Musculoskeletal diseases such as rheumatoid arthritis are complex multifactorial disorders that are chronic in nature and debilitating for patients. A number of drug families are available to clinicians to manage these disorders but few tests exist to target these to the most responsive patients. As a consequence, drug failure and switching to drugs with alternate modes of action is common. In parallel, a limited number of laboratory tests are available which measure biological indicators or 'biomarkers' of disease activity, autoimmune status, or joint damage. There is a growing awareness that assimilating the fields of drug selection and diagnostic tests into 'companion diagnostics' could greatly advance disease management and improve outcomes for patients. This review aims to highlight: the current applications of biomarkers in rheumatology with particular focus on companion diagnostics; developments in the fields of proteomics, genomics, microbiomics, imaging and bioinformatics and how integration of these technologies into clinical practice could support therapeutic decisions.

A "Round, Bruising Sort of Pain": Autistic Girls' Social Camouflaging in Inclusive High School Settings.

J Autism Dev Disord

January 2025

Department of Special Education, Peabody College, Vanderbilt University, 110 Magnolia Circle, Nashville, TN, 37212, USA.

Although autistic females often "camouflage" their autism, few studies examine the degree to which adolescent females demonstrate these behaviors in inclusive school settings. We examined: (a) the nature, extent, and underlying motivation of camouflaging in high school; (b) the extent to which autistic girls' characteristics related to camouflaging settings, people, benefits, costs, and school supports; and (c) how girls' open-ended descriptions agreed with closed-ended camouflaging ratings. Using quantitative and qualitative analyses, this study examined the extent, domains, costs, and benefits of autistic females' school-based camouflaging.

Clinicopathologic and genomic characteristics of biliary tract carcinomas with TERT promoter mutations among East Asian population.

Department of Pathology and Translational Genomics, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, South Korea; Center for Companion Diagnostics, Precision Medicine Research Institute, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, South Korea. Electronic address:

Telomerase reverse transcriptase gene promoter (TERT) mutations are biomarkers that predict survival and responses to immune checkpoint inhibitors in various malignancies. However, their prevalence and clinicopathologic characteristics in biliary tract carcinomas are largely unknown. We performed a comprehensive genomic profiling of formalin-fixed paraffin-embedded tumor tissue from 485 carcinomas, including intrahepatic (n = 220), perihilar (n = 54), distal biliary tract (n = 110), and gallbladder (n = 101) cancers, using next-generation sequencing.

Development of a brief screening measure of unmet supportive care needs (SCNS-P&C-6) in caregivers of people with high-grade glioma.

J Patient Rep Outcomes

January 2025

Psycho-Oncology Cooperative Research Group, School of Psychology, Faculty of Science, The University of Sydney, Camperdown, NSW, 2006, Australia.

Purpose: Informal caregivers of people with high grade glioma (HGG) often have high levels of unmet support needs. Routine screening for unmet needs can facilitate appropriate and timely access to supportive care. We aimed to develop a brief screening tool for HGG caregiver unmet needs, based on the Supportive Care Needs Survey-Partners & Caregivers (SCNS-P&C).
