A Cox-Based Framework for Quantile Estimation

Quantile regression (QR) provides a flexible framework for characterizing conditional distributions and can offer useful insights for quantile estimation. In this paper, we provide intuition for the interpretation of QR by highlighting the approach that it is a reparameterization...

Pediatric Mental Health Integration and Perceived Quality of Care

OBJECTIVE: This study examined how access to behavioral and mental health (B/MH) professionals varied across general and subspecialty pediatricians and whether access to, and degree of, B/MH integration in clinical settings was associated with pediatricians' perceptions of health...

Pilot Study of Cannabis Use Reduction and Associated Functional Outcomes.

AIMS: Interventions for cannabis use disorder often reduce the frequency and quantity of use, but rarely achieve sustained abstinence. It remains unclear whether reductions in use (rather than sustained abstinence) result in meaningful improvements in functioning. This study eval...

Anticoagulation Treatment Response Among Phenotypic ESUS Clusters: Evidence From CASPR

ABSTRACT Objective To evaluate treatment effect heterogeneity across phenotypic clusters of patients with cryptogenic embolic stroke using causal inference methods. Methods From a retrospective, multicenter cohort of patients with cryptogenic embolic stroke, we estimated the trea...

A phase II pilot trial of an indoleamine 2,3-dioxygenase-1 (IDO1) inhibitor (INCB024360) plus a multipeptide melanoma vaccine (MELITAC 12.1) in patients with advanced melanoma, with sequential evaluation of the tumor microenvironment

Indoleamine 2,3-dioxygenase-1 (IDO1) can mediate immune dysfunction by reducing tryptophan (Trp) and increasing kynurenine (Kyn). The CITN-04 clinical trial (NCT01961115) tested the safety and clinical activity of combination therapy with IDO1 inhibitor epacadostat (INCB024360) p...

Equivalence of DNA-based cytometry to clinical flow cytometry and CBC for immune cell quantification in peripheral blood

Clinical flow cytometry, the current standard for immune cell typing and quantification, requires intact cell membranes, complex reagents, and substantial infrastructure, making it a costly, technically demanding process. In contrast, methylation cytometry only requires the measu...

Association between index adenomas and advanced neoplasia at third surveillance colonoscopy: Data from the New Hampshire Colonoscopy Registry

Background: Due to a lack of data, the USMTSF does not provide guidance for the 3 rd surveillance exam for adenomas detected on index colonoscopy. Our aim was to assess advanced outcome risk at 3 rd surveillance in patients with index adenomas. Methods: We included patients from...

Building early career pathways in AI and medicine: a six-year pilot evaluation of the EDIT AI program

Artificial intelligence (AI) is rapidly reshaping biomedical research and clinical medicine, including cancer diagnostics, therapeutics, and healthcare delivery. Maximizing its translational impact will require a workforce capable not only of applying AI tools but also of underst...

Real-Time Symptom and Wearable Monitoring May Improve Prediction of Postoperative Recovery in Lumbar Spine Surgery Beyond Standard Measures

BACKGROUND AND OBJECTIVES: Accurately identifying candidates likely to benefit from surgery and addressing modifiable preoperative risk factors are central to optimizing outcomes. Current prediction tools often rely on static clinical data and patient-reported measures, which lac...

Stereotactic Body Radiotherapy vs Moderately Hypofractionated IMRT for Localized Intermediate-Risk Prostate Cancer

Importance The treatment of prostate cancer with radiotherapy is evolving. How quickly radiotherapy can be delivered, and the relative risks and benefits of such a treatment, is of significant public interest. Objective To determine whether stereotactic body radiotherapy (SBRT) w...
