    1991-06-01

    The authors have used an immunoradiometric assay (IRMA) to measure intact parathormone (PTH). The serum-levels of PTH followed a log-normal distribution in a population of 85 healthy post-meno-pausal women, with a geometric mean of 1.9 pmol/l and a range of 0.8 to 6.1 pmol/l. The correlation between measurements performed using the IRMA and a radioimmunoassay which measured the C-terminal portion of the PTH molecule was 0.85. It was only the IRMA, however, that could measure subnormal values. Two of 27 patients with primary hyperparathyroidism had PTH-values in the upper reference interval. The rest of the patients had elevated levels. Patient with hypercalcemia due to malignancy had subnormal or low normal PTH values. Half of the patients with hypoparathyroidism had PTH below the limit of detection. 16 refs., 6 figs., 3 tabs.

    Full Text Available Norges Idrettsforbund og Olympiske og Paralympiske Komité (NIF har en uttalt målsetting om en åpen og inkluderende idrett. Hvordan kommer dette til uttrykk i den praktiske virksomheten? Denne artikkelen, som bygger på data fra en undersøkelse om likestilling og mangfold i den organiserte idretten (NIF, retter søkelyset mot arbeid med inklusjon av ungdom med minoritetsbakgrunn på ulike organisasjonsnivå i NIF: særforbund, idrettskretser og idrettslag. Datamaterialet er kvalitative intervju med representanter fra ulike organisasjonsnivå. Resultatene viser at NIFs overordnede politikk i varierende grad nedfelles i særforbundenes virksomhet, i idrettskretsene og i idrettslagene. Av særforbundene skiller Fotballforbundet og Klatreforbundet seg ut som aktive pådrivere i arbeidet med inkludering. Mange idrettslag oppfattet slike spørsmål som lite aktuelle i sitt rekrutteringsområde. Representanter for lag som hadde erfaring med inkludering og rekruttering av minoritetsungdom, tilkjennega varierte erfaringer og synspunkter.

  13. Konsum av risiko-matvarer - Beskrivelse av en undersøkelse som skal kartlegge konsum av matvarer med betydning for inntaket av miljøgifter

    Directory of Open Access Journals (Sweden)

    Helle Margrete Meltzer

    2009-11-01

    Full Text Available  SAMMENDRAGI perioden 1999-2001 vil det bli gjennomført tre kostholdsundersøkelser som til sammen skal kartlegge konsum avmatvarer med betydning for inntaket av miljøgifter i Norge, fortrinnsvis kadmium, kvikksølv, PCB og dioksiner.Disse giftene finnes hovedsakelig i krabbe, flatfisk, skjell, gjedde og abbor, lever eller nyre fra vilt og viltvoksendesopp. Fordi gjennomsnittskonsumet er lavt, spørres det ikke spesifikt om disse matvarene i landsdekkende kostholdsundersøkelsersom 'Norkost'. Hensikten med studien er å kunne gi en bedre beskrivelse av eksponeringsfordelingeni befolkningen med tanke på miljøgifter. Fordelingen er antakelig skjev, dvs. et stort antall personerventes å ha et lavt inntak og noen få personer ventes å ha et relativt høyt inntak av de undersøkte stoffene. Eventuelleukjente risikogrupper vil kunne avdekkes, og det er av stor interesse å undersøke hvor stor eksponeringen i deutsatte gruppene er.Del A av undersøkelsen er landsdekkende og omfatter en postal frekvensundersøkelse til 10 000 tilfeldig valgtepersoner mellom 18 og 79 år. Del B omfatter en postal frekvensundersøkelse til 6000 tilfeldig valgte personer i sekskommuner, der tre er kystkommuner og tre er innlandskommuner. Kommunene blir valgt ut fra kjennskap til godtilgang på de aktuelle matvarene. Vi antar at der tilgangen på matvarene er god, er konsumet høyere. Del C avundersøkelsen vil omfatte høykonsumenter av aktuelle matvarer, valgt fra del B av undersøkelsen. Dette vil være endybdestudie der analyser av miljøgifter i blod, hår og urin også skal inngå.Undersøkelsen er den første i sitt slag her til lands og vi kjenner ikke til at tilsvarende studier er gjort i andreland. Hensikten med artikkelen er å gi en beskrivelse av undersøkelsen i en tidlig fase av gjennomføringen.Meltzer HM, Bergsten C, Stene LC, Stigum H, Wiborg ML, Lund-Larsen K, Alexander J. Consumption ofcontaminated foods – Description of a dietary survey

    1997-11-01

    The authors have compared clinical, immunological and radiological data in 20 patients with myasthenia gravis and thymoma and in 21 patients with myasthenia gravis and thymic atrophy. The median age at onset was 54 years in the thymoma group and 63 years in the thymic atrophy group. The severity of the disease was similar in the two groups, and there was no significant difference in the concentration of acetylcholine receptor antibodies. CA antibodies were demonstrated in 17/20 thymoma patients and in 6/21 with thymic atrophy, while 19/20 thymoma patients had antibodies to titin, compared with 9/21 among those with thymic atrophy. The diagnosis and treatment of patients with myasthenia gravis is based upon an evaluation of clinical, immunological and radiological data. 28 refs., 2 tabs.

    Full Text Available This article is based upon a study of the experiences of physiotherapists working with elderly depressed patients and the use of physical activity. Depression in the elderly is a common condition, and it is estimated to be the second most common cause of failing health towards 2020. Physical activity has a positive effect on depression in the elderly. The aim of this study was to investigate the experiences of physiotherapist`s in the treatment of elderly depressed patients over 65 years of age. Data was collected by qualitative reasearch interviews of 5 physiotherapists. Important findings of this study were that the physiotherapists experienced that they did not get any referrals to treatment solely due to depression, and that they needed a different approach to physical activity compared to other patient groups.

    Schmelter, Christopher; Raab, Udo; Lazarus, Friedrich; Ruppert, Volker; Vorwerk, Dierk

    2015-08-01

    The study was designed to assess outcomes of arteriovenous (AV) accesses after interventional stent-graft deployment in haemodialysis patients. 63 haemodialysis patients with 66 AV fistulas and AV grafts were treated by interventional stent-graft deployment from 2006 to 2012 at our hospital. Data of these patients were retrospectively analysed for location of deployed stent-grafts, occurrence and location of (re-)stenosis and (re-)thrombosis. Complex stenosis was the most frequent indication for stent-graft deployment (45.5%), followed by complications of angioplasty with vessel rupture or dissection (31.8%). A high rate of procedural success was achieved (98.5%). The most frequent location of the deployed stent-graft was the draining vein (66.7%). Stent-graft deployment was more frequent in AV grafts than in AV fistulas. Primary patency was 45.5% at 6 month, 31.3% at 12 month and 19.2% at 24 month. Primary patency was significantly better for AV fistulas than for AV grafts with deployed stent-grafts. Patency of the deployed stent-graft was much better than overall AV access primary patency with deployed stent-graft. Re-stenosis with thrombosis was the most frequent indication for re-intervention. Most frequent location of re-stenosis was the draining vein (37.1%), followed by stenosis at the AV access (29.5%) and the deployed stent-graft (23.5%). Re-stenosis and re-thrombosis remain frequent in AV fistulas and AV grafts in haemodialysis patients despite stent-graft deployment. Re-stenosis of the deployed stent-graft is, only in the minority of the cases, responsible for AV access dysfunction.

    Full Text Available Next-of-kins’ experiences when using volunteers for palliative patients living at home The aim of this study was to illuminate next-of-kins’ experiences when using volunteers supplementing community health care services for palliative patients living at home. The study has a qualitative approach. Nine individual interviews were conducted with next of kin from a municipality in Southern Norway. Use of volunteers for palliative care in the home was a relief for next-of-kin, especially prominent for families who had limited social network. Planned volunteering resulted in the best results. Use of volunteer was also found helpful for families as they were given a "breathing space" and a certain normalization of everyday life. The volunteers followed up activities related to the patient that the next-of-kin to a limited extent managed to attend. This affected the next-of-kin’s conscience in a positive way. The next-of-kin experienced the volunteers to be empathetic, they could inspire confidence and showed good characteristics to assist ill people and their next-of-kin. The next-of-kin needed regular relief from volunteers as a supplement to the community health care services. The volunteers were well suited to meet people, who were in a difficult situation, and with their approach they had strong confidence in the next-of-kin and gave them relief in a challenging environment. The coordinator for palliative care was a key person in relation to the link between families, patients in palliative care and the volunteers.

    Full Text Available Patient Safety has a high priority on the national and international health care agenda. The incidence of adverse events is estimated to be too high and for a variety of reasons, a fair amount of such events are not reported. Hence, the aim of this study was to explore how midwives and mental health nurses experience and deal with adverse events. The study had a qualitative approach. Semi-structured interviews were conducted with 25 midwives and mental health nurses. The data analysis strategy was systematic text condensation. Two primary themes emerged from the interviews: a Nurses have a moral obligation to report, and b Adverse events puts the individual in a difficult situation. The findings suggest developing a clearer understanding of the relationship between individual and organizational factors. In addition, management is proposed as the key factor in establishing good practice for reporting. More research is required in order to understand the psychosocial aspects of reporting adverse events, and the dynamics involved in professional decision-making in patient safety activities.

En slik oversikt er ikke tidligere sammenfattet, selv om det er over 40 år siden ordet friluftsliv kom inn i fagplanformuleringene med Mønsterplanen av 1974. 1974 ble derfor valgt som utgangspunkt for studiens søkeperiode, selv om det kan hevdes at opplæring og undervisning som omfatter aktivitet, læring og opphold i natur allerede fra tidlig 1900-tall har vært en del av norsk skoles oppdrag og virke. For søkeperioden fram til 2014 avdekkes 24 studier som møter inklusjonskriteriene, hvorav 18 er master- og hovedfagsoppgaver. Resultatet forteller at foreliggende empirisk basert kunnskap om elevers opplevelser med friluftsliv i skolen er begrenset og ikke tillater å trekke syntetiserte slutninger. Med den reservasjonen som hovedkonklusjon drøfter artikkelen hvilken kunnskap de inkluderte studier kan gi om friluftsliv i skolen ut fra elevers perspektiv.

    2013-01-01

    A 72-year-old man with limited cutaneous systemic scleroderma was hospitalized for two episodes of witnessed syncope. The baseline 12-lead electrocardiogram was normal but on telemetry there were numerous episodes of paroxysmal AV block with asystolic periods of up to 7.5 s duration. Analysis of the rhythm strips revealed phase 4 intra-His bundle block characterized by critical P-P intervals that triggered the AV block, and a narrow range of junctional escape to subsequent P wave intervals that were required to release the AV block. A dual chamber pacemaker was implanted. Copyright © 2013 Elsevier Inc. All rights reserved.

  1. Minimizing ventricular pacing by a novel atrioventricular (AV) delay hysteresis algorithm in patients with intact or compromised intrinsic AV conduction and different atrial and ventricular lead locations.

    Pakarinen, Sami; Toivonen, Lauri

    2013-09-01

    To investigate if an advanced AV search hysteresis (AVSH) algorithm, Ventricular Intrinsic Preference (VIP(™)), reduces the incidence of ventricular pacing (VP) in sinus node dysfunction (SND) with both intact and compromised AV conduction and with intermittent AV block regardless of the lead positions in the right atria and the ventricle. Patients were classified as having intact AV (AVi) conduction if the PR interval was ≤ 210 ms on ECG and 1:1 AV conduction during atrial pacing up to 120 bpm with PR interval ≤ 350 ms. Otherwise the AV conduction was classified as compromised (AVc). Both AVi and AVc patients were randomized to VIP ON or OFF. VIP performed an intrinsic AV conduction search every 30 s for three consecutive atrial cycles with the extension of the sensed and paced AV (SAV/PAV) delays from basic values of 150/200 ms to 300/350 ms. Extended AV intervals were allowed for three cycles when VP occurred before returning to basic AV delays. The primary end-point was %VP at 12 months. Among 389 patients, 30.1% had intact and 69.9% had compromised AV conduction. The mean %VP at 12 months was 9.6% by VIP compared to 51.8% with standard AV settings in patients with AVi (P < 0.0001) and 28.0% versus 78.9% (P < 0.0001) with AVc. With VIP, excessive %VP among most used lead positions was not seen. Conversely, when VIP was off %VP was low only in patients who had leads in the RA septal-RV septal position (23.0%). VIP feature reduces VP both in patients with SND and with intermittent heart block regardless of the lead positions in the right atria and the ventricle.

    Atrioventricular (AV) delay optimization improves hemodynamics and clinical parameters in patients treated with cardiac resynchronization therapy and dual-chamber-pacemakers (PM). However, data on optimizing AV delay in patients treated with VDD-PMs are scarce. We, therefore, investigated the acute and chronic effects of AV delay optimization on hemodynamics in patients treated with VDD-PMs due to AV-conduction disturbances. In this prospective, single-center interventional trial, we included 64 patients (38 men, 26 women, median age: 77 (70-82) years) with implanted VDD-PM. AV-delay optimization was performed using a formula based on the surface electrocardiogram (ECG). Hemodynamic parameters (stroke volume (SV), cardiac output (CO), heart rate (HR), and blood pressure (BP)) were measured at baseline and follow-up after 3 months using impedance cardiography. Using an ECG formula for AV-delay optimization, the AV interval was decreased from 180 (180-180) to 75 (75-100) ms. At baseline, AV-delay optimization led to a significant increase of both SV (71.3 ± 15.8 vs. 55.3 ± 12.7 ml, p AV delay vs. nominal AV interval, respectively) and CO (5.1 ± 1.4 vs. 3.9 ± 1.0 l/min, p AV-delay optimization in patients treated with VDD-PMs exhibits immediate beneficial effects on hemodynamic parameters that are sustained for 3 months.

    Optimization of the AV-interval (AVI) in DDD pacemakers improves cardiac hemodynamics and reduces pacemaker syndromes. Manual optimization is typically not performed in clinical routine. In the present study we analyze the prevalence of E/A wave fusion and A wave truncation under resting conditions in 160 patients with complete AV block (AVB) under the pre-programmed AVI. We manually optimized sub-optimal AVI. We analyzed 160 pacemaker patients with complete AVB, both in sinus rhythm (AV-sense; n = 129) and under atrial pacing (AV-pace; n = 31). Using Doppler analyses of the transmitral inflow we classified the nominal AVI as: a) normal, b) too long (E/A wave fusion) or c) too short (A wave truncation). In patients with a sub-optimal AVI, we performed manual optimization according to the recommendations of the American Society of Echocardiography. All AVB patients with atrial pacing exhibited a normal transmitral inflow under the nominal AV-pace intervals (100%). In contrast, 25 AVB patients in sinus rhythm showed E/A wave fusion under the pre-programmed AV-sense intervals (19.4%; 95% confidence interval (CI): 12.6-26.2%). A wave truncations were not observed in any patient. All patients with a complete E/A wave fusion achieved a normal transmitral inflow after AV-sense interval reduction (mean optimized AVI: 79.4 ± 13.6 ms). Given the rate of 19.4% (CI 12.6-26.2%) of patients with a too long nominal AV-sense interval, automatic algorithms may prove useful in improving cardiac hemodynamics, especially in the subgroup of atrially triggered pacemaker patients with AV node diseases.

    Accessory AV-connections capable of antegrade conduction need to be recognized because of the potential for life-threatening arrhythmias. However, the preexcited ECG pattern may be subtle, especially among left-sided AV-connections. We explored whether additional ECG criteria might help identify left-sided AV-connections. We analyzed 156 patients who underwent an electrophysiology study (EPS) and ablation for paroxysmal supraventricular tachycardias (PSVT). Patients were divided into 2 groups: those with left-sided AV-connections (Group 1) and all other PSVT (Group 2). Various ECG parameters were compared before and after ablation in both groups. The EPS identified left-sided AV-connections among 43 patients (Group 1) and excluded it among 113 (Group 2). Baseline ECG in Group 1 demonstrated obvious preexcitation among 24/43 patients (55.8%), the remaining 19/43 missing obvious preexcitation. R/S ratio > 0.5 in V1 was noted in 38/43 (88.4%) patients in Group 1 before ablation (median 1.00; IQR 0.58-2.20), including 16/19 (84.2%) patients lacking obvious left-sided AVconnections. Conversely, only 10/113 (8.8%) patients in Group 2 had R/S ratios in V1 ≥ 0.5 (0.20; 0.10-0.31), P AV-connections (sensitivity 93.0%). The negative predictive value of this combined criterion was 103/106 (97.2%). In symptomatic patients, combining the R/S ratio (≥ 0.5) in lead V1 with the classic preexcitation pattern on ECG markedly improved the sensitivity to diagnose left-sided AV-connections. This ratio may be particularly useful among patients lacking obvious preexcitation. © 2015 Wiley Periodicals, Inc.

    Full Text Available Abstract: A review of research on children’s development of spatial reasoning in  a preschool setting 1995-2010. This study reviews 16 journal articles, books and theses on spatial reasoning in early childhood mathematics education. The data was collected by way of systematical search in several major databases and relevant digital and non-digital journals. The article gives a brief presentation of the main findings and the different methods used and, if applicable, the authors’ focus on didactics in both method and analysis. When it comes  to children’s mathematical learning processes, a main focus for a majority of studies is children’s use of constructional play material. When it comes to preschool teachers’ work with spatial reasoning, most  studies focus on the teachers’ planned and spontaneous communication with the children. The article then goes on to discuss these findings in relation to the Norwegian Framework Plan for Kindergartens. It seems like future research on the teachers’ use of material, on their work with visualization and orientation, and on their general focus on spatial reasoning could gain curriculum practise. Sammendrag: Denne oversiktsartikkelen gir en presentasjon av 16 internasjonale forskningsarbeider som ser på barns romforståelse i en barnehagekontekst. Arbeidene består av 14 vitenskapelige artikler, en bok og en doktorgrad, og disse ble funnet gjennom systematiske søk i flere større databaser og relevante digitale og analoge tidsskrift. Artikkelen gir en kort presentasjon av de ulike arbeidenes metode, hovedfunn og didaktiske vinkling. Når det gjelder barns utvikling av romforståelse har en majoritet av studiene fokus på hvordan dette kan belyses ved å studere og stimulere barns konstruksjonslek. For de studiene som ser på pedagogens rolle i arbeid med romforståelse legges det mest vekt på kommunikasjon, både planlagt og spontan kommunikasjon. Oversiktsartikkelen drøfter deretter

    Atrioventricular (AV) interval optimization is often deemed too time-consuming in dual-chamber pacemaker patients with maintained LV function. Thus the majority of patients are left at their default AV interval. To quantify the magnitude of hemodynamic improvement following AV interval optimization in chronically paced dual chamber pacemaker patients. A pressure volume catheter was placed in the left ventricle of 19 patients with chronic dual chamber pacing and an ejection fraction >45 % undergoing elective coronary angiography. AV interval was varied in 10 ms steps from 80 to 300 ms, and pressure volume loops were recorded during breath hold. The average optimal AV interval was 152 ± 39 ms compared to 155 ± 8 ms for the average default AV interval (range 100-240 ms). The average improvement in stroke work following AV interval optimization was 935 ± 760 mmHg/ml (range 0-2,908; p AV interval changes the average stroke work by 207 ± 162 mmHg/ml. AV interval optimization also leads to improved systolic dyssynchrony indices (17.7 ± 7.0 vs. 19.4 ± 7.1 %; p = 0.01). The overall hemodynamic effect of AV interval optimization in patients with maintained LV function is in the same range as for patients undergoing cardiac resynchronization therapy for several parameters. The positive effect of AV interval optimization also applies to patients who have been chronically paced for years.

    Permanent AV-block is a recognized and feared complication of slow pathway modulation for AVNRT. We aimed to assess incidence of transient and permanent AV-block as well as consequences of transient AV-block in a large contemporary AVNRT ablation cohort. We searched our single center prospective ablation database for occurrence of transient and permanent AV-block during slow pathway modulation between January 2004 and October 2015. We analyzed patients' and procedural characteristics as well as outcome of patients in whom transient or permanent AV-block occurred. Of 9170 patients who underwent a catheter ablation at our institution between January 2004 and October 2015, 2101 patients (64% women, mean age 50±18years) underwent slow pathway modulation. In three patients, permanent AV-block occurred during RF application. Additional two patients had transient AV-block that recovered (after a few minutes and 25min), but recurred within two days of the procedure. All five patients underwent dual chamber pacemaker implantation (0.2%). Transient AV-block related to RF delivery occurred in 44 patients (2%). Transient mechanical AV-block occurred in additional 17 patients (0.8%). In 12 patients, ablation was continued despite transient AV-block. One of these patients developed permanent AV-block. Permanent AV-block following slow pathway modulation is a rare event, occurring in 0.2% of patients in a large contemporary single center cohort. Transient AV-block is more frequent (2%).

    Slow pathway modification (SPM) is the therapy of choice for AV-nodal reentry tachycardia (AVNRT). When AVNRT is not inducible, empirical ablation can be considered, however, the outcome in patients with two AV nodal echo beats (AVNEBs) is unknown. Out of a population of 3003 patients who underwent slow pathway modification at our institution between 1993 and 2013, we retrospectively included 32 patients with a history of symptomatic tachycardia, lack of paroxysmal supraventricular tachycardia (pSVT) inducibility but occurrence of two AVNEBs. pSVT documentation by electrocardiography (ECG) was present in 20 patients. The procedural endpoint was inducibility of less than two AVNEBs. This was reached in 31 (97%) patients. Long-term success was assessed by a telephone questionnaire (follow-up time 63±9 months). A total 94% of the patients benefited from the procedure (59% freedom from symptoms; 34% improvement in symptoms). Among those patients in whom ECG documentation was not present, 100% benefited (58% freedom from symptoms, 42% improvement). This is the first collective analysis of a group of patients presenting with symptoms of pSVT and inducibility of only two AVNEBs. Procedural success and clinical long-term follow-up were in the range of the reported success rates of slow pathway modification of inducible AVNRT, independent of whether ECG documentation was present. Thus, SPM is a safe and effective therapy in patients with two AVNEBs. Copyright © 2016. Published by Elsevier Ltd.

  4. Mutation of MED12 is not a frequent occurrence in prostate cancer of Korean patients

    2017-01-01

    Full Text Available Prostate cancer is one of the major health care problems, but the molecular pathogenesis has been relatively insufficiently elucidated. Recently, whole exome sequencing of prostate cancer identified recurrent mutations involving MED12 in Caucasian patients, which finding was not reproduced in one subsequent study by Sanger sequencing. Thus, we investigated mutation status of MED12 in exons 2 and 26 by Sanger sequencing in 102 radical prostatectomy cases from Korean patients. The analysis found the mutation in none of the cases. Therefore, MED12 mutation does not appear to represent a significant molecular alteration in this cohort of patients according to the analysis by the traditional "gold standard."

    Full Text Available Substance abuse, anxiety and depression after 10 years: A prospective study of drug users in and outside OMT treatment AIMS - The national Opiate Maintenance Treatment (OMT program in Norway started officially in 1998. The same year a treatment study was initiated, including the most used treatment measures for drug users in Norway. The main aim in the present study was to investigate the prevalence of live OMT patients in the total sample after 10 years, and to compare the outcome of primarily substance abuse, anxiety and depression among OMT patients versus non-OMT patients. DESIGN & METHODS - Four hundred and seven patients, in Oslo and the nearby regions, who started in 16 different in- and outpatients programs, were followed from intake to treatment and during ten years (1998-2009. Patients in the sample were interviewed after one, two, seven and ten years, and they were divided into three different treatment groups: inpatient residency for grown-ups, outpatient psychiatric youth teams and youths living in collectives. Data was collected through use of EuropASI and HSCL-25 at all follow-ups. RESULTS - After ten years 15 % were deceased. Of the 333 persons left, 73 % (n=248 were interviewed after ten years. Forty percent (n=99 were then in OMT. After ten years there were no gender differences regarding attendance to OMT, but the OMT-group was older (30 vs .28 yrs, p<0.05, and they used more benzodiazepines (p<0.000 and cannabis (p<0.01 than the others. The OMT-group reported to a larger extent more anxiety and depression throughout the total observation period than the non OMT participants. Use of heroin and criminality were significantly reduced in both groups. CONCLUSIONS - In spite of reduced use of heroin, the OMT patients seemed to have more difficulties in reducing the use of benzodiazepines and cannabis, whereas the anxiety and depression scores were high and stable through the total observation time.

    Somatic mutations in mediator complex subunit 12 (MED12) have emerged as a critical genetic change in the development of uterine leiomyomas. Studies, however, have focused largely on cohorts consisting of Caucasian patients. In this study, uterine leiomyomas from Chinese patients were examined for MED12 mutations. In addition, polymerase chain reaction (PCR)-based high-resolution melting analysis (HRMA) was compared with direct sequencing as a potentially more sensitive method for the detection of MED12 mutations. Tissue samples with the pathologies of uterine leiomyoma (n=181) and other endometrial diseases (n=157) were collected from Chinese patients at the Taizhou People's Hospital and Taizhou Polytechnic College (Taizhou City, China). Genomic DNA was prepared from all samples. Both PCR-based HRMA and PCR-based direct sequencing were used to detect MED12 mutations. PCR-based HRMA and direct sequencing revealed MED12 mutations in 95/181 (52.5%) and 93/181 (51.4%) uterine leiomyomas, respectively. Nearly half of these mutations (46/93) were found in a single codon, codon 131. The coincidence rate between the two methods was 98.9% (179/181) so that no statistically significant difference was evident in the application of the methodologies (χ(2)=0.011, p=0.916). In addition, MED12 mutations were identified in 1/157 (4.17%) case of other endometrial pathologies by both methods. MED12 mutations were closely associated with the development of uterine leiomyomas, as opposed to other uterine pathologies in Chinese patients, and PCR-based HRMA was found to be a reliable method for the detection of MED12 mutations.

    Patients with implanted SynchroMed spinal infusion pumps (Medtronic, Inc., Minneapolis, MN) routinely undergo magnetic resonance imaging at our institution. In August 2008, Medtronic issued an urgent medical device correction report regarding several pumps. Because of the rare potential ''for a delay in the return of proper drug infusion'' and ''for a delay in the logging of motor stall events,'' ''a patient's pump must be interrogated after MRI exposure in order to confirm proper pump functionality.'' This is particularly important in patients receiving intrathecal baclofen, for whom a delay in return of proper pump infusion could lead to life-threatening baclofen withdrawal syndrome. The objective of this report is to present our experience and protocol of performing magnetic resonance imaging in patients with implanted SynchroMed EL pumps. We retrospectively reviewed records of 86 patients with implanted SynchroMed EL spinal infusion pumps who underwent 112 examinations on 1.5-T magnetic resonance imaging scanners from September 1, 1998 to July 7, 2004. No SynchroMed EL pumps were damaged by magnetic resonance imaging, and the programmable settings remained unchanged in all patients. Our data suggest that SynchroMed EL pump malfunction is indeed rare after routine clinical 1.5-T magnetic resonance imaging examinations. However, based on the Medtronic correction report, we perform pump interrogation before and after imaging. (orig.)

    Many patients recently discharged from an asthma admission do not fill discharge prescriptions. If unable to adhere to a discharge plan, patients with asthma are at risk for re-presentation to care. We sought to increase the proportion of patients discharged from an asthma admission in possession of their medications (meds in hand) from a baseline of 0% to >75%. A multidisciplinary improvement team performed 3 plan-do-study-act cycles over 2 years and, using a statistical process control chart, tracked the proportion of patients admitted with asthma discharged with meds in hand as the primary outcome. An exploratory, retrospective analysis of insurance data was conducted with a convenience sample of Medicaid-insured patients, comparing postdischarge utilization between patients discharged with meds in hand and usual care. Generalized estimating equations accounted for nonindependence in the data. Changes to the discharge process culminated in the development of a discharge medication delivery service. Outpatient pharmacist delivery of discharge medications to patient rooms achieved the project aim of 75% of patients discharged with meds in hand. In a subset of patients for whom all insurance claims were available, those discharged with meds in hand had lower odds of all-cause re-presentation to the emergency department within 30 days of discharge, compared with patients discharged with usual care (odds ratio, 0.22; 95% confidence interval, 0.05-0.99). Our initiative led to several discharge process improvements, including the creation of a medication delivery service that increased the proportion of patients discharged in possession of their medications and may have decreased unplanned visits after discharge.

    The EVOCAV(DS) trial aimed to quantify the paradoxal atrioventricular (AV) conduction time lengthening in sinus node (SD) patients (pts) paced in AAIR-based pacing mode. SD pts, implanted with dual-chamber pacemaker programmed in AAIR-based pacing mode, were randomized in two arms for a 1-month period: the low atrial pacing (LAP; basic rate at 60 bpm, dual sensor with minimal slope) and the high atrial pacing (HAP; basic rate at 70 bpm, dual sensor with optimized slope, overdrive pacing) arm. At 1 month, crossover was performed for an additional 1-month period. AV conduction time, AV block occurrence and AV conduction time adaptation during exercise were ascertained from device memories at each follow-up. Seventy-nine pts participated to the analysis (75 ± 8 years; 32 male; PR = 184 ± 38 ms; bundle branch block n = 12; AF history n = 36; antiarrhythmic treatment n = 53; beta-blockers n = 27; class III/Ic n = 18; both n = 8). The mean AV conduction time was significantly greater during the HAP (275 ± 51 ms) vs. LAP (263 ± 49 ms) period (p AV blocks occurred in 49 % of pts in the HAP vs. 19 % in the LAP period (p AV conduction time during exercise. AAIR-based pacing in SD pts may induce a significant lengthening of pts' AV conduction time, including frequent abnormal adaptation of AV conduction time during exercise.

  18. Crowdsourcing Diagnosis for Patients With Undiagnosed Illnesses: An Evaluation of CrowdMed.

    2016-01-14

    Despite visits to multiple physicians, many patients remain undiagnosed. A new online program, CrowdMed, aims to leverage the "wisdom of the crowd" by giving patients an opportunity to submit their cases and interact with case solvers to obtain diagnostic possibilities. To describe CrowdMed and provide an independent assessment of its impact. Patients submit their cases online to CrowdMed and case solvers sign up to help diagnose patients. Case solvers attempt to solve patients' diagnostic dilemmas and often have an interactive online discussion with patients, including an exchange of additional diagnostic details. At the end, patients receive detailed reports containing diagnostic suggestions to discuss with their physicians and fill out surveys about their outcomes. We independently analyzed data collected from cases between May 2013 and April 2015 to determine patient and case solver characteristics and case outcomes. During the study period, 397 cases were completed. These patients previously visited a median of 5 physicians, incurred a median of US $10,000 in medical expenses, spent a median of 50 hours researching their illnesses online, and had symptoms for a median of 2.6 years. During this period, 357 active case solvers participated, of which 37.9% (132/348) were male and 58.3% (208/357) worked or studied in the medical industry. About half (50.9%, 202/397) of patients were likely to recommend CrowdMed to a friend, 59.6% (233/391) reported that the process gave insights that led them closer to the correct diagnoses, 57% (52/92) reported estimated decreases in medical expenses, and 38% (29/77) reported estimated improvement in school or work productivity. Some patients with undiagnosed illnesses reported receiving helpful guidance from crowdsourcing their diagnoses during their difficult diagnostic journeys. However, further development and use of crowdsourcing methods to facilitate diagnosis requires long-term evaluation as well as validation to account

    Adaptive cardiac resynchronization therapy (aCRT) is a dynamic optimization algorithm which paces only the left ventricle (LV) when atrio-ventricular (AV) conduction is normal, thus reducing right ventricular (RV) pacing. However, the impact of QRS duration on aCRT efficacy remains uncertain. We examined whether QRS duration impacts aCRT effectiveness in patients with left bundle branch block (LBBB) and preserved AV conduction. Randomized patients in the Adaptive CRT trial, which enrolled NYHA III/IV patients, were used in this analysis. Patients were randomized to receive aCRT or echo-optimized bi-ventricular CRT (control arm). Endpoints for this analysis were clinical composite score (CCS) at 6months post-implant and time to first heart failure (HF) hospitalization or death. Among the 199 patients with LBBB and normal AV intervals at baseline, 80 patients (40%) had a baseline moderately wide QRS of 120-150ms. In this subgroup, a greater proportion of aCRT patients had an improved CCS (79% vs. 50%) at 6months compared to the control group (p=0.03). There was also a trend toward a lower risk of death or HF hospitalization (hazard ratio: 0.53; 95% CI: 0.24-1.15; p=0.10) in the moderately wide QRS subgroup with aCRT compared to the control arm. In the wide QRS subgroup, the efficacy was comparable in both treatment arms. Adaptive CRT was associated with improved patient outcomes over echo-optimized bi-ventricular CRT in patients with preserved AV conduction, LBBB, and moderately wide QRS.

    2016-01-01

    There is significant, unexploited potential to improve the patients' engagement in psychotherapy treatment through technology use. We develop Tele-Board MED (TBM), a digital tool to support documentation and patient-provider collaboration in medical encounters. Our objective is the evaluation of TBM's practical effects on patient-provider relationships and patient empowerment in the domain of talk-based mental health interventions. We tested TBM in individual therapy sessions at a psychiatric ward using action research methods. The qualitative results in form of therapist observations and patient stories show an increased acceptance of diagnoses and patient-therapist bonding. We compare the observed effects to patient-provider relationship and patient empowerment models. We can conclude that the functions of TBM - namely that notes are shared and cooperatively taken with the patient, that diagnostics and treatment procedures are depicted via visuals and in plain language, and that patients get a copy of their file - lead to increased patient engagement and an improved collaboration, communication and integration in consultations.

    A number of studies argue in favour of an important role of microbial colonization, in particular of Staphylococcus aureus, in triggering atopic dermatitis (AD) flare-up and psoriasis, in particular through the superantigenic properties of toxins generated by S. aureus. The aim of this study was to assess the efficacy of a 3-week Avène hydrotherapy on the skin surface of patients suffering from psoriasis or atopic dermatitis. Skin samples were taken from healthy subjects or atopic (n = 18) or psoriatic patients (n = 39) undergoing hydrotherapy at Avène at the beginning (D0) and the end of treatment (D18). The severity of the dermatosis was evaluated according to SCORing Atopic Dermatitis (SCORAD) or Psoriasis Area Severity Index (PASI) scores at D0 and D18. Marker of inflammation interleukin 8 (IL-8), S. aureus colonization (protein A) and enterotoxins were assessed in skin samples using RT-PCR. At D0, significant differences were observed between healthy subjects and atopic or psoriatic patients in all the parameters evaluated (IL-8, protein A). At the end of the hydrotherapy, a significant decrease in SCORAD was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin D in patients with atopic dermatitis. Similarly, a significant decrease in PASI was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin N in patients with psoriasis. This study demonstrates the positive effects of Avène hydrotherapy on the skin of patients suffering from chronic dermatosis, with decreased inflammation and reduced colonization by S. aureus. © 2010 The Authors.

    Thrombosis of native arteriovenous (AV) fistula is an important cause of complications in hemodialysis (HD) patients. The purpose of this study was to investigate the usefulness of measuring circulating fibroblast growth factor-23 (FGF-23) level and paraoxonase-1 (PON1) lactonase activity as potential predictors of native AV fistula thrombosis in chronic HD patients. This study included 83 HD patients (48 with thrombosed and 35 with non-thrombosed native AV fistulas) and 38 healthy volunteers. Serum FGF-23 level was measured using the ELISA technique, while serum PON1 lactonase activity was measured spectrophotometrically using gamma-thiobutyrolactone as a substrate. FGF-23 was significantly increased while PON1 lactonase was markedly decreased in both thrombosed and non-thrombosed HD patients compared with controls (P AV fistulas compared with HD patients with non-thrombosed native AV fistulas (P = 0.001 and 0.002, respectively). A significant negative correlation was found between FGF-23 and PON1 lactonase in HD patients with thrombosed native AV fistulas (r = -0.342, P = 0.017). This study shows a potential value of FGF-23 and PON1 lactonase as predictors of native AV fistula thrombosis in HD patients.

Pregnant women with epilepsy have increased risk for certain obstetricalcomplications, and for giving birth to children with congenital malformations. The increased risk forcongenital malformations seems connected to the use of AED, not to the epileptic syndromes. The etiologyof congenital malformations are multifactorial. Use of AED in monotherapy is associated with anindividual risk of giving birth to a child with a major malformation of 4-6%.

    Patients with a pacing indication and first-degree atrioventricular (AV)-block pose a clinical challenge. The prognostic impact of first-degree AV-block in patients with sinus node dysfunction and the impact of pacing in this setting are not known. In the Mode Selection Trial (MOST), 2,010 patients with sinus node dysfunction were randomized to either dual-chamber (DDD-R) or ventricular (VVI-R) pacing and followed for a median of 33 months. We report on clinical outcomes in patients with first-degree AV-block (PR interval > 200 ms) compared with patients who had a normal PR interval at baseline. Patients with first-degree AV-block (n = 378) were older (median [Q1, Q3]; 76 [70, 82] years vs 73 [66, 79] years, PAV-conduction (n = 1,159). In multivariable analyses, patients with first-degree AV-block were at greater risk of death, stroke, or heart failure hospitalization (hazard ratio [HR] 1.31, 95% confidence interval [CI] 1.06-1.61, P = 0.013). A trend towards a higher incidence of atrial fibrillation was seen (HR 1.24, 95% CI 0.98-1.55, P = 0.069). No significant interactions between pacing arm and prolonged versus normal PR were found for any endpoint, and hazard ratios were consistent across subgroups. First-degree AV-block is associated with more advanced disease but is still an independent predictor of poor clinical outcome. Neither DDD-R nor VVI-R pacing, as employed in MOST, eliminate the negative effects associated with first-degree AV-block. ©2014 Wiley Periodicals, Inc.

    Activated glutaraldehyde (2%) is the recommended agent for disinfection of endoscopic equipment. Exposure to the disinfectant is associated with side-effects and guidelines have been set to avoid these complications. Endoscope washing machines are used to provide automated high level disinfection of endoscopes as well as reduce exposure to the irritant aldehyde. We report a design fault in an endoscope washing machine which results in patients and staff being exposed to activated glutaraldehyde. The Auto-Disinfector (KeyMed) comprises a washing chamber supplied by three separate reservoirs (detergent, disinfectant, and rinse water) via a common channel. After the first cycle endoscopes are processed using previously used detergent and rinse water. Rinse water glutaraldehyde concentrations were measured in four machines during routine endoscopy lists on at least two occasions and showed a progressive rise in glutaraldehyde concentration up to 0.1% after two to six cycles. This results in staff being exposed to glutaraldehyde present on the processed instrument and the disinfectant being pumped from the internal channels of the endoscope into direct contact with the gastrointestinal mucosa during endoscopy at concentrations of 200-1000 ppm. The present atmospheric limit for glutaraldehyde is 0.2 ppm. Skin and mucosal irritation occur at concentrations of 0.3 ppm and severe synovitis in experimental animals at 100 pm. Tongue swelling and bloody diarrhoea with characteristic mucosal histological changes have been reported in patients exposed to activated glutaraldehyde on inadequately rinsed equipment. To reduce this problem the rinse water should be changed after every cycle and the endoscope should be dried thoroughly before use.

    Atopic dermatitis and psoriasis engender a significant deterioration in patients' quality of life. Although the efficacy of patient management at the Avène hydrotherapy centre has been demonstrated by clinical studies, few data relating to changes in the quality of life following therapeutic management are available. The objective of this study was to evaluate the short- and medium-term effects of hydrotherapy not only on the patients' quality of life, but also on the quality of life of the parents of the treated children. In this 6-month longitudinal observational study, adult (n = 174) and paediatric (n = 212) atopic patients and psoriatic patients (n = 262) had to complete questionnaires relating to the quality of life at the beginning (D0) and after 3 weeks hydrotherapy (W3), and then, 3 (M3) and 6 months (M6) later. The dermatology life quality index (DLQI) and the Short-Form-12 Health Survey (SF-12) generic questionnaire were given to adult patients. The children's dermatological life quality index (CDLQI) was given to paediatric patients, and the SF-12 to their parents. At D0, the DLQI score was 29.7 ± 20.1 and 26.9 ± 18.9 for atopic and psoriatic patients, respectively. At W3, this score had decreased significantly to reach 16.8 ± 14.9 (P hydrotherapy centre significantly improved the quality of life of patients suffering from skin diseases. This improvement persisted 3 and 6 months after management by hydrotherapy. © 2010 The Authors. JEADV © 2010 European Academy of Dermatology and Venereology.

Svevestøvet kan deles inn i størrelsesfraksjoner som PMAmbient particulate matter (PM comprises particles from different combustion processes and a variety of mineral particles. The particles vary widely in size distribution and chemical/physical characteristics. PM is often divided into size fractions with different aerodynamic diameters: PM10 (PM ! 10 mm, PM2.5 (PM ! 2.5 mm and PM0.1 (PM ! 0.1 mm. Recent population studies have found an association between an increase in mortality and morbidity due to lung and/or cardiovascular disease and short-term increases in PM. The relative risk (RR was approximately 1.005 for an increase in 10 mg/m3 PM10, without an observed threshold even at concentrations below 10 mg/m3. Chronic exposure has been investigated to a lesser extent, but longterm exposure to PM2.5 has been found to be associated with an approximately 10-fold greater increase in RR than short-term exposures. Experimental studies with volunteers in chamber and field studies show mild lung or cardiovascular responses at concentrations of ambient particles (PM2.5/PM10: 100-200 mg/m3 that may occur during episodes of air pollution. Animal studies at higher concentrations have shown stronger responses. The experimental studies support the epidemiological evidence for an adverse health effect of PM. Both population- and experimental studies indicate the existence of vulnerable individuals. At low to average ambient concentrations there seems to exist a discrepancy between the results of population- and experimental studies that might be due to the absence of the most vulnerable individuals in the experimental studies. Together with cell culture experiments, human and animal studies indicate the importance of physical and chemical properties of the particles (size, content of metals, organics, endotoxins, etc. for

    2014-01-01

    Full Text Available Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT occurs due to concurrent antegrade conduction over fast and slow atrioventricular nodal pathways and is treated by slow pathway modification. We describe a unique case of a patient with cardiac sarcoidosis who received inappropriate ICD shocks for DAVNNT. Atrial and ventricular device electrograms satisfied both rate and V>A criteria for ventricular tachycardia. We postulate that alterations in refractoriness and conduction as is seen in cardiac sarcoidosis (CS may have contributed to occurrence of DAVNNT.

    2014-07-01

    We hypothesized that left atrial pressure (LAP) obtained by a permanent implantable sensor is sensitive to changes in cardiac resynchronization therapy (CRT) settings and could guide CRT optimization to improve the response rate. We investigated the effect of CRT optimization on LAP and its waveform parameters in ambulant heart failure (HF) patients. CRT optimization was performed in eight ambulant HF patients, using echocardiography as reference. LAP waveform was acquired at each of eight atrioventricular (AV) intervals and five inter-ventricular (VV) intervals. Selected waveform parameters were also evaluated for their sensitivity to CRT changes and agreement with echocardiography-guided optimal settings. Optimal AV and VV intervals varied considerably between patients. All patients exhibited significant changes in waveform morphology with AV optimization. Optimal AV delay determined from echocardiography ranged between 140 ms and 225 ms. Mean LAP tended to be lower at optimal setting 14 ± 3 mmHg compared to shorter (160 ms) AV settings (P = 0.16). There were clear trends to smaller peak a-wave (P = 0.11) and gentler positive a-slope (P = 0.15) and positive v-slope (P = 0.09) with longer AV delays. Mean LAP and negative v-wave slope correlated well with echo-guided optimal setting, r = 0.91 (P = 0.001) and 0.79 (P = 0.03), respectively. No significant effects on LAP or waveform were seen during VV optimization. LAP and its waveform changes considerably with AV optimization. There is good agreement between echo-guided optimal setting and LAP. LAP could provide an objective guide to CRT optimization.

  15. Arvelig hemokromatose - nytten av screening

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Arvelig hemokromatose fører til jernopphopning i kroppen, men gir sjelden alvorlig helseskade. Nesten alle hemokromatosepasienter i vårt land er homozygote for C282Y-mutasjonen i HFE-genet. Omtrent 7 per 1000 innbyggere har denne genotypen. Alvorlig syke blir bare omkring 5-15% av homozygote menn og nesten ingen kvinner. Likevel er det holdepunkter for at screening for hemokromatose blant friske, yngre menn kan være kostnadseffektivt. Det er relativt lett å påvise om en person er disponert for sykdommen, i god tid før den bryter ut, og forebyggende behandling er billig og effektiv. Imidlertid kan vi ikke forutsi hvilke screeningpositive personer som ubehandlet får alvorlig sykdom. Et kontrollert forsøk med screening bør gjennomføresHereditary hemochromatosis – benefits of screening. Hereditary hemochromatosis leads to iron accumulation in the body; however, serious illness due to hemochromatosis is rare. In Norway, almost all patients with hemochromatosis are homozygous for the C282Ymutation in the HFE-gene, a genotype carried by about 7 per 1000 inhabitants. Serious complications are seen in only about 5-15% of homozygous men and in very few women. Nevertheless, screening young men for hemochromatosis may be cost-effective. Detecting predisposed men is relatively straightforward, and prophylactic treatment is cheap and effective. However, we can not predict, among screen-positive men, the few who untreated will become seriously ill. A controlled screening trial should be conducted.

    (99m)Tc-TRODAT-1 is the first clinical routine (99m)Tc radiopharmaceutical to evaluate dopamine neurons loss in Parkinson's disease (PD). (18)F-AV-133 is a novel PET radiotracer targeting the vesicular monoamine transporter type 2 (VMAT2) to detect monoaminergic terminal reduction in PD patients. The aim of this study is to compare both images in the same health control (HC) and PD subjects. Eighteen subjects (8 HC and 10 PD) were recruited for (99m)Tc-TRODAT-1 SPECT, (18)F-AV-133 PET and MRI scans within two weeks. The SPECT images were performed at 4-h post-injection for 45 min, and the PET images were performed at 90 min post-injection for 10 min. Each PET and SPECT image was normalized into Montreal Neurological Institute template aided from individual MRI for comparison. For regional analysis, volume of interest (VOIs) of bilateral caudate nuclei, anterior, posterior putamen and occipital cortex (as reference region) were delineated from the normalized MRI. The specific uptake ratio (SUR) was calculated as (regional mean counts/reference mean counts-1). The nonparametric Mann-Whitney U test was used to evaluate the power of differentiating control from PD subjects for both image modalities. The correlations of the SURs to the clinical parameters were examined. For voxelwise analysis, two-sample t-test for group comparison between HC and PD was computed in both image modalities. The SURs of caudate nucleus and putamen correlated well between two image modalities (r = 0.81, pAV-133 SUR displayed a better correlation to PD clinical laterality index as compared to (99m)Tc-TRODAT-1 (r = 0.73 vs. r = 0.33). Voxelwise analysis showed more lesions for PD subjects from (18)F-AV-133 image as compared to (99m)Tc-TRODAT-1 especially at the substantia nigra region. (18)F-AV-133 PET demonstrated similar performance in differentiation PD from control, and a better correlation to clinical characteristics than that of (99m)Tc-TRODAT-1 SPECT. (18)F-AV-133 PET also showed

    2005-07-01

    AVS is a new digital audio-video coding standard established by China. AVS will be used in digital TV broadcasting and next general optical disk. AVS adopted many digital audio-video coding techniques developed by Chinese company and universities in recent years, it has very low complexity compared to H.264, and AVS will charge very low royalty fee through one-step license including all AVS tools. So AVS is a good and competitive candidate for Chinese DTV and next generation optical disk. In addition, Chinese government has published a plan for satellite TV signal directly to home(DTH) and a telecommunication satellite named as SINO 2 will be launched in 2006. AVS will be also one of the best hopeful candidates of audio-video coding standard on satellite signal transmission.

    Background: Studies have shown that use of nursing diagnoses can improve quality of documented assessments, quality of described interventions and outcomes, and that they facilitate communication and continuity between practitioners in the health care services. Collaboration between a hospital and a university college was established to study the implementation of nursing diagnoses. Purpose: This study intends to investigate the feasibility of the study and the experiences nurses in clinical practice have after an implementation of nursing diagnoses. Method: A focus group interview with six participants was conducted. The researchers’ experiences upon the intervention feasibility were logged as notes. Results: The participants found the intervention helpful and educational, but also frustrating. Nursing diagnoses seems to be useful in clinical work, but the intervention period may have been too short to achieve changes in the documentation work. Conclusion: There is need for further studies so that nursing documentation can be a good tool to support nurses in their working process.

Moreover, longitudinal studies indicate that weight reduction improves asthma control. Therefore, preventing and treating obesity should be an integrated part of asthma management....

    2011-01-01

    In this systematic review of the literature, we reviewed the evidence for maintaining the current recommendation that a routine CT scan should be performed in first-episode psychotic patients (Danish National Board of Health). We identified eight papers comprising 625 CT and 214 MRI scans....... The share of potentially causal brain abnormalities was 0.8% with CT and 3.3% with MRI, but the findings had limited clinical consequences. We concluded that there is no evidence in support of performing routine CT scans of first-episode psychotic patients. If intracranial pathology is suspected clinically......, an MRI scan should be performed....

    UpToDate and PubMed are popular sources for medical information. Data regarding the efficiency of PubMed and UpToDate in daily medical care are lacking. The purpose of this observational study was to describe the percentage of answers retrieved by these information sources, comparing search results with regard to different medical topics and the time spent searching for an answer. A total of 40 residents and 30 internists in internal medicine working in an academic medical center searched PubMed and UpToDate using an observation portal during daily medical care. The information source used for searching and the time needed to find an answer to the question were recorded by the portal. Information was provided by searchers regarding the topic of the question, the situation that triggered the question, and whether an answer was found. We analyzed 1305 patient-related questions sent to PubMed and/or UpToDate between October 1, 2005 and March 31, 2007 using our portal. A complete answer was found in 594/1125 (53%) questions sent to PubMed or UpToDate. A partial or full answer was obtained in 729/883 (83%) UpToDate searches and 152/242 (63%) PubMed searches (P UpToDate answered more questions than PubMed on all major medical topics, but a significant difference was detected only when the question was related to etiology (P UpToDate and 291 seconds (SD 7) for PubMed. Specialists and residents in internal medicine generally use less than 5 minutes to answer patient-related questions in daily care. More questions are answered using UpToDate than PubMed on all major medical topics.

We compared 4 protocols for comparing dp/dtmax between AV delays:Immediate absolute: mean of 10 s recording of dp/dtmax acquired immediately after programming the tested AVD,Delayed absolute: mean of 10 s recording acquired 30 s after programming AVD,Single relative: relative difference between reference AVD and the tested AVD,Multiple relative: averaged difference, from multiple alternations between reference and tested AVD. We assessed for dp/dtmax, LVSBP and LVPP, test–retest reproducibility of the optimum. Optimization using immediate absolute dp/dtmax had poor reproducibility (SDD of replicate optima = 41 ms; R2 = 0.45) as did delayed absolute (SDD 39 ms; R2 = 0.50). Multiple relative had better reproducibility: SDD 23 ms, R2 = 0.76, and (p AV delay was LVSBP 2% and LVdp/dtmax 5%, while CRT with pre-determined optimal AVD gave 6% and 9% respectively. Conclusions Because of inevitable background fluctuations, optimization by absolute dp/dtmax has poor same-day reproducibility, unsuitable for clinical or research purposes. Reproducibility is improved by comparing to a reference AVD and making multiple consecutive measurements. More than 6 measurements would be required for even more precise optimization — and might be advisable for future study designs. With optimal AVD, instead of nominal, the hemodynamic increment of CRT is approximately doubled. PMID:23481908

    Full Text Available Artikkelen er skriven på bakgrunn av problematikk kring utvikling av ein forskingsbasert didaktikk for tekstilundervisninga på grunnstudiet ved Institutt for folkekultur, Høgskolen i Telemark. Delar av forskingsprosjektet tek difor utgangspunkt i eksisterande undervisnings­verksemd ved dette studiet. Spørsmåla som det er søkt å få svar på her, er: Kva dialog og læri­ng er framtredande ved kopiering av ein tradisjonell tekstilgjenstand? og: Korleis har denne arbeidsmåten ein plass i ein forskingsbasert didaktikk? Kopiprosessen skjedde i ein avgrensa oppgåveperiode, utført med to studentgrupper i 2008/2009. Intervju var valt som me­to­de saman med analyse av innhald i oppgåverapportar som var skrivne samtidig med kopiverksemda. I samband med utvikling av ein forskingsbasert didaktikk der kopiverksemd inngår, er drøftingane førte på grunnlag av sosiokulturell og sløydpedagogisk teori, saman med teori i møte med folkekunst. Kopiprosessen er relatert til ein verksemdsmodell for sløydfaget. Resultata er drøfta i høve til mål for oppgåva og gjeldande fagplan. Kopiering som læringsmetode har ein plass i ein forskingsbasert didaktikk når verksemda fører til erkjenning og integrert forståing, ikkje som rekonstruksjon av tradisjonar. Målet for ein forsk­ings­­basert didaktikk er horisontsamansmelting som følgje av hermeneutiske samtaler som gjeld samspel, spatialitet, spelereglar og spelerom i tradisjonen.

    AV-45 amyloid biomarker is known to show uptake in white matter in patients with Alzheimer's disease (AD), but also in the healthy population. This binding, thought to be of a non-specific lipophilic nature, has not yet been investigated. The aim of this study was to determine the differential pattern of AV-45 binding in white matter in healthy and pathological populations. We recruited 24 patients presenting with AD at an early stage and 17 matched, healthy subjects. We used an optimized positron emission tomography-magnetic resonance imaging (PET-MRI) registration method and an approach based on an intensity histogram using several indices. We compared the results of the intensity histogram analyses with a more canonical approach based on target-to-cerebellum Standard Uptake Value (SUVr) in white and grey matter using MANOVA and discriminant analyses. A cluster analysis on white and grey matter histograms was also performed. White matter histogram analysis revealed significant differences between AD and healthy subjects, which were not revealed by SUVr analysis. However, white matter histograms were not decisive to discriminate groups, and indices based on grey matter only showed better discriminative power than SUVr. The cluster analysis divided our sample into two clusters, showing different uptakes in grey, but also in white matter. These results demonstrate that AV-45 binding in white matter conveys subtle information not detectable using the SUVr approach. Although it is not more efficient than standard SUVr in discriminating AD patients from healthy subjects, this information could reveal white matter modifications. (orig.)

    Full Text Available Artikkelen gir et praktisk eksempel på hvordan ulike studentgrupper i forbindelse med bygging av nødbivuakk i vinterfjellet opplevde min situasjonsbestemte ledelse som veileder. Teorigrunnlaget viser til situasjonsbestemte ledelsesmodeller og hva som kjennetegner god veiledning i friluftsliv. Datainnsamlingen bygger på kvantitative data fra et spørreskjema og benyttes til å analysere studentenes opplevelse av veileders ledelse ut i fra rangeringsmetoden Visuell Analog Skala (VAS. Fra samme spørreskjema var det også et åpent spørsmål som benyttes til refleksjon over studentenes opplevelse av sikkerhet i undervisningssituasjonen. Resultatene viser at studentgruppene opplevde klare ledelsesforskjeller gjennom de ulike fasene som ledelsen ble delt opp i, men at ledelsesatferden varierte lite i forhold til gruppenes erfaringsgrunnlag. Resultatene tyder på at jeg som veileder i stor grad har blitt påvirket av mine tidligere erfaringer og den potensielle risikoen som ligger ved aktiviteten. Selv om den situasjonsbestemte ledelsen varierte lite mellom de tre gruppene, viser resultatenes store standardavvik at de ulike smågruppene opplevde at ledelsen varierte. Dette tyder på at jeg som veileder til en viss grad har evnet å benytte situasjonsbestemt ledelse i praksis. På grunn av studentgruppenes relativt like oppfatning av ledelsen i de ulike fasene, viser resultatene også noe av vanskelighetene veileder har i forhold til å gjøre en korrekt vurdering av gruppens evner og erfaring i relasjon til læringssituasjonene som oppstår. Sentralt for ledelsen er likevel at studentgruppene opplevde ledelsen som betryggende, noe som gir studentene et godt grunnlag for senere opplevelser i tilknytning til vinterfriluftsliv og bygging av nødbivuakk.

    Atopic dermatitis (AD) and psoriasis are chronic skin conditions. Local or systemic treatments are effective, but their effects are transient. Hydrotherapy, used alone or in combination with other treatments, could be considered as one form of care in providing effective management of these dermatoses. The objective of this observational study was to evaluate the benefit of a 3-week treatment at Avène Hydrotherapy Centre in a very large cohort of patients suffering from atopic dermatitis and psoriasis and to assess the treatment benefits on patients undergoing hydrotherapy for two consecutive years. This 8-year observational study analysed 14,328 records of patients having a dermatological disease and who came to Avène Hydrotherapy Centre for a 3-week treatment between 2001 and 2009. Among them, patients were suffering from atopic dermatitis (n = 5916) and psoriasis (n = 4887). On admission on D0 (day 0) and at the end of cure on D18 (day 18), the severity of AD and psoriasis were evaluated by SCORing Atopic Dermatitis (SCORAD) and Psoriasis Area and Severity Index (PASI), respectively. In order to assess the cumulative effect of the hydrotherapy treatment, the evolution of SCORAD or PASI of patients who came 2 years in a row was also calculated. A significant improvement in SCORAD was observed between D0 and D18 (-41.6%) (P hydrotherapy. PASI 50 and PASI 75 were 64.3% and 19.5%, respectively. For atopic patients (n = 1102) or patients suffering from psoriasis (n = 833) who came for two consecutive years, a significant SCORAD and PASI improvement was observed on D0 of the second year when compared with D0 of the previous year (P Hydrotherapy Centre for atopic and psoriatic patients. © 2010 The Authors.

    2015-08-01

    Syncope due to idiopathic AV block is characterized by: 1) ECG documentation (usually by means of prolonged ECG monitoring) of paroxysmal complete AV block with one or multiple consecutive pauses, without P-P cycle lengthening or PR interval prolongation, not triggered by atrial or ventricular premature beats nor by rate variations; 2) long history of recurrent syncope without prodromes; 3) absence of cardiac and ECG abnormalities; 4) absence of progression to persistent forms of AV block; 5) efficacy of cardiac pacing therapy. The patients affected by idiopathic AV block have low baseline adenosine plasma level values and show an increased susceptibility to exogenous adenosine. The APL value of the patients with idiopathic AV block is much lower than patients affected by vasovagal syncope who have high adenosine values. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Medisinsk forskning har ført til store framskritt de siste tiårene. Det er investert mye mer ressurser på basalforskning og klinisk forskning enn på å utvikle og evaluere metoder for å sikre at pasientene får nytte av forskningen. Formålet med implementeringsforskning er å redusere gapet mellom forskning og praksis, ved å utvikle og evaluere tiltak som kan sikre at behandlingen som pasientene mottar er kunnskapsbasert, at den er omsorgsfull og av god kvalitet.I denne artikkelen gjør vi rede for hva implementering og implementeringsforskning er. Vi belyser historikken til denne unge vitenskapen, og illustrerer mangfoldet i de faglige tilnærmingene og begrepene som brukes om det å få forskning brukt i praksis. Det finnes en rekke teorier om endring av atferd, både på individnivå og på organisatorisk nivå. Teoriene er imidlertid i liten grad testet empirisk, særlig når det gjelder å endre atferd i helsetjenesten.Systematiske oversikter over metodisk gode studier er den beste kilden til informasjon om effekt av implementeringstiltak. The Cochrane Effective Practice and Organisation of Care Group (EPOC er en viktig kilde for slike oversikter. De systematiske oversiktene som er utarbeidet på dette feltet viser at passive dissemineringstiltak har begrenset effekt, mens mer aktive tiltak kan ha liten til moderat effekt. Det er ofte betydelig variasjon i effekt på tvers av studiene. Det er derfor viktig å få bedre kunnskap om hvilke faktorer som kan forklare slike forskjeller i effekt.Vi gir eksempler på norske implementeringsstudier, og refererer bidrag fra forskere ved Kunnskapssenteret. Implementeringsforskningen kan, hvis den lykkes, sikre pasientene bedre behandling.Flottorp S, Aakhus E. Implementation research: science for improving practice.

    The present study was to assess the reduction of right ventricular pacing (RVP) by pacemaker algorithms of Managed Ventricular Pacing (MVP) and Search AV+ (SAV+) interval over a period of 12 months. A total of 385 patients indicated for a dual-chamber pacemaker (DC-PM) were enrolled in the prospective, randomized COMPARE study at 29 centres in China between June 2009 and April 2011. Patients implanted with DC-PMs were randomized in a 1 : 1 ratio to the MVP group or the SAV+ group. The percentage of VP (%VP) was obtained from the device diagnostic data at 1-, 6-, and 12-month follow-ups and was expressed as the median %VP over all beats in patients with sinus node dysfunction (SND) and atrioventricular block (AVB) excluding persistent third-degree AVB. Of 385 enrolled patients, 253 had SND and 72 had AVB. The %VP in the MVP group was significantly lower than that in the SAV+ group at 1-, 6-, and 12-month follow-ups, respectively. At 12-month follow-up, the median %VP in SND patients was 0.20% in the MVP group and 1.4% in the SAV+ group (P sustainable %VP reduction has potential implications in reducing the development of heart failure and/or atrial arrhythmia morbidity.

    AV-1451 is an imaging agent labeled with the positron-emitting radiolabel Fluorine-18. 18F-AV-1451 binds paired helical filament tau (PHF-tau), a pathology related to Alzheimer's disease. In our study of AV-1451 uptake in the brains of cognitively normal subjects, we noted a case of a meningioma with visually significant uptake of AV-1451. We initiated the present retrospective study to further examine cases of meningioma that underwent AV-1451 imaging. We searched the patient records of 650 patients who had undergone AV-1451 at our institution for the keyword "meningioma" to identify potential cases. PET/CT and MRI results were visually reviewed and semi-quantitative analysis of PET was performed. A paired student's t test was run between background and tumor standard uptake values. Fisher's exact test was used to examine the association between AV-1451 uptake and presence of calcifications on CT. We identified 12 cases of meningioma, 58% (7/12) of which demonstrated uptake greater than background using both visual analysis and tumor-to-normal cortex ratios (T/N + 1.90 ± 0.83). The paired student's t test revealed no statistically significant difference between background and tumor standard uptake values (p = 0.09); however, cases with a T/N ratio greater than one showed statistically higher uptake in tumor tissue (p = 0.01). A significant association was noted between AV-1451 uptake and presence of calcifications (p = 0.01). AV-1451 PET imaging should be reviewed concurrently with anatomic imaging to prevent misleading interpretations of PHF-tau distribution due to meningiomas.

    The literature suggests that a history of depression is associated with an increased risk of developing Alzheimer's disease (AD). The aim of this study was to examine brain amyloid accumulation in patients with lifetime major depression using {sup 18}F-florbetapir (AV-45/Amyvid) PET imaging in comparison with that in nondepressed subjects. The study groups comprised 25 depressed patients and 11 comparison subjects who did not meet the diagnostic criteria for AD or amnestic mild cognitive impairment. Vascular risk factors, homocysteine and apolipoprotein E (ApoE) genotype were also examined. The standard uptake value ratio (SUVR) of each volume of interest was analysed using whole the cerebellum as the reference region. Patients with a lifetime history of major depression had higher {sup 18}F-florbetapir SUVRs in the precuneus (1.06 ± 0.08 vs. 1.00 ± 0.06, p = 0.045) and parietal region (1.05 ± 0.08 vs. 0.98 ± 0.07, p = 0.038) than the comparison subjects. Voxel-wise analysis revealed a significantly increased SUVR in depressed patients in the frontal, parietal, temporal and occipital areas (p < 0.01). There were no significant associations between global {sup 18}F-florbetapir SUVRs and prior depression episodes, age at onset of depression, or time since onset of first depression. Increased {sup 18}F-florbetapir binding values were found in patients with late-life major depression relative to comparison subjects in specific brain regions, despite no differences in age, sex, education, Mini Mental Status Examination score, vascular risk factor score, homocysteine and ApoE ε4 genotype between the two groups. A longitudinal follow-up study with a large sample size would be worthwhile. (orig.)

    The literature suggests that a history of depression is associated with an increased risk of developing Alzheimer's disease (AD). The aim of this study was to examine brain amyloid accumulation in patients with lifetime major depression using 18 F-florbetapir (AV-45/Amyvid) PET imaging in comparison with that in nondepressed subjects. The study groups comprised 25 depressed patients and 11 comparison subjects who did not meet the diagnostic criteria for AD or amnestic mild cognitive impairment. Vascular risk factors, homocysteine and apolipoprotein E (ApoE) genotype were also examined. The standard uptake value ratio (SUVR) of each volume of interest was analysed using whole the cerebellum as the reference region. Patients with a lifetime history of major depression had higher 18 F-florbetapir SUVRs in the precuneus (1.06 ± 0.08 vs. 1.00 ± 0.06, p = 0.045) and parietal region (1.05 ± 0.08 vs. 0.98 ± 0.07, p = 0.038) than the comparison subjects. Voxel-wise analysis revealed a significantly increased SUVR in depressed patients in the frontal, parietal, temporal and occipital areas (p 18 F-florbetapir SUVRs and prior depression episodes, age at onset of depression, or time since onset of first depression.

  19. AV dissociation, an inevitable response.

    Science.gov (United States)

    Wang, Kyuhyun; Benditt, David G

    2011-07-01

    The independent activation of the atria and ventricles, AV dissociation, is a common phenomenon that occurs during a wide variety of electrophysiologic circumstances. The clinical significance of AV dissociation is often misunderstood. This article examines the basis and clinical implications of AV dissociation. AV dissociation is often an obligatory, secondary phenomenon, and should not be construed as the primary disorder; it may be due to either the AV conduction system being completely blocked (3° AV block) or the P wave and the QRS complex being generated from separate sources (usually, the AV junction or ventricle) but occurring close together during the physiologic refractory period of each other. The latter may happen in junctional or ventricular arrhythmias including escape or accelerated rhythm, tachycardia, or premature beats. The crucial clinical point is not the AV dissociation itself, but that an underlying triggering primary disorder is present and should be identified. ©2011, Wiley Periodicals, Inc.

  2. Nursing identity and patient-centredness in scholarly health services research: a computational text analysis of PubMed abstracts 1986-2013.

    The most important and contested element of nursing identity may be the patient-centredness of nursing, though this concept is not well-treated in the nursing identity literature. More conceptually-based mapping of nursing identity constructs are needed to help nurses shape their identity. The field of computational text analytics offers new opportunities to scrutinise how growing disciplines such as health services research construct nursing identity. This paper maps the conceptual content of scholarly health services research in PubMed as it relates to the patient-centeredness of nursing. Computational text analytics software was used to analyse all health services abstracts in the database PubMed since 1986. Abstracts were treated as indicative of the content of health services research. The database PubMed was searched for all research papers using the term "service" or "services" in the abstract or keywords for the period 01/01/1986 to 30/06/2013. A total of 234,926 abstracts were obtained. Leximancer software was used in 1) mapping of 4,144,458 instances of 107 concepts; 2) analysis of 106 paired concept co-occurrences for the nursing concept; and 3) sentiment analysis of the nursing concept versus patient, family and community concepts, and clinical concepts. Nursing is constructed within quality assurance or service implementation or workforce development concepts. It is relatively disconnected from patient, family or community care concepts. For those who agree that patient-centredness should be a part of nursing identity in practice, this study suggests that there is a need for development of health services research into both the nature of the caring construct in nursing identity and its expression in practice. More fundamentally, the study raises questions about whether health services research cultures even value the politically popular idea of nurses as patient-centred caregivers and whether they should.

    To develop algorithms for calculating the Rheumatic Diseases Comorbidity Index (RDCI), Charlson-Deyo Index (CDI) and Functional Comorbidity Index (FCI) from the Medical Dictionary for Regulatory Activities (MedDRA), and to assess how these MedDRA-derived indices predict clinical outcomes, utility and health resource utilization (HRU). Two independent researchers linked the preferred terms of the MedDRA classification into the conditions included in the RDCI, the CDI and the FCI. Next, using data from the Norwegian Register-DMARD study (a register of patients with inflammatory joint diseases treated with DMARDs), the explanatory value of these indices was studied in models adjusted for age, gender and DAS28. Model fit statistics were compared in generalized estimating equation (prediction of outcome over time) models using as outcomes: modified HAQ, HAQ, physical and mental component summary of SF-36, SF6D and non-RA related HRU. Among 4126 patients with RA [72% female, mean (s.d.) age 56 (14) years], median (interquartile range) of RDCI at baseline was 0.0 (1.0) [range 0-6], CDI 0.0 (0.0) [0-7] and FCI 0.0 (1.0) [0-6]. All the comorbidity indices were associated with each outcome, and differences in their performance were moderate. The RDCI and FCI performed better on clinical outcomes: modified HAQ and HAQ, hospitalization, physical and mental component summary, and SF6D. Any non-RA related HRU was best predicted by RDCI followed by CDI. An algorithm is now available to compute three commonly used comorbidity indices from MedDRA classification. Indices performed comparably well in predicting a variety of outcomes, with the CDI performing slightly worse when predicting outcomes reflecting functioning and health. © The Author 2017.

  11. A Heart too Drunk to Drive; AV Block following Acute Alcohol Intoxication.

    Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people. By screening PubMed, Google Scholar, Scopus and JSTOR, fifteen cases were found of which eight were sufficiently documented for full analysis. Blood alcohol levels ranged from 90 to 958 mg/dl (19 to 205 mM). Second and third degree AV block was observed most (6/8) albeit that in two of these patients a vagal stimulus led to deterioration from first into higher order AV block. In all cases, patients reverted to normal sinus rhythm upon becoming sober again. Mildly lowered body temperature (35.9 ± 0.5°C) was observed but can be excluded as a major cause of conduction blockade. We hypothesize that ethanol induced partial inhibition of calcium and potentially also sodium currents in conductive tissue structures may be one of the mechanisms of conduction slowing and block that may become exaggerated upon increased vagal tone. An impairment of gap junction function cannot be excluded as a contributing factor. In conclusion, cases of documented alcohol induced AV block are very rare but events can occur at relatively low serum alcohol levels which should prompt to awareness of this phenomenon in alcohol intoxicated patients.

  12. Hva med de gjenstridige dokumentene? Fagreferentrollen i spesialsamlinger

    Directory of Open Access Journals (Sweden)

    Solveig Greve

    2010-07-01

    Full Text Available Spesialsamlinger er samlinger av ”gjenstridige dokumenter”, dvs. dokumenter som er sjeldne, unika eller upubliserte og derfor ofte er fysisk bundet til eierinstitusjonen. Det er typisk at slike samlinger mangler moderne standarder for metadata og felles nasjonale katalogiseringsverktøy. Eierinstitusjonene har et kulturansvar for bevaring og tilgjengeliggjøring av disse dokumentene overfor en bredere allmennhet enn et fagbiblioteks ”primærbrukere”. Fagreferentens oppgaver vil være preget av dette. Bevaring, sikring og produksjon av digitale fulltekstdokumenter er sentralt. Det er også typisk for slike samlinger at en har en betydelig backlog. Det vil være fagreferentens oppgave å løfte fram ukjent kildemateriale, gjennom digitaliseringsprosjekter og forskning. Fagreferentens viktigste oppgaver vil da være mer rettet mot samlingspleie og formidling av egne samlinger og mindre fokus på andre institusjoners samlinger. Slik vil også undervisningen av studentene bli preget av arkivpresntasjon av innhold og forelesninger om teoretiske og praktiske forhold knyttet til å arbeide med spesielle materialtyper og mindre til utvikling av vanlig informasjonskompetanse. Denne situasjonen vil forandre seg hvis/når institusjonene blir enige om utvekslingsformater og mengden av digitale fulltekstdokumenter øker. Utfordringene for spesialsamlinger vil også være fagreferentenes utfordringer; I en stadig mer elektronisk verden, kan arbeidet med de fysiske samlingene lett bli marginalisert, selv om nettopp den tekniske utviklingen kunne løse mange problemer for de gjenstridige dokumentene. Men slik prioritering krever store ressurser, høy kompetanse, engasjement og politisk gjennomslagskraft. Kostnadene er høye, og konkurrerer budsjettmessig med galopperende elektroniske utgifter for hele biblioteket. Spesialsamlingenes fagreferenter kan bli en minoritetsstemme i bibliotekenes moderniseringsprosess, til skade for bibliotekenes totale faglige

Elever møter ofte flere tekster om samme tema – multiple tekster – og vi trenger økt kunnskap om hvordan de leser slike tekster. Elevene leste fire ulike tekster om en sykkelulykke. Tekstene presenterte informasjon som var delvis sammenfallende på tvers av alle tekstene, og delvis motstridende informasjon som innebar at enkelte tekster ga ulike beskrivelser av hendelsesforløpet. Vi testet elevenes ordavkodingsferdigheter, fikk dem til å fylle ut et spørreskjema om lesevaner og vi innhentet elevenes resultater på Nasjonal leseprøve. Etter lesing ba vi elevene gi en oppsummering av sykkelulykken. Elevene gjenga relativt mer sammenfallende informasjon enn motstridende informasjon. Gode resultater på Nasjonal leseprøve ser ut til å ha en sammenheng med elevenes ferdigheter i å konstruere en sammenhengende forståelse av de fire tekstene. Elever som oppga å lese mye på Internett hadde imidlertid fått med mindre av informasjonen som var felles for de fire tekstene i sine oppsummeringer. Vi fant også en negativ sammenheng mellom fritidslesing på Internett og resultatene fra Nasjonal leseprøve. Samlet sett indikerer resultatene at når elevene skal skape sammenheng mellom flere delvis motstridende tekster, så blir sammenfallende informasjon vektlagt mer enn motstridende informasjon. Dessuten ser det ut til at de elevene som bruker mest fritid til å lese på Internett, sliter mer med å sammenfatte innholdet i de fire tekstene enn de andre elevene.

  3. How to reliably deliver narrow individual-patient error bars for optimization of pacemaker AV or VV delay using a "pick-the-highest" strategy with haemodynamic measurements.

    Science.gov (United States)

    Francis, Darrel P

    2013-03-10

    Intuitive and easily-described, "pick-the-highest" is often recommended for quantitative optimization of AV and especially VV delay settings of biventricular pacemakers (BVP; cardiac resynchronization therapy, CRT). But reliable selection of the optimum setting is challenged by beat-to-beat physiological variation, which "pick-the-highest" combats by averaging multiple heartbeats. Optimization is not optimization unless the optimum is identified confidently. This document shows how to calculate how many heartbeats must be averaged to optimize reliably by pick-the-highest. Any reader, by conducting a few measurements, can calculate for locally-available methods (i) biological scatter between replicate measurements, and (ii) curvature of the biological response. With these, for any clinically-desired precision of optimization, the necessary number of heartbeats can be calculated. To achieve 95% confidence of getting within ±∆x of the true optimum, the number of heartbeats needed is 2(scatter/curvature)(2)/∆x(4) per setting. Applying published scatter/curvature values (which readers should re-evaluate locally) indicates that optimizing AV, even coarsely with a 40ms-wide band of precision, requires many thousand beats. For VV delay, the number approaches a million. Moreover, identifying the optimum twice as precisely requires 30-fold more beats. "Pick the highest" is quick to say but slow to do. We must not expect staff to do the impossible; nor criticise them for not doing so. Nor should we assume recommendations and published protocols are well-designed. Reliable AV or VV optimization, using "pick-the-highest" on commonly-recommended manual measurements, is unrealistic. Improving time-efficiency of the optimization process to become clinically realistic may need a curve-fitting strategy instead, with all acquired data marshalled conjointly.

På bakgrunn av omfattende internasjonal forskning innen feltet ‘Vurdering for læring’ (VfL er det i denne studien utviklet teoridrevne hypoteser som testes ved å analysere et datasett fra to videregående skoler. Hypotesene er at elevene oppfatter lærers tilbakemelding som mer nyttig hvis den 1 retter seg mot målet med opplæringen, 2 gir elevene informasjon via en forklaring eller instruks om hvordan de skal komme nærmere målet og 3 at lærer legger til rette for bruk av tilbakemeldingen.

SEM er brukt fordi metoden egner seg til å undersøke sammenhenger i komplekse datasett. Funn er at elevene oppfatter at hvis lærer forklarer hvordan de kan forbedre seg, er dette positivt statistisk assosiert med opplevd nytte. Et mer overraskende funn er at lærerens tilrettelegging for bruk av tilbakemeldinger ikke er signifikant assosiert med opplevd nytte. Resultatene blir diskutert i artikkelen.

  9. Reduction of the applied load by prioritizing hot water production; Reducering av anslutningseffekten med hjaelp av VV-prioritering

    Energy Technology Data Exchange (ETDEWEB)

    Selinder, Patrik [ZW Energiteknik, Nykoeping (Sweden)

    2005-11-01

    The energy used in Swedish district heating networks is primarily used for heating purposes in buildings, whereas the energy used for heating the domestic hot water is a minor part - about 10 to 20 % - of the total energy used in district heating systems. However, as the involved heat capacity is concerned, both heating of hot water and heating of buildings are very often of comparable sizes. Although effect of simultaneity of hot water consumption reduces the total hot water heating capacity in the built environment, the behaviour pattern of the customers is such that the hot water use results in high hot water loads for a given building at certain hours of a day. The preparation of domestic hot water therefore makes large demands on the heating capacity of the district heating net in relation to the ability of repayment due to the energy consumption. However, a building exhibits in general a good possibility for decreasing the total heat load by involving its thermal mass and therefore borrowing under limited time a part of its house heating capacity for hot water heating purposes. The thermal mass of the building ensures that this 'capacity-borrowing' is not experienced as a decrease in comfort. The goal of this project was to develop and to test a control algorithm acting on the control system of a customer substation with the purpose of temporarily reduce the heat delivery when high hot water demands occur. This algorithm has then been tested in a residential building in Goeteborg, Sweden. The control principle was applied on a Swedish customer substation with two heat exchangers connected in parallel for both radiator heating and instantaneous domestic hot water preparation. The basic idea was to reduce the opening angle of the radiator valve when a larger demand of hot water occurs (indicated by opening of the hot water control valve). A control algorithm based on certain physical parameters calculates in this case the closing angle of the radiator valve. Different control algorithms have been tested and a final algorithm was evaluated under a longer period. It was shown that both flow rates as well as heating capacities decreased considerably compared to the normal case when the priority-algorithm was activated. In the final analysis, however, it was shown that the control algorithm could be further improved for taking care of some special operational conditions. The algorithm can be quite simply applied in Swedish substations by exchanging the existing control system by a programmable DUC combined with suitable software. This could be done more or less at the same costs as normal control devices. No other changes of the substations are needed.

  10. Recovery of acidified forest land when harvesting varying fractions of biomass; Aaterhaemtning av foersurad skogsmark med olika uttag av biomassa

    Energy Technology Data Exchange (ETDEWEB)

    Moldan, F.; Manngaard, B.; Westling, O.

    2001-08-01

    IVL, has described the effects of five scenarios of future forest management on recovery from acidification of soil and run off during a rotation. The study was conducted by use of the dynamic model MAGIC. The calculations were applied on a forest site in the southern part of Sweden with acidified soil and a productive spruce forest, which is common in the southwestern part of Sweden. The soil of the studied site was acidified several decades ago when the emissions of air pollutants in Europe, especially sulphur, increased according to the model calculations. At the same time a productive spruce forest was established, which also contributed to the acidification by cation uptake and ion exchange with H{sup +}. The reduction of the emissions of sulphur after 1980 enabled a recovery process, indicated by, for example, increased ANC and decreased concentrations of inorganic aluminium in soil water. But the recovery will not be complete and the achieved degree of recovery will be depending of the type of forest management according to the calculations. The model calculations show that the combination between deposition of air pollutants and growing forests have resulted in a yearly net loss of 36 meq/m{sup 2} of base cations (resulting in soil acidification) from the soil during the period 1850 to 2015. The future yearly net loss of base cations, with lower deposition, could reach 15 meq /m{sup 2} with whole tree harvesting (including needles) during one rotation between 2015 and 2085. The amount of branches, tops and needles left after clear cutting and thinning contribute to the variation between 4 and 15 meq/m{sup 2} in average yearly net loss of base cations from the soil depending of the amount of biomass removed by harvest. The model calculations of the historic and future development of acidification in this study involve several sources of uncertainty. The long time span, assumed removal of biomass by harvest and compensatory fertilisation contributes to the uncertainties. In spite of that the method has proved to be a valuable tool to assess the need of additional reductions of emissions of air pollutants and also the impact of different forest management methods on future soil and water acidification. But the method need to be further developed and applied to assess the role of acidifying air pollutants in relation to forest management for recovery in acidified areas.

    Congenital cardiac and neurodevelopmental deficits have been recently linked to the mediator complex subunit 13-like protein MED13L, a subunit of the CDK8-associated mediator complex that functions in transcriptional regulation through DNA-binding transcription factors and RNA polymerase II. Heterozygous MED13L variants cause transposition of the great arteries and intellectual disability (ID). Here, we report eight patients with predominantly novel MED13L variants who lack such complex congenital heart malformations. Rather, they depict a syndromic form of ID characterized by facial dysmorphism, ID, speech impairment, motor developmental delay with muscular hypotonia and behavioral difficulties. We thereby define a novel syndrome and significantly broaden the clinical spectrum associated with MED13L variants. A prominent feature of the MED13L neurocognitive presentation is profound language impairment, often in combination with articulatory deficits.

For det første må det tas stilling til den prinsipielle stillingen til voldgiftsregulerte krav ved domstolene. For det andre reiser objektiv kumulasjon særlige tolkningsspørsmål ved tolkningen av voldgiftsavtalen. Oppgavens kjerne er dermed å redegjøre ...

  1. Hva er det med Irma?

    Directory of Open Access Journals (Sweden)

    Anne Beate Reinertsen

    2016-10-01

    Full Text Available Abstract: This article is about formative quality assessment in a posthuman or newmaterial perspective; embodied knowledges.  Theory and method are written together in immanence to envision complexity.  The aim and scope of the article is to follow the flow of events Irma produces opening up for affirmative poetical critique praxis. Quality is forwarded as an intensity and force in a moment only.  The moment is therefore the only structure of the text, as moving quality. The intention and inner logic of the text is therefore designed to work against fixed definitions and conceptualizations of what quality and quality assessment is.  This way I hope to show what posthuman and newmaterial approaches can contribute with to build cultures of innovation in which quality is assessed and produces again and again. They put differences to work and open up for creating moments of educational justice. Sammendrag: Artikkelen handler om kvalitetsvurdering i et nymaterielt perspektiv: Kroppslig kunnskap og viten. Teori og metode skrives sammen i immanent samtidighet for å gi et bilde på kompleksitet. Både hensikt og mål med artikkelen er å følge den flyten som Irma som hendelse eller event produserer, for å åpne opp potensialitet for en bekreftende eller affirmativ poetiserende kritikkpraksis og en ny forståelse av- og vurdering for kvalitet. Kvalitet skrives fram som en hendelse, intensitet eller kraft i et øyeblikk. Øyeblikket er derfor tekstens eneste og bærende struktur, som kvalitet i bevegelse. Tekstens indre logikk har slik til hensikt å motvirke forsøk på å skape definerte, faste eller bestemte oppfatninger av hva kvalitet er og hvordan kvalitet kan vurderes. På denne måten håper jeg å vise hva nymaterielle perspektiver kan gjøre for å bygge kulturer for innovasjon hvor kvalitet vurderes og produseres igjen og igjen. De setter forskjellighet i bevegelse og åpner opp for å skape rettferdige utdanningsøyeblikk.

    2012-01-01

    Materiale og metode: Undersøkelsen omfatter 87 personer med utviklingshemning som tidligere har bodd på en sentralinstitusjon. Datainnsamling skjedde ved at omsorgspersoner fylte ut ABDQ.  Resultater: Det var 24 % i utvalget som hadde nedgang i adaptiv atferd. Fortolkning: ABDQ er et hjelpemiddel til å avdekke nedgang i adaptiv atferd. Det er viktig at svikt avdekkes tidligst mulig og videreformidles til helsepersonell for utredning, diagnostisering, relevant behandling og tilrettelagte helse- og omsorgstjenester. Mange personer med utviklingshemning mestrer ikke å informere om egen helsetilstand og er avhengig av at omsorgspersonalet kan avdekke sykdom og lidelser så tidlig som mulig i sykdomsforløpet.

    First aid (FA) services are provisioned on-site as a preventive measure at most public events. In Flanders, Belgium, the Belgian Red Cross-Flanders (BRCF) is the major provider of these FA services with volunteers being deployed at approximately 10,000 public events annually. The BRCF has systematically registered information on the patients being treated in FA posts at major events and mass gatherings during the last 10 years. This information has been collected in a web-based client server system called "MedTRIS" (Medical Triage and Registration Informatics System). MedTRIS contains data on more than 200,000 patients at 335 mass events. This report describes the MedTRIS architecture, the data collected, and how the system operates in the field. This database consolidates different types of information with regards to FA interventions in a standardized way for a variety of public events. MedTRIS allows close monitoring in "real time" of the situation at mass gatherings and immediate intervention, when necessary; allows more accurate prediction of resources needed; allows to validate conceptual and predictive models for medical resources at (mass) public events; and can contribute to the definition of a standardized minimum data set (MDS) for mass-gathering health research and evaluation.

    Directory of Open Access Journals (Sweden)

    Ann Merete Otterstad

    2015-09-01

    Full Text Available This article challenges observation as a method in early childhood, justified as a mapping tool for creating knowledge about children. Observation as data material is about writing down already known categorisation about children and their development. Categories and categorisation make a foundation for correspondence and coherence   - connections that might create generalising knowledge about children in early years. The article is about a research project conducted in a child-centre over a two-year period. We had an on-going conversation with the personnel around theories about ‘child development’. In the article we experiment with observation based on posthuman/newmaterial theories. Our specific interests are to explore the complexities around observation by asking; why observations, what do we expect through observation, and what might observation as datamaterial be/become? We are inspired by the Norwegian film “Kitchen Stories” (Salmer fra Kjøkkenet, Hamer, 2003 both as affect/provocation and desire (Koro-Ljungberg & MacLure, 2013. We search for affective bending and messiness (Lather, 2007; Law, 2004 to disturb and challenge observation as dominating paradigm in the field of early years, to break some patterns around the positioning of data material. Artikkelen utfordrer observasjon i barnehagen ut fra at metoden brukes som verktøy for å kartlegge og danne grunnlaget for utvikling av kunnskap om barn.  Observasjon som datamateriale innebærer iakttagelser og nedtegnelser av allerede gitte kategoriseringer om barn og barns utvikling.  Kategorier og kategorisering legger grunnlag for mønster som har i seg ideer om korrespondanse og koherens – sammenhenger som kan bidra til generaliserende kunnskap om barna i barnehagen. Omrisset av artikkelen dreies rundt et forskningsarbeid gjort i en barnehage over en toårs-periode, der vi sammen med de ansatte diskuterer teorier om barn og barns ’utvikling’. Vi bruker posthumane

    Full Text Available I denna studie analyserar vi hur erfarna förskollärare i rollen som handledare introducerar förskollärarstudenter i professionen. Studien genomförs mot bakgrund av ett delvis nytt uppdrag som förskolan fått under senare år, som bland annat yttrar sig i att förskolan nu är en del av utbildningssystemet. Med utgångspunkt i det teoretiska begreppet argumentationstraditioner och genom att analysera metaforiken i deltagarnas resonerande, studeras hur erfarna och blivande förskollärare navigerar spänningar centrala för professionen. Deltagarnas betoning av vissa argumentationstraditioner och användningen av viss metaforik diskuteras i termer av vad de implicerar för utvecklingen av de barn som deltar i en förskoleverksamhet som formas av dessa.

    2017-10-01

    Full Text Available Artikkelen undersøker hva slags forståelse lærerutdannere og lærerstudenter har av estetiske arbeidsformer i undervisningen i lærerutdanningene. Studien er en kvalitativ intervjuundersøkelse blant lærerutdannere og lærerstudenter ved en norsk lærerutdanningsinstitusjon. I lys av danningsteoretisk og didaktisk teori, finner studien at lærerutdannere og lærerstudenters forståelse av estetiske arbeidsformer i undervisningen er kjennetegnet av «frihet» som fravær av tvang og fasit i arbeid med lærestoffet, «fantasi» som bruk av forestillingsevnen slik at kunnskapen blir personlig, og «utfoldelse» som sosialisering inn i et fellesskap gjennom tilbakemeldinger på egen atferd. Til sammen kan informantenes forståelse av de tre aspektene sies å fremheve viktigheten av å utvikle de lærendes autonomi. Artikkelen gir et bidrag til undervisningspraksis i lærerutdanningene, gjennom å gi eksempler på hva estetiske arbeidsformer kan være i en slik sammenheng. Avslutningsvis drøftes funnene opp mot samtidige politiske begrunnelser for bruk av estetiske arbeidsformer i utdanningene.

  7. Brachial artery aneurysms following brachio-cephalic AV fistula ligation.

    2014-01-01

    Peripheral artery aneurysms proximal to a long-standing arteriovenous (AV) fistula can be a serious complication. It is important to be aware of this and manage it appropriately. Vascular access nurses input all data regarding patients undergoing dialysis access procedures into a securely held database prospectively. This was retrospectively reviewed to identify cases of brachial artery aneurysms over the last 3 years. In Morriston Hospital, around 200 forearm and arm AV fistulas are performed annually for vascular access in renal dialysis patients. Of these, approximately 15 (7.5%) are ligated. Three patients who had developed brachial artery aneurysms following AV fistula ligation were identified. All 3 patients had developed brachial artery aneurysms following ligation of a long-standing brachio-cephalic AV fistula. Two patients presented with pain and a pulsatile mass in the arm, and one presented with pins and needles and discoloration of fingertips. Two were managed with resection of the aneurysm and reconstruction with a reversed long saphenous vein interposition graft, the third simply required ligation of a feeding arterial branch. True aneurysm formation proximal to an AV fistula that has been ligated is a rare complication. There are several reasons for why these aneurysms develop in such patients, the most plausible one being the increase in blood flow and resistance following ligation of the AV fistula. Of note, all the patients in this study were on immunosuppressive therapy following successful renal transplantation. Vigilance by the vascular access team and nephrologists is paramount to identify those patients who may warrant further evaluation and investigation by the vascular surgeon.

  9. Biomass based energy combines with motor fuel production; Biobraenslebaserade energikombinat med tillverkning av drivmedel

    Energy Technology Data Exchange (ETDEWEB)

    Goldschmidt, Barbara

    2005-01-01

    In the report the state of development of production processes for various motor fuels, such as FT diesel, methanol , DME and ethanol, from biomass is reviewed. Biomass and black liquor gasification processes as well as processes for ethanol production from lignocellulosic biomass are discussed. The processes are complicated and still not very well tried in their whole context. The gas cleaning steps, which are necessary to reach acceptable catalyst lifetimes in the motor fuel production processes based on gasification, have been tested in the oil industry and to some extent in coal gasification plants, but not with syngas from biomass or black liquor gasification. For black liquor gasification particularly, also material selection and material lifetime issues remain to be solved. For ethanol production from lignocellulosic biomass process development is needed, to increase the yield in the pre-treatment, hydrolysis and fermentation steps. The energy yields of the processes are dependent on the degree of complexity of the processes, as well as on the integration and balancing of energy demanding steps and steps with energy surplus. This is especially valid for the processes based on gasification, due to high temperatures in the gasifier and some of the catalytic steps, but also for the ethanol process, which benefit from optimal steam integration in the evaporation and distillation steps. Also steam integration with cogeneration plants, or for black liquor gasification with pulp mills, improves the overall energy balance. In addition, the energy yield when motor fuels are produced by gasification is dependent on the usage of the off-gas. The efficiency is improved when the off-gas is burned in a boiler or gas turbine, than when it is flared. In the report examples are given of processes with and without integration.

    1995-05-01

    The report gives a description of the five Swedish communities that already have nuclear facilities, in order to find the potential for selecting any of these for a future Swedish nuclear waste repository. Only existing, available information has been collected for this report, with the aim to find the interest and need for more detailed localization studies. The following subjects are treated: General data like area, population, industry etc. Communications (road, rail and airports). Existing facilities. Geology. Hydrology. Experiences from rock constructions. Land use, planning, natural reserves etc. Local technical conditions for transport and construction. The following conclusions are drawn: Oskarshamn, Nykoeping and Oesthammar have good geologic potentials and should be candidates for more extensive geologic studies. The geologic potential of Varberg is less well known, and geologic mapping and geophysical measurements are needed. Kaevlinge does not have geologic or technical potentials on par with the other communities, and can be disregarded for further studies. 64 refs, 18 figs.

    2010-10-15

    The purpose of the research project presented in this report was to find ways to return a lower temperature from the generator of the chillers in a supply/return connection. The initial target is 40 deg C. Ideally, the absorption chiller and possible ulterior uses of the remaining heat in the heat carrier (the water flowing through the generator) should be as close as possible to a pure heat load. The hot-water driven absorption chillers used today to produce cooling in DH networks are exclusively so-called single-effect (Sweden) chillers with water and lithium bromide as working pair. This study aims at raising as much as possible the upper bounds on the absorption chiller capacity that may be connected to a DH network, by lowering the temperature at the outlet. To this end, several approaches have been used: - A search for alternative designs of the absorption chiller, focusing on commercially available and tested technology, both those yielding a large temperature decrease over the generator and those that may be operated at lower temperatures than the conventional solutions; - An examination of the impact of further uses of the remaining heat on temperature in the return line. larger. Smaller units are considered only if they can be used to illustrate a principle. As a complement to this investigation, a few other issues have been treated: - What temperature levels should a system actually be designed for? - The LAVA method to calculate the impact of supply and return temperatures in the DH network on the economics of power production is presented; - Interesting technical solutions using desiccant-aided evaporative cooling are shortly described; - The modern developments in the field of working pairs (refrigerant and absorbent) are reviewed. Assumptions made here are that there is a significant demand for cooling, and that the demand is large enough to justify operating the cogeneration plant at a load level exceeding its lowest acceptable part load rather than an auxiliary heat-only boiler. A number of types of absorption cooling machines and a few system designs that yield lower temperatures at the outlet from the generator are proposed in this report. However, reconsidering the system temperatures may lead to reduced generator temperatures also for a standard SE absorption chiller and consequently to lower temperatures at the outlet from the generator. The best answer is, of course, the SE/DL type of absorption chiller. To make best use of a heat supply system cascading through two SE-machines in series, one should also cascade the cold side: either adopting a 6/18 deg C chilled water circuit or splitting the cold output into two circuits at different temperatures, but spanning the same 6/18 deg C interval. Desiccant-aided evaporative cooling has a potential to provide precisely what is being asked for: peak load cooling and low regeneration temperatures which would allow for also low temperatures in the return line of the DH network. In another part of the investigation, the benefits of using the heat remaining in the heat carrier after passage through the generator have been demonstrated. Any use of heat downstream from the generator leads to lower return temperatures. There are not, however, many reasonable uses of heat, except hot tap water. Nevertheless, the most efficient system seems to be obtained when energy stores are used. Storing hot water and distributing it yields the lowest temperatures. Storing energy as chilled water does not improve the return temperature in the DH network, but then its purpose was only to reduce the capacity of the chiller needed. One should in this case consider also storing hot water or try to make some use of the remaining heat in the heat carrier. In the third part of the investigation, working pairs of refrigerant and absorbent were reviewed. There is not yet any serious competitor to the traditional pairs, ammonia-water and water-lithium bromide. Most proposals have failed at some point of the development work. In the case of improvements to the water-lithium bromide system, the viscosity of the absorbent was too high

  15. Drying of bio fuel utilizing waste heat; Torkning av biobraenslen med spillvaerme

    Many industries today have large sources of low grade heat (waste heat), however this energy is mainly lost with effluents to air and water. The aim of this study has been to investigate the technical and economical aspects of utilizing this low grade heat to dry biofuel. The project has been mainly focused towards the forest industry since they have both large amounts of biofuel and waste heat available. Drying of biofuel could generate added revenue (or reduced purchase costs) and through that also create larger incentives for further energy saving modifications to the main process. Due to the higher moisture content together with the risk of frozen bark in the winter time, additional fuels (such as oil) to combust bark in the existing boiler. This is mainly the case when mechanical dewatering is not available. Drying of bark results in an added energy value, which makes it possible to combust the bark without additional fuel. The primary energy demand, in the form of electricity and optional additional heating at load peaks, is low when waste heat is used for the drying process. In this way it is possible to increase the biofuel potential, since the primary energy input to the drying process is essentially lower then the increased energy value of the fuel. Drying also decreases the biological degradation of the fuel. Taking all the above into consideration, waste heat drying could result in a 25 % increase of the biofuel potential in the forest industry in Sweden, without additional cutting of wood. A survey has been done to state which commercial technologies are available for biofuel drying with waste heat. An inquiry was sent out to a number of suppliers and included a few different cases. Relations for approximating investment cost as well as electric power demand were created based on the answers from the inquiry. These relations have then been used in the economical evaluations made for a number of cases representing both sawmills and pulp and paper mills. In these evaluations the costs for transport has also been taken into account. A survey of available waste heat sources at saw mills and pulp mills has been done. The energy content in theses sources were compared with the energy needed for the drying process to see if the sources were large enough. The study has resulted in the following conclusions: There are large sources of waste heat available that could be used for drying purposes at pulp and paper mills. At sawmills the sources of waste heat are lower in comparison with the energy needed for drying. At pulp and paper mills it should be profitable with an investment in a biofuel dryer utilizing waste heat. The most profitable alternative is to use flue gases from the recovery boiler as drying gas (presuming that no flue gas condenser is installed). The profitability of a drying process at a sawmill is also good. Bed drying seems to be the most suitable technology both from a technical and commercial point of view.

    This report estimates the effects of regulated trade among the Scandinavian countries in a socio-economic perspective. Model simulations indicate that free trade is advantageous to Norway. In the short term foreign trade serves first of all to even out the effects of a variable supply of water to the hydroelectric power plants. In the long term trade with the other countries is connected primarily with peak load export/low load import. Free trade is advantageous to Denmark and Finland as well. In the short term free trade is essential for achieving a reasonably effective competition in the Swedish market. Simulations indicate, however, that in the long term Sweden may profit from trade regulations. 19 refs., 41 figs., 7 tabs.

    Full Text Available Norwegian legislation concerning restraint measures in the care and treatment to people with intellectual disability (ID has been established since 1999. This study examined the social workers’ explanations for the increased number of people with ID being legally restrained since 1999. This article discussed both staff and the supervisors perspectives of the increase. Although an increasingly number of people with ID are treated by restraint measures, respondents (n = 206 report that care services has evolved in a positive direction. The strong increase is explained by a higher ethical awareness and changes in legal rules along the way. When asked about the future development, most respondents expect a continuing growth in the number of people with ID treated with the use of restraint measures.

    The objective of this study was to evaluate the amyloid burden, as assessed by {sup 18}F-florbetapir (AV-45/Amyvid) positron emission tomography PET, in patients with major depressive disorder (MDD) with different subtypes of mild cognitive impairment (MCI) and the relationship between amyloid burden and cognition in MDD patients. The study included 55 MDD patients without dementia and 21 healthy control subjects (HCs) who were assessed using a comprehensive cognitive test battery and {sup 18}F-florbetapir PET imaging. The standardized uptake value ratios (SUVR) in eight cortical regions using the whole cerebellum as reference region were determined and voxel-wise comparisons between the HC and MDD groups were performed. Vascular risk factors, serum homocysteine level and the apolipoprotein E (ApoE) genotype were also determined. Among the 55 MDD patients, 22 (40.0 %) had MCI, 12 (21.8 %) non-amnestic MCI (naMCI) and 10 (18.2 %) amnestic MCI (aMCI). The MDD patients with aMCI had the highest relative {sup 18}F-florbetapir uptake in all cortical regions, and a significant difference in relative {sup 18}F-florbetapir uptake was found in the parietal region as compared with that in naMCI subjects (P < 0.05) and HCs (P < 0.01). Voxel-wise analyses revealed significantly increased relative {sup 18}F-florbetapir uptake in the MDD patients with aMCI and naMCI in the frontal, parietal, temporal and occipital areas (P < 0.005). The global cortical SUVR was significantly negatively correlated with MMSE score (r = -0.342, P = 0.010) and memory function (r = -0.328, P = 0.015). The negative correlation between the global SUVR and memory in the MDD patients remained significant in multiple regression analyses that included age, educational level, ApoE genotype, and depression severity (β = -3.607, t = -2.874, P = 0.006).

  14. The role of AV and VV optimization for CRT

    Directory of Open Access Journals (Sweden)

    William W. Brabham, M.D.

    2013-06-01

    Full Text Available Cardiac resynchronization therapy is an effective therapy for patients with left ventricular systolic dysfunction and a ventricular conduction delay; however, approximately 30% of patients do not experience significant clinical improvement with this treatment. Modern devices allow individualized programming of the AV delay and VV offset, which offer the possibility of improving clinical response rates with optimized programming. AV and VV delay optimization techniques have included echocardiography, device-based algorithms, and several other novel noninvasive techniques. While an acute improvement in hemodynamic function has been clearly demonstrated with optimized device settings, long-term clinical benefit is limited. In the majority of cases, an empiric AV delay with simultaneous biventricular or left ventricular pacing is adequate. The value of optimization of these intervals in “non-responders” still requires further investigation.

    Full Text Available  SAMMENDRAGSvalbard er spesielt godt egnet til å vurdere påliteligheten av selvrapportert alkoholkonsum. På grunn av detlave prisnivået for alkohol er ulovlig import eller hjemmeproduksjon av alkohol ukjent på Svalbard. Dessutener samfunnet lite og oversiktlig, slik at det er praktisk mulig å undersøke hele befolkningen. I den aktuellestudien registrerte vi alt salg av alkohol til fastboende nordmenn på Svalbard i oktober og november 1988. Isamme tidsperiode ble alle nordmenn 18 år eller eldre invitert til å ta del i en helseundersøkelse der det inngikkspørsmål om alkoholbruk. Vi fant at selvrapportert alkoholkonsum utgjorde rundt 40% av salgsvolumet.På grunn av de spesielle forhold når det gjelder alkoholomsetning på Svalbard er det grunn til å anta atestimatet i denne studien er mer pålitelig sammenlignet med tilsvarende studier fra andre områder.Høyer G, Nilssen O, Brenn T, Schirmer H. The reliability of self-reported alcohol consumption.The Svalbard study 1988-89. Nor J Epidemiol 1996; 6 (1: 109-113.ENGLISH SUMMARYThe Norwegian island of Spitzbergen, Svalbard offers a unique setting for validation studies on self-reportedalcohol consumption. No counterfeit production or illegal import exists, thus making a complete registrationof all sources of alcohol possible. In this study we recorded sales from all agencies selling alcohol onSvalbard over a two month period in 1988. During the same period all adults living permanently on Svalbardwere invited to take part in a health screening. As part of the screening a self-administered questionnaire onalcohol consumption was introduced to the participants. We found that the self-reported volume accounted forapproximately 40 percent of the sales volume. Because of the unique situation applying to Svalbard, theestimate made in this study is believed to be more reliable compared to other studies using sales volume tovalidate self-reports.

    Under de senaste decennierna parallellt med klimatdiskussionen har det vuxit fram ett stort intresse för höghastighetståg och en förbättrad infrastruktur i Sverige. I delar av Europa men speciellt i Kina och Japan har utvecklingen av höghastighetståg fått ett enormt lyft. Ett problem vid höjda tåghastigheter är att broarna vid en kombination av låg massa och låg egenfrekvens riskerar att orsaka resonans och höga accelerationsnivåer vid passage.

    Full Text Available Artikkelen tar utgangspunkt i tre observasjoner av en gutt på fire år som bruker iPad på fritiden. Den søker å synliggjøre de strategiene dette barnet velger for å skaffe seg tilgang til ulike medietekster, hvordan han leser og tolker dem, og den undersøker eventuelle spor av kritisk refleksjon hos barnet over disse tekstene. Teoretisk sett hviler den på en forståelse av mediekompetanse som en parallell prosess til utvikling av lese- og skrivekyndighet (literacy, og medieopplevelsene omtales som viktige møter med tekst. Artikkelen undersøker hvordan å lese medietekster kan legge et grunnlag for å utvikle en utvidet tekstkompetanse eller mediekompetanse. Konklusjonen legger vekt på motivasjon og lekenhet som barns primære inngang til medietekstene og som et grunnlag for å utvikle mediekompetanse (media literacy. The article is based on three observations of a four-year-old boy who uses the iPad in his spare time. It demonstrates the strategies that this boy applies to gain access to various media texts, and how he reads and interprets them. It also seeks to examine traces of critical reflection that he may demonstrate in relation to these texts. Theoretically, it rests on an understanding of media literacy as a parallel process to the development of literacy, and it seeks to demonstrate how reading media texts can create an important starting point for the development of media literacy. The Kindergarten practitioner’s role and opportunities to develop children's media literacy within a kindergarten context is a focus towards the end of the article. In conclusion, I argue that motivation and playfulness are important approaches to media texts and create an important foundation for the development of media literacy

    To study the usefulness of 18 F-AV-1451 PET in patients with corticobasal syndrome (CBS). We recruited 8 patients with CBS, 17 controls, 31 patients with Alzheimer disease (AD), and 11 patients with progressive supranuclear palsy (PSP) from the Swedish BioFINDER study. All patients underwent clinical assessment, 18 F-AV-1451 PET, MRI, and quantification of β-amyloid pathology. A subset of participants also underwent 18 F-FDG-PET. In the 8 patients with CBS, 6 had imaging findings compatible with the corticobasal degeneration pathology and 2 with typical AD pathology. In the 6 patients with CBS without typical AD pathology, there were substantial retentions of 18 F-AV-1451 in the motor cortex, corticospinal tract, and basal ganglia contralateral to the most affected body side. These patients could be clearly distinguished from patients with AD dementia or PSP using 18 F-AV-1451. However, cortical atrophy was more widespread than the cortical retention of 18 F-AV1451 in these CBS cases, and cortical AV-1451 uptake did not correlate with cortical thickness or glucose hypometabolism. These results are in sharp contrast to AD dementia, where 18 F-AV-1451 retention was more widespread than cortical atrophy, and correlated well with cortical thickness and hypometabolism. Patients with CBS without typical AD pathology exhibited AV-1451 retention in the motor cortex, corticospinal tract, and basal ganglia contralateral to the affected body side, clearly different from controls and patients with AD dementia or PSP. However, cortical atrophy measured with MRI and decreased 18 F-fluorodeoxyglucose uptake were more widespread than 18 F-AV-1451 uptake and probably represent earlier, yet less specific, markers of CBS. This study provides Class III evidence that 18 F-AV-1451 PET distinguishes between CBS and AD or PSP. Copyright © 2017 The Author(s).

  20. Medisinsk profesjonalitet: Mestring av legeyrket

    Directory of Open Access Journals (Sweden)

    Per Stensland

    2014-06-01

    Full Text Available When the doctor uses theoretical knowledge, clinical skills, and clinical communication in a way that takes care of the patient, this may be called professionalism. The article aims to show that medical professionalism, in all specialities, may be understood and taught through the two complex concepts “leadership” and “patient-centred medicine”. The article is built on a literature-search with a selection of articles based on the authors’ experience in the field. Leadership is an implicit part of clinical work. The concept gives a perspective on the solution of clinical problems and gives a frame for understanding interaction in consultations and in other professional relations. The doctor personal leadership actualizes professional tutoring as part of the education. Models for patient-centred medicine have emphasized the doctor’s attitudes, skills, and use of linguistic means, and they have deepened the doctor’s understanding for exploring the patient’s problem. Newer models also discuss the doctor’s actions and therapeutic actions and underscorethe leader-role in series of decision-making moments in the consultation. Patient-centred clinical work should be based on an understanding of the doctor as an active co-editor and co-producer of the patient’s illness narrative. Professionalism, interpreted as patient-centred leadership, gives a direction for medical education that may help doctors to cope with their work.

    2013-12-01

    Full Text Available Background Informatics tools may help support hypertension management.Objective To design, implement and evaluate a web-based system for patient anti-hypertensive medication self-titration.Methods Study stages included: six focus groups (50 patients to identify barriers/facilitators to patient medication self-titration, software design informed by qualitative analysis of focus group responses and a six-month single-arm pilot study (20 patients to assess implementation feasibility.Results Focus groups emphasised patient need to feel confident that their own primary care providers were directly involved and approved of the titration protocol. Physicians required 3.3 ± 2.8 minutes/patient to create individualised six-step medication pathways for once-monthly blood pressure evaluations. Pilot participants (mean age of 51.5 ± 11 years, 45% women, mean baseline blood pressure 139/84 ± 12.2/7.5 mmHg had five medication increases, two non-adherence self-reports, 52months not requiring medication changes, 24 skipped months and 17 months with no evaluations due to technical issues. Four pilot patients dropped out before study completion. From baseline to study completion, blood pressure decreased among the 16 patients remaining in the study (8.0/4.7 mmHg, p = 0.03 for both systolic and diastolic pressures.Conclusions Lessons learned included the benefit of qualitative patient analysis prior to system development and the feasibility of physicians designing individual treatment pathways. Any potential clinical benefits were offset by technical problems, the tendency for patients to skip their monthly self-evaluations and drop outs. To be more widely adopted such systems must effectively generalise to a wider range of patients and be integrated into clinical workflow.

    Full Text Available Hensikten med studiet var å belyse hvordan videodokumentasjon av praktiske handlinger i sykepleie kunne brukes som evalueringordning av studenter. Artikkelen tar utgangspunkt i et forskningsprosjekt for utprøving av nye lærings og evalueringsformer i bachelorutdanningen i sykepleie, der 13 studentgrupper gjennomførte sin praktiske eksamen ved innlevering av video av 16 utvalgte øvelser. Tradisjonell praktisk eksamen i samme studentkull ble gjennomført for 10 studentgrupper. Prosjektet er en kvalitativ kasusstudie og analyse er gjort etter inspirasjon av Giorgi‘s empiriske fenomenologi. Diskusjonen tar utgangspunkt i Vygotsky‘s sosiokulturelle syn på læring og Dewey‘s prinsipp om at all læring er basert på erfaring. Funnene er presentert i følgende deler: Første del omhandler videodokumentasjon og refleksjon. De to neste delene viser funn i forhold til mesterlæring og situert læring på vei mot forståelse av hva sykepleie er. Deretter er teknisk utfordringer belyst, og til slutt en drøfting av forhold ved oppøving av praktiske sykepleieferdigheter. Konklusjonen her er at video egner seg til å dokumentere sykepleiehandlinger. Dette har størst verdi for læring og refleksjon, i mindre grad som eksamensform.

    Accumulation of cortical and subcortical tau pathology is the primary pathological substrate for progressive supranuclear palsy (PSP). 18 F-AV-1451, a radiotracer that binds to the pathological tau protein, may be helpful for in vivo visualization and quantitation of tau pathology in PSP. The objectives of this study were to investigate cortical and subcortical 18 F-AV-1451 binding patterns in patients with PSP. We recruited 14 PSP patients and compared their cortical and subcortical binding patterns in 18 F-AV-1451 positron emission tomography (PET) studies with those of 15 Parkinson's disease (PD) patients and 15 healthy controls. In both the PD and PSP groups, subcortical 18 F-AV-1451 binding did not correlate with the severity of motor dysfunctions, and cortical binding did not differ between the controls and each patient group. However, the PSP patients showed greater 18 F-AV-1451 binding in the putamen, globus pallidus, subthalamic nucleus, and dentate nucleus when compared with the controls, whereas the PD patients showed lower 18 F-AV-1451 binding in the substantia nigra than controls. The PSP and PD patients showed distinct subcortical 18 F-AV-1451 binding patterns reflecting subcortical tau pathology in PSP and reduced nigral neuromelanin in PD. However, there was no correlation with the severity of motor dysfunction, no cortical regions with increased binding in PSP patients, and variable degrees of subcortical binding even in the controls. Therefore, the 18 F-AV-1451 PET may be less than ideal for assessing tau pathology in PSP. Further studies will be required to validate the clinical correlation and to understand the clinical utility of 18 F-AV-1451 PET for PSP patients. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

  9. Forholdet mellom stat og kommune i styring av norsk utdanningspolitikk 1970 - 2008

    Directory of Open Access Journals (Sweden)

    Øystein Engeland

    2009-06-01

    Full Text Available Denne artikkelen er skrevet ut fra en antakelse om at norsk utdanningsforvaltning etter 1990 illustrerer forsøk på å styrke den statlige forvaltning innen et desentralisert system. Ikke minst er dette tydelig ved at nasjonal styring av utdanning særlig etter århundreskiftet har økt på bekostning av det lokale selvstyret. I forhold til maktfordelingen mellom staten og kommunene er vi nå nærmest tilbake til situasjonen før den politiske desentraliseringsbølgen startet mot slutten av 1970-tallet. Det nasjonale nivået er i ferd med å etablere et styringsgrep på skolesiden som er så omfattende at det mangler sidestykke i moderne tid. Det nye er at dette skjer innen et system hvor inntektssystemet (1986 gir kommunene ansvar for undervisningen, og hvor statens mulighet til å bruke økonomiske styringsmidler er redusert.

    Development of AV-block is a frequent complication associated with transcatheter aortic valve implantation (TAVI). To date little is known about the predictive value of the HV-interval prior to TAVI with respect to the risk of AV-block development. HV-interval was determined in 25 consecutive elderly patients with severe aortic valve stenosis (AS) before and immediately after TAVI. All patients subsequently underwent TAVI and 8 of these 25 patients (32%) developed complete AV-block during the TAVI procedure requiring permanent pacemaker implantation. Six of these 8 patients (75%) had marked HV prolongation (>54 ms). Pre-procedural HV-interval was significantly prolonged in the subgroup developing complete AV-block (62.1 ms±13.0 vs 49.2 ms±12.9; P=0.029). Prolongation of the HV-interval above 54 ms was associated with a higher rate of complete AV-block (sensitivity 75.0%, specificity 77.8%, P=0.01). HV-interval was prolonged in approximately one third of our elderly patients with aortic valve stenosis and associated with a high rate of complete AV-block following TAVI. HV-interval is easily obtained during TAVI screening procedures, thus facilitating identification of patients at risk for complete AV-block due to TAVI and consequently enabling bespoke risk management.

    2015-01-01

    Junctional ectopic tachycardia (JET) is a postoperative complication with a mortality rate of up to 14% after surgery for congenital heart disease. This study evaluated the risk factors of JET and explored the association of postoperative temporary third degree atrioventricular (AV) block and the occurrence of JET. Data were collected retrospectively from 1158 patients who underwent surgery for congenital heart disease. The overall incidence of JET was 2.8%. Temporary third degree AV block occurred in 1.6% of cases. Permanent third degree AV block requiring pacemaker implantation occurred in 1% of cases. In all, 56% of patients with JET had temporary AV block (P AV block (P = 0.56). temporary third degree AV block did not suffer from JET. A correlation between temporary third degree AV block and postoperative JET could be observed. The risk factors identified for JET include younger age groups at the time of surgery, longer aortic cross clamping time and surgical procedures in proximity to the AV node.

    Full Text Available I denne artikkelen setter vi søkelyset på førstelektorløpet som en vei til førstekvalifisering med utgangspunkt i lærerutdanningen. I henhold til nasjonale retningslinjer skal opprykk til førstelektor være en karrierevei for ansatte «med omfattende forsknings- og utviklingsarbeid rettet mot profesjons- og yrkesfelt, og omfattende pedagogisk utviklingsarbeid». Førstelektorveien er dermed et alternativ til doktorgraden for personer med omfattende virksomhet rettet mot profesjons- og yrkesfelt.Selv om det i nyere tid har vært en økende oppmerksomhet rettet mot førstelektorkvalifiseringen, er det fortsatt lite forskning knyttet til feltet også innenfor lærerutdanningen, som sammen med helsefag sannsynligvis er de to profesjonsutdanningene som har benyttet seg mest av denne kvalifiseringsmuligheten.Nasjonal statistikk viser at antall førstelektorer er økende, spesielt innenfor de profesjonsutdanningene som tradisjonelt har vært knyttet til de statlige høgskolene.

    The [ 18 F]AV-1451 positron emission tomography ligand allows the in vivo assessment of tau proteins in the brain. It shows strong binding in Alzheimer's dementia, but little is known about how it performs in progressive supranuclear palsy, a primary 4R tauopathy. The objectives of this study were to determine whether [ 18 F]AV-1451 uptake can be observed in progressive supranuclear palsy and to characterize the regional distribution when compared with controls and Alzheimer's dementia. [ 18 F]AV-1451 positron emission tomography was performed in 10 patients with probable progressive supranuclear palsy. These patients were age- and gender-matched to 50 controls and 10 Alzheimer's dementia patients who had undergone identical [ 18 F]AV-1451 imaging. Regional comparisons of [ 18 F]AV-1451 uptake were performed across the whole brain using region-of-interest and voxel-level analyses, and correlations between regional [ 18 F]AV-1451 and the progressive supranuclear palsy rating scale were assessed. An elevated [ 18 F]AV-1451 signal was observed in progressive supranuclear palsy when compared with controls in the pallidum, midbrain, dentate nucleus of the cerebellum, thalamus, caudate nucleus, and frontal regions. Signal in the cerebellar dentate and pallidum were also greater in progressive supranuclear palsy when compared with Alzheimer's dementia. Conversely, the [ 18 F]AV-1451 signal across the cortex was higher in Alzheimer's dementia when compared with progressive supranuclear palsy. The [ 18 F]AV-1451 signal in a number of regions correlated with the progressive supranuclear palsy rating scale. Progressive supranuclear palsy is associated with an elevated [ 18 F]AV-1451 signal in a characteristic and distinct regional pattern that correlates with disease severity and differs from the patterns observed in Alzheimer's dementia. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

    A 91-year-old woman received a dual-chamber pacemaker for sick sinus syndrome and intermittently abnormal atrioventricular (AV) conduction. The pacemaker was set in DDI mode with a 350-ms AV delay to preserve intrinsic ventricular activity. She complained of palpitation during AV sequential pacing. The electrocardiogram showed a 2:1 AV rhythm from 1:1 ventriculoatrial (VA) conduction during ventricular pacing in DDI mode with a long AV interval. After reprogramming of the pacemaker in DDD mode with a 250-ms AV interval and additional 100-ms prolongation of the AV interval by the ventricular intrinsic preference function, VA conduction disappeared and the patient's symptom were alleviated without increasing unnecessary right ventricular pacing. ©2011, The Authors.

    Cardio neuroablation (CNA) is a lesser-known technique for management of patients with excessive vagal activation on the basis of radiofrequency catheter ablation (RFCA) of the areas related to the three main autonomic ganglia around the heart. We investigated the effectiveness of selective and/or stepwise RFCA of these areas via right atrium (RA) and/or left atrium (LA) in the patients with recurrent syncope due to excessive vagal activity. Twenty-two patients presenting symptomatic functional bradyarrhythmias, neurally mediated reflex syncope (NMS), symptomatic atrioventricular (AV) block, and symptomatic sinus node dysfunction (SND; number = 8, 7, 7, respectively) were enrolled. The three main paracardiac ganglia were targeted via RA and LA in the patients with NMS and SND. The procedure was performed via RA in the patients with AV block, followed by RFCA of all ganglia via LA, if AV conduction disorder persists. The sites showing fragmented potentials were identified by electrical mapping and verified by high-frequency stimulation and ablated until atrial electrical potential was completely eliminated (AV block. Despite the increased heart rate, the resolution of AV block after the RFCA could not be achieved in one patient who had partial resolution with atropine infusion on admission. CNA may be an alternative and safe strategy to reduce NMS episodes, and to treat functional AV block and symptomatic SND, especially in young patients. © 2015 Wiley Periodicals, Inc.

    During co-combustion of biofuel and Refused Derived Fuels (RDF) there is a risk that the future level of allowed dioxin emissions could be exceeded. Dioxin can be reduced by primary combustion measures or secondary measures such as active carbon. The active carbon method is used in plants with high levels of dioxin and has a relatively high operation cost. To operate active carbon there is also need for fabric filter in the plant. The aim of the project was to investigate the potential of inhibition of dioxin formation during co-combustion of wood and recovered fuels by additives containing sulphur and nitrogen. The study was mainly conducted in pilot-scale but verifying measurements was also done in a full-scale boiler. Costs and synergy effects of the additives have been investigated. In the pilot-scale experiments a 5 kW fluidised bed reactor was used and the full-scale experiment was done at Johannes heat plant (bubbling fluidised bed). The additives ammonium sulphate, sulphur dioxide and ammonia were added in gas or liquid state. The additives containing sulphur had an inhibiting effect on the formation of dioxin in the study. The largest effect gave SO{sub 2} added with the primary air. It reduced the formation of dioxins and chloro benzenes by 58% and 73% respectively. The addition of ammonium sulphate reduced 41% of the dioxin formation and 77% of the chloro benzene formation. Nitrogen additives did not inhibit the formation of dioxin. The dioxin content in the full-scale, when co-combusting up to 25% recovered fuel, was very low (0,02-0,03 ng/Nm{sup 3}). A higher content of dioxin was measured when ammonia sulphate was added. This was probably due to the higher amount of recovered fuel (double amount) during the period when the ammonium sulphate was added. That changed the conditions of dioxin formation between the samples. The addition of sulphur was lower in the full-scale experiment compared to the pilot-scale experiments. In the full-scale experiments a sulphur:chlorine ratio of 1:1 was added, which gave about 25 ppm SO{sub 2} in the flue gas. This can be compared with the pilot-scale experiments with a sulphur:chlorine ratio of 4-6:1 that resulted in 200-300 ppm SO{sub 2}. These high amounts of sulphur in the flue-gas demand some sort of sulphur cleaning if it would be used in a full-scale plant. Based on the uncertainness in the experiments and the small amount of measurements no conclusions can been drawn concerning recommended amount additive to reduce the formation of dioxin. The conclusion is instead that the study should be complemented with further experiments. The addition of SO{sub 2} (or elementary sulphur in full-scale) is (individually) the most cost effective additive. The cost for sulphur is about 1,7 SEK/MWh, which can be compared to ammonia sulphate that cost about 2,3 SEK/MWh. Ammonia and urea are the most expensive additives and did not give any inhibited effect of the dioxin formation. The costs for the additives cannot be compared directly. The additives are often already used in the plant or, if a decision is made to use additive, there are other positive effects than dioxin inhibition. A complete cost-benefit valuation should therefore be carried out before making the choice of additive.

    In the coming years, a large number of landfills will be closed as a result of new environmental legislation and more stringent requirements. The availability of suitable material for covering and sealing is limited, especially in large urban areas. Sludge and ash are potentially useful materials for this purpose. The project 'Covering landfill with sludge and ash' was carried out from 2003 to 2005. The project involved the establishment and monitoring of different test areas having liners (sealing layers) of sewage sludge and fly ash. The experience gained from this project has also been used in the development of guidelines for using fly-ash-stabilised sewage sludge (FSS) as a liner. In the current project, two test areas have been monitored for a three-year period. Investigations have focused on the permeability of the materials, chemical properties of both runoff water and percolating water, resistance to decomposition, subsidence/compaction, strength, etc. The project was financed by Vaermeforsk, Svensk Vatten Utveckling and the two participating facilities (Tekniska Verken in Linkoeping and SRV Aatervinning in Huddinge). The study was carried out by Geo Innova in collaboration with both facilities, and the Department for Water and Environmental Studies at Linkoeping University. The project involved sampling and analysis of water, pore gas and solid material. In the field, subsidence and water levels have been measured. The results have been compared with the guideline levels for surface water, between different sampling and measurement locations (above and below the liner, with and without drainage, steep and flat areas, etc), and at different times. The results show that the FSS liner is impermeable. The requirement for landfills for non-hazardous waste is satisfied; in some cases the permeability is on a par with the requirement for hazardous waste landfills. Some decomposition of the material occurs, as indicated by the detection of methane and carbon dioxide in the pore gas. It was not possible to quantify the magnitude of the decomposition, although results of measurements of organic content in the material suggest that decomposition is limited. Effects of decomposition on the function of the liner have not been observed. The runoff water from the liner surface contains high concentrations of metals, nutrients and organic carbon compared to the Swedish EPA's threshold values for surface water. This water corresponds to that which will eventually reach a watercourse, lake, etc, possibly after treatment. The concentrations have decreased during the follow-up period. In summary, the liner composed of the FSS mixture is judged to function well as regards permeability and durability. The investigated test areas are only 3-4 years old, and further follow-up studies of permeability, durability, and properties of the runoff water should provide valuable information. Concentrations in the runoff water have not stabilized. It would be of particular interest to investigate if the permeability can meet the requirements for hazardous waste landfills and to verify the trend towards lower concentrations in the runoff water

    Full Text Available I utdanningsvitenskapelig litteratur er ulike former for ”literacy” et vedvarende fokus både teoretisk og empirisk. I engelskspråklig naturfagdidaktisk litteratur brukes betegnelsen ”scientific literacy”. Jeg skisserer i denne artikkelen et planleggingsverktøy for undervisning som bygger på en eksplisitt teoretisk modell for deltakelse gjennom språk. Modellen er bindeledd mellom et generalisert kompetansebegrep og planlegging av undervisning ved at den knytter sammen de didaktiske spørsmålene hva, hvem, hvordan og hvorfor med en modell for funksjonell deltakelse. Modellen er spesielt relevant for et allmenndannende ”naturfag for alle”, men favner også et naturfag som fokuserer på utdanning av framtidas naturvitere. Artikkelen retter seg mot naturfag i skolen, men modellen bør kunne anvendes også i andre skolefag. Modellen peker mot et situert og transformativt kompetansebegrep.Nøkkelord: naturfag , kompetanse , diskurs , deltakelse, undervisning og læringAbstractVarious forms of literacy have long been the focus of educational discourses, not the least in science education where the term “scientific literacy” has been an enduring concern for decades. In this article I describe a tool for designing teaching based on a theoretical perspective on participation through language. The model connects a general conception of competence with the planning of teaching. To do so it drowe on the didactical questions of “what, who, how and why”. The model is particularly relevant in a “science for all” perspective but also for the educating of future science specialists. Although school science is the primary focus in this article, the model should be applicable to other school subjects as well. The model opens for a situated and transformative notion of competence.Keywords: scientific literacy, discourse, participation, teaching and learning

    Tuberous sclerosis is a neurologic disease affecting various organs with a triade: sebaceum adenoma, mental retardation and seizures. This report presents a case of a patient with tuberous sclerosis and third degree A-V block with complete invasive and non-invasive evaluation. The patient had sincope and complete A-V block with QRS complexes showing right bundle branch block morphology. The echocardiogram showed dilated cardiomyopathy with diffuse left ventricular dysfunction and had normal coronary arteriography. The eletrophysiologic evaluation showed complete infra-hisian A-V block and QRS with left bundle branch block pattern with normal sinus nodal and A-V nodal function. It was not possible to induce ventricular tachtyarrhythmias up to two extrastimuli. Histologic study showed normal myocardium under light and electronic microscopy. After permanent VVI pacemaker implant, the patient in follow-up for 16 years. This case seems to be the first in the international medical literature of tuberous sclerosis with complete heart block.

  1. First-degree AV block-an entirely benign finding or a potentially curable cause of cardiac disease?

    Science.gov (United States)

    Holmqvist, Fredrik; Daubert, James P

    2013-05-01

    First-degree atrioventricular (AV) block is a delay within the AV conduction system and is defined as a prolongation of the PR interval beyond the upper limit of what is considered normal (generally 0.20 s). Up until recently, first-degree AV block was considered an entirely benign condition. In fact, some complain that it is a misnomer since there is only delay and no actual block in the AV conduction system (usually within the AV node). However, it has long been acknowledged that extreme forms of first-degree AV block (typically a PR interval exceeding 0.30 s) can cause symptoms due to inadequate timing of atrial and ventricular contractions, similar to the so-called pacemaker syndrome. Consequently, the current guidelines state that permanent pacemaker implantation is reasonable for first-degree AV block with symptoms similar to those of pacemaker syndrome or with hemodynamic compromise, but also stresses that there is little evidence to suggest that pacemakers improve survival in patients with isolated first-degree AV block. Recent reports suggest that it may be time to revisit the impact of first-degree AV block. Also, several findings in post hoc analyses of randomized device trials give important insights in possible treatment options. The present review aims to provide an update on the current knowledge concerning the impact of first-degree AV block and also to address the issue of pacing in patients with this condition. ©2013, Wiley Periodicals, Inc.

    Full Text Available Å forske med kunsten innebærer ikke bare valget av visse metoder for bruk i forskningsprosessen, men også om å ha til disposisjon spesifikke måter å tenke om metode. I denne artikkelen vil jeg synliggjøre en tenkemåte fundert i arbeidet med en skjønnlitterær lesesirkel for lærerstudenter, og min egen erfaring som improvisasjonsmusiker. Jazzens begrep om jam blir løftet frem som omdreiningspunkt for tenkemåten, som ellers har sitt teoretiske utspring i den franske filosofen Gilles Deleuze’s forestilling om bliven. Denne vitale forestillingen innebærer at verden produseres kontinuerlig, noe forskeren også bidrar til. Koblingen mellom jam, litteratur og Deleuze synliggjør dessuten en måte å tenke om metode på som understreker at det å forske med kunsten ikke bare betyr å forske på kunsten, men at kunsten på ulike måter kan virke inn på selve forskningen og slik også bidra til å affirmere verden i sin bliven. I tillegg til å tilby en måte å tenke om metode for den som skal forske med kunsten, er hensikten med artikkelen å gjøre forskeren bevisst sin egen tenkning om metode, noe som er viktig siden denne skaper mulighetsbetingelser for metodevalg og -bruk.

    2012-11-15

    The genesis of complex ventricular rhythms during atrial tachyarrhythmias in humans is not fully understood. To clarify the dynamics of atrioventricular (AV) conduction in response to a regular high-rate atrial activation, 29 episodes of spontaneous or pacing-induced atrial flutter (AFL), covering a wide range of atrial rates (cycle lengths from 145 to 270 ms), were analyzed in 10 patients. AV patterns were identified by applying firing sequence and surrogate data analysis to atrial and ventricular activation series, whereas modular simulation with a difference-equation AV node model was used to correlate the patterns with specific nodal properties. AV node response at high atrial rate was characterized by 1) AV patterns of decreasing conduction ratios at the shortening of atrial cycle length (from 236.3 ± 32.4 to 172.6 ± 17.8 ms) according to a Farey sequence ordering (conduction ratio from 0.34 ± 0.12 to 0.23 ± 0.06; P AV block patterns occurring during regular atrial tachyarrhythmias. The characterization of AV nodal function during different AFL forms constitutes an intermediate step toward the understanding of complex ventricular rhythms during atrial fibrillation.

    This study investigated binding of [ 18 F]AV-1451 to neuromelanin in the substantia nigra of patients with Parkinson's disease (PD) and progressive supranuclear palsy (PSP). [ 18 F]AV-1451 is a positron emission tomography radiotracer designed to bind pathological tau. A post-mortem study using [ 18 F]AV-1451 discovered off-target binding properties to neuromelanin in the substantia nigra. A subsequent clinical study reported a 30% decrease in [ 18 F]AV-1451 binding in the midbrain of PD patients. A total of 12 patients and 10 healthy age-matched controls were recruited. An anatomical MRI and a 90-min PET scan, using [ 18 F]AV-1451, were acquired from all participants. The standardized uptake value ratio (SUVR) from 60 to 90 min post-injection was calculated for the substantia nigra, using the cerebellar cortex as the reference region. The substantia nigra was delineated using automated region of interest software. An independent samples ANOVA and LSD post hoc testing were used to test for differences in [ 18 F]AV-1451 SUVR between groups. Substantia nigra SUVR from 60 to 90 min was significantly greater in HC compared to both PSP and PD groups. Although the PD group had the lowest SUVR, there was no significant difference in substantia nigra uptake between PD and PSP. [ 18 F]AV-1451 may be the first PET radiotracer capable of imaging neurodegeneration of the substantia nigra in parkinsonisms. Further testing must be done in PD and atypical parkinsonian disorders to support this off-target use of [ 18 F]AV-1451.

    Empiric programming of the atrio-ventricular (AV) delay is commonly performed during pacemaker implantation. Transmitral flow assessment by Doppler echocardiography can be used to find the optimal AV delay by Ritter's method, but this cannot easily be performed during pacemaker implantation. We sought to determine a non-invasive surrogate for this assessment. Since electrocardiographic P-wave duration estimates atrial activation time, we hypothesized this measurement may provide a more appropriate basis for programming AV intervals. A total of 19 patients were examined at the time of dual chamber pacemaker implantation, 13 (68%) being male with a mean age of 77. Each patient had the optimal AV interval determined by Ritter's method. The P-wave duration was measured independently on electrocardiograms using MUSE® Cardiology Information System (version 7.1.1). The relationship between P-wave duration and the optimal AV interval was analyzed. The P-wave duration and optimal AV delay were related by a correlation coefficient of 0.815 and a correction factor of 1.26. The mean BMI was 27. The presence of hypertension, atrial fibrillation, and valvular heart disease was 13 (68%), 3 (16%), and 2 (11%) respectively. Mean echocardiographic parameters included an ejection fraction of 58%, left atrial index of 32 ml/m(2), and diastolic dysfunction grade 1 (out of 4). In patients with dual chamber pacemakers in AV sequentially paced mode and normal EF, electrocardiographic P-wave duration correlates to the optimal AV delay by Ritter's method by a factor of 1.26.

    Objective To examine region and substrate-specific autoradiographic and in vitro binding patterns of PET tracer [F-18]-AV-1451 (previously known as T807), tailored to allow in vivo detection of paired helical filament tau-containing lesions, and to determine whether there is off-target binding to other amyloid/non-amyloid proteins. Methods We applied [F-18]-AV-1451 phosphor screen autoradiography, [F-18]-AV-1451 nuclear emulsion autoradiography and [H-3]-AV-1451 in vitro binding assays to the study of postmortem samples from patients with a definite pathological diagnosis of Alzheimer’s disease, frontotemporal lobar degeneration-tau, frontotemporal lobar degeneration-TDP-43, progressive supranuclear palsy, corticobasal degeneration, dementia with Lewy bodies, multiple system atrophy, cerebral amyloid angiopathy and elderly controls free of pathology. Results Our data suggest that AV-1451 strongly binds to tau lesions primarily made of paired helical filaments in Alzheimer’s brains e.g. intra and extraneuronal tangles and dystrophic neurites, but does not seem to bind to a significant extent to neuronal and glial inclusions mainly composed of straight tau filaments in non-Alzheimer tauopathy brains or to β-amyloid, α-synuclein or TDP-43-containing lesions. AV-1451 off-target binding to neuromelanin- and melanin-containing cells and, to a lesser extent, to brain hemorrhagic lesions was identified. Interpretation Our data suggest that AV-1451 holds promise as surrogate marker for the detection of brain tau pathology in the form of tangles and paired helical filament-tau-containing neurites in Alzheimer’s brains but also point to its relatively lower affinity for lesions primarily made of straight tau filaments in non-Alzheimer tauopathy cases and to the existence of some AV-1451 off-target binding. These findings provide important insights for interpreting in vivo patterns of [F-18]-AV-1451 retention. PMID:26344059

    In this study, we designed and tested a new algorithm, which we call the 'restricted parabola', to identify the optimum atrioventricular (AV) delay in patients with biventricular pacemakers. This algorithm automatically restricts the hemodynamic data used for curve fitting to the parabolic zone in order to avoid inadvertently selecting an AV optimum that is too long.We used R, a programming language and software environment for statistical computing, to create an algorithm which applies multiple different cut-offs to partition curve fitting of a dataset into a parabolic and a plateau region and then selects the best cut-off using a least squares method. In 82 patients, AV delay was adjusted and beat-to-beat systolic blood pressure (SBP) was measured non-invasively using our multiple-repetition protocol. The novel algorithm was compared to fitting a parabola across the whole dataset to identify how many patients had a plateau region, and whether a higher hemodynamic response was achieved with one method.In 9/82 patients, the restricted parabola algorithm detected that the pattern was not parabolic at longer AV delays. For these patients, the optimal AV delay predicted by the restricted parabola algorithm increased SBP by 1.36 mmHg above that predicted by the conventional parabolic algorithm (95% confidence interval: 0.65 to 2.07 mmHg, p-value = 0.002).AV optima selected using our novel restricted parabola algorithm give a greater improvement in acute hemodynamics than fitting a parabola across all tested AV delays. Such an algorithm may assist the development of automated methods for biventricular pacemaker optimisation.

    Device optimization is not routinely performed in patients who underwent cardiac resynchronization therapy (CRT) device implantation. Noninvasive optimization of CRT devices by measurement of cardiac output (CO) can be used as a simple method to assess ventricular systolic performance. The aim of this study was to assess whether optimization of atrioventricular (AV) and interventricular (VV) delay can improve hemodynamic response to CRT and whether this optimization should be performed for each patient individually. Twenty patients with advanced heart failure New York Heart Association (NYHA) class III/IV, left ventricular ejection fraction ≤ 35% and left bundle branch block (QRS ≥ 120 ms) in sinus rhythm were evaluated from 24 h to 48 h after implantation of a CRT device by means of impedance cardiography (ICG). CO was first measured at each patient's intrinsic rhythm. Patients then underwent adjustments of AV and VV delay from 80 ms to 140 ms and from -60 ms to +60 ms, respectively in 20 ms increment steps and CO at each setting was measured by ICG. Both AV and VV delays were programmed according to the greatest improvement in CO compared to intrinsic rhythm. There was a statistically signifi cant increase in CO measured at the intrinsic rhythm compared to different AV delay by mean of 21% (3.8 ± 1.0 vs. 4.6 ± 0.1 L/min, p AV/VV delays with left ventricle-preexcitation or simultaneous biventricular pacing caused additional increased CO from intrinsic rhythm by mean of 32.6% (3.8 ± 1.0 vs. 5.04 ± ± 1.0 L/min, p AV/VV setting delays also resulted in improved hemodynamic responses compared to VV factory setting delay. Both AV and VV delay optimization should be performed in clinical practice. Optimal AV delay improved outcome. However, combination of optimized AV/VV delays provided the best hemodynamic response. Optimized AV/VV delays with left ventricle-preexcitation or simultaneous biventricular pacing increased hemodynamic output compared to intrinsic

    In this report, integrated biofuel drying has been studied for two cases. One is the existing CHP plant at ENA Energi AB in Enkoeping and the other is a theoretical case. The thought plant is assumed to have a steam generating performance that is probable for a future CHP plant optimised for power production. The CHP plant at ENA Energi with its integrated bed drying system has been used as a model in this study. The plant has a grate fired boiler with the capacity to co-produce 24 MW electricity and 55 MW heat. It is designed to use biofuel with moisture content between 40 and 55 %. However, the boiler is able to manage even dryer fuels with the moisture content of about 35 % without complications. Since the boiler operates on part load during most of the season, there are free capacity which can be used for delivering heat to the drying system. The increased power production is a result of mainly two factors: Increased demand of heat as the dryer uses district heating and thus improved possibility to produce steam; and, The season of operation can be extended, since the point where the minimum load of the boiler occurs can be pushed forward as a result of increased demand of heat. For future CHP plants, an optimised plant has been used as a model. The steam data is assumed to be 170 bar and 540 deg C with reheating. For this plant, both on-site and offsite drying have been studied. The case study comprises a whole season of operation and the fuel is assumed to be dried from 50 to 10 %. The size of the optimised plant is as to fit the dimension of a main production unit in a district heating net equal to the tenth largest in Sweden. Heat delivery is assumed to be 896 GWh/year and the maximum heat delivery of district heating is 250 MW. The sizing of the boiler is made to maximise the production of electricity, and thus dependent of the drying strategy used. Flue gas condensation is assumed to be used as much as possible. It decreases the basis for power production, but is considered adequate since it contributes to an overall efficient use of biofuel. The case studies at ENA Energi show that integrated drying has the ability to improve production of electricity by 12 %. In the case studies where an optimised plant with integrated drying is studied, calculations show a possible improvement of production of electricity by 65 %. If storage of dried biofuel is applied, the production of electricity can be increased even more. For the optimised plant, the electrical efficiency based on lower heating value at delivery can be increased from 34 % to approximately 40% using integrated drying. Results from the study show that an optimised plant is able to pay 20 % more when buying dried biofuel compared to wet biofuel, based on the dry content. The rate between income from electricity and cost for fuel as SEK/MWh needs to exceed 2 to get profitability of an investment in an integrated drying system. Integrated drying is a powerful tool to improve the electrical efficiency at all kinds of power plants. Integrated drying is therefore of interest for ordinary power plants

    Energy production through co-combustion of biofuel and the dry fraction of household waste might be an alternative in the future for rural district areas since the present system for recovery has been criticized. So far the results from the co-combustion of briquettes made by energy grass, Reed Canary grass, in mixture with very well separated dry fraction of household waste shows that new developed commercial boiler technology, 100-1000 kW, have been well designed for good function, high efficiency and low emissions using ordinary cyclone flue gas cleaning. By consideration of the new EU incineration waste directive for co-combustion of biofuel and waste fractions the achieved emission levels from this trials in many cases seem to fulfill the directive including critical parameters such as CO and dioxins without highly advanced flue gas cleaning. Mixture of waste together with energy grass does not raise the emission levels of HCl compared to pure energy grass combustion. The importance of developing systems for well sorted dry fractions of household waste have been verified in the project. The quality insurance of the fuel is necessary to consider the new EU-directive. In this project studies of systems for sorting of dry waste have been compared. A system in which the sorting part can be identified and attained by information and premium awards shows obvious advantages compared with local central placed container systems for the dry waste.

    Good methods enabling quick determination of moisture in wood fuels are lacking. A standardized method generally used by the biofuel industry means drying samples in furnaces during at least 16 hours. The idea of this work has been to investigate if x-ray technique can offer a superior alternative for fast moisture determination. Analysis with x-ray has many advantages. The x-rays go completely through the whole test specimen. Large samples or many sequential samples can rapidly be measured. The penetration is extraordinary good; all parts of the tested mass will be analyzed. The measurement relies on the absorption of gamma photons in the tested mass. The x-ray absorption is carried out deep down in the atoms and therefore is independent of the materials equation of state as temperature, grain size or molecule binding. The disadvantages of the method are the general anxiety which can be for gamma rays, the relative high cost for equipment and the fact that an x-ray tube will wear with time and needs replacement. The method used here for moisture measurement is known as dual energy x-ray. The test sample is simultaneously exposed to transmission of two separate x-ray energies. The two energies are absorbed differently by the sample. The ratio of the absorption in the two respective energies is calculated and from that conclusions on the composition of the material can be drawn. The equipment used in this test is a standard medical apparatus adapted for the study of human body composition. When instead used for measurements of moisture in wood material the discrimination signal is about half of that achieved in the normal medical case. Despite that, the signal has been good enough for giving satisfactory accuracy in the moisture estimation. A little more than sixty approved results are presented in the report comprehending ten different fuel types. The results are grouped into three main categories depending on fuel type, wood fuels, peat fuels and salix including some of the mixed fuels. Provided that the main category is known the moisture content can be determined within one or two percent from the measurements. A complication is that the procedure requires that the fuel type be known. The method offers a relative measurement which means that it relies on calibration against known references. Different types of fuels therefore to some extent need different calibrations. This is basically due to the differences in carbon content which affects the result. With a further development of the method there are ways to overcome this difference in the total absorption resulting in a measurement more or less independent of the fuel type. As the content of carbon as well as of oxygen strongly affects the absorption, one would also in principle be able to calculate the heat content of the fuel. On top of that there is a correlation of the absorption to the mineral content, which opens a possibility to calculate the amount of ash in the material. To reveal these for biofuels highly interesting parameters a substantial effort of software development in the data treatment is required. A fine-tuning of the x-ray energies is also desirable to reach a higher signal ratio for the case moisture in wood, compared to what is possible with the medical equipment. These development steps are regarded fully feasible and are recommended to be taken in the coming work.

  9. Integration of heat treatment of wood with cogeneration production and district heating; Vaermebehandling av trae integrerad med kraftvaermeproduktion och fjaerrvaerme

    Heat treatment of wood changes the properties of wood so that the moisture uptake is reduced and the wood movements are reduced at variations in the ambient air humidity. The wood gets an increased resistance to rot and can therefore replace impregnated wood in certain applications. Heat treated wood is however not suitable for direct contact with soil. The strength is also reduced by heat treatment, so it is not recommended for supporting constructions. No additives whatsoever are used in the treatment, so the heat treated wood is very advantageous from an environmental point of view. The wood is dried completely at the heat treatment and heated to about 200 deg C. The question has hence been put, if it is advantageous to collocate a heat treatment plant with district heating or a power cogeneration plant. The aim of the study is to assess the value of such a collocation. Existing heat treatment plants are both few and small and the calculations have hence been made for how a large plant could be designed. A market study is included to assess the market for this type of plants. This shows that the present market for heat treated wood is very small. A full scale treatment plant of the type discussed in this study could probably not be built, since even single plants of this size would require a too large part of the market. The potential to replace impregnated wood is on the other hand very large. The cost for large scale heat treatment should be significantly lower than for impregnated wood and the cost for handling hazardous waste (which impregnated wood is classified as) is also removed. There should therefore be a potential for a future much larger volume of heat treated wood. The study shows that the energetic profit of collocation of a heat treatment plant for wood with district heating or power cogeneration plants is of lower importance. Maximally about 0.5 MSEK/year can be saved for a 25 000 m3/year plant. The initial drying of all sawn lumber has much more to gain from a collocation and this is yet very unusual today. The main conclusion of the study is that heat treatment of wood seems to be very interesting, but collocation with district heating or power cogeneration plants is not a decisive or even important factor. The author therefore believes the study answers the question of the value of collocation

    A project has been conducted of a large number of power and pulp plants in Sweden. Production managers and those responsible for water quality control were visited and interviewed. In addition, a research of cycle chemistry literature has been conducted to determine what has been done in other countries. The review of this literature shows that the Electric Power Research Institute in the USA and ESKOM in South Africa are in the forefront regarding QA/QC and have come a long way in water control management. A key requirement for successful plant cycle chemistry is corporate management support. The project makes it clear that cycle chemistry control was best at plants where production management was aware of the importance of high water quality. There is a real need for feed water technique and water quality education at all company levels. The objective should be that 'everyone should know the importance of right water quality'. Personnel without an education in chemistry often regard cycle chemistry as somewhat complicated. Better understanding and better working cycle chemistry control can be obtained by making the control easier and clearer for persons without training in chemistry. Extensive on-line instrumentation with well-designed systems for presenting the data, by-far, gives the best cycle chemistry control. It is important to have a holistic view when water treatment systems and on-line instrumentation are planned. It is not the amount of instruments or the number of chemistry personnel that is important. The important thing is to ensure that all functions needed fit together in the best way possible. Today, when cycle chemistry monitoring is heavily dependent on on-line instrumentation, the reliability of the instruments is crucial. Therefore, it is important to have well-established routines for maintenance, calibration and service. In order to decrease forced outages of plants due to poor cycle chemistry, the focus of chemistry control should shift from manually taking samples to a continuous evaluation of measured values and trend curves. The role of the chemical engineer will then be more of QA/QC in order to optimize the processes from the chemistry point of view.

    Cooling of the chiller condensers in supermarkets can be performed in different ways. To start with, the condensers can be cooled by use of outdoor air in dry coolers, but the ventilation air can also perform the cooling, totally or partially. In such a way the total or a part of the heating demand of the supermarket might be covered. A third alternative for condenser cooling is use of district cooling. However, in such a case the possibility to heat the supermarket by heat recovery is lost. The purpose of this study is to outline when district cooling offers the most advantageous alternative for condenser cooling in comparison to the other alternatives. This assessment is to be performed taking costs, electricity use and environmental impact into consideration separately. The results from calculations for a case supermarket show that the price for district cooling is generally to high for making it profitable for a supermarket to cool the condensers by district cooling. However, cooling the condensers by district cooling might lead to savings for the supermarket, both in terms of investments and use of electricity. This leads to the fact that cooling the condensers by district cooling could offer a profitable alternative for the supermarket, if the prices are adapted to this type of costumer. Hopefully, such a business could be profitable for the producers of district cooling as well. In addition, there are other advantages associated with condenser cooling by district cooling, which are hard to evaluate in economic terms. When it comes to the comparison of electricity use, it is shown that condenser cooling by district cooling is the alternative that uses least electricity in a national point of view, if the district cooling is produced by a deep-water source. In this comparison, the electricity used for production of district cooling and district heating is included as well. If district cooling is co-produced with district heating in heat pumps, the result is the opposite. However, this result is very much dependent upon how the use of electricity has been allocated (distributed) amongst the two products district cooling and district heating. In the environmental comparison the LCA-methodology has been applied. The results show that condenser cooling by district cooling leads to the least environmental impact in all the studied categories, if the district cooling is produced by deep-water source cooling and it is assumed that the used electricity is produced according to marginal production. However, condenser cooling by district cooling cannot compete with the other alternatives where heat recovery is applied if it is assumed that the used electricity is produced according to a Swedish production mix, no matter how the district cooling is produced.

    Stabilization of unbound layers is a method that enables the properties of road structures to be improved, for example the layer modulus of the sub base, by addition of binders. Traditional binders are cement, Merit 5000 (fine ground slag cement), lime and bitumen. The method is commonly in practice in Europe and has been also used occasionally for public roads in Sweden. Today there are examples where fly ashes (bio and coal based) have been used as binders in smaller roads for example in the counties of Uppsala, Soedermanland and also for other paved areas for heavy vehicles in the county of Vaestmanland and in Finland. These examples have mainly been carried out using an empirical approach. The objective of the project is to develop two applications as a base for full scale demonstration. One of them is a paved road and the other one is a private road with gravel as wearing course. The binders used are cement, Merit and fly-ash. Two sections of a road were used a reference. The work indicates that stabilization of unbound layers will improve the bearing capacity of the road construction significantly although the total depth of the structure is reduced. The design of the road structure was carried out in a conservative manner as there were no basis for a precise determination of the layer modulus. The developed applications are not frost lifting although their insulating properties are low and about the same as fine grained silt. The durability against frost and thaw cycles has been assessed and is expected to be acceptable. The fly ashes used will need addition of cement and Merit to perform well in frost and thaw tests. Applying both applications will result in a reduced depth of the structure and the sub-base layers can nearly be excluded. Life cycle cost calculations indicate that the cost of investment for a road construction using a stabilized layer are slightly higher than the cost of investment for the reference construction. This is probably due to the relative short sections to be used in the proposed demonstration sections. In total the calculations indicate that the life cycle cost are likely to be 15-25% lower for the applications than the reference over a considered time span of 40-years and a interest rate at 4%. An environmental assessment has been carried out, using guidelines for ashes, and indicates a low risk for contamination of the close surroundings. The performed design and environmental assessment has been summarized into a tender document consisting of typical sections, volumes, specification, program for control and also a permit application. In all; using the method of stabilization unbound layers is expected to enhance the bearing capacity of the road construction as a whole. The applications developed are expected to be durable against frost, will not heave due to frost and their insulation properties are not far from traditional materials in an unbound layer. The proposed solutions, for the paved road and private road, are expected to be favourable in a life cycle cost perspective (author)

    Biofuels like forest residues and bark would get more attractive incineration properties through decreased contents of metal ions and other elements that disturb the process or cause discharges that are harmful to health and environment. Bark in particular has considerably higher contents than stem wood of potassium and other elements that cause deposits, sintering and corrosion. In lime-kilns potassium, sodium, silicon and aluminium can cause additional problems with decreased lime reactivity, increased dead load and ring formation. Furthermore do biofuels generally form more nitrogen oxides in the smoke gases, due to high nitrogen contents. A first trial has been carried out in order to get an idea of how acid leaching - according to STFI-Packforsk's method for pulpwood chips - works for three types of wood fuels: chipped forest residues, bark and knot rejects from kraft cooking. The chips were steamed in a compression screw and leached with 6 kg H{sub 2}SO{sub 4}/t wood in 30 minutes at 80-100 deg C to pH ca 2.6. The procedure was repeated in a washing stage with water. The method seems to have the potential to decrease the content of problem substances in forest residues and bark to the level of the cleanest forest fuel quality today. The best reduction of the ash content, ca 50%, was obtained with forest residues. In bark, with its more than three times as high ash content (2.8% of wood), 35% of the ash was removed. Ca 60% of the potassium was leached out in the acidic stage. After the washing stage, about 85% had been removed in total. The treatment was also efficient on sodium which occur in high levels in kraft pulping reject. Other metal ions were removed to varying degrees up to ca 50% without washing stage. Some phosphorus and nitrogen were also leached out - 30 and 25% respectively from bark; 45 and 10% respectively from forest residues. The reduction of chlorine was estimated to 50% in forest residues and 80% in bark. The sulphuric acid used for leaching doubled the sulphur content of the fuels. This added sulphur was washed out in the subsequent washing stage. The leachate could be discharged after passing the biological treatment of the pulp mill or taken to the bark boiler after evaporation. Of three applications that have been evaluated briefly, the alternative where leached bark replaces oil in the limekiln and the leachate is discharged after treatment has the best economic potential (ROI 1 year). The leaching process needs development regarding process conditions and apparatus. The handling of leachates needs to be investigated further from economic and environmental points of views. The goal of the project (to evaluate if acidic leaching of wood fuels may be interesting - technically, economically and environmentally - to integrate with the kraft pulp mill) has been fulfilled. The main target group of the report are pulp mills and biofuel users.

    To assess [ 18 F]AV-1451 tau-PET (positron emission tomography) uptake patterns across the primary progressive aphasia (PPA) variants (logopenic, semantic, and agrammatic), examine regional uptake patterns of [ 18 F]AV-1451 independent of clinical diagnosis, and compare the diagnostic utility of [ 18 F]AV-1451, [ 18 F]-fluorodeoxygluclose (FDG)-PET and MRI (magnetic resonance imaging) to differentiate the PPA variants. We performed statistical parametric mapping of [ 18 F]AV-1451 across 40 PPA patients (logopenic-PPA = 14, semantic-PPA = 13, and agrammatic-PPA = 13) compared to 80 cognitively normal, Pittsburgh compound B-negative controls, age and gender matched 2:1. Principal component analysis of regional [ 18 F]AV-1451 tau-PET standard uptake value ratio was performed to understand underlying patterns of [ 18 F]AV-1451 uptake independent of clinical diagnosis. Penalized multinomial regression analyses were utilized to assess diagnostic utility. Logopenic-PPA showed striking uptake throughout neocortex, particularly temporoparietal, compared to controls, semantic-PPA, and agrammatic-PPA. Semantic-PPA and agrammatic-PPA showed milder patterns of focal [ 18 F]AV-1451 uptake. Semantic-PPA showed elevated uptake (left>right) in anteromedial temporal lobes, compared to controls and agrammatic-PPA. Agrammatic-PPA showed elevated uptake (left>right) throughout prefrontal white matter and in subcortical gray matter structures, compared to controls and semantic-PPA. The principal component analysis of regional [ 18 F]AV-1451 indicated two primary dimensions, a severity dimension that distinguished logopenic-PPA from agrammatic-PPA and semantic-PPA, and a frontal versus temporal contrast that distinguishes agrammatic-PPA and semantic-PPA cases. Diagnostic utility of [ 18 F]AV-1451was superior to MRI and at least equal to FDG-PET. [ 18 F]AV-1451binding characteristics differ across the PPA variants and were excellent at distinguishing between the variants. [ 18

    Full Text Available Å være lærerutdanner skiller seg fra andre stillinger innenfor høyere utdanning: Lærerutdanneren underviser både i fagstoff og i hvordan studentene kan lære bort og adaptere fagstoffet i klasserommet. Det at lærerutdanneren underviser i det å undervise, har implikasjoner for hvordan undervisningen planlegges, gjennomføres og analyseres i lærerutdanningen – undervisningens form blir en del av budskapet. Lærerutdannerens arbeid handler derfor om å utforme, velge og sette i spill aktiviteter og oppgaver som kan adaptere fag, forskning, didaktikk og teori til klasserom og profesjonen. Utforming og montasje av de ulike delene eller episodene i et undervisningsforløp kan betegnes som undervisningsforløpets dramaturgi. I denne artikkelen har jeg gjort en dramaturgisk analyse av tre lærerutdanneres undervisning for å identifisere og beskrive hvordan de bruker eksplisitte modelleringsformer, og hva som skjer når de bruker dem. I etterkant av den dramaturgiske analysen har jeg gjort en konvensjonell innholdsanalyse av intervjudata for å undersøke hvordan lærerutdannerne selv forklarer formålet og erfaringer med å bruke eksplisitt modellering i undervisningen. Analyse av tre lærerutdanneres undervisningspraksis sammenfattes i en modelleringsstige som visualiserer hvordan enkelte former for eksplisitte modelleringsformer tilbyr en egen sirkulær dramaturgi. Studien antyder og drøfter også på hvilken måte modelleringsstigen kan fungere som en dramaturgisk modell, som kan brukes som utgangspunkt for lærerutdanneres planlegging, gjennomføring og analyse av egen undervisning. Studien er et bidrag til å utvikle og forske på hvordan eksplisitte modelleringsformer kan brukes for å skape sammenheng mellom praktisk lærerarbeid og teoretisk metarefleksjon i lærerutdannerens undervisning. Innsamling av data er gjort i profesjonsverksted, som kan forklares som en læringsarena hvor lærerutdannere fra ulike fag samarbeider om

    The causal relationship between atrial and ventricular activities during human atrial fibrillation (AF) is poorly understood. This study analyzed the effects of an increase in atrial rate on the link between atrial and ventricular activities during AF. Atrial and ventricular time series were determined in 14 patients during the spontaneous acceleration of the atrial rhythm at AF onset. The dynamic relationship between atrial and ventricular activities was quantified in terms of atrioventricular (AV) coupling by AV synchrogram analysis. The technique identified n:m coupling patterns (n atrial beats in m ventricular cycles), quantifying their percentage, maximal length, and conduction ratio (= m/n). Simulations with a difference-equation AV model were performed to correlate the observed dynamics to specific atrial/nodal properties. The atrial rate increase significantly affected AV coupling and ventricular response during AF. The shortening of atrial intervals from 185 ± 32 to 165 ± 24 ms (P AV patterns with progressively decreasing m/n ratios (from conduction ratio = 0.34 ± 0.09 to 0.29 ± 0.08, P AV block and coupling instability at higher atrial rates were associated with increased ventricular interval variability (from 123 ± 52 to 133 ± 55 ms, P AV pattern transitions and coupling instability in patients were predicted, assuming the filtering of high-rate irregular atrial beats by the slow recovery of nodal excitability. These results support the role of atrial rate in determining AV coupling and ventricular response and may have implications for rate control in AF.

    Full Text Available Multiple epiphyseal dysplasia (MED is a congenital disorder of skeletal development that primarily affects the ends of long bones, causing progressive joint and bone inflammation and short stature. Mutations in several genes are responsible for pathogenesis of this disease. We are reporting a case of MED who presented with the complaints of multiple swelling of the joints which was associated with pain during movement for last seven years. The patient had flexion deformity of all the affected joints along with restriction of movement. These were associated with kyphosis, pectus carnitum, knock-knee and short stature. Radiological findings were suggestive of MED. Counseling was done with the parents regarding the etiology, progression and outcome of the disease.DOI: http://dx.doi.org/10.3329/bsmmuj.v5i1.11025 BSMMU J 2012; 5(1:57-60
