- This study explores how researchers analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions as they used the same data to independently test the same prominent social science hypothesis: that greater immigration reduces support for social policies among the public. In this typical case of social science research, research teams reported both widely diverging numerical findings and substantive conclusions despite identical start conditions. Researchers expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes. More than 95% of the total variance in numerical results remains unexplained even after qualitative coding of all identifiable decisions in each teams workflow. This reveals a universe of uncertainty that remains hidden when considering a single study in isolation. The idiosyncratic nature of how researchers results and conclusions varied is a previously underappreciated explanation for why many scientific hypotheses remain contested. These results call for greater epistemic humility and clarity in reporting scientific findings.

Identifying Food Consumption Patterns among Young Consumers by Unsupervised and Supervised Multivariate Data Analysis
- 2014
-
Ingår i: European Journal of Nutrition & Food Safety. - 2347-5641. ; 4:4, s. 392-403
-
Tidskriftsartikel (refereegranskat)abstract
- Although computational multivariate data analysis (MDA) already has been employed in the dietary survey area, the results reported are based mainly on classical exploratory (descriptive) techniques. Therefore, data of a Swedish and a Danish dietary survey on young consumers (4 to 5 years of age) were subjected not only to modern exploratory MDA, but also modern predictive MDA that via supervised learning yielded predictive classification models. The exploratory part, also encompassing Swedish 8 or 11-year old Swedish consumers, included new innovative forms of hierarchical clustering and bi-clustering. This resulted in several interesting multi-dimensional dietary patterns (dietary prototypes), including striking difference between those of the age-matched Danish and Swedish children. The predictive MDA disclosed additional multi-dimensional food consumption relationships. For instance, the consumption patterns associated with each of several key foods like bread, milk, potato and sweetened beverages, were found to differ markedly between the Danish and Swedish consumers. In conclusion, the joint application of modern descriptive and predictive MDA to dietary surveys may enable new levels of diet quality evaluation and perhaps also prototype-based toxicology risk assessment.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPostpartum hemorrhage is an important cause of maternal death and morbidity. However, it is unclear whether women who experience postpartum hemorrhage are at an increased risk of postpartum depression.ObjectivesTo examine whether postpartum hemorrhage is associated with postpartum depression.MethodsWe conducted a national register-based cohort study of 486,476 Swedish-born women who had a singleton livebirth between 2007 and 2014. We excluded women with pre-existing depression or who filled a prescription for an antidepressant before childbirth. We classified postpartum depression up to 12 months after giving birth by the presence of an International Classification of Diseases, version 10 (ICD-10) diagnosis code for depression or a filled outpatient prescription for an antidepressant. We used Cox proportional hazard models, adjusting for maternal sociodemographic and obstetric factors.ResultsPostpartum depression was identified in 2.0% (630/31,663) of women with postpartum hemorrhage and 1.9% (8601/455,059) of women without postpartum hemorrhage. In our unadjusted analysis, postpartum hemorrhage was not associated with postpartum depression (unadjusted hazard ratio (HR) = 1.06, 95% confidence interval (CI) 0.97-1.15). After adjusting for maternal age, parity, education, cohabitation status, maternal smoking status, and early pregnancy maternal BMI, gestational age, and birthweight, the association did not appreciably change, with confidence intervals overlapping the null (adjusted HR = 1.08, 95% CI 0.99, 1.17).ConclusionsWithin a population-based cohort of singleton women in Sweden with no prior history of depression, postpartum hemorrhage was not associated with postpartum depression.

Chronic pain related to childbirth : Prevalence, characteristics, women's experiences about its impact and support from healthcare
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Pregnancy and labour often entail pain and tissue damage, which may lead to the development of chronic pain. Globally, chronic pain, defined as pain that persists after three months, is a leading cause of lasting suffering and disability. If pain is not timely diagnosed and adequately treated it can become a chronic condition. However, among healthcare professionals, there seems to be a lack of strategies for its prevention and treatment.Aim: The aim of this thesis was to describe the prevalence and characteristics of chronic pain related to childbirth. Further aims were to explore women’s experiences of pain and its consequences as well as information and support from healthcare professionals.Methods: Study I was conducted as a prospective cohort study, Studies II and IV had a qualitative approach, and Study III was a mixed methods study with a sequential explanatory design. In Study I, as well as in the first, quantitative part of Study III, data were obtained through two self-administered questionnaires and the patient record system, Obstetrix. The first questionnaire was distributed on the maternity ward, 24–36 h after labour between April and December 2015. The second questionnaire was sent by post eight months after childbirth. Data from 1,171 women, who answered the second questionnaire, were analysed using descriptive statistics. Studies II and IV as well as the second, qualitative part of Study III, had a qualitative approach and included 20 individual semi-structured interviews. Participants in these studies consisted of the same sample, recruited among women who had reported chronic pain related to pregnancy and/or labour in Study I. The interviews were conducted between June and November 2016, recorded and transcribed verbatim. The data were processed and analysed using inductive content analysis.Results: The results of Study I showed that 17% of the women reported chronic pain related to childbirth. Approximately 80% rated their worst pain as moderate or severe and more than 40% of the women experienced pain constantly or daily. Dyspareunia related to childbirth was reported by 19% of the women, with approximately 60% experiencing their worst pain during intercourse as moderate or severe. Study II revealed that women constantly struggled with the pain and its consequences. Chronic pain had a negative impact on several aspects of women’s lives, including physical and social activities, psychological well-being, self-image, as well as their roles as partners and mothers. The results of Study III revealed that the majority of the women did not receive information about risks of developing chronic pain related to childbirth. They did not have knowledge about when and where to seek help, and half of them did not consult healthcare professionals. The lack of information also led to women feeling unprepared for the pain causing emotional distress. In addition, as Study IV revealed, when women turned to healthcare, they did not receive the attention, recognition, and support they needed. They reported not being listened to, not taken seriously, or believed by healthcare professionals and their pain was not assessed, diagnosed, or treated. The women felt abandoned after childbirth and forced to manage the condition on their own. There was an overall desire for more support and continuity regarding care as well as better knowledge among healthcare professionals.Conclusions: Chronic pain eight months after childbirth was reported by one in six women and one in five experienced dyspareunia. Approximately 80% of the women rated their worst pain as moderate or severe, and more than 40% experienced pain constantly or daily. The pain and its consequences had a negative impact on several aspects of women’s lives. In addition, women did not receive adequate information or support from healthcare. In consequence, they did not seek help or when they did, their pain was not recognised, treated, or resolved. Living with pain as well as the lack of adequate information and support from healthcare may also lead to emotional distress. Together this may contribute to women’s suffering as well as an increased risk of development and maintenance of chronic pain. This thesis indicates a need to review the content and quality of current postpartum maternal care concerning pain assessment and management, as well as to develop standards and guidelines for prevention and treatment of pain persisting after pregnancy or labour.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Access to information is essential to achieving individual empowerment; meaning the ability to exercise control, manage one's own condition and make informed decisions. However, studies have shown that information provided to women regarding physiological changes during the postpartum period and postpartum health was inadequate, incorrect, or inconsistent.METHODS: The aim of this study was to explore informational support about pain persisting after childbirth and its consequences. A sequential explanatory mixed methods design was used. In the first, quantitative phase, 1,171 women, who gave birth eight months earlier, completed a self-administered questionnaire. In the second, qualitative phase, 20 women who experienced chronic pain were interviewed. Descriptive statistics and qualitative content analysis were used to analyse the data.RESULTS: The majority of the women did not receive information about pain persisting after childbirth, or the information was insufficient or incorrect. They did not know when and where to seek help and did not consult health care professionals. In addition, the lack of information had a negative impact on women's psychological well-being. All women expressed the need to be informed by health care professionals, irrespective of the individual risk of developing chronic pain.CONCLUSIONS: Health services should ensure availability of information to give the women opportunity to achieve empowerment to make good health decisions, increase control over their health and well-being as well as to enhance their self-efficacy. We propose that a booklet or leaflet with relevant information about the risk of developing chronic pain, symptoms and treatment, along with advice about appropriate health care settings should be provided as part of antenatal or postnatal care.

Grieving over the past and struggling forward - a qualitative study of women's experiences of chronic pain one year after childbirth
- 2021

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To describe women's experiences of chronic pain related to childbirth approximately one year after labour.DESIGN: A qualitative design with face-to-face interviews analysed using inductive qualitative content analysis.PARTICIPANTS: Twenty women who reported chronic pain, with onset during pregnancy and/or following labour, approximately one year after childbirth.FINDINGS: The analysis revealed an essential theme, "Grieving over the past and struggling forward", and three categories "Mourning the losses", "Struggling with the present" and "Managing the future".CONCLUSIONS: This study provides new knowledge about women's experiences of chronic pain one year after childbirth. The pain severely reduced women´s previous ability to perform physical and social activities, negatively impacted psychological well-being and altered their self-image. Most of the women adopted a positive attitude and hoped for improved health in the future, although constantly struggling with the pain and its consequences.IMPLICATIONS FOR PRACTICE: This knowledge is particularly important as chronic pain may not diminish with time in predisposed individuals who may need help and support from health professionals in their endeavour to manage their pain. Healthcare providers, i.e. midwives, gynaecologists and general practitioners need to understand women´s experiences of chronic pain from their own perspective to improve identification and treatment of pain following childbirth, thus preventing women's suffering and potential long-term health problems. Future studies are warranted to further explore and discuss women's coping strategies, health seeking behaviour and experiences of health care.

Tidskriftsartikel (refereegranskat)abstract
- Background and aimsAlthough several studies have been conducted, knowledge about chronic pain and dyspareunia after childbirth is still limited. The aim of this study was to explore the prevalence of chronic pain 8 months after childbirth in a cohort of Swedish women. The characteristics of chronic pain, such as, pain intensity, localization and frequency as well as pain interference with daily activities were examined. An additional aim was to describe the prevalence and intensity of dyspareunia.MethodsData were obtained through two self-administered questionnaires and the patient record system, Obstetrix. The first questionnaire was distributed on the maternity ward, 24-36 h after labour, to Swedish-speaking women who had given birth to a living child (n = 1,507). The second questionnaire was sent by post 8 months after childbirth. We collected data about demographic and social characteristics, pain presence and its onset, as well as pain intensity, frequency, bodily localization and pain interference with activities of women's daily life. Results In total, 1,171 (77.7%) responded to both questionnaires and were included in the analysis. Eight months after giving birth, totally 16.7% (195/1,171) of the women reported chronic pain related to childbirth. Of these, 9.1% (106/1,171) of women reported chronic pain with onset during pregnancy, 4.5% (53/1,171) experienced chronic pain with onset following labour and 3.1% (36/1,171) of women had both chronic pain with onset during pregnancy and chronic pain with onset following labour (each participant could only appear in one of the groups). Women reported a lower prevalence of chronic pain after vaginal delivery than caesarean section (61/916, 6.7% vs. 28/255, 11%, p = 0.021, OR 1.73, 95% CI 1.1-2.8). Moreover, 19.2% (211/1,098) of women experienced dyspareunia. There was no difference regarding prevalence of dyspareunia and the mode of delivery. Of those women who had a vaginal delivery, 19.5% (167/858) experienced pain during intercourse and the corresponding number for women after caesarean section was 18.3% (44/240) (p = 0.694, OR 0.929, CI 0.6-1.3). Approximately 80% of women with chronic pain, and 60% of women that experienced dyspareunia, rated their worst pain as moderate or severe (NRS 4-10). The corresponding number regarding average chronic pain was between 50 and 70%. More than 35% of the women with chronic pain scored pain interference with daily activities as ≥4 on a 0-10 NRS.Conclusions In our study, chronic pain 8 months after childbirth was reported by one in six women and one in five of the women experienced dyspareunia. The intensity of both chronic pain and dyspareunia was reported as moderate to severe in a significant proportion of women and chronic pain interfered considerably with daily activities. Implications There is a need to raise awareness among healthcare providers of this clinical problem as well as to revise and upgrade education regarding pain after childbirth to prevent potential long-term health problems, women's suffering and increased need for health care. The development of strategies for prevention, follow-up and treatment of pain is warranted. More research, including women's experiences of pain as well as intervention studies, are also needed.

“The ignored pain” - experiences of encounters with healthcare from the perspective of women with pain persisting after childbirth : a qualitative study
- 2024
-
Ingår i: Sexual & Reproductive HealthCare. - : Elsevier. - 1877-5756 .- 1877-5764. ; 39
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: Although the prevalence of pain persisting after pregnancy or labour decreases with time, up to 35 % of women report pain 8 months to 12 years after childbirth. To prevent the development and reduce the impact of chronic pain, researchers and clinicians emphasize the importance of early diagnosis as well as timely and appropriate treatment. Previous studies have shown that when women with post-childbirth morbidities consult healthcare professionals during the first year following birth, their problems are often neglected, and they do not receive adequate treatment.Objective: To explore how women with pain persisting for eight months after childbirth experienced encounters with healthcare.Methods: A descriptive qualitative design with 20 face-to-face, semi-structured interviews. Data were analysed using inductive qualitative content analysis.Results: “Pain ignored by healthcare” was identified as an essential theme and included four categories: “Questioned pain experience,” “Inadequate pain management,” “Lost in healthcare,” and “Insufficient postpartum care “Conclusion: The women experienced that their pain was often not recognized or adequately treated, but instead ignored or trivialized. Recurring were descriptions of experienced knowledge gaps among the healthcare providers regarding pain and its management. There was an overall desire among women for a well-defined and well-functioning chain of care with better accessibility and scope.

Tidskriftsartikel (refereegranskat)abstract
- Background: The COVID-19 pandemic has altered daily routines and family functioning, led to closing schools, and dramatically limited social interactions worldwide. Measuring its impact on mental health of vulnerable children and adolescents is crucial. Methods: The Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT - www. coh-fit.com) is an on-line anonymous survey, available in 30 languages, involving >230 investigators from 49 countries supported by national/international professional associations. COH-FIT has thee waves (until the pandemic is declared over by the WHO, and 6-18 months plus 24-36 months after its end). In addition to adults, COH-FIT also includes adolescents (age 14-17 years), and children (age 6-13 years), recruited via nonprobability/snowball and representative sampling and assessed via self-rating and parental rating. Nonmodifiable/modifiable risk factors/treatment targets to inform prevention/intervention programs to promote health and prevent mental and physical illness in children and adolescents will be generated by COH-FIT. Co primary outcomes are changes in well-being (WHO-5) and a composite psychopathology P-Score. Multiple behavioral, family, coping strategy and service utilization factors are also assessed, including functioning and quality of life. Results: Up to June 2021, over 13,000 children and adolescents from 59 countries have participated in the COHFIT project, with representative samples from eleven countries. Limitations: Cross-sectional and anonymous design. Conclusions: Evidence generated by COH-FIT will provide an international estimate of the COVID-19 effect on childrens, adolescents and families, mental and physical health, well-being, functioning and quality of life, informing the formulation of present and future evidence-based interventions and policies to minimize adverse effects of the present and future pandemics on youth.

- Background: . High-quality comprehensive data on short-/long-term physical/mental health effects of the COVID-19 pandemic are needed. Methods: . The Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT) is an international, multi-language (n=30) project involving >230 investigators from 49 countries/territories/regions, endorsed by national/international professional associations. COH-FIT is a multi-wave, on-line anonymous, cross-sectional survey [wave 1: 04/2020 until the end of the pandemic, 12 months waves 2/3 starting 6/24 months threreafter] for adults, adolescents (14-17), and children (6-13), utilizing non-probability/snowball and representative sampling. COH-FIT aims to identify non-modifiable/modifiable risk factors/treatment targets to inform prevention/intervention programs to improve social/health outcomes in the general population/vulnerable subgrous during/after COVID-19. In adults, co-primary outcomes are change from pre-COVID-19 to intra-COVID-19 in well-being (WHO-5) and a composite psychopathology P-Score. Key secondary outcomes are a P-extended score, global mental and physical health. Secondary outcomes include health-service utilization/ functioning, treatment adherence, functioning, symptoms/behaviors/emotions, substance use, violence, among others. Results: . Starting 04/26/2020, up to 14/07/2021 >151,000 people from 155 countries/territories/regions and six continents have participated. Representative samples of >= 1,000 adults have been collected in 15 countries. Overall, 43.0% had prior physical disorders, 16.3% had prior mental disorders, 26.5% were health care workers, 8.2% were aged >= 65 years, 19.3% were exposed to someone infected with COVID-19, 76.1% had been in quarantine, and 2.1% had been COVID 19-positive. Limitations: . Cross-sectional survey, preponderance of non-representative participants. Conclusions: . Results from COH-FIT will comprehensively quantify the impact of COVID-19, seeking to identify high-risk groups in need for acute and long-term intervention, and inform evidence-based health policies/strategies during this/future pandemics.

Tidskriftsartikel (refereegranskat)abstract
- Background: The Collaborative Outcome study on Health and Functioning during Infection Times (COH-FIT; www.coh-fit.com) is an anonymous and global online survey measuring health and functioning during the COVID-19 pandemic. The aim of this study was to test concurrently the validity of COH-FIT items and the in-ternal validity of the co-primary outcome, a composite psychopathology "P-score". Methods: The COH-FIT survey has been translated into 30 languages (two blind forward-translations, consensus, one independent English back-translation, final harmonization). To measure mental health, 1-4 items ("COH-FIT items") were extracted from validated questionnaires (e.g. Patient Health Questionnaire 9). COH-FIT items measured anxiety, depressive, post-traumatic, obsessive-compulsive, bipolar and psychotic symptoms, as well as stress, sleep and concentration. COH-FIT Items which correlated r >= 0.5 with validated companion question-naires, were initially retained. A P-score factor structure was then identified from these items using exploratory factor analysis (EFA) and confirmatory factor analyses (CFA) on data split into training and validation sets. Consistency of results across languages, gender and age was assessed. Results: From >150,000 adult responses by May 6th, 2022, a subset of 22,456 completed both COH-FIT items and validated questionnaires. Concurrent validity was consistently demonstrated across different languages for COH-FIT items. CFA confirmed EFA results of five first-order factors (anxiety, depression, post-traumatic, psychotic, psychophysiologic symptoms) and revealed a single second-order factor P-score, with high internal reliability (omega = 0.95). Factor structure was consistent across age and sex. Conclusions: COH-FIT is a valid instrument to globally measure mental health during infection times. The P-score is a valid measure of multidimensional mental health.

A Prima Vista – Possibillities and Challenges with Practice-based Research in Music Education
- 2021
-
Konferensbidrag (refereegranskat)abstract
- In 2017 the Swedish Government commissioned four Universities to plan and execute a project aiming to develop and test different models for long-term collaboration between Universities and Colleges and heads of Schools concerning practice-based research (Utbildningsdepartementet, 2018). This should be seen in the light of the decree in the Swedish education act from 2010, that declares that the Swedish compulsory school shall be founded in scientific basis and proven experience (SFS 2010:800; Norrestam & Alfredson, 2018).These four Universities became the core of a practice-based test project between Higher Education and School, called ULF (Utbildning, Lärande, Forskning) [in English ELR, Education, Learning, Research]. The four Universities have collaborated with other Universities and Colleges and formed four hubs in the ULF project network. The Royal College of Music (RCM) in Stockholm has been a part of the project through the hub administrated by Uppsala University. The trial period ends in 2021, and throughout the period RCM has been conducting four practice-based research projects where music teachers in the compulsory school have worked together with researchers from the college in pairs and in one case in a trio, researching areas that have been identified by the music teachers as important for them in their daily work. These research areas have been: Leadership in the music-classroom; Interventions for musical knowledge development and participation; Music education and digitalization; and Norm-critical music education.Five music teachers and four researchers together have developed multifaceted knowledge concerning, of course, the research areas of interest, but also about matters concerning arrangements supporting practice-based research. This could be called incidental findings, but we argue that these areas of interest may, in fact be part of the main findings, of the study made by the RCM, as well as of the main project nationally. The results are presented in an anthology called “A Prima Vista” which will be completed in January 2021.In the symposia we would like to present results and further discuss:- How to define practice-based research? The definition of the term practice-based or practice-conducted research is not an easy on to make?- The ethical codex for conducting studies that include humans, is in Sweden not updated to adequately meet the special issues that arises when practicing teachers are partaking in research that their head of the school department is engaged in. This concerns i.e., the matter of anonymization and bias.- How do one practically take on the task of practice-based research? Little is written in Sweden on organizational matters. Our project has shown that issues like schedules, access to resources, and substitute teachers are just a few of many pressing organizational matters.- Findings from the collaborative part-studies.

Lead, mercury, and cadmium in blood and their relation to diet among Swedish adults
- 2013
-
Ingår i: Food and Chemical Toxicology. - : Elsevier BV. - 0278-6915. ; 57, s. 161-9

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present study was to examine the body burden of lead (Pb), mercury (Hg), and cadmium (Cd) in blood among Swedish adults and the association between blood levels, diet and other lifestyle factors. The study was based on a subgroup (n = 273) of the national survey Riksmaten 2010-2011 (4-day food records and questionnaire). Lead, Hg, and Cd were measured in whole blood, and Cd additionally in urine, by mass or fluorescence spectrometry methods. The median values (5-95th percentiles) of the metals in blood were as follows: Pb: 13.4 (5.8-28.6) mu g/L, Hg: 1.13 (0.31-3.45) mu g/L, and Cd: 0.19 (0.09-1.08) mu g/L. All three metals increased with increasing age. Lead levels in blood were positively associated with intakes of game and alcohol, Hg was related to fish intake, and blood Cd related to smoking and low iron stores and to a low meat intake. Body burdens of the studied metals were generally below health based reference values, but several individuals had blood Pb levels above the reference point for possible nephrotoxic and developmental neurotoxic effects. As health effects cannot be excluded, individuals with high Pb exposure should aim at decreasing their body burden, both from food and from other exposure routes. (c) 2013 Elsevier Ltd.

En båge genom tiden - ritualer kring en göteborgshistoria. Om Flickläroverket i Artisten
- 2024
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- 1929 bildades Göteborgs första Högre allmänna läroverk för Flickor – Flickläroverket som fick en byggnad 1935 i det kulturella centrumet, Götaplatsen. Efter några år som Kjellbergska gymnasiet, sedan Komvux, blev byggnaden del av Artisten, Högskolan för scen och musik, HSM 1992. Byggnaden har burit kvinnors utbildning, konst och kultur över många generationer, en minneskedja som nu är bruten. Boken - En båge genom tiden – ritualer kring en göteborgshistoria – en konst- och forskningsantologi – är resultatet av de offentliga minnesdagar där de deltagande drygt 200 kvinnorna (70– 97 år) som varit elever på Flickläroverket, studenter vid Artisten, konstnärer och forskare – bidrog till och deltog i gestaltande ritualer, minnesrum, dans, utställningar och samtal som gav liv åt en utbildningskultur och konst som berört samhället i generationer. I boken bidrar ett 20-tal Göteborgsbaserade konstnärer och forskare med olika perspektiv på byggnadens poetiska, sociala och konstnärliga dimensioner. Bland annat beskrivs återskapandet av Bågdansen, som dansades varje år vid Lucia mellan 1934-1972. Här beskrivs även den medie-debatt som ledde till räddningen av målningen Dansen av Nils Nilsson från 1935 och hur nedtagningen gick till. Tillsammans med ett rikt foto- och bildmaterial, filmdokumentationer och ett ljudarkiv utgör boken ett tidsdokument där konst fungerar som minnesbärare över tid och rum.

- Background: Dizziness is a very common complaint. The frequency of dizziness increases with age. It affects quality of life negatively for older persons in several ways. Objectives: This study intended to investigate which variables (physical activity, loneliness, health complaints, need of help for daily living and falls) differed between those with and without dizziness and also to investigate which factors affected quality of life among older persons with dizziness. Method: An age-stratified, randomised sample of senior citizens-aged 75 or older - living in the south of Sweden (n = 4,360) answered a questionnaire concerning demographic data, social network, health complaints and diseases, feelings of loneliness, quality of life (Short Form 12), frequency of falls and activities. Results: Dizziness was associated with an increased risk of falling. Falls in the last 3 months were reported in 31% of the subjects with dizziness compared to 15% among those without (p andlt; 0.001). Dizziness also correlated with depression, with 42.5% feeling depressed among the elderly reporting dizziness as compared with 13.2%. Exercise, both light (i.e. go for a walk) or heavy (i.e. work in the garden), correlated with reduced risk of low quality of life among older, dizzy persons, both mental (light exercise OR 0.58; heavy OR 0.48) and physical (light OR 0.62; heavy OR 0.21). The proportion of dizzy persons doing light exercise was 75.6% versus 87.4% among the not dizzy (p andlt; 0.001). Exercise reduces the risk of falling and the risk of being depressed, and increases quality of life. Conclusion: Even light exercise seems beneficial both for improving quality of life and to decrease the risk of falling, which in turn will lower the mortality rate. Older persons reporting dizziness should be encouraged and perhaps helped to exercise. If one could increase physical activity among the elderly, it would reduce the number of falls, diminish medical costs, suffering for the individual, and be of paramount medicosocial importance for society.

- Short-lived anthropogenic climate forcers (SLCFs), such as sulfate aerosols, affect both climate and air quality. Despite being short-lived, these forcers do not affect temperatures only locally; regions far away from the emission sources are also affected. Climate metrics are often used in a policy context to compare the climate impact of different anthropogenic forcing agents. These metrics typically relate a forcing change in a certain region with a temperature change in another region and thus often require a separate model to convert emission changes to radiative forcing (RF) changes. In this study, we used a coupled Earth system model, NorESM (Norwegian Earth System Model), to calculate emission-to-temperature-response metrics for sulfur dioxide (SO2) emission changes in four different policy-relevant regions: Europe (EU), North America (NA), East Asia (EA) and South Asia (SA). We first increased the SO2 emissions in each individual region by an amount giving approximately the same global average radiative forcing change (-0.45 Wm(-2)). The global mean temperature change per unit sulfur emission compared to the control experiment was independent of emission region and equal to similar to 0.006 K(TgSyr(-1))(-1). On a regional scale, the Arctic showed the largest temperature response in all experiments. The second largest temperature change occurred in the region of the imposed emission increase, except when South Asian emissions were changed; in this experiment, the temperature response was approximately the same in South Asia and East Asia. We also examined the non-linearity of the temperature response by removing all anthropogenic SO2 emissions over Europe in one experiment. In this case, the temperature response (both global and regional) was twice that in the corresponding experiment with a European emission increase. This non-linearity in the temperature response is one of many uncertainties associated with the use of simplified climate metrics.

- Background: Children with speech sound disorders (SSD) form a heterogeneous group that differs in terms of underlying cause and severity of speech difficulties. Orofacial dysfunction and malocclusions have been reported in children with SSD. However, the association is not fully explored. Objectives: Our aims were to describe differences in orofacial function and malocclusion between a group of children and adolescents with compared to without SSD and to explore associations between those parameters among the group with SSD. Methods: A total of 105 participants were included, 61 children with SSD (6.0-16.7 years, mean age 8.5 +/- 2.8, 14 girls and 47 boys) and 44 children with typical speech development (TSD) (6.0-12.2 years, mean age 8.8 +/- 1.6, 19 girls and 25 boys). Assessments of orofacial function included an orofacial screening test and assessment of bite force, jaw stability, chewing efficiency, and intraoral sensory-motor function. Possible malocclusions were also assessed. Result: Children with SSD had both poorer orofacial function and a greater prevalence of malocclusion than children with TSD. Furthermore, children with SSD and poorer orofacial function had a greater risk of malocclusion. Conclusion: Our result suggests that children with SSD are more prone to having poorer orofacial function and malocclusion than children with TSD. This illustrates the importance of assessing coexisting orofacial characteristics in children with SSD, especially since orofacial dysfunction may be linked to an increased risk of malocclusion. This result highlights the need for a multiprofessional approach.

- Preterm delivery is a major global public health challenge. The objective of this study was to determine how the preterm delivery rates differ throughout a country of very high human-development index and to explore rural versus urban environmental and socio-economic factors which might be responsible for this variation.A population-based study was performed using data from the Swedish Medical Birth Register 1998 to 2013. Sweden was chosen as a model because of its validated routinely collected data and availability of individual social data. The total population comprised 1 335 802 singleton births. Multiple linear regression was used to adjust gestational age for known risk factors (maternal smoking, ethnicity, maternal education, maternal age, height, fetal gender, maternal diabetes, maternal hypertension and parity). A second and a third model were subsequently fitted allowing separate intercepts for each municipality (as fixed or random effects). Adjusted gestational ages were converted to preterm delivery rates and mapped to maternal residential municipalities. Additionally, the effects of six rural versus urban environmental and socio-economic factors on gestational age were tested using simple weighted linear regression.The study population preterm delivery rate was 4.12%. Marked differences from the overall preterm delivery rate were observed (rate estimates ranged from 1.73% - 6.31%). Statistical significance of this heterogeneity across municipalities was confirmed by a chi-squared test (p<0.001). Around 20% of the gestational age variance explained by the full model (after adjustment for known variables described above) could be attributed to municipality-level effects. In addition, gestational age was found to be longer in areas with higher fraction of built upon land and other urban features.After adjusting for known risk factors large geographical differences in rates of preterm delivery remain. Additional analyses to look at the effect of environmental and socio-economic factors on gestational age revealed an increased gestational age in urban areas. Future research strategies could focus on investigating the urbanity effect to try to explain the preterm delivery variation across countries with a very high human-development index.

- Clovis, with its distinctive biface, blade and osseous technologies, is the oldest widespread archaeological complex defined in North America, dating from 11,100 to 10,700 C-14 years before present (BP) (13,000 to 12,600 calendar years BP)(1,2). Nearly 50 years of archaeological research point to the Clovis complex as having developed south of the North American ice sheets from an ancestral technology(3). However, both the origins and the genetic legacy of the people who manufactured Clovis tools remain under debate. It is generally believed that these people ultimately derived from Asia and were directly related to contemporary Native Americans(2). An alternative, Solutrean, hypothesis posits that the Clovis predecessors emigrated from southwestern Europe during the Last Glacial Maximum(4). Here we report the genome sequence of a male infant (Anzick-1) recovered from the Anzick burial site in western Montana. The human bones date to 10,705 +/- 35 C-14 years BP (approximately 12,707-12,556 calendar years BP) and were directly associated with Clovis tools. We sequenced the genome to an average depth of 14.4x and show that the gene flow from the Siberian Upper Palaeolithic Mal'ta population(5) into Native American ancestors is also shared by the Anzick-1 individual and thus happened before 12,600 years BP. We also show that the Anzick-1 individual is more closely related to all indigenous American populations than to any other group. Our data are compatible with the hypothesis that Anzick-1 belonged to a population directly ancestral to many contemporary Native Americans. Finally, we find evidence of a deep divergence in Native American populations that predates the Anzick-1 individual.

Endothelin and nitric oxide in the fetoplacental circulation
- 2004

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Normal fetal growth and development depend on a satisfactory uteroplacental and fetoplacental blood flow. This will ensure an adequate gaseous exchange and nutritional supply to the fetus. The importance of maintaining an adequate blood flow in both these circulations is emphasized in disease states, such as preeclampsia and intrauterine growth retardation, where blood flow is compromised and perinatal outcome impaired. The control of the blood flow within the fetoplacental circulation has been much studied but is not fully understood. The general aim of the thesis was to study the physiology of placental arteries with special regard to endothelin and nitric oxide, two of the most potent vasoactive agents known, and furthermore to investigate the role of endothelin and the cytokine M-CSF in amniotic fluid. Methods: Placentas from normal pregnancies were collected, arteries were dissected and mounted in organ baths where the tension was recorded isometrically with a Grass FT03C force-displacement transducer and registered on a polygraph. Agonist and antagonists were added and contraction and relaxation of the vessels were registered. The amount of cGMP in the vessels was analysed by immunoassay. The distribution of investigated substances in the vessels was analyzed by immunohistochemistry. Primary cultures of human amniocytes were established and their ability to produce endothelin- 1 and M-CSF in response to interleukin-1 were analysed by immunoassay. Amniotic fluid was collected from pregnant women with suspect lUGR in conjunction with karyotyping and endothelin-1 and M-CSF were analysed by immunoassay. Results and conclusion: We found that ETA- and ETB-receptors are expressed in the vascular wall of placental arteries, and that endothelin-1 contracts human placental arteries through both ETA- and ETBreceptors. We also found that endothelial nitric oxide synthase is expressed in placental arteries, and that nitric oxide strongly affects contraction tone in human placental arteries. Nitric oxide induced relaxation of human placental arteries was mediated partly by cGMP and partly through direct activation of potassium channels. Endothelin- 1 and M-CSF are colocalized in human amniotic membrane cells and secreted into amniotic fluid. In summary, our data support an important role for ETA and NO in the regulation of vascular tone in the fetoplacental circulation.
