Prospective Study on Diagnostic Performance of Color Doppler Ultrasound Using Trans-stenotic Mean Arterial Pressure Gradient as a Reference in Stented Superior Mesenteric Artery

Background: The aim of this study was to evaluate the diagnostic performance of color Doppler ultrasound (CDU) after stenting of superior mesenteric artery (SMA) stenosis using mean arterial pressure (MAP) gradients as a reference method. Methods: This is a prospective study. Thirty-one patients underwent 51 paired measurements of MAP gradients and CDU after endovascular intervention with endopros

Vacuum-assisted wound closure and permanent onlay mesh–mediated fascial traction : A Novel Technique for the Prevention of Incisional Hernia after Open Abdomen Therapy Including Results From a Retrospective Case Series

Background and Aims: Incisional hernia development is a frequent long-term sequel after open abdomen treatment. This report describes a novel technique, the vacuum-assisted wound closure and permanent onlay mesh–mediated fascial traction for temporary and final closure of the open abdomen, with the intention to decrease incisional hernia rates. Primary aim was to evaluate incisional hernia develop

Cystatin C and creatinine-based eGFR levels and their correlation to long-term morbidity and mortality in older adults

Background: The prevailing diagnostic criteria for CKD are age-independent, but have been challenged in light of the eGFR decline associated with normal aging. The stages of CKD communicate magnitude of risk of ESRD, cardiovascular morbidity, and mortality. Aims: This study aims to provide more insight into the morbidity and mortality associated with eGFR levels corresponding to the current CKD st

Omission of doxorubicin from the treatment of stage II-III, intermediate-risk Wilms' tumour (SIOP WT 2001) : an open-label, non-inferiority, randomised controlled trial

BACKGROUND: Before this study started, the standard postoperative chemotherapy regimen for stage II-III Wilms' tumour pretreated with chemotherapy was to include doxorubicin. However, avoidance of doxorubicin-related cardiotoxicity effects is important to improve long-term outcomes for childhood cancers that have excellent prognosis. We aimed to assess whether doxorubicin can be omitted safely fro

Assignment of vibrational spectral bands of kidney tissue by means of low temperature SERS spectroscopy

Surface enhanced Raman scattering (SERS) spectroscopy is a useful method for detection of trace amounts of molecules. It has already been successfully implemented for detection of explosives, food additives, biomarkers in blood or urine, etc. In the last decade, SERS spectroscopy was introduced into the field of health sciences and has been especially focused on early disease detection. In the rec

Extreme diversification of floral volatiles within and among species of Lithophragma (Saxifragaceae)

A major challenge in evolutionary biology is to understand how complex traits of multiple functions have diversified and codiversified across interacting lineages and geographic ranges. We evaluate intra- and interspecific variation in floral scent, which is a complex trait of documented importance for mutualistic and antagonistic interactions between plants, pollinators, and herbivores. We perfor

A polynomial formulation of adaptive strong stability preserving multistep methods

A new formulation of explicit multistep methods allows variable step-sizes by construction. This formulation can be used to construct time-adaptive strong stability preserving (SSP) multistep methods of any order for the solution of time-dependent PDEs. The new formulation is implemented in a MATLAB package, and some numerical examples are presented.

Remission from Alcohol Use Disorder among males in the Lundby Cohort during 1947-1997

Background. Alcohol use disorders are a major health problem, often with a chronic course. Studies on remission from alcohol use disorders are sparse. Objective. The aim of this study was to analyse the rate of remission from AUD and the possible influence of other mental disorders and sociodemographic factors on the remission in the Lundby Cohort. Method. Remission from AUD was studied for 312 ma

Targeted proteomics of hip articular cartilage in OA and fracture patients

Osteoarthritis (OA) is a common chronic disease, causing joint pain and reduced physical function. OA progresses slowly over a period of several years; to avoid an exacerbation of symptoms, it is critical to able to diagnose the disease as early as possible. The identification of disease-specific biomarkers may enable such an early diagnosis. The aim of this study was to investigate potential biom

Bacterial conversion of depolymerized Kraft lignin

BackgroundLignin is a potential feedstock for microbial conversion into various chemicals. However, the microbial degradation rate of native or technical lignin is low, and chemical depolymerization is needed to obtain reasonable conversion rates. In the current study, nine bacterial strains belonging to the Pseudomonas and Rhodococcus genera were evaluated for their ability to grow on alkaline-tr

Impact of the morphological and chemical properties of copper-zirconium-SBA-15 catalysts on the conversion and selectivity in carbon dioxide hydrogenation

A hybrid catalyst consisting of Zr-doped mesoporous silica (Zr-SBA-15) supports with intergrown Cu nanoparticles was used to study the effects of a catalyst’s chemical states on CO2 hydrogenation. The chemical state of the catalyst was altered by using tetraethyl orthosilicate (TEOS) or sodium metasilicate (SMS) as the silica precursor in the synthesis of the Zr-SBA-15 framework, and infiltration A hybrid catalyst consisting of Zr-doped mesoporous silica (Zr-SBA-15) supports with intergrown Cu nanoparticles was used to study the effects of a catalyst’s chemical states on CO2 hydrogenation.

Variability in functional outcome and treatment practices by treatment center after out-of-hospital cardiac arrest : analysis of International Cardiac Arrest Registry

Purpose: Functional outcomes vary between centers after out-of-hospital cardiac arrest (OHCA) and are partially explained by pre-existing health status and arrest characteristics, while the effects of in-hospital treatments on functional outcome are less understood. We examined variation in functional outcomes by center after adjusting for patient- and arrest-specific characteristics and evaluated

Examiners ‘assessment criteria in dissertations and the learning outcomes of doctoral education

Swedish dissertations are public, followed by closedassessment committee meetings that only report pass-failvotes. 166 external examiners from 72 doctoral dissertationswere therefore anonymously surveyed for their views on passfail norms, scientific standard of theses and candidates and theacademic independence of the assessed candidate. They werealso asked to relate their assessment to the nation

Assessment of neurocognitive function after cardiac arrest

PURPOSE OF REVIEW: Impaired neurocognitive function is common in cardiac arrest survivors and the use of specific neurocognitive assessments are recommended in both clinical trials and daily practice. This review examines the most recent evidence to guide in the selection of neurocognitive outcome assessment tools after cardiac arrest. RECENT FINDINGS: Neurocognitive impairment after cardiac arres

Bombus terrestris in a mass-flowering pollinator-dependent crop : A mutualistic relationship?

Bumblebees (Bombus spp.) rely on an abundant and diverse selection of floral resources to meet their nutritional requirements. In farmed landscapes, mass-flowering crops can provide an important forage resource for bumblebees, with increased visitation from bumblebees into mass-flowering crops having an additional benefit to growers who require pollination services. This study explores the mutuali

BEESCOUT : A model of bee scouting behaviour and a software tool for characterizing nectar/pollen landscapes for BEEHAVE

Social bees are central place foragers collecting floral resources from the surrounding landscape, but little is known about the probability of a scouting bee finding a particular flower patch. We therefore developed a software tool, BEESCOUT, to theoretically examine how bees might explore a landscape and distribute their scouting activities over time and space. An image file can be imported, whi
