Strategies and Combinations of Measures for Renovations of Swedish Heritage Buildings – A Review

In order to achieve environmental goals, the impact of the European building stock on the environment needs to be reduced through renovation measures. However, regarding heritage buildings, the choice of measure(s) must simultaneously consider the preservation of cultural and historical values. Besides the impact on such values, energy-efficiency measures can result in increased risks for moisture

Limited beneficial effects of systemic steroids when added to standard of care treatment of seasonal allergic rhinitis

Intramuscular injections with methylprednisolone treating allergic rhinitis (AR) have a long history. Modern guidelines are designed to dissuade this treatment, but it´s frequently used, especially in primary care. This despite of concern for side effects and lack of modern placebo-controlled studies. This study was designed to evaluate if methylprednisolone, could significantly improve symptoms o

Sensory evolution : A dazzling hack to cope with bright light in owls and whales

When exposed to sudden changes in light intensity, rod-dominated retinas of animals with highly sensitive dim-vision risk critical damage. A new study finds that owls and deep-diving whales have evolved an identical photoprotection mechanism to delay toxic all-trans retinal release, a discovery with potential medical implications.

Laser-induced, single droplet fragmentation dynamics revealed through megahertz x-ray microscopy

The fragmentation dynamics of single water droplets from laser irradiation is studied with megahertz frame rate x-ray microscopy. Owed to the nearly refraction-free and penetrating imaging technique, we could look into the interior of the droplet and reveal that two mechanisms are responsible for the initial explosive fragmentation of the droplet. First, reflection and diffraction of the laser bea

Prevalence and prognostic value of electrocardiographic abnormalities in hypokalemia: A multicenter cohort study

AbstractBackgroundHypokalemia is common in hospitalized patients and associated with ECG abnormalities. The prevalence and prognostic value of ECG abnormalities in hypokalemic patients are, however, not well established.MethodsThe study was a multicentered cohort study, including all ault patients with an ECG and potassium level 100 bpm predicted both mortality and ICU admission among patients wit

Prior electrocardiograms not useful for machine learning predictions of major adverse cardiac events in emergency department chest pain patients

At the emergency department (ED), it is important to quickly and accurately determine which patients are likely to have a major adverse cardiac event (MACE). Machine learning (ML) models can be used to aid physicians in detecting MACE, and improving the performance of such models is an active area of research. In this study, we sought to determine if ML models can be improved by including a prior

Comparison between ticagrelor and clopidogrel in myocardial infarction patients with high bleeding risk

Aims Ticagrelor is associated with a lower risk of ischemic events than clopidogrel. However, it is uncertain whether the benefits of more intensive anti-ischemic therapy outweigh the risks of major bleeding in patients who have a high bleeding risk (HBR). Therefore, this study compared ticagrelor and clopidogrel in myocardial infarction (MI) patients with HBR. Methods and results This study inclu

A Wide Metallicity Range for Gyr-old Stars in the Nuclear Star Cluster

We report metallicities for three ∼Gyr-old stars in the Milky Way nuclear star cluster (NSC) using high-resolution near-infrared spectroscopy. We derive effective temperatures from a calibration with Sc line strength, which yields results in good agreement with other methods, and metallicities from spectral fits to Fe i lines. Our derived metallicities range from −1.2 < [Fe/H] < + 0.5, a span of 1

Decongestants and antihistamines for acute otitis media in children

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the benefits and harms of decongestants and antihistamines in the treatment of AOM in children. Specifically, we want to assess the impact of decongestants and antihistamines on the presence of otalgia, the persistence of AOM, the need for or change in antibiotic therapy, severe complicat

Observations of very fast electron traps at SiC/high-κ dielectric interfaces

Very fast interface traps have recently been suggested to be the main cause behind poor channel-carrier mobility in SiC metal-oxide-semiconductor field effect transistors. It has been hypothesized that the NI traps are defects located inside the SiO2 dielectric with energy levels close to the SiC conduction band edge and the observed conductance spectroscopy signal is a result of electron tunnelin

Anti-Incretin Gut Features Induced by Feed Supplementation with Alpha-Amylase : Studies on EPI Pigs

The acini-islet-acinar (AIA) axis concept justifies the anatomical placement of the Langerhans islets within the exocrine pancreatic parenchyma and explains the existence of the pancreas as a single organ. Amylase has been suggested to play a key role as an anti-incretin factor. Oral glucose tolerance tests (OGTT) were performed on 18 piglets in both a healthy (prior to pancreatic duct ligation (P

A new way of reducing negative weights in MC@NLO

We introduce a new technique, that we dub Born spreading, aimed at reducing the number of negative-weight S events in the MC@NLO matching of NLO calculations with parton-shower simulations. We show that such a technique, based on a re-distribution of Born matrix elements in the radiative phase space, achieves a sizeable reduction of negative-weight events at little computational cost. The method d

Multiconfigurational Pair-Density Functional Theory Is More Complex than You May Think

Multiconfigurational pair-density functional theory (MC-PDFT) is a promising way to describe both strong and dynamic correlations in an inexpensive way. The functionals in MC-PDFT are often “translated” from standard spin density functionals. However, these translated functionals can in principle lead to “translated spin densities” with a nonzero imaginary component. Current developments so far ne

Anionic nanoplastic contaminants promote Parkinson’s disease–associated α-synuclein aggregation

Recent studies have identified increasing levels of nanoplastic pollution in the environment. Here, we find that anionic nanoplastic contaminants potently precipitate the formation and propagation of α-synuclein protein fibrils through a high-affinity interaction with the amphipathic and non-amyloid component (NAC) domains in α-synuclein. Nanoplastics can internalize in neurons through clathrin-de

The association of copeptin with metabolic risk markers is modified by region of origin

Iraqi born immigrants in Sweden have higher prevalence of metabolic diseases compared to native Swedes. Copeptin, a marker for vasopressin, is associated with increased risk of metabolic disease. In this cross-sectional population study based on the MEDIM cohort we investigated differences in copeptin levels between Iraqi and Swedish born individuals and if the association between copeptin and car

Room temperature two-dimensional electron gas scattering time, effective mass, and mobility parameters in AlxGa1−xN/GaN heterostructures (0.07 ≤ x ≤ 0.42)

Al x Ga 1 − x N/GaN high-electron-mobility transistor (HEMT) structures are key components in electronic devices operating at gigahertz or higher frequencies. In order to optimize such HEMT structures, understanding their electronic response at high frequencies and room temperature is required. Here, we present a study of the room temperature free charge carrier properties of the two-dimensional e

Impact of Added Thermal Insulation on Cold Attics in Apartment Buildings in Temperate Climate – A Review

Added insulation in cold attics can be an efficient and profitable energy efficiency measure. Simultaneously, added insulation increases the risk of a decreased temperature in the attic, thereby increasing the risk of high relative humidity and moisture damage. This paper collocates and reviews previous publications that deal with the impact of added insulation on attics as a renovation measure. T

Adopting Real Measurements to a Simulation Model for Indoor Temperature Increase at Reduced Cooling Power to Lower Power Peaks

Lately there has been an increasing focus on saving peak power in heating systems as a way to lower the environmental load past just saving energy. At the same time, active cooling is becoming increasingly interesting. Sweden has more and more cooling systems with an increase in cooling also in residential buildings. The cooling power is much more expensive than the heating power. Therefore, there

Socioeconomic disparities in attention deficit hyperactivity disorder (ADHD) in Sweden : An intersectional ecological niches analysis of individual heterogeneity and discriminatory accuracy (IEN-AIHDA)

We aimed (i) to gain a better understanding of the demographic and socioeconomical distribution of ADHD risk in Sweden; and (ii) to contribute to the critical discussion on medicalization, i.e., the tendency to define and treat behavioural and social problems as medical entities. For this purpose, we analysed the risk of suffering from ADHD in the whole Swedish population aged between 5 and 60 yea
