This gap is further limited by the underreporting of sex-disaggregated outcomes in clinical trials and observational studies. This review synthesizes current evidence on sex differences in treatment efficacy and drug persistence in PsA, with attention to variation across therapeutic drug classes. Potential mechanisms contributing to differential treatment response are explored, including differences in disease characteristics, comorbidities, pain perception, adiposity, pharmacokinetics, immune and inflammatory factors, and gender-related sociocultural factors.

Musculoskeletal ultrasound (MSUS) and magnetic resonance imaging (MRI) provide complementary, noninvasive methods for visualizing inflammatory and structural pathology across these tissue domains. This review summarizes current evidence supporting the use of MSUS and MRI in the diagnosis and management of PsA, with emphasis on clinically relevant applications, and briefly discusses emerging molecular and advanced imaging techniques. We discuss the role of MSUS in early disease detection, differential diagnosis, evaluation of dactylitis and enthesitis, assessment of disease activity and remission, and guidance of treatment decisions in routine practice, and review the role of MRI with a focus on the evaluation of axial involvement and deep inflammatory and structural changes not accessible by ultrasound. Practical considerations, including scanning protocols, contextual factors affecting interpretation, and emerging scoring systems, are highlighted.

Reduced capillary density (<7 capillaries/mm) and \"Active/Late\" scleroderma patterns, consistently predicted disease progression. Low capillary density and both \"Active\" and \"Late\" scleroderma patterns were strongly associated with more severe skin fibrosis, digital ulcers and calcinosis, pulmonary (arterial) hypertension and interstitial lung disease. A lowered capillary density further predicted major cardiovascular events and gastrointestinal dysmotility, and linked with subclinical renal vasculopathy. In Early SSc, \"Active\" or \"Late\" patterns increased the probability of progression to definite SSc.
