Training In Medications For Opioid Use Disorder And Buprenorphine Prescribing In The Post X-Waiver Era: Insights From A Nationwide, Multispecialty Survey, Sung In H Kim-Vences, Justin Nguyen, Jacqueline M Hirth, Kyle P Suen, Colleen A Keough, Roger Zoorob, Alicia A Kowalchuk

Faculty, Staff and Students Publications

Objective: The January 2023 repeal of the X-waiver aimed to reduce regulatory barriers to buprenorphine prescribing and enhance patient access to medications for opioid use disorder (MOUD). Its impact on prescribing by non-addiction-trained physicians, the integration of MOUD training into residency programs, and the role of mandated training on clinical practice remain unclear.

Methods: A 2024 online survey assessed physicians' awareness of the X-waiver repeal, exposure to MOUD training, and changes in buprenorphine prescribing. Multivariable logistic regression evaluated the independent effect of MOUD training and whether mandatory versus voluntary formats influenced prescribing behavior.

Results: Among 959 physicians (42.7 % residents), …

Technical Considerations And Contemporary Literature Review Of The Gore Thoracic Branch Endoprosthesis®, Bruno P Schmid, Lucas R Kanamori, Hannah V Oden-Brunson, Dora Babocs, Ying Huang, Jorge Miranda, Steven Maximus, Gustavo S Oderich

Faculty, Staff and Students Publications

Thoracic endovascular aortic repair (TEVAR) has become the preferred treatment for various thoracic aortic pathologies, including blunt thoracic aortic injury, aneurysms, and dissections. Involvement of Ishimaru Zone 2 occurs in up to 60% of TEVAR cases requiring extension across the distal aortic arch and left subclavian artery (LSA). Coverage of the LSA without revascularization increases the risk of complications such as upper extremity ischemia, stroke, and spinal cord injury. Therefore, the preservation of LSA perfusion during TEVAR is essential. Cervical debranching remains an effective alternative to preserve flow to the LSA, but it poses risks of bleeding, infection, and nerve …

Urinary Biomarkers Of Acute Kidney Injury In Neonates < 25 Weeks’ Gestation: A Pilot Study, Jazmin D Humphreys, Aman Jain, Amir M Khan, Tina O Findley, Mar Romero-Lopez, Sepideh Saroukhani, Rita D Swinford, Matthew A Rysavy

Faculty, Staff and Student Publications

Background: Acute kidney injury (AKI) occurs in 30% of premature neonates and is associated with adverse outcomes that may be mitigated with early detection. Diagnosis of AKI relies on serum creatinine (SCr) which has several limitations, including lack of sensitivity and specificity. There are limited data on the utility of alternative urine biomarkers to predict AKI in neonates born at < 25 weeks' gestation.

Methods: Urine was collected from neonates born at < 25 weeks' gestation during the first postnatal week. Two urine AKI biomarkers, neutrophil gelatinase-associated lipocalin (NGAL) and epidermal growth factor (EGF) were measured. Study participants were prospectively followed to determine development of AKI, defined by the neonatal modified Kidney Disease-Improving Global Outcomes (KDIGO) criteria, during the first postnatal week. The association of NGAL and EGF with AKI was analyzed using mixed-effect linear regression models adjusting for gestational age at birth.

Results: A total of 26 neonates were enrolled in this study. After adjusting for gestational age at birth, the mean difference in log-transformed biomarkers at three time points for urine NGAL and …

Background: It remains unclear whether outcomes of patients treated with endovascular thrombectomy with large-vessel occlusion and unwitnessed onset of stroke differ from those with witnessed onset in the extended time window.

Methods: We enrolled patients with anterior circulation large-vessel occlusion (internal carotid artery, M1, or M2 segment of the middle cerebral artery) undergoing endovascular thrombectomy within 6 to 24 hours from the time last seen well, from 2014 to 2022, at 66 sites in Europe, North America, and Asia. Patients with a prestroke modified Rankin Scale score of >3 or age < 18 were excluded. We categorized patients by onset mode as witnessed or unwitnessed. The primary outcome was the modified Rankin Scale shift at 90 days. Secondary outcomes were functional independence, a composite of functional independence or return of Rankin to prestroke level, symptomatic intracranial hemorrhage, mortality, and a composite of severe disability or mortality at 90 days. We applied inverse probability of treatment weighting to compare outcomes between the groups.

Results: Of 5098 patients assessed for eligibility, we included …

Bayesian Posthoc Trial Analysis Of Cerclage Management In Preterm Prelabor Rupture Of The Membranes, Beth L Pineles, Kyung Hyun Lee, Baha M Sibai

Faculty, Staff and Student Publications

Background: There is inadequate evidence on whether to retain or remove a cervical cerclage after preterm prelabor rupture of the membranes (PPROM). The PROMCerclage trial was the only study to randomize patients to cerclage retention or immediate cerclage removal after PPROM. The trial was terminated early, and results were not statistically significant but the cerclage retention group had shorter latency and more chorioamnionitis. Bayesian post-hoc trial analysis maximizes available clinical trial data by formally integrating information from preexisting studies or prior beliefs into statistical modeling to estimate the probability of a treatment effect.

Objective: To re-analyze published results of the …

Medical aid in dying (MAiD) is a practice in which a healthcare professional provides assistance to a terminally ill patient seeking to end their life. To assess how academic discourse may shape public opinion and policy in the United States, we conducted a narrative review of the literature published between 2020 and 2024. Articles were categorized as supportive, opposing, or neutral, and patterns were examined across authorship, disciplinary focus, and target populations. Our findings reveal that most recent publications adopt supportive or neutral stances toward MAiD, with a slight increase in opposition beginning in 2022. Authorship discipline strongly influenced position, …

Therapeutic Potential Of C1-Inhibitor In Vascular Diseases And Beyond, Linda Sundler Björkman, Harish Eswaran, Steven P Grover

Faculty, Staff and Student Publications

C1INH (C1-inhibitor) is a multifunctional SERPIN (serine protease inhibitor) that functions as a major negative regulator of the complement, coagulation, and kallikrein-kinin systems. C1INH products were originally developed for the treatment of hereditary angioedema associated with C1INH deficiency. A growing body of literature indicates that C1INH products may find utility in the management of several other disease states. In this review, we detail the key biological activities of C1INH and consider the pathophysiological role of C1INH targets in many conditions. The therapeutic potential of exogenous C1INH is highlighted in the settings of thromboembolism, ischemia-reperfusion injury, sepsis, transplantation, and coronavirus disease …

Cressent: A Bioinformatics Toolkit To Explore And Improve Ssdna Virus Annotation, Ricardo R Pavan, Matthew B Sullivan, Michael J Tisza

Faculty, Staff and Students Publications

ssDNA viruses are important components of diverse ecosystems; however, it remains challenging to systematically identify and classify them. This is partly due to their broad host range and resulting genomic diversity, structure and rapid evolutionary rates. In addition, distinguishing genuine ssDNA genomes from contaminating sequences in metagenomic datasets (e.g. from commercial kits) has been an unresolved issue for years. Here, we present CRESSENT (CRESS-DNA Extended aNnotation Toolkit), a comprehensive and modular bioinformatic pipeline focused on ssDNA virus 'genome-to-analysis' and annotation. The pipeline integrates multiple functionalities organized into several modules: sequence dereplication, decontamination, phylogenetic analysis, …

Faculty, Staff and Students Publications

Background: Soil-transmitted helminths (STHs) are among the most common global parasitic infections, represent a significant worldwide public health burden, and remain a source of considerable morbidity in Latin America. Nematophagous fungi (NF), such as Arthrobotrys oligospora, naturally inhabit many soil types and are known for their ability to trap and kill nematodes using specialized hyphal structures or secreted enzymes and metabolites. As they prey on different developmental stages of helminths in soil, they may represent an ecological factor influencing helminth persistence and transmission dynamics.

Methods: Using an in vitro test, Toxocara cati eggs were exposed to A. oligospora. By using …

Faculty, Staff and Students Publications

Objectives: Dolichocolon (DC), classified under International Classification of Diseases, Tenth Revision (ICD-10) code Q43.8 ("Other specified congenital malformations of intestine"), refers to an elongated or redundant large intestine. Recent studies in adults indicate a role for dolichocolon in constipation and disorders of gut-brain interaction. Contrast enema (CE) imaging is commonly used to identify DC, typically defined as a sigmoid colon extending above, or a transverse colon descending below, the iliac crest line. Despite its potential relevance, the prevalence and clinical significance of DC in pediatric gastroenterology remain poorly understood.

Methods: This retrospective study assessed the prevalence of DC in pediatric …

Cyclic Amp-Dependent Regulation Of Ryanodine Receptors In Healthy And Diseased Hearts, Mohit M Hulsurkar, Isabelle Ong, Joshua A Keefe, Issam H Abu-Taha, Dobromir Dobrev, Xander H T Wehrens

Faculty, Staff and Students Publications

Cyclic adenosine monophosphate (cAMP) is a critical second messenger in cardiomyocytes, regulating essential cellular functions. Upon G-protein-coupled receptor stimulation, adenylyl cyclase (AC) synthesizes cAMP, which phosphodiesterase (PDE) enzymes subsequently degrade. Recent studies challenge the traditional view of uniform cAMP signaling, revealing nanodomain-specific regulation within cardiomyocytes. This localized cAMP signaling modulates key Ca2+-handling proteins, including ryanodine receptor type-2 (RyR2), through channel-bound protein kinases and PDEs. Additionally, nucleoside-diphosphate kinases (NDPKs), particularly NDPK-C, contribute to cAMP synthesis and RyR2 regulation. Elevated NDPK-C levels in failing hearts correlate with increased cAMP levels, enhanced sarcoplasmic reticulum Ca2+ release, and cardiac arrhythmias. Furthermore, cAMP influences the …
