OBJECTIVE: It is critical that pediatric residents learn to effectively screen families for active and addressable social needs (ie, negative social determinants of health). We sought to determine 1) whether a brief intervention teaching residents about IHELP, a social needs screening tool, could improve resident screening, and 2) how accurately IHELP could detect needs in the inpatient setting.

METHODS: During an 18-month period, interns rotating on 1 of 2 otherwise identical inpatient general pediatrics teams were trained in IHELP. Interns on the other team served as the comparison group. Every admission history and physical examination (H&P) was reviewed for IHELP …

PURPOSE: CD33 is variably expressed on acute myeloid leukemia (AML) blasts and is targeted by gemtuzumab ozogamicin (GO). GO has shown benefit in both adult and pediatric AML trials, yet limited data exist about whether GO response correlates with CD33 expression level.

PATIENTS AND METHODS: CD33 expression levels were prospectively quantified by multidimensional flow cytometry in 825 patients enrolled in Children's Oncology Group AAML0531 and correlated with response to GO.

RESULTS: Patients with low CD33 expression (lowest quartile of expression [Q1]) had no benefit with the addition of GO to conventional chemotherapy (relapse risk [RR]: GO 36% v No-GO 34%, …

Alternative Regulation Of Myc In Lung Cancer, Patrick N. Backman

Open Access Theses

Lung cancer is the leading cause of cancer deaths in the United States, accounting for 27% of all cancer induced deaths1. In an attempt to create a effective targeted therapy for the treatment of lung cancer, a strategy used to treat an activated KrasG12D/+;p53 R172H/+ transgenic lung cancer mouse model was to deliver a known tumor suppressive microRNA (miRNA) to stop tumor growth. The tumor suppressive miRNA let-7 was lentivirally delivered in the form of its primary transcript, pri-let-7a-1, and resulted in increased lung size and inflammation compared to lungs exposed to a control lentivirus. It was identified …

Retigabine Holds Kv7 Channels Open And Stabilizes The Resting Potential, Aaron Corbin-Leftwich, Sayeed M. Mossadeq, Junghoon Ha, Iwona Ruchala, Audrey Han Ngoc Le, Carlos A. Villalba-Galea

School of Pharmacy Faculty Articles

The anticonvulsant Retigabine is a KV7 channel agonist used to treat hyperexcitability disorders in humans. Retigabine shifts the voltage dependence for activation of the heteromeric KV7.2/KV7.3 channel to more negative potentials, thus facilitating activation. Although the molecular mechanism underlying Retigabine's action remains unknown, previous studies have identified the pore region of KV7 channels as the drug's target. This suggested that the Retigabine-induced shift in voltage dependence likely derives from the stabilization of the pore domain in an open (conducting) conformation. Testing this idea, we show that the heteromeric KV7.2/KV7.3 channel has at least two open states, which we named O1 …

Analysis Of Tumor Template From Multiple Compartments In A Blood Sample Provides Complementary Access To Peripheral Tumor Biomarkers., William M Strauss, Chris Carter, Jill Simmons, Erich Klem, Nathan Goodman, Behrad Vahidi, Juan Romero, Michael Masterman-Smith, Ruth O'Regan, Keerthi Gogineni, Lee Schwartzberg, Laura Austin, Paul W Dempsey, Massimo Cristofanilli

Kimmel Cancer Center Faculty Papers

Targeted cancer therapeutics are promised to have a major impact on cancer treatment and survival. Successful application of these novel treatments requires a molecular definition of a patient's disease typically achieved through the use of tissue biopsies. Alternatively, allowing longitudinal monitoring, biomarkers derived from blood, isolated either from circulating tumor cell derived DNA (ctcDNA) or circulating cell-free tumor DNA (ccfDNA) may be evaluated. In order to use blood derived templates for mutational profiling in clinical decisions, it is essential to understand the different template qualities and how they compare to biopsy derived template DNA as both blood-based templates are rare …

Caregiver Opinion Of In-Hospital Screening For Unmet Social Needs By Pediatric Residents., Jeffrey D. Colvin, Jessica L. Bettenhausen, Kaston D. Anderson-Carpenter, Vicki Collie-Akers, Paul J. Chung

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: Child health is strongly influenced by social determinants. Little is known about the opinions of primary caregivers regarding the physicians' role in addressing social needs. Our objective was to examine caregivers' opinions about that role and any associations between those opinions, previous exposure to screening for needs by pediatric residents, and socioeconomic status (SES).

METHODS: Cross-sectional survey study of caregivers of hospitalized children. The survey collected information on caregiver opinion regarding their ability to ask physicians for help with social needs, whether physicians know how to help with those needs, and whether physicians should ask about social needs. The …

Adiponectin At Physiologically Relevant Concentrations Enhances The Vasorelaxative Effect Of Acetylcholine Via Cav-1/Adipor-1 Signaling., Yunhui Du, Rui Li, Wayne Bond Lau, Jianli Zhao, Bernard Lopez, Theodore A Christopher, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

Clinical studies have identified hypoadiponectinemia as an independent hypertension risk factor. It is known that adiponectin (APN) can directly cause vasodilation, but the doses required exceed physiologic levels several fold. In the current study, we determine the effect of physiologically relevant APN concentrations upon vascular tone, and investigate the mechanism(s) responsible. Physiologic APN concentrations alone induced no significant vasorelaxation. Interestingly, pretreatment of wild type mouse aortae with physiologic APN levels significantly enhanced acetylcholine (ACh)-induced vasorelaxation (P

A Study On Sanguinarine As An Antileukemic Agent- Involvement Of Reactive Oxygen Species-Ceramide-Akt Apoptotic Signaling Pathway, Anees Rahman Cheratta

Dissertations

Dysregulation of apoptosis is a prime hallmark of leukemia. Therefore, drugs which restore the sensitivity of leukemic cells to apoptotic stimuli are promising candidates in the treatment of leukemia. The main objective of this dissertation was to examine the antileukemic effect of sanguinarine, in vitro, and to further examine the signaling mechanisms that may be involved. This study demonstrates that in human leukemic cells, sanguinarine activates a caspase-dependent apoptotic cell death pathway that is characterized by reactive oxygen species-dependent ceramide generation, and subsequent inhibition of Akt signaling pathway. In addition, sanguinarine also induces reactive oxygen species-dependent glutathione depletion and …

Sinabro: A Smartphone-Integrated Opportunistic Electrocardiogram Monitoring System, Sungjun Kwon, Dongseok Lee, Jeehoon Kim, Youngki Lee, Seungwoo Kang, Sangwon Seo, Kwangsuk Park

Research Collection School Of Computing and Information Systems

In our preliminary study, we proposed a smartphone-integrated, unobtrusive electrocardiogram (ECG) monitoring system, Sinabro, which monitors a user's ECG opportunistically during daily smartphone use without explicit user intervention. The proposed system also monitors ECG-derived features, such as heart rate (HR) and heart rate variability (HRV), to support the pervasive healthcare apps for smartphones based on the user's high-level contexts, such as stress and affective state levels. In this study, we have extended the Sinabro system by: (1) upgrading the sensor device; (2) improving the feature extraction process; and (3) evaluating extensions of the system. We evaluated these extensions with a …

Elderly Medication Adherence Monitoring With The Internet Of Things, Xiaoping Toh, Hwee Xian Tan, Huiguang Liang, Hwee-Pink Tan

Research Collection School Of Computing and Information Systems

With the growth in elderly population in Singapore, healthcare expenditure and prevalence of age-related illnesses are expected to increase. Non-adherence among the elderly is a common issue that leads to adverse health complications, particularly among those with chronic conditions. However, existing studies typically focus on identifying predictors of medication adherence, and provide neither user-friendly nor actionable solutions that can be easily adopted by the elderly.In this paper, we use the Internet of Things to monitor medication adherence and detect changes in medication consumption patterns among the elderly, thus enabling timely interventions by caregivers to take place. Sensor-enabled medication boxes are …

Role Of Heme Oxygenase-1 In The Pathogenesis And Tumorigenicity Of Kaposi's Sarcoma-Associated Herpesvirus, Lu Dai, Jing Qiao, David Nguyen, Amanda P. Struckhoff, Lisa Doyle, Karlie Bonstaff, Luis Del Valle, Chris Parsons, Bryan P. Toole, Rolf Renne, Zhiqiang Qin

School of Medicine Faculty Publications

Kaposi's Sarcoma-associated Herpesvirus (KSHV) is the etiologic agent of several malignancies, including Kaposi's Sarcoma (KS), which preferentially arise in immunocompromised patients such as HIV+ subpopulation and lack effective therapeutic options. Heme oxygenase-1 (HO-1) has been reported as an important regulator of endothelial cell cycle control, proliferation and angiogenesis. HO-1 has also been found to be highly expressed in KSHV-infected endothelial cells and oral AIDS-KS lesions. We previously demonstrate that the multifunctional glycoprotein CD147 is required for KSHV/LANA-induced endothelial cell invasiveness. During the identification of CD147 controlled downstream genes by microarray analysis, we found that the expression of HO-1 is significantly …

Use Of Concomitant Antibiotics During Treatment For Clostridium Difficile Infection (Cdi) In Pediatric Inpatients: An Observational Cohort Study., Vanessa W. Stevens, Cary Thurm, Elyse M. Schwab, Matthew P. Kronman, Jeffrey S. Gerber, Samir S. Shah, Jason G. Newland, Joshua Courter, Sarah Parker, Thomas V. Brogan, Adam L. Hersh

Manuscripts, Articles, Book Chapters and Other Papers

Concomitant antibiotic use during treatment for Clostridium difficile infection (CDI) increases the risk of recurrence. Across a network of children's hospitals, 46% of patients treated for CDI received concomitant antibiotics for a median of 7 days. Concomitant antibiotic use was more common among patients with malignancies, and solid organ or bone marrow transplant. Unnecessary concomitant antibiotic use in CDI patients is a potential target for pediatric antimicrobial stewardship.

Pharmaceutical Contaminants As Stressors On Rocky Intertidal And Estuarine Organisms: A Case Study Of Fluoxetine, Joseph Richard Peters

Dissertations and Theses

Contaminants such as pharmaceuticals are of increasing concern due to their ubiquitous use and persistence in surface waters worldwide. Limited attention has been paid to the effects of pharmaceuticals on marine life, despite widespread detection of these contaminants in the marine environment. Of the existing studies, the majority assess the negative effects of pharmaceuticals over an exposure period of 30 days or less and focus on cellular and subcellular biomarkers. Longer studies are required to determine if chronic contaminant exposure poses risks to marine life at environmentally relevant concentrations. Also scarce in the literature is examination of whole organism effects …

Closed-Loop Cfd Analysis Of The Fontan Cardiovascular Circulation, Marwan Hameed

Doctoral Dissertations and Master's Theses

One out of 150 newborn babies born with congenital heart disease, approximately 7.5% of those infants have a single ventricle (SV). The Fontan operation, which is a procedure to create a harmonious circulation in SV patients, has been performed for a long time to save the newborn patients. In this procedure the superior vena cava and inferior vena cava, which carry the oxygen-poor blood from the upper and lower body back to the heart, are linked directly to the pulmonary arteries, bypassing the atrial connection. Even though this operation has been around for years, the patients who have undergone this …

Structure-Activity Relationships Governing The Interaction Of Nanoparticles With Mammalian Cells- Predictive Models For Toxicology And Medical Appliances, Marcus A. Maher

Doctoral

Nanoscience is seen as one of the key enabling technologies of the 20th century and as its range of applications increases it is important to look at how nanomaterials interact with biological environments. Some of these interactions have given rise to toxic effects and thus, the creation of the field of nanotoxicology, it has also been noted that current methods of evaluating toxicity may not be sufficient to keep up with the rapidly emerging range of nanomaterials becoming available. It is clear that alternatives are necessary. In this thesis, a phenomenological rate equation model is constructed to simulate nanoparticle uptake …

An Investigation Into The Dietary And Health Behaviours Of Pregnant Women In Ireland, Laura Mullaney

Doctoral

Maternal obesity increases the risk of metabolic complications in pregnancy such as gestational diabetes mellitus (GDM). Effective weight management following childbirth may reduce long-term metabolic risks among women of child bearing age. The aim of this study was to investigate the diet and health behaviours of pregnant and postpartum women in Ireland. Accurate dietary assessment in pregnancy is often difficult to achieve. We have shown that dietary under-reporting is more likely among pregnant women who are younger, materially deprived, obese and who have increased adiposity. These findings suggest that dietary underreporting represents a source of potential bias in obstetric obesity …

A Call For The Structured Physicist Report, John M. Boone, Phd, Mahadevappa Mahesh, Ms, Phd, Eric L. Gingold, Phd, J. Anthony Seibert, Phd

Department of Radiology Faculty Papers

Introduction:

The field of diagnostic radiology continues to struggle with the clinical adoption of the structured interpretive report, with many radiologists preferring a semistructured, free-text dictation style to a more rigid, highly structured approach that some professional leaders have promoted [1]. Although structured reporting compliance in the radiologist community has been difficult to achieve, diagnostic radiologists have been thinking about and discussing this important issue for many years; it is also a part of the ACR’s Imaging 3.0_ campaign [2]. In the breast imaging community, the well-established BI-RADS_ recommendations produce a very structured report, with a discussion of interpretive findings …
