Preserved periprosthetic bone stock at 5 years post-operatively with uncemented short hip stem in both collared and collarless version
Introduction: Previous bone density studies have generally shown bone resorption around both cemented and uncemented total hip arthroplasty (THA) stems. This is presumed to be due to stress shielding. Short stems have been introduced partly to preserve bone in the proximal femur by a more physiological loading of the bone. The purpose of this study was to evaluate bone remodeling around a short, f
Downturn in Childhood Bone Mass : A Cross-Sectional Study Over Four Decades
Screen time and physical inactivity have increased among children. As physical activity is a determinant of bone mass, there is a concern that children today have lower bone mass than earlier. If this is true, fractures may become more common in the future. In 2017–2018, we used single-photon absorptiometry (SPA) to measure distal forearm bone mineral density (BMD; mg/cm2) in a normative cohort of

Physical Activity at Growth Induce Bone Mass Benefits Into Adulthood : A 15-Year Prospective Controlled Study
Daily school physical activity (PA) improves musculoskeletal traits. Whether or not benefits remain in adulthood is debated. We included in this study 131 children that took part in an intervention with 40 minutes of PA per school day (200 minutes per week) from age 6 to 9 years (grade one) to age 14 to 16 years (grade nine), whereas 78 children continued with national recommended school physical
Azide-Functionalized Naphthoxyloside as a Tool for Glycosaminoglycan Investigations
We present a xylosylated naphthoxyloside carrying a terminal azide functionality that can be used for conjugation using click chemistry. We show that this naphthoxyloside serves as a substrate for β4GalT7 and induces the formation of soluble glycosaminoglycan (GAG) chains with physiologically relevant lengths and sulfation patterns. Finally, we demonstrate its usefulness by conjugation to the Alex
Incidence and Predictors of Heart Failure in Patients With Atrial Fibrillation
Background: Heart failure (HF) is a frequent cause of hospitalization and death in patients with atrial fibrillation (AF). Identifying AF patients at risk of HF hospitalization could help select individuals for intensive follow-up and treatment. Methods: We pooled data from 3 randomized trials (ACTIVE-A, RE-LY, AVERROES) of AF patients, for derivation and internal validation of a risk score for fi
Proteome-wide analysis of severe bacterial infections. The battle between host and pathogen.
The pathogenesis of severe infectious diseases is a complex interplay between the host and the pathogen. The development and progression of a disease encompasses a multitude of processes, which balance between host-damage and host-protection. Proteomic analysis provides the necessary tools to interpret the extensive protein networks of host-pathogen interactions underlying the pathogenesis of a pa
Effect of an impinging jet on the flow characteristics and thermal performance of mainstream in battery cooling of hybrid electric vehicles
The novel concept of impinging jet cooling, i.e., an active-passive air cooling strategy, was proposed to achieve improved battery thermal management in hybrid vehicles, and this method is supported by excess high pressure discharged air. To comprehensively realize the active-passive combined cooling behavior, a rectangular channel with a jet impingement hole was utilized to experimentally and num
Single item self-rated general health : SF-36 based observations from 16,910 spine surgery procedures
Purpose: In spine surgery single item patient-reported outcome assessment has been used for many years. Items 1 and 2 of SF-36 are used for assessment of general health. We used these items to explore single item, self-rated, general health assessment after spine surgery. Methods: Patients operated for lumbar disc herniation or lumbar spinal stenosis between 2007 and 2017, were recruited from the
Corporate ESG reporting quantity, quality and performance : Where to now for environmental policy and practice?
Environmental, social and governance (ESG) issues are driving corporate strategy and performance. However, does this mean more ESG reporting is being done? If so, is the quality of ESG reports improving? And what about ESG performance? In this paper, we examine these three trends in ESG reporting—quantity, quality and corporate ESG performance. With a Swedish multinational corporate focus, we anal
X-Pro : Distributed XDP Proxies Against Botnets of Things
The steadily increasing Internet of Things (IoT) devices are vulnerable to be used as bots to launch distributed-denial-of-service (DDoS) attacks. In this paper, we present X-Pro, a distributed XDP proxy to counteract DDoS attacks. We propose a source-based defense mechanism where proxies located between the IoT devices and the victim performs flow policing on all IoT traffic from a single adminis
Longitudinal Doppler Assessments in Late Preterm Fetal Growth Restriction
Purpose To assess the longitudinal variation of the ratio of umbilical and cerebral artery pulsatility index (UCR) in late preterm fetal growth restriction (FGR). Materials and Methods A prospective European multicenter observational study included women with a singleton pregnancy, 32 +0-36 +6, at risk of FGR (estimated fetal weight [EFW] or abdominal circumference [AC] 40 percentile points). The
Lifting with simple gadgets and applications to circuit and proof complexity
We significantly strengthen and generalize the theorem lifting Nullstellensatz degree to monotone span program size by Pitassi and Robere (2018) so that it works for any gadget with high enough rank, in particular, for useful gadgets such as equality and greater-than. We apply our generalized theorem to solve three open problems: •We present the first result that demonstrates a separation in proof
KRW composition theorems via lifting
One of the major open problems in complexity theory is proving super-logarithmic lower bounds on the depth of circuits (i.e., mathrm{P} nsubseteq text{NC}{1}). Karchmer, Raz, and Wigderson [13] suggested to approach this problem by proving that depth complexity behaves'as expected' with respect to the composition of functions f diamond g. They showed that the validity of this conjecture would impl

Introducing Norm Creative Perspectives in Engineering and Design Educations
The design of technologies, built environments, products, or services can result in inequalities, exclusion, and discrimination, possibly because designers–often unintentionally–reproduce social norms through their designs. This strongly relates to engineering and design educations, preparing future professionals and contributing to sustainable societies. The aim of this paper is to introduce and

Circulating lipids and breast cancer prognosis in the Malmö diet and cancer study
Purpose: Examine the association between circulating lipids and breast cancer outcomes in patients enrolled in the Malmö Diet and Cancer Study (MDCS). Patients and methods: Circulating lipid levels were measured in blood sampled upon enrollment in the female MDCS cohort (N = 17,035). We identified all MDCS participants with incident invasive breast cancer diagnosed between 1991 and 2014. Follow-up
