Gallbladder Decompression And Hydrodissection As Adjuncts For Ablation Of Pericholecystic Hepatocellular Carcinomas, Taylor Hoffman, Arta Kasaeian, Johnathon Chung, Ashkan Berenji, David Wynne, Mohammad Ghasemi-Rad, David Léon

Faculty, Staff and Students Publications

Microwave ablation is an effective treatment for hepatocellular carcinoma, but tumors adjacent to extrahepatic organs carry a higher risk for thermal injury. Thermoprotective techniques such as hydrodissection and gallbladder decompression can reduce this risk and expand the range of lesions amenable to percutaneous treatment. We present a case of a 68-year-old woman with hepatocellular carcinoma in hepatic segment V, with partial treatment response from prior transarterial chemoembolization. Due to the lesion's proximity to the gallbladder and transverse colon, microwave ablation was performed with concurrent ultrasound- and CT-guided gallbladder decompression and hydrodissection. The ablation was technically successful without post-procedural complications. At …

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 …

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 …

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 …

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 …

The senescent cell (SC) fate is linked to aging, multiple disorders and diseases, and physical dysfunction. Senolytics, agents that selectively eliminate 30%-70% of SCs, act by transiently disabling the senescent cell antiapoptotic pathways (SCAPs), which defend those SCs that are proapoptotic and pro-inflammatory from their own senescence-associated secretory phenotype (SASP). Consistent with this, a JAK/STAT inhibitor, Ruxolitinib, which attenuates the pro-inflammatory SASP of senescent human preadipocytes, caused them to become "senolytic-resistant". Administering senolytics to obese mice selectively decreased the abundance of the subset of SCs that is pro-inflammatory. In cell cultures, the 30%-70% of human senescent preadipocytes or human umbilical …

Purpose: Treating obesity in complex disorders requires individualized health management plans. Effective obesity management in the Smith-Magenis syndrome (SMS) population has multiple inherent barriers related to their cognitive impairments, anxiety, behavioral disturbances, and sleep disorders. However, to date, no research exists related to strategies caregivers successfully employ to help individuals with SMS manage their food intake and mitigate associated behaviors.

Methods: We performed a qualitative thematic analysis of group interviews from 23 caregivers representing 21 individuals with SMS. Hybrid thematic analysis revealed that successful strategies employed by caregivers in this unique population revolved around a global theme of Empowering Through …

Amino Acids And Lean Mass Accretion In Preterm Neonates, Antonio C Ramos Dos Santos, Marta L Fiorotto, Teresa A Davis

Faculty, Staff and Students Publications

Purpose of review: This review evaluates recent evidence on how total protein and energy intake, amino acid composition, and nutrient delivery modality influence protein synthesis in preterm neonates, with the goal of informing nutritional strategies to support optimal lean mass accretion and growth.

Recent findings: Preterm neonates exhibit anabolic resistance to feeding due to impaired insulin and amino acid signaling in skeletal muscle. Enteral nutrition, especially fortified human milk, supports better lean mass accretion and neurodevelopment than parenteral nutrition. Intermittent bolus feeding and pulsatile leucine supplementation during continuous feeding further enhance mTORC1-dependent translation initiation signaling and protein synthesis efficiency in …

In AML with 3q26.2 rearrangements (r) the distal GATA2 hematopoietic enhancer becomes aberrantly relocated leading to activation of EVI1 expression. EVI1 is a transcriptional regulator that plays a role in proliferation and maintenance of a stem cell-like phenotype in AML. BRG1 (SMARCA4) and BRM (SMARCA2) are the mutually exclusive ATPases of the BAF (BRG1/BRM-associated factor) chromatin remodeling complexes. They regulate access to enhancers/promoters and gene-expressions orchestrating AML stem/progenitor cell proliferation and differentiation. AML with 3q26.2 rearrangements are clinically challenging and prognosis remains very poor. FHD-286 is an orally bioavailable, selective inhibitor of BRG1/BRM under clinical development in AML. Present studies …

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 …

Astrocytic Sox9 Overexpression In Alzheimer’S Disease Mouse Models Promotes Aβ Plaque Phagocytosis And Preserves Cognitive Function, Dong-Joo Choi, Sanjana Murali, Wookbong Kwon, Junsung Woo, Eun-Ah Christine Song, Yeunjung Ko, Debosmita Sardar, Brittney Lozzi, Yi-Ting Cheng, Michael R Williamson, Teng-Wei Huang, Kaitlyn Sanchez, Joanna Jankowsky, Benjamin Deneen

Faculty, Staff and Students Publications

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 …

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, …

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 …

Faculty, Staff and Students Publications

Introduction: Modeling safe sleep in the neonatal intensive care unit (NICU) increases the likelihood that parents will follow these practices after discharge. Many NICU infants are put to sleep unsafely, and unsafe sleep practices are the leading cause of nonnatural death among children locally. We created safe sleep standards for infants older than 32 weeks based on national guidelines: infants should be placed supine in a flat, empty crib and should never be swaddled loosely. We aimed to increase the weekly percentage compliance with safe sleep recommendations from a baseline of 58% (0.58 compliant) to 85% (0.85 compliant) by March …
