Ultrasound imaging is widely valued for its safety, non-invasiveness, and real-time capabilities but is often limited by operator variability, affecting image quality and reproducibility. Robot-assisted ultrasound may provide a solution by delivering more consistent, precise, and faster scans, potentially reducing human error and healthcare costs. Effective force control is crucial in robotic ultrasound scanning to ensure consistent image quality and patient safety.

This paper presents, for the first time, a rotary actuator functionalized by an inclined disc rotor that serves as a distal optical scanner for endoscopic probes, enabling side-viewing endoscopy in luminal organs using different imaging/analytic modalities such as optical coherence tomography and Raman spectroscopy. This scanner uses a magnetic rotor designed to have a mirror surface on its backside, being electromagnetically driven to roll around the cone-shaped hollow base to create a motion just like a precessing coin. An optical probing beam directed from the probe's optic fiber is passed through the hollow cone to be incident and bent on the back mirror of the rotating inclined rotor, circulating the probing beam around the scanner for full 360° sideway imaging.

The human immunodeficiency virus (HIV) pandemic is a global public health and social justice issue. HIV continues to disproportionately affect marginalized populations, including immigrants and refugees living with HIV (IRLHIV). This study investigated and captured the experiences of IRLHIV using the social determinants of health framework.

Native Hawaiians (NHs) are a historically oppressed population disproportionately burdened by diabetes and related complications. The Kilolani Project, a patient navigator-centered, chronic disease management program, targets upstream drivers of health among vulnerable NH adult patients with diabetes within an urban academic safety-net clinic. To investigate the impact of the Kilolani Project, we performed a qualitative study to examine patient perspectives.

Objective: To investigate the efficacy and safety of drug-eluting beads transcatheter arterial chemoembolization(DEB-TACE) combined with systemic chemotherapy and immune checkpoint inhibitors in the treatment of unresectable intrahepatic cholangiocarcinoma.
Methods: This study used retrospective cohort analysis to collect the clinical data of 209 patients with unresectable intrahepatic cholangiocarcinoma treated in Linyi Cancer Hospital, Affiliated Zhongshan Hospital of Dalian University, Affiliated Central Hospital of Dalian University of Technology from January 2020 to January 2024. The patients were divided into observation group and control group based on their treatment plans.
