2. 1. Hyperglycemia and Focal Brain Ischemia : Clinical and Experimental Studies

   Author : Nasim Farrokhnia; Andreas Terént; Fredrik Lennmyr; Elisabeth Björk; Henrik Hagberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; cerebrovascular disorders; diabetes mellitus; hyperglycemia; infarction; middle cerebral artery; ischemia; mitogen-activated protein kinases; mortality; rats; reactive oxygen species; reperfusion; signal transduction; therapeutics; Invärtesmedicin; Internal medicine; Invärtesmedicin;

   Abstract : Diabetes is a major risk factor for ischemic stroke and is associated with increased mortality. Additionally, hyperglycemia, a common complication in acute stroke, is associated with poor outcome. READ MORE

4. 2. Probing brain microstructure with multidimensional diffusion MRI: Encoding, interpretation, and the role of exchange

   Author : Björn Lampinen; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Diffusion; Human; Brain; Microstructure; Fysicumarkivet A:2021:Lampinen;

   Abstract : Diffusion MRI (dMRI) is a non-invasive probe of human brain microstructure. It is a long-standing promise to use dMRI for ‘in vivo histology’ and estimate tissue quantities. However, this faces several challenges. First, the microstructure models used for dMRI data are based on assumptions that may cause erroneous interpretations. READ MORE

5. 3. Post-Ischemic Housing Conditions Influence On Gene Transcription And Translation After Permanent Focal Brain Ischemia In Rats

   Author : Li-Ru Zhao; Sektion IV; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; brain-derived neurotrophic factor; mRNA; nerve growth factor-induced gene A; corticosteroid receptors; in situ hybridization; Neurologi; neurophysiology; Neurology; neuropsychology; brain ischemia; enriched environment; neuropsykologi; neurofysiologi;

   Abstract : Enriched environment (EE) housing significantly ameliorates neurological deficits induced by cortical brain ischemia without changing infarction size, suggesting that EE-related functional benefits are associated with neuronal plasticity events in the remaining tissue. Brain-derived neurotrophic factor (BDNF), nerve growth factor-induced gene A (NGFI-A) and corticosteroid receptors (mineralocorticoid receptor, MR; glucocorticoid receptor, GR) have been demonstrated to be involved in brain plasticity.

6. 4. Early Risk Stratification, Treatment and Outcome in ST-elevation Myocardial Infarction

   Author : Erik Björklund; Bertil Lindahl; Lars Wallentin; Ulf Näslund; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Acute myocardial infarction; Thrombolysis; Troponin; Electrocardiography; Natriuretic peptide; Prognosis; Prehospital thrombolysis; Treatment delay; Mortality; Registry; Clinical trial; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Abstract : We evaluated, in patients with ST-elevation myocardial infarction (STEMI) treated with thrombolytics, admission Troponin T (tnT), ST-segment resolution and admission N-terminal pro-brain natriuretic peptide (NT-proBNP) for early risk stratification as well as time delays and outcome in real life patients according to prehospital or in-hospital thrombolytic treatment. Also, baseline characteristics, treatments and outcome in patients enrolled in the ASSENT-2 trial in Sweden and in patients not enrolled were evaluated. READ MORE

7. 5. Outcome after modern neurosurgical care and formalised rehabilitation following severe brain injury

   Author : Ann Sörbo; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; outcome; severe brain injury; life satisfaction; early formalised rehabilitation; change over time; decompressive craniectomy; long-term follow-up;

   Abstract : Aims: The overall aims were to evaluate the results of the treatment concepts for severe brain injury including decompressive craniectomy (DC), early rehabilitation and long-term follow-up, primarily according to the psychosocial consequences of the brain damage and life satisfaction. The first study was a cross-sectional study to assess and compare the consequences for outcome for two groups with severe traumatic brain injury (TBI) or subarachnoid haemorrhage (SAH), one group that received early, long-term formalised rehabilitation and the other that received late or no formalised rehabilitation.
