Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: We update the psychometric properties of the Hypoglycemia Fear Survey-Parents of Young Children (HFS-PYC), a 26-item measure of parents' hypoglycemia fear for young children using an insulin pump.

METHODS: We combined three similar datasets for the analyses. The data analyzed included parents' responses to the HFS-PYC and a demographic form. For a subset of children (n = 91), we also analyzed self-monitoring of blood glucose data. We used confirmatory factor analysis (CFA) to confirm the measure's original factor structure. Additional analyses examined reliability and validity of a revised HFS-PYC for parents of young children using pumps.

RESULTS: We analyzed …

Surrogate Pregnancy After Prenatal Diagnosis Of Spina Bifida., Lynnette J. Mazur, Mary Kay Kisthardt, Helen H. Kim, Laura M. Rosas, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

Some pregnancies today involve infertile individuals or couples who contract with a fertile woman to carry a pregnancy for them. The woman who carries the pregnancy is referred to as a "gestational carrier." The use of such arrangements is increasing. Most of the time, these arrangements play out as planned; sometimes, however, problems arise. This article discusses a case in which a fetal diagnosis of spina bifida led the infertile couple to request that the gestational carrier terminate the pregnancy, and the gestational carrier did not wish to do so. Experts in the medical and legal issues surrounding surrogacy discuss …

Multilevel Modeling Of Binary Outcomes With Three-Level Complex Health Survey Data., Shafquat Rozi, Sadia Mahmud, Gillian Lancaster, Wilbur Hadden, Gregory Pappas Feb 2017

Multilevel Modeling Of Binary Outcomes With Three-Level Complex Health Survey Data., Shafquat Rozi, Sadia Mahmud, Gillian Lancaster, Wilbur Hadden, Gregory Pappas

Community Health Sciences

Complex survey designs often involve unequal selection probabilities of clus-ters or units within clusters. When estimating models for complex survey data, scaled weights are incorporated into the likelihood, producing a pseudo likeli-hood. In a 3-level weighted analysis for a binary outcome, we implemented two methods for scaling the sampling weights in the National Health Survey of Pa-kistan (NHSP). For NHSP with health care utilization as a binary outcome we found age, gender, household (HH) goods, urban/rural status, community de-velopment index, province and marital status as significant predictors of health care utilization (p-value < 0.05). The variance of the random intercepts using scaling method 1 is estimated as 0.0961 (standard error 0.0339) for PSU level, and 0.2726 (standard error 0.0995) for household level respectively. Both esti-mates are significantly different from zero (p-value < 0.05) and indicate consid-erable heterogeneity in health care utilization with respect to households and PSUs. The results of the NHSP data analysis showed that all three analyses, weighted (two scaling methods) and un-weighted, converged to almost identical results with few exceptions. This may have occurred because of the large num-ber of 3rd and 2nd level clusters and relatively small ICC. We performed a sim-ulation study to assess the effect of varying prevalence and intra-class correla-tion coefficients (ICCs) on bias of fixed effect parameters and variance components of a multilevel pseudo maximum likelihood (weighted) analysis. The simulation results showed that the performance of the scaled weighted estimators is satisfactory for both scaling methods. Incorporating simulation into the analysis of complex multilevel surveys allows the integrity of the results to be tested and is recommended as good practice.

Diagnosis And Treatment Of Cd20 Negative B Cell Lymphomas, Tasleem Katchi, Delong Liu

NYMC Faculty Publications

CD20 negative B cell non-Hodgkin lymphoma (NHL) is rare and accounts for approximately 1-2% of B cell lymphomas. CD20- negative NHL is frequently associated with extranodal involvement, atypical morphology, aggressive clinical behaviour, resistance to standard chemotherapy and poor prognosis. The most common types of these include plasmablastic lymphoma, primary effusion lymphoma, large B-cell lymphoma arising from HHV8-associated multicentric Castleman's disease, and ALK+ large B cell lymphoma. This review provides an overview of the diagnostic and treatment modalities for CD20 negative B cell NHL.

What Can A Primary Care Physician Discuss With Older Patients To Improve Advance Directive Completion Rates? A Clin-Iq, Judith M. Myers, Edmund Duthie Jr., Kathryn Denson, Steven Denson, Deborah Simpson Jan 2017

What Can A Primary Care Physician Discuss With Older Patients To Improve Advance Directive Completion Rates? A Clin-Iq, Judith M. Myers, Edmund Duthie Jr., Kathryn Denson, Steven Denson, Deborah Simpson

Journal of Patient-Centered Research and Reviews

Advance directives (ADs) provide patients with the opportunity to indicate their preferences for medical care while they still maintain the capacity to express their wishes, thus retaining autonomy. ADs increase the likelihood that patients will receive the care they desire, as their family members and physicians will better understand the level of care desired. Despite this, the AD completion rate by elderly patients continues to be low, especially for patients not facing serious illnesses. Primary care physicians (PCPs) are uniquely positioned to engage patients in discussions about ADs before a health crisis arises yet often do not due to time …

Novel Compound, 84f2, Inhibits Calmodulin Deficient Ryr2, Robert Carl Klipp Jan 2017

Novel Compound, 84f2, Inhibits Calmodulin Deficient Ryr2, Robert Carl Klipp

Dissertations and Theses

The cardiac ryanodine receptor (RyR2) plays a key role in excitation-contraction coupling (ECC). Mutations in RyR2 are known to be linked to the arrhythmogenic disorder, catecholaminergic polymorphic ventricular tachycardia (CPVT), a deadly disease which is characterized by a leak of calcium from sarcoplasmic reticulum and a decrease in calmodulin (CaM) binding. A novel drug, 84F2, shown to inhibit arrhythmias in RyR2-R176Q heterozygous CPVT mouse hearts (2.5 µg/kg), decrease spark frequency in cells derived from CPVT mice (IC50 = 35 nM), and inhibit RyR2 single channel activity at low nanomolar concentrations (IC50 = 8 nM). When CaM is added …

Integrins, a family of heterodimeric receptors for extracellular matrix, are promising therapeutic targets for ovarian cancer, particularly high-grade serous-type (HGSOC), as they drive tumor cell attachment, migration, proliferation and survival by activating focal adhesion kinase (FAK)-dependent signaling. Owing to the potential off-target effects of FAK inhibitors, disruption of the integrin signaling axis remains to be a challenge. Here, we tackled this barrier by screening for inhibitors being functionally cooperative with small-molecule VS-6063, a phase II FAK inhibitor. From this screening, JQ1, a potent inhibitor of Myc oncogenic network, emerged as the most robust collaborator. Treatment with a combination of VS-6063 …

Parent And Child Report Of Pain And Fatigue In Jia: Does Disagreement Between Parent And Child Predict Functional Outcomes?, Amy C. Gaultney, Maggie H. Bromberg, Mark Connelly, Tracy Spears, Laura E. Schanberg

Manuscripts, Articles, Book Chapters and Other Papers

While previous research in juvenile idiopathic arthritis (JIA) has identified discrepancy between parent and child perception of disease-related symptoms such as pain, the significance and impact of this disagreement has not been characterized. We examined the extent to which parent-child discordance in JIA symptom ratings are associated with child functional outcomes. Linear regression and mixed effects models were used to test the effects of discrepancy in pain and fatigue ratings on functional outcomes in 65 dyads, consisting of youth with JIA and one parent. Results suggested that children reported increased activity limitations and negative mood when parent and child pain …

Hyperglycemia (HG) stimulates the production of reactive oxygen species in the heart through activation of NADPH oxidase 2 (NOX2). This production is independent of glucose metabolism but requires sodium/glucose cotransporters (SGLT). Seven SGLT isoforms (SGLT1 to 6 and sodium-myoinositol cotransporter-1, SMIT1) are known, although their expression and function in the heart remain elusive. We investigated these 7 isoforms and found that only SGLT1 and SMIT1 were expressed in mouse, rat and human hearts. In cardiomyocytes, galactose (transported through SGLT1) did not activate NOX2. Accordingly, SGLT1 deficiency did not prevent HG-induced NOX2 activation, ruling it out in the cellular response to …

From Emt To Hsc To Aml: Zeb2 Is A Cell Fate Switch., Sara E. Meyer Jan 2017

From Emt To Hsc To Aml: Zeb2 Is A Cell Fate Switch., Sara E. Meyer

Department of Cancer Biology Faculty Papers

In this issue of Blood, complimentary studies by J. Li et al1 and H. Li et al2 identify the transcription factor ZEB2 as a critical regulator of multilineage differentiation in both normal and malignant hematopoiesis. In particular, these studies show that ZEB2 is an inhibitor of normal granulocyte production, and in acute myeloid leukemia (AML), antagonizing ZEB2 function releases the granulocytic differentiation block, creating an antileukemic therapeutic effect.

Orthopaedic Surgeon Density In West Virginia, Franklin D. Shuler, Grant S. Buchanan, Zachary Sanford, Milad Modarresi, James Timothy Reagan, Kelly Scott, Chad Fisher, Ali Oliashirazi

Marshall Journal of Medicine

Abstract

West Virginia (WV) has many healthcare disparities and access barriers. For bone and joint disorders, WV has some of the highest rates of musculoskeletal problems, including the highest reported rate of adult arthritis in the nation (36.2%). We hypothesized that WV has one of the lowest Orthopaedic surgeon densities in the country, which can negatively impact the delivery of musculoskeletal care. Using the WV Board of Medicine practitioner databank, the Veterans Administration practitioner data, and national Orthopaedic surgeon census data, we demonstrated a considerably low Orthopaedic surgeon density in WV (7.71/100,000 population versus the national average of 8.51/100,000 population) …
