Methods: The ASAS-perSpA study data were analysed. Models for the three patient groups were run separately to explore factors associated with HRQoL and GH, assessed by EQ-5D and ASAS-HI, respectively.

The effects of physical exercise on axial spondyloarthritis - a systematic review.

Aim: To collect and summarize the available scientific evidence that evaluates the effects of physical exercise interventions on axial spondyloarthritis (axSpA).

Methods: A systematic review was conducted in accordance to the guidance of Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) to collect randomized controlled trials on the PubMed, Embase and Web of Science Core Collection databases. The search strategy included terms regarding physical exercise interventions targeted to axSpA participants and all of its variants in multiple combinations adapted to each one of the databases regarding its own special requirements.

In a community-based setting spondyloarthritis patients report higher levels of physical disability than chronic low back pain patients - results from EpiReuma.pt.

Objectives: Chronic low back pain (CLBP) is a common health problem and in most patients it is not possible to identify a specific cause (non-specific CLBP). Spondyloarthritis is a musculoskeletal disorder characterized by (often inflammatory) back pain and spinal stiffness. The impact of CLBP and spondyloarthritis on patients' physical function may be different.

Relations between short-term memory and the within-subject variability of experimental pain intensity reports: Results from healthy and Fibromyalgia patients.

While factors contributing to between-subjects differences in pain have been studied extensively, factors contributing to the within-subjects variability of pain reports are yet unexplored. The aim of this investigation was to assess possible associations between short-term memory and the within-subjects variability of pain reports in healthy and chronic pain patients. Healthy participants were recruited at the University of Haifa, Israel, and Fibromyalgia patients were recruited at a rheumatology department in a central hospital in Lisbon, Portugal.

Health-related quality of life among spondyloarthritis and chronic low back pain patients: results from a nationwide population-based survey.

Purpose: Both spondyloarthritis and chronic low back pain (CLBP) significantly impact health-related quality of life (HRQoL). It is important to clarify whether these disorders have different impacts on the several domains of HRQoL as different mechanisms may necessitate different treatment interventions. Moreover, the factors associated with HRQoL can inform more targeted group interventions to promote HRQoL.

Methotrexate: Implications of pharmacogenetics in the treatment of patients with Rheumatoid Arthritis.

Background: Methotrexate (MTX) is an anti-folate drug with anti-proliferative and anti-inflammatory effects. MTX proved to be the most highly effective, fast-acting disease modifying anti-rheumatic drug (DMARD), being widely used for the treatment of rheumatoid arthritis (RA). This review aims to describe the main genetic variants identified concerning proteins that play a role in methotrexate's kinetics and efficiency profile.

The role of muscle in the susceptibility and progression of axial Spondyloarthritis: The MyoSpA Study Protocol.

Background: Axial Spondyloarthritis (axSpA) is a chronic, inflammatory rheumatic disease that affects the axial skeleton, causing pain, stiffness, and fatigue. Genetics and environmental factors such as microbiota and microtrauma are known causes of disease susceptibility and progression. Murine models of axSpA found a decisive role for biomechanical stress as an inducer of enthesitis and new bone formation.

Muscle dysfunction in axial spondylarthritis: the MyoSpA study.

Objectives: We aimed to investigate muscle physical properties, strength, mass, physical performance, and the prevalence of sarcopenia in patients with axial spondylarthritis (axSpA) compared to the healthy controls (HC).

Methods: We performed a cross-sectional study on 54 participants: 27 patients with axSpA and 27 HC, matched by age, gender, and level of physical activity. Muscle physical properties (stiffness, tone and elasticity), muscle strength (five-times sit-to-stand [5STS] test), muscle mass, physical performance (measured through gait speed) and sarcopenia were compared between the groups.

Identification of clinical phenotypes of peripheral involvement in patients with spondyloarthritis, including psoriatic arthritis: a cluster analysis in the worldwide ASAS-PerSpA study.

Objective: To identify clusters of peripheral involvement according to the specific location of peripheral manifestations (ie, arthritis, enthesitis and dactylitis) in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), and to evaluate whether these clusters correspond with the clinical diagnosis of a rheumatologist.

Methods: Cross-sectional study with 24 participating countries. Consecutive patients diagnosed by their rheumatologist as PsA, axial SpA or peripheral SpA were enrolled.

Biobanks for aging research - perceptions and choices among rheumatology outpatients.

Objective: Biobanks for research (BBR) have enormous value for research, including those specifically oriented to chronic diseases. Knowing public attitudes and perceptions is key to design and implement patient-centered BBR. We assessed patient awareness, perception and choices among rheumatology outpatients regarding aging biobanking activities.

Direct tissue-sensing reprograms TLR4 Tfh-like cells inflammatory profile in the joints of rheumatoid arthritis patients.

CD4 T cells mediate rheumatoid arthritis (RA) pathogenesis through both antibody-dependent and independent mechanisms. It remains unclear how synovial microenvironment impinges on CD4 T cells pathogenic functions. Here, we identified a TLR4 follicular helper T (Tfh) cell-like population present in the blood and expanded in synovial fluid.

Development of an environmental contextual factor item set relevant to global functioning and health in patients with axial spondyloarthritis.

Objective: To describe the development of an Environmental contextual factors (EF) Item Set (EFIS) accompanying the disease specific Assessment of SpondyloArthritis international Society Health Index (ASAS HI).

Method: First, a candidate item pool was developed by linking items from existing questionnaires to 13 EF previously selected for the International Classification of Functioning, Disability and Health (ICF) /ASAS Core Set. Second, using data from two international surveys, which contained the EF item pool as well as the items from the ASAS HI, the number of EF items was reduced based on the correlation between the item and the ASAS HI sum score combined with expert opinion.

The Effect of and Polymorphisms on Skeletal Muscle Performance in Axial Spondyloarthropathies.

Background: Spondyloarthritis (SpA) are the most common group of chronic inflammatory rheumatic diseases affecting about 1.5% of the adult Caucasian population. Low back pain is the most common symptom.

Lumbar myofascial physical properties in healthy adults: myotonometry vs. shear wave elastography measurements.

Objective: The human resting myofascial tone maintains the body tone in a neutral posture, the assessment of this and other muscle physical properties (MPP) is relevant, since, it is altered in many pathological states.

Patients And Methods: Seventeen healthy subjects (8 males), between 18-50 years old, were assessed. The MPP of lower lumbar muscles was evaluated on right and left sides during prone resting position using two devices; myotonometry (stiffness, elasticity and tone) and ultrasound-based shear-wave elastography (SWE) (shear modulus).

New Insights into Immunological Involvement in Congenital Disorders of Glycosylation (CDG) from a People-Centric Approach.

Congenital disorders of glycosylation (CDG) are rare diseases with variable phenotypes and severity. Immunological involvement remains a largely uncharted topic in CDG, mainly due to lack of robust data. To better characterize immune-related manifestations' prevalence, relevance, and quality-of-life (QoL) impact, we developed electronic questionnaires targeting (1) CDG patients and (2) the general "healthy" population.
