BACKGROUND: Although surveys and apps are available for women to report urination and bladder symptoms, they do not include their decisions regarding toileting. Real-world factors can interfere with toileting decisions, which may then influence bladder health. This premise lacks data per want of a robust data collection tool.

OBJECTIVE: The Prevention of Lower Urinary Tract Symptoms (PLUS) research consortium engaged a transdisciplinary team to build and test WhereIGo, a mobile data collection app for Android and iOS. The design goal was a comprehensive reporting system for capturing environmental, sociocultural, and physical factors that influence women's decisions for toileting. Aims include …

An Interpretable Machine Learning-Based Cerebrospinal Fluid Proteomics Clock For Predicting Age Reveals Novel Insights Into Brain Aging, Justin Melendez, Yun Ju Sung, Miranda Orr, Andrew Yoo, Suzanne Schindler, Carlos Cruchaga, Randall Bateman

2020-Current year OA Pubs

Machine learning can be used to create "biologic clocks" that predict age. However, organs, tissues, and biofluids may age at different rates from the organism as a whole. We sought to understand how cerebrospinal fluid (CSF) changes with age to inform the development of brain aging-related disease mechanisms and identify potential anti-aging therapeutic targets. Several epigenetic clocks exist based on plasma and neuronal tissues; however, plasma may not reflect brain aging specifically and tissue-based clocks require samples that are difficult to obtain from living participants. To address these problems, we developed a machine learning clock that uses CSF proteomics to …

Age-related vision loss caused by retinal neurodegenerative pathologies is becoming more prevalent in our ageing society. To understand the physiological and molecular impact of ageing on retinal homeostasis, we used the short-lived African turquoise killifish, a model known to naturally develop central nervous system (CNS) ageing hallmarks and vision loss. Bulk and single-cell RNA-sequencing (scRNAseq) of three age groups (6-, 12-, and 18-week-old) identified transcriptional ageing fingerprints in the killifish retina, unveiling pathways also identified in the aged brain, including oxidative stress, gliosis, and inflammageing. These findings were comparable to observations in the ageing mouse retina. Additionally, transcriptional changes in …

OBJECTIVE: Maintaining attention underlies many aspects of cognition and becomes compromised early in neurodegenerative diseases like Alzheimer's disease (AD). The consistency of maintaining attention can be measured with reaction time (RT) variability. Previous work has focused on measuring such fluctuations during in-clinic testing, but recent developments in remote, smartphone-based cognitive assessments can allow one to test if these fluctuations in attention are evident in naturalistic settings and if they are sensitive to traditional clinical and cognitive markers of AD.

METHOD: Three hundred and seventy older adults (aged 75.8 +/- 5.8 years) completed a week of remote daily testing on the …


Assessment Of Gait, Balance, And Falls In Individuals With Neurodegenerative Diseases, Lauren Tueth May 2024

Assessment Of Gait, Balance, And Falls In Individuals With Neurodegenerative Diseases, Lauren Tueth

WUSM Theses and Dissertations – All Programs

Neurodegenerative diseases are a group of disorders that impact the brain and lead to neuronal degeneration. This degeneration causes many different symptoms, which are often grouped into motor, cognitive, and psychiatric domains. Individuals with these disorders can experience symptoms from multiple domains at the same time, but little is known about how these distinct symptoms may impact each other.

In Chapter 2, we explored the intersection of balance and cognitive impairment in individuals with Alzheimer disease (AD). AD is traditionally discussed in the context of the dementia symptoms, but people with AD also experience motor deficits. Falls are a huge …


Exploring Complex Daily Tasks In Preclinical Alzheimer Disease, Audrey A. Keleman May 2024

Exploring Complex Daily Tasks In Preclinical Alzheimer Disease, Audrey A. Keleman

WUSM Theses and Dissertations – All Programs

Alzheimer disease (AD) is a slowly progressive neurodegenerative disorder marked by a gradual decline in cognitive functions and ability to perform daily activities. AD begins with a clinically silent period in which pathological abnormalities accumulate in the brain before cognitive impairments occur (i.e., while individuals remain cognitively normal [CN]). This stage is known as preclinical AD and can last up to two decades. It can be identified by measuring biomarkers of AD using neuroimaging or biofluid techniques. In the United States alone, it is estimated that nearly 46 million individuals are in the preclinical stage of AD and at risk …

Human studies of early brain development have been limited by extant neuroimaging methods. MRI scanners present logistical challenges for imaging young children, while alternative modalities like functional near-infrared spectroscopy have traditionally been limited by image quality due to sparse sampling. In addition, conventional tasks for brain mapping elicit low task engagement, high head motion, and considerable participant attrition in pediatric populations. As a result, typical and atypical developmental trajectories of processes such as language acquisition remain understudied during sensitive periods over the first years of life. We evaluate high-density diffuse optical tomography (HD-DOT) imaging combined with movie stimuli for high …

Calorie Restriction Reduces Biomarkers Of Cellular Senescence In Humans, Zaira Aversa, Susan B Racette, Et Al. Feb 2024

Calorie Restriction Reduces Biomarkers Of Cellular Senescence In Humans, Zaira Aversa, Susan B Racette, Et Al.

2020-Current year OA Pubs

Calorie restriction (CR) with adequate nutrient intake is a potential geroprotective intervention. To advance this concept in humans, we tested the hypothesis that moderate CR in healthy young-to-middle-aged individuals would reduce circulating biomarkers of cellular senescence, a fundamental mechanism of aging and aging-related conditions. Using plasma specimens from the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE™) phase 2 study, we found that CR significantly reduced the concentrations of several senescence biomarkers at 12 and 24 months compared to an ad libitum diet. Using machine learning, changes in biomarker concentrations emerged as important predictors of the change …


Core Requirements Of Frailty Screening In The Emergency Department: An International Delphi Consensus Study, Elizabeth Moloney, Christopher R Carpenter, Et Al. Feb 2024

Core Requirements Of Frailty Screening In The Emergency Department: An International Delphi Consensus Study, Elizabeth Moloney, Christopher R Carpenter, Et Al.

2020-Current year OA Pubs

INTRODUCTION: Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study.

METHODS: A two-round electronic Delphi involving 37 participants from 10 countries was undertaken. Statements were generated from a prior systematic review examining frailty screening instruments in ED (logistic, psychometric and clinimetric properties). Reflexive thematic analysis generated a list of 56 statements …

Greater Socioenvironmental Risk Factors And Higher Chronic Pain Stage Are Associated With Thinner Bilateral Temporal Lobes, Lisa H Antoine, Burel R Goodin, Et Al.

2020-Current year OA Pubs

INTRODUCTION: Previous research indicates ethnic/race group differences in pain and neurodegenerative diseases. Accounting for socioenvironmental factors reduces ethnic/race group differences in clinical and experimental pain. In the current study sample, we previously reported that in individuals with knee pain, ethnic/race group differences were observed in bilateral temporal lobe thickness, areas of the brain associated with risk for Alzheimer's disease, and related dementias. The purpose of the study was to determine if socioenvironmental factors reduce or account for previously observed ethnic/race group differences and explore if a combined effect of socioenvironmental risk and chronic pain severity on temporal lobe cortices is …


Association Between Microbiome And The Development Of Adverse Posttraumatic Neuropsychiatric Sequelae After Traumatic Stress Exposure, Abigail L Zeamer, Stacey L House, Et Al. Nov 2023

Association Between Microbiome And The Development Of Adverse Posttraumatic Neuropsychiatric Sequelae After Traumatic Stress Exposure, Abigail L Zeamer, Stacey L House, Et Al.

2020-Current year OA Pubs

Patients exposed to trauma often experience high rates of adverse post-traumatic neuropsychiatric sequelae (APNS). The biological mechanisms promoting APNS are currently unknown, but the microbiota-gut-brain axis offers an avenue to understanding mechanisms as well as possibilities for intervention. Microbiome composition after trauma exposure has been poorly examined regarding neuropsychiatric outcomes. We aimed to determine whether the gut microbiomes of trauma-exposed emergency department patients who develop APNS have dysfunctional gut microbiome profiles and discover potential associated mechanisms. We performed metagenomic analysis on stool samples (n = 51) from a subset of adults enrolled in the Advancing Understanding of RecOvery afteR traumA …


Management Of Constipation In Hospitalized Patients, Gregory S Sayuk, Qi T Yu, Corey Shy Sep 2023

Management Of Constipation In Hospitalized Patients, Gregory S Sayuk, Qi T Yu, Corey Shy

2020-Current year OA Pubs

Constipation is frequently encountered in hospital settings and can have potentially serious consequences yet is often underrecognized and undertreated. Opioid-induced constipation is a common cause of constipation in hospitalized patients. Opioids induce constipation through agonistic effects on enteric µ-opioid receptors. This review aims to provide insight on the identification and management of constipation in inpatient settings, with a particular focus on opioid-induced constipation. Constipation assessment should be routinely initiated at hospital admission and can be facilitated by thorough symptom assessments; relevant patient history, including recent medication use; physical examination; and patient assessment tools developed to evaluate the impact of constipation. …

Alzheimer's disease (AD) pathology develops many years before the onset of cognitive symptoms. Two pathological processes-aggregation of the amyloid-β (Aβ) peptide into plaques and the microtubule protein tau into neurofibrillary tangles (NFTs)-are hallmarks of the disease. However, other pathological brain processes are thought to be key disease mediators of Aβ plaque and NFT pathology. How these additional pathologies evolve over the course of the disease is currently unknown. Here we show that proteomic measurements in autosomal dominant AD cerebrospinal fluid (CSF) linked to brain protein coexpression can be used to characterize the evolution of AD pathology over a timescale spanning …

Age-Related Alterations In Meningeal Immunity Drive Impaired Cns Lymphatic Drainage, Justin Rustenhoven, Georgios Pavlou, Steffen E Storck, Taitea Dykstra, Siling Du, Zhengpeng Wan, Daniel Quintero, Joshua P Scallan, Igor Smirnov, Roger D Kamm, Jonathan Kipnis

2020-Current year OA Pubs

The meningeal lymphatic network enables the drainage of cerebrospinal fluid (CSF) and facilitates the removal of central nervous system (CNS) waste. During aging and in Alzheimer's disease, impaired meningeal lymphatic drainage promotes the buildup of toxic misfolded proteins in the CNS. Reversing this age-related dysfunction represents a promising strategy to augment CNS waste clearance; however, the mechanisms underlying this decline remain elusive. Here, we demonstrate that age-related alterations in meningeal immunity underlie this lymphatic impairment. Single-cell RNA sequencing of meningeal lymphatic endothelial cells from aged mice revealed their response to IFNγ, which was increased in the aged meninges due to …

Mechanically Manipulating Glymphatic Transport By Ultrasound Combined With Microbubbles, Dezhuang Ye, Si Chen, Yajie Liu, Charlotte Weixel, Zhongtao Hu, Jinyun Yuan, Hong Chen

2020-Current year OA Pubs

The glymphatic system is a perivascular fluid transport system for waste clearance. Glymphatic transport is believed to be driven by the perivascular pumping effect created by the pulsation of the arterial wall caused by the cardiac cycle. Ultrasound sonication of circulating microbubbles (MBs) in the cerebral vasculature induces volumetric expansion and contraction of MBs that push and pull on the vessel wall to generate a MB pumping effect. The objective of this study was to evaluate whether glymphatic transport can be mechanically manipulated by focused ultrasound (FUS) sonication of MBs. The glymphatic pathway in intact mouse brains was studied using …

Sleep-Wake Patterns Are Altered With Age, Prdm13 Signaling In The Dmh, And Diet Restriction In Mice, Shogo Tsuji, Cynthia S Brace, Nicholas Rensing, Michael Wong, Shin-Ichiro Imai, Et Al.

2020-Current year OA Pubs

Old animals display significant alterations in sleep-wake patterns such as increases in sleep fragmentation and sleep propensity. Here, we demonstrated that PR-domain containing protein 13 (Prdm13)+ neurons in the dorsomedial hypothalamus (DMH) are activated during sleep deprivation (SD) in young mice but not in old mice. Chemogenetic inhibition of Prdm13+ neurons in the DMH in young mice promotes increase in sleep attempts during SD, suggesting its involvement in sleep control. Furthermore, DMH-specific

Baseline Characteristics Of The North American Prodromal Synucleinopathy Cohort, Jonathan E Elliott, Jennifer Mcleland, Susan R Criswell, Yo-El S Ju, Et Al.

2020-Current year OA Pubs

OBJECTIVE: Rapid eye movement (REM) sleep behavior disorder (RBD) is widely considered a prodromal synucleinopathy, as most with RBD develop overt synucleinopathy within ~10 years. Accordingly, RBD offers an opportunity to test potential treatments at the earliest stages of synucleinopathy. The North American Prodromal Synucleinopathy (NAPS) Consortium has created a multisite RBD participant, primarily clinic-based cohort to better understand characteristics at diagnosis, and in future work, identify predictors of phenoconversion, develop synucleinopathy biomarkers, and enable early stage clinical trial enrollment.

METHODS: Participants ≥18 years of age with overnight polysomnogram-confirmed RBD without Parkinson's disease, dementia, multiple system atrophy, or narcolepsy were …
