- Background Sun exposure in combination with skin pigmentation is the main determinant for vitamin D status. Human skin color seems to be adapted and optimized for regional sun ultraviolet (UV) intensity. However, we do not know if fair, UV-sensitive skin is a survival advantage in regions with low UV radiation. Methods A population-based nested case-control study of 29,518 Caucasian women, ages 25 to 64 years from Southern Sweden who responded to a questionnaire regarding risk-factors for malignant melanoma in 1990 and followed for 25 years. For each fair woman, defined as having red hair or freckles (n = 11,993), a control was randomly selected from all non-fair women from within the cohort of similar age, smoking habits, education, marital status, income, and comorbidity, i.e., 11,993 pairs. The main outcome was the difference in allcause mortality between fair and non-fair women in a low UV milieu, defined as living in Sweden and having low-to-moderate sun exposure habits. Secondary outcomes were mortality by sun exposure, and among those non-overweight. Results In a low UV milieu, fair women were at a significantly lower all-cause mortality risk as compared to non-fair women (log rank test p = 0.04) with an 8% lower all-cause mortality rate (hazard ratio [HR] = 0.92, 95% CI 0.84-1.0), including a 59% greater risk of dying from skin cancer among fair women (HR 1.59, 95% CI 1.26-2.0). Thus, it seem that the beneficial health effect from low skin coloration outweigh the risk of skin cancer at high latitudes. Conclusion In a region with low UV milieu, evolution seems to improve all-cause survival by selecting a fair skin phenotype, i.e., comprising fair women with a survival advantage.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Overweight and gestational diabetes are risk factors for pregnancy complications. We hypothesized that the metabolic impact of overweight on pregnancy outcome, would be different if it was combined with a predisposition for diabetes. The aim of this study was to compare the outcome of pregnancies in women with diabetes diagnosed later in life, to the outcome of pregnancies of women who did not develop diabetes. METHODS: Women in a population-based cohort who also were registered in the Swedish Medical Birth Registry (n = 4738) were included. A predisposition for diabetes (GDM or diabetes after pregnancy) was found in 455 pregnancies. The number of pregnancies with maternal BMI ≥ 25 kg/m2 and without diabetes were 2466, and in 10,405 pregnancies the mother had a BMI < 25 kg/m2 without diabetes at any time. Maternal BMI, gestational length, gestational weight gain, frequency of caesarean section, infant birth weight, frequency of large for gestational age (LGA) and Apgar score were retrospectively compared. RESULTS: Pregnancies with normal maternal BMI ≤25 kg/m2, with predisposition for diabetes had a higher frequency of LGA (11.6% vs. 2.9%; p < 0.001), a higher frequency of macrosomia (28.6% vs. 17.6%; p < 0.001), and a shorter gestational length (39.7 vs. 40 weeks; p = 0.08) when compared to pregnancies in women without a predisposition for diabetes. In addition, pregnancies with both maternal predisposition for diabetes and BMI ≥ 25 kg/m2 there was a higher frequency of LGA (23.3% vs. 7.1%; p < 0.001), caesarean section (24.0% vs. 14.9%, p = 0.031) compared to pregnancies in women who were only overweight. A predisposition for diabetes significantly increases the risk of macrosomia (OR1.5; 95% CI 1.07-2.15; p = 0.02). CONCLUSIONS: In pregnancy, there is an increased frequency of LGA, macrosomia and caesarean section if the woman has a predisposition for diabetes. The frequency of overweight young women is increasing, and it is urgent to identify pregnant women with a predisposition to diabetes. How to distinguish the women with the highest risk for adverse pregnancy outcome and the highest risk of future disease, remains to be studied.

The Menstrual Cycle and Risk of Breast Cancer : A Review
- 2020
-
Ingår i: Frontiers in Oncology. - : Frontiers Media SA. - 2234-943X. ; 10
-
Forskningsöversikt (refereegranskat)abstract
- Cyclic hormonal stimulation of the breast tissue plays a significant role in breast carcinogenesis. Current risk factor models do not include direct measures of cycle characteristics although the effects of possible surrogates of cycle activity such as age at menarche and menopause, parity, and nursing time have been investigated. Future risk models should also include menstrual cycle length, regularity, number of cycles before first full-term pregnancy, and life-time number of cycles. New risk factor models for pre- and postmenopausal breast cancer are proposed here. Furthermore, there is a need for more long-term, prospective studies investigating menstrual cycle characteristics as data currently available are primarily retrospective and collected at one time-point only.

GET-tjänsten och infrastrukturen för distribution av geodata till universitet och högskolor
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Geodata Extraction Tool (GET) är en tjänst för att tillgängliggöra myndigheters digitala geografiska data till universitet och högskolor i Sverige. GET-tjänsten startades 2012 för att tillgodose studenters och forskares behov av att enkelt och kostnadsfritt kunna få tillgång till Lantmäteriets digitala geodata som annars var avgiftsbelagda. Tjänsten har senare utvidgats med geodata från andra myndigheter, och idag kan förutom det mesta av Lantmäteriets geografiska data, även en del data från SGU, SCB och Sjöfartsverket nås via GET. Tjänsten är utvecklad av, och sköts av, Sveriges lantbruksuniversitet (SLU). I denna rapport sammanfattas tillkomsten av GET, vilka avtal som ligger till grund för tjänsten, hur man använder den och vilka data som distribueras via denna samverkan mellan berörda myndigheter. Dessutom redovisas senaste årets statistik för nedladdade geodatamängder samt resultaten från en användarenkät 2019. Rapporten avslutas med en framåtblick.

- Background: Many patients undergo percutaneous coronary intervention (PCI) without the use of non-invasive stress testing prior to treatment. The aim of this study was to determine the potential added value of guiding revascularization by quantitative assessment of myocardial perfusion prior to intervention. Methods and Results: Thirty-three patients (10 females) with suspected or established CAD who had been referred for a clinical coronary angiography (CA) with possibility for PCI were included. Adenosine stress and rest 13N-NH3 PET, cardiac magnetic resonance (CMR), and cardiopulmonary exercise test were performed 4 ± 3 weeks before and 5 ± 1 months after CA. The angiographer was blinded to the PET and CMR results. Myocardial flow reserve (MFR) < 2.0 by PET was considered abnormal. A PCI was performed in 19/33 patients. In 41% (11/27) of the revascularized vessel territories, a normal regional MFR was found prior to the PCI and no improvement in MFR was found at follow-up (P = 0.9). However, vessel territories with regional MFR < 2.0 at baseline improved significantly after PCI (P = 0.003). Of the 14 patients not undergoing PCI, four had MFR < 2.0 in one or more coronary territories. Conclusion: Assessment of quantitative myocardial perfusion prior to revascularization could lead to more appropriate use of CA when managing patients with stable CAD.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: In Sweden, a Traceback approach, i.e., a retrospective genetic outreach activity, among cancer patients is not normally used in clinical practice. In this pilot study, we wanted to evaluate a Traceback strategy for possible future clinical implementation and investigate why not all women with early-onset breast cancer underwent genetic testing when they were first diagnosed. Methods: Out of all women (n = 409) diagnosed with breast cancer at ≤ 35 years in Southern Sweden between 2000 and 2017, 63 had not previously been tested. These women were offered an analysis of the genes BRCA1, BRCA2, PALB2, CHEK2, and ATM through a standardized letter. Subsequently, women with normal test results were informed through a letter and carriers of pathogenic variants were contacted through a telephone call and offered in-person genetic counseling. All tested women were asked to complete a follow-up questionnaire regarding previously not having attended genetic counseling and testing and their experiences of the current retrospective approach. Results: Out of the invited women, 29 (46%) underwent genetic testing and 27 (43%) answered the questionnaire. Pathogenic variants were identified in BRCA1 (n = 2), CHEK2 (n = 1), and ATM (n = 1). The main reason for previously not having undergone genetic testing was not having received any information from their physicians. Most study participants were satisfied with both written pre- and post-test information. Conclusion: The process with retrospective identification, written pre-test information, and genetic testing, followed by in-person counseling for carriers of pathogenic variants only, was well accepted. This has implications for future Traceback implementation programs.

Tidskriftsartikel (refereegranskat)abstract
- Swedish national breast cancer guidelines recommend that all women diagnosed with breast cancer (BC) at the age of 35 years or younger should be referred to their regional oncogenetic clinic for genetic counseling and testing, regardless of family history of cancer. The main objective of this study was to evaluate whether place of residence at BC diagnosis and treating hospital were associated with the fact that not all BC patients diagnosed at ≤35 years in the southern part of Sweden have attended genetic counseling and testing. Between 2000 and 2013, 279 women in the South Swedish Health Care Region were diagnosed with BC at ≤35 years. Information regarding place of residence at BC diagnosis, treating hospital, time of registration and first meeting at the Oncogenetic Clinic in Lund, and genetic testing was collected. With a follow-up period until August 2018, 64% were registered at the clinic (60% underwent genetic testing) and 36% were not. BC patients from 2 counties and from rural settings with a population of <10,000 inhabitants were significantly less likely to be registered at the clinic. Our results suggest that place of residence at BC diagnosis and treating hospital were associated with the probability of referral for genetic counseling and testing for women diagnosed with BC at ≤35 years in the South Swedish Health Care Region. We propose, as a generalizable finding, that further educational and outreach activities within the health care system and the community may be needed to ensure that all women diagnosed with early-onset BC receive proper genetic counseling.

Tree species classification using Sentinel-2 imagery and Bayesian inference

Tidskriftsartikel (refereegranskat)abstract
- The increased temporal frequency of optical satellite data acquisitions provides a data stream that has the potential to improve land cover mapping, including mapping of tree species. However, for large area operational mapping, partial cloud cover and different image extents can pose challenges. Therefore, methods are needed to assimilate new images in a straightforward way without requiring a total spatial coverage for each new image. This study shows that Bayesian inference applied sequentially has the potential to solve this problem. To test Bayesian inference for tree species classification in the boreo-nemoral zone of southern Sweden, field data from the study area of Remningstorp (58°27′18.35″ N, 13°39′8.03″ E) were used. By updating class likelihood with an increasing number of combined Sentinel-2 images, a higher and more stable cross-validated overall accuracy was achieved. Based on a Mahalanobis distance, 23 images were automatically chosen from the period of 2016 to 2018 (from 142 images total). An overall accuracy of 87% (a Cohen’s kappa of 78.5%) was obtained for four tree species classes: Betula spp., Picea abies, Pinus sylvestris, and Quercus robur. This application of Bayesian inference in a boreo-nemoral forest suggests that it is a practical way to provide a high and stable classification accuracy. The method could be applied where data are not always complete for all areas. Furthermore, the method requires less reference data than if all images were used for classification simultaneously.
