    Dynamisk bedömning av ordförråd: En jämförelse mellan enspråkiga barn och flerspråkiga barn2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

     

    Bakgrund

     

    Forskning har visat att flerspråkiga barn riskerar missvisande resultat när de bedöms med statiska tester. Detta då statiska tester i regel är normerade på en enspråkig population. Som alternativ till statiska tester har dynamisk bedömning föreslagits. Dynamisk bedömning undersöker barns inlärningspotential.

     

    Syfte

     

    Syftet med studien var att jämföra flerspråkiga barns och enspråkiga barns prestation på ett statiskt test av ordförråd med deras prestation på en dynamisk bedömning av ordförråd. Förfarandet vid den dynamiska bedömningen är en sedan tidigare beprövad metod som testas med barn ur svenska förskoleklasser.

     

    Metod

     

    Studien omfattade 29 barn från olika skolor i en medelstor norrländsk kommun. Barnen var flerspråkiga och enspråkiga och hade alla börjat i svensk förskoleklass höstterminen 2018. Datainsamlingen skedde med ett statiskt pretest i form av Pearson Peabody Vocabulary Test-III för att därefter genomföra en dynamisk bedömning gällande ordförråd med de ord barnen inte kunde samt de ord barnen kunde.

     

    Resultat

     

    Resultatet visade att de enspråkiga barnen presterade signifikant bättre än de flerspråkiga i det statiska pretestet PPVT-III. I den dynamiska bedömningen kunde inga signifikanta skillnader påvisas.

     

    Slutsats

     

    Resultatet av den föreliggande studien är att flerspråkiga och enspråkiga barn presterade likvärdigt i den dynamiska bedömningen oavsett hur lågt de presterade i PPVT-III. Detta skiljer sig mot de resultat som uppvisas vid statisk testning där enspråkiga barn får signifikant bättre resultat än flerspråkiga barn.

    Blood flow of ophthalmic artery in healthy individuals determined by phase-contrast magnetic resonance imaging2013In: Investigative Ophthalmology and Visual Science, ISSN 0146-0404, E-ISSN 1552-5783, Vol. 54, no 4, p. 2738-2745Article in journal (Refereed)
    Abstract [en]

    PURPOSE: Recent development of magnetic resonance imaging (MRI) offers new possibilities to assess ocular blood flow. This prospective study evaluates the feasibility of phase-contrast MRI (PCMRI) to measure flow rate in the ophthalmic artery (OA) and establish reference values in healthy young (HY) and elderly (HE) subjects.

    METHODS: Fifty HY subjects (28 females, 21-30 years of age) and 44 HE (23 females, 64-80 years of age) were scanned on a 3-Tesla MR system. The PCMRI sequence had a spatial resolution of 0.35 mm per pixel, with the measurement plan placed perpendicularly to the OA. Mean flow rate (Qmean), resistive index (RI), and arterial volume pulsatility of OA (ΔVmax) were measured from the flow rate curve. Accuracy of PCMRI measures was investigated using a vessel-phantom mimicking the diameter and the flow rate range of the human OA.

    RESULTS: Flow rate could be assessed in 97% of the OAs. Phantom investigations showed good agreement between the reference and PCMRI measurements with an error of <7%. No statistical difference was found in Qmean between HY and HE individuals (HY: mean ± SD = 10.37 ± 4.45 mL/min; HE: 10.81 ± 5.15 mL/min, P = 0.655). The mean of ΔVmax (HY: 18.70 ± 7.24 μL; HE: 26.27 ± 12.59 μL, P < 0.001) and RI (HY: 0.62 ± 0.08; HE: 0.67 ± 0.1, P = 0.012) were significantly different between HY and HE.

    CONCLUSIONS: This study demonstrated that the flow rate of OA can be quantified using PCMRI. There was an age difference in the pulsatility parameters; however, the mean flow rate appeared independent of age. The primary difference in flow curves between HE and HY was in the relaxation phase of the systolic peak.

    Development of heart block in children of SSA/SSB-autoantibody-positive women is associated with maternal age and displays a season-of-birth pattern2012In: Annals of the Rheumatic Diseases, ISSN 0003-4967, E-ISSN 1468-2060, Vol. 71, no 3, p. 334-340Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: Congenital heart block may develop in the fetuses of Ro/SSA-positive and La/SSB-positive mothers. Recurrence rates of only 10-20% despite persisting maternal antibodies indicate that additional factors are critical for the establishment of heart block. The authors investigated the influence of other maternal and fetal factors on heart block development in a Swedish population-based cohort.

    METHODS: The influence of fetal gender, maternal age, parity and time of birth on heart block development was analysed in 145 families, including Ro/La-positive (n=190) and Ro/La-negative (n=165) pregnancies.

    RESULTS: There was a recurrence rate of 12.1% in Ro/La-positive women, and no recurrence in Ro/La-negative women. Fetal gender and parity did not influence the development of heart block in either group. Maternal age in Ro/La-positive pregnancies with a child affected by heart block was, however, significantly higher than in pregnancies resulting in babies without heart block (p<0.05).Seasonal timing of pregnancy influenced the outcome. Gestational susceptibility weeks 18-24 occurring during January-March correlated with a higher proportion of children with heart block and lower vitamin D levels during the same period in a representative sample of Swedish women and a corresponding higher proportion of children with heart block born in the summer (p<0.02). Maternal age or seasonal timing of pregnancy did not affect the outcome in Ro/La-negative pregnancies.

    CONCLUSION: This study identifies maternal age and seasonal timing of pregnancy as novel risk factors for heart block development in children of Ro/La-positive women. These observations may be useful for counselling when pregnancy is considered.

    Therapeutic decisions in ALS patients: cross-cultural differences and clinical implications2018In: Journal of Neurology, ISSN 0340-5354, E-ISSN 1432-1459, Vol. 265, no 7, p. 1600-1606Article in journal (Refereed)
    Abstract [en]

    Objective: Quantitative analysis of decision-making on therapeutic options in different sociocultural context in amyotrophic lateral sclerosis (ALS).

    Methods: ALS patients (n = 244) were consecutively recruited in Germany (n = 83), Poland (n = 83), and Sweden (n = 78) in a prospective cross-cultural study (www.NEEDSinALS.com). They were interviewed on preferences for therapeutic techniques including invasive (IV) and non-invasive ventilation (NIV), as well as percutaneous endoscopic gastrostomy (PEG) and on hypothetical termination of these using quantitative questions. Using standardized questionnaires, religiousness, personal values, quality of life, and depressiveness were assessed.

    Results: NIV was most frequently used in Germany and PEG in Sweden. Swedish patients were most liberal on initiation and termination of PEG, NIV and IV. Polish patients were mostly undecided and were least likely to consider discontinuing supportive management. Current use was partly associated with age, gender and state of physical function; also, financial support explained some variance. Future preferences on therapeutic options from the patient’s perspective were also closely associated with cultural factors. The more oriented towards traditional and conservative values, the less likely patients were to decide for invasive therapeutic devices (IV, PEG), the least likely to have ideations to discontinue any device and the more likely to have an undecided attitude.

    Conclusions: Current use of therapeutic options is determined by medical condition in analogy to clinical guidelines. For future considerations, other factors such as cultural background are crucial, yielding hurdles to be regarded in the implementation of advanced directives in a multicultural environment.

    [New documentation routines in psychiatry in Västerbotten: unified structure for better quality of care].1999In: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 96, no 17, p. 2102-6Article in journal (Refereed)
    Abstract [sv]

    During recent decades psychiatric health care has become increasingly complex due to substantial clinical improvements and to the growing need of integrating psychiatric services with other health and welfare services in the community. The traditional psychiatric record format is incompatible both with these requirements and with the practical advantages and difficulties of modern computer technology. In a collaborative effort involving most professional categories at three psychiatric units in the county of Västerbotten in northern Sweden, a new structured format for medical records was developed. The basic feature is a structured summary of background factors, social situation, drug habits, and general health, which is reviewed and updated as necessary. The psychiatric condition is described in some detail, including onset and course, symptomatology, personality factors, diagnosis, treatment results, suicidality, etc. Day to day treatment is outlined in in- and out-patient treatment plans, which are evaluated and revised at regular intervals. The new record format, which is used by all categories of health care professionals, is intended to promote goal-directed treatment and professional collaboration, and is easily adapted to computer technology.

    Hur ska jag göra för att ingen ska märka mig?: En kvalitativ studie i offrets upplevelse av mobbning2013Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Mobbning är ett fenomen som både barn och vuxna har i sin närhet genom sina liv.

    Mobbning är orsaken till ett högt antal sjukskrivningar och självmord varje år i

    Sverige. Syftet med denna uppsats är att fördjupa förståelsen av mobbning i skolan

    och i arbetslivet/på arbetsplatser genom att utgå från tre barns/skolelevers och tre

    vuxnas upplevelser som offer. Resultatet tolkas genom en för studien skapad

    tolkningsmodell. Studien utfördes genom kvalitativa intervjuer av tre vuxna och tre

    högstadieelever. Resultatet visar att informanterna genomlev en liknande process av

    underkastelse samt psykisk och fysisk utmattning. Informanterna reagerade med

    uppgivenhet och underkastade sig mobbningens system. Under lång tid utmattades

    informanterna av mobbningen med negativ effekt på deras förmåga till gränssättning

    och självkänsla. Studiens resultat visar på att informanternas uppgivna underkastelse

    till stor del är instinktiv. Studien tar fasta på informanternas behov av socialt stöd men

    ser också hur informanterna drog sig undan social kontakt under mobbningen.

    Tolkningsmodellen som användes för studien tycktes behjälplig och skulle kunna

    användas för att enklare förstå och förmedla hur mobbningens förlopp påverkar offret.

    Platelet [3H]paroxetine binding to 5-HT uptake sites in Alzheimer's disease.1991In: Neurobiology of Aging, ISSN 0197-4580, E-ISSN 1558-1497, Vol. 12, no 5, p. 531-4Article in journal (Refereed)
    Abstract [en]

    Platelet serotonin (5-hydroxytryptamine, 5-HT) uptake sites were studied in a control group (n = 30) and an Alzheimer group (n = 40) using [3H]paroxetine as radioligand. The maximum number of binding sites (Bmax) for control (1250 +/- 60 fmol/mg protein) was not different from the Alzheimer group (1280 +/- 40 fmol/mg protein). There were no differences in apparent binding affinity (Kd): 0.046 (0.024-0.062) nM for control and 0.040 (0.027-0.061) nM for Alzheimer. Thus even though several previous studies have demonstrated marked atrophy of 5-HT containing neurites and 5-HT uptake sites in Alzheimer's disease, these findings are not found in the periphery on platelets. The platelet 5-HT uptake site cannot be used as a peripheral marker of Alzheimer's disease.

    Seasonal variations in vitamin D in relation to growth in short prepubertal children before and during first year growth hormone treatment2015In: Journal of Endocrinological Investigation, ISSN 0391-4097, E-ISSN 1720-8386, Vol. 38, no 12, p. 1309-1317Article in journal (Refereed)
    Abstract [en]

    Purpose This study investigated the relationship between seasonal variations in 25-hydroxyvitamin D (25(OH) D) levels and growth in prepubertal children during both the pretreatment year and the first year of GH treatment. Methods The study included 249 short prepubertal children with a broad range of GH secretion, GH(max) during a 24 h profile median 23; range 1-127 mU/L, 191 boys (mean age +/- SD, 8.6 +/- 2.6 years), 58 girls (7.5 +/- 1.9 years) receiving GH treatment (mean 43 mu g/kg/day; range 17-99 mu g/kg/day). Serum 25(OH) D was measured using an automated IDS-iSYS immunoassay. Results 25(OH) D levels showed seasonal variation, and decreased significantly during GH treatment. 25(OH) D levels at start and first year reduction in 25(OH) D, correlated (-) with the first year growth response during treatment. The degree of GH secretion capacity within our study population of mainly non-GH deficient children and 25(OH) D sufficient (67 +/- 29 nmol/L) had no influence on 25(OH) D levels. Growth during GH treatment were independent of seasonal variations in 25(OH) D. Multiple regression analysis showed that 25(OH) D levels at treatment start, together with auxological data and IGF-binding protein-3(SDS), explained 61 % of the variation in first year gain in height(SDS). Conclusion 25(OH) D levels were associated with first year growth response to GH and may be a useful contribution to future growth prediction models.

    Försoning i själavård och i psykoterapi2007Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Jag har valt, att i mitt uppsatsarbete undersöka försoningsprocessen i själavård och i psykoterapi. Frågeställningar som jag ville ha besvarade med denna uppsats var, hur ser försoningsprocessen ut i själavård och i psykoterapi? Vad skiljer processerna åt samt om områdena kan korsbefrukta varandra? Jag har valt litteratur som fångar upp försoningen som process. Jag har börjat med att definiera försoning som begrepp. Försoning är ett centralt begrepp inom teologin men inte inom psykoterapin. I den psykodynamiska teoridelen är barnets tidiga utveckling samt bearbetning av sorg de centrala psykologiska teman som behandlats. Jag har sedan refererat litteratur som jag har ansett viktig, med tanke på vad som särskilt behöver bearbetas på vägen mot försoning såsom avund, tacksamhet, sorg, omsorg och gottgörelse. För att få svar på mina frågeställningar har jag genomfört tre djupintervjuer enligt kvalitativ metod. Jag har intervjuat en psykoterapeut, en själavårdare samt en person som är både själavårdare och psykoterapeut.

     

    Min undersökning har visat att försoningsprocessen ser olika ut i själavård och i psykoterapi men att det också finns mycket som förenar de båda förhållningssätten. Områdena kan korsbefrukta varandra på så sätt att livsåskådningsfrågor ligger nära psykoterapeutiska frågor. Om man förenar kropp, själ och ande och ser människan som en helhet kan båda metoderna öppna upp och berika varandra. Undersökningen har visat att försoningsbegreppet är användbart i psykoterapi på grund av att processen är verksam och begreppet är neutralt och inkluderande.

    Prognostic significance of specific anti-WT1 IgG antibody level in plasma in patients with ovarian carcinoma2014In: Cancer Medicine, ISSN 2045-7634, E-ISSN 2045-7634, Vol. 3, no 4, p. 909-918Article in journal (Refereed)
    Abstract [en]

    Ovarian carcinoma (OC) has a poor prognosis and lack early effective screening markers. Wilm's tumor gene 1 (WT1) is overexpressed in OCs. Therefore, it is of great interest to investigate whether WT1-specific antibody (Ab) measurements in plasma can serve as a biomarker of anti-OC response, and is of importance in relation to patient prognosis. Peripheral blood samples were obtained from a total of 103 women with ovarian tumors with median being 1 day (range 0-48 days) before operation. WT1 IgG Ab levels were evaluated using enzyme-linked immunosorbent assay (ELISA). Immunohistochemical analysis of WT1 protein expression was performed on OC tissue samples. We found that low-WT1 Ab level in plasma was related to improved survival in patients diagnosed at stages III-IV and grade 3 carcinomas. Positive WT1 protein staining on OC tissue samples had a negative impact on survival in the entire cohort, both overall survival (OS) (P = 0.046) and progression-free survival (PFS) (P = 0.006), but not in the serous OC subtype. Combining WT1 IgG Ab levels and WT1 staining, patients with high-WT1 IgG Ab levels in plasma and positive WT1 protein staining in cancer tissues had shorter survival, with a significant association in PFS (P = 0.016). These results indicated that WT1 Ab measurements in plasma and WT1 staining in tissue specimens could be useful as biomarkers for patient outcome in the high-risk subtypes of OCs for postoperative individualized therapy.

    Acute intermittent porphyria in women: clinical expression, use and experience of exogenous sex hormones. A population-based study in northern Sweden2003In: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 254, no 2, p. 176-183Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To describe the clinical expression of acute intermittent porphyria (AIP) in women, their use of exogenous sex hormones, and the effects on AIP. DESIGN: A retrospective population-based study. SUBJECTS: All women aged > or =18 years (n = 190) with DNA-diagnosed AIP in northern Sweden. RESULTS: A total of 166 women (87%) participated; 91 (55%) had manifest AIP. Severe attacks were reported by 82%; 39% reported recurrent premenstrual AIP attacks and 22% reported chronic AIP symptoms. Oral hormonal contraceptives had been used by 58% of all these women and by 50 with manifest AIP (57%). Twelve women (24%) associated oral contraceptives as precipitating AIP attacks; in nine cases their first attack. One woman experienced relief from AIP symptoms. On commencing their treatment, 72% of the women with manifest AIP had not yet suffered their first attack. Twenty-two women (25%) aged > or =45 years had used hormonal replacement therapy (HRT) at menopause to remedy climacteric symptoms (the percutaneous route was most frequently used); no AIP attack was precipitated. HRT to remedy vaginal dryness was used by 26 women (28%) aged > or =45 years without triggering an AIP attack. Miscarriages were more frequent in women with manifest AIP (50%) than in the latent group (30%, P = 0.014). CONCLUSIONS: About half of the women with AIP had used oral hormonal contraceptives. As 25% of women with manifest AIP reported attacks associated with such drugs, caution must still be recommended. Menopausal HRT only rarely affected the disorder. Miscarriage was more common amongst women with manifest AIP.

    Bile salt-stimulated lipase and pancreatic lipase-related protein 2: key enzymes for lipid digestion in the newborn examined using the Caco-2 cell line2011In: Journal of Lipid Research, ISSN 0022-2275, E-ISSN 1539-7262, Vol. 52, no 11, p. 1949-1956Article in journal (Refereed)
    Abstract [en]

    In rodents, bile salt-stimulated lipase (BSSL) and pancreatic lipase-related protein 2 (PLRP2) are the dominant lipases expressed in the exocrine pancreas in early life, when milk is the main food. The aim of the present study was to evaluate if BSSL and PLRP2 are also key enzymes in neonatal intestinal fat digestion. Using Caco-2 cells as a model for the small intestinal epithelium, purified human enzymes were incubated in the apical chamber with substrates and bile salt concentrations resembling the milieu of the small intestine of newborn infants. BSSL and PLRP2 hydrolyzed triglycerides (TG) to free fatty acids (FA) and glycerol. The cells took up the FA, which were reesterfied to TG. Together, BSSL and PLRP2 have a synergistic effect, increasing cellular uptake 4-fold compared to the sum of each lipase alone. A synergistic effect was also observed with retinyl ester as a substrate. PLRP2 hydrolyzed cholesteryl ester but not as efficiently as BSSL, and the two had an additive rather than synergistic effect. We conclude the key enzymes in intestinal fat digestion are different in newborns than later in life. Further studies are needed to fully understand this difference and its implication for designing optimal neonatal nutrition.

    Brist på sympati: Psykoterapeuters upplevelser och erfarenheterav att arbeta med klienterde inte känner sympati inför2016Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning Studiens syfte var att undersöka terapeuters erfarenheter av hur ett samarbete kan skapas när utgångspunkten är att man inte känner sympati för patienten i en terapirelation. Det finns förhållandevis lite forskning som handlar om denna specifika aspekt av behandlingsrelationen. För att belysa frågan intervjuades sju legitimerade psykoterapeuter med en halvstrukturerad fokuserad intervju. Nyckelord och citat utmynnade i fem huvudteman med underteman. Huvudteman var: Utforskande/Nyfikenhet, Allians, Arbetsmetoder, Värderingar och Egen utveckling. Informanterna menade att det går att ha en samarbetsrelation med en patient trots att man som terapeut inte känner sympati men man upplever alliansen som svagare. De upplevde att det underlättar att ha en god terapeutisk allians över tid och att utfallet blir mer gynnsamt. Vi fann också att terapeutens personliga värderingar och etiska principer är det som avgör om man kan ha en behandlingsrelation överhuvudtaget. Hamnar terapeuten i alltför svåra personliga värdekonflikter upplevde samtliga att det inte gick att fortsätta. Resultatet visar att brist på sympati för patienter förekommer och intervjupersonerna hade metoder för att hantera dessa känslor. Lång yrkeserfarenhet, livserfarenhet, egenterapi, utbildning, handledning och tillgång till kolleger kan ha varit underlättande i hanteringen av de problem i terapirelation och behandling som en bristande sympati kan skapa.   Nyckelord: Allians, Sympati, Metod, Psykoterapi, Antipati

    Nationella bedömningsstödet i läsutveckling för årskurs 1: Ett värdefullt verktyg för pedagoger?2019Independent thesis Advanced level (degree of Master (One Year)), 240 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund 

    I svensk skola är ett av målenatt tidigt identifiera elever med nedsatt läsförmåga. För att underlätta identifieringen har ett nationellt bedömningsstöd arbetats fram. Nedsatt läsförståelse beror på nedsatt avkodningsförmåga eller nedsatt språkförståelse. Svårigheter med avkodning respektive språkförståelse kräver olika insatser i skolan.  

    Syfte 

    Syftet med studien var att undersöka om nationella bedömningsstödet för läsutvecklingi årskurs 1 identifierar andraelever änstandardiserade och normerade screeningtest genomfördai årskurs 2. Syftet var vidareatt undersöka om de elever som identifierats med nedsatt läsförmåga på nationella bedömningsstödet även uppvisar språkliga svårigheter samt hur pedagogerna använder resultatet på nationella bedömningsstödet för planering av vidare insatser. 

    Metod

    Studien omfattade 41 elever i årskurs 2 som genomfört nationella bedömningsstödet i årskurs 1 och DLS läsförståelse i årskurs 2. Eleverna testades med avkodningstesten Vilket är rätt?och Vilket låter rätt?och språkförståelsetestet TROG-2.Studien inkluderade även en intervju med 4 pedagoger som har ansvar för genomförandet av nationella bedömningsstödet.

    Resultat

    Nationella bedömningsstödet identifierade 13 elever med nedsatt läsförmåga i årskurs 1, screeningtesten DLS läsförståelseVilket är rätt?och Vilket låter rätt?identifierade 16 elever i årskurs 2. Screeningtesten identifierade 7 elever (44%) som inte identifierats på nationella bedömningsstödet. Nationella bedömningsstödet identifierade 2 elever med nedsatt språkförståelse. Samtliga pedagoger använder resultatet från nationella bedömningsstödet för planering av insatser. 

    Slutsatser

    Nationella bedömningsstödet fungerar till viss del i skolor där det utförs av pedagoger som är utbildade i nationella bedömningsstödet. Däremot identifierar nationella bedömningsstödet färre elever än standardiserade och normerade screeningtest och är mer tidskrävande.

    Familjeterapi i socialtjänsten2005Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet är att beskriva familjeterapin och dess framväxt samt undersöka vilka förutsättningar det finns för att bedriva familjeterapi i socialtjänsten. Sju intervjuer gjordes med företrädare för olika familjebehandlingsteam om organisation, verksamhet, metod, utbildning och utvärdering. Teoretiska utgångspunkter är familjeterapins historia och metoder, forskning om familjeterapeutiska metoder och vad som är verksamt i terapi. Resultatet visar att det familjeterapeutiska arbetet huvudsakligen utförs av socionomer med psykoterapeutisk vidareutbildning. Arbetet bedrivs oftast på uppdrag av socialsekreterare i samarbete med familjen. Eklektiska, språksystemiska och manualbaserade metoder används. Slutsatsen är att valet av metoder är av underordnad betydelse, evidens- och manualbaserade metoder är inte bättre än andra. Socialtjänsten behöver en mångfald av metoder så att behandlarna kan välja de som passar bäst. Viktigast är att tillvarata det som händer i familjens liv och satsa på allt som främjar en god allians. Då är sannolikheten störst för ett lyckat behandlingsresultat.

    Road traffic noise, air pollution, and risk of dementia: results from the Betula project2018In: Environmental Research, ISSN 0013-9351, E-ISSN 1096-0953, Vol. 166, p. 334-339Article in journal (Refereed)
    Abstract [en]

    Background: There is growing evidence for a negative impact of traffic-related air pollution on risk of dementia. However, the contribution of noise exposure to this association has been rarely examined.

    Objective: We aimed to investigate the individual and combined effect of noise and air pollution on risk of dementia.

    Methods: Data on dementia incidence over a 15 year period was obtained from the Betula project, a longitudinal study on health and ageing. Estimates of annual mean levels of nitrogen oxides (NOx) at the participants’ residential address were obtained using a land-use regression model. Modelled data provided road traffic noise levels (Leq. 24 h) at the participants’ residential address at baseline. Cox proportional hazard regression was used to calculate hazard ratios (HR).

    Results: Of 1721 participants at baseline, 302 developed dementia during the follow up period. Exposure to noise levels (Leq. 24 h) > 55 dB had no significant effect on dementia risk (HR 0.95; CI: 0.57, 1.57). Residing in the two highest quartiles of NOx exposure was associated with an increased risk of dementia. The risk associated with NOx was not modified by adjusting for noise. Moreover, we found no significant interaction effects between NOx and road traffic noise on dementia risk.

    Conclusion: We found no evidence that exposure to road traffic noise, either independently or in combination with traffic air pollution, was associated with risk of dementia in our study area. Our results suggest that pollution should be considered the main component in the association between traffic related exposures and dementia.

    Narrativ förmåga i återberättande hos elever med svag textförståelse i åk 22017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background. Much of children’s spontaneous communication is in the form of storytelling. By examining micro- and macrostructures in retelling, different aspects of linguistic ability can be mapped. Children with poor text comprehension show weakness in many linguistic areas and an appropriate analysis can serve as a basis for identifying individuals who need support, as well as guidance for intervention.

    Aim. The first part of this study investigates micro- and macrostructural differences in narrative retelling between students with and without poor text comprehension. The second part investigates narrative retelling by students identified with poor narrative quality.

    Methods. In the first part of the study, retellings from second grade students were analyzed at micro- and macrostructural levels. In the second part, a qualitative analysis of the retellings based on these levels was performed.

    Results. In part 1, no significant differences between the groups were observed. However, students with poor text comprehension tended to have a higher linguistic productivity in their retellings and students with good text comprehension had more complex structures. Part 2, it was found that the students with poor narrative quality tended to summarize the story and exclude parts.

    Conclusions. Students with language difficulties are not a homogeneous group. Hence, an intervention needs to be adapted to the needs of the student. Further, the results indicate that a short intervention has the potential to equalize possible differences in narrative retelling between students with and without poor text comprehension.

    Implications of psychiatric disorders during pregnancy and the postpartum period - A population-based study2004Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Depressive and anxiety disorders are common health problems, affecting women at least twice as often as men. Although some studies have been made on pregnant women or, especially, in the postpartum period, most of these studies have been performed on small samples, mainly specific risk groups such as teenage mothers, women of low socioeconomic status and certain ethnic groups. Also, there is a lack of studies on antenatal and postpartum depression and/or anxiety using diagnostic criteria adhering to the Diagnostic and Statistical Manual of Mental disorders, fourth edition (DSM-IV).

    Aims and methods: The aims were to estimate the point prevalence of mood, anxiety and eating disorders, based on DSM-IV criteria, in an unselected population during the second trimester of pregnancy, and to assess the obstetric and neonatal outcome, as well as the health care consumption during pregnancy, delivery and the early postpartum period among women with a psychiatric disorder, compared to healthy subjects. Finally, we aimed to investigate depression and anxiety, and associated maternal characteristics and events through pregnancy and the postpartum period in the same group of women. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used for assessment of psychiatric disorders during the second trimester of pregnancy and three to six months after delivery. From October 2nd, 2000, to October 1st, 2001 all women attending the second trimester routine ultrasound-screening at two different hospitals in northern Sweden (at Umeå University Hospital and at Sunderby Central Hospital) were approached for participation in the study. After delivery, data were extracted from the medical records of the mothers and their offspring to evaluate obstetric and neonatal outcome. Three to six months after delivery, the women who had an antenatal depression and/or anxiety were contacted for an assessment using the PRIME-MD. The same procedure was made in a control group, consisting of 500 women, randomly selected among those who did not have any psychiatric diagnosis according to the PRIME-MD investigation during the second trimester of pregnancy.

    Results and conclusions: Of the 1555 women in the study population, 220 (14.1%) had one or more PRIME-MD diagnoses. Living single, low socioeconomic status, smoking, multiparity and a body mass index of 30 or more were significantly associated with a psychiatric diagnosis in the second trimester of pregnancy. Women with antenatal depression and/or anxiety more often suffered from nausea and vomiting during pregnancy were more often on sick leave, and they visited their obstetrician more often than healthy subjects, specifically because of fear of childbirth and premature contractions. Also, they were more commonly delivered by elective caesarean section, had an increased use of epidural analgesia and reported a longer self-experienced duration of labor. Severe complications of pregnancy, delivery, and the early postpartum period were not affected by antenatal depression and/or anxiety. There was no significant difference in neonatal outcome depending on antenatal depressive or anxiety disorder. Fewer cases of depressive and/or anxiety disorders were prevalent postpartum, but there was a significant shift from a majority of sub-threshold diagnoses during pregnancy to full DSM-IV diagnoses during the postpartum period. Previous psychiatric disorder and living singly were significantly associated with both a new-onset and a postpartum continuation/recurrence of depression and/or anxiety. Postpartum continuation/recurrence of a psychiatric disorder was additionally associated with smoking, obesity, and adverse obstetric events.

    Point prevalence of psychiatric disorders during the second trimester of pregnancy: a population-based study.2003In: American Journal of Obstetrics and Gynecology, ISSN 0002-9378, E-ISSN 1097-6868, Vol. 189, no 1, p. 148-154Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: This study was undertaken to determine the point prevalence of psychiatric disorders during the second trimester of pregnancy in a population-based sample of pregnant women. STUDY DESIGN: Participants were 1795 consecutive pregnant women attending routine ultrasound screening at two obstetric clinics in Northern Sweden during 1 year. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used for evaluating. RESULTS: Overall, 1734 (96.6%) of the women filled in the PRIME-MD patient questionnaire. Psychiatric disorders were present in 14.1% of the women. Major depression was prevalent in 3.3% of patients and minor depression in 6.9% of patients. Anxiety disorders were encountered in 6.6% of patients. Women with psychiatric disorders displayed significantly more somatic symptoms and more pronounced fear of childbirth. Among diagnosed patients, only 5.5% had some form of treatment. CONCLUSION: The prevalence of mood and anxiety disorders in this unselected population of pregnant women was high and the majority of the women were found to be undiagnosed and untreated.

    Depression and anxiety during pregnancy and six months postpartum: a follow-up study2006In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 85, no 8, p. 937-944Article in journal (Refereed)
    Abstract [en]

    AIMS: To investigate the relationship between antenatal and postpartum depression and anxiety and to explore associated maternal characteristics. METHODS: From a population-based sample of 1,555 women attending two obstetric clinics in Sweden, all women with an antenatal psychiatric diagnosis (n = 220) and a random selection of healthy women (n = 500) were contacted for a second assessment three to six months postpartum. The Primary Care Evaluation of Mental Disorders was used for evaluation on both occasions. RESULTS: Fewer cases of depressive and/or anxiety disorders were prevalent postpartum compared with the second trimester screening. Depression and/or anxiety were prevalent in 16.5% of postpartal women versus 29.2% of pregnant women. There was a significant shift from a majority of subthreshold diagnoses during pregnancy to full Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) diagnoses during the postpartum period. A history of previous psychiatric disorder, living single, and obesity were significantly associated with a new-onset postpartum psychiatric disorder. The absence of a previous psychiatric disorder was significantly associated with a postpartum recovery of depression or anxiety. CONCLUSIONS: Depression and anxiety appear to be less common postpartum than during pregnancy.

    Abstract [en]

    OBJECTIVE: To investigate the obstetric outcome and health care consumption during pregnancy, delivery, and the early postpartum period in an unselected population-based sample of pregnant women diagnosed with antenatal depressive and/or anxiety disorders, compared with healthy subjects. METHODS: Participants were 1,495 women attending 2 obstetric clinics in Northern Sweden. The Primary Care Evaluation of Mental Disorders was used to evaluate depressive and anxiety disorders in the second trimester of pregnancy. To assess demographic characteristics, obstetric outcome, and complications, the medical records of the included women were reviewed. RESULTS: Significant associations were found between depression and/or anxiety and increased nausea and vomiting, prolonged sick leave during pregnancy and increased number of visits to the obstetrician, specifically, visits related to fear of childbirth and those related to contractions. Planned cesarean delivery and epidural analgesia during labor were also significantly more common in women with antenatal depression and/or anxiety. CONCLUSION: There is an association between antenatal depressive and/or anxiety disorders and increased health care use (including cesarean deliveries) during pregnancy and delivery.

    Neonatal outcome following maternal antenatal depression and anxiety: a population-based study.2004In: American Journal of Epidemiology, ISSN 0002-9262, E-ISSN 1476-6256, Vol. 159, no 9, p. 872-881Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to determine neonatal outcomes among women who had depressive and anxiety disorders during the second trimester of pregnancy in a population-based sample. Participants were 1,465 women and their neonates born at two obstetric clinics in Sweden. The inclusion period for the women was October 2, 2000-October 1, 2001. The Primary Care Evaluation of Mental Disorders (PRIME-MD) classification system was used to evaluate mental disorders in the second trimester of pregnancy. For assessment of demographic characteristics, birth statistics, and birth-related complications, the medical records of the included women and their offspring were reviewed after delivery. The study results revealed no differences in neonatal outcome between women with antenatal depressive disorders and/or anxiety disorders and healthy subjects. The authors conclude that neonatal outcome did not deteriorate despite the women's impaired mental health during pregnancy.

    Verksamhetsförlagd utbildnings påverkan på rösten: hos förskollärarstudenter2018Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Förskollärare är högt representerade bland patienter med röststörning på logoped-mottagningar vilket kan kopplas till långvarigt röstanvändande och belastande omgivningsfaktorer. Redan under utbildningen börjar röstbesvär uppkomma hos många studenter och detta verkar öka i samband med deras verksamhetsförlagda utbildning (VFU).

     

    Syfte

    Syftet med studien var att undersöka om förskollärarstudenters röster påverkas av VFU. Studien undersökte även förekomst av individuella och arbetsmiljömässiga riskfaktorer för röstbesvär.   

     

    Metod

    Studien omfattade 11 förskollärarstudenter som läste termin 5 på Lärarhögskolan och genomförde VFU under vårterminen 2018. En inspelning samt självskattning av deras röster gjordes före och efter VFU. Inspelningarna bedömdes perceptuellt och jämfördes tillsammans med självskattningarna. Individuella och arbetsmiljömässiga faktorer samlades in genom frågeformulär.

     

    Resultat

    Denna studie visade att det fanns en signifikant skillnad i hur deltagarna skattade sina kroppsliga röstbesvär före och efter VFU. För de perceptuella bedömningarna fanns inga signifikanta skillnader men det bedömdes att skrovlighet i rösten uppkom hos 18% av deltagarna efter VFU. Samtliga deltagare rapporterade hög ljudvolym och 73% rapporterade torr luftkvalité.

     

    Slutsats

    Studiens resultat visade att uppkomst av skrovel kan förekomma efter genomförd VFU och att brist på kunskap om rösten kan vara orsaken till detta. Förskollärarutbildningar bör ha obligatorisk röstundervisning för att förebygga röstbesvär hos framtida förskollärare.

    Frames for choice and market characteristics - a Swedish case study of community mental health services in change2015In: Nordic Social Work Research, ISSN 2156-857X, E-ISSN 2156-8588, Vol. 5, no 3, p. 227-243, article id 1059772Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to describe and analyse structural frames for choice, as well as characteristics of a free-choice market, implemented in community mental health services in Sweden. Day centres were focused. A case study was conducted. Documents were collected and semi-structured interviews were conducted with twenty-eight agents involved in the implementation process. Content analysis of data showed that users’ freedom of choice was influenced by detailed regulation. Freedom of choice was extended, but it was also substantially reduced. The gain or loss of freedom of choice depended on which aspects of the system were emphasised. Features, which could be interpreted as paternalistic, were once again structurally embedded, despite a system addressing individual freedom of choice. Further, the market did not seem to be adjusted for the average user of community mental health services.

    Freedom of choice or cost efficiency?: the implementation of a free-choice market system in community mental health services in Sweden2016In: Scandinavian Journal of Disability Research, ISSN 1501-7419, E-ISSN 1745-3011, Vol. 18, no 2, p. 129-141Article in journal (Refereed)
    Abstract [en]

    This case study investigates the implementation of a free-choice market system in community mental health services using the example of day centres for people with psychiatric disabilities. It was conducted in a major city that was about to implement a free-choice market system due to a new legislation that made it feasible. Eighteen semi-structured interviews were conducted. Agents situated in different parts of the organization were interviewed one year before and two years after the free-choice system was launched in 2010. Data showed a top–down political process. A majority of the intentions of the legislation advocated individual autonomy as the market system's main purpose; only one concerned organizational efficiency. Data reflected, however, that financial efficiency dominated the agents' experiences of the implemented system. The twofold market purpose was clearly reflected in the interviews. Front-line staff hoped for improvements mainly for the users, whereas managers mainly focused on the market as a resource allocator.

    Abstract [en]

    Marketization in community mental health services is a new phenomenon and might be the most comprehensive reform in the field since the deinstitutionalisation that occurred during the second half of the twentieth century. Historically, mental health services have been characterized by discipline and paternalistic practices.There has been an absence ofwhat is now, due to the new organizational model based on individual freedom of choice, is to be introduced.

     

    The aim of this study was to investigate the implementation of a free-choice market system in community mental health services, using the example of day centres for people with psychiatric disabilities. The study was conducted in a major city that was about to implement a free-choice market system due to a new legislation.

     

    Eighteen semi-structured interviews were conducted. Agents situated in different parts of the organization were interviewed one year before and two years after the free-choice system was launched in 2010. Data showed a top-down political process. The policy intentions of the new Act were in focus when studying the relation between policy and practice during the implementation process. A majority of the policy intentions of the new Act advocated individual autonomy as the market system’s main purpose, only one intention concerned organizational efficiency. Interview data reflected, however, that financial efficiency dominated the agents’ experiences of the implemented system. The twofold market purpose was clearly reflected in the interviews. Front-line staff hoped for improvements mainly for the users, when managers mainly focused on the market as a resource allocator.

    Testning med BeSS på svenska gymnasieungdomar utan kända språkliga svårigheter: - ett referensmaterial för bedömning av subtila språkstörningar2013Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: The test material BeSS was developed to assess subtle language difficulties in people with neurodegenerative diseases. The test has also been used in dyslexia evaluations since subtle language difficulties also can occur with dyslexia. The material lacks reference material for several age groups which is needed to give safer assessments with the material.

     

    Aim: To collect reference material for the BeSS test for high school students. To see if there is differences in performance between the test sections and if there is a gender difference.

     

    Method: The study had 28 participants, 16 girls and 12 boys, who were tested individually with BeSS. The participants did not have any known language difficulties or reading/writing problems and they were required to have attended a Swedish class with Swedish education in Swedish for at least 8 years.

     

    Results: For each of the test sections means and standard deviations are presented. For the individual test sections the students performed as follows: Repetition of long sentences mean 20.8 (SD 4.6), Sentence construction 27.3 (SD 2.3), Inference 25.5 (SD 3.5), Understanding of grammatically logical sentences 25.2 (SD 3.4), Ambiguities 22.1 (SD 5.0), Understanding of metaphors 25.5 (SD 3.9) and Definitions of words 25.6 (SD 3.2). There was not a significant gender difference.

     

    Conclusions: This study presents results for 28 students which is the beginning of a reference material that is needed for the continued use of the test in clinical speech and language pathology work. In the test sections Repetition of long sentences and Sentence construction the students performed the lowest and the highest scores. There was not a significant gender difference.

    Effect of Delayed vs Early Umbilical Cord Clamping on Iron Status and Neurodevelopment at Age 12 Months A Randomized Clinical Trial2014In: JAMA Pediatrics, ISSN 2168-6203, Vol. 168, no 6, p. 547-554Article in journal (Refereed)
    Abstract [en]

    IMPORTANCE Prevention of iron deficiency in infancy may promote neurodevelopment. Delayed cord clamping (DCC) can prevent iron deficiency during the first 6 months of life. However, no data are available on long-term effects on infant outcomes in relation to time for umbilical cord clamping. OBJECTIVE To investigate effects of DCC, as compared with early cord clamping (ECC), on infant iron status and neurodevelopment at age 12 months in a European setting. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial of 382 full-term infants born after a low-risk pregnancy at a Swedish county hospital. Follow-up at 12 months included evaluation of iron status (ferritin level, transferrin saturation, transferrin receptor level, reticulocyte hemoglobin level, and mean cell volume) and parental assessment of neurodevelopment by the Ages and Stages Questionnaire, second edition (ASQ). INTERVENTIONS Infants were randomized to DCC (>= 180 seconds after delivery) or ECC (<= 10 seconds after delivery). MAIN OUTCOMES AND MEASURES The main outcome was iron status at age 12 months; the secondary outcome was ASQ score. RESULTS In total, 347 of 382 infants (90.8%) were assessed. The DCC and ECC groups did not differ in iron status (mean ferritin level, 35.4 vs 33.6 ng/mL, respectively; P =.40) or neurodevelopment (mean ASQ total score, 229.6 vs 233.1, respectively; P =.42) at age 12 months. Predictors of ferritin levels were infant sex and ferritin in umbilical cord blood. Predictors of ASQ score were infant sex and breastfeeding within 1 hour after birth. For both outcomes, being a boy was associated with lower results. Interaction analysis showed that DCC was associated with an ASQ score 5 points higher among boys (mean [SD] score, 229 [43] for DCC vs 224 [39] for ECC) but 12 points lower among girls (mean [SD] score, 230 [39] for DCC vs 242 [36] for ECC), out of a maximum of 300 points (P =.04 for the interaction term). CONCLUSIONS AND RELEVANCE Delayed cord clamping did not affect iron status or neurodevelopment at age 12 months in a selected population of healthy term-born infants. However, it may not be possible to demonstrate minor effects on neurodevelopment with the size of the study population and the chosen method for assessment. The current data indicate that sex may influence the effects on infant development after DCC in different directions. The magnitude and biological reason for this finding remain to be investigated.

    Effects of delayed cord clamping on neurodevelopment and infection at four months of age: a randomised trial2013In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 102, no 5, p. 525-531Article in journal (Refereed)
    Abstract [en]

    Aim To investigate the effect that delayed and early umbilical cord clamping have on neurodevelopment, immunoglobulin G (IgG) and symptoms of infection during the first 4months of life.

    Methods Full-term infants (n=382) were randomised to delayed (180sec) or early cord clamping (10sec). The Ages and Stages Questionnaire (ASQ) was used to assess neurodevelopment at 4months. Immunoglobulin G was measured at birth, 23days and 4months. Parents recorded any symptoms indicating infection during the first 4months of life.

    Results The total scores from the ASQ did not differ between groups. However, the delayed cord clamping (DCC) group had a higher mean (SD) score in the problem-solving domain [55.3 (7.2) vs. 53.5 (8.2), p=0.03] at 4months and a lower mean (SD) score in the personal-social domain [49.5 (9.3) vs. 51.8 (8.1), p=0.01]. The IgG level was higher in the DCC group at 23days (11.7 vs. 11.0g/L, p=0.004), but did not differ between the groups at 4months. Symptoms of infection were comparable between the groups.

    Conclusion Delayed cord clamping did not affect overall neurodevelopment or symptoms of infection up to 4months of age, but may have an impact on specific neurodevelopmental domains.

    Effects of delayed compared with early umbilical cord clamping on maternal postpartum hemorrhage and cord blood gas sampling: a randomized trial2013In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 92, no 5, p. 567-574Article in journal (Refereed)
    Abstract [en]

    Objective. To investigate the effect of delayed cord clamping (DCC) compared with early cord clamping (ECC) on maternal postpartum hemorrhage (PPH) and umbilical cord blood gas sampling. Design. Secondary analysis of a parallel-group, single-center, randomized controlled trial. Setting. Swedish county hospital. Population. 382 term deliveries after a low-risk pregnancy. Methods. Deliveries were randomized to DCC (>= 180 seconds, n = 193) or ECC (<= 10 seconds, n = 189). Maternal blood loss was estimated by the midwife. Samples for blood gas analysis were taken from one umbilical artery and the umbilical vein, from the pulsating unclamped cord in the DCC group and from the double-clamped cord in the ECC group. Samples were classified as valid when the arterial-venous difference was -0.02 or less for pH and 0.5 kPa or more for pCO(2). Main outcome measures. PPH and proportion of valid blood gas samples. Results. The differences between the DCC and ECC groups with regard to PPH(1.2%, p = 0.8) and severe PPH(-2.7%, p = 0.3) were small and non-significant. The proportion of valid blood gas samples was similar between theDCC (67%, n = 130) and ECC (74%, n = 139) groups, with 6% (95% confidence interval: -4%-16%, p = 0.2) fewer valid samples after DCC. Conclusions. Delayed cord clamping, compared with early, did not have a significant effect on maternal postpartum hemorrhage or on the proportion of valid blood gas samples. We conclude that delayed cord clamping is a feasible method from an obstetric perspective.

    Elective caesarean: does delay in cord clamping for 30 s ensure sufficient iron stores at 4 months of age? A historical cohort control study2016In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 6, no 11, article id e012995Article in journal (Refereed)
    Abstract [en]

    Objective: To compare iron stores in infants born after elective caesarean section (CS) and a 30 s delay of umbilical cord clamping with those born vaginally after early (<= 10 s) or delayed (>= 180 s) cord clamping. Design: Prospective observational study with historical control. Setting: Swedish county hospital. Population: 64 infants born after elective CS were compared with a historical control of 166 early clamped and 168 delayed clamped after vaginal birth. Methods: Blood and iron status were measured in blood samples collected at birth, 48-96 hours after birth, 4 and 12 months of age. Primary and secondary outcome measures: Ferritin at 4 months of age was the primary outcome, second outcome measures were other indicators of iron status, and haemoglobin, at 4 and 12 months of age, as well as respiratory distress at 1 and 6 hours after birth. Results: At 4 months infants born by elective CS had better iron status than those born vaginally subjected to early cord clamping, shown by higher adjusted mean difference of ferritin concentration (39 mu g/L (95% CI 10 to 60)) and mean cell volume (1.8 fL (95% CI 0.6 to 3.0)); and lower levels of transferrin receptors (-0.39 mg/L (95% CI -0.69 to -0.08)). No differences were seen between infants born after elective CS and delayed clamped vaginally born infants at 4 months. No differences were found between groups at 12 months of age. Conclusions: Waiting to clamp the umbilical cord for 30 s after elective CS results in higher iron stores at 4 months of age compared with early cord clamping after vaginal birth, and seems to ensure iron status comparable with those achieved after 180 s delayed cord clamping after vaginal birth.

    Effect of delayed versus early umbilical cord clamping on neonatal outcomes and iron status at 4 months: a randomised controlled trial2011In: BMJ. British Medical Journal (International Ed.), ISSN 0959-8146, E-ISSN 0959-535X, Vol. 343, p. d7157-Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To investigate the effects of delayed umbilical cord clamping, compared with early clamping, on infant iron status at 4 months of age in a European setting.

    DESIGN: Randomised controlled trial.

    SETTING: Swedish county hospital.

    PARTICIPANTS: 400 full term infants born after a low risk pregnancy.

    INTERVENTION: Infants were randomised to delayed umbilical cord clamping (≥180 seconds after delivery) or early clamping (≤10 seconds after delivery).

    MAIN OUTCOME MEASURES: Haemoglobin and iron status at 4 months of age with the power estimate based on serum ferritin levels. Secondary outcomes included neonatal anaemia, early respiratory symptoms, polycythaemia, and need for phototherapy.

    RESULTS: At 4 months of age, infants showed no significant differences in haemoglobin concentration between the groups, but infants subjected to delayed cord clamping had 45% (95% confidence interval 23% to 71%) higher mean ferritin concentration (117 μg/L v 81 μg/L, P<0.001) and a lower prevalence of iron deficiency (1 (0.6%) v 10 (5.7%), P=0.01, relative risk reduction 0.90; number needed to treat=20 (17 to 67)). As for secondary outcomes, the delayed cord clamping group had lower prevalence of neonatal anaemia at 2 days of age (2 (1.2%) v 10 (6.3%), P=0.02, relative risk reduction 0.80, number needed to treat 20 (15 to 111)). There were no significant differences between groups in postnatal respiratory symptoms, polycythaemia, or hyperbilirubinaemia requiring phototherapy.

    CONCLUSIONS: Delayed cord clamping, compared with early clamping, resulted in improved iron status and reduced prevalence of iron deficiency at 4 months of age, and reduced prevalence of neonatal anaemia, without demonstrable adverse effects. As iron deficiency in infants even without anaemia has been associated with impaired development, delayed cord clamping seems to benefit full term infants even in regions with a relatively low prevalence of iron deficiency anaemia. Trial registration Clinical Trials NCT01245296.

    Abstract [en]

    IMPORTANCE Prevention of iron deficiency in infancy may promote neurodevelopment. Delayuci umbilical cord clamping (CC) prevents iron deficiency at 4 to 6 months of age, but long-term effects after 12 months of age have not been reported. OBJECTIVE To investigate the effects of delayed CC compared with early CC on neurodevelopment at 4 years of age. DESIGN, SETTING, AND PARTICIPANTS Follow-up of a randomized clinical trial conducted from April 16, 2008, through May 21, 2010, at a Swedish county hospital. Children who were included in the original study (n = 382) as full-term infants born after a low-risk pregnancy were invited to return for follow-up at 4 years of age. Wechsler Preschool and Primary Scale of Intelligence (WPPSI-111) and Movement Assessment Battery for Children (Movement ABC) scores (collected between April 18, 2012, and July 5, 2013) were assessed by a blinded psychologist. Between April 11, 2012, and August 13, 2013, parents recorded their child's development using the Ages and Stages Questionnaire, Third Edition (ASQ) and behavior using the Strengths and Difficulties Questionnaire. All data were analyzed by intention to treat. INTERVENTIONS Randomization to delayed CC (>= 180 seconds after delivery) or early CC (<= 10 seconds after delivery). MAIN OUTCOMES AND MEASURES The main outcome was full-scale IQ as assessed by the were development as assessed by the scales from the WPPSI-III and Movement ABC, development as recorded using the ASQ, and behavior using the Strengths and Difficulties Questionnaire. RESULTS We assessed 263 children (68.8%). No differences were found in WPPSI-III scores between groups. Delayed CC improved the adjusted mean differences (AMDs) in the ASQ personal-social (AMD, 2.8; 95% Cl, 0.8-4.7) and fine-motor (AMD, 2.1; 95% Cl, 0.2-4.0) domains and the Strengths and Difficulties Questionnaire prosocial subscale (AMD, 0.5; 95% Cl, >0.0-0.9). Fewer children in the delayed-CC group had results below the cutoff in the ASQ fine-motor domain (11.0% vs 3.7%; P =.02) and the Movement ABC bicycle-trail task (12.9% vs 3.8%; P =.02). Boys who received delayed CC had significantly higher AMDs in the WPPSI-III processing-speed quotient (AMD, 4.2; 95% Cl, 0.8-7.6; P =.02), Movement ABC bicycle-trail task (AMD, 0.8; 95% Cl, 0.1-1.5; P =.03), and fine-motor (AMD, 4.7; 95% Cl, 1.0-8.4; P =.01) and personal-social (AMD, 4.9; 95% Cl, 1.6-8.3; P =.004) domains of the ASQ. CONCLUSIONS AND RELEVANCE Delayed CC compared with early CC improved scores in the fine-motor at 4 years of age, especially in boys, indicating that optimizing the time to CC may affect neurodevelopment in a low-risk population of children born in a high-income country.

    Swedish maternal mortality in the 19th century by different definitions: previous stillbirths but not multiparity risk factor for maternal death.2000In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 79, no 8, p. 679-86Article in journal (Refereed)
    Abstract [en]

    In conclusion, this study shows that the mother's reproductive history was the most important risk factor measured for all definitions of maternal death. Grand multiparity did not increase the risk of maternal death. Maternal mortality ratio varied threefold in the study population, depending on the definition used. The high mortality ratios found in this study, only declining by the end of the century, should be interpreted as a general condition of the society since no significant differences could be perceived regarding social class, while unmarried women were more at risk.

    The impact of neonatal mortality on subsequent survival in rural Ethiopia.2002In: Annals of Tropical Paediatrics, ISSN 0272-4936, E-ISSN 1465-3281, Vol. 22, no 1, p. 25-32Article in journal (Refereed)
    Abstract [en]

    In countries where most deliveries occur at home and most available information is hospital-based, accurate information on neonatal mortality is difficult to obtain. This study was conducted in a rural community in Ethiopia that has been under monthly demographic surveillance since 1987. The analysis in this paper was based on data collected in the 1st decade (1987-96) and this database was used to calculate mortality incidence rates and analyse survival. The overall neonatal mortality rate was 27/1000 live births (95% CI 24.5-29.5). The rates in the early and late neonatal periods were 20 and 8/1000 live births, respectively (95% CIs 18.0-22.9 and 6.6-9.4). The mortality incidence rates show that, every day, three of every 1000 newborns die in their 1st week of life. Neonatal mortality accounted for 43% of infant mortality. If all neonates survived the 1st week of life, life expectancy would increase by 1 year. Increased risk of neonatal mortality was found to be associated with living in a rural lowland area, twin births and male gender. This paper also addresses the need for further identification of the complex environmental and behavioural risk factors for neonatal mortality and for instituting appropriate and affordable interventions to reduce neonatal mortality.

    Genetic variants in association studies: review of strengths and weaknesses in study design and current knowledge of impact on cancer risk2009In: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 48, no 7, p. 948-954Article in journal (Refereed)
    Abstract [en]

    Sequencing of the human genome has recently been completed and mapping of the complete genomic variation is ongoing. During the last decade there has been a huge expansion of studies of genetic variants, both with respect to association studies of disease risk and for studies of genetic factors of prognosis and treatments response, i.e., pharmacogenomics. The use of genetics to predict a patient's risk of disease or treatment response is one step toward an improved personalised prevention and screening modality for the prevention of cancer and treatment selection. The technology and statistical methods for completing whole genome tagging of variants and genome wide association studies has developed rapidly over the last decade. After identifying the genetic loci with the strongest, statistical associations with disease risk, future studies will need to further characterise the genotype-phenotype relationship to provide a biological basis for prevention and treatment decisions according to genetic profile. This review discusses some of the general issues and problems of study design; we also discuss challenges in conducting valid association studies in rare cancers such as paediatric brain tumours, where there is support for genetic susceptibility but difficulties in assembling large sample sizes. The clinical interpretation and implementation of genetic association studies with respect to disease risk and treatment is not yet well defined and remains an important area of future research.

    Pasteurization of mother's own milk reduces fat absorption and growth in preterm infants.2007In: Acta paediatrica, ISSN 0803-5253, Vol. 96, no 10, p. 1445-9Article in journal (Refereed)
    Abstract [en]

    Aim: A randomized study was conducted to evaluate whether pasteurized milk (Holder pasteurization 62.5 degrees C, 30 min) reduces fat absorption and growth in preterm infants. Methods: Preterm infants (825-1325 g) born with gestational age </=30 weeks were randomized into two groups, of which one started with pasteurized own mother's milk for 1 week and continued with raw milk the following week, and a second group was fed in reverse order. By using this design the infants served as their own controls. At the end of each week, a 72-h fat balance was performed and growth was monitored. Results: We found, on an average, 17% higher fat absorption with raw as compared to pasteurized milk. Infants gained more weight and linear growth assessed as knee-heel length was also greater during the week they were fed raw milk as compared to the week they were fed pasteurized milk. Conclusion: Feeding preterm infants pasteurized as compared to raw own mother's milk reduced fat absorption. When the infants were fed raw milk, they gained more in knee-heel length compared to when they were fed pasteurized milk.

    Formula feeding skews immune cell composition toward adaptive immunity compared to breastfeeding2009In: Journal of Immunology, ISSN 0022-1767, E-ISSN 1550-6606, Vol. 183, no 7, p. 4322-4328Article in journal (Refereed)
    Abstract [en]

    The ontogeny of the immune system and the effect thereon by type of infant feeding is incompletely understood. We analyzed frequencies and composition of immune cells in blood of breastfed (BF) and formula-fed (FF) infants at 1.5, 4, and 6 mo of age. Three formulas with the same protein concentration but with varying levels of alpha-lactalbumin and caseinoglycomacropeptide were compared. Twenty-nine exclusively BF infants served as reference, and 17 infants in each formula group completed the study. Whole blood and PBMCs were analyzed by flow cytometry and immunoflow cytometry, respectively. Leukocyte count of BF infants increased with time due to increased frequency of neutrophils. Lymphocyte count was high at 1.5 mo and was unchanged over time, as were the relative proportions of CD4+ alphabetaT cells, CD8+ alphabetaT cells, B cells, NK cells, and gammadeltaT cells. Most CD45R0+CD3+ cells were HLA-DR- and hence memory cells. Compared with breastfeeding, formula feeding resulted in a significant decrease in proportion of NK cells, but a significant increase in naive CD4+ alphabetaT cells and an elevated CD4-to-CD8 ratio, that is, 3.3 in the combined FF groups compared with 2.6 in the BF group. No significant differences were found between the three groups of FF infants. In conclusion, blood cells of lymphoid lineage did not change significantly in frequencies or composition from 1.5 to 6 mo of age in BF infants. In contrast, FF infants displayed an ongoing maturation of adaptive immunity cells and a delayed recruitment of innate immunity cells as compared with BF infants.

    Three variants of parathyroid hormone-related protein messenger RNA are expressed in human mammary gland.1997In: Pediatric Research, ISSN 0031-3998, E-ISSN 1530-0447, Vol. 41, no 3, p. 380-3Article in journal (Refereed)
    Abstract [en]

    PTH-related protein (PTHrP) is found in a variety of tissues; particularly high levels are present in human milk. The structure of the human PTHrP gene is complex, and alternative splicing allows expression of three different variants PTHrP139, PTHrP173, and PTHrP141, respectively. To determine which of the variants are expressed in human mammary gland a reverse transcriptase polymerase chain reaction (RT-PCR) method was elaborated, distinguishing the three variants. mRNA isolated from human milk cells, human mammary epithelial cells (HMEC) and human nonlactating mammary gland cells were analyzed. The RT-PCR experiments resulted in amplification of DNA fragments corresponding to all three variants for all three cell sources tested. The nucleotide sequences of the PCR fragments were determined and verified to be identical to the reported sequences. Hence, it is concluded that human mammary gland epithelial cells express three variants of PTHrP. Whether these have different physiologic effects in the mammary gland or in the breast fed infant remain to be explored.

    Lactoferrin is responsible for the fungistatic effect of human milk.2000In: Early Human Development, ISSN 0378-3782, E-ISSN 1872-6232, Vol. 59, no 2, p. 95-105Article in journal (Refereed)
    Abstract [en]

    Human milk has recognized anti-microbial effects and it has been repeatedly shown that breast-fed infants have fewer and less severe infections than formula-fed infants. While most studies have focused on anti-bacterial and anti-viral activities few have focused on the anti-fungal effect of human milk. Dermal and other infections caused by fungi are common in very low birth weight (VLBW) infants. Using a liquid culturing method and Candida albicans and Rhodotorula rubra as representative fungi, we studied the anti-fungal effect of human milk and certain human milk proteins. In vitro, human milk showed potent inhibitory effect on fungal growth. Most, if not all of this effect was caused by lactoferrin via its iron-binding capacity; increasing the iron content of the incubation medium abolished the inhibitory effect. In contrast, other human milk proteins with known or suggested anti-microbial effects rather increased fungal growth. Viability test and electron microscopy revealed that the growth inhibitory effect of human milk, i.e. mediated by lactoferrin, is fungistatic rather than fungicidal.

    Likheter eller olikheter: Märks grundutbildningen vid bedömning av psykoterapier?2010Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen är avsedd att vara ett inlägg i frågan om hur vår grundläggande yrkesidentitet präglar våra identiteter som psykoterapeuter. Den tar upp frågan om man kan urskilja identiteten hos socionomer och psykologer efter den gemensamma psykoterapeututbildningen, utifrån de svarsalternativ en grupp psykoterapeuter gör i en vinjettundersökning.

    De teoretiska ingångarna är psykologi respektive socialt arbete och centrala begrepp för de bägge professionsfälten idag.

    Resultaten har analyserats med hjälp av kvalitativ innehållsanalys och visar på en skillnad mellan de två grupperna, framförallt när det gäller begreppen kognition och empowerment.

    I diskussionen framgår att det finns en linje även i fler av resultaten, som understryker att likheterna är större än skillnaderna, men att man kan se grundutbildningens påverkan i psykologens mer intrapsykiska förhållningssätt medan  socionomen reflekterar över  faktorer som berör människans kontextuella och samhälleliga tillvaro.

    Screening and cervical cancer cure: population based cohort study2012In: BMJ. British Medical Journal, E-ISSN 1756-1833, Vol. 344, p. e900-Article in journal (Refereed)
    Abstract [en]

    Objective To determine whether detection of invasive cervical cancer by screening results in better prognosis or merely increases the lead time until death.

    Design Nationwide population based cohort study. Setting Sweden.

    Participants All 1230 women with cervical cancer diagnosed during 1999-2001 in Sweden prospectively followed up for an average of 8.5 years. Main outcome measures Cure proportions and five year relative survival ratios, stratified by screening history, mode of detection, age, histopathological type, and FIGO (International Federation of Gynecology and Obstetrics) stage.

    Results In the screening ages, the cure proportion for women with screen detected invasive cancer was 92% (95% confidence interval 75% to 98%) and for symptomatic women was 66% (62% to 70%), a statistically significant difference in cure of 26% (16% to 36%). Among symptomatic women, the cure proportion was significantly higher for those who had been screened according to recommendations (interval cancers) than among those overdue for screening: difference in cure 14% (95% confidence interval 6% to 23%). Cure proportions were similar for all histopathological types except small cell carcinomas and were closely related to FIGO stage. A significantly higher cure proportion for screen detected cancers remained after adjustment for stage at diagnosis (difference 15%, 7% to 22%).

    Conclusions Screening is associated with improved cure of cervical cancer. Confounding cannot be ruled out, but the effect was not attributable to lead time bias and was larger than what is reflected by down-staging. Evaluations of screening programmes should consider the assessment of cure proportions.

    Screening-preventable cervical cancer risks: evidence from a nationwide audit in Sweden2008In: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 100, no 9, p. 622-629Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The effectiveness of cervical cancer screening programs differs widely in different populations. The reasons for these differences are unclear. Routine and comprehensive audits have been proposed as an ethically required component of screening. We performed a nationwide audit of the effectiveness of the Swedish cervical cancer screening program.

    METHODS: We identified all invasive cervical cancer cases that were diagnosed in Sweden from January 1, 1999, through December 31, 2001, and had been reported to the Swedish Cancer Registry (n = 1230 cases). We verified the diagnoses by histopathologic rereview and matched each case subject to five (population-based) age-matched control subjects who were identified from the National Population Register. The Pap smear screening histories for case and control subjects were reviewed for a 6-year period using the National Cervical Cancer Screening Register, which contains data on essentially all relevant cytological and histological diagnoses in Sweden. Odds ratios (ORs), and their 95% confidence intervals (CIs), of cervical cancer according to screening history were calculated in conditional logistic regression models. All statistical tests were two-sided.

    RESULTS: Women who had not had a Pap smear within the recommended screening interval had higher risk of cervical cancer than women who had been screened (OR = 2.52, 95% CI = 2.19 to 2.91). This risk was similarly increased for all age groups (P(homogeneity) = .96). The risk for non-squamous cell cervical cancers (OR = 1.59, 95% CI = 1.20 to 2.11) was also increased. Women who had not had a Pap smear within the recommended screening interval had a particularly high risk of advanced cancers (OR = 4.82, 95% CI = 3.61 to 6.44). Among women who had been screened within the recommended interval, those with abnormal Pap smears had a higher risk of cervical cancer than those with normal smears (OR = 7.55, 95% CI = 5.88 to 9.69) and constituted 11.5% of all women with cervical cancer.

    CONCLUSIONS: Nonadherence to screening intervals was the major reason for cervical cancer morbidity. The screening program was equally effective for women of all ages and was also effective against non-squamous cancers.

    Facing death: physicians' difficulties and coping strategies in cancer care1994Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Even if the treatment of cancer has developed over the last decades 50% of the patients still die of their cancer. The doctor's way of dealing with his and his patient's anxiety must surely be of significance for the treatment the patient receives.

    In the first part of the thesis earlier studies of physicians' stress and ways of coping are reported. There is a lack of systematic studies which show how doctors working with cancer patients adjust to this work. The aim of this investigation is to study cancer doctors' difficulties and coping strategies. The theoretical frame of the study embraces parts of psychoanalytical theory and coping models, emphasizing that both unconscious and conscious psychological processes play their part in the coping process.

    The second, empirical part of the study includes 23 physicians strategically selected out of a population of physicians who work with institutional care and who have daily contact with adult cancer patients. The main method of data collection has been a series of recorded interviews. The focus of the interview was the physician's perception of how he reacts, thinks, talks and acts in different phases of the cancer disease. To illustrate the defence strategies of the interviewers, the projective percept-genetic test, the "Defence Mechanism Test" (DMT) is used. The "Structural Analysis of Social Behaviour" (SASB) has been used to study the doctors' self image.

    The results indicate that the stated difficulties deeply affect the doctor as a human being. The statements reflect conflicting feelings and wishes in relation to authority, conflicting feelings and wishes in relation to frightening and injuring, conflicting feelings and wishes in relation to intimacy/distance. Thirty themes of coping strategies frequently recur and they have been grouped into seven categories. Most of the doctors "seek knowledge" and support from scientific literature. The majority of them state that attempting to "solve a problem" is their main strategy. Most of the doctors "seek support " as a part of their coping strategy. An interesting observation is that the doctors to a higher extent "seek a relation" to their patients rather than to their colleagues. Almost one third use "denial of the severity of a situation" as their main strategy. All the doctors consciously or unconsciously use "diverting strategies", i.e. undertake tasks which are devoid of contact with patients, such as research and administration or other activities which allow them to avoid the patient. One third use "projective manoeuvres" but this is never a main strategy.

    In the third part of the study the credibility of the results and their pedagogical and practical implications are discussed.
