Goal-Directed Haemodynamic Therapy Improves Patient Outcomes In Kidney Transplantation, J Fabes, Midani A Al, As Sarna, Dh Hadi, Sa Naji, Nr Banga, Gl Jones, Pd Berry, Md Wittenberg

Peninsula Medical School

Introduction: Kidney transplant graft function depends on optimised haemodynamics. However, high fluid volumes risk hypervolaemic complications. The Edwards Lifesciences ClearSight™ device permits fluid titration through markers of preload and beat-to-beat blood pressure monitoring. We evaluated the implementation of a novel goal-directed haemodynamic therapy protocol to determine whether patient outcomes had improved. Design: A retrospective evaluation of standard care versus goal-directed haemodynamic therapy in adults undergoing kidney transplantation was performed in a single centre between April 2016 and October 2019. Twenty-eight standard-of-care patients received intraoperative fixed-rate infusion and 28 patients received goal-directed haemodynamic therapy. The primary outcome was volume of fluid …

This study involved examining relations between adolescent rejection sensitivity and anxiety and whether they were moderated by problem-solving skills, an indicator of resiliency, as well as gender. Theoretical frameworks in this study were the rejection sensitivity model and resilience theory. This …

Nursing Knowledge And Breastfeeding Education, Mary Aguirre Jan 2023

Nursing Knowledge And Breastfeeding Education, Mary Aguirre

Walden Dissertations and Doctoral Studies

According to the Centers for Disease Control and Prevention, the Healthy People 2020 breastfeeding goal immediately after birth of 81.9% was surpassed in 2016, with approximately 83.8% of babies breastfed shortly after delivery. However, by seven days post birth, this number decreased to 82.9%, reduced even more for infants who were exclusively breastfed to 64.7%. Local research has shown that breastfeeding decreases at one week after discharge, which may be due, in part, to the lack of nurses' knowledge related to breastfeeding. This lack of knowledge related to breastfeeding by the nurses, in turn, may negatively impact the support staff …

Right Treatment Wrong Time: Immunotherapy Administration Post-Radiotherapy Decreases Tumor Burden In A Preclinical Model Of Brain Metastasis, Kathryn Elizabeth Blethen Jan 2023

Right Treatment Wrong Time: Immunotherapy Administration Post-Radiotherapy Decreases Tumor Burden In A Preclinical Model Of Brain Metastasis, Kathryn Elizabeth Blethen

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation (a) provided an in-depth literature review of methods to modulate the blood-brain and blood-tumor barriers to increase drug delivery and efficacy in brain metastases, (b) evaluated the effects of whole-brain radiation therapy on the blood-brain barrier in immunocompetent and immunocompromised mouse models and proposed a mechanism by which the immune response to radiation disrupts the blood-brain barrier, and (c) developed a syngeneic lung cancer brain metastasis model to determine the impact of coordinated immunotherapy administration with radiotherapy. The blood-brain barrier is an impediment to drug delivery to the brain. The inherent leakiness of the blood-tumor barrier does not …

Glial Cell-Specific Contribution Of Pkr-Like Er Kinase (Perk) In Neuroinflammation And Behavior, Anirudhya Lahiri Jan 2023

Glial Cell-Specific Contribution Of Pkr-Like Er Kinase (Perk) In Neuroinflammation And Behavior, Anirudhya Lahiri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neurological disorders such as multiple sclerosis (MS) are a major public health concern in the US, with no available therapeutic cure. Chronic neuroinflammation and aberrant proteostasis in the central nervous system (CNS) are the major hallmarks of neurological diseases. Endoplasmic Reticulum (ER) is a major cellular organelle involved in protein synthesis, folding and maturation of various secretory and transmembrane proteins. Pathophysiological stressors such as trauma and infection result in misfolded protein accumulation in the endoplasmic reticulum (ER) lumen, which results in ER stress. To regain proteostasis (protein homeostasis), cells activate the unfolded protein response (UPR). UPR is an evolutionarily conserved …

Scientific Guidelines For Evaluating The Validity Of Forensic Feature-Comparison Methods, David L. Faigman, Nicholas Scurich, Thomas D. Albright Jan 2023

Scientific Guidelines For Evaluating The Validity Of Forensic Feature-Comparison Methods, David L. Faigman, Nicholas Scurich, Thomas D. Albright

Faculty Scholarship

When it comes to questions of fact in a legal context— particularly questions about measurement, association, and causality—courts should employ ordinary standards of applied science. Applied sciences generally develop along a path that proceeds from a basic scientific discovery about some natural process to the formation of a theory of how the process works and what causes it to fail, to the development of an invention intended to assess, repair, or improve the process, to the specification of predictions of the instrument’s actions and, finally, empirical validation to determine that the instrument achieves the intended effect. These elements are salient …

Federal Nonenforcement At A Crossroads, Zachary Price Jan 2023

Federal Nonenforcement At A Crossroads, Zachary Price

Faculty Scholarship

As a novel aspect of “presidential administration”—the president- centered approach to federal governance discussed in a 2001 article by then-Professor and future Supreme Court Justice Elena Kagan—broad federal nonenforcement policies have been a major source of controversy in the past decade. As illustrated by the Obama Administration’s ex- pansive nonenforcement policies relating to marijuana, immigration, and Affordable Care Act implementation, recent presidents have recog- nized nonenforcement’s potential to reshape statutory law to suit an administration’s policy aims. This Article takes stock of this develop- ment as it relates to the past three presidential administrations. While advocating a limited view of …

A Trip To The Border: Legal History And Apa Originalism, Reuel E. Schiller Jan 2023

A Trip To The Border: Legal History And Apa Originalism, Reuel E. Schiller

Faculty Scholarship

This article examines originalist interpretations of the Administrative Procedure Act (APA) from the perspective of a legal historian. After ex­ amining two pieces of originalist scholarship, it concludes that the histor­ ical record may not produce narratives of enough specificity or coherence to assist the originalist project. Nonetheless, it highlights three under-examined subjects of historical inquiry that have the most potential to aid APA originalists: the nature of administrative procedure during the first three decades of the twentieth century when the modem "appellate model" of judicial review emerged; the actual practice of ad­ ministrative law during the New Deal, both …

Suing Spacs, Emily Strauss

Faculty Scholarship

In 2020, the financial world became transfixed by a massive increase in the number of firms going public through special purpose acquisition company (“SPAC”) transactions. A SPAC is a publicly traded company formed solely for the purpose of raising money from investors and choosing a merger partner, thereby bringing the target company public. SPAC shareholders vote on the proposed transaction, but also have the option to redeem their shares for the price paid plus interest prior to the merger. SPACs have always been controversial; they make risky ventures available to unsophisticated investors, may involve acute conflicts of interest, and do …

Rewarding Failure With Patents, Robin Feldman Jan 2023

Rewarding Failure With Patents, Robin Feldman

Faculty Scholarship

It is axiomatic that patents promote success. And yet, a contrary notion—that the patent incentive for medicine should be sufficient to compensate for the losses incurred when other research fails—is quietly permeating modern court decisions, commentary, and Congressional discussions, coloring debates relating to pricing and regulation of medicine. The conceptualization is moving forward unchallenged, as if failure compensation follows logically from the innovation incentives built into the patent construct. As this Article demonstrates, however, the notion is antithetical to patent law, putting modern conceptualizations on a collision course with the history and theory of patents reaching back to this nation’s …
