OBJECTIVE: Shared epitope (SE)-coding DRB1 alleles are associated with bone erosion in several diseases, including rheumatoid arthritis (RA) and periodontal disease (PD), but the underlying mechanism is unknown. We have recently identified the SE as an osteoclast-activating ligand. To better understand the biological effects of the SE in vivo, here we sought to determine whether it can facilitate spontaneous bone damage in naïve mice. METHODS: 3-month old naïve transgenic mice that carry the human SE-coding allele DRB1*04:01, or a SE-negative allele DRB1*04:02 were studied...

BACKGROUND: Rheumatic diseases, irrespective of etiology and clinical course, influence different areas of a patient's life. Adapting to disability and limitations caused by an illness is very difficult for many patients. The main goal of a therapeutic procedure should be improvement of health-related quality of life (QoL). OBJECTIVE: Evaluation of the factors that influence the QoL that are conditioned by the state of health of patients with osteoarthritis (OA) and rheumatoid arthritis (RA)...

INTRODUCTION: The early years are a critical period in a child's health and development, yet most preschool children fail to meet physical activity guidelines. Outside of the home and neighbourhood, children spend a large proportion of time within early childhood education and care (ECEC) services such as long day care. Research is required to determine how the design of day care outdoor (and indoor) spaces provides opportunities or constraints for physical activity. A significant evidence gap surrounds what objectively measured attributes of the home and neighbourhood environment influence preschoolers' physical activity...

OBJECTIVES: Patient's and physician's perspective can differ in rheumatoid arthritis (RA). The aim was to define the concept of patient-reported flares. METHODS: Post-hoc analysis of a randomized controlled trial of a step-down strategy in RA patients treated with anti-TNF, in DAS28-remission for ≥6 months, randomized to either "spacing" or "maintaining" anti-TNF. The occurrence of patient-reported flares (PRF) was evaluated every 3 months for 18 months by: "Over the last 3 months, did you experience symptoms suggestive of disease exacerbation?"...

Symptomatic skeletal events (SSEs) commonly occur in patients with bone metastases, often leading to hospitalisations and decreased quality-of-life. In the ALSYMPCA trial, radium-223 significantly improved overall survival (hazard ratio 0.70, 95% confidence interval [CI] 0.58-0.83, P < 0.001) and prolonged time to first SSE (hazard ratio 0.66, 95% CI 0.52-0.83, P = 0.00037) and subsequent SSE (hazard ratio 0.65, 95% CI 0.51-0.83, P = 0.00039) versus placebo in patients with castration-resistant prostate cancer with symptomatic bone metastases and no known visceral metastases...

OBJECTIVE: Creating transmural linear lesions on the beating heart is an important component of minimally invasive surgical ablation for atrial fibrillation. Animal studies have shown poor efficacy for surface bipolar radiofrequency ablation (RFA). Clinicians have developed strategies including multiple device applications and vena caval occlusion (VCO) to improve ablation efficacy. These techniques were evaluated in an acute porcine model. METHODS: In the first experiment, an RFA device was used to perform two 40-second epicardial ablations on the right atrium of six pigs...

Immunosuppressive drugs have been used in the treatment of multiple sclerosis (MS) for a long time. Today, the increased number of approved substances and the possibility of an oral availability of some immunomodulators improve the therapeutic repertory and increase patient satisfaction and compliance. Teriflunomide is indicated as first line oral disease modifying therapy (DMT) in relapsing-remitting MS (RRMS). Its immunosuppressive capacity results from an inhibition of de novo pyrimidine synthesis in rapidly proliferating lymphocytes...

Vitamin D, a molecular precursor of the potent steroid hormone calcitriol, has a crucial functions and roles in physiology and pathophysiology. Tellingly, Calcitriol has been shown to regulate various cellular signalling networks and cascades that have crucial role in cancer biology and diagnostics. Mounting lines of evidences from previous clinical and preclinical investigations indicate that the deficiency of vitamin D may contribute to the carcinogenesis risk. Concomitantly, recent reports suggested that significant reduction in the cancer occurrence and progression is more likely to appear after vitamin D supplementation...

In this issue of Structure, Gingras et al. (2016) show that Ras association (RA) domains of the Rap1 and Ras interacting protein Rasip1 can form a dimer in the presence and absence of the small G protein Rap1. This provides an explanation for the observed complex formation in Rap1-mediated signaling.

CC chemokine receptor 2 (CCR2) is one of 19 members of the chemokine receptor subfamily of human class A G-protein-coupled receptors. CCR2 is expressed on monocytes, immature dendritic cells, and T-cell subpopulations, and mediates their migration towards endogenous CC chemokine ligands such as CCL2 (ref. 1). CCR2 and its ligands are implicated in numerous inflammatory and neurodegenerative diseases including atherosclerosis, multiple sclerosis, asthma, neuropathic pain, and diabetic nephropathy, as well as cancer...
