnish secondary hospitals (cohort two). A multiple logistic regression model was created for predicting survival to hospital discharge. Results: A total of 954 cases from Sahlgrenska Hospital and 624 patients from the hospitals in Finland were included. The delay to defibrillation was longer at Sahlgrenska than at the five Finnish secondary hospitals (p =0.045). Significant predictors of survival were: (1) age below median (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.5–2.8); (2) no diabetes (OR 1.9, CI 1.2–2.9); (3) arrests occurring during office hours (OR 1.5, CI 1.1–2.2); (4) witnessed cardiac arrest (OR 6.3, CI 2.6–15.3); (5) ventricular fibrillation or ventricular tachycardia as the initial rhythm (OR 4.9, CI 3.5–6.7); (6) location of the arrest (compared to arrests in general wards, GW): thoracic surgery and heart transplantation ward (OR 2.9, CI 1.5–5.9), interventional radiology (OR 4.8, CI 1.9–12.0) and other in-hospital locations (3.0, CI 1.6–5.7) and (7) hospital (compared to arrests at Sahlgrenska Hospital); arrests at Etelä-Karjala Central Hospital [CH] (OR 0.3, CI 0.1–0.7), Päijät-Hame CH (OR 0.3, CI 0.1–0.8) and Seinäjoki CH (OR 0.4, CI 0.3–0.7). Conclusion: The comparison of survival following IHCA between different hospitals is difficult, there seems to be undefined factors greatly associated with outcome. A great variability in survival within different hospital areas probably because of differences in patient selection, patient surveillance and resuscitation management was also noted. A locally implemented strong in-hospital chain of survival is probably the only way to improve outcome following IHCA. [Copyright &y& Elsevier]

Abstract: The Prototype AT-TPC, a detector based on time projection chamber (TPC) technology was built at the National Superconducting Cyclotron Laboratory, Michigan State University. The chamber gas, called the active target, of the Prototype AT-TPC is utilized simultaneously as a reaction target and a tracking medium of charged particles for measuring low-energy nuclear reactions. In pursuit of luminosity, efficiency and resolution for reaction studies at a new generation of radioactive isotope facilities, the Prototype AT-TPC provides one of the largest active volumes in the world measuring 25cm in diameter and 50cm long along the beam axis, millimeter-precision tracking capability, and a high electric field of 1kV/cm/atm for fast electron drift, which limits the detector dead time. Commissioning of the detector using standard alpha sources and radioactive 6He beams has demonstrated the detector''s long-term stability as well as its performance, which allowed good reconstruction of reaction kinematics.

Objectives: To investigate the results of endovascular treatment of symptomatic, atherosclerotic lesions of the infrarenal aorta.Patients and Method: This is a retrospective study including 30 procedures performed on 25 patients in the period from 1990 through 2003. There were 16 women (64%) and 9 men, with a mean age of 55 years (range 35-81 years). The indication was disabling intermittent claudication in all cases. Preoperative assessment was done with ankle-arm pressure measurement and angiography. The mean length of the lesions was 2.5cm (range 1-6cm). One lesion was a short occlusion and nine were >90% stenoses. The remaining 20 lesions were significant (>70%) stenoses. The procedure was done with PTA alone in 13 cases, and with additional stenting in 17.Results: The procedures were technically successful in 28 cases and clinically successful in all 30. In two cases, a >50% residual stenosis was not dilated further because of stretch pain. The mean observation time was 40 months (range 0-135 months). The primary 2 and 5 year patency rates calculated on basis of intention to treat were 90 and 77%. The primary assisted patency rate was 90% at 2 years and 83% at 5 years. Eight patients developed significant restenosis, of which five were treated with a new endovascular procedure. Two failures were treated conservatively and one with surgical thrombendarterectomy.Conclusion: Endovascular treatment of isolated atherosclerotic lesions of the infrarenal aorta is feasible in patients with suitable anatomy. Clinical success rates are high and long-term patency is good. Complications are few and minor. The majority of failures are amenable to new endovascular treatment. [ABSTRACT FROM AUTHOR]- Published
