- A growing body of correlational studies suggests that sex hormones such as those contained in, or affected by, oral contraceptives (OCs) may impact economic behavior. However, despite widespread use of OCs among women in Western countries, little is known about their potential behavioral effects. The present study investigates whether OCs causally influence economic preferences. We randomly allocate 340 women aged 18–35 to three months of a widely used OC or placebo treatment. At the end of treatment, we conduct an economic experiment measuring altruism, financial risk taking, and willingness to compete. The statistical power is 80% to detect an effect size equal to a Cohen’s d of 0.30 at the 5% level. We find no significant effects of OCs on any of the measured preferences, indicating that this widely used OC treatment, commonly used throughout the world, does not significantly affect the measured economic preferences. Further, we find no relation between menstrual cycle phase and economic preferences in the placebo group.

- Medicine and healthcare are undergoing profound changes. Whole-genome sequencing and high-resolution imaging technologies are key drivers of this rapid and crucial transformation. Technological innovation combined with automation and miniaturization has triggered an explosion in data production that will soon reach exabyte proportions. How are we going to deal with this exponential increase in data production? The potential of "big data" for improving health is enormous but, at the same time, we face a wide range of challenges to overcome urgently. Europe is very proud of its cultural diversity; however, exploitation of the data made available through advances in genomic medicine, imaging, and a wide range of mobile health applications or connected devices is hampered by numerous historical, technical, legal, and political barriers. European health systems and databases are diverse and fragmented. There is a lack of harmonization of data formats, processing, analysis, and data transfer, which leads to incompatibilities and lost opportunities. Legal frameworks for data sharing are evolving. Clinicians, researchers, and citizens need improved methods, tools, and training to generate, analyze, and query data effectively. Addressing these barriers will contribute to creating the European Single Market for health, which will improve health arid healthcare for all Europearis.

Combined Oral Contraceptives and Sexual Function in Women-a Double-Blind, Randomized, Placebo-Controlled Trial
- 2016

- Context: There is a lack of knowledge about how oral contraceptives may affect sexual function.Objective: To determine whether there is a causal effect of oral contraceptives on sexuality. We hypothesized that a widely used pill impairs sexuality.Design: A double-blind, randomized, placebo-controlled trial. Enrollment began in February 2012 and was completed in August 2015.Setting: Karolinska University Hospital, Stockholm, Sweden.Participants: A total of 340 healthy women, aged 18-35 years, were randomized to treatment, and 332 completed the study.Interventions: A combined oral contraceptive (150 mu g levonorgestrel and 30 mu g ethinylestradiol) or placebo for 3 months of treatment.Main Outcome Measures: The primary outcome was the aggregate score on the Profile of Female Sexual Function (PFSF). Secondary outcomes were the seven domains of the PFSF, the Sexual Activity Log, and the Personal Distress Scale.Results: Overall sexual function was similar in women in the oral contraceptive and placebo groups. The PFSF domains desire (-4.4; 95% confidence interval [CI], -8.49 to -0.38; P =.032), arousal (-5.1; 95% CI, -9.63 to -0.48; P=.030), and pleasure (-5.1; 95% CI, -9.97 to -0.32; P =.036) were significantly reduced in comparison to placebo, whereas orgasm, concern, responsiveness, and self-image were similar between groups. The mean frequency of satisfying sexual episodes and personal distress were also similar between groups.Conclusions: This study shows no negative impact of a levonorgestrel-containing oral contraceptive on overall sexual function, although three of seven sexual function domains were adversely affected.

- Many studies report on the association between 2D:4D, a putative marker for prenatal testosterone exposure, and economic preferences. However, most of these studies have limited sample sizes and test multiple hypotheses (without preregistration). In this study we mainly replicate the common specifications found in the literature for the association between the 2D:4D ratio and risk taking, the willingness to compete, and dictator game giving separately. In a sample of 330 women we find no robust associations between any of these economic preferences and 2D:4D. We find no evidence of an effect for sixteen of the eighteen total regressions we run. The two regression specifications which are significant have not previously been reported and the associations are not in the expected direction, and therefore they are unlikely to represent a real effect.

- Human genomics is undergoing a step change from being a predominantly research-driven activity to one driven through health care as many countries in Europe now have nascent precision medicine programmes. To maximize the value of the genomic data generated, these data will need to be shared between institutions and across countries. In recognition of this challenge, 21 European countries recently signed a declaration to transnationally share data on at least 1 million human genomes by 2022. In this Roadmap, we identify the challenges of data sharing across borders and demonstrate that European research infrastructures are well-positioned to support the rapid implementation of widespread genomic data access.

Human hantavirus infection elicits pronounced redistribution of mononuclear phagocytes in peripheral blood and airways

- Hantaviruses infect humans via inhalation of virus-contaminated rodent excreta. Infection can cause severe disease with up to 40% mortality depending on the viral strain. The virus primarily targets the vascular endothelium without direct cytopathic effects. Instead, exaggerated immune responses may inadvertently contribute to disease development. Mononuclear phagocytes (MNPs), including monocytes and dendritic cells (DCs), orchestrate the adaptive immune responses. Since hantaviruses are transmitted via inhalation, studying immunological events in the airways is of importance to understand the processes leading to immunopathogenesis. Here, we studied 17 patients infected with Puumala virus that causes a mild form of hemorrhagic fever with renal syndrome (HFRS). Bronchial biopsies as well as longitudinal blood draws were obtained from the patients. During the acute stage of disease, a significant influx of MNPs expressing HLA-DR, CD11c or CD123 was detected in the patients' bronchial tissue. In parallel, absolute numbers of MNPs were dramatically reduced in peripheral blood, coinciding with viremia. Expression of CCR7 on the remaining MNPs in blood suggested migration to peripheral and/or lymphoid tissues. Numbers of MNPs in blood subsequently normalized during the convalescent phase of the disease when viral RNA was no longer detectable in plasma. Finally, we exposed blood MNPs in vitro to Puumala virus, and demonstrated an induction of CCR7 expression on MNPs. In conclusion, the present study shows a marked redistribution of blood MNPs to the airways during acute hantavirus disease, a process that may underlie the local immune activation and contribute to immunopathogenesis in hantavirus-infected patients.

Tidskriftsartikel (refereegranskat)abstract
- There is an urgent need to improve the infrastructure supporting the reuse of scholarly data. A diverse set of stakeholders-representing academia, industry, funding agencies, and scholarly publishers-have come together to design and jointly endorse a concise and measureable set of principles that we refer to as the FAIR Data Principles. The intent is that these may act as a guideline for those wishing to enhance the reusability of their data holdings. Distinct from peer initiatives that focus on the human scholar, the FAIR Principles put specific emphasis on enhancing the ability of machines to automatically find and use the data, in addition to supporting its reuse by individuals. This Comment is the first formal publication of the FAIR Principles, and includes the rationale behind them, and some exemplar implementations in the community.
