BACKGROUND: The order and magnitude of pathologic processes in Alzheimer's disease are not well understood, partly because the disease develops over many years. Autosomal dominant Alzheimer's disease has a predictable age at onset and provides an opportunity to determine the sequence and magnitude of pathologic changes that culminate in symptomatic disease. METHODS: In this prospective, longitudinal study, we analyzed data from 128 participants who underwent baseline clinical and cognitive assessments, brain imaging, and cerebrospinal fluid (CSF) and blood tests. We used the participant's age at baseline assessment and the parent's age at the onset of symptoms of Alzheimer's disease to …

Intense Physical Activity Is Associated With Cognitive Performance In The Elderly, Belinda Brown, Jeremiah Peiffer, Hamid Sohrabi, Alinda Mondal, Veer Bala Gupta, Stephanie Rainey-Smith, Kevin Taddei, S Burnham, K Ellis, C Szoeke, C L Masters, D Ames, C Rowe, Ralph Martins

Research outputs 2012

Numerous studies have reported positive impacts of physical activity on cognitive function. However, the majority of these studies have utilised physical activity questionnaires or surveys, thus results may have been influenced by reporting biases. Through the objective measurement of routine levels of physical activity via actigraphy, we report a significant association between intensity, but not volume, of physical activity and cognitive functioning. A cohort of 217 participants (aged 60-89 years) wore an actigraphy unit for 7 consecutive days and underwent comprehensive neuropsychological assessment. The cohort was stratified into tertiles based on physical activity intensity. Compared with individuals in the lowest …

Olfactory Discrimination Predicts Cognitive Decline Among Community-Dwelling Older Adults, Hamid Sohrabi, Kristyn Bates, Mg Weinborn, A N Johnston, A Bahramian, Kevin Taddei, Simon Laws, Mark Rodrigues, Michael Morici, Matthew Howard, Georgia Martins, A Mackay-Sim, Se Gandy, Ralph Martins

Research outputs 2012

The presence of olfactory dysfunction in individuals at higher risk of Alzheimer's disease has significant diagnostic and screening implications for preventive and ameliorative drug trials. Olfactory threshold, discrimination and identification can be reliably recorded in the early stages of neurodegenerative diseases. The current study has examined the ability of various olfactory functions in predicting cognitive decline in a community-dwelling sample. A group of 308 participants, aged 46-86 years old, were recruited for this study. After 3 years of follow-up, participants were divided into cognitively declined and non-declined groups based on their performance on a neuropsychological battery. Assessment of olfactory functions …

Kimmel Cancer Center Faculty Papers

INTRODUCTION:

The incidence of melanoma is dramatically increasing worldwide. We hypothesized that the ratio of metastatic to examined lymph node ratio (LNR) would be the most important prognostic factor for stage III patients.

METHODS:

We retrospectively reviewed our institutional database of melanoma patients and identified 168 patients who underwent lymph node dissection (LND) for stage III disease between 1993 and 2007. Patients were divided into three groups based on LNR (≤10%, n = 93; 10-≤25%, n = 45; and >25%, n = 30). Univariate and multivariate analysis was performed using Cox proportional hazards model.

RESULTS:

The median survival time of …

Development Of Abbreviated Measures To Assess Patient Trust In A Physician, A Health Insurer, And The Medical Profession, Elizabeth Dugan, Felicia Trachtenberg, Mark Hall

Elizabeth Dugan

BACKGROUND: Despite the recent proliferation in research on patient trust, it is seldom a primary outcome, and is often a peripheral area of interest. The length of our original scales to measure trust may limit their use because of the practical needs to minimize both respondent burden and research cost. The objective of this study was to develop three abbreviated scales to measure trust in: (1) a physician, (2) a health insurer, and (3) the medical profession. METHODS: Data from two samples were used. The first was a telephone survey of English-speaking adults in the United States (N = 1117) …

Patient Education About Anticoagulant Medication: Is Narrative Evidence Or Statistical Evidence More Effective?, Kathleen Mazor, Joann Baril, Elizabeth Dugan, Frederick Spencer, Pamela Burgwinkle, Jerry Gurwitz

Elizabeth Dugan

OBJECTIVE: To determine the relative impact of incorporating narrative evidence, statistical evidence or both into patient education about warfarin, a widely used oral anticoagulant medication.

METHODS: 600 patients receiving anticoagulant therapy were randomly assigned to view one of three versions of a video depicting a physician-patient encounter where anticoagulation treatment was discussed, or usual care (no video). The videos differed in whether the physician used narrative evidence (patient anecdotes), statistical evidence, or both to highlight key information. 317 patients completed both the baseline and post-test questionnaires. Questions assessed knowledge, beliefs and adherence to medication and laboratory monitoring regimens.

Relationship Between Vancomycin Trough Concentrations And Nephrotoxicity: A Prospective Multicenter Trial, John A. Bosso, Jean Nappi, Celeste Rudisill, Marlea Wellein, P Brandon Bookstaver, Jenna Swindler, Patrick D. Mauldin

Faculty Publications

Several single-center studies have suggested that higher doses of vancomycin, aimed at producing trough concentrations of >15 mg/liter, are associated with increased risk of nephrotoxicity. We prospectively assessed the relative incidence of nephrotoxicity in relation to trough concentration in patients with documented methicillin-resistant Staphylococcus aureus (MRSA) infections at seven hospitals throughout South Carolina. Adult patients receiving vancomycin for at least 72 h with at least one vancomycin trough concentration determined under steady-state conditions were prospectively studied. The relationship between vancomycin trough concentrations of >15 mg/ml and the occurrence of nephrotoxicity was assessed using univariate and multivariate analyses, controlling for age, …

Becoming A Registered Nurse: The Nurse Extern Experience, K. Starr, Virginia Conley

Virginia M. Conley

Little is known about the perceptions of nursing students externing in newly developed hospital-based programs that focus on socialization and transition to the registered nurse (RN) role rather than on institutional recruitment and retention goals. This qualitative study explored student nurse externs' expectations, experiences, and benefits of participation in a student-focused externship program. Externs wanted to gain experience with skills and learn what it was like to be an RN. Goals were met or exceeded by becoming comfortable in the externship role, growing in skill performance and confidence, and becoming members of the healthcare team. The experience fostered growth from …

Informational Needs Of Caregivers Of Terminal Patients In A Rural State, Virginia Conley, M. Burman

Virginia M. Conley

Home care of a terminally ill family member is stressful, especially in rural areas. This qualitative study sought to determine informational needs of rural caregivers and how that information is obtained. Although most caregivers stated satisfaction with available information, mostly obtained from physicians and nurses, their behavior belied their satisfaction. Assertive and self-reliant, they used informal communications rather than written information to meet most of their needs. Approaches home care nurses can use to help caregivers obtain important information are presented.

Patient And Parent/Guardian Perspectives On The Health Care Of Adults With Mental Retardation, Sarah Voss Horrell, William Maclean, Virginia Conley

Virginia M. Conley

Individuals with mental retardation and their parents/guardians have long been neglected in health care research. In this study we used a qualitative methodology to describe the experiences adults with mental retardation and their parents/guardians have with the delivery of primary care services. Semi-structured in-depth interviews were conducted with 12 adults who had mental retardation and 9 parents/guardians. The grounded theory approach was utilized to guide data collection and analysis. Findings suggest an overall positive experience with primary care services. Unique themes were identified that distinguished parent/guardian experiences from those of adults with mental retardation, who focused on immediate, concrete issues …

Patient Preferences And Discharge Planning Transitions, Diane Huber, E. Mcclelland

Diane Huber

Discharge planning is an urgently needed nursing intervention. The purpose of this article is to investigate the importance of patient and family preferences and participation for discharge planning and to describe the pilot testing of an instrument to measure patient preferences for discharge planning. The results identified a lack of congruence between patients' and caregivers' preferences, suggesting the need to assess both patients' and families' preferences early and incorporate this in discharge planning that begins at admission to a hospital. The instrument, Patient Participation Preferences Assessment (PPPA), is shown to be a useful, reliable, and valid instrument that can be …

Department of Medical Oncology Faculty Papers

Studies of haploidentical hematopoietic stem cell transplantation (HSCT) have identified threshold doses of T cells below which severe GVHD is usually absent. However, little is known regarding optimal T-cell dosing as it relates to engraftment, immune reconstitution, and relapse. To begin to address this question, we developed a 2-step myeloablative approach to haploidentical HSCT in which 27 patients conditioned with total body irradiation (TBI) were given a fixed dose of donor T cells (HSCT step 1), followed by cyclophosphamide (CY) for T-cell tolerization. A CD34-selected HSC product (HSCT step 2) was infused after CY. A dose of 2 × 10(8)/kg …

The Willingness Of Family Members Of Critically Ill Adults To Learn The Coping Technique Of Imagery, D. Schweer, L. Hart, O. Glick, Paula Mobily

Paula Mobily

Critical care nurses face the challenge of helping anxious families cope with the critical illness of one of their members. The purposes of this exploratory descriptive pilot study were to identify whether adult family members of surgical intensive care unit (SICU) patients were willing and able to learn imagery during the time of their family member's critical illness, and which factors facilitate the learning. Of the 139 persons invited, 26 (18.7%) indicated willingness to participate, but only 10 participants completed both learning sessions. All 10 subjects achieved increased relaxation with the imaging. Facilitators of their learning were the quiet environment, …

Infant And Preschool Well-Child Care: Master's- And Nonmaster's-Prepared Pediatric Nurse Practitioners, J. Glascock, C. Webster-Stratton, Ann Mccarthy

Ann Marie McCarthy

The nursing and medical literature reveals considerable debate over whether graduate or continuing education is the appropriate level for nurse practitioner preparation. These arguments have been rhetorical since the research literature lacks data on the scope of practice of master's- and nonmaster's-prepared nurse practitioners. The purpose of this study was to examine possible differences between the two types of practitioners in one area--well-child care provided by pediatric nurse practitioners (PNPs). A total of 236 master's- and nonmaster's-prepared PNPs completed a background questionnaire and checklists of nursing activities involving infant and preschool well-child care. Analysis of study results showed that master's …

The Early Bird Does Not Get The Worm: Time-Of-Day Effects On College Students' Basic Cognitive Processing, P. Allen, J. Grabbe, Ann Mccarthy, A. Bush, B. Wallace

Ann Marie McCarthy

We conducted a neuropsychological and cognitive assessment study to determine whether time of day affects cognitive performance. We measured executive control (fluency), processing speed, semantic memory, and episodic memory performance. We followed 56 students across 3 different times of day, testing performance on vocabulary, fluency, processing speed, and episodic memory. Results showed an advantage for fluency and digit symbol task performance in the afternoon and evening testing times relative to morning testing (regardless of testing order), but that time of day did not affect semantic or episodic memory performance. These results suggest that optimal executive functioning and processing speed may …
