Diffusion‐Weighted Imaging for the Evaluation of the Sacroiliac Joint in Pediatric Patients

Arthritis Care &Research, EarlyView.
Objective Maturational signal in the sacroiliac joint (SIJ) of skeletally immature youth is often misinterpreted as inflammation. Diagnostic tools that improve specificity are greatly needed. Apparent diffusion coefficient (ADC) values from diffusion‐weighted imaging (DWI), when used with standard imaging, may enhance diagnostic accuracy.

Role of Prednisone and 25‐Hydroxyvitamin D on Bone Mineral Density and Osteoporosis in Systemic Lupus Erythematosus

Arthritis Care &Research, EarlyView.
Objective We evaluated the role of 25‐hydroxyvitamin D (25[OH]D), prednisone, and other risk factors for bone mineral density (BMD) loss and osteoporosis in systemic lupus erythematosus (SLE). Methods We calculated the association between 25(OH)D levels and other potential risk factors and BMD measures (spine T scores) and osteoporosis (defined as a T ...

The Earth as a living planet: human-type diseases in the earthquake preparation process [PDF]

, 2013
The new field of complex systems supports the view that a number of systems arising from disciplines as diverse as physics, biology, engineering, and economics may have certain quantitative features that are intriguingly similar.

The temporal trends and short‐ and long‐term mortality of people with acute myocardial infarction and rheumatoid arthritis: a nationwide cohort study

Arthritis Care &Research, Accepted Article.
Aims We investigated whether a diagnosis of rheumatoid arthritis (RA) affects the quality of inpatient acute myocardial infarction (AMI) care and long‐term mortality post‐AMI. Methods We analysed data from 784,091 adults, 6,047 with a diagnosis of RA, from England and Wales hospitalised with AMI between 2005 and 2019 from the MINAP registry, linked ...

The influence of toughening-particles in CFRPs on low velocity impact damage resistance performance

, 2014
The role of particle-toughening for increasing impact damage resistance in carbon fibre reinforced polymer (CFRP) composites was investigated. Five carbon fibre reinforced systems consisting of four particle-toughened matrices and one system containing ...

Stochastic Metallic-Glass Cellular Structures Exhibiting Benchmark Strength [PDF]

, 2008
By identifying the key characteristic “structural scales” that dictate the resistance of a porous metallic glass against buckling and fracture, stochastic highly porous metallic-glass structures are designed capable of yielding plastically and inheriting

Associations of Sleep and Shift Work with Osteoarthritis Risk

Arthritis Care &Research, Accepted Article.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships between circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000‐person cohort, we evaluated associations between sleep duration, sleeplessness/insomnia, and ...

In situ study of fracture behavior of ultrafine WC–Co cemented carbide

Materials Research Letters, 2017
The fracture behavior of ultrafine WC–Co cemented carbide was demonstrated by in situ tensile tests in a transmission electron microscope. Using two kinds of cemented carbide samples with and without previously introduced microcracks, the process from ...
