Women with fair phenotypes seem to confer a survival advantage in a low UV milieu. A nested matched case control study
- 2020

In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 15:1
-
Journal article (peer-reviewed)abstract
- 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.

Women with a predisposition for diabetes have an increased risk of pregnancy complications, especially in combination with pregestational overweight
- 2020
-
In: BMC Pregnancy and Childbirth. - : Springer Science and Business Media LLC. - 1471-2393. ; 20
-
Journal article (peer-reviewed)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
-
In: Frontiers in Oncology. - : Frontiers Media SA. - 2234-943X. ; 10
-
Research review (peer-reviewed)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
-
Reports (other academic/artistic)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.

Journal article (peer-reviewed)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.

Journal article (peer-reviewed)abstract
- Checkpoint blockade therapies that reactivate tumour-associated T cells can induce durable tumour control and result in the long-term survival of patients with advanced cancers1. Current predictive biomarkers for therapy response include high levels of intratumour immunological activity, a high tumour mutational burden and specific characteristics of the gut microbiota2,3. Although the role of T cells in antitumour responses has thoroughly been studied, other immune cells remain insufficiently explored. Here we use clinical samples of metastatic melanomas to investigate the role of B cells in antitumour responses, and find that the co-occurrence of tumour-associated CD8+ T cells and CD20+ B cells is associated with improved survival, independently of other clinical variables. Immunofluorescence staining of CXCR5 and CXCL13 in combination with CD20 reveals the formation of tertiary lymphoid structures in these CD8+CD20+ tumours. We derived a gene signature associated with tertiary lymphoid structures, which predicted clinical outcomes in cohorts of patients treated with immune checkpoint blockade. Furthermore, B-cell-rich tumours were accompanied by increased levels of TCF7+ naive and/or memory T cells. This was corroborated by digital spatial-profiling data, in which T cells in tumours without tertiary lymphoid structures had a dysfunctional molecular phenotype. Our results indicate that tertiary lymphoid structures have a key role in the immune microenvironment in melanoma, by conferring distinct T cell phenotypes. Therapeutic strategies to induce the formation of tertiary lymphoid structures should be explored to improve responses to cancer immunotherapy.

The Role of PTEN Loss in Immune Escape, Melanoma Prognosis and Therapy Response
- 2020
-
In: Cancers. - : MDPI AG. - 2072-6694. ; 12:3
-
Journal article (peer-reviewed)abstract
- Checkpoint blockade therapies have changed the clinical management of metastatic melanoma patients considerably, showing survival benefits. Despite the clinical success, not all patients respond to treatment or they develop resistance. Although there are several treatment predictive biomarkers, understanding therapy resistance and the mechanisms of tumor immune evasion is crucial to increase the frequency of patients benefiting from treatment. The PTEN gene is thought to promote immune evasion and is frequently mutated in cancer and melanoma. Another feature of melanoma tumors that may affect the capacity of escaping T-cell recognition is melanoma cell dedifferentiation characterized by decreased expression of the microphtalmia-associated transcription factor (MITF) gene. In this study, we have explored the role of PTEN in prognosis, therapy response, and immune escape in the context of MITF expression using immunostaining and genomic data from a large cohort of metastatic melanoma. We confirmed in our cohort that PTEN alterations promote immune evasion highlighted by decreased frequency of T-cell infiltration in such tumors, resulting in a worse patient survival. More importantly, our results suggest that dedifferentiated PTEN negative melanoma tumors have poor patient outcome, no T-cell infiltration, and transcriptional properties rendering them resistant to targeted- and immuno-therapy.
