Neurology Faculty Publications

BACKGROUND AND PURPOSE: Acid/base and electrolytes could provide clinically valuable information about cerebral infarct core and penumbra. We evaluated associations between acid/base and electrolyte changes and outcomes in 2 rat models of stroke, permanent, and transient middle cerebral artery occlusion.

METHODS: Three-month old Sprague-Dawley rats underwent permanent or transient middle cerebral artery occlusion. Pre- and post-middle cerebral artery occlusion venous samples for permanent and transient models provided pH, carbon dioxide, oxygen, glucose, and electrolyte values of ionized calcium, potassium, and sodium. Multiple regression determined predictors of infarct volume from these values, and Kaplan-Meier curve analyzed morality between permanent and transient …

Differences In Work Environment For Staff As An Explanation For Variation In Central Line Bundle Compliance In Intensive Care Units., Yuna S.H. Lee, Patricia W. Stone, Monika Pogorzelska-Maziarz, Ingrid M. Nembhard

College of Nursing Faculty Papers & Presentations

BACKGROUND: Central line-associated bloodstream infections (CLABSIs) are a common and costly quality problem, and their prevention is a national priority. A decade ago, researchers identified an evidence-based bundle of practices that reduce CLABSIs. Compliance with this bundle remains low in many hospitals.

PURPOSE: The aim of this study was to assess whether differences in core aspects of work environments-workload, quality of relationships, and prioritization of quality-are associated with variation in maximal CLABSI bundle compliance, that is, compliance 95%-100% of the time in intensive care units (ICUs).

METHODOLOGY/APPROACH: A cross-sectional study of hospital medical-surgical ICUs in the United States was done. …

Neonatal Respiratory Distress In The Community Hospital: When To Transport, When To Keep., H. Hein, J. Ely, Maria Lofgren

Maria A Lofgren

Neonatal respiratory distress is a common problem confronting family physicians. Although respiratory distress may represent a benign, self-limited process, it may also be the first sign of sepsis or serious cardiopulmonary disease. Because it is crucial to differentiate the two, we offer a practical approach to the treatment of neonatal respiratory distress at community hospitals. Our method, the Rule of 2 Hours, is based on readily accessible clinical findings. We believe it will help physicians detect babies at risk for serious problems, but will not result in unnecessary referral of neonates that are simply adapting to extrauterine life.

Effects Of Time Of Deoxyribonucleic Acid Microinjection On Gene Detection And In Vitro Development Of Bovine Embryos, Amy Sparks, R. Canseco, C. Russell, J. Johnson, H. Moll, W. Velander, F. Gwazdauskas

Amy E.T. Sparks

In vivo fertilized embryos were surgically collected from superovulated dairy cows to evaluate microinjection on embryo development and utilized the polymerase chain reaction technique for selection of transgenic embryos. Seventy-two percent of the embryos with visible pronuclei or nuclei were microinjected with DNA, and the remaining 28% served as uninjected controls. All embryos were cocultured with bovine oviductal epithelial cells. Mean final development scores of embryos within the same initial cell stage at collection were unaffected by microinjection. After 144 h of culture, 45% of the microinjected embryos developed to the morula or blastocyst stage. The transgene was detected in …

A Placebo-Controlled Randomized Trial Of The Terbutaline Pump For Prevention Of Preterm Delivery, K. Wenstrom, C. Weiner, D. Merrill, Jennifer Niebyl

Jennifer R Niebyl

To determine the efficacy of the terbutaline pump for the prevention of preterm delivery, patients in preterm labor defined by progressive cervical change underwent intravenous magnesium sulfate tocolysis (with or without oral indomethacin, as necessary), and once labor was arrested, were randomized to one of three treatment arms: terbutaline by pump, saline by pump (blinded), or oral terbutaline. If recurrent preterm labor occurred despite maximization of therapy, the treatment arm was determined and therapy was changed; saline pump and oral terbutaline were switched to terbutaline pump, terbutaline pump was switched to oral terbutaline. Patients who continued to labor were readmitted …

Premature Rupture Of The Membranes And Prolonged Latency, J. Johnson, N. Daikoku, Jennifer Niebyl, T. Johnson, V. Khouzami, F. Witter

Jennifer R Niebyl

The aim of this retrospective study in 8320 patients with premature rupture of the membranes (PROM) was to determine the consequences of prolongation of the latent period. Among patients with pregnancies of more than 37 weeks' duration, those with PROM and latent periods of more than 1 day demonstrated an increased incidence of intrapartum fever (IPF), whereas those with latent periods of more than 3 days demonstrated a marked increase in fetal (but not neonatal) deaths. Although IPF and perinatal mortality were more common in preterm pregnancies, neither was found to increase or decrease with prolonged latency, provided differences in …

Randomized Comparative Trial Of Indomethacin And Ritodrine For The Long-Term Treatment Of Preterm Labor, R. Besinger, Jennifer Niebyl, W. Keyes, T. Johnson

Jennifer R Niebyl

A randomized prospective trial was performed to compare the efficacy and safety of ritodrine and indomethacin in the long-term treatment of preterm labor. Forty patients with intact membranes in preterm labor at 23 to 34 weeks' gestation were randomized to receive either intravenous ritodrine or oral indomethacin as the first-line tocolytic agent. Successful intravenous ritodrine therapy was followed by oral terbutaline therapy, and indomethacin-treated patients continued to receive oral indomethacin. Treatment failures were defined as progressive preterm labor or patient intolerance, and these patients were treated with intravenous magnesium sulfate. Ritodrine and indomethacin were equally successful in delaying preterm birth …

Rotary Culture Enhances Pre-Osteoblast Aggregation And Mineralization, S. Facer, R. Zaharias, M. Andracki, J. Lafoon, Stephen Hunter, G. Schneider

Stephen K. Hunter

Three-dimensional environments have been shown to enhance cell aggregation and osteoblast differentiation. Thus, we hypothesized that three-dimensional (3D) growth environments would enhance the mineralization rate of human embryonic palatal mesenchymal (HEPM) pre-osteoblasts. The objective of this study was to investigate the potential use of rotary cell culture systems (RCCS) as a means to enhance the osteogenic potential of pre-osteoblast cells. HEPM cells were cultured in a RCCS to create 3D enviroments. Tissue culture plastic (2D) cultures served as our control. 3D environments promoted three-dimensional aggregate formations. Increased calcium and phosphorus deposition was significantly enhanced three- to 18-fold (P < 0.001) in …

RESULTS: Five hundred ninety-one women were included and 425 completed a diary. The self-report questions had moderate …

Obesity And Outcomes After Sacrocolpopexy, Catherine Bradley, K. Kenton, H. Richter, X. Gao, H. Zyczynski, A. Weber, I. Nygaard

Catherine S. Bradley

OBJECTIVE: The purpose of this study was to compare outcomes after sacrocolpopexy (SC) between obese and healthy-weight women. STUDY DESIGN: Baseline and postoperative data were analyzed from the Colpopexy And Urinary Reduction Efforts (CARE) randomized trial of SC with or without Burch colposuspension in stress continent women with stages II-IV prolapse. Outcomes and complications were compared between obese and healthy-weight women. RESULTS: CARE participants included 74 obese (body mass index >/=30 kg/m(2)), 122 overweight (25-29.9 kg/m(2)), and 125 healthy-weight (18.5-24.9 kg/m(2)) women, and 1 underweight (< 18.5 kg/m(2)) woman. Compared to healthy-weight women, obese women were younger (59.0 +/- 9.9 vs 62.1 +/- 10.3 yrs; P = .04), more likely to have stage II prolapse (25.7% vs 11.2%; P = .01), and had longer operative times (189 +/- 52 vs 169 +/- 58 min; P = .02). Two years after surgery, stress incontinence, prolapse, symptom resolution, and satisfaction did not differ between the obese and healthy-weight groups. CONCLUSION: Most outcomes and complication rates after SC are similar in obese and healthy-weight women.

Apple Juice Improved Non-Cognitive Symptoms In Moderate- To Late-Stage Alzheimer’S Disease In An Open-Label Pilot Study, Ruth Remington, A Chan, A Lepore, E Kotlya, Thomas Shea

Ruth Remington

Preclinical studies demonstrate that apple juice exerts multiple beneficial effects including reduction of central nervous system oxidative damage, suppression of Alzheimer's disease (AD) hallmarks, improved cognitive performance, and organized synaptic signaling. Herein, we initiated an open-label clinical trial in which 21 institutionalized individuals with moderate-to-severe AD consumed 2 4-oz glasses of apple juice daily for 1 month. Participants demonstrated no change in the Dementia Rating Scale, and institutional caregivers reported no change in Alzheimer's Disease Cooperative Study (ADCS)-Activities of Daily Living (ADL) in this brief study. However, caregivers reported an approximate 27% (P < .01) improvement in behavioral and psychotic symptoms associated with dementia as quantified by the Neuropsychiatric Inventory, with the largest changes in anxiety, agitation, and delusion. This pilot study suggests that apple juice may be a useful supplement, perhaps to augment pharmacological approaches, for attenuating the decline in mood that accompanies progression of AD, which may also reduce caregiver burden.

This was a 3-year retrospective cohort study of traumatic injuries in a midwestern pork meatpacking plant. Based on n = 5410 workers, this was a diverse workforce: Caucasian (56.6%), Hispanic (38.9%), African American (2.7%), Asian (1.1%) and Native American (0.8%). There were n = 1655 employees with traumatic injuries during this period. At 6 months of employment, the probability of injury was 33% in the harvest workers who were responsible for slaughter operations. The overall incidence injury rate was 22.76 per 100 full-time employees per year. Women experienced a higher incidence for injury than men. The risk ratio (RR) for …

An Examination Of The Sustainable Adoption Of Whole-Person Care (Wpc), Maria Joseph, D. Laughon, Richard Bogue

Maria (Lindell) Joseph

AIM: This study illustrates how King's theory of goal attainment was used to focus an examination of whole-person care (WPC) and to extend the range of knowledge needed for WPC and nursing practice. BACKGROUND: Leadership implemented a faith-based innovation using continuing education for patient care that incorporates body-mind-spirit and eight principles called CREATION. Three questions arose: (1) Is there an evidence-based framework to determine whether the philosophy supports the discipline of nursing? (2) How extensive is the adoption and application of WPC? (3) Does the model make a difference in the context of nurse-patient interactions and outcomes in support of …

The Influence Of Cognitive-Perceptual Variables On Patterns Of Change Over Time In Rural Midlife And Older Women's Healthy Eating., Bernice C, Yates, Carol H. Pullen, Jonathan Bruce Santo, Linda Boeckner, Patricia A. Hageman, Paul J. Dizona, Susan Noble Walker

Journal Articles: College of Nursing

Although studies demonstrate that dietary interventions for healthy adults can result in beneficial dietary changes, few studies examine when and how people change in response to these interventions, particularly in rural populations. The purpose of this study was to examine patterns of change over time in healthy eating behaviors in midlife and older women in response to a one-year health-promoting intervention, and to examine what predictors (perceived benefits, barriers, self-efficacy, and family support for healthy eating) influence the changes during the intervention and follow-up. Data for this secondary analysis were from the Wellness for Women community-based trial. Women (N = …
