Head-to-Head Comparison of Tau and Amyloid Positron Emission Tomography Visual Reads for Differential Diagnosis of Neurodegenerative Disorders : An International, Multicenter Study

Objective: We compared the accuracy of amyloid and [18F]Flortaucipir (FTP) tau positron emission tomography (PET) visual reads for distinguishing patients with mild cognitive impairment (MCI) or dementia with fluid biomarker support of Alzheimer's disease (AD). Methods: Participants with FTP-PET, amyloid-PET, and diagnosis of dementia-AD (n = 102), MCI-AD (n = 41), non-AD diseases (n = 76), and co

Acceptable performance of blood biomarker tests of amyloid pathology — recommendations from the Global CEO Initiative on Alzheimer’s Disease

Anti-amyloid treatments for early symptomatic Alzheimer disease have recently become clinically available in some countries, which has greatly increased the need for biomarker confirmation of amyloid pathology. Blood biomarker (BBM) tests for amyloid pathology are more acceptable, accessible and scalable than amyloid PET or cerebrospinal fluid (CSF) tests, but have highly variable levels of perfor

Belimumab concentration measurements using a homologous anti-idiotype immunoassay

Monitoring belimumab concentrations in patients can be a valuable tool for assessing treatment response and for personalizing drug doses. Various assay formats may be used to measure concentrations of therapeutic monoclonal antibodies. A particularly useful format involves the use of anti-idiotype monoclonal antibodies, selected to be highly specific to the antibody of interest. Here, we describe

Infection episodes and islet autoantibodies in children at increased risk for type 1 diabetes before and during the COVID-19 pandemic

Objectives: To determine the impact of the COVID-19 pandemic on the incidence rates of infection and islet autoimmunity in children at risk for type 1 diabetes. Methods: 1050 children aged 4 to 7 months with an elevated genetic risk for type 1 diabetes were recruited from Germany, Poland, Sweden, Belgium and the UK. Reported infection episodes and islet autoantibody development were monitored unti

Data-Driven Phenotyping of Presymptomatic Type 1 Diabetes Using Longitudinal Autoantibody Profiles

OBJECTIVE To characterize distinct islet autoantibody profiles preceding stage 3 type 1 diabetes RESEARCH DESIGN AND METHODS The T1DI (Type 1 Diabetes Intelligence) study combined data from 1,845 genetically susceptible prospectively observed children who were positive for at least one islet au-toantibody: insulin autoantibody (IAA), GAD antibody (GADA), or islet antigen 2 antibody (IA-2A). Using

Rationalizing polyp matching criteria in colon capsule endoscopy : an international expert consensus through RAND (modified DELPHI) process

Background: Colon capsule endoscopy (CCE) has gained momentum as an alternative modality for the investigation of the lower gastrointestinal tract. Of the few challenges that remain, the comparison and – eventually – matching of polyps at different timestamps leads to the potential for double reporting and can contribute to false-positive findings and inaccuracies. With the impending artificial in

Hypothermia After Cardiac Arrest in Large Animals (HACA-LA) : Study protocol of a randomized controlled experimental trial

Background: Induced hypothermia post-cardiac arrest is neuroprotective in animal experiments, but few high-quality studies have been performed in larger animals with human-like brains. The neuroprotective effect of postischemic hypothermia has recently been questioned in human trials. Our aim is to investigate whether hypothermia post-cardiac arrest confers a benefit compared to normothermia in la

Landscape context and wetland attributes influence wintering waterbirds in important bird and biodiversity areas : implications for conservation and management

Context: The intensification and expansion of human activities have caused profound changes in global wetlands and their associated aquatic bird communities. Understanding the mechanisms that drive the spatial assemblages of wetland birds is important for the development of effective conservation and management strategies. Objectives: The overall objective was to evaluate the influence of wetland

Directly-excited laser-induced thermal grating spectroscopy and thermometry with carbon dioxide vibrational transition

Laser-induced thermal grating spectroscopy (LITGS) has been proved for accurate thermometry and measurement of energy transfer processes in molecules. While electronic transitions are often used for excitation in previous LITGS works, here we report laser-induced thermal gratings formed by direct excitation of CO2 with an infrared (IR) laser at wavelength near 2 μm, with which high signal-to-noise

Machine-learned tuning of artificial Kitaev chains from tunneling spectroscopy measurements

We demonstrate reliable machine-learned tuning of quantum-dot-based artificial Kitaev chains to Majorana sweet spots, using the covariance matrix adaptation algorithm. We show that a loss function based on local tunneling spectroscopy features of a chain with two additional sensor dots added at its ends provides a reliable metric to navigate parameter space and find points where crossed Andreev re

Stoichiometry regulates rice straw-induced priming effect : The microbial life strategies

Straw and nutrients retained in soil are crucial for priming effect (PE) and consequently for soil organic matter (SOM) turnover. However, the mechanisms by which carbon (C), nitrogen (N), and phosphorus (P) and their stoichiometric ratios impact microbial communities and regulate the PE intensity remain controversial, particularly in the flooded rice soils. In this work, the PE dynamics and micro

Circular Industrial Transition. : Can the Green Industrial Policy Revival Support Circular Industrial Transition in Sweden?

The major driver of the climate and biodiversity crisis is our unsustainable production and consumption patterns, but the need to transition to a circular and resource- efficient economy has not been sufficiently addressed by policymakers. Policies supporting circular industrial transition are still rare, not the least in contrast with the recent momentum gained by green industrial policy in EU an

Spectator Matter in Collisions of Relativistic Deformed Nuclei

Abstract: The Abrasion–Ablation Monte Carlo for Colliders (AAMCC) model is used to study the characteristics of spectator matter in central collisions of relativistic 238U nuclei, which are sensitive to the mutual orientation and the degree of deformation of the colliding nuclei. It is shown that the multiplicity of spectator neutrons and their forward-backward asymmetry substantially depend on th

Controllers for Two-Coordinate Positioning of the UAV Auxiliary Video Camera

Despite the successes in the use of artificial intelligence systems for image analysis, in certain critical applications, the final decision-making should remain with the human operator. To facilitate the working conditions of an unmanned aerial vehicle (UAV) pilot during prolonged missions, an auxiliary narrow-angle video camera is installed on board the UAV. This camera can be positioned indepen

Health workers’ perspectives on the quality of maternal and newborn health care around the time of childbirth : Results of the Improving MAternal Newborn carE in the EURO Region (IMAgiNE EURO) project in 12 countries of the World Health Organization European Region

BACKGROUND: Health workers' (HWs') perspectives on the quality of maternal and newborn care (QMNC) are not routinely collected. In this cross-sectional study, we aimed to document HWs' perspectives on QMNC around childbirth in 12 World Health Organization (WHO) European countries.METHODS: HWs involved in maternal/neonatal care for at least one year between March 2020 and March 2023 answered an onl

Circular hubs : enablers for increasing reuse of construction products

The construction industry is ranked number one compared to other sectors when it comes to waste generated in the European Union. Reuse of products is a priority within the European Union to reduce the need for virgin materials and to reduce waste. Looking back at past practices, various approaches have been suggested to increase reuse of construction products, although these approaches have fallen

Excavations ON-AIR : How archaeological practice reshapes digital tools

The widespread diffusion and adoption of digital methods and tools into archaeological practice have deeply affected and often transformed how archaeologists interact with material culture, impacting also on the collaborative and reflective aspects of excavation methods. Moreover, these transformations in archaeological methods and practice, have also brought about advancements in data collection,
