Summary: We studied the risk for hip fracture before and after total knee replacement (TKR) in the entire population in Sweden. Women and men had a low risk for hip fracture before TKR but an increased risk the first year after TKR. Purpose: It is known that osteoarthritis is associated with high bone mass. We therefore studied the risk of hip fracture before and after total knee replacement (TKR)

In the present work we have performed classical molecular dynamics modelling to investigate the effects of different types of force-fields on the stress-strain and yielding behaviours in semi-crystalline lamellar stacked linear polyethylene. To this end, specifically the all-atomic optimized potential for liquid simulations (OPLS-AA) and the coarse-grained united-atom (UA) force-fields are used to

BackgroundRotator cuff tears pose a huge socioeconomic burden. Our study uses Fourier transform infrared spectroscopy (FTIR) as it is a quick, non-manipulative and non-destructive test, which can identify a wide range of chemical targets from small intraoperatively obtained specimens. The aim of this study was (i) to characterise the chemical and structural composition of rotator cuff tendons and

In the set of commentaries on liquidity entitled “The continuing significance of social structure in liquid modernity,” three sets of authors set out to examine the relationship between liquidity and structure, value, and distinction. In doing so, they attempt to marry theories which argue against sociologist Zygmunt Bauman’s central thesis that societal structures are shifting with his seminal co

This article explores relevant laws and doctrines of patent infringement in Europe with a special emphasis on 3D printing (3DP) technologies. Considering the difficulties that patent owners might face in pursuing direct patent infringement actions in the rapidly evolving era of 3DP, we suggest that patent owners will most likely direct their efforts towards indirect patent infringement strategies.

Introduction: The aim of the study is to compare the effect of cervical length measured with transvaginal ultrasound in the second trimester on the risk of spontaneous preterm delivery (PTD) between different risk groups of asymptomatic women with a singleton pregnancy. Material and methods: This is a pre-planned exploratory analysis of the CERVIX study, a prospective blinded multicenter diagnosti

Local governments are increasingly relying on municipally owned corporations (MOCs) to provide public services. Some describe this development as a rational response to austerity challenges and emphasise the cost-efficiency of MOCs (‘the optimistic view’). Others identify complications and associate MOCs with weak supervision, lack of accountability, and corruption risks (‘the sceptical view’). Hi

Expansive cements are utilised in special applications to improve properties such as cracking caused by drying shrinkage. Several types of expansive cements exist and the main hydration product responsible for the expansion is ettringite, [Ca₃Al(OH)₆]₂(SO₄)₃·26H ₂O. The importance of the cement phase containing alumina is well known

Popular Abstract in Swedish När födan efter en måltid kommer ned i tunntarmen, utsöndras ett protein som heter cholecystokinin, förkortat CCK, ifrån tarmslemhinnan till blodet. Ett ämne som frisätts på detta sätt till blodcirkulationen för att påverka celler i andra organ i kroppen kallas för hormon. CCK påverkar gallblåsan till att dra ihop sig och tömma sitt innehåll samtidigt som bukspottkörtelCholecystokinin (CCK) is known to exert secretory and trophic effects on the pancreas. Its release from the intestinal mucosa is regulated by pancresic proteases in the small intestine. However, knowledge about the type of responding exocrine cells and the time course of events during stimulation with CCK is lacking. Further, the role of CCK in the regulation of growth in other digestive organs is

Combining the strengths of an advanced mathematical model of human physiology and a thermal manikin is a new paradigm for simulating thermal behaviour of humans. However, the forerunners of such adaptive manikins showed some substantial limitations. This project aimed to determine the opportunities and constraints of the existing thermal manikins when dynamically controlled by a mathematical model

By being predicated on supervised machine learning, pattern recognition approaches to myoelectric prosthesis control require electromyography (EMG) training data collected concurrently with every detectable motion. Within this framework, calibration protocols for simultaneous control of multifunctional prosthetic hands rapidly become prohibitively long - the number of unique motions grows geometri

The coronavirus pandemic triggered strong political action across Europe. Mandatory restrictions to increase social distancing were imposed, commonly known as lockdowns. In some cases, entire countries were virtually locked down for several weeks at a time, contributing to a very severe downturn in economic activity. To mitigate the policy induced economic crisis, governments responded by introduc

Large networks of weather radars are comprehensive instruments for studying bird migration. For example, the US WSR-88D network covers the entire continental US and has archived data since the 1990s. The data can quantify both broad and fine-scale bird movements to address a range of migration ecology questions. However, the problem of automatically discriminating precipitation from biology has si

Thin films of the lead-free ferroelectric Na0.5Bi0.5TiO3 grown on thin-film Pt electrodes supported by SrTiO3 substrates have a complex microstructure consisting of crystalline grains with three distinct major crystallographic orientations. The piezoelectric response measured in spatially separated sub-micron grains using time-resolved synchrotron x-ray microdiffraction is highly inhomogeneous eve

Deficiencies of C2 and other components of the classical pathway of complement are associated with increased risk of infections with encapsulated bacteria, such as Haemophilus (H.) influenzae. Defense against H. influenzae is dependent on specific antibodies and complement, which mediate serum bactericidal activity (SBA) and opsonization. Due to lack of normal classical and lectin complement pathw

OBJECTIVE: This study used meta-analysis to assess disparities in cardiovascular disease (CVD) screening and treatment in people with mental disorders, a group that has elevated CVD incidence and mortality. METHODS: The authors searched PubMed and PsycInfo through July 31, 2020, and conducted a random-effect meta-analysis of observational studies comparing CVD screening and treatment in people wit

Environmental models are important tools; however uncertainty is pervasive in the modeling process. Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. One critical question has become: how focused should uncertainty intervals be with consideration of characteristics of uncertain input dat

Objective: The European Acquired Haemophilia registry (EACH2) collected data on the demographics, diagnosis, underlying disorders, bleeding characteristics, treatment, and outcome of women with acquired haemophilia A (AHA), a rare and often severe bleeding disorder caused by autoantibodies directed against coagulation factor VIII. Design: Prospective, multi-centre, large-scale, pan-European regi

The influence of demographic characteristics on the perceived needs of parents in a sample of staff and parents of admitted children in a paediatric hospital in Sweden were examined as part of a project in Sweden, England, Indonesia and Australia. Over 100 parents and 100 staff responded and responses compared, including perceived importance of each of the 51 needs. Few needs were influenced by de
