Assessment And Intervention For Health Behavior Change In Primary Care Across The Lifespan: A Guide For Residents In Primary Care Specialties, Stacy A. Ogbeide, Alexis Ramos, Bridget Murphy, Angel Ogbeide
HCA Healthcare Journal of Medicine
More than 45% of Americans have at least 1 chronic disease, with chronic disease also being a leading cause of death in the United States. In primary care settings, about 75% of visits are for management of multiple chronic diseases. Due to the increasing medical complexity of patients who present to primary care, these numbers make it more challenging for Primary Care Clinicians (PCCs) to manage these conditions alone and point to the need for innovative solutions to chronic disease care. One evidence-based innovation is team-based care to improve the treatment of these conditions. Clinicians such as clinical pharmacists, registered …
The Effect Of The Lee Silverman Voice Treatment (Lsvt) Big Method Based On Occupation On Older Adult Functional Mobility Balance, Muhammad Luthfi, Kharisma Nur Idalasari
The Effect Of The Lee Silverman Voice Treatment (Lsvt) Big Method Based On Occupation On Older Adult Functional Mobility Balance, Muhammad Luthfi, Kharisma Nur Idalasari
Jurnal Fisioterapi Terapan Indonesia
Balance impairment is one of the major problems commonly experienced by older adults as a result of degenerative processes, leading to an increased risk of falls. Falls may cause fear of recurrent falling, reduced physical activity, loss of physical capability, and may eventually result in disability and psychological consequences such as depression. Structured, occupation-based physical activity has been shown to provide various benefits for older adults, including improving physical function, slowing functional decline associated with degenerative processes, reducing fall risk, and enhancing postural control. This study aimed to analyze the effect of the occupation-based Lee Silverman Voice Treatment (LSVT) BIG …
The Geography Of Faces, Faith Abraham
The Geography Of Faces, Faith Abraham
be Still
The Geography of Faces takes its title from the idea that a face, seen across decades, becomes a kind of landscape—something you learn to read not at a glance but through accumulated return visits. For Dr. Vasquez, an older physician who has seen so much, her patients' faces are the territory she has spent a lifetime learning to navigate.
The patients are chosen to represent different dimensions of that longevity. They show affection built on years of small battles, continuity across a family, autonomy that is respected. Together, these patients make the case that primary care is less about problems …

Quality Improvement (Qi) Project Aimed At Reducing Unnecessary Antibiotic Usage Among Older Adult Patients By Addressing Inappropriate Antibiotic Prescribing In Primary And Long-Term Care Settings, Pamela M. Thomas
Seton Hall University Dissertations and Theses (ETDs)
Antibiotic overuse among older adults remains a significant patient safety and public health concern. Recent national data indicate that approximately 30%–50% of outpatient antibiotic prescriptions may be unnecessary, particularly for viral or self-limiting conditions (Chua et al., 2021). Antimicrobial resistance has been associated with more than 1.27 million deaths globally (Murray et al., 2022). This quality improvement project evaluated a multifaceted antimicrobial stewardship intervention in primary and long-term care settings. Baseline review of 167 antibiotic cases revealed 37.1% were inappropriate or questionable, and 28.7% lacked adequate diagnostic documentation. The intervention incorporated provider education, electronic health record decision-support tools, audit and …

UNLV Theses, Dissertations, Professional Papers, and Capstones
Parkinson’s disease (PD) is characterized by a wide range of non-motor symptoms that often affect the quality of life of persons with Parkinson’s disease (PwPD) even more profoundly than the motor symptoms typically associated with the condition. These non-motor symptoms include olfactory and gastrointestinal dysfunction, cognitive impairments, sleep disturbances, and psychological and social concerns. Psychosocial concerns include the mental, emotional, and social impact of PD on an individual’s functioning and, overall well-being. They reflect the interplay between symptoms of the disease, psychological development and functioning, personal relationships, and environmental factors. Mental health and psychosocial concerns such as depression, anxiety, fear …
Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam
Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam
UNLV Theses, Dissertations, Professional Papers, and Capstones
This secondary analysis study evaluated the effectiveness of Cognitive Stimulation Therapy (CST) on quality of life (QoL), depressive symptoms, and cognitive function in 108 community-dwelling older adults with cognitive impairments, including dementia. Outcomes involved Quality of Life (QoL) measured by the Quality of Life in Alzheimer’s Disease (QoL-AD), symptoms of depression by the Cornell Scale for Depression in Dementia (CSDD), and cognitive function using the Saint Louis University Mental Status (SLUMS). After the CST, significant improvements were observed in QoL (p = .004), depressive symptoms (p = .002), and cognitive function (p < .001), with small effect sizes. Additionally, a significant interaction between sex and dementia diagnosis status was found in predicting cognitive changes, suggesting that the relationship between dementia diagnosis and cognitive improvement differs by sex. No between-group differences were found for QoL or depression. Findings support CST as a multidimensional, non-pharmacological intervention that improves cognitive, psychological, and social outcomes. Although effects were small, consistent improvements are clinically meaningful given the progressive nature of dementia. This study extends existing literature by demonstrating CST’s effectiveness in a community-based setting and reinforces its alignment with occupational therapy’s emphasis on participation and holistic care. Results highlight the need for early intervention and expanded access to CST programs to enhance quality of life in this population.

A Case Of Successful Survival In A High-Risk Elderly Patient With Copd After Endotracheal Intubation, Julia Cueto Oms-Ii
Rowan-Virtua Research Day
Exacerbations of chronic obstructive pulmonary disease (COPD) leading to acute respiratory failure (ARF) is one of the major causes of mortality worldwide, thus typically having poor outcomes. Risk factors such as the need for invasive mechanical ventilation (IMV), severity of disease, comorbidities, and increased age are predictors of increased mortality rates in COPD patients. Noninvasive ventilation (NIV), like bilevel positive airway pressure (BiPAP) or high flow nasal cannula (HFNC), is the initial standard of care for acute exacerbations of COPD. However, longer periods of NIV and failure of NIV therapy can lead to delayed endotracheal intubation and higher mortality rates. …

Rowan-Virtua Research Day
Older adults (≥65 years) are at increased risk for postoperative cognitive impairment, including postoperative delirium (POD) and postoperative cognitive dysfunction (POCD), which contribute to prolonged recovery, increased morbidity, and mortality. Preventive strategies include pharmacological interventions and non-pharmacological approaches such as cognitive training; however, these approaches are typically studied in isolation. The purpose of this literature review was to compare the effectiveness of perioperative pharmacological and non-pharmacological interventions in reducing postoperative cognitive impairment in elderly surgical patients. A review of six studies, including randomized controlled trials and cohort studies, was conducted in patients undergoing cardiac, spinal, and noncardiac surgeries. Cognitive outcomes, …

ATU Theses and Dissertations 2021 - Present
The persistent nursing shortage across the United States, particularly in Long-Term Care (LTC) settings, has complicated the healthcare system’s ability to meet the needs of an aging population. While existing research often examines progression from Licensed Practical Nurse (LPN) to Registered Nurse (RN), limited research explores factors influencing progression from entry-level LTC healthcare workers to Practical Nursing (PN) licensure. This quantitative descriptive study examined the barriers and supporting factors influencing advancement toward PN licensure for Medication Assistants-Certified (MA-Cs) in Arkansas LTC facilities. A convenience sample of N=100 participated in the study. Results indicated that financial and structural barriers often …

Transcription factor EB (TFEB) is a master regulator of lysosomal biogenesis and cellular clearance pathways. TFEB activity is tightly controlled by multiple post-translational mechanisms, but the exact molecular mechanism controlling its stability has remained elusive. Here, we identify the IκB kinase (IKK) complex as a key regulator of TFEB protein stability through a phosphorylation-ubiquitination cascade. A high-content kinase inhibitor screen reveals that IKK inhibition increases TFEB protein levels, and genetic ablation of IKK components increases TFEB stability, upregulates lysosomal genes, and enhances lysosomal biogenesis and degradative capacity. Mechanistically, we show that IKK phosphorylates TFEB on a cluster of serine residues …

Urinary tract infections (UTIs), primarily caused by uropathogenic Escherichia coli (UPEC), affect millions annually. UPEC gains access to the urinary tract through mucosal reservoirs, including the vaginal tract. With rising antibiotic resistance and frequent recurrence, alternative non-antibiotic strategies like bacteriophage (phage) therapy are gaining attention. We explored the potential of a lytic phage, ΦHP3, as well as a phage cocktail to decolonize UPEC from the urogenital tract using in vitro and in vivo models. Phage demonstrated replication and lytic activity in both bacteriologic medium and simulated vaginal fluid. Pretreatment of human vaginal epithelial cells (VK2/E6E7) and bladder carcinoma cells (HTB-9) …

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive
There is currently a gap in accurate screening and treatment of anxiety in Long-Term Care (LTC) nursing facilities. The question for this quality improvement project was: Will implementing interventions for long-term care residents aged 65 and older improve anxiety screening, non-pharmacological interventions, and mental health referrals by 10% compared to current practices? Interventions to enhance anxiety screening included the Geriatric Anxiety Scale-Long Term Care (GAS-LTC) tool to assess and score anxiety. In addition, a Non-Pharmacological Intervention (Non-PI) tool was created to evaluate interventions performed by facility staff. Referrals to the mental health care provider were submitted if a resident scored …

Comprehensive genomic analysis is essential for advancing our understanding of human genetics and disease. However, short-read sequencing technologies are inherently limited in their ability to resolve highly repetitive, structurally complex, and low-mappability genomic regions, previously coined as “dark” regions. Long-read sequencing technologies, such as PacBio and Oxford Nanopore Technologies (ONT), offer improved resolution of these regions, yet they are not perfect. With the advent of the new Telomere-to-Telomere (T2T) CHM13 reference genome, exploring its effect on dark regions is prudent. In this study, we systematically analyze dark regions across four human genome references—HG19, HG38 (with and without alternate contigs), and …

Alzheimer's disease neuropathological changes (ADNC)—operationalized with semi-quantitative parameters—represent the consensus-based gold standard for diagnostic evaluation of disease severity. Although useful, ADNC diagnostic frameworks have limitations, particularly in advanced disease stages where pathological severity varies widely within a given diagnostic category. Further, some individuals lacking cognitive impairment are inappropriately categorized as having severe ADNC. In this study, quantitative pathology metrics and alternative tissue sampling schemes were integrated with data about premortem cognitive status, in order to derive clinically informed neuropathologic diagnostic thresholds. Specific goals of the current study were to generate data-driven, standardized diagnostic cut-points, with the most severe stages of …

Amyloid-related imaging abnormalities (ARIA) are the principal safety concern limiting anti-amyloid therapies for Alzheimer’s disease, yet their biology remains unclear. Here we show, through multi-omic profiling of peripheral blood from three ARIA+ patients and matched controls, that ARIA is associated with coordinated reprogramming of CD8 + T cells. CD8+ effector memory (TEM) and terminally differentiated (TEMRA) subsets were expanded, clonally enriched, and transcriptionally primed for cytotoxicity and vascular trafficking. Transcription factor inference and metabolomics converged on glycolytic reprogramming favoring short-lived effector function. Ligand-receptor modeling revealed enhanced monocyte-to-T cell signaling through antigen presentation, adhesion, and chemokine axes, while integration with a …

Apolipoprotein E4 (APOE4) is the strongest risk allele associated with the development of late onset Alzheimer’s disease (AD). Across the CNS, astrocytes are the predominant expressor of APOE while also being critical mediators of neuroinflammation and cerebral metabolism. APOE4 has been consistently linked with dysfunctional inflammation and metabolic processes, yet insights into the molecular constituents driving these responses remain unclear. Utilizing complementary approaches across humanized APOE mice and isogenic human iPSC astrocytes, we demonstrate that ApoE4 alters the astrocyte immunometabolic response to pro-inflammatory stimuli. Our findings show that ApoE4-expressing astrocytes acquire distinct transcriptional repertoires at single-cell and spatially-resolved domains, which …

Honors Undergraduate Theses
Older adults, defined as individuals over the age of 65, are a growing population in the United States, with projections estimating this group will reach approximately 80 million persons by 2050. Over 90% of older adults are diagnosed with a chronic condition, which can make it difficult to carry out the activities of daily living. As a result, some older adults reside in assisted living facilities, where dedicated staff provide daily support. However, issues in the delivery of care within these settings, including unmet socialization needs and complications among care staff, may contribute to social isolation. Programs designed to address …

Background: Sleep disturbances elevate brain amyloid-beta (Aβ) levels and represent a modifiable risk factor for Alzheimer’s disease (AD). The orexin/hypocretin system regulates sleep–wake behavior and has emerged as a therapeutic target in AD; however, the effects of FDA-approved dual orexin receptor antagonists (DORAs) on amyloid pathology remain unclear. We compared lemborexant, an FDA-approved DORA, to doxepin, an antihistaminergic sleep medication, on amyloid pathology and microglial responses in PSAPP mice.
Methods: PSAPP mice received lemborexant (10 or 30 mg/kg/day), doxepin (35 mg/kg/day), or vehicle for 6 weeks beginning prior to plaque onset or 4 weeks after established pathology. Sleep was assessed …

Gait stability arises from interactions between physiological, cognitive, and psychological systems, yet these domains are often assessed in isolation. This study examined multisystem predictors of anteroposterior margin of stability during walking (MoSAP) in community-dwelling older adults. Of 340 participants, 143 were retained after data quality screening (105 females; age: 70.8 ± 7.8 years). Participants completed the Physiological Profile Assessment (PPA), cognitive testing using Montreal Cognitive Assessment (MoCA), fear-of-falling evaluations using Modified Falls Efficacy Scale (MFES) and a biomechanical gait assessment during preferred and fast speeds. Participants were stratified into four PPA-based fall-risk groups: low, mild, moderate, and high risk. MoSAP …
