Evaluation Of The Survival Effect For Various Treatment Modalities Among Stage Ii And Iii Rectal Cancer Patients In California, 1994-2009, Myung Mi Cho

Loma Linda University Electronic Theses, Dissertations & Projects

Background: European trials evaluating the effect of preoperative (PreOP) versus postoperative chemoradiotherapy (PostOP CRT) found no survival benefit. However, the effect of a change from PostOP to PreOP CRT has not been evaluated in a population-based setting. We sought to evaluate multimodal treatment changes and overall survival for perioperative (PeriOP) CRT versus surgery alone and for PreOP versus PostOP CRT from 1994 through 2009 among patients receiving radical surgery for stage II and III rectal cancer (RC).

Patients and Methods: We conducted a nonconcurrent cohort study evaluating demographic predictors of multimodal therapy for stage II and III RC using …

The Morbidity & Mortality Of Prevalent Heart Failure, Jennifer Kwon

Loma Linda University Electronic Theses, Dissertations & Projects

The first study population included 292 unselected consecutive patients from the LLUMC heart failure clinic who were enrolled in the study from January to July 2006 and were followed up through the end of December 2010. The treatment policy at the clinic was to uptitrate dosages of beta-adrenergic blockade (β-blockers), angiotensin-converting-enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB) to the most tolerable levels in order to reach target dosages, as recommended by the Heart Failure Society of America (HFSA). Patients were classified into systolic heart failure (ejection fraction (EF) < 40%) or diastolic heart failure (EF≥40%). All dosages of β-blockers, ACEi and ARB were extracted through chart reviews and were used as the main predictors of the patients' survival. Results from analyses showed that reaching target dosages of β-blockers and ACEi/ARB may increase survival when compared to not reaching target among the systolic HF population (HR_{β_biockers}= 0.64, 95% CI 0.26-1.56 and HR_ACEi/ARB=0.50, …

Breastfeeding Attitudes And Intentions Among Middle Eastern Women Living In Southern California, Christina Irsilious Fam

Loma Linda University Electronic Theses, Dissertations & Projects

Background. Breastfeeding is unsurpassed as the preferred method of feeding infants all over the world due to the fact that its benefits far outweigh those of infant formula. Mothers from all cultures prefer breastfeeding, yet with immigration and emigration so widespread from developing countries, women's value systems are changing to adapt to their new surroundings. The United States has experienced a great influx of Middle Easterners; California in particular has a dominant presence of Middle Easterners. Many are faced with obstacles and stresses in acculturation, which may lead to lack of breastfeeding their infants. Few studies are available on Middle …

Relationship Between Nut Consumption And Memory Domains Of Cognitive Function Among Elderly Seventh-Day Adventists, Angeline B. David

Loma Linda University Electronic Theses, Dissertations & Projects

Objective. To determine the relationship between consumption of all types of nuts, tree nuts, and peanut and peanut butter and specific memory domains of cognitive function in a community-dwelling elderly population.

Design. Cross-sectional analysis using clinic data from the Biopsychosocial Religion and Health Study and dietary intake data from the Adventist Health Study-2.

Subjects/Methods. Adults aged 50 and older were administered the California Verbal Learning Test-II (CVLT) Short Form and provided self-report frequency and portion sizes of nut consumption, anthropometric measures, and other demographic, lifestyle, and clinic data. CVLT scores were age- and gender-strata specific z-scores normed to a …

Effects Of Photovoice On Youth Perceptions Of Healthy Food Access In The Built Environment, Sharlene A. Gozalians

Loma Linda University Electronic Theses, Dissertations & Projects

Background. Minority communities are at a higher risk for chronic diseases related to obesity because they lack access to stores that have affordable, fresh, nutritious foods that are necessary for a healthy diet. Photovoice can serve as a tool to engage youth in positive health behaviors and behavior change. Healthy food access has been analyzed based on nutrition, yet there is a lack of literature as to what factors enable and prevent access to healthy foods.

Methodology. The purpose of this study was to determine if a photovoice intervention would create a difference in perception of food access, empowerment …

The Association Of Diet With Affect, Patricia Ann Ford

Loma Linda University Electronic Theses, Dissertations & Projects

Nutrients such as omega-3 fatty acids have been associated with mental health yet few studies have examined whether foods protective or deleterious for cardiovascular disease affect mood. The purpose of this study was to examine associations between consumption of foods typical of Mediterranean and Western diets and fatty acids with positive and negative affect.

Adventist church attendees residing in North America completed a validated food frequency questionnaire in 2002-6 as part of the Adventist Health Study-2. A subset of these participants ^=9,121) completed the Positive and Negative Affect Schedule (PANAS) in the Biopsychosocial Religion and Health Study conducted in 2006-7. …

The Effect Of Non-Exercise Activity Thermogenesis On Subjects With Metabolic Syndrome, Samer Hammoudeh

Loma Linda University Electronic Theses, Dissertations & Projects

Metabolic syndrome is a cluster of metabolic abnormalities that increases the risk of cardiovascular disease and type 2 diabetes. Several criteria establish the diagnosis of metabolic syndrome, including high waist circumference, low HDL cholesterol, high triglycerides and glucose and above normal blood pressure. The prevalence of metabolic syndrome is on the rise following the rise in obesity across the globe. Qatar, a country in the Arabian Peninsula shares the burden of obesity with recent studies showing prevalences of'---61% among women and —39% among men. These studies found that metabolic syndrome is more common among women. Physical activity helps reduce visceral …

The Efficacy Of An Audio Program And Discussion Guide In Promoting Exclusive Breastfeeding In Cameroon, Africa, Kathryn R. Reinsma

Loma Linda University Electronic Theses, Dissertations & Projects

Background: In the Northwest Region of Cameroon, approximately 90% of women initiate breastfeeding; however, only 34% continue exclusive breastfeeding for the recommended six months (Kakute, et al., 2005; WHO, 2008). Entertainment-education is a mass-media communication strategy of placing educational information into media such as television programs, movies, and radio programs (Siegel & Lotenberg, 2007). This form of behavioral change communication has proven effective in addressing health-related issues in developing countries.

Purpose: The aim was to design an audio program and discussion guide to test the hypothesis that an audio program and discussion guide improves exclusive breastfeeding knowledge, beliefs, benefits, self-efficacy, …

Factors Affecting Parents Misperception Of Overweight Or Obesity In Their Children, Carol Barnes Reid

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Treating overweight children may be more difficult when parents themselves do not correctly recognize their child’s weight status (Camell, Edwards, Croker, Boniface, & Wardle, 2005 Boniface, & Wardle, 2005). While it is a commonly held belief in some cultures that overweight children are healthy, incorrectly assessing overweight in very young children results in unfavorable weight development throughout childhood (Kroje, Struthman, & Gunther, 2006). This is due to the increased likelihood that parents may not take the condition of obesity in their child as being serious, or they may fail to seek or accept professional help in correcting the problem …

Long Term Weight Variability In Adults Of Adventist Health Study 1 And 2, Namgyal Lhawang Kyulo

Loma Linda University Electronic Theses, Dissertations & Projects

Background: The effect of overweight and obesity on the risk of fatal disease tends to attenuate with age. One plausible explanation is that a proportion of elderly people in the ideal weight category (19 to 25 kg/m ) experienced disease-related weight loss - an effect that will attenuate health risk related to overweight and obesity. One potential approach to controlling for this bias would be to examine fluctuations in weight during the adult lifespan by considering multiple measures of weight or recall of body weight during adulthood. Some of these measures are available in the Adventist Health Study cohorts and …
