- A single genetic biomarker is unable to accurately predict the risk for venous thromboembolism (VTE) recurrence. We aimed to: (a) develop a multiple single nucleotide polymorphisms (SNPs) model to predict the risk of VTE recurrence and (b) validate a previously described genetic risk score (GRS) and compare its performance with the model developed in this study. Twenty-two SNPs, including established and putative SNPs associated with VTE risk, were genotyped in the Malmö thrombophilia study cohort (MATS; n = 1465, follow-up ~ 10 years) by using TaqMan PCR. Out of 22-SNPs, 12 had an association with the risk of VTE recurrence and were included for calculating GRSs. The risk of VTE recurrence was calculated by stratifying patients according to number of risk alleles. In 12-SNP GRS, patients with ≥ 7 risk alleles were associated with higher risk of VTE recurrence compared to patients having ≤ 6 risk alleles. In a simplified model (8-SNP GRS), the discriminative power of 8-SNP GRS was similar to that of 12-SNP GRS based on post-test probabilities (PP). Furthermore, 8-SNP GRS further improved the risk prediction of VTE recurrence in unprovoked VTE and male patients (PP% = 15.4 vs 8.3, 17.1 vs 7.2 and 19.0 vs 7.1 for high risk groups vs low risk groups in whole population, males and unprovoked VTE patients respectively). In addition, we also validated previously described 5-SNP GRS in our cohort and found that the 8-SNP GRS performed better than the 5-SNP GRS in terms of higher PP. Our results show that a multiple SNP GRS consisting of 8-SNPs may be an effective model for prediction of VTE recurrence, particularly in unprovoked VTE and male patients.

- Conclusion: This study shows a persistent trend of an increase in the incidence of carcinoma of the tongue into the twenty-first century for both sexes and all age groups except for young males. Objectives: During the last decades increased incidence of squamous cell carcinoma (SCC) of the tongue in young adults has been reported. We previously showed an increased incidence in SCC of the tongue in Scandinavia in 1960-1994, most pronounced in patients aged 20-39 years. The aim of this study was to investigate whether the trend of increased incidence of tongue cancer continued into the twenty-first century in a population-based study in the Nordic countries. Methods: Data for all reported SCCs of the tongue and base of tongue in patients aged 20-79 years during 1960-2008 were extracted from the NORDCAN registry, based on the National Cancer registries in the Nordic countries. Data from Sweden, Norway, Finland, Denmark, and Iceland were analyzed. The age groups 20-39, 40-64, and 65-79 years were studied separately as well as male and female figures. Results: In all, 12 280 cases were reported, of which 673 were diagnosed in patients aged 20-39 years. The trend of an increase persisted after 1994 in both sexes and all three age groups except in young males.

- AIM: Preterm birth is associated with a number of physical and mental health issues. The aim of this study was to find out if there was also any association between individuals born preterm in Sweden between 1984 and 2006 and the risk of unintentional injuries during childhood, adolescence and young adulthood METHODS: The study followed 2,297,134 individuals, including 5.9% born preterm, from 1985 to 2007 for unintentional injuries leading to hospitalisation or death (n=244,021). The males and females were divided into four age groups: 1-5 years, 6-12 years, 13-18 years and 19-23 years. Hazard ratios were calculated for falls, transport injuries and other injuries RESULTS: After adjusting for a comprehensive set of covariates, some of the preterm subgroups demonstrated slightly increased risks of unintentional injuries, while others showed slightly decreased risks. However, most of the estimates were borderline or non-significant in both males and females. In addition, the absolute risk differences between individuals born preterm and full term were small CONCLUSION: Despite the association between preterm birth and a variety of physical and mental health consequences, this study shows that there is no consistent risk pattern between preterm birth and unintentional injuries in childhood, adolescence and young adulthood. ©2012 The Author(s)/Acta Paediatrica ©2012 Foundation Acta Paediatrica©2012 The Author(s)/Acta Paediatrica ©2012 Foundation Acta Paediatrica.

Tidskriftsartikel (refereegranskat)abstract
- Preterm birth (PTB) is the leading cause of infant mortality worldwide. Changes in PTB rates, ranging from -90% to +30%, were reported in many countries following early COVID-19 pandemic response measures ('lockdowns'). It is unclear whether this variation reflects real differences in lockdown impacts, or perhaps differences in stillbirth rates and/or study designs. Here we present interrupted time series and meta-analyses using harmonized data from 52 million births in 26 countries, 18 of which had representative population-based data, with overall PTB rates ranging from 6% to 12% and stillbirth ranging from 2.5 to 10.5 per 1,000 births. We show small reductions in PTB in the first (odds ratio 0.96, 95% confidence interval 0.95-0.98, P value <0.0001), second (0.96, 0.92-0.99, 0.03) and third (0.97, 0.94-1.00, 0.09) months of lockdown, but not in the fourth month of lockdown (0.99, 0.96-1.01, 0.34), although there were some between-country differences after the first month. For high-income countries in this study, we did not observe an association between lockdown and stillbirths in the second (1.00, 0.88-1.14, 0.98), third (0.99, 0.88-1.12, 0.89) and fourth (1.01, 0.87-1.18, 0.86) months of lockdown, although we have imprecise estimates due to stillbirths being a relatively rare event. We did, however, find evidence of increased risk of stillbirth in the first month of lockdown in high-income countries (1.14, 1.02-1.29, 0.02) and, in Brazil, we found evidence for an association between lockdown and stillbirth in the second (1.09, 1.03-1.15, 0.002), third (1.10, 1.03-1.17, 0.003) and fourth (1.12, 1.05-1.19, <0.001) months of lockdown. With an estimated 14.8 million PTB annually worldwide, the modest reductions observed during early pandemic lockdowns translate into large numbers of PTB averted globally and warrant further research into causal pathways.

- In this article we reflect on the quality of a realist synthesis paradigm applied to the evaluation of Phase V of the WHO European Healthy Cities Network. The programmatic application of this approach has led to very high response rates and a wealth of important data. All articles in this Supplement report that cities in the network move from small-scale, time-limited projects predominantly focused on health lifestyles to the significant inclusion of policies and programmes on systems and values for good health governance. The evaluation team felt that, due to time and resource limitations, it was unable to fully exploit the potential of realist synthesis. In particular, the synthetic integration of different strategic foci of Phase V designation areas did not come to full fruition. We recommend better and more sustained integration of realist synthesis in the practice of Healthy Cities in future Phases.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Immigrant women in Sweden have lower levels of leisure time physical activity (LTPA) than Swedish-born women. The reasons are unclear, although acculturation has been suggested to play a role. METHODS: We used a cross-sectional study design to investigate the association between LTPA and two indicators of acculturation: (i) language proficiency (ability to understand news reports on the radio and television) and (ii) age at the time of migration, and if there existed a modifying effect on these hypothesized associations. The study sample consisted of 1651 women, aged 18-65, living in Sweden and born in Finland, Chile or Iraq. A postal questionnaire (translated into the women's native language) was used to collect the variables. The International Physical Activity Questionnaire was used to assess LTPA. Data were collected in 2002-05 and analyzed in 2009-10. A partial-proportional odds model was used for the analysis. RESULTS: Increased language proficiency was associated with increased LTPA [odds ratio (OR) = 2.31, 95% confidence interval (CI) = 1.57-3.41]. Country of birth modified the association. Furthermore, younger age at migration was associated with increased LTPA (OR = 1.44, 95% CI = 1.01-2.03). CONCLUSIONS: Increased language proficiency has the potential to be an important health-promoting factor among immigrant women.

Genetic and Familial Environmental Influences on the Risk for Drug Abuse: A National Swedish Adoption Study.
- 2012
-

Tidskriftsartikel (refereegranskat)abstract
- CONTEXT: Prior research suggests that drug abuse (DA) is strongly influenced by both genetic and familial environmental factors. No large-scale adoption study has previously attempted to verify and integrate these findings. OBJECTIVE: To determine how genetic and environmental factors contribute to the risk for DA. DESIGN: Follow-up in 9 public databases (1961-2009) of adopted children and their biological and adoptive relatives. SETTING: Sweden. PARTICIPANTS: The study included 18 115 adopted children born between 1950 and 1993; 78 079 biological parents and siblings; and 51 208 adoptive parents and siblings. MAIN OUTCOME MEASURES: Drug abuse recorded in medical, legal, or pharmacy registry records. RESULTS: Risk for DA was significantly elevated in the adopted offspring of biological parents with DA (odds ratio, 2.09; 95% CI, 1.66-2.62), in biological full and half siblings of adopted children with DA (odds ratio, 1.84; 95% CI, 1.28-2.64; and odds ratio, 1.41; 95% CI, 1.19-1.67, respectively), and in adoptive siblings of adopted children with DA (odds ratio, 1.95; 95% CI, 1.43-2.65). A genetic risk index (including biological parental or sibling history of DA, criminal activity, and psychiatric or alcohol problems) and an environmental risk index (including adoptive parental history of divorce, death, criminal activity, and alcohol problems, as well as an adoptive sibling history of DA and psychiatric or alcohol problems) both strongly predicted the risk for DA. Including both indices along with sex and age at adoption in a predictive model revealed a significant positive interaction between the genetic and environmental risk indices. CONCLUSIONS: Drug abuse is an etiologically complex syndrome strongly influenced by a diverse set of genetic risk factors reflecting a specific liability to DA, by a vulnerability to other externalizing disorders, and by a range of environmental factors reflecting marital instability, as well as psychopathology and criminal behavior in the adoptive home. Adverse environmental effects on DA are more pathogenic in individuals with high levels of genetic risk. These results should be interpreted in the context of limitations of the diagnosis of DA from registries.

Tidskriftsartikel (refereegranskat)abstract
- Mitochondrial dysfunction is an important factor of the aging process and may play a key role in various diseases. Mitochondrial DNA copy number (mtDNA-CN) is an indirect measure of mitochondrial dysfunction and is associated with type 2 diabetes mellitus (T2DM); however, whether mtDNA-CN can predict the risk of developing T2DM is not well-known. We quantified absolute mtDNA-CN in both prevalent and incident T2DM by well-optimized droplet digital PCR (ddPCR) method in a population-based follow-up study of middle aged (50-59 years) Swedish women (n = 2387). The median follow-up period was 17 years. Compared to those who were free of T2DM, mtDNA-CN was significantly lower in both prevalent T2DM and in women who developed T2DM during the follow-up period. Mitochondrial DNA-copy number was also associated with glucose intolerance, systolic blood pressure, smoking status and education. In multivariable Cox regression analysis, lower baseline mtDNA-CN was prospectively associated with a higher risk of T2DM, independent of age, BMI, education, smoking status and physical activity. Moreover, interaction term analysis showed that smoking increased the effect of low mtDNA-CN at baseline on the risk of incident T2DM. Mitochondrial DNA-copy number may be a risk factor of T2DM in women. The clinical usefulness of mtDNA-CN to predict the future risk of T2DM warrants further investigation.
