- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Bottenfaunaundersökning har genomförts i 17 vattendrag i Örebro län år 2011. Undersökningen är ett led i länets arbete med karakterisering av vattendrag enligt EU:s ramdirektiv för vatten och bevarande av biologisk mångfald. Sammanvägd Ekologisk status: Enligt den bedömning som utförts så är det Hög status i Albäcksån, Gränssjöälven, Hyttbäcken, Limmingsbäcken och Sirsjöbäcken, God status i Dammsjön utlopp, Lankälven, Malälven, Mogruvälven, Ringshyttebäcken, Smygarebäcken och Tomsjöälven, Måttlig status i Långboån och Sågån, Otillfredsställande status i Estaboån, Orobäcken och Örlaxbäcken. Inget av vattendragen visade sålunda Dålig status.

Anaesthetizing children-From a nurse anaesthetist's perspective-A qualitative study
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Aim: The aim of this study was to describe nurse anaesthetists' experiences of encountering and caring for children in connection to anaesthesia.Design: Qualitative design.Methods: Sixteen written narratives based on eight nurse anaesthetists' experiences of meeting children was analysed using qualitative content analysis.Results: The overarching theme was: "anaesthetizing children is a complex caring situation, including interactions with the child and parents as well as ensuring patient safety, affected by the perioperative team and organizational prerequisites". The nurses stated that in their interaction with the family, their goal was to ensure that children and parents felt secure and calm. "Striving to work in confidence" underlined the team and organizational influences. Encountering children involves more than knowledge about technical equipment, procedures and drugs. Knowledge about children's development and fears and parents' needs are essential for an optimal caring situation. Organizations need to realize that extra time, skills and resources are needed to safely anaesthetize children.

- Microorganisms produce chelating agents, such as siderophores and other ligands, which allow them to mobilize and scavenge essential elements from the environment when bioavailability is low. To better understand the effects of biologically mediated leaching of metals from mine waste, Pseudomonas fluorescens was cultivated in the presence of processed ore from the former uranium mine in Ranstad, southern Sweden. Light conditions, the concentration of the mineral source and oxygen availability were varied. The presence of ore in the culture flasks enhanced bacterial growth and raised the pH of the culture medium. Increasing the amount of ore or enhancing aeration of the medium further encouraged cell growth and pH rise. Bacteria mobilized Fe, Ni and Co from the ore. Fe-siderophore complexes were detected and estimated to be present at approximately 9 μm. In the presence of bacteria and light, dissolved Fe and U concentrations were higher compared to dark conditions. Increasing the amount of ore resulted in higher dissolved Ni concentrations but lower dissolved Fe, most likely due to precipitate formation. Data from this study support siderophore production by bacteria that allowed mobilization of essential nutrients from the processed ore. However, the availability of potentially toxic metals like Ni and U may also be enhanced. Microbial-promoted mobilization could contribute to leaching of toxic metals in current and historic mining areas. This process should be considered during design and implementation of remediation projects where trace metals are of environmental concern.

- Nordic ophthalmologists and vision scientists are active in many fields of eye research. This is most evident at the biannual Nordic Congress of Ophthalmology, most recently held in Malmö in June 2004. The authors here review some of the research in vision and ophthalmology presented at this meeting or published recently by Nordic scientists. This paper does not represent a comprehensive review of all Nordic research in the field, but attempts to give an overview of some of the activities underway in eye research in this part of the world.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND/AIMS:During the last decade, improved neonatal care has resulted in increased survival of the most immature infants and improved health of more mature infants. We hypothesise that this has affected incidence and treatment of retinopathy of prematurity (ROP), enabling guidelines for screening to be modified.METHODS: In Sweden, all infants with gestational age (GA) at birth ≤30 weeks are screened for ROP. Results are registered in a web-based register, Swedish National ROP Register, with a coverage rate of 97%. Incidence of ROP and frequency of treatment, aspects on natural course of ROP and number of examinations, are calculated in relation to GA at birth in infants born during 2008-2017.RESULTS: Of 7249 infants, 31.9% (2310) had ROP and 6.1% (440) were treated. No infant with GA 30 weeks was treated. Incidence of ROP remained similar, but frequency of treatment increased (p=0.023). Over time, GA and birth weight were reduced in infants with ROP and with treated ROP. In the most immature infants, postmenstrual age was lower and postnatal age was higher when any ROP and stage 3 ROP were first detected (p<0.001). At treatment, postmenstrual but not postnatal age of the infant was associated with GA (p<0.001). During the 10-year period, 46 038 examinations were performed.CONCLUSION: Modification of Swedish guidelines is proposed, including only infants with a GA of <30 weeks and postponing the first examination with 1 week in infants with GA 26-29 weeks. This would spare many infants from stressful examinations and reduce eye examinations with at least 20%.

- Purpose : Description of ten years of national ROP-screening and treatment in Sweden and evaluation of the national screening program for ROP.Methods : The study is based on a national register for ROP, SWEDROP, with around 96% coverage. According to Swedish guidelines, all infants born at 30 weeks gestational age (GA) or less, as well as children born later but being extremely sick, should be screened for ROP during the neonatal period. Birth data are validated in the Swedish neonatal quality register, SNQ.Results : During the ten-year period between 2008 and 2017, 7257 infants with a GA of 30 weeks or less were registered in SWEDROP and 46.294 examinations were performed, of which 5.328 (11.5%) in infants born in gestational week 30. Mean GA was 27.6 w (range 21-30 w) and mean BW was 1116 g (range 390-2405 g). Overall, during the ten years, ROP was found in 31.8% (range 26.8-36.8%) and treatment for ROP was performed in 6% (range 4.1-7.7%) of the screened infants. Only nine infants with GA 28 w and four with GA 29 w were treated for ROP. No infant with GA 30 w was treated. Eighty-two per cent (361/441) of the treated infants had laser only and 17.7% (78/441) were treated with Anti-VEGF, alone (17 infants) or in combination with laser and/or other treatment.Conclusions : SWEDROP is a national register for ROP with a high national coverage. The incidence of ROP and frequency of treatment remained similar over the ten-year period. Only 13 infants born at 28 – 29 weeks GA and no child born at 30 w GA were treated for ROP. Modification of guidelines is considered, with lowering the upper limit of screening with one week, i.e. to less than 30 weeks GA. During the ten-year study period, this would have resulted in a reduction of 1680 infants (23.2%) screened for ROP and of 5.328 (11.5%) examinations.
