Self-management Elucidates How Practicing Physical Exercises Influences the Health Related Quality of Life of Independently Dwelling Older Adults.

According to active aging theory, self-management plays a pivotal role for well-being of older adults as they navigate the aging process. The current quasi-experimental study, employing a between-within design, examines the impact of guided group physical training on changes in self-management and its subsequent effect on quality of life among a sample of independently living old adults. We assessed balance, strength, mobility, self-management, and quality of life were among 149 older adults (123 females, 26 males), mean age = 77.

Soluble ST2 and CXCL-10 may serve as biomarkers of subclinical diastolic dysfunction in SLE and correlate with disease activity and damage.

Objective: Subclinical myocardial dysfunction has been reported to occur early in systemic lupus erythematous (SLE). The study aim was to search for biomarkers of subclinical myocardial dysfunction which may correlate with disease activity in SLE patients.

Methods: This is a prospective, controlled, cross-sectional study of 57 consecutive patients with SLE and 18 controls.

Potassium tert-Amylate: A Cautionary Tale.

Potassium tert-amylate ( t-AmylOK) is a well-known, commercially available base and generally regarded as a more solvent-soluble form of potassium tert-butoxide ( t-BuOK). However, despite the structural similarity between the tert-butyl and amyl moieties, potassium tert-amylate in toluene can undergo distinct physical property changes in the presence of protic solvents that warrant further consideration. This is particularly surprising given that t-AmylOH is a byproduct of deprotonation with t-AmylOK, as well as the fact that its structurally similar relative, t-BuOK, is commercially available in t-BuOH.

Expression levels of selected genes can predict individual rheumatoid arthritis patient response to tumor necrosis factor alpha blocker treatment.

Objectives: Rheumatoid arthritis (RA) patients have many therapeutic options; however, tools to predict individual patient response are limited. The Genefron personal diagnostic kit, developed by analyzing large datasets, utilizes selected interferon stimulated gene expressions to predict treatment response. This study evaluates the kit's prediction accuracy of individual RA patients' response to tumor necrosis alpha (TNFα) blockers.

Objective: The aim of this study was to evaluate the presence of autoantibodies to cyclic citrullinated synthetic peptides (ACPAs) in the sputum of patients with long-standing rheumatoid arthritis (RA).

Methods: Nineteen consecutive RA patients and 16 age- and sex-matched control subjects participated in this cross-sectional study. All underwent complete lung function tests and provided induced sputum.

Kinetic Modeling of the Nickel-Catalyzed Esterification of Amides.

Nickel-catalyzed coupling reactions provide exciting tools in chemical synthesis. However, most methodologies in this area require high catalyst loadings, which commonly range from 10-20 mol % nickel. Through an academic-industrial collaboration, we demonstrate that kinetic modeling can be used strategically to overcome this problem, specifically within the context of the Ni-catalyzed conversion of amides to esters.

Prevalence of Axial Spondyloarthritis Among Patients With Fibromyalgia: A Magnetic Resonance Imaging Study With Application of the Assessment of SpondyloArthritis International Society Classification Criteria.

Objective: To evaluate the prevalence of sacroiliitis, the radiographic hallmark of inflammatory spondyloarthropathy, among patients diagnosed with fibromyalgia syndrome (FMS), using the current Assessment of SpondyloArthritis International Society (ASAS) criteria and magnetic resonance imaging.

Methods: Patients experiencing FMS (American College of Rheumatology 1990 criteria) were interviewed regarding the presence of spondyloarthritis (SpA) features and underwent HLA-B27 testing, C-reactive protein (CRP) level measurement, and magnetic resonance imaging examinations of the sacroiliac joints. FMS severity was assessed by the Fibromyalgia Impact Questionnaire and the Short Form 36 health survey.

Impaired diffusion tensor imaging findings in the corpus callosum and cingulum may underlie impaired learning and memory abilities in systemic lupus erythematosus.

Background: Memory impairment is prevalent in systemic lupus erythematosus (SLE); however, its pathogenesis is unknown. In a previous functional magnetic resonance imaging (fMRI) study we demonstrated altered brain activity dynamics and less brain deactivation in patients with SLE as compared with healthy controls, when performing a learning and memory task. Our findings localized this impairment to the default mode network (DMN), and particularly to its anterior medial prefrontal cortex node.

Longterm Efficacy of an Antipneumococcal Polysaccharide Vaccine among Patients with Autoimmune Inflammatory Rheumatic Diseases.

Objective: To estimate the longterm humoral response of an antipneumococcal polysaccharide vaccine (PPSV23) in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), or inflammatory bowel disease (IBD)-associated spondyloarthropathy (SpA), and the effect of demographic and clinical factors and treatment on the longterm efficacy of the vaccine.

Methods: A total of 145 consecutive patients treated with biologics [tumor necrosis factor-α (TNF-α) or interleukin 6 (IL-6) receptor inhibitors] or methotrexate (MTX) participated in this study. Fifteen were excluded because of absent information regarding their vaccination status (n = 9) or because of technical problems in obtaining their serum sample (n = 6).

Influenza vaccination is safe and effective in patients suffering from fibromyalgia syndrome.

The fibromyalgia syndrome (FMS) is considered to result from the exposure of a genetically susceptible individual to various triggers, such as physical trauma, stress, viral infections etc. A possible role of vaccination in FMS etiology has been suspected. Our objective was to evaluate the efficacy and safety of influenza vaccination in FMS patients.

Immunogenicity and safety of vaccination against seasonal 2012 influenza virus among patients with psoriatic arthritis and psoriasis.

Objectives: We aimed to assess the immunogenicity and safety of vaccination against seasonal influenza in psoriatic arthritis (PsA) and psoriasis (Pso) patients.

Methods: Patients with PsA or Pso and healthy controls were vaccinated with the Sanofi Pasteur vaccine recommended by the WHO in 2012. Clinical and laboratory assessments were performed on the day of the vaccination and 4-6 weeks later.

Galectin-3 is a sensor-regulator of toll-like receptor pathways in synovial fibroblasts.

Galectin-3 is a β-galactoside-binding lectin that plays an important role in the modulation of immune responses. It has been shown to aggravate joint inflammation and destruction in experimental arthritis. We investigated the role of galectin-3 in TLR-induced cell activation in human synovial fibroblasts (SF) in order to better understand the mechanism(s) of the proinflammatory function of galectin-3 in arthritis.

Decreased diffusion capacity on lung function testing in asymptomatic patients with systemic lupus erythematosus does not predict future lung disease.

Background: In a previous study performed 9 ± 3.6 years ago, 74 asymptomatic patients with systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS) underwent lung function testing. A significantly low diffusion capacity (DLCO) ranging from 45% to 70% was recorded in 28 of the 74 (37.

Results: Nine male and 6 female patients, aged 33 ± 12 years, mean disease duration 9 years (range: 1-25) were identified.

Discovery of ABT-267, a pan-genotypic inhibitor of HCV NS5A.

We describe here N-phenylpyrrolidine-based inhibitors of HCV NS5A with excellent potency, metabolic stability, and pharmacokinetics. Compounds with 2S,5S stereochemistry at the pyrrolidine ring provided improved genotype 1 (GT1) potency compared to the 2R,5R analogues. Furthermore, the attachment of substituents at the 4-position of the central N-phenyl group resulted in compounds with improved potency.

Learning and memory-related brain activity dynamics are altered in systemic lupus erythematosus: a functional magnetic resonance imaging study.

Background: Memory impairment is prevalent in systemic lupus erythematosus (SLE); however, the pathogenesis is unknown.

Methods: We studied 12 patients with SLE without clinically overt neuropsychiatric manifestations and 11 matched healthy controls, aiming to characterize neural correlates of memory impairment, using structural and functional magnetic resonance imaging (MRI). The paradigm consisted of three encoding and free-recall cycles, allowing characterization of dynamics along consecutive retrieval attempts.

Acute calcific band keratopathy: case report and literature review.

Unlabelled: An 86-year-old patient developed a significant intraocular inflammatory reaction after having phacoemulsification. Topical therapy did not eliminate the inflammation, and tissue plasminogen activator (tPA) was injected into the anterior chamber. A white corneal plaque appeared in the previously clear cornea within days of the injection.

"Trap" the diagnosis: a man with recurrent episodes of febrile peritonitis, not just familial Mediterranean fever.

Monogenic periodic fever syndromes are characterized by recurrent episodes of fever, accompanied by localized inflammatory manifestations. Among them, familial Mediterranean fever (FMF) is the most studied and is by far the most prevalent periodic fever syndrome in Israel. We present a diagnostic workup of a patient suffering from a periodic fever syndrome, initially thought to be FMF and characterized by attacks of fever, severe abdominal pain, a migratory erythematous rash and conjunctivitis.

Inside out: a neuro-behavioral signature of free recall dynamics.

Free recall (FR) is a ubiquitous internally-driven retrieval operation that crucially affects our day-to-day life. The neural correlates of FR, however, are not sufficiently understood, partly due to the methodological challenges presented by its emerging property and endogenic nature. Using fMRI and performance measures, the neuro-behavioral correlates of FR were studied in 33 healthy participants who repeatedly encoded and retrieved word-lists.
