The Use Of Fluid Haemodynamics In The Diagnosis Of Cardiovascular Disease, Andrew Malone

Doctoral

Currently the diagnostic methods used to detect cardiovascular disease largely rely on the inference of the presence of arterial stenosis. There is a clinical interest in the development of a diagnostic screening technique which can indicate the risk of developing cardiovascular disease at an early stage so that non-surgical treatments can be applied. The goal of this work was to develop and validate a diagnostic screening technique for cardiovascular disease using the mechanical biomarker wall shear stress. Improvements in wall shear stress measurements were made by using a 2D Fourier transform to extract additional spectral information from the ultrasound pulse …

Use Of Magnetic Resonance Image Registration To Estimate Displacement In The Human Earcanal Due To The Insertion Of In-Ear Devices, Simon Benacchio, Olivier Doutres, Arthur Varoquaux, Éric Wagnac, Arnaud Le Troter, Virginie Callot, Franck Sgard

Études primaires

In-ear devices are used in a wide range of applications for which the device's usability and/or efficiency is strongly related to comfort aspects that are influenced by the mechanical interaction between the device and the walls of the earcanal. Although the displacement of the earcanal walls due to the insertion of the device is an important characteristic of this interaction, existing studies on this subject are very limited. This paper proposes a method to estimate this displacement in vivo using a registration technique on magnetic resonance images. The amplitude, the location and the direction of the earcanal wall displacement are …

Protecting Patients Who Lack A Voice, Rainer Spiegel

Animal Sentience

Neither human young today nor future human generations nor non-human species have a voice in protecting the biosphere. Treves et al. propose courts and trustees for defending their interests. I describe an analogy with attempts to represent the interests of children and comatose patients in medicine.

Best Practices In Patellar Tendinopathy Management: An Evidence To Practice Review, Christopher J. Burcal, Adam B. Rosen, Tony Taylor, Mike Nicola

Clinical Practice in Athletic Training

Patellar tendinopathy (PT) is a degenerative condition that is common in sporting populations due to the loads placed on the tendon during dynamic activity. PT often occurs in overtraining situations; however, it may also occur in conjunction with and/or worsen through poor biomechanics, persistent inflammation, and altered movement patterns. Although sports medicine practitioners have evidence to support the prevalence of this injury, we do not have a strong base of evidence surrounding the contributing factors and pathophysiology that lead the pain and disability reported in patients with PT. The purpose of this evidence to practice review was to summarize a …

Genomic Prediction Of Relapse In Recipients Of Allogeneic Haematopoietic Stem Cell Transplantation., J Ritari, K Hyvärinen, S Koskela, M Itälä-Remes, R Niittyvuopio, A Nihtinen, U Salmenniemi, M Putkonen, L Volin, T Kwan, T Pastinen, J Partanen

Manuscripts, Articles, Book Chapters and Other Papers

Allogeneic haematopoietic stem cell transplantation currently represents the primary potentially curative treatment for cancers of the blood and bone marrow. While relapse occurs in approximately 30% of patients, few risk-modifying genetic variants have been identified. The present study evaluates the predictive potential of patient genetics on relapse risk in a genome-wide manner. We studied 151 graft recipients with HLA-matched sibling donors by sequencing the whole-exome, active immunoregulatory regions, and the full MHC region. To assess the predictive capability and contributions of SNPs and INDELs, we employed machine learning and a feature selection approach in a cross-validation framework to discover the …

An Investigation Of Therapeutic Rapport Through Prosody In Brief Psychodynamic Psychotherapy, Carolina De Pasquale, Charlie Cullen, Brian Vaughan

Conference Papers

Therapeutic alliance, a concept closely related to rapport, is one of the most important variables in psychotherapy. High degrees of synchrony/coordination in the therapeutic session are considered to contribute to rapport, and have received attention in the psychotherapy literature. Coordinative behaviours are observable in speech, and they manifest in phenomena such as prosodic accommodation, a dynamic phenomenon closely related to conversational success. A preliminary investigation of interpersonal prosodic dynamics in psychotherapy was performed on a database obtained in collaboration with the University of Padua, consisting of 16 recordings making up the entire course of a brief psychodynamic psychotherapy intervention for …

Feature-Guided Deep Radiomics For Glioblastoma Patient Survival Prediction, Zeina A. Shboul, Mahbubul Alam, Lasitha Vidyaratne, Linmin Pei, Mohamed I. Elbakary, Khan M. Iftekharuddin

Electrical & Computer Engineering Faculty Publications

Glioblastoma is recognized as World Health Organization (WHO) grade IV glioma with an aggressive growth pattern. The current clinical practice in diagnosis and prognosis of Glioblastoma using MRI involves multiple steps including manual tumor sizing. Accurate identification and segmentation of multiple abnormal tissues within tumor volume in MRI is essential for precise survival prediction. Manual tumor and abnormal tissue detection and sizing are tedious, and subject to inter-observer variability. Consequently, this work proposes a fully automated MRI-based glioblastoma and abnormal tissue segmentation, and survival prediction framework. The framework includes radiomics feature-guided deep neural network methods for tumor tissue segmentation; followed …

Development Of A Descriptive Model Of Flow Disruption Effect On Bypass Time In A Cardiovascular Operating Room, Timothy J. Disher

Doctoral Dissertations and Master's Theses

The current paper proposes utilizing extant flow disruption data, collected from two cardiovascular operating rooms, and utilizing that to develop a mathematical model. Of particular interest is bypass time which is a critical surgical phase, the length of which has been linked to post-operation complications such as hospital-borne infections and readmission. By developing a model that predicts bypass time, the present research can determine the impact by types of flow disruptions – coded based on the RIPCHORD-TWA taxonomy, team member disrupted, and where in the surgery the FD occurs.

After a review of literature, a variety of models were explored …

Harn, Lia Carolina Soares Medeiros, Wander De Jesus Jeremias, Liliane Maria Vidal Siqueira, Caroline Stephane Salviano Pereira, Maria Luysa Camargos Pedrosa, Nathalie Bonatti Franco Almeida, Aureo Almeida, Jose Roberto Lambertucci, Nidia Francisca De Figueiredo Carneiro, Paulo Marcos Zech Coelho, Refaella Fortini Queiroz Grenfell

Biological Sciences Faculty Publications

Background

Despite decades of use of control programs, schistosomiasis remains a global public health problem. To further reduce prevalence and intensity of infection, or to achieve the goal of elimination in low-endemic areas, there needs to be better diagnostic tools to detect low-intensity infections in low-endemic areas in Brazil. The rationale for development of new diagnostic tools is that the current standard test Kato-Katz (KK) is not sensitive enough to detect low-intensity infections in low-endemic areas. In order to develop new diagnostic tools, we employed a proteomics approach to identify biomarkers associated with schistosome-specific immune responses in hopes of developing …

Diagnosis Of Schistosoma Mansoni Infections: What Are The Choices In Brazilian Low-Endemic Areas?, Vanessa Silva-Moraes, Lisa M. Shollenberger, Liliane Maria Vidal Siqueira, William Castro-Borges, Donald A. Harn, Rafaella Fortini Queiroz E. Grenfell, Ana Lucia Teles Rabello, Paulo Marcos Zech Coelho

Biological Sciences Faculty Publications

The population of Brazil is currently characterised by many individuals harbouring low-intensity Schistosoma mansoni infections. The Kato-Katz technique is the diagnostic method recommended by the World Health Organization (WHO) to assess these infections, but this method is not sensitive enough in the context of low egg excretion. In this regard, potential alternatives are being employed to overcome the limits of the Kato-Katz technique. In the present review, we evaluated the performance of parasitological and immunological approaches adopted in Brazilian areas. Currently, the diagnostic choices involve a combination of strategies, including the utilisation of antibody methods to screen individuals and then …

Illumination Of The Golgi Apparatus Of Pathogenic And Nonpathogenic Naegleria Species, Tyler M. Poe

Theses and Dissertations

In this study, Naegleria fowleri, a pathogenic amoeba and the causative agent of Primary Amebic Meningoencephalitis (PAM), was utilized to determine the presence or absence of classically conserved Golgi molecules featured in the expression of a Golgi apparatus. Previous studies concluded no Golgi expression via light microscopy and transmission electron microscopy, but a recent report on Naegleria gruberi indicated the presence of dispersed Golgi tubules. Non-pathogenic species of the Naegleria genus such as Naegleria gruberi 30540 and Naegleria lovaniensis 30569 were utilized in Western immunoblot analysis compared to reduced whole-cell lysate proteins of two strains of N. fowleri and …

Monitoring Melanoma Recurrence With Circulating Tumor Dna: A Proof Of Concept From Three Case Studies, Ashleigh C. Mcevoy, Michelle R. Pereira, Anna Reid, Robert Pearce, Lester Cowell, Zeyad Al-Ogaili, Muhammad A. Khattak, Michael Millward, Tarek M. Meniawy, Elin S. Gray, Melanie R. Ziman

Research outputs 2014 to 2021

Background: A significant number of melanoma patients experience recurrence to distant sites, despite having had surgical treatment of the primary lesion, with curative intent. Monitoring of patients for early evidence of disease recurrence would significantly improve management of the disease, allowing timely therapeutic intervention. Circulating tumor DNA (ctDNA) is becoming a well-recognized biomarker for monitoring malignancies and has, in a few studies, been shown to signify disease recurrence earlier than conventional methods.

Methods: We performed a retrospective analysis of plasma ctDNA using droplet digital PCR (ddPCR) in 30 primary melanoma patients with tumors harboring BRAF, NRAS or TERT promoter mutations. …

Research outputs 2014 to 2021

Cutaneous melanoma circulating tumour cells (CTCs) are phenotypically and molecularly heterogeneous. We profiled the gene expression of CTC subpopulations immunomagnetic-captured by targeting either the melanoma-associated marker, MCSP, or the melanoma-initiating marker, ABCB5. Firstly, the expression of a subset of melanoma genes was investigated by RT-PCR in MCSP-enriched and ABCB5-enriched CTCs isolated from a total of 59 blood draws from 39 melanoma cases. Of these, 6 MCSP-and 6 ABCB5-enriched CTC fractions were further analysed using a genome-wide gene expression microarray. The transcriptional programs of both CTC subtypes included cell survival maintenance, cell proliferation, and migration pathways. ABCB5-enriched CTCs were specifically characterised …

The Mulligan Concept In The Treatment Of Anterior Knee Pain, Karla S. Judge, Alan Nasypany, Russell T. Baker, James May

Clinical Practice in Athletic Training

The purpose of the disablement model case study was to describe the case of a collegiate basketball player suffering from anterior knee pain (AKP). The patient had been experiencing AKP while participating in pre-season basketball related activities (playing, weight lifting, and conditioning) for approximately six weeks. As the intensity increased, the pain became intolerable. Previously, the patient had missed a significant amount of off-season workouts due to surgery for an upper extremity injury sustained during the competitive season. The patient reported tenderness at the inferior pole of the patella, and at the tibial tuberosity. There was no joint line tenderness, …

Elbow Injury Prevention In Youth Dominican Baseball Players: A Training Intervention Pilot Study, Chelsey Erbaugh Franz, Dawn Hall-Bibb, Myra Stockdale, Aliya Thompson, Bailey Biggs

Internet Journal of Allied Health Sciences and Practice

Background: Research suggests deficits in shoulder and elbow strength and flexibility may explain the role of elbow injuries in overhead athletes, specifically ulnar collateral ligament (UCL) injury in baseball players. Significant damage to this ligament typically requires operative care for continued activity in the sport. Several studies have demonstrated the success of rehabilitation programs post-surgery; however, few studies have examined the role of UCL injury prevention programs. A recognized upper extremity (UE) injury prevention method is the Thrower’s Ten Program. This program may create elbow stability when pitching and throwing, theoretically reducing the risk of UCL injury. Purpose: The purpose …

In 2017 approximately 50 million people worldwide were living with dementia. With Alzheimer’s disease (AD), accounting for 50-70% of dementia cases making this debilitating disease, with no current effective prevention, treatment or cure, a critical healthcare concern. Genome wide association studies (GWAS) have identified a number of risk genes for late onset AD (LOAD); Apolipoprotein E (APOE), a gene involved in the cholesterol/lipid pathway is considered the gene with the greatest risk. The third most associated AD risk gene is Clusterin (CLU), is also involved in the cholesterol/lipid pathway. CLU has been implicated in both …

Pain, Severity, And Attentional Capacity Following Acute Musculoskeletal Injury, Rebekah F. Roessler

College of Graduate Studies: Theses & Dissertations

Background: As recreational activities grow in popularity, there is a concurrent rise in musculoskeletal injury. Injury severity is determined through clinical evaluation and defined by a grading scale. Pain is included in the definition of each injury grade, despite the lack of any conclusive evidence relating injury severity and the associated pain. Additionally, previous studies report impairments in cognitive performance due to chronic and acute pain. The aim of this study is to determine the relationship between the perceived pain intensity and the clinically diagnosed severity of an acute musculoskeletal injury, and to determine if attentional capacity is influenced by …

Non-Human Animals Providing Rescue In Medical Emergencies, Rainer Spiegel

Animal Sentience

In their target article, Chapman & Huffman challenge the quotation of Sir William Osler that the desire to take medication distinguishes humans from non-human animals. They provide examples of self-medication in non-human animals. Based on these examples, it can be inferred that non-human animals practice at least some form of medicine for symptom control. I would like to extend this view by showing that non-human animals not only provide self-medication, but also rescue others facing emergencies.

Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. Affected women frequently have metabolic disturbances including insulin resistance and dysregulation of glucose homeostasis. PCOS is diagnosed with two different sets of diagnostic criteria, resulting in a phenotypic spectrum of PCOS cases. The genetic similarities between cases diagnosed based on the two criteria have been largely unknown. Previous studies in Chinese and European subjects have identified 16 loci associated with risk of PCOS. We report a fixed-effect, inverse-weighted-variance meta-analysis from 10,074 PCOS cases and 103,164 controls of European ancestry and characterisation of PCOS related …

Pasnet: Pathway-Associated Sparse Deepneural Network For Prognosis Prediction From High-Throughput Data, Jie Hao, Youngsoon Kim, Tae-Kyung Kim, Mingon Kang

Faculty Articles

Background: Predicting prognosis in patients from large-scale genomic data is a fundamentally challenging problem in genomic medicine. However, the prognosis still remains poor in many diseases. The poor prognosis maybe caused by high complexity of biological systems, where multiple biological components and their hierarchical relationships are involved. Moreover, it is challenging to develop robust computational solutions with high-dimension, low-sample size data. Results: In this study, we propose a Pathway-Associated Sparse Deep Neural Network (PASNet) that not only predicts patients’ prognoses but also describes complex biological processes regarding biological pathways for prognosis. PASNet models a multilayered, hierarchical biological system of genes …

Multiple Regression Models To Analyze Length Of Hospitalization Due To Nosocomial Infections In U.S. Hospitals, Ernest M. Oleksy

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Nosocomial diseases are a serious concern and detriment to hospitals’ abilities to provide appropriate patient care. Bearing this in mind, an effort must be made to determine whether infection surveillance and control programs have reduced the rates of nosocomial infection at U.S. hospitals. The data that were studied were obtained as part of the Study on the Efficacy of Nosocomial Infection Control (SENIC) and used to develop a model of what variables most contribute to a patient’s length of stay at the Cleveland Clinic (Quade et al, 1980).

Methods: Studies were found using PubMed with the search term, “on and off pump CABG” which yielded 1736 studies. After assessing for records within 5 years the search was narrowed to 370 articles and then down to 353 because some articles were not available in full-text. Our search was then divided into first looking at randomized control trials and meta-analysis availability from the 353 articles meeting our criteria. After narrowing our search for …

Change In Brain Volume And Cortical Thickness After Behavioral And Surgical Weight Loss Intervention, Cara Bohon, Allan Geliebter

Lander College of Arts and Sciences Publications and Research

Obesity is associated with reduced cortical thickness and brain volume, which may be related to poor nutrition. Given that brain atrophy in anorexia nervosa recovers with nutritional improvements and weight gain, it is worth examining how brain structure changes at the other end of the weight spectrum with weight loss. Thus, this study aimed to examine change in cortical thickness and brain volume in 47 patients with severe obesity who participated in no treatment, behavioral weight loss, or bariatric surgery. T1-weighted MRI scans were conducted pre-treatment and approximately four months later. Measures of cortical thickness, gray matter volume, and white …

BACKGROUND: Wrist-worn activity monitors are often used to monitor heart rate (HR) and energy expenditure (EE) in a variety of settings including more recently in medical applications. The use of real-time physiological signals to inform medical systems including drug delivery systems and decision support systems will depend on the accuracy of the signals being measured, including accuracy of HR and EE. Prior studies assessed accuracy of wearables only during steady-state aerobic exercise.

OBJECTIVE: The objective of this study was to validate the accuracy of both HR and EE for 2 common wrist-worn devices during a variety of dynamic activities that …

Innocent Heart Murmur., Arpan R. Doshi

Manuscripts, Articles, Book Chapters and Other Papers

Heart murmur is the most common reason for a referral to a pediatric cardiologist. Virtually all children have a heart murmur during their childhood. Less than 1% of murmurs are pathological in children. Innocent/functional heart murmur is the most common type of heart murmur. There are multiple theories proposed to identify etiology of innocent heart murmur with varying consensus, but everybody agrees that innocent heart murmur does not carry any morbidity or mortality risk. Even today, heart murmur is associated with high physician uncertainty and parental anxiety. Extensive cardiac evaluation for such a benign finding is also associated with high …

Joint Coordination Variability In Anterior Cruciate Ligament Reconstructed Subjects During Stair Ambulation Using A Vector Coding Technique, Bryan R. Simrak

Theses and Dissertations (ETD)

Anterior cruciate ligament (ACL) rupture is a common injury, with an estimated incidence of 120,000 to 200,000 per year in the United States. ACL reconstruction surgery is the standard treatment for this injury to restore knee joint stability and function. While surgical reconstruction has been shown to restore laxity of the knee, current literature lacks consensus on return to normal knee joint kinematics following surgery. Additionally, re-injury is a major risk for those who return to sports activity after reconstruction surgery. Dynamical systems methods for quantifying joint coordination variability have been explored as a method for detecting differences between ACL …
