COVID-19 clinical outcomes and DMT of MS patients and population-based controls

Objective: To estimate risks for all-cause mortality and for severe COVID-19 in multiple sclerosis patients and across relapsing–remitting multiple sclerosis patients exposed to disease-modifying therapies. Methods: We conducted a Swedish nationwide population-based multi-register linkage cohort study and followed all multiple sclerosis patients (n = 17,692 in March 2020), individually age-, sex-,

The role of super-spreaders in modeling of SARS-CoV-2

In stochastic modeling of infectious diseases, it has been established that variations in infectivity affect the probability of a major outbreak, but not the shape of the curves during a major outbreak, which is predicted by deterministic models (Diekmann et al., 2012). However, such conclusions are derived under idealized assumptions such as the population size tending to infinity, and the indivi

Rates of instrumental vaginal birth and cesarean and quality of maternal and newborn health care in private versus public facilities : Results of the IMAgiNE EURO study in 16 countries

OBJECTIVE: To explore the quality of maternal and newborn care (QMNC) during the COVID-19 pandemic by facility type among 16 European countries, comparing rates of instrumental vaginal birth and cesarean.METHODS: Women who gave birth in the WHO European Region from March 1, 2020, to February 7, 2022, answered a validated online questionnaire. Rates of instrumental birth, instrumental vaginal birth

Systematic quark/gluon identification with ratios of likelihoods

Discriminating between quark- and gluon-initiated jets has long been a central focus of jet substructure, leading to the introduction of numerous observables and calculations to high perturbative accuracy. At the same time, there have been many attempts to fully exploit the jet radiation pattern using tools from statistics and machine learning. We propose a new approach that combines a deep analyt

A randomized controlled trial of the effectiveness of teacher continued professional development on student language outcomes

BACKGROUND: Continued professional development (CPD) is required for updated skills and knowledge. This study evaluates the efficacy of a CPD programme for mainstream school teachers.AIMS: In an 11-week intervention programme, speech-language therapists (SLTs) presented the participating teachers with whole-class teaching techniques aimed at creating a language and communication-supporting classro

Antibody-free measurement of cerebrospinal fluid tau phosphorylation across the Alzheimer's disease continuum

BACKGROUND: Alzheimer's disease is characterized by an abnormal increase of phosphorylated tau (pTau) species in the CSF. It has been suggested that emergence of different pTau forms may parallel disease progression. Therefore, targeting multiple specific pTau forms may allow for a deeper understanding of disease evolution and underlying pathophysiology. Current immunoassays measure pTau epitopes

Physiotherapy use is increased for up to nine months after receiving respiratory support for COVID-19

Aim: To explore whether physiotherapy use is increased after hospitalization with COVID-19 with or without respiratory support vs. other respiratory tract infections (RTI). Methods: In all Norwegian residents aged 18–80 years who were hospitalized with COVID-19 (N = 5,344) or other RTI (N = 82,235) between July 1st 2017 and August 1st 2021, we used a pre-post study design to explore the weekly ind

Mineral Soils Are an Important Intermediate Storage Pool of Black Carbon in Fennoscandian Boreal Forests

Approximately 40% of earth's carbon (C) stored in land vegetation and soil is within the boreal region. This large C pool is subjected to substantial removals and transformations during periodic wildfire. Fire-altered C, commonly known as pyrogenic carbon (PyC), plays a significant role in forest ecosystem functioning and composes a considerable fraction of C transport to limnic and oceanic sedime

Creating and detecting poor man's Majorana bound states in interacting quantum dots

We propose and theoretically investigate an alternative way to create the poor man's Majorana bound states (MBSs) introduced in Phys. Rev. B 86, 134528 (2012)10.1103/PhysRevB.86.134528. Our proposal is based on two quantum dots (QDs) with strong electron-electron interactions that couple via a central QD with proximity-induced superconductivity. In the presence of spin-orbit coupling and a magneti

Stellar feedback in M 83 as observed with MUSE : II. Analysis of the H II region population: Ionisation budget and pre-SN feedback

Context. Energy and momentum injected by young, massive stars into the surrounding gas play an important role in regulating further star formation and in determining the galaxy's global properties. Before supernovae begin to explode, stellar feedback consists of two main processes: Radiation pressure and photoionisation. Aims. We study pre-supernova feedback and constrain the leakage of Lyman cont

Decoding geochemical signals of the Schwalbenberg Loess-Palaeosol-Sequences — A key to Upper Pleistocene ecosystem responses to climate changes in western Central Europe

Loess deposits are the most extent continental archives of climatic- and environmental change and represent important components of local and global dust systems. Consequently, their geochemistry provides an excellent basis for studying climate oscillations on land and how these affect processes in the terrestrial system. It is, however, challenging to assess information archived in loess records

Physically-motivated basis functions for temperature maps of exoplanets

Thermal phase curves of exoplanet atmospheres have revealed temperature maps as a function of planetary longitude, often by sinusoidal decomposition of the phase curve. We construct a framework for describing two-dimensional temperature maps of exoplanets with mathematical basis functions derived for a fluid layer on a rotating, heated sphere with drag/friction, which are generalisations of spheri

Models and biomarkers of motor and neuropsychiatric complications in Parkinson’s disease

Parkinsons sjukdom är en kronisk neurodegenerativ sjukdom karaktäriserad avtypiska motoriska symtom i form av långsamma rörelser, muskelstelhet ochvilotremor. Dessa symtom orsakas av en brist på signalsubstansen dopamin i deområden av hjärnan som kontrollerar rörelser (hjärnbarken, basala ganglierna ochthalamus).

Parkinsonian motor symptoms are improved by dopaminergicmedications, the most effective being the dopamine precursor L-DOPA. Thiscompound exerts its motor effects by stimulating dopamine D1 and D2 receptors,whose expressio
