1. 1. Improving venous blood specimen collection practices : method development and evaluation of an educational intervention program

   Författare :Karin Bölenius; Christine Brulin; Kjell Grankvist; Johan Söderberg; Ewa Idvall; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Education; Experiences; Guideline adherence; Haemolysis; Intervention; Patient safety; Phlebotomy; Practical skills; Preanalytical errors; Primary healthcare; Questionnaires; Reliability and validity; Venous blood specimen collection; omvårdnadsforskning med medicinsk inriktning; Caring Sciences; Clinical Chemistry; klinisk kemi;

   Sammanfattning : Background: About 60%–80% of decisions regarding diagnosis and treatment are based on laboratory test results. Low adherence to venous blood specimen collection (VBSC) guidelines may lead to erroneous or delayed test results, causing patient harm and high healthcare costs. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; Hydrology; Hydrologi; Hydrology; Hydrologi;

   Sammanfattning : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. LÄS MER

5. 4. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT

   Författare :Susanna Jakobson Mo; Katrine Åhlström Riklund; Anne Larsson Strömvall; Lars Forsgren; Rimma Axelsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; SPECT; 123I-FP-Cit; 123I-IBZM; dopamine; parkinsonism; Parkinson’s disease; multiple system atrophy; progressive supranuclear palsy; Radiology; radiologi;

   Sammanfattning : Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis.
