- Western Eurasia witnessed several large-scale human migrations during the Holocene1–5. Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes—mainly from the Mesolithic and Neolithic periods—from across northern and western Eurasia. These were imputed alongside published data to obtain diploid genotypes from more than 1,600 ancient humans. Our analyses revealed a ‘great divide’ genomic boundary extending from the Black Sea to the Baltic. Mesolithic hunter-gatherers were highly genetically differentiated east and west of this zone, and the effect of the neolithization was equally disparate. Large-scale ancestry shifts occurred in the west as farming was introduced, including near-total replacement of hunter-gatherers in many areas, whereas no substantial ancestry shifts happened east of the zone during the same period. Similarly, relatedness decreased in the west from the Neolithic transition onwards, whereas, east of the Urals, relatedness remained high until around 4,000 bp, consistent with the persistence of localized groups of hunter-gatherers. The boundary dissolved when Yamnaya-related ancestry spread across western Eurasia around 5,000 bp, resulting in a second major turnover that reached most parts of Europe within a 1,000-year span. The genetic origin and fate of the Yamnaya have remained elusive, but we show that hunter-gatherers from the Middle Don region contributed ancestry to them. Yamnaya groups later admixed with individuals associated with the Globular Amphora culture before expanding into Europe. Similar turnovers occurred in western Siberia, where we report new genomic data from a ‘Neolithic steppe’ cline spanning the Siberian forest steppe to Lake Baikal. These prehistoric migrations had profound and lasting effects on the genetic diversity of Eurasian populations.

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.

- Background: Progress in cancer biomarker discovery is dependent on access to high-quality biological materials and high-resolution clinical data from the same cases. To overcome current limitations, a systematic prospective longitudinal sampling of multidisciplinary clinical data, blood and tissue from cancer patients was therefore initiated in 2010 by Uppsala and Umeå Universities and involving their corresponding University Hospitals, which are referral centers for one third of the Swedish population.Material and Methods: Patients with cancer of selected types who are treated at one of the participating hospitals are eligible for inclusion. The healthcare-integrated sampling scheme encompasses clinical data, questionnaires, blood, fresh frozen and formalin-fixed paraffin-embedded tissue specimens, diagnostic slides and radiology bioimaging data.Results: In this ongoing effort, 12,265 patients with brain tumors, breast cancers, colorectal cancers, gynecological cancers, hematological malignancies, lung cancers, neuroendocrine tumors or prostate cancers have been included until the end of 2016. From the 6914 patients included during the first five years, 98% were sampled for blood at diagnosis, 83% had paraffin-embedded and 58% had fresh frozen tissues collected. For Uppsala County, 55% of all cancer patients were included in the cohort.Conclusions: Close collaboration between participating hospitals and universities enabled prospective, longitudinal biobanking of blood and tissues and collection of multidisciplinary clinical data from cancer patients in the U-CAN cohort. Here, we summarize the first five years of operations, present U-CAN as a highly valuable cohort that will contribute to enhanced cancer research and describe the procedures to access samples and data.

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.

Multi-line detection of O2 toward rho Ophiuchi A
- 2012

Ingår i: Astronomy and Astrophysics. - : EDP Sciences. - 0004-6361 .- 1432-0746. ; 541

Tidskriftsartikel (refereegranskat)abstract
- Context. Models of pure gas-phase chemistry in well-shielded regions of molecular clouds predict relatively high levels of molecular oxygen, O-2, and water, H2O. These high abundances imply high cooling rates, leading to relatively short timescales for the evolution of gravitationally unstable dense cores, forming stars and planets. Contrary to expectations, the dedicated space missions SWAS and Odin typically found only very small amounts of water vapour and essentially no O-2 in the dense star-forming interstellar medium. Aims. Only toward rho OphA did Odin detect a very weak line of O-2 at 119 GHz in a beam of size 10 arcmin. The line emission of related molecules changes on angular scales of the order of some tens of arcseconds, requiring a larger telescope aperture such as that of the Herschel Space Observatory to resolve the O-2 emission and pinpoint its origin. Methods. We use the Heterodyne Instrument for the Far Infrared (HIFI) aboard Herschel to obtain high resolution O-2 spectra toward selected positions in the rho Oph A core. These data are analysed using standard techniques for O2 excitation and compared to recent PDR-like chemical cloud models. Results. The N-J = 3(3)-1(2) line at 487.2 GHz is clearly detected toward all three observed positions in the rho Oph A core. In addition, an oversampled map of the 5(4)-3(4) transition at 773.8 GHz reveals the detection of the line in only half of the observed area. On the basis of their ratios, the temperature of the O-2 emitting gas appears to vary quite substantially, with warm gas (greater than or similar to 50 K) being adjacent to a much colder region, of temperatures lower than 30 K. Conclusions. The exploited models predict that the O-2 column densities are sensitive to the prevailing dust temperatures, but rather insensitive to the temperatures of the gas. In agreement with these models, the observationally determined O-2 column densities do not seem to depend strongly on the derived gas temperatures, but fall into the range N(O-2) = 3 to greater than or similar to 6 x 10(15) cm(-2). Beam-averaged O-2 abundances are about 5 x 10(-8) relative to H-2. Combining the HIFI data with earlier Odin observations yields a source size at 119 GHz in the range of 4 to 5 arcmin, encompassing the entire rho Oph A core. We speculate that one of the reasons for the generally very low detection rate of O-2 is the short period of time during which O-2 molecules are reasonably abundant in molecular clouds.

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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- Introduction and hypothesis: The aim of this prospective randomized multicenter study was to compare TVT (tension-free vaginal tape) with TVT-Secur in terms of efficacy and safety.Methods: We set out to enrol 280 stress incontinent women with a half time interim analysis of short-term cure and a continuous registration of adverse events. Of 133 randomized women, 126 were operated and 123 (TVT n = 62, TVT-Secur n = 61) available for 2 months follow-up.Results: No significant differences were found between groups regarding demographics or grade of incontinence. At 2 months follow-up, subjective cure rate following TVT-Secur was significantly lower than for TVT (72% and 92%, respectively, p = 0.01). Three major complications occurred in the TVT-Secur group: tape erosion into the urethra, a tape inadvertently placed inside the bladder, and an immediate postoperative bleeding from the corona mortis. No major complications occurred in the TVT group. No significant differences were found between groups regarding perioperative bleeding, hospital stay, urge symptoms, or postoperative urinary tract infections. Median time for surgery was 13 and 22 min for TVT-Secur and TVT, respectively (p < 0.0001).Conclusions: In a prospective randomized controlled study, the TVT-Secur procedure had a significantly lower subjective cure rate than the retropubic TVT procedure. Due to this, in addition to three serious complications in the TVT-Secur group, we decided to stop further enrolment after the interim analysis. We discourage from further use of the TVT-Secur.

- INTRODUCTION AND HYPOTHESIS: The aim of this prospective randomized multicenter study was to compare retropubic tension-free vaginal tape (TVT) with TVT Secur in terms of efficacy and safety. METHODS: We set out to enrol 280 stress urinary incontinent (SUI) women with a half-time interim analysis of short-term cure and adverse events. The short-term results have previously been published. Of the133 randomized women, 125 underwent surgery, and 121 (TVT n = 61, TVT Secur n = 60) were available for follow-up 1 year postsurgery. RESULTS: No significant differences were found between groups regarding demographics or incontinence grade. One year after surgery, both subjective and objective cure rates were significantly lower for TVT Secur than for TVT (subjective cure: TVT 98 %, TVT Secur 80 %, p = 0.03; objective cure: TVT 94 %, TVT Secur 71 % for cough test, p = 0.01; TVT 76 %, TVT Secur 58 % for pad test, p = 0.05 ). Three major complications occurred in the TVT Secur group: one tape erosion into the urethra, one tape inadvertently placed into the bladder, and one immediate postoperative bleeding due to injury to the corona mortis. No major complications occurred in the TVT group. No significant differences were found between groups regarding peroperative bleeding, hospital stay, urge symptoms, residual urinary volume, subjective bladder emptying problems, postoperative urinary tract infections, and minor complications. The TVT Secur group used more antimuscarine medication after surgery than the TVT group (p = 0.03). Median time for surgery was 13 and 22 min for TVT Secur and TVT, respectively (p < 0.0001). CONCLUSION: The TVT Secur procedure had significantly inferior subjective and objective cure rates compared with the retropubic TVT procedure. Three serious adverse events occurred in the TVT Secur group. We therefore discourage further use of TVT Secur.

Influence of trophic status on PCB distribution in lake sediments and biota
- 2001

Ingår i: Environmental Pollution. - 0269-7491. ; 113:2, s. 199-210

Tidskriftsartikel (refereegranskat)abstract
- We investigated the relationship between trophic status and polychlorinated biphenyl (PCB) distribution in 19 Swedish lakes. We analyzed PCB in water, phytoplankton, zooplankton, fish and sediment during two sampling periods, in spring and summer. The mass of Sigma PCB in the lake sediments was positively related to lake trophy, i.e. more PCBs were accumulated and buried in the sediment of eutrophic lakes than in oligotrophic lakes. In the oligotrophic lakes a greater fraction of the total PCB load was dissolved in water. We conclude that this is a result of higher sedimentation rates in eutrophic lakes and relatively lower turnover of organic carbon in the water column of the shallow, eutrophic lakes. In the stratified lakes, the amount of PCB per cubic meter in the epilimnion decreased from spring to summer. We suggest that sedimentation of plankton beneath the thermocline during stratification act as a sink process of PCBs from the epilimnion

The effect of lake trophy on lipid content and PCB concentrations in planktonic food webs

Tidskriftsartikel (refereegranskat)abstract
- We investigated the influence of trophic status on the lipid content and polychlorinated biphenyl (PCB) concentrations in planktonic food webs from 19 lakes in southern Sweden. The lipid content in phytoplankton (10-45 mum), microzooplankton (45-150 mum) and large macrozooplankton (>500 mum) was negatively related to the total phosphorus (Tot-P) concentration in lakes. The lipid content in macrozooplankton (>150 Gem) and young-of-the-year roach (Rutilus rutilus) was not related to Tot-P in lakes. On a dry mass basis (ng/g dry mass), the sum of PCB concentrations in phytoplankton and microzooplankton was negatively related to Tot-P in lakes. Thus, the PCB concentrations in phytoplankton and microzooplankton were explained by the decreasing lipid content of these fractions with increasing trophic status of lakes; and when normalized to lipid content (ng/g extractable lipid) we found no differences in PCB concentrations among lakes. We conclude that the lipid content of phytoplankton increased with increased nutrient stress, explaining the negative relationship between lake trophy and phytoplankton organochlorine (OC) concentrations on a dry mass basis. The relationship found between lipids and lake trophy in producers was not transferred in the food chain.

- Context. The HH 54 shock is a Herbig-Haro object, located in the nearby Chamaeleon II cloud. Observed CO line profiles are due to a complex distribution in density, temperature, velocity, and geometry. Aims. Resolving the HH 54 shock wave in the far-infrared (FIR) cooling lines of CO constrain the kinematics, morphology, and physical conditions of the shocked region. Methods. We used the PACS and SPIRE instruments on board the Herschel space observatory to map the full FIR spectrum in a region covering the HH 54 shock wave. Complementary Herschel-HIFI, APEX, and Spitzer data are used in the analysis as well. The observed features in the line profiles are reproduced using a 3D radiative transfer model of a bow-shock, constructed with the Line Modeling Engine code (LIME). Results. The FIR emission is confined to the HH 54 region and a coherent displacement of the location of the emission maximum of CO with increasing J is observed. The peak positions of the high-J CO lines are shifted upstream from the lower J CO lines and coincide with the position of the spectral feature identified previously in CO(10-9) profiles with HIFI. This indicates a hotter molecular component in the upstream gas with distinct dynamics. The coherent displacement with increasing J for CO is consistent with a scenario where IRAS12500 - 7658 is the exciting source of the flow, and the 180 K bow-shock is accompanied by a hot (800 K) molecular component located upstream from the apex of the shock and blueshifted by -7 km s(-1). The spatial proximity of this knot to the peaks of the atomic fine-structure emission lines observed with Spitzer and PACS ([O I]63, 145 mu m) suggests that it may be associated with the dissociative shock as the jet impacts slower moving gas in the HH 54 bow-shock.

- Background: Many full-time welders experience some sort of respiratory disorder e.g., asthma, bronchitis and metal fume fever. Thus, welding aerosols are thought to cause airway inflammation. There is a need for markers of welding aerosols in exposure assessments, and as most welding aerosols contain manganese and iron, these metals may possibly be used as an indicator. We have previously developed a novel non-invasive technique to collect endogenous particles in exhaled air (PEx). This study is designed to i) develop a method for analysis of manganese and iron in PEx and ii) investigate whether the manganese and/or iron content of PEx changes after exposure to welding aerosols. Methods: Nine individuals were experimentally exposed to welding fumes. PEx was collected at three time points for each individual; before, after and 24 hour after exposure. Analyses of PEx samples were performed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Results: Four out of nine individuals showed an increase in manganese and iron levels after exposure to welding aerosols. The mean manganese and iron concentration increased from,

- BACKGROUND:Hyperparathyroidism affects most patients with multiple endocrine neoplasia type 1 (MEN 1). This study investigates expression of the candidate MEN1 gene phospholipase C beta 3 (PLC beta 3) and expression and function of a putative calcium sensing protein (CAS) in hyperparathyroidism of MEN 1.METHODS:In 31 parathyroid glands from 17 patients with MEN 1, CAS distribution was studied immunohistochemically and parallel sections were explored for PLC beta 3 mRNA expression by in situ hybridization. Enzymatically dispersed parathyroid cells were analyzed for cytoplasmic calcium concentrations [Ca2+]i and parathyroid hormone (PTH) release.RESULTS:All glands exhibited a heterogeneously reduced CAS immunoreactivity, especially meager in nodularly assembled parathyroid cells. Calcium regulated [Ca2+]i and PTH release tended to be more deranged in the glands possessing the lowest immunostaining. Parathyroid PLC beta 3 invariably was homogeneously expressed, and this included even MEN 1 patients with reduced PLC beta 3 expression in endocrine pancreatic tumors.CONCLUSIONS:The findings support variable calcium insensitivity of [Ca2+]i and PTH release in hyperparathyroidism of MEN 1, apparently coupled to heterogeneously reduced CAS expression. For clarification of the role of PLC beta 3 in MEN 1 parathyroid tumorigenesis further study of this protein is required.

Complications related to induced abortion: a combined retrospective and longitudinal follow-up study
- 2018

Ingår i: BMC Women's Health. - : BMC. - 1472-6874. ; 18
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Induced abortion is one of the most common gynecological procedures in Sweden, but there is still little knowledge about the adverse effects. The aims of this study are to provide an overview of complications of medical and surgical abortions and to evaluate the impact of bacterial screening to prevent postabortal infections. Methods: All women who underwent induced abortion at Skaraborg Hospital between 2008 and 2015 are included in the study. Bacterial screening for chlamydia, gonorrhea, mycoplasma, and bacterial vaginosis was performed prior to the abortions. Abortion complications, categorized as bleeding, infection, or incomplete abortion were assessed in women who came in contact with the gynecological clinic within 30 days after the procedure. Results: A total of 4945 induced abortions were performed during the study period. Nearly all, 4945 (99.7%) were eligible for inclusion in the study. Medical abortions amp;lt; 12 weeks were the most common procedure (74.7%), followed by surgical abortions (17.5%), and medical abortion amp;gt; 12 weeks (7.8%). Complications were registered in 333 (6.7%) of all abortions. Among medical abortions amp;lt; 12 weeks, the complication frequency increased significantly, from 4.2% in 2008 to 8.2% in 2015 (RR 1.49, 95% 1.04-2.15). An incomplete abortion was the most common complication related to medical abortions amp;lt; 12 weeks. Of all women who tested positive for one or several bacteria at the screening and therefore received antibiotics, 1.4% developed a postabortal infection. Among those who tested negative at the screening, 1.7% developed infectious complications. Conclusions: The share of complications related to medical abortions amp;lt; 12 weeks increased significantly during 2008-2015 without any evident cause. Women who tested positive for one or several bacteria upon screening and received antibiotics experienced almost an equal proportion of postabortal infections compared to women who tested negative upon screening. The screening process seems to fulfill its purpose of reducing the risk of infectious complications.

- Objective. The intrauterine contraceptive device (IUCD) is the most preferred method of reversible contraception in the world today. The Swedish Medical Products Agency currently recommends that women who had a copper IUCD inserted around age 40 do not need to have it extracted until one year after the menopause. Design. Retrospective study. Setting. Skovde Central Hospital, Sweden. Population. All 114 women receiving in-patient treatment for pelvic inflammatory disease (PID) over five years between January 2001 and December 2005. Methods. Comparison between cases of tubo-ovarian abscesses and salpingitis with focus on the effects of IUCDs used continually for andgt; 5 years after insertion. Main outcome measures. Age-adjusted risk of PID within or after five years of use, microbiological findings in blood, intraabdominal pus, cervical secretions or on extracted IUCDs. Results. There were 31 cases of tubo-ovarian abscesses, 63 of salpingitis, four of endometritis, and 16 of mild genital infection. When comparing women with the same IUCD andgt; 5 years to women having the same IUCD andlt;= 5 years, the risk of tubo-ovarian abscess was higher than the risk of salpingitis (OR 19.7; 95% CI 4.5-87.2). The risk remained significant after adjustment for age, both on multiple regression analysis (OR 13.5; 95% CI 2.5-72.9) and in stratified analysis for the age group 35-50 years (OR 12.0; 95% CI 1.8-81.7). Blood or abdominal cultures from patients operated upon were positive in 47.7% of the sampled cases. Intestinal tract microbes and upper respiratory tract microbes were more common than sexually transmitted infection microbes. Conclusions. The current Medical Products Agency recommendation that a woman nearing the end of her reproductive phase can safely use the same IUCD for a period exceeding five years is challenged.

- Objective: Study the reproducibility of wet smear interpretation of clue cells, lactobacillary grades and leukocyte dominance with conventional bright light and phase contrast microscopy. Study design: Sets of vaginal specimens were taken from unselected consecutive women attending an outpatient gynaecology clinic. Air-dried vaginal fluid on a microscope slide was rehydrated with isotonic saline before examination by six independent international investigators. Some investigators initially used a conventional bright light microscope, followed by phase contrast technique. Results: Using phase contrast microscopy, an excellent inter-observer agreement was obtained among all investigators for clue cells detection (Kappa values from 0.69 to 0.94) and lactobacillary grades (Kappa 0.73-0.93). When conventional light microscopes were used, poor agreement was obtained for these criteria (Kappa index 0.37-0.72 and 0.80, respectively), but switching to phase contrast microscopy by the same investigators, improved Kappa to 0.83-0.85 and 0.88, respectively. The inter-observer agreement for estimation of the leukocyte/epithelial cell ratio (Kappa index 0.17-0.67) was poor, irrespective of the type of microscopy applied. Intra-observer agreement of clue cell detection and lactobacillary grading was also found to be excellent if phase contrast microscopy was used (Kappa 0.87-0.93), and poor with conventional bright light microscopy (Kappa 0.45-0.66). Conclusion: Clue cells and the lactobacillary grades are reliably identified by phase contrast microscopy in wet smears, with excellent intra- and inter-observer reproducibility agreement, and better than when simple bright light microscopy was used. Evaluation of leukocyte grading, on the other hand, was inconsistent among the different microscopists, irrespective of the type of microscope used. We propose to grade the leukocytes in a different way than searching for leukocyte dominance over epithelial cells, namely by counting them per high power field and per epithelial cell.

- In this study, an existing method for ethical analysis was extended by adding aspects of human rights and global distributional issues as framed by the United Nations (UN) Universal Declaration of Human Rights (UDHR) and the UN Millennium Development Goals (MDGs). A procedure for incorporating these issues together with environmental, safety and cost considerations into a decision making framework using multi-criteria decision analysis (MCDA) was devised. This includes a scoring system to convert qualitative ethical issues into semi-quantitative issues. The refined framework tool was tested in an illustrative case on the destruction of ammunition. The results showed that the extended framework for ethical analysis added value, for example as a way of highlighting ethical considerations in decision making. Use of the DecideIT software with its integrated MCDA improved the analysis by allowing for uncertain and imprecise values and estimations. The illustrative case results indicated that a combined alternative including recycling of metals and energetic materials had clear advantages over open detonation.

Vaginal flora and urinary and vaginal group B streptococci in early pregnancy
- 2013
-
Ingår i: Gynecology. - : Herbert Publications Limited. - 2052-6210. ; 1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Bacterial vaginosis (BV) is a risk factor for premature birth and group B streptococci (GBS) colonizing the vagina are etiological agents of neonatal infections. Significant growth of GBS in the vagina has been assumed to be detectable through urinary culture. The aim was to investigate the correlation between BV and the presence of GBS in qualitative vaginal or quantitative urinary culture, since this could predict a higher risk for perinatal morbidity.Design and setting: A consecutive prospective study of women in early pregnancy included 3101 women between 2007 and 2010, in a region of south-western Sweden.Methods: Vaginal and urine samples were obtained from women in early pregnancy at maternity health care clinics. BV was diagnosed according to the Ison/Hay classification. GBS in urine were detected in amounts as low as 100 CFU/ml. Vaginal culturing for GBS was obtained from a selected group of 481 women.Results: There was no difference in the prevalence of GBS in the urine among women with BV compared with women with lactobacilli flora (OR 0.7; 95% CI 0.4-1.1). Vaginal presence of GBS was found among 17.3% of women with BV and among 23.5% of women with lactobacilli flora (OR 0.7; 95% CI 0.3-1.4). Among the 105 women who had vaginal GBS, the urine culture of GBS was positive in only 21.9% of cases.Conclusions: Even though women with BV. have much higher concentration of bacteria in the vagina, they do not necessarily have more GBS in the vagina or urine. The modest correlation between positive vaginal culture and positive urine culture of GBS question the value of urinary culture for detection of vaginal GBS.

Pulmonary function and atherosclerosis in the general population : causal associations and clinical implications

Tidskriftsartikel (refereegranskat)abstract
- Reduced lung function is associated with cardiovascular mortality, but the relationships with atherosclerosis are unclear. The population-based Swedish CArdioPulmonary BioImage study measured lung function, emphysema, coronary CT angiography, coronary calcium, carotid plaques and ankle-brachial index in 29,593 men and women aged 50–64 years. The results were confirmed using 2-sample Mendelian randomization. Lower lung function and emphysema were associated with more atherosclerosis, but these relationships were attenuated after adjustment for cardiovascular risk factors. Lung function was not associated with coronary atherosclerosis in 14,524 never-smokers. No potentially causal effect of lung function on atherosclerosis, or vice versa, was found in the 2-sample Mendelian randomization analysis. Here we show that reduced lung function and atherosclerosis are correlated in the population, but probably not causally related. Assessing lung function in addition to conventional cardiovascular risk factors to gauge risk of subclinical atherosclerosis is probably not meaningful, but low lung function found by chance should alert for atherosclerosis.

Bacterial Vaginosis : Diagnosis, Prevalence, and Treatment
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Bacterial Vaginosis (BV) is a disorder of unknown etiology, characterized by a foul smelling vaginal discharge, loss or reduction of the normal vaginal Lactobacilli, and overgrowth of other anaerobic bacteria. Thus, it presents a formidable problem for clinicians as well as microbiologists researching its etiology, clinical course, treatment, and epidemiology. The present work focuses on the unresolved issues of the epidemiology and treatment of BV in order to provide valid methods for treatment studies of this condition and to describe the prevalence of BV in defined populations.The first study validates the use of PAP-stained smears in the diagnosis of BV. The study assesses the methods of Amsel’s clinical criteria and Nugent criteria on Gram-stain smears, against Pap-stained smears and also validates different observers. The result shows that the PAP-staining of vaginal smears is a good method in BV diagnosis; the kappa value is 0.86 (interobserver weighted kappa index) compared to 0.81 for Gram-stained smears, and 0.70 for rehydrated air-dried smears using the mean Nugent score as the criterion standard. This enables population based studies on archived PAP-stained smears from the screening of cervical cancer.In the second study, we use the knowledge gained from study one to investigate the prevalence of BV in a cohort from the population of Åland. The prevalences of BV on the Åland Islands were: 15.6 %, 11.9 %, 8.7 %, and 8.6% in 1993, 1998, 2003, and 2008, respectively. This means that the prevalence of BV decreased between1993-2008 from 15.6% to 8.6%. The confidence intervals are not overlapping, thus indicating a significant decrease in prevalence from 1993 to 2008.The third study is a prospective, double-blind placebo controlled treatment study of BV. After conventional treatment with clindamycin, the patients were treated with adjuvant treatment of Lactobacilli-loaded tampons or placebo. The study showed no differences between the treatment and the placebo group, indicating that the tampon does not work at all. There are a variety of possible explanations for the result, which are analyzed in this thesis.The fourth study aimed to evaluate whether clindamycin is retained for a long time in the vaginal mucosa, thus disturbing the Lactobacilli in an attempt to reimplant Lactobacilli in the probiotic treatment studies. In conventional treatment, it is also useful to know whether clindamycin is retained, especially when considering the pressure from antibiotics on the antimicrobial sensitivity pattern. In the study, we found that the clindamycin disappears rapidly.Conclusion: BV research requires effort from many different scientific disciplines and the riddle of this condition and its treatment can only be resolved by concerted actions in research and treatment. The vision for the future includes, among other factors, better molecular biology based diagnostic tools, and knowledge of population based bacterial floras.
