Writing Panels Articulate Extension Public Value In The West, Ja.N B. Carroll, Roxie Rogers Dinstel, Linda Marie Manton Dec 2015

Writing Panels Articulate Extension Public Value In The West, Ja.N B. Carroll, Roxie Rogers Dinstel, Linda Marie Manton

Journal of Extension

In every era, publically funded programs seek to document their value. During the centennial celebrations of Cooperative Extension's legislation and establishment, this cry for data became even louder and the demand more intense. The Western Extension Directors Association (WEDA) tasked their Western Region Program Leadership Committee (WRPLC) to determine common measures in hopes that 15 Western States could aggregate data and effectively present results of Extension's work to stakeholders. Panels of experts from western land-grant universities were convened for an orientation to public value and a 24-hour "lock down" writing session. This tool resulted in six formatted white papers.

Overcrowding In The Emergency Departments: Challenges And Opportunities For Improvement, Muhammad Akbar Baig, Asad Mian, Fatima Najeeb, Hira Shahzad Dec 2015

Overcrowding In The Emergency Departments: Challenges And Opportunities For Improvement, Muhammad Akbar Baig, Asad Mian, Fatima Najeeb, Hira Shahzad

Department of Emergency Medicine

With the advent of Emergency Medicine, one can observe an increase in the number of Emergency Departments (ED) across the country. However, most EDs struggle due to an overwhelming number of patients. Overcrowding can lead to delays in patient care. For a city like Karachi which is an active disaster zone, preemptive preparedness is required in the face of terror threats and such overcrowding needs to be decreased to a bare minimum. The most frequent causes of prolonged length of stay (LOS) in the ED include non-availability of in-hospital beds, delays in response to subspecialty consultations and escalating medical expenses. …

Learning By Design, Design By Learning: An Investigation Into (Re)Designing A Rochester School For The Future Of Learning, Catherine C. Lange

Theses

School buildings and their learning environments have remained relatively static over time. Many of the classrooms still in use today were built for traditional, “chalk-n-talk” pedagogies and passive learning; they are not prepared for today’s more active learning approaches.1 Innovative schools are beginning to adopt new curricula and pedagogical strategies that align with research being done on student learning outcomes. In Rochester, New York, an initiative called the Rochester Schools Modernization Program (RSMP) has secured $325 million from New York State for Phase I of an effort to redesign, renovate and update 12 existing schools. Later phases will address the …

Vaccine Access And Affordability In A Coordinated Market Under Stochastic Reservation Prices, Galo Mosquera Dec 2015

Vaccine Access And Affordability In A Coordinated Market Under Stochastic Reservation Prices, Galo Mosquera

Theses

Ensuring vaccine affordability and accessibility are major challenges for the fulfillment of the immunization goals of the Global Vaccine Action Plan for the decade 2011 – 2020. Four of the five immunization goals in this plan are currently delayed because of limitations in vaccine affordability. The use of combination vaccines can help to make vaccines more accessible as long as their pricing becomes more affordable. Procurement mechanisms, such as tiered pricing and pooled procurement, have generally been used for reducing the cost of vaccine purchases, but they have not been used to ensure overall market affordability. This study extends the …

A Synthetic Lethality Screen Using A Focused Sirna Library To Identify Sensitizers To Dasatinib Therapy For The Treatment Of Epithelial Ovarian Cancer., Harsh B Pathak, Yan Zhou, Geetika Sethi, Jeff Hirst, Russell J Schilder, Erica A Golemis, Andrew K Godwin

Department of Medicine Faculty Papers

Molecular targeted therapies have been the focus of recent clinical trials for the treatment of patients with recurrent epithelial ovarian cancer (EOC). The majority have not fared well as monotherapies for improving survival of these patients. Poor bioavailability, lack of predictive biomarkers, and the presence of multiple survival pathways can all diminish the success of a targeted agent. Dasatinib is a tyrosine kinase inhibitor of the Src-family kinases (SFK) and in preclinical studies shown to have substantial activity in EOC. However, when evaluated in a phase 2 clinical trial for patients with recurrent or persistent EOC, it was found to …

Endometrial Stromal Sarcoma Metastatic From The Uterus To The Inferior Vena Cava And Right Atrium, Daniel Scher, William Nghiem, Salim Aziz, Rodeen Rahbar, Whitney Banks, Anthony Venbrux, Shawn Sarin

The Texas Heart Institute Journal

Endometrial stromal sarcoma metastases usually occur within the pelvis and rarely involve the great vessels or the heart. We present the case of a 55-year-old woman who was referred for endovascular therapy to treat presumed thrombosis of the inferior vena cava. The suspected thrombus was recalcitrant to endovascular removal with use of an AngioVac venous drainage device. Results of an intraprocedural transvenous biopsy revealed the mass to be the intravascular extension of an endometrial stromal sarcoma. The patient underwent surgical excision of the tumor, and, shortly thereafter, a hysterectomy and salpingo-oophorectomy. This complex case highlights both the rarity of malignancy …

Microaxial Flow Left Ventricular Assist Device As A Bridge To Transplantation After Lvad Malfunction, Heidi J Reich, Aamir Shah, Babak Azarbal, Jon Kobashigawa, Jaime Moriguchi, Lawrence Czer, Fardad Esmailian

The Texas Heart Institute Journal

Evolving technology and improvements in the design of modern, continuous-flow left ventricular assist devices have substantially reduced the rate of device malfunction. As the number of implanted devices increases and as survival prospects for patients with a device continue to improve, device malfunction is an increasingly common clinical challenge. Here, we present our initial experience with an endovascular microaxial flow left ventricular assist device as a successful bridge to transplantation in a 54-year-old man who experienced left ventricular assist device malfunction.


The Intersection Of Civil And Religious Family Law In The U.S. Constitutional Order: A Mild Legal Pluralism, Linda C. Mcclain Dec 2015

The Intersection Of Civil And Religious Family Law In The U.S. Constitutional Order: A Mild Legal Pluralism, Linda C. Mcclain

Faculty Scholarship

This chapter considers how civil and religious family law intersect in the U.S. legal system and how U.S. constitutional law shapes and constrains the accommodation of religious pluralism as it pertains to family law. To the question, “Is there too much or too little pluralism in U.S. family law?,” I answer that family law appropriately embraces a mild legal pluralism, while clearly distinguishing between civil and religious marriage. After illustrating this distinction in the context of the recent controversy over same-sex marriage, I consider two categories of cases: (1) cases in which courts consider whether to enforce terms of Jewish …

Resurrecting Health Care Rate Regulation, Erin C. Fuse Brown Dec 2015

Resurrecting Health Care Rate Regulation, Erin C. Fuse Brown

UC Law Journal

Our excess health care spending in the United States is driven largely by our high health care prices. Our prices are so high because they are undisciplined by market forces, in a health care system rife with market failures, which include information asymmetries, noncompetitive levels of provider market concentration, moral hazard created by health insurance, multiple principal-agent relationships with misaligned incentives, and externalities from unwarranted price variation and discrimination. These health care market failures invite a regulatory solution. An array of legal and policy solutions are typically advanced to control our health care prices and spending, including: (1) market solutions …

Intraventricular Sialidase Administration Enhances Gm1 Ganglioside Expression And Is Partially Neuroprotective In A Mouse Model Of Parkinson's Disease., Jay S Schneider, Thomas N Seyfried, Hyo-S Choi, Sarah Kidd

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Preclinical and clinical studies have previously shown that systemic administration of GM1 ganglioside has neuroprotective and neurorestorative properties in Parkinson's disease (PD) models and in PD patients. However, the clinical development of GM1 for PD has been hampered by its animal origin (GM1 used in previous studies was extracted from bovine brains), limited bioavailability, and limited blood brain barrier penetrance following systemic administration.

OBJECTIVE: To assess an alternative therapeutic approach to systemic administration of brain-derived GM1 to enhance GM1 levels in the brain via enzymatic conversion of polysialogangliosides into GM1 and to assess the neuroprotective potential of this approach. …

When 1 + 1 > 2: Nanostructured Composites For Hard Tissue Engineering Applications, Vuk Uskoković

Pharmacy Faculty Articles and Research

Multicomponent, synergistic and multifunctional nanostructures have taken over the spotlight in the realm of biomedical nanotechnologies. The most prospective materials for bone regeneration today are almost exclusively composites comprising two or more components that compensate for the shortcomings of each one of them alone. This is quite natural in view of the fact that all hard tissues in the human body, except perhaps the tooth enamel, are composite nanostructures. This review article highlights some of the most prospective breakthroughs made in this research direction, with the hard tissues in main focus being those comprising bone, tooth cementum, dentin and enamel. …


Genome Rearrangements Can Make And Break Small Rna Genes, Rahul Raghavan, Fenil R. Kacharia, Jess A. Millar, Christine Demko Sislak, Howard Ochman Dec 2015

Genome Rearrangements Can Make And Break Small Rna Genes, Rahul Raghavan, Fenil R. Kacharia, Jess A. Millar, Christine Demko Sislak, Howard Ochman

Biology Faculty Publications and Presentations

Small RNAs (sRNAs) are short, transcribed regulatory elements that are typically encoded in the intergenic regions (IGRs) of bacterial genomes. Several sRNAs, first recognized in Escherichia coli, are conserved among enteric bacteria, but because of the regulatory roles of sRNAs, differences in sRNA repertoires might be responsible for features that differentiate closely related species. We scanned the E. coli MG1655 and Salmonella enterica Typhimurium genomes for nonsyntenic IGRs as a potential source of uncharacterized, species-specific sRNAs and found that genome rearrangements have reconfigured several IGRs causing the disruption and formation of sRNAs. Within an IGR that is present in …


Energy-Environment Policy Alignments, Todd S. Aagaard Dec 2015

Energy-Environment Policy Alignments, Todd S. Aagaard

Faculty Publications

Energy law focuses on making energy widely available at reasonable cost, and environmental law focuses on preventing pollution. As a result of these differences in their respective orientations, the two fields often work incoherently and even in conflict. Historically, federal energy law and environmental law have attempted to manage their interrelationships by imposing negative constraints on each other: Energy policies of the Federal Energy Regulatory Commission (FERC) must comply with requirements set forth in environmental statutes, and the Environmental Protection Agency’s (EPA’s) statutes contain energy-related requirements and exemptions. More recently, however, FERC and EPA have begun developing policies that create …


Special Needs Children And Mental Health, Nancy J. Carbonell Dec 2015

Special Needs Children And Mental Health, Nancy J. Carbonell

Faculty Publications

What do these stories have in common? They are representative of many students who experience learning difficulties while at the same time struggling with mental or emotional issues. Special-needs teachers see children like Brandon, Carmen, and Jake in their classrooms every day. It is estimated that in the U.S., 37 percent of children with special needs also need mental-health care. That is approximately one in every three special-needs students! This is particularly challenging for teachers whose training did not include how to deal with children experiencing mental-health issues.

A Pedagogy Of Inquiry, Nicole Pagowsky Dec 2015

A Pedagogy Of Inquiry, Nicole Pagowsky

Communications in Information Literacy

Library instruction continues to evolve. Regardless of the myriad and conflicting opinions academic librarians have about the ACRL Framework for Information Literacy, the debates and the document itself have engendered greater discourse surrounding how and why librarians teach. The Framework provides an additional push toward designing instruction with big ideas rather than a skills-based curriculum. However, we still must contend with constraints imposed upon us by higher education taking on business models and enforcing a skills agenda. To enact the pedagogy of the Framework in contrast to changes in higher education presents a challenge. We should consider ways in which …

Tunneling A Pulmonary Artery Graft: A Simplified Way To Insert And Remove A Temporary Right Ventricular Assist Device, Pankaj Saxena, Silvana F Marasco Dec 2015

Tunneling A Pulmonary Artery Graft: A Simplified Way To Insert And Remove A Temporary Right Ventricular Assist Device, Pankaj Saxena, Silvana F Marasco

The Texas Heart Institute Journal

Right ventricular failure can occur early or late after left ventricular assist device implantation. Support with a right ventricular assist device is needed in patients whose right ventricular failure does not respond to conservative management. The use of a temporary right ventricular assist device can enable the recovery of right ventricular function and avoid the use of a more permanent biventricular assist device, which is associated with complications and higher costs. We present our technique of instituting temporary right ventricular assist device support in patients who have undergone left ventricular assist device implantation.

Multivariate Criteria Most Accurately Distinguish Cardiac From Noncardiac Causes Of Dyspnea, Mirza Nubair Ahmad, Syed Hasan Yusuf, Rafath Ullah, Mirza Mujadil Ahmad, Mary K Ellis, Haroon Yousaf, Timothy E Paterick, Khawaja Afzal Ammar

The Texas Heart Institute Journal

Cardiopulmonary exercise testing provides oxygen pulse as a continuous measure of stroke volume, which is superior to other stress-testing methods in which systolic function is measured at baseline and at peak stress. However, the optimal peak oxygen pulse criterion for distinguishing cardiac from noncardiac causes of exercise limitation is unknown.

In comparing several peak oxygen pulse criteria against the clinical standard of cardiopulmonary exercise testing, we retrospectively studied 54 consecutive patients referred for cardiopulmonary exercise testing. These exercise tests included measurement of oxygen consumption, carbon dioxide production, breathing reserve, arterial blood gases at baseline and at peak stress, exercise electrocardiogram, …
