Sultan Qaboos University Medical Journal

Objectives: Dimethyl fumarate (DMF) is known to cause lymphopenia when used to treat patients with multiple sclerosis (MS). However, research on DMF therapy in the Arab world, especially in Oman, is scarce. This study aimed to analyse the prevalence of lymphopenia among Omani patients with MS and their reasons for discontinuing DMF therapy. Methods: In this retrospective study, the medical records of Omani patients with MS who were treated using DMF at two tertiary hospitals in Muscat, Oman, from February 2017 to February 2023 were reviewed. Their demographic, clinical and laboratory data were retrieved and analysed. Absolute lymphocyte count values …

Covid-19 Infection Increases The Development Of Stevens-Johnson Syndrome And Toxic Epidermal Necrolysis: A Retrospective Cohort Analysis, Kristen K. Curtis, Meghan M. Dillan, Timmie R. Sharma, Joseph Piktel

Student Scholarship

To the Editor: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) represent a spectrum of severe mucocutaneous reactions characterized by extensive epidermal detachment, most commonly due to medications.1 Some viruses, such as the human immunodeficiency virus, have been found to be an independent risk factor for the development of SJS and TEN, though the mechanism is not completely understood.2 Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus identified in late 2019, is most commonly associated with mild respiratory illness. However, cutaneous manifestations, including SJS and TEN, have been increasingly reported during and after COVID-19 infection.3 Therefore, the objective …

Androgen Drives Melanoma Invasiveness And Metastatic Spread By Inducing Tumorigenic Fucosylation, Qian Liu

USF Tampa Graduate Theses and Dissertations

Melanoma incidence and mortality rates are historically higher for men than women, with an estimated ~47% more new cases and twice the lethality in men in the US in 2023. Consistent with these discrepancies, emerging studies have highlighted the tumorigenic role of the male sex hormone androgen and its receptor (AR) in promoting melanoma aggressiveness. However, underlying cellular and molecular mechanisms and their precise pathological contributions are not well-defined. We recently discovered a sex-associated disparity in melanoma fucosylation, the post-translational modification of proteins with the dietary sugar L-fucose. Fucosylation, the conjugation of fucose moieties onto different glycan linkages on target …

Energetic Trade-Offs In Migration Decision-Making, Reproductive Effort And Subsequent Parental Care In A Long-Distance Migratory Bird, Alexander R Schindler, Anthony D Fox, Christopher K Wikle, Bart M Ballard, Alyn J Walsh, Seán B A Kelly, Lei Cao, Larry R Griffin, Mitch D Weegman

Faculty, Staff and Student Publications

Migratory species trade-off long-distance movement with survival and reproduction, but the spatio-temporal scales at which these decisions occur are relatively unknown. Technological and statistical advances allow fine-scale study of animal decision-making, improving our understanding of possible causes and therefore conservation management. We quantified effects of reproductive preparation during spring migration on subsequent breeding outcomes, breeding outcomes on autumn migration characteristics and autumn migration characteristics on subsequent parental survival in Greenland white-fronted geese (

Macromolecular Crowding, Phase Separation, And Homeostasis In The Orchestration Of Bacterial Cellular Functions, Begoña Monterroso, William Margolin, Arnold J Boersma, Germán Rivas, Bert Poolman, Silvia Zorrilla

Faculty, Staff and Student Publications

Macromolecular crowding affects the activity of proteins and functional macromolecular complexes in all cells, including bacteria. Crowding, together with physicochemical parameters such as pH, ionic strength, and the energy status, influences the structure of the cytoplasm and thereby indirectly macromolecular function. Notably, crowding also promotes the formation of biomolecular condensates by phase separation, initially identified in eukaryotic cells but more recently discovered to play key functions in bacteria. Bacterial cells require a variety of mechanisms to maintain physicochemical homeostasis, in particular in environments with fluctuating conditions, and the formation of biomolecular condensates is emerging as one such mechanism. In this …

Causal Influence Of Linguistic Learning On Perceptual And Conceptual Processing: A Brain-Constrained Deep Neural Network Study Of Proper Names And Category Terms, Phuc T U Nguyen, Malte R Henningsen-Schomers, Friedemann Pulvermüller

Faculty, Staff and Student Publications

Language influences cognitive and conceptual processing, but the mechanisms through which such causal effects are realized in the human brain remain unknown. Here, we use a brain-constrained deep neural network model of category formation and symbol learning and analyze the emergent model's internal mechanisms at the neural circuit level. In one set of simulations, the network was presented with similar patterns of neural activity indexing instances of objects and actions belonging to the same categories. Biologically realistic Hebbian learning led to the formation of instance-specific neurons distributed across multiple areas of the network, and, in addition, to cell assembly circuits …

Experience With A Hybrid Recruitment Approach Of Patient-Facing Web Portal Screening And Subsequent Phone And Medical Record Review For A Neurosurgical Intervention Trial For Chronic Ischemic Stroke Disability (Pisces Iii), Brad J Kolls, Keith W Muir, Sean I Savitz, Lawrence R Wechsler, Julie G Pilitsis, Scott Rahimi, Richard L Beckman, Vincent Holmes, Peng R Chen, David S Albers, Daniel T Laskowitz

Faculty, Staff and Student Publications

BACKGROUND: Recruitment of participants is the greatest risk to completion of most clinical trials, with 20-40% of trials failing to reach the targeted enrollment. This is particularly true of trials of central nervous system (CNS) therapies such as intervention for chronic stroke. The PISCES III trial was an invasive trial of stereotactically guided intracerebral injection of CTX0E03, a fetal derived neural stem cell line, in patients with chronic disability due to ischemic stroke. We report on the experience using a novel hybrid recruitment approach of a patient-facing portal to self-identify and perform an initial screen for general trial eligibility (tier …

Iterative Patient Testing Of A Stimuli-Responsive Swallowing Activity Sensor To Promote Extended User Engagement During The First Year After Radiation: Multiphase Remote And In-Person Observational Cohort Study, Eileen H Shinn, Adam S Garden, Susan K Peterson, Dylan J Leupi, Minxing Chen, Rachel Blau, Laura Becerra, Tarek Rafeedi, Julian Ramirez, Daniel Rodriquez, Finley Vanfossen, Sydney Zehner, Patrick P Mercier, Joseph Wang, Kate Hutcheson, Ehab Hanna, Darren J Lipomi

Faculty, Staff and Student Publications

BACKGROUND: Frequent sensor-assisted monitoring of changes in swallowing function may help improve detection of radiation-associated dysphagia before it becomes permanent. While our group has prototyped an epidermal strain/surface electromyography sensor that can detect minute changes in swallowing muscle movement, it is unknown whether patients with head and neck cancer would be willing to wear such a device at home after radiation for several months.

OBJECTIVE: We iteratively assessed patients' design preferences and perceived barriers to long-term use of the prototype sensor.

METHODS: In study 1 (questionnaire only), survivors of pharyngeal cancer who were 3-5 years post treatment and part of …

Ramsay Hunt Syndrome Associated With Varicella-Zoster Virus Encephalitis In A Child, Eman Y. Ahmed, Hatem Al Rawahi, Fatema Al Amrani, Laila Al Masaoudi, Laila Al Yazidi

Sultan Qaboos University Medical Journal

Ramsay Hunt syndrome (RHS) is a triad of peri-auricular pain, ipsilateral facial nerve palsy and vesicular rash around the ear pinna. It is caused by reactivation of varicella-zoster virus (VZV) that lies dormant in the geniculate ganglia. It can be complicated by VZV encephalitis rarely. We report the case of an 8-year-old previously healthy boy who presented to a tertiary care hospital in Muscat, Oman in 2021 with fever, progressive left ear pain, vesicular rash around his ear pinna and left-sided facial nerve palsy. His course was complicated by VZV encephalitis where he was managed with intravenous (IV) acyclovir and …

Stat5 Induces Androgen Receptor (Ar) Gene Transcription In Prostate Cancer And Offers A Druggable Pathway To Target Ar Signaling, Cristina Maranto, Lavannya Sabharwal, Vindhya Udhane, Samuel P. Pitzen, Braedan Mccluskey, Songyan Qi, Christine O'Connor, Savita Devi, Scott Johnson, Kenneth Jacobsohn, Anjishnu Banerjee, Kenneth A. Iczkowski, Liang Wang, Scott M. Dehm, Marja T. Nevalainen

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Androgen receptor (AR) drives prostate cancer (PC) growth and progression, and targeting AR signaling is the mainstay of pharmacological therapies for PC. Resistance develops relatively fast as a result of refueled AR activity. A major gap in the field is the lack of understanding of targetable mechanisms that induce persistent AR expression in castrate-resistant PC (CRPC). This study uncovers an unexpected function of active Stat5 signaling, a known promoter of PC growth and clinical progression, as a potent inducer of AR gene transcription. Stat5 suppression inhibited AR gene transcription in preclinical PC models and reduced the levels of wild-type, mutated, …

Scurvy: A Rare Disease Or A Rare Diagnosis?, David F. Gaieski

Department of Emergency Medicine Faculty Papers

Introduction:

Scurvy, the disease state caused by ascorbic acid deficiency, was once an extremely common disease but is now thought to be a rare disease in postmodern societies. Physicians are not trained to consider scurvy as a possible diagnosis in patients at risk; rather, it is considered a rare diagnosis to add to a differential for completeness’s sake.

Methods:

We sought to describe the scorbutic patients seen by one physician during a busy academic emergency medicine career. Case series of patients seen by one physician between 1993 and 2023 at five academic teaching hospitals with Emergency Departments (EDs) in the …

Epigenome-Wide Association Study Identifies Neonatal Dna Methylation Associated With Two-Year Attention Problems In Children Born Very Preterm., Marie Camerota, Barry M. Lester, Francisco Xavier Castellanos, Brian S. Carter, Jennifer Check, Jennifer Helderman, Julie A. Hofheimer, Elisabeth C. Mcgowan, Charles R. Neal, Steven L. Pastyrnak, Lynne M. Smith, Thomas Michael O'Shea, Carmen J. Marsit, Todd M. Everson

Manuscripts, Articles, Book Chapters and Other Papers

Prior research has identified epigenetic predictors of attention problems in school-aged children but has not yet investigated these in young children, or children at elevated risk of attention problems due to preterm birth. The current study evaluated epigenome-wide associations between neonatal DNA methylation and attention problems at age 2 years in children born very preterm. Participants included 441 children from the Neonatal Neurobehavior and Outcomes in Very Preterm Infants (NOVI) Study, a multi-site study of infants born < 30 weeks gestational age. DNA methylation was measured from buccal swabs collected at NICU discharge using the Illumina MethylationEPIC Bead Array. Attention problems were assessed at 2 years of adjusted age using the attention problems subscale of the Child Behavior Checklist (CBCL). After adjustment for multiple testing, DNA methylation at 33 CpG sites was associated with child attention problems. Differentially methylated CpG sites were located in genes previously linked to physical and mental health, including several genes associated with ADHD in prior epigenome-wide and genome-wide association studies. Several CpG sites were located in genes previously linked to exposure to prenatal risk factors in the NOVI sample. Neonatal epigenetics measured at NICU discharge could be useful in identifying preterm children at risk for long-term attention problems and related psychiatric disorders, who could benefit from early prevention and intervention efforts.

Simple Summary

Bladder cancer (BCa) is a major urologic malignancy with a high potential for death-threatening complications. Successful treatment relies on timely diagnostics and prediction of clinical outcomes. Molecular markers can be helpful for earlier diagnosis and for making treatment decisions. The biomarker landscape for BCa is not satisfactory yet. The discovery of novel diagnostic indicators for making treatment decisions is critical. Biological fluids are the most convenient and reliable source of these molecules. Circular RNAs (CircRNAs), special non-coding RNAs with a stable structure that are formed by a unique backsplicing process, recently became popular candidates for biomarkers in cancer …

Knee Flexion Angle Of Fixation During Anterolateral Ligament Reconstruction Or Lateral Extra-Articular Tenodesis: A Systematic Review And Meta-Analysis Of Lateral Extra-Articular Reinforcement Techniques Performed In Conjunction With Acl Reconstruction, David A Kolin, Jeffrey J Nepple, Et Al.

2020-Current year OA Pubs

BACKGROUND: Anterolateral ligament reconstruction (ALLR) or lateral extra-articular tenodesis (LET) is being used more frequently in conjunction with anterior cruciate ligament reconstruction (ACLR). However, the knee flexion angle at which fixation of ALLR or LET is performed during the procedure is quite variable based on existing technique descriptions.

PURPOSE/HYPOTHESIS: The purpose of this study was to identify whether flexion angle at the time of ALLR/LET fixation affected postoperative outcomes in a clinical population. It was hypothesized that ALLR/LET fixation at low versus high flexion angles would lead to no statistically significant differences in patient-reported outcome measures and graft failure rates. …

Hmzdupfinder: A Robust Computational Approach For Detecting Intragenic Homozygous Duplications From Exome Sequencing Data, Haowei Du, Zain Dardas, Angad Jolly, Christopher M Grochowski, Shalini N Jhangiani, He Li, Donna Muzny, Jawid M Fatih, Gozde Yesil, Nursel H Elçioglu, Alper Gezdirici, Dana Marafi, Davut Pehlivan, Daniel G Calame, Claudia M B Carvalho, Jennifer E Posey, Tomasz Gambin, Zeynep Coban-Akdemir, James R Lupski

Homozygous duplications contribute to genetic disease by altering gene dosage or disrupting gene regulation and can be more deleterious to organismal biology than heterozygous duplications. Intragenic exonic duplications can result in loss-of-function (LoF) or gain-of-function (GoF) alleles that when homozygosed, i.e. brought to homozygous state at a locus by identity by descent or state, could potentially result in autosomal recessive (AR) rare disease traits. However, the detection and functional interpretation of homozygous duplications from exome sequencing data remains a challenge. We developed a framework algorithm, HMZDupFinder, that is designed to detect exonic homozygous duplications from exome sequencing (ES) data. The …

Current And Emerging Antiviral Agents In The Prevention And Treatment Of Cytomegalovirus In Pediatric Transplant Recipients, Kristen G Valencia Deray, Lara A Danziger-Isakov, Kevin J Downes

Faculty, Staff and Students Publications

Despite current prophylaxis regimens, cytomegalovirus (CMV) is common in hematopoietic cell transplantation (HCT) and solid organ transplantation (SOT) and remains a significant cause of morbidity and mortality. Newer antiviral medications are reshaping the landscape for prevention and treatment of CMV DNAemia, infection, and disease. Letermovir is approved for CMV prevention in adult HCT patients and is attractive due to the absence of marrow suppression seen with ganciclovir/valganciclovir. Letermovir should not be routinely used for CMV treatment due to its low threshold for resistance. Maribavir is approved for the treatment of refractory or resistant CMV disease in HCT and SOT recipients …

Rrm3 And Pif1 Division Of Labor During Replication Through Leading And Lagging Strand G-Quadruplex, Mor Varon, Daniel Dovrat, Jonathan Heuzé, Ioannis Tsirkas, Saurabh P Singh, Philippe Pasero, Roberto Galletto, Amir Aharoni

2020-Current year OA Pubs

Members of the conserved Pif1 family of 5'-3' DNA helicases can unwind G4s and mitigate their negative impact on genome stability. In Saccharomyces cerevisiae, two Pif1 family members, Pif1 and Rrm3, contribute to the suppression of genomic instability at diverse regions including telomeres, centromeres and tRNA genes. While Pif1 can resolve lagging strand G4s in vivo, little is known regarding Rrm3 function at G4s and its cooperation with Pif1 for G4 replication. Here, we monitored replication through G4 sequences in real time to show that Rrm3 is essential for efficient replisome progression through G4s located on the leading strand template, …

A Case Of Siadh After Bowel Preparation For Routine Colonoscopy, Joseph C. Rath, Allison M. Hemmer, Kennedy A. Forest, Kahlen R. Morris, Mary E. Watson

Aesculapius Journal (Health Sciences & Medicine)

Electrolyte abnormalities, including hyponatremia, are a known outcome of bowel preparations used for colonoscopy. Severe and symptomatic hyponatremia after bowel preparation is uncommon and occurs due to excessive release of ADH among other contributing factors. Risk factors for developing hyponatremia after bowel preparation include increased age, female gender, kidney disease, heart failure, and use of various medications. We present the case of a 78-year-old female who presented with altered mental status and possible seizures after completing bowel preparation with polyethylene glycol for a colonoscopy. Serum and urine studies were consistent with SIADH. She required fluid restriction, hypertonic saline, and sodium …

3-Chloropropylbis(Catecholato)Silicate As A Bifunctional Reagent For The One-Pot Synthesis Of Tetrahydroquinolines From O-Bromosulfonamides, Noah Brodsky, Nidheesh Phadnis, Mohamed Ibrahim, Isabel M. Andino, Inés Blanc Giro, John A. Milligan

College of Life Sciences Faculty Papers

Bis(catecholato)silicate salts are easily accessible reagents that can be used to install alkyl fragments through photoredox-enabled cross-coupling. These reagents can incorporate various functional groups including pendant alkyl halides. A halogenated organosilicate reagent was leveraged to develop a one-pot synthesis of tetrahydroquinolines from o-bromosulfonamides, where the bifunctional reagent participates in a nickel/photoredox cross-coupling followed by intramolecular nucleophilic substitution. The functional group tolerance of this cross-coupling strategy allowed for the preparation of a series of substituted tetrahydroquinolines.

Population Health Research Brief Series

Infant mortality rates are higher in the United States than in its high-income peer countries. Additionally, infant mortality rates vary within the U.S., with much higher rates in some geographic regions compared to others. This data slice uses data from the U.S. Centers for Disease Control and Prevention to compare infant mortality rates by geographic region in the U.S. between 2017-2021. The results show that the infant mortality rate was the highest in the South and lowest in the Northeast and West.

Protein-Folding Chaperones Predict Structure-Function Relationships And Cancer Risk In Brca1 Mutation Carriers, Brant Gracia, Patricia Montes, Angelica Maria Gutierrez, Banu Arun, Georgios Ioannis Karras

Faculty, Staff and Student Publications

Predicting the risk of cancer mutations is critical for early detection and prevention, but differences in allelic severity of human carriers confound risk predictions. Here, we elucidate protein folding as a cellular mechanism driving differences in mutation severity of tumor suppressor BRCA1. Using a high-throughput protein-protein interaction assay, we show that protein-folding chaperone binding patterns predict the pathogenicity of variants in the BRCA1 C-terminal (BRCT) domain. HSP70 selectively binds 94% of pathogenic BRCA1-BRCT variants, most of which engage HSP70 more than HSP90. Remarkably, the magnitude of HSP70 binding linearly correlates with loss of folding and function. We identify a prevalent …

Gamma Delta T Cells In Acute Myeloid Leukemia: Biology And Emerging Therapeutic Strategies, Adishwar Rao, Akriti Agrawal, Gautam Borthakur, Venkata Lokesh Battula, Abhishek Maiti

Faculty, Staff and Student Publications

γδ T cells play an important role in disease control in acute myeloid leukemia (AML) and have become an emerging area of therapeutic interest. These cells represent a minor population of T lymphocytes with intrinsic abilities to recognize antigens in a major histocompatibility complex-independent manner and functionally straddle the innate and adaptive immunity interface. AML shows high expression of phosphoantigens and UL-16 binding proteins that activate the Vδ2 and Vδ1 subtypes of γδ T cells, respectively, leading to γδ T cell-mediated cytotoxicity. Insights from murine models and clinical data in humans show improved overall survival, leukemia-free survival, reduced risk of …

Hypomethylating agents (HMAs) and venetoclax (Ven) represent the standard of care for patients with acute myeloid leukemia (AML) who are ineligible for intensive chemotherapy. However, the European LeukemiaNet (ELN) risk classifications have been validated for patients treated with intensive therapy. In this study, we validate a recently proposed new molecular prognostic risk signature (mPRS) for patients with AML treated with HMAs and Ven. This classification allocated patients to favorable, intermediate (N/KRAS or FLT3-internal tandem duplication mutations), and lower (TP53 mutations) benefit groups. We retrospectively analyzed 159 patients treated with HMA and Ven. The mPRS classification allocated 74 (47%), 31 (19%), …
