Nurse Efficiency & Ultrasound Guided Intravenous Access: Evidence Based Intervention Benchmark, Jacob D. Frost

MSN Capstone Projects

Gaining IV access is this first step into accurate, timely diagnosis and interventions of patients. Nurses are typically the first medical professional a patient sees. If the nurse can establish IV access as early as possible this will lead to faster interventions faster diagnostic results and better management for patients and ultimately better patient outcomes. Ultrasound guided IV can increase first attempt success rates leading to decreased painful IV insertions by multiple nurses. This would increase patient satisfactions scores leading to higher re-imbursement.

Detection of extrathyroidal extension (ETE) in patients with papillary thyroid carcinoma (PTC) influences treatment plan and surgical aggressiveness. Ultrasound (US) is the long-standing preoperative imaging method of choice. Recent literature from Asia suggests US accuracy to be influenced by patient characteristics, such as body mass index (BMI). Here, we examine the effect of BMI on the accuracy of US at a North American tertiary referral center. A total of 204 PTC-confirmed patients were retrospectively read by a radiologist blinded to surgical pathology findings. The radiologist recorded multiple sonographic features, including ETE, loss of echogenic capsule, nodule vascularity, capsular abutment, and …

Identifying Predictors For Inflammation-Induced Preterm Birth: A Murine Study, Tzu Ning Liu Bs, Jose Galaz Md, Nardhy Gomez-Lopez Phd

Medical Student Research Symposium

Introduction: Preterm birth is the leading cause of neonatal morbidity and mortality worldwide. A large proportion of preterm deliveries is affected by intra-amniotic inflammation, which can occur in the presence (intra-amniotic infection) or absence (sterile intra-amniotic inflammation) of microbes. Studies have shown an association between intra-amniotic inflammation, cervical shortening, and changes in the cervicovaginal microbiome. However, their causal relationships are unknown. This study aims to determine the causality of intra-amniotic inflammation, cervical shortening, and cervicovaginal microbiome alterations.

Methods: Pregnant C57BL/6 dams received an ultrasound-guided intra-amniotic injection of an endotoxin lipopolysaccharide (LPS) or the alarmin interleukin-1 alpha (IL-1 alpha) on 16.5 …

Ultrasound Education Curriculum Increases First Year Student Visualization Ability Three-Fold, Joseph Files, Majd Faraj, Jared Hudson, Anna Kang, David Melville, Charles S. Day

Medical Student Research Symposium

Introduction: Ultrasound usage in identifying a subsheath within the first dorsal extensor compartment may be useful in determining cortisone shot effectiveness in alleviating pain for DeQuervain’s Tenosynovitis(1,2). However, no ultrasound educational curriculum has been established for non-radiologists(3-5). We hypothesize that an ultrasound training protocol will show marked improvement of anatomical knowledge and technical knowledge of how to utilize an ultrasound probe to visualize the first extensor compartment and any possible septation.

Materials & Methods: First-year medical students were polled for participation from a single medical school at a tertiary care academic medical center in the Midwest. Evaluations were developed and …

Making Waves: How Ultrasound-Targeted Drug Delivery Is Changing Pharmaceutical Approaches., Lauren J Delaney, Selin Isguven, John R Eisenbrey, Noreen J Hickok, Flemming Forsberg

Department of Radiology Faculty Papers

Administration of drugs through oral and intravenous routes is a mainstay of modern medicine, but this approach suffers from limitations associated with off-target side effects and narrow therapeutic windows. It is often apparent that a controlled delivery of drugs, either localized to a specific site or during a specific time, can increase efficacy and bypass problems with systemic toxicity and insufficient local availability. To overcome some of these issues, local delivery systems have been devised, but most are still restricted in terms of elution kinetics, duration, and temporal control. Ultrasound-targeted drug delivery offers a powerful approach to increase delivery, therapeutic …

Avoidable And Unavoidable Repeat Breast Core Needle Biopsies, Xiaoqin Wang, Fara Shikoh, Mauro Hanaoka, Aurela Clark

Radiology Faculty Publications

Background: Breast core needle biopsies are not perfect and could miss cancer. The need for a repeat breast core biopsy is not uncommon and can occur for a multitude of reasons. Radiologists should carefully correlate the pathology results with imaging features after each breast biopsy and must recognize why certain core biopsies must be repeated to avoid missed or delayed cancer diagnosis. In this review, we discuss the main reasons for repeat core biopsies via case presentation with radiological images and pathological correlation. This review will help multidisciplinary breast care team recognize when to repeat a biopsy to reduce false …

Ultrasound is a sound wave with frequencies ranging between 20 kHz and 20 MHz. Ultrasound is able to temporarily and repeatedly open the BBB safely and enhance chemotherapeutic delivery without adverse effects. This novel technique in drug delivery benefits from the powerful ability of ultrasound to produce cavitation activity. Cavitation is the generation and activity of gas-filled bubbles in a medium exposed to ultrasound. As the pressure wave passes through the media, gas bubbles expand at low pressure and contract at high pressure. This leads to oscillation which produces a circulating fluid flow known as microstreaming around the bubble with …
