The Relationship Between Malignant Tumors And Ischemic Stroke: Ii. Chronology Of Diagnoses And Treatment Of Strokes, Nóra Hajnóczky, Dániel Bereczki

Department of Medicine Faculty Papers

Összefoglaló. A malignus daganatok és a stroke együttesen gyakran fordulnak elő a stroke tradicionális rizikófaktoraival (magas vérnyomás, hyperlipidaemia, cukorbetegség, elhízás, dohányzás) rendelkező betegekben. Az elmúlt évtized kutatási eredményei alátámasztották, hogy a rosszindulatú daganatban szenvedő betegekben szignifikánsan nagyobb a stroke kockázata. A malignus daganatokhoz társuló stroke a leggyakrabban a malignus daganat diagnózisát követő fél-egy év során jelentkezik. A kapcsolat a másik irányban is létezik: stroke-betegek követése során malignus daganat szignifikánsan gyakrabban jelent meg, mint a stroke-mentes kontrollcsoportban. A daganatot a leginkább a stroke utáni első hat hónapban diagnosztizálják. A korábban nem ismert rosszindulatú daganat időnként az akut stroke kezelése során derül …

Department of Radiology Faculty Papers

Mild traumatic brain injury (mTBI) is a major public health concern that can result in a broad spectrum of short-term and long-term symptoms. Recently, machine learning (ML) algorithms have been used in neuroscience research for diagnostics and prognostic assessment of brain disorders. The present study aimed to develop an automatic classifier to distinguish patients suffering from chronic mTBI from healthy controls (HCs) utilizing multilevel metrics of resting-state functional magnetic resonance imaging (rs-fMRI). Sixty mTBI patients and forty HCs were enrolled and allocated to training and testing datasets with a ratio of 80:20. Several rs-fMRI metrics including fractional amplitude of low-frequency …

Droplet Precautions On-Site (Drops) During The Influenza Season 2018/2019: A Possible Alternative To Single Room Isolation For Respiratory Viral Infections, Michèle Birrer, Martin Perrig, Fabienne Hobi, Christina Gfeller, Andrew Atkinson, Martin Egger, Corinne Bartholdi, Drahomir Aujesky, Jonas Marschall, Rami Sommerstein

2020-Current year OA Pubs

BACKGROUND: The guideline-driven and widely implemented single room isolation strategy for respiratory viral infections (RVI) such as influenza or respiratory syncytial virus (RSV) can lead to a shortage of available hospital beds. We discuss our experience with the introduction of droplet precautions on-site (DroPS) as a possible alternative.

METHODS: During the 2018/19 influenza season we introduced DroPS on several wards of a single tertiary care center, while other wards maintained the traditional single room isolation strategy. On a daily basis, we evaluated patients for the development of respiratory symptoms and screened those with a clinical diagnosis of hospital-acquired respiratory viral …

Tumor-associated macrophages (TAMs) promote progression of breast cancer and other solid malignancies via immunosuppressive, pro-angiogenic and pro-metastatic effects. Tumor-promoting TAMs tend to express M2-like macrophage markers, including CD163. Histopathological assessments suggest that the density of CD163-positive TAMs within the tumor microenvironment is associated with reduced efficacy of chemotherapy and unfavorable prognosis. However, previous analyses have required research-oriented pathologists to visually enumerate CD163+ TAMs, which is both laborious and subjective and hampers clinical implementation. Objective, operator-independent image analysis methods to quantify TAM-associated information are needed. In addition, since M2-like TAMs exert local effects on cancer cells through direct juxtacrine cell-to-cell interactions, …

A Qualitative Study On Pharmacy Policies Toward Over-The-Counter Syringe Sales In A Rural Epicenter Of Us Drug-Related Epidemics, Monica Fadanelli, Hannah L. F. Cooper, Patricia R. Freeman, April M. Ballard, Umed Ibragimov, April M. Young

Pharmacy Practice and Science Faculty Publications

BACKGROUND: Expanding access to sterile syringes in rural areas is vital, as injection-related epidemics expand beyond metropolitan areas globally. While pharmacies have potential to be an easily accessible source of sterile syringes, research in cities has identified moral, legal and ethical barriers that preclude over-the-counter (OTC) sales to people who inject drugs (PWID). The current study builds on prior urban-based research by elucidating (1) pharmacy OTC policies and (2) pharmacists' rationale for, and barriers and facilitators to, OTC syringe sales in a US rural area hard hit by drug-related epidemics.

METHODS: We conducted 14 semi-structured interviews with pharmacists recruited from …

Pharmacy Faculty Articles and Research

Small- and intermediate-conductance Ca²⁺-activated potassium (K_Ca2.x and K_Ca3.1, also called SK and IK) channels are activated exclusively by a Ca²⁺-calmodulin gating mechanism. Wild-type K_Ca2.3 channels have a Ca²⁺ EC₅₀ value of ∼0.3 μM, while the apparent Ca²⁺ sensitivity of wild-type K_Ca3.1 channels is ∼0.27 μM. Heterozygous genetic mutations of K_Ca2.3 channels have been associated with Zimmermann-Laband syndrome and idiopathic noncirrhotic portal hypertension, while K_Ca3.1 channel mutations were reported in hereditary xerocytosis patients. K_Ca2.3_S436C and K_Ca2.3_V450L channels with …

A Rare Case Of A Middle Ear Glomangioma., Margaret E. Wieser, David R. Gilley, Jason G. May, Arnaldo L. Rivera

Manuscripts, Articles, Book Chapters and Other Papers

Glomus tumors are benign hyperplasia of glomus bodies, and they are rarely found in the head and neck. The middle ear is an exceptionally rare site for a true glomus tumor, and there are only three previously reported cases in this location. Glomus tumors are etiologically different than glomus tympanicum, which are paragangliomas of the middle ear that are often mistakenly referred to as "glomus tumors." This is a common misconception due to the "glomus" misnomer. We report a case of a patient diagnosed with a middle ear glomangioma after initially presenting to our clinic with tinnitus and hearing loss. …

Impact Of Medicaid Expansion On Interpregnancy Interval, Can Lui, Jonathan Snowden, Maya Rossin-Slater, Florencia Torche, Julia D. Ditosto, Suzan L. Carmichael

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objectives

Medicaid expansion under the Affordable Care Act (ACA) improved access to reproductive health care for low-income women and birthing people who were previously ineligible for Medicaid. We aimed to evaluate if the expansion affected the risk of having a short interpregnancy interval (IPI), a preventable risk factor for adverse pregnancy outcomes.

Methods

We evaluated parous singleton births to mothers aged 19 or older from U.S. birth certificate data 2009–2018. We estimated the effect of residing in a state that expanded Medicaid access (expansion status determined at 60 days after the prior live birth) on the risk of having a …

Using A Stochastic Continuous-Time Markov Chain Model To Examine Alternative Timing And Duration Of The Covid-19 Lockdown In Kuwait: What Can Be Done Now?, Mustafa Al-Zoughool, Tamer Oraby, Harri Vainio, Janvier Gasana, Joseph C. Longenecker, Walid Al Ali, Mohammad Alseaidan, Susie Elsaadany, Michael G. Tyshenko

School of Mathematical & Statistical Sciences Faculty Publications

Background

Kuwait had its first COVID-19 in late February, and until October 6, 2020 it recorded 108,268 cases and 632 deaths. Despite implementing one of the strictest control measures-including a three-week complete lockdown, there was no sign of a declining epidemic curve. The objective of the current analyses is to determine, hypothetically, the optimal timing and duration of a full lockdown in Kuwait that would result in controlling new infections and lead to a substantial reduction in case hospitalizations.

Methods

The analysis was conducted using a stochastic Continuous-Time Markov Chain (CTMC), eight state model that depicts the disease transmission and …

Loss-Of-Function Mutation In Pcsk1 Increases Serum Apoa1 Level And Lcat Activity In Mice., Aleksandra Aljakna Khan, Nakyung Kim, Ron Korstanje, Seungbum Choi

Faculty Research 2022

BACKGROUND: The convertase subtilisin/kexin family 1 gene (PCSK1) has been associated in various human genetics studies with a wide spectrum of metabolic phenotypes, including early-onset obesity, hyperphagia, diabetes insipidus, and others. Despite the evident influence of PCSK1 on obesity and the known functions of other PCSKs in lipid metabolism, the role of PCSK1 specifically in lipid and cholesterol metabolism remains unclear. This study evaluated the effect of loss of PCSK1 function on high-density lipoprotein (HDL) metabolism in mice.

RESULTS: HDL cholesterol, apolipoprotein A1 (APOA1) levels in serum and liver, and the activities of two enzymes (lecithin-cholesterol acyltransferase, LCAT and phospholipid …

Targeting Dnmts To Overcome Enzalutamide Resistance In Prostate Cancer, Elia Farah, Zhuangzhuang Zhang, Sagar M. Utturkar, Jinpeng Liu, Timothy L. Ratliff, Xiaoqi Liu

Toxicology and Cancer Biology Faculty Publications

Prostate cancer is the second leading cause of cancer death among men in the United States. The androgen receptor (AR) antagonist enzalutamide is an FDA-approved drug for treatment of patients with late-stage prostate cancer and is currently under clinical study for early-stage prostate cancer treatment. After a short positive response period to enzalutamide, tumors will develop drug resistance. In this study, we uncovered that DNA methylation was deregulated in enzalutamide-resistant cells. DNMT activity and DNMT3B expression were upregulated in resistant cell lines. Enzalutamide induced the expression of DNMT3A and DNMT3B in prostate cancer cells with a potential role of p53 …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

The global coronavirus disease-2019 (COVID-19) pandemic has changed the prevalence and management of many pediatric infectious diseases, including acute otitis media (AOM). Coronaviruses are a group of RNA viruses that cause respiratory tract infections in humans. Before the COVID-19 pandemic, coronavirus serotypes OC43, 229E, HKU1, and NL63 were infrequently detected in middle ear fluid (MEF) specimens and nasopharyngeal aspirates in children with AOM during the 1990s and 2000s and were associated with a mild course of the disease. At times when CoV was detected in OM cases, the overall viral load was relatively low. The new severe acute respiratory syndrome …
