Genetic Risk Loci in Fibromyalgia
Researchers examined genetic data drawn from 11 different worldwide cohorts, that included from more than 2.5 million adults, of which 55,000 had been diagnosed with fibromyalgia. They identified DNA sequence variants in 26 regions of the genome that affect the risk of developing fibromyalgia. Many of the genes implicated in these regions are involved in brain and nerve function. This is the largest fibromyalgia GWAS to date.

Uricase-Targeted Therapies in Gout
In most mammals, uricase catalyzes the oxidation of uric acid to allantoin, a highly soluble compound easily excreted by the kidneys. But humans lack functional uricase, leaving xanthine oxidase inhibitors (allopurinol/febuxostat) as first-line urate-lowering therapy (ULT). Uricase-based biologics are reserved for uncontrolled/refractory gout patients with gouty flares, active synovitis, and/or non-resolving tophi despite optimized oral ULT.

The Wider Implications of Dactylitis
Dactylitis, AKA the "sausage digit", is a hallmark of psoriatic arthritis (PsA), but as Possemato and colleagues point out, it is fundamentally a clinical sign, and not a diagnosis. This review article discusses the wider implications of dactylitis in rheumatology and medicine underscores the diagnostic and prognostic significance of this manifestation.

Fibromyalgia: Diagnosis and Management
Fibromyalgia (FM) affects 4–6% of the U.S. population, with nearly a 2 fold female predominance. Nociplastic pain underlies the pathophysiology of FM. CNS hypersensitization to both painful and non-painful stimuli occurs with little or no tissue pathology. Framing FM as a disorder of CNS processing is critical to diagnosis, treatment approaches and patient buy-in.

Psoriatic Arthritis: EULAR 2026 Recap
Years of IL-17 vs. IL-23 debate in PsA finally got tested head-to-head: bimekizumab outperformed risankizumab on joint outcomes in the BE BOLD trial, while a GLP-1 combination study suggests weight and metabolic status are active drivers of PsA — not just comorbidities. This recap also digs into early signals that biologic choice may influence whether psoriasis progresses to PsA, and why some well-controlled patients are still in pain.

ACP Position Paper on Dietary Supplements
More than half of U.S. adults use dietary supplements, yet only a quarter use supplements recommended by a healthcare professional, and current law lets supplements reach the market with no premarket safety evaluation, unlike drugs or food additives.
