Identification of patients at risk to develop atrial fibrillation (AF) can enable more frequent follow-up and lead to earlier detection of AF. The aim of this project was to perform long-term AF prediction based on a novel set of ECG-derived features describing the characteristics of supraventricular arrhythmias present before new onset AF. In total, 12 199 patients aged 75/76 performed repeated s
The JPL rover Perseverance's investigations of Jezero crater's floor reveal that the ultramafic Séítah formation and the overlying mafic Máaz formation are deformed into a broad, low-amplitude structural dome. Mastcam-Z stereo images processed into digital outcrop models, together with RIMFAX ground-penetrating radar profiles, were used to reconstruct the three-dimensional stratal geometry of both
Chronic suppurative otitis media (CSOM) is a long-term inflammatory disease of the middle ear that can cause persistent ear discharge and hearing loss. EarClean is an ear pipette intended to enable simple and cost-effective rinsing and cleaning of the ear canal. For safe clinical use, it is importantto evaluate whether the pressure generated during use may pose a risk of damaging the tympanic memb
Mental health challenges among Chinese emerging adults have become an increasingly important public concern, yet the interplay between family relational environments and dispositional vulnerability remains insufficiently examined. Drawing on attachment theory, this study examines the direct and indirect relationships between perceived parent–child attachment quality, trait neuroticism, and depress
Våtmarker bidrar med många ekosystemtjänster såsom kolinlagring och förbättrad vattenkvalitet och tillgänglighet. Historisk dränering har dock lett till en massiv förlust av våtmarker världen över, vilket resulterat i förlorade ekosystemfunktioner och ökade utsläpp av växthusgaser. Idag finns ett ökat intresse för återställning av våtmarker för att nå beslutade klimat- och miljömål. Det finns dockPeatlands provide several ecosystem services such as carbon sequestration and improved water quality and availability. However, historical drainage has led to a massive loss of peatlands worldwide, resulting in lost ecosystem functions and increased greenhouse gas emissions. Today, environmental goals have led to a renewed interest in the restoration of peatlands. However, knowledge gaps regarding
Monitoring suspended sediment concentration (SSC) is essential for water-quality management and for anticipating sediment-related impacts. Yet sparse in situ measurements limit tracking SSC at high temporal and spatial resolution. We address this gap with a scalable approach that couples multispectral imagery (Landsat-8/9, Sentinel-2), remote sensing precipitation product (CHIRPS), and soil proper

Objective. Ileal pouch anal anastomosis ( IPAA) is the preferred method for restorative surgery in patients with ulcerative colitis who have to undergo proctocolectomy. The most common complication is pouchitis and several studies have pointed to the microbiota of the pouch as being a risk factor. The aim of this study was to follow the development of the bacterial microbiota in pouches during the
The four-year visual outcome was retrospectively studied in patients with older-onset diabetes mellitus and diabetic retinopathy in need of laser treatment. Visual acuity in 53 patients examined by ophthalmologists who referred the patients for an evaluation of retinopathy before laser treatment, was compared to that of 47 patients examined by ophthalmologists who also performed the photocoagulati
A common methodology for analyzing metalworking fluid (MWF) aerosols in workplace air is based on gravimetry before and after organic solvent extraction of the MWFs from a suitable collection filter: Because MWFs have different chemical and physical properties, various mixtures of organic solvents have been used to extract the MWFs from their collection device. An alternative to organic solvents,
Poly(styrene-graft-ethylene oxide), having alkyl chains (C-12 or C-18) on the polystyrene main chain or on the poly(ethylene oxide) (PEO) side chains, were synthesized. The main chain was alkylated by first ionizing amide groups in a styrene/acrylamide copolymer with tert-butoxide, and then using the amide anions as sites for reactions with 1-bromoalkanes. An excess of amide anions was used in the
This work presents a review of studies on the process economics of ethanol production from lignocellulosic materials published since 1996. Our objective was to identify the most costly process steps and the impact of various parameters on the fi- nal production cost, e.g. plant capacity, raw material cost, and overall product yield, as well as process configuration. The variation in estimated etha
This study was conducted to explore treatment and disease-related effects on health-related quality of life (HRQoL) in patients with aggressive lymphoma, to identify predictors for impaired long-term HRQoL, and to analyze the prognostic value of pretreatment HRQoL. Ninety-five patients with aggressive lymphoma, constituting a subset of a randomized multicenter trial comparing CHOP and MACOP-B, ent
Inhibition of oxidative metabolism is often found to decrease contractility of systemic vascular smooth muscle, but not to reduce global [Ca(2+)](i). In the present study, we probe the hypothesis that it is associated with an altered pattern of intracellular Ca(2+) oscillations (waves) influencing force development. In the rat tail artery, mitochondrial inhibitors (rotenone, antimycin A, and cyani
Objective:To determine whether the combined intervention of 50 000 IU vitamin A administered together with Bacille Calmette-Guerin (BCG) vaccination at birth was associated with adverse events, in particular bulging fontanels and adverse reactions to BCG.Subjects/Methods:From an ongoing trial, 2145 infants randomized to 50 000 IU vitamin A or placebo with BCG vaccination were recruited. Adverse ev
Background. Echocardiographically determined left atrioventricular plane displacement (AVPD) is strongly related to prognosis in patients with chronic heart failure and in postmyocardial infarction patients. We aimed at exploring whether AVPD, unlike ejection fraction, is related to mortality in patients with stable coronary artery disease (CAD). Methods and results. Atrioventricular plane displac
Apolipoprotein M (apoM) is a novel apolipoprotein presented mostly in high-density lipoprotein (HDL) in human plasma. Previously we have reported that both leptin and leptin receptor are essential for apoM expression in vivo. The expression of apoM is lower in the leptin deficient (ob/ob) mouse and leptin receptor deficient (db/db) mouse than in the normal mouse. In the present study, however, we
BACKGROUND: The interpretation of clinical trials and efforts directed at reducing the worldwide burden of coronary disease must take regional differences into account. This study examined the regional differences in baseline characteristics, treatment, and outcome in patients presenting with ST elevation myocardial infarction (STEMI) who were entered into the Magnesium in Coronaries (MAGIC) trial
Objectives. To study trends in treatment, health status and health-related quality of life (HRQL) in two cross-sectional surveys over a 5-yr period and in an observational follow-up sub-cohort based on a population-based rheumatoid arthritis (RA) register in Malm6, Sweden. Material and methods. A continuously updated population-based RA register was established in Malm6 city in southern Sweden in
The aim of this work was to study the leaching of hazardous substances in additives and admixtures that are commonly contained in concrete. Time-dependent leaching has been analyzed for three types of metal containing concretes: with ordinary Portland cement (OPC), fly ash, and slag. The concretes had uniform leaching patterns, clearly above detection limits. The prolonged diffusion test of 1,700
