“I Call For The Resurgence And Reclamation Of Our Indigenous Ways”: Institutional Landscapes, Resistance, And The Experiences Of Mmir Advocates, Sara Tehrani

Graduate Studies Theses and Dissertations 2026

Indigenous Peoples across Turtle Island experience disproportionately high rates of violence and homicide compared to other racial groups. Rooted in coloniality and sustained by Western institutions, this epidemic is recognized as the Missing and Murdered Indigenous Relatives (MMIR) crisis. In response, Indigenous women have mobilized the MMIR Movement to raise awareness and advocate for institutional change. Although scholarship on MMIR has expanded, limited research has explored the experiences of MMIR advocates. This study interrogates the institutional landscapes that shape MMIR advocacy and explores the resistance strategies advocates employ to address the crisis. Using reflexive thematic analysis, this study examines semi-structured …

Ex Vivo Assessment Of Keratinocytic Carcinomas Using A Fast Mid-Infrared Probe., Maria G Vazquez De Vasquez, Rebecca C Bradley, Charles L Hitchcock, Angela S Casey, Austin Cusick, James V Coe, Ronald Siegle

Ambulatory and Primary Care Articles

A fast mid-infrared spectral probe was used to record infrared (IR) spectra of fresh skin tissue removed from patients with biopsy-proven keratinocytic cancer (KC) during Mohs surgery. A 150-patient library of IR spectral data was obtained to see if KC on the epidermal side (outside) of tissue samples can be differentiated from adjacent nonmalignant tissue and normal skin. A linear support vector machine model minimized overtraining predicting the contributions to decisions at each step in the spectrum. Training with an equal cost for KC and nontumor cases samples demonstrated a KC sensitivity of 93% ± 5% and specificity 82% ± …

Faculty, Staff and Students Publications

Background: Despite growing evidence supporting deep brain stimulation (DBS) for treatment- resistant depression (TRD), how stimulation delivered across hemispheres or across multiple targets interact to shape large-scale network activity remains poorly characterized.

Objective: Using a unique opportunity to simultaneously stimulate the subcallosal cingulate (SCC) and ventral capsule/ventral striatum (VC/VS) in subjects with TRD while recording neural activity across putative prefrontal networks underlying depression via intracranial electrodes, we investigated whether bilateral or multi-target stimulation has additive, synergistic/super-additive, or antagonistic/sub-additive effects on power modulation across depression-related brain networks.

Methods: Four DBS leads, and ten stereo-electroencephalography (sEEG) leads were implanted in depression-related prefrontal …

Old Lesions And New Targets: Seeg-Identified Onsets In Traditionally Inoperable Epilepsy Lesions And Associated Surgical Outcomes, Yosef M Dastagirzada, Spencer Frome, Daniel J Curry, Howard L Weiner

Faculty, Staff and Students Publications

Background: Patients with epilepsy who do not respond to pharmacotherapy are often offered a noninvasive diagnostic workup to localize an epileptogenic focus that might be treated with resection, neuromodulation, or ablation. Yet in many cases, this evaluation fails to identify surgical candidates.

Summary: Patients with tuberous sclerosis, periventricular nodular heterotopia, or polymicrogyria may have clearly visible lesions on MRI, but the resulting epileptogenic onset zones/networks are often too complex for scalp electroencephalography to decode. Similarly, seizures arising from the cingulate gyrus originate in deep structures that are inaccessible to noninvasive techniques. In post-traumatic epilepsy without a dominant lesion such as …

Introduction: Hemispherotomy is an effective treatment for children with drug-resistant epilepsy (DRE). While hemispherotomy techniques and indications have evolved, access remains predominantly constrained to high-resource settings.

Methods: We performed a retrospective analysis of children who underwent hemispherotomy from 2011 to 2023 by a hybrid team, including local Panamanian and US neurologists, neurosurgeons, and EEG technicians and analyzed surgical, epilepsy, and quality of life (QoL) parameters. Follow-up data were collected according to the International Consortium for Health Outcomes Measurement (ICHOM) guidelines for children with epilepsy.

Results: Twenty-three children underwent hemispherotomy. The median age at surgery was 10 years (range 2-20). The …

The Role Of Hospitality In Neurosurgery, Yosef M Dastagirzada, Howard L Weiner

Faculty, Staff and Students Publications

Background: "Business, like life, is all about how you make people feel. It's that simple and it's that hard" says Danny Meyer, the restauranteur and CEO of the Union Square Hospitality Group in New York. Similarly, Maya Angelou famously said that people will never forget how you made them feel, though they may forget what you said or did. In neurosurgery, we are doing two things at once: something very technical and something very human. The core thesis of this hospitality philosophy is that whereas the technical aspect of our job is critically important, it represents 49% of our success. …

Comparative Outcomes Of Robotic Single-Port Vnotes Versus Robotic-Xi Assisted Single-Incision Transumbilical Surgery For Hysterectomy, Qiannan Yang, David Pasternak, Chunhua Zhang, Xiaoming Guan

Faculty, Staff and Students Publications

Introduction: This study was to evaluate the safety and feasibility of robotic single-port transvaginal natural orifice transluminal endoscopic surgery (RSP-vNOTES) compared with robotic Xi-assisted single-incision transumbilical surgery (RXi-SITS) for hysterectomy.

Method: A total of 405 patients was retrospectively analyzed, comprising 278 individuals who underwent RXi-SITS hysterectomy and 127 who underwent RSP-vNOTES hysterectomy.

Results: A significantly higher prevalence of endometriosis-associated concomitant procedures, including ovarian cystectomy, lesion excision, adhesiolysis, appendectomy, bowel shaving, and bowel oversew, was observed among patients undergoing RSP-vNOTES (all p < 0.05). The RXi-SITS group saw uterosacral ligament suspension and ovarian vein ligation more commonly performed (both p < 0.05). A multivariable linear regression approach was employed to account for heterogeneity in procedural complexity. Following multivariable adjustment, estimated blood loss, hysterectomy time, and postoperative pain outcomes were comparable between the two surgical approaches. In contrast, multivariable linear regression accounting for concomitant procedures demonstrated that the RXi-SITS approach was independently associated with a significantly prolonged total operative time, with an adjusted mean increase of 21.8 min compared with RSP-vNOTES (B = 21.83; 95% CI: 6.05-37.61; p = 0.007). This is despite unadjusted analyses showing a longer median operative time in the RSP-vNOTES group …

Time Pressures And Sociocultural Constraints Affecting Access To Early Abortion Care Under Texas' "6-Week" Ban, Kari White, Whitney Arey, Anna Chatillon, Anitra D Beasley, Cecili Chadwick, Asha Dane'el, Ophra Leyser-Whalen, Tracy A Weitz

Faculty, Staff and Students Publications

Introduction: In 2021, Texas Senate Bill 8 (SB8) prohibited abortion after detection of embryonic cardiac activity and was often referred to as a "6-week ban." Limited evidence exists about how these laws intersect with people's processes seeking pregnancy confirmation and navigating barriers to abortion care.

Methods: Between October 2021 and August 2022, we recruited Texans ≥ 15 years of age who were seeking abortion using online ads and flyers placed in out-of-state abortion-providing facilities. Participants completed in-depth interviews, and we coded transcripts using inductive and deductive coding. This analysis explores participants' discussions of time needed for pregnancy confirmation, decision making, …

Intercornual Distance And Postoperative Reproductive Outcomes In Moderate-To-Severe Intrauterine Adhesions: A Retrospective Cohort Study, Yifu He, Xingping Zhao, Huan Huang, Changfa Shu, Xiaoming Guan, Jia Guo, Dabao Xu

Faculty, Staff and Students Publications

Study question: Does intercornual distance (ICD), as reflected by intrauterine stent size during hysteroscopic adhesiolysis, have an association with reproductive outcomes and provide information for postoperative risk stratification in women with moderate-to-severe intrauterine adhesions?

Summary answer: A smaller ICD was independently associated with a lower likelihood of clinical pregnancy within 1 year of the final hysteroscopy and may offer additional information for postoperative risk stratification in women with moderate-to-severe intrauterine adhesions.

What is known already: Reproductive outcomes following treatment for moderate-to-severe intrauterine adhesions vary considerably. Existing severity classifications offer limited discrimination within this group. The potential association between ICD and …

Faculty, Staff and Students Publications

Background: Sjögren's Disease (SjD) is a chronic autoimmune condition characterized by lymphocytic infiltration of lacrimal glands (LG) and salivary glands (SG). In SG, these immune structures have properties of ectopic lymphoid structures (ELS) and appear to play a critical role in disease pathology. While the presence of ELS in patients' SG biopsies is linked to disease severity, their presence and composition in LG has not been well characterized.

Methods: The properties and time course of apparent ELS development in LG from the male non-obese diabetes free (NOR) sub-strain of the Non-Obese Diabetic (NOD) mice was investigated at stages encompassing early …

The thalamus is a heterogeneous structure crucial for corticocortical communication, affective–perceptual integration, motor preparation, and memory-related functions. Posttraumatic stress disorder (PTSD) is characterized by various symptoms that likely relate to thalamic functions. Group-level and individual differential structural covariance (SC) analyses were conducted on intrathalamic, thalamocortical, and thalamosubcortical volumetric networks by segmenting structural MRI data from 2,784 subjects (PTSD n = 1,306; controls n = 1,478) into 25 thalamic nuclei per hemisphere. We found that PTSD was associated with stronger intrathalamic and thalamocortical network strength and stronger SC between the limbic thalamus and the somatomotor and auditory thalamus. PTSD severity was …

The precise wiring of the nervous system relies on neurons extending their processes at the right time and place to find their appropriate synaptic partner. The mechanisms that determine when and where neurons extend their neurites during synaptogenesis remains a central question in the field. In the present study, we used a cell culture system coupled with live imaging to investigate the wiring mechanisms in the developing mouse retina. We focused on horizontal cells which are a class of interneurons in the outer mouse retina known to synapse selectively to the distinct types of photoreceptors. Previous research has shown horizontal …

Faculty, Staff and Students Publications

Introduction: Demodex blepharitis (DB) is a chronic ocular inflammation caused by Demodex mite infestation of the eyelid. DB is often misdiagnosed, as some of its clinical findings and patient-reported outcomes overlap with those of other ocular surface diseases. The Demodex Expert Panel on Treatment and Eyelid Health (DEPTH) has reached consensus on the symptomatology, diagnosis, and treatment of DB. Consensus findings from the DEPTH group include that collarettes are pathognomonic for DB and that lotilaner ophthalmic solution, 0.25%, the first and only FDA-approved treatment for DB, should be the first-line treatment for the disease. This case series highlights two instances …

Faculty, Staff and Students Publications

Isolated, non-congenital herpes simplex virus type 1 (HSV-1) keratitis in immunocompetent infants is exceedingly rare and may be easily misdiagnosed, leading to delays in appropriate antiviral therapy. This case is unique in that it describes HSV-1 keratitis in a healthy 9-month-old infant presenting without systemic illness, initially treated as bacterial conjunctivitis. The patient presented with unilateral eye pain, redness, and corneal opacification. Subsequent evaluation revealed HSV-1 keratitis, and the patient was treated with intravenous acyclovir in combination with topical moxifloxacin and topical ganciclovir, resulting in complete resolution of symptoms within one week. This case adds to the limited literature on …

Updates In Mycobacterial Keratitis Diagnosis And Treatment, Uma L Balakrishnan, Ryan T Wallace, Patricia Chévez-Barrios, Alejandro Arboleda, Masih U Ahmed

Faculty, Staff and Students Publications

Mycobacterial keratitis is an uncommon but challenging form of infectious keratitis, often associated with postsurgical eyes. Clinical presentation is variable and may be difficult to recognize, resulting in delays in diagnosis and challenges in management. Traditional diagnostic techniques from corneal scrapings are limited by slow organism growth and may yield negative results. Treatment is challenging due to antimicrobial resistance and typically requires prolonged multidrug therapy. Advances in diagnostic modalities, antimicrobial therapies, surgical approaches, and adjunctive treatments such as corneal crosslinking have improved clinicians' ability to mitigate or avoid severe visual consequences. Despite these developments, optimal management strategies remain incompletely defined, …

Professionalism In Practice: A Novel Approach To Integrating Small Doses Of Case-Based Professionalism Education Into Monthly Grand Rounds., Allison H Taylor, Andrew Caruso, Kelley Arredondo, Ellen M Friedman, Stacey R Rose

Faculty, Staff and Students Publications

Introduction: Professionalism is a critical construct across the health professions, though learners and faculty report feeling underprepared to navigate difficult situations; education in professionalism is challenged by the absence of a universal definition, time constraints due to overcrowded curricula, and the lack of consistent messaging to learners and faculty.

Methods: Professionalism in Practice (PiP) was developed to provide small doses (∼5 minutes) of case-based professionalism education as part of an existing educational forum (Grand Rounds) to optimize attendance of both learners and faculty. Each vignette highlighted a common professionalism challenge and was aligned with an AAMC professional competency. Sessions were …

Functional Analysis Of Genes Enriched In Male Reproductive Organs: Validation Via Fertility Assessment Of 14 Knockout Mouse Lines, Kazumasa Takemoto, Katarzyna Kent, Kaori Nozawa, Shingo Tonai, Ahn H Pham, Terumi Fujimoto, Thomas X Garcia, Martin M Matzuk, Masahito Ikawa, Keizo Tokuhiro

Faculty, Staff and Students Publications

Tissue-restricted gene expression serves as a key indicator of functional importance within specific organs. Despite advances in high-throughput sequencing and genome editing over the past decade, this principle remains the gold standard for identifying candidate genes for functional studies. In reproductive biology, testis-restricted expression is anticipated to indicate genes crucial for gametogenesis, given the conserved features shared between spermatogenesis and oogenesis. Concurrently, rapid evolution of spermatogenesis-related genes is well documented and thought to arise through duplication and subsequent mutation of ubiquitously expressed genes. In this study, we established 14 knockout (KO) mouse lines for male reproductive organ-enriched genes, all of …

A Strategy To Identify Biliary Atresia Efficiently: A Perspective From A Texas Center, Sanjiv Harpavat, Tebyan A Rabbani, Ashley M Upton, Sridevi Devaraj, Jose A Hernandez, Benjamin L Shneider

Faculty, Staff and Students Publications

Infants with biliary atresia are often diagnosed after 60 days of life because the disease is difficult to detect in its early stages. However, infants treated before 30-45 days of life have the best long-term outcomes. To help accelerate the biliary atresia diagnosis, we have developed a streamlined strategy that involves two sequential tests: (1) direct or conjugated bilirubin measurements and (2) a feeding abdominal ultrasound exam. In this review, the strategy is shared to encourage others to provide feedback as well as to consider incorporating portions into their own clinical workflows.

Challenges In The Diagnosis Of Concurrent T-Lymphoblastic Leukemia/Lymphoma And Thymic Neuroendocrine Carcinoma: A Case Report, Kristen Oliveira, Mary Doan, Ying Pei, Marwan Yared, Songlin Zhang

Faculty, Staff and Students Publications

The co-occurrence of T-lymphoblastic leukemia/lymphoma and thymic neoplasia is a rare event that can present a diagnostic challenge. In this case report, we describe a 31-year-old man who was found to have thymic neuroendocrine carcinoma and T-lymphoblastic leukemia/lymphoma 2 years after initial treatment for T-lymphoblastic leukemia/lymphoma. The thymic neuroendocrine carcinoma was initially detected in a malignant pleural effusion, and a retrospective review of a preceding lung biopsy suggested the involvement of both tumors within one tissue sample. Immunohistochemical analysis was imperative in highlighting these two elements because despite their unique cytomorphological characteristics, a limited amount of each component was seen …
