The phase 3 ZUMA-7 trial in second-line large B cell lymphoma demonstrated superiority of anti-CD19 CAR T cell therapy (axicabtagene ciloleucel (axi-cel)) over standard of care (SOC; salvage chemotherapy followed by hematopoietic transplantation) ( NCT03391466 ). Here, we present a prespecified exploratory analysis examining the association between pretreatment tumor characteristics and the efficacy of axi-cel versus SOC. B cell gene expression signature (GES) and CD19 expression associated significantly with improved event-free survival for axi-cel (P = 0.

Unlabelled: Treatment resistance and toxicities remain a risk following chimeric antigen receptor (CAR) T-cell therapy. Herein, we report pharmacokinetics, pharmacodynamics, and product and apheresis attributes associated with outcomes among patients with relapsed/refractory large B-cell lymphoma (LBCL) treated with axicabtagene ciloleucel (axi-cel) in ZUMA-7. Axi-cel peak expansion associated with clinical response and toxicity, but not response durability.

Axicabtagene ciloleucel (axi-cel) is an anti-CD19 chimeric antigen receptor (CAR) T cell therapy approved for relapsed/refractory large B cell lymphoma (LBCL) and has treatment with similar efficacy across conventional LBCL subtypes. Toward patient stratification, we assessed whether tumor immune contexture influenced clinical outcomes after axi-cel. We evaluated the tumor microenvironment (TME) of 135 pre-treatment and post-treatment tumor biopsies taken from 51 patients in the ZUMA-1 phase 2 trial.

Background: Accurate diagnosis of carpal tunnel syndrome is key to successful treatment. At our center a treatment pathway was recently established for patients with carpal tunnel syndrome. Within this pathway patients are assessed by their community practitioner.

Purpose: To describe an uncommon subset of fractured lunates in Kienböck disease that is salvageable by internal fixation.

Methods: We performed a retrospective review for patients with Kienböck disease treated by internal fixation. Demographic data, objective and radiographic measurements, patient-reported outcome measures (Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation) and pain (visual analog scale) scores were collected.

Background: Inferior scapular notching following reverse shoulder arthroplasty is due to mechanical impingement and, in some studies, has been associated with poorer functional scores, lower patient satisfaction, and more limited shoulder motion. We aimed to test the hypothesis that inferior positioning of the center of rotation with eccentric glenosphere designs decreases the adduction deficit before impingement occurs and improves clinical outcome.

Methods: A randomized, controlled, double-blinded trial was performed.

Background: The aim of this study was to compare two techniques for surgical site skin preparation in hand surgery.

Methods: We compared the standard sponge paint technique versus a plastic bag immersion technique using a 10% povidone-iodine with alcohol solution (Betadine, ORION Laboratories Pty Ltd, Balcatta,WA,Australia) to prepare surgical site skin for hand surgery. This sterile bag rubbing technique involves using a sterile plastic bag filled with 60 mL of Betadine solution to immerse the subjects' hand.

Background: Reverse total shoulder arthroplasty is a treatment option for cuff tear arthropathy. Scapular notching remains a concern. This biomechanical study compared the range-of-motion in different designs of glenospheres and hence the relative risk of scapular notching.
