SwedeAmp—the Swedish Amputation and Prosthetics Registry : 8-year data on 5762 patients with lower limb amputation show sex differences in amputation level and in patient-reported outcome

Background and purpose — For want of national guidelines for lower limb amputation (LLA) the quality registry SwedeAmp was started in 2011 to increase knowledge around LLA and prosthetic rehabilitation. We now present data from the first 8 years of registration. Patients and methods — We present descriptive data from the first 8 years (2011–2018) of registration. Patient-reported outcome was colle

Modeling and quality assessment of nystagmus eye movements recorded using an eye-tracker

Mathematical modeling of nystagmus oscillations is a technique with applications in diagnostics, treatment evaluation, and acuity testing. Modeling is a powerful tool for the analysis of nystagmus oscillations but quality assessment of the input data is needed in order to avoid misinterpretation of the modeling results. In this work, we propose a signal quality metric for nystagmus waveforms, the

Commercial albumin solution enhances endotoxin-induced vasoplegia and inflammation

BACKGROUND: The Gram-negative bacterium Escherichia coli, commonly involved in severe sepsis and septic shock, shed endotoxin that upon detection by the host triggers an inflammatory cascade. Efficiency of albumin solutions to restore hypovolemia during sepsis has been debated. To aid identification of subgroups of sepsis patients that may respond positively or negatively to treatment with albumin

Risk assessment in PAH using quantitative CMR tricuspid regurgitation : relation to heart catheterization

AIMS: Improved risk stratification is of value for decision making in pulmonary arterial hypertension (PAH). Right heart catheterization combined with quantitative tricuspid regurgitation (TR) by cardiovascular magnetic resonance (CMR) may provide this. The aims were to study: (i) to what extent quantitative TR is associated with event-free survival; (ii) how quantitative TR is related to known pr

Organ-Restricted Vascular Delivery of Nanoparticles for Lung Cancer Therapy

Nanoparticle-based targeted drug delivery holds promise for treatment of cancers. However, most approaches fail to be translated into clinical success due to ineffective tumor targeting in vivo. Here, the delivery potential of mesoporous silica nanoparticles (MSN) functionalized with targeting ligands for epidermal growth factor receptor and C─C chemokine receptor type 2 is explored in lung tumors

Kinetic investigations of combustion of small oxygenated aliphatic hydrocarbons – modeling and experiments

The depletion of oil reserves and the increasingly stringent European Union regulation of air pollution have forced researchers and manufacturers to search for cleaner and sustainable substitutes to petroleum‐based transportation fuels. Biofuels like small aliphatic alcohols are of increasing interest as alternatives to fossil fuels, as they offer long‐term fuel‐source regenerability. As major adv

Recent advances of PET imaging in clinical radiation oncology

Radiotherapy and radiation oncology play a key role in the clinical management of patients suffering from oncological diseases. In clinical routine, anatomic imaging such as contrast-enhanced CT and MRI are widely available and are usually used to improve the target volume delineation for subsequent radiotherapy. Moreover, these modalities are also used for treatment monitoring after radiotherapy.

Psychometric properties of the WHOQOL-BREF among next of kin to older persons in nursing homes

Background: The worries of next of kin about their older loved ones in nursing homes can be extensive and can adversely affect their subjective experiences of their own physical, mental and social well-being. It is thus of utmost importance to measure the quality of life of next of kin in a valid and reliable way. Methods: The design is a cross-sectional study with psychometric evaluation based on

Lack of PCSK6 Increases Flow-Mediated Outward Arterial Remodeling in Mice

Proprotein convertases (PCSKs) process matrix metalloproteases and cytokines, but their function in the vasculature is largely unknown. Previously, we demonstrated upregulation of PCSK6 in atherosclerotic plaques from symptomatic patients, localization to smooth muscle cells (SMCs) in the fibrous cap and positive correlations with inflammation, extracellular matrix remodeling and cytokines. Here,

Non-invasive respiratory support for the management of transient tachypnea of the newborn

BACKGROUND: Transient tachypnea of the newborn (TTN) is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Supportive management might be sufficient. Non-invasive (i.e. without endotracheal intubation) respiratory support may, however, be administered to reduce respiratory distres

Functional movement compensations persist in individuals with hip osteoarthritis performing the five times sit-to-stand test 1 year after total hip arthroplasty

BACKGROUND: Methods to quantify and evaluate function are important for development of specific rehabilitation interventions. This study aimed to evaluate functional movement compensation in individuals with hip osteoarthritis performing the five times sit-to-stand test and change following total hip arthroplasty. To this end, trajectories of the body's center of mass in the medial-lateral and ant

Biotechnological Potential of Bdellovibrio and Like Organisms and Their Secreted Enzymes

Bdellovibrio and like organisms (BALOs) are obligate predatory bacteria that selectively prey on a broad range of Gram-negative bacteria, including multidrug-resistant human pathogens. Due to their unique lifestyle, they have been long recognized as a potential therapeutic and biocontrol agent. Research on BALOs has rapidly grown over the recent decade, resulting in many publications concerning mo

Impact of Multiple Injection Strategies on Efficiency and Combustion Characteristics in an Optical PPC Engine

Partially premixed combustion (PPC) is a promising way to achieve high thermal efficiency and low emissions, especially by using multiple injection strategies. The mechanisms behind PPC efficiency are still to be explained and explored. In this paper, multiple injections have been used to affect the gross indicated efficiency in an optical PPC engine modified from a Volvo MD13 heavy-duty diesel en
