Studies have identified abnormalities in the microbiota of patients with arthritis. To evaluate the pathogenicity of human microbiota, we performed fecal microbial transplantation from children with spondyloarthritis and controls to germ-free KRN/B6xNOD mice. Ankle swelling was equivalent in those that received patient vs. control microbiota. Principal coordinates analysis revealed incomplete uptake of the human microbiota with over-representation of two genera (Bacteroides and Akkermansia) among the transplanted mice...

BACKGROUND: Published methods for quantification of magnetic resonance imaging (MRI) evidence of inflammation in the sacroiliac joint lack validation in pediatric populations. We evaluated the reliability and construct validity of the Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joint inflammation score (SIS) in children with suspected or confirmed juvenile spondyloarthritis (JSpA). METHODS: The SPARCC SIS measures the presence, depth, and intensity of bone marrow inflammation on MRI through the cartilaginous part of the joint...

Erythema ab igne (EAI) is a cutaneous finding caused by prolonged heat exposure and is characterized by a reticular, brownish-pigmented, often telangiectatic dermatosis. The eruption is reminiscent of livedo reticularis, which is typically seen in the setting of a number of rheumatologic conditions, most prominently vasculitis. Identification of key features distinguishing EAI from livedo reticularis can aid in the diagnosis of EAI and correct elucidation of the underlying etiology. Our patient presented with heating pad-induced EAI in the setting of chronic pain...

Genome-wide association analysis advanced understanding of blood pressure (BP), a major risk factor for vascular conditions such as coronary heart disease and stroke. Accounting for smoking behavior may help identify BP loci and extend our knowledge of its genetic architecture. We performed genome-wide association meta-analyses of systolic and diastolic BP incorporating gene-smoking interactions in 610,091 individuals. Stage 1 analysis examined ∼18.8 million SNPs and small insertion/deletion variants in 129,913 individuals from four ancestries (European, African, Asian, and Hispanic) with follow-up analysis of promising variants in 480,178 additional individuals from five ancestries...

Many shelters euthanize or restrict adoptions for dogs that exhibit food guarding while in the animal shelter. However, previous research showed that only half the dogs exhibiting food guarding during an assessment food guard in the home. So, dogs are often misidentified as future food guarders during shelter assessments. We examined the impact of shelters omitting food guarding assessments. Nine shelters conducted a two-month baseline period of assessing for food guarding followed by a two-month investigative period during which they omitted the food guarding assessment...

The pediatric rheumatic diseases are a heterogeneous group of rare diseases, posing a number of challenges for the use of traditional clinical and translational research methods. Innovative comparative effectiveness approaches are needed to efficiently study treatment strategies and disease outcomes. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed the consensus treatment plan (CTP) approach as a comparative effectiveness tool for research in pediatric rheumatology. CTPs are treatment strategies, developed by consensus methods among CARRA members, intended to reduce variation in treatment approaches, standardize outcome measurements, and allow for comparison of the effectiveness of different approaches with the goal of improving disease outcomes...

Pigment-Dispersing Factor (PDF) is an important neuropeptide in the brain circadian network of Drosophila and other insects, but its role in bees in which the circadian clock influences complex behaviour is not well understood. We combined high-resolution neuroanatomical characterizations, quantification of PDF levels over the day and brain injections of synthetic PDF peptide to study the role of PDF in the honey bee Apis mellifera We show that PDF co-localizes with the clock protein Period (PER) in a cluster of laterally located neurons and that the widespread arborizations of these PER/PDF neurons are in close vicinity to other PER-positive cells (neurons and glia)...

PURPOSE OF REVIEW: This review aims to provide an update on the use of imaging in the assessment of juvenile spondyloarthritis (JSpA) disease manifestations. RECENT FINDINGS: Recent studies have demonstrated superior reliability and specificity of MRI for assessment of sacroiliac joint inflammation compared with radiography. The use of gadolinium contrast may not add incremental value to the assessment of inflammatory sacroiliitis. Sacroiliitis is common at diagnosis of spondyloarthritis...
