Ototoxicity Of Topical Antibiotic Ear Drops In Chronic Suppurative Otitis Media In Humans: A Review Of The Literature, Syed Zohaib Maroof Hussain, Syed S Hashmi, Asad Qayyum

Faculty, Staff and Student Publications

An electronic search of the literature was performed for reported cases of ototoxicity associated with the use of topical antibiotic ear drops in humans. The dosage, duration, and type of ototoxic preparations involved were recorded. Due to the scant quantity of low-quality information that is currently available, there was uncertainty about the usefulness of topical antibiotics in enhancing the resolution of ear discharge in patients with chronic suppurative otitis media. However, despite this uncertainty, there are some data to show that using topical antibiotics in comparison to a placebo or in conjunction with a systemic antibiotic may be useful. Additionally, …

We describe a small molecule ligand ACA-14 (2-hydroxy-5-{[(2-phenylcyclopropyl) carbonyl] amino} benzoic acid) as an initial lead for the development of direct inhibitors of KRAS, a notoriously difficult anticancer drug target. We show that the compound binds to KRAS near the switch regions with affinities in the low micromolar range and exerts different effects on KRAS interactions with binding partners. Specifically, ACA-14 impedes the interaction of KRAS with its effector Raf and reduces both intrinsic and SOS-mediated nucleotide exchange rates. Likely as a result of these effects, ACA-14 inhibits signal transduction through the MAPK pathway in cells expressing mutant KRAS and …

The Microbial Etiology Of Community-Acquired Pneumonia In Adults: From Classical Bacteriology To Host Transcriptional Signatures, Naomi J Gadsby, Daniel M Musher

Faculty, Staff and Students Publications

All modern advances notwithstanding, pneumonia remains a common infection with substantial morbidity and mortality. Understanding of the etiology of pneumonia continues to evolve as new techniques enable identification of already known organisms and as new organisms emerge. We now review the etiology of pneumonia (at present often called "community-acquired pneumonia") beginning with classic bacteriologic techniques, which identified Streptococcus pneumoniae as the overwhelmingly common cause, to more modern bacteriologic studies, which emphasize Haemophilus influenzae, Staphylococcus aureus, Moraxella catarrhalis,

Nebraska Center for Virology: Faculty Publications

Antimicrobial resistance (AMR) is a global problem facing human, animal, plant, and environmental health by threatening our ability to effectively treat bacterial infections with antimicrobials. In the United States, robust surveillance efforts exist to collect, analyze, and disseminate AMR data in human health care settings. These tools enable the development of effective infection control methods, the detection of trends, and provide the evidence needed to guide stewardship efforts to reduce the potential for emergence and further spread of AMR. However, in veterinary medicine, there are currently no known equivalent tools. This paper reviews efforts to reduce the potential for emergence …

Does Receiving A Sars-Cov-2 Antibody Test Result Change Covid-19 Protective Behaviors? Testing Risk Compensation In Undergraduate Students With A Randomized Controlled Trial, Christina Ludema, Molly S Rosenberg, Jonathan T Macy, Sina Kianersi, Maya Luetke, Chen Chen, Lilian Golzarri-Arroyo, Erin Ables, Kevin Maki, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: Risk compensation, or matching behavior to a perceived level of acceptable risk, can blunt the effectiveness of public health interventions. One area of possible risk compensation during the SARS-CoV-2 pandemic is antibody testing. While antibody tests are imperfect measures of immunity, results may influence risk perception and individual preventive actions. We conducted a randomized control trial to assess whether receiving antibody test results changed SARS-CoV-2 protective behaviors.

Purpose: Assess whether objective information about antibody status, particularly for those who are antibody negative and likely still susceptible to SARS-CoV-2 infection, increases protective behaviors. Secondarily, assess whether a positive antibody test …

A Flexible-Hazards Cure Model With Application To Patients With Soft Tissue Sarcoma, Can Xie, Xuelin Huang, Ruosha Li, Peter W T Pisters

Faculty, Staff and Student Publications

In medical research, it is often of great interest to have an accurate estimation of cure rates by different treatment options and for different patient groups. If the follow-up time is sufficiently long and the sample size is large, the proportion of cured patients will make the Kaplan-Meier estimator of survival function have a flat plateau at its tail, whose value indicates the overall cure rate. However, it may be difficult to estimate and compare the cure rates for all the subsets of interest in this way, due to the limit of sample sizes and curse of dimensionality. In the …

Progressive Acceleration Of Insulin Exposure Over 7 Days Of Infusion Set Wear, Jasmin R. Kastner, Timothy S. Bailey, Poul Strange, Leon Shi, Keith A. Oberg, Paul J. Strasma, Jeffrey I. Joseph, Douglas B. Muchmore

Department of Anesthesiology Faculty Papers

Insulin exposure varies over 3 days of insulin infusion set (IIS) wear making day-to-day insulin dosing challenging for people with diabetes (PWD). Here we report insulin pharmacodynamic (PD) and pharmacokinetic (PK) data extending these observations to 7 days of IIS wear. PWD (A1C ≤8.5%, C-peptide tmax (P < 0.001), Cmax (P < 0.05), and mean residence time (P < 0.0001). Area under the insulin concentration curve (AUC0–300) declined by ∼24% from days 0 to 7 (P < 0.05). These results confirm/extend previous observations showing progressive acceleration of insulin exposure over IIS wear time. This may have implications for PWD and designers of closed-loop algorithms, although larger studies are necessary to confirm this. The study was registered in clinicaltrials.gov (NCT04398030).

Xcvatr: Detection And Characterization Of Variant Impact On The Embeddings Of Single -Cell And Bulk Rna-Sequencing Samples, Arif Harmanci, Akdes Serin Harmanci, Tiemo J Klisch, Akash J Patel

Duncan NRI Faculty and Staff Publications

Background: RNA-sequencing has become a standard tool for analyzing gene activity in bulk samples and at the single-cell level. By increasing sample sizes and cell counts, this technique can uncover substantial information about cellular transcriptional states. Beyond quantification of gene expression, RNA-seq can be used for detecting variants, including single nucleotide polymorphisms, small insertions/deletions, and larger variants, such as copy number variants. Notably, joint analysis of variants with cellular transcriptional states may provide insights into the impact of mutations, especially for complex and heterogeneous samples. However, this analysis is often challenging due to a prohibitively high number of variants and …

In-Depth Analysis Of Alternative Splicing Landscape In Multiple Myeloma And Potential Role Of Dysregulated Splicing Factors, Anil Aktas Samur, Mariateresa Fulciniti, Herve Avet-Loiseau, Michael A Lopez, Sanika Derebail, Jill Corre, Stephane Minvielle, Florence Magrangeas, Philippe Moreau, Kenneth C Anderson, Giovanni Parmigiani, Mehmet K Samur, Nikhil C Munshi

Faculty, Staff and Student Publications

Splicing changes are common in cancer and are associated with dysregulated splicing factors. Here, we analyzed RNA-seq data from 323 newly diagnosed multiple myeloma (MM) patients and described the alternative splicing (AS) landscape. We observed a large number of splicing pattern changes in MM cells compared to normal plasma cells (NPC). The most common events were alterations of mutually exclusive exons and exon skipping. Most of these events were observed in the absence of overall changes in gene expression and often impacted the coding potential of the alternatively spliced genes. To understand the molecular mechanisms driving frequent aberrant AS, we …

Faculty, Staff and Student Publications

BACKGROUND: The benefits and challenges of successful breastfeeding for both mother and child have been well-established in the literature. While ankyloglossia, or tongue tie, alone or in combination with upper lip tie has been the focus of several previous studies, very few have directly addressed isolated symptomatic upper lip tie and the role of surgical correction for breastfeeding difficulties.

MATERIALS AND METHODS: Seven infants with isolated upper lip tie and breastfeeding difficulty were taken to the operating room for labial frenotomy. These infants were assessed at their follow-up visits for their degree of weight gain since their procedure. Their mothers …

Structural Insights Into Cardiolipin Replacement By Phosphatidylglycerol In A Cardiolipin-Lacking Yeast Respiratory Supercomplex, Elena G Govorunova, Oleg A Sineshchekov, Leonid S Brown, Ana-Nicoleta Bondar, John L Spudich

Faculty, Staff and Student Publications

Potassium-selective channelrhodopsins (KCRs) are light-gated K+ channels recently found in the stramenopile protist Hyphochytrium catenoides. When expressed in neurons, KCRs enable high-precision optical inhibition of spiking (optogenetic silencing). KCRs are capable of discriminating K+ from Na+ without the conventional K+ selectivity filter found in classical K+ channels. The genome of H. catenoides also encodes a third paralog that is more permeable for Na+ than for K+. To identify structural motifs responsible for the unusual K+ selectivity of KCRs, we systematically analyzed a series of chimeras and mutants of this protein. We found that mutations of three critical residues in the …

Tumor-infiltrating lymphocytes (TILs), especially CD8+ TILs, represent a favorable prognostic factor in high-grade serous ovarian cancer (HGSOC) and other tumor lineages. Here, we analyze the spatial heterogeneity of different TIL subtypes in HGSOC. We integrated RNA sequencing, whole-genome sequencing, bulk T cell receptor (TCR) sequencing, as well as single-cell RNA/TCR sequencing to investigate the characteristics and differential composition of TILs across different HGSOC sites. Two immune "cold" patterns in ovarian cancer are identified: (1) ovarian lesions with low infiltration of mainly dysfunctional T cells and immunosuppressive Treg cells and (2) omental lesions infiltrated with non-tumor-specific bystander cells. Exhausted CD8 T …

Antibody Epitope Profiling Of The Kshv Lana Protein Using Virscan, Sydney J. Bennett, Dicle Yalcin, Sara R. Privatt, Owen Ngalamika, Salum J. Lidenge, John T. West, Charles Wood

School of Medicine Faculty Publications

The humoral antibody response against Kaposi sarcoma-associated herpesvirus (KSHV) in infected individuals has been characterized demonstrating the latency-associated nuclear antigen (LANA) as the most antigenic KSHV protein. Despite the antigenicity of the protein, specific LANA epitopes have not been systematically characterized. Here, we utilized a bacteriophage T7 library, which displays 56-amino acid KSHV LANA peptides with 28-amino acid overlap (VirScan), to define those epitopes in LANA targeted by antibodies from a cohort of 62 sub-Saharan African Kaposi Sarcoma (KS) patients and 22 KSHV-infected asymptomatic controls. Intra- and inter-patient breadth and magnitude of the anti-LANA responses were quantified at the peptide …

The Role Of Lncrnas In The Tumor Microenvironment And Immunotherapy Of Melanoma, Wencheng Zhou, Xuewen Xu, Ying Cen, Junjie Chen

Faculty, Staff and Student Publications

Melanoma is one of the most lethal tumors with highly aggressive and metastatic properties. Although immunotherapy and targeted therapy have certain therapeutic effects in melanoma, a significant proportion of patients still have drug resistance after treatment. Recent studies have shown that long noncoding RNAs (lncRNAs) are widely recognized as regulatory factors in cancer. They can regulate numerous cellular processes, including cell proliferation, metastasis, epithelial-mesenchymal transition (EMT) progression and the immune microenvironment. The role of lncRNAs in malignant tumors has received much attention, whereas the relationship between lncRNAs and melanoma requires further investigation. Our review summarizes tumor suppressive and oncogenic lncRNAs …

Accumulation Of Sublethal Radiation Damage And Its Effect On Cell Survival, Oleg N Vassiliev

Faculty, Staff and Student Publications

Objective. Determine the extent of sublethal radiation damage (SRD) in a cell population that received a given dose of radiation and the impact of this damage on cell survival. Approach. We developed a novel formalism to account for accumulation of SRD with increasing dose. It is based on a very general formula for cell survival that correctly predicts the basic properties of cell survival curves, such as the transition from the linear-quadratic to a linear dependence at high doses. Using this formalism we analyzed extensive experimental data for photons, protons and heavy ions to evaluate model parameters, quantify the extent …

How To Manage The Initiation Of Apomorphine Therapy Without Antiemetic Pretreatment: A Review Of The Literature, Stuart H. Isaacson, Richard B. Dewey, Rajesh Pahwa, Daniel E. Kremens

Department of Neurology Faculty Papers

Introduction

Pretreatment with the antiemetic trimethobenzamide has been recommended practice in the United States (US) to address the risk of nausea and vomiting during initiation of apomorphine treatment. However, trimethobenzamide is no longer being manufactured in the US, and despite the recent update to the US prescribing information, there may be uncertainty regarding how to initiate apomorphine.

Methods

To better understand why antiemetic pretreatment was recommended and if it is necessary when initiating apomorphine therapy, we performed a literature review of subcutaneous apomorphine therapy initiation with and without antiemetic pretreatment in patients with PD.

Results

Three studies were identified as …

Stabilization Of Mcl-1 By E3 Ligase Traf4 Confers Radioresistance, Ming Li, Feng Gao, Xiaoying Li, Yu Gan, Shuangze Han, Xinfang Yu, Haidan Liu, Wei Li

Faculty, Staff and Students Publications

The E3 ligase TNF receptor-associated factor 4 (TRAF4) is frequently overexpressed and closely related to poor prognosis in human malignancies. However, its effect on carcinogenesis and radiosensitivity in oral squamous cell carcinoma (OSCC) remains unclear. The present study found that TRAF4 was significantly upregulated in primary and relapsed OSCC tumor tissues. Depletion of TRAF4 markedly improved the sensitivity of OSCC cells to irradiation (IR) treatment, showing that tumor cell proliferation, colony formation and xenograft tumor growth were reduced. Mechanistically, IR promoted the interaction between TRAF4 and Akt to induce Akt K63-mediated ubiquitination and activation. TRAF4 knockout inhibited the phosphorylation of …

Reflecting On The Advancements Of Hfref Therapies Over The Last Two Decades And Predicting What Is Yet To Come, Iliana L. Piña, Gregory T. Gibson, Shelley Zieroth, Rachna Kataria

Division of Cardiology Faculty Papers

What was once considered a topic best avoided, managing heart failure with reduced ejection fraction (HFrEF) has become the focus of many drug and device therapies. While the four pillars of guideline-directed medical therapies have successfully reduced heart failure hospitalizations, and some have even impacted cardiovascular mortality in randomized controlled trials (RCTs), patient-reported outcomes have emerged as important endpoints that merit greater emphasis in future studies. The prospect of an oral inotrope seems more probable now as targets for drug therapies have moved from neurohormonal modulation to intracellular mechanisms and direct cardiac myosin stimulation. While we have come a long …

Real-time US fusion imaging of the liver is gaining more acceptance as it enables further …

A Forehead Wearable Sensor For The Objective Measurement Of Chronic Pain, Marcus Orzabal, Ramo Naidu, Kasra Amirdelfan, Alireza Akhbardeh

Faculty, Staff and Student Publications

Chronic pain impacts one in five Americans and is difficult to manage, costing ~USD 600 billion annually. The subjective experience of pain is a complex processing of central nervous system input. Recent advances in magnetic resonance imaging revealed the prefrontal cortex as vital to the perception of pain and that changes in the cerebral hemodynamics can be used to detect painful sensations. Current pain monitoring is dependent on the subjective rating provided by patients and is limited to a single time point. We have developed a biomarker for the objective, real-time and continuous chronic pain assessment using proprietary algorithms termed …
