Anesthetic Management Of A Patient With A Vagal Nerve Stimulator And Poorly Controlled Seizures, Lakshmi N. Kurnutala, Nickhil Rugnath, Rhea Arora, Ryan Nazari

Student Publications

Vagal nerve stimulation (VNS) is an emerging adjunctive therapy for patients with drug-resistant epilepsy. While it can reduce seizure frequency, it rarely results in complete seizure control. It introduces unique challenges in the perioperative setting, including risks of intraoperative seizures, VNS-induced bradyarrhythmias, and respiratory complications.

We present a complex case of a 63-year-old woman with treatment-resistant epilepsy managed with VNS, who underwent open reduction and internal fixation (ORIF) for bilateral femur fractures. On the night before surgery, the patient experienced a tonic-clonic seizure with status epilepticus on the surgical floor, managed with intravenous levetiracetam and midazolam. Despite neurology clearance, intraoperative …

Faculty, Staff and Student Publications

Background: HER2-low breast cancer (HER2 immunohistochemical [IHC] score 1+, or IHC 2+ without HER2 gene amplification) is distinct from HER2-positive and HER2-0 breast cancer (IHC 0), with a differing prognosis and specific therapeutic options. The DESTINY-Breast04 trial demonstrated notable efficacy of the HER2 antibody-drug conjugate trastuzumab deruxtecan over standard chemotherapy in patients with metastatic breast cancer (MBC) defined as HER2-low. More recently, the DESTINY-Breast06 trial confirmed this benefit in hormone receptor-positive and HER2-ultralow (less than 1+, but with ≤10% of infiltrating cancer cells showing incomplete and faint/weak membrane staining) cases, prompting re-evaluation of HER2 diagnostic thresholds and treatment strategies.

Diet-Responsive Genetic Determinants Of Intestinal Colonization In The Yeast Candida Albicans, Musfirat Shubaita, Mazen Oneissi, Elena Lindemann-Pérez, Cecilia Fadhel Alvarez, Anne-Marie Krachler, Diana M Proctor, J Christian Pérez

Faculty, Staff and Student Publications

Dietary components influence microbial composition in the digestive tract. Although often viewed as energy sources, dietary components are likely to shape microbial determinants of intestinal colonization beyond metabolism. Here, we report that a dietary long-chain fatty acid enhances the yeast Candida albicans colonization of the murine gut partly by eliciting modifications to the fungal cell surface. Mice fed an oleic acid-rich diet were readily colonized by C. albicans and exhibited higher fungal load in feces compared with rodents fed an isocaloric control diet. Surprisingly, β-oxidation, a catabolic process to break down fatty acids for energy production, was dispensable for C. …

A Neutrosophic Homological-Gröbner Framework For Ai-Driven Media Education Evaluation, Mona Gharib, Hafiz Muhammad Athar Farid, José M. Merigó, Muhammad Riaz

Sustainable Machine Intelligence Journal

The integration of artificial intelligence (AI) with media technologies has transformed teaching in Journalism and Communication, introducing new challenges for quality evaluation. Traditional assessment methods fail to capture the uncertainty, inconsistency, and incompleteness inherent in modern educational data. This paper proposes a Neutrosophic Homological–Gröbner Framework, which unifies three perspectives: neutrosophic sets to encode uncertain evidence, homological algebra to analyze structural coherence, and Gröbner bases to systematically simplify interdependent evaluation rules.

Within this framework, diverse evidence is encoded into neutrosophic triplets, daggregate into course-level indicators, and organized into neutrosophic chain complexes, where Betti indices reveal coherence and fragmentation. Educational policies are …
