Dual-Task Does Not Increase Slip And Fall Risk In Healthy Young And Older Adults During Walking, Rahul Soangra, Thurmon Lockhart
Dual-Task Does Not Increase Slip And Fall Risk In Healthy Young And Older Adults During Walking, Rahul Soangra, Thurmon Lockhart
Physical Therapy Faculty Articles and Research
Dual-task tests can identify gait characteristics peculiar to fallers and nonfallers. Understanding the relationship between gait performance and dual-task related cognitive-motor interference is important for fall prevention. Dual-task adapted changes in gait instability/variability can adversely affect fall risks. Although implicated, it is unclear if healthy participants’ fall risks aremodified by dual-task walking conditions. Seven healthy young and seven healthy older adults were randomly assigned to normal walking and dual-task walking sessions with a slip perturbation. In the dual-task session, the participants walked and simultaneously counted backwards from a randomly provided number. The results indicate that the gait changes in dual-task …

Anatomy and Cell Biology Publications
Sleep spindlesshort, phasic, oscillatory bursts of activity that characterize non-rapid eye movement sleepare one of the only electrophysiological oscillations identified as a biological marker of human intelligence (e.g., cognitive abilities commonly assessed using intelligence quotient tests). However, spindles are also important for sleep maintenance and are modulated by circadian factors. Thus, the possibility remains that the relationship between spindles and intelligence quotient may be an epiphenomenon of a putative relationship between good quality sleep and cognitive ability or perhaps modulated by circadian factors such as morningness-eveningness tendencies. We sought to ascertain whether spindles are directly or indirectly related to cognitive …

A 36 -year old woman IV drug abuser admitted with Right-Sided Infective Endocarditis (RSIE) as demonstrated by transthoracic echocardiogram. Patient was admitted 8 weeks later with recurrence of symptoms, moreover signs of systemic embolization were noted. Transthoracic and Transesophageal Echocardiograms revealed tricuspid valve vegetation, severe tricuspid regurgitation, left atrial mass, Patent Foramen Ovale (PFO), severely dilated right atrium and prominent Chiari's network. Systemic embolization included brain and Left iliacus abscesses. Patent Foramen ovale is the proposed mechanism leading to extensive systemic embolization in the present case.

Manuscripts, Articles, Book Chapters and Other Papers
Causes of colonic and recto-sigmoid hematomas are multifactorial. Patients can present with a combination of dropping hemoglobin, bowel obstruction and perforation. Computed tomography imaging can provide clues to a diagnosis of intramural hematoma. We present a case of rectal hematoma and a review of current management literature. A 72-year-old male on therapeutic anticoagulation for a pulmonary embolism, was administered an enema resulting in severe abdominal pain unresponsive to blood transfusion. A sigmoid colectomy with end colostomy was performed. Although rare, colonic and recto-sigmoid hematomas should be considered as a possible diagnosis for adults with abdominal pain on anticoagulant therapy.

Patients with heart failure (HF) have diaphragm abnormalities that contribute to disease morbidity and mortality. Studies in animals suggest that reactive oxygen species (ROS) cause diaphragm abnormalities in HF. However, the effects of HF on ROS sources, antioxidant enzymes, and protein oxidation in the diaphragm of humans is unknown. NAD(P)H oxidase, especially the Nox2 isoform, is an important source of ROS in the diaphragm. Our main hypothesis was that diaphragm from patients with HF have heightened Nox2 expression and p47phox phosphorylation (marker of enzyme activation) that is associated with elevated protein oxidation. We collected diaphragm biopsies from patients with …

Anatomy and Neurobiology Publications
Background
Chronic microglia-mediated inflammation and oxidative stress are well-characterized underlying factors in neurodegenerative disease, whereby reactive inflammatory microglia enhance ROS production and impact neuronal integrity. Recently, it has been shown that during chronic inflammation, neuronal integrity is compromised through targeted disruption of the axon initial segment (AIS), the axonal domain critical for action potential initiation. AIS disruption was associated with contact by reactive inflammatory microglia which wrap around the AIS, increasing association with disease progression. While it is clear that chronic microglial inflammation and enhanced ROS production impact neuronal integrity, little is known about how acute microglial inflammation influences AIS …

dbVar houses over 3 million submitted structural variants (SSV) from 120 human studies including copy number variations (CNV), insertions, deletions, inversions, translocations, and complex chromosomal rearrangements. Users can submit multiple SSVs to dbVAR that are presumably identical, but were ascertained by different platforms and samples, to calculate whether the variant is rare or common in the population and allow for cross validation. However, because SSV genomic location reporting can vary – including fuzzy locations where the start and/or end points are not precisely known – analysis, comparison, annotation, and reporting of SSVs across studies can be difficult. This project was …

The epigenomic reader Brd4 is an important drug target for cancers. However, its role in cell differentiation and animal development remains largely unclear. Using two conditional knockout mouse strains and derived cells, we demonstrate that Brd4 controls cell identity gene induction and is essential for adipogenesis and myogenesis. Brd4 co-localizes with lineage-determining transcription factors (LDTFs) on active enhancers during differentiation. LDTFs coordinate with H3K4 mono-methyltransferases MLL3/MLL4 (KMT2C/KMT2D) and H3K27 acetyltransferases CBP/p300 to recruit Brd4 to enhancers activated during differentiation. Brd4 deletion prevents the enrichment of Mediator and RNA polymerase II transcription machinery, but not that of LDTFs, MLL3/MLL4-mediated H3K4me1, and …

Namibia : Hiv As A National Issue, Elisabeth Vlasak
Global Public Health
Namibia is located on the southwestern coast of Africa, bordering Angola, Botswana, Zambia, South Africa, and the Atlantic Ocean. Namibia has a population of 2,265,000, as of 2016. Namibia has many challenges, including food insecurity and malnutrition, access to health services, unequal distribution of wealth, but HIV/AIDS is one of the country’s leading challenges. It is estimated that the overall adult infection rate of HIV/AIDS is 15.4% and it is the leading cause of death in Namibia. Adults ages 18-24 are the most at-risk for the disease. Some of the major risk factors are declining condom use, misinformation, social stigma, …

Prolotherapy: Applications, Mechanism Of Action, Controversy And Evidence, Boris M. Davydov
Physician Assistant Scholarly Project Posters
Merriam-Webster defines prolotherapy (PROLO) as “an alternative therapy for treating musculoskeletal pain that involves injection of irritant substance (as dextrose) into a ligament or tendon to promote the growth of new tissue”. Experimental research and multiple clinical trials have generated evidence suggesting that PROLO is effective at treating a variety of musculoskeletal conditions, including tendinopathies, joint instability and ligament laxity. PROLO may also hold a potential to delay or avoid joint replacement and rotator cuff surgeries. Further research is needed to demonstrate the therapeutic effect of PROLO unequivocally.

Background: Non-human animals often produce different types of vocalisations in negative and positive contexts (i.e. different valence), similar to humans, in which crying is associated with negative emotions and laughter is associated with positive ones. However, some types of vocalisations (e.g. contact calls, human speech) can be produced in both negative and positive contexts, and changes in valence are only accompanied by slight structural differences. Although such acoustically graded signals associated with opposite valence have been highlighted in some species, it is not known if conspecifics discriminate them, and if contagion of emotional valence occurs as a result. We tested …

The Neuropsychology Of Sport And Performance, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty Publications
Neuropsychological theory has been a mainstay for understanding pathology within the brain-behavior context. However, our theories for predicting superior behavior are not as well developed. Sport neuropsychology was developed on the presumption that athletes represent a population in a relatively well-controlled environment for studying brain pathology due to injury. This study of pathology within a high-performance environment has been responsible for identifying the effects of mild traumatic brain injury (mTBI) on individual functioning. Far less attention has been paid to the other end of the performance continuum, and yet, viable brain-behavior hypotheses should hold true across the spectrum of function …

Center for Brain, Biology, and Behavior: Faculty Publications
Objective — The Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to determine cognitive recovery from concussion based on comparing post-injury scores to baseline scores. This model is based on the premise that ImPACT baseline test scores are a valid and reliable measure of optimal cognitive function at baseline. Growing evidence suggests that this premise may not be accurate and a large contributor to invalid and unreliable baseline test scores may be the protocol and environment in which baseline tests are administered. This study examined the effects of a standardized environment and administration …

Objective: Hundreds of scientific publications are produced annually that involve the measurement of cortisol in saliva. Intra- and inter-laboratory variation in salivary cortisol results has the potential to contribute to crossstudy inconsistencies in findings, and the perception that salivary cortisol results are unreliable. This study rigorously estimates sources of measurement variability in the assay of salivary cortisol within and between established international academic-based laboratories that specialize in saliva analyses. One hundred young adults (Mean age: 23.10 years; 62 females) donated 2 mL of whole saliva by passive drool. Each sample was split into multiple- 100 μL aliquots and …

School-based concussion management programs cover thousands of young athletes, yet there is little in the way of research to assess program processes or outcomes. This study examined the referral patterns of consultants working with ten high school concussion management programs. In addition to the number of referrals made to specialists, other potential outcome variables were explored. The sample included over 5,000 athlete-seasons and 298 concussions managed directly by certified athletic trainers. All programs used computerized neuropsychological testing (both baseline and post injury). Two groups were compared: five programs used a clinical neuropsychologist (NP) as the testing consultant and five used …

Chronic ankle instability (CAI) is often debilitating and may be affected by a number of intrinsic and environmental factors. Alterations in neurocognitive function and attention may contribute to repetitive injury in those with CAI and influence postural control strategies. Thus, the purpose of this study was to determine if there was a difference in attentional functioning and static postural control among groups of Comparison, Coper and CAI participants and assess the relationship between them within each of the groups. Recruited participants performed single-limb balance trials and completed the CNS Vital Signs (CNSVS) computer-based assessment to assess their attentional function. Center …

Sandbagging On The Immediate Post-Concussion Assessment And Cognitive Testing (Impact) In A High School Athlete Population, Kathryn L. Higgins, Robert L. Denny, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty Publications
The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called “sandbagging,” in order to return to their baseline cognitive scores, and thus to play, more quickly. This research examines ImPACT baseline scores when high school athletes were asked to attempt to “sandbag,” and compares those scores with scores …

Objective: This paper reviews the state of the science on psychological and neural contributions to appetite self-regulation in the context of obesity. Methods: Three content areas (neural systems and cognitive functions; parenting and early childhood development; and goal setting and goal striving) served to illustrate different perspectives on the psychological and neural factors that contribute to appetite dysregulation in the context of obesity. Talks were initially delivered at an NIH workshop consisting of experts in these three content areas, and then content areas were further developed through a review of the literature. Results: Self-regulation of appetite involves a complex interaction …

High levels of endurance training have been associated with potentially negative health outcomes and addictive-like symptoms such as exercise in the presence of injury and higher levels of impulsivity. This pilot study examined the relationships among self-report measures of addictive symptoms related to exercise and behavioral and neural measures of impulsivity in endurance runners. We hypothesized endurance runners would have increased preference for immediate rewards and greater activation of cognitive control regions when making decisions involving delayed rewards. Twenty endurance runners (at least 20 miles/week) were recruited to undergo measures of self-report exercise addiction symptoms, impulsive decision-making (delay discounting) and …

Lateral hypothalamic area (LHA) local field potentials (LFPs) were recorded in a Prader–Willi patient undergoing deep brain stimulation (DBS) for obesity. During hunger, exposure to food-related cues induced an increase in beta/ low-gamma activity. In contrast, recordings during satiety were marked by prominent alpha rhythms. Based on these findings, we have delivered alphafrequency DBS prior to and during food intake. Despite reporting an early sensation of fullness, the patient continued to crave food. This suggests that the pattern of activity in LHA may indicate hunger/satiety states in humans but attest to the complexity of conducting neuromodulation studies in obesity.

Postural control and joint position sense are essential for safely undertaking leisure and professional activities, particularly at high altitude. We tested whether exposure to a 12-day trek with a gradual ascent to high altitude impairs postural control and joint position sense. This was a repeated measures observational study of 12 military service personnel (28±4 years). Postural control (sway velocity measured by a portable force platform) during standing balance, a Sharpened Romberg Test and knee joint position sense were measured, in England (113m), and at 3 research camps (3619m, 4600m and 5140m) on a 12-day high altitude trek in the Dhaulagiri …

Alterations in microRNA (miRNA) expression may contribute to COPD pathogenesis. In COPD, lung fibroblast repair functions are altered in multiple ways, including extracellular mediator release. Our prior study revealed miR-503 expression is decreased in COPD lung fibroblasts, although the exact role played by miR-503 is undetermined. The current study examined a role of miR-503 in cytokine, growth factor and fibronectin production by lung fibroblasts from patients with and without COPD. Primary adult lung fibroblasts were isolated from patients with or without COPD. MiR-503 expression and interleukin (IL)-6, -8, PGE2, HGF, KGF, VEGF and fibronectin release were examined with or without …

Despite the apparent absence of external signs of consciousness, a significant proportion of behaviorally nonresponsive patients can respond to commands by willfully modulating their brain activity. However, little is known about the mental life of these patients. We discuss a recent innovative approach, which sheds light on the preserved cognitive capacities of these patients, including executive function, theory of mind, and the experience of affective states. This research represents a fundamental shift in our understanding of these patients, and has important implications for both their continued treatment and care. Moreover, this research marks out avenues for future inquiry into the …

Most debilitating neurological disorders can have anatomical origins. Yet unlike other body organs, the anatomy alone cannot easily provide an understanding of brain functionality. In fact, addressing the challenge of linking structural and functional connectivity remains in the frontiers of neuroscience. Aggregating multimodal neuroimaging datasets may be critical for developing theories that span brain functionality, global neuroanatomy and internal microstructures. Functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) are main such techniques that are employed to investigate the brain under normal and pathological conditions. FMRI records blood oxygenation level of the grey matter (GM), whereas DTI is able …

Many tissues contain adult mesenchymal stem cells (MSCs), which may be used in tissue regeneration therapies. However, the MSC availability in most tissues is limited which demands expansion in vitro following isolation. Like many developing cells, the state of MSCs is affected by the surrounding microenvironment, and mimicking this natural microenvironment that supports multipotent or differentiated state in vivo is essential to understand for the successful use of MSC in regenerative therapies. Many researchers are, therefore, optimizing cell culture conditions in vitro by altering growth factors, extracellular matrices, chemicals, oxygen tension, and surrounding pH to enhance stem cells self-renewal or …

BACKGROUND: There have been a number of candidate gene association studies of cancer cachexia-related traits, but no genome-wide association study (GWAS) has been published to date. Cachexia presents in patients with a number of complex traits, including both cancer and COPD. The objective of the current investigation was to search for a shared genetic aetiology for change in body mass index (ΔBMI) among cancer and COPD by using GWAS data in the Framingham Heart Study.
METHODS: A linear mixed effects model accounting for age, sex, and change in smoking status was used to calculate ΔBMI in participants over 40 years …
Assessment Of Coronary Artery Outward Remodeling In Consequence Of Excision Of Epicardial Adipose Tissue In Ossabaw Swine, Kelly Coderre
Assessment Of Coronary Artery Outward Remodeling In Consequence Of Excision Of Epicardial Adipose Tissue In Ossabaw Swine, Kelly Coderre
Undergraduate Honors Thesis Collection
Background
Coronary artery disease (CAD) results from the buildup of cholesterol, inflammatory factors, and proliferating smooth muscle cells within a vessel wall. This plaque impedes on the vessel lumen, decreasing the space through which blood can flow, leading to an array of complications in the human body. To offset these effects, the arterial wall undergoes outward remodeling, a compensatory physiologic phenomenon that blood vessels undertake when burdened with a blockage, such as CAD. In a previously conducted study, a coronary epicardial adipose tissue excision (cEATx) surgery was performed above the left anterior descending (LAD) in Ossabaw swine to investigate the …

Title: Use of personalized patient heart diagrams at the bedside to improve quality of care
Background/Introduction: With congenital heart disease no two hearts are exactly the same. Even with the same lesion, the anatomy of the heart can be completely different. In response to a bedside nursing idea following a cardiac arrest, advanced practice nurses (APN) initiated a program to provide personalized cardiac anatomy diagrams at the bedside of every patient on the cardiology service.
Methods: When a cardiac patient is admitted to cardiology floor, the nurse will check the patients chart for an anatomy picture, then will place …
