Introduction

This study assessed the hypothesis that circulating human amylin (amyloid‐forming) cross‐seeds with amyloid beta (Aβ) in early Alzheimer's disease (AD).

Methods

Evidence of amylin‐AD pathology interaction was tested in brains of 31 familial AD mutation carriers and 20 cognitively unaffected individuals, in cerebrospinal fluid (CSF) (98 diseased and 117 control samples) and in genetic databases. For functional testing, we genetically manipulated amylin secretion in APP/PS1 and non‐APP/PS1 rats.

Results

Amylin‐Aβ cross‐seeding was identified in AD brains. High CSF amylin levels were associated with decreased CSF Aβ42 concentrations. AD risk and amylin gene are not correlated. Suppressed amylin secretion protected …

Functional Constipation Induces Bladder Overactivity Associated With Upregulations Of Htr2 And Trpv2 Pathways., Nao Iguchi, Alonso Carrasco, Alison X. Xie, Ricardo H. Pineda, Anna P. Malykhina, Duncan T. Wilcox

Manuscripts, Articles, Book Chapters and Other Papers

Bladder and bowel dysfunction (BBD) is a common yet underdiagnosed paediatric entity that describes lower urinary tract symptoms (LUTS) accompanied by abnormal bowel patterns manifested as constipation and/or encopresis. LUTS usually manifest as urgency, urinary frequency, incontinence, and urinary tract infections (UTI). Despite increasing recognition of BBD as a risk factor for long-term urinary tract problems including recurrent UTI, vesicoureteral reflux, and renal scarring, the mechanisms underlying BBD have been unclear, and treatment remains empirical. We investigated how constipation affects the lower urinary tract function using a juvenile murine model of functional constipation. Following four days of functional constipation, animals …

A Semiparametric Modeling Approach For Analyzing Clinical Biomarkers Restricted To Limits Of Detection, Sandipan Dutta, Susan Halabi

Mathematics & Statistics Faculty Publications

Before biomarkers can be used in clinical trials or patients' management, the laboratory assays that measure their levels have to go through development and analytical validation. One of the most critical performance metrics for validation of any assay is related to the minimum amount of values that can be detected and any value below this limit is referred to as below the limit of detection (LOD). Most of the existing approaches that model such biomarkers, restricted by LOD, are parametric in nature. These parametric models, however, heavily depend on the distributional assumptions, and can result in loss of precision under …

Using The Memorial Sloan Kettering Frailty Index To Identify Patients At High Risk For Postoperative Intensive Care Unit Admission, Specialized Advanced Care Unit Admission, And 30-Day Readmission, Timothy J. Donoghue

Theses and Dissertations

Frailty is roughly defined as an accumulation of physiological, emotional, cognitive, and social deficits that impair a person’s response to stressful events. A frailty diagnosis has been associated with poor outcomes following surgical procedures. Cancer surgical patients aged 65 or older represent a vulnerable population susceptible to being frail and the potential associated complications that can accompany frailty. Measuring frailty is an objective risk assessment that identifies increased risk better than age or American Society of Anesthesiologists Physical Status (ASA-PS) score such that frailty can independently predict poor surgical outcomes.

Frailty is not specifically a result of having cancer, disability, …

Is There A Role For Ct Pan-Scans In The Initial Work-Up Of Fragility Fracture Patients?, Eric Lepkowsky, Trevor Simcox, Hunter Rogoff, Shahidul Islam, Omid Barzideh

Stony Brook Orthopaedic and Musculoskeletal Journal

Background: CT pan-scans have become increasingly commonplace as part of the initial diagnostic work-up for patients sustaining traumatic injuries. They have proven effective in improving diagnostic accuracy in those with high energy mechanisms of injury. However, the utility of pan-scans in the geriatric population sustaining low energy traumatic injuries remains unproven. There is no study that assesses the usefulness of CT pan-scans in patients who sustain injuries related to osteoporosis, also known as fragility fractures.

Methods: A retrospective review was conducted of patients who sustained a fragility fracture at a Level 1 trauma center over a 15-month period. Patients underwent …

Hospice Response To Covid-19: Promoting Sustainable Inclusion Strategies For Racial And Ethnic Minorities, M. Courtney Hughes, Erin Vernon

Faculty Articles, Papers, and Other Scholarship

There is a disproportionate burden of illness and death among racial/ethnic minorities related to COVID-19. The importance of reaching groups suffering the most with resources such as advance directive guidance, telehealth, and culturally sensitive education materials is vital to providing quality, inclusive care. A crisis presents an opportunity to unite and problem-solve to help avoid the dire consequences facing inaction. In this way, inclusive responses by hospices, social workers, other community partners during the COVID-19 pandemic can help reach and alleviate the pain of those groups most afflicted. We offer hospice inclusion strategies that align with general pandemic response trends …

Why End-Of-Life Discussion Matters: A Systematic Literature Review, Emily Grandson

All Graduate Theses, Dissertations, and Other Capstone Projects

End-of-life (EOL) discussions are a challenging yet vital topic of conversation in intensive care units (ICU) between healthcare providers, patients, and their families. There is great disparity in where, when, and how EOL discussions take place, but the consequences of neglecting their importance can be devastating physically, psychologically, and financially for all parties involved. Multiple inadequacies in the EOL discussion process have not only contributed to a personal and societal financial burden but an unacceptable quality of death for many ICU patients. A literature review was performed to determine what practice and policy changes could be made to improve EOL …

Reducing Polypharmacy In Older Adults At End Of Life: The Outcome On Quality Of Life, Melissa Jenson

How Does Direct Volunteering Affect The Onset Of Alzheimer’S Dementia In Elderly Patients With Preexisting Cardiac Comorbidities?, Sneha R. Gade

UROP Posters

Alzheimer's Dementia is a disease that affects memory, thinking, and behavior. The Alzheimer's Association reported Alzheimer's as the sixth-leading cause of death in the United States, and a cure does not exist. Donepezil, a cholinesterase inhibitor drug, is frequently prescribed to treat Alzheimer's disease. Still, patients must continuously take the medication for years to receive any measurable improvement in quality of life after developing Alzheimer's Dementia. Further, research shows prolonged use of Donepezil can lead to other health problems, such as QTc prolongation, for cardiac disease patients. Therefore, the effectiveness of non-drug interventions, such as volunteering to prevent the disease's …

How Do Red Blood Cells Die?, Perumal Thiagarajan, Charles J Parker, Josef T Prchal

Faculty, Staff and Students Publications

Normal human red blood cells have an average life span of about 120 days in the circulation after which they are engulfed by macrophages. This is an extremely efficient process as macrophages phagocytose about 5 million erythrocytes every second without any significant release of hemoglobin in the circulation. Despite large number of investigations, the precise molecular mechanism by which macrophages recognize senescent red blood cells for clearance remains elusive. Red cells undergo several physicochemical changes as they age in the circulation. Several of these changes have been proposed as a recognition tag for macrophages. Most prevalent hypotheses for red cell …

Low Serum Irisin As A Risk Factor Of Sarcopenia In Elderly, I Gust Putu Suka Aryana, I.B. Putrawan, Ni Ketut Rai Purnami, R.A. Tuty Kuswardhani, I Nyoman Astika, Ketut Suastika, I Putu Gede Adiatmika, I Made Jawi, I Nyoman Wande

Jurnal Penyakit Dalam Indonesia

Introduction. Sarcopenia is a condition characterized by a decrease in muscle mass accompanied by a decrease in strength and/or function. Sarcopenia is closely related to the aging process, but the mechanism of its occurrence is still not fully understood. Skeletal muscle is the largest organ in the human body, so the myokine produced through muscle contraction opens a new paradigm regarding the central role of muscles in regulating metabolism and other organ functions. One of the myokines that are currently found to affect physical activity is Irisin. This study aims to determine the role of low Irisin levels in serum …

Purpuric Lesion In A Patient With Leprosy: Was It A Lucio’S Phenomenon Or An Epiphenomenon?, Sri Linuwih Menaldi, Melani Marissa, Inadia Putri Chairista, Henry W. Lim, Rahadi Rihatmadja

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Lucio’s phenomenon (LP) is a severe necrotizing cutaneous reaction that occurs in patients with Lucio’s leprosy. The exact pathomechanism is not fully understood, but typically abundant acid-fast bacilli in the walls of blood vessels point to direct perturbation of blood supply to the epidermis. We report a case of LP where epidermal necrosis occurred in the absence of vascular invasion by mycobacteria, raising the question whether this was an epiphenomenon or a true LP.

Case Illustration: A 34-year-old male was referred for an episodic swelling of his hands and feet that persisted for two years. There were …

Revisiting The Role Of Physicians In Assisted Living And Residential Care Settings, Sarah Dys, Lindsey Smith, Ozcan Tunalilar, Paula C. Carder

Institute on Aging Publications

As the United States population ages, a higher share of adults is likely to use long-term services and supports. This change increases physicians’ need for information about assisted living and residential care (AL/RC) settings, which provide supportive care and housing to older adults. Unlike skilled nursing facilities, states regulate AL/RC settings through varying licensure requirements enforced by state agencies, resulting in differences in the availability of medical and nursing services. Where some settings provide limited skilled nursing care, in others, residents rely on resident care coordinators, or their own physicians to oversee chronic conditions, medications, and treatments. The following narrative …

Evaluation Of Aging And Genetic Mutation Variants On Tauopathy, Amber M. Tetlow

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) is characterized by amyloid β plaques and neurofibrillary tau tangles (NFTs). While research has demonstrated amyloid pathology occurs prior to tau pathology, or tauopathy, tau has proven to be more toxic. Tauopathy is associated with cognitive declines and neurodegeneration. These findings have highlighted the importance of further understanding tauopathy. In the progression of tauopathy, there is an observable immune response that can be measured by glial cells such as microglia. Activated microglia are known to exacerbate tauopathy rather than reducing the pathology. Research has indicated that with increased age there is an increased risk for AD-related tauopathy …

Neutrophil-To-Lymphocyte Ratio: A Biomarker To Monitor The Immune Status Of Astronauts, Amber M. Paul, Siddhita D. Mhatre, Egle Cekanaviciute, Ann-Sofie Schreurs, Candice G.T. Tahimic, Ruth K. Globus, Sulekha Anand, Brian E. Crucian, Sharmila Bhattacharya

Publications

A comprehensive understanding of spaceflight factors involved in immune dysfunction and the evaluation of biomarkers to assess in-flight astronaut health are essential goals for NASA. An elevated neutrophil-to-lymphocyte ratio (NLR) is a potential biomarker candidate, as leukocyte differentials are altered during spaceflight. In the reduced gravity environment of space, rodents and astronauts displayed elevated NLR and granulocyte-to-lymphocyte ratios (GLR), respectively. To simulate microgravity using two well-established ground-based models, we cultured human whole blood-leukocytes in high-aspect rotating wall vessels (HARV-RWV) and used hindlimb unloaded (HU) mice. Both HARV-RWV simulation of leukocytes and HU-exposed mice showed elevated NLR profiles comparable to spaceflight …
