Background: Germline Structural Variants (SVs) represent an important source of genetic diversity, in large part due to their influence on gene transcription. It is necessary to systematically catalog germline SVs and their associated impacted genes across different cohorts and tissue and cellular contexts, including pediatric brain or Central Nervous System (CNS) tumors.

Methods: We combined RNA with whole genome sequencing across 1430 pediatric brain or CNS tumor patients from the Children's Brain Tumor Network. We set out to systematically identify genes for which the proximity of germline SVs was recurrently and significantly associated with differential expression in the tumor sample …


Antidepressant Medication Nonadherence In Adult Patients With A Major Depressive Disorder, Sandrine Djou Kaze Aug 2025

Antidepressant Medication Nonadherence In Adult Patients With A Major Depressive Disorder, Sandrine Djou Kaze

Walden Dissertations and Doctoral Studies

The chosen approach for the Doctor of Nursing Practice (DNP) project was a clinical practice guideline (CPG) on interventions to improve antidepressant medication adherence in adults diagnosed with depression in an outpatient setting. The consequences of medication nonadherence in patients with depression are devastating for individuals and the healthcare system. Therefore, addressing it within nursing practice is essential to improve treatment efficacy and patient outcomes. The practice question related to the DNP project was to determine whether the CPG could improve antidepressant medication compliance in adults diagnosed with a depressive disorder in an outpatient setting.

Evaluating Updated Fentanyl Immunoassays For Loperamide Interference, Michael E. Walsh, Grace R. Williams, Paul J. Jannetto, K. Aaron Geno

Dartmouth Scholarship

Background

Loperamide is a µ-opioid receptor agonist that reduces intestinal peristalsis and is used to treat diarrhea. We previously described significant cross-reactivity of loperamide with 2 fentanyl immunoassays. Since then, new fentanyl immunoassays, including a CLIA-waived point-of-care device, have been approved for clinical use. Methods

We evaluated new fentanyl immunoassays for cross-reactivity to loperamide and its major metabolites, N-desmethyl loperamide (dLop) and N-didesmethyl loperamide (ddLop). Previously characterized assays were tested for cross-reactivity to ddLop, which recently became commercially available. Loperamide, dLop, and ddLop were spiked in drug-free urine for analysis by 5 enzyme immunoassays run on automated chemistry analyzers and …

Manuscripts, Articles, Book Chapters and Other Papers

Extracorporeal membrane oxygenation (ECMO) has historically been avoided in oncological patients due to perceived risks. However, recent literature suggests improved survival rates for pediatric oncology patients. Additionally, necrotizing fasciitis from Clostridium septicum is associated with high morbidity and mortality, especially in patients with preexisting malignancies. Few studies have explored the outcomes of ECMO in patients with both necrotizing fasciitis and hematologic malignancies. We present a case of a 16-year-old male with pre-B cell acute lymphoblastic leukemia (ALL) and Clostridium septicum necrotizing fasciitis successfully supported with veno-arterial (VA) ECMO. The patient underwent induction chemotherapy for ALL but developed severe septic shock …

Cerebral edema (CE) is a major component of early brain injury from aneurysmal subarachnoid hemorrhage (SAH). Despite the utility of blood-based protein markers, biomarkers targeting cerebral edema have yet to be developed. We performed a targeted proteomic search analyzing 141 proteins in plasma samples taken from 80 adult patients within 48 hours after aneurysmal rupture to identify plasma biomarkers of cerebral edema. The protein expression profiles were analyzed for associations with a higher level of the subarachnoid hemorrhage early brain edema score measured in admission computed tomography scans. Five differentially expressed proteins-brorin, ectodysplasin A2 receptor, layilin, scavenger receptor class A …

The Promise And Peril Of Comparing Fluorescence Lifetime In Biology Revealed By Simulations, Pingchuan Ma, Peter Chen, Scott Sternson, Yao Chen

2020-Current year OA Pubs

Signaling dynamics are crucial in biological systems, and biosensor-based real-time imaging has revolutionized their analysis. Fluorescence lifetime imaging microscopy (FLIM) excels over the widely used fluorescence intensity imaging by allowing the measurement of absolute signal levels independent of sensor concentration. This capability enables the comparison of signaling dynamics across different animals, body regions, and timeframes. However, FLIM's advantage can be compromised by factors like autofluorescence in biological experiments. To address this, we introduce FLiSimBA, a flexible computational framework for realistic

Dissatisfaction And Residual Symptoms In Younger And Older Adult Patients After Total Knee Arthroplasty, Nicholas Pohl, Parker Brush, Adrian Santana, Sebastian Fras, Eleanor Jenkins, Arjun Saxena

Department of Orthopaedic Surgery Faculty Papers

INTRODUCTION: Total knee arthroplasty (TKA) is an increasingly used treatment option for younger patients with osteoarthritis. Previous research has found only 66% patients < 60 years who underwent TKA postoperatively reported that their knees felt normal. However, the prior studies did not compare underlying causes for dissatisfaction based on age. This study compared the satisfaction and residual symptom rates between patients ages < 60 and ≥60 years and identified specific reasons for their dissatisfaction between the age groups.

METHODS: Patients who underwent unilateral TKA for osteoarthritis from 2014 to 2016 were electronically sent a 15-question survey pertaining to surgery satisfaction. Following patient identification and survey completion, patient demographics, medical history, surgical time, and length of stay were collected through manual review of medical records. Patients who completed surveys were grouped by age (< 60 years or ≥60 years) for analysis.

RESULTS: In total, 1189 ≥ 60-year-old patients and 388 < 60-year-old patients were included. Most patients in both cohorts reported satisfaction with overall knee function (< 60: 68.6%; ≥60: 71.8%; P = 0.175). Fewer < 60-year patients reported normal knee function (66.5% vs. 75.2%; P < 0.001). The most common residual symptom in both cohorts was continued pain.

CONCLUSION: Patients younger than 60 years reported less satisfaction with performing normal activities …

Is Health Insurance Related To Breastfeeding Duration?, Anna De La Paz

Population Health Research Brief Series

Breastfeeding duration, which plays an important role in shaping maternal and infant health, can be influenced by insurance type. This data slice uses data from the 2022-2023 National Survey of Family Growth (NSFG) to described differences in breastfeeding duration by insurance type among females ages 15-49 in the United States. Findings show that mothers with private insurance breastfeed longer than mothers with public insurance, such as Medicaid, net of controls for maternal age, race, education, and income.
