Photoacoustic (PA) imaging is an emerging non-invasive diagnostic modality with many potential clinical applications in oncology, rheumatology and the cardiovascular field. For this purpose, there is a high demand for exogenous contrast agents with high absorption coefficients in the optical window for tissue imaging, i.e. the near infrared (NIR) range between 680 and 950 nm. We herein report the photoacoustic properties of quinone-fused porphyrins inserted with different transition metals as new highly promising candidates...

REVIEW
Michael DE Potter, Marjorie M Walker, Nicholas J Talley
Non-coeliac gluten or wheat sensitivity (NCG/WS) is a condition characterised by adverse gastrointestinal and/or extra-intestinal symptoms associated with the ingestion of gluten- or wheat-containing foods, in the absence of coeliac disease or wheat allergy. Up to one in 100 people in Australia may have coeliac disease but many more report adverse gastrointestinal and/or extra-intestinal symptoms after eating wheat products. In the absence of validated biomarkers, a diagnosis of NCG/WS can only be made by a double-blind, placebo-controlled, dietary crossover challenge with gluten, which is difficult to apply in clinical practice...

Scientific publishing, including in the field of Rheumatology, is evolving rapidly. Predatory journals are one of the major threats to contemporary publishing, especially to eager and naïve authors. In this narrative review, we discuss mechanisms that authors can employ to white list genuine scientific journals and blacklist "predatory" ones. Inclusion of a journal in reputed indices such as Medline (but not just Pubmed), Web of Science, Scopus or Embase raises the likelihood that the journal is genuine, more so if it is included in the current Journal Citation Reports...

History and clinical findings We present a 31-year old woman with a 6-year history of cutaneous lupus erythematosus (CLE) who presented to the emergency room with typical chest pain. ECG and transthoracic echocardiography were normal. Her working diagnosis of pericarditis was made due to systemic progression of her lupus erythematosus (LE). Treatment with NSAIDs was initiated and her immunosuppressive regimen intensified. The patient was discharged after resolution of her symptoms. A week later, the patient was seen at the rheumatology clinic with recurrence and aggravation of her symptoms...

Evidence has emerged about the relationship between atopic dermatitis (AD) and autoimmune diseases, but the underlying mechanism of this association is complex and still unclear. Recent epidemiological data from the published work suggest a positive correlation. The aim of this review is to analyze the frequency of co-occurrence of AD and autoimmune diseases. Our systematic review included 22 articles from PubMed describing the reciprocal association between AD and autoimmune diseases. Although not all the studies achieved statistically significant results, patients suffering from autoimmune diseases involving skin and intestinal mucosa, such as vitiligo, alopecia areata, celiac disease and inflammatory bowel diseases, showed a higher risk to have AD as comorbidity...

REVIEW

Biosimilars are products that contain a similar version of the active substance of an already authorized original biologic medicinal product (reference medicinal product). Their development requires special consideration, as similarity to the reference agent needs to be established through a comprehensive comparability exercise. Given the complex nature of these agents, minor structural differences may emerge, but the process of biosimilarity determination is designed to ascertain that the nature and impact of these differences are not clinically significant...

The emergence of chikungunya virus in the Americas means the affected population is at risk of developing severe, chronic, rheumatologic disease, even months after acute infection. Accurate diagnostic methods for past infections are essential for differential diagnosis and consequence management. This study evaluated three commercially-available chikungunya Immunoglobulin G immunoassays by comparing them to an in-house Enzyme-Linked ImmunoSorbent Assay conducted by the Centers for Disease Control and Prevention (Atlanta, Georgia, United States)...

Pericardial effusions are not uncommon in rheumatoid arthritis (RA); however, they are rarely the presenting symptom of the disease. We describe a 55-year-old female who presented to the emergency department with complaints of chest pain and dyspnea on exertion. Initial workup revealed a medium-sized pericardial effusion. The wide spectrum of etiologies, including infectious and non-infectious disease, was explored. Eventually, after ruling out an array of disease states, rheumatologic workup was positive for RA...

OBJECTIVE: Among the challenges in conducting clinical trials in large-vessel vasculitis (LVV), including both giant cell arteritis (GCA) and Takayasu arteritis (TA), is the lack of standardized and meaningful outcome measures. The Outcome Measures in Rheumatology (OMERACT) Vasculitis Working Group initiated an international effort to develop and validate data-driven outcome tools for clinical investigation in LVV. METHODS: An international Delphi exercise was completed to gather opinions from clinical experts on LVV-related domains considered important to measure in trials...

BACKGROUND: Flare-ups in juvenile idiopathic arthritis (JIA) are characterized by joint pain and swelling and often accompanied with fatigue, negative emotions, and reduced participation in activities. To minimize the impact of JIA on the physical and psychosocial development and well-being of young people (YP), it is essential to regularly monitor disease activity and side effects, as well as to support self-management such as adherence to treatment plans and engagement in general health-promoting behaviors...

Inflammatory rheumatic diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) show a striking female predominance ranging from 3:1 in RA up to 9:1 in SLE. The background for those gender bias is not fully understood yet, but seems to be the result of a complex interaction between sex hormones, (epi-)genetics, and possibly even the composition of gut microbiota. Moreover, time of disease onset, the clinical phenotype including co-morbidities as well as the course of the diseases during life differ between genders...

In November 2016, the American College of Physicians (ACP) published a clinical practice guideline on the management of acute and recurrent gout. This guideline differs substantially from the latest guidelines generated by the American College of Rheumatology (ACR), European League Against Rheumatism (EULAR) and 3e (Evidence, Expertise, Exchange) Initiative, despite reviewing largely the same body of evidence. The Gout, Hyperuricemia and Crystal-Associated Disease Network (G-CAN) convened an expert panel to review the methodology and conclusions of these four sets of guidelines and examine possible reasons for discordance between them...

OBJECTIVES: SB4 (Benepali, Brenzys) is a biosimilar of reference etanercept (ETN). In a randomised, double-blind, 52-week study, SB4 demonstrated comparable efficacy and safety to ETN in patients with rheumatoid arthritis (RA). The open-label extension period evaluated long-term efficacy, safety and immunogenicity when continuing SB4 versus switching from ETN to SB4. METHODS: In the randomised, double-blind phase, patients received weekly subcutaneous administration of 50 mg SB4 or ETN with background methotrexate for up to 52 weeks...

Whether a reaction to events in the clinical arena, a consequence of technological innovation, or the legitimization of the marked ethos in health care, the field of medical ethics has become a complex domain in our time. Indeed, the ubiquity of ethical dilemmas in the provision of health care is well documented with more than 99% of primary care physicians reporting ethical problems arising in the conduct of their practices (1-3). Although commentary relating to this domain has most often originated in the primary care setting, hospital-based medicine and its ethics committees are another fertile source, as is medical research...

Chikungunya fever has become a relevant public health problem in countries where epidemics occur. Until 2013, only imported cases occurred in the Americas, but in October of that year, the first cases were reported in Saint Marin island in the Caribbean. The first autochthonous cases were confirmed in Brazil in September 2014; until epidemiological week 37 of 2016, 236,287 probable cases of infection with Chikungunya virus had been registered, 116,523 of which had serological confirmation. Environmental changes caused by humans, disorderly urban growth and an ever-increasing number of international travelers were described as the factors responsible for the emergence of large-scale epidemics...
