Comparison Of Two Lipid Emulsions On The Incidence Of Parenteral Nutrition Associated Cholestasis In Neonates, Joy Greenberg, Mamta Naik, John Chapman, Allison Davidson, Essam Imseis

Faculty, Staff and Student Publications

OBJECTIVE: Lipid emulsion contributes to parenteral nutrition associated cholestasis (PNAC). For decades, soybean oil-based intravenous lipid emulsion (SO-ILE) was the predominant product. Recently, a multicomponent lipid emulsion containing soybean oil, medium-chain triglycerides, olive oil and fish oil (SMOF-ILE) has been used off-label in neonatal care. This study evaluates the incidence of PNAC in neonates who received SMOF-ILE or SO-ILE.

METHODS: This was a retrospective review of neonates who received SMOF-ILE or SO-ILE for at least 14 days. Patients receiving SMOF-ILE were matched based on gestational age (GA) and birth weight to a historical cohort receiving SO-ILE. The primary outcomes were …

Use Of Elamipretide In Patients Assigned Treatment In The Compassionate Use Program: Case Series In Pediatric Patients With Rare Orphan Diseases, Mary Kay Koenig, Sam Nick Russo, Kim L Mcbride, Hans Tomas Bjornsson, Brynja Bjork Gunnarsdottir, Amy Goldstein, Scott A Falk

Faculty, Staff and Student Publications

Several mitochondrial diseases are caused by pathogenic variants that impair membrane phospholipid remodeling, with no FDA-approved therapies. Elamipretide targets the inner mitochondrial membrane where it binds to cardiolipin, resulting in improved membrane stability, cellular respiration, and ATP production. In clinical trials, elamipretide produced clinical and functional improvements in adults and adolescents with mitochondrial disorders, such as primary mitochondrial myopathy and Barth syndrome; however, experience in younger patients is limited and to our knowledge, these are the first case reports on the safety and efficacy of elamipretide treatment in children under 12 years of age. We describe the use of elamipretide …

The Development Of Tumour Vascular Networks, Cassandra B Iroz, Willemijn L A Schäfer, Julie K Johnson, Meagan S Ager, Reiping Huang, Salva N Balbale, Jonah J Stulberg

Faculty, Staff and Student Publications

BACKGROUND: Opioids prescribed to treat postsurgical pain have contributed to the ongoing opioid epidemic. While opioid prescribing practices have improved, most patients do not use all their pills and do not safely dispose of leftovers, which creates a risk for unsafe use and diversion. We aimed to generate consensus on the content of a "safe opioid use agreement" for the perioperative settings to improve patients' safe use, storage, and disposal of opioids.

METHODS: We conducted a modified three-round Delphi study with clinicians across surgical specialties, quality improvement (QI) experts, and patients. In Round 1, participants completed a survey rating the …

Utilizing 10khz Stimulation To Salvage A Failed Low Frequency Spinal Cord Stimulation Trial, Jamal Hasoon, Christopher Robinson, Ivan Urits, Omar Viswanath, Alan D Kaye

Faculty, Staff and Student Publications

Spinal cord stimulation (SCS) is a viable treatment option for chronic pain. One of the primary indications for SCS implantation is persistent pain after spinal surgery. Studies have demonstrated that these patients have a better response to SCS over conservative management or repeat surgery. Traditional SCS therapy uses parasthesias to overlap a patient's pain pattern and provide relief, though some patients find this uncomfortable. To avoid the use of paresthesias, a 10kHz waveform can be utilized to provide a subthreshold level of high frequency stimulation to provide superior pain relief without paresthesias. Additionally, 10kHz stimulation may be used to salvage …

Faculty, Staff and Student Publications

Purpose of review: Lower back pain (LBP) has a lifetime prevalence of 80% in the United States population. Discogenic back pain (DBP), a subcategory of LBP, occurs as a result of the interverbal disc degeneration without disc herniation. Diagnosis relies on history, physical exam, and imaging such as MRI, provocative discography, or CT discography.

Recent findings: Treatment of DBP involves a multifaceted approach with an emphasis on conservative measures including behavioral modification, pharmacologic management, and other non-pharmacologic interventions with invasive therapy reserved for select patients. Due to the paucity of data on the treatment of DBP, treatment also relies on …

Burning Mouth Syndrome Treated With Mandibular And Maxillary Nerve Blocks, Jamal Hasoon, Christopher Robinson, Ivan Urits, Omar Viswanath, Alan D Kaye

Faculty, Staff and Student Publications

Burning mouth syndrome is a condition characterized by a painful burning sensation in the oral mucosa lasting at least 3-6 months with no definitive etiology. The pathophysiology is not well understood, though there appears to be a connection with other neuropsychiatric conditions such as depression, anxiety, and mood disorders. We briefly discuss our experience with a patient who suffered from this conidtion and how it was treated with mandibular and maxillary nerve blocks after failing more conservative pharmacological options.

Sex-Biased Autophagy As A Potential Mechanism Mediating Sex Differences In Ischemic Stroke Outcome, Brian Noh, Louise D Mccullough, Jose F Moruno-Manchon

Faculty, Staff and Student Publications

Stroke is the second leading cause of death and a major cause of disability worldwide, and biological sex is an important determining factor in stroke incidence and pathology. From childhood through adulthood, men have a higher incidence of stroke compared with women. Abundant research has confirmed the beneficial effects of estrogen in experimental ischemic stroke but genetic factors such as the X-chromosome complement can also play an important role in determining sex differences in stroke. Autophagy is a self-degrading cellular process orchestrated by multiple core proteins, which leads to the engulfment of cytoplasmic material and degradation of cargo after autophagy …

An F-Ratio-Based Method For Estimating The Number Of Active Sources In Meg, Amita Giri, John C Mosher, Amir Adler, Dimitrios Pantazis

Faculty, Staff and Student Publications

INTRODUCTION: Magnetoencephalography (MEG) is a powerful technique for studying the human brain function. However, accurately estimating the number of sources that contribute to the MEG recordings remains a challenging problem due to the low signal-to-noise ratio (SNR), the presence of correlated sources, inaccuracies in head modeling, and variations in individual anatomy.

METHODS: To address these issues, our study introduces a robust method for accurately estimating the number of active sources in the brain based on the F-ratio statistical approach, which allows for a comparison between a full model with a higher number of sources and a reduced model with fewer …

Development Of A Methodology For Large-Scale Production Of Prions For Biological And Structural Studies, Luis Concha-Marambio, Fei Wang, Enrique Armijo, Damian Gorski, Frank Ramirez, Andrew Scowcroft, Sandra Pritzkow, Claudio Soto

Faculty, Staff and Student Publications

Prion diseases are a group of infectious neurodegenerative diseases produced by the conversion of the normal prion protein (PrP^C) into the disease-associated form (PrP^Sc). Extensive evidence indicate that the main or sole component of the infectious agent is PrP^Sc, which can replicate in affected individuals in the absence of nucleic acids. However, the mechanism of PrP^C-to-PrP^Sc conversion remains elusive, which has been attributed to the lack of sufficient structural information of infectious PrP^Sc and a reliable system to study prion replication in vitro. In this article we adapted the …

Aβ Plaques Do Not Protect Against Hsv-1 Infection In A Mouse Model Of Familial Alzheimer’S Disease, And Hsv-1 Does Not Induce Aβ Pathology In A Model Of Late Onset Alzheimer’S Disease, Olga V Bocharova, Aidan Fisher, Narayan P Pandit, Kara Molesworth, Olga Mychko, Alison J Scott, Natallia Makarava, Rodney Ritzel, Ilia V Baskakov

Faculty, Staff and Student Publications

The possibility that the etiology of late onset Alzheimer's disease is linked to viral infections of the CNS has been actively debated in recent years. According to the antiviral protection hypothesis, viral pathogens trigger aggregation of Aβ peptides that are produced as a defense mechanism in response to infection to entrap and neutralize pathogens. To test the causative relationship between viral infection and Aβ aggregation, the current study examined whether Aβ plaques protect the mouse brain against Herpes Simplex Virus 1 (HSV-1) infection introduced via a physiological route and whether HSV-1 infection triggers formation of Aβ plaques in a mouse …

Faculty, Staff and Student Publications

The recent development of a system for long-term in vitro culture of the syphilis spirochete, Treponema pallidum subsp. pallidum, has introduced the possibility of detailed genetic analysis of this bacterium. In this study, the in vitro culture system was used to isolate and characterize clonal populations of T. pallidum subsp. pallidum Nichols, the most widely studied strain. In limiting dilutions experiments, it was possible to establish cultures with inocula as low as 0.5 T. pallidum per well despite the long generation time (~35 to 40 hours) of this organism. Six Nichols strain clones isolated by limiting dilution were characterized in …

A Large Screen Identifies Beta-Lactam Antibiotics Which Can Be Repurposed To Target The Syphilis Agent, Kathryn A Hayes, Jules M Dressler, Steven J Norris, Diane G Edmondson, Brandon L Jutras

Faculty, Staff and Student Publications

Syphilis, caused by the spirochete Treponema pallidum subsp. pallidum (hereafter called T. pallidum), is re-emerging as a worldwide sexually transmitted infection. A single intramuscular dose of benzathine penicillin G is the preferred syphilis treatment option. Both supply shortage concerns and the potential for acquired antibiotic resistance further the need to broaden the repertoire of syphilis therapeutics. We reasoned that other β-lactams may be equally or more effective at targeting the disease-causing agent, Treponema pallidum, but have yet to be discovered due to a previous lack of a continuous in vitro culture system. Recent technical advances with respect to …
