Student Level Ii Fieldwork Failure: Strategies For Intervention., Sharon A. Gutman, Paula Mccreedy, Prudence Heisler

Department of Occupational Therapy Faculty Papers

OBJECTIVE: This report describes how common student communicative and behavioral characteristics that appear to predict the existence of potential problems during Level II fieldwork were identified in order to develop and implement preventative interventions during the academic curriculum at New York University (NYU). RECORD REVIEW: A record review of NYU professional-level occupational therapy students from 1986 to 1995 was completed to identify common factors among students who performed well academically but failed clinical fieldwork. Eight communicative and behavioral characteristics were identified: (a) rigidity of thinking, (b) discomfort with the ambiguity that accompanies clinical reasoning, (c) lack of psychological insight, (d) …

Identifying Global Anatomical Differences: Deformation-Based Morphometry, J Ashburner, C Hutton, R Frackowiak, Ingrid Johnsrude, C Price, K Friston

Brain and Mind Institute Researchers' Publications

The aim of this paper is to illustrate a method for identifying macroscopic anatomical differences among the brains of different populations of subjects. The method involves spatially normalizing the structural MR images of a number of subjects so that they all conform to the same stereotactic space. Multivariate statistics are then applied to the parameters describing the estimated nonlinear deformations that ensue. To illustrate the method, we compared the gross morphometry of male and female subjects. We also assessed brain asymmetry, the effect of handedness, and interactions among these effects.

Triple Dissociation Of Anterior Cingulate, Posterior Cingulate, And Medial Frontal Cortices On Visual Discrimination Tasks Using A Touchscreen Testing Procedure For The Rat., T J Bussey, J L Muir, B J Everitt, T W Robbins

Brain and Mind Institute Researchers' Publications

Four experiments examined effects of quinolinic acid-induced lesions of the anterior cingulate, posterior cingulate, and medial frontal cortices on tests of visual discrimination learning, using a new "touchscreen" testing method for rats. Anterior cingulate cortex lesions impaired acquisition of an 8-pair concurrent discrimination task, whereas posterior cingulate cortex lesions facilitated learning but selectively impaired the late stages of acquisition of a visuospatial conditional discrimination. Medial frontal cortex lesions selectively impaired reversal learning when stimuli were difficult to discriminate; lesions of anterior and posterior cingulate cortex had no effect. These results suggest roles for the anterior cingulate, posterior cingulate, and medial …

Department of Medicine Faculty Papers

BACKGROUND: Treatment of stenosis in saphenous-vein grafts after coronary-artery bypass surgery is a difficult challenge. The purpose of this study was to compare the effects of stent placement with those of balloon angioplasty on clinical and angiographic outcomes in patients with obstructive disease of saphenous-vein grafts.

METHODS: A total of 220 patients with new lesions in aortocoronary-venous bypass grafts were randomly assigned to placement of Palmaz-Schatz stents or standard balloon angioplasty. Coronary angiography was performed during the index procedure and six months later.

RESULTS: As compared with the patients assigned to angioplasty, those assigned to stenting had a higher rate …

Mirizzi Syndrome Type Ii: Is Laparoscopic Cholecystectomy Justified?, D C Desai, R D Smink

Department of Surgery Faculty Papers

Mirizzi syndrome type II is an uncommon cause of obstructive jaundice caused by an inflammatory response to an impacted gallstone in Hartmann's pouch or the cystic duct with a resultant cholecystocholedochal fistula. Two cases of Mirizzi syndrome type II are presented. Clinically only one patient had jaundice and endoscopic retrograde cholangiopancreatogram (ERCP) established a preoperative diagnosis of Mirizzi syndrome. The other patient's diagnosis of Mirizzi syndrome was made intraoperatively. It is important to properly identify the anatomy at the time of surgery to avoid compromising the common bile duct. Operative treatment of Mirizzi syndrome type II includes laparoscopic or open …

Auditory Filters Measured At Neighboring Center Frequencies, Marc A. Fagelson, C. A. Champlin

ETSU Faculty Works

Auditory filters were derived in 20 normal-hearing human listeners at center frequencies (CFs) of 913, 1095, 3651, and 4382 Hz using the roex (p,r) method. Comparisons were made between slopes of the filters' skirts at the neighboring CFs with filter output levels of 45 and 70 dB. The same comparisons were made with regard to filter equivalent rectangular bandwidth (ERB). In the 1000-Hz region, the low-frequency slopes (Pl) of filters centered at 913 and 1095 Hz were significantly correlated at both stimulus levels, while the high-frequency slopes (Pu) were similar only at the high test level. In the 4000-Hz region, …

Chronicity In Strongyloides Stercoralis Infections: Dichotomy Of The Protective Immune Response To Infective And Autoinfective Larvae In A Mouse Model., R. A. Brigandi, H. L. Rotman, T. J. Nolan, G. A. Schad, D. Abraham

Department of Microbiology and Immunology Faculty Papers

Strongyloidiasis is an intestinal disease that can last for decades due to the occurrence of autoinfective larvae (L3a) in an infected person, which contribute to the maintenance of the population of adult worms in the intestine. The goal of the present study was to determine if L3a are susceptible to the protective immunity that targets the infective stage of the worm, the third-stage larvae (L3). Mice immunized and challenged with Strongyloides stercoralis L3 kill more than 90% of challenge larvae contained within diffusion chambers. The L3 do not remain antigenically static in mice, however, but undergo some degree of antigenic …

RESULTS: Four hundred twenty-six head and body CT scans were performed at the time of presentation of stage III disease. Twenty patients had a true-positive CT scan …

Cloning Of The Mammalian Type Ii Iodothyronine Deiodinase. A Selenoprotein Differentially Expressed And Regulated In Human And Rat Brain And Other Tissues., Walburga Croteau, Jennifer C. Davey, Valerie Anne Galton, Donald L. St Germain

Dartmouth Scholarship

The deiodination of thyroid hormones in extrathyroidal tissues plays an important role in modulating thyroid hormone action. The type II deiodinase (DII) converts thyroxine to the active hormone 3,5,3'-triiodothyronine, and in the rat is expressed in the brain, pituitary gland, and brown adipose tissue (BAT). Complementary DNAs (cDNAs) for the types I and III deiodinases (DI and DIII, respectively) have been isolated and shown to code for selenoproteins. However, information concerning the structure of the mammalian DII remains limited, and the pattern of its expression in human tissues is undefined. We report herein the identification and characterization of rat and …

Measuring Hospital Use Without Claims: A Comparison Of Patient And Provider Reports., R E. Clark, S K. Ricketts, G J. Mchugo

Dartmouth Scholarship

We compared the validity of hospital admission and length of stay reports from patients, outpatient providers, and hospitals, and we examined possible sources of error. Data were collected from people enrolled in a randomized trial of treatment for severe mental illness and substance use disorders, from community mental health centers (CMHCs), and from hospitals. Reports for each of the 74 study participants covered two-year time periods beginning and ending at various times between 1989 and 1993. We compared reports from the various sources and constructed a hybrid with data from all three sources. Using parametric and non-parametric statistics, we compared …

A Polymorphism Of A Platelet Glycoprotein Receptor As An Inherited Risk Factor For Coronary Thrombosis., Ethan J. Weiss, Paul F. Bray, Matthew Tayback, Steven P. Schulman, Thomas S. Kickler, Lewis C. Becker, James L. Weiss, Gary Gerstenblith, Pascal J. Goldschmidt-Clermont

Cardeza Foundation for Hematologic Research

BACKGROUND: Platelet glycoprotein IIb/IIIa is a membrane receptor for fibrinogen and von Willebrand factor, and it has an important role in platelet aggregation. It is known to be involved in the pathogenesis of acute coronary syndromes. Previously, we found a high frequency of a particular polymorphism, PlA2, of the gene encoding glycoprotein IIIa in kindreds with a high prevalence of premature myocardial infarction.

METHODS: To investigate the relation between the PlA2 polymorphism and acute coronary syndromes, we conducted a case-control study of 71 case patients with myocardial infarction or unstable angina and 68 inpatient controls without known heart disease. The …

Analysis Of The Effects Of Overexpression Of Metallothionein-I In Transgenic Mice On The Reproductive Toxicology Of Cadmium., T Dalton, Kai Fu, G C Enders, R D Palmiter, G K Andrews

Journal Articles: Pathology and Microbiology

Exposure to low levels of cadmium reduces fertility. In male mice spermatogenesis is highly sensitive to cadmium, whereas in females the peri-implantation period of pregnancy is sensitive. To examine the potential roles of the cadmium-binding protein, metallothionein (MT), in the reproductive toxicology of cadmium, we examined a transgenic mouse strain that overexpresses metallothionein-I (MT-I). These mice had dramatically increased steady-state levels of MT-I mRNA and MT in the testes and in the female reproductive tract during the peri-implantation period of pregnancy, and this overexpression occurred in a cell-specific and temporally regulated manner similar to that of the endogenous MT-I gene. …

Boys' Participation In Junior Secondary School Physical Education And Sport, Lynn Embrey, M. Drummond

Research outputs pre 2011

According to social lore, boys are meant to be good at Physical Education and sport. There is, however, increasing evidence to the contrary and it is now essential to consider why boys drop out of Physical Education and sport. There has been a good deal of research and subsequent literature detailing the plight of girls' involvement in Physical Education and sport. However, a dearth of literature and research exists where boys Physical Education and sport are concerned. Out of research comes practical implementation strategies that can be adopted by teachers to create a more favourable learning environment. Extensive research on …

Seventy-two male and sixty-nine female varsity players completed a soccer history questionnaire and fourteen physical and skill characteristics were measured. The results indicate that high school soccer players are in slightly better physical condition compared with typical adolescents. Male players are similar to international soccer players of the same age and female players are similar to older international players. There is no difference between gender and position played with …

Ventricular Remodeling Following Infant-Pediatric Cardiac Transplantation. Does Age At Transplantation Or Size Disparity Matter?, Girish S. Shirali, F Lombano, W L. Beeson, D A. Dyar, N F. Mulla, A Khan, J K. Johnston, R E. Chinnock, S R. Gundry, A J. Razzouk

Manuscripts, Articles, Book Chapters and Other Papers

Early left ventricular (LV) remodeling following pediatric cardiac transplantation has not been described. To identify patterns and determinants of change in left ventricular mass and volume posttransplant, we studied 125 consecutive children who underwent cardiac transplantation between January 1, 1989 and July 31, 1993. Two-dimensional imaging-directed M-mode echocardiograms were studied weekly until 26 weeks post-transplant. LV mass and volume (indexed to BSA1.5) were measured. LV mass index increased until 3 weeks post-transplant, and then decreased. The mean decrement in LV mass index after 8 weeks post-transplant (relative to baseline) was significantly larger in patients with donor-recipient weight ratio > 1.5 compared …

The Costs Of Eating: A Behavioral Economic Analysis Of Food Refusal., Mary Louise Kerwin, W H Ahearn, P S Eicher, D M Burd

College of Science & Mathematics Departmental Research

Behavioral economic concepts were applied to the analysis and treatment of pediatric feeding disorders in a clinical setting. In Experiment 1, children who chronically refused food were presented with varying amounts of food on a spoon (empty, dipped, quarter, half, and level). Each child exhibited a different but orderly demand function of response (acceptance, expulsion, and mouth clean) by cost (increasing spoon volume) for a constant pay-off of toys and social interaction. In Experiment 2, physical guidance or nonremoval of the spoon for food refusal was initiated at the smallest spoon volume with low levels of acceptance, and was subsequently …

Mentorship Experiences In A Group Of Occupational Therapy Leaders., Ruth Levine Schemm, Theodore Bross

Department of Occupational Therapy Faculty Papers

OBJECTIVES: The development of occupational therapy leaders is a long-held goal of many members of the American Occupational Therapy Association and of state associations. The initiation of mentor programs is a common means to accomplish this goal. These programs take time and effort, and, although occupational therapists have described how mentorship programs work in the literature, there are few articles that describe the actual mentorship experiences of occupational therapy leaders.

METHOD: To study the experiences of elected occupational therapy leaders, a 30-item questionnaire was distributed at the annual meeting of the Committee of State Association Presidents and completed by 53 …

Roc Curve Regression Analysis: The Use Of Ordinal Regression Models For Diagnostic Test Assessment, Anna N.A. Tosteson, Milton C. Weinstein, Jack Wittenberg, Colin B. Begg

Dartmouth Scholarship

Diagnostic tests commonly are characterized by their true positive (sensitivity) and true negative (specificity) classification rates, which rely on a single decision threshold to classify a test result as positive. A more complete description of test accuracy is given by the receiver operating characteristic (ROC) curve, a graph of the false positive and true positive rates obtained as the decision threshold is varied. A generalized regression methodology, which uses a class of ordinal regression models to estimate smoothed ROC curves has been described. Data from a multi-institutional study comparing the accuracy of magnetic resonance (MR) imaging with computed tomography (CT) …

Elevated Expression Of Type Vii Collagen In The Skin Of Patients With Systemic Sclerosis. Regulation By Transforming Growth Factor-Beta., Lidia Rudnicka, John Varga, Angela M. Christiano, Renato V. Iozzo, Sergio A. Jimenez, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

A hallmark of systemic sclerosis (SSc) is the development of tissue fibrosis. Excessive production of several connective tissue components normally present in the dermis, including type I, III, V, and VI collagens as well as fibronectin and proteoglycans, is a consistent finding in the skin of SSc patients. Type VII collagen is a major constituent of anchoring fibrils, present in the skin at the dermal-epidermal basement membrane zone. TGF-beta has been shown to upregulate the expression of the type VII collagen gene. In this study, we assessed the expression of type VII collagen and TGF-beta in the skin of patients …

Management Decisions Made By Caregiver Spouses Of Persons With Alzheimer's Disease., Mary A. Corcoran

Department of Occupational Therapy Faculty Papers

OBJECTIVES: As the incidence of Alzheimer's disease increases, so does the effect on families and friends who assume caregiving responsibilities. Despite the proliferation of caregiving studies reported in the literature, little is known of the day-to-day management styles and preferences of caregivers. To develop, implement, and test interventions designed to sustain caregivers in their role, more information is needed about the caregiving experience. Results of a descriptive study are presented as a first step in understanding the complex process of choosing, organizing, and implementing everyday caregiving tasks.

METHOD: Subjects of the study were 26 persons who provide care for a …

E-Cadherin Mediates Adherens Junction Organization Through Protein Kinase C, Jani E. Lewis, Pamela J. Jensen, Keith R. Johnson, Margaret J. Wheelock

Biology

Cultured human keratinocytes maintained in 30 μM Ca2+ do not form adherens junctions; however, when the extracellular Ca2+ concentration is raised to 1 mM, adherens junctions form very rapidly. The formation of a junction involves the coordinate organization of intracellular and extracellular components. Cadherins have been shown to mediate this coordinate organization. In this report we show that E-cadherin organizes the various junctional components by signalling through protein kinase C.
