Igf-I Induces Upregulation Of Ddr1 Collagen Receptor In Breast Cancer Cells By Suppressing Mir-199a-5p Through The Pi3k/Akt Pathway., Roberta Matà, Chiara Palladino, Maria Luisa Nicolosi, Anna Rita Lo Presti, Roberta Malaguarnera, Marco Ragusa, Daniela Sciortino, Andrea Morrione, Marcello Maggiolini, Veronica Vella, Antonino Belfiore

Kimmel Cancer Center Faculty Papers

Discoidin Domain Receptor 1 (DDR1) is a collagen receptor tyrosine-kinase that contributes to epithelial-to-mesenchymal transition and enhances cancer progression. Our previous data indicate that, in breast cancer cells, DDR1 interacts with IGF-1R and positively modulates IGF-1R expression and biological responses, suggesting that the DDR1-IGF-IR cross-talk may play an important role in cancer.In this study, we set out to evaluate whether IGF-I stimulation may affect DDR1 expression. Indeed, in breast cancer cells (MCF-7 and MDA-MB-231) IGF-I induced significant increase of DDR1 protein expression, in a time and dose dependent manner. However, we did not observe parallel changes in DDR1 mRNA. DDR1 …

Effect Of Diabetes Self-Management Education On Glycemic Control, Compared To Usual Care In Type 2 Diabetic Patients At The Family Medicine Clinic, Aga Khan University Hospital Nairobi, Catherine Wanjiku Gathu

Master of Medicine in Family Medicine

Background: Globally, the magnitude of disease burden associated with diabetes is high. Poor glycemic control contributes greatly to this burden, especially in the occurrence of related complications. The value of Diabetes Self-Management Education (DSME) is evident in literature, and has been recommended as a way of optimizing glycemic and metabolic control and averting early onset of diabetes complications. Usual care involves spontaneous sharing of information during medical consultations without planned structure or defined time frame. In the African setting, the effect of DSME, and how it compares to usual care, is yet to be fully explored. Objective: To compare the …

Leiby, Phd, Barbara Pro, Md, John David Sprandio, Jr. Md, Diana Whitaker-Menezes, Phd, Paolo Cotzia, Md, Guldeep Uppal, Md, Jaime Caro, Md, Jerald Z. Gong, Md, Ubaldo E. Martinez-Outshoorn, Md

Department of Medical Oncology Posters

It has previously been suggested that the tumor microenvironment in diffuse large B-cell lymphoma (DLBCL) has prognostic significance. Furthermore, gene expression profiling in DLBCL patients has identified separate subsets with glycolytic and mitochondrial (oxidative phosphorylative) metabolic signatures.

Glycolytic metabolism forms the basis for FDG PET scans, widely used in staging and response assessment in DLBCL. While many assume that the tumor as a whole is primarily glycolytic, the metabolic patterns of cancer cells (C) and surrounding cancer-associated stromal cells (CAS) remain relatively unknown. We investigated the in situ metabolic patterns of C and CAS cells as well as tumor-associated macrophages …

Chronic Ethanol Exposure Enhances The Aggressiveness Of Breast Cancer: The Role Of P38Γ, Mei Xu, Siying Wang, Zhenhua Ren, Jacqueline A. Frank, Xiuwei H. Yang, Zhuo Zhang, Zun-Ji Ke, Xianglin Shi, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Both epidemiological and experimental studies suggest that ethanol may enhance aggressiveness of breast cancer. We have previously demonstrated that short term exposure to ethanol (12–48 hours) increased migration/invasion in breast cancer cells overexpressing ErbB2, but not in breast cancer cells with low expression of ErbB2, such as MCF7, BT20 and T47D breast cancer cells. In this study, we showed that chronic ethanol exposure transformed breast cancer cells that were not responsive to short term ethanol treatment to a more aggressive phenotype. Chronic ethanol exposure (10 days - 2 months) at 100 (22 mM) or 200 mg/dl (44 mM) caused the …

This study aimed to evaluate the relation between AOD level and clinical outcomes in a cohort of CKD patients in Taiwan.

Methods: 262 CKD patients without dialysis at a hospital in Taiwan were consecutively recruited, from 2010 to 2011, and followed up for 3 years. At enrollment, demographic and clinical data were obtained, including baseline level measurement of AOD, using the …

Handoff Communication In The Emergency Department, Kristen Matichko

DNP Forum

The communication of patient information through use of handoff ensures continuity of care and patient safety. A study of hand-off reports between pre-hospital personnel and staff in the emergency department revealed a lack of complete or formal information dialogue. Nurses play a vital role in the process of communication and information exchange through the use of handoff despite minimal guidelines for that exchange in current nursing practice. The pre-hospital hand-off informational exchange impacts patient safety as well as the planning and implementation of nursing care based upon that information.

The sample used was from a convenience sampling of patients arriving …

18f-Fdg Pet/Ct Imaging Of Extranodal Rosai-Dorfman Disease With Hepatopancreatic Involvement - A Pictorial And Literature Review., Faiq A. Shaikh Md, Omer Awan Md, Mph, Sohaib A. Mohiuddin Md, Saleem Farooqui, Salman A. Khan, William Mccartney

Department of Radiology & Diagnostic Medical Imaging

We share our experience with serial PET/CT imaging on a patient with extranodal Rosai-Dorfman disease (RDD) with hepatopancreatic involvement. RDD is a benign proliferative disorder of histiocytes mainly involving the lymph nodes. It typically presents with fever and painless cervical lymphadenopathy in young adults and less than half of RDS cases demonstrate extranodal involvement. RDD involvement of the liver and pancreas is extremely rare, and this case highlights the role of PET/CT in its management.

Silibinin-Mediated Metabolic Reprogramming Attenuates Pancreatic Cancer-Induced Cachexia And Tumor Growth., Surendra K. Shukla, Aneesha Dasgupta, Kamiya Mehla, Venugopal Gunda, Enza Vernucci, Joshua J. Souchek, Gennifer Goode, Ryan King, Anusha Mishra, Ibha Rai, Sangeetha Nagarajan, Nina V. Chaika, Fang Yu, Surendra K. Shukla

Journal Articles: Eppley Institute

Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer-related deaths in the US. Cancer-associated cachexia is present in up to 80% of PDAC patients and is associated with aggressive disease and poor prognosis. In the present studies we evaluated an anti-cancer natural product silibinin for its effectiveness in targeting pancreatic cancer aggressiveness and the cachectic properties of pancreatic cancer cells and tumors. Our results demonstrate that silibinin inhibits pancreatic cancer cell growth in a dose-dependent manner and reduces glycolytic activity of cancer cells. Our LC-MS/MS based metabolomics data demonstrates that silibinin treatment induces global metabolic reprogramming in pancreatic …

Combined Systemic And Ocular Chemotherapy For Anterior Segment Metastasis Of Systemic Mantle Cell Lymphoma., Aniruddha Agarwal, Mohammad Ali Sadiq, William R. Rhoades, Loren S. Jack, Mostafa Hanout, Philip J. Bierman, William W. West, Quan Dong Nguyen

Journal Articles: Ophthalmology

BACKGROUND: Mantle cell lymphoma (MCL) is an aggressive subtype of non-Hodgkin's lymphoma that rarely metastasizes to the iris and the anterior segment. Blastic/pleomorphic morphology is thought to have an adverse effect on prognosis in MCL. MCL is resistant to conventional chemotherapeutic regimens with a tendency for multiple relapses. Management of anterior segment metastasis of systemic MCL has not been described in literature.

FINDINGS: A 58-year-old male presented with an aggressive, relapsing, metastatic, systemic blastic variant of MCL with ocular involvement. At the time of initial presentation, large tumor cells were visible in the anterior chamber (AC) along with hypopyon and …

Surgery Faculty Publications

PURPOSE: To identify factors associated with an increased risk of fractures in Long-Gap Esophageal Atresia (LGEA) patients. Following implementation of a risk-stratified program, we hypothesized a reduction in fracture incidence within this potentially high-risk population.

METHODS: A retrospective review of LGEA-patients admitted between 2005 and 2014 was conducted. Symptomatic fractures with radiographic confirmation were defined as events. Univariate and multivariable analysis evaluated factors including admission weight-for-age z-score, primary versus secondary Foker process (FP), weight at Foker Stage I, days and episodes of paralysis, number of parenteral nutrition (PN) days, cumulative dose of loop diuretics adjusted for body weight and days …

Effect Of Kidney Function On Drug Kinetics And Dosing In Neonates, Infants, And Children., Frederique Rodieux, Melanie Wilbaux, Johannes N. Van Den Anker, Marc Pfister

Pediatrics Faculty Publications

Neonates, infants, and children differ from adults in many aspects, not just in age, weight, and body composition. Growth, maturation and environmental factors affect drug kinetics, response and dosing in pediatric patients. Almost 80 % of drugs have not been studied in children, and dosing of these drugs is derived from adult doses by adjusting for body weight/size. As developmental and maturational changes are complex processes, such simplified methods may result in subtherapeutic effects or adverse events. Kidney function is impaired during the first 2 years of life as a result of normal growth and development. Reduced kidney function during …

Levels Of Glycosaminoglycans In The Cerebrospinal Fluid Of Healthy Young Adults, Surrogate-Normal Children, And Hunter Syndrome Patients With And Without Cognitive Impairment., Christian J Hendriksz, Joseph Muenzer, Adeline Vanderver, Jonathan M Davis, Barbara K Burton, Nancy J Mendelsohn, Nan Wang, Luying Pan, Arian Pano, Ann J Barbier

Neurology Faculty Publications

In mucopolysaccharidoses (MPS), glycosaminoglycans (GAG) accumulate in tissues. In MPS II, approximately two-thirds of patients are cognitively impaired. We investigated levels of GAG in cerebrospinal fluid (CSF) in different populations from four clinical studies (including NCT00920647 and NCT01449240). Data indicate that MPS II patients with cognitive impairment have elevated levels of CSF GAG, whereas those with the attenuated phenotype typically have levels falling between those of the cognitively affected patients and healthy controls.

Interaction Of Alu Polymorphisms And Novel Measures Of Discrimination In Association With Blood Pressure In African Americans Living In Tallahassee, Alexis C. Boulter, Jackyn Quinlan, Aida T. Miró-Herrans, Laurel N. Pearson, Nubiana L. Todd, Clarence C. Gravlee, Connie J. Mulligan

Human Biology Open Access Pre-Prints

African Americans are 40% more likely to be afflicted with hypertension in comparison to non-Hispanic, white Americans, resulting in a 30% higher instance of mortality due to cardiovascular disease. There is debate about the relative contributions of genetic and sociocultural risk factors to the racial disparity in hypertension.

We assayed three Alu insertion polymorphisms located in the angiotensin-1-converting enzyme (ACE), tissue plasminogen activator (PLAT), and with no-lysine kinase 1 (WNK1) genes. We also estimated West African genetic ancestry and developed novel measures of perceived discrimination to create a biocultural model of blood pressure among …

Outbreak: Emergency Room Overcrowding, Mary Elizabeth Sum

University Honors Program

A phenomenon referred to as emergency room (ER) overcrowding, which is defined as, “the demand for emergency services exceeds the ability of physicians and nurses to provide quality care within a reasonable time” (Sinclair, 2007), is happening around the world today. This problem causes much grief for the patients trying to receive quality care from the affected hospitals, and therefore hospitals are looking for any solution to solve this problem. The research was conducted by a literary review by utilizing the CINAHL and the Nursing and Allied Health Collection database. It was conducted to discover any evidence of ER overcrowding, …

Pediatrics Faculty Publications

The temporal version of the pediatric sepsis biomarker risk model (tPERSEVERE) estimates the risk of a complicated course in children with septic shock based on biomarker changes from days 1 to 3 of septic shock. We validated tPERSEVERE performance in a prospective cohort, with an a priori plan to redesign tPERSEVERE if it did not perform well. Biomarkers were measured in the validation cohort (n = 168) and study subjects were classified according to tPERSEVERE. To redesign tPERSEVERE, the validation cohort and the original derivation cohort (n = 299) were combined and randomly allocated to training (n = 374) and …

An Intra-Bone Axial Load Transducer: Development And Validation In An In-Vitro Radius Model, Nikolas K. Knowles, Michael Gladwell, Louis M. Ferreira

Surgery Publications

Background

Accurate measurement of forces through the proximal radius can assess the effects of some surgical procedures on radioulnar load sharing, but is difficult to achieve given the redundant loading nature of the musculoskeletal system. Previously reported devices have relied on indirect measurements that may alter articular joint location and function. An axial load transducer interposed in the diaphysis of the radius may accurately quantify unknown axial loads of the proximal radius, and maintain articular location.

Methods

An in-vitro radius model was developed by interposing an axial load transducer in the diaphysis of the proximal radius. Static loads of 20, …
