Article Abstract
Purpose: To evaluate the outcomes of "tent form" triangular fibrocartilage complex (TFCC) repair combined with dorsal distal radioulnar joint (DRUJ) capsule imbrication for posttraumatic chronic DRUJ instability.
Methods: All patients treated with arthroscopic "tent form" TFCC repair and DRUJ capsule imbrication from 2016 to 2019 were retrospectively reviewed. The inclusion criteria were symptomatic chronic DRUJ instability for >6 months and dorsal DRUJ subluxation on magnetic resonance imaging. The Disabilities of the Arm, Shoulder, and Hand score, Patient-Rated Wrist Evaluation, grip strength, Modified Mayo Wrist Score, range of motion, and distal radioulnar joint stability were assessed for a minimum of 2 years postoperatively.
Results: Thirty-eight patients were included in the final analysis. The average follow-up duration was 35.6 months (range, 24-48 months). The 24-month postoperative grip strengths and 3-dimensional motions of wrist were not significantly different from that of the nonoperated wrist. Compared with their preoperative status, Disabilities of the Arm, Shoulder, and Hand score, Patient-Rated Wrist Evaluation, and Modified Mayo Wrist Score indicated the significant improvement with P values of .001, .001, and .002, respectively.
Conclusions: In chronic DRUJ instability with a loosening dorsal capsule, "tent form" TFCC transcapsular repair combined with DRUJ capsule imbrication restored the integrity of TFCC and dorsal DRUJ capsule and achieved a promising outcome. We recommend this procedure as an option of treatment for patients with posttraumatic chronic DRUJ instability.
Level Of Evidence: IV, case series.

"From Homelessness to Safety": Short-Term Outcomes of Low-Threshold Shelter on Individuals Experiencing Substance Use Disorder and Unsheltered Homelessness.
Subst Use Addctn J
October 2025
Boston Public Health Commission, Boston, MA, USA.
Background: To address the urgent housing needs of individuals experiencing unsheltered homelessness and substance use disorder (SUD) living in an encampment, Boston established six harm reduction low-threshold shelter (LTS) sites in January 2022.
Methods: To understand the LTS guest experience of persons who had been living in the tent encampment, assess early outcomes of the LTS service model, and inform concurrent implementation of this new shelter model, the Boston Public Health Commission implemented a point-in-time survey of 50 individuals who moved from the encampment into LTS three to six months after the encampment closure. The in-person survey assessed participant experience, quality of life, and service access.
Modular shape-changing tensegrity-blocks enable self-assembling robotic structures.

Department of Computer Science, Dartmouth College, Hanover, NH, USA.
Modular robots are currently designed to perform a variety of tasks, primarily focusing on locomotion or manipulation through the reconfiguration of rigid modules. However, the potential to integrate multiple functions, such as making each robot deployable and capable of building lattice structures for self-construction and infrastructure creation, remains largely unexplored. To advance the field, we hypothesize that combining tensegrity principles with modular robotics can create lightweight, deformable units capable of integrating three critical functions within a single design: navigating varied terrains, manipulating arbitrary shape objects, and assembling weight-sustainable, active large infrastructures.

Laboratory of Advanced Biotechnology, Beijing Institute of Biotechnology, Beijing 100071, China.
Background: Tetanus toxin, produced by , is the second deadliest known toxin. Antibodies capable of neutralizing tetanus toxin (TeNT) are vital for preventing and treating tetanus disease.
Methods: Herein, we screened thirty-six single variable domains on a heavy chain (VHHs) binding to the light chain (L) and the translocation domain (HN) (L-HN) fragment of TeNT from a phage-display library.

Adıyaman University Faculty of Nursing, Adıyaman, Türkiye.
Objectives: This study examines the relationship between post-earthquake trauma and religious coping styles among earthquake survivors with chronic diseases.
Methods: This research was conducted with 122 earthquake survivors living in tent camps in Adıyaman, affected by the earthquake between May and August 2023. Data were collected through face-to-face interviews using the "Sociodemographic Form," "Earthquake Post-Traumatic Level Determination Scale," and "Religious Coping Scale.
Compliance and Performance of Hand Hygiene in Dutch General Practice Offices Using Electronic Dispensers.

Introduction: One of the most effective measures for the reduction and prevention of healthcare-associated infections (HAI) is hand hygiene (HH). Covert direct observation of HH is difficult to realize in general practice office (GPO). The World Health Organization recognizes electronic monitoring as a form of measuring product use and estimating compliance.
