Illness Cognitions And Coping Self-Efficacy In Depression Among Persons With Low Vision., Bonnie A Sturrock, Jing Xie, Edith E Holloway, Mark Hegel, Robin J. Casten, David Mellor, Eva Fenwick, Gwyneth Rees

Department of Psychiatry and Human Behavior Faculty Papers

PURPOSE: To investigate the mediating role of coping self-efficacy (CSE) between two types of illness cognitions (i.e., acceptance and helplessness) and depressive symptoms in persons with low vision.

METHODS: This was a single-group, cross-sectional study. Patients with visual acuity < 6/12 in the better eye and at least minimal depressive symptoms (≥5 on the Patient Health Questionnaire-9 [PHQ-9]) were recruited from vision rehabilitation services and participated in telephone-administered structured interviews at one time point. Measures were the PHQ-9, CSE Scale, and Illness Cognition Questionnaire. Structural equation modeling (SEM) devised the causal flow of illness cognitions and their observed indirect effects on depressive symptoms via the CSE mediators: problem focused, emotion focused, and social support.

RESULTS: The study comprised 163 patients (mean age 62 years; 61% female), most with age-related macular degeneration (26%) and moderate vision impairment (44%, <6/18-6/60). Structural equation modeling indices indicated a perfect fit (χ2 < 0.001, P = 1.00), accounting for 55% of the variance in depressive symptoms. Lower levels of acceptance and higher levels of helplessness illness cognitions were associated with lower self-efficacy in problem-focused coping (β = 0.38, P < 0.001, β = -0.28, P < 0.01, respectively), which in turn was associated with greater depressive symptom severity (β = -0.54, P < 0.001).

CONCLUSIONS: Lack of acceptance and greater helplessness relating to low vision led to a lack of perceived capability to engage in problem-focused coping, which in turn promoted depressive symptoms. Third-wave cognitive-behavioral treatments that focus on acceptance may be …

Journal of Asian Midwives (JAM)

Midwives have had a major presence in the Chilean Health System since 1834, just a few years after the country’s independence from Spain. Since then, the professionalization and expertise achieved by professional midwives has resulted in considerable improvement in women’s sexual and reproductive health.

Today, the maternal Mortality Ratio is rated the second lowest in the Americas (16 deaths per 100,000 live births), and midwives take care of virtually all deliveries in the public system, in both rural and urban women’s health care units (99.8%). Such figures have been attained after many years of hard work; and, as a consequence, …

Partner Interfering Behaviors Affecting Cancer Quality Of Life, Ann L. Coker, Diane R. Follingstad, Lisandra S. Garcia, Heather M. Bush

Obstetrics and Gynecology Faculty Publications

Objective: Because partners are an important and unpaid resource in cancer care, understanding how destructive, controlling or interfering partner behaviors influence women's cancer care may be particularly relevant for health care providers seeking to provide cancer care and enhance recovery. Using a new measure of partner interfering behaviors in cancer care (PIB-C), we investigated whether women with a recent cancer diagnosis who additionally endorsed any PIB-C would report (a) more symptoms of depression and stress, and (b) lower Functional Assessment of Cancer Therapy (FACT-G) and lower Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-SP) scale scores indicating poorer quality of …

Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay

Loma Linda University Electronic Theses, Dissertations & Projects

Touted among the major achievements in the diagnosis and management of Prostate cancer (PCa) in the past few decades has been, the dramatic decline of men with advanced/metastatic PCa at diagnosis coupled with a significant improvement ( >90%) in the five and ten year survival rates of the disease. Non-palpable PCa (potentially clinically treatable disease) now accounts for 70-80% of all newly diagnosed cases of PCa. Preceding these changes by about a decade was the introduction of Prostatic Specific Antigen (PSA) into clinical practice; first as biomarker for monitoring response to therapy and subsequently as a complementary screening tool. It …

Mechanism Of Chimeric Vaccine Mediated Immune Suppression Of Human Dendritic Cells, Jacques Christian Mbongue

Loma Linda University Electronic Theses, Dissertations & Projects

Type 1 diabetes mellitus is a chronic inflammatory disease in which insulin producing β-cells of the pancreatic islets are killed by autoreactive cells of the immune system in response to a loss of tolerance. Dendritic cells (DC) interact predominantly with naïve T cells to regulate the delicate balance between immunity and tolerance required to maintain immunological homeostasis. In this dissertation, immature human dendritic cells (iDC) were inoculated with a chimeric fusion protein vaccine containing the pancreatic β-cell auto-antigen proinsulin linked to a mucosal adjuvant the cholera toxin B subunit (CTB-INS). Proteomic analysis of vaccine inoculated DCs revealed strong up-regulation of …

The Role Of Collagen Interacting Proteins In The Pathogenesis Of Filifactor Alocis, Ozioma Salomey Chioma

Loma Linda University Electronic Theses, Dissertations & Projects

Filifactor alocis is a Gram-positive, asaccharolytic; obligate anaerobe that has emerged as a potential periodontal pathogen due to its presence in high numbers in patients who have periodontal disease and least detection in healthy individuals (Kumar et al., 2003, Kumar et al., 2006, Wade, 2011). There is compelling evidence in the literature that demonstrates that F. alocis has virulence properties that may play an important role in infection-induced periodontitis (Abusleme et al., 2013, Griffen et al., 2012, Hutter et al., 2003, Khader et al., 2006, Siqueira and Rocas, 2003, Siqueira et al., 2009). However, there is a gap in our …

Effects Of Neonatal Dexamethasone On The Maturation And Endowment Of Cardiomyocytes, Maresha Gay

Loma Linda University Electronic Theses, Dissertations & Projects

Each year 1 in 9 infants are born preterm in the United States. Preterm infants have a host of complications associated with prematurity, including respiratory distress syndrome. Dexamethasone, a synthetic glucocorticoid is the ‘gold standard’ intervention in the treatment of preterm infants and mothers at risk of preterm birth because it promotes organ maturation, particularly the lungs and aids in surfactant production. However, a growing body of evidence suggests perinatal dexamethasone exposure is associated with health consequences later in life including increased risk of cardiovascular disease. Cardiomyocytes are the functional unit of the heart and are unique in that they …

Mechanisms Of Post-Hemorrhagic Hydrocephalus After Germinal Matrix Hemorrhage, Damon William Klebe

Loma Linda University Electronic Theses, Dissertations & Projects

The inherently fragile vasculature of the germinal matrix is susceptible to rupture, possibly as a result of hemodynamic and cardiorespiratory instability associated with prematurity. Germinal matrix hemorrhage is a leading cause of morbidity and mortality in preterm and/or very low birthweight infants, and post-hemorrhagic hydrocephalus is major consequence of severe grade hemorrhages. Chronic post-hemorrhagic hydrocephalus treatment involves surgical insertion of shunts, which are costly and prone to complications. Thus, a safe non-invasive therapeutic approach towards post-hemorrhagic hydrocephalus clinical management would significantly improve the quality of life for this patient population. Thrombin, cerebroventricular blood clots, and iron have been identified as …

Developmental Pedagogy In Marriage And Family Therapy Education, Christopher Russell Hoff

Loma Linda University Electronic Theses, Dissertations & Projects

New practice domains are opening up for practitioners of family therapy in the medical, organizational, and human relations fields. In this new environment, family therapy educators and supervisors are required to cross the epistemological spaces of scientist-practitioner, postmodernism, and critical theory. These new possibilities require that family therapist educators become comfortable moving between multiple epistemologies. This poses increasing challenges that will require a hybridization of knowledge and practice approaches in MFT education. Through focus groups consisting of 34 participants, all of who were in their first quarter of a Master’s degree program in Marriage and Family Therapy. We found a …

Influence Of Low Temperature Degradation On Microstructural Integrity Of Zirconia Dental Implants, Mona Monzavi Rahimi

Loma Linda University Electronic Theses, Dissertations & Projects

Zirconia dental implants have become more popular in the field of implant dentistry. However, concerns have been raised regarding low temperature degradation and its influence on phase stability and micro-structural integrity in terms of increased micro-crack formation. In the case of dental implants, this could possibly result in delamination and interference with bone to implant contact and eventually lead to loss of integration and failure. Nevertheless, no study has reported the effects on commercially available Zirconia dental implants. The primary aims of this study was to determine if there is a correlation between ageing duration and 1) depth of tetragonal-monoclinic …

Exploring Factors In The Relationship Balance Assessment, Thomas B. Luttrell

Loma Linda University Electronic Theses, Dissertations & Projects

While studies have highlighted the role of gendered power in relationships, many assumptions have not been quantitatively tested due to a lack of measures for power. This study uses exploratory factor analysis to construct a dyadic assessment of relative power and equality in relationships. This assessment would be useful for research and for clinical work with couples to help raise awareness of the balance of power in their relationship. Equality is defined as a mutual process in which both partners demonstrate that they hold equal value in the relationship, whereas inequality is when there is a relative imbalance of value …

Role Of Protein Kinase G In Regulating Vascular Tone In Hypoxic Ovine Cerebral Arteries, Richard Burdette Thorpe

Loma Linda University Electronic Theses, Dissertations & Projects

Nitric oxide (NO) and its precursors have been used clinically to induce vasorelaxation long before the specific mechanism of how this operates was understood. With the discovery in 1977 of the influence of NO on guanylate cyclase, and the subsequent elucidation of the NO pathway, the role of cyclic guanidine monophosphate (cGMP)-dependent protein kinase (PKG) has been shown to be the main mediator of NO-induced vasorelaxation. Less well understood is the behavior of this pathway in conditions of long term hypoxia (LTH). It was later shown that LTH attenuates the ability of PKG to mediate vasorelaxation. How this operates is …
