Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The 65-kD isoform of glutamic acid decarboxylase (GAD65) is a major autoantigen in type 1 diabetes. We hypothesized that alum-formulated GAD65 (GAD-alum) can preserve beta-cell function in patients with recent-onset type 1 diabetes.METHODS: We studied 334 patients, 10 to 20 years of age, with type 1 diabetes, fasting C-peptide levels of more than 0.3 ng per milliliter (0.1 nmol per liter), and detectable serum GAD65 autoantibodies. Within 3 months after diagnosis, patients were randomly assigned to receive one of three study treatments: four doses of GAD-alum, two doses of GAD-alum followed by two doses of placebo, or four doses of placebo. The primary outcome was the change in the stimulated serum C-peptide level (after a mixed-meal tolerance test) between the baseline visit and the 15-month visit. Secondary outcomes included the glycated hemoglobin level, mean daily insulin dose, rate of hypoglycemia, and fasting and maximum stimulated C-peptide levels.RESULTS: The stimulated C-peptide level declined to a similar degree in all study groups, and the primary outcome at 15 months did not differ significantly between the combined active-drug groups and the placebo group (P=0.10). The use of GAD-alum as compared with placebo did not affect the insulin dose, glycated hemoglobin level, or hypoglycemia rate. Adverse events were infrequent and mild in the three groups, with no significant differences.CONCLUSIONS: Treatment with GAD-alum did not significantly reduce the loss of stimulated C peptide or improve clinical outcomes over a 15-month period.

Leptin independently predicts development of future sepsis and determines survival in the acute phase
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objective: To determine if levels of the adipocyte-derived hormones leptin and adiponectin (adipokines) predict sepsis development and if intra-individual changes in circulating levels from baseline to the acute phase affect outcome.Method: A nested case-referent study within the framework of the Northern Sweden Health and Disease Study (NSHDS) and the Northern Sweden Maternity Cohort (NSMC). Patients aged 18 years or more with documented sepsis within 24 hours after admission to the intensive care unit (ICU) were included if they had participated in a health survey and donated blood samples prior to the sepsis event, and if possible also had stored plasma from the acute phase. Two matched referents free of known sepsis were selected for each case. Baseline and acute phase plasma leptin and adiponectin levels were determined. The associations between adipokines and sepsis and its severity and outcome were determined.Results: We identified 57 men and 97 women with a first-time sepsis event 6.5 years (median with IQR 7.7) after participation in the health survey, and 83% of them had also samples from the acute septic phase. Hyperleptinemia associated with a future sepsis event (OR 1.77, 95% CI 1.04-3.00, P=0.03), with stronger associations with severe sepsis and septic shock than with sepsis. High leptin levels were also associated with hospital death in the fully adjusted model. Leptin remained associated with sepsis in men (P=0.02), but not in women (P=0.36), after stratification and adjustment for BMI. In the acute phase, leptin increased more in men than in women (P=0.001), and high leptin levels were associated with increased risk for in-hospital death in women (OR 4.18, 95%CI 1.17-15.00, P=0.03), while being protective in men (OR 0.05, 95% CI 0.01-0.48, P=0.01). Adiponectin did not associate with sepsis or outcome.Conclusions: Hyperleptinemia independently predicted the development of sepsis, and an unfavourable outcome in men. Adiponectin was not associated with sepsis development.

Tidskriftsartikel (refereegranskat)abstract
- Background: Sepsis is a life-threatening condition and obesity is related to the clinical outcome. The underlying reasons are incompletely understood, but the adipocyte derived hormones leptin and adiponectin may be involved.Methods: Patients aged 18 years or more with documented first time sepsis events were included in a nested case-referent study if they had participated in previous health surveys. Two matched referents free of known sepsis were identified. Circulating levels of leptin and adiponectin were determined in stored plasma, and their impact on a future sepsis event and its outcome was evaluated.Results: We identified 152 patients (62% women) with a sepsis event and a previous participation in a health survey. Eighty-three % had also blood samples from the acute event. Hyperleptinemia at health survey associated with a future sepsis event (OR 1.77, 95% CI 1.04-3.00) and with hospital death. After adjustment for BMI leptin remained associated with sepsis in men, but not in women. High levels in the acute phase associated with increased risk for in hospital death in women (OR 4.18, 95% CI 1.17-15.00), while being protective in men (OR 0.05, 95% CI 0.01-0.48). Furthermore, leptin increased more from baseline to the acute phase in men than in women. Adiponectin did not predict sepsis and did not relate to outcome.Conclusions: Hyperleptinemia independently predicted the development of sepsis and an unfavourable outcome in men, and inertia in the acute response related to worse outcome.

Sensory ataxic neuropathy in golden retriever dogs is caused by a deletion in the mitochondrial tRNATyr gene
- 2009

Tidskriftsartikel (refereegranskat)abstract
- Sensory ataxic neuropathy (SAN) is a recently identified neurological disorder in golden retrievers. Pedigree analysis revealed that all affected dogs belong to one maternal lineage, and a statistical analysis showed that the disorder has a mitochondrial origin. A one base pair deletion in the mitochondrial tRNA(Tyr) gene was identified at position 5304 in affected dogs after re-sequencing the complete mitochondrial genome of seven individuals. The deletion was not found among dogs representing 18 different breeds or in six wolves, ruling out this as a common polymorphism. The mutation could be traced back to a common ancestor of all affected dogs that lived in the 1970s. We used a quantitative oligonucleotide ligation assay to establish the degree of heteroplasmy in blood and tissue samples from affected dogs and controls. Affected dogs and their first to fourth degree relatives had 0-11% wild-type (wt) sequence, while more distant relatives ranged between 5% and 60% wt sequence and all unrelated golden retrievers had 100% wt sequence. Northern blot analysis showed that tRNA(Tyr) had a 10-fold lower steady-state level in affected dogs compared with controls. Four out of five affected dogs showed decreases in mitochondrial ATP production rates and respiratory chain enzyme activities together with morphological alterations in muscle tissue, resembling the changes reported in human mitochondrial pathology. Altogether, these results provide conclusive evidence that the deletion in the mitochondrial tRNA(Tyr) gene is the causative mutation for SAN.

Tidskriftsartikel (refereegranskat)abstract
- This overview of four evidence maps is based on systematic reviews of assessment and interventions in social work practice. The aim was to investigate the evidence and evidence gaps within four important areas for social work research and practice. Descriptive data on search strategies and domains were collected from four evidence maps, on Social Assistance, Substance Dependence, Care for older adults respectively for persons with disabilities. The scientific quality and scientific evidence were assessed. Key findings were summarised by analyzing and discussing common and specific elements in the evidence maps. The overview was undertaken in close collaboration between researchers with expertise in the field and a government agency. The overview identified both evidence and evidence gaps with respect to effects and experiences of interventions and assessment methods in four evidence maps. Evidence maps provide a comprehensive picture of the state of social services research and can thereby be of use to both researchers and practitioners, and in the production of evidence based social work.

Tidskriftsartikel (refereegranskat)abstract
- We present here the complete primary structure of human gp330, the human variant of the principal kidney autoantigen causing Heymann membranous glomerulonephritis in rats. The deduced 4655 amino acid residues give a calculated molecular mass of 519636 Da for the mature protein and consists of a probable 25-amino-acid N-terminal signal peptide sequence, an extracellular region of 4398 amino acids, a single transmembrane-spanning domain of 23 amino acids, and an intracellular C-terminal region of 209 amino acid residues. Three types of cysteine-rich repeats characteristic of the low density lipoprotein receptor (LDLR) superfamily are present in human gp330. In the extracellular region, there are a total of 36 LDLR ligand-binding repeats, comprising four distinct domains, 16 growth factor repeats separated by eight YWTD spacer regions, and one epidermal growth factor-like repeat. No consensus cleavage sequence for the processing endoprotease furin is detected in human gp330. The intracellular tail contains not only two copies of the F(X)NPXY coated-pit mediated internalization signal characteristic of LDLR superfamily members, but also intriguing and potentially functional motifs including several Src-homology 3 recognition motifs, one Src-homology 2 recognition motif for the p85 regulatory subunit of phosphatidylinositol 3-kinase, and additional sites for protein kinase C, casein kinase II and cAMP-/cGMP-dependent protein kinase. There is approximately 77% amino acid identity between human and rat gp330 with minor differences between the extracellular and intracellular regions. Recently gp330 has been implicated in Ca2+ regulation in the parathyroid, the placenta, and the renal tubule, but its overall physiological and pathological role still remains uncertain.

Selective interaction of megalin with postsynaptic density-95 (PSD-95)-like membrane-associated guanylate kinase (MAGUK) proteins
- 2003
-
Ingår i: Biochemical Journal. - 0264-6021 .- 1470-8728. ; 373:2, s. 381-391

Tidskriftsartikel (refereegranskat)abstract
- Megalin is an integral membrane receptor belonging to the low-density lipoprotein receptor family. In addition to its role as an endocytotic receptor, megalin has also been proposed to have signalling functions. Using interaction cloning in yeast, we identified the membrane-associated guanylate kinase family member postsynaptic density-95 (PSD-95) as an interaction partner for megalin. PSD-95 and a truncated version of megalin were co-immunoprecipitated from HEK-293 cell lysates overexpressing the two proteins, which confirmed the interaction. The two proteins were found to be co-localized in these cells by confocal microscopy. Immunocytochemical studies showed that cells in the parathyroid, proximal tubuli of the kidney and placenta express both megalin and PSD-95. We found that the interaction between the two proteins is mediated by the binding of the C-terminus of megalin, which has a type I PSD-95/ Drosophila discs-large/zona occludens 1 (PDZ)-binding motif, to the PDZ2 domain of PSD-95. The PSD-95-like membrane-associated guanylate kinase ('MAGUK') family contains three additional members: PSD-93, synapse-associated protein 97 (SAP97) and SAP102. We detected these proteins, apart from SAP102, in parathyroid chief cells, a cell type having a marked expression of megalin. The PDZ2 domains of PSD-93 and SAP102 were also shown to interact with megalin, whereas no interaction was detected for SAP97. The SAP97 PDZ2 domain differed at four positions from the other members of the PSD-95 subfamily. One of these residues was Thr(389), located in the alphaB-helix and part of the hydrophobic pocket of the PDZ2 domain. Surface plasmon resonance experiments revealed that mutation of SAP97 Thr(389) to alanine, as with the other PSD-95-like membrane-associated guanylate kinases, induced binding to megalin.

Thermodynamical and structural properties of proteins and their role in food allergy
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Proteins are important building blocks of all living organisms. They are composed of a defined sequence of different amino acids, and fold into a specific three-dimensional, ordered structure. The three-dimensional structure largely determines the function of the protein, but protein function always requires motion. Small movements within the protein structure govern the functional properties, and this thesis aims to better understand these discrete protein movements. The motions within the protein structure are governed by thermodynamics, which therefore is useful to predict protein interactions.Nuclear magnetic resonance (NMR) is a powerful tool to study proteins at atomic resolution. Therefore, NMR is the primary method used within this thesis, along with other biophysical techniques such as Fluorescence spectroscopy, Circular Dichroism spectroscopy and in silico modeling.In paper I, NMR in combination with molecular engineering is used to show that the folding of the catalytical subdomains of the enzyme Adenylate kinase does not affect the core of the protein, and thus takes a first step to linking folding, thermodynamic stability and catalysis.In paper II, the structure of the primary allergen from Brazil nut, Ber e 1, is presented along with biophysical measurements that help explain the allergenic potential of the protein.Paper III describes the need for a specific Brazil nut lipid fraction needed to induce an allergenic response. NMR and fluorescence spectroscopy is used to show that there is a direct interaction between Ber e 1 and one or several components in the lipid fraction.

Mångreligiositet och sekularitet i svenskt polisväsende, vård, skola och offentlig förvaltning : en forskningsöversikt
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Under de senaste decennierna har Sverige genomgått stora demografiska och politiska förändringar. Tillsammans har dessa inneburit att Sverige idag samtidigt är ett av Europas mest sekulariserade och mest mångreligiösa länder. Den snabba demografiska förändring Sverige har genomgått har ställt många inför nya, stora och i vissa fall skyndsamma kunskapsbehov samtidigt är forskningen om situationen delvis eftersatt. I denna rapport identifieras hur den nya situationen relaterar till det lagstadgade uppdrag som svenskt polisväsende, vård, skola och offentlig förvaltning har. Den forskning som gjorts inom dessa områden sammanfattas och de viktigaste forskningsbehoven identifieras.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I rapporten kan du ta del av bedömningen som görs av situationen för bestånd som regleras inom ramen för EU:s gemensamma fiskeripolitik (GFP). Bedömningarna baseras på det forskningssamarbete och den rådgivning som sker inom det Internationella Havsforskningsrådet (ICES). Sammantaget redovisas tillståndet för 107 bestånd av 48 fisk- och skaldjursarter.De bestånd som förvaltas nationellt baseras på de biologiska underlagen, och rådgivningen i huvudsak på den forskning och övervakning samt analys som bedrivs av Institutionen för akvatiska resurser vid Sveriges lantbruksuniversitet (SLU Aqua) samt yrkesfiskets rapportering.Rapporten är en beställning från Havs- och vattenmyndigheten (HaV) till Sveriges lantbruksuniversitet (SLU) och utgör ett viktigt kunskapsunderlag till myndighetens arbete. Den uppfyller de krav som finns inom EU:s gemensamma fiskeripolitik om att basera förvaltningen på bästa tillgängliga vetenskap. Denna rapport är också ett stöd till det arbete som beskrivs närmare i strategin för framtidens fiske och tillhörande handlingsplaner för vattenbruk, yrkes- och fritidsfiske som HaV och Jordbruksverket har tagit fram i dialog med fiskets och vattenbrukets intressenter.

- We describe a 2-year-old boy with chondrodysplasia punctata (CDP). The boy was exposed to phenytoin, in combination with carbamazepine, during pregnancy. There has been previous evidence for a connection between phenytoin exposure during pregnancy and chondrodysplasia punctata. The boy had clinical and some radiological characteristic features of CDP, of the tibia-metacarpal type. We know of no other report on a child exposed to phenytoin during pregnancy who developed CDP of this type.

Tidskriftsartikel (refereegranskat)abstract
- Domino liver transplantation (DLT) using grafts from patients with familial amyloidotic polyneuropathy (FAP) is an established procedure at many transplantation centers. However, data evaluating the long-term outcome of DLT are limited. The aim of the present study was to analyze the risk of de novo polyneuropathy, possibly because of amyloidosis, and the patient survival after DLT. At our department, 28 DLT using FAP grafts were conducted between January 1997 and December 2005. One patient was twice subjected to DLT. Postoperative neurological monitoring of peripheral nerve function was performed with electroneurography (ENeG) in 20 cases. An ENeG index based on 12 parameters was calculated and correlated to age and/or height. Three patients developed ENeG signs of polyneuropathy 2-5 years after the DLT, but with no clinical symptoms. The 1-, 3- and 5-year actuarial patient survival in hepatocellular carcinoma (HCC) patients (n = 12) and non-HCC patients (n = 15) was 67%, 15%, 15% and 93%, 93%, 80%, respectively (P = 0.001). Development of impaired nerve conduction in a proportion of patients may indicate that de novo amyloidosis occurs earlier than previously expected. Survival after DLT was excellent except in patients with advanced HCC.

Considerations and consequences of allowing DNA sequence data as types of fungal taxa
- 2018

Ingår i: IMA Fungus. - : INT MYCOLOGICAL ASSOC. - 2210-6340 .- 2210-6359. ; 9:1, s. 167-185

Tidskriftsartikel (refereegranskat)abstract
- Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Women with type 1 diabetes face particular demands in their lives in relation to childbearing. During pregnancy, in order to optimize the probability of giving birth to a healthy child, their blood glucose levels need to be as normal as possible. After childbirth, they experience a 'double stress': in addition to the ordinary challenges they face as new mothers, they also need to focus on getting their blood glucose levels normal. To improve self-management of diabetes and overall well-being in women with type 1 diabetes, a person-centered web-based support was designed to be tested in a randomized controlled trial (RCT) to be used during pregnancy and early motherhood. This protocol outlines the design of this RCT, which will evaluate the effectiveness of the specially designed web-based support for mothers with type 1 diabetes in Sweden.Methods: The study is designed as an RCT. The web support consists of three parts: 1) evidence-based information, 2) a self-care diary, and 3) communication with peers. The primary outcome is general well-being evaluated with the Well-Being Questionnaire short version (W-BQ12) and diabetes management evaluated with the Diabetes Empowerment Scale, short version (SWE-DES). Women attending six hospital-based antenatal care centers in Sweden are invited to participate. The inclusion period is November 2011 to late 2014. The allocation of participants to web support (intervention group) and to usual care (control group) is equal (1:1). In total, 68 participants in each group will be needed to reach a statistical power of 80% with significance level 0.05.Discussion: The web support is expected to strengthen the women's personal capacity and autonomy during pregnancy, breastfeeding, and early motherhood, leading to optimal well-being and diabetes management.

- AIM: The aim of this study is to find out how common miscarriages are among women who have delivered a child. METHODS: The numbers of deliveries and miscarriages were extracted from the Swedish Medical Birth Register between 1983 and 2003. Linear regression was performed in order to investigate whether the increasing mean age of mothers or differences in pregnancy identification methods could explain the increased frequency of miscarriage. RESULTS: The reported number of miscarriages increased each year during the 21-year period, with a marked increase between 1991 and 1993 and only a slight increase during the final 10 years. For primiparous women, the frequency of reported miscarriages per delivery increased from 8.6% in 1983 to 13.9% in 2003. The corresponding figures for 2-parous women showed an increase from 14.5% to 21.3% respectively. Women aged 30-34 years had an odds ratio of 1.43 (95% CI 1.40-1.45) to suffer spontaneous abortion compared to the age group 25-29 years. Linear regression showed that an increase in mean age at delivery could only partly explain the increase in the frequency of reported miscarriages. A possible explanation could be differences in methods of identifying early pregnancy. CONCLUSION: Of all women who deliver a child, nearly 20% have experienced previous miscarriage. The increased mean age of women could only explain a small portion of the seen increase in miscarriage. The marked increase from 1991 to 1993 is interesting. Possible reasons for the increase are discussed.

- We investigated the effect of a changed routine to identify women with a nonviable pregnancy, in order to utilize health care resources more efficiently during office hours rather than relying on emergency care services. From hospital register data about where and when women with miscarriages were treated, there was a significant trend during a nine-year period for miscarriages to be more rarely diagnosed (p-value<0.001) in the emergency ward after office hours. The proportion of miscarriages that were diagnosed and handled at the emergency ward decreased from 31% in 2001 to 17% in 2009. Furthermore, the number of women showing up with bleeding at the emergency ward, but who also had a normal viable pregnancy, declined during the same period (p-value<0.01). Women with suspected miscarriage benefit from structured information and standardized management and can effectively be scheduled for day-time assessment including ultrasound with a concomitant reduced need for emergency services.

- Background: Women's grief after miscarriage is substantial and important. Women who experience early miscarriage do not constitute a homogenous group. The aim of this study is to measure whether a structured follow-up visit to a midwife (group 1) at 21-28 days after early miscarriage could reduce the women's grief, measured using the perinatal grief scale Swedish short version (PGS) after a further 3 months (i.e. 4 months after the miscarriage), compared to a regular follow-up visit to a midwife (group 2).Methods: We performed an open randomized study of women who experienced early miscarriage (n = 88). The midwife's attitude in group 1 came from Swanson science theory of midwifery. In group 2, the women were offered only the ordinary type of consultation at a regular visit. A questionnaire with the PGS was used in both groups. Four months after the miscarriage, a second questionnaire with the same perinatal grief scale was sent by post.Results: There was a 30% greater reduction in grief in group 1 than that in group 2, when comparing the first and second measurements (not significant). The biggest differences were in the subscales active grief and difficulty in coping. Women with the subdiagnosis missed abortions had, as a group, significantly higher PGS scores at both visits, especially in active grief and difficulty in coping, regardless of the type of follow-up visit.Conclusions: A structured follow-up visit did not, in comparison with a regular follow-up visit, imply any significant reduction in grief as measured using the PGS scale. However, the subgroup missed abortion had more extensive grief than the other women with miscarriage. Structured follow-up visits are not imperative for all women with early miscarriage.

- Women who lose an early pregnancy are shocked when they are first given the information that they have miscarried. Later they feel guilt and emptiness. Heideggerian interpretive phenomenology has been used with 13 women from southwest Sweden to uncover their lived experience of miscarriage. Women plan their future with a child during early pregnancy. When miscarriage occurs it is not a gore, an embryo, or a fetus they lose, it is their child. They feel that they are the cause of the miscarriage through something they have done, eaten, or thought. They feel abandonment and they grieve for their profound loss; they are actually in bereavement.

- Reoccurring symptoms and persistent problems that continue post treatment can becharacteristic of the vaginal infections Bacterial Vaginosis (BV) and recurrent vulvovaginalcandidiasis (RVVC). The purpose of this study was to describe women’s lifeexperiences in managing the symptoms of bacterial vaginosis and Candida. Sixteenwomen were recruited and participated in an interview study when they contacted aSwedish gynecology clinic with vaginal complaints that ranged from and includedabnormal discharge, irritation itching along with serious malodor. An interpretivephenomenological approach was used with an individual interview to get a more intimateunderstanding of the women experiencing these problems. The finding of thisstudy shows that managing the recurrent symptoms of the infections remains to be achallenge for women as it has a clearly negative impact on the quality of their lives.Four themes developed: frustration and mood disorders, intimacy changes in the relationship,exposure, hope and relief. The women had high hopes of eliminating thesymptoms within the six-month study period. The treatment program, with itswell-developed guidelines and continuity of care within the context of the studygreatly improved the quality of life of these women. Women had feelings of frustrationand anxiety when nothing could cure their problem while they had also a greathope to get rid of the symptoms with a long striking treatment. Well-developedguidelines and continuity of care can help these women to have an improved qualityof life.

Miscarriage : women’s experience and its cumulative incidence
- 2006

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Many women experience miscarriage every year. Every fourth woman who has given birth reports that she has previous experience of miscarriage. In a study of all women in the Swedish Medical Birth Register 1983-2003, we found that the number of cases of self reported miscarriage had increased in Sweden during this 21 year period. This increase can be explained by the introduction of sensitive pregnancy tests around 1990, as well as an increase in the mean age of the mothers, by approximately 3 years, during the observation period. The risk of miscarriage is 13% with the first child. With subsequent pregnancies, the risk of miscarriage is 8%, 6% and 4% with the second, third and fourth child, respectively.Thirteen of these women who had suffered a recent miscarriage were interviewed four months later, and their feelings of guilt and emptiness were explored. Their experience was that they wanted their questions to be answered, and that they wanted others to treat them as the mothers to be that they felt themselves to be. They also experienced the need for time to grieve their loss.Measurement of grief by means of the Perinatal Grief Scale (PGS) is used in research but has also been proposed for clinical use. We have translated this psychological instrument to Swedish, back-translated and tested it in a small pilot study. In a randomized controlled study, women with early miscarriage were allocated, either to a structured visit (study group) or a regular visit (control group) to a midwife. The structured visit was conducted according to the Swanson caring theory. We could conclude that the structured visit had no significant effect on grief compared to the regular visit, as measured using the PGS. However, women with the sub-diagnosis missed abortion have significantly more grief four months after early miscarriage, regardless of visit type.We also performed a content analysis of the tape-recorded structured follow-up visit. The code-key used was Bonanno and Kaltman’s general grief categorization. Women’s expression of grief after miscarriage was found to be very similar to the grief experienced following the death of a relative. Furthermore, the grief was found to be independent of number of children, women’s age, or earlier experience of miscarriage.Conclusions: Every fourth woman who gives birth reports that she has also experienced early miscarriage. The experience of these women is that they have suffered a substantial loss and their reaction is grief similar to that experienced following the death of a relative.

- Objective: The aim of this paper is to describe the process of developing web information on miscarriage based on scientific evidence, for women and couples in Sweden experiencing miscarriage. Method: A participatory design was used which included researchers, professional xperts and users. A participatory design was used involving researchers, professional experts and users. The information was developed in six stages: 1) identifying the needs of information; 2) identifying and constructing the main areas of information and its paths; 3) identifying and inviting experts for revision; 4) developing the text; 5) reviewing the text; 6) design and structuring for adaption to website. Results: The text of information developed gradually based on the seven steps. The final text comprised three parts: 1) what is miscarriage; 2) experiences of miscarriage; 3) processing and lanning for new pregnancy. Conclusion: Using participatory design was time and resource consuming, however it was functional for producing appropriate information for the target group. The developed evidence based facts text is assumed to be a complement to the information that is provided by the health care system.

- Background. Grief is a normal phenomenon but showing great variation depending on cultural and personal features. Bonanno and Kaltman have nonetheless proposed five aspects of normal grief. The aim of this study was to investigate if women with miscarriage experience normal grief. Material and methods. Content analyses of 25 transcribed conversations with women 4 weeks after their early miscarriages were classified depending on the meaning-bearing units according to Bonanno and Kaltman's categories. In the factor analyses, these categories were compared with the Perinatal Grief Scale and women's age, number of children and number of miscarriages, and gestational weeks. Results. Women with miscarriage fulfill the criteria for having normal grief according to Bonanno and Kaltman. All of the 25 women had meaning-bearing units that were classified as cognitive disorganization, dysphoria, and health deficits, whereas disrupted social and occupational functioning and positive aspects of bereavement were represented in 22 of 25 women. From the factor analysis, there are no differences in the expression of the intensity of the grief, irrespective of whether or not the women were primiparous, younger, or had suffered a first miscarriage. Conclusion. Women's experience of grief after miscarriage is similar to general grief after death. After her loss, the woman must have the possibility of expressing and working through her grief before she can finish her pregnancy emotionally. The care-giver must facilitate this process and accept that the intensity of the grief is not dependent on the woman's age, or her number of earlier miscarriages.

- Introduction: Women's emotions and grief after miscarriage are influenced not only by the context in which the miscarriage occurred but also by their past experience, the circumstances around the miscarriage and their future prospects. Their emotions therefore express a specific form of grief. Normally the time needed to work through the loss varies. A number of different scales, measuring women's emotions and grief after miscarriage have been published. One instrument that measures the specific grief, such as the grief after miscarriage is the Perinatal Grief Scale (PGS) that was designed to measure grief after perinatal loss and has good reliability and validity. Aims: The purpose of this study was to translate the PGS into Swedish and to use the translation in a small pilot study. Material and method: The original short version of the PGS was first translated from English into Swedish and then back-translated into English, using different translators. During translation and back-translation, not only the linguistic and grammatical aspects were considered but also cultural differences. The Likert 5-point and a 10-point scale were tested in a pilot study where 12 volunteers anonymously answered the PGS twice. The intra-personal correlations were compared and analysed with weighted κ-coefficient. Findings: In all, five different versions were tested before the final Swedish version was established. The weighted κ-coefficient for the volunteers was 0.58, which is regarded as representing good reproducibility. Conclusion: The PGS was translated successfully into Swedish and could be used in a Swedish population. As this work is rather time-consuming we therefore wish to publish the Swedish version so that it may be used by other researchers.

- We present results from measurements of the subthreshold lateral spontaneous emission profile in 1.3-mu m wavelength ridge waveguide InGaNAs quantum-well lasers using a scanning near-field optical microscopy technique. The measurements reveal the presence of significant lateral carrier diffusion which has a profound effect on the temperature dependence of the threshold current. This effect is frequently omitted when the characteristic temperature of the threshold current is considered.

Tidskriftsartikel (refereegranskat)abstract
- We present an experimental and theoretical investigationof the temperature dependence of the threshold current fordouble quantum well GaInNAs–GaAs lasers in the temperaturerange 10 C–110 C. Pulsed measurements of the threshold current have been performed on broad and narrow ridge wave guide(RWG) lasers. The narrow RWG lasers exhibit high characteristic temperatures (T0)of 200 K up to a critical temperature (Tc), above which T0 is reduced by approximately a factor of 2. The T0-values for broad RWG lasers are significantly lower than those for the narrow RWG lasers, with characteristic temperatures on the order of 100 (60) K below (above). Numerical simulations, using a model that accounts for lateral diffusion effects, show good agreement with experimental data and reveal that a weakly temperature dependent lateral diffusion current dominates thethreshold current for narrow RWG lasers.
