Comparison of a Novel Posterior Integrated Transfixation Sacroiliac Joint Fusion Approach to the Posterolateral and Lateral Approaches: A Cadaveric Biomechanical and Computational Analysis of the Fixation, Invasiveness, and Fusion Area.

Purpose: To concurrently assess and compare the fixation efficacy, invasiveness, and fusion potential of a posterior integrated transfixation cage system to the posterolateral threaded implant and lateral triangular rod systems, in a cadaveric model.

Methods And Materials: Twelve (12) cadaveric sacroiliac joint specimens were utilized and tested within the single-leg stance multidirectional pure moment bending model. Each specimen was tested in the intact, destabilized, treated (using posterior, posterolateral, and lateral systems), and post-fatigue conditions by applying 0 to ± 7.

Cervical Cancer Screening: Patient Perspectives on Transitioning to Primary High-Risk Human Papillomavirus Testing Alone.

Introduction: In 2018, the US Preventive Services Task Force updated cervical cancer screening recommendations to allow for screening every 5 years with primary human papillomavirus (HPV) testing in combination with cytology (cotesting) or every 5 years with primary HPV screening alone. Despite these changes, the uptake of primary HPV screening has been lower than expected. The purpose of this study was to evaluate the patient perspective of an integrated health system transition from cotesting to primary HPV testing among a 30- to 65-year-old cohort.

Terminal differentiation precedes functional circuit integration in the peduncle neurons in regenerating Hydra vulgaris.

Understanding how neural circuits are regenerated following injury is a fundamental question in neuroscience. Hydra is a powerful model for studying this process because it has a simple neural circuit structure, significant and reproducible regenerative abilities, and established methods for creating transgenics with cell-type-specific expression. While Hydra is a long-standing model for regeneration and development, little is known about how neural activity and behavior is restored following significant injury.
