Purpose: To characterize pre- and perioperative factors associated with treatment for wet age-related macular degeneration (wet AMD) after cataract surgery. Methods: This register-based cohort study with data from the Swedish National Cataract Register (NCR) and the Swedish Macula Register (SMR) from 2010 to 2017 compared eyes with and without preoperative AMD that had undergone cataract surgery a

The evaluation of simulated disasters (for example, exercises) and real responses are important activities. However, little attention has been paid to how reports documenting such events should be written. A key issue is how to make them as useful as possible to professionals working in disaster risk management. Here, we focus on three aspects of a written evaluation: how the object of the evaluat

Smart vehicles are emerging as a possible solution for multiple concerns in road traffic, such as mobility and safety. This work presents radio localization methods based on simultaneous direction of arrival (DOA), time-delay, and range estimation using the SAGE algorithm. The proposed methods do not rely on external sources of information, such as global navigation satellite systems (GNSS). The p

Background: The lack of access to essential surgical care in low-income countries is aggravated by emigration of locally-trained surgical specialists to more affluent regions. Yet, the global diaspora of surgeons, obstetricians, and anesthesiologists from low-income and middle-income countries has never been fully described and compared with those who have remained in their country of origin. It i

Objective: This study aims to test a Chinese cross-cultural adaptation of the English version of the Person-Centred Care Assessment Tool (P-CAT)and evaluate its psychometric properties. Design: P-CAT was translated/back-translated using established procedures before the psychometric evaluation of the Chinese version was made. Setting: Two hospitals covering urban and suburban areas of Kunming in tOBJECTIVE: This study aims to test a Chinese cross-cultural adaptation of the English version of the Person-Centred Care Assessment Tool (P-CAT) and evaluate its psychometric properties.DESIGN: P-CAT was translated/back-translated using established procedures before the psychometric evaluation of the Chinese version was made.SETTING: Two hospitals covering urban and suburban areas of Kunming in th

Introduction: Chronic breathlessness is associated with poorer quality of life (QoL). This population study aimed to define dimensions of QoL and duration and dominant causes of breathlessness that most diminished QoL. Methods: This cross-sectional, population-based, and randomized survey of adults (n = 2977) in South Australia collected data on demographics, modified Medical Research Council (mMR

The search for mates and food is mediated by volatile chemicals. Insects sense food odorants and sex pheromones through odorant receptors (ORs) and pheromone receptors (PRs), which are expressed in olfactory sensory neurons. Molecular phylogenetics of ORs, informed by behavioral and functional data, generates sound hypotheses for the identification of semiochemicals driving olfactory behavior. Stu

Background: ECG changes after revascularization predicts improved outcome for patients with ST-elevation myocardial infarction (STEMI). Worst lead residual (WLR) ST deviation and resolution of worst lead ST elevation (rST elevation) are simple measures that can be obtained early after PCI. The objective of the current study was to investigate whether simple ECG measures, obtained one hour followin

Background: Both single factors and composite measures have been suggested to predict mortality in patients with chronic obstructive pulmonary disease (COPD) and there is a need to analyze the relative importance of each variable. Objective: To explore the predictors of mortality for patients with COPD in relation to respiratory, cardiac, and malignant causes, as well as all causes of death. Metho

Background: Melanoma is a type of superficial tumor. As advanced melanoma has a poor prognosis, early detection and therapy are essential to reduce melanoma-related deaths. To that end, there is a need to develop a quantitative method for diagnosing melanoma. This paper reports the development of such a diagnostic system using hyperspectral data (HSD) and a convolutional neural network, which is a

Background: Reduction of insertion injury is likely important to approach physiological conditions in the vicinity of implanted devices intended to interface with the surrounding brain. New methods: We have developed a novel, low-friction coating around frozen, gelatin embedded needles. By introducing a layer of thawing ice onto the gelatin, decreasing surface friction, we mitigate damage caused b

Wheat bran arabinoxylan can be converted by enzymatic hydrolysis into short arabinoxylo-oligosaccharides (AXOS) with prebiotic potential. Alkali extraction of arabinoxylan from wheat-bran offers advantages in terms of yield and results in arabinoxylan with highly-substituted regions which has been a challenge to hydrolyse using endoxylanases. We show that this hurdle can be overcome by selecting a

We determine a counterexample to strong diamagnetism for the Laplace operator in the unit disc with a uniform magnetic field and Robin boundary condition. The example follows from the accurate asymptotics of the lowest eigenvalue when the Robin parameter tends to − ∞.

Objective: The aim was to analyse risk of forearm fractures in first- and second-generation immigrants to Sweden. Methods: A nationwide study of individuals 20 years of age and older was conducted. Forearm fractures were defined as at least one registered diagnosis in the National Patient Register between January 1, 1998 and December 31, 2012. Cox regression analysis was used to estimate the relat

Instead of featuring a long-awaited convergence process, the second half of the twentieth century witnessed a dramatic income divergence across countries. We propose cultural distance between countries as a determinant of this economic divergence. Cultural similarity makes it easier for societies to interact, learn and adopt from one another. Consequently, cultural differences may lead to economic

This brief note, on the Bundesverfassungsgericht’s Weiss judgment of 5th May 2020, highlights three implications of the German Federal Constitutional Court’s landmark ruling and its constitutional significance with implications for the wider context of Member States’ cooperation in the EU and European integration as a whole. We explain the relevant background of the judgment and argue that the spe

1. Dementia is a clinical syndrome with several causes whichcreates impairments in mental ability, personality, affect andsocialisation.2. Information from family members can be very useful in theearly identification of cognitive impairment.3. Patients presenting with cognitive impairment should be evaluatedfor potentially reversible causes, with a range of laboratorytests and investigations.4. Sh

Apart from microhardness and elastic modulus, the stress-strain relation is another important characteristic that more and more scholars have been trying to extract from nanoindentation. With the development of artificial intelligence and computer technology, a machine learning based method is proposed in this paper to extract stress-strain curve of grey cast iron using sharp nanoindentation. Firs

Building extraction has attracted considerable attention in the field of remote sensing image analysis. Fully convolutional network modelling is a recently developed technique that is capable of significantly enhancing building extraction accuracy. It is a prominent branch of deep learning and uses advanced state-of-the-art techniques, especially with regard to building segmentation. In this paper

Abstrakt. Gradientval av överföringar gör det möjligt att förenkla polarisationsöverföringssekvenser genom att utelämna kemiska skift-återfokuseringspulser. Funktionerna hos en förenklad STEM-sekvens med tre pulser för {1H-13C} polarisationsöverföring har studerats vid 2 Tesla på ett helkropps MR-system med avseende på användning av MR-spektroskopi in vivo. Den observerade signalen ökas genom nett
