Bystander Performance Using Automated External Defibrillators During Simulated Cardiac Arrest, Richard N. Bradley, Lynda M. Schoenstein, Wesley H. Hamilton, Mark R. Boyle

Richard N Bradley

Objective: Automated external defibrillators (AEDs) are becoming widely available to the public. This study examined the hypothesis that less than 75% of the general population can defibrillate using an AED in less than three minutes.

Methods: This was a survey of the behavior of individuals over age 12 in a major airport on Jan. 2–3, 2003. After obtaining consent, an investigator told the subject that he/she was walking down the concourse and saw a person collapse. The subject demonstrated his/her response, using only a telephone and an AED simulating ventricular fibrillation. Data were analyzed using a one-sample ...

Electronic Desalting For Controlling The Ionic Environment In Droplet-Based Biosensing Platforms, Vikhram Vilasur Swaminathan, Piyush Dak, Bobby Reddy Jr, Eric Salm, Carlos Duarte-Guevara, Yu Zhong, Andrew Fischer, Yi-Shao Liu, Rashid Bashir

Birck and NCN Publications

The ability to control the ionic environment in saline waters and aqueous electrolytes is useful for desalination as well as electronic biosensing. We demonstrate a method of electronic desalting at micro-scale through on-chip micro electrodes. We show that, while desalting is limited in bulk solutions with unlimited availability of salts, significant desalting of ≥1 mM solutions can be achieved in sub-nanoliter volume droplets with diameters of ∼250 μm. Within these droplets, by using platinum-black microelectrodes and electrochemical surface treatments, we can enhance the electrode surface area to achieve >99% and 41% salt removal in 1 mM and 10 mM salt ...

Lead Burden As A Factor For Higher Complication Rate In Patients With Implantable Cardiac Devices, Christopher Kolibash, Naoyo Mori, Jasbir Sra, Masood Akhtar, M. Eyman Mortada

Journal of Patient-Centered Research and Reviews

Purpose

Lead revisions have increased over the last decade. Patients who do not undergo lead extraction face an increased lead burden. Consequences of increased lead burden have not been fully defined. We sought to characterize the complication rate and outcomes in patients with sterile redundant leads.

Methods

We retrospectively reviewed 242 consecutive patients [mean age 74 ± 12 years; 66.9% male] who underwent lead revision that resulted in an abandoned lead from January 2005 to June 2010. Patients were placed in a cohort based on number of leads after last recorded procedure (Group A: ≤2 [n=58]; Group B: 3-4 ...

The Clinical Breast Examination: A Useful Screening Tool?, Jennifer Lo

Journal of Patient-Centered Research and Reviews

The standardization of the clinical breast examination as a screening tool for breast cancer has been a topic of controversy. Current recommendations vary significantly from organization to organization without consensus. There currently does not seem to be sufficient evidence regarding overall survival benefit of the clinical breast exam. However, as adjunct screening with mammography, it may help find earlier breast cancers and the up to 5–10% of cancers missed by mammography. The most appropriate standardized protocol may be that the clinical breast exam can be performed at the discretion of the provider and patient, with more inclination toward use ...

What Are The Recommended Timing And Screening Modalities For Women At Higher Risk Of Developing Breast Cancer? A Clin-Iq, Summer Jatala, Shawn Fitzgerald, Pamela Tietze, Kalyanakrishnan Ramakrisnan, Laine H. Mccarthy, Elizabeth Wickersham

Journal of Patient-Centered Research and Reviews

Early detection of breast cancer is desirable to prevent progression to advanced disease. This subject has been one of significant study and debate for women at normal risk, and recommendations continue to evolve. However, with regard to women at high risk, the recommendations from various health care professional organizations, including the U.S. Preventive Services Task Force, are different and also inconsistent concerning when to begin screening and which modalities should be used. We review several randomized controlled trials and consensus opinions regarding when to begin screening for breast cancer and how to best screen women at high risk. Specifically ...

Designing Electronics For An Artificial Leg, Taylor Barto

The Downtown Review

A regenerative prosthesis is modeled and simulated. The simulation is optimized with the biogeography-based optimization algorithm to obtain desired knee angle tracking with a reference knee trajectory and to regenerate energy. The prosthesis is able to track a reference knee angle with a 5.1 degree error averaged over an entire stride and regenerate some energy throughout the stride.

Mathematics Faculty Publications

Previous results on the use of joint entropy for detection of targeted nanoparticles accumulating in the neovasculature of MDA435 tumors [Fig. 7 of M. S. Hughes et al., J. Acoust. Soc. Am. 133, 283–300 (2013)] are extended, with sensitivity improving by nearly another factor of 2. This result is obtained using a “quasi-optimal” reference waveform in the computation of the joint entropy imaging technique used to image the accumulating nanoparticles.

Absence Of Jc Viremia In A Case With Jc Virus Nephropathy: A Case Report And Literature Review, Samer Bani-Hani Md, Facp, Uma Gunasek Md

Tennessee Medicine E-Journal

BK virus associated nephropathy (BKVAN) is an important cause of graft dysfunction with a high rate of graft loss. Current literature describes the pathophysiology of Polyoma Virus Associated Nephropathy (PVAN) induced by BKV but it lacks detailed definition of allograft nephropathy induced by JC virus (JCV). BKVAN is typically associated with BK Viremia, and the latter is the most commonly used screening measure for BKVAN in most transplant centers [1]. We are reporting a case of JCV associated nephropathy in renal allograft recipient who did not have JC viremia during the entire course of his disease and did not respond ...

Nanopulse Generators: Their Design And Application To Cancer Therapy Studies, Daniel P. Wernig

Senior Honors Theses

Effective nanopulse generators have become critical in recent decades concerning the study of subcellular affects in response to nanosecond pulsed electric fields. It has been observed that nanosecond duration electric pulses can target intracellular organelles, ultimately leading to cell apoptosis, suggesting the possibility of a new, minimally invasive, low risk cancer therapy methodology. The standard topology for developing a medical nanopulser is the Blumlein “transmission line” approach. This approach relies on the nearly infinitesimal, yet finite amount of time required for an electromagnetic field to propagate down a short transmission line. Prior to design, requirements and constraints must be defined ...

Raman Microspectroscopy For The Early Detection Of Pre-Malignant Changes In Cervical Tissue, Nosheen Rashid, Haq Nawaz, Kelvin W. Poon, Franck Bonnier, Salih Bakhiet, Cara Martin, John O'Leary, Hugh J. Byrne, Fiona M. Lyng

Articles

Cervical cancer is the third most common cancer affecting women worldwide. The mortality associated with cervical cancer can, however, be significantly reduced if the disease is detected at the pre-malignant stage. The aim of this study was to evaluate the potential of Raman microspectroscopy for elucidation of the biochemical changes associated with the pre-malignant stages of cervical cancer. Formalin fixed paraffin preserved tissue sections from cervical biopsies classified as negative for intraepithelial lesion and malignancy (NILM), low grade squamous intraepithelial lesion (LSIL) or high grade squamous intraepithelial lesion (HSIL) were analysed by Raman spectral mapping. Raman mapping, with K-Means Cluster ...

Acceptability Of A Novel Smartphone Application For Rhythm Evaluation In Patients With Atrial Fibrillation, Daniel J. Amante, Thomas M. English, Jane S. Saczynski, Nada Esa, Iryna Nieto, Ki H. Chon, David D. Mcmanus

Community Engagement and Research Symposium

Background: Investigators at UMass Medical School and WPI co-developed a novel smartphone application (app), PULSESMART, that detects atrial fibrillation (AF). AF is the world’s most common, serious heart rhythm problem. In its early stages, most cases of AF are paroxysmal (pAF), making them difficult to identify early in the course of disease. Long-term cardiac monitoring is frequently needed to diagnose and prevent complications from AF, such as stroke. Home monitoring for AF can be clinically impactful but existing technologies have cost or methodological limitations. Data are needed on the potential acceptability and usability of heart rhythm monitoring applications.

What Is Pfapa And Why Does It Matter?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

PFAPA, the syndrome of periodic fever, aphthous stomatitis, pharyngitis and cervical lymphadentitis, is an uncommon disease of episodic immune dysregulation that usually begins in early childhood. Symptoms occur at regular, predictable intervals, with healthy periods in between, and generally include the namesake signs and various other constitutional symptoms such as fever and fatigue. The etiology is unknown and there is no definitive diagnostic test or treatment. Uncertainty during the period of searching for a diagnosis may be disconcerting to the family and the clinician. Single-dose prednisone is effective for resolving the fever of PFAPA episodes within just a few hours ...

Anesthesiology and Critical Care Medicine Faculty Publications

Introduction: Patients with distributive shock who require high dose vasopressors have a high mortality. Angiotensin II (ATII) may prove useful in patients who remain hypotensive despite catecholamine and vasopressin therapy. The appropriate dose of parenteral angiotensin II for shock is unknown.

Methods: In total, 20 patients with distributive shock and a cardiovascular Sequential Organ Failure Assessment score of 4 were randomized to either ATII infusion (N?=?10) or placebo (N?=?10) plus standard of care. ATII was started at a dose of 20?ng/kg/min, and titrated for a goal of maintaining a mean arterial pressure (MAP) of 65 ...

Normative Scores For The Nih Toolbox Dynamic Visual Acuity Test From 3 To 85 Years, Carol Li, Jennifer L. Beaumont, Rose Marie Rine, Jerry Slotkin, Michael C. Schubert

Physical Therapy Faculty Research

As part of the National Institutes of HealthToolbox initiative, a computerized test of dynamic visual acuity (cDVA) was developed and validated as an easy-to-administer, cost- and timeefficient test of vestibular and visual function. To establish normative reference values, 3,992 individuals, aged 3–85 years, without vestibular pathology underwent cDVA testing at multiple clinical research testing facilities across the United States. Test scores were stratified by sociodemographic characteristics. cDVA was worse in males (p <0.001) and those subjects 50 years or older, while there was no difference in dynamic visual acuity across age groups binned from 3 to 49 years. Furthermore, we used these normative cDVA data as a criterion reference to compare both the long (validated) and short versions of the test. Both versions can distinguish between those with and without vestibular pathology (p D0.0002 long; p D0.0025 short). The intraclass correlation coefficient between longand short-cDVA tests was 0.86.
