The role of diet in hyperuricemia and gout
Purpose of review Although gout's cardinal feature is inflammatory arthritis, it is closely associated with insulin resistance and considered a manifestation of the metabolic syndrome. As such, both gout and hyperuricemia are often associated with major cardiometabolic and renal comorbidities that drive the persistently elevated premature mortality rates among gout patients. To that end, conventional low-purine (i.e., low-protein) dietary advice given to many patients with gout warrant reconsideration. Recent findings Recent research suggests that several healthy diets, such as the Mediterranean or Dietary Appro...

Adherence to gout guidelines: where do we stand?
Purpose of review Although gout is a common, well-recognized, and extensively researched rheumatologic disease, it continues to be underappreciated and undertreated. Although the prevalence of gout has been rising over the past several decades, adherence to urate lowering therapy continues to be suboptimal. Recent studies have underscored the potential success of guideline-directed therapy. Recent findings Adherence to gout treatment continues to be suboptimal according to multinational metaanalyses. Moreover, studies measuring adherence are prone to overestimation and each methodologic approach has intrinsic li...

Racial, ethnic, and healthcare disparities in rheumatoid arthritis
Purpose of review This review highlights the available data describing racial and ethnic health disparities among patients with rheumatoid arthritis in the United States from an epidemiological, disease activity, and wider socioeconomic standpoint. Recent findings Despite centralized government initiatives to include more underrepresentative minority populations into research, many of the studies that examined rheumatoid arthritis still fail to include sizeable cohorts of races or ethnic groups other than whites. Evidence is slowly mounting that individual, provider, and system-level barriers exist and contribut...

Recent advances in targeted drug delivery for treatment of osteoarthritis
Purpose of review Osteoarthritis is associated with severe joint pain, inflammation, and cartilage degeneration. Drugs injected directly into intra-articular joint space clear out rapidly providing only short-term benefit. Their transport into cartilage to reach cellular targets is hindered by the tissue's dense, negatively charged extracellular matrix. This has limited, despite strong preclinical data, the clinical translation of osteoarthritis drugs. Recent work has focused on developing intra-joint and intra-cartilage targeting drug delivery systems (DDS) to enable long-term therapeutic response, which is presented ...

Role of adipose tissues in osteoarthritis
Purpose of review Epidemiologic studies reveal that the link between obesity and osteoarthritis cannot be uniquely explained by overweight-associated mechanical overload. For this reason, much attention focuses on the endocrine activity of adipose tissues. In addition to the systemic role of visceral and subcutaneous adipose tissues, many arguments highlight the involvement of local adipose tissues in osteoarthritis. Recent findings Alteration in MRI signal intensity of the infrapatellar fat pad may predict both accelerated knee osteoarthritis and joint replacement. In this context, recent studies show that mese...

Posttraumatic osteoarthritis: what have we learned to advance osteoarthritis?
Purpose of review Current thinking in the study of posttraumatic osteoarthritis (PTOA) is overviewed: the osteoarthritis which follows acute joint injury. The review particularly highlights important publications in the last 18 months, also reflecting on key older literature, in terms of what have we have we learned and have yet to learn from PTOA, which can advance the osteoarthritis field as a whole. Recent findings PTOA is a mechanically driven disease, giving insight into mechanical drivers for osteoarthritis. A mechanosensitive molecular tissue injury response (which includes activation of pain, degradative...

The transition from enthesis physiological responses in health to aberrant responses that underpin spondyloarthritis mechanisms
Purpose of review Despite immunology and translational therapeutics advances in inflammatory arthritis over the past two decades, the enthesis, which is the epicentric of the spondyloarthritis family pathological process, retains many mysteries because of tissue inaccessibility that hampers direct immune study. As entheses are subject to almost continuous mechanical stress and spondyloarthritis is linked to microdamage or injury and joint stress, it is cardinal to understand the physiological changes occurring within the entheses not only to be able to differentiate disease from health but also to understand the transi...
