Psychometric Properties of the Generalized Anxiety Disorder Scale (GAD-7) in Older Adults With Advanced Cancer.

Objectives: Over half of new cancer diagnoses occur in patients aged 65 or older, with up to 40% experiencing anxiety. The American Society of Clinical Oncology recommends using the Generalized Anxiety Disorder Scale (GAD-7) for anxiety screening, but the GAD-7 psychometric properties in this population are unknown. This study examined the GAD-7's reliability, validity, and item parameters, comparing its utility with the GAD-2 in older adults with cancer.

Interdisciplinary provider visits attenuate relationship between patient concerns and distress in older adults with cancer.

Purpose: This study examined the relationship between multidimensional patient concerns and anxiety and depression in a national sample of older adults with cancer (OACs ≥ 65 years) and the buffering effect of visiting providers across disciplines (e.g., oncology, allied health, primary care, mental health) on these relationships.

Conductive gradient hydrogels allow spatial control of adult stem cell fate.

Electrical gradients are fundamental to physiological processes including cell migration, tissue formation, organ development, and response to injury and regeneration. Current electrical modulation of cells is primarily studied under a uniform electrical field. Here we demonstrate the fabrication of conductive gradient hydrogels (CGGs) that display mechanical properties and varying local electrical gradients mimicking physiological conditions.

Wirelessly Powered-Electrically Conductive Polymer System for Stem Cell Enhanced Stroke Recovery.

Effective stroke recovery therapeutics remain limited. Stem cell therapies have yielded promising results, but the harsh ischemic environment of the post-stroke brain reduces their therapeutic potential. Previously, we developed a conductive polymer scaffold system that enabled stem cell delivery with simultaneous electrical modulation of the cells and surrounding neural environment.

Telehealth-Based Music Therapy Versus Cognitive Behavioral Therapy for Anxiety in Cancer Survivors: Rationale and Protocol for a Comparative Effectiveness Trial.

Background: Cancer survivors represent one of the fastest growing populations in the United States. Unfortunately, nearly 1 in 3 survivors experience anxiety symptoms as a long-term consequence of cancer and its treatment. Characterized by restlessness, muscle tension, and worry, anxiety worsens the quality of life; impairs daily functioning; and is associated with poor sleep, depressed mood, and fatigue.

Electrical modulation of transplanted stem cells improves functional recovery in a rodent model of stroke.

Stroke is a leading cause of long-term disability worldwide, intensifying the need for effective recovery therapies. Stem cells are a promising stroke therapeutic, but creating ideal conditions for treatment is essential. Here we developed a conductive polymer system for stem cell delivery and electrical modulation in animals.

Electrical stimulation of human neural stem cells via conductive polymer nerve guides enhances peripheral nerve recovery.

Severe peripheral nerve injuries often result in permanent loss of function of the affected limb. Current treatments are limited by their efficacy in supporting nerve regeneration and behavioral recovery. Here we demonstrate that electrical stimulation through conductive nerve guides (CNGs) enhances the efficacy of human neural progenitor cells (hNPCs) in treating a sciatic nerve transection in rats.

Conducting polymer-based granular hydrogels for injectable 3D cell scaffolds.

Injectable 3D cell scaffolds possessing both electrical conductivity and native tissue-level softness would provide a platform to leverage electric fields to manipulate stem cell behavior. Granular hydrogels, which combine jamming-induced elasticity with repeatable injectability, are versatile materials to easily encapsulate cells to form injectable 3D niches. In this work, we demonstrate that electrically conductive granular hydrogels can be fabricated via a simple method involving fragmentation of a bulk hydrogel made from the conducting polymer PEDOT:PSS.

Functional analysis and generalized treatment of disruptive behavior during dental exams.

Patient disruption during dental visits can impede treatment and may result in invasive approaches to care. The current study evaluated the efficacy of graduated exposure with and without extinction to decrease disruption during dental treatment for 4 young men with autism spectrum disorder (ASD). Modified functional analyses confirmed that disruption was maintained by escape from dental demands for all four young men.

Single-Cell Encapsulation via Click-Chemistry Alters Production of Paracrine Factors from Neural Progenitor Cells.

Extracellular matrix (ECM) properties affect multiple cellular processes such as cell survival, proliferation, and protein synthesis. Thus, a polymeric-cell delivery system with the ability to manipulate the extracellular environment can act as a fundamental regulator of cell function. Given the promise of stem cell therapeutics, a method to uniformly enhance stem cell function, in particular trophic factor release, can prove transformative in improving efficacy and increasing feasibility by reducing the total number of cells required.

Morphing electronics enable neuromodulation in growing tissue.

Bioelectronics for modulating the nervous system have shown promise in treating neurological diseases. However, their fixed dimensions cannot accommodate rapid tissue growth and may impair development. For infants, children and adolescents, once implanted devices are outgrown, additional surgeries are often needed for device replacement, leading to repeated interventions and complications.

Age-Related Outcomes in Total Ankle Arthroplasty: An Analysis of 112 Patients.

Traditionally, total ankle replacement has been reserved for elderly patients with low physical demands. With nearly 80% of end-stage ankle arthritis being secondary to prior trauma, patients may require a replacement at a much younger rate than primary hip and knee arthritis. Historical accounts of implant failure and high revision rates in younger patients have been reported in the literature.

Teaching Helping Babies Breathe via Telehealth: A New Application in Rural Guatemala.

Background: Helping Babies Breathe (HBB) is a neonatal resuscitation curriculum that teaches life-saving interventions utilized in the first minutes after birth, reducing morbidity and mortality. Traditionally, it requires in-person facilitators for didactic and hands-on training.

Objectives: The aim of this study was to offer HBB to nurses and nursing students in Guatemala, with the lead facilitator presenting concepts via telehealth and in-person facilitators providing hands-on demonstration.

Controlling properties of human neural progenitor cells using 2D and 3D conductive polymer scaffolds.

Human induced pluripotent stem cell-derived neural progenitor cells (hNPCs) are a promising cell source for stem cell transplantation to treat neurological diseases such as stroke and peripheral nerve injuries. However, there have been limited studies investigating how the dimensionality of the physical and electrical microenvironment affects hNPC function. In this study, we report the fabrication of two- and three-dimensional (2D and 3D respectively) constructs composed of a conductive polymer to compare the effect of electrical stimulation of hydrogel-immobilized hNPCs.

Effects of decreasing intersession interval duration on graduated exposure treatment during simulated routine dental care.

Reports suggest that individuals with developmental disabilities often engage in behavior during dental visits that precludes regular dental care. Graduated exposure therapies are an effective treatment for avoidant behavior in people with developmental delays, and some studies show that the duration of the intersession interval (ISI) can impact the effectiveness of graduated exposure treatments for typically developing individuals. The current study examined the effects of decreasing ISI on outcomes of a graduated exposure treatment during simulated routine dental care for 3 individuals diagnosed with autism.

Intraoperative Reduction Techniques for Surgical Management of Displaced Intra-Articular Calcaneal Fractures.

Fractures of the calcaneus are detrimental injuries, often caused by high-energy trauma. To best restore the functionality of a limb and allow normal ambulation, it is recommended to repair displaced intra-articular calcaneus fractures surgically. This article presents several methods of reduction and repair of the calcaneus.

Attitudes Toward Communication and Collaboration After Participation in a Mock Page Program: A Pilot of an Interprofessional Approach to Surgical Residency Preparation.

Objective: A source of insecurity among new physicians and new nurses is communicating and managing acute changes in patient condition. Mock page programs are an effective method for teaching communication and clinical decision-making skills to medical students. Joint participation in a mock page program provides a unique opportunity for medical and nursing students to practice communication, collaboration, and clinical decision-making in a low-risk learning environment.

Sleep patterns predictive of daytime challenging behavior in individuals with low-functioning autism.

Unlabelled: Increased severity of problematic daytime behavior has been associated with poorer sleep quality in individuals with autism spectrum disorder. In this work, we investigate whether this relationship holds in a real-time setting, such that an individual's prior sleep can be used to predict their subsequent daytime behavior. We analyzed an extensive real-world dataset containing over 20,000 nightly sleep observations matched to subsequent challenging daytime behaviors (aggression, self-injury, tantrums, property destruction and a challenging behavior index) across 67 individuals with low-functioning autism living in two U.
