Background Drug use disorder (DUD) clusters in families due partly to shared environment, including sibling influences. Low academic achievement (AA) in adolescence increases DUD risk. This study examined whether low AA in an older sibling causally increases DUD risk in younger siblings. Methods We studied all Swedish full sibling pairs (n = 309,666) born 1972–1985 and ≤ 5 years apart. Older sibli

In recent years, countries, regions, municipalities and the EU Commission have introduced a significant number of innovation policy initiatives under the banner of ‘missions’, ‘societal challenges’, sustainability, and ‘transformation’, or systemic change. In parallel, there has been a rapidly growing body of literature seeking to analyze or assess these real-world manifestations of attempts to pi

A key challenge in developing sustainable cities is establishing circular infrastructure systems. Decentralised urban water management solutions (DUWMS) are a case in point: Innovative DUWMS that allow recycling the water, heat, energy, or nutrients contained in wastewater locally are currently emerging in cities around the world. These systems could significantly enhance cities’ water resilience

The traditional approach to quantum parameter estimation focuses on the quantum state, deriving fundamental bounds on precision through the quantum Fisher information. In most experimental settings, however, performing arbitrary quantum measurements is highly unfeasible. In open quantum systems, an alternative approach to metrology involves the measurement of stochastic currents flowing from the s

As the need to limit the effect of climate change gets stronger, the transition to sustainable energy solutions becomes very important. Solar thermal energy and green hydrogen production represent two quite promising sustainable fields towards decarbonizing industrial processes and energy sectors. This thesis presents an extensive simulation and performance analysis of a solar thermal energy syste

This article presents the analysis of a large survey on file-sharing that was conducted in April 2011 with over 75,000 respondents from all over the world. The study, also known as The Research Bay, due to that it was conducted in collaboration with the infamous BitTorrent site The Pirate Bay, by the Cybernorms research group. The aim of the online study of The Pirate Bay community has been to des

Detailed phenotyping is required to deepen our understanding of the biological mechanisms behind genetic associations. In addition, the impact of potentially modifiable risk factors on disease requires analytical frameworks that allow causal inference. Here, we discuss the characteristics of Recall-by-Genotype (RbG) as a study design aimed at addressing both these needs. We describe two broad scen

Type 2 diabetes (T2D) is widespread, affecting the health of hundreds of millions worldwide. The disease results from the complex interplay of lifestyle factors acting on a backdrop of inherited DNA risk variants. Detecting and understanding biomarkers, whether genotypes or other downstream biological features that dictate a person's phenotypic response to different lifestyle exposures, may have t

In this issue of Cell Stem Cell, Peruzzotti-Jametti et al. (2018) demonstrate how neural stem cells, transplanted in a mouse model of multiple sclerosis, respond to extracellular succinate and modulate neuroinflammation by releasing anti-inflammatory prostaglandin E2 and scavenging succinate. This mechanism reduces CNS damage and ameliorates motor impairment. In this issue of Cell Stem Cell, Peruz

Recent genetic studies have identified alleles associated with opposite effects on adiposity and risk of type 2 diabetes. We aimed to identify more of these variants and test the hypothesis that such favorable adiposity alleles are associated with higher subcutaneous fat and lower ectopic fat. We combined MRI data with genome-wide association studies of body fat percentage (%) and metabolic traits

Objective: Glucose dysregulation is an independent risk factor for cardiovascular and neurodegenerative disease development through synaptic dysfunction resulting in cognitive decline. The aim of this study was to study the interplay between impaired glycaemic metabolism (hyperglycaemia and insulin resistance), cardiac stress (cardiac troponin T and N-terminal brain natriuretic peptide) and execut

Aims: The present study aimed to investigate if set thresholds in the Swedish heat-wave warning system are valid for all parts of Sweden and if the heat-wave warning system captures a potential increase in all-cause mortality and coronary heart disease (CHD) mortality. An additional aim was to investigate whether neighbourhood deprivation modifies the relationship between heat waves and mortality.

Cities are key actors in reducing both the causes of climate change (mitigation) and its impact (adaptation), and many have developed separate mitigation and adaptation strategies and measures. However, in order to maximize outcomes, both scholars and practitioners are increasingly calling for more integrated and synergetic approaches. Unfortunately, related research remains scarce and fragmented,

The prevalence and incidence of doctor-diagnosed Dupuytren's disease in the general population is unknown. From the healthcare register for Skåne region (population 1.3 million) in southern Sweden, we identified all residents aged 3/420 years (on 31 December 2013), who 1998 to 2013 had consulted a doctor and received the diagnosis Dupuytren's disease (International Classification of Diseases 10th

Glatiramer acetate is used therapeutically in multiple sclerosis but also known for adverse effects including elevated coronary artery disease (CAD) risk. The mechanisms underlying the cardiovascular side effects of the medication are unclear. Here, we made use of the chromosomal variation in the genes that are known to be affected by glatiramer treatment. Focusing on genes and gene products repor

Aims/hypothesis: There is an extensive body of literature suggesting the involvement of multiple loci in regulating the action of metformin; most findings lack replication, without which distinguishing true-positive from false-positive findings is difficult. To address this, we undertook evidence-based, multiple data integration to determine the validity of published evidence. Methods: We (1) buil

Behandlar gipsavgjutningarnas ställning och roll i konstutbildningen och på konstmuseerna från 1700-talet till 1914.

Aims: Subclinical systemic inflammation may contribute to the development of type 2 diabetes, but its association with early progression of glycaemic deterioration in persons without diabetes has not been fully investigated. Our primary aim was to assess longitudinal associations of changes in pro-inflammatory (leukocytes, high-sensitivity C-reactive protein (hsCRP)) and anti-inflammatory (adipone

The detailed characterization of human biology and behaviors is now possible at scale owing to innovations in biomarkers, bioimaging, and wearable technologies; "big data" from electronic medical records, health insurance databases, and other platforms becoming increasingly accessible; and rapidly evolving computational power and bioinformatics methods. Collectively, these advances are creating un
