Högskolebibliotekets roll i en inkluderande lärandemiljö : slutrapport
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Slutrapport från projektet "Högskolebibliotekets roll i en inkluderande lärandemiljö" vars syfte var att förtydliga vilken roll högskolebiblioteket spelar för breddad rekrytering och retention, samt att öka kunskapen och medvetenheten om detta bland bibliotekspersonalen. I rapporten ges exempel på arbetsformer för att utveckla bibliotekets bemötande och pedagogiska verksamhet gentemot en heterogen studentgrupp.

- Vitamin D and parathyroid hormone (PTH) constitute the main regulators of systemic calcium homeostasis. As well as its calcaemic effects, active vitamin D3(1,25(OH)2D3) has a direct regulatory role on parathyroid cells. Active vitamin D3 acts via its receptor (VDR), and binding of the ligand-receptor complex to specific promoter regions of the PTH gene inhibits transcription. Active vitamin D3 constitutes a principal regulator of parathyroid cell growth, and polymorphism in the VDR gene has recently been related to bone mineral density and suggested as predisposing to osteoporosis. Impaired effects of active vitamin D3 may contribute to the relatively enhanced secretion and cell proliferation seen in hyperparathyroidism (HPT). Indeed, VDR dysfunction, of essentially unknown character, has been demonstrated in the pathological parathyroid tissue of primary HPT as well as HPT secondary to uraemia. Consistent with the essential role of active vitamin D3 in parathyroid regulation, the VDR gene polymorphism was studied in 90 postmenopausal women with primary hyperparathyroidism. The VDR genotype bb was found in 60.0% of HPT patients and in 33.3% of the postmenopausal female controls (P < 0.001). As the b allele has been linked to decreased transcriptional activity or messenger RNA stability, reduced VDR expression may impede regulatory actions of vitamin D and may contribute to parathyroid tumorigenesis in these patients.

- Background: The clinical importance of immediate coronary angiography, with potentially subsequent percutaneous coronary intervention (PCI), in out-of-hospital cardiac arrest (OHCA) patients without ST-elevation on the ECG is unclear. In this study, we assessed feasibility and safety aspects of performing immediate coronary angiography in a pre-specified pilot phase of the 'DIrect or Subacute Coronary angiography in Out-of-hospital cardiac arrest' (DISCO) randomized controlled trial (ClinicalTrials.gov ID: NCT02309151). Methods: Resuscitated bystander witnessed OHCA patients > 18 years without ST-elevation on the ECG were randomized to immediate coronary angiography versus standard of care. Event times, procedure related adverse events and safety variables within 7 days were recorded. Results: In total, 79 patients were randomized to immediate angiography (n = 39) or standard of care (n = 40). No major differences in baseline characteristics between the groups were found. There were no differences in the proportion of bleedings and renal failure. Three patients randomized to immediate angiography and six patients randomized to standard care died within 24 h. The median time from EMS arrival to coronary angiography was 135 min in the immediate angiography group. In patients randomized to immediate angiography a culprit lesion was found in 14/38 (36.8%) and PCI was performed in all these patients. In 6/40 (15%) patients randomized to standard of care, coronary angiography was performed before the stipulated 3 days. Conclusion: In this out-of-hospital cardiac arrest population without ST-elevation, randomization to a strategy to perform immediate coronary angiography was feasible although the time window of 120 min from EMS arrival at the scene of the arrest to start of coronary angiography was not achieved. No significant safety issues were reported.
