Age-Related Variations Of The Hemodynamic Response Function Spatially Resolved Across Human Cerebral Cortex, Nooshin J Fesharaki, Amanda Taylor, David Ress

Faculty, Staff and Students Publications

Normal aging leads to regional vascular and neural alterations. Age-related impairments in neurovascular coupling (NVC) affect the blood-oxygen-level-dependent (BOLD) hemodynamic response function (HRF) measured with functional magnetic resonance imaging, causing changes in both amplitude and temporal dynamics. Previously, global, systematic age-related changes in HRF characteristics were demonstrated, consistent with known microvascular aging effects. In this follow-up study, a standard space was used to compare spatially resolved cortical HRF dynamics between sex-balanced groups of young and older adults. The results showed substantial age-related differences in both HRF amplitude and timing across distinct cortical regions. Nearly twice as much cortical area exhibited …

There is growing recognition of the need for human-based models of the nervous system and its diseases. Studies have investigated the electrophysiological properties of neurons in ex vivo human brain tissue, but the maintenance of other cell types remains unclear. We therefore used single-nucleus RNA sequencing of six patient samples to determine how well various cell types maintain their transcriptional identities over two weeks in organotypic slice culture (day 0, with 83 501 nuclei, and day 14, with 45 738). For each patient sample (two pediatric temporal lobectomies, one adult frontal cortex, two glioblastomas, and one medulloblastoma), we generated correlations …

Background: Recent trials have furthered uncertainty regarding the endovascular benefit for medium vessel occlusions (MeVO). Stent retrievers (SR) were employed in the first attempt in most interventional arm participants. We sought to compare outcomes in acute MCA M2 occlusions between frontline aspiration and SR, and to delineate procedural and anatomical covariates associated with differential treatment effect.

Methods: Retrospective analysis of a multicenter stroke thrombectomy cohort identified cases of MT for M2 occlusions. Unmatched and propensity score-matched (PSM) cohorts were generated comparing frontline aspiration to standalone and combined SR. The primary outcome was functional independence (mRS 0-2) at 90 days. Recanalization, …

Introduction: Endovascular thrombectomy (EVT) is an effective treatment for basilar artery occlusion (BAO) stroke in select patients. While there is a growing body of literature suggesting that advanced imaging modalities such as computed tomography perfusion (CTP) and magnetic resonance (MR) may not be necessary for selecting anterior circulation large vessel occlusion stroke patients for EVT, whether advanced imaging may be superior to conventional imaging (non-contrast CT and CT angiography) in identifying good treatment candidates among BAO patients is less clear.

Patients and methods: This was a multicenter retrospective cohort study of BAO EVT patients treated from 2013 to 2022 in …

Astrocytes play essential roles in the brain, and their dysfunction is associated with nearly every form of neurological disease. Despite their ubiquity, knowledge of how astrocytes contribute to disease pathogenesis is incomplete; accordingly, harnessing their biology toward therapeutics remains a major challenge. Here we show that the transcription factor Sox9 plays a context-specific role in maintaining astrocyte function and circuit activity in the aging hippocampus and Alzheimer's disease (AD) models. We found that Sox9 overexpression in astrocytes in AD models clears existing amyloid beta (Aβ) plaques and preserves cognitive function. Mechanistically, Sox9 promotes the phagocytosis of Aβ plaques by astrocytes …

Mapping The Structural Connections Between The Anterior Cingulate Cortex And The Insula/Ventrolateral Prefrontal Cortex.Mapping The Structural Connections Between The Anterior Cingulate Cortex And The Insula/Ventrolateral Prefrontal Cortex, Wei Tang, Javier Guaje, Shreyas Fadnavis, Sarah R Heilbronner, Eleftherios Garyfallidis

Faculty, Staff and Students Publications

The anterior cingulate cortex (ACC) is functionally closely related with the insula and the ventral lateral prefrontal cortex (vlPFC). The ACC and insula are the main hubs of the salience network, a set of functionally related brain regions involved in detecting salient stimuli and coordinating inter-network communication, while communication between ACC and vlPFC is closely linked to inhibitory control. However, despite strong indirect evidence from nonhuman primate (NHP) tract tracing, the structural connections between the ACC and the insula/vlPFC remain poorly understood in the human brain, in part because standard approaches fail to capture this projection. In this study, we …

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 …

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 …

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 …

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, …

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.
