Secondhand smoke exposure can significantly worsen asthma outcomes in pediatric patients, leading to increased exacerbations and healthcare utilization. Caregivers can play a critical role in reducing secondhand smoke exposure, however sustained smoking cessation can be challenging to achieve. Two powerful healthcare interventions to assist in caregiver smoking cessation include motivational interviewing and educational handouts, however their compared effectiveness has not yet been fully reviewed. This scoping review compared the effectiveness of motivational interviewing and educational handouts in promoting smoking cessation among caregivers of children hospitalized for asthma exacerbations over the course of 90 days.

Purpose/Background

Patients with diabetes mellitus are significantly more prone to delayed gastric emptying, which can increase their risk for aspiration events in the operating room despite following standard fasting guidelines set by the American Society of Anesthesiologists (ASA). Using point-of-care gastric ultrasound, trained providers can quickly and accurately evaluate gastric volumes and risk-stratify patients based on these findings. However, these methods have not been clearly assessed in the diabetic population. The purpose of this scoping review is to map the existing evidence on the use of gastric ultrasound findings among adult patients with diabetes undergoing anesthesia.

Purpose/Background 

Spinal anesthesia is widely used in surgical practice because it provides effective anesthesia and analgesia while reducing the need for intravenous anesthesia. Opioids are commonly used as intrathecal adjuvants; however, their use is associated with adverse effects such as pruritus, postoperative nausea and vomiting (PONV), urinary retention, and respiratory depression. Dexmedetomidine, a selective α2-adrenergic agonist, has gained attention as an alternative to opioids due to its sedative and analgesic properties without the opioid side effect profile. This scoping review evaluates current evidence comparing intrathecal Dexmedetomidine and opioids as adjuvants to spinal anesthesia in adult surgical patients.

Quantitative Fluorescence Imaging Using A Paired Agent Approach For Improving Surgical Decision Making, Sanjana Pannem 2026 Dartmouth College

Quantitative Fluorescence Imaging Using A Paired Agent Approach For Improving Surgical Decision Making, Sanjana Pannem

Dartmouth College Ph.D Dissertations

Surgical resection remains to be the cornerstone of treatment for most solid tumors, where the primary objective is to remove all visible and microscopic disease. However, the extent of tumor resection is inherently limited by the surgeon’s ability to distinguish tumor from normal tissue, intraoperatively. As a result, positive surgical margins (PSM), where residual tumor remains after surgery, are a common occurrence and are associated with increased recurrence, need for adjuvant therapies, dismal patient outcomes, and high healthcare costs.

Fluorescence guided surgery (FGS) has emerged as a promising technique to enhance intraoperative visualization of tumors and may help reduce the …

Doctor of Nursing Practice Projects

Purpose/Background

Individuals with Type II diabetes mellitus (T2DM) experience increased risk of cardiovascular disease and higher mortality rates relative to non-diabetic populations. Continuous glucose monitoring (CGM) enables more precise analysis of glucose patterns and trends compared to conventional self-monitoring of blood glucose (SMBG). CGM provides frequent measurements and generate meaningful metrics, such as time in range (TIR), time above range (TAR), and time below range (TBR), allowing evaluation of glucose stability and variability. Despite these advantages, evidence comparing CGM and SMBG remains inconsistent. This scoping review aims to evaluate how CGM compares with SMBG across reported outcomes, including TIR, TAR, …

Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

The continued evolution of SARS-CoV-2 has enabled an escape from most monoclonal antibodies, yet a subset of broadly neutralizing antibodies targeting three newly identified super-conserved RBD epitopes—SCORE-A, SCORE-B, and SCORE-C—retains remarkable activity against even the most recent JN.1-derived sublineages. Here, we employed an integrated computational framework combining conformational dynamics, mutational scanning, MM-GBSA binding energetics, and frustration profiling to dissect the molecular mechanisms by which XGI antibodies achieve broad neutralization and resistance to immune escape. Structural analysis revealed that all three SCORE epitopes share a common architecture: a highly conserved, minimally frustrated core that provides stable anchoring, flanked by peripheral regions …

Purpose/Background 

Colorectal cancer (CRC) remains a significant public health concern in the United States, with screening rates below national targets due to persistent socioeconomic and structural barriers, particularly among underserved populations. Stool-based screening modalities offer accessible alternatives to colonoscopy, and emerging evidence suggests that home-based delivery models may improve screening uptake; however, implementation strategies vary and comparisons between home-based and clinic-based approaches remain limited. This scoping review examines current evidence on strategies that support CRC screening uptake, with a focus on stool-based modalities, including fecal immunochemical testing (FIT), fecal occult blood testing (FOBT), and multitarget stool DNA testing (mDNA), and …

Doctor of Nursing Practice Projects

Background

Psychosis in adults is a serious psychiatric condition that often necessitates inpatient hospitalization for stabilization and the initiation of medication. Untreated psychosis can lead to poor outcomes, including longer hospital stays, loss of occupational functioning, and a decreased quality of life. While antipsychotic medications are typically the first line of treatment, they can have severe side effects, which may lead to patients discontinuing their use. Cognitive Behavioral Therapy (CBT) for psychosis is an evidence-based intervention that targets maladaptive behaviors associated with the condition. CBT may improve treatment responses when used alongside antipsychotic medication. However, there is limited research on …

Tanzania Journal of Science

This study utilized Monte Carlo (MC) simulations to optimize radiation doses in pediatric multidetector computed tomography (MDCT) head scans by analyzing key parameters like tube current (mA), tube voltage (kV), pitch, and slice thickness. The findings indicate that reducing tube current significantly lowers the Computed Tomography Dose Index (CTDIvol) and Dose Length Product (DLP), effectively minimizing patient radiation exposure. Higher pitch values (0.7–0.9) further reduced radiation by decreasing beam overlap, while using a thinner slice thickness (0.6 mm) improved dose efficiency. A comparison highlighted the effectiveness of optimization: simulated parameters kVp 100, mAs 81, pitch 0.98 yielded a CTDIvol of …

Mapping The Evidence On The Maternal–Fetal Triage Index (Mfti): A Scoping Review, Taylor Harris, Kelsey Downie, Margaret Harvey Phd, Aprn, Acnp-Bc, Chfn, Fhrs

Doctor of Nursing Practice Projects

Purpose/Background

Maternal morbidity and mortality remain persistent challenges in the United States, with obstetric triage serving as a critical point of entry for timely recognition and management of high-acuity maternal-fetal conditions. Despite recommendations for acuity-based triage models, many obstetric units continue to rely on non-specific emergency triage tools, such as the Emergency Severity Index (ESI), which inadequately account for pregnancy-specific physiological changes and fetal status. To address these limitations, the Association of Women’s Health, Obstetric and Neonatal Nurses developed the Maternal-Fetal Triage Index (MFTI), a five-level obstetric-specific triage tool. Although the MFTI has been increasingly adopted in clinical practice, the …


Optimizing Itpa R178c Assays Via Hplc, Jared J. Reisnouer, Wally D. Pines 2026 Eastern Washington University

Optimizing Itpa R178c Assays Via Hplc, Jared J. Reisnouer, Wally D. Pines

2026 Symposium

Two of the major nucleotide bases in DNA and RNA (Adenine and Guanine) are derived from the purine Inosine Monophosphate (IMP). IMP may occasionally form the noncanonical nucleotide Inosine Triphosphate (ITP) within the cell and become incorporated into DNA during replication, leading to potentially lethal errors. To combat this, human cells produce the “housekeeping” enzyme Inosine Triphosphatase (ITPA) to revert ITP to IMP. A mutation of this protein that replaces the 178th amino acid Arginine with Cysteine (R178C) is associated with a fatal infantile encephalopathy. Previous assessments of enzyme-substrate binding and catalysis for ITPA variants have been run at a …

Pharmacy Faculty Articles and Research

Purpose

Postsurgical adhesion remains a significant clinical challenge. Seprafilm® is widely used as a barrier to reduce adhesion formation, however its efficacy may be inconsistent. Recombinant human proteoglycan-4 (rhPRG4), a surface-active, anti-inflammatory glycoprotein found in synovial fluid inhibits cell and protein adhesion. This study investigated whether coating Seprafilm with rhPRG4 could enhance its anti-adhesive potential.

Methods

Macrophages (J774), human fibroblast-like synoviocytes (HFLS), and melanoma (A375) cells were cultured on tissue culture wells treated with rhPRG4 or bovine submaxillary mucin (BSM) to determine optimal seeding density. Seprafilm sheets were coated with rhPRG4 or BSM (0.78–200 µg/mL). Cell adhesion was quantified …
