Conformation Dependent Monoclonal Antibodies Distinguish Different Replicating Strains Or Conformers Of Prefibrillar Aβ Oligomers, Rakez Kayed, Isabel Canto, Leonid Breydo, Suhail Rasool, Tamas Lukacsovich, Jessica Wu, Ricardo Albay, Anna Pensalfini, Stephen Yeung, Elizabeth Head, J. Lawrence Marsh, Charles Glabe

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Age-related neurodegenerative diseases share a number of important pathological features, such as accumulation of misfolded proteins as amyloid oligomers and fibrils. Recent evidence suggests that soluble amyloid oligomers and not the insoluble amyloid fibrils may represent the primary pathological species of protein aggregates.

RESULTS: We have produced several monoclonal antibodies that specifically recognize prefibrillar oligomers and do not recognize amyloid fibrils, monomer or natively folded proteins. Like the polyclonal antisera, the individual monoclonals recognize generic epitopes that do not depend on a specific linear amino acid sequence, but they display distinct preferences for different subsets of prefibrillar oligomers. Immunological …

A Case Study Of Appendicitis At Antanimalandy Lutheran Hospital, Jennifer Gemmell

Independent Study Project (ISP) Collection

From the introduction:

The island of Madagascar houses a total of 19,159,000 people who spend only $34 per person per year on health care (“Madagascar,” 2008). The government claims to have “committed itself to the principle that good health is a right of each Malagasy citizen, and has made significant studies in the area of health care,” according to the country study for the Library of Congress. However, with political corruption, political crisis after political crisis, and lack of international support, the government does not dispense the funds necessary to support this commitment (Metz, 1994). For example, in 1976 the …

Preventive Care Utilization Among Black Women : Perceived Beliefs, Benefits And Barriers To Mammography Screening, Rowandalla Y. Dunbar

Loma Linda University Electronic Theses, Dissertations & Projects

Blacks, in comparison to other racial or ethnic groups, suffer higher rates of illness and death from many preventable or treatable diseases. Despite the significantly higher rates of mortality and disease, Blacks are least likely to utilize clinical preventive care services. Black women, who are more likely to have advanced breast cancer at time of diagnosis (Chu, Lamar, & Freeman, 2003) are least likely to seek mammography screening (National Health Interview Study, 2000). Allen, Bastani, Bazargan and Leonard (2002) examined predictors of mammography screening among women 40 years old and older residing in the South Central area of Los Angeles, …

Deficient Liver Biosynthesis Of Docosahexaenoic Acid Correlates With Cognitive Impairment In Alzheimer's Disease, Giuseppe Astarita, Kwang-Mook Jung, Nicole C. Berchtold, Vinh Q. Nguyen, Daniel L. Gillen, Elizabeth Head, Carl W. Cotman, Daniele Piomelli

Sanders-Brown Center on Aging Faculty Publications

Reduced brain levels of docosahexaenoic acid (C22:6n-3), a neurotrophic and neuroprotective fatty acid, may contribute to cognitive decline in Alzheimer's disease. Here, we investigated whether the liver enzyme system that provides docosahexaenoic acid to the brain is dysfunctional in this disease. Docosahexaenoic acid levels were reduced in temporal cortex, mid-frontal cortex and cerebellum of subjects with Alzheimer's disease, compared to control subjects (P = 0.007). Mini Mental State Examination (MMSE) scores positively correlated with docosahexaenoic/α-linolenic ratios in temporal cortex (P = 0.005) and mid-frontal cortex (P = 0.018), but not cerebellum. Similarly, liver docosahexaenoic acid content was lower in Alzheimer's …

Concurrent Sexual Partnerships Do Not Explain The Hiv Epidemics In Africa: A Systematic Review Of The Evidence, Larry Sawers, Eileen Stillwaggon

Economics Faculty Publications

The notion that concurrent sexual partnerships are especially common in sub-Saharan Africa and explain the region’s high HIV prevalence is accepted by many as conventional wisdom. In this paper, we evaluate the quantitative and qualitative evidence offered by the principal proponents of the concurrency hypothesis and analyze the mathematical model they use to establish the plausibility of the hypothesis.

We find that research seeking to establish a statistical correlation between concurrency and HIV prevalence either finds no correlation or has important limitations. Furthermore, in order to simulate rapid spread of HIV, mathematical models require unrealistic assumptions about frequency of sexual …

Body Image Satisfaction In Infant And Pediatric Cardiac Transplant Recipients As Adolescents, Danusia Nedilskyj

Loma Linda University Electronic Theses, Dissertations & Projects

With the long-term survival rate of infant and pediatric heart transplant recipients reaching as high as 85%, there is now a significant number of these youths entering adolescence. Although psychological factors thought to be associated with pediatric heart transplant have reached clearer delineation in the literature, few studies have been conducted. Given the emphasis on development typically seen in adolescence combined with the unique experience of receiving a heart transplant, factors such as body image, self-perception, stress and mood have emerged from the literature. As such, this study assessed psychosocial variables of body image satisfaction, self-concept, depression, and social stress …

Psychological Profiles In A Female Bariatric Surgery Sample, Aimee L. Donato

Loma Linda University Electronic Theses, Dissertations & Projects

Morbid obesity is an epidemic. Current literature suggests that people with morbid obesity tend to show increased levels of psychological dysfunction. This is especially pertinent to the clinicians who work with morbidly obese patients who seek bariatric surgery as the method for weight control. Surgery should be performed on patients who are psychologically ready to adjust to the stringent post-operative lifestyle.

The purpose of the present study was (1) to compare two groups of bariatric patients (a White group and a non-White group) on pre-surgery measures: specific scales on the Millon Behavioral Medicine Diagnostic (MBMD), the Beck Depression Inventory II …

Objectives: This study examined the relationship between substance use disorder (SUD) and intimate partner violence screening (IPV) and management practices in the emergency department (ED). Methods: This was a retrospective cohort study of adult ED patients presenting to an urban, tertiary care teaching hospital over a 4-month period. An automated electronic data abstraction process identified consecutive patients and retrieved visit characteristics, including results of three violence screening questions, demographic data, triage acuity, time of visit, and ICD-9 diagnosis codes. Data on management were collected using a standardized abstraction tool by two reviewers masked to the study question. Multivariate logistic regression …

The Role Of Unrealistic Optimism In Explaining Preventive Behaviors In High Versus Low Endemic Malaria Settings In Belize, Daniel G. Handysides

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Of all the diseases an individual can encounter in the world, malaria is one of the most destructive. Simple measures like sleeping under a bednet would greatly reduce the burden (Abeku, 2007). When people estimate their risk relative to others, they are most often unrealistically optimistic, which may explain why those at risk often fail to perform behaviors, such as using a bednet that will reduce their risk. However, one study showed that people at high risk for malaria held pessimistic perceptions of their risk for the disease, but the reasons for this finding are unclear (Morrison, Ager, & …

The Relationship Between The Level Of Support Group Participation And Psychosocial Factors In Prostate Cancer Patients Treated With Proton Therapy, Carol A. L. Davis

Loma Linda University Electronic Theses, Dissertations & Projects

Background. The role of support groups for cancer patients is known to be beneficial in helping people adjust to the disease, and cope with the myriad of effects that cancer has on quality of life. Although many people express interest in attending such support groups, few attend regularly. It is unclear what characteristics distinguish those who use such services from those who do not, especially among proton therapy patients.

Objective. To examine demographic and psychosocial characteristics associated with the Brotherhood of the Balloon (BOB) prostate cancer support group membership, a unique treatment-focused group originating at Loma Linda University Medical Center …

Program Evaluation Of A Community-Based Door-Through-Door Medical Escort Service, Lauren A. Martin

Gerontology Institute Publications

This report summarizes the program evaluation findings of a Boston-based organization’s Medical Escort program. This “door-through-door” service strives to provide medical transportation, physical assistance, and emotional support to elders on their way to the doctor’s office, during medical appointments and on the way back home again. By offering added assistance the program attempts to remove environmental barriers associated with access to health care. This evaluation combines previously collected program statistics with surveys (32) from program volunteers and phone interviews (78) with recipients.

Asian Race/Ethnicity As A Risk Factor For Bile Duct Injury During Cholecystectomy., Stephanie R. Downing, Ghazala Datoo, Tolulope A. Oyetunji, Terrence Fullum, David C. Chang, Nita Ahuja

Manuscripts, Articles, Book Chapters and Other Papers

Iatrogenic bile duct injury (BDI) is an uncommon but serious complication of cholecystectomy, with identified risk factors of acute cholecystitis, male sex, older age, and aberrant biliary anatomy. The Nationwide Inpatient Sample (1998-2006) was queried for cholecystectomy performed on hospital day 0 or 1. Bile duct injury repair procedure codes were used as a surrogate for BDI. We identified 377,424 patients who underwent cholecystectomy, with 1124 BDIs (0.3%). On multivariate logistic regression analysis, Asian race/ethnicity was a significant risk factor for BDI (odds ratio [OR], 2.26; 95% confidence interval [CI], 1.59-3.23; P < .001). This persisted for laparoscopic (OR, 2.62; 95% CI, 1.28-5.39; P = .009) and open (2.21; 1.59-3.07; P < .001) cholecystectomies. No other race/ethnicity was identified as a risk factor for BDI. We report a new finding that Asian race/ethnicity is a significant risk factor for BDI in laparoscopic and open cholecystectomies.

Psychology Of Sport Injury : A Holistic Approach To Rehabilitating The Injured Athlete, Jennifer Jordan Utley

Athletic Training Collection

Sports medicine practitioners must consider both physical and mental aspects of injury to fully rehabilitate the injured athlete. The psychological distress that follows injury has been well documented and calls for a change in the rehabilitation of injured athletes.^1-3 With the recent emergence of sport psychology and the emphasis on competitive sport in the United States and beyond, psychological skills are no longer solely utilized by the elite athlete; college and high school athletes are gaining instruction in the use of psychological skills from sport psychologists, coaches, and fellow teammates. Psychological skills have been shown to be effective in …

Use Of An Animal Model To Explore Prenatal Predictors Of Insulin And Glucose Metabolism In Southwestern Alaskan Yupiit, Julie Jo Kachinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Compared to other North American indigenous populations, Southwest Alaskan Yupiit exhibit very low rates of type 2 diabetes despite the occurrence of common risk factors. Contemporary Yupiit obtain a substantial portion of their calories from traditional foods, which contain high amounts of omega-3 polyunsaturated fatty acids. Epidemiological and experimental animal research has linked glucose and insulin homeostasis with a diet high in omega-3s. This study used an experimental animal model to explore potential diabetes protective effects (for adult offspring) of prenatal maternal nutrition modeled on traditional locally-obtained Yupiit diets. The results of this study showed that the adult offspring whose …

Access to patient-centered and equitable emergency care is critical to a community, and EDs are the safety net that must provide that care whenever it is needed, to whomever needs it. A wellmanaged ED increases the quality and safety of patient care and strengthens the health care infrastructure.

Omega-3 Fatty Acids: Potential Role In The Management Of Early Alzheimer's Disease, Gregory A. Jicha, William R. Markesbery

Sanders-Brown Center on Aging Faculty Publications

Omega-3 fatty acids are essential for brain growth and development. They play an important role throughout life, as critical modulators of neuronal function and regulation of oxidative stress mechanisms, in brain health and disease. Docosahexanoic acid (DHA), the major omega-3 fatty acid found in neurons, has taken on a central role as a target for therapeutic intervention in Alzheimer's disease (AD). A plethora of in vitro, animal model, and human data, gathered over the past decade, highlight the important role DHA may play in the development of a variety of neurological and psychiatric disorders, including AD. Cross sectional and prospective …

Neural Activity In The Hippocampus And Perirhinal Cortex During Encoding Is Associated With The Durability Of Episodic Memory, V. A. Carr, Indre Viskontas, S. A. Engel, B. J. Knowlton

Psychology

Studies examining medial temporal lobe (MTL) involvement in memory formation typically assess memory performance after a single, short delay. Thus, the relationship between MTL encoding activity and memory durability over time remains poorly characterized. To explore this relationship, we scanned participants using high-resolution functional imaging of the MTL as they encoded object pairs; using the remember/know paradigm, we then assessed memory performance for studied items both 10 min and 1 week later. Encoding trials were classified as either subsequently recollected across both delays, transiently recollected (i.e., recollected at 10 min but not after 1 week), consistently familiar, or consistently forgotten. …

A Program To Promote Physical Activity And Healthy Body Weight In An Adolescent Female: A Case Study, Katie Stoddard

Kinesiology and Public Health

A case study of an obese 14-year-old female was conducted to assess her body weight and dietary and physical activity habits. The purpose of this study was to promote weight loss through improved dietary practices and an increase in energy expenditure. This was done by monitoring and altering caloric intake and engaging in regular, vigorous physical activity. Furthermore, the subject increased health-related knowledge, developed new skills, and ultimately attempted behavior modification. From April to September 2009, the subject participated in a minimum of two supervised exercise sessions per week to increase her energy expenditure and to teach her strategies for …

Laterality, Perception, And Action During The Size-Weight Illusion, Gavin Buckingham, Nathalie S. Ranger, Melvyn A. Goodale

Psychology Presentations

In the classic size-weight illusion (SWI), a small object will feel heavier than an larger object of equal weight (Charpentier, 1891). Individuals continue to perceive this illusory difference in weight long after their gripping and lifting forces have scaled to the actual, identical, mass of the illusion-inducing stimuli (Flanagan & Beltzner, 2000).

The independence of our weight perception and fingertip force application has only been quantified in the right hand of right-handers. The immunity to this perceptual illusion may be affected by manual asymmetries (e.g., Gonzalez, Ganel & Goodale, 2006).

We examined perception of heaviness and fingertip force scaling in …

Effect Of Dai Training On Maternal And Neonatal Care: An Operations Research Study, Peter C. Miller, Gul Rashida, Abdul Wajid, Zeba Tasneem, Lubna Mahmood, Minhaj Ul Haque

Reproductive Health

This study examines the use of training traditional birth attendants, or "dais" as they are known in Pakistan, to reduce maternal mortality. By training dais to adopt safer routine delivery, newborn care practices, and recognize and refer in case of emergencies, dais can improve maternal and neonatal health. While one group of women met with specially trained dais who received Safe Motherhood Applied Research Training (SMART), a control group met with dais who offered health services only. The objectives of this evaluation were to determine whether dais substantially improved their performance after attending the "SMART dai" training course, to determine …
