Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass 2021 The Graduate Center, City University of New York

Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support ...

Removal Of Impella In The Setting Of Left Ventricular Thrombus: A Potential Indication For Cerebral Embolic Protection Devices, Miro Asadourian, Avinash Sharma, Richard Kiel, Felice Lin, Manminder Bhullar

The VAD Journal

Successful percutaneous mechanical circulatory support (MCS) has been used for acute stabilization of cardiogenic shock (CS). Improved survival outcomes have been observed in patients with CS from an acute myocardial infarction (AMI) who undergo implantation of left ventricular (LV) to ascending aorta rotodynamic pumps, such as the Impella® device (Abiomed). However, thrombotic events are a known complication of such devices in poor flow states such as CS. There is limited evidence regarding the management of patients who develop an LV thrombus after Impella insertion. Currently, the Sentinel cerebral protection system (SCPS, Boston Scientific) is the only FDA-approved device for cerebral ...

The global pandemic caused by COVID-19 placed constraints on several aspects of normal life, especially those of higher level education. While many programs moved to teaching in a strictly online format, there are some courses in which this structure was not appropriate. This study observed the outcome of the adapted course structure employed at Quillen College of Medicine during their Gross Human Anatomy course. Through a voluntary survey and multiple independent t-tests, it was demonstrated that the students who took the adapted course performed, on average, 2 points lower on each exam than previous classes. Also, this study showed that ...


Design And Control Of A Peristaltic Pump To Simulate Left Atrial Pressure In A Conductive Silicone Model, Jeremy Collins 2021 University of Arkansas, Fayetteville

Design And Control Of A Peristaltic Pump To Simulate Left Atrial Pressure In A Conductive Silicone Model, Jeremy Collins

Mechanical Engineering Undergraduate Honors Theses

According to the CDC, atrial fibrillation is responsible for more than 454,000 hospitalizations and approximately 158,000 deaths per year. A common treatment for atrial fibrillation is catheter ablation, a process in which a long flexible tube is guided through the femoral artery and to the source of arrhythmia in the heart, where it measures the electrical potential at various locations and converts problematic heart tissue to scar tissue via ablation. This paper details the design and control of a low-cost ($400) peristaltic pump system using repetitive control to replicate blood pressure in the left atrium in a conductive ...

Supply, Demand, And Quality: A Three-Pronged Approach To Blood Product Management In Developing Countries, Kyle L. Gress, Karina Charipova, Ivan Urits, Omar Viswanath, Alan D. Kaye

Journal of Patient-Centered Research and Reviews

While transfusion of blood and blood products is instinctively linked to the provision of emergent care, blood and blood products are also routinely used for the treatment of subacute and chronic conditions. Despite the efforts of the World Health Organization and others, developing countries are faced with a three-part problem when it comes to access to and delivery of transfusions: insufficient supply, excessive demand, and inadequate quality of available supply. Developing countries rely heavily on replacement and remunerated donors rather than voluntary nonremunerated donors due to concerns regarding donation- and transfusion-transmitted infection as well as local and cultural beliefs. While ...

Autosomal genetic analyses of blood lipids have yielded key insights for coronary heart disease (CHD). However, X chromosome genetic variation is understudied for blood lipids in large sample sizes. We now analyze genetic and blood lipid data in a high-coverage whole X chromosome sequencing study of 65,322 multi-ancestry participants and perform replication among 456,893 European participants. Common alleles on chromosome Xq23 are strongly associated with reduced total cholesterol, LDL cholesterol, and triglycerides (min P = 8.5 × 10−72), with similar effects for males and females. Chromosome Xq23 lipid-lowering alleles are associated with reduced odds for CHD among 42 ...

Musculoskeletal modeling provides an alternative to in-vivo characteristics that are difficult to directly measure for movements such as running, especially for trunk muscles and joints. The full-body-lumbar-spine (FBLS) model by Raabe and Chaudhari, 2016 is an OpenSim model created for simulations of jogging. The lifting full-body (LFB) model by Beaucage-Gauvreau et al., 2018 is an adaptation of the FBLS created for estimating spinal loads during lifting. PURPOSE: Determine validity of the FBLS and LFB models in simulating pelvis and lumbar spine kinematics during running. METHODS: Inverse Kinematics were executed using experimental data for the FBLS and LFB models. To obtain ...


Automatic Generation And Novel Validation Of Patient-Specific, Anatomically Inclusive Scoliosis Models For Biomechanics-Informed Surgical Planning, Austin Tapp, Michel Audette, James Bennett 2021 Old Dominion University

Automatic Generation And Novel Validation Of Patient-Specific, Anatomically Inclusive Scoliosis Models For Biomechanics-Informed Surgical Planning, Austin Tapp, Michel Audette, James Bennett

College of Engineering & Technology (Batten) Posters

Scoliosis is an abnormal spinal curvature of greater than 10 degrees. Severe scoliotic deformities are addressed with highly invasive procedures: anterior or posterior spinal fusion approaches. This invasiveness is due, in part, to the constraints of current surgical planning, which utilizes computed tomography (CT) scans unable to discern spinal ligaments that are dissected to make the spine sufficiently compliant for correction. If localization of ligaments and soft tissues were achieved pre-operatively, corrective procedures could become safer and more efficient by using finite element (FE) biomechanical simulations to determine decreased incidences of ligament releases. This research aims to achieve ligament localization ...

Clostridioides difficile disproportionally affects the elderly living in nursing homes (NHs). Our objective was to explore the prevalence of C. difficile in NH elders, over time and to determine whether the microbiome or other clinical factors are associated with C. difficile colonization. We collected serial stool samples from NH residents. C. difficile prevalence was determined by quantitative polymerase-chain reaction detection of Toxin genes tcdA and tcdB; microbiome composition was determined by shotgun metagenomic sequencing. We used mixed-effect random forest modeling machine to determine bacterial taxa whose abundance is associated with C. difficile prevalence while controlling for clinical covariates including demographics ...


Evidence-Based Practice: Delaying Infant Bathing, Gabrielle Wadle, Grace Frankland 2021 Murray State University

Evidence-Based Practice: Delaying Infant Bathing, Gabrielle Wadle, Grace Frankland

Scholars Week

A hospital's policy regarding infant bathing is currently not congruent with best nursing practice. The hospital’s current policy is to bathe an infant once they are stable and their rectal temperature is at or above 98.6 °F. Although the infant may become stable within the first 24-hours of birth, the World Health Organization recommends that, “Bathing should be delayed until 24 hours after birth.” (2013, p. 4). Research has been completed to support delaying infant bathing until 24 hours post-delivery, suggesting potential modifications to current policy.
