Implementation Of Safety Restraint Chair Algorithm With De-Escalation Techniques To Decrease Restraint Time In Acute Psychiatric Unit, Chiamaka Nwadike

Doctor of Nursing Practice Final Project Abstract

Purpose: This quality improvement project aims to (1) decrease time in restraint use on the inpatient psychiatric unit through implementing the restraint chair protocol, and (2) improve staff satisfaction in using safety restraint.

Background: In acute psychiatric care, restraints are used to ensure safety, but they pose physical and psychological risks. There is an increasing recognition of the need for patient safety, including the use of de-escalation techniques that prioritize restraint chairs over bed restraints to ensure safety.

Methodology: The project follows the Plan-Do-Study-Act (PDSA) model, which supports a continuous improvement approach to implementing the restraint chair …

Defining Three Principles For Credible Evidence Synthesis And Reviews In Health Professions Education, Michelle Daniel, Morris Gordon, Hussein Uraiby, Peter Boedeker, Janice Hanson, Diana Dolmans, Satid Thammasitboon

Faculty, Staff and Students Publications

As reviews become increasingly central to informing educational practice and guiding research in health professions education, the need for methodological clarity and quality has grown. This Commentary highlights three foundational principles - alignment, rigor, and transparency - that underpin high-quality reviews, regardless of type. We illustrate how these principles apply across commonly used review types, including systematic, scoping, realist, and narrative reviews. By aligning the research question with the appropriate review methodology, employing rigorous processes for evidence collection and synthesis, and maintaining transparency in methodological reporting, review teams can produce credible, transferable, and dependable findings. Embracing these principles not only …

Human vision relies on retinal ganglion cells (RGCs), and their connectivity with distinct brain regions enables higher order visual processing. RGCs vary considerably between species, and small model organisms display distinct RGC innervation patterns from that in humans. There is thus a need for robust models of human RGC circuit formation that preserves innervation specificity. Here, we developed an in vitro microfluidics eye-to-brain connectivity model using human pluripotent stem cell (hPSC)-derived RGCs to assess brain region-specific connectivity features. We find that cultured human RGCs segregate their dendrites and axons and display axonal features that align with that of their in …

Cognitive Interviews With Emergency Physicians To Understand Disposition Decisions With People With Dementia With Borderline Cases, Anita N Chary, Annika R Bhananker, Rebecca Franks, Adrian Haimovich, Aanand D Naik, Maura Kennedy, Kei Ouchi

Faculty, Staff and Students Publications

People with dementia are often hospitalized from the emergency department (ED) for "borderline cases," where outpatient or inpatient management may be clinically reasonable. We sought to investigate how ED physicians make and communicate about decisions in borderline cases. Through cognitive interviews, we asked attending ED physicians from an academic hospital to share their approach to scenarios representing borderline cases with people with dementia and verbalize communication about ED disposition with patients and care partners. We deductively coded responses related to patient/care partner engagement and key features of communication and then elucidated themes related to content and phrasing of communication. Of …

Characterizing Spatial Epidemiology In A Heterogeneous Transmission Landscape Using The Spatial Transmission Count Statistic, Leke Lyu, Gabriella Veytsel, Guppy Stott, Spencer Fox, Cody Dailey, Lambodhar Damodaran, Kayo Fujimoto, Pamela Brown, Roger Sealy, Armand Brown, Magdy Alabady, Justin Bahl

Faculty, Staff and Student Publications

Background: Viral genomes contain records of geographic movements and cross-scale transmission dynamics. However, the impact of regional heterogeneity, particularly among rural and urban centers, on viral spread and epidemic trajectory has been less explored due to limited data availability. Intensive and widespread efforts to collect and sequence SARS-CoV-2 viral samples have enabled the development of comparative genomic approaches to reconstruct spatial transmission history and understand viral transmission across different scales.

Methods: We proposed the spatial transmission count statistic that efficiently summarizes the geographic transmission patterns imprinted in viral phylogenies. Guided by a time-scaled tree with ancestral trait states, we identified …

Ligand-Activated Egfr/Mapk Signaling But Not Pi3k, Are Key Resistance Mechanisms To Egfr-Therapy In Colorectal Cancer, Xueping Qu, Habib Hamidi, Radia M Johnson, Ethan S Sokol, Eva Lin, Cathy Eng, Tae Won Kim, Johanna Bendell, Smruthy Sivakumar, Benjamin Kaplan, Felipe De Sousa E Melo, Andrew Mancini, Matthew Wongchenko, Yi Shi, David Shames, Yibing Yan, Fortunato Ciardiello, Carlos Bais

Understanding mechanisms of resistance to active therapies is crucial for developing more effective treatments. Here, we investigate resistance to anti-EGFR and anti-VEGF plus chemotherapy treatment in colorectal cancer (CRC) patients from the IMblaze370 trial (NCT02788279). While anti-VEGF does not select for secondary mutations, anti-EGFR leads to simultaneous mutations in EGFR and MAPK, but not PI3K pathway genes. Notably, we observe frequent acquired mutations in the EGFR extracellular but not intracellular domain and that patients with higher baseline expression of EGFR-ligands are prone to acquire resistant mutations. This data reveals a ligand-activated EGFR/MAPK-signaling dependency in CRC. We also observe enrichment for …

Intracellular Inclusions Induced By Patient-Derived And Amplified Α-Synuclein Aggregates Are Morphologically Indistinguishable, Rabab Al-Lahham, Mark E Corkins, Mohd Ishtikhar, Prakruti Rabadia, Santiago Ramirez, Victor Banerjee, Mohammad Shahnawaz

Faculty, Staff and Student Publications

Lewy Body Disease (LBD) and Multiple System Atrophy (MSA) are synucleinopathies with distinct prognoses and neuropathologies, however, with overlapping clinical symptoms. Different disease characteristics are proposed to be determined by distinct conformations of alpha-synuclein (α-Syn) aggregates, which can self-propagate and spread between cells via a prion-like mechanism. The goal of this study is to investigate whether α-syn aggregates amplified from brain and CSF samples of LBD and MSA patients using the Seed Amplification Assay (SAA) maintain α-Syn seeding properties similar to those of α-syn aggregates derived from patients' brains. To address this, SAA-amplified and un-amplified α-Syn aggregates from LBD and …

50 Years Of Child And Adolescent Suicide Prevention Interventions: A Review Of Randomized Controlled Trials And Their Moderators And Mediators, Pauline Goger, Rachel Nam, Nathan Lowry, Christine B. Cha, Jessica Ribeiro, Xieyining Huang, Kathryn R. Fox

Journal of Applied Research on Children: Informing Policy for Children at Risk

Suicidal thoughts and behaviors (STBs) in youth are prevalent and impairing, but available psychosocial treatments are difficult to access and show limited efficacy. Prevention strategies are interventions intended to be implemented during relative well-periods before impairment or other adverse outcomes set in and therefore help avoid undue distress or psychological sequelae. However, prevention strategies have not always been clearly distinguished from treatment strategies in prior reviews. Additionally, increasing prevention efficacy by identifying what works how and for whom to allow for personalization of interventions could be impactful, but has not been sufficiently probed. To help address these knowledge gaps, a …

Hammond, Stephanie Luther, Geovanna Rodriguez, James Sinclair, Rhonda N.T. Nese, Marielena R. Mcwhirter Boisen, Skylar Steffes, James R. Muruthi, John R. Seeley

Journal of Applied Research on Children: Informing Policy for Children at Risk

Extant literature has established an elevated risk for suicidal thoughts and behaviors (STB) among lesbian, gay, bisexual, transgender, and/or queer (LGBTQ) youth when compared to their non-LGBTQ peers. Not yet studied is the impact of institutional betrayal on STB among LGBTQ youth. Institutional betrayals refers to misconduct carried out by an institution upon individuals reliant on the institution. Using retrospective data from 229 LGBTQ adults, we examined: (a) whether institutional betrayal was associated with STB among LGBTQ individuals in grades 5 through 12, (b) whether the association between institutional betrayal and STB was significant after controlling for the covariates, and …

The therapeutic landscape in ALL has changed dramatically over the last decade. Allogeneic blood or marrow transplantation (AlloBMT) has also evolved and remains an important option for consolidation. We assessed the interplay between these factors by analyzing the outcomes of 251 adult ALL (214 B and 37 T ALL) patients undergoing alloBMT with post-transplantation cyclophosphamide (PTCy) across two eras: 2008-2014 (ERA1) and 2015-2022 (ERA2). ERA1 patients were younger (median age 45.5 vs. 50, p=0.03), less likely to have an HCT-CI ≥4 (9% vs. 21%, p=0.01), more likely to have MRD by flow cytometry (20% vs. 9%, p=0.01) and receive myeloablative …

Increased Fatty Acid Delivery By Tumor Endothelium Promotes Metastatic Outgrowth, Deanna N Edwards, Shan Wang, Kelby Kane, Wenqiang Song, Laura C Kim, Verra M Ngwa, Yoonha Hwang, Kevin Ess, Mark R Boothby, Jin Chen

Faculty, Staff and Students Publications

Metastatic outgrowth in distant microscopic niches requires sufficient nutrients, including fatty acids (FAs), to support tumor growth and to generate an immunosuppressive tumor microenvironment (TME). However, despite the important role of FAs in metastasis, the regulation of FA supply in metastatic niches has not been defined. In this report, we show that tumor endothelium actively promotes outgrowth and restricts antitumor cytolysis by transferring FAs into developing metastatic tumors. We describe a process of transendothelial FA delivery via endosomes that requires mTORC1 activity. Thus, endothelial cell-specific targeted deletion of Raptor (RptorECKO), a unique component of the mTORC1 complex, significantly reduced metastatic …

BACKGROUND: Social network data are essential and informative for public health research and implementation as they provide details on individuals and their social context. For example, health information and behaviors, such as HIV-related prevention and care, may disseminate within a network or across society. By harmonizing egocentric and digital networks, researchers may construct a sociocentric-like "fuzzy" network based on a subgroup of the population.

OBJECTIVE: We aimed to generate a more complete sociocentric-like "fuzzy" network by harmonizing alternative sources of egocentric and digital network data to examine relationships between participants in the Neighborhoods and Networks (N2) cohort study. Further, we …

Cancer genomic studies have identified frequent mutations in subunits of the SWI/SNF chromatin remodeling complex, including SMARCA4 in nonsmall cell lung cancer with a frequency of up to 33% in advanced-stage disease, making it the most frequently mutated complex. We and others have identified SMARCA2 to be synthetic lethal to SMARCA4, indicating that SMARCA2 is a high-value therapeutic target. Here, we disclose the discovery and characterization of potent, selective, and orally bioavailable cereblon-based SMARCA2 PROTACs. Biochemically, we showed that YDR1 and YD54 are potent SMARCA2 degraders. Further, we showed the antitumor growth inhibitory activity of YDR1 and YD54 in SMARCA4 …

There is a need for novel therapies for patients with previously treated HER2-positive gastroesophageal adenocarcinoma (GEA). This phase 1 (NCT02892123) dose-escalation and expansion trial evaluated zanidatamab (a dual HER2-targeted bispecific antibody) ± chemotherapy in previously treated patients with HER2-expressing, locally advanced/metastatic cancers. Here, we report the outcomes for GEA cohorts receiving zanidatamab monotherapy or with chemotherapy (paclitaxel or capecitabine). The primary endpoint was safety and tolerability. Secondary endpoints were objective response rate (ORR), disease control rate, progression-free survival, pharmacokinetics, and immunogenicity. Seventy patients were enrolled (n = 29 monotherapy; n = 41 combination therapy); most received prior HER2-targeted agents (monotherapy, …

Empathy And Psychological Outcomes In Informal Caregivers Of Community-Dwelling Older Adults: A Systematic Review And Meta-Analysis, Meng Huo, Thi Vu, Tomiko Yoneda, Jingkai Wei, Bruce Abbott, Joan K Monin

Faculty, Staff and Student Publications

Objectives: Scholars have increasingly recognized the crucial role that empathy plays as informal caregivers provide unpaid care to their older family and friends (i.e., care recipients). Yet, the existing literature exhibits substantial variability in study approaches and results, which limits the extent to which this literature can inform interventions intended to benefit informal caregivers. We sought to address this critical gap by synthesizing research that examined how caregivers' and care recipients' empathy were associated with caregivers' psychological health.

Methods: We conducted a literature search using PubMed, PsycInfo, CINAHL (Cumulative Index to Nursing and Allied Health Literature), EMBASE, and Scopus databases …

Research on the relationship between resistin levels, metabolic health, and obesity has produced inconsistent findings across different ethnic groups, making it unclear whether lower resistin levels are associated with these conditions in Mexican-Americans. This cross-sectional study investigated the relationship between resistin, metabolic health, and obesity in an adult Mexican-American cohort (n = 1511) using multivariable linear regression analysis. Related adipokines (leptin and adiponectin) were measured simultaneously. Participants were categorized into four groups by metabolic health (healthy/unhealthy) and obesity (obese/non-obese) status. “Metabolically unhealthy” was defined as ≥2 cardiometabolic abnormalities. Obesity was defined as a BMI ≥ 30 kg/m2. We also …

Soil-transmitted helminth (STH) infections rank among the most prevalent communicable diseases of humans, yet detection of these parasites is mostly restricted to identifying active infection through fecal examinations. Currently, there are no commercial diagnostic tools to identify a prior whipworm or hookworm exposure, and the few serological assays for roundworm infection have not been well validated for crossreactivity or infections in humans. Such diagnostic restrictions limit the range of scientific and clinical questions that surround STH exposures and their implicated relationship to chronic diseases, such as autoimmunity, allergy, and cancer. The goal of this investigation was to evaluate the diagnostic …

Age-related white matter (WM) microstructure maturation and decline occur throughout the human lifespan, complementing the process of gray matter development and degeneration. Here, we create normative lifespan reference curves for global and regional WM microstructure by harmonizing diffusion MRI (dMRI)-derived data from ten public datasets (N = 40,898 subjects; age: 3-95 years; 47.6% male). We tested three harmonization methods on regional diffusion tensor imaging (DTI) based fractional anisotropy (FA), a metric of WM microstructure, extracted using the ENIGMA-DTI pipeline. ComBat-GAM harmonization provided multi-study trajectories most consistent with known WM maturation peaks. Lifespan FA reference curves were validated with test-retest data …

Simplified Control Of Neuromuscular Stimulation Systems For Restoration Of Reach With Limb Stiffness As A Modifiable Degree Of Freedom, Tyler R Johnson, Chase A Haddix, A Bolu Ajiboye, Dawn M Taylor

Faculty, Staff and Student Publications

Objective. Brain-controlled functional electrical stimulation (FES) of the upper limb has been used to restore arm function to paralyzed individuals in the lab. Able-bodied individuals naturally modulate limb stiffness throughout movements and in anticipation of perturbations. Our goal is to develop, via simulation, a framework for incorporating stiffness modulation into the currently-used ‘lookup-table-based’ FES control systems while addressing several practical issues: (1) optimizing stimulation across muscles with overlap in function, (2) coordinating stimulation across joints, and (3) minimizing errors due to fatigue. Our calibration process also needs to account for when current spread causes additional muscles to become activated. Approach. …
