Activins are dimeric glycoproteins belonging to the transforming growth factor beta superfamily and resulting from the assembly of two beta subunits, which may also be combined with alpha subunits to form inhibins. Activins were discovered in 1986 following the isolation of inhibins from porcine follicular fluid, and were characterized as ovarian hormones that stimulate follicle stimulating hormone (FSH) release by the pituitary gland. In particular, activin A was shown to be the isoform of greater physiological importance in humans. Read More

Determination of Rheumatoid Factors by ELISA.

Methods Mol Biol 2019 ;1901:263-270

Department of Autoimmunology, Statens Serum Institut, Copenhagen, Denmark.

IgM and IgA autoantibodies binding to IgG are called rheumatoid factors (RFs) and occur with high frequency in rheumatoid arthritis (RA) and with lower frequency in other autoimmune diseases. RFs have diagnostic and prognostic value in RA, but they also have a high potential to cause false positive reactions in other immunoassays, especially sandwich assays. For these reasons it is imperative to be able to measure RFs in serum samples from patients suspected of RA or other autoimmune diseases and in serum samples to be analyzed by sandwich immunoassay for various clinical parameters.

Genes known to escape X chromosome inactivation predict co-morbid chronic musculoskeletal pain and posttraumatic stress symptom development in women following trauma exposure.

Am J Med Genet B Neuropsychiatr Genet 2018 Dec 11. Epub 2018 Dec 11.

Institute for Trauma Recovery, University of North Carolina, Chapel Hill, North Carolina.

Co-morbid chronic musculoskeletal pain (CMSP) and posttraumatic stress symptoms (PTSS) are frequent sequelae of motor vehicle collision, are associated with greater disability than either outcome alone, and are more prevalent in women than men. In the current study we assessed for evidence that gene transcripts originating from the X chromosome contribute to sex differences in vulnerability to CMSP and PTSS after motor vehicle collision. Nested samples were drawn from a longitudinal study of African American individuals, and CMSP (0-10 numeric rating scale) and PTSS (impact of events scale, revised) outcomes were assessed 6 months following motor vehicle collision.

Abatacept initiation in rheumatoid arthritis and the risk of cancer: a population-based comparative cohort study.

Rheumatology (Oxford) 2018 Dec 7. Epub 2018 Dec 7.

Centre for Clinical Epidemiology, Lady Davis Institute, Jewish General Hospital, Montréal, Québec, Canada.

Objective: To assess whether abatacept as initial biological DMARD (bDMARD) in the treatment of RA, when compared with other bDMARDs, is associated with an increased risk of cancer overall and by specific cancer sites (breast, lung, lymphoma, melanoma and non-melanoma skin cancer).

Methods: We performed a population-based cohort study among patients newly treated with bDMARDs within the US-based Truven MarketScan population and Supplemental US Medicare from 2007 to 2014. Cox proportional hazards models were used to estimate hazard ratios and 95% CIs of any cancer (and specific cancers) associated with initiation of abatacept, compared with initiation of other bDMARDs, adjusted for age and deciles of the propensity score.

DICAM Attenuates Experimental Colitis via Stabilizing Junctional Complex in Mucosal Barrier.

Inflamm Bowel Dis 2018 Dec 9. Epub 2018 Dec 9.

Division of Gastroenterology, Department of Internal Medicine, School of Medicine, Kyungpook National University, Daegu, Korea.

Background: Adhesion molecules maintain the intestinal barrier function that is crucial to prevent intestinal inflammation. Dual immunoglobulin domain-containing adhesion molecule (DICAM) has been recently identified and known for the involvement in cell-cell adhesion through homophilic interaction and heterophilic interaction with integrin αVβ3. We tested whether the change of DICAM expression affects the severity of colonic inflammation. Read More

Musculoskeletal ultrasound as a biomarker of remission - results from a one-year prospective study in patients with rheumatoid arthritis.

Med Ultrason 2018 Dec;20(4):453-460

Medical University of Plovdiv, Medical Faculty, Department of Propedeutic of Internal Diseases; University Hospital "Kaspela'', Rheumatology Clinic.

Aims: To assess the role of musculoskeletal ultrasound (MSUS) as a biomarker of remission and to compare the rates of clinical and imaging remission in patients with rheumatoid arthritis (RA) on different types of treatment.

Material And Methods: One hundred and forty-one patients underwent physical and ultrasound examination at 5 visits (at baseline and after 1, 3, 6 and 12 months). Patients were divided into two groups according to the type of treatment, which involved synthetic (sDMARDs) and biologic (bDMARDs) disease-modifying antirheumatic drugs. Read More

Granulocyte-macrophage colony-stimulating factor receptor expression in clinical pain disorder tissues and role in neuronal sensitization.

Pain Rep 2018 Sep-Oct;3(5):e676. Epub 2018 Sep 17.

Peripheral Neuropathy Unit, Centre for Clinical Translation, Department of Medicine, Hammersmith Hospital, Imperial College London, London, United Kingdom.

Introduction: Granulocyte-macrophage colony-stimulating factor receptor (GM-CSFR) is highly expressed in peripheral macrophages and microglia, and is involved in arthritis and cancer pain in animal models. However, there is limited information on GM-CSFR expression in human central nervous system (CNS), peripheral nerves, or dorsal root ganglia (DRG), particularly in chronic pain conditions.

Objectives: Immunohistochemistry was used to quantify GM-CSFR expression levels in human tissues, and functional sensory effects of GM-CSF were studied in cultured DRG neurons. Read More

Pseudotumor and Subsequent Implant Loosening as a Complication of Revision Total Hip Arthroplasty with Ceramic-on-Metal Bearing: A Case Report.

Hip Pelvis 2018 Dec 6;30(4):276-281. Epub 2018 Dec 6.

Department of Orthopaedics, Korea University Guro Hospital, Seoul, Korea.

Pseudotumors are not uncommon complications after total hip arthroplasty (THA) and may occur due to differences in bearing surfaces of the head and the liner ranging from soft to hard articulation. The most common causes of pseudotumors are foreign-body reaction, hypersensitivity and wear debris. The spectrum of pseudotumor presentation following THA varies greatly-from completely asymptomatic to clear implant failure. Read More
