Background and purpose — Patient-reported outcome (PRO) in total knee arthroplasty (TKA) patients with high body mass index (BMI) is controversial. We compared pain, function, quality of life, general health, and satisfaction among different BMI categories preoperatively and 1 year after primary TKA. Patients and methods — 4,318 patients were operated with a TKA for knee osteoarthritis in the Regi

For older people using long-term care services, the conditions of their life-space may be critical. The relationships between the physical housing environment and aspects of health were examined among older people in Japan (aged 65+ years, N = 1,928) by multivariable logistic regression analysis, adjusting for sociodemographic characteristics. Lack of safety, low access to emergency assistance, lo

In this paper we consider trajectory recovery for two cameras directed towards the floor, and which are mounted rigidly on a mobile platform. Previous work for this specific problem geometry has focused on locally minimising an algebraic error between inter-image homographies to estimate the relative pose. In order to accurately track the platform globally it is necessary to refine the estimation

This paper studies the long-term behaviour of a continuous time Markov chain formed by two non-negative integer valued components that evolve subject to a competitive interaction. In the absence of interaction the Markov chain is just a pair of independent linear birth processes with immigration. Interactions of interest include, as a special case, the famous Lotka-Volterra interaction. The Markov

What do we need to know about our students to better provide for more equitable outcomes? Who will succeed depends on many factors, and student personality traits constitute one factor that has received less attention in the engagement and teaching literature. The aim of the present study is to add to discussions on teaching in higher education by exploring how students differ on personality trait

It is a well‐known fact in scanning probe microscopy that the tip geometry will be convoluted with the shape of the sample. In this study we report on a clear‐cut in situ direct observation of the real shape of the atomic force microscopy (AFM) tip using the AFM technique itself, utilizing a specially designed sample. The sample was an array of columns fabricated using aerosol deposition of metal

The impact of many unfavorable childhood traits or diseases, such as low birth weight and mental disorders, is not limited to childhood and adolescence, as they are also associated with poor outcomes in adulthood, such as cardiovascular disease. Insight into the genetic etiology of childhood and adolescent traits and disorders may therefore provide new perspectives, not only on how to improve well

OBJECTIVE: Gestational diabetes mellitus (GDM) is a transient form of diabetes characterized by impaired insulin secretion and action during pregnancy. Population-based differences in prevalence exist which could be explained by phenotypic and genetic differences. The aim of this study was to examine these differences in pregnant women from Punjab, India and Scandinavia.METHODS: 85 GDM/T2D loci in

In extending the analysis of the four secular resonances between close orbits in Li and Christou (Celest Mech Dyn Astron 125:133–160, 2016) (Paper I), we generalise the semianalytical model so that it applies to both prograde and retrograde orbits with a one-to-one map between the resonances in the two regimes. We propose the general form of the critical angle to be a linear combination of apsidal

Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry and photometry are unprecedented. Aims. We highlight the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD). Gaia allows us to present many different HRDs,

A search for four-top-quark production, tttt, is presented. It is based on proton-proton collision data with a center-of-mass energy s=13 TeV collected by the ATLAS detector at the Large Hadron Collider during the years 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb-1. Data are analyzed in both the single-lepton and opposite-sign dilepton channels, characterized by the presenc

Background: Earlier research has investigated psychosocial and educational issues in populations of patients with cleft identifying several areas of concern. The objective of this study was to investigate current beliefs and knowledge about psychosocial and educational issues in parents and health care professionals (HCP) of children with cleft lip and/or palate (CL/P). Method: Parents were interv

Objective: To determine whether high DNA stainability (HDS), as assessed by the sperm chromatin structure assay (SCSA), predicts the risk of early miscarriage after in vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI). Design: Retrospective cohort study of consecutive pregnancies after IVF and ICSI treatment. Setting: Reproductive medicine center. Patient(s): A total of 1,602 pr
