Disease Activity Score on 28 Joints and Polypharmacy Are Independent Predictors for Health-Related Quality of Life Evaluated by INCAVISA in Patients With Rheumatoid Arthritis.

Objective: The aim of this study was to investigate the main factors associated to a diminished health-related quality of life (HRQoL) evaluated by INCAVISA (Health-Related Quality of Life Inventory for Latin American Patients) in patients with rheumatoid arthritis (RA).

Methods: Female, 18 years or older, RA (American College of Rheumatology 1987 criteria and American College of Rheumatology/European League against Rheumatism 2010 criteria) patients who attended the outpatient rheumatology department of the Hospital Civil "Dr. Juan I.

Serum leptin and serum leptin/serum leptin receptor ratio imbalance in obese rheumatoid arthritis patients positive for anti-cyclic citrullinated peptide antibodies.

Introduction: Leptin has a prominent role in the development and maintenance of acute and chronic inflammatory states such as rheumatoid arthritis (RA) and obesity. Nevertheless, the association of serum leptin (sLep) and soluble leptin receptor (sLepR) in RA pathogenesis has not been clarified. The purpose of this study was to evaluate the association of sLep, sLepR and leptin production indexes such as sLep/fat mass ratio with clinical activity and biomarkers and anti-cyclic citrullinated peptide (anti-CCP) antibodies in RA compared with body mass index (BMI) matched control subjects.

Efficacy of a vaccine formula against tuberculosis in cattle.

"Test-and-slaughter" has been successful in industrialized countries to control and eradicate tuberculosis from cattle; however, this strategy is too expensive for developing nations, where the prevalence is especially high. Vaccination with the Calmette-Guérin (BCG) strain has been shown to protect against the development of lesions in vaccinated animals: mouse, cattle and wildlife species. In this study, the immune response and the pathology of vaccinated (BCG-prime and BCG prime-CFP-boosted) and unvaccinated (controls) calves were evaluated under experimental settings.

Inhibitors of MAPK pathway ERK1/2 or p38 prevent the IL-1{beta}-induced up-regulation of SRP72 autoantigen in Jurkat cells.

Phosphorylation is the most important post-translational event at a cellular level that is regulated by protein kinases. MAPK is a key player in the important cellular signaling pathway. It has been hypothesized that phosphorylation might have a role in the induction of break tolerance against some autoantigens such as SRP72.
