Confirmatory Factor Analysis And Invariance Testing Between Blacks And Whites Of The Multidimensional Health Locus Of Control Scale., Marianna Lanoue, Abby Harvey, Dawn B. Mautner, Bon Ku, Kevin Scott

Department of Family & Community Medicine Faculty Papers

The factor structure of the Multidimensional Health Locus of Control scale remains in question. Additionally, research on health belief differences between Black and White respondents suggests that the Multidimensional Health Locus of Control scale may not be invariant. We reviewed the literature regarding the latent variable structure of the Multidimensional Health Locus of Control scale, used confirmatory factor analysis to confirm the three-factor structure of the Multidimensional Health Locus of Control, and analyzed between-group differences in the Multidimensional Health Locus of Control structure and means across Black and White respondents. Our results indicate differences in means and structure, indicating more …

Critical Time Intervention For People Leaving Shelters In The Netherlands: Assessing Fidelity And Exploring Facilitators And Barriers, Renee De Vet, Danielle A. M. Lako, Marielle D. Beijersbergen, Linda Van Den Dries, Sarah Conover, Albert M. Van Hemert, Daniel Herman, Judith R. L. M. Wolf

Publications and Research

International dissemination of evidence-based interventions calls for rigorous evaluation. As part of an evaluation of critical time intervention (CTI) for homeless people and abused women leaving Dutch shelters, this study assessed fidelity in two service delivery systems and explored factors influencing model adherence. Data collection entailed chart review (n = 70) and two focus groups with CTI workers (n = 11). The intervention obtained an overall score of three out of five (fairly implemented) for compliance fidelity and chart quality combined. Fidelity did not differ significantly between service systems, supporting its suitability for a range of populations. The eight themes …

Emerging Immunopharmacological Targets In Multiple Sclerosis., Mojtaba Farjam, Guang-Xian Zhang, Bogoljub Ciric, Abdolmohamad Rostami

Department of Neurology Faculty Papers

Inflammatory demyelination of the central nervous system (CNS) is the hallmark of multiple sclerosis (MS), a chronic debilitating disease that affects more than 2.5 million individuals worldwide. It has been widely accepted, although not proven, that the major pathogenic mechanism of MS involves myelin-reactive T cell activation in the periphery and migration into the CNS, which subsequently triggers an inflammatory cascade that leads to demyelination and axonal damage. Virtually all MS medications now in use target the immune system and prevent tissue damage by modulating neuroinflammatory processes. Although current therapies such as commonly prescribed disease-modifying medications decrease the relapse rate …

Microrna Molecular Profiling From Matched Tumor And Bio-Fluids In Bladder Cancer, David A. Armstrong, Benjamin B. Green, John D. Seigne, Alan R. Schned, Carmen Marsit

Dartmouth Scholarship

MicroRNAs have been identified as potential cancer biomarkers due to their presence and stability in many body fluids including urine and plasma, but the relationship of the pattern of expression of these messengers across various biological media has not been addressed and could provide important information in order to translate these biomarkers for epidemiologic or clinical use. We analyzed microRNA of matched FFPE-tumor tissue, plasma, urine exosomes (n = 16) and WBCs (n = 11) from patients with bladder cancer, using Nanostring miRNA assays and droplet digital PCR for validation. Pearson correlations were used to compare expression between …

Early Shifts Of Brain Metabolism By Caloric Restriction Preserve White Matter Integrity And Long-Term Memory In Aging Mice, Janet Guo, Vikas Bakshi, Ai-Ling Lin

Sanders-Brown Center on Aging Faculty Publications

Preservation of brain integrity with age is highly associated with lifespan determination. Caloric restriction (CR) has been shown to increase longevity and healthspan in various species; however, its effects on preserving living brain functions in aging remain largely unexplored. In the study, we used multimodal, non-invasive neuroimaging (PET/MRI/MRS) to determine in vivo brain glucose metabolism, energy metabolites, and white matter structural integrity in young and old mice fed with either control or 40% CR diet. In addition, we determined the animals’ memory and learning ability with behavioral assessments. Blood glucose, blood ketone bodies, and body weight were also measured. We …

Mice Deficient In Endothelial Α5 Integrin Are Profoundly Resistant To Experimental Ischemic Stroke, Jill Roberts, Leon De Hoog, Gregory J. Bix

Sanders-Brown Center on Aging Faculty Publications

Stroke is a disease in dire need of better therapies. We have previously shown that a fragment of the extracellular matrix proteoglycan, perlecan, has beneficial effects following cerebral ischemia via the α5β1 integrin receptor. We now report that endothelial cell selective α5 integrin deficient mice (α5 KO) are profoundly resistant to ischemic infarct after transient middle cerebral artery occlusion. Specifically, α5 KOs had little to no infarct 2–3 days post-stroke, whereas controls had an increase in mean infarct volume over the same time period as expected. Functional outcome is also improved in the α5 KOs compared with controls. Importantly, no …

Randomized Clinical Trial Comparing Perioperative Care For Breast Cancer Patients At A Patient Hotel Versus A General Surgical Ward, Madleen Anna Camilla Huzell, Johan Frisack, Kristina Dalberg

Patient Experience Journal

Breast cancer is the most frequent cancer among women in Europe and the US. The aim of this study was to assess whether perioperative care, for breast cancer patients, provided at a patient hotel could be an alternative to the conventional care in an ordinary surgical ward. The study focuses solely on the patients’ experience of the provided care with a primary outcome that perioperative care at the patient hotel would be valued better than care in a general ward. Prospective, randomized single centre study. Between 2010 and 2012 a total of 151 patients < 80 years and without severe comorbidities were included in the trial, whereof 76 patients were randomised to the ward group and 75 patients to the hotel group. Five patients were excluded from each group. The validated IN2005-E questionnaire was used to evaluate the patients’ experiences of the care. The response rate was high with 65 patients answering the IN2005-E in each group. No difference could be found between the two groups regarding patient characteristics, type of surgery or tumour characteristics. The patients generally perceived the quality of the provided care as high. However, in the hotel group there was a better experience of care regarding issues such as coordination, privacy, some aspects of medical information, availability and the courtesy of the nurses. For selected patients, perioperative care at a patient hotel is an appreciated alternative to care at a surgical ward.

Improving Process And Enhancing Parent And Therapist Satisfaction Through A Coordinated Intake Approach, Sharla Piecowye, Devona Gibson, Janis Carscadden, Kayla Ueland, Gregory Wells, Scott Oddie

Patient Experience Journal

Recent research indicates that, in Canada, approximately one in five children entering school are not meeting age appropriate milestones in physical, social, language, or cognitive development. Even where support services are available families often face barriers in accessing these. With the goals of improving access to programs, reducing barriers and increasing consistency and efficiency, a new Coordinated Intake Approach (CIA) was developed for families accessing Children’s Rehabilitation Services. It was expected that the CIA would result in 1) parents finding the intake process more satisfactory and easier to complete, 2) therapists feeling more supported and satisfied and 3) a decrease …

The Patient Patient: The Importance Of Knowing Your Navigator, Sarah M. Wheeler Phd, Julie E. Gilbert Phd, Melissa Kaan Mba, Eric Klonikowski, Claire Mb Holloway Md Phd Frcsc

Patient Experience Journal

In Ontario, Diagnostic Assessment Programs (DAPs) have been implemented to improve the quality of care patients receive during the diagnostic phase of the cancer journey. Patient navigators play a critical role in this model by coordinating care and providing information and support to patients and their families. The objectives of this study were 1) to determine whether patient navigation in DAPs is associated with a better patient experience and 2) to examine whether patient navigation in DAPs modifies the effect of wait times and patient volumes on patient experience. Data reflecting patients’ experience within the DAP were collected via survey …

Low-Dose Vitamin K Can Improve Warfarin Control In Patients On Lvad Support, Daizo Tanaka, Venessa L. Kotch, Cheryl Abbas, Gordon Reeves, John Wc Entwistle Iii

The VAD Journal

Background

Anticoagulation with oral vitamin K antagonists (VKA) is very important in patients supported on a left ventricular assist device (LVAD) to prevent thromboembolic complications. Some patients tolerate VKAs poorly and have an unstable INR as a result. It is reported that low-dose vitamin K can improve INR control in patients with an unstable INR in other clinical settings. We evaluated its safety and effectiveness in patients on LVAD support.

Methods

The records of all patients supported on an implantable LVAD between January, 2013 and March, 2014 were reviewed retrospectively to identify those who had received low-dose vitamin K while …

Optical Imaging Of Finger For Blood Pressure Monitoring Of The Driver, Mohammad Motasim Bellah, Mohammad Raziul Hasan, Samir M. Iqbal

Electrical and Computer Engineering Faculty Publications

Cardiovascular diseases (CVDs) are number one reason for human mortality around the world (Fig. 1) [1]. Pulse pressure (PP) and pulse rate (PR) are considered as the two most vital physiological markers for CVDs like myocardial infarction, cardiac arrhythmia, and heart failure. Currently, long-term PP and PR analysis is not possible due to the lack of systems that can frequently measure the data over a period of time. Motor vehicle drivers with known CVDs are at higher risk due to traffic air pollution.

This paper presents our work on an inexpensive and readily deployable approach that keeps track of PP …

A Cytosolic Multiprotein Complex Containing P85Α Is Required For Β-Catenin Activation In Colitis And Colitis-Associated Cancer, Tatiana Goretsky, Emily M. Bradford, Hyunji Ryu, Maryam Tahir, Mary Pat Moyer, Tianyan Gao, Linheng Li, Terrence A. Barrett

Internal Medicine Faculty Publications

Wnt/β-catenin signaling is required for crypt structure maintenance. We previously observed nuclear accumulation of Ser-552 phosphorylated β-catenin (pβ-Cat^Ser-552) in intestinal epithelial cells (IEC) during colitis and colitis-associated cancer. Data here delineate a novel multiprotein cytosolic complex (MCC) involved in β-catenin signaling in the intestine. The MCC contains p85α, the class IA subunit of PI3K, along with β-catenin, 14-3-3ζ, Akt, and p110α. MCC levels in IEC increase in colitis and colitis-associated cancer patients. IEC-specific p85α-deficient (p85^ΔIEC) mice develop more severe dextran sodium …

Loss Of Vglut3 Produces Circadian-Dependent Hyperdopaminergia And Ameliorates Motor Dysfunction And L-Dopa-Mediated Dyskinesias In A Model Of Parkinson's Disease., Christopher B. Divito, Kathy Steece-Collier, Daniel T. Case, Sean-Paul G. Williams, Jennifer A. Stancati, Lianteng Zhi, Maria E. Rubio, Caryl E. Sortwell, Timothy J. Collier, David Sulzer, Robert H. Edwards, Hui Zhang, Rebecca P. Seal

Department of Neuroscience Faculty Papers

UNLABELLED: The striatum is essential for many aspects of mammalian behavior, including motivation and movement, and is dysfunctional in motor disorders such as Parkinson's disease. The vesicular glutamate transporter 3 (VGLUT3) is expressed by striatal cholinergic interneurons (CINs) and is thus well positioned to regulate dopamine (DA) signaling and locomotor activity, a canonical measure of basal ganglia output. We now report that VGLUT3 knock-out (KO) mice show circadian-dependent hyperlocomotor activity that is restricted to the waking cycle and is due to an increase in striatal DA synthesis, packaging, and release. Using a conditional VGLUT3 KO mouse, we show that deletion …

Mice Null For The Deubiquitinase Usp18 Spontaneously Develop Leiomyosarcomas, Fadzai Chinyengetere, David J. Sekula, Yun Lu, Andrew J. Giustini, Aarti Sanglikar, Masanori Kawakami, Tian Ma

Dartmouth Scholarship

USP18 (ubiquitin-specific protease 18) removes ubiquitin-like modifier interferon stimulated gene 15 (ISG15) from conjugated proteins. USP18 null mice in a FVB/N background develop tumors as early as 2 months of age. These tumors are leiomyosarcomas and thus represent a new murine model for this disease.

Sh2 Ligand-Like Effects Of Second Cytosolic Domain Of Na/K-Atpase Α1 Subunit On Src Kinase, Moumita Banerjee, Qiming Duan, Zijian Xie

Pharmaceutical Science and Research

Our previous studies have suggested that the α1 Na/K-ATPase interacts with Src to form a receptor complex. In vitro binding assays indicate an interaction between second cytosolic domain (CD2) of Na/K-ATPase α1 subunit and Src SH2 domain. Since SH2 domain targets Src to specific signaling complexes, we expressed CD2 as a cytosolic protein and studied whether it could act as a Src SH2 ligand in LLC-PK1 cells. Co-immunoprecipitation analyses indicated a direct binding of CD2 to Src, consistent with the in vitro binding data. Functionally, CD2 expression increased basal Src activity, suggesting a Src SH2 ligand-like property of CD2. Consistently, …

Nested Partially-Latent, Class Models For Dependent Binary Data, Estimating Disease Etiology, Zhenke Wu, Maria Deloria-Knoll, Scott L. Zeger

Johns Hopkins University, Dept. of Biostatistics Working Papers

The Pneumonia Etiology Research for Child Health (PERCH) study seeks to use modern measurement technology to infer the causes of pneumonia for which gold-standard evidence is unavailable. The paper describes a latent variable model designed to infer from case-control data the etiology distribution for the population of cases, and for an individual case given his or her measurements. We assume each observation is drawn from a mixture model for which each component represents one cause or disease class. The model addresses a major limitation of the traditional latent class approach by taking account of residual dependence among multivariate binary outcome …
