Given the high prevalence of chronic kidney disease and the impact of renal fibrosis on the prognosis of these patients, there is a need for novel diagnostic tools to be able to detect pathological changes earlier and thus avoid progression to later stages of the disease.
Researchers from University North Carolina, Chapel Hill have discovered prostate-specific member antigen (PSMA)-targeted agents with reduced salivary gland uptake while maintaining high tumor uptake. Synthesis and subsequent screening of PSMA agents bearing different chelators and targeting ligands led to the identification of two lead agents, NOTA-UNC-PSMA-2 and DOTA-UNC-PSMA-2.
It seems unlikely that American poet and civil rights activist Maya Angelou spent much time thinking about translational research. But two quotes of hers capture the essence of the interplay between bench and bedside: “I did then what I knew how to do. Now that I know better, I do better” and “I’ve learned that I still have a lot to learn.” At the 2023 Annual Congress of the European Academy of Neurology, Mary Reilly described the relationship between bench and bedside as “a continuous circle of translation,” with each cycle beginning with patients and their needs.
Because of its overexpression in many solid tumors, gastrin-releasing peptide receptor (GRPR) represents a promising therapeutic target and imaging marker for cancer. Gastrin-releasing peptide (GRP) and bombesin are the natural ligands for GRPR. To improve in vivo stability, researchers at the University of British Columbia synthesized two 68Ga-labeled GRPR agonists by replacing Val and His sequences in GPR(20-27) and bombesin(7-14) with Tle and NMe-His, respectively.
The fibroblast activation protein (FAP) is a known biomarker expressed on the surface of cancer-associated fibroblasts (CAF), as well as an important target that distinguishes normal fibroblasts from CAF. Researchers from National Yang-Ming University recently reported the discovery and preclinical evaluation of a novel PET tracer, [18F]FEQGP, being developed for the detection of FAB expression in CAF imaging.
Four-repeat (4R)-tauopathies are neurodegenerative diseases whose main hallmarks are brain accumulations of specific protein tau isoforms that lead to syndromes such as progressive supranuclear palsy (PSP) or corticobasal syndrome. There are yet no sensitive-enough PET tracers for 4R-tauopathies.
Precision diagnostics company Inoviq Ltd.’s stock soared 44% on the news that its breast cancer diagnostic, SubB2M/CA15-3, detected all stages of breast cancer with 87% accuracy, 81% sensitivity and 93% specificity. The clinical validation study that included 483 samples outperformed the standard of care CAS15-3 test, demonstrating an area under the curve (AUC) of .93 compared to .70.
The U.K. government created a new £21 million ($US26.55 million) fund to accelerate the roll out of artificial intelligence (AI) diagnostics and treatment tools across the NHS. The AI Diagnostic Fund will enable hospitals to bid for funding to speed up the deployment of the most promising AI imaging and decision support tools to help patients with cancers, strokes and heart conditions.
The U.S. Office of Inspector General (OIG) has concluded an analysis that found fault with Medicare payments for genetic testing under CPT code 81408, a code that covers tests for a variety of mutations of medical interest. According to OIG, these claims were often paid $2,000 each despite poor oversight from Medicare administrative contractors (MACs), raising the risk that a substantial percentage of roughly $888 million in claims paid between 2018 and 2021 were either fraudulent or at best inappropriate.
