Osteoarthritis endotype discovery via clustering of biochemical marker data

Objectives Osteoarthritis (OA) patient stratification is an important challenge to design tailored treatments and drive drug development. Biochemical markers reflecting joint tissue turnover were measured in the IMI-APPROACH cohort at baseline and analysed using a machine learning approach in order to study OA-dominant phenotypes driven by the endotype-related clusters and discover the driving fea

Prognostic Significance of GPR55 mRNA Expression in Colon Cancer

G protein-coupled receptor 55 (GPR55) probably plays a role in innate immunity and tumor immunosurveillance through its effect on immune cells, such as T cells and NK cells. In this study, the prognostic value of GPR55 in colon cancer (CC) was investigated. mRNA expression levels of GPR55 were determined in 382 regional lymph nodes of 121 CC patients with 12 years observation time after curative s

A healthy dietary metabolic signature is associated with a lower risk for type 2 diabetes and coronary artery disease

Background: The global burden of cardiovascular disease and type 2 diabetes could be decreased by improving dietary factors, but identification of groups suitable for interventional approaches can be difficult. Reporting of dietary intake is prone to errors, and measuring of metabolites has shown promise in determining habitual dietary intake. Our aim is to create a metabolic signature that is ass

PD‐L1 Expression in Non‐Small Cell Lung Cancer Specimens : Association with Clinicopathological Factors and Molecular Alterations

Immune checkpoint inhibitors (ICI) targeting programmed cell death‐1 or its ligand (PD‐ L1) have improved outcomes in non‐small cell lung cancer (NSCLC). High tumor PD‐L1 expression, detected by immunohistochemistry (IHC) typically on formalin‐fixed paraffin‐embedded (FFPE) histological specimens, is linked to better response. Following our previous investigation on PD‐L1 in cytological samples, t

A Starch-and Sucrose-Reduced Diet in Irritable Bowel Syndrome Leads to Lower Circulating Levels of PAI-1 and Visfatin : A Randomized Controlled Study

Irritable bowel syndrome (IBS) is characterized by gastrointestinal symptoms. Overweight and increased risk of metabolic syndromes/diabetes are observed in IBS, conditions associated with plasminogen activator inhibitor-1 (PAI-1) and visfatin. The aim of this study was to measure blood levels of AXIN1, cholecystokinin (CCK), enkephalin, ghrelin, neuropeptide Y (NPY), PAI-1, and visfatin before and

Association between sensorimotor function and visual assessment of postural orientation in patients with ACL injury

Objectives: To investigate the association between sensorimotor function and visual assessment of postural orientation during execution of weight-bearing activities in patients with anterior cruciate ligament reconstruction (ACLR). Design: Cross-sectional study. Setting: Laboratory. Participants: Fifty-two individuals (23 women and 29 men, mean (SD) age 26.5 (6.4)) approximately 7 months after ACL

Subjectively safe cycling infrastructure : New insights for urban designs

Transportation infrastructure that accommodates the needs of active mode users is an essential element of sustainable and just urban mobility transitions. Safety is a major factor influencing bicyclist behavior, and understanding how safety is perceived by traffic participants can support urban designs that will attract greater shares of active travelers. This paper evaluates the stated preference

Scheimpflug lidar range profiling of bee activity patterns and spatial distributions

Background: Recent declines of honeybees and simplifications of wild bee communities, at least partly attributed to changes of agricultural landscapes, have worried both the public and the scientific community. To understand how wild and managed bees respond to landscape structure it is essential to investigate their spatial use of foraging habitats. However, such studies are challenging since the

Self-consistent modelling of the Milky Way's nuclear stellar disc

The nuclear stellar disc (NSD) is a flattened high-density stellar structure that dominates the gravitational field of the Milky Way at Galactocentric radius $30\, {\rm pc}\lesssim R\lesssim 300\, {\rm pc}$. We construct axisymmetric self-consistent equilibrium dynamical models of the NSD in which the distribution function is an analytic function of the action variables. We fit the models to the n

Miocene Climate and Habitat Change Drove Diversification in Bicyclus, Africa's Largest Radiation of Satyrine Butterflies

Compared to other regions, the drivers of diversification in Africa are poorly understood. We studied a radiation of insects with over 100 species occurring in a wide range of habitats across the Afrotropics to investigate the fundamental evolutionary processes and geological events that generate and maintain patterns of species richness on the continent. By investigating the evolutionary history

Bird populations most exposed to climate change are less sensitive to climatic variation

The phenology of many species shows strong sensitivity to climate change; however, with few large scale intra-specific studies it is unclear how such sensitivity varies over a species’ range. We document large intra-specific variation in phenological sensitivity to temperature using laying date information from 67 populations of two co-familial European songbirds, the great tit (Parus major) and b

SYSTEMATIC LITERATURE REVIEW: DATA STANDARDIZATION IN HEALTH INFORMATION SYSTEMS

Digitalization within the healthcare sector has resulted in the accumulation of vast amounts of data that can be utilized towards the improvement of health outcomes. Meaningful use of such data, however, requires that it is standardized. Standardization plays a key role in providing a universal language for data that is exchanged through different health systems. Through a systematic literature re

Serotonergic system in vivo with [11C]DASB PET scans in GTP-cyclohydrolase deficient dopa-responsive dystonia patients

GTP-cyclohydrolase deficiency in dopa-responsive dystonia (DRD) patients impairs the biosynthesis of dopamine, but also of serotonin. The high prevalence of non-motor symptoms suggests involvement of the serotonergic pathway. Our study aimed to investigate the serotonergic system in vivo in the brain of`DRD patients and correlate this to (non-)motor symptoms. Dynamic [11C]DASB PET scans, a marker

Association of β-Amyloid Accumulation with Executive Function in Adults with Unimpaired Cognition

Background and Objectives The neuropathologic changes underlying Alzheimer disease (AD) start before overt cognitive symptoms arise, but it is not well-known how they relate to the first subtle cognitive changes. The objective for this study was to examine the independent associations of the AD hallmarks β-amyloid (Aβ), tau, and neurodegeneration with different cognitive domains in cognitively uni

Structural equation modeling reveals decoupling of ecological and self-perceived outcomes in a garden box social-ecological system

It is well known that green urban commons enhance mental and physical well-being and improve local biodiversity. We aim to investigate how these outcomes are related in an urban system and which variables are associated with better outcomes. We model the outcomes of an urban common—box gardening—by applying the Social-Ecological Systems (SES) framework. We expand the SES framework by analyzing it

Evidence for postnatal neurogenesis in the human amygdala

The human amygdala is involved in processing of memory, decision-making, and emotional responses. Previous studies suggested that the amygdala may represent a neurogenic niche in mammals. By combining two distinct methodological approaches, lipofuscin quantification and 14C-based retrospective birth dating of neurons, along with mathematical modelling, we here explored whether postnatal neurogenes

A C-H Activation Approach to the Tricyclic Core of Glionitrin A and B

Synthesis of diketopiperazines has been of long-standing interest in both natural product synthesis and medicinal chemistry. Here, we present an operationally convenient and efficient approach to the fused indoline-diketopiperazine tricyclic core of glionitrin A/B and related structures using a Pd-catalyzed C-H activation reaction to form the indoline five-membered ring. Exploratory work aimed at

Sure I can code (But do I want to?). Why boys’ and girls’ programming beliefs differ and the effects of mandatory programming education

In our increasingly digitalized society, it is important to have a grasp of basic programming and therefore, programming was recently made mandatory in Swedish schools. We investigated how the mandatory programming education affects self-efficacy and interest in programming in a sample of 12-year-old children (N = 373). Data was collected at the start of the school year, directly after the educati

Stress fractures of the femoral neck in adults : an observational study on epidemiology, treatment, and reoperations from the Swedish Fracture Register

Background and purpose — Stress fractures of the femoral neck (sFNFs) are uncommon injuries. Studies on sFNFs are rare. We describe the demographics, classification, treat-ment, reoperation rates, and mortality in a cohort of sFNF patients from the Swedish Fracture Register (SFR). Patients and methods — We included 146 patients ≥ 18 years of age with an sFNF registered in the SFR between 2011 and
