Konferensbidrag (refereegranskat)abstract
- The paper reports on the availability and use of mobile resources by newly arrived Arabic migrants in Sweden, and how the resources meet migrants’ integration needs. Analysis of websites and applications (hereafter apps) in combination with focus group interviews is used. Results show that though a variety of resources are available, translation and vocabulary apps are primarily used. Possible reasons are lack of connection in language training resources to migrants’ immediate needs such as employment and education, accommodation, contact with locals and societal information (Ager & Strang, 2008). Cultural differences might be influential for Arabic-speakers’ low use of chat apps for communication with locals.

- The purpose of this study is to investigate the mobile activities newly arrived migrants are engaged in when learning the Swedish language and about Swedish culture and society. Further, the study also explores the use of a mobile application (app) provided to the newly arrived migrants to use for pronunciation practice. The study involved 38 newly arrived Arabic speaking migrants participating in an introduction program of the Swedish language and Swedish culture provided by the Swedish government. The participants were divided into two groups: a control group who received training according to the traditional introduction programme and an experimental group who used a mobile app for pronunciation training as a complement to the programme. We applied a combination of qualitative and quantitative methods for data collection and analysis. The participants were interviewed about their use of mobile phones as well as recorded in a number of activities inside and outside the classroom to compare their language evolvement. In addition, surveys, logging of weekly mobile activities and observations were performed. The results show that the participants used a wide range of different mobile tools, both inside and outside the classroom. However, they used the mobiles mostly for communication with their family and friends rather than for communication with Swedes and learning Swedish. Further, compared to the -control group, the experimental group showed an improved speech tempo and self-confidence in speaking. The study thus indicates that focused linguistic training with a pronunciation app is useful for developing spoken language skills, which can lead to improved integration. The participants expressed need and interest in having more mobile apps for both language and culture training.

- Exploration of new strategies for the prevention of breast cancer metastasis is justifiably at the center of clinical attention. In this study, we combined a computational biology approach with mechanism-based preclinical trials to identify inhibitors of activin-like receptor kinase (ALK) 1 as effective agents for blocking angiogenesis and metastasis in breast cancer. Pharmacologic targeting of ALK1 provided long-term therapeutic benefit in mouse models of mammary carcinoma, accompanied by strikingly reduced metastatic colonization as a monotherapy or part of combinations with chemotherapy. Gene-expression analysis of breast cancer specimens from a population-based nested case-control study encompassing 768 subjects defined endothelial expression of ALK1 as an independent and highly specific prognostic factor for metastatic manifestation, a finding that was corroborated in an independent clinical cohort. Overall, our results suggest that pharmacologic inhibition of endothelial ALK1 constitutes a tractable strategy for interfering with metastatic dissemination of breast cancer.

- Whether young age at diagnosis of breast cancer is an independent risk factor for death remains controversial, and the question whether young age should be considered in treatment decisions is still to be answered. From a population-based cohort of 22,017 women with breast cancer, all women < 35 years (n = 471) were compared to a random sample of 700 women aged 35-69 years from the same cohort. Information on patient and tumor characteristics, treatment, and follow-up was collected from the medical records. Tissue microarrays were produced for analysis of classical biomarkers. Breast cancer-specific survival (BCSS), distant disease-free survival (DDFS), and locoregional recurrence-free survival (LRFS) by age were compared using women 50-69 years as reference. At 10 years follow-up, women < 35 years and 35-39 years had a worse BCSS [age < 35 years 69 % (HR 2.75, 95 % CI 1.93-3.94), age 35-39 years 76 % (HR 2.33, 95 % CI 1.54-3.52), age 40-49 years 84 % (HR 1.53, 95 % CI 0.97-2.39), and age 50-69 years 89 % (reference)]. The worse BCSS was statistically significant in stages I-IIa and Luminal B tumors. At multivariate analysis age < 35 years and 35-39 years confined a risk in LRFS (HR 2.13, 95 % CI 1.21-3.76 and HR 1.97, 95 % CI 1.06-3.68) but not in DDFS and BCSS. In the subgroup of women < 40 years with luminal tumors stage I-IIa, low age remained an independent risk factor also in DDFS (HR 1.87, 95 % CI 1.03-3.44). Young women have a high risk of systemic disease even when diagnosed in an early stage. The excess risk of relapse is most pronounced in Luminal B tumors, where low age is an independent prognostic factor of DDFS and LRFS.

Tidskriftsartikel (refereegranskat)abstract
- The long-term mortality remains unknown in women diagnosed with breast cancer in situ (BCIS). Here, we assessed the cause-specific mortality in BCIS patients. This population-based cohort study included 12,243 women diagnosed with BCIS in Sweden between 1980 and 2011. Patients were followed until death, emigration, or 31 December 2013, whichever came first. The 30-year cumulative incidence of breast cancer-specific mortality was 6.3%, which is considerably lower than 49.7% observed for other-cause mortality. Women diagnosed with BCIS were more likely to die from breast cancer (standardized mortality ratio [SMR], 3.85; 95% CI, 3.47-4.27) but less likely to die from cardiovascular disease (SMR, 0.88; 95% CI, 0.82-0.95) than women in the general population. Specifically, the SMRs for breast cancer-specific mortality decreased over time from 5.19 (95% CI, 3.95-6.81) among BCIS diagnosed during 1980-1989 to 3.03 (95% CI, 2.35-3.91) among those diagnosed during 2000-2011. Furthermore, higher risk of death from other causes was seen among those with older age at BCIS diagnosis, lower levels of education, nulliparity, higher Charlson Comorbidity Index, and being hospitalized before BCIS diagnosis; whereas, lower risk of death from breast cancer was seen among BCIS diagnosed in the later time period and those with younger age at first birth. We conclude that most women diagnosed with BCIS die from causes other than breast cancer, which highlights the need for actions not only to reduce nonbreast cancer mortality but also to identify patient where extensive curative BCIS treatment is not adding to survival.

- The relevance of the intrinsic subtypes for clinical management of metastatic breast cancer is not comprehensively established. We aimed to evaluate the prevalence and prognostic significance of drifts in tumor molecular subtypes during breast cancer progression. A well-annotated cohort of 304 women with advanced breast cancer was studied. Tissue microarrays of primary tumors and synchronous lymph node metastases were constructed. Conventional biomarkers were centrally assessed and molecular subtypes were assigned following the 2013 St Gallen guidelines. Fine-needle aspirates of asynchronous metastases were transcriptionally profiled and subtyped using PAM50. Discordant expression of individual biomarkers and molecular subtypes was observed during tumor progression. Primary luminal-like tumors were relatively unstable, frequently adopting a more aggressive subtype in the metastases. Notably, loss of ER expression and a luminal to non-luminal subtype conversion was associated with an inferior post-recurrence survival. In addition, ER and molecular subtype assessed at all tumor progression stages were independent prognostic factors for post-recurrence breast cancer mortality in multivariable analyses. Our results demonstrate that drifts in tumor molecular subtypes may occur during tumor progression, conferring adverse consequences on outcome following breast cancer relapse.

- Family history of cancer is a well-known risk factor but the role of family history in survival is less clear. The aim of this study was to investigate the association between family history and cancer survival for the common cancers in Sweden. Using the Swedish population-based registers, patients diagnosed with the most common cancers were followed for cancer-specific death during 1991-2010. We used multivariate proportional hazards (Cox) regression models to contrast the survival of patients with a family history of cancer (individuals whose parent or sibling had a concordant cancer) to the survival of patients without a family history. Family history of cancer had a modest protective effect on survival for breast cancer (hazard ratio (HR) = 0.88, 95% confidence interval (95% CI) = 0.81 to 0.96) and prostate cancer (HR = 0.82, 95% CI = 0.75 to 0.90). In contrast, family history of cancer was associated with worse survival for nervous system cancers (HR = 1.24, 95% CI = 1.05 to 1.47) and ovarian cancer (HR = 1.20, 95% CI = 1.01 to 1.43). Furthermore, the poorer survival for ovarian cancer was consistent with a higher FIGO stage and a greater proportion of more aggressive tumors of the serous type. The better survival for patients with a family history of breast and prostate cancer may be due to medical surveillance of family members. The poor survival for ovarian cancer patients with an affected mother or sister is multifactorial, suggesting that these cancers are more aggressive than their sporadic counterparts.

Tidskriftsartikel (refereegranskat)abstract
- Background: Polygenic risk profiles computed from multiple common susceptibility alleles for breast cancer have been shown to identify women at different levels of breast cancer risk. We evaluated whether this genetic risk stratification can also be applied to discriminate between screen-detected and interval cancers, which are usually associated with clinicopathological and survival differences. Patients and methods: A 77-SNP polygenic risk score (PRS) was constructed for breast cancer overall and by estrogen-receptor (ER) status. PRS was inspected as a continuous (per standard deviation increment) variable in a case-only design. Modification of the PRS by mammographic density was evaluated by fitting an additional interaction term. Results: PRS weighted by breast cancer overall estimates was found to be differentially associated with 1,865 screen-detected and 782 interval cancers in the LIBRO-1 study (age-adjusted ORperSD [95% confidence interval]=0.91 [0.83-0.99], p=0.023). The association was found to be more significant for PRS weighted by ER-positive breast cancer estimates (ORperSD=0.90 [0.82-0.98], p=0.011). This result was corroborated by two independent studies (combined ORperSD=0.87 [0.76-1.00], p=0.058) with no evidence of heterogeneity. When enriched for “true” interval cancers among nondense breasts, the difference in the association with PRS in screen-detected and interval cancers became more pronounced (ORperSD=0.74 [0.62-0.89], p=0.001), with a significant interaction effect between PRS and mammographic density (pinteraction=0.017). Conclusion: To our knowledge, this is the first report looking into the genetic differences between screendetected and interval cancers. It is an affirmation that the two types of breast cancer may have unique underlying biology.

Born Small for Gestational Age : Beyond Size at Birth
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Children born small for gestational age (SGA) run increased risk of perinatal morbidity and mortality, but also of long-term health impairment. Risks on long term may vary depending on postnatal growth patterns. The overall aim of the thesis was to gain further knowledge about long-term consequences of being born SGA, as well as the impact of perinatal exposures on postnatal growth patterns. The thesis is based on four register-based cohort studies.In paper I, risk of chronic hypertension was assessed in 731,008 first-time mothers. Perinatal exposure to pre-eclampsia, being born SGA and preterm were all independently associated with increased risk of chronic hypertension. The risk was further enhanced after combined exposure. The strongest association was seen in combinations including pre-eclampsia.In paper II, risk of poor school performance at time of graduation from compulsory school was assessed in 1,088,980 children born SGA at term. Being born SGA was associated with increased risk of poor school performance, following a dose-response pattern with increased risk even for birthweight for gestational age (GA) –1.01 to –2 SD. Boys with short adult stature were associated with higher risk of poor school performance than those with non-short stature.In paper III, differences in postnatal growth patterns depending on SGA status and maternal smoking habits were assessed in 32,493 children. Children born SGA with smoking mothers had a more rapid catch-up growth than those with non-smoking mothers. Compared with children born appropriate for GA (AGA) with non-smoking mothers, only children born SGA with non-smoking mothers were associated with increased risk of short stature at 1.5 and 5 years.In paper IV, differences in postnatal growth patterns until age five years, depending on SGA status and GA at birth, were assessed in 41,669 children born between 32-40 gestational weeks. Being born SGA and moderate to late preterm was associated with shorter stature and lower BMI, compared with being born AGA at term. SGA status had greater impact on growth and body proportions than GA at birth.In conclusion, children born SGA are at higher risk of chronic hypertension and cognitive impairment than children born AGA. Postnatal growth patterns vary in children born SGA, depending on intrauterine exposure to smoking and GA at birth. This may modify risks of long-term health impairment.
