Implementation of An Advance Care Planning Intervention in Dialysis Clinics.

Rationale & Objective: Sharing Patient's Illness Representations to Increase Trust (SPIRIT) is an evidence-based advance care planning intervention targeting dialysis patients and their surrogate decision-makers. To address SPIRIT's implementation potential, we report on a process evaluation in our recently completed five-state cluster-randomized trial.

Study Design: A descriptive study of implementation within a randomized clinical trial.

Peto's Paradox Is Dead. Long Live Peto's Paradox.

In this issue, Compton and colleagues report the prevalence of neoplasia and malignant cancer in 292 species, based on 16,049 necropsy records, shedding light on susceptibility to cancer and the evolution of mechanisms that protect against cancer across a broad array of vertebrates. See related article by Compton et al., p.

Collagen scaffold-seeded iTenocytes accelerate the healing and functional recovery of Achilles tendon defects in a rat model.

Introduction: Tendon injuries represent an ongoing challenge in clinical practice due to poor regenerative capacity, structure, and biomechanical function recovery of ruptured tendons. This study is focused on the assessment of a novel strategy to repair ruptured Achilles tendons in a Nude rat model using stem cell-seeded biomaterial.

Methods: Specifically, we have used induced pluripotent stem cell (iPSC)-derived mesenchymal stem cells (iMSCs) overexpressing the early tendon marker Scleraxis (SCX, iMSC, iTenocytes) in combination with an elastic collagen scaffold.

Identification of an Outbreak of Bivalve Transmissible Neoplasia in Soft-Shell Clams () in the Puget Sound Using Hemolymph and eDNA Surveys.

Bivalve transmissible neoplasia (BTN) is one of three known types of naturally transmissible cancer-cancers in which the whole cancer cells move from individual to individual, spreading through natural populations. BTN is a lethal leukemia-like cancer that has been observed throughout soft-shell clam () populations on the east coast of North America, with two distinct sublineages circulating at low enzootic levels in New England, USA, and Prince Edward Island, Canada. Major cancer outbreaks likely due to BTN (MarBTN) were reported in 1980s and the 2000s and the disease has been observed since the 1970s, but it has not been observed in populations of this clam species on the US west coast.

Comparison of the Effective Radiation Dose in the Region of the Facial Skull Between Multidetector CT, Dental Conebeam CT and Intraoperative 3D C-Arms.

Study Design: Experimental single-centre study of X-ray absorption using a phantom skull.

Objective: This experimental study aimed to compare the radiation doses of different 3D imaging devices used in maxillofacial surgery, including one Multidetector CT (MDCT), two Conebeam CT (CBCT) and four intraoperative 3D C-arms.

Methods: Thermoluminescent dosimeters (TLD) were used to determine the absorbed radiation in an Alderson-Rando phantom skull.
