Effects Of Functional Appliances On Pharyngeal Airway Dimensions: A Cone Beam Computed Tomography Study, Melissa K. Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Functional appliances are intended to correct by incremental advancement of the mandible for correction of skeletal Class 11 relationships. Similar in design to functional appliances, mandibular advancing devices (MAD) are used for obstructive sleep apnea (OSA) patients as they increase the size of the airway by drawing the tongue and soft palate forwards, and thus maintain its patency during sleep. It has been shown that significant increases in airway dimensions and decreases in airway resistance were gained in OSA patients while evaluated with a MAD in place. This retrospective study evaluated volumetric, cross-sectional area and linear changes in the …

Longitudinal Association Of Sleep-Disordered Breathing And Nondipping Of Nocturnal Blood Pressure In The Wisconsin Sleep Cohort Study, Khin Mae Hla, Terry Young, Laurel Finn, Paul E. Peppard, Mariana Szklo-Coxe, Maryan Stubbs

Community & Environmental Health Faculty Publications

Study objectives: The association of sleep-disordered breathing (SDB) and blunting of normal nocturnal lowering of blood pressure (BP) (nondipping) has only been examined cross-sectionally. The purpose of this study is to investigate whether SDB is prospectively associated with nondipping.

Methods: The longitudinal association between SDB and incident nondipping was examined in a subsample of 328 adults enrolled in the Wisconsin Sleep Cohort Study who completed 2 or more 24-hour ambulatory BP studies over an average of 7.2 years of follow-up. SDB identified by baseline in-laboratory polysomnography was defined by apnea-hypopnea index (AHI) categories. Systolic and diastolic nondipping was defined by …

Children With Autism: Sleep Problems And Predictors Of Maternal Stress, Cindy Y. Nam

Loma Linda University Electronic Theses, Dissertations & Projects

Research examining the impact of children’s autism and the sleep problems frequently associated with the disorder on parents’ stress has been quite limited. Studies have been constrained by methodological problems, including small sample sizes and the examination of children of autism within larger groups of children with a range of developmental disabilities. Typically, diagnostic criteria used to select children for an autism study is not indicated and no measure of the severity of children’s symptomology is included. The present investigation was designed to examine children’s autism symptomology and parents’ reports of their children’s sleep problems as well as the parents …

Depression: Relationships To Sleep Paralysis And Other Sleep Disturbances In A Community Sample, Mariana Szklo-Coxe, Terry Young, Laurel Finn, Emmanuel Mignot

Community & Environmental Health Faculty Publications

Sleep disturbances are important correlates of depression, with epidemiologic research heretofore focused on insomnia and sleepiness. This epidemiologic study’s aim was to investigate, in a community sample, depression’s relationships to other sleep disturbances: sleep paralysis (SP), hypnagogic/hypnopompic hallucinations (HH), cataplexy – considered rapid eye movement-related disturbances – and automatic behavior (AB). Although typical of narcolepsy, these disturbances are prevalent, albeit under-studied, in the population. Cross-sectional analyses (1998–2002), based on Wisconsin Sleep Cohort Study population-based data from 866 participants (mean age 54, 53% male), examined: depression (Zung Self-Rating Depression Scale), trait anxiety (Spielberger State-Trait Anxiety Inventory, STAI-T ≥ 75th percentile), and …

The Validation Of An Existing Sleep Apnea Questionnaire And Its Application To Clinical Orthodontics, Jeffery C. Biggs

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to validate a sleep apnea questionnaire from the Loma Linda University Sleep Disorders Center, and then to utilize the questionnaire in order to identify potential sleep apnea patients from a pre-orthodontic patient sample. Study patients were selected from the Loma Linda University Sleep Disorders Center and the Loma Linda University Orthodontics Clinic, both in Loma Linda, California, USA.

Methods: The study sample represented all of the patients initially examined from 1996 through 1998 who were age 8-15 years old at the time of the initial exam. Validation of the questionnaire was based on responses …

Tyrosine As A Countermeasure To Performance Decrement During Sleep Loss, Douglas A. Wiegmann, David F. Neri, Robert R. Stanny, Scott Shappell, Andrew M. Mccardie, David L. Mckay

Publications

The fatigue and cognitive performance deficits associated with sleep loss and stress have motivated the search for effective nonpharmacological countermeasures. The purpose of the present study was to examine the potential behavioral effects of tyrosine, an amino-acid presursor to dopamine and norepinephrine, during an episode of continuous nighttime work involving one night of sleep loss.

The Effect Of Natural Measures To Aid In Sleep As Compared With The Use Of Flurazepam 30 Milligrams As Seen In The Hospitalized Male Patient, Myra Ladd Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Sleep is necessary for physical and psychological restoration of the body. Studies indicate that tissue repair is augmented during sleep, showing that rates of protein synthesis and of mitotic division are higher at times of rest and sleep. Studies evaluating sleep-deprived subjects reveal that after loss of normal sleep, some types of memory and learning processes are impaired. These subjects generally become anxious and irritable, especially after loss of dreaming sleep.

Sleeping medications have been implicated by observers and researchers to be a cause of altered sleep patterns. These medications not only disrupt normal sleep cycles, but their continued use …

A Study Of The Physiological And Mental Effects Of Various Shift Patterns On Registered Nurses, Carolyn Taylor Smith

Loma Linda University Electronic Theses, Dissertations & Projects

The effects of shift work on circadian I an rhythms has become a subject of great Interest to many industries, hospitals, and sleep researchers. More and more recognition is being given to the results of these studies, especially the possible adverse effects on those working the night shift or a shift they are unable to adapt to adequately. Only a few of these studies, however, have been conducted on registered nurses, a major group involved with shift work.

The purpose of the present study was to investigate the effects on nurses working the a.m. shift (7 a.m. to 3:30 p.m.), …

The Effect Of 72 Consecutive Hours In The Coronary Care Unit On The Night Sleep Of 10 Patients Age 65 And Older, Eugenia J. Creason

Loma Linda University Electronic Theses, Dissertations & Projects

The prevalence of heart disease in the population over age 65 has contributed to the increasing number of aged patients hospitalized in critical care units (Gsell, 1977). Changes which occur in the process of aging and in cardiac disease should be considered when providing nursing care to these patients. A disturbance in the sleep wakefulness cycle resulting in a decrease of restorative sleep is a major change occurring at age 65 and after (Feinberg, 1967). The cardiac patient finds that it takes longer to go to sleep, and then awakens often during the night (Karacan et al., 1969).

Relationship Between Sleep Deprivation And Postpartum Depression, Janet Wagner

Loma Linda University Electronic Theses, Dissertations & Projects

Postpartum depression was thought to be an important component of maternity blues and was the factor explored in this study. Sleep was hypothesized as a factor affecting either the occurrence or severity of postpartum depression. Hence, the purpose of this study was to determine the relationship between sleep deprivation and postpartum depression.

Twenty patients were interviewed one to three weeks prior to their expected dates of delivery. The Minnesota Multiphasic Personality Inventory Depression scale was administered during the interview and each patient kept a record of her hours of sleep during the following week. Each patient again kept a record …
