- A well-functioning placenta is essential for fetal and maternal health throughout pregnancy. Using placental weight as a proxy for placental growth, we report genome-wide association analyses in the fetal (n=65,405), maternal (n=61,228) and paternal (n=52,392) genomes, yielding 40 independent association signals. Twenty-six signals are classified as fetal, four maternal and three fetal and maternal. A maternal parent-of-origin effect is seen near KCNQ1. Genetic correlation and colocalization analyses reveal overlap with birth weight genetics, but 12 loci are classified as predominantly or only affecting placental weight, with connections to placental development and morphology, and transport of antibodies and amino acids. Mendelian randomization analyses indicate that fetal genetically mediated higher placental weight is causally associated with preeclampsia risk and shorter gestational duration. Moreover, these analyses support the role of fetal insulin in regulating placental weight, providing a key link between fetal and placental growth.

- ObjectivesTo estimate the incidence of non-vertebral fractures in ankylosing spondylitis (AS) compared with the general population.MethodsNationwide register-based cohort study including patients with AS (n=11 611, 65% men, mean age 48 years), and matched general population controls (n=58 050). Five prespecified fracture outcomes: (1) non-vertebral; (2) fracture of the proximal humerus, distal forearm or hip; (3) proximal humerus; (4) distal forearm and (5) hip) were identified through register linkages with follow-up 2007-2016. We used Poisson regression to calculate incidence rates (IRs), number of fractures per 1000 person-years at risk and IR ratios (IRRs), overall and by sex and age. IRRs were adjusted for history of any prior fracture.ResultsIRs (men/women) for non-vertebral fracture in AS were 11.9 (95% CI 11.0 to 12.9)/14.5 (95% CI 13.1 to 16.1) and in controls 10.0 (95% CI 9.7 to 10.4)/11.8 (95% CI 11.1 to 12.4), IRR (men/women) 1.2 (95% CI 1.1 to 1.3)/1.2 (95% CI 1.1 to 1.4). IRs (men/women) for fractures of the humerus, forearm or hip in AS were 4.0 (95% CI 3.5 to 4.6)/6.3 (95% CI 5.4 to 7.3) and in controls 2.7 (95% CI 2.5 to 2.9)/5.5 (95% CI 5.1 to 6.0), IRR (men/women) 1.5 (95% CI 1.3 to 1.7)/1.1 (95% CI 0.9 to 1.3). IRRs were statistically significantly elevated in men with AS versus controls for forearm fracture (1.4 (95% CI 1.1 to 1.7)) and hip fracture (1.8 (95% CI 1.4 to 2.3)), whereas not in women with AS where the IRRs were 1.1 (95% CI 0.9 to 1.4) and 1.0 (95% CI 0.6 to 1.4). For humerus fracture, IRRs were 1.4 (95% CI 0.99 to 1.9) in men with AS versus controls and 1.1 (95% CI 0.8 to 1.6) in women.ConclusionsBoth men and women with AS have a slightly higher risk of non-vertebral fractures than the general population. A statistically significantly higher risk of fractures of the proximal humerus, distal forearm or hip was found in men with AS in comparison to general population, where the relative risk was especially pronounced for hip fracture.

Peers, policy, and attitudes as drivers of antibiotic prescribing
- 2021
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- In this study we investigated how treatment norms about antibiotic use affect a doctor´s decision to prescribe antibiotics. We also investigated the attitudes and behavior of the same physicians as private persons. We find that compared with ordinary citizens, physicians are more worried and more well-informed about antibiotic resistance and use, yet they consume more antibiotics and are less willing to limit their personal use of antibiotics. There is a strong correlation between a doctor´s decision not to prescribe and the treatment norms, i.e., the perception of the common choice among physicians considering antibiotics prescription and the guidelines of antibiotics use. We also find a strong connection between professional and private attitudes: Although physicians themselves on average use more antibiotics than the general public, those who are willing to abstain from using antibiotics as a private person are also more willing not to prescribe antibiotics to their patients.

Tidskriftsartikel (refereegranskat)abstract
- Noninvasive prenatal testing (NIPT), using cell-free fetal DNA, has increasingly been adopted as a screening tool for fetal aneuploidies. Several studies have discussed benefits and limitations of NIPT compared to both ultrasound and invasive procedures, but in spite of some shortcomings NIPT has become extensively used within the last five years. This study aims to describe the current use of NIPT in Europe, Australia and the USA.We conducted a survey to describe the current use of NIPT. Colleagues filled in a simple email-based questionnaire on NIPT in their own country, providing information on: 1) Access to NIPT, 2) NIPT's chromosomal coverage, 3) financial coverage of NIPT for the patient and 4) the proportion of women using NIPT in pregnancy. Some data are best clinical estimates, due to a lack of national data.In Europe, 14 countries have adopted NIPT into a national policy/program. Two countries (Belgium and the Netherlands) offer NIPT for all pregnant women, whereas most other European countries have implemented NIPT as an offer for higher risk women after first trimester screening. In Australia, either Combined First Trimester Screening (cFTS) or NIPT are used as primary prenatal screening tests. In the USA, there are no national consensus policies on the use of NIPT, however, NIPT is widely implemented. In most European countries offering NIPT, the proportion of women using NIPT is well below 25%. In the Netherlands, Austria, Italy, Spain and most Australian and American States, 25-50% of women have NIPT performed and only in Belgium it is above 75%. In most countries NIPT reports on trisomy 13, 18 and 21, and often also on sex chromosome aneuploidies. Only in Belgium, the Netherlands, Lithuania, Greece, Cyprus and Italy is NIPT offered predominantly as a genome-wide test (including some microdeletions or a whole genome coverage).NIPT has been widely adopted throughout Europe, Australia and the USA, but only some countries/states have a national policy on the use of NIPT. The variation in NIPT utilization is considerable.

Technological discontinuities and the climate transition in Europe: The role of policy in two traditions of economic thinking
- 2021
-
Ingår i: The European Union and the Technology Shift. - Cham : Springer International Publishing. ; , s. 57-83

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter discusses how different analytical perspectives affect what policy interventions are deemed warranted and effective in supporting the industrial transformation required to reach climate neutrality. The development of wind and solar power over the last 40 years gives hope and provides useful examples of successful policies. However, the European Commission has for long opposed many of these policies, due to a narrow focus on market failures and static cost efficiency derived from a neoclassical economics perspective. Recent documents in the EU indicate a new focus on innovation and industrial change, which may enhance the EU's ability to lead the climate transition. For this, a broader analytical perspective is required, such as the technological innovation systems approach, which stresses dynamic long-term efficiency, acknowledges the need for technology-specific policies, including market formation, and uses system weaknesses as guide to policy intervention.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: We aimed to determine the prevalence of cardiovascular risk factors in patients with psoriatic arthritis (PsA) followed at a large Swedish Rheumatology Clinic, and to compare differences in cardiovascular risk factors between men and women with PsA and with the general population. Method: A questionnaire was sent to patients with PsA registered at the Rheumatology Clinic at Sahlgrenska University Hospital, Gothenburg (n=982). Comparisons with the general population were made using data from the Swedish National Public Health Survey. Descriptive statistics are presented. Body mass index (BMI) was calculated using self-reported height and weight. Results: Overall, 692 (70.6%) of the patients with PsA responded. The mean±sd age was 55.6±11.4years and 52% were women. Obesity (BMI ≥30 kg/m2) was more prevalent (p<0.001) in patients with PsA (28.6%) than in matched subjects from the general population (16.3%). Hypertension was also more prevalent (p<0.001) in PsA (40.3%) than in matched subjects from the general population (24.1%), as was diabetes, with a prevalence of 10.5% in the PsA population compared with 6.2% in matched subjects (p<0.001). Conclusion: We found obesity to be highly overrepresented in patients with PsA compared with matched subjects from the general population. This difference was particularly seen in women with PsA. Hypertension and ever smoking were also more prevalent in women with PsA compared with matched subjects from the general population.

Tidskriftsartikel (refereegranskat)abstract
- In this post hoc analysis of a previously published study, we compared cytokines and adipokine levels in women and men with psoriatic arthritis (PsA) at baseline (BL) and 6 months (M6) following a weight loss intervention.Patients with PsA (n=41) between 25 and 75 years of age, with body mass index (BMI)≥33 kg/m2 were included in a weight loss intervention with a very low energy diet (VLED) for 12 or 16 weeks depending on BL BMI<40 or ≥40 kg/m2. As controls (n=39), obese individuals, already planned for VLED treatment were recruited and matched for sex, age and weight to the patients with PsA. Cytokines and adipokines were measured at BL and M6.At BL, serum levels of interleukin (IL)-23, leptin and high molecular weight-adiponectin were higher in women with PsA compared with men, whereas serum levels of interferon (IFN)-γ, IL-12/IL-23 p40 and IL-13 were significantly lower in women. Serum IL-23 was significantly reduced at M6 compared with BL in women but not in men with PsA. In women with PsA, the reduction in IL-23 at M6, ∆IL-23, were positively correlated with ∆Disease Activity Score 28 C reactive protein (CRP) (Spearman's correlation (rS)=0.486, p=0.016), ∆CRP (rS=0.468, p=0.021), ∆leptin (rS=0.683, p<0.001) and negatively correlated with ∆total-adiponectin (rS=-0.433, p=0.035). Also in women, ∆Disease Activity in Psoriatic Arthritis was positively correlated with ∆tumour necrosis factor-α (rS=0.417, p=0.034), ∆IL-1β (rS=0.550, p=0.034), ∆IFN-γ (rS=0.414, p=0.035) and ∆leptin (rS=0.410, p=0.038). None of these correlations were significant in men with PsA.Women and men with PsA differed with regard to serum levels of cytokines and adipokines before and after weight loss.

- The COVID-19 pandemic has challenged the societies and health care systems globally, and resulted in many social and physical distancing restrictions to limit the spread of SARS-CoV-2. These restrictions have also likely affected the frequency of intimate contacts and the spread of sexually transmitted infections (STIs). Compared to most other countries, Sweden especially in Spring-Autumn 2020 pursued mainly milder voluntary, i.e. not mandatory enforced by laws, recommended restrictions and the impacts of these on society and spread of STIs remain largely unknown. We describe the potential impact of the COVID-19 pandemic on the national and regional incidence, epidemiology and diagnostic testing of chlamydia and gonorrhoea in Sweden in 2020. Compared to 2019, we found a significant decrease in incidence of chlamydia (-4.5%) and gonorrhoea (-17.5%), and in diagnostic testing (-10.5% for chlamydia, -9.4% for gonorrhoea) in 2020. However, the decrease in chlamydia incidence, which has mainly been decreasing last 10 years, was not significant when compared with the average incidence in 2017-2019. The largest decrease in national incidence of both infections was observed among young and heterosexual patients, however some Swedish regions showed an increased incidence, particularly of chlamydia. Increased "internet-based self-sampling" testing approach partly compensated for a decreased attendance at STI clinics. Studies, including sexual behavior, prevention, reasons for attending STI health care, STIs in different anatomical sites, and management of STIs, are required to elucidate the impact of COVID-19-associated social and physical distancing restrictions on sexual activity and the incidence and epidemiology of chlamydia and gonorrhoea in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common upper respiratory tract complication where the pathogenesis is largely unknown. Herein, we investigated the transcriptome profile in nasal mucosa biopsies of CRSwNP patients and healthy individuals. We further integrated the transcriptomics data with genes located in chromosomal regions containing genome-wide significant gene variants for COVID-19. Among the most significantly upregulated genes in polyp mucosa were CCL18, CLEC4G, CCL13 and SLC9A3. Pathways involving "Ciliated epithelial cells" were the most differentially expressed molecular pathways when polyp mucosa and non-polyp mucosa from the same patient was compared. Natural killer T-cell (NKT) and viral pathways were the most statistically significant pathways in the mucosa of CRSwNP patients compared with those of healthy control individuals. Upregulated genes in polyp mucosa, located within the genome-wide associated regions of COVID-19, included LZTFL1, CCR9, SLC6A20, IFNAR1, IFNAR2 and IL10RB. Interestingly, the second most over-expressed gene in our study, CLEC4G, has been shown to bind directly to SARS-CoV-2 spike's N-terminal domain and mediate its entry and infection. Our results on altered expression of genes related to cilia and viruses point to the de-regulation of viral defenses in CRSwNP patients, and may give clues to future intervention strategies.
