Objective: To investigate maternal physiologic and infant feeding factors associated with infant overweight and/or obesity in a sample of Salvadoran mother-infant dyads. Methods: A …


The Lived Experience Of Recovery Following Transoral Robotic Surgery (Tors) For Head And Neck Cancer, Katharine Mahalik May 2019

The Lived Experience Of Recovery Following Transoral Robotic Surgery (Tors) For Head And Neck Cancer, Katharine Mahalik

Electronic Theses and Dissertations

Abstract

Ongoing advances in minimally invasive surgical techniques, such as transoral robotic surgery (TORS), has enabled select patients with head and neck cancer to receive treatment that results in less disfigurement and dysfunction compared with traditional approaches. While TORS research has focused mainly on functional surgical outcomes, a need exists to understand recovery following TORS from the patient perspective. A hermeneutic phenomenological approach was used to recruit patients who had recently undergone TORS at a major academic health system in northeastern US. Data were collected using audio-recorded telephone interviews and field notes and analyzed concurrently. Participants included 17 HNCS (12 …

Modeling And Prediction Of Amorphous Solid Dispersion Formation Using A Molecular Descriptor, Kevin Deboyace May 2019

Modeling And Prediction Of Amorphous Solid Dispersion Formation Using A Molecular Descriptor, Kevin Deboyace

Electronic Theses and Dissertations

Poor aqueous solubility of an active pharmaceutical ingredient (API) is a significant hurdle during drug development. Delivering a drug in its amorphous solid-state is a potential method to overcome this issue, since the amorphous form has increased apparent aqueous solubility. However, the amorphous state is only metastable, and is thermodynamically driven to recrystallize. As a result, pure amorphous drugs are seldom used in marketed products. Intimately mixing a drug in its amorphous form with a polymer, known as an amorphous solid dispersion (ASD), has the potential to significantly extend the physical stability of the amorphous form, while maintaining the benefit …


Public Health Policy: An Ethical Analysis Of Quarantine, Dina Alqahtani May 2019

Public Health Policy: An Ethical Analysis Of Quarantine, Dina Alqahtani

Electronic Theses and Dissertations

As a public health measure quarantine has both historical and contemporary significance both in the United States and abroad. On the surface it represents a low-cost, low-tech way in which the spread of disease can be mitigated as its core requirement is that those who may have been exposed to an infectious agent are kept away from those who have not been exposed to that agent for enough time to determine whether or not infection has been spread. This has been utilized for centuries with both limited questions and scattered, inconsistent, or impossible to achieve oversight and goals. In understanding …


An Ethical Analysis Of Reproductive Justice In The Context Of The Egenics Movement In The United States, Bernetta Welch May 2019

An Ethical Analysis Of Reproductive Justice In The Context Of The Egenics Movement In The United States, Bernetta Welch

Electronic Theses and Dissertations

The history of forced sterilization and the American cultural agreement with this practice robbed women of color of control of their own bodies, destinies, and communities. Negative eugenics as genetic proof of low intelligence, low possibility, and low productivity fed the system of compulsory sterilization even though the science proved faulty and incorrect. As advances in medical technology and genetic science increases, eugenics is making a return into the American psyche. Vulnerable populations which include women of color make reproduction and the subsequent control of their bodies vulnerable once again.

The Reproductive Justice Movement is a collaboration of organized women …

The Ethical Challenge Of Conflicts Of Interest In Healthcare, Fahad Alhazmi May 2019

The Ethical Challenge Of Conflicts Of Interest In Healthcare, Fahad Alhazmi

Electronic Theses and Dissertations

Conflicts of interest are prevalent across all walks of society, and unfortunately, the healthcare industry is not immune to these impediments. Conflicts of interest arise when the objective of upholding a patients’ interest collide with the physicians’ secondary goals and is mostly but not always related to monetary gain.

To avoid conflict of interest, it is advisable for medical practitioners to weigh the pros and cons that their actions would inflict. Medical practices whose benefits outweigh the associated risks are ethically upright hence avoid conflict of interest.

Each section proposes solutions for the conflicts of interest encountered at the disparate …

Probiotic Use In Trauma Patients: A Pathway To Determining The Standard Of Care To Improve Outcomes, Heather Vitko

Electronic Theses and Dissertations

The gut microbiome consists of normally non-pathogenic bacteria, viruses, and fungi. These friendly microbes serve to maintain GI barrier function and integrity, play a role in host nutrient and drug metabolism, immunomodulation, and prevent pathogenic bacteria from colonizing or causing disease. The importance of a healthy microbiome for the overall health of the host is just recently being appreciated within the medical and science communities. Disruption of the microbiome places one at greater risk for illness and infection. Patients who suffer a traumatic injury are among those at highest risk for complications associated with microbial imbalance, or dysbiosis. In addition …

Characterization Of G-Protein Coupled Receptors In Pain, Depression And Anxiety, Neil Lax Dec 2018

Characterization Of G-Protein Coupled Receptors In Pain, Depression And Anxiety, Neil Lax

Electronic Theses and Dissertations

Chronic pain and major depressive disorder are widespread conditions in the world. Interestingly, these conditions often occur comorbidly, with each individual disease amplifying the symptoms of the other. A significant amount of preclinical research in pain and depression focuses on G-protein coupled receptors (GPCRs), implying that GPCRs may be useful in treating this comorbidity. Our efforts have sought to characterize several poorly understood GPCRs, including the serotonin receptor subtypes 2C and 7 (5-HT2CR and 5-HT7R) and metabotropic glutamate receptor 5 (mGluR5), along with more well-known GPCRs such as the mu opioid receptor (MOR), and the role that they play in …

The Influence Of Age, Gender, And Thiol Repletion In An In Vivo Model Of Lewy Body Disorders, Daniel Mason Dec 2018

The Influence Of Age, Gender, And Thiol Repletion In An In Vivo Model Of Lewy Body Disorders, Daniel Mason

Electronic Theses and Dissertations

Lewy body disorders are a family of neurological brain disorders associated with olfactory, motor, and cognitive deficits and are collectively defined as α-synucleinopathies, as they are characterized by hallmark “Lewy bodies” composed of aggregated, fibrillar α-synuclein. It is not certain but often posited that fibrillar α-synuclein seeds the progressive, self-propagating spread of Lewy pathology through neuroanatomical circuitry. Furthermore, the site of disease induction is still debated. In Aim I, we developed a novel protocol for generating reproducible and robust α-synucleinopathy in the limbic temporal lobe following infusions of preformed α-synuclein iv fibrils into the mouse olfactory bulb, which is frequently …


Ultrasound Visual Biofeedback And Accent Modification: Effects On Consonant And Vowel Accuracy For Mandarin English Language Learners, Courtney Armstrong Aug 2018

Ultrasound Visual Biofeedback And Accent Modification: Effects On Consonant And Vowel Accuracy For Mandarin English Language Learners, Courtney Armstrong

Electronic Theses and Dissertations

The number of individuals in the United States who speak languages other than English continues to increase. With the increase of language diversity comes a potential rise in communication challenges for those who speak with non-mainstream American English accents as English language learners. A portion of these individuals may elect to seek accent modification services, perhaps due to decreased intelligibility or communication breakdowns. Thus, speech-language pathologists must research and provide effective techniques to enhance intelligibility of all American English speakers for optimal communication. Few approaches employ a variety of treatment methods to improve speech sound accuracy, naturalness and intelligibility to …

The Effect Of The Movie Time Social Learning Method On The Emotional Inferencing Skills In An Adult With Autism Spectrum Disorder, Jenna Reade Aug 2018

The Effect Of The Movie Time Social Learning Method On The Emotional Inferencing Skills In An Adult With Autism Spectrum Disorder, Jenna Reade

Electronic Theses and Dissertations

Individuals with autism spectrum disorder (ASD) have difficulty finding employment and maintaining social relationships. Professional and personal interactions require individuals to make inferences, or read between the lines. Inferencing is a challenge for individuals with ASD because it requires complex information processing. More specifically, it involves the integration of cognitive and linguistic information. There is a lack of research using complex stimuli to treat inferencing. An A-B-A-B design with one adult with ASD was used to examine the effectiveness of a movie-based method, Movie Time Social Learning(Vagin, 2012), on improving the emotional inferencing skills of one young adult with …


Self-Assembling Bioaffinity Hydrogels For Localized Antibody Delivery, Wen Liu Aug 2018

Self-Assembling Bioaffinity Hydrogels For Localized Antibody Delivery, Wen Liu

Electronic Theses and Dissertations

The scope of illnesses that are being treated using monoclonal antibodies (mAbs) has been expanding from cancers to autoimmune diseases due to their high specificity to their molecular target. Because many of the new mAbs are aimed to modulate the immune system, an emerging concern is that patients with chronic illnesses are subjected to immune-related Adverse Events (irAEs). Loss of immunological tolerance to self-antigens or increased susceptibility to infections have been documented in some mAb treatments. Localized sustained release of mAb at disease sites might mitigate the risk of such toxicities. Antibody drugs are formulated typically for parenteral delivery because …


The Myth Of Promiscuity: Examining Black Male Sexual Narratives And Sexual Identity, Seth Young Aug 2018

The Myth Of Promiscuity: Examining Black Male Sexual Narratives And Sexual Identity, Seth Young

Electronic Theses and Dissertations

Black masculinity and sexuality are common topics across areas of philosophy, psychology, cultural studies and others. Yet, these topics are dedicated to the racial narrative of hypersexual Black male, the sexual objectification of Black men, and their presumed promiscuity. While such topics are important, there is little qualitative research that looks at the complexity and emotionality of African American men’s sexual experiences. Using the theoretical research on black masculinity and sexuality as its backdrop, this dissertation explores how heterosexual, African American men experience their sexuality. The study incorporates narrative inquiry and in-depth, semi-structured interviews to gather stories of five African …


Macromolecule Loading On Plga Particles Through Surface Adsorption, Yiwei Wang Aug 2018

Macromolecule Loading On Plga Particles Through Surface Adsorption, Yiwei Wang

Electronic Theses and Dissertations

The advent of biotherapeutics have impacted the ways in which diseases are treated. In many instances development of recombinant proteins and oligonucleotides into therapeutics are slowed by poor stability of the candidate drugs. Progress has been made in using polymeric particles as carriers of macromolecule drugs. Historically the method is to encapsulate biological drugs into spherical polymeric matrices. Owing to its biocompatible and biodegradable nature, poly (d,l-lactic-co-glycolic acid) (PLGA) has been used extensively in formulating biological drugs into nano- and micro-sized particles. The development of PLGA biologic formulations, however, has been hampered by matrix acidification; the hydrolysis of the polymer …
