Therapeutic Exercises: A Conservative Approach To The Treatment Of Chronic Low Back Pain, Austin England

University Honors Program

Chronic low back pain is becoming a worldwide epidemic; millions suffer from this condition every year. Back pain is one of the most frequent reasons cited for patient visits every year. It is the second most reason for days of missed work following the flu. Chronic low back pain is defined as pain persisting in the low back region for greater than three months. This pain may originate from a variety of factors. These factors can include, but are not limited to injury, disease, or different stressors on the body. Pain in the low back region may be felt as …

The Role Of Traditional Chinese Medicine In The Management Of Chronic Pain: A Biopsychosocial Approach, John Burns, Tiffany A. Mullen

Journal of Patient-Centered Research and Reviews

The National Institute of Medicine revealed that chronic pain affects more than 100 million adults in the United States, citing chronic pain as the leading reason patients seek medical care. Pain is also an extremely costly problem, with $635 billion per year spent nationally, more than cancer, heart disease and diabetes combined. The biomedical model of chronic pain management has largely revolved around the use of narcotic analgesics for pain control. Unfortunately, this corresponds to a growth in the rate of abuse, misuse and overdose of these drugs. Additionally, there is an inherent failure rate to the myriad procedures used …

Echocardiographic Predictors Of Admission Among Patients With Heart Failure With Reduced Ejection Fraction, Chi C. Cho, Yang Shi, Robyn Shearer, Nasir Z. Sulemanjee, Dianne L. Zwicke, T. Edward Hastings, Omar M. Cheema, Vinay Thohan

Journal of Patient-Centered Research and Reviews

Background: Congestive heart failure afflicts 5.7 million people in the United States with annual incidence of 600,000 and mortality of 280,000. Heart failure accounts for greater than 1 million hospitalizations annually and the single largest inpatient Medicare expense. As the U.S. population ages and greater emphasis is placed on population health as a means to bend projected health care expenditures, large health care organizations will need to develop algorithms to identify patients at high risk with heart failure and possibly preempt hospitalizations. Doppler echocardiography is routinely performed in clinical assessment of severe heart failure.

Purpose: We sought to determine echocardiographic …

Cardiopulmonary Exercise Testing-Based Algorithm And Its Usefulness In Clinical Cardiology, Mirza Nubair Ahmad, Syed Hasan Yusuf, Rafath Ullah, Mary Ellis, Haroon Yousaf, Timothy E. Paterick, Khawaja Afzal Ammar

Journal of Patient-Centered Research and Reviews

Background: Only cardiopulmonary exercise (CPX) testing provides information on the ability of the cardiovascular system to meet the body’s metabolic demands in terms of oxygen consumption (VO₂) and carbon dioxide production (VCO₂). However, CPX testing is underutilized by cardiologists due to complex diagnostic algorithms involving up to 30 variables as well as lack of validation studies. In addition, CPX also provides oxygen (O₂) pulse as a continuous measure of stroke volume, which is its superiority to other stress modalities in which systolic function is measured at peak stress and rest. In the literature, it …

Maternal Intuition Of Fetal Gender, Michael P. Mcfadzen, David P. Dielentheis, Ronda Kasten

Journal of Patient-Centered Research and Reviews

Background: Many pregnant mothers feel they have a perception or intuition as to the gender of their unborn baby. There is very little published scientific literature regarding this topic. The study’s goal is to determine accuracy of mothers’ perceptions as to gender of their unborn babies. Many scientists believe a pregnant woman could not determine her baby’s gender by intuition, with a 50% probability of correctly determining the gender. This study should be considered fun science.

Purpose: To objectively measure a pregnant mother’s perception as to the gender of her unborn baby and compare to sonographically proved gender. The study …

Feasibility Of Atrial Delivery And Tracking Of Stem Cells In A Porcine Model, Nina Garlie, Timothy Hacker, Eric G. Schmuck, Jill Koch, Jayant Khitha, Amish Raval, Indrajit Choudhuri

Journal of Patient-Centered Research and Reviews

Background: Many patients undergoing open heart surgery have sinus node dysfunction and atrial fibrillation, leading to adverse outcomes. Mesenchymal stem cells (MSC) delivered at the time of surgery may have a reparative effect on atrial tissue, thereby improving sinus node function and reducing or preventing atrial fibrillation. Stem cell delivery to the atrium is entirely unstudied. This is a significant gap in medical research, as atrial disease contributes significantly to health care costs.

Purpose: The purpose of this pilot study is to establish a technique to deliver MSC to the atria through an open-chest model, to assess the safety of …

Real-World Relevance Of Manual Electrocardiography Qt Interval Measurement, Satish Velagapudi, Zahra Nur Khaled, Bilal Omery, Firas Zahwe, Michael Anigbogu, Sarah Zukkoor, Indrajit Choudhuri

Journal of Patient-Centered Research and Reviews

Background: Electrocardiography (ECG) QT interval (QTI) prolongation independently predicts sudden death. Hospitalized patients are commonly exposed to multiple QT-prolonging drugs, and manual measurement of ECG QTI based on identifying the intersection of isoelectricity with the tangent to the terminal phase T-wave slope (QTTTT) is advocated due to inaccuracies in automated detection algorithms that may imprecisely identify QT duration.

Purpose: We evaluated the performance of QTTTT compared to a standard automated (12SL, GE Healthcare) method (QT-12SL).

Methods: Consecutively obtained ECGs of 250 hospitalized patients were reviewed. The QTI in leads II, aVR, V5 and V6 determined by QT-12SL and QTTTT were …

Partial Covariance Based Functional Connectivity Computation Using Ledoit-Wolf Covariance Regularization, Matthew R. Brier, Anish Mitra, John E. Mccarthy, Beau M. Ances, Abraham Z. Snyder

Mathematics Faculty Research

Highlights •We use the well characterized matrix regularization technique described by Ledoit and Wolf to calculate high dimensional partial correlations in fMRI data. •Using this approach we demonstrate that partial correlations reveal RSN structure suggesting that RSNs are defined by widely and uniquely shared variance. •Partial correlation functional connectivity is sensitive to changes in brain state indicating that they contain functional information. Functional connectivity refers to shared signals among brain regions and is typically assessed in a task free state. Functional connectivity commonly is quantified between signal pairs using Pearson correlation. However, resting-state fMRI is a multivariate process exhibiting a …

Pharmacy Faculty Articles and Research

Ligand-directed targeting and capturing of cancer cells is a new approach for detecting circulating tumor cells (CTCs). Ligands such as antibodies have been successfully used for capturing cancer cells and an antibody based system (CellSearch®) is currently used clinically to enumerate CTCs. Here we report the use of a peptide moiety in conjunction with a microcantilever array system to selectively detect CTCs resulting from cancer, specifically breast cancer. A sensing microcantilever, functionalized with a breast cancer specific peptide 18-4 (WxEAAYQrFL), showed significant deflection on cancer cell (MCF7 and MDA-MB-231) binding compared to when exposed to noncancerous (MCF10A and HUVEC) cells. …

Physical Therapy Faculty Publications

Breast cancer is the most commonly diagnosed cancer in women in the United States. The treatment for breast cancer occurs along a protracted time period and includes many different disease treatment modalities. These treatments carry with them a large number of adverse effects that negatively impact function in both the short term and long term. It is necessary for rehabilitation providers to interface with patients being treated for breast cancer throughout the continuum of care so that interval assessments can be conducted to identify emerging impairments and alleviate disability. To achieve this, the rehabilitation provider must have an understanding of …

Quantification Of Blood Flow Velocity Using Color Sensing, Aditya Deepak Sanghani

Master's Theses

Blood flow velocity is an important parameter that can give information on several pathologies including atherosclerosis, glaucoma, Raynaud’s phenomenon, and ischemic stroke [2,5,6,10]. Present techniques of measuring blood flow velocity involve expensive procedures such as Doppler echocardiography, Doppler ultrasound, and magnetic resonance imaging [11,12]. They cost from $8500-$20000. It is desired to find a low-cost yet equally effective solution for measuring blood flow velocity. This thesis has a goal of creating a proof of concept device for measuring blood flow velocity.

Finger blood flow velocity is investigated in this project. The close proximity to the skin of the finger’s arteries …

Factors Associated With Colorectal Cancer Screening Among Younger African American Men: A Systematic Review, Charles R. Rogers, Patricia Goodson, Margaret Foster

Journal of Health Disparities Research and Practice

Of cancers affecting both men and women, colorectal cancer (CRC) is the second leading cancer killer among African Americans in the U.S. Compared to White men, African American men have incidence and mortality rates 25% and 50% higher from CRC. Despite the benefits of early detection and the availability of effective screening, most adults over age 50 have not undergone testing, and disparities in colorectal cancer screening (CRCS) persist. Owing to CRC’s high incidence and younger age at presentation among African American men, CRCS is warranted at age 45 rather than 50. However, the factors influencing young adult (i.e., age < 50) African American men’s intention to screen and/or their CRCS behaviors has not been systematically assessed. To assess whether the factors influencing young adult African American men’s screening intentions and behaviors are changeable through structured health education interventions, we conducted a systematic review, with the two-fold purpose of: (1) synthesizing studies examining African American men's knowledge, beliefs, and behaviors regarding CRCS; and (2) assessing these studies’ methodological quality. Utilizing Garrard’s Matrix Method, a total of 28 manuscripts met our inclusion/exclusion criteria: 20 studies followed a non-experimental research design, 4 comprised a quasi-experimental design, and 4, an experimental design. Studies were published between 2002 and 2012; the majority, between 2007 and 2011. The factors most frequently assessed were behaviors (79%), beliefs (68%), and knowledge (61%) of CRC and CRCS. Six factors associated with CRC and CRCS emerged: previous CRCS, CRC test preference, perceived benefits, perceived barriers, CRC/CRCS knowledge, and physician support/recommendation. Studies were assigned a methodological quality score (MQS – ranging from 0 to 21). The mean MQS of 10.9 indicated these studies were, overall, of medium quality and suffered from specific flaws. Alongside a call for more rigorous research, this review provides important suggestions for practice and culturally relevant interventions.

The Simple View of reading emphasizes the critical role of two factors in normal reading skills: word recognition and reading comprehension. The current study aims to identify the anatomical support for aspects of reading performance that fall within these two components. Fractional anisotropy (FA) values were obtained from Diffusion Tensor images in twenty-one typical adolescents and young adults using the Tract Based Spatial Statistics (TBSS) method. We focused on the Arcuate Fasciculus (AF) and Inferior Longitudinal Fasciculus (ILF) as fiber tracts that connect regions already implicated in the distributed cortical network for reading. Our results demonstrate dissociation between word-level and …

Initial Validation Of A Novel Method Of Presurgical Language Localization Through Functional Connectivity (Fcmri), Stephanie M. Noble, Dustin Scheinost, Susan Y. Bookheimer, Patricia Walshaw, R Todd Constable, Christopher F. Benjamin

Yale Day of Data

OBJECTIVE: Neurosurgery is potentially curative in chronic epilepsy but can only be offered to patients if the surgical risk to language is known. Clinical functional magnetic resonance imaging (fMRI) is an ideal, noninvasive method for localizing language cortex yet remains to be validated for this purpose. We have recently presented a novel method for localizing language cortex. Here we present a preliminary evaluation of this method’s validity. We hypothesized language regions identified using this novel method would demonstrate stronger functional connectivity than randomly generated set of proximal networks. METHOD: fMRI data were collected from sixteen temporal lobe patients …

Arterial Or Venous: Where Are The Circulating Tumor Cells?, Elin S. Gray

Research outputs 2014 to 2021

The study of circulating tumor cells (CTCs) has been largely confounded by the low number of these cells in the blood stream amid billions of other cells. To overcome this challenge numerous methodologies for CTC isolation have been described. Photoacoustic flow cytometry (Nedosekin et al., 2013), dielectrophoresis array (Maltoni et al., 2015) and microfluidics (Warkiani et al., 2015) are among the most sophisticated of these methodologies. However, methods based on immunecapture and immunestaining are still the more frequently utilized, with CellSearch® remaining the most commonly used method to date and the only US FDA approved (Alix-Panabieres and Pantel, 2014). Irrespective …

The most important failure in pandemic planning is the lack of standards or guidelines regarding what it means to be ‘prepared’. The aim of this study was to assess the preparedness of acute hospitals in the Republic of Ireland for an influenza pandemic from an infection control perspective.

Review Of Fluorescence Guided Surgery Visualization And Overlay Techniques, Jonathan T. Elliott, Alisha V. Dsouza, Scott C. Davis, Jonathan D. Olson, Keith Paulsen, David Roberts, Brian Pogue

Dartmouth Scholarship

In fluorescence guided surgery, data visualization represents a critical step between signal capture and display needed for clinical decisions informed by that signal. The diversity of methods for displaying surgical images are reviewed, and a particular focus is placed on electronically detected and visualized signals, as required for near-infrared or low concentration tracers. Factors driving the choices such as human perception, the need for rapid decision making in a surgical environment, and biases induced by display choices are outlined. Five practical suggestions are outlined for optimal display orientation, color map, transparency/alpha function, dynamic range compression, and color perception check.
