Background: Appendectomy is considered the gold standard treatment for acute appendicitis. Recently the need for surgery has been challenged in both adults and children. In children there is growing clinician, patient and parental interest in non-operative treatment of acute appendicitis with antibiotics as opposed to surgery. To date no multicentre randomised controlled trials that are appropriately powered to determine efficacy of non-operative treatment (antibiotics) for acute appendicitis in children compared with surgery (appendectomy) have been performed.
Methods: Multicentre, international, randomised controlled trial with a non-inferiority design. Children (age 5-16 years) with a clinical and/or radiological diagnosis of acute uncomplicated appendicitis …

Prebiotics And Inflammatory Bowel Disease, Heather Rasmussen, Bruce R. Hamaker
Prebiotics And Inflammatory Bowel Disease, Heather Rasmussen, Bruce R. Hamaker
Department of Nutrition and Health Sciences: Faculty Publications
Inflammatory bowel disease risk factors include poor diet, and corresponding low intake of dietary fiber, specifically prebiotics, which is fermented by the gut microbiota. Dietary fibers, many of which are potential prebiotics, have hundreds to thousands of unique chemical structures that may promote bacteria or bacterial groups to provide beneficial health effects. In vitro and in vivo animal models provide some support for the use of prebiotics for inflammatory bowel disease through inflammation reduction. Studies using prebiotics in patients with inflammatory bowel disease are limited and focus on only a select few prebiotic substances.

The Neuropsychology Of Sport And Performance, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty and Staff 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 …

Validity And Reliability Of Baseline Testing In A Standardized Environment, Kathryn L. Higgins, Todd Caze, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty and Staff 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 and Staff 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 …

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.

Enhanced Breast Cancer Classification With Automatic Thresholding Using Support Vector Machine And Harris Corner Detection, Mohammad Taheri
Electronic Theses and Dissertations
Image classification and extracting the characteristics of a tumor are the powerful tools in medical science. In case of breast cancer medical treatment, the breast cancer classification methods can be used to classify input images as benign and malignant classes for better diagnoses and earlier detection with breast tumors. However, classification process can be challenging because of the existence of noise in the images, and complicated structures of the image. Manual classification of the images is timeconsuming, and need to be done only by medical experts. Hence using an automated medical image classification tool is useful and necessary. In addition, …
Halo- And Solvato-Fluorochromic Polymer Nanoassemblies For Cancer Theranostics, Derek Alexander Reichel
Halo- And Solvato-Fluorochromic Polymer Nanoassemblies For Cancer Theranostics, Derek Alexander Reichel
Theses and Dissertations--Pharmacy
Theranostics is an emerging treatment approach that combines diagnostics with therapy in order to personalize treatment regimens for individual patients and decrease cancer mortality. Previously, nanoparticles entrapping conventional fluorescent dyes were developed for cancer theranostics, but fluorescent nanoparticles did not allow clinicians to significantly improve cancer treatments.
The use of fluorescent dyes that are sensitive to solvent acidity (halo-fluorochromism) and polarity (solvato-fluorochromism) may overcome the limitations of fluorescent nanoparticles and improve cancer therapy by enabling researchers to detect chemical properties within the nanoparticle core environment. The model halo- and solvato-fluorochromic dye Nile blue was attached to the core of nanoscale …

Background Context: Disc degeneration is the leading cause of low back pain and is often characterized by a loss of disc height, resulting from cleavage of chondroitin sulfate proteoglycans (CSPGs) present in the nucleus pulposus. Intact CSPGs are critical to water retention and maintenance of the nucleus osmotic pressure. Decellularization of healthy nucleus pulposus tissue has the potential to serve as an ideal matrix for tissue engineering of the disc because of the presence of native disc proteins and CSPGs. Injectable in situ gelling matrices are the most viable therapeutic option to prevent damage to the anulus fibrosus and future …
