Knee replacement revision: an international comparison

AbstractBackground and purpose: The need for knee replacement revision arises from a combination of patient, prosthesis and surgeon factors. Registry data can help study these relationships. Pooling data from multiple registries may increase both reliability and generalizability. The study aim was to gain a multi-national overview of knee replacement revision, to inform best-practice and improve o

Entering non-platformized sectors: The co-evolution of legitimacy debates and platform business models in digital health care

Digital platforms have deeply transformed a wide variety of sectors. However, new platform business models often face critical legitimacy challenges. Consequently, new entrants must continuously design and redesign their business model components, particularly when entering non-platformized sectors that are highly regulated. We draw on a longitudinal case study of the emergence of digital healthca

This article provides an overview of the Belt and Road Initiative’s (BRI) current progress, as well as the challenges and uncertainties it faces on the national and international level. At the same time, it notes that the Chinese Communist Party continues to show resilience in its promotion of the initiative. Finally, it argues that we will likely see the BRI develop in new, experimental ways in t

Zoledronic Acid Targeting of the Mevalonate Pathway Causes Reduced Cell Recruitment and Attenuates Pulmonary Fibrosis

Background and aim: Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease causing irreparable scarring of lung tissue, with most patients succumbing rapidly after diagnosis. The mevalonate pathway, which is involved in the regulation of cell proliferation, survival, and motility, is targeted by the bisphosphonate zoledronic acid (ZA). The aim of this study was to assess the antifibroti

Innate Immune Responses to RSV Infection Facilitated by OGG1, an Enzyme Repairing Oxidatively Modified DNA Base Lesions

The primary cause of morbidity and mortality from infection with respiratory syncytial virus (RSV) is the excessive innate immune response(s) (IIR) in which reactive oxygen species (ROS) play key role(s). However, the mechanisms for these processes are not fully understood. We hypothesized that expressions of IIR genes are controlled by the ROS-generated epigenetic-like mark 7,8-dihydro-8-oxo(d)gu

Towards a treatment for mitochondrial disease : current compounds in clinical development

Primary mitochondrial diseases are a heterogeneous group of rare genetic disorders affecting approximately 125 persons per million. Mutations underlying these diseases give rise to biological changes (including decrease in cellular energy production and increase in reactive oxygen species), leading to organ failure, and commonly early morbidity. Mitochondrial diseases often present in early childh

Challenges imposed by the COVID-19 pandemic on the Obstetrics and Gynecology residency program : a mixed-methods Swedish survey in the COPE Staff cohort study

BACKGROUND: To outline how the training program and work situation of residents in Obstetrics and Gynecology (OB-GYN) was affected by the pandemic and to illuminate how residents experienced these changes.METHODS: As part of the COVID-19 in Pregnancy and Early Childhood Staff (COPE Staff) cohort study, between January and May 2021, all participating residents were invited to answer a 28-question o

IRF8 deficiency induces the transcriptional, functional, and epigenetic reprogramming of cDC1 into the cDC2 lineage

Conventional dendritic cells (cDCs) consist of two major functionally and phenotypically distinct subsets, cDC1 and cDC2, whose development is dependent on distinct sets of transcription factors. Interferon regulatory factor 8 (IRF8) is required at multiple stages of cDC1 development, but its role in committed cDC1 remains unclear. Here, we used Xcr1-cre to delete Irf8 in committed cDC1 and demons

Predictors of Safety Climate Outcomes in Firefighting

Safety climate refers to the perceived value an organization places on safety at a specific point in time. To determine key predictors of safety climate in the fire service, we distributed a questionnaire to 105 career firefighters in a Swedish city of approximately 110,000 and analyzed their responses. We used these data to investigate the role of individual, work-group, and organizational factor

A hybrid type I, multi-center randomized controlled trial to study the implementation of a method for Sustained cord circulation And VEntilation (the SAVE-method) of late preterm and term neonates : a study protocol

BACKGROUND: An intact umbilical cord allows the physiological transfusion of blood from the placenta to the neonate, which reduces infant iron deficiency and is associated with improved development during early childhood. The implementation of delayed cord clamping practice varies depending on mode of delivery, as well as gestational age and neonatal compromise. Emerging evidence shows that infant

The usability of ClimApp : A personalized thermal stress warning tool

ClimApp was developed to assist individuals in reducing the risk of exposure to thermal stress and to supply the user with individualized advice and recommendations. The tool integrates several human thermal models and heat indices with the local weather forecast and goes on to provide users with a prediction of their thermal stress based on their activity level, clothing level, and heat acclimati

A hydrodynamic comparisons of two different high-pressure homogenizer valve design principles : A step towards increased efficiency

Designing more efficient high-pressure homogenizers (HPHs) is important from an industrial perspective (reduce energy cost). Understanding the relationship between valve geometry and breakup is interesting from an emulsification research perspective. Typically, two different design principles are used for commercial HPHs: the traditional outward radial flow design and the newer inward radial flow

Identification of Nordic Berries with Beneficial Effects on Cognitive Outcomes and Gut Microbiota in High-Fat-Fed Middle-Aged C57BL/6J Mice

High-fat diets are associated with neuronal and memory dysfunction. Berries may be useful in improving age-related memory deficits in humans, as well as in mice receiving high-fat diets. Emerging research has also demonstrated that brain health and cognitive function may be related to the dynamic changes in the gut microbiota. In this study, the impact of Nordic berries on the brain and the gut mi

Heparin-binding protein in ventilator-induced lung injury

Background: Although mechanical ventilation is often lifesaving, it can also cause injury to the lungs. The lung injury is caused by not only high pressure and mechanical forces but also by inflammatory processes that are not fully understood. Heparin-binding protein (HBP), released by activated granulocytes, has been indicated as a possible mediator of increased vascular permeability in the lung

The influence of foramina on femoral neck fractures and strains predicted with finite element analysis

Hip fractures following a low-impact fall are common in the elderly. Finite element (FE) models of the proximal femur can improve the prediction of fracture risk over current clinical standards. Foramina in the femoral neck may influence its fracture mechanics, albeit the majority of FE modelling approaches do not consider them. This study aimed to show how foramina affect fracture propagation and

Rethinking refurbishment projects for improved users' working environment

The built environment is important to achieve a sustainable society. From a sustainability perspective, refurbishment can be preferable to building anew. A significant proportion of the built environment needs to be refurbished. Refurbishment projects also provide the opportunity to proactively upgrade the working environment for users during operation and use.Research concerning the working envir

Multi-Armed Bandits in Brain-Computer Interfaces

The multi-armed bandit (MAB) problem models a decision-maker that optimizes its actions based on current and acquired new knowledge to maximize its reward. This type of online decision is prominent in many procedures of Brain-Computer Interfaces (BCIs) and MAB has previously been used to investigate, e.g., what mental commands to use to optimize BCI performance. However, MAB optimization in the co
