Excessive daytime sleepiness (EDS) is a common complaint in the general population and is associated with cardiovascular disease and increased mortality. We aimed to investigate whether sleep duration is related to excessive daytime sleepiness in the general population, both in itself and in combination with other factors. We performed a cross-sectional analysis in the population-based Swedish CAr

Purpose: To investigate if hip and knee alignment assessed 2 years after anterior cruciate ligament (ACL) injury is associated with compartment-specific radiographic knee osteoarthritis (OA) 3 years later. Methods: An exploratory analysis was conducted in the knee ACL, nonsurgical versus surgical treatment (KANON) trial (ISRCTN84752559); 115 subjects with acute ACL injury were assessed at the 2-ye

Dune slacks are biodiverse seasonal wetlands within sand dune systems, strongly influenced by the dynamics of the local groundwater regime. Future climate predictions indicate strong adverse impact on the hydrology and therefore ecology of these wetland ecosystems. In this study we aimed to find the most appropriate hydrological and ecological indicators to summarise dune slack plant community res

Herein, a model is developed to study the polarization-selective light-coupling in quantum well infrared photodetector arrays with 15 and 30 μm pixel pitch. The polarization-selective light-coupling is achieved using 1D lamella gratings with varying grating orientation and studied through 2D and 3D finite-element method simulations. The extracted absorption quantum efficiency ηabs, derived from th

Background/Objectives: Acute mesenteric ischemia (AMI) is life-threatening and difficult to diagnose in time. Unlike many cardiovascular diseases, the association between lifestyle factors such as diet, alcohol consumption, and physical activity and AMI is unknown. Methods: This study is a prospective cohort study with 28,098 middle-aged participants with a mean follow-up time of 23.1 years. Basel

Even though the one-dimensional contact interaction requires no regularization, renormalization methods have been shown to improve the convergence of numerical calculations considerably. In this work, we compare and contrast these methods: "the running coupling constant"where the two-body ground-state energy is used as a renormalization condition, and two effective interaction approaches that incl

Transit spectroscopy usually relies on the integration of one or several transits to achieve the signal-to-noise ratio (S/N) necessary to resolve spectral features. Consequently, high-S/N observations of exoplanet atmospheres, where we can forgo integration, are essential for disentangling the complex chemistry and dynamics beyond global trends. In this study, we combined two partial 4-UT transits

One of the outstanding goals of the planetary science community is to measure the present-day atmospheric composition of planets and link this back to formation. As giant planets are formed by accreting gas, ices, and rocks, constraining the relative amounts of these components is critical to understand their formation and evolution. For most known planets, including the solar system giants, this

The ferroelectric domain structure of a freestanding BiFeO3 film was visualized by ptychographic dichroic imaging with linearly polarized x-rays at the O K-edge around 530 eV. The dichroic contrast is maximized at the energy of the hybridization of the O 2p state and the Fe 3d orbitals, which is split by the octahedral crystal field of the perovskite structure. The microscopy images thus obtained

Background/Aim: An inverse association exists between type 2 diabetes mellitus (T2DM) and both plasma vitamin D levels and sun exposure, but vitamin D supplementation does not reduce the incidence. We sought to assess whether there is a dose-dependency in the association between sun exposure and T2DM. Patients and Methods: The melanoma in Southern Sweden (MISS) cohort is comprised of one thousand

Bone strength is a major contributor to fracture risk. Areal bone mineral density (aBMD) obtained from dual-energy X-ray absorptiometry (DXA) is used as a surrogate for bone strength in fracture risk prediction. 3D finite element (FE) models predict bone strength better than aBMD but need 3D computed tomography and are not automated. We have earlier developed a method to automatically reconstruct

Offentliga försäkringar kan göra äktenskap mindre sannolik, men för vem? Med hjälp av American Community Survey finner vi att en ökad sannolikhet att vara berättigad till offentlig hälsoförsäkring på grund av lagförändringar minskar giftermålsfrekvensen, särskilt bland personer med högre utbildningsnivåer. Vi utvecklar en sökmodell av äktenskapsmarknaden som visar att de med ett högt förväntat ekoPublic insurance may disincentivize marriage, but for whom? Using the American Community Survey, we find that an increased likelihood of Medicaid eligibility owing to the Affordable Care Act reduces marriage rates, particularly among people with higher education levels. We develop a search model of the marriage market that shows that those with a high expected financial surplus from marriage respo

The overall aim of this scoping review was to map the existing literature on residual placental blood volume in cesarean sections as an indirect measure of placental transfusion. Multiple databases including Pubmed, Cochrane, Embase and Web of Science were searched for relevant studies published between 1972 and 2023. All studies on cesarean sections with term pregnancies and information on residu

Introduction: Intact cord resuscitation promotes zero separation and facilitates skin-to-skin contact, regardless of delivery mode. Therefore, this study aims to illuminate parents' experiences of intact cord resuscitation in the mother's bed. Method: Interviews with seven mothers, one father and seven couples were analysed using Lindseth and Norberg's phenomenological hermeneutics. Results: The a

BACKGROUND: Long-term oxygen therapy (LTOT) improves survival in patients with chronic severe resting hypoxaemia, but effects on hospitalisation are unknown. This study evaluated the potential impact of starting LTOT on acute exacerbation and hospital burden in patients with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) and pulmonary hypertension (PH).METHODS: Longi

Deoxynivalenol (DON) is a common mycotoxin in crops that could induce intestinal inflammation, affecting the susceptibility of intestinal epithelial cells (IECs) to pathogen infection. This study aimed to investigate DON's effects on mucin and cytokine production as part of the local immune system and how it affected intestinal susceptibility to pathogen infection. Caco-2 cells were exposed to DON

Ethanolamines are often added in the empirical formulation of commercial hard-surface cleaners and degreasers. Their use is usually justified by the fact they are anti-corrosive agents. However, their direct influence on cleaning performance is not well understood. In this work the cleaning performance of formulations with and without mono-ethanolamine (MEA) have been tested on standard polymerize

BACKGROUND: Several widely used drugs have photosensitizing properties, and much research has been conducted to find associations between their use and the risk of developing cutaneous malignant melanoma (cM), basal cell carcinoma (BCC) or cutaneous squamous cell carcinoma (cSCC), often with conflicting results.OBJECTIVE: To assess whether the use of commonly prescribed photosensitizing drugs incr

The increasing demand for renewable energy accounts for the DC microgrid concept, facilitating the integration of photovoltaic (PV) modules and battery energy systems (BESS) into a common DC bus. In light of this, bipolar DC-DC converters can result in two symmetric DC buses that provide more flexibility. This article presents a hybrid bipolar converter by merging a single-ended primary-inductor c
