Botulism In Children: A Diagnostic Dilemma In Developing Countries, Muhammad Rehan Khan, Prem Kumar, Shahnaz Shahid, Anwarul Haque

Department of Paediatrics and Child Health

Botulism is a well-known disease of the neuromuscular junction. It is a rare but curable cause of paralysis in paediatric population. In addition to classical clinical signs and symptoms, the diagnosis of botulism requires laboratory confirmation of intoxication by various biological tests. These include demonstration of botulinum toxin in serum or isolation of the Clostridium botulinum from stool/gastric aspirates. However, it is not always possible to confirm intoxication due to unavailability of technical facilities, especially in resource limited countries like Pakistan. Under these circumstances, electrophysiological studies serve as an excellent diagnostic tool. These studies can provide quick diagnosis of botulism …

Augmentation Of Propensity Scores For Medical Records-Based Research, Mikel Aickin

COBRA Preprint Series

Therapeutic research based on electronic medical records suffers from the possibility of various kinds of confounding. Over the past 30 years, propensity scores have increasingly been used to try to reduce this possibility. In this article a gap is identified in the propensity score methodology, and it is proposed to augment traditional treatment-propensity scores with outcome-propensity scores, thereby removing all other aspects of common causes from the analysis of treatment effects.

The Case For Intervention Bias In The Practice Of Medicine., Andrew J Foy, E J Filippone

Department of Medicine Faculty Papers

Bias is an inclination to present or hold a partial perspective at the expense of possibly equal or more valid alternatives. In this paper, we present a series of conditional arguments to prove that intervention bias exists in the practice of medicine. We then explore its potential causes, consequences, and criticisms. We use the term to describe the bias on the part of physicians and the medical community to intervene, whether it is with drugs, diagnostic tests, non-invasive procedures, or surgeries, when not intervening would be a reasonable alternative. The recognition of intervention bias in medicine is critically important given …

Dynamic Optimization Of Caregiver Schedules Based On Vital Sign Streams, Mohamed Saad, Bilal Khan

Publications and Research

Hospital facilities use a collection of heterogeneous devices, produced by many different vendors, to monitor the state of patient vital signs. The limited interoperability of current devices makes it difficult to synthesize multivariate moni- toring data into a unified array of real-time information regarding the patients state. Without an infrastructure for the integrated evaluation, display, and storage of vital sign data, one cannot adequately ensure that the assignment of care- givers to patients reflects the relative urgency of patient needs. This is an especially serious issue in critical care units (CCUs). We present a formal mathematical model of an operational …

Evaluation Of Clinical Outcomes Of Prophylactic Versus Preemptive Cytomegalovirus Strategy In Liver Transplant Recipients, Ifeanyi Onor, Sarah Todd, Erika Meredith, Sebastian Perez, Aneesh Mehta, G Lyon, Stuart Knechtle, Steven Hanish

Faculty and Staff Publications

Cytomegalovirus (CMV) is a major cause of morbidity and mortality following solid organ transplantation (SOT). Two strategies, prophylactic, and preemptive have emerged for the prevention of CMV infection and disease after SOT. This retrospective chart review of two liver transplant cohorts: prophylactic and preemptive, compares the clinical impact of transitioning from prophylactic to preemptive strategy. The primary outcome is the incidence of CMV viremia at 3-and 6-months post-transplant. Secondary outcomes include: incidence of CMV tissue-invasive disease, acute cellular rejection, leukopenia and neutropenia, opportunistic infection rates, hospital readmission rates, and mortality at 3-and 6-months post-transplant. A total of 109 patients were …

Reliability Of The Myotonometer For Assessment Of Posterior Shoulder Tightness, Caitlyn M. Kerins, Stephanie D. Moore, Timothy A. Butterfield, Patrick O. Mckeon, Timothy L. Uhl

Physical Therapy Faculty Publications

BACKGROUND/PURPOSE: The Myotonometer® is an electronic tissue compliance meter that has been used to quantify the compliance of soft tissues. The Myotonometer® may be a valuable tool to measure the effectiveness of interventions commonly used to increase tissue compliance in individuals with posterior shoulder tightness (PST). Limited data exist on reliability and responsiveness of the Myotonometer® for assessment of soft tissues about the shoulder; therefore, the purpose of this study is to determine the intra- and inter-session reliability and responsiveness of the Myotonometer® in measuring tissue compliance of the posterior shoulder musculature in asymptomatic subjects with PST.

METHODS: Fifteen asymptomatic …

Advancing The Right To Health Through Global Organizations: The Potential Role Of A Framework Convention On Global Health, Eric A. Friedman, Lawrence O. Gostin, Kent Buse

Georgetown Law Faculty Publications and Other Works

Organizations, partnerships, and alliances form the building blocks of global governance. Global health organizations thus have the potential to play a formative role in determining the extent to which people are able to realize their right to health.

This article examines how major global health organizations, such as WHO, the Global Fund to Fight AIDS, TB and Malaria, UNAIDS, and GAVI approach human rights concerns, including equality, accountability, and inclusive participation. We argue that organizational support for the right to health must transition from ad hoc and partial to permanent and comprehensive.

Drawing on the literature and our knowledge of …

Dissertations

The aim of this three-paper dissertation was to examine the relationship between fall risk, executive function (EF) and mild cognitive impairment (MCI) in community dwelling older adults. Papers one and two describe how mild changes in cognition influence performance on four measures of fall risk, the Five Times Sit to Stand Test (FTSTS), usual gait speed, the Timed Up and Go (TUG) test, and the Activities Specific Balance Confidence Scale (ABC) in a group of community dwelling older adults. The third paper describes if participation in a progressively challenging domain specific computerized cognitive training intervention influenced performance on measures of …

A Prospective Examination Of Mindfulness Training On The Mitigation Of Postraumatic Stress Symptoms, Abby E. Blankenship

Dissertations

The current study investigated the ability of a one-session computerized mindfulness intervention to mitigate posttraumatic stress disorder (PTSD)-like symptoms in response to a trauma analogue. Ninety-two participants were randomly assigned to either mindfulness training or no treatment. Participants assigned to the mindfulness training completed a 1-hour computerized mindfulness training and practiced their skills for 1 week. All participants were exposed to an analogue for real-life trauma and were assessed at 1- and 2-week follow-up. Participants assigned to the mindfulness condition exhibited significantly lower levels of PTSD-like symptoms at 2-week follow-up in comparison to the no treatment condition. In addition, participants …

Motivational Interviewing Assessment And Behavior Therapy As A Stepped-Care Approach To The Treatment Of Adolescent Depression, Tanya N. Douleh

Dissertations

Depression is a significant public health concern with a lifetime prevalence of 24.01 for adolescents in grades 9-12 (Lewinsohn, Hops, Roberts, Seeley, & Andrews, 1993) and a point prevalence of 4-6% (Kessler, Avenevoli, & Ries, 2001). The risks associated with adolescent onset depression include comorbidity, depressive episodes continuing into adulthood, and suicidality. These risks make it imperative to develop effective treatments to address adolescent depression. Stepped care is an approach to treatment which involves treatment of illness using the least invasive measures first and moving toward more invasive treatment as indicated by ongoing assessment. Through a single-participant design, the current …

Discovery And Characterization Of A Tanapoxvirus Encoded Human Neuregulin Mimetic, David Jeng

Dissertations

Studies on large dsDNA viruses such as poxviruses have been helpful in identifying a number of viral and cellular growth factors that contribute to our broad understanding of virus-host interaction. Orthopoxviruses and leporipoxviruses are among the most studied viruses in this aspect. However, tanapoxvirus (TPV) a member of the genus Yatapoxvirus, still remains largely unexplored, as the only known hosts for this virus are humans and monkeys. Here, we describe the initial characterization of an EGF-like growth factor mimicking human neuregulin from TPV, expressed by the TPV-15L gene. Assays using a baculovirus expressed and tagged TPV-15L protein demonstrated the ability …

Establishment And Validation Of A Novel Fucci (Fluorescent Ubiquitination-Based Cell Cycle Indicator) In An In Vitro Chronic Myeloid Leukemia Model, Jane Marie Isquith

Master's Theses

The deregulation of the cell cycle is important in the leukemic transformation and in the continued discovery of more efficient targeted therapies. After elucidation of the role of the RNA editor ADAR1 in the malignant reprogramming of Chronic Myeloid Leukemia (CML) progenitors to leukemia stem cells (LSCs) during the chronic phase to blast crisis stages of the disease, current research seeks to uncover the mechanism of action of ADAR1 in this process. To study the potential role ADAR1 plays in the changes to cell cycle during this disease progression, a novel Fucci (fluorescent ubiquitination-based cell cycle indicator) system was introduced …

Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite

Masters Theses

The aim of this study was to develop a series of vignettes to form the basis for an assessment of executive functions (EFs) for 9 – 12 year old children. Although EFs are necessary for effective social communication and positive social interactions, currently, most EF assessments focus on impersonal activities. Little research exists that incorporates real-time processing using ecologically valid social scenarios. The current study aims to develop realistic scenarios that children could encounter in daily life. Ethnographic interviews were conducted with six participants, who worked in a school with 9-12 year old children, to gain their perspective on social …

Explicit Teacher-Implemented Phoneme Awareness Instruction: Preschool Effects, Heather M. Osterhouse

Masters Theses

The purpose of the current study was to investigate the impact of explicit, concentrated, teacher-implemented phonological awareness instruction for ―at risk‖ 4- year-olds. Early childhood educators were trained to implement a 10-week program delivered for 20-minute sessions, four times a week, in their classrooms. The program focused on phonological awareness beginning at the level of letter-sound knowledge and advancing to blending and segmenting constituent phonemes in words. Pre- to post-treatment comparisons of phonological awareness and letter knowledge skills indicated that children in the experimental group made significant gains in comparison to the control group in phoneme blending and letter knowledge. …

Dynamic Modeling Of Nonmedical Opioid Initiation: Epidemic And Access, Alexandra Nielsen, Teresa D. Schmidt, Dennis Mccarty, Wayne W. Wakeland

Complex Systems Faculty Publications and Presentations

We report development of a systems level dynamic model of initiation and nonmedical use of pharmaceutical opioids in the US. The model calibrated to 1995-2005 National Survey of Drug Use and Health (NSDUH) data, predicts 2006-2011 data well. Preliminary findings indicate that interventions which reduce the perceived attractiveness of opioids for recreational use may be able to reduce initiation and nonmedical use most significantly, while supply restriction effected through drug take back days and prescribing changes may have more modest effects. We argue that system dynamics is an effective approach for evaluating potential interventions to this complex system where the …

We report a case of gastroschisis which was not diagnosed antenatally and was delivered through lower segment caesarean section due to non-reassuring cardiotocograph and small for gestational age fetus in a 21-year old mother. It was associated with oligohydramnios and partial extension of wrist joint in the neonate. After delivery, baby was referred to tertiary care for specialized care by paediatric surgeon and neonatologist where he had silo reduction and surgical repair. Postnatally, the baby is in healthy condition till now.

Vegf And Sympathetic Perivascular Nerves Contribute To Hypoxic Remodeling Of Ovine Cranial Arteries, Olayemi Olufikayo Adeoye

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic hypoxia complicates many pregnancies and can result in postnatal pathologies that include compromised fetal cardiovascular structure and function. Mechanisms involved remain unclear. Because hypoxia increases production of VEGF, known to modulate smooth muscle (SM) phenotype, this thesis explored the hypothesis that VEGF contributes to hypoxic fetal vascular remodeling through direct effects on SM cells and indirectly through perivascular nerves. Using a chronic hypoxia sheep model, this work demonstrated that: 1) hypoxia potently upregulates VEGF receptor expression but not endogenous VEGF level in fetal ovine carotid arteries; 2) both chronic hypoxia and VEGF exert similar effects on smooth muscle contractile …

Sleep-Wake Cycle Assessment In Type 2 Diabetes And Salivary Melatonin Correlates, Paula Regina Aguiar Cavalcanti

Loma Linda University Electronic Theses, Dissertations & Projects

p=.047). Additionally, there were significant inverse relationships between melatonin collected at two hours before bed time and latency (ρ=-.87; p=.001), wake after sleep onset (ρ =-.69; p=.02) and nocturnal activity (ρ =-.67; p=.03). Latency was inversely correlated with melatonin collected at bed time (ρ =-.69; p=.02). These findings suggest that T2DM presents disturbances in the homeostatic and circadian drives, mainly characterized by less consistency across days of the daily circadian signal, higher rhythm fragmentation and lower rhythm amplitude. In addition to the lower melatonin levels, the decrease in the amplitude of the activity rhythm may also be involved in circadian …

Buffering Effect Of Relational Support In African American Marriages, Aimee Galick

Loma Linda University Electronic Theses, Dissertations & Projects

Racial discrimination is a common experience for African Americans in this country. Racial discrimination can have a negative effect on the physical and mental health of marital partners, as well the quality and stability of the relationship. Few studies investigate relational support as an important coping strategy. Bodenmann's (1995) divorce-stress model asserts that positive dyadic coping strategies such as relational support can buffer partners and marriages from the negative consequences of stress. Socio-emotional relational therapy (SERT) provides marital and family therapists with a model of relational support in couple relationships. SERT's definition formed the basis for the conceptualization of relational …

Effect Of Procedural Pain On Purines, Mda And Allantoin In Premature Infants, Megan Sue Holden

Loma Linda University Electronic Theses, Dissertations & Projects

Identifying and measuring the biochemical effects of procedural pain in infants is a continuing challenge for clinicians. To address this issue we evaluated the relationship between procedural pain, ATP utilization (hypoxanthine and uric acid), and oxidative stress (MDA and allantoin) in premature infants. Through these studies we found that 1) a single heel-lance significantly increases plasma uric acid in rabbit kits, 2) tape removal increases MDA and prevents a decrease in uric acid in the plasma of premature infants, and 3) a single dose of oral sucrose before a heel-lance is sufficient to significantly increase plasma markers of ATP utilization …
