Individualized Learning Plans: Faculty As Facilitators, Ann Burke May 2009

Individualized Learning Plans: Faculty As Facilitators, Ann Burke

Pediatrics Faculty Publications

Introduction: Individualized learning plans (ILPs) are documented personal learning objectives developed by a learner with the help of a facilitator. The Pediatric Residency Review Committee requires residents to accomplish one ILP per year. Faculty members, including program directors, who are newly responsible for facilitating development of resident ILPs may feel unprepared for the task. They are likely unfamiliar with the concepts of ILPs, and most have not created an ILP of their own. Methods: This paper-based faculty development curriculum is designed to educate faculty members on ILPs. The materials include a didactic introduction regarding ILPs and an overview of adult …

Decorin Is A Novel Antagonistic Ligand Of The Met Receptor., Silvia Goldoni, Ashley Humphries, Alexander Nyström, Sampurna Sattar, Rick T Owens, David J Mcquillan, Keith Ireton, Renato V Iozzo May 2009

Decorin Is A Novel Antagonistic Ligand Of The Met Receptor., Silvia Goldoni, Ashley Humphries, Alexander Nyström, Sampurna Sattar, Rick T Owens, David J Mcquillan, Keith Ireton, Renato V Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Decorin, a member of the small leucine-rich proteoglycan gene family, impedes tumor cell growth by down-regulating the epidermal growth factor receptor. Decorin has a complex binding repertoire, thus, we predicted that decorin would modulate the bioactivity of other tyrosine kinase receptors. We discovered that decorin binds directly and with high affinity (K(d) = approximately 1.5 nM) to Met, the receptor for hepatocyte growth factor (HGF). Binding of decorin to Met is efficiently displaced by HGF and less efficiently by internalin B, a bacterial Met ligand. Interaction of decorin with Met induces transient receptor activation, recruitment of the E3 ubiquitin ligase …

Direct To Consumer Drug Advertisements: A Dangerous Game Of Pitching Products To Parents, Lynne Graziano May 2009

Direct To Consumer Drug Advertisements: A Dangerous Game Of Pitching Products To Parents, Lynne Graziano

Annual Conference Presentations, Papers, and Posters

The annual budget for drug advertising in the United States exceeds that for all undergraduate and postgraduate medical education and comes close to the entire budget of the National Institutes of Health. In 2008 drug advertisers spent $4.7 billion, down from a record $4.8 billion in 2006, but up from $2.6 billion in 2002. Since the relaxation of full disclosure rules for television advertising, the amount spent on direct-to-consumer advertisements (DTCA) has soared, leading to increased sales of certain pharmaceuticals, as advertisements are placed in magazines, newspapers, internet websites and on television. These prescription-drug ads prompt nearly one-third of Americans …

Faculty Perceptions Of Interactions Between Students And Registered Nurses In The Clinical Learning Envirorunent, Laurie M. Rosa May 2009

Faculty Perceptions Of Interactions Between Students And Registered Nurses In The Clinical Learning Envirorunent, Laurie M. Rosa

Master's Projects

Perceptions of the relationships between nurses and staff were evaluated from a faculty perspective to uncover the ways that the faculty react, respond, and help to support students. During interviews with faculty, access to practice and clinical unit atmosphere emerged as themes. Faculty described nurses granting access to practice by mentoring students and involving them in the entire care of the patient, or nurses who limited students' access to practice through unprofessional behavior, or "cutting corners." Unit atmosphere influenced learning both positively and negatively depending on inclusion of students, morale, and welcoming behaviors of staff. Faculty acted as guides and …


Covariate-Adjusted Nonparametric Analysis Of Magnetic Resonance Images Using Markov Chain Monte Carlo, Haley Hedlin, Brian S. Caffo, Ziyad Mahfoud, Susan Spear Bassett May 2009

Covariate-Adjusted Nonparametric Analysis Of Magnetic Resonance Images Using Markov Chain Monte Carlo, Haley Hedlin, Brian S. Caffo, Ziyad Mahfoud, Susan Spear Bassett

Johns Hopkins University, Dept. of Biostatistics Working Papers

Permutation tests are useful for drawing inferences from imaging data because of their flexibility and ability to capture features of the brain that are difficult to capture parametrically. However, most implementations of permutation tests ignore important confounding covariates. To employ covariate control in a nonparametric setting we have developed a Markov chain Monte Carlo (MCMC) algorithm for conditional permutation testing using propensity scores. We present the first use of this methodology for imaging data. Our MCMC algorithm is an extension of algorithms developed to approximate exact conditional probabilities in contingency tables, logit, and log-linear models. An application of our non-parametric …


A Gene Expression Predictor Of Response To Egfr-Targeted Therapy Stratifies Progression-Free Survival To Cetuximab In Kras Wild-Type Metastatic Colorectal Cancer, Justin M. Balko, Esther P. Black May 2009

A Gene Expression Predictor Of Response To Egfr-Targeted Therapy Stratifies Progression-Free Survival To Cetuximab In Kras Wild-Type Metastatic Colorectal Cancer, Justin M. Balko, Esther P. Black

Pharmaceutical Sciences Faculty Publications

BACKGROUND: The anti-EGFR monoclonal antibody cetuximab is used in metastatic colorectal cancer (CRC), and predicting responsive patients garners great interest, due to the high cost of therapy. Mutations in the KRAS gene occur in ~40% of CRC and are a negative predictor of response to cetuximab. However, many KRAS-wildtype patients do not benefit from cetuximab. We previously published a gene expression predictor of sensitivity to erlotinib, an EGFR inhibitor. The purpose of this study was to determine if this predictor could identify KRAS-wildtype CRC patients who will benefit from cetuximab therapy.

METHODS: Microarray data from 80 metastatic CRC patients subsequently …

Pivotal Role Of The A2a-Adrenoceptor In Producing Inflammation And Organ Injury In A Rat Model Of Sepsis, Michael Miksa, Padmalaya Des, Mian Zhou, Rongqian Wu, Weifeng Dong, Youxin Ji, Sanna M. Goyert, Thanjavur S. Ravikumar, Ping Wang May 2009

Pivotal Role Of The A2a-Adrenoceptor In Producing Inflammation And Organ Injury In A Rat Model Of Sepsis, Michael Miksa, Padmalaya Des, Mian Zhou, Rongqian Wu, Weifeng Dong, Youxin Ji, Sanna M. Goyert, Thanjavur S. Ravikumar, Ping Wang

Publications and Research

Background: Norepinephrine (NE) modulates the responsiveness of macrophages to proinflammatory stimuli through the activation of adrenergic receptors (ARs). Being part of the stress response, early increases of NE in sepsis sustain adverse systemic inflammatory responses. The intestine is an important source of NE release in the early stage of cecal ligation and puncture (CLP)-induced sepsis in rats, which then stimulates TNF-a production in Kupffer cells (KCs) through the activation of the a2-AR. It is important to know which of the three a2-AR subtypes (i.e., a2A, a2B or a2C) is responsible for the upregulation of TNF-a production. The aim of this …

Can We Apply The Mendelian Randomization Methodology Without Considering Epigenetic Effects?, Ikechkwu U. Ogbuanu, Hongmei Zhang, Wilfried J. Karmaus

Faculty Publications

Introduction: Instrumental variable (IV) methods have been used in econometrics for several decades now, but have only recently been introduced into the epidemiologic research frameworks. Similarly, Mendelian randomization studies, which use the IV methodology for analysis and inference in epidemiology, were introduced into the epidemiologist's toolbox only in the last decade.

Analysis: Mendelian randomization studies using instrumental variables (IVs) have the potential to avoid some of the limitations of observational epidemiology (confounding, reverse causality, regression dilution bias) for making causal inferences. Certain limitations of randomized controlled trials, such as problems with generalizability, feasibility and ethics for some exposures, and high …

Is Volunteering During Adolescence Associated With A Delay In Pregnancy Until Adulthood?, Diane Bishop

Theses and Dissertations

Purpose: The objective of this study was to determine if regular volunteering during adolescence was associated with a delay in first pregnancy until adulthood. Method: Data for this analysis were drawn from Wave III of the National Longitudinal Study of Adolescent Health (Add Health). Logistic regression was used, controlling for demographic characteristics and pregnancy intention, to estimate the independent contribution of volunteering during adolescence to a delay in first pregnancy until after age 18. Results: One-third of respondents reported regularly volunteering during adolescence. Volunteering significantly differed among those who had a teen pregnancy compared to those who delayed pregnancy until …


Effects Of Estrogen On Muscle Damage In Response To An Acute Resistance Exercise Protocol, Megan R. Wolf May 2009

Effects Of Estrogen On Muscle Damage In Response To An Acute Resistance Exercise Protocol, Megan R. Wolf

Honors Scholar Theses

Creatine Kinase (CK) is used as a measure of exercise-induced muscle membrane damage. During acute eccentric (muscle lengthening) exercise, muscle sarcolemma, sarcoplasmic reticulum, and Z-lines are damaged, thus causing muscle proteins and enzymes to leak into the interstitial fluid.

Strenuous eccentric exercise produces an elevation of oxygen free radicals, which further increases muscle damage. Muscle soreness and fatigue can be attributed to this membrane damage. Estradiol, however, may preserve membrane stability post-exercise (Brancaccio, Maffulli, & Limongelli, 2007; Carter, Dobridge, & Hackney, 2001; Tiidus, 2001). Because estradiol has a similar structure to Vitamin E, which is known to have antioxidant properties, …

Psychiatrists' And Psychiatric Aprns' Views Of The Adolescent Mental Health Nurse's Role In The Inpatient Setting, Dana Lehner

Honors Scholar Theses

Current perceptions about nurses’ roles and responsibilities are examined in this study, specifically relating to adolescent inpatient MHNs. Psychiatrists and psychiatric advanced practice registered nurses (APRNs), who work with MHNs and have also published scholarly psychiatric articles, were contacted to request their participation in an anonymous survey hosted by SurveyMonkey.com. This research was conducted to examine the stereotypes that exist against nurses within the health care profession itself, as compared to the pre-existing stereotypes displayed by the media’s view of nurses. Due to investigator time constraints, only six subjects participated in the study. Analysis of survey responses revealed four overarching …


Joint Attention In Young Children With Autism, Sabrina Jara May 2009

Joint Attention In Young Children With Autism, Sabrina Jara

Honors Scholar Theses

Autism spectrum disorders (ASDs) are classified as pervasive developmental disorders characterized by social, communicative, and behavioral impairments. According to formal and informal reports, children with ASD present with receptive and expressive language delay. Joint attention (JA: the behavior that occurs when two individuals focus on the same object or event) has been identified as a possible marker of delayed language development in children with ASD. In this study, the JA behaviors in children with ASD were contrasted with initially language-matched typically developing (TYP) children across three visits.

Measures of language, the frequency, duration, and source of initiation of JA episodes, …

History Of Maltreatment And Psychiatric Impairment In Children In Outpatient Psychiatric Treatment, Kerry Gagnon May 2009

History Of Maltreatment And Psychiatric Impairment In Children In Outpatient Psychiatric Treatment, Kerry Gagnon

Honors Scholar Theses

There is increasing evidence that childhood victimization and attachment disruptions impact a child’s development. In this study, children and adolescents from an outpatient psychiatric clinic were assessed, measuring history of trauma, history of out-of-home placement, initial diagnoses, and CBCL internalizing and externalizing problem scores. Multiple regression analyses showed that both violent abuse trauma (physical/sexual abuse) and victim trauma (physical abuse/sexual abuse/witnessing domestic violence/witnessing community violence) are prevalent among patients with externalizing severity problems; concluding that diagnosis alone may not account for a history of victimization, but externalizing problem severity does. Overall, the study is consistent with past literature that it …


Diagnosing The Prodromal State Of Alzheimer's Disease, Jennifer Bartkowiak May 2009

Diagnosing The Prodromal State Of Alzheimer's Disease, Jennifer Bartkowiak

Honors Scholar Theses

Mild Cognitive Impairment- Amnestic Subtype (MCIa) is a putative prodromal stage of Alzheimer’s Disease (AD) characterized by focal deficits in episodic verbal memory. Less is known about relative deficits in visuospatial learning, although there is ample evidence indicating involvement of the hippocampus in visuospatial learning, as well as hippocampal degeneration in early AD. The aim of this study was to better characterize the components of working memory dysfunction in people with MCIa to increase the ability to reliably diagnose this disease. Fifty-six elderly adults diagnosed with MCIa and 94 healthy elderly completed a hidden maze learning task. Results indicated similar …

The Role Of Epha4 In Glial Scar Formation Following Injury, Krysti Todd May 2009

The Role Of Epha4 In Glial Scar Formation Following Injury, Krysti Todd

Honors Scholar Theses

Although many areas of the brain lose their regenerative capacity with age, stem cell niches have been identified in both the subventricular zone (SVZ) along the lateral walls of the lateral ventricles and the subgranular zone (SGZ) of the dentate gyrus (Gage, 2000; Alvarez-Buylla et al., 2001; Alvarez-Buylla and Lim, 2004). The SVZ niche utilizes many mechanisms to determine the migration patterns of neuroblasts along the RMS into the olfactory bulb, one being Eph/ephrin signaling (Conover et al., 2000; Holmberg et al., 2005). EphA4-mediated signaling is necessary for axon guidance during development, and its continued expression in the SVZ niche …
