Detection of Short Supraventricular Tachycardias in Single-lead ECGs Recorded Using a Handheld Device

Short supraventricular tachycardias (S-SVTs) have been associated with a higher risk of developing atrial fibrillation (AF). Hence, identification of participants with such arrhythmias may increase the yield of AF screening. However, the lower signal quality of ECGs recorded using handheld screening devices challenges the detection of S-SVT. In the present work, a new method for detection of S-SVT

Estimation of f-wave Dominant Frequency Using a Voting Scheme

Atrial fibrillation (AF) is the most common heart arrhythmia, characterized by the presence of fibrillatory waves (f-waves) in the ECG. We introduce a voting scheme to estimate the dominant atrial frequency (DAF) of f-waves. Methods: We analysed a subset of Holter recordings obtained from the University of Virginia AF Database. 100 Holter recordings with manually annotated AF events, resulting in

Standardization of serum creatinine is essential for accurate use of unbiased estimated GFR equations : Evidence from three cohorts matched on renal function

Background: Differences in the performance of estimated glomerular filtration rate (eGFR) equations have been attributed to the mathematical form of the equations and to differences between patient demographics and measurement methods. We evaluated differences in serum creatinine (SCr) and eGFR in cohorts matched for age, sex, body mass index (BMI) and measured GFR (mGFR). Methods: White North Ame

The COVID-19 pandemic and the timing of government response : A comparison of four Nordic countries March–June 2020

Objectives: The aim is to compare Sweden, Denmark, Finland and Norway regarding government response to the COVID-19 pandemic in mid-March–June 2020 using the Oxford Government Response Tracker. Study design: Descriptive longitudinal ecological study. Methods: Descriptive analysis of time series data. Results: Sweden displayed a far lower response index in March. By late April indexes were similar.

Trade and the transnational cleavage in European party politics

Theorists of the transnational cleavage, defined as a political reaction against European integration and immigration, also regularly conceptualise international trade preferences as a component of this contemporary societal divide. Yet empirical analyses of this cleavage focus on the former two topics, while trade and the transnational cleavage has not been systematically investigated. Making use

A phylogenomic perspective on the relationships of subfamilies in the family Geometridae (Lepidoptera)

Geometrid moths, the second largest radiation of Lepidoptera, have been the target of extensive phylogenetic studies. Those studies have flagged several problems in tree topology that have remained unanswered. We address three of those: (i) deep nodes of Geometridae (subfamilies Sterrhinae + Larentiinae, or Sterrhinae alone as sister to all other subfamilies), (ii) the taxonomic status of subfamil

An Overview of Plant-Based Protein Rich Products

Deleterious impact of animal meat production and consumption on environment and consumers health has developed interests for exploring relatively safer, healthier, and sustainable food sources. Promoting the production and consumption of plants as alternative to meat proteins do not merely conserve the ecosystem but also promote consumers health and well-being by consistent modification of their f

DOSIMETRY AND CANCER RISK ESTIMATIONS FOR DIFFERENT RADIATION PROTECTION SOLUTIONS AT DECOMMISSIONING A CONTAMINATED NUCLEAR POWER PLANT SITE

Contaminated sediments originating from dredging activities in a nuclear power plant site were placed in a pond, which has to be taken into consideration during the future decommissioning process. The sediments have to be handled to free release the site. The radionuclides Co-60 and Cs-137 were identified and the activity concentrations (Bq/kg) were quantified in the range of 10-6000 and 5-50 Bq k

Guiding the First-Year Student Entrepreneur : A Conceptual Map to Nudge Towards the Reversal Effect in Learning

This chapter addresses a recent argumentation in entrepreneurship education for the term odigogy, meaning to guide. The role of guidance has so far been discussed in relation to the balance between pedagogy and andragogy as well as between teacher- and student-led learning. The purpose of this chapter is to further develop odigogy, conceptualise a map for how to reason when facing first-year stude

Hippocampal output profoundly impacts the interpretation of tactile input patterns in SI cortical neurons

Due to continuous state variations in neocortical circuits, individual somatosensory cortex (SI) neurons in vivo display a variety of intracellular responses to the exact same spatiotemporal tactile input pattern. To manipulate the internal cortical state, we here used brief electrical stimulation of the output region of the hippocampus, which preceded the delivery of specific tactile afferent inp

Generation of human-induced pluripotent-stem-cell-derived cortical neurons for high-throughput imaging of neurite morphology and neuron maturation

High-throughput imaging allows in vitro assessment of neuron morphology for screening populations under developmental, homeostatic, and/or disease conditions. Here, we present a protocol to differentiate cryopreserved human cortical neuronal progenitors into mature cortical neurons for high-throughput imaging analysis. We describe the use of a notch signaling inhibitor to generate homogeneous neur

Balancing selection on the complement system of a wild rodent

Background: Selection pressure exerted by pathogens can influence patterns of genetic diversity in the host. In the immune system especially, numerous genes encode proteins involved in antagonistic interactions with pathogens, paving the way for coevolution that results in increased genetic diversity as a consequence of balancing selection. The complement system is a key component of innate immuni

Transanal formation of anastomosis using C-REX device is feasible and effective in high anterior resection

Purpose: C-REX is a novel instrument for creating stapleless colorectal anastomosis by compression. The aim of this study was to evaluate the feasibility and effectiveness of C-REX in open and laparoscopic high anterior resections. Methods: A prospective clinical safety study on 21 patients reconstructed with C-REX colorectal anastomosis following high anterior resection of the sigmoid colon using

The Swedish Childhood Tumor Biobank (BTB) is a nonprofit national infrastructure for collecting tissue samples and genomic data from pediatric patients diagnosed with central nervous system (CNS) and other solid tumors. The BTB is built on a multidisciplinary network established to provide the scientific community with standardized biospecimens and genomic data, thereby improving knowledge of the

Energy systems in sustainability-profiled districts in Sweden : A literature review and a socio-technical ecology approach for future research

Over the past 30 years, several sustainability-profiled districts have been developed in Sweden with high ambitions for the energy systems, such as Hammarby Sjöstad in Stockholm and Western Harbor in Malmö. Research into energy systems in urban districts is interdisciplinary and therefore spread over different areas, which means that an overview of the current state of knowledge and lessons learne

European practice patterns for antiplatelet management in NSTE-ACS patients : Results from the REal-world ADoption survey focus on Acute antiPlatelet Treatment (READAPT) survey

Background: The 2020 European Society of Cardiology (ESC) guidelines for the diagnosis and management of patients with non-ST elevation-acute coronary syndrome (NSTE-ACS) recommend early invasive coronary angiography in high-risk patients and no routine pre-treatment with oral P2Y12 receptor inhibitor in NSTE-ACS patients prior to defining coronary anatomy. Objective: To assess the implementation

Comparison of force fields to study the zinc-finger containing protein NPL4, a target for disulfiram in cancer therapy

Molecular dynamics (MD) simulations are a powerful approach to studying the structure and dynamics of proteins related to health and disease. Advances in the MD field allow modeling proteins with high accuracy. However, modeling metal ions and their interactions with proteins is still challenging. NPL4 is a zinc-binding protein and works as a cofactor for p97 to regulate protein homeostasis. NPL4

Antioxidant Nutrients and Risk of Latent Autoimmune Diabetes in Adults and Type 2 Diabetes : A Swedish Case-Control Study and Mendelian Randomization Analysis

Antioxidant vitamins C and E are inversely associated with type 1 diabetes (T1D). We investigated if antioxidants are also associated with latent autoimmune diabetes in adults (LADA), with low (LADAlow) and high (LADAhigh) autoantibody levels, type 2 diabetes (T2D), and estimates of beta cell function (HOMA-B) and insulin resistance (HOMA-IR). We used Swedish case-control data with incident cases
