Contrasting Roles Of Neural Firing Rate And Local Field Potentials In Human Memory, A. Ekstrom, Indre Viskontas, M. Kahana, J. Jacobs, K. Upchurch, S. Bookheimer, I. Fried

Psychology

Recording the activity of neurons is a mainstay of animal memory research, while human recordings are generally limited to the activity of large ensembles of cells. The relationship between ensemble activity and neural firing rate during declarative memory processes, however, remains unclear. We recorded neurons and local field potentials (LFPs) simultaneously from the same sites in the human hippocampus and entorhinal cortex (ERC) in patients with implanted intracranial electrodes during a virtual taxi-driver task that also included a memory retrieval component. Neurons increased their firing rate in response to specific passengers or landmarks both during navigation and retrieval. Although we …

Care Patterns And Outcomes For Hospitalized Patients With Diabetes In Nevada, Jay J. Shen

Nevada Journal of Public Health

This study demonstrates substantial differences between Nevada and the national average in patterns of hospital based care in patients with type 2 diabetes. Diabetic patients in Nevada are more likely to be hospitalized through the emergency department, and more likely to be admitted for a condition related to diabetes. Moreover, in Nevada, Medicaid and uninsured patients with diabetes are more likely to experience adverse outcomes then their privately insured counterparts. These differences may be primarily reflective of variances in access to ambulatory care, care seeking behavior, and availability of health services and facilities. Policies promoting expansion of health care benefits …

The Status Of Childhood Lead Poisoning And Prevention In Nevada, Usa, Anne Rothweiler, Elena E. Cabb, Shawn Gerstenberger

Environmental & Global Health Faculty Research

One of the first steps in addressing the problem of childhood lead poisoning is to identify the possible sources of exposure in specific communities and target high-risk populations with appropriate interventions. Due to several factors, such as lack of funding and lack of blood lead reporting, little information exists regarding the occurrence of childhood lead poisoning and the prevalence of potential exposure sources in the state of Nevada. Following the recent establishment of a Nevada-based Lead Poisoning Program, we compiled the most current information available on Nevadans, and use this knowledge to suggest future research objectives and outreach activities for …

Contributing Towards Efforts To Abandon Female Genital Mutilation/Cutting In Kenya: A Situation Analysis, Humphres Evelia, Maryam Sheikh Abdi, Carolyne Njue, Ian Askew

Reproductive Health

The Kenyan Ministry of Gender, Sports, Culture and Social Services, with support from UNFPA/Kenya, commissioned the Population Council to conduct a situation analysis of female genital mutilation/cutting (FGM/C) programs in Kenya, with the overall objective of documenting the current status of and trends in FGM/C programming and to help identify crucial elements that need to be prioritized for support. Results show marked declines in prevalence nationally between generations, suggesting a decline in the practice as well as trends toward “medicalization” in recent years. The practice still continues for different reasons, such as rite of passage, for marriageability, controlling sexuality, religious …

Episiotomy And Obstetric Trauma In Nevada: Evidence From Linked Hospital Discharge And Birth Data, Gulzar H. Shah, Joseph A. Greenway, Wei Yang

Nevada Journal of Public Health

Based on the perception that episiotomy prevents obstetric trauma, the procedure is liberally performed in U.S. Hospitals. Using linked Nevada Birth Registry and Nevada Impatient Hospital Discharges (2000 to 2005), we applied descriptive analyses and logistic regression to examine the status of Nevada episiotomy practice and its impact on birth trauma for mothers. Of 106,461 vaginal live births, 26,383 (24.8%) episiotomies were conducted. Obstetric trauma rate declined from 5.2% of vaginal deliveries in 2000 to 4.4% in 2005. After statistically controlling for the effect of other risk factors, zero parity, episiotomy, other instrument assisted deliveries, non-MDs as birth attendants, rural …

Recognition Of Depression In Primary Care Settings: The Influence Of Patient Age And Gender On Patient Care, Kelly Marie Monette

All-Inclusive List of Electronic Theses and Dissertations

Depression is a common condition that is often poorly detected in primary care medical settings. The elderly often fail to receive appropriate attention to their mental health needs, possibly due to physician's interpretation of physical and emotional changes as part of the normal aging process. The purpose of this study was to explore physicians' identification of depression and to determine whether age-related factors and gender impact recommendations for patient care. The respondents were full-time primary care physicians (N = 46; 63% male) who were randomly selected from a national listing of family medicine practitioners and primary care physicians (family medicine, …

Depression, Sensation Seeking, And Maternal Smoking As Predictors Of Adolescent Cigarette Smoking, Judy Van De Venne, Kay Bradford, Catherine A. Martin, Megan Cox, Hatim A. Omar

Family Sciences Faculty Publications

The purpose of this study was to examine maternal and adolescent depression, maternal and teen sensation seeking, and maternal smoking, and their associations with adolescent smoking. Data were collected from a sample of 47 male and 66 female adolescents (ages 11-18 years) and their mothers from three different health clinics. The findings indicated that maternal sensation seeking was linked indirectly with adolescent smoking through teen sensation seeking, both of which were significantly associated with teen smoking (β = 0.29, p < 0.001 and β = 0.32, p < 0.001, respectively). Teen depression was associated positively with teen smoking (β = 0.24, p < 0.01) when controlling for sensation seeking behaviors. Maternal smoking was also directly linked to adolescent smoking (β = 0.20, p < 0.05). These findings underscore a potentially important role of sensation seeking in the origins of adolescent smoking, and clarify pathways of influence with regard to maternal attitudes and behaviors in subsequent teenage nicotine use.

L’Imagination Du Corps Greffé : Filtres Bilingues, Mireille Rosello

Présence Francophone: Revue internationale de langue et de littérature

Contemporary narratives featuring organ transplants speak of a painful but also life-saving contact when the “donor” body is African and the receiving body is European. At this point the surgical operation and that of the imagination assume a whole other dimension, as the inequality and interdependence of these two bodies invite the reader to re-imagine the links between the concept of the “body,” on the one hand, and culture and language, on the other. This article looks at the transplanted body as an imagining machine capable of articulating a vision of itself different from the one that words impose upon …

Using The Outcome Questionnaire 45.2 In Obesity Treatment, Adam L. Arechiga

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: The purpose of this study was to determine if the Outcome Questionnaire 45.2 (OQ-45) can be used in the treatment of obesity to predict participant dropout and initial treatment success, in terms of weight loss (Lambert et. al, 2002a). The OQ-45 has been used with success to predict dropout from psychotherapy in clinical populations. It was hypothesized that higher pretreatment OQ-45 scores would be associated with less program completion and less weight loss by the end of treatment.

Method: The study employed a non-experimental time series design. Seventy-eight participants were recruited from the three local obesity treatment programs, which …

Americans' Attitudes Toward Euthanasia And Physician-Assisted Suicide, 1936-2002, Jen Allen, Sonia Chavez, Sara Desimone, Debbie Howard, Keadron Johnson, Lucinda Lapierr, Darrel Montero, Jerry Sanders

The Journal of Sociology & Social Welfare

Public opinion polls conducted from 1936 to 2002 found that Americans support both euthanasia and physician-assisted suicide. Although public opinion regarding end-oflife decisions appears to have been influenced by the events of the times, Americans have consistently favored the freedom to end one's life when the perceived quality of life has significantly diminished, either by one's own hand or with the assistance of a physician. This paper indicates that existing policy regarding euthanasia and physician-assisted suicide conflicts with the American public's attitudes regarding the matter, as well as examines implications for social workers who serve clients facing end-of-life decisions.

Low Doses Of Memantine Disrupt Memory In Adult Rats, Catherine Creeley, David Wozniak, Joanne Labruyere, George Taylor, John Olney

Psychology Faculty Works

Memantine, a drug recently approved for treatment of Alzheimer’s disease, has been characterized as a unique NMDA antagonist that confers protection against excitotoxic neurodegeneration without the serious side effects that other NMDA antagonists are known to cause. In the present study, we determined what dose of memantine is required to protect the adult rat brain against an NMDA receptor-mediated excitotoxic process and then tested that dose and a range of lower doses to determine whether the drug in this dose range is associated with significant side effects. Consistent with previous research, we found that memantine confers a neuroprotective effect beginning …

Few studies have examined the outcomes for Hispanic men with prostate carcinoma and incorporated socioeconomic factors in association with race/ethnicity in affecting survival, adjusting for factors on cancer stage, grade, comorbidity, and treatment.

METHODS

We studied a population-based cohort of 61,228 men diagnosed with local or regional stage prostate carcinoma at age 65 years or older between 1992 and 1999 in the 11 SEER (Surveillance, Epidemiology, and End Results) areas, identified from the SEER-Medicare linked data with up to 11 years of followup.

RESULTS

Low socioeconomic status was significantly associated with decreasing survival in all men with prostate carcinoma. …

Visual-Spatial & Visual-Motor Function In Pediatric Heart Transplant Recipients, Stephanine Dianne Griffone

Loma Linda University Electronic Theses, Dissertations & Projects

Heart surgery is commonly used to repair congenital heart defects and to perform heart transplantation. The associated hypoxia before or during the surgery may cause damage in the parasaggital area of the cerebral cortex, with resulting difficulty during tasks requiring visual-spatial and visual-motor skills. This study compares the performance of children who received a heart transplant during infancy to that of nonclinical children with no medical complications on three visual-motor measures, three visual-spatial measures, and two computerized visual-spatial tasks - a Block Design Matching task and a Mental Rotation task. The children who received a heart transplant achieved significantly lower …

The Reckless Pursuit Of Dominion: A Situational Analysis Of The Nba And Diminishing Player Autonomy, Michael Mccann

Law Faculty Scholarship

This Article examines required genetic testing of NBA players from a situational vantage point, integrating socio-psychological, legal, and ethical analyses. The core argument may be expressed as follows: required genetic testing of NBA players appears consistent with a broader and largely deleterious agenda by the NBA to control players. Since implementation of the rookie wage scale in 1995 through the recent imposition of a paternalistic player dress code, the NBA has increasingly usurped player autonomy. The NBA's capacity to do so largely rests in its adroit manipulation of the situational influences that influence fans and media. For instance, because of …

Differences In Mnemonic Processing By Neurons In The Human Hippocampus And Parahippocampal Regions, Indre Viskontas, B. J. Knowlton, P. N. Steinmetz, I. Fried

Psychology

Different structures within the medial-temporal lobe likely make distinct contributions to declarative memory. In particular, several current psychological and computational models of memory predict that the hippocampus and parahippocampal regions play different roles in the formation and retrieval of declarative memories [e.g., Norman, K. A., & O'Reilly, R. C. Modeling hippocampal and neocortical contributions to recognition memory: A complementary-learning systems approach. Psychological Review, 110, 611-646, 2003]. Here, we examined the neuronal firing patterns in these two regions during recognition memory. Recording directly from neurons in humans, we find that cells in both regions respond to novel stimuli with an increase …

Reproductive Health Update Trainings For Health Workers In North Eastern Province, Garissa, Kenya Ministry Of Health, Population Council

Reproductive Health

The Somali community living in Kenya has practiced the severest form of female genital mutilation/cutting (FGM/C), infibulation, for centuries. To understand the context within which the practice takes place, and how its complications are managed, FRONTIERS undertook a diagnostic study in North Eastern Province and in the Eastleigh area of Nairobi. The study found that the health system is ill equipped to serve women who have been cut, and particularly infibulated women who are pregnant and delivering, stemming from an overall weakness in the availability and quality of maternal and neonatal heath services. Specific recommendations could strengthen these services so …

Strategies For Encouraging The Abandonment Of Female Genital Cutting In West Africa: Experiences From Senegal, Burkina Faso, And Mali, Nafissatou J. Diop, Ian Askew

Reproductive Health

This article explores efforts to encourage abandonment of female genital cutting (FGC) in Senegal, Burkina Faso, and Mali. The strategy of encouraging traditional practitioners to stop performing FGC is not effective as community-level support for the practice remains high. Training health staff significantly improved healthcare providers' levels of knowledge about FGC and its complications. Consequently, it was recommended that such training be incorporated into preservice medical training. The use of community-based strategies like the Village Education Program (VEP) showed the most promise, as their multifaceted approach addresses knowledge, attitudes, actions, and communal support in an integrated manner. The way forward …

Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey

Psychology Theses & Dissertations

Currently, a thorough description of the knowledge, skills, abilities, and other personal characteristics (KSAOs) that distinguish an exceptional surgeon does not exist. This knowledge is pertinent to the development of selection, training, and performance assessment methods that can be used to develop high performing surgeons. Expert surgeons from around the country were recruited to participate in an interview to discuss the KSAOs (i.e., the competencies) needed to be exceptional in the field. A smaller number of novice surgeons were also interviewed. The expert interview data were distilled into a competency model that consists of ten competencies and patterns within the …

Coping Processes Of Couples Experiencing Infertility, Brennan Peterson, Christopher R. Newton, Karen H. Rosen, Robert S. Shulman

Psychology Faculty Articles and Research

This study explored the coping processes of couples experiencing infertility. Participants included 420 couples referred for advanced reproductive treatments. Couples were divided into groups based on the frequency of their use of eight coping strategies. Findings suggest that coping processes, which are beneficial to individuals, may be problematic for one's partner. Couples where men used high amounts of distancing, while their partner used low amounts of distancing, reported higher levels of distress when compared to couples in the other groups. Conversely, couples with women who used high amounts of self-controlling coping, when paired with men who used low amounts of …
